The reason is that there are

[0014] thisIn this configuration, the plate-shaped shield is supported by the shield support, and the lateral center of the shield support and the lateral center of the attachment are connected while being spaced apart, allowing the shield to be positioned sufficiently away from the user's face. Furthermore, the lateral center of the attachment is supported by the user's nose at the nose hook, allowing the shield support and the shield connected to the lateral center of the attachment to be accurately positioned relative to the user's nose and mouth, eliminating the need to make the shield larger than necessary. This effectively prevents the user's face from becoming too hot and stuffy. Also, In this configuration, by using the left ear hook portion and the right ear hook portion, the attachment portion can be easily and stably attached to the face of a user who does not wear glasses, and by using the left temple hook portion and the right temple hook portion, the attachment portion can be easily and stably attached to the face of a user who wears glasses.

[0015] To achieve the above objectives, The features of the splash prevention mouth shield of the present invention are: the shield is provided with a transparent, plate-like shield portion that covers the nose and mouth of a user; a shield support portion that supports the shield portion in a curved state that bulges forward when viewed from the front; a mounting portion that is attached to the user's face; and a connecting portion that connects the shield support portion and the mounting portion in a state where they are spaced apart from each other, wherein the left-right center portion of the shield support portion and the left-right center portion of the mounting portion are connected via the connecting portion, and the mounting portion has a left ear hook portion at the rear end on the left side that is hung over the left ear of the user, a right ear hook portion at the rear end on the right side that is hung over the right ear of the user, and a nose hook portion at the left-right center that is hung over the user's nose, A left rear end portion of the wearing part is selectively and detachably provided with either a left ear hook portion to be hung on the left ear of the user or a left temple hook portion to be hung on the left temple of the eyeglasses, and a right rear end portion of the wearing part is selectively and detachably provided with either a right ear hook portion to be hung on the right ear of the user or a right temple hook portion to be hung on the right temple of the eyeglasses, The portion between the left ear hook portion and the nose hook portion and the portion between the right ear hook portion and the nose hook portion each extend below the user's eyes and come into contact with the user's cheek.

[0016] thisIn this configuration, the plate-shaped shield is supported by the shield support, and the lateral center of the shield support and the lateral center of the attachment are connected while being spaced apart, allowing the shield to be positioned sufficiently away from the user's face. Furthermore, the lateral center of the attachment is supported by the user's nose at the nose hook, allowing the shield support and the shield connected to the lateral center of the attachment to be accurately positioned relative to the user's nose and mouth, eliminating the need to make the shield larger than necessary. This effectively prevents the user's face from becoming too hot and stuffy. Also, In this configuration, by using the left ear hook portion and the right ear hook portion, the attachment portion can be easily and stably attached to the face of a user who does not wear glasses, and by using the left temple hook portion and the right temple hook portion, the attachment portion can be easily and stably attached to the face of a user who wears glasses.

[0017] Another feature of the splash-proof mouth shield of the present invention is that the shield support part is provided at the upper end of the shield part, the connecting part has an arm part extending in the front-to-rear direction, the front end of the arm part is connected to the shield support part, and the rear end of the arm part is attached so as to be rotatable in the vertical direction relative to the mounting part. In this configuration, By rotating the arm, the shield can be moved between a lowered position that covers the user's nose and mouth and an elevated position that moves the shield away from the user's nose and mouth. When the shield is in the elevated position, a large amount of space is secured in front of the user's mouth, allowing the user to eat and drink while wearing the splash prevention mouth shield. The shield support, to which the front end of the arm is connected, is located at the upper end of the shield, so when the arm is rotated to move the shield to the elevated position, the upper end of the shield does not come into contact with the user's face.

[0018] Another feature of the splash-proof mouth shield of the present invention is that the rear end of the arm portion is provided with a protrusion that protrudes radially from the pivot axis, and the attachment portion is provided with a stopper portion against which the protrusion is pressed and elastically deformed when the arm portion is pivoted, and when the arm portion is pivoted upward, the protrusion hits the restored stopper portion, thereby preventing the arm portion from pivoting downward. In this configuration, When the protrusion hits the stopper, the arm is prevented from rotating downward, so that the shield can be held in the raised position when the user is eating or drinking.

