Description

嬰兒車Baby carriage

本發明涉及可擺動握把的折疊式嬰兒車。The invention relates to a folding baby carriage with a swingable handle.

例如，如JP2015-209182A所公開的那樣，在帶嬰幼兒外出時所使用的嬰兒車可供利用。許多嬰兒車考慮到保管時和攜帶時的便利性而可折疊。此外，使得握把可在第1位置與第2位置之間擺動的嬰兒車也廣泛普及。For example, as disclosed in JP2015-209182A, strollers used when taking infants out are available. Many strollers are foldable in consideration of convenience when storing and carrying. In addition, strollers that allow the handle to swing between the first position and the second position are also widely used.

在JP2015-209182A所公開的嬰兒車中，握把可在背面推動位置與面向推動位置之間擺動。在背面推動位置上，握把位於嬰幼兒的背面側，監護人從嬰幼兒的背面側向前推進嬰兒車。另一方面，在面向推動位置上，握把位於面向嬰幼兒的位置，監護人從面向嬰幼兒的一側向前推進嬰兒車。In the stroller disclosed in JP2015-209182A, the handle can swing between a back pushing position and a facing pushing position. In the back push position, the grip is located on the back side of the infant, and the guardian pushes the stroller forward from the back side of the infant. On the other hand, in the pushing position facing the infant, the handle is located at the position facing the infant, and the guardian pushes the stroller forward from the side facing the infant.

然而，在握把可在第1位置與第2位置之間擺動的折疊式嬰兒車中，在握把被配置於第1位置以及第2位置的任一方的情況下，存在嬰兒車意外地變形為折疊狀態的風險。例如，在將握把配置於面向推動位置並且以嬰兒車的後腿側為行進方向的前方的方式使嬰兒車行走的情況下，有時後輪會撞到臺階等從而對後腿施加強烈衝擊。並且，存在以下風險：用於將嬰兒車維持在展開狀態的嬰兒車的構成元件之間的卡合由於施加於後腿的衝擊而意外地解除，嬰兒車意外地成為折疊狀態。或者，即使不至於成為折疊狀態，也存在以下風險：處於展開狀態的嬰兒車的強度降低或者使用了握把的嬰兒車的操作性降低。However, in a folding stroller in which the handle can swing between the first position and the second position, when the handle is arranged in either the first position or the second position, the stroller may be accidentally deformed into folding State risk. For example, when the handle is arranged to face the pushing position and the stroller is walked with the rear leg side of the stroller as the front of the direction of travel, the rear wheel may hit a step or the like, which may impose a strong impact on the rear leg. . In addition, there is a risk that the engagement between the constituent elements of the stroller for maintaining the stroller in the unfolded state is unexpectedly released due to the impact applied to the rear legs, and the stroller unexpectedly enters the folded state. Or, even if it does not become a folded state, there is a risk that the strength of the stroller in the unfolded state is reduced or the operability of the stroller using the grip is reduced.

下面參照附圖所示的一具體例對本發明的一實施方式進行說明。Hereinafter, an embodiment of the present invention will be described with reference to a specific example shown in the drawings.

圖1～圖14是用於說明根據本發明的嬰兒車的一實施方式的圖。其中，在圖1～圖4中示出了嬰兒車的具體例的整體構成。此外，在圖5中示出嬰兒車的一部分。如圖1～圖4所示，本實施方式中的嬰兒車10具有：主體框架12，具有前腿14以及後腿16；握把40，以相對於主體框架12可擺動的方式連接於主體框架12；前輪18，安裝在前腿14；後輪19，安裝在後腿16。其中，主體框架12以及握把40構成嬰兒車主體11。此外，如僅在圖2中以雙點劃線所示地，在嬰兒車主體11中可拆卸地安裝有具有緩衝性的座席件13。嬰幼兒就座或橫臥於該座席件13上。1 to 14 are diagrams for explaining one embodiment of the stroller according to the present invention. Among them, the overall configuration of a specific example of a stroller is shown in FIGS. 1 to 4. In addition, a part of the stroller is shown in FIG. 5. As shown in FIGS. 1 to 4, the stroller 10 in this embodiment has: a main body frame 12 having front legs 14 and rear legs 16; 12; The front wheel 18 is installed on the front leg 14; the rear wheel 19 is installed on the rear leg 16. Among them, the main body frame 12 and the handle 40 constitute the stroller main body 11. In addition, as shown only by the two-dot chain line in FIG. 2, the seat member 13 having cushioning properties is detachably mounted in the stroller main body 11. Infants and toddlers sit or lie down on the seat member 13.

在本實施方式中，握把40可在第1位置與第2位置之間相對於主體框架12擺動。在圖示的例子中，握把40的第1位置是背面推動位置（參照圖1以及圖2），握把40的第2位置是面向推動位置（參照圖3）。如圖2所示，握把40在作為背面推動位置的第1位置上相對於豎直方向傾斜並向後方朝上延伸。在作為背面推動位置的第1位置配置有握把40的情況下，操作者（監護人）從嬰幼兒的背面側握住握把40來操縱嬰兒車10。此時，嬰幼兒能夠在嬰兒車10的行走中朝向行進方向的前方而享受景色。如圖3所示，握把40在作為面向推動位置的第2位置上相對於豎直方向傾斜並向前方朝上延伸。在作為面向推動位置的第2位置配置有握把40的情況下，操作者從面向嬰幼兒的前腿14側的位置握住握把40來操縱嬰兒車10。此時，能夠使嬰兒車10以嬰兒車10的後腿16側成為行進方向的前方的方式行走。In this embodiment, the grip 40 can swing relative to the main body frame 12 between the first position and the second position. In the example shown in the figure, the first position of the grip 40 is the back push position (refer to FIGS. 1 and 2), and the second position of the grip 40 is the facing push position (refer to FIG. 3). As shown in FIG. 2, the grip 40 is inclined with respect to the vertical direction and extends rearward and upward at the first position which is the rear side pushing position. In the case where the grip 40 is arranged at the first position which is the back pushing position, the operator (guardian) holds the grip 40 from the back side of the infant to manipulate the stroller 10. At this time, infants and young children can face the front of the traveling direction and enjoy the scenery while the stroller 10 is walking. As shown in FIG. 3, the grip 40 is inclined with respect to the vertical direction in the 2nd position which is a facing pushing position, and extends forward and upward. When the grip 40 is arranged at the second position facing the pushing position, the operator holds the grip 40 from the position facing the front leg 14 of the infant to manipulate the stroller 10. At this time, the stroller 10 can be made to walk so that the rear leg 16 side of the stroller 10 becomes the front of the traveling direction.

圖示的嬰兒車10（主體框架12）如廣泛普及地那樣構成為可從圖1以及圖2所示的展開狀態向圖4所示的折疊狀態折疊。嬰兒車10（主體框架12）也能夠從折疊狀態展開成展開狀態。在嬰兒車10處於展開狀態的情況下，能夠使握把40相對於主體框架12擺動。The illustrated stroller 10 (main frame 12) is configured to be foldable from the unfolded state shown in FIGS. 1 and 2 to the folded state shown in FIG. 4 as widely spread. The stroller 10 (main frame 12) can also be unfolded from the folded state to the unfolded state. When the stroller 10 is in the unfolded state, the grip 40 can be swung with respect to the main body frame 12.

並且，在本說明書中，沒有特別說明的情況下，相對於嬰兒車及其構成元件的“前”、“後”、“上”、“下”、“前後方向”、“上下方向”以及“寬度方向”的用語表示以乘坐在處於展開狀態的嬰兒車及其構成元件的嬰幼兒為基準的“前”、“後”、“上”、“下”、“前後方向”、“上下方向”以及“寬度方向”。更具體地，“前後方向”是指連結圖1中紙面的左下和右上的方向，且相當於圖2以及圖3中紙面的左右方向。並且，只要沒有特別說明，“前”是指乘坐的嬰幼兒所朝向的一側，圖1中的紙面的左下側以及圖2中的紙面的左側為前側。另一方面，“上下方向”是指與嬰兒車的行走面正交的方向。因此，在行走面為水平面的情況下，“上下方向”是指豎直方向。另外，“寬度方向”是指橫向，是與“前後方向”及“上下方向”的任一方向均正交的方向。進而，“寬度方向內側”表示寬度方向上的靠近嬰兒車中央的一側，在典型的嬰兒車10中，表示與乘坐的嬰幼兒的重心之間在寬度方向上的距離變短的一側。另一方面，“寬度方向外側”表示在寬度方向上遠離嬰兒車的中央的一側。如圖1所示，圖示的嬰兒車10具有整體上以位於寬度方向中心沿前後方向及上下方向的面為中心呈大致對稱的構成。In addition, in this specification, unless otherwise specified, "front", "rear", "upper", "lower", "front-rear direction", "up-down direction" and "in front of the stroller and its components" The term "width direction" means "front", "rear", "upper", "lower", "front-rear direction", "up-down direction" based on infants and toddlers riding in the expanded stroller and its components And "width direction". More specifically, the “front-rear direction” refers to the direction connecting the lower left and upper right of the paper in FIG. 1, and is equivalent to the left-right direction of the paper in FIGS. 2 and 3. In addition, unless otherwise specified, “front” refers to the side toward which the infants and toddlers riding in the seat face, and the lower left side of the paper surface in FIG. 1 and the left side of the paper surface in FIG. 2 are the front side. On the other hand, the "up and down direction" refers to a direction orthogonal to the walking surface of the stroller. Therefore, when the walking surface is a horizontal plane, the "up and down direction" refers to the vertical direction. In addition, the "width direction" refers to the lateral direction, and is a direction orthogonal to either the "front-rear direction" and the "up-down direction". Furthermore, the "width direction inner side" refers to the side close to the center of the stroller in the width direction, and in a typical stroller 10, it refers to the side where the distance in the width direction from the center of gravity of the baby riding in is shortened. On the other hand, "outside in the width direction" means a side away from the center of the stroller in the width direction. As shown in FIG. 1, the illustrated stroller 10 has a generally symmetrical structure centered on a surface in the front-rear direction and the up-down direction at the center in the width direction as a whole.

