A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.

A dead bolt lock system including a slider member operatively coupled to a dead bolt such that when the slider member is in a first position, the dead bolt is in an extended position. When the slider member is in a second position, the dead bolt is in the retracted position. The system also includes a first movable member positioned in a path of movement of the slider member and configured to be displaced by the slider member to allow the slider member to move to the second position. The system includes a first lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member, a second lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member.

A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

Adoor latch includes a gripper adjustable between a gripping state and a release state, which gripper, in the gripping state, is able to grip a closing member for holding the door closed which moves relatively closer to the gripper in a closing direction as a door of the domestic appliance is closed, and, in the release state, frees the closing member for opening the door, wherein, when the door is closed, the gripping state of the gripper is released by a relative releasing movement of the closing member carried out in the closing direction; and an electrically controllable displacement mechanism for displacing the gripper, under electrical control, from a retracted position into an advanced position against a restoring spring force, which advanced position, when the closing member is gripped, corresponds to a state in which the door is closed to a lesser degree than in the retracted position.

A locking mechanism for a door panel to be positioned within and out of blocking relationship with an opening. Mechanism includes a deadbolt rotatably connected to the wall and having a curved configuration and a locking bracket connected to the door panel. The locking bracket extends from the door panel in an angular direction with respect to a plane of door panel. With door panel in a closed position and deadbolt in a first position, the locking bracket extends through the curved configuration. Deadbolt is in blocking relationship with the locking bracket in a direction along a plane of the door panel and is not in blocking relationship in a direction along the locking bracket. With door panel in closed position, deadbolt is in a second position not in blocking relationship with the locking bracket permitting door panel to move in a direction along a plane of the door panel.

A vertical door latch assembly includes an electro-mechanical lock assembly and a rotatable engagement feature. A controller is in electrical communication with the electro-mechanical lock assembly. The controller is configured to direct the electro-mechanical lock assembly between a locking position with the electro-mechanical lock assembly in locking engagement with the rotatable engagement feature and a non-locking position with the electro-mechanical lock assembly in non-engagement with the rotatable engagement feature.

A lock system for an enclosure comprises a locking mechanism selectively disposed in a locked or unlocked position. A first blocking pin prevents the locking mechanism from being moved to the unlocked position when disposed in a first blocking position via a first biasing mechanism. A solenoid mechanism imposes a force on the first blocking pin when in an energized state so that the first blocking pin is placed in an unblocking position. A second magnetizable blocking pin remains in contact with the first blocking pin when the solenoid mechanism is in an unenergized state. A second biasing mechanism biases the second blocking pin toward an unblocking position. During normal operation, the secondary biasing mechanism maintains the second blocking pin in its unblocking position so that the second blocking pin is separated from the first blocking pin when the solenoid mechanism is in the energized state.

The present invention discloses a lock system, comprising a lock assembly that includes a hasp and an interlock mechanism detachably engaging with the hasp. Further included is a latch system that latches the interlock mechanism in a lock position.

The lock of the present invention includes a housing, a fastening element, a stopping element, a first locking mechanism and a second locking mechanism. The fastening element is movable relative to the housing and is selectively located at a securing position and a releasing position; the stopping element has a first state and a second state. The stopping element in the first state restricts the fastening element to be in the securing position while the stopping element in the second state releases the fastening element. The first locking mechanism includes a dynamic element and a sensing device. The dynamic element drives the stopping element to change between the first state and the second state. The sensing device senses a signal and controls the dynamic element.
