Abstract

A blow-molded plastic, traffic control barricade. The assembly provides a hollow, blow-molded, louvered upright panel outfitted with warning indicia, lights and/or air passages that pivots from a molded hollow base. Braces mount between the base and upright panel. The panel and braces fold into a recessed cavity in the base and present a collapsed shape that occupies relatively little space and lends itself to stacking and erection and dismantling.

Claims

1. A molded plastic barricade, comprising:

a) a rectangular base panel having a bottom wall and a plurality of side walls that project from said bottom wall to define a cavity space, wherein said bottom and side walls include seamless, hollow cavities and wherein said side walls include a plurality of recesses; and

b) a rectangular marker panel having a seamless, hollow core coupled at hinge means to said base panel to pivot between a storage condition wherein said marker panel folds into said cavity space and an upright condition wherein said marker panel spans a substantial width of a traffic lane on a roadway, wherein said marker panel includes front and rear walls, wherein said front wall is defined by a plurality of ledges that project transverse to said rear wall and a plurality of tapered surfaces that extend between a forward most edge of one of said ledges to an innermost edge of an adjoining ledge to present a louvered appearance, wherein said front wall includes indicia visible to observers, and wherein a plurality of apertures extend through said marker panel at said tapered surfaces to permit air to pass through said marker panel; and

c) a brace hinged to said marker panel and selectively mountable in one of said plurality of recesses at said side walls for securing the marker panel in said upright condition.

2. A barricade as set forth in claim 1 including first and second braces, wherein said marker panel includes recesses for storing said first and second braces and wherein said first and second braces are hinged at one end to one of said marker panel and an opposite end interlocks with a selected one of said plurality of recesses at said side walls.

3. A barricade as set forth in claim 2 wherein said base panel includes means for filling and draining a ballast material from said hollow core of said base panel.

4. A barricade as set forth in claim 1 wherein said marker panel includes a recess for storing said brace.

5. A barricade as set forth in claim 1 wherein said marker panel includes a light source and means for controlling the illumination of said light source.

6. A barricade as set forth in claim 1 including a plurality of elongated members, wherein said side walls include apertures for receiving said elongated members, and wherein said elongated members extend to interconnect to the side walls of a base panel of an adjacent barricade of identical construction.

7. A barricade as set forth in claim 1 wherein the bottom wall of said base includes a plurality of apertures for draining liquid collecting in said cavity space.

8. A molded plastic barricade, comprising:

a) a base panel having a bottom wall and a plurality of side walls that project from said bottom wall to define a cavity space, wherein said bottom and side walls are hollow and wherein said side walls include a plurality of recesses; and

b) a marker panel having a hollow core coupled at hinge means to said base panel to pivot between a storage condition wherein said marker panel folds into said cavity space and an upright condition wherein said marker panel spans a substantial width of a traffic lane on a roadway, wherein said marker panel includes front and rear walls, wherein said front wall is defined by a plurality of ledges that project transverse to said rear wall and a plurality of tapered surfaces that extend between a forward most edge of one of said ledges to an innermost edge of an adjoining ledge to present a louvered appearance, and wherein said front wall includes indicia visible to observers; and

c) a brace mounted to said marker panel and selectively mountable in one of said plurality of recesses at said side walls for securing the marker panel in said upright condition.

9. A barricade as set forth in claim 8 wherein said marker panel includes a light source and means for controlling the illumination of said light source.

10. A barricade as set forth in claim 8 wherein said marker panel includes recesses for storing said brace.
