Definitions

  • the invention relates to a single-hole punch with a Base plate and two arranged on the base plate Bearing blocks to accommodate one against the restoring force a spring pivotally mounted pressure lever, wherein the pressure lever against a vertically guided punch acts and between the base plate and the A paper insertion gap is formed in the bearing blocks by an upward cranking of the base plate has rear stop and with a central Mark on the front of the pressure lever is.
  • the invention has for its object a known Form single-hole punches so that any multiple perforations can be produced exactly at the desired intervals are.
  • This task is accomplished according to the invention by the assignment an additional sighting device for fixing the intended perforations solved, the sighting device in the functional state before or in the area of the insertion gap ends and through a visor fork can be formed.
  • the sighting device in the functional state before or in the area of the insertion gap ends and through a visor fork can be formed.
  • the visor fork Made of a clear material and has two parallel ends Thighs, both on a flat Section are connected. There is a possibility one at the free end of the flat section Arrange the top edge of the handle, which is rounded can be.
  • the visor fork is provided with locking cams, which Corresponding rest recordings are assigned.
  • the known single-hole punches have a base plate 1 and two fixedly arranged on the base plate 1 Bearing blocks 2, which for structural reasons have a Base plate are integrally molded.
  • the bearing bracket 2 serve to take up a against the restoring force a spring pivotally mounted pressure lever 3, the acts against a vertically guided punch. Is between the base plate 1 and the pedestals 2 a paper insertion nip 4 formed by one an upper cranking of the bottom plate 1 is formed has rear stop 5.
  • a sighting device in the form of a sighting fork 6 assigned.
  • This visor fork 6 can after Figure 1 displaceable between the two bearing blocks 2 stored or according to Figure 4 at the front boundary of the pressure lever 3 fixedly arranged via an angle 10 be. As FIG. 4 shows, the visor fork is 6 closed at the front free end and thus a Elongated hole 11 formed.
  • the inserted between the two bearing bracket 2 Virsiergabel 6, which advantageously consists of a transparent Material is formed, has two parallel Leg 7 on, both on a flat Section 8 are connected.
  • For better handling is at the free end of the flat section 8 after Shaped rounded handle 9 above.
  • the behavior Lengths of the legs 7 and the length of the flat section 8 approximately as 3: 1, the leg 7 and the flat section 8 have identical thickness.
  • the sheet 14 to be punched is placed under the sample sheet 12 with the already existing perforations 13 so that the area to be punched outside the Pattern sheet 12 lies.
  • the one on the one-hole punch Visor fork 6 is placed exactly on an existing hole 13 placed so that the new hole made exactly can be.
