Definitions

  • the invention relates to a locking device consisting of a lock and key, which has tumblers which can be transferred in the release position by means of the key.
  • Locking devices of this type are known. They can be formed, for example, by locking cylinders that can be locked with flat keys, or else by locking devices that work with magnetic keys.
  • the invention is therefore based on the object of creating a locking device of the type mentioned in which the number of lock combinations is increased without increasing the design of the key.
  • an emergency key is also to be created which allows the lock to be opened in emergency situations and, moreover, in systems with constantly changing users, it must be ensured that an unauthorized lock operation cannot be carried out in a simple manner.
  • improper use of the emergency key is to be made more difficult and the versatility of the locking device is to be increased.
  • At least one of the tumblers can be brought into the release position additionally or alternatively to their direct control of the basic code of the corresponding key by means of a magnetic coil which can be excited by a reading device which detects at least one supplementary code of the key.
  • the locking device according to the invention can thus be actuated by the key, which actuates a certain number of tumblers in the usual way (eg mechanically or permanently magnetically), in particular in the case of coded magnetic cards.
  • at least one tumbler of certain keys can only be brought into the release position by means of the magnetic coil, the magnetic coil being excited by the reading device, which detects the supplementary code of the key when it is inserted into the locking device.
  • the existing key coding that is to say the basic code (for example closing notches, permanently arranged magnets)
  • a supplementary coding (supplementary code)
  • Such a supplementary code which is designed as a bar code and / or as a hole pattern penetrating the key and / or as a magnetic code (in particular magnetic tape code) which can be detected by an induction reading head can not increase the size of the key.
  • the key can preferably be designed as a card.
  • the supplemental code creates a significant increase in the number of coding combinations in conjunction with the normal key code.
  • the bar code can be changed easily if it is attached to the key as a sticker.
  • the hole code can be changed using additional holes.
  • the magnetic code is changed by additional permanent magnets or, in the case of the magnetic tape code, by changing the information recorded on it.
  • the opening code of the locking device can thus be changed with every user change. It is only necessary to ensure that the reading device knows the currently valid code, which can be done, for example, by an update program, the coding of which is updated each time the user changes.
  • the arrangement could be such that the update is carried out independently by the reading device or an electronic circuit of the lock, so that complex cable connections to a central unit can be omitted.
  • the keys issued are provided with the current code by a key issuing unit.
  • the tumbler assigned to the solenoid can be brought into the release position by means of the "normal" coding of the key - ie not via the supplementary code.
  • This opens up the possibility of creating an emergency key which nevertheless allows the locking device to be opened if the reading device or the like fails. Such a failure could be caused, for example, by malfunctions or also by a power failure.
  • the reading device is designed as an optical reading device or as a reading device equipped with an induction magnetic head.
  • a further development of the invention is characterized by a housing in which there is a slide which can be displaced by means of the magnetic key if the coding is correct and which, in its displacement position, transfers the lock to the unlocking position.
  • the magnetic key can preferably be designed as a card provided with magnetic coding, which preferably carries the bar code on at least one flat side.
  • the slide has bearing recesses on its support surface resting on a perforated plate fixed to the housing, in which the tumblers designed as magnetic pins lie displaceably and that the holes of the perforated plate are aligned with the bearing recesses in the basic position of the slide.
  • the locking device having an insertion slot for the magnetic card, the flat side of which comes to lie parallel to the perforated plate when inserted.
  • part of the magnetic pins can form the basic code by position, number and polarization, while another part creates the supplementary code.
  • At least one of the bearing recesses is arranged in a magnetic pin carrier rotatably mounted on the slide and fixable in certain rotational positions.
  • the shifting of the magnetic pin carrier allows an additional variation of the coding combinations.
  • At least one of the bearing recesses is surrounded by the magnetic coil. This bearing recess then houses the tumbler, which can be controlled by the reading device when using the normal key.
  • a locking device consisting of a lock and a magnetic key with a housing in which a slide which can be moved by means of the tumblers in the release position is located and which, in its shifted position, transfers the lock to the unlocked position, one of which is a supplementary code of the key-reading device is provided which controls at least one additional tumbler releasing the slide.
