Abstract: A locking system for a loaded handgun that prevents the handgun from being removed from a housing until a combination lock is unlocked. The housing is constructed of a material such as steel or a high impact resistance polymer, capable of preventing penetration of a slug fired by the handgun. The combination lock is either an illuminated keypad or a bio-metric sensor. In one embodiment, the combination lock actuates a locking member that prevents the handgun from being removed and extends behind the trigger, so that the handgun cannot be fired. In another embodiment, the combination lock secures a locking member in a position that prevents a holster containing the handgun from being pivoted outside an internal cavity within the housing. While the handgun and holster are locked inside the internal cavity, the handgun cannot be withdrawn from the holster. When the proper combination is entered, the locking member releases the holster, and a spring element pivots the holster free of the internal cavity.

Abstract: Eyewear having easily removable lenses is provided with a frame that defines a first lens receiving recess on one side of a lens opening and a second lens receiving recess on a second side of the lens opening. Each lens has a first tab portion which corresponds with the first recess and a second tab portion which corresponds to the second recess and is mounted by placing the first tab portion in the first recess and the second tab portion in the second recess. Engagement between the respective tab portions and recesses maintains the lenses in the mounted position. To more securely lock each lens in position, a pivot member having a locking tab can be pivoted into a locking position in which the locking tab engages the lens.

Abstract: An environmentally sealed electronic test instrument having a three-part case enclosing an electronic testing circuit of conventional design. The three parts are open-ended top and bottom parts, and an end part covering the open ends of the top and bottom parts. The top and bottom parts have adjoining sidewalls between which is positioned a first resilient seal. Respective inwardly extending flanges are formed at the open ends of the top and bottom parts. The flanges are received by a second, U-shaped seal that is, in turn, received by a U-shaped channel formed along a marginal edge of the end plate. A pair of fingers integrally formed in the second gasket project into the U-shaped channel and are positioned between the first seal and top part of the case. The side marginal edge of the bottom part of the case are recessed within the sidewall of the top part of the case to enclose the first gasket.

Abstract: A zero insertion force receptacle for a battery powered device including a battery storage area having a pair of parallel battery cradles. A pair of stationary contacts are positioned at the first end of the cradles and a pivotable connector is positioned at the second end of the cradles. The pivotable connector includes a pair of actuator arms which are engaged by a shoulder on a removable cover as the cover is closed. The shoulder displaces the actuator arms and causes the pivotable connector to rotate about a pair of pivot pins to bring a pair of contact arms into engagement with the batteries. As the closing of the cover increases, the actuator arms are pivoted further about the pivot pins to increase the force between the contact arms and the batteries. In the preferred embodiment, the actuator arms are linked to the contact arms by spring sections.
