  • a glare screen system 10 comprises one or more glare screen units 12 arranged in a substantially end-to-end configuration.
  • Each of the glare screen unit 12 comprises one or more substantially upright and hollow paddles 14 extending from a substantially horizontal rail 16.
  • the paddles 14 are integrally formed with the rail 16, although it is also possible that the paddles 14 are connected to the rail 16 using other means, such as using mechanical fasteners.
  • three of the units 12 are shown connected end-to-end, but it is understood that many more of the units 12 may be connected together in a similar manner.
  • the glare screen system 10 may be installed on top of a concrete barrier 2 (such as those used as part of a highway divider for a highway 8), as shown in Fig. 1.
  • the paddles 14 further comprise two opposing paddle ends 63 that extend for substantially the entire height of the paddles 14, with the first and second faces 26, 28 joining at the paddle ends 63. Therefore, the first and second faces 26, 28 and the upper paddle surface 66 generally define, at least in part, a paddle enclosure 65.
  • the paddles 14 are preferably substantially hollow.
  • the paddles 14 are also preferably tapered, such that a horizontal distance between the two paddles edges 63 is closer together proximate the upper paddle surface 66 than proximate the upper surface 18.
  • the degree of tapering of the paddles 14 preferably varies depending on the particular location along the first and second faces 26, 28.
  • the degree of tapering of the first and second faces 26, 28 along proximate their vertical midlines M is preferably approximately 2.5°
  • the degree of tapering of the first and second faces 26, 28 proximate the paddle ends 63 is preferably approximately 2.7°. Therefore, the paddles 14 are preferably slightly more tapered along the paddle ends 63 than along the vertical midlines M of the first and second faces 26, 28.
  • the thickness of the paddles 14 preferably varies depending on the particular location along the first and second faces 26, 28.
  • the thickness of the first and second faces 26, 28 along proximate the vertical midlines M is preferably approximately 2.0 mm, while the thickness of the first and second faces 26, 28 proximate the paddle ends 63 is preferably approximately 2.5 mm. Therefore, the paddles 14 are preferably thicker along the paddle ends 63 than along the vertical midlines M of the first and second faces 26, 28.
  • the receiver upper surface 38 comprises two receiver lateral edges 39 and a receiver longitudinal edge 41, with the receiver sidewalls 40 extending proximate from the receiver lateral edges 39.
  • the receiver portion 34 may also comprise a receiver end wall 43 extending generally downwardly from the receiver upper surface 38 proximate from the receiver longitudinal edge 41.
  • the receiver upper surface 38 is preferably narrower than the upper surface 18, and the receiver sidewalls 40 are preferably shorter than the sidewalls 20, such that the receiver upper surface 38 is offset from the upper surface 18, and the receiver sidewalls 40 are offset from the sidewalls 20, as shown in Fig. 7.
  • the receiver portion 34 of one of units 12 is engaged with the attachment portion 36 of another of the units 12, the resulting engagement results in a relatively smooth and continuous transition between the upper surfaces 18 of the units 12 and a relatively smooth and continuous transition between the sidewalls 20 of the units 12, as shown in Fig. 8.
  • the depression 42 comprise a single depression with a substantially “figure-eight” (or lemniscate) shape comprising first and second lobes 44, 46.
  • the first and second lobes 44, 46 are substantially circular in shape, although there may be some overlap between the first and second lobes 44, 46. In other embodiments, other shapes or other numbers of depressions 42 may also be possible.
  • the depression 42 comprises one or more depression walls 82 that extends from and is continuous with the receiver upper surface 38.
  • the depression walls 82 are substantially vertical and defines, at least in part, the first and second lobes 44, 46.
  • the depression 42 further comprises one or more depression floors 84 extending across the depression walls 82.
  • the depression floors 84 are substantially horizontal and defines, at least in part, the lower surface of the depression 42.
  • the depression floors 84 may comprise one or more receiver openings 48 for receiving fasteners 50 therethrough for attaching the unit 12 to the concrete barrier 2, as shown in Fig. 1.