首先，作為嬰兒車的整體構成而對嬰兒車主體11進行說明。如上所述，嬰兒車主體11具有主體框架12以及握把40。其中，如圖1所示，主體框架12具有分別配置在左右的一對前腿14與分別配置在左右的一對後腿16。主體框架12還具有分別配置在左右的第1連杆L1、第2連杆L2、第3連杆L3以及第4連杆L4。前腿14、後腿16以及第1～第4連杆L1～L4作為使主體框架12構成為可折疊以及可展開的連杆發揮功能。在圖示的例子中，第1連杆L1也作為扶手21發揮功能。即，由扶手21構成第1連杆L1。First, the stroller main body 11 will be described as the overall configuration of the stroller.

The second link L2 is connected to at least one of the third link L3 and the fourth link L4 so as to be rotatable (swingable).

如圖1以及圖5所示，在圖示的例子中，作為構成第3連杆L3的部件，設置有框架件24、固定於框架件24的前連接件25以及後連接件26。框架件24例如由彎曲加工的金屬製管構成。前連接件25以及後連接件26例如由樹脂成形物構成。框架件24具有沿前後方向延伸的一對側部24a與將一對側部24a在前方連結的連結部24b，並呈U字狀。前連接件25的一端部分與前腿14可轉動地連接，另一端部分固定在側部24a的前方部分。後連接件26固定於側部24a的後端部分。在該例子中，由位於右側的框架件24的側部24a與固定於該右側的側部24a的右側的前連接件25以及後連接件26形成右側的第3連杆L3。同樣地，由位於左側的框架件24的側部24a與固定在該左側的側部24a的左側的前連接件25以及後連接件26形成左側的第3連杆L3。As shown in FIGS. 1 and 5, in the example shown in the drawings, as members constituting the third link L3, a frame member 24, a front connector 25 and a rear connector 26 fixed to the frame member 24 are provided. The frame member 24 is composed of, for example, a bent metal pipe. The front link 25 and the rear link 26 are composed of, for example, a resin molded product. The frame member 24 has a pair of side portions 24a extending in the front-rear direction and a connecting portion 24b that connects the pair of side portions 24a forward, and has a U-shape. One end portion of the front connecting member 25 is rotatably connected to the front leg 14, and the other end portion is fixed to the front portion of the side portion 24a. The rear connector 26 is fixed to the rear end portion of the side portion 24a. In this example, the side portion 24a of the frame member 24 located on the right side and the right front link 25 and the rear link 26 fixed to the right side portion 24a form the third link L3 on the right side. Similarly, the side portion 24a of the frame member 24 located on the left side, the front connector 25 and the rear connector 26 fixed to the left side of the left side portion 24a form the third link L3 on the left side.

如圖5所示，在圖示的例子中，第4連杆L4具有可轉動地連接於後腿16的主軸件28與固定於主軸件28的上端部分的端部件29。主軸件28例如由金屬製管構成。端部件29例如由樹脂成形物構成。主軸件28在下端部分與後腿16的中間部分可轉動地連接。端部件29與第二連杆L2以及第三連杆L3可轉動地連接。在圖示的例子中，第2連杆L2、第3連杆L3以及第4連杆L4使用同一軸部件30可相互轉動地連接。該軸部件30貫通第2連杆L2的主連杆件22、第4連杆L4的端部件29、以及形成第3連杆L3的後連接件26。根據該構成，第2連杆L2、第3連杆L3以及第4連杆L4能夠以與軸部件30的中心軸線一致的軸線30x為中心相互轉動。As shown in FIG. 5, in the illustrated example, the fourth link L4 has a main shaft 28 rotatably connected to the rear leg 16 and an end member 29 fixed to the upper end portion of the main shaft 28. The main shaft 28 is composed of, for example, a metal pipe. The end member 29 is made of, for example, a resin molded product. The main shaft member 28 is rotatably connected with the middle portion of the rear leg 16 at the lower end portion. The end member 29 is rotatably connected with the second link L2 and the third link L3. In the example shown in the figure, the second link L2, the third link L3, and the fourth link L4 are rotatably connected to each other using the same shaft member 30. The shaft member 30 penetrates the main link member 22 of the second link L2, the end member 29 of the fourth link L4, and the rear link 26 that forms the third link L3. According to this configuration, the second link L2, the third link L3, and the fourth link L4 can mutually rotate around the axis 30x that coincides with the center axis of the shaft member 30.

此外，如圖1～圖3所示，圖示的嬰兒車10的主體框架12進一步具有基底框架31以及上方框架32、連結基底框架31與上方框架32的連結框架33。基底框架31以及上方框架32均形成為U字狀。並且，在圖示的嬰兒車10中，在框架件24以及基底框架31中張設有基底布件34（僅在圖2中圖示）。基底布件34與框架件24、基底框架31、上方框架32以及連結框架33共同支承緩衝性的座席件13（僅在圖2中用雙點劃線圖示）。另外，在圖4中，省略了基底框架31、上方框架32以及連結框架33的圖示。In addition, as shown in FIGS. 1 to 3, the main body frame 12 of the illustrated stroller 10 further includes a base frame 31 and an upper frame 32, and a connection frame 33 that connects the base frame 31 and the upper frame 32. Both the base frame 31 and the upper frame 32 are formed in a U-shape. In addition, in the stroller 10 shown in the figure, the frame member 24 and the base frame 31 are provided with a base cloth member 34 (only shown in FIG. 2 ). The base cloth member 34 and the frame member 24, the base frame 31, the upper frame 32, and the connecting frame 33 jointly support the cushioning seat member 13 (only shown with a two-dot chain line in FIG. 2). In addition, in FIG. 4, illustration of the base frame 31, the upper frame 32, and the connection frame 33 is omitted.

在圖示的例子中，框架件24、基底框架31、上方框架32、連結框架33以及基底布件34構成座席支承體，支承座席件13。其中，基底布件34的一部分以及框架件24構成支承嬰幼兒的臀部的座部支承體。此外，基底布件34的一部分以及基底框架31構成支承嬰幼兒的背部的背部支承體。In the example shown in the figure, the frame member 24, the base frame 31, the upper frame 32, the connecting frame 33, and the base cloth member 34 constitute a seat support body and support the seat member 13. Among them, a part of the base cloth member 34 and the frame member 24 constitute a seat support body that supports the buttocks of infants. In addition, a part of the base fabric 34 and the base frame 31 constitute a back support body that supports the back of an infant.

基底框架31在其兩端部被軸部件30貫通（參照圖5）。並且，基底框架31相對於框架件24或其它構成元件可轉動（可擺動）。透過使基底框架31相對於框架件24擺動，可進行座席件13的斜躺。上方框架32在其兩端部與第1連杆L1的後端部分可轉動（可擺動）地連接。上方框架32相對於第1連杆L1的轉動軸線位於與第2連杆L2相對於第1連杆L1的轉動軸線相同的線上。在基底框架31以及上方框架32之間，在寬度方向上隔開地設置有一對連結框架33。連結框架33在其兩端與基底框架31以及上方框架32可轉動地連接。The base frame 31 is penetrated by the shaft member 30 at the both ends (refer FIG. 5). In addition, the base frame 31 is rotatable (swingable) relative to the frame member 24 or other constituent elements. By swinging the base frame 31 relative to the frame member 24, the seat member 13 can be reclined. The upper frame 32 is rotatably (swingable) connected to the rear end portion of the first link L1 at both ends thereof. The rotation axis of the upper frame 32 with respect to the first link L1 is located on the same line as the rotation axis of the second link L2 with respect to the first link L1. Between the base frame 31 and the upper frame 32, a pair of connection frames 33 are provided spaced apart in the width direction. The connecting frame 33 is rotatably connected with the base frame 31 and the upper frame 32 at both ends thereof.

如圖1所示，主體框架12具有連結在一對前腿14間的前方連結件15、與連結在一對後腿16間的後方連結件17作為在寬度方向延伸的構成元件。其中，在圖示的例子中，前方連結件15在一對前輪18之間延伸，後方連結件17在一對後輪19之間延伸。前方連結件15作為腿踏發揮功能。此外，在一對後連接件26之間設置有中央連結件27。透過前方連結件15、後方連結件17以及中央連結件27，能夠抑制嬰兒車10向寬度方向的變形。進而，在一對第1連杆L1之間可拆卸地設置有具有撓性的保護部件38。As shown in FIG. 1, the main body frame 12 has a front connector 15 connected between the pair of front legs 14 and a rear connector 17 connected between the pair of rear legs 16 as constituent elements extending in the width direction. Among them, in the example shown in the figure, the front link 15 extends between the pair of front wheels 18, and the rear link 17 extends between the pair of rear wheels 19. The front link 15 functions as a leg step. In addition, a central link 27 is provided between the pair of rear links 26. The front connection piece 15, the rear connection piece 17, and the center connection piece 27 can suppress the deformation of the stroller 10 in the width direction. Furthermore, a protective member 38 having flexibility is detachably provided between the pair of first links L1.

由以上的構成組成的主體框架12如後所述，能夠透過使構成元件動作來折疊。另一方面，在主體框架12設置有用於限制構成元件間的相對動作的機構。透過設置該機構，能夠有效地防止意外的折疊動作。The main body frame 12 composed of the above configuration can be folded by operating the constituent elements as described later. On the other hand, the main body frame 12 is provided with a mechanism for restricting the relative movement between the constituent elements. By providing this mechanism, accidental folding actions can be effectively prevented.

