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 Profiling profile element fixed, that is integrally and / or integrally formed with the lock core and at least one variable profile element is formed separately and / or detachable to the closing channel, a base portion of the lock core and / or the lock core, so that the closing profile by replacing 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 is designed as a about a profile element axis rotationally symmetrical profile body.

An embodiment provides that a lock core is provided for a lock cylinder, comprising a closing profile having a closing channel, wherein the closing channel is bounded laterally by two side walls and a bottom wall of the lock core, wherein the locking channel is at least partially delimiting closing profile defined by profile-giving profile elements in that the side wall is profiled by profiling elements, wherein at least one profiling profiled element is fixed, ie integral, with the lock core and at least one variable profile element is formed separately and / or releasably to the closing channel or the lock core, so that the closing profile by a Replacement of the at least one separate profiling variable profile element is changeable, wherein the lock core is integrally formed, wherein the at least one variable profile element as a rotatio about a profile element axis symmetrical profile body is formed.

In one embodiment, it is provided that a closing core is provided, comprising or comprising a closing channel which is bounded laterally by a respective side wall and the bottom side by a bottom wall, wherein the closing channel is open on a fourth side, opposite to the bottom wall, wherein the closing channel is profiled by profile elements, wherein the profile elements are mounted in the direction of a profiling or against the direction translationally immovable, so that the profiling is not changed by the profile elements when inserting a key in the closing channel, further Zuhaltestifte are provided, which are resiliently mounted, so that they adapt to the key when a key is inserted into the closing channel, at least one profiling profiled element being fixed, that is to say integrally and / or integrally formed with the closing core and at least one variable profiled element at least rotatable, separately and / or releasably formed to the closing channel or the lock core, so that the closing profile is changeable by an exchange of the at least one separate profiling variable profile element. The variable or variable profile element can be replaced or replaced in the removed state of the lock core. In the installed state, that is to say in the ready state, the variable or variable profile element is fixedly arranged counter to a direction in which it projects into the closing channel in a profiling manner. Preferably, the variable or variable Profile element in the installed state or in the operating state stationary and / or rotatably arranged. The profile element may be formed as a profile roll or profile pin. The profile roll forms a profile with its flanks. The profile pin forms a profile with its tip. In the case of a plurality of variable or variable profile elements, these may be identical or different. For example, at least one variable profile element is designed as a profile roller and formed at least one variable profile element as a profile pin. In another embodiment, all variable profile elements are designed either as a profile roller or as a profile pin.

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 opposite, the closing channel is open. While preferably 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 and protrude into this yielding. Under 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. Tacking pins according to the invention are not to be understood as profile elements. In contrast to the locking pins, the profile elements are not translationally yielding. Rather, the profile pins form an unchangeable when inserting a key profile, that is, the profile elements are translationally not resiliently mounted. At most a rotational movement, that is called a rotational movement about the profile element axis is possible. Thus, the profile elements are preferably non-spring mounted. The tumbler pins, however, are mounted translationally yielding. This is caused by a resilient mounting in the translational direction, that is in the direction in which the Zuhaltestifte protrude into the keyway or protrude into this. Thus, the tumbler pins are in or against the direction in which they protrude into the keyway / closing channel, resiliently or movably arranged. The profile elements are in the direction or against the direction in which they protrude into the key channel / closing channel, unyielding or not movable.

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 formed as machined or integrally formed with the lock core projections and recesses are firmly formed with a part of the lock core, for example, by broaching, milling or other machining manufacturing process, or by exclusively interchangeable , Separate variable profile elements, in the inventive solution at least one profilgebendes variable profile element 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 only with separate variable profile elements realized closing profiles are to be arranged at least in conventional keys in the field of Zuhaltestifte. Thus, in the solution according to the invention, there is no collision of locking pins and profile elements.

The side walls of the closing channel are preferably arranged parallel to one another. A foot or foot region of at least one profile element is non-tapered in one embodiment.

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 forms an undercut in the closing channel. 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, the profile element receptacle having 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 or 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, preferably for receiving profile element rollers or profile roller elements. In other embodiments, the profile element receptacle is designed as a bore, in particular as a stepped bore, preferably for receiving profile pins or as a blind hole, preferably for receiving profile rollers. The profile element receiving has in embodiment as a groove groove-shaped portion or part and a stepped bore portion or stepped bore portion. 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 channel Closing channel in the radial direction of the lock 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 another embodiment with profiled pins, a profiled element receptacle is essentially formed as a bore in the corresponding side wall of the closing core which delimits the closing channel laterally. The profile element receptacle in this case has a cylindrical portion or part. Preferably, the profile element receptacle is formed by means of drilling or drilling. The hole penetrates radially through the lock core and opens into the closing channel. The profile element receptacle is thus substantially cylindrical. Other embodiments such as rectangular shapes or oval, triangular, quadrangular, polygonal, conical 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 profiled element at least in sections has 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. With one end, that is preferably formed as a tip, the variable profile element protrudes through the opening in the closing channel and thus forms a variable part of the closing profile. A closing profile is thus at least partially formed by a tip or an end of the variable profile element. In other embodiments, a further profile element receptacle may be formed as a groove and / or bore, wherein the further profile element receiving has an opening or a plurality of openings to the closing channel. In this way, a closing profile can be formed by an edge 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 several 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 receiving and thus also the recorded variable profile element or tumbler pin transversely and / or non-locking. 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 orientation of the tumbler pins is aligned parallel or equal 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 different. In particular, in one embodiment, the orientations are oriented transversely or at an angle to one another, in particular perpendicular to one another. 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.

In a further embodiment, the length of the variable or 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 region 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 or direction in the lock core. In this case, the alignment of the profile element receptacles in the same direction as the orientation of the Zuhaltestiftaufnahmen or be aligned transversely thereto. 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 parallel to the orientation of the tumbler pins or Zuhaltestiftaufnahmen. In conventional keys, the orientation is preferably perpendicular.

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 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 fixed profile element preferably has a 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.

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.

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.

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.

In a further embodiment it is provided that at least one profile-giving variable profile element is formed as a profiled profiled element, which has at least two different radial or lateral or lateral dimensions over an extension direction or in the axial or longitudinal direction. The respective profile element can have any desired contour, which then defines the closing profile. Thus, in a profile roller, the outer contour of the profile element forms a kind of control cam.

The profile element is preferably formed as an elongated body. This has a main extension direction, which is also referred to as the axial direction of the profile element. Laterally, the dimensions of the body vary, so that any profile can be realized. The variation can be continuous or discontinuous, thus jumpy, be formed.

Accordingly, in one embodiment it is provided that at least one variable or variable profile element is designed as a rotation axis with at least two radial projections spaced apart in the extension direction, in particular rotationally symmetrical cylindrical radial projections. 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 Fig. 1 to 53 show in different views and degrees of detail a closing unit or closing device 100 or its components.

