Description

The present invention relates to a mask.

As an example of the mask, there is one described in the Registered Utility Model Gazette of Utility Model Registration No. 322109.
FIG. 5 is a front view of the mask 10 described in the same publication, and FIG. 6 is a perspective view of the mask 10 assuming a usage state.
As shown in FIGS. 5 and 6, the mask 10 includes a main body portion 11 having a size covering the user's nose and mouth, and a pair of rubber cords 12A attached to both sides of the main body portion 11 in the left-right direction. It is composed of 12B and.

The main body portion 11 is made of a non-woven fabric, and a plurality of pleats 11A extending in the lateral direction are formed on the surface thereof. As shown in FIG. 6, when the mask 10 is used, the mask 10 has a three-dimensional shape.
As shown in FIG. 5, one end of each of the elastic cords 12A and 12B is attached in a semicircular shape as a whole so as to be located above the other end, and each of the elastic cords 12A and 12B is hung on each ear of the user. The body portion 11 is fixed to the user's nose and mouth.
FIG. 7 is a side view of the state when the mask 10 is actually worn.

The mask 10 has a problem that it shifts downward while being worn and the nose is exposed. The reason why such a problem occurs is as follows.
As shown in FIG. 7, when the mask 10 is worn, the upper portion 12AA of the elastic cord 12A hangs above the user's ear, and the lower portion 12AB of the elastic cord 12A hangs below the user's ear.
In this case, in the conventional mask represented by the mask 10, both the upper portion 12AA and the lower portion 12AB of the elastic cord 12A face downward. Specifically, the upper portion 12AA of the elastic cord 12A extends in a state of being inclined downward from above the user's ear, and the lower portion 12AB of the elastic cord 12A is also the same as the upper portion 12AA of the user's ear. It extends from the bottom to the bottom.

Therefore, the action line 13 of the resultant force of the tensile force due to the upper portion 12AA of the rubber cord 12A and the tensile force due to the lower portion 12AB of the rubber cord 12A also points downward as shown by the arrow 14. As a result, when the user moves his / her mouth while wearing the mask 10, a downward force acts on the entire mask 10, and the mask 10 gradually downwards (arrow 14) with the passage of time. Will slide down (in the direction of).
If the tensile force of the elastic cords 12A and 12B is increased, the slipping off of the mask 10 may be solved, but then, the traces of the elastic cord will be left on the user's face, which is not good for the user. Increasing the tensile force of the elastic cords 12A and 12B is not considered as a solution for the mask 10 to slip off.

It is a perspective view when the use state of the conventional mask shown in FIG. 5 is assumed. FIG. 5 is a side view of a state when the conventional mask shown in FIG. 5 is actually worn.

(First Embodiment)
FIG. 1 is a side view when the mask 100 according to the first embodiment of the present invention is worn.
The mask 100 according to the present embodiment includes a main body portion 110 having a size covering the user's nose 130 and mouth 140, and a pair of elastic cords 121 and 122 attached to both sides of the main body portion 110 in the left-right direction, respectively. In FIG. 1, only the elastic string 121 is shown).
The main body portion 110 is made of, for example, a non-woven fabric, and has a shape capable of covering the user's nose 130 and mouth 140, similar to the conventional mask 10 shown in FIG.

As shown in FIG. 1, one end 121A, 122A of each elastic string 121, 122 is located above the other ends 121B, 122B, and each elastic string 121, 122 is semicircular (or laterally oriented) as a whole. Attached to the U-shape), the elastic body strings 121 and 122 are hung on each of the user's ears 150 so that the main body portion 110 is fixed to the user's nose 130 and mouth 140. ..
In the mask 100 according to the present embodiment, as shown in FIG. 1, each of the elastic cords 121 and 122 is located below each of the elastic cords 121 and 122 when the user attaches the mask 100. The lower string portions 121C and 122C are attached to the main body portion 110 so as to be substantially horizontal toward the user's nose 130.

