Abstract
An anti-tip mechanism for use with a wheelchair is provided. The anti-tip mechanism has a support frame being adapted to be coupled to the wheelchair. A first and a second wheel support arm extend outwardly from the support frame and are pivotally coupled thereto. A wheel is rotatably connected to each of the support arms. An adjusting mechanism is coupled between the frame and the support arms. The adjusting mechanism is adapted to change the position of the support arms relative to the frame. In this manner, the adjusting mechanism is adapted to raise and lower the wheels. The anti-tip wheels of the wheelchair are thus adjustable to different fixed positions relative to the support frame by operation of the adjusting mechanism.
