The disclosure relates in general to a locking mechanism for a door. Specifically, the disclosure relates to a thumbturn latching mechanism having a triggered rotation-arresting assembly therein, configured to inhibit rotation of the lock mechanism upon unauthorized removal of the posterior portion of the latching mechanism, while still allowing for selectably bypassing the rotation-arresting mechanism from the anterior portion of the locking mechanism.

One or more embodiments describe a magnetic actuator including at least two magnets. One magnet is a semi hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the magnetic actuator. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet) to open or close a digital lock realised with the magnetic actuator. The magnetic actuator can also be used to realise a valve.

A swing bolt lock mechanism for preventing false status switch enabling is described. The lock mechanism is a swing bolt lock mechanism wherein the swing bolt has an inner ramp wall against which a blocker rod is spring-biased. A ramp extension arm is displaceably secured with the swing bolt and provides an extension of the ramp wall whereby the blocker rod may only be displaced when the swing bolt is at its fully locked position whereby to arrest the swing bolt at that position. The displacement of the blocker rod also toggles a lock status switch to provide an indication that the lock is at its locked position. Accordingly, the lock status switch cannot be prematurely actuated.

Pin tumbler locks are provided that include features for detecting tampering. Tampering may be detected in a number of different ways. As an example, abnormal movement of one or more of the driver pins in a pin tumbler lock can be an indication of tampering. In addition, one or more sensors can be included at the end of a keyway that detect picking or bumping beyond the length of normal key insertion. A mechanical actuator can be used for detection.

A lock apparatus generally includes a connecting portion, a housing, a primary lock, and a secondary lock. The connecting portion is engageable to the housing with a bolt assembly, and the primary lock locks the bolt assembly in the engaged position. The secondary lock arrests the bolt assembly in the engaged and locked condition in response to an attack that displaces the primary lock from a nominal configuration.

A system including a barrier implement, a barrier implement frame, wherein the barrier implement frame is configured to engage said barrier implement, a bolt lock, wherein the bolt lock is configured to secure the barrier implement frame to the barrier implement in a lock position, a central locking and/or release knob, a cable or rod, wherein the cable or rod is configured to interconnect the central locking and/or release knob and the bolt lock, and wherein the central locking and/or release knob is configured to release said bolt lock by pulling in the cable or rod to move the bolt lock out of the lock position.

The invention relates to a movement lock for a locking element or an actuator in a locking system which can be operated in a mechanical or mechatronic manner. Provision is made here for the movement lock to have a blocking element which can be brought into engagement with the locking element or actuator by a system which is maintained under tension or caused to move and can be triggered as a result of an external pulse application on the locking system.

A system including a barrier implement, a barrier implement frame, wherein the barrier implement frame is configured to engage said barrier implement, a bolt lock, wherein the bolt lock is configured to secure the barrier implement frame to the barrier implement in a lock position, a central locking and/or release knob, a cable or rod, wherein the cable or rod is configured to interconnect the central locking and/or release knob and the bolt lock, and wherein the central locking and/or release knob is configured to release said bolt lock by pulling in the cable or rod to move the bolt lock out of the lock position.

An automatic locking mechanism includes a heavy hammer, a baffle, a shifting piece, and a rotary shaft. The shifting piece is fixed on a locking rod of a lockset. The baffle is rotatably mounted on the rotary shaft. An impact component is arranged at one end of the baffle, and a stopper is arranged at the other end of the baffle. The stopper is located between the shifting piece and a lock body of the lockset. The stopper is rotatable into and out of the moving trajectory of the shifting piece. The heavy hammer is slidably arranged on a slide rod parallel to the lock body. The impact component is rotatable into and out of the moving trajectory of the heavy hammer.

An apparatus for preventing unwanted opening of a locked enclosure. The enclosure includes a lock, a door and a door bolt. The door is openable when the door bolt is retracted from a structure surrounding the enclosure. The apparatus includes a frangible guard plate, and an arm coupled to the guard plate by a spring. The arm is maintained in a first position under a bias of the spring. When the guard plate is fractured, the arm is free to move from the first position into a second position. The arm is positioned to engage the door bolt in the second position, thereby preventing retraction of the door bolt.
