It is an object of the present invention to provide a lock core, a lock cylinder, a lock device, a key and a cylinder lock, and methods therefor, wherein a lock core or cylinder core is variably codable for a plurality of key variants.

These and other objects are achieved by a lock core, a lock cylinder, a key, a locking device and a cylinder lock and method for this purpose.

Advantageous developments of the invention are indicated in the dependent claims or are given below in connection with the description of the figures.

The invention includes the technical teaching that in a lock core for a lock cylinder, comprising a locking profile having a closing channel, wherein the closing channel at least partially delimiting locking profile, in particular the closing channel at least partially laterally delimiting locking profile is defined or defined by profile-giving profile elements provided is that at least one profilgebendes profile element fixed, that is integrally formed with the lock core and at least one variable profile element is separately and / or releasably formed to the closing channel, a base portion of the lock core and / or the lock core, so that the closing profile by an exchange the at least one separate profiling variable profile element is changeable, in particular chip-free changeable, wherein the at least one separate variable profile element as a about a profile element axis rotationally symmetrical Profilk body is formed.

The lock core has a closing channel. The closing channel is profiled. In this case, the closing channel profile is partially defined by an integrated in the lock core, that is, in one piece with the lock core, trained basic profile. This basic profile is fixed, for example, with cutting process, set in the lock core. In addition, the closing channel profile or closing profile is formed by at least one exchangeable or deployable variable profile elements. The variable profile element is manufactured separately from the lock core. With at least a portion or part of the variable profile element protrudes into the closing channel, so that the projecting into the closing channel part or portion forms a part of the closing profile. The closing profile is thus formed by fixed and separate or variable profile elements. The at least one separate variable profile element is designed as at least about a profile element axis rotationally symmetrical body. Preferably, the variable profile element is substantially cylindrical, possibly formed with radial projections and / or grooves. By a rotationally symmetrical design, the production of the separate variable profile elements is easier and insertion of a key in the lock channel is smoother. The profile body may be formed, for example, as a profile pin and / or profile role. Preferably, a plurality of variable profile elements are provided.

To limit the number of matching profiled keys, the lock core on a closing channel, which is preferably bounded laterally by a closing profile. The closing channel is formed as a groove or slot in the lock core and has at least in the raw state a basically cuboid basic shape. In this case, the closing channel is bounded laterally by two side walls and a bottom wall of the lock core. In a fourth direction, preferably in the side of the bottom wall designed as a narrow side, the closing channel is open. While the bottom wall has passages for locking pins, the side walls are profiled by profiling elements, so that the closing profile of the closing channel is provided. In one embodiment, as a reversible key suitable lock core, the tumbler pins penetrate a side wall of the closing channel. Conventional or conventional closing profiles, keys, lock cores, lock cylinders, etc. are understood to mean those which, when installed, are designed for the insertion of a key in a substantially vertical direction. The reversible key can be rotated 180 ° into the lock core. The permutation for the scanning by Zuhaltestifte or the Bohrmulden at a reversible key is located, inter alia, on the broad side of the key shaft. In a conventional key, these are usually on a narrow side of the key shaft.

The closing profile can be formed at least partially by cutting introduced into the lock core profile elements such as recesses, projections and the like, thus by solid or firmly formed in the lock core profile elements. These are formed integrally with the lock core. Furthermore, the closing profile has at least one exchangeable variable profile element. The closing profile is thus defined by at least one exchangeable profile-giving variable profile element, preferably by a plurality of interchangeable profiling variable profile elements. In contrast to the prior art, in which the profile elements exclusively produced as machined or integrally formed with the lock core projections and recesses fixed to a part of the lock core are formed, for example, by broaching, milling or other cutting manufacturing process, or by exclusively interchangeable, separate variable profile elements, in the inventive solution at least one profilgebendes variable profile element is interchangeable, that is formed as a separate part and releasably connected to the lock core and at least one Profile element firmly, that is integrally formed and not interchangeable in the lock core. In contrast to closing profiles formed exclusively with separate, detachable profile elements, a closing profile with integrated and separate variable profile elements offers improved codability, since a higher number of closing profiles can be realized. Because exclusively realized with separate variable profile elements closing profiles are to be arranged at least in conventional keys in the range of Zuhaltestifte. Thus, in the solution according to the invention, there is no collision of locking pins and profile elements.

The profiling variable elements can be manufactured separately, without the lock core must be present in the production. In one embodiment, at least one fixed profile element is machined into the lock core or integrally formed with the lock core and at least one variable profile element is interchangeable. In this way, a closing profile with fixed and exchangeable variable profile elements is formed.

A further embodiment provides that at least one - fixed or variable - profile element in the closing channel forms an undercut. By a combination of separate variable profile elements and at least one solid profile element forming an undercut, a higher closing security can thus be achieved.

In one embodiment it is provided that at least one profile element receptacle is formed in the closing core adjacent to the closing channel, wherein the profile element receptacle has at least one opening to the closing channel, so that a profile-forming variable profile element accommodated in the profile element receptacle protrudes at least partially into the closing channel. The profile element receptacle is provided for receiving a variable profile element. Preferably, a profile element receiving substantially as a groove or slot in the corresponding, the closing channel laterally bounding side wall of the lock core is formed. The profile element receptacle in this case has a groove-shaped section or part and a stepped bore section or stepped bore part. The groove-shaped portion may be formed by inserting a bore with a portion of the bore wall removed. Preferably, the stepped bore portion is formed in the region of the bottom wall of the closing channel or protrudes into the bottom wall. The groove-shaped or slot-shaped section, that is to say the section of the openings into the closing channel, adjoins it and extends in the direction of the opening of the closing channel in the radial direction of the closing core. Preferably, the profile element receptacle is formed by means of drilling or drilling. In this case, the bore radially penetrates the locking core to a greater extent than the closing channel, so that the substantially groove-shaped shape results with the adjacent stepped bore portion. The profile element receptacle is thus substantially cylindrical or half or three quarters cylindrical. Other embodiments such as cuboidal shapes or oval, triangular, quadrangular, polygonal or any other cross-sectional shapes of the profile element receptacles are possible. However, the cylindrical embodiment is preferred, since it can easily be introduced by drilling into the lock core. Complementarily, the at least one profiling variable profile element has at least sections of a corresponding shape or contour. In this case, at least one portion is formed complementary to the profile receiving, so that the variable profile element rests against the wall of the profile recording. Preferably, the portion of the variable profile element, which is provided for receiving in the Stufenbohrungs- or blind hole portion corresponds to the contour of the stepped bore portion, so that a suitable storage is realized. Correspondingly, a cylindrical end section of the variable profile element corresponds to the cylindrical stepped bore section of the profile receiver. A closing profile is thus at least partially formed by a flank or the lateral contour of the variable profile element. In other embodiments, the profile element receptacle may be formed as a bore, wherein the bore end - with or without previous lateral breakthrough to the closing channel - opens into the closing channel. In this way, a closing profile can be formed by one end of a variable profile element which projects into the closing channel.

