Definitions

  • the present invention relates essentially to the field of prefabricated houses and particularly a staircase of metal carpentry consisting of fitted modular units designed to be easily assembled by bolting. This facilitates at most the transport and the assembling on the spot.
  • Stairs to enter prefabricated houses are presently known and have to be made to measure by arranging the requested height, inclination and number of steps beforehand in workshop.
  • One object of the present invention is to provide stairs for the above-mentioned use, characterized in that they consist of fitted modular units to be assembled on the spot, without the need of arranging "ad hoc" parts for any application.
  • a second object of the invention is to provide stairs of different size and types by adding and taking away easily single fitted units.
  • a third object is to allow the rise to be adjusted so that the staircase can be arranged for any difference of height. This is accomplished by providing suitable slotted holes to adjust the height of each step.
  • the modular staircase of the present invention consists essentially of a pair of side base members B, a pair of footpace supporting members PP for each footpace, to which a pillar or upright C provided with upper support arms for such pair of footpace supporting members PP, and a plurality of steps, each of them has in combination: a pair of step supporting end members PG, a step G, one or more side banisters P.
  • base members B are bolted to the lower arms of the step supporting members PG of the lower step of the staircase, after having bolted the corresponding step G thereto.
  • each step supporting member PG is essentially Z-shaped, the central horizontal portion of which supports step G, and the lower and upper arms perpendicular to the central connecting portion are directed downwards and upwards, respectively. At least one of such vertical arms is provided with such pair of elongated holes or vertical slots F adjusting the rise, in which the securing bolts are fitted.
  • each footpace supporting member PP is different from the corresponding step supporting members PG only by the greater length of its horizontal central portion.
  • each pair of modular units (figures 3 and 4) forming the steps and the footpaces of the staircase according to the invention consist of two (right and left, respectively) members specular to each other.
  • banisters P consist of tubular "U"-bent members welded to a lower plate provided with mounting holes
  • the base members B, the step supporting members PG, and the footpace supporting members PP are preferably provided with profiles having a "C"-shaped section to ensure the rigidity.
