Abstract: An auxiliary lock includes an inside housing mounted to a lock cylinder and a first flange extends axially from one of two ends of the inside housing. A mounting plate is mounted to the lock cylinder and contacts the inside housing. The mounting plate includes a second flange which is mounted to outside of the first flange of the inside housing. The lock cylinder is protected and reinforced in the radial direction by the overlapped first and second flanges. When the inside housing is hit, the inside housing does not expand outward to be pried up. The reinforcement structure is made by way of pressing to use less material and to reduce the manufacturing cost.

Abstract: Disclosed herein is a movable bolt pan in which the bolt pan frame is secured directly to a safe door. The positions of securement of the bolt pan frame to the safe door are spread across a large percentage of the door slab. An entirety of the leading edge of the movable bolt pan contacts the door jamb of the safe when the movable bolt pan is in the closed position. A handle on an exterior of the safe door can be used to slide the movable bolt pan laterally from the closed position to the open position, allowing the safe to be opened.

Abstract: The present utility model discloses a safety lock device including a first lock body and a second lock body. The first lock body is provided with a movable member, a first action member and a second action member. The second action member and the first action member are operated sequentially to enable the movable member to act to unlock. The first action member or the second action member is operated individually that cannot achieve the unlocking. The unlocking of the safety lock device is completed only by fitting the two moving members with each other, thereby solving the problems of the easy unlocking by children and the potential safety hazards.

Abstract: An electronic lockbox uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key.

Abstract: A lock can include attack-resistant and/or weather-resistant features. Attack-resistant features can include a sacrificial link between a locking mechanism and an external keyway covering an exterior face of the locking mechanism. The sacrificial link can break during a torque attack on the lock such that the full force of the torque attack is not applied to the locking mechanism. Weather-resistant features can include drain openings in one or more housing components external to the locking mechanism to facilitate drainage of liquid matter from the lock before the liquid matter reaches the locking mechanism.

Abstract: The present disclosure provides systems for smart security. The system may include a smart security device, a control module, a driving module, and a mechanical structure. The control module may be configured to send a control instruction to the driving module. The driving module may be configured to drive the mechanical structure based on the control instruction, thereby performing a state switching operation of the smart security device.

Abstract: A hoop lock including a shackle, a crossbar, and a locking assembly operable to secure the shackle to the crossbar. The shackle may include a straight foot and a bent foot, and the locking assembly may engage the straight foot and the bent foot to secure the shackle to the crossbar.

Abstract: A clamp lock includes a body, a lock mechanism coupled to the body, and a clamping member supported by the body and operatively coupled to the lock mechanism. The clamping member and body cooperatively define a slot. The clamping member is movable relative to the body by actuating the lock mechanism from a first position, in which the clamping member is configured to engage the part of the portable electronic device, to a second position, in which the clamping member is configured to disengage the portable electronic device. The clamp lock includes a spring configured to bias the clamping member toward the second position. The slot includes an opening at an outer periphery of the body and an inner channel located inward of the opening. The opening has a first height and the inner channel has a second height that is larger than the first height.

Abstract: A deadbolt lock status sensing assembly for monitoring status of a deadbolt member of a deadbolt assembly on a door may include a sensible element mountable on one of the door and the deadbolt assembly, and a sensing element mountable on one of the door and the deadbolt assembly. The sensing element and the sensing element may be configured to move with respect to each other when the deadbolt member of the deadbolt assembly moves between an extended condition and a retracted condition of the deadbolt.

Abstract: A deadbolt assembly with a latch assembly and a lock cylinder. The deadbolt assembly includes a first torque blade longitudinally extending along a first axis and a second torque blade longitudinally extending along a second axis. The second torque blade is operatively coupled with the latch assembly to actuate the bolt between the retracted position and the extended position. The deadbolt assembly includes a geared arrangement operatively coupling the first torque blade and the second torque blade. The gear arrangement is configured to apply rotational movement of the first torque blade to the second torque blade.

Abstract: An exemplary clutch mechanism includes a casing, first and second hubs rotatably mounted to the casing, an electrically-actuated drive assembly mounted within the casing, and a clutching lug movably mounted within the casing. The lug has an engaged position in which the lug couples the hubs for joint rotation and a disengaged position in which the hubs are rotationally decoupled. The drive assembly is operable to drive the lug between the engaged and disengaged positions to couple and decouple the hubs. The clutch mechanism is modular and self-contained within the casing such that the mechanism can be installed to each of a plurality of different lockset products without opening the casing.
