Abstract
A stair lift includes a track, a carriage, a drive mechanism and a folding mechanism. The track has a main track section and a lower track section. The lower track section is pivotally mounted to the main track section and is moveable between a lowered position and a raised position. The folding mechanism shifts the lower track section to its lowered position whenever the carriage and seat approach the lowermost stairs and lifts the lower track section to its raised position as the carriage and seat move up the stairway. The folding mechanism is actuated and powered by movement of the carriage and does not require its own motor, cylinder, or other actuator.
