Description

嬰兒車 Baby carriage

發明領域 Field of invention

本發明是有關於一種嬰兒車，特別是關於一種在與嬰幼兒面對的狀態下行進時可輕易將位於行進方向前方之車輪抬起的嬰兒車。 The present invention relates to a stroller, and more particularly to a stroller that can easily lift a wheel in front of a traveling direction when traveling in a state facing the infant.

發明背景 Background of the invention

以往，已知有一種使嬰幼兒面朝行進方向之前方而使嬰幼兒乘車的嬰兒車。近來，具備可在由側面看來比鉛直軸更朝後方傾斜之背面推動位置、與朝比鉛直軸更前方傾斜之面對推動位置之間搖動之把手的嬰兒車也已經廣為普及(參照JP2002-220060A)。這種嬰兒車中，當把手位於背面推動位置時，操作者(保護者)，可從嬰幼兒之背面側握持住把手。而且，操作者能夠使嬰幼兒面朝行進方向之前方而將嬰兒車推動前進。另一方面，當把手位於面對推動位置時，操作者可從面對嬰幼兒之前腳側把握住把手。並且，操作者能夠以後腳側為行進方向之前方而將嬰兒車推動前進。 In the past, there has been known a stroller in which an infant is placed in front of the traveling direction to allow an infant to ride. Recently, a stroller having a backrest pushing position that is inclined more rearward than the vertical axis from the side and a rocking handle that is inclined toward the front side than the vertical axis has been widely spread (refer to JP2002). -220060A). In such a stroller, when the handle is in the back push position, the operator (protector) can hold the handle from the back side of the infant. Moreover, the operator can push the stroller forward by the infant facing the direction of travel. On the other hand, when the handle is in the facing push position, the operator can grasp the handle from the front side of the foot facing the infant. Further, the operator can push the stroller forward in the forward direction of the forward side.

然而，有時嬰兒車也會在有落差的行進面上行進。此時，為了要越過落差，必須使相對於行進方向位在前方的車輪浮起。圖8中，示意地顯示越過落差的動作。如圖8所示，越過落差時，通常是將把手503往下方壓下，而使嬰兒車501產生力矩。藉此，以相對於行進方向位在後方的車輪515為基準，使整個嬰兒車501相對於鉛直方向朝後方傾斜。然後，使相對於行進方向位在前方的車輪517浮起。 However, sometimes the stroller will travel on the running surface where there is a drop. At this time, in order to cross the drop, it must be placed in front of the direction of travel. The wheels float. In Fig. 8, the action of crossing the drop is schematically shown. As shown in Fig. 8, when the drop is exceeded, the handle 503 is usually pressed downward to cause the stroller 501 to generate a moment. Thereby, the entire stroller 501 is inclined rearward with respect to the vertical direction with respect to the wheel 515 positioned rearward with respect to the traveling direction. Then, the wheel 517 which is positioned forward with respect to the traveling direction is floated.

發明概要 Summary of invention

然而，如圖8所示，握持把手503的部分、與作為旋轉起點之相對於行進方向位在後方之車輪515的旋轉中心515a，在前後方向上之距離D51通常會變短。相對於此，嬰幼兒之重心G、與成為旋轉起點之位在後方之車輪515的旋轉中心515a，在前後方向上之距離D52通常會變長。因此，即使壓下把手503，也無法以相對於行進方向位在後方之車輪515為基準，而有效率地產生使整個嬰兒車501朝後方旋轉的力量。結果，就無法使位於前方之車輪517輕易地浮起。 However, as shown in FIG. 8, the distance D51 in the front-rear direction is generally shortened in the front-rear direction of the portion of the holding handle 503 and the rotation center 515a of the wheel 515 which is positioned rearward with respect to the traveling direction as the starting point of rotation. On the other hand, the center of gravity G of the infant and the center of rotation 515a of the wheel 515 which is the starting point of the rotation are generally longer than the distance D52 in the front-rear direction. Therefore, even if the handle 503 is pressed, the force that rotates the entire stroller 501 toward the rear can be efficiently generated with reference to the wheel 515 positioned rearward with respect to the traveling direction. As a result, the front wheel 517 cannot be easily floated.

本發明是考慮了以上之點而作成者，其目的在於提供一種當以面對嬰幼兒的狀態行進時可輕易將位於行進方向前方之車輪抬起的嬰兒車。 The present invention has been made in consideration of the above points, and an object thereof is to provide a stroller that can easily lift a wheel that is located in front of a traveling direction when traveling in a state of facing an infant.

用以實施發明之形態 Form for implementing the invention

以下參照圖面說明本發明之一實施形態。圖1~圖7是用於說明本發明之嬰兒車之一實施形態的圖。其中，圖1及圖2顯示了嬰兒車1的整體構成。圖1及圖2所示之嬰兒車1，具備框架本體2、及把手3。其中，框架本體2具有：分別配置於左右之一對前腳11、分別配置於左右之一對後腳12、以及分別配置於左右之一對扶手13。 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 7 are views for explaining an embodiment of a stroller of the present invention. 1 and 2 show the overall configuration of the stroller 1. The stroller 1 shown in Figs. 1 and 2 includes a frame body 2 and a handle 3. The frame body 2 has a pair of left and right front legs 11 , one pair of left and right rear legs 12 , and one pair of right and left handrails 13 .

