Description

車輪保持單元及嬰兒車 Wheel holding unit and baby carriage 發明領域 Field of invention

本發明是有關於一種車輪保持單元，以及，具有該車輪保持單元之嬰兒車，而該車輪保持單元具有：將車輪保持成可旋轉之旋轉體、及以與車輪之旋轉軸線不平行的軸線為中心而將旋轉體支持成可旋轉的固定體。 The present invention relates to a wheel holding unit and a baby carriage provided with the wheel holding unit, and the wheel holding unit includes: a wheel holding a rotatable rotating body; and an axis which is not parallel to the rotation axis of the wheel is The center supports the rotating body as a rotatable fixed body.

發明背景 Background of the invention

習知，作為保持嬰兒車之前輪的車輪保持單元，廣泛地使用了所謂的腳輪，其是具有將車輪保持成可旋轉之旋轉體、及以與車輪之旋轉軸線不平行的軸線為中心而將旋轉體支持成可旋轉的固定體。如美國專利US5,215,320B所揭示地，上述車輪保持單元中，將用以限制旋轉體相對於固定體之旋轉的鎖定構件典型地在固定體之收容部內設置成可滑動。且，為了確實使鎖定構件滑動，固定體之收容部與鎖定構件之間形成有比較大的間隙。 Conventionally, as a wheel holding unit that holds a front wheel of a stroller, a so-called caster is widely used, which has a rotating body that holds the wheel so as to be rotatable, and uses an axis that is not parallel to the rotation axis of the wheel as a center. The rotating body is supported as a rotatable fixed body. As disclosed in U.S. Patent No. 5,215,320B, in the above-mentioned wheel holding unit, a locking member for restricting the rotation of the rotating body relative to the fixed body is typically provided to be slidable in the receiving portion of the fixed body. In addition, in order to surely slide the lock member, a relatively large gap is formed between the accommodation portion of the fixed body and the lock member.

又以往至今，為人所知的有：把手可搖動於比垂直軸更朝後方傾斜之第1位置(背面推壓位置)、與側面視點下比垂直軸更朝前方傾斜之第2位置(相對面推壓位置)之間的嬰兒車。當考慮此種嬰兒車之操作性時，宜在前腳與後 腳均使用作為所謂腳輪的車輪保持單元，且，安裝於進行方向前方側之腳之車輪保持單元之旋轉體相對於固定體可旋轉，並限制安裝於進行方向後方側之腳之旋轉體相對於固定體的旋轉。 From now on, it is known that the handle can be swung at the first position (backward pressing position) tilted more rearward than the vertical axis, and the second position (relatively tilted frontward than the vertical axis in the side view) Face pushing position). When considering the operability of this stroller, Both feet use a wheel holding unit called a caster, and the rotating body of the wheel holding unit attached to the foot in the forward direction is rotatable relative to the fixed body, and the rotating body attached to the foot in the rearward direction is restricted from rotating Rotation of the fixed body.

然而，當固定體之收容部與鎖定構件之間的間隙較大時，鎖定構件之動作就會有晃動產生，便無法使鎖定構件安定地動作。又，根據把手之位置而使鎖定構件動作之嬰兒車中，頻繁地進行鎖定構件之動作，故，特別是根據把手之位置而使鎖定構件自動地動作之嬰兒車中，為了確保非手動之鎖定構件之順利的動作，由於必須將固定體之收容部與鎖定構件之間的間隙設定為較大，因此該問題會變得更加顯著。 However, when the gap between the accommodating portion of the fixed body and the lock member is large, the movement of the lock member will be shaken, and the lock member cannot be operated stably. In addition, in a baby carriage in which the locking member is operated according to the position of the handle, the locking member is frequently operated. Therefore, particularly in a baby carriage in which the locking member is automatically operated according to the position of the handle, in order to ensure non-manual locking This problem becomes more significant because the smooth movement of the member requires a large gap between the receiving portion of the fixed body and the lock member.

本發明是考慮以上之點而成者，目的在於提供一種車輪保持單元及嬰兒車，該車輪保持單元可使鎖定構件安定地動作，藉此，便可更加確實地進行旋轉體相對於固定體可旋轉之狀態與旋轉體相對於固定體不可旋轉之狀態的切換。 The present invention has been made in consideration of the above points, and an object of the present invention is to provide a wheel holding unit capable of operating a lock member in a stable manner and a stroller, thereby enabling a rotating body to be more reliably compared with a fixed body.

Rotate for the center.

而，本說明書中，對於嬰兒車10與其構成元件之「前」、「後」、「上」及「下」的用語在無特別指示時，是意味著以搭乘處於展開狀態之嬰兒車10的嬰幼兒為基準的「前」、「後」、「上」及「下」。因此，所謂的「前後方向」是將圖1~圖4之紙面的左下與右上連結的方向，並且與連結圖5與圖6之紙面左右的方向相當。且，只要無特別指示，所謂的「前」是乘車之嬰幼兒所朝向之側，為圖1~圖4之紙面的左下側，並且圖5與圖6之紙面的左側為「前側」。另一 方面，所謂的「上下方向」是與前後方向正交並且與放置嬰兒車10之面(地面)正交的方向。因此，放置嬰兒車10之面為水平面時，所謂的「上下方向」是指垂直方向。又，所謂的「橫向」與「寬度方向」是指與「前後方向」與「上下方向」之均正交的方向。進而，針對「右」與「左」亦個別意味著以搭乘嬰兒車10之嬰幼兒為基準之橫向或寬度方向之「右」與「左」的情形。 However, in this specification, the terms "front", "rear", "up", and "down" of the stroller 10 and its constituent elements mean that the stroller 10 in the unfolded state is used without special instructions. "Before", "After", "Up" and "Bottom" based on infants and young children. Therefore, the so-called "front-rear direction" is a direction connecting the lower left and upper right of the paper surface of Figs. 1 to 4 and is equivalent to the direction connecting the left and right of the paper surface of Figs. In addition, as long as there is no special instruction, the so-called "front" is the side on which the infants and young children on the vehicle face, which is the lower left side of the paper surface of Figs. another On the one hand, the so-called "up and down direction" is a direction orthogonal to the front-rear direction and orthogonal to the surface (ground) on which the stroller 10 is placed. Therefore, when the surface on which the stroller 10 is placed is a horizontal plane, the so-called "up and down direction" means the vertical direction. The "lateral direction" and the "width direction" refer to directions orthogonal to both the "front-rear direction" and the "up-down direction". Furthermore, the terms "right" and "left" also mean "right" and "left" in the lateral or width direction based on the infants and infants who ride the stroller 10, respectively.

如圖所示，嬰兒車10整體而言是以沿著前後方向來延伸之寬度方向中心面為中心而大致對稱的構成。以下，參照圖式，並且針對本實施形態之嬰兒車10的各構成元件來說明。 As shown in the figure, the stroller 10 as a whole has a substantially symmetrical configuration with the widthwise center plane extending in the front-rear direction as a center. Hereinafter, each component of the baby carriage 10 of this embodiment will be described with reference to the drawings.

<<嬰兒車本體與把手>> << Baby stroller body and handle >>

嬰兒車本體11具有：具有前腳20與後腳21之本體框15、與透過軸構件13而連接於本體框15之布片支持單元40。布片支持單元40透過軸構件13，相對於本體框15安裝成可旋動。藉此，隨著嬰兒車10之折疊動作與展開動作之布片支持單元40相對於本體框15便可相對動作。布片支持單元40相對於本體框15的旋動中心與軸構件13之軸線方向da一致，特別是所圖示之例中，與嬰兒車10之寬度方向成為平行。又，本實施形態中，把手70透過軸構件13，在嬰兒車本體11安裝成可搖動。把手70相對於嬰兒車本體11的旋動中心與軸構件13之軸線方向da一致，因此與嬰兒車10之寬度方向成為平行。首先，針對嬰兒車本體11之布片支持單元40來說明，接著，針對嬰兒車本體11之本體框15來 說明，之後，針對把手70來說明。 The stroller body 11 includes a body frame 15 having a front foot 20 and a rear foot 21, and a cloth sheet supporting unit 40 connected to the body frame 15 through a shaft member 13. The cloth sheet supporting unit 40 is rotatably attached to the main body frame 15 through the shaft member 13. With this, the cloth support unit 40 can move relative to the main body frame 15 with the folding and unfolding movements of the stroller 10. The rotation center of the cloth sheet supporting unit 40 with respect to the main body frame 15 coincides with the axial direction da of the shaft member 13, and is particularly parallel to the width direction of the stroller 10 in the illustrated example. In the present embodiment, the handle 70 passes through the shaft member 13 and is attached to the stroller body 11 so as to be swingable. The rotation center of the handle 70 with respect to the stroller body 11 coincides with the axial direction da of the shaft member 13, and is therefore parallel to the width direction of the stroller 10. First, the cloth support unit 40 of the stroller body 11 will be described, and then, the body frame 15 of the stroller body 11 will be described. The description will be made later with respect to the handle 70.

<布片支持單元40> <Fabric support unit 40>

如圖2、圖3、圖8~10所詳示，布片支持單元40包含有：成為從下方與搭乘嬰兒車10之嬰幼兒臀部，相對面的座面部支持元件50、以及成為從後方與搭乘嬰兒車10之嬰幼兒背部相對面的靠背部支持元件60。靠背部支持元件60相對於座面部支持元件50為可搖動(可傾倒)。藉此，嬰兒車10可傾斜動作。而，靠背部支持元件60之傾斜角度藉由將通過靠背部支持元件60背面且安裝於本體框15之傾斜調節帶(未圖示)的長度加以調節而可控制。 As shown in detail in Figs. 2, 3, and 8-10, the cloth support unit 40 includes a seat support member 50 that becomes the hips of an infant from below and riding the stroller 10, and a seat support member 50 that faces the rear. The backrest support element 60 on the back of the infant 10 on the stroller 10. The backrest support member 60 is swingable (pourable) relative to the seat surface support member 50. Thereby, the stroller 10 can be tilted. The tilt angle of the backrest support member 60 can be controlled by adjusting the length of a tilt adjustment belt (not shown) that passes through the back of the backrest support member 60 and is mounted on the main body frame 15.

座面部支持元件50具有在其後方部分朝寬度方向彼此分開地來配置之一對後方連接部54。另一方面，靠背部支持元件60具有在其下方部分於寬度方向彼此分開地來配置之一對下方連接部62。左側後方連接部54與左側下方連接部62卡合，右側後方連接部54與右側下方連接部62卡合。藉由後方連接部54與下方連接部62之卡合，靠背部支持元件60相對於座面部支持元件50連接成可搖動。所圖示之例中，一對後方連接部54位於一對下方連接部62之寬度方向內側，但不限於該例，例如亦可為一對下方連接部62位於一對後方連接部54之寬度方向內側。 The seat surface support member 50 has a pair of rear connecting portions 54 arranged at the rear portion thereof apart from each other in the width direction. On the other hand, the backrest support member 60 has a pair of lower connection portions 62 that are arranged separately from each other in a width direction at a lower portion thereof. The left rear connection portion 54 is engaged with the left lower connection portion 62, and the right rear connection portion 54 is engaged with the right lower connection portion 62. By engaging the rear connecting portion 54 and the lower connecting portion 62, the backrest support member 60 is swingably connected to the seat surface support member 50. In the illustrated example, the pair of rear connection portions 54 are located on the inner side in the width direction of the pair of lower connection portions 62, but are not limited to this example. For example, the pair of lower connection portions 62 may be located in the width of the pair of rear connection portions 54 Direction inside.

如圖13所示，後方連接部54與下方連接部62個別形成有：軸構件13所貫通之貫通孔50a、貫通孔60a。從圖10~圖12可理解到，軸構件13朝寬度方向分開地來配置一對。各軸構件13會貫通成為對應之側的後方連接部54與下 方連接部62的貫通孔50a、貫通孔60a並延伸。 As shown in FIG. 13, the rear connection portion 54 and the lower connection portion 62 are individually formed with a through hole 50 a and a through hole 60 a through which the shaft member 13 penetrates. As can be understood from FIG. 10 to FIG. 12, the pair of shaft members 13 are arranged separately in the width direction. Each shaft member 13 passes through the rear connecting portion 54 and the lower side corresponding to the corresponding side. The through holes 50 a and 60 a of the square connection portion 62 extend in parallel.

又，下方連接部62設有：設於以軸構件13之軸線方向da為中心之圓周上且朝軸線方向da突出的凸起(第1凸起)62a。凸起62a具有：位於以軸線方向da為中心之圓周的全周上或一部分上的凸起面(外表面)。另一方面，後方連接部54形成有承接凸起62a之凸起面62a1的凸起承接部54a。凸起承接部54a具有：位於以軸構件13之軸線方向da為中心之圓周的全周上或一部分上的凸起承接面54a1。後方連接部54與下方連接部62相對旋動時，凸起62a之凸起面62a1與凸起承接部54a之凸起承接面54a1會相對滑動。如上所述，藉由凸起62a與凸起承接部54a卡合，靠背部支持元件60相對於座面部支持元件50便可搖動。特別是，凸起62a延伸於以軸構件13之軸線方向da為中心的圓周上，故，靠背部支持元件60相對於座面部支持元件50的搖動軸線會與軸構件13之軸線方向da一致。又，藉由設於後方連接部54與下方連接部62其中一方的各凸起62a嵌入至設於後方連接部54與下方連接部62另一方之對應側的凸起承接部54a，例如即使在由軸構件13貫通之前的狀態下，座面部支持元件50與靠背部支持元件60亦是以可相對搖動之狀態彼此連接。而，與所圖示之例不同，亦可在後方連接部54設置凸起，在下方連接部62設置凸起承接部。 Further, the lower connecting portion 62 is provided with a protrusion (first protrusion) 62 a provided on a circumference centered on the axial direction da of the shaft member 13 and protruding in the axial direction da. The projection 62a has a projection surface (outer surface) located on the entire circumference or a part of the circumference centered on the axis direction da. On the other hand, the rear connecting portion 54 is formed with a convex receiving portion 54a that receives the convex surface 62a1 of the convex 62a. The convex receiving portion 54 a has a convex receiving surface 54 a 1 located on the entire circumference or a part of the circumference of the circumference centered on the axial direction da of the shaft member 13. When the rear connecting portion 54 and the lower connecting portion 62 rotate relatively, the convex surface 62a1 of the protrusion 62a and the convex receiving surface 54a1 of the convex receiving portion 54a will relatively slide. As described above, by engaging the protrusion 62a with the protrusion receiving portion 54a, the backrest support member 60 can be swung relative to the seat surface support member 50. In particular, since the protrusion 62 a extends on the circumference centered on the axis direction da of the shaft member 13, the swing axis of the backrest support member 60 relative to the seat surface support member 50 will coincide with the axis direction da of the shaft member 13. Further, each projection 62a provided on one of the rear connection portion 54 and the lower connection portion 62 is fitted into the projection receiving portion 54a provided on the corresponding side of the other side of the rear connection portion 54 and the lower connection portion 62. In a state before being penetrated by the shaft member 13, the seat surface support member 50 and the backrest support member 60 are also connected to each other in a state capable of relatively swinging. However, unlike the illustrated example, a protrusion may be provided in the rear connection portion 54, and a protrusion receiving portion may be provided in the lower connection portion 62.