[0019] Another feature of the splash-proof mouth shield of the present invention is that the shield support portion has a plurality of protrusions, and the shield portion has a plurality of through holes that are detachably fitted to each of the plurality of protrusions. In this configuration, Since the multiple protrusions of the shield support part and the multiple through holes of the shield part are detachably engaged, the shield part can be replaced with another shield part of a different size, and a damaged shield part can be replaced with a new shield part.

[0020] Another feature of the splash-proof mouth shield of the present invention is that a rod-shaped left shield temple is curved and U-shaped so as to bulge downward between the rear end of the left side of the mounting part and the center in the left-right direction, and a rod-shaped right shield temple is curved and U-shaped so as to bulge downward between the rear end of the right side of the mounting part and the center in the left-right direction.

[0021] In this configuration, the shield temples on both sides are curved downwards in a U-shape, preventing them from interfering with the temples of the glasses and providing a comfortable fit. Furthermore, the shield temples are configured so that the U-shaped portions open elastically, allowing them to be deformed to fit the size of the user's head or face, ensuring a stable fit.

[0022] Another feature of the splash-proof mouth shield of the present invention is that the distance between the lower part of the left shield temple and the lower part of the right shield temple is set to be narrower than the distance between the user's left and right cheeks.

[0023] In this configuration, the lower portions of the left and right shield temples can be brought into contact with the user's cheeks, making it difficult for the mounting portion to move vertically. Therefore, if the connecting portion, shield support portion, and shield portion as a whole are configured to be rotatable vertically, they can be easily rotated by the user's hand.

[0024] Another feature of the splash-proof mouth shield according to the present invention is that the shield support part, the mounting part and the connecting part are made of a transparent or translucent material.

[0025] In this configuration, the shield support portion, attachment portion, and connecting portion are formed from a transparent or translucent material, and this, combined with the transparency of the shield portion, makes the splash prevention mouth shield as a whole less noticeable.

DETAILED DESCRIPTION OF THE INVENTION

[0027] Hereinafter, an embodiment of a splash prevention mouth shield according to the present invention will be described with reference to the drawings.

[0028] (First embodiment) FIG. 1 is a perspective view showing the splash prevention mouth shield 10 according to the first embodiment in use. FIG. 2 is a perspective view showing the configuration of the splash prevention mouth shield 10. FIG. 3 is a left side view showing the configuration of the splash prevention mouth shield 10. FIG. 4 is an exploded perspective view showing the mounting structure of the shield part 12 relative to the shield support part 14. FIG. 5 is an exploded perspective view showing the mounting structure of the connecting part 18 relative to the mounting part 16. Note that the directions of "front, back, left, right, up, down" used in the following description are directions as seen from the user M, and correspond to the directions indicated by arrows in FIGS. 1, 2, 3, and 4.

[0029] The droplet prevention mouth shield 10 shown in Figure 1 is a sanitary device used as a measure against droplet infection of viruses, and is equipped with a shield part 12 that covers the nose and mouth of the user M, a shield support part 14 that supports the shield part 12, an attachment part 16 that is attached to the face F of the user M, and a connecting part 18 that connects the shield support part 14 and the attachment part 16.

[0030] The splash prevention mouth shield 10 of this embodiment is configured to be capable of selectively assuming a first state shown by a solid line in FIG. 1 and a second state shown partially by a two-dot chain line in FIG. 1. The first state is the state during normal use, in which the shield portion 12 is positioned to cover the nose and mouth of the user M. The second state is the state when the shield portion 12 is not needed, such as when eating or drinking, in which the shield portion 12 is positioned at a position above and away from the position covering the nose and mouth of the user M. The position of the shield portion 12 (solid line) in the first state is the "lowered position P1," and the position of the shield portion 12 (two-dot chain line) in the second state is the "raised position P2."

[0031] 2, the shield part 12 is a transparent, plate-like member made of synthetic resin such as polyethylene terephthalate (PET), and is formed into a substantially rectangular shape with two rounded corners on the bottom. The size of the shield part 12 is determined so that it can completely cover the nose and mouth when placed in front of the face F (FIG. 1).

