Patent

CA 2101376

Electrically operated folding operable walls are provided that are controlled by an electrical operation circuit of the type having a key switch, a control panel, an extend limit switch, a stack limit switch, control relays and a motor. The invention consists of a mechanism for creating an infrared barrier curtain on opposite sides of an operating path of the folding operable walls. Another mechanism is for shutting down the electrical operation circuit of the folding operable walls when a physical obstruction enters into the operating path of the folding operable walls and interrupts the infrared barrier curtain. Still another mechanism is for restarting up the electrical operation circuit of the folding operable walls after the physical obstruction is removed from the operating path of the folding operable walls.

Cette invention concerne des cloisons accordéon escamotables à commande électrique assurée par un circuit du type comportant un interrupteur à clé, un panneau de commande, un limiteur de déploiement, un limiteur de repliement, des relais de commande et moteur. L'invention concerne plus précisément un dispositif générateur de rideaux de faisceaux infrarouges de part et d'autre du trajet de déploiement/repliement des cloisons accordéon. Un deuxième mécanisme est prévu pour couper l'alimentation électrique du circuit de commande lorsqu'un élément matériel coupe la trajectoire des cloisons et, par conséquent un des faisceaux infrarouges. Un troisième mécanisme sert à remettre le circuit de commande en fonction lorsque l'obstruction matérielle est enlevée de la trajectoire susmentionnée.
