In addition, as shown in FIG. 1 and FIG. 2 , the baby carriage 10 and the baby carriage body 15 shown in the figure have a substantially symmetrical structure centered on a plane located at the center in the lateral direction and along the front-rear direction and the up-down direction as a whole.

In this manual, the terms "front", "rear", "upper", "lower", "front-to-back direction", and "up-and-down direction" for the stroller and its constituent elements mean the following "Front", "Rear", "Up", "Down", "Front-Rear Direction", and "Up-Down Direction" based on the infants and toddlers riding in the unfolded stroller and its components. More specifically, the "front-back direction" is the direction connecting the lower left and upper right of the paper in FIGS. 1 and 2 , which is equivalent to the left-right direction in the paper of FIG. 3 . Moreover, unless otherwise specified, "before" means riding The side facing the infant, the lower left side of the paper in Figures 1 and 2 and the left side of the paper in Figure 3 are the front side. On the other hand, the "up and down direction" is a direction perpendicular to the running surface of the stroller. Therefore, when the running surface is a horizontal plane, the "up and down direction" means the vertical direction. In addition, the "horizontal direction" is a width direction, and is a direction perpendicular to any of the "front-back direction" and the "up-down direction". The "inside" or "inside" in the width direction (horizontal direction) indicates the side close to the center of the stroller in the width direction, and the "outside" or "outside" in the width direction (horizontal direction) indicates the same as the side of the stroller in the width direction. Center split sides. Furthermore, the "rear side" used in connection with the seat support unit and the like means the side opposite to the side facing the infant riding in the stroller. Therefore, the "rear side" generally refers to the rear side or the lower side.

First, the stroller main body 15 will be described. The baby carriage body 15 shown in the figure is foldable. As mentioned above, the stroller body 15 includes the body frame 20 and the seat support unit 40, but first of all, the body frame 20 and the seat support unit 40 are not clearly distinguished, and each component that constitutes the stroller body 15 as a foldable illustrate.

The stroller body 15 further has a first link L1, a second link L2, a third link L3, and a fourth link L4 arranged left and right. The front legs 21, the rear legs 23, and the first to fourth links L1 to L4 function as links that make the stroller body 15 foldable and expandable.

As shown in FIG. 2 , the front legs 21 hold the front wheels 22 rotatably at their lower end portions. The front wheels 22 constitute casters, and are rotatable and swivel. The rear leg 23 keeps the rear wheel 24 rotatable at its lower end portion. change. The front leg 21 and the rear leg 23 can be formed using metal pipes such as aluminum alloy, for example.

As shown in FIG. 2 , the upper end portion of the front leg 21 is rotatably (swingably) connected to the front portion of the first link L1 disposed on the corresponding side (left or right). The upper end portion of the rear leg 23 is rotatably (swingably) connected to the front portion of the first link L1 disposed on the corresponding side (left or right). The first link L1 can be constituted by, for example, a resin molded product. In the illustrated example, the first link L1 can function as a handrail.

As can be understood from FIG. 3 , the second link L2 is rotatably (swingably) connected to the rear end portion of the first link L1 disposed on the corresponding side (left or right). In the illustrated example, the second link L2 constitutes a part of the handle 30 . The handle 30 has a U-shape as a whole. The handle 30 has a pair of shaft parts 31 and a connection part 32 connecting the pair of shaft parts 31 . Each shaft portion 31 constitutes the second link L2. The connecting portion 32 connects the upper end portions of the pair of shaft portions 31 . The handle 30 can be comprised using metal pipes, such as aluminum alloy, for example.

As shown in FIGS. 2 and 3 , the third link L3 is rotatably connected to the rear leg 23 disposed on the corresponding side (left or right). The 3rd link L3 can be comprised using metal pipes, such as aluminum alloy, or a resin molding, for example. In the illustrated example, the lower end portion of the third link L3 is rotatably connected to the middle portion of the rear leg 23 .

As shown in FIGS. 2 and 3 , the fourth link L4 is rotatably connected to the front leg 21 disposed on the corresponding side (left or right). In the illustrated example, the fourth link L4 is rotatably connected to the middle part of the front leg 21 at its front end. As will be described later in detail, the fourth link L4 constitutes the seat support unit. part.

