Definitions

  • the present invention relates to a method of assembling wooden parts for use of a straight staircase with a central stringer.
  • the ready-to-climb staircase which constitutes the invention has for main characteristic the rod of assembly of the two stringers which makes it possible to join together the whole and makes possible an easy and very fast assembly for an esthetic, sober, modern and economic result.
  • the assembly process consists in first bringing together 2 central stringers serving as a rack by means of a threaded rod by step, on which 2 nuts are screwed, each nut being accompanied by a washer. On the racks thus put in place, the blocks formed by gluing or assembling the step and its support are placed, blocks notched for this purpose. We then forcefully remove the nuts, and it is the tension thus obtained which secures the whole.
  • the steps and step supports which constitute standard elements, can be formed from a single block of wood, or by assembling and or gluing 2 elements, which represents a more economical solution.
  • the shape of the pieces can vary, for example to meet aesthetic purposes.
  • the shape of the notches can also vary.
  • Figure 1 shows, in exploded view, the assembly according to the invention.
  • FIG. 2 represents, seen from the front, an assembly module once produced according to the method.
  • FIG. 3 represents, seen from the front, a piece of the staircase thus obtained.
  • the assembly includes 2 central wooden stringers serving as a rack (1), joined by their internal face by means of a threaded rod (2) on which 2 nuts (3) and 2 washers are inserted. (4) inserted between the stringer and the nut, as many times as there are steps.
  • the step (5), and its wooden support (6), assembled or glued with wood glue or assembled and glued, are inserted in a notch (7) provided on the external face of each stringer, in the center of which is drilled a round hole (8) for the threaded rod.
  • Figure 2 shows the assembly of a module once the 2 nuts (3) and their washers (4) are screwed onto the threaded rod (2) engaged in the round hole (8) provided on each stringer, to maintain forces the spacing of the 2 central stringers (1) and the positioning of the step (5) and its support (6), of which a notch (7) ensures the embedding.
  • Figure 3 allows to visualize the succession of assembly modules described above along the central stringers for rack use (1), a threaded rod (2) accompanied by 2 nuts (3) and 2 washers (4) holding the spacing of the stringers and the installation of the steps (5) and step supports (6).
  • This assembly process makes industrial manufacturing possible by simplifying the elements, making it possible to produce a ready-to-assemble staircase, assembled with simple and limited tools, for an aesthetic and sober result.
