[0036] In the Figures 1 to 6A preferred embodiment of the fastening system according to the present invention is shown. The fastening system 1 serves to fasten a sanitary article S. In the figures, the sanitary article S is depicted as a toilet bowl. The fastening system 1 is mounted in a rearwardly open interior space 23 within the sanitary article.

[0037] The fastening system 1 comprises a mounting bracket 2, two gear units 4 mounted on the mounting bracket 2 and a fastening rod 8 for each gear unit 4.

[0038] The mounting bracket 2 extends along a main direction H. The mounting bracket 2 has two bearing areas 3. The bearing areas 3 are arranged at the ends of the mounting bracket 2. The bearing areas 3 serve to engage the mounting bracket 2 with the sanitary fitting. In the illustrated embodiment, a bearing element 25 is arranged for each bearing area 3. The bearing element 25 is mounted on the bearing area 3, and the bearing area 3 is connected to the sanitary fitting S via the bearing element 25. In other variants, it is also conceivable that the bearing areas 3 are directly connected to the sanitary fitting S.

[0039] Furthermore, the mounting bracket has two spaced-apart bearing points 24. The bearing points 24 serve to support the gearbox housing 5.

[0040] Both gear units 4 are identical in design. Gear unit 4 has, as shown by the Figure 1The figure shows a gearbox housing 5, a drive gear 6, and a driven gear 7. The drive gear 6 and the driven gear 7 are mounted in the gearbox housing 5. The drive gear 6 and the driven gear 7 mesh with each other via a toothed connection. The drive gear 6 is rotatable about a first axis of rotation D1, and the driven gear 7 is rotated about a second axis of rotation D2 when actuated by the drive gear 6. The two axes of rotation D1, D2 are inclined at an angle α, alpha to each other. The angle α, alpha is preferably 90°. In the installed position, the first axis of rotation is preferably inclined at an angle to the vertical, and the second axis of rotation is parallel to the horizontal.

[0041] Each of the aforementioned gear units 4 is associated with one of the aforementioned mounting rods 8. The mounting rod 8 engages with the output gear 7. When the drive gear 6 is actuated, the output gear 7 is rotatable about the mounting rod 8. In the illustrated embodiment, a nut 26 associated with the output gear 7 is arranged, which can be connected to the output gear 7 in a rotationally fixed manner. The mounting rod 8 has an external thread, and the output gear 7, here the associated nut 26, has an internal thread. When the drive gear 6 is rotated, the output gear 7 is rotated relative to the stationary mounting rod 8. Figure 1 It can be seen that the drive wheel 6 and the driven wheel 7 can be inserted into the gearbox housing 5 via a front opening 33.

[0042] As mentioned, the gear unit 4 is mounted in a bearing point 24 on the mounting bracket 2. The gear housing 5 of the gear unit 4 is mounted in the bearing point 24.

[0043] In the illustrated embodiment, the mounting bracket is designed as a U-profile. The U-profile has a main web 21 from which two spaced-apart side webs 22 extend. The side webs 22 are inclined at an angle β, beta to the main web 21. The angle β, beta is preferably a right angle. The bearing point 24 extends through the main web 21, through the two side webs 22, and through the space defined by the main web 21 and the two side webs 22. The mounting bracket is preferably a formed metal profile.

[0044] The bearing point 24 has a first access opening 9. The gear unit 4 can be inserted into the first access opening 9. The bearing point 24 also has a second access opening 10. The fastening rod 8 projects through the second access opening 10 into the gear unit 4, i.e., into the output gear 7, which is mounted in the bearing point 24.

[0045] In the illustrated embodiment, the first access opening 9 is arranged in a first wall section 11 of the mounting bracket 2. Here, the first wall section 11 is provided by the aforementioned side web 22. The second access opening 10 is arranged in a second wall section 12 of the mounting bracket 2. Here, the second wall section 12 is provided by the aforementioned main web 21. The wall sections 11 and 12, or the main web 21 and the side web 22, are positioned relative to each other such that the first access opening 9 and the second access opening 10 are accessible from different directions.

