Abstract

The weld seam (1) has the protruding metal edge stamped into tags (4) spaced along it. The tags are cut and bent in one simple tooling operation. A U-shaped elastic strip (7) is clipped over the seam. The strip is reinforced with an insert layer (8) and has a ratchet strip (9) on one side, to clip under the tags. No special rolling is required for the seam edges in the car body, only the simple tag cutting. The cover strip is not easily torn off nor deflected laterally. It provides good protection from the sharp seam edge.

Description

Anordnung mit einem Flansch und einem den Randbereich dieses Flansches abdeckenden Keder Die Erfindung betrifft eine Anordnung mit einem Flansch und einem den Randbereich dieses Flansches abdeckenden elastischen Keder, der - im Querschnitt etwa U-förmig und auf seiner Innenseite mit wenigstens einer widerhakenförmigen Nase versehen -auf den Rand des Flansches aufgeschoben ist, wobei er mit seiner Nase einen am Flansch befindlichen Vorsprung hintergreift. Arrangement with a flange and the edge area of this flange covering piping The invention relates to an arrangement with a flange and a the edge area of this flange covering elastic piping, which - in cross section approximately U-shaped and on its inside with at least one barb-shaped Nose provided - is pushed onto the edge of the flange, with his Nose engages behind a projection located on the flange.

Derartige Anordnungen sind insbesondere im Karosseriebau üblich, um frei liegende Blechkanten, an denen man sich leicht verletzen könnte, zu entscharfen. Bei einer bekannten Anordnung dieser Art (US-PS 2 704 688) ist das freie Ende des zunächst aus zwei aufeinanderliegenden Blechstreifen bestehenden Flansches durch Umbiegen eines dieser Blechstreifen um 1800 aufgedickt. Dieses umgebogene Ende, das den Flansch nur auf einem Teil seiner Breite überdeckt, bildet zugleich den Vorsprung am Flansch, gegen den sich der aufgeschobene Keder abstützt, der somit gegen Abrutschen gesichert ist. Diese bekannte Anordnung läßt sich mit Vorteil immer dann anwenden, wenn die beiden den Flansch bildenden Blechstreifen aus Festigkeits- oder Dichtungsgründen nicht miteinander verschweißt werden müssen, weil die Umbördolung die beiden Blechteile hinreichend mit eine ander verbindet. Diese bekannte Konstruktion ist jedoch aufwendig, weil das Umbördeln in mehreren Arbeitsfolgen durchgeführt werden muß. Insbesondere in den Fällen, in denen der Flansch von nur einem einzigen Blechstreifen gebildet wird oder in denen der Flansch von zwei Blechstreifen gebildet wird, die aber aus Festigkeitsgründen ohnehin miteinander verschweißt werden müssen, die Umbördelung also in festigkeitsmäßiger Hinsicht keinerlei Funktion mehr hat, ist diese bekannte Anordnung, bei der der Flansch zunächst fertig beschnitten und dann in weiteren separaten Arbeitsgängen umgebördelt werden muß, sehr arbeitsaufwendig. Der Erfindung liegt die Aufgabe zugrunde, eine Anordnung der eingangs genannten Art zu schaffen, die wesentlich einfacher und schneller herzustellen ist als bekannte Anordnungen, ohne daß der Festsitz des Keders dadurch beeinträchtigt wird. Die diese Aufgabe lösende Erfindung besteht darin, daß der Vorsprung im Flansch durch örtliches Ausstellen während des abschließenden Beschneidevorganges gewonnen ist.Such arrangements are common in particular in the body shop to to defuse exposed sheet metal edges that could easily injure yourself. In a known arrangement of this type (US-PS 2,704,688) the free end of the first made of two superimposed sheet metal strips through the existing flange Bending one of these sheet metal strips thickened around 1800. This bent end which covers the flange only on part of its width, at the same time forms the Protrusion on the flange, against which the pushed-on piping is supported, which thus is secured against slipping. This known arrangement can always be advantageous use when the two sheet metal strips forming the flange are made of strength or sealing reasons do not have to be welded together, because the bead sufficiently connects the two sheet metal parts with one another. These known construction is expensive, however, because the flanging takes place in several work sequences must be carried out. Especially in cases where the flange of only a single sheet metal strip is formed or in which the flange is formed by two sheet metal strips is formed, which are welded to one another anyway for reasons of strength must, so the flanging no longer has any function in terms of strength has this known arrangement, in which the flange is first cut completely and then has to be flanged in further separate operations, very labor-intensive. The invention is based on the object of providing an arrangement of the type mentioned at the beginning To create a kind that is much easier and faster to manufacture than known ones Arrangements without affecting the tight fit of the welt. The this The object of the invention is that the projection in the flange by local Exhibiting is gained during the final trimming process.

