Description

[Detailed description of the invention] (Technical field) The present invention relates to a full-face mask that covers the entire face in order to eliminate harmful substances in the air, such as radioactive dust and toxic gas, from inhaled air. This invention relates to a mask that allows glasses to be attached to the inside of the mask for the wearer.

(Prior Art) In recent years, it has become necessary to operate binoculars and other machines by wearing a two-lens full-face mask that has two eyeglasses corresponding to the wearer's two eyes. In such cases, it is desirable to place the eyeglasses closer to the wearer's eyes in order to improve workability or to obtain a larger field of view with smaller eyeglasses.

On the other hand, if a glasses user wears a mask while wearing glasses that he or she uses on a daily basis, the glasses will get in the way and the mask will not be airtight. For this reason, when contact lenses were used, the eyes became dry due to inhalation, and some people complained of eye pain. Therefore, a mask that can be used with glasses is required.

A mask that can be used in combination with conventional eyeglasses is one that has mounting pins 3 at both ends of a glasses frame 2 into which two lenses 1 are fitted, as shown in FIG. In this way, the eye glasses 4 fitted into the mask were inserted into holes provided in the face pieces 5 at both ends to be fixed. However, the shape and fixing method of such glasses has the following drawbacks.

(1) Since the pair of eyeglass lenses 1 are fitted into the left and right eyeglass frames 2, the eyeglass lenses 1 cannot be brought close to the eyeglasses 4. Therefore, the gap between the wearer's eyes and the eyeglass 4 is too wide, resulting in a narrow field of vision and making it very inconvenient to operate binoculars or other machines.

(2) When conventional glasses as shown in Figure 1 are attached to a mask shaped so that the wearer's eyes and eye glasses 4 are brought close together, the glasses do not function as glasses when they come into contact with the wearer's face. Also, it is impossible to wear the mask correctly.

(3) In conventional glasses, the left and right lenses 1 are integrated, so when attaching them to the mask, it is necessary to balance the left and right lenses at the same time.
It was very difficult to align.

(Purpose of the invention) In order to eliminate the drawbacks of the above-mentioned conventional example, the present invention provides a full-face mask in which a pair of individual frame glasses lenses are detachably attached to the inside of the eye glasses of the mask. It is. This makes it possible to bring the spectacle lens closer to the eyeglass, thereby reducing the distance between the wearer's eyes and the eyeglass. Moreover, it becomes easy to adjust the spectacle lenses to an appropriate position according to the facial structure of the wearer.

(Example) Hereinafter, an example will be described in detail based on the drawings. FIG. 3 shows glasses according to an embodiment of the present invention. Reference numeral 11 denotes a spectacle lens, which is fitted into an independent lens frame 12, and the lens frame 12 has one mounting pin 13 at the part corresponding to the outer corner of the eye, and two bent pins at the part corresponding to the inner corner of the eye. An ivy mounting pin 14 is provided.

FIG. 4 shows the glasses attached to the inside of the eye glasses 4 of the mask. eye glass 4
One small hole 15 is provided in the face piece 5 into which the eyeglass lens 11 is fitted, in a portion corresponding to the outer corner of the eye, and the tip of the attachment pin 13 is inserted into this small hole 15. Further, a plurality of small holes 16 are arranged at a pitch in a portion corresponding to the inner corner of the eye, and the tip of the attachment pin 14 is inserted into a properly selected small hole 16 among them.

In this way, the glasses attached to the facepiece 5 are placed very close to the eyeglasses 4, as shown in FIG. The distance between the eye and the eye glass 4 can be narrowed. Additionally, people with large facial bones generally have a longer distance from their chin to their eyes and a wider distance between their eyes than people with smaller facial bones. In other words, when wearing a mask, people with large facial bones will have their eyes positioned above and outside the eyeglasses 4 when the chin is taken as a reference; Located below and inside. On the other hand, if the position of the spectacle lens 11 is rotated around the small hole 15 into which the mounting pin 13 is inserted as shown in FIG. 6c and fixed at an appropriate position, the wearer's eye The mounting position of the glasses can be easily adjusted according to the position of the glasses.

(Effects of the invention) As explained above, according to the invention, the spectacle lenses can be attached close to the eyeglasses, and therefore the distance between the eyeglasses and the wearer's eyes can be narrowed. , the field of view becomes wider, and it becomes much easier to operate binoculars, other devices, and machines. Further, there are effects such as being able to easily adjust the position of the glasses according to the position of the wearer's eyes.
