Abstract
A lock arrangement including an electrically powered lock actuator, a power receiver (30) and a power transmitter (18). The electrically powered lock actuator is adapted for mounting in or on a door (10). The power receiver (30) is adapted for mounting in or on the door (10) in electrical connection with the lock actuator. The power transmitter (18) is adapted for mounting adjacent the door (10) and for transmitting power across an air gap to the power receiver (30).
Claims26
A lock arrangement including:
- an electrically powered lock actuator adapted for mounting in or on a door;
- a power receiver including a first core with a first wire coil formed thereon, the power receiver adapted for mounting in or on the door in electrical connection with the lock actuator;
- and
- a power transmitter including a second core with a second wire coil formed thereon, the power transmitter adapted for mounting adjacent the door and for transmitting power across an air gap to the power receiver,
- wherein the magnetic axes of the first and second cores are substantially parallel, and spaced apart, when the door is closed, wherein the first and second cores generate first and second magnetic fields respectively and the first and second magnetic fields overlap longitudinally in a direction normal to the magnetic axes of the first and second cores.
A method of providing power to an electrically powered lock actuator mounted in or on a door, the method including the steps of:
- supplying power to a power transmitter mounted adjacent the door, the power transmitter including a first core with a first wire coil formed thereon;
- transmitting power from the power transmitter across an air gap to a power receiver mounted in or on the door, the power receiver including a second core with a second wire coil formed thereon, wherein respective longitudinal axis of the first and second cores are substantially parallel, and spaced apart, when the door is closed, wherein the first and second cores generate first and second magnetic fields respectively and the first and second magnetic fields overlap longitudinally in a direction normal to the magnetic axes of the first and second cores;
- and
- supplying power from the power receiver to the lock actuator.
