  • Such a locking cylinder is known from DE-A-25 46 550. Reference is made there in particular to FIG. 6.
  • the key shaft is assigned essentially the entire height of a central plane common to the back profile area and the chest profile area.
  • the notches are cut in the breast near-profile region so as to enclose the locking row of a 90 o angle different. This angle can vary. This should make it difficult to imitate the key on known copying machines.
  • used longitudinal groove profiles should be able to be used again practically by the inclination of the key shank in relation to the tumbler level.
  • the invention is based on the object of specifying a locking cylinder which opens up further possibilities for individualizing locking cylinders and associated keys against one another using a predetermined profile with longitudinal ribs and / or longitudinal grooves.
  • the respective amount of the angle can be varied, but care should be taken that the angle difference between mutually adjacent angle values is at least approximately 5 ° in order to rule out the risk that a user might force a key into the key channel of an unrelated one Tried to insert the lock cylinder.
  • the amount of the acute angle can vary, for example, between approximately 5 ° and approximately 16 °, wherein three different angle values can preferably be selected within this range.
  • the angle value 0 is also available for individualization, at which the mid-level near the chest and the mid-level near the back coincide.
  • Another individualization option is to design the individual ribs and grooves with different cross-sectional dimensions in the direction parallel to the respective central plane and perpendicular to the respective central plane for a given basic profile.
  • a particular advantage of the design of a locking cylinder and the associated key according to the invention is that a basic profile, once recognized as advantageous and determined by the arrangement and cross-sectional shape of its ribs and grooves, enables a very large number of locking variations, both for individual locking and for locking as part of locking systems.
  • the invention further relates to a group of lock cylinders, each with a key
  • the Key shaft is designed with a shaft profile having a chest edge surface, a back edge surface and side surfaces, at least one of the side surfaces being profiled by longitudinal ribs and / or longitudinal grooves

  • the lock cylinder core has core pin bores for receiving core pins, which core pin bores in a basic rotational position of the cylinder core (key insertion position and key removal ) aligned with the housing pin holes, the key channel and accordingly also the
  • one of the sub-groups can be used for one locking system.
  • the individual locking systems can then be varied in the usual way by modifying the respective basic profile, ie by changing the rib depth and width or the groove height and width in each case in a plane orthogonal to the axis of the locking shaft and / or by different notch arrangement.
  • An even larger number of closure variations can be obtained by providing an upper group of previously described groups, the individual groups differing from one another in terms of the amount of angle values of the acute angle + ⁇ or - ⁇ .
  • Applied to locking systems one can in particular proceed in such a way that, for example, a locking system is assigned a specific sub-group with a specific angle value. If locking systems do not have a large number of individual locking cylinders and associated bowls, you can also set up several locking systems with a subset of a predetermined angular value.
  • the angle difference between groups adjacent in terms of angular value amounts to at least approx. 5 °. If one again assumes that the angular values are to be varied between approximately 5 o and approximately 16 o , and further assumes that in order to avoid attempting to forcefully insert a specific key into a locking cylinder of an adjacent angular value, the angular distance is not should be smaller than 5 °, you can then provide at least three groups in an upper group.
  • a major advantage of the lock cylinder design according to the invention can also be achieved by a group of lock cylinders, each with a key, the key shaft of which is designed with a shaft profile having a chest edge surface, a back edge surface and side surfaces, at least one of the side surfaces being profiled by longitudinal ribs and / or longitudinal grooves,
  • the respective lock cylinder comprising a lock cylinder housing with a cylindrical housing bore and a cylinder core with a core axis rotatably accommodated in the housing bore and a key channel which runs essentially parallel to the core axis and is adapted to the shaft profile, wherein the lock cylinder housing has in at least one tumbler plane approximately containing the core axis substantially radially to the core axis housing pin bores for receiving radially inwardly spring-loaded housing pins of tumbler pin pairs and the lock cylinder core has core pin bores for receiving core pins, which core pin bores in a basic rotational position of the cylinder core (key insertion position and key removal ) align
  • the locking cylinders of a locking system can each be assigned to a sub-group, wherein - particularly in the case of a small locking system - several locking systems can also be accommodated within a sub-group.
  • the individualization between individual locking cylinders of a locking system can in turn take place by varying the cross-sectional dimensions of the ribs and grooves forming the basic profile and / or by means of different notches.
