Abstract
A foldaway security shutter (1) is described, comprising a plurality of transverse elements (2) articulated together by means of connecting-rods (3) pivoted at the ends (4) of said transverse elements (2), two lateral uprights (6) within which the ends (4) of the transverse elements (2) and the connecting-rods (3) slide between a closed position in which said transverse elements (2) extend along the uprights (6) and an open position in which the transverse elements (2) are gathered in an upper box (8), and operating means (7) for the transverse elements (2). Said operating means (7) are equipped with a toothed wheel (9) operated by an electric motor (17), suitable for engaging the internal teeth (10) of rack connecting-rods (3), causing the upward or downward movement of the transverse elements (2).
Claims8
A foldaway security shutter comprising a plurality of transversal elements articulated between them by means of connecting rods hinged by the extremities of said transversal elements, two lateral uprights inside which the extremities of the transversal elements and the connecting rods slide between a position of closure in which said transversal elements are outstretched along the uprights and an opening position in which the transversal elements are gathered in a superior box, and operation means of the transversal elements, characterized in that the box houses a horizontal inferior guide provided with a plurality of consecutive notches suitable for the temporary anelastic retainment of transversal elements.
A method of folding in a box with an horizontal guide of transversal elements connected by connecting rods of a foldaway security shutter, characterized in that it provides the temporary anelastic retainment of transversal elements in a plurality of consecutive notches obtained in the horizontal guide, a transversal element being removed from the notch in which it is retained by a following transversal element which occupies the notch left free by the removed transversal element which moves towards a subsequent notch of temporary anelastic retainment.
