Description

Die Erfindung betrifft einen Multifunktionsbrausekopf mit einem Gehäuse, einer feststehenden Strahlplatte und einer verdrehbaren Strahlblende, in die eine Siebscheibe eingesetzt ist und mit der ein Verstellring festverbunden ist, wobei zwischen dem Gehäuse und der Strahlplatte eine Leitplatte mit Durchtrittskanälen und ein Laufrad mit radialen, ringförmig angeordneten Plättchen, Durchtrittsbereichen und Abdeckflächen vorgesehen ist.The invention relates to a multi-function shower head with a housing, a fixed radiant panel and a rotatable jet orifice, into which a screen disc is inserted and with which an adjustment ring is firmly connected, a guide plate with through-channels and an impeller with radial, ring-shaped arranged between the housing and the radiant panel Platelets, passage areas and cover surfaces is provided.

An Brausegarnituren hoher Qualität wird heutzutage u.a. die Anforderung gestellt, daß der Brausekopf auf verschiedene Strahlarten eingestellt werden kann. Dadurch kann man die Härte des Wasserstrahls und das Ausmaß der Luftbeimengung bestimmen und einen Massageeffekt erreichen.Today, high quality shower sets include the requirement that the shower head can be adjusted to different spray types. This allows you to determine the hardness of the water jet and the amount of air admixture and achieve a massage effect.

Bei den bisher kannten Brauseköpfen dieser Art wurden die verschiedenen Strahlarten durch mehrere Strahlplatten erzeugt, die gegeneinander verschoben wurden. Nachteilig dabei waren ein großes Volumen durch komplizierten Aufbau und eine unterschiedliche Strahlenanzahl bei den verschiendenen Funktionen. Insbesondere gilt dies für Brauseköpfe, bei denen auch ein Pulsationsbetrieb möglich ist. Ein solcher Brausekopf ist z.B. aus der US-A 5 090 624 bekannt. Bei dem Brausekopf gemäß dieser Druckschrift kann der Benutzer zwischen einem pulsierenden und einem nicht pulsierenden Wasserstrahl wählen. Für den Wasseraustritt sind zwei konzentrische Kreise mit Bohrungen vorgesehen, wobei der eine äußere für den nichtpulsierenden und der andere innere für den pulsierenden Betrieb dient. D.h. es sind den einzelnen Funktionen dabei verschiedene Regionen auf der Abschlußblende des Brausekopfes zugeordnet und es wird nie die gesamte Fläche dieser Abschlußblende genutzt.In the shower heads of this type known to date, the various types of spray were produced by means of several spray plates which were shifted against one another. A disadvantage here was a large volume due to the complicated structure and a different number of beams in the various functions. This applies in particular to shower heads in which pulsation operation is also possible. Such a shower head is known, for example, from US Pat. No. 5,090,624. In the shower head according to this document, the user can choose between a pulsating and a non-pulsating water jet. Two concentric circles with holes are provided for the water outlet, one outer for non-pulsating and the other inner for pulsating operation. Ie they are individual functions are assigned different regions on the end cover of the shower head and the entire surface of this end cover is never used.

Aufgabe der vorliegenden Erfindung ist es einen Brausekopf zu schaffen, der auf mehrere Strahlarten, insbesondere auch mit mindestens einer pulsierenden Strahlart, eingestellt werden kann und die oben genannten Nachteile nicht aufweist.The object of the present invention is to create a shower head which can be set to a plurality of spray types, in particular also with at least one pulsating spray type, and does not have the disadvantages mentioned above.

