Abstract

A traffic channelizing device has a base unit made from the sidewalls of used car or other vehicle tires, using tread portions as a stabilizer between two sidewalls, wound spirally and having an outer band with a protruding loop which results in the resilient integral base unit having a significantly reduced propensity to roll when the device is overturned. The device has the advantages of being highly resistant in wind and impact, yet being readily removable and stackable with substantially less manpower and transportation space than for existing devices. If the central hole for the upper sidewall portion of the base unit is larger than that for the lower sidewall portion, the device retains the traffic safety feature of the base being separable from the body portion in the event of a high impact, even where the upper portion comprises more than one sidewall.

Claims

1. A base unit for use in association with a body portion of a traffic channelizing device, said base unit having a substantially circular lower base portion comprising a sidewall of a vehicle tire, said sidewall having an inner planar section and an integral outer curved section providing a substantially circumferential convex ground contacting surface, and a substantially circular upper base portion comprising a separate independent sidewall of a vehicle tire, said sidewall of said upper base portion having an inner planar section and an integral outer curved section, disposed to form an annular concave channel between said upper and lower base portions, and ballast means affixed within said annular channel.

2. A base unit as claimed in claim 1 wherein said upper and lower base portions have a central opening of unequal diameter.

3. A base unit as claimed in claim 1 wherein said ballast means comprises at least one tread portion of a least one vehicle tire.

4. A base unit as claimed in claim 3 wherein said at least one tread portion is wound in a spiral configuration and is secured as an integral unit by a securing means.

5. A base unit as claimed in claim 4 wherein said ballast means is affixed to at least one location within said annular channel means by a securing means.

6. A base unit as claimed in claim 4 wherein said ballast means further comprises an outer tread portion affixed to comprise at least one protruding loop portion.

7. A base unit as claimed in claim 6 wherein said upper and lower base portions have a central opening of unequal diameter.

8. A traffic channelizing device comprising a base unit and a separate body portion extending upwardly therefrom, said base unit comprising a substantially circular lower base portion comprising a sidewall of a vehicle tire, said sidewall having an inner planar section and an integral outer curved section providing a substantially circumferential convex ground contacting surface, and a substantially circular upper base portion comprising a separate independent sidewall of a vehicle tire, said sidewall of said upper base portion having an inner planar section and an integral outer curved section, disposed to form an annular concave channel between said upper and lower base portions, and ballast means affixed within said annular channel said body protion having a generally cylindrical portion extending upwardly from an integral outwardly projecting circumferential ground-engaging flange.

9. A traffic channelizing device as claimed in claim 8, wherein a central hole in said upper base portion provides substantial clearance around an adjacent wall of said body portion, and a central hole in said lower base portion forms an interference fit with lower extremity of said body portion at a predetermined location.
