Abstract

The waterproof seal has a foam strip (3) impregnated with adhesive applied as a bonding layer between overlapping edges of adjoining car body panels (1,2), with bolts providing additional security. The outer surfaces of the foam are heat treated to become non-porous. The heat treatment occurs in the baking process for the paintwork and forms a durable seal. The metal surface adjacent to the foam is pretreated with corrosion inhibitor or a bitumen. The foam provides a simple seal with the body panels removable when damaged.(DS).

Patentanspruch:Claim: Abdichtung von lösbar oder unlösbar miteinander zu verbindenden, aus Blech bestehenden Teilen, insbesondere von Wagenkasten von Kraftfahrzeugen, mittels zwischen diesen Teilen angeordneter, mit einem Kleber getränkter Schaumstoffeinlagen, dadurch gekennzeichnet, daß die Schaumstoffeinlagen als über die ganze Länge der Verbindung durchgehende Schaumstoffstreifen (3) ausgebildet und ihre nach dem Zusammenbau der Teile freien Flächen durch Randleisten (-}) abgedeckt sind, die bei den in Lacktrockenöfen üblichen Temperaturen schmelzen und/oder aushärten und so eine Abdichtung der Schaumstoffstreifen (3) gegen Feuchtigkeit usw. bewirken.Sealing of parts made of sheet metal that can be detachably or permanently connected to one another, in particular of car bodies of motor vehicles, by means of arranged between these parts, Foam inserts impregnated with an adhesive, characterized in that the foam inserts designed as continuous foam strips (3) over the entire length of the connection and their after assembly of the Parts of free areas are covered by edge strips (-}), which are common in paint drying ovens Temperatures melt and / or harden and thus seal the foam strips (3) against Cause moisture, etc. Die Erfindung betrifft eine Abdichtung von lösbar oder unlösbar miteinander zu verbindenden, aus Blech bestehenden Teilen, insbesondere Teilen von Wagenkasten von Kraftfahrzeugen, mittels zwischen diesen Teilen angeordneter, mit einem Kleber getränkter Schaumstoffeinlagen.The invention relates to a seal made of sheet metal that is to be detachably or permanently connected to one another existing parts, in particular parts of car bodies of motor vehicles, by means of between them Parts of arranged foam inserts soaked with an adhesive. Es ist bekannt, mit Klebstoff getränkte Dichtscheiben aus Schaumstoff zum Abdichten von lösbaren Schrauboder Klemmverbindungen zu verwenden. Diese können zwar an der Verbindungsstelle ein die Blechteile gefährdendes Eindringen von Feuchtigkeit verhindern, die dazwischen liegenden Abschnitte sind aber ungeschützt. Das gleiche trifft für Falz-, Klemm- oder Nietverbindungen von Blechieilen zu, bei denen die Blechteile nicht durchgehend dicht aneinander liegen. Auch bei Schweiß-, Lot- oder dauerhaften Klebverbindungen kann die Verbindungsnaht an einzelnen Stellen oder an den Rändern unterbrochen oder nicht vorhanden sein. Selbst im Fall einwandfreier bleibender Verbindung kann die mit der Luft eingeschlossene Feuchtigkeit an den Blechteilen eine korrodierende Wirkung ausüben.It is known, with adhesive impregnated foam sealing disks for sealing detachable screw or To use clamp connections. These can indeed be the sheet metal parts at the connection point Prevent dangerous penetration of moisture, but the sections in between are unprotected. The same applies to folded, clamped or riveted connections of sheet metal parts, where the Sheet metal parts are not continuously close to one another. Even with welded, soldered or permanent adhesive connections the seam may or may not be interrupted at individual points or at the edges to be available. Even in the case of a perfect permanent connection, the trapped with the air can Moisture can have a corrosive effect on the sheet metal parts. Demgegenüber liegt der Erfindung die Aufgabe zugrunde, die Abdichtung gemäß der eingangs genannten Gattung so zu verbessern, daß eine korrosionssichere Verbindung von Blechteilen ermöglicht wird.In contrast, the invention is based on the object of the seal according to the aforementioned To improve the species so that a corrosion-proof connection of sheet metal parts is made possible. Zur Lösung dieser Aufgabe wird deshalb vorgeschlagen, die Schaumstoffeinlagen als über die ganze Länge der Verbindung durchgehende Schaumstoffstreifen auszubilden und ihre nach dem Zusammenbau der Teile freien Flächen durch Randleisten abzudecken, die bei den in Lacktrockenöfen üblichen Temperaturen schmelzen und/oder aushärten und so eine Abdichtung der Schaumstoffstreifen gegen Feuchtigkeit usw. bewirken.To solve this problem it is therefore proposed that the foam inserts over the entire length the connection to form continuous foam strips and their after the assembly of the parts to cover free areas with edge strips that melt at the temperatures customary in paint drying ovens and / or harden, thus sealing the foam strips against moisture, etc. Schutz wird dabei nur für die Gesamtheit der im Anspruch enthaltenen Merkmale begehrt.Protection is only sought for the entirety of the features contained in the claim. Zur Verdeutlichung der Erfindung ist in der Zeichnung als Ausführungsbeispiel ein Schnitt durch eine Abdichtung zwischen Kotflügel und Radlaufblech eines Kraftwagens dargestellt.To illustrate the invention, a section is shown in the drawing as an exemplary embodiment a seal between the fender and wheel arch plate of a motor vehicle is shown. Zwischen dem Kotflügel 1 und dem Radlaufblech 2 ist ein über die ganze Länge der Verbindungsfläche reichender Schaumstoffstreifen 3 eingefügt, der in der vorstehend beschriebenen Weise behandelt ist. An seiner Ober- und Unterseite ist der Schaumstoffstreifen 3 jeweils durch eine Randleiste 4 abgedeckt, die durch Schmelzen bzw. Aushärten sowohl mit dem Schaumstoffstretfen 3 wie auch mit den Blechteilen 1 und 2 fest verbunden ist.Between the fender 1 and the wheel arch plate 2 is a over the entire length of the connecting surface Reaching foam strip 3 inserted, which is treated in the manner described above. At its top and bottom, the foam strip 3 is each covered by an edge strip 4, which by Melting or hardening both with the foam stripping 3 and with the sheet metal parts 1 and 2 connected is. Der Schaumstoffstreifen 3 kann dabei vorzugsweise aus Polyester- oder Polyäther-Schaumstoff bestehen, während für den Kleber bevorzugt gelöster Kautschuk oder künstliche Elastomere und Zellulose-Derivate in Frage kommen.The foam strip 3 can preferably consist of polyester or polyether foam, while for the adhesive preferred dissolved rubber or artificial elastomers and cellulose derivatives in Question come. Vorteilhafierweise können auf die nach dem Einbau an den Blechteilen 1 und 2 anliegenden Flächen der Schaumstoffstreifen 3 korrosionshemmende Stoffe, wie z. B. Zink oder Magnesium, aufgebracht werden.Advantageously, after installation on the sheet metal parts 1 and 2 surfaces of the Foam strips 3 corrosion-inhibiting substances, such as. B. zinc or magnesium are applied. Als Material für die Randleisten 4 kommen Polyvinylchloride oder ähnliche wärmeaushärtende Stoffe sowie Bitumen-Schmelzbänder in Frage.The material used for the edge strips 4 are polyvinyl chlorides or similar thermosetting ones Substances as well as bitumen melting strips in question.
