Description

嬰兒車baby carriage

本發明是有關於一種握把在第一位置與第二位置之間可擺動的嬰兒車。 The present invention relates to a stroller with a handle swingable between a first position and a second position.

例如如專利文獻1(JP2017-81252A)所揭示般，已知一種使握把可擺動的嬰兒車。於專利文獻1所揭示的嬰兒車中，握把在背面推動位置與對面推動位置之間可擺動。於背面推動位置，握把位於嬰幼兒的背面側，監護人自嬰幼兒的背面側推動嬰兒車來使嬰兒車前進。於對面推動位置，握把位於與嬰幼兒對面的側，監護人自與嬰幼兒對面之側推動嬰兒車來使嬰兒車前進。 For example, as disclosed in Patent Document 1 (JP2017-81252A), there is known a stroller with a swingable handle. In the stroller disclosed in Patent Document 1, the handle is swingable between the rear push position and the opposite push position. In the back push position, the handle is located on the back side of the infant, and the guardian pushes the stroller from the back side of the infant to advance the stroller. In the opposite push position, the handle is located on the side opposite to the infant, and the guardian pushes the stroller from the side opposite to the infant to advance the stroller.

於握把處於背面推動位置的情況下，嬰幼兒可面向行進方向前方。於握把處於對面推動位置的情況下，監護人可一面確認嬰幼兒一面使嬰兒車行進。因此，在將低月齡嬰幼兒載置於嬰兒車時，大多將握把配置於對面推動位置，在將例如腰部已坐住的嬰幼兒載置於嬰兒車時，傾向於將握把配置於背面推動位置。 With the handle in the rear push position, the infant can face forward in the direction of travel. When the handle is in the opposite push position, the guardian can make the stroller move while confirming the infant. Therefore, when a low-month-old infant is placed on a stroller, the handle is often placed in the opposite push position, and when an infant who is sitting on the waist, for example, is placed on the stroller, the handle tends to be placed on the stroller. Back push position.

如以上所述，傾向於根據嬰幼兒的月齡而變更握把的位置。另一方面，於現有的嬰兒車中，未進行用於根據握把位置而變更嬰兒車特性的研究。例如，在將握把配置於傾向於適宜於低月齡嬰幼兒的對面推動位置的情況下，只要使嬰兒車的穩定性提高即可，另一方面，在將握把配置於與對面推動位置相比而傾向 於適宜於月齡大的嬰幼兒的背面推動位置的情況下，只要使嬰兒車的操縱性提高即可。 As described above, the position of the grip tends to be changed according to the age of the infant. On the other hand, in the conventional stroller, no study has been conducted to change the characteristics of the stroller according to the grip position. For example, in the case where the handle is arranged in the opposite pushing position which tends to be suitable for infants of young age, it is sufficient to improve the stability of the stroller. On the other hand, when the handle is arranged at the opposite pushing position tend to compare When it is suitable for the back push position of a month old infant, it is sufficient to improve the maneuverability of the stroller.

For example, the holding body 42 that moves upward against the urging force of the urging member moves downward so as to cover the first position holding member 36 or the second position holding member 37 , whereby the holding body 42 and the first position holding member can be moved downward. 36 or the second position holding member 37 is engaged.

具有以上構成的嬰兒車本體11藉由使各構成構件相對轉動而可折疊。具體而言，將配置於第一位置的握把40暫且向後上方拉起，其後，朝下方按下，藉此使第四連桿L4相對於後腿16於圖2中朝順時針方向轉動。伴隨著所述操作，第一連桿L1及第三連桿L3相對於第二連桿L2於圖2中朝順時針方向轉動。藉由 此種操作，在側視下握把40與前腿14一面維持大致平行的配置一面相互接近，且握把40的位置下降。以如上方式，可如圖4所示般將嬰兒車本體11折疊。在圖4的已折疊的狀態下，可將嬰兒車10的沿著前後方向及上下方向的尺寸小型化。另一方面，為了將嬰兒車本體11自折疊狀態展開，執行與上文所述的折疊操作相反的程序即可。 The stroller body 11 having the above-described configuration is foldable by relatively rotating the respective constituent members. Specifically, the handle 40 disposed at the first position is once pulled up rearward and upward, and then pressed downward, whereby the fourth link L4 is rotated clockwise in FIG. 2 with respect to the rear leg 16 . . Accompanying this operation, the first link L1 and the third link L3 are rotated clockwise in FIG. 2 with respect to the second link L2. by In this operation, the grip 40 and the front leg 14 approach each other while maintaining a substantially parallel arrangement in a side view, and the position of the grip 40 is lowered. In the above manner, the stroller body 11 can be folded as shown in FIG. 4 . In the folded state of FIG. 4 , the dimensions of the stroller 10 along the front-rear direction and the vertical direction can be reduced in size. On the other hand, in order to unfold the stroller body 11 from the folded state, it is sufficient to perform the reverse procedure of the folding operation described above.

又，嬰兒車本體11具有限制兩個構成構件的相對轉動的狀態維持機構(未圖示)。藉由操作所述狀態維持機構，可進行嬰兒車本體11的折疊動作。再者，於圖示的示例中，握把40具有與狀態維持機構連結的遠距離操作裝置43。如圖1所示，遠距離操作裝置43設置於握把本體41的中間部41b。藉由操作遠距離操作裝置43而狀態維持機構運作，從而可進行嬰兒車本體11的折疊動作。 Moreover, the stroller main body 11 has a state maintaining mechanism (not shown) that restricts the relative rotation of the two constituent members. By operating the state maintaining mechanism, the baby carriage body 11 can be folded. Furthermore, in the example shown in the figure, the grip 40 has a remote operation device 43 connected to the state maintaining mechanism.

The illustrated brake member 67 is swingably supported on the second rotating body base 63 .

