HINGE ASSEMBLY FOR SWIVEL MOUNTING OF DOORS OR WINDOWS

Description

[0001] The invention relates to a concealed hinge assembly for fastening door or window leaves to a door or window frame so that they can rotate about a hinge axis. The hinge assembly comprises a housing and a cassette partially arranged in an interior of the housing. A hinge bracket is inserted into a receiving area of ​​the cassette along a horizontal direction orthogonal to the hinge axis. Furthermore, the invention relates to a method for adjusting a hinge assembly.

[0002] Such hinge assemblies are known from the prior art and serve to pivotally mount the door or window sash on a door or window frame. Hinge assemblies typically comprise a sash-side hinge plate and a frame-side hinge bracket, which is pivotally mounted in a frame-side mount of the hinge assembly around the hinge axis. To enhance the aesthetic effect and optimize the use of available space, parts of the hinge assembly, in particular the frame-side mount and the hinge axis, can be arranged in a recess in the frame. These are referred to by those skilled in the art as concealed hinge assemblies.

[0003] Typically, the hinge bracket is firmly connected to the sash, for example, by screwing. The hinge bracket is in turn connected to the hinge bracket. Connecting the hinge bracket to a cassette of the hinge bracket is known in the art. The cassette is adjustably connected to parts of the hinge bracket that are firmly attached to the sash. This makes it possible to align the hinge assembly for accommodating the door or window sash along a vertical direction parallel to the hinge axis and along a horizontal direction orthogonal to the vertical direction.

[0004] To correctly adjust the door or window sash, it is necessary to adjust it along all three spatial directions. This requires adjustment of the cassette along the horizontal direction, in other words in a direction orthogonal to the hinge axis and, when the window or door is closed, along the main extension direction of the door or window leaf. Furthermore, adjustment of the cassette along the vertical direction, in other words along the hinge axis, is required. In addition to adjustment in the horizontal direction and adjustment in the vertical direction, adjustment of the hinge arrangement along a seal pressure direction must be provided. The seal pressure direction within the meaning of the present invention is arranged orthogonal to the horizontal direction and orthogonal to the vertical direction.

[0005] Adjusting the door or window sash along the seal pressure direction causes the door or window sash to shift toward or away from a seal on the door or window frame when the door or window is closed. It is known from the prior art to move the frame-side mount of the hinge assembly along the seal pressure direction to adjust the seal pressure direction, which can be very complex. US 9416 573 B2 discloses an example of a hinge assembly.

[0006] The invention is based on the object of providing a band arrangement in which a comfortable and simple adjustment along the sealing pressure direction is possible.

[0007] This object is achieved by the band arrangement set out in claim 1.

[0008] The concealed hinge assembly according to the invention comprises a screw and a threaded pin for adjusting the hinge bracket in a direction orthogonal to the hinge axis and orthogonal to the horizontal direction of the seal. The screw is arranged in a first through-hole of a fastening area of ​​the cassette and in a first threaded hole of the hinge bracket. In other words, the first through-hole and the first threaded hole are aligned along a first screw-in direction of the screw.

[0009] A screw head of the screw is arranged so as to bear against a contact surface of the fastening area facing away from the hinge bracket. In particular, it is provided that a lower surface of the screw head bears against the contact surface. Furthermore, it is provided in particular that the first through-hole has no thread. This advantageously makes it possible for the hinge bracket to be moved relative to the fastening area by turning the screw counter to the first screwing direction. Furthermore, the screw screwed into the first threaded hole limits any movement of the hinge bracket away from the fastening area.

[0010] According to the invention, the threaded pin is arranged in a continuous second threaded bore in the fastening area and rests against the hinge bracket. In other words, the threaded pin can be moved relative to the hinge bracket by turning. The contact of the threaded pin on the hinge bracket limits movement of the hinge bracket towards the fastening area. If the threaded pin rests against the hinge bracket and the screw is not turned, the hinge bracket is fixed along the seal pressure direction. If the threaded pin is turned so that it no longer rests against the hinge bracket but is spaced apart from it, the hinge bracket can be moved towards the fastening area along the seal pressure direction by screwing the screw into the first threaded bore.If the screw is partially unscrewed from the first threaded hole, the hinge bracket can be moved away from the fastening area along the seal pressure direction by screwing the threaded pin into the second threaded hole. Thus, the hinge assembly according to the invention enables advantageously simple adjustment along the seal pressure direction as well as secure fixation of the position of the hinge bracket along the seal pressure direction.

