Definitions

  • the invention relates to a locking cylinder and or or flat key for the locking cylinder with a rotatable in a bore of a cylinder housing with a cylinder core key channel and with core and housing pins, which as tumblers of notches or serrations on the key face of the flat key from a rotation of the cylinder core blocking blocking position can be displaced into a release position, the part of at least one core pin projecting into the key channel, in particular the core pin initially lying at the opening of the key channel, having an engagement connection on its lateral surface with a flank of the key face projecting in the direction of insertion of the key.
  • a key is known from AT 396 957 B which has a notch in the area of its teeth next to the key chalk into which a flank, in particular a hook, projects in the direction of insertion. This mostly trough-shaped notch of the key teeth is partially covered by the hook.
  • the key is difficult to rework as a result of this training.
  • the usual key copy milling machines reproduce the wrong key.
  • the torque between the key and the locking cylinder is transmitted very well through the tooth, because the effective bit height in the key channel is at least as large as possible.
  • the key also interacts with a special locking cylinder in that the hook holds the assigned core pin and thus prevents the core pin from dipping into a housing recess and blocking the rotation of the cylinder core.
  • the invention aims to use a key of the type described to achieve an additional function in a special locking cylinder, namely to bring a core pin that is immersed in a locking position into a housing bore into the release position and to hold the core pin in this position.
  • the spring-loaded housing pin assigned to the core pin is designed with a stop for limiting the stroke of its displacement path, the end face of the housing pin lying in the stop position in the interior of the housing bore near the core bore and the end face of the housing pin forms the bottom of a recess into which the core pin is immersed in the locking position, and that the engagement connection between the key and the core pin has at least one inclined surface for lifting the core pin out of the locking position into the release position.
  • the inclined surface can be provided on the key in the area of the projecting flank of a notch of the key face next to the key chalk. In technical reversal, it can also be arranged on the core pin or both on this and on the projecting flank of the key face.
  • a V-shaped groove is provided in the head area of the core pin laterally in the lateral surface and the flank which is arranged on the key face and assigned to the core pin and projects in the insertion direction via a key groove as part of a hook-like tooth with a into the groove of the core pin engaging and lifting the core pin inclined surface is formed.
  • the groove can also be designed as a V-shaped annular groove.
  • a special embodiment is characterized in that a stylus is slidably mounted in a bore of the cylinder core, which opens into the core pin bore and that the stylus from the core pin inserted from the division position into the interior of the cylinder core can be pushed out of the cylinder core into a locking position in which Immerses the stylus in a housing recess.
  • This ensures that a release by the core pin in question is actually only in a single displacement position. If division is not achieved, the cylinder locks because the core pin is still immersed in the recess. If the core pin is lifted over the division, it pushes the stylus laterally into a housing recess and the cylinder is blocked again.
  • the core pin is biased by a spring in the direction of extension from the cylinder core.
  • FIG. 1 shows a longitudinal section through part of a locking cylinder in the locked position
  • FIG. 2 shows the locking cylinder according to FIG. 1 with a suitable key in the release position
  • FIG. 3 shows the cross section to FIG. 2.
  • a lock cylinder comprises a cylinder housing 1 with a core bore in which a cylinder core 2 is rotatably mounted.
  • Five, six or seven rows of core and housing pins are slidably arranged in radial bores in conventional lock cylinder core designs and are displaced from a locked position by the appropriate key in such a way that the respective contact surfaces of the core pins with the housing pins lie in the core bore area.
  • the core and housing pins are shifted by the teeth on the key face or by the notches.
  • the first pin tumbler is shown in the figures. According to the invention, it deviates from the classic functional principle described above.
  • a housing pin 3 is of a stepped design and interacts with a stop 4. The stroke within the housing bore 5 is thereby limited.
  • the end face of the housing pin 3 is in the stop position limiting the maximum stroke (e.g. FIG. 1) set back somewhat from the core bore and forms the bottom of a recess 6 into which the core pin 7 is immersed according to FIG. 1.
  • the cylinder core 2 is blocked in the cylinder housing against twisting.
  • the locking cylinder is locked.
  • the core pin 7 carries laterally - facing the opening of the key channel 8 - as a positive locking element for the purpose of the engagement connection with a key 9 (FIG. 2) a V-shaped groove 10 with an inclined surface 11.
  • a spring 12 acts the core pin 7. If there is no key 9 in the key channel 2 (FIG. 1), the spring presses 12 the core pin 7 out of the cylinder core 2 until the core pin 7 engages in the recess 6 in a locking manner.
  • a conventional key with notches and teeth on the key face will at most push the core pin 7 and the housing pin 3 even deeper into the bore 5 when it is inserted into the key channel 8.
  • the lock cylinder cannot be locked in any of these positions.
  • the correct key 9 has a flank 14 projecting in the insertion direction over the key notch 13 on a hook-like tooth 15 which partially covers the key notch 13.
  • the flank 14 is designed as an inclined surface which corresponds to the inclined surface 11 of the core pin 7.
  • the core pin 7 is held in its release position and it is prevented that it is pressed by the spring 12 into the recess 6 or an additional recess in the rotating area of the core pin 7.
  • a conventional flat key would press the core pin 7 down, the spring-loaded housing pin 3 also withdrawing without division ever being achievable.
  • the core pin 7 is of stepped design, the cylinder core 2 can be turned slightly away from the basic position when the tumblers, not shown, are reached. A further rotation of the cylinder core 2 is blocked by striking the stepped core pin region 7 on the bore wall of the housing bore 5.
  • the core pin 7 is rotatably guided due to its suspension and the eccentric driver pin 16.
  • 3 shows a stylus 17 which lies in a transverse bore to the key channel 8 and which, when the core pin 7 is raised above the dividing surface, displaces it outwards becomes.
  • the stylus 17 then engages in a recess 18 in the housing.
  • the bore for the stylus 17 can be made obliquely to the axis of rotation of the cylinder core 2 so that the stylus 17 does not slide into the recess 6 during the locking process. This can also be prevented in that the stylus 17 is sprung in the direction of the key channel 8.
  • the stylus 17 can be cylindrical or in the area of its engagement as a cuboid slide.