Die Aufgabe wird dadurch gelöst, daß zwischen der Siebscheibe (7) und der Strahlplatte (4) ein Anhebering (5) vorgesehen ist, der auf der einen Seite mit abgeschrägten Ansätzen (51) versehen ist, die auf einem ringförmigen, mit Stufen (81) versehenen Ansatz (82) an der Strahlblende (8) oder der Siebscheibe (7) gleiten, und der auf der anderen Seite mit Stiften (52) zur Blockierung des Laufrads (3) in angehobener Position des Anheberinges (5), d.h. wenn sich die abgeschrägten Ansätze (51) auf den Stufen (81) des ringförmigen Ansatzes (82) befinden, versehen ist.The object is achieved in that a lifting ring (5) is provided between the sieve disc (7) and the radiant panel (4), which is provided on one side with bevelled projections (51) which are arranged on an annular step (81 ) provided approach (82) on the jet diaphragm (8) or the screen disc (7), and on the other side with pins (52) for blocking the impeller (3) in the raised position of the lifting ring (5), ie when the bevelled lugs (51) are on the steps (81) of the annular lug (82) is provided.

Damit können mit dem Multifunktionsbrausekopf auch verschiedene Strahlenarten ohne Pulsation erzeugt werden. Durch Verdrehung der Strahlblende gegenüber dem Anhebering können die abgeschrägten Ansätze am Anhebering in abgesenkte Position, d.h. zwischen die Stufen gebracht werden und das Laufrad freigeben und damit einen pulsierenden Wasserstrahl zulassen oder in angehobene Position, d.h. auf die Stufen gebracht werden und das Laufrad blockieren und damit einen kontinuierlichen Wasserstrahl zulassen. Weiteres Verdrehen kann z.B. noch Luftbeimengung bewirken. Sowohl der pulsierende als auch der kontinuierliche Wasserstrahl ist über die gesamte Strahlblendenfläche verbreitet.This means that the multifunction shower head can also be used to generate different types of radiation without pulsation. By rotating the beam diaphragm in relation to the lifting ring, the bevelled lugs on the lifting ring can be in the lowered position, i.e. brought between the steps and release the impeller and thus allow a pulsating water jet or in a raised position, i.e. brought up to the steps and block the impeller and thus allow a continuous jet of water. Further twisting can e.g. still cause air admixture. Both the pulsating and the continuous water jet are spread over the entire jet aperture area.

Verlaufen die Durchtrittekanäle in der Leitplatte schräg zwischen Eintrittsöffnungen an der dem Gehäuse zugewandten Außenfläche und dazu in Umfangsrichtung versetzten Austrittsöffnungen an der dem Laufrad zugewandten Außenfläche, so weist die Strömungsrichtung der aus den Durchtrittskanälen tretenden Wasserstrahlen bereits eine zum Laufrad tangentiale Komponente auf und sichert damit deren Rotationsbeweguug.If the passage channels in the guide plate run obliquely between inlet openings on the outer surface facing the housing and outlet openings offset in the circumferential direction on the outer surface facing the impeller, then the direction of flow of the water jets emerging from the passage channels already has one Impeller tangential component and thus ensures their rotational movement.

Vorzugsweise durchsetzen die Stifte des Anheberings die Strahlplatte und liegen in angehobener Position des Anheberings am Laufrad an und heben es hoch, wobei auf der gegenüberliegenden Oberfläche des Laufrades ein Zahnkranz ausgebildet ist, der in einen an der Leitplatte vorgesehenen Zahnkranz eingreift. Der Abstand zwischen Laufrad und Strahlplatte wird in diesem Fall beim Anheben des Laufrades vergrößert und ein gleichmäßigeres Durchströmen der Stahlplatte auch in den unter den Abdeckflächen des Laufrades befindlichen Bereichen der Strahlplatte wird ermöglicht.The pins of the lifting ring preferably penetrate the radiant panel and lie in the raised position of the lifting ring on the impeller and lift it up, a toothed ring being formed on the opposite surface of the impeller, which meshes with a toothed ring provided on the guide plate. In this case, the distance between the impeller and the radiant panel is increased when the impeller is lifted, and a more even flow through the steel panel is also made possible in the areas of the radiant panel located under the cover surfaces of the impeller.

