Description

Schnellhefter mit Druckknöpfen. Die Erfindung betrifft die Herstellung des Unterknopfes (Aufreihstengels) und die Befestigung des Oberknopfes bei Schnellheftern mit Druckknöpfen durch Spritzguß zwecks Vereinfachung der Herstellung.Flat file with press studs. The invention relates to manufacture of the lower button (rowing handle) and the fastening of the upper button for flat files with snap fasteners by injection molding to simplify manufacture.

Der technische Fortschritt ist neben der sehr wesentlichen Verbilligung darin zu erblicken, daß der bisher aus mindestens zwei Teilen, dem gedrehten Schaftstengel mit Kugelkopf und einer Unterlegscheibe bestehende Aufreihstengel in einem einzigen Arbeitsgange auf den Boden des Schnellhefters angegossen wird, während gleichzeitig in demselben Arbeits-Bange der Federdruckknopfoberteil durch Anguß am Deckel des Hefters angegossen wird.The technical progress is next to the very substantial cheaper it can be seen that the so far consists of at least two parts, the twisted shaft stem with a ball head and a washer in a single row Work aisles on the bottom of the flat file is poured while at the same time in the same work-anxiety of the spring push button top part by sprue on the lid of the Stapler is cast on.

Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.The invention is shown in an exemplary embodiment in the drawing.

Die Stellen, wo die beiden Stengel 2 auf dem Boden des Hefters r zu stehen kommen, werden zunächst gelocht. Das Loch ist annähernd so groß wie der Querschnitt des Stengelschaftes 2. In gleicher Weise werden die Stellen, an denen die Knöpfe befestigt werden sollen, mit j e einem Loch versehen, das so groß ist, daß es den über die Oberkante des bekannten Federdruckknopfes (Koh-i-noor) hinausragenden Teil, die Haube 3, fest umschließt.The places where the two stalks 2 on the bottom of the stapler r to come, are first punched. The hole is approximately as large as the cross-section of the stem shaft 2. In the same way are the places where the buttons are to be attached, each provided with a hole that is so large that it is the over the upper edge of the well-known spring push button (Koh-i-noor) protruding part, the hood 3, tightly encloses.

In einer entsprechenden Gießmaschine werden die beiden Aufreihdruckknopfpaare dergestalt direkt auf den Deckel des Schnellhefters angegossen, daß der Gußkopf 6 den Oberknopf 5 festhält, indem er mit der Haube 3 verlötet wird, während der Fuß q. des Aufreihstengels 2 am Boden des Hefters wie ein Niet durchgreifend haftet.The two pairs of snap fasteners are placed in a corresponding casting machine molded directly onto the lid of the folder in such a way that the casting head 6 holds the top button 5 by soldering it to the hood 3, during the Foot q. of the leaning handle 2 adheres to the bottom of the stapler like a rivet.
