Description

[0001] The invention relates to a fixing device for a fastening device for fixing a storage body to a storage surface of a storage device, comprising at least one base which can be fixed directly or indirectly to the storage surface of the storage device, comprising at least one housing which includes the base or which is fixed to the base, comprising at least one clamping element which is arranged outside the housing on a side of the housing facing away from the base and which is movable relative to the housing, and comprising at least one actuating unit which includes at least one actuating element on which the clamping element is fixed relative to the actuating element in a rotationally and positionally fixed manner, and which includes at least one actuator by which the actuating element and the clamping element fixed thereto can be moved from a release position to a pre-clamping position by rotation about an axis of rotation extending transversely to the storage surface.in which the actuating element and the clamping element are rotated relative to the axis of rotation with respect to the release position and are fixed against further rotation about the axis of rotation, and can be moved from the pre-clamping position by the actuating element and the clamping element by translational movement parallel to the axis of rotation towards the housing into a clamping position in which a distance between the clamping element and the support surface is reduced relative to the pre-clamping position, wherein the housing comprises a housing cavity in which the actuating element is arranged at least section by section and the actuating element bears against an inner surface section of the housing, in particular over a surface, with an outer surface section rotationally symmetrical with respect to the axis of rotation, wherein the actuating element is rotatable with respect to the axis of rotation and movable parallel to the axis of rotation relative to the housing.

[0002] Securing devices for a fastening device for securing a storage body to a storage surface of a storage device are known in the prior art in various designs. In these devices, the securing device is fixed to a storage surface of the storage device, and a clamping element of the securing device is positioned above a storage body and tightened by means of tools until the storage body to be clamped is clamped to the storage surface by the securing device.

[0003] Depending on the accessibility of the clamping element of the fixing device, which is intended to clamp the storage body in place, a tool for tightening the clamping element may be difficult to reach, and tightening the clamping element with the tool may prove cumbersome. If the clamping element is already fixed to the fixing device, positioning the fixing device on the storage surface may prove difficult if the geometry of the storage body to be fixed restricts access to the storage surface.

[0004] Type-specific fixing devices are known from US 5,013,015 A and US 2020 / 070317 A1.

[0005] One object of an embodiment of the invention is to propose a fixing device for a fastening device for fixing a storage body to a storage surface of a storage device, in which the arrangement of a storage body to a storage surface and the fixing of the storage body by the fixing device are improved.

[0006] This task is solved in the case of a fixing device mentioned at the outset for a fastening device for fixing a storage body to a storage surface of a storage device by the fact that the fixing device comprises at least one guide unit which includes at least one groove-like receptacle in the inner surface section of the housing, at least one guide cam formed by a recess on the outer surface section of the actuating element and at least one guide pin engaging in the receptacle and guide cam.

[0007] By providing a guide unit, the transition from the release position to the pre-clamping position and from the pre-clamping position to the clamping position can be easily provided mechanically as kinematics through structural conditions and shaping.

[0008] Because the housing includes a housing cavity in which the actuating element is arranged at least partially, and the actuating element with an outer surface section rotationally symmetrical with respect to the axis of rotation abuts an inner surface section of the housing rotationally symmetrical with respect to the axis of rotation, in particular in a planar fashion, wherein the actuating element is rotatable with respect to the axis of rotation and movable parallel to the axis of rotation relative to the housing, the actuating element can be guided and held in a simple manner when moving from the release position to the pre-clamping position and from the pre-clamping position to the clamping position.

[0009] Because the fixing device includes an actuating unit in which the actuating element and the actuator interact in such a way that the actuating element and the clamping element attached to it can be moved from a release position to a pre-clamping position by rotating about a rotation axis running transversely to the storage surface, the clamping element can already be pre-mounted on the fixing device and moved by the actuator from the release position, in which the clamping element allows the storage body to be placed on the storage surface without collision, to the pre-clamping position, in which the clamping element is positioned above the storage body for clamping and fixing it.

[0010] Because the clamping element's actuator can be moved from the pre-clamping position to the clamping position by translational movement parallel to the axis of rotation towards the housing, the storage body can be clamped in a simple way.

[0011] By providing an actuator, it is not absolutely necessary for the clamping element to be directly accessible with a tool. The actuator can be positioned on the locking device in a way that is always collision-free and easily accessible by a tool or operator.

