Definitions
- the invention relates to a punch with adjustable Lochervzeugen according to the preamble of claim 1.
- the adjustability of punching tools of a punch is particularly required in so-called Mehrfachlochem designed for punching documents to be stored in folders or ring binders, in particular more than two Holes are to be introduced.
- the necessary perforations are to be made at different positions, including an adjustability is required accordingly.
- a conventional Mehrfachlocher is from the DE 41 36 721 A1 known.
- the punch described therein has a plurality of punching tools or punching units which can be fixed to a completely removable from the punch rail with fixing screws at different positions.
- the hole units there are pushed onto this rail individually from the side. It is not possible to remove a single punching tool without removing the entire rail from the device with all punching tools. Both the adjustment of the punching tools as well as the removal or addition of individual punching tools or punching units is therefore cumbersome.
- the invention is opposite to the generic DE 41 36 721 A1 the object of the invention to provide a punch with adjustable punching tools, which is more comfortable with respect to the adjustment of the punching tools. According to the invention this object is achieved by a punch with the features of claim 1.
- each punching tool has an adjustment key which acts on at least one spring and whose pressure releases its attachment to the receiving body of the punch, an adjustment is considerably simplified. It must not be performed as in conventional devices several movements such as the release of the pressure element and unscrewing screws, but a single movement over the pressing of the adjustment button is sufficient.
- the spring causes a sensible pressure to be required to release the fastener and the adjustment button then returns to its original position.
- the spring is biased and causes a clamping of the punching tool against the receiving body, so that the clamping effect is canceled by pressing the adjustment button.
- the adjustment button is released, the punching tool is then automatically fixed again in the selected position on the receiving body.
- a punch according to the invention is partially broken and shown with only one punching tool.
- the punch consists of a receiving body, which is formed by a base 1 and an actuating element 2 connected thereto.
- the actuator 2 has a molded handle 3, by the operation of the punching process can be performed.
- the hole punch shown is a so-called multiple hole punch, which has several, usually at least four, punching tools 4, of which only one is shown in the figures.
- punching the handle 3 of the actuating element 2 By punching the handle 3 of the actuating element 2, the punches 5 of the puncher tools 4 are moved so far down that they are at least partially immersed in the perforated die 6.
- the interspace 7 inserted paper In the interspace 7 inserted paper is characterized perforated.
- the process of punching is in the Fig. 3 (Home position) and 4 (depressed punch) shown.
- the punching tools 4 each have a foot part 8, with which they are guided in a receiving rail 9 of the base 1 slidably to change their position within the punch and to be able to adapt to different desired hole patterns.
- Fig. 2 The individual parts of a punching tool are in Fig. 2 shown in an exploded view.
- Fig. 3 shows the punch and the punch tool 4 in an initial position in which the punch tool 4 is fixed to the base 1, but just no punching operation is performed.
- the punch 5 of the punching tool 4 is located below a pressure axis 11 of the actuating element 2, but is not depressed by this in the position shown.
- the actuator 2 was actuated by pressing down the handle 3, whereby its pressure axis 11 has been moved down and thus the punch 5 has depressed so far that it is immersed in the die 6.
- a hole punch 5 surrounding hole pin spring 12 had to be depressed against its spring force.
- the Fig. 5 to 8 show how the punch tool 4 can be moved or adjusted.
- the punch tool 4 is fixed in the illustrated embodiment in a double manner to the receiving body of the punch.
- the hole pin spring 12 tensions the punch 5 against the pressure axis 11 of the Actuator 2.
- the punch tool 4 is already fixed to the receiving body of the punch.
- a clamping spring 13 a movably mounted pressure element 14 against the back of the receiving rail 9.
- On the other side of the clamping spring 13 is a rigid abutment 15, which is part of the punching tool 4.
- the foot part 8 of the punching tool 4 is clamped immovably in the receiving rail 9 of the receiving body.
