Definitions

  • the invention relates to a security lock cylinder with tumblers actuated by a key.
  • the object of the invention is to make it considerably more difficult to move the tumblers without a key without deviating from a locking cylinder of simple, economical and very robust construction.
  • the locking cylinder according to the invention is characterized in that the tumblers each have a part in the form of a cylindrical pinion, which interacts with a part of the incision on the key.
  • the complete insertion of the key gives each tumbler a certain angle position which, provided that the key used corresponds to the locking code, unlocks this locking cylinder.
  • each tumbler comprises a thread which engages with an internal thread of the cylinder core. During the rotation, each tumbler is thus also shifted, so that the unlocking takes place when all tumblers have moved into the interior of the cylinder core.
  • the locking cylinder includes tumblers 3, 3 ', 3' ', 3' '', of which part 1 is provided with a thread and part 2 has the shape of a pinion.
  • Leaf springs 4 and 5 ensure the angular indexing of the tumblers.
  • a key 6 inserted into the key channel 6 'of the cylinder core 5 comprises toothed areas 9, 10, 11, 12, which form the same number of toothed racks for interaction with a tumbler 3 or 3' or 3 '' or 3 ''' ' .
  • the distance 7 between the racks 9 and 10 and the distance 8 between the racks 11 and 12 are such that each rack only acts on the adjacent tumbler.
  • the depth of insertion of the key into the key channel 6 ' determines for each rack a number of teeth which interact with the corresponding tumbler, as a result of which a single angular position is specified for each tumbler after the key has been inserted.
  • each tumbler interacts with a thread of its seat in the cylinder core 15 so that the rotation thereby communicated is translated into a shift of the tumbler.
  • the locking cylinder just described is particularly simple, robust and economical because the number of parts used is greatly reduced.
  • the tumblers 3, 3 ', 3 ", 3"' ' can all be of the same drawing or of the same shape.
