Abstract: A collapsible, dish shaped assembly, for example, for use with a satellite. The dish shaped surface is assembled from two sets of rigid panels. The first set of panels is rotated into position on hinges, which attach the panels to a base. The second set of panels is then rotated into position, also on hinges at the base, such that the second set of panels fill in the spaces between the panels of the first set. A latch connects each pair of adjoining panels. The latch comprises a protrusion which slides into a corresponding cavity. The resulting latch is resistant to lateral force. The latching process is facilitated by magnetic forces, which also add to the final latching force. The latches can be disengaged by jacking screws.

Abstract: A security closure for handguns including a rigid metal box having a front opening with a door pivotally attached to one side thereof and having a push-button combination locking mechanism. Disposed within the enclosure is a holster or other gun-holding receptacle which is pivotally mounted to the inside of the box and is adapted to swing outwardly as the door is opened so as to present the handle of the gun to one opening the door.