- the adjustment button 16 is part of a pivotally mounted on a frame 17 of the punching tool 4 Verstellhebels 18.
- the adjusting lever 18 acts on a support forming a disc 19 and arranged underneath a locking washer 21 directly to the Lochtingfeder 12, so that these pressure on the adjustment button 16 is compressed against its biasing force.
- Fig. 5 shows a position in which the adjustment button 16 has already been pressed down slightly and thus the Lochchanfeder 12 is slightly compressed. In the illustration in Fig. 6 This movement was already continued, whereby the punch 5 is already shifted slightly downwards and thus no longer clamped against the pressure axis 11.
- the adjustment button 16 If the adjustment button 16 is pressed even further into the in Fig. 7 shown position, the adjusting lever 18 acts on a relief lever 22 and thus via the pressure element 14 on the clamping spring 13, which is thereby compressed.
- the relief lever 22 and the pressure element 14 are preferably integrally formed as shown. The clamping action between the pressure element 14 and the receiving rail 9 is thus canceled, and the punch tool 4 can be moved either in the receiving rail 9 to another position or as in Fig. 8 shown completely removed from the hole punch.
- the punch according to the invention provides a double attachment of the punching tool 4 on the receiving body of the punch on the through the pin spring 12 upwardly biased punch 5 on the one hand and the means of the clamping spring 13 against the base 1 depressed pressing member 14 on the other.
- the adjustment button 16 acts both on the Lochchanfeder 12 and on the clamping spring 13, on the latter indirectly via the relief lever 22.
- This compound is particularly clever realized by the fact that the relief lever 22 is guided in a guide 23, preferably by a groove is formed in the lateral cheeks of the adjusting lever 18.
- This guide 23 is designed so that during a first movement path of the adjusting lever 18, no movement of the relief lever 22 occurs and the release lever is pivoted only at a further depression of the adjustment button 16 so that the pressure element 14 detaches from the base 1.
- the operation and adjustment of the puncher tools 4 is particularly comfortable designed by the punch tool 4 has a counter-holder member 24 for stabilization upon actuation of the adjustment button 16.
- Counter support element 24 and adjustment button 16 are preferably arranged opposite one another and together form a pliers handle. The operation can be conveniently done by the thumb on the adjustment button 16, while the index or middle finger rests under the anvil member 24.
- the punching tool can also be held by means of the adjustment button 16 and the counter-holding element 24.
- the counter-holder element 24 can be formed by a rearward extension of the frame 17 of the punching tool 4. Preferred is as shown Also, the abutment 15 is formed directly as part of the anvil member 24.
- the punch according to the invention provides a particularly strong and secure support of the punching tools 4, which are still quickly and easily displaced or replaceable.
- the fact that the foot part 8 of the punching tool 4 is adapted in its fit to the receiving rail 9, but this is not overlapped on top, after pressing the adjustment button 16 is a simple removal of individual punching tools 4 from the punch possible without a complete disassembly of a support rod to make in conventional holes.
- the arrangement of the adjusting lever 18 and the loosening lever 22 loosely guided therein ensures that only the springs 12, 13 are under tension in the permanent positions in both the built-in and uninstalled state while the remaining components of the punching tool 4 are free of forces. So these parts can be made of plastic, without fear of creep or fatigue fractures.

