Technical Field

The present disclosure relates to a seat support assembly for a stroller and a stroller.

Background

Strollers having a seat support assembly and a cushioned seat on the seat support assembly are in widespread use. The seat support assembly has a seat support body facing the buttocks of the infant from below and a back support body facing the back of the infant from behind. In the stroller disclosed in patent document 1 (JP 2014-73701A), the seat support and the back support have three rims. The three frame has a pair of side portions and a connecting portion connecting end portions of the pair of side portions. The frame of the seat support opens rearward and the frame of the back support opens downward. In general, in order to prevent the cushion seat from falling off the seat support assembly, the seat support and the back support have bases that are stretched over three frames. The base is non-removably mounted to the frame and is maintained in tension.

The cushion seat is removably retained by the seat support assembly and is removable from the seat support assembly for washing. On the other hand, the base is not detachably attached to the three frames, and is maintained in a tensioned state. That is, the cloth product base, which is widely spread, cannot be detached from the stroller and washed.

Detailed Description

An embodiment of the present invention will be described below with reference to an example shown in the drawings.

Fig. 1 to 11 are views for explaining an embodiment of a seat support assembly and a stroller according to the present invention. Fig. 1 to 4 show the overall configuration of a specific example of a stroller or a stroller body. In addition, fig. 4-8 illustrate all or a portion of the seat support assembly. Fig. 9 and 10 mainly show the seat 70. The configuration shown in some of the drawings may be omitted from other drawings.

As shown in fig. 1, the stroller 10 of the present embodiment includes a stroller body 15 and a seat 70 supported by the stroller body 15. The stroller body 15 includes a seat support assembly 40 for supporting the seat 70 and a body frame 20 for supporting the seat support assembly 40. The seat 70 is a portion where an infant sitting on the stroller 10 sits or lies. The seat 70 can be removed from the seat support assembly 40 for washing. In the stroller 10 described below, as a design for improving the sanitary level, the amount of cloth that cannot be detached from the stroller 10 for washing is reduced.

The constituent elements of the stroller 10 will be described in order. As shown in fig. 1 and 2, the illustrated stroller 10 and stroller body 15 integrally have a substantially symmetrical configuration about a surface located at the center in the lateral direction and extending in the front-rear direction and the up-down direction.

Unless otherwise specified in the present specification, terms such as "front", "rear", "upper", "lower", "front-rear direction", and "up-down direction" with respect to the stroller and its constituent elements mean "front", "rear", "upper", "lower", "front-rear direction", and "up-down direction" with respect to an infant seated in the stroller in a deployed state and its constituent elements. More specifically, the "front-rear direction" refers to a direction connecting the lower left and upper right of the paper surface in fig. 1 and 2, and corresponds to the left-right direction of the paper surface in fig. 3. Unless otherwise specified, "front" refers to the side toward which the infant is seated, and the lower left side of the sheet in fig. 1 and 2 and the left side of the sheet in fig. 3 are the front sides. On the other hand, the "vertical direction" refers to a direction orthogonal to the running surface of the stroller. Therefore, in the case where the running surface is a horizontal surface, "up-down direction" means a vertical direction. The "lateral direction" refers to the width direction, and is a direction perpendicular to any one of the "front-back direction" and the "up-down direction". The "inner side" or "inner side" in the width direction (lateral direction) indicates a side of the width direction near the center of the stroller, and the "outer side" or "outer side" in the width direction (lateral direction) indicates a side of the width direction far from the center of the stroller. Further, "back side" used in connection with a seat support assembly or the like refers to the side opposite the side on which the infant in the stroller is seated. Therefore, the "back side" is generally referred to as the rear side or the lower side.

First, the stroller body 15 will be described. The illustrated stroller body 15 is configured to be foldable. As described above, the stroller main body 15 includes the main body frame 20 and the seat support assembly 40, but first, the main body frame 20 and the seat support assembly 40 are not clearly distinguished, and each constituent element that allows the stroller main body 15 to be configured to be foldable will be described.

As shown in fig. 2, the stroller body 15 includes a pair of front legs 21 disposed on the left and right sides and a pair of rear legs 23 disposed on the left and right sides. The stroller main body 15 further includes a 1 st link L1, a 2 nd link L2, a 3 rd link L3, and a 4 th link L4 disposed on the left and right sides, respectively. The front leg 21, the rear leg 23, and the 1 st to 4 th links L1 to L4 function as links for making the stroller main body 15 foldable and expandable.

As shown in fig. 2, the front legs 21 hold the front wheels 22 rotatable at lower end portions thereof. The front wheel 22 constitutes a caster wheel, which is rotatable and revolvable. The rear legs 23 hold the rear wheels 24 rotatable at lower end portions thereof. For example, the front leg 21 and the rear leg 23 are formed by using a metal tube such as an aluminum alloy.

As shown in fig. 2, the upper end portion of the front leg 21 is rotatably (swingably) connected to the front portion of the 1 st link L1 disposed on the corresponding side (left side or right side). The upper end portion of the rear leg 23 is rotatably (swingably) connected to the front portion of the 1 st link L1 arranged on the corresponding side (left side or right side). For example, the 1 st link L1 can be configured using a resin molded product. In the illustrated example, the 1 st link L1 can function as a handle.

As can be understood from fig. 3, the 2 nd link L2 is rotatably (swingably) connected to the rear end portion of the 1 st link L1 arranged on the corresponding side (left side or right side). In the illustrated example, the 2 nd link L2 is configured as a part of the grip 30. The grip 30 has a U-shape overall. The grip 30 includes a pair of shaft portions 31 and a connecting portion 32 connecting the pair of shaft portions 31. Each shaft portion 31 constitutes a 2 nd link L2. The connecting portion 32 connects upper end portions of the pair of shaft portions 31. For example, a metal tube such as aluminum alloy is used to construct the grip 30.

