The invention concerns a security reversible key with an assigned cylinder, a locking system with security reversible keys for locking systems, and a method for their manufacture. Such keys and locking systems are known, where the keys with a high degree of security and a correspondingly high number of possible coding permutations. The keys have at least three, and preferably at least four coding tumbler pin rows. The tumbler row pins are located on the flat sides of the key in order to make the best possible use of the available key surface, as well as the corresponding space requirement for the tumbler pin rows in the cylinder. Keys with additional security elements are also known, which once again require a certain amount of space.
From U.S. Pat. No. 5,438,857, such a key is known, with an insertion blocking system as an additional security element. In the '857 key an additional control face is located on the key that, by means of an assigned control pin at the cylinder entrance, prevents the insertion of a wrong key. This control pin is longer than a coding pin and extends beyond the central bisecting plane of the key. The control face is arranged at the tip of the key and rising, and it correspondingly also extends beyond the central bisecting plane of the key and lifts the control pin and pushes the control pin out of the way. As a result of this, the control pin prevents the insertion of keys without a correct control face. The control faces can already be affixed to the key blank and with this enable a protection of the blank.
These known high-security keys and systems with high-security keys are also always limited by the space available for the coding and security functions on the key and in the cylinder. Their manufacture calls for a central production, which limits, renders more difficult, and delays the world-wide universal application of such systems. Also, an optimum design for installations and applications of any kind is severely restricted by this.
It is an objective of the present invention to create a security reversible key with an assigned cylinder. More specifically, it is an objective of the invention to provide a locking system with security reversible keys and assigned cylinders, which can be utilized as a world-wide unique locking system, with higher permutation capacities for any kind of application, with enhanced security and copy protection as well as with new possibilities of being in a position to separate any kind of market area and application world-wide, and whereby, without any additional space requirement on keys and cylinders, a higher security and a greater number of permutations is achieved. A further objective of the present invention is a manufacturing method for a system of this kind, which can rapidly and universally be brought into use and applied world-wide.
In accordance with the present invention, a security reversible key has an assigned cylinder, a locking system has security reversible keys with assigned cylinders, and a method is provided to manufacture such keys. With the new additional security element “blocking code”, which comprises a coded blocking groove and an assigned pair of blocking tumbler pins, without any additional space requirement on the key and in the cylinder, i.e., with the existing coding positions on the key and the existing pin rows and positions in the cylinder, an additional insertion blocking system as well as a higher number of permutations and applications are achieved. With the division into areas on the key, whereby the first area with additional security elements defines an unequivocal segmentation into independent market areas, a system is created that corresponds to the above named objective and which can be realized with the new, multi-step manufacturing process.
Especially with the new additional security element “blocking code”, which comprises a coded blocking groove and an assigned pair of blocking tumbler pins, without any additional space requirement on the key and in the cylinder, i.e., with the existing coding positions on the key and the existing pin rows and positions in the cylinder, an additional insertion blocking system as well as a higher number of permutations and applications are achieved.
These and further features of the invention are apparent with reference to the following description and drawings, wherein:
a shows coding rows with coding positions for two bore patterns on one key;
b shows on a key a division into areas, with a first area with additional security elements;
c shows a further example of a division into areas;
d shows a segmentation of market areas and distributor areas on a key;
e shows a connection between division into areas and segmentation of market areas;
a, as an example, illustrates a safety turning-key S with four pin rows A1 to A4 and with 22 coding positions Pi, each one for a bore pattern left (L) and a bore pattern right (R). The coding row A2 on the key S here has the positions R1 to R5 for the bore pattern R and the positions L6 to L11 for the bore pattern L. On the keys, all positions of both bore patterns can be coded. For example, there are keys with bore pattern left, keys with bore pattern right and also keys with the two bore patterns R+L. In the assigned cylinder Z, however, for reasons of space for the pins, only every second position and, with this, only either a bore pattern R or a bore pattern L can be equipped with tumbler pins (in the same area). The first coding position P1 (=L11) on the tip of the key here corresponds to the rearmost tumbler pin position P1′ in the cylinder with respect to the direction of insertion x of the key S.
b illustrates the locking system in accordance with the invention on a key S, whereby on the key at least two areas are defined with a first area G1, in which at least two additional security elements with a higher degree of difficulty to manufacture are foreseen, and with a second area G2, in which a simple basic coding Cod1 is foreseen. With the first area G1 an unequivocal segmentation into independent market areas Mi=M1, M2, etc. is defined.
