Definitions

  • the invention relates to a letter punch with a lower part, a pivotally mounted on lateral bearing blocks of the lower part, which is guided on the lower part displaceably guided against the restoring force of a spring pressure lever and a stop shoulder arranged on the lower part or on the bearing blocks, against which an arranged on the pressure lever stop member below the action of the restoring force of the spring.
  • Such a letter punch is e.g. through delivery and use by customers of the specialist world from the priority date of this patent application.
  • the stop members have the function of end stops for the pressure lever in the non-actuated and actuated state.
  • the invention has for its object to provide a letter punch of the type mentioned, which has an integrated in the hole punch, easy to manufacture and assemble hold-down for the pressure lever.
  • the invention consists essentially in the fact that the stop member is designed as a one-piece slide made of plastic which can be displaced in an elongated hole in the pressure lever between two end positions and which forms a hold-down stop against the stop shoulder in the one end position when the pressure lever is depressed and the swivel path of the in the other end position Releases the pressure lever.
  • an actuating head is formed on the slide with a neck part which extends through the elongated hole extending transversely in the pressure lever and which has projections which overlap the longitudinal side edges of the elongated hole and which advantageously has its projections aligned in the course of the assembly in the longitudinal direction of the elongated hole Elongated hole can be inserted and locked by rotating the slide by 90 ° together with the slide in a sliding guide aligned parallel to the elongated hole on the pressure lever.
  • the pressure lever advantageously has two guide ribs which are arranged at a distance from one another and are oriented parallel to the elongated hole and form the sliding guide, while the slide has a stop edge facing the stop shoulder, a wedge-shaped or laterally offset edge against the stop edge and guided on one of the guide ribs of the pressure lever first guide edge and one opposite the stop edge and the first guide edge on the second guide rib of the pressure lever has guided second leading edge.
  • a latching tongue preferably arranged on the side of the second guide edge, can be provided on the slide, with which it can be locked in the end position which releases the pivoting path of the pressure lever on a latching member of the pressure lever.
  • the stop edge of the slide is advantageously wedge-shaped relative to the slide plane, so that the major part of the hold-down forces exerted by the return spring is transmitted to the inside of the pressure lever and not only to the relatively narrow second guide rib.
  • the guide ribs, the elongated hole and the counter-latching element for the latching tongue are expediently arranged in the region of an apron which delimits the pressure lever on the end face at the bottom.
  • the cast hole punch shown in FIGS. 1 and 2 essentially consists of a lower hole part 10, two bearing blocks 14 arranged laterally on the lower part 10 and a pressure lever 18 which can be pivoted to a limited extent on the bearing blocks about a pivot axis 16.
  • the pressure lever 18 has two laterally downwards curved bearing tabs 20 which overlap the outside of the bearing blocks 14 and an apron 22 which is bent downward on the end face and connects the bearing tabs to one another.
  • upward-facing cantilevers 24 are formed, which engage under the apron 22 of the pressure lever and against whose upper edge, which forms a stop shoulder 26, a guide and stop rib 30 which projects inward on the pressure lever 18 and is designed as an end stop, under the action of Spring 28 strikes.
  • a slide 32 is arranged such that it can be displaced transversely, which reaches through to the front with a neck part 33 and an actuating head 34 through an elongated hole 36 in the apron 22.
  • the slide 32 designed as an injection molded part made of plastic is aligned with its actuating head 34 in the longitudinal direction of the elongated hole 36 during assembly Projections 38 inserted through the elongated hole and then rotated by 90 °, so that the projections 38 positively overlap the longitudinal side edges of the elongated hole.
  • the lateral guide edges 40, 42 of the slide 32 snap into the area between the two guide ribs 44, 30 protruding towards the inside of the apron.
  • the lower guide edge 40 is inclined relative to the slide plane. Adjacent to it is a stop edge 48 which is inclined towards the opposite side and which, in engagement with the stop shoulder 26 of the adjacent arm 24, serves as a hold-down stop for the pressure lever 18.
  • the upper guide and deflection rib 30 for the slide 32 also forms the end stop which abuts against the stop shoulder 26 of the arm 24.
  • a latching tongue 50 which engages with a latching member 52 in the end position of the slide moved out of the stop position into a counter-latching, not shown, on the pressure lever.

Abstract

Un perforateur comprend une base (10), un levier de compression (18) monté de manière pivotable sur des paliers latéraux de support de la base (10) qui agit contre la force de rappel d'un ressort (28) sur des poinçons perforateurs guidés de manière coulissante sur la base (10), et un épaulement d'arrêt agencé sur les paliers de support (14) contre lesquels un organe de butée (32) s'arrête sous l'effet de la force de rappel des ressorts (28). L'organe de butée (32) forme une coulisse (32) en plastique en une seule pièce transversalement mobile sur le levier de compression (18) entre deux positions extrêmes. Dans une position extrême, lorsque le levier de compression (18) est abaissé, l'organe de butée forme une butée de retenue du levier en position abaissée contre l'épaulement d'arrêt (26), alors que dans l'autre position extrême, il laisse pivoter librement le levier de compression (18).

Claims (8)

  1. Perforateur comportant un socle (10), un levier de pression (18) monté basculant sur des flasques (14) de ce socle et agissant, contre la force de rappel d'un ressort (28), sur des poinçons montés mobiles sur le socle, et une épaule de butée (26) placée sur le socle ou sur les flasques contre laquelle bute, sous l'action de la force de rappel du ressort (28), un organe de butée (32) prévu sur le levier de pression (18), caractérisé par le fait que l'organe de butée est constitué d'un coulisseau d'une seule pièce (32) en plastique mobile dans un trou allongé (36) entre deux positions extrêmes et qui, dans une de ces positions, lorsque le levier de pression (18) est abaissé, forme une butée de maintien d'abaissement s'appuyant contre l'épaule de butée (26) et, dans l'autre position extrême, dégage la voie de basculement du levier de pression (18).
