[0003] The invention further relates to a method for manufacturing a key as described herein according to claim 21. TECHNOLOGICAL BACKGROUND

[0004] Multifunctional tools are now widespread. The more functions a tool is meant to cover, the larger, and therefore more unwieldy, it becomes. This is where the invention comes in. A control cabinet key according to the preamble of claim 1 is already known from US 10,780,555 B2. PRESENTATION OF THE INVENTION

[0005] The invention is based on the objective of improving the handling of multifunctional tools with numerous tool functions. This objective is achieved by a control cabinet key according to claim 1. Further embodiments of the invention are the subject of the dependent claims. Accordingly, the key is provided that the key element of the first and / or the second key arm is arranged in an angled region of the respective key arm, and / or that the key element of the first and / or the second key arm comprises at least one angled region or is formed from at least one angled region. If the key comprises two arms, the key arm angle can be in an angular range of approximately 90° to approximately 270°; in particular, the key arm angle can be approximately 90°, approximately 120°, approximately 180°, or any other angle.

[0006] It may be provided that the angled section is angled about at least one axis extending perpendicular or nearly perpendicular to the longitudinal direction of the key arm on which the angled section is arranged, and / or that the angled section is angled about at least one axis extending parallel or nearly parallel to the longitudinal direction of the key arm on which the angled section is arranged. Multiple angled sections may also be provided, for example, such that a first angled section is formed about a first axis and a first angle with a first angled section, and at least one further angled section is formed about a further axis and a further angle with a further angled section.

[0007] The key element of the second key arm can be arranged in an angled section of the second key arm. The key element of the first key arm can be arranged without an angled section as an end-mounted U-shaped element with stable, particularly flat, legs, wherein the U-shaped key element of the first key arm is suitable for actuating a double-bitted locking device known per se. In this respect, the end-mounted key element of the first key arm, arranged without an angle, is formed as a "U" or as a fork with two prongs. The geometry of the key element of the first key arm can optionally also approximate a (flat, highly simplified) crown. The "U", fork, or crown shape ensures, on the one hand, high stability of the key element when actuating the double-bitted locking device known per se.Secondly, the key element is very compact compared to the conventional double beard, as it is essentially flat. Furthermore, it is relatively easy to manufacture, since it is stamped or cut from a sheet of metal and does not require die casting, as is usually the case with the conventional double beard.

[0008] The key becomes particularly handy and easy to handle if each key arm is at least partially flat. Preferably, each key arm has a rectangular or nearly rectangular cross-section, with the narrow sides of the cross-sectional area being significantly shorter than the long sides.

[0009] For effective handling, it has proven advantageous if the angled section is bent at an angle of 90° or nearly 90° relative to the key arm, preferably by bending the end of the key arm. The angled section protrudes from the plane of the key arm. To minimize the manufacturing effort of the key, it is advantageous if at least one key arm is made from a bent sheet metal part. An opening, particularly a slot-shaped one, can be arranged in or on the angled section of the key arm.

[0010] According to a preferred embodiment, it can be provided that a first angled area arranged on one side, in particular the narrow side, of the key arm is angled by an angle of +120° or nearly +120°, and that a second angled area arranged on the opposite side, in particular the narrow side, of the key arm is angled by an angle of -120° or nearly -120°, whereby, in particular, a key element with a hollow cross-sectional profile with a geometry of an isosceles triangle is formed, with which a lock with corresponding triangular geometry can be actuated, and in which, preferably, a bit, in particular a double bit, can be removably arranged.

[0011] A first angled section arranged on one side, particularly the narrow side, of the key arm can be angled – alternatively or cumulatively – at least by an angle of +90° or nearly +90°. A second angled section arranged on the opposite side, particularly the narrow side, of the key arm can be angled at least by an angle of -90° or nearly -90°, wherein the first and / or the second angled section comprises at least one multiple angle, and wherein the free ends of the angled sections adjoin each other, thereby forming, in particular, a key element with a hollow cross-sectional profile having a square geometry, with which a lock with a corresponding square geometry can be operated.

[0012] A stabilizing element can be provided at adjacent free ends of the angled sections to prevent the angled sections from bending or spreading apart when a closure is (forcefully) operated. The stabilizing element can comprise a material-bonded connection, such as a weld or a spot weld.

