Description

The invention relates to a sanitary outlet device with a housing which forms a jet shaper receptacle into which an adapter is removably inserted, which defines a flow path, the adapter in the jet shaper receptacle between a fixing position in which the adapter is locked to the housing and a Forms flow resistance in the flow path, and a releasing position in which the adapter is removable from a jet shaper receptacle, is rotatably arranged.

The invention further relates to a sanitary fitting with a sanitary outlet device of the type mentioned at the beginning.

It is known to create sanitary outlet devices with which a jet that emerges from a fitting at a fitting outlet is shaped and / or the flow rate is regulated. For example, it is known to generate aerated or non-aerated water jets which consist of one jet or can be composed of several individual, separate partial jets.

For this purpose, adapters are used which produce the desired spray pattern. In the medical environment in particular, it is necessary to regularly exchange such adapters in order, for example, to prevent hygienically questionable contamination.

From the DE 10 2007 025 290 A1 a sanitary outlet device of the type mentioned is previously known, which can be mounted on the water outlet of a sanitary outlet fitting, in order to shape the water exiting there into a homogeneous and non-spraying water jet. The known outlet device has a sleeve-shaped housing which has an internal thread on its inner circumference of the housing on the inflow side, with which internal thread the housing can be screwed onto an external thread on the water outlet of the outlet fitting. The housing of the known outlet device forms a beam shaper receptacle into which an adapter is removably inserted. The adapter, which is flushed by the exiting water and thus defines a flow path, can be moved in the jet shaper receptacle of the housing between a fixing position in which the adapter is locked to the housing and forms a flow resistance in the flow path, and a releasing position in which the adapter can be removed from the beam former holder. For this purpose, the adapter has spring arms with external locking projections which, in the fixing position, engage in a circumferential locking groove on the inner circumference of the sleeve of the housing. In order to prevent the spring arms from deflecting in the fixing position and thus preventing the locking projections from moving out of the locking groove, a locking element is provided which is axially displaceably guided in the adapter. While the locking element prevents unintentional deflection of the spring arms in the fixing position, the locking element, when it has been moved in the axial direction into the releasing position, releases an annular gap which enables the spring arms to spring in and thus the locking projections to disengage from the locking groove. If the locking projections on the spring arms are locked in the locking groove in the fixing position, the adapter can be rotated as required in the water outlet.

Due to the different com components, the previously known discharge device is comparatively complex to manufacture and design. Since the locking element is movably guided in the annular gap between the adapter and its spring arms, the locking element can only be operated at the downstream end of the adapter, which makes handling of the known outlet device considerably more difficult.

The invention is therefore based on the object of creating a sanitary outlet device of the type mentioned at the outset, in which the adapter can be replaced easily and in a particularly simple manner without tools.

According to the invention, the features of claim 1 are provided to achieve the stated object in a sanitary outlet device. The advantage here is that the adapter can be firmly attached to the beam shaper receptacle in the fixing position, so that the flow obstacle or flow resistance that the adapter forms in the flow path during operation does not result in the adapter automatically moving away from its fixing position . Since the adapter is locked in the fixing position on an outside of the housing with the housing, locking means and counter-locking means are ver in the interior and in particular in the beam shaper receptacle indispensable. The housing can thus be provided with a smooth inner contour that forms as few contamination zones as possible. The adapter can be transferred into a releasing position by a simple rotation, in which the adapter can be removed. No further operating steps are therefore required to remove the adapter. For this purpose, the housing of the outlet device according to the invention has a non-round contour on an outside at least in one section. The advantage here is that the locking connection can be released by turning the adapter. In this case, when the adapter is rotated, the non-round contour displaces a locking means on the adapter from engagement with a counter-locking means on the housing. Thus, a simple way is described to release the already mentioned latching by rotating the adapter. This can be done, for example, by a rotation of less than 270 ° or less than 180 °, for example less than 100 °, in particular approximately or exactly 90 °. With a comparatively high holding force of the latching, a low release force is therefore required in order to transfer the adapter into the releasing position and to pull it off from the housing there. There is no need for a tool.