[0032] More specifically, the vertical length of shield part 12 is set to be slightly longer than the length from the root of the nose to the bottom of the chin on face F (Fig. 1), and the horizontal length of upper end 12a of shield part 12 is set to be slightly longer than the horizontal length of the part of face F (Fig. 1) corresponding to upper end 12a. In addition, the overall horizontal length (width) of shield part 12 is set to become gradually shorter (narrower) from upper end 12a to lower end 12b.

[0033] 2, the upper edge 12c of the shield part 12 extends substantially horizontally, and the lower edge 12d of the shield part 12 is curved so as to bulge downward. The boundaries between the lower edge 12d and the left and right side edges 12e, 12f of the shield part 12 are formed in a rectangular shape with rounded corners, i.e., a smoothly curved shape. The shield part 12 as a separate component is formed in a flat plate shape, and when attached to the shield support part 14, it is elastically bent so as to bulge forward in a front view.

[0034] 4, a plurality of (five in this embodiment) through holes 22 are provided at intervals in the left-right direction at the upper end 12a of the shield part 12. A plurality of (five in this embodiment) protrusions 20 (described later) are detachably fitted therein. The thickness of the shield part 12 is not particularly limited, but is set to 0.25 mm in this embodiment.

[0035] As shown in Fig. 4, the shield support part 14 is a transparent or translucent rod-shaped member made of ABS resin or the like, and is curved so as to bulge forward when viewed from the front. The vertical length (height) of the shield support part 14 is set to be longer than the length (thickness) in a direction perpendicular to the vertical direction. A plurality of (five in this embodiment) protrusions 20 are provided on the inner surface (i.e., rear surface) 14a of the shield support part 14 at intervals in the length direction (i.e., left-right direction) and are detachably fitted into a plurality of (five in this embodiment) through holes 22 of the shield part 12. The shield part 12 is attached to the inner surface (i.e., rear surface) 14a of the shield support part 14 by fitting each of the protrusions 20 of the shield support part 14 into each of the through holes 22 of the shield part 12.

[0036] As shown in FIG. 4 , the protrusion 20 is mushroom-shaped and includes a head 20a and a stem 20b. The diameter of a first circumscribing circle circumscribing the head 20a is set slightly larger than the inner diameter of the through hole 22, and the diameter of a second circumscribing circle circumscribing the stem 20b is set smaller than the diameter of the first circumscribing circle. When the shield part 12 is attached to the inner surface (i.e., rear surface) 14a of the shield support part 14, each protrusion 20 of the shield support part 14 is inserted into and engaged with each through hole 22 of the shield part 12. When the head 20a of the protrusion 20 passes through the through hole 22, the diameter of the through hole 22 elastically expands. Therefore, after the head 20a passes through the through hole 22, the inner diameter of the restored through hole 22 becomes smaller than the diameter of the first circumscribing circle, and the protrusion 20 is unlikely to come off the through hole 22.

[0037] 4, the inner surface (i.e., rear surface) 14a of the shield support part 14 is curved so as to bulge forward in a front view, and the flat shield part 12 is attached to the shield support part 14 so as to fit along this inner surface (i.e., rear surface) 14a. Therefore, the shield support part 14 supports the shield part 12 in a curved state so as to bulge forward in a front view.

[0038] As shown in Fig. 2, the wearing unit 16 has a nose hook portion 24 that is placed around the nose of the user M (Fig. 1), a left ear hook portion 26 that is placed around the left ear of the user M, and a right ear hook portion 28 that is placed around the right ear of the user M. Also, as shown in Fig. 4, the wearing unit 16 has a left attachment portion 32 to which the left arm portion 30 of the connecting unit 18 is rotatably attached, and a right attachment portion 36 to which the right arm portion 34 of the connecting unit 18 is rotatably attached. Furthermore, as shown in Fig. 2, the wearing unit 16 has a left shield temple 38 that extends from the left ear hook portion 26 toward the nose hook portion 24, and a right shield temple 40 that extends from the right ear hook portion 28 toward the nose hook portion 24.

