Definitions

  • the invention relates to an electromechanical locking device consisting of a cylinder lock with a device for transmitting information signals between the lock and key, a stator housing with a rotatable rotor in this housing and a locking device for preventing rotary movements of the rotor in the stator housing and a key. It is known to additionally combine cylinder locks with mechanically coded tumblers with an electromagnetic locking device, and thereby to increase the security of the locking device. In the case of bank and vault devices in particular, the electromagnetic locks act directly on the locking bolts, whereby they can mostly be actuated by an electrical or electronic control arranged independently of the mechanical key. Such systems are complex and require a relatively large amount of installation space.
  • Such a locking device is known from German Offenlegungsschrift No. 3 205 586.
  • the key carries information in the form of magnetic codes.
  • a corresponding reading device is arranged on the cylinder lock, which reads from the Key impulses given code impulses and forwarded to a recognition device.
  • This electronic detection device is connected to an electromagnetic actuation device, which can connect the rotor to the bolt actuation element in a rotationally locking manner via a driver pin.
  • This bolt actuator is arranged at right angles to the lock axis and protrudes from the lock cylinder. Stable and relatively strong magnets are required to generate the necessary forces and movement lengths of the driver pin, which means that the external dimensions of the cylinder lock become significantly larger than those of the locks normally used.
  • the electromagnet can be excited by an electrical control and that locking part sitting at the end of the armature can be brought into a position in which the link ring is released for a rotary movement.
  • the solution shown here requires an extension of the cylinder lock in the axial direction, which is undesirable in many cases.
  • the design of double cylinder locks in which two mechanical cylinders are combined with one another in the axial direction is only possible with considerable effort.
  • the axial dimensions of the lock must be changed compared to the known mechanical cylinder locks, which in turn leads to difficulties when replacing locks in existing doors and the like.
  • the locking device has a trigger bolt directed radially to the rotor axis and a locking bolt arranged parallel to this trigger bolt, also oriented approximately at right angles to the rotor axis, and one end face of the trigger bolt rests on the sliding surface of a tumbler pin positioned by the key in the rotor, the trigger bolt engages in the locking bolt via a driver, approximately at right angles to the release and locking bolts and in the areas facing away from the rotor, an electrical switching element consisting of a magnet armature with an electric coil is arranged, and the magnet armature has at least one locking device in which the locking bolt engages.
  • This inventive arrangement makes it possible to arrange the magnet armature with the electrocoil parallel to the cylinder lock axis, and thereby keeping the outer dimensions of the lock small.
  • the release and locking bolts arranged at right angles to the lock axis are operatively connected to the magnetic armature.
  • the release pin does not engage the rotor directly, but in turn interacts with a tumbler pin, which is brought into the correct position by the key inserted in the lock. Only if the mechanical coding on the key matches this release bolt can the locking bolt be released by the magnet armature, and thus the rotary movement of the rotor in the stator housing can be released.
  • This arrangement enables additional security against unauthorized intervention in the locking device, which is very important in the case of combined electromechanical locks.
  • the arrangement made also effectively prevents unauthorized intervention in the locking device by means acting on the lock from the outside. Furthermore, the space in the direction of the longitudinal axis of the cylinder lock is not claimed by the locking device, as a result of which the known mechanical rotor / stator arrangements can be used and double cylinder locks can also be combined in the known manner.
  • the operative connection between the key / lock rotor and the lock / bolt is also established in the known manner, and no additional measures are required to ensure its security and effectiveness.
  • the magnetic armature is controlled via the electrocoil by an external control or an electronic device integrated in the lock. It is obvious to the person skilled in the art that equivalent solutions are possible in which the magnet armature is extended or retracted by the magnet, or is pushed or pulled by the magnetic force.
  • a preferred embodiment of the invention is characterized in that the release pin is fork-shaped at one end, the two legs of the fork-shaped part delimit a gap, and the magnet armature is guided in this gap.
  • This arrangement enables a very compact design, the magnet armature being as small as possible Distance to the lock axis is arranged.
  • a further improvement in the construction can be achieved in that the legs extend beyond the magnet armature, form a second intermediate space, and a compression spring is arranged in this intermediate space in such a way that it presses the release bolt in the direction of the rotor.
  • a further preferred embodiment of the invention consists in that a resilient return element acting in the direction of movement of the armature is arranged on the magnet armature.
  • This return element causes the armature and the release bolt to be returned to the locked position.
  • the resilient restoring element is designed like a lever and is provided with a fulcrum, one lever arm of the element rests on a driver of the release bolt and the other lever arm of the element rests on a driver on the magnet armature.
  • This arrangement means that the release pin and the magnet armature, despite moving at right angles to one another, are inevitably connected to one another.
  • the restoring element is used in particular to return the magnet armature to its starting position when the magnet coil is de-energized.
  • the locking pin has a driver shoulder, a compression spring rests on the end face of the locking pin directed against the rotor, and the driver of the trigger pin on the driver shoulder.