再者，如圖2所示，第一腳輪50具有鎖定(lock)構件58，所述鎖定構件58限制第一旋轉體52相對於第一固定體51的旋轉。所述鎖定構件58在限制位置與非限制位置之間可移動。例如，處於限制位置的鎖定構件58自第一固定體51突出而與第一旋轉體52接觸，藉此可限制第一旋轉體52相對於第一固定體51以第一腳輪軸線C1為中心的旋轉。另一方面，處於非限制位置的鎖定構件58離開第一旋轉體52，而不干擾第一旋轉體52相對於第一固定體51的旋轉運作。 Furthermore, as shown in FIG. 2 , the first caster 50 has a lock member 58 that restricts the rotation of the first rotating body 52 relative to the first fixed body 51 . The locking member 58 is movable between a restricted position and an unrestricted position. For example, the locking member 58 in the restricting position protrudes from the first fixed body 51 to contact the first rotating body 52 , thereby restricting the first rotating body 52 relative to the first fixed body 51 centered on the first caster axis C1 rotate. On the other hand, the locking member 58 in the unrestricted position is away from the first rotating body 52 without interfering with the rotational operation of the first rotating body 52 relative to the first fixed body 51 .

同樣地，如圖2所示，第二腳輪60具有鎖定構件68，所述鎖定構件68限制第二旋轉體62相對於第二固定體61的旋轉。所述鎖定構件68在限制位置與非限制位置之間可移動。例如，處於限制位置的鎖定構件68自第二固定體61突出而與第二旋轉體62接觸，藉此可限制第二旋轉體62相對於第二固定體61以第二腳輪軸線C2為中心的旋轉。另一方面，處於非限制位置的鎖定構件68離開第二旋轉體62，而不干擾第二旋轉體62相對於第二固定體61的旋轉運作。 Likewise, as shown in FIG. 2 , the second caster 60 has a locking member 68 that restricts the rotation of the second rotating body 62 relative to the second fixed body 61 . The locking member 68 is movable between a restricted position and an unrestricted position. For example, the locking member 68 in the restricting position protrudes from the second fixed body 61 to contact the second rotating body 62 , thereby restricting the second rotating body 62 relative to the second fixed body 61 centered on the second caster axis C2 rotate. On the other hand, the locking member 68 in the unrestricted position is away from the second rotating body 62 without interfering with the rotational operation of the second rotating body 62 relative to the second fixed body 61 .

進而，如圖2所示，嬰兒車本體11具有切換機構45，所述切換機構45根據握把40的位置而使鎖定構件58、鎖定構件68在限制位置與非限制位置之間移動。於圖示的示例中，切換機構45具有：切換構件46，可運作地支撐於後腿16；以及傳遞部件 47，將切換構件46及鎖定構件58、鎖定構件68之間加以連結。於圖示的示例中，切換構件46伴隨著握把40的擺動而與握把40接觸。藉由與握把40接觸，可引起切換構件46相對於後腿16的直線運作或旋轉運作等相對運作，作為具體例而可引起相對擺動動作。藉由切換構件46的運作，可經由傳遞部件47使鎖定構件58、鎖定構件68運作。 Furthermore, as shown in FIG. 2 , the stroller body 11 has a switching mechanism 45 that moves the locking member 58 and the locking member 68 between a restricted position and an unrestricted position according to the position of the handle 40 . In the illustrated example, the switching mechanism 45 has: a switching member 46 operably supported by the rear leg 16; and a transmission member 47. Connect the switching member 46, the locking member 58, and the locking member 68. In the illustrated example, the switching member 46 is brought into contact with the handle 40 as the handle 40 swings. By being in contact with the handle 40, the switching member 46 can be caused to operate relative to the rear leg 16 in a linear motion or a relative motion, such as a rotational motion, and as a specific example, a relative swing motion can be caused. By the operation of the switching member 46 , the locking member 58 and the locking member 68 can be operated through the transmission member 47 .

而且，於本實施形態中，於握把40處於第二位置的情況下限制第一腳輪50的第一旋轉體52相對於第一固定體51的旋轉。又，於握把40處於第一位置的情況下限制第二腳輪60的第二旋轉體62相對於第二固定體61的旋轉。於圖示的示例中，於握把40處於背面推動位置即第一位置(圖2所示的握把40的位置)的情況下，容許第一腳輪50的第一旋轉體52的旋轉，且限制第二腳輪60的第二旋轉體62的旋轉。另一方面，於握把40處於對面推動位置即第二位置(圖3所示的握把40的位置)的情況下，限制第一腳輪50的第一旋轉體52的旋轉，且容許第二腳輪60的第二旋轉體62的旋轉。 Furthermore, in the present embodiment, when the handle 40 is in the second position, the rotation of the first rotating body 52 of the first caster 50 with respect to the first fixed body 51 is restricted. Moreover, when the handle|steering-wheel 40 exists in a 1st position, the rotation of the 2nd rotating body 62 of the 2nd caster 60 with respect to the 2nd fixed body 61 is restricted. In the illustrated example, when the handle 40 is in the back push position, that is, the first position (the position of the handle 40 shown in FIG. 2 ), the rotation of the first rotating body 52 of the first caster 50 is allowed, and The rotation of the second rotating body 62 of the second caster 60 is restricted. On the other hand, when the handle 40 is in the opposite push position, that is, the second position (the position of the handle 40 shown in FIG. 3 ), the rotation of the first rotating body 52 of the first caster 50 is restricted, and the second position is allowed. Rotation of the second rotating body 62 of the caster 60 .

再者，切換機構45及鎖定構件58、鎖定構件68可採用各種公知的構成，例如可採用日本專利特開2008-254688號公報、日本專利特開2008-254693號公報、日本專利特開2010-234988號公報等所揭示的構成。 In addition, the switching mechanism 45, the locking member 58, and the locking member 68 may adopt various known configurations, for example, Japanese Patent Laid-Open No. 2008-254688, Japanese Patent Laid-Open No. 2008-254693, and Japanese Patent Laid-Open No. 2010- The structure disclosed in Gazette No. 234988 and the like.

其次，對包含如以上所述般的構成的嬰兒車10的作用進行說明。如上文所述般，握把40相對於本體框架12在第一位置 與第二位置之間可擺動。 Next, the operation of the stroller 10 including the above-described configuration will be described. As described above, the handle 40 is in the first position relative to the body frame 12 swingable from the second position.

