Definitions

  • the invention relates to a simple letter punch simple and space-saving design, which causes only low manufacturing costs and can be conveniently accommodated in a briefcase or the like.
  • the production of the letter punch causes especially very low costs because the letter punch consists practically only of two parts, the housing preferably made of plastic and the metal punch that can be used in it, so that no special devices are required for mounting the letter punch.
  • the punch according to the invention has the in claim 1 given and advantageously on the features specified in the dependent claims.
  • Adequate springing of the plate covering the housing at the top can be achieved by a tapering of the material or also in that only a central part of the cover plate delimited by two cuts engages the punch and is designed as a resilient tongue.
  • the punch stroke is determined by the distance of the resilient cover plate or of the resilient cover plate from the part of the part of the housing forming the guide of the punch, and thus limited, so that excessive stress on the cover plate is avoided.
  • the preferably made of plastic body of the punch hole has a chip chamber 1 enclosed by four side walls, the upper end of which forms the matrix web 2.
  • the insertion slot is delimited on its upper side by a cantilever arm 4 which forms the guide for the punch 3.
  • the punch 3 has a widened head 31 serving as a pushbutton and underneath this an annular groove 32, in which the front plate-shaped cover plate 5 engages.
  • the chip chamber 1 has a recess in a side wall or in the base plate, which is closed by means of a removable plate.
