A ring mechanism, the mechanism cover (1) of which is provided with rivet holes (2, 3) at the ends, with at least one further opening (13) disposed in the region between the rivet holes, and a cup-shaped rivet insertion (12) disposed in the further opening, characterised in that the rivet insertion (12) is captively connected to the mechanism cover (1).

Description

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

Bei Ringmechaniken dieser Art dient der Nieteinsatz dazu, den Abstand zwischen der Ebene der den Nieteinsatz aufnehmenden öffnung des Mechanikdeckels und der Befestigungsebene für den Mechanikdeckel zu überbrücken und auch an dieser Stelle eine Vernietung mit einem Niet zu ermöglichen, wie er auch an den Nietstellen an den Enden des Mechanikdeckels Verwendung findet. Vernietungen im mittleren Bereich zusätzlich zu den endseitigen Vernietungen des Mechanikdeckels sind bei Ringmechaniken erwünscht, die sehr lang oder dazu bestimmt sind, besonders viel oder schweres Aufreihgut aufzunehmen.In ring mechanisms of this type, the rivet insert is used to bridge the distance between the plane of the opening of the mechanical cover receiving the rivet insert and the fastening plane for the mechanical cover and also to enable riveting at this point, as is also the case at the rivet points on the Ends of the mechanical cover is used. Rivets in the central region to the end of the riveting mechanism cover are also desirable in ring mechanics that are very long or intended, particularly much or heavy A ufreihgut take.

Bei einer bekannten Ringmechanik dieser Art ist der Nieteinsatz ein Teil, das gesondert geliefert und erst beim Einnieten der Ringmechanik in das Ringbuch mit dem Mechanikdeckel vereinigt wird. Hierzu wird der Nieteinsatz auf den zugehörigen Nietstempel einer,Nietmaschine aufgesetzt, wonach dann die Ringmechanik auf die Nietstempel der Maschine aufgesetzt, das Ringbuch aufgelegt und in einem gemeinsamen Arbeitsvorgang schließlich sämtliche Niete angebracht werden.In a known ring mechanism of this type, the rivet insert is a part that is supplied separately and is only combined with the mechanical cover when the ring mechanism is riveted into the ring binder. For this purpose, the rivet insert is placed on the associated riveting ram of a riveting machine, after which the ring mechanism is then placed on the riveting ram of the machine, the ring binder is placed, and finally all rivets are attached in a joint operation.

Das Vorhandensein eines zusätzlichen, von der Ringmechanik unabhängigen Teils und die bei dem Befestigen der Ringmechanik dadurch notwendig werdenden Handarbeitsgänge komplizieren die Herstellung von Ringbüchern mit derartigen Mechaniken und verursachen entsprechend hohe Kosten.The presence of an additional part, which is independent of the ring mechanism, and the manual operations that are necessary when fastening the ring mechanism complicate the production of ring binders with such mechanisms and cause correspondingly high costs.

Der Erfindung liegt die Aufgabe zugrunde, eine Ringmechanik der eingangs genannten Art zu schaffen, die eine einfache, schnelle und gegebenenfalls vollautomatische Handhabung der Teile beim Nietvorgang ermöglicht.The invention has for its object to provide a ring mechanism of the type mentioned, which enables simple, fast and possibly fully automatic handling of the parts during the riveting process.

Zur Lösung dieser Aufgabe sieht die Erfindung in erster Linie die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale vor. Hinsichtlich wesentlicher weiterer Ausgestaltungen wird auf die Ansprüche 2 bis 11 verwiesen.To achieve this object, the invention primarily provides the features specified in the characterizing part of claim 1. With regard to essential further refinements, reference is made to claims 2 to 11.

Die erfindungsgemäße Ausgestaltung der Ringmechanik ordnet den Nieteinsatz dem Mechanikdeckel als unverlierbaren Bestandteil zu mit der Folge, daß die Ringmechanik eine einheitliche handhabbare Baugruppe beim Nietvorgang darstellt, der nunmehr vollautomatisch durch Nietvollautomaten ausführbar ist. In jedem Falle verringern und vereinfachen sich die bis zur Fertigstellung des Ringbuches auszuführenden Handarbeitsgänge, wodurch der Verbindungsvorgang beschleunigt und verbilligt wird. Dies gilt auch für die Handhabung zu Lagerungs- und Transportzwecken.The design of the ring mechanism according to the invention assigns the rivet insert to the mechanical cover as a captive component, with the result that the ring mechanism represents a uniform, manageable assembly during the riveting process, which can now be carried out fully automatically by fully automatic riveting machines. In any case, the manual work steps to be carried out until the completion of the ring binder are reduced and simplified, as a result of which the connecting process is accelerated and cheaper. This also applies to handling for storage and transport purposes.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich' aus der nachfolgenden Beschreibung und der Zeichnung, in der ein Ausführungsbeispiel des Gegenstands der Erfindung näher veranschaulicht ist. Im einzelnen zeigen:

