Abstract

The utility model discloses a multi-functional chair, belonging to the field of furniture. The multi-functional chair is an improvement over the prior art. The utility model is adopted a main frame and a backrest frame to form the main body of the multi-functional chair. The main frame and the backrest frame are connected via a pin. The deformation of a chair, a comfortable chair and a ladder chair can be formed by the connection of the different positions of the main frame and the backrest frame. A seat cushion can be assembled with the main frame and the backrest to form the whole body of the multi-functional chair. Thus, the multi-functional chair has multi purposes, and the utility model can be used with the function of single furniture.

Description

Multifunctional chair

The utility model is a kind of furniture.

The utility model multi-functional chair is the improvement to existing chair.No matter present existing chair is wooden or fixedly chair, the folding seat of steel, and the height of its seat cushion generally is a kind of height of fixing, can not become comfortable chair at an easy rate and use, and more cannot work as the ladder chair and be used to support the human body use of ascending a height.Therefore, the function singleness of traditional chair, purposes is restricted.To these deficiencies of conventional chair, the utility model is given to solve technically preferably.

Task of the present utility model is a kind of multi-functional chair that has two kinds of bench heights, can be deformed into comfortable chair and ladder chair of design.

Figure of description 1 is a multi-functional chair agent structure schematic diagram.1 main frame among the figure, 2 seat back frames, back rest on 3,4 times back rests, 5 detachable hinges, 6,7 bolts, 8,9,10,11 bearing pins,

Figure of description 2 is multi-functional chair agent structure schematic diagrames when being deformed into the ladder chair.8,9,10,11 bearing pins among the figure.

Figure of description 3 is multi-functional chair agent structure schematic diagrames when being deformed into comfortable chair.

Figure of description 4 is overall structure schematic diagrames of bearing pin.

Figure of description 5 is overall schematic of multi-functional chair.

Main points of the present utility model are that the main part of chair is made up of main frame and seat back frame, seat back frame connects to the chair main body in the inboard of main frame with pin, the distortion that the binding of employing different parts can make multi-functional chair produce conventional chair---Comfortable chair---ladder chair is to reach multiplex purpose. Back rest on main frame has has lower back rest on the seat back frame, can install backrest on the back rest up and down. Seat cushion can be placed on the horizontal gird of main frame or seat back frame, and the seat cushion of multi-functional chair can be laid between differing heights, thereby all finishes invention task of the present utility model.

Now the utility model multi-functional chair is done necessary explanation according to Figure of description, in the hope of further disclosing design concept of the present utility model:

Shown in Figure of description 1, the agent structure of multi-functional chair comprises main frame 1, seat back frame 2, main frame is that three 90 degree of U type pipe both sides symmetric curvature dihedral becomes the chair shape, seat back frame is that symmetric curvature 90 degree dihedrals in U type pipe both sides become L shaped shape, main frame openend has last back rest 3 by bolt 6,7 itself and main frame to be constituted the binding of living, and seat back frame one end is fixed with down back rest 4.Be connected by detachable hinge between seat back frame and the last back rest, seat back frame and main frame intersection have four pairs of holes to be connected by

bearing pin

8,9,10,11 respectively.Backing cushion about last back rest and following back rest are pegged graft is laid seat cushion on the horizontal gird of main frame or seat back frame, and then multi-functional chair becomes the global shape shown in Figure of description 5.

Agent structure when multi-functional chair is deformed into the ladder chair is shown in Figure of description 2, main frame 1 does not change user mode, seat back frame 2 overlaps to moving to main frame horizontal gird toward the front upper place, at this moment detachable hinge 5 will be gone up the rotation of back rest tractive and be horizontal level, and main frame and seat back frame overlap the position has four pairs of holes to be connected by bearing

8,9,10,11.Seat cushion is placed in forms seat cushion on the horizontal gird---following back rest---goes up the multistage ladder structure of back rest, can be used for ascending a height and get the usefulness of thing operation.The seat cushion of this multi-functional chair and backing cushion all have base plate and elastomeric flexible pad to constitute, and U type spring bayonet socket is installed below base plate, can directly be stuck on the tubular structure of chair main body, play fixation.

When multi-functional chair is deformed into comfortable chair, dismantle detachable hinge 5, with seat back frame upset put upside down on the ground with main frame under the vertical position infall two pairs of holes are arranged, with bearing pin it is linked firmly, to descend the counter usefulness that can put leg on the back rest as comfortable chair, seat cushion and the last backing cushion invariant position of being placed on down of backing cushion.The structure of detachable hinge 5 is that U shaped steel sheet opening part has pair of holes, with a pin both sides polyphone is constituted, and pulls down pin and gets final product hinge-opening.

Outstanding advantages of the present utility model is one-object-many-purposes, can give full play to the effect of single-piece furniture, and especially seat cushion riding position difference can produce the result of use of sofa handrail chair and couch, also has the effect of Comfortable chair and ladder chair concurrently.

The embodiment of multi-functional chair is more, generally can adopt crooked plating of garden or square steel tube to make main part, also can adopt the manufacturing of engineering plastics tubing, and bearing pin is generally made with metal material, and the structure of seat cushion can adopt general common kind, repeats no more.

Claims

1, a kind of multi-functional chair, comprise seat cushion, backing cushion, it is characterized in that main frame 1 and seat back frame 2 composition chair main parts, but it is connected to one by demolition hinge 5 and bearing pin 8,9,10,11, there is nut 6,7 main frame 1 upper end the binding alive of last back rest 3 and its formation, is fixed with down back rest 4 on the seat back frame 2.