[0012] In the clamping position, the distance between the clamping element and the support surface is reduced compared to the pre-clamping position; this means that the clamping element is moved from its position in the pre-clamping position towards the support surface in order to reach the clamping position.

[0013] In embodiments of the locking device, it proves advantageous if, in addition to rotation about the axis of rotation, the transfer of the actuating element from the release position to the pre-clamping position includes a translational movement parallel to the axis of rotation towards the housing and / or if the clamping element in the pre-clamping position is arranged in alignment with the storage body in a direction parallel to the axis of rotation.

[0014] If, in addition to rotating around the axis of rotation, the movement of the actuator from the release position to the pre-clamp position includes a translational movement parallel to the axis of rotation towards the housing, the distance to the storage surface can be reduced as soon as the actuator is moved from the release position to the pre-clamp position.

[0015] If the clamping element is aligned with the support body in the pre-clamping position, parallel to the axis of rotation, the transition from the pre-clamping position to the clamping position can only be achieved by a translational movement parallel to the axis of rotation. This results in simplified kinematics for the transition from the pre-clamping position to the clamping position.

[0016] The guide unit can, in principle, be of any design, provided it defines the kinematics for transitioning from the release position to the pre-clamping position and from the pre-clamping position to the clamping position. This can be easily ensured if the guide track includes a first guide section that runs transversely or obliquely to the axis of rotation, which extends, in particular, parallel to the axis of rotation towards the clamping element and defines the transition of the actuating element from the release position to the pre-clamping position, and if the guide track includes a second guide section into which the first guide section merges and which runs parallel or obliquely to the axis of rotation, which blocks further rotation about the axis of rotation and defines the transition of the actuating element from the pre-clamping position to the clamping position.

[0017] The first guide section of the guide track can have a beak-shaped, widening cross-section. This section can run essentially parallel to the storage surface along a boundary extending towards the storage surface and widen towards the clamping element on the side of the first guide section facing away from the storage surface. Because the second guide section runs parallel or at an angle to the axis of rotation, further rotation of the clamping element around the axis of rotation is blocked by the second guide section, allowing movement only parallel to the axis of rotation. This mechanically provides a simple and predetermined transition from the release position to the pre-clamping position and from the pre-clamping position to the clamping position.

[0018] In order to connect the actuator indirectly to the clamping element in a simple manner, it is advantageous if the actuating unit comprises at least one rod- or bar-like transmission element which is arranged at least partially in the housing, which is rotationally fixed to the actuating element and which has a transmission area which includes an external threaded section running around the axis of rotation, which is arranged on the side of the transmission element facing away from the clamping element and through which, during operation of the actuator, the actuating element can be moved at least parallel to the axis of rotation to move from the release position to the pre-clamping position and / or from the pre-clamping position to the clamping position.

[0019] Because the transmission element is rotationally fixed to the actuating element and connected to the actuator via a transmission area, the actuating element of the actuating unit is easily connected to the actuator.

[0020] The transmission element, with its transmission area comprising an external thread section, interacts with the actuator. This enables at least the movement of the transmission element parallel to the axis of rotation.

[0021] In a further development of the latter embodiment, the transmission element, when the actuator and the clamping element attached to it are moved from the release position to the pre-clamping position, can not only be moved parallel to the axis of rotation, but can also perform a rotational movement about the axis of rotation. Upon reaching the pre-clamping position, the guide unit then prevents the actuator and the transmission element, which is non-rotatably connected to the actuator, from further rotation. This ensures that the actuator is fixed against further rotation when moving from the pre-clamping position to the clamping position and performs a translational movement exclusively parallel to the axis of rotation towards the storage surface.

[0022] The actuator can, in principle, be of any design, provided that it interacts with the transmission range of the transmission element to adjust the actuating element.The locking device can be operated in a simple manner if the actuator has at least one worm gear, which has at least one rod-shaped worm element rotatably driven about a worm axis extending transversely or obliquely to the axis of rotation and which includes an external thread section in a transmission area, and which has at least one worm wheel which engages with the external thread section of the worm element with an external thread section and, in particular, engages with the external thread section of the transmission element of the actuating unit with an internal thread section, and / or if the actuator includes at least one actuating element comprising a receptacle, which can be actuated from the outside and by which the worm element can be rotated about the worm axis when actuated.

[0023] Because the actuator incorporates a worm gear, the actuating element can be easily positioned at any point on the clamping device for external actuation by a tool and / or an operator. This eliminates the need for access to the clamping element when moving it from the release position to the pre-clamping position and from the pre-clamping position to the clamping position.

