Head-worn optical protection device with lens clamp assembly

Abstract

A head-worn optical protection device includes a lens clamp assembly that facilitates adding and/or removing at least one of a plurality of lenses. The head-worn optical protection device may be a welding helmet particularly suited for laser welding applications. The lens clamp assembly includes one or more lens clamps that engage one or more lenses and holds the lens(es) against a lens frame in a main body of the protection device. In one embodiment, the lens clamp assembly may include a releasable lens clamp with an actuator that releasably engages the lens frame and facilitates removal of lenses in a lens stack. In another embodiment, the lens clamp assembly may include an outer lens clamp for securing an impact shielding lens in an outer portion of the lens frame and a separate inner lens clamp for securing optical lenses, such as DIN-rated lenses, in an inner portion of the lens frame.
