Description

The invention relates to a locking system. The field of application of the invention is directed to closing devices of motor vehicles, which according to the invention form a locking system comprising a plurality of locking devices.

From the DE 199 44 070 C2 a closure device with a key made for the closing device is known, wherein the key has surface sides and narrow sides on which code tracks on both surface sides of the key are arranged rotationally symmetrical to the longitudinal axis of the key. On each of the two surface sides, a profile typifying the key is attached in each case in the region of an edge. These profiles on both surface sides of the key are also arranged rotationally symmetrical to each other. Due to the rotationally symmetrical arrangement of the code tracks and the profiles of the key can be inserted in both possible insertion positions in the keyway of a lock cylinder. In this case, the key typifying profile is embedded in at least one of the narrow sides in the form of a three-sided closed groove in the key, and the groove is closed to the surface sides of the key.

The DE 10 2005 042 617 A describes a locking device, also consisting of a lock cylinder and a key. The locking cylinder includes a rotatably mounted in a cylinder housing cylinder core, which has tumblers. The coding of the key is generated by a profiled recess extending in the key longitudinal direction. The individual tumblers have sampling points which generate a counter coding corresponding to the key coding. In order to ensure a higher resistance to breakage of the closing device, it is proposed to provide a new beveled coding in the corner strips of the edge profile of the key. This consists of slanted sections of different depths. A portion of the beveled coding is associated with an oblique scanning point in at least one tumbler. This tumbler then acts as a beveled tumbler, which in addition to the tumblers of the standard design added. This can increase the variety of variations of the key.

From the DE 10 2005 042 618 A is a locking device removable, in which there are in the longitudinal direction of the key extending profiled recesses, which generate for each tumbler a pair of sampling points for encoding the key. Accordingly, each tumbler has a pair of counter-scans that have a corresponding counter-coding. For improved coding, it is proposed to arrange the one of the two scanning points on the one side surface of the key, while the other is located on the adjacent side surface. This pair of scanning points is generated by an angular recess in the two side surfaces, between which then a web remains in the corner of the edge profile of the key. Opposite web flanks are then used to code the key, which is why the web is to be regarded as a code web. The tumblers have a cutout which engages in the case of use, the code bar on opposite web edges. The cut-out boundary then serves as a counter-scanning point of the respective tumbler.

Finally, that is DE 10 2007 014 900 A1 known. The locking device also includes a key and a lock cylinder. The lock cylinder is in turn composed of a stationary cylinder housing and a rotatably mounted therein cylinder core. In order to increase the risk of breakage, it is proposed to use two types of plate tumblers in the cylinder core, whose displacements point in two mutually different radial directions. The key has at an angle to each other arranged flat outer surfaces to which the two types of platelet tumblers are displaced parallel. Each of the two adjacent outer surfaces has its own linear control track which varies to encode the key in adjacent key sections transverse to the key longitudinal direction. Correspondingly, the plate tumblers have a pair of counter-scanning points arranged in a defined position, which interact with the associated control track when the key is inserted and produce countercoding in the lock cylinder analogous thereto. Each of the two types of plate tumblers attacks on its own control track.

Due to the increased use of electronic access systems, the mechanical locking systems will be increasingly used in redundancy in the future. However, this means an increase in the requirements for the theft protection of the mechanical components, since the classic attack always hits the mechanics first, when there is no electronic way to overcome it.

The object of the invention is to develop a variable locking system, which is characterized by a high degree of variability of possible locking devices belonging to a closing device, each locking device should be variable in itself be formed to provide a high security against breakage.

At least two locking devices and a key belong to a locking system according to the invention, wherein the at least two locking devices are actuated with this key, wherein the key in the insertion direction axially in a keyway of a cylinder core of a lock cylinder of the respective locking device can be inserted, whereby at least two types of arranged in the cylinder core Platelet tumblers radially displaceable to the axial cylinder axis and are sorted in the cylinder core, that the cylinder core is freely rotatable relative to a cylinder housing of the lock cylinder, to which the key has at least two control tracks, by means of which in at least two successive each lying transversely to the insertion direction scanning planes scanning possible on the key provided sampling possible list.

To increase the security against breakage and to increase the variability, according to the invention, it is provided that both types of wafer tumblers can be scanned and sorted by means of a key in at least one of the at least two scanning planes, so that the arrangement of one type of the two platelet tumblers in at least one of these Scanning level is freely selectable to form a variety of locking devices with adapted to the free selection of the platelet tumblers cylinder cores with associated cylinder housings, which are each operable with the key.

State of the art:

The Figures 1A and 1B show a locking device 1 according to the prior art. A key bit of a key 2 is formed of a cantilever with mutually angled outer surfaces 2B, 2S. The key bit of the key 2 has a wide and a narrow outer surface 2B, 2S on. On the wide outer surface 2B, a Kodierbahn 8 as a first control track, in the form of a cam, arranged.

Hereinafter, when explaining the prior art and the explanation of the invention with the wording "key" always the key bit meant.

As Figure 1A shows, the locking device 1 has a cylinder core 4, which is rotatably arranged in a cylinder housing 3, not shown. In the cylinder core 4 platelet tumblers 5 are provided in recesses arranged for it. In Figure 1A are arranged platelet tumblers type 5A, whose form will be discussed in detail later.

This platelet tumblers 5A move relative to the axial cylinder axis 7 of the cylinder core 4 spring loaded by an arranged spring element 3A in the radial direction, according to FIG. 1 by way of example in a first radial direction of movement 7.1. The spring element 3A engages a projection 5-1 of the plate tumblers 5A.

In successive arranged in the direction of the cylinder axis 7, transverse to the cylinder axis scanning planes a plurality of such spring-loaded plate tumblers 5 of type 5A are arranged.

When inserting the key 2 into the cylinder core 4 in a direction of insertion E, the key 2 sorts the plate tumblers 5A against a spring force of spring elements, not shown, such that the platelet tumblers 5A in the cylinder housing 3 or in a freewheel sleeve 4A in the cylinder housing 3 arranged Sperrausnehmungen or locking channels of the cylinder housing 3 are led out, so that the cylinder core 4 or the cylinder core 4 in the freewheel sleeve 4A against the cylinder housing 3 is rotatable, whereby the locking device 1 is actuated. The coding, that is to say the sorting of the platelet tumblers 5A, takes place in the prior art via the control groove 8, which in FIG FIG. 1B is arranged on the broad side 2B of the key 2.

Is on the opposite side of the broad key side 2B also a control groove 8, arranged in mirror image, so the key is according to the prior art of FIG. 1A, 1 B is a reversible key, in accordance with Figure 1A with its narrow side 2S reciprocally inserted into the cylinder core 4, so that always one of the two on the broad side 2B opposite cam 8 takes over the coding, each with the same effect is achieved.

Regardless of which of the narrow sides 2S, according to Figure 1A is in the first radial direction of movement 7.1, it is thus ensured that one of the two control grooves 8 sorted the platelet tumblers 5 type 5A and the locking device 1 can be actuated. In this case, the cam groove 8 is designed such that the cam groove 8 per wafer tumbler 5A provides exactly one scanning point along the cylinder axis 7 for each one Gegenabtaststelle the wafer tumbler 5A.

In FIGS. 2A, 2B a further developed solution according to the prior art is shown. The key 2 is also formed as a rectangular profile, and each has a narrow side 2S and one wide side 2B. The cylinder core 4 has cutouts which are displaceable in the radial direction in a first and second radial movement direction 7.1, 7.2 relative to the cylinder axis 7. The plate tumblers 5 of the first type 5A are displaceable in the first radial direction of movement 7.1. The platelet tumblers 5 of the second type 5B are offset in the exemplary embodiment by 90 ° in a second radial direction of movement 7.2. The form of the plate tumblers 5A, 5B will be discussed in more detail in connection with the invention.

As FIG. 2B clarifies the platelet tumblers 5A analogous to Figure 1A, 1B in the radial direction of movement 7.1 via a first control track 8, moved in the manner of a control groove, wherein the cam 8 is also here on the broad side 2B of the key 2.

The second-type plate tumblers 5B are displaced by a second control track 9, in the manner of a control rib, this control rib 9 being arranged on the narrow side 2S of the key 2.

Will the key 2 in the in FIG. 2A shown cylinder core 4 inserted in the direction of insertion E, so on the one hand the cam 8 and on the other hand, the control rib 9 ensures that the platelet tumblers 5A, 5B also here against the force of an associated spring element (not shown) within the cylinder core 4 or within a freewheel sleeve 4A in the cylinder core 4 are displaced, so that the platelet tumblers 5A, 5B from not shown Sperrausnehmungen or Sperrkanälen, the cylinder core 4 surrounding cylinder housing 3 or arranged in the cylinder housing 3 freewheel sleeve 4A are moved out, whereby the cylinder core 4 with respect to the Cylinder housing 3 is rotatable and the locking device 1 by turning the cylinder core 3 relative to the cylinder housing 3 is actuated.

In this case, the control tracks 8, 9, that is, the control groove and the control rib, configured such that seen in the direction of the cylinder axis 7, lying in the insertion direction E transverse to the cylinder axis 7 imaginary planes in the control groove 8 and on the control rib. 9 exactly one scanning point of the key 2 is provided in each plane for only one type of the plate tumblers 5A or 5B. In each scanning plane, only one scanning point on the key, which corresponds to a counter-scanning point on the wafer tumbler 5A or 5B, is formed. The shape of the control groove 8 and the control rib 9 determines from the outset which type of wafer tumbler 5A or 5B in the respective scanning plane can be scanned by exactly one scanning point present in the scanning plane. This arrangement limits the variability of the arrangement of the platelet tumblers in the respective scanning plane and limits the security against break-ins.