In an advantageous embodiment, it can be provided that the adapter can be inserted into the jet shaper receptacle in a direction of insertion into the jet shaper receptacle that is oriented against a flow direction of the flow path. The adapter can thus be easily inserted into the beam former holder from below. The existing opening as a water outlet can thus be used to insert the adapter. In contrast, the adapter can be moved by a flow in the flow path also push them out of the beam former holder. Additional measures for removing the adapter in its releasing position from the beam shaper receptacle can thus be dispensed with. Rather, the adapter can be removed in a simple manner by opening the fitting to which it is attached, as soon as it has been transferred into the releasing position.

An advantage over those known in the prior art DE 20 2009 012 719 U1 is that the jet regulator engages with a sealing lip in the through opening of the attachment and seals there. In this way, bag-like spaces can be avoided up to the sealing limit, in which stagnant water, which is hygienically questionable, could collect. Another advantage of the invention over the in DE 20 2009 012 719 U1 The proposed coarse thread is that the adapter can be used in any orientation and can then be transferred into a locking position by a simple rotation.

In an advantageous embodiment it can be provided that the adapter engages around the housing. The adapter can thus be grasped on all sides outside the housing. It is also advantageous that the locking means and counter-locking means, with which the adapter can be locked on the housing, can be formed on the outside of the housing and thus outside the flow path. Potential contamination points in the flow path can thus be avoided.

In an advantageous embodiment, it can be provided that the adapter is arranged in the jet shaper receptacle so that it can rotate about an axis of rotation aligned along the flow path and that the fixing position and the releasing position are arranged at the same height with respect to the insertion direction of the adapter. Thus the adapter is from the fixed position can be transferred into the releasing position with the aid of an actuating movement, which is typically easily accessible in the case of valve spouts because it can be carried out obliquely from above on a valve spout that is open at the bottom.

Since in this embodiment the fixing position and the releasing position are arranged at the same level with respect to an insertion direction of the adapter, for example the already mentioned insertion direction or the insertion direction for the already mentioned insertion of the adapter, threads or the like are on the adapter or the Housing dispensable. In particular, complex machining of a housing made of a metallic material can thus be dispensed with. The transfer between the positions can thus be carried out by a movement that takes place in an axial plane.

In general, it can be provided that the adapter consists of plastic or a plastic combination and / or the housing consists of a metallic material. In particular, a housing made of metallic material offers the advantage that it can be cleaned easily and thoroughly. An adapter made of plastic offers the advantage that complex shapes can also be implemented with comparatively little effort and / or that an adapter can be produced with comparatively low material costs. This makes it easier to use the adapter of a sanitary outlet device according to the invention as a disposable product. Designing all components from a uniform material facilitates the recovery of the material.

In an advantageous embodiment, it can be provided that the non-round contour has a flattening that is limited to a circumferential section and / or a contour / run-on bevel running in a circumferential direction. Thus, for example, a locking means, which is connected to the housing in a locking manner outside the circumferential section, can be removed from the housing in the area of the flattened area.

If the non-circular contour has a contour run-on slope running in a circumferential direction, a latching means on the contour run-on slope can be displaced or displaceable from engagement with a counter-latching means which is formed according to the invention on the housing.

In one embodiment of the invention it can be provided that the adapter is non-circular on the outside, in particular with at least one protruding handling projection. The advantage here is that the adapter can easily be gripped for performing the rotary movement already described. It is particularly favorable if the adapter is equipped with at least one protruding handling projection, preferably with two diametrically opposite, each protruding handling projections. Thus, a simple means is provided to carry out the desired rotary movement in the releasing position. As a result of the formation of handling projections or of a handling projection, the orientation of, for example, a latching means in the interior of the adapter can also be easily displayed or simply felt to the user. This makes it easier to correctly attach the adapter to the beam shaper holder, so that it can be turned directly into to get to the fixed position.

In one embodiment of the invention, it can be provided that the locking means is a locking projection and the counter-locking means is a locking receptacle and that the counter-locking means is designed as a groove section preferably limited to a circumferential section. The advantage here is that a locking projection and a locking receptacle represent known connecting means in order to establish a locking connection.

