Description

[0001] Use of a hose for the fluidic connection of a spout with a valve on a sanitary fitting, fluidic arrangement and corresponding sanitary fitting

[0002] The invention relates to a use of a hose for the fluidic connection of an outlet piece to a valve on a sanitary fitting, wherein the outlet piece can be firmly connected to the sanitary fitting.

[0003] The invention further relates to a fluidic arrangement for a sanitary fitting, having an outlet piece and a valve and a hose which fluidically connects the outlet piece to the valve, wherein the hose is fluidically connected to a point on the valve which is remote from the outlet piece in the position of use of the valve.

[0004] The invention also relates to a sanitary fitting.

[0005] It is known to use hoses in sanitary fittings as described above. This makes it possible to functionally separate the fluid flow from the mechanical support of a sanitary fitting, thus creating greater design freedom for the sanitary fitting.

[0006] The invention is based on the object of simplifying the assembly of a sanitary fitting.

[0007] To achieve this object, the invention provides the features of claim 1. In particular, when used as initially described, the invention proposes that the hose be guided between the outlet piece and its valve-side end without interruption and / or without attachments and extend in a section outside the housing that defines the outwardly extending sanitary fitting.

[0008] This allows a change in the direction of the hose to return to the valve outside the confined

[0009] The housing's space requirements can be optimized. Uninterrupted hose routing simplifies assembly. Eliminating the need for add-on parts simplifies assembly of such a design, reducing manufacturing costs and the number of required parts.

[0010] The uninterrupted guidance of the hose is particularly advantageous compared to a deflection realized by an intermediate piece, since the number of places at which the hose guide could become leaky is reduced.

[0011] Another advantage is that a point at which the hose can be connected to the valve can be arranged in such a way that it can be seen during assembly and / or that different hose lengths can be easily compensated.

[0012] Another advantage is that it is possible to guide the hose, which may already have a mounted outlet piece at its end, from the outlet side through the fitting body. The end to be connected to the valve can then be guided through the fitting body with greater freedom of movement, allowing it to be connected to a valve under visual inspection, which can then be secured to the fitting. The support piece, for example, can be mounted at the end.

[0013] This can simplify the assembly of a fluidic arrangement, in particular the valve, since assembly activities under confined conditions within the valve body can be avoided.

[0014] The invention therefore reveals its advantages particularly in the case of permanently installed or installable hoses, where the hose end at the outlet piece is not accessible from the outside during use.

[0015] According to a further solution to the above-mentioned problem, the features of claim 2 are provided according to the invention. In particular, when used as described above, the invention proposes that the hose extends between the outlet piece and its valve-side end in a section outside the housing outwardly delimiting the sanitary fitting, and that the hose is guided at least partially by a support part in this section.

[0016] In this way, it is possible to guide the hose in the area of ​​its change of direction outside the confined space of the housing in such a way that the hose maintains a minimum radius in the area of ​​its deflection. This prevents the hose from kinking in the area of ​​the deflection. Such a minimum radius can be greater than or equal to 20 mm, for example. The danger of kinking the hose is that what is known as stress whitening can occur. This is a change in the material in the hose which, particularly if it is repeatedly kinked, could lead to cracking or bursting of the hose.

[0017] The defined hose routing makes it possible to reduce the inner cross-sectional area of ​​a remaining loop of the hanging hose. This allows the hose to be routed more compactly than would be the case without the support. This prevents pinching and / or snagging by, for example, sliding drawers or waste containers, particularly when installed beneath a worktop or kitchen sink. This reduces the strain on the hose.

[0018] In this case, it can be provided that the hose is guided without interruption in an area containing the support part, particularly between the outlet piece and its valve-side end. This can simplify assembly. Additional hose couplings can be eliminated.

[0019] Advantageous embodiments of the two solutions to the problem mentioned at the outset are described in the dependent claims.

[0020] In an advantageous embodiment, the hose can be guided in such a way that a change in direction of the hose is realized. The hose can be guided, in particular, through the support part and / or outside the housing that defines the outward boundary of the sanitary fitting. The change in direction can, in particular, be a reversal of direction, for example, a change of direction of more than 90°, in particular of 180°.