In the first scanning plane, the control groove 8 scans the first wafer tumbler 5A. The control rib 9 has no function in the second scanning plane. In the second scanning plane, the control rib 9 scans the first second-type pad guard 5B. Here then the cam 8 has no function. In each scanning plane, only one scanning point is provided on the key 2 for one type of die tumblers 5A or 5B, which again makes it clear that the coding or sorting possibilities are based on the number of die tumblers 5A, 5B according to the number of platelets Scanning levels are limited.

Is on the opposite side of the wide key side 2B also a control groove 8 and on the opposite side of the narrow key side 2C also a control rib 9, the key axis arranged in mirror image, so the key is according to the prior art of FIGS. 2A, 2B a reversible key, in accordance with FIGS. 2A, 2B with its narrow or wide side 2S, 2B mutually insertable into the cylinder core 4, so that always one of the two opposite control grooves 8 and control ribs 9 takes over the coding, the same effect is achieved.

Regardless of which of the opposite narrow sides 2S according to FIG. 2A is in radial displacement direction 7.1, it is thus ensured that one of the two control grooves 8, the platelet tumblers 5A and one of the two control ribs 9, the platelet tumblers 5B sorted, whereby the locking device 1 can be actuated.

FIG. 3 shows a closing device 1 according to Figure 1A, 1B or FIGS. 2A, 2B in a sectional view. In the cylinder housing 3 is the rotatable cylinder core 4 in the embodiment inside a free-wheeling sleeve 4A, wherein the locking device 1 has been cut in the plane in which a plate tumbler 5 of type 5A lies. Locking devices without freewheeling sleeve 4A are also previously known.

The small plate tumbler of the first type 5A is displaceable in a first radial direction of movement 7.1 by the key 2, which can be plugged into the key channel 6.

In FIG. 3 is the platelet tumbler of the first type 5A led out of the cylinder core 4, so that the locking device 1 is not closable, since the platelet tumbler 5A indirectly blocks the cylinder core 4 with respect to the cylinder housing 3 visible here. The indirect blocking takes place via the freewheel sleeve 4A, the function of which is known per se.

The following invention can be used for closing devices 1, regardless of whether a direct blocking without freewheel sleeve 4A or an indirect blocking - for example, on the in FIG. 3 shown freewheel sleeve 4A - takes place.

If the key 2 (not shown) inserted into the keyway 6, so the platelet tumbler 5A in the radial direction of movement 7.1 according to FIG. 2 moved down so that the cylinder core 4 can be rotated relative to the cylinder housing 3. The movement of the platelet tumbler 5A takes place against the force of the spring element shown schematically. 3A. The protrusion 5-1 presses against the spring member 3A respectively associated with each of the first-type platelet tumblers 5A. The same procedure is carried out at the wafer locking device 5 of the second type 5B, which is, however, moved in another radial direction of movement 7.2.

In the following description of the figures, the same reference numerals are always used for the same components.

The arrangement of a vehicle seat within a motor vehicle and its usual direction of travel determine the following directions. In or against the direction of travel corresponds to the x-direction, the vertical direction in a vehicle is set with the z-direction, the axes extending transversely to the direction of travel in the y-direction.

However, the description with x, y, z directional information are only exemplary and may change depending on the arrangement of a locking system in the motor vehicle and thus variable direction of the key channel of the locking devices of the respective locking system.

In order to be able to indicate direction of travel without directional changes, the axial direction of the cylinder axis 7 is defined, from which the first radial and second radial direction of movement 7.1, 7.2 for the plate tumblers 5A, 5B. 5C, 5D.

To the cartesian coordinates of FIGS. 1A to 3 , An insertion direction E of the key 2 can take place, for example, in the x direction. In this case, the keyway 6 is for example aligned so that in a motor vehicle, the broad side 2B in the vertical direction in the z-direction and the narrow side 2B of the key 2 in the y-direction. This means that the platelet tumblers 5 of the first type 5A in such a closure device 1 in the first radial direction of movement 7.1 in the z-direction and the platelet tumblers 5 of the type 5B in the second radial direction of movement 7.2 transversely to the direction of travel in y- Move direction. If the insertion direction E changes, the Cartesian coordinates also change accordingly.

Furthermore, a first sectional plane D _{x / z is} defined, which corresponds to the key 2 FIG. 2B along its broad outer sides 2B, 2B 'in the x / z plane. The control tracks 9, 10, 14 or 9 ', 10', 14 'on the narrow outer sides 2S, 2S' of the key are thus cut according to the following description of the invention mentally in half.

Analogously, a second sectional plane D _{x / y is} defined, which corresponds to the keys 2 and 8 ', respectively FIG. 2B along its narrow outer sides 2S, 2S 'in the x / y plane intersects. The control tracks 8 and 8 'on the broad outer sides 2B, 2B' of the key 2 are thus according to FIG. 2B mentally cut in half.

In the following five embodiments, the explanation is based on an insertion direction E in the x-direction.

The coherent concept of the invention lies in the fact that at least one locking system S _n (S ₁ , S ₂ , S ₃ , S ₄ , S ₅ ), which is described in more detail below in five embodiments, is provided to increase the security against breakage and to increase the variability that by means of a key 2 in at least one of at least two scan planes 11 _n both types of plate tumblers 5A, 5B or 5A, 5C, or 5C, 5D are scanned and sorted, so that the arrangement of one type of the two plate tumblers 5A, 5B or 5A, 5C or 5C, 5D in this at least one lying in the cylinder core 4 in the direction of insertion E of the key 2 in the cylinder core 4 lying scanning plane 11 _{n is} freely selectable.

It is not fixed from the outset therefore unlike the prior art, which type of plate tumblers 11 is arranged in such a scanning plane _n.

On the representation of the respective projection 5-1 on the platelet tumblers 5A, 5B, 5C, 5D on which in each case a spring element 3A is supported, is omitted in the following illustrations. At the end of the description, however, the importance of the spring element 3A which in FIG. 3 is shown in detail in the context of the present invention.

First embodiment:

First locking system S ₁ in a first embodiment according to Figure 4A, 4B ,

First, the wafer tumblers of the first and second type 5A, 5B are as shown in FIG FIG. 5C and FIG. 5D presented in the locking system S ₁ - but not only there - in the various embodiments of the first locking system S ₁ are used. As already described in the prior art, the plate tumblers 5A, 5B each have an opening into which the key 2 can be inserted. The platelet tumbler 5A after FIG. 5D has a tumbler nose 5A-1, which engages in the control groove 8 of the key 2. The plate tumbler 5B, according to FIG. 5C a tumbler groove 5B-1 into which the control rib 9 of the key 2 engages.

FIG. 4A shows the key 2 in a perspective view with its narrow side 2S and its broad side 2B. On the broad side 2B, the cam 8 is arranged. The cam groove 8 has a first groove flank 8A and a second groove flank 8B. The in the first radial movement direction 7.1 movable platelet tumbler 5A is pressed on the already described, but not shown here spring element with its Gegenabtaststelle in the direction of the first groove flank 8A to a provided on the key 2 sampling.

The opposite second groove flank 8B serves as a positive guide for the tumbler nose 5A-1 of a wafer tumbler 5A.

On the narrow side 2S of the key 2, the control rib 9 is arranged, which has a first rib flank 9A and a second rib flank 9B. The already described associated, However, spring element, not shown, presses the plate 5-tumbler 5 type with its counter-scanning to the sampling of the first rib edge 9A, the second rib edge 9B serves as a forced guide for the platelet tumbler.

Thus, the visible first groove flank 8A is the control groove of the first-type pad tumbler 5A and the invisible lower first rib flank 9A is the control flank of the second-type plate tumbler 5B.

Along the axis of rotation symmetrically located in the cylinder core 4 key axis 7 are located in different imaginary transversely to the key axis 7 levels 11 ₁ to 11 ₁₀ both sampling 12 ₁ to 12 ₁₀ on the first groove flank 8A and on the first rib flank 9A.

The peculiarity of the first locking system S ₁ in the first embodiment is that in the first scanning plane 11 ₁ only one scanning 12 _{1 is performed} on the first groove flank 8A for a wafer tumbler 5 of the first type 5A. In this first scanning plane 11 ₁ , only one of the two types of wafer tumblers 5A, 5B can be interrogated.

In the second scanning plane 11 ₂ , however, it is possible to interrogate both the first-type platelet tumbler 5 and the second-type platelet tumbler 5 5b via their counter-scanning positions.

"Queries" is understood as meaning the scanning and sorting of the counter-scanning points of a wafer tumbler by the scanning points of a key 2 within the closing device, in particular a locking cylinder.

For this purpose, the control rib 9 on the first rib flank 9A is a scanning point 12 ₂ for platelet-tumbler 5 of the second type 5B. At the same time on the first groove flank 8A in the second scanning plane 11 ₂ also a scanning 12 ₂ for a wafer tumbler 5 of the first type 5A executed. Thus, according to the invention, it is possible to interrogate both types of wafer tumblers 5A, 5B in the second scanning plane 11 ₂ . In a cylinder core 4, the user can freely choose whether to set the wafer tumbler 5 in the second scanning plane 11 ₂ , whether he / she has the first-type platelet tumbler 5 A or the second-type platelet tumbler 5 5B arranges.

In both cases, it is ensured when inserting the key 2 into the key channel 6 that in one and the same second scanning plane 11 _2, a query of the selected arranged platelet tumbler of the first type 5A or the second type 5B takes place.

This sequence of sampling points 12 _n in a scan plane 11 _n, wherein in a scanning plane 11 _{n is} not _a selection of the type of platelet-tumbler 5 and the next scanning plane 11, the selection of the type 5A or 5B _n platelet tumblers is composed, is in the in FIG. 4A Key 2 shown continued.

To illustrate the number of sampling points 12 _n that the key 2 offers in a scanning plane 11 _n , in the various scanning planes 11 ₁ to 11 are ₁₀ lines in a one-dot-and-dash sequence, that is to say possible scanning point 12 _n in a scanning plane 11 _n - or a two-point stroke sequence - that means two possible sampling points 12 _n in a scanning plane 11 "shown.

