Abstract

The ring binder mechanism comprises a resilient mechanism cover which can be connected to the spine of a binder or cover, two toggle plates or toggle rods which are articulately connected in opposite senses and which are resiliently supported in the mechanism cover, and ring portions which cooperate in pairs to form rings and which are carried by the toggle plates or toggle rods, consist of drawn or rolled metal wire of non-round cross-section and have ends which positively interengage locally in the closed position. At their free ends, the ring portions have plane end faces which bear snugly against one another in the closed position and one ring portion of each pair of ring portions having a pin which is cylindrical over at least its main length and which projects perpendicularly from the end face and the other ring portion having a bore which is cylindrical over at least its main length and is sunk perpendicularly in the end face.

Description

Die Erfindung bezieht sich auf eine Ringbuchmechanik in einer Ausbildung nach dem Oberbegriff des Anspruchs 1.The invention relates to a ring binder mechanism in an embodiment according to the preamble of claim 1.

Bei bekannten Ringbuchmechaniken dieser Art (DE-A-31 33 845) greifen die freien Enden der Ringteile mit einer Verzahnung spaltfrei ineinander, so daß die durch die Federspannung des Mechanik-Deckels aneinander gepreßten Enden der Ringteile in einer Ebene justiert sind. Eine solche Ausführung gestattet zwar eine wirtschaftliche Fertigung, hat jedoch den Nachteil, daß ein Versatz der Enden der Ringteile quer zur Justierungsebene möglich ist. Bei Ringbuchmechaniken mit einem relativ großen Fassungvermögen an gelochtem Schriftgut, bei denen die Ringteile eine entsprechend große Abmessung haben, reicht die Federvorspannung des Mechanikdekkels oft nicht aus, die beiden Ringteile zuverlässig aneinander zu pressen und vor einem Ausrasten aus der gegenseitigen Verzahnung zu sichern.In known ring binder mechanisms of this type (DE-A-31 33 845), the free ends of the ring parts engage with one another without a gap, so that the ends of the ring parts pressed against one another by the spring tension of the mechanical cover are adjusted in one plane. Although such an embodiment allows economical production, it has the disadvantage that the ends of the ring parts can be offset transversely to the adjustment plane. In ring binder mechanisms with a relatively large capacity for perforated documents, in which the ring parts have a correspondingly large dimension, the spring preload of the mechanical cover is often not sufficient to reliably press the two ring parts against one another and to secure them against disengagement from the mutual toothing.

Es sind ferner Ringbuchmechaniken der eingangs genannten Art mit Ringteilen aus Metalldraht runden Querschnitts bekannt (GB-A-190 860), bei denen ein Ringteil eines jeden Ringteilepaares an seinem Ende konisch zugeschärft und das Ende des anderen Ringteils mit einer konischen Einsenkung versehen ist. Der formschlüssige Eingriff derartiger Ringteileenden gewährleistet zwar eine gegenseitige Justierung der Ringteileenden in allen Richtungen, jedoch reicht der vom Mechanikdeckel auf die Ringteileenden ausgeübte Anpreßdruck nicht aus, um bei Drücken quer zur Ebene der Ringteile ein Lösen des gegenseitigen Eingriffs zuverlässig zu verhindern.There are also ring binder mechanisms of the type mentioned with ring parts made of metal wire with a round cross-section (GB-A-190 860), in which one ring part of each pair of ring parts is conically sharpened at its end and the end of the other ring part is provided with a conical depression. The form-fitting engagement of such ring part ends ensures mutual adjustment of the ring part ends in all directions, but the contact pressure exerted by the mechanical cover on the ring part ends is not sufficient to reliably prevent the mutual engagement from being released at pressures transverse to the plane of the ring parts.

Dies gilt auch für Ringmechaniken, bei denen Ringteile unrunden Querschnitts aus Kunststoff gespritzt und endseitig mit einem konischen Ansatz bzw. einer konischen Bohrung versehen sind (CH-A-433 187). Abgesehen davon weisen Kunststoff-Ringteile eine nur geringe Eigensteifigkeit auf, die Verlagerungen der Enden der Ringteile Vorschub leistet.This also applies to ring mechanisms in which ring parts with a non-circular cross-section are injection molded from plastic and provided with a conical shoulder or a conical bore at the end (CH-A-433 187). Apart from this, plastic ring parts have only a low intrinsic rigidity, which promotes displacement of the ends of the ring parts.

