Abstract

The utility model belongs to a chair, particularly a folding chair for sitting and backing. The folding chair comprises a front foldout-shaped crossbar, a back foldout-shaped crossbar and a chair backrest made of soft material, wherein, the front foldout-shaped crossbar and the back foldout-shaped crossbar are connected with the position between two chair backrest girders. Thus, the utility model can be unfolded right and left and folded. Because a bottom frame forms an arc shape, the utility model can freely swing front and back when the utility model is seated and backed. The utility model has the advantages of simple structure, convenient and comfortable use, low cost, etc., and each component is easily manufactured.

Description

Folding chair

The utility model belongs to the daily life chair, is a kind of folding seat.

Present common Collapsible seat, how two by set a roof beam in place and two side stands between attaching is folding use member, can make the gathering of seat front and back superimposed, can regulate the angle that seat support and chair lean on again.Though the type of its folding component is more, comparatively convenient in the use, exist can only before folding, folding with member deficiency such as complexity comparatively.

The purpose of this utility model be to provide a kind of can about draw superimposed folding seat in, the folding component of this folding seat is the stull that is installed between the branch of vertical portion, two side stands front and back, article two, stull is lived in selling by two flap and is connected and composed, the seat support of folding seat and chair are by being made by flexible material, articulate by beam with two seats, make this seat can about draw in superimposed to overcome the deficiencies in the prior art.

Overall structure of the present utility model is:

A kind of folding seat is leaned on frame by seat, side stand and the stull that is connected with side stand, underframe constitutes, it is characterized in that two seats by set a roof beam in place (1) respectively with a left side, right two Jiong shape side stands (2) connect with securing member, article two, seat is the pipe fitting or the rod member of curved shape by setting a roof beam in place, and the part between the side stand junction is as the curb girder of seat support, the top of two side stands and bottom are installed handrail (3) and foot pad or underframe (4) respectively, before, rear cross member (5) respectively with a left side, right two side stands connect, before, rear cross member is lived by two flap (6) and is sold the butt joint formation, seat support that flexible material is made and chair are by (7), be one whole or be divided into two sections, its end articulates by setting a roof beam in place with two seats respectively.

This chair folding component architectural feature is:

Four flap are the trapezoidal plate of middle part hollow out, the butt end of each trapezoidal flap (9) is the deflection certain angle inwardly, each flexed portion is offered the pin-and-hole (10) of grafting bearing pin, and the other end of each flap is pegged graft with the clamping plate (8) that are nested with vertical part before and after two side stands.

The architectural feature of underframe is:

The fastening connection of bottom, front and back of arcuation underframe (4) and each side stand.

Accompanying drawing of the present utility model has:

Fig. 1 is the front view of folding seat.

Fig. 2 is the side view of folding seat.

Fig. 3 is the front view of flap.

Fig. 4 is the side view of flap.

Accompanying drawing has provided embodiment of the present utility model, further specifies as follows in conjunction with the accompanying drawings:

The wide about 500-600mm of this folding seat, i.e. the spacing of two side stand beams, total length is about 1100-1400mm, and being bent into curve-like is φ 80 aluminium alloy pipe (see figure 2)s, the about 850-900mm of underframe chord length, as shown in Figure 2.Type side stand lower end spacing is 500-600mm, and high about 400-500mm both sides cantilever tip width is 200-250mm, adopts aluminium alloy φ 20 tubing.Arc underframe and handrail are wood materials and make.Seat by set a roof beam in place, the assembly relation of Jiong shape side stand, handrail, underframe and clamping plate, the stull of folding shape as shown in Figure 1 and Figure 2.Clamping plate are iron plate, each piece flap is an aluminum alloy material, the total length of every flap is about 260-300mm, and the deflection end of the grafting bearing pin angle [alpha] that bends inwards is about 120 °-130 °, offers two through holes so that be connected with clamping plate with securing member with the end that clamping plate are pegged graft.Chair adopts leather substance to make by being linked as an integral body with seat support, is articulated in two seats by between setting a roof beam in place, and draws in folding about being beneficial to.

The obtained technological progress of the utility model is:

The seat that this folding seat is made by the stull of folding shape with by flexible material by realize seat about draw in, folding, saved the folding annex of using, can freely swing front and back when matching in addition the arcuation mounting. Have the characteristics such as reasonable in design, easy to use and each member are easy to make, cost is lower.
