An der in das Innere des Gehäuses 1 gerichteten Innenseite der Strahlscheibe 6 ist konzentrisch ein Ansatz 8 angeformt, der im wesentlichen zylindrisch ausgebildet ist. Der zylindrische Ansatz 8 greift in einen weiteren zylindrischen Ansatz 9 ohne Spiel ein, der im Inneren des Gehäuses 1 des Brausekopfs ausgebildet ist. Der dem Gehäuse 1 zugeordnete zylindrische Ansatz 9 erstreckt sich vom Becherboden 2 konzentrisch zu dessen Öffnung 3 und reicht bis etwa über die Hälfte der axialen Erstreckung des Gehäuses 1. An der Innenseite des zylindrischen Ansatzes 9 ist eine sich mindestens über einen Teil des Umfangs erstreckende keilförmige Nut 10 ausgebildet.Figure 1 shows an axial section through a shower head according to the invention. The shower head contains a housing 1 which has the shape of a cup. in the Cup bottom 2 has an opening 3 through which a connection element 4 round picks. The opposite side arranged at the bottom in FIG. 1 of the cup-like housing 1 forms an opening from the circumferential Edge 5 of the housing 1 is limited. The opening is through a Spray disc 6 covered, which is part of a spray disc element 7. At the in the inside of the housing 1 is the inside of the spray disc 6 A projection 8 is formed concentrically, which is essentially cylindrical is. The cylindrical neck 8 engages in another cylindrical neck 9 without A game that is formed inside the housing 1 of the shower head. The the housing 1 associated cylindrical extension 9 extends from Cup bottom 2 concentric with its opening 3 and extends up to about Half of the axial extent of the housing 1. On the inside of the cylindrical approach 9 is at least part of the circumference extending wedge-shaped groove 10 is formed.

Der zylindrische Ansatz 8 an der Innenseite der Strahlscheibe 6 weist über den Umfang verteilt mehrere in jeweils einer Durchgangsöffnung angeordnete federnde Schnappelemente 11 auf, die an ihrer Außenseite einen Rastvorsprung 12 enthalten. Der Rastvorsprung 12 greift in die umlaufende keilförmige Nut 10 ein, wenn das Strahlscheibenelement in das Ge-häuse 1 eingeschoben ist.The cylindrical extension 8 on the inside of the jet disc 6 has the Scope distributed several arranged in a through hole resilient snap elements 11, which have a locking projection on their outside 12 included. The locking projection 12 engages in the circumferential wedge-shaped groove 10 when the jet disc element is inserted into the housing 1.

Zur Abdichtung zwischen dem Rand der Strahlscheibe 6 und dem Rand 5 des Gehäuses 1 ist eine Dichtung 13 vorgesehen, die als Elastomerscheibe 14 ausgebildet ist und auf der Innenseite der Strahlscheibe 6 aufliegt. Die Dichtung 13 wird im Randbereich zwischen der Strahlscheibe 6 und dem Gehäuse 1 auf Kompression in axialer Richtung des Gehäuses beansprucht. Unter Axialrichtung ist die Richtung zwischen dem Boden 2 des Gehäuses und der Strahlaustrittsöffnung an der gegenüberliegenden Seite zu verstehen.To seal between the edge of the spray disc 6 and the edge 5 of the A housing 13 is provided with a seal 13, which acts as an elastomer disk 14 is formed and rests on the inside of the spray disc 6. The seal 13 is in the edge area between the spray disc 6 and the housing 1 Compression claimed in the axial direction of the housing. Under the axial direction is the direction between the bottom 2 of the housing and the Beam outlet opening to understand on the opposite side.

Die als Elastomerscheibe 14 ausgebildete Dichtung 13 ist an der Innenseite des zylindrischen Ansatzes 8 des Strahlscheibenelementes 7 bis zu dem freien Ende des zylindrischen Ansatzes 8 weitergeführt. Das Elastomermaterial greift durch radial verlaufende Öffnungen im Endbereich des Ansatzes 8 nach außen durch und dichtet das Gehäuse nach außen ab. An der Innenseite des zylindrischen Ansatzes 8 wird dadurch eine flächige Dichtung 15 gebildet, an der das Ende des An-schlusselements 4 flächig anlegt. Diese Dichtung 15 wird von dem zylindrischen Ansatz 8 des Strahlscheibenelements 7 unter Mitwirkung des zylindrischen Ansatzes 9 des Gehäuses 1 gegen den Endbereich des Anschlusselements 4 angedrückt.The seal 13 designed as an elastomer disc 14 is on the inside of the cylindrical approach 8 of the jet disc element 7 to the free end the cylindrical approach 8 continued. The elastomeric material takes hold radially extending openings in the end region of the extension 8 to the outside and seals the housing from the outside. On the inside of the cylindrical Approach 8 is thereby formed a flat seal 15 at which the end of the Connection element 4 is applied flat. This seal 15 is from the cylindrical approach 8 of the jet disc element 7 with the participation of cylindrical approach 9 of the housing 1 against the end portion of the Connection element 4 pressed.

