| 20110247119 | WELDING MASK - A welding mask includes a mask body formed with a viewing window, and an eye shield assembly including a window frame, a lens and a resilient positioning frame. The window frame is connected to the mask body, surrounds the viewing window, and includes an inwardly projecting stop and an opposing pair of inwardly projecting retaining portions disposed rearwardly of the stop. The lens is disposed removably between the stop and the retaining portions. The positioning frame is disposed removably between the lens and the retaining portions. The positioning frame defines a convex surface facing a direction away from the lens, and abuts against the retaining portions to thereby result in resilient deformation of the positioning frame and enable the positioning frame to press the lens against the stop. | 10-13-2011 |
