Japanese Unexamined Patent Publication No. 2019-85669

The sun visor type face shield 60 on the market can be used even if the wearer wears glasses or a mask, but the head band 62 is provided and the price is high, and there is a risk of infection with a virus or the like at a medical institution or the like. Since there is a high possibility that a virus has adhered to the surface of the face shield 60 used when performing a certain task, it is replaced with a new one for each patient and discarded, which consumes a large amount of the face shield 60, which is cost effective. There was a problem that it was too expensive.

The face shield of Patent Document 1 can be used even when wearing glasses or a mask, but it is a type that is used by being attached to a helmet, and is expensive because the face cover can be raised and lowered. Since medical institutions do not use helmets, there is a problem that the face shield of Patent Document 1 cannot be used.

The present invention was devised in view of these problems, and the object is to provide a face shield that can be firmly fixed by a mask or by a mask and eyeglasses, and can be replaced with a new one every day at a low cost. To do.

In the present invention, the front view means the front view when the wearer wears the sheet-shaped face shield. Therefore, the description of the configuration of the face shield will be described in the state where the face shield is upright as in the used state even in the non-use state.

The face shield according to claim 1 is a face shield made of a transparent sheet-shaped face cover having a size of covering the face, and when the glasses are attached to the face cover in a front view. With flaps formed by substantially U-shaped temple cuts connected to the center side in the left-right direction so that the temples can be inserted into the range of the face cover corresponding to the front ends of the left and right temples of the glasses. An opening is provided, and when the mask is attached to the face shield, the lower side is connected in the vertical direction to the range of the face cover corresponding to each of the left and right ends of the mask body of the mask in the vertical direction. A substantially U-shaped cut for a string having different lengths is formed, and the upper string of the mask can be inserted into the vertical cut on the side end side in the left-right direction of the face cover. The length is slightly longer than the diameter of the face cover, and the vertical cut on the center side in the left-right direction of the face cover is extended to the edge of the lower end of the face cover so that the string under the mask can be inserted. It is characterized by having a length.

The face shield according to claim 2 is the left and right side of the eyeglasses in order to stabilize the posture of the face shield with respect to the eyeglasses when the temple is inserted into the flapped opening in the first aspect. The feature is that the position of the flapped opening in the face cover and the size of the flapped opening are preset in accordance with the length between the temples and the thickness and width of the temple. To do.

The face shield according to claim 3 has the size and position of the flapped opening in claims 1 or 2, for general frame eyeglasses, frame extra-thick eyeglasses, and medical goggles. It is characterized by setting three places.

The face shield according to claim 4, in any one of claims 1 to 3, is an extension path to the edge of the lower end portion of the face cover, which is a vertical cut of the center side T in the left-right direction of the face cover. The first form in which the form is extended straight down to near the lower end of the face cover, the direction is changed toward the diagonal end near the lower end, and the face cover is extended straight down to the peripheral edge, or the form is extended straight down to near the lower end of the face cover. The second form is characterized in that the lower end portion of the portion of the face cover on the side end side from the extended cut is formed in an arc shape.

The face shield 1 according to claim 1 is composed of only one transparent sheet-shaped face cover 2, and only a cut is provided for processing. Therefore, the configuration is extremely simple and the face shield 1 can be manufactured at an extremely low cost. In order to prevent infection, it has the effect of reducing costs even if it is thrown away after daily use.

Even if only the mask 20 is worn, or even if the mask 20 and the glasses 10 are worn, the face shield 1 can be firmly fixed to the face 51.

Further, an opening with a flap is formed by the substantially U-shaped temple cut 3, and the formed quadrangular flap piece 4 can be opened and closed with a line connecting the upper and lower edges of the front end edge of the temple cut 3 as an axis. Therefore, when the flap piece 4 is pushed out by the temple 11 of the eyeglasses 10 from the inside to the outside of the face cover 2, the flap piece 4 becomes like a lid that opens and closes with the front side as the axis, and the flap piece Once the 4 is bent, a reaction force that tries to return to the original state is generated. Therefore, since the flap piece 4 has an urging force toward the temple 11 side, the flap piece 4 is a splash flying from a third party. It protects the H from entering the inside of the face cover 2, and can ensure the safety of the wearer 50 against infection.

