Abstract: A theft deterrent enclosure that eliminates unauthorized access is disclosed. The enclosure includes a door assembly having three sides and a wrapper assembly having three sides that mate to form a lockable enclosure. A key lock cylinder is mounted in a lock opening of the door assembly such that it blocks the lock opening in a locked position. A keyed interface operates a fastener, such as a compression latch, threaded coupling or lock plate, which is mounted on the door assembly such that the fastener secures the door assembly and the wrapper assembly in a closed position. The keyed interface is positioned on an interior side of the enclosure that is opposite and aligned with the lock opening. A guide sleeve is positioned inside the enclosure that guides a security keyed tool inserted through the lock opening toward the keyed interface.

Abstract: A thread retained security bolt system has a bottom collar and a top collar, the bottom collar fixed to one element of an enclosure and the top collar affixed to a mating element of the enclosure. The top collar carries a minor part of a securing bolt bearing surface and the bottom collar carries a major part of the securing bolt bearing surface and when the mating element of the enclosure is brought into engagement with the one element of the enclosure, the minor part is aligned with and contiguous to the major part upon joinder of the top collar with the bottom collar. A bearing surface of a head of a bolt is then moved into engagement with the minor part and the major part to secure the one element to the mating element.

Abstract: A door lock system for enclosures is provided which includes a screw drive mechanism releasably mounted on a back plate member and coupled via threads to a threaded locking member to linearly drive the locking member to engage with a receptor on an enclosure frame to lock the enclosure. A controller unit has an integrated circuit configured to control the operation of the screw drive mechanism and report the status of the door to a central location. A position switch is used to indicate whether the door is open or closed so that the controller unit can automatically engage the screw drive mechanism to lock the door after a preset time delay. A keypad allows a user to enter a code to unlock the door. A radio in the controller unit permits wireless communication to report status and to allow central command control over the doors.

Abstract: A wireless lock assembly includes a latch assembly that includes a wireless, electrically operated latching component, and a manually movable latching component. The wireless, electrically operated latching component is movable between activated and inactivated positions. The electrically operated latching component will remain in the activated position for a predetermined period of time, after which it will return to the inactivated position. The lock assembly also includes a handle assembly that is manually movable from a non-enabled position into an enabled position when the electrically operated latching component is moved to its activated position. When the handle assembly is in its enabled position, it can be manually moved so as to move the manually movable latching component from a locking condition to a releasing condition. The handle assembly can be manually moved from its non-enabled position to its enabled position by manual engagement and depression of an exposed surface portion thereof.

Abstract: A wedge bar locking mechanism is provided including a locking pin, a bracket and a wedge bar. In operation, the locking pin and wedge bar are mechanically coupled such that rotation of the locking pin results in translational motion of the wedge bar. The wedge bar and locking pin are received in the bracket which prevents rotational motion of the wedge bar and translational motion of the locking pin. In a preferred embodiment, the bracket has retaining tabs permanently attached or integral thereto, and extending radially inward of a longitudinal cylindrical pathway for accommodating the locking pin therein. The tabs are received within a reduced diameter portion of the locking pin to prevent translation thereof.

Abstract: A locking system comprising a locking fastener having tamper-resistant features, and a special key having a bit at one end for engaging a socket in the head of the locking fastener to rotate the latter. The internal configuration of the socket corresponds to an external configuration of the bit, and the corresponding contour of the socket prevents the fastener from being turned by tools other than the special key. The fastener may have left-handed threads on its shaft and its head may be recessed in a counterbore in a closure part to prevent gripping tools from gripping an external surface of the head. The configurations of both the socket and the key may readily be made by economical metal working techniques.

Abstract: A lock operable by a key between a locked condition and an open condition, the lock having a fastener for releasably securing the lock to an object, the fastener being movable between a retracted position wherein the lock is in the open condition and an extended position, a spring for biasing the fastener to the retracted position and an enclosure having an opening adapted to allow the insertion and removal of the key from the lock when the lock is in the locked condition and to prevent the removal of the key from the lock when the lock is in an unlocked condition.

Abstract: A pop-up handle assembly having a base with a mounting panel and a tubular housing and a handle with a tubular stem axially movable within a hollow sleeve rotatable within the tubular housing. The handle mounts a key-plug which is depressable to release a lock pin carried by the tubular stem from engagement with a shoulder in the tubular housing whereby the handle pops-up to an operative position under the urging of a spring. The key-plug is rotatable between locked and unlocked positions and into an unlocked position can be depressed to release the handle for movement without the use of a key. The handle assembly has provision for pop-up of the handle from the inner side thereof to free the handle for rotation regardless of whether the key-plug is either locked or unlocked.

Abstract: A gate locking system for securely locking a rolling type gate in a closed position within an opposing pair of U-shaped channel guide rails. The guide rails include aligned apertures formed through opposing front and rear walls. The gate also includes an aperture which is aligned with the guide rail apertures when the gate is in the closed position. A guard plate is positioned exteriorly of the guide rails and also includes an aligned aperture. An elongated member of a lock is inserted through the various apertures to lock the members together in the closed position. The head of the lock is retained exteriorly of the guard plate while the distal end of the lock extends beyond the rear wall of the guide rail. A securing member cooperates with an extended end of the elongated lock member to retain the lock in a clamped position between the opposing walls of the guide rail so that the closed gate is captured therebetween. The securing member is under the operative control of a rotatable portion of the lock.

Abstract: A wall type security box sized to fit between, and to be fixed to, adjacent studs in a wall opening. The box is locked by a lock device in the form of an elongated rod having a key cylinder on one end and screw threads on the other end. After closure of the security box's door, and by manually gripping a key in the lock device's key cylinder, the elongated rod is, first, extended through a grooved bore in the box's face wall on one side of the box's access opening, second, extended through a through bore in the door, and third, rotated into threaded relation with a threaded bore in the box's face wall on an opposite side of the access opening. Preferably these bores are all axially aligned one with the other when the door is closed. The key is then removed to extend the cylinder's spring loaded lugs into latching relation with axial grooves in the grooved bore below the access opening, thereby preventing further rotation of the elongated rod and locking the security box.
