  • Patent number: 11328548
    Abstract: A system for sensing a position of a locking bolt of an industrial locking switch includes an inductive circuit, a converter, and a master controller. The inductive circuit includes an inductive coil and a capacitor electrically connected in parallel. The inductive coil is positioned to receive a locking bolt of an industrial locking switch when the locking bolt is transitioned to a lock position. The converter is configured to convert a frequency of a current signal on the inductive circuit to a digital frequency value. The master controller is configured to generate a bolt detection signal in response to determining that the digital frequency value changes by an amount equal to or substantially equal to a defined frequency shift corresponding to a frequency shift induced by the inductive coil in response to presence of the locking bolt within the inductive coil's magnetic field.

  • Patent number: 10789798
    Abstract: An industrial locking switch includes an inductive sensing circuit that uses a non-contact technique to detect when the switch's locking bolt has transitioned to the lock position. The inductive sensing circuit can comprise an inductive coil, a capacitor, and a converter that converts a frequency of a current signal through the inductive coil to a digital frequency value. A controller detects when the locking bolt has advanced to the lock position by monitoring the digital frequency value for frequency shifts indicative of a disturbance of the induction coil's magnetic field by the locking bolt. To validate operation of the inductive sensing system without requiring actuation of the locking bolt, a diagnostic switch connects a diagnostic capacitor to the inductive circuit to simulate the frequency shift caused by the locking bolt, and the inductive sensing system is validated if the expected frequency shift is detected.

  • Patent number: 9334676
    Abstract: An electrically controllable lock assembly (20) including a lock bolt (28), a first hub (36), a second hub (68), a first hub locker (64), a second hub locker (72), a first driver (62) and a second driver (70). The lock bolt (28) is movable between a latching position and an unlatching position. The first hub (36) is adapted to move the lock bolt (28) in response to movement of a first handle. The second hub (68) is adapted to move the lock bolt (28) in response to movement of a second handle. The first hub locker (64) is positionable to selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the first hub (36) from the first handle. The second hub locker (72) is positionable to selectively prevent or allow movement of the lock bolt (28) in response to torque being applied to the second hub (68) from the second handle.

  • Publication number: 20120304712
    Abstract: In a cylinder lock assembly, a latch operating tube has an enlarged end portion extending into an outer drive tube disposed in an outer handle. A locking spindle is disposed in the latch operating tube and has a locking tongue extending radially and outwardly through the outer drive tube to interlock with an outer rose when the locking spindle is pressed by a push button to move to a locked state. A locking plate is sleeved around the locking spindle and has a radial locking part to engage a protrusion that projects radially and inwardly from an inner surface of the enlarged end portion so that the locking spindle is locked against movements to an unlocked state when the locking spindle is in its locked state.

  • Publication number: 20090113957
    Abstract: A mortise lock for mounting in a door. The lock includes a bolt movable along a first axis between a first, extended position and a second, retracted position. The bolt has an end which, when the bolt is in its first, extended position and when the door is moved to a closed position, engages a strike which urges the bolt toward its second, retracted position. Also included are means for biasing the bolt to its first, extended position. The lock further includes a driven member which is mounted for rotation about a second axis. The second axis is generally perpendicular to the first axis. As the driven member is made to rotate about the second axis, it engages the bolt and urges it, overcoming the bias, to its second position. A drive member is mounted for rotation about a third axis, generally parallel to the second axis.