[0024] In order to ensure relative movement of the transmission element to the worm gear and thereby to carry out the kinematics described above, it proves advantageous if the worm gear, in particular the worm element and the worm wheel, and / or if the actuating element, is arranged in the housing and is fixed against translational movement parallel and transverse to the axis of rotation.

[0025] This ensures that, during operation of the worm gear, the transmission element within the housing is moved relative to the housing, with the worm gear and the actuating element being essentially fixed in position.

[0026] It is conceivable to consider embodiments of the locking device in which the transmission element and the actuating element form a common one-piece component, or in which the transmission element and the actuating element comprise two separate or separable components that are connected to each other in a rotationally fixed manner with respect to the axis of rotation.

[0027] If the transmission element and the actuating element form a single, integral component, the locking device can be designed with fewer components. In this case, the transmission area is located on the side of the actuating element facing the storage surface. If the transmission element and the actuating element comprise two separate or separable components, further, additional functions of the locking device can be implemented. If the transmission element and the actuating element comprise two separate or separable components, it is advantageous for the actuating unit to include at least one anti-rotation device that secures the transmission element against rotation about the axis of rotation.

[0028] By providing an anti-rotation device, it can be ensured that the transmission element, when driven by the actuator, is moved almost exclusively parallel to the axis of rotation and is held against rotational movement.

[0029] The anti-rotation device can be provided at any point on the locking device. In one embodiment, the anti-rotation device comprises at least one continuous recess extending transversely to the axis of rotation in the actuating element, at least one recess extending transversely to the axis of rotation and open on one side, at least one continuous hole extending transversely to the axis of rotation in the transmission element, and at least one pin-like pin element that extends transversely to the axis of rotation through the at least one recess in the actuating element and the at least one hole in the transmission element, and that in particular has a cross-section that corresponds to, and in particular is complementary to, the cross-section of the at least one recess of the actuating element and that extends correspondingly to, and in particular is complementary to, an inner diameter of the hole of the transmission element extending transversely to the axis of rotation.

[0030] This allows the transmission element and the actuating element to be easily connected. When fixing the transmission element to the actuating element in a rotationally fixed manner, they are first positioned relative to each other so that they align perpendicular to the direction of rotation with at least one continuous recess and the continuous hole. In this case, the pin element is then inserted through both the at least one recess and the continuous hole in the transmission element.

[0031] The recess, which extends transversely to the axis of rotation and is open on one side, is also accessible from the direction of the cavity and / or opening.

[0032] In one embodiment of the fixing device, the pin-like pin element in the joined arrangement extends completely through the clamping element and transmission element in a plane transverse to the axis of rotation.

[0033] Because the pin-like pin element has a cross-section corresponding to, and in particular complementary to, the cross-section of the at least one recess of the actuating element, relative movement of the pin element within the recess of the actuating element is prevented or at least severely limited. The pin-like pin element can have a rounded, in particular circular, or polygonal, in particular 4-, 6- or 8-sided, cross-section.

[0034] As previously described, the anti-rotation device can be provided at any point on the locking mechanism. In a supplementary or alternative embodiment, the anti-rotation device comprises at least one groove extending parallel to the axis of rotation in the housing, particularly in the lower part of the housing, which is arranged on a side facing away from the actuator and which includes at least one pin-like pin element that can be detachably or permanently fixed to a free end of the transmission element facing away from the actuator, which projects laterally beyond the transmission element transversely to the axis of rotation and engages with at least one end in at least one of the at least one groove.

[0035] The groove can be located on the side of the housing facing the base, relative to the actuator. The same applies to the pin element, which is located on the side of the transmission element facing the base. The pin element can have a cross-section transverse to the axis of rotation that corresponds to, and in particular complements to, the cross-section of the groove. By engaging the pin element in the groove, the transmission element is held against rotation about the axis of rotation, but is free to move parallel to the axis of rotation.

[0036] It is conceivable to have embodiments in which two grooves are provided in the housing, which are opposite each other with respect to the axis of rotation, wherein the pin element projects beyond the transmission element transversely to the axis of rotation on two sides and engages in a groove with each end.

