Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wheelchair, and relates to equipment for assisting a wheelchair user in propelling the wheelchair. In order to reach the grip ring provided on the wheel, there is the inconvenience of having to go over the tire of the wheel. When the sky is in the south, the arms and clothes of wheelchair users who try to cross over the tires to reach the port end up getting dirty due to the mud emitted from the rotation of the wheels.

Moreover, if the grip wheels are not conveniently located, it will not be possible to hold the wheelchair, and the grip wheels cannot be seen as an efficient way to propel the wheelchair.

An object of the present invention is to overcome the above-mentioned disadvantages of the strings, that is, to improve them to an optical degree.

Disclosed herein is a wheelchair propulsion aid &flll which is a multi-wheeled wheelchair propulsion assist device operated by a jk prop user. The auxiliary device includes a hand grip capable of being gripped with a hand so that the wheelchair user can hold it, and the grip μ is attached to the wheelchair so as to be movably engaged around the axle of the wheel. However, since the auxiliary device # includes a single wheel engagement device f1 which is fixed to the grip and can be selectively actuated from the end by the wheelchair user, the wheelchair The wheels are held and moved by the wheelchair user by pushing them.

Preferred embodiments of the invention will now be described by way of example with reference to the accompanying drawings.
