Patent

CA 2619629

The guide assembly comprises corner brackets for mounting to the upper corners of a door jamb. Each corner bracket supports an elongated curvilinear track section and an elongated cam track. The curvilinear track section and the cam track each have a central concave portion. The guide assembly further comprises a support bracket which is pivotally mounted to an upper corner of the top panel of the sectional door. The pivoting support bracket has a cam follower which engages and follows the cam track, so that pivoting of the support bracket is responsive to the shaping of the cam track. The assembly is designed to steer the upper edge of the top panel away from the cable drum of a lifting assembly when passing thereby, all with the objective of reducing headroom.

L'ensemble de guidage décrit comprend des supports en cornières à installer aux coins supérieurs d'un poteau d'huisserie. Chaque support en cornière soutient un tronçon de voie curvilinéaire allongé et une voie de came allongée. Le tronçon de voie curvilinéaire et la voie de la came comprennent chacune une partie concave. L'ensemble de guidage comprend de plus une console support installée par pivotement sur une cornière supérieure du panneau supérieur de la porte sectionnelle. La console support pivotante possède un galet de came qui s'engage dans la voie de la came et la suit, de sorte que le pivotement de la console support cause le façonnage de la voie de la came. L'ensemble est conçu pour diriger le bord supérieur du panneau supérieur loin du tambour de câble d'un ensemble de levage, lors de son passage, tout cela dans le but de réduire l'échappée.