As shown in fig. 2 and 3, the 3 rd link L3 is rotatably connected to the rear leg 23 disposed on the corresponding side (left side or right side). For example, the 3 rd link L3 can be formed using a metal tube such as an aluminum alloy or a resin molded product. In the illustrated example, the 3 rd link L3 is rotatably connected at its lower end portion to the middle portion of the rear leg 23.

As shown in fig. 2 and 3, the 4 th link L4 is rotatably (swingably) connected to the front leg 21 disposed on the corresponding side (left side or right side). In the illustrated example, the 4 th link L4 is rotatably connected at a front end portion thereof to a middle portion of the front leg 21. As will be described in detail later, the 4 th link L4 constitutes a part of the seat support assembly.

In the illustrated example, the 2 nd link L2, the 3 rd link L3, and the 4 th link L4 disposed on the same side (left side or right side) in the width direction are rotatably connected to each other using the same shaft member 35 (see fig. 3). The shaft member 35 penetrates the 2 nd link L2, the 3 rd link L3 and the 4 th link L4. According to this configuration, the 2 nd link L2, the 3 rd link L3, and the 4 th link L4 can mutually rotate about an axis line that coincides with the central axis line of the shaft member 35.

As shown in fig. 2, the stroller main body 15 includes a front link 26 that links between the pair of front legs 21 and a rear link 27 that links between the pair of rear legs 23 as constituent elements extending in the lateral direction. The front connector 26 functions as a pedal. For example, the front joint 26 and the rear joint 27 may be formed using a metal tube such as an aluminum alloy or a resin molded product. Further, a flexible protection member 28 is detachably provided between the pair of 1 st links L1.

The stroller body 15 having the above-described configuration can be folded by relatively rotating the respective constituent members. Specifically, the grip 30 constituting the 2 nd link L2 is temporarily lifted upward and then pushed downward, whereby the 3 rd link L3 is rotated in the clockwise direction in fig. 3 with respect to the rear leg 23. With this operation, the 1 st link L1 and the 4 th link L4 rotate in the clockwise direction in fig. 3 with respect to the 2 nd link L2. By such an operation, the grip 30 and the front leg 21 come close to each other while maintaining a substantially parallel relationship in a side view, and the position of the grip 30 is lowered. As described above, the stroller main body 15 can be folded. In the folded state, the dimensions in the front-rear direction and the up-down direction of the stroller 10 can be reduced. On the other hand, the stroller main body 15 may be unfolded from the folded state by performing the reverse step to the above-described folding operation.

In the above-described configuration of the stroller body 15, the side frame members 50 are included in the seat support assembly 40, and other configurations are included in the body frame 20.

Next, the seat support assembly 40 will be described in detail. As shown in fig. 2 to 3, the seat support assembly 40 includes a seat support 42 and a back support 44. The seat support 42 faces buttocks of the infant seated in the stroller 10. The back support 44 faces the back of the infant seated in the stroller 10.

First, the seat support 42 of the seat support assembly 40 will be described with reference to fig. 4 to 7. In fig. 1 to 4, a part or all of the seat support assembly 40 shown in fig. 4 to 7 may be omitted.

Fig. 4 and 5 are perspective and top views, respectively, showing the seat support assembly 40, and fig. 6 is a cross-sectional view taken along the VI-VI line of fig. 5. As shown in fig. 4 to 6, the seat support 42 includes a pair of side frame elements 50, a connecting member 60, and a sheet-like member 65 as main constituent elements. In addition, in the perspective view of fig. 7, the seat support assembly 40 in a state in which the sheet-like member 65 is removed from the same direction as in fig. 4 is shown.

As shown in fig. 2, the side frame member 50 constitutes the 4 th link L4 as described above. The pair of side frame members 50 are arranged apart in the width direction. Each side frame member 50 extends in the front-to-rear direction. The side frame member 50 is rotatably connected at a front end portion thereof to a middle portion of the front leg 21. Further, the side frame member 50 is rotatably connected at its rear end portion to the lower end portion of the 2 nd link L2 and the upper end portion of the 3 rd link L3.

As shown in fig. 4, the side frame member 50 has a side frame member 51 extending in the front-rear direction, a front end member 52 fixed to a front end portion of the side frame member 51, and a rear end member 53 fixed to a rear end portion of the side frame member 51. The side frame members 51 are formed of, for example, metal pipes such as aluminum alloy. For example, the front end member 52 and the rear end member 53 may be formed of a resin molded product. As best shown in fig. 4, the front end member 52 is provided with a bearing hole 52a, and the bearing hole 52a is provided for passing a shaft (not shown) for rotatably coupling the side frame member 50 and the front leg 21. The distal end member 52 is provided with a through hole 52b through which the coupling member 60 passes. The rear end member 53 is formed with a bearing hole (not shown) through which the shaft member 35 passes.

Next, the connecting members 60 are erected on the pair of side frame elements 50. The connecting member 60 is provided between the pair of side frame members 50, and supports the seat 70 and the infant from below. The connecting member 60 preferably has flexibility and may further have elasticity. According to the coupling member 60, the infant can be supported gently, and the riding comfort of the stroller 10 can be improved.

As shown in fig. 5, the coupling member 60 is an elongated member extending in the width direction. The width W of the connecting member 60 in the front-rear direction is very short with respect to the length L of the side frame element 50 in the front-rear direction. In the illustrated example, the connecting member 60 is a band-shaped member. However, the connecting member 60 is not limited to this example, and may be a member having a very small width W, which may be referred to as a string. As the connecting member 60, a cloth tape, a cloth rope, a belt-like member or a rope-like member made of natural leather or synthetic leather, a resin belt-like member or a rope-like member, or the like, which is produced by sewing cloth, can be used.