[0039] Of the above-mentioned components constituting the mounting part 16, the nose piece 24, left attachment part 32, right attachment part 36, left shield temple 38, and right shield temple 40 are made of transparent or translucent ABS resin or the like. Each component constituting the mounting part 16 will be described in detail below.

[0040] As shown in Fig. 4, nose hook 24 is an inverted U-shaped portion that is positioned so as to straddle the nose of user M (Fig. 1). Plate-shaped nose pads 42, 44 with smooth surfaces (not shown) that come into contact with the left and right nostrils (portions on both sides of the bridge of the nose) of user M (Fig. 1) are provided at the lower end of nose hook 24, i.e., the left and right portions corresponding to the open ends of the inverted U.

[0041] As shown in Fig. 2, left ear hook 26 is a part that is hooked onto the left ear of user M in the same way as the temple of ordinary eyeglasses, and is formed in a rod shape from an elastic material such as silicone. As shown in Fig. 3, the front end of left ear hook 26 is provided with a cylindrical mating hole 48 that fits with mating protrusion 46 provided at the rear end of left shield temple 38.

[0042] As shown in Figure 2, the right ear hook 28 is a portion that is hooked onto the right ear of the user M in the same manner as the temple of ordinary eyeglasses, and is formed in a rod shape from an elastic material such as silicone. Although not shown, the front end of the right ear hook 28 is provided with a cylindrical mating hole that fits into the mating protrusion provided at the rear end of the right shield temple 40. Note that the right ear hook 28 in this embodiment is configured bilaterally symmetrically with the left ear hook 26.

[0043] 5, the left attachment part 32 rotatably supports the left arm part 30 on the upper surface of the left nose pad 42, and has two walls 50a, 50b that are arranged facing each other and sandwich the left arm part 30 from the left and right, and two protruding shafts 52a, 52b that are provided on the facing inner surfaces of the two walls 50a, 50b. The left attachment part 32 also has a plate-shaped stopper part 54 that connects the rear ends of the two walls 50a, 50b and prevents the left arm part 30 from rotating.

[0044] The right attachment part 36 shown in FIG. 4 is a part that rotatably supports the right arm part 34 on the upper surface of the right nose pad 44, and is configured bilaterally symmetrical with respect to the left attachment part 32.

[0045] As shown in Figure 2, the left shield temple 38 is a rod-shaped portion connecting the nose hook 24 and the left ear hook 26, and is curved downward to form a U-shape. In this case, the U-shaped portion is formed to expand elastically. The front end of the left shield temple 38 is connected to the left nose pad 42 of the nose hook 24, and the rear end of the left shield temple 38 is provided with a connection portion 56 to which the left ear hook 26 is detachably connected.

[0046] 3, the connecting part 56 has a rod-shaped main body 56a that is continuous with the left ear hook part 26 without any steps, and the rear end of the main body 56a is provided with a mating projection 46 that is inserted into and mated with a mating hole 48 provided in the left ear hook part 26. The mating projection 46 is formed in a cylindrical shape with an outer diameter slightly smaller than the inner diameter of the mating hole 48 provided in the left ear hook part 26, and the outer circumferential surface of the mating projection 46 is provided with a hemispherical protrusion 46a to prevent it from coming loose.

[0047] As shown in FIG. 2, the right shield temple 40 is a rod-shaped portion that connects the nose piece 24 and the right ear piece 28, and is configured symmetrically with respect to the left shield temple .

[0048] The distance between the lower part of the left shield temple 38 and the lower part of the right shield temple 40 shown in Fig. 2 is set to be narrower than the distance between the left and right cheeks of the user M shown in Fig. 1. Therefore, when the user M wears the splash prevention mouth shield 10 on his / her face F, these lower parts come into contact with the cheeks of the user M.

