Protective equipment used for purposes such as preventing infectious diseases consists, for example, of a film that covers part or all of the user's face and is fixed to a frame that can be worn on the user's head.

Some protective equipment frames are made of a roughly annular flexible member and are worn to encircle roughly the entire head of the user of the protective equipment (see, for example, Patent Document 1).

Utility Model Registration No. 3227824

When using the protective equipment described in Patent Document 1, the frame is attached to the head so as to surround the head from above. However, when attaching the frame, there are cases where the film fixed to the frame hits the face, making it difficult to attach the frame smoothly. In addition, if the film is in front of the face while wearing the protective equipment, it is not possible to eat or drink, for example, and it is necessary to remove the protective equipment from the head in order to eat or drink. This can result in a large burden on the user when putting on and taking off the protective equipment.

The present invention has been made in consideration of the above circumstances, and an object of the present invention is to achieve the objects described below.
SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to solve the above-mentioned problems of the conventional technology and to provide a frame that is easy to wear and highly convenient.

The frame and protective equipment of the present invention will be described in detail below with reference to two preferred embodiments (first and second embodiments) shown in the attached drawings. Note that the embodiment described below is merely one of the specific examples given to facilitate understanding of the present invention, and is not intended to limit the present invention. In other words, the present invention may be modified or improved from the embodiment described below without departing from the spirit of the present invention. Furthermore, it goes without saying that the present invention includes its equivalents.

In addition, in this specification, when describing the position and state of each part of the frame of the present invention, unless otherwise specified, the position and state when the frame is worn will be described. In addition, in the following description, "front" and "rear" mean "front" and "rear" as seen from the perspective of a wearer wearing the frame, and "top" and "bottom" mean "top" and "bottom" as seen from the perspective of a wearer wearing the frame.

(Regarding the first embodiment)
A frame according to a first embodiment of the present invention (hereinafter, frame 10) is a frame to which a face protection film (hereinafter, film 50) is fixed and which can be worn on the head of a user. That is, the frame 10 and the film 50 constitute the protective equipment 1 shown in FIG.

Protective equipment 1 is a so-called face guard or mouth shield, and its main purpose is to prevent the scattering of droplets such as saliva emitted from the user's mouth. That is, film 50 is a film for preventing the scattering of droplets, and when frame 10 is attached to the head, it is positioned so as to cover at least the mouth part of the user's face, as shown in FIG. 3. Note that protective equipment 1 functioning as a face guard (protective equipment shown in FIGS. 1 to 4) can also be used to prevent droplets and floating objects from adhering to the user's face. In that case, film 50 can also be positioned so as to cover the eyes of the face.

The material and dimensions of the film 50, such as thickness, are not particularly limited. For example, the material of the film 50 is preferably one that is highly transparent (light transmittance) so that the user's face can be clearly seen when the protective equipment 1 is used, and a colorless and transparent material is particularly preferable. This is because when the frame 10 of the present invention and the film 50 are combined, the visual effect of particularly weakening the impression that the user is wearing the protective equipment 1 is high. Examples of suitable materials for the film 50 include films such as triacetylcellulose (made by TAC), polyethylene terephthalate, and polycarbonate. Triacetylcellulose is preferable in terms of transparency. It is also preferable to apply an anti-reflective coat to one or both sides of the film 50. In addition, the thickness of the film 50 is preferably 80 μm or more in terms of strength when the film 50 is placed between the frames 10 so as to face the front of the face, and is preferably 500 μm or less in terms of the ease of bending and weight of the film 50 when the film 50 is placed on the frame 10. More preferably, it is 100 μm or more and 300 μm or less, and even more preferably, 110 μm or more and 250 μm or less.

As shown in FIG. 1, the frame 10 has a three-dimensionally folded shape and is symmetrical with respect to the center position in the frame width direction. More specifically, the frame 10 has a frame rear portion 11 that extends in an arc shape. Also, as shown in FIG. 1, one end of the frame 10 is provided with a first opposing portion 12, a first bent portion 13, and a first extending portion 14, in that order from the side closest to the frame rear portion 11, and the first extending portion 14 is provided with a first supporting portion 15. The other end of the frame 10 is provided with a second opposing portion 16, a second bent portion 17, and a second extending portion 18, in that order from the side closest to the frame rear portion 11, and the second extending portion 18 is provided with a second supporting portion 19.

