Definitions

  • the invention relates to a locking device according to the preamble of claim 1.
  • Locking systems in larger objects such as blocks of flats, schools, administrative buildings or industrial companies are usually arranged in a security hierarchy, so that only individual locks can be opened with certain keys, while keys of a higher hierarchical level fit into other locks and a general key of the highest hierarchical level opens all of them Locks enabled.
  • keys of a higher hierarchical level fit into other locks and a general key of the highest hierarchical level opens all of them Locks enabled.
  • people who use these objects receive the key assigned to the relevant hierarchy level.
  • access control systems with card systems that work electronically are also known.
  • the authorized person pushes the card into a slot, which is then read and evaluated electronically and automatically opens the relevant door when the authorization is determined.
  • Such access control systems are very complex to install, but they have the advantage that the authorization of these cards can be deleted if individual cards are lost, so that the system can otherwise be operated without compromising security.
  • Locking devices which represent a combination of mechanical and electronic coding, offer an increase in security compared to locking systems working with purely mechanical coding, with reduced investment costs compared to access control systems with cards.
  • Such locking devices are described, for example, in a brochure by Bauer Kabaabotechnik GmbH Co. & KG.
  • the invention has for its object to improve a locking device according to the preamble of claim 1 so that the locking device is faster, easier and more economical to perform when installing or upgrading existing locking systems.
  • An important aspect of the invention is that the energy source is not arranged in the lock unit, but in the key. If the energy source of a key is then exhausted, there is still the possibility of opening the lock with another key, so it has not become completely unusable.
  • the cumbersome exchange of an independent energy source otherwise located in the lock unit or the laying of corresponding power supply lines to the lock unit is eliminated.
  • the need for space is reduced by eliminating such an energy source, so that it is possible to arrange the code evaluator with the unlocking device in the locking cylinder.
  • the unlocking device comprises an electromagnetically actuated, mechanical flip-flop.
  • a practical embodiment of the mechanical flip-flop comprises a magnet armature designed as a latch which, when tightened by an electromagnet, releases a bolt which can be displaced against the force of a spring.
  • the latch is only briefly tightened in this embodiment and the bolt, which is biased against the spring force, can then retreat and release the rotary movement of the lock cylinder insert. Once tightened, the latch can then fall off the pole pieces and return to its starting position after the opening process and removal of the key, as soon as the bolt has returned to its end position due to the spring force.
  • the spring rests stationary at one end, is supported against the bolt in the central region and carries a stop surface for the key shaft at the free end, which, when the key is inserted, has a Unlocking force exerts on the bolt.
  • the same spring is thus biased by the biasing force of the key so that the bolt experiences a force in the opening direction and can relax when the key is removed, whereby the bolt receives a force in the closing direction.
  • the trap is arranged under the vertically mounted electromagnet and is pivotally mounted about a horizontal axis.
  • the trap can move back to its starting position without additional spring force, namely exclusively under the influence of gravity, and snap in behind the bolt.
  • the unlocking device comprises an electromagnet, which via a capacitor arranged in the locking cylinder and chargeable by the energy source located in the key, if the code of Key and lock cylinder can be energized.
  • the energy supply lines are designed for one polarity through the key shaft with the locking cylinder and for the other polarity through a contact at the end of the key shaft with a central contact of the locking cylinder, preferably the stop surface on the spring.
  • the contact in the locking cylinder is very well protected against damage and dirt.
  • the spring pressure ensures reliable contact and mechanical cleaning of the contacts. Contact resistances that otherwise occur at low operating voltages Function could be impaired in this way.
  • the arrangement of the contact on the key also ensures a high short-circuit protection when carrying the key together with other keys, since practically no contact with them can take place at the end of the key.
  • the contacts at the root of the key shaft on the one hand and in the locking cylinder are formed by corresponding contacts which are in alignment with the contacts on the key when the key is in the inserted state.
  • An additional measure to improve short-circuit safety is that the key carries a sliding contact cover when inserted into the lock cylinder.
  • This contact cover normally lies over the contacts, so that when the relevant key is carried on the key ring, contact with other keys can also not lead to bridging of the corresponding contacts for the power supply lines. Furthermore, it is also possible to provide the key with a manually operated button that is looped into the power supply lines.
