Description
Die Erfindung betrifft einen Zentrierdichtring für eine Sanitärarmatur, insbesondere eine Waschtischarmatur, mit einem einen größeren Durchmesser aufweisenden ringflanschartigen Bereich, der zur Anordnung zwischen der unteren Seite der Sanitärarmatur und der Oberseite eines Waschtisches oder dergleichen ausgebildet ist, und mindestens einem daran einstückig angeformten, einen kleineren Durchmesser aufweisenden und sich nach unten erstreckenden Zentrierbereich, der zum Einführen in das Hahnloch des Waschtisches oder dergleichen ausgebildet ist.The invention relates to a Zentrierdichtring for a sanitary fitting, in particular a washbasin faucet, with a larger diameter annular flange-like area, which is designed to be arranged between the lower side of the sanitary fitting and the top of a washstand or the like, and at least one integrally formed thereon, a smaller Diameter-having and downwardly extending centering, which is designed for insertion into the tap hole of the washbasin or the like.
Wenn vorliegend von "Waschtisch oder dergleichen" gesprochen wird, so ist hiermit sowohl ein Waschbecken mit breitem Rand als auch diejenige Ausgestaltung gemeint, bei welcher an einer Platte ein Aufsatzbecken befestigt ist.If "washbasin or the like" is used in this case, this means both a wide-rimed washbasin and that design in which a topped basin is attached to a plate.
Wenn Sanitärarmaturen auf einem Waschtisch montiert werden sollen, muss auf zweierlei geachtet werden: Zum einen ist eine zuverlässige Abdichtung zwischen der Unterseite der Sanitärarmatur und der Oberseite des Waschtisches erforderlich. Zum anderen muss die Sanitärarmatur gegenüber dem Hahnloch des Waschtisches zumindest so gut zentriert werden, dass die zwischen der Unterseite der Sanitärarmatur und der Oberseite des Waschtisches einliegende Dichtung an keiner Stelle freiliegt, also statt auf der Oberseite des Waschtisches aufzuliegen bereichsweise frei über dem Hahnloch des Waschtisches verläuft.If sanitary fittings are to be mounted on a washbasin, two things have to be taken into consideration: First, a reliable seal between the underside of the sanitary fitting and the top of the washbasin is required. On the other hand, the sanitary fitting relative to the tap hole of the washstand must be at least so well centered that the inset between the bottom of the sanitary fitting and the top of the washstand uncovered at any point, so instead of resting on the top of the washstand partially free above the tap hole of the washstand runs.
Beide Aufgaben übernehmen sog. Zentrierdichtringe der eingangs genannten Art, wie sie beispielsweise aus der
Aufgabe der vorliegenden Erfindung ist es, einen Zentrierdichtring der eingangs genannten Art so auszugestalten, dass sich auch bei unterschiedlichen Durchmessern des Hahnloches sowohl eine gute Abdicht- als auch eine gute Zentrierwirkung einstellt.
Diese Aufgabe wird neben den oberbegriffsbildenden Merkmalen erfindungsgemäß dadurch gelöst, dass
- b) an die Unterseite des ringflanschartigen Bereichs eine Formdichtung im Zwei-Komponenten-Spritzverfahren angeformt ist, die eine zweite Härte aufweist, die kleiner als die erste Härte ist.
This object is achieved according to the invention in addition to the generic term features that
- b) is integrally formed on the underside of the annular flange portion a molded seal in the two-component injection molding method, which has a second hardness, which is smaller than the first hardness.
Erfindungsgemäß werden also die beiden Funktionen, die einem Zentrierdichtring zukommen, zwei Bereichen des Zentrierdichtringes zugewiesen, die einerseits unterschiedliche Härte aufweisen, aber andererseits doch durch ein Zweikomponenten-Spritzverfahren einstückig miteinander verbunden sind. Die größere Härte insbesondere des Zentrierbereiches stellt sicher, dass der mit diesem Zentrierbereich in das Hahnloch eingeschobene Zentrierdichtring sich nicht mit geringer Kraft in seitlicher Richtung verschieben lässt, wodurch die Zentrierwirkung verloren gehen würde. Die geringere Härte der Formdichtung dagegen stellt eine zuverlässige Dichtwirkung sicher, da mit geringer Kraft eine ausreichende Verformung dieses Bereiches beim Aufsetzen der Sanitärarmatur auf den Waschtisch möglich ist, ohne dass zwischen der Unterseite der Waschtischarmatur und der Oberseite des Waschtisches ein Spalt verbleibt.According to the invention, therefore, the two functions that are attributable to a centering, assigned to two areas of Zentrierdichtringes, on the one hand have different hardness, but on the other hand, but are integrally connected by a two-component injection molding process. The greater hardness in particular of the centering ensures that the inserted with this centering in the tap hole Centering seal can not be moved with little force in the lateral direction, whereby the centering effect would be lost. The lower hardness of the molded seal, however, ensures a reliable sealing effect, since with little force sufficient deformation of this area when placing the sanitary fitting on the vanity is possible without leaving a gap between the bottom of the basin mixer and the top of the vanity.