The plurality of coupling members 60 may be spaced apart from each other in the front-rear direction and may be mounted on the pair of side frame members 50. As best shown in fig. 5, in the illustrated seat support assembly 40, three coupling members 60 are spaced apart from each other in the fore-and-aft direction and are mounted to a pair of side frame members 50. However, the present invention is not limited to the illustrated example, and two connecting members 60 may be provided between the pair of side frame members 50, or four or more connecting members 60 may be provided. When a plurality of coupling members 60 are used, the physical characteristics and the configuration may be changed according to the arrangement of the coupling members 60. For example, the strength of the connecting member 60 located at the rearmost side in the front-rear direction may be made stronger than the strength of the other connecting members 60. The width W of the connecting member 60 located at the rearmost side in the front-rear direction may be wider than the width of the other connecting members 60. Further, the elongation of the connecting member 60 located at the forefront in the front-rear direction may be made larger than the elongation of the other connecting members 60.

The ratio of the length of the front-rear direction connecting member 60 to the length L of the front-rear direction side frame element 50 may be 50% or less, or 30% or less. The "length of the coupling members 60 in the front-rear direction" is the sum of the widths W of the coupling members 60 in the front-rear direction when the coupling members 60 are provided. In the case where the ratio is small, it is preferable not only from the viewpoint of manufacturing cost due to reduction of materials used but also from the viewpoint of hygienic aspects. The coupling member 60 is supposed to be not detached from the side frame element 50 because it should be maintained in a tensioned state. Cleaning and sweeping the connecting member 60, which cannot be removed, is troublesome and difficult. Therefore, it is preferable to shorten the length of the connecting member 60 in the front-rear direction as much as possible.

From this point, it is preferable that the plurality of connecting members 60 are spaced apart from each other in the front-rear direction and are erected on the pair of side frame members 50. According to this specific example, the plurality of coupling members 60 arranged so as to be dispersed in the front-rear direction can effectively and stably support the infant on the seat 70. That is, the infant can be stably supported, and the amount of the connecting member 60 can be reduced. Thus, the hygiene level of the stroller can be further improved.

As shown in fig. 1, the stroller 10 includes a seat belt 11 for fixing an infant to a seat 70. The seat belt 11 includes a crotch belt 11A passing through the crotch of the infant, a waist belt 11B detachably attached to the crotch belt 11A by the waist of the infant, and a shoulder belt 11C detachably attached to the crotch belt 11A by the shoulder of the infant. As clearly shown in fig. 4 and 7, the crotch belt 11A is attached to one connecting member 60 in the illustrated seat support 42. Specifically, the tubular portion is formed at the base end portion of the crotch belt 11A by sewing or the like, for example, and the connecting member 60 passes through the tubular portion of the crotch belt 11A.

From the viewpoint of effectively functioning the seat belt 11, the crotch belt 11A preferably extends from a position slightly forward of the center in the front-rear direction in the seat portion. In the illustrated example, the 2 nd coupling member 60B is provided at a position slightly shifted forward from the center in the front-rear direction in the seat portion, and is located in the middle in the front-rear direction. As a result, in the illustrated example, the crotch belt 11A is attached to the coupling members other than the 1 st coupling member 60A located at the forefront in the front-rear direction and the 3 rd coupling member 60C located at the rearmost side in the front-rear direction. According to such an example, the crotch belt 11A can be stably held by the connecting member 60, and the seat belt 11 can be effectively used.

As shown in fig. 5, the seat support 42 has the 1 st coupling member 60A located at the forefront in the front-rear direction than the 2 nd coupling member 60B to which the crotch belt 11A is attached. The forefront 1 st connecting member 60A can stably support the legs of the infant on the seat 70. In particular, according to the 1 st connecting member 60A having flexibility, the leg portion can be gently supported, and the riding comfort of the stroller 10 can be improved.

As shown in fig. 5, the seat support 42 has a 3 rd coupling member 60C located rearmost in the front-rear direction of the 2 nd coupling member 60B to which the crotch belt 11A is attached. The seat surface of a typical stroller mainly receives the weight of an infant rearward of the extended position of the crotch strap. Therefore, the infant can be stably supported by the 3 rd coupling member 60C. In particular, according to the 3 rd coupling member 60C having high strength, the stability of the infant support can be increased, and the riding comfort of the stroller 10 can be improved.

As shown in fig. 6, the coupling members 60 are attached to the side frame members 50 on the corresponding sides at both end portions thereof. Each of the connecting members 60 is attached to the inner surface of the corresponding side frame element 50 in the width direction by extending above, outside and below the side frame element 50 in the width direction at its end portion. 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 member 51), and then sequentially contacts the upper and lower surfaces of the side frame element 50 (side frame member 51), the outer surface in the width direction of the side frame element 50 (side frame member 51), and the upper and lower surfaces of the side frame element 50 (side frame member 51), and then further extends inward in the width direction. According to this specific example, the connecting member 60 can be more firmly attached to the side frame element 50. Further, since the length of the connecting member 60 can be ensured to be long, the infant can be supported gently, and for example, the impact from the running surface of the stroller 10 can be absorbed effectively. Further, since the connecting member 60 is attached from the inner side in the width direction of the side frame member 50, the attachment portion is inconspicuous, and the appearance of the stroller 10 can be improved.

