Definitions

  • the invention relates to a key for a cylinder lock and a coding system for a key as described in claims 1 and 8.
  • Keys in particular flat keys, are already known in which a coding, in particular coding elements, are attached to the key shaft and are queried via locking plates in a cylinder lock.
  • the coding elements can take place on the one hand via incisions, in particular serrated indentations, on the end faces of the key shaft or via depressions, in particular bores, on the side surface of the key shaft.
  • the disadvantage here is that such codings are very coarse and the usual incisions or usual bores can be imitated with a relatively simple tool.
  • a laterally attached indentation, such as: curves, are a bit better, but this key can also be copied relatively quickly through photography and conventional 3D printers.
  • the method according to the invention is characterized in that the coding elements are designed in the form of corrugated tracks formed parallel in the longitudinal direction of the key shaft over at least a partial area of a length of the key shaft, several coding elements being arranged next to one another
  • the advantage of this is that a shaft or curve, which form the coding elements, is milled into the narrow side of the key in the longitudinal direction of the key bit or key shaft.
  • the special feature of the invention is to superimpose the depressions of the waveform and preferably more than one per side in order to increase the variation of the key.
  • a design is advantageous in which coding elements are arranged on both side surfaces of the key shaft, which are designed as mirror images. This ensures that the greatest possible utilization of space is used for the coding, so that a large number of different coding options is created. Furthermore, the rectangular design of the key shaft increases stability.
  • the designs are advantageous in which coding for individual, main and / or group keys is possible via the coding elements.
  • a key can also be used for residential complexes, company buildings or even for individual households. Because it is designed as the main or group key, access to different rooms can be easily regulated, so that not all people have access to every room like this is the case with a master key. This reduces the number of keys on the bunch of keys. Fewer keys are required to operate the system.
  • the coding elements in particular the corrugated track
  • the coding elements are milled in the form of depressions, with several depressions being arranged one after the other in the longitudinal direction.
  • this increases the security against forgery, since, due to successive waves that are arranged in several tracks one below the other, blur into one another and, on the other hand, a space-saving coding can be implemented.
  • An embodiment is advantageous in which the coding elements, in particular the depressions in the corrugated track, are designed to be superimposed and preferably more than one per side. This also makes a replica more difficult.
  • the coding elements in particular the depressions in the wave path, are formed by a sine wave or a cosine wave.
  • the coding can only be produced using a special production process, in particular milling. This means that it is impossible to use commercially available tools such as a drill, wax impression, file, etc. to imitate such a shaft key.
  • the coding elements in particular the depressions in the wave path, are formed by interference.
  • This further increases the security against forgery. You can't see the wave very well, you can only see the rest of the material that is left over when you lay several waves on top of each other for coding. A wave could possibly be guessed because it has recurring wave troughs and wave crests.
  • the interference is milled into the key shaft. The negative imprint of the milling pattern, which is an interference pattern of several waves, remains in the key shaft.
  • the object of the invention is also achieved by a coding system for a key in which an 8-bit coding is arranged on the side surface of the key shaft at each query position, with at least two query positions, in particular 6 to 12 query positions, being arranged for a key.
  • This advantageously means that a large number of different coding options are created.
  • the address, any information or the name of the person can be translated to binary coding and thus the key can be encoded.
  • Another advantage here is that it can be uniquely coded using binary coding.
  • an embodiment is also advantageous in which the coding, in particular coding elements, are in the form of corrugated tracks formed parallel in the longitudinal direction of the key shaft over at least a partial area of a length of the key shaft, with several coding elements being arranged next to one another.
  • the advantage here is that the protection against forgery is increased due to the wave shape.
  • a longitudinally extending wave track can be adapted to the shaft width of the key through the width of a milling so that for the first time 8 parallel query points or wave tracks are possible. There are 8 waves, whereby these waves are scanned on 12 frets or query positions. The collar or the query position then has 8 waves at this position that corresponds to the 8 bits.
  • a design is advantageous in which coding elements are arranged on both side surfaces of the key shaft, which are designed as mirror images. It is advantageous here that binary coding with 1 bit per query position is possible for the first time, so that the coding can also be personalized with regard to the user.
  • the key can be used in both directions (reversible key) without restricting the ability to vary.
  • An embodiment is advantageous in which coding for individual, main and / or group keys is possible via the coding elements. This creates a large area of application for the key. It also enables overarching lock hierarchies. One person only receives one key with which individual access to the entire system is enabled
  • An embodiment is advantageous in which the coding elements, in particular the corrugated track, can be produced by milling, which are designed in the form of depressions, with several depressions being arranged one after the other in the longitudinal direction. In this way, the coding can be produced by milling. An increase in the coding options can thus also be achieved due to the wide variety of depths.
  • a design is also advantageous in which the coding elements, in particular the depressions of the corrugated track, are designed to be superimposed and preferably more than one per side. A simple forgery based on a recorded image is therefore hardly possible any more.
  • An embodiment is advantageous in which the coding elements, in particular the depressions in the wave path, are formed by a sine wave or a cosine wave. This also increases the security against forgery.
  • an embodiment is advantageous in which the coding elements, in particular the depressions in the wave path, are formed by interference from wave paths running parallel in the longitudinal direction.

