A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.

The present disclosure provides an intelligent lock. In an embodiment, the intelligent lock includes: a lock body having a lock hole; a lock lever, the lock lever being capable of being plugged into and being unplugged out of the lock hole of the lock body; a first restricting member movably provided inside the lock body, and capable of being moved and latched into the lock hole to restrict the plugging of the lock lever into the lock hole or the unplugging of the lock lever out of the lock hole; a second restricting member movably provided inside the lock body, and capable of being abutted against the first restricting member so as to restrict a movement of the first restricting member; a detecting device provided in the lock body, and configured to detect the plugging operation of the lock lever into the lock hole or the unplugging operation of the lock lever out of the lock hole and to send a detection signal; and a main control element communicatively connected to the detecting device, and configured to determine a locking state of the intelligent lock in accordance with the detection signal sent by the detecting device.

A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

An exemplary latchbolt assembly includes a latchbolt, a locking sleeve, and a roller engaged between the latchbolt and the locking sleeve. The latchbolt is configured to drive the roller from a first position to a second position as the latchbolt moves from a projected position to a depressed position. The locking sleeve includes a blocking surface and a recessed portion. When the blocking surface is aligned with the roller, the locking sleeve retains the roller in the first position, thereby retaining the latchbolt in the projected position. When the recessed portion is aligned with the roller, the locking sleeve permits movement of the roller from the first position to the second position, thereby enabling depression of the latchbolt.

A method for operating a lock. A wireless command is received from a trusted device in a proximity range of the lock to enable a proximity mode. The proximity range is selectable by a user of the trusted device via an application. The proximity mode is enabled, and while enabled, a command is received to activate or deactivate the lock. The lock is activated or deactivated in response to the received activating or deactivating command.

A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

A wireless ultra-low power portable lock may be realized as a lock apparatus including: a locking mechanism having at least locked and unlocked states, the locking mechanism operable to provide physical resistance to being unlocked when in the locked state; an actuator operable to move the locking mechanism from the locked state to the unlocked state in response to a received signal; and a controlling unit configured to control the actuator and to receive one or more signals from one or more devices external to the lock apparatus.

A bumping preventing arrangement (10) for a lock device (38, 52, 68), the bumping preventing arrangement (10) comprising transfer member (12, 46, 64, 74) having a magnet (14), the transfer member (12, 46, 64, 74) being movable along an actuation axis (18) between a locked position (16) and an unlocked position (36); a plurality of electric conductors (20), each electric conductor (20) enclosing the actuation axis (18); and a plurality of switches (22), each switch (22) being associated with a respective electric conductor (20), and being arranged to selectively close an electric circuit comprising the associated electric conductor (20) such that eddy currents are induced in the electric conductors (20) when the magnet (14) moves along the actuation axis (18) from the locked position (16) towards the unlocked position (36). A lock device (38, 52, 68) and a method of controlling a lock device (38, 52, 68) are also provided.

The present disclosure generally relates to providing electronic locking systems. Using novel designs and network technology, the present systems, methods, and apparatuses can provide a secure alternative to a cam lock or a lock box for storing items that may be left unattended, without the use of a physical key. For example, in certain embodiments, the present systems, methods, and apparatuses can facilitate the locking and unlocking of a cam lock or a lock box by using a digital construct, an encryption system, and various native and/or third-party software components.

A safety switch includes a movably mounted locking bolt configured to lock an actuator in a defined locking position relative to the safety switch. The safety switch includes a movably mounted locking bulkhead movable between a first position and a second position. The locking bulkhead is configured to fix the movably mounted locking bolt in the second position via a positive fit.
