Description

  The present invention relates to a baby buggy that transports an infant on board, and more particularly relates to a baby buggy that has an improved seat mounting structure for riding an infant.

  In general, this type of baby buggy is constructed by three-dimensionally combining a frame and a folding member, with a handle for pushing at the upper rear end of the frame, a wheel for transfer at the lower end, and A seat on which an infant rides is provided in a space surrounded by the frame and the folding member. Further, when the seat is attached, the both ends of the unfolded sheet are wound around the left and right frames, and the both ends of the wound sheet are fixed.

  However, since both side ends of the seat are wound around the frame and attached, a part of the frame is covered with the seat mounting portion, the appearance around the frame is inferior, and the high-quality feeling of the baby buggy cannot be improved. In addition, the seat winding part is loaded downward, so it is necessary to ensure stable attachment to the frame. However, the sheet wound around the frame is easily displaced in the axial direction of the frame, and it can be misaligned. For example, there is a sense of incongruity in the attachment portion between the rigid frame and the flexible sheet.

  Therefore, as a seat mounting means that does not cause an improvement in aesthetics or a sense of incongruity, there is a small cylindrical groove in the axial direction for mounting the seat in the cylindrical body of the front inclined rod (tubular frame) provided on the left and right sides, A sheet attaching means for attaching a sheet by attaching a long member for attaching the sheet to the sheet in advance and inserting the long member into the cylindrical groove of the frame is known (for example, see Patent Document 1). ).

  However, in this type of seat mounting means, it is necessary to form a long, small cylindrical groove in the axial direction inside the cylinder of the forward inclined rod. For this reason, the structure of the forward inclined ridge is complicated, and it takes time and effort to produce, leading to high costs. In addition, when attaching the seat, a long member has to be inserted from the end face opening of the front inclined rod, and it takes time and trouble to attach the seat.

Therefore, the seat can be easily attached only by locking the locked portion and the locking portion to each other without winding the seat around the front frame. As a result, the seat fits between the left and right front frames, the seat portion is not exposed on the outer surface side of the front frame, and there is no sense of incongruity at the seat mounting portion. For this reason, the beauty can be enhanced and a high-class feeling of baby buggy can be obtained.

  In another configuration of the present invention, the front frame may be configured by a pipe frame having a D-shaped cross section, and may be configured so that the D-shaped plane portion is on the inner side in the width direction.

  According to the present invention, by configuring the front frame with a pipe frame having a D-shaped cross section, the flat portion of the D-type is not a curved surface, so that the mounting surface is suitable for the locking structure, and one of the locking structures is easily formed. . For example, it is possible to easily craft the formation of a hole as a locked portion or the formation of a rotation stopper. Furthermore, by disposing the D-shaped flat portion on the inner side in the width direction of the baby buggy, the flat portion is directed inward in the width direction, and the flat portion is brought into contact with the end of the seat. Suitable for

  According to another attachment means of the present invention, a seat attachment device that engages and locks the locked portion and the engagement portion locally corresponds to each other, and a plurality of pairs of the sheet attachment devices are arranged on a plurality of sides of the seat. It can be set as the structure arrange | positioned corresponding to a location.

  According to the present invention, if a seat mounting device that locally locks from a pair of a locked portion and a locking portion is configured, it is caused to partially correspond between the left and right front frames and one sheet. Can be installed. For example, for a single sheet that is mounted in the unfolded state, a total of four positions on the left and right sides of the sheet are set as the mounting positions of each sheet mounting apparatus, and the sheets are locally positioned at the four positions. Can be supported.

  In another configuration of the present invention, the attachment means may be provided with a detachment preventing means for preventing the locked state of the locked portion and the locking portion from being inadvertently released.

  According to the present invention, when the seat is attached to the front frame, it is possible to prevent the attached locking portion from being inadvertently removed by the disengagement preventing means, so even if some force is applied from the outside. It will not come off carelessly, and safety after seat installation can be improved. This disengagement prevention means is configured by, for example, a structure in which either one of the locking part side or the locked part side is provided as a convex and the other is provided as a concave so as to correspond to the unevenness or a structure that fixes the locking state. be able to.

