Abstract
Abstract A guidepost for roadways or the like comprising an elongated tubular member formed from a flexible plastic material having a substantially "T"-shaped, cross-sectional configuration throughout the length thereof, the forward or front wall being relatively flat across its face and integrally formed, with sinusoidal-shaped side walls and a semi-circular rear wall defining the base of the "T"-shaped configuration, the forward wall having affixed adjacent one end thereof a reflector member. The lower, inner tubular section includes a filler core to provide and maintain its cross section below the ground line, the lower terminating end of the guidepost including a base member defined by an annular flange member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
112 words
A guidepost structure, the combination comprising an elongated, tubular-body member of pliable plastic material, and said member having: a front wall of substantial width; a rear wall; and a pair of side walls having a sinusoidal configuration, said side walls integrally connecting said front and rear walls; wherein said front wall is substantially flat throughout the length thereof, and said rear wall is semi-circular throughout its length thereof; said front wall, said side walls, and said rear wall defining a "T"-shaped, horizontal, cross-sectional configuration; and wherein said elongated tubular body includes a memory factor whereby any distortion of said walls will slowly be corrected so that they can attain their original contour.
Claim 2
Dependent Claim
112 words
A guidepost structure, the combination comprising an elongated, tubular-body member of pliable plastic material, and said member having: a front wall of substantial width; a rear wall; and a pair of side walls having a sinusoidal configuration, said side walls integrally connecting said front and rear walls; wherein said front wall is substantially flat throughout the length thereof, and said rear wall is semi-circular throughout its length thereof; said front wall, said side walls, and said rear wall defining a "T"-shaped, horizontal, cross-sectional configuration; and wherein said elongated tubular body includes a memory factor whereby any distortion of said walls will slowly be corrected so that they can attain their original contour.
Claim 3
Dependent Claim
26 words
A guidepost structure as recited in claim 1, wherein said tubular body member includes an annular flange member integrally formed at the lower terminated end thereof.
Claim 4
Dependent Claim
32 words
A guidepost structure as recited in claim 2, wherein said front wall forms a head portion of said "T"-shaped configuration, and said side walls and rear wall define a base portion thereof.
Claim 5
Dependent Claim
66 words
A guidepost structure as recited in claim 3, wherein said sinusoidal side walls comprise: a convexed portion contiguously joined to said front wall; and a concaved portion contiguously joined to said rear semi-circular wall whereby an accordion-type folding is effected when said tubular body is subjected to impact forces from a vehicle, and wherein said body is allowed to bend without additional stress being applied thereto.
Claim 6
Dependent Claim
23 words
A guidepost structure as recited in claim 4, wherein said guidepost includes a reflector means attached to the upper end of said body.
Claim 7
Dependent Claim
51 words
A guidepost structure as recited in claim 5, wherein said reflector means comprises: a plurality of reflector elements secured to the upper end of said body; a securing bar member positioned within said body member; and securing means attaching said elements to said guidepost, and mounted to said securing bar member.
Claim 8
Dependent Claim
50 words
A guidepost structure as recited in claim 5, wherein said reflector means comprises: a mounting-plate member; a plurality of reflector elements secured to said mounting-plate member; a securing bar member positioned within said body member; and securing means attaching said mounting plate to said guidepost and said securing bar member.
Claim 9
Dependent Claim
52 words
A guidepost structure as recited in claim 5, wherein the lower portion of said tubular-body member is filled with a core member to prevent that portion thereof from collapsing under stress when disposed within the surrounding ground medium, the core being arranged to terminate below the ground level of said ground medium.
