Description of a mechanized chair that uses a tank track system in order to easily allow a person to go up and down stairs in a wheelchair. The system consists of a four bar mechanism that keeps the seat of the chair parallel to the ground, preventing the user from falling backward or tipping over. The system is controlled using manual switches to move the four bar system. The drive system consists of three worm gear electrical motors. The system is operated by two manual toggle switches, one that operates the two drive motors and one for the Grashof double-crank four bar mechanism, which controls the chair’s position. A picture of the chair included shows the prototype, which is a scale model of the actual system. The All Terrain Track Chair was designed by students at the Mechanical and Aerospace Engineering Department at the State University of New York at Buffalo.
