Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wheelchair apparatus capable of separating a chair portion and a wheel portion,

The present invention relates to a wheelchair apparatus, and more particularly, to a chair apparatus having a structure in which a chair section and a wheel section are easily separated when a chair is normally used as a wheelchair and movement management through a vehicle is required, And a wheelchair unit capable of separating the wheel unit.

Generally, a wheelchair is a wheeled chair that can be used when a disabled person or an elderly person with an uncomfortable leg or an uncomfortable and uncomfortable patient moves. Such a wheelchair may be constructed of a manual type that drives the wheels by gravity and an electric type that drives the wheels by using a transmission device. Generally, an electric wheelchair is used as a convenience for utilizing the rotational force of an electric motor without depending on manpower. However, it is an integral structure that is large in weight and bulky and can not be separated easily by a user. There were many difficulties. In addition, in the case of a manual wheelchair, since the wheelchair is generally integrally formed, there is a problem that it takes up a lot of space when it is stored or stored in a vehicle.

In order to solve this problem, a folding wheelchair has been developed and used. However, the conventional folding wheelchair is not often used because of the frequent breakdown and inconvenience of use, There are many restrictions on the use. In particular, since the conventional folding wheelchair is formed such that both the driving wheel and the auxiliary wheel are integrally fixed to the frame, even when the X-shaped central frame is folded when the wheelchair is not in use, only the width thereof is reduced, The volume becomes larger. Furthermore, since the wheels can not be separated from each other, it is often impossible to pass through the narrow doors. In many cases, it is difficult to carry or store the wheels because the wheels can not be stored in a narrow space. In addition, since the wheelchair is not used for a long time when the wheelchair is ridden on a vehicle, it must be stored in the trunk of the vehicle. In this case, when the wheelchair is folded, So that it is difficult to carry and store the wheelchair.

The present invention has been proposed in order to solve the above-mentioned problems of the previously proposed methods, and it is possible to detachably fasten and separate the wheel part, the chair part, the foot part and the handle part of the wheelchair device, It is possible to separate the wheel portion and the chair portion constituted by the individual unit modules and to significantly reduce the total volume when the wheelchair is normally used as a solid wheelchair and movement through the vehicle is required or storage management is required for a long time without use The object of the present invention is to provide a wheel chair device capable of separating a chair portion and a wheel portion from each other by minimizing a space occupied by the vehicle.
