[Prior art]
FIG. 5 is a partially cutaway perspective view showing a schematic configuration of a hammock-type baby stroller in which an infant seat is suspended from a baby stroller body, and a pair of left and right front legs 12 having a front wheel 11 and a pair of left and right front wheels having a rear wheel 13. The stroller body is constituted by the rear leg 14, the hand bar 15 bent in a substantially inverted U shape, and the pair of left and right armrests 16. A detachable guard arm 17 is stretched between the left and right armrests 16 and 16. One end of the armrest 16 is pivotally attached to the vicinity of the distal ends of the left and right pipes 18 constituting the hand pusher 15, and the top end of the front leg 12 is pivotally attached to the other end of each armrest 16. . The top ends of the left and right rear legs 14 are also pivotally attached to the middle part of the armrest 16, and one end of a bracket 19 bent in a square shape is pivotally attached to the middle part of the rear leg 14. The ends of the pipes 18 are pivotally attached to the intermediate positions of the brackets 19, and the lower ends of the pipes 18 are engaged with the engaging portions formed at the other end of the brackets 19 when the stroller is deployed. The lock member 20 that is slidably mounted on the lock member 20 is engaged with the lock member 20, and the unfolded state is maintained.
[0003]
On the other hand, the left and right front legs 12 are connected by a front connection bar 21 having a footrest, and the left and right rear legs 14 are connected by a rear connection bar 22. Further, the front end of the connecting bar 23 is pivotally attached to the middle portion of each front leg 12, and the rear end of the connecting bar 23 is pivotally attached to the tip end portion of the pipe 18 together with the bracket 19. The portions are connected by a stay 24 extending in the left-right direction.
[0004]
Thus, by engaging the locking member 20 provided at the lower end of the pipe 18 with the engaging portion provided at the upper end of the bracket 19, the stroller is held in a usable state. On the other hand, when the engagement between the locking member 20 and the bracket 19 is released by operating the operating device 25 provided on the hand bar 15, the armrest 16 and the connecting bar 23 are respectively connected to the pipe 18. The front leg 12 and the rear leg 14 are swung in a substantially parallel state with the pivot point as the center, and can be folded for convenient portability.
[0005]
Further, the hand bar 15, the front side connecting bar 21, the rear side connecting bar 22, and the stay 24 can be folded by joints at two places in each intermediate portion in two identical vertical planes. Therefore, when the left and right pipes 18 are moved forward after the front leg 12 and the rear leg 14 are folded in parallel as described above, the hand barb 15, the front connection bar 21, the rear connection bar 22, and the stay 24 are moved. Both ends of the baby can be folded forward, and the stroller can be folded in a tri-fold state.
[0006]
Incidentally, infant seats 26 are attached to the left and right pipes 18 and the connecting bar 23. That is, the back portion of the infant seat 26 is attached to the left and right pipes 18, and the seat surface portion is attached to the left and right connecting bars 23, and is hung in a so-called hammock shape. The seat 24 is supported by the stay 24.
[0007]
However, in such a hammock type baby stroller, since the plate-shaped core material is embedded in the seat surface portion, the seat surface portion is stable without moving in the left-right direction. Since it is only supported by one extending stay 24, there is a problem that it is extremely unstable at the front and rear positions. In view of this, it has been proposed that a seat surface support member extending in the front-rear direction is provided on the stay 24 to prevent the seat surface portion from swinging around the one stay 24 extending in the left-right direction. ing.
[0008]
On the other hand, in a stroller, when the back part is fully reclined, the footrest for allowing the legs to be extended and placed can be freely put in and out according to the posture of the infant. It has also been proposed.
