Hinged door leaf with opening mechanism - has linkage with rod and two bars coupled to rotary drive

Abstract

Abstract The hinged door leaf has an extension rod hinging on it and on a drive mechanism, being particularly for garages, factories etc. The rod (a) is part of a linkage with a first bar (B) hinging on its and furthest from the door (T) and at the other end (4) on a fixed point. At an intermediate point of the first bar a second bar (C) hinges, the other end of which is driven by the opening and closing mechanism along a circular path in a plane at right angles to the hinge axis. The path intersects the plane passing through its centre and parallel to the door hinge axis, and also the axis of the second bar both when the door is open and shut.
