Abstract

1. A single-hole paper punch having a cutting die and a punch movable with respect thereto, wherein the cutting die (15) is formed in the base-plate (1) of a hold-down strip of a letter-file, and the punch is arranged on a rocker (2) mounted on the base-plate (1) of the hold-down strip.

Description

Die Erfindung betrifft einen Einfach-Brieflocher, der in Ermangelung eines üblichen Brieflochers, beispielsweise bei Besprechungen oder auf Reisen zum Lochen von Schriftgut dienen kann und den Vorteil sehr kleiner Abmessungen aufweist.The invention relates to a single letter punch, which, in the absence of a conventional letter punch, can be used for punching documents, for example at meetings or when traveling, and has the advantage of very small dimensions.

Da eine Veranlassung, Schriftgut zu lochen, nur dann besteht, wenn die Möglichkeit einer Ablage des Schriftgutes in einem Briefordner oder auch Schnellhefter gegeben ist, bietet sich die Niederhalteschiene eines Briefordners mit ihrer schwenkbar gelagerten Wippe zur Ausbildung eines Mehrzweckgeräts an vgl. DE-A-2 907 718. Eine Niederhalteschiene nach der Lehre der DE-A-2 319 904 eignet sich hierfür in besonderem Mass, weil die Wippe dieser Niederhalteschiene auch in gelöstem Zustand verhältnismässig flach auf der Grundplatte der Niederhalteschiene aufliegt und somit auch für sich allein in einem Schnellhefter, gegen dessen Rückenfalz anliegend, aufbewahrt werden kann, ohne dessen Vorderdeckel abzuspreizen. Eine Niederhalteschiene dieser Art eignet sich auch deshalb zur Ausbildung als Mehrzweckgerät, weil die Wippe in Längsrichtung der Grundplatte spielfrei gelagert ist.Since there is no reason to punch documents, only if the documents can be stored in a letter folder or also in a flat file, the hold-down rail of a letter folder with its swivel-mounted rocker is suitable for the formation of a multi-purpose device cf. DE-A-2 907 718. A hold-down rail according to the teaching of DE-A-2 319 904 is particularly suitable for this because the rocker of this hold-down rail lies relatively flat on the base plate of the hold-down rail even in the released state and thus also for itself alone in a flat file, against the back fold, can be stored without spreading the front cover. A hold-down rail of this type is also suitable for training as a multipurpose device because the rocker is mounted without play in the longitudinal direction of the base plate.

Die Doppelfunktion einer Niederhalteschiene wird gemäss der Erfindung dadurch erzielt, dass diese die Merkmale des Patentanspruches 1 aufweist. Bei einer solchen Ausbildung einer Niederhalteschiene wird der Abstand des an der Wippe angeformten Lochstempels von dem auf die Längsfederdrähte wirkenden Spreiznocken bzw. von den auf die Längsfederdrähte wirkenden Klemmzungen so bemessen, dass der Spreiznokken bzw. die Klemmzungen als Anschlag für das zu lochende Schriftgut dienen können und so eine vorbestimmte Randstreifenbreite gewährleistet ist.The double function of a hold-down rail is achieved according to the invention in that it has the features of claim 1. With such a design of a hold-down rail, the distance of the punch formed on the rocker from the expanding cams acting on the longitudinal spring wires or from the clamping tongues acting on the longitudinal spring wires is dimensioned such that the expanding cam or the clamping tongues can serve as a stop for the documents to be punched and thus a predetermined edge strip width is guaranteed.

Vorteilhafterweise weist die als Einfach-Brieflocher verwendbare Niederhalteschiene die Merkmale auf, die das Kennzeichen der Patentansprüche 3 und 4 bilden.The hold-down rail which can be used as a single letter punch advantageously has the features which form the characterizing part of patent claims 3 and 4.

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

  • Fig. 1 eine schaubildliche Darstellung der Niederhalteschiene in Explosionsdarstellung;
  • Fig. 2 einen senkrechten Längsschnitt durch die Niederhalteschiene mit abgehobener Wippe.
In the drawing, an embodiment of the subject of the invention is shown in a schematic manner. Show it
  • Figure 1 is a diagrammatic representation of the hold-down rail in an exploded view.
  • Fig. 2 shows a vertical longitudinal section through the hold-down rail with the rocker raised.

Die Grundplatte 1 der Niederhalteschiene weist zwei Durchbrüche 11 auf, durch die die Lagerzungen 21 der Wippe 2 hindurchgreifen. In ihrem mittleren Bereich weist die Grundplatte 1 zwei Aussparungen 12 auf, durch die die beiden, auf die Längsfederdrähte 3 einwirkenden Klemmzungen 22 hindurchgreifen. Angrenzend an die Durchbrüche 13 für die Aufreihstifte einer Aufreihvorrichtung sind Halterungen 14 für die Längsfederdrähte 3 vorgesehen. Der kreisrunde Durchbruch 15 der Grundplatte 1 bildet die Schnittmatrize, in die der an der Wippe 2 angeformte Lochstempel 23 eingreift. An der Wippe ist eine Kerbe 24 als Mittenanzeiger vorgesehen.The base plate 1 of the hold-down rail has two openings 11 through which the bearing tongues 21 of the rocker 2 extend. In its central region, the base plate 1 has two cutouts 12 through which the two clamping tongues 22 acting on the longitudinal spring wires 3 extend. Adjacent to the openings 13 for the aligning pins of a aligning device, holders 14 are provided for the longitudinal spring wires 3. The circular opening 15 of the base plate 1 forms the cutting die, into which the punch 23 formed on the rocker 2 engages. A notch 24 is provided on the rocker as a center indicator.

Claims (4)

1. A single-hole paper punch having a cutting die and a punch movable with respect thereto, wherein the cutting die (15) is formed in the base-plate (1) of a hold-down strip of a letter-file, and the punch is arranged on a rocker (2) mounted on the base-plate (1) of the hold-down strip.
2. A single-hole paper punch according to claim 1, wherein the width of the margin on the sheets of written material to be punched is determined by the gap between the punch (23) and separating or clamping cam means (22) arranged on the rocker (2) and acting on longitudinal spring wires (3).
3. A single-hole paper punch according to claims 1 or 2, wherein the punch (23) is constituted by a hollow cylindrical plug pressed out of the rocker (2).
4. A single-hole paper punch according to any one of claims 1 to 3, wherein longitudinal spring wires (3) are arranged below the base plate (1) of the hold-down strip.
