Description

Sanitary interface, use thereof, modular kit for producing same, sanitary fitting

Technical Field

The invention relates to a sanitary fitting for connecting two liquid-conducting connecting elements, to a sanitary fitting, to a modular kit for producing a sanitary fitting, and to the use of a sanitary fitting in a water-conducting part of a sanitary fitting.

Background

A sanitary connection of the generic type comprises two fluid-conducting connecting elements which, in the position of use, are connected to one another and form a fluid line which is sealed off from the outside, and the second of the two connecting elements is designed or arranged on the end of the hose.

The same type of sanitary interface is disclosed in practice in a different embodiment.

Disclosure of Invention

The object of the present invention is to provide a sanitary interface of the type mentioned at the outset with improved use properties.

In order to solve this problem, a sanitary fitting of the type mentioned at the outset is initially proposed, which has a first liquid-conducting connecting element and a second liquid-conducting connecting element, which are connected to one another in the use position and form a liquid line which is sealed off from the outside, and which is formed or arranged on the hose end, characterized in that the liquid line is sealed at the connection point between the first connecting element and the second connecting element by an axial seal, and the first connecting element is formed or arranged on the sanitary function. The functional element can be, for example, a water outlet element and/or a jet regulator for a sanitary fitting.

In one embodiment of the sanitary interface, it is provided that the axial seal is designed as an unreleasable axial seal. In order to form an axial seal, in particular a non-releasable axial seal, the first connecting element and the second connecting element can be connected to one another in a material-locking manner. The material-locking connection for forming the axial seal between the first connecting element and the second connecting element can be produced, for example, by laser welding, ultrasonic welding and/or friction welding.

In order to solve this problem, a sanitary connection of the type mentioned at the outset is also proposed, which has a first liquid-conducting connecting element and a second liquid-conducting connecting element, which are connected to one another in the use position and form a liquid line which is sealed off from the outside, and which is formed or arranged on the hose end, characterized in that the liquid line is sealed off at the connection point between the first and the second connecting element by a releasable axial seal. As releasable axial seal, for example, a releasable axial sealing ring can be used.

By sealing the connection between the first connection element and the second connection element using an axial seal, both types of sanitary interfaces can be installed particularly simply.

The axial seal is further characterized by a reliable and loadable sealing action.

In one embodiment of the aforementioned sanitary fitting, it is provided that one of the two connection elements is designed as a hose or a hose nipple. In sanitary connections with a connecting element in the form of a hose nipple, the hose connected to the hose nipple and the hose nipple can be made of the same material and/or be integrally formed or of course also of different materials.

In one embodiment of the sanitary joint, it is provided that at least one of the two connection elements is designed as a spout or is designed or arranged on the spout. Preferably, at least one of the two connecting elements is designed as a water outlet for the sanitary fitting or is arranged or designed on the water outlet. The outlet member may be a water outlet member without a hose nipple.

In addition, the above-mentioned outlet piece can be made of a different material than, for example, the above-mentioned hose and/or be designed as, for example, the above-mentioned hose nipple.

In one embodiment of the sanitary fitting, it is provided that the connection direction for connecting the first connection element and the second connection element extends transversely, in particular perpendicularly, to the throughflow direction of the liquid through the liquid line. The installation of the sanitary fitting can be further simplified by the connection direction defined in this way. Even in the case of small installation spaces, installation is possible. In order to reach the connection position of the two connection elements, the path which the two connection elements have to pass through relative to each other can also be particularly short in the connection direction, which is transverse, in particular perpendicular, to the throughflow direction of the liquid through the liquid line.

The use of an axial seal for sealing the connection point between the first connecting element and the second connecting element also contributes to the simplest possible installation of the sanitary joint.

In one embodiment of the sanitary interface, it is provided that at least one of the connection elements has at least one fastening element, which can be connected to a mating fastening element of the sanitary fitting, which fastening element is adapted to the fastening element. In this way, at least one of the two connecting elements can be fastened on or in the sanitary fitting. This embodiment of the sanitary interface is advantageous, in particular, when the at least one aforementioned connecting element is configured as a water outlet for a sanitary fitting.