  • Fig. 1 eine perspektivische Gesamtansicht einer Ringmechanik nach der Erfindung,
  • Fig. 2 einen schematischen Längsmittelschnitt durch die Ringmechanik nach Fig. 1,
  • Fig. 3 eine Ausschnittvergrößerung des den Nieteinsatz einschließenden Schnittbereichs der Ringmechanik nach Fig. 2, und
  • Fig. 4 eine Ansicht eines Nieteinsatzes von unten, teilweise im Schnitt.
Further details and advantages of the invention will become apparent from the following description and the drawing, in which an embodiment of the object of the invention is illustrated in more detail. In detail show:
  • 1 is an overall perspective view of a ring mechanism according to the invention,
  • 2 shows a schematic longitudinal central section through the ring mechanism according to FIG. 1,
  • 3 shows an enlarged detail of the cutting area of the ring mechanism according to FIG. 2, including the rivet insert, and
  • Fig. 4 is a view of a rivet insert from below, partly in section.

Wie die Fig. 1 und 2 erkennen lassen, besteht die Ringmechanik aus einem federelastischen Mechanikdeckel 1, der an seinen Enden in flachgedrückten Bereichen mit Nietlöchern 2,3 versehen ist, und aus paarweise an nicht näher veranschaulichten Ringschlangen- bzw. -schienenteilen befestigten Ringteilen 4,5, die.jeweils gemeinsam einen Ring 6 zur Aufnahme von gelochtem Schriftgut bilden und aus ihrer dargestellten Schließlage durch Auseinanderklappen in eine Offenstellung überführbar sind. Zur Verbindung der Ringmechanik, dem Rücken- oder einem Deckelteil eines Ringbuches 7 dienen Niete 8,9,10, von denen die ersteren die Nietlöcher 2,3 und der letztgenannte ein Nietloch 11 in einem topfförmigen Nieteinsatz 12 durchgreifen. Dieser Nieteinsatz 12 ist in einer im Bereich zwischen den Nietlöchern 2,3 angeordneten, bei dem dargestellten Beispiel mittig vorgesehenen öffnung 13 im Mechanikdeckel angeordnet. Die öffnung 13 ist von einem eingesenkten Randbereich 14 umgeben, und der Nieteinsatz 12 weist einen oberen, nach außen umgebogenen Randflansch 15 auf, der den Randbereich 14 der öffnung 13 oberseitig übergreift.As can be seen in FIGS. 1 and 2, the ring mechanism consists of a spring-elastic mechanical cover 1, which is provided with rivet holes 2, 3 at its ends in flattened areas, and of ring parts 4 fastened in pairs to ring snake or rail parts, which are not illustrated in detail , 5, which, each together, form a ring 6 for receiving perforated documents and can be converted from their illustrated closed position into an open position by unfolding them. To connect the ring mechanism, the back or a cover part of a ring binder 7, rivets 8, 9, 10 are used, of which the former reach through the rivet holes 2, 3 and the latter a rivet hole 11 in a cup-shaped rivet insert 12. This rivet insert 12 is arranged in an opening 13 in the area between the rivet holes 2, 3, which is provided centrally in the example shown, in the mechanical cover. The opening 13 is surrounded by a countersunk edge area 14, and the rivet insert 12 has an upper, outwardly bent edge flange 15 which overlaps the edge area 14 of the opening 13 on the upper side.

Die Seitenwand 16 des Nieteinsatzes 12 ist im wesentlichen zylindrisch und geht unterseitig in einen einwärts umgebogenen, das Nietloch 11 umgebenden Boden 17 über.The side wall 16 of the rivet insert 12 is essentially cylindrical and merges on the underside into an inwardly bent bottom 17 surrounding the rivet hole 11.

Der Nieteinsatz 12 ist mit dem Mechanikdeckel 1 unverlierbar verbunden. Hierzu sieht das dargestellte Ausführungsbeispiel vor, daß der Nieteinsatz 12 unterhalb der Ebene der öffnung 13 zumindest bereichsweise eine Querschnittsabmessung aufweist, die größer ist als der Durchmesser der öffnung 13. Dieser Bereich oder diese Bereiche vergrößerter Querschnittsabmessung können von einem oder mehreren, z.B. drei, Vorsprüngen gebildet sein, die wie dargestellt als nockenförmige Ausprägung 18, oder als Ringwulst, oder auch als Zungen 19 ausgebildet sein können, die aus der Seitenwand 16 des Nieteinsatzes 12 durch Ausstanzen und Ausbiegen gebildet sind. Die Ausbildung des oder der Vorsprünge als Ausprägung ist besonders einfach. Sie werden mit Hilfe eines Spreizwerkzeuges gebildet, nachdem der Nieteinsatz in die öffnung 13 des Mechanikdeckels 1 eingesetzt ist. Dies gilt auch für einen Vorsprung in Gestalt einer Ringwulst, die jedoch auch durch einen Stauchvorgang gebildet werden kann.The rivet insert 12 is captively connected to the mechanical cover 1. For this purpose, the exemplary embodiment shown provides that the rivet insert 12, at least in regions, has a cross-sectional dimension below the plane of the opening 13 that is larger than the diameter of the opening 13. This region or these regions of enlarged cross-sectional dimension can have one or more, for example three, projections be formed, which can be formed as shown as a cam-shaped configuration 18, or as an annular bead, or also as tongues 19, which are formed from the side wall 16 of the rivet insert 12 by punching and bending. The formation of the protrusion or protrusions is particularly simple. They are formed with the help of a spreading tool after the Rivet insert is inserted into the opening 13 of the mechanical cover 1. This also applies to a projection in the form of an annular bead, which, however, can also be formed by an upsetting process.

