Description

[0001] The invention relates to a locking system for a door or a window and to a door or a window with such a locking system.

[0002] It is known in practice to use handles designed as door handles or window handles to operate a door or window lock. These handles are arranged on the two large surfaces of the door or window and are connected to one another via a polygonal pin, particularly a square pin. The handles are arranged on the polygonal pin in a rotationally fixed manner, so that a synchronous adjustment movement occurs when one of the handles is operated. The polygonal pin engages a lock nut of a mortise lock, which is inserted into a corresponding lock receptacle in a door leaf or window leaf. The lock nut has a polygonal receptacle with which the polygonal pin engages.

[0003] For example, with doors to sanitary rooms, such as bathrooms or toilets, it may be necessary to secure the room in question from the inside, i.e., the door must be lockable from the inside. However, this requirement can also arise analogously for any other rooms and is not limited to the aforementioned types of rooms. A locking system according to the preamble of claim 1 is known, for example, from US 2021 / 238882 A1.

[0004] The invention is based on the object of creating an alternative locking system by means of which a door or window can be locked in its closed position from one side using a polygonal pin. Furthermore, the invention is based on the object of providing a window and a door with such a locking system.

[0005] This object is achieved according to the invention by the locking system having the features of patent claim 1, the door having the features of patent claim 14 and the window having the features of patent claim 15.

[0006] According to the invention, a locking system for a door or window is provided, comprising a first handle, a second handle, a polygonal pin with a base pin, and a locking slide. The polygonal pin engages the first handle at a first end in a rotationally fixed manner and the second handle at a second end opposite the first end in the axial direction of the polygonal pin. The base pin extends continuously between the two handles. The locking slide is mounted on the base pin so that it can move in the axial direction of the polygonal pin. The polygonal pin has an engagement element for engaging a lock follower of a lock. The engagement element is rotatably mounted relative to the base pin and can be switched by means of the locking slide between a holding state, in which the engagement element is arranged so as to be rotationally fixed relative to the base pin, and a release state.In the released state, the engagement element is rotatable relative to the base pin, in particular about a longitudinal axis of the polygonal pin.

[0007] The core idea of ​​the invention is that the engagement element can be switched between the held state and the released state by means of the polygonal pin. In the held state, the engagement element is rotated together with the base pin when one of the two handles is operated, so that the corresponding lock can be operated via the lock nut. In the released state, however, when one of the handles is operated, only the base pin is rotated relative to the lock or the lock nut, while the engagement element remains unrotated, so that the lock nut or the lock is not operated. The latter corresponds to the locked position of the locking system, in which the door or window cannot be opened even if one of the handles is operated.

[0008] The base pin can be made of one or more parts.

[0009] The polygonal pin, for example, is at least partially designed as a square pin.

[0010] In a preferred embodiment, the locking system according to the invention comprises an emergency release slide that can be moved in the axial direction of the polygonal pin. The emergency release slide is arranged on the side of the polygonal pin facing away from the locking slide and can be moved between a basic position and an emergency position.

[0011] In the basic position, the emergency release slide is disengaged from the engagement element, i.e., spaced from it or has no connection to it. Thus, the engagement element can be rotated relative to the base pin, for example.

[0012] If the emergency release slide is in the emergency position, the emergency release slide can engage the engagement element in such a way that the engagement element is held in a rotationally fixed position relative to the base pin. If the emergency release slide is in the emergency position, a rotational movement of the base element can be transmitted to the engagement element. Operating one of the handles can thus activate the lock follower or the corresponding lock, allowing the door or window to be opened.

[0013] The emergency release slide can be mounted on the base pin so that it can be moved.

[0014] In a preferred embodiment of the locking system according to the invention, the base section comprises at least one guide track on which the locking slide or the emergency release slide is displaceably mounted.

[0015] The base section can have exactly two guideways, wherein the locking slide is slidably mounted on a first of the guideways and the emergency release slide is slidably mounted on the second guideway.

[0016] In an exemplary embodiment of the locking system according to the invention, the locking slide and / or the emergency release slide are / is T-shaped.

[0017] The at least one guideway can be delimited laterally by side walls which extend away from a base body of the base pin, in particular in extension of the side walls of the base body.

[0018] For example, the side walls each have a recess.

[0019] Arms of the T-shaped locking slide or the T-shaped emergency release slide can be arranged in the recesses.

[0020] The recesses can be aligned with each other in the transverse direction of the polygonal pin.

