Abstract: 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.

Abstract: Lock arrangement and method for detecting the presence and location of a device sending a radio signal, which lock arrangement includes a lock case that can be fixed into a door, which lock case includes a locking latch and a latch mechanism. The lock arrangement further includes at least two antennas fitted into connection with the lock arrangement and a device for receiving radio signals connected to the antennas. The lock arrangement is able to determine on the basis of the signals measured from the antennas on which side of the lock arrangement the device sending a radio signal is located.

Abstract: Lock arrangement including a counterpart of the lock and a lock with a lock case. The lock case, which can be installed in a door, includes a locking latch and a latch mechanism, which includes an electrical device for opening and/or closing the locking latch. The counterpart of the lock can be installed in the frame of the door. A device for wirelessly sending electrical power to the lock case and/or into connection with the lock case is arranged in the counterpart of the lock; a mechanism is arranged in connection with the lock case for wirelessly receiving electrical power from the device for sending electrical power that is arranged in connection with the counterpart of the lock. Electrical power is arranged to be transmitted from the device for sending electrical power to the mechanism for receiving electrical power, when the lock case and the counterpart of the lock are at a certain distance from each other.

Abstract: Door lock including a pivoted latch with a striking plate disposed in the doorframe opposite the door, into which striking plate the pivoted latch is arranged to turn in the locking position; In addition, a locking slide for turning the latch is provided. Installed into the lock is a tightening part which directly or indirectly wedges the locking slide farther away and thereby turns the latch farther into the striking plate when the door is pushed closed.
