Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.

Certain aspects of the technology disclosed herein include an apparatus and method for electrically and mechanically connecting a deadbolt to a main housing of a lock. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door while receiving electrical energy from an energy storage device disposed in the deadbolt. The energy storage device disposed in the deadbolt can be proximate to one or more electrical contacts electrically connected to one or more components in the main housing via conductive components of a bolt carriage. The bolt carriage includes a groove attachable to a male detent connector attached to the deadbolt. The groove in the bolt carriage provides a mechanical connection to the deadbolt and also aligns pogo pins with electrical components of the bolt carriage to enable electrical transmission from the deadbolt to the main housing.

Disclosed are embodiments of a tapered bolt receiver for a door lock to accommodate misalignment, between a deadbolt mounted to a door, and an opposing jamb. The tapered bolt receiver can be configured to accommodate misalignment for a deadbolt having a non-tapered bolt, such as for an electromechanical smart lock having a battery stored within a battery compartment that is integrated with an enhanced bolt. Also disclosed are embodiments of a deadbolt plate pivot assembly that is pivotably mountable to a corresponding deadbolt assembly to define a plate pivot system, to accommodate a beveled door edge. An illustrative embodiment of the deadbolt plate pivot assembly includes opposing plate that captures a hinge assembly, which can include plastic plate hinges, which serve to locate the deadbolt plate pivot assembly with respect to a corresponding bolt housing, and can provide a spring force and/or constant torque when mounted to a beveled door.

A lock comprises a male element, and a female element for receiving the male element enabling aligned copular engagement. The male element has a shoulder and the female element a catch for closing behind the shoulder to hold the male element therein. The catch and a lock casing are held in the female element with the axis of the lock casing inclined, normally at a right angle, to the line of engagement of the male and female elements. The lock casing and the female element have juxtaposed faces inclined to the line of engagement of the male and female elements. At least one face on the lock casing extends from the casing outwardly from the line of engagement contiguous with an inwardly facing complementary face on the female element. In this way longitudinal forces generated by attempted separation of the engaged male and female elements are resolved by the faces into a lateral force on the female element.

A theft deterrent system for an electronics cabinet includes a handle cover having through-holes dimensioned to align with a through-hole in a handle of the electronics cabinet. The through-holes of the handle cover may be dimensioned to receive a shackle of a lock. The theft deterrent system further includes a shackle cover dimensioned to receive the shackle of the lock. The shackle cover may include an upper tab and a lower tab, each comprising a respective shackle slot therein dimensioned to receive the shackle of the lock.

An optical shield for keypad locks that has a frame provided with one or several structures into which standard structures (C1) fit that the lock keypads (C) have; one or several side panels that project from the frame body impeding the lateral view of the keypad of the lock (C) from an area near the user who is operating it; and means to fasten indirectly the frame to the lock module/keypad (C), without interfering in it. It can also have an additional panel, mounted on the frame and capable of sliding linearly in it, and provided with a window through which one can access a restricted area of the keypad, impeding the frontal view of the rest.

A magnetic lock which requires only a single magnet for operation, yet which is biased into a locking position. A latch is slideably mounted in a slide way defined by a housing with a latch opening at one end. The latch comprises a magnet at its base, and a latch positioner of ferromagnetic material is positioned within the housing alongside the latch. The positioner is longer than the magnet, such that the magnetic field biases the magnet to locate at the center of the length of the latch positioner. The latch itself is sufficiently long that it projects beyond the latch opening of the housing when the magnet is allowed to center. The slide way is open below the magnet a sufficient distance that when a key of a ferromagnetic, or optionally magnetic, material, is located near the base of the housing, the magnet and its associated latch are drawn further into the housing a sufficient distance that the latch is drawn out of the way of an associated catch.

A lock capable of locking a movable door includes a lock shell having opening parts, and hook tongues extending out of the opening parts. The lock further includes lock tongue support frames, lock tongue reset springs, left and right first guide grooves, and shifting blocks. The lock tongue support frames are movably disposed on the lock shell and combined with shaft pins. The hook tongues have lower shaft holes and rotatably sleeve the shaft pins via the lower shaft holes. Each lock tongue reset springs has one free end combined with the lock tongue support frames, and another one free end combined with the hook tongues. The left and right first guide grooves are symmetrically-arranged and correspond to the shaft pins. Two ends of the shaft pins respectively extending into the left and right first guide grooves. The shaft pins drive the hook tongues to move to be unhooked or locked when the lock tongue support frames move to drive the shaft pins to move along the left and right first guide grooves. Axial centers of the shifting blocks have center holes that allow shifting sheets to be inserted therein. The lock tongue support frames are able to move back and forth to respond to rotation of shifting handles on the shifting blocks when the shifting blocks rotate.

Certain aspects of the technology disclosed herein include an apparatus and method for electrically and mechanically connecting a deadbolt to a main housing of a lock. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door while receiving electrical energy from an energy storage device disposed in the deadbolt. The energy storage device disposed in the deadbolt can be proximate to one or more electrical contacts electrically connected to one or more components in the main housing via conductive components of a bolt carriage. The bolt carriage includes a groove attachable to a male detent connector attached to the deadbolt. The groove in the bolt carriage provides a mechanical connection to the deadbolt and also aligns pogo pins with electrical components of the bolt carriage to enable electrical transmission from the deadbolt to the main housing.

An exemplary strike box is configured for use with a lockset including a bolt operable to move in an extending direction and a retracting direction. The strike box includes a housing having an opening sized and configured to receive the bolt, and further includes a bolt-slowing mechanism mounted in the housing. The bolt-slowing mechanism is configured to engage the bolt as the bolt moves in the extending direction, and to exert a force urging the bolt in the retracting direction. The force exerted by the bolt-slowing mechanism slows the extension speed of the bolt, such that the strike box reduces noise generated during such extension.
