Description

Technical Field

[0001] The present invention relates to a fixation system according to claim 1, a sanitary device according to claim 10, and a method according to claim 12. Background Technology

[0002] As is known from the prior art, in toilets, an inlet pipe is installed in front of the inlet area. The inlet pipe is typically connected to a flush trap, which itself is connected to the flush tank. Summary of the Invention

[0003] The purpose of this invention is to provide a fixing system for securing an inlet tube to a sanitary product, which can be easily assembled.

[0004] This and other objectives are achieved through the subject matter of claim 1. Therefore, a fixing system comprises:

[0005] An assembly bracket extending along the main axis has two support areas positioned spaced apart from each other for engagement with a sanitary product, and a support portion located between the two support areas.

[0006] A retainer has a support section and two support arms extending away from the mounting bracket. The retainer is supported in a support portion of the mounting bracket by the support section. The two support arms laterally define the retainer section on the retainer side, wherein an open channel exists between the free ends of the two support arms.

[0007] as well as

[0008] An inlet pipe having a sidewall and a retaining section on the side of the pipe, the sidewall laterally surrounding a pipe section having a first pipe end and a second pipe end.

[0009] During assembly, the retaining section on the pipe side can be inserted into the retaining section on the retaining member side via the channel, and the inlet pipe engages with the retaining section on the retaining member side in the inserted state.

[0010] The advantage of the fixed system is that assembly is very simple. In particular, the arrangement of the retainer relative to the mounting bracket ensures that the inlet pipe is not completely surrounded by the retainer. This prevents complex wrapping, as is the case with pipe clamps. This is a significant advantage, especially when assembling in the confined space inside a toilet.

[0011] The channel is positioned opposite the support section and opposite the assembly bracket.

[0012] In the first variation, the two retaining sections are configured to hold the inlet pipe with a slight gap relative to the retainer in the inserted state. This means that the inlet pipe can be displaced relative to the retainer. In particular, a gap can be provided that allows movement along the central axis of the inlet pipe in the region of the retaining section on the pipe side and / or allows movement transversely to the central axis of the inlet pipe in the region of the retaining section on the pipe side.

[0013] In the second variation, the two retaining sections are configured to hold the inlet pipe fixedly relative to the retainer in the installed state.

[0014] Preferably, the support portion at the mounting bracket is an opening in the mounting bracket. The support section is configured to mate with the opening, wherein the support section extends into the opening.

[0015] Preferably, the opening is positioned at the center between the two support areas when viewed along the main direction.

[0016] Preferably, the support portion and the support segment have a locking structure, allowing the support segment to be locked to the support portion. In a further first variation, the support portion has a locking opening, and the support segment has a locking tab. The locking tab engages into the locking opening. In a further second variation, the support segment has a locking opening, and the support portion has a locking tab. The locking tab engages into the locking opening.

[0017] The locking tab is preferably formed at the support section.

[0018] Preferably, the mounting bracket is configured as a profile having a main web and at least one side web extending away from the main web, wherein the side web extends at an angle relative to the main web. Particularly preferably, the two side webs extend away from the main web at a distance from each other, wherein the mounting bracket has a U-shaped cross-section when viewed transversely in the main direction. Preferably, a locking opening is provided at the transition from the main web to the lower side web. Preferably, the support portion has an inlet opening in the upper side web. The support portion extends into the profile through this inlet opening.

[0019] Preferably, the two support arms are formed at the support section and extend away from the support section.

[0020] Preferably, the mounting bracket and the retainer each have at least one support surface, and the retainer is supported on the mounting bracket via the support surface.

[0021] Preferably, the support surface extends away from the support arm on both sides.

[0022] Preferably, the retaining section on the retainer side has a circular region that extends partially around the axis. Furthermore, the retaining section on the tube side has a circular region that extends partially around the central axis of the inlet tube. The two circular regions are in surface contact with each other when the inlet tube is inserted.

[0023] The circular area ensures stable and secure support for the inlet pipe within the retainer.

[0024] Preferably, the circular region of the retaining section on the retaining member side extends on the supporting section and extends from the supporting section into the two supporting arms.

[0025] Preferably, the circular region of the retaining section on the retaining member side extends at an arc angle of at least 200° around the axis. This provides secure support.

