Description

Sanitary outlet and sanitary fitting

The invention relates to a sanitary outlet device with a housing, wherein the housing forms a Strahlformeraufnahme into which a jet former is removably inserted, wherein the adapter defines a flow path.

The invention further relates to a sanitary fitting with a sanitary outlet device.

It is known to provide sanitary outlet devices with which a jet emerging from a fitting at a tap outlet is formed and / or regulated in the flow rate. For example, it is known to produce aerated or non-aerated water jets, which may consist of a beam or may be composed of a plurality of individual, separate sub-beams.

For this purpose, adapters are used, which give the desired beam image. Especially in the medical field, it is erforder lent to replace such adapter regularly to example, to prevent a hygienic concern pollution.

For this purpose, it has hitherto been customary to form on the adapters approaches for a tool, with which the respective adapter can be replaced.

The invention is therefore an object of the invention to provide a sanitary outlet device in which the adapter can be replaced without tools.

CONFIRMED U NGSKOPI E According to the invention, the features of claim 1 are provided to solve the above problem in a sanitary outlet. In particular, according to the invention is thus proposed to solve the above problem in a sanitary outlet device of the type described above, that the adapter in the Stahlformeraufnahme between a fixed position in which the adapter is latched to the housing and forms a flow resistance in the flow path, and a releasing position in which the adapter is removable from the Strahlformeraufnahme, is rotatably arranged. The advantage here is that the adapter in the fixing position fixed to the Strahlformeraufnahme so that the flow obstacle or flow resistance that forms or the adapter in operation in the flow path does not cause the adapter automatically moves away from its fixing position , On the other hand, the adapter is convertible by a simple rotation in a releasing position in which the adapter can be removed. 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 equal to 90 °.

In an advantageous embodiment, it may be provided that the adapter mungswegs is used against a flow direction of Strö. Thus, the adapter is easy from un th in the Strahlformeraufnahme used. The already existing IN ANY opening as a water outlet is thus available for insertion de adapter.

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

In an advantageous embodiment, in particular as an alternative or in addition to the previously described embodiment, it can be provided that the adapter can be pushed out of the beam former receptacle by a flow in the flow path. Thus, additional measures for removing the adapter in its releasing position from the Strahlformeraufnahme are dispensable. Rather, the adapter can be easily removed by opening the fitting to which it is attached, as soon as it is transferred to the releasing position.

In an advantageous embodiment it can be provided that the adapter engages around the housing. Thus, the adapter is tangible on all sides outside the housing. Another advantage is that the locking means and counter-locking means with which the adapter can be latched to the housing, outside of the housing and thus outside of the flow path can be formed. Thus, potential contaminants in the flow path can be avoided.

In an advantageous embodiment it can be provided that the adapter is rotatably arranged in the beam former receptacle about an axis of rotation aligned along the flow path. Thus, the adapter can be transferred from the fixed position to the releasing position by means of an actuating movement, which is typically easily accessible at valve outlets, because they are inclined from above at a downwardly open Faucet outlet is executable.

In one embodiment of the invention can be provided that the fixing position and the releasing position at the same height with respect to a plug-in direction of the adapter, for example, the already mentioned plug-in direction or the insertion direction to the already mentioned insertion of the adapter are arranged. Thus, threads or the like on the adapter or the housing can be dispensed with. In particular, a costly machining of a housing made of a metallic material is thus dispensable. The transfer between the positions is thus carried out by a movement that takes place in an axial plane.

In general, it may be provided that the adapter made of plastic or a plastic combination and / or the housing consists of a metallic material / exist. In particular, a housing made of metallic material has the advantage that it is easy and thoroughly cleanable. An adapter made of plastic offers the advantage that even complex shapes can be realized with comparatively little effort and / or that an adapter can be produced with comparatively low material costs. This facilitates use of the adapter of a sanitary outlet device according to the invention as a disposable product. An embodiment of all components made of a uniform material facilitates the recovery of the material.

