  • this extension direction Z runs at an angle ⁇ of 38 ° with respect to a perpendicular to the step plate plane 13.
  • the edge strip 3 is provided with the same rib division as the tread plate 2, with mutual locking the ribs 14 of the edge strip 3 with the ribs 15 of the tread plate 2, part of the ribs 14 of the edge strip 3 are provided on their sides adjacent to the ribs 15 of the tread plate 2 with guide grooves 16, into each of which a guide comb 17 of the adjacent ribs of the adjacent ribs is arranged Step plate 2 engages.
  • the guide combs 17 are open on their lower end faces 18.
  • the two lateral edge strips 4 and 5 are provided on their underside with a plurality of springs 19 which are distributed over their length and extend in their transverse direction, the cross sections of which are analogous to the springs 6 and 7 of the rear edge strip 3 have the shape of a parallelogram with mutually identical angles and engage in corresponding grooves 20 in the step plate 2 in the manner of a tongue and groove connection.
  • These two side edge strips 4 and 5 are, similarly to the rear edge strip 3, also provided on their underside on their underside with two guide and locking bolts 10, which are distributed over their length and extend downwards and through the adjoining tread plate 2, at the bottom thereof from the tread plate 2 protruding free ends analogous to the rear edge 3 each a clamping ring 11 which is supported under spring pressure on the underside of the tread plate 2 is clamped.
  • the guide and locking bolts 10, the guide and passage openings 12 assigned to them and the tongue and groove connections 19, 20 are coordinated with one another analogously to the rear edge strip 3 in such a way that they allow the springs 19 of the two edge strips 4 and 5 in to be retracted freely allow the grooves 20 associated with these springs 19 in the tread plate 2.
  • the insertion direction Z of the tongue and groove connection 19, 20 and the guide and locking bolt 10 is the same as for the rear edge strip 3 already described above for the simplest possible production.
  • edge strips 3, 4 and 5 are extremely simple, since they are simply inserted obliquely into the tread plate 2 and then the clamping rings 11 onto the free ends of the guide and locking bolts which are inserted in the tread plate 2 and protrude from the underside of the tread plate 2 10 can be pressed.
  • the clamping rings 11 are made of spring steel and have a cambered design, so that they can be pressed onto the slightly conical locking bolts 10 in a simple manner up to the resilient contact on the underside of the tread plate 2 and then there automatically on the latter clamp. Slightly cambered spring washers or disc springs as well as so-called Schnorr rib washers can also be used as clamping rings 11.
  • the grooves 19 'and the springs 20' are provided with a dovetail cross section.
  • edge strips 4 ', 5' can be pushed into each other because of the shape of the grooves 19 'and the springs 19' only in the lateral direction of these edge strips 4 ', 5'.