Further, since the string 21 on the upper side of the mask can be sandwiched by the cut 5a on the side end side F in the vertical direction of the substantially U-shaped string cut 5, the positional relationship between the mask 20 and the face shield 1 is fixed. It has the effect of being able to be transformed.

Further, by extending the cut 5b on the central side T in the vertical direction of the substantially U-shaped string cut 5 to the lower end of the face cover 2, the face cover 2 can be separated at the cut 5b as a boundary. Therefore, the upper string 21 and the lower string 22 of the mask can be easily displaced with respect to the face cover 2.

Further, the upper string 21 of the mask 20 is extended from the cut 5a on the side end side F of the substantially U-shaped string cut 5 in the vertical direction, and the center side of the substantially U-shaped string cut 5 in the vertical direction. Since the lower string 22 of the mask 20 is taken out from the cut 5b of T to the front side of the face cover 2, the strings 21 and 22 attached to the ear at the time of use firmly hold the face cover 2 in the direction of the face 51. By pressing it, the face shield 1 can be firmly fixed to the face 51.

According to the invention according to claim 2 or 3, the size of the eyeglasses 10 is roughly divided into three types: general frame eyeglasses, extra-thick frame eyeglasses, and medical goggles. When the face shield 1 is attached to the eyeglasses 10, the face shield 1 can be fixed so as not to shake when the wearer faces downward or upward, and the face shield with respect to the eyeglasses 10 can be fixed. The posture of 1 can be stabilized.

Further, if the position of the flapped opening for inserting the temple 11 in the face cover 2 and the size of the flapped opening are only one for eyeglasses of a general frame. Since a general frame is thin and small, there is a problem that neither the thick and slightly large frame extra-thick eyeglasses nor the thick and large temple 11 of the medical goggles can be inserted. Since the face shield 1 of the present invention is provided with the flapped opening corresponding to each eyeglass, one face shield 1 can be fixed to a plurality of types of eyeglasses.

The invention according to claim 4 shows the case where the cut 5b on the vertical center side T of the substantially U-shaped string cut 5 is extended straight to the lower end, as shown in FIG. 10 (c). As shown, the outer shape of the lower end has an acute-angled shape (arrow view c), which may damage the face. However, in the present invention, the cut 5b is made as shown in FIG. 10 (a). The first form in which the face cover 2 is extended straight downward to near the lower end, the direction is changed to the diagonal end side F near the lower end, and the face cover 2 is provided as it is up to the peripheral edge, or as shown in FIG. 10B, the face cover 2 Since the outer shape of the lower end is an arc shape (arrow b), the tip shape is not an acute angle shape (arrow c) but an obtuse angle shape (arrow a) or an arc shape (arrow b), so that the face 51 It has a safety effect of not scratching.

It is a front view of the face shield of this invention. It is explanatory drawing of the use state which attached the face shield made of the transparent face cover of this invention to eyeglasses and a mask. For the purpose of explaining the usage state of the present invention in FIG. 2, in order to make it easier to understand the positional relationship between the eyeglasses and the mask, the face cover of the present invention is attached to the eyeglasses and the mask assuming that the face cover is opaque. It is explanatory drawing of the use state of the face shield. It is explanatory drawing of the positional relationship between the face shield and the temple at the height of the temple of the eyeglass of the face shield of this invention. It is an enlarged explanatory view of the part A in FIG. It is explanatory drawing of the positional relationship between a face shield and a mask in the range of the face shield corresponding to each of both ends in the left-right direction of a mask body. It is a D arrow view in FIG. It is an enlarged explanatory view of the B1 part in FIG. 6 or the B2 part in FIG. 7, which is a part having the same configuration. FIG. 7 is an enlarged view of part C in FIG. An explanatory view of the edge shape of the lower end of the face cover, (a) is an explanatory view of the first form when the tip shape is an acute angle, and (b) an explanatory view of the second form when the tip shape is an arc shape. (C) is an explanatory view when the tip shape is an acute angle. It is a perspective view of a general face shield in circulation.

The face shield 1 of the present invention is used by a person who has to work face-to-face with a third party such as a dentist or a person engaged in a medical institution such as internal medicine, and is used in a work environment where it must be thrown away to prevent infection. A suitable face shield 1. As shown in FIG. 2 or 3, the face shield 1 of the present invention can be used by the wearer of the mask 20 or the wearer of the mask 20 and the glasses 10.

