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

As shown in FIG. 2, the side frame element 50 constitutes the fourth link L4 as described above. The pair of side frame elements 50 are arranged apart from each other 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 intermediate portion of the front leg 21 at its front end portion. Further, the side frame element 50 is rotatably connected to the lower end portion of the second link L2 and the upper end portion of the third link L3 at the rear end portion.

As shown in FIG. 4, the side frame element 50 is fixed to the side frame material 51 extending in the front-rear direction, the front end member 52 fixed to the front end portion of the side frame material 51, and the rear end portion of the side frame material 51. It has a rear end member 53 and the rear end member 53. The side frame material 51 may be constructed by using a metal pipe such as an aluminum alloy. The front end member 52 and the rear end member 53 may be configured by using, for example, a resin molded product. As is well shown in FIG. 4, the front end member 52 is provided with a bearing hole 52a through which a shaft (not shown) for rotatably connecting the side frame element 50 and the front leg 21 passes. ing. Further, the front end member 52 is provided with a through hole 52b through which the connecting 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 member 60 is hung on a pair of side frame elements 50. The connecting member 60 is stretched between the pair of side frame elements 50 to support the seat 70 and the infant from below. The connecting member 60 preferably has flexibility, and may further have elasticity. According to such a connecting member 60, the baby can be gently supported and the riding comfort of the baby carriage 10 can be improved.

As shown in FIG. 5, the connecting member 60 is an elongated member extending in the width direction. The width W of the connecting member 60 along the front-rear direction is very short with respect to the length L of the side frame element 50 along the front-rear direction. In the illustrated example, the connecting member 60 is configured as a belt-shaped member. However, the present invention 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 a string. As the connecting member 60, a cloth belt or a cloth string made by sewing cloth, a belt-shaped member or a string-shaped member made of natural leather or synthetic leather, a belt-shaped member or a string-shaped member made of resin, or the like can be used. ..

A plurality of connecting members 60 may be hung on a pair of side frame elements 50 apart from each other in the front-rear direction. As is well shown in FIG. 5, in the illustrated seat support unit 40, the three connecting members 60 are spaced apart from each other in the front-rear direction and hung on a pair of side frame elements 50. However, the present invention is not limited to the illustrated example, and two connecting members 60 may be hung between the pair of side frame elements 50, or four or more connecting members 60 may be hung. When a plurality of connecting members 60 are used, the physical properties and the configuration may be changed according to the arrangement of each connecting member 60. For example, the strength of the connecting member 60 located at the rearmost position in the front-rear direction may be higher than the strength of the other connecting members 60. The width W of the connecting member 60 located at the rearmost position in the front-rear direction may be wider than the width of the other connecting members 60. Further, the elongation rate of the connecting member 60 located at the frontmost position in the front-rear direction may be larger than the elongation rate of the other connecting members 60.

The ratio of the length in which the connecting member 60 is arranged (occupied) in the front-rear direction to the length L of the side frame element 50 in the front-rear direction may be 50% or less, and further 30% or less. May be. The "length in which the connecting members 60 are arranged in the front-rear direction" is the total width W of the plurality of connecting members 60 along the front-rear direction when the plurality of connecting members 60 are provided. When this ratio is small, the reduction of the materials used is preferable not only in terms of manufacturing cost but also in terms of hygiene. Since the connecting member 60 should be maintained in a stretched state, it is assumed that the connecting member 60 cannot be removed from the side frame element 50. Cleaning and cleaning of the non-removable connecting member 60 is troublesome and difficult. Therefore, it is preferable to shorten the length in which the connecting member 60 is arranged in the front-rear direction as much as possible.

From this point, it is preferable that the plurality of connecting members 60 are separated from each other in the front-rear direction and hung on the pair of side frame elements 50. According to this specific example, the infants on the seat 70 can be efficiently and stably supported by the plurality of connecting members 60 dispersedly arranged in the front-rear direction. That is, the amount of the connecting member 60 can be reduced while making it possible to stably support the infant. Therefore, the hygiene aspect of the baby carriage can be further improved.

