A method is provided for ensuring the integrity of a stairlift installation constructed from re-used components. Data representative of the form of a stairlift rail is stored in a control facility included in the stairlift carriage and then compared with data sensed in real time. A stairlift carriage may be disabled in the event sensed data varies from stored data.

Stairlifts

The disclosure defined by this invention relates to an electronic control facility for a stairlift. The control facility includes an installation mode in which a number of steps to be undertaken at the time of installation of the stairlift are defined. The control facility also includes a user mode in which the operation of the stairlift is controlled by a user. According to the invention, the control facility is configured so that the user mode cannot be entered until all steps in the installation mode have been completed.

Or relating to stairlifts

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.
