Assembly for translational movement of wheelchair wheels for persons with motor disabilities

An assembly for fitting to a wheelchair driven manually by circular push rings on the wheels, said assembly comprising:

• at least one device including two parts mobile relative to one another, namely a guide provided with quick fixing means, in particular by clamping, in horizontal position, a wheel slide guided by said guide and having a transverse axle or transverse sleeve for mounting with a rear wheel around the transverse axle or transverse sleeve so that a rotation of said rear wheel on a ground drives the movement of the wheel slide along the guide between an advanced position and a retracted position in which the rear wheel no longer protrudes on the side of the seat of the wheelchair,
• means for manually actuating respectively an advanced and a retracted position, immobilization means of the wheel slide in said advanced, respectively retracted, position, the length of said elongate wheel slide being such that, in the retracted position, said wheel slide can exit the rear end of the guide with an overhang, the wheel slide remaining retained in the guide by its anterior part, said advanced and retracted position immobilization means including manually unlockable clipping means and unclipped position retaining means enabling the user to free their hands to drive said wheel of the wheelchair between said advanced and retracted positions, and automatic unlocking means enabling return of the manual unlockable clipping means into a clipping position upon movement of the wheel slide,
• wherein said manually unlockable clipping means include an elongate lever articulated in pivoting manner on one of the wheel slide or the guide and actuatable by a hand lever, said lever and the one of the wheel slide or the guide that does not carry said lever including respective complementary clipping elements, namely two complimentary clipping elements spaced by a distance equal to the distance between said advanced and retracted positions, and an abutting element, adapted to be clipped together when said wheel slide reaches the advanced, respectively retracted, position, said lever being able to pivot between an unclipped position and a clipped position.
