Description

TECHNICAL AREA

[0001] The present invention relates to a fastening system according to claim 1, a sanitary arrangement according to claim 10 and a method according to claim 12. STATE OF THE ART

[0002] It is known from the prior art to provide an inlet pipe in toilet bowls upstream of the inlet area. This inlet pipe is usually connected to a flushing elbow, which in turn is connected to a cistern via a water supply. PRESENTATION OF THE INVENTION

[0003] The present invention is based on the objective of providing a fastening system for attaching an inlet pipe to a sanitary article, which can be easily installed.

[0004] The device according to claim 1 solves these and other problems. Accordingly, a fastening system comprises a mounting bracket extending along a main axis with two spaced-apart bearing areas for engaging the sanitary article and a bearing point located between the two bearing areas, a holder with a bearing section by which the holder is supported in the bearing point of the mounting bracket, and with two bearing arms projecting away from the mounting bracket, which laterally limit a holder-side holding section, wherein an open passage is provided between the free ends of the two bearing arms, and an inlet pipe with a side wall that laterally surrounds a pipe section with a first pipe end and a second pipe end, and with a pipe-side holding section.

[0005] The pipe-side retaining section can be inserted during assembly via the passage into the holder-side retaining section, and the inlet pipe, when inserted, is engaged with the pipe-side retaining section and the holder-side retaining section.

[0006] The mounting system offers the advantage of very simple installation. In particular, the holder's positioning with the opening opposite the mounting bracket ensures that the inlet pipe is not completely enclosed by the holder. This eliminates the need for complicated gripping, as is the case with pipe clamps, for example. This is a significant advantage, especially when installing inside a toilet bowl where space is limited.

[0007] The passageway is located opposite the storage section and opposite the mounting bracket.

[0008] In a first variant, the two bearing sections are designed such that the inlet pipe, when inserted, is held with slight play relative to the holder. This means that the inlet pipe can move relative to the holder. In particular, a play can be provided that allows movement in the direction of the inlet pipe's central axis in the area of ​​the pipe-side holding section and / or movement perpendicular to the inlet pipe's central axis in the area of ​​the pipe-side holding section.

[0009] In a second variant, the two bearing sections are designed in such a way that the inlet pipe is held firmly to the holder when inserted.

[0010] Preferably, the bearing point on the mounting bracket is an opening in the mounting bracket. The bearing section is designed to fit the opening, with the bearing section projecting into the opening.

[0011] Preferably, the opening is arranged centrally between the two bearing areas when viewed in the main direction.

[0012] Preferably, the bearing point and the bearing section have locking features so that the bearing section can be locked to the bearing point. In a further first embodiment, the bearing point has a locking opening and the bearing section has a locking tab. The locking tab engages in the locking opening. In a further second embodiment, the bearing section has a locking opening and the bearing point has a locking tab. The locking tab engages in the locking opening.

[0013] The locking tab is preferably molded onto the bearing section.

[0014] Preferably, the mounting bracket is designed as a profile, the profile having a main web from which at least one side web extends, the side web being inclined at an angle to the main web. Particularly preferably, two side webs extend from the main web at a distance from each other, the mounting bracket having a U-shaped cross-section when viewed transversely to the main direction. Preferably, the locking opening is arranged at the transition from the main web to a lower side web. Preferably, the bearing point has an access opening in an upper side web. The bearing section projects into the profile through this access opening.

[0015] Preferably, the two bearing arms are integrally formed on the said bearing section and extend away from the bearing section.

[0016] Preferably, the mounting bracket and the holder each have at least one support surface by which the holder is supported on the mounting bracket.

[0017] Preferably, the support surface extends away from the bearing arms on both sides.

[0018] Preferably, the retaining section on the holder side has a rounded area that extends partially around the axis. Furthermore, the retaining section on the pipe side has a rounded area that extends partially around the central axis of the inlet pipe. When the inlet pipe is inserted, the two rounded areas are in full contact with each other.

[0019] The rounded areas ensure stable and secure storage of the inlet pipe in the holder.

[0020] Preferably, the rounded area of ​​the holder-side holding section extends over the bearing section and from the bearing section into the two bearing arms.

[0021] Preferably, the rounded area of ​​the holder-side holding section extends around the aforementioned axis at an arc angle of at least 200°. This ensures secure mounting.

[0022] Preferably, the holder-side retaining section and the pipe-side retaining section each have a first stop surface which, when the inlet pipe is inserted, are oriented towards each other or can be brought into contact with each other. These first stop surfaces form a first pair of stop surfaces. Furthermore, the holder-side retaining section and the pipe-side retaining section each have a second stop surface which, when the inlet pipe is inserted, are oriented towards each other or can be brought into contact with each other, forming a second pair of stop surfaces. These pairs of stop surfaces are arranged and oriented such that the inlet pipe is prevented from moving relative to the holder, particularly in the direction of the inlet pipe's central axis in the area of ​​the pipe-side retaining section.

