CA 2407138

A vehicle with a caster (12) has a disconnectable steering system so the vehicle can be quickly and easily converted back and forth between rider- steerable and externally steerable configurations. The vehicle includes a frame (body) (20), the caster, and a steering mechanism (22, 24, 34) mounted on the frame. A disconnecting device (32) is mounted between the steering mechanism and the caster. When the disconnecting device connects the steering mechanism to the caster, the vehicle can be steered by the occupant since the steering mechanism and caster rotate as one unit. When the disconnecting device disconnects the steering mechanism from the caster, the caster is allowed to swivel freely (360~) about its vertical axis so that the vehicle can be pushed or pulled in any direction by an external operator. The vehicle may be a stroller, a toy vehicle, a scooter, a wheelchair, a cart, a dolly, etc., and it can have more than one caster.

Cette invention concerne un véhicule avec une roulette (12) comportant un système de direction débrayage permettant de changer rapidement de mode de direction : par l'occupant ou par une personne extérieure au véhicule. Le véhicule comprend un châssis (caisse) (20), la roulette et un mécanisme de direction (22, 24, 34) monté sur le châssis. Un dispositif de débrayage (32) est implanté entre le mécanisme de direction et la roulette. Lorsque ce dispositif rend le mécanisme de direction solidaire de la poulie, le véhicule peut être conduit par son occupant du fait que le mécanisme de direction et la roulette tournent d'un bloc. Par contre, lorsque le dispositif de débrayage désolidarise le mécanisme de direction de la roulette, cette dernière peut pivoter librement (360·) sur son axe vertical de telle sorte que le véhicule peut être poussé ou tiré dans n'importe quelle direction par une personne extérieure. Le véhicule peut être une poussette, un véhicule jouet, un scooter, une chaise roulante, un chariot, une servante, etc. et peut comporter plusieurs roulettes.
