Aufgabe der Erfindung ist es, eine Ordnermechanik der eingangs genannten Art derart auszubilden, daß sie aus preiswert herstellbaren Kunststoffteilen zusammensetzbar ist, die leicht montierbar sind und welche eine einfache Positionierung und zuverlässige Verankerung der metallischen Aufreihstifte in den aus Kunststoff bestehenden Seitenteilen ermöglicht.The object of the invention is to provide a file mechanism of the type mentioned in such a way that it can be assembled from inexpensive plastic parts that are easy to assemble and that enables simple positioning and reliable anchoring of the metallic alignment pins in the plastic side parts.
Diese Aufgabe wird erfindungsgemäß mit den im Kennzeichnungsteil von Anspruch 1 angegebenen Merkmalen gelöst.This object is achieved with the features specified in the characterizing part of
Um eine zuverlässige Befestigung der Aufreihstifte mit den aus Kunststoff bestehenden Seitenteilen zu erreichen, sind die beiden bogenförmigen Aufreihstifte eines Seitenteils einstückig miteinander verbunden und rechtwinklig von dem jeweils verbindenden Teil abgewinkelt. Die Seitenteile haben im Abstand der bogenförmigen Aufreihstifte Löcher, durch welche die Aufreihstifte von der Rückseite der Seitenteile aus hindurchgeführt sind. An der Rückseite der Seitenteile befindet sich zur Aufnahme des verbindenden Teils der Aufreihstifte eine Nut. In diese Nut kann der verbindende Teil der Aufreihstifte eingeklebt, eingeschweißt oder eingeklemmt werden. Zweckmäßigerweise ist jedes Seitenteil mit vier Löchern zum Hindurchführen von Aufreihstiften versehen. Die Löcher haben einen Abstand voneinander sowie einen Querschnitt, der es ermöglicht, jedes Seitenteil mit Aufreihstiften für eine Zweilochmechanik oder aber auch für eine Vierlochmechanik auszustatten.In order to achieve a reliable fastening of the alignment pins with the side parts made of plastic, the two arch-shaped alignment pins of one side part are connected to one another in one piece and angled at right angles from the respectively connecting part. The side parts have holes at a distance from the arch-shaped alignment pins, through which holes the alignment pins are passed from the rear of the side parts. There is a groove on the back of the side parts to accommodate the connecting part of the alignment pins. The connecting part of the alignment pins can be glued, welded or clamped into this groove. Each side part is expediently provided with four holes for the passage of alignment pins. The holes are spaced from one another and have a cross section that makes it possible to equip each side part with alignment pins for a two-hole mechanism or else for a four-hole mechanism.
Um die beiden Seitenteile zusammen mit dem Hebel in Sperrstellung verschwenken zu können, ist der Lagerbock des Hebels an einer U-förmigen Schwinge angeordnet, die um die gemeinsame Schwenkachse der Seitenteile schwenkbar gelagert ist. Auch bei dieser Ausführungsform kann die Schwinge und der daran angeformte Lagerbock sowie der darin gelagerte Hebel aus Kunststoff hergestellt sein.In order to be able to pivot the two side parts together with the lever in the locked position, the bearing block of the lever is arranged on a U-shaped rocker which is pivotably mounted about the common pivot axis of the side parts. In this embodiment too, the rocker and the bearing block formed thereon and the lever mounted therein can be made of plastic.
Bei einer vorteilhaften Ausführungsform der Erfindung besteht der Hebel aus Kunststoff und am Hebel ist eine sich gegen ein Widerlager abstützende Rückstellfeder angeformt, welche den Hebel in einer die Seitenteile in Schließstellung haltenden Sperrstellung hält.In an advantageous embodiment of the invention, the lever is made of plastic and on the lever a return spring is formed which is supported against an abutment and which holds the lever in a blocking position holding the side parts in the closed position.
Weitere Merkmale der Erfindung ergeben sich aus den Schutzansprüchen.Further features of the invention emerge from the protection claims.

