The two bars of the rear vertical face are fully utilized in the utility model, and extend upwards to form a backrest, thereby having two purposes.

Description

The folding back chair

Technical field:

The utility model belongs to the small stores field, particularly a kind of improvement of collapsible chair.

Background technology:

A kind of collapsible disjunctor travelling chair of public offering on the existing market, its structure as shown in Figure 1, it comprises the lining 1 and the support of disjunctor, support is divided into four facades, each facade is made up of two cross one another rod members 2, hinged by upper and lower pin dish 3,4 between the rod member of each facade and adjacent facade, wherein the back facade also is provided with and is hinged on the rod member 2 of leftover bits and pieces dish 4 or two side elevations after upper foot disk 3 is passed in two backrest vertical rods, 5, two vertical rods 5 respectively; Lining 1 is fixed in respectively on two upper foot disks 3 of backrest vertical rod 5 and preceding facade.Lining 1 is to be made by seat cushion part and two of back part linings to form.This product has folding convenient, and it is little that folding plays volume, portable characteristics, the usefulness of suitable outing leisure.

Summary of the invention:

The purpose of this utility model is the folding back chair that a kind of letter of design economizes one group of intersection rod member.

Technical solutions of the utility model are achieved in that a kind of folding back chair, comprise support and the lining of propping up by bracket leg, support is divided into four facades, each facade is made up of the rod member of two mutual cross-articulation, it is characterized in that preceding facade two rod member lower ends land, the top rivet clasp has seat cushion angle dish; The facade two rod members end that closely lands before top, the end, front lower place of facade rod member was hinged on before end, two side elevation rod member front upper places was hinged on; End, the two side elevation rod member back lower places lands, the upper end, back is hinged on rivet clasp on the seat cushion angle dish on the facade rod member of back; Back facade two rod member bottoms are hinged on closely land end, top of two side elevations and pass seat cushion angle dish and extend upward the formation back-rest, are supporting the backrest lining; On the dish of facade two seat cushion angles, the rear portion was positioned on the dish of facade two seat cushion angles, back before seat cushion lining part front portion was positioned at; It is dynamically hinged that hinged between described rod member is.This structure makes full use of back facade two rod members, extends upward as backrest, kills two birds with one stone.

Seat cushion angle dish is passed in facade rod member upper end before described, and flat outward again folding constituted armrest part after elder generation up extended one section, supporting the handrail lining, and this handrail lining rear portion and backrest lining are sewed together.The facade rod member extends handrail before utilizing, and makes folding seat not only be with backrest but also have handrail, and it is lighter to be seated.

The utility model is skillfully constructed, exotic shape, and more traditional folding seat is saved two backrest rod members, and weight is lighter, under the situation that does not change function and stability, and the resource of saving rod member, assembling also is more prone to.

The specific embodiment:

With reference to Fig. 2, Fig. 3 and Fig. 5, the folding back chair, the lining 1 that includes support and propped up by bracket leg, support are divided into four facades, each facade is made up of the rod member 2 of two mutual cross-articulation, and 6 liang of rod member lower ends of preceding facade land, the top rivet clasp has seat cushion angle dish 9; 6 liang of rod members of facade end that closely lands before top, the end, front lower place of facade 6 rod members was hinged on before the end, rod member front upper place of two side elevations 7 was hinged on; End, two side elevations, the 7 rod member back lower place lands, the upper end, back is hinged on rivet clasp on the seat cushion angle dish 9 on facade 8 rod members of back; 8 liang of rod member bottoms of back facade are hinged on closely land end, top of two side elevations 7 and pass seat cushion angle dish 9 and extend upward the formation back-rest, are supporting backrest lining 11; On the facade two seat cushion angles dish 9, the rear portion was positioned on facade two seat cushion angles, the back dish 9 before seat cushion lining 12 part front portions were positioned at, and seat cushion lining 12 and backrest lining 11 fuse.

In this example, seat cushion angle dish 9 is passed in two rod members of preceding facade 6 upper end, flat outward again folding after elder generation up extends a section, constitute armrest part, supporting handrail lining 13, these handrail lining 13 rear portions and backrest lining 11 are sewed together, and perhaps adopt the sheathed facade 8 rod member upper ends, back that are positioned at.Suitably variation can be produced the chair of Armrest.

It is dynamically hinged that 2 of described rod members hinged is, wherein two on four facades to intersect the straight rivet of hinged usefulness of rod members 2 mutually hinged, hinged hinged with the right angle rivet between adjacent facade also can adopt the brace transition hinged.

With reference to Fig. 4, be the folding schematic diagram of Armrest folding back chair support, two of four facades intersect rod member 2 all can be folding around pin joint, makes support integral body to have drawn in, reduces taking up room greatly, convenient collection and transportation.
