Description

[Detailed explanation of the idea] The present invention relates to a folding chair.

In other words, it is constructed by assembling two frames with a dogleg shape on the sides, and when the chair is folded, the whole chair can form a dogleg shape on the sides, making it possible to fit many chairs together and store them well even in a narrow space. The device can be easily stored horizontally or vertically, has a compact structure, and can be manufactured easily and suitably.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the entire chair, which is constructed by assembling a frame A and a frame B. Frame A has a side surface with rear legs 1 on the lower side of bent part A and back part 2 on the upper side. Both frame rods aa in the shape of letters are made parallel, and the upper ends of both frame rods a, a are connected by an integrated horizontal rod 7, a backrest 8 is installed along the horizontal rod 7, and both frame rods a, Rotating joints 5, 5 are installed inside the bent portions (a) and (a), respectively.

In addition, the frame B has both side frames having a dogleg shape, with the front legs 3 on the lower side and the seat 4 on the upper side of the bending part opening, and b being parallel to each other.

The upper ends of b are connected by an integrated horizontal rod 9, and both seat parts 4.4
and the seat body 10 is installed across the horizontal rod 9, and both frames are connected, b
Rotation joints 6.6 are installed inside the bent portions (b) and (b), respectively.

A frame B is fitted inside the frame A, and the plane rotation joints 1-6 and 6 of the frame B are aligned with the inner side of the plane rotation joints 5 and 5 of the frame A, so that they are rotatably connected to each other, The surface rotation joints 5 and 6 are structured so as to prevent rotation beyond a certain rotation angle.

Therefore, by rotating the rotation joints 5 and 6 so that the front legs 3 and the rear legs 1 are unfolded in an inverted V shape, the user can sit on the seat body 10 and lean against the backrest 8 while sitting on the chair.

In addition, when storing the chair, rotate the rotating joints 5 and 6 relative to each other as shown in FIG. 7, and rotate the frames A and B in the direction in which they overlap, as shown in FIG. 8. Frame A and frame B, which have a dogleg shape on their sides, can be folded so that they overlap, and when the chairs are folded in a dogleg shape, they are placed side by side as shown in Figure 9.
The entire device can be stored either horizontally or vertically in a small space.

In this way, the present invention consists of a frame A consisting of both side frame rods a, a, which have a dogleg-like shape, with the side below the bent part A becoming the rear leg 1, and the upper side tilting backwards to form the back part 2; Frame B, which consists of both side-shaped dog-shaped frame rods whose sides become the front legs 3 and whose upper side becomes the seat 4, is connected through rotation joints 5 and 6 that can regulate the angle at each bending part 19. When in use, the front legs 3 and rear legs 1 can be unfolded in an inverted V shape for a comfortable sitting position, and when not in use, both frames can be rotated around rotation joints 5 and 6. By rotating A and B, the whole chair can be folded into a dogleg shape on the sides, and by putting the folded chairs together in a dogleg shape, you can store a large number of them in a small space. The chair itself can be stored either vertically or horizontally, and the chair itself has a compact frame structure, making it easy to manufacture and suitable for implementation.