[0011] Advantageous embodiments and further developments of the invention can be found in the dependent claims and the description with reference to the drawings.

[0012] According to a preferred embodiment of the invention, the screw is designed to be screwed into the first threaded bore along the first screwing direction, and the threaded pin is designed to be screwed into the second threaded bore along a second screwing direction. The first screwing direction and the second screwing direction each have a directional component along the seal pressure direction. This advantageously enables good force transmission from the screwed-in screw or the screwed-in threaded pin to the hinge bracket along the seal pressure direction. In particular, the first screwing direction and the second screwing direction are arranged parallel to one another.

[0013] For this purpose, it is preferably provided that the receiving area is tapered along the horizontal direction with respect to the seal pressure direction. This enables secure mounting of the hinge bracket in the receiving area of ​​the cassette while at the same time allowing the hinge bracket to be adjusted along the seal pressure direction. In other words, the receiving area is wider on the frame side than on the side facing away from the frame. The hinge bracket, whose front end is inserted into the receiving area, is thus arranged in the receiving area so that it can be pivoted about an axis arranged at its front end for positioning along the seal pressure direction. The adjustment of the hinge bracket relative to the cassette along the seal pressure direction by means of the screw and the threaded pin is thus brought about by a pivoting movement about an axis which is arranged parallel to the hinge axis at the front end of the hinge bracket.

[0014] For this purpose, it is preferably provided that the first screwing direction and the second screwing direction are each arranged at an angle to the seal pressure direction. For this purpose, it is particularly preferably provided that the first screwing direction and the second screwing direction each have a directional component along the horizontal direction, wherein the first screwing direction and the second screwing direction in particular do not have a directional component parallel to the hinge axis. This advantageously enables excellent force transmission from the screw or the threaded pin to the hinge bracket. By pivoting the hinge bracket during positioning along the seal pressure direction, force would be introduced from the screw onto the thread of the first threaded hole or from the threaded pin onto the surface of the hinge bracket if the first or second screwing direction is arranged parallel to the seal pressure direction.The second screw-in direction occurs at an unfavorable, non-orthogonal angle. The angled arrangement of the screw-in directions takes into account the pivoting movement of the hinge bracket when positioning along the seal pressure direction.

[0015] An embodiment of the present invention is particularly preferred in which the hinge arrangement has a first further threaded pin for adjusting the hinge bracket along the seal pressure direction, wherein the first further threaded pin is arranged in a continuous third threaded bore of the fastening region on the hinge bracket. The first further threaded pin is provided for screwing into the third threaded bore along a third screwing direction, wherein the third screwing direction preferably has a directional component along the seal pressure direction. In particular, it is conceivable that the third screwing direction is arranged obliquely to the seal pressure direction, wherein the third screwing direction preferably has a directional component along the horizontal direction and in particular no directional component parallel to the hinge axis.This advantageously enables a symmetrical and thus uniform force introduction along the vertical direction for adjusting the hinge bracket along the seal pressure direction. Preferably, the third screwing direction is arranged parallel to the second screwing direction.

[0016] For this purpose, it is preferably provided that, relative to a vertical direction parallel to the hinge axis, the screw is arranged between the threaded pin and the first additional threaded pin. The arrangement of the threaded pins in the vertical direction on both sides of the screw enables compensation and prevents any skewing of the hinge assembly.

[0017] According to a further preferred embodiment of the present invention, the first threaded bore, the second threaded bore, and the third threaded bore are arranged centered along a straight line parallel to the hinge axis. Because there is no spacing along the horizontal direction of the threaded pins and the screw, the force introduction for positioning the hinge bracket along the seal pressure direction is very locally limited. Deformations of the hinge bracket along the horizontal direction and the associated inaccuracies in the positioning of the hinge bracket are thus avoided. This advantageously improves the alignment and fixation of the hinge bracket along the seal pressure direction.

[0018] In order to adjust the band arrangement along the horizontal direction, it is preferably provided that the housing has an upper housing part and a lower housing part. For this purpose, the cassette preferably has a fourth threaded bore and a first further screw, wherein the first further screw is screwed into the fourth threaded bore and wherein the first further screw is arranged with a first further screw head in contact with the upper housing part and with a first shaft end in contact with the lower housing part. It is conceivable that the cassette has a fifth threaded bore spaced vertically from the fourth threaded bore and a second further screw, wherein the second further screw is screwed into the fifth threaded bore and wherein the second further screw is arranged with a second further screw head in contact with the upper housing part and with a second shaft end in contact with the lower housing part.