A particularly comfortable and also reliable connection of the two connecting elements is possible when the connection between the two connecting elements is configured as an insertion-rotation connection. The connection between the two connecting elements can also be configured as a sliding connection. The sanitary interface can also comprise a latching connection, by means of which the connection between the two connecting elements can be secured against unintentional release.

In this case, the connecting elements can each have a corresponding component which is inserted into the rotary connection. Between the connecting elements, sealing elements, in particular axial sealing elements, such as axial sealing rings, can be arranged and/or formed.

In one embodiment of the sanitary interface, it is provided that the connection of the first connection element to the second connection element can be carried out in at least two different orientations of the two connection elements relative to one another. In this way, the connection between the two connecting elements can be performed in at least two defined angular positions relative to each other. In particular, if one of the two connecting elements is or is formed or arranged on the outlet of the sanitary fitting, the outlet can therefore be arranged in the sanitary fitting in at least two different installation positions and can be connected to the second connecting element of the sanitary fitting in both installation positions.

In one embodiment of the sanitary interface, it is provided that the first connecting element has a guide mechanism. The guide means can define the direction of connection of the two connecting elements, as already mentioned above. The guide means can clearly predetermine the connection direction to be followed in order to establish a connection between the two connection elements as intended. This facilitates as simple an installation of the sanitary fitting as possible even in narrow installation conditions.

By means of the aforementioned guide means, an orientation of the first connecting element relative to the second connecting element can also be achieved when connecting the first connecting element to the second connecting element. The guide means of the first connecting element can thus unambiguously determine the relative position of the second connecting element with respect to the first connecting element. The guide means can thus predetermine at least one well-defined relative position of the two connecting elements with respect to one another, in which a connection between the two connecting elements is established as intended.

In one embodiment of the sanitary interface, it is provided that the first connection element and/or the second connection element have a sealing surface surrounding the liquid line. The sealing surface may be an annular sealing surface. When the circumferential sealing surface is formed on the first connecting element, it can be axially loaded by the second connecting element in the use position. When the circumferential sealing surface is formed on the second connecting element, it can be axially loaded by the first connecting element in the use position.

In one embodiment of the sanitary fitting, the two connecting elements can be connected to one another in a movement transverse to the flow direction of the liquid via a liquid line formed by the connecting elements. In this case, for example, the axial seal already mentioned above can be formed and/or closed between the first connecting element and the second connecting element.

To solve this object, a sanitary fitting having a sanitary interface according to the invention is also proposed.

In order to solve this object, a modular kit for producing a sanitary connection, in particular a sanitary connection according to the invention, is finally proposed, which is characterized in that the modular kit has at least two outlet pieces for sanitary fittings with differently angled sealing surfaces and/or at least two hose nipples with different angles and/or at least two hoses with hose ends with different angles.

Finally, to solve this object, the invention also provides the use of a sanitary fitting according to the invention in a water guide of a sanitary fitting. The water guide can be functionally separated from the mechanical fastening of the sanitary functional part, for example the outlet part and/or the jet regulator, which is to be fastened in or on the sanitary fitting. By using the sanitary interface, the sanitary fitting can be constructed freely and independently of the water guide.

Detailed Description

In the following description of the different embodiments of the invention, elements which are functionally identical, even in the case of different designs or shapes, have been given identical reference numerals.

All the figures show at least part of a sanitary interface, indicated as a whole with 1, having a first liquid-conducting connecting element 2 and a second liquid-conducting connecting element 3. The first connecting element 2 and the second connecting element 3 are connected to one another in the position of use and form a liquid line which is sealed off from the outside. The second connecting element 3 is designed or arranged according to an embodiment of the sanitary fitting 1 on the hose end 4 of the hose 9.

The fluid line formed by the two connecting

elements

2 and 3 is sealed at the connection point 5 between the first connecting element 2 and the second connecting element 3 by an axial seal 6. In all the sanitary interfaces 1 shown in the figures, the first connecting element 2 is designed or arranged on the sanitary function 7.