[0026] Preferably, the retaining section on the retainer side and the retaining section on the tube side each have a first stop surface, which are oriented relative to each other or can contact each other when the inlet tube is inserted. The first stop surfaces form a first stop surface. Furthermore, the retaining section on the retainer side and the retaining section on the tube side each have a second stop surface, which are oriented relative to each other or can contact each other when the inlet tube is inserted, and form a second stop surface. The stop surfaces are configured and oriented such that they prevent movement of the inlet tube relative to the retainer, particularly preventing movement of the inlet tube relative to the retainer along the central axis of the inlet tube in the region of the retaining section on the tube side.

[0027] In a particularly preferred embodiment, the inlet pipe has a stop surface inside the pipe section that extends into the pipe cross section, wherein the stop surface can provide a stop for a flushing pipe extending into the pipe section via a first pipe end, wherein one of the pipe-side stop surfaces is located on the outer side opposite to the stop surface provided on the inner side.

[0028] Preferably, the mounting bracket has two support receptacles positioned spaced apart from each other for accommodating the fixing rod, wherein the support portion for the retainer is located between the two support receptacles.

[0029] Preferably, the transmission units are supported in the support housings and can engage with the fixed rods. The fixed rods are preferably threaded rods.

[0041] Figure 6A cross-sectional view of a sanitary device having the fixed system shown in the foregoing figures is shown. Detailed Implementation

[0042] Figures 1 to 6 A fixing system 1 according to a preferred embodiment of the present invention is shown. The fixing system 1 is used to fix the inlet pipe 11 to the sanitary product S and to fix the sanitary product S to the assembly structure, such as the assembly frame.

[0043] The fixing system 1 includes an assembly bracket 2, a retainer 5 supported on the assembly bracket 2, and an inlet pipe 11 supported on the retainer 5. For example... Figure 6 As shown, the fixing system 1 is preferably used in a sanitary device. Here, the fixing system 1 is supported in a rearwardly open interior space 33 within the sanitary product S.

[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 arranged at the end sides of the mounting bracket 2. The support regions 3 are used to engage the mounting bracket 2 into the sanitary product S. In the illustrated embodiment, for this purpose, each support region 3 is provided with a support element 34, which... Figure 2 and Figure 6 As can be seen, the support element 34 is assembled at the support region 3, and the support region 3 is connected to the sanitary product S through or via the support element 34. In other variations, it is also conceivable that the support region 3 is directly connected to the sanitary product S. Between the two support regions 3, the mounting bracket 2 has a support portion 4, in which the retainer 5 is supported.

[0045] The structure of retainer 5 is particularly from Figure 1 As can be seen, the retainer 5 has a support section 6, which supports the retainer 5 in the support portion 4 of the mounting bracket 2. The retainer 5 also has two support arms 7 extending away from the mounting bracket 2. The support arms 7 laterally define the retaining section 8 on the retainer side. An open channel 10 exists between the free ends 9 of the two support arms 7. The inlet pipe 11 can be inserted into the retainer 5 through this channel 10.

[0046] The inlet pipe 11 is configured to have a sidewall 12 and a retaining section 16 on the pipe side, the sidewall laterally surrounding a pipe section 13 having a first pipe end 14 and a second pipe end 15. In the retaining section 16, the inlet pipe 11 extends along a central axis M. The inlet pipe 11 also has a turning section 35 here.

[0047] As described above, the retaining section 16 on the tube side can be inserted into the retaining section 8 on the retainer side via the channel 10. In the inserted state, the inlet tube 11 engages with the retaining section 8 on the retainer side of the retainer 5 via its tube-side retaining section 16. This engagement allows the inlet tube 11 to be clamped between the two support arms 7 regarding its movement relative to the channel 10. In another embodiment, the engagement allows the inlet tube 11 to be unclamped regarding its movement relative to the channel 10, wherein the inner side of the sanitary product is configured to provide a stop for the movement of the inlet tube 11 through the channel 10. This is in Figure 4 The symbol is represented by a line with the reference numeral X.

[0048] During assembly, in the first step, retainer 5 is connected to assembly bracket 2. This is in Figure 2 As shown in the diagram. Next, the unit consisting of the retainer 5 and the assembly bracket 2 is connected to the inlet pipe 11. Typically, the inlet pipe 11 is already connected to the sanitary product S before the assembly unit. Figures 3 to 6 The assembly position is shown. In the assembly position, the mounting bracket can be latched with the sanitary product.