Der Anhebering weist erfindungsgemäß radiale, elastische Fortsätze auf, deren äußere Enden an der Strahlplatte anliegen und die in der angehobenen Position elastisch deformiert sind. Dadurch ist beim Zurückkehren in die abgesenkte Position des Anheberings, eine Rückstellkraft gegeben, die die Stifte zurückzieht und das Absenken und damit die Freigabe des Laufrades zuläßt.According to the invention, the lifting ring has radial, elastic extensions, the outer ends of which rest against the radiant panel and which are elastically deformed in the raised position. This gives a return force when returning to the lowered position of the lifting ring, which pulls the pins back and allows the lowering and thus the release of the impeller.

Zur Führung der Strahlplatte bei ihrer Drehung gegenüber der Strahlblende weist die Strahlplatte an ihrem Umfang einen Führungsansatz auf, der in einer Ausnehmung in der Strahlblende läuft, und einen elastisch befestigten Rastfortsatz, der in Kerben in der Strahlplatte einrastet, aufweist. Dies erleichtert die Bedienung des Brausekopfes und verhindert, daß ein unbeabsichtigtes Verstellen der gewählten Position erfolgt.For guiding the radiant panel as it rotates with respect to the radiant panel, the radiant panel has on its periphery a guide projection which runs in a recess in the radiant panel and an elastically fastened latching extension which engages in notches in the radiant panel. This simplifies the operation of the shower head and prevents unintentional adjustment of the selected position.

Zur Verdeutlichung der Erfindung wird nun der erfindungsgemäße Multifunktionsbrausekopf anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher beschrieben. Dabei zeigt die Fig.1 eine Explosionsansicht des Brausekopfes im Längsschnitt sowie rechts und links daneben die Draufsicht auf die wichtigsten Einzelteile. Die Fig.2 bis 4 zeigen den Brausekopf im Querschnitt in den verschiedenen Funktionsstellungen "Needle-Spray", "Soft-Spray" und "Pulsierender Massagestrahl".To clarify the invention, the multi-function shower head according to the invention will now be described in more detail with reference to an embodiment shown in the drawings. 1 shows an exploded view of the shower head in longitudinal section and to the right and left of it the top view of the most important individual parts. 2 to 4 show the shower head in cross section in the various functional positions "needle spray", "soft spray" and "pulsating massage jet".

Wie man in Fig.1 sieht enthält der Brausekopf eine Strahlblende 8 (im Schnitt und in einer Ansicht von oben dargestellt) mit einer Vielzahl von Strahldurchgängen 85, 86 unterschiedlicher Form. Um eine zentrale Bohrung 87 ist auf der dem Gehäuse 1 zugewandten Seite der Strahlblende 8 ein ringförmiger Ansatz 82 vorgesehen, der Stellen mit unterschiedlichen Höhen aufweist, wobei die Stellen mit größerer Höhe, nachfolgend als Stufen bezeichnet, mit dem Bezugzeichen 81 versehen wurden. Den ringförmigen Ansatz 82 umgehend ist eine Siebscheibe 7 in die Strahlenblende 8 eingesetzt, die an ihrem Umfang einen oder mehrere Stage 71 angeformt hat, die in Nuten 88 in der Strahlblend 8 eingreifen, um ein Verdrehen der Siebscheibe 7 gegenüber der Strahlblende 8 zu verhindern. Die Siebscheibe, 7 besteht aus einer Grundscheibe 72, die vorzugsweise beidseitig mit Sieben 73 bedeckt ist. Die Grundscheibe 72 weist Durchbrüche 74 auf, die mit einem Teil der Strahldurchgänge 85 in der Strahlblende 8 fluchten und denen entsprechende Ausschnitte 75 in den Sieben 73 zugeordnet sind. Andere Durchbrüche 76 in der Grundscheibe 72 hingegen sind mit den Sieben 73 bedeckt. Auf die Abstufung 89 der Strahlblende 8 wird ein Verstellring 6 aufgesetzt, wobei an die Strahlblende 8 angeformte Stege 89a in Nuten 61 des Verstellringes 6 eingreifen, um ein Verdrehen von Strahlblende 8 und Verstellring 6 gegeneinander zu verhindern.As can be seen in FIG. 1, the shower head contains a jet diaphragm 8 (shown in section and in a view from above) with a multiplicity of jet passages 85, 86 of different shapes. An annular extension 82 is provided around a central bore 87 on the side of the jet diaphragm 8 facing the housing 1, said attachment having locations with different heights, the locations with greater heights, hereinafter referred to as steps, being provided with the reference number 81. The ring-shaped extension 82 is immediately inserted into the screen 8, which has one or more stages 71 formed on its circumference, which engage in grooves 88 in the screen 8 to prevent the screen 7 from rotating relative to the screen 8. The screen disk 7 consists of a base disk 72, which is preferably covered on both sides with screens 73. The base plate 72 has openings 74 which are aligned with part of the beam passages 85 in the beam diaphragm 8 and to which corresponding cutouts 75 in the screens 73 are assigned. Other openings 76 in the base plate 72, however, are covered with the screens 73. An adjustment ring 6 is placed on the gradation 89 of the beam diaphragm 8, with webs 89a formed on the beam diaphragm 8 engaging in grooves 61 of the adjustment ring 6 in order to prevent the beam diaphragm 8 and the adjustment ring 6 from rotating relative to one another.

