FIG. 6 is a right side view showing the use state of the wheelchair wheel cleaning device 1 of the present invention. The occupant of the wheelchair 73 travels through the right handrail 59 and the left handrail 60,
In the retreating operation, the wheelchair wheel cleaning device 1 is slowly climbed from the inclined guide plate 56 having an inclination angle of 10 °, and the rear wheels are driven by the rollers 13, 13.
When the switch 27 comes into the working position, the rear wheel of the wheelchair 73 comes in contact with the uphill slope of the upper cover 28, and
Wheelchair 73 stops. Then, while the light emitted from the light emitting diode 51 reaches the light receiving transistor 52, the light is blocked by the rear wheel of the wheelchair 73.

When the wheelchair 73 is completely stopped and the safety is confirmed, and then the main switch 64, which is the main power switch, is pressed, the time required for the rear wheel to make one or more rotations in the direction of arrow C is approximately obtained. The rollers 13, 13 for driving for 30 seconds rotate in the direction of arrow A (clockwise), the rotating brush 22 rotates in the direction of arrow B, and the rear wheel rotates in the direction of arrow C. Since the surfaces rotate in opposite directions, the rotating brush 22 can sufficiently remove dirt in the tread (groove of the tire) of the rear wheel. Then, the scraped-off dirty dust is dropped and stored in the lower dust box 50. In this way,
The wheelchair wheel cleaning device of the present invention operates. After the operation of the wheelchair wheel cleaning device 1 is completed, the occupant may move the left and right handrails 5.
The rear wheel of the wheelchair is moved from between the rollers 13 and 13 along the wheels 9 and 60, and the wheelchair is slowly moved down the downhill of the inclined guide plate 56 to complete the cleaning operation. The present invention mainly relates to cleaning of the rear wheel of the wheelchair 73, and since the front wheel does not have a deep groove like the rear wheel, dirt easily falls off when passing over a mat as in the conventional case. Cleaning shall be omitted. In addition, the present invention can provide a small-sized wheelchair wheel cleaning device 1 that is inexpensive because facilities such as a tank and a pipe for a cleaning liquid are unnecessary.

[0020]

According to the wheelchair wheel cleaning device of the present invention, the occupant of the wheelchair can use the left and right handrails to perform the backward movement with the inclination angle of 10 degrees.
It can be easily, easily and safely used by easily climbing up the slope of the inclined guide plate of ° and stopping at the rear wheel cleaning position. In addition, after confirming the existence of the rear wheel at the stop position with a switch using an optical element, and further confirming that the rear wheel is securely in contact with the rotating brush, the main switch which is a main power switch is pressed down. Then, the cleaning operation is started. Then, the time required for the rear wheel to make one or more rotations is about 30 seconds.
The roller for driving for 2 seconds rotates in the direction of arrow A (clockwise), the rotating brush rotates in the direction of arrow B, and the rear wheel moves in the direction of arrow C.
In the contact direction with the rotating brush, so that dirt in the tread (tire groove) of the rear wheel can be removed well. Then, the scraped-off dirty dust is dropped and stored in the lower dust box 50, and when a certain amount of dirty dust accumulates, the lock member is released, and the power transmission mechanism with the upper cover is rotated upward. The dust box can be easily taken out and cleaned, which is convenient.

Further, according to the present invention, the rear wheel to be cleaned is located between the drive rollers and is in contact with the rotating brush, so that turning on the main power switch is effective only when, for example, a mischievous child is in the wheelchair wheel. Even if you are playing at the cleaning device, it is safe because it does not start unless the three switches work. Furthermore, the present invention can provide a small and inexpensive wheelchair wheel cleaning device because the inclined guide plate is disposed for only one side of getting on and off, and because it has a small installation area, it can be installed in an installation place such as a narrow entrance of a general household. it can. In addition, since no cleaning liquid or the like is used, there is no solution tank or piping equipment, so the structure is simple, the handling is easy, and the wheelchair wheel cleaning device is inexpensive.
