A hole for inserting a stay may be provided, and the mounting stay may be inserted into the hole and rotated so as to be in a retaining state at the retaining protrusion.
[0010]
2. Description of the Related Art A conventional swimming goggle eyecup connecting device has a structure in which a hole for fitting a convex portion of a nose belt is formed in a nose region of a peripheral wall of an eyecup itself. However, it is conceivable that a crack is generated from a hole formed in a nose portion region of the peripheral wall of the eye cup and a crack progresses with time, and there is a problem that durability is uneasy when used intensely. Was. Therefore, swimming goggles having an eye cup that is lightweight and excellent in durability are desired.
[0011]
However, when configured as described above, there is no hole in the nose part region of the peripheral wall of the eyecup itself, the occurrence of cracks in the eyecup is suppressed, and the eyecup is excellent in lightness and durability, and is particularly suitable for competition. . Further, the nose belt of the swimming goggles can be easily replaced and securely fixed. Further, the structure of a mold for molding the eyecup and the nose belt can be simplified.

[0012]
Conventionally, the size of the nose belt is generally 2.0 mm pitch for S, M, L and XL. The mountain-shaped nose belt with a stage adjusting function generally has an adjustment width of 5.0 mm pitch. On the other hand, the string-shaped nose belt can be adjusted steplessly. However, the string-shaped nose belt is very troublesome to adjust, and there is a problem that careful attention is required when tying the string to set a desired nose width. Therefore, it is desired that the nose belt be of a shape other than a string that is cumbersome to adjust.
[0013]
However, when configured as described above, the nose belt can be adjusted steplessly with the shape memory resin to improve the face wearability, and can be adjusted and stopped exactly, and water infiltration can be suitably prevented. In addition, the wearing feeling of the swimming goggles can be improved and the swimming goggles can be securely fixed.
{Circle around (6)} The nose belt may be heated to adjust the distance to a Shore D hardness of about 25 to 35, and cooled to be used at a Shore D hardness of about 70 to 80.
[0014]
With this configuration, the Shore D hardness is about 25 to 35 when the nose belt is heated and adjusted, so that the operability when bending by hand is excellent, and the Shore D hardness is about 70 to 80 when used. As a result, the nose belt is not easily deformed by the tension when the belt is worn on the head.
[0015]
In addition, the cushioning material for the face with respect to the eyecup may or may not be provided.
[0016]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0017]
As shown in FIGS. 1 to 6, the swimming goggles of this embodiment include an eyecup 1 for protecting eyes.
[0018]
The lens portion 3 of the eyecup 1 is inclined from the direction parallel to the face toward the traveling direction with the belt 2 attached to the head. The angle of the lens portion 3 of the eyecup 1 inclined from the direction parallel to the face toward the direction of travel as shown in FIGS. θ (eyepiece flange line) is preferably set in a range of about 5 to 15 °. The angle θ of the lens portion 3 of the eyecup 1 was set to about 10 ° in this embodiment.
[0019]
As shown in FIG. 5, a stay 5 for attaching a nose belt 4 (a hard elastomer material, hardness of 80 °) is protruded in a lateral direction in a nose part region of a peripheral wall of the eyecup 1, and a tip of the stay 5 for attaching The portion has a retaining projection 6 (bar). Further, the nose belt 4 has a hole 7 into which the mounting stay 5 having the retaining projection 6 is inserted. Then, the mounting stay 5 is inserted into the hole 7 in a horizontal direction, and is rotated by 90 ° so that the retaining protrusion 6 prevents the retaining stay.
[0020]
The nose belt 4 is formed of a shape memory resin, is heated with hot water or hot air of 65 ° C. or more, and is made flexible (Shore D hardness 25 to 35). When used, it is cured (fixed with a Shore D hardness of 70 to 80). This dimensional adjustment is a stepless adjustment. When the size is adjusted again by the user, the adjustment can be performed any number of times by repeating the operation.
[0021]
Next, the use state of the swimming goggles of this embodiment will be described.
[0022]
As shown in FIGS. 3, 4, and 6, in this swimming goggles, the lens portion 3 of the eyecup 1 is inclined from the direction parallel to the face toward the traveling direction when worn on the head. In a state in which the upper part of the face is facing upward in the forward direction in a prone or supine state like a form at the time of swimming, it is possible to secure a view from the lens unit 3 which is inclined from the parallel to the face in the forward direction, There is an advantage that it is possible to provide a swimming goggle that is less likely to generate distortion in the important traveling direction and has better visibility in the traveling direction than before.
[0023]
By the way, during swimming, the whole body is made as straight as possible in order to reduce the water flow resistance, and a posture with little resistance to the water flow is taken. The same is true for the head, and taking a posture that is as straight as possible with the body part has less water flow resistance. However, it is not always advisable to align the head unnecessarily in line with the buoyancy and form of the upper body, but this swimming goggle secures visibility in the traveling direction with little inclination of the head to the whole body. Is easy.
[0024]
When the angle θ of the lens portion 3 of the eyecup 1 inclined from the direction parallel to the face toward the traveling direction is set in the range of about 5 to 15 °, distortion between the front view and the upper eye direction is small, and the visibility is very low. When the angle θ is set to about 10 °, the distortion between the front view and the upper eye direction is smaller, the mutual balance is improved, and the visibility is extremely good.
[0025]
As shown in FIG. 5, a stay 5 for attaching a nose belt 4 is protruded from a nose portion region of a peripheral wall of the eyecup 1, and the stay 5 for attachment has a projecting portion 6 for retaining the nose belt. Reference numeral 4 denotes a hole 7 for inserting the mounting stay 5 having a retaining projection 6, and the mounting stay 5 is inserted into the hole 7 and rotated to prevent the retaining stay 6 from being removed by the retaining projection 6. As a result, the structures of the eyecup 1 and the nose belt 4 are simple, and the durability is excellent. Further, the nose belt 4 of the swimming goggles can be easily replaced and securely fixed. Further, the structure of a mold for molding the eyecup 1 and the nose belt 4 can be simplified.
[0026]
The nose belt 4 is formed of a shape memory resin, and is heated and made flexible so as to adjust the size according to the wearer's face, and is cooled and hardened at the time of use. The shape of the nose belt 4 can be adjusted steplessly by the shape memory resin to improve the wearing ability on the face, and it can be adjusted and stopped exactly by the shape memory resin. The infiltration of water can be suitably prevented, and the wearing feeling of the swimming goggles can be improved and fixed securely.
[0027]
In particular, in swimming goggles for swimming, a soft cushioning material (cushion material) is not attached in order to more securely fix the face, and a feeling of pressure on the face increases when the face is not along the face. It is of great significance that stepless adjustment is possible.
[0028]
【The invention's effect】
The present invention is configured as described above and has the following effects.
[0029]
Since distortion is less likely to occur in the field of view in the important traveling direction, it is possible to provide a swimming goggle that is more excellent in the field of view in the traveling direction than before.