Fig. 1 schematically shows in a perspective view of an embodiment of a locking device 100 with a lock cylinder 1 and a corresponding key 12 or key unit. In the Fig. 1 the lock cylinder 1 is designed as a profile double cylinder. This comprises a cylinder housing 2, which is composed of a respective cylinder opening exhibiting, circular in cross-section cylinder wall 4 and a radially outgoing material of this web portion 5 composed. In each cylinder opening a cylinder core or lock core 8 is arranged, which is fixed axially, for example by means of a clamping ring 43 (see FIG. 13 ). The cylinder wall 4 forms with its inner wall a core bore into which the lock core 8 is inserted. In the lock core 8 is a radially cut keyway 9 (see Fig. 2 ; here only schematically indicated) incorporated, which is open to one side of the lock core 8 and aligned with a longitudinal center plane of the web portion 5. In a known manner, the lock core 8 takes at least two-part tumblers, tumbler pins, tumbler pins and / or housing pins 10 (see, inter alia Fig. 20 ), which are in Fig. 1 are not explicitly shown and are classified by key shaft side wells of the key 12. The core-side ends of the sprung in the direction of the key channel 9 tumbler pins 10 protrude stop limited in the keyway 9 into it. Such tumbler pins 10 are known, however, so will not be discussed in more detail. To a rotation axis of the cylinder wall 4, in a recess 42, a closing unit 40 with a locking lug 41 (see FIGS. 13 and 14 ). This is rotated when turning to the closing profile matching key 12, that is, with a key 12 with corresponding key profile and the tumbler pins 10 matching key shank side recesses around the axis of rotation, thus realizing a closing function of the lock cylinder 1, which is well known. The key 12 has, inter alia, a key shank 12 ', on which the key profile and the permutation holes are formed.

Fig. 2 schematically shows the embodiment of the lock cylinder 1 in perspective view Fig. 1 without a corresponding key 12. Accordingly, the closing profile of the closing channel 9 can be seen more clearly. This has recesses, depressions and projections which extend on the one hand along a main extension of the closing channel 9 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.

Fig. 3 shows schematically in a perspective view of an embodiment of a lock cylinder 1, in which an upper cylinder wall portion is removed. In this way, the closing channel 9 is visible along its entire main extension. How out Fig. 3 can be seen, the lock core 8 in addition to the profiled locking channel 9 profile element receptacles 140, in which separately formed, replaceable profile elements 130 can be introduced or are introduced. The profile element receptacles 140 are here designed as receiving bores 141 and at least partially intersect the closing channel 9, so that the receiving bores 141 and the closing channel 9 partially overlap and so a common profile channel or a common closing profile is realized. In the receiving holes 141 (here only partially), the profile elements 130 are inserted. These are designed so that they protrude with a part in the closing channel 9 and thus represent or form part of the closing profile.

Fig. 4 shows schematically in a partial exploded view of the embodiment according to Fig. 3 , Here is clearly the formation of the profile elements 130 and the profile element receptacles 140 can be seen. The profile element receptacles 140 are provided on both sides of the median plane of the closing channel 9. In this case, a part of the mounting holes 141 overlaps with a part of the closing channel 9, so that in each case an opening 145 between receiving holes 141 and closing channel 9 is formed. In the receiving holes 141, the main extension extends approximately parallel to the plane spanned plane of the center plane ME of the closing channel 9, the profile elements 130 can be inserted or inserted. The profile elements 130 are here designed as rotationally symmetrical profile elements 130, more precisely as profile rollers 137 with a 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 protrude only intermittently or in sections into the closing channel 9 through the respective apertures 145. 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.

Fig. 5 schematically shows a side view of the embodiment according to Fig. 3 with illustrated different view or cutting planes. A sectional plane AA extends through a remotest to a front or Schlüsseleinsteckseite the lock core 8 approximately centrally through the rearmost element element receptacle 140. A cutting plane A1-A1 extends approximately centrally through the zweitvorderste profile element receptacle 140. A cutting plane A2-A2 extends approximately centrally through the foremost Profile element receptacle 140. A view plane A3-A3 runs along a front side F of the lock core 8.

Fig. 6 schematically shows the section AA of the embodiment according to Fig. 5 , The cylinder wall 4 of the cylinder housing 2 surrounds the lock core 8 in full. In the lock core 8, the closing channel 9 and on both sides thereof each a profiled element receptacle 140 in the form of a receiving bore 141 are provided. In this case, a part of the receiving bore 141 overlaps or overlaps with the closing channel 9, so that apertures 145 are realized. The closing channel 9 itself has a lateral closing profile, which is formed by projections or recesses in the direction of the two-sided profile element receptacles 140. By inserting corresponding profile elements 130 in the profiled element receptacles 140, as in Fig. 7 shown, can be realized as a complex, variable closing profile.

Fig. 7 schematically shows the section A1-A1 of the embodiment according to Fig. 5 , In the profile element receptacles 140 different profile elements 130 are added in the form of profile rollers 137. The closing profile of the closing channel 9 varies over its main extension direction. In addition, an exchangeable, variable closing profile section is formed by the different profile elements 130. It can be clearly seen that the profile elements 130 project laterally partially into the closing channel 9 through corresponding apertures 145. By appropriately filling or releasing the openings 145, a variable profile section is realized in addition to a fixed or fixed profile section of the closing channel 9. The profile elements 130 are mounted with one end section in a corresponding section of the profiled element receptacle 140, as shown in detail view X (FIG. Fig. 11 ) is described.

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

Fig. 9 schematically shows the view A3-A3 of the embodiment according to Fig. 5 , In Fig. 9 is the front side F of the lock core 8 shown with a view into the Main extension direction of the closing channel 9. In this view, the closing profile of the closing channel 9 can be clearly seen. The closing profile 9 consists of a fixed, unchangeable part 9a and a variable, variable part 9b. The fixed part 9a is determined by the contour of the closing channel 9 itself. For this purpose, the closing channel 9 corresponding projections and recesses. These are defined in training or introduction of the closing channel 9 in the lock core 8. The variable part 9b is formed by the projections and recesses of the profile elements 130 - here the profile rollers 137 - which protrude laterally from the profile element receptacles 140 through the apertures 145 in the closing channel 9 or not protrude. Since the profile elements 130 are interchangeable, the variable part 9 b can be changed by exchanging the profile elements 130.

Fig. 10 schematically shows a cross section through an embodiment of a lock core 8 before the formation of profile element receptacles 140. In the lock core 8 of the profile channel 9 is introduced. This has the main extension direction in the direction of view. Plotted is the median plane ME. This extends radially to the lock core 8 and in the viewing direction, ie in the main extension direction. The closing channel 9 is groove-like introduced into the lock core 8, so that an opening 8a results in a circumference of the lock core 8 and the closing channel 9 forms a kind of groove or slot. The closing channel 9 according to Fig. 10 is still designed as Rohschließkanal, ie without provision of profile element receptacles 140 and profile elements 130. The Rohschließkanal thus forms the fixed or tool-less invariable part of the closing channel 9, which may already have a machined introduced profile. The raw closing channel is preferably formed by machining in the lock core 8. The closing profile of the raw closing channel here has projections, ribs, recesses, grooves and the like. These are in Fig. 10 formed mirror-symmetrical to the center plane ME. The present (fixed) closing profile of the Rohschließkanals has on both sides of the median plane ME two recesses, which are separated by a respective projection. In this case, the projections are each arranged so that a total of a closing channel 9 remains with a predetermined minimum width, in which a key 12 is inserted. The minimum width is required to prevent too thin key strengths and thus breakage of the key 12. 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 receptacles 140 are provided which produce openings 145 in the closing channel 9. In the profile receptacles 140 replaceable profile elements 130 are then inserted, which protrude at least partially and at least partially into the Rohschließkanal. By combining the closing channel 9 is realized with the closing profile.

