Definitions

  • the present invention relates to a straight staircase, in particular a miller's ladder, a "kit” for mounting this staircase and a method of mounting the stairs.
  • the straight staircases in particular the miller's ladders are well known. They are arranged so that one end rests on a practically horizontal ground and that the other end is supported on a vertical surface. They have a specific footprint and allow to mount a specific height, the angle ⁇ between the axis longitudinal of the stringer and the ground being the angle of climb.
  • Straight stairs are generally made up of at minus a stringer or lateral upright in the form of a plank elongated rectilinear, preferably by two parallel stringers, and by steps fixed to at least one stringer by one of their ends, of preferably attached to a stringer at each of their ends.
  • the staircase right may have a bottom that closes the space between the steps.
  • the steps are simply made up of planks generally rectangular of sufficient width, which are fixed to the stringer so as to be horizontal when the staircase is in place.
  • a silt, or both stringers, may (or may) carry a handrail or ramp to balusters. These stairs are usually made of wood.
  • the present invention therefore relates to a straight staircase, in particular of the miller's ladder type, intended to be disposed between a practically horizontal floor and a practically vertical wall with a angle of climb ⁇ , said staircase comprising at least one stringer supporting at least one step, the average plane of the (or each) step can be oriented so that it does, with the axis longitudinal stringer, an angle substantially equal to the angle of climb ⁇ of the staircase, this orientation being achieved by rotation of the (or each) walks around an axis substantially perpendicular to the stringer using a whirling device constituted, in the vicinity of (or of each) stringer, by a blind bore in the (or each) stringer and a projection secured to the (or each) step, a means of support allowing to block with respect to the stringer (s) the (or each) walks in the position obtained by the orientation mentioned above, characterized in that the projection of the swiveling and the means for holding in position the (or each) steps are part of the same piece independent of (or each
  • the independent part is advantageously constituted by a square comprising two wings arranged at right angles on either side of an edge, one of the wings being a blade attached to a stringer and the other wing being a blade attached to the end of a step, the blade of the square fixed on the stringer bearing the projection associated with said step.
  • the square can be of any sufficiently strong material, such as a molded plastic or, preferably, a metal: steel, aluminum, copper. It is, more particularly, made of steel.
  • the projection carried by the square can be a cylindrical pivot obtained by molding when the square is made of plastic, or fixed on the blade when the square is metal.
  • the projection is preferably a boss or a flat obtained by stamping or other means of manufacture.
  • Each bracket is fixed by screws on a stringer and on a end of the steps, each of the blades of the bracket having screw holes.
  • the square is preferably arranged on the stringer so that the opening of the right angle is turned upwards, but this opening can also be turned down.
  • Each step is, in plan view, generally substantially rectangular and has large edges substantially perpendicular to the stringer (s) and small edges substantially parallel to the stringer (s).
  • the steps could include a rounding on the front edge of the stairs.
  • Brackets can be attached to the end of a step on its upper side, but for aesthetic reasons they are preferably fixed on its underside.
  • a rebate is preferably formed on its underside on a small edge of walking parallel to it for fixing one of the wings of the square.
  • the step preferably has a rebate at each of its ends.
  • the rebate advantageously has a depth close to the thickness of the wing of the square.
  • the staircase according to the invention preferably comprises two stringers which are, of course, parallel. On the inside of each stringer is provided with a series of blind holes regularly spaced along the longitudinal axis of the stringer, the distance between two bores corresponding to the desired distance between two steps. Each step is connected to the stringer by means of brackets, in a position such that its mean plane makes with the longitudinal axis of let us file an angle equal to the angle of climb ⁇ of the staircase. The steps are therefore parallel to each other and when the staircase is in place, they are horizontal.
  • the lower edge of the stringer that will rest on the ground can also be cut according to the angle of climb of the staircase right to adjust it to the ground surface, that is to say so that it does with the longitudinal axis of the stringer an angle ⁇ .
  • the lower edge of the stringer is rounded, for example in an arc. The lower edge can thus adapt to any angle of climb.
  • just cut the upper edge of the stringer so that it fits on the vertical wall. In some cases, this avoids modify the length of the staircase, i.e. cut it, adjusting only the top edge of the stringer.
  • This embodiment has the advantage of keeping the distance from the steps to ends of the stringers, which is not always the case when intersects the stairs.
  • At least one of the stringers can carry a handrail or banister railing.
  • the lower edge of the stringers is rounded, the upper edge preferably being perpendicular to the axis longitudinal of the stringer, so that it can be cut at the time of mounting.
  • the angle ⁇ is preferably measured using of a template.
  • Figure 1 shows a sucker scale 1 according to the invention. It is placed between practically horizontal ground and a practically vertical wall.
  • the climb height is designated by h and the footprint by e.
  • the angle between the longitudinal axis AA 'of the stringer (or of the longitudinal edges of the stringer) and the ground or angle rise of the sucker ladder is designated by ⁇ .
  • the staircase has a number of steps 6 which are consisting of boards of generally rectangular shape having large edges substantially perpendicular to the stringer and small edges substantially parallel to the stringer. Number of steps is generally equal to the number of bores in each silt. The space between two consecutive bores therefore determines the space between two consecutive steps.
  • a rebate 12 is formed in the thickness of step 6 parallel to the small edge of the step at each end of the step.
  • the steps 6 are fixed on the stringers 2 by brackets 7, or angles.
  • These 7 brackets are constituted by two wings 8, 9 arranged at right angles on both sides an edge, one of the wings being a blade 8, the free edge of which is parallel to the edge which is fixed on one of the stringers 2 and the other wing being a blade 9 whose free edge is also parallel to the edge and which, according to the embodiment shown, is fixed under step 6 to one end of it at the rebate 12.
  • the right angle of the square is facing up of the stairs.
  • Blades 8 and 9 are almost identical in length the width of the steps, the different brackets having the same width.
  • the brackets are in steel.
  • the blade 8 has in its center a boss 10, which has been obtained by stamping, and two screw holes 11 arranged symmetrically with respect to the boss.
  • the boss 10 has a shape and a dimension such that it can penetrate a blind bore 5 formed in the stringer 2, temporarily maintain the square 7 on the stringer 2 and rotate freely in the blind bore 5 of the stringer.
  • the blade 9 is also provided with two screw holes 11 for the passage of screws for screwing the step 6 onto the blade 9 of the bracket 7 at the level of the rebate 12.
  • a “kit” or set for making the ladder miller described above includes, in the unassembled state, two stringers 2 drilled holes in which are blind holes 5, the number steps 6 corresponding to at least the number of blind bores 5 on each stringer 2, a number of brackets 7 at least double the number of steps 6, and the number of screws at least equal to that necessary for mounting all steps 6.
  • a series of templates of this type is shown in Figure 5.
  • each square 7 it introduces the boss 10 in a blind bore 5 of the stringer and it rotates the square 7 so that its edge makes a angle ⁇ with the longitudinal axis AA 'of the stringer: it therefore applies the template hypotenuse C on the edge of the stringer and it has the edge of square it along side A of the right triangle. He then screws the square 7 on the stringer using screws passing through the screw holes 11 of the blade 8 of the square, preferably so that the free edge of the blade 8 opposite the edge of the bracket 7 is turned upwards from the stringer, that is to say opposite the rounded lower edge 3 of the stringer; the angle right of the square therefore opens upwards.