  • the invention relates to a method for producing locking cylinders, each with a key
  • the Key shaft is designed with a shaft profile having a chest edge surface, a back edge surface and side surfaces, at least one of the side surfaces being profiled by longitudinal ribs and / or longitudinal grooves
  • the respective locking cylinder comprising a locking cylinder housing with a cylindrical housing bore and a cylinder core with core axis and rotatably accommodated in the housing bore a key channel running essentially parallel to the core axis and adapted to the shaft profile

  • the lock cylinder core has core pin bores for receiving core pins, which core pin bores in a basic rotational position of the cylinder core (key insertion position and key removal ) aligned with the housing pin holes, the key channel and accordingly also the key
  • This method can be expanded further in that a plurality of groups are produced within the overall production of these locking cylinders, which differ from one another by different angular values + ⁇ or - ⁇ .
  • the invention relates to a method for producing locking cylinders, each with a key, the key shaft of which is designed with a shaft profile having a chest edge surface, a back edge surface and side surfaces, at least one of the side surfaces being profiled by longitudinal ribs and / or longitudinal grooves, the respective locking cylinder comprising Lock cylinder housing with a cylindrical housing bore and a cylinder core rotatably received in the housing bore with a core axis and a substantially parallel to the core axis, key channel adapted to the shaft profile, wherein the lock cylinder housing has in at least one tumbler plane approximately containing the core axis substantially radially to the core axis housing pin bores for receiving radially inwardly spring-loaded housing pins of tumbler pin pairs and the lock cylinder core has core pin bores for receiving core pins, which core pin bores in a basic rotational position of the cylinder core (key insertion position and key removal ) aligned with the housing pin holes, wherein the key channel and accordingly also the key shaft each
  • At least two sub-groups are produced as part of the overall production of these locking cylinders, where in the subgroups the side surfaces are basically the same, possibly due to cross-sectional variation of the Longitudinal ribs and / or longitudinal grooves have varied basic profiles and the acute angles between the median plane near the back and the tumbler plane are the same in terms of sign and amount in the individual subgroups and are also alike in amount from subgroup to subgroup.
  • the key handle part and the key shaft part can each be manufactured and connected to one another, for example by soldering or welding. This method, which appears complex at first glance, has in the case of the invention Design of the key has the advantage that the transition between the angled key shaft and the handle part can be obtained with high accuracy, without having to carry out complicated milling operations and without the need for expensive stamping tools. However, it should also not be excluded that the transition between the key shaft and the key handle part is obtained by stamping or milling.
  • the key handle part is preferably plane-parallel.
  • the key handle part is made in one piece with the key shaft part.
  • the handle part in addition to making the transition by milling or embossing, you can also remember that the handle part is crossed over the shaft part.
  • a stop surface can be obtained which, when the key is inserted into the key channel, defines exactly the position in which the notches of the key shaft interact properly with the radially inner ends of the core pins, regardless of whether the notches themselves are provided with sharp transitions at their roots or with continuous transitions.
  • the key grip part be set with a central part of the grip part essentially parallel to the middle plane close to the chest. Then it is achieved that the key handle part assumes a vertical position with its central plane if - as is usually the case - the tumbler plane and thus the central plane near the chest are aligned vertically.
  • the invention relates to a set of key pre-blanks for locking cylinders of the type explained above which are not yet profiled on the side surfaces.
  • This set comprises a plurality of pre-blank types, which differ from one another in terms of sign and / or magnitude different angular values of the acute angle between the median plane near the back and the median plane near the chest.
  • Such a set of non-profiled key pre-blanks can be kept available, for example, in the manufacturing company in which both keys and locking cylinders are manufactured. In this way, the storage in the manufacturer's key and lock cylinder is facilitated, especially when the amounts of the angular values are graded in a predetermined manner. This also simplifies production, warehousing and sales for the manufacturer of key blanks, which does not manufacture locking cylinders at the same time.
  • the invention relates to a set of key blank blanks for locking cylinders profiled on the side surfaces of the type explained above.
  • This set comprises a plurality of intermediate blank types, possibly different rib and or groove dimensions, which differ from one another by sign and / or magnitude different angular values of the distinguish acute angle between the median plane near the back and the median plane near the chest.
  • This reduces the manufacturing effort and storage for the manufacturer of locking cylinders and associated keys and also for the manufacturer of intermediate blanks.
  • the supply and inventory of intermediate blanks is reduced for the locksmith, which can only be achieved by milling notches on the need to be adapted to each individual locking cylinder.
  • the invention relates to a key intended for a lock cylinder, in particular a lock cylinder according to the invention described above, the key shaft of which is designed with a shaft profile having a chest edge surface, a back edge surface and side surfaces, at least one of the side surfaces being provided by longitudinal ribs and / or longitudinal grooves is profiled, the key shaft also having a profile area near the chest with a middle plane near the chest and a profile area near the back with a center plane near the back, with notches being machined further into the profile area near the chest.