Fig. 11 schematically shows the detail view X of Fig. 7 , In Fig. 11 is a finished and ready to use closing channel 9 shown with variable and fixed closing profile. In addition to the closing channel 9 or opening into the closing channel 9, the lock core 8 has a kind of stepped bore or a stepped bore section 142. A rotationally symmetrical profile roller 137 with radially differently dimensioned sections is accommodated with one end in the stepped bore section 142. For this purpose, the pin has a shoulder 132, with which this rests against 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 exemplarily labeled 136a and 136b. Upon insertion of a key 12 with correspondingly complementary profiling, the projecting portions 136 of the profile elements 130 extend along the complementary profiling of the key 12. By allowing rotation of the pin-like profile elements 130, friction is reduced, allowing for easier insertion of the key 12 with more complex profiling is guaranteed.

Fig. 12 schematically shows the detail view Y of Fig. 8 , complemented by a section of an associated key 12. The key 12 forms at least partially to a closing profile of the closing channel 9 and 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 sections or profile sections 13 and 14 or the sections supplemented by the letters a to d are each pairwise complementary, so that in the following only one profile is described and this is then to be transmitted in a complementary manner to the other, complementary profile. Left in Fig. 12 is a section of a key 12 with exemplary four different profile recesses 13 and 13a to 13d shown. Accordingly, right is in Fig. 12 a section of a locking core 8 shown with closing channel 9, in which a complementary section of a closing profile 14 with four complementary, projecting closing profiles, closing profile sections or profile sections 14 and 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 is an approximately semi-parabolic provided mathematical curve. The profiles 13, 14 with the index c are provided approximately as a V-shaped profiling. The flanks of the profiles 13c, 14c taper to a bottom of the profiling recess or up to an end wall of a profiling projection and preferably converge 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 FIGS. 13 to 24 show another embodiment in the same views as in FIGS FIGS. 1 to 12 , The embodiment according to the FIGS. 1 to 12 concerns conventional key-lock cylinder combinations. Here is an orientation of the closing channel 9 and the key shank 12 'when inserting upright, that is provided in extension to the radially projecting from the cylinder wall 4 housing portion 5. In contrast to a conventional key is in a reversible key, as is the embodiment of the FIGS. 13 to 24 shows, the key profile on both sides of the shaft formed the same, so that the key can also be used by 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 Fig. 13 Key 12 and the closing channel 9 transversely (horizontally) instead of vertically aligned. The locking lug 41 is shown in its initial position. FIG. 14 corresponds to FIG. 13 without key 12. A major difference with respect to the lock core 8 will become apparent from the other figures. Instead of 12 as in conventional keys Fig. 1 to 12 Profile element receptacles 140 to provide on both sides of the median plane ME of the closing channel 9, the lock core 8 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, the center plane ME profiled element receptacles 140 may be provided on both sides. However, due to the key symmetry in reversible keys, the profiled element receptacles 140 on one side of the median plane ME are not designed with profiling profiled elements 130, but at best with dummy posts which do not complement the contour of the raw occlusion channel, ie, have no additional protrusions through the apertures 145 , The orientation of the profile element receptacles 140 is correspondingly transverse (horizontal). The insertion of the profile elements 130 is also carried out in an approximately 90 ° compared to conventional key-lock core combinations (see Fig. 16 ). Not all profile element receptacles 140 must be occupied by profile elements 130. In Fig. 16 For example, only two variable profile elements 130 are provided.

Fig. 13 schematically shows in a perspective view of an embodiment of a closing device 100 comprising a lock cylinder 1 and a corresponding reversible key 12. In the Fig. 13 the lock cylinder 1 is designed as a profile double cylinder. This comprises each a cylinder housing 2, which consists of a cylinder opening exhibiting, circular in cross-section cylinder wall 4 and a radially outgoing material of this web portion 5 composed. In the cylinder opening a lock core 8 is arranged each, which is axially fixed, for example by means of a clamping ring 43, similar to in Fig. 1 and 2 , The cylinder wall 4 forms with its inner wall a core bore into which the cylinder core or lock core 8 is inserted. In the lock core 8 is a radially cut keyway or closing channel 9 (see Fig. 14 ; here only schematically indicated) incorporated, which is open to one side of the lock core 8 and aligned with a longitudinal center plane of the web portion 5. In a known manner, the lock core 8 takes at least two-part locking elements, tumbler pins and / or housing pins 10 (see, inter alia Fig. 20 ), which are in Fig. 13 are not explicitly shown and are classified by key shaft side depressions of the reversible key 12. The core-side ends of the sprung in the direction of the closing channel 9 tumbler pins 10 protrude stop limited in the closing channel 9 inside. Such tumbler pins 10 are known, however, so will not be discussed in more detail. Around a rotation axis of the cylinder wall 4, a closing unit 40 with a closing nose 41 is received in a recess 42. This is rotated when turning to the closing profile matching key 12, that is, with a key 12 with corresponding key profile and the tumbler pins 10 matching key shank side recesses around the axis of rotation, thus realizing a closing function of the lock cylinder 1, which is well known.

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

Fig. 15 shows schematically in a perspective view of an embodiment of a lock cylinder 1, in which an upper cylinder wall portion is removed. In this way, the closing channel 9 is visible along its entire main extension. How out Fig. 15 and also out Fig. 3 can be seen, the lock core 8 in addition to the profiled locking channel 9 profile element receptacles 140, in which profile elements 130, here in the form of profile rollers 137, are introduced or introduced. The Profile element receptacles 140 are here designed as receiving bores 141 and at least partially intersect the closing channel 9, so that the receiving bores 141 and the closing channel 9 partially overlap and so a common profile channel is realized. In the receiving holes 141 (here only partially), the profile elements 130 are inserted. These are designed so that they protrude with a part in the closing channel 9 and thus represent or form part of the closing profile.

Fig. 16 shows schematically in a partial exploded view of the embodiment according to Fig. 13 , Here is clearly the formation of the profile elements 130 and the profile element receptacles 140 can be seen. The profile element receptacles 140 are provided on one side of the center plane ME of the closing channel 9. In this case, a part of the mounting holes 141 overlaps with a part of the closing channel 9, so that in each case an opening 145 between receiving holes 141 and closing channel 9 is formed. In the receiving holes 141, the main extension extends approximately parallel to the plane spanned plane of the center plane ME of the closing channel 9, the profile elements 130 can be inserted or inserted. The profile elements 130 are here designed as rotationally symmetrical profile elements 130, more precisely as profile rollers 137 with a 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 protrude only intermittently or in sections into the closing channel 9 through the respective apertures 145. The profile rollers 137 themselves are designed differently. Due to the different design of the profile rollers 137 different closing profiles can be realized.

