  • Publication number: 20140159395
    Abstract: An actuator-controlled strike comprising a housing disposable within a doorframe and including a cavity for a spring latch and a dead latch of a mortise-type lockset. A keeper is pivotably mounted within the chamber to engage the spring latch. A pivotably mounted kicker cooperates with the keeper. A pivotably mounted dead latch release is supported by the keeper when the spring latch is within the strike. The keeper is released by the actuator and rotates into a position to ramp the spring latch out of the strike, also allowing the dead latch release to release the dead latch into the cavity, allowing the spring latch to be ramped out of the strike. Pivoting the keeper causes the kicker to urge the spring latch onto an exit ramp on a face of the keeper. The dead latch release can be installed in a plurality of different locations in the housing.

  • Publication number: 20130328332
    Abstract: An actuator-controlled strike comprising a housing disposable within a doorframe and including a chamber for receiving a spring latch and a dead latch of a mortise-type lockset. A keeper is pivotably mounted within the chamber to restrain the spring latch. A pivotable spring latch lifter is positively driven by the keeper, and a pivotable dead latch release platform is supported by the keeper when the spring latch is locked within the strike. The keeper is released by the actuator and then may be rotated which causes rotation of the dead latch release platform, allowing the dead latch to enter the chamber. The keeper positively drives the spring latch lifter to lift the spring latch onto the external ramp of the strike. In an alternate embodiment, an internal ramp feature may be used instead of the spring latch lifter to positively lift the spring latch out of the chamber.

  • Patent number: 8562040
    Abstract: An electric lock for remote access control to a container wherein a U-shaped latch is mounted on a door in alignment with a slot in a housing mounted in the container. Upon closure, the latch enters the housing to engage a slotted keeper therein and causes rotation of the keeper. Rotation of the keeper causes a release lever to engage a stepped protrusion on the keeper and secures the keeper and latch. Activation of a solenoid or drive motor coupled to the release lever permits withdrawal of the latch from the housing. The axes of rotation of the keeper and release lever are located to greatly reduce the impact of pre-release forces to the door.

  • Publication number: 20130241680
    Abstract: A standard solenoid body and coils are combined with a non-magnetic armature tube containing a permanent magnet, preferably neodymium. The magnet is located in one of three positions within the armature. When biased toward the stop end of the solenoid, it may be configured to act as a push solenoid. When biased toward the collar end of the solenoid, it may be configured to act as a pull solenoid. In either case, no spring is required to return the armature to its de-energized position. Positioning the magnet in the middle of the armature defines a dual-latching solenoid requiring no power to hold it in a given state. A positive coil pulse moves the armature toward the stop end, whereas a negative coil pulse moves the armature toward the collar end. The armature will remain at the end to which it was directed until another pulse of opposite polarity comes along.

  • Publication number: 20130067969
    Abstract: An electronic wireless locking system comprising an external assembly and an internal assembly disposable on respective sides of a door or drawer. The external assembly includes a cover housing, a knob having a shaft, a card/credential reader, a status indicator, a wireless communication capability, a wire harness and a jump port plug. The internal assembly comprises a rotation link matable with the external shaft, a latch bolt, a circuit board and controller, and a locking mechanism including a rack and pinion gear set linking the rotation link with the latch bolt. A blocker inhibits the latch bolt from unlocking until authorized to rotate 90°, permitting the latch bolt to be withdrawn from a strike plate by manual rotation of the knob. An optional mechanical key override feature may also be provided. The system may further include a preload sensor and a device locked sensor.

  • Patent number: 8047585
    Abstract: A surface mounted electric strike for use with an exit device such as a rim panic exit device. The electric strike has a housing with at least one keeper pivotally mounted to the housing. Each keeper has an associated cam with a detent. Release pawls engage detents on the cam in the locked position. A solenoid-operated unlock bar has stops, the position of which establishes whether the keepers are in a locked or unlocked position. The electric strike can be installed in either a fail safe or fail secure mode by locating the stops when the solenoid is de-energized in either a position which blocks or releases the release pawls. Other arrangements for establishing a selected operational mode include use of dual solenoids, use of dual locking bars and reversible release pawls.

  • Patent number: 7980603
    Abstract: A locking system wherein the latch is rotatable to provide either a first beveled surface for use as a ramp in latching or a second beveled surface for use as a ramp in unlatching. An entire latch module may be rotated about its axis by a rotary solenoid to achieve this function, and the first and second ramping surfaces are physically the same surface repositioned by rotation 180°. Alternatively, a releasable latch has a beveled surface for engaging a striker plate during bolt entry and a non-beveled surface for locking. The latch is pivotable to allow the non-beveled surface to become the beveled ramp for unlocking. The releasably pivotable latch mechanism may be used with a deadlock. The mechanism is readily incorporated into a rim exit device for releasably securing a door such as an emergency exit and may be actuated either electrically or manually.
