| 070100500 | ATTACK-ACTUATED DEFEATING MECHANISMS | 9 |
| 20090211315 | SECURITY CONTAINER WITH LINKED PRIMARY AND SECONDARY SECURITY FEATURES - A security storage container has a primary security feature that is adapted to be locked and unlocked with an appropriate key. A secondary security feature is activated when the security storage container is opened without first unlocking the lock with the key. In one embodiment, the secondary security feature includes prongs that are moved to an extended position when the primary security feature of the container is defeated. In the extended position, the prongs will at least damage the item of merchandise protected by the security storage container. The extended position of the prongs may also further lock the item of merchandise within the security storage container. | 08-27-2009 |
| 20110192200 | SECURITY CONTAINER WITH LINKED PRIMARY AND SECONDARY SECURITY FEATURES - A security storage container has a primary security feature that is adapted to be locked and unlocked with an appropriate key. A secondary security feature is activated when the security storage container is opened without first unlocking the lock with the key. In one embodiment, the secondary security feature includes prongs that are moved to an extended position when the primary security feature of the container is defeated. In the extended position, the prongs will at least damage the item of merchandise protected by the security storage container. The extended position of the prongs may also further lock the item of merchandise within the security storage container. | 08-11-2011 |
| 20110203326 | Lock device - A lock device includes an actuating lever pivotally engaged in a lock housing for actuating a deadbolt of a latch device, two rotary mechanisms pivotally engaged in the housing and each having a rotary member pivotally engaged in a casing for coupling to an outdoor handle and an indoor handle, and the rotary member of one of the rotary mechanisms is secured to the casing for allowing the rotary member and the casing of the rotary mechanism to be rotated relative to the lock housing with the indoor handle only, and for preventing the outdoor handle from being brutally rotated by the unauthorized persons and for preventing the lock device from being destroyed or damaged by the unauthorized persons. | 08-25-2011 |
| 20110289985 | TAMPER RESISTANT LOCK - A tamper resistant lock is provided. The tamper resistant lock comprises a primary locking mechanism for locking and unlocking the tamper resistant lock with an appropriate key. A secondary locking mechanism is engaged and prevents unlocking when a sufficient force is applied to the tamper resistant lock. The force may be the result of driving a screwdriver into a keyway of the lock in an attempt to forcefully unlock the lock. | 12-01-2011 |
| 20130042657 | RELOCKING MECHANISM - A relocking mechanism that blocks the path of a bolt within a lock assembly is presented. The relocking mechanism comprises a breakaway member that is repositioned when the lock assembly is attacked by some mechanical means, such as impact applied via a hammer and punch to the lock housing through a spindle hole in a door. The breakaway member prior to attack holds a preloaded relocking plunger clear from bolt movement. When the breakaway member is repositioned upon attack, the plunger is free to move under a biasing force into position so as to block the bolt thus keeping the lock in a secure locked state regardless of the state of the locks default blocking mechanism. | 02-21-2013 |
| 20130081434 | CABINET LOCK FOR USE WITH PROGRAMMABLE ELECTRONIC KEY - A cabinet lock for protecting merchandise within a merchandise display cabinet having an inner door and an outer door. The cabinet lock includes a strike plate affixed to the inner door and a lock housing affixed to the outer door such that the cabinet is in a locked configuration that prevents access to the merchandise when the lock housing is operably engaged to the strike plate. A programmable electronic key communicates a security code with the cabinet lock and transfers electrical power to the cabinet lock to operate a lock mechanism between the locked configuration and an unlocked configuration. An indicator is provided for indicating whether the cabinet lock is in the locked configuration or the unlocked configuration. The indicator includes a first segment and a second segment that can be energized to visually indicate the status of the cabinet lock. | 04-04-2013 |
| 20130233031 | DISENGAGEABLE LOCK - The invention relates to a lock ( | 09-12-2013 |
| 20140165667 | PICK-PROOF DOOR AND METHOD FOR PROTECTING DOOR SAFETY - In a method for protecting safety of a door. The method obtains a current image captured by an image capturing device installed in a key holder of a lock of the door, detects an object in the current image, and compares the current image with a preset key template when the object has been detected in the current image. The method further activates a safety guard unit of the door using a driving unit of the door when the current image does not match the key template, and locks a slip bolt of the safety guard unit. | 06-19-2014 |
| 20140196509 | Attack-Thwarting Cylindrical Lockset - Mechanisms are provided to thwart an overtorquing attack on a cylindrical lockset. The cylindrical lockset comprises a lock cage, a split retractor assembly, and a torque-attack-activated spring-loaded blocker assembly coupled to the lock cage. The blocker assembly is set to a default non-blocking configuration. An overtorquing attack triggers the blocking assembly into a blocking setting. When in the blocking setting, the blocking assembly blocks movement of at least an outside door portion of a retractor assembly from translating into a latch-retracting position, but does not block the inside door handle from retracting the latch. A new split retractor assembly is also provided. | 07-17-2014 |