Also illustrated here are additional security elements, which in the following are more accurately defined: a blocking code BC, a second coding Cod2, preferably with a narrow milling, an insertion blocking system by means of a control face and control pin KF/KS and a flank control of Cod2 by means of a flat pin 23. The simple basic coding Cod1 is, for example, a coding by means of bores, which is relatively easily implementable anywhere decentralized.
c depicts a different division into areas, whereby the area G1 can be divided into several part areas G1.1, G1.2, etc. Depending on the application and on the desired system design, the area G1 can, for example, encompass a whole coding row A1. In doing so, also all security elements are affixed in this one coding row. In a different advantageous variant, for example, also parts of areas with positions at the very front of the key of two coding rows (A1, A2) can form the area G1, whereby both parts of areas G1.1, G1.2 can each respectively have a blocking code BC.
d illustrates the division into several independent market areas Mi=M1, M2, etc., as well as the possible further sub-division of each market area into parts of market areas MMi on the key, which for example, correspond to independent distributor areas or fields of application for installations and objects, etc. The market areas Mi are defined with the area G1. The parts of areas MMi can be defined with parts of the area G1 or also with parts of the area G2 or they can equally encompass parts of the areas G1 and G2.
e illustrates, for example, a connection between the areas G1, G2 on the key and the unequivocal separation in the market area Mi, parts of market areas MMi as well as the further subdivisions for objects MMi.i. This is further explained hereinafter with reference to FIG. 18.
Advantageously, the area G1 contains at least three security elements Vi. Particularly important and advantageous is the new additional security element “Blocking Code”. In the case of the blocking code BC, as an additional coding and security function in accordance with the invention explained in
The
a illustrates a pair of blocking tumbler pins BZ, BG with blocking code B1, the length lb of which is greater than the distance db of the blocking groove from the cylinder housing 10. With this, the complete insertion of the key S1a into this cylinder is blocked. FIG. 8b in contrast illustrates a pair of blocking tumbler pins BZ, BG with a blocking code B2, which corresponds to the blocking code B2 of the blocking groove BN and which, therefore, can be completely inserted. This in the schematic diagram of
The
A further important additional security element, which can also be assigned in the same tumbler pin row, is illustrated in
Advantageously therefore in a tight space and in a single tumbler pin row the following very effective security elements can be combined: in addition to the blocking code BC in accordance with the invention, a second coding Cod2 with a narrow milling, an insertion control by means of control pin KS and control face KF as well as a flank control of the narrow coding Cod2 by means of a flat tumbler pin 23.
In the case of somewhat bigger keys, it is also possible to foresee more than four rows of tumbler pins.
a for this purpose illustrates an example with five rows of tumbler pins A1 to A5 and

Defined with this are two independent market areas M1, M2 With three, resp., two derivations. The key S3, e.g., opens the cylinders Z1 and Z3.
Defined with this are four independent market areas M1 to M4, each with three derivations.
For example, the key S11abc opens the cylinders Z11a, Z11b, Z11c.
The variables Vi and security elements manufactured in the various areas Gi and in the corresponding manufacturing steps Hi, for example, are also indicated in the table.
With the manufacturing of keys and cylinders of a locking system with at least two areas G1 G2 on the keys, first the first area on the keys is manufactured (controlled and authorized) at a central place of manufacture H1 and the coding Cod1 of the keys of the second area G2 and the equipping of the cylinders with corresponding pins can subsequently take place at a local representative: H2.
The manufacturing can take place in at least two steps in different places, whereby first variables with a higher degree of difficulty HS of the area G1 are manufactured in a central location and subsequently variables with a lower degree of difficulty of the area G2 are manufactured decentralized or locally.
The manufacturing of the keys can also take place in three steps, whereby first the first area G1 with variables Vi of the highest degree of difficulty is manufactured centrally H1; thereupon a further area G1/2 with variables with a lower degree of difficulty is manufactured regionally: H1/2 and finally the coding G2 with the lowest degree of difficulty of the area G2 is manufactured locally at the place of use H2.
In a further development of the system, the manufacturing of the area G1 can also take place decentralized. To implement this, manufacturing programs and the authorization “aut” can be controlled and checked from the central location SS (system owner).
With the system in accordance with the invention and the manufacturing methods a universal differentiation of market areas and parts of market areas as well as a rapid local manufacturing are made possible.
