Traffic channeling device
First Claim
1. A traffic channeling device comprising a delineator stem including hollow upper and lower portions, the upper portion being stepped inwardly along its axial length to form sequential stepped surfaces from bottom to top of the upper portion, and the lower portion being frustoconically shaped to provide a substantially larger outer diameter adjacent a bottom end of the lower portion than at a top end of the lower portion, the lower portion having a bottom flange at the bottom end to resist pull out of the delineator stem from a ring-shaped base member when inserted over the delineator stem to act as a ballast for the delineator stem, the lower portion being sufficiently flexible that upon impact of the upper portion by a vehicle, the lower portion will collapse sufficiently to permit the bottom flange to pull through the base member to disengage the delineator stem from the base member, the stepped surfaces on the upper portion providing added rigidity and strength to the upper portion, making the upper portion better able to withstand the impact of a vehicle without deforming.

Abstract
Traffic channeling device includes a delineator stem having hollow upper and lower portions, the upper portion being stepped inwardly along its axial length to form sequential stepped surfaces from the bottom to the top of the upper portion, and the lower portion being frustoconically shaped. Adjacent the bottom of the delineator stem is a radial flange portion which resists pullout of one or more ring-shaped base members placed over the top of the delineator stem to act as ballast for the delineator stem. The base members include a non-circular raised portion and a correspondingly sized recessed portion such that when one base member is stacked on top of another, the recessed portion of one base member will receive the raised portion of the other base member and resist relative rotatable movement between the base members.

A traffic channeling device comprising a delineator stem including hollow upper and lower portions, the upper portion being stepped inwardly along its axial length to form sequential stepped surfaces from bottom to top of the upper portion, and the lower portion being frustoconically shaped to provide a substantially larger outer diameter adjacent a bottom end of the lower portion than at a top end of the lower portion, a base member having an opening permitting the base member to be inserted over the delineator stem to act as ballast for the delineator stem, the delineator stem having a bottom flange at the bottom end to resist pullout of the delineator stem from the base member, the lower portion of the delineator stem being sufficiently flexible that upon impact of the upper portion by a vehicle, the lower portion will collapse sufficiently to permit the bottom flange to pull through the base member to disengage the delineator stem from the base member, the stepped surfaces on the upper portion providing added rigidity and strength to the upper portion, making the upper portion better able to withstand the impact of a vehicle without deforming.
- 15. A base member for ballasting a delineator stem of a traffic channeling device, the base member including an opening extending through the base member adapted to receive a delineator stem, the base member including a top surface having a noncircular raised portion, and a bottom surface having a correspondingly sized recessed portion shaped to receive the raised portion and to substantially resist relative rotatable movement between one bas e member and another base member when one base member is stacked on top of another base member.