Wie die Fig. 1 bis 3 zeigen, setzt sich die Ordnermechanik zusammen aus einer Grundplatte 1 mit Lagerböckchen 2 und 3, den Seitenteilen 4 und 5, die gemeinsam um die Achse 8 schwenkbar an den Lagerböckchen 2 und 3 gelagert sind, und welche gebogene Aufreihstifte 6, 6', 7,7' aufweisen, auf welche gelochte Blätter aufgereiht werden können. Die Fig. 1 und 2 zeigen die Ordnermechanik mit in Öffnungsstellung befindlichen Seitenteilen 4 und 5. In dieser Öffnungsstellung der Seitenteile 4 und 5 haben die Spitzen der gebogenen Aufreihstifte 6,7 bzw. 6', 7' einen Abstand Voneinander, so daß mit Zwei Löchern gelochte Blätter auf diese Aufreihstifte 6,6',7,7' aufgereiht werden können oder von diesen Aufreihstiften abgenommen werden können.As shown in FIGS. 1 to 3, the folder mechanism is composed of a
In der nicht dargestellten Schließstellung überlappen die Spitzen der jeweils zusammenwirkenden Aufreihstifte 6,7 und 6',7', so daß die Blätter unverlierbar gehalten sind. In dieser Schließstellung wird der Hebel 9 von einer Rückstellfeder in eine Blockierstellung gedrückt, in welcher der Sperrblock 21 sich zwischen zwei Anschlagflächen 22 und 23 der Seitenteile 4 und 5 legt und ein selbsttätiges Öffnen der Ordnermechanik verhindert. Der Hebel 9 kann durch Herunterdrücken von Hand in eine die Seitenteile 4 und 5 freigebende Öffnungsstellung bewegt werden, so daß diese in die aus Fig. 1 und 2 ersichtliche Stellung gelangen.In the closed position, not shown, the tips of the respective
Die Grundplatte 1 mit den Lagerböckchen 2 und 3 ist aus Kunststoff hergestellt und ist einstückig mit den Lagerböckchen 2 und 3 verbunden. Auch die Seitenteile 4 und 5 bestehen aus Kunststoff. An ihnen sind aus Stahl hergestellte bogenförmige Aufreihstifte 6,6' und 7,7' befestigt. Die dargestellte Ordnermechanik ist als Zweilochmechanik ausgebildet, bei der die jeweils zusammenwirkenden Aufreihstifte 6,7 bzw. 6',7' halbkreisförmige Querschnitte aufweis en, die sich im Bereich der Überlappung der Aufreihstifte zu einem Kreisquerschnitt ergänzen.The
Die bogenförmigen Aufreihstifte 6,6' und 7,7' der Seitenteile 4 und 5 sind einstückig miteinander verbunden und rechtwinklig von dem jeweils verbindenden Teil 20 abgewinkelt. Der verbindende Teil 20 ist an der Rückseite der Seitenteile 4 und 5 in eine dort eingeformte Nut untergebracht. Diese Mut verbindet die Löcher in den Seitenteilen 4 und 5, durch welche die Aufreihstifte 6,6' und 7,7' gesteckt sind. Der verbindende Teil 20 der Aufreihstifte 6,6' und 7,7' kann in der Nut der Seitenteile 4,5 eingeklebt, eingeklemmt oder eingeschweißt sein. Dies hat den Vorteil, daß die Seitenteile 4 und 5 nachträglich mit den Aufreihern 6,6',7,7' ausgerüstet werden können. Die Seitenteile können auch so ausgestaltet sein und mit einer Nut versehen sein, daß sowohl die Aufreihstifte für eine Zweilochmechanik als auch die Aufreihstifte für eine Vierlochmechanik an diesen Seitenteilen angebracht werden können. Bei einer Vierlochmechanik haben die Aufreihstifte einen kreisförmigen Querschnitt und die Aufreihstifte eines Seitenteils haben beispielsweise einen Abstand von 8 cm, während die Aufreihstifte des anderen Seitenteils beispielsweise einen Abstand von 6 cm voneinander haben und zu den Aufreihstiften des ersten Seitenteils um 1 cm nach innen versetzt sind. Bei dieser Vierlochmechanik ist der Querschnitt der Aufreihstifte rund.The arc-
Es ist auch möglich, daß der Kunststoff, aus dem die Seitenteile bestehen, um die in einer Spritzform eingesetzten Aufreihstifte und deren Verbindungsteil gespritzt ist.It is also possible for the plastic from which the side parts are made to be molded around the alignment pins used in an injection mold and their connecting part.
