Description

baby carriage

One aspect of the present disclosure relates to a baby carriage.

Conventionally, a baby carriage is known that includes a baby carriage body and a seat supported by the baby carriage body (for example, Patent Document 1). In the baby carriage described in Patent Document 1, the seat is configured to be removable from the baby carriage body. In a stroller with a removable seat as described above, in order to fix the seat to the stroller body, a large number of fixing devices such as hook belts provided on each of the seat surface and backrest of the seat are attached to the stroller body (frame). A mechanism is generally used to fix the

JP2013-241138A

The above-mentioned mechanism for fixing the seat to the baby carriage body using a large number of hook belts is time-consuming because it is necessary to attach and detach all the hook belts when attaching and detaching the seat. Further, if the hook belts are provided at multiple locations, it becomes difficult for the user to accurately grasp and memorize the attachment position of each hook belt with respect to the baby carriage body when attaching the seat.

One aspect of the present disclosure aims to provide a baby carriage that can improve the convenience of attaching and detaching a seat.

A baby carriage according to one aspect of the present disclosure includes a baby carriage main body having a seat support part, a seat supported by the seat support part, and the seat includes a seat part, a backrest part connected to the seat part, The seat support part has a seat support part that supports the seat part and a back support part that supports the back part, and the seat part is provided on a surface facing the seat support part. the back support part has a second surface fastener part including one or more hook and loop fasteners provided on a surface facing the back support part; , the seat support part has a third hook-and-loop fastener part including one or more hook-and-loop fasteners provided at a position corresponding to the first hook-and-loop fastener part, and the back support part corresponds to the second hook-and-loop fastener part. The fourth hook-and-loop fastener part includes one or more hook-and-loop fasteners provided at the positions.

In the baby carriage according to one aspect of the present disclosure, the seat surface portion of the seat is fixed to the seat surface support portion of the seat support portion via the first hook-and-loop fastener portion and the third hook-and-loop fastener portion, and the seat back portion of the seat is fixed to the seat support portion of the seat support portion. is fixed to the back support portion of the seat support portion via the second surface fastener portion and the fourth surface fastener portion. In this manner, by fixing both the seat surface portion and the backrest portion of the seat to the seat support portion using the hook-and-loop fastener, the seat can be stably fixed to the seat support portion in a well-balanced manner. Furthermore, since the number of fixing devices such as hook belts that have been commonly used in the past can be reduced, the sheet removal operation can be simplified. Furthermore, the user can fix the seat to the seat support by simply pressing the seat and backrest of the seat against the corresponding positions on the seat support, and the user can simply pull the seat away from the seat support. The seat can be removed from the seat support. Therefore, according to the above baby carriage, it is possible to improve the convenience of attaching and detaching the seat.

One or more hook-and-loop fasteners included in the first hook-and-loop fastener part may be formed in a shape with a length in the left-right direction longer than the length in the front-back direction, and one or more hook-and-loop fasteners included in the third hook-and-loop fastener part , may have a shape corresponding to one or more hook-and-loop fasteners included in the first hook-and-loop fastener section. Usually, the frame of the baby carriage body is arranged on both sides of the seat support part of the seat support part in the left-right direction. On the other hand, such a frame as described above is not arranged in front of the seat support portion. Therefore, when the seat part of the seat is fixed (placed) on the seat support part, there is little risk of the position of the seat part relative to the seat support part shifting in the left-right direction, while the position of the seat part relative to the seat support part is The position may shift in the front-back direction. If the hook-and-loop fastener included in the first hook-and-loop fastener portion or the hook-and-loop fastener included in the third hook-and-loop fastener portion is formed in a shape that is longer in the front-rear direction than in the left-right direction, Even if the position of the seat portion of the seat is slightly shifted in the front-rear direction, the first hook-and-loop fastener portion and the third hook-and-loop fastener portion come into contact and are fixed to each other. In contrast, by forming the hook-and-loop fasteners included in the first hook-and-loop fastener part and the third hook-and-loop fastener part in a shape that has a longer length in the left-right direction than in the front-back direction, When the surface portions are shifted in the front-rear direction, the first surface fastener portion and the third surface fastener portion become difficult to come into contact with each other. As a result, it is possible to prevent the seat portion from being fixed to the seat support portion in a state shifted in the front-rear direction with respect to the seat support portion.

