Patent attributes
A roll-off film system for goggles includes a goggle and a roll off system. The roll off system includes a first cap, a second cap, a bridge, a first canister, a second canister and a fixation system. The first and the second caps are fixedly connected by the bridge, and the first and the second canisters are fixed on the goggle through the fixation system. Both ends of a bottom of the first cap are respectively provided with a fixation rib. Thus, the roll-off film and shaft are fixed on the first and second caps to obtain a set of accessories. After the roll-off film is used up, the old first and second caps with the roll-off film are directly removed, and a new set of accessories are mounted. Users replace the roll-off film simply and efficiently. The whole set of accessories are easily assembled and disassembled.