Bei einer einfachen Ausführungsform der Erfindung ist der Lagerbock für den Hebel 9 unmittelbar an der Grundplatte 1 angeformt. In diesem Lagerbock ist der Hebel 9 um die Achse 17 schwenkbar eingerastet.In a simple embodiment of the invention, the bearing block for the
Bei dem in den Fig. 1 bis 5 dargestellten Ausführungsbeispiel ist jedoch der Hebel 9 an einer um die Achse 8 schwenkbar gelagerten U-förmigen Schwinge 10 angeordnet. Diese Schwinge 10 weist nach oben abgewinkelte Wangen 11 und 12 auf, in denen Zapfen 13 und 14 gelagert sind, die von den Lagerböckchen 3 und 2 gehalten sind. Damit die Ordnermechanik kompakt und niedrig bleiben kann, ist die Grundplatte 1 rahmenartig ausgebildet und weist eine längliche Ausnehmung 15 auf, in welcher die Schwinge 10 zumindest teilweise untergebracht ist. Damit die Schwinge um die Achse 8 schwenken kann, sind die oberen Längskanten der Ausnehmung 15 und die unteren Längskanten der Schwinge 10 in einem Winkel von ca. 30 bis 40° gleichsinnig zueinander abgeschrägt. Diese Abschrägungen 25 und 27 sind insbesondere aus Fig. 3 erkennbar.In the embodiment shown in FIGS. 1 to 5, however, the
Wie die Fig. 3 und 4 zeigen, ist an der Schwinge 10 ein Lagerbock 16 für den Hebel 9 angeformt, in dem der Hebel 9 um die Achse 17 schwenkbar einrastbar ist. Das Einrasten kann dadurch geschehen, daß die Lageraugen des Lagerbocks 16 spreizbar sind oder aber auch die am Hebel 9 befindlichen Lagerzapfen etwas nach innen gedrückt werden können.3 and 4 show, a
Wie die Fig. 4 zeigt, besteht der Hebel 9 mit dem Sperrblock 21 aus Kunststoff. Mit diesem Hebel 9 ist einstückig eine Rückstellfeder 18 verbunden, die als federnde Zunge ausgebildet ist und die sich am Lagerbock 16 gegen ein Widerlager 19 abstützt. Der Sperrblock 21 kann dadurch in eine Öffnungsstellung bewegt werden, daß der Hebel 9 an der Griffmulde 29 nach unten gedrückt wird. Dabei wird die elastische Zunge der Rückstellfeder 18 verformt und der Sperrblock 21 bewegt sich über die einander zugewandten Kanten der Seitenteile, so daß diese geöffnet werden können. Die Rückstellfeder 18 drückt selbsttätig den Hebel 9 mit dem Sperrblock 21 in Sperrstellung. Durch Zuklappen des Ordners werden die Seitenteile in die Schließstellung bewegt, so daß sich der Sperrblock 21 zwischen die Anschlagflächen 22 und 23 der Seitenteile 4 und 5 legen kann.As shown in FIG. 4, the
Bei der Ausführungsform nach Fig. 5 ist der Hebel 9 einstückig mit der Schwinge 10 verbunden. Während bei der Ausführungsform nach Fig. 4 die Griffmulde 29 nach unten gedrückt werden mußte, um den Sperrblock 21 anzuheben, muß bei der Ausführungsform der Fig. 5 die Griffmulde 29 des Hebels 9 angehoben werden, um den Sperrblock 21 anzuheben. Die Rückstellfeder wird hier von einem federnden zungenförmigen Teil 31 gebildet, der den Hebel 9 einstückig mit der Schwinge 10 verbindet.5, the
Damit sich diese Ordnermechanik aus möglichst wenigen Teilen zusammensetzt, kann es zweckmäßig sein, einen Zapfen an einen der beiden Lagerböckchen 2 oder 3 anzuformen und den anderen Zapfen an einer Wange 11 oder 12 eines Seitenteils 4 oder 5 oder einer Wange 24,25 der Schwinge anzuformen. Die Zapfen 13 oder 14 können aber auch bei der Montage der Teile in die Öffnungen der Lagerböckchen 3 und 2 und der Wangen 24,25 in den Seitenteilen 4 und 5 sowie in den Wangen 11 und 12 der Schwinge 10 eingeschoben und durch Verschweißen oder Verkleben an den Lagerböckchen 3 und 2 befestigt werden.So that this folder mechanism is made up of as few parts as possible, it can be useful to form a pin on one of the two