Fig. 17 schematically shows a side view of the embodiment according to Fig. 13 with illustrated different view or cutting planes. A sectional plane AA extends through a remotest to a front or Schlüsseleinsteckseite the lock core 8 approximately centrally through the rearmost element element receptacle 140. A cutting plane A1-A1 extends approximately centrally through the zweitvorderste profile element receptacle 140. A cutting plane A2-A2 extends approximately centrally through the foremost Profile element receptacle 140. A view plane A3-A3 runs along a front side F of the lock core 8.

Fig. 18 schematically shows the section AA of the embodiment according to Fig. 17 , The cylinder wall 4 of the cylinder housing 2 surrounds the lock core 8 in full. In the lock core 8, the closing channel 9 and on both sides thereof each a profiled element receptacle 140 in the form of a receiving bore 141 are provided. In this case, a part of the receiving bore 141 overlaps or overlaps with the closing channel 9, so that apertures 145 are realized. The closing channel 9 itself has a lateral closing profile, which by projections or recesses in the direction of two-sided profile element receptacles 140 is formed. By inserting corresponding profile elements 130 in the profiled element receptacles 140, as in Fig. 7 shown, can be realized as a complex, variable closing profile.

Fig. 19 schematically shows the section A1-A1 of the embodiment according to Fig. 17 , In the profile element receptacles 140 different profile elements 130 are added. The closing profile of the closing channel 9 varies over its main extension direction. In addition, an exchangeable closing profile section is formed by the different profile elements 130. It can be clearly seen that the profile elements 130 partially protrude into the closing channel 9 through corresponding apertures 145. By appropriately filling or releasing the apertures 145 by the replaceable profile elements 130, a variable profile section is realized in addition to a fixed or fixed profile section of the closing channel 9. The profile elements 130 are mounted with one end section in a corresponding section of the profiled element receptacle 140, as shown in detail view X (FIG. Fig. 22 ) is described.

Fig. 20 schematically shows the section A2-A2 of the embodiment according to Fig. 17 , Again, it can be clearly seen that the closing profile along the main extension direction of the closing channel 9 varies. In this way, a variable closing profile is realized. In detail view Y, part of the closing profile is shown enlarged.

Fig. 21 schematically shows the view A3-A3 of the embodiment according to Fig. 17 , In Fig. 21 is the front side F of the lock core 8 shown with a view in the main extension direction of the closing channel 9. In this view, the closing profile of the closing channel 9 can be clearly seen. The closing profile consists of a fixed, unchangeable part 9a and a variable, variable part 9b. The fixed part is determined by the contour of the closing channel 9 itself. For this purpose, the closing channel 9 corresponding projections and recesses. These are defined in training or introduction of the closing channel 9 in the lock core 8. The variable part 9b is formed by the projections and recesses of the profile elements 130, which protrude from the profile element receptacles 140 through the openings 145 in the closing channel 9 or do not protrude. Since the profile elements 130 are interchangeable, the variable part 9 b can be changed by exchanging the profile elements 130.

Fig. 22 schematically shows a cross section through an embodiment of a lock core 8 before the formation of profile element receptacles 140. In the lock core 8 of the profile channel 9 is introduced. This has the main extension direction in the direction of view. Shown is the median plane ME This extends radially to the lock core 8 and in the viewing direction, ie in the main extension direction. The closing channel 9 is groove-like in introduced the lock core 8, so that an opening on a circumference of the lock core 8 results from it and the lock channel 9 forms a kind of groove or slot. The closing channel 9 according to Fig. 22 is still designed as Rohschließkanal, ie without provision of profile element receptacles 140 and profile elements 130. The Rohschließkanal thus forms the fixed or tool-less invariable part of the closing channel 9, which may already have a machined introduced profile. The raw closing channel is preferably formed by machining in the lock core 8. The closing profile of the raw closing channel here has projections, ribs, recesses, grooves and the like. These are in Fig. 22 formed mirror-symmetrical to the center plane ME. The present (fixed) closing profile of the Rohschließkanals has on both sides of the median plane ME two recesses, which are separated by a respective projection. The projections 9d are each arranged so that a total of a closing channel 9 remains with a predetermined minimum width, in which a key 12 is inserted. The minimum width is required to prevent too thin key strengths and thus breakage of the key 12. 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 receptacles 140 are provided which produce openings 145 in the closing channel 9. In the profile receptacles 140 replaceable profile elements 130 are then inserted, which protrude at least partially and at least partially into the Rohschließkanal. By combining the closing channel 9 is realized with the closing profile.

Fig. 23 schematically shows the detail view X and Fig. 24 schematically shows the detail view Y. In FIGS. 23 and 24 is a finished and ready to use closing channel 9 shown with variable and fixed closing profile. The closing channel 9 has a kind of blind bore or a blind bore section 142 at its non-open end. A profile element 130 embodied as a rotationally symmetrical pin with radially differently dimensioned sections - the profile roller 137 - is accommodated with one end in the stepped bore section 142. For this purpose, the pin or better the role of a shoulder 132, with which this rests against a shoulder of the stepped bore. The end of the pin or roller 137 and the end of the stepped bore are thus spaced from each other and form a narrow gap. Completely the profile roller is mounted in the stepped bore. In this way, a rotational movement of the profile roller 137 is 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 exemplarily labeled 136a and 136b. When inserting a key 12 with correspondingly complementary profiling, the projecting portions 136 of the profile elements 130 extend along the complementary profiling of the key 12 Allowing rotation of the pin-like profile elements 130, a friction is reduced, so that an easier insertion of the key 12 is ensured at more complex profiling.

Fig. 24 schematically shows the detail view Y, supplemented by a section of an associated key 12. The key 12 forms at least partially from the closing profile at least partially complementary key profile. By way of example, a closing profile-key profile combination is shown here. The profiles or profile sections 13 and 14 or the sections supplemented by the letters a to d are each pairwise complementary, so that in the following only one profile is described, and then in a complementary manner to the other , complementary profile is to transfer. Down in Fig. 24 is a section of a key 12 with exemplary four different profile recesses or profile sections 13 and 13a to 13d analogous to Fig. 12 shown. Correspondingly, is above in Fig. 24 a section of a locking core 8 shown with closing channel 9, in which a complementary section of a closing profile 14 with four complementary, protruding profiles 14 and 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 formed 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 provided approximately as a V-shaped profiling. The flanks of the profiles 13c, 14c taper to a bottom of the profiling recess or up to an end wall of a profiling projection and preferably converge 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.

