Definitions
- the invention relates to a key for a cylinder lock and a cylinder for a key as described in claims 1 and 11.
- Keys are already known which are formed from a key handle and a key shank.
- the key shank is provided with the coding for the cylinder, with a wide variety of prongs, indentations and indentations being used for this purpose, with a key channel of the cylinder being designed correspondingly to the design of the key shank.
- these mechanically coded keys can also be provided with electronic coding in the form of NVC chips or RFID chips by arranging the chips on the key handle and protecting them with a plastic cover.
- the key according to the invention is characterized in that a receiving opening is arranged in the key shank, in particular at the opposite end to the key handle, in which a chip, in particular an RFID or NFC chip, is arranged and fastened.
- the advantage here is that the user can grip the key handle with his fingers without covering a chip and thus reducing the reception range minimize. This significantly increases user-friendliness, since the key can be gripped and used as normal and the key shank can simply be held against the query electronics to use the electronic coding, i.e. the NFC or RFID chip.
- both a mechanical coding and an electronic coding can be used with one and the same key.
- These two systems, in particular the mechanical coding and electronic coding can be used independently of one another or together during activation of the cylinder, whereby double security is achieved, since both the mechanical coding of the key for opening the cylinder must be correct, i.e also the electronic coding, which can also be queried in the cylinder.
- the chip is rectangular, square or round. This means that commercially available chips can be used, with a corresponding receiving opening in the key shank only having to be punched, milled, drilled or lasered when the key is in the key blank. This means that the key can only be adapted to a wide variety of systems, in particular query electronics, at a very late point in time. In this case, it is namely possible that the mechanical coding is produced first and then the receiving opening for the chip. It has been found to be advantageous that first the receiving opening on Key shank, then the mechanical coding on the key shank are made and after the end of the mechanical work, the chip is used, in particular pressed in or glued in.
- the key shank has a rectangular shape in cross section for a corresponding rectangular key channel of a cylinder.
- a corresponding receiving opening can be produced in the key shank by lasering, punching or milling, whereupon the freely selectable chip required can then be inserted.
- the key blank is therefore preferably produced in large numbers without the receiving opening, whereupon the receiving opening is then adapted to the required chip and produced. It has been found to be advantageous here that the receiving opening is produced first, whereupon the mechanical coding is preferably produced by milling the corrugated path and only finally is the chip inserted by pressing or gluing.
- a design is advantageous in which a mechanical coding is arranged on the key shank, preferably in the form of corrugated paths, consisting of several coding elements. As a result, a very high degree of protection against counterfeiting is achieved, since such keys with wavy paths running in themselves cannot simply be copied with an image or 3D print.
- a design is advantageous in which the coding elements are designed in the form of parallel corrugated paths in the longitudinal direction of the key shank over at least a partial area of a length of the key shank.
- the use of coding in the form of waves or wave tracks results in an approximately rectangular shape of the key shank, so that a rectangular keyway is required on the cylinder.
- a design is advantageous in which the coding elements are designed in the form of parallel corrugated paths in the longitudinal direction of the key shank over at least a partial area of a length of the key shank
- An embodiment is advantageous in which coding elements are arranged on both side surfaces of the key shank, which are mirror-inverted. The result of this is that the best possible space utilization is utilized for the coding, so that a large number of different coding options are created. Furthermore, increased stability is achieved through the rectangular design of the key shank.
- Another advantage is that electronic NFC chips can be embedded in the key shaft, making it compatible for use with other electronic devices.
- coding for individual, main and/or group keys is possible via the coding elements are advantageous.
- a key can also be used for residential complexes, company buildings or even for individual households.
- By designing it as a master or group key access to different rooms can be easily controlled so that not everyone has access to every room, as is the case with a master key.
- the advantage is the reduction in the number of keys on the keychain. Fewer keys are required to operate the system.
- An embodiment is advantageous in which the coding is arranged by means of an 8-bit coding on the side surface of the key shank, with preferably 6 to 12 query positions being arranged.
- the address, any information or the name of the person can be translated to binary coding and the key can be encoded with it.
- Another advantage here is that you can code clearly using binary coding.
- an embodiment in which the key shank is only provided with the electronic coding is also advantageous.
- the advantage here is that the user can hold the key by the key handle as usual and the key shank is held against the query electronics or inserted into the electronic cylinder. This means that gripping the key by the key handle does not cover the chip with your fingers, so that the full range for chip recognition is retained.
- the object of the invention is also achieved by a cylinder for a key in which query electronics for reading a chip, in particular an RFID or NFC chip, are arranged in the cylinder core of the cylinder housing or in the cylinder housing, in particular in the cylinder bit, on the key shank of an inserted key is.
- the advantage here is that manipulation from the outside is no longer possible due to the integration of the query electronics in the cylinder. Furthermore, the interrogation electronics are positioned very close to the chip in the key shank, so that reliable identification is guaranteed. What is also achieved is that double security is provided on the one hand by the mechanical coding and on the other hand by the electronic coding.
- An embodiment is advantageous in which the query electronics are connected wirelessly or by wire to other controls, in particular access control, time recording, garage control, etc., which are activated when the mechanical and electronic identification of the key match
- the key channel for the key in particular the key shank, is of rectangular design.
- the advantage here is that this first creates the possibility of using an electronic coding in the key shank that does not protrude beyond the width of the key.
