Description

Die Erfindung bezieht sich auf eine Verschlußmechanik für eine Halteeinrichtung für gelochte lose Blätter mit auf einer Grundplatte befestigten festen Dornen und an der Grundplatte schwenkbar gehaltenen und mit einander verbundenen, beweglichen und eine Krummung aufweisenden Dornen, die an den festen Dornen zur Anlage bringbar sind, wobei die beweglichen Dorne über eine Lagerplatte miteinander verbunden sind, die in der Grundplatte mittels aus dieser ausgebogener und Durchbrüche der Lagerplatte mit geringem Spiel durchsetzender Lappen, die um eine gemeinsame, parallel zur Verbindungslinie der Befestigungspunkte der beweglichen Dorne an der Lagerplatte verlaufende Achse aufgebogen sind, schwenkbar gelagert ist.The invention relates to a locking mechanism for a holding device for perforated loose sheets with fixed thorns attached to a base plate and pivotally held on the base plate and connected to each other, movable and having a curvature thorns, which can be brought into contact with the fixed thorns, wherein the movable mandrels are connected to one another by means of a bearing plate which can be pivoted in the base plate by means of tabs which are bent out of this and pass through the openings in the bearing plate with little play and which are bent around a common axis running parallel to the connecting line of the fastening points of the movable mandrels on the bearing plate is stored.

Eine solche Verschlußmechanik wurde z.B. durch die DE-PS 816 689 bekannt. Bei dieser ist eine, abgesehen von einem ausgebogenen Lappen zur Aufnahme der Lagerung eines Betätigungshebels der Verschlußmechanik und zweier kleiner Lappen zur Halterung der Lagerplatte, glatte Grundplatte vorgesehen. Dabei sind die beweglichen Dorne in einer ebenfalls im wesentlichen glatten Lagerplatte gehalten, die mit zwei Schlitzen versehen ist, die von den beiden kleinen Lappen der Grundplatte durchsetzt sind. Zur Sicherung der Verbindung der Lagerplatte mit der Grundplatte, sind die die Lagerplatte durchsetzenden Lappen oberhalb derselben abgebogen.Such a locking mechanism has been e.g. known from DE-PS 816 689. In this case, apart from a bent-out tab for receiving the mounting of an actuating lever of the locking mechanism and two small tabs for holding the bearing plate, a smooth base plate is provided. The movable mandrels are held in an essentially smooth bearing plate, which is provided with two slots which are penetrated by the two small tabs of the base plate. To secure the connection of the bearing plate to the base plate, the tabs passing through the bearing plate are bent above the same.

Dadurch ergibt sich aber eine nur relativ geringe Sicherheit gegen ein Lösen dieser Verbindung. Außerdem behindern die abgebogenen Lappen die Schwenkbarkeit der Lagerplatte, insbesondere, wenn diese zur Erhöhung der Sicherheit der Verbindung der Lagerplatte mit der Grundplatte um einen Winkel in der Größenordnung von 90° abgebogen sind und nur ein geringes Spiel zwischen der Lagerplatte und derInnenseite der abgebogenen Lappen verbleibt. Es ergibt sich daher, daß die Sicherheit der Verbindung der beiden Platten mit einer Einschränkung deren gegenseitiger Beweglichkeit erkauft werden muß, was dazu führt, daß bei der Fertigung sehr enge Toleranzen vorgesehen werden müssen, die nur schwer eingehalten werden können. Dabei ist auch noch zu berücksichtigen, daß in den Lappen, die ja aus der Grundplatte vorher ausgestanzt und aus dieser herausgebogen worden sind, aufgrund dieser Bearbeitungen Spannungen auftreten können, die die Einhaltung dieser engen Toleranzen weiter erschweren.However, this results in only relatively low security against loosening this connection. In addition, the bent tabs hinder the pivoting of the bearing plate, in particular if they are bent by an angle of the order of 90 ° to increase the security of the connection of the bearing plate to the base plate and only a slight play remains between the bearing plate and the inside of the bent tabs . It follows, therefore, that the security of the connection of the two plates has to be bought with a restriction of their mutual mobility, which leads to the fact that very tight tolerances have to be provided during production which are difficult to maintain. It should also be taken into account that in the rag, yes have previously been punched out of the base plate and bent out of it, because of these machining operations, tensions can occur which further complicate compliance with these narrow tolerances.

