Description

Der Gegenstand vorliegender Erfindung geht aus von einer Verschlußmechanik für Ordner gemäß dem Oberbegriff des Patentanspruches 1 (DE-C 350 736).The object of the present invention is based on a locking mechanism for files according to the preamble of claim 1 (DE-C 350 736).

Den vorbekannten Mechaniken der betreffenden Art haftete gemeinsam der Nachteil an, daß sie entweder kostspielig und unhandlich waren oder aber Konstruktionen betrafen, bei denen der vergleichsweise lange und an seinem Ende zur Erleichterung der Bedienung aufgebogene Schwenkbügel bei geöffneter Mechanik von außen gegen einen der beweglichen Dorne anstieß oder sich im Raume zwischen den freien Enden einerseits der beweglichen und anderseits der festen Dorne befand. Diese Stellung des Schwenkbügels verunmöglichte es, bei offener Mechanik Blätter von einem Stapel in den anderen umzulegen, ohne jeweils die Mechanik zu schließen, d.h. den Schwenkbügel aus der erwähnten Stellung zu entfernen.The previously known mechanics of the type in question had the disadvantage that they were either expensive and unwieldy or concerned constructions in which the comparatively long swivel bracket, which was bent at the end to facilitate operation, bumped against one of the movable mandrels from the outside when the mechanics were open or was in the space between the free ends of the movable and on the other hand the fixed mandrels. This position of the swivel bracket made it possible to move sheets from one stack to the other with the mechanism open, without closing the mechanism, i.e. remove the swivel bracket from the position mentioned.

Der vorliegenden Erfindung lag nun die Aufgabe zugrunde, eine Verschlußmechanik der eingangs genannten Art zu schaffen, welche kostengünstig hergestellt werden kann, handlich ist und es zudem gestattet, den Vorteil des an sich zweckmäßigen, langen und infolgedessen leicht zu bedienenden Schwenkbügels beizubehalten und trotzdem bei offener Verschlußmechanik z.B. durch die festen Dorne gehaltene Blätter in die beweglichen Dorne umzulegen, ohne, wie dies bis dahin notwendig war, die Verschlußmechanik jeweils zu schließen und auf diese Weise den Schwenkbügel in eine Stellung zu bringen, in welcher er das Umlegen der Blätter nicht behinderte.The present invention was based on the object to provide a locking mechanism of the type mentioned, which can be manufactured inexpensively, is handy and also allows to maintain the advantage of the practical, long and consequently easy to use swivel bracket and still open Lock mechanism e.g. to move the sheets held by the fixed mandrels into the movable mandrels without, as was previously necessary, closing the locking mechanism and in this way bringing the swivel bracket into a position in which it did not hinder the turning of the sheets.

Bei einer bevorzugten Ausführungsform ist es dazuhin noch möglich, den Schwenkbügel in einer sich vor der Endstellung befindlichen Zwischenlage zu halten.In a preferred embodiment, it is also possible to keep the swivel bracket in an intermediate position before the end position.

Die erwähnte allgemeine Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruches 1 erwähnten Merkmale gelöst.The general task mentioned is solved by the features mentioned in the characterizing part of claim 1.

In der Zeichnung sind zwei beispielsweise Ausführungsformen des Erfindungsgegenstandes dargestellt, und zwar zeigen: Fig. 1 eine erste Ausführungsform perspektivisch in geschlossener Stellung, Fig. 2 die gleiche Ausführungsform in einer Seitenansicht in einer Zwischenstellung, Fig. 3 die gleiche Ausführungsform in einer Seitenansicht in der Endstellung, Fig. 4 eine Einzelheit der zweiten Ausführungsform in Ansicht von vorne und Fig. 5 einen Schnitt nach der Linie V-V in Fig. 4.The drawing shows two exemplary embodiments of the subject matter of the invention, namely: FIG. 1 shows a first embodiment in perspective in the closed position, FIG. 2 shows the same embodiment in a side view in an intermediate position, FIG. 3 shows the same embodiment in a side view in FIG 4, a detail of the second embodiment in a view from the front, and FIG. 5, a section along the line VV in FIG. 4.