[0021] In the axial direction of the polygonal pin, the recesses are, for example, of a length such that the locking slide or the emergency release slide can be moved in the axial direction of the polygonal pin. The length of the recess in the axial direction of the polygonal pin is therefore, for example, greater than the extension of the arms of the T-shaped locking slide or the T-shaped emergency release slide in the axial direction of the polygonal pin.

[0022] By means of the recesses, the relative movement range of the locking slide or the emergency release slide to the base pin can be limited.

[0023] In an exemplary embodiment of the locking system according to the invention, the locking slide is displaced in the holding state in the direction of the engagement element in such a way that the engagement element is arranged, in particular partially, in a groove-like receptacle of the engagement element in such a way that the holding element transmits a rotational movement of the base pin to the engagement element.

[0024] In a preferred embodiment of the locking system according to the invention, the groove-like receptacle of the engagement element is aligned with the at least one guide track, in particular with the guide tracks, when the handles are in an unactuated state.

[0025] In an exemplary embodiment of the locking system according to the invention, the base pin, the engagement element and / or the locking slide are designed as separate components.

[0026] The locking slide and / or the emergency release slide can or can (each) have a longitudinal extension, i.e. an extension in the axial direction of the polygonal pin, which is at most half, in particular less than half, of the longitudinal extension of the base pin.

[0027] In an exemplary embodiment of the locking system according to the invention, the locking slide engages with its end facing away from the engagement element in a shaft of the first handle, on which an actuating element connected, in particular fixedly, to the locking slide is arranged.

[0028] The actuating element can, for example, be screwed to the locking slide.

[0029] By means of the actuating element, the locking slide can be switched between the holding state and the release state, in particular by moving the locking slide in the axial direction of the polygonal pin.

[0030] The actuating element is manually accessible, for example, when the locking system is mounted on a door or window.

[0031] The actuating element can pass through a shaft of the first handle in the radial direction.

[0032] In a preferred embodiment, the locking system according to the invention comprises a folding element pivotally mounted on the emergency release slide. This allows the folding element to pivot between an inserted position and an installed position.

[0033] The folding element can be pivotable about a rotation axis extending in the transverse direction of the polygonal pin.

[0034] For example, the folding element, in particular a longitudinal axis of the folding element, is aligned horizontally in the inserted position, whereas the folding element is aligned vertically in the assembled position. As a result, the slider, together with the folding element, in the inserted position, in which the longitudinal axis of the slider and the longitudinal axis of the folding element are aligned parallel, can be easily pushed through the lock nut to install the actuating device, whereby tilting or wedging of the polygonal pin during assembly of the actuating device can be ruled out. In addition, the vertical alignment of the folding element in the assembled position, in which the locking system is fully mounted on the door or window and in which the longitudinal axis of the folding element is arranged orthogonally to the longitudinal axis of the emergency release slide, allows easy access to the emergency release slide via the folding element.

[0035] In an exemplary embodiment, the locking system according to the invention comprises a spring that preloads the emergency release slide in a home position. Moving the emergency release slide from the home position to the emergency position thus requires a force acting counter to the spring force, particularly in the direction of the engagement element. When the external force is removed, the spring automatically returns the emergency release slide to the home position.

[0036] In an exemplary embodiment of the locking system according to the invention, the second handle, in which the emergency release slide is arranged, comprises at least one tool opening.

[0037] The second handle can have exactly one tool opening or exactly two tool openings.

[0038] A tool, in particular a pin, for moving the emergency release slide, in particular from the basic position to the emergency position, i.e. for moving the emergency release slide in the axial direction of the polygonal pin, can be inserted through the tool opening.

[0039] If the emergency release slide is moved in the direction of the locking slide, for example by means of the tool, i.e. when the emergency release slide is pressed, a rotational movement of the base pin is transmitted via the emergency release slide to the engagement element so that the lock nut can be actuated.

[0040] The tool opening can be formed on an underside of the handle, in particular in the form of an elongated slot, or on a side of the handle facing away from the first handle, in particular in the form of a round recess.

[0041] The tool opening can be arranged so that a tool can be inserted through the tool opening in such a way that the tool rests directly against the emergency release slide.

[0042] The tool opening is arranged, for example, in such a way that a tool can be inserted through the tool opening in such a way that the tool rests against the folding element or engages in a recess of the folding element, which in turn transmits an adjustment movement to the emergency release slide.