[0049] Focusing on the position of each part of the mounting unit 16, as shown in Fig. 2, the nose hook 24 is provided in the left-right center of the mounting unit 16, the left ear hook 26 is provided at the rear end of the left side of the mounting unit 16, and the right ear hook 28 is provided at the rear end of the right side of the mounting unit 16. Also, as shown in Fig. 4, the left attachment part 32 and the right attachment part 36 are provided in the left-right center of the mounting unit 16, on both left and right sides of the nose hook 24. As shown in Fig. 2, the left shield temple 38 is provided between the rear end of the left side of the mounting unit 16 and the left-right center, and the right shield temple 40 is provided between the rear end of the right side of the mounting unit 16 and the left-right center.

[0050] 2, connecting portion 18 connects the shield support portion 14 and the mounting portion 16 at their laterally central portions while they are spaced apart, and has a transparent or semi-transparent rod-shaped left arm portion 30 and a right arm portion 34 made of ABS resin or the like. These arms 30, 34 are spaced apart laterally and extend in the front-rear direction.

[0051] As shown in Figure 4, the front end of the left arm section 30 is connected to the shield support section 14, and the rear end of the left arm section 30 is formed with a hole 60 into which the shafts 52a, 52b of the left attachment section 32 provided on the mounting section 16 are fitted. In addition, the rear end of the left arm section 30 is provided with a protrusion 62 that protrudes radially from the shafts 52a, 52b, which serve as the "rotation shaft." When a circumscribing circle is imagined that is centered on the rotation center of the left arm section 30 and circumscribes the protrusion 62, a portion of this circumscribing circle intersects with the inner surface of the stopper section 54. The right arm section 34 is configured bilaterally symmetrical with respect to the left arm section 30.

[0052] Figure 6 shows the state of the left arm part 30 of the connecting part 18, with Figure 6(A) showing the state when the shield part 12 is in the lowered position P1, Figure 6(B) showing the state when the shield part 12 is in the middle of being moved between the lowered position P1 and the raised position P2, and Figure 6(C) showing the state when the shield part 12 is in the raised position P2. The state of the right arm part 34 shown in Figure 2 is bilaterally symmetrical to the state of the left arm part 30.

[0053] 6(A), when the shield part 12 is in the lowered position P1, the protrusion 62 of the left arm part 30 is positioned above the horizontal line Q passing through the rotation center. When a force acts on the shield part 12 in this state to rotate it upward, the protrusion 62 hits the stopper part 54, thereby suppressing the rotation of the shield part 12. Therefore, it is unlikely that the shield part 12 will be lifted by natural forces such as wind force.

[0054] When the shield part 12 is not needed, such as when eating or drinking, the user M lifts the shield part 12 with his or her hand and rotates it to the raised position P2. As shown in FIG. 6(B), during this rotation process, the protrusion 62 is pressed against the stopper part 54, but the stopper part 54 is elastically deformed outward, allowing the shield part 12 to rotate. During this rotation process, a reaction force is transmitted from the stopper part 54 to the hand of the user M, and the user M can sense the fluctuations in this reaction force to know the state of the shield part 12.

[0055] As shown in Figure 6(C), when the shield part 12 is in the raised position P2, the protrusion 62 of the left arm part 30 is positioned below the horizontal line Q passing through the rotation center. When a force acts on the shield part 12 in this state to rotate it downward, the protrusion 62 hits the stopper part 54, thereby suppressing the rotation of the shield part 12. Therefore, it is unlikely that the shield part 12 will fall due to vibration or the like.

[0056] (Effects of the first embodiment) According to this embodiment, the above configuration can achieve the following effects. That is, as shown in FIG. 2, the plate-shaped shield portion 12 is supported by the shield support portion 14, and the left-right center portion of the shield support portion 14 and the left-right center portion of the attachment portion 16 are connected while being spaced apart from each other, so that the shield portion 12 can be positioned sufficiently away from the face F of the user M (FIG. 1). Furthermore, the left-right center portion of the attachment portion 16 is supported by the nose of the user M at the nose hook portion 24, so that the shield support portion 14 and the shield portion 12 connected to this center portion can be accurately positioned with respect to the nose and mouth of the user M, and there is no need to form the shield portion 12 larger than necessary. Therefore, it is possible to effectively prevent the face F of the user M from becoming hot and stuffy.