In one embodiment, it is provided that the lock core has at least one receptacle, preferably a plurality of receptacles for tumbler pins and at least the alignment of a receptacle for the tumbler pins and the alignment of at least one Profilelementaufname and thus also the recorded variable profile element or Zuhaltestiftes transversely and / or non- are formed parallel to each other, in particular formed perpendicular to each other. In this way, it is easy to provide a lock core for a conventional or conventional key

A further embodiment provides that the lock core has at least one receptacle, preferably a plurality of receptacles, for tumbler pins and at least the alignment of a receptacle for the tumbler pins and the alignment of at least one profile element receptacle and thus also of the recorded profile element are formed transversely and / or parallel to each other. The tumbler pins are designed to sense the permutation - the cuts - on the key shank and allow for rotation when the length of the tumbler pins and the depth of the grooves match, thus forming a parting plane. Usually, a plurality of tumbler pins are provided, which are aligned the same. In one embodiment, the alignment of the tumbler pins is aligned transversely, in particular perpendicular, to the orientation of the profile elements or profile element receptacles. In one embodiment, at least the orientation of a tumbler pin and a profile element is the same. In one embodiment, the orientations are transversely or at an angle to each other, in particular aligned perpendicular to each other. In conventional or conventional keys, the tumbler pins protrude through a closing channel bottom of the lock core in the direction of the closing channel. The tumbler pins and the associated Zuhaltestiftaufnahmen are thus arranged or aligned correspondingly substantially perpendicular to a closing channel bottom or parallel to the closing channel walls. In another embodiment, the tumbler pins protrude through a closing channel wall of the lock core in the direction of the closing channel. The tumbler pins and the associated Zuhaltestiftaufnahmen are thus arranged or aligned correspondingly substantially perpendicular to a closing channel wall or parallel to the closing channel bottom. The profile element receptacles are formed in an embodiment parallel alignment of the receptacles laterally offset from the Zuhaltestiftaufnahmen so that the images are not coaxial with each other. As a result, an overlap and thus a coding restriction is avoided. Preferably, the maximum diameter of the variable profile elements are formed smaller than the maximum diameter of the tumbler pins. In a further embodiment, the length of the variable profile elements in their main extension direction or in the axial length is less than the diameter of the lock core, so that an overlap with the engagement portion of the tumbler pins is avoided. The profile element receptacles are preferably introduced from one side into the lock core. The Zuhaltestiftaufnahmen are preferably introduced from another side in the lock core. In this case, the orientation of the profile element receptacles can be aligned in the same direction as the orientation of the Zuhaltestiftaufnahmen. In particular, in an embodiment of the lock core for a reversible key, the orientation of the profile elements or the profile element receptacles is transversely, preferably perpendicular to the orientation of the tumbler pins or Zuhaltestiftaufnahmen.

In one embodiment, the variable profile elements and correspondingly the profile element receptacles are arranged or provided only on one side of the closing channel, thus adjacent to only one side wall of the closing channel. In another embodiment, the variable profile elements and profile element receptacles are provided on both sides of the closing channel. In one embodiment with profile elements arranged on both sides, the profile elements are formed opposite one another as profile element pair. In another embodiment, the profile elements are arranged offset from each other in two-sided arrangement, in particular longitudinally and / or transversely offset.

In a preferred embodiment, the orientations of the tumbler pins or the Zuhaltestiftaufnahmen and the variable profile elements or the profile element receptacles are designed differently from each other.

In a further embodiment it is provided that at least one profile-giving variable profile element is designed as a profiled profiled profiled element which has at least two different radial or lateral or lateral dimensions over an extension direction or also in the axial or longitudinal direction. The respective variable profile element can have any desired contour, which then defines the closing profile. Thus, the outer contour of the variable profile element forms a kind of control curve. In particular, in a direction transverse to the extension direction of the closing channel, in particular perpendicular thereto, has a variable profile element at least two different sections with different extension transversely or perpendicular to the Schließkanalerstreckung so that they to a different extent in the closing channel or more precisely the machined closing channel or Rough closing channel protrude. The at least one variable profile element is preferably designed as an elongated body. This has a main extension direction, which is also referred to as the axial direction of the variable profile element. Laterally, the dimensions of the body vary, so that any profile can be realized. The variation can be continuous or discontinuous, thus erratic. Corresponding thereto and / or complementary thereto, in one embodiment, at least in sections, the profile of the profile element receptacle also varies. In one embodiment, the variable profile element is not rotationally symmetrical. In a preferred embodiment, the variable profile element is rotationally symmetrical. The variable or the solid profile element preferably has one Base portion from which projections, recesses, notches, slots, grooves, ribs, curves or the like are formed laterally, so as to form the profiling contour of the variable profile element. The transitions between the different lateral dimensions of the variable profile element are continuous in one embodiment, so that the contour of the variable profile element forms a kind of control curve. In a preferred embodiment, the transitions are discrete or discontinuous or even jumped, for example by heels. In a preferred embodiment, the variable profile element is cylindrical with a plurality of cylinder sections. The cylinder sections have different diameters and / or different widths in the axial direction. The cylinder sections are preferably arranged coaxially to one another, but in other embodiments may also be formed eccentrically relative to one another at least in pairs. An outer contour of the variable profile element may vary from section to section. The variation may be provided in one or more directions. The contour can describe a wide variety of curves or general contour curves. Preferably, the contour is linear, preferably so that a cylindrical portion is annular or circular disk-shaped. In cross section or in another direction, an embodiment provides that the contour or the profile or the profiling of the closing channel and / or the profile elements according to a sawtooth curve, a V-curve, a circular curve and / or a mathematical curve such as a trigonometric Curve, a polynomial curve, an exponential curve, a Hype curve, a logarithm curve, a hyperbolic curve, a parabolic curve, a potential curve and the like, at least partially formed. In this embodiment, the respective profile element is provided mainly for a lateral intrusion into the closing channel.