  • the additional tumbler can preferably be formed by an electromagnetically displaceable tumbler pin which engages in a recess in the slide in the locked position.
  • the locking device according to the invention can be implemented particularly easily using already existing locks if a relining housing which can be attached to the lock housing and which essentially accommodates the reading device and possibly the additional guard locking is provided.
  • an already known lock can be converted into an object according to the invention with simple means if the lock housing of this lock is fastened to the relining housing, it only being necessary to ensure that the reading device essentially present in the relining housing has access to the key with its reading sensor.
  • the additional tumbler interacting with the slide is to be accommodated in a suitable manner in the lock housing and / or relining housing. This can be done, for example, by creating an access channel to the slide in which the guard locking is located.
  • At least one bearing recess is provided on the sliding side opposite the bearing surface of the slide, the magnetic pin of which cooperates in the locked position with a stop on the housing side.
  • Key cards can be provided as keys, which can be divided into normal key cards and emergency key cards.
  • the normal key card which is a subordinate card, it is provided that the coding point assigned to the electromagnetically controlled tumbler is designed as a non-magnetic zone.
  • the special tumbler surrounded by the magnetic coil cannot be actuated by means of the basic code. Rather, this actuation must be carried out by means of the supplementary code, which is read by the reading device and, via the excitation of the magnetic coil, transfers the corresponding tumbler into the release position.
  • the superordinate emergency key card is provided, which is only issued to specially authorized persons.
  • This emergency key card has a magnetic zone at its coding point assigned to the electromagnetically controlled tumbler.
  • the guard locking which can normally only be displaced by excitation of the magnetic coil can also be transferred into the release position.
  • the magnetic zone thus replaces the excitation of the magnetic coil, for example in the event that excitation of the magnetic coil is not possible due to a technical defect or a power failure.
  • the locking device according to the invention can be used in a system for the uncontrolled control of the use of locking devices, in particular lockers and / or access areas requiring authorization or the like, e.g. B. in baths, reading rooms, hotels or the like be set.
  • the locking device consists of several locks and an individual key card assigned to each user, wherein the lock and key card can be designed according to the above statements.
  • lower-level locks to be closed with the basic code of the card and higher-level locks to be closed with the additional code or the combination of basic code and additional code are provided.
  • the subordinate locks can be used on lockers, for example.
  • the actuation of the higher-level locks is reported to a detection unit.
  • This detection unit preferably detects the number of closings of the respective lock and / or the closing time. By registering this data, it is possible to control the time the user stays in the access area, which is necessary, for example, if the swimming pool is used for a limited time.
  • the recording option offers the presentation of various services, for example it is possible to activate a vending machine using the device according to the invention for dispensing a beverage. To do this, the card is inserted into a slot in the vending machine and the beverage is removed. The vending machine is provided with a higher-level lock so that the removal of the beverage is reported to the registration unit.
  • the user When leaving the access area, the user will then receive an invoice for the services they have used presents what can be done, for example, by displaying the invoice amount on a display.
  • the creation of the invoice is triggered by inserting the card into the display unit. Only when the user has thrown a corresponding amount of money into the display unit can the access area be left by means of a corresponding lock-operated barrier.
  • Such handling is not limited to the delivery of drinks, but can of course also for other services, such. B. the use of hair dryers, solariums, rent payment for umbrellas, etc. can be used.
  • the supplementary code is changed with the same basic code. It is therefore not possible for the previous user to whom a very specific supplementary code was assigned to leave an unpaid invoice amount for his subsequent user, since the subsequent user receives a new, different supplementary code.
  • the arrangement can also be such that the user has to pay a certain amount of money at the entrance of the access area before using the locking devices, from which the corresponding amount is then debited during his stay when certain services are used. When leaving the access area, the amount of money not used is paid out or an additional payment is requested.
  • the entire system can work automatically through the use of machines, so that no cashier or the like to be staffed are necessary.
  • an additional function is sought.
  • the locking device described above there is the possibility that by means of An unrecognized locking of the lock takes place, although there is no emergency situation.
  • This emergency situation is always present, for example, when the lock electronics cannot be used, e.g. due to a power supply failure.