前腳11之下端，安裝有輪子14。如圖1所示，安裝於前腳11之輪子14以旋轉中心線15a為中心可旋轉地保持前輪15。此外，輪子14以與旋轉中心線15a正交之輪軸線 14a為中心，而使前輪15可旋轉。另一方面，後腳12之下端安裝有車輪保持體16。車輪保持體16是使後輪17的方向保持一定並以旋轉中心線17a為中心可旋轉地保持該後輪17。 At the lower end of the forefoot 11, a wheel 14 is mounted. As shown in FIG. 1, the wheel 14 attached to the front leg 11 rotatably holds the front wheel 15 centering on the rotation center line 15a. In addition, the wheel 14 is oriented with a wheel axis orthogonal to the centerline of rotation 15a. 14a is centered, and the front wheel 15 is rotatable. On the other hand, the wheel holding body 16 is attached to the lower end of the rear leg 12. The wheel holding body 16 keeps the direction of the rear wheel 17 constant and rotatably holds the rear wheel 17 around the rotation center line 17a.

並且，前腳11之上端部分可轉動(可搖動)地連接於分別配置在對應側(左側或右側)之扶手13的前方部分。同樣地，後腳12之上端部分可轉動(可搖動)地連接於分別配置在對應側(左側或右側)之扶手13的前方部分。 Further, the upper end portion of the front leg 11 is rotatably (tiltable) connected to the front portion of the armrest 13 respectively disposed on the corresponding side (left side or right side). Similarly, the upper end portion of the rear leg 12 is rotatably (tiltable) coupled to the front portion of the armrest 13 respectively disposed on the corresponding side (left side or right side).

把手3透過軸構件4可搖動地連接如此的框架本體2。如圖1所示，把手3具有整體呈U字形的形狀。本實施形態中，把手3包含：相互成略平行而延伸之略直線狀的一對把手延伸部3a；及連結一對把手延伸部3a之間的把手連結部(握持部)3b。嬰兒車1之操作者握持把手連結部3b以操縱該當嬰兒車1。 The handle 3 is rotatably coupled to the frame body 2 through the shaft member 4. As shown in Fig. 1, the handle 3 has an overall U-shape. In the present embodiment, the handle 3 includes a pair of handle extending portions 3a that are slightly linearly extending in parallel with each other, and a handle connecting portion (holding portion) 3b that connects between the pair of handle extending portions 3a. The operator of the stroller 1 grips the handle joint 3b to manipulate the stroller 1.

把手3構成為能夠在圖2中以兩點鏈線所示之背面推動位置P1、及圖2中以實線所示之面對推動位置P2上可釋放地固定。在背面推動位置P1，由側面觀察，把手3對鉛直軸傾斜而使把手3之上方部分位於後方。此時，操作者(保護者)會成為由嬰幼兒之背面側握持把手3。並且，操作者使嬰幼兒面朝行進方向之前方而使嬰兒車1行進(圖1的狀態及圖2以兩點鏈線所示的狀態)。另一方面，在面對推動位置P2，由側面觀察，把手3對鉛直軸傾斜而使把手3之上方部分位於前方。此時，操作者(保護者)會成為由面對嬰幼兒之前腳11側的位置握持把手3。而且，操作者使嬰兒車1 之後腳12側成為行進方向之前方而使嬰兒車1行進(圖2以實線所示之狀態)。 The handle 3 is configured to be releasably fixable in the back push position P1 shown by the two-dot chain line in FIG. 2 and the facing push position P2 shown by the solid line in FIG. At the rear push position P1, the handle 3 is inclined to the vertical axis and the upper portion of the handle 3 is located rearward as viewed from the side. At this time, the operator (protector) will hold the handle 3 from the back side of the infant. Further, the operator causes the baby carriage 1 to travel in front of the traveling direction (the state of FIG. 1 and the state shown by the two-dot chain line in FIG. 2). On the other hand, when facing the push position P2, the handle 3 is inclined to the vertical axis and the upper portion of the handle 3 is located forward as viewed from the side. At this time, the operator (protector) will hold the handle 3 by the position facing the infant's front foot 11 side. Moreover, the operator makes the stroller 1 Thereafter, the side of the leg 12 is in front of the traveling direction, and the stroller 1 is advanced (the state shown by the solid line in Fig. 2).

再者，使把手3可對框架本體2搖動的構成可採用已知之構成，例如JP2008-254688A中所揭示之構成。因此，本說明書中，省略了更詳細的說明。 Further, a configuration in which the handle 3 can swing the frame body 2 can be constituted by a known configuration, for example, as disclosed in JP2008-254688A. Therefore, in the present specification, a more detailed description is omitted.

又，本實施形態中，嬰兒車1如目前廣為普及地構成為可折疊。可將嬰兒車1摺疊之構成可採用已知之構成，例如上述JP2008-254688A中所揭示之構成。因此，本說明書中，省略了更詳細的說明。 Further, in the present embodiment, the stroller 1 is configured to be foldable as it is currently widely used. The configuration in which the stroller 1 can be folded can be constituted by a known configuration, such as the one disclosed in JP 2008-254688 A. Therefore, in the present specification, a more detailed description is omitted.