In yet another embodiment, it is provided that, preferably in the closing channel direction, a plurality of separate and / or detachable profiling variable profile elements are arranged at a distance from one another. In the closing channel direction, the direction of the main extension direction of the closing channel, ie the direction in which a corresponding key is guided into or pulled out into the closing channel, means here. Preferably, the profile elements are arranged one behind the other in the direction of the extension direction of the closing channel. In this case, in one embodiment, the profile elements are uniformly spaced from each other. In another embodiment, the profile elements are at least partially spaced non-uniformly. Accordingly, the profile recordings are designed to. The profile recordings are the same or equidistant from each other with remaining between the profile recordings webs and / or are different from each other spaced in Schließkanalrichtung. At least two profile elements and / or correspondingly also profile element receptacles can be arranged offset from one another, in particular in the direction transverse, preferably perpendicular to the closing channel direction, thus in the radial direction. Preferably, the profile receptacles are formed in the radial direction with the same longitudinal dimension. The profile elements are preferably formed in one piece. The at least one variable profile element and the associated profile element receptacle are designed so that at least one section laterally beyond the profile element receiving, which also forms the side wall of the closing channel, more precisely the Rohschließkanals protrudes, thus forming a profile for the Rohschließkanal. Since the profiled closing channel is also formed by the exchangeable profile elements, the closing channel without the variable profile elements and / or the profile element receptacles is also referred to as a raw closing channel. The Rohschließkanal may in one embodiment, the unchangeable profile elements which are integrally formed with the lock core have, so already be partially profiled. In another embodiment, at least two variable profile elements can be arranged offset from one another and / or rotated relative to one another. The length of at least two, preferably all, variable profile elements is the same in one embodiment.

In a further embodiment it is provided that at least one of the separate variable profile elements is designed as a profile pin and / or profile roller, which projects with one end or which with a flank for profile formation in the closing channel. In one embodiment, all separate profile elements are designed as a profile roll. The profile rollers themselves can be designed differently. In a further embodiment, all profile elements are designed as profile pins, wherein the profile pins themselves may be formed differently from each other. In a preferred embodiment, at least one profile element is designed as a profile roller and a profile element as a profile pin. In this way, the profile elements can be accommodated differently and thus save space in the lock core. In addition, an improved coding or scanning can be realized. When designed as a profile roller, the variable profile element projects laterally, thus with a flank, into the closing channel and thus defines the closing profile. In the profile pin protrudes one end of the profile element in the closing channel, thus defining the closing profile. In contrast to the locking pins, the profile elements are not axially displaceable, in particular not resiliently axially displaceable. Preferably, the length of the profile elements corresponds to the length of the associated Profile element receptacles. In another embodiment, the profile elements are mounted axially displaceable, in particular resiliently displaceable axially.

In yet another embodiment it is provided that at least one variable profile element, preferably a plurality of variable profile elements and most preferably all variable profile elements, are rotatably arranged in the corresponding profile element receptacle. The individual sections, preferably cylindrical sections, are integrally formed in one embodiment. In another embodiment, the individual sections are designed in several parts. The dimension of at least two sections is formed differently, wherein a difference by material, coating, diameter or radial dimension, width or axial dimension, surface procurement and / or the like may be formed. In particular, two sections of the respective profile element are rotationally symmetrical and corresponding to the respective diameters of the profile element receptacle, so that the profile elements are thus mounted on at least two locations in the profile element receptacle. Corresponding to the profile element receptacles are formed. The profile element receptacle can follow the contour of the profile element over its entire main direction of extension, so that the variable profile element rests against the wall of the profile element receptacle via the main extension direction. Preferably, the contour of the profile element receiving only partially corresponds to the contour of the profile element, so that in sections, a free space between the outer contour profile element and the wall profile element recording is available. The profile element receptacle is designed as a stepped bore in one case, preferably as a stepped bore, in which the diameter of the stepped bore sections becomes smaller in the direction of the closing channel. By a rotatable mounting a frictional resistance is reduced upon insertion of a key in the closing channel. In addition, the variable profile elements wear more evenly due to the rotatable arrangement, whereby a life of the variable profile elements and thus also of the lock core is increased. Preferably, the lock core has no fixing means for preventing rotation of the profile elements, is thus formed free of fixatives.

Accordingly, it is provided in one embodiment that at least one variable profile element as a rotation axis with at least two mutually spaced in the extension direction radial projections, in particular rotationally symmetrical cylindrical radial projections, is formed. As described, the variable profile element can be formed in one piece or in several parts. The variable profile element may have rotationally symmetric and non-rotationally symmetric sections. Thus, the profile element receiving projections, recesses, ribs, notches or the like, which can then serve for fixing the position of the profile elements at least in the main extension direction of the profile elements / profile element recording - radial direction of the lock core. The profile elements would then not have to extend over an entire length of the profile element receptacle and bear against the ends of the profile element receptacle, but could be mounted on a spaced from the ends of the profile element recording Anformung that engages between two sections of the profile element, and fixed in the axial direction.

An embodiment provides that at least one variable profile element has a contour and / or a contour profile or a profile or a profiling, in particular an outer contour or an outer contour profile which is selected from the group of gradients comprising linear courses, sawtooth curve courses, V-curve curves, circular curve curves, mathematical curves such as trigonometric curves, polynomial curves, exponential curve curves, Hypekurvenverläufe, Logarithmuskurvenverläufe, Hyperbelkurvenverläufe, Parabelkurvenverläufe, Potentialkurvenverläufe and the like.