Die in der Zeichnung dargestellte Verschlußmechanik für Ordner ist dazu bestimmt, mit der Bodenplatte 1 auf der Innenseite des Rückens eines Ordners befestigt zu werden. Ein Ordner dient bekanntlich dazu, gelochte Blätter aufzunehmen, wobei der Abstand der Löcher dem Abstand der beiden festen Dome 2 und der beiden beweglichen Dorne 3 entspricht. Dabei wird jeweils die Verschlußmechanik geöffnet, das Blatt mit seinen beiden Löchern über die festen Dorne 2 gelegt und anschließend durch entsprechende Bewegung der beweglichen Dorne 3 die Mechanik wieder geschlossen. Beim ersten, in den Fig. 1-3 dargestellten Ausführungsbeispiel ist eine auf der Bodenplatte 1 befestigte und rechtwinklig von ihr abstehende Lagerplatte 4 vorgesehen, in welcher die Schwenkachse 5 für den Schwenkbügel 6 befestigt ist. Der Schwenkpunkt des Schwenkbügels 6 ist mit 7 bezeichnet. Der Schwenkbügel 6 besitzt eine solche Länge, daß er auf der einen Seite über die Bodenplatte 1 hinausragt und in der in Fig. 1 dargestellten, geschlossenen Stellung durch den durch einen festen Dorn 2 und einen beweglichen Dorn 3 gebildeten Umlegebügel 2/3 durchtritt. An seinem Ende ist der Schwenkbügel 6 nach oben abgebogen und mit einem nach außen abstehenden Bedienungsfortsatz 8 versehen. Durch diese Ausbildung des Schwenkbügels 6 wird es ermöglicht, die Verschlußmechanik auf einfachste Weise zu öffnen, indem die hiezu notwendigen Betätigungsmittel (Ende des Schwenkbügels 6 mit Bedienungsfortsatz 8) aus dem durch die vier Dorne 2 und 3 begrenzten Raum hinaustreten und deshalb gut zugänglich sind.The locking mechanism for folders shown in the drawing is intended to be attached to the base plate 1 on the inside of the back of a folder. As is known, a folder serves to hold perforated sheets, the distance between the holes corresponding to the distance between the two fixed domes 2 and the two movable mandrels 3. The locking mechanism is opened in each case, the sheet with its two holes is placed over the fixed mandrels 2 and then the mechanism is closed again by appropriate movement of the movable mandrels 3. In the first exemplary embodiment shown in FIGS. 1-3, a bearing plate 4 is attached to the base plate 1 and projects at a right angle from it, in which the pivot axis 5 for the pivot bracket 6 is fastened. The pivot point of the swivel bracket 6 is designated 7. The swivel bracket 6 has such a length that it projects on one side beyond the base plate 1 and in the closed position shown in FIG. 1 passes through the folding bracket 2/3 formed by a fixed mandrel 2 and a movable mandrel 3. At its end, the swivel bracket 6 is bent upward and provided with an operating extension 8 protruding outwards. This design of the swivel bracket 6 makes it possible to open the locking mechanism in the simplest way by the necessary actuating means (end of the swivel bracket 6 with the operating extension 8) coming out of the space delimited by the four mandrels 2 and 3 and therefore being easily accessible.