Whenever there is a one-dot-dash sequence, in this scan plane 11 _n only one scan point 12 ₂ is provided for either a first-type platelet tumbler 5A or a second 5B. If the line is represented by two dots and a dash (two-dot-dashed sequence), two scanning points 12 ₂ are provided in this scanning plane for an optional arrangement of a first type 5A or second type 5B plate tumbler 5. This type of presentation is used equally in all other figures.

Analogous to the second scanning plane 11 ₂ is thus in the eighth scanning 11 ₈ on the key 2 a sampling 12 ₈ both for the counter-scanning of the wafer tumbler 5A and for the counter-scanning of the wafer tumbler 5B at the associated first groove flank 8A and the first Rib edge 9A provided.

This design is also used in the FIG. 4B clarified. In FIG. 4B In the middle illustration, a plan view of the broad side 2B of the key 2 is shown. The respective first groove flank 8A of the control groove 8 has in each of the scanning planes 11 ₁ to 11 ₁₀ lying on the first groove flank 8A scanning 12 ₁ to 12 ₁₀ , which are marked for clarity with a small rectangle.

One of these sampling points, namely the Abtaststele 12 ₁₀ in the scanning plane 11 ₁₀ for the wafer tumbler 5A, is marked separately. Starting from the second scanning plane 11 ₂ is on the first rib edge 9A in the respective second scanning plane 11 ₄ , 11 ₆ , 11 ₈ and 11 _10th a sampling position 12 _2, 12 _4, 12 _6, 12 ₈ and 12 ₁₀ executed. Thus, in the respective scanning plane 11 ₂ , 11 ₄ , 11 ₆ , 11 ₈ and 11 ₁₀ freely selectable, which of the plate tumblers 5 type 5A or 5B to be positioned with their counter-scanning in this scanning plane.

This results in the significant advantage that the first locking system S _{1 can} consist of at least two key devices, which are characterized by differently arranged platelet tumblers 5A, 5B. However, the same key 2 can always be used for each locking device equipped differently with plate tumblers. For example, the same key 2 may be used as a key for a door closing cylinder for a first closing device and on the other hand as a key for a steering lock cylinder for a second closing device.

In this case, the first possibility is to form a closing device in which only platelet tumblers 5 of the type 5A are arranged, whose counter-scanning point are scanned via the scanning points 12 ₁ to 12 _{10 of} the first groove flank 8A of the first control track 8.

Furthermore, the second possibility is to form a closing device in which only wafer-type tumblers 5 of type 5B are arranged which, via their counter-scanning points at the scanning points 12 ₂ , 12 ₄ , 12 ₆ , 12 ₈ , 12 _{10 of} the first rib flank 9A of FIG second control track 9 are scanned.

Finally, the third possibility is to form a locking device in which both types of plate tumblers 5A, 5B are arranged, wherein in the scanning planes 11 ₂ , 11 ₄ , 11 ₆ , 11 ₈ , 11 _{10 is} variably selectable, which of the two Platypus tumblers 5 type 5A or type 5B are arranged, wherein in all possible embodiments, the same key 2 can be used for at least two locking devices to sort the platelet tumblers 5A, 5B via their counter-scanning so that the cylinder core 4 is rotatable relative to the cylinder housing 3.

Also, like the top and bottom views of the FIG. 4B illustrates, the key 2 of the first locking system S ₁ executable as a reversible key. As in FIG. 4A only partially visible, lies on the opposite side of the control rib 9 a mirror image of the second cutting plane D _{x / y} arranged control rib 9 A '.

Likewise lies - as in the FIGS. 4A and 4B not shown - on the opposite side of the key 2 of the first control track 8 a mirror image of the first sectional plane D _{x / z} arranged first control track 8 'with an opposite first groove flank 8 A'.

In the upper schematic illustration of FIG. 4B , is based on the middle representation of the FIG. 4B , the control rib 9 'lying on the narrow side 2S' of the key 2 'facing the narrow side 2S of the key 2.

At the bottom schematic illustration of FIG. 4B is based on the middle representation of the key 2 of the FIG. 4B the control rib 9 located at the top of the narrow side 2S.

An arrangement of (in FIG. 4A Visible, the opposite first control track 8 'is not visible) sampling 12 _n on a reversible key are in the schematic figures of FIG. 4B represented by the rectangles.

By this reversible key design, it does not matter how the key 2 is inserted into the space provided elongated keyway 6 in the insertion direction E. The described effects and advantages are always retained.

Upon insertion of the key 2 in a first position, the flanks 8A, 9A are used to scan the counter-scanning points of the first and second type of platelets 5, 5B (two-track locking system).

Upon insertion of the key 2 in a second position (reversible key position), the flanks 8A ', 9A' are used to scan the counter-scanning points of the first and second type of platelet tumblers 5, 5B (two-track locking system).

First embodiment:

First locking system S ₁ in a second embodiment according to 4C, 4D ,

The peculiarity of the first locking system S ₁ in the second embodiment, which is shown in_Figur 4C, 4D, consists in the fact that on the key 2 in the first scanning plane 11 ₁ two sampling 12 ₁ on the first groove flank 8A for a wafer tumbler 5 from Type 5A and on the first rib flank 9A for the plate tumbler 5 type 5B is executed. In this first scanning plane 11 ₁ thus both types of plate tumblers 5A, 5B be queried on their Gegenabtaststellen, with a type 5A or 5B must be selected.

In the second scanning level 11 _{2, there} is now only the possibility of interrogating the wafer tumbler 5 of the first type 5A. The control rib 9 has on the first rib flank 9A of the second scanning plane 11 ₂ no sampling 12 ₂ for the wafer tumbler type 5B. In a cylinder core 4, the user can freely choose whether to set the wafer tumbler 5 in the first scanning plane 11 ₁ , whether he / she has the first-type platelet tumbler 5 A or the second-type platelet tumbler 5 5B arranges. In both cases, when inserting the key 2 into the keyway 6, it is ensured that in one and the same first scanning plane 11 _{1 there is} a query of the counter-scanning point of the selected wafer tumbler 5A or 5B.

This sequence of sampling points 12 _n in a scan plane 11 _n, wherein in a scanning plane 11 _{n is} not _a selection of the type of platelet-tumbler 5 and the next scanning planes 11, the selection of the type 5A or 5B _n platelet tumblers is composed, is in the in FIG. 4C Key 2 shown continued. To illustrate the number of sampling points 12 _n in a scanning plane 11 _n , the one-dot-dash sequence or the two-dot-dash sequence is again used in the various scanning planes 11 ₁ to 11 ₁₀ with the aid of the illustrated lines.

Analogous to the first scanning plane 11 ₁ is thus, for example, in the seventh scanning plane 11 ₇ a sampling 12 ₇ both for the platelet tumbler 5 of the first type 5A and for the platelet tumbler 5 of the second type 5B at the associated first groove flank 8A and first rib flank 9A provided.

This design is also used in the Figure 4D clarified. In Figure 4D is shown in the middle schematic figure, a plan view of the key 2. The respective first groove flank 8A of the control groove 8 has in each of the scanning planes 11 ₁ to 11 ₁₀ lying on the first groove flank 8A scanning 12 ₁ to 12 ₁₀ , which are again marked for clarity with a small rectangle. One of these sampling points, namely the Abtaststele 12 ₉ in the ninth scanning level 11 ₉ for the wafer tumbler 5A, is marked separately.

Starting from the first scanning plane 11 ₁ , a scanning point 12 ₃ , 12 ₅ , 12 ₇ , and 12 _{9 is} executed on the first rib edge ₉ A in the respective second scanning plane 11 ₃ , 11 ₅ , 11 ₇ and 11 ₉ . Thus, in the respective scanning plane 11 ₃ , 11 ₅ , 11 ₇ , and 11 ₉ freely selectable, which of the platelet tumblers 5 of type 5A or 5B should be positioned in this scanning plane and queried via the respective counter-scanning point.

This also results here in the significant advantage that the first locking system S _{1 of} the second embodiment can consist of at least two key devices, which are characterized by differently arranged platinum tumblers 5 of the first and second type 5A, 5B. However, the same key 2 can be used for each of the closing devices provided in this way.

Here, too, the first possibility is to form a locking device in which only platelet tumblers of the type 5A are arranged, which are queried on the sampling 12 ₁ to 12 _{10 of} the first groove flank 8A of the first control track 8.

Furthermore, here also the second possibility is to form another locking device so that only platelet tumblers of the type 5B are arranged, which at the sampling 12 ₁ , 12 ₃ , 12 ₅ , 12 ₇ , 12 _{9 of} the first rib edge 9A of the second Control track 9 are scanned. See, for example, one of these sampling points 12 ₉ , 11 ₉ for a plate tumbler 5 type 5B of Figure 4D ,

Finally, the third possibility is to form a closing device in which both types of plate tumblers 5A, 5B are arranged, wherein in the scanning planes 11 ₁ , 11 ₃ , 11 ₅ , 11 ₇ , 11 _{9 is} variably selectable, which of the two Type 5A or type 5B slide tumblers are arranged, in all possible embodiments the same key 2 can always be used for at least two closing devices in order to sort the platelet tumblers 5A, 5B via their counter-scanning points in such a way that the cylinder core 4 is rotatable relative to the cylinder housing 3.

Also, like the top and bottom schematic illustration of the Figure 4D illustrates, the key 2 ', 2S / 2, 2S of the locking system S1 executable as a reversible key. As in FIG. 4C only partially visible, lies on the opposite key side 2 ', 2S' of the key 2, 2S of the control rib 9 a mirror image of the second Schnittitteberie D _{x / y} arranged control rib 9A '.

