Definitions

  • the invention relates to a lock cylinder comprising a lock cylinder housing with a housing bore limited by an inner circumferential surface, a lock cylinder core rotatably received in the housing bore about an axis of rotation with a key channel which, starting from a key insertion end at one end of the lock cylinder core, runs essentially parallel to the axis of rotation and for receiving of profile-adapted keys with at least one level-oriented control track running approximately parallel to the axis of rotation in at least one side surface, and at least one spring-free tumbler pin in at least one guide bore of the lock cylinder core, the bore axis of which lies approximately in a tumbler plane orthogonal to the axis of rotation and runs towards the control track, wherein this tumbler pin can be moved in the guide bore along its bore axis and - after in a basic rotational position of the lock ß cylinder core detected introduction of a profile and mysterious key - is set or adjustable in a release position in which it allows a desired functional release rotation of the lock cylinder core about
  • Such a lock cylinder is known from DE-PS 31 23 511 and DE-OS 20 03 059.
  • the object of the invention is to achieve a further increase in locking security.
  • the invention proposes that an axial sliding element is slidably received in a sliding channel of the locking cylinder core running parallel to the axis of rotation, which is biased by spring means into a locking position close to the end of the key insertion and is axially displaceable unlockable by a driving surface of the entering profile-adapted and secret-adapted unlocking key which is approachable against the driving stop , wherein the axial sliding element blocks the displacement of the tumbler pin in its guide bore in its locking position and releases the displacement of the tumbler pin in the guide bore in its release position.
  • a lock cylinder is known from German Offenlegungsschrift 34 24 336, in which the lock cylinder core can be locked in a conventional manner by keychain-controlled, spring-loaded tumbler pin pairs which, when the mysteriously adapted key is inserted, are arranged with their parting planes in the parting surface between the lock cylinder core and the lock cylinder housing.
  • An axial sliding element is already provided in the lock cylinder core, which interacts with a core-side tumbler pin of a spring-loaded tumbler pin pair.
  • the axial sliding element is axially biased by a spring in the direction of the entrance of the locking channel and can be axially displaced by a rib formed on the associated key, namely by its front end when the key is inserted.
  • the axial sliding element engages in an annular groove of the tumbler pin at the core, so that it is locked against displacement.
  • the associated key When the associated key is inserted, it first hits the stop surface of the axial sliding element with the front rib end, so that this is shifted and in the course of this shift comes with a constricted area in opposition to the core-side tumbler pin. Then the core tumbler pin can be moved through the key tip and the key chest. To really move the core-side tumbler pin, the key must be pushed in even further. With this further insertion of the key, the axial sliding element is moved further.
  • the constriction of the axial sliding element must be dimensioned such that during the entire remaining insertion path of the key (this is the insertion path, which begins with the beginning of the action of the key tip on the axial sliding element and only ends when the key is fully inserted into the key channel) the core-side tumbler pin remains in the region of the constriction.
  • the spring-free tumbler pin is locked by the axial sliding element when the key is pulled, in an external position, so that it is not acted upon by the key when it is inserted.
  • the key can thus be fully inserted into the key channel without interaction with the at least one springless tumbler pin. It is therefore completely irrelevant in which phase of the key insertion path the axial sliding element is carried by the key. It is sufficient if the axial sliding element shortly before the key insertion path is completed just so much is taken away that it is transferred from its locked position to its release position.
  • the release position of the axial sliding element is only required if, after the key has been inserted, a rotation of the lock cylinder core relative to the lock cylinder housing is initiated. For this reason, it is not necessary in the embodiment according to the invention to design the axial sliding element over a larger axial region of its length to release the tumbler pin.
  • the axial sliding element is designed to release the springless tumbler pin only in such a length that in a single position forced by the fully retracted key it enables the springless tumbler pin to be released for its subsequent insertion movement by turning the cylinder core.