The seat may have a connecting member provided near the boundary where the seat portion and the backrest are connected, and the baby carriage body may have a frame member that is connected to the connecting member. . According to the above configuration, the connecting member can fix the seat to the seat support portion and align the boundary between the seat surface portion and the backrest portion of the seat at an appropriate position. This makes it possible to easily fix the seat portion at an appropriate position relative to the seat support portion, for example, by swinging the seat portion using the boundary portion as the pivot axis and pressing the seat portion against the seat support portion. can. Similarly, by swinging the back rest using the boundary as the swing axis and pressing it against the back support support, the back rest can be easily fixed at an appropriate position relative to the back support support. can.

The second surface fastener section may include a plurality of surface fasteners, and the fourth surface fastener section may include a plurality of surface fasteners corresponding to the plurality of surface fasteners included in the second surface fastener section. According to the above configuration, the area of each hook-and-loop fastener required for fixing the back rest to the back support with sufficient strength can be reduced. As a result, it is possible to avoid obstructing the air permeability of a specific part of the backrest due to the provision of a large hook-and-loop fastener, and thus it is possible to maintain the comfort of the infant riding in the baby carriage.

The second hook-and-loop fastener part may be provided at a position along the edge of the backrest part. According to the above configuration, by not providing a hook-and-loop fastener in the area that overlaps with the central part of the backrest, it is possible to ensure ventilation in the part of the backrest that is mainly in contact with the baby's back. It is possible to maintain the comfort of the infant riding on the vehicle.

The second hook-and-loop fastener portion may include a hook-and-loop fastener provided at least along the edge of the backrest portion on the side opposite to the side connected to the seat surface portion. According to the above configuration, by fixing the backrest to the backrest support at a position as far away from the seat surface as possible, the backrest can be stably supported with respect to the backrest support.

The seat support part may have a support frame formed along a second part of the edge of the backrest part other than the first part connected to the seat part, and the second part of the backrest part may be provided with a suppressing member that suppresses deformation of the edge. According to the above configuration, the back rest can be easily moved against the back support by pressing the back rest against the back support so that the second portion of the edge of the back rest is along the support frame. In addition, proper positioning can be achieved. Further, since the deformation of the second portion is suppressed by the suppressing member provided on the second portion, the above-mentioned operation can be easily performed, and the support stability of the backrest portion can be improved.

The suppressing member may be a covering member that pipes the second portion. According to the above configuration, the suppressing member can be easily and reliably provided by the covering member piping the second portion. In addition, since piping improves the visibility and appearance of the part where the backrest is placed along the support frame, the user can use the piping (covering member) as a mark to help the user place the backrest against the seat supporter. It becomes possible to easily arrange the parts at appropriate positions.

According to one aspect of the present disclosure, it is possible to provide a baby carriage that can improve the convenience of attaching and detaching the seat.

That is, the baby carriage 1 is configured to be switchable between the unfolded state shown in FIGS. 1 to 3 and the folded state shown in FIG. 4. The unfolded state is a state in which the stroller body 2 is spread out (expanded) so that an infant can ride in the stroller 1. The folded state is a state in which the baby carriage body 2 is folded in order to store the baby carriage 1 compactly.

In this specification, the terms "front", "rear", "left", "right", "top", "bottom", "front-back direction", "left-right direction", and "up-down direction" with respect to the baby carriage 1 are used. Unless otherwise specified, "front", "rear", "left", "right", "top", "bottom", "back and forth direction", based on the infant riding in the stroller 1 in the unfolded state, Means "left-right direction" and "up-down direction". When the ground plane of the baby carriage 1 is a horizontal plane, the "back and forth direction" is a direction in which the baby carriage 1 moves forward and backward parallel to the ground plane. Moreover, the "vertical direction" is a direction that is perpendicular to the front-rear direction and perpendicular to the ground plane. Moreover, the "left-right direction" is a direction perpendicular to both the front-back direction and the up-down direction.

In FIGS. 1 to 4, the "front-back direction" is expressed as the X-axis direction, the "left-right direction" is expressed as the Y-axis direction, and the "up-down direction" is expressed as the Z-axis direction. The negative side in the X-axis direction corresponds to the "front", and the positive side in the X-axis direction corresponds to the "rear". Further, the positive direction in the Y-axis direction corresponds to "right", and the negative direction in the Y-axis direction corresponds to "left". Further, the positive direction in the Z-axis direction corresponds to "up", and the negative direction in the Z-axis direction corresponds to "down". In addition, in the "left-right direction", the side that approaches the infant riding in the baby carriage 1 (the center of the baby carriage 1 in the left-right direction) is referred to as the inside, and the side that is separated from the infant is referred to as the outside.

