Definitions

  • the invention relates to a ladder with two spars and rungs used in them, the spars being designed as hollow supports and the ends of the rungs being inserted into the spars with openings in them and being held there in a form-fitting manner.
  • a ladder is known, the rungs of which are fastened in the spars in such a way that they can no longer be removed therefrom (CH-PS 629 568).
  • each end of a rung is supported in an insert made of elastic material, which is anchored in the interior of the spar and has further anchoring cams which engage in bores in depressions arranged in the ends of the rungs.
  • the ends are inserted with slight deformation of the insert and are then no longer detachable.
  • the end of the rung can only be released from the insert inserted in the stiles by destroying the stile.
  • At least one rung of the ladder is made of a transparent plastic, the ends of which are inserted non-detachably in the two spars. Because the rung is made of a transparent material, the marking can be moved into the rung, from which it can then only be removed by destroying the rung.
  • the rung is expediently designed as a hollow body, the rung being designed as a polygonal, for example square, hollow body as a preferred embodiment.
  • the hollow body shape of the rung makes it possible to insert a marking, for example a name or a color picture, in the cavity of the rung, which can then no longer be removed without destroying the ladder.
  • the walls of the hollow body are expediently made transparent, with a reinforcement, for example a glass fiber strand, being embedded in the corners of the polygon shape.
  • the ladder shown in FIG. 1 has two bars 1, which are connected to one another by rungs 2.
  • the length of the ladder or the possibility of folding the ladder into a fixed ladder can be realized in any way.
  • At least one rung 22 is made of a transparent plastic.
  • a transparent polyvinyl chloride (PVC) can be used, which has a high hardness and a high toughness.
  • FIG. 2 and 3 show the details of the design of the rung 22 and its connection to the spar 1, FIG. 2 showing the connection of one end 21 of the rung 22 to the spar 1, while in FIG. 3 the design of the rung 22 is shown in detail.
  • the insert body 5 has a cylindrical body 6, which corresponds to the square cross-sectional shape of the rung 22 is a square cylinder.
  • a flange 7 adjoins one end of the cylindrical body 6, while the cylindrical body 6 is closed off by a base 8 at the other end.
  • the bottom 8 has an outwardly protruding pin 9 with a thickening 10 which extends through a bore 30 in the wall 25 of the spar 1.
  • the base 8 is held in the bore 30 in a form-fitting manner by the thickening 10.
  • the spar 1 is designed as a rectangular hollow body whose wall opposite the wall 25 has a corresponding square opening 26 for receiving the insert 5.
  • the walls 12 of the cylindrical body 6 have slot parts 13, from which ribs 14 protrude. If the insert 5 with the end 21 of the rung 22 is inserted through the opening 26 in the wall 11 of the spar 1, the ribs 14 protrude so that the insert 5 can no longer be removed from the opening 26. Together with the thickening 10, the ribs 14 form a no longer detachable mounting of the insert 5 in the spar 1.
  • a pin 16 is integrally formed on at least two side walls 11 of the cylindrical body 6 and engages in a bore 19 in the wall of the rung 22 when the end 21 is inserted into the insert.
  • the rung 22, see FIG. 3, is a square body, the walls 27 of which are transparent. So that there is no risk of slipping, the outside of a wall 27 can be provided with grooves 28. However, these grooves do not affect the transparency of the wall 27.
  • Fig. 3 From Fig. 3 it can be seen that 22 reinforcements 23 are embedded in the corners of the rung.
  • This reinforcement can consist of glass fibers, for example, which extend over the length of the rung.
  • the rung 22 is given additional strength so that it can support large weights without problems and can be derived from the bars 1.
  • the interior 29 of the rung 22 can now be used to insert a label which, because of the described anchoring between rung 22 and spar 1, is not accessible without destroying a part.
  • an insert sheet 24 can be inserted into the interior 29, which is marked with a label, e.g. with a font, a coloring or the like. is provided.
  • the insert sheet 24 is inserted into the interior 29 of the rung 22 and, since the rung walls 27 are transparent, is clearly visible. In this case, it is expedient to design the insert sheet 24 in such a way that it can be snugly inserted into the interior 29 so that it can no longer move.
  • the transparent rung 22 also has the same strength as the other rungs 2, which consist, for example, of a solid artificial rod.