In the example shown in fig. 6, the connecting member 60 is fixed to the side frame element 50 by a fixing member 63 such as a rivet. As shown in fig. 5, the 2 nd and 3 rd coupling members 60B and 60C are attached to the side frame members 51 around the side frame members 51 of the side frame element 50. That is, the 2 nd and 3 rd coupling members 60B and 60C are attached to the inner surfaces of the side frame members 51 by extending in this order on the upper side, the outer sides in the width direction, and the lower sides of the side frame members 51 of the side frame members 50 on the corresponding sides at the end portions thereof.

As shown in fig. 5 and 7, the 1 st connecting member 60A is attached to the front end member 52. However, at the position where the 1 st coupling member 60A is mounted, there is a side frame member 51 in the front end member 52. A through hole 52b is provided in the front end member 52 at a position below the side frame member 51. The 1 st connecting member 60A extends from the outer side to the inner side in the width direction of the side frame element 50 through the through hole 52b. By using the through hole 52b, the 1 st coupling member 60A can be stably attached to the front end member 52 having a complicated shape.

Next, a sheet-like member (sheet-like member) 65 will be described. The sheet-like member 65 is a resin member formed in a sheet-like or plate-like shape. As shown in fig. 4 to 6, the sheet-like member 65 is supported by the connecting member 60. As shown in fig. 8, the seat 70 is disposed on the sheet-like member 65, and is supported by the sheet-like member 65 from below. The resin sheet-like member 65 preferably has a certain degree of flexibility. The sheet-like member 65 can be given flexibility by adjusting the resin material, the thickness, or the like. As an example, the thickness of the sheet-like member 65 may be set to 0.5mm to 2mm, and further may be set to 0.8mm to 1.5 mm. As the resin material for the sheet-like member 65, polypropylene, polycarbonate, polyethylene terephthalate can be exemplified.

As described above, according to the seat support 42 provided with the resin sheet-like member 65 supported by the coupling member 60, the coupling member 60 supports the infant on the seat 70 in a wide area via the sheet-like member 65. Therefore, the sheet-like member 65 and the connecting member 60 having a certain degree of flexibility can stably support the infant with a more uniform force. Further, since the coupling members 60 support the infant via the sheet-like members 65, the number of the coupling members 60 and the width W in the front-rear direction can be reduced, and the amount of the coupling members 60 can be reduced. Further, the sheet-like member 65 made of resin is excellent in stain resistance as compared with cloth or the like, and can be sufficiently cleaned and cleaned while being kept attached to the stroller 10. For example, the sheet-like member 65 made of resin can easily remove dirt by dry or wet wiping. That is, by providing the sheet-like member 65, it is possible to stably support an infant to improve riding comfort, and to further improve the sanitary level of the stroller.

As shown in fig. 5, the length of the sheet-like member 65 in the front-rear direction is substantially the same as the length of the side frame member 50 in the front-rear direction. Similarly, the length of the sheet-like member 65 in the width direction is substantially the same as the distance in the width direction between the width-direction outer sides of the pair of side frame elements 50. That is, the illustrated sheet-like member 65 extends over substantially the entire area of the seat support 42 in plan view.

Preferably, the pair of side frame members 50 are located at a position at least partially overlapping the sheet-like member 65 in a top view as shown in fig. 5. According to this configuration, the sheet-like member 65 is supported from below by the pair of side frame elements 50. Therefore, the widthwise outer portion of the sheet-like member 65 can be prevented from sagging and bending. This allows the infant to be supported more stably via the sheet-like member 65. Further, since the support state by the sheet-like member 65 is stable, the number of the coupling members 60 or the width W in the front-rear direction can be reduced, and the area of the coupling members 60 can be reduced.

In the illustrated example, the sheet-like member 65 is provided with a hole 65a through which the connecting member 60 passes. The coupling member 60 passes through the hole 65a of the sheet-like member 65, whereby the sheet-like member 65 is held by the coupling member 60. According to such a holding method, the sheet-like member 65 can be slightly moved relative to the connecting member 60. By such play, an impact from the road surface or the like can be absorbed, and the riding comfort of the stroller 10 can be improved.

In particular, as shown in fig. 5 and 6, the sheet-like member 65 is provided with four holes 65a through which one connecting member 60 passes. In the illustrated example, the three coupling members 60 are disposed apart in the front-rear direction. Therefore, four holes are provided for each connecting member 60, and a total of 12 holes 65a are provided in the sheet-like member 65. Each of the connecting members 60 supports the sheet-like member 65 from below at both end portions and a central portion in the longitudinal direction thereof. According to this configuration, the sheet-like member 65 is supported from below by the connecting member 60, and thus sagging at the widthwise outer portion or sagging at the widthwise central portion can be suppressed. This allows the connecting member 60 to more stably support the infant via the sheet-like member 65. Further, since the support state by the sheet-like member 65 is stable, the number of the coupling members 60 or the width W in the front-rear direction can be reduced, and the area of the coupling members 60 can be reduced.

As described above, the crotch belt 11A is attached to the 2 nd coupling member 60B. The crotch belt 11A is located at the center in the width direction. Further, a belt hole 65b is provided at a position of the sheet-like member 65 facing the crotch belt 11A. The crotch belt 11A passes through the belt hole 65b and extends upward from below the sheet-like member 65.

As shown in fig. 6, the end surface of the sheet-like member 65 may be covered with the covering 67. The covering material 67 may be provided so as to cover one or more of the side end face, the front end face, and the rear end face of the sheet-like member 65, or may be provided so as to cover the end face over the entire circumference of the sheet-like member 65. As an example, the wrapping 67 may be made of cloth. By providing the covering member 67, the appearance can be improved and the operability is excellent.

