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 pressure relief door assembly includes a pressure relief door, a pressure-actuated latch, and a temperature-actuated lock. The latch is disposable in each of a latched configuration (to retain the pressure relief door in a closed position) and an unlatched configuration (to allow the pressure relief door to move into an open position). The lock is disposable in each of an unlocked configuration (to allow the pressure relief door to move into the open position when the latch is in its unlatched configuration) and a locked configuration (e.g., to lock the latch in its latched configuration, to lock the pressure relief door in its closed position, or both). The lock may include a bimetallic coil, that when exposed to a temperature that satisfies a temperature threshold, expands a sufficient amount to engage a locking pin with a corresponding portion of the latch to retain the latch in its latched configuration.

An electrical mechanical locking device. A lock has an outer shell with an indentation. An inner body is rotatably housed within the outer shell. A contact pin is connected to the inner body. A printed circuit board frame is rigidly connected to the inner body. A printed circuit board is attached to the printed circuit board frame. A driver arm support bracket is rigidly connected to the printed circuit board frame. A lock microprocessor is connected to the printed circuit board and electrically connected to the contact pin. The lock microprocessor is connected to a key identification code verification database. An electrical actuator is electrically connected to the lock microprocessor. A driver arm is pivotally connected to the driver arm support bracket. The electrical actuator is connected to the driver arm. A jam plate is connected to the driver arm. A jam plate return spring is connected to the jam plate and the printed circuit board frame. A locking pin is covered by the jam plate and inserted into the outer shell indentation when the electrical mechanical device is locked. When the electrical mechanical device is unlocked the locking pin is not covered by the jam plate and rises clear of the indentation. A powered key includes a key microprocessor. A battery power source is electrically connected to the key microprocessor. The key microprocessor has access to key database that includes a programmable key identification code for identifying the key. The key also includes a contact tip for insertion into the lock and for making electrical contact with the lock contact pin. In a preferred embodiment the electrical actuator is a nitinol wire.

An antitheft device attachable to an article, formed by two parts, one part comprises a means for remote interaction with a terminal detecting passage of the device, a hinge to allow movement between a protection position, and a release position, one of the parts having, at the end opposite to the movable hinge, a needle able to move in a direction perpendicular to the mid-plane of the device, the other part comprising a housing for receiving the needle, the housing comprising lock configured to allow the release of the needle with an opener, wherein the first part has three retractable cages enabling the needle to move between a retracted position where the tip of the needle does not project beyond the internal surface of the first part, and a deployed position in which the needle is engaged in the complementary housing when the device is in the closed position.

The invention relates to a lock (1) which can be actively released and locked by control technology, particularly for use in automatic storage machines having a plurality of compartments with compartment doors (2) which are to be opened individually, and to an automatic storage machine having at least one such lock (1). The lock (1) comprises a detent pawl (14), which can lock a locking element (9), which is permanently connected to a compartment door (2), in the lock such that the compartment door (2) can be held in closed position. The lock further has a first electric drive element (17) which transitions the detent pawl (14) from the locking position to a release position upon the applying of electrical power, such that the compartment door (2) can be opened. The lock (1) further comprises a security device (32), which prevents an automatic reset of the detent pawl (14) from the release position to the locking position when the lock (1) is in an unpowered state or the automatic storage machine is in an unpowered state, and an unintentional, accidental or improper locking of a compartment door can thus be avoided. In order to properly lock a compartment door, the security device (32) of the lock (1) comprises a second electric drive element, by means of which the detent pawl (14) can be transitioned back to the locking position thereof upon the applying of electrical power to said second electric drive element during closing of the compartment door (2).

A locking device employs improved lock management techniques based on time delay polices that use a random period of time. The locking device receives a first credential of a custodian, validates the first credential and determines a random period of time based upon a time-delay policy when the first credential is validated. The locking device executes a lock release protocol upon expiration of the random period of time.

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 has a first loop portion and a second hasp portion has a second loop portion. The first and second hasp portions are rotatable with respect to one another such that moving the lockout system has both an unlocked position and a locked position associated with an open position and a closed position. In the closed position, the first and second hasp portions complete and define a closed loop, where one or more tags can be installed in slots preventing further movement from the closed position.
