Definitions

  • the present invention relates to a combination of a profile cylinder and an associated profile cylinder key.
  • Profile cylinder keys are well known. They have a key crayon and a key shaft emanating from the key crayon. Usually located on the key shank recesses for the mechanical alignment of tumblers, which are provided on an associated profile cylinder or lock cylinder. These tumblers consist according to the prior art of core pins and housing pins and are spring-loaded towards the lock core of such a profile cylinder. By aligning the tumblers, which is done with fully inserted profile cylinder key, the parting planes of the core and housing pins are shifted so that ultimately all parting planes are together in the rotational surface of the lock core in the housing of the profile cylinder, so that the lock core is then freely rotatable.
  • profile cylinder key have proven to be excellent, since they provide a high level of security for the honest consumer. Namely, all major manufacturers have committed themselves to copy such profile cylinder key only after presentation of a corresponding security card itself or have copied.
  • a profile cylinder key for a profile cylinder is known.
  • the profile cylinder key has a movable element.
  • From the DE 197 29 234 A1 is also a profile cylinder key with an integrated movable element known.
  • the present invention is therefore based on the object, a combination of a profile cylinder and an associated profile cylinder key so that the copy security is further increased without additional electronic identifiers, etc. are necessary.
  • the access authorization position of the coupling element can be anywhere within the free movement range of the coupling element or also in the range of possible end stops.
  • the profile cylinder key of the combination according to the invention can not be easily on a Kopierfräsautomaten or similar replicate.
  • the coupling element according to the invention also has a certain deterrent effect which will reliably prevent the production of impermissible secondary keys.
  • Essential to the invention is the fact that the two contact areas are present at least in pairs or multiple and that no knowledge of the exact construction of the associated profile cylinder, neither of the two access enabling positions of the contact areas and thus not the access authorization position of the coupling element is recognizable.
  • the coupling element is pivotally mounted on a rotational axis, so that it is moved in opposite directions with its contact areas.
  • the coupling element can also sit in a breakthrough of the key shaft, so that it can be acted upon from both broad sides of the key shaft.
  • the coupling element is arranged as deep as possible in the key channel, that is, as seen from the key tip from preferably in the front region of the profile cylinder key.
  • the key tip itself may also be designed as a coupling element.
  • the profile cylinder key of the combination according to the invention with a coupling element, which forms the key tip itself, has an outgoing from the key tip longitudinal groove, which is arranged on one of the two broad sides of the key shaft.
  • the longitudinal groove is curved and gives the impression that it cooperates with lock cylinder side provided closing elements.
  • the copy security of the profile cylinder key can be further increased by this longitudinal groove, because corresponding copying milling machines with correspondingly many degrees of freedom are necessary for the production of the curvilinear longitudinal groove.
  • the longitudinal groove may preferably be eccentric with respect to the key longitudinal axis and also be arranged point-symmetrically on the key shaft, provided that it is a reversible key.
  • This measure additionally increases the security of copying, because copying the longitudinal groove then additionally requires a corresponding rotational position of the key tip in order to ensure said step-free transition at the attachment point of the coupling element on the key shank.
  • the longitudinal groove additionally has an inlet funnel at its beginning, which can be seen on the key tip.
  • This inlet funnel gives the additional impression of an intended mechanical function of the longitudinal groove on the associated profile cylinder without it being recognizable whether the associated profile cylinder is prepared accordingly or not.
  • the key shank has an approximately 8-shaped cross section is provided with a widened waist region and an associated profile cylinder in its circular cylindrical region with radial tumblers, which are directed substantially all on the key back.
  • An associated profile cylinder is characterized by the fact that it has two additional tumblers, where the coupling shaft is located at the key shaft with its two contact areas, also called coupling tumblers, which are aligned transversely to the broad sides of the key shaft and, just like that like the usual mechanical tumblers sitting in bores of the lock core on the one hand and the housing of the profile cylinder on the other.
  • the coupling tumblers each corresponding to one another are then aligned so that the locking core, assuming a suitable profile cylinder key, is freely rotatable.
  • the coupling tumblers can be spring-loaded individually or repeatedly.
  • This non-spring-mounted guard locking can also be referred to as passive guard locking. It aligns via the coupling element, the spring-loaded coupling locking in terms of a rotational release of the lock core.
  • the movable coupling element has the function to align the two mutually corresponding coupling tumblers mutually so that both coupling tumblers release the rotational movement of the lock core together.
  • Another embodiment of the combination according to the invention provides for a profile cylinder key with a coupling element on the key tip inside the housing of the profile cylinder to provide a non-rotatable coupling disc whose contour corresponds exactly to the contour of the coupling element on the key tip, the coupling element on the key tip back and is pivotally mounted and can fit for this reason in a corresponding recess of the coupling disc, if it is the appropriate profile cylinder key.