According to the invention, the locking means is formed on the adapter and the counter-locking means is formed on the housing.

In this embodiment of the invention it is provided that the counter-locking means is designed as a groove section. Thus, locking projections or locking lugs can simply lock with the counter locking means. It is particularly favorable if the groove section is limited to a circumferential section. It can thus be achieved that the latching can be canceled by, for example, moving the latching means out of this peripheral section, in particular by rotating the adapter relative to the housing.

In one embodiment of the invention it can be provided that the locking means is formed on an inner surface of the adapter. The advantage here is that the locking means is covered in the operating position on the valve. It is particularly favorable if the latching means is formed on an inner surface of the adapter, which preferably runs circumferentially without interruption, if the inner surface has a Defined inner diameter and / or an inner circumference, which is matched to an outer diameter and / or an outer circumference of the housing, and if an attachment aid is formed upstream of the counter-locking means in the insertion direction. The adapter thus fully encompasses the housing in the area of the latching means and thus provides sufficient resistance against too easy displacement of the latching means radially outwards. This improves the strength of the latching connection between the adapter and the housing, so that it can be ensured that the adapter is not unintentionally pushed out of the beam former receptacle or cannot be pushed out.

It can be provided here that the inner surface defines an inner diameter which is matched to an outer diameter of the housing, that is to say, for example, matches this up to a predetermined fit. Thus, for example, a play-free arrangement of the adapter on the housing in the fixed position can be achieved, which results in a particularly firm latching. As an alternative or in addition, it can be provided that the inner surface defines an inner circumference which is matched to an outer circumference of the housing, that is to say, for example, corresponds to this up to a predetermined fit. This represents an alternative possibility of achieving a virtually or completely play-free abutment of the adapter on the housing, and can be combined with the preceding embodiment in order to achieve a particularly firm hold.

In this embodiment of the invention it is provided that an attachment aid is formed upstream of the counter-locking means in the insertion direction. Thus are a simple Detection of a correct mounting orientation and / or a simple alignment of the adapter for insertion achievable. In this case, the attachment aid can be designed, for example, as an indentation if the locking means forms an elevation, for example a locking projection. A collapse of the elevation into the indentation, that is, a correct assembly position, can thus be easily felt by turning the adapter. Conversely, the attachment aid can also be designed as an elevation if this fits the inner contour of the adapter and in particular the latching means, for example a latching groove.

In one embodiment of the invention it can be provided that the latching projection has a latching projection run-on bevel that is oriented in the direction of insertion and preferably attaches to the inner surface. This can make it easier for the adapter to latch onto the housing.

In one embodiment of the invention it can be provided that the counter-locking means is formed on the outside of the housing and has a counter-locking means run-up bevel. The counter-locking means can thus be formed outside of the flow path, so that unnecessary points of contamination can be avoided. In particular, it can be provided here that the counter-locking means has a counter-locking means run-up bevel. This makes it easier for the latching means and the counter-latching means to latch when the adapter is connected to the housing.

In one embodiment of the invention it can be provided that the jet shaper receptacle is designed to widen in the direction of flow. This enables sealing insertion of the adapter into the beam shaper receptacle even with manufacturing tolerances of the adapter.

In one embodiment of the invention, it can be provided that the adapter is deformed at its end on the inflow side in the inserted state by the beam shaper receptacle. Thus, a simple possibility is described to let the adapter rest close to the beam shaper receptacle. It is particularly advantageous if the jet shaper receptacle is designed to widen in the direction of flow for this purpose. Thus, a desired deformation can be easily achieved when inserting the adapter into the beam shaper receptacle, for example by manufacturing the adapter with an oversize with respect to the position and deformed dimension it assumed before the beam shaper receptacle.

