Anchorless crash cushion apparatus with midnose stabilizing structure
An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of an impacting vehicle and ramping of the impacting vehicle and stabilizing structure including a midnose structure resisting relative rotation between crash cushion elements in both vertical and lateral planes during vehicle impact.
1. Anchorless crash cushion apparatus comprising in combination:
a plurality of crash cushion elements including interconnected water-filled crash cushion elements and a forward element;
vehicle capture structure operatively associated with said forward element operable to capture a vehicle frontally impacting the forward element, resist upward tilting of the impacting vehicle and substantially prevent ramping of the impacting vehicle over the forward element; and
stabilizing structure including a midnose structure operatively associated with said plurality of crash cushion elements to resist relative rotation therebetween in both vertical and lateral planes during vehicle impact, each of said crash cushion elements having an element front, an element back, an element bottom, an element top and element sides, said midnose structure engaging the element back of said forward element and engaging the element front of the adjacent crash cushion element, said midnose structure comprising a vertical midnose member extending upwardly from a horizontal midnose member, said vertical midnose member positioned behind said forward element and in front of said adjacent crash cushion element, and said horizontal midnose member positioned under at least a portion of said forward element.
2. The anchorless crash cushion apparatus of claim 1 wherein said midnose structure is of metal construction.
3. The anchorless crash cushion apparatus of claim 1 wherein the element back of said forward element includes spaced rear connector projections defining a connector recess and a stabilizing member between the spaced rear connector projections, said vertical midnose member including a midnose connector protrusion defining a notch receiving said stabilizing member.
4. The anchorless crash cushion apparatus of claim 3 wherein said midnose structure includes an upper panel located above said midnose connector protrusion positioned over a portion of said forward element.
5. The anchorless crash cushion apparatus of claim 3 wherein said midnose connector protrusion defines a midnose connector recess for receiving a connector protrusion extending from said adjacent crash cushion element.
6. The anchorless crash cushion apparatus according to claim 1 including connector pins and metal straps securing said midnose structure to said forward element.
7. The anchorless crash cushion apparatus according to claim 1 wherein said midnose structure additionally includes side panels extending upwardly from said horizontal midnose member.
