Abstract

The security reversible key with an assigned cylinder (Z) has a blocking groove (BN) with a coded blocking depth (B 1 , B 2 , B 3 ), which runs parallel to the axis of the key (x) from the tip of the key to at least the first position (P 1 ) of a row of tumbler pins (A 2 ) on the key. In the assigned cylinder, at least at the rearmost coding position (P 1 ), a pair of tumbler pins corresponding to the blocking groove (BN) with a blocking tumbler pin (BZ) and an extended blocking counter pin (BG) are foreseen, whereby the blocking counter pin (BG) impinges on the cylinder housing ( 10 ), if the blocking groove is insufficiently deep and, with this, the complete insertion of a key with an insufficiently deep blocking groove is blocked by the pair of blocking tumbler pins. Simultaneously, the blocking tumbler pin (BZ) with the counter pin (BG) at the position (P 1 ) also serves as coding tumbler pin. In the case of the locking system with security reversible keys for locking installations at least two areas are defined, In a first area (G 1 ) several additional security elements and a blocking code function are provided while, in the second area (G 2 ), a more simple basic coding are foreseen. With the first area (G 1 ), an unequivocal segmentation into independent market areas (M 1 , M 2 , M 3 ) is defined and, with this, a world-wide unique locking system with enhanced security and applicability is created.

Fig. 1a shows as an example a safety turning key S of a locking system with four tumbler rows A1 to A4 and with 22 coding positions Pi, each for one Drilling pattern left (L) and drilling pattern right (R). The coding series A2 am Key S here has the positions R1 to R5 for the drilling pattern R and the Positions L6 to L11 for the hole pattern L on. All can be at the keys Positions of both hole patterns are coded, i. there are keys with hole pattern right, key with hole pattern left and key with both hole patterns R + L. However, in the associated cylinder Z may be due to space limitations for the tumblers only every second position and thus (in the same area) only either a hole pattern R or a hole pattern L be equipped with tumblers. The first encoding position P1 (= L11) at the key tip corresponds to the rearmost tumbler position P1 in the cylinder with respect to the key insertion direction x.

Fig. 1b illustrates the inventive closing system on a key S, wherein at least two areas are defined on the key, with a first area G1, in the at least two additional security elements with higher Difficulty are provided for production, and with a second area G2, in which a simpler basic coding Cod1 is provided, with the first area G1 a unique segmentation into independent market areas Mi = M1, M2, etc. is set. Also additional security elements, which in The following are more specifically defined: a block code BC, a second coding Cod2, preferably with narrow milling, an insertion lock using control surface and control pin KF / KS and a flank control of Cod2 by means of a flat tumbler 23. The simple basic coding Cod1 is e.g. a Coding by drilling, which relatively simple, decentralized everywhere executable is.

Fig. 1c shows another area division, wherein the area G1 in several Divisions G1.1, G1.2, etc. may be divided. Depending on applications and desired system design, the range G1 may e.g. also a whole Comprise tumbler series A1. Here are all security elements in this attached a tumbler row. In another advantageous variant can e.g. also subareas with foremost positions at the top of the key of two tumbler rows (A1, A2) form the area G1, e.g. both Subareas G1.1, G1.2 may each have a block code BC.

Fig. 1d illustrates the division into several independent market areas Mi = M1, M2 etc. as well as the possible further subdivision of each market area into market subareas MMi, e.g. in independent dealer areas or application areas for facilities and objects, etc. The market areas Mi become with the area G1 established. The subareas MMi can be defined with parts of the area G1 or with parts of the G2 range or they can also be parts of the Include areas G1 and G2.

For example, Fig. 1e illustrates a relationship between regions G1, G2 at the key and the clear separation in the market area Mi, Submarket areas MMi and the further subdivisions for objects MMi.i. This is further explained to Fig. 18.

Advantageously, the area G1 contains at least three security elements Vi. Particularly important and advantageous is the new additional security element "Block code". When explained for Fig. 2 block code as additional coding and Safety function remains the coding position P1 and its function on Key S and received on cylinder Z.

