Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele beschrieben,
wobei auf eine Zeichnung Bezug genommen ist, in der
Fig. 1 und 2 zeigen in Seitenansicht eine erste Ausführungsform eines erfindungsgemäßen
Papierlochers in schematischer Weise. Ein Unterteil 1 trägt seitliche Lagerböcke
2, auf denen um eine Schwenkachse 3 ein Betätigungshebel 4 schwenkbar gehalten
ist und auf nicht dargestellte, lediglich durch ihre Längsmittelachse 5 angedeutete
Lochstempel gegen die Rückstellkraft von ebenfalls nicht dargestellten Federn
wirkt.1 and 2 show a side view of a first embodiment of an inventive
Paper punches in a schematic way. A
Wie Fig. 5 perspektivisch zeigt, sind die Lagerböcke 2 durch seitliche, abgewinkelte
Bereiche eines einstückig als Blechteil ausgebildeten Lagerbockteils 6 gebildet, welches
in entsprechende Aufnahmeschlitze des Unterteils einzusetzen ist. Lagerlaschen
8 dienen zur Aufnahme der Schwenkachse 3, während abgewinkelte Führungslaschen
10 sowie ein Querelement 12 zur Führung der Druckstempel dienen.5 shows in perspective, the
Fig. 3 und 4 zeigen perspektivisch eine aus einem Betätigungshebel 4, dem Lagerbockteil
6 und der Schwenkachse 3 zusammengesetzte Einheit in Ausgangs- und
Betätigungsstellung. Der Betätigungshebel 4 ist, wie das Lagerbockteil 6, als abgekantetes
und geprägtes Blechteil hergestellt, wobei zwei abgewinkelte Lagerlappen
16 die Lagerböcke 2 bzw. deren Lagerlaschen 8 seitlich übergreifen und zusammen
mit der Schwenkachse 3 die Schwenklagerung für den Betätigungshebel bilden.3 and 4 show in perspective one of an
Wie Fig. 1 bis 5 zeigen, sind an den Lagerböcken 2 Ausprägungen 18 gebildet, die in
Fig. 6 in vergrößertem Maßstab im Horizontalschnitt (parallel zur Ebene des Unterteils
1) dargestellt sind. Die Ausprägungen 18 sind ausgehend von einer geraden
Stanzlinie, die senkrecht zur Ebene des Unterteils verläuft und in Fig. 5 und 6 mit 20
bezeichnet ist, annähernd viertelkugelförmig in Richtung zur jeweiligen Außenseite
der Lagerböcke 2 ausgeprägt und bilden eine parallel zur Stanzlinie 20 verlaufende,
ebene erste Anschlagfläche 22 auf der Außenseite der Lagerböcke 2. Die runde bzw.
im wesentlichen viertelkugelartige Außenfläche der Ausprägung 18 bildet eine weitere
erste Anschlagfläche 24 auf der Außenseite der Lagerböcke 2.As shown in FIGS. 1 to 5, two
Zweite Anschlagflächen 26 und 28 sind durch entsprechende Ausnehmungen bzw.
einen entsprechenden Konturverlauf des unteren, im montierten Zustand zum Unterteil
1 weisenden Randes der Lagerlappen 16 des Betätigungshebels 4 ausgebildet,
wobei die zweite, geradlinig verlaufende Anschlagfläche 26 mit der ersten Anschlagfläche
22 zusammenwirkt und gemeinsam mit dieser einen Anschlag in Rückstellrichtung
bildet, wodurch die Ruhestellung festgelegt ist (Fig. 1), und die weitere
zweite Anschlagfläche 28 mit der weiteren ersten Anschlagfläche 24 zusammenwirkt
und gemeinsam mit dieser einen Anschlag in Betätigungsrichtung bildet, durch den
die maximal niedergedrückte Stellung des Betätigungshebels festgelegt ist (Fig. 2).
Obwohl grundsätzlich ein einziger Anschlag auf einer Seite des Lochers, d.h. auf nur
einem der beiden Lagerböcke 2 und einem der Lagerlappen 16, ausreichen würde,
sind zweckmäßigerweise sämtliche Anschläge bzw. Anschlagflächen auf beiden
Seiten des Lochers vorgesehen. Although basically a single stop on one side of the punch, i.e. on only
one of the two bearing
Während der durch die Anschlagflächen 22 und 26 gebildete Anschlag in Rückstellrichtung
zur Festlegung der Ruhestellung wesentlich ist, ist der durch die Anschlagflächen
24 und 28 gebildete Anschlag, der der Festlegung der maximal niedergedrückten
Stellung dient, nicht unbedingt erforderlich und könnte entfallen.During the stop formed by the
Wie in Fig. 1 und 2 angedeutet ist, weist der Betätigungshebel 4 eine aufgerastete
Abdeckung 30 auf, die insbesondere aus Kunststoff besteht und zwei seitlich heruntergezogene,
die Anschlagflächen 22 bis 28 (und die Ausprägung 18)verdeckende
Seitenwangen 32 aufweist. Die Abdeckung 30 kann ferner eine vordere, quer zwischen
den Seitenwangen 32 verlaufende Schürze 34 aufweisen, die zur optischen
Abdeckung der dahinterliegenden Locherelemente dient.As indicated in FIGS. 1 and 2, the
Fig. 7 und 8 zeigen eine alternative Ausführungsform der Erfindung, die sich von der
ersten Ausführungsform im wesentlichen dadurch unterscheidet, daß die ersten Anschlagflächen
22 und 24 nicht in Form einer Ausnehmung bzw. als Kontur des unteren
Rands der Lagerlappen des Betätigungshebels ausgebildet sind, sondern jeweils
durch eine nach außen geprägte Vertiefung 36 der seitlichen Lagerlappen 16 des
Betätigungshebels 4 gebildet sind. Durch die nach außen gerichtete Prägung weist
der Bereich der Vertiefung 36 einen größeren seitlichen Abstand zur Außenfläche
des benachbarten Lagerbocks 2 auf, so daß die die ersten Anschlagflächen 22, 24
bildende Ausprägung 18 in dem so gebildeten Zwischenraum zwischen der Innenfläche
der Vertiefung 36 und der Außenfläche des Lagerbocks 2 liegt. Der eine zweite
Anschlagfläche 26 bildende Abschnitt des Rands der Vertiefung 36 ist hierbei durch
eine gerade Stanzlinie vorgegeben, während die übrigen Randbereiche und insbesondere
der die zweite Anschlagfläche 28 bildende Randbereich eine stufen- bzw. im
wesentlichen z-förmige, durch den Prägevorgang gebildete Querschnittsform aufweisen. 7 and 8 show an alternative embodiment of the invention, which is different from the
differs first embodiment essentially in that the
Der Bereich der Vertiefung 36 weist somit einen größeren seitlichen Abstand zur
Außenfläche des benachbarten Lagerbocks 2 auf als der übrige Teil des Lagerlappens
16, so daß die Vertiefung 36 die Ausprägung 18 seitlich übergreift und in jeder Betätigungsstellung
eine unfallsichere Abdeckung nach außen (Fig. 7 und 8) bildet, ohne
