Abstract

The utility model discloses a fitness chair whose chair back can be in stepless regulation. The fitness chair is composed of a chair back, a chair surface and a lifting chair surface support frame. The chair back comprises a chair back seat, a back cushion, rotating stems, sliding bars and components. The back cushion and the sufficient long chair back seat are respectively fetched two. The upper and the lower points of the back cushion are respectively movably connected with the corresponding upper and the corresponding lower points of the chair back seat. The upper point of the back cushion and the lower point of the chair back seat are respectively and movably connected with a root of sliding bar. The two sliding bars are sleeved together and can relatively slide. The sliding distance of the two sliding bars are regulated by nuts arranged on sliding bars. And the chair surface can also in stepless lifting so that requirements of different chair surface heights and body depths required by different people can be adapted.

Description

Fitness chair

The utility model belongs to the practicality health care seat that a kind of seat back can be regulated.

Existing seat, chair back is regulated, and just about the adjusting of gradient, can not regulate and sit deeply.

The purpose of this utility model provides the practical health care of the dark infinitely variable of a kind of seat seat.

The purpose of this utility model is to realize like this, by the chair back 1, the practicality health care seat that seat 2 and lifting seat bracing frame 3 are formed, the chair back 1 is by chair back seat 4, back cushion 5, turning handle, draw runner and other parts are formed, on back cushion and sufficiently long chair back seat, respectively get two places, on the back cushion, down on two places and chair back seat corresponding, two places flexibly connect with turning handle 6 and turning handle 7 respectively down, the following place of going up place and chair back seat of back cushion respectively is connected with draw runner 8 and draw runner 9, draw runner 8 is nested together and can slides relatively with draw runner 9, and its relative sliding distance is regulated by the nut 10 that is provided with on it.

In addition, the utility model has also solved the requirement for height of different heights to seat, its specific structural features is, lifting seat bracing frame 3 is made up of slide bar 11 and sliding sleeve 12, and sliding sleeve 12 is enclosed within on the slide bar 11 that compression spring 13 is housed, and sliding sleeve is withstood on compression spring top, the bottom is stuck on the slide bar 11, sliding sleeve is fixed on the slide bar by threaded connector, and sliding sleeve top links to each other with seat, and the slide bar bottom is as base for supporting; Lifting seat bracing frame is reinforced by ribbed pipe 15, and ribbed pipe is fixed on the threaded connector with carving to encircle by another nut.

The utility model is owing to adopted the slip of two draw runners, and the front and back that reach back cushion move up and down, thereby makes chair sit dark and the back cushion support height all changes, thereby has solved the difference seat dark requirement of different heights to seat; The utility model can also be regulated the seat height, thereby adapts to seat height and the seat dark requirement of different heights to different seats.

Below in conjunction with drawings and Examples the utility model is described in detail:

Fig. 1 looks schematic diagram for master of the present utility model.

Fig. 2 cuts open schematic diagram for A-A of the present utility model.

Fig. 3 cuts open schematic diagram for B-B of the present utility model.

Shown in Fig. 1,2 and 3, the practicality health care seat of forming by the chair back 1, seat 2 and lifting seat bracing frame 3, the chair back 1 is made up of chair back seat 4, back cushion 5, turning handle, draw runner and other parts, the C of place that goes up that goes up A of place and chair back seat 4 on the back cushion 5 links to each other with turning handle 6 two ends with 17 with rotating shaft 16 respectively, the following B of place of back cushion 5 and the following D of place of chair back seat 4 link to each other with turning handle 7 two ends with 19 with rotating shaft 18 respectively, draw runner 9 on being connected the draw runner 8 of axle on 16 and being connected axle 19 is nested and lumps together and can slide relatively, and the distance of sliding is by nut 10 adjustings that are provided with on it relatively; When unclamping nut 10, back cushion is moved forwards or backwards, then turning handle 6 and turning handle 7 17 and 19 rotate respectively around the shaft up or down, thereby then draw runner 8 and draw runner 9 respectively outwards or inwardly the seat of flexible back cushion deeply also changed, require then set bolt of position when reaching certain, nut 10, the relative size of draw runner is fixed so, then back cushion also maintains static, the height of general chair back seat is at least greater than the twice of back cushion, the same and when parallel when the length of turning handle 6 and turning handle 7, then back cushion in move or move outward and be parallel moving, the support height of back pad is moved or is moved down on then, in a word, the dark and all changes simultaneously of back cushion support height of the seat of back cushion.But the utility model also provides seat height step-less adjustment, it is finished by lifting seat bracing frame 3, lifting seat bracing frame 3 is made up of slide bar 11 and sliding sleeve 12, slide bar 11 can be a tee T, the lower end is as base for supporting, the outer compression spring 13 that is with in upper end, compression spring 13 bottoms are stuck on the slide bar 11, not slippage downwards, sliding sleeve is withstood in compression spring 13 upper ends, and sliding sleeve can slide up and down along slide bar, sliding sleeve 12 can be fixed on the slide bar by threaded connector such as nut 14, sliding sleeve top links to each other with seat, and the slide bar bottom is as base for supporting, and nut 14 adopts the interior all threaded part of external diameter, in order to reinforce bracing frame, adopt ribbed pipe to reinforce between two bracing frames, ribbed pipe 15 is by nut 22 and carve ring 23 and be fixed on the above-mentioned nut 14, and fastening nut 22 forces carves ring 23 chucking ribbed pipes 15; In the time will making the seat lifting, as long as unclamp nut 22 and carve ring, pull down ribbed pipe 15, unclamp nut 14 again, then slide under the elastic force effect of compression spring, automatically rise, when rising certain requirement height, fastening nut 14, then sliding sleeve is stable, the height of seat is also fixing, thereby adapts to different height requirements.