Der Schwenkbügel 6 besitzt zwischen seinem Schwenkpunkt 7 und dem Betätigungsfortsatz 8 eine Abkröpfung 9 sowie einen über den Schwenkpunkt 7 hinausreichenden, zur Abkröpfung 9 angenähert rechtwinklig angeordneten Fortsatz 10. Im Abkröpfungspunkt 11 sowie am Ende des Fortsatzes 10 ist jeweils eine Achse 12 befestigt, auf welcher je eine verschiebbare Kunststoffrolle 13a bzw. 13b gehalten ist. Dabei ist die gegenseitige Anordnung der Rollen 13 und des Schwenkpunktes 7 derart gewählt, daß in der in Fig. 1 dargestellten, geschlossenen Stellung der Verschlußmechanik eine parallel zur Lagerplatte 4 gerichtete und auf die Rolle 13a einwirkende Kraft ein Moment im Uhrzeigersinn auf den Schwenkbügel 6 ausübt. Der Betätigungsbügel 14 besitzt einen doppelt abgewinkelten Wirkteil 14a, mit welchem er in den Bereich der Rollen 13a und 13b reicht, wobei er in der in Fig. 1 dargestellten, geschlossenen Stellung der Mechanik von der Feder 15 gegen die Rolle 13a angedrückt wird. Ebenso besteht der Betätigungsbügel 14 aus einem Stück mit den beweglichen Dornen 3 und ist an den Lagerstellen 16 auf der Bodenplatte 1 schwenkbar gehalten.Between its pivot point 7 and the actuating extension 8, the swivel bracket 6 has an offset 9 and an extension 10 extending beyond the pivot point 7 and approximately at right angles to the offset 9. In the offset point 11 and at the end of the extension 10, an axis 12 is fastened, on which one slidable plastic roller 13a or 13b is held. The mutual arrangement of the rollers 13 and the pivot point 7 is chosen such that in the closed position of the locking mechanism shown in FIG. 1, a force directed parallel to the bearing plate 4 and acting on the roller 13a exerts a moment in a clockwise direction on the pivot bracket 6 . The actuating bracket 14 has a double-angled active part 14a, with which it extends into the area of the rollers 13a and 13b, wherein it is pressed against the roller 13a by the spring 15 in the closed position of the mechanism shown in FIG. 1. Likewise, the actuating bracket 14 consists of one piece with the movable mandrels 3 and is pivotally held at the bearing points 16 on the base plate 1.

Es bestünde natürlich auch die Möglichkeit, zwei vom Betätigungsbügel 14 getrennte Dorne 2 vorzusehen, in welchem Falle diese Dorne 2 mit dem Betätigungsbügel 14 verbunden wären.There would of course also be the possibility of providing two mandrels 2 separated from the actuating bracket 14, in which case these mandrels 2 would be connected to the actuating bracket 14.

Dabei sind die Abmessungen so gewählt, daß in der in Fig. 1 dargestellten, geschlossenen Stellung die vom Betätigungsbügel 14 auf die Rolle 13a ausgeübte Kraft auf der dem freien Ende des Schwenkbügels 6 abgewendeten Seite der Schwenkachse 5 verläuft, so daß auf diesen ein in Fig. 1 im Uhrzeigersinn gerichtetes Moment ausgeübt wird, was zur Folge hat, daß er gegen die Bodenplatte 1 oder sonst einen Teil der Mechanik anschlägt, in welcher Stellung, zum Zwecke der Bildung einer durchgehenden Umlegebahn für die gelochten Blätter, die freien Enden der beweglichen Bügel 3 auf die freien Enden der festen Bügel 2 auftreffen.The dimensions are chosen so that, in the closed position shown in FIG. 1, the force exerted by the actuating bracket 14 on the roller 13a runs on the side of the pivot axis 5 facing away from the free end of the pivot bracket 6, so that a pivot shown in FIG 1 clockwise torque is exerted, with the result that it strikes against the base plate 1 or some other part of the mechanism, in which position, for the purpose of forming a continuous flap for the perforated sheets, the free ends of the movable brackets 3 hit the free ends of the fixed brackets 2.

