DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to swimming goggles.

[0002]

2. Description of the Related Art Conventionally, a side portion of a frame portion formed around a lens portion of a swimming goggle is extended toward a back of a wearer to form an upper and lower arm, and the arm supports a wearable band in an adjustable length. The technique for performing this is known or well-known. For example, Japanese Utility Model Application Laid-Open No. 64-20872 discloses that two parallel support arms are extended from each arm to the other arm so that the tips face each other, and the opposed tips are separated by a required distance. A disclosed structure is disclosed. By using such a structure, the wearing band can be easily guided from the gap between the tips to the band guide groove formed by the support arm, and the time required for assembling the swimming goggles can be reduced. The upper and lower side edges of the band that has been put in tension by wearing goggles are supported by contacting the support arms.

[0003]

In the above-mentioned prior art, when the distance between the ends of the opposed support arms is increased, the wearing band can be easily guided into the guide groove, but on the other hand, it tends to come off when tension is applied to the wearing band. It cannot be put to practical use. Therefore, even if the above-mentioned known technique is used, there is a problem that the shortening of the assembling time is somewhat sacrificed in practice, and the separation dimension must be reduced so that the worn band is not easily detached.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problem by providing means inside the buckle for fitting the upper and lower arms and the support arm so as to fill the gap between the tips of the support arms. I have.

[0005]

Means for solving the above problems The present invention is as follows to solve the above problems.

According to the present invention, there are provided a pair of left and right lens portions, a frame portion formed around the lens portions, a pad member made of a soft elastic material, and a wearing band. It is premised on a swimming goggle that supports the band so that its length can be adjusted between two upper and lower arms extending toward the back of the head.

[0007] Under such a premise, the two arms have a plurality of parallel support arms extending so that the tips face each other toward the other arm, and the two arms are opposed by the support arms. Two parallel U-shaped grooves are formed, and each of the opposed U-shaped grooves enables the band to be guided, and two parallel through holes through which the band to be guided can be inserted into the U-shaped groove. And a means capable of filling a gap between the tips of the support arms facing each other, and is characterized by having a buckle that can be fitted to the two arms from the front.

[0008]

In the swimming goggles constructed as described above, when the upper and lower arms are fitted with the buckle, the means provided inside the buckle fills the gap between the ends of the support arms facing each other. The arms bear against the support arms and means for filling the gap between them. Thereby, the problem that the wearing band is easily detached from the gap can be solved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the swimming goggles according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially exploded perspective view of the swimming goggles 1. The goggles 1 include a pair of left and right lens units 2.
And a frame portion 3 located around the lens portion 2, a pad member 4 detachable from a peripheral portion of the frame portion 3, and an outer portion 5 of the left and right frame portions 3 near the back of the wearer, which can be fitted from the front. Right and left buckles 6 and each buckle 6
The inner parts 8 of the left and right lens units 2 are connected via a well-known nose belt 9.

The lens portion 2 is made of transparent plastic, and a frame portion 3 is formed integrally with the lens portion. The outer portion 5 of the frame portion 3 is composed of upper and lower two arms 10, 11 separated by a dimension d extending in the direction of the back of the wearer, and each arm 10, 11 has a first arm extending in the thickness direction thereof.
There are U-shaped grooves 15A and 16A and second U-shaped grooves 15B and 16B.

The first U-shaped grooves 15A and 16A and the second U-shaped grooves 15B and 16B are located at positions facing each other and have the same width. These first and second U-shaped grooves 15A,
Side wall portion 10 participating in the definition of 16A, 15B, 16B
A, 11A, 10B, and 11B are referred to as first support arms 10A and 11A and second support arms 10B and 11B that support the wearing band 7 when tension is applied.

The buckle 6 is a member that can be detached by itself in the goggles 1 and its length can be adjusted by folding the free end of the wearing band 7 as shown. When the frame outer portion 5 is fitted with the buckle 6, the inner edge 18 of the buckle 6 comes into contact with the side edge of the pad member 4 (see the right eye portion in the figure).