圖13所示之例中，靠背部支持元件60之下方連接部62形成有：朝寬度方向之內側突出的凸起62a。凸起62a會形成軸構件13所貫通之貫通孔60a的一部分。朝寬度方向 內側突出之凸起62a會依環狀圍繞於以軸構件13之軸線方向da為中心的圓周上。另一方面，座面部支持元件50之後方連接部54形成有：承接凸起62a之凸起承接部54a。凸起承接部54a是利用形成於後方連接部54之軸構件13所通過的貫通孔50a內周面來形成。因此，所圖示之例中，後方連接部54之貫通孔50a透過下方連接部62之凸起62a，承接軸構件13。根據上述形態，便可使沿著形成於靠背部支持元件60之貫通孔60a之軸線方向da的長度變長。因此，可抑制布片支持單元40相對於軸構件13的搖晃，並使透過軸構件13之布片支持單元40與本體框15的相對搖動變得順利。 In the example shown in FIG. 13, the lower connection portion 62 of the backrest support member 60 is formed with a protrusion 62 a protruding inward in the width direction. The protrusion 62 a forms a part of the through hole 60 a through which the shaft member 13 penetrates. Towards the width The protrusion 62 a protruding from the inner side is looped around the circumference centered on the axis direction da of the shaft member 13. On the other hand, the rear surface connection portion 54 of the seat surface support member 50 is formed with a projection receiving portion 54a that receives the projection 62a. The convex receiving portion 54 a is formed by an inner peripheral surface of the through hole 50 a through which the shaft member 13 formed in the rear connection portion 54 passes. Therefore, in the illustrated example, the through hole 50 a of the rear connection portion 54 passes through the protrusion 62 a of the lower connection portion 62 and receives the shaft member 13. According to the above aspect, the length in the axial direction da of the through hole 60a formed in the backrest support element 60 can be made longer. Therefore, it is possible to suppress the wobble of the cloth support unit 40 with respect to the shaft member 13, and to make the relative shaking of the cloth support unit 40 and the main body frame 15 passing through the shaft member 13 smooth.

以下，針對所圖示之本實施形態之座面部支持元件50與靠背部支持元件60進而詳述。座面部支持元件50具有：形成U字狀之座面部支持框51、個別安裝於座面部支持框51所成之U字之端部51a的框端構件53、及張開設置於座面部支持框51之基座布片55。而，基座布片55只在圖10顯示。 Hereinafter, the seat surface support element 50 and the backrest support element 60 of the illustrated embodiment will be further described in detail.

<<嬰兒車之整體性動作與作用>> << Overall action and function of baby carriage >>

接著，針對嬰兒車本體11與把手70帶來的嬰兒車10整體動作與作用效果來說明。首先，如以上構成而成之嬰兒車10可從圖1~6所示之展開狀態朝圖7所示之折疊狀態來折疊。折疊動作中，成為嬰兒車10之各構成元件會以朝寬度方向延伸之軸線為中心彼此旋動(樞轉、搖動)。 Next, the overall operation and effects of the stroller 10 brought by the stroller body 11 and the handle 70 will be described. First, the stroller 10 configured as described above can be folded from the unfolded state shown in FIGS. 1 to 6 to the folded state shown in FIG. 7. In the folding operation, the constituent elements that become the stroller 10 rotate (pivot, swing) with each other around an axis extending in the width direction.

具體而言，藉由將配置於第1位置之把手70暫時往後上方上拉，之後，朝下方壓下，使第3連桿元件28相對於後腳21，在圖5中朝順時針方向來旋動。隨著該操作，第1連桿元件22與布片支持單元40之座面部支持元件50相對於第2連桿元件24，在圖5中朝順時針方向來旋動。利用該操作，使把手70與前腳20在嬰兒車10之側面視點下接近而配置成大致平行，並且可使把手70之配置位置降低。如以上所述，可折疊嬰兒車10，便可使沿著嬰兒車10之前後方向與上下方向的尺寸小型化。另一方面，要使嬰兒車10從折疊狀態展開，只要進行與上述之折疊操作相反的順序即可。因此，該嬰兒車10中，布片支持單元40之一部分(具體而言，是座面部支持框51之側框部52a當中從端部51a到與前腳支持元件32之固接位置為止的部分)與前腳支持元件32在嬰兒車10之折疊操作時與嬰兒車10之展開操作時具有 作為一個連桿的功能。 Specifically, the handle 70 disposed at the first position is temporarily pulled up and upwards, and then pushed downward, so that the third link element 28 is moved clockwise with respect to the rear leg 21 in FIG. 5.

第1彈性構造體125與第2彈性構造體127藉由車輪保持器120之相對於支持塊體115的動作而變形。換言之，第1彈性構造體125與第2彈性構造體127藉由變形，將相對於車輪保持器120之支持塊體115之動作加以吸收，來發揮避震功能。在此，所謂的彈性構造體是意味著一種具有當接受外力時就會變形且當除去該外力時就會至少部分地復原成原本形狀之性質的構造體，因此，不只是橡膠或樹脂等之純彈性材料的塊體，如彈簧或如後述密封氣體之袋般在構造上表現出上述性質之物均可包含於彈性構造體。包含二個彈性構造體125、127之車輪保持單元100中，從表現優異之避震功能的觀點來看，宜滿足以下之條件a與 條件b之至少一方。以下之條件a與條件b可藉由在第1彈性構造體125與第2彈性構造體127之間以材料、構造、配置、可變形量等為不同的方式來構成第1彈性構造體125與第2彈性構造體127而實現。 The first elastic structure 125 and the second elastic structure 127 are deformed by the movement of the wheel holder 120 with respect to the support block 115. In other words, the first elastic structural body 125 and the second elastic structural body 127 are deformed to absorb the motion of the support block 115 with respect to the wheel holder 120 to exert the shock-absorbing function. Here, the term "elastic structure" means a structure that has the property of deforming when receiving an external force and at least partially returning to its original shape when the external force is removed. Therefore, it is not just rubber or resin. A block of a purely elastic material, such as a spring or a gas-sealed bag described later, which exhibits the above-mentioned properties in structure can be included in the elastic structure. In a wheel holding unit 100 including two elastic structures 125 and 127, from the viewpoint of excellent suspension performance, the following conditions a and At least one of the conditions b. The following conditions a and b can be configured by different materials, structures, arrangements, and deformation amounts between the first elastic structure 125 and the second elastic structure 127. The second elastic structure 127 is realized.

條件a： Condition a:

當車輪保持器120之相對於支持塊體115的動作開始時，首先，就只有第1彈性構造體125於車輪保持器120與支持塊體115之間來加壓而變形，當車輪保持器120相對於支持塊體115的動作進而進展時，除了第1彈性構造體125之外，第2彈性構造體127亦在車輪保持器120與支持塊體115之間來加壓而變形。 When the movement of the wheel retainer 120 relative to the support block 115 starts, first, only the first elastic structure 125 is pressed between the wheel retainer 120 and the support block 115 to deform it. When the wheel retainer 120 is deformed, When the operation with respect to the support block 115 is further advanced, in addition to the first elastic structure 125, the second elastic structure 127 is pressurized and deformed between the wheel holder 120 and the support block 115.

條件b： Condition b:

假設在車輪保持器120與支持塊體115之間只配置第1彈性構造體125時，使第1彈性構造體125變形而使車輪保持器120相對於支持塊體115只動作預定量所需要之力量的大小，會與假設在車輪保持器120與支持塊體115之間只配置第2彈性構造體127時，使第2彈性構造體127變形而使車輪保持器120相對於支持塊體115只動作預定量所需要之力量的大小不同。 If only the first elastic structure 125 is arranged between the wheel retainer 120 and the support block 115, it is necessary to deform the first elastic structure 125 to move the wheel retainer 120 relative to the support block 115 by a predetermined amount. The magnitude of the force is the same as when only the second elastic structure 127 is arranged between the wheel retainer 120 and the support block 115, the second elastic structure 127 is deformed and the wheel retainer 120 is opposed to the support block 115. The amount of force required to move a predetermined amount varies.

條件a中，車輪保持器120與支持塊體115相對動作時，在相對動作之初期階段，只有第1彈性構造體125變形，只有第1彈性構造體125對抗車輪保持器120及支持塊體115之相對動作。另一方面，當車輪保持器120與支持塊體115之相對動作進行時，第2彈性構造體127就會開始變形， 則第2彈性構造體127對抗車輪保持器120及支持塊體115之相對動作。例如，亦可為在車輪保持器120與支持塊體115之相對動作的初期階段，第2彈性構造體127與車輪保持器120及支持塊體115之至少一方為非接觸，當車輪保持器120與支持塊體115之相對動作進行時，第2彈性構造體127與車輪保持器120及支持塊體115之兩方接觸。亦可為在第2彈性構造體127對抗車輪保持器120及支持塊體115之相對動作時，第1彈性構造體125亦隨著車輪保持器120與支持塊體115之動作而繼續變形，第2彈性構造體127與第1彈性構造體125一起對抗車輪保持器120及支持塊體115的相對動作，或是，亦可為第1彈性構造體125已經不對抗車輪保持器120及支持塊體115的相對動作。 In condition a, when the wheel retainer 120 and the support block 115 are moved relative to each other, at the initial stage of the relative movement, only the first elastic structure 125 is deformed, and only the first elastic structure 125 opposes the wheel holder 120 and the support block 115 Relative action. On the other hand, when the relative movement of the wheel retainer 120 and the support block 115 proceeds, the second elastic structure 127 starts to deform, Then, the second elastic structure 127 opposes the relative movement of the wheel retainer 120 and the support block 115. For example, in the initial stage of the relative movement of the wheel retainer 120 and the support block 115, the second elastic structure 127 and the at least one of the wheel retainer 120 and the support block 115 may be non-contact. When the relative operation with the support block 115 is performed, the second elastic structure 127 is in contact with both the wheel holder 120 and the support block 115. When the second elastic structure 127 opposes the relative movement of the wheel retainer 120 and the support block 115, the first elastic structure 125 also continues to deform as the wheel retainer 120 and the support block 115 move. The 2 elastic structure 127 and the first elastic structure 125 together oppose the relative movement of the wheel retainer 120 and the support block 115, or the first elastic structure 125 may no longer oppose the wheel retainer 120 and the support block Relative action of 115.

條件b中，會設定成：車輪保持器120與支持塊體115只相對動作預定量時第1彈性構造體125之對抗相對動作的抗力、以及車輪保持器120與支持塊體115只相對動作相同量時第2彈性構造體127之對抗相對動作的抗力，會有所不同。 In condition b, it is set that the resistance of the first elastic structure 125 against the relative movement when the wheel retainer 120 and the support block 115 only move relative to each other by a predetermined amount, and the relative movement of the wheel retainer 120 and the support block 115 are the same. When measuring, the resistance of the second elastic structure 127 against the relative movement is different.

接著，將所圖示之本實施形態之彈性構造體125、127的構成，以及，與彈性構造體125、127之支持相關連之旋轉體110的構成加以說明。本實施形態中，第1彈性構造體125是利用橡膠等之彈性體126本身來構成。所圖示之彈性體126具有形成為凹部之承接部126a。車輪保持器120具有朝承接部126a嵌入之支持突起121a。利用支持突起121a與承接部126a的卡合，彈性體126所構成之第1彈性構 造體125便可保持於車輪保持器120。彈性體126形成為略圓柱狀，其長邊方向配置成延伸於車輪保持器120與支持塊體115之間。車輪保持器120相對於支持塊體115而搖動時，彈性體126便會沿著其長邊方向來壓縮。故，第1彈性構造體125對於車輪保持器120與支持塊體115之相對搖動的抗力，不會受到車輪保持器120與支持塊體115之相對搖動的進行的影響，而成為大致固定。 Next, the configuration of the elastic structures 125 and 127 of this embodiment and the configuration of the rotating body 110 related to the support of the elastic structures 125 and 127 will be described below.

The illustrated elastic body 126 has a receiving portion 126a formed as a recessed portion. The wheel retainer 120 has a support protrusion 121a fitted into the receiving portion 126a. The first elastic structure constituted by the elastic body 126 is caused by the engagement between the support protrusion 121a and the receiving portion 126a. The body 125 can be held on the wheel holder 120. The elastic body 126 is formed in a substantially cylindrical shape, and its longitudinal direction is arranged to extend between the wheel holder 120 and the support block 115. When the wheel retainer 120 is swung relative to the support block 115, the elastic body 126 is compressed along the longitudinal direction thereof. Therefore, the resistance of the first elastic structure 125 to the relative rocking of the wheel retainer 120 and the support block 115 is substantially fixed without being affected by the relative rocking of the wheel retainer 120 and the support block 115.

接著，針對第2彈性構造體127以及支持第2彈性構造體127之旋轉體110的構成來說明。如圖22與圖23所示，旋轉體110之支持塊體115具有朝上下方向延伸之板狀的支持板部116。另一方面，旋轉體110之車輪保持器120具有：樞接於支持塊體115之保持器基座121、與從保持器基座121之後方朝上方往上延伸的上方延出部122。如圖23所示，上方延出部122配置於與支持塊體115之支持板部116相對面的位置。而，用以保持車輪101之車軸113會保持於車輪保持器120當中保持器基座121與上方延出部122之連接處附近。又，上述之制動構件129樞接於上方延出部122。 Next, the configurations of the second elastic structure 127 and the rotating body 110 supporting the second elastic structure 127 will be described. As shown in FIGS. 22 and 23, the support block 115 of the rotating body 110 includes a plate-shaped support plate portion 116 extending in the vertical direction. On the other hand, the wheel retainer 120 of the rotating body 110 includes a retainer base 121 pivotally connected to the support block 115 and an upper extension 122 extending upward and upward from the rear of the retainer base 121. As shown in FIG. 23, the upper extension portion 122 is disposed at a position facing the support plate portion 116 of the support block 115. The axle 113 used to hold the wheel 101 is held near the connection between the holder base 121 and the upper extension 122 in the wheel holder 120. The braking member 129 is pivotally connected to the upper extending portion 122.

本實施形態中，第2彈性構造體127是作為密封氣體之袋而形成。成為袋之材料可由具有伸張性之橡膠或樹脂等來構成。所圖示之例中，第2彈性構造體127是作為密封氣體之樹脂製的袋128而形成。樹脂製袋128為透明或半透明。樹脂製袋128透過未圖示之扣件，由支持塊體115的支持板部116來支持。如圖24所示，樹脂製袋128大略形成為立方體狀，並形成凹部128a、階差部128b、及扣件承接 部128c。 In the present embodiment, the second elastic structure 127 is formed as a gas-sealed bag. The material used as the bag may be made of rubber or resin having stretchability. In the illustrated example, the second elastic structure 127 is formed as a resin bag 128 that seals the gas. The resin bag 128 is transparent or translucent. The resin bag 128 is supported by the support plate portion 116 of the support block 115 through a fastener (not shown). As shown in FIG. 24, the resin bag 128 is roughly formed into a cube shape, and has a recessed portion 128a, a stepped portion 128b, and a fastener receiving portion. Department 128c.

凹部128a形成於與車輪保持器120之上方延出部122相對面之側的面。凹部128a朝與車輪保持器120相對於支持塊體115之搖動軸線sc2正交的方向來延伸成直線狀。而，在上方延出部122，與凹部128a相對面之位置形成有凸部123。凸部123朝與車輪保持器120相對於支持塊體115之搖動軸線sc2正交的方向延伸成直線狀，並在車輪保持器120朝支持塊體115動作時，與凹部128a抵接。 The recessed portion 128 a is formed on a surface on the side opposite to the surface above the extended portion 122 of the wheel holder 120. The recessed portion 128 a extends linearly in a direction orthogonal to the swing axis sc2 of the wheel holder 120 relative to the support block 115. A convex portion 123 is formed on the upper extending portion 122 at a position facing the concave portion 128a. The convex portion 123 extends in a straight line in a direction orthogonal to the swing axis sc2 of the wheel holder 120 with respect to the support block 115, and abuts the concave portion 128 a when the wheel holder 120 moves toward the support block 115.