In one embodiment of the invention, it can be provided that the adapter has an elastic sealing lip resting against the jet shaper receptacle at its end on the inflow side and / or has a sealing ring resting axially on a jet shaper and resting against the jet shaper receptacle. If the adapter has a sealing lip resting on the beam shaper receptacle, an intermediate space between the adapter and the beam shaper receptacle can easily be sealed. It is particularly advantageous if the sealing lip is formed on an end of the adapter on the inflow side. The advantage here is that no gap areas between the adapter and the jet former receptacle are accessible from the flow path. Alternatively or additionally it can be provided that the sealing lip is elastic. This enables a simple deformation of the adapter, for example in the case of the already described expanding design of the beam shaper receptacle. For example, the elastic sealing lip can be rubber-free in order to prevent colonization of the Avoid or at least reduce sealing lip with bacteria.

Alternatively or additionally, it can be provided that the adapter preferably has a sealing ring resting on the jet shaper receptacle at its end on the inflow side. A particularly tight seal can thus be achieved with simple means. The sealing ring is preferably held axially on the jet shaper on one side or even on both sides, in order to hold the sealing ring on the jet shaper when it is inserted into the jet shaper receptacle or even when it is inserted and pulled out. Thus, water contact with the sealing ring, which can be made of rubber, can be tolerated, since the sealing ring is always replaced with the jet shaper. This can be ensured, for example, by mounting on both sides of the beam shaper. Here, the sealing ring, preferably over a shoulder or at least one radially protruding projection, on one side (for insertion into or withdrawal from the jet shaper receptacle with the jet shaper) or, preferably over two shoulders directed against one another and the sealing ring between them, or at least two radially protruding, axially spaced apart and / or the sealing ring between them, projections, be axially held on both sides (for insertion into and removal from the beam former receptacle with the beam former). For example, the sealing ring can also be made of rubber when it comes into contact with water during use, since it is frequently replaced.

It is particularly favorable if the sealing ring is preceded by a sealing lip formed on the jet shaper, for example as already described. Thus are the advantages a sealing lip, namely in particular the hygienic safety, can be combined with the advantages of a sealing ring, namely in particular the increased tightness.

In one embodiment of the invention it can be provided that the adapter is made of plastic. This enables a comparatively free design of the adapter to achieve a desired spray pattern.

It can be provided that the adapter has a jet shaper, in particular a flow regulator or jet aerator. This makes it possible to set a desired upper limit for a flow rate with the adapter. Alternatively or additionally, the adapter can be designed as a ventilated adapter. A ventilated adapter enables air to be mixed in to create a soft jet of water. The adapter can additionally or alternatively be equipped with further functional units, for example a throttle, depending on the requirements.

It is particularly favorable if the latching means have at least two latching projections, preferably engaging on opposite sides of the housing, and the counter-latching means have at least two latching recesses, preferably arranged on opposite sides. If the locking means have at least two locking projections engaging on the housing, a secure hold in the fixed position is made possible with active locking. It can be provided here that the locking means are formed on two opposite sides of the housing, this embodiment not being covered by the wording of claim 1. According to claim 1, the locking means are arranged on the adapter and the counter-locking means on the housing. A two-sided hold on the housing can thus be achieved, which - in the fixed position - enables the adapter to be held particularly securely on the housing. It is like that, for example a hold of the adapter can be achieved even at high water pressures.

At least four latching means and / or suitable counter-latching means can thus also be formed. Correspondingly, at least four handling projections can be formed, which are best evenly spaced from one another.

In one embodiment of the invention it can be provided that the counter-locking means have at least two locking recesses. This enables locking at two points that are spaced apart from one another. The counter-locking means are preferably arranged on opposite sides of the housing. It is particularly advantageous here if the latching means likewise have corresponding latching projections engaging two mutually opposite sides on the housing.

There are also three or more than three latching means - preferably evenly distributed along a circumference - and corresponding counter-latching means can be formed.

In general, it can be said that it is advantageous to distribute many different locking means in the circumferential direction. In this way, the sealing lip or the sealing ring can be held as uniformly as possible in the interior of the jet former receptacle. To reinforce the adapter, the already mentioned handling projections and / or other material reinforcements can be provided on the outside, for example to increase a restoring force of the locking means.

