    • E01F13/022—Pedestrian barriers; Barriers for channelling or controlling crowds

Definitions

  • the present invention relates to a security barrier intended to contain or channel a crowd.
  • Safety barriers currently known such as those described in patent documents FR-A-1 363 138 or FR-A-1 473 733 have a common structure comprising a frame formed by two horizontal rails, an upper and a lower, and two vertical uprights between which are arranged vertical bars.
  • the frame of these safety barriers is supported by two feet of variable shape, said feet protruding from the vertical frame of the barrier. In most of the existing models, the feet are indeed positioned perpendicular to the plane containing the frame of the barrier.
  • the object of the invention is to remedy the drawbacks of the previous barriers.
  • a protective barrier according to the invention comprises a vertical frame constituted by an upper beam, a lower beam, and two uprights.
  • Said lower rail is connected on the one hand, by its ends to the uprights of said frame, and on the other hand, to the upper rail of said frame by means of bars.
  • Said lower beam is bent at its ends in order to form a central spar parallel to the upper beam and two lateral crosspieces.
  • the free ends of the uprights of the safety barrier form the feet of said barrier.
  • the bottom rail is provided with at least one foot.
  • the feet are vertical or re-entrant.
  • angles formed by the elbows of the bottom rail are obtuse angles.
  • angles of the elbows of the bottom rail are substantially equal to 135 degrees.
  • the safety barrier shown in FIG. 1 comprises a vertical frame 1 constituted by an upper heald 2, and two vertical uprights 3.
  • a bent lower heald 4 is connected, on the one hand, by its ends to the uprights 3 of said frame 1, and on the other hand, to the upper heald 2 of said frame 1 by means of bars 5.
  • the bent lower heald 4 forms a central spar 6 parallel to the upper heald 2 and two lateral crosspieces 7.
  • the central beam 6 of said rail 4 is offset relative to the vertical plane containing the top rail 2 and the two vertical uprights 3.
  • the barrier then has, seen from above, a base forming a quadrilateral and, seen from the side, a triangular shape. Therefore, it is possible to maintain the barrier in a standing position by adding vertical feet 8a and 8b which will not protrude from the support polygon, thus avoiding any incident with the feet of the barrier.
  • two 8a will advantageously be constituted by the ends of the uprights 3 of the frame 1 in order to reduce the costs and the manufacturing time.
  • At these two vertical feet 8a at least one vertical foot mounted on the bottom rail 4 can be added (two feet 8b are shown in Fig. 1).
  • the embodiment with four vertical feet 8a and 8b described in FIG. 1 is particularly advantageous. In fact, it will be understood that the shape of the feet does not matter as long as they do not exceed the support polygon of the barrier. To do this, said feet 8a and 8b must be vertical or re-entrant.
  • the width of the basic quadrilateral will be defined to be as small as possible while ensuring good stability of the barrier.
  • the angle between the central beam 6 and the lateral crosspieces 7 is an obtuse angle.
  • Such a choice allows, when several barriers are connected linearly to each other as shown in the left part of FIG. 2, to leave a free space 9 between the adjacent barriers thus allowing the speakers to be inserted on the show side or a representative of the order for example.
  • the angle chosen is approximately 135 °. It also makes it possible to form right angles between two adjacent barriers as shown in the right part of FIG. 2.
  • the connecting means between the barriers are not the subject of the present invention and will therefore not be described here. Such means are known to those skilled in the art and are for example described in the French patent document FR-A-1 363 138.
  • the central beam 6 being offset relative to the vertical plane containing the top rail 2, the center of gravity of the barrier is shifted forward, on the show side. This results in better stability and a much lower probability of the barrier overturning under crowd pressure.
  • This same offset of the central beam 6 allows the removal of the lower horizontal rail which formed the framework of many anterior barriers. This deletion has the advantage of reducing the possibilities of escalation of the safety barriers by the crowd since it is by resting on the bottom rail that the spectators managed to cross said barriers.
  • uprights 3 of frame 1 are not necessarily vertical.
  • the safety barriers according to the invention can be stacked against each other without longitudinal offset from each other.
  • each barrier is fitted into the preceding barrier so that the frames 1 and the bottom rails 4 of each of the stacked barriers are placed side by side. Stacks of rectangular shape are thus obtained having a minimum bulk which does not exceed the width of a barrier.
