Description

Wheelchairs {WHEELCHAIR}

The present invention relates to a wheelchair, and more particularly to a wheelchair in which the armrest is rotatably fixed to the frame so that the patient can easily board the vehicle.

In general, a wheelchair is a means of movement used when a patient or a handicapped person who is inconvenient to move moves relatively short distances, and the patient drives the annular drive handle attached to the wheel by magnetic force or with the help of an assistant. In addition, by connecting an electric device such as an electric motor to the wheel, an electric wheelchair has been developed that enables the patient to drive the wheel by simple switch operation.

An example of the above-described wheelchair is shown in FIG. 1, which is briefly described as follows.

As shown, the wheelchair 10 includes a frame 1 made of lightweight material.

The frame 1 includes a pair of side members 1a and 1b arranged to face each other at predetermined intervals, and an X-shaped bar 1c having a hinge for arbitrarily adjusting the distance between the side members. Include. In addition, between the side members is provided with a soft seat (2) that can be seated by the patient.

The X-shaped bar 1c maximizes the space between the side members 1a and 1b when the wheelchair is used to provide a space for the patient to sit on the seat 2, and the side member 1a when the wheelchair is not used. Minimize the space between (1b) so that the wheelchair can be stored in a narrow space.

On the outside of the side members (1a) and (1b), a wheel (3) rotating about a rotational axis is generally installed in parallel with the side member, and the wheel (3) has an annular drive handle (4) for driving it. Each is provided. In addition, a brake means (not shown) may be further included to prevent rotation of the wheel.

At the front lower side of the side member, the auxiliary wheel 5 which moves freely and the footrest 6 which the patient supports with the foot are installed, respectively, and at the rear, the handle 7 which the assistant can hold is extended by bending. have. Between the handles is provided a seat back (8) that can support the back of the patient.

In addition, the upper end of the side member, the armrest 9 of a predetermined height for supporting the arm of the patient is formed integrally with the side member or welded.

When a patient rides or falls in a wheelchair having such a structure, for example, when moving from a bed or a car to a wheelchair, or moving from a wheelchair to a bed or a car, the armrest having a predetermined height is integrally formed on the side member. As a result, the patient had to move through the front instead of through the side of the wheelchair.

That is, since the height of the wheelchair seat is almost the same as the height of the bed or the car seat, it is not possible to move sideways because of the armrest, although it is convenient to move the wheelchair as close to the bed or car as possible and move the body slightly laterally. There was an inconvenience of having to move through the long moving distance. In particular, when a disabled person with an inconvenient lower body gets into or leaves a car through the front of a wheelchair, this is hard and painful.

Republic of Korea Utility Model Application No. 99-13488 discloses a wheelchair that allows the patient to move to the side of the wheelchair by detachable configuration of the seat guard or armrest of the wheelchair. However, the wheelchair having the configuration according to the utility model provides a space for the patient to move to the side after removing the seat guard if necessary, for example, if the patient wants to move from the wheelchair to the car, the wheelchair After the separate plate between the car and there is a disadvantage to move using it. Of course, a separate seat guard may be moved between the wheelchair and the car, but since there is no means of securing the seat guard securely to the wheelchair, the seat guard slips from the wheelchair or the car, which puts the patient in a very dangerous situation. There is this.

The present invention is devised to solve such a problem, the object of the present invention is to provide a wheelchair that is armrest is separated and coupled so that the patient can move forward as well as side.

Another object of the present invention is to provide a wheelchair in which one end of the armrest can pivot about the wheelchair frame and can be temporarily fixed securely to the frame.

In order to achieve the above object, the present invention is a wheelchair provided with each armrest on the upper side member of the frame, the side member includes a cylindrical first and second connecting pipe, at least one of the armrest A first and a second vertical pipe which are separated and coupled to the first and second connecting pipes of the side member, respectively, so that the first vertical pipe of the armrest can rotate with respect to the first connecting pipe of the side member. It provides a wheelchair characterized by having a rotation means.
