Abstract
Abstract Roadway traffic and/or warning signs are provided with the construction thereof being such so as to provide flexible and/or pliable structures which are simultaneously lightweight for easy handling, but are of substantial strength. The signs of the invention are, preferably, comprised of molded polyurethane foam of integral structure which will give upon impact without damage, and will revert to their previous position once the forces causing the impact are removed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
237 words
A traffic sign for roadways, comprising (a) a weighted base; (b) a substantially rectangular, one-piece, flat sign portion comprised of a molded pliable polymer of relative low specific gravity and of relative high strength; (c) vertical tube means connecting said base to said sign portion; (d) said vertical tube means including (1) a cylindrical flexible adapter; (2) a first vertical tube extending from said weighted base to said adapter; (3) a second vertical tube extending from said sign portion to said adapter; (4) spaced coaxial blind bores in said adapter for receiving said first and second vertical tubes; (5) an annular locking clip receiving groove in the outer surface of said adapter adjacent the top thereof; (e) integral vertical reinforcing rib means extending adjacent to the longitudinal axis of said sign portion; (f) a pair of spaced transverse integral reinforcing ribs extending laterally from the rear surface of said sign portion; (g) coaxial bores in said spaced transverse ribs, said coaxial bores in the said longitudinal axis of said sign portion; (h) said coaxial bores receiving said second vertical tube; (i) a continuous integral molded edge reinforcement extending from both faces of said flat sign portion; (j) a bore in each of the vertical portions of said edge reinforcement; (k) elongated flexible reinforcing means extending in said vertical bores; and (l) a space in said flat sign portion for containing electrical connection means for said warning light.
Claim 2
Dependent Claim
237 words
A traffic sign for roadways, comprising (a) a weighted base; (b) a substantially rectangular, one-piece, flat sign portion comprised of a molded pliable polymer of relative low specific gravity and of relative high strength; (c) vertical tube means connecting said base to said sign portion; (d) said vertical tube means including (1) a cylindrical flexible adapter; (2) a first vertical tube extending from said weighted base to said adapter; (3) a second vertical tube extending from said sign portion to said adapter; (4) spaced coaxial blind bores in said adapter for receiving said first and second vertical tubes; (5) an annular locking clip receiving groove in the outer surface of said adapter adjacent the top thereof; (e) integral vertical reinforcing rib means extending adjacent to the longitudinal axis of said sign portion; (f) a pair of spaced transverse integral reinforcing ribs extending laterally from the rear surface of said sign portion; (g) coaxial bores in said spaced transverse ribs, said coaxial bores in the said longitudinal axis of said sign portion; (h) said coaxial bores receiving said second vertical tube; (i) a continuous integral molded edge reinforcement extending from both faces of said flat sign portion; (j) a bore in each of the vertical portions of said edge reinforcement; (k) elongated flexible reinforcing means extending in said vertical bores; and (l) a space in said flat sign portion for containing electrical connection means for said warning light.
