Description

[Detailed Description of the Invention] The present invention relates to a folding chair in which a seat is formed by stretching cloth between a pair of X-shaped legs that can be opened and closed.

As shown in Fig. 1, the conventional structure of a folding chair with a pair of X-shaped legs that can be opened and closed is as follows:
The tips of the legs 1a, 2a and 1b, 2b are connected by horizontal shafts 4, 5, and a cloth 8 is connected between the horizontal shafts 4, 5.
It is a structure that spans the And legs 1a and 1b
And by opening the legs 2a and 2b, the horizontal axes 4 and 5
The cloth 8 stretched between them is stretched to form a seat surface,
It is folded by closing the legs. In this case, the seat can only be used at a constant height when the legs are spread, and there is a drawback that the height of the seat cannot be adjusted according to the user's height.

The object of the present invention is to provide a folding chair whose seat height can be adjusted to suit a wide range of heights from adults to children.

The feature of this invention is that horizontal shafts are provided in multiple stages at required intervals between the intersection point and the tip of a pair of X-shaped legs, and when the legs are opened, the cloth is swirled between the horizontal shafts in the same stage. The seating surface is formed by spanning the shape of the seat.

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4.

X-shaped legs 1a, 1b and 2 with pivoting points 3
Horizontal shafts 4a, 4b, 4 in which pairs of a and 2b are arranged in multiple stages at required intervals from the intersection point 3 to the tip.
Connect at c, 4d and 5a, 5b, 5c, 5d. Also, if necessary, the horizontal axes 6a, 6b, 6c, 6d and 7
a, 7b, 7c, and 7d may be arranged.

Then, the horizontal axes 4a to 4 of the same stage when the legs are spread
A seat surface is formed by spirally wrapping a cloth 8 between d and 5a to 5d. This wrapping of the cloth 8 is done by starting from one end and wrapping it upward from the bottom of one of the horizontal shafts 4a, wrapping it from the top of the other horizontal shaft 5a to the bottom, and then wrapping it again from the bottom of the horizontal shaft 4a to the top. It is formed by winding the winding end 10 over the other horizontal shaft 5a and letting the winding end 10 hang down.

Therefore, the height of the seat surface can be adjusted by selecting the horizontal axes 4d, 5d at the lowest level from the horizontal axes 4a, 5a at the uppermost level. Furthermore, even with the same combination of horizontal axes 4a to 4d and 5a to 5d, the height of the seat surface can be arbitrarily adjusted by changing the angle of the legs apart by changing the length of the cloth 8 wrapped around it. It is possible.

Furthermore, when the horizontal axes 6a to 6d and 7a to 7d are provided, the seat surface is formed by wrapping the cloth 8 in any of the four directions of the spread legs.

Further, the cloth 8 spirally wrapped around the horizontal axes 4a to 4d and 5a to 5d maintains the tension of the seat surface by friction between the cloth 8 due to the weight of the person and the horizontal axes 4a to 4d and 5a to 5d. It is.

As described above, according to the present invention, the seat height of the cloth stretched between the horizontal shafts can be adjusted by a simple operation, and a wide range of seat heights can be obtained from adults to children. Since it is removable, you can wash it when it gets dirty. Furthermore, since the pair of X-shaped legs are connected by a plurality of horizontal shafts, there is an advantage that the strength of the legs is increased.
