Definitions

  • the present invention relates to reversible key for profile cylinder Oberbergriff the main claim.
  • the invention relates to a system of reversible keys and a system of associated profile cylinders according to the preamble of claim 5 and profile cylinder and reversible key according to the preamble of claim 8.
  • the invention is based on a reversible key, which is also referred to as a flat key and serves to close an associated profile cylinder.
  • Such reversible key has on its two narrow edges incisions of different cutting depths, which serve to align the profile cylinder in a row provided pin tumblers so that the lock cylinder can be actuated.
  • both narrow edges of the key shaft are provided with mutually mirror-inverted cuts, so that the reversible key into the keyway of the lock core in the two possible by 180 degrees offset insertion positions, in the present application can be inserted as key reversal positions.
  • These complementary pin tumblers are located at the inner end of the lock cylinder and correspond in their structure in principle the usual pin tumblers consisting of core pins and cylinder pins and possibly philosophicalstatten.
  • a further sub-task of the invention is based on specifying measures on the profile cylinder, with which a blocking or release of the lock cylinder via a correspondingly designed reversible key is possible beyond the known pin tumblers addition.
  • the invention is characterized in that in addition to the usual cuts on the narrow edges and possibly provided holes on the broad sides of the key shaft for aligning any laterally arranged pin tumblers on each broadside an additional Konturfräsung is provided on one and the same reversible key having the variation edges which are not readily copied on conventional machines after location, distance from the key tip and geometric course.
  • each of the two variation edges must be made separately in terms of their distance from the key tip, their geometric shape, their width and still the relative positions of both edges variation must also be taken into account.
  • the invention provides the advantage that an impermissible copy of such reversible key can only be produced at considerable expense, so that the reversible key according to the invention actually offers considerably better copy security than the known systems.
  • the reversible key according to the invention therefore opposes the interests of the consumer in terms of increased copy security, in particular also because the variation edges should preferably be perpendicular to the broad sides of the key shaft.
  • a cutting tool which stands with its axis of rotation perpendicular to the broad sides of the reversible key, such as a cylindrical milling cutter and a corresponding scanning device.
  • the two variation edges must be arranged on each broad side of the reversible key with respect to the two possible key reversal positions mirror images of each other. This requirement requires increased manufacturing precision.
  • the measures of the present invention also allow the use of such reversible key and possibly assigned profile cylinder in addition to existing locking systems, because the reversible key according to the invention is indeed designed to close subordinate profile cylinder, but their reversible keys are not suitable to close parent profile cylinder.
  • the invention also provides the possibility to supplement locking systems with existing profile systems, if necessary in the sense of improved copy security.
  • the reversible key could be the lowest hierarchy EP 1 503 010 A1 be made while at least the reversible key highest Hierarchy must have the features of the present invention.
  • Embodiments are also conceivable in which the reversible keys of the middle hierarchy have either no or only a single variation edge per broad side on their broad sides.
  • the invention also improves the possible number of variations within already existing locking systems, but in particular improves the copy security of the turning key of the highest hierarchy.
  • the two variation edges are formed on each broad side of the reversible key of two successively arranged pockets, of which the key tip facing pocket starts with a relatively large width.
  • this first pocket joins a smaller bag with a smaller width and continues a bit towards the key crop.
  • the second variation edge is formed in this way, while the variation edge of the first pocket is formed by the end of the pocket facing the crayon.
  • variation edges can transversely, obliquely, perpendicularly or curved to the longitudinal direction of the key shaft, they only need to cut its longitudinal direction in any way, so that when inserting the reversible key in the profile cylinder a standing transversely to the insertion direction stop edge on the reversible key is ready.
  • An optimal stop variation results e.g. at variation edges, which - in the longitudinal section of the reversible key - are perpendicular to the broad sides of the key shaft.
  • both stop projections are arranged one behind the other in the longitudinal direction of the key channel and in the transverse direction at the level of each associated variation edge of the inserted reversible key.
  • variation slide Since the variation slide is seated within a longitudinal recess of the lock core, it can be displaced by interaction between the variation edge and associated stop extension within the lock core and be used for the operation of complementary tumbler elements.
  • the variation slide on a release pocket, which can engage with corresponding axial positioning within the longitudinal recess in the lock core of the transverse extension of a locking bar, so that the locking bar is displaced from its locked position to its release position.
  • both the stop geometry of the variation slide and the arrangement of the variation edges can in principle be selected freely, so that reversible keys of the present invention can create additional hierarchies as a supplement to existing systems and also enable very different security requirements.
  • the reversible key according to the present invention and the corresponding profile cylinder with their variators for the respective hierarchy or security requirement as far as possible to settle, for example, in a general master key and important parent keys or even single key to doors special security requirements.
  • the figures show a reversible key 1.
  • the reversible key 1 is designed as a flat key and can be inserted into two offset by 180 degrees to each other insertion positions in the keyway 26 of the profile cylinder.

  • each recess 8 on the key tip 7 begins with a pocket of constant width 17, to which a further pocket of lesser width 17a joins in the direction of the crayon 3.
  • the variation edges 12, 13 are respectively formed by the end portion of each pocket.
  • each pocket consequently, an edge region extending transversely to the longitudinal direction 9 of the key shaft 2 is formed, which leaves the respective variation edge 12 or 13 formed.
