Definitions

  • the present invention relates to a paper punch according to the preamble of the main claim.
  • Paper punches with which file parts are punched for filing are known in a wide variety of designs. Small punches are described in pocket foams (DE-OS 28 41 441; DE-OS 22 10 794; DE-GM 73 07 954), which only have a punch and a punch hole with which the paper to be punched is punched in the folded state , which results in two perforations.
  • the problem with these punches is that the punch tilts in the punching hole because it moves in a circular path during the punching process.
  • the object of the present invention is to propose a punch which, both in the design as a small pocket punch with only one punch and in the usual office punch design, enables the punch to be guided precisely to the punch hole in a simple manner and without complex construction.
  • the invention can also be used for punches with more than two punching dies, such as those used for punches of so-called ring binder inserts which cause more than two perforations, for example three or four.
  • At least one of the legs on which the punch or the punching hole is arranged is designed as a hollow profile with a rectangular cross-section, then when the hollow profile is elastically deformed, for example when the longer edges of the rectangular profile are bent, the outer shorter edge of the Rectangular profiles moved parallel to the second, shorter edge of the rectangular profile, so that there is no canting of the punch located in the area of the outer edge. It is not necessary for the entire leg to be designed as a hollow profile. It is sufficient if a longer section is designed accordingly
  • both legs are designed as hollow profiles.
  • the invention enables the creation of perforations which consist only of two elastic, interconnected legs, on which one or more punches and the corresponding punch holes are arranged. A lever or spring mechanism is no longer required.
  • Figure la shows a small hole punch with a punch in a sectional view from the side
  • Figure lb shows the same hole in the same section in the pressed state pressed
  • Figure lc shows the same hole in a view from below
  • Figure 2a shows an office punch with two punches in a view from below
  • Figure 2b shows the same punch in a sectional view from the side.
  • the punch of Figures la to lc contains a punch 14 from a round pin sharpened at the edges, which is arranged in a shorter boundary wall 24 of a hollow profile 20, which forms a first leg 10 of the punch.
  • the first leg 10 is connected by a connecting part 26, for example in the form of a pin, to a second leg 12, which is also formed from a hollow profile 20.
  • Both hollow profiles 20 consist of a resilient plastic which is referred to as the punching direction S in the direction in which both legs can be moved towards one another due to their elasticity.
  • the punch 14 is inserted into the punch hole 16, which causes the punching process.
  • Figure la shows the punch in the initial state, Figure lb in the compressed state in which the punching process is finished.
  • FIGS. 2a and 2b show a further embodiment as an office punch, with which two punch openings can be produced in a sheet in a conventional manner. This embodiment is obtained by doubling the functional elements of the embodiment of FIGS. 1a-c.
  • the reference numerals correspond to one another in the illustration.
  • FIGS. 1 a, 1 b and 2 b it can be seen from FIGS. 1 a, 1 b and 2 b that the entire extension of the legs 10, 12 need not be designed as hollow profiles. Rather, the end parts, in particular. H. the shorter boundary walls of the hollow profiles 20 have a solid design in order to facilitate the attachment of the punch 14, punch hole 16 and connecting part 26.
