DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding wheelchair oxygen cylinder stand which can be easily attached and detached without using screws or tools.

[0002]

2. Description of the Related Art Conventionally, a folding wheelchair oxygen cylinder stand is provided with a frame or a bolt or the like which extends rearward from a frame below a rear portion of a folding wheelchair or a frame which is vertically branched. Was fixed at

[0003]

Conventionally, when a patient in need of oxygen in a hospital or the like moves in a wheelchair, it is often seen that the patient is equipped with a housing for storing an oxygen cylinder. Or it was fixed with bolts and it was very inconvenient to attach and detach. Therefore, the present invention is for a foldable wheelchair that can be easily attached and detached without using screws and bolts and tools, can be attached to either of the left and right handles of a wheelchair, and can be folded while storing an oxygen cylinder. To provide an oxygen cylinder stand.

[0004]

The present invention will now be described. To explain the present invention, a frame extending rearward from a lower frame and a vertically extending branch are provided below the rear portion of a folding wheelchair equipped with main wheels and sub wheels. There is a frame, the rearward extension becomes a travel assist bar, a tubular body is inserted into the travel assist bar, and the tubular body is attached to the wheelchair with an extendable hook so that the tubular body does not fall off. Hook and fix on the main wheel bearing vertical frame, attach a column vertically to the tubular body, attach an annular body into which the oxygen cylinder enters, at an appropriate position where the cylinder can be stored above and below the column, and An oxygen bottle for a foldable wheelchair, characterized in that an elastic hook is attached to a tip, and the hook is hooked on a handle portion of a handle of the foldable wheelchair to store an oxygen cylinder in the annular body. Vertical.

[0005]

The tubular body 7 below the oxygen cylinder stand is inserted into the travel assist bar 24 extending rearward from the frame below the rear part of the folding wheelchair 20, and is telescopically attached to the lower part of the column 6. Hook 11 is hooked on the main wheel bearing vertical frame 23 which branches vertically from the frame below the rear of the wheelchair. Next, the knob 2 of the slide hook main body 5 above the oxygen cylinder stand is pulled up, and the hook 3 of the slide hook main body 5 is hooked on the handle portion handle portion 22 of the wheelchair. Next, the oxygen cylinder 30 is inserted into the annular body 8 attached to the column 6, and is housed in the annular body 9 having the band-shaped body 10 on the bottom.

Embodiment

FIG. 1 is a perspective view of an oxygen cylinder stand according to the present invention. First, the support 6 is vertically attached to the cylindrical body 7 of an appropriate length, and the support 6 is provided with the upper annular body 8 and the lower annular body 9 provided with the band-shaped body 10 at the bottom. At the lower part of the column 6, a telescopic hook 11 for fixing the tubular body 7 is attached to the lower part 12 of the column 6. The mounting part 12 is movable and fixed.

An extendable slide hook 1 is attached to the upper end of the column 6, and a spring 15 is provided inside the slide hook body 5.
The column 6 and the slide hook 1 pull each other by fixing it to the upper 16 portion of the inside and fixing the lower portion to the upper end 17 of the column 6. The spring 15
It is also possible to attach it to the outside of the slide hook body 5.

Next, cuts 14 are made vertically in the lower part of the slide hook body 5 on both sides facing each other, so that the slide hook body 5 does not come off from the support 6, and the support 6 and the slide hook body 5 can slide. The bolt 13 having such a structure is fixed by passing through the vertical notch 14 and penetrating the column 6, and the knob 2,
And hook 3 is attached, and slip stopper rubber 4 is attached to hook 3.
Attach

[0009]

When mounting the oxygen cylinder stand according to the present invention on a folding wheelchair, it can be easily attached and detached because screws and tools are not used, and the attachment can be selected on either the left or right handle. It is very convenient because it can be folded while storing the oxygen cylinder.
