#CMT# #/CMT# The door has a light barrier (30) arranged in a predetermined distance (B) from a closing edge (12) in an area (C) between another light barrier (20) and the closing edge, where the distance (B) is lesser than 50 millimeter (mm). A distance (A) between the light barrier (20) and the closing edge and/or the distance (B) between the light barrier (30) and the closing edge are changeable. The two light barriers are movable relative to a door leaf (10) by a drive. #CMT#USE : #/CMT# Door e.g. high speed door. #CMT#ADVANTAGE : #/CMT# The light barrier is arranged in the predetermined distance from the closing edge in the area between another light barrier and the closing edge, thus monitoring the area between the latter light barrier and the closing edge. The light barrier hence serves an anti-trap protection to prevent jamming of objects or body parts during the closing process of the door and to provide high safety during door usage, in accordance with safety regulations, standards and measures. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a door. A, B : Distances C : Area 10 : Door leaf 12 : Closing edge 20, 30 : Light barriers. |