  • the fasteners 50 may include anchors, bolts, screws, or other suitable mechanical fasteners.
  • one of the receiver openings 48 is located in the depression floors 84 within each of the first and second lobes 44, 46.

  • a cap 100 may be provided to fit within and engage the protrusion opening 96.
  • the cap 100 is generally round and comprises a generally planar cap surface 102 with a circular cap opening 104 formed thereon.
  • the cap surface 102 comprises an outer cap rim 106 that extends generally downwardly.
  • a cap wall 108 extends downwardly from the cap surface 102, proximate to the cap opening 104.
  • the cap wall 108 is a substantially circular wall.
  • a cap floor 110 extends within the cap wall 108 (e.g., when the cap wall 108 is substantially circular).
  • the rail 16 may comprise one or more ribs 62 extending generally downwardly from the upper surface 18.
  • the ribs 62 extend from the upper surface 18 proximate to where the paddles 14 extend from the upper surface 18.
  • the ribs 62 may extend between the sidewalls 20 and generally follow the curvature of the first and second faces 26, 28.
  • the ribs 62 increase the strength and rigidity of the rail 16.
  • the receiver upper surface 38 may comprise one or more grooves 60 formed thereon.
  • the grooves 60 are configured to engage with the ribs 62.
  • two of the grooves 60 are formed on the receiver upper surface 38, on either side of the second lobe 46.
  • the grooves 60 are preferably sized and oriented to align with one of the ribs 62.
  • FIG. 5 depicts two of the units 12a, 12b; however, it is understood that the glare screen system 10 may include many more of the units 12.
  • the first end 22b of the unit 12b overlaps somewhat with the second end 24a of the unit 12a, with the receiver portion 34a placed through the slot 64b.
  • the ledges 52b and the projections 54a it may be necessary to first force the sidewalls 20b slightly apart laterally (i.e. by pulling the sidewalls 20b apart) proximate to the first end 22b, as shown in Fig. 17. This allows the ledges 52b to slide past the proj ections 54a. Once the ledges 52b have slid past the projections 54b, the sidewalls 20a may be released, allowing them to revert to their original configuration. However, the receiver portion 34a will now be held in place within the slot 36b by the engagement of the ledges 52b with the projections 54a.
  • One of the caps 100b is then placed into the protrusion opening 96b.
  • One of the fasteners 50 is then applied through the cap floor opening 112, the protrusion floor opening 58b, and the receiver opening 48a to secure both the units 12a, 12b to the concrete barrier 2.
  • the fasteners 50 may compnse a concrete expansion anchor 128, which extends through the cap floor opening 112, the protrusion floor opening 58b, and the receiver opening 48a, and a nut 130 that threadably engages the anchor 128, as shown in Figs. 14 to 16.
  • the first and second lobes 44, 46 are substantially circular, with centers Cl and C2, respectively.
  • the distance between the centers Cl, C2 is approximately 1 inch.
  • the unit 12 has a length of approximately 1337mm, a width of approximately 150mm, and a height of approximately 620mm. However, it is understood that other dimensions for the unit 12 are also possible.
  • Fig. 18 depict a sectional view of the units 12a, 12b connected together. Because of the engagement of the protrusion 56b with the depression 42a and the engagement of the cap 100 with the protrusion 56b, there is effectively a triple layer of material that connect the units 12a, 12b together (i.e. such as the depression wall 82a, the third protrusion wall 90b, and the cap wall 108, or such as the depression floor 84a, the protrusion floor 94b, and the cap floor 110).
  • connection point between the units 12a, 12b increases the strength of the connection point between the units 12a, 12b, by helping the connection resist twisting or breakage when impacted (such as by a vehicle).
  • the connection between the units 12a, 12b is further strengthened by the engagement of the cap rim 106 with the protrusion channel 92b.
  • the paddles 14 are substantially hollow.
  • the paddles 14 may be integrally formed with the rail 16 to form the unit 12.
  • the region of the first and/or second faces 26, 28 proximate to where they meet with the upper surface 18 may preferably compnse thinned sections 132 that extend for at least a portion of the height of the first and/or second faces 26, 28, as shown in Figs. 15 and 16.
