Mitteldeutsche Möbelfabrik, Akt-Ges. in Königslutter. Widerhaken für Zapfenverbindungen für Möbelteile.Central German furniture factory, Akt-Ges. in Königslutter. Barbs for mortise and tenon joints for furniture parts.
Es gibt Sicherungen von Zapfenverbindungen, die aus einem den Zapfen umgebenden Blechzylinder oder aus einer ihn umschließenden Blechklammer bestehen, bei denen das Blech mit ausgestanzten pyramidenartigen Erhöhungen versehen ist, die Widerhaken bilden, die das Herausziehen des Zapfens aus dem Zapfenloch erschweren.There are fuses of tenon joints that come from a surrounding the tenon Sheet metal cylinder or consist of a sheet metal clamp surrounding it, in which the sheet metal with punched-out pyramid-like Elevations is provided that form barbs that make it difficult to pull the pin out of the mortise.
Diesen Sicherungen gegenüber stellt der Gegenstand der Erfindung eine Vereinfachung dar, indem die Kosten dafür gering sind und die Anbringung einfacher ist, auch die Abmessungen des Zapfens keine anderen zu sein brauchen, als sie ohne die Anbringung der Sicherungsvorrichtung sind. Ein weiterer Vorteil ist, daß zwischen die Fläche des Holz-The subject matter of the invention simplifies these safeguards in that the cost thereof is low and the installation is easier, also the dimensions of the pin need not be other than they are without the attachment of the securing device. Another The advantage is that between the surface of the wooden
zapfens und die des Zapfenloches keine trennende »Metallschicht eingeschoben wird, so daß die. Berührung von Holz mit Holz erhalten bleibt.zapfens and the mortise no separating »metal layer is inserted, so that the. Contact of wood with wood is preserved.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt. Abb. ι zeigt den Zapfen von einer Seite, Abb. 2 von der rechtwinklig dazu liegenden Seite gesehen; Abb. 3 ist ein senkrechter Schnitt, Abb. 4 ein wagerechter Schnitt, beide gemäß der Abb. 1, wobei der Zapfen in seinem Loche dargestellt ist.An exemplary embodiment is shown in the drawing. Fig. Ι shows the pin seen from one side, Fig. 2 from the side lying at right angles thereto; Fig 3 is a vertical section, Fig. 4 a horizontal section, both according to Fig. 1, with the Pin is shown in its hole.
Nach dem neuen Verfahren wird in den Zapfen c seitlich ein messerartiges Plättchen d eingetrieben, das an seinem aus dem Zapfen herausragenden Teil eine nach dem Zapfenende zu schräg verlaufende Schneide e (Abb. 1) und auf der dem Zapfenende abgekehrten Seite eine etwa rechtwinklig zur Längsrichtung des Zapfens verlaufende undAccording to the new method, a knife-like plate d is driven laterally into the pin c , which has a cutting edge e (Fig. 1) that extends obliquely towards the pin end on its part protruding from the pin and an approximately right-angled to the longitudinal direction on the side facing away from the pin end of the journal and
so dadurch einen Widerhaken bildende Begrenzung/ besitzt, während es auf der in den Zapfen eindringenden Seite mit einer Spitze h versehen ist. Der mit dieser Einrichtung versehene Zapfen α (Abb. 1 und 2), der zylindrisch oder kegelförmig und im Querschnitt kreisförmig oder eckig sein kann, wird dann in das Zapfenloch i (Abb. 1) derart eingetrieben, daß sich das Plättchen d in Richtung der Holzfasern der Platte b erstreckt. Hierbei schneidet die messerartige Schneide e den Rand des Zapfenloches i auf, wie es die Abb. 4 erkennen läßt, jedoch schließt sich der Schnitt unterhalt) des Plättchens d so weit wieder, daß ein Herausziehen des Zapfens unmöglich wird. Abb. 3 stellt die fertige Verbindung im senkrechten Schnitt dar.thus thereby forming a barbed delimitation / has, while it is provided with a point h on the side penetrating into the pin. The pin provided with this device α (Fig. 1 and 2), which can be cylindrical or conical and circular or angular in cross-section, is then driven into the pin hole i (Fig. 1) in such a way that the plate d is in the direction of Wood fibers of the plate b extends. Here, the knife-like cutting edge e cuts the edge of the mortise i , as can be seen in Fig. 4, but the cut under) the plate d closes so far that it is impossible to pull out the tenon. Fig. 3 shows the finished connection in vertical section.