By the way, as shown in FIG. 1, the baby carriage 10 has a seat belt 11 for fixing the baby to the seat 70. The seat belt 11 includes a crotch belt 11A that passes through the crotch of an infant, a waist belt 11B that passes through the waist of the infant and is detachable from the crotch belt 11A, and a shoulder belt 11A that passes through the shoulder of the infant and is detachable from the crotch belt 11A. It has a belt 11C and. As is well shown in FIGS. 4 and 7, in the illustrated seat support 42, the crotch belt 11A is attached to one connecting member 60. Specifically, a tubular portion is formed at the base end portion of the crotch belt 11A by, for example, sewing, and the connecting member 60 passes through the tubular portion of the crotch belt 11A.

From the viewpoint that the seat belt 11 functions effectively, the crotch belt 11A preferably extends from a position of the seat portion slightly anterior to the center in the anteroposterior 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 forward of the center in the front-rear direction of the seat portion. As a result, in the illustrated example, the crotch belt 11A is attached to a connecting member other than the first connecting member 60A located at the frontmost position in the front-rear direction and the third connecting member 60C located at the rearmost position 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 functioned.

As shown in FIG. 5, the seat support 42 has a first connecting member 60A located in front of the second connecting member 60B to which the crotch belt 11A is attached in the front-rear direction. The frontmost first connecting member 60A can stably support the legs of the baby on the seat 70. According to the first connecting member 60A having particularly flexibility, the legs can be gently supported and the riding comfort of the baby carriage 10 can be improved.

Further, as shown in FIG. 5, the seat support 42 has a third connecting member 60C located at the rearmost position behind the second connecting member 60B to which the crotch belt 11A is attached in the front-rear direction. There is. The seating surface of a normal baby carriage is located behind the extension position of the crotch belt and mainly receives the weight of the baby. Therefore, the third connecting member 60C can stably support the infant. In particular, according to the high-strength third connecting member 60C, the stability of the support of the infant can be increased and the riding comfort of the baby carriage 10 can be improved.

As shown in FIG. 6, the connecting member 60 is attached to the corresponding side frame element 50 at both ends thereof. Each connecting member 60 extends above, outward and downward in the width direction of the corresponding lateral frame element 50 in order at its end and is attached to the inner surface of the lateral frame element 50 in the width direction. There is. In other words, one end of the connecting member 60 is attached to the inner surface of the side frame element 50 (side frame material 51) in the width direction, and then the lower side of the side frame element 50 (side frame material 51) in the vertical direction. Face, the widthwise outer surface of the side frame element 50 (side frame material 51), the vertical upper surface of the side frame element 50 (side frame material 51), and further inward in the width direction. It extends to. According to this embodiment, 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 secured to be long, the infant can be gently supported, and for example, the impact from the traveling surface of the baby carriage 10 can be efficiently absorbed. Further, since the connecting member 60 is attached from the inside in the width direction of the side frame element 50, the attachment portion is not conspicuous, and the aesthetic appearance of the baby carriage 10 can be improved.

In the example shown in FIG. 6, the connecting member 60 is non-detachably fixed to the side frame element 50 by using a fixing tool 63 such as a rivet. As shown in FIG. 5, the second connecting member 60B and the third connecting member 60C revolve around the side frame material 51 of the side frame element 50 and are attached to the side frame material 51. That is, the second connecting member 60B and the third connecting member 60C extend in order from the upper side, the outer side in the width direction, and the lower side of the side frame material 51 of the side frame element 50 on the corresponding side at the end portions, and the side thereof. It is attached to the inner surface of the frame material 51 in the width direction.

As shown in FIGS. 5 and 7, the first connecting member 60A is attached to the front end member 52. However, at the position where the first connecting member 60A is attached, the side frame member 51 exists in the front end member 52. Further, a through hole 52b is provided at a position below the side frame member 51 in the front end member 52. The first connecting member 60A passes through the through hole 52b and extends from the outside in the width direction to the inside in the width direction of the side frame element 50. By using the through hole 52b, the first connecting member 60A can be stably mounted on the front end member 52 having a complicated shape.

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

As described above, according to the seat support 42 provided with the resin sheet-shaped member 65 supported by the connecting member 60, the connecting member 60 has a wide area on the seat 70 through the sheet-shaped member 65. Will support. Therefore, the infant is stably supported by the sheet-like member 65 and the connecting member 60 having a certain degree of flexibility with a more uniform force. Further, since the connecting member 60 supports the infant via the sheet-shaped member 65, the quantity of the connecting member 60 and the width W in the front-rear direction can be reduced, and the amount of the connecting member 60 can be reduced. The resin sheet-like member 65 is superior in antifouling property as compared with cloth or the like, and can be sufficiently washed and cleaned while being attached to the baby carriage 10. For example, the resin sheet-like member 65 can be easily cleaned by wiping with dry cloth or water. That is, by installing the sheet-shaped member 65, it is possible to stably support the infant and improve the riding comfort, while further improving the hygiene aspect of the baby carriage.

