Abstract
Abstract An assembly for mounting a face shield on a protective hard hat. The assembly has an arcuate support member which defines channel portions at least in the region of its two ends. A correspondingly shaped arcuate frame member is pivotally mounted with respect to the support member. The frame member is adapted to secure a depending face shield therefrom. The frame member and face shield are mounted on a hard hat by the support member with a pair of elongate blocks which are insertable within the channel portions of the support member. The elongate blocks are fastened to opposed exterior sidewalls of the hard hat. Also included are releasable retainer means at a fixed location therealong when the blocks are fastened to the hat.
