The utility model relates to a kind of seat, relates in particular to a kind of seat of assisting the elderly or lower limb function reduction crowd to stand of being used to.
Background technology
At present, the chair legs of its seat of the seat on the market and seat body in vertical state and be fixed together, promptly seat and ground are in the state of opposing parallel all the time.The elderly's legs and feet are not too nimble, be sitting in very difficult when needs are stood on the chair, very the effort; When sitting down, also need shank firmly to support and just can sit down, not only the pain of requiring great effort and can aggravate shank.And also having similar problem for lower limb function reduction crowd, the quite difficulty that stands and sit down all need help just can finish the process of sitting down and standing by external force, has brought a lot of inconvenience for so daily daily life life.Therefore, use present seat very inconvenient concerning the elderly and lower limb function reduction crowd.
The utility model content
The purpose of this utility model is to provide a kind of easy to use can assist the seat of standing.
To achieve these goals, the purpose of this utility model is to provide a kind of auxiliary station stand chair, comprise seat, the front end of seat and seat body are rotated and are assembled together, the seat bottom surface is provided with a resilient supporting unit, one end of resilient supporting unit and the bottom surface of seat hinge are fitted together, and the other end is fitted together with the support bar hinge that is fixed on the seat body supporting leg.
Described resilient supporting unit is a gas spring.
The joystick of described gas spring is arranged on framework one side of seat body.
The leading section of described seat is fitted together with the corresponding framework hinge of seat body.
The leading section of described seat and the framework of seat body are fitted together by connecting rod hinge, and an end of connecting rod is fixed on the seat, the other end by hinge assemblies on the corresponding framework of seat body.
The leading section of described seat and the framework of seat body are assembled together by hinge.
Described seat body is provided with handrail.
Chair surface of the present utility model and seat body are rotated and are assembled together, resilient supporting unit can drive seat and tilt to move upward, and adjusts user's sitting posture and center of gravity, reduces the bracing force of lower limb, take advantage of a situation to assist and realize stance, finish the conversion that human body moves from the sitting posture to the stance.When needs are sat down, human body gravity and resilient supporting unit are that the resistance of gas spring reaches partial equilibrium, thereby have reduced the strength of lower limb body support deadweight, and the user is slowly sat down reposefully, alleviate exerting oneself of shank, can alleviate the pain of shank.After the user is seated, joystick is pulled locked position, gas spring is with stop motion, and seat keeps the horizontal fixed invariant position.When the user wants to stand, move the joystick of gas spring gently, open gas spring, under the effect of gas spring thrust, drive seat and tilt to move upward.The utility model can help the elderly or other lower limb functions reduction crowd to finish daily daily life life independently, easily, has brought very big convenience for people's life; Armchair structure of the present utility model is simple, and volume is little, and is in light weight, safety and stability, and do not need driven by power, its cost is very low, can move everywhere, is easy to carry, and has the excellent popularization using value.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, auxiliary seat of standing of the present utility model, comprise seat 1, the front end of seat 1 and seat body 2 are rotated and are assembled together, seat 1 bottom surface is provided with a resilient supporting unit, the resilient supporting unit of present embodiment is a gas spring 3, and an end of gas spring 3 and the bottom surface of seat 1 hinge are fitted together, and the other end is fitted together with support bar 4 hinges that are fixed on seat body 2 supporting legs.The joystick 5 of gas spring 3 is arranged on framework 6 one sides of seat body.In the present embodiment, the corresponding framework of the leading section of seat 1 and seat body 2 is fitted together by a connecting rod 7 hinges, and an end of connecting rod 7 is fixed on the seat 1, the other end by hinge assemblies on the corresponding framework of seat body.Seat body 2 is provided with handrail 8.
Embodiment 2
The difference of present embodiment and embodiment 1 only is: the leading section of seat and the framework of seat body are assembled together by hinge.
When static, gas spring 3 is in the state of stretching out, and seat 1 is in the top obliquity, as shown in Figure 1.After the user takes, open the joystick 5 of gas spring 3, under the effect of human body gravity, gas spring 3 is compressed withdrawal, because the drag effect of gas spring 3 can make the user steadily sit down lentamente.After occupying stably, pin joystick 5, this moment, gas spring 3 was in retracted mode, and seat is in the lower horizontal position.
When the user wants to stand, at first open handle 5, the gas compression that gas spring 3 stores can produce thrust to seat 1, drives seat 1 by connecting rod 7 and tilts to move upward, the user is produced a thrust that makes progress, and auxiliary user finishes the conversion of action from the sitting posture to the stance.
It should be noted last that: above embodiment is only in order to explanation, and unrestricted the technical solution of the utility model, although the utility model is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the utility model, and not breaking away from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