此處，在本說明書中，對於嬰兒車及其構成要素中所使用之「前」、「後」、「上」、「下」、「前後方向」，及「上下方向」之用語，若沒有特別指示，則意指以乘坐於展開狀態下之嬰兒車1的嬰幼兒為基準的「前」、「後」、「上」、「下」、「前後方向」、及「上下方向」。更詳細言之，所謂嬰兒車1之「前後方向」，是在圖1中連結紙面之左下和右上的方向，相當於圖2中之紙面的左右方向。而且，只要沒有特別指示，所謂的「前」，指的是乘車之嬰幼兒面向的側，圖1中之紙面的左下側及圖2中之紙面的左側為嬰兒車1之前側。另一方面，所謂嬰兒車1之「上下方向」，是意指與前後方向正交且與接地面正交的方向。又，接地面為水平面時，「上下方向」指的是垂直方向。又，所謂「寬度方向」意指橫向，即與「前後方向」及「上下方向」之任一者正交的方向。 Here, in this specification, the terms "front", "back", "upper", "lower", "front and rear direction", and "up and down direction" used in the stroller and its components are not included. The special instructions mean "front", "back", "upper", "lower", "front and rear direction", and "up and down direction" based on the infants of the stroller 1 in the deployed state. More specifically, the "front-rear direction" of the stroller 1 is a direction in which the left and right sides of the paper surface are connected in FIG. 1, and corresponds to the left-right direction of the paper surface in FIG. Further, unless otherwise specified, the term "front" refers to the side of the infant facing the vehicle, and the left lower side of the paper surface in Fig. 1 and the left side of the paper surface in Fig. 2 are the front side of the stroller 1. On the other hand, the "up and down direction" of the stroller 1 means a direction orthogonal to the front-rear direction and orthogonal to the ground plane. When the ground plane is a horizontal plane, the "up and down direction" refers to the vertical direction. In addition, the "width direction" means a horizontal direction, that is, a direction orthogonal to any of the "front-rear direction" and the "up-and-down direction".

進而，本實施形態之嬰兒車1的框架本體2在一對前腳11之間具有前方連結構件20。前方連結構件20設置為連結一對前腳11，以提高框架本體2之剛性。圖3放大顯示前方連結構件20。如圖3所示，前方連結構件20是由具有在嬰兒車1之寬度方向上延伸之長邊方向X的軸狀構件所構成。前方連結構件20包含：與上下方向相對之頂面21及底面25、及與前後方向相對之前面28及後面29。具體而言，頂面21、底面25、前面28及後面29分別面向上方、下方、前方及後方。 Further, the frame main body 2 of the stroller 1 of the present embodiment has the front connecting member 20 between the pair of front legs 11. The front connecting member 20 is set to A pair of front legs 11 are coupled to increase the rigidity of the frame body 2. FIG. 3 shows the front connecting member 20 in an enlarged manner. As shown in FIG. 3, the front connecting member 20 is constituted by a shaft-shaped member having a longitudinal direction X extending in the width direction of the stroller 1. The front connecting member 20 includes a top surface 21 and a bottom surface 25 that face the vertical direction, and a front surface 28 and a rear surface 29 that face the front-rear direction. Specifically, the top surface 21, the bottom surface 25, the front surface 28, and the rear surface 29 face upward, downward, front, and rear, respectively.

前方連結構件20之頂面21包含：往後方並向上方傾斜之腳踏面22、及大略沿著水平方向延伸擴展的平面21a。腳踏面22是當把手3位於面對推動位置P2時，用以使位於行進方向前方之後輪17浮起。具體而言，腳踏面22是當操作者面對嬰幼兒而使嬰兒車1行進時，讓操作者放腳以使位於行進方向前方之後輪17浮起的部分。 The top surface 21 of the front connecting member 20 includes a tread surface 22 that is inclined rearward and upward, and a flat surface 21a that extends substantially in the horizontal direction. The tread surface 22 is such that when the handle 3 is located facing the push position P2, the wheel 17 is floated after the front side in the traveling direction. Specifically, the tread surface 22 is a portion that allows the operator to put his or her feet on the front side in the traveling direction to float the wheel 17 when the operator faces the infant.

如圖3所示，腳踏面22位於前方連結構件20之長邊方向X的中央。平面21a延伸擴展於前方連結構件20之長邊方向X上成為腳踏面22之兩側的位置。 As shown in FIG. 3, the tread surface 22 is located in the center of the longitudinal direction X of the front connection member 20. The plane 21a extends and expands at a position on both sides of the tread surface 22 in the longitudinal direction X of the front connecting member 20.

圖4及圖5中，分別放大顯示了腳踏面22及平面21a之剖面。如圖4所示，腳踏面22往後方(圖4中右方)並朝上方傾斜。亦即，腳踏面22在前後方向上由前側越往後側高度越高。另一方面，如圖5所示，平面21a相對於水平面稍微傾斜。因此，平面21a對水平面所形成之角度θ 1的大小變得小於腳踏面22對水平面所形成之角度θ 2(圖4)的大小。再者，圖示之例中，平面21a及腳踏面22並沒有形成為平面。此時，圖5中，所謂平面21a與水平面所形成之角度 θ 1，意指在與前方連結構件20之長邊方向X正交之剖面上，連結平面21a之前端21a1和後端21a2之直線與水平面所形成之角度。同樣地，圖4中，所謂腳踏面22與水平面所形成之角度θ 2，意指在與前方連結構件20之長邊方向X正交之剖面上，連結腳踏面22之前端22a和後端22b之直線與水平面所形成之角度。 In Fig. 4 and Fig. 5, the cross sections of the tread surface 22 and the plane 21a are shown enlarged. As shown in FIG. 4, the tread surface 22 is inclined to the rear (right side in FIG. 4) and upward. That is, the height of the tread surface 22 from the front side to the rear side in the front-rear direction is higher. On the other hand, as shown in Fig. 5, the plane 21a is slightly inclined with respect to the horizontal plane. Therefore, the magnitude of the angle θ 1 formed by the plane 21a with respect to the horizontal plane becomes smaller than the angle θ 2 (Fig. 4) formed by the tread surface 22 with respect to the horizontal plane. Further, in the illustrated example, the flat surface 21a and the tread surface 22 are not formed into a flat surface. At this time, in Fig. 5, the angle formed by the plane 21a and the horizontal plane Θ1 means an angle formed by a line connecting the front end 21a1 and the rear end 21a2 of the plane 21a to the horizontal plane in a cross section orthogonal to the longitudinal direction X of the front connecting member 20. Similarly, in Fig. 4, the angle θ 2 formed by the tread surface 22 and the horizontal plane means that the front end 22a and the rear side of the tread surface 22 are joined in a cross section orthogonal to the longitudinal direction X of the front connecting member 20. The angle formed by the line of end 22b and the horizontal plane.

