| Abstract: |
A ventilated goggle having a face piece with a front wall, a top wall, a bottom wall, and side walls. The front wall is defined by a pair of laterally spaced wall sections that are substantially parallel to each other with each having an aligned aperture therein to allow the wearer to see therethrough. The open space between the laterally spaced wall sections form a channel that extends around the inner surface of the front wall and a plurality of spaced locking lugs are formed integrally with the outer walls of said face piece such that they project inwardly into said channel. The goggles have a single lens which is detachably positioned in said channel and the lens comprises a substantially planar central body shaped like the letter B laying on its side and has a plurality of spacers positioned at intervals around its periphery. The spacers are of a thickness greater than the thickness of the central body with that thickness extending laterally outwardly from both sides of the central body. The peripheral edge of the central body between the spacers is recessed inwardly from the peripheral edge of the spacers to form ventilation paths between the spacers when the lens is mounted in the channel.

What is claimed is:
1. A ventilated goggle comprising a face piece adapted to fit about the eyes of the wearer, said face piece having a front wall, a top wall, a bottom wall and side walls, said front wall being defined by a pair of laterally spaced wall sections that are substantially parallel to each other with each having aligned apertures to allow the wearer to see therethrough, the open space between said laterally spaced wall section forming channel that extends around the inner surface of said front wall, a plurality of spaced locking lugs being formed integrally with the outer walls of said face piece and extending inwardly into said channel, a single lens having its peripheral edge detachably positioned in said channel, said lens comprising:
- a substantially planar central body having a plurality of integrally molded spacers positioned at intervals around the periphery of the central body,
- said spacers being of a thickness greater than the thickness of said central body with said thickness extending laterally outwardly from both sides of said central body,
- the peripheral edge of said central body between said spacers being recessed inwardly from the peripheral edge of said spacers to form ventilation paths between said spacers when the lens is mounted in said channel.
