| Abstract: |
Disclosed is a shield for protecting the eyes and at least the upper half or more of the face of the wearer and comprises a head-encircling element having a frontal part of relatively rigid material provided with oppositely extending wings for receiving pockets on a headband. The frontal part is configured to conform to the brow of the wearer and a compatibly configured frame is mounted on the frontal part by a transverse hinge. A protective screen of transparent nature depends from the frame in a protective mode and, because of the hinge, can be swung forwardly and upwardly away from and downwardly and rearwardly back to the protective mode. The screen may be removed from the frame and the headband from the frontal part for laundering, sterilizing, etc.

I claim:
1. A face shield, comprising a head-encircling element including a frontal part adapted to fit against the brow of the wearer and having a relatively rigid central support portion, a protective screen positionable in a protective mode in dependent relation to the frontal part and closely ahead of the eyes of the wearer, said screen having an upper edge portion closely proximate to the support portion of the frontal part, and screen-mounting means including a relatively rigid frame disposed closely ahead of the frontal part and of U-shaped configuration as seen from above so as to generally conform to the brow of the wearer, said screen-mounting means further including a hinge on a transverse axis connecting a central region and the frame and the central support portion of the frontal part, the screen being also U-shaped to conform to the frame and the upper edge portion of the screen being removably carried by the frame and said frame further including a downwardly-opening channel configured to conform to the frame and relatively tightly receiving the upper edge portion of the screen, and said shield being initially flat and of flexible material adapted to be manually curved to fit the channel and capable of returning to its flat status when removed from the channel.