Ziel der Erfindung ist es diese Nachteile zu vermeiden und eine Verschlußmechanik der eingangs erwähnten Art vorzuschlagen, bei der trotz einem hohen Maß an Sicherheit der Verbindung der beiden Platten gegen ein unbeabsichtigtes Lösen einhohes Maß an Beweglichkeit der beiden Platten gegeneinander gegeben ist.The aim of the invention is to avoid these disadvantages and to propose a locking mechanism of the type mentioned in the introduction, in which, despite a high degree of security of the connection of the two plates against unintentional loosening, a high degree of mobility of the two plates is provided with respect to one another.

Erfindungsgemäß wird dies dadurch erreicht, daß die Grundplatte eine Versteifungsrippe aufweist, die parallel zur Biegeachse der aus der Grundplatte aufgebogenen Lappen verläuft und die Lagerplatte an ihrer der Versteifungsrippe der Bodenplatte zugekehrten Stirnseite aus dieser vorragende Vorsprünge aufweist, die in Durchbrechungen mit geringem Spiel eingreifen, die in der der Stirnseite der Lagerplatte zugekehrten Seitenwand der Versteifungsrippe angeordnet sind.According to the invention this is achieved in that the base plate has a stiffening rib which runs parallel to the bending axis of the flaps bent out of the base plate and the bearing plate on its end face facing the stiffening rib of the base plate has protruding projections therefrom which engage in openings with little play which are arranged in the side wall of the stiffening rib facing the end face of the bearing plate.

Auf diese Weise läßt sich mit sehr einfachen Mitteln eine leicht schwenkbare Halterung der Lagerplatte an der Grundplatte bei einer sehr sicheren Verbindung der beiden Platten erzielen. Dabei läßt sich diese Halterung durch einfaches Ausstanzen der Lappen aus der Grundplatte herstellen, wobei dies in einem gemeinsamen Arbeitsgang mit dem Ausstanzen der Grundplatte selbst erfolgen kann. Dabei sorgen die Lappen in Verbindung mit den Vorsprüngen gleichzeitig für eine entsprechende Festlegung der Position der Lagerplatte sowohl in Richtung der Kippachse der Lagerplatte wie auch senkrecht zu dieser, wodurch auch das Aufeinandertreffen der Stirnseiten der beweglichen Dorne mit jenen der feststehenden Dorne sichergestellt wird. Durch die einander kreuzenden Lappen und Vorsprünge und die Ausbildung der Verstärkungsrippe an der Grundplatte ergibt sich eine sehr sichere Festlegung der Lagerplatte an der Grundplatte, wobei die Verschiebbarkeit der Lagerplatte in Richtung quer zur durch die aus der Grundplatte ausgebogenen Lappen bestimmten Schwenkachse der Lagerplatte aufgrund der Verstärkungsrippe sehr klein gehalten werden kann. Dies ermöglicht es auch, die aus der Grundplatte aufragenden Lappen oberhalb der Lagerplatte nur wenig abzubiegen, wobei auch durchaus größere Toleranzen zugelassen werden können, und trotzdem ein sehr hohes Maß an Sicherheit gegen ein unabsichtliches Lösen der Verbindung zwischen der Grund- und der Lagerplatte zu erzielen.In this way, an easily pivotable mounting of the bearing plate on the base plate with a very secure connection of the two plates can be achieved with very simple means. This bracket can be produced by simply punching out the tabs from the base plate, which can be done in a common operation with punching out the base plate itself. The tabs in conjunction with the projections simultaneously ensure a corresponding fixing of the position of the bearing plate both in the direction of the tilting axis of the bearing plate and perpendicularly to the latter, which also ensures that the end faces of the movable mandrels meet those of the fixed mandrels. The intersecting tabs and projections and the formation of the reinforcing rib on the base plate result in a very secure fixing of the bearing plate to the base plate, the displaceability of the bearing plate in the direction transverse to the pivot axis of the bearing plate determined by the tabs bent out of the base plate due to the reinforcing rib can be kept very small. This also makes it possible to bend the tabs protruding from the base plate only slightly above the bearing plate, whereby larger tolerances can also be permitted, and still achieve a very high degree of security against unintentional loosening of the connection between the base plate and the bearing plate.

