Definitions

  • the invention relates to a security key Preamble of claim 1.
  • Such a security key is known from US Pat. No. 3,568,481 known.
  • the locking recesses run across the Key chest and serve to align cylindrical core pins.
  • the core pins run with their rotating Pointed edges on the sloping flanks of the recesses on. This singular contact zone favors in particular for new pairings from security key and Lock cylinder considerable initial wear.
  • the Locking recesses jump behind the outer contour surface of the Back of the key.
  • Each of the recesses has a central one Rest area. This locking surface is used for height adjustment of the core pin.
  • the locking areas form depth coding in cooperation with core pin and housing pin, so that in the release position when core pin and body pin have fallen into the recess, the gap between Core pin and housing pin exactly in the parting line between The core and housing of the locking cylinder is located and therefore the Rotation of the core in the housing releases.
  • the tumblers are on the outside of the housing pin spring-loaded to the positive scanning of the locking recesses to ensure.
  • When inserting the security key drive the recesses on the core pins over, with the core pins above all upstream Drive away inclined flanks and recesses until the safety key has reached its end position. You can also drive through several recesses under the core pins, if namely the locking recesses in the direction of insertion seen lying in a row.
  • pulling out of the key must first be the static friction of the core pin be overcome in the recess. Then drive the recesses under the core pins and shape this one corresponding to the geometry of the inclined flanks Inclined upward movement.
  • the core pin When inserting and removing the security key the core pin in its radial guide hole one by the order of the passing recesses predetermined sequence of radial motions, and that against the spring force of the tumblers at Get out of a recess and in the direction of the spring force when immersed in a recess.
  • Another security key is known from EP 0 651 117 known for locking cylinder, the key back of two parallel circular cylinders is formed.
  • the recesses are frustoconical depressions in a cylinder surface, the cone axis of the locking recesses perpendicular to the cylinder axis.
  • the recesses can with this security key essentially over the whole The scope of the security key must be distributed.
  • the conical lateral surfaces form the inclined flanks in the longitudinal direction for the core pin that comes with the key as it passes over these inclined flanks in and out of the recess the recess can slide out again.
  • the base of the core pin which is usually chamfered is the transition from the locking surface to the sloping flank comprehend.
  • the base of the core pin which is usually chamfered is the transition from the locking surface to the sloping flank comprehend.
  • the geometry of the transition therefore requires very tight tolerances the edge curvatures of the base of the core pin and the edge of the recesses to prevent wear through the use of the Avoid security key. If this aspect is neglected, which is sometimes the case with duplicate keys copied by third parties occurs, these inadmissible copies often tend after some time to "hook" in the lock cylinder, if one or more core pins on a sloping flank hit and need to be raised. The operation is thereby over time more difficult and also less secure; because both the core pins of the locking cylinder and the Oblique edges of the security key are caused by the trend loaded for inhibition in the axial direction.
  • the object of the invention is therefore a security key of the type mentioned in such a way that also a copied security key when inserting and removing slides practically uninhibited and that the wear of the security key and the core pins of the Lock cylinder remains so low that the lock cylinder cannot be discredited by copied duplicate keys.
  • the invention has the advantage that the core pins continuous and therefore uninhibited according to the geometry immerse the recesses in and out of them rising up.
  • the invention is based on the finding that in the conventional geometry of the recesses a certain Inhibition of the core pin when it is chamfered Lateral surface takes place on the inclined flank. This Inhibition points are eliminated by the invention.
  • the inhibition points - the transitions between the rest area and their sloping flanks - are rounded out as concave Sliding surfaces formed. Due to the concave fillet Singularities - such as Corners or edges - on the glide line the transition excluded.
  • the force in the longitudinal direction of the Key with which the security key is inserted and is pulled out, is always outside the friction cone, especially in the area of the sloping flanks. Through this The self-locking of the key is excluded.
  • the demand is supported by the proposed rounding and the tangential fit also for the sliding surfaces automatically fulfilled.
  • the friction cone is a measure of what is expected Wear. This is always larger in the area of the sliding surfaces or equal to the angular distance in the area of the inclined flanks and approaches the value in the area of the sloping flanks.
  • the base of the core pin is in the process of being inserted or pulling out always in a continuous Sliding friction condition.
  • the usual breakaway torque at the point of impact on the sloping flank, due to the singular Transition is avoided in the invention.
