Description

[0001] The following statements relate to a hinge, in particular for a swing door, the hinge comprising a frame hinge, a leaf hinge which is connected to the frame hinge via an axis element defining a zero position of the leaf hinge, and a return device for providing a return moment which can return the leaf hinge to the zero position in a pivot position deviating from the zero position.

[0002] Known hinged belts with adjustable zero position are complex in design, expensive to manufacture and difficult to operate.

[0003] Based on this situation, the present object is to provide a hinged belt in which adjustment of the zero position can be simplified and cost-effectively provided and a long service life of the hinged belt can be maintained. In particular, the object is to avoid or reduce the disadvantages of solutions known from the prior art.

[0004] The present object is achieved by the features of the independent claims. Advantageous embodiments are specified in the subclaims, the description, and the drawings. To the extent technically feasible, the teachings of the subclaims may be combined arbitrarily with the teachings of the main and subclaims.

[0005] In particular, the object is achieved by a hinge, in particular for a swing door or shower door or shower partition. The hinge has a frame hinge, a sash hinge, a return device and a clamping element. The sash hinge is pivotally connected to the frame hinge, for example via an axle element held in the frame hinge and defining a zero position of the sash hinge, for example through its rotational position in the frame hinge. The return device is provided, for example, to provide a return torque acting between the axle element and the sash hinge. In particular, the return torque can return the sash hinge to the zero position in a pivoted position deviating from a zero position. The clamping element is provided, for example, for releasably clamping or fixing the axle element in the frame hinge.In particular, it is proposed that the clamping element is held in the frame band so as to be rotatable about a clamping axis and has a clamping contour which runs at least partially in the circumferential direction around the clamping axis for engagement with the axis element.

[0006] In other words, a hinged hinge is proposed that has a frame hinge and a sash hinge pivotally attached thereto. An axle element rotatably held in the frame hinge can be clamped or fixed by a clamping element rotatably held in the frame hinge in order to set a zero position. The sash hinge is pivotally attached to the frame hinge via the axle element and a reset device, wherein the reset device can generate a reset moment when the sash hinge pivots out. The reset device typically provides the reset moment and rotatability between the axle element and the sash hinge. The clamping element has a circumferential clamping contour for clamping the axle element by rotating the clamping element.

[0007] Furthermore, the problem is solved, for example, by a swing door, in particular a shower cubicle or shower partition, or by a shower cubicle or shower partition with a swing door. The swing door or the shower cubicle / shower partition has a hinge, in particular the hinge described here, or is or can be attached therewith, e.g., to a wall.

[0008] Furthermore, the problem is solved, for example, by using the hinge band to fasten a swing door, for example a swing door of a shower cubicle and / or a swing door of a shower room.

[0009] The invention enables simple adjustment and fixing of the zero position of the hinge, whereby the axle element is easily releasably clamped and remains in this position. Adjusting the zero position does not require any laborious disassembly of the hinge or the door. The zero position adjustment is reversible and durable. Clamping allows tolerances of the components involved in the clamping to be compensated. The design typically requires few components and can therefore usually be provided cost-effectively.

[0010] The hinge is to be understood in particular as a door hinge or door joint, in particular for a swing door. The hinge typically comprises a wall-side or door frame-side part, for example the frame hinge, and a door leaf-side part, for example the leaf hinge. The frame hinge typically provides a mounting side or mounting surface that can be attached, for example, to a surface of a wall or the like on which a door is to be pivoted. The frame hinge has, for example, fastening options, e.g. holes, to attach the frame hinge using fastening elements, e.g. screws. The leaf hinge typically provides a fastening option for a door leaf. In use, the leaf hinge usually forms the pivoting part of the hinge, while the frame hinge is usually rigidly attached.

[0011] The frame hinge and the sash hinge can be pivoted towards each other, e.g. to open or close the door fitted with or attached to it. The sash hinge is in its pivoted position and is in the zero position. In the zero position, there is generally no restoring torque from the restoring device. For example, a door fitted with the hinge is locked in the zero position. In other pivoted positions, the restoring torque generally points towards the zero position in order to automatically move the sash hinge into the zero position. The zero position must be set, for example, when the hinge is first fitted and readjusted from time to time.

