Description

TECHNICAL FIELD

[0001] The invention relates to a fixing system for sanitary articles according to claim 1. BACKGROUND

[0002] Fixing systems for fixing sanitary articles are known from the prior art.

[0003] From DE 20 2012 104 847 U1 a fixing element with a transmission is known. The fixing element has a housing from which fixing tabs project. Via these fixing tabs the housing can be connected with the transmission to a toilet bowl.

[0004] DE 20 2012 104 847 U1 is satisfactory in terms of ease of assembly. However, the manner of installation at the toilet bowl can in certain cases lead to an excessive installation space. SUMMARY

[0005] Starting from this prior art, it is an object of the invention to propose a fixing system for sanitary articles which is optimized in terms of the installation space required.

[0006] This object and others are achieved by a fixing system for sanitary articles according to claim 1. The fixing system therefore comprises an assembly bracket which extends along a main axis and has two bearing regions which are located at a distance from one another for engagement into a sanitary article, two transmission units each having a transmission housing and having a drive wheel which rotates about a first rotational axis and a driven wheel which rotates about a second rotational axis, wherein the rotational axes are angularly inclined at an angle to one another, and one fixing rod per transmission unit, which fixing rod is in engagement with the driven wheel, wherein the driven wheel is rotatable about the fixing rod when the drive wheel is operated. The assembly bracket has a bearing site for each transmission unit. Here, the transmission housing is supported in the respective bearing site.

[0007] By the transmission being supported via the transmission housing in the bearing site, the advantage of a compact structure is achieved. The transmission units and their transmission housings are located in the assembly bracket, which makes the overall arrangement more compact. A further advantage is that the transmission is surrounded by the assembly bracket, thus improving the stability of the fixing system.

[0008] It is particularly preferred that the two transmissions are identically configured. However, it is also conceivable that the two transmissions have different structural versions.

[0009] The engagement between the driven wheel and the fixed rod allows relative motion to occur between the fixed rod and the driven wheel as the driven wheel rotates. The fixed rod is preferably a threaded rod with external threads, and the driven wheel preferably includes a threaded nut with internal threads. The threaded nut can be separately formed from the driven wheel and connected to it in a rotationally inresistant manner. Alternatively, the threaded nut can be integrally formed on the driven wheel.

[0010] The angle between the two rotation axes is preferably 90°. The second rotation axis extends parallel to the central axis of the fixed rod.

[0011] The central axis of the fixing rod extends at an angle (specifically a right angle) relative to the main axis. In the installation position, the main axis and the central axis of the fixing rod are horizontal.

[0012] Toilets are the preferred choice for hygiene products.

[0013] Preferably, the support portion has two channel openings. The transmission unit can be installed through the first channel opening. The fixed rod extends through the second channel opening and is guided to the driven wheel.

[0017] Preferably, an additional opening is provided opposite to the first channel opening, wherein in the assembled state, the transmission housing preferably extends out of the mounting bracket through the additional opening.

[0018] Preferably, the first channel opening and the other opening are positioned offset from each other, such that the transmission housing is tilted at an angle relative to the mounting bracket, thereby positioning the first axis of rotation so that it is tilted at an angle relative to the main axis of the mounting bracket when viewed along the direction of the second axis of rotation.

[0019] Preferably, when viewed about the direction of the central axis of the fixed rod, the support and the transmission housing are completely located in the assembly bracket on the front and rear sides.

[0020] Preferably, the support portion has a support surface and a support tenon. The transmission unit has a support surface and a support groove. The two support surfaces are oriented relative to each other, and the support tenon engages with the support groove.

[0021] Preferably, the support surfaces extend parallel to each other. Preferably, the support surfaces extend at a 90° angle relative to the second axis of rotation.

[0022] Preferably, the support tenon and the support groove are oriented such that during assembly, the transmission housing must be moved in a direction extending parallel to the second axis of rotation or parallel to the central axis of the fixed rod to engage the support tenon into the support groove.

[0023] Preferably, during assembly, the transmission housing is inserted into the support portion through the channel opening in a direction perpendicular to the second rotation axis or perpendicular to the central axis of the fixed rod. Then, in order to support the engagement between the tenon and the support groove, the transmission housing is moved in the direction parallel to the second rotation axis or parallel to the central axis of the fixed rod.

