Abstract:
A skate (20) for a stairlift chair assembly, said skate comprising two spaced-apart pairs of rollers, the two rollers of each pair being arranged to run respectively above and below a support rail of the stairlift, said two rollers of each pair being rotatable about respective axes (C,D) transverse to the moving direction of said skate, and each roller of each pair of rollers having its opposite ends engaged with respective, opposed support members in a manner such that said roller is able to turn, relative to its support members, about a further axis (E) which intersects and is orthogonal to the rotary axes (C,D) of said pair of rollers, but is constrained so that its rotary axis (C or D) remains substantially in a plane to which said further axis (E) is perpendicular.
