Abstract

The invention relates to an expanding rivet for the attachment of perforated metal sheets, plates and the like to an expanding body which is provided at the upper end with a flange which is closed like an annulus and has opposite studs in the cavity and an expanding strip which can be inserted into the expanding body. In order to create an expanding rivet which has both improved adhesion within the parts to be connected as well as improved security against detachment, it is proposed that the expanding body be open at the lower end and that in each case two opposite studs be arranged on the inner surfaces of the expanding body, which studs have oblique surfaces towards the closed end, the studs (5) being larger in length and thickness than the studs (4). <IMAGE>

Description

Die Erfindung betrifft einen Spreizniet zur BefestigungThe invention relates to an expanding rivet for fastening

von gelochten Blechen, Platten und dergleichen, gemäß dem Oberbegriff des Patentanspruchs 1.of perforated sheets, plates and the like, according to the preamble of claim 1.

Es sind Spreiznieten bekannt, die einen unten geschlossenen Spreizteil und innen Nocken aufweisen (DE-GM 19 42 368Y.Expanding rivets are known which have an expanding part closed at the bottom and have cams on the inside (DE-GM 19 42 368Y.

Nachteilig bei dieser Ausführung ist, daß ein fester Sitz in den zu verbindenden Teilen nicht gewährleistet werden kant.The disadvantage of this design is that a tight fit in the too connecting parts cannot be guaranteed.

Aufgabe der Erfindung ist es einen Spreizniet zu schaffen, der sowohl eine verbesserte Haftung innerhalb der zu verbindenden Teile als auch eine verbesserte Sicherung gegen Lösen aufweist.The object of the invention is to create an expanding rivet that both an improved adhesion within the parts to be connected as well as an improved one Has securing against loosening.

Zur Lösung dieser Aufgabe wird erfindungsgemäß ein Spreizniet vorgeschlagen, wie er im Patentanspruch 1 beschrieben ist.To solve this problem, an expanding rivet is proposed according to the invention, as described in claim 1.

Der erfindungsgemäße Spreizniet erzielt durch die oberen Nocken eine verstärkte Halterung durch Erhöhung des Lochleibungsdruckes innerhalb der zu verbindenden Teile und garantiert einen festen Sitz durch die vergrößerten am offenen Ende der Spreizarme befindlichen Nocken.The expanding rivet according to the invention achieved a through the upper cams Reinforced mounting by increasing the embedment pressure within the to be connected Parts and guarantees a tight fit thanks to the enlarged at the open end of the Spreading arms located cams.

Durch die Anordnung der beiden Nockenpaare ist der Dickenbereich der zu verbindenden gelochten Bleche wesentlich erhöht. Bei dünnen Blechen kommt das obere Nockenpaar zum Einsatz, bei dicken Blechen beide Nockenpaare.Due to the arrangement of the two pairs of cams, the thickness range is the perforated sheets to be connected significantly increased. This is the case with thin sheet metal Upper pair of cams used, with thick sheets both pairs of cams.

Die Herstellung kann einteilig erfolgen mit Übergängen vom Spreizkörper zur Spreizleiste oder auch in zwei Einzelteilen, wobei die Spreizleiste im Spreizkörper gehalten wird.The production can be done in one piece with transitions from the expansion body for expanding bar or in two individual parts, with the expanding bar in the expanding body is held.

In den beigefügten Zeichnungen ist eine mögliche Ausfiülrungsform eines erSindungsgemaRen Spreizniets schematisch dargestellt.One possible embodiment is shown in the accompanying drawings an inventive expanding rivet shown schematically.

Es zeigen: Fig. 1 eine Vorderansicht im Schnitt Fig. 2 eine Draufsicht Fig. 3 Anwendungsbeispiele Fig. 4) Aus Fig. 1 ist ersichtlich, daß der Spreizkörper 1 unten offengehalten und oben mit einem Flansch 2 ausgestattet ist. Die Innenflächen 3 der Spreizarme 7 sind mit äe zwei sich gegenüberliegenden Nocken 4 und 5 versehen. Diese Nocken sind zum geschlossenen Ende hin mit Abschrägungen 6 -ausgestattet, wobei die Nocken 5 in Länge und Dicke vorzugsweise 1,5 fach größer sind als die Nocken 4.They show: FIG. 1 a front view in section. FIG. 2 a plan view Fig. 3 application examples Fig. 4) From Fig. 1 it can be seen that the expansion body 1 is kept open at the bottom and is equipped with a flange 2 at the top. The inner surfaces 3 of the spreading arms 7 are provided with two opposing cams 4 and 5. These cams are equipped with bevels 6 towards the closed end, wherein the cams 5 are preferably 1.5 times larger than the length and thickness Cam 4.

In dem Schlitz 9 des Spreizkörpers 1 sitzt eine diesem Schlitz angepaßte Spreiieiste 8, die zur Befestigung des Spreizniets in den zu verbindenden Teilen (sh. Figur 3 und 4) in das Innere eingedrückt wird. In the slot 9 of the expansion body 1 sits a split bar 8 which is adapted to this slot and which is pressed into the interior for fastening the expanding rivet in the parts to be connected (see FIGS. 3 and 4).
