Abstract
Abstract A wheelchair carrier is described which is mounted on the rearwardly extending hitch of a vehicle such as an automobile or the like. A platform is pivotally mounted on a horizontally extending support which is operatively mounted on the vehicle hitch. The platform may be pivotally moved from a horizontal carrying position to an inclined loading and unloading position. When the platform is in its inclined position, one end of the platform may be positioned beneath the handles of the folded wheelchair with the wheelchair then being moved towards the carrier. Pivotal movement of the carrier from its inclined position to its horizontal carrying position causes the wheelchair to be lifted from the ground and positioned on the carrier. The carrier is locked in its horizontal carrying position by means of a spring-loaded lock. The wheelchair is held on the carrier by means of a spring-loaded connector.