  In another attachment means of the present invention, the locked portion is configured by a pedestal having an insertion groove that is fixed to the front frame from the inner side in the width direction of the front frame and the insertion direction is set from the upper side to the lower side. In addition, the engaging portion may be configured by a sheet coupling body attached to an end portion of the sheet, and the sheet coupling body may be inserted into the insertion groove of the base and coupled.

  According to the present invention, the seat can be coupled to the front frame by inserting a part or all of the seat coupling body into the insertion groove of the base fixed to the front frame. In this case, since the seat receives a downward load in the use state, the insertion direction of the insertion groove is set from the upper side to the lower side so that the sheet coupling body integrated with the seat does not come off from the base. Further, if the seat coupling body is slid in the direction opposite to the direction in which the seat coupling body is inserted and detached, the seat coupling body is detached from the pedestal, so that the seat can be removed from the front frame.

  In another attachment means of the present invention, the locked portion is configured by a locking hole that opens to the inner side in the width direction of the front frame, and the locking portion is a locking claw provided near the end of the seat. It can comprise, and it can be set as the structure which hooks and attaches the said locking claw to the said locking hole.

  According to the present invention, the seat can be attached to the front frame simply by hooking the locking claw at the end of the seat into the locking hole of the front frame. For this reason, the mounting operation of the sheet becomes easy. In addition, since the locking structure can be constructed simply by opening the locking hole in the front frame and attaching the locking claw locked to the locking hole to the seat, the locking structure can be simplified. Costs can be reduced by reducing the number of parts.

  According to the present invention, the seat has a locking structure that allows the seat to be easily attached by locking the seat from the inner side in the width direction of the front frame arranged on both the left and right sides, and a part of the seat is the front frame. Since it is not exposed to the outside, the beauty of the baby buggy is improved.

An embodiment of the present invention will be described below with reference to the drawings. The drawings show a seat attachment device provided in a baby buggy, FIG. 1 is an external perspective view of the baby buggy, and FIG. 2 is a development view of the seat provided in the baby buggy.
The baby buggy 11 is inclined in parallel from the front lower part to the rear upper part substantially parallel to the left and right sides in the width direction, and has a front frame 12 having a folding hinge 12a that is folded in half at a substantially central part thereof, and the front frame A rear frame 13 which is pivotably attached to the rear upper part of the frame 12 and extends to the lower part of the rear part, and a foldable link piece 14 having a link structure which is foldably connected between the frames 12 and 13 vertically and horizontally. The wheels 15 are attached to the lower ends of the front and rear frames 12 and 13 on both sides, and a seat 16 on which an infant rides is attached to a space surrounded by the frames 12 and 13 and the folding link piece 14. In addition, a handle 17 for pushing and a sun hood 18 are provided at the upper rear end of the front frame 12.

Further, the baby buggy 11 includes a seat attachment device 19 that facilitates the attachment of the seat 16 and enhances the beauty. 3 is an external perspective view of a main part showing a use state of the seat mounting device, FIG. 4 is an exploded perspective view of the seat mounting device viewed from the inside in the width direction of the baby buggy, and FIG. 5 is an outside in the width direction of the baby buggy. It is the disassembled perspective view seen from.
The seat mounting device 19 includes a pedestal 20 that is fixed to a front frame 12 that is a pipe frame having a D-shaped cross section, and a seat coupling body 21 that is coupled to the seat 16.
The front frames 12 arranged on the left and right sides of the baby buggy 11 are configured by a pipe frame having a D-shaped cross section, and the D-shaped flat portion 22 is arranged facing the baby buggy 11 in the width direction. 22 is provided with a connecting hole 23 for preventing the seat connector from being attached and a rivet attaching hole 24 for mounting a base on both sides of the connecting hole 23. In this case, by forming the front frame 12 with a pipe frame having a D-shaped cross section, it becomes easy to form the connecting hole 23 and the riveting hole 24 in the D-shaped flat portion 22, and the D-shaped flat portion. The mounting structure which can mount stably the base 20 and the sheet | seat coupling body 21 which are mentioned later to 22 is made to respond | correspond to plane. On the other hand, the outer surface of the front frame 12 has a semicircular cross section, and the semicircular smooth outer surface is exposed over the entire length.