In the example shown in the figure, the second link L2, the third link L3, and the fourth link L4 arranged on the same side (left or right) in the width direction can rotate mutually by using the same shaft member 35 (refer to FIG. 3 ). Connect dynamically. The shaft member 35 passes through the second link L2, the third link L3, and the fourth link L4. With this configuration, the second link L2 , the third link L3 , and the fourth link L4 can rotate around each other around the axis that coincides with the central axis of the shaft member 35 .

As shown in FIG. 2 , the stroller body 15 includes a front connecting member 26 connecting the pair of front legs 21 and a rear connecting member 27 connecting the pair of rear legs 23 as components extending in the lateral direction. The front connecting member 26 functions as a footrest. The front connection material 26 and the rear connection material 27 can be comprised using metal pipes, such as aluminum alloy, or a resin molding, for example. Also, a flexible guide member 28 is detachably provided between the pair of first links L1.

The stroller main body 15 having the above configuration can be folded by rotating the respective constituent members relative to each other. Specifically, the third link L3 is rotated clockwise in FIG. . Accompanying this operation, the first link L1 and the fourth link L4 rotate clockwise in FIG. 3 with respect to the second link L2. Through such an operation, in a side view, the handle 30 and the front leg 21 maintain a substantially parallel relationship on one side, and approach each other on the other side, and the position of the handle 30 is lowered. As above, the stroller body 15 can be folded. In the folded state, the baby carriage 10 can be miniaturized in size along the front-rear direction and the up-down direction. On the other hand, to unfold the stroller body 15 from the folded state, it is only necessary to perform the reverse steps of the above-mentioned folding operation.

In the configuration of the baby carriage body 15 described above, the side frame element 50 is included in the seat support unit 40 , and other configurations are included in the body frame 20 .

Next, the seat support unit 40 will be described in detail. As shown in FIGS. 2 to 3 , the seat support unit 40 has a seat support 42 and a back support 44 . The seat support body 42 faces the buttocks of the baby sitting on the stroller 10 . The back support body 44 faces the back of the baby sitting on the stroller 10 .

First, the seat support body 42 of the seat support unit 40 will be described with reference to FIGS. 4 to 7 . In addition, in FIGS. 1 to 4, part or all of the seat support unit 40 shown in FIGS. 4 to 7 may be omitted.

4 and 5 are respectively a perspective view and a top view showing the seat support unit 40, and FIG. 6 is a cross-sectional view along line VI-VI of FIG. 5 . As shown in FIGS. 4 to 6 , the seat support body 42 includes a pair of side frame elements 50 , a connecting member 60 and a seat-shaped member 65 as main constituent elements. In addition, the perspective view of FIG. 7 shows the seat support unit 40 in a state where the seat-shaped member 65 is removed from the same direction as FIG. 4 .

As shown in FIG. 2 , the side frame elements 50 constitute the fourth link L4 as described above. The pair of side frame elements 50 are arranged separately in the width direction. Each side frame element 50 extends in the front-rear direction. The side frame element 50 is rotatably connected to the middle part of the front leg 21 at its front end. Also, the side frame element 50 is connected to the lower end portion of the second link L2 and the third link at its rear end portion. The upper end portion of L3 is rotatably connected.

As shown in FIG. 4 , the side frame element 50 has: a side frame material 51 extending in the front-rear direction, a front-end member 52 fixed to the front end portion of the side frame material 51 , and a rear-end member fixed to the rear end portion of the side frame material 51 53. The side frame material 51 can be comprised using metal pipes, such as aluminum alloy, for example. The front-end member 52 and the rear-end member 53 can be comprised using resin molding, for example. As clearly shown in FIG. 4 , a bearing hole 52 a through which a shaft (not shown) for rotatably connecting the side frame element 50 and the front leg 21 passes is provided in the front end member 52 . Moreover, the through-hole 52b through which the connection member 60 passes is provided in the front-end|tip member 52. As shown in FIG. A bearing hole (not shown) through which the shaft member 35 passes is formed in the rear end member 53 .

