Locher mit verstellbaren LocheinheitenPunch with adjustable punching units
Beschreibungdescription
Die Erfindung betrifft einen Locher mit einem auf einer Unterlage aufstellbaren Unterteil, mindestens zwei am Unterteil in ihrem gegenseitigen Abstand verstellbar angeordneten, je eine Lochmatrize, einen Einschub¬ schlitz und einen Lochstempel aufweisenden Locheinhei¬ ten, einem am Unterteil schwenkbar gelagerten oder ver¬ schiebbar geführten, vorzugsweise als Druckhebel ausge¬ bildeten Druckorgan zum Verschieben der Lochstempel, und einer im Bereich vor den Einschubschlitzen der Loch¬ einheiten sich über die Einschublänge des Unterteils erstreckenden Skala für die Einstellung der Lochabstän¬ de zwischen den Locheinheiten.The invention relates to a perforator with a lower part that can be set up on a base, at least two perforated units that are adjustable on the lower part with respect to one another, each having a perforated die, an insertion slot and a punch, and a pivotally mounted or displaceably guided on the lower part , preferably designed as a pressure lever for moving the punch, and a scale in the area in front of the insertion slots of the perforating units, which extends over the insertion length of the lower part, for adjusting the spacing between the perforating units.
Mehrfachlocher mit verstellbaren Locheinheiten dieser Art sind üblicherweise mit feststehenden oder auswech¬ selbaren Skalen ausgerüstet. Größtenteils handelt es sich dabei um Millimeter- oder Zoll-Einteilungen, an¬ hand derer für verschiedene Ordner- oder Ringbucheinla¬ gen die Abstände zwischen den Locheinheiten errechnet werden müssen. Einfacher wäre es, wenn die Abstände für die verschiedenen Ringbuchtypen unmittelbar auf der Skala angegeben wären. Wegen der Vielzahl der in der Praxis vorkommenden Ringbuchtypen mit unterschiedlichen Lochabständen ist dies bei den herkömmlichen Mehrfach¬ lochern aus Gründen der Übersichtlichkeit der Markie¬ rungen aber nicht ohne weiteres möglich. Die bereits vorgeschlagene Auswechslung der Skalen führt anderer¬ seits zu unerwünschten Umrüstzeiten , ganz abgesehen davon, daß die augenblicklich nicht eingesetzten Skalen verlorengehen können.Multiple holes with adjustable hole units of this type are usually equipped with fixed or exchangeable scales. For the most part, these are millimeter or inch graduations, on the basis of which the distances between the perforated units have to be calculated for various file or ring binder inserts. It would be easier if the distances for the different ring bush types were given directly on the scale. Because of the large number of ring bush types that occur in practice with different hole spacing, this is not readily possible in the conventional multiple holes for reasons of clarity of the markings. On the other hand, the already proposed replacement of the scales leads to undesirable changeover times, quite apart from that from the fact that the scales not currently used can be lost.
Ausgehend hiervon liegt der Erfindung die Aufgabe zu¬ grunde, den Mehrfachlocher der eingangs angegebenen Art dahingehend zu verbessern, daß die Einstellung ver¬ schiedener Lochabstände zwischen den Locheinheiten durch eine übersichtliche Skalierung unterschiedlicher vorgegebener Lochraster vereinfacht wird.Proceeding from this, the invention is based on the object of improving the multiple hole punch of the type specified at the outset in such a way that the setting of different hole spacings between the hole units is simplified by a clear scaling of different predetermined hole patterns.
Die Erfindung geht von der Erkenntnis aus, daß ein Mehrfachlocher der genannten Art für eine Vielzahl un¬ terschiedlicher Lochabstände einsetzbar ist und daß es deshalb vorteilhaft ist, wenn die hierfür erforderli¬ chen Skalen übersichtlich und unverlierbar unmittelbar am Locher angeordnet sind. Um dies zu erreichen, wird gemäß der Erfindung vorgeschlagen, daß im Unterteil im Bereich vor den Eiπschubschlitzen der Locheinheiten ei¬ ne sich über die Einschublange des Unterteils erstrecken¬ de, nach oben randoffene langgestreckte Aussparung an¬ geordnet ist, und daß in der Aussparung ein sich um seine Längsachse drehbarer Skalenträger angeordnet ist, der mehrere, in verschiedenen Drehlagen nach oben wei¬ sende, durch die Randöffπung hindurch sichtbare Skalen trägt.The invention is based on the knowledge that a multiple hole punch of the type mentioned can be used for a large number of different hole spacings and that it is therefore advantageous if the scales required for this purpose are arranged directly and captively on the hole punch. In order to achieve this, it is proposed according to the invention that in the lower part in the area in front of the insertion slots of the hole units there is an elongated recess which is open at the top and extends over the insertion length of the lower part, and that there is a recess in the recess is arranged around its longitudinal axis rotatable scale carrier which carries a plurality of scales, which point upwards in different rotational positions and are visible through the edge opening.
