Abstract

1. A catching device for roller gates roller grilles or similar winding devices wherein a) a tripping device (3, 4) is mounted on a hub (12) rotatable with a drive or guide shaft (10) in such a manner that, on exceeding a permissible speed of the drive or guide shaft, it brings about the engagement of a locking device (5, 6) operating between it and a fixed point (2), and b) the locking device (5, 6) is fitted with a deformable energy absorber (7, 8, 9) to damp and transform (destroy) the kinetic energy of the winding drive, characterised by c) a brake disc (7) and d) deformation elements (9) arranged on an annular supporting member (8; 14, 15) on both sides of the brake disc (7), evenly distributed over the circumference of the brake disc (7) and staggered relative to one another, which elements are arranged in axial direction so that the brake disc (7) in every operational situation is peripherally deformed in wavy manner, and the supporting member (8; 14, 15) rotates with the brake disc in the normal movement of the winding drive ; wherein either the brake disc (8) is non-rotatably connected with the drive or guide shaft (10), and the supporting member (8; 14, 15) is able to be fixed by the locking device (5, 6), or the reverse.