Abstract
Description
Die Erfindung betrifft einen Locher mit verstellbaren Lochervverkzeugen nach dem Oberbegriff des Anspruchs 1. Die Verstellbarkeit von Locherwerkzeugen eines Lochers wird insbesondere bei sogenannten Mehrfachlochem gefordert, die zum Lochen von Dokumenten ausgelegt sind, die in Ordnern oder Ringbüchern abgelegt werden sollen, wenn insbesondere mehr als zwei Löcher eingebracht werden sollen. Bei verschiedenen Ordner- oder Ringbuchsystemen sind die notwendigen Lochungen an unterschiedlichen Positionen vorzunehmen, wozu dementsprechend eine Verstellbarkeit erforderlich ist.The invention relates to a punch with adjustable Lochervzeugen according to the preamble of

Der Erfindung liegt gegenüber der gattungsbildenden
Dadurch, daß jedes Locherwerkzeug eine Verstelltaste aufweist, die auf wenigstens eine Feder einwirkt und durch deren Drücken seine Festlegung am Aufnahmekörper des Lochers gelöst wird, ist eine Verstellung erheblich vereinfacht. Es müssen nicht wie bei herkömmlichen Geräten mehrere Bewegungsabläufe wie das Lösen des Druckorgans und das Losschrauben von Befestigungsschrauben durchgeführt werden, sondern ein einziger Bewegungsablauf über das Drücken der Verstelltaste ist ausreichend. Die Feder bewirkt, daß ein spürbarer Druck erforderlich ist, um die Befestigung zu lösen, und daß die Verstelltaste anschließend in ihre Ursprungsposition zurückkehrt. Bevorzugt ist die Feder vorgespannt und bewirkt eine Klemmung des Locherwerkzeugs gegen den Aufnahmekörper, so daß durch Druck auf Verstelltaste die Klemmwirkung aufgehoben wird. Bei Entlastung der Verstelltaste wird dann das Locherwerkzeug automatisch wieder in der gewählten Position am Aufnahmekörper fixiert.Due to the fact that each punching tool has an adjustment key which acts on at least one spring and whose pressure releases its attachment to the receiving body of the punch, an adjustment is considerably simplified. It must not be performed as in conventional devices several movements such as the release of the pressure element and unscrewing screws, but a single movement over the pressing of the adjustment button is sufficient. The spring causes a sensible pressure to be required to release the fastener and the adjustment button then returns to its original position. Preferably, the spring is biased and causes a clamping of the punching tool against the receiving body, so that the clamping effect is canceled by pressing the adjustment button. When the adjustment button is released, the punching tool is then automatically fixed again in the selected position on the receiving body.

In
Bei dem dargestellten Locher handelt es sich um einen sogenannten Mehrfachlocher, der mehrere, in der Regel mindestens vier, Locherwerkzeuge 4 aufweist, von denen in den Figuren jeweils nur eines dargestellt ist. Die Locherwerkzeuge 4 besitzen jeweils einen Lochstempel 5 und eine Lochmatrize 6. Durch Herunterdrücken des Griffs 3 des Betätigungselements 2 werden die Lochstempel 5 der Locherwerkzeuge 4 so weit nach unten verschoben, daß sie zumindest teilweise in die Lochmatrize 6 eintauchen. In den Zwischenraum 7 eingeschobenes Papier wird dadurch gelocht. Der Vorgang des Lochens ist in den
Die Locherwerkzeuge 4 haben jeweils einen Fußteil 8, mit dem sie in einer Aufnahmeschiene 9 der Basis 1 verschieblich geführt sind, um ihre Position innerhalb des Lochers zu verändern und verschiedenen gewünschten Lochmustern anpassen zu können.The

Die
Zum Verschieben oder Herausnehmen des Locherwerkzeugs 4 weist dieses eine Verstelltaste 16 auf. Die Verstelltaste 16 ist Teil eines schwenkbar an einem Rahmen 17 des Locherwerkzeugs 4 gelagerten Verstellhebels 18. Der Verstellhebel 18 wirkt über eine ein Auflager bildende Scheibe 19 und eine darunter angeordnete Sicherungsscheibe 21 direkt auf die Lochstiftfeder 12 ein, so daß diese bei Druck auf die Verstelltaste 16 entgegen ihrer Vorspannkraft komprimiert wird.