[0043] In an exemplary embodiment of the locking system according to the invention, the base pin comprises two polygonal sections, in particular one polygonal section at each end, and a bearing section connecting the two polygonal sections to one another.

[0044] The base pin can be designed in one or two parts.

[0045] For example, one of the polygonal sections and the bearing section is designed as one component and the other polygonal section forms a separate component.

[0046] At least one of the polygonal sections has at least one guideway.

[0047] For example, both polygonal sections each include one of the guideways.

[0048] The polygonal sections can be square sections.

[0049] In a preferred embodiment of the locking system according to the invention, the bearing section has a substantially round cross-section and is tapered compared to the polygonal sections.

[0050] At least one of the polygonal sections can comprise a rectangular base body, from which side walls laterally delimiting the guideway extend in a first region and a second region, so that a U-shaped profile is formed.

[0051] The engagement element has, for example, a U-shaped profile in cross section with a further, in particular rectangular, base body and further side walls.

[0052] The engagement element can have a profile that is closed in cross-section, in particular rectangular or cuboid-shaped.

[0053] The engagement element has, for example, at least one notch on its upper side in which the locking slide or the emergency release slide can be partially arranged.

[0054] The receptacle of the engagement element corresponds to the bearing section, in particular such that the engagement element is rotatable about the axial direction of the polygonal pin, wherein the bearing section prevents movement of the engagement element in the transverse direction and / or vertical direction.

[0055] The further basic body can correspond in its design to the basic body.

[0056] The further side walls can be designed in the same way as the side walls. Furthermore, the invention relates to a door comprising a locking system as described above.

[0057] Furthermore, the invention relates to a window having a locking system as described above.

[0058] Examples of locking systems according to the invention are shown schematically in simplified form in the drawing and are explained in more detail in the following description. It shows: Figure 1 a locking system in an unassembled state; Figure 2 the locking system according to Figure 1 with composite polygonal pin; Figure 3 a perspective view of the locking system Figure 1 together with a door leaf in a locked state; Figure 4 one Figure 3 corresponding view of the locking system with door leaf in the locked state with pressed handles; Figure 5the locking system together with the door leaf in the release state; Figure 6 the locking system according to Figure 5 in the release state with the handles pressed; Figure 7 the locking system together with the door leaf when the emergency release slide is activated; Figure 8 the locking system together with the door leaf with the emergency release slide activated and the handles pressed; Figure 9 a perspective view of another locking system in a non-assembled state together with a door leaf; Figure 10 a polygonal pin, a locking slide, an emergency release slide, a spring and a pin of the further locking system in a single representation in a non-assembled state; Figure 11 one Figure 10 corresponding view in an assembled state; Figure 12 one Figure 11 corresponding view together with a handle and an actuating element of the further locking system in a partially assembled state; Figure 13 one Figure 12 corresponding view in another partially assembled state; Figure 14 one Figure 13 corresponding view together with the door leaf; Figure 15 a sectional view through the further locking system and the door leaf in a further partially assembled state; Figure 16 a sectional view through the further locking system and the door leaf in a further partially assembled state; Figure 17 one Figure 15 corresponding view in an assembled state of the locking system; Figure 18 one Figure 17 corresponding view in an emergency position; Figure 19 a perspective view of a polygonal pin of another locking system in a non-assembled state; Figure 20 one Figure 19 corresponding view in an assembled state; and Figure 21 a sectional view through a polygonal section of the polygonal pin from Figure 19 .

[0059] In the Figures 1 to 8a locking system 10 is shown which is used for installation in a door leaf 12, which is in particular a component of a door of a sanitary room or the like.

[0060] The locking system 10 comprises a first handle 14 and a second handle 16. The handle 14 is arranged on the side of the door leaf 12 facing the sanitary room. The handle 16 is arranged on the outside of the door, i.e., on the side of the door leaf 12 facing away from the respective sanitary room. The handle 14 is rotatably mounted on a first rosette 18, and the handle 16 is rotatably mounted on a second rosette 20. The rosettes 18 and 20 are connected to the door leaf 12 in a rotationally fixed manner.

[0061] The locking system 10 further comprises a multi-part polygonal pin 22 having a base pin 24. The base pin 24 is preferably formed as a single piece and engages with a first end 26 in a rotationally fixed manner in a shaft 28 of the handle 14. A second end 30 of the base pin 24 engages in a rotationally fixed manner in a shaft 32 of the handle 16, which is rotatably mounted on the rosette 20.

