Description

[Background of the invention]
The present invention relates to sunglasses. More particularly, the present invention relates to sunglasses worn by motorcycle, bicycle, and other vehicle riders who experience strong wind blowing on their faces.

  Some spectacles currently available have various types of additional protection around the outer periphery of the spectacles that reduce the wind blowing on the face of the rider. Unfortunately, this extra protection of the glasses reduces the amount of air circulation on the inner surface of the back of the glasses near the face. When air circulation is reduced, moisture can accumulate and condensation and fogging occur on the inner surface of the back of the glasses. Condensation and cloudiness reduce the visibility of the rider. Bicycles and motorcycles can move at relatively high speeds, and sufficient visibility is a major safety concern.

  Equipment such as ski goggles is designed to reduce the effects of wind hitting the eyes and minimize the accumulation of condensation. Ski goggles are often manufactured with inner and outer lenses that form a generally enclosed chamber. The air in the room is warmed by approaching the face. The higher temperature of the room air relative to the outside ambient temperature helps to reduce the accumulation of condensation. Unfortunately, ski goggles are very large for the rider of a motorcycle. Furthermore, ski goggles are not an aesthetically appealing design for bicycle and motorcycle riders.

  Accordingly, there is a need for sunglasses that have additional protection around the edges of the glasses to reduce the wind blowing on the face of the rider. In addition, the glasses should also have a source to reduce condensation and haze on the inner surface behind the glasses. Glasses must be lightweight and comfortable for the rider, while creating an attractive aesthetic image.

[Summary of Invention]
It is an object of the present invention to reduce the airflow that strikes the eyes of a rider. Motorcycles, bicycles, and other vehicles can move at high speeds, creating a significant air flow around the glasses and toward the eyes. The strong air flow around the periphery of the glasses can severely moisten the eyes, and this moistening of eyes reduces visibility and affects safety. The advantage of a liner pad is that it reduces the airflow that strikes the eyes, thereby increasing the vision and comfort of the rider.

  Another object is to provide sufficient airflow through the glasses to prevent the accumulation of condensation on the inner surface of the glasses frame. In order to reduce the accumulation of condensation, reducing the wind from around the outer periphery of the glasses in contact with the inner surface must be compensated in some way. Motorcycle and bicycle travel can be an intense activity. Sweat often accumulates on the face of the rider, and the sweat evaporates and accumulates on the glasses as condensation. A hole is provided that allows the air flow to the inner surface to be reduced. The advantage of the hole is a reduction in the accumulation of condensation, which increases visibility and safety.

  Another object is easy installation and removal of the protective liner pad from the spectacle frame. It is an important advantage to easily switch from just ordinary glasses to ventilated glasses mechanisms with pads. Removing the inner frame and liner pad reduces the weight of the glasses and thus increases comfort. Some wearers also believe that glasses with the inner frame and pad removed are more aesthetically appealing. By providing the detent, the inner frame having the protective pad is quickly reattached to the glasses when starting to move with the motorcycle. Detents are beneficial because they save time and reduce frustration, and provide a method for quick installation and removal of the inner frame from the spectacle frame.

  The ventilated eyeglass mechanism has a pad that serves as a liner for the inner frame. The pad reduces the air flowing from around the peripheral edge of the glasses to the eye. A cavity with a partial seal of air is formed by the wearer's face and a ventilated spectacle mechanism with a pad. The partial seal of air prevents a significant amount of air flow around the peripheral edge of the spectacle frame. The absence of air flow results in the accumulation of moisture and condensation within the cavity. If there is not enough ventilation, condensation will accumulate on the inner surfaces of the left and right lenses, making the field of view unclear.

  Condensation is reduced by adding holes to the eyeglass frame device that form small holes to increase the air flow. The holes are small enough to minimize the strength and velocity of the air flow, but are also large enough to allow a certain amount of air to flow away from the inner surface.

  One embodiment of a ventilated eyeglass system having a removable pad and detent comprises an eyeglass frame having an outer surface and an inner surface. The spectacle frame has a left temple, a right temple, and a nose bridge support. The first hole and the second hole are located in the nasal bridge support portion, where condensation is most likely to occur. Air can flow from the outer surface to the inner surface through the first hole and the second hole.

  The left lens and the right lens are attached to the spectacle frame. The left lens and the right lens form part of the inner surface. The air flowing through the first hole and the second hole removes condensation from the inner surface and dries the left lens and the right lens.

  The inner frame is attached to a spectacle frame having a detent. The detent includes a male part and a female part that receives the male part. The detent securely fixes the inner frame to the spectacle frame. The inner frame has a pad that significantly reduces wind blowing on the wearer's eyes. The pad is positioned on the back surface of the inner frame and can be pressed against the wearer's face. The pad has a thickness “t” of about ¼ (0.25) inches.

  The inner frame includes a first track and a second track. The spectacle frame has an associated first ridge and second ridge. The first track leads the first ridge and the second track leads the second ridge. The inner frame is guided to an appropriate alignment state so that it can be attached to the spectacle frame.

  The spectacle frame has a third hole and a fourth hole that are similar in function to the first hole and the second hole. As air flows through the third hole and the fourth hole, condensation can be removed from the inner surface. The third hole is located near the right temple, and the fourth hole is located near the left temple.