[0019] It is conceivable that the upper housing part and the lower housing part are screwed together. It is also conceivable that the first additional screw head and the second additional screw head are arranged adjacent to an underside of a housing cover of the upper housing part, said cover facing the lower housing part. It is particularly preferably provided that the housing cover has a first opening for operating a first drive profile of the first additional screw head and a second opening for operating a second drive profile of the second additional screw head, wherein the first opening and the second opening are, in particular, elongated holes.

[0020] In other words, the additional screws rest against the housing, so that when the additional screws are turned, the cassette moves inside the housing towards the upper or lower part of the housing. This advantageously enables highly precise adjustability of the cassette and subsequent fixation of the cassette in a horizontal direction. While the movement of the cassette along the horizontal direction occurs intuitively by turning the additional screws, the cassette is fixed in its horizontal position by the frictional force of the additional screws on the housing as soon as the additional screws are no longer actively turned. Preferably, the first shaft end and / or the second shaft end are flattened or rounded.

[0021] Screwing the upper housing section to the lower housing section allows for a secure, yet detachable, connection between the upper and lower housing sections. In particular, by screwing the upper housing section to the lower housing section, the space available for the additional screws can be adjusted horizontally in such a way that the additional screw heads and screw tips are in contact with the upper housing section or the lower housing section. This advantageously ensures that any play in the cassette in the horizontal direction is reduced or even prevented. Alternatively or additionally, it is conceivable for the upper and lower housing sections to be glued or clipped together.

[0022] The openings in the top of the housing only expose the drive profile of the additional screw and are small enough that the part of the additional screw heads arranged around the drive profiles rests against the underside. A particularly advantageous feature here is that the additional screws cannot fall out of the housing, meaning they are permanently installed within the housing. The design of the openings as elongated holes advantageously allows access to the additional screws when the cassette is positioned at different angles along the vertical axis.

[0023] According to a preferred further embodiment of the present invention, the housing has a continuous sixth threaded bore for screwing in a second further threaded pin along a first direction and a continuous seventh threaded bore for screwing in a third further threaded pin along a second direction. For this purpose, the second further threaded pin and / or the third further threaded pin are / is arranged so as to be adjacent to the fastening region arranged between the screwed-in second further threaded pin and the screwed-in third further threaded pin, relative to the hinge axis. The first direction has a directional component in the horizontal direction and a directional component in the vertical direction. The second direction has a directional component in the horizontal direction and a directional component opposite to the vertical direction.It is conceivable for the fastening area to have a first groove and a second groove, wherein the first groove and the second groove are arranged running along the horizontal direction. Preferably, the first groove and the second groove have a V-shaped cross-section, wherein the second further threaded pin rests in the first groove and / or the third further threaded pin rests in the second groove. By screwing the second further threaded pin into the sixth threaded hole or the third further threaded pin into the seventh threaded hole, the part of the cassette arranged between the screwed-in threaded pins, and with it the entire cassette, can be adjusted in the vertical direction. The sixth and seventh threaded holes, which run obliquely to the vertical direction, allow the starting points for vertical adjustment of the cassette to be arranged inside the door or window sash.At the same time, good accessibility from the outside is guaranteed.

[0024] The grooves advantageously improve the vertical fixation of the cassette and its drive during vertical adjustment. The grooves enlarge the contact surface of the second and third setscrews on the cassette's mounting area. This significantly improves the force transmission between the setscrews and the cassette. Furthermore, the grooves enable the second and third setscrews to be guided on the surface of the cassette's mounting area during vertical and horizontal adjustment.

[0025] For this purpose, it is preferably provided that the second additional threaded pin and the third additional threaded pin each have a tip or a conical point. For this purpose, it is provided that the second additional threaded pin is arranged with the tip or the conical point in the first groove and / or the third additional threaded pin is arranged with the tip or the conical point in the second groove. The tips or conical points of the second additional and third additional threaded pin advantageously further enlarge the contact surface in the grooves of the fastening area of ​​the cassette. This results in improved force transmission.