[0049] The support portion 4 at assembly bracket 2 is the opening 17 in assembly bracket 2. Here, as... Figure 1 As shown, the opening 17 extends through the transition region between the upper web 36 and the main web 37 and partially extends into the upper web 36 and the main web 37. The support section 6 is configured in shape to match the opening 17. In the assembled state, the support section 6 extends into the opening 17.

[0050] In the illustrated embodiment, the support portion 4 and the support section 6 have locking structures 18 and 19. The support section 6 can be locked to the support portion 4 via the locking structures 18 and 19. This allows for a fixed connection between the mounting bracket 2 and the retainer 5. In the illustrated embodiment, the support portion 4 has a locking opening 18, and the support section 6 has a locking tab 19. Figure 5 As can be seen in the cross-sectional view, the locking tab 19 engages with the locking opening 18. In the illustrated embodiment, the locking tab 19 abuts against the locking edge 39 at the locking opening 18 with its locking edge 38.

[0051] The mounting bracket 2 and the retainer 5 each have at least one support surface 20, 21, via which the retainer 5 is supported at the mounting bracket 2. The support surface 20 at the mounting bracket 2 is provided by its upper web 36, while the support surface 21 at the retainer 5 extends laterally from the retainer 5 relative to the support arm 7.

[0052] from Figure 1 and Figure 2As can be seen, the two retaining sections 8 and 16 have corresponding circular regions 22 and 23. The circular region 22 at the retaining section 8 on the retaining member side extends partially around axis A. In the illustrated embodiment, the circular region 22 extends on the support section 6 and extends from the support section 6 into the two support arms 7. The retaining section 16 on the pipe side has a circular region 23, which extends partially around the central axis M of the inlet pipe 11. When the inlet pipe 11 is inserted, the two circular regions 22 and 23 are in surface contact with each other.

[0053] In the illustrated embodiment, the circular region 22 of the retaining segment 8 on the retainer side extends at an arc angle of at least 200° around the axis A. Preferably, the arc angle of the circular region 22 on the retainer side is smaller than the arc angle of the circular region 22 at the retaining segment 16 on the tube side. The circular region 22 is configured such that the retainer 5 wraps around at least half of the retaining segment 16 on the tube side with its two support arms 7. Figure 4 The cross-sectional view is visible.

[0054] The mounting bracket 2 also has a recess 41, which is preferably configured to align with the circular region 22 in the retainer 5.

[0055] from Figure 3 The top view shows that the retaining section 16 on the pipe side is supported in the retaining section 6 on the retainer side. The retaining section 8 on the retainer side and the retaining section 16 on the pipe side each have first stop surfaces 24 and 25. The two stop surfaces are oriented relative to each other or can contact each other when the inlet pipe 11 is inserted. The two first stop surfaces 24 and 25 form a first stop surface. Furthermore, the retaining section 8 on the retainer side and the retaining section 16 on the pipe side each have second stop surfaces 26 and 27, which are oriented relative to each other or can contact each other when the inlet pipe 11 is inserted, forming a second stop surface. These stop surfaces are configured and oriented such that the stop surfaces 24, 25, 26, and 27 prevent movement of the inlet pipe 11 relative to the retainer 5, particularly preventing movement of the inlet pipe 11 relative to the retainer 5 in the region of the retaining section 16 on the pipe side along the direction of the central axis M of the inlet pipe 11. Here, the stop surfaces 24, 25, 26, and 27 can be positioned relative to each other, so that the inlet pipe 11 is supported in the retainer 5 with or without clearance. In the illustrated embodiment, two first stop surfaces and one second stop surface are provided.

[0056] In the illustrated embodiment, the stop surfaces 24 and 25 are configured to be inclined at an angle relative to the central axis M of the pipe section 13. Alternatively, the stop surfaces 24 and 25 may be configured to be perpendicular to the central axis M of the pipe section 13.

[0057] Furthermore, the mounting bracket 2 has two support receptacles 28 positioned spaced apart from each other to accommodate the fixing rod, wherein the support portion 4 for the retaining member is located between the two support receptacles 28. The transmission unit 40 is respectively disposed in the two support receptacles 28.

[0058] Figure 6 The fixing system 1 is shown installed at the sanitary product S. Here, the sanitary product S is in the form of a toilet. The sanitary product S has an internal space 33 accessible from the rear. In the internal space 33, the sanitary product S has a support receiving portion 31 for accommodating a support area 3 for accommodating a 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 sanitary product S has a water guiding section 29 with a channel inlet 30. An inlet pipe extends into the channel inlet 30 of the water guiding section 29 at a second pipe end 15.