As shown in FIGS. 1 and 2, the baby carriage 1 includes a baby carriage body 2 and a seat 3 attached to the baby carriage body 2. The baby carriage body 2 includes a body frame 10, a handle 20 and a seat support portion 30 connected to the body frame 10. 1 and 2 are perspective views showing the baby carriage 1 in the unfolded state.

The upper end of each front leg 11 is rotatably connected to the front end of an armrest 13 disposed on the side corresponding to each front leg 11 (left side or right side). Similarly, the upper end of each rear leg 12 is rotatably connected to the front end of an armrest 13 disposed on the side corresponding to each rear leg 12 (left side or right side). The rear end portion of each armrest 13 is connected via a link member 14 and a rotation bracket 15 to an intermediate portion of a rear leg 12 disposed on the side corresponding to each armrest 13 (left side or right side). A projection 14a is provided at the upper end of the link member 14 for connecting a connecting member 101 provided on a side wall 80, which will be described later. The protrusion 14a is formed into a pin shape that extends upward in parallel with the link member 14.

The handle 20 is swingably connected to the main body frame 10 configured as described above. As shown in FIGS. 1 and 2, the handle 20 is formed in a U-shape. In the rear pushing state shown in FIGS. 1 to 3 (i.e., the state in which the operator (guardian) grips the handle 20 from the back side of the infant riding in the stroller 1 and operates the stroller 1), both ends of the handle 20 Each part is connected to the link member 14 on the side corresponding to each part (left side or right side) so that the state parallel to the link member 14 is maintained. Note that the handle 20 may be configured to be able to swing counterclockwise in FIG. 3 with respect to the main body frame 10 so that the handle portion of the handle 20 moves in front of the infant riding in the baby carriage 1. . In this case, the operator can operate the baby carriage by grasping the handle 20 from a position on the side of the front legs 11 facing the infant. That is, it is possible to run the baby carriage 1 with the rear leg 12 side of the baby carriage 1 facing forward in the traveling direction. In such a facing state, the handle 20 becomes non-parallel to the link member 14. An operating section 20a is provided at the center of the handle 20 for performing an operation for switching between the unfolded state and the folded state. By operating the operating unit 20a, it is possible to switch between a locked state in which the unfolded state or the folded state is maintained, and an unlocked state in which the unfolded state and the folded state can be switched.

The baby carriage 1 can be folded from the unfolded state (see FIGS. 1 to 3) to the folded state (see FIG. 4) by rotating each component relative to each other as follows.

In this embodiment, as an example, when folding the baby stroller 1 in the unfolded state shown in FIGS. 1 to 3, the handle 20 is first pulled upward while operating the operating part 20a to be in the unlocked state, and then the handle 20 is pulled downward.

Furthermore, the number of fixing devices such as hook belts that have been commonly used in the past for attaching the seat to the baby carriage main body 2 (for example, a fixing device similar to the above-mentioned connecting member 101) can be reduced. For example, conventionally, a mechanism has generally been adopted in which at least one pair of hook belts (one pair on the left and right) is provided on each of the seat portion 40 and the backrest portion 50, and the hook belts are attached to the base seat 33. In the baby carriage 1, by providing the first hook-and-loop fastener section 91, the second hook-and-loop fastener section 92, the third hook-and-loop fastener section 93, and the fourth hook-and-loop fastener section 94, the seat surface section 40 and the backrest section 50 can be fixed as described above. The hook belt that was conventionally provided in each is omitted. This makes it possible to reduce the cost of the baby carriage 1 by reducing the number of parts, and to simplify the operation of attaching and detaching the seat 3. Further, the user can fix the seat 3 to the seat support section 30 by simply pressing the seat surface section 40 and the backrest section 50 of the seat 3 against the corresponding positions of the seat support section 30, The seat 3 can be removed from the seat support section 30 by simply pulling it away from the seat support section 30. That is, by using a hook-and-loop fastener as a main member for attaching the seat 3 to the seat support section 30, the seat 3 can be attached to and removed from the seat support section 30 intuitively and easily. Therefore, according to the baby carriage 1, the convenience of attaching and detaching the seat 3 can be improved.