[0013] According to a preferred embodiment, a third key arm can be provided, in particular a third and further key arms. The third key arm, in particular the third and further key arms, are arranged in the plane of the key arms. The key arm angle is formed between each adjacent key arm. If three key arms are provided, the angle is approximately 120°, with four arms approximately 90°, with five arms approximately 72°, with six arms approximately 60°, and with n arms 360° / n, where n is a natural number greater than 6.

[0014] It can be advantageous for the third key arm, and in particular the third and subsequent key arms, to be arranged in the plane of the key arms, with a first key arm angle formed between at least two adjacent key arms and a second key arm angle, differing from the first, formed between another key arm and its adjacent key arm. If the key comprises five key arms, the first key arm angle can, for example, be approximately 100° and the second key arm angle can be approximately 65°. Any number of alternatives and angle combinations are possible.

[0015] Preferably, all angled areas are arranged on one side of the key arm plane. It can also be advantageous if at least one angled area is arranged on the opposite side of the key arm plane.

[0016] To operate locking devices, such as those used in electrical cabinets, at least one key element comprises at least one recess whose geometry corresponds to that of the locking device. Locking devices exist with triangular, square, or other geometries. Therefore, it is advantageous if the geometry of the recess in the key element is triangular, square, or polygonal, so that the key element can operate a locking device with a triangular, square, or similar shape.

[0017] The key becomes particularly efficient in terms of manufacturing effort and handling when the geometry of one of the recesses consists of a first square and a second square, rotated at an angle of 45° to the first and positioned above it. This second square can be larger or smaller than the first. For example, each key element can operate a first square lock and a second (larger or smaller) square lock. Alternatively, the geometry of one of the recesses can consist of a first square and a triangle (especially an equilateral triangle) positioned above it. A crescent-shaped recess is also possible. This allows multiple locks to be operated per key element; for example, one key element can operate both a square lock and a triangular lock.Alternatively, the geometry of one of the recesses can be formed by a first, in particular equilateral, triangle and a second triangle rotated by an angle of 60° relative to the first triangle, where the second triangle is larger or smaller than the first triangle. Thus, for example, a first triangular locking mechanism and a second (larger or smaller) triangular locking mechanism can be operated per key element.

[0018] According to an advantageous embodiment, at least one additional key element and / or a bit receptacle is provided. The bit receptacle and / or additional key element can be arranged in or on the key body. The additional key element can, for example, be designed as a bottle opener.

[0019] The additional key element and / or the bit receptacle may be formed by at least one bent section of the flat sheet metal of the key arm. The bent section may have a bend angle of approximately 180°. A (square or rectangular) recess may be provided in the bent section of the additional key element, which can be inserted into or placed onto a (square) counterpart. This forms a key, for example, for a (radiator) valve.

[0020] The key body and / or the key arms can comprise or be made of metal or a metal alloy and / or plastic. Preferably, the key body and the key arms are made of metal or a metal alloy, and a plastic insert or housing is provided, which is arranged in or on the key body. The insert or housing can be customized with color, lettering, markings, or other features, such as an image or logo.

[0021] In a further embodiment, a retaining device with a retractable mechanism can be attached to the key, for example, at an eyelet or through a hole. The retaining device can be attached to the user's clothing, bag, or case. To operate the key, a cord or strap of the retractable mechanism is unwound or pulled out, with the key attached to the end of the cord / strap. After the key is operated, the retractable mechanism, using spring action, retracts the cord or strap, and the key hangs directly from the retaining device.

[0022] The handling of multifunctional tools with numerous functions can also be improved with a multi-part key assembly according to claim 16. The key assembly comprises a first key and at least one second key. The first key and / or the second key is / are formed from a control cabinet key described herein, wherein the key elements of the first key differ from those of the second key. The key assembly forms a compact key, wherein the first and second keys can be separated from each other, so that the first and second keys can be operated independently. The first and second keys can also be movable relative to each other, for example, rotatable, which improves the handling of the key assembly.

[0023] Preferably, the key assembly includes a joint for rotating the first key relative to the second key. By rotating the keys relative to each other, the positions of the key elements can be changed. For example, a key element on a short arm of one key can be positioned by rotating the key so that an adjacent key element on the other key does not interfere with or obstruct the operation of the key element on the short arm. The rotation of the first (second) key relative to the second (first) key can be 360° or more. However, a limiting mechanism can also be provided, restricting the rotation to an angle of less than 360°.At least one of the keys can be provided with a locking device so that the keys can assume at least one, preferably several, locking positions when the two keys are turned.

