Description

[0001] The invention relates to an outlet element for a sanitary fitting with a base element for connection to an outlet having two outlet openings, with a valve device cooperating with the base element and with an actuating element by which the valve device is adjustable and rotatable relative to the base element in order to switch between at least two separate water flows, wherein the valve device for switching interacts with the two outlet openings.

[0002] Such a spout element is known from publication EP 2 573 283 B1. The spout element known from this publication has a base element with at least one through-opening, which is intended for connection to the spout of a sanitary fitting. The spout element further comprises a device that interacts with the base element, a sleeve for fixing the device to the spout, and an actuating element for the device projecting from the sleeve, wherein the device is rotatable relative to the base element.The previously known outlet element is characterized by the fact that the sleeve is provided for holding the base element in the outlet in a non-rotatable manner, the device is a valve device cooperating with the base element for switching between at least two separate water flows, and the actuating element serves to actuate the valve device in such a way that one of the two separate water flows is switched on and remains so until the user switches back to the other water flow.

[0003] The sleeve of the outlet element thus serves not only to at least partially accommodate the actuating element for the device, but also to fix the basic element non-rotatably to the outlet of the sanitary fitting to which the outlet element is to be fitted.

[0004] Further discontinuation elements are known from US 4 221 337 A, US 2014 / 0300010 A1, WO 2021 / 144749 A1, DE 20 2015 103 996 U1, DE 10 2015 002 740 A1, EP 1 443 151 A1, DE 30 06 660 C2 and DE 10 2012 206 181 A1.

[0005] The object of the invention is to provide a discharge element of the type mentioned above which has a simpler design compared to the previously known discharge element.

[0006] To solve the problem, a discharge element with the features of the independent claim directed to such a discharge element is proposed. In particular, to solve the problem, it is proposed that the discharge element has a threaded fitting with an external thread, wherein the threaded fitting is integrally formed on the base element and is designed to captively hold the base element on the discharge.

[0007] In comparison to the outlet element known from publication EP 2 573 283 B1, the outlet element according to the invention can thus be attached to the outlet of a sanitary fitting without a separate sleeve. A separate mounting sleeve, as provided for in the outlet element of publication EP 2 573 283 B1, is therefore unnecessary. This simplifies the design of the outlet element according to the invention and facilitates its simplest possible manufacture and installation. While the outlet element known from the prior art is attached to the sanitary fitting by means of its sleeve, this is achieved in the outlet element according to the invention via the external thread of the threaded stub, which is integrally formed on the base element.

[0008] The threaded fitting and the base element can form a materially homogeneous and / or monolithic unit.

[0009] In one embodiment of the outlet element, the actuating element can be arranged downstream of the threaded fitting. The threaded fitting is preferably arranged on the upstream side of the base element.

[0010] Furthermore, the base element can have an extension on its downstream side, via which the valve assembly can be connected to or is connected to the base element. The extension allows the base element and the valve assembly to be connected to form a single unit. In this context, it can be advantageous if the valve assembly has a corresponding socket on its upstream side for the extension of the base element. The downstream side can be oriented away from the threaded connection of the outlet element.

[0011] It should be mentioned here that the reverse arrangement of extension and socket is also conceivable. In one embodiment of the outlet element, the valve assembly can have an extension on its inlet side for connection to the base element. Correspondingly, the base element can then have a socket for the extension of the valve assembly.

[0012] The aforementioned extensions can be ring-shaped. Furthermore, it is possible that the extension of the base element is integrally formed with the base element. Likewise, it is possible that the valve assembly has an extension that is ring-shaped and / or integrally formed with the valve assembly. The element that does not have an extension, i.e., either the valve assembly or the base element, can then be fitted onto the extension for the purpose of connecting the valve assembly to the base element. In this case, the valve assembly can overlap the extension and / or surround it externally.

[0013] Preferably, the valve assembly can be rotated relative to the base element using the actuating element of the outlet element in order to switch the valve assembly and the base element relative to each other between the at least two switching positions of the at least two separate water channels.

[0014] The valve assembly and / or at least a part of the base element, in particular an extension of the base element, such as the one mentioned above, can be arranged at least partially within a receiving space defined by the actuating element. The actuating element can be designed as an actuating sleeve that receives at least a part of the base element and / or the valve assembly. In one embodiment of the actuating element, it has an actuating wing that can project, for example, radially outwards from a base body of the actuating element to be easily accessible to a user of the outlet element.

[0015] In one embodiment of the outlet element, the actuating element is axially fixed to the valve assembly.

[0016] The actuating element can be configured to actuate the valve device in such a way that one of the at least two separate water lines is switched on and remains switched on until the user switches back to the other water line.

[0017] In one embodiment of the outlet element, at least one notch and at least one corresponding projection are formed between the base element and the valve assembly (3). In the engaged position, these notches and projections can define at least one switching position of the valve assembly relative to the base element. This can improve the operation of the outlet element and its switching accuracy. Preferably, at least one notch is formed on the base element, for example, on its extension, and at least one projection is formed on the valve assembly.

[0018] The invention is described in more detail below with reference to exemplary embodiments, but is not limited to the embodiments shown. Further exemplary embodiments result from combining the features of one or more claims with each other and / or in combination of one or more features of the exemplary embodiments.

[0020] All figures show at least parts of a spout element designated as a whole by 1. The spout elements 1 are suitable for use in or on a sanitary fitting. Each spout element 1 has a base element 2, which is designed to connect to a spout of the sanitary fitting. Furthermore, each spout element 1 includes a valve assembly 3 that interacts with the base element 2 and is adjustable relative to the base element 2 between at least two switching positions for switching between at least two separate water flows 4 and 5; in the specific embodiments of the spout elements 1, it is rotatable.