Likewise lies - as in the Figures 4C and 4D not shown - on the opposite side of the key 2, 2B of the first control track 8 a mirror image of the first sectional plane D _{x / z} arranged first control track 8 'on the side 2', 2B 'with an opposite first groove flank 8 A'.

In the upper schematic illustration of Figure 4D is based on the middle figure of the FIG. 4C the bottom of the narrow side 2S 'lying control rib 9' shown.

In the lower picture of the Figure 4D is based on the middle figure of the FIG. 4B the control rib 9 located at the top of the narrow side 2S.

The possible visible sampling points 12 _{n of} a reversible key are shown in FIGS Figure 4D again represented by the rectangles.

Through this reversible key execution it also does not matter how the key 2 is inserted into the elongated keyway 6 provided in the insertion direction E. The described effects and advantages are thereby always maintained.

Upon insertion of the key 2 in a first position, the flanks 8A, 9A are used to scan the counter-scanning points of the first and second type of platelets 5, 5B (two-track locking system).

Upon insertion of the key 2 in a second position (reversible key position), the flanks 8A ', 9A' are used to scan the counter-scanning points of the first and second type of platelet tumblers 5, 5B (two-track locking system).

First embodiment:

First locking system S ₁ in a third embodiment according to FIGS. 4E, 4F ,

The locking system S ₁ according to FIGS. 4E and 4F corresponds to the second embodiment according to 4C, 4D , while the first control groove 8 on the opposite broad side 2B 'of the key 2 with respect to the first sectional plane D _{x / z arranged} mirror-inverted to the first control groove 8', but the control ribs 9, 9 ', as the upper and lower illustration of the FIG. 4F illustrates, compared to the second sectional plane D _{x / y} not mirror image executed.

This results in the formation of the first locking system S ₁ according to the third embodiment, the first way to form a locking device, in which only platelet tumblers of type 5A are arranged on the sampling 12 ₁ to 12 _{10 of} the first Nut flank 8A or the first mirror-inverted arranged first groove flank 8A 'of the first control track 8, 8' are queried. Then the key 2 can be used as before as a reversible key.

Furthermore, here also the second possibility is to form a closing device in which only plate tumblers of the type 5B are arranged, which at the sampling points 12 ₁ , 12 ₃ , 12 ₅ , 12 ₇ , 12 _{9 of} the first rib flank _{9 A} of the second control path 9 or the non-mirror image arranged rib edge 9A 'of the second control path 9' are queried about their counter-scanning. The key 2 can then no longer be used as a reversible key, since the control ribs 9, 9 'are not arranged in mirror image.

Finally, the third possibility is to form a closure device in which both types of die tumblers 5A, 5B are arranged, wherein the die tumblers 5A, 5B are variably selectable in all the scan planes 11 ₁ to 11 ₁₀ because the die tumblers 5B of the type 5B are mutually arrangeable such that the plate tumblers 5 type 5B with its counter-scanning in a closing device of the second system S2 once in the scanning planes 11 ₂ , 11 ₄ , 11 ₆ , 11 ₈ , 11 ₁₀ in the sampling 12th ₂ , 12 ₄ , 12 ₆ , 12 ₈ , 12 ₁₀ over the first rib edge 9A or in the scanning planes 11 ₁ , 11 ₃ , 11 ₅ , 11 ₇ , 11 ₉ in the sampling 12 ₁ , 12 ₃ , 12 ₅ , 12 ₇ , 12 ₉ of another closing device belonging to the second locking system S2 can be scanned over its counter scanning position on the first rib edge 9A ', which is not arranged in a mirror image.

It will be understood that the second type plate tumblers 5B need to be offset by 180 ° in every other scanning plane 11 ₁ to 11 ₁₀ , so that the tumbler groove 5B-1 once scans the counter-scanning positions of the second type platelet tumblers 5B via the first rib flank 9A in the scanning planes 11 ₁ : 11 ₃ , 11 ₅ , 11 ₇ , 11 ₉ with the scanning points 12 ₁ , 12 ₃ , 12 ₅ , 12 ₇ , 12 ₉ and another time the counter-scanning points of the platelet tumbler 5 of the second type 5B via the first opposing rib flank 9A 'in the scan planes 11 ₂ , 11 ₄ , 11 ₆ , 11 ₈ , 11 ₁₀ in the scan locations 12 ₂ , 12 ₄ , 12 ₆ , 12 ₈ , 12 ₁₀ .

In all possible embodiments, the same key 2 can always be used for at least two closing devices in order to sort the first-type and second-type slide tumblers 5B via the counter-scanning points such that the cylinder core 4 is rotatable relative to the cylinder housing 3. The key 2 can not be used as a reversible key, since the control ribs 9, 9 'are not arranged in mirror image.

When the key 2 is inserted, the flanks 8A, 9A, 9A 'are used in a first position for scanning the counter-scanning positions of the first or second type of platelet tumblers 5 (FIGS. 5A, 5B) (three-track locking system).

An insertion of the key 2 in a second position (reversible key position) is not possible by the non-mirror image arrangement of the control ribs 9, 9 '.

Second embodiment:

Second locking system S ₂ according to the FIGS. 5A to 5G in a first embodiment.

The FIGS. 5A to 5J show a second locking system S ₂ in a first embodiment.

The second locking system S ₂ is characterized in that in each of the scanning planes 11 _{n is provided in} each case a scanning point 12 _n for the counter-scanning of the platelet tumbler 5 of the first type 5A and for the counter-scanning of the platelet tumbler 5 of the second type 5B.

The FIGS. 5C and 5D show the two platelet tumblers 5 from the first and second 5A and 5B, which have already been described in connection with the first locking system S ₁ .

The FIGS. 5A and 5B each show in perspective a key 2, wherein FIG. 5A the front side, the narrow key side 2S and the upper side shows the broad key side 2B. In FIG. 5B is the key 2 opposite FIG. 5A rotated by 90 ° down so that the first control track 8, the according to FIG. 5A pointing upwards, now facing the viewer, so that the rear narrow opposite side 2S 'is now shown above.

This will make the in FIG. 5A on the rear side control rib 9 'in FIG. 5 on the narrow top of the key 2 ', as a narrow outer surface 2S' visible.

As a result of the two-dot dashed line used in both figures, it becomes clear that a scanning point 12 _{n is} executed on each of the first groove flank 8 A and the first flank flank 9 A per scanning plane 11 _n . The opposite flanks, the second groove flank 8B and the second flank flank 9B, in each case form the forced guidance for the tumbler nose 5A-1 platelet tumblers 5A and 5B-1 of tumbler tumblers 5B, respectively.

By way of example, it is shown that in the first scanning plane 11 ₁ , a scanning point 12 ₁ for the counter scanning point of the first-type platelet tumbler 5A as well as the second type 5B can be scanned or scanned over the first groove flank 8A or the first flank flank 9A. By way of example, it is also shown in the fourth scanning plane 11 ₄ that both types of wafer tumblers 5A and 5B can be interrogated via the correspondingly executed control paths 8, 9.

This in turn results in the significant advantage that the second locking system S _{2 may} consist of at least two key devices, which are characterized by differently arranged platelet tumblers 5 both types 5A, 5B. For each of the thus formed or equipped with plate tumblers closing devices of the same key 2 can be used. In this case exists when in each of the imaginary scanning planes 11 _n both types of plate tumblers 5A, 5B are alternatively be arranged, also here a go beyond the prior art plurality of variable possibilities of the arrangement of platelet tumblers. The security against break-ins is thereby increased.

If the respective control track 8, 9 shown in the opposite control tracks 8 ', 9' mirror images of the first and second sectional plane D _{x / z} , D _{x / y} , always creates a reversible key, so that the key 2 in at least two locking devices in a first position and in a second position can be used as a reversible key.

Upon insertion of the key 2 in a first position, the flanks 8A, 9A are used to scan the counter-scanning points of the first and second type of platelets 5, 5B (two-track locking system).

Upon insertion of the key 2 in a second position (reversible key position), to scan the counter-scanning points of the first and second type of slide locks 5, 5B, the (in Figure 5A, 5B not shown) flanks 8A ', 9A' used (two-track locking system).

FIG. 5E shows for the second locking device, the first three scanning planes 11 ₁ , 11 ₂ , 11 ₃ and illustrates the arranged in the first and second control track 8, 9 in a scanning plane 11 ₁ , 11 ₂ , 11 ₃ possible sampling 12 ₁ , 12 ₂ , 12 ₃ .

In FIG. 5F is shown in the radial direction of movement 7.2 displaceable second platelet tumbler 5B shown, which forms a sampling 12 ₁ in the first scanning plane 11 ₁ on the first rib flank 9A of the second control path 9. The first rib flank 9A and the positive leading second rib flank 9B engage in the tumbler groove 5B-1 and control the second-type platelet tumbler 5B via its counter-scanning point in the radial direction of movement 7.2, which in the exemplary embodiment can lie in a y-direction according to the directional definitions.

The FIG. 5G shows analogous to the platelet tumbler of the first type 5A, which is sorted or scanned in the first radial movement direction 7.1 by the first cam groove 8 via the first groove flank 8A and the positively driven second groove flank 8B by the insertion of the key 2. This results in how one compares to FIG. 5F detects the optional arrangement of a scanning point 12 ₁ in the first scanning plane 11 ₁ for the counter-scanning point of a wafer-holding device 5 of the first type 5A, instead of the second type 5B ( FIG. 5F ).

If the radial direction of movement of the platelet tumbler 5 is of the second type 5B in the direction of movement 7.2, for example in a vehicle in the y direction, then the direction of movement of the platelet tumbler 5 of the first type 5A is orthogonal thereto in the z direction, for example according to the direction of movement 7.1 arranged.

