Each second link 22 is connected to the side portion 41a of the seat support body 40 on the same side in the width direction, and is connected to the first link 21 (front-rear connection portion 53 ) on the same side in the width direction.

在圖示的示例中,第2連桿22由支承框架件55構成。支承框架件55構成為金屬製的棒狀的部件。如圖1所示,支承框架件55在上端部及下端部中在寬度方向延伸。支承框架件55在上端部及下端部之間在上下方向延伸。各支承框架件55在其上端部中朝向寬度方向的外側彎曲且貫通位於寬度方向上的同一側的座安裝部件44。第4轉動軸線RA4與具有棒狀形狀的支承框架件55的上端部的中心軸線一致。各支承框架件55在其下端部中朝向寬度方向的內側彎曲且貫通位於寬度方向上的同一側的前後連結部53。第5轉動軸線RA5與具有棒狀形狀的支承框架件55的下端部的中心軸線一致。根據這樣的支承框架件55的安裝構成,在對座支承體40施加向寬度方向的力時,能夠有效地防止支承框架件 55從第1連桿21或座支承體40脫離,結果為,能夠由支承框架件55穩定地支承座支承體40。 In the example shown in the figure, the second link 22 is constituted by a support frame member 55 . The support frame 55 is configured as a metal rod-shaped member. As shown in FIG. 1 , the support frame 55 extends in the width direction at the upper end and the lower end. The support frame 55 extends in the up-down direction between the upper end portion and the lower end portion. Each support frame member 55 is bent toward the outer side in the width direction in the upper end portion thereof, and penetrates the seat mounting member 44 located on the same side in the width direction. The fourth rotation axis RA4 coincides with the center axis of the upper end portion of the rod-shaped support frame 55 . Each support frame member 55 is bent toward the inner side in the width direction in the lower end portion thereof, and penetrates the front and rear connecting portions 53 located on the same side in the width direction. The fifth rotation axis RA5 coincides with the center axis of the lower end portion of the rod-shaped support frame 55 . According to such an attachment structure of the support frame 55, when a force in the width direction is applied to the seat support body 40, the support frame can be effectively prevented from being supported. 55 is detached from the first link 21 or the seat support body 40 , and as a result, the seat support body 40 can be stably supported by the support frame 55 .

另外,寬度方向上的內側(內部)是指靠近寬度方向上的嬰兒車10的中心的一側。寬度方向上的外側(外部)是指從寬度方向上的嬰兒車10的中心遠離的一側。 In addition, the inner side (inside) in the width direction refers to the side close to the center of the stroller 10 in the width direction. The outer side (outside) in the width direction refers to the side away from the center of the stroller 10 in the width direction.

支承框架件55在圖4所示的側視狀態下沿大致豎直方向延伸。典型地,支承框架件55在側視狀態下相對於上下方向所成的角度較佳為10°以下,更佳為5°以下,進一步較佳為0°。根據這樣的支承框架件55,能夠從下方穩定地支承在後端部分與握把30連接的座支承體40的前方部分。 The support frame member 55 extends in a substantially vertical direction in the side view state shown in FIG. 4 . Typically, the angle formed by the support frame member 55 with respect to the vertical direction in a side view is preferably 10° or less, more preferably 5° or less, and further preferably 0°. According to such a support frame 55, the front portion of the seat support body 40 whose rear end portion is connected to the handle 30 can be stably supported from below.

此外,如圖1所示,各支承框架件55以從上向下朝向寬度方向的內側的方式相對於上下方向傾斜。結果為,一對支承框架件55在寬度方向上的隔開間隔在上下方向中從上朝下逐漸變窄。根據這樣的支承框架件55,即使在對座支承體40施加向寬度方向的力時,也能夠穩定地支承座支承體40。 Moreover, as shown in FIG. 1, each support frame 55 is inclined with respect to the up-down direction so that it may go inward in the width direction from the top down. As a result, the spaced interval in the width direction of the pair of support frame pieces 55 is gradually narrowed from top to bottom in the up-down direction. According to such a support frame 55, even when a force in the width direction is applied to the seat support body 40, the seat support body 40 can be stably supported.

In addition, the third link 23 is rotatably connected to the rear leg 62 . In the example shown in the figure, the third link 23 is rotatable with respect to the grip 30 and the seat support 40 about the first rotation axis RA1. The third link 23 is rotatably connected to the rear leg 62 about the sixth rotation axis RA6 extending in the width direction. The pair of third links 23 are provided to be spaced apart in the width direction, and the pair of rear legs 62 are also provided to be spaced apart in the width direction. Each third link 23 is rotatably connected to the shaft portion 31 a of the grip 30 on the same side in the width direction, and is rotatably connected to the rear leg 62 on the same side in the width direction.

