Abstract: A conversion assembly is disclosed for converting a standard cam lock assembly to a variety of different lock configuration. A kit is also provided which includes a standard cam lock subassembly and different components of a variety of lock configurations which facilitate use of the standard cam lock subassembly with the different lock configuration.

Abstract: A plunger lock assembly having a removable core is provided. The lock assembly includes a housing defining a first longitudinal bore and a barrel reciprocably mounted within the first longitudinal bore between an advanced position and a retracted position. The barrel defines a second longitudinal bore and is operably associated with a plunger. A core is removable mounted within the second longitudinal bore of the barrel and includes a key slot for receiving an operating key. A drive member is positioned within the second longitudinal bore and is movable from an unlocked position to a locked position by operation of the operating key. A retainer assembly is operably associated with the drive member to axially retain the drive member within the second longitudinal bore such that the core is removable from the second longitudinal bore independently of the drive member. A biasing member is provided for urging the barrel towards the retracted position.

Abstract: A tamper resistant lock assembly is disclosed which is configured to prevent keyless operation of the lock assembly. The tamper resistant lock assembly includes a lock housing having a bolt slidably supported therein and a strike. The lock housing is secured to a mounting plate which is adapted to be fastened to a movable member such as a door. The strike is adapted to be fastened to a support member such as a door jam at a position to facilitate engagement between the bolt and the strike when the movable member is in a closed position. The strike includes a C-shaped catch member defining a recess having an opening which is configured to receive an engagement portion of the strike when the movable member is in the closed position. The engagement portion of the strike is also C-shaped and defines a recess.

Abstract: A cable actuation and locking system is provided for operating a plurality of locking devices simultaneously using a single activation device. The cable actuation and locking system includes a lock actuator having an actuation member which is movable between first and second positions, at least one locking device having a movable bolt, a cable assembly interconnecting the actuation member to the bolt, and an activation device which is operatively connected to the actuation member. The activation device is operable to move the actuation member between the first and second positions to move the bolt between locked and unlocked positions. A plurality of locking devices may be provided and interconnected with the actuation member such that operation of the activation device will effect the operation of multiple locking devices simultaneously. In one preferred embodiment, the activation device comprises a key operated rotatable lock core and the device comprises a rotatable plate.

Abstract: A lock down assembly is provided for securing a multi-sided three dimensional device, e.g., a laptop computer, a DVD player, a palm pilot, an MP3 player etc., to a support surface. In one preferred embodiment of the presently disclosed lock down assembly, the assembly includes a lock down member which is adapted to be secured to a support surface, at least one retention member secured to the top surface of the lock down member and a locking member which is removably secured to the top surface of the lock down member. Each retention member and the locking member is configured to prevent movement of a device supported on the lock down member in a particular direction or directions such that the combined effect of the retention member(s) and locking member is to secure a device on the top surface of the locking member. The lock down member includes a plurality of mounting bores for securing the retention member(s) and locking member at multiple locations on the lock down member.

Abstract: A device to be attached to a handcuff or leg iron that disables the existing key that is used to lock and unlock the handcuff or leg iron and replaces it with a locking mechanism that utilizes a non-universal key. The locking mechanism is preferably parallel to the pivot access of the handcuff locking arm and its keyway is spaced above the cheek plates of the body of the handcuff or leg iron and therefore is more difficult to access by the prisoner. The locking mechanism is set by insertion of a key into the same keyway, in a ready to lock position in which the handcuff or leg iron can be tightened but not loosened, or in a triple locked position in which the handcuff or leg iron cannot be tightened or loosened. This triple lock is in addition to the double lock position that is typically offered by the original handcuff or leg iron.

Abstract: A set of handcuffs having an improved locking mechanism. The locking mechanism preferably includes a cylinder lock that is positioned substantially parallel to the pivot axis of the locking arm. The keyway of the locking mechanism is spaced above the plane of the cheek plates of the body of the handcuffs and therefore is more difficult to access by the prisoner than prior art locking mechanisms. The locking mechanism may be set, by insertion of a key into the same keyway, in a ready to lock position in which the handcuffs can only be tightened but not loosened, or in a double locked position in which the handcuffs cannot be tightened or loosened. Preferably, the keyway of the locking mechanism is a restricted keyway such that only keys purchased directly from the manufacturer or someone licensed by the manufacturer or factory can be inserted into the keyway to adjust the setting of the locking mechanism.

The lock assembly includes a housing defining a first longitudinal bore and a barrel reciprocably mounted within the first longitudinal bore between an advanced position and a retracted position. The barrel defines a second longitudinal bore and is operably associated with a plunger. A core is removable mounted within the second longitudinal bore of the barrel and includes a key slot for receiving an operating key. A drive member is positioned within the second longitudinal bore and is movable from an unlocked position to a locked position by operation of the operating key. A retainer assembly is operably associated with the drive member to axially retain the drive member within the second longitudinal bore such that the core is removable from the second longitudinal bore independently of the drive member. A biasing member is provided for urging the barrel towards the retracted position.
