Description

BEAMED FAN WITH DETACHING MECHANISM

The invention relates to a sanitary outlet fitting with a water outlet and a, associated with the water outlet jet regulator, which has a jet regulator housing with befindli fitting parts, which Strahlreglergehäuse by means of an axial insertion movement m the water outlet is used and a holder with at least one radially movable Having projection for connecting to the water outlet.

Overall aerator or built-in parts of such aerators must be replaced from time to time because of wear, contamination and / or calcification and also for hygienic reasons.

Usually, jet regulators are located in a housing which can be screwed into and out of an outlet fitting, wherein attack points for a tool are provided on the jet regulator housing. The replacement of the jet regulator thus requires tools and some knowledge of the Bedienpersonais. In facilities where a variety of such aerators are installed, such as hotels, clinics and toilet facilities, so the maintenance is relatively expensive overall.

From DE 38 17 270 A1, a sanitary outlet armature with a jet regulator is already known, which has a jet regulator housing, which can be used by means of an axial insertion movement m a mouthpiece. At the, different mounting parts in receiving jet regulator housing, a holder is provided, which the jet regulator housing in the mouthpiece m normal- can fix operation position and releases when a predetermined back pressure exceeds such that the jet regulator either falls out of the jet regulator housing or enters a release position in which, for example, around the jet regulator around the total passage cross-section enlarging annular channel is formed. The holder of the previously known jet regulator has configured as a spring clip, radially movable projections which carry at their free ends locking ribs which engage in a circumferential annular groove in the jet regulator housing. The previously known jet regulator can also be used in backflow-sensitive devices, such as in particular instantaneous water heaters, which otherwise tend to damage and malfunction when a predetermined back pressure is exceeded. A simpler and faster assembly and disassembly is not intended with the previously known jet regulator contrast.

Object of the present invention is therefore to provide a sanitary outlet fitting of the type mentioned, in which rather the jet regulator is securely held in the water outlet and can be mounted and dismantled very easily and quickly.

The solution to this problem according to the invention, in the case of the resonant outlet fitting of the type mentioned in the introduction, is that either an externally actuated locking element is provided for selectively securing and releasing the holder, or that an unlocking tool is provided, which by means of an axial insertion movement in the annular space provided between the water outlet inner circumference and the housing outer circumference is insertable, wherein this insertion movement of the unlocking tool into a radial movement of the at least one projection of the holder of a ner functional position can be implemented in an unlocked position.

The jet regulator used in the water outlet of the outlet fitting according to the invention can be easily and conveniently mounted with a mere finger pressure. If this jet regulator is used, for example, in areas where unauthorized manipulation of the water outlet and theft of the jet regulator are not to be feared, a locking element operable without tools for selectively securing and releasing the holder can be provided. If, on the other hand, the jet regulator is also to be used in the public sector for tampering and theft prevention, an unlocking tool can be provided instead which can be introduced by means of an axial insertion movement into the annular space provided between the water outlet inner circumference and the outer circumference of the housing, this insertion movement of the unlocking tool m, a radial movement of the at least one projection of the holder from a functional position m to an unlocking position can be implemented. Thus, in this alternative, essentially only an axial insertion movement with the aid of the unlocking tool is required to disassemble the jet regulator used in the outlet fitting according to the invention from the water outlet.

In both alternatives provided according to the invention, the replacement of the jet regulator can be carried out in a simple manner by auxiliaries, for example cleaning personnel, who only have knowledge of the simple handling. After removal of the jet regulator, this total or its built-in parts can be exchanged.

Furthermore, it is advantageous that an exchange process of Beam controller is much faster than before. This is particularly important where, for reasons of hygiene, a frequent, possibly even daily change of the jet regulator is prescribed in order to carry out a disinfection measure, such as, for example, an autoclave disinfection.

A particularly secure fixing of the jet regulator in the water outlet is achieved if the at least one, radially movable projection m for engaging, is located in the water outlet recess formed.

The inventively designed jet regulator can m the water outlet of a specially adapted to him outlet fitting are used. If the jet regulator designed according to the invention is also used in conjunction with commercially available outlet fittings, it may be expedient for the water outlet to be designed as an adapter mouth piece or mouthpiece which is preferably detachably connectable to an outlet fitting.

Optionally, the adapter mouthpiece may be provided with an inner recess as part of the detent holder for receiving the jet regulator housing, wherein the adapter mouthpiece is connectable to an outlet fitting. It is expedient here if the adapter mouthpiece has a connection thread for connection to the outlet fitting.

