Abstract (en)
[origin: EP0151427A2] 1. Spring control device for a pretensioned torsion spring of a gate, a door or the like, in particular as a weight-balancing spring for a one-or multi-part overhead movable door leaf or an armoured roller door, to prevent the door leaf from falling down in the event of a breakage of the spring, in which, for at least one of the two end regions (11) of the spring (3), a tension sensor (13) is provided, said tension sensor being biased by said spring in one direction in the biased condition of the spring, and in the opposite direction in the event of a breakage of the spring, solely by the reaction force of the spring, to release a locking device for the door leaf (7, 9).