Außerdem erlaubt auch die Anordnung einer Versteifungsrippe die Verwendung dünnerer Bleche, ohne daß dadurch die Festigkeit und Steifigkeit der Verschlußmechanik leidet. Gleichzeitig wird durch die Versteifungsrippe auch ein entsprechender Anschlag für die Lagerplatte geschaffen, wodurch mit der sehr einfach gestalteten Lagerung das Auslangen gefunden werden kann.In addition, the arrangement of a stiffening rib allows the use of thinner sheets without the strength and rigidity of the locking mechanism being impaired. At the same time, the stiffening rib also creates a corresponding stop for the bearing plate, which means that the very simple storage can be used.

Durch die erfindungsgemäß vorgesehene Ausbildung der Lagerung der Lagerplatte wird durch die Anordnung der Lappen eine Art Verzahnung der Lagerplatte mit der Grundplatte erreicht, durch die ein Verrutschen der Lagerplatte beim Abbiegen der Lappen nach dem Aufsetzen der Lagerplatte auf diese sicher verhindert wird, wodurch ein nennenswerter Ausschußanfall auch bei einer vollautomatischen Montage der Verschlußmechanik mit konventionellen Einrichtungen verhindert wird.Due to the design of the mounting of the bearing plate provided according to the invention, a kind of interlocking of the bearing plate with the base plate is achieved by the arrangement of the tabs, by means of which the bearing plate is prevented from slipping when the tabs are bent after the bearing plate has been placed on it, thereby causing a notable amount of rejects is prevented even with a fully automatic assembly of the locking mechanism with conventional devices.

Bei einer besonders bevorzugten Ausführungsform der Erfindung kann vorgeshen sein, daß die Lagerplatte in ihrem Mittelbereich eine in deren Ebene liegende, vorzugsweise trapezförmige Ausformung aufweist und die sich im wesentlichen in Richtung der Verbindungslinie der Befestigungspunkte der beweglichen Dorne verlaufenden Kanten zweier quer zu dieser aneinander gereihter Lagerplatten gegengleich verlaufen.In a particularly preferred embodiment of the invention it can be provided that the bearing plate in its central region has a preferably trapezoidal shape lying in the plane thereof and the edges of two edges of the bearing mandrels arranged transversely to this and running essentially in the direction of the connecting line of the fastening points of the movable mandrels run in opposite directions.

Dies ermöglicht es bei der Herstellung der Grundplatten den Anfall von Abfall beim Ausstanzen praktisch vollständig zu vermeiden. Gleichzeitig wird durch die Ausformung der Lagerplatte auch erreicht daß diese relativ schmal gehalten werden kann und trotzdem ein ausreichender Hebelarm für eine an dieser Ausformung angreifenden, die beweglichen Dorne im Sinne des Öffnens der Verschlußmechanik beaufschlagenden Feder geschaffen wird.This makes it possible to practically completely avoid the generation of waste when punching out the base plates. At the same time, the shape of the bearing plate also ensures that it can be kept relatively narrow, and yet a sufficient lever arm is created for a spring that engages this shape and acts on the movable mandrels in the sense of opening the locking mechanism.

Weiters kann vorgesehen sein, daß die Lagerplatte eine im Querschnitt im wesentlichen trapezförmige Versteifungsrippe aufweist, in deren Steg die beweglichen Dorne eingesetzt sind.Furthermore, it can be provided that the bearing plate has a stiffening rib which is essentially trapezoidal in cross section and in whose web the movable mandrels are inserted.