Wird die Verstelltaste 16 noch weiter heruntergedrückt, in die in
Der erfindungsgemäße Locher gewährt eine doppelte Befestigung des Locherwerkzeugs 4 am Aufnahmekörper des Lochers über den durch die Lochstiftfeder 12 nach oben vorgespannten Lochstempel 5 einerseits und das mittels der Klemmfeder 13 gegen die Basis 1 gedrückte Andrückelement 14 andererseits. Die Verstelltaste 16 wirkt dabei sowohl auf die Lochstiftfeder 12 als auch auf die Klemmfeder 13 ein, auf letztere mittelbar über den Entlastungshebel 22. Diese Verbindung ist besonders geschickt dadurch verwirklicht, daß der Entlastungshebel 22 in eine Führung 23 geführt ist, die bevorzugt durch eine Nut in den seitlichen Wangen des Verstellhebels 18 gebildet wird. Diese Führung 23 ist so ausgestaltet, daß während eines ersten Bewegungswegs des Verstellhebels 18 keine Bewegung des Entlastungshebels 22 eintritt und der Entlastungshebel erst bei einem weiteren Herunterdrücken der Verstelltaste 16 derart verschwenkt wird, daß sich das Andruckelement 14 von der Basis 1 löst.The punch according to the invention provides a double attachment of the
Bei der dargestellten Ausführungsform ist die Bedienung und Verstellung der Locherwerkzeuge 4 besonders komfortabel gestaltet, indem das Locherwerkzeug 4 ein Gegenhalterelement 24 zur Stabilisierung bei Betätigung der Verstelltaste 16 aufweist. Gegenhalterelement 24 und Verstelltaste 16 sind bevorzugt gegenüberliegend angeordnet und bilden gemeinsam einen Zangengriff aus. Die Betätigung kann bequem durch den Daumen auf der Verstelltaste 16 erfolgen, während der Zeige- oder Mittelfinger unter dem Gegenhalterelement 24 ruht. Bei einem Herausnehmen des Locherwerkzeugs 4 aus dem Locher kann das Locherwerkzeug so auch mittels der Verstelltaste 16 und dem Gegenhalterelement 24 gehalten werden. Auf einfache Weise kann das Gegenhalterelement 24 durch eine rückwärtige Verlängerung des Rahmens 17 des Locherwerkzeugs 4 gebildet werden. Bevorzugt wird wie dargestellt auch das Widerlager 15 direkt als Teil des Gegenhalterelements 24 ausgebildet.In the illustrated embodiment, the operation and adjustment of the
Der erfindungsgemäße Locher bietet eine besonders feste und sichere Halterung der Locherwerkzeuge 4, die dennoch schnell und komfortabel verschiebbar oder auswechselbar sind. Dadurch daß der Fußteil 8 des Locherwerkzeugs 4 in seiner Paßform an die Aufnahmeschiene 9 angepaßt ist, von dieser jedoch nicht obenseitig übergriffen wird, ist nach Betätigung der Verstelltaste 16 ein einfaches Entfernen auch einzelner Locherwerkzeuge 4 aus dem Locher möglich, ohne eine Komplettdemontage einer Halterungsstange wie bei herkömmlichen Lochern vornehmen zu müssen. Die Ausgestaltung mit Verstelltaste 16, insbesondere wenn noch ein Gegenhalterelement 24 vorgesehen ist, machen den Locher und die Verstellung der Locherwerkzeuge 4 selbsterklärend, so daß im Normalfall keine Anleitung herangezogen werden muß. Werden einzelne Locherwerkzeuge 4 nicht benötigt und aus dem Locher entfernt, so sorgt die Anordnung von Verstellhebel 18 und den darin lose geführten Entlastungshebel 22 dafür, daß in den Dauerpositionen sowohl in eingebautem als auch in nicht eingebautem Zustand lediglich die Federn 12,13 unter Spannung stehen, während die übrigen Bauteile des Locherwerkzeugs 4 kräftefrei sind. So können diese Teile aus Kunststoff gefertigt werden, ohne Kriechverformungen oder Ermüdungsbrüche befürchten zu müssen.The punch according to the invention provides a particularly strong and secure support of the