If a key 2 is introduced, for example, in the vehicle direction x into a key channel and the narrow side 2S of the key 2 lies horizontally in the y direction in a vehicle, then the plate tumbler 5 of the type 5B is displaced horizontally in the y direction according to the direction of movement 7.2 and the plate tumbler 5 type 5A in the vertical direction in the z direction in the direction of movement 7.1 moved.

Second embodiment:

Second locking system S ₂ according to the Figures 5H to 5J in a second embodiment.

According to the FIGS. 5H, 5I, 5J However, it is also possible, the second locking system S _{2 in} such a way that the second control track 9 and the opposite control track 9 'on the narrow outer sides 2S, 2S' of the key 2 with respect to the second sectional plane D _{x / y are} not formed mirror images.

This second embodiment of the second locking system is in the FIGS. 5H, 5I, 5J clarified.

This in turn results in the following possibilities to form the closing devices.

In order to follow the inventive idea and within the second locking system S _2, the second locking system S ₂ in the second embodiment is characterized also by the fact that in at least one, here in each of the scanning planes 11 _n each having a scanning point 12 _n for a platelet Guard lock 5 of the first type 5A and is provided for a platelet lock 5 of the second type 5B, but not always a reversible key can be produced by the non-mirror image arrangement of the control rib 9, 9 ', as will be explained below.

In FIG. 5I In the schematic illustration, only one of the control ribs 9 on the narrow outer side 2S of the key 2 is shown. In the presentation of FIG. 5I is based on the FIG. 5H shown on the narrow side 2S of the key 2 control rib 9.

The opposite control rib 9 'is compared to the second sectional plane D _{x / y,} as FIG. 5J shows, not arranged in mirror image.

On the one hand, via the first control groove 8A of the first control track 8 and the first control rib 9A of the second control track 9 in each of the scanning planes 11 ₁ , 11 ₂ , 11 ₃ , 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ a sampling 12 ₁ , 12th ₂ , 12 ₃ , 12 ₄ , 12 ₅ , 12 ₆ , 12 _{7 can be} formed.

On the other hand, via the first opposing cam groove 8A 'of the first control track 8' and the first control rib 9A 'of the second opposing control track 9' in each of the scanning planes 11 ₁ , 11 ₂ , 11 ₃ , 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ a sampling 12 ₁ , 12 ₂ , 12 ₃ , 12 ₄ , 12 ₅ , 14 ₆ , 12 _{7 can be} formed.

If in a possibility in a closing device only platelet tumblers of the first type 5A arranged, they will each have the sampling points 12 ₁ to 12 _{7 of} the first groove flank 8A or 8A ', the first control track 8 or the opposite first control track eighth , 'which are arranged in mirror image, queried. This creates a locking system S ₂ for several such closing devices, in which the key 2 is still designed as a reversible key.

There is also the second possibility of disposing only second-type die tumblers 5B in each of the successive scan planes 11 ₁ , 11 ₂ , 11 ₃ , 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ , either at the sampling points 12 ₁ , 12 ₂ , 12 ₃ , 12 ₄ , 12 ₅ , 12 ₆ , 12 _{7 of} the first rib edge 9A of the second control track 9 or for a further closing device only platelet tumblers of the second type 5B in each of the successive scanning planes 11 ₁ , 11 ₂ , 11 ₃ , 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ are arranged, which at the sampling 12 ₁ , 12 ₂ , 12 ₃ , 12 ₄ , 12 ₅ , 12 ₆ , 12 _{7 of} the non-mirror image arranged rib edge 9A 'of the second control track 9' are scanned. The key 2 can then no longer be used as a reversible key, since the control ribs 9, 9 'with respect to the second sectional plane D _{x / y are} not arranged in mirror image.

Starting from the above-described second possibility, an alternative embodiment is to arrange the plate tumblers 5 of the second type 5B that the platelet tumblers 5 of the second type 5B with their cooperating scanning in a closing device of the second system S ₂ once in a Scanning plane 11 _n on the first rib edge 9A and in a same scanning plane 11 _n of another to the second locking system S ₂ associated closure device is scanned over its counter-scanning by the non-mirror image arranged first rib edge 9A '. This is made possible by the effective direction of the spring element which presses the plate tumblers 5 in one or the other direction of the radial direction of movement 7.2. This key 2 can not be used as a reversible key.

Finally, the third possibility is to form a closing device in which both types of plate tumblers 5A, 5B are arranged, since the first and second type plate tumblers 5 are 5A, 5B in the consecutive scanning planes 11 ₁ , 11 ₂ , 11 ₃ , 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ variably selectable at the sampling 12 ₁ , 12 ₂ , 12 ₃ , 12 ₄ , 12 ₅ , 12 ₆ , 12 ₇ are arranged, wherein the same key 2 for at least two closing devices can be used to sort the platelet tumblers 5A, 5B via their counter-scanning points so that the cylinder core 4 is rotatable relative to the cylinder housing 3. The key 2 can then no longer be used as a reversible key, since the control ribs 9, 9 'of the second are not arranged in mirror image.

Upon insertion of the key 2 in a first position, the flanks 8A, 9A are used to scan the counter-scanning points of the first and second type of platelets 5, 5B (two-track locking system).

An insertion of the key 2 in a second position (reversible key position) is not possible by the non-mirror image arrangement of the control ribs 9, 9 '.

The scanning lines 12 ₁ , 12 ₅ in the scanning planes 11 ₁ , 11 ₅ are marked separately, the two-dot-dash sequence again indicating that in each scanning plane 11 _n, depending on the selection of the two types 5A, 5B of platelets. Tumblers 5 can be interrogated via their counter-scanning points.

Third and fourth embodiment:

Third and fourth locking system S3, S4 according to FIGS. 6A to 6E ,

The basic structure of the key 2 for the third and fourth locking system S ₃ , S ₄ is changed, since now a differently designed and arranged third control track 10 replaces the second control track 9.

For the third and fourth embodiments, movable platelet tumblers 5 of a third type 5C are thereby arranged in the second radial movement direction 7.2. This third type 5C is according to FIG. 6C as Gegenabtaststellen opposite tumbler stages 5C-1.

The first type 5A platelet tumbler 5 is as FIG. 6B shows, in the third and fourth embodiment of the locking system S ₃ , S _{4 used} unchanged.

The FIG. 6A shows the difference of these locking systems S ₃ , S ₄ to the two locking systems S ₁ , S _{2 of} the first and second embodiments.

The key 2 of the third and fourth locking system S ₃ , S ₄ has a third control track 10, whose control edge 10A on the narrow side 2S of the key 2 and their forced operation by a third on the key 2 now on the opposite narrow key side 2S ' as a control track 10 'in the form of a positive leading control edge 10A' (in FIG. 6A not visible) is formed.

This inevitably results in the modified form of the plate lock 5 of the third type 5C, which in FIG. 6A is drawn according to its intended position relative to the key 2, wherein the support of one of the two tumbler levels 5C-1 on the positive-leading control edge 10A 'is not visible.

Third embodiment:

Third locking system S ₃ according to FIGS. 6A, 6B, 6C in a first embodiment.

Analogous to the first locking system S ₁ , the third locking system S _{3 is characterized} in a first embodiment, which in the FIG. 6A is represented by the fact that in each second scanning plane 11 _n one sampling point 12 ₁ , 12 ₃ , 12 ₅ (starting with the first scanning plane 11 ₁ for a wafer tumbler 5 of the first type 5A and a wafer tumbler 5 from third type 5C is provided, whereby in these scanning planes 11 ₁ , 11 ₃ , 11 ₅ , a selection can be made, which type is arranged 5A or 5C.

The first scanning plane 11 _{1 of} the key 2 has, for example, the in FIG. 6A marked sampling point 12 ₁ for a Gegenabtaststelle for the plate tumbler 5 of the first type 5A and the third type 5C on.

However, the next scanning plane 11 ₂ then differs from the representation of FIG. 6A only one scanning point 12 ₂ on the plates for Locking the first type 5A.

This results in the advantage that the third locking system S _{3 of} the first embodiment can consist of at least two key devices, which are characterized by at least one scanning plane 11 _n variably arranged platelet tumblers of the first or third type 5A, 5C. For each of the correspondingly designed closing devices of the third locking system S ₃ , the same key 2 can always be used regardless of the arrangement of a plate tumbler 5 of the first or third type 5A, 5C.

In this case, there is the first possibility, a closing device in such a way that only platelet tumblers 5 of the first type 5A are arranged, the Gegenabtaststellen on the sampling 12 ₁ to 12 _n in each Abtstebenen11 ₁ to 11 _n on the first groove flank 8A of the first control path 8 queried.

Furthermore, the second possibility is to form a closing device in which only third-type plate tumblers 5C are arranged, the counter-scanning points of which are scanned at the scanning points 12 ₁ , 12 ₃ , 12 _{5 of} the control flank 10A of the third control path 10.

Finally, for a further closure device, the third option is to place both types of first and third type platelet tumblers 5, 5C, wherein in the scan planes 11 ₁ , 11 ₃ , 11 _{5 is} variably selectable, which of the two platelet tumblers 5 of the first type 5A or of the second type 5C are arranged and queried via the counter-scanning, wherein in all possible embodiments always the same key 2 for at least two closing devices may be used to sort the wafer tumblers 5A, 5C so that the cylinder core 4 is rotatable relative to the cylinder housing 3. *** "

Only the first control track 8 of the first embodiment of the third locking system S ₃ is mirror-inverted relative to the first sectional plane D _{x / z} , resulting in a key 2 with a first and third control track 8, 10, 10 'and a mirror image arranged opposite first control path 8 'results, which results in dependency of the selection of the plate tumblers 5A, 5C in the respective scanning plane 11 only _n a reversible key, when _n in the respective scanning plane 11 solely platelet tumblers 5 of the first type 5A are arranged.

Upon insertion of the key 2 in a first position, the flanks 8A, 10A are used to scan the counter-scanning points of the first and third type of plate tumblers 5, 5C (two-track locking system).

