Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a retractable elevator foot guard. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] In the elevator industry, to ensure passenger safety, industry regulations mandate that elevator cars must be equipped with foot guards. Currently, elevator car door foot guards are typically fixed to the bottom of the car and are always stationary. When an elevator stops mid-journey due to leveling issues, the car may become stuck near the upper part of a floor. When the elevator doors open, conventional foot guards sometimes fail to effectively block the exposed doorway below the elevator. The resulting backflow can easily pull rescue personnel or those being rescued near the entrance into the shaft pit, causing injury or death. Furthermore, relying solely on fixed, variable-length foot guards would require digging deeper into the shaft pit, resulting in significant waste.

[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model.