  • the use of emergency keys should be reserved for these exceptional cases. In other words, this means that if the locking device is functional, the lock should be closed with the normal key, while in the event of a failure of the electronics, the emergency key must be used, which allows purely mechanical, permanent-magnetic locking.
  • the locking device consisting of the lock and key has a housing in which there is a slide which can be moved by means of the tumblers in the release position and which, in its displacement position, transfers the lock to the unlocked position
  • the key having a basic code designed as a magnetic code, which the tumblers shifted due to magnetic forces, as well as with a reading device that detects a supplementary code of the key, which controls at least one additional tumbler electromagnetically, and with an emergency key, especially for use with non-functional lock electrics, which emergency key in addition to the basic magnetic code on its electromagnetically controlled tumbler assigned coding point has a magnetic zone for the tumbler shift
  • a sensor responding to the lock electronics by moving the slide into its shift position f functionality monitoring circuit is provided which, in the case of functional lock electronics and emergency key operation, emits a signal indicating the present operating state when the sensor responds.
  • the sensor By means of the sensor according to the invention there is the possibility of monitoring the operating status of the locks direction. If the slide is moved using the emergency key, although the lock electronics are functional, a signal is emitted. The monitoring circuit emits this signal if it detects that the lock electronics are ready for use and that it receives the sensor signal due to the slide displacement, with the additional information being available that the slide displacement was carried out by means of the emergency key. The monitoring circuit receives the knowledge that an emergency key has been used due to the fact that a sensor signal is received, which indicates a slide displacement, although the reading device has not detected a supplementary code. The monitoring circuit is therefore also connected to the reading device.
  • the tumblers are shifted on the one hand via the magnetic forces of the basic code designed as a magnetic code and on the other hand via the magnetic effect of the magnetic zone of the emergency key, which changes in the the coding point assigned to the electromagnetically controlled tumbler is located and accordingly leads to the corresponding tumbler pin displacement without the use of an electromagnet.
  • an emergency key case of course, no signal is emitted by the monitoring circuit, since this is then not functional. The absence of the signal is desired according to the invention, since then there is proper emergency key operation which does not require any special notification.
  • the signal is an acoustic alarm signal.
  • An acoustic signal is therefore issued each time the locking system is misused, so that the misuse does not go undetected.
  • an additional bolt of the lock is moved into the closed position when the signal occurs. Accordingly, if an improper use of the emergency key is carried out, the additional bolt transferred into the closed position prevents the object secured by the locking device from opening. Only the key provided for the respective operating situation leads to its opening function, in which neither the bolt or the like nor the additional bolt of the locking device is moved into the locked position.
  • a good control possibility exists when the occurrence of the signal is written into a memory of the lock electronics.
  • the memory By querying the memory, it can subsequently be determined when and with which key an abusive operating mode was carried out.
  • other data can also be acquired, for example: B. the code of the key used, which in turn can refer to a specific person, and the day and time the key was used.
  • the locking device consisting of the lock and key is provided with a housing in which there is a slide which can be shifted by means of the tumblers in the release position and which, in its shifted position, transfers the lock to the unlocked position

  • a special key provided with a basic and command code being provided for programming the lock electronics, the command code being detected by the reading device and the use of the special key, in addition to its command, leads to the relocation of all tumblers, including the additional tumbler, and the programming commands only when one is activated by Verbrin gene of the slide in its displacement position responsive sensor are written into the memory of the lock electronics.
  • This design which, like the variant described above, includes a responsive sensor in the slide displacement position, enables a special application of the locking device due to the programming option.
  • special functions can be implemented.
  • the programming of the special key can be transmitted via special codings which are applied to the special key instead of or in addition to the "normal supplementary code".
  • the basic coding of the special key corresponds to a normal key, since even with special key operation it must be ensured that the permanent-magnet locking devices are transferred to the release position.
  • the special code then includes shifting the additional guard locking to the release position and the command program lubrication.
  • a special key with command coding can also be designed such that all the tumblers, including the additional tumbler, are controlled by permanent magnets, which corresponds to an emergency key function, and that the programming is carried out using the special code detected by the reading device.
