Japanese Patent No. 4213047

  The main problem to be solved by the present invention is that this type of wheelchair wheel cleaning device has a simpler structure and more reliably cleans both while properly supporting the front and rear wheels of the wheelchair. It is in that it can be made.

In order to achieve the above object, in the present invention, a wheel body cleaning device for a wheelchair, a bucket body having a bottom portion and a side portion, having an open top surface and capable of storing a cleaning liquid therein,
A motor roller that is rotatably mounted between the opposite sides of the bucket body;
It is rotatably mounted between the opposite side portions of the bucket body so as to be parallel to the motor roller with a space between the motor roller and opposite to the motor roller by driving the motor roller by the interlocking means. A brushing roller provided on the outer periphery of the roller shaft with a cleaning brush that is rotationally driven by
A first support roller that is parallel to the motor roller and is rotatably mounted between opposing side portions of the bucket body so as to sandwich the brushing roller between the motor roller;
A second support roller that is parallel to the motor roller and that is rotatably supported between opposing sides of the bucket body so that the first support roller is sandwiched between the brushing roller and the brush roller. ,
The upper ends of the motor roller and the first support roller are located above the upper end of the roller shaft of the brushing roller, and the upper end of the second support roller is located above the upper end of the first support roller. ,
The rear wheel of the wheelchair is supported by the motor roller and the second support roller, and the front wheel of the wheelchair is supported by the motor roller and the first support roller.

  The front wheel of the wheelchair received in the cleaning device is supported while being rotated by the rotation of the motor roller between the motor roller and the first support roller. At the same time, a brush of a brushing roller that rotates in the opposite direction to the motor roller is pressed between the motor roller and the first support roller on the lower end side of the front wheel. The rear wheel of the wheelchair received in the cleaning device is supported while being rotated by the rotation of the motor roller between the motor roller and the second support roller. At the same time, a brush of a brushing roller that rotates in a direction opposite to the motor roller is pressed between the motor roller and the second support roller on the lower end side of the rear wheel. Since the cleaning liquid is stored in the bucket body, the brushing roller is pressed against the front wheel or the rear wheel with the liquid contained in the brush, and mud or the like adhering to the brush is contained in the liquid. When the lower end side of the brushing roller passes, the liquid is washed away. Thereby, mud etc. adhering to the front wheel or the rear wheel can be effectively removed over the entire circumference of the front wheel.

If the cleaning device further includes additional interlocking means for rotating the first support roller in the same direction as the motor roller by driving the motor roller, the front wheel of the wheelchair having a small diameter is cleaned after completion of the cleaning. It becomes easy to get over the first support roller from the side opposite to the side where the motor roller is arranged to get out of the cleaning device. Further, the upper ends of the first support roller and the second support roller may be positioned below the upper end of the motor roller. Even in this case, after the front wheel of the wheelchair has been cleaned, it is easy to get over the first support roller from the side opposite to the side where the motor roller is arranged to get out of the cleaning device.

  Moreover, this washing | cleaning apparatus shall be further equipped with the base member which combines with the said bucket body and forms the slope for getting out the front wheel and rear wheel of a wheelchair from this bucket body on the back side of this bucket body. And a base member for forming the slope on the rear side of the bucket body, and a wheelchair when the rear wheel of the wheelchair is on the bucket body between the slope part and the bucket body and the slope part forming the slope. An intermediate support portion that supports the front wheel may be provided so that the lower end of the front wheel is positioned at a level that is the same as or slightly above the lower end of the rear wheel.

  In this case, when the rear wheel of the wheelchair is on the bucket body, the lower end of the front wheel of the wheelchair can be prevented from being positioned below the lower end of the rear wheel. The situation where the wheelchair is moved to the side opposite to the roller arrangement side and the rear wheel is not positioned on the bucket body can be suppressed by supporting the front wheel on the intermediate support portion as described above.

  The wheelchair wheel cleaning apparatus according to the present invention has a simple structure and can be miniaturized. Therefore, while being easy to transport, install and remove, the brush contains cleaning liquid stored in the bucket body. With the brushing roller pressed against the wheel in a state where the wheel is pressed, the wheel of the wheelchair is supported by the motor roller and the first support roller or the second support roller, and this is rotated by the motor roller to ensure that the entire wheel is cleaned. Can be made.
