Sport goggle with side vent for improved ventilation
View Patent ↗An improved sport goggle for skiing, motorcycling, paintball, racing, and other sports featuring clip-mounted side apertures communicating with the eye cavity of the goggle through adjacent venting apertures. Venting of the eye cavity of the sport goggle is aided by forming of the clip shape to create low pressure zones adjacent to the side venting apertures. The clips are rotationally attached to the goggle to provide an adjustable mount for the strap around heads or helmets while still forming the negative air pressure zone in all rotated positions. The clips may also be provided in a kit of differently dimensioned clips to adjust the negative air pressure venting characteristics of the clips and goggle to the intended sport or task.
1. A sport goggle for wearing on the face of a user having an improved air venting system to enhance air flow through the goggle, comprising:
a goggle body having an exterior surface and an interior surface and having a lens aperture surrounded by a top wall, a bottom wall, and two sidewalls;
a lens mounted in said lens aperture;
an eye cavity defined by the area between said interior surface, said lens, said top wall, said bottom wall, and said two sidewalls;
at least one side venting aperture communicating through one of said sidewalls of said goggle body with said eye cavity;
at least one clip, said clip having a leading edge and a trailing edge connected by a pair of side edges, an interior clip surface, and an exterior clip surface;
a clip aperture communicating through said clip between said interior surface and said exterior surface;
means of attachment of said clip to one of said two sidewalls;
said exterior surface of said clip between said clip aperture and said leading edge dimensioned to create a low air pressure area immediately adjacent to said clip aperture when moving air travels over said leading edge, whereby air flow exhausting from said eye cavity through side venting aperture is enhanced by the force of said low pressure area acting to draw higher pressure air from said eye cavity through said side venting aperture; and
wherein the means of attachment of said clip to said sidewall is a rotational engagement of said clip to said sidewall; and said rotational engagement engaging said clip to said sidewall at an attachment point wherein said trailing edge is translatable between a retracted position closest to said sidewall to an extended position, distanced from said sidewall, when said clip is rotated in said rotational engagement.
2. The sport goggle as defined in claim 1 wherein said attachment point is adjacent to said leading edge thereby maintaining said leading edge substantially adjacent to said sidewall when said trailing edge moves between said retracted position and said extended position.
3. The sport goggle as defined in claim 2 further comprising means for attachment of a strap to said trailing edge.
4. The sport goggle as defined in claim 2 wherein said rotational engagement of said clip to said sidewall comprises a hinged engagement of said clip to said sidewall.
5. The sport goggle as defined in claim 4 wherein said hinged engagement of said clip to said sidewall engages said interior surface of said clip to said sidewall thereby minimizing airflow interruption over said exterior surface of said clip.
6. The sport goggle as defined in claim 1 further comprising means for attachment of a strap to said trailing edge.
7. The sport goggle as defined in claim 1 wherein said rotational engagement of said clip to said sidewall comprises a hinged engagement of said clip to said sidewall.
8. The sport goggle as defined in claim 7 wherein said hinged engagement of said clip to said sidewall engages said interior surface of said clip to said sidewall thereby minimizing airflow interruption over said exterior surface of said clip.
9. A sport goggle for wearing on the face of a user having an improved air venting system to enhance air flow through the goggle, comprising:
a goggle body having an exterior surface and an interior surface and having a lens aperture surrounded by a top wall, a bottom wall, and two sidewalls;
a lens mounted in said lens aperture;
an eye cavity defined by the area between said interior surface, said lens, said top wall, said bottom wall, and said two sidewalls;
at least one intake aperture communicating through said lens or said goggle body with said eye cavity;
at least one side venting aperture communicating through one of said sidewalls of said goggle body with said eye cavity;
at least one clip, said clip having a leading edge and a trailing edge connected by a pair of side edges, an interior clip surface, and an exterior clip surface;
a clip aperture communicating through said clip between said interior surface and said exterior surface;
means of attachment of said clip to one of said two sidewalls;
said exterior surface of said clip between said clip aperture and said leading edge dimensioned to create a low air pressure area immediately adjacent to said clip aperture when moving air travels over said leading edge, whereby air flow exhausting from said eye cavity through said venting aperture is enhanced by the force of said low pressure area acting to draw higher pressure air from said eye cavity through said venting aperture;
wherein the means of attachment of said clip to said sidewall renders said clip removably engageable to said sidewall; and
means for attachment of a strap to said trailing edge.
