Abstract

PURPOSE:To provide the hydroscope which is light, has a comfortable feel to wear and is usable as sunglasses, etc., on land as well. CONSTITUTION:The peripheral edge of the rim of a spectacle front 1 is extended backward and on the other hand, a tubular packing 2 formed by sticking two resin moldings to each other is installed backward of the extending part of the rim. Fluid is sealed into the tubular packing 2. Since the tubular packing 2 is used in such a manner, this hydroscope has the higher ability to fit to the ruggedness of the face than the conventional hydroscopes and can effectively proofs water even if the hydroscope is not pressed to the face with so much high force. The face contact pressure is averaged by the flow of the fluid in the packing 2 and, therefore, the hydroscope is painless.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing dual-use spectacles.

[0002]

[Prior Art] Even today, when marine sports are at their peak,
There are no fashionable underwater glasses. Current underwater eyeglasses are generally large and rugged, and, moreover, the band tightly tightens the head to make it difficult. Appearance and comfort are sacrificed in order to enhance the waterproofing properties of the underwater glasses. Therefore, there are very few people who regularly wear water glasses on land.

However, since it is easy for the retina to be damaged by ultraviolet rays in a sunny summer sports day, it is not desirable to stay naked on land. Therefore, it was very annoying because it was necessary to change the pair of underwater glasses when going into the sea and sunglasses when going up to the land.

[0004]

Therefore, according to the present invention,
It is a technical issue to provide eyeglasses that are waterproof and yet have excellent appearance and comfort and can be used both underwater and underwater.

[0005]

In the present invention, the rim peripheral portion of the spectacle front is extended rearward in a skirt shape, while the gutter portion is bent in substantially the same shape as the rear portion of the extended rim peripheral edge. Mold two resin moldings that you have, overlap the two moldings so that the concave surfaces of the gutter face each other, and seal the fluid inside while crimping the surroundings except the concave surface of the gutter. The problem was solved by adopting a means of forming a tubular packing that is bent in substantially the same shape as the rear portion of the peripheral edge of the extending rim and then attaching the tubular packing to the rear of the peripheral edge of the extending rim. ..

EXAMPLES The present invention will be described below based on examples.

First, the front 1 of the spectacles is integrally molded with a hard resin. At this time, the peripheral edge of the rim of the front 1 is extended rearward, and is further extended toward the left and right ends. In addition, one groove is located at the rearmost end of the rim peripheral extension.
Drill 11

Next, an annular molded body 21/22 is formed of a soft resin, which has a trough portion having substantially the same shape as the rear portion of the rim extending portion, and both edges of the trough portion are formed so as to project like flanges. .. In addition, one of the two molded bodies 21 and 22 has a ridge-shaped top portion connected to the back side of the trough portion, that is, the side protruding in the ridge shape.
Set up the ridge of the article. In this way, the two annular molded bodies 21
・ If 22 is obtained, the two molded bodies 21 and 22 are overlapped on the open side of the gutter, and air is enclosed in the tubular sealed space formed by the overlap of the gutters at atmospheric pressure, while forming a flange shape. Both edges are heat-sealed. After that, the flange-like edge is cut off while leaving the circumference of the tubular portion slightly, so that the tubular packing 2 having one projecting ridge can be obtained.

The tubular packing 2 obtained as described above is attached to the rear of the rim peripheral extension of the spectacle front 1 integrally molded with the hard resin. At this time, the tubular packing 2
And the groove formed behind the rim peripheral extension
11 shall be attached so that they fit together. After this,
By attaching the lens 3, the temple 4 and the like to the spectacle front 1 and further connecting the band 5 to the temple 4, the spectacles for both land and land are manufactured.

[0010]

As described above, when the above-mentioned amphibious spectacles are actually put on the face and used, the tubular packing closely follows the irregularities of the face, and at the same time, the concave portions and the convex portions are caused by the fluid flow inside. Also, since the contact pressure is averaged and it comes into contact with the face, it is possible to completely waterproof the water glasses without hitting the face with a very strong force, and it is comfortable to wear. Moreover, since the fluid flows inside, the packing can sufficiently follow even large irregularities, so that it can be made smaller than conventional products, and the degree of freedom in design is increased. Therefore, the spectacles can be used not only underwater but also on land and can be used both for land and water. As described above, the manufacturing method of the present invention enables the manufacture of the spectacles for both land and land, which have never been seen before, and has a high industrial utility value.

Claims (1)

[Claims] 1. A rim peripheral portion of a spectacle front is extended rearward in a skirt shape, and two resin molded bodies having a trough portion bent in substantially the same shape as a rear portion of the extended rim peripheral edge are molded. , The two molded bodies are overlapped so that the concave surfaces of the gutters face each other, and the fluid is enclosed inside while the edges of the gutters are crimped to each other, and then the tube is bent into a shape substantially the same as the rear part of the peripheral edge of the extending rim. After the packing is constructed, the tubular packing is attached to the rear side of the peripheral edge of the extending rim, and the method for manufacturing the amphibious / spectacles.