In one embodiment of the invention can be provided that the adapter is locked in the fixing position on an outer side of the housing with the housing. Thus, locking means and counter-locking means in the interior and in particular in the Strahlformeraufnahme be dispensed with. In particular, the housing is thus providable with a smooth inner contour, which forms as few pollution zones.

In an advantageous embodiment it can be provided that the latching can be released by a rotation of the adapter in the releasing position. The advantage here is that no further operation steps to remove the adapter are required.

In one embodiment of the invention can be provided that the housing has an out-of-round contour on an outer side at least in one section. The advantage here is that, for example, a resolution of a locking connection by turning the adapter is effected. In particular, it can be provided in this case that the non-circular contour during a rotation of the adapter displaces a latching means from engagement with a counter-latching means. Thus, a simple way is described to solve the aforementioned locking by rotation of the adapter. It is thus at a comparatively high holding force of the latching a low release force required to transfer the adapter in the releasing position and deduct there from the housing. Tool is dispensable.

In an advantageous embodiment, it may be provided that the non-circular contour has a limited to a peripheral portion flattening. Thus, for example, a locking means, which is connected outside the peripheral portion latching with the housing, be removable in the region of the flattening of the housing.

Alternatively or additionally, it may be provided that the non-circular contour has a contour run-on slope running in a circumferential direction. A latching means can thus at the contour Starting bevel from engagement with a counter-locking means, which may be formed, for example, on the housing, be displaced or be displaced.

In one embodiment of the invention can be provided that the adapter is formed on the outside out of round. The advantage here is that the adapter for exercising the rotational movement already described is easily accessible. It is particularly advantageous if the adapter is equipped with at least one protruding handling projection, preferably with two diametrically opposed, each protruding handling protrusions. Thus, a simple means is provided to translate the desired rotational movement into the releasing position. Due to 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 easily felt by the user. This facilitates proper attachment of the adapter to the beamformer receptacle for direct entry into the fixed position without additional rotation.

In one embodiment of the invention can be provided that the locking means is a latching projection. Alternatively or additionally, it can be provided that the counter-latching means is a latching receptacle. The advantage here is that a locking projection and a locking receptacle represent known connection means to produce a latching connection.

Generally, it can be said that, for example, the locking means on the adapter and the counter-locking means can be formed on the housing. In other embodiments, it may be the other way round. In one embodiment of the invention can be provided that the counter-locking means is formed as a groove portion. Thus, locking projections or detents can easily lock with the counter-locking means. It is particularly favorable if the groove section is limited to a peripheral section. Thus, it can be ^¬ enough that the latching can be canceled by, for example, the latching means is moved out of this peripheral portion, in particular by rotating the adapter relative to the housing.

In one embodiment of the invention 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 hidden in the operating position on the valve. It is particularly favorable when the inner surface of the adapter is designed to run without interruption. Thus, the adapter engages around the housing in the region of the locking means and thus provides a sufficient resistance against too easy displacement of the locking means radially outward. This improves the strength of the locking connection between adapter and housing, so that it can be ensured that the adapter is not inadvertently forced out of the Strahlformeraufnahme or herausdrängbar. It can be provided that the inner surface defines an inner diameter which is tuned to an outer diameter of the housing, so for example, with this matches up to a predetermined fit. Thus, for example, a play-free arrangement of the adapter to the housing in the fixed position can be achieved, resulting in a particularly strong locking. Alternatively or additionally, 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, this matches up to a predetermined fit over ^¬ . This is an alternative way to achieve a nearly or completely play-free concern of the adapter to the housing, and can be combined with the preceding embodiment in order to achieve a particularly firm grip.

