Systems and methods for providing secure locks having redundant access channels are disclosed. In some embodiments, the smart lock has a hardware processor, a power source, a cylinder, a button that forms a rose knob, and a rose protector. The rose knob and rose protector protect and conceal the hardware processor, the power source, and the cylinder. The rose protector forms an annular groove that slidabiy interlocks with the rose knob. The rose knob has a plurality of redundant access channels for receiving authentication information, The redundant access channels may include a biometric scanner for receiving biometric information, a passcode keypad for entering a token, or a wireless transceiver for receiving a token from a mobile device and transmitting a response to the mobile device. When the user cannot open the lock through the first redundant access channel, the smart lock is configured to allow access through a second access channel.

The invention relates to an improved locking device for the closure of doors on cabinets, of boxes or compartments, which offers high resistance to unauthorized attack and, in particular, can take up high torques. For this purpose, use is made of a coupling arrangement having a manually or electronically movable actuating member, a driver (40), which interacts with the actuating member, and a blocking member (50). The blocking member (50) has the form of a cylinder, the cylinder axis of which runs parallel to the rotor axis (19). The blocking member (50) in its blocking position engages in a depression (17) on the outer side of the rotor (10) or in a depression (22) on the inner side of the wall (21) of the stator (20) and is held in this blocking position by spring force.

An exemplary product line system includes a common platform and a plurality of component families, each of which includes a plurality of interchangeable component species configured for use with the common platform. The common platform includes an inside drive assembly and a chassis assembly including a chassis and an outside drive assembly. A lockset assembled from the system includes the common platform and a plurality of modular components. Each of the modular components corresponds to a respective one of the component families, and is provided as a selected species of the corresponding component family. The lockset has a function defined by the set of component species installed to the lockset. The function of the lockset can be changed by altering the set of component species installed to the lockset without disassembling the chassis assembly.

The manual release mechanism described herein enables a passenger to attempt to manually open the transit door, but delays opening until the vehicle is no longer moving. A motion transfer device (14) moves to an unlocking position of the door lock (10) only when the manual release mechanism is activated to store energy in a mechanical energy storage device (40), and an electromechanical device (26) is de-energized to release the motion transfer device (14).

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.

A driving mechanism for a door lock and a door lock are provided. The driving mechanism includes a motor, a planetary gear assembly, and a cage. The planetary gear assembly includes a ring gear, a planet gear, and a sun gear. The motor is rotatably connected to the ring gear. The planet gear is further rotatably connected to the sun gear. The planet gear is connected to the cage. When the sun gear is in a fixed state, the ring gear is driven by the motor to rotate. When the ring gear is in a fixed state, the sun gear, the planet gear, and the cage are configured to cooperate with one another, to make the planet gear rotates relative to the sun gear and the cage rotate.

An electronic lock includes a control circuit module and an electromagnetic mechanism. The electromagnetic mechanism is electrically connected to the control circuit module, and the electromagnetic mechanism includes a driving member and a magnet. The driving member is configured to be driven by the control circuit module to be located at one of a first position and a second position. When the driving member is not driven by the control circuit module, the driving member is configured to be held at one of the first position and the second position by the magnet.

The invention discloses an accidental unlocking prevention electronic lock, in particular an accidental unlocking prevention electronic lock in the field of electronic locks. The accidental unlocking prevention electronic lock of the invention comprises a lock cylinder, a control circuit and a clutch sleeve, wherein the control circuit and a key hole are installed in the lock cylinder, and further comprises a transmission system, a power shaft, a clutch cam, a key cam, a key pin and a suspension, wherein the lock cylinder is internally provided with a clamping jaw, a torsion spring and a clamping jaw motor; one end of the clamping jaw is connected with an output shaft of the clamping jaw motor, one end of the torsion spring is fixed in the suspension and the other end thereof is connected with the clamping jaw; the key cam is provided with a limiting groove and the lock cylinder is provided with a limiting pin. The invention has the advantages of high safety and reliability, low power consumption, small volume and strong impact-resistant performance, and can be protected from accidental unlocking even under the conditions of high-speed impact and severe vibration.

A locking device having a guard lock for safety doors includes a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart. The housing includes a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor. The actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable in a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing.