Specifically, the lower cord portions 121C and 122C of the elastic cords 121 and 122 are located within the height range of the user's nose 130 when viewed from the lateral direction, and extend substantially horizontally. It has become like.
Here, the "almost horizontal direction" means that the vehicle is within a range of ± 5 degrees with respect to the horizontal direction. Within the range of this inclination, substantially the same effect as in the state where the lower string portions 121C and 122C are extended in the horizontal direction can be obtained.
As shown in FIG. 7, when the conventional mask 10 is worn, both the upper portion 12AA and the lower portion 12AB of the elastic cord 12A face downward, so that the tensile force of the upper portion 12AA of the elastic cord 12A and the lower portion of the elastic cord 12A The line of action 13 of the resultant force with the tensile force by the portion 12AB also points downward as shown by the arrow 14. Therefore, when the user moves his / her mouth while wearing the mask 10, a downward force acts on the entire mask 10, and the mask 10 gradually slides downward (in the direction of the arrow 14). It was supposed to fall.

On the other hand, in the mask 100 according to the present embodiment, the lower string portions 121C and 122C located below the elastic body strings 121 and 122 are the height of the user's nose 130 when viewed from the lateral direction. It is located within the range of and is set to extend almost horizontally. Therefore, the lower string portions 121C and 122C pull the user's nose 130 on the extension line thereof, and in addition, the upper string portions 121D and 122D located above the elastic body strings 121 and 122 are the main bodies. Since a tensile force is applied to the main body portion 110 in the direction of pulling up the upper end and the lower end of the portion 110, a downward sliding force does not act on the mask 100 unlike the conventional mask 10.
As described above, the mask 100 according to the present embodiment can solve the problem in the conventional mask 10 that the main body portion 11 gradually slides down while being worn, and the mask 100 can be used. The anxiety of slipping down can be eliminated, and the mask 100 can be worn for a long time with peace of mind.

The mask 100 according to the present embodiment is not limited to the above structure, and various modifications can be made.
In the mask 100 according to the present embodiment, the lower string portions 121C and 122C of the elastic body strings 121 and 122 are set to extend substantially in the horizontal direction when viewed from the lateral direction, but the lower string portion 121C , The direction in which 122C extends is not limited to this.
FIG. 2 is a side view of the wearing state of the mask 100A according to the modified example of the mask 100 according to the first embodiment.

As shown in FIG. 2, the lower cord portions 121C and 122C located below the elastic cords 121 and 122 are directed upward from below the user's ear 150 toward the nose 130 when viewed from the side. As described above, it can be attached to the main body portion 110.
By attaching the lower string portions 121C and 122C upward toward the user's nose 130, the same effect as in the first embodiment can be obtained.
For example, by determining the positions of the other ends (lower ends) 121B and 122B so that the positions of the other ends (lower ends) 121B and 122B of the elastic strings 121 and 122 are higher than the positions shown in FIG. The lower cord portions 121C and 122C of the elastic cords 121 and 122 can be made to face upward toward the user's nose 130.
The shape of the main body portion 110 is not limited to the three-dimensional (three-dimensional) shape as shown in FIG. 1, but may be a two-dimensional shape such as a horizontally long rectangle when viewed from the front. , Not limited to a particular shape.

(Second embodiment)
In the mask 100 according to the first embodiment described above, the orientation of the lower cord portions 121C, 122C of the elastic cords 121, 122 is set horizontally toward the user's nose 130, or the user's nose 130. By setting the mask 100 upward, the mask 100 was prevented from slipping down.
The mask 200 according to the second embodiment described below can be obtained by making the shape of the main body portion 110 into a specific shape in addition to the orientation of the lower cord portions 121C and 122C of the elastic cords 121 and 122. It prevents slipping off.
FIG. 3 is a view seen from the lateral direction when the mask 200 according to the present embodiment is worn.

