Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Aufreihen von gelochten Blättern, bestehend aus einem mit einer buchförmigen Einbanddecke verbindbaren, federnden Mechanikdeckel, im Mechanikdeckel federnd abgestützten Tragteilen, sowie mindestens zwei aus Metalldraht hergestellten und jeweils aus zwei Ringhälften bestehenden Ringteilen, wobei die Ringhälften jedes Ringteiles einerseits an den Tragteilen befestigt sind und an ihren anderen, in Schließstellung aneinanderliegenden Enden mit in zwei verschiedenen Achsrichtungen verlaufenden und ineinandergreifenden Ausformungen versehen sind, wobei die ineinandergreifenden Ausformungen der Ringhälften als Verzahnungen mit in Schließstellung aneinanderliegenden, ebenen Flächen ausgebildet sind, wobei jeweils eine Ringhälfte mit einer zahnlückenartigen Vertiefung sowie einem in einer davon abweichenden Achsrichtung verlaufenden zahnartigen Vorsprung versehen ist, während die jeweils andere Ringhälfte mit einer entsprechend versetzten Vertiefung und einem entsprechend versetzten Vorsprung ausgestattet ist.The present invention relates to a device for lining up perforated sheets, consisting of a resilient mechanical cover which can be connected to a book-shaped cover, resiliently supported supporting parts in the mechanical cover, and at least two ring parts made of metal wire and each consisting of two ring halves, the ring halves of each ring part on the one hand are fastened to the supporting parts and are provided at their other ends, which are adjacent to one another in the closed position, with intermeshing formations running in two different axial directions, the intermeshing formations of the ring halves being designed as toothings with flat surfaces lying against one another in the closed position, whereby one ring half is provided with a tooth-gap-like depression and a tooth-like projection running in a different axial direction, while the other half of the ring is equipped with a correspondingly offset recess and a correspondingly offset projection.
Eine Vorrichtung der vorerwähnten Art ist aus der US-A 21 19 639 bekannt.A device of the aforementioned type is known from US-A 21 19 639.
Die dort gezeigte und beschriebene Vorrichtung ist im Bereich der in Schließstellung aneinanderliegenden Enden der Ringhälften mit einer Verzahnung versehen, deren Form durch jeweils keilförmige Kerben gekennzeichnet ist. Diese Kerben sind derart in die Enden der Ringhälften eingearbeitet, daß ihre Grundlinien einen spitzen Winkel zur Ringhälften-Achse bilden und in einem Punkt zusammenlaufen, der sich an einer vom äußeren oder vom freien Ende jeder Ringhälfte aus nach innen versetzten Stelle mit der Achse der jeweiligen Ringhälfte deckt. Die Innenseiten der Verzahnungen enthalten somit vier im wesentlichen dreieckige und ebene Flächen. Die ebenen Flächen bewirken beim Zusammenfügen der Ringhälften, daß im Falle einer Versetzung der beiden Ringhälften-Enden innerhalb normaler Grenzen die gegenseitige Führungswirkung der Flächen die Ringhälften-Enden in eine Flucht bringt, wobei die Federspannung, welche die Ringhälften zum Schließen bringt, für diesen Zweck ausreichend sein soll.The device shown and described there is provided with teeth in the region of the ends of the ring halves lying against one another in the closed position, the shape of which is characterized by wedge-shaped notches. These notches are worked into the ends of the ring halves in such a way that their base lines form an acute angle to the axis of the ring halves and converge at a point which is in a position offset from the outer or from the free end of each ring half with the axis of the respective one Half of the ring covers. The inside of the toothing thus contains four essentially triangular and flat surfaces. When the ring halves are joined together, the flat surfaces bring about that in the event of a displacement of the two ring halves ends within normal limits, the mutual guiding action of the surfaces aligns the ring halves ends, the spring tension which brings the ring halves to close for this purpose should be sufficient.
Es sind zum Beispiel aus der FR-A 478 925 oder der DE-C 350 693 auch Vorrichtungen zum Aufreihen von gelochten Blättern bekannt, bei denen das Verschieben der jeweils zusammenwirkenden Ringhälften gegeneinander und quer zur Schließrichtung verhindert ist. Bei derartigen Konstruktionen ist an einem Ende einer Ringhälfte ein senkrecht vorstehender Zapfen und an der anderen Ringhälfte eine zylindrische Bohrung vorgesehen, in die der Zapfen der anderen Ringhälfte in Schließstellung eingreift.From FR-A 478 925 or DE-C 350 693, for example, there are also devices for lining up perforations Scroll known, in which the displacement of the respective cooperating ring halves against each other and transverse to the closing direction is prevented. In such constructions, a vertically projecting pin is provided on one end of a ring half and a cylindrical bore is provided on the other half of the ring, into which the pin of the other ring half engages in the closed position.
