The folding chair has a simple structure, is convenient to fold, occupies a small space when folded, is convenient to store and transport, and contributes to reducing transportation cost.

Description

Folding seat

Technical field

The utility model relates to a kind of chair, particularly a kind of folding seat.

Background technology

Folding seat is conveniently moved and is saved the space and receives liking of people because of it, be specially adapted to places such as all kinds of training organizations, school and college, public place, hospital, dining room, hotel, company, family.The seat support of existing folding seat is fixedly connected with back leg, and the chair back is fixedly connected with preceding chair leg, and preceding chair leg and back leg are hinged, and promptly generally this lever chi structure of employing is drawn close seat support and back leg and folded up to the chair back and preceding chair leg.Though this lever chi structure can be folded into chair to a certain degree, inevitable shape in an angle, the saving in space amount awaits further raising; Be inconvenient to load and transport; And structure interferes with each other, and can receive outside destroy easily, so be necessary to invent a kind of folding seat of saving the space.

Summary of the invention

In view of the deficiency of prior art, the purpose of the utility model is to provide a kind of folding seat of saving the space.

To achieve these goals; The technical scheme of the utility model is: a kind of folding seat; Comprise the chair back and seat support; It is characterized in that: the said chair back extends two back legs, and rear end two connectors of said seat support are hinged with two back legs respectively, makes seat support upwards to be turned into vertical folded state from the horizontal opening state; One of them back leg is hinged with long preceding chair leg frame that can inwardly rotate 90 degree through the hyphen bar; Another back leg is hinged with short preceding chair leg frame that can inwardly rotate 90 degree through long transverse lever; Make long preceding chair leg frame and short preceding chair leg frame to fold up successively; Chair leg and the support bar that is used to place seat support before chair leg frame includes before two, an end and the back leg of said support bar are hinged, and the other end of said support bar is connected with preceding chair leg.

Further, said two preceding chair leg frames all also comprise the bracing piece that parallels with support bar, and an end and the back leg of said bracing piece are hinged, and the other end of said bracing piece is connected with preceding chair leg.

Further, the downside of said seat support is provided with and is used for the U-shaped cover that back-off is lived support bar.

Further, said U-shaped puts and is provided with the night bolt mechanism that is used to block support bar, and said night bolt mechanism comprises the latch that the stage clip that is arranged in the spring base and an end are provided with draw ring, and the other end of said latch matches with jack on the support bar.

Compared with prior art, the utlity model has following advantage: the seat support of this folding seat can upwards be turned into vertical folded state from the horizontal opening state, more presses close to the chair back; Two preceding chair leg frames can inwardly rotate 90 degree successively to be folded up, and can not produce interference; Chair structure after folding is compact, saves very much the space, and convenient collection and transportation help reducing cost of transportation.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further elaboration.

With reference to figure 1 ~ 4; A kind of folding seat comprises the chair back 1 and seat support 2, and it is characterized in that: the said chair back 1 extends two back legs 3; Said seat support 2 rear ends two connectors 4 are not hinged with two back legs 3, make seat support 2 upwards to be turned into vertical folded state from the horizontal opening state; One of them back leg 3 is hinged with long preceding chair leg frame 6 that can inwardly rotate 90 degree through hyphen bar 5; Another back leg 3 is hinged with short preceding chair leg frame 8 that can inwardly rotate 90 degree through long transverse lever 7; Make long preceding chair leg frame 6 and short preceding chair leg frame 8 to fold up successively; Chair leg 9 and the support bar 10 that is used to place seat support 2 before chair leg frame includes before two; One end and the back leg 3 of said support bar 10 are hinged, and the other end of said support bar 10 is connected with preceding chair leg 9.

In the present embodiment, said connector 4 is a lath, and an end of said connector 4 is fixedly connected on the rear end of seat support 2, can be welding or mode such as be spirally connected, the other end through bolted splice on the sidewall of back leg 3; When seat support 2 upwards is turned into vertical folded state from the horizontal opening state, seat support 2 is more pressed close to the chair back 1, saves the space.Said hyphen bar 5 all is welded on the back leg 3 with long transverse lever 7, and the support bar 10 of long preceding chair leg frame 6 is longer, and the support bar 10 of short preceding chair leg frame 8 is shorter.

In the present embodiment; In order to strengthen the structural strength of folding seat; Chair leg frame all also comprises the bracing piece 11 that parallels with support bar 10 before said two; One end and the back leg 3 of said bracing piece 11 are hinged, and the other end of said bracing piece 11 is connected with preceding chair leg 9, and its concrete syndeton is the same with the syndeton of preceding back leg with support bar 10.

In the present embodiment; Structure is more reliable and more stable when making folding seat use; The downside of said seat support 2 is provided with and is used for the U-shaped cover 12 that back-off is lived support bar 10; Said U-shaped cover 12 is provided with the night bolt mechanism that is used to block support bar 10, and said night bolt mechanism comprises the latch 16 that the stage clip 14 that is arranged in the spring base 13 and an end are provided with draw ring 15; One end of said stage clip 16 props up spring base 13, and the other end props up the other end of latch 16, makes the other end of latch 16 insert in the jack 17 on the support bar 10.

The method for folding of the utility model is following: through draw ring 15 latch 16 pulled out, and with seat support 2 90 degree that upwards overturn, will be than inside rotation 90 degree of long preceding chair leg frame 6, chair leg frame 8 that will be short inwardly rotation 90 is spent, and gets final product.

Need to prove that especially in the present embodiment, the seat support face and the chair back face of this folding seat are welded to form by a plurality of laths, but are not limited to this, can also adopt the panel of monoblock; Other bridges such as preceding back leg all adopt rectangular steel tube, firm and durable, but be not limited to this, can also be round steel pipe etc.; The bottom of preceding back leg generally can be provided with foot pad, and is not only anti-skidding, and prevents to scratch the floor.

The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