Durch das unter Spannung erfolgende Anliegen der Dichtung 15 an der Außenseite des kugelartigen Endabschnitts 16 wird eine Bremsung erreicht, so dass das Gehäuse 1 in einer einmal eingenommenen Stellung arretiert wird. Das Gehäuse 1 kann jedoch gegenüber dem Endabschnitt 16 verschenkt werden. Der Endabschnitt 16 weist eine Durchgangsöffnung 17 für den Durchgang des Brausewassers auf. An seinem aus dem Gehäuse 1 herausragenden Abschnitt ist das Anschlusselement 4 so ausgebildet, dass es an einer Leitung oder einem Schlauch angeschraubt werden kann.In the example shown, the connection element 4 has an inside of the Housing 1 arranged spherical end portion 16. Through the under Tensioning concerns of the seal 15 on the outside of the spherical end section 16, braking is achieved, so that Housing 1 is locked in a position once taken. The housing 1 can, however, be given away with respect to the end section 16. The End section 16 has a through opening 17 for the passage of the Shower water on. On its section protruding from the housing 1 is the connecting element 4 formed so that it is on a line or a Hose can be screwed on.

Die die Dichtung 13 bildende Elastomerscheibe 14 ist auch durch Öffnungen der Strahlscheibe 6 hindurch gespritzt, wobei die durchgespritzten Teile die eigentlichen Strahlaustrittsöffnungen bilden.The elastomer disc 14 forming the seal 13 is also through openings in the Jet 6 injected through, the parts sprayed through the form actual beam outlet openings.

Die Brause wird folgendermaßen montiert. Zunächst wird das Anschlusselement 4 mit seinem in Figur 1 nach oben gerichteten Endabschnitt voraus in das Gehäuse 1 von dessen offener Seite aus eingeschoben, bis der kugelartigen Endabschnitt 16 am Rand der Durchgangsöffnungen 3 anlegt. Dann wird das Strahlscheibenelement von der offenen Seite des Gehäuses 1 in dieses eingeschoben, bis die Rastelemente 11 mit ihren Vorsprüngen 12 in die Nut 10 einschnappen. In diesem Zustand ist die Dichtung 13 im Randbereich komprimiert, so dass an dieser Stelle eine Abdichtung erfolgt. Auch am gegenüberliegenden Ende erfolgt eine Abdichtung durch den Dichtabschnitt 15. Toleranzen, die bei der Herstellung des Gehäuses und/oder des Strahlscheibenelements 7 auftreten können, werden durch die Verformung der Dichtung 13 im Randbereich überbrückt bzw. ausgeglichen. The shower is assembled as follows. First, the connector 4 with its end section pointing upwards in FIG. 1 into the Housing 1 inserted from its open side until the spherical End section 16 creates at the edge of the through openings 3. Then it will Jet disc element from the open side of the housing 1 in this inserted until the locking elements 11 with their projections 12 in the groove 10 snap. In this state, the seal 13 is in the edge area compressed so that there is a seal at this point. As well on opposite end is sealed by the sealing section 15. Tolerances in the manufacture of the housing and / or the Beam disc element 7 can occur due to the deformation of the Seal 13 bridged or balanced in the edge area.

Die Figur 2 zeigt eine leicht abgeänderte Ausführungsform. Die Verbindung zwischen dem Strahischeibenelement 7 und dem Gehäuse 1 geschieht in der gleichen Weise, nämlich durch Rastelemente 11, die an ihrer Außenseite im Endbereich Rastnasen 12 aufweisen. Die Federungen können auch an dem Gehäuse angeformt sein.Figure 2 shows a slightly modified embodiment. The connection between the jet disc element 7 and the housing 1 happens in the same way, namely by locking elements 11, which on the outside in End area have locking lugs 12. The suspensions can also be on the housing be molded on.

Zur Abdichtung des Gehäuses 1 gegenüber dem Anschlusselement 4 ist ein O-Ring 20 vorgesehen, der zwischen dem Becherboden 2, der Stimkante des zylindrischen Ansatzes 8 an der Innenseite des Strahlscheibenelements und dem zylindrischen Ansatz 9 an der Innenseite des Gehäuses 1 festgehalten wird. Der O-Ring 20 wird auch durch die freie Kante des zylindrischen Ansatzes 8 komprimierend beaufschlagt, so dass er in gleicher Weise eine Abdichtung als auch eine Abbremsung des Gehäuses 1 gegenüber dem Endabschnitt des Anschlusselementes 4 bewirkt.To seal the housing 1 with respect to the connection element 4 is a O-ring 20 provided between the cup bottom 2, the leading edge of the cylindrical approach 8 on the inside of the jet disc element and cylindrical approach 9 is held on the inside of the housing 1. The O-ring 20 is also through the free edge of the cylindrical projection 8th applied compressively, so that it is a seal in the same way also a braking of the housing 1 with respect to the end portion of the Connection element 4 causes.