  • the coupling element also has the contact areas according to the invention, which are then adapted to the contour of the coupling disc and vice versa.
  • the contact areas serve in each case but also the alignment between the insertion depth of the profile cylinder key and the achievement of a corresponding rotational release of the usual tumblers, which can be guaranteed only by a correct insertion depth.
  • the coupling element during insertion of the profile cylinder key in the lock core of the lock cylinder within the outer contour of the key shaft and occurs when turning the lock core partially on the outer contour.
  • the profile cylinder key can be easily inserted into the keyway without the coupling element blocking the insert. Only after the profile cylinder key has been fully inserted, the coupling element is deflected and occurs on the outer contour of the key shaft. However, this takes place only when the lock core has been slightly rotated, so that the profile cylinder key can not be removed. In this case, the coupling element in its access authorization position partially protrudes beyond the outer contour of the key shaft.
  • two coupling tumblers engage the coupling element, at least one coupling tumbler having a core pin and a housing pin.
  • the section of the housing pin pressing the core pin into the lock core engages in a recess receiving the core pin in the lock core, the cross section of which is greater than the cross section of the section.
  • the portion has a smaller diameter, as the abutting head of the core pin.
  • the coupling tumblers are arranged substantially radially in the lock core.
  • a coupling locking on its side facing away from the coupling element side has a lenticular or spherical portion-shaped head which engages in a receiving recess in the profile cylinder housing.
  • the housing pin is spring loaded in the direction of the core pin.
  • the coupling tumblers engage on opposite sides of the coupling element on this.
  • the coupling element serves e.g. as a rocker for the coupling tumblers.
  • the figures essentially show a profile cylinder key 1.
  • a profile cylinder key 1 has a key crop 2.
  • a key shank 3 which extends to the key tip 27.
  • the key shank 3 is provided with recesses 4.
  • the recesses 4 are used to align tumblers 5, which are usually provided in the lock cylinder.
  • the tumblers 5 consist of core pins 6 and housing pins 7 and are usually acted upon by compression springs in the direction of the lock core 13.
  • the bores can be arranged either in the circular-cylindrical housing part 11 and / or in the web-like housing part 12 of the housing 10 of the profile cylinder 9.
  • the coupling element 15 It is essential that at the key shaft 3 a reciprocating between two end positions arranged coupling element 15 is seated.
  • the coupling element 15 has two or more contact areas 17,18,19,20, which are accessible in the use position of the inserted in the associated profile cylinder 9 profile cylinder key 1 from outside the key shaft 3 and, so to speak, closing cylinder side.
  • the coupling element 15 By acting on the contact areas, the coupling element 15 is aligned in the sense of possible reciprocating movements, so that it is displaced by the orientation in an access authorization position in which the intended contact areas 17,18,19,20 predetermined positions with respect to the rotational surface fourteenth occupy the lock core 13 in the profile cylinder 9.
  • the locking core 13 is rotatably mounted in the circular-cylindrical housing part 11 of the housing 10 and forms the so-called rotary surface 14 along its common lateral surface with the inner surface of the locking core bore 35.
  • This rotation surface 14 is usually traversed by the tumblers 5 and beyond also by further coupling tumblers, which are arranged in the profile cylinder 9 and will be discussed later.
  • the coupling element 15 is pivotally mounted on a rotation axis 22. This means that the coupling element 15 can be pivoted back and forth about the axis of rotation 22 and in this way gives the impression that such a profile cylinder key can not be easily reworked by a Kopierfrässtrom.
  • the bearing of the coupling element 15 can be replaced by a simple axial bore in the key shank by e.g. take a chosen notched pencil.
  • the figures show a special feature.
  • This measure offers the additional possibility of executing the profile cylinder key 1 as a reversible key on which the recesses 4 provided are then correspondingly symmetrical.
  • An essential idea of the invention is also based on the fact that the inventive possibilities of the coupling element lead to select those act on contact areas 17,18,19,20 with respect to the profile cylinder key and of course also with respect to the key channel, which move in opposite directions.
  • Figure 2a - 2c and 3a show for this purpose that the contact areas 17, 18 and the further contact areas 19, 20 can also be accessible from both sides of the key shaft 3.
  • the coupling element 15 is arranged in the front third between the key tip 27 and the key crop 2, the corresponding coupling tumblers, which will be discussed, would sit deep in the keyway, so that manipulation attempts will be made considerably more difficult.
  • FIGS. 2a-2c and 3a show the interaction of the profile cylinder key according to the invention with an associated profile cylinder.
