Abstract:
1. A kit for the assembly of a stairlift guide rail, said kit comprising a plurality of sections of guide rail, wherein said sections have predetermined standard dimensions, wherein said kit comprises a first set of sections of guide rail having vertical curvature at a variety of different angles which are adapted to negotiate decreasing gradients from the vertical to the horizontal and a second set of sections of guide rail having vertical curvature at a variety of different angles which are adapted to negotiate increasing gradients from the horizontal to the vertical, wherein said first set of vertical sections of guide rail optionally have vertical curvature at a range of angles which range between 8° and 58°, with a tolerance of between 0.5° and 1°, and said second set of vertical sections of guide rail optionally have vertical curvature at a range of angles which range between −8° and −58° , with a tolerance of between −0.5° and −1°.