[0037] The locking device can include at least one stop in the housing that limits movement of the clamping element parallel to the axis of rotation towards the support surface when the clamping position is reached, wherein in the clamping position the actuating element, the transmission element and / or the clamping element bears against at least one of the at least one stop. Furthermore, the locking device can include at least one clamping element that acts between the transmission element and the actuating element and that clamps the clamping element fixed to the actuating element parallel to the axis of rotation towards the housing.

[0038] If the locking device includes at least one stop, the transition from the pre-clamping position to the clamping position may be limited by the stop. If a clamping element is provided between the actuating element and the transmission element, which clamps the clamping element fixed to the actuating element parallel to the axis of rotation towards the housing, a force acting on a storage body to be clamped is less rigid. In this case, it is possible to slightly displace the storage body by overcoming the clamping force of the clamping element.

[0039] In order to allow relative movement parallel to the axis of rotation between the actuating element and the transmission element, which are fixed to each other in a rotationally fixed manner, it proves advantageous if the hole in the transmission element, which extends transversely to the axis of rotation, comprises an elongated hole extending parallel to the axis of rotation, through the transmission element parallel to the axis of rotation relative to the pin-like pin element between a first stop position, in which the actuating element has a first distance to the support surface through the clamping element, and a second stop position, in which the actuating element, by moving against the clamping force of the clamping element, has a second distance to the support surface that is greater than the first distance.

[0040] The locking device can be designed to be compact if the actuating element of the actuating unit includes a cavity that is accessible at least from the direction of the base via an opening, wherein the rod- or bar-like transmission element is arranged at least sectionally in the cavity of the actuating element.

[0041] In such a case, the rod- or bar-like transmission element can be arranged at least sectionally within the actuating element.

[0042] In a further development of the latter embodiment, it proves advantageous if the actuating element comprises at least one coupling section which is arranged on the side of the actuating element facing away from the clamping element, which comprises the opening to the cavity of the actuating element and which has an inner diameter with respect to the axis of rotation which is smaller than the inner diameter of the cavity, in particular wherein the coupling section of the actuating element comprises at least on one side, in particular on both sides with respect to the axis of rotation, the recess of the anti-rotation device which extends transversely to the axis of rotation.

[0043] Finally, it proves advantageous if the actuating unit comprises at least one support element which is arranged in the cavity of the actuating element, which is fixed at the end of the transmission element opposite the actuator and which has an outer diameter transverse to the axis of rotation which corresponds, in particular complementary, to the inner diameter of the cavity, and if the clamping element of the actuating unit is arranged in the cavity of the actuating element, extends parallel to the axis of rotation through the transmission element and is supported in contact with both the coupling section of the actuating element and the support element.

[0044] Viewed perpendicular to the axis of rotation, the clamping element has a diameter larger than the diameter of the coupling section of the actuating element that encompasses the opening. This ensures that the clamping element is supported in contact with both the coupling section of the actuating element and the support element, which is fixed to the transmission element. When the actuating element moves relative to the transmission element, the distance between the coupling section and the support element decreases, thus compressing the clamping element. During this relative movement, the pin-like pin element moves from the first stop position in the elongated hole to the second stop position.

[0045] Further features, details and advantages of the invention will become apparent from the attached patent claims, the graphic representation and the following description of a preferred embodiment of the fixing device.

[0047] The figures show two embodiments of a fixing device, designated overall by reference numeral 2, for a fastening device for fixing a storage body to a storage surface 4 of a storage device. The fixing devices 2 each comprise a base 6, which is fixed directly or indirectly to the storage surface 4 of the storage device.

[0048] Furthermore, each of the fixing devices 2 comprises a housing 8 that is fixed to the base 6. In the embodiments of the fixing device 2 shown in the figures, the housing 8 comprises a lower housing part 10 that is fixed to the base 6 and an upper housing part 12 that is fixed to the lower housing part 10.

[0049] The fixing devices 2 also include a clamping element 14, which is arranged on a side of the housing 8 facing away from the base 6, outside the housing 8 and is movable relative to the housing 8.

[0050] Furthermore, the locking devices 2 comprise an actuating unit 16, which includes an actuating element 18 to which the clamping element 14 is fixed in a rotationally and positionally fixed manner relative to the actuating element 18, and which includes at least one actuator 20 by which the actuating element 18 and the clamping element 14 fixed thereto are moved from a release position ( Figure 1 ) can be converted into a pre-clamping position by rotating about a rotation axis 22 running transversely to the storage surface 4 ( Figure 2 ), in which the actuating element 18 and the clamping element 14 are rotated relative to the release position about the axis of rotation 22 and are fixed against further rotation about the axis of rotation 22 and are separated from the pre-clamping position by the actuating element 18 and the clamping element 14 ( Figure 2 ) by translational movement parallel to the axis of rotation 22 in the direction of housing 8 into a clamping position ( Figure 3) are transferable, in which the distance between clamping element 14 and storage surface 4 is reduced with respect to the pre-clamping position.