Next, the connecting member 60 is erected on the pair of side frame elements 50 . The connecting member 60 is stretched between the pair of side frame elements 50, and supports the seat 70 and the infant from below. The connecting member 60 is preferably flexible, and further may be elastic. According to such a coupling member 60, the baby can be supported softly, and the riding comfort of the stroller 10 can be improved.

As shown in FIG. 5 , the connecting member 60 is an elongated member extending in the width direction. Also, the width W in the front-rear direction of the connecting member 60 becomes very short relative to the length L in the front-rear direction of the side frame elements 50 . In addition, in the illustrated example, the connection member 60 is formed as a belt-shaped member. However, it is not limited to this example, and the connecting member 60 may be configured as a member having a very small width W, such as what is called a string. As the connecting member 60 , a tape or string made by sewing cloth, a belt or rope member made of natural leather or synthetic leather, a resin belt or rope member, or the like can be used.

The plurality of connection members 60 can be separated from each other in the front-rear direction and erected on the pair of side frame elements 50 . As clearly shown in FIG. 5 , in the seat support unit 40 shown in the figure, the three connecting members 60 are separated from each other in the front-rear direction and erected on a pair of side frame elements 50 . However, it is not limited to the illustrated example, and two connecting members 60 may be installed between a pair of side frame elements 50, and four or more connecting members 60 may be installed. In the case of using a plurality of connecting members 60 , the physical characteristics and configuration can be changed according to the arrangement of each connecting member 60 . For example, the strength of the connecting member 60 located at the rearmost in the front-rear direction can be made greater than the strength of the other connecting members 60 . The width W of the connecting member 60 located at the rearmost in the front-rear direction can be made wider than the width of the other connecting members 60 . In addition, the elongation rate of the connecting member 60 located at the forefront in the front-rear direction can be made larger than the elongation rate of the other connecting members 60 .

In addition, the ratio of the length L of the connecting member 60 arranged (occupied) in the front-back direction to the length L of the side frame elements 50 in the front-back direction may be set to 50% or less, and may further be set to 30% or less. "The length in which the connection member 60 of the front-back direction is arrange|positioned" is the total of the width W along the front-back direction of the several connection member 60 when the several connection member 60 is provided. In the case where the ratio is small, it is not only better in terms of manufacturing cost but also better in terms of sanitation due to the reduction of materials used. Since the connecting member 60 should be maintained in a tight state, it is assumed that it cannot be detached from the side frame elements 50 . The cleaning and cleaning of the connecting member 60 which cannot be removed is time-consuming and laborious and difficult to carry out. Therefore, it is preferable to shorten the length of the connecting member 60 arranged in the front-rear direction as much as possible.

Based on this point, it is preferable that the plurality of connecting members 60 are separated from each other in the front-rear direction and are mounted on the pair of side frame elements 50 . According to this specific example, by distributing a plurality of The connecting member 60 can efficiently and stably support the infant on the seat 70 . That is, the amount of the connecting member 60 can be reduced while stably supporting the infant. Therefore, the hygienic aspect of the stroller can be further improved.

In other words, as shown in FIG. 1 , the stroller 10 has a seat belt 11 for fixing the infant to the seat 70 . The seat safety belt 11 has: the crotch belt 11A that passes the crotch of the infant, the waist belt 11B that passes the infant's waist and can be disassembled with the crotch belt 11A, and the infant's shoulder that can be attached to the crotch belt 11A. Disassembly shoulder strap 11C. As clearly shown in FIGS. 4 and 7 , in the seat support body 42 shown in the figure, the crotch belt 11A is attached to one connecting member 60 . Specifically, a cylindrical portion is formed at the base end portion of the crotch belt 11A by, for example, sewing, and the connection member 60 passes through the cylindrical portion of the crotch belt 11A.

From the standpoint of effective functioning of the seat belt 11, the crotch belt 11A preferably extends from a position in the seat that is slightly forward of the center in the front-rear direction. In the illustrated example, the second connecting member 60B located in the middle in the front-rear direction is provided at a position slightly shifted forward from the center in the front-rear direction in the seat portion. As a result, in the illustrated example, the crotch belt 11A is attached to connecting members other than the first connecting member 60A located at the front in the front-rear direction and the third connecting member 60C located at the rearmost in the front-rear direction. According to such an example, the crotch belt 11A can be held stably by the connection member 60, and the seat belt 11 can be made to function effectively.