[0024] Preferably, the support element is insertable into the gap between two support surfaces. In the inserted state, the support element fills the gap, causing the support tenon and the support groove to engage with each other.

[0041] Figure 6 The rear view of the fastening system combined with the sanitary products shown in the aforementioned figures is illustrated. Detailed Implementation

[0042] Figures 1 to 6 A preferred embodiment of the fixing system according to the present invention is shown. The fixing system 1 is used to fix a sanitary product S. In the drawings, the sanitary product S is shown as a toilet. The fixing system 1 is supported in the rearwardly open internal space 23 of the sanitary product.

[0043] The fixing system 1 includes an assembly bracket 2, two transmission units 4 supported on the assembly bracket 2, and a fixing rod 8 for each transmission unit 4.

[0044] The mounting bracket 2 extends along the main direction H. The mounting bracket 2 has two support regions 3. The support regions 3 are respectively provided at the end sides of the mounting bracket 2. The support regions 3 are used to engage the mounting bracket 2 with the sanitary product S. In the illustrated embodiment, each support region 3 is provided with a support element 25 for this purpose. The support element 25 is mounted at the support region 3, and the support region 3 is connected to the sanitary product S through or via the support element 25. In other variations, it is also conceivable that the support region 3 is directly connected to the sanitary product S.

[0045] In addition, the mounting bracket has two support portions 24, which are positioned spaced apart from each other. The support portions 24 are used to support the transmission housing 5.

[0046] The two transmission units 4 are identically configured. For example... Figure 1 As shown, the transmission unit 4 has a transmission housing 5, a drive wheel 6, and a driven wheel 7. The drive wheel 6 and the driven wheel 7 are supported in the transmission housing 5. The drive wheel 6 and the driven wheel 7 engage with each other via teeth. The drive wheel 6 can rotate about a first axis of rotation D1, and when the drive wheel 6 is operated accordingly, the driven wheel 7 rotates about a second axis of rotation D2. The two axes of rotation D1 and D2 are inclined relative to each other at an angle α. The angle α is preferably 90°. Preferably, viewed from the installation position, the first axis of rotation extends at an angle relative to the vertical direction, and the second axis of rotation extends parallel to the horizontal direction.

[0047] Each of the transmission units 4 is associated with one of the fixed rods 8. The fixed rod 8 engages with the driven wheel 7. When the drive wheel 6 is operated, the driven wheel 7 can rotate about the fixed rod 8. In the illustrated embodiment, a nut 26 is provided associated with the driven wheel 7, which is rotatably connected to the driven wheel 7. The fixed rod 8 has external threads, and the driven wheel 7 (the associated nut 26) has internal threads. When the drive wheel 6 is rotated, the driven wheel 7 rotates relative to the fixed rod 8. Figure 1 It can be seen that the drive wheel 6 and the driven wheel 7 can be inserted into the transmission housing 5 through the front opening 33.

[0048] As mentioned above, the transmission unit 4 is supported at the mounting bracket 2 and in the support portion 24. The transmission housing 5 of the transmission unit 4 is supported in the support portion 24.

[0049] In the illustrated embodiment, the mounting bracket is configured as a U-shaped profile. The U-shaped profile has a main web 21, and two side webs 22 extending away from the main web, the two side webs being positioned spaced apart from each other. The side webs 22 extend at an angle β relative to the main web 21. The angle β is preferably a right angle. The support portion 24 extends through the main web 21, the two side webs 22, and the spatial region defined by the main web 21 and the two side webs 22. The mounting bracket is preferably a formed metal profile.

[0050] The support portion 24 has a first channel opening 9. The transmission unit 4 can be installed into the first channel opening 9. The support portion 24 also has a second channel opening 10. The fixing rod 8 extends into the transmission unit 4 supported in the support portion 24 through the second channel opening 10, that is, into the driven wheel 7.

[0051] In the illustrated embodiment, a first channel opening 9 is provided in a first wall section 11 of the mounting bracket 2. Here, the first wall section 11 is provided by the side web plate 22. A second channel opening 10 is provided in a second wall section 12 of the mounting bracket 2. The second wall section 12 is provided by the main web plate 21. The wall sections 11 and 12, or the main web plate 21 and the side web plate 22, are positioned relative to each other such that the first channel opening 9 and the second channel opening 10 can enter from different directions.