Gemäß einer bevorzugten Ausgestaltung der Erfindung steht der Skalenträger mit seiner jeweils nach oben weisenden Skala über die Randöffnung des Unterteils über und kann in den den verschiedenen Skalen zugeord- neten vorgegebenen Drehstellungen am Unterteil arre¬ tiert oder eingerastet werden. Der Skalenträger hat vorteilhafterweise die Gestalt eines Rundstabs, kann jedoch auch als Mehrkantstab oder als Flachstab ausge¬ bildet sein.According to a preferred embodiment of the invention, the scale carrier with its upward-pointing scale projects beyond the edge opening of the lower part and can be assigned to the various scales. not specified or locked positions on the lower part. The scale carrier advantageously has the shape of a round bar, but can also be designed as a polygonal bar or as a flat bar.
Eine weitere vorteilhafte Ausgestaltung der Erfindung sieht vor, daß an den Enden des Skalenträgers achszen¬ tral überstehende Lagerzapfen angeordnet, vorzugsweise angeformt sind, die in drehfest mit dem Unterteil ver¬ bundene Zapfenlager eingreifen. Es ist dabei zweck¬ mäßig, mindestens eines der Zapfenlager als lösbar am Unterteil befestigbare, vorzugsweise einrastbare Lager¬ hülse auszubilden. Zwischen mindestens einem der Zap¬ fenlager und dem Skalenträger sind vorteilhafterweise federunterstützte Rastmittel zur Arretierung des Ska¬ lenträgers in den vorgegebenen Drehstellungen angeord¬ net. Zu diesem Zweck kann an der vorzugsweise aus Kunst¬ stoff bestehenden Lagerhülse eine biegeelastische Feder¬ zunge angeformt werden, die einen -in über den Umfang des Skalenträgers verteilt angeordnete Rastvertiefungen radial einrastenden Rastnocken aufweist. Um trotz der bestehenden Maßtoleranzen ein sicheres Einrasten zu ge¬ währleisten, werden die Rastvertiefungen vorteilhafter¬ weise in Achsrichtung des Skalenträgers langgestreckt ausgebildet .A further advantageous embodiment of the invention provides that axially central bearing journals are arranged, preferably integrally formed, at the ends of the scale carrier, which engage in journal bearings which are non-rotatably connected to the lower part. It is expedient to design at least one of the journal bearings as a bearing sleeve which can be detachably fastened to the lower part and is preferably snap-in. Spring-supported latching means for locking the scale carrier in the predetermined rotational positions are advantageously arranged between at least one of the journal bearings and the scale carrier. For this purpose, a flexible resilient tongue can be formed on the bearing sleeve, which is preferably made of plastic, and which has a latching cam which engages radially and is arranged in a manner distributed over the circumference of the scale carrier. In order to ensure a secure snap-in despite the existing dimensional tolerances, the snap-in depressions are advantageously elongated in the axial direction of the scale carrier.
Als Alternative hierzu können die Rastmittel durch eine in einer exzentrischen achsparallelen Aussparung des Zapfenlagers, vorzugsweise der Lagerhülse, angeordnete, federunterstützte Rastkugel sowie eine Anzahl über die dem betreffenden Zapfenlager zugewandte Stirnfläche des Skalenträgers im Radialabstand der Rastkugel umfangsver- teilt angeordnete Rastvertiefungen gebildet sein.As an alternative to this, the locking means can be arranged in an eccentric, axially parallel recess in the journal bearing, preferably the bearing sleeve. spring-supported detent ball and a number of detent recesses arranged circumferentially distributed over the end face of the scale carrier facing the relevant journal bearing can be formed in the radial spacing of the detent ball.