- FIG. 1 shows a schematic representation of a cylinder lock with an inserted key, in a simplified, schematic representation
- FIG. 2 shows a front view of a cylinder known from the prior art with a conventional keyway, in a simplified, schematic representation
- FIG. 3 shows a front view of the cylinder according to the invention for comparison with the cylinder according to FIG. 2 known from the prior art and its design of the rectangular key channel, in a simplified, schematic representation;
- FIG. 4 shows a side view of the key according to the invention with mechanical and electronic coding on the key shank, in a simplified, schematic representation
- FIG. 5 shows a sectional view through the key shank with the mechanical and electronic coding according to FIG. 4, in a simplified, schematic representation:
- the locking lug 3 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 also turned and, for example, when the cylinder lock 1 is installed in a door (not shown), the rocker or the locking bolt is actuated via the driver 3 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 4 and a key shank 5 .
- the key shank 5 has a mechanical coding 7 on the side faces 6 .
- the coding 7 is formed by several individual coding elements 8, the coding elements 8 being formed from individual elevations 8a and depressions 8b.
- the successive coding elements 8 of the coding 7 preferably form corrugated paths 9 running in the longitudinal direction of the key shank 5, in particular 8 parallel corrugated paths 9, so that an 8-byte encryption is achieved.
- the same mechanical coding 7 is used on each side surface 6 of the key shank 5, but this is rotated by 180°, so that the key 2 can be inserted into the cylinder lock 1 in any direction.
- the key shank 5 is rectangular, i.e. the outer circumference of the key shank 5 has a rectangular shape and does not have any prongs, indentations or the like, as is the case in the prior art.
- the key 2 in particular the key shank has a serrated design, as can be seen from a key channel 9 of the cylinder 1 shown. This jagged design corresponds to the usual coding of the key 2 from the prior art.
- an electronic coding 10 is also arranged on the key shank 5 in addition to the mechanical coding 7 .
- This additional coding type is One and the same key 2 can be used for both a mechanical access system and an electronic access system, which significantly increases user-friendliness, since, for example, in large hotels, a wide variety of systems are often used for the room door or the garage or sauna, etc., which means that only the one according to the invention can now be used Key 2 is required.
- the key 2 according to the invention differs from the prior art in that the electronic coding 10 is arranged in the key shank 5, whereas in the prior art it is always fastened in the key handle 4, which is then covered by a plastic protection.
- problems often arise when the key 2 is held on the key handle 4 , since this minimizes the transmission power through the fingers and the key 2 is therefore often not recognized, so that the user then holds the key 2 on the key shank 5 .
- the required key channel 12 on the cylinder 1 or cylinder lock 1 is designed in such a way that it has a symmetrical shape, in particular a rectangular shape, so that an electronic coding 10 can be used.
- the key channel 11, 12 reproduces an image of the mechanical coding 7 on the key shank 5, so that a rectangular shape of the key shank 5 is only possible through the development of the new key 2 with the wave tracks 8, so that an electronic coding can be used 10 on the key shaft 5 is made possible by integration into the material of the key 2.
- the user can thus hold the key 2 on the key handle 4 without loss of range for the electronic coding 10 and, for example, the key shank 5 to an electronic access system which, for example, holds out the key shank 5 to query electronics attached to the outside of a door, in particular on the door plate of a hotel door.
- the electronic coding 10 is formed in such a way that a receiving opening 13 is arranged in the key shank 5, in particular at the opposite end to the key handle 4, in which a chip 14, in particular an RFID or NFC chip 14, is arranged and fastened. It is advantageous if the chip 14 has approximately a width 15 of the key shank 5, ie the material thickness of the key 2, or less, so that the chip 14 does not protrude to the outside. If the chip 14 protruded beyond the key shank 5 in the width 15, it could be damaged on the one hand and on the other hand the chip 14 could damage other objects, for example the fabrics of trouser pockets, bags, etc. with the edges, in particular tearing. A significantly further disadvantage would arise for the key channel 12 in the cylinder 1, since this can then no longer be of rectangular design and the mechanical coding 7 would thus suffer losses.
- the invention provides that the cylinder 1 for the key 2 comprises at least one cylinder housing 16, a cylinder core 17 with the key channel 12, one or more locking disks (not visible) for querying the mechanical coding 7 being arranged in the cylinder core 17.
- the locking discs are mounted in a defined position in position slots of the cylinder core 17 and are arranged to be displaceable, the locking disc having at least one projection on the outer circumference and a corresponding recess for receiving the projection being arranged in the cylinder housing 16 in order to prevent the cylinder core 17 from rotating to lock or block relative to the cylinder housing 16 via the inserted key 2 and / or release it for a rotary movement.
- an electronic query system 18 is arranged for reading a chip 14 on the key shank 5 of the inserted key 2, i.e. the key 2 with the mechanical and electronic coding 7.10 is inserted into the cylinder 1, so that the mechanical coding 7 is queried via the locking discs and at the same time the electronic coding 10 is queried via the query electronics 18.
- the query electronics 18 are designed in such a way that they are connected wirelessly or by wire to other controls, in particular an access control, a time recording, a garage control, etc., which are activated when the mechanical and electronic identification of the key 2 match.
- the key 2 can also only have the electronic coding 10 on the key shank 5 , which in turn is inventive compared to the prior art, since the keys from the prior art only have electronic coding in the key handle 4 .
- a design of the key 2, in particular the flat key 2, has proven to be advantageous in which four to eight parallel wave tracks 8 are arranged, which are queried up to six positions via two locking disks per position in the cylinder (not shown).
- the invention is not limited to the illustrated embodiment variants, but can also include other configurations.
- the design variants or individual features of the design variants can also be combined with one another.