  • the first and second faces 26, 28 at the thinned sections 132 are thinner than the walls at other portions of the unit 12.
  • the thinned sections 132 promote the bending (or breaking) of the paddles 14 in the areas proximate to or at the thinned sections 132 when the paddles 14 are impacted.
  • the modular and stackable nature of the units 12 in the glare screen system 10 allows for flexibility in installing and removing the units 12. For example, once the units 12d, 12e, 12f are attached to the concrete barrier 2, it is possible to remove one of the units 12 (e.g. unit 12e as shown in Fig. 21) by removing the fasteners 50 associated with the unit 12e. The removed unit 12e can then be stacked on top of another of the remaining one of the units 12c, as shown in Fig. 22 (and described in more detail below). The concrete barrier 2 can also be moved (with the remaining units 12 still attached) using a barrier lift 6, as shown in Fig. 23. This allows the concrete barrier 2 to be moved without having to remove all of the units 12 from the concrete barrier 2.
  • a barrier lift 6 as shown in Fig. 23.
  • FIG. 24 concrete barriers 2 with the units 12 attached may be of different lengths.
  • Fig. 24 depicts concrete barriers 2a, 2b, 2c with lengths 20 feet, 12.5 feet, and 12 feet, respectively.
  • the concrete barriers 2a, 2b, 2c may be stored side by side, with the units 12 still attached.
  • Figs. 25 to 28 because of the tapered nature of the paddles 14, the angle formed by opposing paddle ends 63 of adjacent ones of the paddles 14 changes along the height of the paddles 14.
  • Figs. 26 to 28 depict cross-sectional views of the unit 12 at different heights along the paddles 14 (i.e. at heights HI, H2, H3 of Fig. 25).
  • paddles 14a, 14b on the unit 12 have opposing paddle ends 63a, 63b.
  • Lines LI, L2, L3 connect the paddle end 63a with the paddle end 63b at heights HI, H2, H3, respectively.
  • L2, L3 form angles Bl, B2, B3 with the longitudinal axis 30.
  • the angle Bl is approximately 22.25°
  • the angle B2 is approximately 27.17°
  • the angle B3 is approximately 32.95°.
  • the angle Bl corresponds to a height proximate to the upper paddle surface 66
  • the angle B2 corresponds to a height at a midpoint of the paddle 14
  • the angle B3 corresponds to a height proximate to the attachment of the paddle 14 to the upper surface 18.
  • the headlights from oncoming vehicles may be visually blocked by the paddles 14 to a greater degree than compared to higher parts of the same vehicles (which may be visually blocked by the paddles 14 to a lesser degree as they would correspond to being higher up through the paddles 14).
  • the units 12 may be stacked vertically.
  • the paddles 14 of one of the units 12 may be inserted over the paddles 14 of the second one of the units 12.
  • the upper paddle surface 66 comprises one or more protruding stops 68 (seen in Fig. 12) that extend into the paddle enclosure 65. The stops 68 prevent the units 12 from sticking together when stacked. This sticking together or adherence of the units 12 may make later separation of the units 12 much more difficult.
  • the stops 68a on the unit 12a would come into contact with the upper paddle surface 66b on the unit 12b and prevent the paddles 14a from any further downward movement with respect to the paddles 14b.
  • the amount of contact between the first and second faces 26a, 26a of the paddles 14a and the first and second faces 26b, 28b of the paddles 14b is limited, thus reducing the likelihood of the paddles 14a, 14b sticking or adhering to each other.
  • FIG. 29 depicts one possible arrangement of the units 12, with eight rows 70 of the units 12 arranged in a side-by- side configuration, with each of the rows 70 comprising nine of the units 12 stacked on top of each other.
  • one or more straps 72 may be provided.
  • the straps 72 are generally planar and comprise a plurality of strap openings 74.
  • the strap openings 74 are configured to engage with the paddles 14.
  • the strap openings 74 are preferably sized so that the paddles 14 are able to pass through (at least partially) the strap openings 74.