[0012] The axle element is provided for connecting the frame hinge and sash hinge. The axle element is typically held in the frame hinge so it can rotate about a / the pivot axis of the hinge. The clamping element is typically held in the frame hinge so it can rotate about the clamping axis. The clamping element can reversibly clamp the axle element or secure it in the frame hinge so that it cannot rotate. For example, the clamping element and / or the axle element is / are inserted into recesses in the frame hinge and can rotate therein. Typically, the axle element rotates when not clamped so that a desired zero position can be set so that the axle element can then be fixed in place or clamped using a clamping element. The clamping can then transmit torque, for example the restoring torque.

[0013] For example, the axis element is a cylindrical bolt, which is oriented along the pivot axis and / or can be rotated around the pivot axis in the frame hinge. Typically, the axis element does not provide the pivoting capability between the sash hinge and the frame hinge, but rather, through its rotatability, the adjustability of the zero position. Therefore, rotation or rotatability of the axis element should preferably be used to adjust the zero position.

[0014] The return mechanism can provide a return torque acting between the axis element and the sash hinge. The return torque can return the sash hinge to the zero position in a pivot position deviating from the zero position. For example, the return mechanism can be tensioned when pivoting from the zero position or can have a gravity-assisted mechanism.

[0015] To engage the axle element or to clamp the axle element, the clamping element has a clamping contour that runs at least partially in the circumferential direction around the clamping axis. For example, the clamping element has a circumferential projection and / or recess that is designed to clamp the axle element. Typically, the clamping element is designed to clamp the axle element laterally. For example, the clamping axis lies next to the pivot axis or does not intersect the pivot axis. For example, the clamping element is not designed to clamp the axle element on the end face, as is the case with a grub screw pressing against the axle element.

[0016] Advantageous aspects and further preferred embodiments are described and explained below. Explanations, particularly regarding advantages and definitions of features, are by their nature descriptive and preferred, but not limiting, examples. If an explanation is limiting, this will be expressly stated.

[0017] It can be provided that the clamping axis runs transversely, preferably perpendicularly, to a / the pivot axis of the hinge. The clamping axis is preferably spaced from the pivot axis. The clamping axis and the pivot axis preferably do not intersect. For example, the clamping axis runs essentially parallel to the mounting side or mounting surface of the frame hinge.

[0018] Preferably, the clamping contour has a distance from the clamping axis that is variable in the circumferential direction around the clamping axis, at least in sections and preferably monotonically, in particular strictly monotonically. In particular, the distance decreases or increases in the circumferential direction. In other words, for example, the clamping contour is shaped with a radius that is variable in the circumferential direction, in particular at least in sections and preferably monotonically or strictly monotonically increasing or decreasing. The clamping contour can be shaped to extend continuously in the circumferential direction, at least in sections. For example, the clamping contour can be shaped discontinuously in the circumferential direction in a transition from a lowest to a highest distance from the clamping axis.

[0019] The clamping contour preferably runs spirally in the circumferential direction around the clamping axis, at least in sections. For example, the clamping contour is designed such that a distance between the clamping contour and the clamping axis decreases or increases at least in sections and in particular monotonically and / or continuously in the circumferential direction. The clamping contour can, for example, be designed as an eccentric, at least in sections. Thus, rotation of the clamping element can lead to the clamping contour finally coming into contact with the axis element in order to clamp it. Such a design improves the longevity of the hinge hinge. Experience has shown that there is little to no transverse movement of the axis element when clamped by the clamping element, so that neither the zero position nor the door leaf height are significantly influenced by the clamping. High tolerances can be compensated for.The clamping contour enables, in particular, a continuous increase in force between the clamping element and the axle element.

[0020] It can be provided that the clamping contour is concave, for example in a longitudinal sectional view with respect to the clamping axis or viewed in the circumferential direction. This concave shape can also be visible in a plan view of the clamping element transverse to the clamping axis. The clamping contour can be shaped, for example at least in regions or continuously, with a first radius. A clamping region of the axis element that is in particular cylindrical at least in regions can be shaped with a second radius. The second radius can correspond to half a diameter of the clamping region. In particular, the first radius is adapted to the second radius, for example substantially as large as the second radius, for example at most 30%, at most 20%, or at most 10% different therefrom. The first radius can correspond to the second radius, be smaller than it, or be larger than it.For example, the first radius can be smaller than the second radius, for example, wherein the clamping element, at least in the region of the clamping contour, can be formed from a softer material than the axle element, at least in the region of the clamping area. The first radius, for example, is initially smaller than the second radius in the non-adhering or unclamped state and adapts to the second radius, in particular through elastic and / or plastic deformation, upon clamping or abutment thereon. This configuration can increase the contact surface between the clamping element and the axle element and improve longevity by reducing material stress.