  In addition, the rear frame 13 is also constituted by a pipe frame having a D-shaped cross section, and a plane portion thereof is arranged in front of the baby buggy 11 and a semicircular shape having a D-shaped cross section is arranged rearward. Thereby, a smooth semicircular outer surface as viewed from the rear side is exposed over the entire length. Further, when viewed from the side, the cross section is D-shaped, so that the length becomes a radial length, and the appearance of the rear frame 13 with a narrow, sharp and refreshing appearance is exposed.

  The pedestal 20 is made of a flexible material such as rubber and is formed in an L shape. The L-shaped vertical piece 25 side of the L-shaped vertical side and the horizontal side is a quadrangle corresponding to the plane portion 22 in a plane. A base connection hole 26 corresponding to the connection hole 23 of the flat surface portion 22 is opened at the center of the L-shaped vertical piece 25. Further, rivet insertion holes 27 corresponding to the rivet fastening holes 24 of the flat surface portion 22 are opened on both sides centering on the base connection hole 26. The pedestal 20 is fixed to the front frame 12 by inserting the rivet 28 into the rivet insertion hole 27 and fitting it into the rivet fastening hole 24 in a state where the connection hole 23 and the base connection hole 26 are positioned. The

  On the other hand, the L-shaped horizontal piece 29 side extends substantially horizontally from the lower end of the L-shaped vertical piece 25, and the L-shaped horizontal piece 29 embraces a part of the front frame 12. The upper surface of the horizontal piece 29 is formed as a concave arcuate surface 30 that runs along the semicircular outer peripheral surface of the front frame 12. Further, the L-shaped horizontal piece 29 is formed with an insertion groove 31 having an F-shaped cross section having recesses in the horizontal direction and a downward direction by opening one side surface and the inner surface side thereof. An L-shaped horizontal piece 35 and a lock projection 36 of a sheet coupling body 21 to be described later are inserted into and connected to the insertion groove 31.

  The above-described sheet coupling body 21 is formed in an L shape with a flexible material such as rubber, and the L-shaped vertical piece 32 side of the L-shaped vertical side and the horizontal side corresponds to the L-shaped vertical piece 25 in a plane. A connecting shaft 33 (see FIG. 5) for connecting to the pedestal connecting hole 26 and the connecting hole 23 is horizontally projected at the center part on the outer surface side of the L-shaped vertical piece 32. ing. The connecting shaft 33 is provided with an outer stopper 33a having a large end so that the seat connecting body 21 is not inadvertently detached after the seat connecting body 21 is attached to the front frame 21. The outer fastening preventing portion 33a is fastened by being pushed into the connecting hole 23 of the front frame 12 through the base connecting hole 26. Further, a thin portion 34 is formed in the horizontal direction at a bending position where the L-shaped vertical piece 32 and an L-shaped horizontal piece 35 described later are connected at right angles, and the L-shaped vertical piece 32 is allowed to be bent in the attaching / detaching direction. Thus, the detachability operability of the outer stopper preventing portion 33a is facilitated.

  On the other hand, the L-shaped horizontal piece 35 side extends substantially horizontally from the lower side of the L-shaped vertical piece 32, and the extended portion is the same F in a direction to fit into the F-shaped insertion groove 31. A lock projection 36 is formed on the lower surface and protrudes in the same F shape. The L-shaped horizontal piece 35 including the lock protrusion 36 is inserted into the insertion groove 31 of the pedestal 20, and the seat coupling body 21 is coupled to the pedestal 20. This insertion direction is recessed along the axial direction of the front frame 12, and the insertion direction is set so that the seat coupling body 21 is directed from the upper side to the lower side of the front frame 12 with the opening end surface of the insertion groove 31 facing upward. is doing. Thereby, when the seat coupling body 21 is coupled to the front frame 12, a load is applied downward to the seat coupling body 21, but the seat coupling body 21 is inserted into the insertion groove 31 in substantially the same direction. For this reason, there is no risk of detachment even when a load is applied during use.

