Abstract

The invention provides a foldable chair. The foldable chair comprises a chair leg, a chair back and a seat, wherein the chair leg is formed by a stand column; the bottom side of the seat is fixedly provided with a connection piece; two wings of the connection piece are bent toward the lower side and are mutually parallel; the upper end of the stand column is arranged between the two wings of the connection piece; the upper end of the stand column is connected with the two wings of the connection piece through a rotary pin; the rear side of the seat or the rear side of the connection piece and the lower part of the chair back are connected through a hinge; and a limiting mechanism is arranged between the rear side of the seat or the rear side of the connection piece and the stand column. A fixed plate at the lower end of the stand column is fixed with the ground. The seat is rotated forwards by taking the rotary pin as the axis; the chair back and the seat are unfolded and the limiting mechanism pulls the rear side of the seat to fix an angle between the seat and the stand column; the lower end of the chair back is placed at the rear side of the stand column in a biased manner; and the angle between the chair back and the seat is fixed and the foldable chair is unfolded. The foldable chair disclosed by the invention utilizes one stand column to support the seat and the occupied area of the chair leg is small; and three layers of parallel foldable mechanisms are formed when the chair back, the seat and the stand column are folded, so that the occupied space is small.
一种折叠椅,包括椅脚、椅背和椅座,椅脚由一个立柱构成,椅座的底侧固定设置有一个连接件,连接件的两翼向下侧弯折后相互平行,立柱的上端设置在连接件的两翼之间,立柱的上端与连接件的两翼通过一个转动销连接,椅座的后侧或者连接件的后侧与椅背的下部之间通过铰链连接,椅座的后侧或者连接件的后侧与立柱之间设置有限位机构。立柱下端的固定板与地面固定。以转动销为轴向前转动椅座,椅背与椅座展开,限位机构拉住椅座后侧将椅座与立柱之间的角度固定,椅背下端偏置在立柱后侧,将椅背与椅座之间角度固定,折叠椅完成展开。本发明利用一个立柱支撑椅座,椅脚占用面积少,椅背、椅座和立柱则折叠时可形成三层平行的折叠机构,占用空间少。