在如圖2所示般將握把40配置於背面推動位置即第一位置的情況下，操作者(監護人)可自嬰幼兒的背面側握持握把40而操縱嬰兒車10，以嬰幼兒面向行進方向的前方的方式使嬰兒車10行進。此時，前腿14位於嬰兒車10的行進方向的前方，後腿16位於嬰兒車10的行進方向的後方。而且，在安裝於前腿14的第一腳輪50中，第一旋轉體52相對於第一固定體51以第一腳輪軸線C1為中心可旋轉。另一方面，在安裝於後腿16的第二腳輪60中，第二旋轉體62相對於第二固定體61以第二腳輪軸線C2為中心不可旋轉。 As shown in FIG. 2 , when the handle 40 is arranged at the back push position, that is, the first position, the operator (guardian) can hold the handle 40 from the back side of the infant to operate the stroller 10, so that the infant can operate the stroller 10. The stroller 10 is caused to travel so as to face forward in the travel direction. At this time, the front legs 14 are positioned forward in the traveling direction of the stroller 10 , and the rear legs 16 are positioned rearward in the traveling direction of the stroller 10 . Moreover, in the 1st caster 50 attached to the front leg 14, the 1st rotating body 52 is rotatable about the 1st caster axis line C1 with respect to the 1st fixed body 51. On the other hand, in the second caster 60 attached to the rear leg 16 , the second rotating body 62 cannot rotate about the second caster axis C2 with respect to the second fixed body 61 .

在如圖3所示般將握把40配置於對面推動位置即第二位置的情況下，操作者可自與嬰幼兒對面的前腿14側的位置握持握把40而操縱嬰兒車10，以嬰兒車10的後腿側為行進方向的前方的方式使嬰兒車10行進。此時，後腿16位於嬰兒車10的行進方向的前方，前腿14位於嬰兒車10的行進方向的後方。而且，在安裝於前腿14的第一腳輪50中，第一旋轉體52相對於第一固定體51以第一腳輪軸線C1為中心不可旋轉。另一方面，在安裝於後腿16的第二腳輪60中，第二旋轉體62相對於第二固定體61以第二腳輪軸線C2為中心可旋轉。 As shown in FIG. 3 , when the handle 40 is disposed at the opposite push position, that is, the second position, the operator can operate the stroller 10 by grasping the handle 40 from the position on the front leg 14 side opposite to the infant. The stroller 10 is made to travel so that the rear leg side of the stroller 10 is forward in the traveling direction. At this time, the rear legs 16 are positioned forward in the traveling direction of the stroller 10 , and the front legs 14 are positioned rearward in the traveling direction of the stroller 10 . Moreover, in the 1st caster 50 attached to the front leg 14, the 1st rotating body 52 cannot rotate about the 1st caster axis line C1 with respect to the 1st fixed body 51. On the other hand, in the second caster 60 attached to the rear leg 16 , the second rotating body 62 is rotatable about the second caster axis C2 with respect to the second fixed body 61 .

即，伴隨著在第一位置與第二位置之間切換握把40被保持的位置，而對以腳輪軸線C1、腳輪軸線C2為中心的支撐車輪56、車輪66的旋轉體52、旋轉體62的可否旋轉進行切換。具體 而言，位於嬰兒車10的移動方向上的前方的腳輪50、腳輪60作為腳輪而發揮功能，支撐車輪56、車輪66的旋轉體52、旋轉體62以腳輪軸線C1、腳輪軸線C2為中心而旋轉。另一方面，位於嬰兒車10的移動方向的後方的腳輪50、腳輪60不作為腳輪發揮功能，而限制支撐車輪56、車輪66的旋轉體52、旋轉體62以腳輪軸線C1、腳輪軸線C2為中心的旋轉。藉由根據此種握把40的擺動位置而切換腳輪機構，可使操作者(監護人)的嬰兒車10提高操縱性。 That is, as the position in which the grip 40 is held is switched between the first position and the second position, the rotating body 52 and the rotating body 62 supporting the wheel 56 and the wheel 66 centered on the caster axis C1 and the caster axis C2 to switch whether to rotate or not. specific Specifically, the casters 50 and 60 positioned forward in the moving direction of the stroller 10 function as casters, and the wheels 56 and the rotating body 52 supporting the wheels 66 and the rotating body 62 are centered on the caster axis C1 and the caster axis C2. rotate. On the other hand, the casters 50 and 60 located at the rear in the moving direction of the stroller 10 do not function as casters, and the swivel 52 and the swivel 62 that support the wheels 56 and 66 are restricted around the caster axis C1 and the caster axis C2 rotation. By switching the caster mechanism according to the swing position of the handle 40, the operator's (guardian's) stroller 10 can be improved in maneuverability.

此外，於握把40處於背面推動位置即第一位置的情況下，嬰幼兒可面向行進方向前方。因此，在嬰兒車10行進過程中，嬰幼兒可觀察風景並欣賞風景。於握把40處於對面推動位置即第二位置的情況下，監護人可一面確認嬰幼兒的狀態一面使嬰兒車10行進。因此，在將低月齡嬰幼兒載置於嬰兒車10時，大多將握把40配置於對面推動位置即第二位置，在將例如腰部已坐住的嬰幼兒載置於嬰兒車10時，傾向於將握把40配置於背面推動位置即第一位置。 In addition, when the handle 40 is in the back push position, that is, the first position, the infant can face forward in the traveling direction. Therefore, the infant can observe the scenery and enjoy the scenery while the stroller 10 is traveling. When the handle 40 is in the opposite push position, that is, the second position, the guardian can make the stroller 10 run while confirming the state of the infant. Therefore, when a low-month-old infant is placed on the stroller 10, the handle 40 is often arranged at the opposite push position, that is, the second position. The grip 40 tends to be placed in the rear push position, that is, the first position.

在將低月齡嬰幼兒載置於嬰兒車10時，對於嬰兒車10要求行進穩定性。根據圖示的嬰兒車10，在傾向於針對低月齡嬰幼兒而使用的對面推動狀態下的嬰兒車10、即握把40配置於對面推動位置即第二位置的狀態的嬰兒車10中，後腿16位於移動方向上的前方。而且，安裝於後腿16的第二腳輪60具有雙輪結構，包含一對後輪66。所述第二腳輪60具有接地面積大、強度高、且 於耐荷重上優異等特點。因此，在第二腳輪60位於移動方向前方而作為腳輪發揮功能的情況下，由於第二腳輪60為雙輪結構，而實現優異的行進穩定性。 When placing a low-month-old infant on the stroller 10, the stroller 10 is required to have running stability. According to the stroller 10 shown in the figure, in the stroller 10 in the opposite push state, which tends to be used for infants of young age, that is, the stroller 10 in the state in which the handle 40 is arranged in the second position, which is the opposite push position, The rear legs 16 are located forward in the moving direction. Furthermore, the second caster 60 attached to the rear leg 16 has a double-wheel structure and includes a pair of rear wheels 66 . The second caster 60 has a large grounding area, high strength, and It has the characteristics of excellent load resistance. Therefore, when the second caster 60 is positioned forward in the moving direction and functions as a caster, since the second caster 60 has a double-wheel structure, excellent running stability is realized.

