  • Patent number: 4856109
    Abstract: A transparent faceshield for protecting the face and eyes from impact and the like is detachably connected to an arcuate visor or crown using detents integrally molded to the crown and corresponding through-holes in the faceshield which receive and engage the detents. The use of integrally molded detents permits removable attachment of the faceshield to the crown without the necessity for secondary operations or discrete assembly hardware thus providing a system which is easily assembled and disassembled by the end user.

  • Patent number: 4711539
    Abstract: An optical lens carrying support structure for use with a protective face mask, comprising a pair of lens frames, each frame comprising an eyewire and a hinge portion, the lens frames being connected by a hinged nosepiece. The support structure attaches to the face mask by a slideably releasable dove-tail connection to a trapezoidal back-block, which back-block rigidly attaches to the face mask, with two opposite faces of the trapezoidal back-block inclined with respect to each other so as to establish the proper pantoscopic angle. The face-form angle is accomplished by virtue of an angled relation of the eyewire to the hinge portion of the lens frame. The lens frames fold back toward each other, facilitating removal of the lenses and folding the face mask assembly flat.
