    The invention relates to the field of locking systems and in particular a key and the associated blank, a key suitable for locking cylinder and a locking system which has a novel key and a lock cylinder according to the invention.
    A central task of the locking technology is to provide locking systems that reliably restrict access to or access to an object to a well-defined group of authorized persons. In particular, the challenge for mechanical locking systems is that, on the one hand, a sufficient number of different authorizations can be granted by permitting a sufficiently high number of permutations for a mechanical coding of the key and, on the other hand, maximizing the cost of unauthorized access.
    Locking cylinders of mechanical locking systems generally have a component mounted in a housing-mounted component ("stator") and rotatable about an axis ("rotor, cylinder core"), the rotation of which releases the access or access, for example by Actuation of an output element, which is in operative connection with a bolt, wherein optionally the coupling with an output mechanism may be linked to conditions. The release or non-release of a rotation of the rotor in the stator can be effected in particular by the interaction of tumblers and Gegenzuhaltungen with a suitable mechanical coding of the key. This works so that pairs of tumblers and counter-tumblers are arranged in aligned in the initial state holes in the rotor and in the stator pairs, the ends of the tumblers protrude from the rotor into the keyway. By inserted into the keyway appropriately coded key the tumbler Gegenzuhaltungspaare against a spring force as far pushed out (or not pushed) that their interface is on the interface between the rotor and stator, so that they rotate the rotor relative to the stator ( at which rotation the tumblers rotate in the rotor and the Gegenzuhaltungen remain in the stator) no longer oppose.
    The number of possible permutations is defined on the one hand by the number of coding elements (e.g., coding holes) which can be arranged on a key, and on the other hand by the number of states detectable per coding element.
    The maximization of the cost of an unauthorized access includes in addition to structural and material engineering measures to prevent too simple copying of the key with a. So far, the technical hurdles to be overcome in order to copy a (security) key have been and still are quite high, so that there are only a few suppliers who produce a copy of such a key with the necessary accuracy and tolerances can. A majority of these few vendors participate in a more or less voluntary control and deny unauthorized copying of keys.
    The rapid progress in the fields of 3D printing, materials science, scanners and data processing programs can now fear the emergence of new copying possibilities.
    This emerging problem can be counteracted by incorporating into the bowl additional security features that can not be copied by 3D printers or similar means perhaps available to the broadest segments of the population, e.g. in the form of moving parts, the concrete designs of which are decisive for the interaction with the locking cylinder.
    In the field of locking systems introduced into the key elements are already known. These serve primarily to increase the number of coding elements and thus the number of possible permutations. Often, the elements used have properties that adversely affect the reliability and life of said keys. Thus, EP 0 436 496 B1 describes a key whose shaft has a thicker cut-in area and a thinner profile area. In the profile area circular cylindrical styli are introduced in transverse (i.e., the two flat sides connecting) openings. By varying the length of the styli, which i.a. exceeds the width of the profile area, it is possible to increase the closure difference. The styli essentially assume the function of a (movable) spacer. Further, the key shown in EP 0 436 496 B1 is susceptible to jamming of the movable member, which markedly affects the reliability in use, and the tactile pins projecting beyond the profile portion favors wear and damage of the key.
    Also, the movable element shown in EP 1 336 022 B1 leads to an increased susceptibility to damage, e.g. by pollution. The movable element is a ring, which is introduced into an oblique slot inserted into the shaft. Also, this ring acts as a spacer and serves to increase the variety and possible combinations of key encodings.
    It is an object of the invention to provide a key, a key blank, a locking cylinder and a locking system to provide protection against a security breach by 3D printing of the key by incorporating additional security features.
    It is a further object of the invention that the additional security features have no negative impact on the reliability of the inventive devices. This concerns in particular the key or key blank, in which the additional security features are to be designed so that the probability of malfunction is significantly reduced by, for example, tilting or wear.
    These objects are achieved by the invention as defined in the claims.
    The key according to the invention or the key blank according to the invention are provided in particular for mechanical locking cylinders (purely mechanical or combined mechanical-electronic locking cylinders) of the type described above, in which a stator and a rotatable relative to this rotor pairs of tumblers and Gegenzuhaltungen.
