Abstract

The utility model relates to a high-grade chair. The utility model is characterized in that a chair foot (4) is fixed on a bottom surface; a front and back telescopic resetting mechanism (2) of a chair seat and a spacing rotation resetting mechanism (3) of the chair seat are arranged between the chair seat (1) and the chair foot (4); a support frame (21) of the front and back telescopic resetting mechanism (2) and the chair seat (1) are fixed into integration; the spacing rotation resetting mechanism (3) is arranged below the front and back telescopic resetting mechanism (2), and the spacing rotation resetting mechanism (3) is fixed and combined with the front and back telescopic resetting mechanism (2) into integration; a rotation sleeve (32) is intercalated downwards in the hollow part of the upper part of the chair foot (4); the rotation sleeve (32) is rotatablely connected with the chair foot (4). When the utility model is used, the seat no longer need not to be moved, and therefore, the utility model has the advantages that noises caused by which the seat strikes the bottom surface can not be emitted, and people's behavior of seating and disseating is elegant and graceful.

Description

A kind of High-grade chair

The utility model relates to a kind of High-grade chair, particularly a kind of seat of can spacing rotation and moving forward and backward.

At the meeting occasion, tables and chairs are indispensable, when the participant when taking a seat, seat need be moved so that vacate enough spaces to the direction away from desk and take a seat, and after taking a seat, generally also need move forward and backward seat to be fit to individual's distance between adjusting and the desk, similar situation is also arranged when disseating, so can make noise unavoidably, perhaps, this just is the details that the people ignored in general occasion, but in the high-level meeting occasion, the VIP is (as the participant on President of the General Assembly's platform, participant of senior Negotiating Conference or the like) every act and every move all is remarkable focus, sometimes even can be to be exposed under the camera lens of video camera, therefore details also must aspire after perfection, should be quiet as much as possible, and the participant takes a seat, the action that disseats also should be graceful as much as possible generous.

The purpose of this utility model is with regard to being at the present situation of above-mentioned prior art and a kind of High-grade chair of can spacing rotation and moving forward and backward is provided.

Design of the present utility model is: High-grade chair comprises chair pin, seat support, it is characterized in that the chair pin is fixed on the bottom surface, between seat support and chair pin, be provided with the elastic resetting-mechanism and the spacing rotation resetting-mechanism of seat support, the bearing support and the seat support of elastic resetting-mechanism are fixed as one, spacing rotation resetting-mechanism is positioned under the elastic resetting-mechanism, and be fixed with one with it, its turning set then inserts downwards in the hollow part on chair pin top, is rotatably connected with the chair pin.

Compared with prior art, chair pin of the present utility model directly is fixed on the bottom surface, no longer need to move seat during use, thereby can not send the noise of seat bump bottom surface again, when needs are taken a seat or disseat, catch the chair back or handrail to move backward with hand, slightly rotate again, can vacate and vacate the space and allow the person of taking a seat easily take a seat or disseat, after person to be taken a seat took a seat or disseats, slowly loosing one's grip reversed chair to reset and reset forward again.

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, seat comprises chair pin 4, seat support 1, and chair pin 4 is fixed on the bottom surface by fot screw 5, is provided with the elastic resetting-mechanism 2 and the spacing rotation resetting-mechanism 3 of seat support 4 between seat support 1 and chair pin 4:

Elastic resetting-mechanism 2 comprises telescoping mechanism, resetting-mechanism and firm banking 24 thereof: as Fig. 2, shown in Figure 3, telescoping mechanism is made of bearing support 21, telescopic shaft 22 and cylinder body 23, telescopic shaft 22 be positioned within the cylinder body 23 and relatively cylinder body 23 do elasticly, its two ends all can be exposed to outside the cylinder body 23 and with bearing support 21 and be fixed as one; Two groups of such telescoping mechanisms have been set up in parallel in the present embodiment; Resetting-mechanism then adopts back-moving spring, is an air spring 25 in the present embodiment, also can adopt common spring certainly; Described cylinder body 23 and air spring 25 all are fixed on the base 24.

As Fig. 1, Fig. 4, shown in Figure 5, described spacing rotation resetting-mechanism 3 mainly comprises rotation seat 34, torsion spring 31, thrust ball bearing 43, be positioned at the location interstage sleeve 44 of hollow part, chair pin 4 upper end, locating shaft 41: thrust ball bearing 43 is positioned on the load-carrying frame 42 that is arranged on chair pin 5 middle parts and is enclosed within outside the locating shaft 41 that is arranged on load-carrying frame 42 central authorities, the turning set 32 that protrudes on the rotation seat 34 inserts in the chair pin 4,33 central of the rotary axle box that set within it are enclosed within outside the locating shaft 41 of chair pin simultaneously, both be precision movingly, torsion spring 31 is enclosed within outside the rotary axle box 33 of rotation seat 34, the position of chair pin 4 outside torsion spring 31 is provided with semi-cylindrical shaped location interstage sleeve 44, rotation seat 34 then is relatively set with two spring bumping posts 37 in the outside at interstage sleeve 33 two ends, correspondence described semi-cylindrical shaped location, 38, and be set side by side with clockwise limited post 36 and counterclockwise limited post 35 facing to a side of locating interstage sleeve 33; Rotation seat 34 tops then with elastic resetting-mechanism 2 in base 24 fixing.

When rotation seat 34 clockwise rotates, the following free end of torsion spring is driven and together clockwise rotates by its contiguous spring bumping post 38, the last free end of torsion spring 31 is then located stopping of interstage sleeve 44 and is spacing motionless, therefore torsion spring 31 produces screen resilience, when being subjected to locating stopping of interstage sleeve 44, the clockwise limited post 36 on the rotation seat 34 turned over maximum angle, this angle is made as 60 ° in the present embodiment, as shown in Figure 6; And when the external force of swiveling seat is removed, even the screen resilience rotation seat 34 of torsion spring 31 returns back to nature as shown in Figure 5; When rotation seat 34 rotates counterclockwise, as shown in Figure 7, the following free end of torsion spring 31 is then located stopping of interstage sleeve 44 and is spacing motionless, the last free end of torsion spring is driven and together rotates counterclockwise by its contiguous spring bumping post 37, is subjected to locating stopping of interstage sleeve 44 until the counterclockwise limited post 35 on rotation seat 34.