Fig. 25 schematically shows in a perspective view of an embodiment of a lock core 8 with a key 12 in the uninstalled state. The key 12 is as associated with, for example Fig. 1 or 13 described trained. The locking core 8 has a closing channel or keyway 9, which extends approximately radially parallel to a center plane ME and penetrates the locking core 8 in one direction, so that a slot-shaped closing channel 9 results. The closing channel 9, more precisely the Rohschließkanal, is thus approximately cuboid, possibly formed with a solid profile, which also embodiments may result in the radial and / or axial direction tapering or varying contour. The lock core 8 has a front region 110 and a base part 120. Diagonally to the slot-shaped closing channel 9, here about perpendicular thereto, bores 121 are formed for tumblers 10. These are preferably introduced into the base part 120 on a flattened region 122 in the radial direction. 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 also approximately slotted-cylindrical front portion 110. The larger front portion 110, which is arranged coaxially with the base part 120, thus projects circumferentially in the radial direction the base part 120 and thus serves, for example, as a stop for the not shown here cylinder (-kern-) housing 2 and the cylinder wall 4 (not shown here). In the radial extension direction of the closing channel 9 profiled element receptacles 140 designed as radially extending recesses 140 are provided on one side in a closing channel wall adjoining the closing channel 9 and penetrate the base part 120 on one side. The radial recesses are opened in a direction to the closing channel 9 and formed for receiving profiling profile elements 130. The radial recesses are referred to as profile element receptacle 140 accordingly. The profile element receptacles 140 are spaced apart from each other and thus separated by a respective web formation 133 in the corresponding side wall of the closing channel 9. The respective web formation 133 or web wall and thus the distance between the profile element receptacles 140 is preferably the same, so that the profile element receptacles 140 are arranged equidistant from each other. The profile element receptacles 140 here have an approximately semi-cylindrical, in particular groove-like shape and are introduced as holes partially in the lock core 8 and partially in the closing channel 9. The respective bore or the profiled element receptacle 140 has a stepped bore section 142 and a groove section 144, so that profiled elements 130 received in the profiled element receptacle 140 are accommodated at least partially in the stepped bore section 142 and partially in the groove section 144, thereby realizing a mounting of the received profile elements 130 is. The profile elements 130 are preferably formed cylindrically as a profile roller 137. The profile elements 130 have cylindrical sections 136 with different diameters and / or different widths. At least one cylindrical section is designed such that it protrudes partially over the profiled element receptacle 140 into the closing channel 9 and thus gives the closing channel 9 a profile through this projection. Preferably, a plurality of cylindrical portions 136 protrude partially over the profile element receptacle 140 in the direction of the closing channel 9, so that a more complex profile for the (raw) closing channel 9 is formed. The profile elements 130 are preferably rotatably mounted in the profile element receptacle 140 so that they can rotate in contact with a corresponding, profiled key 12 with the insertion movement of the key 12. Preferably, the profile elements 130 have a friction-reducing layer or the like, so that they are more easily rotatably mounted in the profile element receptacle 140. The profile elements 130 can be exchangeable and / or used without tools in the profile element receptacle 140. In this way, 8 different profiles for a closing or keyway 9 can be realized by using different profile elements 140 in a lock or cylinder core. The lock core 8 is preferably formed integrally with the exception of the profile elements 140 and the tumbler pins 10. Thus, the base portion 120 is formed integrally with the front portion 110.

The profiled elements 130 inserted into the profiled element receptacle 140 partly protrude beyond the profiled element receptacle 140 into the closing or key channel 9 and thus form a variable or variable profile for the closing channel 9. The holes for the profile element receptacle 140 are formed in more than 50% in the lock core 8 and its base part 120 and a correspondingly smaller part is formed projecting into the lock channel 9, so that a groove-shaped portion or groove portion 144 results (except the stepped bore portion 142 or also blind hole section). The length of the profile elements 130 in their 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 are not axially displaceable in the profile element receptacle 140, as soon as the lock core 8 from the cylinder wall Housing section is surrounded. The width and / or the diameter of the individual cylindrical sections 136 is / are at least partially formed differently. The individual cylindrical sections 136 are preferably integrally formed with 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 tumbler pins 10, which protrude with an end portion in the lock channel 9, transverse to the profile elements 130, at least if no key 12 is inserted into the keyway 9. The lock cylinder 1 with the lock core 8 and the key 12 are part of the locking device 100, which shows only the lock core 8 and the key 12 to illustrate the principle of action of the lock core 8.

Fig. 26 schematically shows in another perspective view of the lock core 8 of the embodiment according to Fig. 25 in isolation. The profiled element receptacles 140 have a stepped bore section 142 (not explicitly shown here) and a groove-shaped groove section 144. In the stepped bore section 142, the profile element 130 is completely surrounded, so that storage is realized in the area. From the opposite to the stepped bore portion 142 axially longer, groove-shaped groove portion 144, the different cylindrical portions 136 protrude at least partially laterally into the closing channel 9 and thus form a lateral boundary, thus a profile, for a key to be inserted into the closing channel 9. Due to the cylindrical design of the profile elements 130, a resistance between key and profile elements 130 is reduced, especially since the profile elements 130 are rotatably mounted in the profile element receptacles 140. Due to the axial fixation of the profile elements 130, the profile is fixed axially. By exchanging the profile elements 130 and / or the cylindrical sections 136, a variety of profiles which can not be changed by means of a key 12 which can be introduced into the closing channel 9 can be realized for the closing channel 9. In contrast to the locking pins 10, the profile formed by the profile elements 130 is not changed by an inserted key 12. Some of the sections 136 do not protrude beyond the edge of the profiled element receptacle 140. In this way, a complex profile for the closing channel 9 can be realized.

Fig. 27 schematically shows in a perspective view of an embodiment of the key shank 12 'with differently arranged and formed as a profile roller 137 and profile pin 138 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 Fig. 27 4, four of the five variable profile elements 130 are designed as profile pins 138 and a profile element 130 as a profile roller 137. The profile roller 137 protrudes with its lateral contour in the corresponding contour of the key 12. In this case, the profile roller 137 on different sections with different sizes diameters. On a narrow side of the key 12 recesses for tumbler pins 10 are provided. The orientation of the profile roller 137 is parallel to the orientation of the tumbler pins 10 (not shown). The orientation of the profile pins 138 is transverse to the orientation of the profile roller 137. The profile pins 138 are aligned such that one end of the profile pins 138 cooperate with each other. Intervention with the profile of the key 12 is formed. In this case, three of the four profile pins 138 are aligned substantially perpendicular to a broad side of the key 12. A fourth profile pin 138 is aligned transversely to the other profile pins 138. Due to the oblique orientation of the profile pin 138 is provided to form a closing profile with undercut S. This will be in Fig. 28 more clear.

Fig. 28 schematically shows the embodiment according to Fig. 27 in a frontal view overlooking the key tip. The fourth profile pin 138 is aligned obliquely to the other profile pins 138. In this way, a closing profile with an undercut S is realized. Thus, the embodiment after FIGS. 27 and 28 a closing profile with fixed and variable profile elements 130 ready, wherein the variable profile elements 130 partially formed as a profile roller 137 and partially as profile pins 138 are. With this embodiment, a flexible coding is ensured, with an influence on the tumbler pins 10 is reduced.