In one embodiment of the invention can be provided that the counter-latching means in the insertion upstream of a Aufsteckhilfe is formed. Thus, a simple detection of a correct mounting orientation and / or a simple orientation of the adapter for insertion can be achieved. Here, the Aufsteckhilfe may be formed, for example, as a molding when the locking means is a survey, for example, a locking projection forms. A collapse of the survey in the indentation, ie a correct mounting position, is thus easily felt by turning the adapter. Conversely, the Aufsteckhilfe can also be designed as a survey, if this fits the inner contour of the adapter and in particular to the locking means, for example a locking groove.

In one embodiment of the invention can be provided that the latching projection has an aligned in an insertion direction, preferably on the inner surface attaching Rastvorsprung- starting slope. This can facilitate latching of the adapter to the housing.

In one embodiment of the invention can be provided that the counter-locking means is formed on the outside of the housing. Thus, the counter-locking means outside the flow path can be formed, so that unnecessary pollution spots are avoidable. In particular, it can be provided here that the counter-locking means is a counter-locking means starting slope having. This facilitates latching of latching means and latching means when connecting the adapter to the housing.

In one embodiment of the invention can be provided that the Strahlformeraufnahme is formed widening in the flow direction. This allows a sealing insertion of the adapter in the Strahlformeraufnahme even at Fertigungstole ^¬ tolerances of the adapter.

In one embodiment of the invention can be provided that the adapter is deformed at its inflow end in the inserted state by the Strahlformeraufnahme. Thus, a simple way is described, the adapter to lie close to the Strahlformeraufnahme. It is particularly favorable when the Strahlformeraufnahme is formed for this purpose divergently in flow direction ^¬. Thus, a desired deformation is easily reached when inserting the adapter in the Strahlformeraufnahme, for example, by the adapter is made with respect to the position assumed by him before the Strahlformeraufnahme and deformed dimension with oversize.

In one embodiment of the invention can be provided that the adapter has a voltage applied to the Strahlformeraufnahme sealing lip. Thus, a gap between the adapter and the Strahlformeraufnahme is easily sealed. It is particularly advantageous if the sealing lip is formed at an inflow-side end of the adapter. The advantage here is that no gap areas between the adapter and Strahlformeraufnahme from the flow path are accessible. Alternatively or additionally, it may be provided that the sealing lip is elastic. This allows a simple deformation of the adapter, for example, in the already described aufweitenden training of Strahlformeraufnahme. For example the elastic Dichtli rubber-free can be formed to prevent colonization of the sealing lip with bacteria or at least reduce.

Alternatively or additionally, it can be provided that the adapter preferably has a sealing ring resting against the jet former receptacle at its inflow-side end. Thus, a particularly tight conclusion can be achieved with simple means. Preferably, the sealing ring is held on one side or even on both sides axially on the beam former in order to hold the sealing ring when plugged into the Strahlformeraufnahme or even during insertion and withdrawal on the beam former. Thus, a water contact with the sealing ring, which may be made of rubber, tolerable because the sealing ring is always replaced with the Strahlformer. This can be ensured for example by a two-sided support on the beam former. Here, the sealing ring, preferably via a shoulder or at least one radially protruding projection, on one side (for insertion into or withdrawal from the Strahlformeraufnahme with the beam former) or, preferably via two oppositely directed and the sealing ring between them receiving shoulders or at least two radially projecting, axially spaced apart and / or the sealing ring receiving between them, projections on both sides (for insertion into and withdrawal from the Strahlformeraufnahme with the beam former) to be held axially. For example, the sealing ring can be made of rubber even if it comes in contact with water in use, as it is often replaced.

It is particularly advantageous if the sealing ring is preceded by a sealing lip formed on the jet former, for example as already described. Thus, the benefits of a Sealing lip, namely in particular the hygienic safety, with the advantages of a sealing ring, namely in particular the increased tightness, combined.

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

It can be provided that the adapter has a beam former, in particular a flow regulator or jet aerator. This allows the adapter to set a desired upper limit for a flow rate. Alternatively or additionally, the adapter may be formed as a ventilated adapter. A ventilated adapter allows the mixing of air to create a soft water jet. The adapter may also be additionally or alternatively, depending on the requirements with other functional units, such as a throttle, equipped.

