Description

Technical field The invention relates to a mechanical device for simultaneously generating at least two different passwords depending on a set password, comprising at least one housing and at least two coding strips arranged longitudinally displaceable on the housing, wherein at least one predetermined series of password characters extending in the longitudinal direction of the respective coding strip is arranged on each coding strip, wherein at least two viewing openings are formed on a front side of the housing through which the generated passwords can be read. State of the art From DE 103 38 955 A1, a mechanical device for simultaneously generating several different passwords depending on a set password is known. This known mechanical device has a housing and four coding strips arranged longitudinally on the housing. On each coding strip, a predetermined sequence of password characters is arranged along the length of the respective coding strip. Several viewing windows are provided on a front side of the housing through which the generated passwords can be read. EP 1 703 484 A2 and DE 691 07 471 T2 also disclose such a mechanical device for simultaneously generating several different passwords depending on a set password. Such a device makes it possible for a person to remember only the password whose setting on the device automatically generates the passwords that can then be read from the device. Disclosure of the invention One object of the invention is to provide a more easily handled mechanical device of the type mentioned above. This problem is solved by the independent patent claim. Advantageous embodiments are described in the dependent patent claims, the following description, and the figures, whereby these embodiments, either individually or in combination with at least two of them, can represent an advantageous and / or further developing aspect of the invention. A mechanical device according to the invention for simultaneously generating at least two different passwords depending on a set password has at least one housing and at least two coding strips arranged longitudinally displaceable on the housing, wherein at least one predetermined series of password characters extending in the longitudinal direction of the respective coding strip is arranged on each coding strip, wherein at least two viewing openings are formed on a front side of the housing through which the generated passwords can be read, and wherein at least one further predetermined series of password characters extending in the longitudinal direction of the respective coding strip is arranged on each coding strip for generating the passwords. With the mechanical device according to the invention, at least two different passwords can be securely generated using a single password. This is achieved by setting the password on the device by shifting the coding strips relative to the housing and to each other. The passwords thus inevitably generated can then be read from the device and used as intended. The mechanical device according to the invention can also be configured to simultaneously generate three or more different passwords depending on the password. In the mechanical device according to the invention, both the initial sequence of password characters and the subsequent sequence of password characters for each coding strip are predefined. A user of the mechanical device according to the invention therefore does not have to laboriously devise the subsequent sequence of password characters and manually apply it to the coding strips, as is necessary for the implementation of the technical teaching described in DE 103 38 955 A1. The user also does not have to consider the types and combinations of password characters for each subsequent sequence and each coding strip before using the device, since these are predefined in the mechanical device according to the invention. Instead, the mechanical device according to the invention can be used directly as intended.It is ready for use and can be operated directly by the user in the desired manner to set the various passwords depending on a password created by the user. The user can therefore freely select the password from the available password characters on the coding strips. The fact that each string of password characters is predefined means that the user of the mechanical device according to the invention does not need to worry about the type, number, combination, and positioning of the password characters for each string before using the device. Similarly, the fact that each subsequent string of password characters is predefined means that the user of the mechanical device according to the invention does not need to worry about the type, number, combination, and positioning of the password characters for each subsequent string before using the device. This greatly simplifies the use of the mechanical device according to the invention, which significantly increases its acceptance among potential customers and users.Such a user acquires precisely this type of device in order to minimize the effort required to generate passwords, which is maximally achievable with the mechanical device according to the invention. The predefined sequence of password characters can be achieved, for example, by printing them onto the respective coding strip or affixing them as a whole. Alternatively, the respective sequence of password characters can be predefined, for example, by embossing, burning, stamping, rolling, or laser engraving them into the respective coding strip. The predefined sequence of password characters can be achieved, for example, by printing them on the respective coding strip or affixing them as a whole. Alternatively, the respective sequence of password characters can be predefined, for example, by being embossed, burned, stamped, rolled, or laser-etched into the respective coding strip. The mechanical device according to the invention can be of various dimensions. For example, the mechanical device according to the invention can be at least the size of a bank card or bank card sleeve. However, in order to generate longer and therefore more secure passwords, the mechanical device according to the invention is preferably larger than a bank card sleeve. The housing can, for example, be flat, with a flat, particularly planar, front and a flat, particularly