    Hereinafter, the additional security features are discussed as features of a key according to the invention. All these additional security features can also be integrated into a blank according to the invention, which is processed at a later time by attaching mechanical codes to a finished key.
    The inventive key is formed, for example, as a flat reversible key, i. the shank is substantially flat and has coding holes at least on the flat sides. At least the shaft is symmetrical with respect to a rotation through 180 °. Apart from the security features described below and apart from a possible electronic module and its housing, the key according to the invention can be made in one piece. In particular, all features of the key, e.g. Shank, Reide, encodings, etc., which are not related to the security features described below, are manufactured with the current, state of the art manufacturing methods.
    An essence of the invention is to complicate the 3D-printer based key copying by adding movable elements in the area of the key shank. When inserting a key according to the invention into a lock cylinder, the movable element interacts as known per se with two tumbler pairs, wherein for each tumbler counteracting pair exactly one position defined by the intrusion of the tumbler into the key channel causes the interface between tumbler and counteracting a tumbler Gegenzuhaltungspaares coincides with the shear line between the rotor and stator, whereby a tumbler Gegenzuhaltungspaar, which occupies this one position, the rotation of the rotor relative to the stator no longer inhibits.
    In a preferred embodiment, a movable element is introduced into a bore which connects continuously a flat side of the shank with the other flat side. Element and bore are designed in shape and dimensions so that on the one hand tilting of the movably mounted element is prevented and on the other hand, the hurdle for a replica is further increased. This can be realized in that the element has a central part and at least two, often Favor at least three, radially arranged guide parts, which cause the shape of the element is not circular cylindrical. In one embodiment of the movable element, this has four guide parts, which are arranged around the central part, that the element has a cross-shaped cross-section. However, embodiments are also conceivable which have three, five or more guide parts, so that an overall star-shaped cross-section can result. The cross section perpendicular to the axis of the bore can be unchanged from one flat side of the shaft to the other. However, the cross section of the element can also vary from one flat side of the shaft to the other. This is particularly the case when the element has means for determining a maximum deflection of the element. Such a maximum deflection can for example be achieved by the element is designed so that this pushes at two points, preferably in each case one in the region of the two flat sides, to a further deflection preventing part. Alternatively, such a part can also be integrated in the bore itself in combination with a corresponding shape of the element.
    By the inventive approach a dilemma is solved, which exists in connection with moving elements in the key. The procedure is based on the knowledge that such an element can only be guided over a very limited guide length in the hole provided for this purpose. This is because, on the one hand, the thickness (thickness) of the key shank, which corresponds to the maximum guide length, is generally only a few millimeters. On the other hand, the expansion of the movable element along the shank plane can not be arbitrarily small, if the mechanical stability and function are to be ensured. This inevitably leads to an unfavorable ratio between length (dimension in the direction of the direction of movement) of the movable element on the one hand and expansion along the shank plane (eg diameter) on the other. Without the measures according to the invention, this would lead to a reduced reliability due to canting of the element. In mechanical engineering, for example, the maxim applies that the ratio between the guided length and the guided width should be greater than 1.3 to 1.5 in order to be able to largely avoid canting of an element. Transferred to the moving element key or blank, this would entail, without special precautions, a width (diameter) of the element, both in terms of stability and handling of the element, but also in terms of its interaction with corresponding tumbler and counteracting pairs would be very unfavorable.
    The movable element in the inventive key solves this dilemma of a maximum possible, reliably guided width by the element has guide parts, which define a reduced compared to the diameter of the movable element guide width.
    In a preferred embodiment, the maximum deflection of the element in the direction of the bore axis by its interaction with per flat side at least one stop, which limits the movement in the corresponding axial (with respect to the bore axis) direction and which in the corresponding flat side the shaft is integrated, limited. These stops may be formed as stop members, which in turn are introduced into a bore, wherein bore and stop members are designed so that the stop members occupy a defined position. This can e.g. can be realized by the stop members are pin-shaped and have a head, the heads of the stop members (hereinafter called stop heads) rest on integrated into the bore of the stop parts projections. These projections can be designed annular and realized by reducing the diameter of the bore. The facing in the direction of the flat side of the shaft surfaces of the stop members are preferably flush in their final position with the flat sides themselves. In this embodiment, the stop heads protrude partially into the bore of the element and thus prevent a correspondingly shaped movable element falls out of the hole. The stop members are screwed into their bore, glued, pressed or otherwise fixed therein.