It is particularly favorable if the latching means have at least two latching projections engaging the housing. This allows a secure hold in the fixed position with active locking. It can be provided that the locking means are formed on two opposite sides of the housing. Thus, a two-sided hold on the housing is reached, which - in a fixed position - allows a particularly secure hold of the adapter to the housing. It is for example a hold of the adapter even at high water pressures achievable.

It can thus be formed at least four locking means and / or matching counter-locking means. Corresponding can at least four handling projections are formed, which are best evenly spaced from each other.

In one embodiment of the invention can be provided that the counter-locking means have at least two locking recesses. Thus, a locking is possible at two spaced locations. Preferably, the counter-locking means are arranged on opposite sides of the housing. Here it is particularly advantageous if the latching means correspondingly also have two mutually opposite sides engaging on the housing latching projections.

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

Generally it can be said that it is convenient to distribute many different locking means in the circumferential direction. In this way, the most uniform possible maintenance of the sealing lip or the sealing ring can be achieved in the interior of the Strahlformeraufnahme. To reinforce the adapter, the already mentioned handling projections and / or other material reinforcements may be provided on the outside, for example, to increase a restoring force of the locking means.

In one embodiment of the invention can be provided that the inner surface between two circumferentially adjacent locking means describes a portion of a rotating body. The advantage here is that a rotary motion is easily feasible. Alternatively or additionally, it can be provided that the outer surface of the housing between a pair of counter-latching means adjacent to each other in the circumferential direction encloses a section of a rotor. describes body. Again, a simple guidance of a rotational movement is possible. , When the inner surface and the outer surface described in the aforementioned Abschnit ^¬ th the shape of a rotary body is particularly favorable. Thus, the inner surface and the outer surface can slide on each other to guide the rotational 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-side end of the flow path, wherein a mating thread of a fitting outlet can be screwed to the thread. The advantage here is that the housing is easy to Armaturenausläufen having a thread, can be fastened. The housing is therefore also replaceable.

In one embodiment of the invention can be provided that on the adapter a beam-changing inner part is ausgebil ^¬ det. Thus, the adapter can be equipped with a functionality with which a desired jet property, for example in degrees of air admixture, a cross-sectional shape, a flow velocity, an airfoil and / or a flow rate, is adjustable. It is thus by changing the adapter simply a desired functionality changeable or renewable. For example, the adapter can be designed in a structurally simple case as with a rule star. It is particularly favorable if the inner part is connected in one piece with the adapter.

In one embodiment of the invention can be provided that on the adapter a beam-changing inner part is detachably connected. The advantage here is that the adapter can be reusable when replacing the inner part. Also, therefore, has to be a lot of different Innenteils only a common adapter be kept. This simplifies storage. The beam-changeable inner part can be designed, for example, as an insertion cartridge and inserted into the adapter.

In one embodiment of the invention 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, by an angle which is enclosed by the insertion direction and the holding force receiving inclined surface, in particular wherein the angle is in the material and / or an angle of more than 90 ° indicates an oblique inclination of the locking means on the counter-locking means (or vice versa) ,

The invention also provides a sanitary fitting with a sanitary outlet device according to the invention, in particular as described above and / or according to one of the directed on a sanitary outlet device claims before, wherein the sanitary outlet device is screwed to a tap outlet of the sanitary fitting. The sanitary outlet device is therefore easy to retrofit. Alternatively, it can be provided that the housing of the sanitary outlet orrichtung is integrally formed on a fitting outlet of the sanitary fitting. The housing is thus not interchangeable or non-destructively removable arranged on the sanitary fitting.