The key has a key profile. This is designed so that the key with the key shank can be plugged into the appropriate closing channel. For this purpose, the key shank has a key profile which is at least partially complementary to the closing profile. The key profile is also formed by profile elements. In particular, the key profile is formed by integrally formed with the key shank profile elements such as projections, grooves, notches, hollows, recesses and the like. The outer contour of the key profile, in particular the outer contour of the profile elements or the profile or the profiling is formed in sections as a curve. The curve is formed analogously to the curve of the closing profile, for example as a mathematical function as a logarithmic Curve, exponential, sine, rectangular, triangular and the like formed.

The lock cylinder has a cylinder housing. In this a bore is introduced, which is corresponding to the outer contour of the lock core and which surrounds the recorded lock core fully. The bore is surrounded by a cylinder wall, which thus forms the cylinder housing in the region of the locking core. In this way, the closing channel is surrounded on its open side by the cylinder housing and is limited by this accordingly. The lock core is received in a bore of the cylinder housing and is surrounded by the cylinder wall or adjacent to this. There, this is preferably arranged by means of a clamping ring, in particular fixed axially. About the lock core and a coupling element is a coupling with a locking lug.

For the production of a corresponding lock core, the holes for the profile element receptacles are introduced radially in the lock core in one step, so that they pass through a central axis of the lock core. In a further step, the closing channel is introduced into the lock core so that it partially exposes the holes for the profile element receptacles or generates at least one opening to the holes. The order of introduction of the closing channel and the holes or profile element recordings can also be chosen vice versa.

The 1 to 28 show in different views and degrees of detail a closing unit or closing device 100 or their components.

1 shows schematically in a perspective view an embodiment of a closing device 100 with a lock cylinder 1 and a corresponding key 12 or also key unit. In the 1 is the lock cylinder 1 designed as a profile double cylinder. This includes a cylinder housing 2 , which consists of a respective cylinder opening exhibiting, circular in cross-section cylinder wall 4 and one of this radially outwardly uniform material web portion 5 composed. In each cylinder opening is a cylinder core or lock core 8th arranged, for example by means of a clamping ring 43 axially fixed (see 13 ). The cylinder wall 4 forms with its inner wall a core hole into which the lock core 8th is used. In the lock core 8th is a radial cut keyway 9 (please refer 2 ; here only schematically indicated) incorporated, the one side of the lock core 8th is open and with a longitudinal median plane of the web section 5 flees. In a known manner takes the lock core 8th at least two-part locking elements, tumbler pins, tumbler pins and / or housing pins 10 (see ua 20 ), which are in 1 are not explicitly shown and the key shaft side recesses of the key 12 be classified. The core-side ends of the in the direction of the keyway 9 spring-loaded tumbler pins 10 jam stop limited in the key channel 9 into it. Such tumbler pins 10 However, they are known so that they will not be discussed further. Around a rotation axis of the cylinder wall 4 , is in a recess 42 a closing unit 40 with a closing nose 41 (please refer 13 and 14 ). This is when turning a matching to the closing profile key 12 that is with a key 12 with corresponding key profile and to the tumbler pins 10 matching keyshaft side recesses rotated about the axis of rotation, thus realizing a closing function of the lock cylinder 1 which is well known. The key 12 has, among other things, a key shaft 12 ' on which the key profile and the permutation wells are formed.

2 shows schematically in perspective view the embodiment of the lock cylinder 1 to 1 without corresponding key 12 , Accordingly, the closing profile of the closing channel 9 to recognize more clearly. This has recesses, depressions and projections, on the one hand along a main extension of the closing channel 9 run and which are formed here by a median plane on both sides of the plane. Over the course along the main extension of the closing channel 9 the closing profile can vary.

3 shows schematically in a perspective view an embodiment of a lock cylinder 1 in which an upper cylinder wall section is removed. In this way, the closing channel 9 visible along its entire main extension. How out 3 can be seen, the lock core 8th next to the profiled closing channel 9 Profile element receptacles 140 on, in which separately trained, replaceable profile elements 130 are introduced or are introduced. The profile element recordings 140 are here as receiving holes 141 formed and cut at least partially the closing channel 9 so that the mounting holes 141 and the closing channel 9 partially overlap and so a common profile channel or a common closing profile is realized. In the mounting holes 141 are (here only partially) the profile elements 130 plugged in. These are designed so that these with a part in the closing channel 9 protrude and form part of the closing profile.

4 shows schematically in a partial exploded view of the embodiment according to 3 , Here is clearly the formation of the profile elements 130 and the profile element recordings 140 to recognize. The profile element recordings 140 are on both sides of the median plane of the closing channel 9 intended. In this case, a part of the mounting holes overlaps 141 with a part of the closing channel 9 , so each one breakthrough 145 between receiving bores 141 and closing channel 9 is trained. In the mounting holes 141 whose main extension is approximately parallel to the plane of the median plane ME of the closing channel 9 runs are the profile elements 130 plugged in or inserted. The profile elements 130 are here as rotationally symmetrical profile elements 130 , more precisely as profile rolls 137 formed with rotationally symmetrical cross-section. In this case, the cross section varies along an axis of the profile rollers 137 so that the profile elements 130 only intermittently or in sections into the closing channel 9 through the respective breakthroughs 145 protrude. The profile rollers 137 themselves are formed differently in pairs. Due to the different design of the profile rollers 137 Different closing profiles can be realized.

5 schematically shows a side view of the embodiment according to 3 with illustrated different view or cutting planes. A cutting plane AA passes through a remotest to a front or key insertion side of the lock core 8th approximately in the middle by the rearmost profile element holder 140 , A cutting plane A1-A1 runs approximately in the middle through the second frontmost profile element holder 140 , A cutting plane A2-A2 runs approximately centrally through the foremost profile element receptacle 140 , A view plane A3-A3 runs along a front side F of the lock core 8th ,

6 shows schematically the section AA of the embodiment according to 5 , The cylinder wall 4 of the cylinder housing 2 surrounds the lock core 8th full. In the lock core 8th are the closing channel 9 as well as on both sides of each a profiled element recording 140 in the form of a receiving bore 141 intended. This overlaps or overlaps part of the mounting hole 141 with the closing channel 9 so breakthroughs 145 are realized. The closing channel 9 itself has a lateral closing profile, which by projections or recesses in the direction of the two-sided profile element recordings 140 is formed. By inserting corresponding profile elements 130 in the profile element recordings 140 , as in 7 shown, can be realized as a complex, variable closing profile.

