Abstract: A housing closure apparatus for latching a swingable door which covers an opening in a housing. The housing closure apparatus includes a latching mechanism having a latch guide structure with a channel therein for captivating a slidable latch. A latch receiving member is situated on the housing to receive a portion of the latch therein to latch the door closed. In one embodiment of the invention, the latch mechanism exhibits a dual locking capability such that the latch is lockable in a latch closed position against undesired opening due to shock and vibration, and is further lockable in a latch open position.

Abstract: An apparatus and method are provided for removing an electronic module from a connector within a housing. The module is both insertable and removable through an opening within the housing. The apparatus includes a lever arm which is situated mainly internal to the housing except for an end portion of the arm which extends sufficiently far outside of the housing to enable a user to grasp the arm end portion. The lever arm includes first and second engagement points for contacting the module to assist in the extraction of the module from the housing. First, when the user initially pulls on the arm end portion, this action applies a first relatively high level extraction force to the module at said first engagement point. In this manner, the module is removed from the connector via a relatively high first mechanical advantage exhibited by the arm end portion with respect to the first engagement point.

Abstract: A device for carrying and storing pistol shaped appliances such as an air chisel, an electric hand drill, a soldering gun or an electric hair dryer. The appliance is held or clamped to a rigid planar structural member, with the grip and barrel axes oriented substantially parallel to the structural member. The device is carried and stored with the plane of the structural member generally vertical. A reel means can be provided, by a plurality of projections from the structural member near it's periphery for receiving the electric cord or air hose of the pistol shaped appliance as it is wound. The structural member can contain a hand hole for carrying or positioning over a cantilevered support when storing against a generally vertical surface. Projections can be added to the structural member for carrying accessories or retaining the end of the electric cord or air hose.