Weiters enthält der Brausekopf eine Strahlplatte 4 (im Schnitt und in einer Ansicht von unten dargestellt) mit Öffnungen 43, die je nach Winkelpositionierung der Strahlplatte 4 gegenüber der Strahlblende 8 mit eingesetzter Siebscheibe, 7 entweder den Strahlendurchgängen 85 und den Ausschnitten 75 (Needle-Spray-Stellung (Fig.2) u. Massagestellung Fig.4)) oder den mit Siebflächen bedeckten Strahlendurchgängen 86 (Soft-Spray-Stellung (Fig.3)) gegenüberliegen. In keiner Stellung wird eine der Öffnungen 43 durch die Strahlenblende 8 oder die Grundscheibe 72 der Siebscheibe 7 abgedeckt, sodaß die Anzahl der Strahlen in jeder Funktionsstellung gleich groß ist. Die Strahlplatte 4 weist an einer Stelle ihres Umfangs einen Führungsansatz 41 auf, der in einer Ausnehmung 83 in der Strahlblende 8 bei der Verdrehung derselben gegenüber der Strahlplatte 4 geführt wird.Furthermore, the shower head contains a radiant panel 4 (shown in section and in a view from below) with openings 43 which, depending on the angular positioning of the radiant panel 4 relative to the radiant panel 8 with the sieve disc inserted, 7 either the jet passages 85 and the cutouts 75 (needle spray Position (Fig. 2) and massage position Fig. 4)) or the beam passages 86 covered with screen surfaces (soft spray position (Fig. 3)). In no position is one of the openings 43 covered by the radiation diaphragm 8 or the base plate 72 of the sieve plate 7, so that the number of beams is the same in each functional position. The radiant panel 4 has a guide projection 41 at one point on its circumference, which is guided in a recess 83 in the radiant panel 8 when the latter is rotated relative to the radiant panel 4.

