SAFETY DEVICE FOR PREVENTING HAND FROM BEING JAMMED IN ELEVATOR DOOR

摘要

The present invention provides a safety device for preventing a hand from being jammed in an elevator door including a conductive member attached to the surface of the door and the door frame whereby if the conductive member is contacted by the hand, it senses the current of the human body so as to control the elevator door, preventing the hand from being jammed in the door, and directly illuminates the surface of the door so as to enable the person to clearly see the hand contacting the door and to be warned.

主权项

1. A safety device for preventing a hand from being jammed in an elevator door, the safety device comprising:
a door LED board (110) that is provided on a surface of an elevator door (10) opened or closed by the driving of a door driving motor (40), which is positioned between a car frame (20) and an entrance frame (30) provided at an elevator car (1) and an elevator entrance (2) and is controlled by control means (50), and that is provided on a surface of a door LED board (110) configured such that a plurality of door LEDs (112) which is turned on or off by the control means (50) is provided on a surface of a door printed circuit board (PCB) (114); a door conductive member (120) that is provided on a surface of the door LED board (110) so as to turn on the door LEDs (112) by the control means (50) when a current of a human body is detected, and that is made of a transparent or translucent material; a frame LED board (130) that is configured such that a plurality of frame LEDs (132) is provided a frame printed circuit board (PCB) (134) on surfaces of corners of the car frame (20) and the entrance frame (30); and a frame conductive member (140) that is provided on a surface of the frame LED board (130) to detect the current of the human body.