7 shows schematically the section A1-A1 of the embodiment according to 5 , In the profile element recordings 140 are different profile elements 130 in the form of profile rolls 137 added. The closing profile of the closing channel 9 varies over its main extension direction. Due to the different profile elements 130 In addition, a replaceable, variable closing profile section is formed. It is easy to see that the profile elements 130 partly in the side of the closing channel 9 through appropriate breakthroughs 145 protrude. By appropriately filling or releasing the breakthroughs 145 is next to a fixed or fixed profile section of the closing channel 9 implemented a variable profile section. The profile elements 130 are with an end portion in a corresponding portion of the profile element receptacle 140 stored as in detail view X ( 11 ) is described.

8th shows schematically the section A2-A2 of the embodiment according to 5 , Again, it can be clearly seen that the closing profile along the main extension direction of the closing channel 9 varied. In this way, a variable closing profile is realized. In detail view Y a part of the closing profile is shown enlarged.

9 shows schematically the view A3-A3 of the embodiment according to 5 , In 9 is the front F of the lock core 8th shown with a view in the main extension direction of the closing channel 9 , In this view is clearly the closing profile of the closing channel 9 to recognize. The closing profile 9 consists of a fixed, unchangeable part 9a and a variable, variable part 9b , The solid part 9a is due to the contour of the closing channel 9 self determined For this purpose, the closing channel 9 corresponding projections and recesses. These are during training or introduction of the closing channel 9 in the lock core 8th established. The variable part 9b is through the projections and recesses of the profile elements 130 - here the profile rollers 137 - formed, which from the profile element recordings 140 through the breakthroughs 145 in the closing channel 9 protrude laterally or do not protrude. Because the profile elements 130 interchangeable, can be the variable part 9b by exchanging the profile elements 130 change.

10 schematically shows a cross section through an embodiment of a lock core 8th before training profile element shots 140 , In the lock core 8th is the profile channel 9 brought in. This has the main extension direction in the direction of view. The center plane is marked ME , This extends radially to the lock core 8th and in the direction of view, ie in the main direction of extension. The closing channel 9 is groove-like in the lock core 8th introduced, making a breakthrough 8a on a circumference of the lock core 8th this results and the closing channel 9 forms a kind of groove or slot. The closing channel 9 according to 10 is still designed as Rohschließkanal, ie without providing profile element recordings 140 and profile elements 130 , The raw closing channel thus forms the fixed or tool-free invariable part of the closing channel 9 from, who may already have a machined introduced profile. The raw closing channel is preferably machined in the lock core 8th educated. The closing profile of the raw closing channel here has projections, ribs, recesses, grooves and the like. These are in 10 mirror asymmetric to the median plane ME educated. The present (fixed) closing profile of the raw closing channel has on both sides of the median plane ME two recesses, which are separated by a projection. The projections are each arranged so that a total of one closing channel 9 with a predetermined minimum width, in which a key remains 12 is insertable. The minimum width is required to have too thin key strengths and therefore a break in the key 12 to prevent. Preferred minimum closing channel widths are in the range of greater than or equal to 1 mm. In order to make the closing profile of the Rohschließkanals, including Rohschließprofil, safer, also profile element recordings 140 provided the breakthroughs 145 in the closing channel 9 produce. In the profile shots 140 then become interchangeable profile elements 130 inserted, which protrude at least partially and at least partially into the Rohschließkanal. The combination becomes the closing channel 9 realized with the closing profile.

11 schematically shows the detail view X of the 7 , In 11 is a completed and ready to use lock channel 9 shown with variable and fixed closing profile. Next to the closing channel 9 or in the closing channel 9 the lock core points outward 8th a kind of stepped bore or a stepped bore section 142 on. One as a rotationally symmetrical profile roller 137 with radially different sized portions is with one end in the stepped bore portion 142 added. For this purpose, the pin has a shoulder 132 on, with which this rests on a shoulder of the stepped bore. The end of the pin and the end of the stepped bore are thus spaced from each other and form a narrow gap. The pen is peripherally supported in the stepped bore. In this way, a rotational movement of the pin is ensured in the stepped bore. The pin has wave heel-like sections which have different dimensions, with rotationally symmetrical design different diameters. Two different sections 136 are exemplary with 136a and 136b characterized. When inserting a key 12 with corresponding complementary profiling, the projecting sections 136 the profile elements 130 along the complementary profiling of the key 12 , By enabling rotation of the pin-like profile elements 130 Friction is reduced, making it easier to insert the key 12 is guaranteed with more complex profiling.

12 schematically shows the detail view Y of the 8th , supplemented by a section of an associated key 12 , The key 12 forms at least partially a to a closing profile of the closing channel 9 or a closing profile of the profile elements 130 at least partially complementary key profile. As an example, a closing profile-key profile combination is shown here. The profiles or profile sections 13 and 14 or around the letters a to d supplemented sections are each pairwise complementary, so that in the following only one profile is described and this is then transferred in a complementary manner to the other, complementary profile. Left in 12 is a cutout of a key 12 by way of example four different profile recesses 13 respectively. 13a to 13d shown. Accordingly, right is in 12 a section of a locking core 8th with closing channel 9 shown in the complementary a portion of a closing profile 14 with four complementary, protruding closing profiles, closing profile sections or profile sections 14 respectively. 14a to 14d is provided. The profiles 13 . 14 with the index a are designed as rounding, rounding concave or convex. The curve of the contour in the illustrated cross section is approximately semicircular. The profiles 13 . 14 with the index b are designed as a mathematical function. For the contour of the profiling cross-section, this mathematical function comprises curves which, for example, may be logarithmic, exponential, sinusoidal, cosine-shaped, hyperbolic, polynomial, trigonometric, potential, linear, rational. In the present case, an approximately semi-parabolic mathematical curve is provided. The profiles 13 . 14 with the index c are intended as a V-shaped profiling. The flanks of the profiles 13c . 14c taper to a bottom of Profilierungsausnehmung or up to an end wall of a profiling projection and run together preferably there. The profiles 13 . 14 with the index d have a kind of rectangular course. The flanks are approximately parallel here. Manufacturing technology, the transitions are preferably rounded or chamfered, which is not shown here.