All or a part of the above-mentioned frame 10 (for example, the rear frame portion 11, the first opposing portion 12, the first bent portion 13, the first extending portion 14, the second opposing portion 16, the second bent portion 17, and the second extending portion 18) may be made of, for example, resin or metal. The material of the frame 10 can be appropriately selected from the viewpoints of design such as lightness in terms of usability and ease of visibility when worn, rigidity of the material for imparting strength to the frame 10 and the protective equipment 1, workability for forming the frame shape, and material cost. If the frame 10 is made of metal, sufficient strength can be ensured even if it is thin, and the thinner it is, the less noticeable it becomes when worn. The metal used as the material for the frame 10 is preferably steel, stainless steel, or a relatively lightweight metal such as aluminum or titanium, or an alloy thereof. In addition, the shape of the metal may be a long and thin core wire shape such as a wire or a wire, or a ribbon shape having a certain width. Furthermore, the protective equipment 1 of the present invention may be used in combination with glasses. In that case, the temples and frame 10 (strictly speaking, the first opposing portion 12 and the second opposing portion 16) of the glasses will be worn above the base of the ears, so it is preferable to make the frame 10 thin or flat, for example, in a vertically long ribbon-like or elliptical shape. The material and shape of each part of the frame 10 are not particularly limited, and for example, all or part of the frame 10 may be a resin molded product such as plastic.

A part of the frame 10 may be different from the other parts, for example, the first support part 15 and the second support part 19 may have a different configuration from the other parts. Specifically, the first support part 15 and the second support part 19 may be made of a resin molded product, and the other parts may be made of a metal core wire. Also, a part of the metal core wire (for example, the frame rear part 11, the first opposing part 12, the first bent part 13, the second opposing part 16, and the second bent part 17) may be covered with resin, cloth, paper, or the like. However, the frame 10 may be, for example, a one-piece molded product, in other words, each part of the frame 10 may be made of the same material. In this case, the frame 10 can be manufactured more easily.

In addition, since the frame 10 is intended to be used as an ornament, various parts of the frame 10 may be decorated.

Each part of the frame 10 will be described in detail below. The rear frame part 11 is an arc-shaped curved part that is open at its front end. The rear frame part 11 is also elastic, and when the frame 10 is attached, it elastically deforms so that the degree to which the front end opens increases (in other words, so that the curvature of the rear frame part 11 decreases).

As shown in Figs. 1 to 4, the first opposing portion 12 is adjacent to the frame rear portion 11 at one end (specifically, the right end) of the frame rear portion 11 and corresponds to an extended portion of the frame rear portion 11. That is, the first opposing portion 12 extends along the frame rear portion 11 toward the front end of the frame 10. The first opposing portion 12 is gently curved in an S-shape when the frame 10 is viewed from the side. The second opposing portion 16 is symmetrical to the first opposing portion 12, is adjacent to the frame rear portion 11 at the other end (specifically, the left end) of the frame rear portion 11, and extends along the frame rear portion 11 toward the front end of the frame 10. Each of the first opposing portion 12 and the second opposing portion 16 is continuous with the frame rear portion 11 and has the same thickness (or width) as the frame rear portion 11.

As shown in Figs. 1 to 4, the first bent portion 13 is a portion that continues to the first opposing portion 12 on the opposite side to the rear frame portion 11. The first bent portion 13 is bent in a substantially L-shape so that the end (front end) on the opposite side to the first opposing portion 12 faces upwards of the head. The second bent portion 17 is symmetrical to the first bent portion 13 and is a portion that continues to the second opposing portion 16 on the opposite side to the rear frame portion 11. The second bent portion 17 is also bent in a substantially L-shape so that the end (front end) on the opposite side to the second opposing portion 16 faces upwards of the head. The first bent portion 13 and the second bent portion 17 form the front end portion of the frame 10, and each bent portion is present at the front end of the frame 10.

