Description

Die Erfindung betrifft einen Lochapparat zum gleichzeitigen Stanzen von mindestens zwei Löchem in Papier, umfassend ein Gehäuse mit einer Standfläche, eine im Gehäuse schwenkbar gelagerte Wippe mit einer Tastfläche, mindestens zwei durch die Wippe betätigte Stanzbolzen mit je einer zugeordneten Büchse, sowie einen annähemd senkrecht zur Standfläche angeordneten Schlitz zum Einführen des Papiers.The invention relates to a punching device for simultaneously punching at least two holes in paper, comprising a housing with a base, a rocker pivotally mounted in the housing with a tactile surface, at least two punching bolts actuated by the rocker, each with an associated bushing, and an approximately perpendicular to the Stand slot arranged for insertion of the paper.

Es sind bereits Locher dieser Art bekannt (DE-C-722500, FR-A-1 431 020) bei denen das zu lochende Papier von oben in einen senkrecht zur Standfläche angeordneten Schlitz eingeführt wird. Da der geradlinig verlaufende Schlitz zum Lochen von Papier nur eine verhältnismäßig geringe Tiefe aufweist, neigt das in den Schlitz eingebrachte Papier zum Abkippen über die Kante des Schlitzes und muß deshalb von großen, schräg nach oben gerichteten Anlegeplatten in seiner Stellung gehalten werden.Punchers of this type are already known (DE-C-722500, FR-A-1 431 020) in which the paper to be punched is inserted from above into a slot arranged perpendicular to the base. Since the rectilinear slot for punching paper has only a relatively small depth, the paper introduced into the slot tends to tip over the edge of the slot and must therefore be held in position by large, obliquely upward-facing contact plates.

Aufgabe der Erfindung ist es, einen Lochapparat der eingangs angegebenen Art zu schaffen, bei dem das in den senkrechten Schlitz eingeführte Papier von selbst in senkrechter Lage stehen bleibt.The object of the invention is to provide a perforating apparatus of the type specified at the outset, in which the paper inserted into the vertical slot remains in a vertical position by itself.

Zur Lösung dieser Aufgabe wird vorgeschlagen, den Schlitz gekrümmt auszuführen. Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des Erfindungsgedankens ergeben sich aus den Unteransprüchen.To solve this problem, it is proposed to make the slot curved. Further advantageous refinements and developments of the inventive concept result from the subclaims.

Durch die gekrümmte Anordnung des Schlitzes wird ein Umkippen des eingeführten Papiers über die Kante des Schlitzes verhindert und dadurch die einhändige Bedienung des Apparats wesentlich erleichtert.The curved arrangement of the slot prevents the inserted paper from tipping over over the edge of the slot, thereby considerably simplifying the one-handed operation of the apparatus.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung erläutert. Darin zeigt :

  • Fig. 1 eine Frontansicht,
  • Fig. 2 eine Draufsicht,
  • Fig. 3 eine Seitenansicht,
  • Fig. 4 eine Draufsicht mit abgehobenem Oberteil,
  • Fig. 5 einen Schnitt längs der Linie V-V in Fig. 4,
  • Fig. 6 einen Schnitt längs der Linie VI-VI in Fig. 4,
  • Fig. 7 einen Schnitt längs der Linie VII-VII in Fig. 4, und
  • Fig. 8 einen Schnitt längs der Linie VIII-VIII in Fig. 4.
An exemplary embodiment of the invention is explained below with reference to the drawing. It shows:
  • 1 is a front view,
  • 2 is a plan view,
  • 3 is a side view,
  • 4 is a plan view with the upper part lifted off,
  • 5 shows a section along the line VV in FIG. 4,
  • 6 shows a section along the line VI-VI in FIG. 4,
  • Fig. 7 is a section along the line VII-VII in Fig. 4, and
  • 8 shows a section along the line VIII-VIII in FIG. 4.

Der dargestellte Lochapparat hat ein aus einem Oberteil 1 und einem Unterteil 2 bestehendes Gehäuse. Vier im Unterteil 2 in Rähmchen 26 eingesetzte Gummifüsse 6 mit adhäsiver Oberfläche bilden eine Standfläche 9 und verhindern ein Verrutschen auch auf glatter Unterlage. Ein Schlitz 11 mit einer Einführung 12 für das Papier ist im Oberteil 1 nach oben gerichtet, also senkrecht zur Standfläche 9 angeordnet und somit gut sichtbar. Beim Stanzen mehrerer Blätter gleichzeitig müssen diese nicht erst gebündelt werden ; dies geschieht von selbst bei senkrechter Zuführung durch die Schwerkraft des Papiers am Schlitzboden 13. Der Schlitz 11 ist gekrümmt. Dies hat den Vorteil, dass das eingeführte Papierblatt nicht vor und rückwärts umkippt. Dadurch wird die einhändige Bedienung des Apparates wesentlich erleichtert. Eine Papierandrückfeder 24 verhindert das Abkippen des Blattes, wenn mehr als dis Hälfte seiner Länge seitlich aus dem Schlitz 12 herausragt. Die kalottenförmige Gestalt der Andrückfederfläche 25 erleichtert die Papiereinführung.The perforated apparatus shown has a housing consisting of an upper part 1 and a lower part 2. Four rubber feet 6 with an adhesive surface inserted in the frame 2 in frames 26 form a base 9 and prevent them from slipping even on a smooth surface. A slot 11 with an insertion 12 for the paper is directed upwards in the upper part 1, that is to say it is arranged perpendicular to the base 9 and is thus clearly visible. When punching several sheets at the same time, they do not have to be bundled first; this happens automatically with vertical feeding due to the gravity of the paper on the slot bottom 13. The slot 11 is curved. This has the advantage that the inserted paper sheet does not tip over backwards and forwards. This makes it much easier to operate the device with one hand. A paper pressure spring 24 prevents the sheet from tipping over if more than half of its length protrudes laterally from the slot 12. The dome-shaped shape of the pressure spring surface 25 facilitates paper insertion.

