Safety cone

Abstract

A device includes a cone having a cone first end with a flange, the cone extending to a cone second end. A base has a recess to mate with the flange of the cone. The base also has multiple base openings. A ring is shaped to fit on top of the flange and has multiple ring openings to mate with the base openings in a top of the base for releasably coupling the cone to the base.

         2 . The device of  claim 1  wherein the base has a key tab opening and the ring has a key tab configured to mate with the key tab opening such that the base openings and ring openings align. 
     
     
         3 . The device of  claim 2  wherein the flange of the cone has flange openings to mate with the ring openings and the base openings. 
     
     
         4 . The device of  claim 1  wherein the cone is formed of injection molded Polyethylene (PE). 
     
     
         5 . The device of  claim 1  wherein the cone includes a sleeve of reflective sheeting positioned between the cone first and second ends. 
     
     
         6 . The device of  claim 5  wherein the sleeve is between 4 and 6 inches in length. 
     
     
         7 . The device of  claim 5  wherein the reflective sheeting comprises 3M Control Devices Series 3910 Diamond Grade reflective sheeting. 
     
     
         8 . The device of  claim 5  wherein the sleeves are adhered to the cone via heat treating or primer. 
     
     
         9 . The device of  claim 1  wherein the base is weighted. 
     
     
         10 . The device of  claim 9  wherein a bottom of the base comprises indentations for structural integrity, and wherein at least one indentation includes reflective material. 
     
     
         11 . The device of  claim 10  wherein the reflective material comprises reflective glass beads adhered in the at least one indentation. 
     
     
         12 . The device of  claim 11  wherein the reflective glass beads comprise 3M All weather elements AW50S or uses ID 75-0301-7298-7. 
     
     
         13 . The device of  claim 11  wherein the reflective glass beads are adhered by translucent glue. 
     
     
         14 . The device of  claim 13  wherein the glue comprises 3M Hi-Strength  90  adhesive. 
     
     
         15 . The device of  claim 1  wherein the cone tapers in a conical shape from the cone first end to the cone second end. 
     
     
         16 . A device comprising:
 a cone having a cone first end with a flange, the cone extending to a cone second end;   a base coupled to support the cone above a top of the base, a bottom of the base having at least one indentation that includes a reflective material.   
     
     
         17 . The device of  claim 16  wherein the cone is formed of injection molded Polyethylene (PE). 
     
     
         18 . The device of  claim 16  wherein the cone includes a sleeve of reflective sheeting positioned between the cone first and second ends. 
     
     
         19 . The device of  claim 18  wherein the sleeve is between 4 and 6 inches in length, wherein the sleeves are adhered to the cone via heat treating or primer. 
     
     
         20 . The device of  claim 16  wherein the reflective material comprises reflective glass beads adhered in the at least one indentation.