Bei einer Hubkugelmechanik (DE-A-563 549) weisen die zum Öffnen vor einem Schwenken eine Hubbewegung ausführenden Bügel einen endseitigen Zapfen auf, der in eine Bohrung im oberen Ende von Aufreihstiften in Schließstellung der Teile eingreift und sicherstellt, daß die Enden der Bügel und der diesen zugeordneten Aufreihstifte sich nicht nennenswert gegeneinander verlagern können. Hierbei sichert jedoch eine Hebelmechanik für das Öffnen und das Schließen der Bügel dagegen, daß sich die Enden der Teile voneinander hinwegbewegen können, wie das aufgrund der Federwirkung des Mechanikdeckels bei Ringbuchmechaniken gattungsgemäßer Art der Fall sein kann.In a lifting ball mechanism (DE-A-563 549), the stirrups for opening a pivoting movement prior to pivoting have an end pin which engages in a bore in the upper end of alignment pins in the closed position of the parts and ensures that the ends of the stirrups and of the alignment pins assigned to them cannot significantly shift against each other. Here, however, a lever mechanism for opening and closing the bracket ensures that the ends of the parts can move away from each other, as can be the case due to the spring action of the mechanical cover in ring binder mechanisms of the generic type.

Der Erfindung liegt die Aufgabe zugrunde, eine Ringbuchmechanik der im Oberbegriff des Anspruchs 1 genannten Art zu schaffen, bei der die Ringteile in ihrer Schließstellung auch bei hohen Belastungen durch Schriftgut zuverlässig allseitig justiert und gegen Auflösung des Ringschlusses durch Verlagerung der Ringteileenden gesichert sind.The invention has for its object to provide a ring binder mechanism of the type mentioned in the preamble of claim 1, in which the ring parts are reliably adjusted on all sides in their closed position even under high loads from documents and are secured against dissolution of the ring closure by displacement of the ring part ends.

Diese Aufgabe löst die Erfindung bei einer Ringbuchmechanik nach dem Oberbegriff des Anspruchs 1 mit den Merkmalen des kennzeichnenden Teils des Anspruchs 1. Hinsichtlich weiterer Ausgestaltungen wird auf die Ansprüche 2 und 3 verwiesen.This object is achieved by the invention in a ring binder mechanism according to the preamble of claim 1 with the features of the characterizing part of claim 1. With regard to further refinements, reference is made to claims 2 and 3.

Die erfindungsgemäße Ringmechanik sichert mit einfachen Mitteln eine Eintrittszentrierung, eine Schließstellungszentrierung und den Ausschluß nennenswerter Querverlagerungen der Enden zueinander, die ein Öffnen der Ringteile unter starken Belastungen zur Folgen haben könnten.The ring mechanism according to the invention ensures, by simple means, an entry centering, a closed position centering and the exclusion of any significant transverse displacements of the ends from one another which could result in the ring parts being opened under heavy loads.

Ein Ausführungsbeispiel des Gegenstands der Erfindung ist in der Zeichnung näher veranschaulicht. In der Zeichnung zeigen:

  • Fig. 2 u. 3 abgebrochene, perspektivische Ansichten der Enden der Ringteile eines Ringteilepaares, und
  • Fig. 4 u. 5 abgebrochene Seitenansichten der Ringteile eines Ringteilepaares, bereichsweise im Schnitt.
An embodiment of the object of the invention is illustrated in more detail in the drawing. The drawing shows:
  • 1 is an overall perspective view of a ring binder mechanism according to the invention,
  • Fig. 2 u. 3 broken perspective views of the ends of the ring parts of a pair of ring parts, and
  • Fig. 4 u. 5 broken side views of the ring parts of a ring part pair, partially in section.

