Description

Pneumatic rod chair

Technical Field

The utility model belongs to the technical field of the activity seat, concretely relates to gas pole chair.

Background

The traditional sofa backrest is inconvenient to operate in a manual adjusting mode. Later, spring adjustment and air lever adjustment have been proposed, such as in the utility model application No. 200920117500.8, by extending and retracting the controllable air spring carried by the control member, to adjust the back of the chair. However, the above scheme still has the problems of complex structure, non-ergonomic adjustment process and inconvenient adjustment.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a gas pole chair through the reasonable gas pole position that sets up, redesigns the back of the chair molding for gas pole chair overall structure is simple compact, and accommodation process is comfortable.

The purpose of the utility model is realized like this: a gas rod chair comprises a chair seat and a chair back which are connected in a rotating manner, wherein handrail plates are arranged on two sides of the chair seat, a controllable gas spring for adjusting the rotating connection of the chair back is mounted at the bottom of the chair seat, a framework is supported below the seat surface of the chair seat, the tail part of a cylinder body of the controllable gas spring is hinged to the upper part of the framework, and a rod body of the controllable gas spring is connected to the lower end of the lower part of the chair back in a; the middle part of the chair back is hinged on the framework; the control part of the controllable gas spring is arranged on the side surface of the chair seat and is connected with the controllable gas spring through a pipeline; two sides of the upper part of the chair back are provided with curled edges towards the direction of the chair seat, and the back side of the chair is provided with a notch; the lower part of the turned edge is provided with a butting section which is abutted against the notch, and the middle part of the turned edge is recessed inwards to form an arm groove; the handrail plate is provided with a hand buckling groove and is arranged on the same side as the control part.

Further, the curled edge is arched outwards.

Further, the side wall of the notch is obliquely arranged towards the front side.

Furthermore, the back of the wall groove is provided with a drawable or turnable arm plate.

Furthermore, the top of the front side of the armrest plate is concave.

Further, the top surface of the handrail plate inclines backwards and obliquely downwards.

Compared with the prior art, the utility model outstanding and profitable technological effect is: the controllable gas spring is directly connected with the framework and the chair back, so that a middle connecting rod structure is omitted, and the chair is simpler and more compact; the curled edge of the chair back is embedded into the armrest plate, so that the depth of the seat surface is reduced; meanwhile, the arm groove is formed in the chair back, when the control part is broken off by hands, the large arm of a human body can be matched in the arm groove, and the adjusting process is more comfortable; the hand-clasping groove is formed in the armrest plate on the other side, so that the hand holding effect can be achieved when the angle of the chair back is adjusted backwards to be large, and the body imbalance of the other hand in the process of adjusting the control component is avoided.

Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

A gas-rod chair is combined with figures 1 and 4 and comprises a chair seat 2 and a chair back 1 which are connected in a rotating way, wherein two sides of the chair seat 2 are provided with armrest plates 2b, the bottom of the chair seat 2 is provided with a controllable gas spring 6 which is used for adjusting the chair back 1 to be connected in a rotating way, and a control part 3 of the controllable gas spring 6 is arranged on the side surface of the chair seat 2; a framework 4 is supported below the seat surface 2a of the seat 2; the middle part of the chair back 1 is hinged on the framework 4, the lower part of the chair back 1 extends downwards to form a straight plate, and two sides of the upper part of the chair back 1 are turned towards the armrest plate 2b and form a curled edge 7 with a certain radian. Correspondingly, the back side of the chair back 1 is provided with a corresponding notch 2b3, the lower part of the curled edge 7 is provided with an interference section 7a abutting against the notch 2b3, and the side walls of the interference section 7a and the notch 2b3 are inclined forwards and inclined obliquely so as to be more stable in interference.

Referring to fig. 2, an arm groove 7b is formed in the middle of the curl 7 so as to be recessed, and an outer arcuate portion 7c is formed in the upper portion of the curl 7 so as to be arcuate; when the control part 3 is broken off by hands, the big arm of the human body can be matched in the arm groove 7b, so that the adjusting process is more comfortable; meanwhile, the hand buckling groove 2b1 is formed in the upper surface of the armrest plate 2b on the other side, so that when a rider breaks the control component 3 with the hand, the other hand can be buckled in the hand buckling groove 2b1 on the right side, and the stability of the whole body is ensured, especially when the backward angle of the chair back 1 is large. The outer arch portion 7c serves to block light from the side when the human body lies. Preferably, the front top of the handrail plate 2b is recessed to form an inner recessed portion 2b2, and the top surface of the handrail plate 2b is inclined downward in a rearward direction. So set up, the better seat of personnel's both hands dependence handrail board 2b of conveniently lying.

Referring to fig. 4 specifically, the tail of the cylinder body of the controllable gas spring 6 is hinged on the upper part of the framework 4, and the rod body of the controllable gas spring 6 is obliquely downwards connected to the lower end of the lower part of the chair back 1; the control part 3 is connected with a controllable gas spring 6 through a pipeline.

Furthermore, the wall groove 7b is provided with a wall plate 5 at the back, which can be pulled or turned, and the wall plate 5 can be installed by embedding the wall plate in the chair back 1, for example, the chair back 1 is provided with a notch, and the wall plate is pulled by installing a sliding rail. After the chair back 1 is laid backwards, the inner side space is limited due to the arrangement of the turned edge 7 of the chair back 1, and hands are placed more restrictedly; at the moment, the big arm extends out through the arm groove 7b and is supported by the wall plate 5, so that the whole person is in a big-character lying posture and is more comfortable.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
