Definitions

  • the present invention is in the field of mobile constructions and its subject is a device of the platform type, or platform, with steps, intended either to allow the arrangement of people so that these people are well seen by another person, a photographer for example, or to allow people present on the platform to have a wide field of observation, for example on a sports or entertainment event.
  • the present invention aims to provide a platform or platform whose implementation is very rapid, following a move from one place to another for example, which has all the safety conditions required for people arranged or installed on it, and whose ratio of the number of spectator seats to the congestion in the folded state is significantly greater than that of the devices of the prior art.
  • a tiered tribune in particular intended for the disposition of persons, either for the purpose of photographing them, or for the purpose of enabling them to attend a spectacle, a conference or other events, of the type comprising a frame mounted on wheels provided with coupling means, a first group of so-called high steps fixedly mounted on the chassis, and a second group of so-called low steps articulated on the first group about a horizontal axis parallel to the steps of the high groups and low, the low group which can be, by tilting around the axis, folded and embedded in the high group in a so-called road position, or alternatively be deployed to adopt a position of use, is characterized in its generality in that that each of said top and bottom groups of steps comprises a group of steps, called external, which has a hollow prismatic structure, and in that each of these said top and bottom groups serves as a housing for at least u n group of steps of analogous shape, said interior, which can be extracted by sliding.
  • each group of external steps comprises in its middle part stiffening members, or stiffeners, in a plane perpendicular to the lines of the steps; in addition each group of interior steps has stiffening members at its ends; further abutment means are arranged at the ends of the groups of external and internal steps so as to prevent the complete extraction of the internal steps.
  • the end stiffeners of the interior steps serve in the position of use of end stiffeners to the exterior steps.
  • each step being formed of a vertical part and a horizontal part
  • the horizontal part consists of two horizontal bearings connected by a substantially vertical wall; it results from this conformation, known in itself in its application to steps but particularly advantageous and adapted to the case where one seeks precisely the transverse stiffening of the tubular structures, that the vertical wall serves both to delimit the zone where can s '' sit the spectators arranged on a bleacher and the area where the feet of the spectators arranged on the upper bleacher can rest, and contribute to stiffening the structure of the bleachers.
  • vertical slides are arranged in the vicinity of the end angles of at least the high interior groups, said slides being intended to allow the fixing in a removable manner, on the one hand , crutches, on the other hand handrail posts; preferably these slides exceed the cross section of the inner steps so as to form abutments for driving the inner steps into the outer steps, and means for grip for the extraction of interior steps.
  • the extraction stop means consist of rods, one end of which is fixed to the stiffeners arranged in the middle part of the external steps, the other end of which comprises a "head", said rods being slidably arranged in holes in the stiffening members with which the groups of interior steps are provided; it follows from these provisions that these stop function members are not visible on the outer faces of the steps when they are deployed.
  • the height of a step is approximately forty centimeters, its total width of sixty centimeters, each landing a width of twenty-five centimeters and the wall connecting them, therefore being an oblique wall, having a height of ten centimeters.
  • the distance between the hinge axis and the lowest part, after deployment, of the group of low external steps is equal to the distance separating said axis from the bottom part of the wheels of the chassis.
  • a trailer intended to constitute a grandstand in accordance with the invention consists mainly of a chassis 1 mounted on wheels 2 and can be coupled to a vehicle by means of a drawbar 3.
  • a first group 4 of steps fixed relative to the chassis Above the chassis are arranged a first group 4 of steps fixed relative to the chassis and a second group 5 articulated on the first group around a horizontal axis 6.
  • the bleachers of the first group 4 are said to be high since they are going to be located in the upper part of the gallery; the bleachers of the second group are said to be low since after tilting around axis 6 they will constitute the lower part of the grandstand.
  • each of the aforementioned groups 4 and 5 has a hollow or tubular prismatic structure intended to telescopically contain so-called interior groups such as 7 and 8 respectively of steps similar to the outside steps.
  • the groups of interior steps such as 7 and 8 have a length approximately equal to half the length of the external steps, so that each group of external steps contains two groups of internal steps.
  • This division into two of the inner steps has the advantage of allowing the presence of stiffening members 9 and 10 in the middle part of the outer steps; thus groups of internal steps 11 and 12 similar to groups 7 and 8 are arranged in the external steps symmetrically to the latter with respect to the stiffening members.
  • groups 7 and 8 can slide according to arrows 13 and 14 respectively at the front end of the trailer and groups 11 and 12 can slide in the same way according to arrows 15 and 16 respectively the rear end of the trailer.
  • the towable platform in fig. 1 is shown in a deployed position in which only the groups of inner steps of the front end, that is to say the groups 7 and 8 were extracted by sliding out of the groups of outer steps 4 and 5; we notice at the inner end of groups 7 and 8 stiffening members or structures consisting for example of tubular assemblies 20 for the upper steps and 21 for the lower steps; the structures 20 and 21 have been shown different, not because of any technical necessity but to give an illustration of various possibilities of realization of this and it should be understood that these structures could be similar, whether they are of either form; such structures, or members, of stiffening are found at the two ends of each of the groups of interior steps whether they are upper or lower or front or rear end; the stiffening member with which the second end of the group of steps 8 is thus partially represented at 22.