As shown in Figs. 1 to 4, the first extension 14 is a portion that extends from the end (upper end) of the first bent portion 13 opposite the first opposing portion 12 toward the top of the head. As shown in Figs. 3 and 4, the first extension 14 extends in a substantially vertical direction. In addition, the end of the first extension 14 opposite the first bent portion 13 is bent outward in an L-shape along the width direction of the film 50, and a first shaft 14a is formed for fixing to the first support portion 15. The second extension 18 is symmetrical to the first extension 14, and is a portion that extends from the end (upper end) of the second bent portion 17 opposite the second opposing portion 16 toward the top of the head. In addition, a second shaft 18a is formed at the end of the second extension 18 opposite the second bent portion 17 for fixing to the second support portion 19.

As shown in Figs. 1 to 4, the first support portion 15 is attached to one end of the film 50 in the width direction in order to rotatably fix the film 50 to the first extension portion 14. As shown in Figs. 5 to 7, the first support portion 15 has an outer member 31 and an inner member 32, which are plate-shaped attachment members, and supports the film 50 by sandwiching it in the gap formed between the outer member 31 and the inner member 32. The outer member 31 is provided with an insertion hole 33 for inserting the first extension portion 14 (strictly speaking, the first shaft portion 14a), and the inner member 32 is provided with a notch 34 from above. The notch 34 is a key groove, and is a hole through which the first extension portion 14 can pass as shown in Fig. 7. The insertion hole 33 is located in a position facing the notch 34 and is provided in a position facing the lower end of the notch 34.

The outer member 31 and the inner member 32 are provided with fitting holes (not shown) at positions corresponding to fitting holes (not shown) formed at one end of the film 50 in the width direction when the film 50 is clamped. As a result, after the film 50 is clamped between the outer member 31 and the inner member 32, a fastener screw 35 is inserted with the fitting holes of the outer member 31 and the inner member 32 overlapping with the fitting hole of the film 50. As a result, the first support portion 15 supports one end of the film 50 in the width direction.

The second support part 19, like the first support part 15, is attached to the other end of the film 50 in the width direction in order to rotatably fix the film 50 to the second extension part 18. The second support part 19 has a structure similar to that of the first support part 15, and supports the other end of the film 50 in the width direction in the same manner as the first support part 15.

As described above, the width direction ends of the film 50 are supported by the first support portion 15 and the second support portion 19. This allows the film 50 to span between the two side ends of the frame 10 in a bow-shaped bent state.

The film 50 is rotatably fixed to the first extension portion 14 and the second extension portion 18 via the first support portion 15 and the second support portion 19. Specifically, the end of the first extension portion 14 on the first shaft portion 14a side is aligned with the notch 34, and the end of the first extension portion 14 is inserted into the gap between the outer member 31 and the inner member 32 through the notch 34 as shown in FIG. 7. At this time, the first shaft portion 14a is inserted into the insertion hole 33 with some play in the insertion hole 33. This allows the first shaft portion 14a to rotate within the insertion hole 33. In addition, as the first shaft portion 14a rotates, the first extension portion 14 swings (rotates) between the outer member 31 and the inner member 32 with the first shaft portion 14a as a fulcrum, as shown in FIG. 6. As a result, one end of the film 50 is supported by the first support portion 15 in a state in which it can rotate around an axis along the width direction of the film 50 relative to the first extension portion 14.

The second support part 19 has a symmetrical structure to the first support part 15, and with the same structure as above, the other end of the film 50 is supported by the second support part 19 in a state in which it can rotate around an axis along the width direction of the film 50 relative to the second extension part 18.

In the first embodiment, the film 50 can be removed from the first support part 15 and the second support part 19 by removing the screws 35 that are fitted into the fitting holes of the outer member 31 and the inner member 32 and the fitting holes of the film 50. In this way, each of the first support part 15 and the second support part 19 may fix the film 50 in a state in which the film 50 is detachable from each of the first support part 15 and the second support part 19. In this case, the used film 50 can be removed from the frame 10 and replaced with a new film 50. However, this is not limited to the above, and the first support part 15 and the second support part 19 may fix the film 50 in an undetachable manner.