階差部128b設於與支持板部116相對面之側之面的下方。階差部128b朝與搖動軸線sc2平行之方向延伸成直線狀。又，支持板部116在與階差部128b相對面之位置形成段部117。另一方面，扣件承接部128c會形成內藏有用以將樹脂製袋128固定於支持板部116之扣件(未圖示)的空間。扣件承接部128c內之空間形成有用以承接螺釘等所構成之扣件頭部的階差。 The step portion 128 b is provided below a surface on the side opposite to the surface of the support plate portion 116. The step portion 128b extends linearly in a direction parallel to the swing axis sc2. Further, the support plate portion 116 forms a step portion 117 at a position facing the step portion 128b. On the other hand, the fastener receiving portion 128 c forms a space in which a fastener (not shown) for fixing the resin bag 128 to the supporting plate portion 116 is formed. The space in the fastener receiving portion 128c forms a step for receiving a fastener head made of a screw or the like.

接著，針對如以上構成而成之本實施形態之車輪保持單元100的作用及效果來說明。 Next, operations and effects of the wheel holding unit 100 of the present embodiment configured as described above will be described.

首先，本實施形態之車輪保持單元100在可相對動作之支持塊體115與車輪保持器120之間，設有因車輪保持器120之對支持塊體115之相對動作而變形的第1彈性構造體125與第2彈性構造體127。該第1彈性構造體125與第2彈性構造體127宜為上述條件a，即，當車輪保持器120相對於支持塊體115的動作開始時，首先，就只有第1彈性構造體125在車輪保持器120與支持塊體115之間來加壓而變 形，當車輪保持器120相對於支持塊體115的動作進而進展時，除了第1彈性構造體125之外，第2彈性構造體127亦在車輪保持器120與支持塊體115之間來加壓而變形。上述嬰兒車10中，在對嬰兒車10之移動負載較小時，例如搭乘嬰兒車之嬰幼兒的月齡較低且在籃部90未放置行李時，利用第1彈性構造體127，可有效地吸收在行走時之振動或衝擊，便可發揮優秀的避震功能。另一方面，對嬰兒車10之移動負載較大時，例如搭乘嬰兒車10之嬰幼兒的月齡較高且在籃部90有放入較重行李時，就利用與第1彈性構造體125不同之第2彈性構造體127，或是，利用第1彈性構造體125與第2彈性構造體127兩方，安定地支持負載並且有效地吸收在行走時之振動或衝擊，便可發揮優秀的避震功能。即，不受到對嬰兒車10之移動負載的大小影響，而可對嬰兒車10賦予優異之搭乘舒適度。 First, the wheel holding unit 100 of this embodiment is provided with a first elastic structure that is deformed by the relative movement of the wheel holder 120 to the support block 115 between the support block 115 and the wheel holder 120 that can move relative to each other. The body 125 and the second elastic structure 127. The first elastic structure 125 and the second elastic structure 127 preferably satisfy the condition a, that is, when the operation of the wheel holder 120 with respect to the support block 115 starts, first, only the first elastic structure 125 is on the wheel. Pressurized between the holder 120 and the support block 115 When the movement of the wheel retainer 120 relative to the support block 115 progresses, in addition to the first elastic structure 125, the second elastic structure 127 is also added between the wheel retainer 120 and the support block 115. Deformed. In the above-mentioned baby carriage 10, when the moving load on the baby carriage 10 is small, for example, when the infants and young children who ride the baby carriage are younger and their luggage is not placed in the basket 90, the first elastic structure 127 is effective. The ground absorbs vibration or shock while walking, and can play an excellent shock-absorbing function. On the other hand, when the moving load on the stroller 10 is large, for example, when the infants and young children who ride the stroller 10 are older and have heavy luggage in the basket 90, the first elastic structure 125 is used. The second elastic structure 127, which is different, or both of the first elastic structure 125 and the second elastic structure 127, can stably support the load and effectively absorb vibration or impact during walking, and can exhibit excellent performance. Suspension function. That is, it is possible to impart excellent riding comfort to the stroller 10 without being affected by the magnitude of the moving load on the stroller 10.

又，第1彈性構造體125與第2彈性構造體127宜為上述條件b，即假設在車輪保持器120與支持塊體115之間只配置第1彈性構造體125時，使第1彈性構造體125變形而使車輪保持器120相對於支持塊體115只動作預定量所需要之力量的大小，會與假設在車輪保持器120與支持塊體115之間只配置第2彈性構造體127時，使第2彈性構造體127變形而使車輪保持器120相對於支持塊體115只動作相同量所需要之力量的大小不同。即，宜為第1彈性構造體125對車輪保持器120與支持塊體115之相對動作的抗力、以及第2彈性構造體127對車輪保持器120與支持塊體115之相對動作的 抗力有所不同。上述嬰兒車10中，在第1彈性構造體125與第2彈性構造體127之間，以材料、構造、配置、可變形量等為不同之方式，來適宜設計第1彈性構造體125與第2彈性構造體127，藉此可用較高之設計自由度，來對車輪保持單元100賦予期望之避震功能。 In addition, the first elastic structure 125 and the second elastic structure 127 should satisfy the above condition b. That is, if only the first elastic structure 125 is arranged between the wheel retainer 120 and the support block 115, the first elastic structure is made. When the body 125 is deformed to make the wheel retainer 120 move a predetermined amount with respect to the support block 115, the amount of force required is the same as when only the second elastic structure 127 is arranged between the wheel retainer 120 and the support block 115. The magnitude of the force required to deform the second elastic structure 127 and cause the wheel retainer 120 to move only the same amount relative to the support block 115 is different. That is, the resistance of the first elastic structure 125 to the relative movement of the wheel retainer 120 and the support block 115 and the relative movement of the second elastic structure 127 to the wheel retainer 120 and the support block 115 are preferable. Resistance is different. In the aforementioned stroller 10, between the first elastic structure 125 and the second elastic structure 127, the first elastic structure 125 and the first elastic structure 125 are appropriately designed in different ways such as material, structure, arrangement, and amount of deformation. The 2 elastic structure 127 can provide a desired shock-absorbing function to the wheel holding unit 100 with a high degree of design freedom.

進而，第1彈性構造體125與第2彈性構造體127亦可滿足上述之條件a與條件b的兩方。作為一例，當第1彈性構造體125對車輪保持器120與支持塊體115之相對動作的抗力變得比第2彈性構造體127對車輪保持器120與支持塊體115之相對動作的抗力更小時，在嬰兒車10之移動負載較小的情形下，就可利用第1彈性構造體125安定地支持負載，並且利用第1彈性構造體125有效地吸收在行走時之振動或衝擊。又，在嬰兒車10之移動負載較大之情形下，可利用第1彈性構造體125，或是，可利用第1彈性構造體125與第2彈性構造體127來更安定地支持負載並且有效地吸收行走時之振動或衝擊。因此，可非常有效地排除對嬰兒車10之移動負載大小的影響，可對嬰兒車10賦予優異之搭乘舒適度。 Furthermore, the first elastic structure 125 and the second elastic structure 127 may satisfy both of the conditions a and b described above. As an example, the resistance of the first elastic structure 125 to the relative movement of the wheel retainer 120 and the support block 115 becomes greater than the resistance of the second elastic structure 127 to the relative movement of the wheel retainer 120 and the support block 115. When the moving load of the stroller 10 is small, the first elastic structure 125 can be used to stably support the load, and the first elastic structure 125 can effectively absorb vibration or impact during walking. When the moving load of the stroller 10 is large, the first elastic structure 125 or the first elastic structure 125 and the second elastic structure 127 can be used to support the load more stably and effectively. Ground to absorb vibration or shock when walking. Therefore, the influence on the magnitude of the moving load of the stroller 10 can be eliminated very effectively, and excellent riding comfort can be imparted to the stroller 10.

又，上述實施形態中，第2彈性構造體127構成為密封氣體之袋128。上述第2彈性構造體127亦可藉由調整袋128之形狀或氣體之充填量，適當校正第2彈性構造體127之抗力，特別是隨著變更之進行而來的抗力變化。藉此，可用較高之設計自由度，對車輪保持單元賦予期望的避震功能。 Moreover, in the said embodiment, the 2nd elastic structure 127 was comprised as the gas-tight bag 128. The above-mentioned second elastic structure 127 may also adjust the resistance of the second elastic structure 127 by adjusting the shape of the bag 128 or the filling amount of the gas, and in particular, the resistance changes as the change proceeds. Thereby, a high degree of design freedom can be used to impart a desired shock-absorbing function to the wheel holding unit.

進而，上述實施形態中，成為第2彈性構造體127之袋128形成有延伸成直線狀的凹部128a。且，車輪保持器120與支持塊體115之其中一方會以凹部128a與車輪保持器120相對於支持塊體115之搖動軸線sc2正交並延伸的方式支持袋128，車輪保持器120與支持塊體115之另一方則具有：在車輪保持器120與支持塊體115之相對動作時將位於凹部128a內的凸部123。因第2彈性構造體127是密封氣體之袋128，可朝各種方向變形，但藉由凹部128a與凸部123之卡合，可變形之第2彈性構造體127會與車輪保持器120及支持塊體115另一方維持預定的位置關係，袋128便會進行預定之變形。藉此，便可確保期待之避震效果。又，車輪保持器120相對於支持塊體115之動作開始前，即使可變形之第2彈性構造體127與車輪保持器120及支持塊體115的另一方為非接觸且可變形之第2彈性構造體127與車輪保持器及支持塊體的另一方並未直接地連接，亦可藉由凹部128a與凸部123之卡合，使可變形之第2彈性構造體127與車輪保持器120及支持塊體115的另一方維持預定的位置關係，可安定地確保期待的避震效果。 Furthermore, in the above-mentioned embodiment, the pocket 128 serving as the second elastic structure 127 is formed with a recessed portion 128 a extending linearly. In addition, one of the wheel retainer 120 and the support block 115 supports the pocket 128 in such a manner that the recess 128a and the swing axis sc2 of the wheel retainer 120 relative to the support block 115 extend orthogonally and extend, and the wheel retainer 120 and the support block 115 The other side of the body 115 includes a convex portion 123 that will be located in the concave portion 128 a when the wheel retainer 120 and the support block 115 are relatively moved. The second elastic structure 127 is a gas-sealed bag 128 and can be deformed in various directions. However, the second elastic structure 127 is deformable with the wheel retainer 120 and the support by engaging the concave portion 128a and the convex portion 123. The other side of the block 115 maintains a predetermined positional relationship, and the bag 128 undergoes a predetermined deformation. This will ensure the desired shock absorption effect. Before the operation of the wheel retainer 120 with respect to the support block 115 is started, even if the second elastic structure 127 that is deformable and the other of the wheel retainer 120 and the support block 115 are non-contact and deformable second elasticity The structure body 127 is not directly connected to the other of the wheel retainer and the support block, and the second elastic structure body 127 and the wheel retainer 120 and the deformable second elastic structure 127 can also be engaged with each other by engaging the concave portion 128a with the convex portion 123. The other side of the support block 115 maintains a predetermined positional relationship, and can securely secure a desired shock-absorbing effect.

進而，上述實施形態中，藉由階差部128b與段部117之卡合，可限制支持塊體115之支持板部116上之袋128的偏移，且，亦可抑制朝未預期之方向之樹脂製袋128的變形。藉此，袋128所構成之第2彈性構造體127便可發揮所期待之避震效果。進而，上述實施形態中，在成為第2彈性構造體127之袋128形成有具有階差(突緣)部之扣件承接部 128c。利用該扣件承接部128c，袋128便可保持在不易變形之方向，藉此，在車輪保持器120與支持塊體115之相對動作時，袋128之變形會大致固定，並表現出期待之預定的避震功能。 Furthermore, in the above-mentioned embodiment, the engagement of the step portion 128b and the segment portion 117 can limit the shift of the bag 128 on the support plate portion 116 of the support block 115, and can also suppress the unexpected direction The resin bag 128 is deformed. Thereby, the second elastic structure 127 constituted by the bag 128 can exhibit a desired shock-absorbing effect. Furthermore, in the above-mentioned embodiment, the bag receiving portion 128 serving as the second elastic structure 127 is formed with a fastener receiving portion having a stepped (flange) portion. 128c. By using the fastener receiving portion 128c, the bag 128 can be kept in a direction that is not easily deformed. As a result, when the relative movement of the wheel holder 120 and the support block 115 is performed, the deformation of the bag 128 is substantially fixed, and the expected performance is shown. Scheduled suspension.

又，在第2彈性構造體127作為密封氣體之袋128而構成的情形下，在車輪保持器120對支持塊體110動作時，車輪保持器120與支持塊體110其中一方宜從形成於袋128之角部開始朝該袋128接觸。密封氣體之袋128所構成之第2彈性構造體127顯示袋128之角部對於變形之優異耐受性，另一方面，在角部開始變形之後，便可柔軟地變形而敏感地吸收車輪保持器120相對於支持塊體110的動作。因此，可用第2彈性構造體127安定地支持對嬰兒車10所預想之移動負載，進而，支持移動負載之第2彈性構造體127可發揮有效地吸收衝擊或振動的避震功能。 In the case where the second elastic structure 127 is configured as the gas-sealed bag 128, when the wheel retainer 120 operates on the support block 110, one of the wheel retainer 120 and the support block 110 should be formed from the bag. The corners of 128 begin to contact the bag 128. The second elastic structure 127 formed by the gas-sealed bag 128 shows the excellent resistance of the corner portion of the bag 128 to deformation. On the other hand, after the corner portion begins to deform, it can be softly deformed and sensitively absorb the wheel retention The motion of the device 120 relative to the support block 110. Therefore, the second elastic structure 127 can stably support the moving load expected for the stroller 10, and the second elastic structure 127 supporting the moving load can exhibit a shock-absorbing function that effectively absorbs shock or vibration.

而，彈性構造體125、127中，不限於是密封氣體之袋128的情形，亦可使彈性構造體125、127對車輪保持器120與支持塊體115之相對動作之抗力在彈性構造體125、127之變形開始後，並非固定而會變動。即使是在上述例中，藉由適宜地設定彈性構造體125、127對車輪保持器120與支持塊體115之相對動作之抗力，便可不受到嬰兒車10之移動負載的大小影響，而對嬰兒車10賦予優異之搭乘舒適度。 In addition, the elastic structures 125 and 127 are not limited to the case of sealing the gas bag 128, and the resistance of the elastic structures 125 and 127 to the relative movements of the wheel retainer 120 and the support block 115 to the elastic structure 125 can be made. After the deformation of 127 starts, it is not fixed but will change. Even in the above-mentioned example, by appropriately setting the resistance of the elastic structures 125 and 127 to the relative movement of the wheel retainer 120 and the support block 115, it is possible not to be affected by the magnitude of the moving load of the stroller 10, but to the baby The car 10 imparts excellent ride comfort.

進而，彈性構造體125、127之至少一者以上露出時，視覺上可聯想到避震功能，便可給予嬰幼兒之保護者 安心感。特別是，密封氣體之袋128所構成之第2彈性構造體127可強烈地聯想到避震功能，特別是袋128為透明或半透明時，可更加強烈地聯想到避震功能。 Furthermore, when at least one of the elastic structures 125 and 127 is exposed, a shock-absorbing function can be visually associated, and a protector for infants can be provided. Peace of mind. Particularly, the second elastic structure 127 formed by the gas-sealed bag 128 can strongly associate with the shock-absorbing function, and particularly when the bag 128 is transparent or translucent, it can strongly associate with the shock-absorbing function.

