| Abstract: |
A spectacle frame mount provides secure, removable positioning of a spectacle frame in a gas mask or full face respirator. A spring wire mount supports the spectacle frame between two legs of a loop. The spring wire mount includes two leg portions that have lower ends which terminate adjacent each other when the mount is in its use position. The two leg portions positively engage an internal portion of the full face mask so that the spectacle frame will be positioned within the interior of the mask at a location such that the spectacles will be properly positioned for use by the person wearing the mask.