Zweckmäßigerweise beträgt die erste Härte des ringflanschartigen Bereichs und des Zentrierbereichs etwa 170 HB (Brinell-Härte), während die zweite Härte der Formdichtung etwa 50 bis 70 HB (etwa Shore-Härte A) beträgt.Conveniently, the first hardness of the annular flange portion and the centering portion is about 170 HB (Brinell hardness), while the second hardness of the molded seal is about 50 to 70 HB (about Shore hardness A).
Besonders geeignet ist ein Zentrierdichtring, der aus aus thermoplastischem Polymer auf der Basis von Polybutylen terephthalat (härtere Komponente) bzw. Poly(organo)siloxan (weichere Komponente) gefertigt ist.Particularly suitable is a Zentrierdichtring which is made of thermoplastic polymer based on polybutylene terephthalate (harder component) or poly (organo) siloxane (softer component).
Der Zentrierbereich kann mehrere in Umfangsrichtung voneinander beabstandete Zentriersegmente umfassen. Dies erleichtert gegenüber einer Ausgestaltung, die einem vollständigen Ring entspricht, das radiale Einwärtsbiegen des Zentrierbereiches in Hahnlöcher, deren Durchmesser kleiner als der Durchmesser des unverformten Zentrierbereiches ist.The centering region may comprise a plurality of circumferentially spaced centering segments. This facilitates compared to a configuration which corresponds to a complete ring, the radial inward bending of the centering area in tap holes whose diameter is smaller than the diameter of the undeformed centering.
Bei einer vorteilhaften Ausführungsform der Erfindung ist an den ringflanschartigen Bereich eine Klemmdurchführung für den Stehbolzen der Sanitärarmatur angeformt. Diese Klemmdurchführung dient dazu, den Zentrierdichtring schon vor dem Aufsetzen der Sanitärarmatur auf den Waschtisch an der Sanitärarmatur festzulegen, indem sie auf den Stehbolzen der Sanitärarmatur aufgeschoben wird und dort mit einem gewissen Reibschluss haftet. Dieser Stehbolzen dient bekanntlich der Montage der Sanitärarmatur an dem Waschtisch.In an advantageous embodiment of the invention, a clamping bushing for the stud of the sanitary fitting is integrally formed on the ring flange-like area. This clamping bushing is used to set the centering ring before the sanitary fitting on the washstand to the sanitary fitting, by being pushed onto the stud of the sanitary fitting and adhering there with a certain frictional engagement. This stud is known to be used for mounting the sanitary fitting to the vanity.
Die Formdichtung ist vorteilhafterweise nach außen durch eine Zylindermantelfläche begrenzt. So kann die Formdichtung auf einer Linie dichten, die, verglichen mit einer O-Ringdichtung, radial weiter außen liegt; auf diese Weise lässt sich der erfindungsgemäße Zentrierdichtring bei größeren Hahnlöchern einsetzen, als dies bei Verwendung von O-Ringdichtungen möglich wäre.The molded seal is advantageously limited to the outside by a cylinder jacket surface. Thus, the molded gasket can seal on a line that is radially outward compared to an O-ring gasket; In this way, the Zentrierdichtring invention can be used with larger tap holes, as would be possible with the use of O-ring seals.
Zweckmäßig ist ferner, wenn sich die Formdichtung nach unten verjüngt, wodurch sich in demjenigen unteren Bereich der Formdichtung, die in unverformtem Zustand über die Unterseite der Sanitärarmatur nach unten ragt, eine Art Dichtlippe ergibt. Auf diese Weise ist die Kraft, die zur Verformung dieses überstehenden Bereiches erforderlich ist, um eine gute Dichtwirkung zu erzielen, vergleichsweise klein und es ist gewährleistet, dass die Unterseite der Sanitärarmatur spaltfrei auf der Oberseite des Waschtisches nach Abschluss der Montage aufliegt.It is also expedient if the molded gasket tapers downwards, resulting in a type of sealing lip in that lower region of the molded gasket, which protrudes downwards in undeformed state over the underside of the sanitary fitting. In this way, the force required to deform this projecting portion to achieve a good sealing effect is comparatively small and it is ensured that the underside of the sanitary fitting rests gap-free on the top of the washstand after completion of assembly.

