  Conventionally, in the fields of medical care and nursing care, face protection provided with a shielding member for protecting all or part of the face from infection sources such as blood, secretions, saliva and vomiting and liquids such as water and chemicals. Ingredients are known. As this type of face protection device, for example, a nose pad and a temple member are fixed to a lens frame that holds a lens as a shield member, and the glasses member is used by placing the nose pad on the nose and putting the temple member on the ear It has been known. A headband comprising a goggle part (shield part) provided in front of the user's eyes, a holding part for holding the shield part, and a mounting part connected to the holding part and attached to the head. The type goggles are also known (see, for example, Patent Documents 1 and 2).

JP 2007-089748 A JP 2009-031473 A

  However, when the wearer wears spectacles, the spectacle-type face protector is difficult to use together because the nose pad and the temple member interfere with each member of the spectacles. In addition, since there are individual differences in the position of the nose and ears, the size of the head, etc., it is difficult to ensure the stability when worn.

  In addition, even with the headband type goggles of Patent Documents 1 and 2, it is difficult to ensure the stability at the time of wearing regardless of individual differences in the size, shape, hair amount, etc. of the head. There was a problem of misalignment in the direction. If it is forcibly fixed to the head, the feeling of fitting will be extremely poor, causing discomfort and pain, which may hinder the work performed using the face protector. Such a problem is not limited to the face protectors used in the medical and care fields, but also exists in the face protectors used in other fields.

  In view of such circumstances, the present invention provides a face protector and a face protector frame that can reliably ensure wearing stability and achieve good fit comfort regardless of individual differences such as the size of the head. The purpose is to provide.

An aspect of the present invention that solves the above problems includes a main body frame that is worn on the head, a shield frame that is disposed outside the main body frame and holds a shield member that protects all or part of the face of the wearer. The main body frame includes a bridge arm that extends from the front to the head to both occipital heads, a first support that is provided at both ends of the bridge arm and supports the back, and the bridge arm. A pair of head arms that are branched from a portion corresponding to the side of the head to the front of the head and are arranged inside the bridge arm, and a head that is provided at the tip of the head arm and supports the front of the head. A first pressing force adjustment that adjusts the pressing force to the occipital region of the first support portion, the portion corresponding to the anterior portion of the bridge arm being disposed away from the anterior head portion. Becomes part, the head arm, has a second pressing force adjusting unit that adjusts a pressing force to the forehead of the second supporting portion, the area of the second supporting portion of the first support portion The face protector frame is characterized by being larger than the area .

According to this aspect, two points of the back of the head are supported by the first support portions provided at both ends of the bridge arm, and two points of the front of the head are supported by the second support portions provided at the tip portions of the head arm. Since the head is supported, that is, the head is supported by a total of four points, front, rear, left, and right, the mounting stability can be ensured regardless of individual differences such as the size of the head. In addition, when wearing, simply placing the head roughly between the bridge arms that have been spread, and using the elastic deformation force that the bridge arm and head arm will return to the initial state if the spread force is released. to the frame for face protection can be well supported automatically stability to the head. In addition, since the pressing force to the occipital region and the frontal region is adjusted by the first pressing force adjusting unit of the bridge arm and the second pressing force adjusting unit of the head arm, it is possible to realize a good fit. The area of the second support part is larger than the area of the first support part. According to this, the supporting force to the frontal head of the face protection device can be increased. Since the shield frame and the shield are provided, the weight toward the forehead tends to increase. However, the weight can be dispersed by the second support portion having a large area, and a good fit can be surely realized. Further, when the shield frame is configured to be able to rotate in the vertical direction with respect to the main body frame by increasing the support force of the face protection device to the frontal head, the shield frame can be easily rotated. Further, it is possible to prevent the face protector from being displaced in the vertical and horizontal directions due to the turning operation.

  The angle formed by the plane formed by the bridge arm and the plane formed by the head arm is preferably in the range of 0 to 30 degrees. According to this, it becomes easy to manufacture said main body frame with a metal mold | die. Therefore, it is possible to easily provide a frame for a face protection device that can ensure the mounting stability and can realize a good fit.

  Moreover, it is preferable that the part corresponding to the temporal region of the bridge arm has higher rigidity than the first pressing force adjustment unit and the second pressing force adjustment unit. According to this, the first pressing force adjusting part of the bridge arm and the second pressing force adjusting part of the head arm are preferentially elastically deformed because the rigidity of the portion corresponding to the temporal region of the bridge arm is high. . Therefore, further mounting stability to the head can be surely ensured, and an extremely good fit can be realized. In addition, the rigidity of the portion corresponding to the side head of the bridge arm (the branch portion of the head arm) is ensured, and durability against long-term use and repeated use can be improved.