  • the following programming is possible:
  • the locking device can e.g. can only be operated using the normal keys x, y and z, provided that the keys x, y and z are pushed into the lock one after the other within a certain time.
  • the programming can, for example, also be provided in such a way that two keys have to be used one after the other in order to enable the lock to be moved into the open position.
  • banks can use two keys to open doors that have double key security, i.e. the different keys of two different people are required to open the door.
  • This programming which can also be brought about by command key (special key) actuation, can be used, for example, if a person has lost their normal key x.
  • the "Delete” function then deletes the programming for accepting the code of the normal key x for the opening function, so that it is no longer possible to close it with the normal key x.
  • a replacement key can be inserted into the lock, the lock electronics being thereby converted to the coding of the replacement key. This means that the replacement key now has x locking function instead of the lost normal key.

It is shown that by striking the lock housing 3, the magnetic pins 21 can be displaced such that they enter their corresponding bearing recesses 19 for a short time (see position in Fig. 13). At this moment, a displacement of the slide 15 would be possible by means of a tool or the like inserted into the insertion slot, so that the lock 1 could be unlocked. In order to prevent such an unauthorized unlocking, a bearing recess 57 is provided on the slide side 29 opposite the support surface 16 of the slide 15, in which a magnetic pin 58 is slidably inserted.
  • the object according to the invention offers increased system security through an electronic system which operates in addition to the mechanical system (magnetics) and which, by reading an optical code, brings about a locking or unlocking function.
  • the optical code can be applied to the key (also temporarily) by printing or stickers.
  • Such a modified key offers a higher security standard, especially in areas with access control.
  • the key of the locking device according to the invention designed as a card, has magnetic zones distributed over its flat side at different points, which interact with the tumblers. It is possible according to one embodiment that these zones form the basic code. Furthermore, one or more of these zones can be used for the emergency key function described above.
  • the complement tion code of the key according to the invention is formed by a bar code applied on the flat side and / or holes penetrating the card and / or a magnetic tape applied or embedded on the flat side of the card. It is also possible that the supplementary code comprises one or more of the magnetic zones described above. According to a special exemplary embodiment, the basic code can also be formed by part of the magnetic zones and the supplementary code by another part of the magnetic zones.
  • the magnetic zones can differ with regard to their polarity (north pole or south pole).
  • the magnetic pins of the tumblers must be designed accordingly.
  • the holes penetrating the key card, which in the corresponding key version are arranged at various locations over the flat side of the card, are detected by suitable sensors of the reading device.
  • the reading - as with all other coding types described above - can be subdivided into a clock track and an information track.
  • the lock 1 is provided with a lock housing 3, which is placed on a relining housing 5 with its bottom region.
  • the lock housing 3 is provided with a rotary knob 6, with the aid of which a latch or a bolt, not shown, can be withdrawn if the lock 1 is in the unlocked position.
  • the embodiment basically corresponds to the lock structure already described. Here again the most important:
  • the lock housing 3 is provided with an insertion slot 9 into which a key 10 can be inserted.
  • the key 10 is as with magne table coding provided card 11 which carries a bar coding 13 on its flat side 12.
  • a slide 15 is mounted, which is plate-shaped and on its support surface 16, a perforated plate 17 rests.
  • the holes 18 of the perforated plate 17 are aligned with corresponding bearing recesses 19 of the slide 15, which emanate from the support surface 16 and are designed as blind bores.
  • Tumblers 20, which are designed as magnetic pins 21, are located in the bearing recesses 19. The dimensions of the bearing recesses 19 are chosen such that the magnetic pins 21 can be displaced perpendicular to the bearing surface 16.
  • a tension spring 25 is fixed with one end 26 on the housing side and engages with its other end 27 on a projection 28 of the slide 15. Furthermore, the slide 15 forms a run-up slope 30 on its slide side 29 opposite the support surface, which acts together with a control plate 31.
  • the control plate 31 lies with its fork-shaped end 32 on a shoulder 33 of a longitudinally displaceable coupling sleeve 34 which is biased in the direction of arrow 36 by means of a spiral compression spring 35.