而，本實施形態中，車輪保持單元100構造成為腳輪，旋轉體110相對於固定體105而可旋轉，但並不限於此。即使是對於旋轉體110與固定體105可相對旋轉、即車輪101不可回旋的車輪保持單元，亦可適用於第1切換構件75與第2切換構件80，且，可獲得第1切換構件75與第2切換構件80帶來的上述作用效果。又，本實施形態中，顯示了車輪保持單元100具有第1切換構件75與第2切換構件80兩方的範例，但不限於此。車輪保持單元100亦可只具有第2切換構件80，在該例中，便可獲得只有第2切換構件80帶來的上述作用效果。 However, in the present embodiment, the wheel holding unit 100 is configured as a caster, and the rotating body 110 is rotatable relative to the fixed body 105, but it is not limited to this. Even if the wheel holding unit is capable of relatively rotating the rotating body 110 and the fixed body 105, that is, the wheel 101 cannot be rotated, it can be applied to the first switching member 75 and the second switching member 80, and the first switching member 75 and the second switching member 75 and The above-mentioned operational effects provided by the second switching member 80. In this embodiment, an example in which the wheel holding unit 100 includes both the first switching member 75 and the second switching member 80 is shown, but the invention is not limited thereto. The wheel holding unit 100 may include only the second switching member 80, and in this example, the above-mentioned effect provided by only the second switching member 80 can be obtained.

<<切換機構>> << Switching mechanism >>

接著，針對切換機構88來說明。 Next, the switching mechanism 88 will be described.

<切換機構之整體構成> <Overall Structure of Switching Mechanism>

如上所述，切換機構88是根據把手70之位置而自動地切換車輪保持單元100之旋轉體110相對於固定體105可旋轉之狀態與不可旋轉之狀態的機構。特別是本實施形態中，前腳20與後腳21全都設有構造成為腳輪之車輪保持單元100，又切換機構88會根據把手70之位置，使安裝於位在進行方向前方側之腳之車輪保持單元100的旋轉體110相對於固定體105以腳輪軸線Ac為中心的旋轉為可能，且，限制安裝於位在進行方向後方側之腳之車輪保持單元100之旋 轉體110相對於固定體105以腳輪軸線Ac為中心的旋轉。更具體而言，切換機構88以把手70配置於圖1、圖3、圖5所示之第1位置(背面推壓位置)的狀態，使安裝於前腳20之車輪保持單元100之旋轉體110相對於固定體105的旋轉為可能，並且限制安裝於後腳21之車輪保持單元100之旋轉體110相對於固定體105的旋轉。另一方面，切換機構88以把手70配置於圖2、圖4、圖6所示之第2位置(相對面推壓位置)的狀態，限制安裝於前腳20之車輪保持單元100之旋轉體110相對於固定體105的旋轉，並且使安裝於後腳21之車輪保持單元100之旋轉體110相對於固定體105的旋轉為可能。 As described above, the switching mechanism 88 is a mechanism that automatically switches the state in which the rotating body 110 of the wheel holding unit 100 is rotatable relative to the fixed body 105 in accordance with the position of the handle 70. In particular, in this embodiment, both the front foot 20 and the rear foot 21 are provided with a wheel holding unit 100 configured as a caster, and the switching mechanism 88 will install the wheel holding unit on the foot on the front side in the forward direction according to the position of the handle 70. The rotation of the rotating body 110 of 100 with respect to the fixed body 105 centered on the caster axis Ac is possible, and the rotation of the wheel holding unit 100 mounted on the foot on the rear side in the progress direction is restricted. The rotating body 110 rotates about the caster axis Ac as a center with respect to the fixed body 105. More specifically, the switching mechanism 88 causes the rotating body 110 of the wheel holding unit 100 attached to the front foot 20 to be in a state where the handle 70 is disposed at the first position (rear pressing position) shown in FIGS. 1, 3, and 5. The rotation with respect to the fixed body 105 is possible, and the rotation of the rotating body 110 of the wheel holding unit 100 mounted on the rear leg 21 with respect to the fixed body 105 is restricted. On the other hand, the switching mechanism 88 restricts the rotating body 110 of the wheel holding unit 100 attached to the front foot 20 in a state where the handle 70 is disposed at the second position (opposite surface pressing position) shown in FIGS. 2, 4, and 6. The rotation with respect to the fixed body 105 and the rotation of the rotating body 110 of the wheel holding unit 100 mounted on the rear leg 21 with respect to the fixed body 105 are possible.

切換機構88具有：設於把手70且隨著把手70之搖動而可動作之第1切換構件75、支持於後腳21且隨著第1切換構件75之動作而可動作之第2切換構件80、設於車輪保持單元100之鎖定構件130、及將第2切換構件80之動作朝鎖定構件130傳達的傳達器件87。 The switching mechanism 88 includes a first switching member 75 provided on the handle 70 and operable as the handle 70 swings, a second switching member 80 supported on the rear foot 21 and operable as the first switching member 75 operates, A lock member 130 provided in the wheel holding unit 100 and a transmission device 87 that transmits the operation of the second switching member 80 to the lock member 130.

當中，如上所述，第1切換構件75會構成把手70之一部分。因此，第1切換構件75在把手70搖動於圖1、圖3、圖5所示之第1位置與在圖2、圖4、圖6所示之第2位置之間時，以把手70之搖動軸線為中心而動作，即進行旋轉運動或旋繞運動。而，本實施形態中，把手70之搖動軸線da會與將把手70支持成可搖動之軸構件13的軸線方向da一致。又本實施形態中，如圖11~14所示，由於軸構件13亦貫通第1切換構件75，因此第1切換構件75隨著把手70之搖動，以把手70之搖動軸線da為中心而旋動。第2切換構件80會配置 於比第1切換構件75更上方之後腳21上的位置。第2切換構件80可滑動於後腳21上。 Among them, as described above, the first switching member 75 constitutes a part of the handle 70. Therefore, when the first switching member 75 is shaken between the first position shown in FIG. 1, FIG. 3, and FIG. 5 and the second position shown in FIG. 2, FIG. 4, and FIG. The shaking axis acts as the center, that is, it performs a rotating motion or a winding motion. However, in this embodiment, the pivoting axis da of the handle 70 coincides with the axial direction da of the shaft member 13 that supports the pivotable shaft member 13. In this embodiment, as shown in FIGS. 11 to 14, since the shaft member 13 also penetrates the first switching member 75, the first switching member 75 rotates with the swing of the handle 70 and rotates around the swing axis da of the handle 70. move. The second switching member 80 is arranged A position on the foot 21 after being higher than the first switching member 75. The second switching member 80 is slidable on the rear leg 21.

第1切換構件75具有：隨著把手70之搖動而動作時，與第2切換構件80抵接之凸輪抵接面76。另一方面，第2切換構件80具有承接凸輪抵接面76的凸輪承接片81。本實施形態中，不只是重力，賦予勢能構件85會內藏於例如後腳21內(參照圖19)，並透過後述中繼構件83，使第2切換構件80沿著後腳21朝下方來賦予勢能。利用來自賦予勢能構件85的勢能，第2切換構件80之凸輪承接片81與第1切換構件75之凸輪抵接面76便可維持於抵接之狀態。且，本實施形態中，隨著把手70之搖動，凸輪抵接面76當中之與凸輪承接片81抵接的位置會變化，藉此對抗賦予勢能構件85之賦予勢能力，第2切換構件80便滑動於後腳21上。 The first switching member 75 includes a cam contact surface 76 that comes into contact with the second switching member 80 when the handle 70 is moved in response to the swing of the handle 70. On the other hand, the second switching member 80 includes a cam receiving piece 81 that receives the cam contact surface 76. In this embodiment, not only gravity, but the potential energy imparting member 85 is built in, for example, the rear leg 21 (see FIG. 19), and the second switching member 80 is directed downward along the rear leg 21 through the relay member 83 described later to impart potential energy. . By using the potential energy from the potential energy imparting member 85, the cam receiving piece 81 of the second switching member 80 and the cam abutting surface 76 of the first switching member 75 can be maintained in a contact state. Further, in this embodiment, as the handle 70 is shaken, the position of the cam contact surface 76 that abuts against the cam receiving piece 81 changes, thereby counteracting the potential imparting ability of the potential imparting member 85, and the second switching member 80 It slides on the hind feet 21.

如圖17~19所示，本實施形態中，隨著把手70從第1位置朝向第2位置，凸輪抵接面76當中與凸輪承接片81抵接的部位在嬰兒車10之側面視點下，會從搖動軸線da逐漸分開。故，使把手70從第1位置朝第2位置來搖動時，第2切換構件80將會朝向上方而滑動於後腳21上。相反地，使把手70從第2位置朝第1位置搖動時，第2切換構件80會朝向下方而滑動於後腳21上。 As shown in FIGS. 17 to 19, in this embodiment, as the handle 70 moves from the first position to the second position, the portion of the cam contact surface 76 that abuts against the cam receiving piece 81 is under the side view of the stroller 10. Will gradually separate from the shaking axis da. Therefore, when the handle 70 is shaken from the first position to the second position, the second switching member 80 slides on the rear leg 21 upward. Conversely, when the handle 70 is shaken from the second position to the first position, the second switching member 80 slides on the rear leg 21 downward.

而，第1切換構件75之凸輪抵接面76及第2切換構件80之凸輪承接片81設計成主要用以使第1切換構件75小型化。針對第1切換構件75之凸輪抵接面76與第2切換構件80之凸輪承接片81會於後詳述。 In addition, the cam abutting surface 76 of the first switching member 75 and the cam receiving piece 81 of the second switching member 80 are designed mainly to miniaturize the first switching member 75. The cam contact surface 76 of the first switching member 75 and the cam receiving piece 81 of the second switching member 80 will be described in detail later.

隨著第2切換構件80之滑動而動作的鎖定構件130設於車輪保持單元100。如上所述，車輪保持單元100具有：車輪101、將車輪101支持成可旋轉之旋轉體旋轉體110、及安裝於前腳20與後腳21當中之至少一方且以腳輪軸線Ac為中心而將旋轉體110支持成可旋轉的固定體105。進而，如圖25與圖26所示，鎖定構件130可移動於：限制旋轉體110相對於固定體105旋轉的圖26的鎖定位置、與可使旋轉體110相對於固定體105旋轉之圖25的鎖定解除位置之間。因此，本實施形態之切換機構88根據把手70相對於嬰兒車本體11的搖動，使鎖定構件130從鎖定解除位置朝鎖定位置或從鎖定位置朝鎖定解除位置來移動。 A lock member 130 that operates in accordance with the sliding of the second switching member 80 is provided in the wheel holding unit 100. As described above, the wheel holding unit 100 includes a wheel 101, a rotating body rotating body 110 supporting the wheel 101 to be rotatable, and a rotating body mounted on at least one of the front foot 20 and the rear foot 21 with the caster axis Ac as a center. 110 is supported as a rotatable fixed body 105. Further, as shown in FIGS. 25 and 26, the locking member 130 can be moved to a locked position of FIG. 26 that restricts the rotation of the rotating body 110 relative to the fixed body 105, and FIG. 25 that allows the rotating body 110 to rotate relative to the fixed body 105. Between the unlocked position. Therefore, the switching mechanism 88 of this embodiment moves the lock member 130 from the unlocked position to the locked position or from the locked position to the unlocked position according to the swing of the handle 70 relative to the stroller body 11.

而，鎖定構件130設計成用以使其動作安定。且，針對鎖定構件130以及保持鎖定構件130之車輪保持單元100的構造於後詳述。 In addition, the lock member 130 is designed to stabilize its operation. The structure of the lock member 130 and the wheel holding unit 100 holding the lock member 130 will be described in detail later.

接著針對傳達器件87來說明。傳達器件87設於第2切換構件80與車輪保持單元100之間，並構造成將第2切換構件80之滑動動作朝車輪保持單元100之鎖定構件130傳達，藉此，使鎖定構件130在鎖定位置與鎖定解除位置之間動作。本實施形態中，後腳21內設有中繼構件83。且，中繼構件83與第2切換構件80連接，並與第2切換構件80相對於後腳21的滑動同步地在後腳21內上下移動。傳達器件87具有：其中一端安裝於中繼構件83且另一端安裝於鎖定構件130的線材87b、與線材87b貫通其內部並延伸的筒狀構件87a。如圖19所示，筒狀構件87a之其中一端保持於設於後 腳21內之中繼構件83附近位置的保持部84，如圖25與圖26所示，筒狀構件87a之另一端則保持於設於車輪保持單元100之鎖定構件130附近位置的保持部107。該結果，當第2切換構件80相對於後腳21滑動時，線材87b便會移動於筒狀構件87a內，與線材87b之另一端連接之鎖定構件130便會隨著線材87b之動作移動。 Next, the transmission device 87 will be described. The transmitting device 87 is provided between the second switching member 80 and the wheel holding unit 100, and is configured to transmit the sliding action of the second switching member 80 to the locking member 130 of the wheel holding unit 100, thereby causing the locking member 130 to lock. Operates between the position and the unlocked position. In this embodiment, a relay member 83 is provided in the rear leg 21. The relay member 83 is connected to the second switching member 80 and moves up and down in the rear foot 21 in synchronization with the sliding of the second switching member 80 relative to the rear foot 21. The transmission device 87 includes a wire 87b with one end attached to the relay member 83 and the other end attached to the lock member 130, and a cylindrical member 87a extending through the wire 87b and extending through the inside. As shown in FIG. 19, one end of the cylindrical member 87a is held behind As shown in FIGS. 25 and 26, the holding portion 84 near the relay member 83 in the leg 21 is held at the holding portion 107 provided near the lock member 130 of the wheel holding unit 100 at the other end. . As a result, when the second switching member 80 slides relative to the rear leg 21, the wire 87b moves inside the cylindrical member 87a, and the lock member 130 connected to the other end of the wire 87b moves with the movement of the wire 87b.

而，本實施形態中，如上所述，前腳20與後腳21均安裝有：具有作為腳輪之功能的車輪保持單元100。因此，如圖5所示，中繼構件83與前腳用之車輪保持單元100之間設有一個傳達器件87，在中繼構件83與後腳用之車輪保持單元100之間設有另外一個的傳達器件87。又，如上所述，本實施形態之嬰兒車10大致上以在寬度方向中心朝前後方向延伸之面為中心而構造成左右對稱。故，成為切換機構88之第1切換構件75、第2切換構件80及中繼構件83、前腳用之傳達器件87、前腳用之車輪保持單元100、後腳用之傳達器件87、以及後腳用之車輪保持單元100都會設於左右方。 In this embodiment, as described above, the front foot 20 and the rear foot 21 are each provided with a wheel holding unit 100 having a function as a caster. Therefore, as shown in FIG. 5, a transmission device 87 is provided between the relay member 83 and the wheel holding unit 100 for the front foot, and another transmission is provided between the relay member 83 and the wheel holding unit 100 for the rear foot. Device 87. As described above, the baby carriage 10 according to the present embodiment is configured to be bilaterally symmetrical about a surface extending substantially in the center of the width direction toward the front-rear direction. Therefore, the first switching member 75, the second switching member 80, and the relay member 83 of the switching mechanism 88, the front foot transmission device 87, the front foot wheel holding unit 100, the rear foot transmission device 87, and the rear foot transmission device. Both the wheel holding units 100 are provided on the left and right sides.

<第1切換構件之凸輪抵接面與第2切換構件之凸輪承接片> <The cam contact surface of the first switching member and the cam receiving piece of the second switching member>

在此，主要參照圖16~圖21，並且針對第1切換構件75之凸輪抵接面76與第2切換構件80之凸輪承接片81來進而詳述。 Here, referring mainly to FIGS. 16 to 21, the cam contact surface 76 of the first switching member 75 and the cam receiving piece 81 of the second switching member 80 will be further described in detail.

