ABSTRACT:
Articulated overhead gate consisting of a series of adjacent and interarticulated panels with their sides facing one another, characterized in that the side of each panel that is uppermost in gate-closed state and faces a preceding panel has a curved surface that is convex in vertical section and the side that is lowermost and faces a subsequent panel has a curved surface that is concave in vertical section, with the result that the mutually facing convex and concave curved surfaces in each pair of adjacent panels demarcate a space that is dictated by the hinge between the panels and accordingly has curved edges, and in that the facing sides shift in relation to each other as they articulate around their associated axis of articulation during the transition from the gate-closed state into the gate-open state in such a way that the space remains but decreases along the direction of articulation during at least part of the transition into the state of maximum articulation.
