Mc HandPedal®


This Invention is a hand propulsion device to be fitted to the axle of the majority of wheelchairs on the market around the world today

Many wheelchairs today are self propelled by the means of a hand rail surrounding the outer rim of the wheelchair wheel.

This can be hard work on hills or long journeys. Alternatively, this can also be difficult on a person's arms, shoulders and elbow joints. Many of the wheelchair propulsion devices on the market today are of the push and pull configuration, which all extend past the wheel and tire rims of the wheelchairs where your arms are pushed to full extension and pulled back towards your stomach and chest.

This invention is for an alternative manual means of wheelchair propulsion which is attached to the rear large wheels axle of wheelchairs and driven by means of pressure onto a handle in circular motions within the outer rims of the wheelchair wheels. This device, the wheel winder is extendable to the outer wheel rim as well as retractable to be close to the wheels axle, also with gearing so a number of methods of pressure for propulsion can be used.

This also would be used by means to slow a person down using the HandPedal attached to a wheelchair. A pawl switch is attached for forward rotation, rear rotation, locked position & neutral.

The wheelchair hand wheel winder which is fitted to the axle of both large rear wheels of wheelchairs, Is either fitted into place at manufacture at the axle, as a socket where the wheel winder can be fitted and detached quickly by ball joint quick release mechanism, or as an attachment to the axle and surrounding area making the socket sturdy fit to the outer axle, this will show no movement whatsoever so as not to buckle or damage the spokes or relevant wheel design that is in place.

Then the wheel winder simply slots into the socket of the wheelchairs wheel, locking into position and released if needed to.
