View Patent ↗A key lock which can be used particularly flexibly and cost-effectively has a communication device for wire-free linking of the key lock to an actuating mechanism. The key lock further has a cable-independent power supply device for autonomously providing the electrical power required for extended operation of the key lock.
1. A key lock, comprising:
a communication device for wirelessly linking the key lock to a signal box;
a line-independent power supply device for autonomously providing electrical power needed for operating the key lock;
a sensor device for detecting a presence or non-presence of a key of the key lock and the key lock wirelessly transmitting an information signal via said communication device, specifying a presence or a non-presence of the key, to the signal box; and
an actuator device for releasing or blocking a removal of the key from the key lock and the key lock wirelessly receiving a release signal, from the signal box, specifying permission or the blocking of the removal of the key.
2. The key lock according to claim 1 , further comprising an electronic control device.
3. The key lock according to claim 2 , further comprising a communication link connecting said communication device to said electronic control device.
4. A key lock configuration, comprising:
a signal box;
a key lock containing a communication device for wirelessly linking said key lock to said signal box, said key lock containing:
a key;
a sensor device for detecting a presence or non-presence of said key and said key lock wirelessly transmitting an information signal via said communication device, specifying a presence or a non-presence of said key, to said signal box; and
an actuator device for releasing or blocking a removal of said key from said key lock and said key lock wirelessly receiving a release signal, from said signal box, specifying permission or the blocking of the removal of the key;
a line-independent power supply device for autonomously providing electrical power needed for operating said key lock; and
at least one switching element secured by said key lock.
5. The key lock configuration according to claim 4 , wherein said switching element is selected from the group consisting of a switch, a track lock, a barrier, a signal and a signal lever.