An den beiden Enden und in der Mitte der Ausnehmung 83 sind Kerben 84 in der Strahlblende 8 vorgesehen, in die ein Rastfortsatz 42 der Strahlplatte 4 einrastet, um die der gewählten Funktion entsprechende Position zu halten. Auf der von der Strahlblende 8 abgewandten Seite der Strahlplatte 4 ist ein Laufrad 3 in die Strahlplatte 4 eingesetzt. Dieses Laufrad 3 (in Schnitt und in einer Ansicht von oben dargestellt) läuft um eine ringförmige Erhöhung 44 der Strahlplatte und enthält radiale, ringförmig angeordnete Plättchen 31, Durchtrittsbereiche 32 und Abdeckflächen 33. Das auf die Plättchen 31 auftreffende Wasser setzt das Laufrad 3 in Rotation, bei der die Abdeckflächen 33 in rasche Folge die Öffnungen 43 der Strahlplatte 4 verdecken und wieder freigeben. Eine oberhalb des Laufrades 3 vorgesehene Leitplatte 2 hat Durchtrittskanäle 21, deren Eintrittsöffnungen 22 und Austrittsöffnungen 23 jeweils in Umfangsrichtung gegeneinander versetzt sind. Das durch diese Kanäle 21 strömende Wasser trifft somit schräg auf die radialen Plättchen 31 und sichert die Rotation des Laufrades 3.At both ends and in the middle of the recess 83, notches 84 are provided in the beam aperture 8, into which a latching extension 42 of the beam plate 4 snaps in order to hold the position corresponding to the selected function. On the side of the radiant panel 4 facing away from the jet diaphragm 8, an impeller 3 is inserted into the radiant panel 4. This impeller 3 (shown in section and in a view from above) runs around an annular elevation 44 of the radiant panel and contains radial, annularly arranged plates 31, passage areas 32 and cover surfaces 33. The water impinging on the plates 31 sets the impeller 3 in rotation , in which the cover surfaces 33 quickly cover and uncover the openings 43 of the radiant panel 4. A guide plate 2 provided above the impeller 3 has passage channels 21, the inlet openings 22 and outlet openings 23 of which are each offset in the circumferential direction. The water flowing through these channels 21 thus strikes the radial plates 31 at an angle and ensures the rotation of the impeller 3.

Zwischen Siebscheibe 7 bzw. Strahlblende 8 und Strahlplatte 4 ist ein Anhebering 5 eingesetzt, der auf seiner der Strahlblende 8 zugewandten Seite zwei abgeschrägte Ansätze 51 aufweist, welche auf dem ringförmigen Ansatz 82 der Strahlblende 8 laufen. Auf seiner anderen Seite weist der Anhebering 5 vier Stifte 52 auf, die die Strahlplatte 4 durchsetzen. Weiters sind am Anhebering 5 vier radiale, elastische Fortsätze 53 vorgesehen, deren Faden sich an der Strahlplatte 4 abstützen. Je nach Stellung der Strahlblende 8 gegenüber dem Anhebering 5 befinden sich dessen Ansätze 51 auf den Stufen 81 des ringförmigen Ansatzes 82 und der Anhebering 5 ist in gehobener Position oder die Ansätze 51 befinden sich zwischen den Stufen 81 und der Anhebering 5 ist in abgesenkter Position. In angehobener Position wird der Anhebering 5 unter elastischer Deformierung seiner Fortsätze 53 gegen die Strahlplatte 4 gedrückt und die Stifte 52 ragen auf der dem Laufrad 3 zugewandten Seite aus der Strahlplatte 4 hervor, liegen am Laufrad 3 an und haben es hoch. Das Laufrad 3 hat an seiner der Leitplatte 2 zugewandten Seite einen Zahnkranz 34 der beim Anheben in einen Zahnkranz 24 an der Leitplatte 2 eingreift. Damit ist die Rotation des Laufrades 3 blockiert. Durch da Heben des Laufrades 3 wird auch der Abstand zwischen Laufrad 3 und Strahlplatte 4 vergrößert, sodaß alle Öffnungen 43 der Strahlplatte 4, auch die durch die Abdeckflächen 33 des Laufrades 3 verdeckten, gleichmäßig durchströmt werden. Durch Drehen der Strahlblende 8 kann man den Anhebering 5 wieder in die abgesenkte Position bringen, wobei die elastischen Fortsätze 53 die nötige Rückstellwirkung erzeugen um die Stifte 52 zurückzuziehen und die abgeschrägten Ansätze 51 des Anheberings 5 in die Bereiche zwischen den Stufen 81 am ringförmigen Ansatz 82 zu drücken. Eine Schraube 9 durchsetzt die Strahlblende 8, den Anhebering 5, die Strahlplatte 4 und das Laufrad 3 und greift in ein Gewinde in der Leitplatte 2 ein. Der so zusammengefügte Einsatz wird im Gehäuse festgelegt. Mehrere O-Ringe 11 dienen zur Abdichtung des Brausekopfes.A lifting ring 5 is inserted between the screen disk 7 or the jet orifice 8 and the jet plate 4 and has two bevelled projections 51 on its side facing the jet orifice 8, which run on the annular attachment 82 of the jet orifice 8. On its other side, the lifting ring 5 has four pins 52 which penetrate the radiant panel 4. Furthermore, four radial, elastic extensions 53 are provided on the lifting ring 5, the threads of which are supported on the radiant panel 4. Depending on the position of the jet diaphragm 8 with respect to the lifting ring 5, its projections 51 are located on the steps 81 of the annular projection 82 and the lifting ring 5 is in the raised position or the projections 51 are located between the steps 81 and the lifting ring 5 is in the lowered position. In the raised position, the lifting ring 5 is pressed against the radiant panel 4 with elastic deformation of its extensions 53, and the pins 52 protrude from the radiant panel 4 on the side facing the impeller 3, lie against the impeller 3 and have it high. The impeller 3 has on its side facing the guide plate 2 a ring gear 34 which engages in a ring gear 24 on the guide plate 2 when it is raised. So that is the rotation of the impeller 3 is blocked. By lifting the impeller 3, the distance between the impeller 3 and the radiant panel 4 is also increased, so that all openings 43 of the radiant panel 4, even those covered by the cover surfaces 33 of the impeller 3, are evenly flowed through. By turning the jet diaphragm 8, the lifting ring 5 can be brought back into the lowered position, the elastic extensions 53 producing the necessary restoring action to pull back the pins 52 and the beveled extensions 51 of the lifting ring 5 into the areas between the steps 81 on the annular extension 82 to press. A screw 9 passes through the jet diaphragm 8, the lifting ring 5, the jet plate 4 and the impeller 3 and engages in a thread in the guide plate 2. The insert assembled in this way is defined in the housing. Several O-rings 11 serve to seal the shower head.