As shown in FIG. 5, the length of the sheet-shaped member 65 along the front-rear direction is substantially the same as the length of the side frame element 50 along the front-rear direction. Similarly, the length of the sheet-like member 65 along the width direction is substantially the same as the distance along the width direction between the outer surfaces of the pair of side frame elements 50 in the width direction. That is, the illustrated sheet-shaped member 65 extends over substantially the entire area of the seat support 42 when viewed from above.

Preferably, the pair of side frame elements 50 are positioned so as to at least partially overlap the sheet-like member 65 in the top view shown in FIG. According to this configuration, the sheet-like member 65 is supported from below by a pair of side frame elements 50. Therefore, it is possible to prevent the sheet-shaped member 65 from bending so that the outer portion in the width direction hangs down. As a result, the baby can be supported more stably via the sheet-shaped member 65. Further, since the support state by the sheet-shaped member 65 is stable, the number of the connecting members 60 and the width W in the front-rear direction can be reduced, and the area of the connecting members 60 can be reduced.

In the illustrated example, the sheet-shaped member 65 is provided with a hole 65a through which the connecting member 60 passes. As the connecting member 60 passes through the hole 65a of the sheet-shaped member 65, the sheet-shaped member 65 is held by the connecting member 60. According to such a holding method, the sheet-like member 65 can move somewhat relative to the connecting member 60. By such play, the impact from the road surface and the like can be absorbed, and the riding comfort of the baby carriage 10 can be improved.

In particular, as shown in FIGS. 5 and 6, the sheet-shaped member 65 is provided with four holes 65a through which one connecting member 60 passes. In the illustrated example, the three connecting members 60 are arranged 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-shaped member 65. Each connecting member 60 supports the sheet-shaped member 65 from below at both end portions and a central portion in the longitudinal direction thereof. According to this configuration, since the sheet-shaped member 65 is supported from below by the connecting member 60, it is possible to prevent it from hanging down in the outer portion in the width direction and denting downward in the central portion in the width direction. As a result, the connecting member 60 can more stably support the infant via the sheet-shaped member 65. Further, since the support state by the sheet-shaped member 65 is stable, the number of the connecting members 60 and the width W in the front-rear direction can be reduced, and the area of the connecting members 60 can be reduced.

As described above, the crotch belt 11A is attached to the second connecting member 60B. The crotch belt 11A is located at the center in the width direction. A belt hole 65b is provided at a position of the sheet-shaped member 65 facing the crotch belt 11A. The crotch belt 11A passes through the belt hole 65b and extends from the lower side to the upper side of the sheet-shaped member 65.

As shown only in FIG. 6, the end face of the sheet-shaped member 65 may be chased by the covering material 67. The covering material 67 may be provided so as to cover any one or more of the side end surface, the front end surface, and the rear end surface of the sheet-shaped member 65, or may be provided so as to cover the end face over the entire circumference of the sheet-shaped member 65. You may. The dressing 67 may be constructed of cloth, for example. By providing the covering material 67, the aesthetic appearance can be improved and the handleability is excellent.

By the way, as is well shown in FIG. 7, the seat support 42 further has a front frame member 55 and an intermediate frame member 57 as members extending in the width direction. The front frame material 55 and the intermediate frame material 57 may be constructed by using, for example, a metal pipe such as an aluminum alloy or a resin molded product. Such a front frame material 55 and an intermediate frame material 57 are located between a pair of side frame elements 50, and maintain a constant or longer separation interval in the width direction of the pair of side frame elements 50. As a result, the connecting member 60 can be maintained in a stretched state, and the infant can be supported more stably.

As shown in FIG. 7, the front frame material 55 and the intermediate frame material 57 are located below any of the side frame element 50, the connecting member 60, and the seat 70 in the vertical direction. As shown in FIG. 5, the front frame member 55 is located behind the front end of the side frame element 50 in the front-rear direction. The front frame member 55 is located behind the front end of the side frame member 51 in the front-rear direction. The front frame member 55 is located behind the front end of the first connecting member 60A in the front-rear direction. The front frame member 55 is located behind the front end of the sheet-shaped member 65 in the front-rear direction. The front frame material 55 arranged at such a position is less likely to come into contact with the legs of the baby riding on the baby carriage 10.

