Definitions

  • the invention relates to a flat key made of metal with a transponder as a code transmitter according to the generic term of claim 1.
  • Such a flat key is for example from GB-2,273,128 A known.
  • the encoder is together with the ferrite antenna in a recess in the tip of the Key shaft provided. This can be a significant one Part of the shaft does not have locking recesses for the tumblers of the castle.
  • the object of the invention is a flat key with a Provide transponder as a code transmitter that both in its external dimensions like the strength of a conventional one Flat key corresponds.
  • the flat key according to the invention has the same dimensions, in particular the same thickness as a conventional one Flat key (without code transmitter) for cylinder locks on. He is wearing a keychain, for example no more than a normal flat key. By the same outer shape, the same look and the same Dimensions like a normal flat key also fall not on that it is in the flat key according to the invention is a key with a code transmitter.
  • the invention Keys in the same way as a conventional one Flat key handled without code transmitter.
  • the groove-shaped recess in the narrow side of the Key chalk according to the invention is preferably a carrier inserted the encoder, the ferrite coil and the line for connecting the encoder to the ferrite coil having.
  • the inserted carrier is in the recess glued or poured with a mass.
  • the code transmitter or data carrier of the invention Key preferably has a read / write memory on.
  • the encoder can be on one with the ferrite antenna connected circuit board may be arranged.
  • the key according to the invention is preferably for a cylinder lock determined, whose stored in the cylinder housing Cylinder core is provided with a key channel, the mechanical one Tumblers to lock or unlock the cylinder, an actuator arranged in the cylinder housing for Moving a locking or releasing the cylinder core Blocking element and a power supply unit, preferably in the cylinder housing one by one Transponder reading device formed code evaluator provided is that controls the actuator and the locking member in at least one on the circumference of the cylinder core at a distance recess arranged in the key channel in the Axial area of the cylinder core that engages with the mechanical Tumblers is provided.
  • a cylinder lock is based on the German patent application 195 17 728.2 forth.
  • the transponder reading device has a ferrite antenna on, the free end up to the front of the cylinder housing enough.
  • the ferrite antenna is preferred as a pot coil with its opening facing outwards trained, the pot for reasons of tamper resistance with a metal plate on the front of the cylinder lock is covered.
  • the key according to the invention is preferably a reversible key educated.
  • the groove-shaped extends Recess from a narrow side of the key shaft the entire narrow side of the key willow to the other Narrow side of the key shaft, being in the groove-shaped Recess on both narrow sides of the key chalk each a ferrite coil connected to the code transmitter via a line is provided.
  • This is included in the cylinder lock inserted key always one of the two ferrite coils the key of the ferrite coil of the transponder reading device of the cylinder lock opposite.
  • a non-reversible key can also be used Flat key according to the invention for increasing the energy consumption be provided with two ferrite coils.
  • the flat key according to the invention is primarily for a cylinder lock with an actuator determined how described above, but it can also be independent of one Cylinder lock can be used as a data carrier, i.e. for any other facilities that have a transponder reading and / or Have writing device, for example access control devices with a transponder reading device or as a data carrier for control devices to justify services.
  • the fact that it is in the groove-shaped recess in the The narrow side of the key is located on the disk or encoders enclosed on three sides by metal. This mechanically protects the encoder. Also points the key according to the invention is therefore not molded Plastic parts that can break off. So he owns high mechanical strength and, aside from the groove in the narrow side, made entirely of metal, is useful it neither comes off nor gets scratched.
  • a conventional Reversible flat key 2 made of metal has a groove-shaped recess 3 milled from one, the upper Narrow side 4 of the key shaft 5 around the entire Narrow side, i.e. the upper narrow side 6, that of the key shaft 5 opposite narrow side 7 and the lower narrow side 8 the key bow 1 to the other, i.e. the lower one Narrow side 9 of the key shaft 5 extends.
  • the key 2 is for a cylinder lock with one Armored case determined.
  • a broadening 10 provided, which is inserted into the cylinder lock Key 2 arranged in a slot in a disc is, which is rotatably mounted in the tank housing.
  • the groove-shaped recess 3 extends through the area the widening 10. It also indicates by a corresponding contour milling concave indentations 11 and 12 on the upper and lower narrow sides 6 and 8 of the Key chalk 1, with the indentations 11, 12 open towards shaft 5.
  • the one, in Fig. 1 upper indentation 11 can also be omitted.
  • the module shown in Fig. 2 the has a bow-shaped carrier 13, which accordingly the groove-shaped recess 3 from an upper section 14, a middle section 15 and a lower section 16 consists.
  • the outer edge 17 of the carrier 13 corresponds to the outer contour the key bow 1, its inner edge 18 of the contour of the bottom 19 (Fig. 4) of the groove 3 in the narrow side of the Reide 1.
  • the module with the carrier 13 is with a chip or data carrier 20 populates the encoder or transponder of the key 2 forms, further with the two ferrite coils 21, 22 and the lines 23, 24 which are the ferrite coils 21, 22 connect to the code transmitter 20.
  • the code transmitter 20 is in a pocket 25 between the Provided outer edge 17 and the inner edge 18 of the carrier 13, while the ferrite coils 21, 22 in longitudinal recesses 26, 27 arranged at the two ends of the bow-shaped carrier 13 are.
  • the top pocket 25 ' can also be omitted.
  • the carrier 13 is formed in one piece and is preferably made made of plastic.
  • the code transmitter 20 can on a Printed circuit board arranged in the pocket 25, the groove 28 and the pocket 25 'and attached to the two ferrite coils 21, 22 is connected.
  • the module i.e. the one with the code transmitter 20, the lines 23, 24 or the printed circuit board and the ferrite coils 21, 22 Carrier 13 is in the groove-shaped recess 3 in the narrow side of the Reide 1 inserted.
  • the key 2 can be used as a reversible flat key for a cylinder lock be formed, designated 29 in Fig. 3 is.
  • the cylinder lock can correspond to the German one Patent application 195 17 728.2 be trained.
  • the means that a cylinder core can be rotated in a cylinder housing stored, the key channel with mechanical tumblers provided to lock or unlock the cylinder core is.
  • the cylinder housing In the cylinder housing is an actuator for moving one the blocking element which locks or releases the cylinder core intended. Furthermore, is in the cylinder housing Electronic code evaluator arranged, which is the actuator controls. The electronic code interpreter is replaced by a Transponder reader 30 formed which is a ferrite antenna 31 has.
  • the ferrite antenna 31 is as Pot antenna formed, which with a plate 32 on the Front side of the cylinder housing is covered.
  • the entire Shaft 5 with locking recesses for the tumblers of the Cylinder lock 29 may be provided.
  • the key 2 can essentially the same torsional forces as a conventional one Pick up flat key (without code transmitter).