  The shield frame is preferably detachable from the main body frame. According to this, it is possible to provide a frame for a face protection device that can reliably ensure the mounting stability and can realize a good fit, and can easily repair and replace each frame.

  Further, it is preferable that the main body frame and each of both end sides of the shield frame are connected by a predetermined shaft member, and the shield frame is configured to be rotatable around the shaft member. According to this, the shield frame can be rotated in the vertical direction in a state where the face protector frame is mounted on the head. Therefore, it is possible to provide a frame for a face protection device that can reliably ensure wearing stability and can realize a good fit, and can easily realize a use mode according to a use and an external environment.

  According to another aspect of the present invention for solving the above-described problems, the face protection device frame according to any one of the above and the face protection device frame can be attached to and detached from the face protection device to protect all or part of the face of the wearer. And a shield member. According to this aspect, since the face protector frame according to any one of the above is provided, it is possible to provide a face protector that can reliably secure the wearing stability and can achieve a good fit.

  According to the face protector and the face protector frame of the present invention, it is possible to reliably secure the wearing stability regardless of individual differences such as the size of the head and to achieve a good fit.

The figure explaining adjustment of the pressing force at the time of wearing of the face protector of this embodiment. The figure which shows the face protector of a comparative example. The figure explaining the example of composition of the face protector of other this embodiment.

  FIG. 1 is a perspective view illustrating a configuration example of a face protector according to an embodiment of the present invention, and FIGS. 2A to 2C are diagrams illustrating a configuration example of each frame and the like in FIG.

  As shown in the figure, the face protector 1 according to this embodiment is detachable from the face protector frame and the face protector frame, and shields all or part of the face from infectious droplets and chemicals. S. Of these, the face protector frame includes a main body frame 10 attached to the head and a shield frame 20 that is disposed outside the main body frame 10 and holds the shield S described above.

  The main body frame 10 includes a bridge arm 11 that extends from the front to the head to both occipital heads, a first support 11 a that is provided at both ends of the bridge arm 11 and supports the back, and a side of the bridge arm 11. Branching from the portion 11b corresponding to the head portion in the frontal head direction, a pair of head arms 12 disposed inside the bridge arm 11, and a second portion provided at the tip of the head arm 12 and supporting the front head portion. And a support portion 12a. The bridge arm 11 and the head arm 12 have a curved shape corresponding to the head and are configured to be elastically deformable in the opposite direction of the head arm 12. It is possible to support the part.

  Attachment portions 13 to which the shield frame 20 is attached are respectively provided on the left and right sides of the main body frame 10. Here, the attachment portion 13 is formed in the vicinity of the portion 11 b corresponding to the temporal region of the bridge arm 11. The mounting portion 13 is, for example, provided integrally with the main body frame 10 on one side of the surface formed by the main body frame 10, and a plurality of predetermined engagement holes 14 are formed in series (here, three each on the left and right sides). It is. By selecting one of the above-mentioned engagement holes 14 and pivotally supporting engagement shafts 21 provided so as to face each other at both ends of the shield frame 20, the distance and angle with respect to the main body frame 10 can be adjusted. The frame 20 can be attached.

In particular, in the present embodiment, a protrusion 21 a is integrally provided at the base of the engagement shaft 21 of the shield frame 20, and the protrusion 21 a is fitted to the edge of the engagement hole 14 of the main body frame 10. A possible fitting groove 14 a and a loose fitting groove 14 b formed wider than the fitting groove 14 a in the rotational direction of the shield frame 20 are provided. Thus, the shield frame 20 is rotated at a predetermined angle θ ₁ with respect to the main body frame 10 with the engagement shaft 21 as a fulcrum within a range where the protrusion 21a of the engagement shaft 21 is regulated by the loose fitting groove 14b. Can do. Then, by further rotating the shield frame 20 beyond the loose fit groove 14b, so that the protrusion 21a of the engagement shaft 21 is fitted at a predetermined angle theta ₂ to the fitting groove 14a, i.e., the body frame The shield frame 20 can be held at a predetermined angle θ ₂ with respect to 10.

