A non-contact transmission device for an electronic lock includes a housing. The housing has an accommodation trough to accommodate a retainer in a slidable manner. The retainer is provided with an RFID coil. An inner side of the housing is formed with a positioning trough. When the retainer is slid in the accommodation trough, the RFID coil is positioned in the positioning trough, such that the RFID coil is closer to the outer edge of the housing without lowering the strength of the housing. When two non-contact transmission devices are mounted to a door frame and a door panel respectively, the distance between the RFID coils of the two non-contact transmission devices can be shortened to improve the transmission efficiency between the RFID coils.

A multipoint lock is described. The multipoint lock includes a main latch. The main latch has a latched position where the main latch is configured to extend a first distance from an unhinged edge of a door panel. The main latch is configured to be retractable toward the unhinged edge of the door panel by rotation of a latch drive hub in each of a clockwise direction and a counterclockwise direction relative to a first side of the door panel. The multipoint lock also includes at least one auxiliary latch and a deadbolt drive hub. Rotation of the deadbolt drive hub substantially simultaneously actuates the main latch and the at least one auxiliary latch.

A wireless transmission system used for a self-locking lock box has a first transmission unit received in a first insert hole of a door frame, and a self-locking lock box secured at a door plank. The self-locking lock box is provided therein with a square bolt able to eject out of the lock box, and the square bolt is connected with a control pin and has its front end fixed with a second transmission unit. By so designing, when a user closes the door plank, the control pin will be pressed by the door frame and release the square bolt to make the square bolt eject out of the self-locking lock box and get into the first insert hole of the door frame, thus enabling the first transmission unit to approach the second transmission unit for elevating transmission efficiency.

The main latch is configured to be retractable toward the unhinged edge of the door panel by rotation of a latch drive hub in each of a clockwise direction and a counterclockwise direction relative to a first side of the door panel. The multipoint lock also includes at least one auxiliary latch and a deadbolt drive hub. Rotation of the deadbolt drive hub substantially simultaneously actuates the main latch and the at least one auxiliary latch.

A multipoint lock for securing a door panel is described. The multipoint lock includes a first latch, a second latch, a first hub rotatable with at least one of a thumb-turn knob or a key, and a second hub rotatable with a handle lever. Upward rotation of the handle lever causes both rotation of the first hub and rotation of the second hub in the same rotational direction

Lock arrangement and method for transferring electrical power with a lock arrangement that includes a counterpart of the lock and an electrical lock including a lock case. A device for wirelessly sending electrical power to the lock case and/or into connection with the lock case is arranged in connection with the counterpart of the lock, and arranged in the lock case and/or in connection with the lock case are a device for wirelessly receiving electrical power from the device for sending electrical power that is arranged in connection with the counterpart of the lock. The counterpart of the lock wirelessly sends electrical power to the lock case and/or into connection with the lock case with the device that is for sending electrical power, and the lock case wirelessly receives electrical power from the counterpart of the lock with the device that is for receiving electrical power, when the lock and the counterpart of the lock are at a certain distance from each other. The electrical power received from the connection of the lock is measured and the power level of the electrical power sent is increased and/or decreased in such a way that the measured level of the electrical power received is between certain predetermined upper and lower values or essentially at a given preset level.

A multipoint lock is described. The multipoint lock includes a main latch. The main latch has a latched position where the main latch is configured to extend a first distance from an unhinged edge of a door panel. The main latch is configured to be retractable toward the unhinged edge of the door panel by rotation of a latch drive hub in each of a clockwise direction and a counterclockwise direction relative to a first side of the door panel. The multipoint lock also includes at least one auxiliary latch and a deadbolt drive hub. Rotation of the deadbolt drive hub substantially simultaneously actuates the main latch and the at least one auxiliary latch.

Example systems and methods are described that wirelessly charge a rechargeable battery associated with a lock. In one implementation, a rechargeable battery is electrically coupled to an electronic lock module associated with a door corresponding to a door frame. An electronic control module associated with the door frame and physically separate from the electronic lock module generates a wireless charging link between the electronic control module and the electronic lock module. The electronic control module transmits a charging signal to the electronic lock module via the wireless charging link, and the electronic lock module uses this charging signal to charge the rechargeable battery. The implementation also includes a lock associated with the door that can be locked or unlocked by the electronic lock module.

A door lock apparatus, comprising a male component; a connection to a power source; a lock actuator, powered by the power source and configured to move the male component at least partially through a strike and into a box beyond the strike in the path of the male component to lock a door, wherein the male component comprises a plurality of parallel subcomponents oriented lengthwise in the direction of a path of the male component; a bed of sensors positioned in the box and configured to sense a number of parallel subcomponents that contact the bed after the male component has been moved into the box; and an alarm in communication with the bed, wherein the alarm is triggered when an attempt is made to lock the door and an insufficient number of parallel subcomponents contacting the bed has been sensed by the bed of sensors.