[0021] Each basic element 2 has at least one outflow-side outlet opening 6. In the specific embodiments of the outlet element 1 shown according to the invention, there are two outlet openings 6. According to the invention, each water guide 4 and 5 is assigned two inflow-side inlet openings 7 and 8 of the valve assembly 3.

[0022] In all the outlet elements 1 shown, it is provided according to the invention that the respective base element 2 has a sealing element 9 with which, in each of the at least two switching positions, a transition between the two downstream outlet openings 6 of the base element 2 and the two upstream inlet openings 7 or 8 of the respective switched water guide 4 or 5 can be sealed.

[0023] The figures show that the respective base element 2 has a sealing receptacle 10 in which the sealing element 9 is arranged. For example, the Fig. 22 and Fig. 23 makes it clear that the sealing receptacle 10 and the sealing element 9 are arranged and designed such that in each of the at least two switching positions, right-angled projections from two of the inlet openings 7 and 8 onto the base element 2 lie within an outer edge of the sealing receptacle 10 and also of the sealing element 9 and also within a cross-section of the base element 2 bounded by the sealing receptacle 10.

[0024] Fig. Figure 22 shows the sealing receptacle 10 with the sealing element 9 in a first switching position of the valve assembly 3. It is clearly visible that the inlet openings 7 of the valve assembly 3 are arranged such that perpendicular projections of the inlet openings 7 onto the base element 2 lie within the outer edge of the sealing receptacle 10 and the outer edge of the sealing element 9 and also within a cross-section of the base element 2 bounded by the sealing receptacle 10.

[0025] The same applies when the valve assembly 3 is in its second switching position with the inlet openings 8 of the second water channel 5 of the valve assembly 3. This can be seen from the Fig. 23 clearly visible.

[0026] According to the Fig. 8-10 The sealing receptacle 10 is formed on a downstream side 11 of the base element 2. The inlet openings 7 of the water guide 4 differ noticeably in their shape and size from the inlet openings 8 of the second water guide 5 of the valve assembly 3.

[0027] The two outlet openings 6 of the base element 2 and at least one of the inlet openings 7 or 8 of one of the at least two water channels 4, 5 of the valve assembly 3 have the same cross-section or at least approximately the same cross-section. According to the Fig. 22 and Fig. 23 these are the inflow-side inlet openings 8 of the second water channel.

[0028] The sealing receptacle 10 is designed as an endless receiving groove and accommodates the sealing element 9. The sealing element 9 can be described as a figure-eight-shaped sealing ring or also as an hourglass-shaped sealing ring.

[0029] The figures illustrate that the base element 2 has a threaded fitting 13 on its inlet side 12, with which it can be screwed, for example, onto the outlet of a sanitary fitting. An external thread 19 is formed on the threaded fitting 13, with which the outlet element 1 can be attached to the outlet of a sanitary fitting via its base element 2. The threaded fitting 13 is integrally formed with the base element 2 and is designed to hold the base element 2 captive on the outlet of a sanitary fitting.

[0030] The base element 2 has a projection 14 on its outflow side 11, via which the valve assembly 3 is connected to the base element 2. The projection 14 is annular and integrally formed on the base element 2, specifically on the outflow side 11. In the operating position, the valve assembly 3 is placed onto the projection 14 of the base element 2. Thus, the valve assembly 3 overlaps the projection 14 and surrounds it on the outside.

[0031] The outlet element 1 has an actuating element 15 with which the valve assembly 3 can be adjusted, i.e., rotated, relative to the base element 2 in order to switch between the two separate water channels 4 and 5. In all illustrated embodiments of the outlet element 1, the actuating element 15 is arranged downstream of the threaded nozzle 13.

[0032] In both outlet elements 1 shown in the figures, the actuating elements 15 are designed such that the valve assembly 3 and the extension 14 of the base element 2 are arranged at least partially within a receiving space 16 defined by the actuating element 15. The actuating elements 15 are thus actuating sleeves that can at least partially receive the valve assembly 3 and the extension 14 of the base element 2.

[0033] The actuating elements 15 of the shown outlet elements 1 are axially fixed to the respective valve assembly 3.

[0034] Each of the actuating elements 15 has at least one actuating wing 17.

[0035] The respective actuating element 15 is designed to actuate the valve assembly 3 connected to it in such a way that one of the at least two separate water lines 4, 5 is switched on and remains switched on until the user switches back to the other water line 4 or 5.

[0036] The Fig. 3 and Fig. Figure 4 shows a beam splitter 18, which, according to the exploded views of the discharge element 1 of the Fig. 3 and Fig. 4 Part of the valve assembly 3 of the outlet element 1 is.

[0037] The Fig. Figures 4 and 8 to 10 show that a total of four notches 20, offset from each other at 90° angles, are formed on the extension 14 of the base element 2. The notches 20 define the switching positions of the actuating element 15 and the valve assembly 3.

[0038] On an inner side of the valve assembly 3, two inwardly directed projections 21 are formed that fit the notches 20. The projections 21 engage in the notches 20 when the valve assembly 3 is moved into the switching positions by the actuating element 15.

[0039] In the sectional view of the Fig. Figure 22 shows how the actuating element 15 is attached to the valve assembly 3. Furthermore, it shows Fig.22, that the base element 2 is snapped into the valve assembly 3. The invention relates to improvements in the field of sanitary engineering. Specifically, an outlet element 1 for a sanitary fitting is proposed, comprising a base element 2 and a valve assembly 3 connected to the base element 2, which can be adjusted between at least two switching positions relative to the base element 2 to switch between at least two separate water flows 4, 5. In order to be able to attach the outlet element 1 to an outlet of a sanitary fitting in the simplest possible way, the outlet element 1 has a threaded fitting 13 with an external thread 19, wherein the threaded fitting 13 is integrally formed on the base element 2.