[0062] The ends 26 and 30 of the base pin 24 are each formed by polygonal sections which are connected to one another via a rod-like bearing section 34 which has a substantially round cross-section, in particular with a flat upper side, and is tapered relative to the polygonal sections.

[0063] An engagement element 36 is rotatably mounted on the bearing section 34 of the base pin 24, the outer dimensions of which correspond to the dimensions of a receptacle 38 of a lock nut 40 of a mortise lock 42. The mortise lock 42 is arranged in a lock receptacle 44 of the door leaf 12.

[0064] In order to be able to hold the engagement element 36 on the bearing section 34 in a rotationally fixed manner relative to the base pin 24, the polygonal pin 22 has a locking slide 44 which is displaceably mounted in a guide track 46 of the polygonal section of the base pin 24 forming the end 26.

[0065] The locking slide 44 is provided with an actuating element 48 which extends radially through the shaft 28 of the handle 14. By means of the actuating element 48, the locking slide 44 can be manually moved between a door securing position in which it does not engage in a receptacle 50 of the engagement element 36 (see Figures 3 and 4), and a holding position in which it engages in the receptacle 50 of the engagement element 36, so that when one of the handles 14 and / or 16 is actuated, the latter is rotated together with the base pin 24, whereby the lock nut 40 and the lock 42 are actuated (see Figures 5 and 6 ).

[0066] The polygonal pin 22 further comprises an emergency release slide 52, which is displaceably mounted in a guide track 54 of the polygonal section of the base pin 24 forming the end 30 and which is preloaded by a spring 56 into a basic position in which it is disengaged from the engagement element 36. When the emergency release slide 52 is pressed against the force of the spring 56 into the receptacle 50 of the engagement element 36, the engagement element 36 is secured against rotation with respect to the base pin 24, so that actuation of one of the handles 14 and 16 leads to actuation of the lock nut 40.

[0067] In order to be able to actuate the emergency release slide 52, the handle 16 has a tool opening, in particular a tool hole 58, into which a pin-like tool can be inserted and pressed against a bevel 60 of the emergency release slide 52. The emergency release slide 52 can thus be pressed into the engagement element 36 with its end facing away from the bevel 60, so that actuation of the handle 16 leads to actuation of the lock nut 40 (see Figures 7 and 8 )

[0068] When the handles 14 and 16 are not pressed, the guideways 46 and 54 of the polygonal sections of the base pin 24 are aligned with the groove-like receptacle 50 of the engagement element 36.

[0069] The locking slide 44 and the emergency release slide 52 each have stop knobs 62 and 64, respectively, which interact with corresponding counter stops 66 and 68 of the base pin 24 in such a way that they limit a maximum displacement path of the slides 44 and 52.

[0070] In the Figures 9 to 18 a locking system 70 is shown which serves for installation in a door leaf 12, which is in particular a component of a door of a medical room or the like.

[0071] The locking system 70 comprises a first handle 72 and a second handle 74. The first handle 72 is arranged on the side of the door leaf 12 facing the first-aid room. The second handle 74 is arranged on the outside of the door, i.e., on the side of the door leaf 12 facing away from the respective first-aid room. The first handle 72 is rotatably mounted on a first rosette 76, and the second handle 74 is rotatably mounted on a second rosette 78. The rosettes 76 and 78 are in turn connected to the door leaf 12 in a rotationally fixed manner.

[0072] Furthermore, the locking system 70 comprises a polygonal pin 80. The polygonal pin 80 has, as can be seen in particular from Figure 10 As can be seen, it has a base pin 82 and an engagement element 94. The base pin 82 comprises a bearing section 92 and two polygonal sections 126 and 128. The polygonal sections 126 and 128 are connected to one another via the bearing section 92, thus bordering the bearing section 92 at the ends.

[0073] The bearing section 92 has a round outer circumferential surface in a lateral and lower area. On its upper side, the bearing section 92 is flat and aligned with guideways 98 and 106 of the polygonal sections 126 and 128, respectively. The locking slide 96 is rotatable about the longitudinal axis of the polygonal pin 80 on the bearing section 92.

[0074] The polygonal sections 126 and 128 each comprise a base body 132 with a rectangular cross-section and side walls 130. An upper side of the base body 132 forms the guide track 98 or 106. The guide track 98 or 106 is laterally delimited by the side walls 130 in a first partial region and a second partial region. The side walls 130 form upwardly extending extensions of the outer sides of the base body 132 in the vertical direction. Between the first region and the second region, the side walls 130 each have a recess 134.