圖4所示之例中，在將嬰兒車1設置於接地面的狀態下，腳踏面22相對於水平方向及鉛直方向兩者皆為傾斜。作為一例，在圖4之剖面中，將對於腳踏面22上之各位置畫上切線時，各切線與水平面所形成之角度被設定於30°以上70°以下的範圍內。 In the example shown in FIG. 4, in the state in which the stroller 1 is placed on the ground contact surface, the tread surface 22 is inclined with respect to both the horizontal direction and the vertical direction. As an example, in the cross section of FIG. 4, when the respective positions on the tread surface 22 are tangent, the angle formed by each of the tangent lines and the horizontal plane is set to be in the range of 30° or more and 70° or less.

進而，如圖3所示，腳踏面22之後端22b較平面21a更***。因此，腳踏面22之後端22b在與平面21a之間會形成落差S。另一方面，如圖3所示，腳踏面22之前端22a平順地與平面21a相連。亦即，腳踏面22之前端22a，不形成落差而與平面21a相連。腳踏面22之前端22a和後端22b之間所形成之區域，可以在與平面21a之間形成落差，也可以不形成落差而與平面21a相連。圖示之例中，較腳踏面22之前端22a後方的部分在與平面21a之間形成有落差。 Further, as shown in FIG. 3, the rear end 22b of the tread surface 22 is raised more than the flat surface 21a. Therefore, the rear end 22b of the tread surface 22 forms a drop S between it and the plane 21a. On the other hand, as shown in Fig. 3, the front end 22a of the tread surface 22 is smoothly connected to the flat surface 21a. That is, the front end 22a of the tread surface 22 is connected to the flat surface 21a without forming a drop. The region formed between the front end 22a and the rear end 22b of the tread surface 22 may be formed with a drop from the flat surface 21a or may be connected to the flat surface 21a without forming a drop. In the illustrated example, a portion of the portion behind the front end 22a of the tread surface 22 is formed with a difference from the plane 21a.

圖示之例中，腳踏面22和前述後面29之間配置有傾斜面21b(參照圖4)。而且，藉由此傾斜面21b與腳踏面22與平面21a而形成頂面21。圖4所示之傾斜面21b是面向後方朝下方傾斜。 In the illustrated example, an inclined surface 21b (see FIG. 4) is disposed between the tread surface 22 and the rear surface 29. Further, the top surface 21 is formed by the inclined surface 21b and the tread surface 22 and the flat surface 21a. The inclined surface 21b shown in Fig. 4 is inclined downward toward the rear.

又，如圖3所示，作為前方連結構件20在長邊方向X之長度的腳踏面22之寬度W1是後方比前方窄。本實施形態中，腳踏面22之寬度W1是在前後方向上由前側越往後側，階段性或連續性地越變越狹窄。作為一例，這種腳踏面22之寬度W1是配合操作者之腳的寬度而設定為約30mm~200mm之間。 Moreover, as shown in FIG. 3, the front connecting member 20 is on the long side. The width W1 of the tread surface 22 having a length of X is narrower toward the rear than the front. In the present embodiment, the width W1 of the tread surface 22 is gradually narrower from the front side to the rear side in the front-rear direction. As an example, the width W1 of the tread surface 22 is set to be between about 30 mm and 200 mm in accordance with the width of the operator's foot.

在此，參照圖6再說明腳踏面22和前腳11之配置關係。圖6是由前方連結構件20之長邊方向X觀察圖4所示之剖面的圖，也圖示有前腳11。腳踏面22之前端22a由圖6所示之方向觀察時，位於較前腳11更前方(圖6中左方)處。又，腳踏面22之前端22a位於較前輪15之旋轉中心線15a更後方(圖6中右方)處。再者，此處所謂之前輪15之旋轉中心線15a的位置，是意指前輪15繞著輪子14之輪軸線14a旋轉，而使前輪15之旋轉中心線15a位於最前方(圖6中左方)時的位置。 Here, the arrangement relationship between the tread surface 22 and the front leg 11 will be described with reference to Fig. 6 . FIG. 6 is a cross-sectional view of FIG. 4 viewed from the longitudinal direction X of the front connecting member 20, and also shows the forefoot 11. When the front end 22a of the tread surface 22 is viewed from the direction shown in Fig. 6, it is located further forward than the front leg 11 (left side in Fig. 6). Further, the front end 22a of the tread surface 22 is located further rearward than the rotation center line 15a of the front wheel 15 (right side in Fig. 6). Further, the position of the rotation center line 15a of the front wheel 15 herein means that the front wheel 15 rotates about the wheel axis 14a of the wheel 14, and the rotation center line 15a of the front wheel 15 is located at the forefront (left side in Fig. 6). ) The location of the time.

