Abstract
A drive mechanism for wheelchairs comprises a drive member and a driven wheel hub member journalled on the drive member for rotation about an axis. The drive and driven members each have axial grooves, the grooves in the drive member and the driven member being adapted to be aligned thereby to define axial keyways. A clutch member is rotatably mounted on the drive member and provides axially extending keys. The clutch is movable between an engaged position in which the keys are inserted into the keyways and a disengaged position in which the keys are removed from the keyways.
