Definitions

  • the invention relates to a lock-key system. consisting of a key, a Cylinder housing in which the cylinder core is rotatably mounted, which has an axially extending Key channel for receiving the key and from tumblers, the interact with notches on the key.
  • Lock key systems of this type are well known.
  • the most common Occurring systems flat keys are used, the breast side, the mechanical Coding having notches, with tumbler pins in the cylinder housing interact.
  • these flat key profiles have, in Form of at least partially axially along the side surfaces vedaufenden grooves and / or Projections.
  • the actual locking system, i. the tumblers are thus in the housing accommodated. Due to this, the shape of the cylinder housing is then given, with the round - the cylinder core receiving part - and the adjoining Flange. This type is also called DIN profile cylinder.
  • US-A-2690070 is a lock-key system with a notched key, a cylinder core with grooves and with arcuate tumblers, a keyway, a movable locking bar and sliding tumblers, which are aligned by the notches of the key and so allow the closing known.
  • the notches are in this system at the longitudinal edges of the key ie each notch is assigned to this tuned, curved tumbler element, so that this type of coding requires a large storage of completely different tumblers.
  • the invention is based on the object, a lock-key system of the beginning mentioned type so that on the one hand a small footprint for the installation of the Castle is necessary and on the other hand, a large number of closing variants possible is.
  • reversible keys can be used but also asymmetrically designed keys that allow for double-sided scanning an extremely high number of locking variants.
  • shape of the key leads to a significant Festigkertsverêtung on the key, compared with the usual flat keys.
  • the cylinder housing 1 In the cylinder housing 1 is rotatably arranged the cylinder core 2. This points a keyway 7, which - as seen in the figure - arranged asymmetrically is.
  • grooves 5 are provided, extending over part of the circumference extend.
  • segment-like tumblers 4 are displaced, namely against the force of springs 6.
  • the shape of the tumblers 4 is the shape of the grooves adapted, i. they are according to the radius of the cylinder core and the grooves bent.
  • the displacement of the tumblers 4 is indicated by the notches (coding) of the Key determined. This is located on one or both side surfaces and run transversely to the longitudinal extent of the key and parallel to the respective Side surface.
  • a locking bar 10 cooperates, which can be pressed under the force of a spring 11 radially outwardly into a recess 14 in the cylinder housing. In this state, it bridges the dividing line cylinder housing / cylinder core, so that a rotation of the cylinder core in the cylinder housing is not possible.
  • the tumblers 4 each have a recess 13 and these recesses altogether by the displacement of the tumblers - with correct coding of the Key - aligned so that the locking bar 10 is moving radially inward this can dip.
  • This radial movement of the locking bar 10 against the force of Spring 11 is made possible by bevels 12, which when turning the cylinder core on corresponding slopes of the locking bar act. It is clear that every wrong coding the key leads to a different displacement of the tumblers, so that then no alignment of the recesses 13 takes place and thus no closing operation is possible.
  • Fig. 4 an embodiment is shown in which the notches on the side surface so are arranged that a scan from both sides is possible parallel to the side surface.
  • FIG. 5 A further variant results from FIG. 5, in which case a reversible key is shown is, with notches on both side surfaces of the key and to both sides in the sense the embodiment of FIG. 4th
