Abstract

L'invention concerne un tourniquet rotatif de type anti-pincement, comprenant un cadre (20), une structure de bras tournant disposée sur le cadre, et un détecteur (12). La structure de bras tournant est entraînée par un mécanisme d'entraînement pour tourner de telle sorte que la structure de bras tournant entraîne un disque de porte (19) pour dessiner une forme de secteur circulaire. La structure de bras tournant comprend un bras tournant d'entraînement (5) fixé à une extrémité d'entraînement du mécanisme d'entraînement et un bras tournant entraîné (6) relié au disque de porte (19) par l'intermédiaire d'un axe. Le bras tournant d'entraînement (5) et le bras tournant entraîné (6) sont disposés de manière à permettre un mouvement limité. Lorsque le disque de porte (19) est bloqué par un objet, le mécanisme d'entraînement met en mouvement le bras tournant d'entraînement (5) et le bras tournant entraîné (6), puis le détecteur (12) détecte le déplacement et contrôle le mécanisme d'entraînement de façon à arrêter le fonctionnement ou à fonctionner en sens inverse. Le tourniquet rotatif de type anti-pincement permet le freinage d'un moteur électrique par déplacement mécanique lorsqu'un défaut infrarouge se produit.