如上所述，隨著把手70之搖動，凸輪抵接面76當中與凸輪承接片81抵接之位置有所變化，藉此，利用賦 予勢能構件85朝向第1切換構件75推壓之第2切換構件80便會滑動於後腳21上。如圖17~19所示，本實施形態中，隨著把手70從第1位置朝向第2位置，凸輪抵接面76當中與凸輪承接片81抵接的部位在嬰兒車10之側面視點下，會從搖動軸線da逐漸分開。故，使把手70從第1位置朝第2位置搖動時，第2切換構件80會朝向上方來滑動於後腳21上。相反地，使把手70從第2位置朝第1位置搖動時，第2切換構件80會朝向下方來滑動於後腳21上。 As described above, as the handle 70 swings, the position of the cam abutting surface 76 that abuts against the cam receiving piece 81 changes. The second switching member 80 pushed by the pre-potential energy member 85 toward the first switching member 75 slides on the rear foot 21. As shown in FIGS. 17 to 19, in this embodiment, as the handle 70 moves from the first position to the second position, the portion of the cam contact surface 76 that abuts against the cam receiving piece 81 is under the side view of the stroller 10. Will gradually separate from the shaking axis da. Therefore, when the handle 70 is shaken from the first position to the second position, the second switching member 80 slides on the rear leg 21 upward. Conversely, when the handle 70 is shaken from the second position to the first position, the second switching member 80 slides on the rear foot 21 downward.

又，本實施形態中，凸輪承接片81當中與凸輪抵接面76接觸的位置亦隨著把手70之搖動而變化。如圖17~圖21所示，把手70相對於嬰兒車本體11朝固定方向來搖動時，凸輪承接片81當中與凸輪抵接面76接觸的位置會從凸輪抵接面76之移動路徑之上游側往下游側來變化。亦即是，凸輪承接片81當中與凸輪抵接面76接觸的位置會與和把手70一起動作之凸輪抵接面76朝相同的固定方向來移動。根據上述本實施形態，如圖17所示，在把手70配置於第1位置之狀態下，可令第1切換構件75之凸輪抵接面76配置於只與在把手70從第1位置朝第2位置搖動的期間接觸到的第2切換構件80之凸輪承接片81的部位當中的一部分相對面的位置，且，如圖21所示，在把手70配置於第2位置之狀態下，可令凸輪抵接面76配置於只與在把手70從第1位置朝第2位置搖動的期間接觸到的凸輪承接片81的部位當中的一部分相對面的位置。 In addition, in this embodiment, the position of the cam receiving piece 81 in contact with the cam abutting surface 76 also changes in accordance with the swing of the handle 70. As shown in FIGS. 17 to 21, when the handle 70 is swung in a fixed direction relative to the stroller body 11, the position of the cam receiving piece 81 that is in contact with the cam abutting surface 76 is upstream from the moving path of the cam abutting surface 76. Side to side. That is, the position of the cam receiving piece 81 that is in contact with the cam abutting surface 76 is moved in the same fixed direction as the cam abutting surface 76 that moves together with the handle 70. According to the present embodiment described above, as shown in FIG. 17, in a state where the handle 70 is disposed at the first position, the cam contact surface 76 of the first switching member 75 can be disposed only with the handle 70 from the first position toward the first position. The position of a portion of the cam receiving piece 81 of the second switching member 80 that is in contact with the cam receiving piece 81 during the two-position shaking position is opposite to the position. As shown in FIG. 21, in a state where the handle 70 is disposed at the second position, The cam abutting surface 76 is disposed at a position facing only a part of the portion of the cam receiving piece 81 that comes into contact with the handle 70 while the handle 70 is swung from the first position to the second position.

即，凸輪承接片81當中與凸輪抵接面76接觸的位 置沒有變化時，例如，使第1切換構件75更具有圖21中二點鏈線所示之部分，便需要將第1切換構件75之凸輪抵接面76製作得更長。因此，根據本實施形態，便可將容易複雜化之切換機構88的第1切換構件75小型輕量化，以結果而論，便可實現嬰兒車10之小型輕量化。特別是把手70之搖動軸線da的附近會配置與嬰兒車10之折疊動作、或布片支持單元40及布片150之傾斜動作等相關連的構成，空間上的空缺較少。實際上如圖12所示，第1切換構件75之正後方設有狀態維持機構35之操作構件35b。所圖示之例中，與該操作構件35b之干涉會產生，故，實質上無法設置圖21中二點鏈線所示的延長部分。即，本實施形態之凸輪抵接面76與凸輪承接片81之構成不只是嬰兒車10之小型化且輕量，亦可使嬰兒車10之整體的設計自由度提升。 That is, the position of the cam receiving piece 81 that is in contact with the cam contact surface 76 When the setting is not changed, for example, to make the first switching member 75 more have a portion shown by a two-dot chain line in FIG. 21, it is necessary to make the cam contact surface 76 of the first switching member 75 longer. Therefore, according to this embodiment, the first switching member 75 of the switching mechanism 88 which is easily complicated can be reduced in size and weight, and as a result, the size and weight of the stroller 10 can be reduced. In particular, a structure related to the folding operation of the stroller 10 or the tilting operation of the fabric support unit 40 and the fabric 150 is arranged near the swing axis da of the handle 70, and there is less space in the space. Actually, as shown in FIG. 12, an operation member 35 b of the state maintaining mechanism 35 is provided directly behind the first switching member 75. In the example shown in the figure, interference with the operation member 35b occurs, and therefore, an extension portion indicated by a two-dot chain line in FIG. 21 cannot be provided substantially. That is, the configuration of the cam abutting surface 76 and the cam receiving piece 81 of this embodiment is not only downsizing and lightweight of the stroller 10, but also improves the overall design freedom of the stroller 10.

作為上述構成之具體例，第2切換構件80之凸輪承接片81是與凸輪抵接面76相同地可利用面，更具體而言，利用曲面、平面、折面等來構成。另一方面，如所圖示之例，第2切換構件80之凸輪承接片81亦可具有：朝向第1切換構件75之凸輪抵接面76而突出之至少二個凸輪承接突出部82a、82b。該凸輪承接突出部82a、82b會配置於沿著伴隨把手70搖動之凸輪抵接面76之移動路徑而分開的位置，根據把手70之搖動位置，與凸輪抵接面76接觸之凸輪承接突出部82a、82b便可變化。具有凸輪承接突出部82a、82b之凸輪承接片81的設計與製作並非在凸輪承接片81之整體，而是只在凸輪承接突出部82a、82b之位置才會要求 較高的精度。因此，便可容易地進行凸輪承接片81之製作。 As a specific example of the above configuration, the cam receiving piece 81 of the second switching member 80 is a usable surface similar to the cam contact surface 76, and more specifically, is configured by a curved surface, a flat surface, a folded surface, or the like. On the other hand, as the illustrated example, the cam receiving piece 81 of the second switching member 80 may have at least two cam receiving protrusions 82a, 82b protruding toward the cam contact surface 76 of the first switching member 75. . The cam receiving projections 82 a and 82 b are arranged at positions separated along the moving path of the cam contact surface 76 accompanying the swing of the handle 70, and the cam receiving projections contacting the cam contact surface 76 according to the swing position of the handle 70. 82a, 82b can be changed. The design and manufacture of the cam receiving piece 81 with the cam receiving protrusions 82a, 82b is not the entire cam receiving piece 81, but it is required only at the positions of the cam receiving protrusions 82a, 82b. Higher accuracy. Therefore, the cam receiving piece 81 can be easily manufactured.

而，所圖示之例中，凸輪承接突出部82a、82b是由延伸成線狀之單一凸輪承接片81來形成，但凸輪承接突出部82a、82b亦可分離地來設置。 In the illustrated example, the cam receiving projections 82 a and 82 b are formed by a single cam receiving piece 81 extending in a linear shape, but the cam receiving projections 82 a and 82 b may be provided separately.

又，把手70配置於第1位置與第2位置之間的某一位置時，凸輪抵接面76宜與沿著該凸輪抵接面76之移動路徑相鄰之二個凸輪承接突出部82a、82b同時地接觸。如上所述，本實施形態中，第2切換構件80利用賦予勢能構件85而朝向第1切換構件75來賦予勢能。另一方面，凸輪承接片81當中與凸輪抵接面76接觸的凸輪承接突出部82a、82b會隨著與把手70一起動作之凸輪抵接面76之往固定方向的移動而有所變化。因此，藉由設有凸輪抵接面76與相鄰之二個凸輪承接突出部82a、82b同時地接觸的時點，在與凸輪抵接面76接觸之凸輪承接突出部82a、82b變動時，可避免第1切換構件75與第2切換構件80因賦予勢能構件85而碰撞的情形。又，把手70在可搖動範圍內朝其中一方向搖動與朝另一方向搖動時，即，把手70從第1位置朝向第2位置時與從第2位置朝向第1位置時，均不會產生凸輪承接突出部82a、82b往凸輪抵接面76碰撞所帶來的衝擊、或凸輪承接突出部82a、82b與凸輪抵接面76之端部76a、76b接觸且越過所帶來的衝擊，可確保把手70順利的搖動動作。 When the handle 70 is disposed at a position between the first position and the second position, the cam abutting surface 76 and the two cam receiving protrusions 82a, adjacent to each other along the moving path of the cam abutting surface 76, are preferably used. 82b contacts simultaneously. As described above, in this embodiment, the second switching member 80 applies potential energy toward the first switching member 75 by using the potential imparting member 85. On the other hand, the cam receiving protrusions 82 a and 82 b of the cam receiving piece 81 that are in contact with the cam abutting surface 76 change as the cam abutting surface 76 that moves with the handle 70 moves in a fixed direction. Therefore, when the cam contact surface 76 is provided to simultaneously contact two adjacent cam receiving projections 82a and 82b, the cam receiving projections 82a and 82b in contact with the cam contact surface 76 may be changed when the cam receiving projections 82a and 82b are in contact with each other. A situation where the first switching member 75 and the second switching member 80 collide due to the potential energy supplying member 85 is avoided. In addition, when the handle 70 is shaken in one direction and the other direction within the swingable range, that is, when the handle 70 is moved from the first position to the second position and when the handle 70 is moved from the second position to the first position, The impact caused by the cam receiving projections 82a and 82b colliding with the cam abutting surface 76, or the cam receiving projections 82a and 82b coming in contact with the end portions 76a and 76b of the cam abutting surface 76 and overcoming the impact may be Ensure that the handle 70 is smoothly shaken.

特別是所圖示之本實施形態中，第2切換構件80之凸輪承接片81具有：二個凸輪承接突出部82a、82b，而該二個凸輪承接突出部82a、82b是在把手70從第1位置朝向 第2位置移動時，位於凸輪抵接面76之移動路徑之上游側的第1凸輪承接突出部82a與位於下游側的第2凸輪承接突出部82b。且，在圖17所示之把手70配置於第1位置之狀態下，凸輪抵接面76會在第1凸輪承接突出部82a及第2凸輪承接突出部82b當中只與第1凸輪承接突出部82a相對面且與第1凸輪承接突出部82a接觸。又，在圖21所示之把手70配置於第2位置之狀態下，凸輪抵接面76會在第1凸輪承接突出部82a及第2凸輪承接突出部82b當中只與第2凸輪承接突出部82b相對面且與第2凸輪承接突出部82b接觸。根據上述本實施形態，由於凸輪承接片81之與凸輪抵接面76接觸的位置會跟隨凸輪抵接面76之移動而變化，因此便可使凸輪抵接面76之長度變短。即，可將容易複雜化之切換機構88之第1切換構件75小型輕量化，以結果而論，便可實現嬰兒車10之小型化且輕量。總之，如上所述，本實施形態之凸輪抵接面76與凸輪承接片81之構成可使嬰兒車10整體的設計自由度提升。 In particular, in the illustrated embodiment, the cam receiving piece 81 of the second switching member 80 includes two cam receiving projections 82a and 82b, and the two cam receiving projections 82a and 82b are formed from the handle 70 1 position facing When the second position is moved, the first cam receiving projection 82a located on the upstream side of the moving path of the cam contact surface 76 and the second cam receiving projection 82b located on the downstream side. In addition, in a state where the handle 70 shown in FIG. 17 is disposed at the first position, the cam abutting surface 76 is only the first cam receiving protrusion among the first cam receiving protrusion 82a and the second cam receiving protrusion 82b. 82a is opposed to and is in contact with the first cam receiving protrusion 82a. In the state where the handle 70 shown in FIG. 21 is disposed at the second position, the cam abutting surface 76 is only the second cam receiving protrusion among the first cam receiving protrusion 82a and the second cam receiving protrusion 82b. 82b is opposed to and is in contact with the second cam receiving protrusion 82b. According to the present embodiment described above, since the position of the cam receiving piece 81 in contact with the cam contact surface 76 changes according to the movement of the cam contact surface 76, the length of the cam contact surface 76 can be shortened. That is, the first switching member 75 of the switching mechanism 88 which is easily complicated can be reduced in size and weight, and as a result, the stroller 10 can be reduced in size and weight. In short, as described above, the configuration of the cam abutting surface 76 and the cam receiving piece 81 of this embodiment can improve the design freedom of the entire stroller 10.

進而，根據本實施形態，把手70配置於位於圖17之第1位置與圖21之第2位置之間之圖18所示的第1中間位置時，凸輪抵接面76會與第1凸輪承接突出部82a及第2凸輪承接突出部86b之兩方相對面且只與第1凸輪承接突出部82a接觸。另一方面，把手配置於位於圖18之第1中間位置與圖21之第2位置之間之圖20所示的第2中間位置時，凸輪抵接面76會與第1凸輪承接突出部82a及第2凸輪承接突出部82b之兩方相對面且只與第2凸輪承接突出部82b接觸。根 據上述本實施形態，可設有凸輪抵接面76與相鄰之二個凸輪承接突出部82a、82b同時地接觸的時點。即，把手70配置於位於圖18之第1中間位置與圖20之第2中間位置之間之圖19所示的位置時，凸輪抵接面76可與第1凸輪承接突出部82a及第2凸輪承接突出部82b之兩方接觸。根據上述本實施形態，如上所述，與凸輪抵接面76接觸之凸輪承接突出部82a、82b變動時，不會產生凸輪承接突出部82a、82b往凸輪抵接面76碰撞所帶來的衝擊、或凸輪承接突出部82a、82b與凸輪抵接面76之端部76a、76b接觸且越過所帶來的衝擊，可確保把手70之順利的搖動動作。 Furthermore, according to this embodiment, when the handle 70 is disposed in the first intermediate position shown in FIG. 18 between the first position in FIG. 17 and the second position in FIG. 21, the cam contact surface 76 receives the first cam. The two opposing surfaces of the protruding portion 82a and the second cam receiving protruding portion 86b are in contact with only the first cam receiving protruding portion 82a. On the other hand, when the handle is disposed at the second intermediate position shown in FIG. 20 between the first intermediate position in FIG. 18 and the second intermediate position in FIG. 21, the cam abutting surface 76 and the first cam receiving protrusion 82 a The two opposing surfaces of the second cam receiving protrusion 82b and the second cam receiving protrusion 82b are in contact with only the second cam receiving protrusion 82b. root According to the present embodiment described above, it is possible to provide a point in time when the cam abutting surface 76 and two adjacent cam receiving projections 82a and 82b are simultaneously contacted. That is, when the handle 70 is disposed at the position shown in FIG. 19 between the first intermediate position in FIG. 18 and the second intermediate position in FIG. 20, the cam contact surface 76 may be in contact with the first cam receiving projection 82 a and the second Both sides of the cam receiving protrusion 82b are in contact. According to the present embodiment described above, when the cam receiving projections 82 a and 82 b in contact with the cam contact surface 76 are changed as described above, the impact caused by the collision of the cam receiving projections 82 a and 82 b to the cam contact surface 76 is not generated. Or, the cam receiving protrusions 82a, 82b are in contact with the end portions 76a, 76b of the cam abutting surface 76, and the impact is passed to ensure smooth swinging of the handle 70.

