Beschreibungdescription
Die Erfindung betrifft ein Heftklammergerät mit einem Bodenteil, mit einem im rückwärtigen Bereich des Boden¬ teils um eine Querachse begrenzt verschwenkbaren Klam¬ mermagazin mit einem um die Querachse gegenüber dem Klammermagazin und dem Bodenteil begrenzt verschwenkba¬ ren, eine Kappe tragenden oder als Kappe ausgebildeten Oberteil, mit einer in einer Halterung des Oberteils pendelnd gelagerten, in einen Ausstoßkanal des Klammer¬ magazins einführbaren, durch Verschwenken des Oberteils in Ausstoßrichtung verschiebbaren Treiberplatte und mit einer am Klammermagazin oder an einer im Oberteil be¬ findlichen Magazinabdeckung angeordneten, durch ein parallel zur Verschieberichtung ausgerichtetes Langloch der Treiberplatte von hinten nach vorn hindurchgreifen¬ den und unter der Einwirkung einer zwischen Oberteil und Klammermagazin bzw. Magazinabdeckung angeordneten Feder gegen die untere Begrenzungskante des Langlochs anschlagbaren, mit ihrem freien Ende über die vordere Breitseitenflache der Treiberplatte überstehenden An¬ schlagnase.The invention relates to a stapler with a base part, with a clip magazine which can be pivoted to a limited extent about a transverse axis in the rear region of the base part, with a clip part which can be pivoted about the transverse axis with respect to the clip magazine and the base part and which carries a cap or is designed as a cap , with a pendulum mounted in a holder of the upper part, which can be inserted into an ejection channel of the staple magazine, can be displaced by swiveling the upper part in the ejection direction, and with a magazine cover arranged on the staple magazine or on a magazine cover located in the upper part, by a parallel to the direction of movement Grip the slot of the driver plate from the back to the front and, under the action of a spring arranged between the upper part and the clip magazine or magazine cover, can be struck against the lower boundary edge of the slot with its free end over the front pulp Stop nose protruding from the side of the driver plate.

schwenkbar ist und eine unter der Einwirkung einer Fe¬ der begrenzt um die Querachse verschwenkbare, in der Schließstellung des Oberteils in das Klammermagazin von oben her eingreifende, die Anschlagnase tragende Maga¬ zinabdeckung aufweist. Beim Öffnen des Oberteils wird die Magazinabdeckung über ihre an der Treiberplatte eingehängte Anschlagnase vom Klammermagazin abgehoben und in die Ladestellung mitgenommen. Wenn die Magazin¬ abdeckung in dieser Stellung entgegen der Kraft der Feder gegenüber dem Oberteil verschwenkt wird, hebt sich die Anschlagnase von der Langlochunterkante der Treiberplatte ab. Dabei entsteht die Gefahr, daß die Treiberplatte um ihre Pendelachse aus dem Wirkungsbe¬ reich der Anschlagnase herausgeschwenkt wird und sich von der Magazinabdeckung löst, mit dem Ergebnis, daß das Heftgerät funktionsunfähig wird. Um dies zu vermei¬ den, wurde bereits vorgeschlagen, die Anschlagnase als das Langloch an ihrem Unterrand und an ihren Seitenrän¬ dern übergreifende Rastnase auszubilden. Jedoch auch hierbei sind Fehlbedienungen, die zu einer teilweisen Demontage der Treiberplatte, der Magazinabdeckung und der mit dieser zusammenwirkenden Feder führen können, nicht ausgeschlossen.is pivotable and has a magazine cover which can be pivoted under the action of a spring to a limited extent about the transverse axis and which engages in the clamp magazine from above in the closed position of the upper part and carries the stop lug. When the upper part is opened, the magazine cover is lifted off the clip magazine via its stop lug, which is attached to the driver plate, and taken into the loading position. If the magazine cover is pivoted in this position against the force of the spring relative to the upper part, the stop lug rises from the lower edge of the elongated hole in the driver plate. This creates the danger that the driver plate is pivoted about its pendulum axis out of the effective range of the stop lug and detaches from the magazine cover, with the result that the stapler becomes inoperable. In order to avoid this, it has already been proposed to design the stop lug as the elongated hole on its lower edge and overlapping lug on its side edges. However, incorrect operation, which can lead to partial disassembly of the driver plate, the magazine cover and the spring interacting with it, cannot be ruled out here either.
Bei Heftklammergeräten mit Springfachmechanik weist das Klammermagazin eine Schubführung für einen federunter- εtützten Klammerschieber und ein parallel zum Klammer¬ schieber verschiebbares und am Klammermagazin einrast- bares, an seiner Stirnseite den Ausstoßkanal aufweisen¬ des Springfach für die Heftklammern auf.