A preferred use of possibly independent inventive quality of an adapter can provide that the adapter for forming a sanitary outlet device according to the invention, in particular as described above and / or according to one of the directed to a sanitary outlet device arrival claims, and / or a sanitary fitting according to the invention, in particular as described above and / or after the claim directed to a fitting, is used. The adapter can in this case have the representational and / or functional features of the adapter of the sanitary outlet device described above and / or in the following description of the figures. In particular, it can thus be provided that the adapter is transferred with a rotational movement between a fixing position and a releasing position. In particular, the adapter may be formed with a latching connection designed and constructed for producing a latching connection with a counter-latching means. It is favorable if the counter-latching means is oriented outwards and the latching means is oriented correspondingly inwards, for example on the already mentioned inner surface, in order to achieve the described advantages. The adapter can have a beam-changing inner part in the described manner, for example an insertable inner part.

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

In the following, FIGS. 1 to 5 will be discussed in the following together. wrote.

A designated as a whole by 1 sanitary outlet orrichtung has a housing 2. On the housing 2 a Strahltormeraufnähme 3 is formed on the inside.

In the Strahlformeraufnahme 3, an adapter 4 is used, which is in more detail to be described manner from the Strahlfor ^¬ meraufnahme 3 removable.

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 can form, for example, a control star, a jet regulator, a beam limiter and / or a beam former. This inner part 31 is inserted as insertion 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 insertion cartridge 32 is held by the stopper 34 in its use position.

The adapter 4 is locked to a fixing position according to Figure 2 with the housing 2 in a manner to be described in more detail. The adapter 4 can be transferred by a rotation in the position shown in Figure 3, in which the adapter 4 from the housing 2 and thus from the Strahlformeraufnahme 3 is removable. This position according to FIG. 3 is thus a releasing position of the adapter 4.

From an overview of the arrangements according to FIG. 5, FIG. 4 and FIG. 3, it can be seen that the adapter 4 can be inserted counter to a flow direction of the flow path 5 into the jet former receptacle 3. As far as the releasing position according to 3, the adapter 4, which constitutes a flow obstacle in the flow path 5, is forced out of the jet former receptacle 3.

In particular, from the completely drawn representation according to FIG. 1 and FIG. 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 a rotation axis 6, which is aligned along the flow path 5. By this rotation, the adapter 4 can be adjusted between the fixing position and the releasing position.

With regard to this axis of rotation 6, the fixing position according to FIG. 2 and the releasing position according to FIG. 3 are arranged at the same height. The axis of rotation 6 is in this case also an insertion 7 of the adapter 4 for insertion into the Strahlformeraufnahme 3 before, so that the fixed position and the releasing position are also arranged with respect to this insertion 7 at the same height. A transfer movement between the positions thus runs in an axial plane.

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

This contour 10 is formed in the embodiment by a flat 11 which interrupts an otherwise circumferential groove 12.

This ensures that upon rotation of the adapter. 4 about the axis of rotation 6 a locking means 13 which engages in the form of a locking projection ^¬ 14 in the groove 12 as a counter-latching means 15 latching ^¬ , is released in the region of the flattening 11. Once 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 locking means 13 is locked with the counter-locking means 15, the adapter 4 can not be removed, and the adapter 4 is fixed in the Strahlformeraufnahme 3. The adapter 4 itself is non-circular on the outside and has two diametrically opposed handling projections 16. At these handling protrusions, a user can easily grip the adapter 4 to rotate it about the rotation axis 6 between the fixing position and the releasing position.

In Figure 1 it can be seen that the groove 12 is limited as a groove portion 17 on a peripheral portion 18 of the housing 2. This limitation is given on two sides by a respective flattening 11.

In this way, the releasing position can be assumed in two positions offset by 180 °, since the latching means 14, which is likewise limited in the circumferential direction, can be pulled off the housing 2 via the flats 11.

This groove portion 17 thus forms a latching receptacle 19 for the latching projection 14. It can also be seen in FIG. 1 that the latching means 14 are formed on an inner surface 20 of the adapter 4. The inner surface 20 is formed without interruption circumferentially. This causes a particularly strong resistance to deformation of the locking projections 14 radially outward. Thus, the locking holds particularly well. The inner diameter and the inner circumference of this inner surface 20 are in this case matched to the outer diameter and the outer circumference on the outer side 8 of the housing, so that the inner surface 20 rests in latched, ie fixing, position on the outer side 8.

