BACKGROUND OF THE INVENTION
The present invention relates to a stroller capable of selectively changing an inclination angle of a backrest portion of a seat mounted on a stroller body.
[0002]
[Prior art and problems to be solved by the invention]
In general, in strollers used when taking infants outdoors for walks, shopping, etc., change the inclination angle of the backrest of the seat as necessary to make the infant lie down or sit down There is a proposal that can do this. That is, a holding belt that supports the backrest portion is stretched between the left and right hand barbs, and the length of the holding belt is adjusted by operating an adjustment tool provided on the holding belt. There is one that can change the inclination angle of the contact portion.
[0003]
However, in the case of changing the inclination angle of the back pad portion in this way, although it can be finely adjusted, it is necessary to change the length of the holding belt each time. Have problems such as the necessity of using both hands and the difficulty of operation while holding an infant.
[0004]
In view of the above, an object of the present invention is to provide a stroller that can easily change the inclination angle of the backrest portion.

[Means for Solving the Problems]
The invention according to claim 1 is a stroller in which the inclination angle of the back support portion of the seat mounted on the stroller body can be changed, and the head protector is foldably connected to the top edge of the back support portion. A holding belt extending in the left-right direction is attached to the tip of the head protector, and the left and right sides of the holding belt are fixed to a sliding body that is slidably attached to the left and right hand pushers, and the holding belt is slid. The inclination angle of the backrest portion can be changed by moving together with the moving body .
[0006]
The invention according to claim 2 is the invention according to claim 1, wherein the head protector is stretched between the top edge of the back rest and the holding belt when the back rest is in a lying state, When the back rest is in a standing state, the back rest is folded to the back side of the back rest and the back rest is supported by the holding belt.
[0007]
The invention according to claim 3 is the invention according to claim 1 or 2, wherein a handle is provided on the back side of the holding belt.
[0008]
According to a fourth aspect of the present invention, in the first or second aspect of the present invention, the left and right hand barbs are provided with a locking portion that prevents the sliding body from moving at the moving end of the sliding body. Features.

DETAILED DESCRIPTION OF THE INVENTION
1 and 2 are perspective views showing a schematic configuration of a stroller with a reclining mechanism of the present invention. A stroller body 10 includes a pair of left and right front legs 12 having a twin-wheel front wheel 11 and a twin-wheel rear wheel 13. A pair of left and right rear legs 14, a push bar 15 bent in a substantially inverted U shape, and a pair of left and right armrests 16. The left and right rear legs 14 and the left and right pipes 15 a constituting the hand bar 15 are connected by an X-shaped connecting bar 17. Further, a horizontal hook (not shown) protruding forward from the front leg 12 is integrally formed on the upper part of the left and right rear legs 14, and a seat support belt (not shown) is formed between the left and right horizontal hooks. The seat plate 21 of the infant seat 20 is placed and supported on the seat support belt. That is, the seat plate portion 21 of the seat 20 is usually configured by covering a core material with a cushion material, and the distal end portion of the seat plate portion 21 is fitted to the distal end portions of the left and right horizontal hooks (not shown). At the same time, the central portion is supported by the seat support belt.
[0010]
As with the seat plate portion 21, a backrest portion 22 configured by covering the core material with a cushion material is connected to the seat plate portion 21 so that the inclination angle can be changed. . That is, the backrest 22 is formed so as to be reclining. By the way, the side 22a is formed in the both right and left sides of the said backrest part 22, The side is latched by the upper part of the front leg 12. As shown in FIG. FIG. 1 shows a standing state in which the back pad 22 is lifted upward, and FIG. 2 shows a lying state in which the back pad 22 is tilted backward from the position shown in FIG.
[0011]
As shown in FIG. 3, a cloth-foldable head protector 23 is connected to the top edge of the back pad 22. A holding belt 24 extending in the left-right direction is mounted on the upper back side of the head protector 23, and both ends of the holding belt 24 are slidably provided on the left and right pipes 15a of the hand bar 15 respectively. It is fixed to the moving body 25.
[0012]
The left and right pipes 15 a of the hand bar 15 are provided with locking portions 26 that are urged in a protruding direction by springs at the moving end portions of the sliding body 25. Further, the sliding body 25 is provided with an engagement hole 25a that can be engaged with the locking portion 26. When the sliding body 25 comes to each moving end, the engagement hole 25a becomes the pipe 15a. It engages with a locking portion 26 provided on the head and is held in that position. On the other hand, a handle 27 is attached to the back side of the holding belt 24.
[0013]
Further, the left and right side portions of the backrest portion 22 are connected to the pipe 15a of the hand bar 15 by a belt 28 of an appropriate length having a connecting tool 28a.
[0014]
FIG. 4 is a perspective view seen from the back side when the backrest 22 of the seat 20 is substantially upright, and the sliding body 25 is held at the position of the downward movement end together with the holding belt 24. . In this case, the head protector 23 is folded to the back side of the back pad part 22 and is brought into contact with the back surface of the back pad part 22 by the holding belt 24, and the back belt part by the holding belt 24. 22 is supported in the standing state. FIG. 5 shows the standing state of the backrest 22.
[0015]
Therefore, when the backrest portion 22 is in the lying state, the left and right sliding bodies 25 are lifted upward together with the holding belt 24 by holding the handle 27, and the engaging hole 25 a of the sliding body 25 is detached from the locking portion 26. When the sliding body 25 is further moved upward along the pipe 15a, the backrest portion 22 tilts backward, and the head protection body 23 is deployed as shown in FIG. As a result, the top end portion of the backrest portion 22 is supported and brought into a lying state. FIG. 6 shows the lying state of the backrest 22.
[0016]
On the other hand, in order to change the state from the state to the standing state, the back support part 22 is moved downward together with the holding belt 24 through the handle 27 while the back support part 22 is pushed forward, thereby moving the back support part The back support portion 22 can be supported by the holding belt 24 in the upright state shown in FIGS. 4 and 5.
[0017]
Further, by attaching a length adjusting device to the holding belt 24, fine adjustment can be performed in the middle of the state shown in FIGS.
[0018]
【The invention's effect】
As described above, the present invention connects the head protector in a foldable manner to the front edge of the backrest portion of the seat mounted on the stroller body, and extends the front end of the head protector in the left-right direction. Since it is attached to the holding belt and the left and right sides of the holding belt are fixed to the sliding body that is slidably attached to the left and right pipes of the hand barb, the backrest is simply moved up and down together with the sliding body. The inclination angle of the part can be selectively changed, and the change can be performed very easily.