而，為實現如以上之凸輪抵接面76與凸輪承接片81，本實施形態中，沿著把手70相對於嬰兒車本體11之搖動軸線da來觀察時，從把手70相對於嬰兒車本體11之搖動軸線da到凸輪抵接面76之各位置的直線距離La會從把手70從第1位置朝第2位置搖動時之移動方向前方側的凸輪抵接面76上其中一端76a朝向移動方向後方側之凸輪抵接面上另一端76b逐漸地變長，且，把手70朝圖21所示之第2位置來配置時，從把手70相對於嬰兒車本體11之搖動軸線da到第2凸輪承接突出部82b之直線距離Lb會比從把手70相對於嬰兒車本體11之搖動軸線da到第1凸輪承接突出部82a之直線距離Lc更短。 In order to realize the cam contact surface 76 and the cam receiving piece 81 as described above, in this embodiment, when viewed along the swing axis da of the handle 70 relative to the stroller body 11, the handle 70 is relative to the stroller body 11. The linear distance La between the swing axis da and each position of the cam contact surface 76 will move from the first position to the second position in the direction of movement when the handle 70 is swung forward. When the other end 76b of the cam contact surface on the side gradually becomes longer, and the handle 70 is disposed toward the second position shown in FIG. 21, the second cam is received from the swing axis da of the handle 70 relative to the stroller body 11 The linear distance Lb of the protrusion 82b is shorter than the linear distance Lc from the swing axis da of the handle 70 with respect to the stroller body 11 to the first cam receiving protrusion 82a.

進而，本實施形態中，沿著把手70相對於嬰兒車本體11之搖動軸線da來觀察時，從把手70相對於嬰兒車本體11之搖動軸線da到凸輪抵接面71各位置的直線距離La會 從把手70從可搖動範圍內其中一側往另一側搖動時之移動方向前方側的凸輪抵接面76上其中一端76a朝向移動方向後方側之凸輪抵接面上另一端76b逐漸地變長，且，如圖16所示，沿著與把手70之搖動軸線da平行之方向的凸輪抵接面76的寬度w會從凸輪抵接面76上其中一端76a朝向移動方向後方側之凸輪抵接面76上另一端76b逐漸地變寬。根據上述實施形態，在距離側面視點下把手70之搖動軸線da之直線距離La變長的凸輪抵接面76上的位置時，凸輪抵接面76之寬度w會變寬。當從把手70之搖動軸線da到凸輪抵接面76上之某一位置之直線距離La變長時，凸輪抵接面76之該位置朝凸輪承接片81抵接之際，來自使凸輪承接片81朝向凸輪抵接面76賦予勢能的賦予勢能構件85的賦予勢能力便變得更大。且，由於距離把手70之搖動軸線da之直線距離La愈長之位置的凸輪抵接面76的寬度w愈寬，因此可將來自賦予勢能構件85之更大的賦予勢能力用凸輪抵接面76當中寬度更寬的部位來承接。即，不需使凸輪抵接面76之大小超過必要以上，便可謀求第1切換構件75與嬰兒車10之小型輕量化。又，可使隨著把手70的搖動之第1切換構件75與第2切換構件80的相對動作變得更順利。 Furthermore, in this embodiment, when viewed along the swing axis da of the handle 70 with respect to the stroller body 11, the linear distance La from each position of the swing axis da of the handle 70 with respect to the stroller body 11 to each position of the cam contact surface 71 meeting One end 76a of the cam abutting surface 76 on the front side in the moving direction when the handle 70 is swung from one side to the other side within the swingable range gradually becomes longer toward the other end 76b of the cam abutting surface on the rear side in the moving direction. Also, as shown in FIG. 16, the width w of the cam abutting surface 76 in a direction parallel to the swing axis da of the handle 70 will abut from one end 76 a of the cam abutting surface 76 toward the cam on the rear side in the moving direction. The other end 76b on the surface 76 gradually becomes wider. According to the above embodiment, the width w of the cam contact surface 76 is widened at a position on the cam contact surface 76 where the straight distance La of the swing axis da of the handle 70 from the side view becomes longer. When the linear distance La from the swing axis da of the handle 70 to a position on the cam contact surface 76 becomes longer, when the position of the cam contact surface 76 abuts against the cam receiving piece 81, the cam receiving piece comes from The potential imparting ability of the potential imparting member 85 imparted to the cam abutting surface 76 toward 81 becomes larger. Further, since the cam contact surface 76 having a longer distance from the swing axis da of the handle 70 to the straight line La has a wider width w, the cam contact surface with a larger potential application force from the potential application member 85 can be used. The wider part of 76 to take over. That is, the size of the first switching member 75 and the stroller 10 can be reduced in size without reducing the size of the cam contact surface 76 more than necessary. In addition, the relative movement of the first switching member 75 and the second switching member 80 with the swing of the handle 70 can be made smoother.

<鎖定構件及車輪保持單元> <Locking member and wheel holding unit>

接著，主要參照圖25~圖27，並且針對軸構件130及車輪保持單元100當中與鎖定構件130相關連的部分來說明。 Next, referring to FIG. 25 to FIG. 27, a portion related to the lock member 130 among the shaft member 130 and the wheel holding unit 100 will be described.

如上所述，鎖定構件130可移動於：限制旋轉體110相對於固定體105之旋轉之圖26的鎖定位置、與旋轉體 110相對於固定體105可旋轉之圖25的鎖定解除位置之間。如圖25與圖26所示，固定體105形成有：朝一方向延伸並且在與旋轉體105相對面之前述一方向之其中一側開口的收容部106。本實施形態中，收容部106朝上下方向延伸，並朝向上下方向之下方來開口。另一方面，在可與固定體105之收容部106於一方向相對面的位置，旋轉體110之支持塊體115形成有卡合凹部114。 As described above, the lock member 130 can be moved between the lock position of FIG. 26 that restricts the rotation of the rotating body 110 relative to the fixed body 105 and the rotating body 110 is between the unlocked position of FIG. 25 which is rotatable with respect to the fixed body 105. As shown in FIG. 25 and FIG. 26, the fixed body 105 is formed with a receiving portion 106 that extends in one direction and is opened in one of the aforementioned directions on the side opposite to the rotating body 105. In the present embodiment, the accommodating portion 106 extends in the up-down direction and opens downward in the up-down direction. On the other hand, at a position which can face the receiving portion 106 of the fixed body 105 in one direction, the supporting block 115 of the rotating body 110 is formed with an engaging recess 114.

鎖定構件130使其長邊方向沿著一方向並配置於收容部106內，且可滑動於收容部106內。鎖定構件130在收容部106內朝一方向之另一側移動的位置是圖25所示之鎖定解除位置，鎖定構件130在鎖定解除位置橫跨其全長地位於固定體105之收容部106內。因此，鎖定構件130處於鎖定解除位置時，鎖定構件130不會限制旋轉體110相對於固定體105的旋轉。另一方面，鎖定構件130在收容部106內朝一方向之其中一側移動的位置是圖26所示之鎖定位置，鎖定構件130在鎖定位置，其之其中一側端會朝收容部106外延伸出去。此時鎖定構件130之其中一側端會延伸進入旋轉體110之卡合凹部114內。因此，鎖定構件130處於鎖定位置時，鎖定構件130便會限制旋轉體110相對於固定體105的旋轉。 The locking member 130 is arranged in the receiving portion 106 with its long side direction along one direction, and is slidable in the receiving portion 106. A position where the lock member 130 moves to the other side in one direction in the accommodation portion 106 is the lock release position shown in FIG. 25, and the lock member 130 is located in the accommodation portion 106 of the fixed body 105 across the entire length in the lock release position. Therefore, when the lock member 130 is in the unlocked position, the lock member 130 does not restrict the rotation of the rotating body 110 relative to the fixed body 105. On the other hand, the position where the locking member 130 moves to one side in one direction in the receiving portion 106 is the locking position shown in FIG. 26, and the locking member 130 is in the locking position, and one end of the locking member 130 extends toward the outside of the receiving portion 106. Go out. At this time, one end of the locking member 130 will extend into the engaging recess 114 of the rotating body 110. Therefore, when the locking member 130 is in the locked position, the locking member 130 restricts the rotation of the rotating body 110 relative to the fixed body 105.

如圖25與圖26所示，固定體105之收容部106內，成為鎖定構件130其中一側的位置配置有壓縮彈簧103。該壓縮彈簧103在收容部106其中一側端面與鎖定構件130之間被壓縮，藉此從一方向之另一側朝其中一側來對鎖定構 件130賦予勢能。如上所述，鎖定構件130連接有傳達器件87之線材87b。且，藉由線材87b隨著把手70的搖動而移動，鎖定構件130對抗壓縮彈簧103之賦予勢能力而被往上拉，鎖定構件130便從鎖定位置朝鎖定解除位置移動。另一方面，藉由線材87b隨著把手70的搖動而移動，鎖定構件130藉由壓縮彈簧103之賦予勢能力被往下壓，鎖定構件130便從鎖定解除位置朝鎖定位置來移動。 As shown in FIG. 25 and FIG. 26, a compression spring 103 is disposed in the accommodation portion 106 of the fixed body 105 as one of the lock members 130. The compression spring 103 is compressed between the one end surface of the receiving portion 106 and the locking member 130, thereby aligning the locking structure from the other side in one direction toward one of the sides. Piece 130 gives potential energy. As described above, the wire member 87 b of the transmission device 87 is connected to the lock member 130. Furthermore, by moving the wire 87b with the swing of the handle 70, the lock member 130 is pulled upward against the force imparted by the compression spring 103, and the lock member 130 moves from the locked position to the unlocked position. On the other hand, when the wire 87b moves with the swing of the handle 70, the lock member 130 is pushed down by the potential imparting force of the compression spring 103, and the lock member 130 moves from the unlocked position to the locked position.

然而，本實施形態之鎖定構件130包含有承接壓縮彈簧103之一方向其中一側端的彈簧承接面131a，此外，鎖定構件130具有比彈簧承接面131a更朝一方向另一側延伸出去並位於壓縮彈簧103側邊的彈簧側延出部135。如圖25所示，鎖定構件130在收容部106內朝一方向其中一側滑動而處於鎖定解除位置時，彈簧側延出部135之長度便會比在彈簧承接面131a與收容部106其中一側端面之間所壓縮之壓縮彈簧103的長度更短一些。上述鎖定構件130藉由利用配置壓縮彈簧103之區域而不使在收容部106之一方向上的長度變長，即可使其全長變長。即，不使車輪保持單元100大型化與重量化，便可使鎖定構件130變長。且，藉由使鎖定構件130變長，即使將用以確保鎖定構件130確實滑動的間隙設置於鎖定構件130與收容部106之間，亦可有效地抑制在收容部106內之鎖定構件130的晃動，便可實現鎖定構件130之順利的滑動動作。藉此，便可更加確實地實行旋轉體110相對於固定體105可旋轉之狀態與旋轉體110相對於固定體105不可旋轉之狀態的切換。 However, the locking member 130 of this embodiment includes a spring receiving surface 131a for receiving one end of one direction of the compression spring 103, and the locking member 130 has a compression spring extending in one direction and located on the other side than the spring receiving surface 131a. The spring-side extension 135 on the side of 103. As shown in FIG. 25, when the locking member 130 slides in one direction in one side of the receiving portion 106 and is in the unlocked position, the length of the spring-side extending portion 135 is longer than one of the spring receiving surface 131a and the receiving portion 106 The length of the compression spring 103 compressed between the end faces is shorter. The lock member 130 can be made longer by using a region where the compression spring 103 is disposed without increasing the length in one direction of the receiving portion 106. That is, the lock member 130 can be made longer without increasing the size and weight of the wheel holding unit 100. In addition, by making the lock member 130 longer, even if a gap for ensuring that the lock member 130 slides is provided between the lock member 130 and the storage portion 106, it is possible to effectively suppress the lock member 130 in the storage portion 106. The smooth sliding action of the locking member 130 can be achieved by shaking. Thereby, switching between the state in which the rotating body 110 can rotate with respect to the fixed body 105 and the state in which the rotating body 110 cannot rotate with respect to the fixed body 105 can be performed more reliably.

又，本實施形態中，如圖27所示，彈簧側延出部135具有：一對側壁部136、與連結一對側壁部136間之連結壁部137。壓縮彈簧103之至少一方向其中一側的部分會由彈簧側延出部135從三方來包圍。因此，隨著鎖定構件130之在收容部106內之滑動的壓縮彈簧103的壓縮與膨脹則利用彈簧側延出部135來引導。藉此，鎖定構件130在收容部106內之滑動動作便會更加安定。例如，鎖定構件130從鎖定位置朝鎖定解除位置移動時，壓縮彈簧103便承接壓縮力，此時亦可有效地防止壓縮彈簧103屈曲而朝與一方向正交的方向突出。藉此，鎖定構件130在收容部106內之滑動動作便更加安定。 In this embodiment, as shown in FIG. 27, the spring-side extension portion 135 includes a pair of side wall portions 136 and a connection wall portion 137 connecting the pair of side wall portions 136. A portion of one side of the compression spring 103 in at least one direction is surrounded by the spring-side extension portion 135 from three sides. Therefore, the compression and expansion of the compression spring 103 as the lock member 130 slides in the receiving portion 106 is guided by the spring-side extension portion 135. As a result, the sliding movement of the locking member 130 in the receiving portion 106 becomes more stable. For example, when the lock member 130 moves from the locked position to the unlocked position, the compression spring 103 receives the compression force. At this time, the compression spring 103 can also be effectively prevented from buckling and protruding in a direction orthogonal to one direction. Thereby, the sliding movement of the locking member 130 in the receiving portion 106 becomes more stable.

<<布片150>> << 布 片 150 >>

接著，主要參照圖1、圖2及圖28~圖30，針對支持於布片支持單元40上之布片150來說明。如圖28所詳示，布片150整體地以沿著前後方向來延伸之寬度方向中心面為中心而成為大致對稱的構成。 Next, the cloth sheet 150 supported on the cloth sheet supporting unit 40 will be described mainly with reference to FIGS. 1, 2 and 28 to 30. As shown in detail in FIG. 28, the cloth sheet 150 has a substantially symmetrical configuration with the center of the width direction center plane extending along the front-back direction as a whole.

如圖1、圖2及圖28~圖30所示，布片150具有：座面部156、與座面部156連接且位於座面部156後方之靠背部157、從座面部156朝兩側邊延伸出去之左右的側面部160、及從靠背部157延伸出去之左右的上方側面部167。座面部156主要支持搭乘嬰兒車10之嬰幼兒的臀部。另一方面，靠背部157會配置於與嬰幼兒背部相對面的位置。側面部(第1側面部)160與上方側面部(第2側面部)167則構成位於嬰幼兒側邊之側壁部。又，布片150更具有連接於成為靠背部157之從座面部156分開之上方之位置的上方部169。如圖4所示，上方部169將左右之上方側面部167連結，並具有作為頭靠之功能。 As shown in FIGS. 1, 2 and 28 to 30, the cloth sheet 150 includes a seat surface portion 156, a backrest portion 157 connected to the seat surface portion 156 and located behind the seat surface portion 156, and extending from the seat surface portion 156 to both sides. The left and right side portions 160 and the left and right upper side portions 167 extending from the backrest portion 157. The seat surface 156 mainly supports the hips of infants and young children who ride the stroller 10. On the other hand, the backrest portion 157 is disposed at a position facing the back of the infant. The side surface portion (first side surface portion) 160 and the upper side surface portion (second side surface portion) 167 constitute a side wall portion located on the side of the infant. Further, the cloth sheet 150 further includes an upper portion 169 connected to a position above the seat back portion 157 separated from the seat surface portion 156. As shown in FIG. 4, the upper portion 169 connects the left and right upper side portions 167 and functions as a headrest.

