Definitions

  • the invention relates to an electronic locking device consisting of a lock and key cards, the lock electronics of which have a data memory and which can be coupled to a data-retrieving, mobile printer which can be connected to the lock electronics and which has an insertion slot for the key cards, in which a card reader is arranged and which insertion slot is attached at its end has a socket device connected to the lock electronics for a card-shaped coupling element of the printer which can be inserted into the insertion slot and has electrical contacts.
  • Such a locking device is known from European patent EP-B-0 ⁇ 132 627.
  • EP-B-0 ⁇ 132 627 By using the insertion slot both for the insertion of the key cards and for the coupling element, a particularly clear and simple design is created, since a separate insertion opening for the connection to the mobile printer is unnecessary. This also enables a hidden arrangement of the socket device, which offers a certain protection against unauthorized manipulation. Nevertheless, with the known arrangement it cannot be ruled out that the lock's data memory is abused by an unauthorized person inserting a coupling element into the slot of the lock and thus establishing an electrical connection with the socket device.
  • Status data can thus be queried or printed out by means of the mobile printer, which provide information about which key cards are used to lock the lock and at what time It was determined whether only the key card had been inserted or whether the lock mechanism had also been operated and whether there were any malfunctions in the lock.
  • the information that can be queried is usually up-to-date, ie a current database is kept that continuously overwrites older data. It is understandable that the data that can be queried may only be accessible to authorized persons.
  • connection of the printer represents a special operating mode of the lock; in normal operation (access control operation), when a valid key card is inserted into the slot, the coding is queried and compared with the lap code. If the key card information queried corresponds to the values stored in the memory, a locking pulse is generated which enables the lock to be transferred to the release position. Locking devices of this type can thus be used wherever certain areas are only to be entered by authorized users.
  • a locking device of the type mentioned at the beginning is to be specified, in which data retrieval by unauthorized persons is made considerably more difficult.
  • the coupling element has a key card code and that in the insertion slot there is a slide which can be displaced with the coupling element by inserting it and which can be fixed by means of tumblers which, when the key card code is valid, are transferred to the release position and thus shift the slide into it Allow end position in which the contacts connect to the socket device. It is thus provided according to the invention that a coupling with the socket device can only be carried out if the coupling element has a valid key card code.
  • the coupling element is mechanically locked out, provided that it does not carry a final key card code.
  • the key card code can also be a special key card code which, in contrast to the conventional key card codes, controls the lock electronics in such a way that it outputs the desired data. If only the "usual" key card code is available, data transmission is blocked.
  • a locking device emerges from the unpublished German patent application DE-A-3 702 730, in which a slide is provided which can only be moved by means of a valid key card; however, the problem of not querying data of the electronic lock by means of a printer to be connected is not dealt with.
  • EP-A-0 024 242 shows a mechanically / magnetically operating lock in which tumblers can be shifted by means of magnetized areas of the associated key cards are, which release a slide, which leads to the release of the lock mechanism in its final displacement position.
  • this design has no "memory"; there is no lock electronics, so that no information about previous closings can be queried.
  • EP-A-0 ⁇ 0 ⁇ 24 242 and EP-A-0 62 132 627 cannot give any indication of the invention, because this would only lead to key cards, but not to a coupling element, in which either a hole code or a magnetic code would be available.
  • the coupling element has conductor track coatings which form the contacts on one side edge of the coupling element, extend essentially to the opposite side edge region of the coupling element while passing the key card code and are connected there with a cable leading to the printer.
  • conductor track coatings are many times thinner than insulated cables and are therefore practically non-bulky.
  • the end regions of the conductor track coatings themselves form the contacts, so that on the one hand a separate plug element can be dispensed with and on the other hand no measures to increase the thickness are taken in the contact region either.
  • the plug element known from the prior art on the other hand, leads to a correspondingly thick design, which can lead to jamming or damage to the corresponding devices in the insertion shaft.
  • the card reader is particularly at risk there.
  • An embodiment of the prior art for light scanning may be conceivable (but without excluding the risk of damage), as is realized in the subject matter of EP-A-0 ⁇ 132 627.