[0023] In a particularly preferred embodiment, the inlet pipe has a stop surface projecting into the pipe cross-section inside the pipe section, wherein the stop surface can provide a stop for a flushing pipe projecting into the pipe section via the first pipe end, and wherein one of the aforementioned pipe-side stop surfaces is located on the outside opposite the stop surface arranged on the inside.

[0024] Preferably, the mounting bracket has two spaced-apart bearing receptacles for receiving a fastening rod, with the bearing point for the holder located between the two bearing receptacles.

[0025] Preferably, a gear unit is mounted in the aforementioned bearing housing, which can be brought into engagement with the mounting rod. The mounting rod is preferably a threaded rod.

DESCRIPTION OF PREFERRED EXECUTION FORMS

[0032] In the Figures 1 to 6A fastening system 1 according to a preferred embodiment of the present invention is shown. The fastening system 1 serves to fasten an inlet pipe 1 to a sanitary article S and to fasten the sanitary article S to a mounting structure, such as a mounting frame.

[0033] The fastening system 1 comprises a mounting bracket 2, a holder 5 mounted on the mounting bracket 2, and an inlet pipe 11, which in turn is mounted on the holder 5. The fastening system 1 is preferably used in a sanitary arrangement, as in the Figure 6 The fastening system 1 is shown in use. The fastening system 1 is stored in a rear-open interior space 33 in the sanitary article S.

[0034] The mounting bracket 2 extends along a main direction H. The mounting bracket 2 has two bearing areas 3. The bearing areas 3 are each 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, one bearing element 34 is arranged for each bearing area 3, which is shown in the Figure 2 and 6 As can be seen, the bearing element 34 is mounted on the bearing area 3, and the bearing area 3 is connected to the sanitary article S via the bearing element 34. In other variants, it is also conceivable that the bearing areas 3 are directly connected to the sanitary article S. Between the two bearing areas 3, the mounting bracket 2 has a bearing point 4 in which the holder 5 is mounted.

[0035] The training of the holder 5 is particularly dependent on the Figure 1The holder 5 has a bearing section 6, by which the holder 5 is supported in the bearing point 4 of the mounting bracket 2. Furthermore, the holder 5 has two bearing arms 7 projecting away from the mounting bracket 2. The bearing arms 7 laterally define a retaining section 8 on the holder side. An open passage 10 is provided between the free ends 9 of the two bearing arms 7. The inlet pipe 11 can be inserted into the holder 5 through this passage 10.

[0036] The inlet pipe 11 is formed with a side wall 12, which laterally surrounds a pipe section 13 with a first pipe end 14 and a second pipe end 15, as well as with a pipe-side retaining section 16. In the retaining section 16, the inlet pipe 11 extends along a central axis M. The inlet pipe 11 also has a deflection section 35 here.

[0037] The pipe-side retaining section 16, as mentioned above, can be inserted into the holder-side retaining section 8 via the passage 10. In the inserted state, the inlet pipe 11, with its pipe-side retaining section 16, engages with the holder-side retaining section 8 of the holder. The engagement can be such that the inlet pipe 11 is clamped between the two bearing arms 7 with respect to movement towards the aforementioned passage 10. In another embodiment, the engagement can be such that the inlet pipe 11 is not clamped with respect to movement towards the aforementioned passage 10, with an inner surface of the sanitary article then arranged to provide a stop for movement of the inlet pipe 11 through the passage 10. This is described in the Figure 4 symbolized by the line with the reference symbol X.

[0038] During assembly, the first step involves connecting the holder 5 to the mounting bracket 2. This is done in the Figure 2 shown. The unit consisting of holder 5 and mounting bracket 2 is then connected to the inlet pipe 11. Typically, the inlet pipe 11 is already connected to the sanitary fitting S before the unit is mounted. Figures 3 to 6 The diagrams show the mounted position. In the mounted position, the mounting bracket can be locked to the sanitary fitting.

[0039] The bearing point 4 on the mounting bracket 2 is an opening 17 in the mounting bracket 2. Here, the opening 17 extends as shown by the Figure 1 This is evident from the transition area between an upper web 36 and a main web 37, and partially extending into the upper web 36 and the main web 37. The bearing section 6 is shaped to fit the opening 17. In the assembled state, the bearing section 6 projects into the opening 17.

[0040] In the illustrated embodiment, the bearing point 4 and the bearing section 6 have locking structures 18, 19. The bearing section 6 can be locked to the bearing point 4 via the locking structures 18, 19. This enables a secure connection between the mounting bracket 2 and the holder 5. In the illustrated embodiment, the bearing point 4 has a locking opening 18 and the bearing section 6 has a locking tab 19. From the sectional view of the Figure 5 It is evident that the locking tab 19 engages in the locking opening 18. In the illustrated embodiment, the locking tab 19 abuts a locking edge 38 against a locking edge 39 on the locking opening 18.

[0041] The mounting bracket 2 and the holder 5 each have at least one support surface 20, 21, by which the holder 5 is supported on the mounting bracket 2. The support surface 20 on the mounting bracket 2 is provided by its upper web 36, and the support surface 21 on the holder 5 projects laterally from the holder 5 towards the bearing arms 7.

