Definitions

  • the invention relates to a punching device for simultaneously punching at least two holes in paper, comprising a housing with a base, a rocker pivotally mounted in the housing with a tactile surface, at least two punching bolts actuated by the rocker, each with an associated bushing, and an approximately perpendicular to the Stand slot arranged for insertion of the paper.
  • Punchers of this type are already known (DE-C-722500, FR-A-1 431 020) in which the paper to be punched is inserted from above into a slot arranged perpendicular to the base. Since the rectilinear slot for punching paper has only a relatively small depth, the paper introduced into the slot tends to tip over the edge of the slot and must therefore be held in position by large, obliquely upward-facing contact plates.
  • the object of the invention is to provide a perforating apparatus of the type specified at the outset, in which the paper inserted into the vertical slot remains in a vertical position by itself.
  • the curved arrangement of the slot prevents the inserted paper from tipping over over the edge of the slot, thereby considerably simplifying the one-handed operation of the apparatus.
  • the perforated apparatus shown has a housing consisting of an upper part 1 and a lower part 2.
  • Four rubber feet 6 with an adhesive surface inserted in the frame 2 in frames 26 form a base 9 and prevent them from slipping even on a smooth surface.
  • a slot 11 with an insertion 12 for the paper is directed upwards in the upper part 1, that is to say it is arranged perpendicular to the base 9 and is thus clearly visible.
  • punching several sheets at the same time they do not have to be bundled first; this happens automatically with vertical feeding due to the gravity of the paper on the slot bottom 13.
  • the slot 11 is curved. This has the advantage that the inserted paper sheet does not tip over backwards and forwards. This makes it much easier to operate the device with one hand.
  • a paper pressure spring 24 prevents the sheet from tipping over if more than half of its length protrudes laterally from the slot 12.
  • the dome-shaped shape of the pressure spring surface 25 facilitates paper insertion.
  • a cylindrical pin 35 of a rocker 3 designed as an angle lever 32 is mounted in semicircular recesses in the lower part 2 designed as a bearing 22.
  • the pin 35 is held in the bearings 22 by a spring 16 integral with the upper part 1.
  • One leg of the rocker 3 has a tactile surface 31 protruding from the upper part 1.
  • the other leg engages with a slot 36 in a circumferential groove of two metal punching bolts 7, which are each slidably mounted in a bearing 27 in the lower part 2.
  • the punching waste can also be emptied into small containers in a very targeted manner, in that the laterally attached lid 5 is moved upward, so that the waste channel 15 is released.
  • the lid guide 17 is limited at the top so that the lid 5 cannot be lost.
  • the overload protection formed by the bearings 22 and the spring 16 prevents possible damage to the apparatus as follows: If the force applied to the touch surface 31 is greater than the permissible, the rocker 3 jumps out of the bearings 22 with its pin 35 Punching pin 7 in the normal position happens in that a cylindrical object, for. B. a pencil, passed through a hole 23 in the lower part 2 and this is reset by pressing the inner surface 34 of the rocker 3 upwards.
  • the apparatus has four sliding buttons 4 for setting the format sizes to be punched, A4, A5 and A6.
  • buttons 4 By moving the button 4 in the direction of the arrow, a stop 41 for the paper sheets, which is clearly visible from above, is pushed into a recess 14.
  • A4 format two holes can be punched in the middle when the outermost button 43 is pressed, or four holes when the innermost button 42 is pressed, by turning the page after the first punching process and the rocker 3 is operated again.
  • the number of holes is marked by understandable symbols 44 on the individual sliding buttons 4.
  • the 4 buttons are automatically reset when the format setting is changed.
  • the apparatus can be assembled without special auxiliary tools.
  • the procedure is as follows: Four self-adhesive rubber feet 6 are applied to the frame 26 on the underside of the lower part 2.
  • the rocker 3 is inserted with its round pin 35 into the bearing 22.
  • Two punch bolts 7 are brought into engagement with the slots 36 of the angle lever 32 and snapped into their bearing points 27.
  • the two sleeves 8 are also snapped into the recesses 28 on the same axis as the punch bolts 7.
  • the one-piece component consisting of the sliding buttons 4, the spring struts 47, the cams 45 and the stops 41 is inserted into the lower part 2 in such a way that the four adjustable stops 41 are mounted in their guide grooves 29 arranged in pairs.
  • the struts 47 rest against ribs 30.
  • the cover 5 is inserted laterally into the T-groove of the upper housing part 1.
  • the upper housing part 1 is non-releasably connected to the latter by means of snap arms 20 which are molded onto the lower part
  • the described simple and inexpensive to produce button arrangement can also be used in devices other than punches, for. B. for selector switches in electrical devices.
  • one of the keys can easily be designed as a pure reset key, in that its cam 45 is formed so long that it does not snap into the associated catch 46.
  • the overload protection described is also generally applicable to swivel levers.