As shown in FIG. 1, the face shield 1 of the present invention is a face shield 1 composed of a transparent sheet-shaped face cover 2 having a size of covering a face, and is a face on the face cover 2 when viewed from the front. When the glasses 10 are attached to the shield 1, the center side is connected in the left-right direction so that the temples 11 can be inserted into the range of the face cover 2 corresponding to the front ends of the left and right temples 11 of the glasses 10. An opening with a flap formed by a substantially U-shaped temple cut 3 is provided, and when the mask 20 is attached to the face shield 1, both ends of the mask body 23 of the mask 20 in the left-right direction are provided. In the range of the corresponding face cover 2, a substantially U-shaped string cut 5 having two vertical cuts having different lengths, which are connected to the lower side in the vertical direction, is formed, and in the horizontal direction of the face cover 2. The vertical cut 5a of the side end side F has a length slightly longer than the diameter of the string 21 so that the upper string 21 of the mask 20 can be inserted, and the vertical cut 5a of the face cover 2 is vertically above and below the center side T in the left-right direction of the face cover 2. The cut 5b in the direction has a length extending to the edge of the lower end of the face cover 2 so that the lower string 22 of the mask 20 can be inserted.

As shown in FIGS. 1 to 3, the face cover 2 is in the form of a transparent sheet having a size covering the face. The material of the face cover 2 may be a transparent, shape-retainable, bendable and deformable sheet-like material, and examples thereof include polypropylene (PP), polyvinyl chloride, and polyethylene terephthalate (PET). The thickness of the face cover 2 may be any thickness as long as it can retain its shape and can be bent and deformed. For example, the thickness is preferably 0.1 to 0.4 mm, more preferably 0.15 to 0.2 mm.

The face cover 2 preferably has a size slightly larger than the size of the face 51 of the wearer 50. As a result, it is possible to prevent the splash H from the facing third party from hitting the wearer 50. Further, in order to prevent the face cover 2 from being cut even if it hits the face 51, the outer shape is preferably a substantially elliptical shape having no protrusion on the peripheral edge.

First, a configuration for attaching the spectacles 10 to the face shield 1 will be described. As shown in FIGS. 1 to 5, the center side is connected in the left-right direction in which the temple 11 can be inserted into the range of the face cover 2 corresponding to the front ends of the left and right temples 11 of the spectacles 10. An opening with a flap formed by a substantially U-shaped temple cut 3 is provided. The flapped opening includes a flap piece 4.

In order to stabilize the posture of the face shield 1 with respect to the eyeglasses 10 when the temple 11 is inserted into the flapped opening, for example, when the wearer 50 is turned downward from the front, the face The position of the flapped opening in the face cover 2 corresponding to the length between the left and right temples 11 of the eyeglasses 10 and the thickness and width of the temples 11 so as not to cause the shield 1 to swing loosely. , And the size of the flapped opening is preset.

Therefore, the size and position of the flapped opening are set at three locations: for general frame eyeglasses, for frame extra-thick eyeglasses, and for medical goggles.

A substantially U-shaped temple cut 3c is provided for general frame eyeglasses with a narrow cut near the center, and a wide cut for frame extra-thick eyeglasses is provided on the side edge side F slightly from the temple cut 3c. A substantially U-shaped temple cut 3b formed in the above is provided, and a substantially U-shaped temple cut 3a is provided in which a wide cut for medical goggles is formed on the side end side F from the temple cut 3b.

As a result, the center of gravity of the face shield 1 is the opening with the flap, regardless of whether the wearer 50 faces downward or upward, even in general frame eyeglasses, extra-thick frame eyeglasses, or medical goggles. It is possible to prevent the face shield 1 from swinging steadily because it does not move forward more than the portion. Further, general frame eyeglasses, extra-thick frame eyeglasses, or medical goggles can be attached to the face shield 1.

Further, as shown in FIG. 1, a line connecting the upper and lower central sides of the substantially U-shaped temple cut 3 in the horizontal direction by the substantially U-shaped temple cut 3 connected to the center side. A flap piece 4 that can be opened and closed in the left-right direction is formed around the axis. As shown in FIG. 5, the flap piece 4 has an urging force P1 in the closing direction. Therefore, when the flap piece 4 is pushed outward by the temple 11 of the spectacles 10 to open, the temple 11 is opened. Since the flap piece 4 tries to close while being sandwiched, the flap piece 4 can guard the splash H from the person facing the face so as not to enter the inside of the face shield 1.

