Such a support restricting piece 23 is formed by bending into a slightly curved plane substantially triangular shape, and the tip portion is folded back and fixed to the first band 20 with a mounting pin 22 so as to be detachably fixed to the second band 30. The hypotenuses project in the direction and come into contact with the vicinity of both ends thereof, and the second band 30 is greatly and widely curved to stabilize the arc shape.

As shown in FIG. 6, guide groove holes 25 for the second band 30 are cut out in an arc shape between the size adjusting hole 21 in the first band 20 and the end portion of the support restricting piece 23, respectively. Each guide groove hole 25 bends while rising from the size adjusting hole 21 direction toward the end portion of the support restricting piece 23. A support hole 26 for the second band 30 is formed in a circular shape in the vicinity of each guide groove hole 25.

As shown in FIGS. 2, 3, 5, and 7, the second band 30 is formed in a band shape in which the four corners are chamfered, and is formed slightly shorter than the first band 20. A plane-like crescent-shaped void 31 is formed between the band 20 and the surface thereof. The second band 30 has round support holes 32 drilled below both ends in the longitudinal direction, and a thumbtack-shaped support pin 33 penetrating the support holes 32 can be attached to and detached from the support holes 26 of the first band 20. By being inserted into the band 20, it is swingably supported by the first band 20. Like the mounting pin 22, the support pin 33 is molded from, for example, a molding material containing a predetermined resin (polystyrene resin or the like), and the tip portion of the shaft portion extending from the disk portion is formed in a mushroom shape, and the shaft portion is formed. Penetrates the support holes 32 and 26.

A guide hole 34 adjacent to the support hole 32 is circularly drilled above both ends in the longitudinal direction of the second band 30, and a thumbtack-shaped guide pin 35 penetrating the guide hole 34 is the first band 20. By being fitted into the guide groove hole 25 of the above, the second band 30 is guided by the guide groove hole 25 from 0 ° to 180 ° from the front direction to the rear direction, for example, 45 °, 60 °, 80 °, or. The center swings by 90 ° (see the arrow in FIG. 4). Like the mounting pin 22 and the support pin 33, the guide pin 35 is molded from a molding material containing, for example, a predetermined resin (polystyrene resin or the like), and the tip portion of the shaft portion extending from the disk portion is formed in a mushroom shape. The shaft portion penetrates the guide groove hole 25.

As shown in FIGS. 1 to 4, a replaceable adhesive layer 36 is fixed to the adhesive surface of the adhesive layer 36 by a thumbtack-shaped mounting pin 22 near the center of the surface of the second band 30. The resin film 40 is adhered. The adhesive layer 36 is made of a rubber material having a thin tack property (adhesiveness), is processed into a horizontally long sheet piece, and is detachably adhered to the upper portion, the upper end portion, and the like of the resin film 40.

As the rubber material of the adhesive layer 36, for example, low-hardness silicone, medium-hardness silicone, styrene-based thermoplastic elastomer, olefin-based elastomer, synthetic rubber and the like are used, but a silicone sheet having strong tackiness and adhesiveness is preferable. A low hardness silicone sheet is optimal. When the rubber material is silicone or the like having a general medium hardness, the hardness of about 50 ° is good from the viewpoint of cost and mass productivity. The surface of the rubber material is mirror-finished, if necessary, and a protective release resin film is peelably adhered.

Specific examples of rubber materials include tack sheets manufactured and sold by Sakase Chemical Co., Ltd. and Tomoe Engineering Co., Ltd. Specific examples of low-hardness silicone include low-hardness heat-dissipating silicone rubber sheet (adhesive on both sides) [Shin-Etsu Chemical Co., Ltd .: product name TC-50TXS], ultra-low-hardness silicone (MSG) [Sanshin Enterprise Co., Ltd .: product name. ], MSG-05 [manufactured by Kino Kiko Co., Ltd .: product name], etc. are applicable.

As shown in FIGS. 1 and 2, the resin film 40 is formed of a transparent planar rectangle having a predetermined size (for example, 315 mm × 315 mm, 360 mm × 310 mm, 240 mm × 240 mm, etc.), and the second band 30 is formed. By being detachably adhered to the surface of the adhesive layer 36 of the above, the wearer 1's face 4, specifically, at least the area from the forehead 3 to the chin is covered with the face 4 facing each other through a gap in a curved state like a flat bow. Functions to protect.

The resin film 40 is not particularly limited, but is, for example, a biaxially stretched polypropylene (OPP) resin film, a non-axially stretched polypropylene (CPP) resin film, a polyvinyl chloride (PVC) resin film, and an amorphous polyethylene. Examples thereof include a terephthalate (A-PET) resin film and a polyarylene ether ketone (PAEK) resin film. Among these, biaxially stretched polypropylene resin film and non-axially stretched polypropylene resin film are preferable, and they are excellent in printability, glossiness, impact resistance, water resistance, heat resistance, transparency, moisture resistance, and are environmentally friendly and inexpensive. Axial-stretched polypropylene resin film is most suitable.