    In a further embodiment, the stops are formed by the completion of the hole for the element itself, e.g. realized by a continuous or stepped narrowing towards the flat sides. These restrictions can be continuous, e.g. annular, or interrupted, e.g. a single or multiple extensions, be designed. The constrictions may be the result of a near-hole embossing or other treatment of the flat sides of the shaft.
    In one embodiment, the movable element has a cross-section perpendicular to the axis of the bore, which changes in function of the position along the bore axis. This change in cross-section is designed so that the element in combination with at least one stop can only move up to a maximum deflection along the axis of the bore. For example, the element may have recesses at least against the stops, which allow movement along the axis of the bore until a non-recessed part of the element comes into contact with a stop. Such recesses may also be made in other regions of the movable element. In particular, all guide parts can have the same recesses, regardless of whether they interact with a stop or not.
    Towards the flat sides of the shank, bores, movable element and stops / abutment parts are preferably made so that they complement each other to a large extent, except for any tolerances, in order to impair the functionality of the movable element, e.g. through pollution, to prevent. In particular, the guide parts are guided on both sides accurately through corresponding wall sections of the bore.
    It is an important finding in connection with the present invention that with the help of the above-mentioned leading parts the risk of tilting and thus a defect of the closing mechanism, in the worst case during the opening or closing process, can be greatly reduced. This risk can be further reduced if the dimensions of element, guide parts and holes are coordinated. The relevant dimensions are the maximum length of the movable element or the guide parts in the direction of the axis of the bore and the widths of the leading parts. The latter are the dimensions of the considered guide tangent and perpendicular to the axis of the bore. It has been found that ratios between the length of the element and the widths of the guide parts of greater than 1 are advantageous. Particularly advantageous embodiments are those in which these ratios are greater than 1.3 or greater than 1.5. If the leading parts do not extend over the entire length of the element, this condition (ratio of minimum 1, 1.3 or 1.5) can also apply to the length of the guide parts in relation to their width. If the width is not constant as a function of the radial position-for example, because the guide parts taper outward-this condition applies, for example, to the mean width.
    In a further embodiment according to the invention, the guide of the element can be limited to side surfaces of the respective guide parts. This can be achieved by the bore being designed so that there are spacings between the radially outer end of the guide parts and the wall of the bore, or at least that the tolerances are greater.
    With a view to a possible wear of the components of the security feature, it may be advantageous if the length of the movable element does not exceed a thickness of the shaft so that the element can be brought into a position in which no part is not key inserted into the lock cylinder protrudes beyond the plane of the two flat sides of the shank, ie if the movable element can pull back on both sides at least flush with the two flat sides in the shaft when a force is applied to the element. The maximum length of the element should therefore be less than or equal to the shaft thickness. Additionally or alternatively, it may be provided that the ends of the element are formed so that the element retracts into the shaft even at an angle to the axis of the bore or even perpendicular to this forces, for example by the ends of the element rounded or bevelled are.
    The security feature described may be located in any position on the shaft of the key. In one embodiment according to the invention, the safety feature described is mounted on the shaft towards the rear, for example at the level of or behind the first conventional coding. The security feature is preferably, but not necessarily, centered on the shaft.
    An inventive key for the purpose lock cylinder has a stator fixed to the housing and located in the stator, by using a suitable coding having key rotatable about an axis rotor. Further, a keyway is formed on the rotor, which is accessible from the outside via the associated key opening. In the stator and in the rotor a number of tumbler Gegenzuhaltungspaaren are arranged, of which at least two tumbler Gegenzuhaltungspaare interact with the movable element with fully inserted in the keyway key. All Gegenzuhaltungen the tumbler Gegenzuhaltungspaare are burdened by one spring.
    The lock cylinder can be designed as a single cylinder or as a double cylinder. In addition to the mechanical security features described here (tumblers interacting with the movable element, conventional tumblers), it can also optionally have electronic / electromechanical security features.
