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
The present invention relates to field of furniture, in particular a kind of Foldable chair.
Background technology
Current known folding class chair, the old-fashioned bridge structure of chair greatly mainly with four-bar linkage structure is source; Or the chair for fishing of foundation eight bar linkage structures is source; And with the various folding seat that the Chair structure of place's band back angular adjustment shelves below handrail derives for source.Wherein the old-fashioned bridge structure of chair of four-bar linkage structure is simple, but amounts to volume ratio comparatively greatly, and higher to leg pipe force request, weight is also heavier; The fishing chair relative complex of eight bar linkage structures, amounts to volume smaller, and weight is also relatively light, but outward appearance by structure limit more serious; The adjustable this kind of folding seat in armrests place, amounts to volume relatively large, and weight is also relatively heavier, but accessory is more and higher to the requirement meeting of leg pipe, and cost is also relatively high.
Summary of the invention
The object of the invention is to solve the problems of the technologies described above, a kind of Foldable chair be provided, this chair quality is light, structure is simple, amount to after volume little, and good looking appearance.
For achieving the above object, technical solution of the present invention is: a kind of Foldable chair, comprise seat framework, seat back frame, front carriage and posterior bracket, described seat framework is provided with a pair curb girder and a crossbeam, described seat back frame is provided with a pair vertical beam, the outside front ends of the curb girder of described front carriage and seat framework is hinged, the front end of described vertical beam is provided with oblique angle clamping joint, described oblique angle clamping joint is provided with the first blocked hole and the second blocked hole, the upper end of described posterior bracket is provided with oblique angle gland, described oblique angle gland offers the holddown groove for inserting oblique angle clamping joint, the both sides of described holddown groove all offer fixing hole and lower fixed hole, first blocked hole of described oblique angle clamping joint and the upper fixing hole of oblique angle gland by bearing pin and side rail inner hinged, L shape contiguous block is provided with between described vertical beam and posterior bracket, so the two ends of L shape contiguous block are provided with the first connecting hole and the second connecting hole, the both sides of described oblique angle clamping joint are equipped with sliding shoe, the two ends of described sliding shoe are provided with the first through hole and the second through hole, second blocked hole of described first through hole and oblique angle clamping joint passes through pinned connection, described second through hole and the first connecting hole pass through pinned connection, the lower fixed hole of described second connecting hole and oblique angle gland by bearing pin and side rail inner hinged.
Preferably, described posterior bracket and oblique angle gland are structure as a whole.
Preferably, the oblique angle between described posterior bracket and oblique angle gland is 120 ° to 150 °.
Preferably, described vertical beam and oblique angle clamping joint are structure as a whole.
Preferably, the oblique angle between described vertical beam and oblique angle clamping joint is 120 ° to 150 °.
Preferably, above two curb girders of described seat framework, be provided with two arm-rest frames, one end of described two arm-rest frames and the outside of vertical beam hinged, the outside of its other end and front carriage is hinged.
By adopting above-mentioned technical scheme, the invention has the beneficial effects as follows: the present invention can reduce the small product size after folding, and alleviates the weight of product, very low to outward appearance restriction, the variation of profile can be realized.