各側方件16安裝於座支承體40與握把30。在圖示的示例中,各側方件16透過固定機構16a固定在位於寬度方向上的同一側的座框架41的側部41a與位於寬度方向上的同一側的握把主體31的軸部31a。握把30的可彎曲的位置(彎曲軸線BA的位置)位於座支承體40連接於握把30的位置與側方件16連接於握把30的位置之間。在特別圖示出的示例中,側方件16能夠以張緊的狀態維持在座框架41的側部41a與握把主體31的軸部31a之間。這樣的側方件16作為連結加強機構17連結而發揮功能,連結加強機構17位在座支承體40的與握把30連接的位置(第1轉動軸線RA1的位置)的前方的位置和握把30的與座支承體40連接的位置(第1轉動軸線RA1的位置)的上方的位置之間,將在後端部分與握把30連接的座支承體40的前方部分向上方吊起。透過作為連結加強機構17發揮功能的側方件16,能夠穩定地支承座支承體40。 Each side piece 16 is attached to the seat support body 40 and the handle 30 . In the illustrated example, each side member 16 is fixed to the side portion 41a of the seat frame 41 located on the same side in the width direction and the shaft portion 31a of the grip body 31 located on the same side in the width direction through the fixing mechanism 16a . The bendable position of the handle 30 (the position of the bending axis BA) is located between the position where the seat support 40 is connected to the handle 30 and the position where the side piece 16 is connected to the handle 30 . In the example shown in particular, the side piece 16 can be maintained between the side portion 41 a of the seat frame 41 and the shaft portion 31 a of the grip body 31 in a tensioned state. Such a side member 16 functions as a connection reinforcement mechanism 17 which is located in front of the position of the seat support body 40 connected to the handle 30 (the position of the first rotation axis RA1 ) and the handle 30 The front part of the seat support 40 connected to the handle 30 at the rear end is hoisted upward between the positions above the position connected to the seat support 40 (the position of the first rotation axis RA1). The seat support body 40 can be stably supported by the side member 16 functioning as the connection reinforcement mechanism 17 .

進而,圖3所示的側方件16在向座支承體40固定的位置與向握把30固定的位置之間的位置包括強化部件16b。強化部件16b局部地強化側方件16的剛性。即,設置有強化部件16b的位置的側方件16的剛性比未設置強化部件16b的位置的側方件16的剛性高。因此,透過設置側方件16,能夠將座支承體40的前方部分更穩定地向上方吊起。特別圖示出的強化部件16b由線材或帶材構成,沿著將側方件16向座支承體40固定的位置與側方件16向握把30固定的位置連結的直線而配置於該直線上。因此,能夠有效地加強側方件16從而穩定地支承座支承體40。 Furthermore, the side member 16 shown in FIG. 3 contains the reinforcement member 16b in the position between the position fixed to the seat support body 40, and the position fixed to the grip 30. The reinforcement member 16b reinforces the rigidity of the side member 16 locally. That is, the rigidity of the side member 16 at the position where the reinforcement member 16b is provided is higher than the rigidity of the side member 16 at the position where the reinforcement member 16b is not provided. Therefore, by providing the side member 16, the front part of the seat support body 40 can be hoisted upward more stably. The reinforcing member 16b shown in the drawing is composed of a wire or a tape, and is arranged along the straight line connecting the position where the side member 16 is fixed to the seat support body 40 and the position where the side member 16 is fixed to the grip 30. superior. Therefore, the side member 16 can be effectively reinforced and the seat support body 40 can be stably supported.

具有以上的構成的嬰兒車10能夠透過使嬰兒車主體20的各構成部件相對轉動而折疊。具體而言,透過如下面說明的那樣握持握把30從而操作嬰兒車10,能夠折疊嬰兒車10。透過折疊嬰兒車10,能夠將嬰兒車10的尺寸縮小到適於保管或搬運等的大小。 The stroller 10 having the above-described configuration can be folded by relatively rotating the respective components of the stroller body 20 . Specifically, the stroller 10 can be folded by operating the stroller 10 by gripping the handle 30 as described below. By folding the stroller 10, the size of the stroller 10 can be reduced to a size suitable for storage, transportation, or the like.

首先,將握把30暫且向後上方提起。然後,透過將握把30向下方下降,使由托架部件67構成的第4連桿24相對於後腿62在圖4中沿順時針方向轉動。隨著該操作,第1連桿21及第3連桿23相對於握把30在圖4中沿順時針方向轉動。其結果為,在側視狀態下握把30與前腿60在側視狀態下維持大致平行的配置同時相互接近,並且握把30的位置下降。 First, the grip 30 is temporarily lifted back upward. Then, by lowering the handle 30 downward, the fourth link 24 constituted by the bracket member 67 is rotated in the clockwise direction in FIG. 4 with respect to the rear leg 62 . In accordance with this operation, the first link 21 and the third link 23 are rotated in the clockwise direction in FIG. 4 with respect to the grip 30 . As a result, the grip 30 and the front legs 60 approach each other while maintaining a substantially parallel arrangement in the side view, and the position of the grip 30 is lowered.