  • the rotary knob 6 engages with its axis 37 in the interior of the lock housing 3 and has a gear 38 on it in a rotationally fixed manner. The toothing of the gear 38 is adapted to an internal toothing of the coupling sleeve 34.
  • a square 41 is rotatably supported by means of a bearing bush 40 and carries a gearwheel 42 at the end.
  • the square 41 cooperates with a lever mechanism which is provided for withdrawing a latch or a latch, not shown.
  • one of the bearing recesses 19 is surrounded by a magnetic coil 43, which lies in a corresponding recess in the slide 15.
  • the relining housing 5 adjoins the bottom 39 of the lock housing 3, in which an optical reading device 44 and an electronic circuit (not shown in more detail) are accommodated.
  • the relining housing 5 can also accommodate a current source for supplying the electronic circuit and the reading device 44. Alternatively, however, energy can also be supplied via a mains cable, possibly with the interposition of a transformer and a rectifier.
  • Fig. 15 shows the lock 1 in its unlocked position, which can be brought about by inserting the card 11 into the insertion slot 9 with the correct coding combination of the card 11.
  • the card 11 is pushed between the guide plate 22 and the anchor plate 23, the insertion being very easy due to the corresponding bends 45 of these elements.
  • the magnetic pins 21 engage in the corresponding holes 18 in the perforated plate 17 and rest with their end faces on the guide plate 22.
  • This position of the magnetic pins 21 is brought about by the armature plate 23, which, in contrast to the other components, consists of ferromagnetic material.
  • the anchor plate 23 thus attracts the magnetic pins 21, as a result of which they assume the position described. In this position, the slide 15 cannot be moved from its basic position shown in FIG. 15, since the engagement of the magnetic pins 21 in the perforated plate 17 fixed to the housing prevents this.
  • the magnetic pins 21 lie completely in their associated bearing recesses 19 and thus no longer form fit to the perforated plate 17. This comes about because the magnetic coding on the card acts on the magnetic pins 21 in such a way that they are pushed back into the bearing recesses 19 by facing poles of the same name.
  • the anchor plate 23 can deflect due to the spring 24.
  • the slider 15 can be moved into the position shown in FIG acts on the control plate 31 in such a way that its end 32 displaces the coupling sleeve 34 against the direction of the arrow 36, as a result of which the internal toothing of the coupling sleeve 34 comes into engagement with the gear 38.
  • the rotary knob 6 is rotatably coupled to the square 41, so that the lock 1 assumes its unlocking position and actuation of the latch or bolt is possible.
  • the arrangement is such that the magnetic pins 21 not surrounded by the magnetic coil 43 are brought into the release position by means of the basic code of the card 11.
  • the magnetic pin 21 surrounded by the magnetic coil 43 comes into the release position by excitation of the magnetic coil 43.
  • the bar coding 13 is provided on the card 11, as described above, which is optically scanned by a sensor 48 when the card 11 is inserted into the insertion slot 9.
  • the sensor 48 is connected to the reading device 44 via a line 49, as a result of which the read information reaches the electronic circuit which compares the read coding with the stored opening code of the lock 1. If there is a match, the magnetic coil 43 is activated, as a result of which the corresponding magnetic pin 21 is transferred to the release position according to FIG. 16.
  • a plurality of magnetic pins 21 are surrounded with corresponding magnetic coils 43.
  • this emergency key which is also designed as a special card 11, is provided at its location opposite the magnetic pin 21 provided with magnetic coil 43 with a magnetic coding, which displaces the pin 21 in the release position causes. Should the displacement of the magnetic pin 21 due to a technical defect-e.g. Power failure is not possible with the help of the solenoid 43, this can also be done with the help of the previously described emergency key.
  • At least one of the bearing recesses 19 can be rotated on one of the slides 15 mounted magnetic pin carrier 50 which can be fixed in certain rotational positions.
  • This magnetic pin carrier can be rotated by means of a special tool through openings in the lock housing 3, whereby the positions of the bearing recesses 19 can be changed. In this way, the lock 1 can be reprogrammed very quickly.
