The specific embodiment

Now enumerate embodiment, cooperate graphicly, structural feature of the present utility model and effect are described in detail in detail.

The seat lifting apparatus of seat provided by the utility model sees also shown in Fig. 1,2, and it is by a chair body 10, the chair plate 20 of two-chip type, and chair plate holder 30, one telescoping tube mechanisms constitute 40.The bolster 32 that this chair plate holder 30 comprises a fixed mount 31 and can supply this chair plate 20 to fix.This fixed mount 31 is to be fixed on the chair body 10, sets firmly the two horizontal bodies of rod 33 of left and right correspondence on it.The leading edge of this bolster 32 is to articulate with this fixed mount 31, and making this bolster 32 can be that the center rotates with this pivoting point 51.This bolster 32 is that 321,322 pivot joints of two parts form before and after being divided into, and making this two part 321,322 can be that warpage is made at the center with pivoting point 52.Two parts the 321, the 322nd of this bolster 32, fixing for two plate faces in front and

back

21,22 of this chair plate 20 respectively.In addition, articulate with this horizontal body of rod 33 with the back part 322 of this bolster 30 respectively with the two ends of connecting rod 34, and make the pivoting point 51 of these bolster 32 leading edges and fixed mount 31, the pivoting point 52 of this bolster 32 front and back part 321,322, the

pivoting point

53,54 at these horizontal body of rod 34 two ends forms tetragonal four summits of a flat shape.The pedestal 41 of this telescoping tube mechanism 40 and telescoping tube 42 outer ends are to articulate with the back part 322 of this bolster 32, the below cross bar 11 of chair body 10 respectively.Promote the back part 322 of this bolster 32 by this telescoping tube mechanism 40, and bolster 32, chair plate 20 are raised and moved forward, seat people thereon can be stood up easily.

When the telescoping tube 42 of telescoping tube mechanism 40 extended, this bolster 32 can be raised, as shown in Figure 3.Since aforesaid four pivoting points the 51,52,53, the 54th, the summit of formation one parallelogram, and then the back part 322 of this bolster 32 is the shape that is parallel to each other forever with this horizontal body of rod 33.So the back part 322 of this bolster 32 is horizontal forever promptly, and the old can stably be sat thereon.Therebetween, the preceding part 321 of this bolster 32 can be that rotate at the center with the pivoting point 51 of front end, and then in the process of lifting, the back part 322 of this bolster 32 has the effect that moves forward gradually, and the old is more convenient by standing up on the seat.

When reality was used, the chair back 12 places of this chair body 10 set firmly back cushion 13, were to be installed with cushion 14 on this chair plate 20, and as shown in Figure 5, this cushion 14 has bent function at the joining place of chair plate 20 forward and backward plate faces 21,22.When the old will be seated on the seat cushion 14, can be lifted to suitable height by shilling this bolster 32, make the old's buttocks rely on earlier and slightly be sitting on this cushion 14.Operate the action of contracting in telescoping tube 42 works of this telescoping tube mechanism 40 again,, the old can be sat down like a cork to reduce this bolster 32 and cushion 14 gradually.This telescoping tube mechanism 40 is known mechanism, and it mainly makes telescoping tube 42 do flexible operation by the mode of electric power motor.The telescoping tube 42 of this telescoping tube mechanism 40 must be applied to by weight and could make bolster 32 declines in the telescoping tube mechanism 40, to improve the security on using when interior contracting.The telescoping tube mechanism 40 of the passive internal withdraw type of this kind also is the technology of in the streets using already for many years.Promptly when contracting in the telescoping tube 42 of telescoping tube mechanism 40, this mechanism of flexible institute can reduce gradually to the support length of this bolster 32, and by the weight of human body and mechanism body (being bolster 32, pedestal 41) bolster 32 is depressed, make whole bolster 32 be flat condition eventually, as shown in Figure 4.In design, when contracting operation in telescoping tube 42 is done, the weight of this bolster 32 and pedestal 41 just is enough to make bolster 32 to descend.

Above-mentioned connecting rod 34 is provided with two for preferable, to obtain comparatively stable movement locus with left and right correspondence.

To sum up institute is old, the seat lifting apparatus of seat provided by the utility model, be make seat by simple connection rod set the seat in the lifting process, the ride on platform of a level can be provided, make the old more stable, laborsaving in the lifting process.In the seat lifting, can make the old move, and more convenient the old stand to seat the place ahead again.So the utility model is to be the electrodynamic type that a kind of suitableeer the old the uses chair of standing up.