Fig. 2 shows schematically the operation of the inventive block code BC on a key S and on an associated cylinder Z. The Spatial directions are denoted by x, y, z below and x is the key or cylinder axis. On the key a Blocknut BN is mounted or milled, which runs parallel to the key axis x and which at least until the first Coding position P1 runs. In the associated cylinder Z is corresponding at least at the rearmost coding position P1 one of the block groove BN corresponding tumbler pair with a sprung Blockzuhaltung BZ and with a prolonged block countermotion BG provided. The block groove has a coded block depth B1, B2, B3 and this is the length of the 1b Block tumbler pairs (BZ + BG) coded such that 1b the distance db of the block groove BN from the cylinder sleeve 10 corresponds, i. that the block tumbler pair (or Block pin pair) with little play fits into the block groove. When inserting the Key results in the following sequence (a - b - c): The block lock BZ is on an inlet surface 6 of the key raised to the height of the block groove BN and passes with little play to the cylinder sleeve 10, the block groove to the corresponding coding position P1, wherein the block tumbler BZ in this first Coding position with a certain code level, here e.g. C2, is lowered. In In this position P1, the block tumbler pair BZ, BG acts as normal Coding position with respect to turning the cylinder, which with correct coding the shear line 9 must release. If the block groove BN is too low or one has false coding Bi, so is the block counterhold BG at the Cylinder sleeve 10 and the further insertion of the key is at the Entry surface blocked (if 1b is greater than db, see Fig. 8a). The block code thus gives an additional safety function by the whole-plugging can be prevented with additional coding levels (Bi) of the block groove, wherein the previous coding function is maintained at position P1. Moreover, will neither at the key, i. at the key positions still in the cylinder additional space needed for the block code. At the cylinder becomes simply one previous normal Codierzuhaltung replaced by the special Blockzuhaltung.

FIG. 3 shows possible block stages Bi with a depth tb in comparison to FIGS Coding stages Ci with the code depths tc relative to the key surface 7. In In the following examples, coding levels C1 to C4 (e.g. Gradations of 0.35 mm) as well as three block steps B1, B2, B3 with block depths of e.g. 1.05, 0.55 and 0 mm, with a block stage B3 with depth 0 mm can no longer exercise a blocking function. The block depths Bi can also correspond to the code depths Ci, e.g. C1 to C4 and B1 to B4. In one Another example is five coding stages C1 to C5 with four block stages B1 to B4 combined, e.g. with step distances of 0.3 mm of the Ci and 0.4 mm of Bi. According to combination rule for the block stages Bi with the Coding stages Ci, the code depth tc of the coding stages Ci may not be smaller as the block depth tb of the previous block groove Bi. Thus, in this example the block stage B3 combined with subsequent coding levels C3, C2 or C1 become.

4, 5 and 6 show various possible tumbler forms (FIGS. 4a, b, c), associated forms of Blocknuten BN (Fig. 5a, b, c) and the tumblers associated coding forms (Fig. 6a, b, c). Fig. 4a shows a conventional conical tumbler 21, e.g. for a basic coding Cod1, which by simple holes can be produced (Fig. 6a). Fig. 4b shows a narrow cylindrical Zuhaltungsform 22 with correspondingly narrow coding grooves (Fig. 6b), whose Production e.g. require a difficult to copy, complex milling process and which e.g. can be used as the second coding Cod2. Fig. 4c shows a Flat tumbler 23, which, for example, for the edge control of a narrow Milling coding (Fig. 6b) can be used, as explained later becomes. There are other Zuhaltungsformen possible and known, which in the Principle of a combination of cylindrical and conical sections put together. The block groove shapes and the coding shapes can be formed differently and thus complicate the copying and also cause additional concealment of Codierformen.

Figs. 7a, b, c illustrate an example of a block groove extending across the four frontmost coding positions Pi = L11, R5, L10 and R4 of two drilling patterns R, L extends and which correspondingly several differently coded areas BN. 1 to BN4 have. As a rule, it should be noted that the depth tb of the block grooves from one position to the next position remains the same or gets smaller (i.e. can become larger) and that also the width bb of the block grooves of one Position to the next stays the same or gets smaller. This results in three Block stages B1 to B3 and with two Blocknutbreiten bb1 and bb2 the illustrated Block stages Bi, bbi of the four block groove areas BN1 to BN4.