Zunächst wird auf die
Der aus einem härteren Material gefertigte Teil 2 des Zentrierdichtringes 1 umfasst einen ringflanschartigen Bereich 2a, der sich in radialer Richtung bis zum größten Durchmesser des Zentrierdichtringes 1 erstreckt. Der Rand dieses ringflanschartigen Bereichs 2a trägt mehrere radial vorspringende Klemmnoppen 13. An den ringflanschartigen Bereich 2a ist ausserdem ein Zentrierbereich 2b in Form von mehreren nach unten ragenden Zentriersegmenten 2bb angeformt, welche die Gestalt von Ausschnitten einer Hohlzylinderwand besitzen. Im dargestellten Ausführungsbeispiel sind drei derartige Zentriersegmente 2bb in einem Winkelabstand in Umfangsrichtung von 120° vorgesehen.The made of a
Ebenfalls einstückig angeformt an die Unterseite des ringflanschartigen Bereichs 2a, radial weiter innenliegend, ist eine Klemmdurchführung 2c, welche in nachfolgend noch zu beschreibender Weise der Festlegung des Zentrierdichtringes 1 an dem Stehbolzen dient, mit welchem die Waschtischarmatur an dem Waschtisch befestigt wird. Die Klemmdurchführung 2c hat die Form einen Hohlzylinders, von dem im radial außen liegenden Bereich ein Teil abgeschnitten ist, so dass im Querschnitt annähernd die Form eines U entsteht. Der Radius der Durchgangsbohrung durch die Klemmdurchführung 2c entspricht im Wesentlichen dem Radius des Stehbolzens der Waschtischarmatur.Also integrally formed on the underside of the annular flange portion 2a, radially further inboard, is a clamping bushing 2c, which serves in the manner to be described below the determination of the Zentrierdichtringes 1 on the stud, with which the washstand fitting attached to the washstand. The clamping
An die Unterseite des ringflanschartigen Bereichs 2a ist eine aus weicherem Material bestehende Formdichtung 3 angespritzt. Um die Verbindung zwischen der Formdichtung 3 und dem Flansch 2a zu verbessern, besitzt der ringflanschartige Bereich 2a über den Umfang verteilt mehrere Durchgangsbohrungen 4, in welche das Material der Formdichtung 3 beim Anspritzvorgang eindringen kann. Die Formdichtung 3 hat eine zylindrische Außenwand, deren Radius mit dem Außenradius des ringflanschartigen Bereichs 2a (ohne Berücksichtigung der Klemmnoppen 13) übereinstimmt. Sie verjüngt sich von oben nach unten, wobei jedoch der Außenradius unverändert bleibt. Dies ist insbesondere der
Wie der oben beschriebene Zentrierdichtring 1 an einer Waschtischarmatur eingesetzt wird, ist den nachfolgend beschriebenen
Beim Einsetzen des Zentrierdichtringes 1 in den Rücksprung 6 der Waschtischarmatur 5 wird die Klemmdurchführung 2c über den Stehbolzen 7 geführt, der im Bodenbereich der Waschtischarmatur 5 in bekannter Weise befestigt ist und in ebenso bekannter Weise der Montage der Waschtischarmatur 5 an einem Waschtisch 8 dient.When inserting the Zentrierdichtringes 1 in the recess 6 of the washstand fitting 5, the
Nur der Vollständigkeit halber sei noch erwähnt, dass in den
Beim Aufschieben des Zentrierdichtringes 1 über dem Stehbolzen 7 stellt sich ein leichter Reibschluss zwischen der Klemmdurchführung 2c und dem Stehbolzen 7 ein, so dass der Zentrierdichtring 1 nach dem Platzieren in dem Rücksprung 6 der Waschtischarmatur 5 dort vormontiert verbleibt und nicht mehr verloren geht.When pushing the Zentrierdichtringes 1 on the stud bolt 7, a slight frictional engagement between the clamping
Wird dann die Waschtischarmatur 5 mit dem eingesetzten Zentrierdichtring 1 auf dem Waschtisch 8 aufgesetzt und gegen diesen so verspannt, dass die ringförmige Aufstandsfläche 11 der Waschtischarmatur 5 an der Oberseite des Waschtisches 8 anliegt, so verformt sich die Formdichtung 3 des Zentrierdichtringes 1 in der zur Herstellung einer zuverlässigen Abdichtung zwischen Waschtischarmatur 5 und Waschtisch 8 erforderlichen Weise. Gleichzeitig sorgen die Zentriersegemente 2bb des Zentrierdichtringes 1 für eine Zentrierung der Waschtischarmatur 5 innerhalb des Hahnloches 12 des Waschtisches, wobei bei kleineren Durchmessern des Hahnloches 12 ein gewisse radiale Verbiegung der Zentriersegmente 2bb nach innen erfolgt. Auf diese Weise ist eine zuverlässige Zentrierung der Waschtischarmatur 5 auf dem Hanhloch 12 des Waschtisches in einem ganzen Durchmesserbereich des Hahnloches 12 möglich, wobei stets eine zuverlässige Abdichtung zwischen der Aufstandsfläche 11 der Waschtischarmatur 5 und der Oberseite des Waschtisches 8 gewährleistet ist.If then the washbasin fitting 5 is placed with the Zentrierdichtring 1 on the washstand 8 and clamped against this so that the
