Definitions

  • the invention relates to a locking device an electronically coded key according to the generic term of claim 1.
  • Such a locking device is from DE 195 17 728 A1 known.
  • the locking cylinder is with a cylinder bag provided, the actuator designed as an electric motor receives.
  • the key channel is to the peripheral surface of the Open cylinder core.
  • the locking element is a bracket trained, which with its two ends in two Recesses in the peripheral surface of the cylinder core on the one or the other side of the open key channel in the axial area of the Engages the cylinder core.
  • the trained as an electric motor The electric motor arranged in the cylinder bag has a shaft two opposite cams on in the locked position engage on the bracket or on the cylinder housing.
  • the known locking device with electronic-mechanical encoded key has been on the whole proven. However, the entire cylinder lock needs to be replaced become. Also only cylinder locks with cylinder bags be converted to this locking device.
  • DE 42 07 161 A1 discloses a locking device with a Lock cylinder emerged, in the form of a additional coverage an additional electronic Lock is provided. This contains a cap, which rotates with the cylinder core.
  • DE 297 03 063 U1 is an additional electromagnetic Locking for the cylinder core known, which in Recesses attacks on the circumference of the cylinder core.
  • the object of the invention is practically all Cylinder locks in one without having to replace them such locking device with electronic, in particular to convert electronic-mechanical coding.
  • the invention is based only on the idea that electronic coding of the key to access the Key channel in the cylinder core with the armored disk too check.
  • the lock cylinder according to the invention provided with such cylinder armor.
  • the Cylinder armor contains the actuator in the tank housing as well as the blocking element which he can actuate, in one such an arrangement that it is in the locked position on the Armor plate attacks in its rotation preventing Release position releases the armored disk.
  • the armored disk prevents access to the key channel in the Cylinder core with a screw or the like. Breaking tool.
  • the armored disk has the function, one Rotation of the cylinder core only if applicable electronically allow encoded key.
  • the locking member preferably engages in a recess on Circumference of the armored disk. It is in its locked position preferably spring-loaded. The power to engage the Locking organ in the locked position, i.e. in the recess in The circumference of the armored disk is thus by the spring applied. The disengagement of the locking member from the recess in the armored disk, thus releasing the rotation of the Armored disc, done by manual force when turning of the key inserted in the cylinder core.
  • sliding surfaces or Rolling elements for example a ball or a roller on Blocking member or be provided in the recess.
  • a ball or a roller on Blocking member In order to sets the blocking organ in the blocking position of a violent Rotation of the armored disk counteracts a high shear force. On the other hand, it slides or rolls out of the recess and then over the circumference of the armored disk if the Cylinder core is turned with the key.
  • the actuator can be an electromagnet, for example. However, it is preferably by an electric motor formed which moves a limb in the locked position preferably both on the locking member and on the tank housing attacks.
  • the actuator is thus bi-stable. That is, the Electric motor has both in the locked position as the Release position of the armored disk in a de-energized state on.
  • the link that is moved by the electric motor can Mother of a worm gear, which in the Armored housing is slidably guided and into which a thread engages on the motor shaft. It is also possible to link for example as an eccentric on the camshaft to form two opposing cams, the two cams in the locked position of the armored disc on the Support the locking device or the tank housing.
  • a battery of the actuator or motor can be provided, that can be placed in the door.
  • the power supply in the cylinder armor integrated, for example a button battery in the Armored housing provided.
  • the code evaluator in be arranged in the tank housing.
  • the main advantage of the invention is therefore that the locking cylinder already in the door is completely can remain unchanged because only the cylinder armor with the locking member and the actuator and, if necessary, the electronic code interpreter and the Power supply unit on the lock cylinder on the security-endangered, i.e. put the outside on and on needs to be attached to it.
  • the cylinder armor can be dimensioned so that it fits on almost every locking cylinder. It is with it fabrikat independent. That is, practically everyone Lock cylinder, as for example Euro profile, round or Oval cylinder is easy to assemble at any time retrofittable according to the invention.
  • Cylinder locks with a cylinder core like Double cylinder locks retrofitted with two cylinder cores can be.
  • the cylinder core on the security end for example on the Outside of a door, with the invention Cylinder armor provided.
  • the cylinder core on the inside of the door is then only through the mechanical coding of the key can be unlocked.
  • the key can only be electronically encoded.
  • electronic coding generally only provides one additional code to the mechanical code of the key.
  • the electronic code transmitter in the key is preferred through a transponder and the electronic code interpreter in the cylinder armor, preferably by a Transponder reading device, formed.
  • the Key preferably a ferrite antenna. If he as Reversible key is formed, are two ferrite antennas provided, one on one and the other on other side of the key bow. The arrangement of the Ferrite antennas on the tank housing and on the key so that when the lock cylinder is inserted Key only a narrow air gap between the Ferrite antenna in the tank housing and the ferrite antenna of the Key arises, so that only minimal transfer Energy losses occur.
  • the transponder reading device comprises a microprocessor and a non-volatile memory. Furthermore, in generally a clock for the date and time function with a quartz oscillator is provided as a time base. The actuator is controlled directly by the microprocessor.
  • the locking element moves the Actuator in the locked position.
  • the in Lock cylinder inserted key moves Ferrite antenna of the key but also of the ferrite antenna away in the tank housing. That said, you wouldn't get any additional Take action if the actuator were to turn the Actuated lock cylinder, and he would try that Push the locking device into the locked position.
  • the actuator when turning the A twist sensor for example a piezo element or a switch Detection of the rotational position of the armored disk or the Cylinder core may be provided. Because when turning the Armor plate or the cylinder core itself in the locking element the release position, the switch is preferred trained so that it is actuated by the locking member, if this is in the release position.
  • locking cylinder is according to the invention to interpret widely.
  • the invention extends also on rotatably mounted carriers in a housing, if the driver has a recess, e.g. a Polygonal recess, has a key-like tool, e.g. with polygon, is pluggable.
