Description

Technical Field

[0001] The present application relates to the field of elevators, and in particular to a device for keeping an elevator door open. Background Art

[0002] Elevator door protection is generally divided into infrared (light curtain), safety touch panel, touch panel + light curtain / photo eye, etc. It is a protective measure to prevent passengers from being hit or pinched by the elevator door when entering and exiting the elevator car. At present, in order to prevent the elevator door from pinching passengers during the closing process, a safety touch panel (or photoelectric or light curtain) is generally installed on the elevator door.

[0003] In the prior art, the elevator door will automatically close without human intervention. Blocking the elevator door with obstacles to prevent it from closing will pose a great safety hazard.
