  • Display sign with collapsible support base
    Patent number: 5371964
    Abstract: A display sign with a collapsible support base. The sign is supported by at least one upwardly extending leaf of a hinge element to which a pair of support legs are attached extending both in front of and behind the sign. When the support legs are extended outwardly and the base is supported on a weight-bearing surface, the legs at each end portion of the sign pivot about the hinge element to exert a pincer-like grip on the bottom portion of the display sign. When the sign is lifted up, the support legs fold down automatically into a compact form suitable for transport or storage.
