DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art As a wheel washer for a wheelchair, a first horizontal rotating shaft, a second horizontal rotating shaft provided in parallel with the first horizontal rotating shaft in the same horizontal plane, and a first horizontal rotating shaft. A rotating roll provided around the outer periphery of the rotating shaft; a fountain roll provided substantially opposite to the rotating roll around the outer periphery of the second horizontal rotating shaft; and a front and rear portion with the rotating roll and the fountain roll interposed therebetween. The first and second horizontal rotations are provided between first and second wheel support plates provided facing upper surfaces of the rotating roll and the fountain roll, respectively, and the first and second horizontal rotating shafts. A third horizontal rotating shaft supported so as to be vertically movable and rotatable with the upper part slightly below the shaft,
A brush roll provided between the rotary roll and the fountain roll around the horizontal rotary shaft, wherein the first and second horizontal rotary shafts are supported so as to be close to and separated from each other; Japanese Patent Application Laid-Open No. Hei 7-59815 proposes a wheelchair cleaner in which the second wheel support plate is supported so as to be able to approach and separate from the first and second horizontal rotation shafts.

[0003] According to this, a rotating roll and a fountain roll, which are arranged substantially opposite to each other, and first and second wheel support plates provided on the front and rear sides facing the upper surface thereof are supported so as to be able to approach and separate. The distance between the rotating roll and the fountain roll and the distance between the first wheel supporting plate and the second wheel supporting plate can be changed according to the diameter of the wheel to be cleaned. It can be supported in a position, even if it is a small diameter auxiliary wheel, it does not fall from the gap, and when cleaning the large diameter rear wheel, it is used by widening the gap after the auxiliary wheel passes Wheel can be placed on a rotating roll and a fountain roll while the person is traveling in the wheelchair and cleaning the device.
It is possible to clean the wheel of a wheelchair alone without the assistance of a helper.

However, in this apparatus, since a cleaning wheel is supported between a rotating roll and a fountain roll, cleaning of a large-diameter rear wheel and cleaning of a small-diameter auxiliary wheel must be performed separately. It is necessary to move the brush roll up and down to a position where it contacts the wheel according to the diameter of the wheel. In addition, since this wheel supports the wheel in the air and sprays water from a substantially lower fountain roll, dirt is less likely to be removed as compared with a case where the wheel is immersed in water, and a longer cleaning time is required. .

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to wash a rear wheel and an auxiliary wheel of a wheelchair at the same time, and at the time of washing, to wash the wheel with a part of the wheel immersed in water. It is an object of the present invention to provide a wheelchair cleaning apparatus which can drop a wheel more cleanly than an apparatus dropped in the air and can wash a wheel in a relatively short time.

[0006]

According to the present invention, there is provided a wheelchair cleaning apparatus, comprising:
An endless body vertically moving device that vertically moves the left and right endless bodies with respect to the water tank simultaneously, and simultaneously rotates the endless bodies on the left and right in the water tank. An endless body rotating device is provided, and swinging arms provided with a fountain nozzle and a cleaning brush are provided rotatably on both sides of the left and right endless bodies, and the swinging arms are simultaneously swung. A nozzle for moving the fountain nozzle and the cleaning brush toward and out of the left and right endless bodies;
A brush access device is provided.

[0007] The left and right endless bodies allow the left and right auxiliary wheels and rear wheels of the wheelchair to be simultaneously mounted thereon.

The wheelchair cleaning device operates as follows. The endless body lifting / lowering device is operated to simultaneously lower the left and right endless bodies on which the wheelchairs are placed with respect to the water storage tank. The endless body lifting device stops operating when the left and right auxiliary wheels and rear wheels of the wheelchair are partially immersed in water.

When the nozzle / brush access device is operated, each swing arm provided with a fountain nozzle and a cleaning brush respectively arranged on both sides of the left and right endless bodies is simultaneously swung,
The fountain nozzle and the cleaning brush are moved toward the left and right endless bodies, and the fountain nozzle is moved to a position facing the left and right auxiliary wheels and the rear wheel. The cleaning brush is in contact with the left and right auxiliary wheels and the rear wheel of the wheelchair.

When the endless body rotating device is operated and the left and right endless bodies are simultaneously rotated, the left and right auxiliary wheels and the rear wheel of the wheelchair are rotated, and almost simultaneously, the valves provided in the water supply pipe are opened. Water is sprayed from the fountain nozzle toward the left and right auxiliary wheels and the rear wheel, and dirt is washed by the cleaning brush abutting on the left and right auxiliary wheels and the rear wheel of the rotating wheelchair.

The left and right auxiliary wheels and rear wheels are soaked in water to make it easy to remove dirt from the wheels as each wheel is rotated. Rubbed by the cleaning brush abutted on the wheel. As a result, dirt on each wheel is simultaneously removed and washed away. In addition, it is possible to clean the wheels more cleanly than in the air, and the wheels can be cleaned in a relatively short time.

When the endless body rotating device rotates the endless body and opens the valve for a predetermined time, the operation of the endless body rotating device is simultaneously stopped and the valve is closed.

Next, the nozzle / brush access device is operated to swing each swing arm at the same time, and the fountain nozzle and the washing brush are retracted from the left and right auxiliary wheels and the rear wheels mounted on the left and right endless bodies. Move to position.

When the operation of the nozzle / brush access device is stopped, the endless body lifting / lowering device is operated, and the left and right endless bodies on which the wheelchairs are mounted are simultaneously raised with respect to the water storage tank. The endless body lifting / lowering device stops operating when it rises to the initial position where the left and right auxiliary wheels and rear wheels of the wheelchair are placed.