[0024] The joint arrangement can be designed such that the first and second keys are permanently and irretrievably connected. The fixed rotary connection can include a crimped (connecting) sleeve. Alternatively, an arrangement can be provided in which the first and second keys can be separated and then reconnected. For this purpose, it may be advantageous if the key assembly includes a connecting element for the releasable connection of the first key to the second key. The user can separate the first key from the second key as needed, and after use, the keys can be reconnected. The connection can be made with a plug-in or clip-on connection, or with a twist-and-plug connection (bayonet-like).

[0025] The connecting element preferably comprises a pin arranged on the first or second key, in particular with a collar, and a pin receptacle arranged on the second or first key, in particular with a recess for the pin and / or collar. The connecting element, in particular the collar and pin, can be designed such that the first and second keys can only be separated / joined at a specific angular position. This reduces the probability of the keys being unintentionally separated.

[0026] An offset, particularly an angular offset, can be formed or created between the first and second keys of the key assembly, for example, by means of a hinge. This (angular) offset allows the key elements of the first (second) key to be positioned or arranged in the spaces between the key elements of the second (first) key. This makes the key assembly more versatile in its operation, further improving handling.

[0027] In a compact and easily manageable design of the key assembly, the key arms of the first key can be arranged in a first key arm plane, and the key arms of the second key in a second key arm plane that is parallel to and preferably spaced apart from the first key arm plane. In this respect, the assembly can consist of an upper and a lower key, or of a right and a left key.

[0028] The angled sections can be located on one side of the key arm plane of the first or second key. At least one angled section can be located on the opposite side of the key arm plane of the first or second key.

[0029] According to an advantageous embodiment, at least one inclined surface is provided on a narrow side of a key body and between two adjacent key arms. This inclined surface, together with, in particular, angled bowl elements of these two adjacent key arms, forms a cap lifter for lifting / opening caps and / or crown caps. The area of ​​the cap lifter between the key elements is narrower than an adjacent area between the key arms, allowing the cap or crown cap to be partially enclosed by the key elements. The inclined surface is positioned below the edge of the cap or crown cap and forms the opening edge of the cap lifter. The key arms act as levers, so that by moving the key upwards, i.e., away from the bottom of the bottle, the crown cap or cap can be removed from the bottle.

[0030] An improvement in the handling of multifunctional tools with many tool functions can also be achieved with a method according to claim 21. The method is used to manufacture a key described herein. The key arms are cut and / or punched and / or sawed and / or milled from a sheet of metal. Openings or recesses are cut or punched out. The angled section of at least one key arm, in particular of several or all key arms, is formed by bending the end and / or edge of the key arm.

[0031] Before bending the key arm, an opening, particularly a slot, can be arranged in, on, or immediately adjacent to the angled area. This effectively reduces the amount of key arm material that needs to be bent. The (slot-shaped) opening can project into the recess of the key element, or the recess of the key element can project into the (slot-shaped) opening.

[0032] The recess and (slot-shaped) opening can be connected in such a way that the recess encompasses the (slot-shaped) opening. This allows the key element to be made more compact, as the counterpart of the lock or the tool can penetrate the respective recess of the key element more easily and securely. Furthermore, this prevents the counterpart of the lock from "butting" against the end face of the key arm, which would otherwise hinder the combination of the key and its counterpart.

[0033] The aforementioned components, as well as those claimed and described in the exemplary embodiments, to be used according to the invention are not subject to any special exceptional conditions with regard to their size, shape, material selection and technical conception, so that the selection criteria known in the field of application can be applied without restriction.

[0034] Further details, features, and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following description and the accompanying drawing, in which—by way of example—an embodiment of a key and a key assembly is shown. Individual features of the claims or embodiments can also be combined with other features of other claims and embodiments. BRIEF DESCRIPTION OF THE FIGURES

[0035] The drawing shows Fig. 1A - Your key in different views, Fig. 2A - A key assembly in different views, Fig. 3A - Variants of a key in perspective view, Fig. 4A - Variants of a key assembly comprising a first and second key in different views, Fig. 5A - Another variant of a key assembly in different views, and Fig. 6A - Another variant of a key assembly in different views. DETAILED DESCRIPTION OF EXAMPLES OF EXECUTION

