Barrier having a barrier beam which can be angled over its length

摘要

The barrier having a barrier beam (5) which can be angled is equipped, for the transmission of the pivoting movement to the section (5b) which can be angled, with a chain drive which runs along the drivable section (5a) and has an endless chain (10) and chain wheels (11 and 12). The one chain wheel (11) is held, fixed in position and secured against rotation, on the pivot shaft (4) mounted in a housing and connected to a driving device. The other chain wheel (12) is rotatably held on a joint shaft (13) connecting the two sections. The joint shaft (13) is connected to the drivable section (5a) so as to be rotatable and to the section (5b) which can be angled so as to be secure against rotation. <IMAGE>