[0026] A further object for achieving the object posed at the outset is a method for adjusting a belt arrangement according to the invention. To adjust the alignment of the cassette in the seal pressure direction, the screw is screwed into the first threaded hole, wherein the threaded pin and preferably the first additional threaded pin are screwed into the second threaded hole or third threaded hole until the threaded pin or the first additional threaded pin are arranged so as to bear against the hinge bracket. To adjust the alignment of the cassette opposite to the seal pressure direction, the screw is partially unscrewed from the first threaded hole, wherein the threaded pin and preferably the first additional threaded pin are screwed into the second threaded hole or third threaded hole until the threaded pin or the first additional threaded pin are arranged so as to bear against the hinge bracket.

[0027] By screwing the screw into the first threaded hole and ensuring that the screw head rests against the contact surface of the fastening area, the hinge bracket is pulled toward the fastening area. If the screw is not turned, it prevents the hinge bracket from moving against the seal pressure direction. The threaded pin on the hinge bracket, and preferably the first additional threaded pin on the hinge bracket, ensures that the hinge bracket is fixed along the seal pressure direction. This provides an advantageously simple yet highly precise way of adjusting the hinge arrangement along the seal pressure direction.It is preferably provided that, in order to adjust the alignment of the cassette in the sealing pressure direction, before screwing the screw into the first threaded hole, the threaded pin is first unscrewed from the hinge bracket and, particularly preferably, the first further threaded pin is unscrewed from the hinge bracket.

[0028] According to a preferred further embodiment of the present invention, in order to adjust the alignment of the cassette in the vertical direction, in a first step, the third additional threaded pin is unscrewed away from the fastening area in the opposite direction to the second direction. Subsequently, in a second step, the second additional threaded pin is screwed along the first direction, resting against the fastening area, in the direction of the third additional threaded pin. In a subsequent third step, the third additional threaded pin is screwed along the second direction until the third additional threaded pin rests against the fastening area.

[0029] By screwing in the second additional threaded pin or the third additional threaded pin at an angle to the vertical direction, an easily manageable option for driving the cassette in the vertical direction is created. This advantageously enables the cassette to be adjusted in the vertical direction and then fixed in the vertical direction. By first screwing the third additional threaded pin away from the fastening area of ​​the cassette arranged between the second additional threaded pin and the third additional threaded pin, movement of the cassette in the direction of the third additional threaded pin is enabled. Then, in the second step, by screwing in the second additional threaded pin, the cassette is moved in the vertical direction towards the third additional threaded pin.In the third step, the third additional threaded pin is screwed into the mounting area of ​​the cassette located between the second additional threaded pin and the third additional threaded pin, until the third additional threaded pin rests against the cassette. The contact of the second additional threaded pin and the third additional threaded pin against the cassette fixes the cassette vertically.

[0030] According to a further preferred embodiment of the present invention, the first additional screw and the second additional screw are turned to align the cassette along the horizontal direction. This advantageously allows intuitive, simple, and precise adjustment of the alignment of the cassette along the horizontal direction. By turning the first additional screw or the second additional screw, the cassette is moved along the horizontal direction relative to the housing. A possible tilt of the cassette can be compensated for by turning the first additional screw and the second additional screw further or less far depending on the tilt.

[0031] All details, features and advantages previously disclosed in connection with the belt arrangement according to the invention also relate to the method according to the invention.

[0032] Further details, features, and advantages of the invention will become apparent from the drawings and the following description of preferred embodiments with reference to the drawings. The drawings merely illustrate exemplary embodiments of the invention, which do not limit the scope of the invention.

[0033] They show: Fig. 1: a side view of a belt arrangement according to an exemplary embodiment of the present invention, Fig. 2: a first sectional view of the Figure 1 shown band arrangement, Fig. 3: a second sectional view of the Figure 1 shown band arrangement, Fig. 4: a third sectional view of the in Figure 1 shown belt arrangement, Fig. 5: an exploded view of a part of the Figure 1 shown band arrangement, Fig. 6: another view of the in Figure 1 shown band arrangement.

[0034] In the figures described below, identical elements are always designated by the same numbers or letters and are therefore not necessarily described multiple times.

[0035] Figure 1 shows a side view of a hinge assembly 100 according to an exemplary embodiment of the present invention for pivotally fastening a door or window sash (not shown) to a door or window frame (not shown) about a hinge axis S. The hinge assembly 100 shown is a concealed hinge assembly 100. This means that the hinge axis S is arranged within a recess in the door or window frame. A hinge bracket 4 of the hinge assembly 100 is connected to the door or window frame by means of a frame-side receptacle (not shown) that is rotatable about the hinge axis S.