The inner surface 20 is thus supported between the latching projections 14 on the housing 2, whereby an increased strength of the latching is achieved. In order to facilitate latching when mounting the adapter 4, a latching projection run-on slope 21 is formed on the latching projection, which is aligned in the insertion direction 7 and which cooperates with a counter-latching starting bevel on the outside 8 in the region of the counter-latching means 15.

On the adapter 4 at least one access opening 35 is formed on the outlet side, via which a pointed tool can be inserted. Thus, for example, supported on the serving as a guide bevel 36 Gegenrastmittel starting slope or - in further embodiments - on a separate guide slope, the locking means 13 are brought without rotation of the adapter 4 from an engagement position with the counter-locking means 15 to subtract the adapter 4. The Strahlformeraufnahme 3 has an inner cone 23, through which it is formed in the flow direction, ie along the flow path 5, widening. The adapter 4 is dimensioned so that it is deformed by the inner cone 23 when inserted into the Strahlformeraufnahme 3.

For this purpose, the adapter 4 at its inflow end 24 has a circumferential sealing lip 25 made of an elastic, rubber-free material, for example made of plastic, which is deformed by the inner cone 23 radially inwardly. The sealing lip 25 is thus close to the Strahlformeraufnahme 3.

The inflow-side 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 may in this case be made of plastic and, for example, have a known, not further evident, flow regulator 26 or the like beam shaper, for example, a jet aerator behind a front screen 27 inside about at the point indicated by the arrow.

The adapter 4 may additionally or alternatively be designed as a ventilated adapter 4 in a conventional manner.

From the figures it is still apparent that the already mentioned inner surface 20 and the outer side 8 beyond the locking means 13 and the counter-locking means 15 each describe a portion of a rotating body.

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

In further embodiments, the housing 2 in at known manner have a thread which is screwed with a mating thread of the valve outlet 28.

FIG. 6 shows a further exemplary embodiment of a sanitary discharge device according to the invention. Functionally and / or constructively to the preceding embodiments, identical or identical components and functional units are denoted by the same reference numerals and not described separately again. The comments on the preceding exemplary embodiments therefore apply correspondingly to FIG. 6.

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

In the 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 further embodiments, the locking means 13 is formed as a locking projection 14 on the housing 2, while in the inner surface 20 corresponding groove portions 17 are formed to a locking receptacle 19 and thus a counter-locking means 15 to succeed. Here, too, it may be provided that corresponding contour run-on slopes 30 or other non-circular contours 10 are formed in the inner surface 20 in order to create a location in a section 9 in the circumferential direction of the inner surface 20 at which the Locking 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 former receptacle 3 form the fixing positions. In further embodiments, other known per se combinations of locking means and counter-locking means are realized.

Figures 7 to 9 show a further inventive embodiment of a sanitary outlet orrichtung. Functionally and / or constructively to the preceding embodiments, identical or identical components and functional units are designated by the same reference characters and not described again separately. The remarks on the preceding exemplary embodiments therefore apply correspondingly to FIGS. 7 to 9.

The exemplary embodiment according to FIGS. 7 to 9 differs from the preceding 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 in order to define a beam shape or beam quality deviating from FIG. 1. For this purpose, the insertion cartridge 32, as shown in FIG. 9, simply removed from the removed adapter 4 and replaced.

Figures 10 and 11 show a further embodiment according to the invention a sanitary outlet device. Functionally and / or constructively to the preceding embodiments, identical or identical components and functional units are denoted by the same reference numerals and not described separately again. The comments on the Approved embodiments therefore apply to the figures 10 and 11 respectively.