另一方面，腳踏面22之後端22b在由圖6所示之方向觀察時，是位於與前腳11重疊的位置上。作為一例，這樣的腳踏面22之前端22a和後端22b之間在前後方向上的長度形成為約30mm~50mm。 On the other hand, the rear end 22b of the tread surface 22 is located at a position overlapping the front leg 11 when viewed in the direction shown in FIG. As an example, the length between the front end 22a and the rear end 22b of the tread surface 22 in the front-rear direction is formed to be about 30 mm to 50 mm.

回到圖3，沿著一個方向延伸之複數根凸條部23在前後方向上有間隔地形成於腳踏面22。凸條部23具有當操作者的腳放置於腳踏面22時，抑制操作者的腳由腳踏面22滑落的功能。本實施形態中，配置於腳踏面22之各凸條部23之長邊方向，與前方連結構件20之長邊方向X成平行。由於操作者之腳的力量是朝行進方向之後方而往下方施加，因此當各凸條部23之長邊方向與前方連結構件20之長邊方向X成平行時，對於操作者之腳在腳踏面22上施力的方向，配置於腳踏面22之凸條部23可發揮優越的止滑效果。再者，圖3所示之例中，作為腳踏面22之止滑功能是顯示了在腳踏面22配置有複數根凸條部23之例，但並不限定於此種例子。作為腳踏面22之止滑功能，也可在腳踏面22形成溝來取代凸條部23。 Referring back to FIG. 3, a plurality of ridge portions 23 extending in one direction are formed at intervals on the tread surface 22 in the front-rear direction. The ridge portion 23 has a function of suppressing the operator's foot from sliding off the tread surface 22 when the operator's foot is placed on the tread surface 22. In the present embodiment, the longitudinal direction of each of the ridge portions 23 of the tread surface 22 is parallel to the longitudinal direction X of the front connecting member 20. Since the force of the operator's foot is applied to the rear of the direction of travel, Therefore, when the longitudinal direction of each of the ridge portions 23 is parallel to the longitudinal direction X of the front connecting member 20, the ridges of the tread surface 22 are arranged in the direction in which the operator's feet are biased on the tread surface 22. The portion 23 can exert a superior anti-slip effect. In the example shown in FIG. 3, the slip preventing function of the tread surface 22 is an example in which a plurality of ridge portions 23 are disposed on the tread surface 22, but the present invention is not limited to such an example. As the anti-slip function of the tread surface 22, a groove may be formed in the tread surface 22 instead of the ridge portion 23.

又，如圖3所示，前方連結構件20之腳踏面22的兩側，形成有用以支撐乘坐於嬰兒車1的嬰幼兒之腳的置腳面24。亦即，腳踏面22位於一對置腳面24之間。此置腳面24是形成平面21a的一部分。在置腳面24設置有相互分開配置之複數個突出部24a。複數個突出部24a由上方觀察具有略呈圓形的形狀。此突出部24a是當嬰幼兒的腳放置於置腳面24時，可抑制嬰幼兒的腳由置腳部24滑落。 Further, as shown in FIG. 3, on both sides of the tread surface 22 of the front connecting member 20, a footrest surface 24 for supporting the foot of the infant who is seated on the stroller 1 is formed. That is, the tread surface 22 is located between the pair of foot surfaces 24. This foot surface 24 is part of the formation plane 21a. The footrest surface 24 is provided with a plurality of protruding portions 24a which are disposed apart from each other. The plurality of projections 24a have a slightly circular shape as viewed from above. When the foot of the infant is placed on the footrest surface 24, the protruding portion 24a can suppress the foot of the infant from slipping off by the leg portion 24.

其次，參照圖7說明前方連結構件20之底面25。圖7是前方連結構件20之底面圖。如圖7所示，在前方連結構件20之底面25設置有複數根肋部26。各肋部26在上下方向上朝下方突出。各肋部26由前方連結構件20之底面25的正面方向觀察時，具有長尺狀的形狀。藉由將此複數根肋部26設置於前方連結構件20之底面25，可以抑制因操作者之腳施加的力量所造成之腳踏面22的變形。特別是，從對腳踏面22之變形顯示了有效之耐久性的觀點來看，肋部26在底面25中，宜設置於至少有面對腳踏面22的區域25a。本實施形態中，肋部26是橫跨底面25的整個區域上以格子狀的圖案排列。 Next, the bottom surface 25 of the front connecting member 20 will be described with reference to Fig. 7 . FIG. 7 is a bottom view of the front connecting member 20. As shown in FIG. 7, a plurality of ribs 26 are provided on the bottom surface 25 of the front connecting member 20. Each of the ribs 26 protrudes downward in the vertical direction. Each of the ribs 26 has a long-shaped shape when viewed from the front direction of the bottom surface 25 of the front connecting member 20. By providing the plurality of ribs 26 on the bottom surface 25 of the front connecting member 20, deformation of the tread surface 22 due to the force applied by the operator's foot can be suppressed. In particular, from the viewpoint that the deformation of the tread surface 22 shows effective durability, the rib portion 26 is preferably provided in the bottom surface 25 in the region 25a at least facing the tread surface 22. In the present embodiment, the ribs 26 are lattice-like over the entire area of the bottom surface 25. The arrangement of the patterns.

