Locking elevator car frame to building during loading/unloading horizontally moveable cab

摘要

To prevent elevator rope stretch effects when a horizontally transferable elevator cab (18) is rolled onto and off of an elevator car frame (10), an elevator car/floor lock (31) includes a bolt (37) which extends across the interface between the car frame and the building and engages a strike (39) . Jack screw (44) and solenoid (60) embodiments are shown. The bolt may extend from the car frame to the building (FIGS. 1- 4) or from the building to the car frame (FIG. 5).