[0021] This makes it possible to arrange for the hose to change direction outside the housing of the sanitary fitting. It is also advantageous that the change in direction is supported by the support element, thus preventing the hose from kinking.

[0022] In an advantageous embodiment, two sections of the hose can be provided to open into the support part. The two sections of the hose opening into the support part can preferably run parallel to each other. In particular, the sections of the hose can open into a hose receptacle of the support part.

[0023] This allows the hose to be guided more precisely in the area of ​​the support member. The hose receptacle can provide resistance to displacement of the support member along the hose. The hose sections that lead into the support member can also diverge or converge. Multiple hose receptacles can also be provided.

[0024] In an advantageous embodiment, it can be provided that the support part is designed in several parts.

[0025] This allows for increased design freedom with regard to the support element. Depending on the hose's mounting position, a favorable hose routing can be selected. The support element can, for example, be mounted on an already installed hose, eliminating the need to thread one of the hose ends into the support element.

[0026] In an advantageous embodiment, at least two parts of the support member can be connected to one another in a force-fitting, form-fitting, and / or material-fitting manner. In particular, the at least two parts of the support member can be snapped together.

[0027] In this way, a particularly detachable connection of the at least two parts of the support member can be realized. The assembly of the support member to the hose for implementing a use according to the invention can be simplified in this way.

[0028] In an advantageous embodiment, the support part can be provided with a recess for receiving the hose. Alternatively or additionally, the support part can be provided with a recess for guiding the hose. In particular, the recess can be provided on one of the parts of the support part.

[0029] The hose can thus be advantageously fixed and / or stabilized in or on the support part.

[0030] In an advantageous embodiment, the support part can be open on one side. In particular, one of the parts of the support part can be open on one side. In addition, this can be implemented in such a way that the hose mounted at both ends can be inserted.

[0031] In this way, assembly for implementing a use according to the invention can be simplified. The hose does not need to be threaded into the support part, but can be pre-assembled. After being inserted into the support part, the hose can be fixed in or to it. A retaining element can be used to secure the hose.

[0032] In the advantageous embodiment, it can be provided that a dividing line between two parts of the support part runs parallel to the direction of travel of the hose within the support part.

[0033] The hose can thus be stabilized along its longitudinal extension by both of the support members. The direction of the hose's path within the support member can be recognized from the outside.

[0034] In an advantageous embodiment, the support part can be provided with a holding element that fixes the hose to or in the support part. Alternatively or additionally, the support part can be provided with a holding element that fixes at least two parts of the support part relative to one another.

[0035] In this way, depending on existing requirements, for example, depending on the type and material of the hose, various ways of securing the hose to the support part can be implemented. For example, the hose can be inserted into the support part and then secured to it. The hose can also be placed between several parts of the support part, which are then secured to one another. Combinations of these securing options can also be implemented.

[0036] In an advantageous embodiment, it can be provided that one or the holding element is fixed within an outer boundary and / or a housing of the support part.

[0037] In this way, a support part can be provided with a retaining element into which the hose simply needs to be inserted. During insertion, the hose can deform the retaining element and secure itself in the support part. This further simplifies assembly. For example, a common retaining element can be provided to secure both sections of the hose.

[0038] In an advantageous embodiment, it can be provided that one or the holding element encompasses the hose in at least two cross-sectional areas. Alternatively or additionally, it can be provided that one or the holding element encompasses the hose by means of at least one holding claw. The holding element can preferably be designed to be circumferential. The circumferential holding element can, for example, be located on an outer circumference of an opening in the support part. At least one holding claw, preferably three holding claws, can be provided for each cross-sectional area.

[0039] In an advantageous embodiment, at least one retaining claw of the retaining element can be provided to dig into the hose. This digging can preferably occur under tensile load on the hose. At least one retaining claw is thus dig into the hose.

[0040] In particular, this involves at least one retaining claw per cross-sectional area of ​​the hose. Thus, the hose can be advantageously secured by means of the retaining element. The retaining element and / or the retaining claws can be made of metal, for example. The support part can be made of plastic, for example.

