Definitions

  • the present invention relates to a paper punch.
  • Paper punches with which parts of the file are punched for filing are known in a wide variety of designs. Thus, small punches are described in pocket size (DE-OS 28 41 441; DE-OS 22 10 794; DE-GM 73 07 954), which have only one punch and a punch hole with which the paper to be punched is punched in the folded state , resulting in two holes. In these holes, there is a problem that the punch is canted in the punch hole because it moves in a circular path in the punching operation.
  • DE 32 30 312 A1 discloses a punch for paper and cardboard products, in which the punch runs in a guide and is pressed by means of a pressure plate designed as a shell on the paper to be punched.
  • the upper part is pivotally connected to the lower part. Due to the leadership of the punch whose tilting is avoided during the punching process.
  • Object of the present invention is to provide a punch that allows both in the design as a small pocket punch with only a punch and in the usual office punch design exact guidance of the punch to the punch hole in the simplest way and without expensive construction.
  • the invention can also be used for punches with more than two punches, such as those used for punches of so-called ring binder inserts that cause more than two perforations, for example, three or four.
  • the outer edge of the hollow section will be deformed elastically, for example if the longer edges of the rectangular profile are bent Rectangular profile moves parallel to the second shorter edge of the rectangular profile, so that there is no tilting of the arranged in the region of the outer edge punch. It is not necessary that the entire leg is designed as a hollow profile. It is sufficient if a longer section is designed accordingly.
  • both legs are formed as hollow profiles.
  • the invention makes it possible to provide punches which consist only of two elastic, interconnected legs, on which one or more punches and the corresponding punched holes are arranged. A lever or spring mechanism is no longer required.
  • the punch of Figures la to lc includes a punch 14 of a sharpened at the edges round pin, which is in a shorter boundary wall 24 of a hollow profile 20, which forms a first leg 10 of the punch is arranged.
  • the first leg 10 is connected by a connecting part 26, for example in the form of a pin, with a second leg 12, which is also formed from a hollow profile 20.
  • Both hollow profiles 20 are made of a resilient plastic, which in the direction in which both legs can be moved toward each other due to their elasticity, which is referred to as punching direction S.
  • punching direction S By compressing the legs 10,12 in the punching direction S of the punch 14 is guided into the punch hole 16, whereby the punching operation is effected.
  • Figure la shows the punch in the initial state, Figure 1b in the compressed state in which the punching process is completed.
  • Figure 2a and 2b shows another embodiment as an office punch, with which in a conventional manner two punched openings can be produced in a sheet. This embodiment is obtained by doubling the functional elements of the embodiment of FIGS. 1a-c.
  • the reference numerals correspond to each other in the illustration.

Claims (4)

  1. Perforatrice pour papier et autres feuilles fines de nature similaire, avec au moins un cylindre perforateur (14) placé sur un bras mobile et élastique (10), qui conjugue son action dans le sens de perforation à celle d'au moins un trou de perforation situé sur un second bras (12) auquel le premier bras (10) est relié de manière mobile et élastique,
    caractérisée en ce qu'au moins l'un des bras (10, 12) est réalisé comme profil creux élastique de forme rectangulaire dans la coupe du plan du sens d'estampage (S), au moins les longues parois de délimitation (22) étant constituées d'un matériau élastique, et
    que (lors de son utilisation), en raison de la section rectangulaire des bras élastiques (10, 12), les longues parois de délimitation (22) se déforment parallèlement l'une à l'autre, ce qui conduit à ce que la paroi de délimitation courte (34) sur laquelle se trouve le bloc perforateur, est parallèle à la paroi de délimitation courte située sur le côté opposé (24).
  2. Perforatrice selon la revendication 1, caractérisée en ce qu'elle est munie d'un seul cylindre perforateur (14) et d'un seul trou de perforation (16) comme perforatrice de petite taille ou de poche.
  3. Perforatrice selon la revendication 1, caractérisée en ce qu'elle est munie de deux cylindres perforateurs (14) et de deux trous de perforation (16) comme perforatrice de bureau.
  4. Perforatrice selon la revendication 1, caractérisée en ce que les deux bras (10, 12) sont réalisés comme profiles creux élastiques.
