Definitions

  • the invention relates to a lock cylinder with a rotatable core in a housing and with an electromagnetically activatable locking mechanism for selectively blocking or releasing the movement of the core.
  • lock cylinders are often used in today's locking systems and are known for example from DE 199 01 838 A1.
  • a locking bolt is slidably disposed in a bore of the housing and is biased by a spring element in the direction of the core.
  • the core has pockets for receiving the locking bolt.
  • an armature connected to the locking bolt is pressed against an electromagnet of the electromagnetically activatable locking mechanism.
  • the electromagnet is energized and holds the armature.
  • the locking bar is held within the housing, and the core can be rotated relative to the housing.
  • the locking mechanism In the absence of locking authorization, the locking mechanism is not energized and the locking bar passes through the force of the spring element upon rotation of the core in one of the pockets of the core and blocks its further movement.
  • the solenoid may possibly be magnetized such that the locking bar is retained within the housing and releases the movement of the core.
  • the invention is based on the problem, the lock cylinder of the type mentioned in such a way that its unlocking is reliably prevented even in the presence of a strong magnetic field.
  • a rocker arm is pivotally mounted and penetrates into the respective opposing component in a groove that the groove has at least one facing the next end of the core locking pocket, that the rocker arm of a spring force or gravity is biased away from the lock pocket and that the rocker arm is made of a magnetizable material.
  • the use of a strong magnetic field causes the rocker arm is pulled against the spring force or gravity in the lock pocket.
  • the rocker located in the lock pocket blocks the further movement of the core relative to the housing.
  • the locking cylinder according to the invention can thus not unlock by the use of a strong magnetic field.
  • a malfunction of the rocker arm caused by the rotation of the core can be easily avoided according to an advantageous development of the invention, when the rocker arm is mounted in the housing and the groove is arranged circumferentially in the core.
  • a hooking of the rocker arm to the projection can be according to another advantageous embodiment of the invention simply prevent when connecting to the projection ramps.
  • the rocker arm is reliably held in its position according to another advantageous embodiment of the invention, when the rocker arm is biased by a trained as a compression spring or torsion spring element.
  • the rocker arm In a magnetic field sufficient for magnetizing the locking mechanism, the rocker arm is reliably pulled into the locking pocket when the rocker arm tapers conically at its end facing away from the groove and engages the locking mechanism with a cylindrical portion and when the spring element engages the tapered end in the direction of Biases locking mechanism.
  • the transition of the conically tapered portion to the cylindrical portion thus forms the bearing about which the rocker arm can pivot without an applied external magnetic field.
  • the rocker arm Under the action of the external magnetic field, the rocker arm is attracted to the lock mechanism and enters the lock pocket as the core rotates.
  • the assembly of the lock cylinder according to the invention is particularly simple if the tapered end having rocker arm is arranged in a made of non-magnetizable material sleeve when the socket has a conical recess for the rocker arm and a further recess for the spring element.
  • the introduction of an external magnetic field in the cup-shaped locking mechanism leads to magnetic poles on the end faces of the locking mechanism.
  • the rocker arm is reliably attracted according to another advantageous embodiment of the invention by the magnetic poles generated by the external magnetic field when the rocker arm has a locking position on a core facing the end face of the cup-shaped locking mechanism resting leg.
  • Figure 1 shows schematically a lock cylinder with a rotatable in a housing 1 core 2.
  • the lock cylinder has an electromagnetically activatable locking mechanism 3 with an axially displaceable in the housing 1 and biased by a spring element 4 in the direction of the core 2 locking latch 5.
  • the locking mechanism 3 an electromagnet 6, which is able to hold the locking bolt 5 in a depressed position in the housing 1.
  • the locking bolt 5 is partially in a recess 7 of the core 2 and thus blocks the movement of the core 2 relative to the housing 1.
  • the locking bolt 5 can be pressed into the housing 1, for example, via a key 9 shown in FIG. 4, inserted into a closing channel 8 of the core 2.
  • the electromagnet 6 holds the locking bolt 5 in a completely located in the housing 1 position and thus allows the rotation of the core 2 relative to the housing 1.
  • the lock cylinder and the function of the locking mechanism 3 are described in detail in DE 199 01 838 A1, so that the disclosure of the function of the components of the lock cylinder is expressly made to this document.
  • the rocker arm 10 On the locking mechanism 3 is a made of a magnetizable material toggle lever 10 with a cylindrical portion 11 at.
  • the rocker arm 10 has a conically tapered end 12.
  • the conically tapering end 12 is supported by a ball 14 biased by a spring element 13.
  • the rocker arm 10 has a bearing at the transition of the tapered end 12 to the cylindrical portion 11.
  • the other end of the rocker arm 10 penetrates into a circumferential groove 15 of the core. Due to the bias of the rocker arm 10 via the spring element 13, the projecting into the core 2 end is biased against a wall of the groove 15.
  • the rocker arm 10 and the spring element 13 are each arranged in recesses 16, 17 of a press-fitted into the housing 1 bushing 18.
  • Figure 2 shows the lock cylinder of Figure 1 in a sectional view along the line II - II of Figure 1.
  • Figure 3 illustrates a portion of the groove 15 in the region of the penetrating into the core 2 end of the rocker arm 10. It can be seen here that the groove 15 has locking pockets 19 and a projection 20 protruding into the height of the locking pockets 19. Ramps 21 adjoin the projection 20. Since the protruding into the core 2 end of the rocker arm 10 is biased by the force of the spring element 13 shown in Figure 1 against the projection 20 and thus away from the locking pockets 19, the projecting into the core 2 end of the rocker arm 10 in a normal operation with the authorized to close the key 9 of Figure 4 in the groove 15. Each time the core 2 is rotated by means of the key 9 authorized to close, the rocker arm 10 is slightly deflected.
  • Figure 4 shows the lock cylinder of Figure 1 when closing with the authorized key to close the key 9 after a slight rotation of the core 2, in which the protruding into the core 2 end of the rocker arm 10 is located at the height of the locking pocket 19. It can be seen that the locking bar 5 is held by the electromagnet 6 of the locking mechanism 3 in a position located outside of the core 2. The rocker arm 10 is deflected by the force of the spring element 13 and slides along the groove 15. Thus, the protruding into the core 2 end of the rocker arm 10 is outside the locking pocket 19. The core 2 can be rotated relative to the housing 1.
  • FIG. 5 shows the lock cylinder from FIG. 1 during an unlocking attempt with a strong magnet 22 after the initial rotation of the core 2 described in connection with FIG. 4. It is assumed that the magnetic field of the magnet 22 is so strong that the locking bolt 5 leaves the recess 7 2 core out against the electromagnet 6 of the locking mechanism 3 is pulled. By the magnetic field but also the rocker arm 10 is pulled against the force of the spring element 13 against the electromagnet 6 of the locking mechanism 3. However, this results in that the protruding into the core 2 end of the rocker arm 10 is held in the locking pocket 19 and thus prevents the movement of the core 2 relative to the housing 1.
  • Figure 5 shows another embodiment of the lock cylinder according to the invention in the basic position, which differs from the embodiment of Figures 1 to 4 only in that a rocker arm 23 is angled and rests with legs 24 on the front side of the electromagnet 6 of the locking mechanism 3.
  • a trained as a leg spring spring element 25 biases the rocker arm 23 in a clockwise direction.
  • the rocker arm 23 is deflected by the groove 15 in the core 2.
  • the legs 24 of the rocker arm 23 are attracted by the electromagnet 6 of the locking mechanism 3 against the force of the spring element 25 and pressed into the locking pockets 19 shown in FIG.
