摘要:
A road warning system for indicating the presence of emergency or other conditions along a roadway or other surface includes an elongated carrier and a plurality of erectable-retractable warning means which are retracted when the carrier is disposed in a storage mode and erected when the carrier is translated from the storage mode into the utilization mode in which the warning means are erected to indicate the existence of a roadway anomaly. The carrier may consist of a wide variety of different structures, including linkages, continuous lengths of flexible-deformable material and the like. It is also contemplated that the carrier will incorporate various conductors, including electrical and fluid conductors, so that the warning means may be illuminated either electrically or by means of illuminating gases.
