ABSTRACT:
A magnetic catch holds a door in the open position. A cup-shaped metal element is supported for universal rotary motion in a plastic housing mounted on the door. A flat end of the element projects through an open end of the housing and contacts the exposed edge of a rectangular permanent magnet when the door is opened. The magnet is sandwiched between steel plates supported in the rectangular cavity of a plastic housing which is mounted on the floor or wall adjacent the door. A foam cushion resiliently biases the metal element away from the door. The magnet housing is supported on a hollow pedestal extending from a base. Mounting screws are stored inside the pedestal. Threaded plates screwed to the door and wall or floor mesh with threaded open ends of the metal element housing and the pedestal base respectively.