  • a particularly advantageous embodiment for improving the short-circuit protection and protecting the battery from undesired discharges is a solution which comprises a timer circuit in the key which only briefly releases a charging current for the charging capacitor.
  • a development of this embodiment provides that the timer circuit via a The feedback line can be connected to the code evaluator in the key and can only be initialized if the code matches.
  • the current required to actuate the unlocking device is only taken from the key-side energy source if the key is in the lock cylinder and the authorization to open the lock has been proven.
  • a practical embodiment of the code transmitter comprises a code memory, a controller circuit for code word formation and a data transmitter
  • a practical embodiment of the code evaluator comprises a data receiver, a code memory and a controller circuit for code word comparison, which is connected to a control input of the unlocking device.
  • the keys and the locking cylinders of the locking device contain partially identical components, which enable cost-effective production in mass production, and differ only in the memory contents of the code memories.
  • the Change authorizations because, for example, they specify different hierarchy levels for keys or delete the codes of individual keys for locking cylinders or record those of other keys.
  • the code evaluator additionally comprises a data transmitter arranged in a feedback line, controlled by its controller circuit, and the code transmitter comprises a data receiver connected to its controller circuit.
  • a code match signal can be transmitted to the code-side controller circuit, which serves to initialize the timer circuit.
  • the authorization check takes place until the lock cylinder is released in dialog, which provides additional security against misuse and, at the same time, the key-side energy source is only used if there is authorization to open the lock.
  • the energy supply lines are also provided for data transmission.
  • a lock cylinder 12 is shown, which does not differ in its external design and in its dimensions from conventional mechanical lock cylinders. It can therefore be replaced with the original lock cylinder in a conventional mechanical lock.
  • While vertical locking pins can be arranged in the area on the left in the drawing, which enable conventional mechanical coding, is located in the rear part of a code evaluator 16 with an unlocking device 18.
  • This unlocking device serves to lock the rotary insert 66 of the locking cylinder 12.
  • the unlocking device 18 is shown in detail in FIG. 2. It comprises a mechanical flip-flop 26, which consists of a displaceable latch 34, a spring 32, an electromagnet 30 and a latch 28.
  • the bolt 34 is located in a longitudinal groove 62, which is located both in the housing 64 of the locking cylinder and in the rotatable part 66 and overlaps both parts in the locked state, so that a positive connection between the housing 64 of the locking cylinder 12 and the rotatable part 66 consists.
  • the spring 32 is stationary at one end on the electromagnet 30 and is supported in the central region against the bolt 34. At the free end, the spring 32 carries a stop surface 36, against which the key shaft of the key 10, which is partially shown here, presses in the inserted state. In this way, the key shaft 38 exerts an unlocking force on the bolt 34. If the key 10 is removed, the Latch 34 is pressed by the spring 32 to the left against its stop and brings about the aforementioned locking between the rotatable part 66 and the housing 64 of the locking cylinder 12.
  • the spring 32 When the key 10 is inserted, the spring 32 is compressed by the contact of the key shaft 38 with the stop surface 36 to such an extent that a force is exerted in the opposite direction, ie to the right.
  • the displacement of the bolt 34 is blocked by the latch 28, which is arranged here vertically under the electromagnet 30 and is pivotally mounted about a horizontal axis. The trap 28 thus falls back into the starting position under the force of gravity.
  • the latch 28 since it is designed as a magnet armature, is briefly attracted to the electromagnet 30 and indicates the displacement path for the bolt 34 free. After the trap 28 drops when the current pulse in the electromagnet 30 subsides, the trap 28 lies on one Leg of the bolt 34. The bolt 34 is now in the right end position and only engages in the area of the longitudinal grooves 62 located in the housing 64 of the locking cylinder 12. Thus, the positive connection between the housing 64 and the rotatable part 66 is released and the lock can be opened by turning the rotatable part by means of the key 10.
  • FIG. 2 also shows the energy supply lines 22 and 24, via which electrical energy for actuating the electromagnet 30 is conducted from the energy source arranged in the key to the code evaluator 16 and the unlocking device 18.