The jet regulator provided according to the invention can therefore be used both directly in a suitably designed outlet fitting and with the aid of the adapter mouthpiece on traditional fittings with screw-in thread for a conventional discharge screw regulator. For this purpose, the adapter mouthpiece is screwed once to the outlet fitting. Thus is also one easy retrofitting existing fittings and a conversion to the inventively provided jet regulator possible.

Preferably, the holder is a latching holder with preferably several resilient latching projections.

As a result, the jet regulator is held in a predetermined position with the locking element m when it is inserted into the mouthpiece even before securing.

Conveniently, the recess m the mouthpiece is an inside in the mouthpiece preferably circumferential annular groove.

The fitting processing for receiving the jet regulator is thereby simplified, since the annular groove is much easier to bring than a teach-containing thread and in the annular groove a large tolerance field is permitted. A circumferential annular groove has the advantage that the jet regulator m arbitrary rotational position can be used.

The jet regulator housing expediently has a latching projection on the outside, which is approximately radially resilient and engages in the mounting position m the annular groove of the mouthpiece forming an inner recess, wherein the locking element is designed to be displaceable for blocking and releasing the compression movement of the latching projection.

During axial insertion of the jet regulator m, the mouthpiece of the locking projection is spring-loaded radially inwardly from the wall of the mouthpiece until it m assembly position m, the inner recess of the mouthpiece or the like receiving part engages and thus determines the jet regulator. To block the latching holder and to secure the jet regulator, the locking element is then pressed in, so that the latching projection is locked is and even during operation under the pressurization of the liquid flow accidental ejection of the jet regulator is reliably avoided.

To remove the jet regulator, the locking element is pulled out a piece and the jet regulator can then be removed.

According to a practical embodiment of the invention, the jet regulator housing has on the outside, in particular distributed on the circumference, as part of the detent holder, lamellar spring elements located at the free end regions, outwardly facing latching projections. In this case, the locking element is connected relative to the housing axially displaceable with this and supports in the securing position, the spring elements inside.

The circumferentially distributed and, for example, also elliptically configured spring elements can yield comparatively easily when mounting the jet regulator, so that the insertion of the jet regulator housing into the outlet pipe of the outlet fitting can be made smoothly. Subsequently, the locking element is inserted, so that then the spring elements are fixed and thereby can no longer emfedern.

In the jet regulator housing as a built-in parts expediently a jet disintegrator and one or more parts are provided for beam conditioning. These are the wear parts that have to be replaced from time to time, in particular due to calcification and also for hygienic reasons.

Preferably, the jet regulator is inserted directly into the mouthpiece of the used and connected with this through the locking bracket. As already mentioned, there is also the possibility that a connection adapter is provided with an inner recess, for example an annular groove as part of the latching holder for receiving the jet regulator housing, and that the connection adapter can be connected to the mouthpiece of the outlet fitting. In this case, a conventional outlet fitting can be used, for example with a connection thread, in which case the connection adapter has a matching connection thread.

An embodiment of the invention provides that the jet regulator housing is part of the jet breaker and that its sleeve-shaped housing has the spring elements with the latching projections. As a result, the number of parts of the jet regulator is reduced, thus simplifying the structure. Among other things, no axial seal is required in this embodiment, since the jet separator housing is combined with the jet regulator housing, so consists of one piece.

Due to the reduction of the parts, more installation space is available, so that advantageously the hook elements of the annular locking element can point outwards and engage in slot-shaped recesses of the jet regulator housing.

It is advantageous if the locking element has an inside smooth, closed surface.

As a result, a Kalkansatz is counteracted at the coming into contact with water inside of the locking element. In addition, the outwardly facing hook elements are sealed off by this wall of the locking element, so that Here a Kalkansatz is largely prevented. Thus, a functional impairment of the locking element by lime and thus the disassembly is significantly improved.

Conveniently, the provided for locking connection of the Vemegelungs- elements and the jet regulator housing annular groove is dimensioned larger in width than the width of the associated annular bead.

As a result, production-related fluctuations in the height of the chamfer and the position of the annular groove can be compensated in the mouthpiece, without affecting the safety of the attachment.

According to another, particularly simple embodiment of the invention, the jet regulator housing spring elements with outwardly projecting locking projections for direct engagement in an annular groove or the like recess of the mouthpiece, wherein the locking projections are simultaneously the locking elements or locking elements.

Appropriately, are two diametrically opposite

Spring elements provided with latching projections, which provide sufficient support of the jet regulator m a mouthpiece. In this case, the jet regulator housing and the spring elements with the latching projections downstream a flange-like, outwardly facing handle approach.

