Description

[0001] PC 25 2483 C March 13, 2026

[0002] Hose assembly for a sanitary fitting, method for assembling a hose assembly and sanitary fitting

[0003] The invention relates to a hose arrangement for a sanitary fitting, comprising: a connection part, in particular a valve cartridge and / or an adapter part, a water outlet part, and a hose, as a fluidic connection between the water outlet part and the connection part.

[0004] The connection part can be a valve cartridge. Alternatively, the connection part can be an adapter part, with the adapter part being essentially positioned between a valve cartridge and the hose. In particular, it can be provided that the hose is inserted into the connection part.

[0005] The invention further relates to a method for mounting a hose assembly on a sanitary fitting and a sanitary fitting.

[0006] The object of the invention is to improve such hose assemblies for sanitary fittings. A further object of the invention is to improve such methods for mounting hose assemblies on sanitary fittings.

[0007] The object of the invention is solved by a hose arrangement having the features of claim 1.

[0008] According to the invention, the hose has at least one corrugated section. In the corrugated section, the hose is flexible enough that it can be bent even in tight radii without kinking or breaking. This simplifies the routing of the hose within a sanitary fitting.

[0009] In one embodiment, the hose can be bent to form a deflection in the corrugated section or in PC 25 2483 C 2 / 19 13 March 2026

[0010] Bent in the operating position. A deflection is common and necessary in hose arrangements to guide the hose from the valve cartridge to the outlet pipe. The advantage here is that the hose, in the corrugated section, can be bent into a deflection within a small radius, even inside the sanitary fitting.

[0011] This makes assembly simpler and more cost-effective.

[0012] In an alternative embodiment, the hose arrangement has a deflecting element connected to the hose, wherein the or a corrugated section is arranged between the deflecting element and the water outlet part.

[0013] In one design, the deflection in the operating position causes a change of direction by 180° and / or lies outside the sanitary fitting.

[0014] In one design, the corrugated section is located directly at the water outlet. This allows for a partially reliable installation of the water outlet at an angle.

[0015] In one embodiment, the sanitary fitting comprises a housing in which at least the connection part is arranged, and a spout pipe connected to the housing. It can be advantageous if the corrugated section is positioned in the area of ​​the transition from the spout pipe to the housing when in use. This transition point is usually characterized by an angle, so that a hose must have a bend here. Such a bend is easily achieved by the corrugated section without the hose kinking or being otherwise damaged.

[0016] In one embodiment, the hose has at least one first smooth section which is connected to the water outlet part, in particular wherein the water outlet part is connected to the first PC 25 2483 C 3 / 19 13 March 2026

[0017] The smooth hose section is permanently attached. This allows for a simple connection between the hose and the water outlet. The smooth section can, for example, be inserted into the water outlet, welded, or glued to it.

[0018] In one embodiment, the hose has at least a second smooth section that can be connected to or is connected to the connector. This also makes it easy to establish a connection between the hose and the connector.

[0019] In one version, the hose is made from a single piece. This allows for a simple and secure connection.

[0020] In an alternative design, the hose is multi-part, with the individual corrugated sections and smooth sections being designed as separate hose parts, each of which can be connected or joined together by hose couplings.

[0021] Regardless of whether the hose is a single piece or multi-piece, it can have alternating smooth and corrugated sections, with the smooth sections allowing it to be cut to length for connection to a hose coupling, connector, or water outlet. This allows the hose to be optimally adapted to various installation situations.

[0022] An alternative embodiment of a hose arrangement according to the invention comprises: a connection part, in particular a valve cartridge and / or an adapter part, a water outlet part, a deflecting element which is fluidically arranged between the water outlet part and the connection part, a first hose, as a fluidic connection between PC 25 2483 C 4 / 19 13 March 2026

[0023] The system comprises a water outlet section and a deflector element, and a second hose forming a fluidic connection between the deflector element and the connection section, characterized in that the first hose has at least one corrugated section. The corrugated section between the deflector element and the water outlet section allows the hose to bend at the connection point between a housing and an outlet pipe of a sanitary fitting. This simplifies assembly and prevents damage to the hose.

[0024] The invention further comprises a sanitary fitting with a housing in which at least the connection part is arranged, and a spout pipe connected to the housing, at the outlet of which a water outlet part is arranged, and with a hose arrangement according to the invention. Such a sanitary fitting is easy to install due to the hose arrangement. Furthermore, there is considerable freedom in the design of the sanitary fitting, since the corrugated sections of the hose allow for a high degree of variability.

[0025] In one embodiment, a first smooth section of the hose is arranged inside the outlet pipe, with the first smooth section projecting to the housing where it transitions into a first corrugated section. In this way, at least in the area at a connection point between the housing and the outlet pipe, there is a corrugated section that can be bent.

[0026] The invention further comprises a method for mounting a hose assembly on a sanitary fitting:

[0027] wherein a hose is connected at a soapy outlet end to a water outlet part,

[0028] the hose passes through an outlet opening of the PC 25 2483 C 5 / 19 13 March 2026

[0029] The sanitary fitting is led into the sanitary fitting.

