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 angegebenen Gattung.The invention relates to a letter punch of the type specified in the preamble of claim 1.

Brieflocher dieser Art, wie sie z.B. aus der DE-AS 26 46 778 bekannt sind, bestehen üblicherweise aus mehreren unter­schiedlich geformten Teilen, für deren jedes ein Prägewerk­zeug benötigt wird, und deren Zusammenbau meist nur unter Verwendung entsprechender Vorrichtungen möglich und daher aufwendig und zeitraubend ist.Letter puncher of this type, e.g. are known from DE-AS 26 46 778, usually consist of several differently shaped parts, each of which requires an embossing tool, and their assembly is usually only possible using appropriate devices and is therefore complex and time-consuming.

Der Erfindung liegt die Aufgabe zugrunde, einen Brieflo­cher der vorgenannten Art, insbesondere einen Brieflocher kleiner Abmessungen so auszubilden, daß die beiden den Brieflocher bildenden Teile mit nur einem Werkzeug her­gestellt werden können und der Zusammenbau des Brieflo­chers ohne zusätzliche Teile lediglich durch Verstemmen je eines Lagerteils erfolgen kann.The invention has for its object to provide a punch hole punch of the aforementioned type, in particular a punch hole punch of small dimensions so that the two parts forming the punch hole punch can be produced with only one tool and the assembly of the punch hole punch can be done without additional parts simply by caulking one bearing part each can.

Diese Aufgabe wird bei einem gattungsgemäßgen Brieflocher dadurch gelöst, daß dr Brieflocher die im Kennzeichen des Anspruchs 1 angegebenen Merkmale aufweist. Vorteilhafte Ausgestaltungen dieses Brieflochers ergeben sich aus den Unteransprüchen.This object is achieved in a generic letter punch that dr letter punch has the features specified in the characterizing part of claim 1. Advantageous refinements of this letter punch result from the subclaims.

In der Zeichnung ist ein Ausführungsbeispiel des erfin­dungsgemäßen Brieflochers in schematischer Weise darge­stellt. Es zeigen

  • Fig. 1 die beiden Teile des Brieflochers vor ihrem Zusam­menbau in Draufsicht,
  • Fig. 2 eine schaubildliche Darstellung des zusammenge­bauten Brieflochers.
In the drawing, an embodiment of the letter punch according to the invention is shown in a schematic manner. Show it
  • 1 is a plan view of the two parts of the letter punch before they are assembled,
  • Fig. 2 is a diagrammatic representation of the assembled punch 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 herge­stellte 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 Vor­derkanten dieser Lagerlappen 13,14,23,24, bilden einen An­schlag für das zu lochende Schriftgut; die Lagerachse er­streckt sich in der Ebene der Mittelteile 17 bzw. 27. Beim Zusammenbau brauchen die beiden Teile 1,2 nur ineinander­gesteckt und die die Lagerzapfen bildenden Hülsen ver­stemmt zu werden. Zur Fixierung der gegenseitigen Lage der beiden Teile 1,2, insbesondere auch bei dem Zusammen­bau, sind an den die Lagerlappen 13,14,23,24 aufweisenden Randstreifen 16 und 26 im zusammengebauten Zustand ineinan­dergreifende 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 middle parts 17 and 27 has a recess 11 and 21 serving as a matrix and a circular cutting edge 12 and 22 produced by the drawing process. 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. The front edges of these bearing tabs 13, 14, 23, 24 form a stop for the documents to be punched; the bearing axis extends in the plane of the middle parts 17 and 27. When assembled, the two parts 1, 2 only need to be plugged into one another and the sleeves forming the bearing journals have to be caulked. To fix the mutual position of the two parts 1, 2, in particular also during assembly, tongues 18, 19 and 28, 29 which engage in one another in the assembled state are bent on the edge strips 16 and 26 which have the bearing tabs 13, 14, 23, 24.
