Abstract
A wheelchair comprises front legs, rear legs and a rearwardly directed support. Large non-swiveling front wheels are located ahead of small swivel wheels which are affixed to the rear frame. The seat and backrest portions are pivotally attached to the front legs. The front legs are hollow tubes with rods passing through to engage rotatable rollers at the floor engaging ends of the legs. The rollers can be locked against rotation to brake the chair or be freely rotatable when the rods are elevated and the chair is to be moved. The structure provides a refined and aesthetically pleasing wheelchair suitable for long term, geriatric use. A foot support is foldable between an extended position ahead of the seat and a position below the seat, the foot support blending neatly with the seat portion of the chair.