具體而言，如圖6以及圖7所示，在主體框架12設置有限制嬰兒車10從展開狀態向折疊狀態的折疊動作的狀態維持部件50。狀態維持部件50能夠在限制嬰兒車10的折疊動作的限制位置（參照圖6）與可進行嬰兒車10的折疊動作的解除位置（參照圖7）之間移動。在圖示的例子中，狀態維持部件50被第2連杆L2的主連杆件22支承。在限制位置與解除位置之間的狀態維持部件50的移動成為沿著主連杆件22的長度方向的移動。Specifically, as shown in FIGS. 6 and 7, the main body frame 12 is provided with a state maintaining member 50 that restricts the folding operation of the stroller 10 from the unfolded state to the folded state. The state maintaining member 50 can move between a restriction position (refer to FIG. 6) that restricts the folding operation of the stroller 10 and a release position (refer to FIG. 7) where the folding operation of the stroller 10 can be performed. In the example shown in the figure, the state maintaining member 50 is supported by the main link 22 of the second link L2. The movement of the state maintenance member 50 between the restricted position and the released position becomes a movement along the longitudinal direction of the main link 22.

如圖7以及圖8所示，狀態維持部件50具有安裝在主連杆件22的主體部51與從主體部51突出的限制卡合突起52以及承接板53。限制卡合突起52從主體部51向寬度方向內側突出。另一方面，在第4連杆L4的端部件29形成有可與限制卡合突起52卡合的限制卡合凹部29a。如圖6所示，在狀態維持部件50相對於第2連杆L2向下方滑動的情況下，狀態維持部件50的限制卡合突起52被收納在第4連杆L4的限制卡合凹部29a內。在圖6所示的狀態下，對狀態維持部件50進行支承的第2連杆L2和與狀態維持部件50卡合的第4連杆L4不能相對轉動。因此，在狀態維持部件50的限制卡合突起52與第4連杆L4的限制卡合凹部29a卡合的情況下，嬰兒車10維持在展開的狀態，不能折疊嬰兒車10。即，圖6所示的狀態維持部件50的位置是狀態維持部件50的限制位置。As shown in FIGS. 7 and 8, the state maintaining member 50 has a main body portion 51 attached to the main link 22, a restricting engagement protrusion 52 protruding from the main body portion 51, and a receiving plate 53. The restricting engagement protrusion 52 protrudes inward in the width direction from the main body portion 51. On the other hand, the end member 29 of the fourth link L4 is formed with a restricting engagement recess 29 a that can engage with the restricting engagement protrusion 52. As shown in FIG. 6, when the state maintaining member 50 slides downward with respect to the second link L2, the restricting engagement protrusion 52 of the state maintaining member 50 is accommodated in the restricting engagement recess 29a of the fourth link L4 . In the state shown in FIG. 6, the second link L2 supporting the state maintaining member 50 and the fourth link L4 engaged with the state maintaining member 50 cannot rotate relatively. Therefore, when the restricting engagement protrusion 52 of the state maintaining member 50 is engaged with the restricting engagement recess 29a of the fourth link L4, the stroller 10 is maintained in the unfolded state, and the stroller 10 cannot be folded. That is, the position of the state maintaining member 50 shown in FIG. 6 is the restriction position of the state maintaining member 50.

另一方面，如圖7所示，若狀態維持部件50相對於第2連杆L2向上方滑動，則限制卡合突起52從第4連杆L4的限制卡合凹部29a脫出。並且，若限制卡合突起52與限制卡合凹部29a的卡合被解除，則第2連杆L2以及第四連杆L4變得可相對轉動，變得可折疊嬰兒車10。即，圖7所示的狀態維持部件50的位置是狀態維持部件50的解除位置。On the other hand, as shown in FIG. 7, when the state maintaining member 50 slides upward with respect to the second link L2, the restricting engagement protrusion 52 will escape from the restricting engagement recess 29a of the fourth link L4. Then, when the engagement of the restricting engagement protrusion 52 and the restricting engagement recess 29a is released, the second link L2 and the fourth link L4 become relatively rotatable, and the stroller 10 becomes foldable. That is, the position of the state maintaining member 50 shown in FIG. 7 is the release position of the state maintaining member 50.

另外，狀態維持部件50的主體部51由未圖示的施力部件（例如彈簧）從解除位置（參照圖7）朝向限制位置（參照圖6）施力。透過像這樣地使用來自施力部件的作用力，只要不積極地施加外力，就可以更可靠地限制嬰兒車10的折疊動作。即，透過使用施力部件，能夠有效地防止因誤動作而意外地開始嬰兒車10的折疊動作。In addition, the main body portion 51 of the state maintaining member 50 is urged from the release position (refer to FIG. 7) toward the restriction position (refer to FIG. 6) by a urging member (for example, a spring) not shown. By using the urging force from the urging member in this way, as long as the external force is not actively applied, the folding operation of the stroller 10 can be restricted more reliably. That is, by using the urging member, it is possible to effectively prevent the accidental start of the folding operation of the stroller 10 due to a malfunction.

進而，如圖8所示，在圖示的例子中，在第2連杆L2的主連杆件22的內腔配置有後腿卡合部件54。後腿卡合部件54相對於狀態維持部件50固定。因此，後腿卡合部件54隨著狀態維持部件50在限制位置（參照圖6）與解除位置（參照圖7）之間的移動，沿主連杆件22的長度方向移動。後腿卡合部件54的下端部54a在狀態維持部件50處於限制位置時，從主連杆件22的下端突出。並且，在嬰兒車10處於展開狀態的情況下，上述下端部54a被收納在設置於固定在後腿16的第2連杆支承部件16a的上表面的凹部。由此，防止第2連杆L2與後腿16的相對轉動。因此，在狀態維持部件50處於限制位置的情況下，也可透過後腿卡合部件54以及第2連杆支承部件16a維持嬰兒車10展開的狀態。另一方面，後腿卡合部件54在狀態維持部件50處於解除位置時，其全部被收納在主連杆件22內。由此，第2連杆L2與後腿16變得可相對轉動，變得可折疊嬰兒車10。Furthermore, as shown in FIG. 8, in the illustrated example, the rear leg engagement member 54 is arranged in the inner cavity of the main link 22 of the second link L2. The rear leg engagement member 54 is fixed to the state maintaining member 50. Therefore, the rear leg engagement member 54 moves along the longitudinal direction of the main link 22 in accordance with the movement of the state maintaining member 50 between the restriction position (refer to FIG. 6) and the release position (refer to FIG. 7 ). The lower end 54 a of the rear leg engagement member 54 protrudes from the lower end of the main link 22 when the state maintaining member 50 is in the restricting position. In addition, when the stroller 10 is in the unfolded state, the lower end 54 a is housed in a recess provided on the upper surface of the second link support member 16 a fixed to the rear leg 16. Thereby, the relative rotation of the second link L2 and the rear leg 16 is prevented. Therefore, even when the state maintaining member 50 is in the restricting position, the expanded state of the stroller 10 can be maintained through the rear leg engagement member 54 and the second link support member 16a. On the other hand, when the rear leg engagement member 54 is in the release position of the state maintaining member 50, all of them are housed in the main link 22. Thereby, the second link L2 and the rear leg 16 become relatively rotatable, and the stroller 10 becomes foldable.

握把40可擺動地連結於以上說明的主體框架12。在圖示的例子中，握把40具有可擺動地安裝在主體框架12的握把主體41、設置在握把主體41的保持體42、遠程操作裝置43以及操作部件60。在圖示的嬰兒車主體11中，握把40可在側視狀態下向垂直軸的後方傾斜的第1位置（背面推動位置）與向垂直軸的前方傾斜的第2位置（面向推動位置）之間擺動。The grip 40 is swingably connected to the main body frame 12 described above. In the example shown in the figure, the grip 40 includes a grip main body 41 swingably attached to the main body frame 12, a holder 42 provided on the grip main body 41, a remote operation device 43, and an operating member 60. In the stroller body 11 shown in the figure, the handle 40 can be tilted to the rear of the vertical axis in a first position (rear pushing position) and a second position (facing the pushing position) tilted to the front of the vertical axis in a side view. Swing between.

如圖1所示，握把主體41包括相互大致平行地延伸的一對軸部41a與連結在一對軸部41a之間的中間部41b。握把主體41作為整體具有大致U字狀的形狀。握把40在U字的兩端部與主體框架12可轉動（可擺動）地連接。在圖示的例子中，握把主體41使用軸部件30與主體框架12可轉動地連接。因此，第2連杆L2、第3連杆L3、第4連杆L4、基底框架31以及握把40能夠以根據軸部件30劃出的同一軸線30x為中心相互相對地轉動。As shown in Fig. 1, the grip body 41 includes a pair of shaft portions 41a extending substantially parallel to each other, and an intermediate portion 41b connected between the pair of shaft portions 41a. The grip main body 41 has a substantially U-shaped shape as a whole. The grip 40 is rotatably (swinging) connected to the main frame 12 at both ends of the U shape. In the example shown in the figure, the grip main body 41 is rotatably connected to the main body frame 12 using the shaft member 30. Therefore, the second link L2, the third link L3, the fourth link L4, the base frame 31, and the grip 40 can rotate relative to each other about the same axis 30x drawn by the shaft member 30 as the center.

