Abstract: The unlocking mechanism of the present invention is actuated as a result of contact with the door's existing lever. When an occupant rotates the door's lever, it not only retracts the door's latch, but the handle will also engage the unlocking mechanism of the present invention, the door lever engaging the unlocking mechanism. The door's lever follows the geometry of the cam thereby pushing the sliding bar of the unlocking mechanism thereby engaging a latch release. The latch release moves the locked lever of the door's deadbolt assembly and the deadbolt is retracted. When the door's lever is returned to its normal state, a spring pushes the sliding bar backward to the ready position. The latch release rotates to its ready position and the mechanism is ready for a subsequent activation.

Abstract: A locking mechanism includes a locking receptacle, a movable member, and a locking member. The locking receptacle has an opening with sloped walls leading into a slot configured to receive a connecting member. The connecting member includes sloped walls that converge along the direction of docking. The movable member is positioned in the locking receptacle and configured to rotate from an unlockable position to a lockable position to secure the connecting member. The locking member is configured to switch between a locked position and an unlocked position, and further configured to secure the movable member while the movable member is in the lockable position and while the locking member is in the locked position.

Abstract: Disclosed herein is a redundant boltwork mechanism comprises a master lock plate and a sublock plate slidably coupled to the master lock plate. A first lock is coupled to the mater lock plate and a second lock is coupled to the sublock plate. A cross slide with a plurality of bolts and at least one other slide are coupled to the safe door such that turning that handle of the safe door causes movement of the cross slide and at least one other slide from a first position to a second position, allowing the safe door to be opened. The safe door can be unlocked by unlocking either the first lock or the second lock, which causes the second lock tongue to retract from blocking the at least one slide.

Abstract: A security apparatus for a portable electronic device includes a force-transmission member having a length, a first end, and a second end. A lock head is coupled to the first end of the force-transmission member, the lock head configured to selectively engage the electronic device and movable by the force-transmission member between a locked position, in which the lock head is secured to the electronic device, and an unlocked position, in which the lock head is unsecured from the electronic device. An actuator assembly is spaced a distance from the lock head along the length of the force-transmission member. The actuator assembly includes a body and a manual actuator pivotally coupled to the body, the manual actuator being pivotable from a first position to a second position to move the movable member relative to the body such that the lock head moves from the unlocked position to the locked position.

Abstract: Disclosed are a control method for an electronic lock and an electronic lock based on the control method. The electronic lock has a simple structure, and jointly control a snap hole on the handle with a telescopic body of the electromagnet located on the lock body base and a push rod controlled by the unlock mechanism. The telescopic body of the electromagnet has the characteristics of self-holding function when power off through the first permanent magnet, which not only the hidden danger of illegal unlocking through mechanical structure is solved, but also the power consumption of electronic lock in preventing illegal lock opening can be greatly reduced. The market's technical requirements for electronic locks can be met, and high promotion value can be obtained.

Abstract: A cooler and freezer access control system locks a cooler or freezer when occurrence of an event is detected that requires limiting access to the inside of the cooler or freezer. Examples of such events include the loss of power to the cooler or freezer for a predetermined period of time, the opening of the cooler or freezer 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 or freezer door open while stocking the cooler or freezer with product.

Abstract: A lock is provided, including: a housing; a latch member, movably mounted to the housing and including a first blocking portion; a blocking member, movably mounted to the housing and including a second blocking portion; a locking member, operably mounted to the housing; wherein when the locking member is in a locking state and the latch member is in a first position, the locking member and the blocking member are free of blocking from each other so that the first blocking portion and the second blocking portion are blocked with each other, and the latch member is unmovable toward a second position; when the locking member is in a unlocked state, the second blocking portion and the first blocking portion are unblocked with each other and the latch member is movable to the second position so that the latch member is retractable from a locked object.

Abstract: A lock structure includes a lock housing defining an accommodating cavity and a lock head. An outer end surface of the lock housing defines a through hole communicated with the accommodating cavity. The lock head is movably arranged in the accommodating cavity. An outer end of the lock head is movably arranged in the through hole to stretch out of or retract into the through hole. Operating ports are defined on sides of the lock housing. The operating ports are communicated with the accommodating cavity. The lock head includes a movable piece and a lock tongue piece, the movable piece is arranged in the accommodating cavity. The lock tongue piece passes through the through hole and extends into the accommodating cavity. The lock tongue piece is detachably connected with the movable piece.

Abstract: A hoop lock including a shackle and a crossbar, with the shackle having a pair of legs extending from a body portion, and each of the legs having a foot including a tip with a non-circular cross-section. The cross-bar includes a housing having a pair of foot-receiving openings and a pair of tip-receiving openings substantially aligned with foot-receiving openings. The tip-receiving openings are configured to matingly engage the tips such that the tips are rotationally coupled to the housing.

Abstract: A system may include a lock assembly having secured and unsecured conditions and having an opening for receiving a lock actuating object. An access restriction element may be positionable with respect to the lock assembly to affect access to the opening of the lock assembly. The access restriction element may have at least two conditions, a blocking condition in which the access restriction element at least partially obstructs access to the opening of the lock assembly and an access condition in which the access restriction element is configured to permit access to the opening of the lock assembly. The system may also include an access detection assembly configured to detect attempted access to the opening of the lock assembly by sensing changing of the access restriction element from the blocking condition to the access condition.
