A combination lock can be operated manually via the manipulation of rotatable dials and by way of a key, such as an electronic key. The lock includes one or more rotatable dials each having multiple indicia disposed thereon. Rotation of the rotatable dials to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a latched position and a second position in which the lock is in an unlatched position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.

An electronic deadbolt lock which includes a housing; an electronic recognition device disposed on the housing; a turnpiece pivotally mounted on the housing and connected to a deadbolt; a key operating mechanism disposed on the housing and connected to the deadbolt, wherein the deadbolt moves as a result of rotation of one of the turnpiece and the key operating mechanism; and a braking mechanism controlled by the electronic recognition device, wherein the braking mechanism normally applies a brake to the turnpiece to prevent the turnpiece from being rotated, and it is only when a user passes verification by the electronic recognition device that the turnpiece can be rotated by the user.

An electronic cabinet lock comprises a lock body base (101) and a handle (201), one end of the handle is movably connected with the lock body base, and the other end is attached with an unlocking mechanism and a engaging board (204), a self-holding electromagnet is attached on the lock body base, the self-holding electromagnet comprises an electromagnetic coil (301), a retractable body (302), a first permanent magnet (303), and a biasing structure body (304), when the electromagnetic coil (301) is energized forwardly, the retractable body (302) can be driven to perform a retracting operation, when the electromagnetic coil (301) is energized reversely, the retractable body (302) can be driven to perform an extending operation, a mutual snap-fit between the retractable body (302) and the engaging board (204) is realized and released by relative movement of the retractable body (302) and the engaging board (204) in the retractable direction and the permanent magnet (303) is mounted on an outer side of the hole for movement of the retractable body (302), in order to maintain the retracting state when the retractable body (302) retracts, the biasing structure body applies force to the retractable body (302), in order to maintain the extending state when the retractable body (302) extends. Also disclosed is a control method of the electronic cabinet lock for controlling the electronic cabinet lock.

An over-travel mechanism configured to couple an input shaft and an output shaft in an exit device assembly. The input shaft is connected to an actuator that linearly displaces the input shaft, and the output shaft is connected to a locking member of the exit device. The over-travel mechanism includes a link coupled to the output shaft, and a preloaded elastic member transmits force between the input shaft and the link. Movement of the input shaft from a first input shaft position to a second input shaft position causes the elastic member to urge the link from a first link position toward a second link position. Movement of the input shaft from the second input shaft position to a third input shaft position causes the elastic member to elastically deform without moving the link from the second link position.

The present disclosure provides an electro-mechanical lock assembly which illustratively includes a motor, a gear, a driver, a torque member, a housing, and a bezel. The motor is operable upon selective input. The motor is also coupled to the driver to engage both the gear and the housing when the motor is in operation. The bezel is attached to the gear such that when the driver is engaged with both the gear and the housing, manual rotation of the bezel will rotate the housing. The housing is attached to the torque member which is configured to move a latch such that when the bezel rotates the latch is moved.

A portable suitcase with an electronic combination locking device includes a suitcase body, a suitcase cover, a pair of lock hooks installed to the suitcase cover, a pair of first openings formed on the suitcase body for accommodating the lock hooks, a first locking device installed on an outer top surface of the suitcase cover, and a set of numeric keys and first buttons installed on the first locking device; a second locking device installed onto the suitcase body, a second button device installed onto the second locking device and disposed opposite to the first button, and a pair of latch mechanisms for receiving the actuation of the second button device, and the first locking device receives a correct unlock password to release the lock of the first button, and the second button device receives the actuation of the first button to detach the latch mechanism from the lock hook.

A locking mechanism includes a hasp having a tongue disposed along a first side of the hasp, and a captive latch pin protruding from the hasp disposed away from the tongue. The locking mechanism includes an actuator assembly with a captive latch and an actuator configured to manipulate the captive latch. The captive latch may receive the captive latch pin of the hasp. A body locking mechanism can obstruct access to at least a portion of the hasp and the actuator assembly, wherein the hasp may slidably move when the captive latch pin is not retained by the captive latch, and wherein a retention of the captive latch pin by the captive latch arrests the slidable movement of the hasp.

An electromechanical lock which is configured to provide a mechanical latch holdback feature, whereby a key is useable to retract a latch of the lock, the key can be removed, and the latch remains mechanically held back. The held back latch is remotely releasable. As such, a correctional officer can use his key to mechanically hold back the latch, such that the lock remains open. Subsequently, a control signal can be sent from a remote location causing the latch to be released and extended, such that the lock locks. This ability to remotely override the mechanical latch holdback is useful in a correctional facilityfor example, when the mechanical latch holdback has been engaged for cell doors and an emergency situation arises where a quick remote lockdown may be necessary, instead of having to perform the time-consuming task of re-locking the doors one-by-one, locally by key.

A triggering structure for an electronic lock includes a reed switch which is mounted on the lock body base and of which an ON-and-OFF state is acquired by an electronic lock control system, a permanent magnet for controlling the ON-and-OFF state of the reed switch, and a lever which passes through a handle and is mounted on the handle, ends of the lever each extending out of the surface and back face of the handle, the permanent magnet being attached to the end of the lever extending out of the back face of the handle. Also, an electronic lock and a triggering method thereof.

A combination lock can be operated manually via the manipulation of rotatable dials and by way of a key, such as an electronic key. The lock includes one or more rotatable dials each having multiple indicia disposed thereon. Rotation of the rotatable dials to predetermined indicia places the lock in the unlocked position. The lock can further include an electronic port and an actuator. Upon receipt of a predetermined credential via the port, the actuator can place the lock in in the unlocked position. The lock further includes a knob that, when the lock is in the unlocked position, can be rotated between a first position in which the lock is in a latched position and a second position in which the lock is in an unlatched position. The combination lock may automatically scramble the positions of the dials upon opening for security purposes.
