Abstract: In an electric door lock, a spindle with a manually operable rotary knob is connected operably to a dead bolt, and has a spindle coupling plate sleeved non-rotatably thereon, and a gear plate unit sleeved rotatably thereon. The spindle coupling plate is provided with a ball member which is biased to project from the spindle coupling plate and engage one of a plurality of angularly displaced ball recesses formed in the gear plate unit.

Abstract: The locking device (10) for doors, in particular of vehicles, has an inside door opener and an outside door handle (12) which can be used to actuate at least one lock for locking the door. Locking devices of this type are conventionally very complicated mechanically, since the mechanical connection between the outside door handle (12) and the lock is meant to be uncoupled as a function of various functional positions. In order to reduce the mechanical complexity, only the inside door opener should act mechanically on the lock, and the outside door handle (12) should act via an electric control on an actuating drive (18), which actuates the lock. In this case, the opening command is instigated only if at least one defined allowable precondition is present. The required additional functions of locking devices can very easily be controlled by the electric control, so that additional mechanical elements are not required.

Abstract: A lock for safes and other security devices is disclosed having a case mountable on the inside of a safe door. A locking bolt in a slidable relationship within an opening in the case, moves between locked and unlocked positions. A gate, constrained in slidable relationship by and with the locking bolt, normally prevents the locking bolt from moving out of the locked position. An internal case extension obstructs the gate, when the lock is not activated, preventing the locking bolt from moving towards the unlocked position. A camming member, pivotally attached to the locking bolt, repositions the gate allowing the locking bolt to move out of the locked position. A solenoid driven armature, linked to the camming member and connected to the locking bolt, pivots the camming member and moves the locking bolt to the unlocked position. The locking bolt is held in the locked position when not activated by a spring.

A lever armature, which can be connected to the locking slide, can be connected to the locking slide such that it can be optionally switched over for closed-circuit or open-circuit operation. The locking device permits an arrangement adaptable to various installations, as well as monitoring of the open and closed states and optionally closed- and open-circuit operations.

Abstract: An anti-tamper locking assembly for locking a position of a block, such as a locking bolt in an electronic lock, electrically moves a pin to engage or dis-engage the block. When dis-engaged, the block can be moved and access or the like can be made. The pin is selectively moved electronically in order to allow access, entry or the like. The pin can be moved with, e.g., a solenoid. The pin has an overhanging portion, or a head portion. In order to prevent an individual from forcing the pin into an un-locked position, the head portion operates in conjunction with at least one spring-arm member and a blocker which are fixed to the block to prevent a user from being able to strike the device with a hammer or the like to "temporarily" move the pin to a position allowing the block to be moved and access or the like to be made.

Abstract: An electric strike has a pivoting locking member for locking an electric strike in the closed position. The locking member is pivoted between the locked and unlocked positions by a low current motor. A drive pin pivotally engages the locking member. The motor rotates a roll pin threadably engaging the coil faces of a spring mounted to the drive pin. Rotation of the motor compresses or expands the spring to axially move the drive pin and thereby pivot the locking member between the locked and unlocked positions.

Abstract: A remotely controllable lock includes a housing, a motor mounted in the housing, and a control device mounted in the housing for activating the motor. A gear train is mounted in the housing and driven by an output shaft of the motor and has a drive gear. A turn knob has an axle rod extended through an axle tube mounted to the housing. The axle rod is engaged with a driving member for driving a dead bolt of the door lock. When the turn knob is manually turned through a pre-determined angle, the movable plate is moved from a first position representing one of a locked status and an unlocked status of the dead bolt to a second position representing the other one of the locked status and the unlocked status without actuating the drive gear.

Abstract: An electromagnetic lock assembly employs a switch which detects an attempt to open the door. The armature is biased tow the door by a spring acting between a mounting bolt for the armature. An actuator protrudes from the electromagnet bonding face and engages against the cap of the mounting bolt. A switch may thus be actuated while the electromagnetic bonding between the armature and the electromagnet is maintained.

Abstract: A method and apparatus is provided for securing trailer doors against tampering. In one exemplary embodiment, a locking device is mounted on the inside of a trailer door. The device includes a locking bolt which is selectively operated by a pneumatic valve in response to a signal selectively generated by an operator. In the example, the locking device is normally in a locked position and the locking bolt is effective to secure the trailer doors to the frame of the trailer. An operator selectively causes the generation of an "unlock" signal through the use of a wireless control device. The unlock signal, in turn, operates upon an electro-pneumatic valve device to effect an application of locally available high air pressure to a locking bolt actuator assembly. The air pressure is sufficiently high to effect the movement of a relatively heavy locking bolt out of a locking position, at which time the trailer doors may be opened for access to the trailer load.

Alternatively, the system 10 can lock door 14 of building 12 by mounting system 10 on or in either door 14 or building 12. System 10 can cooperate with other security systems in the building, including a siren 34 or a window sensor 46.
