摘要:
A lock assembly (30, 30′) is provided that includes a housing (32), a rotary bolt (36) or a translating bolt (36′), and a bolt blocker (38) that moves between a blocking position blocking movement of the bolts (36, 36′) and an unblocking position permitting the bolts (36, 36′) to move to a retracted position. The lock assemblies (30, 30′) are resistant to shocks being applied to the locks assemblies (30, 30′) in an effort to open the lock assemblies (30, 30′) without authorization.

In a recodable lever tumbler lock such as used with a safety deposit box lock, a coding device (17) and a recoding pin of particular configuration are caused to interact with remaining components of the lock mechanism of more conventional instruction. When the lock is activated to its normal retracted position, one end of the coding device functions as a stop abutment and engages a waist portion on the recoding pin whereby another part of the coding device engages a hook means provided on the periphery of a dog (7) included in the lock, and the dog can be rotated only through about 150 ° with the ordinary key. When the lock is to be recoded so as to work with a different key, the lock is first activated to its locking mode with the door open, and the recoding pin is moved to a second end position by manual manipulation. In this second end position, the end (17e) of the coding device is prevented from entering a waist on the pin and therewith enables the dog to be rotated through 180 ° and the key (5) to be replaced with a new key (6). At the end of this locking movement, the coding device is released from its engagement with the fences and recoding of the lock to the new key takes place and the coding device locks the fences (15) in their newly adopted positions. The recoding pin (21) is returned automatically to its normal position.
摘要:
A local and remote lock management system including at least one electronic control device that allows electronic/electromechanical locks with an electronic keypad to be managed locally and remotely from a network supporting the TCP/IP protocol, and a remote lock management program for locally and remotely managing electronic/electromechanical locks through the at least one control device. Each lock is associated with its own control device having its own IP address. In a directly-connected configuration, the system has a series of electronic locks, the control devices for each lock acting as a Web server for any Internet/Intranet client that wants to connect remotely to it. In a master/slave configuration, the system has a series of locks, only one of which has a web server, all locks are connected to the network, and the user accesses the parameters of all the other control devices through the master control device.
摘要:
A dead bolt lock (214) automatically blocks the extended bolt (204) to prevent externally-applied force from thrusting the bolt (204) back into the lock case (100), and in the event of physical attack the lock responds by prolonging or perpetuating the deadbolt blocking condition. A push-pull lock has a bolt whose motion in both directions is stopped in response to detection of a rise in motor current above a certain level: a cushioning arrangement allows the current-limiting features (600) to be implemented without risk of damage to the motor (202), gear teeth or other drive components. A re-locker arrangement includes an angled flange that is part of a motor-supporting bracket (206); when forcibly pressed, the flange breaks plastic pins (920) to release a spring-biased re-locker wire (950) to block the bolt from being withdrawn. The system also provides a position sensor switch (692), a keypad tampering detection and response system (646), remote enable/disable unit (5), duress detection and response unit (7), low-battery sensing arrangement (600) and bolt extension indication, adjustable bolt throw and audit trial features.