An insertion of the key 2 in a second position (reversible key position) is not possible by the non-mirror image arrangement of the control edges 10A, 10A 'of the third control track 10, 10'.

Third embodiment:

Third locking system S ₃ according to Figure 6D, 6E . 6F in a second embodiment.

The third locking system S ₃ is characterized in a second embodiment, which in the Figure 6D, 6E . 6F is represented by the fact that only one possible scanning point 12 _{7 is provided} for a variable arrangement of a wafer lock 5 of the first type 5A or for a wafer lock 5 of the third type 5C only in a single example, the seventh scan plane 11 ₇ .

The first to sixth scanning level 11 ₁ to 11 _{6 of} the key 2 has according to the FIGS. 6D, 6E . 6F as a special feature of this second embodiment, for example, a first to sixth sampling 12 ₁ to 12 ₆ for a Gegenabtaststelle, which are provided exclusively for the platelet tumblers 5 of the first type 5A.

The seventh to tenth scanning plane 11 ₇ to 11 ₁₀ has as a special feature of this second embodiment sampling points 12 ₇ to 12 ₁₀ , which are provided exclusively for the counter-scanning of the wafer tumblers 5 of the third type 5C.

In this case, the first control track 8 and the opposite control track 8 'from the outset only to the seventh scanning plane 11 ₇ executed and the third control track 10 and the opposite control track 10' is up to the scanning plane 11 ₆ simplified without contour and thus executed without coding function ,

The sampling points 12 ₁ to 12 _{10 of} the second embodiment variant of the third embodiment of a key 2 which are possible in the scanning planes 11 ₁ to 11 ₁₀ are again represented by the rectangles in the illustrations of FIG. 6F.

The upper schematic illustration of FIG. 6F shows the wide outer surface 2B of the key 2. Below the narrow outer surface 2S of the key 2 is shown schematically. Underneath, the opposite broad outer surface 2B 'is shown schematically. And at the bottom is the opposite narrow outer surface 2S 'shown.

As can be seen in the pictures of the FIG. 6F shown opposite broad outer sides 2B, 2B 'of the upper figure and the third figure can be seen from above, the first control track 8 and the opposite first control track 8' is executed in mirror image.

How to contact the in FIG. 6F shown opposing narrow outer sides 2S, 2S 'of the second figure from above and the fourth figure can be seen from above, the control edges 10A and 10A' are not mirror images.

Regardless of the described simplified design of the key 2, there is again the advantage that the third locking system S _{3 of} the second embodiment can consist of at least two key devices, which are characterized by differently arranged slide tumblers 5 of the first type 5A and the third type 5C ,

For each of the appropriately designed locking devices, the same key 2 can be used.

In this case, there is a first possibility of designing a closing device such that only platelet tumblers 5 of the first type 5A are arranged, whose counter-scanning points are scanned via the scanning points 12 ₁ to 12 _{7 of} the first groove flank 8A of the first control path 8. Furthermore, a second possibility is to form a closing device in which only third-type plate tumblers 5C are arranged, whose counter-scanning points are scanned at the scanning points 12 ₇ to 12 _{10 of} the control flank 10A of the third control path 10, 10A.

Finally, for a further closing device, the third possibility resides in arranging both types of plate tumblers 5A, 5C, wherein in this second variant of the third closing system S ₃ , the scanning plane 117 can be variably selected only in a single scanning plane, which of the two plates Of the first type 5A or of the third type 5C are arranged and interrogated via their respective counter-scanning point, wherein in all possible embodiments the same key 2 can always be used for at least two closing devices in order to sort the plate tumblers 5A, 5C, that the cylinder core 4 is rotatable relative to the cylinder housing 3.

Only the first control track 8 of the second embodiment of the third locking system S ₃ is arranged mirror-inverted on an opposite side of the key 2 with respect to the first sectional plane D _{x / z} , resulting in a key 2 with a first control track 8 and a mirror image arranged opposite first Control track 8 'results, which results in depending on the selection of the platelet tumblers 5A, 5C in the respective scanning plane 11 _n only a reversible key, if in the respective scanning plane 11 _n finally platelet tumblers 5 of the first type 5A are arranged ,

An example: For a vehicle with a keyless entry system or a keyless go system, a key bit is only needed to close the glove box and as an emergency key to unlock the driver's door in an emergency. For example, two locking devices with a key bit of the third locking system S _{3 of} the second embodiment variant are to be used.

For the glove box, for example, a lock cylinder 3, 3A, 4 or 3, 3A, 4 is used with a freewheel sleeve 4A, the platelet tumblers 5 are exclusively first platelet tumblers 5A, which scanned from the key bit in the scan planes 11 ₁ to 11 ₇ become.

It is understood that a higher or lower number of first-type platelet tumblers 5A can be arranged, since the number of seven platelet tumblers 5 is only exemplary. The key bit can, if in the lock cylinder only platelet tumblers 5 from are arranged as described without regard to the sides in the key channel 6 of the locking device 1 are inserted, since the key bit of the key 2 by the mirror image arrangement of the first control track 8 and the opposite first control track 8 'for the locking device. 1 the glove compartment as described is a reversible key.

For the emergency key on the driver's door but not necessarily a reversible key must be used, whereby the key 2 by the simplified design of the control tracks 8, 10 in particular the third control track 10 is cheaper to manufacture. For the lock cylinder 3, 3A, 4 or 3, 3A, 4, 4A of an emergency lock, there are exemplified slide hinges of the first type 5A and the third type 5C which scan the key blade in the scan planes 11 ₁ to 11 _10, for example. However, by using a third type 5C wafer holder 5, the key 2 is no longer usable as a reversible key since the third control path 10 and the opposite control path 10 'are not mirror images of the second cutting plane D _{x / y in the} exemplary embodiment are.

The third locking system S ₃ is like all other locking systems in the at least one scanning plane (here the scanning plane 11 ₇ ) of a designated sampling point (here the sampling 12 ₇ ) so variable that both types of wafer tumblers 5A and 5C scanned via their counter-scanning and are sortable, so that the arrangement of one type of the two plate tumblers 5A, 5C in at least one of these scanning plane 11 _{7 is} freely selectable, whereby the variability of the arrangement of platelet tumblers 5 of at least two locking devices (glove box closing device and emergency closing device on a driver's door or a boot) with cylinder cores adapted to the platelet tumblers 5A, 5C with associated cylinder housings.

In the scanning planes 11 ₁ to 11 ₆ is scanned, for example, on the first platelet tumblers 5A at the sampling points 12 ₁ to 12 _{6 of} the first groove flank 8A. Subsequently, in the scanning planes 11 ₇ to 11 _{10 are} scanned over the third platelet tumblers 5 C at the sampling points 12 ₇ to 12 _{10 of} the control edge 10A.

It should be understood that a higher or lower number of first type 5A or second type 5C die tumblers 5 may be arranged since the number of six first type 5A and four third type platelet tumblers 5C 5C is only an example.

However, the key bit can only be inserted into the keyway 6 of the locking device 1 so that the control edge 10, 10A pushes the plate tumblers of the third type in the scanning planes 11 ₇ to 11 ₁₀ at the sampling points 12 ₇ to 12 ₁₀ , whereby the cylinder core 4 is rotatable relative to the cylinder housing.

If the key 2 is inserted the other way round, the forced guideway 10A 'of the third control path 10', since it is not arranged mirror-inverted with respect to the second sectional plane D _{x / y,} does not push away the platelet tumblers 5C.

The presented key 2 of the third locking system S ₃ in the second embodiment forms by the formation of the opposite non-mirrored arranged control edges 10A, 10A 'of the third control track 10 and the opposite third control track 10', as mentioned above, with the platelet tumblers 5 of the third type 5C no reversible key.

This means that when inserting the key 2 in a first position for scanning the counter-scanning points of the first and third type of slide locks 5, 5C, the flanks 8A, 10A are used (two-track locking system).

An insertion of the key 2 in a second position (reversible key position) is not possible by the non-mirror image arrangement of the control edges 10A, 10A 'of the third control track 10, 10'.

Fourth embodiment:

Fourth locking system S ₄ according to Figures 6H and 6I ,

Analogous to the third locking system S ₃ , the fourth locking system S _{4 is} characterized in that according to FIG. 6H, 6I in each scanning plane 11 _{n of} the key 2 is provided in each case a scanning 12 ₁ , 12 ₂ , 12 ₃ for the counter-scanning of a wafer tumbler 5 of the first type 5A and for the counter-scanning of a wafer tumbler 5 of the third type 5C. In the other scanning planes 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ , 11 ₇ , 11 ₈ , 11 ₉ , 11 ₁₀ only platelet tumblers 5 type 5A can be arranged.

The first scanning plane 11 ₁ thus has an in FIGS. 6H and 6I marked sampling point 12 ₁ for the counter-scanning points of the plate tumbler 5 type 5A or platelet tumblers 5 type 5C on. The user can choose the arrangement of die tumblers 5A or 5C.

In the embodiment of FIGS. 6H and 6I In a special feature of this locking system S _4, only the first three scanning planes 11 ₁ , 11 ₂ , 11 _{3 are designed} for the two types of wafer tumblers 5 of the first type 5A and of the third type 5C. This embodiment can be extended to any number of further sampling points 12 _n in the scanning planes 11 ₄ , 11 ₅ , 11 ₆ , 11 ₇ , 11 ₇ , 11 ₈ , 11 ₉ , 11 ₁₀ . The variability of the arrangement of plate tumblers 5 type 5A or 5C increases accordingly.

The possible arrangement of the different types 5A or 5C of the plate tumblers 5 corresponds to the various embodiments, which has already been described for the third embodiment. A reversible key can, according to the logic of the third locking system S ₃ , be formed only if only platelet tumblers 5 of the type 5A are arranged, since the third control track 10 and the opposing third control track 10 'with respect to the second sectional plane D _{x / y is} not arranged in mirror image.

