An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to retain position to permit removal.

Electro-mechanical lock core

A removable lock core for use with a lock device having a locked state and an unlocked state is disclosed. The removeable lock core may include a cam member tailpiece which is moveable between a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which permits removal of the removeable lock core from the lock device which corresponds to the lock device being in the unlocked state. The removeable lock core may include an electro-mechanical drive assembly which in a disengaged state is decoupled from the cam member tailpiece and in an engaged state is coupled to the cam member tailpiece. A cam lock having a locked state and an unlocked state for use with a catch is disclosed.

Electro-mechanical lock core with a cam member tailpiece

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

The present disclosure generally relates to a lock including a blocker (e.g., a bolt) useable to selectively prevent access through a portal such as a door. The blocker can be retained in a blocking position to prevent access through the portal by a retainer. In alternative embodiments, the blocker can also be retained in an open position to allow access through the portal. A retainer can be utilized to retain the blocker in the blocking position preventing access through the portal and can also be utilized, in certain embodiments, to retain the blocker in the open position to allow access through the portal. A retainer blocker can be utilized to maintain the retainer in position to retain the blocker (e.g., bolt) in a fixed position. An actuator may, in certain alternative embodiments, be employed to position the retainer blocker. In certain embodiments, the actuator is controlled by an electronic controller.

Electronic lock

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electro-mechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state. The interchangeable electro-mechanical lock core may include a core keeper moveably coupled to a lock core body. The core keeper may be positionable in a retain position wherein the core keeper extends beyond an envelope of lock core body to hold the lock core body in an opening of the lock device and a remove position wherein the core keeper is retracted relative to the envelope of the lock core body to permit removal.

A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second direction and assist the spring in closing the door.

Door closer system

An electro-mechanical lock for use with a lock device having a locked state and an unlocked state is disclosed. The electro-mechanical lock incorporates an actuation motor susceptible to lockdown and features a variety of lockdown mitigation structures and arrangements to combat the same.

Knob

A control module for a motorized door lock assembly includes a mounting bracket that is electrically connected to the door lock with wiping electrical terminals, and a housing with counterpart wiping electrical terminals that are electrically connected to a battery subassembly and an electric circuit. As a result, the battery subassembly and electric circuit can be quickly connected to the door lock merely by sliding the housing over the mounting bracket. Accordingly, the need for complicated and expensive connection systems is eliminated. Such an array of mutual wiping terminals also makes it possible to use the force of gravity to jettison the housing and its contents from the door lock in the event of a fire.