又，雙輪結構的第二腳輪60具有在與行進方向正交的方向上分開的一對後輪66。因此，可有效地避免第二腳輪60整體、即一對後輪66兩者嵌入於在行進面上形成的槽等凹部。即，即便一個第二腳輪60的其中一個後輪66位於凹部上，藉由另一個後輪66維持於行進面上，亦可有效地防止第二腳輪60嵌入於凹部。藉此，有效地抑制產生非意圖的衝擊，在此方面上亦可使行進穩定性提高。 Moreover, the 2nd caster 60 of a two-wheel structure has a pair of rear-wheel 66 spaced apart in the direction orthogonal to a traveling direction. Therefore, it is possible to effectively prevent the entire second caster 60, that is, both the pair of rear wheels 66 from being fitted into recesses such as grooves formed on the running surface. That is, even if one of the rear wheels 66 of one second caster 60 is located on the recessed portion, the other rear wheel 66 is maintained on the running surface, so that the second caster 60 can be effectively prevented from being embedded in the recessed portion. Thereby, generation of an unintended shock is effectively suppressed, and also in this respect, the running stability can be improved.

即，於握把40配置於對面推動位置即第二位置的狀態的嬰兒車10中，第二腳輪60作為位於移動方向前方的腳輪而發揮功能，藉此適宜地獲得傾向於載置於所述嬰兒車10的低月齡嬰幼兒所要求的行進穩定性。 That is, in the stroller 10 in which the handle 40 is disposed in the opposite push position, that is, the second position, the second caster 60 functions as a caster located forward in the moving direction, whereby the tendency to be placed on the stroller 10 is suitably obtained. The traveling stability required by the baby carriage 10 of a young age.

另一方面，隨著不斷成長，而嬰幼兒的體重不斷增加。伴隨著體重的增加，而對嬰兒車10要求操縱性(轉向性、行進操作性)。又，如上文所述般，伴隨著嬰幼兒的成長，在握把40配置於背面推動位置即第一位置的狀態下使用嬰兒車10，以使嬰幼兒喜歡使用嬰兒車10外出。於本實施形態的嬰兒車10中，在握把40配置於背面推動位置即第一位置的狀態下，前腿14位於移動方向上的前方。而且，安裝於前腿14的第一腳輪50具有單輪構造，僅包含一個前輪56。於所述第一腳輪50中，由於行進面與 前輪56的摩擦阻力變小，故易於使第一旋轉體52相對於第一固定體51以第一腳輪軸線C1為中心而旋轉。因此，藉由施加至握把40的力可使前輪56與第一旋轉體52一起相對於第一固定體51容易地旋轉，故可發揮優異的操縱性。 On the other hand, infants and toddlers gain weight as they grow. As the weight increases, maneuverability (steerability, travel maneuverability) is required for the stroller 10 . In addition, as described above, the baby carriage 10 is used with the handle 40 arranged at the back push position, that is, the first position, in accordance with the growth of the baby, so that the baby may like to use the baby carriage 10 to go out. In the stroller 10 of the present embodiment, the front legs 14 are positioned forward in the moving direction in a state where the handle 40 is arranged at the back push position, that is, the first position. Furthermore, the first caster 50 attached to the front leg 14 has a single-wheel structure and includes only one front wheel 56 . In the first caster 50, due to the traveling surface and the Since the frictional resistance of the front wheel 56 is reduced, the first rotating body 52 can be easily rotated about the first caster axis C1 with respect to the first fixed body 51 . Therefore, the front wheel 56 can be easily rotated relative to the first fixed body 51 together with the first rotating body 52 by the force applied to the grip 40, so that excellent maneuverability can be exhibited.

如以上所述般，藉由握把40位於對面推動位置即第二位置，而第二腳輪60作為位於移動方向前方的腳輪而發揮功能，作為結果，對嬰兒車10賦予傾向於載置於所述嬰兒車10的低月齡嬰幼兒所要求的行進穩定性。另一方面，藉由握把40位於背面推動位置即第一位置，而第一腳輪50作為位於移動方向前方的腳輪而發揮功能，從而對嬰兒車10賦予傾向於載置於所述嬰兒車10的長大的嬰幼兒所要求的操縱性。即，可根據可擺動的握把40的配置而使嬰兒車10的特性變化，從而可對嬰兒車10賦予特別是根據握把40的位置而要求的特性。 As described above, since the handle 40 is located at the opposite push position, that is, the second position, and the second caster 60 functions as a caster located forward in the moving direction, as a result, the stroller 10 is provided with a tendency to be placed in any position. The traveling stability required by the low-month-old infant of the stroller 10 is described. On the other hand, since the handle 40 is located at the back push position, that is, the first position, and the first caster 50 functions as a caster located forward in the moving direction, the stroller 10 is provided with a tendency to be placed on the stroller 10 . of the manipulative demands of grown-up infants and young children. That is, the characteristics of the stroller 10 can be changed according to the arrangement of the swingable handle 40 , and the characteristics required in particular according to the position of the handle 40 can be imparted to the stroller 10 .