As shown in FIG. 5 , the seat support body 42 has the first connecting member 60A positioned at the front most in front of the second connecting member 60B on which the crotch belt 11A is attached. The legs of the infant on the seat 70 can be stably supported by the frontmost first connecting member 60A. especially root According to the flexible first connecting member 60A, the legs can be gently supported, and the riding comfort of the stroller 10 can be improved.

Moreover, as shown in FIG. 5, the seat support body 42 has the 3rd connecting member 60C which is located in the rearmost behind rather than the 2nd connecting member 60B to which the crotch belt 11A was attached in the front-rear direction. The seat surface of a general stroller mainly bears the weight of the infant at the position behind the position where the crotch belt extends. Therefore, an infant can be stably supported by the third connecting member 60C. In particular, the high-strength third connecting member 60C can enhance the stability of supporting the infant and improve the riding comfort of the stroller 10 .

As shown in FIG. 6 , the connecting member 60 is attached to the side frame element 50 on the corresponding side at both ends thereof. Each connecting member 60 extends sequentially above, outside and below the side frame element 50 on the corresponding side at the end portion, and is installed on the inside surface of the side frame element 50 in the width direction. In other words, one end of the connecting member 60 is attached to the inner surface in the width direction of the side frame element 50 (side frame material 51 ), and secondly, connected to the upper, lower, and lower side surfaces and side surfaces of the side frame element 50 (side frame material 51 ). The outer surface of the square frame element 50 (side frame material 51 ) in the width direction and the upper surface of the side frame element 50 (side frame material 51 ) are sequentially contacted, and then further extended inward in the width direction. According to this specific example, the connection member 60 can be attached to the side frame element 50 more firmly. In addition, since the length of the connecting member 60 can be ensured to be long, the infant can be gently supported, and impacts from, for example, the running surface of the stroller 10 can be efficiently absorbed. Furthermore, since the connecting member 60 is installed from the inner side of the side frame element 50 in the width direction, the installation location is not conspicuous, and the appearance of the stroller 10 can be improved.

Moreover, in the example shown in FIG. 6, the connection member 60 is nondetachably fixed to the side frame element 50 by the fixture 63, such as a rivet. As shown in FIG. 5 , the second connecting member 60B and the third connecting member 60C are attached to the side frame member 51 so as to surround the side frame member 51 of the side frame element 50 . That is, the second connecting member 60B and the third connecting member 60C are attached to the side where the end portions of the second connecting member 60B and the third connecting member 60C extend sequentially on the side frame member 51 of the side frame element 50 on the corresponding side, on the outside in the width direction, and on the lower side. The inner surface of the frame material 51 in the width direction.

As shown in FIGS. 5 and 7 , the first coupling member 60A is attached to the front end member 52 . However, the side frame member 51 exists in the front-end member 52 at the position where the 1st connection member 60A is attached. In addition, a through-hole 52 b is provided at a position below the side frame member 51 in the front end member 52 . 60 A of 1st connection members extend from the width direction outer side of the side frame element 50 toward the width direction inner side through the through-hole 52b. By using the through-hole 52b, 60 A of 1st coupling members can be attached stably to the front-end member 52 which has a complicated shape.

Next, the sheet-like member 65 will be described. The seat-shaped member 65 is a resin-made member formed in the shape of a seat or a plate. As shown in FIGS. 4 to 6 , the seat-shaped member 65 is supported by the connection member 60 . Furthermore, as shown in FIG. 8 , the seat 70 is disposed on the seat-shaped member 65 and is supported from below by the seat-shaped member 65 . The seat-shaped member 65 made of resin preferably has a certain degree of flexibility. By adjusting the resin material, thickness, etc., flexibility can be imparted to the seat-shaped member 65 . As an example, the thickness of the seat-shaped member 65 may be 0.5 mm to 2 mm, and may further be 0.8 mm to 1.5 mm. Examples of the resin material used for the seat-shaped member 65 include polypropylene, polycarbonate, and polyethylene terephthalate.

