Abstract
A structure for regulating the inclination of the chair back is characterized in that the chair back is movably hinged with the chair, one end of a handrail is movably connected with the middle and lower part of the chair back, an arc guide rail is arranged below the handrail, one end of the guide rail is fixed on the front lower end of the handrail and the other end on a bearing foot of the chair, and the chair is provided with a guide-rail locking device. The utility model has the advantages that the structure is firm and durable and the gravity center is kept in the center of the chair when regulating the inclination of the chair back.
Description
The utility model relates to reclining chair, specifically belongs to a kind of tilt adjustments structure of the chair back.
Existing most of chair back tilt adjustments structure, be directly borrow disk manually to rotate recliner, lever operated formula recliner is adjusted, so just some problems appear: when adjusting chair back angle of inclination, the stress point of the whole chair back acts on the whole knob, because the power that stress point bore is bigger, thereby the life-span of chair back tilt adjustments structure is dwindled, and the stress point of the chair back is done the center of circle, and center of gravity is also moved backward the people is toppled over easily backward when receding.
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of firm in structure durable, and during chair back angle of inclination, center of gravity remains on the chair back tilt adjustments structure at chair center during adjustment.
For achieving the above object, the technical solution of the utility model is achieved in that the chair back and seat support are movably hinged, one end of handrail and the middle and lower part of the chair back flexibly connect, be provided with a guide rail below the handrail, guide rail is curved, one end is fixed on the preceding lower end of handrail, and the other end is fixed on the support foot of chair, and seat support is provided with guide-rail locking device.When the chair back need recede, because the chair back and seat support are movably hinged, be movably hinged with the tie point of the handrail and the chair back and do circular motion as the center of circle, be movably hinged and drive seat support simultaneously and travel forward, guide-rail locking device on the seat support also up slides on guide rail immediately, stress point when the chair back recedes like this acts on the guide rail by being movably hinged with locking device, thereby the stress point major part is dropped on the guide rail to improve the life-span of whole chair back tilt adjustments structure; Also, guarantee people's security because thereby application point acts on the center that the center of gravity that makes chair on the guide rail remains at chair, after the angle of the chair back is determined by tightening the locking device just fixedly chair back and seat support.Otherwise, just to unclamp locking device and be allowed to condition on the guide rail toward lower slider, chair back angle adjustment is just tightened the locking device fixedly chair back and seat support after well.
After adopting such scheme, because of with this tilt adjustments structure applications in the control of chair back tilt adjustments, so the utility model has following advantage: frame for movement is simple, allows user's adjustment chair back easily; Chair back tilt adjustments structure durable is strong; When the chair back was made rear-inclined, the people was difficult for falling down backward.
Below in conjunction with drawings and Examples effect of the present utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of locking device.
Fig. 3 is another structural representation of locking device.
As shown in Figure 1, the chair back 5 is movably hinged 4 with seat support 6, and an end of handrail 1 and the middle and lower part of the chair back flexibly connect 8, be provided with a guide rail 2 below the handrail 1, guide rail 2 is curved, and an end is fixed on the preceding lower end of handrail 1, the other end is fixed on the support foot 7 of chair, and seat support is provided with guide-rail locking device 3.When the chair back 5 need recede, because the chair back 5 is movably hinged with seat support 6, be movably hinged 4 and do circular motion as the center of circle with the tie point 8 of handrail 1 and the chair back 5, being movably hinged 4 drives seat support 6 simultaneously and travels forward, guide-rail locking device 3 on the seat support 6 also up slides on guide rail 2 immediately, stress point when the chair back 5 recedes like this by be movably hinged 4 and locking device 3 affact on guide rail 2, thereby the stress point major part is dropped on the guide rail 2 to improve the life-span of whole chair back tilt adjustments structure, also act on the guide rail 2 owing to application point, thereby the center of gravity that makes chair is guaranteed the security used to the center that reach remains at chair, after the angle of the chair back 5 is determined by tightening the locking device 3 just fixedly chair back 5 and seat support 6.Otherwise, just to unclamp locking device 3 and be allowed to condition on the guide rail 2 toward lower slider, the chair back 5 angle adjustment are well just tightened locking device 3, thus the fixedly chair back 5 and seat support 6.
As shown in Figure 2, locking device 3 structures comprise: knob 9, clamping 10, screw rod 11, pad 12.Locking device 3 also has other structure, and as shown in Figure 3, it comprises: knob 9, clamping 10, nut 13, screw rod 11.When needs are adjusted the angle of the chair back 5, just unclamping knob 9 slides slide lock device 3 on guide rail 2, after the angle adjustment is appropriate, just screw clamping 10 by knob 9, by clamping 10, pad 11 just directly active forces on guide rail 2, thereby locking slide lock device 3, the fixedly chair back 5 and seat support 6.The structure of locking device 3 also can be done corresponding change, describes in detail no longer one by one at this.
In the modern society of stressing exquisite life, the design of modern seat is except external form has aesthetic feeling, the fundamental that the modern especially seat of the comfortableness of seat itself, security need have, improve rear-inclined and adjust structure and not only fully take into account the lying posture requirement of ergonomics, and the safety issue of human body when considering more emphatically that life-span of chair and chair are made tilt adjustments.
