Definitions

  • the invention relates to a plastic staple with two outer approximately V-shaped clamping legs, which are connected via crossbars with two parallel, separated by a slot clamping sections, at the ends of a connecting plate is arranged, the two V-shaped spreading clamp arms having.
  • a plastic staple of this type is already known (DE-PS 20 37 708).
  • the main task for her is to create a staple that can be used for very thick stacks of sheets.
  • the longitudinal slot extends over a little more than half the length of the staple and extends practically to the connection point between the connection plate and the inner clamping arms.
  • this is not desirable.
  • the invention has for its object to provide a staple, in particular a staple of the type mentioned, which can be produced by injection molding with economic effort and in which a high clamping force is achieved even with a small thickness of the paper stack.
  • the invention provides that in a staple the longitudinal slot extends at most over about a third of the length of the clip, the clamping sections are connected to the connecting plate via an extension section which is longer than wide, and the space between the extension element and the clamping arms is designed as a slot with an at least partially oblique longitudinal direction.
  • the inner portion In order for staples to do their job properly, it is common for the inner portion to span approximately two thirds to three quarters of the length of the entire staple.
  • the shortening of the slot does not change the length of the inner clamping section, but the clamping force that can be achieved is greater.
  • the clamping force is essentially achieved by the torsion of the two longitudinally extending clamping sections.
  • the shortening of the longitudinal slot leads to a shortening of the clamping sections subjected to torsion and thereby to an increase in the clamping force.
  • the lateral slots have essentially parallel side edges. So they have the same width everywhere.
  • the clamping arms also have parallel side edges.
  • the clamping arms had a slightly converging shape with a decreasing thickness.
  • clamping arms run parallel to the outer clamping legs.
  • the staple shown in Fig. 1 for stapling at least two sheets of paper to one another contains two outer clamping legs 11 which are approximately V-shaped spread out.
  • the clamping legs 11 are connected to one another by a rounded arch 13.
  • the outer clamping limbs 11 merge into a transverse web 14, which runs perpendicular to the longitudinal direction of the staple.
  • the longitudinal direction of the staple is also the bisector between the two straight outer clamping legs 11, this bisector also forming a line of symmetry for the staple.
  • the transverse webs 14 merge into a clamping section 15.
  • clamping sections 15 in turn run perpendicular to the transverse webs into the interior of the clip, ie inside the outer clamping legs 11.
  • the clamping sections 15 run parallel to one another and to the line of symmetry of the staple. They are separated from each other by a longitudinal slot 16, which has the same width everywhere in the illustrated embodiment.
  • the longitudinal slot 16 has a length 17 which is approximately 30% of the total length of the staple. The longitudinal slot 16 enables the two crossbars to be twisted out of the plane of the paper when two sheets of paper are clamped together, which leads to a torsion of the clamping sections 15.
  • the clamping webs 15 merge into a slightly converging extension element 19 which is delimited on both sides by obliquely running slots 20.
  • the extension element 19 merges into a connecting plate 22, the lower end 23 of which is rounded in an arc.
  • the distance from the upper edge of the staple to the lower end 23 of the connecting plate 22 corresponds to approximately two thirds to three quarters of the total length of the staple.
  • Clamping arms 24 are formed on both sides of the connecting plate, which arms have the same width throughout and extend into the space between the extension plate 19 or the clamping sections 15 and the outer clamping legs 11. They run parallel to the outer clamp legs 11, wherein between their outer edges and the clamping legs 11 an equally wide space is formed everywhere.
  • the profile of the clip has a flat top 25 and a flat bottom 26.
  • the side walls 27 and 28 of the profile are designed to be slightly converging, the angle seen in FIG. 2 being around 150 °.
  • a cross section through the other parts of the staple is formed.