This means that when inserting the key 2 in a first position to scan the counter-scanning points of the first or third type of slide tumblers 5, 5C, the flanks 8A, 10A are used (two-track locking system).

An insertion of the key 2 in a second position (reversible key position) is not possible by the non-mirror image arrangement of the control edges 10A, 10A 'of the third control track 10, 10'.

Fifth embodiment:

Fifth locking system S ₅ according to FIGS. 7A to 7F ,

In the FIGS. 7A to 7F the difference of the fifth locking system S ₅ compared to the locking systems S ₁ , S ₂ , S ₃ , S ₄ described above is illustrated.

The key 2 of the fifth locking system S ₅ has the third control track 10 already used in the third and fourth locking systems S ₃ , S ₄ . Its control edge 10A is formed as before on the narrow side 2S of the key 2 and, as before, by the third force-guiding control edge 10A 'on the opposite narrow key side 2S' of the key 2 'of the opposite control path 10'.

However, unlike the previous locking systems S ₁ to S _{4, the} key 2 is provided with a fourth control track 14, 14 ', which is now arranged together with the third control track 10, 10'.

The used fourth control track 10 also has a control edge 14A on the fourth control track 14 of the broad side 2B of the key 2, wherein the forced guidance by a fourth on the key 2 now on the opposite wide key side 2B 'as a positive leading control edge 14A' of opposite lying fourth control track 14 'is formed.

This in turn inevitably results in a changed shape for the platelet tumblers 5 responsible for the fourth control path 14 or the opposite fourth control path 14 ', as will be explained below.

In the fifth locking system S ₅ are in the cylinder core 4, as FIG. 7A combined with FIGS. 2A, 2B and FIG. 3 shows, as previously arranged in the second radial direction of movement 7.2 movable platelet tumblers 5 of the third type 5C, which are queried by the third control path 10, 10 'of the key 2. This third type 5C of the plate tumblers 5 has according to FIG. 7A analogous to the FIG. 6C as Gegenabtaststellen to the sampling points of the key 2 on both sides arranged Zuhaltungsstufen 5C-1.

In the fifth locking system S ₅ are further in the cylinder core 4, such as FIG. 7B combined with FIGS. 2A, 2B and FIG. 3 shows, in the first radial movement direction 7.1 movable platelet tumblers 5 arranged: It is now platelet tumblers 5 of a fourth type 5D are queried by the fourth control path 14 or the opposite control path 14 'of the key 2.

This type 5D has analogous to FIG. 7A as Gegenabtaststellen also on both sides arranged tumbler stages 5D-1. This fourth type 5D of the plate tumblers 5 is thus designed to match the shape of the fourth control path 14, 14 'of the key 2.

The described design of the key 2 also results in this fifth locking system S ₅ having the advantage that the system S _{5 can} consist of at least two key devices, which are arranged in a scanning plane 11 _n different, variably selectable platelet tumblers 5, either of the third type 5C or the fourth type 5D distinguished. For each of the appropriately trained at least two locking devices, the same key 2 can be used.

There is a first possibility, like the FIGS. 7A to 7F by the two-dot chain sequence - illustrate, form a closing device, only platelet tumblers 5 are in all scanning planes 11 ₁ to 11 _{7 are} arranged from the third type 5C, the cooperating scanning over the scanning points 12 ₁ to 12 ₇ of the control edge 10A of the third control path 10 are queried.

Further, the second possibility is to form a closing device, in which only platelet tumblers 5 are arranged from the fourth type 5D in all scanning planes 11 ₁ to 11 _7, the cooperating scanning at the scanning 12 ₁ to 12 ₇ of the control flank 14A of the fourth control path 14 , 14A are scanned.

Finally, for a further locking device, the third possibility is to arrange both types of plate tumblers 5C, 5D, wherein in this fifth locking system S _{5 is} variably selectable in all scanning planes 11 ₁ to 11 ₇ , which of the two platelet tumblers of the third type 5C or of the fourth type 5D with their counter-scanning points which are interrogated by the scanning points 12 ₁ - 12 _{7 of} the key 2, wherein in all possible embodiments the same key 2 can always be used for at least two locking devices in order to lock the platelets 5 of the third type 5C and the fourth type 5D to sort so that the cylinder core 4 relative to the cylinder housing 3 is rotatable.

Some of the scanning points 12 ₁ , 12 ₃ , 12 ₄ , 12 ₆ in the scanning planes 11 ₁ , 11 ₃ , 11 _4, 11 ₆ are marked separately, wherein the respective two-point stroke sequence in these scanning planes 11 ₁ , 11 ₃ , 11 ₄ , 11 ₆ and also in the other scanning planes 11 ₂ , 12 ₅ , 12 ₇ indicates that the scanning points 12 ₁ , 12 ₃ , 12 ₄ , 12 _{6 of} the key in each scanning plane 11 _{n are} the counter-scanning points of a platelet tumbler 5 queries from the third type 5C or the fourth type 5D.

FIG. 7C shows the possible Abtastellen 12 ₁ in the scanning plane 11 ₁ . The two-dot-dash sequence in this scanning plane 11 ₁ indicates that in this embodiment, the counter scanning of the scanning 12 _{1 of} this scanning 11 _{1 of} the wafer tumblers 5 of the third type 5C or the fourth type 5D on the control edge 10A of third control path 10 or on the control edge 14A of the fourth control path 14 are queried.

In this case, the respectively opposite control edge 10A 'of the third opposing control track 10' and the opposite control edge 14A 'of the fourth opposing control track 14' again serves as forced guidance for that tumbler stage 5D-1 of the platelet tumblers of the third type 5C and the fourth Type 5D, which are not pressed by the spring element 3A not shown to the respective sampling point 12 _n .

Figure 7D refers, by way of example, to the possible scans 12 ₁ , 12 _{4 of} the key 2 in the scanning plane 11 ₁ and 11 ₄ . The two-point stroke sequence in the scan planes 11 _n points in the FIGS. 7A to 7F Again, in this embodiment, the counter-scanning points in these scanning planes 11 ₁ and 11 ₄ both types of wafer tumblers 5 of the third type 5C and the fourth type 5D on the control edge 10A of the third control path 10 or on the control edge 14A of the fourth control path 14 are queriable.

In Figure 7D however, the control edge 10, 10A of the third control track 10 is not visible, so that in Figure 7D by way of example only the scanning lines 12 ₁ and 12 ₄ in the scanning planes 11 ₁ and 11 _{4 are} indicated, which are queried via the counter-scanning points of the platelet tumblers 5 of the fourth type 5D.

In contrast, in the Figure 7E By way of example, reference is made only to the scans 12 ₃ and 12 ₆ in the scan planes 11 ₃ and 11 ₆ , which interrogate the counter-scan locations of the third-type die tumblers 5 5C.

In Figure 7E is the control edge 14A of the fourth control path 14, as it is not visible on the back of the key 2, so that the possible sampling of the control edge 14A of the fourth control path 14, which can query the counter-scanning of the wafer tumblers 5 of the fourth type 5D not can be marked with reference numerals.

The FIG. 7F again shows four schematic illustrations of the key 2 from top to bottom.

The scanning positions 11 ₁ to 11 ₇ possible scanning points 12 ₁ to 12 _{7 of} the key 2 of the fifth locking system S ₅ , which scan and sort the counter-scanning points of the plate tumblers 5 of the third or fourth type 5C, 5D are sorted in the figures FIG. 7F again represented by the rectangles.

It can be seen that the control edges 14A, 10A of the fourth and third control track 14, 10 in all exemplary illustrated Abtastebenen 11 ₁ to 11 _7, the possible variably usable sampling 12 ₁ to 12 _{7 of} the key 2 for the variably selectable platelet tumblers of the third or fourth type 5C, 5D.

The opposing control edges 14A 'and 10A' of the fourth and third opposing control tracks 14 ', 10' (upper illustration and illustration below) in this embodiment are the positive leading control edges 14A '10A' for the third or fourth type plate tumblers 5 5C, 5D.

The third schematic diagram from above shows the broad outer surface 2B of the key 2. Below this, the narrow outer surface 2S of the key 2 is shown schematically. At the top, the opposite broad key side 2B 'is shown schematically. Below this, at the second position, the opposite narrow key side 2S 'is shown.

How to contact the in FIG. 7F The control edge 14A 'of the fourth opposing control track 14' and the control edge 14A of the fourth control path 14 opposite the first sectional plane D _{x / are} shown opposite opposite broad outer sides 2B ', 2B, the upper illustration and the third illustration. _{z of} the key 2 is not mirror image executed.

How to contact the in FIG. 7F 2) shown further facing the second figure from above and the fourth figure from above, the control edge 10A 'of the third opposing control track 10' and the control edge 10A of the third control track 10 with respect to the second sectional plane D is shown _{x / y of} the key 2 also not mirror image executed.

The key 2 can thereby not be used as a reversible key, since the opposite control edges 10A, 10A 'of the third control track 10, 10' and the opposite control edges 14A, 14A 'of the fourth control track 14, 14' on the key 2 of the fifth Locking system S _{5 are} not arranged in mirror image.

This in turn means that upon insertion of the key 2 in a first position for scanning the counter-scanning positions of the third or fourth type die tumblers 5 5C, 5D, the flanks 10A, 14A are used (two-track locking system).

An insertion of the key 2 in a second position (reversible key position) is not possible by the non-mirror image arrangement of the control edges 10A ', 14A' of the third control track and fourth control track 10 ', 14'.

