Definitions

  • the invention relates to a spring-loaded tumbler in a rotary lock cylinder for a security lock, with a rotor pin and a housing pin, which are arranged with a socket wrench inserted into a key channel of the rotary lock cylinder to enable the rotor to rotate, and with a locking element which, when attempting to unlock the lock Housing pin follows.
  • a guard lock of this type has become known from the applicant's CH-A-669 633.
  • This has a locking pin and a compression spring in a hole in the core pin.
  • the compression spring presses with pretension on the locking pin, which in turn presses on the housing pin resting on the core pin. If the housing pin is lifted from the core pin during an unlocking attempt, the locking pin follows the housing pin essentially without delay and locks the rotor.
  • Unlocking security is understood to mean the degree of difficulty in classifying the tumblers of a locking cylinder with non-destructive means without knowledge of the locking code.
  • the locking member has a part which is preferably displaceably guided in the housing pin and which is magnetically connected to the rotor pin.
  • the magnetic connection of the displaceably guided part to the rotor pin can be separated substantially without additional force when the rotor is rotated.
  • the part that can be moved remains connected to the core pin.
  • the displaceably guided part therefore always follows the core pin without delay.
  • the displaceably guided part is a pin which is mounted in a longitudinal bore of the housing pin.
  • the pin is preferably a steel bolt which is freely displaceably mounted in the housing pin and which would have to be locked and sheared off in the event of an attempt to unlock it.
  • the rotor pin has a spring element which is supported directly or indirectly on the housing pin and which loads the rotor pin radially inwards. This spring element continuously presses the rotor pin radially inwards.
  • a particularly strong magnetic connection can be achieved if the blocking member has a permanent magnet made of an alloy which contains metals from the group of the lanthanides. This makes it possible to exert a high adhesive force even with a very small magnetic part.
  • the permanent magnetic part can thus be realized as a pin with a diameter of, for example, 0.5 mm.
  • FIG. 1 shows a section through part of a locking cylinder with a tumbler according to the invention in the basic position
  • FIG. 2 shows a section according to FIG. 1, however, with a socket wrench inserted into the key channel
  • FIG. 3 shows an illustration according to FIG. 1, the locking being shown here in a state during an unlocking attempt.
  • a rotary lock cylinder 1 which is shown here only in sections and is conventional, has a housing 2 with a longitudinal bore 27 in which a rotor 3 is mounted.
  • a key channel 22 is incorporated into the rotor 3, into which a key 23 is inserted in order to arrange a tumbler 4 is.
  • the tumbler 4 is moved and arranged radially outwards by means of a bore 29 in the key 23 in a radial bore 24 against the retroactive force of a housing spring 8.
  • FIG. 2 shows the arranged tumbler 4.
  • the rotor 3 is not locked here by the tumbler 4 and can be turned with the key 23 and a bolt of a lock, not shown here, can be actuated.
  • the locking cylinder 1 generally has several such tumblers 4.
  • the housing pin 9 is mounted in a bore 7 of a slide 6 known per se.
  • a steel pin 11 is slidably guided in a continuous longitudinal bore 10 of the housing pin 9.
  • This pin 11 adheres magnetically to a pin 16 which is inserted into a blind bore 14 of a rotor pin 12 and which is pressed into a bore 20.
  • the pin 16 is thus firmly anchored in the rotor pin 12.
  • the pin 16 is a permanent magnet and is preferably made from an alloy of rare earth metals (lanthanides).
  • the permanent magnet has a flat end face 30 at its free end, on which a likewise flat surface 31 of the pin 11 bears. In the case of the arranged tumbler 4, the surfaces 30 and 31 lie in the shear surface 27 of the locking cylinder 1.
  • the pins 11 and 16 can be easily moved laterally with respect to the arranged tumbler 4.
  • the housing pin 9 bears with a front surface 32 against a surface 13 of the pin 12 and holds it in the position shown in FIG. 1, in which the pin 12 lies with a shoulder 26 against a shoulder 25 of the bore 24.
  • a sleeve 15 is mounted, which receives the pin 16 with a continuous stepped bore 17.
  • the bore 14 receives a compression spring 19 which stretches the sleeve 15 against the housing pin 9.
  • the spring 19 has a spring force that is significantly less than that of the spring 8. The meaning of the spring 19 is explained further below.
  • the pins 11 and 16 according to FIG. 2 are arranged in such a way that they can be moved laterally against each other when the rotor 3 is rotated.
  • the tumbler 4 thus works like a normal tumbler without a locking device.
  • the pin 11 remains attached to the permanent magnetic pin 16 and remains in the blocking position shown in FIG. 3.
  • the pin 11 exceeds the shear surface 27 and would have to be sheared through to enable the rotor 3 to rotate. Since the pin 11 is freely displaceable in the bore 10, it cannot be fixed in the housing pin 9 even by tilting the rotor. To enable the lock cylinder to rotate, the rotor pin 12 would therefore also have to be raised to the position shown in FIG. 2, which is hardly possible and, in addition, the retroactive force of the spring 19 would have to be overcome.
  • the pin 11 is designed as a permanent magnet.
  • the housing pin 9 would then be made of an anti-magnetic material.
  • the pin 11 is fixedly connected to the housing pin 9 and the pin 16 is freely displaceably mounted in the rotor pin 12.

Abstract

Une serrure de sûreté comporte une gachette à ressort (4) dans un cylindre de verrou tournant (1), laquelle comprend une broche de rotor (12) et une broche de corps (2) disposées de sorte que le rotor (3) peut être libéré pour tourner par une clé introduite dans une entrée de serrure (22) du cylindre (1). Un élément de blocage (5), lequel suit la broche de corps (9) lors d'une tentative d'ouverture, est pourvu d'une pièce (11) guidée pour se déplacer dans la broche de corps (9) et reliée magnétiquement avec la broche de rotor (12).
