Definitions

  • the invention relates to a key for an electronic or mechatronic lock - key system according to the preamble of claim 1 and a lock - key system according to the preamble of claim 4.
  • the invention has for its object to provide a lock - key system with a key in which a 13.56 MHz RFID medium can be read without contact, and its manipulation security is improved.
  • the realization of the contactless readout with a fully inserted key requires a relatively large antenna area for the current RFID media (13.56 MHz). In this case, no metal key can be used as the metal of the key would make reading impossible.
  • the antenna can also, as already known, be integrated into the key crayons. There is the problem of reading, as arranged in the cylinder core reading antenna is difficult to read about this distance / angular position of the medium.
  • the 13.56 MHz RFID antenna can be embedded in a ceramic key shank. Technical ceramics are no longer brittle today; they can even reach a certain elasticity (as in knife cutting). Therefore, the key shank may consist of technical ceramics in which an antenna made of tungsten wire is inserted.
  • the antenna wire must have a high temperature resistance, because after molding and pressing the ceramic must be fired.
  • the ends of the tungsten wire would then be out of the Reide facing part of the key shaft protrude and are then connected to the RFID chip.
  • the RFID chip is arranged in the plastic recess of the key, which then surrounds the ceramic key shank in a form-fitting manner.
  • the power supply for the core electronics can be accommodated in the cylinder housing.
  • a material query / review is integrated into the cylinder core.
  • This material query should query the properties of the ceramic, so the hardness and the smooth surface.
  • a hardened plate can be used, which slides a sharp edge over the ceramic surface when the key is inserted. By spring force presses this hardened edge on the key shaft and is brought from the key surface in a certain position in which it releases a tumbler, which is arranged in the cylinder housing. If a key were used with plastic shaft, then the edge of the plate would "hook” and significantly hinder or prevent the further key insertion, and not reach the required position to release the tumbler.
  • the key shank can be made of technical ceramics (different colors are possible -white, blue ).
  • the key shank can include the RFID antenna as it is made of non-conductive ceramic It is also possible to incorporate features such as profiling or constant coding into the mold.
  • the usual components of a lock - key - system are the key 1, the lock cylinder 5 and the rotatably mounted in this cylinder core 6.
  • the cylinder core has a keyway into which the key to perform a closing operation is inserted.
  • a plate 7 is with its run-on slope 13 slightly into the closing channel and is held by a pin 8 in its position. His leadership 11 in the cylinder core 6 allows for tilting; as well as its bore 12, which is larger than the passing therethrough pin 8.
  • the spring-loaded housing pin 10 presses on a convex pin 9, the plate 7 in the direction of the closing channel.
  • Fig. 2a shows an enlarged section of the spring-loaded pin 10 which is arranged in the cylinder housing 5. This pushes by its spring 15 the spherical pin 9 in the direction of the closing channel.
  • Fig. 3 also shows the section AA, however, the key is now fully inserted, the sharp edge 14 of the plate 7 "scratched" when inserting the key over the surface and thus checks the surface texture and hardness, since the plate is spring loaded,
  • the plate 7 is in a position in which the pin 9 presses the spring-loaded pin 10 so far into the cylinder housing 5, that the cylinder core 6 can be rotated.
  • the electronics 4 is arranged so that the antenna of the key can communicate with the antenna of the electronics.
  • Fig. 4 shows the front view of the profile cylinder with inserted key (1).
  • section line BB drawn.
  • Fig. 5 shows the section BB, the key with its integrated antenna 3 can be seen.
  • the key bit 18 made of plastic surrounds the ceramic key shank 16.
  • the RFID chip 2 which is connected to the antenna 3.
  • the power supply 17 for the arranged in the cylinder core electronics 4th
  • Fig. 6 shows the key with plastic Reide 18 and ceramic shaft 16 in which also profile features 19 and / or coding features 20 may be present.