Next, the operation of the baby carriage 10 having the above configuration when used will be described.

With the baby sitting or lying down on the seat 70 of the baby carriage 10, the user grips the handle 30 and runs the baby carriage 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. Further, by using the first to fourth mounting means 75a to 75d, the seat 70 can be stably held by the seat support unit 40 and the main body frame 20. As a result, it is possible to provide an excellent ride quality to the infant without causing the infant on the seat 70 to feel excessive shaking or vibration.

By the way, in the conventional baby carriage, as a seat support for supporting the seat seat of the seat, for example, a three-sided frame made by bending a metal pipe has been used. In such a conventional baby carriage, the seat support formed by the three-sided frame supports the seat from below by a frame material having rigidity extending in the width direction. Therefore, no matter how much the seat has cushioning properties, the infant could sense that the frame material extending in the width direction hits the legs. When the frame material hits the legs of the thighs of infants in this way, the riding comfort of the baby carriage is deteriorated.

On the other hand, in the seat support unit 40 of the baby carriage 10 according to the present embodiment, the connecting member 60 that supports the seat 70 from below is supported by a pair of side frame elements 50. The connecting member 60 is made of, for example, a cloth, a comparison, a resin, or the like, and is more flexible than the side frame element 50 and more easily deformed than the side frame element 50. Since the connecting member 60 is provided, it is not necessary to install the front frame material 55 at the same position as the conventional baby carriage, that is, at the same height as the side frame element 50. Therefore, it is possible to prevent the highly rigid frame material from hitting the legs of the baby, and it is possible to improve the riding comfort.

In the illustrated example, as shown in FIG. 5, the first 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 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 that covers the side frame member 51 in the front-rear direction. According to this specific example, the first connecting member 60A is arranged forward, and the legs of the infant can be gently and stably supported from below by using the first connecting member 60A. Further, when the first connecting member 60A is fixed to the side frame element 50 by using a fixing tool such as a rivet, the front end member 52 can be fixed together with the front end portion of the side frame material 51.

Further, in the illustrated example, the seat support 42 has a front frame material 55 that connects a 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 high-rigidity front frame material 55, it is possible to maintain the distance between the pair of side frame elements 50 in the width direction. As a result, the connecting member 60 can be maintained in a stretched state, and the infant can be supported more stably via the sheet 70. Since the front frame material 55 is located behind the front end of the frontmost first connecting member 60A, it is possible to prevent the front frame material 55 from hitting the legs of the baby and to improve the riding comfort of the baby carriage 10. Can be improved.

Similarly, in the illustrated example, the front frame material 55 is located below the side frame material 51 of the side frame element 50 and behind the front end of the side frame element 50. The front frame member 55 is located below the sheet-shaped member 65 and behind the front end of the sheet-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 sheet-shaped member 65 supported by the connecting member 60. As a result, the front frame material 55 is located in the region of the sheet 70 that overlaps with the side frame element 50 in the front-rear direction, and is vertically separated from the portion supported by the side frame element 50 from below. Therefore, it is possible to prevent the front frame material 55 from hitting the legs of the baby and improve the riding comfort of the baby carriage.

Further, it is assumed that the seat 70 becomes dirty with the use of the baby carriage 10. In this case, the seat 70 can be removed from the baby carriage body 15 to clean and clean the seat 70. Specifically, first, by releasing the first to fourth mounting means 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 44 of the seat support unit 40 is taken out from the accommodating portion RP of the seat back 72. As described above, the seat 70 can be removed from the baby carriage body 15 very easily.

Here, in the conventional baby carriage, as already explained as a background technique, it was not possible to remove the base sheet as a cloth product spread over a wide area from the baby carriage body and wash it. This base sheet was widely stretched over a three-sided frame forming a seat support and a three-sided frame forming a back support.

On the other hand, according to the present embodiment, the seat 70 is supported from below by the elongated connecting member 60 that is hung on 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, the infant on the seat 70 can be stably supported. In the conventional baby carriage, the base seat spreads over almost the entire area of the three-sided frame in the front-rear direction. On the other hand, according to the present embodiment, the connecting member 60 in the front-rear direction is arranged (occupied) with respect to the length L (see FIG. 5) of the side frame element 50 in the front-rear direction. The ratio of the above can be 50% or less, and further can be 30% or less.
