Definitions

  • the present invention relates to a stairway.
  • the present invention relates to a stairway of the type comprising a plurality of steps fixed to two side flanks, which are formed of metallic material, extend in corresponding substantially vertical, reciprocally parallel retaining planes, and each comprises at least two corresponding, substantially flat supporting plates, each of which is substantially step-shaped, and is provided with a plurality of reciprocally parallel teeth protruding from the supporting plate itself.
  • each supporting plate slidingly engage corresponding recesses obtained in the other supporting plate so as to reciprocally lock the supporting plates in a second vertical direction orthogonal to the first direction.
  • the supporting plates of each side flank are reciprocally locked in the first direction by means of at least one locking plate arranged in contact with the supporting plates and fixed to the supporting plates themselves by means of fastening screws.
  • the known stairways of the above-described type present some drawbacks, mainly deriving from the fact that the locking of the supporting plates in the first direction implies the use of the mentioned locking plates, a relatively complex structure and assembly of such stairways, and relatively high costs of the stairways themselves.
  • numeral 1 indicates, as a whole, a stairway comprising two side flanks 2 (only one of which is shown in figure 1 ) extending in substantially vertical, reciprocally parallel retaining planes.
  • Each flank 2 comprises, in this case, two flat supporting plates 3 formed of metallic material and substantially step-shaped.
  • Each plate 3 is limited by a substantially vertical end face 4, which faces the face 4 of the other plate 3, and is provided with a plurality of reciprocally parallel teeth 5, which protrude in a substantially horizontal direction 6, are distributed along the face 4 and, in this case, are dovetail-shaped.
  • Each tooth 5 is separated from each adjacent tooth 5 by a corresponding recess 7, also dovetail-shaped.
  • the teeth 5 of each plate 3 slidingly engage the recesses 7 of the other plate 3 so as to allow the dovetail shape of the teeth 5 and of the recesses 7 to lock the plates 3 therebetween both in the direction 6 and in a substantially vertical direction 9 orthogonal to the directions 6 and 8.
  • the stairway 1 further comprises a plurality of substantially flat, horizontal steps 10, which extend between the side flanks 2 in the direction 8, and are distributed along the side flanks 2 themselves.
  • Each step 10 is fixed to each flank 2 by means of at least two fastening screws 11, each of which extends through a corresponding hole 12 obtained through the corresponding flank 2, and engages the step 10 itself to lock the corresponding flank 2 in the direction 8.
  • some holes 12 are made at the coupling between the plates 3 and each comprises a first corresponding substantially semi-cylindrical portion 13 obtained through a bottom wall 14 of a corresponding recess 7 and a second corresponding substantially semi-cylindrical portion 15 obtained through a head surface 16 of the corresponding tooth 5.
  • Each plate 3 is further provided with at least one fastening bracket 17, which protrudes upwards from the plate 3 in the direction 9 to allow the fastening to the plate 3 itself of a vertical upright 18 of a protective railing 19 of a known type.
  • the stairway 1 presents some advantages mainly deriving from the fact that the shape of the teeth 5 and of the recesses 7 allows to reciprocally lock the plates 3 both in the direction 6 and in the direction 9 without requiring the use of further fastening members. Consequently, the stairway 1 presents considerably reduced costs, implies a relatively simple assembly and furthermore allows to reduce costs and volumes for storage and shipment.
