Description

The multifunctional portable folding seat

Technical field

The utility model relates to a kind of daily life tools, particularly a kind of can be used as after folding stool, tea table, cushion or by a plurality of same specification stooles forms bed, the multifunctional portable folding seat of cabinet and bookshelf etc.

Background technology

At present, traditional chair is fixed mostly, forms by combining with parts such as backrest all-in-one-piece back leg, seat support and forelegs, has become one of indispensable apparatus in people's daily life.Because of it takes up room greatly, carry, transport and store inconvenience, so carry, the folding seat of convenient transportation arises at the historic moment.Existing folding seat adopts articulated structure mostly, utilizes folding between the chair leg, expansion, realizes the change in location between backrest and the seat support, the purpose that reaches use, carries and store.But this folding seat is subjected to its structural limitations, and purposes is single, and folding back out-of-shape is put irregularly, unstable, and institute takes up space still bigger.At the problems referred to above, the inventor once designed a kind of portable Folding chair (patent No. is 87203251), and it adopts articulated structure, will form the connecting rod of backrest, seat support, chair leg, in folding three times of the mode of turnup, reached and carried, deposits purpose easily.This folding seat junction is easily loosening, and less stable still has unsatisfactory part, and therefore, existing folding seat haves much room for improvement.

The utility model content

The purpose of this utility model provides a kind of multifunctional portable folding seat, it effectively overcomes the defective that prior art exists, reasonable in design, the junction is firm, stable, apparatus such as folding back one-tenth cushion capable of being combined, bed, cabinet and bookshelf, have the collapsed shape rule, put neatly, stablize, deposit the little advantage that takes up room.

The purpose of this utility model is achieved in that this device comprises backrest, seat support and the chair leg that is hinged together, its technical essential is: by the forward and backward chair leg of forward and backward steady brace connection, utilize forward and backward folding pull rod to be hinged on the seat support below respectively, backrest utilizes folding to be hinged on chair base rear end, and with locator card the backrest and the chair back is fixed.

The described preceding chair inboard leg spacing that is hinged on the seat support below respectively is equal to or greater than the inboard spacing of back leg.

Because the utility model is with backrest, seat support and chair leg adopt split type articulated structure, promptly form the chair leg before, before back leg passes through, back steady brace connects, before again they being utilized, back folding pull rod is hinged on the seat support below respectively and fixes, backrest utilizes folding to be hinged on chair base rear end, and the backrest and the chair back are fixed with locator card, so both it can be launched fully, forming fixed seat uses, its backrest can be rolled over backward again, being converted into stool or tea table uses, utilize a plurality of same tea table recomposition beds, use such as cabinet or bookshelf, can also it is folding fully, the composition cushion uses or is used to carry, store, transportation has varied purposes, and easy to use.This device compared with similar products, because of its reasonable in design, the junction firmly, stable, so can effectively overcome out-of-shape behind folding that prior art exists, put irregular, unstable, the bigger defective that takes up space.In addition, its folding back one-tenth cushion capable of being combined, bed, cabinet and bookshelf etc. serve many purposes.Shape comparison rule after it is folding fully, put neat, stable in transportation, when storing, deposit take up room little, pile up together after 20 folding seat of specification of the same race are folding fully, be equivalent to a space that fixed seat is shared, therefore, both be easy to carry, and be easy to transportation again, deposit.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.

Fig. 2 is the user mode schematic diagram after backrest folds.

Fig. 3 is folded into cushion or storing state schematic diagram.

The specific embodiment

Describe concrete structure of the present utility model in detail according to Fig. 1-3.This device comprises the parts such as backrest 1, seat support 7 and chair leg that are hinged together.Wherein the specification of backrest 1, seat support 7, model should be determined according to actual instructions for use, and material therefor can be made the backrest 1 or the seat support 7 of stiff dough or Soft Roll face with sheet material or other ornament materials.The chair leg adopts section bar to make preceding chair leg 9 and back leg 5, and links into an integrated entity by forward and backward steady brace 10,4.Forward and backward

chair leg

9,5 passes through hinge 11, and utilizes forward and backward folding pull rod 6,3 to be hinged on the below of seat support 7 respectively.For strengthening the support positioning action of 6,3 pairs of forward and backward

chair legs

9,5 of forward and backward folding pull rod better, the tensioning spring (not shown) can also in position be set, can guarantee that forward and backward

chair leg

9,5 launches, the location, can prevent that again forward and backward folding pull rod 6,3 from launching the back and drawing in automatically.As articulated position other positioner is set, also can establish tensioning spring at forward and backward folding pull rod 6,3.Backrest 1 utilizes folding 12 to be hinged on the rear end of seat support 7, and with locator card 2 backrest 1 and seat support 7 is fixed.If draw back locator card 2, then backrest 1 folding can be placed on the inboard of back leg 5.For thickness and the shared space behind further this folding device of minimizing, the spacing that is hinged on preceding chair leg 9 inboards of seat support 7 belows respectively can be processed into the spacing that is equal to or greater than back leg 5 inboards, so that the outside of back leg is dropped in the inboard of the preceding chair leg 9 after folding, make it exposed surface and be in the same plane.For being convenient for carrying, handle 8 can be set in the side of seat support 7.

During operation, after the utility model launched fully, as shown in Figure 1, promptly can be used as fixed seat and use; If backrest 1 is folded to the back leg place backward, as shown in Figure 2, then can be used as stool or tea table and use, also a plurality of same tea tables can be formed uses such as bed, cabinet or bookshelf; If be converted into Fig. 3 shape fully, then can be used as the cushion use or be used for storage.