  Further, an end portion of a sheet 16 to be described later is fixed to the square L-shaped vertical piece 32. FIG. 6 is a side view of the main part showing the connected state of the seat connector 21 and the seat 16. The seat 16 is made of a strong and soft fabric suitable for riding an infant. When the seat 16 is connected to the seat connector 21, as shown in FIG. The end portion of the sheet 16 is stitched to the inner surface side 32 a of the shape vertical piece 32 to connect the sheet 16 to the sheet connector 21. In addition, as shown in FIG. 6B, the end of the sheet 16 is formed in a bag shape so as to wrap the L-shaped vertical piece 32 from above, and only the connecting shaft 33 is exposed from this bag-shaped portion. Connect in a state of being allowed. For this reason, the sheet coupling body 21 is integrally coupled to the sheet 16 in advance. For example, as shown in FIG. 2, the sheet coupling body 21 is attached to a total of four positions on the left and right sides of one sheet 16.

  When the seat 16 is attached to the front frame 12 using the seat attachment device 19 configured as described above, prior to the attachment of the seat 16, the positions of the four plane portions 22 of the front frame 12 serving as the seat attachment positions are previously set. Each base 20 is riveted and fixed. Furthermore, each sheet coupling body 21 is fixed by, for example, sewing or bonding to the four sheet end portions corresponding to the mounting position of the sheet 16. When the seat 16 is attached, the L-shaped horizontal piece 35 and the lock projection 36 of the seat coupling body 21 are inserted obliquely downward along the front frame 12 into the insertion groove 31 of the base 20 fixed to the front frame 12. Connect together.

  Subsequently, the outer joint prevention portion 33 a of the seat coupling body 21 is pushed in from the base coupling hole 26 and coupled to the coupling hole 23 of the front frame 12. Accordingly, the seat 16 is fixed to the front frame 12 via the seat coupling body 21 and the pedestal 20. In this case, after the seat is attached, the seat 16 is prevented from being attached by the outside prevention portion 33a and is stably and reliably fixed to the front frame 12, so that there is no possibility of accidental removal. In addition, since it does not come off even if some force is applied from the outside, safety after the seat is attached is improved.

  In particular, the mounting direction of the seat coupling body 21 is the locking action that works in the axial direction of the front frame 12 by being inserted into the insertion groove 31, and the locking action that works in the horizontal direction by being horizontally connected to the connection hole 23. The sheet coupling body 21 is more stably and reliably coupled by both locking operations in opposite directions to the operation.

  Furthermore, the support region of the seat 16 can be configured by arranging a plurality of seat attachment devices 19 having a local support structure having a short length with respect to the length of the front frame 12 and the seat 16. Further, since the seat mounting device 19 can be disposed locally, the mounting area is reduced, and the seat mounting device 19 can be easily locked as compared with the case where most of the lengths of the front frame 12 and the seat 16 are locked, and simple support. It becomes a structure.

  Further, as a work for the user to attach the seat 16, the plane D 22 having a D-shaped cross section of the front frame 12 is positioned on the inner side in the width direction of the baby buggy 11, and the insertion operation into the insertion groove 31 from the inner side in the width direction. Then, the seat 16 can be attached to the front frame 12 only by pushing into the base connection hole 26 and the connection hole 23. Further, since the end of the seat is mounted on the inner side in the width direction of the front frame 12 so as to face the butted state, the seat 16 is not exposed to the outer surface side of the front frame 12, and the appearance is uncomfortable at the seat mounting portion. The beauty of baby buggy is enhanced because it is simple.