  • the key slides with reduced sliding resistance into and out of the locking cylinder, which means easier operation and increased operating safety surrender.
  • the impression is also perfect for the user sliding function of the lock pairs without any hook of the key.
  • the invention thus offers maximum ease of use with reliable and low-wear interaction of security key and lock cylinder.
  • the sliding surfaces can be designed inconspicuously. Then they are hardly for an uninformed specialist noticeable, so that this the security key in the Usually copied without the corresponding sliding surfaces.
  • One without the trajectory of the recesses of copied keys is comparatively easy to identify as a plagiarism, since it differs from the original on closer optical examination with the trajectory. It also runs in such plagiarism is not so easy from the very first moment Core pins away like the original or an acceptable copy according to the present invention.
  • each rest area goes over a key tip side and a key flank side sloping flank into the respective sliding surface. Every recess is there always from sloping flanks and within the sloping flanks lying rest area. In the described configuration runs through a core pin until it reaches it End position of several recesses. Their inhibitions become eliminated by the described configuration.
  • the transitions between the inclined flanks and the outer contour surface of the The back of the key is designed as a convexly rounded sliding surface are in the longitudinal direction of the key back both on the sloping flanks and on the outer contour surface of the back of the key nestle tangentially.
  • the Transitions are concave on the locking surfaces and on the back of the key convex. All transitions are done with little Sliding resistance sampled because they are designed without singularities are.
  • conical locking recess radially outer transitions do not generally inhibit the key to lead; but they are operating the key noticeable and thus also affect the movement of the Closing pairing.
  • the proposed design creates hence a smooth security key that is reliable and practically even the impression of a mechanical actuation of the tumblers reduced to prevented.
  • transitions mentioned are convex fillets. At the manufacturing has the advantage that each recess milled practically throughout in the form of a curve can be. All transitions are in the form of fillets, so that synergy effects play a role in manufacturing.
  • the transitions (two or four different types) only have to programmed once, for example in a CNC machine and can then be used for every recess become.
  • the locking recesses with the exception of the locking surfaces than in the longitudinal direction of the
  • the back of the key is formed with rounded curves are. Only the discharge zone on the key spider side extremely recessed recess can be of this be exempted.
  • the key spider side facing away Sloping flank of this recess is namely in normal never apply a core pin to use.
  • the position of the locking surfaces and the spacing of the locking recesses from each other in the longitudinal direction of the key back are blurred if there are two opposite each other Sliding surfaces of a recess with different Radii of curvature are curved. Then the center of the rest area not exactly the center of the recess, because the Sliding surfaces of a recess have different radii of curvature and, as a rule, also different longitudinal extensions exhibit.
  • the spacing of the recesses is then also can no longer be determined by their edge distances.
  • the proposed design offers the advantage that sliding essentially equidistant on one Longitudinal recesses not for all corresponding Core pins are made synchronously.
  • the multiplication of the mechanical forces when the core pin slants abut the Sloping edges of the locking recesses of a conventional one Key is replaced by the addition of smaller, mechanical ones Powers.
  • the security key is softer overall.
  • the width of the sliding surface in the key direction is larger than the width of the contact zone of the Base of a core pin with the sliding surface in the overrun position of the core pin on the sliding surface.
  • the sliding surface should be the specified width over its entire length seen not fall below. It is particularly important that the width of the sliding surface in the key cross direction on Transition from the locking surface to the sliding surface of the same size or is greater than the width of the contact area of the foot of one Core pin.
  • the specified widths are those in the transverse direction of the key back projected transverse dimensions.
  • This width of the contact zone can vary from the width of the base of a core pin. This is for example, the case when the recess in the has a substantially frustoconical shape.
  • cylindrical Core pin can be the curvature of the root circle of the core pin smaller than the curvature of the outer circle of the truncated cone be at the level of the rest area. Then the contact zone - with a smaller root circle of the core pin - smaller than that Total width of the core pin. Nevertheless, the contact zone a flat extension.
  • the unrestricted emergence is then always automatic realized when the width of the sliding surface in the key cross direction greater than or equal to the width of the base of the core pin is. Then the contact zone of the base of the core pin lies with the sliding surface in the run-up position of the core pin always within the width of the sliding surface in the key direction. This means that gliding is uninhibited given.
  • the width of the sliding surface is preferred larger over the entire longitudinal extent of the sliding surface or equal to the width of the base of a core pin. Then too mechanical inhibition points within the sliding surface excluded.
