BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a respirator, and more particularly to a full-face mask incorporating glasses.

[0002]

2. Description of the Related Art With a conventional full-face mask, when a spectacle wearer wears the full-face mask, it is not possible to wear the full-face mask while wearing ordinary glasses. In other words, since the vine of the glasses impairs the airtightness of the mask and causes leakage, the glasses are removed and the entire mask is mounted. Then, the field of vision is blurred, and the object becomes invisible, so that the work efficiency is reduced and a safety problem is caused.

Therefore, various means and methods for incorporating glasses inside the entire mask have been devised.

However, in use, it takes time to adjust the position of the lens or the positional relationship between the lens and the eyeball. In addition, since the eyeglasses come into contact with the bridge of the nose, it takes a long time. With the passage of time, a feeling of pressure is concentrated on a part of the bridge of the nose, which makes it difficult to wear the nose for a long time.

The present invention has been made in view of such a problem, and it is possible to securely fix an eyeglass in an optimal state at the same time as wearing a mask, without performing fine adjustment of the eyeglasses. An object of the present invention is to provide a full-face mask and dedicated glasses that can be worn for a long time while preventing a feeling of pressure from concentrating on a part of the nose bridge.

[0006]

According to the present invention, there is provided an overall mask,
A support pin upper mounting protrusion and a support pin lower mounting protrusion for mounting the support pins of the mask exclusively for the mask are provided at both ends of the eye glass inside the mask body.

Further, the glasses for exclusive use of a full-face mask of the present invention include a frame in which a lens is fitted, hooks integrally provided on both right and left ends of the frame, an elastic support band connected to the hooks, and the other end of the support band. The sponge strip is attached to a support pin which is attached to the support pin upper mounting projection and the support pin lower mounting projection of the entire surface mask, and a plate brazed to the reinforcing frame. It consists of an attached support pad.

[0008]

According to the present invention, since the glasses are completely built in the entire mask and the airtightness originally required for the entire mask is sufficiently obtained, safety can be ensured.
The force applied to the face by the elasticity and expansion and contraction of the support band is distributed to the support pad and the bridge of the nose, reducing the feeling of pressure from the glasses, making it possible to wear it for a long time easily and improve work efficiency. improves.

[0009] In addition, the mounting of the glasses on the entire mask is a very simple operation of inserting the upper and lower ends of the support pins of the glasses into the small holes of the upper mounting projection and the lower mounting projection of the entire mask. Also, the adjustment of the position of the glasses can be performed simply by shifting the support band up and down along the support pins, so that the handling of the glasses is simplified.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing the entire mask of the present invention mounted on a human head. ) And support pin lower mounting projections 5 (hereinafter referred to as “lower mounting projections 5”) are provided at regular intervals. In FIG. 1, the upper mounting projections 4 and the lower mounting projections 5 pass through the eye glass 3. I can see The upper mounting projection 4 and the lower mounting projection 5 are provided with small holes 6 such that the upper end and the lower end of the support pin 15 of the glasses for exclusive use of the mask of the present invention to be described later can be inserted. The upper mounting projection 4 and the lower mounting projection 5 are formed integrally with the mask body 1.

FIG. 2 is a perspective view of spectacles exclusively for full-face masks (hereinafter referred to as "glasses") of the present invention. The spectacles are integrally formed on a lens 10, a frame 11, a nose bridge support 12, and right and left ends of the frame 11. A hook 13 provided, a support band 14 having a thin hole for connecting to the hook 13 at one end of a folded rubber molded body having elasticity and elasticity, and a narrow hole provided at the other end of the support band 14. A support pin 15 to be inserted into the support frame, a reinforcing frame 16, and a support pad 17 are provided.

The support pad 17 is composed of a plate 18 to be brazed to the reinforcing frame 16 and a sponge band 19 to be attached to the plate 18. The hook-shaped portion of the reinforcing frame 16 is about 10 mm. Together with the thickness of the sponge band 19, it functions to keep the distance between the lens 10 and the eyeball normal.

Then, the upper end and the lower end of the support pins 15 of the glasses are inserted into the small holes 6 of the upper mounting projections 4 and the lower mounting projections 5 of the entire mask, respectively, and the glasses are mounted on the entire mask. Before putting on the face, a mask is put on the face in advance to check whether the positional relationship between the glasses and the eyes is normal. If improper, the support band 14 is moved up and down along the support pins 15 so as to be adjusted to a normal position.

When the full-face mask is worn on a human head, the same operation as wearing a normal full-face mask without glasses is performed on the human head (see FIG. 3).
At the same time as the nose bridge support 12 of the glasses abuts the nose bridge, the support pad 17 abuts on the forehead, so that the positional relationship between the lens 10 and the eyes is normally maintained, and the elasticity and expansion and contraction of the support band 14 Is stably fixed to the face. At this time,
Since the force applied to the face by the elasticity and expansion and contraction of the support band 14 is distributed between the support pad 17 and the bridge of the nose bridge 12, the feeling of pressure from the glasses is reduced, and wearing for a long time becomes easy.

[0016]

[Effects of the Invention] As described above, according to the present invention,
The glasses are completely built into the mask and the required airtightness of the mask can be obtained sufficiently, ensuring safety and supporting the force applied to the face by the elasticity and expansion and contraction of the support band. Since it is distributed between the pad and the support of the bridge of the nose, the feeling of pressure from the glasses is reduced, so that wearing for a long time can be made easier and the effect that the working efficiency is improved is exhibited.

Also, the mounting of the glasses on the entire mask is a very simple operation of merely inserting the upper and lower ends of the support pins of the glasses into the small holes of the upper mounting projection and the lower mounting projection of the entire mask. In addition, the adjustment of the position of the glasses can be performed simply by shifting the support band up and down along the support pins, so that there is an effect that the handling of the glasses is simplified.
