Roadway barrier apparatus
Roadway barrier apparatus including roadway barrier modules disposed end to end and pivotally connected together by a pivot pin positioned in aligned apertures of connector brackets at the ends of the modules, the pivot pin having a groove and a spring biased hinge pusher member positionable in the groove to limit upward movement of the pivot pin.
1. Roadway barrier apparatus comprising, in combination:
a first roadway barrier module having a double-ended first module body and upper and lower first module connector brackets extending from each end thereof, said upper and lower first module connector brackets spaced a fixed vertical distance from one another and defining aligned first module bracket apertures, said upper and lower first module connector brackets affixed to said first roadway module and immovable relative thereto;
a second roadway barrier module having a double-ended second module body and upper and lower second module connector brackets extending from each end thereof, said upper and lower second module connector brackets spaced from one another and defining aligned second module bracket apertures, said upper and lower second module connector brackets affixed to said second roadway module and immovable relative thereto, the first module body and the second module body being disposed with opposed ends thereof spaced from one another and the upper first and second module connector brackets thereof in overlapping relationship and the lower first and second module connector brackets in overlapping relationship with the first module bracket apertures and the second module bracket apertures aligned;
an assembly including a guide structure disposed in a cavity formed in said first module body and further including a spring biased hinge pusher member within said guide structure slidably connected to the first module body extending from the first module body toward the second module body and continuously biased toward the second module body; and
a pivot pin positioned between said first module body and said second module body in said aligned apertures of said first and second module body connector brackets and extending through said upper and lower first and second module connector brackets, said pivot pin having a circumferentially extending groove defined by upper and lower circular chamfered surfaces, said pivot pin including a pivot pin top portion above the topmost upper module connector bracket and said spring biased hinge pusher member positioned in said circumferentially extending groove to limit upward movement of said pivot pin and prevent disengagement of said pivot pin from said overlapping upper and lower connector brackets due to ratcheting effect caused by relative motion between the first and second roadway barrier modules, said pusher member having a pin contact surface engaging said pin between said upper and lower circular chamfered surfaces.
2. The roadway barrier apparatus according to claim 1 including a guide projection attached to the hinge pusher member slidable in a slot in the guide structure.
