An intelligent lock, overlock, and lock system can be electrically controlled to open and close one or more locks. The lock, lock system, and method may function on a frequency selected to avoid cross talk, which permits numerous locks to function simultaneously on the same central system with little interruption or delay. A lock may be used as an overlock for an existing lock or be a primary lock and may include a pivoting engagement structure that engages a locking mechanism to provide added strength.

The present disclosure relates to an oven including a main body including a cooking chamber, a door rotatably coupled to the main body to open and close the cooking chamber, and a door locking device to lock the door not to be open with respect to the main body, wherein the door locking device includes a cam to be rotatable and including a plurality of first contact parts and a plurality of second contact parts, a lock releasing guide to linearly move to selectively come into contact with the plurality of first contact parts, and a locker to come into contact with the plurality of second contact parts and coupled to a locker holder provided in the door when coming into the plurality of second contact parts. Other various embodiments are possible.

This disclosure provides systems and methods for lockout-tagout procedures and systems supporting the same, including, without limitation, locking devices that can store and be locked simultaneously by multiple keyholders. In various embodiments, a single user can add multiple keyholders to a locking device. The user may not be able to remove anyone as a keyholder except himself or herself. Thus, the locking device may remain in a locked state until each of the added keyholders applies their digital key, password, PIN, and/or other personal identifying information to unlock the locking device by removing themselves as a keyholder.

A locking system for a door, including a primary locking mechanism and a secondary locking mechanism, in which the primary locking mechanism includes an electrical actuator that causes a first plate and a second plate to be magnetically attracted to one another when actuated such that rotation of a doorknob effects a corresponding rotation of the spindle, and in which the secondary locking mechanism includes a detent that is formed in a knob collar and an aperture that extends through a rotator collar; and a pin that is translatable through the aperture to be disposed in the detent of the knob collar, when the secondary locking mechanism is in an unlocked condition, such that the knob collar and the rotator collar are rotatably fixed to one another.

A compartment assembly includes a housing, a door movable relative to the housing between an open position and a closed position, an arm extending from the door having a first engagement surface and a second engagement surface, and an actuation system. The actuation system includes a prime mover and a pin connected to the housing and operably coupled to the door. The pin is movable by the prime mover. A biasing mechanism is coupled to the pin to bias the pin into engagement with the arm. When the door is in the closed position, engagement between the first engagement surface and the pin restricts movement of the door. Engagement between the second engagement surface and the pin opposes the biasing force of the biasing mechanism to allow movement of the door.

An equipment assembly is disclosed that includes a first equipment housing having a first penetration, a latch assembly disposed within the first equipment housing, a second equipment housing having a second penetration and a security bezel configured to cause the latch assembly to rotate through the first penetration and the second penetration.

Locking systems and devices and methods for using the systems and devices are provided. A locking system may include a receptacle having a lock and an electronic credential. If the electronic credential is brought into proximity of the receptacle, then a key can be used to open the lock. The electronic credential can be incorporated into a vehicle or into a handheld device.

A wireless ultra-low power portable lock may be realized as a lock apparatus including: a locking mechanism having at least locked and unlocked states, the locking mechanism operable to provide physical resistance to being unlocked when in the locked state; an actuator operable to move the locking mechanism from the locked state to the unlocked state in response to a received signal; and a controlling unit configured to control the actuator and to receive one or more signals from one or more devices external to the lock apparatus.

An exemplary exit device system includes a pushbar assembly and a control system. The pushbar assembly includes a latch having an extended position and a retracted position, a blocking member having a blocking position in which the blocking member retains the latch in the extended position and an unblocking position in which the blocking member permits the latch to move to the retracted position, a pushbar operable to move the blocking member between the blocking position and the unblocking position, and an electronic driver operable to move the blocking member between the blocking position and the unblocking position. The control system is configured to operate the electronic driver to electrically move the blocking member between the blocking position and the unblocking position based upon information received from a credential reader.

Systems and methods for wireless unlocking of lock systems on enclosures within a vehicle are provided. A lock system may be unlocked via a digital key communicated to the lock system via any suitable communication protocol, for example, a short range communication protocol. The digital key can be embedded or otherwise stored and accessed in an application accessible via a user interface device.