This jet regulator can also be mounted and dismantled without tools. For assembly, the jet regulator is pressed, for example with the flat hand m, the fitting mouthpiece. For disassembly, the two lateral, inwardly elastically yielding locking elements are pressed together with two fingers on the handle lugs and the jet regulator can then be pulled out. According to one embodiment of the invention, the latching elements on latching surfaces which extend obliquely with an undercut to the cross-sectional plane of the jet regulator.

As a result, a lock is formed, which must be solved before removing the jet regulator. For this purpose, the jet regulator is first inserted slightly axially inwards, thereby releasing the lock. The locking elements are then pressed together on the handle lugs so that they come out of engagement and the jet regulator can be removed.

Instead of locking by means of the undercut latching surfaces on the latching elements, other latching elements can also be provided for releasably blocking the latching projections against interference.

According to a further embodiment of the invention, the jet regulator housing having a holder with releasable from an anchoring position, spring-loaded in the locking direction Verhakungselementen for engaging on the inner wall of the mouthpiece, wherein a push-in and unlocking on the one hand for Einsetzbeaufschlagung the jet regulator housing and on the other hand to unlock the Verhakungselemente is provided.

By Verhakungselemente no Gegeneinformungen are required in the mouthpiece into which this jet regulator is used. The mouthpiece can thus be used as this unprocessed pipe.

At most, it can be helpful for a particularly good anchoring, if the inner wall of the mouthpiece has a rough surface. It is expedient if the wall of the Emschub- and unlocking is formed in cross-section approximately Z-shaped with a paragraph and if provided in the region of this paragraph passage window for the located on the annular jet regulator housing interlocking elements.

During installation, the jet regulator is pushed in by simply pressing in a mouthpiece by hand, the insertion force being transmitted via the annular insertion and unlocking element to the likewise annular jet regulator housing with the jet separator located therein. The paragraph located on the Emschub- and unlocking, formed by the Z-shape paragraph lies on the front side of the Verhakungselemente having jet regulator housing.

The jet regulator is then held in the final assembly position by the interlocking elements which are supported on the mouthpiece inner wall and spring-loaded to the outside.

For disassembly, the Emschub- and unlocking at its downstream end a flange-like, outwardly facing Griffansätz projecting beyond the lower end of the mouthpiece. At this is pulled for disassembly, wherein the Z-shaped cranked Emschub- and unlocking meet with the upper edges of the passage window on the inclined interlocking elements and adjust them slightly inward or at least reduce their pressure force, so that the removal of the jet regulator from the mouthpiece is possible.

A preferred development according to the invention of its own worth-worth protection provides that the holder m on both sides open housing pockets of the jet regulator housing axially displaceably guided spring elements, which at their each free spring element ends have one, in the functional position of the jet regulator via a housing pocket opening radially projecting locking projection. In this further embodiment, the holder has axially displaceably guided spring elements. These spring elements are guided in both sides open housing pockets of the jet regulator housing and have at their free spring element ends in each case a locking projection on the functional position of the jet regulator via a housing pocket opening radially projecting such that the jet regulator housing securely and firmly held in the water outlet is.

It is particularly advantageous if the opening edge of the housing pocket opening is formed as a locking element which acts on the latching projection having free portion of at least one spring element m functional position of the jet regulator such that the over the housing pocket opening radially projecting projection of the at least one spring element is secured in the recess of the water outlet. In this embodiment, the locking projection having free spring element end is acted upon in the functional position of the jet regulator from the opening edge of the housing pocket opening and supported that this spring element end can not rebound from the recess of the water outlet especially at, for example, flow-increasing pressure.

In order to solve the jet regulator housing from the water outlet and to be able to dismantle the jet regulator, it is advantageous if by a relative displacement of jet regulator housing and holder the m case pockets guided spring elements are displaced so that provided on the spring elements locking projections in one in the Housing pockets radially inward returnable unlocked position are movable. By a mere relative movement of the jet regulator housing and holder, for example by moving the jet regulator housing m the water outlet while retaining the back of the holder, the pressure exerted by the opening edge of the Gehäusetaschen- opening pressure on the free spring clip ends is released so that the spring clips m retract the housing pockets and can move into their unlocked position. If the spring clips are in their unlocked position, the jet regulator housing can be pressed out of the water outlet, for example, by the pressure of the water flowing to the water outlet.

In order to be able to move the spring elements located m the housing pockets at the same time, it is advantageous if the holder has an annular handle attachment on which the spring elements protrude in the shape of a crown.

