Definitions

  • the invention relates to a punch with a lower part that can be set up on a base, at least two perforated matrices, an insertion slot and one from an upper end position, counter to the force of a return spring through the insertion slot and the punching units which can be displaced through the punching die, and a pressure member for displacing the punching punch, which is pivotably mounted or displaceably guided on the lower part and acts against the rear end faces of the punching punch, preferably designed as a pressure lever.
  • the perforation units which are adjustable in their spacing from one another, it is possible to adapt the perforator to different perforation spacings in the documents to be perforated.
  • the punch units are lined up on a round rod which is mounted in bearing holes in the side walls of the punch lower part.
  • the assembly of the perforated units therefore takes place within the perforator with the round rod partially pulled out of its bearing, the spacing between the perforated units only being able to take place when the round rod is fastened to the lower part again in its starting position.
  • the punch units have an upper end stop for the punch under spring pressure, which ensures that the Perforated units can be handled as such without the risk of them falling apart.
  • the upper end position of the punch within the punch is not defined by these end stops, but by an end stop of the pressure element, which is thus held in its upper stop position under the action of the prestressed return springs.
  • the hole units are also pretensioned by their return springs, so that either a high level of friction has to be overcome when adjusting the distance or the respective return spring has to be relieved by pressing down the hole die or the spring by hand.
  • the invention is based on the object of improving the known perforator of the type specified at the outset in such a way that the assembled perforated units are easier to move and easier to replace.
  • the solution according to the invention is based on the knowledge that the displacement and replacement of the punching units is facilitated by the fact that the punching units are relieved of the action of the printing mechanism in the upper end position of their punching dies and that the mounting element and the punching die units are as in them Entire one-piece assembly are interchangeable.
  • the punch in its upper end position under the action of its return springs against an upper end stop of the respective punch unit suggest that the pressure element can be lifted up from the rear end faces of the punch in its upper end position to form a free space and that when the pressure element is lifted off the mounting element can be removed from the lower part together with the hole units lined up on it.
  • At least one spring element bridging the perforated units is arranged between the lower part of the punch and the pressure element, which preferably has a support spring which lifts the pressure element from the rear end faces and holds it under pretension against an upper end stop. Since the spring element only has to raise the weight of the pressure element in the end position, the spring forces of the support spring can be selected to be smaller than the rectified spring forces of the return springs of the hole units.
  • the spring element has a plunger which can be displaced vertically to a limited extent parallel to the punches on the lower part and which, under the action of the support spring, preferably designed as a helical compression spring, rests with its upper end face against the pressure element. Deviating from this, the spring element can also be formed by at least one compression or torsion spring arranged between a side cheek of the lower part and the pressure element.
  • the elongated mounting element as Profile or Mehrka ⁇ tstange is formed, on which the hole units are preferably clamped at any distance from each other by means of clamping screws and which in turn is releasably clamped or latched on the lower part.
  • the profile or polygonal rod can consist either of drawn or extruded metal rod or advantageously as an injection molded part made of glass fiber reinforced plastic.
  • a preferably eccentrically arranged or integrally formed, a suitably open, upwardly open recess for receiving the profile or polygonal rod, and a clamping element engaging in the recess carrying clamp holder is provided, the clamping element expediently as in a set screw guided screw is formed.
  • the clamp holder can be integrally connected to a holder for the spring element, which in turn can have a thrust guide for the aforementioned plunger.
  • a further expedient embodiment of the invention provides that the pressure element is mounted or guided on the side cheeks which laterally delimit the lower part and that vertically projecting support faces on the mutually facing inner surfaces of the side cheeks which correspond to the length of the profile or polygonal bar. or guide surfaces for the free ends of the profile or polygonal rod are arranged.
  • the support or guide surfaces are expediently aligned with a vertical and a lower horizontal boundary surface of the open-edge recess of the clamp holder.

  • FIG. 2 shows a rear side view of the multiple punch in a partially broken diagram
  • Fig. 3 shows the lower part of the punch with a set of punch units in a diagrammatic exploded view.
  • the multiple hole punch shown in the drawing essentially consists of a lower part 10 which can be set up on a base, a pressure lever 18 which is pivotably mounted on side walls 12 of the lower part 10 about a horizontal axis 14 and has a handle 16, several at adjustable intervals perforated units 20 arranged on one another on the lower part 10, a scale support 24, which is arranged in an elongated open edge 22 of the lower part 10 so as to be rotatable about its longitudinal axis, and a stop rail 30, which is longitudinally displaceable in a laterally open recess 26 of the lower part 10 and has a side stop 28 for the documents.

Abstract

La présente invention concerne une perforatrice comportant un socle (10), au moins deux unités de perforation (20) à distance réglable sur une barre (34), et un levier de pression (18) pivotant fixé au socle (10) et agissant sur l'arrière (54) des poinçons (56) des unités de perforation (20) pour déplacer les poinçons (56) en opposition à la force d'un ressort de rappel correspondant (48). Pour faciliter le déplacement des unités de perforation (20) à l'intérieur de la perforatrice et ainsi que le remplacement de la barre de montage (34) équipée des unités de perforation (20), les poinçons (56) sont bloqués en position finale haute sous l'action du ressort de rappel (48) contre une butée supérieure (52) de l'unité de perforation qui leur correspond (20), tandis qu'entre le socle (10) et le levier de pression (18) se trouve au moins un élément à ressort (60, 62) qui fait le joint entre les unités de perforation (20) et soulève le levier de pression (18) de l'arrière (54) des poinçons (56) en le maintenant sous précontrainte contre une butée supérieure. On peut ainsi enlever la barre de montage (34) du socle (10) en même temps que les unités de perforation (20) alignées sur elle, sous forme d'unité modulaire.
