Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.
Incorporated by reference to consulting Fig. 1, Fig. 2.The chair 100 of the present embodiment comprises support frame 10, left handrail 116a, right handrail 116b, seat support 114, and two controllable type air springs 120.Wherein, seat support 114 is fixed on support frame 10.Left handrail 116a is positioned at the left side of seat support 114, and right handrail 116b is positioned at the right side of seat support 114.The top of left handrail 116a and right handrail 116b can be plane roughly, or ergonomically designed shape.Axially all arranging by vertical direction of these two air springs 120, namely the stroke directions of air spring 120 is vertically arranged.The lower end of two air springs 120 is all fixed on support frame 10, and the upper end of one of them air spring 120 is fixedly connected with left handrail 116a, and the upper end of another spring 120 is fixedly connected with right handrail 116b.Wherein, the upper end of air spring 120 also can be described as free end, and lower end also can be described as stiff end.
Chair 100 also comprises controller (not shown), and the control valve of controller and air spring 120 links, for controlling the stroke of two air springs 120.In the present embodiment, controller comprises two control pieces, 121, two control pieces 121 and is arranged on correspondingly on two air springs 120, and links with the control valve of corresponding air spring 120 respectively.Particularly, in the present embodiment, control piece 121 is hands handle; In other some step examples, control piece 121 can also be the control piece of other types, such as, can also be button etc.Like this, occupant controls a control piece 121 (pull handle or press the button) respectively with two handss, then left handrail 116a and right handrail 116b can be driven to rise simultaneously, decline simultaneously by air spring 120.In some other embodiments, controller can also pass through the control valve that controlled in wireless mode (infrared control mode, Voice command mode) indirectly controls two controllers 120, to rise while controlling left handrail 116a and right handrail 116b more easily, to decline simultaneously.
Incorporated by reference to consulting Fig. 3, the level height of left handrail 116a and right handrail 116b is higher than the left handrail 116a in Fig. 2 and right handrail 116b.When left handrail 116a and right handrail 116b rise to the second using state shown in Fig. 3 from the first using state shown in Fig. 2 simultaneously time, the both arms of occupant can be supported on left handrail 116a and right handrail 116b respectively one by one, thus stand by left handrail 116a and right handrail 116b; When dropping to the first using state from the second using state while left handrail 116a and right handrail 116b, the both arms of occupant can be supported on left handrail 116a and right handrail 116b respectively one by one, thus sit down by left handrail 116a and right handrail 116b.Therefore, chair of the present utility model drives left handrail by controllable type air spring, right handrail moves up and down, and then can effectively assist the action sitting on chair and stand from chair.
More specifically, the support frame 10 of the present embodiment comprises left side to support 111a, right side to support 111b, seat support frame 112, backrest support frame 113.Left side is separately fixed at the two ends, left and right of seat support frame 112 and facing each other to support 111a and right side to support 111b.Left side has the first leg 111d to the lower end of support 111a and is positioned at the second leg 111e at the first leg 111d rear, and right side has the 3rd leg 111f to the lower end of support 111b and is positioned at the 4th leg (not shown) at the 3rd leg 111f rear.Two air springs 120 fixing is fixed on left side respectively accordingly to support 111a and right side to support 111b.
In some other embodiments, chair 100 also comprises backrest 115, and support frame 10 also comprises backrest support frame 113, and this backrest 115 is fixed on backrest support frame 113.
Preferably, left handrail 116a is also connected by a guiding mechanism between support 111a with left side.This guiding mechanism can comprise a first guide 116c and the second guide 111c.The lower end of left handrail 116a is fixedly connected with the upper end of the first guide 116c, and left side is fixedly connected with to the upper end of support 111a with the lower end of the second lead 111c.It is secondary that first guide 116c and the second guide 111c forms slide-and-guide, and the first guide 116c can slide up and down by relative second guide 111c.
Similarly, right handrail 116b is also connected by a guiding mechanism between support 111b with right side.Particularly, this guiding mechanism comprises first guide and second guide.The lower end of right handrail 116b is fixedly connected with the upper end of this first guide, and right side is fixedly connected with to the upper end of support 111b with the lower end of this second guide.It is secondary that this first guide and this second guide form slide-and-guide, and this first guide can slide up and down by this second guide relatively.
Particularly, in the present embodiment, the first guide can be a sleeve pipe, and the second guide can be a guide pillar, sleeve pipe and guide pillar phase fit.In other some embodiments, the first guide can also be made to be a guide pillar, and the second guide is a sleeve pipe, sleeve pipe and guide pillar phase fit.Or in some other embodiments, the first guide can also be made to be slide block or roller, and the second guide is guide rail, the first guide is that slide block and the second guide form guideway.
Guiding mechanism play the guiding role, especially drive in the process that stands of human body at air spring, greatly can reduce the lateral stress that loading moment produces air spring, and then the frictional force in reduction air spring between manometer tube and piston rod, and keep the effectiveness of oily air seal, and then substantially increase the service life of air spring.
Based on above explanation, those skilled in the art correctly, intactly can implement this utility model.
Should be appreciated that specific embodiment described above only in order to explain this utility model, and be not used in restriction this utility model.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