In one embodiment of the invention it can be provided that the inner surface between two detent means adjacent in the circumferential direction describes a section of a body of revolution. The advantage here is that a rotary movement can be carried out easily. Alternatively or additionally, it can be provided that the outer surface of the housing describes a section of a body of rotation between two counter-locking means that are adjacent in the circumferential direction. Here, too, simple guidance of a rotary movement is made possible. It is particularly favorable if the inner surface and the outer surface in the sections mentioned describe the shape of a body of revolution. Thus, the inner surface and the outer surface can slide on one another to guide the rotary movement of the adapter.

In one embodiment of the invention, it can be provided that the housing has a fitting receptacle with a thread at an inflow end of the flow path, which can be screwed to a mating thread of a fitting outlet. The advantage here is that the housing can be easily attached to valve outlets that have a thread. The housing is therefore also exchangeable.

In one embodiment of the invention it can be provided that a jet-changing inner part is detachably inserted as an insert cartridge in the adapter. The adapter can thus be equipped with a functionality with which a desired jet property, for example in the degree of air admixture, a cross-sectional shape, a flow velocity, a flow profile and / or a flow rate, can be set. A desired functionality can thus be easily changed or renewed by exchanging the adapter. For example, in a structurally simple case, the adapter can be used with a control star be trained. It is particularly favorable if the inner part is connected in one piece to the adapter.

In one embodiment of the invention it can be provided that a beam-changing inner part is arranged on the adapter in a detachable manner. The advantage here is that the adapter can be reusable when the inner part is replaced. It also has to be a variety of different

Internal parts can only be provided with a common adapter. This simplifies storage. The jet-variable inner part can be designed, for example, as an insert cartridge and inserted into the adapter.

In one embodiment of the invention, it can be provided that the locking means and / or the counter-locking means define a release angle of more than 90 °. The advantage here is that a large holding force can be generated. The release angle can be, for example, an angle that is enclosed by the insertion direction and an inclined surface absorbing the holding force, in particular where the angle lies in the material and / or an angle of more than 90 ° indicates an inclination of the latching means on the counter-latching means (or vice versa) .

The invention also provides a sanitary fitting with a sanitary outlet device according to one of the claims directed to a sanitary outlet device, wherein the sanitary outlet device is screwed to a fitting outlet of the sanitary fitting. The sanitary outlet device can thus be easily retrofitted. Alternatively, it can be provided that the housing of the sanitary outlet device is formed in one piece on a fitting outlet of the sanitary fitting. The housing is thus arranged on the sanitary fitting so that it cannot be replaced or removed without being destroyed.

The invention will now be described in more detail with reference to exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments result from the combination of the features of individual or several protection claims with one another.

In the following, the Figures 1 to 5 described together.

A sanitary outlet device designated as a whole by 1 has a housing 2. A jet shaper receptacle 3 is formed on the inside of the housing 2.

An adapter 4 is inserted into the beam shaper receptacle 3 and can be removed from the beam shaper receptacle 3 in a manner to be described in more detail.

The adapter 4 defines a flow path 5 for water flowing through. For this purpose, the adapter 4 is equipped with a beam-changing inner part 31 which, for example, can form a control star, a jet regulator, a jet limiter and / or a jet shaper. This inner part 31 is inserted as an insert cartridge 32 into a cartridge receptacle 33 up to a stop 34. The insertion takes place here in a flow direction of the flow path 5, so that the insert cartridge 32 is held in its use position by the stop 34.

The adapter 4 is according to a fixing position Figure 2 latched to the housing 2 in a manner to be described in more detail. The adapter 4 is rotated into the position according to FIG Figure 3 can be transferred, in which the adapter 4 can be removed from the housing 2 and thus from the beam shaper receptacle 3. This position according to Figure 3 is thus a releasing position of the adapter 4.

From a synopsis of the arrangements according to Figure 5 , Figure 4 and Figure 3 it can be seen that the adapter 4 can be inserted into the jet shaper receptacle 3 against a flow direction of the flow path 5. As far as the releasing position according to Figure 3 is occupied, the adapter 4, which represents a flow obstacle in the flow path 5, is forced out of the beam former receptacle 3.

