Abstract

PROBLEM TO BE SOLVED: To enable self-driving by a wheelchair, such as running on a bad road, a barrier, a gravel road, a ditch, a sandy beach, on snow, a lawn by a wheelchair. We shall reduce the burden and improve the daily life of the disabled.
SOLUTION: The present invention provides a gravel road, a groove, a sandy beach, a snowy road, by rotating a geared driving wheel 5 from a rim with a hand grip 2 through a synchronizing device 4 and interlocking with a caterpillar type tire 7. Riding with a wheelchair, such as running on the lawn, enables self-driving by a wheelchair, prevents garbage dirt and eliminates hand hygiene by using a hand grip (2) and hand grip (3), and reduces the burden on the waist by using a spring (8) Can contribute to the improvement of the rich daily life of the disabled.

Description

  The present invention uses six wheelchair wheels to contribute to improving the daily life of disabled people, such as enabling the wheelchair to travel on rough roads, and contributing to improving the daily life of disabled people, such as preventing clothes from being stained, eliminating hand hygiene, and reducing the burden on caregivers. The present invention relates to a wheelchair in which a tire portion is formed in a caterpillar shape, a hand rim conventionally attached to a wheel is made independent, and is manually driven by a rim with a hand grip.

    Most of the conventional wheelchairs run by manually turning a wheel-integrated hand rim. Therefore, there is a case where clothes are soiled by the wheels and hand hygiene is inevitable. In particular, there is a wide variety of wheelchairs, and it is extremely difficult to drive a wheelchair on bad roads or barriers such as gravel roads, ditches, sandy beaches, snow and lawns. Wheelchair users became independent on their own activities, such as visiting shrines and temples, gravel roads, and lawn driving, such as sandy beaches and sandways in the sea, snowy roads in snowy countries, and snowy seasons. It is extremely difficult to improve the quality of life in social activities and daily life.

  Enables self-propelled driving on wheelchairs, such as traveling on rough roads, ditches, sandy beaches, snowy fields, and lawns, which are relatively rough roads in everyday life, preventing clothes from becoming dirty, eliminating hand hygiene, and reducing the burden on caregivers. The present invention is aimed at solving the above-mentioned drawbacks with the present invention, which leads to the enrichment of daily life for persons with disabilities.

  In the present invention, caterpillar-type tires are attached to the front and rear small driving wheels with the wheel of the wheelchair as the fulcrum of a non-conventional geared driving wheel, the hand rim is made independent of the wheel, and the force from the rim with hand grip is transmitted. By rotating the caterpillar-type tires in conjunction with the geared drive wheels, dirt such as jumping onto clothes is prevented, eliminating hand hygiene, reducing the burden on caregivers, and gravel roads and grooves that are rough roads and barriers -Solves problems by enabling self-driving with a wheelchair, such as running on sandy beaches, on snow, or on grass.

  As described above, the rough road traveling self-propelled manual type normal wheelchair of the present invention is equipped with caterpillar type tires on the tire parts of the non-conventional geared drive wheels and the front and rear small drive wheels, and the synchronization equipment and gears are attached. By transmitting power from the rim with handgrip to the drive wheel with gears as a fulcrum, it is possible to drive on a wheelchair, such as traveling on rough roads, grooves, sandy beaches, snow and grass, which are rough roads in everyday life In addition, it helps prevent stains on clothes, eliminates hand hygiene, and reduces the burden on caregivers.

Best mode for carrying out the invention

  Turn the handgrip of the rim with handgrip by hand to rotate the wheelchair, transmit power to geared drive wheels via synchro equipment, and rotate the caterpillar type tire to drive on the above-mentioned rough roads and barriers Let The hand-held rim is equipped with a base handgrip so that force can be smoothly transmitted to prevent contamination of clothes and eliminate hand hygiene. Further, by attaching a spring to each drive wheel portion, the burden on the waist can be reduced and the impact can be prevented.

  Hereinafter, an embodiment will be described with reference to the accompanying drawings. Reference numeral 1 denotes a wheelchair main body, reference numeral 2 denotes a rim with a hand grip for running the wheelchair 1, and reference numeral 3 denotes a hand grip serving as a base shaft for rotating the rim with the hand grip. Reference numeral 4 denotes a synchronizing device for transmitting a force from the rim with the hand grip 2 to the driving wheel with gear 5, reference numeral 5 denotes a driving wheel with gear, reference numeral 6 denotes a small driving wheel interlocked with the driving wheel with gear, and reference numeral 7 Is a caterpillar type tire. As a result, it is possible to prevent the clothes from being stained, eliminate the unsanitaryness of the hands, and run a wheelchair that can overcome the above-mentioned rough roads and barriers.

  Reference numeral 8 denotes a spring portion for enhancing the cushioning property of the wheelchair 1, which can significantly reduce the burden on the waist during running.

  Since one embodiment of the present invention is constructed as described above, the power is transmitted from the rim with the handgrip by rotating the handgrip by rotating the handgrip, and the gear with the gear is transmitted through the synchro equipment. It is of course possible to make one wheelchair run comfortably by interlocking with the drive wheels, but even when the assistant pushes one wheelchair to assist, the burden on the assistant on the above-mentioned rough road / barrier is reduced. It can greatly contribute to the daily life, and can improve the rich daily life.