[0021] It can be provided that the clamping element and / or the axle element has / have cylindrical outer surfaces at least in sections. In particular, the clamping element and / or the axle element is / are substantially cylindrical and / or pin-shaped. The frame hinge can have a first cylindrical recess, for example a bore, running along the clamping axis for receiving the clamping element. The frame hinge can have a second cylindrical recess, for example a bore, running along a / the pivot axis of the hinge hinge for receiving the axle element. Preferably, the two recesses intersect in the region of the clamping contour, in particular so that the clamping and axle elements can come into contact within the frame hinge. The respective receptacle enables rotation of the respective clamping or axle element.Advantageously, the clamping of the axle element by the clamping element can ensure that both elements are held in a rotationally fixed manner and are axially secured, so that torque transmission between the axle element and the frame band is possible and both elements are protected against loss.

[0022] It can be provided that the clamping element has a recess, in particular arranged laterally on the clamping element and / or axially adjacent to the clamping contour. The recess can extend over part of an axial length of the clamping element and / or starting from one end or end face of the clamping element and preferably as far as a radially lowest point of the clamping contour with respect to the clamping axis. The recess is preferably flat, at least in some regions. The recess can run parallel to the clamping axis. The recess can be a flattened portion of the clamping element. For example, the recess is shaped such that, in the case of recesses that intersect in the frame band, the clamping element can be inserted into the other recess without collision when the axis element is inserted into one recess. The recess enables and / or facilitates assembly of the clamping element.

[0023] The clamping element can be provided with a tool engagement option on at least one end face of the clamping element, for example, a hexagon socket, a Torx socket, a slotted receptacle, and / or a cross receptacle. For example, the clamping element has two opposing end faces or ends. The tool engagement option can be provided, for example, incorporated, on exactly one of the end faces, and only optionally on both end faces. The tool engagement option offers a compact shape, simple adjustment, and is easy to conceal.

[0024] The frame hinge may have a wall-side section and an axle-side section. Preferably, the wall-side section is integrally or monolithically connected to the axle-side section. Preferably, the sash hinge encompasses the axle-side section. The axle element and / or the clamping element may be retained in the axle-side section. It is preferred that the clamping element on the axle-side section be accessible from the outside, for example, to insert a tool from the outside and rotate the clamping element.

[0025] The hinge preferably has a cover, for example for covering the axis-side section and / or the clamping element. The cover can be attached to the sash hinge and / or configured for pivoting movement together with the sash hinge. The cover can be provided for covering along the clamping axis on one or both sides of the clamping element. The cover can provide protection against the ingress of moisture. The cover can be detachably attached, for example plugged, clipped, or the like. The cover can be formed with or from metal material and / or plastic material, for example from metal-coated plastic.

[0026] It can be provided that the frame hinge, the sash hinge, the clamping element, and / or the axle element is / are made with or from one or more metal materials, in particular a steel alloy, a brass alloy, and / or an aluminum alloy. Aluminum and brass, in particular, are characterized by easy machinability and sufficient mechanical strength, which allows the hinge and / or frame hinge to be produced economically. For the axle element and / or the clamping element, as they are typically rather small components subject to high mechanical stress, steel alloys are preferred, for example, material number 1.4301 or AISI 304 and / or V2A.

[0027] The return device can provide the restoring moment in various ways, for example by spring force, by hydraulically applied force, and / or by gravity. Preferably, a mechanism is provided which provides the restoring moment based on gravity, for example by lifting the sash hinge from a moment-free rest position or the zero position during a pivoting movement and gravity inducing the restoring moment through kinematics. In particular, it can be provided that the return device has a lifting / lowering component or a lifting / lowering sleeve. The lifting / lowering component is preferably connected to the axle element in a rotationally fixed manner or is connected thereto, in particular placed thereon. For torque transmission, the lifting / lowering component is connected to the axle element, e.g., in a form-fitting, material-fitting and / or force-fitting manner, e.g., screwed, pinned, pressed, glued, formed integrally therewith, and / or riveted.The lifting / lowering component can provide the kinematics. The lifting / lowering component is preferably made of or with plastic, in particular polyoxymethylene or POM. Alternatively or additionally, the lifting / lowering component can be made of or with one or more of the metal materials mentioned here.

[0028] The lifting / lowering component has, in particular to provide the kinematics, for example, opposite run-on slopes with respect to a pivot axis of the hinge. The sash hinge, in particular a bolt of the restoring device fastened in the sash hinge, can run onto the run-on slopes when rotating about the pivot axis, in particular in order to be displaced along the pivot axis and generate the restoring moment by weight. The bolt can be made with or from one or more of the metal materials mentioned here. Such a lifting / lowering function allows the generation of an essentially continuously large restoring moment without springs or dampers.