  • the arrangement can be such that the contacts are arranged on a longitudinal extension of the coupling element. Accordingly, the lower edge of the card can be used to move the slide, but there is still the possibility of connecting to the socket device. It is particularly advantageous if the longitudinal extension is formed on one side of the longitudinal center plane of the coupling element, so that a slide displacement can take place with the central region of the coupling element, which protects against canting and, moreover, the socket device can be stationed in a side region, which is advantageous for reasons of space is.
  • the coupling element has a printed circuit board, on one broad side of which the coding substrate of a key card is arranged.
  • This design has particular advantages, since a specially desired one can be selected from the large number of valid key codes of the locking device and its coding substrate can be attached to the broad side of the coupling element.
  • the key cards and the coupling element have the same dimensions in width and thickness, so that in this way one and the same coding device tailored to the corresponding dimensions are used for generating the coding. No special device for coding the coupling element is therefore necessary.
  • the coding substrate lies in a broadside recess in the printed circuit board.
  • the arrangement is then not bulky, in particular it can be provided that the surface of the coding substrate is flush with the surface of the printed circuit board.
  • At least part of the key card code is preferably formed by magnetized areas.
  • the tumblers designed as magnetic pins can be controlled with these magnetized areas.
  • Another part of the key card code is formed by a bar code. This bar code is read by the card reader, so that the corresponding data can reach the memory and be written there.
  • the bar code detected by the card reader controls the tumblers or tumblers which can or can be brought into the release position by means of a magnet coil which can be excited by the card reader. Accordingly, not only the magnetic code for the tumbler release, but also in combination therewith also the bar code is active, so that the bar code takes on a double function by realizing the feeding in of desired data in addition to the tumbler shift.
  • An advantageous design is characterized in that the slide has bearing recesses on its sliding surface resting on a perforated plate fixed to the lock housing, in which the tumblers designed as magnetic pins lie displaceably and that the holes in the perforated plate with the bearing recesses are in the basic position of the slide are aligned.
  • a ferromagnetic plate ensures that when the coupling element is not inserted, the magnetic pins are tightened in such a way that they produce a coupling between the perforated plate and the slide. If the coupling element with its magnetized areas is inserted so that the correspondingly named poles of the magnetic points and magnetic pins lie opposite one another, the magnetic pins are pushed back and the slide is released.
  • Fig. 1 shows the locking device 1 according to the invention, consisting of a lock 2 and at least one key card 3.
  • the housing of the lock 2 is provided with an insertion slot 4 into which the key card 3 is to be inserted to release the locking mechanism. If the key card 3 has a valid coding, a bolt actuation shaft is coupled with an actuation button 5 so that a bolt shift can take place.
  • Such locks 2 are operated with a multiplicity of key cards 3, the individual key cards 3 being handed over to authorized persons, so that only these persons have access to a control area or the like which is blocked off with the lock 2. It is provided that the lock 2 in the area of its slot 4 has a card reader 6, which detects at least part of the key card code 7, whereby in addition to a locking authorization check, there is the possibility of transferring key card data into a memory 7 'of a lock electronics 8 in the memory 7 'are then special information about the key number, the system number, the date and time of a lock, the execution of the locking process (whether only the key card has been inserted or whether the lock mechanism has also been moved) and values have been saved as to whether there have been malfunctions. It is possible to store a desired number of closings previously carried out, the memory content always being updated by overwriting the oldest data with the youngest.
  • a connection between the lock 2 and a corresponding logging device must be created.
  • This logging device is preferably designed as a mobile printer.
  • a coupling element 9 which is inserted into the slot 4 of the lock 2, a data transmission path can be created between the lock electronics 8 and the printer used, so that the desired information can be listed by the printer.
  • FIG. 2 shows — in a broken-open representation — the structure of the key card 3, which is composed essentially of two components.
  • One component is the carrier material 10 of the key card 3, which is preferably made of a suitable plastic.
  • the second component is formed by a coding substrate 11, which is applied to the carrier material 10 and enables the key card 3 to be individualized.