[0051] In the embodiments of the locking device 2 shown in the figures, the housing 8 comprises a housing cavity 24 in which the actuating element 18 is arranged at least section by section and the actuating element 18 with an outer surface section rotationally symmetrical with respect to the axis of rotation 22 abuts an inner surface section of the housing 8 rotationally symmetrical with respect to the axis of rotation 22, wherein the actuating element 18 is rotatable with respect to the axis of rotation 22 and movable parallel to the axis of rotation 22 relative to the housing 8.

[0052] To move the actuating element 18 and the clamping element 14 attached to it from the release position to the clamping position, a guide unit 26 is formed in the housing 8 and on the actuating element 18. This includes a groove-like receptacle 28 in the inner surface section of the housing 8, a recess 30 on the outer surface section of the actuating element 18, and a guide pin 32 engaging in the receptacle 28 and the recess, with a guide cam 30.

[0053] In the embodiments shown in the figures, the guide cam 30 comprising the receptacle 28 is formed by a first guide section 34 which runs transversely to the axis of rotation 22, which extends in particular parallel to the axis of rotation 22 in the direction of the clamping element 14 and which specifies the transfer of the actuating element 18 from the release position to the pre-clamping position.

[0054] Furthermore, the guide cam 30 formed by the recess includes a second guide section 36 into which the first guide section 34 leads and which runs parallel or obliquely to the axis of rotation 22, which blocks further rotation about the axis of rotation 22 and which specifies the transfer of the actuating element 18 from the pre-clamping position to the clamping position.

[0055] In the Figures 1 to 5 Figure 1 shows an embodiment of the locking device 2, in which the actuating unit 16 comprises a rod- or bar-like transmission element 38. The transmission element 38 is arranged at least partially within the housing 8. The transmission element 38 and the actuating element 18 are connected to each other in a rotationally fixed manner via an anti-rotation device 40.

[0056] The anti-rotation device 40 comprises at least one groove 74 extending parallel to the axis of rotation in the housing 8, in particular in the lower housing part 10, which is arranged on a side facing away from the actuating element 18 with respect to the actuator 20, and which comprises at least one pin-like pin element 46, which can be detachably or indetachably fixed or fixed to a free end of the transmission element 38 facing away from the actuating element 18, which projects laterally beyond the transmission element 38 transversely to the axis of rotation 22 and engages with at least one end in at least one of the at least one groove 74.

[0057] In the first embodiment of the fixing device according to Figures 1 to 5 The groove 74 is located on the side of the housing 8 facing the base 6, with respect to the actuator 20. The same applies to the pin element 46, which is located on the side of the transmission element 38 facing the base 6.

[0058] The pin element 46 has a cross-section transverse to the axis of rotation 22, which corresponds to, and in particular complements to, the cross-section of the groove 74. By engaging the pin element 46 in the groove 74, the transmission element 38 is held against rotation about the axis of rotation 22, but is free to move parallel to the axis of rotation 22.

[0059] In the Figures 1 to 5 In the illustrated embodiment, two grooves 74 are provided in the housing 8, which are opposite each other with respect to the axis of rotation 22, wherein the pin element 46 projects beyond the transmission element 38 transversely to the axis of rotation 22 on two sides and engages with each end in a groove 74.

[0060] Furthermore, the transmission element 38 includes a transmission area 58 on the side facing away from the support element 56, which comprises an external thread section. The transmission area 58 can be controlled by the actuator 20, allowing the transmission element 38 to rotate about the axis of rotation 22 and perform a translational movement parallel to the axis of rotation 22 towards the storage surface 4 when the actuator 20 is operated to move it from the release position to the pre-clamping position. Once in the pre-clamping position, the transmission element 38 can be moved by the actuator 20 in a purely translational movement parallel to the axis of rotation 22 towards the storage surface 4. This is because the transmission element 38 is rotationally fixed to the clamping element 14, and the clamping element 14 is fixed against further rotation about the axis of rotation 22 in the pre-clamping position by the guide unit 26.