[0041] In an advantageous embodiment, it can be provided that the connection of one end of the hose to the outlet nozzle is designed without a hose nipple and / or without crimping. Alternatively or additionally, it can be provided that the connection of one end of the hose to the valve is designed without a hose nipple and / or without crimping. It can also be provided that both ends of the hose are designed without a hose nipple and / or without crimping.

[0042] In this way, the assembly of the hose for realizing a use according to the invention can be further simplified.

[0043] To achieve the stated object, the invention provides, alternatively or additionally, the features of the independent claim directed to a fluidic arrangement. In particular, the invention proposes that a use according to the invention be realized in the fluidic arrangement of the type described above. In this way, the above-mentioned advantages of a use according to the invention in fluidic arrangements can be realized.

[0044] To achieve the stated object, experience has shown that the features of the independent claim directed to a sanitary fitting are provided alternatively or additionally. In particular, the invention proposes that a sanitary fitting of the type described above implement a use according to the invention. Alternatively or additionally, it is proposed that a fluidic arrangement according to the invention be implemented.

[0045] Thus, the above-mentioned advantages of a use according to the invention or a fluidic arrangement according to the invention can be utilized in sanitary fittings.

[0046] It is further proposed that a use according to the invention be designed such that a fluidic arrangement according to the invention is formed. Alternatively or additionally, in a use according to the invention, it is proposed that a fluidic arrangement be formed as part of a sanitary fitting according to the invention.

[0047] In this way, the field of application of inventive uses, inventive fluidic arrangements, and / or inventive sanitary fittings can be further expanded.

[0048] The individual aspects described can therefore be advantageously combined with one another.

[0077] Figure 1 shows a sanitary fitting 100 according to the invention in an axial section. In the sanitary fitting 100, an inventive use of a hose 1 for the fluidic connection of an outlet piece 2 to a valve 3 (not shown) on a sanitary fitting 100 is realized, wherein the outlet piece 2 can be firmly connected to the sanitary fitting 100, and wherein the hose 1 is guided between the outlet piece 2 and its valve-side end 4 without interruption and without attachments and extends in a section 5 outside the housing 6 delimiting the sanitary fitting 100 to the outside.

[0078] Figure 2 shows a further sanitary fitting 100 according to the invention, in which an inventive use of a hose 1 for the fluidic connection of an outlet piece 2 to a valve 3 (not shown) on a sanitary fitting 100 is realized, wherein the outlet piece 2 can be firmly connected to the sanitary fitting 100, and wherein the hose 1 is guided without interruption between the outlet piece 2 and its valve-side end 4, and wherein the hose 1 extends between the outlet piece 2 and its valve-side end 4 in a section 5 outside the housing 6 delimiting the sanitary fitting 100 to the outside, and wherein the hose 1 is guided at least partially by a support part 7 in this section 5.

[0079] In both embodiments shown in Figures 1 and 2, the hose 1 is guided in such a way that a change in direction, namely a reversal of direction, of the hose 1 is realized

[0080] In both cases, this guidance of the hose 1 is realized outside the housing 6 which delimits the sanitary fitting 100 to the outside and, in the case of Figure 2, also by the support part 7.

[0081] Figure 3 shows the support part 7 from Figure 2 in a perspective view, wherein it can be seen that two sections 8, 9 of the hose 1 open into the support part 7. The sections 8, 9 of the hose 1 run parallel and also open into a hose receptacle 10 of the support part 7. The support part 7 is designed in several parts and consists of two parts 11, 12.

[0082] In Figure 4, the curved course of the hose 1 through the support part 7 can be seen, wherein the hose 1 is guided in such a way that a change in direction, namely a reversal of direction of the hose 1, is realized.

[0083] Figure 5 particularly shows the connection point 13 between the parts 11, 12 of the support part 7. Thus, the parts 11, 12 of the support part 7 are connected to one another at least in a force-locking and form-locking manner, namely by snapping. In an embodiment not shown, the parts 11, 12 of the support part 7 can be connected to one another in a material-locking manner.

[0084] The support part 7, here the part 11, has a recess 14 for receiving and guiding the hose 1.

