Abstract

The utility model relates to a backed chair that can be stored when folded, which is characterized in that: the three legs of the foldable chair are made by three pieces of board; two sideboards are respectively hinged with the two edges of a front board; a seat board is hinged with the upper end of the front board; through grooves are opened laterally on the backrest face and are cooperated through inserting with the back end face of the seat board. The utility model has the advantages that: first, a foldable chair formed by a tabular chair seat surface and a tabular chair backrest is realized, which can be formed quickly for use and can be folded overlappingly when not being used; second, the leg support of the structure of three triangles in upward view of the legs of the chair makes the stability of the chair very reliable.

Description

Foldable chair

Technical field

The utility model relates to a kind of chair of foldable for storage, belongs to chair and makes the field.

Background technology

CN2527164Y, title " a kind of folding seat ", it comprises the chair frame of both sides Armrest, backrest cloth links to each other with the chair frame, there is the folding stand of a single tine formula to be X-shaped, the folding stand lower end has crosspiece to link to each other with chair frame four pin, seat cloth is being fixed on the crosspiece in the upper end, and the middle and upper part of folding stand has two diagonal braces to link to each other with the chair frame, formation can about the chair rolled over mutually.This folding seat folds in order to realize, the seat surface of its chair and backrest are the cloth structure.

Summary of the invention

Purpose of design: design a kind of chair base surface and chair and lean against the foldable chair that is platy structure.

Design: in order to realize above-mentioned purpose of design.1, three of chair legs are made of both collapsiblely three blocks of plates, and turn again and become to look up supporting leg triangular in shape, be one of feature of the present utility model.The purpose of doing like this is: it is both rotatable that the plate of three tile height unanimities adopts hinge to be linked to be, turn again and become to look up supporting leg triangular in shape, this supporting leg not only has the characteristics of triangle stability, guarantee the stability of seat, and the time spent can not fold and reduce the place area occupied at any time.2, the backrest face laterally has groove and is grafting with the seat board rear end face and cooperates, and is two of feature of the present utility model.The purpose of doing like this is: backrest and seat board rear end face are pegged graft, the effect of back has been played on the top of its backrest, and the effect of supporting leg is played in the bottom of backrest, and looks up with three chair legs that plate constituted and to be three triangular support faces, and its stability is more reliable.Its technical scheme: three legs of foldable chair are made of three blocks of plates, and biside plate is hinged with the header board both sides respectively, and seat board and header board upper end are hinged, and the backrest face laterally has groove and is grafting with the seat board rear end face and cooperates.

The utility model is compared with background technology, and the one, realized the foldable chair that constitutes by tabular chair base surface and tabular back, the time spent can rapid shaping, and the time spent can not put by overlapped folding again; The 2nd, because looking up the leg that is three triangular structures, supports the leg of chair, make that stablizing of seat is very reliable.

Description of drawings

Fig. 1 is the structural representation of foldable chair.

The specific embodiment

Embodiment 1: with reference to accompanying drawing 1.Foldable chair, on structural design, three legs of chair are made of three blocks of plates, biside plate 5 adopts hinge 4 hinged with header board 3 both sides respectively, seat board 2 adopts hinge 4 hinged with the header board upper end, 1 on backrest laterally has groove and is grafting with seat board 2 rear end faces and cooperates, the effect of back has been played on the top of its backrest, and the effect of supporting leg is played in the bottom of backrest, that is to say, after backrest and seat board were pegged graft, the lower surface of the lower surface of its backrest and three blocks of plates was same plane, backrest 1 trapezoidal plate and up-narrow and down-wide.

What need understand is: though the foregoing description is to the utility model detailed explanation of contrasting; but these explanations; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