  • FIG. 2a shows a side view of the key according to FIG. 2 with schematically drawn locking disks of the cylinder lock, in a simplified, schematic representation;
  • FIG. 3 shows a sectional illustration through the key shaft according to FIG. 2, in a simplified, schematic illustration
  • FIG. 4 shows a schematic representation for the locking method of the key with wave-shaped coding, in a simplified, schematic representation
  • FIG. 5 shows a plan view according to FIG. 4, in a simplified, schematic illustration
  • FIG. 6 shows a schematic illustration of a special coding for the key on the key shaft, in a simplified, schematic illustration.
  • FIGS. 1 to 6 in particular in FIG. 1, a cylinder lock 1 is shown with an inserted key 2 according to the invention, the representation of a catch or a locking lug on the cylinder lock 1 being dispensed with.
  • the locking lug or the driver has the task that when the cylinder lock 1 is released, i.e. when the inserted key 2 can be turned, the driver is turned along with it and, for example, when the cylinder lock 1 is installed in a door (not shown), the rocker or the locking pin is over the driver is operated so that the door can be opened or closed.
  • the key 2 according to the invention is preferably designed as a flat key which consists of a key handle 3 and a key shaft 4.
  • the key shaft 4 has a coding 6 on the side surfaces 5.
  • the coding 6 is formed by several coding elements 7, the coding elements 7 being formed from individual elevations 7a and depressions 7b. It should be mentioned here that the same coding 6, but rotated by 180 °, is used on each side surface 5 of the key shaft 4 so that the key 2 can be inserted into the cylinder lock 1 in any direction. If different codings 6 were used on the side surfaces 5 of the key shaft 4, the coding options are doubled, but the key 2 must always be correctly inserted into the cylinder lock 1 in order to be able to operate the cylinder lock. Such a training would of course be possible, but this is not very user-friendly for the customer or user.
  • the coding 6 is specially designed in order to make the reproduction more difficult.
  • the coding elements 7 are in the form of corrugated tracks 8 formed parallel in the longitudinal direction of the key shank 4 over at least a partial area of a length 9 of the key shank 4, several coding elements 7 being arranged next to one another, that is, at least two parallel corrugated tracks 8 are arranged with at least two coding elements 7.
  • An embodiment of the key 2, in particular the flat key has proven to be advantageous in which four to eight parallel corrugated tracks 8 are arranged, which are queried over six positions 10 via locking disks in the cylinder (not shown), as shown schematically with rectangular dashed lines Locking disks 11 or locking disk symbols 11 is shown.
  • Two locking disks 11 are always used at each position 10, so that there are 12 query positions. This means that four to eight interrogation points of the locking disks 11, which are located one below the other, i.e. vertical, are formed for each position 10 and locking disk 11, so that a coding 6 of 4 to 8 x 12 different possibilities or interrogation points result to which an elevation 7a or a Indentation 7b or a neutral position 7c are arranged in the form of the waves. A very high number of different options for coding 6 is thus created.
  • the key 2 according to the invention with corrugated tracks 8 is fixed in such a way that the narrow side, i.e. the side surface 5, of the key 2 is milled in the longitudinal direction of the key shaft 4, with a shaft or curve as the coding element 7, in particular elevation 7a, recess 7b or neutral position 7c is formed.
  • the different coding elements 7 can be formed due to a milled depth, the milling being formed or milled continuously, i.e. without interruption, over the length 10 of a corrugated track 8, so that a continuous corrugated track 8 is formed from nothing but intermingling arcs .
  • the key 2 is fastened or inserted in a clamping device (not shown) and then the key shaft 4 is worked by a milling cutter 12, in particular a milling disk 12a or end mill, which corresponds to the width 13 of a corrugated track 8, the milling cutter 12 corresponding to the required depth 14 is adjusted accordingly in order to generate a corresponding wave path 8 after the other.
  • a milling cutter 12 in particular a milling disk 12a or end mill, which corresponds to the width 13 of a corrugated track 8
  • the milling cutter 12 corresponding to the required depth 14 is adjusted accordingly in order to generate a corresponding wave path 8 after the other.
  • any other type of processing such as, for example, a laser with the corresponding material, can be removed, is possible for the production of the key 2.
  • the key 2 in particular a key blank, is clamped in a holder, whereupon the milling cutter 12, in particular the disk-shaped milling cutter 12, on the first wave path 8 at the beginning of the Key shaft 4 is positioned, whereupon the milling cutter 12 mills a horizontally running corrugated track 8 over the length 10 into the key shaft 4 with different depths 14, the milling cutter 12 being placed closer, deeper or further away from the key shaft 4 depending on the required coding element 7 so that the milling cutter 12 generates the coding elements 7, which are designed as shafts, by means of a coherent corrugated path 8, whereby the coding 6 is generated by the different elevations and depressions.
  • the processing is preferably carried out fully automatically by a computer-controlled milling machine, with software being installed for this purpose, in which one randomly or deliberately entered or created a code 6, whereupon the key blank is automatically processed, that is to say that only the blank is inserted into a fold or a clamping device must be inserted, whereupon one corrugated track 8 after the other corrugated track 8 is milled into the side surfaces 5 of the key shaft 4.
  • the milling machine interrupts the machining process so that the key 2 can be turned if there is no automatic turn, whereupon the second side surface 5 is created, so that the same coding 6 is preferably applied to both sides.

  • a key 2 and subsequently the associated cylinder lock 11 are thus binary-coded and encrypted / encrypted according to the “AES algorithms (Advanced Encrypting System)”.
  • the encryption corresponds to a 96-bit representation on key 2, whereby the key milling has a matrix of 12x8 bits and the whole thing can be coded by 3 path depths, so that a key 2 can be calculated and produced using 96-bit / 256-bit.