如上所述，座面部156主要是利用布片支持單元40之座面部支持元件50來支持。如圖28所示，座面部156在其後緣部與靠背部157連接，在一對側緣部與個別對應之側的側面部160連接。靠背部157主要是利用布片支持單元40之靠背部支持元件60來支持。如圖28所示，靠背部157在平面視點下，會大致成為矩形形狀其中一方的短邊為曲線狀 的倒角形狀。靠背部157會配置成整形成該曲線狀的緣部從座面部156朝後方或上方分開。 As described above, the seat surface portion 156 is mainly supported by the seat surface support element 50 of the cloth support unit 40. As shown in FIG. 28, the seat surface portion 156 is connected to the backrest portion 157 at a rear edge portion thereof, and is connected to a pair of side edge portions to side portions 160 on respective corresponding sides. The backrest portion 157 is mainly supported by the backrest support element 60 of the fabric support unit 40. As shown in FIG. 28, the backrest portion 157 has a substantially rectangular shape when viewed from a plane, and one of the short sides is curved. Chamfered shape. The backrest part 157 is arrange | positioned so that the curve-shaped edge part may be separated from the seat surface part 156 toward the back or upper part.

靠背部157在其下緣部與座面部156之後緣部連接。靠背部157與座面部156例如藉由縫合而彼此連接，此時，靠背部157與座面部156之連接處由延伸成線狀之縫製線來區劃。隨著嬰兒車本體11之傾斜動作或折疊動作，布片150之座面部156與靠背部157會彼此接近。此時，座面部156與靠背部157以縫製線所構成之線狀連接處為搖動軸線可相對地搖動。 The backrest portion 157 is connected to the rear edge portion of the seat surface portion 156 at its lower edge portion. The backrest portion 157 and the seat surface portion 156 are connected to each other by, for example, sewing. At this time, the connection portion of the backrest portion 157 and the seat surface portion 156 is divided by a sewing line extending in a linear shape. As the stroller body 11 is tilted or folded, the seat surface 156 and the backrest portion 157 of the cloth sheet 150 will approach each other. At this time, the thread-shaped connection point of the seat surface portion 156 and the backrest portion 157 formed by the sewing line can be relatively shaken as the swing axis.

靠背部157之直線狀一對側緣部連接有各上方側面部167。 A pair of linear side edge portions of the backrest portion 157 are connected to the respective upper side surface portions 167.

又，靠背部157之曲線狀上緣部連接有具有作為頭靠之功能的上方部169。一對上方側面部167支持於布片支持單元40之側邊支持元件45，上方部169由布片支持單元40之上方支持元件41來支持。圖28所示之例中，一對上方側面部167與上方部169利用相同材料而構造成一體。該例中，一對上方側面部167與上方部169例如藉由縫合而與靠背部157連接。此時，上方側面部167以及上方部169與靠背部157之連接處會利用延伸成略U字狀之縫製線來區劃。如上所述，上方支持元件41相對於靠背部支持元件60而可搖動。隨著上方支持元件41之相對於靠背部支持元件60的搖動，上方部169便會以縫製線所構成之線狀連接處為搖動軸線，相對於靠背部157而搖動。 An upper portion 169 having a function as a headrest is connected to a curved upper edge portion of the backrest portion 157. A pair of upper side portions 167 are supported by the side support elements 45 of the fabric support unit 40, and the upper portion 169 is supported by the upper support elements 41 of the fabric support unit 40. In the example shown in FIG. 28, the pair of upper side portions 167 and the upper portion 169 are integrally formed using the same material. In this example, the pair of upper side portions 167 and the upper portion 169 are connected to the backrest portion 157 by, for example, sewing. At this time, the connecting portions of the upper side portion 167 and the upper portion 169 and the backrest portion 157 are divided by a sewing line extending into a U-shape. As described above, the upper support member 41 is swingable relative to the backrest support member 60. With the swing of the upper support element 41 relative to the backrest support element 60, the upper portion 169 will swing with respect to the backrest portion 157 with the linear connection formed by the sewing thread as the swing axis.

另一方面，由圖1與圖2可理解到，側邊支持元件 45不依靠傾斜動作便相對於利用靠背部支持元件60所區劃之面維持成立起之狀態。因此，不依靠傾斜動作而由側邊支持元件45支持之上方側面部167便會在倚靠於靠背部157之嬰幼兒側邊立起。上方側面部167在位於嬰幼兒頭部側邊之上方具有較寬之寬度。另一方面，在與座面部156接近之下方具有較窄之寬度，由圖29與圖30可理解到，是構造成不妨礙座面部156與靠背部157的接近。 On the other hand, it can be understood from FIG. 1 and FIG. 2 that the side supporting element 45 does not rely on the tilting action, and maintains its established state with respect to the area partitioned by the backrest support member 60. Therefore, the upper side portion 167 supported by the side support element 45 without relying on the tilting action will stand on the side of the infant leaning against the backrest portion 157. The upper side portion 167 has a wider width above the side of the head of the infant. On the other hand, it has a relatively narrow width below the seat surface portion 156, and it can be understood from FIGS. 29 and 30 that the structure does not hinder the approach of the seat surface portion 156 and the backrest portion 157.

座面部156、靠背部157、上方側面部167及上方部169可與搭乘嬰兒車10之嬰幼兒直接接觸。故，座面部156、靠背部157、上方側面部167及上方部169會使用具有緩衝性之布材來構成，例如可使用將具有緩衝性之海綿等之材料以二片布料來包夾的布材、或具有緩衝性之布料本身構成的布材來構成。又，用於座面部156、靠背部157、上方側面部167及上方部169之布材亦可包含補強板等來補強。又，考慮到清洗布片150，布片150宜固定成可從嬰兒車本體11取下。可使用安裝於布片150之各位置的鈕扣等公認的連結件來實現布片150之朝嬰兒車本體11的固定。 The seat surface portion 156, the backrest portion 157, the upper side portion 167, and the upper portion 169 may be in direct contact with the infant and child who rides the stroller 10. Therefore, the seat surface portion 156, the backrest portion 157, the upper side portion 167, and the upper portion 169 are made of a cushioning cloth. For example, a cloth having a cushioning sponge or the like can be used to wrap the cloth in two pieces. Material, or a cloth material made of a cushioning cloth itself. In addition, the cloth material used for the seat surface portion 156, the backrest portion 157, the upper side portion 167, and the upper portion 169 may include a reinforcing plate or the like for reinforcement. Considering that the cloth sheet 150 is cleaned, the cloth sheet 150 is preferably fixed to be removable from the stroller body 11. The fastening of the cloth sheet 150 toward the stroller body 11 can be achieved by using a recognized connection member such as a button installed at each position of the cloth sheet 150.

接著，針對左右之側面部160來詳述。如圖28~圖30所示，各側面部160具有：連接於座面部156之側面本體部161、以及至少一部分配置於與所對應之側的上方側面部167之背面相對面的位置且與側面本體部161、靠背部157及上方側面部167之至少一方連接的側面連結部165。考慮到外觀面，宜為不依靠傾斜狀態，即，即使在如圖2與圖30所示的靠背部157相對於座面部156在最倒下之狀態時，側 面本體部161之後方側之緣部亦延伸到與上方側面部167之背面相對面的位置為止，換言之，側面連結部165位於上方側面部167及/或靠背部157之背面側，不會露出於與嬰幼兒相對面之側。而，在此，將與搭乘嬰兒車10之嬰幼兒相對面之表面相反側的面稱為「背面」。 Next, the left and right side portions 160 will be described in detail. As shown in FIGS. 28 to 30, each side portion 160 includes a side body portion 161 connected to the seat surface portion 156, and at least a part of the side body portion 161 disposed at a position opposite to the back surface of the upper side portion 167 on the corresponding side and side-to-side A side connection portion 165 to which at least one of the main body portion 161, the backrest portion 157, and the upper side portion 167 is connected. In consideration of the appearance surface, it is preferable not to rely on the inclined state, that is, even when the backrest portion 157 shown in FIG. 2 and FIG. The edge portion on the rear side of the surface body portion 161 also extends to a position opposite to the back surface of the upper side portion 167. In other words, the side connection portion 165 is located on the back side of the upper side portion 167 and / or the backrest portion 157 and is not exposed. On the side opposite the baby. Here, the surface on the opposite side to the surface facing the infant on board the stroller 10 is referred to as a "back surface".

所圖示之例中，左側之側面部160之側面連結部165與靠背部157之左側側緣部連接，右側之側面部160之側面連結部165與靠背部157之右側側緣部連接。又所圖示之例中，左側之側面部160之側面連結部165在靠背部157及左側之上方側面部167之連接處從背面側來連接，右側之側面部160之側面連結部165在靠背部157與右側之上方側面部167之連接處從背面側來連接。各側面部160之側面連結部165亦可與靠背部157所對應之側的側緣部及所對應之側的上方側面部167的兩方重疊地來縫合。另一方面，所圖示之例中，左側之側面部160之側面本體部161與座面部156之左側側緣部連接，進而，與靠背部157下方部分之左側側緣部來連接。同樣地，右側之側面部160之側面本體部161與座面部156之右側側緣部連接，進而，與靠背部157下方部分之右側側緣部來連接。各側面部160之側面本體部161亦可與座面部156及靠背部157所對應之側的側緣部重疊地縫合。 In the illustrated example, the side connection portion 165 of the left side portion 160 is connected to the left side edge portion of the backrest portion 157, and the side connection portion 165 of the right side portion 160 is connected to the right side edge portion of the backrest portion 157. In the illustrated example, the side connection portion 165 of the left side portion 160 is connected from the back side at the connection portion of the backrest portion 157 and the left upper side portion 167, and the side connection portion 165 of the right side portion 160 is at the backrest. The connection portion between the portion 157 and the upper right side portion 167 is connected from the back side. The side connection portion 165 of each side portion 160 may be stitched so as to overlap with both the side edge portion on the side corresponding to the backrest portion 157 and the upper side portion 167 on the corresponding side. On the other hand, in the illustrated example, the side body portion 161 of the left side surface portion 160 is connected to the left side edge portion of the seat surface portion 156 and is further connected to the left side edge portion of the lower portion of the backrest portion 157. Similarly, the side body portion 161 of the right side portion 160 is connected to the right side edge portion of the seat surface portion 156 and is further connected to the right side edge portion of the lower portion of the backrest portion 157. The side body portion 161 of each side portion 160 may be sewn to overlap with the side edge portion on the side corresponding to the seat surface portion 156 and the backrest portion 157.

所圖示之例中，各側面部160在其側面本體部161與側面連結部165，會與座面部156及靠背部157連續地連接。特別是所圖示之例中，各上方側面部167與靠背部157 之連接處下方端的位置會與側面部160之朝靠背部157之連接緣當中側面本體部161與側面連結部165之分界的位置為一致。 In the illustrated example, each side portion 160 is continuously connected to the seat surface portion 156 and the backrest portion 157 at the side body portion 161 and the side connection portion 165. In particular, in the illustrated example, each of the upper side portions 167 and the backrest portion 157 The position of the lower end of the connection point is consistent with the position of the boundary between the side body portion 161 and the side connection portion 165 among the connection edges of the side portion 160 toward the backrest portion 157.

而，從有效地防止側面部160朝寬度方向內側傾倒，或是在寬度方向外側變形而朝寬度方向擴張之情形的觀點來看，側面部160之側面連結部165宜比側面部160之側面本體部161更容易變形。作為一例，宜將側面部160之側面連結部165使用比側面部160之側面本體部161更容易變形之布料來形成。具體而言，亦可以與上述座面部156、靠背部157、上方側面部167及上方部169相同地具有緩衝性之材料來構成側面本體部161，並以單純的布料來構成側面連結部165。 Further, from the viewpoint of effectively preventing the side portion 160 from falling down inward in the width direction or being deformed outward in the width direction and expanding in the width direction, the side connection portion 165 of the side portion 160 should be better than the side body of the side portion 160. The portion 161 is more easily deformed. As an example, it is preferable that the side surface connecting portion 165 of the side surface portion 160 be formed using a cloth that is more easily deformed than the side surface body portion 161 of the side surface portion 160. Specifically, the side body portion 161 may be composed of a cushioning material similar to that of the seat surface portion 156, the backrest portion 157, the upper side portion 167, and the upper portion 169, and the side connection portion 165 may be formed of a simple cloth.

側面本體部161保持成從座面部156豎起之姿勢，並與搭乘嬰兒車10之嬰幼兒從側邊相對面。由此點看來，可與嬰幼兒接觸之側面本體部161宜使用具有緩衝性之材料來形成。例如，宜使用將具有緩衝性之海綿等之材料以二片布料包夾的布材等具有自立性之布材來構成側面本體部161。 The side body portion 161 is held in an upright posture from the seat surface portion 156, and faces the infant from the side in the infant carriage 10. From this point of view, it is preferable that the side body portion 161 that can contact the infant is formed of a cushioning material. For example, it is preferable to use a self-supporting cloth material such as a cloth material in which a material such as a sponge having cushioning properties is sandwiched between two cloths to constitute the side body portion 161.

又，如圖28~圖30所詳示，各側面部160之側面本體部161形成有第1折痕162a與第2折痕162b。如圖28~圖30所詳示，折痕162a、162b會大致依循以座面部156與靠背部157之搖動軸線之座面部156與靠背部157的連接處側端為中心的放射線路徑來延伸。側面本體部161利用二道折痕162a、162b區劃成：與座面部156連接之第1部分161a、與 側面連結部165連接之第3部分161c、及配置於第1部分161a與第3部分161c之間的第2部分161b。 As shown in detail in FIGS. 28 to 30, the first side fold 162 a and the second fold 162 b are formed in the side body portion 161 of each side portion 160. As shown in detail in FIGS. 28 to 30, the creases 162 a and 162 b generally extend along a radiation path centered on the side of the joint between the seat surface portion 156 and the backrest portion 157 on the swing axis of the seat surface portion 156 and the backrest portion 157. The side body portion 161 is divided into two folds 162a and 162b: a first portion 161a connected to the seat surface portion 156, and The third portion 161c connected by the side connection portion 165 and the second portion 161b disposed between the first portion 161a and the third portion 161c.

折痕162a、162b是比側面本體部161之其他處更容易變形且延伸成線狀的區域。所圖示之例中，折痕162a、162b作為形成於具有緩衝性之布材的縫製線來形成。又，作為縫製線以外之形態，亦可利用並排成線狀而形成之貫通孔、或熱壓縮之線，來形成折痕162a、162b。 The creases 162 a and 162 b are regions that are more easily deformed and extend in a linear shape than the other parts of the side body portion 161. In the illustrated example, the creases 162a and 162b are formed as sewing lines formed on a cloth material having cushioning properties. In addition, as a form other than the sewing line, creases 162a and 162b may be formed by using a through-hole formed side by side in a line shape or a thermally compressed line.

接著，針對如以上構成而成之本實施形態之布片150的作用與效果來說明。 Next, the operation and effect of the cloth sheet 150 of the present embodiment configured as described above will be described.