  • Such a profile cylinder 9 has in its housing 10, either in the circular cylindrical housing part 11 or in the web-like housing part 12, mechanical tumblers 5, which consist of core pins 6 and housing pins 7.
  • FIG. 1 a single such tumbler is shown by way of example. It is aligned by a corresponding recess 4 on the key shank so that the dividing plane between the core pin 6 and housing pin 7 is exactly in the rotational surface 14, which circumscribes the lock core 13. Since all these tumblers are aligned by a matching key, the lock core 13 can then rotate freely.
  • at least two further tumblers are provided here in the present case, referred to in the present case as Koppelzunnenen 28, 29, which also consist of core pins 6 and housing pins 7.
  • the core and housing pins of the coupling tumblers 28, 29 are aligned with each other and are in this way within the longitudinally displaceable both partial bores.
  • the coupling tumblers 28, 29 are one-sided (see FIG. FIG. 2a . 3a ) spring loaded.
  • the individual contact areas 17-20 could be varied accordingly to produce an even greater burglar resistance.
  • there are 2 4 16 variations for four contact areas.
  • FIG. 2a - 2c and 3a a variant in which of the provided coupling tumblers 28, 29 is only a single spring loaded, while the other coupling tumbler 29 is designed as a passive element, which aligns the spring-loaded coupling locking on the coupling element.
  • the coupling element 15 is displaced by the spring-loaded coupling tumbler until the non-spring-loaded coupling tumbler 29 has run to the stop. In this position, this indicates Coupling element 15 then the access authorization position 21, in which a matching profile cylinder key 1 has then aligned the usual mechanical tumblers 5 to open the door.
  • FIGS. 2a-2c and FIGS. 3a and 3c show a further exemplary embodiment.
  • FIG. 2a shows the orientation of the two coupling tumblers 28,29 with respect to the key channel 40 o, key core 13th
  • Both coupling tumblers 28, 29 extend a small distance into the keyway 40.
  • the passive coupling lock 29 is integrally formed and rests with a dome-shaped Protrusion 38 in a corresponding locking recess 39, which is provided on the housing side.
  • This passive coupling lock 29 has only one core pin 6, no housing pin.
  • the sprung coupling tumbler 28 is constructed in two parts and has a core pin 6 and a housing pin 7.
  • a compression spring 8 pushes the core pin and the housing pin inwards in the direction of the key channel 13, where the tip of the core pin protrudes a little way into the keyway 13.
  • the coupling element 15 lies in the same radial plane as the coupling tumblers 28, 29, but the passive coupling tumbler 29 lies against the pivotable coupling element 15, which in turn bears against the inwardly directed tip of the core pin 6 of the sprung coupling tumbler 28.
  • the core pin 6 in turn pushes with its outwardly directed surface against the head of the housing pin 7, which in turn is pressed by the compression spring 8 in the direction of the keyway 13.
  • the passive Koppelzuiens 29 is movable radially inwardly
  • the coupling element 15 is pivotally movable in a clockwise direction
  • the sprung Koppelzurien 28 is movable radially outward.
  • the head of the housing pin 7 of the sprung coupling tumbler 28 is smaller in diameter than the mutually aligned partial bores in the housing 10 on the one hand and in the lock core 13 on the other. It forms, so to speak, at the head of the housing pin the diameter step 50.
  • the lock core 13 is thus able to rotate with respect to the sprung Koppelzulets 28 until it abuts with its bore wall on the smaller diameter head of the housing pin of the sprung Koppelzurien 28.
  • the passive coupling locking device will slide with the central region of its dome-shaped protuberance on the inner circumference of the housing, in which case it has rotated the coupling element 15 clockwise by the dimension A, which ultimately corresponds to the movement region 16.
  • This measure corresponds to taking into account the gear ratios the dimension A ', which corresponds to the distance between the common contact surface of the core pin 6 and housing pin 7 to the rotating surface 14.
  • the diameter stage 50 which, in this exemplary embodiment, permits a rotational movement of the lock core 13 in order to interrogate the exclusion criterion of a coupling element 15 tuned to the coupling tumblers 28, 29 at the end of this movement scope.

  • the longitudinal groove 37 on the tip side of the profile cylinder key on an inlet funnel, which gives the additional impression that in this longitudinal groove a locking cylinder side provided locking element can / should dive.
  • the main advantage of the invention is based on the fact that on the one hand can not be reliably assessed whether the coupling element 15 is needed for a profile cylinder to be closed, since the coupling element does not allow this unambiguous statement, but on the other hand, the coupling element can not be easily reworked by a Profilfräs vide because the exact access authorization position 21 of the coupling element 15 in the insertion position of the profile cylinder key 1 can not be seen without detailed knowledge of the construction of the profile cylinder 9.