  • a barium ferrite coating 12 is applied to the card-shaped carrier material 10 of the key card 3, which is made of plastic and which can be magnetized by means of a device, not shown, so that magnetic regions 13 with north and south poles can be formed. These magnetized areas 13 have permanent magnetism and form part of the key card code 7.
  • a bar code 14 which preferably consists of three tracks 15, 16 and 17 running parallel to one another.
  • the bar code 14 has bars of uniform width which, viewed in the longitudinal direction of the track, are at a uniform distance from one another, provided that there are no spaces 18 between them.
  • the bar code 14 is covered by a film 19 which is permeable to infrared radiation.
  • the inside surface of the film 19 is printed with the bar code 14, i.e. the bar code 14 is applied to this side of the film 19 by means of screen printing.
  • the film 19 has a black color from the outside, i.e. it is not transparent.
  • the card reader 6 of the lock 2 works by means of infrared radiation and can accordingly penetrate the film 19 for scanning the bar code 14.
  • FIG. 3 shows essential components of the castle structure.
  • the lock 2 has a lock housing 20, in which a slide 21 is guided in a longitudinally displaceable manner and rests with its sliding surface 23 on a perforated plate 22 fixed to the lock housing.
  • the other side of the Perforated plate 22 is covered by a cover plate 24, which forms the one wall of the insertion shaft 4.
  • the second wall of the insertion shaft 4 is formed by an anchor plate 25 made of ferromagnetic material, which is pressed onto the cover plate 24 by a spring 26.
  • the slide 21 is held in the basic position (position according to FIG. 3) by means of a spiral tension spring 27.
  • the holes 28 of the perforated plate 22 are aligned with bearing recesses 29, in which tumblers 31 designed as magnetic pins 30 lie longitudinally displaceably.
  • the slide 21 has a projection 32, against which the middle area of a key card 3 or an inserted coupling element 9 inserted into the insertion slot 4 can occur.
  • At least one of the bearing recesses 29 of the slide 21 is surrounded by a magnetic coil 33.
  • the magnetic coil 33 is connected to the lock electronics 8.
  • the card reader 6 extends into the area of the insertion slot 4 and is also connected to the lock electronics 8 by means of a cable connection.
  • the magnetic pin 30 surrounded by the magnetic coil 33 is not moved by a magnetized area 13 in the release position, but is displaced due to an excitation of the magnetic coil 33. This is done by the card reader 6 querying the bar code 14 - or at least part of it - and comparing the read information with information from the memory 7 'of the lock electronics 8. If there is a match, the magnetic coil 33 is excited and the corresponding tumbler 31 is displaced. Overall, the slide 21 is thus released and can be moved into the position according to FIGS.
  • Figures 6 to 10 show the possibility of introducing a special element in the slot 4 of the lock 2, which creates an electrical connection to the lock electronics 8, whereby a mobile printer can be connected to print out a log of the memory content of the lock memory 7 ' .
  • the special element designed as a coupling element 9 is shown in detail in FIGS. 6 to 8. It consists of a strip-shaped circuit board 34, which has a plastic carrier 35 and a conductor track coating 36. The conductor track coating 36 is covered by a film 37 for electrical insulation. From Fig. 6 it can be seen that the upper edge 38 of the coupling element 9 is surmounted by a longitudinal extension 39 which is arranged on one side of the longitudinal center plane 40 is.
  • conductor tracks 41 of the conductor track coating 36 run out, as a result of which contacts 42 are formed.
  • the arrangement is preferably designed in such a way that both sides of the printed circuit board 34 are provided with a conductor track coating 36 in the region of the contacts 42, through-bores being able to be made through corresponding bores 43, whereby contacts 42 are formed on both sides of the printed circuit board 34.
  • the contacts 42 are connected via the conductor tracks 41 to a multi-core cable 45, the individual wires of which are soldered to the conductor tracks 41 in the lower side edge region 46 (FIG. 6).
  • bores 47 can be provided there for the attachment of a housing / Griffabschnit tes, in which electronics can also be accommodated if necessary.
  • the cable 45 leads to a mobile printer, not shown.
