Abstract
A sliding guide that follows the rail in an elevator consists of a guide shoe made of low friction, durable material which is mounted in a shoe retainer. The shoe retainer, in turn, is mounted in an elastomeric pad which is mounted in a bracket that is connectable to the elevator car. The rigidity of the elastomeric pad is adjustable in discrete steps by adding rigid material to the pad. The retainer is adapted to connect with more than one pad. The retainer may, therefore, be attached to two pads, and the rigidity of both of these pads is adjustable.
