DETAILED DESCRIPTION OF THE INVENTION

The following detailed description of the technology references the accompanying drawings that illustrate specific embodiments in which the technology can be practiced. The embodiments are intended to describe aspects of the technology in sufficient detail to enable those skilled in the art to practice the technology. Other embodiments can be utilized and changes can be made without departing from the scope of the current invention. The following detailed description is, therefore, not to be taken in a limiting sense. The scope of the current invention is defined only by the appended claims, along with the full scope of equivalents to which such claims are entitled.


An end plate 10, constructed in accordance with various embodiments of the current invention, for use with a roadway barrier 100 is shown in FIGS. 1-7. A plurality of roadway barriers 100 coupled to one another forms an intermediate section of a roadway barrier system 200, as shown in FIG. 5. The roadway barrier system 200 further includes a first end barrier 202 positioned at a first end, a second end barrier 204 positioned at a second end, and the intermediate section of roadway barriers 100 positioned therebetween—with the first end barrier 202 coupled to a first end of the intermediate roadway barriers 100, and the second end barrier 204 coupled to a second end of the intermediate roadway barriers 100.


Each roadway barrier 100, as shown in FIGS. 2, 4, and 5, includes a first end wall 102, a second end wall 104, two multilevel side walls 106, 108, a top wall 110, and a bottom wall (not shown in the figures). The roadway barrier 100 shown in the figures is merely exemplary, although in general, the roadway barrier 100 typically includes six walls coupled to one another to form a box shape. In other embodiments, the side walls may have a generally planar shape which leads to more rectangular shape of the end walls as compared to the roadway barrier 100 of the figures.


The end plate 10 includes a body wall 12, a first side flange 14, a second side flange 16, a first bottom flange 18, a second bottom flange 20, a first brace 22, and a second brace 24. The end plate 10 is implemented in one of two configurations. In a first configuration shown in FIGS. 1 and 2, the end plate 10-1 forms a portion of, or is integrated with, the first end wall 102 of the roadway barrier 100. In the first configuration, attached to the end plate 10-1 are a left bumper 112, a right bumper 114, and a first hinge assembly 116 that is a component of a solid hinge. In a second configuration shown in FIGS. 3 and 4, the end plate 10-2 forms a portion of, or is integrated with, the second end wall 104 of the roadway barrier 100. In the second configuration, attached to the end plate 10-2 are a second hinge assembly 118 and a pin 120 that are also components of the solid hinge 120. The components of the solid hinge shown in the figures are merely exemplary, and the end plate 10 may be utilized with a variety of roadway barrier hinge types and components.


The body wall 12 includes a front surface and a rear surface. The body wall 12 is further divided into a left section, a center section, and a right section, with the lines between the center section and the other sections being vertically oriented. In addition, the left section and the right section are each connected to the center section at a non-zero angle such that the rear surface is slightly concave and the front surface is slightly convex. In various embodiments, the edges of the body wall 12 may include additional features. For example, an upper edge of each of the left section and the right section may be angled upward towards the center section whose upper edge may be generally flat. A left edge and a right edge may each include extensions that couple with the first or second end walls 102, 104 of the roadway barrier 100. A lower edge may include a cutout along the left, center, and right sections which accommodates a wedge or other features of the roadway barrier 100.


The first side flange 14 is connected to the body wall 12 along a left edge of the left section and extends rearward, or roughly orthogonal, from the rear surface of the body wall 12. The second side flange 16 is connected to the body wall 12 along a right edge of the right section and extends rearward, or roughly orthogonal, from the rear surface of the body wall 12. The first side flange 14 and the second side flange 16 are each configured to couple with a successive one of the side walls of the roadway barrier 100. Each side flange 14, 16 may include one or more cutouts to accommodate fasteners, such as screws or bolts, on the side walls.


The first bottom flange 18 is connected to the body wall 12 along a bottom edge of the left section and extends rearward, or roughly orthogonal, from the rear surface of the body wall 12. The second bottom flange 20 is connected to the body wall 12 along the bottom edge of the right section and extends rearward, or roughly orthogonal, from the rear surface of the body wall 12. The first bottom flange 18 and the second bottom flange 20 are each configured to couple with the bottom wall of the roadway barrier 100.


Referring to FIGS. 6 and 7, the first brace 22 and the second brace 24, both individually and in combination, provide lateral, or side-to-side, strength for the body wall 12. The braces 22, 24 are each elongated, narrow, and thin. Exemplary embodiments of each brace 22, 24 has a length of approximately 21.75 inches, a width of approximately 1.125 inches, and a thickness of approximately 0.2 inches. Each brace 22, 24 is attached across the width of the rear surface of the body wall 12 extending orthogonally therefrom, with the first brace 22 being positioned approximately 5.6 inches from a top edge of the body wall 12 and the second brace 24 being positioned approximately 8.85 inches from the top edge of the body wall 12. Furthermore, as best illustrated in FIG. 7, each brace 22, 24 has a contoured shape that includes three sections to match or complement the contoured shape of the three sections of the rear surface of the body wall 12.


Each brace 22, 24 also includes a first notch 26 and a second notch 28 which provide an opening in the brace 22, 24 that allows the brace 22, 24 to bend at the notch 26, 28 locations. Each notch 26, 28 extends from a rear surface of the brace 22, 24 toward a forward surface of the brace 22, 24, where the brace 22, 24 is attached to the rear surface of the body wall 12—although each notch does not extend the entire width of the brace 22, 24. Each notch 26, 28 has a generally rectangular shape including opposing side surfaces and an end surface positioned therebetween with the side surfaces being roughly parallel to one another. The length of each side surface, and thus the depth of the notch 26, 28, is approximately 0.79 inches. The space between the side surfaces is approximately 0.2 inches. In other embodiments, the notch 26, 28 may have a V shape, wherein the side surfaces intersect one another and there is no end surface.


Referring to FIG. 7, the first notch 26 is positioned along the length of the brace 22, 24 in order to roughly align with an inner edge of the right bumper 114 on the front surface of the body wall 12. The second notch 28 is positioned along the length of the brace 22, 24 in order to roughly align with an inner edge of the left bumper 112 on the front surface of the body wall 12. During a vehicular impact with the roadway barrier system 200, the roadway barriers 100 generally travel from front to rear with forward roadway barriers 100 impacting rearward roadway barriers 100 in succession. Referring to FIG. 8, typically, the impact from a forward roadway barrier 100 on a rearward roadway barrier 100 occurs on the left bumper 112 and the right bumper 114. Each brace 22, 24 reacts by bending at each notch 26, 28 such that the notch 26, 28 widens, with the side surfaces of each notch 26, 28 moving away from each other to at least partially straighten the brace 22, 24. By having the notches 26, 28 of the brace 22, 24 widen in response to an impact on the left bumper 112 and the right bumper 114, the end plate 10 flattens and more easily collapses in a straight column.
