Abstract (en)
[origin: EP0894936A1] The anti-drop mechanism for a roller shutter door mounted on a horizontal shaft (1) comprises a fixed flange on the shaft and an adjacent rotary flange fixed to the shutter so that it rotates relative to the fixed flange as the shutter moves. The rotary flange has a number of centrifugal locking elements (25,26,27) in the form of spring-loaded and pivoted levers with end claws (25a) which engage with apertures (16,17) in a rim (12) on the fixed flange surrounding the levers when the normal operating speed of the shutter is exceeded.