  Although the invention has been briefly outlined, a more complete understanding of the invention can be obtained from the following drawings, detailed description, and appended claims.

  These and other features, aspects and advantages of the present invention will be better understood with reference to the accompanying drawings.

[Detailed Description of Preferred Embodiments]
With reference to FIGS. 1-6, particularly FIGS. 1 and 6, a ventilated spectacle mechanism 10 having a removable pad 12 and a detent 14 includes a spectacle frame 16 having an outer surface 18 and an inner surface 20. The spectacle frame 16 includes a left temple 22, a right temple 24, and a nose bridge support portion 26. The first hole 28 and the second hole 30 are located in the nasal bridge support portion 26, where condensation is most likely to occur.

The other detent 14 ′ is located on the right side 44 of the nasal bridge support 26. The female portions 40, 40 ′ are located on the nasal bridge support portion 26. The male portions 38 and 38 ′ are located on the inner frame 36. The detent 14 is located near the first hole 28, and the detent 14 ′ is located near the second hole 30.

  With reference to FIGS. 3, 4, and 6, the inner frame 36 has a pad 12 that significantly reduces wind blowing on the wearer's eyes while wearing glasses. The pad 12 is positioned on the back surface 46 of the inner frame 36 so that it can be in close contact with the face of the wearer. The pad 12 is a foam or other flexible material that is gentle and comfortable to the wearer's skin. The foam can fit the shape of the wearer's face due to its flexibility.

  As shown in FIG. 6, pad 12 has a thickness “t” between about 1/16 inch and about ½ inch. In the preferred embodiment, pad 12 has a thickness “t” of about ¼ (0.25) inches. The first hole 28 and the second hole 30 work best when combined with the pad 12. The pad 12 minimizes the airflow that hits the eye from the periphery 48 of the ventilated eyeglass mechanism 10. The first hole 28 and the second hole 30 can reduce the speed of the air flow circulating through the inner surface 20 to some extent. The reduced airflow is more gentle to the eye and minimizes or eliminates the accumulation of condensation.

  With reference to FIGS. 1, 2, 4, and 5, the inner frame 36 includes a first track 50 and a second track 52. The spectacle frame 16 has a corresponding first ridge 54 and second ridge 56. FIG. 2 is an enlarged view of the first track 50 and the first ridge 54. The first track 50 receives the first ridge 54 and the second track 52 receives the second ridge 56. Accordingly, when the inner frame 36 is attached to the spectacle frame 16, it is guided to an appropriate alignment state. A secure connection is provided between the inner frame 36 and the spectacle frame 16 along with the detents 14, 14 ′. The first ridge 54 and the second ridge 56 are on the inner surface 20. The first ridge 54 is indicated by a dotted line because it is hidden in the rear perspective view of FIG.

  With specific reference to FIGS. 2 and 4, the first track 50 has a first recess 66 that receives a hinge projection 70. The hinge protrusion 70 is attached to the first ridge 54. Similarly, the second track 52 has a second recess 68 that receives the hinge projection 70. A screw 72 passes through the middle of the hinge protrusion 70.

  Referring to FIGS. 1, 5, and 6, the spectacle frame 16 is provided with a third hole 58 and a fourth hole 60 that are similar in function to the first hole 28 and the second hole 30. ing. As the air flows through the third hole 58 and the fourth hole 60, dew condensation can be removed from the inner surface 20. The third hole 58 is located near the left temple 22, and the fourth hole 60 is located near the right temple 24.

  The spectacle frame 16 also has a fifth hole 62 and a sixth hole 64 that provide additional air flow from the outer surface 18 to the inner surface 20. These holes are small in size to reduce the strength and speed of the air flow. By providing several holes, sufficient airflow is maintained at the dropped speed and condensation is removed from the inner surface 20. Since condensation does not accumulate on the inner surface 20, visibility is maintained. The nasal bridge support portion 26 is divided into a left side portion 42 and a right side portion 44. The first hole 28 and the fifth hole 62 are located on the left side portion 42 of the nasal bridge support portion 26. The second hole 30 and the sixth hole 64 are located on the right side 44. The first hole 28 and the fifth hole mainly remove condensation from the left lens 32, and the second hole 30 and the sixth hole 64 mainly remove condensation from the right lens 34.

  The left lens 32 and the right lens 34 are colored to protect the eyes from the sun. Although not shown, the ventilating spectacle mechanism can include an interchangeable lens. The left lens 32 or the right lens 34 can be removed from the spectacle frame 16, and the interchangeable lenses 32, 34 can be snapped into place.

  The ventilated eyeglass mechanism 10 has several advantages. The strong air flow around the perimeter 48 of the ventilated spectacle mechanism 10 is greatly reduced by the pad 12. As eye irritation is reduced, visibility is increased and safety is increased. The addition of the holes 28 and 30 generates a sufficient air flow so that condensation on the inner surface 20 of the spectacle frame 16 is reduced. The detents 14, 14 ′ facilitate attachment and removal of the protective liner pad 12 from the spectacle frame 16. Removing the inner frame 36 and the liner pad 12 when not desired substantially reduces the weight of the glasses, thereby increasing comfort for the wearer. The first track 50 is guided by the first ridge 54 so that the inner frame 36 is guided to a correct alignment state with the spectacle frame 16.