具體而言，圖7中，沿著前方連結構件20之長邊方向X排列的複數根第1肋部26a、及與第1肋部26a交錯而沿著前述長邊方向X排列之複數根第2肋部26b排成格子狀。各第1肋部26a對連結前後方向之直線L1朝一邊側傾斜，各第2肋部26b對連結前後方向之直線L1則朝另一邊側傾斜。 Specifically, in FIG. 7, a plurality of first rib portions 26a arranged along the longitudinal direction X of the front connecting member 20 and a plurality of first rib portions 26a interlaced with the first rib portions 26a and arranged along the longitudinal direction X The ribs 26b are arranged in a lattice shape. Each of the first ribs 26a is inclined toward the one side with respect to the straight line L1 connecting the front-rear direction, and each of the second ribs 26b is inclined toward the other side with respect to the straight line L1 connecting the front-rear direction.

透過以格子狀之圖案排列之複數根肋部26而劃分出複數個凹孔部27。亦即，凹孔部27是在被複數根肋部26至少局部包圍之空間內劃分而成。在設置凹孔部27之位置上的前方連結構件20的厚度，比設置肋部26之位置上的前方連結構件20的厚度薄。藉由在前方連結構件20上設置有凹孔部27，可以減輕前方連結構件20的重量。 A plurality of recessed holes 27 are defined by a plurality of ribs 26 arranged in a lattice pattern. That is, the recessed portion 27 is defined in a space that is at least partially surrounded by the plurality of ribs 26. The thickness of the front connecting member 20 at the position where the recessed hole portion 27 is provided is thinner than the thickness of the front connecting member 20 at the position where the rib portion 26 is provided. By providing the recessed portion 27 in the front connecting member 20, the weight of the front connecting member 20 can be reduced.

但，肋部26之排列圖案及凹孔部27之形狀僅為一例，並不限定於圖7所示之例。作為其他例，例如，肋部26之排列圖案亦可決定為使凹孔部27在從圖7所示之方向觀察時成圓形或橢圓形。或者是，肋部26也可以排列成千鳥狀的圖案。 However, the arrangement pattern of the ribs 26 and the shape of the recessed portion 27 are merely examples, and are not limited to the example shown in FIG. As another example, for example, the arrangement pattern of the ribs 26 may be determined such that the recessed portions 27 are circular or elliptical when viewed from the direction shown in FIG. Alternatively, the ribs 26 may be arranged in a pattern of a thousand birds.

如上述之腳踏面22、肋部26及凹孔部27所形成之前方連結構件20，作為一例，可藉由將樹脂材料成形為預定的形狀來製作。此種情況下，前方連結構件20是由單一之構件所構成，因此，肋部26是與組成前方連結構件20之其他的構成要素成形為一體。 The front connecting member 20 formed by the tread surface 22, the rib portion 26, and the recessed portion 27 as described above can be produced by molding a resin material into a predetermined shape as an example. In this case, since the front connecting member 20 is composed of a single member, the rib 26 is integrally formed with other constituent elements constituting the front connecting member 20.

其次，針對如以上之構成所組成之本實施形態的作用進行說明。 Next, the operation of the present embodiment constituted by the above configuration will be described.

在把手3配置於面對推動位置P2之圖2所示的狀態中，操作者是從面對嬰幼兒之前腳11側來握持把手3。而且，操作者使嬰兒車1之後腳12側成為行進方向之前方而使嬰兒車1行進。嬰兒車1行進之行進面有時會有落差存在。此時，為使嬰兒車1可以順暢地行進，必須積極地使相對於行進方向位在前方之車輪17浮起以越過落差。 In the state shown in FIG. 2 in which the handle 3 is disposed facing the push position P2, the operator holds the handle 3 from the side of the front foot 11 facing the infant. Further, the operator causes the stroller 1 to travel after the stroller 1 has the foot 12 side in the forward direction. There is sometimes a drop in the running surface of the stroller 1 traveling. At this time, in order for the stroller 1 to smoothly travel, it is necessary to actively float the wheel 17 positioned forward with respect to the traveling direction to overcome the drop.

具體而言，以腳將前方連結構件20之腳踏面22朝行進方向的前方往下方踩壓，而使成為基準之相對於行進方向位在後方的車輪15踩壓於接地面上而使其難以活動。接著，以手將把手3之把手連結部3b朝下方壓下，以使嬰兒車1產生力矩。藉此，可以難以活動之相對於行進方向位在後方之車輪15為基準，使整個嬰兒車1相對於鉛直方向朝後方傾斜，而使相對於行進方向位在前方的車輪17輕易浮起。 Specifically, the tread surface 22 of the front connecting member 20 is pressed downward toward the front in the traveling direction by the foot, and the wheel 15 positioned as the reference with respect to the traveling direction is pressed against the ground surface. Hard to move. Next, the handle connecting portion 3b of the handle 3 is pressed downward by hand to cause the stroller 1 to generate a moment. Thereby, it is possible to make the entire stroller 1 tilt rearward with respect to the vertical direction with respect to the rear wheel 15 with respect to the traveling direction, and to easily float the wheel 17 positioned forward with respect to the traveling direction.

