Swimming goggles
View Patent ↗Swimming goggles allow a swimmer to see the end of the pool without moving their head while swimming in backstroke. Using a light reflector, a swimmer can view through a backstroke viewing window to view along the backstroke moving direction. Swimmers wearing the goggles can therefore reduce the chance for injury while helping backstroke swimming efficiency.
1. A swimming goggle comprising:
an eye socket having a transparent forward viewing window attached to a goggle frame wherein the goggle frame further comprises a backstroke viewing window opened on a top portion of the goggle frame disposed away from the transparent forward viewing window; and
a position-switchable light blocking cover attached to an edge of the backstroke viewing window and is flippable with respect to the edge of the backstroke viewing window wherein the position-switchable light blocking cover is flipped to an open position to uncover the backstroke viewing window when a swimmer wearing the goggle is swimming in a backstroke orientation with the transparent forward viewing window facing an upward orientation, and the position-switchable light blocking cover is flipped to a close position to cover the backstroke viewing window when a swimmer wearing the goggle is swimming freestyle with the transparent forward viewing window facing a downward orientation.
2. The swimming goggle in claim 1 wherein:
the position-switchable light blocking cover is flipped to a close-position to cover the backstroke viewing window while the swimmer wearing the swimming goggle is swimming with the transparent forward viewing window facing sideward orientation.
3. The swimming goggle in claim 1 wherein:
the position-switchable light blocking cover is automatically flipped to an open-position to uncover the backstroke viewing window while the swimmer wearing the swimming goggle is swimming in the backstroke orientation.
4. The swimming goggle in claim 1 wherein:
the position-switchable light blocking cover is automatically flipped to an open-position by a gravity force acting on a weight attached to the position-switchable light blocking cover to uncover the backstroke viewing while the swimmer wearing the swimming goggle is swimming in the backstroke orientation.
5. The swimming goggle in claim 1 further comprises:
a light reflector to reflect the light coming through the backstroke viewing window into an eye of the swimmer wearing the swimming goggle while the swimmer is swimming in the backstroke orientation.
6. The swimming goggle in claim 5 wherein:
the light reflector comprises a half-mirror.
7. The swimming goggle in claim 5 wherein:
the light reflector is adjustable to change positions with respect to the back stroke viewing window depending on whether the swimmer wearing the swimming goggle is swimming in the backstroke orientation or not.
8. The swimming goggle in claim 5 wherein:
the light reflector is adjustable automatically to change positions with respect to the back stroke viewing window depending on whether the swimmer wearing the swimming goggle is swimming in the backstroke orientation or not.
9. The swimming goggle in claim 5 wherein:
the light reflector is adjustable automatically to change positions with respect to the back stroke viewing window by a gravity force acting on a weight that is attached to the light reflector depending on whether the swimmer wearing the swimming goggle is swimming in the backstroke orientation or not.
10. A swimming goggle comprising:
an eye socket having a transparent forward viewing window attached to a goggle frame; and
a position-switchable light reflector to switch to different positions with respect to the transparent forward viewing window depending on whether or not the swimmer wearing the goggle is swimming backstroke, wherein the position-switchable light reflector is flipped automatically to reflect an incident light coming from one end of a swimming pool into an eye of the swimmer wearing the goggle while the swimmer wearing the swimming goggle is swimming in the backstroke orientation with the transparent forward viewing window facing an upward orientation, and the position-switchable light reflector is flipped automatically to a position where an incident light coming from the end of a swimming pool does not reflect into an eye of the swimmer wearing the goggle when the swimmer is swimming freestyle with the transparent forward viewing window facing a downward orientation.
11. The swimming goggle of claim 10 wherein:
the position-switchable light reflector comprises a half-mirror.
12. The swimming goggle of claim 10 further comprising:
a backstroke viewing window opened on a top portion of the goggle frame disposed away from the transparent forward viewing window and is covered by a position-switchable light blocking cover attached to an edge of the backstroke viewing window and is flippable with respect to the edge of the backstroke viewing window; and
the position-switchable light blocking cover is flipped to an open position to uncover the backstroke viewing window and the position-switchable light reflector is adjustable to reflect the incident light coming from the backstroke viewing window into the eye of the swimmer wearing the swimming goggle when swimming in a backstroke orientation with the transparent forward viewing window facing an upward orientation.
13. The swimming goggle of claim 10 wherein:
the position-switchable light reflector is adjustable automatically to reflect the incident light coming from an end of a swimming pool into the eye of a swimmer wearing the swimming goggle when swimming in a backstroke orientation.
14. The swimming goggle of claim 10 wherein:
the position-switchable light reflector is adjustable automatically by a gravity force acting on a weight that is attached to the light reflector to reflect the incident light coming from an end of a swimming pool into the eye of a swimmer wearing the swimming goggle when swimming in a backstroke orientation.