[0036] The hinge bracket 4 is inserted along a horizontal direction H into a cassette 3 (see Figures 2 ,3 and 5) of the tape assembly 100 and secured with a screw 6 to a mounting area 3' of the cassette 3. The cassette 3 is only partially visible here, since it is partially arranged in a housing having an upper housing part 1 and a lower housing part 2 screwed to the upper housing part 1. Only the mounting area 3' protrudes from a passage in the upper housing part 1 counter to the horizontal direction. The upper housing part 1 has a housing cover 1.1, which closes off the upper housing part 1 counter to the horizontal direction H.

[0037] A screw head 6.1 of the screw 6 can be seen, which is arranged adjacent to a contact surface 7.3 of the fastening area 3' (see Figure 2 ).

[0038] The screw 6 is arranged between a threaded pin 8 and a first additional threaded pin 10 relative to a vertical direction V parallel to the hinge axis S. Relative to the horizontal direction H, the threaded pin 8, the screw 6, and the first additional threaded pin 10 are arranged at the same height.

[0039] In the Figure 1 Furthermore, a first section plane I, a second section plane II and a third section plane III are marked, which are shown in the Figures 2-4 are shown.

[0040] Figure 2 shows a first sectional view of the Figure 1illustrated tape arrangement 100 according to a preferred embodiment of the present invention. Shown here is a section along the first sectional plane I. The hinge bracket 4, which is mounted rotatably about the hinge axis S, can be seen. The hinge axis S is arranged orthogonal to the plane of the paper in the illustration shown here. The hinge bracket 4 is inserted along the horizontal direction H into a receiving area 5 of the cassette 3. It can be clearly seen that the cassette 3 is arranged in an interior space of the housing formed by the upper housing part 1 and the lower housing part 2. The hinge bracket 4 is secured in the receiving area 5 of the cassette 3 with the screw 6 to prevent it from sliding out of the receiving area 5 counter to the horizontal direction H.

[0041] For this purpose, the screw 6 is screwed along a first screw-in direction A through a first through-hole 7.1 of the fastening area 3' and through a first threaded hole 7.2. The underside of the screw head 6.1 rests against the contact surface 7.3 of the fastening area 3'. The first through-hole 7.1 preferably has no thread. If the screw 6 is screwed into the first threaded hole 7.2 along the first screw-in direction A, the screw head 6.1 is supported on the contact surface 7.3 and the hinge bracket 4 is pulled along a seal pressure direction D that is orthogonal to the hinge axis S and the horizontal direction H. The adjustment of the hinge bracket 4 relative to the cassette 3 along the seal pressure direction D is thus effected by the arrangement of the screw 6 on the fastening area 3' by a pivoting movement about an axis that is arranged parallel to the hinge axis S at the front end of the hinge bracket 4.

[0042] In order to allow the movement of the hinge bracket 4 along the seal pressure direction D, the receiving area 5 is tapered along the horizontal direction H. In order to enable optimal force transmission from the turned screw 6 to the hinge bracket 4 for adjusting the band arrangement 100 along the seal pressure direction D, the first screwing direction A has an angle to the seal pressure direction D.

[0043] However, the illustrated fastening of the hinge bracket 4 with the screw 6 does not fix the hinge bracket 4 in the direction of the seal pressure direction D. To fix the hinge bracket 4 in the direction of the seal pressure direction D, the Figure 3 recognizable threaded pin 8 is provided. Figure 3 shows the Figure 1illustrated hinge arrangement 100 according to a preferred embodiment of the present invention in a sectional view. The second sectional plane II is shown. The threaded pin 8 is screwed along a second screwing direction B into a second threaded bore 9 of the fastening area 3' and bears against the hinge bracket 4. By the threaded pin 8 bearing against the hinge bracket 4, the hinge bracket 4 is limited in a movement along the sealing pressure direction D. Since the screwed-in screw 6 (see Figure 2 ) fixes the hinge bracket 4 against the seal pressure direction D and the threaded pin 8 rests on the hinge bracket 4 and thus does not allow any movement along the seal pressure direction D, the hinge bracket 4 is fixed in the seal pressure direction D.

