The invention provides for a method of operating a stairlift, the stairlift having non-contact sensors to monitor the path along which the stairlift carriage is traveling, and to determine the presence of an obstruction on that path. Features of the stairlift in a 'safe' or 'un-obstructed' mode, including the path, may be stored as a &#x2018;map&#x2019; in memory and sensor readings compared with the map as the carriage moves along the path. The invention allows the use of momentary commands to initiate and maintain movement of the stairlift.

Stairlift obstruction monitoring

The present invention provides a stairlift rail of non-circular cross-section. The wall surfaces of the rail define a single internal cavity and the outer surface of the rail is free of additional members added to the rail in order to prevent rotation of a stairlift carriage about the rail axis.