[0052] In the illustrated embodiment, an additional opening 13 is provided at the mounting bracket 2. Here, the additional opening 13 is located at the side web 22 opposite to the side web 22 having the first channel opening 9. In the illustrated embodiment, in the assembled state, as... Figure 2 As shown, the transmission housing 5 extends upward and downward from the mounting bracket 2 through the first channel opening 9 and another opening 13. The transmission housing 5 does not extend from the second channel opening 10 when in the installed state. That is, referring to... Figure 2 The transmission housing extends upward and downward from the mounting bracket 2, but does not extend forward beyond the second wall section 11 or the front surface 27 of the main web 21.

[0053] from Figure 2 , Figure 3 and Figure 5 It can be seen that the first channel opening 9 and the other opening 13 are positioned offset from each other. This offset between the first channel opening 9 and the other opening 13 causes the transmission housing 5 to be angularly tilted relative to the mounting bracket 2 or its main axis H, or the first rotation axis D1 to be angularly tilted relative to the main axis H of the mounting bracket 2. The angle is denoted as δ. This can also be seen from... Figure 6 As can be seen, it has the following advantages: the tool W can be guided to the drive wheel 6 through a fixed opening in the sanitary product S.

[0054] The support portion 24 has a support surface 14 and a support tenon 15. Figure 4 The support surface 14 and the support tenon 15 are clearly visible. The transmission unit 4 has a support surface 16 and a support groove 17. The two support surfaces 14 and 16 are oriented relative to each other. The support tenon 15 engages with the support groove 17.

[0055] In the illustrated embodiment, the support element 18 is inserted into and fitted into the gap 19 between the two support surfaces 14, 16. In the inserted state, the support element 18 fills the gap 19, causing the support tenon 15 and the support groove 17 to engage with each other. Figure 1 The support element 18 is shown in a disassembled state. According to... Figure 4 As can be seen from the cross-sectional view, in the first step of assembly, the transmission unit 4 is installed into the support portion 24. Here, the transmission unit 4 is displaced along the rotation axis D2 of the driven wheel 7 or along the central axis M of the fixed rod 8, so that the support tenon 15 is positioned in the support groove 17. During this process, the two support surfaces 14 and 16 move away from each other, thereby forming the gap 19. Subsequently, the support element 18 can be installed into the gap 19 between the two support surfaces 14 and 16.

[0056] In the illustrated embodiment, as Figure 4 As shown, the support surface 16 of the transmission unit 4 is located at the driven wheel 7. Therefore, the driven wheel 7 rests against the support element 18. The support surface 16 of the transmission unit 4 is also, alternatively or additionally, part of the transmission housing 5.

[0057] The support element 18 is locked to the transmission housing 5 via a locking connector 20. For this purpose, the transmission housing 5 has at least one (two in this case) locking tab 28 that engages in corresponding locking bosses 29 formed at the support element 18.

[0058] Preferably, such as Figure 4 As shown, two support tenons 15 and two support grooves 17 are spaced apart from each other. Here, the upper support tenon 15 is provided by the upper web plate 22. The lower support tenon 15 is provided by the lower web plate 22. The support grooves 17 are spaced apart from each other at the transmission housing 5.

[0059] Furthermore, a receiving opening 30 is provided between the two support portions 24 to accommodate a bracket 31 for the inlet pipe 32. Here, the bracket 31 can be inserted into the receiving opening 30. The inlet pipe 32 can be connected to the bracket 31.

[0060] Figure 6The arrangement of the fixing system 1 at the sanitary product S is shown. Here, the sanitary product S has an internal space 23 accessible from the rear. Within the internal space 23, the sanitary product S has a support portion 33 for accommodating a support area 3 for the mounting bracket 2. In the installation position of the sanitary product S, the orientation of the mounting bracket 2 is positioned such that the main axis H is substantially horizontal. The transmission unit 4 can be operated via the aforementioned tool W. Here, the drive wheel 6 is driven, and then the drive wheel 6 drives the driven wheel 7.
