Embodiment 1

[0034] refer to figure 1 and figure 2 , a folding chair, including a cross-folding support frame 1, a seat plate 2 and a back plate 3. This cross-folding support frame 1 comprises two X-shaped cross-folding bars, and each X-shaped cross-folding bar includes front chair legs 12, 14 and rear chair legs 11, 13 which are pivotally connected to each other in the middle position, and the two front chair legs The upper ends of 12, 14, that is, the front ends, constitute the first upper end of the cross-folding support frame 1, and the upper ends, that is, the rear ends, of the two rear chair legs 11, 13 constitute the second upper end of the cross-folding support frame 1, The first upper end portion and the second upper end portion can be folded against each other. The upper ends of the two front chair legs 12 , 14 are integrally connected by a cross bar 15 .

[0035] The upper ends of the two rear chair legs 11 , 13 extend upward to form two back bars 111 , 131 , and a back plat...

Embodiment 2

[0042] The main structure of this embodiment is the same as that of Embodiment 1. The main difference is that the armrest structure is added. The same parts will not be described in detail below. The above-mentioned Embodiment 1 can be referred to. The following mainly describes the armrest structure.

[0043] refer to Figure 7 and Figure 8 , in addition to having the same structure as Embodiment 1, this embodiment also includes armrest bars 51, 53 and armrest support bars 52, 54, the rear ends of the armrest bars 51, 53 are pivotally connected to the back bar 111, 131, the front ends are respectively pivotally connected to the upper ends of the armrest support rods 52, 54, and the lower ends of the armrest support rods 52, 54 are integrally connected by a cross bar 55, which is rotatably pivotally connected to the first seat plate 2 The two sides are the back side.

[0044] The rear ends of the two armrest bars 51, 53 are pivotally connected to the outer sides of the two ...

Abstract

A folding chair comprises a cross-folding support frame, a chair plate and a support rod. The cross-folding support frame comprises two X-type cross-folding rods. each cross-folding rod comprises two front chair legs and two rear chair legs which are crossly articulated with each other at the middle position, wherein, the upper end parts of the two front chair legs form a first upper end part, and the upper end parts of the two rear chair legs form a second upper end part; the chair plate has a first side edge and a second side edge, and the first side edge and the second side edge or the position near the first side edge and the second side edge are pivoted with the first upper end part of the cross-folding support frame; the support rod which can slide between the first side edge and the second side edge is arranged on the bottom surface of the chair plate, and two ends of the support rod are connected to the second upper end part of the cross-folding support frame. The invention realizes folding of the folding chair by the slippage of the support rod under the chair plate, and the bearable force of the folding chair is greatly improved, thus improving the stability of the folding chair.

Description

technical field [0001] The invention relates to a chair, in particular to a folding chair and a folding chair with armrests. Background technique [0002] The traditional folding chair is folded through the front leg, the rear leg, the seat frame support rod and a connecting piece to form a four-bar linkage mechanism. The rear leg is shorter than the front leg, and its top is pivotally connected to the rear leg. In the upper middle position, the middle rear position of the seat frame support rod is pivotally connected with the middle position of the front chair leg, and the near rear end position of the seat frame support rod is pivotally connected with one end of the connecting piece, and the other end of the connecting piece is connected with the The position near the upper end of the rear chair leg is pivotally connected. When the folding chair is fully opened, the seat plate is fixed horizontally by using the connecting piece against the protrusion provided on one side ...