Die vorerwähnte Konstruktion mit vorstehenden Zapfen einerseits und Bohrungen andererseits weist den Nachteil relativ aufwendiger Bearbeitungsmethoden auf, da die Anbringung der Zapfen und der entsprechenden Bohrungen letztendlich nur mit spanabhebenden Bearbeitungsmethoden möglich ist.The above-mentioned construction with protruding spigots on the one hand and bores on the other hand has the disadvantage of relatively complex machining methods, since ultimately the spigot and the corresponding bores can only be made with machining methods.
Auch die Gestaltung der Enden der Ringhälften gemäß der US-A-21 19 639 erfordert spanabhebende Bearbeitungsmethoden, da im Schließzustand der Verbindungsbereich zwischen den beiden Ringhälften frei sein soll von Vorsprüngen oder Kanten, das heißt, es soll eine glatte und durchgehende Form im Verbindungsbereich gegeben sein. Dies setzt eine exakte Bearbeitung der beiden Ringhälften-Enden notwendigerweise voraus.The design of the ends of the ring halves according to US-A-21 19 639 requires machining methods, since in the closed state the connection area between the two ring halves should be free of projections or edges, that is, there should be a smooth and continuous shape in the connection area be. This necessarily requires an exact machining of the two ring halves.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art dahingehend zu verbessern, daß eine Verschiebung der in Schließstellung zusammenwirkenden Ringhälften quer zur Schließrichtung verhindert wird und daß die dafür notwendigen Verformungen der betreffenden Enden der Ringhälften mit einfachen herstellungstechnischen Mitteln durchgeführt werden können.The present invention has for its object to improve a device of the generic type in such a way that a displacement of the ring halves cooperating in the closed position is prevented transversely to the closing direction and that the necessary deformations of the relevant ends of the ring halves can be carried out with simple manufacturing techniques.
Die Lösung dieser Aufgabe besteht darin, daß die in Schließstellung aneinanderliegenden ebenen Flächen der Verzahnung parallel beziehungsweise durch spanlose Formgebung bedingte minimale Abweichungen nahezu parallel zur Schließrichtung der beiden Ringhälften verlaufen.The solution to this problem is that the flat surfaces of the toothing lying against one another in the closed position run parallel or minimal deviations due to non-cutting shape almost parallel to the closing direction of the two ring halves.
Die Erfindung bringt den Vorteil mit sich, daß die im erfindungsgemäßen Sinne formschlüssig ineinandergreifenden Verzahnungen mit einfachen, herstellungstechnischen Mitteln angefertigt werden können, insbesondere können die Ringhälften durch spanlose Formgebung in der angegebenen Weise gestaltet werden. Dadurch ergibt sich gegenüber dem vorbekannten Stand der Technik eine erhebliche Fertigungsvereinfachung, ohne daß dadurch die angestrebte Wirkung, nämlich eine Verschiebung der jeweiligen Ringhälften gegeneinander und quer zur Schließrichtung zu verhindern, negativ beeinträchtigt wird.The invention has the advantage that the interlocking interlocking teeth in the sense of the invention can be produced with simple, manufacturing-technical means, in particular the ring halves can be designed in the manner indicated by non-cutting shaping. This results in a considerable simplification of production compared to the known prior art, without the desired effect, namely to prevent displacement of the respective ring halves against each other and transversely to the closing direction, is adversely affected.

In Fig. 1 ist in perspektivischer Darstellung eine vollständige Vorrichtung zum Aufreihen von gelochten Blättern dargestellt und insgesamt mit dem Bezugszeichen 10 versehen. Eine derartige Vorrichtung wird allgemein auch als Ringbuchmechanik bezeichnet.In Fig. 1, a complete device for lining up perforated sheets is shown in perspective view and overall provided with the
Die Vorrichtung 10 besteht im wesentlichen aus einem federnden Mechanikdeckel 11, darin federnd abgestützten Tragteilen 12 sowie aus mehreren Ringteilen 13, wobei jedes Ringteil 13 seinerseits aus zwei Ringhälften 13a und 13b besteht. Jede Ringhälfte 13a und 13b ist mit einem Ende an einem Tragteil 12 befestigt. Im geschlossenen Zustand bilden die beiden Ringhälften 13a und 13b einen geschlossenen Ring.The
Die Ringhälften 13a und 13b sind jeweils aus Metalldraht hergestellt.The ring halves 13a and 13b are each made of metal wire.
