Description

Chair

Technical field

The present invention relates to a kind of chair, but particularly a kind of simple operations is folding, the chair that launches, when folding frivolous and be convenient to hold take, storage and transportation.

Background technology

The formation of general chair is nothing more than comprising chair cushion, chair pin or adding the chair back, and traditional Chair structure all is fixing and can't fold, make it be not easy to storage, transportation or use, therefore, just developed a variety of chairs that can fold and launch to use on the market, and those foldable chairs still have following several disappearances at present:

1, the complex structure of some folding seat not only makes the cost raising of manufacturing and operates comparatively inconvenience.

2, because the problem of structural design, the thickness after making chair folding is too big and length is oversize, and therefore out-of-flatness again is unfavorable for storage, transports or carry.

3, traditional folding seat is inconvenient to hold after folding take, or does not have the position to allow the people grip, thus when carrying the user all at will grab a place and operate, very inconvenient, therefore, be unfavorable for the carrying out that carries and move.

Therefore, how can take into account have easy and simple to handle fast and folding back thin thickness comparatively smooth again light and handy, be suitable for holding taking and extract and pile up, store in a warehouse, transport, be the main problem of the present invention.

Summary of the invention

In view of this, the invention reside in a kind of simple in structure, easy to operate foldable chair is provided.

The present invention time is beneficial to the Chair structure that piles up, stores, transports in that a kind of very smooth after folding, thin thickness, moderate length are provided.

The present invention is in addition providing a kind of structure of chair, holds well after it is folding to take and be convenient to portable, carrying, move etc.

Edge this, chair of the present invention includes:

One chair cushion, this chair cushion have a front side, a rear side, a left side, a right side, top, a bottom;

One rail set is located at the chair cushion bottom or the left and right sides, and is provided with on the direction of rear side in the front side;

One slide bar is arranged at aforementioned rail set movably;

One first chair pin, but this first chair pin swing ground is located at the rear side of chair cushion bottom with an end axle, and the other end then is a free end;