此外,可轉動地連接於握把30的座支承體40透過由支承框架件55構成的第2連桿22與第1連桿21連結。因此,在嬰兒車10的折疊動作時的第1連桿21的動作經由第2連桿22傳遞到座支承體40。具體而言,如圖5所示,座支承體40在側視狀態下相對於握把30沿順時針方向轉動,接近握把30。 Moreover, the seat support body 40 which is rotatably connected to the grip 30 is connected to the first link 21 via the second link 22 constituted by the support frame 55 . Therefore, the movement of the first link 21 during the folding operation of the stroller 10 is transmitted to the seat support body 40 via the second link 22 . Specifically, as shown in FIG. 5 , the seat support body 40 is rotated clockwise with respect to the handle 30 in a side view state, and approaches the handle 30 .

此外,隨著前腿60及後腿62相互接近,站立部件70以從第1站立元件71及第2站立元件72的連接位置(第9轉動軸線RA9的位置)向下方突出的方式彎曲。 Moreover, as the front leg 60 and the rear leg 62 approach each other, the standing member 70 is bent so as to protrude downward from the connection position (position of the ninth rotation axis RA9 ) of the first standing element 71 and the second standing element 72 .

以上操作的結果為,能夠將嬰兒車10向圖5所示的第1折疊狀態折疊,從而能夠使前後方向及上下方向上的尺寸縮小。如圖5所示,能夠使處於第1折疊狀態的嬰兒車10在使站立部件70與一對後輪63接地的狀態下立起。另外,為了使嬰兒車10從圖5所示的第1折疊狀態向展開狀態展開,只要執行與上述折疊操作相反的步驟即可。 As a result of the above operation, the stroller 10 can be folded in the first folded state shown in FIG. 5 , and the dimensions in the front-rear direction and the vertical direction can be reduced. As shown in FIG. 5 , the stroller 10 in the first folded state can be made to stand up in a state where the stand member 70 is grounded to the pair of rear wheels 63 . In addition, in order to unfold|deploy the baby carriage 10 from the 1st folded state shown in FIG. 5 to the unfolded state, what is necessary is just to carry out the reverse procedure of the above-mentioned folding operation.

接著,透過使第2握把元件33相對於握把主體31的第1握把元件32以彎曲軸線BA為中心轉動,使握把30彎曲。由此,使嬰兒車10為圖6所示的第2折疊狀態,能夠大幅度地縮小在上下方向的尺寸。如圖6所示,能夠使處於第2折疊狀態的嬰兒車10在使站立部件70與一對後輪63接地的狀態下立起。另外,為了使嬰兒車10從圖6所示的第2折疊狀態向圖5所示的第1折疊狀態展開,只要執行與上述折疊操作相反的步驟即可。 Next, the grip 30 is bent by rotating the second grip element 33 with respect to the first grip element 32 of the grip main body 31 about the bending axis BA. Thereby, the stroller 10 is brought into the second folded state shown in FIG. 6 , and the size in the vertical direction can be greatly reduced. As shown in FIG. 6 , the stroller 10 in the second folded state can be made to stand up in a state where the stand member 70 is grounded to the pair of rear wheels 63 . In addition, in order to unfold|deploy the stroller 10 from the 2nd folded state shown in FIG. 6 to the 1st folded state shown in FIG. 5, what is necessary is just to carry out the reverse procedure of the above-mentioned folding operation.

在以上說明的嬰兒車10中,在用於折疊嬰兒車主體20的握把30、前腿60及後腿62的連桿構成的上方配置有座支承體40。特別地,座支承體40位於第1連桿21的上方,進一步位於第3連桿23的上方。因此,能夠將座支承體40保持在較高的位置。透過提高座支承體40的保持位置,能夠將就坐在該座支承體40上的嬰幼兒從嬰兒車10的行走面隔開。由此,能夠保護乘坐於嬰兒車10的嬰幼兒使其遠離來自行走面的輻射熱或行走面上的粉塵等,能夠提高乘坐舒適度。 In the stroller 10 described above, the seat support body 40 is disposed above the handle 30 for folding the stroller body 20 , the front legs 60 and the rear legs 62 constituted by links. In particular, the seat support body 40 is positioned above the first link 21 and further positioned above the third link 23 . Therefore, the seat support body 40 can be held in a high position. By raising the holding position of the seat support body 40 , the infant sitting on the seat support body 40 can be separated from the walking surface of the stroller 10 . Thereby, the infant riding on the stroller 10 can be protected from radiant heat from the walking surface, dust on the walking surface, and the like, and the riding comfort can be improved.