As shown clearly in fig. 7, the seat support body 42 further includes a front frame member 55 and an intermediate frame member 57 as members extending in the width direction. For example, the front frame member 55 and the intermediate frame member 57 are formed of a metal tube such as an aluminum alloy or a resin molded product. The front frame member 55 and the intermediate frame member 57 are positioned between the pair of side frame members 50, and maintain the separation distance between the pair of side frame members 50 in the width direction to be equal to or greater than a predetermined value. This can maintain the connecting member 60 in a tensioned state, and can support the infant more stably.

As shown in fig. 7, the front frame member 55 and the intermediate frame member 57 are located below each of the side frame members 50, the coupling members 60, and the seat 70 in the up-down direction. As shown in fig. 5, the front frame member 55 is located rearward of the front end of the side frame member 50 in the front-rear direction. The front frame member 55 is located rearward of the front ends of the side frame members 51 in the front-rear direction. The front frame member 55 is located rearward of the front end of the 1 st coupling member 60A in the front-rear direction. The front frame member 55 is located rearward of the front end of the sheet-like member 65 in the front-rear direction. The front frame member 55 disposed at such a position is less likely to contact the legs of an infant sitting on the stroller 10.

Next, the back support 44 will be described. As shown in fig. 3, the back support 44 is rotatable relative to the seat support 42. The back support 44 can recline by swinging relative to the seat support 42. As shown in fig. 4, the back support 44 includes a pair of back frame portions 45 that are separated in the width direction, and a back connection frame portion 46 that connects the pair of back frame portions 45. In the illustrated example, the back connection frame 46 is connected to an end of the back frame 45 on a side separated from the seat support 42. The back support 44 is configured as a three-sided frame.

Specifically, the back connection frame portion 46 includes a back frame member 47 formed in a U shape with an angular, and connection end members 48 fixed to both end portions of the back frame member 47. As best shown in fig. 4, the connecting end member 48 is provided with a bearing hole 48a through which the shaft member 35 passes. The shaft member 35 is connected to the back support 44 and the seat support 42 swingably through a bearing hole 48a of the connection end member 48 and a bearing hole, not shown, of the rear end member 53 of the side frame element 50. The back frame member 47 is formed of a metal tube such as aluminum alloy, for example. The connection end member 48 can be formed of, for example, a resin molded product.

As shown in fig. 8, the seat support assembly 40 further includes a connection mechanism 68 that connects the sheet-like member 65 and the intermediate frame 57. By providing the connection mechanism 68, the position of the sheet-like member 65 in the seat support 42 can be stabilized. The connection mechanism 68 may be a sheet-like member, a belt-like member, or a string-like member. In the illustrated example, the connection mechanism 68 is formed as a cloth-like member, and both edge portions are sewn to the rear edge portion of the sheet-like member 65. The intermediate frame member 57 is sewn at both edge portions to the connecting mechanism 68 of the sheet-like member 65.

Next, a seat (seat) 70 will be described mainly with reference to fig. 8 to 10. Here, fig. 8 is a side cross-sectional view showing the seat 70 together with the seat support assembly 40, fig. 9 is a perspective view showing the seat 70, and fig. 10 is a view showing the seat 70 attached to the stroller 10 from the rear. In fig. 1 to 7, part or all of the seat 70 shown in fig. 8 to 10 may be omitted.

As best shown in fig. 9, the seat 70 has a seat portion 71 and a seat back portion 72. The seat portion 71 is supported by the seat support body 42 of the seat support assembly 40. The seat portion 71 is provided with a bandpass hole 71A (see fig. 1) through which the crotch strap 11A passes. The seat back 72 is connected to the seat portion 71 from the rear. The seat back 72 is supported by the back support 44 of the seat support assembly 40. The seat 70 is a part for seating or lying an infant.

As shown in fig. 9, the seat 70 has a 1 st mounting mechanism 75a provided at a front edge portion of the seat portion 71 and a 2 nd mounting mechanism 75b provided at both side edge portions of the seat portion 71. The seat portion 71 is detachably attached to the seat portion support body 42 by the 1 st attachment mechanism 75a and the 2 nd attachment mechanism 75b.

The 1 st mounting mechanism 75a is provided with a pair of mounting mechanisms separated in the width direction. As shown in fig. 8, the 1 st mounting mechanism 75a connects the front edge portion of the seat portion 71 with the front frame member 55. The portion of the seat portion 71 extending forward of the seat support 42 is folded back at the front end of the seat support 42. That is, the seat portion 71 covers the seat portion support body 42 from the front in a state of being attached to the seat portion support body 42.

The 1 st attachment mechanism 75a may be configured as one or two belt-like members or a string-like member, for example. The front end portion of the seat portion 71 can be attached to the seat support 42 by fastening one band-like or string-like member fixed to the seat portion 71 by a fastening member such as a knot or a hook-and-loop fastener or a button, and by folding back the member at the front frame member 55 to form two front and rear portions. Alternatively, the front end portion of the seat portion 71 may be attached to the seat support 42 by fixing two belt-like or string-like members fixed to the seat portion 71 with the front frame member 55 interposed therebetween and tying or fixing the members by a fastening tape, a button, or the like.

As can be understood from fig. 9, the 2 nd mounting mechanism 75b couples the side edge portion of the seat portion 71 to the side frame member 50. The specific configuration of the 2 nd attachment mechanism 75b may be the same as that of the 1 st attachment mechanism 75 a.

As shown in fig. 8 and 10, the seat back 72 includes a seat back main body 72A and a cover cloth 72B covering the seat back main body 72A from the back side. The seat back body 72A contacts the back or head of the infant. The cover cloth 72B forms a housing portion RP that houses the back support 44 with the seat back main body 72A. The cover cloth 72B is sewn to the seat back main body 72A at both side edge portions and an upper edge portion. As a result, as shown in fig. 8, the accommodating portion RP opens toward the seat support 42 side. That is, the accommodating portion RP is opened downward.