  As described above, the shield frame 20 can be rotated in the vertical direction around the engaging shaft 21 and can be held at a predetermined angle, so that the face protector frame is mounted on the head. Thus, the angle of the shield S in the vertical direction can be freely set. For example, while the shield S protects all or part of the face from infectious droplets or chemicals, a rotation operation or an angle holding operation is performed so that the shield frame 20 is flipped up with respect to the main body frame 10 as necessary. Thus, the face protection by the shield S can be temporarily released without removing the shield S one by one. In this way, it is possible to provide a face protector frame that can easily realize a use mode according to the application and the external environment.

  In this embodiment, by selecting the engagement hole 14 into which the engagement shaft 21 is inserted as described above, the distance of the shield frame 20 with respect to the main body frame 10 can also be adjusted. Even when a mask or the like is further used in combination, a sufficient distance can be secured so that the shield S attached to the shield frame 20 does not interfere with the shield S as necessary.

  However, the connection mode between the main body frame 10 and the shield frame 20 is as long as the shield frame 20 can be arranged outside the main body frame 10 so that the shield S can cover all or part of the face in use. However, the present invention is not limited to the above example. For example, contrary to the above example, the main body frame 10 may be provided with an engagement shaft, and the shield frame 20 may be provided with an engagement hole. If the shield frame 20 can be attached to and detached from the main body frame 10, it becomes easy to repair and replace each frame, but it is not essential to be able to adjust the distance and angle of the shield frame 20 with respect to the main body frame 10. In addition, each frame may be integrally formed.

  When the main body frame 10 and the shield frame 20 are connected by a predetermined shaft member, a sliding agent such as silicone oil is applied to the shaft support portion of the shaft member from the viewpoint of preventing damage and wear due to stress concentration of the shaft member. Alternatively, a reinforcing member such as a washer may be provided on the shaft support portion. It is also possible to make the constituent materials of the shaft member and the member to be a bearing portion different. As an example, in this embodiment, the constituent material of the engagement shaft 21 of the shield frame 20 is used as the constituent material of the body frame 10. A material that can achieve higher elasticity than the engagement hole 14 is selected.

  As a constituent material of the main body frame 10 and the shield frame 20, polypropylene, polyethylene, vinyl chloride, acrylic resin, nylon resin, epoxy resin, polyacetal, polycarbonate, or the like is used alone or in combination of two or more. be able to. In this embodiment, polypropylene is used. According to this, in addition to physical durability and elasticity, a frame for a face protection device excellent in heat resistance and chemical resistance that can withstand boiling disinfection and alcohol disinfection is obtained. .

The shield frame 20 has a curved shape corresponding to the forehead of the wearer, and holding portions 22 for holding the shield S are provided on both ends. For example, the holding portion 22 has a clip member 24 rotatably supported on the outside of the shield frame 20 by a shaft member 23 provided in a direction crossing the extending direction of the shield frame 20, and the shaft member 23 as a fulcrum. And an urging unit that urges the clip member 24 so as to close the distal end portion 24a thereof. Use in the present embodiment, the region R _krp facing the shielding frame 20 at the tip portion 24a of the clip member 24, those engaging claws holes O _pn formed in the shield S is engaged is formed It was.

According to this, by resisting the urging force that closes the distal end portion 24 a of the clip member 24, the clip member 24 is rotated about the shaft member 23 as a fulcrum, and the locking claw can be separated from the shield frame 20. A so-called binder clip mechanism can be realized. Such a mechanism makes it easy to attach and detach the shield S, so that it is possible to reduce the labor and time required for mounting, and the shield S is dropped by the pressing of the rear end portion 24b of the clip member 24 and is picked by hand. It can be disposed of quickly without any problems. Moreover, since the through holes _Opn formed in the shield S are locked by the locking claws of the clip member 24, the shield S can be stably held even at a total of two points on both ends of the shield frame 20, and mounted. It is also possible to prevent the shield S from being distorted.

When the configuration of the holding portion 22 described above is employed, the shield S having a through hole _Opn and a notch _Cout formed at both upper ends can be used. According to this, the holding portion 22 along a notch C _out by the guide, will be able to more easily mounted so as to slide the shield S between the holding portion 22 and the shield frame 20, moreover fitted after, it is possible to regulate the unintentional rotation of the vertical shield S holder 22 with respect to notch C _out becomes a stopper to hold the shield S very stable.