[0057] As shown in Figure 6, by rotating the arm portion 30 (34), the shield portion 12 can be moved between a lowered position P1, which covers the nose and mouth of the user M, and an elevated position P2, which moves the shield portion 12 upward and away from the nose and mouth of the user M. When the shield portion 12 is moved to the elevated position P2, a large space is secured in front of the mouth of the user M, allowing the user M to eat and drink while wearing the splash prevention mouth shield 10.

[0058] The shield support part 14 to which the front end of the arm part 30 (34) is connected is provided at the upper end part 12a of the shield part 12, so when the arm part 30 (34) is rotated to move the shield part 12 to the raised position P2 (Figure 6 (C)), the upper end part 12a of the shield part 12 does not come into contact with the face F (Figure 1) of the user M.

[0059] 6(C), when the shield part 12 is in the raised position P2, the protrusion 62 comes into contact with the stopper part 54, thereby preventing the arm part 30 (34) from rotating downward. Therefore, when the user M is eating or drinking, the shield part 12 can be held in the raised position P2.

[0060] As shown in Figure 4, the multiple protrusions 20 of the shield support part 14 and the multiple through holes 22 of the shield part 12 are detachably engaged, so that the shield part 12 can be replaced with another shield part 12 of a different size, and a damaged shield part 12 can be replaced with a new shield part 12.

[0061] By hooking the ear hooks 26, 28 on both the left and right sides shown in Figure 2 over the left and right ears of the user M and hooking the nose hook 24 shown in Figure 2 over the nose of the user M, the attachment part 16 can be easily and stably attached to the face F of the user M.

[0062] As shown in Figure 2, nose pads 24 are supported over a wide area of ​​the nostrils on both sides, providing stable support even for large shield parts 12. Furthermore, even when wearing splash guard mouth shield 10, the nose pads of eyeglasses can be placed against the bridge of the nose, allowing splash guard mouth shield 10 to be used in conjunction with eyeglasses.

[0063] As shown in FIG. 2 , the left and right shield temples 38, 40 are curved downward to form a U-shape. This prevents interference between the shield temples 38, 40 and the temples of the eyeglasses, resulting in a comfortable fit. Furthermore, the U-shaped portions of the left and right shield temples 38, 40 elastically open to deform to fit the size of the user M's head or face. This allows the glasses to accommodate various head or face sizes and ensure a stable fit by sandwiching the head between the nose piece 24 and the ear hooks 26, 28. Furthermore, because the lower portions of the left and right shield temples 38, 40 can be brought into contact with the user M's cheeks, the mounting portion 16 is less likely to move vertically. Therefore, the connecting portion 18, the shield support portion 14, and the shield portion 12 can be easily rotated by the user M's hand. It goes without saying that the lower portions of the left and right shield temples 38, 40 may be spaced apart from the user M's cheeks so as not to come into contact with them. Furthermore, the shield temples 38 and 40 on both the left and right sides may be made of a rigid body whose U-shaped portion does not elastically deform.

[0064] The cylindrical fitting holes 48 (Fig. 3) of the left ear hook portion 26 and the right ear hook portion 28 shown in Fig. 2 are fitted with the cylindrical fitting protrusions 46 (Fig. 3) of the left shield temple 38 and the right shield temple 40, respectively, so that the orientation of the left ear hook portion 26 and the right ear hook portion 28 can be easily adjusted by rotating them.

[0065] The shield support part 14, the attachment part 16 and the connecting part 18 shown in FIG. 2 are formed of a transparent or translucent material, and this, combined with the fact that the shield part 12 is transparent, makes the entire splash prevention mouth shield 10 less noticeable.

[0066] (Variation) It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the present invention. For example, in the above-described embodiment, the shield support portion 14, the mounting portion 16, and the connecting portion 18 are formed of a transparent or translucent material, but at least one of these may be formed of an opaque material.

[0067] As shown in FIG. 6(B), in the above embodiment, the stopper portion 54 for suppressing the rotation of the shield portion 12 is formed in a plate shape, but the stopper portion 54 may also be formed in a rod shape or a protrusion shape.