而為了限制不希望進行的折疊動作,嬰兒車主體20具有第1折疊限制部件26及第2折疊限制部件27。第1折疊限制部件26被握把30支承,限制握把30與其他構成元件的相對動作。第1折疊限制部件26透過限制握把30與其他任一構成元件的相對動作,例如限制第1~第4連桿21~24、前腿60及後腿62的任一個與握把30的相對動作,從而能夠限制嬰兒車10的折疊動作。第2折疊限制部件27被握把30支承,限制握把30的彎曲。 On the other hand, the stroller body 20 includes a first folding restricting member 26 and a second folding restricting member 27 in order to restrict an undesired folding operation. The first folding restricting member 26 is supported by the handle 30 and restricts the relative movement of the handle 30 and other components. The first folding restricting member 26 restricts the relative movement of the handle 30 and any other component, for example, restricts the relative movement between the first to fourth links 21 to 24 , the front leg 60 and the rear leg 62 and the handle 30 . operation, so that the folding operation of the stroller 10 can be restricted. The second folding restricting member 27 is supported by the grip 30 and restricts the bending of the grip 30 .

在圖示的嬰兒車10中,被握把30支承的第1折疊限制部件26透過未圖示的彈壓機構而被朝向下方彈壓。如圖7A~圖7C所示,被向下方彈壓的第 1折疊限制部件26從握把30向下方突出,進入設置在後腿62的凹部62c內。透過被握把30支承的第1折疊限制部件26與後腿62的凹部62c的卡合,握把30與後腿62的相對動作受到限制。另外,在圖示的示例中,如圖7A~圖7B所示,第1折疊限制部件26從握把30向寬度方向內側突出。被向下方彈壓的第1折疊限制部件26進入由托架部件67構成的第4連桿24的切口24a。透過被握把30支承的第1折疊限制部件26與第4連桿24的切口24a的卡合,握把30與第4連桿24的相對動作受到限制。根據這樣的第1折疊限制部件26,能夠限制隨著握把30相對於座支承體40的相對轉動而進行的嬰兒車10的折疊動作。由第1折疊限制部件26進行的對折疊動作的限制透過提起第1折疊限制部件26而被解除。 In the stroller 10 shown in the figure, the first folding restricting member 26 supported by the handle 30 is biased downward by a biasing mechanism not shown. As shown in FIGS. 7A to 7C , the The folding restricting member 26 protrudes downward from the handle 30 and enters into the recess 62c provided in the rear leg 62. The relative movement of the handle 30 and the rear leg 62 is restricted by the engagement of the first folding restricting member 26 supported by the handle 30 with the recessed portion 62 c of the rear leg 62 . In addition, in the illustrated example, as shown in FIGS. 7A to 7B , the first folding restricting member 26 protrudes inward in the width direction from the grip 30 . The first folding restricting member 26 that is pressed downward enters the cutout 24 a of the fourth link 24 formed by the bracket member 67 . The relative movement of the grip 30 and the fourth link 24 is restricted by the engagement of the first folding restricting member 26 supported by the grip 30 with the cutout 24 a of the fourth link 24 . According to such a first folding restricting member 26 , it is possible to restrict the folding operation of the stroller 10 accompanying the relative rotation of the handle 30 with respect to the seat support body 40 . The restriction of the folding movement by the first folding restricting member 26 is released by lifting the first folding restricting member 26 .

如圖7A~圖7C所示,第2折疊限制部件27配置在握把主體31的第1握把元件32及第2握把元件33連接的部位。第1握把元件32具有第1轉動殼體32a,第2握把元件33具有第2轉動殼體33a。第1轉動殼體32a及第2轉動殼體33a以彎曲軸線BA為中心可轉動地相互連接。第2折疊限制部件27設置在由第1轉動殼體32a及第2轉動殼體33a形成的殼體內。第1轉動殼體32a和第2轉動殼體33a在寬度方向上並列。第2折疊限制部件27以能夠在寬度方向上移動的方式被第2轉動殼體33a保持。第2折疊限制部件27透過彈壓機構35沿著寬度方向被朝向第1轉動殼體32a彈壓。第2折疊限制部件27位於橫跨第1轉動殼體32a及第2轉動殼體33a雙方的位置,由此使第1轉動殼體32a及第2轉動殼體33a的以彎曲軸線BA為中心的相對轉動受到限制。因此,透過將第2折疊限制部件27壓入第2轉動殼體33a內,能夠解除對握把30的彎曲限制。 As shown in FIGS. 7A to 7C , the second folding restricting member 27 is arranged at the portion where the first grip element 32 and the second grip element 33 of the grip body 31 are connected. The first grip element 32 has a first rotation case 32a, and the second grip element 33 has a second rotation case 33a. The first rotating casing 32a and the second rotating casing 33a are rotatably connected to each other about the bending axis BA. The second folding restricting member 27 is provided in a casing formed by the first rotating casing 32a and the second rotating casing 33a. The first rotating casing 32a and the second rotating casing 33a are arranged in the width direction. The second folding restricting member 27 is held by the second rotating housing 33a so as to be movable in the width direction. The second folding restricting member 27 is biased toward the first rotation case 32 a in the width direction through the biasing mechanism 35 . The second folding restricting member 27 is positioned so as to straddle both the first rotating case 32a and the second rotating case 33a, thereby allowing the first rotating case 32a and the second rotating case 33a to have the bending axis BA as the center. Relative rotation is restricted. Therefore, by pressing the second folding restricting member 27 into the second rotating housing 33a, the restriction on the bending of the grip 30 can be released.

