Definitions

  • the present invention relates to a combination of cylinder key and an associated transmitter according to the preamble of claim 1.
  • EP 0 187 363 B1 discloses a possibility according to which the data exchange takes place via a detector / counter-detector which is seated on the key head / lock cylinder.
  • the data exchange basically wirelessly and from the wider environment of the transmitter and the receiver out.
  • an electronic monitoring device is connected to the key, which cooperates with a counterpart on the lock cylinder.
  • EP 0 224 607 B1 assumes that this makes identification of the respective key user possible, this idea can only be limited to the use of the correctly coded key.
  • the invention is based on mechanical identification of the key with a unique personal Unikatkennung, from which only the access authorization for the present key arises.
  • the personal identification is processed so that a data comparison is always readily possible.
  • the electronic identifier is thus clearly assigned to a specific key user. Each key is thus a unique to a specific person bound.
  • the electronics for the identifier so far queries the authorization of the user to guide the key and recognizes the authorization in the case of daily practice.
  • the invention therefore uses the idea that person-specific features - if enough individual features are used - in this combination unique and therefore perfect are clear and must therefore be easily recognized in the case of daily practice.
  • the vortex and the bow are each viewed right, left.
  • the sensor detects immutable biometric data.
  • processor and memory on the key handle in the simplest case - if access authorization has been established - a release signal will be given to the lock cylinder.
  • the coded signal can then be transmitted via a transponder circuit to the lock cylinder.
  • Such a chip can be arranged directly on the key head or by means of a chip carrier, which in turn is connected to the key head.
  • the sensor of individual sensor elements is assembled matrix-like and should be known as a fingerprint sensor (see, for example, Siemens).
  • Such a sensor is quite suitable for the present application, because after determining the basic pattern (loop, whirl, bow) only still requires the determination of up to eight anatomical features in order to come to a clear statement about the access authorization.
  • Such a sensor since such a sensor is extremely flat, it can be easily integrated into a key head, preferably in conjunction with a transponder, which - if the fingerprint matches - transmits a coded signal to the lock cylinder.
  • the figures show a cylinder key 1, consisting of key shank 2 and key head 3. On the key head 3, the large side surfaces are designated grip surfaces 3a, 3b.
  • the key shank 2 carries a mechanical identifier, formed from notches 4 on the key shank 2 for alignment of not shown mechanical tumblers, which are housed in the associated lock cylinder 5, and which are spent by the incisions - if the mechanical identifier is authorized to enter - in the release position.
  • Such mechanical tumblers are state of the art. They sit in holes of the lock cylinder 5 and are spring-loaded in the direction of the lock core 6. Each tumbler element consists of two subelements, which touch each other.
  • the closing element 6 facing the sub-element is held by an associated recess 4 of the key shaft so in a depth position that the contact zone between the two sub-elements is precisely aligned in the parting line 7 between the lock core 6 and lock cylinder 5.
  • the lock core 6 is rotatable within the lock cylinder 5 as soon as all mechanical tumblers 8 sit with their mutual contact zones in the parting line 7.
  • this lock cylinder has a device which causes an additional release / Freihaltetress in the lock cylinder only when access authorized key.
  • the additional device is realized here by an electromagnetically driven locking pin 9, which is acted upon by a control device 10 so that it is pulled out with access authorized key out of engagement with the lock core but otherwise is in engagement with the lock core.
  • the energy source 11 required for this purpose can be accommodated in the lock cylinder 5.
  • the activation of this device is dependent on the output of an electronic Identifier for the individualization of the key.
  • the additional electronic identifier is provided by a sensor 13, which is arranged on one of the grip surfaces 3a of the key head 3 for detecting predetermined person-specific data of the current key user, and that the sensor 13 cooperates with a transmitter 12 with data memory 14, where the currently available data is compared with previously stored data in the data memory 14, and that only in the case of a predetermined amount of correspondence between the current individual data and the stored individual data, a signal for triggering the additional release / Freihaltetress is generated.
  • the senor 13 is arranged on the visible side surface of the cylinder key 1 approximately where the user lays his thumb.
  • the sensor is used for digital acquisition of individual data of the thumbprint.
  • the output of the sensor 13 is connected to a processor 12 where the data received from the sensor 13 are compared with corresponding data stored in the electronic data memory 14.
  • the processor maintains a mathematical mapping rule programmed so that the exact geometric orientation of the current person-specific data in the sense of congruence with the data stored in the memory 14 for determining the access authorization by the processor.
  • the processor determines the coincidence or a predetermined degree of coincidence between the mutual data, the signal for triggering the release / release action can be given.
  • a data transmission device 20 which is arranged on the key head and which corresponds to a data transfer device 21, which is arranged in the lock cylinder 5, is used.
  • the processor has a corresponding
  • the data transmission device 20 it has been proposed to form the data transmission device 20 as a transponder which gives a coded signal which is not easy to copy.
  • the present state of electronic data processing makes it possible to detect the data acquired by the processor in any geometric angular position and in any translational position and to subject it to a mathematical mapping in the processor, so that the current angular position and the current translational position in the sense the stored angular position and the stored translational position is aligned.
  • the senor 13 is constructed in the manner of a matrix. For example, sensors have become known which have arrays of 256 x 256 sensors. The resolution is 500 dpi.
  • FIG. 2 shows a deviating embodiment.
  • the data collected by the sensor is e.g. transmitted via a bus line to the lock cylinder, where the processor 12 and the data memory 14 sit.
  • FIG. 3a shows a sensor 13, which is integrated together with an underlying processor 12 and a memory 14 located below it in a single chip, wherein the chip disappears as a compact unit in a countersink 22 of the key head 3.
  • the overall height of the entire chip is so small that the sinking 22 only claims a portion of the material thickness of the key head 3.
  • the chip can be held in the recess 22 with a radial clamping device.
  • the chip carrier 16 has a latching toothing 17, which can engage in the recess 22 engaging behind.
  • FIGS. 4a to 4c show arrangements of the chip carrier in a separate holder 18 which is located on the grip surface 3a of the key is positioned and held there.
  • the holder 18 engages around the key head 3 of two opposite sides with a kind of clamping 23, so that the holder sits immovably firmly on the key head 3.
  • the adjacent clasps of the two holders only mesh like a tooth, so that alternately one tooth of one holder and another tooth of the other holder follow each other.
  • data transmission devices in particular transponders 20, can also be integrated into the holder.
  • an energy source 11 can also be accommodated in the holder.
  • a method for checking an access authorization to a mechanically and additionally electronically coded cylinder lock which is to be operated with a mechanically and additionally electronically coded cylinder key.
  • an authorized user electronically stored biometric data and recorded upon actuation of the cylinder lock the corresponding biometric data of the current user and then causes the electronic coding to trigger a release / Freihalte risk in the cylinder lock, if independent of the translational and rotational position of the biometric data results in a predetermined degree of correspondence between the biometric data of the current user and the biometric data of the authorized user.
  • the current biometric data are recorded on the cylinder key and transmitted to the cylinder lock, where they are checked by a processor arranged there, from where the signal for triggering the release / Freihaltetress is output to the corresponding device.
