  • Patent number: 4232466
    Abstract: Apparatus for holding a display panel such as a warning sign is the subject of the present invention. The apparatus is particularly designed for use as a barricade in the vicinity of road construction. The apparatus is constructed of standard plastic tubing and fittings of the type used in the plumbing industry. A break-away construction minimizes damage in the event an object strikes the apparatus and makes repair quick and economical. Four tubular leg supports are arranged in two converging pairs and are each presented by tubular members held together by a standard T-coupling. Standard Y-couplings join the two pairs of leg supports at their point of convergence. First and second transverse tubular members extend between the T-couplings on the respective pairs of legs and each of the transverse members is of a length equal to twice the length of the members which form the legs. This permits the two leg sections to be made by simply dividing a transverse segment into half.