第1折疊限制部件26及第2折疊限制部件27能夠透過設置於握把30的遠程操作裝置34進行操作。遠程操作裝置34例如具有作為操作桿而構成的操作部34a。操作部34a的操作經由傳遞機構38傳遞至第1折疊限制部件26及第2折疊限制部件27雙方。即,透過操作遠程操作裝置34的操作部34a,能夠解除對第1折疊限制部件26及第2折疊限制部件27雙方的限制。 The first folding restricting member 26 and the second folding restricting member 27 can be operated through the remote control device 34 provided in the grip 30 . The remote operation device 34 has, for example, an operation portion 34a configured as an operation lever. The operation of the operation portion 34 a is transmitted to both the first folding restricting member 26 and the second folding restricting member 27 via the transmission mechanism 38 . That is, by operating the operation part 34a of the remote control device 34, the restrictions on both the first folding restricting member 26 and the second folding restricting member 27 can be released.

在圖7A~圖7C所示的示例中,傳遞機構38具有第1傳遞線材38A、第2傳遞線材38B及中間操作部件38C。中間操作部件38C配置在第1傳遞線材38A及第2傳遞線材38B之間。第1傳遞線材38A在其兩端與遠程操作裝置34的操作部34a和中間操作部件38C連接。第2傳遞線材38B在其兩端與遠程操作裝置34的操作部34a和第1折疊限制部件26連接。中間操作部件38C位於由第1轉動殼體32a及第2轉動殼體33a形成的殼體內。在該殼體內,中間操作部件38C位於在寬度方向上與第2折疊限制部件27相鄰的位置。 In the example shown in FIGS. 7A to 7C , the transmission mechanism 38 includes a first transmission wire 38A, a second transmission wire 38B, and an intermediate operation member 38C. The intermediate operation member 38C is arranged between the first transmission wire 38A and the second transmission wire 38B. The first transmission wire 38A is connected to the operation portion 34a of the remote control device 34 and the intermediate operation member 38C at both ends thereof. The second transmission wire 38B is connected to the operation portion 34a of the remote control device 34 and the first folding restricting member 26 at both ends thereof. The intermediate operation member 38C is located in a casing formed by the first rotating casing 32a and the second rotating casing 33a. In this case, the intermediate operation member 38C is located at a position adjacent to the second folding restricting member 27 in the width direction.

此外,第1傳遞線材38A及第2傳遞線材38B分別配置在未圖示的筒狀部件內。並且,未圖示的筒狀部件的兩端固定於握把30。第1傳遞線材38A及第2傳遞線材38B其兩端部位於筒狀部件外,但以在筒狀部件外不鬆弛的方式調節筒狀部件的配置。因此,根據遠程操作裝置34的操作部34a的操作量而決定中間操作部件38C的動作量及第1折疊限制部件26的動作量。 In addition, the 1st transmission wire 38A and the 2nd transmission wire 38B are respectively arrange|positioned in the cylindrical member which is not shown in figure. In addition, both ends of the cylindrical member (not shown) are fixed to the grip 30 . Both ends of the first transmission wire 38A and the second transmission wire 38B are located outside the tubular member, but the arrangement of the tubular member is adjusted so as not to loosen outside the tubular member. Therefore, the movement amount of the intermediate operation member 38C and the movement amount of the first folding restricting member 26 are determined according to the operation amount of the operation portion 34a of the remote operation device 34 .

中間操作部件38C被保持在第1握把元件32的第1轉動殼體32a內。中間操作部件38C在握把30的長度方向上移動與遠程操作裝置34的操作部34a的操作量相對應的長度。此外,中間操作部件38C具有能夠與設置於第1轉動殼體32a的凸部32b接觸的凸部38Ca。透過使中間操作部件38C的凸部38Ca與 第1轉動殼體32a的凸部32b接觸,中間操作部件38C在第1轉動殼體32a內向寬度方向外側移動。第2折疊限制部件27由彈壓機構35向寬度方向內側彈壓,被朝向中間操作部件38C按壓。透過使中間操作部件38C向寬度方向外側移動,能夠將第2折疊限制部件27推向寬度方向外側從而解除第2折疊限制部件27對握把30的彎曲限制。 The intermediate operation member 38C is held in the first rotation case 32a of the first grip element 32 . The intermediate operation member 38C moves in the longitudinal direction of the grip 30 by a length corresponding to the amount of operation of the operation portion 34a of the remote operation device 34 . Moreover, 38 C of intermediate|middle operation members have the convex part 38Ca which can contact the convex part 32b provided in the 1st rotation case 32a. By making the convex portion 38Ca of the intermediate operation member 38C and the The convex part 32b of the 1st rotation case 32a contacts, and 38 C of intermediate|middle operation members move to the width direction outer side in the 1st rotation case 32a. The second folding restricting member 27 is biased inward in the width direction by the biasing mechanism 35, and is pressed toward the intermediate operation member 38C. By moving the intermediate operation member 38C to the outside in the width direction, the second folding restricting member 27 can be pushed to the outside in the width direction, and the restriction on the bending of the grip 30 by the second folding restricting member 27 can be released.