Bei dieser Ausführungsform dient zur Abdichtung der Strahlscheibe 26 gegenüber dem Rand 5 des Gehäuses eine in einer radial offenen Nut angeordnete Dichtung 27. Zum Überbrücken von herstellungsbedingten Toleranzen ist das Strahischeibenelement 26 in einem Randbereich durch eine umlaufende Querschnittsverminderung 27 federnd ausgebildet. Daher liegt auch in diesem Fall die Strahfaustrittsscheibe 26 im Randbereich unter Spannung an dem Gehäuse 1 an.In this embodiment, the jet disc 26 is sealed opposite the edge 5 of the housing in a radially open groove arranged seal 27. For bridging manufacturing-related The radial disk element 26 is in an edge region due to tolerances circumferential reduction in cross section 27 resilient. Therefore lies too in this case, the beam exit disc 26 in the edge region under tension the housing 1.

Figur 3 zeigt eine weitere Ausführungsform, bei der die Strahlscheibe 36 ähnlich wie bei der Ausführungsform nach Figur 1 aus einem harten Teil aufgebaut ist, an dem eine Elastomerscheibe 14 angespritzt ist. Diese Elastomerscheibe 14 enthält wiederum durch Öffnungen der Strahlscheibe 36 durchgespritzte Teile, die die Strahlaustrittsöffnungen 18 bilden, Im Randbereich wird die Elastomerscheibe 14 zum Toleranzausgleich auf Kompression beansprucht. Zusätzlich ist an der in das Innere des Gehäuses 1 gerichteten Seite der Elastomerscheibe 14 im Randbereich eine Dichtlippe 31 angespritzt, die ebenfalls zum axialen Toleranzausgleich dient.FIG. 3 shows a further embodiment in which the jet disk 36 is similar as in the embodiment according to FIG. 1, is made up of a hard part, on which an elastomer disc 14 is molded. This elastomer disc 14 again contains parts sprayed through openings in the jet disc, which form the beam outlet openings 18, the Elastomeric disc 14 is used for tolerance compensation on compression. In addition, on the side facing the inside of the housing 1 Elastomer washer 14 molded in the edge area a sealing lip 31, the also used for axial tolerance compensation.

Der Dichtabschnitt 15, der zwischen dem zylindrischen Ansatz 8 des Strahlscheibenelements und dem Endabschnitt 16 des Anschlusselements 4 wirksam ist, ist über einen Anspritzkanal 32 mit der Elastomerscheibe 14 verbunden. Die axiale Festlegung geschieht wieder durch Rastelemente 11 mit Rastvorsprüngen 12.The sealing portion 15 which between the cylindrical extension 8 of the Spray disc element and the end section 16 of the connection element 4 is effective is via a gating channel 32 with the elastomer disc 14 connected. The axial fixing is done by locking elements 11 with Locking projections 12.

Figur 4 zeigt eine Ausführungsform, die der Ausführungsform nach Figur 3 ähnlich ist. Zur Verbindung zwischen dem Gehäuse 1 und der Strahlaustrittsscheibe 36 bzw. dem Strahlscheibenelement dient diesmal ein Bajonettverschluss, der im Endbereich des zylindrischen Ansatzes 8 des Strahlscheibenelements zwischen diesem und dem inneren des Gehäuses 1 wirksam ist. Im übrigen ist diese Ausführungsform ähnlich aufgebaut wie die Ausführungsform nach Figur 3, so dass sie nicht näher weiter beschrieben wird. Auch in diesem Fall gestaltet sich die Montage des Brausekopfs sehr einfach, da das Strahl- scheibenelement nur in den Ansatz 9 eingeschoben zu werden braucht, um anschließend verdreht zu werden, um den Bajonettverschluss zu schließen.FIG. 4 shows an embodiment that corresponds to the embodiment according to FIG. 3 is similar. For connection between the housing 1 and the Jet exit disk 36 or the jet disk element is used this time Bayonet lock, which in the end region of the cylindrical extension 8 of the Jet disc element between this and the interior of the housing 1st is effective. Otherwise, this embodiment is constructed similarly to that Embodiment according to Figure 3, so that it is not described in more detail. In this case, too, the installation of the shower head is very simple the jet disc element only to be inserted into the projection 9 needs to be turned afterwards to close the bayonet lock conclude.
