Definitions

  • the invention relates to an installation forming a portable platform, in particular for outdoor shows.
  • the invention therefore relates to an installation forming a portable platform, characterized in that it comprises a tilting base, having a given lift base, a rigid frame fixed to said base, at least two guide rails each articulated to said framework and at a distance from each other to be deployed parallel to each other beyond said lift base, each spar comprising a guide element so as to materialize two parallel rails in a deployed position of the installation and at least one floor of width corresponding to the spacing of said beams in said deployed position, comprising rolling means ment side cooperating with said rails.
  • the proposed installation includes lifting means by screw jacks to allow the base to be hoisted to the height of the platform of a truck or a trailer.
  • These screw jacks can be movable relative to the base, so that they can be positioned outside the base for supporting the base, during a loading (or unloading) phase of the installation folded over. the aforementioned trailer.
  • swivel seats are integrated into the thickness of the aforementioned floors, so that, as soon as the latter are in position between the side members, several rows of stepped seats can be deployed in a few seconds ; the straightening of a row automatically controlling the straightening of the next row.
  • Figure 1 there is shown in broken lines the general silhouette of the installation 11 in the folded position.
  • This installation comprises, in particular, a tilting base 12, having a given lift base relatively small compared to the span of the deployed installation, as well as a rigid frame 13 fixed to this base and with respect to which s articulate the various moving parts of the installation which have not been shown in detail in FIG. 1, for greater clarity.
  • Figure la shows the assembly mounted on the platform 14 of a trailer 15.
  • the installation is provided with autonomous lifting means, essentially consisting of four vertical screw jacks 16.
  • Each cylinder therefore comprises a telescopic rod 17, directed towards the ground, and the movement of which is controlled by a motor 18, for example a geared motor.
  • the jack is secured at its lower part to a horizontal arm 19, mounted pivotally (pivot axis 20) on the edge of the base.
  • the arms 19 occupy the positions shown in FIG. La, so that the jacks 16 are grouped towards the middle of the folded installation.
  • the arms 19 are made to pivot horizontally by about 180 °, so as to place the jacks 16 outside the support base of the base 12.
  • Locking means 21 improve fixing the arms 19 along the base 12 in this new position.
  • Figures Ib and lc illustrate this situation. Thus, unloading is carried out very simply once the jacks 16 occupy their new position.
  • Figure 2 illustrates about a quarter of the folded installation, since it consists of four similar sub-assemblies A, B, C and D.
  • Sub-assemblies A and B occupy half the length of the installation and have a generally symmetrical structure with respect to the central core 25 of the framework 13.
  • the same is true of the subsets C and D.
  • the subset A we see that it is mainly consisting of two groups Ga and Gb of three guide rails 27, 28 and 29, articulated to each other, in each group, by their ends.
  • the side members 27a and 27b are articulated by respective hinges 36, to the frame 13 and more particularly to the ends of lateral supports 30a and 30b, respectively, fixed and parallel, both perpendicular to the base 12 and to the middle core 25.
  • the side members 27-29 and the support 30 have at their upper part guide elements 31 with a C profile (see FIG. 4) connecting end to end and in alignment in the deployed position of the installation, so as to define two parallel rails 32a and 32b, as shown in FIGS. 3 and 4.
  • guide elements 31 are pierced with holes 35, arranged at regular intervals and whose role will be explained later.
  • the longitudinal members 27, 28 and 29 have an increased rigidity thanks to a structure of metallic lattice beams, underlying the corresponding guide element. They are generally trapezoidal, to allow the tilting of the assembly.
  • the smallest base (b l ) of the trapezium forming a spar (27b) is of the same dimension as the largest base (b 2 ) of the trapezium forming the neighboring spar (28b) and these two spars are articulated by hinges (38) along these two bases.
  • the lateral supports 30a and 30b also have a structure of metal lattice beams subtending the corresponding guide element and the larger base of the trapezoid forming the spar 27 is articulated by a hinge 36 at the outer edge of the support 30.
  • the hinge 37 between two beams 28 and 29 is arranged in the vicinity of the internal planes of these beams, to allow a 180 ° pivoting of the beam 29 relative to the beam 28.
  • the articulation hinge 38 between a beam 27 (c '' i.e. the spar closest to the base) and the neighboring spar 28 is offset inwardly to allow the folding of all of the beams 28 and 29 against the internal surface of the beam 27.
  • each sub-assembly has four floors 40 arranged vertically side by side in the vicinity of the central core 25 and parallel to it. Each floor has a length corresponding to the spacing of the longitudinal members of the groups Ga and Gb, in the deployed position of the installation, that is to say the spacing of the supports 30a and 30b. Each floor is provided with lateral rolling means cooperating with the rails 32a and 32b.
  • these lateral rolling means consist essentially of two rollers 42, located respectively along the lateral edges of said floor and engaged in the neighboring rail 32, said rollers being on the same axis and each located substantially in the middle of the corresponding lateral edge. from the floor.
  • the floor 40 can pivot at least 90 ° relative to the rails 32, while remaining substantially in a state of indifferent equilibrium.
  • one or more cables 48 ensuring the control of the deployment, is fixed in the vicinity of the free edge of the floor. further away from the base 12, that it passes around a pulley 49 mounted in the vicinity of the free edge of the floor closest to the base, and that it winds around a control shaft 50 mounted on the said base.
  • This shaft can, for example, be rotated by a gear motor or the like.
  • the free edge of the floor closest to the base 12 is provided with two opposite lateral rollers 51, subject to movement along two respective vertical guides 52, integral with the base 12.
  • each floor 40 has rows of retractable seats in its thickness.
  • the legs 54 of the seats are pivotally mounted around a rigid tube 56 of the floor.
  • the tubes 56 corresponding to the different rows of seats therefore extend parallel, at regular intervals, over the entire length of a floor, that is to say over a distance slightly less than the spacing of the rails 32a and 32b.
  • each tube has in each of its end portions locking rods 58 capable of sliding axially and projecting laterally beyond the floor, to engage in one of the holes 35 formed in the elements of guide 31.
  • the locking means 60 are constituted by a number of hooks with an inverted U profile arranged along the free edge of the step plane 59 while said cooperating means 61 are constituted by as many movable stops along the length of the floor (that is to say perpendicular to the plane of FIG. 8) and biased in a position given by a spring.
  • the lower part of each stop has a cam profile designed to cause its erasure when it meets the hook when the step plane is raised.
