Abstract:
An improved face protector of a type having a head-engaging strap, a forehead engaging-stiffening member, a facing protecting-lens, and pivoting apparatus. The improvement includes the pivoting apparatus including a pair of studs that extend outwardly through associated pivoting-throughbores in the head-engaging strap, outwardly through associated pivoting-throughbores in the forehead engaging-stiffening member, and outwardly through associated pivoting-throughbores in the facing protecting-lens, and a pair of flat-head screws threadably engaging in the associated shafts of the studs from a direction of the facing protecting-lens and having heads disposed adjacent to the facing protecting-lens for setting friction level of the pivoting apparatus. The shafts of the studs have flats along a portion of their lengths extending from ends thereof so as to form flat portions having D-shaped lateral profiles. A pair of bushings being O-shaped and having D-shaped central throughbores fixedly receive the associated flat portions of the shafts of the studs and are disposed between and abut against the facing protecting-lens and the associated heads of the flat-head screws so as to prevent the studs from rotating and loosening each time the face protecting-lens is moved.