Bei geschlossenem Springfach wird die in den Ausstoßka¬ nal eingreifende Unterkante der Treiberplatte von der Springfachoberkante umfaßt. Diese Umfassung fehlt bei geöffnetem Springfach, so daß bei unsachgemäßer Handha¬ bung die Gefahr besteht, daß sich die Treiberplatte aus dem Eingriff der Anschlagnase löst. Je nach Kon¬ struktion kann die Treiberplatte dabei aus ihrer Halte- rung herausfallen und verlorengehen. Außerdem wird hier¬ bei die federunterstützte Verbindung zwischen Klammer¬ magazin und Oberteil getrennt, so daß das Heftklammer¬ gerät insgesamt nicht mehr funktionsfähig ist. Sofern nicht zusätzliche Vorkehrungen getroffen sind, kann dabei auch eine im Bereich zwischen Klammermagazin und Oberteil lose angeordnete Feder verlorengehen.nose is rigidly connected to the clip magazine or a magazine cover rigidly connected to it. When the spring compartment is closed, the lower edge of the driver plate engaging in the ejection channel is encompassed by the upper edge of the spring compartment. This enclosure is missing when the spring compartment is open, so that if it is handled improperly there is a risk that the driver plate will come loose from the engagement of the stop lug. Depending on the design, the driver plate can fall out of its holder and be lost. In addition, the spring-assisted connection between the staple magazine and the upper part is separated, so that the staple device as a whole is no longer functional. Unless additional precautions are taken, a spring loosely arranged in the area between the clip magazine and the upper part can also be lost.
Ausgehend hiervon liegt der Erfindung die Aufgabe zu¬ grunde, die bekannten Heftklammergeräte mit Oberlader- oder Springfachmechanik dahingehend zu verbessern, daß ein ungewolltes Lösen der Verbindung zwischen Klammer¬ magazin bzw. Magazinabdeckung, Oberteil und Treiber¬ platte mit einfachen Mitteln verhindert wird.Proceeding from this, the invention is based on the object of improving the known stapling devices with top loading or jumping compartment mechanics in such a way that an unintentional loosening of the connection between the staple magazine or magazine cover, upper part and driver plate is prevented with simple means.
Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To achieve this object, the combination of features specified in claim 1 is proposed. Further advantageous refinements and developments of the invention result from the dependent claims.
Die Erfindung geht von dem Gedanken aus, daß ein ver- 1251The invention is based on the idea that a different 1251

sehentliches Lösen der Treiberplatte aus ihrer Einbau¬ lage dadurch verhindert werden kann, daß die Kappe eine mit ihrer Unterkante bis in die Nähe der Anschlagnase reichende oder diese stirnseitig übergreifende Stirn¬ wand aufweist, die an ihrer der Anschlagnase zugewand¬ ten Innenfläche mit mindestens einem in der Nähe ihrer Unterkante in seitlichem Abstand von der Anschlagnase angeordneten, zur vorderen Breitseitenfläche der Trei¬ berplatte weisenden Vorsprung versehen ist. Der Abstand zwischen den nach einander entgegengesetzten Seiten weisenden freien Enden des Vorsprungs und der Anschlag¬ nase sollte dabei kleiner als die Materialstärke der Treiberplatte gewählt werden. Besser ist es, wenn der Vorsprung und die Anschlagnase sich im Bereich ihrer freien Enden seitlich überlappen. Mit diesen Maßnahmen wird erreicht, daß zwischen der Anschlagnase einerseits und dem Vorsprung der Kappen-Stirnwand andererseits kein Zwischenraum freibleibt, durch den die Treiber¬ platte hindurchpaßt.Visible detachment of the driver plate from its installation position can be prevented by the cap having an end wall that extends with its lower edge into the vicinity of the stop lug or overlaps the end face, which has at least one in on its inner surface facing the stop lug the vicinity of its lower edge at a lateral distance from the stop lug, facing the front broad side surface of the driver plate, is provided. The distance between the free ends of the projection facing one another and the stop lug should be chosen to be smaller than the material thickness of the driver plate. It is better if the projection and the stop lug laterally overlap in the area of their free ends. With these measures it is achieved that between the stop lug on the one hand and the projection of the cap end wall on the other hand no space remains free, through which the driver plate fits.
Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Kappe zwei in seitlichem Abstand voneinander auf einander entgegengesetzten Seiten der Anschlagnase angeordnete Vorsprünge aufweist.A preferred embodiment of the invention provides that the cap has two projections arranged at a lateral distance from one another on opposite sides of the stop lug.
