Description

[0040] In an exemplary and schematic manner

[0041] FIG. 1 shows a perspective view of a fastening device,

[0042] FIG. 2 shows a mounted fastening device in a suspended sanitary component,

[0043] FIG. 3 shows an integration of a fastening device in a sanitary component,

[0044] FIG. 4 shows a sectional view of a fastening device; and

[0045] FIG. 5 shows an embodiment of an adapter pin that is made integrally with the retaining bolt.

[0046] FIG. 1 shows a perspective view of a fastening device 1 for a sanitary component 2 to be suspended. In particular, an adapter pin 3 is shown here partially held (in a still open position) in a rotatable cam holder 8.

[0047] The adapter pin 3 is adapted to hold a retaining bolt 5 for the sanitary component at its first end 4. In particular, the adapter pin 3 is widened in the area of the first end 4 and has, for instance, a female threaded section for holding the retaining bolt 5. A widened retaining cam 7 is provided opposite at the second end 6. Since the adapter pin 3 and the retaining bolt 5 are used in conjunction to arrange the sanitary component 2 on a wall, they are designed to be coaxial to a mounting axis 10. Clamping or fastening is thus performed along the fastening motion 26, which is parallel to the mounting axis 10.

[0048] A rotatable cam holder 8 holds the second end 6, in particular having the widened retaining cam 7 of the adapter pin 3. The cam holder 8 can be rotated about an axis of rotation 11 oriented perpendicular to the mounting axis 10. One direction of rotation causes a locking motion 21, the opposite direction of rotation causes an opening motion 22 of the cam holder 8. In a section or centrally to the axis of rotation 11, the cam holder 8 is provided with a tool port, for instance for holding an Allen key.

[0049] The cam holder 8 is also provided with a recess 23, through which the second end 6 of the adapter pin 3 can be inserted laterally into the cam holder 8 together with the retaining cam 7. A gap 24 is formed adjacent to this recess 23, such that during a locking motion 21 this gap comprises the widened retaining cam 7 and, in that way, locks it in place. The gap 24 preferably extends (only) partially in the circumferential direction of the cam holder 8 and is then delimited by a stop. A contour 25 can also be provided on the inside, such that a fastening motion 26 is performed simultaneously with the locking motion 21 or opening motion 22.

[0050] Further, the cam holder 8 is designed having groove-like snap lugs 16 on the outer surface. These can be used to interact with adjacent components, particularly a mounting sleeve, when the fastening device is in the clamped state.

[0051] FIG. 2 shows a fastening device 1 integrated in a sanitary component 2. The sanitary component 2 has a shoulder 20, in which a passage 17 is provided. A retaining bolt 5 to be fastened to a wall 28 extends at least partially through this passage 17, by means of which securing bolt the sanitary component 2 is to be clamped against the wall 28.

[0052] A thread 27 is used to screw an adapter pin 3 onto this retaining bolt 5, such that they are interaligned along the mounting axis 10. The adapter pin 3, with a widened retaining cam 7, is arranged at the other end opposite from the thread 27.

[0053] A bipartite mounting sleeve 9 is provided in the passage 17 of the sanitary component 2, wherein the mounting sleeve 9 has a first mounting sleeve part 12 and a second mounting sleeve part 13. The first mounting sleeve part 12 has a male thread 27 at the (left) end, with which it is secured to the second mounting sleeve part 13. A first clamping collar 14 is provided at the opposite (right) end of the first mounting sleeve part 12. The second mounting sleeve 13 also has a second clamping collar 15 in the area of the thread 27. The thread 27 between the first mounting sleeve part 12 and the second mounting sleeve part 13 can be used to adjust the relative position of the first clamping collar 14 and the second clamping collar 15 to clamp the two clamping collars 14, 15 to the shoulder 20 of the sanitary component 2. This enables rough pre-assembly of the mounting sleeve 9 in the sanitary component 2.

[0054] The cam holder 8 is inserted into a lateral or radial aperture 29 of the second mounting sleeve part 13. In so doing, the arrangement is preferably such that an axis of rotation 11 of the cam holder 8 passes through a further orifice 18 of the sanitary component 2. A snap lug 16 can be provided opposite or on the underside of the cam holder 8, which permits it to be locked or centered there. When the sanitary component 2 with integrated mounting sleeve 9 and cam holder 8 is slipped over the adapter pin 3 including the retaining bolt 5, the widened retaining cam 7 engages with the cam holder 8. By rotating the cam holder 8, the cam holder 8 encompasses the retaining cam 7, locking it in place and applying a tensile force. In this way, the sanitary component 2 is moved towards the wall 28 and can be clamped against it.

[0055] FIG. 3 illustrates a section through a sanitary component 2 in the manner of a toilet bowl, wherein the relative position of the fastening device 1 to the sanitary component 2 is to be illustrated once again. A passage 17 is provided at the rear and along the mounting axis 10 for holding the retaining bolt or mounting sleeve 9. The mounting sleeve 9, which may be of bipartite design, can be pre-attached to a shoulder 20, which in particular forms the passage 17, of the sanitary component 2. The orientation of the axis of rotation 11 of the cam holder 8 is then preferably such that it can be reached or actuated through the further orifice 18. This orifice 18 can be provided, for instance, for securing another functional part 19, such as a toilet lid in this case.

[0056] As indicated for FIG. 2 above, a safety device can be provided in the mounting sleeve, in particular in the second mounting sleeve part 13, which can be used to prevent an unintentional opening motion of the cam holder 8. FIG. 4 shows a partial section of the mounting sleeve, wherein a groove (in a kind of counter contour) is arranged on the inside (i.e. not visible from the outside of the mounting sleeve), which can interact with a snap lug 16. The groove has a textured contour 25 resulting in a plurality of snap positions for the snap lug 16, impeding the motion towards the open position.

[0057] In addition to the above functions, there may be another advantage: The cam holder 8 is secured against falling out by two snap caps formed in the mounting sleeve 9 when mounted with the tool holder facing downwards.

[0058] FIG. 5 illustrates the situation where the adapter pin 3 comprises the retaining bolt 5, i.e., this is an integral embodiment. In other words, the retaining bolt 5 is molded directly onto the first end 4 of the adapter pin 3 made of the same material. In all other respects, reference is made to the above explanations.
