Definitions

  • the invention relates to a device by means of which personal identification numbers (PIN) can be stored.
  • PIN personal identification numbers
  • PINs have become indispensable for modern banking services.
  • other areas e.g. B. in communication technology (mobile phones)
  • the PIN is also used more and more often.
  • the purpose of these PINs is basically to prevent misuse by unauthorized third parties.
  • EP 0 382 410 A2 describes a device for the encrypted storage of PINs. It consists of several number carriers arranged immovably next to one another on a carrier. Another mechanical marking device is known from DE 92 00 109 U1, in which the tabular data carrier can be individually is writable.
  • DE 43 03 888 C1 describes a coding / decoding card in which the two number carriers are detachably attached to the common base body in a form-fitting manner. With all of these memory devices, the user must remember a coding in order to be able to determine his PIN in a more or less cumbersome manner.
  • PIN markers are also designed as electronic devices in a form similar to small pocket calculators and indeed allow secret numbers to be encrypted, but only with battery or solar operation and the secret number being typed in. Taking these electronic devices with you is not comfortable because of their size, and they are also relatively sensitive to impact.
  • the invention is therefore based on the object of creating a space-saving, shock-insensitive, very safe device of the type mentioned, and this object is achieved according to the invention by the combination of the features specified in claim 1.
  • the object of the invention is purely mechanical and z. B. in the form of a keychain easy and space-saving. It is only necessary to impress a single, freely definable number, the so-called CODE number, with the help of which the corresponding PINs can then be read off.
  • This CODE number can e.g. B. the birth date of the favorite actor (eg 4862 is the CODE number for the date 04.08.1962).
  • the secret, freely definable code number can be set in a matter of seconds, and then several PINs can be easily read. Since it is a purely mechanical object, use is independent of battery energy or other energy source with optimum robustness guaranteed at all times.
  • the principle of the invention is based on the possibility of being able to define sequences of numbers on movable objects, so-called number carriers, the number carriers having to be adjustable relative to one another.
  • the number of these movable number carriers determines the max. possible number of digits of the PINs.
  • 4-digit PINs are used, so that the PIN flag should also be executed with 4 number carriers.
  • the individual number carriers only have to be set so that the CODE no. appears on a row. Now the PINs are easy to read on the following rows.
  • the PIN flag can e.g. B. in the manner of a combination lock z. B. for bicycle locks, but with the essential difference that the numbers from 1 - 10 are noted in the usual order (0-1-2-3-4-5-6-7-8-9) and also with the There is no mechanical unlocking of the PIN marker, only numbers are read.
  • the numbers are freely definable by the user on the PIN marker. If e.g. B. 12 digits can be provided for the application of numbers, a personal CODE number and max. eleven PINs are encrypted.
  • the sequence on each individual payment medium is to be defined, starting with the personal CODE number and then the PINs in sequence, whereby the sequence on the individual number carriers must remain the same. If there are still places left (e.g. if there are twelve places on a number carrier, a CODE number and four PINs, there are seven places left), these must be filled with numbers that do not yet exist to ensure optimum security to ensure. It should be noted that the numbers are not used in order, but randomly.
  • the number of digits on a number carrier should therefore also be more than ten digits, since it cannot be ruled out that the same number will occur at two or more secret numbers in the same place. In such a case, if there are only ten digits, not every number is present on a number carrier. In the cases in which the corresponding digit of the CODE number corresponds to the digit of a PIN, which should be avoided, however, it must also be noted which digit follows the corresponding digit of the CODE number. However, this is not difficult, as it will be very easy to remember the correct setting with a maximum of two options.
  • FIG. 2 shows an exploded view of a PIN marker with number loop-shaped number carriers
  • FIG. 3 shows an exploded illustration of a PIN flag with rod-shaped number carriers
  • FIG. 4 shows a plan view of a PIN marker with number disk-shaped ring disks
  • FIG. 5 shows a side view of a modification of the PIN flag according to FIG. 1;
  • FIG. 6 shows a perspective illustration of a number chain to be applied to the PIN marker according to FIG. 5;
  • FIG. 7 shows a perspective illustration of two number plates of the number chain according to FIG. 6 during different stages in their connection.