Ausstellen in diesem Sinne kann ein Ausklinkcl oder Ausdrücken bedeuten. Beim Ausklinken werden örtlich, d. h. in bestimmten Abständen entlang des Flansches, paarweise, den jeweiligen späteren Vorsprung seitlich begrenzende Einschnitte angebracht und die zwischen ihnen liegenden Abschnitte aufgebogen. Beim Ausrücken werden die. entsprechenden Abschnitte, ohne daß der Flansch zuvor eingeschnitten wird, aus dessen Ebene herausgedrückt. Das Ausklinken bzwç stattdessen das Ausdrücken wird in demselben Arbeitsgang mit ausgeführt, in dem der Flansch abschließend beschnitten wird0 Dadurch liegen bei dem fertig geformten und beschnittenen Flansch der Rand des Flansches und der Rand des ausgestellten Teils in gleicher Röhe. Dies hat zur Folge, daß der aufgesteckte Keder nicht seitlich wegkippen kann, was sonst den optischen Eindruck der Anordnung stark schmälern würde. Natürlich bedingt die erfindungsgemäße, vereinfachte herstellung (Beschneiden des Flansches und gleichzeitige Schaffi des Vorsprunges) einen nicht zu übersehenden wirtschaftlichen Vorteil.Issuing in this sense can mean a notch or expression. When notching, local, i. H. at certain intervals along the flange, in pairs, incisions laterally delimiting the respective later projection and the sections lying between them are bent up. When moving out, the. corresponding sections, without the flange is previously cut, from its Level pushed out. The notching or instead the expressing is done in the same Work step is also carried out in which the flange is finally trimmed 0 As a result the edge of the flange lies at the finished formed and trimmed flange and the edge of the exhibited part in the same depth. This has the consequence that the attached piping cannot tip sideways, which would otherwise reduce the optical impression would greatly diminish the arrangement. Naturally conditionally the invention, Simplified production (trimming of the flange and simultaneous cutting of the Advantage) an economic advantage that cannot be overlooked.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung im folgenden näher eSäutert.An embodiment of the invention is based on the drawing in following closer eSäutert.

Die Figur zeigt in stark vergrößert er Darstellung den Querschnitt durch einen erfindungsgemäß ausgebildeten Karosserieflansch und einen darüber geschobenen Keder.The figure shows the cross section in a greatly enlarged representation by a body flange designed according to the invention and one pushed over it Piping.

Der Flansch 1 besteht aus einem einlagigen Blech, das innerhalb desselben Arbeitsganges, in welchem es an seinem freien Rand 2 auf MaB geschnitten wurde, mit senkrecht zur Längskante verlaufenden Einschnitten 3 versehen ist, die sich abwechselnd in kürzeren und längeren Abständen längs des Flansches wiederholen. Die zwischen zwei in kürzeren Abständen aufeinander folgendenEinschnitt liegenden Abschnitte 4 sind aus der Ebene des Flansches ausgeklinkt> noch bevor die freie Kante des Flansches beschnitten wurde. Dadurch liegen die freien Enden 5 und 6 des eigentlIchen Flansches im Bereich des Einschnitts 3 und des Abschnitts 4 sozusagen auf gleicher Höhe, Dies ist wichtig für einen ordentlichen Sitz des anschließend über den Flansch 1 geschobenen U-förmigen Leders 7e Der Keder 7 besteht aus einem elastischen Kunststoff und einer versteifenden Metalleinlage 8. Die Metalleinlage 8 kann in diesem Falle aus einem Material minderer Qualität bestehen, zumindest braucht es kein Federstahl zu sein, denn die meistens angestrebte Federwirkung des Leders braucht in diesem Falle nicht so stark ausgeprägt zu sein, weil der Keder 7 formschlüssig mit dem Flansch 1 verbunden ist. Dieser Formschluß wird erreicht durch den Abschnitt 4 des Ylansches 1 (den Vorsprung) und die Nase 9 am Keder 7, die einander hintergreifen.The flange 1 consists of a single-layer sheet metal inside the same Operation in which it was cut to size on its free edge 2, is provided with incisions 3 extending perpendicular to the longitudinal edge, which Repeat alternately at shorter and longer intervals along the flange. Those lying between two consecutive incisions at shorter intervals Sections 4 are notched out of the plane of the flange> even before the free Edge of the flange has been trimmed. As a result, the free ends 5 and 6 of the actual flange in the area of the incision 3 and the section 4, so to speak at the same height, this is important for a proper fit of the subsequently U-shaped leather 7e pushed over the flange 1 The piping 7 consists of a elastic plastic and a stiffening metal insert 8. The metal insert 8 can in this case consist of a material of inferior quality, at least it does not need to be spring steel, because the spring effect of the In this case, the leather does not need to be so pronounced because the piping 7 is positively connected to the flange 1. This form fit is achieved through the section 4 of the Ylansches 1 (the projection) and the nose 9 on the piping 7, that reach behind each other.
