Abstract
A deformable, detachable base for supporting and stabilizing an attached vertical sign or delineator in upright orientation with respect to a ground or road surface to which the base may be affixed. The detachable base includes a deformable, domed structure comprised of a top, intermediate body wall and base attachment channel. The base attachment channel includes first and second channel walls, and a third radial flange which projects inward from the second channel wall toward a central axis of the domed structure. Accordingly, three (3) enclosing walls define a channel enclosure which is utilized to retain the domed structure in attachment to a rigid base plate. The base plate has a vertically oriented lip at its perifery which is adapted in size and configuration for a tight, contour fit within the channel enclosure. The inventive structure enables easy attachment and removal of the domed structure to the base plate during non-impacting conditions; however, the same domed structure responds to vehicle impact by gripping more tightly at the base plate lip to thereby hold its attached condition despite high speed vehicular impact.