planar, rear opposite the front. Two or more viewing windows are provided on the front of the housing for reading the passwords set according to the password. The viewing windows can, for example, be arranged in a row, aligned parallel to the direction of movement of the coding strips. At least one viewing window can, for example, be rectangular, elliptical, or elongated. A transparent window element made of glass or plastic can, for example, be arranged at at least one viewing window to protect the interior of the housing from contamination.The casing can be made, for example, partially or completely from a metal, a metal alloy, a plastic, a composite material, cardboard or paper. Each viewing window may have a labeling field that the user can write on to assign a specific purpose to the password displayed in the window. The labeling field may, for example, be located above the viewing window. Alternatively, the viewing windows may be numbered, with at least one labeling field on the housing, similar to a legend, allowing the user to assign a specific purpose to each viewing window number by writing on it. The mechanical device according to the invention can, for example, be offered such that the number of available coding strips is greater than the maximum number of coding strips that can be arranged on the housing. If the housing is designed, for example, to accommodate 14 coding strips, the device can be supplied with, for example, 20 coding strips, from which the user can individually select and arrange 14 coding strips on the housing. The coding strips can differ from one another with regard to the available password characters and / or password symbols, or they can be identical. The former offers greater security and increased variability of the generated passwords. The coding strips can, for example, be designed as flat strips arranged in a plane on the housing. At least one coding strip can be made partially or entirely of a metal, a metal alloy, a plastic, or a composite material. The fact that the respective coding strip is arranged in a longitudinally displaceable manner on the housing means, among other things, that it is slidably mounted parallel to its longitudinal extent. In an advantageous embodiment, the password characters are letters. This allows a word, such as a name or the like, or a statement, such as a saying or the like, to be formed using the password characters, which is easier to remember than combinations of numbers or combinations of letters, numbers, and special characters. The more characters the password contains, the easier it is to remember. The password characters can, for example, all be uppercase or lowercase letters. Alternatively, the password characters can contain at least one hyphen to allow the formation of passwords in the form of word combinations where the words are connected by at least one hyphen. According to a further advantageous embodiment, the password characters are arranged on the front side of each coding strip, and the password characters are arranged on the back side of each coding strip, opposite the front side. This allows the password to be set at the back of the housing, while the passwords can be read from the front of the housing. This has the advantage that an unauthorized third party, who, for example, glances at the front of the device while entering a password read from the device, cannot also perceive the password, thus making the device more secure. In this embodiment, the front side of each coding strip is positioned closer to the front of the housing than the back side of that coding strip, and vice versa. According to a further advantageous embodiment, at least one viewing opening is provided on the rear of the housing opposite the front, through which the set password can be read. The viewing opening can, for example, be located in a central area of ​​the rear of the housing. This prevents unauthorized third parties from easily seeing the set password when the mechanical device is in use, thus making the device more secure. The viewing opening on the rear of the housing can, for example, be rectangular, elliptical, or elongated. According to a further advantageous embodiment, at least one recess is formed on the rear side of the housing opposite the front side, through which the set password can be read. This embodiment can be provided as an alternative to the last-mentioned embodiment, so that there is no viewing opening on the rear side of the housing. The recess can have a depth that corresponds, for example, to the font size of the password characters on the coding strips. The recess can, for example, be designed such that all password characters of a password can be displayed in it. Alternatively, a separate recess can be provided for each coding strip or for a combination of a subgroup of the coding strips. The recess can, for example, be arranged on an upper edge section of the rear side of the housing. According to a further advantageous embodiment, the password characters are arranged in an arbitrary order within the respective subsequent character sequence. This further increases the security of the passwords that can be generated with the device. An arbitrary sequence of password characters is understood to mean a sequence of password characters whose password characters are numbers, letters, and / or special characters that are arranged in an arbitrary or randomly mixed order. According to a further advantageous embodiment, the mechanical device has at least one additional coding strip on which at least one predefined string of password characters for setting the password and a predefined string of manually fillable character fields, also running lengthwise along the additional coding strip, are arranged. A user of the device can insert password characters into the character fields of the predefined string, thus further increasing and personalizing the variety of passwords that can be generated. The presence of the character fields allows for easy and precise labeling of the additional coding strip, ensuring that a password character applied to the coding strip by the user is always sufficiently visible on the device when the password is set.The user can label the character fields of the device, for example, when the respective coding strip has been removed from the housing or is not yet attached to