  The shield S can be imparted with antifogging properties using, for example, cellulose triacetate having a relatively large number of hydrophilic groups. That is, the shield S having not only transparency and flexibility but also anti-fogging property is obtained by cellulose triacetate whose surface is modified by alkali treatment. However, the constituent material of the shield S is not limited to the above example, and polyethylene terephthalate, polypropylene, or the like may be used. Further, from the viewpoint of further improving the antifogging property of the shield S, an antifogging agent is added to the constituent material of the shield S or an antifogging agent is applied to the surface of the shield S. It is preferable to further perform a fogging treatment. According to this, the anti-fogging property of the shield S can be secured not only for the user's breathing during normal use but also for a sudden change in the external environment.

  Here, configuration examples and functions related to the main body frame 10 will be described with reference to FIGS. FIG. 3 is a diagram for explaining the pressing force adjusting unit of the bridge arm in the main body frame, and FIG. 4 is a diagram for explaining the adjustment of the pressing force by the pressing force adjusting unit.

  In the main body frame 10, a pair of head arms 12 are arranged so as to branch from the portion 11 b corresponding to the side head of the bridge arm 11 to the inner side in the frontal head direction as described above. When the face protector 1 is worn, the forehead is supported by the head arm 12 so as to be separated from the outer bridge arm 11 by a predetermined distance, and between the forehead and the bridge arm 11. A predetermined first space R1 is formed. The first space R1 secures a bending space of the bridge arm 11, that is, a pressing force adjusting space to the back of the first support portion 11a.

  Thus, the portion corresponding to the frontal portion of the bridge arm 11 is a first pressing force adjusting unit 15 that adjusts the pressing force to the backside of the first support portion 11a. When the space between the bridge arms 11 is expanded from the initial state (FIG. 3A), the first pressing force adjusting unit 15 is bent so that the first space R1 becomes large, and at this time, the elastic deformation force that tries to return to the initial state. Acts in the direction opposite to the first support portion 11a (arrow in FIG. 3B). The elastic deformation force acting in the opposite direction of the first support portion 11a becomes the pressing force to the back of the head when the face protector 1 is worn.

  On the other hand, the head arm 12 is branched inwardly from the bridge arm 11 as described above, and is branched so as to be disposed inward by a predetermined distance from the bridge arm 11. A predetermined second space R2 is formed between the two. The second space R2 secures a bending space of the head arm 12, that is, a second pressing force adjustment space for adjusting the pressing force to the frontal portion of the second support portion 12a.

  Thus, the head arm 12 serves as the second pressing force adjustment unit 16 that adjusts the pressing force to the frontal portion of the second support portion 12a. When the space between the head arms 12 is expanded from the initial state (FIG. 3A), the second pressing force adjusting unit 16 bends so that the second space R2 becomes small, and at this time, an elastic deformation force that attempts to return to the initial state. Acts in the direction opposite to the second support portion 12a (arrow in FIG. 3C). The elastic deformation force acting in the opposite direction of the second support portion 12a becomes the pressing force to the frontal region when the face protector 1 is worn.

  According to the face protector frame as described above, two points on the occipital region are supported by the first support portion 11a, and two points on the frontal portion are supported by the second support portion 12a. The head can be supported by a total of four points, front, rear, left and right. The second pressing force adjusting unit 16 as the head arm 12 bends independently of the first pressing force adjusting unit 15 of the bridge arm 11, and the pair of second pressing force adjusting units 16 are also independent of each other. Therefore, the mounting stability can be reliably ensured regardless of individual differences such as the size of the head.

  In addition, the elastic deformation force that the bridge arm 11 and the head arm 12 return to the initial state by releasing the pushing force simply by positioning the head roughly between the bridge arms 11 pushed and spread at the time of wearing. Can be used to automatically support the face protector frame on the head. In addition, since the pressing force to the occipital region and the forehead region is adjusted by the first pressing force adjusting unit 15 of the bridge arm 11 and the second pressing force adjusting unit 16 of the head arm 12, good fitting comfort can also be realized.

  For example, when the face protector 1 is mounted (FIG. 4A), the second pressing force adjustment unit 16 bends into the second space R2, and the second support portion 12a of the head arm 12 via a predetermined facing distance LF1. By this, the forehead is stably received. Since the second pressing force adjusting unit 16 is bent into the second space R2, the bending of the bridge arm 11 by the forehead is suppressed, and the opposing distance LB1 of the first support portion 11a can be prevented from being excessively separated. The support of the occipital region by the first support portion 11a is not weakened, and the support of the occipital region by the first support portion 11a is not weakened.