Um das Drehen des Skaleπträgers zu erleichtern, ist es von Vorteil, wenn einer der Lagerzapfen durch das zuge¬ hörige Zapfenlager, vorzugsweise durch die Lagerhülse hindurchgreift und an seinem über das Zapfenlager über¬ stehenden Teil einen mit dem Skalenträger drehfest ver¬ bundenen, vorzugsweise angeklebten Drehknopf trägt.In order to facilitate the rotation of the scale carrier, it is advantageous if one of the bearing journals extends through the associated journal bearing, preferably through the bearing sleeve and, on its part projecting beyond the journal bearing, has a preferably glued-on, glued to the scale carrier Wearing rotary knob.
Aus herstellungstechnischen Gründen besteht der Skalen¬ träger zweckmäßig aus längsgeteilten, einander spiegel¬ bildlich ergänzenden und miteinander verrast-und/oder verklebbaren Stabhälfteπ, wobei die Stabhälften zweck¬ mäßig als gleichgestaltete Spritzgußteile aus Kunst¬ stoff ausgebildet sind.For manufacturing reasons, the scale carrier expediently consists of longitudinally divided, mutually mirror-complementary rod halves that can be locked and / or glued to one another, the rod halves being expediently designed as identical injection-molded parts made of plastic.
Da die Papierformate trotz gleicher Lochabstände unter¬ schiedlich sein können, ist es von Vorteil, wenn am Un¬ terteil zusätzlich eine parallel zum Skalenträger längs¬ verschiebbar angeordnete und in verschiedenen Verschie¬ bestellungen einrastbare Anschlagschiene vorgesehen ist, die einen senkrecht über das Unterteil überstehen¬ den Anschlag für eine Seitenkante des zu lochenden Schriftguts aufweist.Since the paper formats can be different in spite of the same hole spacing, it is advantageous if an additional stop rail is provided on the lower part, which is longitudinally displaceable parallel to the scale carrier and can be snapped into place in different orders, which protrudes vertically above the lower part has the stop for a side edge of the document to be punched.
Im folgenden wird die Erfindung anhand eines in der Zeichnung in schematischer Weise dargestellten Ausfüh- rungsbeispiels näher erläutert.

Der in der Zeichnung dargestellte Mehrfachlocher be¬ steht im wesentlichen aus einem auf einer Unterlage aufstellbaren Unterteil 10, einem an Seitenwangen 12 des Unterteils 10 um eine horizontale Achse 14 schwenk¬ bar gelagerten, einen Handgriff 16 aufweisenden Druck¬ hebel 18, mehreren in einstellbaren Abständen vonein¬ ander am Unterteil 10 angeordneten Locheinheiten 20, einem in einer langgestreckten randoffenen Aussparung 22 des Unterteils 10 um seine Längsachse drehbar ange¬ ordneten Skalenträger 24 und einer in einer seitlich offenen Aussparung 26 des Unterteils 10 längsverschieb¬ bar angeordneten, einen Seitenanschlag 28 für das Schriftgut aufweisenden Anschlagschiene 30.The multiple hole punch shown in the drawing essentially consists of a lower part 10 which can be set up on a base, a pressure lever 18 which is pivotably mounted on side walls 12 of the lower part 10 about a horizontal axis 14 and has a handle 16, several at adjustable intervals from one another on the lower part 10, there are perforated units 20, a scale support 24 arranged in an elongated open-edge recess 22 of the lower part 10 about its longitudinal axis and one in a side open recess 26 of the lower part 10 arranged longitudinally displaceably, stop rail 30 having a side stop 28 for the writing material.