  • the invention includes at such a key, the breast close to the center plane with the back near the center plane an acute angle which is preferably about 5 to about 16 o o is.
  • the line of intersection of the middle plane near the chest and the middle plane near the back can be offset, preferably slightly, with respect to the base of the notch of the notch cut deepest in the chest edge surface toward the back edge surface.
  • the cutting line can lie in the region of the base of a longitudinal groove. It is advantageous if the cutting line lies in a middle height range of the shaft profile, preferably in a region whose border near the back of the back edge surface and the breast near border of the chest edge surface each about 30% of the total height of the shaft profile undamaged by notches.
  • the notches can preferably be delimited by notch surfaces, which are preferably essentially orthogonal to the middle plane near the chest.
  • the invention further relates to an intermediate blank for a key of the type described, with the respective key profile and handle part which can be derived therefrom, and with a notched chest edge surface.
  • intermediate blanks can form an intermediate blank set for the manufacture of a key set.
  • the invention relates to a pre-blank for the production of an intermediate blank of the type described and a set of pre-blanks for the production of a set of such intermediate blanks, the pre-blanks being designed with the intermediate blank derived therefrom having a corresponding shaft envelope profile and, if desired, also a grip part, the side faces of Longitudinal grooves and longitudinal ribs are free and the chest edge area is free of notches.
  • FIG. 1 you can see a lock cylinder housing 10 with a cock profile.
  • This lock cylinder housing 10 has a cylindrical housing bore 12, on the inner circumferential surface of which a cylinder core 14 is rotatably mounted.
  • the axis of the cylinder core 14 is designated A, it is also the axis of the housing bore 12.
  • a key channel 16 is incorporated into the cylinder core 14 along the axis A, which receives a key shaft 18s.
  • the key shaft 18s has a back edge surface 18a, a chest edge surface at the level 18b and two side surfaces 18c and 18d.
  • the back edge surface 18a lies against the inner peripheral surface 12a of the housing bore 12.
  • the pectoral surface at level 18b faces a series of tumbler pin pairs, which are arranged one behind the other in a tumbler plane Z perpendicular to the plane of the drawing.
  • Notches 20 are cut into the breast edge surface 18b in the direction perpendicular to the plane of the drawing, only one of which is shown in FIG. 1.
  • Each notch 20 works with one Tumbler pin pair 22 together, each tumbler pin pair 22 consisting of a core pin 22a and a housing pin 22b.
  • the core pin 22a is received in a core pin bore 24a, while the housing pin 22b is received in a housing pin bore 24b.
  • the housing pin 22b is biased in the direction of the axis A by a helical compression spring 26.
  • the upper end of the core pin 22a engages in the notch 20. If a key 18 adapted to the locking secret of the locking cylinder is inserted, the notch 20 is matched to the tumbler pin pair 22 such that when the upper end of the core pin 22a is immersed in the notch 20, the contact surface 28 between the core pin 22a and the housing pin 22b coincides with the separating surface 12a between the cylinder core 14 and the housing bore 12, ie coincides with the inner circumferential surface 12a of the housing bore 12. This then applies to all notches 20 and associated tumbler pin pairs 22. It is clear that then and only if all contact surfaces 28 with the separating surface 12a coincide, the cylinder core can be rotated.
  • the key 18 can only be inserted and removed when the core pins 22a and the housing pins 22b lie together in the tumbler plane Z, because only when the key is inserted and when the key is removed between successive notches 20 can existing projections slide over the tumbler pin pairs 22 by pressing the tumbler pin pairs 22 downward against the action of the associated spring 26.
  • a key area 18 can be distinguished from a breast area B with a middle plane BM close to the chest and a back area R with a middle plane RM close to the back.
  • the middle plane BM close to the chest and the middle plane RM close to the back form an angle ⁇ with one another a, which is denoted by - ⁇ in accordance with the usual counting in a Cartesian coordinate system in FIG.
  • the kink K lies in the middle height range of the profile of the key shaft 18s, for example in an area whose back and chest boundaries from the back edge surface 18a and the chest edge surface 18b are each approx. 30 % of the total height of the notched profile of the shaft 18s.
  • the locking cylinder according to FIG. 2b designated there in the front view, corresponds to that according to FIG. 1.
  • the key shaft is not shown in FIG. 2b.
  • the ribs intended and adapted to engage in the grooves of the key shaft 18s are designated M1R-M4R or N1R-N2R.