In the two exemplary embodiments of the sanitary fitting 1 shown in fig. 17 to 24, the axial seals 6 are each designed as an unreleasable axial seal 6. In order to form the non-releasable axial seal 6, the first connecting element 2 and the second connecting element 3 are connected to one another in a material-locking manner. In the embodiment of the sanitary interface 1 shown in fig. 17 to 19, the first connecting element 2 and the second connecting element 3 are welded to each other, for example by ultrasonic welding. In the embodiment of the sanitary interface 1 shown in fig. 20 to 24, the two connecting

elements

2 and 3 are connected to each other by laser welding. One of the two connecting

elements

2, 3 can provide an opaque surface, while the other of the two connecting

elements

2, 3 provides a transparent surface.

In other embodiments, the

connection elements

2, 3 are connected by ultrasonic welding.

Fig. 20 to 22 show that laser welding as a method for connecting two connecting

elements

2 and 3 allows just a relatively large degree of freedom in design. In each of the three sanitary interfaces 1 shown in fig. 20 to 22, second connecting element 3 is fastened to first connecting element 2 in a different angular position.

In the exemplary embodiment of the sanitary fitting 1 shown in fig. 1 to 16, the connection points 5 between the first connecting element 2 and the second connecting element 3 are each sealed by a releasable axial seal 6 in the form of an axial sealing ring. In the embodiment of the sanitary fitting 1 shown in fig. 1 to 8, the axial seal 6 is a rounded, in this case circular, axial sealing ring.

In the exemplary embodiment of the sanitary fitting 1 shown in fig. 9 to 11, a circular axial sealing ring is used as the axial seal 6.

The axial seal 6 of the exemplary embodiment of the sanitary fitting 1 shown in fig. 12 to 16 is a sealing ring with a shape which is similar to a rectangle with rounded inner and outer corners and can also be referred to as an extended ellipse.

In the embodiment of the sanitary interface 1 shown in fig. 1 to 8 and 12 to 16, the second connection element 3 has a hose nipple 8. In the embodiment of the sanitary coupling 1 shown in fig. 9 to 11, the first connecting element 2 comprises a hose nipple 8 which receives the second connecting element 3 formed on the hose end 4 of the hose 9.

The sanitary fitting 1 shown in the remaining figures has a second connecting element 3, which is designed as a hose 9. In a sanitary interface 1 comprising a hose nipple 8 to which a hose 9 is connected, the hose nipple 8 and the hose 9 may be constructed of the same material and/or integrally.

In all the embodiments of the sanitary fitting 1 shown in the figures, the first connecting element 2 is designed as a water outlet 10 for a sanitary fitting 11 and thus as a functional part 7. Embodiments of the sanitary fitting are shown, for example, in fig. 8, 15, 16 and 19 and 24. The outlet elements 10 are each intended to receive a jet regulator 17. The jet regulator 17 is also the functional part 7 for the sanitary fitting 11, as is the outlet part 10.

In a further embodiment, which is not shown, the connecting element 2 is integrally formed directly on the jet regulator 17, so that it forms the outlet piece 10.

In another embodiment, also not shown, the water outlet piece 10 does not have a jet regulator 17.

Fig. 17 to 24 show an embodiment of the outlet 10 without the hose nipple 8.

In particular, the outlet piece 10 of the embodiment of the sanitary fitting 1 shown in fig. 1 to 16 can be constructed from a different material than the respective hose 9 and/or the respective hose nipple 8.

In particular, in the embodiment of the sanitary fitting 1 shown in fig. 9 to 16, the connection direction for connecting the first connecting element 2 and the second connecting element 3 is oriented transversely or perpendicularly to the throughflow direction of the liquid through the liquid line of the sanitary fitting 1. In all sanitary connections 1, it is provided that at least one of the two

connection elements

2, 3, i.e. the respective first connection element 2, has at least one fastening element 12, which can be connected to a mating fastening element 13 of the sanitary fitting 11, which mating fastening element is adapted to the fastening element, into which mating fastening element the respective first connection element 2 is inserted.

In the sanitary fitting 1 shown in fig. 1 to 8, the connection between the two connecting

elements

2 and 3 of the sanitary fitting 1 is designed as a plug-in swivel connection. The working of the interposed rotary connection between the two connecting

elements

2 and 3 can be clearly seen by comparing on the one hand fig. 4 and 5 and on the other hand fig. 6 and 7. Fig. 5 and 7 in this case contain enlarged individual component views for illustrating the connection between the two connecting

elements

2 and 3.