Wird nun von der geschlossenen Stellung gemäß Fig. 1 der Schwenkbügel 6 im Gegenuhrzeigersinn so weit verschwenkt, bis die vom Betätigungsbügel 14 nunmehr auf die Rolle 13a ausgeübte Kraft auf der dem Schwenkbügel 6 zugewendeten Seite der Schwenkachse 5 verläuft, so verdreht sich der Schwenkbügel 6 unter der Wirkung des Betätigungsbügels 14 bis zum Erreichen einer Zwischenlage, wie sie in Fig. 2 dargestellt ist.1 of the swivel bracket 6 is pivoted counterclockwise until the force exerted by the actuating bracket 14 on the roller 13a on the side of the swivel bracket 6 facing Swiveling axis 5 extends, the swivel bracket 6 rotates under the action of the actuating bracket 14 until an intermediate position is reached, as shown in FIG. 2.

In dieser Zwischenlage, in welcher die Verschlußmechanik um ein bestimmtes Maß geöffnet ist, steht die Rolle 13b gegen den Betätigungsbügel 14 an, wodurch, ebenso wie durch die Stellung der Rolle 13a, diese Zwischenlage bestimmt ist.In this intermediate position, in which the locking mechanism is opened to a certain extent, the roller 13b is in contact with the actuating bracket 14, which, as well as the position of the roller 13a, determines this intermediate position.

Wird nun, von dieser Zwischenlage ausgehend, der Schwenkbügel 6 weiter im Gegenuhrzeigersinn soweit verschwenkt, bis auch die auf die Rolle 13b ausgeübte Federkraft des Betätigungsbügels 14 in Fig. 1 rechts der Schwenkachse 5 verläuft, so kann der Schwenkbügel 6 in die in Fig. 1 gestrichelt und in Fig. 3 in Seitenansicht dargestellte Endlage überführt werden, in welcher die Verschlußmechanik derart geöffnet ist, daß das ungehinderte Um- oder Einlegen der gelochten Blätter gewährleistet ist.If, starting from this intermediate position, the swivel bracket 6 is pivoted further counterclockwise until the spring force of the actuating bracket 14 exerted on the roller 13b also extends to the right of the swivel axis 5 in FIG. 1, the swivel bracket 6 can be moved into the position shown in FIG. 1 dashed and transferred in Fig. 3 in side view end position, in which the locking mechanism is opened such that the unimpeded turning or inserting the perforated sheets is ensured.

Dadurch wird erreicht, daß Blätter von dem in den beweglichen Dornen 3 gehaltenen Stapel oder von außen her ohne weiteres auf den in den festen Dornen 2 gehaltenen Stapel und umgekehrt um- bzw. eingelegt werden können, was immer dann nicht der Fall ist, wenn der Schwenkbügel 6 ganz oder teilweise in den Raum zwischen den freien Enden der beiden Dornenarten 2 und 3 bzw. ganz oder mit Teilen in den für eine ungehinderte Um- oder Einlegung notwendigen Raum hineinreicht. Dabei ist es wesentlich, daß diese vorteilhafte Wirkung unter Beibehaltung des die Bedienung der Verschlußmechanik entscheidend erleichternden, langen Schwenkbügels 6 mit seinem bei geschlossener Mechanik über den durch die Dornen 2 und 3 abgegrenzten Raum hinausragenden Bügelende samt Bedienungsfortsatz 8 möglich ist.It is thereby achieved that sheets from the stack held in the movable mandrels 3 or from the outside can be easily transferred to the stack held in the fixed mandrels 2 and vice versa, which is not always the case when the Swivel bracket 6 extends wholly or partially into the space between the free ends of the two types of thorns 2 and 3 or fully or partially into the space necessary for unimpeded transfer or insertion. It is essential that this advantageous effect is possible while maintaining the long pivoting bracket 6, which decisively facilitates the operation of the locking mechanism, with its closed end projecting beyond the space delimited by the mandrels 2 and 3, including the operating extension 8.

