Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hammock type stroller in which an infant seat is suspended from a stroller body, and more particularly, a hammock in which a seat surface portion of the seat is supported by a stay that connects left and right connecting bars that connect a front leg and a rear leg. It relates to type strollers.
[0002]
[Prior art]
FIG. 3 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 barb 15, the front connection bar 21, the rear connection bar 22, and the stay 24 can be folded by joints 21a, 22a, and 24a at two intermediate portions 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 are folded forward by the joints 21a, 22a, 24a, 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 26a of the infant seat 26 is attached to the left and right pipes 18, and both side portions of the seat surface portion 26b are attached to the left and right connecting bars 23, and are 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, the seat surface portion 26b is stable because it does not move in the left-right direction because the plate-like core material is housed in the seat surface portion 26b. Since it is only supported by one stay 24 extending in the left-right direction, there is a problem that the seat surface portion 26b swings up and down around the stay 24 and is extremely unstable at the front and rear positions. Therefore, a support belt 27 is stretched between the left and right connecting bars 23 on the rear side of the stay 24, the seat surface portion 26b is supported by the support belt 27 and the stay 24, and the seat surface portion 26b extends in the left-right direction. There has been proposed one that prevents swinging about one stay 24.
[0008]
[Problems to be solved by the invention]
However, in the case where the seat surface is supported by the stay 24 and the support belt 27 stretched between the left and right connecting bars 23, as shown in FIG. In addition, the seat 26 is moved in the direction to be pushed backward by the stay 24 and the front connecting bar 21. At this time, the support belt 27 is resistant to the tri-folding operation, and requires a high operating force at the time of the tri-folding. There is a problem such as. Therefore, if the support belt is set to be long, there is a problem that the seat surface portion is not sufficiently supported when the stroller is used, and the sinking is increased at the rear portion of the seat surface portion.
[0009]
In view of these points, an object of the present invention is to provide a stroller that can improve the stability of a seat and can easily operate a stroller body to a tri-fold state. .
[0010]
[Means for Solving the Problems]
The present invention is a hammock type stroller that supports a seat surface portion of a seat suspended from a stroller body by a stay that connects left and right connecting bars that connect the front leg and the rear leg. It is supported by suspension belts attached to the left and right pipes constituting the hand bar. The suspension belt is stretched between the rear side lower surface of the seat surface part and the left and right pipes constituting the hand bar. It is a hammock type stroller.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention will be described below with reference to FIGS.
[0013]
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. It is pivotally attached to the tip of the pipe 18 together with the worn bracket 19, and the middle part of the left and right connecting bars 23 is connected by a stay 24 extending in the left-right direction. The stay 24 is provided with joints 24a and 24a at two intermediate portions, and the joint 24a and 24a can be folded.
[0014]
Although these configurations are the same as the conventional ones, in the present invention, two suspension belts 30, 30 are sewn on the lower surface in the vicinity of the rear portion of the seat surface portion 26b, and each suspension belt 30, 30 is sewn. Are fixed to the left and right pipes 18. That is, the suspension belt 30 is stretched between the lower surface of the seat portion 26 b and the left and right pipes 18 constituting the hand bar 15. In addition, the code | symbol 31 in a figure is a hood attachment part.
[0015]
Thus, when the stroller body is deployed, the seat surface portion 26b that is suspended from the left and right connecting bars 23 and is mounted on the stay 24 that extends in the left-right direction has the left and right suspension belts at the rear. The seat surface portion 26b is prevented from swinging in the vertical direction.
[0016]
On the other hand, when the stroller body is folded in two, the left and right connecting bars 23 swing upward about the pivot point with the pipe 18, and as shown in FIG. The distance between the attachment position to the surface portion 26b and the attachment position to the pipe 18 is shortened, and as a result, the suspension belt 30 is loosened. Therefore, when the three-fold state is set thereafter, the suspension belt 30 does not become resistant to the three-fold operation, and the three-fold operation can be easily performed.
[0017]
【The invention's effect】
Since the present invention is configured as described above, the seat portion of the hammock-type seat is supported by the suspension belt, and the seat portion is prevented from swinging around the stay and moving back and forth. As a result, the stability of the seating surface portion is improved. In addition, when the stroller body is folded in three, the suspension belt does not become a resistance to the trifold operation, and the trifold operation can be easily performed.