保持體42設置在握把主體41的軸部41a上。保持體42可沿軸部41a的長度方向在軸部41a上移動。握把40具有未圖示的施力部件（例如彈簧），施力部件將保持體42朝向下方按壓。保持體42可與設置於主體框架12的第1位置保持部36以及第2位置保持部37卡合。如圖3所示，第1位置保持部36設置於第2連杆L2。此外，如圖2所示，第2位置保持部37設置於第1連杆L1。還如圖9以及圖10所示，各位置保持部36、37作為在前端具有擴徑部分的突起向寬度方向外側突出。The holding body 42 is provided on the shaft portion 41 a of the grip main body 41. The holding body 42 is movable on the shaft portion 41a along the length direction of the shaft portion 41a. The grip 40 has an unillustrated urging member (for example, a spring), and the urging member presses the holding body 42 downward. The holding body 42 can be engaged with the first position holding portion 36 and the second position holding portion 37 provided in the main body frame 12. As shown in FIG. 3, the 1st position holding part 36 is provided in the 2nd link L2. Moreover, as shown in FIG. 2, the 2nd position holding part 37 is provided in the 1st link L1. As also shown in FIG. 9 and FIG. 10, each position holding portion 36 and 37 protrudes outward in the width direction as a protrusion having an enlarged diameter portion at the tip.

在圖示的例子中，一對保持體42被支承在握把主體41的各軸部41a。保持體42可沿握把主體41中的設置有該保持體42的部分的長度方向相對於握把主體41移動。如圖2以及圖11所示，在握把主體41的各軸部41a固定有止動件41c。止動件41c形成為比軸部41a更為擴徑的部分。止動件41c規定保持體42的可移動範圍。保持體42能夠在止動件41c的上方的區域沿軸部41a的長度方向移動。In the example shown in the figure, the pair of holding bodies 42 are supported by the shaft portions 41 a of the grip main body 41. The holding body 42 can move relative to the grip body 41 along the length direction of the portion of the grip body 41 where the holding body 42 is provided. As shown in FIG. 2 and FIG. 11, a stopper 41 c is fixed to each shaft portion 41 a of the grip body 41. The stopper 41c is formed as a part with a larger diameter than the shaft portion 41a. The stopper 41 c defines the movable range of the holding body 42. The holding body 42 can move in the longitudinal direction of the shaft portion 41a in an area above the stopper 41c.

如圖11所示，保持體42具有供軸部41a通過的筒狀主體部45、被筒狀主體部45支承的卡合部46以及引導部47。如圖11所示，卡合部46具有向下方開口的承接部46a。如圖12以及圖14所示，透過使卡合部46從上方覆蓋在位置保持部36、37，保持體42與位置保持部36、37向與軸部41a的長度方向正交的方向的相對移動被限制，握把40被保持在第1位置或第2位置。As shown in FIG. 11, the holding body 42 has a cylindrical main body portion 45 through which the shaft portion 41 a passes, an engagement portion 46 supported by the cylindrical main body portion 45, and a guide portion 47. As shown in FIG. 11, the engaging portion 46 has a receiving portion 46a that opens downward. As shown in FIGS. 12 and 14, by covering the engagement portion 46 on the position holding portions 36 and 37 from above, the holding body 42 and the position holding portions 36 and 37 face each other in a direction orthogonal to the longitudinal direction of the shaft portion 41a. The movement is restricted, and the grip 40 is held in the first position or the second position.

如圖11所示，各保持體42具有位於卡合部46的兩側的一對引導部47。如圖12～圖14所示，筒狀主體部45位於在前後方向上隔開的一對引導部47之間。在握把40在第1位置與第2位置之間擺動時，例如如圖13所示，與卡合部46相鄰地設置的引導部47比該卡合部46先與位置保持部36、37接觸。引導部47具有與位置保持部36、37接觸的引導面47a。引導面47a為傾斜面。透過使引導面47a與位置保持部36、37接觸，保持體42沿軸部41a的長度方向與止動件41c隔開而移動至上側。然後，克服施力部件的作用力而移動至上方的保持體42以覆蓋第1位置保持部36或第2位置保持部37的方式移動至下方，由此能夠使保持體42與第1位置保持部36或第2位置保持部37卡合。As shown in FIG. 11, each holding body 42 has a pair of guide portions 47 located on both sides of the engaging portion 46. As shown in FIGS. 12-14, the cylindrical main body part 45 is located between a pair of guide parts 47 spaced apart in the front-back direction. When the grip 40 swings between the first position and the second position, as shown in, for example, FIG. touch. The guide portion 47 has a guide surface 47 a that is in contact with the position holding portions 36 and 37. The guide surface 47a is an inclined surface. By bringing the guide surface 47a into contact with the position holding portions 36 and 37, the holding body 42 is spaced apart from the stopper 41c in the longitudinal direction of the shaft portion 41a and moved to the upper side. Then, the holding body 42 that has moved upward against the force of the urging member moves downward so as to cover the first position holding portion 36 or the second position holding portion 37, whereby the holding body 42 and the first position can be held. The portion 36 or the second position holding portion 37 engages.

如圖12所示，保持體42與第1位置保持部36卡合，由此握把40相對於主體框架12的擺動被限制，能夠如圖2所示地將握把40維持在第1位置。此外，如圖14所示，保持體42與第2位置保持部37卡合，由此握把40相對於主體框架12的擺動被限制，能夠如圖3所示地將握把40維持在第2位置。As shown in FIG. 12, the holding body 42 is engaged with the first position holding portion 36, whereby the swing of the grip 40 with respect to the main body frame 12 is restricted, and the grip 40 can be maintained in the first position as shown in FIG. . In addition, as shown in FIG. 14, the holding body 42 is engaged with the second position holding portion 37, whereby the swing of the grip 40 with respect to the main body frame 12 is restricted, and the grip 40 can be maintained in the second position as shown in FIG. 2 location.

具有以上構成的嬰兒車主體11透過操作保持體42從而使握把40相對於主體框架12擺動，能夠使握把40在第1位置以及第2位置之間變化。具體而言，在使握把40從第1位置（背面推動位置）向第2位置（面向推動位置）移動的情況下，沿著握把主體41的軸部41a的長度方向將保持體42向上方提起。若保持體42相對於握把主體41移動，則收納於保持體42的承接部46a的第1位置保持部36從承接部46a脫出。由此，握把40與主體框架12的卡合被解除，握把40變得相對於主體框架12可擺動。The stroller body 11 having the above-mentioned structure can swing the grip 40 with respect to the main body frame 12 by operating the holding body 42, and the grip 40 can be changed between the first position and the second position. Specifically, when the grip 40 is moved from the first position (rear pushing position) to the second position (facing the pushing position), the holding body 42 is moved upward along the longitudinal direction of the shaft portion 41a of the grip main body 41 Fang mentioned. When the holding body 42 moves with respect to the grip main body 41, the first position holding portion 36 housed in the receiving portion 46a of the holding body 42 comes out of the receiving portion 46a. Thereby, the engagement between the grip 40 and the main body frame 12 is released, and the grip 40 becomes swingable with respect to the main body frame 12.

若握把40到達第2位置的附近，則第2位置保持部37開始與保持體42的引導面47a接觸。透過第2位置保持部37抵接於引導面47a，從而沿著軸部41a的長度方向將保持體42向上方推起。若握把40到達第2位置，則解除第2位置保持部37與引導面47a的接觸。並且，保持體42透過來自施力部件的作用力，自動地沿著軸部41a的長度方向移動至下方，保持體42的承接部46a覆蓋在第2位置保持部37。由此，握把40與主體框架12的相對擺動被限制，握把40被保持在第2位置。When the grip 40 reaches the vicinity of the second position, the second position holding portion 37 starts to come into contact with the guide surface 47 a of the holding body 42. When the second position holding portion 37 abuts on the guide surface 47a, the holding body 42 is pushed upward along the longitudinal direction of the shaft portion 41a. When the grip 40 reaches the second position, the contact between the second position holding portion 37 and the guide surface 47a is released. In addition, the holding body 42 automatically moves downward along the longitudinal direction of the shaft portion 41 a through the urging force from the urging member, and the receiving portion 46 a of the holding body 42 covers the second position holding portion 37. Thereby, the relative swing of the grip 40 and the main body frame 12 is restricted, and the grip 40 is held in the second position.

在使握把40從第2位置向第1位置擺動的情況下，實施與上述的使握把40從第1位置向第2位置擺動的情況大致相同的操作。即，首先，將握把40的保持體42向上方提起，接著，使握把40從第2位置移動至第1位置即可。In the case of swinging the grip 40 from the second position to the first position, substantially the same operation as in the case of swinging the grip 40 from the first position to the second position described above is performed. That is, first, the holding body 42 of the grip 40 may be lifted upward, and then, the grip 40 may be moved from the second position to the first position.

接著，對操作部件60進行說明。如圖6以及圖7所示，操作部件60可動作地設置在握把主體41。如圖6以及圖7所示，操作部件60透過進行動作而使狀態維持部件50動作。即，操作部件60隨著狀態維持部件50的設置而設置。Next, the operation member 60 will be described. As shown in FIGS. 6 and 7, the operating member 60 is movably provided on the grip body 41. As shown in FIGS. 6 and 7, the operating member 60 operates to operate the state maintaining member 50. That is, the operating member 60 is provided in accordance with the installation of the state maintaining member 50.