A preferred and structurally particularly simple embodiment according to the invention provides that each housing pocket has two housing pocket openings, of which a first housing pocket opening is provided on the downstream end edge of the jet regulator housing and a second housing pocket opening on the housing outer circumference ,

In an alternative in which an unlocking tool is provided, it is advantageous if the spring elements provided on the outside of the jet regulator housing are oriented with their free end regions to the inflow side of the jet regulator. If the free end regions of the spring elements are oriented toward the inflow side of the jet regulator, these free end regions can be acted upon more easily from the outflow side of the water outlet and radially inward into their unlocked position move.

So that in the unlocked position of the spring elements no residual latching resistance between the jet regulator housing and the water outlet has to be overcome, it is advantageous if the spring elements can be moved back with the aid of the unlocking tool within the enveloping circle defined by the largest housing diameter.

The jet regulator housing can also be removed from the water outlet with the aid of the unlocking tool if the jet regulator housing and the unlocking tool can be detachably coupled together. In this case, a preferred embodiment according to the invention, that the jet regulator housing and the unlocking tool are releasably latched together and that of jet regulator housing and unlocking tool has a part at least one locking projection and the other part has at least one latching recess.

In order to be able to detach the connection provided between the jet regulator housing and the unlocking tool and to be able to separate the jet regulator housing from the unlocking tool in a simple manner, it is advantageous if the inflow-side subarea of the jet regulator housing in the coupled or latched position thereof is unlocked via the unlocking tool Unlocking tool protrudes. Thus, the jet regulator housing can be detected at its over the unlocking tool protruding portion and the connection provided between the jet regulator housing and unlocking tool connection can be overcome by hand.

FIG. 35 shows the jet regulator from FIGS. 30 to 34 removed from the water outlet and still located on the unlocking tool.

A shown in FIGS. 1 to 4 beam regulator 1 is shown in FIG. I and 2 used in a tubular adapter mouthpiece 2, which in turn is connectable with its connecting thread 30 with a sanitary outlet fitting, not shown.

The jet regulator 1 has a housing 3 with embrasures located therein. In the embodiment shown, a jet splitter 4 and a front screen 5 can be seen as built-in components.

The connection between the jet regulator 1 and the mouthpiece 2 by means of a catch holder 6. This allows the jet regulator from the outlet side 7 of the mouthpiece 2 m this is inserted and latched. With the aid of a locking element 8, the latching connection is secured, so that on the one hand smooth insertion and removal of the jet regulator is possible, but on the other hand a secure hold m working position is given, so that even high flow pressures can be intercepted.

The jet regulator housing 3 is shown in FIG. 5 on one side in a perspective view in an unlocked position, and it can easily be seen that the housing, distributed around the circumference, projects towards the outside with male-shaped spring elements 9 with end regions facing the free, m flow direction wide latching projections 10 has. The spring elements 9 are part of the outer wall 14 of the housing 3. In Fig. 5 is clearly visible that the adjacent spring elements 9 by axial slots

I 1 are separated so that they can insert easily.

The latching projections 10 have in the axial direction on both sides bevels 12 in order to simplify the insertion of the jet regulator into the mouthpiece 2 and also to remove the jet to allow controller with unlocked locking element 8. The locking projections 10 engage in functional position of the jet regulator 1 in an inner annular groove 13 of the mouthpiece 2 a. The cross-sectional shape of this annular groove 13 corresponds approximately to the cross section of the locking projections 10. When inserting and removing the jet regulator 1, the snap-in projections 10 located on the spring elements 9 spring slightly radially inwardly along the arrow Pf 1 in FIGS. 3 and 4 when inserting in functional position m, the annular groove 13 back.

The annular locking element 8 is displaceable in the axial direction m and connected to the housing 3 of the latching holder 6. In the figures 1,2, the locking element 8 m blocker position and m is the figures 3,4 and 5 in partially pulled-release position.

As can be seen in FIGS. 1 to 5, the jet regulator housing 3 is of double-walled design in certain regions and has a coaxially arranged annular sleeve 15, which is spaced inwardly from the outer wall 14. Between this and the outer wall 14, an annular gap 16 for the axially displaceable, annular locking element 8 is formed. As a result, the locking element 8 is guided in the axial direction and can also be supported on the back of the annular sleeve 15 in the locking position.

The annular sleeve 15 also forms a receptacle for the jet splitter 4 and has at the inflow end a support shoulder 17, on which the jet splitter 4 rests with an annular flange 18.

The locking element 8 can be moved axially between the locking position shown in FIGS. 1 and 2 and the release position shown in FIGS. 3 to 5. The locking element has an outer, circumferential annular bead 20, which engages in the locking position m an inner side provided on the spring elements 9 and the locking projections annular groove 19. In the unlocking direction, the two locking projections 19, 20 have inclined surfaces, so that the locking element 8 can be moved comparatively smoothly in the release position.