the housing. The sequence of character fields can be predefined, for example, by being printed on the respective coding strip or affixed as a whole. Alternatively, the sequence of character fields can be predefined, for example, by being embossed, burned, stamped, rolled, or laser-etched into the respective coding strip.The device can, for example, have a housing that can accommodate 14 coding strips, wherein 16 coding strips with predefined character sequences of password characters and predefined further character sequences of password characters in the form of uppercase and lowercase letters, one coding strip with a predefined character sequence of password characters and a predefined character sequence of password characters in the form of special characters, one coding strip with a predefined character sequence of password characters and a predefined further character sequence of password characters in the form of numbers, and two additional coding strips with predefined character sequences of password characters and predefined sequences of character fields, which can be arranged on the housing in individual combinations.This ensures that every generated password consists of at least the four necessary parameters: at least one uppercase letter, at least one lowercase letter, at least one special character, and at least one number. However, the use of a corresponding additional encoding strip with a predefined series of character fields is not strictly necessary for the invention. According to a further advantageous embodiment, at least one coding strip is detachably connected to the housing without damage. This means, in particular, that the at least one coding strip is guided freely on the housing so that it can be pulled out of the housing in at least one direction and thus detached from it without damage. This allows the coding strip to be easily exchanged for another coding strip in order to vary the coding properties of the device as needed. Preferably, two or more, for example all, coding strips are detachably connected to the housing in a similarly non-destructive manner, so that the coding strips can also be exchanged among themselves to vary the coding properties of the device as needed.Passwords can thus be changed in a simple way by swapping the coding strips, preferably in such a way that the password does not have to be changed, which is made possible by the fact that the character sequences of the coding strips formed from the password characters are identical. According to a further advantageous embodiment, at least one recess is arranged on a lower edge section of the front of the housing, extending transversely to the direction of movement of the coding strips. Through this recess, a lower end section of at least one coding strip in a lower starting position is visible, wherein the coding strip in the lower starting position is largely or completely located within the housing. The recess can, for example, be configured such that the lower end sections of all coding strips in their lower starting positions are visibly arranged within the recess. Alternatively, a separate recess can be provided for each coding strip or for a combination of a subgroup of coding strips. Thus, when the coding strips are in their lower starting positions, the lower end sections of the coding strips are visibly arranged.The lower end sections of the coding strips can, for example, be numbered consecutively by the user. Alternatively, the lower end sections of the coding strips can be marked by the user with an alphabetical sequence of letters. Both alternatives allow for a specific and predetermined order of the coding strips. This has the advantage, for example, that if the coding strips are accidentally or carelessly removed from the housing, the order of the coding strips can be easily restored. Even if an unauthorized person knows the password, they cannot immediately generate the passwords created by the user without knowing the order of the coding strips chosen by the user.Alternatively to this design, the upper end sections of the coding strips can be marked by the user with a corresponding marking that determines the order of the coding strips, so that no recess is required on the lower edge section of the front of the housing. According to a further advantageous embodiment, at least one hinged flap is pivotally arranged on the housing, allowing the recess to be selectively opened or closed. This allows the recess to be closed to prevent unauthorized persons from viewing the sequence of the coding strips. If necessary, the recess can be opened by pivoting the flap. According to a further advantageous embodiment, at least one edge opening is formed on a lower edge section of the housing, extending transversely to the direction of movement of the coding strips, through which a lower end section of at least one coding strip can be pushed downwards out of the housing. The edge opening can, for example, be configured such that the lower end sections of all coding strips can be pushed downwards out of the housing. Alternatively, a separate edge opening can be provided for each coding strip or for a combination of a subgroup of coding strips. Once the lower end sections of the coding strips have been pushed downwards out of the housing, they are visibly positioned outside the housing. The lower end sections of the coding strips can, for example, be consecutively numbered by the user.Alternatively, the lower end sections of the coding strips can be marked by the user with an alphabetical sequence of letters. Both alternatives allow for a specific and predetermined order of the coding strips. This has the advantage, for example, that if the coding strips are accidentally or carelessly removed from the housing, the order of the coding strips can be easily restored. Even if an unauthorized person knows the password, they cannot immediately generate the passwords created by the user without knowing the order of the coding strips chosen by the user. As an alternative to this design, the upper end sections of the coding strips can be marked by the user with a corresponding label that defines the order of the coding strips, so that no opening is required at the bottom edge of the housing. According to a further advantageous embodiment, at least one recess is formed on an upper edge section of the front