Thus, according to the seat support body 42 provided with the seat-shaped member 65 made of resin supported by the connecting member 60 , the connecting member 60 supports the infant on the seat 70 over a wide area via the seat-shaped member 65 . Therefore, the infant is stably supported with a more uniform force by the seat-like member 65 and the connecting member 60 having a certain degree of flexibility. Moreover, since the connecting member 60 supports the infant through the seat-shaped member 65, the number of connecting members 60 and the width W in the front-back direction can be reduced, and the amount of connecting members 60 can be reduced. In addition, the seat-shaped member 65 made of resin is more excellent in antifouling property than cloth etc., and can be fully washed and cleaned without being attached to the stroller 10 . For example, the seat-shaped member 65 made of resin can be easily decontaminated by dry wiping or wet wiping. That is, by being installed on the seat-shaped member 65, it is possible to stably support infants and toddlers and improve ride comfort, and further improve the hygienic aspect of the stroller.

As shown in FIG. 5 , the length of the seat-shaped member 65 in the front-rear direction is substantially the same as the length of the side frame elements 50 in the front-rear direction. Likewise, the length in the width direction of the seat-shaped member 65 is substantially the same as the distance in the width direction between the widthwise outer surfaces of the opposing side frame elements 50 . That is, the seat-shaped member 65 shown in the figure extends over substantially the entire area of the seat support body 42 in plan view.

Preferably, the pair of side frame elements 50 are positioned so as to at least partially overlap the seat-shaped member 65 in plan view shown in FIG. 5 . According to this configuration, the seat-shaped member 65 is supported from below by the pair of side frame elements 50 . Therefore, the width direction outer part of the seat-shaped member 65 can be restrained from being bent so as to hang down. Thereby, an infant can be supported more stably via the seat-shaped member 65 . Moreover, since the supporting state realized by the seat-shaped member 65 is stable, the number of connecting members 60 and the width W in the front-back direction can be reduced, and the area of the connecting member 60 can be reduced.

In the illustrated example, the seat-shaped member 65 is provided with a hole 65a through which the connecting member 60 passes. The seat-shaped member 65 is held by the connecting member 60 by passing the connecting member 60 through the hole 65 a of the seat-shaped member 65 . According to such a holding method, the seat-shaped member 65 can be relatively moved slightly with respect to the coupling member 60 . With such a play, the impact from the road surface can be absorbed, and the riding comfort of the stroller 10 can be improved.

In particular, as shown in FIGS. 5 and 6 , the seat-like member 65 is provided with a hole 65a through which a connecting member 60 passes. In the illustrated example, the three connecting members 60 are arranged separately in the front-rear direction. Therefore, four holes are provided for each connecting member 60 , and a total of 12 holes 65 a are provided in the seat-shaped member 65 . Each connecting member 60 supports the seat-shaped member 65 from below at both end portions and the central portion in the longitudinal direction thereof. According to this structure, the seat-shaped member 65 is supported from below by the connection member 60, and it can suppress that it hangs down at the outer part in the width direction, and is dented downward at the center part in the width direction. Thereby, the coupling member 60 can more stably support the infant via the seat-like member 65 . Moreover, since the supporting state realized by the seat-shaped member 65 is stable, the number of connecting members 60 and the width W in the front-back direction can be reduced, and the area of the connecting member 60 can be reduced.

The seat side portion 73 may be configured to have cushioning properties similarly to the seat seat portion 71 and the seat back portion 72 . Also, the seat side portion 73 may be made of cloth or the like without cushioning. In addition, illustration of the seat side part 73 is abbreviate|omitted in FIG.8 and FIG.10.

As shown in FIG. 1 , the seat side portion 73 is detachably installed on the body frame 20 of the stroller body 15 . According to this specific example, the seat 70 can be stably held by the body frame 20 and the seat support unit 40 .

