Abstract:

A portable sign assembly includes one or more sign supports attached to the outer surface of a flexible band that may be adjustable to fit different diameter drums. Each sign support may have a substantially planar front face to facilitate attachment of a panel assembly to the sign support. The panel assembly may comprise one or more sign panels.

US Classification:

404 6, 404 9, 256 131

Abstract:

A barrier includes a housing having a front wall and an opposing back wall each extending between opposing sidewalls. The housing also includes a floor and an interior surface bounding a chamber, the chamber communicating externally through an inlet opening. A first inset projects into the chamber from the front wall so as to form a recessed blind pocket on the front wall. A second inset projects into the chamber from the back wall so as to form a recessed blind pocket on the back wall. The first inset and the second inset are connected together within the chamber so that the chamber encircles the connection.

International Classification:

E04H 1714

US Classification:

256 19

Abstract:

Plastic fencing has a plurality of openings therein and one or more strips of reflective tape applied to one or both sides of the fencing to make the fencing more visible under poor lighting conditions as when used as a visual warning barrier around construction sites and the like. To secure the reflective tape to the fencing, the reflective tape is adhered to one side of the fencing in overlying relation to some of the openings therein, and to a plastic backing applied to the opposite side in line with the reflective tape through the openings in the fencing.

US Classification:

116 63C

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.