  When the wearer's head is relatively large (FIG. 4 (b)), the second pressing force adjustment unit 16 is greatly bent into the second space R2, and the head arm 12 passes through a predetermined facing distance LF2. The frontal head is stably received by the second support portion 12a (LF2> LF1). Since the second pressing force adjusting unit 16 is largely bent into the second space R2, the opposing distance LB2 of the first support portion 11a can be prevented from being excessively separated, and the back of the head supported by the first support portion 11a is weakened. Disappears.

  When the head is relatively small (FIG. 4C), the second pressing force adjusting unit 16 is less bent into the second space R2, but is moved forward by the second support portion 12a of the head arm 12. The head is stably received. Since the head is small, the facing distance LB3 of the first support part 11a is not excessively separated, and the back of the head is stably received by the first support part 11a (LB3 <LB1).

  Thus, according to the face protector frame, the frontal head can be stably supported regardless of individual differences such as the size, shape, and hair volume of the head, and the first support portions 11a can be Since it is not excessively separated from the back of the head and the pressing force to the first support portion 11a to the back of the head is not weakened, the mounting stability can be ensured reliably. Moreover, a good fit can be achieved. Since the face protector 1 extends from the front to the head to the occipital sides of both sides and is supported by the head, the face protector 1 can be used together without interfering with each member such as a nose pad or a temple member of the glasses. It is.

  The area of the second support part 12a is configured to be larger than the area of the first support part 11a. Since the shield frame 20 and the shield S are provided, the weight on the frontal head side tends to increase, but the weight can be dispersed by the second support portion 12a having a large area, and a good fit can be ensured. realizable. Further, since the supporting force of the face protector on the frontal portion is increased, the shield frame 20 can be easily turned, and the face protector 1 is displaced vertically and horizontally due to the turning operation. Can also be prevented.

  Further, the portion 11 b corresponding to the side head of the bridge arm 11 is configured to have higher rigidity than the first pressing force adjustment unit 15 and the second pressing force adjustment unit 16. According to this, the first pressing force adjustment unit 15 of the bridge arm 11 and the second pressing force adjustment unit 16 of the head arm 12 have priority because the portion 11b corresponding to the side head of the bridge arm 11 has high rigidity. It becomes elastically deformed. Therefore, further mounting stability to the head can be surely ensured, and an extremely good fit can be realized. In addition, the rigidity of the portion 11b (the branch portion of the head arm) corresponding to the side head of the bridge arm is ensured, and durability against long-term use and repeated use can be improved.

  The angle formed by the plane formed by the bridge arm 11 and the plane formed by the head arm 12 is configured to be in the range of 0 to 30 degrees. According to this, it becomes easy to manufacture said main body frame with a metal mold | die. In addition, the angle | corner which said is formed is not limited to the said example, For example, it may exist in the range of 30-90 degree | times.

  The usage method of the face protector 1 demonstrated above is as follows. That is, the gap between the bridge arms 11 is pushed and the head is positioned between the bridge arms 11 and then the pushing force is released. Accordingly, the bridge arm 11 and the head arm 12 are automatically moved to the head by using the elastic deformation force that the bridge arm 11 and the head arm 12 return to the initial state without requiring the exact positioning of the head with respect to the face protection frame. Can be installed quickly with good stability. Therefore, the frame for the face protection device can be quickly and easily attached to the head by a simple operation, and even when another person wears the face protection device against the wearing target, it is suitable for the head. It can be quickly and stably mounted on the position. Since the pressing force to the occipital region and the frontal region is adjusted by the first pressing force adjusting unit 15 of the bridge arm 11 and the second pressing force adjusting unit 16 of the head arm 12, good fitting comfort can also be realized.

  The face protector 1 and the face protector frame of the present embodiment described above can be used in various fields. In particular, when it is used in the field of medical care or nursing care, a situation that requires urgency is assumed, but even in such a situation, the face protection device can be quickly and stably attached to the head with a simple operation. . A good fit can also be realized, so that a feeling of incongruity or pain does not occur even after prolonged use or repeated use.

  EXAMPLES Hereinafter, although this invention is demonstrated concretely based on an Example, this invention is not limited to these Examples.

Example 1
The face protector 1 described in the above embodiment was configured (Example 1). As the shield, a shield in which a through hole _Opn and a cutout _Cout were formed at both ends of the upper part was used.

(Comparative Example 1)
It was constructed using a straight body frame that was mounted so as to surround the head horizontally from the forehead. Specifically, a part of the ring smaller in diameter than the head is cut, the head is horizontally surrounded by the forehead as one of the fulcrum, and the both ends that are spread out are elastically deformed to return. A face protection device supported by the head was used.