[0036] A key 100, especially a switch cabinet key, can be viewed from a perspective perspective according to Fig. 1A can be removed. The key 100 comprises a key body 50, on which five key arms 1, 2, 3, 4, 5 are arranged. Each of the five key arms 1, 2, 3, 4, 5 is arranged in the plane of the key arm. According to the in Fig. 1B In the top view of key 100 shown, the plane of the key arms is formed by the plane of the drawing. The key arms 1, 2, 3, 4, 5 are evenly distributed in the plane of the key arms, i.e., a key arm angle α of approximately 72° is formed between any two adjacent key arms (1, 2, 3, 4, 5). The key arms 1, 2, 3, 4, 5 are flat, have a rectangular or nearly rectangular cross-section, and their extent (narrow side 12) perpendicular to the plane of the key arms is smaller than their lengths and widths lying in the plane of the key arms.

[0037] The key elements 9 of the key 100 are arranged at the ends of each key arm 1, 2, 3, 4, 5. The key arms 2, 3, 4, and 5 have an angled region 8 at their ends, in or on which the key elements 9 are arranged. The angled regions 8 of the key arms 2, 3, 4, and 5 are each angled at approximately 90°, such that the angled regions 8 according to Fig. 1A project unilaterally out of the plane of the key arm in a common direction. According to the lateral views... Figuren 1C and 1D It can be deduced that the angled areas 8 each protrude upwards from the key arm plane and are perpendicular to the key arm plane.

[0038] The first key arm 1 of the key 100 does not include an angled section. The key element 9 of the first key arm 1 is U-shaped or formed as a crown 16, so that a double-bitted locking mechanism known per se can be operated with it.

[0039] Key body 50 and key arms 1, 2, 3, 4, 5, as well as the key elements 9, are formed from a sheet of metal. The key elements 9 comprise one or more recesses, cutouts 10, or openings formed by cutting or punching the sheet. By bending the end sections of the key arms 2, 3, 4, and 5, the angled section 8 of each of the key arms 2, 3, 4, and 5 is created. To prevent the key elements 9, in particular their recesses 10, from changing (geometrically) when the sheet is bent, each key arm 2, 3, 4, and 5 comprises a slot-shaped opening 26 in, on, or next to the angled section 8.

[0040] An additional key element 20 is arranged in the key body 50, which according to the Figuren 1A and 1BThe key is designed as a bottle opener, i.e., as a tool for removing crown caps from (beverage) bottles. The key body 50 and the key arms 1, 2, 3, 4, 5 are made of metal. The key body 50 comprises a (multi-part) plastic sleeve 51 or a (multi-part) plastic insert 51, which may be colored or have a colored and geometric design. The plastic sleeve 51 or the plastic housing 51 improves the grip of the key 100.

[0041] The Figuren 2A bis 2E Various views of a multi-part key assembly 200 can be taken from the diagrams. The key assembly 200 comprises a first key 100 and a second key 100'. Each key 100, 100' comprises several (here: five each) key arms 1, 1', 2, 2', 3, 3', 4, 4', 5, 5'. A key element 9 is arranged at the end of each key arm 1, 1', 2, 2', 3, 3', 4, 4', 5, 5'. Each key element 9 of a key arm 1, 1', 2, 2', 3, 3', 4, 4', 5, 5' differs from the other key elements 9. The key elements of key arms 1', 2, 2', 3, 3', 4, 4', 5, 5' are each arranged in an angled region 8. The key element 9 of the first key arm 1 of the first key 100 is U-shaped (crown 16) and there is no angled end region of the first key arm 1. The angled end of key arms 1', 2, 2', 3, 3', 4, 4' and 5 is oriented upwards, i.e.It stands on the character level according to the one in . Fig. 2C The top view shown is perpendicular. The angled section of the key arm 5' of the second key 100' is located on the other side of the key arm plane, i.e., it dips into the drawing plane according to Fig. 2C inside.

[0042] In perspective representation according to Fig. 2B The first and second keys 100, 100' have an angular offset. The second key 100' was rotated relative to the first key 100 by the angle α / 2, i.e., by approximately 36°, around the common axis of symmetry of the key bodies 50, 50' via the joint 52. If a detachable connection / separation of the assembly 200 or of the keys 100, 100' from each other is intended, this can be achieved in accordance with Fig. 2B The key arrangement shown will be carried out as follows. When arranged according to Fig. 2A The keys 100 and 100' are captive connected to each other. In the arrangement of the compound 200 according to... Fig. 2B Where keys 100, 100' are twisted relative to each other, the first and second keys 100, 100' can be separated, allowing the user to operate either the first or the second key 100, 100'. A side view of the arrangement according to Fig. 2B can the Fig. 2E can be taken.