The seat portion 71 and the seat back main body 72A of the seat back 72 are portions that come into contact with the infant. Therefore, the seat portion 71 and the seat back main body 72A preferably have cushioning properties. For example, the seat portion 71 and the seat back main body 72A may include: a surface layer, a lining sewn to the surface layer at the peripheral edge portion, cotton, sponge, resin, etc. accommodated between the surface layer and the lining. On the other hand, the hood cloth 72B does not require cushioning. The cover cloth 72B may be formed using cloth or mesh. In the hood cloth 72B shown in fig. 10, a mesh cloth is used in a lower region near the opening, and a fine mesh cloth is used in an upper region distant from the opening. According to the hood cloth 72B shown in fig. 10, the back support 44 can be easily inserted into the accommodating portion RP of the seat back 72 through the lower opening, and the seat back 72 can be stably held by the back support 44 by inserting the back support 44 deep into the accommodating portion RP.

As shown in fig. 9, the seat 70 also has a pair of seat sides 73. The seat side portion 73 is connected to the seat portion 71 and the seat back portion 72 from both sides. The seat side portion 73 may be configured to have cushioning properties in the same manner as the seat portion 71 and the seat back portion 72. The seat side portion 73 may be made of cloth or the like without having cushioning properties. In fig. 8 and 10, the seat side 73 is not illustrated.

As shown in fig. 1, the seat side 73 is detachably mounted to the main body frame 20 of the stroller main body 15. According to this specific example, the seat 70 can be stably held by the main body frame 20 and the seat support assembly 40.

As a specific configuration, as shown in fig. 9, each seat side 73 has a 3 rd attachment mechanism 75c and a 4 th attachment mechanism 75d at a side edge portion on a side away from the seat back 72. The 3 rd mounting mechanism 75c is mounted to the main body frame 20, for example, in the same manner as the 1 st mounting mechanism 75a and the 2 nd mounting mechanism 75 b. The 4 th attachment mechanism 75d has a different configuration from the 3 rd attachment mechanism 75c, and is attached to the main body frame 20. The 4 th attachment mechanism 75d can be configured as a fastener such as a button that can be fixed to a fastener attached to the main body frame 20. The seat side portion 73 has different types of attachment mechanisms 75c and 75d, so that the seat 70 can be attached to the main body frame 20 more stably. In the illustrated example, the seat side 73 is detachable from the 2 nd link L2 of the main body frame 20.

As shown in fig. 10, 3, and the like, the stroller 10 (stroller body 15) further includes a reclining member 37. The reclining member 37 is connected to the main body frame 20, and supports the back support 44 of the seat support assembly 40 from the back side. The reclining member 37 supports the back support 44 from the back side by being connected to the main body frame 20 and being located at the back side of the back support 44.

As best shown in fig. 10, the recliner members 37 are mounted to a pair of portions of the main body frame 20 that flank the seat support assembly 40 (back support 44). The length of the recliner 37 between the pair of sections is variable. As shown in fig. 3, by changing the length of the reclining member 37, the inclination angle of the back support 44 with respect to the seat support 42 can be changed. That is, the back support 44 can be reclined.

In the illustrated example, the recliner 37 is mounted to the 2 nd link L2 at both ends thereof. Specifically, the reclining member 37 includes a 1 st and 2 nd reclining members 37A and 37B, and an adjusting member 37C, which are elongated in a string-like or belt-like manner. The 1 st reclining member 37A is fixed at one end thereof to the 2 nd link L2 of one side. The 1 st reclining member 37A extends from the one 2 nd link L2. The 2 nd reclining member 37B is fixed at one end thereof to the other 2 nd link L2. The 2 nd reclining member 37B extends from the other 2 nd link L2. The adjustment member 37C may be fixed to any position of the 1 st reclining member 37A and the 2 nd reclining member 37B as in a clip. Alternatively, the adjustment member 37C may be fixed to the other end of the 1 st reclining member 37A, and further fixed to any position of the 2 nd reclining member 37B.

The reclining angle of the back support 44 is determined by the total length of the length from the one end of the 1 st reclining member 37A to the adjustment piece 37C and the length from the one end of the 2 nd reclining member 37B to the adjustment piece 37C. When the total length becomes longer, the back support 44 is laid down (laid down) as indicated by the two-dot chain line in fig. 3. Here, in the state shown by the two-dot chain line in fig. 3, the length of the reclining member 37 between the pair of 2 nd links L2 is set to the longest length. That is, the position of the two-dot chain line in fig. 3 is the position where the back support 44 is most reclined.

The back support 44 can be pressed from the position shown by the two-dot chain line and raised. Therefore, in the illustrated example, the longest length of the reclining member 37 between the pair of 2 nd links L2 is a length that the reclining member 37 cannot go beyond the back support 44 pulled up by hand pressing or the like. Thus, the reclining member 37 does not accidentally go out to the front of the back support 44. Therefore, the back support 44 can be effectively prevented from being laid down rearward without being supported by the reclining member 37 from the rear surface side. That is, according to this configuration, the back support 44 having an extremely simple configuration can be reclined, and can be stably supported by the reclining member 37.

As shown in fig. 10, the back support 44 has a guide mechanism 76 for guiding the 1 st reclining member 37A and the 2 nd reclining member 37B. The guide mechanism 76 forms a passage path for the reclining member 37 with the cover cloth 72B. One end of the guide mechanism 76 is sewn to the cloth 72B, and the other end is detachable from the cloth 72B. When the seat back 72 is attached to and detached from the back support 44, the other end of the guide mechanism 76 is attached to and detached from the cover cloth 72B, and the reclining member 37 is attached to and detached from the seat back 72.