此外，圖示的嬰兒車10的本體框架12具有：第一連桿L1，可轉動地連接於前腿14及後腿16；第二連桿L2，可轉動地連接於第一連桿L1的後端部分；第三連桿L3，可轉動地連接於前腿14；以及第四連桿L4，可轉動地連接於後腿16的中間部分。第二連桿L2可轉動地連接於第三連桿L3及第四連桿L4的至少一者。又，第三連桿L3可轉動地連接於第四連桿L4及第二連桿L2的至少一者。進而，第四連桿L4可轉動地連接於第二連桿L2及第三連桿L3的至少一者。 In addition, the body frame 12 of the illustrated stroller 10 has: a first link L1 rotatably connected to the front leg 14 and the rear leg 16; and a second link L2 rotatably connected to the first link L1 The rear end portion; the third link L3 , which is rotatably connected to the front leg 14 ; and the fourth link L4 , which is rotatably connected to the middle portion of the rear leg 16 . The second link L2 is rotatably connected to at least one of the third link L3 and the fourth link L4. In addition, the third link L3 is rotatably connected to at least one of the fourth link L4 and the second link L2. Furthermore, the fourth link L4 is rotatably connected to at least one of the second link L2 and the third link L3.

於此種嬰兒車10中，載置於嬰兒車10的嬰幼兒的重心 在前後方向上較前腿14更接近於後腿16。特別是，於圖示的嬰兒車10中，在圖2及圖3所示的側視下，第三連桿L3與第四連桿L4及第二連桿L2的連接位置(軸構件30的位置)位於較後腿16更靠後方，特別是，於此種嬰兒車10中，嬰幼兒的重心於前後方向上與前腿14相比更易於接近後腿16。因此，於圖示的嬰兒車10中，嬰幼兒的體重主要藉由後腿16及固定於後腿16的下端的第二腳輪60而支撐。如上文所述般，第二腳輪60於寬度方向上分開且具有一對後輪66。因此，第二腳輪60具有接地面積大、強度高、且於耐荷重上優異等特點。藉此，根據圖示的嬰兒車10，可穩定地支撐嬰幼兒的體重。 In such a stroller 10, the center of gravity of the infant placed on the stroller 10 It is closer to the rear leg 16 than the front leg 14 in the front-rear direction. In particular, in the illustrated stroller 10, in the side view shown in FIGS. 2 and 3 , the connection positions of the third link L3, the fourth link L4, and the second link L2 (the position of the shaft member 30 position) is located more rearward than the rear legs 16 , and in particular, in such a stroller 10 , the center of gravity of the infant is easier to approach the rear legs 16 than the front legs 14 in the front-rear direction. Therefore, in the stroller 10 shown in the figure, the weight of the infant is mainly supported by the rear legs 16 and the second casters 60 fixed to the lower ends of the rear legs 16 . As described above, the second caster 60 is separated in the width direction and has a pair of rear wheels 66 . Therefore, the second caster 60 has the characteristics of large ground contact area, high strength, and excellent load resistance. Thereby, according to the stroller 10 shown in the figure, the weight of the infant can be stably supported.

再者，一般而言，載置於嬰兒車的嬰幼兒的重心位置亦取決於斜倚角度，但大致位於支撐嬰幼兒的臀部的座部支撐體的後方部分上。特別是，在嬰兒車上的嬰幼兒的重心位置傾向於位於座部支撐體、與支撐嬰幼兒的背部的背部支撐體的連接位置附近上。於圖示的嬰兒車10中，基座布材34與已調節基座布材34的框架材24構成經由座席芯材13支撐嬰幼兒的臀部的座部支撐體。又，基座布材34與已調節基座布材34的基座框架31構成經由座席芯材13支撐嬰幼兒的背部的背部支撐體。因此，如圖7A及圖7B所示，載置於圖示的嬰兒車10的嬰幼兒的重心CG不是取決於可擺動的握把40被保持的位置，而是位於在前後方向上的框架材24的後方部分上、更嚴格而言位於基座框架31與框架材24的可轉動的連接位置上、即軸構件30的周邊上。因此，載置於 所述嬰兒車10的嬰幼兒的重心CG在前後方向上較前腿14更接近於後腿16。因此，經由安裝於後腿16且包含一對後輪66的第二腳輪60，穩定地支撐嬰幼兒的體重。 In addition, in general, the position of the center of gravity of the infant placed on the stroller also depends on the reclining angle, but is generally located on the rear portion of the seat support body that supports the buttocks of the infant. In particular, the position of the center of gravity of the infant on the stroller tends to be in the vicinity of the connection position between the seat support and the back support that supports the infant's back. In the stroller 10 shown in the figure, the base cloth 34 and the frame material 24 to which the base cloth 34 has been adjusted constitute a seat support body that supports the buttocks of the infant through the seat core material 13 . Moreover, the base fabric 34 and the base frame 31 in which the base fabric 34 has been adjusted constitute a back support body that supports the back of the infant via the seat core 13 . Therefore, as shown in FIGS. 7A and 7B , the center of gravity CG of the infant placed on the illustrated stroller 10 does not depend on the position where the swingable grip 40 is held, but on the frame material in the front-rear direction. On the rear portion of 24 , more strictly, on the rotatable connection position of the base frame 31 and the frame material 24 , that is, on the periphery of the shaft member 30 . Therefore, placed in The center of gravity CG of the infant in the stroller 10 is closer to the rear leg 16 than the front leg 14 in the front-rear direction. Therefore, the weight of the infant is stably supported via the second casters 60 including the pair of rear wheels 66 attached to the rear legs 16 .

進而，如圖7A及圖7B所示，自嬰幼兒的重心CG至後輪66的接地位置的沿著前後方向的距離LY短於自嬰幼兒的重心CG至前輪56的接地位置的沿著前後方向的距離LX。產生下述傾向，即：此種嬰兒車10針對朝寬度方向的搖晃、翹曲、變形、傾倒(傾斜)等的穩定性取決於後輪66的寬度方向位置。 Furthermore, as shown in FIGS. 7A and 7B , the distance LY in the front-rear direction from the center of gravity CG of the infant to the ground contact position of the rear wheel 66 is shorter than the distance LY from the center of gravity CG of the infant to the ground contact position of the front wheel 56 along the front and rear directions The direction distance LX. There is a tendency that the stability of such a stroller 10 against shaking, warping, deformation, tipping (tilting) and the like in the width direction depends on the widthwise position of the rear wheel 66 .