In particular from the completely withdrawn illustration according to Figure 1 and Figure 5 it can be seen that the adapter 4 engages around the housing 2 along the entire circumference.

The adapter 4 is rotatably arranged about an axis of rotation 6 which is aligned along the flow path 5. As a result of this rotation, the adapter 4 can be adjusted between the fixing position and the releasing position.

With respect to this axis of rotation 6, the fixing position is shown in FIG Figure 2 and the releasing position according to Figure 3 arranged at the same height. The axis of rotation 6 also specifies an insertion direction 7 of the adapter 4 for insertion into the beam shaper receptacle 3, so that the fixed position and the releasing position are also arranged at the same height in relation to this insertion direction 7. A transfer movement between the positions thus runs in an axial plane.

In the fixing position, the adapter 4 is latched to the housing 2 on an outer side 8 of the housing 2. For this purpose, a non-round contour 10 is formed on the outside 8 at least in one section 9.

In the exemplary embodiment, this contour 10 is formed by a flat 11 which interrupts an otherwise circumferential groove 12.

This means that when the adapter 4 A latching means 13 around the axis of rotation 6, which engages in a latching manner in the groove 12 as a counter-latching means 15 in the form of a latching projection 14, is released in the region of the flat 11. As soon as the locking means 13 is thus positioned over the flat 11, the adapter 4 can be removed from the housing 2. As long as the latching means 13 is latched to the counter-latching means 15, the adapter 4 cannot be removed and the adapter 4 is fixed in the beam shaper receptacle 3.

The adapter 4 itself is not round on the outside and has two handling projections 16 diametrically opposite one another. A user can easily grip the adapter 4 at these handling projections in order to rotate it about the axis of rotation 6 between the fixing position and the releasing position.

In Figure 1 it can also be seen that the groove 12 is limited as a groove section 17 to a circumferential section 18 of the housing 2. This limitation is given on two sides by a flat 11 each.

As a result, the releasing position can be assumed in two positions offset by 180 °, since the latching means 14, which are also limited in the circumferential direction, can be pulled off the housing 2 via the flats 11.

This groove section 17 thus forms a latching receptacle 19 for the latching projection 14.

In Figure 1 it can also be seen that the latching means 14 are formed on an inner surface 20 of the adapter 4. The inner surface 20 is designed to run around without interruption.

This causes a particularly strong resistance to deformation of the locking projections 14 radially outward. The latching thus holds particularly well.

The inner diameter and the inner circumference of this inner surface 20 are matched to the outer diameter and the outer circumference on the outer side 8 of the housing, so that the inner surface 20 rests flat against the outer side 8 in a latched, i.e. fixing, position.

The inner surface 20 is thus supported between the latching projections 14 on the housing 2, as a result of which an increased strength of the latching is achieved.

In order to facilitate locking when the adapter 4 is plugged in, a locking projection stop bevel 21 is formed on the locking projection, which is oriented in the insertion direction 7 and which interacts with a counter-locking means stop bevel on the outside 8 in the area of the counter-locking means 15.

At least one access opening 35 is formed on the outlet side of the adapter 4, through which a pointed tool can be inserted. Thus, for example, supported on the counter-locking means contact bevel serving as guide bevel 36 or - in further exemplary embodiments - on a separate guide bevel, the locking means 13 can be brought out of an engagement position with the counter-locking means 15 without rotating the adapter 4 in order to pull off the adapter 4.

The jet shaper receptacle 3 has an inner cone 23 by means of which it is designed to widen in the direction of flow, that is to say along the flow path 5.

The adapter 4 is dimensioned in such a way that it is deformed by the inner cone 23 when it is inserted into the beam former receptacle 3.

For this purpose, the adapter 4 has a circumferential sealing lip 25 made of an elastic, rubber-free material, for example made of plastic, which is deformed radially inward by the inner cone 23 at its end 24 on the inflow side. The sealing lip 25 thus lies tightly against the beam former receptacle 3.