[0044] The Figure 1 The first further threaded pin 10 shown is inserted into a third threaded hole 11 (see Figures 4 and 5) and also rests on the hinge bracket 4. The arrangement of the screw 6 between the threaded pin 8 and the first further threaded pin 10 ensures a symmetrical transmission of force from the screw 6, the threaded pin 8 and the further threaded pin 10 to the hinge bracket 4.

[0045] Figure 4 shows a third sectional view of the Figure 1illustrated hinge arrangement 100. The third sectional plane III is shown. Here, the first additional threaded pin 10 can be seen, which is arranged adjacent to the fastening area 3'. The screw 6 is arranged between the threaded pin 8 and the first additional threaded pin 10. This results in a stable fixation of the hinge bracket 4 in the seal pressure direction D. Furthermore, a first additional screw 14.1 with a first additional screw head 14.3 can be seen through a first opening 15.1 and a second additional screw 14.2 with a second additional screw head 14.4 can be seen through a second opening 15.2. The first additional screw 14.1 and the second additional screw 14.2 are used for the horizontal adjustment of the hinge arrangement (see Figure 5 ).

[0046] Figure 5 shows an exploded view of part of the Figure 1shown band arrangement 100. Only the hinge bracket 4 is omitted here. The upper housing part 1, which is screwed together with the lower housing part 2 to form the housing using connecting screws 19, is clearly visible. The cassette 3 is arranged in the interior of the housing. The first through-hole 7.1, the second threaded hole 9 and the third threaded hole 11 of the fastening area 3' of the cassette 3 are clearly visible. Also shown are the threaded pin 8, which is screwed into the second threaded hole 9 along the second screwing direction B, and the first further threaded pin 10, which is screwed into the third threaded hole 11 along a third screwing direction C. The third screwing direction C is arranged parallel to the second screwing direction B.

[0047] To adjust the belt arrangement 100 along the horizontal direction, the belt arrangement 100 has the first additional screw 14.1, which is screwed into a fourth threaded hole 13.1 along the horizontal direction H in the cassette 3, and the second additional screw 14.2, which is screwed into a fifth threaded hole 13.2 along the horizontal direction H in the cassette 3. The first additional screw head 14.3 of the first additional screw 14.1 rests on an inner side of the housing cover 1.1. Furthermore, a first shaft end 14.5 of the first additional screw 14.1 rests on the housing base 2. A driving profile of the first additional screw head 14.3 can be operated from the outside through a first opening 15.1 in the housing cover 1.1. The second additional screw head 14.4 of the second additional screw 14.2 rests on an inner side of the housing cover 1.1. Furthermore, there is a second shaft end 14.6 of the second further screw 14.2 on the housing base 2. A drive profile of the second additional screw head 14.4 can be operated from the outside through a second opening 15.2 in the housing cover 1.1. If the first or second additional screw 14.1, 14.2 is turned, the cassette 3 and, with the cassette 3, the hinge bracket 4 move along the horizontal direction H toward the housing top 1 or the housing bottom 2.

[0048] To adjust the belt arrangement 100 along the vertical direction V, the second additional threaded pin 17 and a third additional threaded pin 18 are provided. The first additional threaded pin 17 is screwed into the sixth threaded bore 16.1 along the first direction E and rests with a conical tip in a V-shaped first groove 20 arranged along the horizontal direction H on the fastening area 3'. The third additional threaded pin 18 is screwed into a seventh threaded bore 16.2 along a second direction F and rests with a conical tip in a V-shaped second groove 21 arranged along the horizontal direction H on the fastening area 3'. The fastening area 3' is arranged between the second additional threaded pin 17 and the third additional threaded pin 18. To move the cassette 3 along the vertical direction V, the third additional threaded pin 18 is first screwed away from the fastening area 3'.The second further threaded pin 17 is then screwed in along the first direction E so that it rests against the fastening area 3'. This causes the cassette 3 to move along the vertical direction V. Once the cassette 3 is arranged in the correct position in the vertical direction V, the third further threaded pin 18 is screwed in along the second direction F until it rests in the second groove 21 on the fastening area 3'. The first direction E has a directional component along the vertical direction letter V and a directional component along the horizontal direction H. The second direction F has a directional component along the horizontal direction H and a directional component opposite to the vertical direction V. The first direction E being arranged at an angle to the vertical direction V and the second direction F being arranged at an angle to the vertical direction V ensure an optimally arranged contact surface for the second orthird additional threaded pin 17,18 while still allowing good accessibility of the second or third additional threaded pin 17,18 from the outside.
