The mouth shield of one embodiment of the present invention and a method of using the mouth shield will be described with reference to Figures 1 to 11.

(Figs. 1 to 6)
M shown in FIG. 1 is a mouth shield, which is disposed in front of the wearer's mouth to block droplets from the mouth.
Reference numeral 1 denotes a support member that comes into contact with the face, 2 denotes an attachment means for fixing the support member in a predetermined position on the wearer's face, and 3 denotes a main body that is rotatably supported by the support member 1 and rotates under its own weight.
For example, as shown in Figure 6, the rotatable state may be such that an engaging portion (shaft) 1T is provided on the support member 1 and a support portion 33 having an engaged portion (hole) 33a that engages with this engaging portion (shaft) 1T is provided on the main body 3, or conversely, an engaging portion (shaft) is provided on the main body 3 and a support portion 11 having an engaged portion (hole) that engages with this engaging portion (shaft) is provided on the support member 1.
In addition, the part of the support member 1 that comes into contact with the face is the bridge of the nose in Fig. 1. In this case, the support member 1 comes into contact with the bridge of the nose.

The support member 1 described above may be, for example, one that abuts against the bridge of the nose as shown in Fig. 1, or may be an eyeglass frame 10 as shown in Figs. 7 to 11 described below. This eyeglass frame 10 may be fitted with an eye shield (e.g., a lens with prescription, a lens without prescription, or a cover that protects the eyes instead of a lens (eye protection shield), etc.), or may not be fitted with an eye shield.
The attachment means 2 may be, for example, an elastic band 21 as shown in FIG. 1, or a portion 22 that is hung on the ears at the end of a pair of temples of an eyeglass frame as shown in FIG. 7 described later.
In addition, the "eyeglasses frame" referred to in this invention is not limited to an "eyeglasses frame" in the narrow sense having a so-called "rim" to which the lenses are fixed, but also includes an "eyeglasses frame" in the broad sense having no "rim" to which the lenses are fixed, for example, a right temple, a left temple, and a support member having no "rim" connecting the left temple and the right temple.
The main body 3 also has a shielding portion 31 and a support portion 32 that supports the shielding portion 31. The shielding portion 31 is, for example, a transparent (or semi-transparent or non-transparent) plastic (for example, polyethylene terephthalate), and the support portion 32 is curved to fit the face.

When the face of a wearer of the above-mentioned mouth shield M is positioned vertically, as shown in FIG. 1(a), the main body 3 automatically hangs down due to its own weight without touching the main body 3, and the main body 3 faces the mouth of the wearer.
When the wearer tilts his/her face forward, the main body 3 automatically sags down due to its own weight, as shown in FIG. 1(b), and the open area W in the vicinity of the wearer's mouth increases.

Therefore, according to the above-mentioned mouth shield M (method of using the mouth shield), when the wearer's face is positioned vertically, as shown in Figure 1 (a), the body 3 automatically sags due to its own weight without touching it, so that the body 3 faces the wearer's mouth and blocks droplets from the mouth when talking. Also, when the wearer tilts his/her face forward, as shown in Figure 1 (b), the body 1 automatically sags due to its own weight, so that the open area W near the wearer's mouth is expanded, and it is possible to, for example, eat without touching the body 3, thereby obtaining a mouth shield (method of using the mouth shield) that is easy to use.
The above-described mouth shield M (method of using the mouth shield) allows the user to wear the mouth shield without feeling uncomfortable, as compared to conventional mouth shields that are fastened to the chin.

(FIGS. 7 to 11)
Next, the mouth shield M (method of using the mouth shield) will be described with reference to Figs.
The support member 1 that comes into contact with the face is an eyeglass frame that is worn on the face.
A main body 3 is provided which is rotatably supported by the eyeglass frame 1 and rotates under its own weight.
When the wearer's face is positioned vertically, as in FIG. 1( a ), the main body 3 automatically sags due to its own weight without touching it, so that the main body 3 faces the wearer's mouth, and when the wearer's face is tilted forward, the main body 3 automatically sags due to its own weight, as in FIG. 1( b ), so that the open area W near the wearer's mouth expands.
Therefore, similarly to the above-mentioned mouth shield M (method of using a mouth shield), according to the mouth shield M (method of using a mouth shield) shown in Figures 7 to 11, when the wearer's face is positioned vertically, as shown in Figure 1 (a), the body 3 automatically hangs down due to its own weight without touching the body 3, so that the body 3 faces the wearer's mouth and blocks droplets from the mouth when talking. Also, when the wearer tilts his/her face forward, as shown in Figure 1 (b), the body 1 automatically hangs down due to its own weight, so that the open area W near the wearer's mouth is expanded, and therefore, for example, the wearer can eat without touching the body 3, and a mouth shield that is easy to use can be obtained.
The above-described mouth shield M (method of using the mouth shield) allows the user to wear the mouth shield without feeling uncomfortable, as compared to conventional mouth shields that are fastened to the chin.
As for the freedom of rotation, as described above, for example, as shown in FIG. 11 , an engaging portion (axis) 1T may be provided on the eyeglass frame (supporting member) 1, and a support portion 33 having an engaged portion (hole) 33a that engages with this engaging portion (axis) 1T may be provided on the main body 3, or conversely, an engaging portion (axis) may be provided on the main body 3, and a support portion 11 having an engaged portion (hole) that engages with this engaging portion (axis) may be provided on the eyeglass frame (supporting member) 1.

12 to 17 are mouth shields M of other embodiments different from those shown in FIGS. 7 to 11. Reference numeral 100 shown in FIGS. 13 and 15 denotes a rotation prevention holding means for preventing the rotation of the main body 3 and for maintaining the rotation-prevented state. This rotation prevention holding means 100 prevents the main body 3 from rotating and for maintaining the rotation-prevented state, so that the main body 3 can be prevented from swaying, for example, when talking outside in the wind.
The rotation prevention holding means 100 has, for example, an elastically deformable locking portion 100T provided on the main body 3 and an engaged portion 100U provided on the support member 1, and the main body 3 is supported by the support member 1 in a freely rotatable manner while being free to move relative to the support member 1 (see Figures 12 and 13).To fix the main body 3 to the support member 1, when the locking portion 100T in the state of Figure 13 is pushed toward the engaged portion 100U, the locking portion 100T deforms and overcomes the engaged portion 100U, and the locking portion 100T engages with the engaged portion 100U (see Figures 14 and 15). To release the lock, when a force is applied to move the locking portion 100T in the state of FIG. 15 away from the locked portion 100U, the locking portion 100T deforms and overcomes the locked portion 100U, and the locking portion 100T moves away from the locked portion 100U (transitioning from the state of FIG. 15 to the state of FIG. 13).