The annular groove 19 is designed to be wider in the axial direction than the annular bead 20, so that the locking element 8 can compensate for positional differences of the groove 13.

The unlocking movement of the locking element 8 is limited by hook elements 21. The hook elements 21 engage in recesses 22 of the annular sleeve 15 and lie m release position at the downstream boundary surfaces 23 at. Thus, the housing 3 and the locking element 8 are captively connected to each other. In addition, the locking element 8 m in the release position forms a good manual Haltemög- ability to pull the jet regulator 1 from the mouthpiece can.

The hook elements 21 thus form m connection with the downstream boundary surfaces 23 of the recesses 22 a displacement stop m withdrawal direction and m insertion position is a stop between the front ends of the hook elements and the transition between the outer wall 14 and the annular sleeve 15 is given in the insertion direction. In addition, the locking element 8 rests with a handle attachment 24 on the outer edge of the mouthpiece.

The handle attachment 24 provided at the outflow end of the locking element 8, which extends approximately radially outwards. is formed and in the locking position (Fig. 1 and 2) projects beyond the lower edge 44 of the mouthpiece 2, simplifies the manual grasping and pulling out of the locking element 8 when unlocking.

The jet regulator housing 3 has on the inflow side inwardly facing latching projections 25 for a retaining ring 26. This retaining ring 26 is used to set the built-in parts, ie the jet separator 4 and the adjoining adjoining screen 5. The retaining ring 26 acts on an O-Rmg 27, which in turn rests on the upper edge of the beam breaker 4. Furthermore, the jet regulator housing 3 has on the outside an annular groove 28 for a sealing ring 29, which provides a seal between the inner wall of the mouthpiece 2 or the like and the housing 3.

FIGS. 6 to 9 show another embodiment of a jet regulator 1a, in which the jet regulator housing 3a is part of the jet breaker 4. Its sleeve-shaped housing has the spring elements 9 with the latching projections 10. The Vernegelungselement 8a is annular and has in this embodiment, outwardly facing hook elements 21, the m slot-shaped recesses 22a of the jet regulator housing 3a, which is also the housing of the jet separator 4, a.

In particular m Figs. 6 and 7 is clearly visible that the annular locking element 8a has an inside smooth, closed surface. By pointing outward hook elements 21, these are outside the water flow and are thus well protected against calcification. Even with an overall stronger calcification of the jet regulator thereby these functional elements remain common, so that even in a strongly calcified state the dismantling of the jet regulator is maintained.

The combination of the jet separator housing and the jet regulator housing 3a reduces the number of parts. In addition, because of this one-piece design no additional axial seal as a two-part design required.

Also in this embodiment, a locking connection between see the locking element 8a and the jet regulator housing 3a is provided. In this case, an annular bead 20 is provided on the outside of the locking element 8a, and an annular groove 19 is provided on the inside of the hook element 10. Good to see m this exemplary embodiment that the annular groove 19 is slightly wider, so that production-related fluctuations in the height of the phase and the position of the annular groove 13 m the mouthpiece 2 can be compensated without the safety of the attachment is impaired ,

In Fig. 8 and 9 can still be seen that the jet regulator housing 3a distributed on the circumference has axial slots 11 in order to promote a smooth running of the spring elements 9.

10 to 17 show a further embodiment of a jet regulator 1b according to the invention, whose jet regulator housing 3b, 3c spring elements 9a with outwardly projecting locking projections 10a for direct engagement in an annular groove 13a of the mouthpiece 2a has. In this case, the latching projections 10a simultaneously form the locking elements, so that a locking element formed as a separate part is not required here.

In the embodiment, two diametrically opposed Spring elements 9a mxt locking projections 10a provided. These spring elements 9a with the latching projections 10a are integrally connected with their side facing away from the outflow 7 of the jet regulator side with the jet regulator housing wall and separated by lateral slots of the adjacent housing wall. On the outflow side, a flange-like, outwardly pointing handle attachment 24a adjoins the jet regulator housing 3b. In the area of the spring element 9a with the latching projections 10a, the handle projection 24a is separated by the lateral slots 45, so that the part of the handle projection 24a connected to the spring element 9a can be pressed with the fingers for radial embossing of the latching projections 10a. The remaining area of the handle attachment 24a, which is connected to the housing 3b, also serves to withdraw the jet regulator 1b from a mouthpiece 2a (see FIGS. 12 and 13).

