Definitions

  • the present invention relates to one of these mechanical connecting elements, known by the name of "spacer", which allows to fix the rails of a guardrail on the posts located in the shoulder of a traffic lane . It also relates to the use of this spacer.
  • Safety guardrails along certain traffic routes such as expressways or lanes with risky sidesides, be it proximity to an obstacle or a significant difference in elevation, are well known to motorists.
  • These slides usually comprise stringers assembled end to end, usually with a slight overlap of their ends, and fixed at regular distances on posts located in the shoulder.
  • the most common stringers consist of a segment of a predetermined length of a profile having a section W. Depending on whether this section W is a succession of curves or, instead, forms a broken line, the guardrail presenting one of these two profiles is said to be of the "GSA" or, respectively, of the "GSB" type.
  • the slide thus formed is also fixed by means of bolts on posts, so that the sill located below, and therefore in contact with a pole, is placed downstream, in the direction of flow, with respect to this pole.
  • the desired effect of the slide is to prevent its crossing by a vehicle, while limiting the damage caused by the contact of the sills with the vehicle body.
  • the slides have a certain elasticity. But too much elasticity has the disadvantage of bouncing the vehicle on the slide. In certain situations, the vehicle runs the very serious risk of being thrown onto the taxiway in the opposite direction.
  • the spacer described in the patent application European EP-0.356.686 has an upper part having a high resistance to impact and a lower part, carrying the sill, pivotable about an axis parallel to the sill.
  • the rotation is controlled by breaking a zone whose mechanical strength is weakened by a series of holes.
  • This spacer is of the general shape of a rectangular parallelepiped having a vertical rear face intended to be fixed on a post implanted in the shoulder of a traffic lane, a vertical front face intended to be fixed to the sill, a part upper part provided with a reinforcing element, and a lower part of mechanical strength in a front-rear direction lower than the mechanical strength of said upper part.
  • It comprises two symmetrical hulls nested one inside the other, so that the wings of the hulls form the lateral faces of the spacer and are, therefore, perpendicular to the sill.
  • the present invention therefore aims to simplify to the extreme the structure and manufacture of a safety slide sill retractor of the type of those of the general shape of a rectangular parallelepiped having a vertical rear face intended to be fixed on a pole implanted in the shoulder of a traffic lane, a vertical front face to be attached to the sill, an upper portion provided with a reinforcing member, and a lower portion of mechanical strength in a lower front-rear direction the mechanical strength of the upper part.
  • a spacer of this type consists of two symmetrical hulls, having a U-shaped cross-section and each comprising two wings adjacent to a central core, nested one in one. other such that these wings form the front and rear faces of the spacer.
  • This spacer is also remarkable in that the central core of each of the shells has a top edge, which, on each shell, is very advantageously rotated in the opposite direction to that of the wings.
  • Each of these wings advantageously has at least one bore for receiving at least one bolt for attaching the sill to the post.
  • this bore is unique, and arranged substantially in the center of each of the wings.
  • Figures 1a and 1b are respectively a general perspective view of the two symmetrical shells constituting the safety slide sill retractor according to the invention, and a general perspective view of the assembled spacer.
  • Figure 2 is a schematic view after an impact of the spacer according to the invention mounted between a sill and a pole.
  • the preferred embodiment of the invention relates to a spacer 1 for use with the most common metal stringers 2.
  • Figure 1a shows separately the two symmetrical shells 3,4 whose spacer 1 is constituted.
  • These two shells 3, 4 have an identical U-shaped cross section. They each comprise two wings 5, 6, 7, 8 adjacent to a central core, respectively 9, 10.
  • the front wings 5.7 are intended to be fixed at the ends of the longitudinal members 2, while the rear wings 6.8 are intended to be fixed on a post 11 implanted in a shoulder 22.
  • This same bolt also makes it possible to assemble the two symmetrical shells 3,4 fitted one inside the other, that is to say in the position where the front and rear wings 5, 6 of a shell 3 are superposed. respectively to the front and rear fenders 7.8 of the other hull 4, as shown in Figure 1b.
  • each central core 9, 10 is reinforced by a rim 16, 17 advantageously rotated in the direction opposite to that of the wings, respectively 5.6 and 7.8.
  • the oblong holes 12, 13, 14, 15 of the wings 5, 6 and 7, are of dimensions substantially equal to 22 mm ⁇ 25 mm.
  • Each shell 3,4 is cut out of sheet steel and formed by a tool to be followed, the two wings 5, 6, 7,8 being bent at right angles on the same side of the central core 9,10 and the rim 12,13 being bent at right angles on the other side.
  • the sheet used is a sheet of 3 mm thick steel type E24, E36 or a similar type.
  • Such a spacer has the additional advantage of being constituted by two identical hulls, arranged symmetrically at the moment of their casing.
  • the separate shells 3,4, supplied at the place of mounting of the slide, are simply nested in pairs and made integral by the attachment bolt of the sill 2 on the post 11.
  • the flanges 16, 17 located at the upper part 18 of the spacer 1 provide said upper portion with mechanical strength in the front rearward rearward direction AR greater than that of the lower part 19, which results in by a flattening of the lower part 19 of the spacer 1 in the event of an impact on the slide 2.
  • the reinforcing element in the upper part 18 of the spacer 1 is presently executed in the form of a fold 16,17 at right angles to a rectangular extension of the central core 9,10 of each of the shells 3,4 .
  • Flanges 16, 17 having different profiles, in particular U or S, would contribute in an equivalent way to the reinforcement of the upper part 18 of the spacer 1.
