Anti-crash security stop for gates - has stop plate in driving connection with drive cams and return springs

摘要

The stop plate (6) is connected to a drive shaft (8). The plate is also connected with the gate shaft (2) via the stop wheel (3). The plate engages in rotary direction on the stop wheel, by one or more drive cams (9,10) and via return springs (11). The cams engage into grooves (12) of the stop wheel, which also contain the return springs. The recesses (7) in the stop plate, and the collection chambers (14) in the housing section (5a), are quadrant-shaped. ADVANTAGE - Device functions, even when the drive effect from the drive does not any longer act on the gate shaft.