Fig. 29 schematically shows a perspective view of an embodiment of a locking device 100 with a lock cylinder 1 and a corresponding key 12 or key unit, the vast majority of profile elements as profile pin 138 (not shown here, see, eg Fig. 32 ) is trained. Externally, the embodiment differs according to Fig. 29 thus not or only insignificantly from the embodiment according to Fig. 13 , The key 12 is formed as a reversible key. Also in the Fig. 29 the lock cylinder 1 is designed as a profile double cylinder. This comprises the cylinder housing 2, which is composed of the cylinder opening exhibiting, circular in cross-section cylinder wall 4 and the radially uniformly extending from this web portion 5. In each cylinder opening a lock core 8 is arranged, in this present embodiment as a double cylinder thus two locking cores 8 are provided. The lock cores 8 are axially fixed, for example by means of the clamping ring. The cylinder wall 4 forms with its inner wall, the core bore into which the cylinder core or lock core 8 is inserted. In the lock core 8 is the radial cut keyway 9 (see also Fig. 2 or Fig. 14 . incorporated here only schematically), which is open to one side of the lock core 8. In a known manner, the lock core 8 receives at least two-part tumblers, tumbler pins, tumbler pins and / or housing pins 10, which in Fig. 29 are not explicitly shown and queried by keytank side wells of the key 12. The core-side ends of the sprung in the direction of the key channel 9 tumbler pins 10 protrude stop limited in the keyway or closing channel 9 into it. However, such tumbler pins 10, which are to be distinguished from the profile elements due to their displaceable positioning, are known, so that will not be discussed further. To the axis of rotation of the cylinder wall 4, the closing unit 40 is received in the recess 42 with the locking lug, not shown here. This is rotated upon rotation of the closing profile to the appropriate key 12 with a corresponding key profile around the axis of rotation and so realizes a closing function of the lock cylinder 1, which is well known. The key 12 has, inter alia, the key shank 12 'on which the key profile and the permutation recesses are formed.

Fig. 30 schematically shows the embodiment of the lock cylinder 1 in perspective view Fig. 29 without corresponding key 12. Accordingly, the closing profile of the closing channel 9 can be clearly seen. The embodiment does not differ externally or not significantly from the embodiment Fig. 14 , The closing profile has recesses, depressions and projections, which along a Main extension of the closing channel 9 extend and which are formed by the median plane to both sides of the plane. Over the course along the main extension of the closing channel 9, the closing profile can vary.

Fig. 31 schematically shows in a perspective view of an embodiment of the lock cylinder 1, in which an upper cylinder wall portion is removed. In this way, the closing channel 9 is visible along its main extension. How out Fig. 31 can be seen, the lock core 8 transverse to the profiled closing channel 9, in particular perpendicular thereto, profile element receptacles 140, in which profile elements 130 (see Fig. 32 ) are introduced or introduced. The profiled element receptacles 140 are designed here as receiving bores 141 and run radially in the direction of the closing channel 9, so that the receiving bores 141 open into the closing channel 9 and thus in each case an opening into the closing channel 9 is realized. In the formed as receiving holes 141 profile element receptacles 140 designed as profile pins 138 profile elements 130 are inserted (see also Fig. 32 ).

As in Fig. 32 can be seen, they are designed so that they protrude with a part in the closing channel 9 and thus represent or form part of the closing profile. More precisely, the profiled elements 130 designed as profiled pins 138 protrude into the closing channel 9 with their end formed as a tip 138b. The profiled element receivers 140 are in this case arranged partially offset relative to one another. The profile element receptacles 140 are once offset in the axial direction of the lock core 8 to each other. On the other hand, the profiled element receptacles 140 are also offset at least partially offset from one another in the radial direction and / or circumferential direction.

In particular shows Fig. 32 schematically in a partial exploded view of the embodiment according to Fig. 31 , Here, the formation of the profile pins formed as profile pins 138 profile elements 130 and the profile element receptacles 140 can be clearly seen. The profile element receptacles 140 designed as bores open into the closing channel, so that in each case an aperture 145 (see, for example, FIG Fig. 35 ) between the respective formed as a receiving bore 141 profile element receptacle 140 and closing channel 9 is formed. In the trained as receiving holes 141 profile element receptacles 140, the main extension extends transversely to a plane spanned the center plane ME of the closing channel 9, designed as profile pins 138 profile elements 130 can be inserted or inserted. The profile elements 130 embodied as profile pins 138 are embodied here as rotationally symmetrical profile elements 130, more precisely as profile pins 138 with a rotationally symmetrical cross section. The profile pins 138 have a main section 138a and a section formed as a tip 138b. The main portion 138a is formed substantially cylindrical. The tip 138b is in Diameter smaller than the main portion 138 a executed. In the Fig. 32 For example, the tip 138b is conically tapered. Trained as profile pins 138 profile elements 130 protrude only intermittently or in sections, more precisely with the tip 138b or a portion of the tip 138b in the closing channel 9 through the respective apertures 145 (not shown here). The profile pins 138 themselves are in Fig. 32 formed substantially the same. But it can also provide differently shaped profile pins 138. By a different design of the profile pins 138 different closure profiles can be realized.

The FIGS. 33 to 35 show another embodiment in the same or at least similar views as in FIGS FIGS. 29 to 32 , The embodiment according to the FIGS. 29 to 32 concerns reversible key-lock cylinder combinations. Here, an orientation of the closing channel 9 and the key 12 during insertion is shown horizontally. An orientation of the closing channel 9 and the key 12 may also be vertical in reversible key-lock cylinder combinations in another embodiment. In a conventional or conventional key 12, the closing channel 9 is vertically aligned. The reversible key 12 according to FIGS. 29 to 32 can also be turned by 180 ° about its longitudinal axis in the closing channel 9 introduce. 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. FIG. 34 corresponds to FIG. 33 without key 12.

Fig. 33 schematically shows in a perspective view of an embodiment of a closing device 100 comprising the lock cylinder 1 and the corresponding key 12. In the Fig. 33 the lock cylinder 1 is designed as a profile double cylinder. This comprises the cylinder housing 2, which is composed of the cylinder opening exhibiting, circular in cross-section cylinder wall 4 and the radially uniformly extending from this web portion 5. When trained as a double cylinder, a lock core 8 is arranged in each cylinder opening, for example by means of the clamping ring, similar to in FIGS. 29 and 30 , is axially fixed. The cylinder wall 4 forms in each case with the inner wall a core bore into which in each case the corresponding cylinder core or lock core 8 is inserted. In the lock core 8 of the radially cut closing channel 9 (see Fig. 34 ; incorporated here only schematically), which is open to one side of the lock core 8. In a known manner, the lock core 8 takes at least two-part locking elements, tumbler pins and / or housing pins 10 (see, inter alia Fig. 44 ), which are in Fig. 33 are not explicitly shown and queried by keytank side wells of the key 12. The core-side ends of the sprung in the direction of the closing channel 9 tumbler pins 10 protrude stop limited in the closing channel 9 inside. Such tumbler pins 10 are however, known so that it will not be discussed further. Around an axis of rotation of the cylinder wall 4, the closing unit 40 is received in the recess 42 with the locking lug not explicitly shown here. This is upon rotation of the closing profile to the appropriate key 12, that is, with the key 12 with corresponding key profile, rotated about the axis of rotation, thus realizing a closing function of the lock cylinder 1, which is well known.

