Abstract
A wheelchair camber tube assembly for supporting rear drive wheels comprises a tube, an inner camber sleeve, an axle sleeve and a locking mechanism. The inner camber sleeve is slidably engageable within the tube. The inner camber sleeve has a central axis and a cylindrical bore. The said cylindrical bore has a central axis disposed at an angle relative to the central axis of the inner camber sleeve. The axle sleeve is rotatably engageable within the cylindrical bore in the inner camber sleeve. The axle sleeve has a central axis and an axle bore therein. The axle bore has a central axis disposed at an angle relative to the axle sleeve central axis. The locking mechanism is operatively engageable with the axle sleeve.
