Abstract
A guidance mechanism for an elevator car is constructed and arranged to move along a lane defined at least in-part between two opposing first and second lane structures of a stationary structure. The guidance mechanism includes a first support structure supported by the first lane structure. The first support structure includes a first retainer face disposed between the elevator car and the first lane structure that substantially faces the first lane structure, and is spaced from the first lane structure. A first retention device of the mechanism is disposed, at least in part, between the first retainer face and the first lane structure. The first retention device is supported by the elevator car and is constructed and arranged to contact the first retainer face for limiting lateral movement of the elevator car away from the first lane structure and toward the second lane structure.