在圖示的嬰兒車10中,在以第1操作量(參照圖7B)操作遠程操作裝置34的操作部34a的情況下,在由第2折疊限制部件27限制握把30的彎曲的狀態下解除第1折疊限制部件26對握把30相對於第1連桿21的轉動的限制。具體而言,在從圖7A所示的狀態到圖7B所示的狀態為止,以第1操作量操作操作部34a的情況下,能夠經由傳遞機構38將第1折疊限制部件26提起。由此,能夠將第1折疊限制部件26從後腿62的凹部62c提起,並且能夠將第1折疊限制部件26從第4連桿24的切口24a提起。此時,如圖7B所示,中間操作部件38C的凸部38Ca還未與第1轉動殼體32a的凸部32b接觸。因此,中間操作部件38C及第2折疊限制部件27在寬度方向上沒有移動。第2折疊限制部件27位於橫跨第1轉動殼體32a及第2轉動殼體33a的位置,限制握把30的彎曲。 In the stroller 10 shown in the figure, when the operation part 34a of the remote operation device 34 is operated by the first operation amount (see FIG. 7B ), the bending of the grip 30 is restricted by the second folding restricting member 27 . The restriction of the rotation of the grip 30 with respect to the first link 21 by the first folding restricting member 26 is released. Specifically, when the operation part 34a is operated by the first operation amount from the state shown in FIG. 7A to the state shown in FIG. 7B , the first folding restricting member 26 can be lifted via the transmission mechanism 38 . Thereby, the 1st folding restricting member 26 can be lifted up from the recessed part 62c of the rear leg 62, and the 1st folding restricting member 26 can be lifted up from the notch 24a of the 4th link 24. At this time, as shown in FIG. 7B , the convex portion 38Ca of the intermediate operation member 38C is not yet in contact with the convex portion 32b of the first rotating housing 32a. Therefore, the intermediate operation member 38C and the second folding restricting member 27 do not move in the width direction. The second folding restricting member 27 is located across the first pivoting case 32a and the second pivoting case 33a, and restricts the bending of the grip 30 .

接著,在從圖7B所示的狀態到圖7C所示的狀態為止,進一步對操作部34a進行了操作的情況下,能夠經由傳遞機構38將中間操作部件38C進一步提起,從而使中間操作部件38C的凸部38Ca與第2轉動殼體33a的凸部32b接觸。透過凸部38Ca與凸部32b的接觸,能夠使中間操作部件38C向寬度方向外側移動。由此,能夠經由中間操作部件38C將第2折疊限制部件27壓入第2轉動殼體33a內,從而能夠解除對握把30的彎曲限制。也就是說,在從圖7A所示的狀 態到圖7B所示的狀態為止,以比第1操作量大的第2操作量操作遠程操作裝置34的操作部34a情況下,能夠解除第1折疊限制部件26對握把30相對於第1連桿21的轉動的限制,並且能夠解除第2折疊限制部件27對握把30的彎曲的限制。 Next, when the operation part 34a is further operated from the state shown in FIG. 7B to the state shown in FIG. 7C , the intermediate operation member 38C can be further lifted up via the transmission mechanism 38 , so that the intermediate operation member 38C can be moved further. The convex portion 38Ca of the second rotating housing 33a is in contact with the convex portion 32b. The intermediate operation member 38C can be moved to the outer side in the width direction by the contact between the convex portion 38Ca and the convex portion 32b. Thereby, the 2nd folding restricting member 27 can be press-fitted into the 2nd rotation housing 33a via the intermediate|middle operation member 38C, and the bending restriction|limiting of the grip 30 can be cancelled|released. That is, in the state shown in Fig. 7A From the state shown in FIG. 7B , when the operation portion 34a of the remote control device 34 is operated with a second operation amount larger than the first operation amount, the first folding restricting member 26 can release the relative position of the grip 30 to the first folding control member 26 . The rotation of the link 21 is restricted, and the restriction of the bending of the grip 30 by the second folding restricting member 27 can be released.