In halbrunden, als Lager 22 ausgebildeten Ausnehmungen im Unterteil 2 ist ein zylindrischer Zapfen 35 einer als Winkelhebel 32 ausgebildeten Wippe 3 gelagert. Der Zapfen 35 ist durch eine mit dem Oberteil 1 einstückige Feder 16 in den Lagern 22 gehalten. Der eine Schenkel der Wippe 3 hat eine aus dem Oberteil 1 herausragende Tastfläche 31. Der andere Schenkel greift mit je einem Schlitz 36 in je eine Umfangsnut zweier metallener Stanzbolzen 7 ein, welche in je einer Lagerstelle 27 im Unterteil 2 verschiebbar gelagert sind. Beim Betätigen der Wippe 3 durch Druck auf die Tastfläche 31 gegen die Kraft zweier gegen Lageböcke 19 anliegender Blattfedem 33 werden die Stanzbolzen 7 axial durch den Schlitz 12 in gegenüberliegende metallene Büchsen 8 eingeschoben. Die Büchsen 8 sind in Ausnehmungen 28 im Unterteil 2 eingeschnappt und durch das Oberteil 1 gehalten. Die Bohrung der Büchsen 8 ist gegen einen Abfallkanal 15 hin erweitert, der im Oberteil 1 ausgebildet und durch einen verschiebbaren Deckel 5 verschlossen ist.A cylindrical pin 35 of a rocker 3 designed as an angle lever 32 is mounted in semicircular recesses in the lower part 2 designed as a bearing 22. The pin 35 is held in the bearings 22 by a spring 16 integral with the upper part 1. One leg of the rocker 3 has a tactile surface 31 protruding from the upper part 1. The other leg engages with a slot 36 in a circumferential groove of two metal punching bolts 7, which are each slidably mounted in a bearing 27 in the lower part 2. When the rocker 3 is actuated by pressing the touch surface 31 against the force of two leaf springs 33 bearing against bearing blocks 19, the punching bolts 7 are inserted axially through the slot 12 into opposing metal bushes 8. The sleeves 8 are snapped into recesses 28 in the lower part 2 and held by the upper part 1. The bore of the bushes 8 is expanded towards a waste channel 15, which is formed in the upper part 1 and is closed by a sliding cover 5.

Das Entleeren der Stanzabfälle kann ganz gezielt auch in kleine Behältnisse erfolgen, indem der seitlich angebrachte Deckel 5 nach oben verschoben wird, so dass der Abfallkanal 15 freigegeben ist Die Deckelführung 17 ist nach oben begrenzt, damit der Deckel 5 nicht verlorengehen kann.The punching waste can also be emptied into small containers in a very targeted manner, in that the laterally attached lid 5 is moved upward, so that the waste channel 15 is released. The lid guide 17 is limited at the top so that the lid 5 cannot be lost.

Die durch die Lager 22 und die Feder 16 gebildete Ueberlastsicherung verhindert eine mögliche Beschädigung des Apparates wie folgt : Ist die auf die Tastfläche 31 aufgebrachte Kraft grösser als die zulässige, springt die Wippe 3 mit ihrem Zapfen 35 aus den Lagern 22. Die Rückführung bei verklemmten Stanzbolzen 7 in die Normalstellung geschieht dadurch, dass ein zylindrischer Gegenstand, z. B. ein Bleistift, durch ein Loch 23 im Unterteil 2 geführt und durch Druck auf die Innenfläche 34 der Wippe 3 diese nach oben zurückgestellt wird.The overload protection formed by the bearings 22 and the spring 16 prevents possible damage to the apparatus as follows: If the force applied to the touch surface 31 is greater than the permissible, the rocker 3 jumps out of the bearings 22 with its pin 35 Punching pin 7 in the normal position happens in that a cylindrical object, for. B. a pencil, passed through a hole 23 in the lower part 2 and this is reset by pressing the inner surface 34 of the rocker 3 upwards.

