Determining a position of a deadbolt used to lock and unlock a door is disclosed. An electromechanical lock can include a deadbolt that can retract or extend along a linear path as the door is to be locked and unlocked. A sensor such as an accelerometer can rotate along a non-linear path as the deadbolt moves along a linear path. The accelerometer can determine a gravity vector that can be indicative of a position of the accelerometer along the non-linear path. A controller can then determine a position of the deadbolt based on the gravity vector.

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.

A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion on the back plate defines part of a closed loop. A longitudinal locking bar is slidable along the back plate and has notches shaped to receive ends of the tags. Moving the locking bar between an unlocked position and a locked position operates the second hasp portion between an open position and a closed position. In the closed position, the first and second hasp portions complete and define the closed loop, where one or more tags can be installed in slots with the first end of the tag engaging a notch to lock closed the hasp portion.

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 lockable latching device includes a body defining a cavity and a plunger disposed within a cavity defined in the body. The plunger is translatable with respect to the body between an open position and a closed position. The lockable latching device also includes an annular rotator configured for rotating the plunger about a central longitudinal axis, and an annular latch transitionable between an unlocked state and a locked state. The lockable latching device further includes first and second elements. The lockable latching device also includes a force transmission mechanism operably connected to the first element, the second element, and the annular latch, with the force transmission mechanism configured to transition the annular latch from the unlocked state to the locked state in response to a first activation signal, and to transition the annular latch from the locked state to the unlocked state in response to a second activation signal.

A tamper-resistant lock assembly comprising a plate having a slot for receiving a key, the slot extending through the plate from an opening in a front face thereof to an exit in an opposing rear face thereof, the opening having a first profile and the exit having a second, different profile, the key comprising a shaft having a bit extending therefrom, the bit being formed of a shape memory material and being pre-configured such that its cross-sectional shape in its temporary form matches the first profile and the bit can be inserted through the slot via the opening and, upon application of a predetermined external stimulus, returns to a permanent form in which its cross-sectional shape matches the second profile and the bit can be retracted from the slot via the exit.

A merchandise security device is provided. The merchandise security device may include a lock mechanism operably engaged with a shape memory material configured to receive electrical power for locking and unlocking the lock mechanism. The shape memory material may be configured to change in shape in response to receiving electrical power to thereby lock or unlock the lock mechanism.

An in-vehicle locking safe system comprising a lockbox having one or more walls defining an enclosure, wherein the lockbox is configured with one or more apertures in one or more lockbox walls. The in-vehicle locking safe system further comprises a vehicle structural element including one or more studs configured to be inserted within one or more apertures in one or more lockbox walls, and a fastener component coupled to a portion of the one or more studs at a location inside the enclosure of the lockbox. In some embodiments, the vehicle structural element includes one or more of a vehicle chassis, a slider rail, a slider track, and/or a floor layer.