如上述，根據本實施形態，在配置於一對前腳11之間的前方連結構件20的表面，設置有往後方並向上方傾斜之腳踏面22。根據這樣的形態，在把手3配置於面對推動位置P2之狀態下，首先，以腳將前方連結構件20之腳踏面22往下方踩壓，而使成為基準之相對於行進方向位在後方的車輪15踩壓於接地面上而使其難以活動。接著，以手將把手3朝下方壓下，使嬰兒車1產生力矩。藉此，可以難以活動之相對於行進方向位在後方之車輪15為基準，使整個嬰兒車1相對於鉛直方向朝後方傾斜，而使相對於行進方向位在前方的車輪17輕易浮起。又，操作者從握持著位於面對推動位置P2的把手3並推動嬰兒車1前進的狀態，能夠以毫不勉強的姿勢輕易地進行以腳踩壓腳踏面22的動作、以及以手將把手3朝下方下壓的動作。這些結果是，在把手3配置於面對推動位置P2的狀態下，可以使相對於行進方向位在前方的車輪17輕易地浮起。 As described above, according to the present embodiment, the front surface of the front connecting member 20 disposed between the pair of front legs 11 is provided with a tread surface 22 that is inclined rearward and upward. According to this aspect, in a state where the handle 3 is disposed to face the push position P2, first, the tread surface 22 of the front connecting member 20 is pressed downward by the foot, and the reference is positioned rearward with respect to the traveling direction. The wheel 15 is pressed against the ground plane to make it difficult to move. Next, the handle 3 is pressed downward by hand to cause the stroller 1 to generate a moment. Thereby, it is possible to make the entire stroller 1 tilt rearward with respect to the vertical direction with respect to the rear wheel 15 with respect to the traveling direction, and to easily float the wheel 17 positioned forward with respect to the traveling direction. Again, the operator is holding the face When the handle 3 of the position P2 is pushed and the stroller 1 is pushed forward, the operation of pressing the tread surface 22 with the foot and pressing the handle 3 downward with the hand can be easily performed in a posture that is not reluctant. As a result, in a state where the handle 3 is disposed to face the push position P2, the wheel 17 positioned forward with respect to the traveling direction can be easily floated.

又，根據本實施形態，腳踏面22位於前方連結構件20之長邊方向X的中央。此種情況下，以腳踩壓腳踏面22時，因為可以使相對於行進方向位在後方的2個車輪15平穩地踩壓在接地面，因此能夠以相對於行進方向位在後方之車輪15為基準，使整個嬰兒車1平穩地相對於鉛直方向朝行進方向的後方傾斜。結果，有助於使相對於行進方向位在前方之車輪17穩定地浮起。 Moreover, according to this embodiment, the tread surface 22 is located in the center of the longitudinal direction X of the front connection member 20. In this case, when the foot surface 22 is pressed by the foot, since the two wheels 15 positioned rearward with respect to the traveling direction can be smoothly pressed against the ground contact surface, the wheel can be positioned rearward with respect to the traveling direction. 15 is the reference, so that the entire stroller 1 is smoothly tilted rearward in the traveling direction with respect to the vertical direction. As a result, it is helpful to stably float the wheel 17 positioned forward with respect to the traveling direction.

又，根據本實施形態，在前方連結構件20之頂面21中，在前方連結構件20之長邊方向X上位於腳踏面22之兩側的區域21a之相對於水平面的傾斜角度θ 1，比腳踏面22之相對於水平面的傾斜角度θ 2小。此時，腳踏面22較頂面21中之其他區域21a更容易放置操作者的腳部，而且因為穩定也可以輕易地施力。 Further, according to the present embodiment, in the top surface 21 of the front connecting member 20, the inclination angle θ 1 with respect to the horizontal plane of the region 21a on both sides of the tread surface 22 in the longitudinal direction X of the front connecting member 20 is obtained. It is smaller than the inclination angle θ 2 of the tread surface 22 with respect to the horizontal plane. At this time, the tread surface 22 is easier to place the operator's foot than the other area 21a in the top surface 21, and the force can be easily applied because of the stability.

又，根據本實施形態，腳踏面22與水平面所形成之角度設定於30°以上70°以下。此時，操作者的腳可以容易地放置於腳踏面22，並且，也有助於平穩地對腳踏面22施力。 Further, according to the present embodiment, the angle formed by the tread surface 22 and the horizontal plane is set to be 30 or more and 70 or less. At this time, the operator's foot can be easily placed on the tread surface 22, and also contributes to the smooth application of the tread surface 22.

又，根據本實施形態，腳踏面22之寬度W1是後方比前方窄。此種情況下，由於腳踏面22之前方的寬度相對地較寬，因此操作者的腳可以輕易地到達腳踏面22上。另一方面，因為腳踏面22之後方的寬度相對地較窄，因此有助於抑制踩壓腳踏面22之位置的偏差。因此，根據這樣的形態，操作者的腳可以容易地放置於腳踏面22上，並且，可使相對於行進方向位在後方的車輪17穩定地踩壓於接地面。從有效地發揮此種功能的觀點來看，較理想的是，腳踏面22之寬度W1從前後方向上的前側越朝後側越狹窄。 Further, according to the present embodiment, the width W1 of the tread surface 22 is narrower toward the rear than the front. In this case, due to the width of the front side of the tread 22 The ground is wider so that the operator's feet can easily reach the tread surface 22. On the other hand, since the width behind the tread surface 22 is relatively narrow, it is advantageous in suppressing the deviation of the position of the tread surface 22 to be pressed. Therefore, according to such an aspect, the operator's foot can be easily placed on the tread surface 22, and the wheel 17 positioned rearward with respect to the traveling direction can be stably pressed against the ground contact surface. From the viewpoint of effectively exerting such a function, it is preferable that the width W1 of the tread surface 22 is narrower toward the rear side from the front side in the front-rear direction.