Eine Ausgestaltung des oder der Vorsprünge als Riegelzunge eröffnet die Möglichkeit einer Festlegung des Nieteinsatzes 12 in der öffnung 13 des Mechanikdeckels 1 durch eine Schnappverriegelung beim Einsetzen. Vorsprünge vorbeschriebener oder sonst geeigneter Ausbildung haben den Vorteil, daß zwischen der Seitenwand 16 des Nieteinsatzes und der öffnung 13 im Mechanikdeckel 1 ein Ringspalt 20 vorgesehen werden kann, durch den der Nieteinsatz 12 zwar unverlierbar, jedoch begrenzt beweglich im Mechanikdeckel gehalten ist. Dies erlaubt einen einfachen Toleranzausgleich.An embodiment of the protrusion (s) as a locking tongue opens up the possibility of fixing the rivet insert 12 in the opening 13 of the mechanical cover 1 by means of a snap lock when it is inserted. Protrusions of the above-described or other suitable design have the advantage that an annular gap 20 can be provided between the side wall 16 of the rivet insert and the opening 13 in the mechanical cover 1, through which the rivet insert 12 is held captive but has limited movement in the mechanical cover. This allows easy tolerance compensation.

In Fällen, in denen auf einen solchen Toleranzausgleich verzichtet werden kann, besteht auch die Möglichkeit zu einer von dem dargestellten Ausführungsbeispiel abweichenden Ausgestaltung der unverlierbaren Verbindung des Nieteinsatzes 12 mit dem Mechanikdeckel 1. So kann z.B. der Nieteinsatz 12 durch Klemmung in der öffnung 13 im Mechanikdeckel festgelegt werden, was durch entsprechende Bemessung der öffnung 13 und Seitenwand 16 des Nieteinsatzes 12 zumindest in Höhe der öffnung 13 und Einpressen des Nieteinsatzes 12 in den Mechanikdeckel herbeigeführt werden kann. Denkbar ist auch eine Festlegung durch Verkleben der Teile 14,15 an ihren in eingesetzter Stellung des Nieteinsatzes 12 in gegenseitigem Eingriff befindlichen Flächen.In cases in which such tolerance compensation can be dispensed with, there is also the possibility of a configuration of the captive connection of the rivet insert 12 with the mechanical cover 1 which differs from the exemplary embodiment shown. the rivet insert 12 can be fixed by clamping in the opening 13 in the mechanical cover, which can be brought about by appropriate dimensioning of the opening 13 and side wall 16 of the rivet insert 12 at least at the level of the opening 13 and pressing the rivet insert 12 into the mechanical cover. It is also conceivable to fix the parts 14, 15 to their surfaces in mutual engagement when the rivet insert 12 is in the inserted position.

Eine weitere Ausgestaltung, die auch bei Belassung eines Ringspaltes 20 ausführbar ist, besteht in einem Aufschieben eines Klemmringes von der Bodenseite des Nieteinsatzes 12 her nach dessen Einsetzen in die öffnung 13 des Mechanikdeckels 1. Auch ein auf dem Boden 17 nach dem Einsetzen des Nieteinsatzes 12 aufgeklebter, über die Seitenwand 16 vorstehender Aufkleber könnte als zusätzliches Sicherungsmittel die unverlierbare Festlegung gewährleisten.A further embodiment, which can also be carried out when an annular gap 20 is left, consists in pushing on a clamping ring from the bottom side of the rivet insert 12 after inserting it into the opening 13 of the mechanical cover 1. Also on the bottom 17 after inserting the rivet insert 12 glued on, protruding over the side wall 16 sticker could ensure the captive fixation as an additional securing means.

Bei allen vorbeschriebenen Ausgestaltungen ist der Nieteinsatz 12 unverlierbarer Bestandteil des Mechanikdeckels und damit der Ringmechanik als Baugruppe, die somit ohne weiteres einfach mit dem Ringbuch 7 vernietbar ist, insbesondere auch durch Nietvollautomaten.In all of the configurations described above, the rivet insert 12 is a captive component of the mechanical cover and thus the ring mechanism as an assembly, which is thus easily riveted to the ring binder 7, in particular also by fully automatic rivets.