操作部件60能夠在圖6所示的非操作位置與圖7所示的操作位置之間沿著握把主體41的軸部41a中的設置有操作部件60的部分的長度方向移動。操作部件60由被收納在握把40的軸部41a的未圖示的施力部件（例如彈簧）從操作位置側向非操作位置側施力。即，操作部件60在未被施加外力的情況下，利用來自施力部件的作用力從而位於操作位置的下方的非操作位置。此外，在圖示的例子中，操作部件60透過未圖示的操作傳遞件與設置在握把40的中間部41b的遠程操作裝置43（參照圖1）連結。然後，透過對遠程操作裝置43進行操作，能夠使操作部件60從操作位置向非操作位置移動。The operating member 60 can move between the non-operating position shown in FIG. 6 and the operating position shown in FIG. 7 along the longitudinal direction of the portion where the operating member 60 is provided in the shaft portion 41 a of the grip body 41. The operating member 60 is urged from the operating position side to the non-operating position side by an unillustrated urging member (for example, a spring) housed in the shaft portion 41 a of the grip 40. That is, when no external force is applied, the operating member 60 utilizes the force from the urging member to be located in the non-operating position below the operating position. In addition, in the example shown in the figure, the operating member 60 is connected to the remote operating device 43 (refer to FIG. 1) provided in the middle portion 41 b of the grip 40 through an operation transmitting member (not shown). Then, by operating the remote operating device 43, the operating member 60 can be moved from the operating position to the non-operating position.

如圖8所示，操作部件60具有操作基部61與從操作基部61突出的操作突出部62。如圖6以及圖7所示，操作基部61安裝在握把主體41的軸部41a。根據圖6及圖7的比較可以理解，操作基部61可沿握把主體41的軸部41a的長度方向相對於該軸部41a滑動。此外，操作突出部62從操作基部61向寬度方向內側伸出。另一方面，如圖6以及圖7所示，狀態維持部件50的承接板53從主體部51向寬度方向外側伸出。As shown in FIG. 8, the operating member 60 has an operating base 61 and an operating protrusion 62 protruding from the operating base 61. As shown in FIGS. 6 and 7, the operation base 61 is attached to the shaft portion 41 a of the grip body 41. It can be understood from the comparison of FIG. 6 and FIG. 7 that the operation base 61 can slide relative to the shaft portion 41 a of the grip main body 41 along the longitudinal direction of the shaft portion 41 a. In addition, the operation protrusion 62 protrudes from the operation base 61 inward in the width direction. On the other hand, as shown in FIGS. 6 and 7, the receiving plate 53 of the state maintaining member 50 protrudes outward in the width direction from the main body portion 51.

在握把40位於第1位置時，如圖6所示，操作部件60從沿著主連杆件22的長度方向的下側面向狀態維持部件50的承接板53。並且，當操作部件60從非操作位置向操作位置移動時，操作突出部62從下方抵接於承接板53，將狀態維持部件50從限制位置朝向解除位置推起。即，在握把40配置於第1位置的情況下，透過使操作部件60從非操作位置向操作位置移動，能夠使狀態維持部件50從限制位置向解除位置移動。由此，第2連杆L2相對於第4連杆L4可相對轉動。另外，在握把40位於第2位置的情況下，在沿著主連杆件22的長度方向的方向上，操作部件60不面向承接板53。因此，即使操作部件60從圖6所示的非操作位置移動到圖7所示的操作位置，狀態維持部件50也停留在圖6的限制位置。When the grip 40 is in the first position, as shown in FIG. 6, the operating member 60 faces the receiving plate 53 of the state maintaining member 50 from the lower side along the longitudinal direction of the main link 22. In addition, when the operating member 60 moves from the non-operating position to the operating position, the operating protrusion 62 abuts against the receiving plate 53 from below, and pushes the state maintaining member 50 from the restricting position to the releasing position. That is, when the grip 40 is arranged in the first position, by moving the operating member 60 from the non-operating position to the operating position, the state maintaining member 50 can be moved from the restricting position to the releasing position. Thereby, the second link L2 is relatively rotatable with respect to the fourth link L4. In addition, when the grip 40 is in the second position, the operating member 60 does not face the receiving plate 53 in the direction along the longitudinal direction of the main link 22. Therefore, even if the operating member 60 moves from the non-operating position shown in FIG. 6 to the operating position shown in FIG. 7, the state maintaining member 50 stays at the restricting position of FIG. 6.

具有以上的構成的嬰兒車主體11能夠透過使各構成部件相對轉動而折疊。具體而言，首先，在嬰兒車10的折疊動作之前，將握把40配置於第1位置，進而操作遠程操作裝置43，使操作部件60從非操作位置向操作位置移動。由此，狀態維持部件50從限制位置移動至解除位置，狀態維持部件50與第4連杆L4的卡合被解除。The stroller main body 11 having the above-mentioned structure can be folded by relatively rotating each component. Specifically, first, prior to the folding operation of the stroller 10, the grip 40 is arranged in the first position, and the remote operation device 43 is further operated to move the operation member 60 from the non-operation position to the operation position. Thereby, the state maintaining member 50 moves from the restriction position to the release position, and the engagement between the state maintaining member 50 and the fourth link L4 is released.

在該狀態下，使用握把40將第2連杆L2暫時向後上方提起然後降下，由此使第4連杆L4相對於後腿16在圖2中沿順時針方向轉動。隨著該操作，第1連杆L1以及第3連杆L3相對於第2連杆L2在圖2中沿順時針方向轉動。透過這樣的操作，在側視狀態下，第2連杆L2與前腿14大致平行地配置，並且握把40相對於主體框架12的擺動軸線30x的位置降下。如上所述，能夠折疊嬰兒車10。在圖4的折疊後的狀態下，能夠縮小嬰兒車10的沿前後方向以及上下方向的尺寸。另一方面，將嬰兒車10從折疊狀態展開只要執行與上述折疊操作相反的步驟即可。In this state, the second link L2 is temporarily lifted backward and upward using the grip 40 and then lowered, thereby rotating the fourth link L4 in the clockwise direction in FIG. 2 with respect to the rear leg 16. With this operation, the first link L1 and the third link L3 rotate in the clockwise direction in FIG. 2 with respect to the second link L2. Through such an operation, in a side view state, the second link L2 is arranged substantially parallel to the front leg 14, and the position of the grip 40 with respect to the swing axis 30x of the main body frame 12 is lowered. As described above, the stroller 10 can be folded. In the folded state of FIG. 4, the size of the stroller 10 in the front-rear direction and the vertical direction can be reduced. On the other hand, to unfold the stroller 10 from the folded state, it is only necessary to perform the steps opposite to the above-mentioned folding operation.

另外，在以下情況下，有時後輪19會撞到臺階等從而對後腿16施加強烈衝擊：在處於展開狀態的嬰兒車10中，握把40配置於第2位置（面向推動位置），使嬰兒車10的後腿16側成為行進方向的前方從而使嬰兒車10行走。若對後腿16施加強烈衝擊，則存在狀態維持部件50向上方移動、或者第4連杆L4與後腿16一起旋轉等從而使限制卡合突起52從限制卡合凹部29a脫出的風險。並且，存在嬰兒車10被意外地折疊的風險。或者，即使不至於使嬰兒車10被折疊，也存在以下風險：透過限制卡合突起52從限制卡合凹部29a脫出，處於展開狀態的主體框架12的強度降低，或者握把40相對於主體框架12的位置發生偏離（特別是握把40相對於主體框架12向下方移動），使用了握把40的嬰兒車10的操作性降低。In addition, in the following cases, the rear wheel 19 may hit a step or the like to exert a strong impact on the rear leg 16: in the stroller 10 in the expanded state, the grip 40 is arranged in the second position (facing the pushing position), The side of the rear leg 16 of the stroller 10 is set to the front of the traveling direction, and the stroller 10 is allowed to walk. If a strong impact is applied to the rear leg 16, there is a risk that the state maintaining member 50 moves upward, or the fourth link L4 rotates together with the rear leg 16, and the restricting engagement protrusion 52 may escape from the restricting engagement recess 29a. Also, there is a risk that the stroller 10 is accidentally folded. Or, even if the stroller 10 is not folded, there is a risk that through the restricting engagement protrusion 52 coming out of the restricting engagement recess 29a, the strength of the main body frame 12 in the unfolded state is reduced, or the grip 40 is relative to the main body. The position of the frame 12 is deviated (in particular, the grip 40 moves downward with respect to the main body frame 12), and the operability of the stroller 10 using the grip 40 is reduced.

考慮到上述方面，本實施方式的嬰兒車10為了抑制以下情況進行了精心設計：在握把40配置於第2位置（面向推動位置）時，處於展開狀態的嬰兒車10意外地成為折疊狀態，或者即使不至於成為折疊狀態，主體框架12的強度也降低，或者握把40相對於主體框架12的位置發生偏離。具體而言，進行了如下的精心設計。In consideration of the above, the stroller 10 of this embodiment is carefully designed to prevent the following situation: when the handle 40 is placed in the second position (facing the push position), the stroller 10 in the unfolded state unexpectedly becomes the folded state, or Even if it does not become a folded state, the strength of the main body frame 12 is reduced, or the position of the grip 40 relative to the main body frame 12 is deviated. Specifically, the following careful design was carried out.

即，如圖8所示，狀態維持部件50具有從主體部51突出的框架側卡合突出部55。框架側卡合突出部55從主體部51向寬度方向外側突出。框架側卡合突出部55具有面向由軸部件30劃出的軸線30x的內側面55a、和與內側面55a對置的外側面55b。That is, as shown in FIG. 8, the state maintaining member 50 has a frame-side engagement protrusion 55 protruding from the main body portion 51. The frame-side engagement protrusion 55 protrudes outward in the width direction from the main body 51. The frame-side engagement protrusion 55 has an inner surface 55a facing the axis 30x drawn by the shaft member 30, and an outer surface 55b facing the inner surface 55a.

