Embodiment Construction
[0017] figure 1 A schematic diagram of the solution of one embodiment of the invention is presented. In the solution according to the invention, the lock counterpart 101 , which is fitted into the door frame, periodically scans for the presence of the door lock 102 . The lock 102 and lock counterpart 101 comprise coils 103, 104 for wirelessly transferring electrical power. When the lock 102 is spaced a suitable distance from the lock counterpart 101 (eg, when the door is closed), the lock counterpart 101 controls the current to the transmitter coil 103, which generates a magnetic field. The magnetic field is connected to the receiver (ie to the lock's coil 104) and there a rectified and filtered alternating current is formed. Thus, the power transfer is based on a magnetic induction corresponding to the magnetic induction in the power transformer (primary and secondary). In the solution according to the invention, for example, two planar coils are used instead of an iron-c...

Lock arrangement and method for transferring electrical power with a lock arrangement that comprises a counterpart (101, 301) of the lock and an electrical lock (102, 202) comprising a lock case (203). Means for wirelessly sending (303) electrical power to the lock case and / or into connection with the lock case (203) are arranged in connection with the counterpart (101, 301) of the lock, and arranged in the lock case and / or in connection with the lock case (203) are means for wirelessly receiving (205) electrical power from the means for sending electrical power that are arranged in connection with the counterpart of the lock. The counterpart (101, 301) of the lock wirelessly sends electrical power to the lock case (203) and / or into connection with the lock case with the means that are for sending (303) electrical power, and the lock case (203) wirelessly receives electrical power from the counterpart of the lock with the means that are for receiving (205) electrical power, when the lock (102, 202) and the counterpart (101, 301) of the lock are at a certain distance from each other. In the method 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.
Description
technical field [0001] The invention relates to a door lock and an arrangement for transferring power to a door lock. Background technique [0002] Door locks comprising a housing and a deadbolt which can be opened and closed mechanically are known in the art. There are also electric locks in the art that can be opened and closed controlled by means of electrical commands and electrical opening means. In arrangements known in the art, the electrical connection of the lock in the door is arranged for example by means of electrical wires or other corresponding wires passing through the door frame. The wires can for example run from the hinge side of the door via the door frame to the door lock. [0003] Guiding the wires requires a passage in the door for the wires, and in this case conventional doors cannot be used with electric locks without retrofitting the door. In their current state, ordered special doors must be used for doors provided with electric locks, said doors...