首先，根據本實施形態，布片150之側面部160與布片支持單元40透過連結件46、153可取下地連結。因 此，如圖1與圖2，或是，如圖29與圖30所示，可有效地抑制隨著嬰兒車本體11之傾斜動作等而朝寬度方向內側傾倒或朝寬度方向外側擴張之情形。即，根據本實施形態，可有效地防止側面部160朝內側傾倒而側面部160從嬰兒車本體11分開的情形。因此，可有效地避免在布片150與嬰兒車本體11之間夾入衣服等的情形。又，朝內側傾倒之側面部160在嬰幼兒搭乘嬰兒車10時，亦會阻礙嬰幼兒乘坐於座面部156。故，藉由防止側面部160朝內側傾倒，可安定且容易地使嬰幼兒適切地搭乘嬰兒車10。進而，欲防止側面部160朝內側傾倒，外觀上而言亦以此為佳。此外，由於可有效地防止側面部160朝寬度方向外側擴張，因此在嬰兒車本體11之折疊動作時與展開動作時，可有效地避免側面部160干涉嬰兒車本體11。藉此，可安定地實施嬰兒車10之折疊操作與展開操作。 First, according to this embodiment, the side surface portion 160 of the cloth sheet 150 and the cloth sheet support unit 40 are removably connected through the connecting members 46 and 153. because Therefore, as shown in FIGS. 1 and 2 or as shown in FIGS. 29 and 30, it is possible to effectively prevent the baby body 11 from being tilted inward in the width direction or expanded outward in the width direction as the stroller body 11 is tilted or the like. That is, according to the present embodiment, it is possible to effectively prevent the side surface portion 160 from falling inward and the side surface portion 160 being separated from the stroller body 11. Therefore, it is possible to effectively avoid a situation in which clothes and the like are sandwiched between the cloth sheet 150 and the stroller body 11. In addition, the side surface portion 160 that is tilted inward prevents the infant from riding on the seat surface 156 when the infant is riding the stroller 10. Therefore, by preventing the side portion 160 from falling inward, the infant can ride the stroller 10 appropriately and stably. Furthermore, in order to prevent the side portion 160 from falling inward, it is also preferable in terms of appearance. In addition, since the side portion 160 can be effectively prevented from expanding outward in the width direction, the side portion 160 can be effectively prevented from interfering with the stroller body 11 during the folding operation and the unfolding operation of the stroller body 11. Thereby, the folding operation and the unfolding operation of the stroller 10 can be performed stably.

又同時，連結件46會設於布片支持單元40當中在傾斜動作時相對於本體框15相對搖動之構件，具體而言就是側邊支持元件45。因此，布片150之側面部160中透過連結件46、153而與側邊支持元件45連接之部分與至少其附近的部分可隨著嬰兒車10之布片支持單元40的傾斜動作而動作。因此，藉由適宜地設定連結件46、153之安裝位置，側面部160便可相對於因傾斜動作而移動之靠背部157常時配置於適切的位置。藉此，可充分抑制布片之側面部朝寬度方向內側之傾倒或朝寬度方向外側之擴張，並且布片之側面部可相對於靠背部位於適當的位置。 At the same time, the connecting member 46 is provided in the cloth supporting unit 40, which is a member that relatively swings relative to the main body frame 15 during the tilting operation, specifically, the side supporting element 45. Therefore, the portion of the side surface 160 of the cloth sheet 150 that is connected to the side support element 45 through the connecting members 46 and 153 and at least the vicinity thereof can move with the tilting operation of the cloth sheet support unit 40 of the stroller 10. Therefore, by appropriately setting the attachment positions of the coupling members 46 and 153, the side surface portion 160 can always be arranged at an appropriate position with respect to the backrest portion 157 moved by the tilting action. Thereby, it is possible to sufficiently suppress the side portion of the cloth sheet from falling down toward the inner side in the width direction or expanding outwardly in the width direction, and the side portion of the cloth sheet can be positioned at an appropriate position with respect to the backrest portion.

又，上述實施形態中，側邊支持元件45當中設有連結件46之部位在嬰兒車10之側面視點下會配置於從側邊支持元件45之往本體框15之搖動軸線sc1的前下方連結部45a偏移的位置且成為搖動軸線sc1附近的位置。因此，可將側面部160相對於靠背部157適當地配置，另一方面，隨著靠背部157之傾斜動作，側面部160之安裝有連結件153的部位會大幅移動，可更安定地防止側面部160當中設有連結件153之部位以外的部分，例如側面部160當中與座面部156連接之部分及設有連結件153的部分之間的部分，更詳而言之即是側面本體部161之第2部分161b朝寬度方向內側或外側傾倒。 Further, in the above-mentioned embodiment, the portion provided with the connecting member 46 among the side support members 45 is arranged at the front and lower sides of the swing axis sc1 from the side support member 45 to the main body frame 15 in a side view of the stroller 10. The position of the portion 45a is shifted to a position near the swing axis sc1. Therefore, the side portion 160 can be appropriately arranged with respect to the backrest portion 157. On the other hand, as the backrest portion 157 is tilted, the portion of the side portion 160 where the coupling member 153 is attached moves greatly, and the side portion can be prevented more securely. The portion 160 other than the portion where the link 153 is provided, such as the portion between the side portion 160 that is connected to the seat surface portion 156 and the portion where the link 153 is provided, more specifically, the side body portion 161 The second portion 161b is poured inward or outward in the width direction.

進而，本實施形態中，如圖8與圖9所示，側邊支持元件45當中設有連結件46之部位在嬰兒車10之側面視點下，在側邊支持元件45相對於本體框15朝上方搖動之狀態下是位於比該側邊支持元件45之相對於本體框15的搖動軸線SC1更上方，且在側邊支持元件45相對於本體框15朝後方搖動之狀態下是位於比側邊支持元件45之相對於本體框15之搖動軸線sc1更後方。進而，側邊支持元件45當中設有連結件46之部位在嬰兒車10之側面視點下，側邊支持元件45相對於本體框15朝上方搖動之狀態，會比側邊支持元件45相對於本體框15朝後方搖動之狀態位於更前方且更上方。因此，靠背部157相對於座面部156會豎起，在嬰幼兒坐於布片150上之狀態下，側面部160會相對地朝前方移動並朝上方上拉。藉此，利用側面部160，可將坐於嬰兒車10之嬰 幼兒從側邊適當地保護。另一方面，在靠背部157相對於座面部156傾倒且嬰幼兒安睡於布片150上之狀態下，側面部160會相對地朝後方移動。藉此，利用側面部160與上方側面部167，便可將安睡於嬰兒車10之嬰幼兒從側邊適當地保護。 Furthermore, in the present embodiment, as shown in FIGS. 8 and 9, the portion where the connecting member 46 is provided in the side support member 45 faces the side view of the stroller 10, and the side support member 45 faces the main frame 15 It is located above the swing axis SC1 of the side support member 45 with respect to the main body frame 15 in the state of swinging upward, and is located on the side when the side support element 45 is swinging rearward with respect to the body frame 15 The supporting element 45 is further rearward with respect to the swing axis sc1 of the main body frame 15. Further, in a side view of the stroller 10 where the connecting member 46 is provided in the side support member 45, the state where the side support member 45 is swung upward relative to the main body frame 15 is higher than that of the side support member 45 relative to the main body. The state in which the frame 15 is swung backward is located further forward and upward. Therefore, the backrest portion 157 is erected relative to the seat surface portion 156. When the infant is sitting on the cloth sheet 150, the side portion 160 is relatively moved forward and pulled upward. Thereby, the baby sitting in the stroller 10 can use the side portion 160 Young children are properly protected from the side. On the other hand, in a state where the backrest portion 157 is tilted relative to the seat surface portion 156 and the infant is sleeping on the cloth sheet 150, the side surface portion 160 is relatively moved rearward. Accordingly, the infants and children sleeping in the stroller 10 can be appropriately protected from the side by using the side portion 160 and the upper side portion 167.

進而，根據本實施形態，安裝於嬰兒車本體11之布片150側壁的部分會分割成：從座面部156側延伸出去之側面部160、與從靠背部157延伸出去之上方側面部167。因此，如圖1與圖2或是圖29與圖30所示，隨著嬰兒車本體11之傾斜動作等，從靠背部157傾倒之狀態豎起時，側面部160與上方側面部167便可相對地移動。故，可有效地抑制側面部160例如朝寬度方向內側傾倒，或是招致朝寬度方向的某種變形而朝寬度方向外側擴張的情形。 Furthermore, according to this embodiment, a portion of the side wall of the cloth sheet 150 attached to the stroller body 11 is divided into a side portion 160 extending from the seat surface portion 156 side and an upper side portion 167 extending from the backrest portion 157. Therefore, as shown in FIG. 1 and FIG. 2 or FIG. 29 and FIG. 30, when the baby carriage body 11 is tilted, etc., the side portion 160 and the upper side portion 167 may be erected when the seat back portion 157 is tilted up. Move relatively. Therefore, it is possible to effectively suppress the side portion 160 from falling down inward in the width direction, or causing some deformation in the width direction to expand outward in the width direction.

又，側面部160利用配置於從背面側與上方側面部167相對面的位置的側面連結部165與靠背部157連接。故，布片150之裝卸較容易。 Further, the side surface portion 160 is connected to the backrest portion 157 by a side surface connection portion 165 disposed at a position facing the upper side portion 167 from the rear surface side. Therefore, assembling and removing the cloth sheet 150 is easier.

進而，根據本實施形態，側面連結部165是由比側面本體部161之材料更容易變形之材料來構成。根據上述布片150，隨著嬰兒車本體11之傾斜動作或折疊動作，布片150之靠背部157相對於座面部156之傾斜角度變化時，連結靠背部157與座面部156的側面部160是在位於上方側面部167之背面側的側面連結部165變得容易變形，便可抑制在側面本體部161的變形。藉此，座面部156與靠背部157接近且上方側面部167與側面部160相對移動時，可有效地防止 側面部160之側面本體部161朝寬度方向內側傾倒或朝寬度方向外側擴張。 Furthermore, according to this embodiment, the side connection portion 165 is made of a material that is more easily deformed than the material of the side body portion 161. According to the cloth sheet 150 described above, when the inclination angle of the backrest portion 157 with respect to the seat surface portion 156 changes with the tilting or folding action of the stroller body 11, the side portion 160 connecting the backrest portion 157 and the seat surface portion 156 is The side coupling portion 165 located on the back side of the upper side portion 167 is easily deformed, and deformation of the side body portion 161 can be suppressed. Thereby, when the seat surface portion 156 and the backrest portion 157 are close to each other and the upper side portion 167 and the side portion 160 are relatively moved, it is possible to effectively prevent The side body portion 161 of the side portion 160 is tilted inward in the width direction or expanded outward in the width direction.

進而，根據上述實施形態，側面部160會通過座面部156及靠背部157之連接處側邊端的位置並透過延伸成線狀之連接處將座面部156與靠背部157連接。故，在搭乘嬰兒車10之嬰幼兒腰部分附近的位置，可防止布片150形成有孔或間隙，在安全面上以此為佳。 Furthermore, according to the above-mentioned embodiment, the side surface portion 160 connects the seat surface portion 156 and the backrest portion 157 through the positions of the side ends of the joint portion of the seat surface portion 156 and the backrest portion 157 and extends through the linear connection portion. Therefore, at the position near the waist portion of the infant and child who rides the stroller 10, it is possible to prevent the cloth sheet 150 from forming a hole or a gap, which is preferable on the safety surface.

進而，根據上述實施形態，側面連結部165與靠背部157之連接處，以及，側面連結部165與側面本體部161之分界大致會沿著以座面部156與靠背部157之搖動軸線為中心之放射線的一條軌跡來延伸。因此，隨著嬰兒車本體11之傾斜動作或折疊動作，布片150之靠背部157相對於座面部156之傾斜角度變化時，將靠背部157與座面部156連結之側面部160在位於上方側面部167之背面側之側面連結部165便容易變形。藉此，可更加有效地防止側面部160之側面本體部161朝寬度方向內側傾倒或朝寬度方向外側擴張。 Furthermore, according to the above-mentioned embodiment, the junction between the side connection portion 165 and the backrest portion 157, and the boundary between the side connection portion 165 and the side body portion 161 substantially follows the center of the swing axis of the seat surface portion 156 and the backrest portion 157. A trajectory of radiation extends. Therefore, with the tilting or folding action of the stroller body 11, when the tilt angle of the backrest portion 157 of the cloth sheet 150 with respect to the seat surface portion 156 changes, the side portion 160 connecting the backrest portion 157 and the seat surface portion 156 is located on the upper side. The side surface connecting portion 165 on the back side of the portion 167 is easily deformed. Thereby, it is possible to more effectively prevent the side body portion 161 of the side portion 160 from falling toward the inside in the width direction or expanding toward the outside in the width direction.

進而，根據本實施形態，側面部160之側面本體部161形成有第1折痕162a與第2折痕162b。且，這些折痕162a、162b會大致朝以座面部156與靠背部157之搖動軸線為中心之放射線狀來延伸。例如嬰兒車10折疊時，靠背部157與座面部156非常接近之情形下，側面部160不只在側面連結部165變形，亦在第1折痕162a與第2折痕162b折曲，使第1部分161a、第2部分161b及第3部分161c重疊而側面本體部161便可折疊。藉此，可有效地防止嬰兒車10折疊時之側 面部160朝寬度方向內側的傾倒及朝寬度方向外側的擴張。 Furthermore, according to the present embodiment, the first side fold 162a and the second fold 162b are formed in the side body portion 161 of the side portion 160. These creases 162a and 162b extend substantially in a radial shape centered on the swing axis of the seat surface portion 156 and the backrest portion 157. For example, when the stroller 10 is folded, when the backrest portion 157 and the seat surface portion 156 are very close to each other, the side portion 160 is deformed not only at the side connection portion 165 but also at the first crease 162a and the second crease 162b. The portion 161a, the second portion 161b, and the third portion 161c overlap, and the side body portion 161 can be folded. Thereby, the side when the stroller 10 is folded can be effectively prevented The face 160 is tilted toward the inner side in the width direction and expanded toward the outer side in the width direction.

進而，根據本實施形態，側面本體部161之第1~第3部分第1部分161a、161b、161c之各部分，設有補強構件163a、163b、163c。利用該補強構件163a、163b、163c，亦可有效地防止在靠背部157傾斜時或嬰兒車10折疊時之側面部160朝寬度方向內側的傾倒及朝寬度方向外側之擴張。特別是，設於第3部分161c之補強構件163c會配置於連結件153的附近。因此，即使側面部160隨著側邊支持元件45之動作而動作，利用位於連結側邊支持元件45與側面部160之連結件46、153之附近的補強構件163c，亦可有效地防止側面部160朝側面部160之寬度方向內側的傾倒及朝寬度方向外側的擴張。 Furthermore, according to this embodiment, the reinforcing members 163a, 163b, and 163c are provided in each of the first to third portions of the side body portion 161, 161a, 161b, and 161c. The reinforcing members 163a, 163b, and 163c can also effectively prevent the side surface portion 160 from falling inward in the width direction and expanding outward in the width direction when the backrest portion 157 is inclined or when the stroller 10 is folded. In particular, the reinforcing member 163c provided in the third portion 161c is disposed near the link 153. Therefore, even if the side portion 160 moves in accordance with the movement of the side support member 45, the side member 160 can be effectively prevented by the reinforcing member 163c located near the coupling members 46 and 153 connecting the side support member 45 and the side portion 160. The side 160 is tilted toward the inner side in the width direction and expanded toward the outer side in the width direction.