As a specific structure, as shown in FIG. 9 , each seat side portion 73 has a third mounting mechanism 75c and a fourth mounting mechanism 75d at a side edge portion on a side separated from the seat back 72 . The third mounting mechanism 75 c is configured, for example, in the same manner as the first mounting mechanism 75 a and the second mounting mechanism 75 b described above, and is mounted on the main body frame 20 . The 4th attachment mechanism 75d has a structure different from the 3rd attachment mechanism 75c, and is attached to the main body frame 20. As shown in FIG. The fourth mounting mechanism 75d can be configured as a fastener such as a button that can be fixed to a fastener mounted on the main body frame 20, for example. The seat side portion 73 can more stably install the seat 70 to the main body frame 20 by having different types of mounting mechanisms 75c and 75d. In addition, in the illustrated example, the seat side portion 73 is detachable from the second link L2 of the main body frame 20 .

In other words, as shown in FIGS. 10 and 3 , etc., the stroller 10 (the stroller body 15 ) further includes a reclining member 37 . The reclining member 37 is connected to the body frame 20 and supports the back support body 44 of the seat support unit 40 from the back side. The reclining member 37 supports the back support body 44 from the back side by being connected to the body frame 20 and positioned on the back side side of the back support body 44 .

As clearly shown in FIG. 10 , the reclining member 37 is mounted on a pair of portions of the handle 30 on both sides of the seat support unit 40 (back support 44 ) in the body frame 20 . The length of the tilting member 37 between a pair of sections becomes variable. The portion of the handle 30 to which the reclining member 37 is mounted is located below the center of the full length of the handle 30 viewed from the side, and above the seat support 42 . As shown in FIG. 3 , by changing the length of the reclining member 37 , the inclination angle of the back support 44 relative to the seat support 42 can be changed. That is, the back support body 44 can be reclined.

In the illustrated example, the reclining member 37 is attached to the second link L2 at both ends thereof. As a specific configuration, the reclining member 37 has a first reclining member 37A, a second reclining member 37B, and an adjuster 37C, which are elongated in the shape of a rope or a belt. One end of the first reclining member 37A is fixed to a second link L2. The first reclining member 37A extends from a second link L2. The second reclining member 37B is fixed to the other second link L2 at one end thereof. The second reclining member 37B extends from the other second link L2. The adjuster 37C can be fixed to any position of the first reclining member 37A and the second reclining member 37B like a clip. Alternatively, the adjuster 37C may be fixed to the other end of the first reclining member 37A, or may be further fixed to an arbitrary position of the second reclining member 37B.

The reclining angle of the back support 44 is determined based on the total length of the length from the end of the first reclining member 37A to the adjuster 37C and the length from the end of the second reclining member 37B to the adjuster 37C. If the total length becomes longer, the back support body 44 will be in a receding (lying down) state as shown by a two-dot chain line in FIG. 3 . Here, in the state shown by the chain line of two dots in FIG. 3, the length of the reclining member 37 between a pair of 2nd link L2 is set to the longest length. That is, the position of the chain line of two dots in FIG. 3 becomes the most receding position of the back support body 44 .

In addition, the back support body 44 can be pushed up from the position shown by the chain line of two dots to stand it up. For this reason, in the illustrated example, the longest length of the reclining member 37 between the pair of second links L2 is such that the reclining member 37 cannot pass over the back support body 44 pulled up by pushing or pressing with hands. length. Thereby, the reclining member 37 does not unintentionally protrude toward the front of the back support body 44 . Therefore, it is possible to effectively prevent the back support body 44 from tilting backward without being supported by the reclining member 37 from the back side. That is, according to this structure, the back support body 44 which has a very simple structure can be tilted while being stably supported by the tilting member 37 .

As shown in FIG. 10 , the back support body 44 has a guiding mechanism 76 for guiding the first reclining member 37A and the second reclining member 37B. The guide mechanism 76 forms a passing path of the reclining member 37 with the cover material 72B. One end of the guiding mechanism 76 shown in the figure is sewn to the cloth-like material 72B, and the other end is detachable to the cloth-like material 72B. When disassembling the seat back 72 from the back support body 44, the other end of the inducing mechanism 76 is disassembled from the cover cloth-like material 72B, and the reclining member 37 is installed and dismounted toward the seat back 72.

Next, the action when using the stroller 10 including the above configuration will be described.

