Description

Multifunction combined chair

The utility model belongs to a kind of adjustable chair, is a kind of chair that combination is decomposed of regulating specifically.

Disclosed in the prior art various adjustable chair mostly is that backrest seat face supporting leg, adjusting device constitute, and its main feature is the angle of inclination that can adjust between backrest and seat face; But rotation of seat face any direction and rotation and lifting.But also correspondingly there is a following deficiency:

1, backrest face and seat face all are machine made, for changing and keeping in repair very convenient; Moreover, the back side and seat face, soft the seat that adopts the PVC leather facing material to make causes user's contact site humidity and uncomfortable sensation can occur under hot environment.

2, the chair of said structure, the manufacturing process complexity, cost is subjected to certain restriction than higher to the scope of application.

3, function of use is more single.

The purpose of this utility model provides that a kind of adjusting is capable of being combined resolves into multiduty chair.

For achieving the above object, technical solution of the present utility model is: insert an interconvertible two-sided backrest face (1) in the groove on H type back rest is formed in perpendicular frame (3) and stull (2); Its lower end respectively is provided with a plug (4), and is in the sleeve (5) that insertion seat frame (11) is provided with below, fixing by the locking knob (6) that has on the sleeve (5); Be to insert an interconvertible two-sided seat surface (14) in the groove on the matrix seat frame (11); Each chair leg (9) bottom is respectively equipped with lift adjustment knob (10).

When being used as chair, the plug (4) of H type back rest lower end is inserted in the sleeve (5) that is fixed on seat frame (11) and spring bed (13) lower end, after adjusting the distance at backrest and seat, lock by the locking knob (6) on the sleeve (5), select as required to have with backrest face (1) and seat face (14) soft, stiff dough, insert respectively in the groove that has respectively on H type back rest and the ㄈ seat frame (11), for preventing deviating from of backrest face (1), can go up navigation button (15) by perpendicular frame (3) and limit.When being used as stool, locking knob (6) can be unclamped, make the plug (4) on the back rest break away from sleeve (5), back rest can be pulled down, and becomes a stool that does not have backrest.When needs adjustment height, the adjustment knob (10) of adjustable chair leg (9) bottom makes it to raise or reduce.

The utility model is compared technology and is had: simple in structure, and low cost of manufacture, the stool that resolves into soft, the hard back side, seat face capable of being combined also can be regulated the distance between backrest and seat, and the scope of application is wide.

Be further described below in conjunction with accompanying drawing embodiment of the present utility model:

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, be that center that spring bed (13) bottom that two ends upwarp is housed under the seat frame (11) of a ㄈ type is provided with an only pillar (7) and is connected and fixed by fixed disk (12) and spring bed (13).Solely the lower end of pillar (7) is equipped with the chair leg (9) that is cross distribution, and adjustment knob (10) is all arranged at the bottom of each chair leg (9), is used for regulating the height of chair, simultaneously; Adjustment function with level.In order to strengthen the firm and stable of chair leg (9), also on chair leg (9) and only pillar (7), a discoidal reinforcement cover (8) is set.Bottom at seat frame (11) and spring bed (13) is fixed two sleeves (5) respectively, fix by welding manner, have locking knob (6) on two sleeves (5) respectively, can be used to connect the chair frame, back rest is to be made of perpendicular frame (3) and stull (2), the lower end of two perpendicular framves (3) has plug (4), in the sleeve (5) on plug (4) the insertion seat frame (11) of back rest, is locked by locking knob (6).In the groove that the backrest face (1) of chair and seat face (14) can have respectively on the back rest of H type and ㄈ type seat frame (11), arbitrarily transposing is deviate from order to prevent backrest face (1), can be provided with two navigation buttons (15) by back rest and limit.
