Abstract
A safety delineator is provided having either a conical or a tubular body portion, which has an improved handle feature permitting easy and comfortable full hand gripping of the delineator. The invention additionally solves a longstanding problem common to prior art support bases for delineators and the like, by providing a convenient handle, molded integrally with the support base element, for picking up the base. The inventive handle not only provides a convenient means for grabbing the delineator, but it also provides an additional advantage with respect to conical delineators, in that it prevents them from sticking together when they are stacked. Two types of inventive support bases are disclosed. One is a base molded from a heavy solid material, such as rubber, and includes additional advantageous features such as anti-skid grippers on the bottom surface of the base element and stacking rings molded onto the upper surface of the base element for assisting in compactly stacking a plurality of bases. The second type is molded from resilient plastic, and adapted to be filled with a ballast material such as sand. This base is advantageously molded to provide a funnel structure for filling the ballast chamber, which, after the filling step is completed, is cut off. The base element edges are then sealed to permanently seal the ballast chamber. Additional features of this type of base are its dome-like configuration and the provision of corrugations on its bottom surface, both of which contribute to its crush resistance.