Of the front and back surfaces of the resin film 40, at least the back surface (one side) facing the face 4 of the wearer 1 is selectively imparted with anti-fog property and hydrophilicity so as not to be fogged by the breath of the wearer 1. .. In this case, an anti-fog filler is added to the molding material at the time of molding the resin film 40, or the resin film 40 is coated with an anti-fog agent, an anti-fog film, or the like. The thickness of the resin film 40 is 40 μm or more, preferably 50 μm or more and 150 μm or less, more preferably 60 μm or more and 130 μm or less, and further preferably 60 μm or more and 100 μm or less.

The resin film 40 may be of a biodegradable type, a bio-based type, or the like, but is not particularly questioned. When the resin film 40 is a biaxially stretched polypropylene resin film, specific examples of the biaxially stretched polypropylene resin film are Shinetsu Polymer Co., Ltd., Sun Tox Co., Ltd., Futamura Chemical Co., Ltd., and Mitsui Chemicals Tocello Co., Ltd. Etc. are applicable.

The second band 30 is supported by the first band 20 while drawing a large, wide and loose arc, but the radius R of the second band 30 is larger than the conventional value as shown in FIGS. 1 and 5. The larger size is 80 mm or more, preferably 80 mm or more and 90 mm or less, more preferably 83 mm or more and 89 mm or less, and further preferably 84 mm or more and 88 mm or less. This is because when the radius R of the second band 30 is less than 80 mm, for example, when the conventional value is about 65 mm or 70 mm, light rays from the outside are reflected on the resin film 40, and the wearer 1 is affected by glare. This is because glare is generated.

From the experimental results, the radius R of the second band 30 is preferably 84 mm or more and 85 mm or less, preferably about 84.5 mm when the wearer 1 of the face shield is a child. On the other hand, when the wearer 1 of the face shield is an adult, it is preferably 87 mm or more and 88 mm or less, preferably about 87.5 mm.

In the above configuration, when the face shield is assembled and used, first, a pair of support restricting pieces 23 of the prepared first band 20 are raised, and each support restricting piece 23 is bent into a substantially triangular plane to form this support. By fixing the tip of the restricting piece 23 to the first band 20 with the mounting pin 22, the support restricting piece 23 is projected toward the surface side of the first band 20. Further, both ends of the adhesive layer 36 are fixed to the vicinity of the center of the surface of the second band 30 by a pair of mounting pins 22 for preventing the adhesive layer 36 from falling off, and the adhesive layer 36 is laminated.

Next, the support holes 26 and 32 of the first and second bands 20 and 30 are overlapped and the support pins 33 are attached to them, and the guide holes 34 of the second band 30 and the guide groove holes 25 of the first band 20 are attached. A guide pin 35 is inserted into these so that the first band 20 can swingably support the second band 30, and the pair of support restricting pieces 23 in the first band 20 are supported by the second band 30. Make contact near both ends of the inner surface of the.

After the second band 30 is swingably supported by the first band 20 in this way, the upper part of the resin film 40 is detachably adhered to the adhesive layer 36 of the second band 30, and the first band 20 is curved. Then, a plurality of selected size adjustment holes 21 at both ends thereof are overlapped with each other, and a mounting pin 22 is inserted into them, and the first band 20 curved in a ring shape is fitted to the head 2 of the wearer 1.

At this time, since the adhesive layer 36 is laminated on the surface of the second band 30, the resin film 40 can be appropriately adhered regardless of the material and transparency of the resin film 40. Further, the resin film 40 without an adhesive can be appropriately adhered. Further, since the resin film 40 can be adhered to the adhesive layer 36 while finely adjusting it up, down, left and right, the face 4 of the wearer 1 can be effectively used regardless of the presence or absence of the wearer 1's glasses or mask. Can be protected.

After that, the fitting condition of the first band 20 to the head 2 of the wearer 1 is examined, and if necessary, the plurality of size adjusting holes 21 in the first band 20 are changed and the mounting pin 22 is refitted. If you insert it, you can assemble and use the face shield.

With the face shield, the wearer 1 can engage in work or the like while protecting the face 4 from pathogens or the like. At this time, if the movable second band 30 is pulled upward at a predetermined angle, the lower portion of the resin film 40 comes into contact with the wearer 1's neck and chest even if the wearer 1 faces downward. Since there is no such thing, you can work with the same work efficiency as usual, and you can eat and drink with confidence without removing the face shield. Further, since the strength of the resin film 40 is increased due to the bending of the resin film 40, the resin film 40 is less likely to be deformed by being blown by wind or the like, resulting in deterioration of the protective function of the face shield.

When the work or the like is completed, the resin film 40 may be peeled off from the adhesive layer 36 of the second band 30 in the face shield band 10 and discarded. When the face shield band 10 is used again after discarding the resin film 40, the upper part of the newly prepared resin film 40 is detachably adhered to the adhesive layer 36 of the second band 30, and then the first By finely adjusting the positions of the band 20 and the resin film 40, the face shield band 10 can be reused.