The 13 to 24 show another embodiment in the same views as in FIGS 1 to 12 , The embodiment according to the 1 to 12 concerns conventional key-lock cylinder combinations. Here is an orientation of the closing channel 9 or the key shaft 12 ' edgewise when inserted, that is in extension to the radially of the cylinder wall 4 protruding housing section 5 intended. In contrast to a conventional key is in a reversible key, as is the embodiment of the 13 to 24 shows, the key profile on both sides of the shaft formed the same, so that the key turned 180 ° about its longitudinal axis in the closing channel 9 can be used. The reversible key thus has the same functional features with respect to the closing profile even when the orientation is rotated about its longitudinal axis - the use is thus independent of the side. Accordingly, in 13 key 12 and the closing channel 9 transversely (horizontally) instead of vertically aligned. The closing nose 41 is shown in its initial position. 14 corresponds to 13 without a key 12 , A major difference with respect to the lock core 8 will become apparent from the other figures. Instead of using traditional keys 12 according to 1 to 12 Profile element receptacles 140 on both sides of the median plane ME provide the closing channel 9, the lock core 8th only on one side of the median plane ME Profile element receptacles 140 in which then the respective profile elements 130 are provided. Of course, in other embodiments also on both sides of the median plane ME Profile element receptacles 140 be provided. Only due to the key symmetry of reversible keys the profile element recordings 140 one side of the median plane ME not with profiling profile elements 130 executed, but possibly with dummy pins, which do not complement the contour of the Rohschließkanals profiling, that is, for example, no additional projections through the openings 145 exhibit. The orientation of the profile element recordings 140 is correspondingly horizontal (horizontal). Also the insertion of the profile elements 130 takes place in an approximately 90 ° compared to conventional key-lock core combinations (see 16 ).

Not all profile element recordings 140 need with profile elements 130 be occupied. In 16 For example, only two variable profile elements 130 intended.

13 shows schematically in a perspective view an embodiment of a closing device 100 comprising a lock cylinder 1 and a corresponding reversible key 12 , In the 13 is the lock cylinder 1 designed as a profile double cylinder. This each includes a cylinder housing 2 , which consists of a cylinder opening exhibiting a circular cross-section cylinder wall 4 and one of this radially outwardly uniform material web portion 5 composed. In the cylinder opening is ever a locking core 8th arranged, for example by means of a clamping ring 43 axially fixed, similar to in 1 and 2 , The cylinder wall 4 forms with its inner wall a core hole into which the cylinder core or lock core 8th is used. In the lock core 8th is a radial cut keyway or closing channel 9 (please refer 14 ; incorporated here only schematically), the one side of the lock core 8th is open and with a longitudinal median plane of the web section 5 flees. In a known manner takes the lock core 8th at least two-part locking elements, tumbler pins and / or housing pins 10 (see ua 20 ), which are in 13 are not explicitly shown and the key shaft side depressions of the reversible key 12 be classified. The core-side ends in the direction of the closing channel 9 spring-loaded tumbler pins 10 project stop limited in the closing channel 9 into it. Such tumbler pins 10 However, they are known so that they will not be discussed further. Around a rotation axis of the cylinder wall 4 , is in a recess 42 a closing unit 40 with a closing nose 41 added. This is when turning a matching to the closing profile key 12 that is with a key 12 with corresponding key profile and to the tumbler pins 10 matching keyshaft side recesses rotated about the axis of rotation, thus realizing a closing function of the lock cylinder 1 which is well known.

14 shows schematically in perspective view the embodiment of the lock cylinder 1 to 13 without corresponding reversible key 12 , Accordingly, the closing profile of the closing channel 9 clearly visible. This has recesses, recesses and projections, on the one hand along a main extension of the closing channel 9 run and that of a median plane ME are formed on both sides of the plane. Over the course along the main extension of the closing channel 9 the closing profile can vary.

15 shows schematically in a perspective view an embodiment of a lock cylinder 1 in which an upper cylinder wall section is removed. In this way, the closing channel 9 visible along its entire main extension. How out 15 and also out 3 can be seen, the lock core 8th next to the profiled closing channel 9 Profile element receptacles 140 on, in which profile elements 130 , here in the form of profile rolls 137 , are introduced or are introduced. The profile element recordings 140 are here as receiving holes 141 formed and cut at least partially the closing channel 9 so that the mounting holes 141 and the closing channel 9 partially overlap and so a common profile channel is realized. In the mounting holes 141 are (here only partially) the profile elements 130 plugged in. These are designed so that these with a part in the closing channel 9 protrude and form part of the closing profile.

16 shows schematically in a partial exploded view of the embodiment according to 13 , Here is clearly the formation of the profile elements 130 and the profile element recordings 140 to recognize. The profile element recordings 140 are unilaterally the median plane ME of the closing channel 9 intended. In this case, a part of the mounting holes overlaps 141 with a part of the closing channel 9 , so each one breakthrough 145 between receiving bores 141 and closing channel 9 is trained. In the mounting holes 141 whose main extension is approximately parallel to the plane of the median plane ME of the closing channel 9 runs are the profile elements 130 plugged in or inserted. The profile elements 130 are here as rotationally symmetrical profile elements 130 , more precisely as profile rolls 137 formed with rotationally symmetrical cross-section. In this case, the cross section varies along an axis of the profile rollers 137 so that the profile elements 130 only intermittently or in sections into the closing channel 9 through the respective openings 145 protrude. The profile rollers 137 themselves are differently formed. Due to the different design of the profile rollers 137 Different closing profiles can be realized.

