Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding chair which can be easily folded to the front legs by pulling up a backrest.

[0002]

2. Description of the Related Art A conventional folding chair 1, as shown in FIG. 4, folds a seat portion 2 by lifting it up to a backrest 3 side and connects front seat legs 2 supported by the seat portion 2 with rear legs. Many of them have a structure in which they are folded so that they are stacked on top of each other.

[0003]

However, in such a structure, when folding, both hands must be used such that one hand grasps and supports the backrest 3 and the other hand pulls up the seat 2. Since the seat portion 2, the backrest 3, the front legs 4 and the rear legs 5 are rotatably connected to each other with a certain amount of resistance, the seat portion 2 and the other connecting portions are rotated. I had to push it with my hands to push it, and it was difficult to arrange and put away the chairs quickly. The present invention has been proposed from the background described above, and an object thereof is to provide a folding chair that can be folded more easily and speedily.

[0004]

In order to solve the above-mentioned problems, the present invention relates to a folding chair in which a rear leg is rotatably attached to an upper side of a front leg and one end side of a seat is attached to an intermediate portion of the front leg. It is rotatably attached, and the backrest is rotatably attached to the other end side of the seat portion, the armrest is connected so as to bridge the backrest and the front leg apex, and the lower surface of the seat portion and the rear leg are connected by an interlocking stay. Then, by raising the backrest, the seat is rotated through the backrest to stand up to the front legs, while the armrest is rotated to stand up on the front legs, and the interlocking stays are interlocked displacement by standing up the seat. Then, the restraint of the rear leg is released, and the rear leg is superposed on the front leg.

[0005]

[Operation] When the backrest is pulled up, the armrest rotates and displaces around the connection point with the front leg top, while the seat is pulled up through the backrest and displaces around the connection point with the front leg. Then it rises. When the seat portion is pulled up, the rear legs are unconstrained by the displacement of the interlocking stays, so that the rear legs are overlapped along the front legs and the entire folding is completed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A folding chair according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a folding chair 10, which has a structure having front legs 11, rear legs 12, a seat portion 13, a backrest 14, and an armrest 15.

As shown in FIG. 2, the front leg 11 is made to stand upright on the floor with its upper part slightly inclined rearward, and the front legs 11 are placed at the middle position of the front leg 11. It is connected by 16.

The rear leg 12 has a curved upper end portion, which is a connection portion with the front leg 11, is connected to the front leg 11 by a hinge (not shown) or the like, and has a lower end portion at a position apart from the front leg 11. The side surfaces formed by the front legs 11 and the rear legs 12 are formed so as to have a triangular shape like a stepladder so as to be in contact with the floor surface. The rear legs 12 are connected to each other by a crosspiece 17.

The seat portion 13 has a cushion portion 19 mounted on a frame 18, and has a pair of front legs 11 on the front end side.
The frame 18 is slightly projected forward, one end of the frame 18 is rotatably attached to the crosspiece 16 of the front leg 11, and the other end of the frame 18 is connected to a post of a backrest 14 described later. The frame 18 and the rear leg 12 are connected to each other by an interlocking stay 20, and a lower portion of the rear leg 12, which is a ground contact point with the floor surface, blocks rearward movement.

The backrest 14 has a pair of backrest columns 21 connected to the other end of the frame 18, and a backrest 22 is attached to the upper ends of the backrest columns 21. The back support portion 22 is covered with a cushioning member.

The armrests 15 are provided so as to extend from both ends of the back support portion 22 to the top of the front leg 11, and
It is pivotally fixed to the top.

In the folding chair 10 having the above-described structure, the front legs 11 and the rear legs 12 are grounded on the floor so that the side faces form a triangle, just like a stepladder, and the rear legs 12 are grounded.
The upper part is rotatably connected in the vicinity of the front end of the upper part of the front leg 11, while the interlocking stay 20 of the frame 18 in the seat part 13 supports the lower part of the rear leg 12 so as not to open rearward. No problem.

Here, when folding the folding chair 10, the backrest 22 is held and pulled up.
Then, the armrest 15 connected to the back rest 22 is rotationally displaced by the weight of the chair itself around the connection point with the top of the front leg 11 while the seat 13 is pulled up via the backrest column 21, The front leg 11 is rotated around the connection point with the crosspiece 16 and raised. As the seat portion 13 is pulled up, the connecting portion between the frame 18 and the interlocking stay 20 moves upward, so that the interlocking stay 20 is displaced and the rear leg 1
No. 2 is released from the restraint by the interlocking stay 20, and is overlapped along the front leg 11 side, and the entire folding is completed (FIG. 3).
reference).

As described above, the folding chair 10 according to the present embodiment can be folded by holding the back rest portion 22 and pulling it up. As in the conventional case, the backrest is grasped and supported by one hand. There is no need to use the other hand to pull up the seat to the backrest side, which makes setting and folding of the chair much easier.

The folding chair 10 according to the present embodiment.
The structure of can also be applied to ordinary so-called pipe chairs, chairs in conference rooms, and the like.

[0016]

As described above, according to the present invention, it is possible to fold quickly and easily as compared with the conventional folding structure, and it is possible to efficiently set up and withdraw.