(Comparative Example 2)
Wear the body frame that adopts the straight type of Comparative Example 1 at an angle (with the position closer to the top of the head than the forehead as one of the fulcrums, with both ends of the body frame positioned near the back of the head and neck) did. When wearing diagonally, the temples of the glasses and the body frame were expected to intersect. A face protector that comes into contact with the part was used.

(Comparative Example 3)
The front frame and the main body frame were configured by using a main body frame provided with protrusions on the left and right sides of the front side of the main body frame (side contacting the front head when worn) so that the front frame and the main body frame contact each other. Specifically, the left and right protrusions are brought into contact with the frontal head, and the face protection device is configured to support the back of the head by elastic deformation force that the both end portions that have been spread open return.

  In addition, although a lens frame was provided around the lens as a shield part, and a spectacle-type face protection device in which a nose pad and a pair of temple members were fixed to the lens frame, such a spectacle-type face protector was examined. The nose pad and temple member of the face protector interfere with each member of the glasses, making it difficult to use the glasses together.

(Sensory test 1)
A total of 10 men and women in their 20s to 50s were subjected to a sensory test that evaluated the fit comfort, vertical stability, and lateral stability in three stages when the shield was attached. The result of the test is “×” when judged unsuitable for use, “△” when judged unsuitable for use, “△” when evaluation is divided by “○”, “×” and “○”, When it was judged to be remarkably superior, it was evaluated as “◎”. The results are shown in Table 1.

  It was found that Comparative Example 1 had no sense of stability in the vertical direction (arrow A in FIG. 5 (a)). Further, in Comparative Example 1, it was also found that when the shield and the shield frame were attached to the front, the main body frame was easily detached from the head due to its weight.

  In Comparative Example 2, depending on the shape of the wearer's head, the front side of the main body frame is supported at only one point in the center of the frontal head, and both ends of the main body frame that supports the back of the head are fulcrums. It turned out that the shift | offset | difference which rotates or the shift | offset | difference of the left-right direction tends to arise (arrow A and B of FIG.5 (b)).

  Since Comparative Example 3 can support the head from 2 points on the frontal head and 2 points on the back of the head and 4 points in total, front and rear, left and right, the stability is higher than Comparative Examples 1 and 2, but the head is When it is large, the support point is greatly expanded by the forehead, thereby expanding the main body frame, and both ends for supporting the back of the head are excessively separated, and it has been found that the tightening of the rear support is weakened (Fig. 5 (c) Lb). That is, in Comparative Example 3, it was found that the head could not be worn stably regardless of whether the head was large or small.

  On the other hand, Example 1 was evaluated to be remarkably superior in all three items, and it was confirmed that the structure was superior to other configurations.

(Other embodiments)
Although one embodiment of the present invention has been described above, the basic configuration of the present invention is not limited to the above. For example, the present invention is not limited to the face protection device used in the field of medical care or nursing care as described in the above embodiment, and is intended to protect the entire face or a part of the face from dyeing splashes or chemicals. It is intended for face protectors and can of course be applied in other fields. For example, the present invention can be applied to the chemical field, ship / marine field, aviation / space field, textile field, metal field, resource engineering field, construction field, water and sewage field, sanitary engineering field, agricultural field, forest field, fishery field, environment. It can also be applied to fields such as nuclear power and radiation.

  In the above embodiment, a flexible transparent resin material is used as the shield S. However, a light adjusting material, a light absorbing material, or the like may be blended therein. The length of the shield is not limited, and the shield may have a length that protects the entire face from infectious droplets or chemicals, or a length that protects a part of the face, for example, the vicinity of the eyeball. It may have.

  The shield S may be provided with a predetermined protective sheet on at least one surface. According to this, since the surface of the shield S is protected by the protective sheet in the pre-use stage, it is possible to suppress the surface of the shield S from being scratched and the surface from being contaminated by dust in the air. Therefore, good visibility to the work object at the time of work can be secured, and if the shield S is used with the surface exposed for the first time by peeling off the protective sheet, low contamination to the work object is also secured. become able to. Moreover, sticking of the shields S can be prevented by attaching a protective sheet.

  If an antistatic property is imparted to the protective sheet, peeling from the shield S becomes easy, and if a colored protective sheet is used, it is determined whether or not the protective sheet is attached to the shield S. It becomes easy. Furthermore, if a peeling seal is attached to a predetermined position of the protective sheet and the protective sheet can be peeled off from the shield S by picking it, the peeling operation becomes easier.