[0043] In the design according to the Figuren 2A bis 2E In the center of the key body 50, 50', an additional key element 20 is provided, which includes a bit receptacle 23. A connecting means for connecting / disconnecting the keys 100, 100' can be provided in or on the additional key element 20.

[0044] As in Fig. 2A As can be seen, the key body 50 of the first key 100 includes a holding means 22, with which a chain or a wire loop or another means for holding a tool (bit) can be arranged on the key assembly 200, or with which holding or hanging or connecting the key assembly 200 to another object is achieved.

[0045] The Figuren 3A bis 3D Perspective views of key variants 100 are shown, each of which is formed from sheet metal bending parts or at least includes a sheet metal bending part. According to Fig. 3A The key body 50 is flat and includes an off-center retaining element 22. According to Fig. 3B The key body 50 includes a plastic insert 51, which can be inscribed or customized, for example with an image, logo, etc. In the variant according to Fig. 3C At least one of the key arms (here: arm 3) is longer x in the longitudinal direction of the key arm than the other arms (1, 2, 4, 5). It is possible for the key arms 1, 2, 3, 4 and / or 5 to have different lengths. In the variant according to Fig. 3D Six key arms are provided (1, 2, 3, 4, 5, 6), with a key arm angle α of approximately 60° between each pair of adjacent key arms (1, 2, 3, 4, 5, 6).

[0046] One variant of a 200-key combination is in the Figuren 4A bis 4G shown in various (perspective and detail) views. A side perspective view of the key assembly 200 is shown in Fig 4A The key combination 200 comprises a first and a second key 100, 100'. The second key 100' is shown in the view according to Fig. 4A arranged under the first key 100.

[0047] The two keys 100, 100' are connected to each other by the connecting element 63 in such a way that they are permanently and detachably connected in the arrangement shown. By rotating the first key 100 relative to the second key 100', the first key 100 can be separated from the second key 100'. The key elements 9, 9' of the first key 100 and those of the second key 100' can thus be operated separately. After the keys 100, 100' have been separated and the respective key elements 9, 9' have been operated, the keys 100 and 100' can be rejoined and connected to each other by the connecting element 63. The connecting element 63 includes a pin 65 arranged on the second key 100'. The pin 65 engages in a pin receptacle 67, which is arranged in the first key 100.The pin is essentially rectangular and comprises a collar 66 on each of its two opposite, longer narrow sides. The recess 68 of the pin receptacle 67 is geometrically adapted to the shape or projection of the pin 65. By rotating the pin 65, i.e., by (counterclockwise) rotating the second key 100' relative to the first key 100, the pin 65 rests against the key body 50 of the first key 100, in particular clamping, and an unintentional separation of the two keys 100, 100' is prevented. For this purpose, the pin receptacle 67 may include a chamfer that exerts a clamping force on or against the pin 65. The two collars 66 ensure that the two keys 100, 100' can only be joined in a defined, predetermined orientation or alignment / positioning of the two keys 100, 100'.This prevents the two keys 100, 100' from being assembled in a way in which the angled key elements (9) collide or jam against each other.

[0048] A view from below of the arrangement according to Fig. 4A can the Fig. 4B can be extracted and the Fig 4C shows a supervisor. According to Fig. 4C It is very easy to see that the pin receptacle 67 consists of a round bore with eccentric and geometrically different recesses into which the protruding pin areas of the pin 65 can engage when the keys 100, 100' are in the correct position relative to each other.

