Folding chair with back rest

Abstract

The invention is a novel model involving a folding chair with back rest, including small U-shaped bars, large U-shaped bars, and back rest U-shaped bars. The small U-shaped bars and large U-shaped bars' two ends have short vertical bars and long vertical bars cross-hinged to form supports. The backrest U-shaped bars' two backrest vertical bars are hinged on the large U-shaped bars' two long vertical bars top outside face. This forms a back rest weight support, and the two backrest vertical bars will tighten the back rest fabric. In this: the small U-shaped bars' two corners become a narrowing structure, shrinking the length of the short horizontal bar, and the soft stool surface forms a trapezoid shape. This uses a new small U-shaped bar two corner narrowing structure, which creates definite space in the corners to avoid the short horizontal bar top from blocking the legs.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The invention is to a new design used in the leisure chairs field, especially for a kind of folding chair with back, particularly for a kind of foldable, flat-folding stool.SUMMARY OF THE INVENTION[0002]Two sides of two rectangular frames become an X cross-hinge, and the folding stool formed is at once an ancient and commonly seen stool, especially in that the stool surface uses a soft fabric or strap, enabling the structure to be more simple. Additionally, when sitting it is possible to choose two cross hinges that join into a forward and back part. In this way the legs will not be obstructed by the rectangular frame horizontal bars, and therefore sitting is more comfortable, but without using the back rest. For this, the manufacturers add back rest rectangular frames, creating a folding stool that has back rest functionality. The structure has a small rectangular frame, a large rectangular frame, and a back rest rectangular...