在上述的一實施方式中,嬰兒車10具有:握把30;座支承體40,與握把30的上下方向的中間部分可轉動地連接並支承嬰幼兒的臀部;第1連桿21,與握把30的下端部分可轉動地連接;前腿60,與第1連桿21可轉動地連接;第2連桿22,與座支承體40及第1連桿21可轉動地連接。根據這樣的一實施方式,能夠將座支承體配置於在前腿與握把的下端部分之間延伸的第1連桿上方的位置。而且,透過能夠進行嬰兒車的折疊動作的第2連桿,能夠從下方支承座支承體。即,能夠將座支承體穩定地保持在較高的位置。由此,能夠有效地保護乘坐於嬰兒車的嬰幼兒免受行走面(路面)的粉塵或溫度等的影響,且能夠有效地改善乘坐舒適度。 In the above-described embodiment, the stroller 10 includes: a handle 30; a seat support body 40 that is rotatably connected to an intermediate portion in the vertical direction of the handle 30 to support the buttocks of the infant; and a first link 21 that The lower end portion of the handle 30 is rotatably connected; the front leg 60 is rotatably connected to the first link 21 ; the second link 22 is rotatably connected to the seat support body 40 and the first link 21 . According to such an embodiment, the seat support body can be arranged at a position above the first link extending between the front leg and the lower end portion of the grip. Furthermore, the seat support body can be supported from below through the second link which can perform the folding operation of the stroller. That is, the seat support body can be stably held at a high position. Thereby, it is possible to effectively protect the infant riding on the stroller from the influence of dust, temperature, etc. on the running surface (road surface), and it is possible to effectively improve the riding comfort.

在上述的一實施方式的具體示例中,握把30可在與座支承體40連接的位置上方的位置彎曲。因此,能夠有效地縮小能夠將座支承體40保持在較高的位置的嬰兒車10在折疊時的尺寸。 In the specific example of one embodiment described above, the handle 30 can be bent at a position above the position where it is connected to the seat support 40 . Therefore, it is possible to effectively reduce the size of the stroller 10 that can hold the seat support body 40 at a high position when folded.

在上述的一實施方式的具體示例中,嬰兒車10還具有:第1折疊限制部件26,被握把30支承,限制握把30相對於第1連桿21的轉動;第2折疊限制部件27,被握把30支承,限制握把30的彎曲;與傳遞機構38,將設置於握把30的遠程操作裝置34的操作傳遞至第1折疊限制部件26及第2折疊限制部件27。在該嬰兒車10中,能夠透過對一個遠程操作裝置34的操作來實現嬰兒車10的展 開狀態與握把30的伸展狀態雙方的解除。因此,能夠提高可縮小折疊操作時的尺寸的嬰兒車10的操作性。 In the specific example of the above-described one embodiment, the stroller 10 further includes: a first folding restricting member 26 supported by the grip 30 and restricting the rotation of the grip 30 relative to the first link 21; and a second folding restricting member 27 , is supported by the grip 30 and restricts the bending of the grip 30 ; and the transmission mechanism 38 transmits the operation of the remote control device 34 provided on the grip 30 to the first folding restricting member 26 and the second folding restricting member 27 . In this stroller 10, the development of the stroller 10 can be realized by operating one remote control device 34. Both the open state and the extended state of the grip 30 are released. Therefore, the operability of the stroller 10 which can be reduced in size during the folding operation can be improved.

在上述的一實施方式的具體示例中,在以第1操作量操作遠程操作裝置34的情況下,在由第2折疊限制部件27限制握把30的彎曲的狀態下,解除由第1折疊限制部件26對握把30相對於第1連桿21的轉動的限制。此外,在以比第1操作量大的第2操作量操作遠程操作裝置34的情況下,解除第1折疊限制部件26對握把30相對於第1連桿21的轉動的限制,並且解除第2折疊限制部件27對握把30的彎曲的限制。即,在開始對遠程操作裝置34的操作後,首先能夠折疊嬰兒車10。之後,透過進一步繼續進行對遠程操作裝置34的操作,能夠使握把30彎曲。因此,能夠根據嬰兒車10的保管空間等,階段性地縮小處於折疊狀態的嬰兒車10的尺寸。此外,由於在嬰兒車10的折疊動作的開始時握把30的彎曲受到限制,因此能夠在握持握把30的同時穩定地折疊嬰兒車10。 In the specific example of the above-described one embodiment, when the remote control device 34 is operated with the first operation amount, in a state where the bending of the grip 30 is restricted by the second folding restricting member 27, the restriction by the first folding is released. The member 26 restricts the rotation of the grip 30 with respect to the first link 21 . In addition, when the remote control device 34 is operated by the second operation amount larger than the first operation amount, the restriction of the rotation of the grip 30 relative to the first link 21 by the first folding restricting member 26 is released, and the first folding control member 26 is released. 2. The folding restricting member 27 restricts the bending of the grip 30. That is, after the operation of the remote control device 34 is started, the stroller 10 can be folded first. After that, the grip 30 can be bent by further continuing to operate the remote control device 34 . Therefore, the size of the stroller 10 in the folded state can be reduced stepwise according to the storage space of the stroller 10 and the like. In addition, since the bending of the handle 30 is restricted at the start of the folding operation of the stroller 10 , the stroller 10 can be stably folded while the handle 30 is grasped.

