Description

Chair with the labor-saving effect of standing up

Technical field

The utility model relates to chair, is meant a kind of chair with the labor-saving effect of standing up especially.

Background technology

With regard to general armed chair, when the people above being sitting in will stand up, as propping up health with simple mode by the downward application of force of both legs, can cause sizable burden to both legs, therefore common people can support to arrive in both hands on handrail, utilize the downward application of force of both legs and both hands to prop up health more simultaneously, make the people who is seated can be comparatively laborsaving when standing up.

But people or old man for both legs strength deficiency just can't support to arrive in the application of force with both legs when standing up, stand up and can only with the hands support to arrive in handrail merely, and this mode of standing up can cause sizable burden to both hands, for the old man and be not easy to implement.Therefore just there are many chair utilizations to cooperate the structure of oil, pneumatic cylinder or motor connecting rod to be connected on the chair cushion, by the action of controlling above-mentioned member chair cushion being risen is beneficial to stand up, yet dispose the seat of this structure, not only combined member is various, complex structure, caused high price, and the aggravation of bulky, weight is unfavorable for that also general family uses.

Summary of the invention

Main purpose of the present utility model is to provide a kind of chair with the labor-saving effect of standing up, and it is comparatively laborsaving that it can allow the user stand up.

Another purpose of the present utility model is to provide a kind of chair with the labor-saving effect of standing up, and its member is comparatively simple and with low cost.

For achieving the above object, a kind of chair with the labor-saving effect of standing up provided by the utility model consists predominantly of: a seat support, have some chair pin and a bearing, and an end of chair pin firmly supports on a plane, and bearing is connected the other end of chair pin; One seat cushion, one side are articulated on the side of bearing; One buffer unit, be arranged on the bearing and with the seat cushion butt, and can produce the predetermined power that supports to seat cushion; One handrail has a ribbed insert and a slide assemblies, and ribbed insert is articulated on the bearing, and is connected with seat cushion by slide assemblies, puts by the pivot of ribbed insert and can drive seat cushion pivot pendulum simultaneously.

The specific embodiment

Now be elaborated in conjunction with preferred embodiment of the present utility model and conjunction with figs..

As Fig. 1～shown in Figure 3, be a kind of chair 100 that the utility model one preferred embodiment is provided with the labor-saving effect of standing up, it consists predominantly of a seat support 10, a chair back 20, a seat cushion 30, a handrail 40 and a buffer unit 50.

Seat support 10 has fixedly heelpiece 12 of a seat support main body 11 and.Seat support main body 11 is overlapped by the body of rod of some reservation shapes and is formed, and can define four available ends and be supported on ground chair pin 111 and extended and interconnected the bearing 112 that forms jointly by the other end of each chair pin 111.Fixedly heelpiece 12 has a heelpiece main body 121 and two buffer stoppers 122, and heelpiece main body 121 covers on bearing 112 with one end, and a side of heelpiece main body 121 also extends internally and is formed with a recess 123.Two buffer stoppers 122 are can be with soft material made and have predetermined elasticity, be separately positioned on the side of heelpiece main body 121 other ends, and a predetermined distance is apart arranged.

The chair back 20 has two connecting rods 21 and a back pad 22.Each connecting rod 21 is bearing 112 belows that are connected seat support 10 with the one end, and the other end then up extends and is connected with back pad 22, can supply human body back dependence.

Seat cushion 30, a side of the bearing 112 of one side and seat support 10 articulates, and makes seat cushion 30 articulate axle center pivot pendulum along it, and on the side that seat cushion 30 and bearing 112 articulate, also extending internally is formed with a depressed area 31 identical with recess 123 shapes.

Handrail 40 has a ribbed insert 41 and a slide assemblies 42 that is reservation shape.The two ends of ribbed insert 41 are articulated on two relative sides of bearing 112 of seat support 10, slide assemblies 42 (as Fig. 3 and Fig. 5, shown in Figure 6) has a fixture 421 and a sliding part 422, fixture 421 is fixed on the bottom surface of seat cushion 30, and be positioned on another side of seat cushion 30 and bearing 112 pivot joints, fixture 421 also is formed with the slip hole 423 of a strip.Sliding part 422 fixedly interlocking and is arranged in the slip hole 423 of fixture 421 in the middle section of ribbed insert 41, and sliding part 422 can be moved in the precalculated position in slip hole 423.

Buffer unit 50, as shown in Figure 3, be two scroll springs, be separately positioned on the bearing 112 of seat support 10, and be positioned on the same side of seat cushion 30 and bearing 112 pivot joints, and, and with the other end and bearing 112 butts, make seat cushion 30 not be subjected to external force to do the time spent and heelpiece 12 presents the state of not fitting because of the power that supports of buffer unit 50 respectively with the bottom surface butt of one end and seat cushion 30.

More than be the introduction of the utility model main member structure, then again that its occupation mode and The characteristics is as follows:

At first, when the user is sitting on the seat cushion 30, as shown in Figure 5, seat cushion 30 just can be pressed down by user's weight and pivot pendulum down, until with heelpiece 12 on buffer stopper 122 conflict, just can utilize soft buffer stopper 122 to relax the down strength of pivot pendulum of seat cushion 30,50 compressions of buffer unit this moment because of seat cushion 30 and seat support 10, and produce a predetermined back stretch, make when the user in the time will standing up, can utilize both hands that the body weight of self is applied on the ribbed insert 41, ribbed insert 41 can be reached forward down to be passed, as shown in Figure 4, thereby drive up pivot pendulum of seat cushion 30, and utilize the back stretch of buffer unit 50 to increase the up strength of pivot pendulum of seat cushion 30 simultaneously, allow the user when standing up, can utilize both hands self body weight to be converted to and ribbed insert 41 is moved down and allow the up strength of pivot pendulum of seat cushion 30, make the user can be comparatively laborsaving when standing up by ribbed insert 41.

In this special instruction, because the two pivot joint center of ribbed insert 41 and seat cushion 30 is not to be positioned on the same axle center, therefore seat cushion 30 can produce the situation that its tie point moves with ribbed insert 41 in the pivot pendulum, therefore in the present embodiment, seat cushion 30 is connected with ribbed insert 41 indirectly by slide assemblies 42, can be along with the diverse location of seat cushion 30 annexation of 41 of maintenance and ribbed inserts at any time.As shown in Figure 5, when the user is sitting on the seat cushion 30, be fixed in the sliding part 422 on the ribbed insert 41, be positioned on the slip hole 423 middle distance seat cushions 30 pivot center of oscillation positions farthest; As shown in Figure 6, when the user leaves seat cushion 30, be fixed in the sliding part 422 on the ribbed insert 41, then be positioned on the nearest position of slip hole 423 middle distance seat cushions 30 pivot center of oscillations.Promptly when seat cushion 30 pivot when pendulum up gradually, sliding part 422 just can move to nearest position in original block distance pad 30 pivot center of oscillation positions farthest gradually from slip hole 423, make ribbed insert 41 remain on the state that is connected at any time with seat cushion 30.

In addition, fixedly heelpiece of the present utility model 12 is formed with recess 123 and depressed area 31 respectively with seat cushion 30, is beneficial to handicapped people and assists to clean health by other people above being sitting in.
