Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to goggles that protect the eyes from suspended dust, chemical spray, water drops, flying objects, wind pressure, and the like.

[0002]

2. Description of the Related Art Conventional goggles of this type are provided with a spectacle portion located in front of the eyes, a dustproof portion having flexibility surrounding the spectacle portion and attached to the spectacle portion, and a head portion for wearing the spectacle portion. It is often composed of a rubber band.

Further, the dustproof portion may be appropriately provided with a ventilation hole for preventing the inside of the eyeglass portion from becoming cloudy due to stuffiness or the like.

[0004]

However, in the above-mentioned goggles provided with the vent holes, when the goggles are used in rainy weather or in an environment where water or a chemical solution is handled, water drops may go into the goggles through the vent holes. Invasion or small suspended dust may pass through the ventilation holes and enter the inside.

The object of the present invention is to solve the above-mentioned problems,
The purpose is to provide goggles that are resistant to the entry of water droplets, dust, etc. while ensuring breathability.

[0006]

Means for Solving the Problems The goggles according to the present invention for achieving the above-mentioned object have a spectacle part made of a transparent hard material in front of the eye and a flexibility attached to the periphery of the spectacle part. The dustproof portion made of a material having, the eyeglass portion, and a mounting member for mounting the dustproof portion to the head, the ventilation hole formed of a large number of small holes in the dustproof portion, on these ventilation holes It is characterized in that a water-repellent ventilation cloth is attached in an isolated manner.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail based on the illustrated embodiments. FIG. 1 shows a perspective view of the goggles according to the present embodiment as seen from the front. A spectacle part 1 made of a transparent synthetic resin located in front of the wearer's eyes, and a spectacle part 1 which is joined to the periphery of the spectacle part 1 and which adheres to the face and is flexible in order to protect the eyes from dust, splashes, water drops and the like. And a pair of rubber bands 4 attached via a mounting portion 3 provided on the side surface of the dustproof portion 2 in order to attach the goggles to the head. In addition, a buckle 5 having a fitting portion for easily attaching and detaching the goggles is provided at the end of the rubber band 4.
The dustproof portion 2 is preferably made of a transparent material so that the surrounding area can be seen to some extent.

The spectacles section 1 is coated with, for example, a fog-preventing coating, and the upper and lower portions of the dust-proof section 2 are provided with a large number of through holes each having a side of, for example, 1.5 mm for venting air. The pores 6 are formed in a lattice shape. As shown in FIG. 2, these ventilation holes 6 are formed between the lattice-like bodies 2b in the region 2a of the dustproof portion 2 which is further lowered. Then, the mesh sheet 7 is attached to the frame portion, which is a high region 2c around the region 2a, so as to cover the ventilation hole 6 and separate from the ventilation hole 6 so as not to contact. The mesh sheet 7 is made of a breathable synthetic resin breathable cloth made of a water repellent material or a water repellent material.

As another embodiment of the vent hole 6 and the mesh sheet 7, the vent hole 6 is formed in the flat area 2c as shown in FIG. 3, and the mesh sheet 7 and the vent hole 6 are provided above the vent hole 6. It is attached so as to cover and bulge upward. As a result, the mesh sheet 7 can be isolated from the ventilation hole 6 so as to have a predetermined narrow space.

In any of the embodiments, the mesh sheet 7 has the ventilation holes 6 and the lattice-like body 2b having the ventilation holes 6 therebetween.
On the other hand, when the mesh sheet 7 is attached to the dustproof portion 2 so as not to come in contact with each other while having a narrow gap, that is, the mesh sheet 7 may be separated from the lattice-like body 2b and slightly inflated and attached to the region 2c. is necessary.

By doing so, it is possible to form a narrow space between the ventilation holes 6 or the grid-like body 2b and the mesh sheet 7 so as to isolate them from each other, and water droplets that have passed through the mesh sheet 7 form the grid-like body 2b. As a result of the inventor's study, it was found that the mesh sheets 7 can be retained by the surface tension and that the effect of reducing the penetration or circulation of water droplets into the ventilation holes 6 can be achieved.

Further, according to various experimental results by the inventor, even when the mesh sheet 7 having the same mesh is used, the size and the number of the ventilation holes 6 depend on the dustproofness of the goggles,
It was found that it has a great influence on the performance such as waterproofness and stuffiness.

If the mesh size of the mesh sheet 7 is selected against dust, it is easy to make the mesh sheet 7 have a sufficient dust-proof function, but the mesh sheet 7 is waterproof.
Has water repellency, but is not sufficient, and when water drops collect on the mesh sheet 7, they may pass through the mesh sheet 7. Therefore, if the size and the length of the vent hole 6 are appropriately selected, the water drop can be retained in the vent hole 6 by the surface tension and the penetration into the goggles can be made small.

In order to increase the surface tension of the ventilation holes 6, the diameter of the ventilation holes 6 may be reduced. However, if the air permeability is deteriorated, the number of ventilation holes 6 may be increased. The stuffiness can be improved. By separating the mesh sheet 7 from the ventilation holes 6 as described above, it is possible to prevent water droplets from directly flowing from the mesh sheet 7 to the ventilation holes 6. Further, compared to the case where the mesh sheet 7 is directly attached to the large hole portion as the ventilation hole due to the existence of the ventilation hole 6 having the small diameter, even if the mesh sheet 7 is hit by an object, the lattice-shaped body of the ventilation hole 6 having the small diameter is provided. 2b serves as a support member and also has a reinforcing function of preventing the mesh sheet 7 from being torn or damaged.

The goggles can be easily worn by the rubber band 4 regardless of whether or not the helmet is worn, and can sufficiently protect the wearer's eyes from wind pressure, dust, splashes and the like.

[0016]

As described above, the goggles according to the present invention can prevent the passage of fine dust, and even in an environment such as rainy weather, the water-repellent ventilation cloth repels splashes and water droplets cause ventilation cloth. Even if the water drops pass through, the water drops are blocked by the small-diameter vent holes, so that it is possible to prevent the water drops from flowing into the inside while ensuring air permeability.