One or more hook-and-loop fasteners (in this embodiment, hook-and-loop fasteners 911) included in the first hook-and-loop fastener portion 91 have a shape that is longer in the left-right direction (Y-axis direction) than in the front-back direction (X-axis direction). (In this embodiment, it is formed in a rectangular shape as an example). Furthermore, one or more hook-and-loop fasteners (in this embodiment, hook-and-loop fasteners 931) included in the third hook-and-loop fastener section 93 are different from one or more hook-and-loop fasteners (in this embodiment, hook-and-loop fasteners) included in the first hook-and-loop fastener section 91. 911). As in the present embodiment, frames (for example, armrests 13, etc.) of the baby carriage main body 2 are usually arranged on both sides of the seat support part 331 of the seat support part 30 in the left-right direction (Y-axis direction). On the other hand, as shown in FIG. 2, such a frame as described above is not arranged in front of the seat support portion 331. Therefore, when fixing (placing) the seat part 40 of the seat 3 on the seat support part 331, there is little risk that the position of the seat part 40 with respect to the seat support part 331 will shift in the left-right direction (Y-axis direction). Therefore, the position of the seat portion 40 relative to the seat support portion 331 may shift in the front-rear direction (X-axis direction). Suppose that the length of the hook-and-loop fastener 911 included in the first hook-and-loop fastener portion 91 or the hook-and-loop fastener 931 included in the third hook-and-loop fastener portion 93 is longer in the front-rear direction (X-axis direction) than in the left-right direction (Y-axis direction). If it is formed into a long shape, even if the position of the seat portion 40 of the seat 3 relative to the seat support portion 331 is slightly shifted in the front-rear direction (X-axis direction), the first hook-and-loop fastener portion 91 (loop-and-loop fastener 911) The third hook-and-loop fastener portion 93 (the hook-and-loop fastener 931) comes into contact and becomes fixed to each other. On the other hand, the length of the hook-and-

loop fasteners

911 and 931 included in the first hook-and-loop fastener section 91 and the third hook-and-loop fastener section 93 in the left-right direction (Y-axis direction) is longer than the length in the front-back direction (X-axis direction). By forming the shape, the first hook-and-loop fastener portion 91 and the third hook-and-loop fastener portion 93 come into contact with each other when the seat portion 40 is displaced in the front-rear direction (X-axis direction) with respect to the seat support portion 331. It becomes difficult to do. As a result, it is possible to prevent the seat portion 40 from being fixed to the seat support portion 331 in a state shifted in the front-rear direction (X-axis direction) with respect to the seat support portion 331.

The seat 3 is located near the boundary (connection line L1) where the seat portion 40 and the backrest 50 are connected (in the present embodiment, near both ends of the connection line L1 in the left-right direction (Y-axis direction)). It has a connecting member 102 (see FIG. 6) provided therein. The baby carriage body 2 also includes a frame member (link member 14 in this embodiment) that is connected to the connecting member 102 . In this embodiment, the connecting member 102 has the same configuration as the connecting member 101. The connecting member 102 is a hook belt having a belt portion 102a fixed to the back surface 4b of the sheet 3, and a pair of hooks 102b provided at both ends of the belt portion 102a. By wrapping the belt portion 102a around the side surface of the link member 14 and fastening the pair of hooks 102b (that is, the concave portion and the convex portion) to each other, the connecting member 102 is attached to the link member 14 as shown in FIG. Fixed. According to the above configuration, the seat 3 is fixed to the seat support part 30 by the connecting member 102, and the boundary part (connection line L1) between the seat surface part 40 and the backrest part 50 of the seat 3 is adjusted to an appropriate position. be able to. Thereby, for example, by swinging the seat part 40 using the boundary as the swing axis and pressing it against the seat support part 331, the seat part 40 can be easily positioned at an appropriate position ( That is, it can be fixed at a position where the hook-and-loop fastener 911 and the hook-and-loop fastener 931 exactly overlap. Similarly, by swinging the back rest 50 using the boundary as the swing axis and pressing it against the back rest support 332, the back rest 50 can be easily positioned at an appropriate position ( In other words, they can be fixed at positions where the hook-and-loop fasteners 921 to 924 and the hook-and-loop fasteners 941 to 944 exactly overlap. In this way, by appropriately aligning the boundary position between the seat surface portion 40 and the backrest portion 50 using the connecting member 102, it becomes possible to easily align the seat surface portion 40 and the backrest portion 50. The convenience of the work of installing the seat 3 can be improved. Further, by using the hook-and-loop fastener and the connecting member 102 in combination, the number of connecting members can be reduced to improve the convenience of the installation work, and the stability of the sheet 3 can be improved. For example, the connecting member 102 prevents the boundary between the seat portion 40 and the backrest portion 50 from shifting in the front-rear direction (X-axis direction) with respect to the seat support portion 30. This prevents the entire seat 3 from moving significantly in the front-rear direction (X-axis direction) due to the movement of an infant seated on the seat 3, etc. It is possible to prevent the fixation from coming off.