Um nun gelochte Blätter auf der in Fig. 1 vollständig dargestellten Vorrichtung aufzureihen, ist es zunächst erforderlich, die jeweiligen Ringteile 13 zu öffnen. Dies wird durch die Befestigung der jeweiligen Ringhälften 13a und 13b an den im Mechanikdeckel 11 federnd abgestützten Tragteilen 12 ermöglicht. Im geöffneten Zustand können auf die Ringhälften 13b gelochte Blätter aufgereiht werden, ist dies erfolgt, so wird durch Schließen der Ringteile 13 verhindert, daß die aufgereihten Blätter unbeabsichtigt entnommen werden können. Durch die ringförmige Gestaltung ist es ohne weiteres auch möglich, aufgereihte Blätter bei geschlossenen Ringteilen 13 vollständig umzublättern und auch wieder in die Ausgangslage zurückzubewegen.In order to line up perforated sheets on the device shown completely in FIG. 1, it is first necessary to open the
Um nun zu verhindern, daß die Ringhälften 13a und 13b der Ringteile 13 in Schließstellung quer zur Schließrichtung verschoben werden können, sind die Enden der jeweiligen Ringhälften 13a und 13b in besonderer Weise gestaltet.In order to prevent the ring halves 13a and 13b of the
Bei dem Ausführungsbeispiel der Neuerung nach den Fig. 2 sowie 4 bis 9 ist die Ringhälfte 13a mit einer zahnlückenartigen Vertiefung 14 sowie einem rechtwinklig dazu verlaufenden zahnartigen Vorsprung 15 ausgestattet. Der zahnartige Vorsprung 15 liegt im mittleren Bereich der Vertiefung 14.In the exemplary embodiment of the innovation according to FIGS. 2 and 4 to 9, the
Das gegenüberliegende Ende der Ringhälfte 13b ist mit einer gegenüber der Ausbildung der Ringhälfte 13a um 90o versetzten Ausbildung eines zahnartigen Vorsprunges 16 und einer entsprechenden zahnlückenartigen Vertiefung 17 ausgestattet, so daß sich im Schließzustand ein Formschluß zwischen den beiden Enden der Ringhälften 13a und 13b ergibt, der eine Verschiebung quer zur Schließrichtung der beiden Ringhälften 13a und 13b sicher verhindert.The opposite end of the
Die Verformungen der beiden Enden der Ringhälften 13a und 13b können spanlos durchgeführt werden, beispielsweise durch Stanzvorgänge.The deformations of the two ends of the ring halves 13a and 13b can be carried out without cutting, for example by punching processes.
Bei dem Ausführungsbeispiel der Neuerung gemäß den Fig. 3 sowie 10 bis 15 ist wiederum die Ringhälfte 13a mit einer zahnlückenartigen Vertiefung 14 ausgestattet. Rechtwinklig dazu weist das Ende der Ringhälfte 13a zahnartige Vorsprünge 15 auf, die sich versetzt zueinander zu beiden Seiten einer rechtwinklig zur Mittelachse der Vertiefung 14 verlaufenden gedachten Achse befinden.In the exemplary embodiment of the innovation according to FIGS. 3 and 10 to 15, the
Das Ende der Ringhälfte 13b ist mit einem zahnartigen Vorsprung 16 ausgestattet, der in die Vertiefung 14 der anderen Ringhälfte 13a eingreift. Weiterhin weist die Ringhälfte 13b in ihrem Endbereich zwei den Vorsprüngen 15 der anderen Ringhälfte 13a entsprechende Vertiefungen 17 auf. Die Vorsprünge 15 der Ringhälfte 13a greifen in Schließstellung in die Vertiefungen 17 der Ringhälfte 13b ein. Auch bei dieser Konstruktion ist eine Verschiebung der in Schließstellung befindlichen Ringhälften 13a und 13b quer zur Schließrichtung nicht mehr möglich. Darüber hinaus können auch die Vorsprünge 15 und 16 sowie die Vertiefungen 14 und 17 durch spanlose Formgebung angebracht werden.The end of the