Die Locheinheiten 20 sind mit einer Vierkantöffnung 32 auf eine Vierkantstaπge 34 aus glasfaserverstärktem Kunststoff aufschiebbar und mittels je einer Stell¬ schraube 36 an beliebigen Positionen längs der Vier¬ kantstaπge 34 festklemmbar. Die Vierkantstange 34 bil¬ det mit den auf diese Weise aufgeklemmten Locheiπheiten 20 eine Baueinheit, die in ihrer Gesamtheit in das Lo¬ cherunterteil einsetzbar und aus diesem herausnehmbar ist. Zu diesem Zweck ist am Locheruπterteil außermittig ein Klemmhalter 38 aπgefor t, der eine nach oben offe¬ ne, durchgehende Öffnung 40 zur Aufnahme der Vierkant¬ staπge 34 sowie eine in die Öffnung 40 eingreifende, gegen die Vierkaπtstange anziehbare Stellschraube 42 aufweist.The perforated units 20 can be pushed onto a square rod 34 made of glass fiber reinforced plastic with a square opening 32 and can be clamped at any position along the square rod 34 by means of a set screw 36. The square rod 34, with the perforated units 20 clamped in this way, forms a structural unit which, in its entirety, can be inserted into and removed from the lower part of the hole. For this purpose, a clamp holder 38 is eccentrically arranged on the hole bottom part, which has an upwardly open, through opening 40 for receiving the square rods 34 and an adjusting screw 42 which engages in the opening 40 and can be tightened against the square rod.
Die einzelnen Locheinheiten 20 weisen in ihrem unteren Bereich einen Einschubschlitz 44 für das zu lochende Schriftgut, eine Lochmatrize 46 sowie einen unter der Einwirkung einer als Schraubendruckfeder 48 ausgebilde¬ ten Rückholfeder mit einem Sprengring 50 gegen einen oberen Endaπschlag 52 gehaltenen, mit seinem oberen En¬ de 54 über die Locheinheit 20 überstehenden Lochstempel 56 auf. Die Lochstempel 56 können durch Niederdrücken des Druckhebels 18 mit Hilfe des an ihm angeordneten Druckstegs 66 zum Zwecke eines Lochvorgangs durch den Einschubschlitz 44 und die Lochmatrize 46 entgegen der Kraft der Rückholfeder 48 nach unten verschoben werden.The individual perforation units 20 have in their lower area an insertion slot 44 for the documents to be perforated, a perforation die 46 and a return spring with a snap ring 50 held against an upper end stop 52 by the action of a return spring designed as a helical compression spring 48, with its upper end de 54 on the punch unit 20 protruding punch 56. The hole punches 56 can be pressed against the surface by pressing down the pressure lever 18 with the aid of the pressure bar 66 arranged on it for the purpose of a hole process through the insertion slot 44 and the hole die 46 Force of the return spring 48 to be moved down.
Im Bereich des Klemmhalters 38 ist am Unterteil 10 außerdem eine Halterung 58 angeformt, die eine vertikal ausgerichtete Führung für einen unter der Einwirkung einer Stützfeder 60 gegen den Drucksteg 66 des Druckhe¬ bels 18 anliegenden Stößel 62 aufweist. Der federunter¬ stützte Stößel 62 sorgt dafür, daß der Druckhebel 18 in seiner oberen Endstellung von den rückwärtigen Enden 54 der gegen ihren Endanschlag 52 gehaltenen Lochstempel 56 unter Bildung eines freien Zwischenraums 64 zwischen den Lochstempelenden 54 und dem Drucksteg 66 abgehoben wird. Dadurch werden die Locheinheiten druckfrei ge¬ stellt und können innerhalb des Unterteils leicht in ihrem gegenseitigen Abstand verstellt werden. Weiter kann dadurch die aus Vierkantstange 34 und Locheinhei¬ ten 20 bestehende Baueinheit nach Lösen der Stell¬ schraube 42 mit einem Handgriff aus dem Unterteil ent¬ nommen bzw. in dieses eingesetzt werden.In the area of the clamp holder 38, a holder 58 is additionally formed on the lower part 10, which has a vertically oriented guide for a plunger 62 which bears against the pressure web 66 of the pressure lever 18 under the action of a support spring 60. The spring-supported plunger 62 ensures that the pressure lever 18 is lifted in its upper end position from the rear ends 54 of the punch 56 held against its end stop 52 to form a free space 64 between the punch ends 54 and the pressure web 66. As a result, the punching units are set free of pressure and can be easily adjusted in their mutual spacing within the lower part. Furthermore, the structural unit consisting of square rod 34 and perforated units 20 can be removed with a handle from the lower part or inserted into it after loosening the set screw 42.
