Description

  The present invention relates to sunglasses having a light shielding property so that sunlight does not enter the eyes obliquely when playing golf or the like.

  It is common to wear sunglasses to protect your eyes from strong sun rays. For example, when driving a car, marine sports are often used at sea. In addition, baseball players often wear so as not to interfere with catching the ball due to the sun's glare when defending a day game at an outdoor stadium. Thus, sunglasses are protective glasses worn to prevent sunlight, and can reduce glare and ultraviolet rays.

  However, even when wearing sunglasses, sunlight may enter through the gap between the front part of the sunglasses and the face. Especially for professional athletes, the incident of light from the gap has a significant effect on the outcome. To do. For example, when playing golf, the golf ball is looked at obliquely and the club is raised and struck, but there is a concern that the light reflected on the ground may enter from the obliquely lower side and get out of hand.

  On the other hand, there are many people who wear sun visors to block the sunlight that shines from diagonally above. However, depending on the position of the sun, it cannot always be blocked by the sun visor. Many people also hate wearing sun visors. Therefore, there are also known glasses equipped with sun visors that block sunlight.

The “sunglasses visor” according to Japanese Patent Application Laid-Open No. 2007-52180 is a glasses visor that covers the minimum light-shielding range as a sunvisor, does not deteriorate the visibility of the user, and does not narrow the field of view. .
That is, the spectacles sun visor is configured to have a light shielding plate that covers a part of the upper side of both lenses at the front portion of the glasses, and a support material that attaches the light shielding plate to the front portion of the glasses or both lenses. Therefore, the light shielding plate only covers a part of both lenses. As a result, the sunshade function can be fully exerted, and at the same time, a sufficient bright field can be secured in the left, right, top and bottom, so that convenience in driving a car is extremely high.

However, attaching a light-shielding plate to the front part of the glasses is heavy and disturbing for athletes who exercise. In addition, it is difficult for the light shielding plate to block sunlight rays reflected from the ground and entering obliquely from below, and is not suitable for at least golf players.
"Sun visor for glasses" according to Japanese Patent Application Laid-Open No. 2007-52180

  As described above, the conventional sunglasses and the sun visor for glasses have the above-described problems. The problem to be solved by the present invention is this problem, so that even if worn by athletes, there is no sense of incongruity, and so that the sun rays shine through the gap with the face and do not enter the eyes. And a nose pad that can be attached to the center of the front part of the sunglasses.

  The nose pad that has light-shielding properties according to the present invention prevents sunlight from entering through the gap between the front portion and the face when wearing sunglasses, so that it cannot be seen. Therefore, the shape of the nose pad includes a light-shielding plate that is connected at the upper part of both pad parts that hit both sides of the nose and that extends upward from the upper part. Here, the means for attaching the nose pad to the center of the front portion is not particularly limited, and a connecting piece may be formed on the light shielding plate and screwed, or may be integrally formed with the front portion.

  And the front part of the sunglasses of the present invention is greatly curved so as to adapt to the face, and the gap formed between the face and the face is reduced. The basic form of the sunglasses is the same as the conventional one, and a vine is attached to both side ends of the front part via a joint so that the vine smoothly curves and extends so as to fit the side of the face. The material of the vine may be made of metal or resin.

  The sunglasses according to the present invention can naturally reduce the glare of sunlight from the front, ultraviolet rays, etc., and can also block the light reflected off the ground and entering from obliquely below. That is, the front portion has a shape that is greatly curved so as to be adapted to the face, and a gap between the front portion and the face is made small, and the incident of light can be suppressed from this gap.

  On the other hand, it is not easy to reduce the gap between the front part of the smoothly curved shape and the face at the center part, but in the present invention, the sun enters the eyes by shining from below with a nose pad. Can block the rays. That is, the two pad parts of the nose pad are connected at the upper part to form an approximate mountain shape, so that light does not enter from the upper spaces of the two pad parts that are separated as in the prior art. And since the shielding board extended upwards stands at the upper part of a nose pad, this shielding board also prevents the light which injects from entering into an obstruction.

It is an Example which shows the sunglasses which concern on this invention, and represents the top view and the front view. It is an Example which shows the sunglasses which concern on this invention, and represents the side view. The specific example which shows the nose pad according to the present invention. Schematic wearing conventional sunglasses. Schematic wearing sunglasses of the present invention.

  1 and 2 show an embodiment of the sunglasses according to the present invention. FIG. 1 shows a plan view and a front view, and FIG. 2 shows a side view. In the figure, 1 is a front part, 2 is a crane, 3 is a nose pad. The front portion 1 is configured by two lenses 4 and 4 being screwed between a connecting piece provided on the nose pad 3 and a front member 20 horizontally disposed on the front side. Then, the end pieces 5 and 5 are screwed to both ends of the front portion 1, and the above-described temples 2 and 2 are attached to the end pieces 5 and 5 via joints 6 and 6.

  By the way, as shown in the figure, the front portion 1 has a greatly curved shape, and when compared to conventional sunglasses, the gap between the face and the face can be suppressed as much as possible when worn on the face. I can do it. In the front portion 1 in the figure, the crossing angle θ between the straight line connecting the center and the joint 6 and the base line 16 is 19.6 °. Of course, in the present invention, the specific size of the crossing angle θ is not limited, but generally 18 ° to 21 ° is suitable.