Fig. 34 schematically shows the embodiment of the lock cylinder 1 in perspective view Fig. 33 without corresponding key 12. Accordingly, the closing profile of the closing channel 9 can be clearly seen. This has recesses, depressions and projections, which extend on the one hand along a main extension of the closing channel 9 and which are formed by a median plane to both sides of the plane. Over the course along the main extension of the closing channel 9, the closing profile can vary.

Fig. 35 schematically shows in a sectional perspective view of an embodiment of the lock cylinder 1, in which the upper cylinder wall portion is removed. In this way, the closing channel 9 is visible along its entire main extension. How out Fig. 35 and also out Fig. 31 it can be seen, the cylinder core 8 in addition to the profiled closing channel 9 profile element receptacles 140, in which profiled elements formed as profile pins 138 130 can be introduced or are introduced. The profile element receptacles 140 are formed here as receiving bores 141. These lead into the closing channel 9, so that an opening to the closing channel 9 is realized. In the receiving holes 141 formed as profile pins 138 profile elements 130 are inserted. These are designed so that they protrude with a part, more precisely with the end formed as a tip 138b in the closing channel 9 and thus represent or form part of the closing profile.

Fig. 36 schematically shows a side view of an embodiment with shown different view or sectional planes. A sectional plane WW extends through a remotely to a front or Schlüsseleinsteckseite the lock core 8 approximately centrally through the rearmost element element receptacle 140. A sectional plane VV runs approximately centrally through the third leading profile element receptacle 140. A section plane TT runs approximately centrally through the zweitvorderste profile element receptacle 140th A Section plane UU runs approximately centrally through the foremost profiled element receptacle 140. A plane of view RR runs along a front side F of the closing core 8.

Fig. 37 schematically shows the section TT of the embodiment according to Fig. 36 , The cylinder wall 4 of the cylinder housing 2 surrounds the lock core 8 in full. In that Locking core 8 are the closing channel 9 and one side thereof provided a profile element receptacle 140 in the form of a receiving bore 141. In the profile element receptacle 140, a profile element 130 in the form of a profile pin 138 is provided. In this case, the profile element receptacle 140 and, accordingly, the profile pin 138 is arranged slightly off-center about the offset H to the vertical center line M. The tip 138b of the profile pin 138 protrudes by an offset G reset with respect to the horizontal center line N in the closing channel. 9

Fig. 38 schematically shows the section UU of the embodiment according to Fig. 36 , In the two above shown profile element receptacles 140 different long profile elements 130 are added in the form of profile pins 138. With their opposite the tip 138 b located the end of the profile pins 138 to the cylinder wall 4, so that the profile elements 130 are fixed in the axial direction. While the two upper profile elements 130 and the corresponding profile element receptacles 140 are aligned approximately parallel to the vertical center line M, the lower profile element 130 or its profile element receptacle 140 is aligned transversely to the center line M and the center line N. In this way, an undercut closing profile (undercut S) can be realized. The closing profile of the closing channel 9 varies over its main extension direction. Due to the different profile elements 130, an exchangeable closing profile section is formed. It can be clearly seen that the profile elements 130 protrude into the closing channel 9 through the corresponding apertures 145. By appropriately filling or releasing the apertures 145 by the replaceable profile elements 130, a variable profile section is realized in addition to a fixed or fixed profile section of the closing channel 9.

Fig. 39 schematically shows the section VV of the embodiment according to Fig. 36 , Again, it can be clearly seen that the closing profile along the main extension direction of the closing channel 9 varies. In this way, a variable closing profile is realized. The profile element 130 is offset by the amount H + x2 offset from the center line M and by the amount G + y2 offset from the center line N. arranged. Here too, the profile element 130 adjoins the cylinder wall 4 with the end remote from the tip 138 b.

Fig. 40 schematically shows the view WW of the embodiment according to Fig. 36 , In Fig. 40 the profile element 130 is offset by the amount H + x3 to the vertical center line M and the amount G + y3 to the horizontal center line N offset. Here too, the profile element 130 adjoins the cylinder wall 4 with the end remote from the tip.

Fig. 41 schematically shows various dependencies of the arrangements of two profile elements 130. The profile elements 130 have the same length here. Both profile elements 130 adjoin the cylinder wall 4 with the end remote from the tip 138b. The following calculation results for the depth of the profile rib to be formed by the profile elements 130. Y represents the offset, in particular the axial and / or vertical offset, of equally aligned profile elements 130 between the respective front tip ends. This results from B1 - B2. B respectively represents the length of a profile element 130 from its tip 138b to the midpoint of a rounding at the other end. The rounding at the other end has the radius r. The diameter of the lock core 8 is D. The distance, in particular the horizontal distance, of the center lines of the two profile elements 130 to each other is X. The distance, in particular the horizontal distance, of the respective profile element center line to the vertical center line of the lock core is A, thus A1 for the first profile element and A2 for the second profile element. The relationship Y = B1 - B2 yields Y = √ ((D / 2-r) ² - (A1) ² ) - √ ((D / 2-r) ² - (A1 + x) ² ). In this way, a specific closing profile can be defined for the same profile elements. The FIGS. 41 to 45 clarify this calculation basis.

Fig. 42 schematically shows an arrangement of a plurality of profile elements 130. The profile elements 130 are formed as profile pins 138. The illustrated profile pins 138 are the same. In particular, the profile pins 138 have a same longitudinal extent. With a tip 138b extending from a main portion 138a, each profile pin 138 projects into the closing channel 9. The profile pins 138 are circumferentially offset from each other. At the same time, the profiled pins 138a, with the end remote from the tip 138b, adjoin the cylinder wall 4 surrounding the lock core 8. As a result, the profile pins 138 protrude differently far in the direction of the closing channel 9. The basic orientation or orientation of the profile pins 138 is in FIG Fig. 42 horizontally, thus perpendicular to a closing channel wall and / or parallel to a closing channel bottom.

Fig. 43 schematically shows another arrangement of a plurality of profile elements 130. The profile elements are as in Fig. 42 formed, namely as profile pins 138 with the same longitudinal extent. The difference in Fig. 43 is that the profile pins 138 transverse and / or rotated to those in Fig. 42 are aligned here about 45 ° rotated.

Fig. 44 schematically shows a closing channel profiling with Zuhaltestift 10. The tumbler pin 10 projects approximately perpendicular to a side wall of the closing channel 9 in this. In this case, the tumbler pin 10 is resiliently mounted, so that when inserting a key 12 (not shown here) evades into the closing channel 9 and in accordance suitable profiles a rotation of the lock core 8 releases. In addition, four profile pins 138 are provided, each projecting with a different length part of the tip 138 b in the closing channel 9. The profile elements 130 are formed of equal length and lie with the tip 138 b opposite end of the cylinder wall 4 at. This results in a horizontal offset x of the profile elements, a horizontal offset of the tips 138b to each other of y, which is calculated according to the above formula.

Fig. 45 schematically shows another view of a conventional locking channel profiling with tumbler pin. Here is the profile Fig. 44 shown enlarged. In the illustrated embodiment, the closing channel 9 is arranged vertically.