[0049] The representations according to the Figuren 4A bis 4E Figure 1 reveals the structure of the special key element 9', which is arranged on one of the key arms (2, 3, 4, 5). The angled sections 8' are angled about an axis p running parallel or nearly parallel to the longitudinal direction of the key arm (2, 3, 4, 5) on which the angled sections 8' are arranged. A first angled section 8', arranged on one narrow side of the key arm (2, 3, 4, 5), is angled at an angle of +120° or nearly +120°, and a second angled section 8', arranged on the opposite narrow side 12 of the key arm (2, 3, 4, 5), is angled at an angle of -120° or nearly -120°. This results in the key element 9' being formed with a hollow cross-sectional profile having an isosceles triangle geometry, with which a closure with corresponding triangular geometry can be operated.This is achieved in particular by manufacturing the key arms (2, 3, 4, 5) and the key (body) blanks (50, 50') from a bendable sheet metal material. This allows sheet metal sections to be bent with minimal equipment, enabling the key geometries and functions to be implemented quickly and easily with minimal tooling, possibly taking into account necessary cutouts or recesses. A particular additional advantage is that – primarily due to the bending according to the invention and the resulting key element geometry – a common bit 62, especially a common double bit, can be arranged in a removable manner. This results in two functions for the key element 9': firstly, locking according to a triangular locking geometry, and secondly, receiving the (double) bit. Side views of the key assembly arrangement according to the... Figuren 4A bis 4C can the Figuren 4D and 4F can be extracted. In particular the Fig. 4F The geometry of the key element 9' can be determined, which is characterized by the fact that two lateral, mutually directed bends in the area of ​​the key arm sides form a triangular key element 9', in the cavity of which the aforementioned bit receptacle (23) is arranged centrally. A (double) bit 62 is seated in the bit receptacle (23), as can be seen from the side view according to Fig. 4E visible.

[0050] The Figuren 4F and 4G Each key shows 100 ( Fig. 4F ) and 100' ( Fig. 4G ). In this respect, a comparison of the Figuren 4F and 4G the key combination arrangement according to the Figuren 4A bis 4E , wherein the keys 100 and 100' forming the key group 200 are in the Figuren 4F and 4G are each separate. The production of the variant of the additional key element 20 according to the Figuren 4A bis 4G can be seen from the representation according to Fig. 4F The following can be traced: A section of the flat key arm (2, 3, 4, 5) with a recess (10) between the lateral narrow sides 12 is bent by approximately 180° towards the key body 50, whereby the additional key element 20 is formed, at least partially, from a double sheet. The bending of the key arm section forming the additional key element 20 is carried out such that all key elements 9 of the key 100 are in accordance with Fig 4F on a common (according to Fig. 4F are located on the upper side of the key arm plane.

[0051] The key 100' of the key assembly arrangement according to the Figuren 4A bis 4E can the Fig. 4G can be extracted. Based on the Fig. 4G The geometry of both the key element 9' and the connecting element 63 can be traced. Regarding the key according to Fig. 4G Some key elements 9 are bent so that they are located on the upper side of the key arm plane, and at least one key element 9 is bent so that it is located on the lower side of the key arm plane. One key element (16) is located so that it lies in the key arm plane.

The first key 100 includes several bores 72 or recesses in its key body into which one or more cams 75 of the second key 100' engage for the purpose of locking when the keys 100, 100' are rotated relative to each other.

[0057] The joint 52 includes a connecting element 63, by which the first and second keys 100, 100' are detachably connected to each other. The connecting element 63 comprises an (asymmetrical) pin 65 arranged on the second key 100' and a pin receptacle 67 arranged in the first key 100, the receptacle having an opening matching the geometry of the pin 65. In a specific angular position of the first and second keys 100, 100', the two keys 100, 100' can be separated from each other, as shown in the exploded view according to [reference to figure]. Fig. 6F as shown. In this position, the separate keys 100, 100' can also be joined together again, and by twisting the joined keys 100, 100' they can be locked in the key assembly 200.

[0058] Key elements 9, 9', such as the U-shaped element 16 for operating a double-bitted lock, require a certain penetration depth in the lock. To prevent other key elements 9, 9' from interfering with or impeding penetration into the lock, the keys 100, 100' can either be separated from each other ( Fig. 6F ), or the keys 100, 100' can be rotated relative to each other in such a way that the key element 16 in question is not affected by any further element 9, 9' in its vicinity.

[0059] Supervision of the key network 200 according to Fig. 6A / B is in Fig. 6D depicted. Fig. 6C shows a view from below. A side view is in Fig. 6E to be seen. According to the exploded view. Fig. 6FThe geometry of the connecting element 63, in particular of the pin 65 and the pin receptacle 67, can be determined. The pin 65 and pin receptacle 67 have at least a taper or at least a recess on one side, so that the pin 65 and receptacle 67 can only be arranged in or against each other in a corresponding position. After connecting the two keys 100, 100', they can be rotated relative to each other about the pin axis, thereby simultaneously locking the two keys 100, 100' in place. REFERENCE MARK LIST