Next, the operation of the stroller 10 constructed as described above in use will be described.

In a state where the infant sits or lies on the seat 70 of the stroller 10, the user grips the grip 30 and walks the stroller 10. The seat portion 71 of the seat 70 is supported by the seat support body 42 of the seat support assembly 40, and the seat back 72 of the seat 70 is stably supported by the back support body 44 of the seat support assembly 40. Further, by using the 1 st to 4 th mounting mechanisms 75a to 75d, the seat 70 can be stably held by the seat support assembly 40 and the main body frame 20. This prevents the infant on the seat 70 from feeling excessive shake or vibration, and provides excellent riding comfort for the infant.

However, in the conventional stroller, as a seat support for supporting a seat, for example, a three-frame manufactured by bending a metal tube is used. In such a conventional stroller, a seat support body constituted by a three-sided frame supports a seat from below by a frame member having rigidity extending in the width direction. Therefore, even if the seat has more cushioning, the infant can feel that the frame member extending in the width direction is in contact with the leg portion. As described above, the frame member contacts the legs such as thighs of the infant, and thus the riding comfort of the stroller is reduced.

On the other hand, in the seat support assembly 40 of the stroller 10 of the present embodiment, the coupling member 60 that supports the seat 70 from below is supported by the pair of side frame members 50. The connecting member 60 is made of, for example, cloth, leather, resin, or the like, and is more flexible than the side frame element 50 and is more easily deformed than the side frame element 50. Since the coupling member 60 is provided, the front frame member 55 does not need to be provided at the same position as in the conventional stroller, that is, at the same height as the side frame member 50. Therefore, the high-rigidity frame material can be prevented from abutting the legs of the infant, and riding comfort can be improved.

In the illustrated example, as shown in fig. 5, the 1 st connecting member 60A is attached to a portion of the front end member 52 located in a region overlapping the side frame member 51 in the front-rear direction. That is, in the illustrated example, the side frame member 51 is also located in a region of the front end member 52 where the 1 st connecting member 60A is mounted in the front-rear direction. In other words, the 1 st connecting member 60A is attached to a portion of the front end member 52 that covers the side frame member 51 in the front-rear direction. According to this specific example, the 1 st connecting member 60A is disposed in the front, and the legs of the infant can be gently and stably supported from below by using the 1 st connecting member 60A. In addition, when the 1 st connecting member 60A is fixed to the side frame element 50 using a fastener such as a rivet, the front end member 52 can be fixed in correspondence with the front end portion of the side frame element 51.

Further, in the illustrated example, the seat support 42 has a front frame member 55 that joins the pair of side frame elements 50. However, the front frame member 55 is located rearward of the front end of the forefront 1 st coupling member 60A in the front-rear direction. According to this specific example, by providing the front frame member 55 with high rigidity, the interval between the pair of side frame members 50 in the width direction can be maintained. This can maintain the connecting member 60 in a tensioned state, and can support the infant via the seat 70 more stably. Further, since the front frame member 55 is located rearward of the front end of the forefront 1 st connecting member 60A, contact between the front frame member 55 and the legs of the infant can be avoided, and the riding comfort of the stroller 10 can be improved.

Likewise, in the illustrated example, the front frame member 55 is located below the side frame members 50 and rearward of the front ends of the side frame members 50. The front frame member 55 is located below the sheet-like member 65 and behind the front end of the sheet-like member 65. According to this specific example, the front frame member 55 can be disposed below and behind the coupling member 60 attached to the side frame element 50 and the sheet-like member 65 supported by the coupling member 60. Therefore, the front frame member 55 can be prevented from abutting the legs of the infant, and the riding comfort of the stroller can be improved.

Further, a situation is also contemplated in which the seat 70 becomes dirty with 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 cleaned. Specifically, first, the 1 st to 4 th mounting mechanisms 75a to 75d are released to release the seat 70 from the seat support assembly 40 and the main body frame 20. Next, the back support 44 of the seat support assembly 40 is pulled out from the accommodation portion RP of the seat back 72. As described above, the seat 70 can be removed from the stroller body 15 extremely easily.

As described in the background art, in the conventional stroller, the base serving as the cloth product, which is widely spread, cannot be detached from the stroller body and washed. The base is widely provided on a frame constituting the seat support and a frame constituting the back support.

On the other hand, according to the present embodiment, the seat 70 is supported from below by the elongated coupling members 60 that extend in the width direction and are provided to the pair of side frame members 50. The infant on the seat 70 can be stably supported even if the coupling member 60 is not provided in the entire region between the pair of side frame members 50. In the conventional stroller, the base extends over substantially the entire area of the three frames in the front-rear direction. In contrast, according to the present embodiment, the ratio of the length of the front-rear direction connecting member 60 to the length L (see fig. 5) of the front-rear direction side frame element 50 can be set to 50% or less, and further can be set to 30% or less. In this way, the amount of cloth that cannot be removed from the stroller 10 and washed can be reduced. Thus, the hygiene level of the stroller 10 can be improved. The connecting member 60 may be made of a material other than the cloth, for example, a resin or leather having more excellent stain resistance than the cloth, and the sanitary surface of the stroller 10 may be greatly improved.

In the illustrated example, the plurality of coupling members 60 are provided to the pair of side frame members 50 so as to be spaced apart from each other in the front-rear direction. According to this specific example, the plurality of coupling members 60 arranged so as to be spaced apart in the front-rear direction can effectively and stably support the infant on the seat 70. That is, the infant can be stably supported, and the amount of the connecting member 60 can be reduced. Thus, the hygiene level of the stroller 10 can be further improved.

