JPH0690981A - Folding electric-motor wheelchair - Google Patents

Abstract

PURPOSE:To house a folding electric-motor wheelchair in small spaces by reducing the size in putting it away by constituting the wheel chare so as to be foldable. CONSTITUTION:Two bearings are installed on both sides of the back foot of a main frame to support a back wheel. A wiper motor is attached to the shaft of the back wheel to transmit the driving power directly. The J-type free wheel is used for two wheels. The wheel chair is constructed by a light aluminum material to fold freely. The seat and the back of the chair are covered with durable cloth. When the wheel chair is back to the chair state from being folded, the back of the chair is put inside metal fittings. As soon as the back of the chair is folded forward by the metal fittings 1, the front foot part is housed inside. A motor driving circuit and a control circuit device are placed under the seat and a control section is used on the lap of a user. A shield type without liquid leakage is desirable for a battery, which is fixed by a belt with one operation.

Detailed Description of the Invention

[Industrial application] Scope of manufacturing new wheelchairs and scope of remodeling already manufactured wheelchairs

2. Description of the Related Art A general electric wheelchair is large and needs a certain amount of space for storage. Even if it was made smaller, it had to be disassembled, at most by removing parts, and there is no wheelchair kit.

Problems to be Solved by the Invention In Japan, houses are generally small, and when a large electric wheelchair or the like is placed inside the building, it is difficult to secure a special space. An object of the present invention is to reduce the size of an electric wheelchair so that it can be stored in a narrow space such as a front door and can be easily moved by being put on a trunk of an ordinary passenger car or the like. It is also intended to be made into a kit so that people with disabilities can make it themselves.

In order to achieve the above object, a folding electric wheelchair is made possible, and when it is not used, it is made compact and stored. Also, make a wheelchair into a kit.

[Function] Since the electric wheelchair can be folded, the size when stored can be reduced. It can also be loaded in the trunk of ordinary passenger cars. Also, by making it a kit, people with disabilities can make it themselves.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, two bearings are attached to one side of the rear leg of the main body frame, and a total of four bearings are attached to the rear wheel as shown in FIG. The motors are attached so that the drive is directly transmitted to the rear wheel shafts. An automobile wiper motor was used. J-type free wheels are used for the two front wheels. The main body wheelchair is assembled from a lightweight aluminum material and has a foldable structure as shown in Fig. 2. The backrest and the seat are
A sturdy cloth was used. When the chair is turned from the folded state, the backrest is sandwiched inside the metal fitting 1 at A in FIG. 2 so that it is firmly fixed and stable as a chair. Further, in the component 1, the backrest is folded forward and the front legs are accommodated inside. The motor drive circuit and the control circuit device are placed under the seat as shown in FIG. 1B, and the operation unit is
As shown in C of FIG. 1, the user puts it on the knee and uses it. Since the battery mounting angle changes when the battery is folded, a shield type that does not leak liquid is desirable. As shown in Fig. 2D, the belt can be fixed with one touch so that it can be easily removed.

[Effects of the Invention] Since the size of an electric wheelchair can be reduced, it can be stored in a narrow space such as a front door, and can be carried by an ordinary passenger car. I can do it now. In addition, by making a wheelchair kit including an electric type,
People with disabilities will be able to make things themselves, which will increase their social significance.