Auf diese Weise wird durch die Versteifungsrippe, die eine Verminderung der Materialstärke der Lagerplatte ermöglicht, gleichzeitig Platz für die Vernietung der beweglichen Dorne mit der Lagerplatte geschaffen.In this way, the stiffening rib, which enables a reduction in the material thickness of the bearing plate, also creates space for riveting the movable mandrels to the bearing plate.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 eine Draufsicht auf die erfindungsgemäße Verschlußmechanik, wobei die Dorne geschnitten dargestellt sind und
  • Fig. 2 eine teilweise im Schnitt dargestellte Seitenansicht dieser Verschlußmechanik.
The invention will now be explained in more detail with reference to the drawing. Show:
  • Fig. 1 is a plan view of the locking mechanism according to the invention, the mandrels are shown in section and
  • Fig. 2 is a partially sectioned side view of this locking mechanism.

Die Verschlußmechanik weist eine Grundplatte 1 auf, in der die festen Dorne 2 gehalten sind. Weiters ist auf der Grundplatte 1 eine Lagerplatte 3 schwenkbar gehalten, in der die beweglichen Dorne 4 gehalten sind.The locking mechanism has a base plate 1, in which the fixed mandrels 2 are held. Furthermore, a bearing plate 3 is pivotally held on the base plate 1, in which the movable mandrels 4 are held.

Die Grundplatte 1 ist mit einer Versteifungsrippe 5 versehen, die sich über den größten Teil der Grundplatte erstreckt, aber den Bereich der Bohrungen 6′, die zur Aufnahme von Befestigungselementen, wie z.B. Nieten vorgesehen sind, und den Bereich der Lagerplatte 3 freiläßt. Dabei ist die Lagerplatte 3 zwischen der Versteifungsrippe 5 und einer weiteren entlang der Kante der Grundplatte verlaufenden weiteren Versteifungsrippe 5′ eingebettet.The base plate 1 is provided with a stiffening rib 5 which extends over most of the base plate, but the area of the bores 6 'which are used to hold fasteners, such as e.g. Rivets are provided and leaves the area of the bearing plate 3 free. The bearing plate 3 is embedded between the stiffening rib 5 and another along the edge of the base plate further stiffening rib 5 '.

Wie insbesondere aus der Fig. 2 zu ersehen ist, weist die Lagerplatte 3 an ihrer der Versteifungsrippe 5′ zugekehrten Stirnseite Vorsprünge 6 auf, die an der der Lagerplatte 3 zugekehrten Stirnwand der Versteifungsrippe 5′ angeordnete Durchbrüche 7 durchsetzen und den Steg der Versteifungsrippe 5′ untergreifen. Dabei sind die Abmessungen der Vorsprünge einerseits und der Durchbruche 7 anderseits so bemessen, daß sich nur ein geringes Spiel zwischen diesen Teilen ergibt.As can be seen in particular from Fig. 2, the bearing plate 3 has on its the stiffening rib 5 'facing end projections 6, which on the bearing plate 3 facing end wall of the stiffening rib 5' arranged openings 7 'and the web of the stiffening rib 5' reach under. The dimensions of the projections on the one hand and the openings 7 on the other hand are dimensioned such that there is only a slight play between these parts.

Für die Lagerung der Lagerplatte 3 sind aus der Grundplatte 1 Lappen 8 augestanzt und nach oben aufgebogen. Diese Lappen 8 durchsetzen Durchbrüche 9 der Lagerplatte 3, wobei der Überstand der Lappen 8 nach dem Aufsetzen der Lagerplatte 3 in Richtung zur Versteifungsrippe 5′ hin abgebogen wird, wodurch ein späteres Abheben der Lagerplatte 3 verhindert und eine einwandfreie Lagerung der Lagerplatte 3 sichergestellt wird.For the storage of the bearing plate 3 1 tab 8 are punched out and bent upwards. These tabs 8 pass through openings 9 of the bearing plate 3, the projection of the tabs 8 after the bearing plate 3 is bent in the direction of the stiffening rib 5 ', whereby a later lifting of the bearing plate 3 is prevented and proper storage of the bearing plate 3 is ensured.

