The specific embodiment
The technology that relevant the utility model adopted, means and effect thereof, lift now that a preferred embodiment and conjunction with figs. describe in detail as after, only for the usefulness of explanation, in patent application, be not subjected to the restriction of this kind structure at this.
With reference to Fig. 1, according to first embodiment of the present utility model, the backrest of this office chair 10 and be subjected to the control of an air pressure rod and fine-tuning whole by the reclining angle of pin.
With reference to Fig. 2 and Fig. 3, this office chair 10 to include seat cushion 20, a backrest 30, that one or two lateral margins are provided with handrail 21 flexible by pin group 40, a trace 50 and an air pressure rod 60.Backrest 30 is hubbed at an end of two handrails 21.The one flexible below of being located at seat cushion 20 by pin group 40.One trace 50 is located at backrest 30 and flexible by 40 of pin groups, and interlock is flexible by 40 swings of pin group synchronously to make backrest 30.Air pressure rod 60 is hubbed at 30 on seat cushion 20 and backrest, can control the pivot pivot angle degree of backrest 30.
Two lateral margins of seat cushion 20 are respectively equipped with a handrail 21, and the below of seat cushion 20 is provided with a chair pin 22, and this seat cushion 20 is available for users to take, the comfortable storing of hand that this handrail 21 is available for users to.
Flexible is to be formed by mutually assembling by a plurality of bars 43 by pin group 40, and it includes first end 41 and second end 42, and its first end 41 is located at the end that seat cushion 20 belows differ from backrest 30, and the foot that its second end 42 is available for users to puts.
Trace 50 includes second end 32 that first end 51 and second end, 52, the first ends 51 are hubbed at backrest 30, and its second end 52 is hubbed at flexible bar 43 by pin group 40 first ends 41.
Fig. 2 further shows air pressure rod 60 under elongation state, and it is more upright by pin group 40 that the backrest 30 of office chair 10 reaches flexible.With reference to Fig. 3,,, backrest 30 also can't adjust so reaching flexible reclining angle by pin group 40 because the valve of air pressure rod 60 is not unlocked and can't stretches.
With reference to Fig. 4, when user's desire is adjusted backrest 30 and flexible reclining angle by pin group 40, can be by pulling the valve opening that action bars 61 makes air pressure rod 60.With reference to Fig. 5, user's gravity that utilizes health of can slightly swinging back is adjusted backrest 30 to suitable reclining angle, since trace 50 be hubbed at backrest 30 with flexible by 40 of pin groups, so flexible 40 meetings be driven by trace 50 and put with backrest 30 synchronous pivots by the pin group.The user only need decontrol the valve closing that action bars 61 makes air pressure rod 60, can keep backrest 30 and flexible reclining angle by pin group 40.
Fig. 5 further shows air pressure rod 60 under contraction state, and the backrest 30 of office chair 10 and the flexible pin group 40 of leaning on are to tilt.Because backrest 30 and the flexible reclining angle of pin group 40 of leaning on are controlled by air pressure rod 60, have the specific function of not having section inching so backrest 30 reaches flexible reclining angle by pin group 40, can be adjusted to the position of the best according to user's demand.
Can summarize with regard to the above and the utlity model has following advantage:
1. the office chair of lying of facing upward of the present utility model, its trace is to be hubbed at backrest and flexible by between the pin group, can be driven by trace and put by the pin group so stretch with the synchronous pivot of backrest, and backrest and the flexible reclining angle of pin group of leaning on are controlled by air pressure rod, so backrest and the flexible reclining angle of pin group of leaning on have the specific function of not having the section inching, can be adjusted to best position according to user's demand, be one to have the design of industry applications in fact.
2. the office chair of lying of facing upward of the present utility model, it utilizes an air pressure rod optionally to control backrest and flexible pivot pivot angle degree by the pin group, and is simple in structure, assembling is quick, reliability and durability, can significantly reduce producing cost, is in fact one to have the design of progressive.
The above, it only is preferred embodiment of the present utility model, when can not with the scope implemented of qualification the utility model, so the change of numerical value or displacement of equivalent elements such as, or, all should still belong to the category that the utility model patent contains according to equalization variation and modification that the utility model claim is done.