FIG. 8 shows the function of the block code in three-dimensional representation and Fig. 9 Blocknutformen and the subsequent coding recesses, which correspond to the example of FIG. 14. In Fig. 8a, b a key S1a is shown with a block groove, which has a block level B2 and with subsequent Coding positions L11 and R5 having the codes C1 and C2 (corresponding to the key S1a of Fig. 14).

Fig. 8a shows Blockzuhaltungspaar BZ, BG block code B1, whose length 1b is greater than the distance db of the block groove of the cylinder sleeve 10. This will to block full-insertion of the key S1a in this cylinder. Fig. 8b shows in contrast, a Blockzuhaltungspaar BZ, BG with a block code B2, which the block code B2 corresponds to the block groove BN and which thus completely plugged can be. This corresponds to the key S1a in the diagram of FIG. 14, which the cylinder Z1 (with coding C1 at the position R5) opens.

FIGS. 9a to 9d show the keys S1, S2, S3 and S1a differently coded block grooves and positions L11 and R5. This also corresponds to the Closing function diagram of Fig. 14, which indicates which key-cylinder combinations open and lock what.

Fig. 10 shows a possible additional security element known per se Insertion lock by means of control surface KF at the key tip and associated Control pin KS in the cylinder. This control surface KF extends over the median plane 5 the key, as well as the control pin KS, which on the rising Control surface KF hits and must be pushed by this out of the way, so the key can be inserted. A key without proper control surface or only with normal inlet surfaces 6 hits with its tip on this Control pin KS, so that this prevents the insertion of the key. This is a completely different arrangement and mode of action than according to the inventive Block code that does not need special control surfaces, but with each existing key entry surface 6 works. Advantageously, however the new block code with the block tumblers BZ with this known Insertion lock combined by control surfaces KF and control pin KS and in the even in the same tumbler series (e.g., A2), where the control pin KS somewhere before the Blockzuhaltungspaar BZ, BG in the cylinder is arranged.

Another important additional security element, also in the same Tumbler row can be arranged, is shown in Fig. 11a, 11b. These illustrate a flank control on a narrow Codingfräsung Cod2, which is exerted by a flat tumbler 23. The flat tumbler 23 (see, e.g., FIG. 4c) has a diameter d2 which is greater than the width d1 of Milling coding, so that the flat locking rests on the key surface 7, as shown in Fig. 11a. On the other hand, in a basic coding Cod1, e.g. According to Fig. 6a, with necessarily wide holes d3 the flat tumbler 23rd sink into these wells according to FIG. 11b, whereby the shearing line 9 of the Cylinder is blocked. Thus, e.g. a simple fake hole instead the authorized, much more elaborate narrow milling coding Cod2 detected and the function of such a counterfeit key can be prevented.

Advantageously, thus, in a small space and in a single Coupling series combines the following very effective security elements become: in addition to the inventive block code BC a second coding Cod2 with narrow milling, a plug-in control by means of control pin KS and Control surface KF and a flank control of the narrow code Cod2 by means of a flat tumbler 23.

Fig. 12 shows a cross section through a security reversible key with four Tumbler rows A1 to A4 in a cylinder according to the example of FIG. 1. The series A1 is here with narrow milling coding Cod2 and with a Block tumbler pair BZ, BG formed. The rows A3 and A4 (and optional also the series A2) are here with a simpler basic coding Cod1 educated. Importantly, the given key surface and the space in the cylinder best exploit for coding positions and security elements. To necessarily (at least two) Zuhaltungsreihen also on the Flat sides of the key can be arranged.

For larger keys, more than four rows of tumblers can be used be provided.

13a shows an example with five tumbler rows A1 to A5 and FIG. 13b an example with eight Zuhaltungsreihen A1 to A8, which, however, only so far with Tumblers in the cylinder can be fitted, as there is space for it. Thanks to the use of narrow codings, however, it is also possible here at the Key all eight rows to code. This results in a high number accordingly possible permutations and other safety reserves. In principle, can Here, too, a block code be provided at the beginning of each tumbler series Ai.