[0029] The lifting and lowering component can have a locking groove. The bolt can lock on or in the locking groove when the hinge is pivoted open, in order to automatically hold this position without restoring torque. The locking groove is arranged, for example, at a pivot angle of 90° with respect to the zero position. The locking groove can be designed such that a locking action is present in both pivot directions of the sash hinge relative to the frame hinge. The locking groove can be raised above the rest position or zero position, in particular by at least 1 mm and up to 10 mm, preferably by 5 mm ± 2.5 mm.

[0030] In the context of the disclosure, the abbreviation "bzw." (respectively) is a short form for "respectively" and is generally intended to indicate alternative, essentially equivalent, and / or synonymous features or terms in order to convey the idea or meaning of a feature or term. "Respectively" and "or" can always be replaced by "and / or." Optional features, i.e., those disclosed in conjunction with "in particular," "for example," "preferably," "preferably," "optional," "can," or the like, can be used individually to further develop the invention.

[0031] A preferred technical solution is explained in more detail below with reference to the accompanying drawings using preferred embodiments. The term "figure" is abbreviated to "Fig." in the drawings. The drawings show Fig. 1A-B a hinge with a frame hinge and a sash hinge in perspective views, namely in a non-transparent representation (1A) and in a partially transparent representation (1B); Fig. 2A-C the joint band from Fig. 1A-B with the sash hinge (2A) hidden to show a return device, with the return device and transparent frame hinge (2B) hidden to show a clamping element and an axis element, and with views only of the clamping element (2C); Fig. 3 the joint band Fig. 1A-B or Fig. 2A-C with hidden sash hinge and hidden reset device in a side view; Fig. 4A-B the joint band Fig. 3 in a sectional view with a cutting plane (4A) lying in a pivot axis and arranged perpendicular to a clamping axis, and in a transparent view with a view parallel to the pivot axis (4B), wherein the clamping element is in a released rotational position or is not in contact with the axis element; and Fig. 5A-B the hinge in views as in Fig. 4A (5A) or Fig. 4B (5B), wherein the clamping element is in a rotational position clamping the axle element or resting against it.

[0032] Fig. 1A-B shows a hinge 1 with a frame hinge 10 and a sash hinge 20. The sash hinge 20 is pivotably connected to the frame hinge 10 about a pivot axis S via an axle element 30 held in the frame hinge 10. The axle element 30 defines a zero position of the sash hinge 20 relative to the frame hinge 10. In the present case, the axle element 30 defines the zero position through its pivoting position or rotational position about the pivot axis S relative to the frame hinge 10. The axle element 30 is generally rotatably held in the frame hinge 10, but in the present case and in the normal operating state, in which the zero position is to remain permanently set, it is connected to the frame hinge 10 in a rotationally fixed manner by being releasably clamped. The axle element 30 extends in the present case along the pivot axis S. By way of example, the sash hinge 20 assumes the zero position relative to the frame hinge 10.

[0033] The hinge 1 comprises a return device 40, which can provide or provides a return moment acting between the axis element 30 and the sash hinge 20. The return moment is intended to return the sash hinge 20 from a pivot position deviating from the zero position to the zero position.

[0034] Furthermore, a clamping element 50 is provided, which allows a releasable clamping of the axis element 30 in the frame hinge 10. The clamping element 50 ensures a releasable, rotationally fixed connection of the axis element 30 to the frame hinge 10. When the clamping is released, the zero position can be adjusted by rotating the axis element 30 together with the sash hinge 20.

[0035] When—with the axis element 30 normally clamped—the sash hinge 20 is pivoted relative to the frame hinge 10 about the pivot axis S and out of the zero position, the reset device 40 automatically generates the reset torque. The reset torque acts between the axis element 30 and the sash hinge 20, preferably until the sash hinge 20 returns to its zero position. The zero position can be adjusted by rotating the axis element 30.

[0036] Fig. 2A-C shows further details from Fig. 1A-B. The clamping element 50 is mounted or held in the frame hinge 10 so as to be rotatable about a clamping axis K. The clamping axis K runs essentially parallel to a mounting side or mounting surface of the frame hinge 10. As can be seen, the clamping element 50 has a clamping contour 52 for engagement with the axis element 30, which extends at least partially in the circumferential direction around the clamping axis K. It can be seen that the clamping axis K runs transversely or perpendicularly to the pivot axis S of the hinge 1 and is spaced apart from it.