[0030] wherein the hose is bent in a corrugated section to form a deflection or is connected to a deflection element, and

[0031] wherein a hose end on the connection part side and / or hose end on the joint part side is connected, in particular plugged in, to at least a part of a connection part, in particular a valve cartridge, and / or a joint part.

[0032] The invention further comprises a method for manufacturing a hose arrangement, wherein a connection part, in particular a valve cartridge and / or an adapter part, is fluidically connected to a water outlet part via a hose, characterized in that a first hose section is connected to the water outlet part, that a second hose section is connected to the first hose section and that the second hose section is connected to the connection part.

[0033] In one version, the length of the first hose section is adjusted to the length of a sanitary fitting's outlet pipe before it is connected to the second hose section.

[0034] In one version, the first hose section is designed as a smooth hose. This allows for easy connection to a connector or a water outlet.

[0035] In one embodiment, the second hose section has at least one corrugated section. At least one corrugated section allows for flexible routing of the hose within a fitting without causing damage to the hose. PC 25 2483 C 6 / 19 13 March 2026

[0036] In one version, the connection of the first hose section to the second hose section is made after the first hose section has been inserted into the outlet pipe of a sanitary fitting.

[0037] In one version, the connection of the second hose section to the first hose section takes place before the connection of the second hose section to the connecting part.

[0038] In one version, a hose coupling is formed on the downstream side of the second hose section. This allows, for example, a connection to a smooth hose section.

[0039] In one version, a fitting or a smooth section is formed on the inflow side of the second hose section. This allows for a connection to a fitting.

[0040] The invention is explained in more detail below with reference to exemplary embodiments and the accompanying drawings.

[0041] It shows:

[0047] Hose arrangement according to a further design in a first assembly step,

[0048] Fig. 6: a sectional view of the sanitary fitting with the hose arrangement from Fig. 4 in a second assembly step,

[0049] Fig. 7: a sectional view of the sanitary fitting with the hose arrangement from Fig. 4 in a third assembly step and

[0050] Fig. 8: a cutaway three-dimensional view of Fig. 6.

[0051] Fig. 1 shows a sectional view of a sanitary fitting 1 with a hose arrangement 2 according to a first embodiment.

[0052] The design of the sanitary fitting 1 is irrelevant to the invention, which is why the sanitary fitting 1 is shown here only as an example. The sanitary fitting 1 has a housing 3 with an outlet pipe 4.

[0053] The hose arrangement 2 comprises a connection part 5, which is designed as an adapter part 6, a water outlet part 7, and a hose 8, as a fluidic connection between the water outlet part 7 and the connection part 5.

[0054] The water outlet part 7 is designed, for example, to accommodate a flow regulator (not shown) and is arranged at the free end of the outlet pipe 4.

[0055] In this example, the adapter part 6 is shaped approximately like a cup. Two water supply hose connections 9 and one mixed water hose connection 10 are arranged on the adapter part 6. Hoses 30 are attached to the water supply hose connections 9, each leading, for example, to an angle valve.

[0056] Hose 8 is connected at one end 12 to the water outlet part 7. For this purpose, hose 8PC 25 2483 C 8 / 19 13 March 2026 can be used.

[0057] For example, the hose 8 may be welded or glued to the water outlet part 7. The hose 8 may also be inserted into the water outlet part 7 or otherwise detachably connected to it. However, the type of connection is irrelevant to the invention.

[0058] At its second end 13, the hose 8 has a connecting part 14 with which the hose 8 can be connected or is connected to the mixed water hose connection 10 of the adapter part 6.

[0059] In this version, the mixed water hose connection 10 has an internal thread 11 and the hose 8 has a corresponding external thread (not shown), so that the connecting part 14 can be screwed into the mixed water hose connection 10.

[0060] The adapter part 6 is inserted into a receiving chamber 15 of the housing 3 and itself forms a cartridge chamber 16 into which a valve cartridge 17 is inserted. In the exemplary embodiment, a cartridge adapter 18 is also arranged at the bottom of the cartridge chamber 16, which connects the connections of the valve cartridge 17 to the hose connections 9 and 10 of the adapter part 6. The cartridge adapter 18 makes it possible to use one adapter part 6 with different valve cartridges 17. In this way, a cost-effective and variable design of the hose arrangement is possible.

[0061] The adapter part 6 seals against the receiving chamber 15 of the sanitary fitting 1 by means of a radial seal 19, which is arranged on the upper, open circumference of the adapter part 6.

[0062] Hose 8 is essentially pressure-resistant, both against water pressure and in the longitudinal direction of the hose. This means that the hose does not deform under axial pressure and thus, for example, simply PC 25 2483 C 9 / 19 13 March 2026

[0063] can be inserted, for example, into the water outlet part 7.

[0064] In this embodiment, the hose 8 has two corrugated sections 20. These corrugated sections 20 are characterized by the fact that the hose 8 can be easily deformed, for example bent, without kinking or breaking. The corrugated sections 20 are designed approximately as a corrugated hose or tube. For the sake of simplicity, the non-corrugated sections of the hose are referred to below as smooth sections 21.

[0065] The hose 8 can be manufactured in one piece, with smooth sections 21 and corrugated sections 20 alternating.