  Next, when the sheet 16 is removed, first, the L-shaped vertical piece 32 of the sheet coupling body 21 is pulled inward in the width direction, and the outer stopper preventing portion 33a is pulled out from the connecting hole 23 to release the outer stopper. Subsequently, when the seat coupling body 21 is slid in the direction opposite to the direction in which the seat coupling body 21 is inserted from the insertion groove 31 of the base 20 fixed to the front frame 12, the seat coupling body 21 is detached from the base 20. Since it comes off, the seat coupling body 21 can be removed from the front frame 12. Therefore, the seat 16 can be removed by removing the seat coupling body 21 of these four seat mounting devices 19.

7 and 8 show another embodiment of the seat mounting device, FIG. 7 is a perspective view of the seat mounting device, and FIG. 8 is an enlarged cross-sectional view of the main part of the seat mounting device.
The seat mounting device 71 includes a locking hole 73 that is formed in a horizontally long rectangular shape in a flat portion 77 of a front frame 72 formed of a pipe frame having a D-shaped cross section, and an outer clasp provided for each locking hole 73. It comprises a mechanism 74 and a locking claw 76 integrally connected to the sheet 75.

  In the case of the second embodiment as well, a pipe frame having a D-shaped cross section that makes the mounting operation of the seat 75 good is used for the front frame 72 as in the first embodiment. The D-shaped flat surface portion 77 is arranged inward in the width direction of the baby buggy, and the locking holes 73 are opened at regular intervals in the axial direction of the flat surface portion 77. Similarly, L-shaped locking claws 76 are fixed to the sheet 75 at regular intervals on the side of the sheet 75 corresponding to each of the locking holes 73, and the L-shaped bent portion side is projected.

  The outer fastening mechanism 74 includes an elevating slider 78 and a sliding guide port 79 for slidingly supporting the elevating slider 78. The elevating slider 78 has a flat plate shape and is in contact with the flat portion 77, and is disposed at a position (upward in FIG. 8) opposite to the locking position of the locking hole 73 (left side in FIG. 7). . The elevating slider 78 protrudes from the inner surface of a sliding shaft 81 having a retaining portion 80 at the inner end, and the sliding shaft 81 is elongated in the vertical direction of the flat surface portion 77. And is slidably guided in the vertical direction.

  Further, a knob 82 for sliding operation in the vertical direction protrudes from the center of the outer surface of the lift slider 78, and the user pushes the knob 82 in the vertical direction with the fingertip to move the lift slider 78 upward or downward. By performing the sliding operation, an outer fastening operation and an outer fastening release operation of a locking claw 76 described later can be performed.

  When the above-described lifting slider 78 is slid upward as shown in FIG. 7A, the lifting slider 78 slides above the locking hole 73 to open the locking hole 73. On the other hand, when the elevating slider 78 is slid downward, the elevating slider 78 closes the locking hole 73 in a state where a part of the locking side of the locking hole 73 is opened. That is, it covers and closes the opening surface of the locking hole 73 in a state where the space for the locking claw 76 is secured.

  7B, when the lifting slider 78 is slid downward with the locking claw 76 locked in the locking hole 73, the locking-side end surface 78a of the lifting slider 78 is moved. Corresponding to the plane of the L-shaped back side 76a of the locking claw 76, it has a role of locking and locking the locking state of the locking claw 76.

  Accordingly, as shown in FIG. 7A, the lifting slider 78 is slid upward and the locking claw 76 at the end of the sheet is hooked in the locking hole 73 opened, and then the lifting slider 78 is moved downward. When sliding, as shown in FIG. 7B, the locking-side end surface 78a of the elevating slider 78 locks the back side 76a of the locking claw 76, and the seat 75 is added with an external fastening action. Can be attached to the front frame 72.

