[Prior art]
FIG. 2 is a partially cutaway perspective view showing a schematic configuration of a hammock-type baby stroller in which a baby 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 right and left having a rear wheel 13. The stroller body is constituted by the rear leg 14, the hand bar 15 bent in a substantially 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. . Further, the top end portions of the left and right rear legs 14 are also pivotally attached to the intermediate portion of the armrest 16, and one end of a bracket 19 bent in a square shape is pivotally attached to the top end portion of the rear leg 14. The ends of the pipes 18 are pivotally attached to the intermediate positions of the brackets 19, and in the deployed state of the stroller, the sliding portions are slid onto the lower ends of the pipes 18 in the engaging portions formed at the other ends of the brackets 19. The lock member 20 movably mounted is engaged and maintained in its expanded state.
[0003]
On the other hand, the left and right front legs 12 are connected by a front connection bar 21, 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 parts are connected by a stay 24.
[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 lock member 20 and the bracket 19 is released by operating the operating device 25 provided in the hand barb 15, the armrest 16 and the connecting bar 23 are pivotally attached to the pipe 18. The front leg 12 and the rear leg 14 are swung in a substantially parallel state, and can be folded for convenience of carrying.
[0005]
Furthermore, the hand bar 15, the front side connecting bar 21, the rear side connecting bar 22, and the upper side connecting bar 24 can be folded by two joints at 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 bar 15, the front connection bar 21, the rear connection bar 22, and the upper connection bar Both ends of 24 are folded forward, and the stroller can be folded in a three-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]
[Problems to be solved by the invention]
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 rod-like stay 24, there is a problem that it is extremely unstable in the front-rear direction. In view of the above, an object of the present invention is to provide a stroller that can improve the stability of a seating surface portion of a seat.
[0008]
[Means for Solving the Problems]
The present invention provides a hammock type stroller including a stroller body, which is provided separately from a front leg and a rear leg, a left and right connecting bar for connecting the front leg and the rear leg, and a left and right connecting bar, and connecting the connecting bars to each other. with the door, so as to support the seating surface of the seat which is suspended in the stroller body by a stay, in the stay, that projecting from the seating surface support member extending longitudinally from its stay in connecting bar and separate It is a hammock type stroller.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIG.
[0010]
FIG. 1 is a partial view showing only a main part of the stroller of the present invention. A front end of a connecting bar 23 is pivotally attached to an intermediate portion of each front leg 12, and a rear end of the connecting bar 23 pivots to a rear leg 14. Together with the worn bracket 19, it is pivotally attached to the tip of the pipe 18, and the middle part of the left and right connecting bars 23 is connected by a stay 24. The stay 24 is provided with joints 24a and 24b at two intermediate portions thereof and can be folded by the joints 24a and 24b.
[0011]
Although these configurations are the same as the conventional ones, in the present invention, the stay 24 is provided with a seating surface support member 30 extending in the front-rear direction at two locations outside the joints 24a and 24b. .
[0012]
When the infant seat 26 is suspended from the stroller body as described above, the seat member, particularly, the core material 26a provided in the seat member, extends not only from the stay 24 but also from the stay 24 in the front-rear direction. It is supported by the surface support member 30.
[0013]
Thus, the seat surface of the seat is supported by the seat surface support member 30 extending in the front-rear direction from the stay 24, and the seat surface does not swing around the stay 24 as in the prior art, and the stability of the seat surface can be improved. it can.