  • stiffening organs or structures are again found in 9 and 10 in the median plane 19 of the groups of outer steps respectively upper and lower and what was said previously for the stiffening organs of the inner steps is still true for these stiffening organs outside bleachers.
  • stiffening members 9 and 10 occupying part of the interior space of the tiers, constitute an interior abutment or the insertion of the groups of interior tiers.
  • stiffeners such as 22 serve not only as stiffeners for the inner steps in which they are incorporated, but also as stiffeners for the outer steps in which remains housed, even after extraction, the end of the inner steps.
  • the stiffening structures such as 22 also participate in an extraction stop function thanks to rods such as 23 fixed at 25 to the stiffeners of the middle part such as 10, mounted sliding in holes in the stiffeners such as 22 and comprising a head such as 26 and 27 against which the stiffening members such as 22 abut.
  • a schematic section of the gallery of the invention by a transverse and median vertical plane shows that the preferred form of the preceding figures comprises for groups 4, 7, 11 high steps four steps, that is to say the possibility to have four rows of people seated, and for groups 5, 8, 12 of the lower steps three steps, which after pivoting around the axis 6 can be embedded in the upper steps. It will be noted that if the distance 41 between the hinge axis 6 and the lowest part after deployment of the group of lower outer steps, is equal to the distance separating this axis from the lower part of the wheels, the group of steps low, in the deployed position, will rest on the ground.
  • each step is formed by a vertical part 42, a horizontal part 43, the horizontal part itself consisting of two horizontal bearings 44 and 45 connected by a wall 46 inclined or even substantially vertical; part 44 can be used as seats while part 45 can be used as a footrest for spectators seated on the upper tier; another function of this conformation of the horizontal part is to provide, thanks to the existence of the wall 46, a stiffening of the structure which is particularly sought after because of the tubular nature of the latter.
  • the height 50 of a step is approximately forty centimeters, its total width 51 approximately sixty centimeters, each landing 44 and 45 having a width 52 of twenty-five centimeters and 53 respectively of twenty five centimeters;
  • the height 54 of the oblique wall 46 has a height of ten centimeters for a horizontal offset 55 of about five centimeters.
  • Fig. 6 illustrates a first characteristic of this second embodiment according to which each group of upper 60 and lower 61 steps houses a single group of internal steps, 62 and 63 respectively.
  • FIG. 5 is schematically illustrated and exploded operating means for moving from the road position to the position of use and vice versa; these operating means essentially consist of two groups of hydraulic cylinders, each group of cylinders being arranged at one end of the platform, namely a group at the front end and a group at the rear end.
  • Each group of jacks comprises a first jack such as 65 articulated at a point 85 at one end of a cross member such as 66 of the group of high outside steps 60 and a second jack 67 articulated at a point 86 at the group of low outside steps, the first and second cylinders being moreover articulated to one another, and more exactly one at the end of the other, at a point of articulation 70.
  • these two end jacks have been shown, separated from the grandstand, on the one hand in an “out” position (closest position to the stand) and in an “in” position (most far and the lowest in the drawing).
  • the two jacks are arranged along the crosspiece 66, the groups of low steps then occupy the position illustrated partially in dotted lines in the figure, position corresponding to the deployed position, or of use, of the tribune.
  • the grandstand we first start by taking out the jacks 65, called first, until they are at the end of their travel; the so-called second jacks such as 67 then serve as a connecting rod for pivoting the groups of low steps around the axis 87; when the first jacks are at the end of their travel, the end of their piston rod then being substantially perpendicular to the axis 87, the second jacks such as 67, which are multi-stage jacks, are taken out, up to that the lower tier groups occupy the position as shown in the figure, the position corresponding to the folded, or road, position of the grandstand; this position also corresponds substantially to the end of travel position of the second cylinders.
  • the stands are provided with seats, these seats being able to be fixed seats 81 for the stands of the groups of outside stands 60 and 61, and may be movable seats, tiltable or removable, for the tiers of groups of interior tiers 62 and 63.
  • the tiltable seats are associated by plurality of three on a chassis such as 80 (fig. 7) articulated itself on a spar of a group of interior steps; four pluralities of three seats can thus form a row of seats in a group of high or low interior steps.
  • Certain other seats in the interior tier groups such as those intended for either the upper row of the upper interior tier group or the lower row of the lower interior tier group are also associated by a plurality of three on a chassis, but this chassis this is removable; during transport, this removable chassis and their seats will be housed in the interior of the group of tall interior bleachers; the disassembly of the seats is necessary due to the fact that as it appears on the drawing they do not have the space necessary for their tilting.
