ABSTRACT:
A protective lens shield (12) with a torsion adjustment system (3) and simple one-bolt mounting bracket clamp (1) for use with outdoor lighting fixtures. The protective lens shield is constructed of dual layers and thicknesses of polycarbonate sheets (12) which have ballistic containment properties. The bracket clamp (1), clamp bolt assembly (2), adjustment carriage bolt (3), threaded adjustment housing (4), and arm-shield adjustment arm (5) are constructed of steel with a galvanized coating for a corrosion resistant longer life. The hook-and-cable assembly (FIG. 2) is comprised of a hook (8), cable (9), and a cable assembly bolt (10) which is stainless steel corrosion resistant materials. The torsion flex system is enhanced by the adjustable torsion carriage bolt (3). This adjustment allows for a flex in the polycarbonate sheets allowing it to absorb the energy from objects attempting to penetrate the shield (12). The rubber grommets (11) allow for movement, yet they hold the polycarbonate sheets together to perform the task of an expansion joint. The hook-and-cable assembly (FIG. 2) allows for a custom attachment to the existing light lens cover (6A) no matter where the location of the interior gussets are positioned. This custom attachment allows this protection shield to adapt to any make or model cobra head street light. Similarly, the protective shield may be molded into a variety of configurations to protect the various lighting fixtures. This protective shield is lightweight, easily attached to the pole arm (13), and swings away for easy luminaire maintenance.