此外，如圖8所示，握把40具有設置在握把主體41的限制部件65。限制部件65在握把40的U字的兩端部固定於握把主體41。限制部件65隨著握把主體41相對於主體框架12的擺動而相對於主體框架12擺動。In addition, as shown in FIG. 8, the grip 40 has a restricting member 65 provided on the grip main body 41. The restriction member 65 is fixed to the grip main body 41 at both ends of the U-shape of the grip 40. The restricting member 65 swings relative to the main body frame 12 in accordance with the swing of the grip main body 41 relative to the main body frame 12.

限制部件65具有安裝在握把主體41的主體部66與從主體部66向寬度方向內側突出的握把側卡合突出部67。主體部66具有凹部66a，該凹部66a在操作部件60位於非操作位置時收納操作突出部62。握把側卡合突出部67具有第1部分68與第2部分69，第1部分68具有沿以軸線30x為中心的圓的周向延伸的第1面68a，第2部分69與第1部分68連接。The restriction member 65 has a main body portion 66 attached to the grip main body 41 and a grip-side engagement protrusion 67 protruding from the main body portion 66 inward in the width direction. The main body portion 66 has a recessed portion 66a that accommodates the operating protrusion 62 when the operating member 60 is in the non-operating position. The grip-side engagement protrusion 67 has a first portion 68 and a second portion 69. The first portion 68 has a first surface 68a extending in the circumferential direction of a circle centered on the axis 30x, and the second portion 69 and the first portion 68 connections.

根據圖12～圖14可理解，第1部分68以第1面68a與軸線30x之間的距離比框架側卡合突出部55的外側面55b與軸線30x的距離大的方式設置。換言之，第1部分68設置在比框架側卡合突出部55更靠近以軸線30x為中心的圓的徑向外側的位置。此外，如圖14所示，在握把40處於第2位置的情況下，第1部分68以在從框架側卡合突出部55朝向軸線30x的方向觀察與框架側卡合突出部55重疊的方式設置。換言之，在握把40處於第2位置的情況下，第1部分68從自狀態維持部件50的限制位置向解除位置的移動方向中的前方面向框架側卡合突出部55。由此，在握把40處於第2位置的情況下，從狀態維持部件50的限制位置向解除位置的移動被限制部件65限制。另一方面，如圖12所示，在握把40處於第1位置的情況下，第1部分68在從框架側卡合突出部55朝向軸線30x的方向觀察不與框架側卡合突出部55重疊。由此，在握把40處於第1位置的情況下，限制部件65不妨礙狀態維持部件50從限制位置向解除位置移動。換言之，在握把40處於第1位置的情況下，限制部件65允許狀態維持部件50從限制位置向解除位置移動。It can be understood from FIGS. 12 to 14 that the first portion 68 is provided such that the distance between the first surface 68a and the axis 30x is greater than the distance between the outer surface 55b of the frame-side engagement protrusion 55 and the axis 30x. In other words, the first portion 68 is provided at a position closer to the radially outer side of the circle centered on the axis 30x than the frame-side engagement protrusion 55. In addition, as shown in FIG. 14, when the grip 40 is in the second position, the first portion 68 overlaps the frame-side engagement protrusion 55 when viewed from the frame-side engagement protrusion 55 toward the axis 30x. set up. In other words, when the grip 40 is in the second position, the first portion 68 faces the frame side engagement protrusion 55 from the front in the movement direction from the restriction position of the state maintaining member 50 to the release position. Thus, when the grip 40 is in the second position, the movement from the restriction position of the state maintaining member 50 to the release position is restricted by the restriction member 65. On the other hand, as shown in FIG. 12, when the grip 40 is in the first position, the first portion 68 does not overlap the frame-side engagement protrusion 55 when viewed from the frame-side engagement protrusion 55 toward the axis 30x. . Thus, when the grip 40 is in the first position, the restricting member 65 does not prevent the state maintaining member 50 from moving from the restricting position to the releasing position. In other words, when the grip 40 is in the first position, the restriction member 65 allows the state maintaining member 50 to move from the restriction position to the release position.

如圖8所示，第2部分69連接至在握把40從第1位置向第2位置擺動時的限制部件65的旋轉方向Dr上成為第1部分68的後方端部的位置。第2部分69具有徑向面69a，徑向面69a從第1部分68的上述後方端部向以軸線30x為中心的圓的徑向內側延伸。如圖14所示，在握把40處於第2位置的情況下，徑向面69a從上述旋轉方向Dr的後方面向框架側卡合突出部55。As shown in FIG. 8, the second portion 69 is connected to a position that becomes the rear end of the first portion 68 in the rotation direction Dr of the restricting member 65 when the grip 40 swings from the first position to the second position. The second portion 69 has a radial surface 69a, and the radial surface 69a extends from the rear end of the first portion 68 to the radial inner side of a circle centered on the axis 30x. As shown in FIG. 14, when the grip 40 is in the second position, the radial surface 69a engages the protrusion 55 toward the frame side from the rear of the rotation direction Dr.

透過這樣的限制部件65的第1部分68與框架側卡合突出部55，握把40配置於第2位置時的狀態維持部件50向解除位置的移動被限制。具體而言，即使從後方對後輪19施加衝擊等，從而從後腿16向狀態維持部件50施加推起狀態維持部件50的力，也可透過從狀態維持部件50突出的框架側卡合突出部55與握把側卡合突出部67的第1部分68抵接，來防止狀態維持部件50向解除位置的移動。由此，可防止狀態維持部件50與第4連杆L4的卡合被解除。Through the first portion 68 of the restricting member 65 and the frame-side engagement protrusion 55, the movement of the state maintaining member 50 to the release position when the grip 40 is arranged in the second position is restricted. Specifically, even if an impact or the like is applied to the rear wheel 19 from the rear, and a force is applied from the rear leg 16 to the state maintaining member 50 to push up the state maintaining member 50, it can be projected through the frame side protruding from the state maintaining member 50. The portion 55 abuts on the first portion 68 of the grip-side engagement protrusion 67 to prevent the movement of the state maintaining member 50 to the release position. Thereby, it is possible to prevent the engagement between the state maintaining member 50 and the fourth link L4 from being released.

此外，透過限制部件65的第2部分69與框架側卡合突出部55，第2連杆L2相對於後腿16向後方的傾倒被限制。具體而言，即使從後方對後輪19施加衝擊等，從而從後腿16向第2連杆L2施加使第2連杆L2向後方傾倒的力，也可透過從狀態維持部件50突出的框架側卡合突出部55與握把側卡合突出部67的第2部分69抵接，來防止第2連杆L2向後方傾倒。由此，可防止限制卡合突起52從限制卡合凹部29a脫出而解除狀態維持部件50與第4連杆L4的卡合這樣的情況。In addition, through the second portion 69 of the restricting member 65 and the frame-side engagement protrusion 55, the second link L2 is restricted from falling backward with respect to the rear leg 16. Specifically, even if an impact or the like is applied to the rear wheel 19 from the rear, and a force is applied from the rear leg 16 to the second link L2 to cause the second link L2 to fall backward, it can pass through the frame protruding from the state maintaining member 50 The side engagement protrusion 55 abuts on the second portion 69 of the grip side engagement protrusion 67 to prevent the second link L2 from falling backward. Thereby, it is possible to prevent a situation in which the restricting engagement protrusion 52 comes out of the restricting engagement recess 29a and the engagement of the state maintaining member 50 and the fourth link L4 is released.

另外，在圖示的例子中，由於限制部件65相對於主體框架12固定，因此僅透過將握把40配置在第2位置，狀態維持部件50與限制部件65就自動卡合。In addition, in the illustrated example, since the restricting member 65 is fixed to the main body frame 12, only by arranging the grip 40 in the second position, the state maintaining member 50 and the restricting member 65 are automatically engaged.

此外，根據圖13可理解，在圖示的例子中，框架側卡合突出部55以及第1部分68在握把40從第1位置向第2位置移動時，在握把40到達第2位置之前，在從框架側卡合突出部55朝向軸線30x的方向觀察時開始相互重疊。透過這樣設置框架側卡合突出部55以及第1部分68，即使在使握把40從第1位置移動至第2位置的中途（或者在從第2位置移動至第1位置的中途）操作遠程操作裝置43，也能夠降低狀態維持部件50與第4連杆L4的卡合被解除的風險。由此，能夠進一步有效地降低嬰兒車10被意外地折疊的風險。In addition, as can be understood from FIG. 13, in the example shown in the figure, the frame-side engagement protrusion 55 and the first portion 68 move from the first position to the second position of the grip 40 before the grip 40 reaches the second position. When viewed from the frame-side engagement protrusion 55 toward the direction of the axis 30x, they start to overlap with each other. By providing the frame-side engagement protrusion 55 and the first part 68 in this way, the remote control can be operated even when the grip 40 is moved from the first position to the second position (or in the middle of moving from the second position to the first position). The operating device 43 can also reduce the risk that the engagement between the state maintaining member 50 and the fourth link L4 is released. As a result, the risk of accidental folding of the stroller 10 can be further effectively reduced.

且本實施方式的嬰兒車10為了抑制以下情況進行了進一步的精心設計：在握把40配置於第2位置（面向推動位置）時，處於展開狀態的嬰兒車10意外地成為折疊狀態，或者即使不至於成為折疊狀態，主體框架12的強度也降低，或者握把40相對於主體框架12的位置發生偏離。具體而言，進行了如下的精心設計。In addition, the stroller 10 of this embodiment is further elaborately designed to prevent the following situation: when the handle 40 is placed in the second position (facing the push position), the stroller 10 in the unfolded state unexpectedly becomes the folded state, or even if it does not As for the folded state, the strength of the main body frame 12 is also reduced, or the position of the grip 40 relative to the main body frame 12 is deviated. Specifically, the following careful design was carried out.

