Abstract

L'invenzione riguarda un dispositivo anti - caduta per porte basculanti, porte sezionali e serrande composto da una ruota dentata (15) vincolata e rotante concordemente con una carrucola (14) di rinvio di una fune o catena collegante un contropeso alla porta e da un meccanismo d'arresto basculante (16) interagente con i denti della ruota dentata (15) per bloccare tempestivamente la rotazione della carrucola se la sua velocità di rotazione aumenta incontrollatamente in conseguenza di un guasto al sistema di bilanciamento.FIGURA 3.The invention relates to an anti-fall device for up-and-over doors, sectional doors and shutters composed of a toothed wheel (15) constrained and rotating in accordance with a pulley (14) for returning a rope or chain connecting a counterweight to the door and a pivoting stop mechanism (16) interacting with the teeth of the gear wheel (15) to promptly block the rotation of the pulley if its rotation speed increases uncontrollably as a result of a failure in the balancing system.