  • Pos. 1 is a shaft for receiving number carriers 2 and intermediate rings 4.
  • the number carriers 2 and intermediate rings 4 are designed as rotating parts that can rotate on the shaft 1. This achieves the necessary adjustment of the combination.
  • the individual numbers applied to the 12-square faces of the number carriers Since the sequence of the numbers has to be determined by the user, it is expedient to have the numbers applied by the user himself. This can be done by writing, engraving, wrapping, scratching off scratch numbers, inserting numbers, sticking on stick numbers, etc.
  • the 12-edge in the variant shown therefore has 12 digits, the 12-edge being chosen only for optical reasons and to simplify the application of numbers.
  • a round part is also conceivable, on which individual fields are marked, or one without any marking.
  • a knurled ring is provided on each number carrier 2, with the aid of which the twisting of the individual number carriers 2 is to be facilitated.
  • This knurled ring which is firmly connected to the 12-edge or can be produced in one piece with the 12-edge, is expediently larger in diameter than the outer edges of the 12-edge in order to facilitate twisting.
  • protective rings 3 made of transparent material, e.g. B. transparent plastic rings, are applied.
  • the intermediate rings 4 are provided for safety and optical reasons. Since a rasterization of the number carriers makes it easier to read the PINs, the number of latching positions having to correspond to the number of digits on each number carrier, this is preferably used. Without intermediate rings, an imprint could form between one number carrier and the next number carrier in the most frequently used setting, namely the setting for reading the PINs, and could then be recognizable. Therefore, the locking position is defined from one number carrier to the next via the intermediate rings. Since the intermediate rings are not connected to the number carriers, there is none clear locking position given with your own combination.
  • the screening can be carried out in the form of elevations on the intermediate rings and depressions in the number carriers or similar variants.
  • balls can also be used. These balls could be seated in holes in the intermediate rings, the thickness of the intermediate rings being somewhat less than the diameter of the balls. Wells should then be present in the number carriers into which the balls snap.
  • the use of one or more resilient elements is necessary so that the necessary relative movement between the elements to be latched can take place.
  • These resilient elements can be disc springs, spring washers for screw locks, as shown in the drawing at 5, coil springs, elastomer springs, resilient plastic parts, an elastic receiving shaft, elastic number carriers, elastic intermediate rings, protruding elastic protective rings or other resilient elements.
  • All elements are then applied to the common shaft 1 and then connected to a terminating part 6 to form a unit which can be screwed onto a threaded end of the shaft 1 provided with a head at the other end and with a hole in the exemplary embodiment is provided with a key ring for connection.
  • Letters distributed over the circumference can be applied to the head of the shaft 1, which can also be designed as a 12-edge, the order of which (eg A for car, T for telephone, etc.) corresponds to the order of the PINs and their assignment easier.
  • Fig. 2 shows z. B. number carriers in the form of self-contained, endless bands 7, which are applied to a rounded, prismatic carrier body 8 and then shifted all the way around and thereby adjusted or adjusted.
  • a variant with a translatory displacement of rod-shaped number carrier 9 is also conceivable, for example: B. in a similar form to a slide rule. Since in this variant, in contrast to the other variants, there is a beginning and an end for each number carrier 9, for security reasons the number sequences should appear on each number carrier 9 several times and with a different beginning.
  • annular disk-shaped, rotatable number carriers 10 are not arranged axially next to one another, as in the embodiment according to FIG. 1, but rather are arranged concentrically.
  • FIG. 5 represents a modification of the embodiment according to FIG. 1.
  • four annular number carriers 12 with a polygonal cross section are rotatably mounted on a shaft 11, but the shaft 11 is not integral with a head formed, but pressed non-releasably into a bore in a head part 13.