  • One power supply line 22 is formed by the key shaft and the housing 64 of the locking cylinder 12 and the other by a central contact 42 at the end of the key shaft 38 and the stop surface 36 and the spring 32. From there, conventional wiring lines lead to the code evaluator 16 and to the electromagnet 30 .
  • the power supply lines 22 and 24 also serve for data transmission at the same time.
  • Fig. 3 shows a plan view of a key 10 of the locking device according to the invention.
  • the key 10 has a conventional key handle 70 in which a code transmitter 14 and an energy source 20 are arranged. At 68 there is also a type plate for identification of the key number.
  • the key shaft 38 is located on the handle 70, which is designed here as a key bit with the usual mechanical coding. At the front end of the key shaft 38, the contact 42 can be seen, which forms one part of the energy supply lines 22, 24, while the other part is represented by the remaining key shaft 38.
  • the key 10 can be used in addition to the use in locking devices of the type according to the invention in conventional locks which work as part of a locking system exclusively with mechanical coding.
  • locking devices with electronic locking components also in the locking cylinder the security against misuse is increased by the additional mechanical coding.
  • FIG. 4 shows a circuit diagram of the lock cylinder 12 arranged code evaluator 16. This comprises a data receiver 52, a code memory 54 and a controller circuit 56 for code word comparison. In addition, a charging capacitor 40 is provided, which supplies the energy for the unlocking device 18.
  • the code memory 54 can contain the codes of one or more key numbers. If there is a match, a control signal is emitted on the one hand to the unlocking device 18, of which a switching transistor 72 and the magnet coil of the electromagnet 30 are shown here. In addition, a code match signal is transmitted back to the code transmitter 14 via a data transmitter 58.
  • the charging capacitor 40 is then charged via a diode 74 and the stored charge is transferred as a current pulse to the magnetic coil of the electromagnet 30 after the switching transistor 32 has been released. This is followed by the brief tightening of the latch 28 mentioned in connection with the description of FIG. 2, so that the bolt 34 is released.
  • the diode 74 in connection with the charging capacitor 40 also serves to screen the supply voltage of the electronic assemblies so that their function is not impaired by the energization of the solenoid of the electromagnet 30.
  • the code transmitter 14 comprises a code memory 46, a controller circuit 48 for code word formation and a data transmitter 50.
  • the energy source 20, a data receiver 60 and a timer circuit 44 are also provided.
  • One or more code numbers can be contained in the code memory 46 of the code transmitter 14 if the key is, for example, the authorization for several locks of a lower one Hierarchical level.
  • the stored code is transmitted from the controller circuit 48 via the data transmitter 50 to the code evaluator 16 of the locking cylinder 12. The transmission takes place here via the energy supply lines 22 and 24, the contact 42 at the end of the key shaft 38 being shown as the output.
  • the energy supply of the code transmitter 14 takes place from the energy source 20 formed by a battery via resistors 76 and 78.
  • the resistor 76 also forms a series resistor for the energy supply of the code evaluator 16.
  • a code matching signal supplied by the code evaluator 16 passes through the data receiver 60 to the controller circuit 48 and causes the controller circuit 48 to initialize the timer circuit 44. This then switches through the switching transistor 80 for a limited time and thereby bridges the series resistor 76, so that the full charging current can flow from the energy source 20 into the charging capacitor 40. After completion of the charging process, the timer circuit 44 blocks the switching transistor 80 again.
  • charging of the charging capacitor 40 does not always take place every time the key 10 comes into contact with a locking cylinder 12, rather charging is limited to the cases in which a code match has been found and energy is actually required to energize the electromagnet 30.
  • the charging capacitor 40 will also charge partially via the resistors 76 and 78 even before the switching transistor 80 is switched on. If it should be shown that this amount of charge should already be sufficient to actuate the electromagnet 30, switching of the switching transistor 80 would be unnecessary, as a result of which the key's energy source could be relieved.
  • the invention can also be implemented without such a charging capacitor if the energy source 20 provided in the key is dimensioned sufficiently strong. In the first working phase, when checking for code conformity, there is only a minimal load on the energy source 20 because of the very low current that the electronic circuits require.
  • code memories 46, 54 can of course be reprogrammed in a manner known per se with a programming device in order to change the authorizations of a key in the desired manner.
