This utility model is exposed to the outside of seat plate and lower plate by the bending section with the U-shaped spring, and except that guarantee to increase its bending radius as far as possible, the Stress Control that sweep can be produced can promote its persistency simultaneously in the elasticity field simultaneously.
The chair that this utility model constitutes is untied the hook of seat plate bottom with singlehanded pull-up locking lever, because the elastic acting force of U-shaped spring can be circular-arc from face inboard, seat with the seat face of level and upspring towards the front side.About 45 degree when seat (empty) of the seat plate maximum inclination of upspringing.If when this state is taken one's seat, can relax the impact in the time of taking one's seat by the bounce of spring, make seat face maintenance level once again.By using the U-shaped spring, can not must use hinge can link lower plate and seat plate, and obtain simply and the chair with persistency structure of cracky not.
Illustrate that with reference to drawing an embodiment is as follows.
Fig. 1 is a chair overall perspective of the present utility model.
Fig. 2 is the upspring side view of state of seat.
Fig. 3 wants portion's expanded view for the upspring back side of back, seat.
Fig. 4 protrudes in lower plate and the seat plate outside forward for explanation spring bending portion and in the expanded view of the lateral major part of set state.
Chair of the present utility model shown in Figure 1, it comprise body foot 1, altitude mixture control with foot 2, handrail 3, backrest 4, seat plate 5, lower plate 6, U-shaped spring 7, bending section 8, distance piece 9, stop rod 10, hook 11, handle portion 12, table material 13.
As shown in Figure 1, four body feet 1 that constitute frameworks of chair body configuration, setting height(from bottom) is regulated with foot 2 in the body outside, and inserts from the outside and to wear bolt and make it overlapping with body foot 1.Altitude mixture control with foot 2 in corresponding to body foot 1 a plurality of screws of giving a farfetched interpretation, height that can the person of being used is done for example adjusting of four-stage.Install respectively with body foot 1 in four bights of lower plate 6, and an end limit portion that utilizes bolt and nut will be plugged in the U-shaped spring 7 between seat plate 5 and 6 liang of plates of lower plate is simultaneously fixed.Utilize bolt and nut that the end limit portion of the opposite side of U-shaped spring 7 is fixed on the seat plate 5, install with locking lever 10 the side appropriate position of seat portion, and locking lever 10 can fasten with a hook 11, and under the state of untiing hook 11, utilize U-shaped spring 7 to support, make it and to fluctuate.If when using U-shaped spring 7, just needn't use coil spring and hinge, has chair simple in structure and that can use lastingly thereby form.
Obtain correct springback power for the person's of being used body weight, when using chair, need distinguish to some extent.In Fig. 3, the people that body weight is about 30 kilograms to 50 kilograms can use the example with 2 U-shaped spring 7 chairs as shown in Figure 3, and the people that body weight is about 50 kilograms to 80 kilograms then can use the chair with 3 U-shaped springs 7.