在上述的一實施方式的具體示例中,在嬰兒車10的側視狀態下,從握把30的可彎曲的位置到上端為止的長度LU比從握把30的可彎曲的位置到下端為止的長度LL長。根據這樣的嬰兒車10,透過使握把30彎曲,能夠顯著地縮小嬰兒車10的折疊尺寸。 In the specific example of the above-described one embodiment, in the side view of the stroller 10, the length LU from the bendable position of the handle 30 to the upper end is greater than the length LU from the bendable position of the handle 30 to the lower end Length LL is long. According to such a stroller 10 , the folding size of the stroller 10 can be significantly reduced by bending the handle 30 .

在上述的一實施方式的具體示例中,嬰兒車10還具有設置在座支承體40上的座席部件15。座席部件15包括安裝於座支承體40與握把30且從側方面向嬰幼兒的側方件16,握把30的可彎曲的位置處於連接有座支承體40的位置與連接有側方件16的位置之間。在這樣的嬰兒車10中,能夠在成為嬰幼兒的 居住空間的高度位置使握把30彎曲。因此,透過使握把30彎曲,能夠顯著地縮小嬰兒車10的折疊尺寸。 In the specific example of the above-described one embodiment, the stroller 10 further includes the seat member 15 provided on the seat support body 40 . The seat member 15 includes a side member 16 that is attached to the seat support body 40 and the handle 30 and faces the infant from the side. The bendable position of the handle 30 is at the position where the seat support body 40 is connected and the side member is connected. 16 positions. In such a stroller 10, it is possible to become an infant The height position of the living space allows the handle 30 to flex. Therefore, by bending the handle 30, the folded size of the stroller 10 can be significantly reduced.

在上述的一實施方式的具體示例中,設置有連結加強機構17,連結在座支承體40的與握把30連接的位置前方的位置和握把30的與座支承體40連接的位置上方的位置之間。在這樣的嬰兒車10中,能夠使用連結加強機構17將座支承體40的與握把30連接的位置前方的位置向上方吊起。透過使用連結加強機構17,能夠將座支承體40更加穩定地支承在較高的位置。 In the specific example of the above-described one embodiment, the connection reinforcement mechanism 17 is provided, and is connected to the seat support body 40 at a position in front of the position connected to the handle 30 and at a position above the position of the handle 30 connected to the seat support body 40 between. In such a stroller 10 , a position in front of the position where the seat support body 40 is connected to the handle 30 can be lifted upward using the connection reinforcement mechanism 17 . By using the connection reinforcement mechanism 17, the seat support body 40 can be supported more stably at a high position.

在上述的一實施方式的具體示例中,嬰兒車10還具有設置在座支承體40上的座席部件15。座席部件15包括安裝於座支承體40與握把30且從側方面向嬰幼兒的側方件16。側方件16構成連結加強機構17。在這樣的嬰兒車10中,能夠由座席部件15將座支承體40的與握把30連接的位置前方的位置向上方吊起。因此,能夠有效地避免加重嬰兒車10,同時能夠將座支承體40更加穩定地支承在較高的位置。 In the specific example of the above-described one embodiment, the stroller 10 further includes the seat member 15 provided on the seat support body 40 . The seat member 15 includes the side member 16 which is attached to the seat support body 40 and the handle 30 and faces the infant from the side. The side pieces 16 constitute the connection reinforcement mechanism 17 . In such a stroller 10 , the seat member 15 can suspend the seat support body 40 in front of the position connected to the handle 30 upward. Therefore, the weight of the stroller 10 can be effectively avoided, and the seat support body 40 can be more stably supported at a high position.

在上述的一實施方式的具體示例中,嬰兒車10還具有:一對後腿62,位於前腿60的後方;後方連結部件64,連結一對後腿62;以及,可彎曲的站立部件70,與前腿60或從前腿60向側方伸出的部件(前方連結部52)和後方連結部件64可轉動地連接。站立部件70在折疊嬰兒車10時彎曲,彎曲的站立部件70與被一對後腿62保持的後輪63接地,從而能夠使折疊的嬰兒車10立起。在這樣的嬰兒車10中,能夠在確保用於實現折疊的連桿構成和座支承體40的配置的自由度的同時,使折疊的嬰兒車10立起。由此,能夠有效地減小折疊的嬰兒車10的保管空間,並且能夠有效地改善折疊的嬰兒車10的處理性。 In the specific example of the above-mentioned one embodiment, the stroller 10 further includes: a pair of rear legs 62 located behind the front legs 60; a rear connecting member 64 connecting the pair of rear legs 62; and a bendable standing member 70 , and is rotatably connected to the front leg 60 or a member (front connecting portion 52 ) extending laterally from the front leg 60 and the rear connecting member 64 . The standing member 70 is bent when the stroller 10 is folded, and the bent standing member 70 is in contact with the rear wheel 63 held by the pair of rear legs 62 , so that the folded stroller 10 can be erected.