  • the locking and release effect between the tumbler pin and the axial sliding element can be made possible in that the tumbler pin and the axial sliding element are arranged so as to intersect in the locking cylinder core, wherein in the locked position of the axial sliding element this engages in a tumbler pin cutout and in the released position of the axial sliding element the tumbler pin is displaceable through a sliding element recess.
  • the tumbler pin recess is adapted to a profile of the axial sliding element such that the tumbler pin is fixed in the guide bore in the locking position of the axial sliding element essentially without play or / and that the sliding element recess is matched to a profile of the tumbler pin in such a way is that only in a single defined position of the axial sliding element corresponding to the release position of the axial sliding element is a displacement of the tumbler pin in its guide bore possible.
  • the entrainment of the axial sliding element by the key can be made possible in that the entraining surface of the key is formed by the end pointing towards the key tip of a longitudinal groove running from this end towards the key tip in a key side surface, in particular the key side surface having the control track, and in that the axial sliding element has a driver stop projecting in the direction of the key channel, which is received by the longitudinal groove when it is inserted into the key channel.
  • the solution according to the invention also increases the possibility of closing variations. It can be easily imagined that in a lock cylinder according to German Offenlegungsschrift 20 03 059 or also according to German Patent 31 23 511, by installing the axial sliding element according to the invention for interaction with one or more springless tumbler pins, the number of closure variations can be increased considerably, by influencing one, several or all of the springless tumbler pins by the axial sliding element and further by changing the locking cylinder or / and associated key by varying the position of the driving stop of the axial sliding element and / or by varying the driving surface of the associated profile-adapted and secret-adapted key. This is particularly important for the locking system application.
  • the protection against unauthorized breaking of the locking cylinder according to the method of core pulling is significantly increased by the invention. If, when the key is pulled, the axial sliding element holds one or in particular a plurality of tumbler pins in an external position in its locked position, by the tumbler pin or pins engaging in one or more recesses, this action counteracts the core pulling.
  • the housing-side ends of the spring-free tumbler pins then dig into the in an attempt to pull the core, in particular according to the so-called corkscrew method a respective recess of the inner peripheral surface of the lock cylinder housing, at least when the recess or the recesses are limited in the axial direction.
  • the springless tumbler pins are jammed between the inner circumferential surface of the housing and the axial sliding element at the latest when, during the course of an extension movement, a tumbler pin with its end near the housing abuts against an axial limitation of the recess.
  • the sliding channel can be designed as an axial bore which is separate from the key channel and is only connected to the key channel by an opening over part of its length, this opening allowing a driving engagement between the key and the axial sliding element. In this way, reliable guidance of the axial sliding element in the sliding channel that is not jammed is maintained.
  • the opening should be closed at at least one end, that is to say the end on the key insertion side.
  • An opening in the other direction can be advantageous for the production.
  • the driving stop of the axial sliding element can be formed by a stop pin which penetrates the opening and, if appropriate, is received in a diametral bore in the axial sliding element.
  • the spring means acting on the axial sliding element can be formed by a helical compression spring which is supported at one end of the sliding channel.
  • the recess on the inner circumferential surface of the core receiving bore which is intended to engage the at least one tumbler pin, can in principle be formed by a longitudinal groove in the inner circumferential surface parallel to the axis of rotation, which is open in the axial direction at at least one end.
  • the opening of this channel at one end is very advantageous for the production of this channel by broaching, drilling or milling.
  • the recess may be desirable for the recess to be limited in the axial direction by a pull-out inhibiting surface which interacts with the outer pin end. If several springless tumbler pins are provided and if one wants to use all or at least some of them to secure the lock cylinder core against being pulled out, it is recommended that the axial extent of the recesses in the inner circumferential surface of the core receiving bore approximately corresponds to the axial extent of the respective outer pin end.
  • the inner and / or the outer pin end can be designed approximately as a partial spherical surface. Other surface designs are also conceivable. It is only necessary that the inner pin end cooperates with the level-varied control path of the key broadside and that the outer end of the tumbler pin cooperates with the respective recess in the inner peripheral surface of the core receiving bore when a rotary movement of the lock cylinder core is initiated.