首先，如圖11所示，握把側第2卡合突部70從握把主體41的軸部41a朝向寬度方向內側伸出。握把側第2卡合突部70相對於軸部41a固定。在圖示的例子中，握把側第2卡合突部70從止動件41c伸出。First, as shown in FIG. 11, the second grip-side engagement protrusion 70 protrudes from the shaft portion 41 a of the grip main body 41 toward the inner side in the width direction. The second grip-side engagement protrusion 70 is fixed to the shaft 41a. In the example shown in the figure, the grip-side second engaging protrusion 70 protrudes from the stopper 41c.

此外，如圖10所示，在主體框架12中的面向處於第2位置的握把40的位置，設置有朝向寬度方向外側突出的框架側第2卡合突部71。根據圖14可理解，框架側第2卡合突部71設置成在握把40處於第2位置的情況下從下方面向握把側第2卡合突部70。在圖示的例子中，框架側第2卡合突部71設置在第1連杆L1的第2位置保持部37的下方。In addition, as shown in FIG. 10, at a position facing the grip 40 in the second position in the main body frame 12, a frame-side second engagement protrusion 71 protruding outward in the width direction is provided. As can be understood from FIG. 14, the frame-side second engaging protrusion 71 is provided to face the grip-side second engaging protrusion 70 from below when the grip 40 is in the second position. In the example shown in the figure, the frame-side second engagement protrusion 71 is provided below the second position holding portion 37 of the first link L1.

透過這樣的握把側第2卡合突部70與連杆側第2卡合突部71，握把40配置於第2位置時的、握把40相對於主體框架12的移動（特別是相對於主體框架12向下方的移動）被限制。即，從後方對後輪19施加衝擊等的結果為，即使意外地解除狀態維持部件50與第4連杆L4的卡合，握把側第2卡合突部70也由框架側第2卡合突部71從下方支承。由此，可防止握把40相對於主體框架12向下方移動。其結果為，能夠防止使用了握把40的嬰兒車10的操作性降低。進而，握把側第2卡合突部70被框架側第2卡合突部71從下方支承，由此可防止樞軸連接於握把40的第2連杆L2相對於後腿16旋轉，且可防止嬰兒車10的意外的折疊、處於展開狀態的主體框架12的強度的降低。Through such a grip-side second engaging protrusion 70 and a link-side second engaging protrusion 71, when the grip 40 is placed in the second position, the grip 40 moves relative to the main body frame 12 (especially relative The downward movement of the main body frame 12) is restricted. That is, as a result of applying an impact to the rear wheel 19 from the rear, even if the engagement between the state maintaining member 50 and the fourth link L4 is unexpectedly released, the second engagement protrusion 70 on the grip side is also engaged by the second frame side. The joint protrusion 71 is supported from below. As a result, the grip 40 can be prevented from moving downward with respect to the main body frame 12. As a result, it is possible to prevent the operability of the stroller 10 using the grip 40 from deteriorating. Furthermore, the grip-side second engaging protrusion 70 is supported from below by the frame-side second engaging protrusion 71, thereby preventing the second link L2 pivotally connected to the grip 40 from rotating relative to the rear leg 16. In addition, accidental folding of the stroller 10 and reduction of the strength of the main frame 12 in the unfolded state can be prevented.

另外，握把側第2卡合突部70及框架側第2卡合突部71設置為在握把40從第1位置向第2位置移動時，在握把40到達第2位置之前，使框架側第2卡合突部71開始從下方面向握把側第2卡合突部70。由此，即使在使握把40從第1位置移動至第2位置的中途（或者在從第2位置移動至第1位置的中途）操作遠程操作裝置43等而使狀態維持部件50與第4連杆L4的卡合被解除，也能夠透過握把側第2卡合突部70被框架側第2卡合突部71支承，降低握把40相對於主體框架12向下方移動的風險。此外，樞軸連接於握把40的第2連杆L2相對於後腿16旋轉的風險降低，從而降低嬰兒車10被意外地折疊的風險、處於展開狀態的主體框架12的強度降低的風險。In addition, the handle-side second engaging protrusion 70 and the frame-side second engaging protrusion 71 are provided so that when the handle 40 moves from the first position to the second position, before the handle 40 reaches the second position, the frame side The second engagement protrusion 71 starts to face the second engagement protrusion 70 on the grip side from below. As a result, even when the grip 40 is moved from the first position to the second position (or during the movement from the second position to the first position), the remote operating device 43 is operated, and the state maintaining member 50 and the fourth position are operated. The engagement of the link L4 is released, and it can also be supported by the frame-side second engagement protrusion 71 through the grip-side second engagement protrusion 70, thereby reducing the risk of the grip 40 moving downward with respect to the main body frame 12. In addition, the risk of the second link L2 pivotally connected to the grip 40 rotating relative to the rear leg 16 is reduced, thereby reducing the risk of accidentally folding the stroller 10 and the risk of reducing the strength of the main frame 12 in the unfolded state.

另外，上述嬰兒車10僅為一例，可進行各種變更。In addition, the above-mentioned stroller 10 is only an example, and various changes can be made.

例如，在上述的例子中，在握把40配置於第2位置時的狀態維持部件50從限制位置向解除位置的移動透過框架側卡合突出部55與握把側卡合突出部67抵接而被限制，但不限於此。狀態維持部件50的上述移動例如也可以透過利用磁力吸附限制部件65與狀態維持部件50來進行限制。在該情況下，如圖15所示，在狀態維持部件50以及限制部件65中，以在握把40配置於第2位置時從寬度方向（沿軸線30x的方向）觀察時磁鐵155、168相互重疊的方式分別設置有磁鐵155、168即可。For example, in the above-mentioned example, the movement of the state maintaining member 50 from the restriction position to the release position when the grip 40 is arranged in the second position is caused by abutting the frame-side engaging protrusion 55 and the grip-side engaging protrusion 67. Is restricted, but not limited to this. The above-mentioned movement of the state maintaining member 50 may be restricted by, for example, attracting the restricting member 65 and the state maintaining member 50 by magnetic force. In this case, as shown in FIG. 15, in the state maintaining member 50 and the restricting member 65, the magnets 155 and 168 overlap each other when viewed from the width direction (the direction along the axis 30x) when the grip 40 is arranged in the second position. The magnets 155 and 168 can be provided in the same manner.

此外，在握把40配置於第2位置時的握把40相對於主體框架12向下方的移動透過握把側第2卡合突部70由連杆側第2卡合突部71從下方支承而被限制，但不限於此。握把40的上述移動例如也可以透過利用磁力吸附握把40與主體框架12來進行限制。在該情況下，如圖15所示，在握把40（圖示的例子中為止動件41c）以及主體框架12（圖示的例子中為扶手21）中，以在握把40配置於第2位置時從寬度方向（沿軸線30x的方向）觀察時磁鐵170、171相互重疊的方式分別設置有磁鐵170、171即可。在圖15所示的例子中，磁鐵170、171構成限制握把40的上述移動的限制部。In addition, the downward movement of the grip 40 with respect to the main body frame 12 when the grip 40 is arranged in the second position is supported by the second engagement protrusion 70 on the grip side by the second engagement protrusion 71 on the link side. Is restricted, but not limited to this. The aforementioned movement of the grip 40 may be restricted by, for example, attracting the grip 40 and the main body frame 12 by magnetic force. In this case, as shown in FIG. 15, in the grip 40 (stopper 41c in the example shown) and the main body frame 12 (the armrest 21 in the example shown), the grip 40 is arranged at the second position When viewed from the width direction (the direction along the axis 30x), the magnets 170 and 171 may be provided so that the magnets 170 and 171 overlap each other. In the example shown in FIG. 15, the magnets 170 and 171 constitute a restricting portion that restricts the aforementioned movement of the grip 40.

在以上說明的實施方式中，嬰兒車10是可從展開狀態向折疊狀態折疊的嬰兒車，具備可從展開狀態向折疊狀態變形的主體框架12、可在第1位置與第2位置之間擺動地連接於主體框架12的握把40。主體框架12具有可在限制位置與解除位置之間移動的狀態維持部件50，所述限制位置是使嬰兒車10的折疊動作受到限制的位置，所述解除位置是可進行嬰兒車10的折疊動作的位置。此外，握把40具有：握把主體41，連接於主體框架12；限制部件65，在位於第2位置時，限制狀態維持部件50從限制位置向解除位置移動。In the embodiment described above, the stroller 10 is a stroller that can be folded from an unfolded state to a folded state, and includes a main body frame 12 that can be deformed from an unfolded state to a folded state, and can swing between the first position and the second position. The ground is connected to the grip 40 of the main frame 12. The main body frame 12 has a state maintaining member 50 that can be moved between a restricted position where the folding operation of the stroller 10 is restricted, and a release position where the folding operation of the stroller 10 can be performed s position. In addition, the grip 40 has a grip main body 41 connected to the main body frame 12, and a restricting member 65 that moves the restricted state maintaining member 50 from the restricting position to the releasing position when it is located in the second position.

根據這樣的嬰兒車10，在握把40處於第2位置的情況下，可防止狀態維持部件50從限制位置向解除位置移動。因此，在握把40位於第2位置的情況下，即使對主體框架12施加強烈衝擊等而對狀態維持部件50賦予從限制位置朝向解除位置的力，也可防止狀態維持部件50向解除位置移動。因此，可降低嬰兒車10被意外地折疊的風險。According to such a stroller 10, when the grip 40 is in the second position, the state maintaining member 50 can be prevented from moving from the restriction position to the release position. Therefore, when the grip 40 is in the second position, even if a strong impact or the like is applied to the main body frame 12 and a force is applied to the state maintaining member 50 from the restricted position to the releasing position, the state maintaining member 50 can be prevented from moving to the releasing position. Therefore, the risk of accidental folding of the stroller 10 can be reduced.