    In one embodiment of the lock cylinder mounted in the lock cylinder and interacting with the movable element tumblers are designed so that at least one of these tumblers must be pushed by a keyhole engaging behind the lot of key from the keyway towards the stator, i. the key must be locally wider than the keyhole opening to solve the obstruction caused by this tumbler counter-locking pair. The movable element must therefore be brought into a position in which it protrudes from the flat side of the key out. Since no key can be inserted into the lock cylinder, which is wider than the width of the keyhole, it is thus ruled out that a key without the corresponding movable element leads to an unlocking of the said tumbler counteracting pair.
    In one embodiment, this active pushing back a tumbler is achieved in that two differently loaded tumbler Gegenzuhaltungspaare interact on the movable element, said tumbler Gegenzuhaltungspaare are designed so that the weaker loaded tumbler Gegenzuhaltungspaar by said intervening batch for Unlocking must be pushed towards the stator, while the more heavily loaded tumbler Gegenzuhaltungspaar must move to unlock in the direction of the rotor (or keyway). In this case limits a stop (either the key or a tumbler Gegenzuhaltungspaares) caused by the more heavily loaded Zuhaltungs-Gegenzuhaltungspaar deflection of the movable element out of the key shaft addition. For unlocking both participating tumbler Gegenzuhaltungspaare occupy a predefined position, which is only given if the dimensions of the tumbler Gegenzuhaltungspaare and the movable element and the positions of the effective stop cooperate in the intended manner.
    The tumblers are loaded in embodiments mounted on the housing of the cylinder springs. In a preferred embodiment of the springs, the ratio of the two associated with the movable member springs of the order of two to one.
    The spatial arrangement of the two tumbler Gegenzuhaltungspaare can be configured in various ways. So they can face each other and stand perpendicular to the flat sides. However, it is also possible for one or both tumbler counteracting pairs to act on the movable element at a non-normal angle and / or not to oppose one another. Furthermore, it is possible that the more heavily loaded tumbler counteracting pair is formed only by the tumbler itself (and the spring) and is located completely in the rotor.
    A closing system according to the invention has a key according to the invention as well as a locking cylinder suitable for this purpose.
    The interaction between the movable member and the corresponding tumblers happens at fully inserted into the key channel key on their contact points. These are given, for example, by the end faces of the central part of the element and the key side end faces of the tumblers which are. The latter can be designed so that they take into account the shape of the element and the relative position of the respective tumbler to the key channel. Depending on the configuration of the end surfaces forming the contact points, the interaction takes place via a punctiform, linear or flat contact. Embodiments are also possible in which the characteristics of the two contact points differ.
    The contact points can extend parallel to the flat sides of the shaft. On the element side, these contact points preferably do not coincide with the mentioned recesses originating from the interaction with the stops and / or not with chamfers or rounded portions.
    Further embodiments will be apparent from the dependent claims. In this case, features of the claimed key can be combined with those of the claimed lock cylinder and vice versa.

    Hereinafter, the operation and implementation of the invention will be shown with reference to various exemplary embodiments. It should be understood that the invention is not limited to these embodiments, but includes other embodiments consistent with the claims.
    1a shows an inventive key 1, which has a Reide 2, an insertion limit 3, a shaft 4 and an integrally mounted in the shaft, movably mounted element 5. The key is designed as a flat reversible key, i. the shank is substantially flat and has coding holes at least on the flat sides. At least the shaft 4 is symmetrical with respect to a rotation through 180 °.
    The key 1 also has codes 6 in the form of holes of different depth and / or width.
    In the embodiment shown, the movably mounted element 5 has four radially projecting from a central part 7 (with respect to an axis 9 of the bore 10, in which the movable element is guided, see Fig. 1b, 1c), on both sides guided leadership games 8 on. The element 5 is inserted into the through hole 9 of the shaft, wherein the movement of the element along the axis 10 of the bore 9 is bounded on both sides of the shaft by a respective stop 11.
    Further, in the embodiment shown, the element 5 is at the rear end of the shaft, i. towards Reide 3 out, in particular behind the rearmost coding 6, attached. However, the element can be attached anywhere on the shaft of the key without affecting functionality.
    Fig. 1b shows a cross section along the drawn in Fig. 1a plane A-A. The movably mounted element 5 is guided through the lateral boundary of the bore 9 along the axis 10. A situation is shown in which the element 5 assumes a position in which the geometric center of the element along the axis of the bore is not in the middle between the two flat sides 16.1-16.2 of the key. As a result, the element protrudes beyond a flat side, although the length 12 of the element along the axis of the bore is equal to the thickness 15 of the shaft.