Die Fig.2 zeigt den Brausekopf in der Needle-Spray-Stellung. Die Strahlplatte 4 steht gegenüber der Strahlblende 8 und der Siebscheibe 7 so, daß die durch die Öffnungen 43 austretende Wasserstrahlen durch die Ausschnitte 75 in den Sieben 73, die Durchbrüche 74 der Grundscheibe 72 und die Strahldurchgänge 85 in der Strahlblende 8 strömen. Die abgeschrägten Ansätze 51 des Anheberings 5 befinden sich auf den Stufen 81 des ringförmigen Ansatzes 82 der Strahlblende 8, d.h. der Anhebering nimmt die angehobene Position ein, und die Stifte 52 des Anheberings 5 liegen am Laufrad 3 an und heben es hoch. Der Zahnkranz 34 des Laufrades 3 greift in den Zahnkranz 24 der Leitplatte 2, wodurch das Laufrad 3 blockiert ist. Der erzeugte Wasserstrahl ist nicht pulsierend.Fig. 2 shows the shower head in the needle spray position. The jet plate 4 is opposite the jet diaphragm 8 and the sieve disc 7 so that the water jets emerging through the openings 43 flow through the cutouts 75 in the sieves 73, the openings 74 of the base plate 72 and the jet passages 85 in the jet diaphragm 8. The beveled lugs 51 of the lifting ring 5 are located on the steps 81 of the annular lug 82 of the beam diaphragm 8, i.e. the lifting ring assumes the raised position, and the pins 52 of the lifting ring 5 rest against the impeller 3 and lift it up. The ring gear 34 of the impeller 3 engages in the ring gear 24 of the guide plate 2, whereby the impeller 3 is blocked. The water jet generated is not pulsating.

