Description

  The present invention relates to swimming goggles that can easily confirm the direction of travel of a swimmer.

  When a person swims in a prone or lying position, the swimmer's line of sight is directed downward or upward and perpendicular to the direction of travel. Therefore, in order to confirm the situation in the traveling direction, it is necessary to wake up and turn in the traveling direction.

However, raising the face and directing it to the traveling method will forcibly change the swimming posture, so confirmation of the traveling direction tends to be neglected.
By the way, in a general pool, a plurality of swimmers often use the same lane at a certain distance, and in such a situation, the swimmer needs to check his / her direction of travel frequently. If you neglect, contact with others is inevitable.

  However, in the conventional swimming goggles, the direction of travel is checked directly through the lens of the swimming goggles. For example, in the case of crawl swimming, when the face is turned sideways by breathing, the face is moved in the direction of travel. It will be confirmed whether it contacts with other swimmers towards. If the face is turned in the direction of travel each time the direction of travel is confirmed, not only smooth swimming becomes difficult, but it also causes meandering. Further, if the confirmation of the traveling direction is neglected, there is a problem that the swimmer's hand contacts the other swimmer's feet in front or a part of the body of the swimmer swimming in the adjacent lane.

In order to solve the problem, Patent Document 1 discloses an invention in which a pedestal is provided in the lower side of the swimming goggles, a tilted mirror is attached to the pedestal, a traveling method is projected, and its safety is confirmed. .
According to the present invention, since the pedestal is provided, there is a problem that the lower part of the lens portion of the swimming goggles is covered thereby narrowing the field of view of the swimming goggles. Further, there is a problem that a member for providing the base is newly required.

Thereby, the swimmer wearing the swimming goggles can appropriately confirm that the forward swimmer is nearby without raising his face during swimming.

  Further, the angle θ can be determined by the size of the eye cup 11, for example, the distance and position between the lens portion 10 of the eye cup 11 and the swimmer's eye when the swimming goggles 1 are worn. Further, in the present embodiment, the angle θ is inclined upward, but may be inclined downward.

(Second Embodiment)
FIG. 4 is a schematic perspective view of a light beam reflecting portion provided in the lens portion according to the second embodiment of the present invention. The light reflecting portion 21 shown in FIG. 4 has a shape of a side face obtained by cutting a cylinder along the axial direction instead of a flat surface, and a central portion in the circumferential direction of the cylinder axis has a convex shape. FIG. 5 is a schematic view of the shape of the light beam reflecting portion 21.

Here, the light reflecting part 20 of the lens unit 10 of the first embodiment shown in FIG. 2 is a flat surface, and the width of the light reflecting part 20 in the front-rear direction is limited by the thickness of the lens part 10. Therefore, the width in the front-rear direction of the light reflecting portion 20 provided in the lens portion 10 is narrowed, and the front visual field is limited.
Therefore, the front field of view is enlarged by the function of the convex mirror by using the light beam reflecting portion 21 in which the central portion of the cylindrical side surface is convex as shown in FIG. As shown in FIG. 5, the cylindrical side surface of the light reflecting portion 21 may be formed with a radius r1. The radius r1 can be determined by the thickness of the lens unit 10 and the range of the visual field, but is preferably larger than the thickness of the lens unit 10. The light reflecting portion 21 is subjected to mirror processing.

FIG. 6 is a partial cross-sectional view of the lens unit 10 cut along the line II-II in FIG. 4. As shown in FIG. 6, the light beam reflecting portion 21 has a shape with a radius r <b> 1, but may be formed with an inclination of an angle θ from the rear side of the lens portion 10.
That is, in the cross section of the light reflecting portion 21, at a point A shown in FIG. 6, a straight line passing through the point A with the angle θ is a tangent to an arc with a radius r <b> 1. Thereby, the reflection of the light beam at the point A shown in FIG. 6 is not different from the case of the plane of the first embodiment, but the light beam in a wider range is incident at the point B than the point C which is a flat surface. The field of view is enlarged.

(Third embodiment)
FIG. 7 is a schematic perspective view of a light beam reflecting portion provided in a lens portion according to the third embodiment of the present invention. The light reflection part 22 shown in FIG. 7 is not a plane, but the center part of the lens part 10 in the left-right direction is concave. FIG. 8 is a schematic view of the shape of the light beam reflecting portion 22. The concave radius r2 is preferably larger than the radius when the shape of the lower edge of the lens unit 10 is approximated by an arc. Furthermore, as described in the second embodiment, an inclination of the angle θ may be provided. Further, the light reflecting portion 22 is subjected to a mirror surface treatment.
By setting it as such a shape, a swimmer's left-right direction can be expanded and seen.

(Fourth embodiment)
FIG. 9 is a schematic view of the shape of the light beam reflecting portion provided in the lens portion according to the fourth embodiment of the present invention.
9 is formed in the shape of radius r3, r4 in the left-right direction and the front-back direction of the lens part 10, respectively. The radius r3 and the radius r4 are preferably the same size as the radius r1 and the radius r2. The light reflecting portion 23 is also subjected to mirror surface processing.
Thereby, the field of view in the vertical direction in front of the swimmer is widened, and the field of view in the horizontal direction of the swimmer is expanded.

(Fifth embodiment)
FIG. 10 is a schematic perspective view of a swimming goggle in which a light reflecting portion is provided on the inner surface of an eyecup according to the fifth embodiment of the present invention.
10 is provided on the inner surface of the lower peripheral wall portion of the eye cup 11. The light reflecting portion 24 shown in FIG.
Since the light reflecting portion 24 is provided inside the lower peripheral wall portion of the eye cup 11, it is not necessary to provide a light reflecting portion inside the lens portion 10, and a mirror finish can be applied after the eye cup 11 is molded. Therefore, the light reflection part 24 can be easily provided.

  FIG. 11 is a cross-sectional view of the eye cup provided with the light beam reflecting portion 24, and is a schematic cross-sectional view taken along the line VV of FIG. Since the lower peripheral wall portion of the frame portion 12 has a shape extending annularly rearward from the outer peripheral edge of the lens portion 10, the light reflecting portion 24 has a concave shape at the center. Furthermore, it has an upwardly inclined shape. Although the lens unit 10 shown in FIG. 7 has substantially the same shape as that of the third embodiment in which the light reflecting part 22 is provided, the place where the light reflecting part is provided is different.

  In addition, although the light reflection part of each embodiment of this invention is made into the shape of the circular arc of radius r1-r4, the shape of a parabola may be sufficient instead of a circular arc. Moreover, the shape which can be approximated by an arc may be sufficient even if it is not a perfect arc.

  As described above, in the swimming goggles of the present invention, the light reflecting portion is provided on the inner surface of the lower peripheral wall portion of the lens portion 10 or the eye cup 11, and the swimmer uses the light reflecting portion to advance the face. The direction of travel can be visually recognized without turning to the side, and contact with other swimmers can be reduced.
