Abstract

1. Letter punch including two components (1, 2) hingedly connected in the area of their longitudinal edges for the purpose of simultaneous punching of letters in two locations by way of two circular cylindrical cutters (12, 22) and co-acting templates (11, 21) whereby the two punch components (1, 2) are of identical shape, and each component comprises both a cut-out serving as template (11 or 21 respectively) and a circular cylindrical cutter (12 or 22 respectively) co-acting with the template (21 or 11 respectively) of the other component, characterised in that each punch component (1, 2) comprises two mounting flanges (13, 14; 23, 24) of which one has a mounting pin, and the other has a mounting eye to accommodate the mounting pin of the other punch component ; that each punch component (1, 2) is formed in one piece ; that a means for fixing the position (8, 19; 28, 29) relative to each other is formed onto the punch components (1, 2).

Description

Die Erfindung betrifft einen Brieflocher der im Oberbegriff des Anspruchs 1 angegeben Gattung.The invention relates to a letter punch in the preamble of claim 1 specified genus.

Brieflocher dieser Art, wie sie z. B. aus der DE-AS 26 46 778 bekannt sind, bestehen üblicherweise aus mehreren unter­ schiedlich geformten Teilen, für deren jedes ein Prägewerk­ zeug benötigt wird, und deren Zusammenbau meist nur unter Verwendung entsprechender Vorrichtungen möglich und daher aufwendig und zeitraubend ist.Punchers of this type, such as B. from DE-AS 26 46 778 are known, usually consist of several under differently shaped parts, each of which has an embossing unit Stuff is needed, and their assembly usually only under Use of appropriate devices possible and therefore is complex and time consuming.

Der Erfindung liegt die Aufgabe zugrunde, einen Brieflo­ cher der vorgenannten Art, insbesondere einen Brieflocher kleiner Abmessungen so auszubilden, daß die beiden den Brieflocher bildenden Teile mit nur einem Werkzeug her­ gestellt werden können und der Zusammenbau des Brieflo­ chers ohne zusätzliche Teile lediglich durch Verstemmen je eines Lagerteils erfolgen kann.The invention has for its object a brief cher of the aforementioned type, in particular a letter punch small dimensions so that the two the Parts forming letter punch with just one tool can be put and the assembly of the Brieflo chers without additional parts only by caulking one bearing part can be made.

Diese Aufgabe wird bei einem gattungsgemäßen Brieflocher dadurch gelöst, daß der Brieflocher die im Kennzeichen des Anspruchs 1 angegebenen Merkmale aufweist. Vorteilhafte Ausgestaltungen dieses Brieflochers ergeben sich aus den Unteransprüchen.This task is done with a generic letter punch solved in that the letter punch the in the license plate of claim 1 features specified. Beneficial Refinements of this letter punch result from the Subclaims.

In der Zeichnung ist ein Ausführungsbeispiel des erfin­ dungsgemäßen Brieflochers in schematischer Weise darge­ stellt. Es zeigt In the drawing, an embodiment of the inventions Brieflochers according to the invention in a schematic manner Darge poses. It shows  

Fig. 1 die beiden Teile des Brieflochers vor ihrem Zusam­ menbau in Draufsicht, Fig. 1, the two parts of the letter punch before its menbau together in plan view,

Fig. 2 eine schaubildliche Darstellung des zusammenge­ bauten Brieflochers. Fig. 2 is a diagrammatic representation of the assembled hole punch.

Der Brieflocher besteht aus den beiden Teilen 1 und 2, die ein zweimalig Z-förmig abgebogenes Profil aufweisen, so daß die beiden Randstreifen 15 und 16 bzw. 25 und 26 in einer Ebene liegen und der Mittelteil 17 bzw. 27 in einer dazu parallelen Ebene liegt. Jedes dieser beiden Mittelteile 17 bzw. 27 weist eine als Matrize dienende Aussparung 11 bzw. 21 sowie eine im Ziehverfahren herge­ stellte kreisförmige Schneide 12 bzw. 22 auf. An den Enden der beiden Randstreifen 16 bzw. 26 sind Lagerlappen 13, 14 bzw. 23, 24 senkrecht abgebogen, von denen die einen, 13 bzw. 23 einen hülsenförmig ausgebildeten Lagerzapfen und die anderen, 14 bzw. 24 ein Lagerauge aufweisen. Die Vor­ derkanten dieser Lagerlappen 13, 14, 23, 24 bilden einen An­ schlag für das zu lochende Schriftgut; die Lagerachse er­ streckt sich in der Ebene der Mittelteile 17 bzw. 27. Beim Zusammenbau brauchen die beiden Teile 1, 2 nur ineinander­ gesteckt und die die Lagerzapfen bildenden Hülsen ver­ stemmt zu werden. Zur Fixierung der gegenseitigen Lage der beiden Teile 1, 2, insbesondere auch bei dem Zusammen­ bau, sind an den die Lagerlappen 13, 14, 23, 24 aufweisenden Randstreifen 16 und 26 im zusammengebauten Zustand ineinan­ dergreifende Zungen 18, 19 bzw. 28, 29 abgebogen.The letter punch consists of the two parts 1 and 2 , which have a twice Z-shaped profile, so that the two edge strips 15 and 16 or 25 and 26 lie in one plane and the middle part 17 and 27 in a plane parallel to it lies. Each of these two central parts 17 and 27 has a recess 11 and 21 serving as a die and a circular cutting edge 12 and 22, respectively, which is produced using the drawing method. At the ends of the two edge strips 16 and 26 , bearing tabs 13, 14 and 23, 24 are bent vertically, of which one, 13 and 23 have a sleeve-shaped bearing pin and the other, 14 and 24 have a bearing eye. In front of the edges of this bearing flap 13, 14, 23, 24 form an impact on the documents to be punched; the bearing axis he stretches in the plane of the middle parts 17 and 27 . When assembling the two parts 1, 2 only need to be inserted into each other and the sleeves forming the journals to be stemmed ver. To fix the mutual position of the two parts 1, 2 , in particular also when assembling, are on the bearing tabs 13, 14, 23, 24 having edge strips 16 and 26 in the assembled state interlocking tongues 18, 19 and 28, 29th turned.