Die Lagerplatte 3 weist gleichfalls eine Versteifungsrippe 10 auf deren Stegbereich von den beweglichen Dornen 4 durchsetzt sind. Durch diese Maßnahme wird neben einer Aussteifung der Lagerplatte 3 auch Platz für die Ausbildung der Nietköpfe der Dorne 4 an der Unterseite der Lagerplatte 3 geschaffen. Gleiches gilt auch bezüglich der festen Dorne 2 die ebenfalls im Bereich der Versteifungsrippe 5 in der Grundplatte gehalten und mittels einer Nietung mit dieser verbunden sind.The bearing plate 3 likewise has a stiffening rib 10 on the web area of which the movable mandrels 4 pass. In addition to stiffening the bearing plate 3, this measure also creates space for the formation of the rivet heads of the mandrels 4 on the underside of the bearing plate 3. The same also applies to the fixed mandrels 2, which are likewise held in the base plate in the area of the stiffening rib 5 and are connected to the base plate by means of a rivet.

Aus der Grundplatte 1 ist in üblicher Weise ein Haltelappen 11 ausgestanzt und aufgebogen, der zur Aufnahme der Lagerung des Schließhebels 12 dient, der mit seiner Rolle 13 an der erhabenen Versteifungsrippe 10 der Lagerplatte 3 anliegt und diese in der Schließstellung der Verschlußmechanik entgegen der Kraft der in der Grundplatte 1 gehaltenen und an der Unterseite der Lagerplatte 3 anliegenden Feder 14 geschlossen hält. Dabei ergeben sich für die Feder 14 aufgrund der trapezförmigen Ausformung 15, in deren Bereich die Feder an der Lagerplatte 3 angreift, ein relativ gute Hebelverhältnisse, obwohl die Lagerplatte 3 relativ schmal ist.From the base plate 1, a retaining tab 11 is punched out and bent open, which serves to accommodate the mounting of the locking lever 12, which rests with its roller 13 on the raised stiffening rib 10 of the mounting plate 3 and this in the closed position of the locking mechanism against the force of the held in the base plate 1 and on the underside of the bearing plate 3 spring 14 keeps closed. This results in a relatively good leverage for the spring 14 due to the trapezoidal shape 15, in the area of which the spring engages the bearing plate 3, although the bearing plate 3 is relatively narrow.

Um beim Ausstanzen der Lagerplatte 3 einen Verschnitt zu vermeiden verlaufen die Kanten der Lagerplatte 3 zu beiden Seiten der durch die Durchbrüche 9 bestimmten Lagerachse gegengleich. So entsprechen die Ausnehmungen 16 an der einen Kante genau den Vorsprüngen 6 an der anderen Kante. Desgleichen sind die Längen der beiden parallel zu der einen Kante der Grundplatte verlaufenden Kanten der Lagerplatte 3 im Bereich deren Ausformung 15 gleich lang, wie überhaupt die Längen der einzelnen Abschnitte der zu beiden Seiten der Versteifungsrippe 10 verlaufenden Kanten der Lagerplatte 3 gleich lang sind, sodaß die Lagerplatten 3 Stoß auf Stoß in deren Ebene aneinandergereiht werden können, ohne, daß sich dabei freie Stellen ergeben. Dies ermöglicht eine besonders gute Ausnutzung des eingesetzten Rohmaterials.In order to avoid a waste when punching out the bearing plate 3, the edges of the bearing plate 3 run in opposite directions on both sides of the bearing axis determined by the openings 9. The recesses 16 on one edge correspond exactly to the projections 6 on the other edge. Likewise, the lengths of the two edges of the bearing plate 3 running parallel to the one edge of the base plate in the region of their shape 15 are the same length, as are the lengths of the individual sections of the edges of the bearing plate 3 running on both sides of the stiffening rib 10, so that they are the same length the bearing plates 3 can be strung together in their plane, without there being any vacancies. This enables particularly good utilization of the raw material used.