Das Ausführungsbeispiel gemäß den Fig. 4 und 5 unterscheidet sich von demjenigen gemäß Fig. 1-3 dadurch, daß der Anschlag zur Bestimmung der Zwischenstellung nicht durch eine Rolle, sondern durch einen Anschlag irgendwelcher Art, z.B. durch einen federnden Stift oder Bolzen 17, gebildet wird, der in die Bahn des Schwenkbügels 6 hineinragt und gegebenenfalls zur Erleichterung seiner Bewegung durch den Schwenkbügel 6 eine nicht dargestellte schiefe Fläche aufweisen kann, so daß seine Verschiebung aus der Anschlagstellung bei einer Kraftwirkung auf den Schwenkbügel 6 erleichtert wird.The exemplary embodiment according to FIGS. 4 and 5 differs from that according to FIGS. 1-3 in that the stop for determining the intermediate position is not by a roller, but by a stop of some kind, e.g. is formed by a resilient pin or bolt 17 which protrudes into the path of the swivel bracket 6 and, if necessary, to facilitate its movement through the swivel bracket 6 may have an inclined surface, not shown, so that its displacement from the stop position when a force acts on the swivel bracket 6 is facilitated.

An der betreffenden Stelle wäre übrigens jede Ausbildung eines federnden Anschlages denkbar, beispielsweise auch eine solche, bei welcher der Schwenkbügel 6 eine Erhebung besitzen würde, welche in eine Raste der Lagerplatte 4 eintritt, wobei entweder besondere federnde Mittel vorgesehen werden können, oder aber die Federwirkung durch den Schwenkbügel 6 selbst erzeugt wird.At the point in question, any configuration of a resilient stop would be conceivable, for example also one in which the swivel bracket 6 would have an elevation which enters a catch of the bearing plate 4, wherein either special resilient means can be provided, or the spring action is generated by the swivel bracket 6 itself.

In einer weiteren nicht dargestellten Ausführungsform könnte der Schwenkbügel 6 anstatt wie beim Ausführungsbeispiel nach den Fig. 1 bis 3 eine Abkröpfung 9 und einen Fortsatz 12 aufweisen, mit einem flachen dreieckigen Kunststoffteil mit abgerundeten Ecken fest verbunden sein, der im Bereich einer Ecke an der Lagerplatte schwenkbar angelenkt ist und dessen beiden anderen abgerundeten Ecken anstelle der Rollen 13a,13b der Fig. 1 bis 3 als mit dem Betätigungsbügel 14 zusammenwirkende Anschläge dienen.In a further embodiment, not shown, the swivel bracket 6 could have an offset 9 and an extension 12 instead of, as in the exemplary embodiment according to FIGS. 1 to 3, with a flat triangular plastic part with rounded corners, which in the area of a corner on the bearing plate is pivotally articulated and its two other rounded corners serve instead of the rollers 13a, 13b of FIGS. 1 to 3 as stops cooperating with the actuating bracket 14.

Schließlich könnte der Schwenkbügel 6 zwar wie nach den Fig. 1 bis 3 eine Abkröpfung 9 aufweisen, in deren Bereich er an der Lagerplatte schwenkbar angelenkt ist, jedoch keinen Fortsatz 12. Dafür wäre dann im Bereich der Abkröpfung mit dem Schwenkbügel ein im wesentlichen flacher, länglicher Steuerteil, vorzugsweise aus Kunststoff, fest verbunden, dessen Enden abgerundet sind und die beiden mit dem Betätigungsbügel 14 zusammenwirkenden Anschläge bilden.Finally, the swivel bracket 6 could have an offset 9, as shown in FIGS. 1 to 3, in the area of which it is pivotably articulated on the bearing plate, but not an extension 12. In the area of the offset with the swivel bracket, an essentially flat, elongated control part, preferably made of plastic, firmly connected, the ends of which are rounded and form the two stops which cooperate with the actuating bracket 14.