The upstream end 24 of the adapter 4 and the inner surface 20 of the adapter 4 thus accommodate the housing 2 between them.

The adapter 4 can be made of plastic and have, for example, a known flow regulator 26 or a similar jet shaper, for example a jet aerator, behind an attachment screen 27 in the interior, approximately at the point indicated by the arrow.

The adapter 4 can additionally or alternatively be designed as a ventilated adapter 4 in a manner known per se.

It can also be seen from the figures that the already mentioned inner surface 20 and the outer side 8 on the other side of the latching means 13 or the counter-latching means 15 each describe a section of a body of revolution.

In the embodiment according to Figure 1 to Figure 5 the housing is formed in one piece with a fitting outlet 28 of a sanitary fitting 29, which is only indicated here.

In further exemplary embodiments, the housing 2 can in an have a thread in a known manner, which can be screwed to a mating thread of the fitting outlet 28.

Figure 6 shows another embodiment of the invention of a sanitary outlet device. Components and functional units that are functionally and / or structurally similar or identical to the preceding exemplary embodiments are denoted by the same reference symbols and are not described again separately. The explanations regarding the preceding exemplary embodiments therefore apply Figure 6 corresponding.

The embodiment according to Figure 6 differs from the preceding exemplary embodiments in that the non-circular contour 10 is designed with a contour run-on bevel 30. The contour run-on bevels 30 have the effect that the latching projections 14 of the latching means 13 are displaced radially from the groove sections, which here are formed analogously to the groove sections 17 in the preceding figures. The latching is thus released and the adapter 4, which is shown in FIG Figure 6 is shown in the locked, fixing position, can be removed from the housing 2.

In the exemplary embodiments shown and described, the latching means 13 is formed on the adapter 4, while the counter-latching means 15 is formed on the housing 2. In the case of a device that is not claimed, the latching means 13 is designed as a latching projection 14 on the housing 2, while corresponding groove sections 17 are formed in the inner surface 20 in order to achieve a latching receptacle 19 and thus a counter-latching means 15. Here, too, it can be provided that corresponding contour run-on bevels 30 or other non-round contours 10 are formed in the inner surface 20 in order to create a point in a section 9 in the circumferential direction of the inner surface 20 at which the Latching can be canceled. In this case, this point defines the releasing position, while the other angular positions of the adapter adapter 4 in the beam shaper receptacle 3 form the fixing positions. In further exemplary embodiments, other combinations of latching means and counter-latching means known per se are implemented.

The Figures 7 to 9 show a further embodiment of a sanitary outlet device according to the invention. Components and functional units that are functionally and / or structurally similar or identical to the preceding exemplary embodiments are denoted by the same reference symbols and are not described again separately. The statements on the preceding exemplary embodiments therefore apply to the Figures 7 to 9 corresponding.

The embodiment according to Figures 7 to 9 differs from the previous exemplary embodiments at least in that the position of the circumferential section 18 is rotated by 90 °.

Furthermore, another beam-changing inner part 31 is used to one Fig. 1 Define different beam shape or beam quality. For this purpose, the insert cartridge 32, such as Fig. 9 shows, can be simply removed from the removed adapter 4 and replaced.

The Figures 10 and 11 show a further embodiment of a sanitary outlet device according to the invention. Components and functional units that are functionally and / or structurally similar or identical to the preceding exemplary embodiments are denoted by the same reference symbols and are not described again separately. The remarks on the previous ones Embodiments therefore apply to the Figures 10 and 11 corresponding.

The embodiment according to Figures 10 and 11 differs from the previous exemplary embodiments at least in that the housing 3 is formed separately from a fitting outlet 28. In this exemplary embodiment, a thread 37 on the housing 3 - here and often an external thread - is screwed to the fitting outlet 28 with a matching mating thread 38 - here and often an internal thread. A seal 39 enclosed on all sides by the material of the housing 3 and the fitting outlet 28 in the position of use seals between the housing 3 and the fitting outlet 28.