另一方面，如圖6所示，各第二腳輪60的一對後輪66中位於寬度方向外側的後輪66較與所述第二腳輪60在寬度方向上位於同一側(左側或右側)的第一腳輪50的前輪56，在寬度方向上位於更靠外側。因此，以使嬰幼兒的重心CG在寬度方向上位於較後輪66更靠外側的方式而形成的嬰兒車10的傾斜角θ2(參照圖8A)大於以使嬰幼兒的重心CG在寬度方向上位於較前輪56更靠外側的方式而形成的嬰兒車10的傾斜角θ1(參照圖8B)。因此，於圖示的嬰兒車10中，藉由包含一對後輪66的第二腳輪60，針對朝側方向的搖晃、翹曲、變形、傾倒(傾斜)等發揮優異的穩定性。 On the other hand, as shown in FIG. 6 , among the pair of rear wheels 66 of each second caster 60 , the rear wheel 66 located on the outer side in the width direction is located on the same side (left or right) in the width direction as the second caster 60 in the width direction. The front wheel 56 of the first caster 50 is located further outside in the width direction. Therefore, the inclination angle θ2 (refer to FIG. 8A ) of the stroller 10 formed so that the center of gravity CG of the infant is located outside the rear wheel 66 in the width direction is larger than that so that the center of gravity CG of the infant is located in the width direction. The inclination angle θ1 of the stroller 10 formed so as to be positioned outside the front wheels 56 (see FIG. 8B ). Therefore, in the stroller 10 shown in the figure, the second caster 60 including the pair of rear wheels 66 exhibits excellent stability against lateral shaking, warping, deformation, tipping (tilting), and the like.

特別是在圖示的嬰兒車10中，前腿14及後腿16在寬度方向上位於相互重合的區域，進而，前腿14與第一腳輪50的前輪56亦在寬度方向上位於相互重合的區域。而且，在寬度方向上，各第一腳輪50的前輪56位於第二腳輪60的一對後輪66之間， 所述第二腳輪60與所述第一腳輪50在寬度方向上位於同一側。因此，在針對朝寬度方向的變形或傾斜確保優異的穩定性的同時，可抑制嬰兒車10的大型化且賦予優美的外觀。 In particular, in the stroller 10 shown in the figure, the front legs 14 and the rear legs 16 are located in overlapping regions in the width direction, and further, the front legs 14 and the front wheels 56 of the first casters 50 are also located in the overlapping regions in the width direction. area. Moreover, in the width direction, the front wheel 56 of each first caster 50 is located between the pair of rear wheels 66 of the second caster 60, The second caster 60 and the first caster 50 are located on the same side in the width direction. Therefore, while ensuring excellent stability against deformation or inclination in the width direction, the stroller 10 can be restrained from being increased in size, and a beautiful appearance can be imparted.

特別是於圖示的嬰兒車10中，如圖6所示，於嬰兒車10直行狀態下的寬度方向上，各第一腳輪50的前輪56位於第二腳輪60的一對後輪66的中心，所述第二腳輪60與所述第一腳輪50在寬度方向上位於同一側。因此，可進一步使行進穩定性提高，從而可發揮優異的直行性。 In particular, in the stroller 10 shown in the figure, as shown in FIG. 6 , the front wheels 56 of the first casters 50 are located at the centers of the pair of rear wheels 66 of the second casters 60 in the width direction when the stroller 10 is traveling straight. , the second caster 60 and the first caster 50 are located on the same side in the width direction. Therefore, the running stability can be further improved, and excellent straightness can be exhibited.

此外，於圖示的嬰兒車10中，在寬度方向上，各第一腳輪50的第一腳輪軸線C1與第二腳輪60的第二腳輪軸線C2位於同一位置，所述第二腳輪60與第一腳輪50在寬度方向上位於同一側。因此，改善行進穩定性，且亦可提高轉向性、行進操作性。 In addition, in the stroller 10 shown in the figure, the first caster axis C1 of each first caster 50 and the second caster axis C2 of the second caster 60 are located at the same position in the width direction. A caster 50 is located on the same side in the width direction. Therefore, the running stability can be improved, and the steering performance and the running operability can also be improved.

再者，如圖2所示，第一腳輪50的前輪56的直徑D1小於第二腳輪60的後輪66的直徑D2。根據此種第一腳輪50，可更加易於產生以第一腳輪軸線C1為中心的第一旋轉體52相對於第一固定體51的旋轉。藉此，可進一步提高握把40位於背面推動位置即第一位置的情況下的嬰兒車10的操縱性。 Furthermore, as shown in FIG. 2 , the diameter D1 of the front wheel 56 of the first caster 50 is smaller than the diameter D2 of the rear wheel 66 of the second caster 60 . According to such a first caster 50 , the rotation of the first rotating body 52 with respect to the first fixed body 51 about the first caster axis C1 can be more easily generated. Thereby, when the handle|steering-wheel 40 is located in the back push position, ie, the 1st position, the maneuverability of the stroller 10 can be improved further.

此外，圖示的嬰兒車10僅在握把40配置於第一位置的狀態下能夠自展開狀態開始折疊動作。而且，與握把40處於第一位置的嬰兒車10同樣地，在折疊的嬰兒車10中容許第一腳輪50的第一旋轉體52及前輪56相對於第一固定體51的旋轉，且限制第二腳輪60的第二旋轉體62及後輪66相對於第二固定體61的 旋轉。即，在折疊狀態下可相對於第一固定體51以第一腳輪軸線C1為中心而旋轉的前輪56的直徑比較小。根據此種嬰兒車10，如圖4所示般，可有效地使處於折疊的狀態的嬰兒車10的立起姿勢穩定。 In addition, the illustrated stroller 10 can start the folding operation from the unfolded state only when the handle 40 is arranged in the first position. Also, in the folded stroller 10, the first rotating body 52 of the first caster 50 and the front wheel 56 are allowed to rotate relative to the first fixed body 51 in the same manner as the stroller 10 in which the handle 40 is in the first position, and the rotation of the first fixed body 51 is restricted. The second rotating body 62 of the second caster 60 and the rear wheel 66 are relative to the second fixed body 61 rotate. That is, the diameter of the front wheel 56 that is rotatable about the first caster axis C1 with respect to the first fixed body 51 in the folded state is relatively small. According to such a stroller 10 , as shown in FIG. 4 , the standing posture of the stroller 10 in the folded state can be effectively stabilized.

