DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to goggles used for swimming, skiing and the like.

[0002]

2. Description of the Related Art Conventionally, in such goggles, connecting opposing inner ends of a pair of left and right lens frames with a joint member is known as a conventional means.

[0003] For this joint member, a molded article of a flexible elastic material such as rubber or plastic elastomer is widely used.

[0004]

When the joint member is made of a soft elastic material, there are the following problems. One of the problems is that it is necessary to adjust the distance between the left and right lens frames to the left and right eyes of the wearer, which imposes a burden in various meanings. For example, goggle manufacturers sometimes have to supply various joint members of different lengths, while the wearer has to choose the optimal length from them and attach them to the goggles. These burden both the manufacturer and the wearer.

When the headband is tightened while wearing goggles, the outer end of the lens frame is pulled rearward, and the inner end moves in a direction in which the inner end rises (separates) from the face. Is getting weaker,
There is also a problem that water easily enters. And also
There is also a problem that the left and right lens frames are easily twisted around the joint member and take time when worn.

Therefore, an object of the present invention is to solve the above-mentioned problems in goggles.

[0007]

In order to solve the above-mentioned problems, the present invention is based on the premise that a pair of left and right lens frames provided with lenses and a pair of lens frames which are engaged with opposing inner ends of the frames. And a wearing band attached to the outer end of the frame.

[0008] On this assumption, it is a feature of the present invention that the joint member is made of a plastically deformable material.

[0009]

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

A swimming goggle 1 shown in a perspective view as an example of goggles in FIG. 1 includes a pair of left and right lens frames 4 in which a lens 2 and a frame 3 are integrally formed, and opposed inner end portions of the lens frames 4. 19 and the outer ends 20 of both lens frames 4
And a headband 6 extending therebetween.

A cushion pad 7 is attached to the outer peripheral edge of the lens frame 4. Lens frame 4
Is a molded product of a transparent hard plastic such as a polycarbonate resin or an acrylic resin.

FIG. 2 is a sectional view of the joint member 5 taken along the line II-II of FIG. 1. The member 5 in a flat state is a solid line, and the member 5 in a curved mounting state of FIG. 5 is indicated by a virtual line.

FIG. 3 is a sectional view taken along the line III-III of FIG.

The joint member 5 shown in FIGS.
Small pieces 21 of a stainless metal plate having a thickness of 0.3 to 0.7 mm
The upper and lower surfaces and the left and right sides are covered with a plastic elastomer 22 having a thickness of 0.5 to 2.0 mm,
A pair of first and second projections 23, which extend in the width direction of the
24 are formed. The first projection 23 is located near the edge 5A of the member 5, is slightly shorter than the second projection 24, and is inclined such that the top 23A becomes lower toward the edge 5A. A groove 26 extending in the width direction of the member 5 is formed between the first and second protrusions 23 and 24. A through hole 30 is formed in a required portion of the small metal plate piece 21, and the upper and lower elastomers 22 are connected to the through hole 30.

The joint member 5 having such a configuration is composed of
When both ends are pinched with a finger and bent like a virtual line, the small metal plate 21 is plastically deformed, and the elastomer 22 is deformed following the deformation. Even when the finger is released, the member 5 maintains its curved state. In addition, the member 5 can be returned to a flat state by plastically deforming the curved metal plate piece 21 again. The elastomer 22 is a metal plate piece 21.
Is connected to the outside of both side edges of the small piece 21 and the through hole 27, so that even if the small piece 21 is repeatedly deformed, the small piece 21 is not easily peeled off from the small piece 21.

FIG. 4 is an enlarged view of a main part in a cross section taken along line IV-IV in FIG. 1 and shows an engagement state between the joint member 5 and the lens frame 4. Inner end 19 of lens frame 4
, A joint member engaging hole 27 and an engaging protrusion 28 are formed. The shape and size of the engagement hole 27 are such that the first projection 23 of the joint member 5 can barely pass through,
The protrusion 24 is formed so as not to pass. Therefore, when one end of the joint member 5 is inserted into the engagement hole 27 from the outside of the lens frame 4, the groove 26 stops as fitted in the inner end 19 of the lens frame 4 as shown.
The inserted joint member 5 does not come off unless it is forcibly pulled out from the engagement hole 27. The engaging projection 28 abuts on the outer surface near the edge 5A of the inserted and curved joint member 5, and the edge 5A and the vicinity thereof are connected to the longitudinal center line CC of the goggle 1 (see FIG. 1). ), The bottom of the groove 26 is brought into close contact with the peripheral edge 27A of the engagement hole 27 near the center line CC. Due to the presence of the engagement projection 28, the joint member 5 does not easily come off even when the engagement hole 27 is relatively large.

In the present invention, the joint member 5 is
The entire metal plate piece 21 may be covered with plastic or rubber. This prevents the metal plate from directly hitting the skin, and at the same time prevents the plate from rusting. Instead of using the small pieces 21, the entire member 5 may be made of a plastically deformable plastic known as, for example, a plastic steel (trade name, manufactured by Aiwa Chemical Co., Ltd.).

[0018]

To adjust the distance between the left and right lens frames in the goggles configured as described above,
What is necessary is just to change the curved shape of the joint member. therefore,
It is not necessary for a goggle manufacturer to prepare various types of joint members, and for a wearer, the trouble of having to select an optimal joint member is eliminated. In addition, since the joint member of this goggle is made of a relatively high rigidity by using a small piece of metal plate or the like, the inner end portion of the lens frame can be easily viewed from the face even if the wearing band is strongly tightened when the goggle is worn. Never rise up. Furthermore, the left and right lens frames are not twisted at the joint member.