[0068] 2, in the above embodiment, the shield temples 38, 40 on both the left and right sides are curved downward to form a U-shape, but they may also be formed in a straight line extending in the front-to-rear direction, like the temples of ordinary eyeglasses. Also, the distance between the lower portions of the shield temples 38, 40 may be set to be the same as the distance between the left and right cheeks of the user M (FIG. 1), or may be set to be wider than that.

[0069] 2, in the above embodiment, the left arm portion 30 and the right arm portion 34 of the connecting portion 18 are formed in a rod shape, but they may also be formed in a plate shape. In addition, one of the left arm portion 30 and the right arm portion 34 may be omitted, or at least one other arm portion may be added.

[0070] 2, in the above embodiment, the left ear hook 26 and the right ear hook 28 are used as means for supporting the attachment unit 16 on the left and right ears of the user M (FIG. 1), but these may be replaced with left and right circular elastic strings (not shown) that are looped around the left and right ears, or may be replaced with a band or the like that is looped around the back of the head of the user M (FIG. 1).

[0071] (Second embodiment) Fig. 7 is a perspective view showing a splash prevention mouth shield 64 according to a second embodiment in use. In the splash prevention mouth shield 10 according to the first embodiment shown in Fig. 2, the left ear hook 26 and the right ear hook 28 are hooked over the left and right ears of the user M (Fig. 1), causing interference with the temples of the eyeglasses. To solve this problem, the splash prevention mouth shield 64 shown in Fig. 7 uses a left temple hook 66 instead of the left ear hook 26, and a right temple hook (not shown) instead of the right ear hook 26.

[0072] Figure 8 shows the configuration of the left temple hooking part 66, with Figure 8(A) showing the left side of the left temple hooking part 66 as seen from slightly behind, and Figure 8(B) showing the right side of the left temple hooking part 66 as seen from slightly behind. Although not shown, the right temple hooking part is configured symmetrically with respect to the left temple hooking part 66.

[0073] 8(A) and (B) is a portion that is hooked onto the left temple 68a of the eyeglasses 68 shown in Fig. 7, and is made of an elastic material such as silicone. The left temple hook 66 has an outer wall portion 70 that is arranged along the outer surface of the left temple 68a, an inner wall portion 72 that is arranged along the inner surface of the left temple 68a, and an upper wall portion 74 that connects the upper edge of the outer wall portion 70 and the upper edge of the inner wall portion 72.

[0074] The vertical length of the rear end 70a of the outer wall portion 70 is set to be sufficiently longer than the vertical length of the rear end 72a of the inner wall portion 72, and a cylindrical connecting portion 76 that connects to the connecting portion 56 of the left shield temple 38 is provided at a portion of the rear end 70a of the outer wall portion 70 that is located below the rear end 72a of the inner wall portion 72. A cylindrical mating hole 78 is provided at the front end of the connecting portion 76, into which the mating protrusion 46 provided at the rear end of the left shield temple 38 is mated.

[0075] As shown in Figure 8(B), a space S2 that connects to the space S1 below the upper wall portion 74 is defined between the rear end portion 72a of the inner wall portion 72 and the connecting portion 76. When the left temple hooking portion 66 is hung on the left temple 68a (Figure 7), the left temple 68a is passed through the space S2 and accommodated in the space S1.

[0076] As shown in Figure 7, with the splash prevention mouth shield 64 of the second embodiment, the left temple hook portion 66 and the right temple hook portion (not shown) are hooked onto the left temple 68a and the right temple (not shown) of the glasses 68, and the nose hook portion 24 is hooked onto the nose of the user M, so that the attachment portion 16 can be easily and stably attached to the face F of the user M.

[0077] Furthermore, by preparing the left and right temple hooks 66 and 28 (not shown) and the left and right ear hooks 26 and 28 in advance, these can be selectively attached to the rear ends of the left and right shield temples 38, 40. In other words, by using the left and right ear hooks 26 and 28, the mounting unit 16 can be easily and stably attached to the face F of a user M who does not wear eyeglasses, and by using the left and right temple hooks 66 and 28 (not shown), the mounting unit 16 can be easily and stably attached to the face F of a user M who wears eyeglasses 68 (FIG. 7).
