DEVICE FOR LOCKING DOOR AND WINDOW LEAVES

摘要

The invention relates to a device for locking at least one leaf pivotally mounted in a frame by means of hinge plates which additionally permit the displacement of the leaf in translational motion with respect to the frame. The hinge plates are oriented parallel to the frame and means providing a connection between the hinge plates and the frame are provided for guiding the movement of displacement of the hinge plates so that said movement is carried out in the plane of said hinge plates and has an oblique component with respect to the vertical along at least a part of its path, said movement being controlled by an external lever.