It can be clearly seen in FIG. 11 that the latching projections 10a m have bevels 31 passing over the outside of the housing. When inserting the jet regulator 1b in a mouthpiece meet this run-up slopes 31 on the inner edge of the mouthpiece and m further inset this further radially inward until the locking projections 10a m the circumferential annular groove 13a radially outwardly engage. The latching projections 10a are arranged with their latching surfaces 32 spaced from the downstream edge 33 of the housing 3b or to the handle extension 24a, so that the housing 3b with his handle approach 24a down still so far out that it can be taken to unlock and pull out.

The function of a locking element take over in the present embodiment, the provided with an undercut locking surfaces 32, the m corresponding counter-formed imprints of the annular groove 13a engage. The undercut is like that designed that for unlocking the beam regulator 1b this first raised slightly while m the mouthpiece must be slightly inserted until the undercut is free, so that then the locking projections 1 Oa can be unlocked by radial impressions of the associated portion of the handle extension 24a. Subsequently, the jet regulator 1b can be taken down from the mouthpiece.

In the detail view according to FIG. 13a, an inwardly projecting positiomock 36 for a beam splitter 4 to be used is still recognizable. As a result, the jet splitter 4 can be used in the correct position m the housing 3b.

According to Fig.10 to 13, the sealing of the jet regulator 1b relative to the mouthpiece 2a by means of a radial seal with an O-Rmgnutflansch 35, which is located on the beam splitter The O-Rmgnutflansch 35 with the sealing element therein is on the inflow side on an annular end face 34 of the jet regulator housing 3b. It is useful if the end face 34 connected to the beam splitter 4, preferably ultrasonically welded.

14 to 17 show a further embodiment in which the jet regulator housing 3c has at its upstream end an outside annular groove 46 with annular seal 47 located therein for radial sealing against a mouthpiece 2a. The housing 3c is continuously formed as a sleeve with a mnenseitig smooth, closed surface. In this sleeve-shaped jet regulator housing 3c of the jet splitter 4 is used. The connection and sealing between the jet regulator housing 3c and the used beam splitter 4 can be done by a joining process, for example by ultrasonic welding. This is done in the area of an overlay ter 48 and the inflow-side end face of the jet regulator housing 3c. Also in this embodiment, the latching and locking elements are sealed off from the water flow, so that a calcification susceptibility is substantially reduced.

16 clearly shows that the wall of the jet regulator housing 3c has an inwardly closed recess 42 in the region of the spring elements 9a, with an outer side 43 spaced apart from the spring element 9a by at least the compression travel of the spring element. On the one hand, this provides enough spring-insertion space for the spring elements 9a with their latching projections 10a, and on the other hand, an inwardly closed wall is also present in this region.

FIG. 18 shows a bottom view, corresponding to the embodiment variants according to FIGS. 1 to 7 and FIGS. 19 to 21, of a jet regulator 1, 1 a, 1 c.

A further embodiment variant of a jet regulator 1c according to the invention is shown in FIGS. 19 to 21. This

Jet regulator 1c has an annular jet regulator housing 3d with a holder 6a which has hooking elements 37 releasable from an anchoring position and springing out in the direction of locking to engage the inner wall 38 of the mouthpiece 2b.

Furthermore, a start-up and unlocking element 39 is provided on the one hand for applying the jet regulator housing 3d and on the other hand for unlocking the hooking elements 37. In FIGS. 19 and 21 it can be seen that the wall of the push-pull and unlocking element 39 is approximately Z-shaped in cross-section with a shoulder 40. Within the scope of paragraph 40, at the periphery of the push-on and unlocking element 39, passage window 41 is provided for the hooking elements 37, wherein in the release position they pass through the passage windows 41 from inside to outside.

The tab-shaped hooking elements 37 project obliquely outward beyond the outflow-side edge 50 of the annular housing 3d. When the jet regulator 1c is inserted into a mouthpiece 2b, the interlocking elements 37 spring somewhat radially and fix the jet regulator 1c within the mouthpiece by pulling against it. In this case, the outer edges 51 of the hooking elements 37 are supported on the inner wall 38 of the mouthpiece 2b. In this embodiment, no annular groove or the like is required within the mouthpiece 2b. It suffices the usual roughness of the inner wall to allow a secure mounting of the jet regulator. In the exemplary embodiment shown, the mouthpiece 2b accommodating the jet regulator 1c has an internal insertion stop 49 for the jet regulator 1c.