  • FIG. 19 shows a further exemplary embodiment of the locking device according to the invention, which differs from the previously illustrated exemplary embodiment in that there is no magnetic coil 43 on the slide 15.
  • a channel 51 is formed which extends as far as the slide side 29 of the slide 15.
  • a tumbler 52 is arranged in this channel, which can be designed as a tumbler pin 53.
  • the tumbler pin 53 can be displaced by means of an electromagnetic device (not shown), it entering a recess 54 in the blocking position on the slide side 29 of the slide 15.
  • the slide 15 interacts with a sensor 80.
  • the sensor 80 is preferably designed as an electrical switch 81.
  • it can be implemented as a microswitch 82, which has a switch sensor 83 that is pivotally mounted.
  • the sensor 80 is connected to the lock electronics via a cable connection (not shown), which, as described above, is located in the relining housing 5.
  • the lock electronics are not shown in the figures for reasons of simplification.
  • the microswitch 82 is positioned such that when the slide 15 is not displaced, that is, in the locked position of the lock, there is a free space between the end of the slide 15 facing the microswitch 82 and the switching sensor 83 of the microswitch 82. However, if the slide is moved into its displacement position according to FIG. 16, the slide end of the slide 15 comes into contact the switching sensor 83, whereby the microswitch 82 changes its switching state.
  • FIGS. 17 and 18 it is also possible to arrange the microswitch 82 laterally offset with respect to the longitudinal axis of the slide, the switch sensor 83 of the microswitch 82 not being acted upon in the slide position according to FIG. 17.
  • FIG. 18 there is the shift position of the slide 15, in which the switching sensor 83 is acted on, so that there is a change in the switching state of the microswitch 82.
  • the microswitch 82 can interact with the slide side surface, as in FIGS. 15 and 16, or it can, as in the figures 21 and 22 - a position of the microswitch 82 provided on the side of the slide 15 may be present.
  • microswitch assumes a different switching state when the slide is not displaced than when the slide 15 is moved into its displacement position.
  • the microswitch 82 can perform the following function: If the slide 15 is displaced by means of the "normal key" (card 11), the microswitch 82 is actuated in the displacement position of the slide 15. This actuation is registered by the lock electronics, not shown. Furthermore, the lock electronics receive the information via the reading device 44 that a normal key is used, because this has the supplementary code 13, which is preferably designed as a bar code. If an emergency key is used, the bar code is omitted because the corresponding magnetic pin 21 is not displaced by means of the magnetic coil 43, but is carried out by a corresponding magnetic zone of the emergency key. The absence of the bar code thus signals to the lock electronics that an emergency key is inserted into lock 1.
  • the lock electronics are informed via a special identifier of the supplementary code that a normal card is used. If the supplementary code does not have this special identifier, for example in the case of an emergency key, it is registered that there is an emergency key operation. 16, the microswitch 82 then responds, as a result of which a monitoring circuit belonging to the lock electronics receives a signal when the lock electronics are intact. This monitoring circuit simultaneously checks the functionality of the lock electronics, in particular whether a supply voltage is available. If an emergency key operation is carried out even though the monitoring circuit registers a functional lock electronics, a signal is emitted by the monitoring circuit that indicates this operating state.
  • the signal can be an acoustic alarm signal; however, it is also possible for the signal to transfer an additional bolt of the lock into the closed position, so that it is not possible to open the object locked with the lock. In addition, it can be provided that the occurrence of the signal is written into a memory of the lock electronics.
  • the microswitch 82 serves, in addition to its previously described mode of operation or alternatively, to take over program commands, which are detected by the reading device 44, into a memory of the lock electronics.
  • the programming of the lock electronics requires the use of a special key which, in addition to its basic code for shifting the tumbler pins 21, has a special coding due to its magnetic effect, which is designed in particular as a bar code.
  • a hole pattern can also be present on the card 11, which is detected by the optical reading device 44 by means of the sensor 48.
  • the additional tumbler it is not necessary for the additional tumbler to be shifted electromagnetically by means of the bar code, rather it can also be provided that the additional tumbler pin is shifted by means of a corresponding magnetic coding point on the card 11. It is then basically an emergency key that is used for reprogramming work.
