ABSTRACT:
A door which may undergo rotational as well as vertical and horizontal movement relative to a door frame is provided. The door is provided with a lifting means which includes a slide plate which may be vertically displaced relative to the door. A lever is pivotally mounted on the door with one end having a roller which engages a slot on the slide plate and the other end having a roller which engages a block mounted on the door frame. The vertical displacement of the slide plate causes the lever's roller to ride in the slot until the roller reaches the end of the slot at which point the slide plate causes the lever to lift the door relative to the door frame. To accommodate such door movement, the door is provided with a hinge which includes a clevis mounted on the door frame which includes a lower section having a bearing surface and an upper section having an internal cavity. The internal cavity includes an internal shoulder area and slots which communicate with the lower area of the upper clevis section. A hinge member is affixed to the door and includes a body having an upwardly extending portion of a diameter less than that of the internal cavity of the upper clevis section. The upper section of the hinge member includes radially extending lugs which may engage the internal shoulder of the cavity. As such, in the upper position the lugs ride on the internal shoulder while in the lower position the bottom of the hinge member rides on the bearing surface of the lower clevis section.
