Description

Field of the Invention

[0001] The present invention relates to a use of a hose for fluidly connecting a water outlet member to a valve on a sanitary fitting, wherein the water outlet member can be fixedly connected to the sanitary fitting.

[0002] The present invention further relates to a fluid arrangement for a sanitary fitting, the fluid arrangement including a water outlet member, a valve, and a hose fluidly connecting the water outlet member to the valve, wherein the hose is fluidly connected to a portion of the valve that faces away from the water outlet member in the use position of the valve.

[0003] The present invention further relates to a sanitary fitting. Background Art

[0004] It is known to use a hose in a sanitary fitting for the use described at the beginning. This enables the liquid guiding portion to be functionally separated from the mechanical support of the sanitary fitting, and thus provides a higher design freedom at the sanitary fitting. Summary of the Invention

[0005] The present invention is based on the task of simplifying the installation of a sanitary fitting.

[0006] To solve this task, the features of claim 1 are provided according to the present invention. In particular, therefore, according to the present invention, in the use of the type described at the beginning, it is proposed that the hose is guided without interruption and / or without additional components between the water outlet member and its valve-side end, and the hose extends in a section outside the housing that outwardly delimits the sanitary fitting.

[0007] Thus, the hose for changing the direction of return towards the valve can be formed outside the narrow space conditions of the housing. The uninterrupted guiding of the hose simplifies the installation. By omitting additional components, the installation of this structure is simplified, and the manufacturing cost or quantity of the components required therefor is reduced.

[0008] In particular, compared with the commutation achieved through an intermediate member, the uninterrupted guiding of the hose is advantageous because the number of possible unsealed parts of the hose guiding portion is reduced.

[0009] Further advantageously, the portion where the hose can be connected to the valve can be arranged such that visual inspection can be performed during installation and / or different hose lengths can be easily compensated.

[0010] Furthermore, it is advantageous that a hose that may already have a water outlet member installed at its end can be guided through the fitting housing from the water outlet side. Subsequently, the end to be connected to the valve can be guided through the fitting body with a greater degree of freedom of movement in order to connect it to the valve under visual inspection, and then the valve can be fixed to the fitting. For example, the support member can be installed last.

[0011] This can simplify the installation of the fluid arrangement structure, especially the valve, because installation activities in the narrow conditions within the fitting body can thus be avoided.

[0012] Therefore, the present invention particularly exerts its advantages in the case of fixed or fixable installation of the hose. In the case of fixed or fixable installation of the hose, the hose end at the water outlet is inaccessible from the outside during use.

[0013] According to another solution to the above-mentioned task, the features of claim 2 are provided according to the present invention. In particular, therefore, according to the present invention, in the use of the type described at the beginning, it is proposed that the hose extends in a section outside the housing that outwardly delimits the sanitary fitting between the water outlet and its valve-side end, and the hose is at least partially guided by a support member in this section.

[0014] In this way, it is possible to guide the hose outside the narrow space conditions of the housing in the area where the direction of the hose changes, so that the hose maintains a minimum radius in its commutation area. In this way, it is possible to avoid bending of the hose in the commutation area. Such a minimum radius can be, for example, greater than or equal to 20 millimeters. The danger when the hose is bent is that so-called white cracks may occur. This refers to a material change in the hose, which may especially cause crack formation or rupture of the hose when bent repeatedly.

[0015] By the defined guidance of the hose, it is possible to reduce the internal cross-sectional area of the remaining loops of the hanging hose. Therefore, the hose can be guided more compactly compared to this situation without a support member. In this way, especially when installing under a workbench or a kitchen sink, it is possible to prevent being clamped and / or hooked by, for example, a pushable drawer or a waste container. Thereby, the load on the hose can be reduced.

[0016] Here, it can be provided that the hose is guided without interruption in the area including the support member - especially between the water outlet and its valve-side end. This can simplify the installation. Additional hose couplings can be omitted.

[0017] Advantageous designs of the two already mentioned solutions to the task mentioned at the beginning are described in the dependent claims.

[0018] In an advantageous design, it can be provided that the hose is guided such that a change in the direction of the hose is achieved. Here, the guidance of the hose can especially be carried out by the support member and / or outside the housing that outwardly delimits the sanitary fitting. The change in direction can especially be a direction reversal, for example, a change in direction of more than 90°, especially 180°.

[0019] Thus, the direction change of the hose can be provided outside the sanitary fitting housing. Additionally, it is advantageous that the direction change is effected in a supported manner by a support member, such that hose kinking can be avoided.

[0020] In an advantageous design, it can be provided that two sections of the hose lead into the support member. The two sections of the hose leading into the support member preferably can extend parallel to one another. In particular, the sections of the hose can lead into a hose receiving portion of the support member.

[0021] Thereby, the hose can be guided more precisely in the region of the support member. The hose receiving portion can provide resistance against slipping of the support member on the hose. The hose sections leading into the support member can also diverge or converge. A plurality of hose receiving portions can also be configured.

