#CMT# #/CMT# The barrier has a transmitter (22) and/or a receiver (23) which are movably fastened in an area of a closing edge, and a holder (104) including a four-link edge. The four-link edge is placed in a closing unit that forms the closing edge, where the closing unit is a closing section with a hollow space. The four-link chain has two links connected with the closing edge and a third link that flexibly couples the links with each other. #CMT# : #/CMT# Independent claims are also included for the following: (1) a closing unit for a gate with a light barrier (2) a gate e.g. high-speed run gate, with a gate leaf. #CMT#USE : #/CMT# Used for a gate e.g. high-speed run gate (claimed). #CMT#ADVANTAGE : #/CMT# The utilization of the four-link edge provides smooth-running construction, with which the light barrier is brought from an operating position into a resting position in a simple and reliable manner. The holder is produced in a simple and very cost-effective manner and makes possible an exact guidance. The holder can be designed very flat due to the four-link chain, so that the holder finds place in a very flat profile e.g. roll gate profile. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a 1 : Gate 10 : Gate leaf 12 : Closing edge 20 : Light barrier 22 : Transmitter 23 : Receiver 104 : Holder. |
