Abstract
Abstract The detachable safety warning device invention utilizes posts with weighted feet connected by rod or cable spanning the distance between said posts with socketed connected tubular pipe bodies having longitudinal slots running the full length of each pipe to enable the quick assembly of same over said rod or cable and quick detaching of said pipes from said rod or cable stretched between said posts. The device is used to locate across roads in repair or under construction with writings and/or colored safety warning displays painted on or attached to a single pipe or a series of pipes joined together and mounted on said rod or cable. Said pipes, preferably, are to be made of plastic or other suitable light weight material. Thus, is an oncoming vehicle on the roadway did by accident collide with safety warning device it would not cause any damage or very slight damage to the vehicle or the driver and passengers therein. The feet on the posts are weighted with water, dirt or other easily accessible materials which may be dumped when said device is to be moved to another location. Said feet are open at their tops so that the weighted materials may be dumped therefrom and said device may be dis-assembled, handled and transported to another location for use in a facile manner.