  The front part 1 has two lenses 4, 4 arranged symmetrically and is connected to the nose pad 3 by the front member 20, but is connected to the nose pad 3 shown in FIG. The connecting pieces 11, 11 are used. The nose pad 3 has two pad portions 9 and 9 that are in contact with both sides of the nose and are connected to each other at an upper portion thereof to form a generally chevron. Of course, the pad portions 9 and 9 form a smooth curved surface so as to fit on both sides of the nose, and a soft silicon layer can be formed on the contact surface as the inner surface if necessary.

  A light shielding plate 10 extends upward from above, and the connecting pieces 11 are extended outward on both sides of the light shielding plate 10. And the small hole for a screw to penetrate penetrates in the front-end | tip of the connection pieces 11 and 11. Screws are inserted through the small holes, and the lenses 4 and 4 are sandwiched between the front member 20 disposed on the front side and screwed. The shading plate 10 has a certain thickness, and the inner (back side) upper part forms a smooth arc so that it does not hit the forehead of the face when wearing sunglasses. However, the shape of both the pad portions 9 and 9 and the shape of the light shielding plate 10 are not limited to the case of FIG.

  Thus, the lenses 4 and 4 are connected symmetrically with the nose pad 3 in between, but the tips of the connecting pieces 11 and 11 and the lenses 4 and 4 are screwed. In this case, the front surface of the connecting pieces 11, 11 and the front surface with the edge of the light shielding plate 10 fitted between the lenses 4, 4 so that the lens 4 can be stably fixed without rotating with a single screw. It is fixed without rattling by being pinched by the member 20 and screwed.

  Then, as shown in FIG. 1, a crane 2 is connected to both side ends of the smoothly curved front portion 1 via a joint 6, and the joint 6 is connected to a joint piece 7 formed at the tip of the armor 5 and a crane. The joint piece 8 formed at the end of 2 is combined with each other. However, the joint structure is not limited, and it is free to use a hinge joint that has been widely used in the past.

As shown in FIG. 2, the crane 2 is connected at the tip, but has two wires 12, 12 extending at a predetermined interval, and the front-side tip of the wires 12, 12 is a joint piece 8. The joint piece 8 meshes with the joint piece 7 of the alloy 5 and is connected by a screw pin 14. Moreover, the modern part 13 which is the front-end | tip part of the vine 2 is not straight, but is waved and extended in the uneven | corrugated shape.

  FIG. 4 shows a light shining state when playing golf while wearing conventional sunglasses, and FIG. 5 shows a comparison of light shining states when playing golf while wearing sunglasses of the present invention. . In the figure, reference numeral 15 denotes a golf ball located on the ground. Therefore, when the golf ball 15 is viewed from the front, there is no problem even with conventional sunglasses. That is, sunlight does not enter the eyes directly.

  However, when the golf ball 15 is hit with a golf club as shown in (b), the face is inclined with respect to the golf ball 15, so that the sun reflected from the gap between the wearing sunglasses 17 hits the ground. Rays shine into the eyes. As a result, the golf ball 15 cannot be hit accurately, and the golf ball falls into a bunker or forest. If you are wearing general corrective glasses instead of sunglasses, you will not be bothered by the light that shines through the gap, but if you are wearing sunglasses, you will not notice the slight light from the gap. Will greatly affect play.

  Of course, the same problem occurs whether the golf club used is a driver or an iron. FIG. 4B shows a case where conventional sunglasses are worn. A gap 18 is formed between the front portion 1 and the face 19, and sunlight reflected from the gap 18 is incident on the ground. Get into the eyes. The front part 1 of the conventional sunglasses is relatively flat, and the gap 18 formed between the face 19 is large.

On the other hand, in the case of the sunglasses 17 according to the present invention, the front portion 1 is greatly curved in conformity with the face 19, and therefore the gap 18 with the face 19 is small.
And in the sunglasses of this invention, the nose pad 3 is attached to the center part of the front part 1. FIG. The nose pad 3 has a generally chevron shape with the upper portions of both pad portions 9 and 9 connected. And since the light-shielding plate 10 extended upwards from the upper part of the pad parts 9 and 9 is provided, the sunlight ray reflected on the ground by this nose pad 3 is interrupted. In other words, the sun rays entering from the gap 18 at the center of the front portion 1 do not pass through the nose pad 3 and enter the right eye 21a.

  Of course, this sunglasses is configured so that the sun rays reflected mainly on the ground are not directly seen by the eyes, but it is also possible to block the sun rays entering obliquely from above. In other words, the shielding plate 10 erected upward from the upper portions of the pad portions 9, 9 of the nose pad can also block light that is directly incident from the sun positioned obliquely upward when the golf ball 15 is hit.

  In this way, when playing golf while wearing the sunglasses 17 according to the present invention, the golf ball can be hit accurately without being concerned about the sun and being disturbed by the sun rays. Of course, the sunglasses 17 of the present invention are not intended only for golf, and can be worn freely when playing baseball or skiing, and the effect is great.
