Definitions

  • the invention relates to a letter punch with a lower part, a pivotally mounted on lateral bearing blocks of the lower part, guided on the lower part against the restoring force of a spring acting pressure lever and a stop shoulder arranged on the lower part or on the bearing blocks, against which a Pressure lever arranged stop member strikes under the action of the restoring force of the spring.
  • the stop members In known letter holes of this type, the stop members have the function of end stops for the pressure lever in the non-actuated and actuated state. On the other hand, it is desirable, particularly in the case of letter holes with protruding pressure levers, for example for transport and storage purposes, to lock the pressure lever in a depressed position. Hold-down devices made of wood or plastic are mostly used for transport purposes and are thrown away after use.
  • 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 of the pressure lever between two end positions and which forms a hold-down stop against the stop shoulder in the end position when the pressure lever is depressed and in the other Endstellu ⁇ g releases the pivot path of the pressure lever.
  • an actuating head is formed on the slide with a neck part which extends through the elongated hole which extends transversely in the pressure lever and which has projections which overlap the longitudinal side wheels of the elongated hole and which advantageously has its projections which are aligned in the course of the assembly in the longitudinal direction of the elongated hole can be inserted through the elongated hole and can be snapped together with the slider in a slide guide aligned parallel to the elongated hole on the pressure lever by rotating the slide by 90 °.
  • the pressure lever advantageously has two guide ribs which are arranged at a distance from one another and are aligned 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 stop edge one of the guide ribs of the pressure lever guided 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 which is 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 ⁇ releasing the pivoting path of the pressure lever to a latching organ of the pressure lever.
  • the stop edge of the slide is advantageously set in a wedge shape with respect 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 Gege ⁇ rastorga ⁇ for the latching tongue are expediently arranged in the region of an apron which delimits the pressure lever at the end downwards.
  • Figure 1 shows a letter punch with hold-down device in a diagram.
  • FIG. 2 shows a partially sectioned lateral outline of the punch according to FIG. 1 in the hold-down position
  • Fig. 4 is a side view of the hold-down slide according to Fig. 3;
  • FIG. 5 shows an end view of the hold-down slide according to FIGS. 3 'and 4.
  • the cast hole punch shown in FIGS. 1 and 2 essentially consists of a punch lower part 10, two bearing blocks 14 arranged laterally on the lower part 10 and a pressure lever 18 which can be pivoted on the bearing blocks about a pivot axis 16.
  • the pressure lever 18 has two laterally downwards curved bearing tabs 20 which overlap the bearing blocks 14 on the outside, and an apron 22 which is bent downward on the end face and connects the bearing tabs to one another.
  • upwardly facing cantilevers 24 are formed, which reach under the apron 22 of the pressure lever and against whose upper edge, which forms a stop shoulder 26, a stop rib 30 un projecting inward on the pressure lever 18 and designed as an end stop ⁇ ter of the action of the spring 28 strikes.
  • a slider in the region 22 of the pressure lever 32, a slider arranged transversely of and "an operating head extends with a neck portion 33 34 through an elongated hole 36 in the skirt 22 to the front hin ⁇ .
  • the slide 32 which is designed as an injection-molded part made of plastic, is made with its actuating head 34 in the longitudinal direction of the elongated hole 36 directed projections 38 inserted through the La ⁇ gloch 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 skirt.
  • the lower guide edge 40 is inclined relative to the slide plane. Adjacent to it is a stop edge 48 which is inclined on 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 rib 30 for the slide 32 at the same time forms the end stop which abuts against the stop shoulder 26 of the arm 24.
  • a locking tongue 50 which chlagwolf from the Ans' out ge Wegten end position of the slide in an unillustrated mating catch on the pressure lever engages with a Rastor ⁇ gan 52 extends.

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).