Die Fig.3 zeigt den Brausekopf in der Soft-Spray-Stellung. Die Strahlplatte 4 steht gegenüber der Strahlblende 8 und der Siebscheibe 7 so, daß die durch die Öffnungen 43 austretenden Wasserstrahlen durch die Durchbrüche 76 der Grundscheibe 72, die durch die Siehe 73 bedeckt sind, und die Strahldurchgänge 86 in der Strahlblende 8 strömen. Die abgeschrägten Ansätze 51 des Anheberings 5 befinden sich auch in dieser Stellung auf den Stufen 81 des ringförmigen Ansatzes 82 der Strahlblende 8, d.h. der Anhebering nimmt die angehobene Position ein, und die Stifte 52 des Anheberings 5 liegen am Laufrad 3 an und heben es hoch. Der Zahnkranz 34 des Laufrades 3 greift in den Zahnkranz 24 der Leitplatte 2 ein, wodurch das Laufrad 3 blockiert ist. Der erzeugte Wasserstrahl ist nicht pulsierend und mit Luft vermengt.3 shows the shower head in the soft spray position. The jet plate 4 is opposite the jet orifice 8 and the sieve plate 7 such that the water jets emerging through the openings 43 flow through the openings 76 in the base plate 72, which are covered by the see 73, and the jet passages 86 in the jet orifice 8. The beveled lugs 51 of the lifting ring 5 are also in this position on the steps 81 of the annular extension 82 of the beam diaphragm 8, ie the lifting ring takes the raised one Position, and the pins 52 of the lifting ring 5 lie on the impeller 3 and lift it up. The ring gear 34 of the impeller 3 engages in the ring gear 24 of the guide plate 2, whereby the impeller 3 is blocked. The water jet generated is not pulsating and mixed with air.

Die Fig.4 zeigt den Brausekopf in der Stellung mit pulsierendem Massagestrahl. Die Strahlplatte 4 steht gegenüber der Strahlblende 8 und der Siebscheibe 7 so, daß die durch die Öffnungen 43 austretenden Wasserstrahlen durch die Ausschnitte 75 in den Sieben 73, die Durchbrüche 74 der Grundscheibe 72 und die Strahldurchgänge 85 in der Strahlblende 8 strömen. Die abgeschrägten Ansätze 51 des Anheberings 5 befinden sich zwischen den Stufen 81 des ringförmigen Ansatzes 82 der Strahlblende 8, d.h. der Anhebering nimmt die abgesenkte Position ein, und die Stifte 52 des Anheberings 5 liegen in der Strahlplatte 4. Zwischen Laufrad 3 und den Stiften 52 ist ein Abstand zu erkennen und das Laufrad 3 liegt tiefer als in den Fig.2 und 3, sodaß der Zahnkranz 34 des Laufrades 3 nicht in den Zahnkranz 24 der Leitplatte 2 eingreift und eine freie Drehung des Laufrades 3 möglich ist. Der erzeugte Wasserstrahl ist pulsierend.4 shows the shower head in the position with a pulsating massage jet. The jet plate 4 is opposite the jet diaphragm 8 and the sieve disc 7 so that the water jets emerging through the openings 43 flow through the cutouts 75 in the sieves 73, the openings 74 of the base plate 72 and the jet passages 85 in the jet diaphragm 8. The beveled lugs 51 of the lifting ring 5 are located between the steps 81 of the annular lug 82 of the beam diaphragm 8, i.e. the lifting ring assumes the lowered position, and the pins 52 of the lifting ring 5 lie in the radiant panel 4. A distance can be seen between the impeller 3 and the pins 52 and the impeller 3 is lower than in FIGS. 2 and 3, so that the Sprocket 34 of the impeller 3 does not engage in the sprocket 24 of the guide plate 2 and free rotation of the impeller 3 is possible. The water jet generated is pulsating.
