Detailed description of the embodiment or embodiments
[0361 Illustrated in Figure 1 is a wire rope barrier assembly 10 which includes a post 12 having a bifurcated end 14 which has an outboard post portion 16 and an inboard post portion 18 and a gap 20 between them, as is best illustrated in Figure 8. The gap or space 20 provides a location for receiving a lower rope 32, an intermediate rope 34, and upper rope 36 therebetween.
[037] As can be seen in Figure 1 the lower rope 32 is at the bottom of the space 20 and above this lies a- spreader or spacer 22 as will be described in more detail below with respect to Figure 10. The intermediate rope 34 lies at the upper end of the spacer or spreader 22. Over the free ends of the outboard portion 16 and inboard portion 18 is a post end cap 24 which is illustrated in more detail below with respect to Figures 4 to 7.
[038] As illustrated in Figure 6, the post end cap 24 includes two cavities 37 in the underside thereof to receive each of the termini of portions 16 and 18 of post 12. As best seen for figure 7 the cap 24 has its own bifurcated end, formed by a slot or space 26, between the wails and portions of the cap 24 which surround cavities 37. The post cap 24 is positioned on. the post 12 and is dimensioned so that a lower slot 28 will be positioned above the intermediate rope 34.
[039] Between the intermediate rope 34 and lower rope 32 is located a retainer 35 which is best illustrated in Figure 9. It is preferably manufactured from stainless steel in a continuous band, or a band which has its free ends joined as illustrated in Figure 9. It is sized and shape so as to receive, by a sliding fit, the outer periphery of the post 12, to thereby help retain the wire rope's and the integrity of the upper end of the post 12 in the event of a collision and to control the point, or timing, of the release of the cables with respect to the post 12 in the event of a collision.
[0401 Illustrated in Figures 2 and 8 it can be seen that the cross section of the post 12 is similar to the numeral 3, and is called a SIGMA post or section.
[041] Illustrated in Figure 4 is a detail of the upper slot 26 in the post cap 24 which provides a space 26 between inboard and outboard portions of the cap 14. As best seen in Figure 6, the "sides" of the slot 26 are open, which, because the slot 26 is diverging in an upward direction, exposes several millimetres of the edge of the slot 121 in the post 12. This ensures that the slot 121 in the post 12, does not interfere, hinder or delay the upper wire rope from exiting the slot 26- Further by this means, it prevents the upper wire rope in slot 26 from lifting the cap 24 off the post 12, until the cap 24 is pushed off by the intermediate rope 34, as it leaves the slot 121 in the post 12. This ensures'that the bracing provided by the cap 24, in addition to the retainer 35 of figure 9, help to maintain the integrity of the top of the post 12, thereby permitting a greater absorption of energy by the intermediate and lower wire ropes 32 and 34.
[042] In other embodiments as illustrated in Figures 13 and 14, the illustrated cap works in a different manner. The slot 26 can be such that the upper end of the slot or space 26 has a width W1 which is of a lesser dimension than the width W2 at the lower end of the space or bifurcation, so that the sides of the slot 121 in the post 12 will not protrude through the cap 24 into the volume of the slot 26. This width W2 can wide enough to accommodate the outer or outside diameter of the wire rope 36 whilst the width W1 can of a lesser dimension which the upper wire rope 36 will have to push past by as it moves down into the base of the space or slot 26. This means that once the wire rope 36 is in position in the vicinity of the lower end of the space 26, force of sufficient upward magnitude must be applied to the wire rope 36 for it to escape from the upper reaches of the slot 26 and again push past the lesser width W1. Such a system will require the cap to be secured to the post 12, such as by a pop rivet or self tapping screw or other means, because otherwise the cap 24 with such a restriction may otherwise be lifted off the post 12 as soon as the upper wire rope 36 moves upwardly with respect to the post. This may mean that the extra bracing supplied by the cap 24 and the retainer of figure 9,will otherwise fail before the post 12,has time to absorb as much impact as possible.
[043] As is visible in Figures 5, 6 and 7 the lower end of the cap 24 has a space 28 which when the assembly is assembled will sit above the intermediate rope 34. This ensures that the wire rope 34, will not immediately begin to move the cap 24 off the end of the post 12, until the height of the slot 28 has been travelled through by the rope 34. This helps to maintain the integrity of the upper end of the post while the cap 24 remains in place.
[044] The cavities 37, as-illustrated in figure 6, are bounded on their outer peripheries by the internal surface of the outer walls of the cap 24. However, the internal surface of the cavities 37 are bounded by respective walls 39 which connect the lower region of slot 26 to the upper region of slot 28. These walls 39 also provide some structural integrity to the cap 24 by interlinking the opposed flat sides of the cap 24.
[045] The post cap 24 can be injection moulded or made by any appropriate manufacturing process but is preferably made from polymeric material with appropriate tV stabilisers. While the post cap 24 would be stronger if manufactured from cast steel or such like, it is best to keep the cap 24 as lightweight as possible, to ensure it has a least amount of momentum as possible is carried by the cap when it is moving, due to the eventual separation of the cap 24 from the post 12 in the event of a collision.
[046] Illustrated in Figure 10 is the spreader or spacer 22 which shows the construction of the spacer or spreader 22. The spreader 22 includes an upper bight 221 and a lower bight 222 which are of a diameter which is approximately equal to the outside diameter of the wire ropes 32 and 34. The left and right longitudinal sides include channels 223 and 224 which channels are of a width to readily receive the thickness of the post 12 in the vicinity of its slot 121 as is best illustrated in -Figure 3 and 8. The spacer or spreader 22 helps to maintain the lower cable 32 and intermediate cable 34 at an appropriate spacing of approximately 160 millimetres between the-centres of the wire ropes.
[047] Illustrated in Figure 9 is the stainless steel retainer 35 which has an internal length or sized so as to snugly and slidinglyfit around the outer periphery of the post 12 and is preferably located in the region between the wire ropes 32 and 34. When assembling the wire rope into the post 12 the retainer of Figure 9 is positioned after the rope 32, the lowermost rope, has been located inside the gap provided at the upper end of the post 12.
[048] Illustrated in Figure 11 is a wire rope barrier system similar to figure 1 with a cap 24 similar to that described above, except that a lower slot 28 is not provided and the retainer of a height to bridge the upper circumference of rope 32 and lower circumference of rope 34. The retainer 35 is thus used as both as a reinforcement and as spacer (obviating the need for the spreader 22) between lower wire rope 32 and intermediate wire rope 34.
[049] The barrier system of figure 12 is similar to that of figure 11, except that two upper wire ropes 36 are located in the slot 26 in the upper end of the cap 24.
[050] Where ever it is used, the word "comprising" is to b4 understood in its "open" sense, that is, in the sense of "including", and thus not limited to its "closed" sense, that is the sense of "consisting only of". A corresponding meaning is to be attributed to the corresponding words "comprise", "comprised" and "comprises" where they appear.
[051] It will be understood that the invention disclosed and defined herein extends to all alternative combinations of two or more of the individual features mentioned or evident from the text. All of these different combinations constitute various alternative aspects of the invention.
[052] While particular embodiments of this invention have been described, it will be evident to those skilled in the art that the present invention may be embodied in other specific forms without departing from the essential characteristics thereof. The present embodiments and examples are therefore to be considered in all respects as illustrative and not restrictive, and all modifications which would be obvious to those skilled in the art are therefore intended to be embraced therein.
