Abstract
The present invention is an improved anti-tip wheel assembly for a wheelchair. The preferred embodiment of the assembly includes a cam mechanism to allow the initial height of an anti-tip wheel above ground to be adjusted dependent on the obstructions which the wheelchair is expected to encounter. The cam mechanism fixes the position of the anti-tip wheels to prevent the wheels from unintentionally displacing when an anti-tip wheel contacts the ground or an obstruction.