The interlocking elements 37 simultaneously form latching elements and locking elements. For unlocking the annular and in the longitudinal section of its wall about Z-shaped insertion and unlocking element 39 on its handle projection 24b, which is preferably slightly above the lower mouthpiece edge 44, detected and pulled out so far that the hooking elements 37 from the inner Upper edges of the passage window 21 are acted upon and spring slightly radially. The jet regulator 1c located in the mouthpiece 2b is then released and can be removed from the mouthpiece 2b.

When inserting the jet regulator 1c, the insertion force is transferred via the insertion and release element 39 to the annular jet regulator housing 3d, wherein the Z-shaped shoulder 40 rests on the lower edge 50 of the housing 3d. The inner end faces of both the push-in and unlocking 39 and the housing 3d are on the underside of the O-Ringnutflansch 35 of the beam breaker 4, so that it is also taken on insertion, until it rests against the inner insertion stop 49 of the mouthpiece 2b.

At least the interlocking elements 37, optionally the entire jet regulator housing 3d can be made of metal, preferably spring steel.

In the embodiment, the jet regulator 1c is held against the insertion stop 49 within the mouthpiece 2b. But it is also possible to provide a connection between the beam splitter 4 and the housing 3d by clawing the housing with locking elements with the beam splitter. On a clawing of the two parts or an insertion stop can be omitted if the jet splitter 4 and the housing are made as a hybrid component of plastic and metal.

FIGS. 22 to 29 show a jet regulator 1 which has a jet regulator housing 3 with built-in components therein. From FIGS. 22 to 29 it is clear that in the jet regulator housing 3 here a jet splitter 4 is provided with a front screen 5 arranged on the upstream side. The jet regulator housing 3 of the jet regulator 1 shown in FIGS. 22 to 29 can also be inserted into the water outlet 2 of a sanitary water outlet fitting by means of an axial insertion movement.

In Fig. 22 it is indicated that the jet regulator housing 3 directly into the tubular outlet end of a to the jet regulator. 1 used adapted outlet fitting or by means of the jet regulator associated adapter mouthpiece 2 'can be mounted on a standard outlet fitting. While the left half of the drawing m Fig. 22 represents a water outlet 2, which is designed as a discharge end of a specially adapted to the jet regulator 1 outlet fitting, in the right half of the drawing of Fig. 22, an adapter mouthpiece 2 'is shown, with an inner or - As here - an external thread 30 are attached to the outlet end of a commercial outlet fitting and can accommodate the jet regulator 1.

The jet regulator housing 3 has a holder 6 for connection to the water outlet 2. For this purpose, the holder 6 has a plurality of spring elements 9 arranged in pairs on opposite sides of the jet regulator housing 3, each of which carries a latching projection 10 on its free and obliquely outwardly oriented spring element ends on the outside. The holder 6 is configured crown-shaped and has an annular handle lug 60 on which the spring elements 9 protrude. The spring elements 9 are guided axially displaceably in the housing pockets 63 of the jet regulator housing 3. These housing pockets 63 are open on both sides and have two housing pocket openings 62, 71, of which a first housing pocket opening 71 is provided on the downstream end edge of the jet regulator housing 3 and a second housing pocket opening 62 on the housing outer circumference.

24 and 25 it can be seen that the spring elements 9 abut the axial insertion of the jet regulator housing 3 in the water outlet 2 with the measures provided for the free spring element ends locking projections 10 on the inner circumference of the water outlet 2 'until these locking projections m a on the inner circumference of the water outlet 2 'and provided here as a circumferential annular groove 13 lock formed recess. In the now following and in Figs. 26 and 27 shown in more detail functional position, the jet regulator housing 3 moves inside on the latching projections 10 supporting spring arm ends in the direction of the water outlet 2 ', until the inflow-side opening edge 61 of the peripheral housing pocket openings 62 so applied to the free end portion of the spring elements 9 on its side facing away from the locking projections 10 and supported so that the further projecting beyond the housing pocket openings 62 locking projections 10 m of the annular groove 13 of the water outlet 2 'are secured. It is a particular advantage of the jet regulator 1 shown in FIGS. 22 to 29 that the opening edge 61 of the housing pocket openings 62 serving as locking element 8 is pressed more strongly against the spring elements 9 with increasing water pressure, and thereby, under the pressure of inflowing water, a self-reinforcing jamming of the spring elements 9 in the functional position of the jet regulator 1 results.