and / or rear of the housing, extending transversely to the direction of movement of the coding strips. This recess allows access to the upper end section of at least one coding strip in its lower starting position. The recess can be configured, for example, such that the upper end sections of all coding strips in their lower starting positions can be accessed through the recess. Alternatively, a separate recess can be provided for each coding strip or for a combination of a subgroup of coding strips. The depth of the recess can be, for example, in the range of 6 mm to 10 mm, or 8 mm. The width of the recess can be, for example, in the range of 8 mm to 12 mm, or 10 mm.The recess can, for example, be semicircular. If at least one of the aforementioned edge openings is formed on the lower edge section of the front of the housing, the respective coding strip can also be pressed into a recess on the upper edge section of the front and / or the back of the housing, so that the lower end section of the coding strip protrudes downwards from the housing through the edge opening and is thus visible in order to indicate or determine the sequence of the coding strips described above. According to a further advantageous embodiment, the housing has two housing sections, each with at least two longitudinally displaceable coding strips. The two housing sections are pivotally connected to each other at their edges and about a pivot axis running parallel to the direction of displacement of the coding strips, so that the housing is foldable. In the folded state, the device is space-saving. In the unfolded state, the device can generate longer passwords. For example, seven coding strips can be arranged on each housing section, so that 14-digit passwords can be generated with the device in the unfolded state. According to a further advantageous embodiment, the password characters of at least one coding strip are letters arranged in alphabetical order. Preferably, the password characters of all coding strips are letters, so that passwords in the form of words, names, statements, or the like can be set, which a user can remember more easily than combinations of letters, numbers, and / or special characters. According to a further advantageous embodiment, the password characters of at least one coding strip include uppercase letters, lowercase letters, numbers, and special characters. This allows the device to generate passwords that comply with common password guidelines. The invention is explained below by way of example with reference to the attached figures using a preferred embodiment, wherein the features explained below can represent an advantageous and / or further developing aspect of the invention both individually and in different combinations with one another. Brief description of the characters It shows: Fig. 1 a schematic front view of an embodiment of a mechanical device according to the invention; Fig. 2 a schematic sectional view of the mechanical device shown in Fig. 1; Fig. 3 a schematic rear view of the mechanical device shown in Figs. 1 and 2; and Fig. 4 a schematic sectional view of the mechanical device shown in Fig. 3. Detailed description of the characters In the figures, identical or functionally equivalent components are designated with the same reference numerals. To avoid unnecessary repetition, a detailed description of such components may be omitted below. For better clarity of its structure, the invention is described below by comparing it to Figures 1, 2, 3 to 4. Fig. 1 shows a schematic representation of an embodiment of a mechanical device 1 according to the invention for simultaneously generating two different passwords 2a and 2b depending on a set password 3 shown in Fig. 3. The mechanical device 1 has a flat housing 4 with a front side 5 facing the viewer of Fig. 1 and a rear side 6 facing the viewer of Fig. 3. The front side 5 and the rear side 6 are flat and planar. Furthermore, the mechanical device 1 has seven coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g arranged parallel to each other and longitudinally displaceable on the housing 4. Figure 1 shows only the upper end sections 8 of the coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g. The coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g are shown in their entirety in Figures 2 and 4. The coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g are of identical dimensions, meaning they have the same width, length, and thickness. Each coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g has a predetermined sequence of characters running lengthwise along the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g. These characters consist of password characters 9, printed on the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g and shown in Figures 3 and 4, for setting the password 3. The password characters 9 are uppercase letters. The password characters 9 of each coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g are letters arranged in alphabetical order. Furthermore, each coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g has a further predefined sequence of characters running lengthwise along the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g. These characters consist of password characters 10, shown in Figures 1 and 2, printed on the respective coding strips 7a, 7b, 7c, 7d, 7e, 7f, or 7g, for generating the passwords 2a and 2b. The password characters 10 are printed as uppercase and lowercase letters on coding strips 7a, 7c, 7d, 7e, and 7f. The password characters 10 are printed as numbers on coding strip 7b. The password characters 10 are printed as special characters on coding strip 7g. The password characters 10 are located on the front side 11 of the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g. The password characters 9 are located on the reverse side 12 of the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g, opposite the front side 11.The password characters 10 are arranged in an arbitrary order within the respective further character sequence, as shown in Fig. 2. The coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are connected to the housing 4 in a non-destructive manner and can thus be pulled upwards out of the housing 4 by grasping the respective upper end section 8, so that the sequence of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g