Next, a configuration for attaching the mask 20 to the face shield 1 will be described. As shown in FIGS. 1 and 6 to 9, when the mask 20 is attached to the face shield 1, the range of the face cover 2 corresponding to both ends of the mask body 23 in the left-right direction of the mask 20 A substantially U-shaped string cut 5 having different lengths of two vertical cuts connected to the lower side in the vertical direction is formed, and a vertical cut 5a of the side end side F in the left-right direction of the face cover 2 is formed. Is a length slightly longer than the diameter of the string 21 so that the upper string 21 of the mask 20 can be inserted, and the vertical cut 5b of the center side T in the left-right direction of the face cover 2 is below the mask 20. The length is such that the side string 22 can be inserted and extended to the edge of the lower end of the face cover 2. The cut 5a and the cut 5b are components of the string cut 5.

Further, as shown in FIG. 8, the upper string 21 of the mask 20 is inserted between the face covers 2 which are the cuts 5a on the side end side F and one of which is the flap piece 6. Since the length of the cut 5a is only slightly longer than the diameter of the string 21, the flap piece 6 has an urging force P3 that tries to return to the original state even if it is bent once in the opening direction. The face cover 2 including 6 can firmly hold the upper string 21 of the mask 20. Then, as shown in FIGS. 3, 7, and 8, the upper string 21 of the mask 20 is taken out from the cut 5a to the front side of the face shield 1.

Further, as shown in FIG. 8, since the flap piece 6 is provided as a lid in the cut 5a in which the upper string 21 of the mask 20 is inserted, the flap piece 6 is a lid, so that the wearer 50 is faced with a splash from a third party. It is possible to prevent H from invading the inside of the face shield 1.

Next, as shown in FIG. 9, the lower string 22 of the mask 20 is inserted into the cut 5b of the central side T, and as shown in FIGS. 3, 7, and 9, under the mask 20. The side string 22 is taken out from the cut 5b to the front side of the face shield 1.

Further, as shown in FIG. 8, the upper string 21 of the mask 20 taken out on the front side of the face shield 1 presses the face shield 1 against the face 51 side by the elastic force P2 of the upper string 21, and is under the mask 20. As shown in FIG. 9, the side string 22 presses the face shield 1 against the face 51 side by the elastic force P4 of the lower string 22 of the mask. As a result, the face shield 1 can be fixed to the face 51 by the mask 20.

As a result, the positional relationship between the mask 20 and the face shield 1 does not shift even when the face shield wearer 50 takes various postures at work.

Next, as shown in FIG. 10A, the form of the extension path to the edge of the lower end portion of the face cover 2 of the vertical cut 5b of the central side T in the left-right direction of the face cover 2 is shown by the face. The first form of extending straight downward to near the lower end of the cover 2, changing the direction to the diagonal end direction F near the lower end and extending to the peripheral edge as it is, or the lower end of the face cover 2 as shown in FIG. 10 (b). This is the second form in which the face cover 2 is extended straight down to a close position, and the lower end portion of the portion of the face cover 2 on the side end side F from the extended cut 5b is formed in an arc shape.

The reason why the cut 5b on the center side T is extended to the lower end of the face cover 2 is that when the face cover 2 is made separable at the cut 5b and the mask 20 is attached to the face shield 1. When the lower string 22 of the mask 20 is easily inserted into the cut 5b, the position of the mask 20 is easily adjusted with respect to the face shield 1, and the mask 2 attached to the face shield 1 is worn. This is because the face shield 1 is pressed and fixed from the outside by the strings 21 and 22 of the mask 20.

Further, as shown in FIG. 10 (c), the cut 5b of the face cover 2 is not straightened in the vertical direction, but as shown in FIG. 10 (b), the direction is changed from slightly above the lower end to downward and to the side end side F. By doing so, or by forming the lower end portion in an arc shape as shown in FIG. 10 (c), the face 51 of the wearer 50 can be prevented from being scratched.

From the above, the face shield 1 of the present invention can be firmly fixed to eyeglasses 10 or masks 20 of different sizes while having a simple form consisting of one sheet-shaped face cover 2 and being inexpensive. The face shield 1 is not wobbly even when the wearer is turned downward, and the effect is that the splash H from a third party is not invaded.