[0037] The clamping contour 52 has a distance to the clamping axis K that is at least partially or partially circumferentially and continuously or monotonically variable in the circumferential direction around the clamping axis K.

[0038] The clamping contour 52 extends in the circumferential direction around the clamping axis K at least in sections in a spiral shape.

[0039] By rotating the clamping element 50, a local distance to the axis element 30 can be adjusted continuously or steplessly, in particular up to the clamping.

[0040] In the present case, the clamping contour 52 extends in the circumferential direction over at least half the circumference of the clamping element 50 or over at least 180° or at least 225° or at least 270° or more.

[0041] The clamping contour 52 is concave and has a first radius R1. In the present case, the first radius R1 is adapted to a second radius R2 of an at least partially cylindrical clamping region 32 of the axle element 30. For example, the radii R1 and R2 are essentially the same size, deviating from each other by at most ± 10%.

[0042] It is possible that the first radius R1 is smaller than, as large as, or larger than the second radius R2.

[0043] With a view to Fig. 2C, the clamping element 50 has a recess 54 that extends over part of an axial length 56 of the clamping element 50. The recess 54 begins at an end 58 of the clamping element 50 and extends at least to a radially lowest point of the clamping contour 52 with respect to the clamping axis K. In the present case, the recess 54 is flat. The recess 54 enables easy assembly.

[0044] The clamping element 50 and the axle element 30 have cylindrical outer surfaces, at least in sections. In particular, the clamping element 50 and the axle element 30 are essentially pin-shaped.

[0045] The frame band 10 has a first cylindrical recess 11 or cylindrical bore running along the clamping axis K for receiving the clamping element 50 and a second cylindrical recess 12 or second cylindrical bore running along the pivot axis S for receiving the axle element 30. The recesses 11, 12 intersect in the area of the clamping contour 52 or enable, for example, the clamping area 32 to be clamped by the clamping contour 52 when the axle element 30 and clamping element 50 are held by the frame band.

[0046] The clamping element 50 has a tool engagement possibility on at least one end face 60, for example in the form of a hexagon socket, in order to enable easy rotation or adjustment of the clamping element 50 by means of a tool.

[0047] The frame hinge 10 has a wall-side section 14 and an axis-side section 16 integrally connected to the wall-side section 14. These sections are formed monolithically with one another, for example, machined from a solid material or joined together by a material bond. The sash hinge 20 surrounds the axis-side section 16, see FIG. Fig. 1A-B. The axle element 30 and the clamping element 50 are held in the axle-side section 16, in particular in a rotatable manner. A cover 2 covers the axle-side section 16 and the clamping element 50, see. Fig. 1A-B.

[0048] The frame hinge 10 and the sash hinge 20 are made of a brass alloy. The clamping element 50 and the axle element 30 are made of a steel alloy, preferably material number 1.4301 or V2A.

[0049] The return device 40 has a lifting / lowering component 42 that is non-rotatably connected to the axle element 30 and is formed, for example, with or from plastic, in particular polyoxymethylene or POM. The lifting / lowering component 42 has run-up slopes 44 opposite the pivot axis S. A bolt 46 of the return device 40, which is fastened in the leaf hinge 20, runs against the run-up slopes 44 upon rotation about the pivot axis S. This displaces the bolt 46 along the pivot axis S, so that the restoring moment is generated by weight. Essentially, a door leaf fastened to the leaf hinge 20 is lifted to provide the weight.

[0050] In the present case, the lifting / lowering component 42 has a locking groove 45, into which the bolt 46 can engage in a pivoted-up position of the hinge 1, in order to automatically maintain this position without a restoring moment. The locking groove 45 is arranged, for example, at a pivot angle of 90° relative to the zero position.

[0051] The lifting-lowering component 42 is connected to the axle element 30 in a rotationally fixed manner, for example by pinning, screwing or pressing.

[0052] In this case, the rotational position of the axis element 30 defines the rotational position of the lifting / lowering component 42 and thus also the zero position. In order to adjust the zero position, the lifting / lowering component 42 must be rotated.

[0053] The run-up slopes 44 are designed to provide a stroke of at least 1 mm and at most 10 mm, preferably 5 mm ± 2 mm, over a pivot angle of 90°.

[0054] The reset device 40 is provided in duplicate so that one of the reset devices 40 can be used to provide the reset torque when the hinge 1 is mounted on the left or right side. One of the reset devices 40 is arranged at each of the opposite ends of the axle element 30.

