Die Neuerung betrifft eine Wasserablaufeinrichtung gemäß Oberbegriff des Anspruches 1.The innovation relates to a water drainage device according to the preamble of claim 1.

Eine solche Wasserablaufeinrichtung ist bereits durch DE-GM 81 07 539 bekannt geworden. Gegenstand dieses Gebrauchsmusters ist eine Tülle, die - wie sich in der praktischen Erprobung gezeigt hat - nicht die Aufgabenstellung erfüllt. Die Tülle soll nämlich zwei unterschiedliche Räume entwässern, und zwar einmal einen ersten Raum, z. B. eine Rinne des Schiebedaches, der über einen Wasserablaufschlauch mit der Tülle verbunden ist, und einen zweiten Raum, z. B. eine Karosserieblechmulde, der durch radial verlaufende Kanäle in den Abflußtrichter mündet. Es hat sich nun gezeigt, daß der sich in dem Wasserablaufschlauch aufbauende Staudruck im Abflußtrichter nicht ausreicht, den Haarspalt zu öffnen und das Wasser abfließen zu lassen. Dadurch dringt das angestaute Wasser durch die radialen Kanäle in den zweiten Raum ein. Anstatt nun diesen zweiten Raum zu entwässern, läuft dieser mit zusätzlichem Wasser aus dem ersten Raum voll. Die Neuerung soll diesen Mangel abstellen.Such a water drainage device has already become known through DE-GM 81 07 539. The subject of this utility model is a spout which - as practical testing has shown - does not fulfil the task. The spout is intended to drain two different spaces, namely a first space, e.g. a gutter of the sliding roof, which is connected to the spout via a water drainage hose, and a second space, e.g. a bodywork panel recess, which flows into the drainage funnel through radial channels. It has now been shown that the back pressure building up in the drainage funnel in the water drainage hose is not sufficient to open the hairline gap and allow the water to drain away. As a result, the accumulated water penetrates through the radial channels into the second space. Instead of draining this second space, it fills up with additional water from the first space. The innovation is intended to remedy this deficiency.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Anspruch 2 zeigt eine weitere Lösungsmöglichkeit zu der in den Ansprüchen 3 und 4 vorteilhafte Ausbildungen gezeigt sind. Näheres hierzu ist anschließend im Text erläutert und in der Zeichnung dargestellt. Im einzelnen zeigen:The problem is solved by the characterizing features of claim 1. Claim 2 shows a further possible solution, for which advantageous embodiments are shown in claims 3 and 4. Further details are explained in the text below and shown in the drawing. In detail:

In Figur 1 ist mit 1 das zu einer Mulde geformte Blech an der tiefsten Stelle eines Karosseriehohlraumes bezeichnet. Die allgemein mit 10 bezeichnete Wasserablauftülle besitzt eine umlaufende Ringnut 2, mit der sie von oben nach unten in das Karosserieblech 1 eingeknüpft ist. Die Ringnut 2 ist nach oben von einem sich innen gegen die Blechwand 1 abstützenden Ringkragen 3 und nach unten von einer sich außen an die Blechwand anlegenden umlaufenden Ringschulter 4 begrenzt. An die Ringschulter 4 sind zwei Lippen 5 angeformt, die einen Abflußtrichter 6 einschließen und in einen Haarspalt 7 münden, der einen einseitig wirkenden Lippenverschluß bildet. Einseitig deshalb, weil sich der Haarspalt 7 nur unter dem Druck des im Abflußtrichter angesammelten Wassers öffnet und dieses abfließen läßt, während er gegen von außen eindringendes Wasser einen zuverlässigen Verschluß bildet. An den Ringkragen ist ein rohrförmiger Anschlußstutzen 8 angeformt als Anschluß für einen Wasserablaufschlauch 9, der in axialer Richtung an einer innen an die Tülle angeformten Ringschulter 11 anstößt. Der Wasserablaufschlauch 9 kann beispielsweise entlang einer Karosseriewand zum SchiebedachIn Figure 1, 1 denotes the sheet metal formed into a trough at the deepest point of a body cavity. The water drain spout, generally designated 10, has a circumferential annular groove 2 with which it is tied into the body sheet metal 1 from top to bottom. The annular groove 2 is limited at the top by an annular collar 3 that rests against the inside of the sheet metal wall 1 and at the bottom by an annular shoulder 4 that rests against the outside of the sheet metal wall. Two lips 5 are formed on the annular shoulder 4, which enclose a drainage funnel 6 and open into a hairline gap 7 that forms a one-sided lip seal. One-sided because the hairline gap 7 only opens under the pressure of the water collected in the drainage funnel and allows it to drain away, while it forms a reliable seal against water penetrating from the outside. A tubular connection piece 8 is formed on the ring collar as a connection for a water drain hose 9, which abuts in the axial direction against an annular shoulder 11 formed on the inside of the grommet. The water drain hose 9 can, for example, be run along a body wall to the sunroof

geführt sein, um das dort in einer Rinne der Schiebedachöffnung sich sammelnde Regenwasser in die Tülle 10 und damit ins Freie abzuleiten. Der Ringkragen 3 ist von vier radial verlaufenden Kanälen 12 durchsetzt, die als Einlauf für am Boden 1· der Karosserieblechmulde sich sammelndes Wasser wirken. Auf diese Weise erfüllt die Wasserablauftülle eine doppelte Funktion: Das in der Mulde sich sammelnde Schwitzwasser wird durch die Kanäle 12 und das im Schiebedachbereich anfallende Wasser von außerhalb der Fahrzeugkarosserie über den Schlauch 9 in den Abflußtrichter 6 der Tülle und von dort ins Freie abgeleitet.in order to drain the rainwater collecting in a gutter of the sunroof opening into the spout 10 and thus into the open air. The ring collar 3 is penetrated by four radially running channels 12, which act as an inlet for water collecting on the floor 1 of the bodywork sheet metal recess. In this way, the water drain spout fulfills a dual function: the condensate collecting in the recess is drained through the channels 12 and the water accumulating in the sunroof area from outside the vehicle body via the hose 9 into the drain funnel 6 of the spout and from there into the open air.

Figur 4 zeigt eine Ausführung, bei der radial verlaufende Kanäle 12· bis an den Grund der Ringnut 2 herangeführt sind. Damit Wasser in diesem Bereich am Blech des Muldenbodens I1 abgeleitet werden kann, sind Ausnehmungen 13 vorgesehen. Kanäle 12' und Ausnehmungen 13 sollten vorteilhafter Weise zueinander fluchten, damit das Wasser ohne Umweg abfließen kann. Hierzu wird die Tülle 10 in der Mulde mittels Zentriereinrichtungen 15 in Ausbuchtungen 14 fixiert, wie dies insbesondere Figur 5 zeigt.Figure 4 shows a design in which radially extending channels 12' are led to the bottom of the annular groove 2. Recesses 13 are provided so that water can be drained off in this area on the sheet metal of the trough bottom 11. Channels 12' and recesses 13 should advantageously be aligned with one another so that the water can flow away without detours. For this purpose, the spout 10 is fixed in the trough by means of centering devices 15 in bulges 14, as shown in particular in Figure 5.