Die Ringbuchmechanik besteht im einzelnen aus einem federnden Mechanikdeckel 1, der im Bereich seiner Enden für eine Vernietung mit einer buchförmigen Einbanddecke vorbereitet ist. Der Mechanikdeckel 1 überdeckt und umgreift zwei gegenläufig kippgelenkig verbundene Ringschienen- oder -schlangenteile, die im Mechanikdeckel 1 federnd abgestützt sind und Ringteile 2, 3 tragen. Dieanden nicht dargestellten Ringschienenoder schlangenteilen befestigten Ringteile 2, 3 bilden jeweils paarweise gemeinsam Ringe für die Aufnahme von gelochtem Schriftgut. Die Ringteile 2, 3 bestehen aus gezogenem oder gewalztem Metalldraht unrunden, z.B. ovalförmigen Querschnitts, wie dies insbesondere den Fig. 4 und 5 entnommen werden kann. Die Ringteile 2, 3 haben an ihren freien Enden ebene Stirnflächen 4, 5, die in Schließstellung der Ringteile 2, 3 bündig aneinanderliegen. Der Ringteil 2 weist an seinem Ende eine zumindest in ihrem Hauptteil zylindrische, senkrecht in die Stirnfläche 4 eingesenkte Bohrung 6 auf, und der Ringteil 3 ist an seinem Ende mit einem zumindest in seinem Hauptteil zylindrischen, von der Stirnfläche 5 senkrecht vorstehenden Zapfen 7 versehen.The ring binder mechanism consists in detail of a resilient mechanical cover 1, which is prepared in the area of its ends for riveting with a book-shaped cover. The mechanical cover 1 covers and encompasses two ring rail or snake parts which are connected in opposite directions and which are resiliently supported in the mechanical cover 1 and carry ring parts 2, 3. The ring rails 2, 3, which are not shown, are attached to the ring rails or snake parts and form pairs of rings for receiving perforated documents. The ring parts 2, 3 consist of drawn or rolled metal wire out of round, e.g. oval cross-section, as can be seen in particular FIGS. 4 and 5. The ring parts 2, 3 have flat end faces 4, 5 at their free ends, which lie flush against one another in the closed position of the ring parts 2, 3. The ring part 2 has at its end a bore 6, at least in its main part, which is countersunk vertically into the end face 4, and the ring part 3 is provided at its end with a pin 7, which at least in its main part is cylindrical and projects vertically from the end face 5.

Zwischen dem zylindrischen Teil der Bohrung 6 und dem zylindrischen Teil des Zapfens 7 ist ein Passungsspiel vorhanden, das gegenläufige Kippbewegungen zum Öffnen bzw. Schließen der Ringteile 2, 3 ermöglicht. Um ein behinderungsfreies Eindringen des Zapfens 7 in die Bohrung 6 bei einer Schließbewegung der Ringteile zu sichern, ist der Zapfen 7 an seinem Vorderende mit einer rundumlaufenden Fase 8 von etwa 45 bis 60° versehen.There is a clearance between the cylindrical part of the bore 6 and the cylindrical part of the pin 7, which allows counter-rotating movements to open or close the ring parts 2, 3. In order to ensure an unimpeded penetration of the pin 7 into the bore 6 during a closing movement of the ring parts, the pin 7 is provided at its front end with an all-round chamfer 8 of approximately 45 to 60 °.

Die zylindrische Bohrung 6 mündet mit einer rundumlaufenden Fase 9 von etwa 45° in die sie umgebende Stirnfläche 4 ein. Diese Fase 9 begünstigt ihrerseits das Eindringen des Zapfens 7 in die Bohrung 6 bei Schießbewegungen der Ringteile 2, 3, hat jedoch insbesondere die Aufgabe, mit einer umlaufenden, konischen Erweiterung 10 zusammenzuwirken, mit der der Zapfen 7 in die Stirnfläche 5 seines Ringteils 3 übergeht. Der Konuswinkel der Erweiterung beträgt ebenfalls etwa 45°, so daß in Schließstellung Fase 9 und Erweiterung 10 in formschlüssigem Eingriff stehen. Dadurch werden Verlagerungsmöglichkeiten quer zur Ebene der von den Ringteilen 2, 3 gebildeten Ringe vermieden, die aufgrund des Passungsspiels auftreten könnten. Bei Drukeinwirkung quer zur Ebene der Ringteile 2, 3 kann zwar durch die Keilwirkung zwischen den Bereichen 9, 10 eine geringfügige Bewegung im Öffnungssinne erfolgen, jedoch ist in jedem Falle sichergestellt, daß die zylindrischen Bereiche von Zapfen 7 und Bohrung 6 in gegenseitigem Eingriff verbleiben und weitere Verlagerungen verhindern.The cylindrical bore 6 opens into the end face 4 surrounding it with an all-round chamfer 9 of approximately 45 °. This chamfer 9 in turn favors the penetration of the pin 7 in the bore 6 during shooting movements of the ring parts 2, 3, however, has in particular the task of interacting with a circumferential, conical extension 10 with which the pin 7 merges into the end face 5 of its ring part 3. The cone angle of the extension is also approximately 45 °, so that chamfer 9 and extension 10 are in positive engagement in the closed position. This avoids displacement possibilities across the plane of the rings formed by the ring parts 2, 3, which could occur due to the clearance. When pressure is applied transversely to the plane of the ring parts 2, 3, the wedge action between the areas 9, 10 allows a slight movement in the opening direction, but it is ensured in any case that the cylindrical areas of the pin 7 and the bore 6 remain in mutual engagement and prevent further relocations.
