Abstract
A door lock mounted to a door includes a latch head. A receiver includes a charging circuit and is mounted to the door. A battery provides electricity required for moving the latch head between a latching position and an unlatching position or providing electricity required for permitting or not permitting movement of the latch head from the latching position to the unlatching position. A transmitter includes a wireless transmitting circuit and is mounted to a door frame to which the door is pivotably mounted. The transmitter is connected to a power supply. When the door is in an open position, the receiver is not aligned with the transmitter. When the door is in a closed position, the receiver is aligned with the transmitter, the receiver receives a radio wave from the transmitter, converts the radio wave into electricity, and stores the electricity in the battery.