The second hook-and-loop fastener section 92 includes a plurality of hook-and-loop fasteners (in this embodiment, four hook-and-loop fasteners 921 to 924). Further, the fourth surface fastener section 94 includes a plurality of surface fasteners 941 to 944 corresponding to the plurality of surface fasteners 921 to 924 included in the second surface fastener section 92. According to the above configuration, it is possible to reduce the area of the individual hook-and-loop fasteners 921 to 924 and 941 to 944 required to fix the back rest part 50 to the back rest support part 332 with sufficient strength. Thereby, it is possible to avoid obstructing the air permeability of a specific part of the backrest part 50 due to the provision of a large hook-and-loop fastener, so that the comfort of the infant riding in the baby carriage 1 can be maintained.

The second hook-and-loop fastener section 92 is provided at a position along the edge 51 of the backrest section 50. Correspondingly, the fourth hook-and-loop fastener section 94 is provided at a position along the edge of the back support section 332. According to the above configuration, by not providing a hook-and-loop fastener in the area that overlaps with the central part of the back rest part 50, it is possible to ensure breathability in the part of the back rest part 50 that is mainly in contact with the infant's back. The comfort of the infant riding in the baby carriage 1 can be maintained. For example, when the back rest 50 is made of a material with good air permeability such as mesh fabric, a gap in the mesh fabric may be closed by a hook-and-loop fastener provided in an area that overlaps the center of the back rest 50. This prevents the ventilation of the area that mainly comes into contact with the infant's back from being obstructed.

The second hook-and-loop fastener portion 92 is a hook-and-loop fastener (in this embodiment, hook-and-loop fasteners 922 and 923) provided along at least the edge 51a of the backrest portion 50 on the side opposite to the side connected to the seat surface portion 40. Contains. According to the above configuration, by fixing the backrest part 50 to the backrest support part 332 at a position as far away from the seat part 40 as possible, the backrest part 50 can be stably supported with respect to the backrest support part 332. I can do it.

The seat support part 30 includes a second part 51c (in FIG. 6, the edge part 51 of the back support part 50) other than the first part 51b (that is, the part along the connection line L1) connected to the seat part 40. It has a support frame (in this embodiment, the back support support frame 32) formed along the inverted U-shaped portion (including the edge 51a) of the portion 51 excluding the first portion 51b. . Further, the second portion 51c of the back support portion 50 is provided with a suppressing member 103 that suppresses deformation of the edge portion 51. According to the above configuration, the back rest 50 is moved by pressing the back rest 50 against the back support support 332 so that the second portion 51c of the edge 51 of the back rest 50 is along the back support frame 32. It can be easily and appropriately aligned with respect to the back support part 332. Further, since the deformation of the second portion 51c is suppressed by the suppressing member 103 provided on the second portion 51c, the above operation can be easily performed and the support stability of the back rest portion 50 is improved. I can do it.

In this embodiment, the suppressing member 103 is formed of a covering member that pipes the second portion 51c. According to the above configuration, the suppressing member 103 can be easily and reliably provided by the covering member (for example, piping tape, etc.) piped along the second portion 51c. In addition, since the piping improves the visibility and appearance of the portion where the back rest 50 is placed along the back support frame 32, the user can move the seat support 30 along the seat support frame 32 by using the piping (covering member) as a landmark. It becomes possible to easily arrange the back rest part 50 at an appropriate position. In addition, in this embodiment, as shown in FIG. 6, the restraining member 103 extends to the edge of the seat part 40 that is continuous with the edge 51 of the backrest part 50, and connects the seat part 40 and the side wall part 80. It is also formed between.

Although one embodiment of the present disclosure has been described above, the present disclosure is not limited to the embodiment described above. The materials and shapes of each structure are not limited to the materials and shapes described above, but various materials and shapes can be employed.

For example, the configuration of the baby carriage main body 2 of the baby carriage 1 of the above embodiment is merely an example, and may have a frame structure different from that of the above embodiment. Further, the seat 3 only needs to have at least the seat portion 40 and the backrest portion 50, and other components (for example, the hood portion 70) may be omitted.