In Figs. 14 to 17 are closing function diagrams with various Combinations of block codes Bi and codes Ci of the following Positions Pi shown. In the column on the left are the codes Bi, Ci the Key Si indicated and in the row above the codes of cylinders Zi. The Keys may include drilling patterns R or L, or R + L (both) while the cylinders can only contain one drilling pattern R or L. The diagram shows with "X", whether a combination fits key / cylinder, i. if the key is the relevant cylinder opens. Lock all other combinations. FIGS. 14 to 17 show how with a few block codes Bi and then Position coding Ci different market areas Mi clearly from each other are distinguishable and, as in a market area, several derivatives, i. Hierarchical distinctions that can be realized by keys in a system.

The diagram of Fig. 14 (which corresponds to Figs. 8 and 9) shows codings Ci with two drilling patterns and two positions
P1 = L11 and P2 = R5
with 5 assembly variants with block stages Bi = B1, B2, B3 of the block grooves
and coding stages Ci = C1 and C2.
This will be two independent market areas M1, M2
defined with three or two derivatives.
The key S3, for example, opens the cylinders Z1 and Z3.

Fig. 15 shows only one hole pattern L with block code over two positions
P1 = L11 and P2 = L10
with block steps B1, B2, B3
and with coding levels C1, C2.
This will become four independent market areas M1 to M4
defined with three derivatives each.
The key S11abc, for example, opens the cylinders Z11a, Z11b, Z11c.

Fig. 16 shows a drilling pattern L with two positions
P1 = L11 and P2 = L10
with block code B1, B2, B3
and coding levels L11 = C1 and L10 = C1,
wherein five derivatives are generated with the block stages in one market area.
That means key S11abcde opens the five cylinders Z11a to Z11e
and the key S11a only opens the cylinder Z11a.

FIG. 17 shows an example with only one position P1, however, in two tumbler rows A1, A2. Both positions P1 are coded C1,
while with the block stages B1, B2, B3 of Blocknuten
three independent market segments M1, M2 and M3.
The key S1 only opens the cylinder Z1, S2 only opens Z2 and S3 only opens Z3.

FIG. 18 illustrates an organization of the closing system according to the invention Security reversible keys in a hierarchical scheme. The system owner SS (e.g., a manufacturing company) represents the highest hierarchical level that the Market areas Mi = M1, M2, etc. are defined and authorized, being a market area e.g. a country or a general agency. In the market areas will be further subregions MMi are defined and separated, e.g. for different dealers or Investments in this area. Another stage MMi.i can e.g. individual objects define. This is determined by the codings of the areas G1 and G2.

FIG. 19 schematically illustrates a manufacturing method for keys of an inventive device Systems with manufacturing levels H, G key and key areas with the manufactured variables Vi in the areas G. In general, the Production H with decreasing difficulty level HS at lower levels or decentralized.

The variables Vi and security elements fabricated in the different regions Gi and the corresponding manufacturing stages Hi are also indicated in the table, for example.
With the production of keys and cylinders of a locking system having at least two areas G1, G2 on the keys, first the first area on the keys at a central place of manufacture is H1, and the coding Cod1 is the key of the second area G2 and the Equipping the cylinders with corresponding pins can then be carried out decentrally by a local representative: H2.

Production may be made in at least two stages or locations, first by making variables of higher difficulty HS of the range G1 in a central location and then variables of lower difficulty of the range G2 decentrally or locally.
The production of the keys can also be done in three stages, first the first area G1 with variables Vi of the highest difficulty central: H1, then another area G1 / 2 with variables with a lower degree of difficulty regional: H1 / 2 and finally the coding G2 with The lowest level of difficulty of the G2 area can be fabricated locally at the point of application: H2.
In a further development of the system, the production of the G1 area can also be decentralized. For this purpose, production programs and the authorization "aut" can be controlled and controlled from the central station SS.

With the inventive system and the manufacturing process is a universal distinction between market areas and subareas as well as rapid local production allows.
