Description
Technical field
The present invention takes for the user relevant a kind of being used for, utilization is done and is had a rest or the chair tool of work etc., and the chair back of this kind of You Zhiqi chair tool is the angle of adjustable tilt, except that can be used for doing to take the most substantially, more can be used for the rest that couches, for example be used for cool chair, massage armchair etc.
Background technology
By the chair tool that generally can adjust at present chair back angle, shown in the three-dimensional exploded view of the combination of the solid of Fig. 9 and action schematic diagram and Figure 10, its seat support (10) side afterwards is provided with the chair back (11) that angle changing is adjusted in tiltable, both sides then respectively are combined with a handrail (12), this two handrail (12) rear also combines with the both sides of the chair back (11) respectively again, make and utilize this two handrail (12) but the interlock control chair back (11) pivot adjustment angle of inclination on seat support (10), and be equipped with clamping device (13) between two handrails (12) and seat support (10), when handrail (12) quilt is up cocked, can make between handrail (12) and seat support (10) and lose fixing, make handrail (12) can before and after slippage, but prerequisite two handrails (12) must be simultaneously cocked respectively, and move forward or backward simultaneously, after two handrails (12) put down simultaneously again, can fix with seat support (10) again, make the chair back (11) produce the variation at angle of inclination by this.
Above-mentioned existing structure still has the following problems point in practical application, the present invention promptly is the disappearance at this problem points, again with existing structure improvement design in addition: when its chair back (11) will be adjusted angle again, must two handrails (12) are cocked synchronously again respectively with two hands, make clamping device (13) no longer be fastened between handrail (12) and seat support (10), make handrail (12) the front and back slippage drive the variation that the chair back (11) produces the angle of inclination simultaneously, this kind structure Design is when adjusting the chair back (11), must be two handrails (12) are cocked synchronously again respectively with two hands, clamping device (13) between handrail (12) and seat support (10) is broken away from, can move and adjust the chair back (11), the occupation mode of this kind design is extremely inconvenient, especially at the inconvenient elder person of some tricks person smoothly not especially when the operation.
The present visible chair tool of adjusting the chair back, when it adjusts the chair back, all must be two handrails are cocked synchronously again respectively with two hands, clamping device between handrail and seat support is broken away from, can move and adjust the chair back, the occupation mode of this kind design is extremely inconvenient, especially is inconvenient to use for the elder person of trick inconvenience, and this must then be a technical issues that need to address points in two-handed mode.
Summary of the invention
The invention provides a kind of synchronous regulating mechanism of adjustable chair back, its seat support rear is provided with the chair back that angle changing is adjusted in tiltable, the seat support both sides then respectively are combined with adjusting lever, but adjusting lever interlock control chair back both sides, and adjusting lever is provided with clamping device, the diverse location that utilizes this clamping device can make adjusting lever adjust front and back is also fixed, when the front and back position of adjusting lever adjusts, the chair back also changes angle simultaneously, and between two adjusting levers, be combined with a synchronous connecting rod again, make when wherein the adjusting lever of a side moves, the adjusting lever of opposite side also can reach synchronization action, forms the synchronous regulating mechanism of adjustable chair back by this.
The synchronous regulating mechanism of adjustable chair back provided by the invention, when it will adjust the angle of inclination of the chair back, the user only need select one side adjusting lever the most smoothly, and the control handle that direct pull should be located, can up pivot by the interlock synchronising (connecting) rod, make the adjusting lever on this limit up be pushed away, the adjusting lever of another side is also up pushed away synchronously simultaneously, the clamping device on both sides is broken away from simultaneously, control adjusting lever on one side by this, the adjusting lever that can make both sides is synchronization action simultaneously, uses to reach the purpose that can adjust chair back angle of inclination more convenient and person smoothly in the use.