  • an intermediate ring 14 is again rotatably arranged on the shaft 11, and there is also such an intermediate ring 14 and again a spring between the last number carrier 12 shown on the right in FIG. 5 and a closing part 16 15, this time in the form of a coil spring.
  • the end part 16 is also permanently pressed onto the shaft 11 with a bore, whereby a Part of the coil spring 15 is received in an enlarged outer region of the bore in the end part 16.
  • the shaft 11, the head part 13, the end part 16 and the intermediate rings 14 are made of steel in the example, the number carrier 12, however, made of plastic.
  • the twelve-sided number carriers in the example are each provided on their axial side with twelve cone-shaped projections evenly distributed over the circumference, with which they engage in twelve matching holes in the intermediate rings 14 .
  • a number carrier 12 is rotatably connected to an intermediate ring 14.
  • the number carriers 12 are each provided with three blind holes distributed uniformly over the circumference, which lie on the same radius as the projections and the depth of which is dimensioned such that they do not completely accommodate matching balls 17 in diameter, so that a part of each ball 17 protrudes beyond the left end face of the number carrier 12 with reference to FIG. 5 and into which bores of the adjacent intermediate ring 14 receiving the pin-shaped projections of the adjacent number carrier can snap.
  • the number plates 18 are made of plastic and are provided with permanent numbers or embossed numbers during their manufacture.
  • the buyer of a PIN flag receives e.g. B., coherently injected, twelve plates each with the same numerical imprint, ie twelve plates with a "0", twelve plates with a "1", etc. Because the number plates are only connected to one another via predetermined breaking points, the user can Break off any number plates and combine them into a chain with twelve number plates as shown in FIG. 6.
  • the shape of the individual number plates is best shown in FIG. 7. They each have a number on their top. From its one lower edge, on which a molded-on film hinge 19 is located, projects a flat tongue 20, which is shaped with two upwardly projecting, cone-shaped projections 21. At the other end, the undersurface of the number plate 18 is provided with a cutout 22 corresponding to the size of the tongue 20, from which two blind holes 23 indicated by dashed lines extend even further into the interior of the number plate.
  • the arrangement is such that the peg-shaped projections 21 of a number plate 18 can be pressed into the bores 23 of another number plate 18, the tongue 20 fitting snugly into the recess 22, as can be seen in the bottom illustration in FIG. 7.
  • the projections 21 are very firmly or slightly engaged in the correspondingly fitted or slightly undercut holes 23. Because the chain of number plates 18 forms a ring, in the case of parallelepiped-shaped plates relatively large intermediate gaps would result on the outside. In order to obtain an externally essentially closed ring, a longitudinal web 24 is formed on the number plate 18 at the end opposite the tongue 20 on the upper edge, which, according to FIG. 7, bottom illustration, bears against the upper edge of the adjacent number plate 18. This results in an angular position corresponding to the length of the web 24 between the two number plates, and accordingly the tongue 20 in the film hinge 19 forms a kink with the remaining part of the associated number plate, which corresponds to the angle between adjacent number fields of the number carriers 12.
  • the user puts together four number chains from number plates 18, the number sequence in each chain corresponding to the desired sequence of PINs.
  • the chains are then placed around the respectively assigned number carriers 12 and, as can be seen from FIG. 6, closed. Because of the polygonal cross-section of the number carriers 12 that matches the dimensions of the chain links, the chains cannot slip in the circumferential direction.
  • Their axial position on the number carriers 12 is secured by the intermediate rings 14 and in one case by the head part 13, the diameter of the intermediate rings 14 acting in this embodiment at the same time as the knurled edge of the number carriers 12 non-rotatably connected to them being so large that that they protrude a little radially beyond the outer surfaces of the number plates 18.
  • the materials used in other versions of the PIN marker can be metallic or other suitable materials such as minerals, wood or plastics.