According to the above configuration, the radius R of the second band 30 is set to 80 mm or more, the arc is widely expanded to the outside, reflection and the like are prevented, and glare is prevented from occurring in the wearer 1. It is possible to reduce the occurrence of tension and fatigue in the eyes of No. 1, and it is possible to solve the problem of hindering the visibility of the wearer 1. Further, since it is not necessary to apply antiglare treatment to the resin film 40 or to adopt the antiglare resin film 40, the transparency of the resin film 40 does not deteriorate.

Further, since the adhesive layer 36 exerts an adhesive action, it is not necessary to apply and laminate a dedicated adhesive layer 36 in a band shape on or near the peripheral edge of the resin film 40, facilitating the production of the resin film 40. , Speeding up, facilitation, and mass production can be greatly expected. Further, since the gap 31 between the first and second bands 20 and 30 divides the air flow passage and the amount of air flow increases, it is necessary to eliminate the suffocation of the wearer 1 when using the face shield. Can be done. Further, since the resin film 40 can be thrown away, it is not necessary to sterilize the contaminated resin film 40 with a disinfectant and use it, and it is possible to solve the hygienic problem.

Further, when the adhesive layer 36 is a low-hardness silicone, when dust adheres to the low-hardness silicone and becomes dirty, if the dust of the low-hardness silicone is wiped off with water or alcohol, the tackiness of the low-hardness silicone is restored. It is highly expected that the adhesive layer 36 will be used repeatedly for a long period of time. Further, when the adhesive layer 36 is made of low-hardness silicone, if the surface of the low-hardness silicone is mirror-finished, the adhesion for the resin film 40 can be greatly improved. Further, when the resin film 40 is an inexpensive biaxially stretched polypropylene resin film, it is possible to reduce the running cost and greatly improve the productivity. Further, since a large number of resin films 40 can be folded or rolled and transported at one time, it becomes possible to facilitate storage and transportation.

Next, FIG. 8 shows a second embodiment of the present invention. In this case, both side portions of the first band 20 are formed into a pair of left and right support restricting pieces 23, and each support restricting piece 23 is formed. The second band 30 is bent outward to form a substantially U-shaped plane and is brought into contact with the vicinity of the inner surface of the end of the second band 30 curved in an arc shape. I am trying to do the above.

A mounting pin 22 that maintains the shape of the support restricting piece 23 having a substantially U-shaped plane is fitted into the first band 20 and the short inner side portion of each support restricting piece 23. Further, guide groove holes 25 for the second band 30 are cut out in an arc shape in the vicinity of both side portions of the first band 20, and the second band 30 is in the vicinity of each guide groove hole 25. Support hole 26 for use is drilled in a circular shape. Since other parts are the same as those in the above embodiment, the description thereof will be omitted.

Also in this embodiment, the same effect as that of the above embodiment can be expected, and since the support restricting piece 23 is bent and formed in a substantially U-shape on the outside instead of the inside, the arc of the second band 30 is expanded. be able to. Further, it is clear that the manufacturing work of the first band 20 is facilitated because it is not necessary to punch a plurality of elongated horizontal U-shapes in the vicinity of the central portion of the first band 20.

Although the first band 20 is simply shown in the above embodiment, the back surface (inner surface) of the first band 20 is embossed to reduce the contact area of the wearer 1 with the head 2 for hygiene. You may try to contribute to. Further, in the above embodiment, the mounting pin 22, the support pin 33, and the guide pin 35 are substantially thumbtack-shaped, but the present invention is not limited thereto. For example, a pair of button-shaped attachments, supports, guides, and the like that are fitted to each other may be used.

Further, in the above embodiment, the adhesive layer 36 is replaceably fixed to the surface of the second band 30 by the mounting pin 22, but if there is no need for replacement, an adhesive is applied and dried and cured. The adhesive layer 36 may be laminated and the mounting pin 22 may be omitted. As the pressure-sensitive adhesive, natural rubber-based, synthetic rubber-based pressure-sensitive adhesives such as butadiene rubber, styrene-butadiene rubber, chloroprene rubber, nitrile rubber, and butyl rubber, and acrylic-based pressure-sensitive adhesives are used. When the adhesive is acrylic, it is excellent in weak adhesiveness, durability, heat resistance, moisture resistance, weather resistance, aging resistance, etc., has a wide range of adhesive strength, and can be expected to reduce ultraviolet deterioration.

Further, in the resin film 40 of the above embodiment, in addition to the above resin and filler, an antioxidant, a light stabilizer, an ultraviolet absorber, a plasticizer, a lubricant, a flame retardant, and an antistatic agent, as long as the transparency is not hindered. An inhibitor, a heat resistance improver, or the like may be added as needed. Further, the assembly order of the face shield can be changed as appropriate.

The face shield according to the present invention is used in fields such as medical treatment, nursing care, home, retail business, dentistry, manufacturing, customer service, pruning, and agricultural work.