17 schematically shows a side view of the embodiment according to 13 with illustrated different view or cutting planes. A cutting plane AA passes through a remotest to a front or key insertion side of the lock core 8th approximately in the middle by the rearmost profile element holder 140 , A cutting plane A1-A1 runs approximately in the middle through the second frontmost profile element holder 140 , A cutting plane A2-A2 runs approximately centrally through the foremost profile element receptacle 140 , A view plane A3-A3 runs along a front side F of the lock core 8th ,

18 shows schematically the section AA of the embodiment according to 17 , The cylinder wall 4 of the cylinder housing 2 surrounds the lock core 8th full. In the lock core 8th are the closing channel 9 as well as on both sides of each a profiled element recording 140 in the form of a receiving bore 141 intended. This overlaps or overlaps part of the mounting hole 141 with the closing channel 9 so breakthroughs 145 are realized. The closing channel 9 itself has a lateral closing profile, which by projections or recesses in the direction of the two-sided profile element recordings 140 is formed. By inserting corresponding profile elements 130 in the profile element recordings 140 , as in 7 shown, can be realized as a complex, variable closing profile.

19 shows schematically the section A1-A1 of the embodiment according to 17 , In the profile element recordings 140 are different profile elements 130 added. The closing profile of the closing channel 9 varies over its main extension direction. Due to the different profile elements 130 In addition, an exchangeable closing profile section is formed. It is easy to see that the profile elements 130 partly in the closing channel 9 through appropriate breakthroughs 145 protrude. By appropriately filling or releasing the breakthroughs 145 through the interchangeable profile elements 130 is next to a fixed or fixed profile section of the closing channel 9 implemented a variable profile section. The profile elements 130 are with an end portion in a corresponding portion of the profile element receptacle 140 stored as in detail view X ( 22 ) is described.

In this way, a variable closing profile is realized. In detail view Y a part of the closing profile is shown enlarged.

21 shows schematically the view A3-A3 of the embodiment according to 17 , In 21 is the front F of the lock core 8th shown with a view in the main extension direction of the closing channel 9 , In this view is clearly the closing profile of the closing channel 9 to recognize. The closing profile consists of a fixed, unchangeable part 9a and a variable, variable part 9b , The fixed part is defined by the contour of the closing channel 9 self determined For this purpose, the closing channel 9 corresponding projections and recesses. These are during training or introduction of the closing channel 9 in the lock core 8th established. The variable part 9b is formed by the projections and recesses of the profile elements 130 formed, which from the profile element recordings 140 through the breakthroughs 145 in the closing channel 9 protrude or not protrude. Because the profile elements 130 interchangeable, can be the variable part 9b by exchanging the profile elements 130 change.

22 schematically shows a cross section through an embodiment of a lock core 8th before training profile element shots 140 , In the lock core 8 is the profile channel 9 brought in. This has the main extension direction in the direction of view. The center plane is marked ME This extends radially to the lock core 8th and in the direction of view, ie in the main direction of extension. The closing channel 9 is groove-like in the lock core 8th introduced, so that a breakthrough on a circumference of the lock core 8th this results and the closing channel 9 forms a kind of groove or slot. The closing channel 9 according to 22 is still designed as Rohschließkanal, ie without providing profile element recordings 140 and profile elements 130 , The raw closing channel thus forms the fixed or tool-free invariable part of the closing channel 9 from, who may already have a machined introduced profile. The raw closing channel is preferably machined in the lock core 8th educated. The closing profile of the raw closing channel here has projections, ribs, recesses, grooves and the like. These are in 22 mirror asymmetric to the median plane ME educated. The present (fixed) closing profile of the raw closing channel has on both sides of the median plane ME two recesses, which are separated by a projection. Here are the projections 9d each arranged so that a total of one closing channel 9 with a predetermined minimum width, in which a key remains 12 is insertable.

In order to make the closing profile of the Rohschließkanals, including Rohschließprofil, safer, also profile element recordings 140 provided the breakthroughs 145 in the closing channel 9 produce. In the profile shots 140 then become interchangeable profile elements 130 inserted, which protrude at least partially and at least partially into the Rohschließkanal. The combination becomes the closing channel 9 realized with the closing profile.

23 schematically shows the detail view X and 24 schematically shows the detail view Y. In 23 and 24 is a completed and ready to use lock channel 9 shown with variable and fixed closing profile. The closing channel 9 has at its non-open end a kind of blind bore or a blind bore portion 142 on. A designed as a rotationally symmetric pin with radially different sized sections profile element 130 - the profile role 137 is with one end in the stepped bore section 142 added. For this purpose, the pin or better the role has a shoulder 132 on, with which this rests on a shoulder of the stepped bore. The end of the pen or roll 137 and the end of the stepped bore are thus spaced from each other and form a narrow space. Completely the profile roller is mounted in the stepped bore. In this way, a rotational movement of the profile roller 137 ensured in the stepped bore. The roller has wave-heel-like sections which have different dimensions, with rotationally symmetrical design different diameters. Two different sections are exemplary with 136a and 136b characterized.