The sanitary interface 1 shown in fig. 12 to 16 is configured such that the connection of the first connecting element 2 and the second connecting element 3 is possible in at least two different orientations of the two connecting

elements

2 and 3 relative to one another. The connection of the sanitary interface 1 between the two connecting

elements

2 and 3 shown in fig. 12 to 16 can be referred to as a sliding connection, which furthermore comprises a latching connection 14 with corresponding latching elements and mating latching elements.

In the embodiment of the sanitary fitting 1 shown in fig. 1 to 8, 9 to 11 and 12 to 16, the second connection element 3 has a sealing surface 15 around the liquid line. The sealing surface 15 is of annular design and is axially acted on by the first connecting element 2 of the sanitary fitting 1 in the use position, in particular in order to press the axial seal 6 against the sealing surface 15 of the second connecting element 3. The exemplary embodiment of the sanitary fitting 1 shown in fig. 1 to 8, 9 to 11 and 12 to 16 has a guide mechanism 16, which is arranged or formed on the first connecting element 2. The direction of connection of the two connecting

elements

2 and 3 is defined by the guide means 16. Furthermore, the guide mechanism 16 predetermines the orientation of the first connecting element 2 relative to the second connecting element 3 when connecting the two connecting

elements

2 and 3. The guide mechanism 16 on the connecting element 2 of the sanitary fitting 1 shown in fig. 1 to 8 comprises a plug guide which predefines the plug direction of the two connecting

elements

2 and 3 for establishing a connection between the two connecting

elements

2 and 3.

The guide mechanism 16 of the first connecting element 2 of the sanitary interface 1 shown in fig. 9 to 11 and 12 to 16 can be referred to as a sliding guide, since it defines and predetermines a sliding movement transverse or perpendicular to the throughflow direction of the liquid through the liquid line. Furthermore, the two guide means 16 of the sanitary fitting 1 shown in fig. 9 to 11 and 12 to 16 have at least one end stop which defines and specifies a defined connection position of the two connecting

elements

2 and 3 to one another.

A similar end stop is also predefined in the guide mechanism 16 of the sanitary interface 1 shown in fig. 1 to 8. Furthermore, the guide mechanism 16 of the sanitary fitting 1 shown in fig. 1 to 8 comprises a rotation guide, by means of which the rotational component of the connecting movement is guided when the plug-in rotational connection between the two connecting

elements

2 and 3 is established.

Each sanitary interface 1 is understood to be a design of a modular kit for producing the sanitary interface 1. The modular kit comprises at least two outlet fittings 10 for sanitary fittings 11 with differently angled sealing surfaces 15 and/or at least two hose nipples 8 with different angles and/or at least two hoses 9 with hose ends 4 with different angles.

In at least some of the sanitary interfaces shown in the figures, the first connecting element 2 and the second connecting element 3 are connected to each other by a movement transverse to the throughflow direction of the liquid through the liquid line formed by the connecting

elements

2 and 3. This results in an axial seal 6 being formed or closed between the first connecting element 2 and the second connecting element 3.

The aforementioned sanitary fitting 1 is therefore used in the water guide of the sanitary fitting 11. The water guide is functionally separated from the mechanical fastening of the sanitary function part 7 (for example the outlet part 10 and the jet regulator 17). In this way, the sanitary fitting 11 can be designed freely to a large extent, independently of the requirements according to the prescribed water guide. Thus, the housing 18 of the sanitary fitting 11 (which itself accommodates the sanitary interface 1) can be made of wood, for example, since the housing 18 itself does not have to be constructed of a water-resistant material since the sanitary interface 1 has its own water-conducting components.

The present invention is directed to improvements in the field of sanitary interface technology. For this purpose, in particular, a sanitary fitting 1 is proposed, the two connecting

elements

2 and 3 of which form, in the connected state, a fluid line which is sealed at a connecting point 5 between the first connecting element 2 and the second connecting element 3 by means of an axial seal 6.