又，如圖6所示，於處於直行狀態的嬰兒車10中，即於與前後方向平行的方向上前進的嬰兒車10中，各第一腳輪50的前輪56位於第二腳輪60的一對後輪66之間，所述第二腳輪60與所述第一腳輪50在寬度方向上位於同一側。特別是，前輪56的寬度方向外側端與位於寬度方向外側的後輪66的寬度方向內側端相比位於更靠寬度方向內側，且前輪56的寬度方向內側端與位於寬度方向內側的後輪66的寬度方向外側端相比位於更靠寬度方向外側。換言之，於處於直行狀態的嬰兒車10中，寬度方向上的一對後輪66的間隔S2大於寬度方向上的前輪56的寬度W1。根據此種嬰兒車10，可有效地抑制嬰兒車10朝寬度方向的傾倒，且可有效地使嬰兒車10的直行狀態穩定。 In addition, as shown in FIG. 6 , in the stroller 10 in the straight-running state, that is, in the stroller 10 traveling in a direction parallel to the front-rear direction, the front wheels 56 of the first casters 50 are located in a pair of the second casters 60 . Between the rear wheels 66, the second caster 60 and the first caster 50 are located on the same side in the width direction. In particular, the outer end in the width direction of the front wheel 56 is located further inward in the width direction than the inner end in the width direction of the rear wheel 66 located on the outer side in the width direction, and the inner end in the width direction of the front wheel 56 is located closer to the inner end in the width direction than the inner end in the width direction of the rear wheel 66 located on the inner side in the width direction. The outer end in the width direction is located further outside in the width direction. In other words, in the stroller 10 in the straight running state, the interval S2 of the pair of rear wheels 66 in the width direction is larger than the width W1 of the front wheels 56 in the width direction. According to such a stroller 10 , the fall of the stroller 10 in the width direction can be effectively suppressed, and the straight running state of the stroller 10 can be effectively stabilized.

進而，於圖6所示的示例中，於處於直行狀態的嬰兒車10的寬度方向上，一對後輪66的間隔S2大於第一固定體51的寬度W51。又，於處於直行狀態的嬰兒車10中，寬度方向上的一對後輪66的間隔S2大於寬度方向上的第一旋轉體52的第一旋轉體基座53的寬度W53，且大於寬度方向上的第一旋轉體52的第一旋轉體保持器54的寬度W54。根據此種示例，不僅可使握把40處於背面推動位置即第一位置(圖2所示的握把40的位置)的情 況下的操縱性優異，而且可使握把40處於對面推動位置即第二位置(圖3所示的握把40的位置)的情況下的行進穩定性更加優異。 Furthermore, in the example shown in FIG. 6 , in the width direction of the stroller 10 in the straight-running state, the distance S2 between the pair of rear wheels 66 is larger than the width W51 of the first fixed body 51 . In addition, in the stroller 10 in the straight-running state, the interval S2 of the pair of rear wheels 66 in the width direction is larger than the width W53 of the first rotating body base 53 of the first rotating body 52 in the width direction, and larger than the width direction. The width W54 of the first rotating body holder 54 on the first rotating body 52 . According to such an example, not only can the grip 40 be in the back push position, that is, the first position (the position of the grip 40 shown in FIG. 2 ) In this case, the steerability is excellent, and the running stability when the grip 40 is in the second position (the position of the grip 40 shown in FIG. 3 ), which is the opposite push position, can be further improved.

於以上所說明的一實施形態中，嬰兒車10具有：本體框架12，具有前腿14及後腿16；握把40，於第一位置與第二位置之間可擺動地連接於本體框架12；第一腳輪50，安裝於前腿14；以及第二腳輪60，安裝於後腿16。第一腳輪50具有：第一固定體51，固定於前腿14；第一旋轉體52，以第一腳輪軸線C1為中心可旋轉地支撐於第一固定體51；以及單個前輪56，可旋轉地支撐於第一旋轉體52。第二腳輪60具有：第二固定體61，固定於後腿16；第二旋轉體62，以第二腳輪軸線C2為中心可旋轉地支撐於第二固定體61；以及一對後輪66，可旋轉地支撐於第二旋轉體62。而且，於握把40處於第二位置的情況下限制第一旋轉體52相對於第一固定體51的旋轉，於握把40處於第一位置的情況下限制第二旋轉體62相對於第二固定體61的旋轉。 In one embodiment described above, the stroller 10 includes: a main body frame 12 having front legs 14 and rear legs 16; a handle 40 swingably connected to the main body frame 12 between the first position and the second position ; The first caster 50, mounted on the front leg 14; and the second caster 60, mounted on the rear leg 16. The first caster 50 has: a first fixed body 51 fixed to the front leg 14; a first rotating body 52 rotatably supported on the first fixed body 51 around the first caster axis C1; and a single front wheel 56, rotatable is supported on the first rotating body 52 . The second caster 60 has: a second fixed body 61 fixed to the rear leg 16; a second rotating body 62 rotatably supported on the second fixed body 61 around the second caster axis C2; and a pair of rear wheels 66, It is rotatably supported on the second rotating body 62 . When the grip 40 is at the second position, the rotation of the first rotating body 52 relative to the first fixed body 51 is restricted, and when the grip 40 is at the first position, the rotation of the second rotating body 62 relative to the second rotating body 62 is restricted. Rotation of the fixed body 61 .

根據此種一實施形態，藉由握把40位於第二位置，第二腳輪60作為位於移動方向前方的腳輪而發揮功能，從而可提高嬰兒車10的行進穩定性。另一方面，藉由握把40位於第一位置，第一腳輪50作為位於移動方向前方的腳輪而發揮功能，從而可改善嬰兒車10的操縱性。即，可根據可擺動的握把40的配置而使嬰兒車10的特性變化。 According to such an embodiment, when the handle 40 is located at the second position, the second caster 60 functions as a caster located forward in the moving direction, thereby improving the traveling stability of the stroller 10 . On the other hand, when the handle 40 is located at the first position, the first caster 50 functions as a caster located forward in the moving direction, thereby improving the maneuverability of the stroller 10 . That is, the characteristics of the stroller 10 can be changed according to the arrangement of the swingable handle 40 .

