Abstract

The roller door or grille is designed to roll up round a shaft (1) set horizontally above the doorway when raised. It is equipped with a balancing spring to take the weight of the door/grille. A safety mechanism prevents it from falling in the event of the balancing spring breaking. The safety mechanism is positioned between the shaft and the balancing spring. A spring-loaded catch (60) flies outwards if the balancing spring breaks, engaging with a horizontal member of the door/grille and preventing it from dropping suddenly. The catch is held in its passive position by a retaining peg (63) on a moving hub (53). It is also connected to the hub by a spring (65). In the event of the balancing spring breaking the hub, it is moved by the spring (65), releasing the catch so that it instantly stops the door/grille.