Fig. 46 schematically shows in a side view scanning a key profile at a key 12 without undercut S. The profile element 130, 138 is approximately horizontally aligned. With its tip 138b, the profile element 130, 138 engages in the corresponding recess, which is partially complementary to the tip 138b, of the key profile.

Fig. 47 schematically shows in a side view scanning a key profile in a reversible key 12 without undercut S. Here, the orientation of the profile element 130, 138 is vertical. Otherwise, the embodiment is similar to that of FIG Fig. 46 , The profile pin 138 has the tip 138b and the main portion 138a. At the end opposite the tip 138b, the profile pin 138 has a rounded portion 138c.

Fig. 48 schematically shows in a side view a scanning of a key profile in a key 12 including queries of an undercut S. Here is unlike Fig. 46 the orientation can be seen transversely to a horizontal. Due to the oblique orientation, a kind of undercut S is generated, which corresponds to an undercut key profile.

Fig. 49 schematically shows in a side view scanning a key profile 12 at a reversible key 12 including queries of an undercut S. The execution essentially corresponds to the Fig. 48 , except that the execution is rotated by 90 °.

Fig. 50 schematically shows in a side view scanning a key profile 12 by means of two profile elements 130,138 including queries of an undercut S. A profile element 130, 138 is aligned for an undercut. The other profile element 130, 138 is aligned for a profile without undercut. Fig. 22 does it clearly that undercut profiles are easily combinable with undercut-free profiles or profile sections.

51 schematically shows in a perspective view of an embodiment of a lock core 8 with a key 12 in the uninstalled state, the lock core 8 has a closing channel or keyway 9, which extends parallel to a center plane ME approximately radially and penetrates the lock core 8 in one direction, so that a slot-shaped closing channel 9 results. The closing channel 9, more precisely the Rohschließkanal, is thus approximately cuboid, possibly formed with a solid profile, which also embodiments may result in the radial and / or axial direction tapering or varying contour. The lock core 8 has a front region 110 and a base part 120. Holes for tumblers 10 (not shown here) are formed transversely to the slot-shaped closing channel 9, here approximately perpendicular to a median plane ME. The front portion 110, which is arranged coaxially with the base part 120, thus projecting circumferentially over the base part 120 in the radial direction and thus serves, for example, as a stop for the cylinder (-core) housing 2 or the cylinder wall 4 (here not shown). In the radial extension direction of the closing channel 9 radially extending profile element receptacles 140 which open radially on one side into the closing channel 9 are provided, which penetrate the base part 120 to the closing channel 9 on one side. The radial recesses are opened in a direction to the closing channel 9 and formed for receiving profiling profile elements 130. The radial recesses are referred to as profile element receptacle 140 accordingly. The profile element receptacles 140 are spaced from each other and thus separated accordingly. In this case, the profile element receptacles 140 are offset from one another. The orientation of the profile element receptacles 140 is the same, that is aligned over the circumference perpendicular to the closing channel 9. As a result of the offset, the radial lengths of the profiled element receptacles 140 are of different lengths from the closing channel 9 to the surface of the base part 120. In the axial direction of the base part 120, thus the insertion direction of the key 12, the profile element receptacles 140 are arranged equidistant from each other. The profile element receptacles 140 are formed as holes 141. More specifically, the length of the profile elements 130 is designed such that a predetermined part of the tip 138b protrudes into the closing channel 9 as a profile-forming section in the profile element receiving 140 recorded profile elements 130 at least partially in the closing channel. The profile elements 130 are preferably cylindrical, more precisely than profile pins 138. In this case, the profile elements 130 have a cylindrical main sections 138a with a constant diameter here. A cylindrical section, more precisely an end or a tip 138b of the profiled pin 138, is designed so that the latter via the profiled element receptacle 140 into the closing channel 9 partially protruding and so the closing channel 9 through this supernatant is a profile. The tip 138b is arbitrarily formable, but preferably has a smaller diameter than the main portion 138a. The profile elements 130 are preferably rotatably mounted in the profile element receptacle 140 so that they can rotate in contact with a corresponding, profiled key 12 with the insertion movement of the key 12. Preferably, the profile elements 130 have a friction-reducing layer or the like, so that they are even more easily rotatably mounted in the profile element receptacle 140. The profile elements 130 can be exchangeable and / or used without tools in the profile element receptacle 140. In this way, in a cylinder core 8 different profiles for a closing or key channel 9 can be realized by using different profile elements 140. The cylinder core 8 is preferably formed integrally with the exception of the profile elements 140 and the tumbler pins 10. Thus, the base portion 120 is formed integrally with the front portion 110.

The profiled elements 130 inserted into the profiled element receptacle 140 partly project beyond the profiled element receptacle 140 into the closing channel 9 and thus form a variable or variable profile for the closing channel 9. The holes for the profile element receptacle 140 are formed projecting into the closing channel 9. The length of the profile elements 130 in their main extension direction (axial direction) substantially corresponds to the length of the profile element receptacle 140 in its main extension direction (axial direction) with the exception of the profile-forming part, so that the profile elements 130 abut in one direction on the cylinder wall 4 with the key inserted. The profile elements 130 and the profile pins 138 protrude with one end, more precisely the tip 138b or a profile-defining or forming part of the tip 138b in the closing channel 9, analogous to the tumbler pins 10, which also project into the closing channel 9 with an end portion. The tumbler pins 10 protrude parallel to the profile elements 130, at least if no key 12 is inserted into the keyway 9, in the closing channel 9. The lock cylinder 1 with the cylinder core 8 and the key 12 are part of the locking device 100, here to illustrate the principle of action the lock core 8 shows only the lock core 8 and the key 12.

Fig. 52 schematically shows in another perspective view of the cylinder core 8 of the embodiment according to 51 in isolation. The profiled element receptacles 140 have a stepped bore section 142 transversely to the closing channel 9. In a stepped bore portion 142 adjacent to the Schließkanl 9 and opening into the closing channel 9, the tip 138 b and the thinner end of the profile pin 138 is arranged. With the opposite to the stepped bore portion 142 axially longer tip 138 b protrude the ends of the respective profile pins 138 at least partially into the closing channel 9 and form Because of the cylindrical design of the profile elements 130, a resistance between key and profile elements 130 is reduced, especially since the profile elements 130 are rotatably mounted in the profile element receptacles 140. The stepped bore portion 142 forms opposite the remaining portion of the bore 141 at the transition a shoulder 143 or a shoulder on which the profile element 130 rests in the transition from the main portion 138a to the tip 138b. The profile element 130 is thus axially fixed by the shoulder 143 on the one hand and the surrounding cylinder wall 4 (not shown here). Due to the axial fixation of the profile elements 130, the profile is fixed axially. By replacing the profile elements 130 can spanless various realizable by a insertable into the lock channel 9 key 12 profiles for the closing channel 9 realize. In contrast to the position of the tumbler pins 10, the profile formed by the profile elements 130 is not changed by an inserted key 12 in the position.

Fig. 53 schematically shows in a perspective view enlarged a section of an embodiment of a key profile with undercut S. In the key profile sections undercuts S are formed in the profile. The corresponding profile is complementarily imaged by the profile elements 130 in the lock core, as in Fig. 26 and 27 shown.

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.
