Abstract
Molded ribs are provided for use in connection with traffic channeling devices, such as drums, which employ external ballasting collars, such as molded rings or truck tire rings. The ribs are disposed at spaced intervals near the bottom of the external wall of the drum, for improving contact between the drum wall and the internal diameter of the ballasting collar, in order to eliminate undesirable separation of the drum and collar during ordinary use, and to prevent inadvertent rotation of the drum relative to the collar.
Claims23
A traffic channeling drum, comprising:
- a wall having an outside surface and an inside surface and terminating at a lower end in a base flange having a top surface;
- a ballasting collar disposed about said wall and over said base flange;
- and
- a plurality of integrally molded ribs disposed on said wall outside surface above said base flange;
- said molded ribs being spaced relative to one another about a periphery of said wall outside surface, in contact with a portion of said ballasting collar, wherein distances between adjacent ones of said integrally molded ribs vary in length.
A traffic channeling drum, comprising:
- a wall having an outside surface and an inside surface and terminating at a lower end in abase flange having a top surface, said base flange extending about substantially all of a periphery of said wall outside surface;
- and
- a plurality of integrally molded ribs disposed on said wall outside surface directly above said base flange;
- said molded ribs being spaced relative to one another about said periphery of said wall outside surface, wherein said plurality of integrally molded ribs are not spaced equidistantly about said periphery.
A traffic channeling drum, comprising:
- a wall having an outside surface and an inside surface and terminating at a lower end in a base flange having a top surface, said base flange extending about substantially all of a periphery of said wall outside surface;
- and
- a plurality of integrally molded ribs disposed on said wall outside surface directly above said base flange;
- said molded ribs being spaced relative to one another about said periphery of said wall outside surface, wherein distances between adjacent ones of said plurality of integrally molded ribs vary in length.
A traffic channeling drum, comprising:
- a wall having an outside surface and an inside surface and terminating at a lower end in a base flange having a top surface;
- a ballasting collar disposed about said wall and over said base flange;
- and
- a plurality of integrally molded ribs disposed on said wall outside surface above said base flange, said plurality of integrally molded ribs being spaced relative to one another about a periphery of said wall outside surface, but not being equidistantly spaced thereabout, in contact with a portion of said ballasting collar.
A traffic channeling drum, comprising:
- a wall having an outside surface and an inside surface and terminating at a lower end in a base flange having a top surface;
- and
- a plurality of integrally molded ribs disposed on said wall outside surface above said base flange;
- said molded ribs being spaced relative to one another about a periphery of said wall outside surface, wherein distances between adjacent ones of said plurality of integrally molded ribs vary in length.