[0085] Figures 6-9 show a further embodiment of a sanitary fitting 100 according to the invention with a hose 1 guided by means of a support part 7, wherein the support part 7 consists of a part 11 forming the hose receptacle 10 and of a bolt-shaped part 12 which is inserted into the part 12 and fixes the hose 1.

[0086] The exemplary embodiment of the sanitary fitting 100 according to the invention and of the support part 7 shown in Figures 10-14 differs from the preceding exemplary embodiments at least in that the support part 7 has a holding element 16 which fixes the hose on and in the support part 7. In Figure 12 and its enlargement in Figure 13 it can be seen that the holding element 16 is fixed within an outer boundary 17, namely the housing 18 of the support part 7. Figure 13 shows a folding over of a holding claw 19 which holds the hose 1 in position on the holding element 16 and the support part 7 by digging into the hose 1. After the hose 1 has been inserted into the support part 7 with the holding element 16, this digging in of the holding claw 19 takes place in particular under tensile load on the hose 1. In Figure 14 it can be seen that a total of six holding claws 19 are provided, which fix the hose 1 in the support part 7.Figure 14 also shows that the holding element 16 is fixed in the support part 7 up to approximately half the wall thickness of the housing 18.

[0087] The holding element 16 encompasses the hose 1 in at least two cross-sectional areas 20, 21, specifically by means of at least one holding claw 19, namely at least one, and in this exemplary embodiment three, holding claws 19 in the cross-sectional areas 20, 21.

[0088] The exemplary embodiment of a sanitary fitting 100 according to the invention, shown in Figures 15-18, with a hose 1 and a support part 7, differs from the preceding exemplary embodiments at least in that the support part 7 is designed in one piece and consists of only one part 11. The support part 7, or the only part 11 of this support part 7, is open towards one side 22, so that the hose 1 mounted at both ends 4, 23 can be inserted. The hose receptacles 10 each have holding elements 16 connected as a single piece.

[0089] The embodiment shown in Figures 19 to 22 differs from the preceding embodiments at least in that the holding element 16 rests on the outside of the housing 18 of the support part 7 and fixes at least two parts 11, 12 of the support part 7 relative to one another. A dividing line 15 between the two parts 11, 12 of the support part 7 runs parallel to the direction of travel of the hose 1 within the support part 7.

[0090] In all the exemplary embodiments shown, the connection of one end 4, 23, and specifically both ends 4, 23, of the hose 1 to the outlet piece 2 and to the valve 3 is carried out without hose nipples and without crimping.

[0091] In the exemplary embodiments shown, there is also a fluidic arrangement 50 for a sanitary fitting 100 with an outlet piece 2 and a valve 3 (not shown) and a hose 1 which fluidically connects the outlet piece 2 to the valve 3, wherein the hose 1 is fluidically connected to a point 24 of the valve 3 facing away from the outlet piece 2 in the position of use of the valve 3, and wherein a use according to the invention is realized. The fluidic arrangement 50 is thus formed as part of a sanitary fitting 100.

[0092] Thus, the use of a hose 1 for the fluidic connection of an outlet piece 2 to a valve 3 on a sanitary fitting 100 is proposed, wherein the outlet piece 2 can be firmly connected to the sanitary fitting 100, and wherein the hose 1 is guided between the outlet piece 2 and its valve-side end 4 without interruption and / or without attachments and extends in a section 5 outside the housing 6 outwardly delimiting the sanitary fitting 100. Furthermore, the use of a hose 1 for the fluidic connection of an outlet piece 2 to a valve 3 on a sanitary fitting 100 is proposed, wherein the outlet piece 2 can be firmly connected to the sanitary fitting 100, and wherein the hose 1 is guided between the

[0093] Outlet piece 2 and its valve-side end 4 is guided without interruption, and wherein the hose 1 extends between the outlet piece 2 and its valve-side end 4 in a section 5 outside the housing 6 which outwardly delimits the sanitary fitting 100, and wherein the hose 1 is guided at least partially by a support part 7 in the section 5. In addition, a corresponding fluidic arrangement 50 and a corresponding sanitary fitting 100 are proposed.
