摘要：
A wheelchair which employs heuristic height adjustable track mechanism for all terrain uses including stair climbing comprising four inverted triangular shaped tracks, mounted on two T-shaped track frames to form front and back track sets sprockets and rollers on which the inverted triangular shaped tracks are placed before mounting on the T-shaped track frames mounting points for rollers on the track frame a motor whose shaft is coupled to a sprocket on the front track frame two parallel connecting rods to keep the T-shaped track frames parallel to each other a seat assembly comprising of a seat frame on which a seat is mounted, arm rest, foot rest, joystick for changing the direction of movement of the wheelchair and actuator switch for adjusting the angle of the chair according to the height of the obstable/step to be climbed an actuator attached between the seat frame and one of the track frames whose length/size is adjusted according to the height of the obstacle or step a chain sprocket mechanism consisting of two chain sprockets on either side of a motorized sprocket of the front track frame which connects it with a non-motorized sprocket of the back track frame by means of a chain a track frame separator for separating the T-shaped frames of the track sets a controller attached to the framework to which the motor and joystick wiring are connected batteries and side plates to prevent the inverted triangular shaped tracks from slipping off the sprockets.
