Universal dual-pivot face shield assembly for a hard hat
Abstract:
An improved face shield assembly universally fits to most hard hats and includes a dual-point pivot system which allows the face shield to be located in a “down” as-used position, an “up” as-used position and a “stowed” position above the hard hat. The improved face shield assembly includes three separate brackets, namely a main mounting bracket secured to the brim of a hard hat, a rotating bracket pivotably mounted to the main mounting bracket and a lens mounting bracket pivotably mounted to the rotating bracket. Spring-loaded struts stabilize and retain the lens mounting bracket in the as-used and stowed positions relative to the rotating bracket.