  • This arrangement ensures a play-free guidance of the locking bolt, which is always in operative connection with the release bolt. Since the two bolts are arranged in parallel next to each other, it is possible to bring the release bolt into operative connection with a tumbler pin in the rotor.
  • the locking pin acts as a rotor lock in that an annular groove is arranged on the outer jacket of the rotor, this groove lies in the axis of the locking pin and extends on both sides of the normal position of the locking pin over a maximum of 90 ° of the circumference of the rotor.
  • the rotor can be rotated by a certain amount when the mechanical tumblers between the lock and key match, in order to ensure the reading process between the lock and key. There is also enough time to withdraw the locking pin from the rotor before it is clamped by the groove wall, thereby requiring a short backward movement to release the locking pin driven by a spring.
  • a further improvement in the possibilities of engagement of the locking bolt in the magnet armature can be achieved in that the locking device on the magnet armature is formed by a depression and the lower end of the locking bolt is shaped corresponding to this depression.
  • a preferred embodiment of the invention further consists in that a groove with a pin is formed on the magnet armature in the switching direction in front of the recess and a shoulder is present on the lower end face of the locking bolt, which cooperates with the pin.
  • This groove forms only a slight depression on the jacket of the magnet armature.
  • the interaction between the shoulder on the end face of the locking bolt and the pin on the magnet armature holds the magnet armature in its starting position. It is therefore not possible to bring the magnetic armature into its switching position by vibrating or other external influences on the lock and thereby withdrawing the locking pin from the rotor. This is only possible if the electromagnet is activated and the magnet armature is attracted by direct force in the direction of the lock axis.
  • the shoulder on the end face of the locking bolt jumps over the pin of the groove on the magnet armature and snaps into the recess of the magnet armature, which acts as a lock, a.
  • a further increase in the security of the locking device can be achieved in that a microswitch is installed in the electrical supply line to the electrocoil and this microswitch has a switching pin as the switching element, the end of which protrudes into the key channel on the rotor.
  • the microswitch comprises a membrane keyboard and this is integrated in the circuit board. In addition to the correct actuation of the release pin via the associated tumbler pin, the microswitch must also be actuated by the key to release the lock. Otherwise the electrical control device remains without power and the locking device is not released.
  • a membrane keyboard such as is used for example in control consoles, enables a further reduction in the structural dimensions and the integration of the switch in the rotor / stator area of a known cylinder lock. Since only one switching element is required, a single membrane key can be integrated into the circuit board, which is built into the stator housing of the lock and carries the required electronic components. All essential electronic components can be directly connected to each other on the circuit board.
  • the electromechanical locking device according to the invention has very small dimensions without restricting the desired high security standard of such locking devices. Despite the small dimensions, it has additional security features, which represent significant improvements to the known locking devices.
  • the cylinder lock 1 shown in Figure 1 contains both mechanical and electronic codes with corresponding tumblers.
  • a key 2 is inserted into the cylinder lock 1 and comprises a key bit 8, a contact area 7 and a cover 9. Grooves 46, 47 are arranged on the broad sides of the key bit 8, which cooperate with the mechanical tumblers, not shown. These tumblers, not shown, are mounted in a rotor 5, which in turn is rotatable in a stator 3.
  • a key channel 48 is also arranged in the rotor 5, in which the key bit 8 is guided.
  • An additional stator housing 4 is provided around the stator 3, which accommodates the locking device 6 and the contact device 51 with the corresponding electrical and electronic connections and components.
  • the entire cylinder lock 1 is surrounded by an outer jacket 25.
  • Electronic elements such as data storage devices, are arranged in the cover 9 of the key 2 and are connected to contact points 54 in the contact area 7 of the key 2. These contact points 54 are located on the narrow sides of the key 2 and interact with grinding springs 53.
  • the loop springs 53 are fastened to a printed circuit board 52 and stand over electrical conductors with electronic elements 55 which are on the printed circuit board 52 and / or are arranged externally in connection.
  • a membrane key 57 is integrated into the printed circuit board 52 and is part of a microswitch 56. This microswitch 56 projects into the key channel 48 and has resilient elements (not shown) in its interior. The microswitch 56 can be actuated directly through the narrow side of the key bit 8 or, as shown in FIG.
  • the microswitch 56 acts on the membrane key 57 and switches on the circuit for electronic coding or decoding.
  • the microswitch 56 ensures that the circuit is interrupted.
  • the mechanical tumblers are in the open position and the mechanical interlocks release the rotary movement of the rotor 5 in the stator 3. Since the key 2 is fully inserted in this position, the slide springs 53 are in contact with the corresponding contact points 54 on the contact area 7 of the key 2. Information or data can thus be transferred from the key 2 to the cylinder lock 1 or vice versa via the contact device 51 be transmitted.