[0042] Of the Figure 1 and 2It is evident that both retaining sections 8, 16 have a respective rounded area 22, 23. The rounded area 22 on the retaining section 8 on the holder side extends partially around an axis A. In the illustrated embodiment, the rounded area 22 extends over the bearing section 6 and from the bearing section 6 into the two bearing arms 7. The retaining section 16 on the pipe side has a rounded area 23 which extends partially around the central axis M of the inlet pipe 11. When the inlet pipe 11 is inserted, the two rounded areas 22, 23 are in planar contact with each other.

[0043] In the illustrated embodiment, the rounded region 22 of the holder-side retaining section 8 extends around the aforementioned axis A by an arc angle of at least 200°. Preferably, the arc angle of the rounded region 22 of the holder-side retaining section 8 is smaller than the arc angle of the rounded region 22 on the pipe-side retaining section 16. However, the rounded region 22 is designed such that the holder 5 with the two bearing arms 7 engages at least half of the pipe-side retaining section 16. This engagement is shown in the sectional view of the Figure 4 visible.

[0044] The mounting carrier 2 also has a recess 41, which is preferably arranged in alignment with the rounded area 22 in the holder 5.

[0045] From the top view of the Figure 3The mounting of the pipe-side retaining section 16 within the holder-side retaining section 6 is shown. The holder-side retaining section 8 and the pipe-side retaining section 16 each have a first stop surface 24, 25. When the inlet pipe 11 is inserted, the two stop surfaces are oriented towards each other or can be brought into contact with each other. The two first stop surfaces 24, 25 form a first pair of stop surfaces. Furthermore, the holder-side retaining section 8 and the pipe-side retaining section 16 each have a second stop surface 26, 27, which, when the inlet pipe 11 is inserted, are oriented towards each other or can be brought into contact with each other, forming a second pair of stop surfaces.The aforementioned pairs of stop surfaces are arranged and oriented such that the inlet pipe 11 is prevented from moving relative to the holder 5, particularly in the direction of the central axis M of the inlet pipe 11 in the area of ​​the pipe-side retaining section 16, by the stop surfaces 24, 25, 26, 27. The stop surfaces 24, 25, 26, 27 can be positioned relative to each other such that the inlet pipe 11 is mounted in the holder 5 with or without play. In the illustrated embodiment, two first pairs of stop surfaces and one second pair of stop surfaces are arranged.

[0046] In the illustrated embodiment, the stop surfaces 24, 25 are inclined at an angle to the central axis M of the pipe section 13. However, the stop surfaces 24, 25 can also be formed at right angles to the central axis M of the pipe section 13.

[0047] Furthermore, the mounting bracket 2 has two spaced-apart bearing receptacles 28 for receiving a fastening rod, with the bearing point 4 for the holder located between the two bearing receptacles 28. A gear unit 40 is arranged in each of the two bearing receptacles 28.

[0048] In Figure 6The arrangement of the fastening system 1 on a sanitary article S is shown. The sanitary article S is in the form of a toilet bowl. The sanitary article S has an interior 33 accessible from the rear. In the interior 33, the sanitary article S has bearing receptacles 31 for receiving the bearing areas 3 of the mounting bracket 2. The mounting bracket 2 is positioned in the installed position of the sanitary article such that its main axis H is essentially horizontal. The sanitary article S has a water supply section 29 with a channel inlet 30. The inlet pipe opens into the channel inlet 30 of the water supply section 29 at its second pipe end 15.

[0049] The sanitary article S has a back side 32 and an interior space 33 accessible from the back side 32. The mounting bracket 2 lies completely and the inlet pipe 11 at least partially within the interior space 33.

[0050] A first method for assembling a sanitary arrangement according to the above description preferably comprises two steps. In a first step, the inlet pipe 11 is inserted into the sanitary article such that the second pipe end 15 opens into the channel inlet 30. In a second step, the mounting bracket 2 and the holder 5 are inserted into the interior 33 in their assembled state. During insertion, the holder-side retaining section 8 is connected to the pipe-side retaining section 16. The bearing areas 3 of the mounting bracket 2 engage in the bearing receptacles 31. Depending on the design of the bearing areas 3, an optional third step may involve providing a locking mechanism between the mounting bracket 2 and the bearing receptacle.

[0051] A second method for assembling a sanitary arrangement according to the above description preferably comprises two steps. In a first step, the mounting bracket 2, the holder 5, and the inlet pipe 11 are connected to one another. In a second step, the assembled mounting bracket 2, the holder 5, and the inlet pipe 11 are inserted into the interior. During insertion, the second pipe end 15 is pushed into the channel inlet 30, and the bearing areas 3 of the mounting bracket 2 are inserted into the bearing receptacles 31, thus engaging with the bearing areas 3. Depending on the design of the bearing areas 3, an optional third step may involve providing a locking mechanism between the mounting bracket 2 and the bearing receptacle. REFERENCE MARK LIST
