Description

A kind of chair

Technical field

The utility model relates to a kind of chair, relates in particular to a kind of adjustable chair.

Background technology

Chair is a kind of backed thing to sit on, the chair back also often is used for hanging up clothing by the user when the user sits down, but the height of the conventional chair back and width often can not well support large-sized clothes, and clothes can mop floor, and therefore need a kind of adjustable chair of design to satisfy the demand.

The utility model content

The invention provides a kind of chair for addressing the above problem, its back height can be regulated and use for a long time regulating action can not lose efficacy, and Chair structure of the present utility model is simple, good positioning effect.

The technical scheme that achieves the above object is as follows:

A kind of chair, it comprises:

Backrest, its upper end open, described backrest has mounting groove, and the surface of described mounting groove has at least one groove;

Seat support;

The chair leg;

The upper chair back comprises cross bar, vertical pole, and described cross bar is vertical with vertical pole, and described cross bar has the hole of penetrating;

Carriage release lever has projection, and an end of described carriage release lever has button, and the end of the other end and described vertical pole is hinged;

Flexible member connects described vertical pole and described carriage release lever;

Described button passes the described hole that penetrates, and described vertical pole, described carriage release lever insert in the mounting groove of described backrest, and described cross bar arrives on described backrest, described projection and described groove fit during the location.

Selectable, described vertical pole both sides have two bracing pieces.

Selectable, described flexible member is spring.

Selectable, the number of described projection is at least one, and is less than or equals the number of described groove.

Selectable, the both ends of the surface of described cross bar have chute, and pull bar is placed in chute.

Selectable, described pull bar touches with described cross bar by flexible magnetic and is connected.

By carriage release lever one end and the upper chair back is hinged, the other end snaps in the hole that penetrates of the chair back, and carriage release lever and the upper chair back are combined as a whole, during the location, the projection of carriage release lever inserts the groove of chair main body and is located, and the upper chair back is adjusted to desired height, conveniently to hang up clothing.

Adopt a vertical pole and two bracing pieces to slide in backrest, in good location, avoided the upper chair back to rock, improved the bearing strength of the upper chair back, strengthen the structural stability of chair.

The flexible member that is used for the carriage release lever return adopts spring, and is simple in structure, connects compact.

The number of projection is more, and after the adjusting height, the upper chair back is more stable.

The pull bar that the cross bar two ends are set up can extend the width of the upper chair back, better hangs up large-sized clothing.

Adopt flexible magnetic to touch, simple in structure, installation and easy to use.

The specific embodiment

Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.

Fig. 1 is the profile schematic diagram of the utility model embodiment, and Fig. 2 is the profile of the utility model embodiment.As shown in Figure 1, 2, chair 1 comprises: backrest 2, seat support 7, chair leg 8, the upper chair back 3, carriage release lever 4.

As shown in Figure 2, the upper end open of backrest 2, backrest 2 has mounting groove 21, it is 4 that the surface of mounting groove 21 has at least one groove 22(figure), backrest 2 has the inclination angle, convenient leaning on, and the upper end slot that mounting groove 21 has less inclination angle and mounting groove 21 is wider than the lower end groove width.

Carriage release lever 4 has projection 41, and an end of carriage release lever 4 has button 42(referring to Fig. 3), the end of the other end and vertical pole 32 is hinged.Button 42 can be the outstanding of carriage release lever 4 upper ends, can be also the part that is fixedly connected with carriage release lever 4.Preferably, the number of projection 41 is at least one (being 2) in figure, and is less than or equals the number of groove.The number of projection is more, and after the adjusting height, the upper chair back 3 is more stable.In the present embodiment, the end of vertical pole 32 is pin joint 34, hingedly can adopt hinge, pivot pin etc.

See in conjunction with Fig. 4, the upper chair back 3 comprises cross bar 31, vertical pole 32, and cross bar 31 is vertical with vertical pole 32, and cross bar 31 has the hole of penetrating 35.Preferably, the vertical pole both sides have two bracing pieces.Mounting groove 21 is positioned at the centre of backrest 2, and vertical pole 32 is positioned at the centre of the chair back 3, and the two ends of the upper chair back 3 are symmetrically distributed with two bracing pieces 33 and insert in the chute corresponding with backrest 2.Those of ordinary skills can easily imagine, mounting groove 21 can vertically distribute in the optional position of backrest 2, but in the middle of backrest 2, make the rear Stability Analysis of Structures of the upper chair back 3 of packing into.The vertical pole 32 of the upper chair back 3 can be that width dimensions is less than any bar of backrest 2 width, in the present embodiment, symmetrical two bracing pieces 33 in cross bar 31 two ends of the preferred upper chair back 3 insert in vertical chute of backrest 2 increases, increased the overall construction intensity of the upper chair back 3, avoid the upper chair back 3 to rock, improved the bearing strength of the upper chair back 3.The cross sectional shape of cross bar 31, vertical pole 32 can be the arbitrary shapes such as triangle, circle, rectangle, square.