    Fig. 1c shows a cross section along the drawn in Fig. 1a plane B-B, in which the realized as a constriction of the bore 9 stops 11 are visible.
    FIG. 2 shows a detailed view of the embodiment according to FIGS. 1a-1c, in which the movable element 5 is seen particularly well. Further, in Fig. 2, the widths 13.1-13.4 and radial expansions 14.1-14.3 of the guide parts 8 are located. The radial extent of the fourth guide section is not apparent from FIG. 2 due to the stop designed as a narrowing of the bore. The different leading parts can differ in their widths and radial dimensions. In the illustrated embodiment, the guide parts each have identical widths and identical radial dimensions, wherein the width does not have to correspond to the radial extent.
    The respective dimensions and the arrangement of the guide parts are chosen so that they prevent tilting of the element during a movement along the axis 10 of the bore within the predetermined tolerances, i. E. that the ratios between the length of the guide element along the axis of the bore and the widths of the guide parts is greater than 1.5. Furthermore, two non-mutually parallel axes of the element are guided by the guide parts, wherein one of the angles between the at least two axes is preferably 90 ° or the guide parts are arranged symmetrically at an angle of 360 ° divided by the number of guide parts.
    In the detailed view shown in Fig. 2, the element 5 has four guide portions 8, which are arranged so that the element has a cross-shaped cross-section. Furthermore, spacings 19 between the radially outer side end surfaces and the wall of the bore are shown, which result in that the guide parts 8 are each guided only along their side surfaces.
    In a further embodiment, the element has three guide parts, which are preferably arranged at an angle of 120 ° to each other.
    Furthermore, the embodiments shown in Figs. 1 and 2 are characterized in that the maximum length of the element along the axis 10 of the bore 9 is identical to the thickness 15 of the shaft, i. The element does not protrude beyond the flat sides 16.1, 16.2 with appropriate centering along the bore.
    The guide parts shown in Fig. 2 have a recess 17 formed by a chamfer towards the outside against the central part 7 of the element. Thanks to these recesses 17, it is possible to integrate at least one stop in the two flat sides of the shaft in order to limit the movement of the element along the axis of the bore. In Fig. 2, the stops are the result of embossments 11 made on the flat sides of the shank in the vicinity of the bore. The integrated in this way stops are flush with the flat sides of the shaft.
    The bevels of the guide parts also have the function to allow an effortless insertion of the key in the keyway by the tumblers are pushed backwards by the slope.
    Fig. 3 shows an exploded view of the embodiment of a key according to the invention according to FIGS. 1 and 2, in which the element 5 has not yet been introduced into the bore 9. After introduction of the element in the continuous bore stops, which limit the movement of the element along the axis 10 of the bore 9, formed in a further step. This happens, for example, by embossing designed to that effect, which are incorporated in the two flat sides of the shank in the immediate vicinity of the bore.
    Fig. 4a shows an exploded view of a key 1 of an alternative embodiment. This has shaft-mounted, originally separate stop members 18, which form the stops of the felt movement of the element 5, by being introduced into a separate bore 23 for the stop members. Furthermore, an element 5 designed with respect to the stop members 18 is shown, which differs slightly from the embodiment of FIGS. 1a-2.
    4b and 4c show two cross-sectional views representing a possible embodiment of the interaction between the movable element 5 and the stop members 18. The stop members 18 have a head 21 and a body 22 and are in the separate bore 23 (bore of the stop members) can be pressed, which varies in diameter so that it has an area for the head and one for the body. In this case, the hole for the stopper parts in the head area overlaps the bore for the element 5. In the embodiment shown, the element is provided against the stop members with recesses 24, which allow the element to be defined to a maximum, by the dimension of the recesses Deflection to move along the axis of the holes. The maximum deflection is achieved as soon as the head of one of the two stop parts comes into contact with an ascending step 25 defining the recess. The stop members may be screwed, glued, pressed, soldered, welded or otherwise fixed in the bore. Fig. 4b shows the situation with centered, i. not along the axis 10 of the bore 9 deflected element. In Fig. 4c, the position of the element 5 is shown close to the maximum possible deflection.
