  • each barrier taking the form of a disc that forms a ring around a roadside fixture, each disc comprising a plurality of interconnected modular impact segments 2, fitted to a roadside light pole 3 via means of a collar 4, that permits the ring 1 to rotate about the pole 3.
  • Each modular impact segment 2 is a sector when viewed from above, having an inner circumference edge 5, and an outer circumference edge 6, bounded by two equi-distant radii edges 7a and 7b.
  • One radii edge has a female slot 8 incorporated therein, and the other edge 7b, has a complementing male portion 9 fixed thereto.
  • the outer circumference edge 5, has a slot 10 incorporated therein as well.
  • Each impact-absorbing barrier is assembled by interconnecting a plurality of modular segments 2 via the corresponding male and female portions 8 and 9, around the collar 3, and then wrapping a steel band 11 around the outer circumference of the newly created ring 1 , such that the steel band 11 is seated in the slot 10 in the outer circumference of the ring 1.

  • the lower disc 34 rests upon these RHS angles, and is free to rotate relative to both these and the pole 3.
  • Each of these mounting schemes can include supporting legs 41 , which allow the impact absorbing barrier ring to support weight if desired, so that the ring can double as a seat or bench, or even a pot planter or the like.
  • the modular impact segments 2 may have a shell made from a durable, deformable plastic material 45 such as polyethylene, alternatively they may be made from a metallic material or even fiberglass.

  • the shells can be left hollow, or an impact absorbing composite structure could be used; or a material such as sand, shredded tyre pieces, or shredded recycled plastic could be used, depending on the application.
  • Combinations of segments 2 containing fillings of varying impact absorbency can be used to create an impact absorbing barrier ring that will provide varying degrees of energy absorbency at differing points on the ring. This might be desirable for impact absorbing barrier rings that are to be used on objects that are proximate to high-speed roads such as highways or freeways, where vehicles will be approaching the object and ring from one direction, at high speed. It is considered that a variance in the impact properties of the impact ring segments would assist to deflect a vehicle around the object. For instance, the segments facing traffic are adapted to accept the brunt of the impact, and deflect the vehicle to the segments on either side, which may be filled with a material that is less elastic, so as to deflect the vehicle away from the object.
  • each segment 60 could be comprised of a plurality of annular compartments 65 each filled with impact absorbing fillings. These compartments could then be removed by cutting them from the segment. Removing compartments from the inner circumference would allow the ring to be adapted for fitment to a larger object. Removing compartments from the outer circumference would allow the ring to be adapted to situations where the ring would otherwise encroach on the thoroughfare.
  • a further advantage of constructing ring segments from a plurality of annular compartments is that different compartments can be filled with various impact absorbing materials.
  • the outermost compartments 70 could be filled with a material of high-energy absorbency, while successively inwardly segments 75 and 80, might be filled with materials of progressively lessened energy absorbency.
  • the modularity of such an impact absorbing barrier ring offers significant advantages. Firstly, it allows an impact absorbing barrier ring to be specifically adapted to a given application, and it allows this to be done easily, on site. Secondly, if a portion of the impact absorbing barrier ring is damaged, only the damaged segments need be replaced.
  • Compartmented segments could have annular slotted apertures 85 running between compartments and through the segment. Steel bands or cables could then be passed through these apertures further strengthening the impact ring. These slotted apertures could be used secure a segment of a greater radius 90 to the remainder of the segments 95 that comprise a ring 100. Once again, this would prove to be of advantage in instances where it would be desirable to provide an absorbing barrier ring with greater energy absorbency characteristics at one point on the ring.
  • a further application for the invention might use a plurality of impact absorbing barrier rings fitted to a plurality of spaced apart vertical uprights for the purpose of forming a roadside barrier or guardrail.

Abstract

L'invention concerne une barrière d'absorption de chocs (1) comprenant une pluralité de segments modulaires (2) reliés entre eux, maintenus ensemble par des moyens de liaison, la barrière étant conçue pour être montée sur un objet (3) de bord de route à l'aide de moyens de fixation rotatifs (4), de sorte que la barrière (1) entoure l'objet de bord de route et peut tourner autour de ce dernier. En cas de collision d'un véhicule avec la barrière, la barrière absorbe une partie de l'énergie du choc tout en déviant simultanément le véhicule autour de l'objet par rotation autour de l'objet.