The pad member 4 has a frame fitting groove 20 extending annularly at a front portion thereof, and has a pressure contact portion 21 to a wearer's face at a rear portion.

FIG. 2 is a perspective view of the structure of the frame outer portion 5 and the buckle 6 in the left eye portion of FIG. 1 when viewed from the wearer's face side, and the wearing band 7 is indicated by a virtual line. . The buckle 6 has first U-shaped grooves 15A and 16A and a second U-shaped groove.
First and second through holes 20, 21 for inserting the wearing band 7 having end portions corresponding to the contour shapes of the U-shaped grooves 15B, 16B.
And first, second, and third inner projections 22, 23, and 24, and peripheral ribs 25, 26. As shown, the first and second through holes 2
The wearing band 7 inserted and folded back through 0, 21 has a dimension d.
The space between the first U-shaped grooves 15A and 16A and the space between the second U-shaped grooves 15B and 16B. Next, when the buckle 6 is fitted to the frame outer portion 5 including the upper and lower arms 10 and 11 from the arrow Y direction, the upper and lower ends of the arm guide 30 on the side edge of the pad 4 and the outer peripheral edges of the arms 10 and 11 are provided. Fit inside the peripheral ribs 25 and 26 of the buckle 6. Incidentally, the upper and lower ends of the guide portion 30 are ribs 25 and 26, respectively.
It fits between each part 25A and 26A. In addition, each of the first, second, and third inner surface projections 22, 23, and 24 has a slightly smaller vertical dimension d than the first support arm 10A.
In the gap between the first and second projections 22 and 23, the gap between the first and second protrusions 22 and 23 is filled in the gap between the first and second protrusions 22 and 23. The right side edges of the first support arms 10A and 11A and the right side edges of the second support arms 10B and 11B are vertically aligned. The dimension of the gap 31 is d.

FIG. 3 is a plan view of the state in which the buckle 6 is fitted on the outer portion 5 when viewed from the face side, and the wearing band 7 is indicated by a virtual line. When the goggles 1 whose length has been adjusted by adjusting the turn-back dimensions of the buckle 6 are worn, the bands 7 forming two stripes in the vicinity of the outer portion 5 are all strongly pulled in the occipital direction indicated by the arrow X. Are supported by the first support arms 10A and 11A and the first protrusion 22 and the second support arms 10B and 11B and the second protrusion 23 in a vertical direction. If the first and second protrusions 22 and 23 are not provided here, the pulled band 7 will be connected to the first and second support arms 10A, 10B, 11A.
A, 11B escapes in the direction of arrow X from each gap,
It may not function as a wearing band. But,
Since this goggle 1 does not require such a worry,
By increasing the dimension d of the gap, the band 7 can be easily guided from the gap to the first U-shaped grooves 15A and 16A and the second U-shaped grooves 15B and 16B.

Referring again to FIG. 2, the frame outer portion 5
It has base ends 33 and 34 that are vertically divided by a gap dimension d,
Each of them extends from the inside of the fitting groove 20 (see FIG. 1) of the pad member 4 through the through holes 36 and 37 to the outside, and the through holes 36 and 37
Is in contact with the base portions 33 and 34 in a watertight state.
The base ends 33 and 34 may be continuous vertically without providing a gap d, and may extend outward from the fitting groove 20.
By doing so, the through holes 36 and 37 also become large continuous holes vertically connected, and slight deformation of the pad member 4 causes large distortion in the through holes, and as a result, a gap is formed between the base member and the base member. Can occur and impair the watertightness. However, in the goggles 1, since each of the through holes 36 and 37 can be relatively small, a good watertight state can be maintained.

[0018]

According to the goggles of the present invention, the wearing band is supported by the supporting arms extending from the upper and lower parallel arms and the buckle fitted on the supporting arms, and the buckle has a tip end gap between the opposing supporting arms. Since there is a means for filling, even if the gap is increased to facilitate attachment of the wearing band to the support arm, there is no fear that the band comes off from the gap when the goggles are worn.