In a state where the baby sits or lies on the seat 70 of the stroller 10 , the user holds the handle 30 and drives the stroller 10 . The seat seat 71 of the seat 70 is supported by the seat support 42 of the seat support unit 40 , and the seat back 72 of the seat 70 is stably supported by the back support 44 of the seat support unit 40 . Also, by utilizing the first to fourth mounting mechanisms 75a to 75d, the seat can be The support unit 40 and the body frame 20 stably hold the seat 70 . Thereby, the infant on the seat 70 will not feel excessive shaking or vibration, and the infant will be provided with excellent riding comfort.

In addition, in the conventional stroller, as a seat portion support body supporting the seat portion of the seat, for example, a three-frame frame made by bending a metal pipe is used. In such a conventional stroller, the seat support body composed of three frames supports the seat from below through the rigid frame material extending in the width direction. Therefore, regardless of the cushioning properties of the seat, infants can feel that the frame extending in the width direction abuts against the legs. As mentioned above, when the frame material abuts against the thighs and other legs of the infant, the riding comfort of the stroller will be reduced.

On the other hand, in the seat support unit 40 of the stroller 10 of this embodiment, the connection member 60 supporting the seat 70 from below is supported by the pair of side frame elements 50 . The connection member 60 includes, for example, cloth, leather, resin, etc., and is more flexible than the side frame elements 50 and is more easily deformed than the side frame elements 50 . Since the connection member 60 is provided, it is not necessary to arrange the front frame member 55 at the same position as the previous stroller, that is, at the same height as the side frame elements 50 . Therefore, it is possible to prevent the highly rigid frame material from abutting against the legs of the infant, thereby improving the riding comfort.

In the illustrated example, as shown in FIG. 5 , a first connecting member 60A is attached to a portion of the front end member 52 that overlaps with the side frame material 51 in the front-rear direction. That is, in the illustrated example, the side frame material 51 is also located in the region where the portion of the front end member 52 to which the first connecting member 60A is attached is located in the front-rear direction. In other words, the first connecting member 60A is attached to a portion of the front end member 52 covering the side frame material 51 in the front-rear direction. According to this specific example, the first connecting member 60A is arranged in the front, and the first connecting member 60A can be used to gently and stably support from below. Support the legs of infants and young children. In addition, when fixing the first connecting member 60A to the side frame element 50 with a fixture such as a rivet, the front end member 52 can be aligned with the front end portion of the side frame member 51 and fixed.

In addition, in the illustrated example, the seat support body 42 has a frame material 55 before connecting the pair of side frame elements 50 . However, the front frame member 55 is located behind the front end of the frontmost first connecting member 60A in the front-rear direction. According to this specific example, by providing the highly rigid front frame member 55, the distance between the pair of side frame elements 50 in the width direction can be maintained. Thereby, the connecting member 60 can be maintained in a tight state, and the infant can be supported more stably via the seat 70 . Moreover, since the front frame material 55 is located behind the front end of the first connecting member 60A, the front frame material 55 can be prevented from abutting against the legs of the infant, thereby improving the riding comfort of the stroller 10 .

Likewise, in the illustrated example, the front frame material 55 is located below the side frame material 51 of the side frame element 50 and is located behind the front end of the side frame element 50 . The front frame member 55 is located below the seat-shaped member 65 and is located behind the front end of the seat-shaped member 65 . According to this specific example, the front frame member 55 can be arranged below and behind the connecting member 60 attached to the side frame element 50 and the seat-shaped member 65 supported by the connecting member 60 . Thereby, the front frame material 55 and the part of the seat 70 which overlaps with the side frame element 50 in the front-rear direction and is supported from below by the side frame element 50 are separated in the up-down direction. Therefore, it is possible to prevent the front frame material 55 from abutting against the legs of the infant, thereby improving the riding comfort of the stroller.

In addition, it is also assumed that the seat 70 becomes dirty along with the use of the stroller 10 . In this case, the seat 70 can be detached from the stroller body 15, and the seat 70 can be washed and cleaned. Specifically, the first First, by releasing the first to fourth mounting mechanisms 75a to 75d, the holding of the seat 70 by the seat support unit 40 and the main body frame 20 is released. Next, the back support body 44 of the seat support unit 40 is pulled out from the receiving portion RP of the seat back 72 . As above, the seat 70 can be detached from the stroller body 15 very simply.

