Description
Die Erfindung betrifft eine Einrastklaue zum Verbinden von Gerüstbauelementen, die aus einem einstückigen Metallblech geformt ist und in der ein Sicherungsfinger schwenkbar und mit einer Feder beaufschlagt gelagert ist.The invention relates to a latching claw for connecting scaffolding components, which consist of a one-piece Sheet metal is formed and in which a locking finger is pivotable and acted upon by a spring is stored.
Eine eingangs genannte Einrastklaue ist beispielsweise mit dem Gegenstand des DE-GM 71 28 051 bekannt geworden. Bei dieser bekannten Einrastklaue ist der Sicherungsfinger aus einem kostenaufwendigen Gußteil hergestellt.A latching claw mentioned at the outset is known, for example, from the subject of DE-GM 71 28 051. In this known latching claw, the locking finger is made from an expensive cast part.
Die Erfindung hat sich die Aufgabe gestellt, eine eingangs genannte Einrastklaue kostengünstiger herzustellen. The invention has set itself the task of producing a latching claw mentioned at the beginning more cost-effectively.
Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß der Sicherungsfinger aus einem plastikartigen Kunststoff besteht, in dem innen eine Metallzunge eingepreßt ist.To solve the problem, the invention is characterized in that the locking finger from consists of a plastic-like plastic, in which a metal tongue is pressed inside.
Mit der Herstellung des Sicherungsfingers aus einem plastikartigen Kunststoff wird der Vorteil erzielt, daß er sehr einfach und kostengünstig hergestellt werden kann. In der hochbelasteten Zone des Sicherungsfingers ist innen eine Metallzunge eingepreßt, welche die im Betrieb auftretenden Beanspruchungen aufnimmt.With the production of the securing finger from a plastic-like plastic, the advantage is achieved that he can be produced very easily and inexpensively. In the highly stressed zone of the locking finger is a metal tongue pressed in on the inside, which absorbs the stresses occurring during operation.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und näher erläutert. Es zeigtAn embodiment of the invention is shown and explained in more detail in the drawing. It shows

F i g. 2 die Draufsicht der F i g. 1 längs des Schnittes ll-il der Fig. 1 undF i g. 2 shows the top view of FIG. 1 along the section II-II of FIGS. 1 and
Fig.3 die Seitenansicht der Fig. 2 in einer Schnittdarstellung. 3 shows the side view of FIG. 2 in a sectional illustration.
Das Einrastgehäuse 10 wird einstückig aus einem Blech verformt und erhält so eine Faltung 11, daß eine handartige Einrastklaue (Fig. 1, 2, 3) entsteht. Diese — aus Stahl- oder Metallblech verformbare — Einrastklaue zeichnet sich dadurch aus, daß sie vorne an der Stirnseite eine Faltung 11 besitzt und daß sie auf der Rückseite zu einem röhrenartigen Anschlußstück 12 gepreßt ist; ferner sind zwei oder mehrere Löcher 13 in runder oder kantiger Form vorhanden, die dazu dienen, daß das anzuschließende Rohr zug- und druckfest eingepreßt werden kann. Bei dem Stanzvorgang werden die für die Montage nötigen Löcher 13 gleichzeitig mit eingepreßt und eingezogen.The snap-in housing 10 is formed in one piece from a sheet metal and is given a fold 11 that a hand-like latching claw (Fig. 1, 2, 3) is created. These - Deformable from sheet steel or sheet metal - snap-in claw is characterized by the fact that it is at the front of the Front side has a fold 11 and that it is pressed to form a tubular connection piece 12 on the rear side is; Furthermore, there are two or more holes 13 in a round or angular shape, which are used to that the pipe to be connected can be pressed in so that it is resistant to tension and pressure. During the punching process will be the holes 13 required for assembly are pressed in and drawn in at the same time.
Der mit einer Feder 17 beaufschlagte Sicherungsfinger 16 besteht aus gepreßtem Kunststoff (beispielsweise PVC). In den Sicherungsfinger 16 ist aus Sicherheitsgründen eine Metallzunge eingepreßt, welche die me- eo chanischen Beanspruchungen aufnimmt. Dieses Verfahren hat den Vorteil, daß es kostengünstig ist, daß es durch die eingepreßte Metallzunge sicher ist und daß es alle Bohrungen, Öffnungen und Passungen durch den Preßdruckvorgang mit genügender Präzision aufweist, μThe locking finger 16 acted upon by a spring 17 consists of pressed plastic (for example PVC). For safety reasons, a metal tongue is pressed into the securing finger 16, which the me- eo absorbs mechanical loads. This method has the advantage that it is inexpensive that it is safe by the pressed-in metal tongue and that there are all holes, openings and fits through the Having press printing process with sufficient precision, μ