If the jet regulator 1 at the appropriate time from the water outlet 2 'are removed, the locking of the jet regulator housing 3 in the water outlet 2' by mere finger pressure on the jet regulator housing 3 can be solved. As shown in FIGS. 28 and 29, there is a relative movement of jet regulator housing 3 on the one hand and spring element 9 or the inner circumference of the water outlet 2 'on the other hand, which causes a displacement of the spring elements 9 guided in the housing pockets 63. the latching projections 10 provided on the spring elements 9 are moved into an unlocking position which is returned radially inwards into the housing pockets 63. The spring elements are 9 m stretched the housing pockets 63 and their free end portion through the downstream opening edge 64 of the housing pocket openings 62nd subjected to such that with the spring element ends and the latching projections 10 provided thereon move radially inwardly. In this unlocked position, the latching projections 10 come out of the annular groove 13 disengaged, so that the jet regulator 1 together with its jet regulator housing 3, for example, by the pressure of the incoming water from the water outlet 2 'move.

The m Fig. 1 to 29 shown jet regulator designs can be mounted and dismantled easily without tools. In such areas of life that are accessible to the general public, however, it may be expedient if the jet regulator 1 vandalism and theft in the water outlet 2, 2 'is arranged, without thereby the assembly and disassembly of the jet regulator 1 much more expensive designed .

The jet regulator alternative illustrated in FIGS. 30 to 35 therefore shows a jet regulator 1 to which an unlocking tool 65, which is shown in more detail in FIGS. 31 to 35, is assigned. The jet regulator 1 also has a jet regulator housing 3 with built-in components therein. For example, it can be seen in FIG. 30 that a jet splitter 4 is located in the jet regulator housing 3, to which a front screen 5 is connected upstream.

The jet regulator housing 3 of the jet regulator 1 shown in FIGS. 30 to 35 can likewise be inserted by means of an axial insertion movement into the water outlet 2 of an outlet fitting (not shown). The jet regulator 1 has at its jet regulator housing 3 to a holder 6 with at least one radially movable projection 10 which is intended to connect to the water outlet 2. As part of this detent holder 6, a plurality of spring elements 9 are provided which carry at their free end portions outwardly facing locking projections 10. These spring elements 9 are preferably evenly distributed over the outer circumference of the jet regulator housing 3, wherein the spring elements 9 associated with each other in pairs and can be diametrically opposed to each other. The spring elements 9 of the jet regulator 1 shown in FIGS. 30 to 35 are oriented with their free end regions to the inflow side of the jet regulator 1. The locking projections 10, which are initially radially deflected during the axial insertion movement, engage in the annular groove 13 forming a depression on the water outlet 2 as soon as the jet regulator 1 has reached its functional position.

In the detailed representation m Fig. 34 it can be seen that on the outer circumference of the jet regulator housing 3 m insertion direction above the spring elements 9, an annular circumferential stop 66 is provided which cooperates with a configured as an annular counter-stop 67 on the inner circumference of the water outlet 2 and the axial insertion movement the jet regulator housing 3 limited.

If the jet regulator 1 is to be released again from the water outlet 2 at the appropriate time, use is made of the unlocking tool 65. It is clear from a comparison of FIGS. 32 and 33 that this unlocking tool 65 can be introduced into the annular space 68 provided between the water outlet inner circumference and the outer circumference of the housing by means of an axial insertion movement. The axial insertion movement of the unlocking tool 65 m is a radial movement of the locking projections 10 m implemented the unlocked position as soon as the jet regulator housing 3 facing end edge of the sleeve-shaped unlocking tool 65 has reached the locking projections 10 supporting spring elements 9 and this Fe derelemente 9 now pushes inwards. The unlocking tool 65 is capable of enclosing the jet regulator housing 3 and the elastically molded spring elements 9 in such a way that the spring elements 9 with the latching projections 10 provided thereon are moved back within the enveloping circle defined by the largest housing diameter of the jet regulator housing 3 and the latching projections 10 with the jet regulator housing 3 disengaged.

In the detail illustration in FIG. 34, it can be seen that the jet regulator housing 3 and the unlocking tool 65 can be releasably latched to one another. At the jet regulator housing 3 a hook-shaped and annular circumferential projection 69 is provided for this purpose, which can engage behind a likewise annular circumferential projection 70 on the inner circumference of the sleeve-shaped unlocking tool 65. If the unlocking tool 65 and the jet regulator housing 3 are locked together, the spring elements 9 are also in their unlocked position, so that the jet regulator housing 3 together with the jet regulator 1 can be easily removed from the water outlet 2.

As can be seen from FIG. 35, the inflow-side subregion of the jet regulator housing 3 releasably latched with the unlocking tool 65 projects beyond the unlocking tool 65 in such a way that the jet regulator housing 3 is grasped at this projecting subarea and the catch connection is released with the unlocking tool 65 can.
