Definitions

  • the invention relates to a single letter punch, which, in the absence of a conventional letter punch, can be used for punching documents, for example at meetings or when traveling, and has the advantage of very small dimensions.
  • the hold-down rail of a letter folder with its swivel-mounted rocker is suitable for the formation of a multi-purpose device cf. DE-A-2 907 718.
  • a hold-down rail according to the teaching of DE-A-2 319 904 is particularly suitable for this because the rocker of this hold-down rail lies relatively flat on the base plate of the hold-down rail even in the released state and thus also for itself alone in a flat file, against the back fold, can be stored without spreading the front cover.
  • a hold-down rail of this type is also suitable for training as a multipurpose device because the rocker is mounted without play in the longitudinal direction of the base plate.
  • the double function of a hold-down rail is achieved according to the invention in that it has the features of claim 1.
  • the distance of the punch formed on the rocker from the expanding cams acting on the longitudinal spring wires or from the clamping tongues acting on the longitudinal spring wires is dimensioned such that the expanding cam or the clamping tongues can serve as a stop for the documents to be punched and thus a predetermined edge strip width is guaranteed.
  • the hold-down rail which can be used as a single letter punch advantageously has the features which form the characterizing part of patent claims 3 and 4.
  • the base plate 1 of the hold-down rail has two openings 11 through which the bearing tongues 21 of the rocker 2 extend. In its central region, the base plate 1 has two cutouts 12 through which the two clamping tongues 22 acting on the longitudinal spring wires 3 extend. Adjacent to the openings 13 for the aligning pins of a aligning device, holders 14 are provided for the longitudinal spring wires 3.
  • the circular opening 15 of the base plate 1 forms the cutting die, into which the punch 23 formed on the rocker 2 engages.
  • a notch 24 is provided on the rocker as a center indicator.