[0075] The locking system 70 further comprises a locking slide 96, which is mounted on the base pin 82, particularly in the guide track 98, for displacement in the longitudinal direction of the polygonal pin 80. The locking slide 96 is T-shaped, i.e., it comprises a base body extending in the axial direction of the polygonal pin 80, from which arms 136 extend laterally in the transverse direction.

[0076] The arms 136 are in an assembled state, as can be seen particularly from Figure 11 As can be seen, they are arranged in the recesses 134, while the base body of the locking slide 96 rests on the guide track 98. The recesses 134 have a larger dimension in the longitudinal direction of the polygonal pin 80 than the arms 136. This enables and limits the displacement of the locking slide 96 in the guide track 98.

[0077] Furthermore, the locking slide 96 comprises a stop knob 114 which interacts with corresponding counter stops 116 of the base pin 24, so that the maximum displacement path of the locking slide 96 is fixed.

[0078] In order to hold the engagement element 94 on the bearing section 92 in a rotationally fixed manner relative to the base pin 82, the locking slide is displaceable in the axial direction of the polygonal pin 80 in the direction of the engagement element by means of an actuating element 100, which extends radially through the shaft 86 of the first handle 72, such that the locking slide 96 is partially arranged in a receptacle 102 of the engagement element 94. The engagement element 94 is thereby in a holding position in which the engagement element 94 is rotated together with the base pin 82 upon actuation of one of the handles 72 and 74, whereby the lock nut 40 and the lock 42 are actuated and the door can be opened.

[0079] If, however, the locking slide 96 is not arranged in the receptacle 102, the engagement element 94 is in a released state. In the released state, the base pin 82 is rotatable relative to the engagement element 94, so that actuation of the handles 72 and 74 does not cause actuation of the lock follower 40 and the lock 42.

[0080] The locking system 70 further comprises an emergency release slide 104 for emergency unlocking the door from one side on which the second handle 74 is arranged. The emergency release slide 104 is T-shaped, i.e., it comprises arms 136 extending in the transverse direction and a base body extending in the longitudinal direction of the polygonal pin 80. Adjacent to the end of the base body is a bevel 112 that extends downward in the vertical direction.

[0081] A folding element 120 is pivotably mounted on the bevel 112 about a pivot axis extending in the transverse direction. Because the folding element 120 is pivotally connected to the emergency release slide 104, it can be pivoted between an insertion position and an assembly position.

[0082] In the inserted position, the folding element is aligned horizontally, i.e., it extends in the axial direction of the polygonal pin 80. In the assembled position, the folding element 120 is aligned vertically, i.e., vertically. This allows the emergency release slide 104, together with the folding element 120, to be easily pushed through the lock nut 40 for mounting the actuating device in the inserted position, in which the longitudinal axis of the emergency release slide 104 and the longitudinal axis of the folding element 120 are aligned parallel to each other (see Figure 14 ).

[0083] By means of a tool 124, which can be introduced into the second handle 74 through a tool hole 110 of the second handle 74 for moving the folding element 120, the folding element 120 is, as shown in the Figures 15 to 17 is shown, from which in Figure 15 shown insertion position into the assembly position, which is Figure 17 is shown.

[0084] The second handle 74 further comprises a tool slot 122 on an underside of the shaft. The tool 124 can be engaged with the folding element 120 through the tool slot 122, so that the folding element 120 can be displaced in the direction of the door leaf 12. The folding element 120, in turn, transmits the displacement movement to the emergency release slide 104. The emergency release slide 104 is displaced in the direction of the engagement element 94 in the axial direction of the polygonal pin 80 in such a way that a front end of the emergency release slide 104 is arranged in the receptacle 102 of the engagement element 94, whereby the engagement element 94 is in the holding state. An adjustment movement of the emergency release slide 104 relative to the polygonal pin 80 is defined by a geometric configuration of the arms 136 in relation to the recess 134.

[0085] Furthermore, the locking system 70 comprises a spring 108, a pin 118, and a bearing element 138, which is fixed to an underside of the emergency release slide 104. The base pin 82 has a spring receiving space at its end. The spring 108 and an end region of the pin 118 facing the base pin 82 are arranged in the spring receiving space. The bearing element 138 transmits an adjusting movement of the emergency release slide 104 to the pin 118. The pin 118, in turn, compresses the spring 108, thereby tensioning it. When an external force acting on the locking slide 96 is removed, the emergency release slide 104 is thus returned to its initial position due to the tension of the spring 108, in which position the emergency release slide 104 is not arranged in the receptacle 102 of the engagement element 94.

