Definitions

  • the invention relates to a security lock cylinder with tumblers actuated by a key, the tumblers each comprising a part in the form of a cylindrical pinion which interacts with a toothed rack part cut into the key.
  • a device of the type mentioned is known from the prior art (FR-A1478981).
  • the locking part is locked by rotatable levers. These levers are turned by pinions, which in turn are turned by the teeth on the key. In this way, the forward movement of the key causes the gears to rotate and the levers above them to rotate.
  • each tumbler comprises a thread that interacts with an internal thread of the cylinder core.
  • the invention offers the further advantage that, due to the four tumblers used, the number of possible coding combinations is significantly higher than in the prior art (two gearwheels).
  • Each tumbler includes a thread that engages 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 as many 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 thus communicated is translated into a displacement and 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.