25 shows schematically in a perspective view an embodiment of a lock core 8th with a key 12 in not plugged in condition. The key 12 is as related to 1 or 13 described trained. The lock core 8th has a closing channel or key channel 9 on, which is parallel to a median plane ME extends approximately radially and the lock core 8th penetrates in one direction, so that a slot-shaped closing channel 9 results. The closing channel 9 , more precisely, the raw closing channel, is thus approximately cuboid, optionally formed with a solid profile, which also embodiments may result in the radial and / or axial direction tapering or varying contour. The lock core 8th has a front area 110 and a base part 120 on. Diagonally to the slot-shaped closing channel 9 , here approximately perpendicular to it, are bores 121 for tumbler elements 10 educated. These are preferably on a flattened area 122 in the radial direction in the base part 120 brought in. The base part 120 has an approximately slotted-cylindrical shape. A diameter or a radial extension of the base part 120 is smaller than a corresponding diameter or a corresponding radial extent of the likewise approximately slotted-cylindrical front region 110 , The larger front area 110 coaxial with the base part 120 is arranged, thus projects circumferentially in the radial direction over the base part 120 and serves, for example, as a stop for the cylinder (-kern-) housing not shown here 2 or the cylinder wall 4 (not shown here). In the radial direction of extension of the closing channel 9 are one-sided in one to the closing channel 9 adjacent Schließkanalwandung formed as a radially extending recesses profile element recordings 140 provided, on one side the base part 120 penetrate. The radial recesses are in a direction to the closing channel 9 opened and for receiving profiling profile elements 130 educated. The radial recesses are accordingly as profile element recording 140 designated. The profile element recordings 140 are spaced from each other and thus each of a web training 133 in the corresponding side wall of the closing channel 9 separated. The respective bridge training 133 or web wall and thus the distance between the profile element recordings 140 is preferably identical, so that the profile element recordings 140 are arranged equidistant from each other. The profile element recordings 140 here have an approximately semi-cylindrical, in particular groove-shaped and are as holes partially in the lock core 8th and partly in the closing channel 9 brought in. In this case, the respective bore or the profile element receptacle 140 a stepped bore section 142 and a groove portion 144 on, so in the profile element recording 140 recorded profile elements 130 at least partially in the stepped bore cuttings 142 and partially in the groove portion 144 are received, whereby a storage of the recorded profile elements 130 is realized. The profile elements 130 are preferably cylindrical as a profile roll 137 educated. This show the profile elements 130 cylindrical sections 136 with different diameters and / or different widths. At least one cylindrical section is designed so that this on the profile element receptacle 140 in the closing channel 9 partially protruding and so the closing channel 9 through this supernatant gives a profile. Preferably, a plurality of cylindrical portions protrude 136 partly via the profile element holder 140 in the direction of the closing channel 9 out, so that a more complex profile for the (raw) closing channel 9 is formed. The profile elements 130 are preferably rotatable in the profile element receptacle 140 stored so that they are in contact with a corresponding, profiled key 12 with the insertion movement of the key 12 can rotate. Preferably, the profile elements 130 a friction-reducing layer or the like, so that these even more smoothly rotatable in the profile element recording 140 are stored. The profile elements 130 can be in the profile element recording 140 interchangeable and / or tool-free use. In this way can be in a lock or cylinder core 8th different profiles for a closing or key channel 9 by using different profile elements 140 realize. The lock core 8th is preferably in one piece with the exception of the profile elements 140 and the locking pins 10 educated. Thus, the base section 120 with the front area 110 formed in one piece.

The in the profile element recording 140 used profile elements 130 partially protrude over the profile element recording 140 in the closing or key channel 9 and thus form a variable or variable profile for the closing channel 9 out. The holes for the profile element holder 140 are more than 50% in the lock core 8th or its base part 120 trained and a correspondingly smaller part is in the closing channel 9 protruding, so that a groove-shaped portion or groove portion 144 results (except the stepped bore section 142 or blind hole section). The length of the profile elements 130 in the main extension direction (axial direction) substantially corresponds to the length of the profile element receptacle 140 in its main extension direction (axial direction), so that the profile elements 130 axially non-displaceable in the profile element receptacle 140 are, as soon as the lock core 8th is surrounded by the formed as a cylinder wall housing portion. The width and / or the diameter of the individual cylindrical sections 136 is / are at least partially different. The individual cylindrical sections 136 are preferably formed integrally connected to each other. But it can also provide separate sections, so that a multi-part profile element is realized The profile elements 136 protrude with a lateral or lateral portion in the closing channel 9 , in contrast to the locking pins 10 , which with an end portion in the closing channel 9 protrude, across the profile elements 130 , at least if no key 12 in the key channel 9 is introduced. The lock cylinder 1 with the lock core 8th and the key 12 are part of the locking device 100 , here to clarify the principle of action of the lock core 8th only the lock core 8th and the key 12 shows.

26 shows schematically in another perspective view of the lock core 8th the embodiment according to 25 in isolation. The profile element recordings 140 have a stepped bore section 142 (not explicitly shown here) and a groove-shaped groove portion 144 on. In the stepped bore section 142 is the profile element 130 Surrounded completely, so that in the area a storage is realized. From the opposite the stepped bore section 142 axially longer, groove-shaped groove portion 144 , the different cylindrical sections protrude 136 at least partially laterally into the closing channel 9 and thus form a lateral boundary, thus a profile, for one in the closing channel 9 to key. Due to the cylindrical design of the profile elements 130 is a resistance between key and profile elements 130 reduced, especially the profile elements 130 rotatable in the profile element recordings 140 are stored. Due to the axial fixation of the profile elements 130 the profile is fixed axially. By replacing the profile elements 130 and / or the cylindrical sections 136 can spanless variously through one in the closing channel 9 insertable key 12 unchangeable profiles for the closing channel 9 realize. In contrast to the locking pins 10 is that by the profile elements 130 formed profile through an inserted key 12 not changed. Some of the sections 136 do not protrude beyond the edge of the profile element holder 140 out. In this way, a complex profile for the closing channel 9 can be realized.

27 shows schematically in a perspective view an embodiment of the key shank 12 ' arranged differently and as a profile role 137 and profile pin 138 trained profile elements 130 , Shown is a profiled key 12 and with the key 12 engaged profile elements 130 , Further details have been omitted for clarity. As in 27 are four of the five variable profile elements 130 as profile pins 138 and a profile element 130 as a profile role 137 educated. The profile role 137 protrudes with its lateral contour in the corresponding contour of the key 12 , In this case, the profile role 137 different sections with different diameters on. On a narrow side of the key 12 are recesses for locking pins 10 intended. The orientation of the profile roller 137 is parallel to the orientation of - not here illustrated - Zuhaltestifte 10 , Transverse to the orientation of the profile roller 137 is the orientation of the profile pins 138 , The profile pins 138 are aligned so that one end of the profile pins 138 to cooperate or intervene with the profile of the key 12 is trained. These are three of the four profile pins 138 substantially perpendicular to a broad side of the key 12 aligned. A fourth profile pin 138b is transverse to the other profile pins 138 aligned. Due to the oblique orientation of the profile pin 138b for forming a closing profile with undercut S intended. This will be in 28 more clear.

28 schematically shows the embodiment according to 27 in a frontal view overlooking the key tip. The profile pin 138b is oblique to the other profile pins 138 aligned. In this way, a closing profile with an undercut S realized.

Thus, the embodiment after 27 and 28 a closing profile with fixed and variable profile elements 130 ready, with the variable profile elements 130 partly as a profile role 137 and partly as profile pins 138 are formed. With this embodiment, a flexible coding is ensured, with an influence on the Zuhaltestifte 10 is reduced.

It is understood that the abovementioned features of the invention can be used not only in the respectively specified combination but also in other combinations or in isolation, without departing from the scope of the invention.
