摘要： A face shield assembly including a frame and a removable protective element supported by the frame is disclosed herein. The protective element is removably supported in an opening of the frame by a channel, without the use of fasteners. Because the face shield lacks fasteners, it is easy to remove and replace, even with the use of gloves. In one embodiment, the frame is molded as a single, unitary member and includes an upper detent, a lower detent and a channel formed between a lip and the frame that receives an edge of the protective element in order to hold the protective element within the frame. In another embodiment, the frame is pivotally supported on a support structure such that the frame can be moved between an upper (out of use) and a lower (in use) position, and may further include an adjustable mounting member so that the frame can be selectively spaced relative to the user's head.
