Abstract

PROBLEM TO BE SOLVED: To improve practicality by permitting setting optionally the longitudinal position of an armrest material by mounting the armrest material longitudinally movably on a part of the armrest receiving material of a chair and enabling a table, or the like, to be carried on the armrest material when the armrest material is moved forward. SOLUTION: Armrest materials are mounted longitudinally movably on plate- form armrest receiving materials 2 attached integrally to the horizontal portions of pipe frames arranged on both sides of a wheelchair. The shape of the cross section of the armrest material 2 is a grooved rectangle, both ends of which are bent inwardly, mounted by inserting slidably into the armrest receiving materials 1. Usually, the armrest materials 2 are moved forward to use as long armrests and a table or the like can be mounted astride both armrest materials 2 and 2. When a user is getting on or off the wheelchair or approaching a washstand, a desk or the like, the armrest materials 2 are moved rearward to be shorten and, them.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an armrest for a wheelchair.

[0002]

2. Description of the Related Art Conventional wheelchairs for a wheelchair include a fixed type and a detachable type. In addition, the length of the elbow rest is both long and short.

[0003]

It is usually convenient to increase the length of these elbow rests, but it is better to shorten them when going up and down a wheelchair or approaching a washbasin or a desk. Also, you cannot put things on the elbow pad or use it as a substitute for a desk.

According to the present invention, there is provided an armrest for a wheelchair in which an armrest can be moved back and forth, different armrests can be attached to and detached from the armrest, and the surface of the different armrest can be used as a table. It is intended to provide.

[0005]

In order to solve the above-mentioned object, in the elbow rest of the wheelchair according to the present invention, the elbow rest can be attached to the elbow rest receiving part of the chair, and the elbow rest receiving part can be attached to the elbow rest receiving part. With the elbow rest attached, the elbow rest can be moved in the long side direction of the elbow rest. The position of movement of the elbow rest is an arbitrary position before and after the backrest surface of the wheelchair.

[0005] In order to solve the above-mentioned problem, different elbow rests can be attached to and detached from the elbow rest of the wheelchair at an arbitrary position, and the width of the different elbow rests is made larger than the width of the elbow rest. .

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on examples with reference to the drawings. In FIG. 1, the cross section of the elbow pad 2 has a groove-shaped rectangular shape with both ends bent.
In FIG. 2, the elbow receiving member 1 fixed to the pipe frame 4 has a rectangular cross-sectional shape. And FIG.
As shown in FIG. 4, the elbow pad 2 and the elbow pad 1 are rubbed, and the elbow pad 2 is mounted with the elbow pad 1 inserted inside the elbow pad 2, as shown in FIG. The elbow rest 2 can be moved in the long side direction. The elbow rest 2 can be moved at any position before and after the backrest surface 3 as shown in FIGS.

In FIG. 8, a different elbow pad 10 is formed at the elbow pad 2 in a detachable shape. Then, as shown in FIG. 9, a different elbow pad 10 is attached to the elbow pad 2. The width A of the elbow pad 2 is different from the width of the elbow pad 10.
Is smaller than the width B. The width B of this different elbow pad 10 is 2
When the size is 0 cm or more, as shown in the mounting use example of FIGS.

When the height H of the different elbow pads 13 is increased as shown in FIG. 12, the horizontally projecting portions 11 of the different elbow pads 10 do not hit the knees and do not interfere.

[0008] In the different elbow rests 10 shown in FIG. 13, the size of the contact portion of the different elbow rests 10, which is mounted in contact with the part of the elbow rest 2, is adjusted according to the thickness h of the elbow rest 2. I can do it. This different elbow rest 10
Can be attached as long as the elbow pad has a rectangular cross-sectional shape.

[0009]

Since the present invention is configured as described above, it has the following effects.

[0010] Since the position of the rear end of the elbow pad attached to the wheelchair can pass through the backrest surface, the elbow pad can be moved, so that it is usually used as a long elbow pad, and when the wheelchair is raised or lowered, or When approaching a washbasin or a desk, you can move the elbow pad backwards and use it shorter.

If different wide armrests can be attached to and detached from the armrests so that they can be attached to and detached from the armrests when necessary, the surface of the different armrests can be used as a table.

The use of different elbow rests having a large height is convenient because a table-like table can be formed at a position higher than the elbow surface. This device can be installed and used on fixed chairs other than wheelchairs.

Further, when a different elbow pad which can be attached and detached by adjusting according to the thickness of the elbow pad 4 having a rectangular cross section is used, it can be used for chairs other than wheelchairs.