[0066] However, the smooth sections 21 and corrugated sections 20, or at least some of them, can also be separate hose sections that are permanently and firmly joined together. For this purpose, the sections can be glued or welded together, or connected by push-fit connectors.

[0067] However, the position of the corrugated sections 20 within the sanitary fitting 1 is important and decisive. A first corrugated section 22 connects directly to the adapter part 6. This first section 22 is bent in such a way that it forms a deflection 23 which redirects the water flow by 180°.

[0068] A second corrugated section 24 is located at the connection point 25 between the housing 3 and the outlet pipe 4 of the sanitary fitting 1. The second corrugated section 24 forms a bend 27 that is curved around the sharp edge 26 of the connection point 25. This prevents damage to the hose 8 by this sharp edge 26. Furthermore, it prevents kinking of the hose 8, which is particularly likely at acute angles between PC 25 2483 C 10 / 19 13 March 2026

[0069] Outlet pipe 4 and housing 3 could come into contact. In the example, the angle of the bend is 27 90°, although other angles are possible depending on the design of the sanitary fitting.

[0070] Overall, the two corrugated sections of hose 8 enable and simplify the assembly of hose arrangement 2 in various sanitary fittings.

[0071] For assembly, the hose 8 is preferably first connected to the water outlet part 7 outside the sanitary fitting 1. Depending on the design, a connecting part 14 can also be attached to the other end of the hose.

[0072] The hose 8 is then inserted through the outlet opening 26 of the outlet pipe 4 into the sanitary fitting and the water outlet part 7 is finally placed in the outlet opening.

[0073] The hose 8 can be inserted into the housing 3 of the sanitary fitting 1 by bending the corrugated sections 20 and initially led out of the housing 3 in the opposite direction to the adapter part 6. Then, the deflection 23 can be formed in the first corrugated section 22 and the connecting part 14 can be connected to the adapter part 6, for example by pushing it together.

[0074] Fig. 2 shows another embodiment of a hose assembly 2 in a sanitary fitting 1, where only the differences to Fig. 1 are explained in more detail. Identical components are generally provided with the same reference numerals.

[0075] In this embodiment, hose 8 has only a single corrugated section 20. In this example, this extends almost over the entire length of hose 8, with only one corrugated section at each of the two ends of hose 8. PC 25 2483 C 11 / 19 13 March 2026

[0076] A smooth section 21 is present. The corrugated section 20 forms the deflection 23 and bend 27.

[0077] In this example, the connecting part 14 is also designed as a push-fit connector into which a smooth section 21 of the hose 8 is directly inserted. The mixed water hose connection 10 therefore has a smooth inner wall and no internal thread. Fig. 3 shows this push-fit connector and the bend 27 in detail.

[0078] Fig. 4 shows another embodiment of a hose arrangement 2 in a sanitary fitting 1, where again only the differences to Fig. 1 are explained in more detail.

[0079] Hose 8 has only one corrugated section 20, which forms the bend 27. Hose assembly 2 has a further deflection 23, formed by a separate deflection element 28. Hose 8 is connected to the deflection element 28 via a push-fit connection with a smooth section 21. Another hose 29 connects the deflection element 28 to the adapter part 6. Hose 29 is also connected to the deflection element 28 via a push-fit connection. On the valve side, hose 29 has a connecting part 14, which is screwed into the adapter part 6. However, the type of connection between hose 8 and adapter part 6 is fundamentally irrelevant to the invention.

[0080] Figures 5 to 8 show another embodiment of a hose arrangement 2 in a sanitary fitting 1, where again only the differences to Figure 1 are explained in more detail.

[0081] The hose assembly 2 here has an adapter part 6 in which a mixed water hose connection 10 is arranged laterally. This eliminates the need for a bend in the hose 8 at the connection point 25 between the outlet pipe 4 and the housing 3. The hose 8 has a corrugated PC 25 2483 C 12 / 19 13 March 2026

[0082] Section 20, which lies inside the outlet pipe 4 and can be used here to compensate for the length of the hose 8 during assembly.

[0083] In Fig. 5, the connecting part 5 is still separated from the hose 8. The drawing shows the situation after the hose 8 with the attached water outlet part 7 has been inserted through the outlet opening 26 into the outlet pipe 4.

[0084] Now, as shown in Fig. 6, the connecting part 5 (or alternatively a cartridge) is placed onto the free end of the hose 8.

[0085] Finally, as shown in Fig. 7, the connecting part 5 (or alternatively the aforementioned cartridge) with the inserted hose 8 is inserted into the receiving chamber 15. The excess length of the hose 8 is accommodated in the at least one corrugated section 22, for example by meandering and / or by compression.

[0086] The connection part 5 can generally have at least one water hose connection 31, preferably at least two water hose connections 31.

[0087] A hose assembly 2 according to the invention for a sanitary fitting 1 thus comprises at least: a connection part 5, in particular a valve cartridge 17 and / or an adapter part 6, a water outlet part 7, and a hose 8, as a fluidic connection between the water outlet part 7 and the connection part 5. The hose 8 has at least one corrugated section 20, 22, 24. Fig. 1
