Definitions

  • the invention relates to a letter punch with a lower part, a pivotally mounted punch on the lateral bearing blocks of the lower part and guided on the lower part against the restoring force of a spring acting pressure lever, the pressure lever being bent laterally downwards and the bearing blocks on the outside has overlapping bearing tabs and an apron on the end face of the pressure lever in the area between the bearing tabs which is bent downwards and strikes the bearing blocks under the action of the restoring force of the spring against stop edges.
  • the invention is based on the object, the known letter punch of the initially mentioned * to improve the above-mentioned type in such a way that a risk of injury is avoided even if the letter punch is improperly handled.
  • the solution according to the invention is based on the knowledge that when the pressure lever is actuated, no gap which is accessible from the outside may occur, into which hand parts can inadvertently penetrate, even when handled improperly.
  • the stop edges are arranged on thin-walled cantilevers of the bearing blocks that are aligned parallel to the bearing tabs, and that the apron has a bend on its side edges near its lower edge, which together with the adjacent bearing tab, a gap open towards the lower part for the engagement of the boom is limited.
  • the stop edge can either be formed by an upward-facing step which abuts an upper limit edge of the gap, which is preferably arranged on the apron, or by a front edge of the arm which strikes the apron on the back in the region near the gap.
  • apron on the bearing blocks are arranged cantilever arms which face upwards and underneath the apron, the upper edges of which Form beating edges, while the apron has at the distance from its lower edge protruding stops on the back for the upper edges of the brackets.
  • the arrangement of the stops provided according to the second variant of the invention makes it possible, in the area between the lower edge of the skirt and the stops, to be displaced transversely on the skirt between two end positions and, in one end position, engaging in the welding path of one of the upper boom edges, as low ⁇ holder for the pressure lever trained stopper to arrange.
  • the stop slide can be locked at least in a latching connection at least in the end position disengaged from the pivoting path of the boom on the pressure lever.
  • the stop slide is advantageously guided in a substantially horizontal hole in the apron and has an actuating head extending through the elongated hole to the end face of the punch.
  • the distance between the apron and a crossbeam which hides the punch on the end face is chosen to be at least finger width over the entire pivoting range of the pressure lever. This ensures that accidental pinching of hand parts is avoided in this area as well.
  • FIG. 2 shows a vertical section through the sheet metal punch according to FIG. 1;
  • FIG. 4 shows a vertical section through the cast hole punch according to FIG. 3.
  • the sheet metal punch shown in FIGS. 1 and 2 essentially consists of a lower part 10, a bearing part 12 rigidly connected to the lower part and an on the bearing blocks 14 of the bearing part 12 about an axis 16 pivotally mounted pressure lever 18.
  • each punch 22 which presses down the pressure lever 18 while penetrating the insertion slot 24 and a die opening 26 in the lower part 10 against the restoring force the springs 20 are moved down.
  • the pressure lever is automatically pivoted back into its starting position under the action of the springs 20.
  • the pressure lever 18 has two bearing tabs 28 bent laterally downwards, which overlap the bearing blocks 14 on the outside. Furthermore, the pressure lever 18 is provided with a stop apron 30 which is bent downward at the end face and connects the two bearing tabs 28 to one another. In the vicinity of its side edges and in the area of its lower edge 32, the apron 30 has a flap-like bend 34 pointing backwards, which together with the adjacent bearing flap 28 has a downwardly open edge and is closed at the top by a punched edge 36 in the apron Gap 38 limited.
  • a thin-walled arm 40 of the bearing block 14 engages in this gap and has a step 42 serving as a stop for the transverse edge 36 arranged on the skirt 30.
  • step 42 an edge part of the arm 40 which extends below the apron 30 serves as a stop for the pressure lever. Since the width of the gap 38 can be made smaller than 4 mm, there is no danger that a finger is pinched between the stop edges. It is only important that the bend 34 is so long that the boom 40 still engages in the gap 38 even when the pressure lever 18 is depressed.
  • the punch guides in the bearing part 12 are concealed at the end face by a crossbeam 43.
  • the apron 30 and the crossbar 43 are at least a finger-wide apart from one another in all swivel positions of the pressure lever 18.
  • the lower part 10 and the bearing blocks 14 are integrally connected to one another with the insertion slot 24 being released.
  • the arms 50 have a part-cylindrical curvature to the pivot axis 16 in their part which engages under the skirt 30, while the skirt 30 on its side facing the arms 50 is formed accordingly bowl-shaped.
  • the described arrangement of the stops of the cast hole punch according to FIGS. 3 and 4 is also suitable for accommodating an adjustable type impact slide 56 in the area between the lower skirt edge 32 and one of the stop cams 54.
  • a stop slide 56 which is located in a horizontal slot 58 of the Apron 30 is arranged to be displaceable and serves as a hold-down device for the pressure lever 18, which can be brought into engagement with the adjacent upper edge 52 of the jib, for example for transport or storage purposes.
  • the stop slide 56 should preferably be lockable in a latching connection at least in the end position disengaged from the pivoting path of the boom 50 on the pressure lever 18.

Abstract

Un perforateur comprend une base (10) et un levier de compression (18) monté de manière pivotable sur des paliers latéraux de support (14) de la base qui agit contre la force de rappel d'un ressort (20) sur des poinçons perforateurs (22) guidés de manière mobile sur la base. Le levier de compression (18) comprend deux oreilles de support (28) latérales, recourbées vers le bas, qui recouvrent la face extérieure des paliers de support (14), et une jupe (30) recourbée vers le bas, agencée du côté frontal du levier de compression (18), entre les oreilles de support, qui s'appuie sur des rebords d'arrêt des paliers de support (14) sous l'effet de la force de rappel des ressorts (20). Afin de prévenir des risques de blessures par serrage de parties de la main, les rebords d'arrêt sont agencés sur des bras (40) des paliers de support (14) parallèles aux oreilles de support (28) et ayant des parois minces, alors que la jupe (30) comprend une partie repliée sur ses bords latéraux, à proximité de son rebord inférieur. Cette partie repliée délimite avec l'oreille adjacente de support (28) une fente (38) étroite, marginalement ouverte du côté de la base, dans laquelle pénètre le bras (40).
