Abstract
Abstract A portable base is described for supporting driveway reflectors, signs, etc. mounted atop relatively thin standards. The base comprises a cylindrical container open at one end and adapted to stand in an upright position with its closed end resting on any generally flat surface. An interior frame including spaced apart, concentrically aligned inner rings through which the standard of the reflector passes is secured inside the container. With the standard inserted in the supporting rings, the container is filled with sand or other high density material to maintain it in an upright position. If struck by a vehicle, it will tip over without damage to the sign and can be righted easily. The base is easily moved to desired locations and can be readily stored when not in use.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
155 words
For use in a supporting base for an elongated vertical rod, which base includes a generally cylindrical container open at one end and adapted to stand on its other, closed end, and receive a quantity of relatively high density material, a frame for supporting said rod in an upright position within said container comprising a pair of support members, each of which includes an outer ring of a diameter to be snugly received in said container, an inner ring of a diameter to freely receive said rod, and a plurality of radially extending arms interconnecting said inner and outer rings and supporting them relative to each other, a plurality of spacer elements fastened to the respective outer rings of said frame members to maintain said members rigidly spaced from each other with said inner rings in aligned relationship, said rings, arms and spacer elements being formed of a wirelike material of relatively small cross-sectional area.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
42 words
The frame according to claim 1 wherein said spacer elements extend beyond the plane of one of said members whereby said element extensions maintain the adjacent frame member spaced from the closed end of said container when the frame is inserted therein.
Claim 4
Dependent Claim
32 words
The frame according to claim 1 wherein the diameter of said outer ring is such as to retain said member firmly in place within said container after being wedged into desired position.