The exemplary embodiment according to FIGS. 7 to 9 differs from the preceding exemplary embodiments at least in that the housing 3 is formed separately from a fitting outlet 28. In this embodiment, a thread 37 on the housing 3 - here and often an external thread - with a matching mating thread 38 - here and often an internal thread - bolted to the fitting outlet 28. A in the use position on all sides of the material of the housing 3 and the valve outlet 28 enclosed seal 39 seals between the housing 3 and the fitting outlet 28. Both the housing 3 and the valve spout 28 are made of metal or other, a bacterial colonization aggravating or preventing material. The seal 39 may be made of rubber since contact with running water is practically impossible.

To replace the adapter 4 and / or the jet-forming inner part 31, the housing 3 may remain on the fitting outlet 28. FIGS. 11 to 14 show a further exemplary embodiment according to the invention. Structurally and / or functionally identical or identical components and functional units to the preceding exemplary embodiments are again designated by the same reference numerals and are not described separately again. The remarks on FIGS. 1 to 10 therefore apply correspondingly to FIGS. 11 to 14.

In contrast to the preceding embodiments has the adapter 4 on the outside four circumferentially uniformly distributed handling projections 16.

The locking means 13 and the counter-locking means 15 are in this case designed with undercuts, so that there is a release angle of more than 90 °.

The locking means 13 and the counter-locking means 15 have herizu to matching inclined surfaces 43 which define a release angle of the locking connection of more than 90 °. Each of the inclined surfaces 43 is thus employed in the insertion direction 7 against the respective corresponding inclined surface 43 such that a lateral deflection of the locking means 13 in a train on the housing 4 (and thus at a pressure load due to the water pressure) is mechanically prevented. The release angle thus causes a hooking of the locking means 13 with the counter-locking means 15th

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

In this embodiment, the insertion cartridge 32 is composed as a beam shaper 26 of a Zerlegerteil 45 and an outlet part 47. The sealing lip 25 protrudes here against the flow direction of a main body of the outlet part 47.

The outlet part 47 may in this case be formed integrally with the adapter 4 or inserted into it.

FIGS. 15 to 21 show a further embodiment according to the invention. Constructive and / or functional to the previous exemplary embodiments identical or identi ^¬ cal components and functional units are again denoted by the same reference numerals and not described separately again. The statements relating to FIGS. 1 to 14 therefore apply correspondingly to FIGS. 15 to 21.

The exemplary embodiment according to FIGS. 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. Its hidden position does not flush the O-ring even though it comes into contact with water.

The beam shaper 26 is again composed of a Zerlegerteil 45 and an outlet part 47. The outlet part 47 may be integrally connected to the adapter 4, or the outlet part 47 is held by the adapter 4.

At the outlet part 47 and the Zerlegerteil 45 each have a circumferential shoulder 46 is formed, which receive the sealing ring 40 between them and hold it axially on both sides. Thus, the sealing ring 40 can be used with the adapter 4 and removed again. In further embodiments, instead of the shoulders 46 radially projecting projections are formed, which hold the sealing ring 40 in sections axially.

In 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 corresponding to the locking means 13).

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

The counter-locking means 15 are arranged upstream in the insertion direction 7 Aufsteckhilfen 41, which here have the shape of indentations 42. The locking means 13 are in this case dimensioned so that they are slightly bent by the cylindrical portion of the housing 2. Thus, a user can easily feel when the latching means 13 fall in a rotation of the adapter 4 in the peripheral region of the indentations 42. This thus constitutes a plug-in aid 41, since the latching means 13 are now aligned with respect to the (in this position by the adapter 4 may already be hidden) counter-latching means 15 and simply plugged onto this.

In the sanitary outlet device 1 is thus generally proposed to form a Strahlformeraufnahme 3 on a housing 2, in which an adapter 4 removably inserted and rotatably disposed about its axis of rotation 6, wherein the adapter 4 between a fixing position, in which the adapter 4 against a removal is secured, and a releasing position in which the adapter 4 is removable, can be rotated.
