ABSTRACT:
A safety stick for joggers and other pedestrians has a shaft with high reflectivity. A grip can be provided as one end of the shaft and a hard plastic cap at the other. A wrist strap is provided adjacent the grip, with a break away connection to the shaft. The high reflectivity of the shaft may be provided by reflective (e.g. silver) paint on the shaft covered with a coat of clear lacquer having reflective glass beads (e.g. microspheres at a ratio of about two parts beads to one part lacquer by weight). Alternatively, the shaft may be spirally wrapped with retroreflective tape and covered with a clear plastic tube (e.g. pvc shrink tubing). A clear lacquer is applied over the clear plastic shrink tube.
