Abstract: The present invention provides an improved electric lock that allows for electrically controlled retraction of latch bolt to allow for opening of the door in which the lock is installed. The components that allow for retraction are primarily internal to the lock and have means for conducting electrical signals to the lock to allow for remote control of the latch retraction. In some embodiments, the locks comprise an electrically controllable actuator and at least one retraction lever configured to retract the latch bolt against an applied bias. In other embodiments, the actuator can be housed within a separate housing can be configured to retract the latch bolt directly without using a retraction lever.

In some embodiments, the locks comprise an electrically controllable actuator and at least one retraction lever configured to retract the latch bolt against an applied bias. The actuator can be configured with various other internal components such that movement of the other internal components in one direction, such as toward the actuator, causes movement of the latch bolt in the opposite direction, such as away from the actuator. This opposing movement can allow for different electrical arrangements within different locks having relatively small internal spaces.

Abstract: The device includes an electromagnet, a bracket for holding the electromagnet in a door frame to force the opening therein, an electrical conduit for connecting the electromagnet to a power source, an armature magnetically attracted to the electromagnet when the latter is energized, a connector for holding the armature on a door edge in the frame for adjustable movement towards the electromagnet and a lock component for the device. The lock component comprises one or more ledges at the periphery of the electromagnet and/or armature pair projecting towards and engageable with the other(s) of the pair when the armature is magnetically attracted to the energized electromagnet. This occurs when the armature and electromagnetic are in line with each other, the armature being free to move toward the electromagnet. Unlocking is effected by deenergizing the electromagnet and allowing the armature to retract by gravity or spring action, so that the lock component also moves out of the descirbed engagement.

Abstract: The assembly includes a door with rotatable door handle connected thereto, and a primary door locking mechanism. The door is hinged for opening and closing in a frame disposed in an entry way. The door includes a handle hub lock having a hub locking plate around the handle hub, a protrusion extending from the locking plate, a bolt member having a recess adapted to receive the protrusion, a bolt biasing mechanism, and a biasing force reversal mechanism for causing the bolt member to move in a direction opposite to the direction in which the bolt biasing member moves. The biasing mechanism preferably includes a plunger extending from the leading door edge toward the door jamb and biasable thereby, during door closing, against the bolt to move it into the locked position, and a spring connected to each of the plunger and bolt member. In one embodiment, magnets magnetically bias the slide bolt member to the desired locked or unlocked position.

Abstract: An improved door locking and monitoring assembly is provided which is power activated. The assembly comprises a housing disposable in a door frame and defining a passageway which has a bolt slidably disposed therein and lockset means in the door member. A lever is pivoted in the housing. The lever is L-shaped, with a spring biased vertical arm below it. The rear of the latter is urgeable upwardly by a ball to pivot the lever and move the bolt forward into the locked position. The ball is urgeable upwardly by a solenoid actuated plunger. The biased L-shaped arm has the arms thereof pivoted allowing relative angular movement. An extension on one of the arms is forced into an opening in the housing when the bolt is fully extended to lock-set the bolt. When the bolt moves into the locked position, a member on its rear end closes a powered switch to signal this condition.
