CA 2406916

An apparatus (10) that is convertible between walker and a wheelchair that has one pair of wheels (39) that are continually engaged with the ground and a second pair of wheels (209, 219) that are movable from a first position (see figure 2) out of engagement or disengaged with the ground, in which the apparatus (10) is used as a walker, to a second position (see figure 1) into engagement with the ground, in which the apparatus (10) is used as a wheelchair. The movable wheels (209, 219) are controllable by the operator through the use of handle members (200, 210) connected the movable wheels (209, 219). The handle members (200, 210) rotate the wheels (209, 219) into and out of engagement with the ground along a path that is at an angle from the vertical, thereby assuring disengagement of the wheels from the ground.

L'invention concerne un appareil (10) pouvant être utilisé en tant qu'ambulateur ou fauteuil roulant, comprenant deux premières roues (39) qui sont en contact continu avec le sol et deux secondes roues (209, 219) qui peuvent passer d'une première position (voir Figure 2), dans laquelle elles ne sont plus en contact avec le sol et dans laquelle l'appareil (10) est utilisé comme ambulateur, à une seconde position (voir Figure 1), dans laquelle elles sont en contact avec le sol et dans laquelle l'appareil (10) est utilisé comme fauteuil roulant. Les roues mobiles (209, 219) peuvent être commandées par l'utilisateur par l'intermédiaire d'éléments de poignées (200, 210) reliés aux roues mobiles (209, 219). Les éléments de poignées (200, 210) font tourner les roues (209, 219) de manière qu'elles soient ou ne soient pas en contact avec le sol, le long d'une trajectoire inclinée par rapport à la verticale, garantissant ainsi que les roues ne sont plus en contact avec le sol.
