Opening device for retractable flap, e.g. for smoke outlet, heating or ventilating flap or lighting shutter, e.g. for vehicle, includes driving arrangement that frees up the maximum available space during flap displacement

摘要

The opening device for a flap (1) having four rollers (9) in the angles on hidden top faces to guide the flap during displacement, includes two pairs of C-shape sliders (10), each having two right sliders perpendicularly fixed to one another, two telescopic arms (11) and a motorized rotating arm, whose two ends are mounted on bearings mounted on solid flanges of the flap. One of the bearings is fixed to one telescopic arm so that the slider at the opposite end is rotatable about an axis fixed to the middle at an angle intersecting the two sliders, making the kinematic arrangement free up the maximum amount of space during movement of the flap.