[0086] Furthermore, the further locking system 70 corresponds to that in the Figures 1 to 8locking system 10 shown, which is why reference is made to the above explanations.

[0087] The Figures 19 and 20 show an alternative embodiment of a polygonal pin 140 of a locking system according to the invention. The polygonal pin 140 can be used instead of the polygonal pin 22 or the polygonal pin 80 of the locking system 10 or 70, respectively.

[0088] The polygonal pin 140 is essentially identical in design to the polygonal pins 22 80. Therefore, structurally identical elements are provided with the same reference numerals and the above statements concerning these apply accordingly to the polygonal pin 140. Therefore, only the distinguishing features are explained below.

[0089] As is particularly evident from Figure 19As can be seen, the polygonal pin 140 is formed in several parts. In particular, the polygonal pin 140 comprises a first polygonal pin element 162, a second polygonal pin element, and a third polygonal pin element. The first polygonal pin element 162, the second polygonal pin element, and the third polygonal pin element are designed as separate components. The first polygonal pin element 162, together with the second polygonal pin element, forms a two-part base pin. The first polygonal pin element 162 comprises a first polygonal section 146 and a bearing section 144. In particular, the first polygonal pin element 162 is formed from the first polygonal section 146 and the bearing section 144.

[0090] The first polygonal section 146 corresponds in its design to the polygonal sections 126 of the shooting system 70.

[0091] The bearing section 144 corresponds in its design to the bearing section 92 of the locking system 70, with the exception that the bearing section 144 has a tapered end section 156 at an end facing away from the polygonal section 146. The tapered end section 156 has a round cross-section, i.e., it is rod-shaped.

[0092] The second polygonal pin element is formed from a second polygonal section 148.

[0093] The second polygonal section 148 corresponds in its design to the polygonal section 128 of the locking system 70, with the exception that the second polygonal section 148 has a blind hole 154 at its end facing the first polygonal pin element 162 (see Figure 21 ).

[0094] Furthermore, the second polygonal section 148, analogous to the polygonal section 128, includes a further blind hole 164 for receiving a spring and / or a pin. The further blind hole 164 is arranged on a side of the polygonal section 148 opposite the blind hole 154.

[0095] The third polygonal pin element is an engagement element 150. The engagement element 150 corresponds in its design to the engagement element 94 of the locking system 70, with the exception that the engagement element 150 is closed in the vertical and transverse directions. The engagement element 150 is therefore essentially rectangular.

[0096] A through hole 152 extends through the engagement element 150.

[0097] A first notch 158 and a second notch 160 are provided on a wall of the engagement element 150 that defines the through-hole 152 at the top. The first notch 158 is formed on a side of the upper side of the engagement element 150 facing the first polygonal section 146. The second notch 160 is formed on a side of the upper side of the engagement element 150 opposite the first notch 158, i.e., on a side facing the second polygonal section 148. The first notch 158 and the second notch 160 each have a geometry such that a locking slide or a groove release slide can be arranged therein for locking or releasing the locking system.

[0098] As is particularly evident from Figure 20As can be seen, in an assembled state of the polygonal pin 140, the engagement element 150 is pushed onto the bearing section 144, i.e., the bearing section 144 is arranged in the through-hole 152 of the engagement element 150 such that the engagement element 150 bears against the first polygonal section 146. In this case, side walls 130 of the first polygonal section 146 can adjoin side walls that define the first notch 158, so that a continuous guide track 98 is formed. The notch 158 of the engagement element 150 thus directly adjoins the guide track 98 of the first polygonal section 146.

[0099] When the engagement element 150 is pushed on, the tapered end portion 156 protrudes at least partially, in particular completely, at an end facing the second polygonal portion 148. The engagement element 150 is thus pushed onto the bearing portion in such a way that the tapered end portion 156 protrudes again from the through-hole 152 of the engagement element 150 on the side facing away from the first polygonal portion 146.

[0100] The second polygonal section 148 is pushed onto the tapered end section 156, in particular the protruding region of the tapered end section 156, such that the second notch 160 adjoins a guide track 106 of the polygonal section 148.

[0101] The one in the Figure 19 and Figure 20 The polygonal pin 140 shown differs from the ones shown in the Figures 1 to 18 shown polygonal pins 22 and 80 in particular in that the base pin is designed in two parts and not in one part. List of reference symbols
