Abstract

A traffic barricade or marker comprises a base in the form of a conventional pneumatic vehicle tire having a pair of substantially vertical flexible plastic tubular posts upstanding from the tire upper sidewall from aperture means located diametrically across from each other. The tubular posts in their unflexed condition are substatntially straight and upwardly diverging in a symmetrical manner away from the tire principal axis. A substantially rectangular structural member has a pair of longitudinally spaced tubular-like connector formations thereon of a size to be freely telescoped over the upper end portions of said posts. The structural member has a predetermined major dimension between its connector formations so as to continually flex the upper end portions of the posts into substantial parallel relation whereby said connector formations are releasably retained on the posts. As a result, each of the lower end portions of the posts are urged into contact with an edge of its associated tire aperture means to frictionally retain the posts within the tire. The structural members may be either flexible banners or figid rail members while the tire may be filled with buoyant material for use in the invention as a floatable marine traffic marker or buoy. A further disclosed alternative uses wood boards as the base with the banners flexing the posts toward each other and a rigid top rail forcing their upper ends apart.
