Embodiment Construction

[0038] figure 1 Selected portions of elevator system 20 are shown schematically. Only selected portions are shown. Those skilled in the art will appreciate that many other components are included in the elevator system (eg, guide rails, buffers, governors, machines, brakes, drives, controllers, traction members, etc.). For the sake of brevity, and because such components are already recognized by those skilled in the art, such components are omitted from the illustrations and discussion.

[0039] Elevator car 22 is movable within hoistway 24 . Surface 26 near the bottom of hoistway 24 may be the floor of the well or the bottom hoistway surface in examples where the bottom of hoistway 24 does not include a well.

[0040] A toe guard assembly 30 is provided on the elevator car 22 to cover the bottom of the elevator car 22 and the adjacent landing if for any reason a hoistway door (not shown) should be opened before the car is properly aligned with the landing. space between....

Abstract

An exemplary elevator toe guard assembly includes a first panel. The second panel is slidable relative to the first panel in a first direction between an extended position and a retracted position. In response to the second panel moving toward the retracted position, the first panel moves in a second, different direction from the extended position toward the folded position.

Description

technical field [0001] The present invention relates to toe guard assemblies for elevator systems. Background technique [0002] Elevator cars typically include toeguards located below the elevator car. Toe guards are usually rigid and approximately one meter in length. Some toe guards are up to two meters long. Consequently, a significant amount of clearance is required below the elevator car to avoid the toe guards hitting the bottom of the shaft when the elevator car is on the lowest landing. [0003] Elevator systems have included a well at the bottom of the hoistway, in part to provide sufficient clearance between the bottom of the elevator car and the bottom of the hoistway. Typical well pit configuration provides enough clearance for typical toe guards. Recently, however, elevator shaft pits have been eliminated or reduced in size. Conventional toe guards do not allow the elevator car in such systems to travel as low as possible. [0004] One proposal to solve t...
