The seat of energy stair climbing, Multipurpose wheelchair for sleeping in

Technical field

This utility model relates to a kind of seat of energy stair climbing, Multipurpose wheelchair for sleeping in.

Background technology

At present, known wheelchair is on the basis of conventional chair, and wheel is installed in after-poppet (lower limb) bottom, and is equipped with hand the wheel in the wheel outside, deflecting roller is installed in fore-stock (lower limb) lower end is formed.The wheelchair of some climbing stairs ladder design in recent years, but costing an arm and a leg of having do not accepted by ordinary people, and the effect that has is undesirable, uses inconvenience, and is inapplicable.So wheelchair-bound patient thinks that upper and lower building is still a big difficulty.It also is difficult wanting to change that posture has a rest after these people sit on the wheelchair in addition, and therefore normal sense is very tired.

Summary of the invention:

In order to solve top problem, this utility model provides a kind of seat of energy stair climbing, Multipurpose wheelchair for sleeping in.The patient uses this wheelchair, not only can upper and lower easily stair under the nursing staff assists, and can easily change the angle and the whole angle of wheelchair of Wheelchair structure, patient can as required or be sat or crouch, or the posture between the two.

The technical scheme that its technical problem that solves this utility model adopts is: the fixed connection mode that becomes common wheelchair agent structure, change into and be seen as rotating axle bind mode from the side, the tetragon that forward and backward support and seat framework, handrail are formed can form within the specific limits arbitrarily angled that needs.Connect with scalable pull bar (the scalable pull bar in bottom) leading between (back) wheel shaft and the seat framework front end, increase by one group of two axle center at collinear jockey pulley in wheelchair after-poppet (backrest) back, and wheelspan is identical with the main wheel wheelspan, and the main wheel of homonymy and jockey pulley are on same plane.The jockey pulley axle connects by the axle of a framework and bull wheel is rotatable.The jockey pulley axle also uses scalable pull bar (the scalable pull bar in rear portion) to connect with the seat afterframe rotationally.Special-purpose belt-type crawler belt is installed on main and auxiliary wheel of homonymy.When the patient on being sitting in wheelchair needs stair climbing under the nursing staff assists, depress the left hand joystick earlier, wheel chair handle is pulled back again, the angle that makes front and back support and seat face is about 45 degree, decontrols this one handle.The scalable pull bar length in bottom is fixed.Then wheelchair integral body is turned over about about 15 degree, regulate the scalable pull bar in rear portion,, can begin stair climbing one side make adjusting to and stair angle consistent location of crawler belt downside with identical method; When needs of patients changes posture, depress left and right two handles simultaneously, the planar angle adjustment of forward and backward support and seat place is arrived the position that needs, and jockey pulley is landed, decontrol two handles, can keep standing state; When need upper and lower building, handling position be relatively low, makes troubles to use, and therefore, the shape of handle makes the "T"-shaped of English capitalization into by the inverted "L" shaped of English capitalization, can be convenient to upwards draw upstairs the time.

The beneficial effects of the utility model are: convenient equally with existing other wheelchair when travelling in the smooth-riding surface; Adjust to the state of needs when needing stair climbing easily, and the gravity center of human body is lower in the process of going upstairs, the patient haves a sense of security; The gravity center of human body has moved on to main wheel between the jockey pulley and near main wheel, and the nursing staff can easily pass through the hand control wheelchair; During to the platform that turns round, can and begin to climb down a flight of stairs as the light turning of flat car last again; Can be easily the structural adjustment of wheelchair angle of inclination own, can avoid the patient to be seated with same posture for a long time and the fatigue that produces; Front and back support and seat face are adjusted to smaller angle and wheelchair integral inclination angle hour, but patient's recumbency is had a rest the mobile number of times between having significantly reduced from the wheelchair to the bed.

The cross-sectional design concavity of special-purpose crawler belt, negative area is consistent with main and auxiliary tire outer rim section profile, slippage in the time of can avoiding the crawler belt transmission vertically is designed to the bending of zigzag when helping crawler belt by less jockey pulley, can reduce idle work consumption, prolong crawler belt service life.

This utility model is simple in structure,, cost is low, and is easy to use.
