Abstract

A highway barricade which has an appearance similar to that of a large steel drum is formed of an organic polymer. The sidewalls of the barricade are slightly tapered to permit the nesting together of a plurality of similar units, and the base portion thereof is provided with weighting means to permit it to withstand normal forces encountered in highway situations. Visibility of the device is enhanced by incorporating fluorescent, phosphorescent and/or reflective materials in the polymer; by providing faceted surfaces; and/or by locating a light source inside a translucent barricade.

Claims

1. A highway barricade comprising

a main body having upright sidewalls symmetrically arranged about a central vertical axis, said sidewalls having opposed portions horizontally spaced about 2 feet apart, said sidewalls converging upwardly toward said axis to permit nesting of a plurality of identical main bodies,

weighting means connected to a lower portion of the main body to stabilize the barricade and prevent its tipping when subjected to horizontally directed forces, said weighting means being a trough substantially coextensive with the sidewalls for receiving a weighting material, said trough being open upwardly to the interior of the barricade and having an inner wall inclined upwardly and inwardly, with the extent of inward extension of said inner wall being less than that which would contact the entire periphery of an identical barricade nested therewithin, and a stop means for supporting an identical unit nested thereon to prevent wedging together of the sidewalls.

2. The highway barricade of claim 1 having an upper wall provided with receptacle means for receiving a housing of a light flasher unit.

3. The barricade of claim 1 wherein said upright sidewalls are provided with a plurality of faces which are oriented to reflect rays of light.

4. A highway barricade comprising,

a main body having upright sidewalls symmetrically arranged about a central vertical axis, said sidewalls having opposed portions horizontally spaced about 2 feet apart, said sidewalls converging upwardly toward said axis to permit nesting of a plurality of identical main bodies,

weighting means connected to a lower portion of the main body to stabilize the barricade and prevent its tipping when subjected to horizontally directed forces, said weighting means being a trough substantially coextensive with the sidewalls for receiving a weighting material, said trough being open upwardly to the interior of the barricade and having a stop means for supporting an identical unit nested thereon to prevent wedging together of the sidewalls, said stop means being a horizontal flange located directly above the trough, said trough having an outer wall connected to the outer edge of the horizontal flange.

5. The highway barricade of claim 4 having an upper wall provided with receptacle means for receiving a housing of a light flasher unit.