[0022] In an advantageous design, it can be provided that the support member is implemented in multiple parts.

[0023] Thereby, the design freedom with respect to the support member can be increased. Thus, depending on the installation position of the hose, a favorable guidance of the hose can be selected. For example, the support member can be mounted on a hose that is already installed, wherein it can be dispensed with threading one of the ends of the hose into the support member.

[0024] In an advantageous design, it can be provided that at least two parts of the support member are connected to one another form - fitting, force - fitting, and / or material - fitting. In particular, the at least two parts of the support member can engage with one another.

[0025] In this way, a particularly detachable connection of the at least two parts of the support member can be achieved. In this way, the installation of the support member on the hose for the purposes of the present invention can be simplified.

[0026] In an advantageous design, it can be provided that the support member has a cut - out for receiving the hose. Alternatively or additionally, it can be provided that the support member has a cut - out for guiding the hose. In particular, the cut - out can be provided on one of the parts of the support member.

[0027] Thereby, the hose can be advantageously fixed and / or stabilized in or on the support member.

[0028] In an advantageous design, it can be provided that the support member is open towards one side. In particular, one of the parts of the support member can be open towards one side. Additionally, it can be provided that this is achieved such that a hose that is already installed at both ends can be inserted.

[0029] In this way, the installation according to the use of the present invention can be simplified. Instead of the hose having to be threaded through the support member, it can already be installed. The hose can be fixed in or on the support member after being placed in the support member. A retaining element can be used here to fix the hose.

[0030] In an advantageous design, it can be provided that the dividing line between two parts of the support member extends parallel to the extension direction of the hose within the support member.

[0031] Thereby, the hose can be stabilized by the above two parts of the support member in the course of its length extension. The extension direction of the hose within the support member can be seen from the outside.

[0032] In an advantageous design, it can be provided that the support member has a retaining element which fixes the hose to or in the support member. Alternatively or additionally, it can be provided that the support member has a retaining element which fixes at least two parts of the support member relative to one another.

[0033] In this way, different ways of fixing the hose to the support member can be achieved according to existing requirements, for example according to the type and material of the hose. For example, the hose can be placed in the support member and then fixed to the support member. The hose can also be placed between multiple parts of the support member which are fixed to one another. Combinations of these fixing options can also be achieved.

[0034] In an advantageous design, it can be provided that the retaining element is fixed within the outer boundary of the support member and / or within the housing of the support member.

[0035] In this way, a support member with a retaining element can be provided, and the hose only needs to be placed into the retaining element. During the insertion of the hose, the hose can deform the retaining element and fix itself in the support member. This further simplifies the installation. For example, a common retaining element can be provided to fix two sections of the hose.

[0036] In an advantageous design, it can be provided that the retaining element surrounds the hose in at least two cross-sectional areas. Alternatively or additionally, it can be provided that the retaining element surrounds the hose by means of at least one retaining claw. The retaining element can preferably be implemented as a surrounding one. For example, a surrounding retaining element can be located on the outer periphery of an opening of the support member. At least one retaining claw, preferably three retaining claws, can be provided for each cross-sectional area.

[0037] In an advantageous design, it can be provided that at least one retaining jaw of the retaining element is inserted into the hose. This insertion can preferably be carried out when the hose is subjected to a tensile load. Thus, at least one retaining jaw is inserted into the hose. In particular, this relates to at least one retaining jaw for each cross-sectional area of the hose. Thereby, the hose can be advantageously fixed by means of the retaining element. For example, the retaining element and / or the retaining jaw can be made of metal. The support member can be made of plastic, for example.

[0038] In an advantageous design, it can be provided that the connection structure of one end of the hose to the water outlet piece is implemented without a hose joint and / or without a pressure connection. Alternatively or additionally, it can be provided that the connection structure of one end of the hose to the valve is implemented without a hose joint and / or without a pressure connection. It can also be provided that both ends of the hose are realized without a hose joint and / or without a pressure connection.

[0039] In this way, the hose installation for realizing the use according to the invention can be further simplified.

[0040] To solve the above-mentioned task, according to the invention, alternatively or additionally, features of the claims for the fluid arrangement are provided side by side. In particular, therefore, according to the invention, in the fluid arrangement of the type described at the beginning, it is proposed that the use according to the invention is realized. In this way, the above advantages of the use according to the invention can be achieved in the fluid arrangement.

[0041] According to experience, to solve the above-mentioned task, alternatively or additionally, features of the claims for the sanitary fitting are provided side by side. In particular, therefore, according to the invention, in the sanitary fitting of the type described at the beginning, it is proposed that the use according to the invention is realized. Alternatively or additionally, it is proposed that the fluid arrangement according to the invention is realized.

[0042] Therefore, the above advantages of the use according to the invention or the fluid arrangement according to the invention can be utilized in the sanitary fitting.

[0043] It is further proposed that the use according to the invention is designed such that a fluid arrangement according to the invention is formed. Alternatively or additionally, in the use according to the invention, it is proposed that the fluid arrangement is formed as part of a sanitary fitting according to the invention.

