Novel folding chair

Abstract

The invention relates to a novel folding chair. The novel folding chair comprises a chair seat frame, a chair back frame, a front support and a rear support. The chair seat frame is provided with a pair of side beams and a transverse beam. The chair back frame is provided with a pair of vertical beams. The front support is hinged to the front ends of the outer sides of the side beams of the chair seat frame. Oblique angle clamping heads are arranged at the front ends of the vertical beams. Oblique angle fixing heads are arranged at the upper end of the rear support, fixing grooves used for allowing the oblique angle clamping heads to be inserted therein are formed in the oblique angle fixing heads, and the oblique angle clamping heads and the oblique angle fixing heads are hinged to the inner sides of the side beams. L-shaped connecting blocks are arranged between the vertical beams and the rear support. Sliding blocks are arranged on the two sides of each oblique angle clamping head, the sliding blocks are connected with the oblique angle clamping heads through pin shafts, and the L-shaped connecting blocks and the oblique angle fixing heads are hinged to the inner sides of the side beams. By the adoption of the novel folding chair, the size of the folded product can be decreased, the weight of the product can be lowered, the appearance cannot be greatly restricted, and the diversity of the appearance can be achieved.

Description

technical field [0001] The invention relates to the field of furniture, in particular to a novel folding chair. Background technique [0002] Currently known folding chairs are mostly based on the old-fashioned bridge chair structure with four-link structure; or fishing chairs based on eight-link structure; and derived from the chair structure with back angle adjustment gear under the armrest All kinds of folding chairs. Among them, the old-fashioned bridge chair with four-link structure is simple in structure, but it is relatively large in volume when folded, and requires relatively high force on the leg tube, and the weight is relatively heavy; the fishing chair with eight-link structure is relatively complicated in structure, and its volume is relatively small when folded. The weight is also relatively light, but the appearance is severely restricted by the structure; this type of folding chair with adjustable armrests is relatively large in size and heavy in weight when...

Problems solved by technology

Among them, the old-fashioned bridge chair with four-link structure is simple in structure, but it is relatively large in volume when folded, and requires relatively high force on the leg tube, and the weight is relatively heavy; the fishing chair with eight-link structure is relatively complicated in structure, and its volume is relatively small when folded. The weight is also relatively light, but the appearance is severely restricted by the structure; this type of folding chair with adjustable armrests is relatively large in size and heavy in weight when folded, but there are many accessories and the requirements for the leg tube will be lower. Relatively high, the cost is relatively high
