Description

A kind of flexible thing to sit on backrest conjunction

Technical field

The utility model relates to the coupling apparatus of a kind of thing to sit on backrest and back rest, particularly about the coupling apparatus of flexible thing to sit on backrest and back rest, belongs to furniture and makes the field.

Background technology

Raising along with living standards of the people, requirement to thing to sit on is also more and more higher, for meeting the needs of, the thing to sit on kind of manufacturer's exploitation is also more and more, wherein the use of chair is extensive especially, people at home, office etc. all be unable to do without chair, the personage of office particularly, be sitting on the chair for a long time, requirement to chair is very high, its chair back of traditional chair generally all is whole, and its angle is fixed, different people takes that it is stressed different, human body sensory is uncomfortable, adaptability is relatively poor, be easy to generate fatigue after long-term the seat even pathology takes place, therefore, develop a kind of simple in structure, economical and practical, use comfortable chair, particularly the chair back has the chair of adaptation function, it is the target that the thing to sit on industry is constantly pursued always, a kind of chair (2006201087427) that has flexible backrest of utility model patent that the inventor has applied for and obtained the authorization, this chair people takes the back according to the different positions and the situation of exerting oneself, and the chair back can have adaptivity to tilting to adapt to the back situation of human body all around, use as snug as a bug in a rug, but on this structure chair back is connected with chair back rack by a common spring, this connection stability is relatively poor, and elasticity should not be grasped, how to improve flexible chair one and improve performance, reducing cost is the problem that the industry is being studied always.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, develops a kind of conjunction that is used for flexible chair to improve the serviceability of flexible chair, requires to have comfortable advantage simple in structure, economical and practical, safe in utilization.

The purpose of this utility model is realized by following technical scheme.

A kind of flexible thing to sit on backrest conjunction of the utility model, make by having very the elastomeric material of strong elasticity and structural strength, comprise a pedestal and some elastic arms that extend to even distribution all around, be inlaid with a swivel nut with rigidity in the centre of pedestal, buriedly in the end of elastic arm be inlaid with a sleeve pipe with rigidity, the centre of sleeve pipe offers a through hole, be used for and being connected of the chair back, also a centring ring can be set in through hole, its end of imbedding elastomeric material inside has an outside boss, forms a counterbore.

During use, at fixing some double-screw bolts in the back of thing to sit on backrest or screens pin, double-screw bolt inserts among the through hole of elastic arm end accordingly and with a nut elastic arm and the chair back is fixed together, the screens pin firmly inserts and has among the through hole of centring ring, make the screens circle cross centring ring, rely on the interlock of centring ring and screens circle that elastic arm and thing to sit on backrest are fixed together, then the screw on the pedestal is aimed at the installing hole on the thing to sit on back rest, pass installing hole with a bolt that has knob and be screwed into screw, make conjunction and thing to sit on back rest closely fixing.Like this, the chair back is supported by equally distributed some elastic arms, identical in all directions upper support power, more stable, because all directions are stressed evenly, it is also pleasant above human body back leans against, with having very strong elasticity and the elastomeric material of structural strength such as rubber has some elastic arms by the mould one-shot forming conjunction, it generally is 3 to 5, when moulding, put into swivel nut and the sleeve pipe made with metal or duroplasts in advance, technology is very simple, therefore, the utlity model has comfortable advantage simple in structure, economical and practical, safe in utilization.
