Definitions

  • the invention relates to a tumbler according to the preamble of claim 1.
  • the generic US-A-3,869,889 discloses one Guard locking in a rotary lock cylinder, some has locking pin mounted in the housing pin.
  • the Lock pin is spring loaded and in an attempt to grip the two tumbler pins, the latter picks up Locking pin in the space between the two tumbler pins.
  • a further tumbler of this type is from the applicant's CH-A-669 633 known. This has in a hole of the core pin a locking pin and a compression spring. The Compression spring presses the locking pin with pre-tension in turn on the housing pin resting on the core pin suppressed. If you attempt to unlock the housing pin from When the core pin is lifted off, the locking pin essentially follows the housing pin without delay and locks the Rotor.
  • the invention has for its object a guard locking to create of the type mentioned, the security unlocking the takes higher security requirements into account. Under unlocked security the degree of aggravation is understood, the tumblers of a locking cylinder with aids can be classified non-destructively without knowing the locking code.
  • the part that can be moved is according to a further training the invention a pin which in a longitudinal bore of the Housing pin is stored.
  • the pen is preferably a Steel bolt, which is freely displaceable in the housing pin and which locks and shears off in the event of an attempt to unlock the door should be.
  • the rotor pin has a spring element that is indirect or is supported directly on the housing pin and that loaded the rotor pin radially inwards. This spring element continuously pushes the rotor pin radially inwards.
  • the radially guided part of the Locking device always in one thanks to the magnetic fixation Held position in which this slidably guided Part exceeds the shear line of the rotor and thus locks.
  • the rotor would only be released if if the housing pin and the rotor pin at the same time be classified.
  • a particularly strong magnetic connection can then be implemented, if the locking device a permanent magnet from a Alloy, which metals from the group of Contains lanthanides. So it is possible, even with one very small magnetic part to exert a high adhesive force.
  • the permanent magnetic part can thus be used as a pin a diameter of 0.5 mm, for example.
  • Rotary lock cylinder 1 has a housing 2 with a longitudinal bore 27, in which a rotor 3 is mounted.
  • a key channel 22 incorporated into the Arranging a tumbler 4 to introduce a key 23 is.
  • the tumbler 4 is by means of a bore 29 in the key 23 in a radial bore 24 against the retroactive force of a housing spring 8 radially outwards moved and arranged.
  • Figure 2 shows the classified Tumbler 4.
  • the rotor 3 is here through the tumbler 4 not locked and can be turned with the key 23 and operated a bolt of a lock, not shown here become.
  • the lock cylinder 1 usually has several such tumblers 4.
  • the housing pin 9 is in one Bore 7 of a slide 6 known per se mounted.
  • a steel pin 11 is slidably guided.
  • This pen 11 adheres magnetically to a pin 16 which is in a blind hole 14 of a rotor pin 12 is inserted and in a bore 20 is pressed.
  • the pin 16 is thus firmly anchored in the rotor pin 12.
  • the pin 16 is a permanent magnet and preferably from an alloy of rare Earth metals (lanthanides) manufactured.
  • the permanent magnet has at its free end a flat end face 30 which also bears a flat surface 31 of the pin 11. With the arranged tumbler 4, the surfaces 30 and 31 in the shear surface 27 of the lock cylinder 1.
  • the housing pin 9 lies against a front surface 32 a surface 13 of the pin 12 and holds it in the in Figure 1 shown position in which the pin 12 with a Shoulder 26 abuts a shoulder 25 of the bore 24.
  • a sleeve 15 is mounted in the blind bore 14, the pin 16 with a continuous stepped bore 17 receives.
  • the bore 14 receives a compression spring 19, which the sleeve 15 clamps against the housing pin 9.
  • the feather 19 has a spring force that is significantly less than that of the spring 8. The meaning of the spring 19 is further explained below.
  • the pins 11 and 16 In the authorized classification of the tumbler 4 with one Keys 23 are the pins 11 and 16 according to FIG. 2 arranged that this when turning the rotor 3 laterally can be moved against each other.
  • the tumbler 4 works here like a normal tumbler without a locking device.
  • pin 11 is designed as a permanent magnet.
  • the housing pin 9 would be then manufacture from an anti-magnetic material. A significant improvement in locking security is already given when the lock cylinder 1 at least has a tumbler 4 according to the invention.
  • Some tumblers of the lock cylinder 1 can thus be customary.