  • the electronic elements 55 on the printed circuit board 52 and possibly further electronic elements which are assigned to the cylinder lock 1 check the correctness of the information transmitted and determine whether the key 2 inserted into the cylinder lock 1 is authorized to access. If the transmitted information is correct and matches the lock codes, the locking device 6 is released.
  • the locking device 6 consists of a release pin 13 and a tumbler pin 15, a locking pin 14, a magnet armature 12 and an electric coil 11.
  • the release pin 13 is arranged in the same axis as the tumbler pin 15 and is in an approximately rectangular position to the axis 10 of the lock 1.
  • the interaction between the tumbler pin 15, the release pin 13 and the armature 12 can be seen in particular in Figure 2.
  • the tumbler pin 15 is located in a bore on the rotor 5 and engages with its tip 44 in an edge bore 45 on the narrow side of the key bit 8. At the other end of the tumbler pin 15 there is a sliding surface 43 which, when the tumbler pin 15 is correctly positioned, is congruent with the lateral surface of the rotor 5.
  • the trigger bolt 13 has a driver 16 in its central region and a fork-shaped part 18 in the lower region.
  • the fork-shaped part 18 includes an intermediate space 19 in which the armature 12 is guided.
  • a second space 20 is arranged, in which a compression spring 21 is guided. This compression spring 21 pushes the release pin 13, and thus the tumbler pin 15, in the direction of the rotor 5, or the lock axis 10.
  • a driver shoulder 39 of the locking pin 14 lies on the driver 16 of the release pin 13 on the upper surface.
  • the locking pin 14 is mounted in the stator 3 and engages with its end in an annular groove 38 on the rotor 5.
  • This annular groove 38 extends only over a portion of the circumference of the rotor 5 and thus enables a partial rotary movement of the rotor 5 even when the locking pin 14 engages in the groove 38.
  • a compression spring 42 is arranged between the driving shoulder 39 and the stator 3 and pushes the locking pin 14 away from the rotor 5.
  • the lower end 40 of the locking pin 14 is tapered and has a shoulder 41 on the end face. This shoulder 41 interacts with a pin 36 on the magnet armature 12.
  • the magnet armature 12 has a front part 31 and a rear part 32.
  • the front part 31 is mounted in the core bore 50 of the electric coil 11 and the rear part 32 in a bore 49 in the stator housing 4.
  • a locking device in the form of a depression 34.
  • a groove 35 adjoins this depression 34 in the direction towards the front part 31 of the magnet armature 12, the pin 36 being formed between the groove 35 and the depression 34 .
  • This pin 36 has an inclined surface 37, the inclination of which is selected such that the force of the electrocoil is sufficient to push the shoulder 41 on the locking pin 14 over this inclined surface 37 or the pin 36.
  • the magnet armature 12 also has a driver 30, in which, as shown in FIG. 1, a lever arm 29 of a restoring element 26 engages.
  • This return element 26 is mounted on the pivot point 27 and has a second lever arm 28 which rests on the driver 16 of the release pin 13.
  • the two lever arms 28 and 29 are resilient, so that there is an elastic operative connection between the magnet armature 12 and the release pin 13.
  • there are parallel side surfaces 33 which are guided in the area of the intermediate space 19 on the release bolt 13 by its fork-shaped part 18.
  • the release pin 13 is pushed by the spring 21 up to an upper stop in the direction of the rotor 5.
  • the driver 16 engages with its upper surface in the locking pin 14 in that the lower surface of the driver shoulder 39 of the locking pin 14 rests on the driver 16 of the release pin 14. This will lock the bolt 14 engages against the force of the spring 42 in the groove 38 on the rotor 5 and locks it against complete rotation.
  • the release pin 13 presses the lever arm 28 of the restoring element 26 resting on the driver 16 and pushes the magnetic armature 12 into the bore 49 as far as it will go via the second lever arm 29. The locking device is thus in the normal starting position.
  • the magnet armature 12 initially blocks the further movement of the locking pin 14. The rotor can thus only be rotated to the extent that a corresponding groove 38 is arranged on the circumference. If the electronic coding of the key 2 does not match the lock 1, the rotor 5 cannot be rotated completely even if the mechanical tumblers match, and thus the lock cannot be opened. If the electronic coding of the key 2 matches that of the cylinder lock 1, the electronic control 11 is activated by the electronic control and the magnet armature 12 is drawn into the core bore 50 during the rotary movement of the rotor 5 with the aid of the key 2 in the region of the ring groove 38 .
  • the shoulder 41 on the locking pin 14 jumps over the pin 36 and the lower end 40 engages in the recess 34. Since the spring 42 presses the locking pin 14 against the magnet armature 12, the power supply to the electrocoil 11 can be interrupted immediately, as a result of which the power consumption of this device is extremely low. If the key 2 is removed again from the cylinder lock 1, the microswitch 56 also interrupts the control current to the other electrical and electronic components, which leads to a significantly increased electrical safety and service life of the power sources.