Der Apparat hat vier verschiebbare Tasten 4 zum Einstellen der zu stanzenden Formatgrössen DIN A4, DIN A5 und DIN A6. Durch Verschieben der Taste 4 in Pfeilrichtung wird ein von oben gut sichtbarer Anschlag 41 für die Papierblätter in eine Aussparung 14 geschoben. Beim Format DIN A4 können bei betätigter äusserster Taste 43 zwei Löcher mittig gestanzt werden oder bei betätigter innerster Taste 42 vier Löcher, indem nach dem ersten Stanzvorgang das Blatt gewendet wird und die Wippe 3 erneut betätigt wird. Dis Anzahl Löcher ist durch verständliche Symbole 44 auf den einzelnen Schiebetasten 4 markiert. Dis Tasten 4 stellen sich beim Aendern der Formateinstellung automatisch zurück. Dies geschieht dadurch, dass beim Verschieben der einen Taste 4 in Schlitzrichtung über einen angeschrägten Nocken 45 unter der Taste 4 ein im Gehäuseunterteil angebrachter Bügel 21 mit entsprechenden Rasten 46 seitwärts bewegt wird. Durch diese Verschiebung wird der eingerastete Nocken 45 einer früher betätigten Taste freigegeben, welche, durch Federbeine 47 gespannt, in die Ausgangsstellung zurückspringt.The apparatus has four sliding buttons 4 for setting the format sizes to be punched, A4, A5 and A6. By moving the button 4 in the direction of the arrow, a stop 41 for the paper sheets, which is clearly visible from above, is pushed into a recess 14. In the A4 format, two holes can be punched in the middle when the outermost button 43 is pressed, or four holes when the innermost button 42 is pressed, by turning the page after the first punching process and the rocker 3 is operated again. The number of holes is marked by understandable symbols 44 on the individual sliding buttons 4. The 4 buttons are automatically reset when the format setting is changed. This is done in that when a button 4 is moved in the slot direction via a beveled cam 45 under button 4, a bracket 21 attached in the lower housing part with corresponding notches 46 is moved sideways. As a result of this displacement, the latched cam 45 of a previously actuated key is released, which, stretched by spring struts 47, springs back into the starting position.

Mit Ausnahme der Stanzbolzen 7 und der Büchsen 8 bestehen sämtliche Teile aus Kunststoff.With the exception of the punch bolts 7 and the bushes 8, all parts are made of plastic.

Der Zusammenbau des Apparates kann ohne spezielle Hilfswerkzeuge vorgenommen werden. Es wird dabei wie folgt vorgegangen: Vier selbstklebende Gummifüsse 6 werden in die Rähmchen 26 an der Unterseite des Unterteils 2 aufgebracht. Die Wippe 3 wird mit ihrem runden Zapfen 35 in die Lager 22 eingesetzt. Zwei Stanzbolzen 7 werden mit den Schlitzen 36 des Winkelhebels 32 in Eingriff gebracht und in ihre Lagerstellen 27 eingeschnappt. Die zwei Büchsen 8 werden ebenfalls in die Ausnehmungen 28 auf gleicher Achse wie die Stanzbolzen 7 eingeschnappt. Der einstückige Bauteil bestehend aus den Schiebetasten 4, den Federbeinen 47, den Nocken 45 und den Anschlägen 41 wird so in das Unterteil 2 eingesetzt, dass die vier verstellbaren Anschläge 41 in ihren paarweise angeordneten Führungsnuten 29 gelagert sind. Die Federbeine 47 liegen dabei an Rippen 30 an. Der Deckel 5 wird seitlich in die T-Nut des Gehäuseoberteils 1 eingeführt. Das Gehäuseoberteil 1 wird über Schnapparme 20, die im Unterteil 2 angeformt sind, unlösbar mit diesem verbunden.The apparatus can be assembled without special auxiliary tools. The procedure is as follows: Four self-adhesive rubber feet 6 are applied to the frame 26 on the underside of the lower part 2. The rocker 3 is inserted with its round pin 35 into the bearing 22. Two punch bolts 7 are brought into engagement with the slots 36 of the angle lever 32 and snapped into their bearing points 27. The two sleeves 8 are also snapped into the recesses 28 on the same axis as the punch bolts 7. The one-piece component consisting of the sliding buttons 4, the spring struts 47, the cams 45 and the stops 41 is inserted into the lower part 2 in such a way that the four adjustable stops 41 are mounted in their guide grooves 29 arranged in pairs. The struts 47 rest against ribs 30. The cover 5 is inserted laterally into the T-groove of the upper housing part 1. The upper housing part 1 is non-releasably connected to the latter by means of snap arms 20 which are molded onto the lower part 2.

Die beschriebene einfach und preisgünstig herstellbare Tastenanordnung ist auch in anderen Geräten als Lochern einsetzbar, z. B. für Wahlschalter in elektrischen Geräten. Dabei kann eine der Tasten ohne weiteres als reine Rückstelltaste ausgebildet werden, indem ihr Nocken 45 so lang ausgebildet wird, dass er an der zugehörigen Raste 46 nicht einrastet. Auch die beschriebene Ueberlastsicherung ist allgemein bei Schwenkhebeln anwendbar.The described simple and inexpensive to produce button arrangement can also be used in devices other than punches, for. B. for selector switches in electrical devices. In this case, one of the keys can easily be designed as a pure reset key, in that its cam 45 is formed so long that it does not snap into the associated catch 46. The overload protection described is also generally applicable to swivel levers.
