Description
Technical field
The present invention relates to a kind of being installed in as the resetting means on the movable seat of seats such as activity row chair.
Background technology
In public places such as school, theater, conference hall, gymnasium, multi-media classrooms, for increasing activity space, convenient on-the-spot cleaning, rush seat mostly is the retractable row's chair of seat, the design of seat has utilized lever principle, seat is kept vertically automatically by the effect of gravity or elastic force when idle, during use by artificial down tilt seat so that take a seat.By the structure of gravity reduction, between the support 1 of seat and seat 5 resetting means is installed shown in Fig. 1 (a), wherein stop collar 2 is fixed on the inboard of support 1, and switch block 3 is fixed on the outside of turnover panel 4, and turnover panel 4 is installed in below the seat; Shown in Fig. 1 (b), switch block 3 is folded by the outer surface of revolution and stop bit plane, and the surface of revolution and stop collar 2 inwalls adapt, and the position-limiting action of stop collar 2 is born by the support end 2.11 and the positive stop end of limited block 2.1, and these two ends are the plane.After switch block 3 is embedded in the stop collar 2, can rotate in the space beyond the limited block 2.1, therefore, the movable part by switch block 3, turnover panel 4 and seat 5 constitute can overturn by the approximate centre shaft position around stop collar 2 in level and vertical scope.In the use, seat is not stressed, upset immediately, the supported end plane of limited block 2.1 is left on the stop bit plane of switch block 3, bumps the spacing plane to limited block 2.1, and contact-making surface is big when colliding, it is particularly evident when a full house (if adopt elastic reset to collide the noise that sends thus, sound is more very), the flip-flop of high-decibel makes people's agitation, the civilized atmosphere that influence is on-the-spot.Manufacturer is also updating, can the real quiet movable seat that resets but still fail to produce.
Summary of the invention
The object of the present invention is to provide and a kind ofly can make the movable seat on the seat when automatically reseting, keep quiet device for restorating sitting plate.
For achieving the above object, the present invention includes stop collar and switch block, stop collar is connected as a single entity with the limited block of inboard, and switch block is embedded in the vacancy of stop collar.Limited block has support end and positive stop end, and switch block has exert pressure accordingly end and reset terminal.Also be provided with a block in the stop collar, block one end is fixed on the positive stop end of limited block, can be to limited block deflection when the other end is stressed; The switch block reset terminal is equipped with the cushion I that protrudes in end face, also corresponding on the confined planes relative with the switch block reset terminal on the block outstanding cushion II is installed, and on the spacing end face relative with the block rear end face outstanding cushion III is installed also on the limited block.
Because the improvement of the present invention on limited block, switch block, during use, the people is pressed on the support end of limited block for the end 3.1 of exerting pressure of overturning seat until switch block, and this moment, the seat level was convenient to take a seat; In case seat is not stressed, under the reset response of gravity or elastic force, upset immediately, the end of exerting pressure of switch block bumps the positive stop end to block immediately, cushion I bump cushion II, and block slightly turns round to limited block, rear end face is collided with cushion III again, impact between switch block and limited block is disperseed step by step via " cushion mutual extrusion-block moves back changes buffering-cushion buffering ", the situation of having avoided two plane lifes to boldly confront a powerful opponent and hit, thus realized the noise reduction purpose.Experiment showed, repeatedly that through the inventor row's chair of the present invention is installed has really reached noiseless quiet effect when seat resets, can satisfy the requirement of people the well atmosphere of public audiovisual place peace and quiet, civilization.

The specific embodiment
The present invention is installed between the support and seat of seat.
Referring to Fig. 7.The present invention includes stop collar 2 and switch block 3, limited block 2.1 is connected as a single entity with stop collar 2, and switch block 3 is embedded in the vacancy of stop collar.Limited block 2.1 has a support end 2.11 and a positive stop end, 3 of the switch blocks end 3.1 and reset terminal 3.2 of correspondingly exerting pressure.
In conjunction with Fig. 2 (a) (b), Fig. 3 (a) (b), the concrete structure of each several part is described.
Shown in Fig. 2 (a), a block 2.2 is arranged, and the one end links to each other with the positive stop end of limited block 2.1, can be to limited block deflection when the other end is stressed, the rear end face of block 2.2 is the cambered surface of projection, and the space that is clipped between limited block 2.1 and the block 2.2 communicates with the vacancy of installation switch block 3.Confined planes one side at block 2.2 is provided with a groove, snaps in a cushion 6 in the groove, and part protrudes in confined planes.On the spacing end face of the limited block 2.1 relative, outstanding cushion 7 is installed also with the rear end face of block 2.2.
Shown in Fig. 3 (a), correspondence is provided with a groove on the reset terminal 3.2 of switch block 3, also snaps in a cushion 8 that protrudes in reset terminal 3.2 surfaces in the groove.
Above-mentioned cushion 6,7,8 is bar-shaped, can be silica gel stick, rubber bar etc., and above-mentioned groove is an arc-shaped surface, and some projectioies or fin also can be set in each groove, is convenient to the suffered a part of impulsive force of buffering adhesive rod.
For the embodiments of the present invention that adopt elastic reset, a torque spring shown in Figure 49 then is installed between limited block 2.1 and switch block 3, the central part with respect to stop collar extends a ring platform 2.3 on the limited block 2.1 simultaneously, limited block 2.1 has a slot 2.4 towards the inwall of ring platform, inserting of the front end 9.1 of ammunition feed spring, 9.2 of the ends of spring 9 are shored on the end 3.1 of exerting pressure of switch block 3.Exerting pressure between end 3.1 and the reset terminal 3.2 of switch block 3, surface of revolution 3.3 of relative set matches with ring platform 2.3.3.1 establish a concave station 3.4 (or groove) at the switch block end of exerting pressure, make things convenient for the placement of spring end 9.2, and can open an aperture in the appropriate location of concave station or groove, insert the terminal 9.2 bending backs of ammunition feed spring, and stabilizing spring 9 better.
Simultaneously a bearing pin is set again, encircles platform 2.3 and spring 9 is all movable is nested with on it in the fixing inboard appropriate location of the support 1 of limited block 2.1; The appropriate location of turnover panel 4 has corresponding through hole.(bearing pin and through hole also can be separately positioned on turnover panel and the support.)
The structure left-right symmetry of stop collar 2 and limited block 2.1, switch block 3 is beneficial to the installation in row's chair plate both sides.
During installation, stop collar, limited block 2.1 are fixed on the inboard of support 1, and pivot pin passes ring platform 2.3 immediately, overlap upper spring 9 again, switch block 3 is embedded in the stop collar 2, simultaneously the two ends of stabilizing spring, fix turnover panel 4 then, the resetting means of offside is also installed successively, and is at last that seat 5 is fixing.