又，根據本實施形態，腳踏面22之前端22a由前方連結構件20之長邊方向X觀察時，會比前腳11更朝前方延伸出(圖6中左方)。根據此種腳踏面22之配置，有助於使操作者的腳容易到達腳踏面22。除此之外，腳踏面22之前端22a位於比前輪15之旋轉中心線15a更後方。因此，在嬰兒車1的搬運等時，可減低腳踏面22之前端22a接觸其他之構造物的狀況。 Further, according to the present embodiment, when the front end 22a of the tread surface 22 is viewed from the longitudinal direction X of the front connecting member 20, it extends further forward than the front leg 11 (left side in Fig. 6). According to the arrangement of the tread surface 22, it is easy to make the operator's foot easily reach the tread surface 22. In addition to this, the front end 22a of the tread surface 22 is located rearward of the rotation center line 15a of the front wheel 15. Therefore, when the stroller 1 is transported or the like, the situation in which the front end 22a of the tread surface 22 contacts other structures can be reduced.

又，根據本實施形態，腳踏面22之後端22b由前方連結構件20之長邊方向X觀察時，位於與前腳11重疊的位置上(參照圖6)。根據此種腳踏面22之配置在腳踏面22、與在面對推動位置操作嬰兒車之操作者的腳之間，在前後方向上形成適當的間隔。因此，有助於操作者之腳部可以在毫不勉強的姿勢下放置於腳踏面22上。 Further, according to the present embodiment, when the rear end 22b of the tread surface 22 is viewed from the longitudinal direction X of the front connecting member 20, it is located at a position overlapping the front leg 11 (see Fig. 6). According to the arrangement of the tread surface 22, an appropriate interval is formed in the front-rear direction between the tread surface 22 and the foot of the operator who operates the stroller at the pushing position. Therefore, the operator's foot can be placed on the tread surface 22 without any reluctance.

又，根據本實施形態，腳踏面22之後端22b透過落差S與前方連結構件20之表面的其他部分21a相連。根據此種形態，前述落差S對腳踏面22之踩壓，可發揮如肋部般的補強作用。因此，藉由形成前述落差S，有助於確保腳踏面22所需之剛性。結果，可謀求前方連結構件20之重量的減低及材料費的節約。 Further, according to the present embodiment, the rear end 22b of the tread surface 22 is connected to the other portion 21a of the front surface of the front connecting member 20 through the drop S. According to this aspect, the step S on the tread surface 22 can exert a reinforcing effect like a rib. Therefore, by forming the aforementioned drop S, it is helpful to ensure the pedal The rigidity required for face 22. As a result, the weight of the front connecting member 20 can be reduced and the material cost can be saved.

尤其是，根據本實施形態，腳踏面22之前端22a平順地與前方連結構件20之頂面21的其他部分、亦即平面21a相連，且比腳踏面22之前端22a更後方的部分、透過落差與前方連結構件20之頂面21的其他部分、亦即平面21a相連。根據此種形態，由於腳踏面22之前端22a與平面21a平順地相連，因此可大幅減低跨在前方連結構件20之前緣上之嬰幼兒的腳部勾到落差的狀況。另一方面，因為比腳踏面22之前端22a更後方的部分在平面21a及傾斜面21b之間會形成落差，因此對於操作者的腳對腳踏面22的踩壓可發揮如肋部般的補強作用。 In particular, according to the present embodiment, the front end 22a of the tread surface 22 is smoothly connected to the other portion of the top surface 21 of the front connecting member 20, that is, the flat surface 21a, and is further rearward than the front end 22a of the tread surface 22, The drop is connected to the other portion of the top surface 21 of the front connecting member 20, that is, the flat surface 21a. According to this aspect, since the front end 22a of the tread surface 22 is smoothly connected to the flat surface 21a, it is possible to greatly reduce the situation in which the foot of the infant crossing the front edge of the front connecting member 20 is hooked. On the other hand, since a portion which is rearward than the front end 22a of the tread surface 22 forms a drop between the flat surface 21a and the inclined surface 21b, the pressing force on the tread surface 22 of the operator's foot can be performed like a rib. Reinforcement.

又，根據本實施形態，在前方連結構件20之底面25上設置有複數根的肋部26，並以複數根的肋部26劃分複數個凹孔部27。根據此種形態，可有效地確保腳踏面22所需之剛性，並可同時謀求減低前方連結構件20的重量。 Further, according to the present embodiment, a plurality of ribs 26 are provided on the bottom surface 25 of the front connecting member 20, and a plurality of recessed portions 27 are defined by a plurality of ribs 26. According to this aspect, the rigidity required for the tread surface 22 can be effectively ensured, and at the same time, the weight of the front connecting member 20 can be reduced.

又，根據本實施形態，在腳踏面22設置有沿著前方連結構件20之長邊方向X延伸的複數根凸條部23。根據此種形態，可抑制操作者的腳從腳踏面22滑落。尤其是，因為各凸條部23是沿著前方連結構件20之長邊方向X延伸，所以對於操作者的腳在腳踏面22上施力的方向，形成於腳踏面22上之凸條部23可發揮優越的止滑效果。 Further, according to the present embodiment, the leg surface 22 is provided with a plurality of ridge portions 23 extending in the longitudinal direction X of the front connecting member 20. According to this aspect, it is possible to suppress the operator's foot from slipping off from the tread surface 22. In particular, since each of the ridge portions 23 extends in the longitudinal direction X of the front connecting member 20, the ridges formed on the tread surface 22 in the direction in which the operator's foot is biased on the tread surface 22 The portion 23 can exert a superior anti-slip effect.

又，根據本實施形態，腳踏面22位於一對置腳面24之間。此時，操作者將腳放置於腳踏面22的動作，不容易被嬰幼兒的腳阻礙。 Further, according to the present embodiment, the tread surface 22 is located between the pair of leg surfaces 24.