[0055] With a view to Fig. 3 shows a side view looking parallel to the clamping axis K and transverse to the pivot axis S. Here, for example, it can be seen that the cylindrical recesses 11, 12 intersect in the axis-side section 16. The clamping element 50 can be rotated (here counterclockwise) to release the axis element 30 or to bring it into a released position and thus make it rotatable relative to the frame hinge 10 so that the zero position can be set or the axis element 30 can be rotated. The clamping element 50 can also be rotated (here clockwise) to bring the clamping element 50 into a position resting on the axis element 30 or to clamp the axis element 30 and thus arrange it in the frame hinge 10 in a rotationally fixed manner and to fix its rotational position so that the zero position can be fixed. In this case, an Allen key can be used to turn the clamping element 50.

[0056] In Fig. 4A-B shows a released position of the clamping element 50, in which the clamping contour 52 is not in contact with the axle element 30. In this arrangement, the zero position can be adjusted by rotating the axle element 30. Here, the axle element 30 can be connected or is to be connected to the frame hinge 10 in a rotationally fixed manner. In other words, the axle element 30 can rotate freely and is not clamped. In order to clamp the axle element 30 or arrange it in a rotationally fixed manner, the clamping element 50 can be turned, for example, using an Allen key. The spiral-shaped clamping contour 52 then ensures that a gap or play between the clamping contour 52 and the clamping area 32 is gradually reduced until the axle element 30 is clamped.

[0057] In Fig. Finally, Figures 5A-B show a resting position in which the clamping contour 52 rests against or clamps the axle element 30. Here, the axle element 30 is connected to the frame strip 10 in a rotationally fixed manner and defines the zero position.

[0058] Fig. 4A shows a cross-sectional view of the clamping axis K, with the section located in the pivot axis S or in the middle of the clamping contour 52. As can be seen, the clamping contour 52 extends spirally in the circumferential direction around the clamping axis K.

[0059] As can be seen, the clamping contour 52 has a continuously and monotonically variable distance to the clamping axis K in the circumferential direction around the clamping axis K.

[0060] The clamping contour K is formed with a radius that varies in the circumferential direction, more precisely, a radius that increases or decreases in sections in a strictly monotonous manner, whereby in the present case this radius is visible in a cross-sectional view with respect to the clamping axis K.

[0061] In particular, the clamping contour K runs continuously in the circumferential direction in sections and there is a discontinuous transition from a lowest to a highest distance to the clamping axis K.

[0062] Basically, the clamping contour 52 is designed eccentrically in sections.

[0063] The clamping element 50 can be in the Fig. 4A, in order to bring it into flat contact with the axis element 30, in this case in particular clockwise. Due to the rotation, the clamping contour 52 partially surrounds the axis element 30 as seen along the clamping axis K. Due to the shape or spiral shape of the clamping contour 52, the clamping contour 52 approaches the axis element 30 during the rotation and depending on the rotational position of the clamping element 50, until it finally comes into contact, in particular as shown in Fig. 5A is shown.

[0064] In this case, the clamping contour 52 is not applied to the axis element 30 at specific points but essentially in a linear and / or curved manner, cf. Fig. 5A-B. The clamping contour 52 is formed in the circumferential direction with the first radius R1, which corresponds to or is adapted to the second radius R2 of the clamping area 32 of the axle element 30.

[0065] The function of the clamping mechanism using the spiral clamping contour 52 is similar to that of a clamping mechanism using an eccentric, however, the center point of the first radius R1 adjacent to the axis element 30 or the clamping area 32 is always centered on the clamping element 50. An eccentric can also be rotated by only a small angular range of, for example, 180°, after which the clamping force decreases again. With the spiral clamping contour 52, a rotation of, for example, approximately 270° or more is possible.

[0066] In particular, the spiral clamping contour 52 has, circumferentially or in the circumferential direction around the clamping axis K or around the clamping element 50, essentially the radius of the axis element 30. This means, in particular, that the first radius R1, which defines the concave shape of the clamping contour, corresponds to the second radius R2, which essentially defines the shape of the lateral surface of the axis element 30. The clamping contour 52, in particular, continuously encloses a circumferential section of the lateral surface of the axis element 30, or in every rotational position of the axis element 30. In particular, there is no point pressure on the axis element 30, so that the material of the axis element 30 is deformed little or not at all during clamping and each zero position can be set reversibly, i.e., multiple times.
