The invention provides a method of controlling a stairlift, and a suitable stairlift, along a track that may be curved (Fig 8) or may have two or more sections with differing angles or directions of slope (Fig 7). The stairlift 10 comprises a rail 12, a carriage 11 and safety edges 16 and 17 for detecting obstructions. There may also be a safety edge 18 under the footrest 15. The safety edges are under the control of a control system 22 and are selectively activated independent of the requested or actual direction of travel. When an obstruction is contacted by the safety edges, the control system only permits movement away from any obstruction and has means for controlling the speed of such movement. The stairlift may have position and direction sensing facilities and a memory recording the direction of slope at each point on the rail. |