Here, in the conventional baby carriage, as explained as the prior art, it is impossible to detach and wash the base as the cloth product stretched widely from the baby carriage main body. The base is widely stretched on the three frames forming the seat support body and the three frames forming the back support body.

On the other hand, according to the present embodiment, the seat 70 is supported from below by the elongated connecting member 60 that bridges the pair of side frame elements 50 and extends in the width direction. Even if the connecting member 60 is not provided in the entire area between the pair of side frame elements 50 , it can stably support the infant on the seat 70 . In the previous stroller, the base was extended to approximately the entire area of the three frames in the front and rear directions. On the other hand, according to the present embodiment, the ratio of the length L (refer to FIG. 5 ) of the length L (refer to FIG. 5 ) of the side frame elements 50 in the front-rear direction to the length of the arrangement (occupancy) of the connecting member 60 in the front-rear direction can be set to 50% or less. You may further set it as 30% or less. In this way, the amount of cloth products that cannot be removed from the stroller 10 and washed can be reduced. Therefore, the hygienic aspect of the stroller 10 can be improved. In addition, the connecting member 60 can also be made of members other than cloth products, such as resin or leather which is more excellent in anti-fouling property than cloth products, and the hygienic level of the stroller 10 can also be greatly improved.

In addition, in the illustrated example, the plurality of connection members 60 are separated from each other in the front-rear direction and are mounted on the pair of side frame elements 50 . According to this specific example, an infant on the seat 70 can be efficiently and stably supported by the plurality of connecting members 60 arranged separately in the front-rear direction. That is, a One side can stably support infants, and one side can reduce the amount of connecting member 60. Therefore, the hygienic aspect of the stroller 10 can be further improved.

Furthermore, in the illustrated example, the seat support body 42 further has a crotch belt 11A attached to the connecting members 60 other than the first connecting member 60A located at the front among the plurality of connecting members 60 . According to this specific example, the frontmost first connecting member 60A is arranged in front of the position of the crotch belt 11A. The legs of the infant on the seat 70 can be stably supported by the frontmost first connecting member 60A. In particular, according to the flexible first connecting member 60A, the legs can be gently supported. In addition, it is also possible to stably prevent the front frame member 55 from coming into contact with the legs. According to these, the riding comfort of the stroller 10 can be greatly improved. Also, the crotch belt 11A can be held stably by the connection member 60 .

Moreover, according to this embodiment, the seat back 72 includes the accommodation part RP which receives the back support body 44, and the accommodation part RP opens downward. Therefore, the seat back 72 can be stably held by the back support 44 by preventing the size of the accommodating portion RP from becoming too large relative to the size of the back support 44 in advance. Therefore, the seat back 72 is stably maintained on the back support 44 even if the back support 44 has no previous base structure, that is, a frame structure such as a simple three-frame frame. Also, even if an infant riding on the stroller 10 leans on the seat back 72, it is possible to effectively prevent the seat back 72 from being greatly bent at its central portion. That is, even if the back support body 44 is set as a simple three-frame frame structure, it can stably support the infant on the seat 70 . Thereby, the amount of cloth products that cannot be unloaded from the stroller 10 and washed can be greatly reduced, and the hygienic aspect of the stroller can be greatly improved.

In addition, in the illustrated stroller 10 , the seat 70 is placed on the seat-shaped member 65 held by the connection member 60 . The seat-like member 65 is made of resin and has better anti-fouling properties than cloth products, and can be fully washed and cleaned by wiping or the like while it is installed on the stroller body 15 without changing.

The seat 70 cleaned and cleared is mounted on the body frame 20 again. First, the back support body 44 is inserted from the upper edge into the opening opened to the lower side of the storage part RP, and the back support body 44 is arranged in the storage part RP. Next, the seat seat portion 71 is attached to the seat portion support body 42 and the seat side portion 73 is attached to the main body frame 20 by using the first to fourth attachment mechanisms 75 a to 75 d.