再者，於圖6所示的示例中，於直行狀態下的嬰兒車10的寬度方向上，後輪66的寬度W2窄於前輪56的寬度W1。根據 此種示例，可維持將握把40配置於第二位置的狀態下的行進穩定性且維持將握把40配置於第一位置的狀態下的操縱性，並且改善將握把40配置於第二位置的狀態下的操縱性且改善將握把40配置於第一位置的狀態下的行進穩定性。 Furthermore, in the example shown in FIG. 6 , the width W2 of the rear wheel 66 is narrower than the width W1 of the front wheel 56 in the width direction of the stroller 10 in the straight running state. according to Such an example can maintain the running stability in the state where the grip 40 is arranged at the second position, maintain the maneuverability in the state where the grip 40 is arranged at the first position, and improve the grip 40 arranged at the second position. The maneuverability in the state of the position is improved, and the running stability of the state in which the grip 40 is arranged in the first position is improved.

進而，於圖示的嬰兒車10中，在寬度方向上，第一腳輪50的前輪56與第一固定體51的位置重合。而且，第一腳輪50的前輪56在寬度方向上與第一腳輪軸線C1重合。於此種嬰兒車10中，如圖2所示般，已確認：藉由加高第一腳輪50的第一旋轉體52的第一相向面SS1的高度H1，而在將握把40配置於第一位置的狀態下，更易於使第一旋轉體52相對於第一固定體51以腳輪軸線C1為中心而旋轉。即，藉由加高第一相向面SS1的高度H1，可進一步改善將握把40配置於第一位置的狀態下的操縱性。 Furthermore, in the stroller 10 shown in the figure, the position of the front wheel 56 of the first caster 50 and the first fixed body 51 overlap with each other in the width direction. Furthermore, the front wheel 56 of the first caster 50 overlaps the first caster axis C1 in the width direction. In the stroller 10 of this type, as shown in FIG. 2 , it has been confirmed that by increasing the height H1 of the first opposing surface SS1 of the first rotating body 52 of the first caster 50 , the handle 40 is disposed on the In the state of the first position, it is easier to rotate the first rotating body 52 about the caster axis C1 with respect to the first fixed body 51 . That is, by increasing the height H1 of the first opposing surface SS1, the operability in the state where the grip 40 is arranged at the first position can be further improved.

另一方面，於圖示的嬰兒車10中，第二腳輪60的後輪66位於自第二固定體61在寬度方向上偏移的位置。因此，第二腳輪60的後輪66自第二腳輪軸線C2在寬度方向上偏移。於此種嬰兒車10中，如圖2所示般，已確認：藉由降低第二腳輪60的第二旋轉體62的第二相向面SS2的高度H2，而在將握把40配置於第二位置的狀態下，可有效地限制第二固定體61相對於第二旋轉體62以腳輪軸線C1為中心非意圖地旋轉。即，藉由降低第二相向面SS2的高度H2，可進一步改善將握把40配置於第二位置的狀態下的行進穩定性。 On the other hand, in the stroller 10 shown in the figure, the rear wheel 66 of the second caster 60 is located at a position shifted in the width direction from the second fixed body 61 . Therefore, the rear wheel 66 of the second caster 60 is offset in the width direction from the second caster axis C2. In the stroller 10 of this type, as shown in FIG. 2 , it has been confirmed that by lowering the height H2 of the second facing surface SS2 of the second rotating body 62 of the second caster 60 , the handle 40 is disposed on the first In the two-position state, unintended rotation of the second fixed body 61 relative to the second rotating body 62 around the caster axis C1 can be effectively restricted. That is, by reducing the height H2 of the second opposing surface SS2, the running stability in the state where the grip 40 is arranged at the second position can be further improved.

而且，於圖示的示例中，第一相向面SS1的高度H1高於 第二相向面SS2的高度H2。第一相向面SS1的高度H1為前輪56的直徑D1以上。第一相向面SS1的高度H1為後輪66的直徑D2以上。根據此種構成，可使將握把40配置於第一位置的狀態下的操縱性更加優異。 Moreover, in the illustrated example, the height H1 of the first facing surface SS1 is higher than The height H2 of the second facing surface SS2. The height H1 of the first facing surface SS1 is equal to or greater than the diameter D1 of the front wheel 56 . The height H1 of the first facing surface SS1 is equal to or greater than the diameter D2 of the rear wheel 66 . According to such a configuration, the operability in the state where the grip 40 is arranged at the first position can be further improved.

同樣地，於圖示的示例中，第一相向面SS1的高度H1高於第二相向面SS2的高度H2。第二相向面SS2的高度H2小於前輪56的直徑D1。第二相向面SS2的高度H2小於後輪66的直徑D2。根據此種構成，可使將握把40配置於第二位置的狀態下的行進穩定性更加優異。 Likewise, in the illustrated example, the height H1 of the first facing surface SS1 is higher than the height H2 of the second facing surface SS2. The height H2 of the second facing surface SS2 is smaller than the diameter D1 of the front wheel 56 . The height H2 of the second facing surface SS2 is smaller than the diameter D2 of the rear wheel 66 . According to such a configuration, the running stability in the state where the grip 40 is arranged at the second position can be further improved.

參照圖示的具體例對一實施形態進行了說明，但圖示的具體例並非意圖限定一實施形態。上文所述的一實施形態能夠以其他各種具體例而實施，在不脫離其主旨的範圍內可進行各種省略、置換、變更、追加等。例如，於上文所述的具體例中，僅在握把40配置於第一位置的情況下，嬰兒車10可自展開狀態朝折疊狀態開始折疊動作，但並不限定於此。例如，可為僅在握把40配置於第二位置的情況下，嬰兒車10可開始折疊動作，或者是，亦可為無論握把40配置於第一位置還是第二位置的任一者，嬰兒車10均可開始折疊動作。 An embodiment has been described with reference to specific examples shown in the drawings, but the specific examples shown in the drawings are not intended to limit an embodiment. The above-described one embodiment can be implemented in other various specific examples, and various omissions, substitutions, changes, additions, and the like can be made without departing from the gist. For example, in the specific example described above, only when the handle 40 is arranged at the first position, the stroller 10 can start to fold from the unfolded state to the folded state, but it is not limited to this. For example, the stroller 10 may start to fold only when the handle 40 is arranged at the second position, or the baby may start the folding operation regardless of whether the handle 40 is arranged at the first position or the second position. The cart 10 can start the folding action.