  • the cam-like interaction of the inner tumbler ends with the level-varying control path takes place when, after the lock cylinder core has been rotated, the key is pulled in the zero position of the lock cylinder core intended for pulling the key, and those previously controlled in a radially inward direction when the lock cylinder core is turned Tumbler pins have to be pushed radially outwards again, into a position in which the axial sliding element returns to its blocking position and blocks the tumbler pin (s) in their outer position.
  • the locking cylinder can additionally be designed with spring-loaded pin tumblers, which are each formed from a core pin and a housing pin, these pins being aligned with one another in the basic rotational position of the locking cylinder core (zero position) and abutting against one another with separating surfaces. These dividing surfaces are then set in the area of the inner circumferential surface by means of a toothed key chest if the correct secret adapted to the key is used.
  • the invention can basically be carried out with a single springless tumbler pin in cooperation with an axial sliding element, but that a preferred embodiment has a plurality of tumbler pins on at least one side of the key, these tumbler pins insofar as they relate to and same side of the key are arranged by a common axial sliding element can be influenced.
  • the interest pins have the same length and that the recesses of the inner circumferential surface assigned to them and the level sinks of the control track have the same depth.
  • tumbler pins of different lengths are used, and accordingly the depth of the recesses and the level sinks is also varied.
  • a lock cylinder of the type considered here differs from lock cylinders of the same basic design at least by different axial position of the driving surface of the associated key or / and by different axial position of a driving stop on the respective axial sliding element.
  • the locking cylinders according to the invention are used in the assembly of locking systems, it is provided that at least one of the locking cylinders of the locking system and its secret-adapted key differs from at least one other locking cylinder of the locking system and its secret-adapted key at least by the design according to the invention.
  • locking systems can be constructed from a plurality of locking cylinders according to the invention in such a way that at least one of these plurality of locking cylinders differs from at least one other of this plurality of locking cylinders at least by different axial positions of the driving surfaces of their associated secret-adapted keys or / and different axial positions of the driving stops acted upon by these driving surfaces, with the axial sliding element in a more secure locking cylinder with associated parent key permits the shift of the tumbler pin in a narrower axial release position range and the axial slide element permits the shift of the tumbler pin in a lower axial lock cylinder with the associated subordinate key in a larger axial release position range.
  • the invention also relates to a key suitable for use in lock cylinders according to the invention provided with a level-varying control path running approximately parallel to the axis of rotation in at least one key side surface, insofar as the driving surface of the key extends from the end pointing towards the key tip to an end extending from this end to the key tip Longitudinal groove is formed in a key side surface, in particular if this longitudinal groove is arranged in the key side surface having a control path. It was pointed out above during the treatment of the locking cylinder which security-related advantages result from the fact that the driving surface of the key is formed by the end of a longitudinal groove running towards the key tip.
  • the invention further relates to a method for producing a combination of a lock cylinder according to the invention and an associated secret-adapted key.
  • the method according to the invention provides that, after the presence of a locking cylinder with a predetermined locking position of the axial sliding element and a predetermined position of the driving stop, a key blank adapted to the profile is provided with a longitudinal groove whose one end remote from the key tip acts as a driving surface for interacting with the driving stop serves such that after the key has been fully inserted into the key channel, the axial sliding element is in the release position. If one speaks here of the "presence of the locking cylinder", this does not necessarily mean that the locking cylinder must be physically present. It can also only exist in planning documents.
  • the key blank can then be further processed by providing it with the level sink (s) in the area of a longitudinal zone suitable as a control path, by providing notches in the key face and by milling longitudinal grooves determining the profile.
  • a lock cylinder housing is designated by 10.
  • This lock cylinder housing has a cylinder core receiving bore 12, the peripheral surface of which is designated 12a.

  • the tumbler pin 30 is, as already described above, by the cam-like interaction of the spherical pin end 30b with the Recess 12b pressed radially inward into the level depression 32f of the key shaft 32b.