[0061] In the embodiment shown in the figures, in particular in the Figures 1 to 3 as well as Figure 5 It is evident that the actuator 20 comprises a worm gear 60, which includes at least one rod-shaped worm element 62, which is rotatably driven about a worm axis 64 extending transversely or obliquely to the axis of rotation 22, and which includes an external thread section in a transmission area 66, and which has at least one worm wheel 68, which engages with the external thread section of the worm element 62 with an external thread section and engages with the external thread section of the transmission element 36 of the actuating unit 16 with an internal thread section.

[0062] Furthermore, the actuator 20 includes an actuating element 72 comprising a receptacle 70, which can be actuated from the outside and by which the worm element 62 can be rotated about the worm axis 64 when actuated.

[0063] Figure 6Figure 1 shows a detailed view of a second embodiment of the locking device 2, in which the actuating unit 16 comprises a rod- or bar-like transmission element 38. The transmission element 38 is arranged at least partially within the housing 8. The transmission element 38 and the actuating element 18 are connected to each other in a rotationally fixed manner via an anti-rotation device 40.

[0064] The anti-rotation device 40 comprises continuous recesses 42 extending transversely to the axis of rotation 22 in the actuating element 18, a recess 43 open on one side in the actuating element 18, a continuous hole 44 extending transversely to the axis of rotation 22 in the transmission element 38, and a pin-like pin element 46 which extends through both the recesses 42 and the hole 44.

[0065] In the embodiment of the locking device 2 shown in the figure, the anti-rotation device 40 is arranged in a coupling section 48 of the actuating element 18. An opening 50 is provided in the coupling section 48, through which a cavity 52 of the actuating element 18 is accessible from the outside. A clamping element 54 is arranged in the cavity 52, which is attached to the coupling section 48 of the actuating element 18 on one side. On the side opposite the coupling section 48, a support element 56 of the actuating unit 16 is provided, which is fixed to the transmission element 38 on the side opposite the actuator 20.

[0066] The hole 44 in the transmission element 38 comprises an elongated slot in which the pin-like pin element 46 is arranged in a first stop position in the embodiment shown in the figures. In the first stop position, the adjusting element 18 has a first distance to the support surface 4 due to the clamping element 54. The adjusting element 18 can be moved away from the support surface 4 in a direction parallel to the axis of rotation 22 by overcoming the clamping force until the pin-like pin element 46 can be arranged in a second stop position (not shown in the figures), in which the adjusting element 18 has a second distance that is greater than the first distance.

[0067] The following briefly explains the operating principle of the locking device 2: When the actuating element 72 is actuated, for example by a tool or manually, the worm element 62 is rotated about the worm axis 64, which runs transversely to the axis of rotation 22. The worm wheel 68 is driven to rotate about the axis of rotation 22 via the external thread section in the transmission area 66 of the worm element 62. The transmission element 38, which is arranged with its external thread section in the transmission area 58 in the internal thread section of the worm wheel 68, then rotates about the axis of rotation 22. The transmission element 38 is rotationally fixed to the actuating element 18, which is thereby also rotated about the axis of rotation 22 from the release position. Figure 1rotates. By rotating about the axis of rotation 22, the clamping element 14 rotates relative to the housing 8, thereby moving the guide bolt 32 along the first guide section 34 of the guide unit 26.

[0068] Upon reaching the pre-clamping position according to Figure 1 , the guide pin 32 reaches the second guide section 36 of the guide unit 26, which secures the actuating element 18 and the transmission element 38, which is non-rotatably connected to the actuating element 18, against further rotation about the axis of rotation 22. From reaching the pre-clamping position according to Figure 2 During further operation of the actuator 20, the transmission element 38 can only be moved parallel to the axis of rotation 22, thereby reducing the distance of the clamping element 14 with respect to the support surface 4. Upon reaching the clamping position according to Figure 3The clamping element 14, the actuating element 18 and / or the transmission element 38 are located at a stop on the housing 8, which limits further movement parallel to the axis of rotation 22 in the direction of the storage surface 4.

[0069] In order to loosen the clamping element 14 somewhat for moving and aligning the storage body, the adjusting element 18 can be moved in the direction away from the storage surface 4 against the acting clamping force of the clamping element 54, whereby the pin-like pin element 46 is moved within the elongated hole 44 relative to the transmission element 38.
