Embodiment Construction

[0053] Specific embodiment 1 of the present invention, with reference to Fig. 1 to Fig. 4, a straight-leg type folding chair frame includes a transverse frame 1, four chair legs 21, 22, 23, 24, and two frame bars 31, 32.

[0054] Wherein, the four chair legs 21, 22, 23, 24 do not cross each other, that is, they do not cross each other like traditional folding chairs, and the lengths of the left front and right front legs 23, 22 are shorter than the left rear and right. The chair legs 24, 21 on the rear side are pivotally connected to the cross frame 1 at the same height; the cross frame 1 is used to connect with the seat board of the folding chair, and is composed of a front side bar 12, a left side bar 13 and a right side bar 11 The rear end portions of the left side bar 13 and the right side bar 11 respectively form conflicting surfaces, and are respectively in contact with the front sides of the two chair legs 24, 21 on the rear side, and the opposite sides of the left side ...

Abstract

The frame of straight leg type folding chair includes one transverse frame in the rectangular structure with four pivot jointing points; four chair legs parallel basically and pivoted separately to the four pivot jointing points. The four chair legs can rotate relatively to the transverse frame within the vertical plane in the backward-and-forward direction. The present invention realizes folding chair with straight legs and capable of being folded in only one step, and combines the advantages of both staggered form folding chair with convenient folding and straight leg chair with high fastness and durability.

Description

technical field [0001] The invention relates to a folding chair, in particular to a folding chair frame and a folding chair in which four chair legs are in a vertical direction without crossing each other. Background technique [0002] Folding chairs are one of the common furniture in offices or homes, and are widely used because they can be conveniently folded and stored when not in use. [0003] Folding chairs in the prior art are usually cross-folding, and their frames mostly include two leg support frames and a seat surface support frame. Forming the support frame of the backrest, the length of the chair leg support frame on the rear side is about half of the length of the front side chair leg support frame, and its top is connected with the approximately middle position of the front side chair leg support frame through two first connecting pieces. The two sides of the surface support frame are rotatably connected to the chair leg support frame on the front side, and ar...