另外，在以上說明的實施方式中，限制部件65相對於握把主體41固定。由此，只要將握把40配置在第2位置，就能夠自動地限制狀態維持部件50從限制位置向解除位置的移動。In addition, in the embodiment described above, the restricting member 65 is fixed to the grip main body 41. Thereby, as long as the grip 40 is arranged in the second position, the movement of the state maintaining member 50 from the restriction position to the release position can be automatically restricted.

此外，在以上說明的實施方式中，狀態維持部件50具有主體部51與從主體部51突出的框架側卡合突出部55。此外，限制部件65具有握把側卡合突出部67，在握把40位於第2位置時，從自限制位置朝向解除位置的方向上的前方面向框架側卡合突出部55。透過這樣的框架側卡合突出部55與握把側卡合突出部67，能夠限制握把40位於第2位置時的狀態維持部件50的上述移動。In addition, in the embodiment described above, the state maintaining member 50 has the main body 51 and the frame-side engagement protrusion 55 protruding from the main body 51. In addition, the restricting member 65 has the grip-side engaging protrusion 67, and when the grip 40 is in the second position, it faces the frame-side engaging protrusion 55 from the front in the direction from the restricting position to the releasing position. With such a frame-side engaging protrusion 55 and a grip-side engaging protrusion 67, the above-mentioned movement of the state maintaining member 50 when the grip 40 is in the second position can be restricted.

此外，在以上說明的實施方式中，握把側卡合突出部67具有在握把40位於第2位置時，從自第1位置朝向第2位置的方向Dr上的後方面向框架側卡合突出部55的部分69。由此，在對主體框架12施加強烈衝擊等的情況下，能夠從上述方向Dr的後方支承主體框架12。由此，能夠降低主體框架12被意外地折疊的風險。In addition, in the above-described embodiment, the grip-side engaging protrusion 67 has a frame-side engaging protrusion from the rear in the direction Dr from the first position to the second position when the grip 40 is in the second position. Part 69 of 55. Thereby, when a strong impact or the like is applied to the main body frame 12, the main body frame 12 can be supported from the rear in the above-mentioned direction Dr. Thereby, the risk of accidental folding of the main body frame 12 can be reduced.

此外，在以上說明的實施方式中，主體框架12具有：前腿14以及後腿16、與前腿14以及後腿16可轉動地連接的第1連杆L1、與第1連杆L1可轉動地連接且在展開狀態下被後腿16支承的第2連杆L2。並且，狀態維持部件50被第二連杆L2支承，握把40與第二連杆L2可擺動地連接。在這樣的嬰兒車10的情況下，若使嬰兒車10以後腿16側成為行進方向的前方的方式行走，則有時會對後腿16施加強烈衝擊從而對第2連杆L2的狀態維持部件50賦予朝向解除位置的力。然而，根據本實施方式的嬰兒車10，如果使握把40處於第2位置，則限制部件65限制狀態維持部件50從限制位置向解除位置的移動，因此即使對狀態維持部件50賦予朝向解除位置的力，也可降低狀態維持部件50向解除位置移動的風險。In addition, in the embodiment described above, the main body frame 12 has: the front leg 14 and the rear leg 16, the first link L1 rotatably connected to the front leg 14 and the rear leg 16, and the first link L1 is rotatable The second link L2 connected to the ground and supported by the rear leg 16 in the expanded state. In addition, the state maintaining member 50 is supported by the second link L2, and the grip 40 and the second link L2 are swingably connected. In the case of such a stroller 10, if the stroller 10 is walked with the rear leg 16 side facing forward in the direction of travel, a strong impact may be applied to the rear leg 16 and the state maintaining member of the second link L2 may be applied. 50 gives a force toward the release position. However, according to the stroller 10 of the present embodiment, if the grip 40 is in the second position, the restricting member 65 restricts the movement of the state maintaining member 50 from the restricting position to the releasing position. Therefore, even if the state maintaining member 50 is given the direction releasing position This force can also reduce the risk of the state maintaining member 50 moving to the release position.

此外，在以上說明的實施方式中，握把40具有從握把主體41突出的握把側第2卡合突部70。此外，主體框架12具有從主體框架12中的第2連杆L2以外的部分突出的框架側第2卡合突部71。並且，框架側第2卡合突部71在握把40位於第2位置時從下方面向握把側第2卡合突部70。透過這樣的握把側第2卡合突部70與連杆側第2卡合突部71，握把40配置於第2位置時的、握把40相對於主體框架12的移動（特別是相對於主體框架12向下方的移動）被限制。即，即使意外地解除狀態維持部件50與第4連杆L4的卡合，透過由框架側第2卡合突部71從下方支承握把側第2卡合突部70，也可防止握把40相對於主體框架12向下方移動。由此，能夠降低由於握把40相對於主體框架12發生位置偏離而使得使用了握把40的嬰兒車10的操作性降低這樣的風險。進而，透過由連杆側第2卡合突部71支承握把40，可防止樞軸連接於握把40的第2連杆L2相對於後腿16旋轉，從而可降低嬰兒車10的意外折疊的風險或處於展開狀態的主體框架12的強度降低的風險。In addition, in the embodiment described above, the grip 40 has the grip-side second engagement protrusion 70 protruding from the grip main body 41. In addition, the main body frame 12 has a second frame-side engagement protrusion 71 protruding from a portion other than the second link L2 in the main body frame 12. In addition, the frame-side second engagement protrusion 71 faces the grip-side second engagement protrusion 70 from below when the grip 40 is in the second position. Through such a grip-side second engaging protrusion 70 and a link-side second engaging protrusion 71, when the grip 40 is placed in the second position, the grip 40 moves relative to the main body frame 12 (especially relative The downward movement of the main body frame 12) is restricted. In other words, even if the engagement between the state maintaining member 50 and the fourth link L4 is unexpectedly released, the second engagement protrusion 71 on the frame side supports the second engagement protrusion 70 on the grip side from below to prevent the grip. 40 moves downward with respect to the main body frame 12. As a result, it is possible to reduce the risk that the operability of the stroller 10 using the grip 40 will be reduced due to the positional deviation of the grip 40 with respect to the main body frame 12. Furthermore, by supporting the grip 40 by the second engagement protrusion 71 on the link side, the second link L2 pivotally connected to the grip 40 can be prevented from rotating relative to the rear leg 16, thereby reducing accidental folding of the stroller 10 The risk of reducing the strength of the main frame 12 in the unfolded state.

此外，在以上說明的實施方式中，嬰兒車10是可從展開狀態向折疊狀態折疊的嬰兒車，具備可從展開狀態向折疊狀態變形的主體框架12、可在第1位置與第2位置之間擺動地連接於主體框架12的握把40。握把40具有連接於主體框架12的握把主體41與從握把主體41突出的握把側卡合突部70。此外，主體框架12具有在握把40位於第2位置時從下方面向握把側卡合突部70的框架側卡合突部71。In addition, in the embodiment described above, the stroller 10 is a stroller that can be folded from an unfolded state to a folded state, and includes a main body frame 12 that can be deformed from an unfolded state to a folded state, and can be positioned between the first position and the second position The grip 40 is swingably connected to the main body frame 12. The grip 40 has a grip main body 41 connected to the main body frame 12 and a grip-side engagement protrusion 70 protruding from the grip main body 41. In addition, the main body frame 12 has a frame-side engagement protrusion 71 that faces the grip-side engagement protrusion 70 from below when the grip 40 is in the second position.

根據這樣的嬰兒車10，透過握把側卡合突部70與連杆側卡合突部71，握把40配置在第2位置時的、握把40相對於主體框架12的移動（特別是相對於主體框架12向下方的移動）被限制。即，即使意外地解除用於將主體框架12維持在展開狀態的主體框架12的構成元件之間的卡合，也可防止握把40相對於主體框架12向下方移動。由此，能夠降低由於握把40相對於主體框架12發生位置偏離而使得使用了握把40的嬰兒車10的操作性降低這樣的風險。進而，透過由連杆側卡合突部71支承握把40，即使意外解除上述構成元件之間的卡合，也可降低處於展開狀態的主體框架12意外地變形為折疊狀態的風險、處於展開狀態的主體框架12的強度降低的風險。另外，僅透過將握把40配置在第2位置就可自動地限制握把40相對於主體框架12的移動。According to such a stroller 10, when the grip 40 is placed in the second position through the grip-side engaging protrusion 70 and the link-side engaging protrusion 71, the movement of the grip 40 relative to the main body frame 12 (especially The downward movement with respect to the main body frame 12) is restricted. That is, even if the engagement between the constituent elements of the main body frame 12 for maintaining the main body frame 12 in the expanded state is accidentally released, the grip 40 can be prevented from moving downward with respect to the main body frame 12. As a result, it is possible to reduce the risk that the operability of the stroller 10 using the grip 40 will be reduced due to the positional deviation of the grip 40 with respect to the main body frame 12. Furthermore, by supporting the grip 40 by the link-side engagement protrusion 71, even if the engagement between the above-mentioned constituent elements is accidentally released, the risk that the main body frame 12 in the unfolded state will be accidentally deformed into the folded state and unfolded can be reduced. There is a risk that the strength of the main frame 12 in the state will decrease. In addition, only by arranging the grip 40 in the second position, the movement of the grip 40 with respect to the main body frame 12 can be automatically restricted.

另外，以上說明了針對上述實施方式的幾種變形例，當然也可將多個變形例適當組合進行應用。In addition, several modified examples of the above-mentioned embodiment have been described above, and of course, a plurality of modified examples may be appropriately combined and applied.