  In particular, since the sliding direction of the lifting slider 78 intersects with the locking direction of the locking claw 76 (the axial direction of the front frame) and the load loading direction, the lifting slider 78 does not move carelessly. It can prevent that the latching state of the latching claw 76 removes carelessly. For this reason, the highly safe seat 75 can be attached.

  By using such a seat attachment device 71, the seat 75 can be attached to the front frame 72 only by the sliding operation of the elevating slider 78 and the operation of hooking the respective locking claws 76 at the sheet end portions into the locking holes 73. For this reason, the mounting operation of the seat 75 is facilitated, and the locking structure can be easily constructed.

  If a plurality of mounting positions of the locking holes 73 are arranged in the axial direction of the front frame 72, only the position of the locking holes 73 in the axial direction is selected and the locking position of the locking claws 76 is changed. The attachment position of the seat 75 can be easily adjusted.

9 and 10 show another embodiment of the seat mounting device, FIG. 9 is a perspective view of the seat mounting device, and FIG. 10 is an enlarged cross-sectional view of the main part of the seat mounting device.
The seat mounting device 91 includes a locking hole 93 that is formed in a horizontally long square shape in a flat portion 97 of a front frame 92 that is configured by a pipe frame having a D-shaped cross section, and an outer clasp provided for each locking hole 93. A mechanism 94 and a locking claw 96 integrally connected to the sheet 95 are configured.

  In the case of the third embodiment, as in the first and second embodiments, the front frame 92 is a pipe frame having a D-shaped cross section that makes the mounting operation of the seat 95 good. Further, the D-shaped flat surface portion 97 is arranged inward in the width direction of the baby buggy, and the locking holes 93 are opened at regular intervals in the axial direction of the flat surface portion 97. Similarly, L-shaped locking claws 96 are fixed to the sheet 95 at regular intervals on the side of the sheet 95 corresponding to each of the locking holes 93, and the L-shaped bent portion side is projected.

  The outer fastening mechanism 94 includes a left and right slider 98, a sliding opening 99, and a slider biasing spring 100. The left and right slider 98 has an H-shaped cross section, and is disposed at a position opposite to the locking position of the locking hole 93 (upward in FIG. 10), and is a sliding opening opened in the flat portion 97 at that position. 99 is arranged to allow sliding in the axial direction of the front frame 92. Further, the left and right sliders 98 are urged in the locking direction of the locking holes 93 (downward in FIG. 10) by a coiled slider urging spring 100 interposed in a compressed state in the axial direction of the sliding port 99. . Therefore, the pressing piece 101 extending in the locking direction inside the left and right sliders 98 can press and urge the locking claws 96 in the locking direction. Further, a knob 102 for sliding operation protrudes from the center of the outer surface of the left and right slider 98, and the user presses the knob 102 with a fingertip and slides the left and right slider 98 to one side and the other. The outer claw 96 can be externally attached and can be released.

  Then, in a state where the left and right slider 98 is slid in the anti-locking direction to open the locking hole 93, the locking claw 96 at the end of the sheet is inserted into the locking hole 93, and the locking claw 96 is engaged. After the left and right sliders 98 are released after being hooked in the stop holes 93, the seats 95 are attached to the front frame 92 in a state in which the left and right sliders 98 slide in the locking direction to exert an external biasing action.

  When the seat 95 is attached to the front frame 92 using the seat attaching device 91, the engaging claw 96, which is the attached engaging portion, is kept engaged with the engaging hole 93 and is further removed. Since the locking mechanism 94 can stably and reliably prevent the locking claw 96 from coming off carelessly, it is possible to secure the attachment of a highly safe sheet. By using such a seat attachment device 91, the seat 95 can be attached to the front frame 92 only by the sliding operation of the left and right slider 98 and the operation of hooking the locking claws 96 at the sheet end portions into the locking holes 93.

  Also in this case, if a plurality of mounting positions of the locking holes 93 are arranged in the axial direction of the front frame 92, only the position of the locking holes 93 in the axial direction is selected and the locking position of the locking claws 96 is changed. Thus, the mounting position of the seat 95 can be easily adjusted.
