An exemplary lockset includes a mortise case, a magnet assembly mounted in the mortise case, and a manual actuator operable to move the magnet assembly between a coupling position in which a first magnet of the magnet assembly is aligned with a reference point and a decoupling position in which the first magnet is misaligned with the reference point. In certain embodiments, the magnet assembly further includes a second magnet having an opposite polarity as the first magnet, and the second magnet is misaligned with the reference point when the magnet assembly is in the coupling position and is aligned with the reference point when the magnet assembly is in the decoupling position.

A manually operated locking bolt (1) having a cylindrical, sleeve-shaped bolt guide (3) and a bolt (2), which is mounted to be axially displaced in the bolt guide (3), and which has a locking end (15) and an actuating end (31), wherein the bolt (2) is mounted to be axially displaced between a first axial end position or a second axial end position within the bolt guide (3) and can be locked, wherein at least one sensor (27) is fastened to the bolt guide (3), which sensor detects the two axial end positions of the bolt (2) as a measured variable and generates therefrom a further processable electrical signal.

A double-door lock assembly includes a first lock and a second lock which are mounted to a first door and a second door, respectively. The first lock includes a first rotary member, a first magnetic member and a linkage member. The second lock includes a second rotary member having a driving portion and a second magnetic member, The first and second rotary members can be driven to rotate together to open or close the first and second doors simultaneously when the first and second magnetic members are attracted to each other and the driving portion on the second rotary member contacts against the linkage member on the first rotary member.

The present disclosure is directed to a lever apparatus having a lever connected to a latch assembly operable to open the latch when rotated to a second position from a first position under an actuation torque. The apparatus further includes a magnet assembly with first and second magnets operably coupled to the lever apparatus. The magnet assembly is operable to generate a return torque in an opposite direction to that of the actuation torque such that the lever is returned to the first position after the actuation torque is removed from the lever.

An elevator call box with internal, concealable latching mechanism comprises an internally disposed, cylindrical magnetic pin with a relatively low pull force that is slidably displaceable by an larger, external magnetic force supplied by a service technician. When the access door is closed, magnetic pin penetrates an orifice in a locking tab to lock the call box. The pin magnet is normally attracted to an adjacent, magnetically attractive clip snap-fitted to a latching block. The latch is externally disengaged via a stronger portable magnet carried by service personnel. The larger magnetic pull force of the portable magnet slidably displaces the smaller magnetic latch pin, freeing the locking tab to permit pivotal opening of the access door. Once the stronger magnet is moved away, the smaller magnetic pin, which is attracted magnetically to the clip, will return to it's rest position penetrating the locking tab and locking the control.

A vehicle door handle to control the opening of a vehicle door includes a door latch mechanism to release the vehicle door when actuated and a handling element mobile with respect to a handle frame between a rest position and an actuation position in which it actuates the door latch mechanism. The vehicle door handle also includes at least one static magnetic element fixed in motion with the handle frame and at least one mobile magnetic element solidary in motion with the handling element, generating a haptic feedback by defining stable or unstable positions of the handling element in which the static and mobile magnetic element face and attract or repel each other.

Some embodiments include a lock cylinder comprising: a plug assembly having a front portion and a back portion; a housing shell within which the plug assembly is rotatably disposed, wherein the housing shell includes a notch; wherein the back portion of the plug assembly comprises: a locking pin that is movably disposed, and wherein the locking pin is configured to prevent a rotation of the plug assembly when the locking pin is engaged in the notch and prevented from retracting by a multi-stable mechanism; and the multi-stable mechanism having at least two stable configurations corresponding to respectively to a locked state and an unlocked state, wherein the multi-stable mechanism can maintain the stable configurations without consuming energy; wherein, at a first stable configuration, the multi-stable mechanism prevents the locking pin from retracting, and, at a second stable configuration, the multi-stable mechanism enables the locking pin to retract.

A lever apparatus having a lever connected to a latch assembly is operable to open the latch when rotated to a second position from a first position under an actuation torque. The apparatus further includes a magnet assembly with first and second magnets operably coupled to the lever apparatus. The magnet assembly is operable to generate a return torque in an opposite direction to that of the actuation torque such that the lever is returned to the first position after the actuation torque is removed from the lever.

A passive continuity monitoring device is disclosed. This device can be used to protect a lock or other locking device and to indicate when a breach of the lock has occurred. The lock can include a connector with a magnet at one end spaced from an other magnet. The connector can be held in tension when the lock is engaged to maintain the spacing between the magnets. A breach in the loop of the system will cause the magnets to touch and complete a circuit. The completion of the circuit can trigger an alarm, can take a picture of the surrounding area, and can transmit a signal to interested parties.