  • FIGS. 2b and 2a Let us now compare FIGS. 2b and 2a. It can be seen that the distribution of the ribs M1R-M4R and N1R-N2R in the two different locking cylinders according to Figures 2b and 2a is identical. The difference between Figures 2b and 2a is that - again under On the basis of the angular count in a Cartesian coordinate system - the angle between the middle plane near the chest BM and the middle plane RM near the back in FIG. 2a is + ⁇ . It follows that while maintaining the same side surface profiles defined by the ribs M1R-M4R and N1R-N2R, two different shaft profiles are available.
  • shaft profiles can be varied further by varying the width and / or the depth of the ribs M1R-M4R and N1R-N2R in one or more stages.
  • a first subgroup of locking cylinders is available according to FIG. 2a, the locking cylinders within this group being able to differ in terms of the width and / or depth of the ribs M1R-M4R and N1R-N2R.
  • the subgroup according to FIG. 2a can thus be used, for example, to set up a hierarchical locking system.
  • the superordinate key can be inserted into all subordinate locking cylinders, while conversely the keys of the subordinate locking cylinders cannot be inserted into a superordinate locking cylinder, the key channel of which is completely filled by the superordinate key, because the grooves of these subordinate keys are less wide and / or less are deep than the grooves of the parent key.
  • the angles + ⁇ and - ⁇ can be varied in steps in Figures 2a to 2b.
  • the amount of the angle + ⁇ or of the angle - ⁇ is at least 5 ° and at most 16 °.
  • three gradations are possible for the respective amount of the angular value. The gradations are selected so that it is not possible to insert a key with a predetermined angle value + ⁇ or - ⁇ into a locking cylinder whose angle value + ⁇ or - ⁇ corresponds to the next step.
  • FIG. 2c you can see a locking cylinder, which is derived from the locking cylinder according to Figure 2a in that it is mirrored together with the associated ribs with respect to the tumbler plane Z, so that again the negative angle value - ⁇ between the central plane RM close to the back and BM near the chest.
  • an expanded sub-group can be formed by varying the width and / or depth of the ribs M1R-M4R and N1R-N2R or the grooves M1-M4 and N1-N2.
  • the angle value - ⁇ gain approximately between -5 ° and -16 ° subgroups within which further individualization is possible by varying the grooves or rib dimensions.
  • the lock cylinder type according to FIG. 2d is in turn derived from the lock cylinder type according to FIG. 2b by mirroring with respect to the tumbler plane Z. What has been said in relation to FIG. 2c applies to the formation of subgroups and subgroups.
  • Figures 2a-2d each represent the basic profile of a subgroup, with the subgroups being maintained by maintaining the respective angle + ⁇ or - ⁇ and the respective basic profile by differently dimensioning the ribs in the locking cylinder and the grooves in Key can be expanded. These subgroups together form a group.
  • Each individual of the lock cylinder types according to FIGS. 2a-2d and the associated key can be subdivided into subgroups which differ from one another only by differences in the amounts of the respective angles. In each of these subgroups, an expansion is again possible by varying the widths and / or depths of the ribs or grooves.
  • the line scale SK further indicates that the depth of the notches (see notch 20 in FIG. 1) is gradual, but if desired also continuous can be varied. The gradual variation of the notch depths is preferred, however, because it reduces the number of tumbler pin pairs that are necessarily to be kept in stock.
  • the locking cylinders described so far can in principle also be combined with springless additional locking pins, locking pins and blind pins, as are shown and explained in German patent 31 23 511. Reference is made in detail to this patent specification for disclosure. Furthermore, the locking cylinders according to the invention can also be combined with locking levers, as shown and described in detail in European Offenlegungsschrift 0 237 799.
  • FIG. 3 shows a key which corresponds to the locking cylinder according to FIG. 2d.
  • an edge 30 can be formed at the transition between the key shaft 18s and the key handle 18g, for example by embossing the key or by milling the key or by assembling the key from separately manufactured parts 18s and 18g.
  • This edge 30 can be used to stop on the end face ST of the lock cylinder core (see FIG. 2d) and thus to determine the insertion position of the key shaft in the key channel, in which the contact surfaces 28 all coincide with the separating surface 12a.
  • notch flanks are schematically indicated by 32 and 34, which are preferably, but not necessarily, perpendicular to the middle plane BM close to the chest.
  • invariant profile areas in the subgroup or subgroup. These invariant profile areas can be formed, for example, by the lowest partial area of the profile area B close to the chest and the uppermost partial area of the profile area R close to the back.