can be varied and at least one coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g can be exchanged for a differently designed coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g. The mechanical device 1 can have at least one additional coding strip (not shown) on which at least one predetermined sequence of characters running lengthwise along the additional coding strip, consisting of password characters printed on the additional coding strip for setting the password 3, and a predetermined sequence of manually fillable character fields running lengthwise along the additional coding strip are arranged. One of the existing coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g can be replaced with the additional coding strip if necessary. However, this is not mandatory. On the front 5 of the housing 4 are 14 rectangular viewing windows 13 through which the generated passwords 2a and 2b can be read. Each password 2a and 2b is formed from a combination of password characters 10, generated depending on the set password 3. Seven viewing windows 13 are arranged in a row for each password 2a and 2b. The upper row of viewing windows shows password 2a with the content "A1bhTV!", while the lower row of viewing windows shows password 2b with the content "u4nGLs9". On the rear side 6 of the housing 4, seven rectangular viewing windows 14 are arranged in a row, through which the set password 3 can be read. Alternatively, instead of the viewing window 14, at least one edge recess (not shown) can be formed on the rear side 6 of the housing 4, through which the set password 3 can be read. The recess can, for example, be located on an upper edge section of the rear side 6 of the housing 4. The two rows of seven viewing openings 13 each on the front 5 of the housing 4 can, for example, be numbered. Below the viewing openings 13, on the front 5 of the housing 4, there can be a labeling field (not shown) that can serve as a legend to assign functions or purposes to the individual numbers of the rows formed by the viewing openings 13. This can be done, for example, by manually labeling the labeling field by entering the function or purpose next to the respective viewing opening row number. A lower edge section 15 of the housing 4, extending transversely to the direction of movement of the coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g, has a marginal opening 16, schematically indicated by a dashed line. A lower end section 18 of each coding strip 7a, 7b, 7c, 7d, 7e, 7f, and 7g, as shown in Figures 2 and 4, can be pushed downwards out of the housing 4 through this opening. A continuous numbering system (not shown) can then be applied to the lower end sections 18 of the coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g, which have been pushed downwards out of the housing 4, in order to establish the sequence of the coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g. Alternatively, at least one recess (not shown) can be arranged on the lower edge section of the front surface 5 of the housing 4, which runs transversely to the direction of movement of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g, through which the lower end section 18 of each coding strip 7a, 7b, 7c, 7d, 7e, 7f and 7g in a lower initial position shown in Figs. 1, 2, 3 to 4 is visible, wherein the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g is largely located in the housing 4 in the lower initial position. In this case, a flap (not shown) can additionally be pivotably arranged on the housing 4, with which the recess can be selectively opened or closed. Seven approximately semicircular recesses 17 are formed on an upper edge section of the front 5 and the rear 6 of the housing 4, running transversely to the direction of movement of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g. The upper end section 8 of the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g, in its lower starting position, can be accessed through these recesses. The respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g can be pressed into the respective recess 17 and thereby moved downwards, so that the lower end section 18 of this coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g emerges downwards from the housing 4 through the opening 16 at the edge. In one embodiment, the housing 4 can have two housing sections not shown, each of which can be designed according to the embodiment shown in Figs. 1, 2, 3 to 4, wherein the two housing sections can be pivotably connected to each other at their edges and about a pivot axis not shown running parallel to the direction of displacement of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g, so that the housing 4 is designed to be foldable. Fig. 2 shows a schematic sectional view of the mechanical device 1 shown in Fig. 1. In the representation shown in Fig. 2, the front side 5 of the housing 4 is omitted, so that the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are exposed. The character sets consisting of password characters 10 of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are shown in full. In addition, the lower end sections 18 of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are shown, which can be moved downwards out of the housing 4 by shifting the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g downwards. Fig. 3 shows a schematic rear view of the mechanical device 1 shown in Figs. 1 and 2. In this state of the mechanical device 1, all coding strips 7a, 7b, 7c, 7d, 7e, 7f, and 7g are arranged in their lower starting positions, so that the password 3 AAAAAAA appears in the viewing openings 14, which is of course not secure. A desired password 3 can be set by moving the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f, or 7g upwards. Fig. 4 shows a schematic sectional view of the mechanical device 1 shown in Fig. 3. In the representation shown in Fig. 4, the back side 6 of the housing 4 is omitted, so that the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are exposed. The character sets from password character 9 of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are shown in full. In addition, the lower end sections 18 of the coding strips 7a, 7b, 7c, 7d, 7e, 7f and 7g are shown, which can be moved downwards out of the housing 4 by shifting the respective coding strip 7a, 7b, 7c, 7d, 7e, 7f or 7g downwards.