Both the housing 3 and the fitting outlet 28 are made of metal or some other material that makes bacterial colonization more difficult or prevents it. The seal 39 can be made of rubber, since contact with running water can be practically excluded.

To replace the adapter 4 and / or the jet-shaping inner part 31, the housing 3 can remain on the fitting outlet 28.

The Figures 12 to 14 show a further embodiment according to the invention. Components and functional units that are structurally and / or functionally similar or identical to the preceding exemplary embodiments are again denoted by the same reference symbols and are not described again separately. The remarks on the Figures 1 to 11 therefore apply to the Figures 12 to 14 corresponding.

In contrast to the preceding exemplary embodiments, the adapter 4 has four handling projections 16 uniformly distributed in the circumferential direction on the outside.

The locking means 13 and the counter locking means 15 are designed with undercuts, so that a release angle of more than 90 ° results.

The locking means 13 and the counter locking means 15 have for this purpose matching sloping surfaces 43 which define a release angle of the locking connection of more than 90 °. Each of the inclined surfaces 43 is thus positioned in the insertion direction 7 against the corresponding inclined surface 43 in such a way that a lateral deflection of the locking means 13 is mechanically prevented when the housing 4 is pulled (and thus when there is pressure due to the water pressure). The release angle thus causes the latching means 13 to interlock with the counter-latching means 15.

An axially oriented slot 44 in the housing 4 is used to provide the necessary freedom of movement for the locking means 13 so that they can be pushed over the counter locking means 15.

In this exemplary embodiment, the insert cartridge 32 is composed as a jet shaper 26 from a dismantling part 45 and an outlet part 47. The sealing lip 25 protrudes here from a base body of the outlet part 47 against the direction of flow. The outlet part 47 can be formed in one piece with the adapter 4 or inserted into it.

The Figures 15 to 21 show a further embodiment according to the invention. Constructive and / or functional to the Components and functional units that are similar or identical to previous exemplary embodiments are again designated by the same reference symbols and are not described again separately. The remarks on the Figures 1 to 14 therefore apply to the Figures 15 to 21 corresponding.

The embodiment according to Figures 15 to 21 differs from the preceding exemplary embodiments at least in that instead of the sealing lip 17, a sealing ring 40, for example an O-ring made of rubber, is provided. Due to its hidden position, the O-ring is not flushed through, although it comes into contact with water.

The jet shaper 26 is again composed of a dismantling part 45 and an outlet part 47. The outlet part 47 can be connected in one piece to the adapter 4, or the outlet part 47 is held by the adapter 4.

On the outlet part 47 and the dismantling part 45, a circumferential shoulder 46 is formed, which receive the sealing ring 40 between them and hold it axially on both sides. The sealing ring 40 with the adapter 4 can thus be inserted and removed again. In further exemplary embodiments, instead of the shoulders 46, radially protruding projections are formed which hold the sealing ring 40 axially in sections.

In the Figures 19 to 21 it can be seen that the fourfold arrangement of the handling projections 16 has a correspondence in the arrangement of the counter-locking means 15 (and correspondingly the locking means 13).

In further exemplary embodiments, a smaller or larger number of handling projections 16, for example three or five or more than five.

Attachment aids 41, which here have the shape of indentations 42, are positioned upstream of the counter-locking means 15 in the insertion direction 7. The latching means 13 are dimensioned in such a way that they are slightly bent open by the cylindrical section of the housing 2. A user can thus easily sense when the locking means 13 come into the circumferential area of the indentations 42 when the adapter 4 is rotated. This thus represents an attachment aid 41, since the latching means 13 are now aligned with respect to the counter-latching means 15 (which may already be covered in this position by the adapter 4) and can easily be attached to them.

In the case of the sanitary outlet device 1, it is therefore generally proposed to form a beam shaper receptacle 3 on a housing 2, in which an adapter 4 is removably inserted and rotatably arranged about its axis of rotation 6, the adapter 4 between a fixing position in which the adapter 4 counter removal is secured, and a releasing position in which the adapter 4 is removable can be rotated.