[0046] In the illustrated embodiment, a further opening 13 is arranged on the mounting bracket 2. This further opening 13 is located on the side web 22, which is arranged opposite the side web 22 with the first access opening 9. In the illustrated embodiment, the gearbox housing 5 protrudes in the assembled state, as shown by the Figure 2As can be seen, the first access opening 9 and the second opening 13 protrude upwards and downwards from the mounting bracket 2. The gearbox housing 5 does not protrude from the second access opening 10 when installed. This means that, with regard to the Figure 2 , that the gearbox housing protrudes upwards and downwards from the mounting carrier 2 and does not extend forwards over the front surface 27 of the second wall section 11 or the main web 21.

[0047] Of the Figures 2 , 3 and 5It is evident that the first access opening 9 and the further opening 13 are offset from each other. The offset between the first access opening 9 and the further opening 13 is such that the gearbox housing 5 is inclined at an angle to the mounting bracket 2 or to its main axis H, or that the first axis of rotation D1 is inclined at an angle to the main axis H of the mounting bracket 2. The angle is denoted by the reference symbol δ, delta. This is also evident from the Figure 6 evident and has the advantage that a tool W can be fed to the drive wheel 6 through a fastening opening in a sanitary article S.

[0048] Storage location 24 has a storage area 14 and a storage ridge 15. The storage area 14 and the storage ridge 15 are well protected from the Figure 4The gear unit 4 has a bearing surface 16 and a bearing groove 17. The two bearing surfaces 14 and 16 are oriented towards each other. The bearing collar 15 engages in the bearing groove 17.

[0049] In the illustrated embodiment, a bearing element 18 can be inserted into a gap 19 between the two bearing surfaces 14, 16 and is placed into this gap 19. The bearing element 18 fills the gap 19 in the inserted state, so that the bearing ridge 15 and the bearing groove 17 are engaged with each other. Figure 1 Bearing element 18 is shown in a disassembled position. From the sectional view according to the Figure 4It is evident that in the first step of assembly, the gear unit 4 is inserted into the bearing position 24. The gear unit 4 is then moved in the direction of the axis of rotation D2 of the output gear 7 or the central axis M of the mounting rod 8, so that the bearing boss 15 comes to rest in the bearing groove 17. This causes the two bearing surfaces 14 and 16 to move apart, creating the aforementioned gap 19. The bearing element 18 can then be inserted into the gap 19 between the two bearing surfaces 14 and 16.

[0050] In the embodiment shown, as described by the Figure 4 As can be seen, the bearing surface 16 of the gear unit 4 is arranged on the output gear 7. The output gear 7 thus rests against the bearing element 18. The bearing surface 16 of the gear unit 4 can alternatively or additionally also be part of the gear housing 5.

[0051] The bearing element 18 is locked to the gearbox housing 5 via a locking connection 20. For this purpose, the gearbox housing 5 has at least one, here two, locking tabs 28 which engage in one, here two, correspondingly designed locking cams 29 on the bearing element 18.

[0052] Preferably, as in the Figure 4 As can be seen, two bearing ridges 15 and two bearing grooves 17 are arranged at a distance from each other. Here, an upper bearing ridge 15 is provided by the upper side web 22. A lower bearing ridge 15 is provided by the lower side web 22. The bearing grooves 17 are spaced apart from each other on the gearbox housing 5.

[0053] Furthermore, a receiving opening 30 for a holder 31 for an inlet pipe 32 is arranged between the two bearing points 24. The holder 31 can be clipped into the receiving opening 30. The inlet pipe 32 can be connected to the holder 31.

[0054] In Figure 6The arrangement of the fastening system 1 on a sanitary fitting S is shown. The sanitary fitting S has an interior 23 accessible from the rear. Within the interior 33, the sanitary fitting S has bearing points 33 for receiving the bearing areas 3 of the mounting bracket 2. In the installed position of the sanitary fitting, the mounting bracket 2 is oriented such that its main axis H is essentially horizontal. The gear units 4 can be actuated using the tool W mentioned above. This drives the drive wheel 6, which in turn drives the output wheel 7. REFERENCE MARK LIST