[0044] In this way, the application fields of the use according to the invention, the fluid arrangement according to the invention and / or the sanitary fitting according to the invention can be further expanded.

[0045] Therefore, the various aspects described can be advantageously combined with each other.

[0071] Figure 2 Another sanitary fitting 100 according to the present invention is shown, in which the use according to the present invention of a hose 1 for fluidly connecting a water outlet member 2 to a valve 3 (not shown) on the sanitary fitting 100 is realized, wherein the water outlet member 2 can be fixedly connected to the sanitary fitting 100, and the hose 1 is guided continuously between the water outlet member 2 and its valve-side end 4, and the hose 1 extends in a section 5 outside the housing 6 that externally bounds the sanitary fitting 100 between the water outlet member 2 and its valve-side end 4, and the hose 1 is at least partially guided by a support member 7 in this section 5.

[0072] In Figure 1 and Figure 2 In the two embodiments shown, the hose 1 is guided such that a change in direction of the hose 1, i.e., a direction reversal, is realized.

[0073] In both cases, this guiding of the hose 1 is realized outside the housing 6 that externally bounds the sanitary fitting 100 and in Figure 2 the case of

[0074] Figure 3 is shown Figure 2 a perspective view of the support member 7 in

[0075] In Figure 4 it can be seen that two sections 8, 9 of the hose 1 lead into the support member 7. The sections 8, 9 of the hose 1 extend parallel to each other here and furthermore lead into a hose receiving portion 10 of the support member 7. The support member 7 is implemented in a multi-piece manner here and consists of two components 11, 12.

[0076] In Figure 5 it is possible to see, in particular, a connection site 13 between the components 11, 12 of the support member 7. Thus, the components 11, 12 of the support member 7 are connected to each other at least form-locked and force-locked, i.e., they engage with each other. In an embodiment not shown, the components 11, 12 of the support member 7 can be connected to each other materially locked.

[0077] The support part 7 (here the part 11) has a cutout 14 for receiving and guiding the hose 1.

[0078] Figures 6 to 9 Another embodiment of the sanitary fitting 100 according to the invention is shown, which has a hose 1 guided by means of a support part 7, wherein the support part 7 consists of a part 11 forming a hose receiving part 10 and a pin-shaped part 12, and the pin-shaped part is inserted into the part 12 and fixes the hose 1.

[0079] Figures 10 to 14 The embodiment of the sanitary fitting 100 according to the invention and the support part 7 shown in is different from the previous embodiment at least in the following: The support part 7 has a retaining element 16, which fixes the hose on and in the support part 7. In Figure 12 and its enlargement Figure 13 it can be seen that the retaining element 16 is fixed within the outer boundary 17 of the support part 7, that is to say within the housing 18 of the support part. Figure 13 The folding of the retaining claw 19 is shown, which holds the hose 1 in place at the retaining element 16 and the support part 7 by being embedded in the hose 1. This embedding of the retaining claw 19 occurs after the hose 1 has been introduced into the support part 7 with the retaining element 16, especially in the case where the hose 1 is subjected to a tensile load. In Figure 14 it can be seen that a total of six retaining claws 19 are implemented, which fix the hose 1 in the support part 7. Figure 14 It is also shown that the retaining element 16 is fixed in the support part 7 approximately up to half the wall thickness of the housing 18.

[0080] The retaining element 16 surrounds the hose 1 in at least two cross-sectional regions 20, 21, more precisely by means of at least one retaining claw 19, that is to say by means of at least one claw in each of the cross-sectional regions 20, 21, and more precisely by means of three claws 19 in the present embodiment.

The support part 7 or the only part 11 of the support part 7 is implemented open towards one side 22 here, so that the hose 1 already installed at both ends 4, 23 can be inserted. The hose receiving part 10 has an integrally connected retaining element 16 here.

[0082] Figures 19 to 22The difference between the embodiment shown and the previous embodiments lies at least in the following: The retaining element 16 is held against the housing 18 of the support member 7 on the outside, and at least two parts 11, 12 of the support member 7 are fixed relative to one another. The dividing line 15 between the two parts 11, 12 of the support member 7 extends parallel to the direction of extension of the hose 1 within the support member 7.

[0083] In all the embodiments shown, one end 4, 23, more precisely both ends 4, 23 of the hose 1 are connected to the water outlet member 2 and to the valve 3 in a hose - joint - free and crimp - free manner.

[0084] In the embodiment shown, furthermore, there is a fluid arrangement 50 for a sanitary fitting 100, which fluid arrangement has a water outlet member 2 and a valve 3 (not shown) and a hose 1 that fluid - connects the water outlet member 2 to the valve 3, wherein the hose 1 is fluid - connected to the part 24 of the valve 3 that faces away from the water outlet member 2 in the use position of the valve 3, and the use according to the invention is achieved. Thus, the fluid arrangement 50 is formed as part of the sanitary fitting 100.