By the arrangement of different platelet tumblers 5A, 5B or 5A, 5C or 5C, 5D in the succession in the direction of insertion of the key 2 or the reversible key 2 scanning planes 11 _{n of} the closing devices of a locking system S _n , in particular a door lock cylinder or a steering starter cylinder or a Lock cylinder for a glove compartment, a number of different tools are required in a mechanically made break-in in one of the closing devices to move the platelet tumblers out of the locking recesses of the cylinder housing. The sequence of the arranged platelet tumblers of identical or different types of platelet tumblers in the direction of insertion can be selected such that the same types or different types of platelet tumblers are arranged in successive scanning planes.

The number of possible sequences of the platelet tumblers is increased over the prior art, in particular when different types of platelet tumblers are placed in a closure device, the variability of the arrangement and hence the multiplicity of possible platelet tumbler sequences is counteracted the state of the art is substantially increased, since according to the invention in at least one scan plane with a key different types of platelet tumblers encoded, so can be queried on their counter-scanning of arranged on the key or reversible key for both types of platelet tumblers scanning.

The variability of the coding and thus the security against breakage of the closing devices of the locking systems can, as will be explained in more detail below, be further increased.

Force direction of the spring loaded slide tumblers:

First of all, it is expressly pointed out that the four types of plate tumblers 5A, 5B, 5C, 5D always spring-loaded relative to the axial cylinder axis 7 of the cylinder core 4 by an arranged spring element 3A in both directions of the first radial direction of movement 7.1 and let move the second radial direction of movement 7.2.

This possibility is indicated by the double arrows in FIG. 2B illustrates that show that already the platelet tumblers 5A, 5B of the prior art in both directions of the radial directions of movement 7.1 and 7.2 are spring-loaded movable.

This also applies to the new plate tumblers 5 of the third and fourth type 5C, 5D, which are not described in the prior art.

In the preceding examples, for the sake of clarity, the types of plate tumblers 5A, 5B, 5C, 5D were always loaded in the same direction of the first and second radial directions of movement 7.1 and 7.2.

A spring element 3A assigned to each wafer tumbler 5 engages a projection 5-1 (not shown in the described inventive figures of the five embodiments) (however, in FIG FIG. 3 shown). The arrangement of the projection 5-1 and the determination of the direction of force of the spring element 3A can ensure that a platelet tumbler 5 is spring-loaded in one or the other direction of the radial directions of movement 7.1 and 7.2 movable.

Arrangement of the plate tumblers:

Secondly, it is expressly referred to again that the four types of die tumblers 5A, 5B, 5C, 5D as in FIG. 2B shown, in the longitudinal direction of the key 2 in the scanning planes 11 _n always in the same position or with respect to their longitudinal axis rotated by 180 ° can be arranged.

In the foregoing examples, for the sake of clarity, the types of the plate tumblers 5A, 5B, 5C, 5D have always been arranged in the same position relative to the key 2, so that the respective type 5A, 5B, 5C, 5D seen in the longitudinal direction of the keyway 6 , (as in FIGS. 2A, 2B is visible) are arranged.

An exception is the third embodiment of the first embodiment (see FIGS. 4E and 4F ).

In this embodiment, the second type 5B slide tumblers 5 have been offset by 180 ° in every other scanning plane 11 ₁ to 11 ₁₀ , so that the tumbler groove 5B-1 once scans the counter-scanning points of the first rib edge 9A in the scanning planes 11 ₁ , 11 ₃ , 11 ₅ , 11 ₇ , 11 ₉ with the scanning points 12 ₁ , 12 ₃ , 12 _5, 12 ₇ , 12 ₉ and another times the counter-scanning points of the first opposing rib flank 9A 'in the scanning planes 11 ₂ , 11 ₄ , 11 ₆ , 11 ₈ , 11 ₁₀ in the sampling 12 12 _, 12 ₄ , 12 ₆ , 12 ₈ , 12 ₁₀ can query.

In this embodiment, it is already shown that, depending on the arrangement of the platelet tumblers 5, more than two flanks of a key 2 can be pulled by the respective platelet tumblers 5 of a closing device for scanning the counter-scanning points.

By coordinated with the key 2 modified arrangement of the platelet tumblers 5 and selection of the direction of force of the spring elements 3A thus beyond two-rail locking systems beyond multi-track locking systems can be formed.

An example: A four-rail locking system shows starting from Figure 6D, 6E . 6F the Figure 8A ,

The top two pictures of the FIG. 6F show that the control edges 8A and 10A are used for interrogating the counter-scanning points of the first type 5A and the third type 5C wafer tumblers 5.

The rectangles of the Figure 8A show the sampling 12 _n , with which the Gegenabtaststellen the platelet tumblers 5 of the first and third type 5A, 5C by the selectable radial direction of action 7.1 and 7.2 of the spring elements 3A and by an about the longitudinal axis by 180 ° pivoted arrangement of the platelet tumblers 5A, 5C are scanned.

The arrows 7.1 and 7.2 show the effective direction, the sampling points 12 _{n of} the key 2, the respective spring element 3A opposite to the platelet tumblers 5 of the first and third type 5A, 5C exercise.

The first type 5A wafer tumblers 5 are replaced as shown in FIG Figure 8A , Upper figure showing the broad outer side 2B of the key 2, by means of the first groove flank 8A in the scanning planes 11 ₁ , 11 ₂ , 11 ₅ , 11 ₆ scanned in a direction of the radial direction of movement 7.1, that is pushed away. The plate tumblers 5 of the first type 5A engage with their tumbler lugs 5A-1 on the first groove flank 8A of the first control track 8.

The first type 5A wafer tumblers 5 are used in accordance with Figure 8A , third illustration from above, showing the opposite broad outside 2B 'of the key 2, by means of first opposing groove flank 8A 'in the scanning planes 11 ₃ , 11 ₄ , scanned in the opposite direction of the radial direction of movement 7.1, that is pushed away. The plate tumblers 5 of the first type 5A engage with their tumbler lugs 5A-1 on the first opposing groove flank 8A 'opposite first control track 8'.

The third type 5C wafer tumblers 5 are replaced according to Figure 8A , Second figure from above, showing the narrow outer side 2S of the key 2, by means of the control edge 10A in the scanning planes 11 ₇ , 11 ₉ , scanned in a direction of the radial direction of movement 7.2, that is pushed away. The third-type disc tumblers 5C engage with their tumbler stages 5C-1 on the first control land 10A of the third control track 8.

The third type 5C wafer tumblers 5 are replaced according to Figure 8A , lower figure showing the opposite narrow outer side 2S of the key 2, by means of the opposite control edge 10A 'in the scanning planes 11 ₈ , 11 ₁₀ , scanned in an opposite direction of the radial direction of movement 7.2, that is pushed away. The third-type die tumblers 5C engage with their tumbler stages 5C-1 on the first opposing control land 10A 'of the third opposing control land 8.

Thus, four flanks, the flanks 8A, 8A ', 10, 10A' are used to scan the counter-scanning locations of the first and third type platelet tumblers 5, 5A, 5C.

For the purposes of the invention is in Figure 8A in the seventh scanning plane 11 ₇ again a scanning point 12 _{7 of} the key 2 is shown with a two-point stroke sequence in which variable selectable whether a counter-scanning of a platelet guard of the first type 5A or a counter-scanning of the platelet Locking device of the third type 5C should be interrogated.

In the example shown 12 _2, 11 ₇ platelet tumblers 5 of the third type 5C was selected in the sampling 12. It would also be possible according to the invention to arrange a small plate tumbler 5 of the first type 5A in the lock cylinder 3, 4 or 3, 4A in the scanning point 12 _2, 11 ₇ , without having to make changes to the key 7.

Another example: A six-rail locking system shows starting from Figure 6D, 6E . 6F the FIG. 8B ,

The top two pictures of the FIG. 6F show that the control edges 8A and 10A are used for interrogating the counter-scanning points of the first type 5A and the third type 5C wafer tumblers 5.

The rectangles of the FIG. 8B show those sampling 12 _n , with which the Gegenabtaststellen of the platelet tumblers 5 of the first and third type 5A, 5C by the selectable radial direction of action 7.1 and 7.2 of the spring elements 3A and by a longitudinal axis about 180 ° pivoted arrangement of the platelet tumblers 5A, 5C are scanned.

The arrows 7.1 and 7.2 again show the direction of action, the set points 12 _{n of} the key 2, the respective spring element 3A set opposite to the platelet tumblers 5 exercise.

The effective direction of the spring elements 3A is opposite Figure 8A continues to vary.

The first type 5A wafer tumblers 5 are replaced as shown in FIG FIG. 8B , Upper figure showing the broad outer side 2B of the key 2, scanned by the first groove flank 8A in the scanning planes 11 ₁ , 11 ₅ , 11 ₆ and by means of the second groove flank 8B in the scanning plane 11 ₂ in both possible directions of the radial direction of movement 7.1 that means pushed away. The plate tumblers 5 of the first type 5A engage with their tumbler lugs 5A-1 at the first groove flank 8A and the second groove flank 8B of the first control track 8.

The first type 5A wafer tumblers 5 are used in accordance with FIG. 8B Third, from above, showing the opposite broad outer side 2B 'of the key 2, by means of the first opposite groove flank 8A' in the scanning plane 11 ₃ and by means of the second opposite groove flank 8B 'in the scanning plane 11 ₄ in both possible directions scanned radial direction of motion 7.1, that is pushed away. The first-type plate tumblers 5A engage with their tumbler lugs 5A-1 on the first opposite groove flank 8A 'and on the second opposite groove flank 8B' of the first opposite control track 8 '.

The third type 5C wafer tumblers 5 are replaced according to FIG. 8B , Second figure from above, showing the narrow outer side 2S of the key 2, by means of the control edge 10A in the scanning planes 11 ₇ , 11 ₉ , scanned in a direction of the radial direction of movement 7.2, that is pushed away. The third-type disc tumblers 5C engage with their tumbler stages 5C-1 on the first control land 10A of the third control track 10.
