multipurpose wheelchair

Abstract

The invention relates to a novel multifunctional wheelchair, which comprises a wheelchair framework, a reciprocating moving conversion mechanism, a switchable overrunning clutch mechanism, a five-item chair linage mechanism, a telescopic folding and unfolding storage plate mechanism and a seat plate convenient for toilet and convenient to be cleaned, wherein the reciprocating movement conversion mechanism, the switchable overrunning clutch mechanism and a hand braking mechanism are combined for completing the linear reciprocating movement conversion of an armrest into circumferential reciprocating movement, and the circumferential reciprocating movement is further converted into the circumference movement of a synchronous belt driving wheel, so that a user can drive driving wheels of the wheelchair to do positive / reverse movement and brake only through the armrest. The simultaneous linkage of five aspects including a head cushion, a folding backrest, a back rest, a seat plate and pedals can be realized through the five-item linkage mechanism, further, the user can regulate the sitting posture at any time, the body can extend, and the sedentariness patient can favorably recover. The telescopic folding and unfolding storage plate mechanism is convenient for article placement on the wheel chair, so that the daily activities such as drinking and eating, writing and Internet surfing of the user can be more convenient and faster.

Description

technical field [0001] The invention belongs to the field of wheelchairs, in particular to a multifunctional wheelchair which is beneficial to health and facilitates going to the toilet. Background technique [0002] Current manual wheelchairs basically rely on manually driving the handwheels on both sides of the wheelchair to drive the movement of the driving wheels. It requires the user to open his arms, lean forward, and turn the handwheels. Although the transmission method of the hand wheel and the driving wheel is direct, the way for the user to turn the hand wheel is extremely inconvenient and easily fatigued. Especially when the road surface has a slope, it is even more difficult to control. Such wheelchairs are more from the perspective of convenient care, so we see that such wheelchairs are usually in a state of motion being pushed by the nursing staff. [0003] At present, the seats of wheelchairs with good quality are all designed according to the principles of ...

Problems solved by technology

From this we can see that the current design of wheelchair seats is not enough for disabled people who have to sit for a long time

Furthermore, when the user drives the wheelchair, he cannot hold items in his hand at the same time, such as water cups, etc., and this inconvenience is often encountered in daily life.

[0004] The problem of going to the toilet is often one of the key factors for the dependence of the disabled on the nursing staff. The current solution is to place a potty under the wheelchair seat, which still requires a nursing staff, and the other is to sit on a toilet chair. This approach requires the patient to switch between the two, and switching between four wheeled seats is not something that people with lower extremity disabilities can do easily and safely
