Abstract
A skate for a stairlift chair assembly (10) comprises two spaced-apart pairs of rollers, the two rollers (e.g., 27, 28) of each pair being arranged to run respectively above and below a circular section support rail (12) of the stairlift. The two rollers of each pair are rotatable about respective axes (C, D) transverse of the skate, and each roller is able to turn about a further axis (E) which intersects and is orthogonal to the rotary axes (C, D) of the pair of rollers. Each roller is constrained so that its rotary axis (C or D) remains substantially in a plane to which said further axis (E) is perpendicular.