As shown in FIG. 3, the position 210A where the upper end of the main body portion 210 of the mask 200 contacts the user's nose 130 and the position 210B where the ends 121A and 122A of the elastic cords 121 and 122 are attached to the main body portion 210. In between, the main body portion 210 is formed in a downwardly convex curved shape 215.
Similarly, between the position 210C where the main body portion 210 is in contact with the user's jaw and the position 210D where the lower ends 121B and 122B of the elastic cords 121 and 122 are attached to the main body portion 210, the main body portion 210 is upward. It is formed in a convex curved shape 216.
Assuming that the straight line connecting the position 210A where the main body portion 210 is in contact with the user's nose 130 and the position 210B where the ends 121A and 122A of the elastic cords 121 and 122 are attached to the main body portion 210 is L1, the curved shape with respect to the straight line L1. The maximum depth D1 of 215 is set within the range of 10% to 20% of the length of the straight line L1.

Similarly, assuming that the straight line connecting the position 210C where the main body portion 210 is in contact with the user's jaw and the position 210D where the lower ends 121B and 122B of the elastic strings 121 and 122 are attached to the main body portion 210 is L2, the straight line is relative to the straight line L2. The maximum depth D2 of the curved shape 216 is set within the range of 10% to 20% of the length of the straight line L2.
Further, assuming that the straight line L3 connects the position 210A and the position 210F in which the upper string portions 121D and 122D located above the elastic body strings 121 and 122 hang on the user's ear 150, the maximum curve shape 215 with respect to the straight line L3 is obtained. The depth D3 is set to be within the range of 15% to 20% of the length of the straight line L3. Most preferably 15%.

Similarly, assuming that the straight line connecting the position 210C and the position 210G where the lower string portions 121C and 122C located below the elastic body strings 121 and 122 hang under the user's ear 150 is L4, the curved shape 216 with respect to the straight line L4. The maximum depth D4 of is set to be within the range of 20% to 25% of the length of the straight line L4. Most preferably 20%.
By forming the curved shapes 215 and 216 on the upper and lower sides of the main body portion 210 in this way, the positions 210A and 210F and each position 210C are independent of the tensile force of the elastic cords 121 and 122. And 210G will pull each other, so it is possible to prevent the main body part 210 from slipping off, and it is also possible to reduce the gap between the fabric of the main body part 210 and the user's skin. is there.

In particular, as shown in FIG. 3, the positions 210A and 210F are set to be located at substantially the same height when the mask 200 is worn, and the force of pulling each other can be maximized. It is possible.
Further, in the mask 200 according to the present embodiment, the length between the position 210A and the position 210F and the length between the most advanced position 210E and the position 210G of the user's jaw are set to be substantially equal. .. By setting both lengths to be substantially equal in this way, it is possible to prevent the main body portion 210 of the mask 200 from slipping. In particular, the more the position 210E is moved upward (that is, the lower end of the main body portion 210 does not touch the user's chin), the more it is possible to prevent the main body portion 210 from slipping off.
In addition, "almost equal" means that one is within the range of ± 5% of the other.

Further, by providing the main body portion 210 with a notch having curved shapes 215 and 216, the area where the main body portion 210 covers the user's face is reduced as compared with the case where such a notch is not provided.
Further, in the mask 200 according to the present embodiment, the position 210D in which the lower ends 121B and 122B of the elastic strings 121 and 122 are attached to the main body portion 210 is set to a position higher than that of the conventional mask 10. Therefore, the area covered by the main body portion 210 around the user's chin, neck, and gills is smaller than that of the conventional mask 10.
In this way, for the user, the area where heat is trapped in the face (that is, the area covered by the main body portion 210) is reduced, so that it is possible to reduce the heat buildup in the face. It is especially effective in hot weather.
The shape of the main body portion 210 between the position 210C of the main body portion 210 and the tip position 210E of the user's jaw may be linear, or may have a curved shape that is convex upward or downward. It is also possible to form a downwardly convex curved shape from the position 210D to the position 210E of the main body portion 210.

(Third embodiment)