Wie insbesondere aus Fig. 3 zu ersehen ist, weist der Skalenträger 24 die Gestalt eines Rundstabes auf, an dessen Enden achszentral überstehende Lagerzapfen 68,70 angeformt sind. Der Rundstab mit den angeformten Lager¬ zapfen 68,70 wird zweckmäßig aus Kunststoff im Spritz¬ gußverfahren in Form von zwei längsgeteilten Stabhälf¬ ten 25 hergestellt (Fig. 4) , die unter Ergänzung zum Vollstab miteinander verrastet und/oder verklebt wer¬ den. Vor der Montage des Skalenträgers 24 wird auf den längeren Lagerzapfen 70 eine als Kunststoffspritzteil ausgebildete Lagerhülse 72 aufgeschoben und stirnseitig mit einem Drehknopf 74, der am Lagerzapfen drehfest be¬ festigt, vorzugsweise angeklebt wird, gegen ein Heraus¬ fallen gesichert. Der auf diese Weise vormontierte Ska¬ lenträger 24 wird sodann in die randoffene Aussparung 22 des Unterteils 10 eingeführt und mit seinem Lager¬ zapfen 68 in eine Lagerbohrung 76 eingesteckt. Weiter wird die Lagerhülse 72 mit ihrer Rastzunge 78 in einer nicht dargestellten Rastaussparung des Unterteils 10 drehfest eingerastet. An der Lagerhülse 72 ist außerdem eine Federzunge 80 aπgefor t, an deren freiem Ende ein radial nach innen weisender, in Rastausnehmungen 82 des Skalenträgers 24 einrastbarer Rastnocken 84 angeordnet ist. Damit kann der Skalenträger 24 in verschiedenen vorgegebenen Drehstellungen, in denen bestimmte Skalen 24* nach oben weisen, am Unterteil 10 arretiert werden.As can be seen in particular from FIG. 3, the scale carrier 24 has the shape of a round rod, on the ends of which axially projecting bearing journals 68, 70 are formed. The round rod with the integrally formed bearing journals 68, 70 is expediently made of plastic by injection molding in the form of two longitudinally divided rod halves 25 (FIG. 4), which are locked together and / or glued together to complement the solid rod. Before assembly of the scale carrier 24, a plastic injection-molded part is placed on the longer journal 70 trained bearing sleeve 72 pushed on and secured at the end with a knob 74, which is attached to the bearing journal in a rotationally fixed manner, preferably glued, to prevent it from falling out. The scale carrier 24 preassembled in this way is then inserted into the open-ended recess 22 of the lower part 10 and inserted with its bearing pin 68 into a bearing bore 76. Furthermore, the bearing sleeve 72 is locked with its locking tongue 78 in a locking recess, not shown, of the lower part 10 in a rotationally fixed manner. On the bearing sleeve 72 there is also a spring tongue 80 aπgefor t, at the free end of which is arranged a radially inwardly facing latching cam 84 which can be latched into latching recesses 82 of the scale carrier 24. The scale carrier 24 can thus be locked on the lower part 10 in various predetermined rotational positions, in which certain scales 24 * point upwards.
Zusammenfassend ist folgendes festzustellen: Die Erfin¬ dung bezieht sich auf einen Locher mit einem Locherun¬ terteil 10, mindestens zwei in ihrem gegenseitigen Ab¬ stand verstellbar angeordneten Locheinheiten 20 und ei¬ nem am Unterteil 10 schwenkbar gelagerten oder ver¬ schiebbar geführten Druckhebel 18 zum Verschieben der in den Locheiπheiten 20 angeordneten Lochstempel 56. Um mit einfachen und unverlierbaren Mitteln eine Vielzahl in der Praxis gebräuchliche Lochabstände einstellen zu können, befindet sich im Unterteil 10 eine sich über die Einschubl nge des Lochers erstreckende, nach oben raπdoffeπe langgestreckte Aussparung 22, in der ein sich um seine Längsachse drehbarer Skalenträger 24 an- geordnet ist, der mehrere in verschiedenen Drehlagen nach oben weisende, durch die Randöffnung sichtbare Skalen 24 trägt. Der Skalenträger 24 hat zweckmäßig die Gestalt eines Rundstabs, der in vorgegebenen Dreh¬ stellungen am Unterteil 10 einrastbar ist.