    5 to 7 show the mode of operation of a key 1 according to the invention in cooperation with a locking cylinder 30 according to the invention. FIG. 5 shows a possible embodiment with a matching key completely inserted into the locking cylinder. In the embodiment shown, the movable element 5 interacts with two tumblers 31, 32 which are loaded to different degrees by the two springs 33, 34. The spring 33 with the larger spring constant pushes the associated first tumbler 31 into the rotor 36, including the corresponding counter-tumbler 35, as a result of which the movably mounted element is pushed along the axis of the bore in the direction of the flat side 37 facing away from the first tumbler 31. This in turn pushes the second tumbler 32 loaded by the spring 34 with the smaller spring constant in the direction of the stator. In the configuration shown, the movement comes to a standstill as soon as a state is assumed in which the first tumbler 31 presses against the tumbler 38. Alternatively or additionally, the movably mounted element 5 can press against one of the abovementioned stops which limit the movement of the element 5 in the shaft. Springs, tumblers, stops and movable element are designed so that in said state, the dividing lines between the two tumblers 31, 32 and the associated Gegenzuhaltungen 35, 39 coincide with the shear line 40 between the rotor 36 and stator 41 and the rotor are rotated can.
    Fig. 6 shows the situation in which no key has been inserted via the key opening 47 in the lock cylinder 30. The springs 33, 34 press on the Gegenzuhaltungen the two tumblers so far into the rotor 36 and thus into the keyway 42 into it as the Zuhaltungsanschläge 38, 43 allow. In the embodiment shown, the tumbler stops are set so that the dividing line between more heavily loaded tumbler 31 and associated Gegenzuhaltung coincides with the shear line 40, if the tumbler 31 rests on the tumbler 38. This tumbler Gegenzuhaltungspaar thus leads to no obstruction. In contrast, the resting of the weaker loaded tumbler 32 on the tumbler 43 causes the Gegenzuhaltung 39 protrudes into the rotor, thus providing an obstruction 44.
    Fig. 7 shows the situation with a not completely on the keyhole 47 inserted into the lock cylinder 30 (matching) key, or even a fully imported key that has no coding at the point of attack of the two tumblers. In the illustrated embodiment, the more heavily loaded tumbler 31 is pushed in the direction of the stator 41, whereby an obstruction 44 is formed. At the same time, the less heavily loaded tumbler 32 is pushed in the direction of the stator 41, wherein the tumbler 32 is designed so that even in this situation, the associated Gegenzuhaltung 39 still protrudes into the rotor 36, i. the obstruction caused by the counter-lock 44 of the weaker loaded Zuhaltungs Gegenzuhaltungspaares remains even in the case of a given by the key opening 47 maximum, but not the keyhole engages behind filling the key channel. As a result, no conventional key without a moving element can solve the obstruction caused by the less loaded tumbler counteracting pair because it would require an elevation coding which would prevent such a key from being inserted into the locking cylinder ,
    5-7, the two tumbler Gegenzuhaltungspaare not perpendicular to the keyway 42 and they are not facing each other with respect to their reference axes. These are not mandatory requirements for the functionality of a key according to the invention in combination with a locking cylinder according to the invention. One or both tumbler Gegenzuhaltungspaare can also be arranged perpendicular to the key channel. Further, they may be collinear with each other with respect to their axes of motion, and they need not necessarily be normal to the key channel.
    Fig. 8 shows very schematically an alternative cross-sectional shape of a movable element 5. In contrast to the embodiment described above, the element has only three guide parts 8, which are also distributed asymmetrically.
    9 shows an embodiment which differs in the following features from that of FIGS. 1-8:The element has five guide parts 8. Alternatively, a different number of guide parts 8 is possible, for example, six, seven or eight, wherein the number is preferably at least three.The guide parts 8 have no constant width in function of the radial position, but taper towards the outside.
    These two features are independent of each other, i. Both elements with an arbitrary number of guide sections of constant width and elements with guide sections of non-constant width with, for example, an arrangement as in FIGS. 1-9 are conceivable.
    Guide sections of non-constant width may also include, for example, rounded or partially outwardly flared shapes.