Further, in the illustrated example, the seat support 42 further includes a crotch band 11A, and the crotch band 11A is attached to a coupling member 60 other than the 1 st coupling member 60A located at the forefront of the plurality of coupling members 60. According to this specific example, the 1 st coupling member 60A is disposed at the front of the crotch belt 11A. The forefront 1 st connecting member 60A can stably support the legs of the infant on the seat 70. In particular, according to the 1 st connecting member 60A having flexibility, the leg portion can be gently supported. Further, the abutment of the front frame member 55 with the leg portion can be stably avoided. This can greatly improve the riding comfort of the stroller 10. The crotch belt 11A can be stably held by the connecting member 60.

Further, according to the present embodiment, the seat back 72 includes the accommodation portion RP that accommodates the back support 44, and the accommodation portion RP is opened downward. Therefore, by preventing the size of the accommodating portion RP from becoming excessively large relative to the size of the back support 44 in advance, the seat back 72 can be stably held by the back support 44. Therefore, even if the back support 44 has a frame structure that does not have a conventional base, i.e., a simple three-frame structure, the seat back 72 can be stably maintained on the back support 44. In addition, even if an infant sitting on the stroller 10 leans against the seat back 72, the seat back 72 can be effectively prevented from being greatly deflected at the central portion thereof. That is, even if the back support 44 has a frame structure such as a simple three-sided frame, the infant on the seat 70 can be stably supported. This can greatly reduce the amount of cloth that cannot be removed from the stroller 10 and washed, and can greatly improve the sanitary level of the stroller.

In the illustrated stroller 10, the seat 70 is mounted on the sheet-like member 65 held by the coupling member 60. The sheet-like member 65 is made of resin, has excellent stain resistance as compared with cloth products, and can be sufficiently cleaned by wiping or the like while being kept attached to the stroller body 15.

The cleaned and cleaned seat 70 is again attached to the main body frame 20. First, the back support 44 is inserted from the upper edge thereof into an opening that opens downward of the housing portion RP, and the back support 44 is disposed in the housing portion RP. Next, the 1 st to 4 th mounting mechanisms 75a to 75d are used to mount the seat portion 71 to the seat support 42 and the seat side portion 73 to the main body frame 20. In this way, the seat 70 can be mounted to the stroller body 15 extremely easily.

In one embodiment described above, the seat support assembly 40 for the support seat 70 of the stroller 10 has a seat support body 42 opposite the buttocks of an infant. The seat support 42 includes a pair of side frame elements 50 arranged so as to be separated from each other in the width direction, and a coupling member 60 that extends in the width direction and is provided to bridge the pair of side frame elements 50.

According to the present embodiment, the seat 70 is supported from below by the coupling members 60 that extend in the width direction and are provided to the pair of side frame elements 50. The infant on the seat 70 can be stably supported even if the coupling member 60 is not provided in the entire region between the pair of side frame members 50. This reduces the amount of cloth that cannot be removed from the stroller 10 and washed. Thus, the hygiene level of the stroller 10 can be improved.

In the conventional stroller, the three frames constituting the seat support body are made of metal pipes. In the conventional stroller, the metal tube is in contact with the leg portion such as the thigh of the infant, and thus the riding comfort of the stroller is deteriorated. On the other hand, in the present embodiment, the coupling member 60 supporting the seat 70 from below is supported by the pair of side frame elements 50, and the legs of the infant can be supported by the coupling member 60. Therefore, the front frame member 55 can be arranged at a position lower than the connecting member 60, and the front frame member 55 can be prevented from abutting the legs of the infant. As a result, the riding comfort of the stroller can be improved.

In addition, in one embodiment described above, the stroller 10 has a main body frame 20, a seat support assembly 40 supported by the main body frame 20, and a seat 70 supported by the seat support assembly 40. The seat support assembly 40 includes a seat support 42 facing the buttocks of the infant and a back support 44 swingable with respect to the seat support 42. The seat 70 includes a seat portion 71 supported by the seat support 42, and a seat back 72 connected to the seat portion 71. The seat back 72 includes a housing portion RP that opens downward to house the back support 44.

According to the present embodiment, the seat back 72 can be stably held on the back support 44 even in a frame structure such as a three-frame structure which is a structure without a conventional base. Therefore, the infant on the seat 70 can be stably supported. This can greatly reduce the amount of cloth that cannot be removed from the stroller 10 and washed, and can improve the sanitary level of the stroller 10.

Although an embodiment has been described with reference to specific examples, the specific examples are not intended to limit the embodiment. The above-described embodiment can be implemented in various other specific examples, and various omissions, substitutions, changes, additions, and the like can be made without departing from the spirit thereof.

An example of the modification will be described below with reference to the drawings. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding parts in the above-described specific examples are used for the parts configured similarly to the above-described specific examples, and overlapping descriptions are omitted.

In the above specific example, the seat support assembly 40 has the resin sheet-like member 65 supported by the coupling member 60. However, by appropriately adjusting the number, positions, and widths W of the coupling members 60, the seat 70 can be stably supported. Thus, the sheet-like member 65 may also be omitted from the seat support assembly 40.

In the specific example described above, the 2 nd link L2 is constituted by a part of the grip 30. However, as shown in fig. 11, the main body frame 20 may further have a grip 30 rotatably connected to the 2 nd link L2. When the grip 30 is disposed at the back pushing position, the operator (guardian) grips the grip 30 from the back side of the infant to operate the stroller 10. At this time, the infant can enjoy the scenery in the forward direction of the traveling direction while the stroller 10 is traveling.
