Abstract
A plurality of closely spaced and pivotally interconnected divider sections form a roadway lane divider and barrier. The divider sections are adapted to be lifted and transferred on a roadway as a unit. A plurality of releasable locking members are reciprocally mounted on respective pairs of the divider sections to either lock them together against relative pivotal movement or to selectively release the locking members to permit the divider sections to freely pivot relative to each other when they are lifted for transfer purposes.
Claims11
A transferable roadway lane divider comprising
- a plurality of upstanding divider sections, each having a base and an upper end, disposed in closely spaced and tandem relationship relative to each other to form a barrier,
- connecting means for pivotally connecting adjacent divider sections together for permitting them to pivot laterally relative to each other,
- transfer means formed in unobstructed relationship longitudinally throughout the entire length of the upper end of each divider section and aligned with the transfer means of a next adjacent divider section for receiving a common transfer apparatus to permit said divider sections to be lifted and suspended above a roadway for transfer thereon,
- lock means longitudinally bridging and engaging at least one pair of said divider sections for preventing them for pivoting laterally relative to each other, and
- guide means for reciprocally mounting said lock means for vertical movements on at least said pair of divider sections to selectively release said lock means from engagement with said pair of divider sections to permit said pair of divider sections to pivot laterally relative to each other.
