  • Patent number: 5732911
    Abstract: A legless sign stand includes a rubber base having an upper planar surface and a lower planar surface. A first rigid planar member contacts the upper planar surface of the rubber base, and a second rigid planar member contacts the lower planar surface of the rubber base. Both of the rigid planar members are secured to the rubber base with bolts. Two support brackets are mounted to the first rigid planar member, and a support mast is connected between the two support brackets. The support mast accommodates a clamping member, which is adapted for clamping onto a portion of the highway traffic sign to thereby support the highway traffic sign above a horizontal support surface.