In addition, while allowing the film 50 to rotate relative to the first extension portion 14 and the second extension portion 18, it is necessary to prevent the film 50 from rotating relative to the first support portion 15 and the second support portion 19 (e.g., rotating around the screw 35). From that perspective, in the first embodiment, at least one of the first support portion 15 and the second support portion 19 may have two or more fixing points. In the case shown in Figures 1 to 4, each of the first support portion 15 and the second support portion 19 is fixed by two screws 35 (see Figure 5) as two fixing points.

Instead of the screws 35, the first support portion 15 and the second support portion 19 may be provided with fitting protrusions (not shown) that fit into fitting holes on the film 50 side. Alternatively, a fitting protrusion may be provided on the film 50 side, and fitting holes may be provided on each of the first support portion 15 and the second support portion 19. The cross-sectional shape of the fitting protrusion may be a shape other than a circle, specifically an ellipse, a polygon, a star, or the like. With these shapes, it is possible to prevent the film 50 from rotating relative to the first support portion 15 and the second support portion 19, even if it does not necessarily have two or more fixing points.

The structure for fixing the film 50 by the first support part 15 and the second support part 19 is not limited to the screw 35 or the recessed and protruding fitting structure between the fitting protrusion and the fitting hole. For example, a fixing structure using a snap fit method, or a structure in which the film 50 is fixed by hooking the tip part of a hook-shaped tip onto the edge of the film, etc., can also be used. Alternatively, the first support part 15 and the second support part 19 may be structured to simply clamp the film 50 like a clip, etc.

The film 50 supported by the first support portion 15 and the second support portion 19 in this manner is fixed in a rotatable state relative to the frame 10.

Specifically, the film 50 and the first and second support portions 15 and 19 rotate about an axis (i.e., the first axis portion 14a) along the width direction of the film 50 relative to the first and second extension portions 14 and 18. This causes the state of the film 50 to change according to the rotational position at that time, and more specifically, the frame 10 and the film 50 can be switched between a first state shown in FIG. 5, a second state shown in FIG. 6, and a third state shown in FIG. 7.

In the first state, the first extension 14 of the frame 10 is housed in the gap of the first support 15. In the first state, as shown in FIG. 3, the first extension 14 abuts against the end (side surface) of the film 50 in the width direction, and is configured not to rotate beyond this position toward the film 50.

In the second state, the first extension portion 14 and the second extension portion 18 are rotated approximately 90 degrees from the first state. In the second state, the film 50 is rotated and flipped up toward the face, as shown in FIG. 4.

In the third state, the first extension portion 14 and the second extension portion 18 rotate approximately 180 degrees from the first state and move along the notch 34 to a position adjacent to the notch 34. In this state, the first extension portion 14 and the second extension portion 18 can be detached from the first support portion 15 and the second support portion 19 by pulling the first extension portion 14 and the second extension portion 18 out of the notch 34, which is the key groove.

The first support portion 15 and the second support portion 19 are not limited to a structure fixed to the film 50 side. As shown in FIG. 8, for example, they may be rotatably fixed to the frame 10 side and detachably attached to the film 50. Specifically, the second support portion 19 has a groove 36 on the rear side that is large enough to accommodate the second extension portion 18, and the second extension portion 18 is rotatably held in the groove 36 by a holding mechanism (not shown) with the connecting portion 37 as a rotation axis. On the other hand, a gap is provided on the front side for sandwiching and supporting the film, and a fitting hole 38 is provided at a position corresponding to a fitting hole 39 formed at one end of the film 50 in the width direction when the film 50 is sandwiched. As a result, the film 50 is sandwiched in the gap, and a fastener screw (not shown) is inserted with the fitting hole 38 of the second support part 19 and the fitting hole 39 of the film 50 overlapping, and the inserted screw fits into the fitting hole 38 and the fitting hole 39, fixing the second support part 19 to one end of the film 50 in the width direction. With the above configuration, one end of the film 50 can be rotated relative to the frame 10 by rotating the second extension part 18 with the connecting part 37 as a fulcrum.

When the frame 10 described above is attached to the user's head (hereinafter referred to as the frame attached state), the rear part 11 of the frame comes into contact with the back of the user's head along the back of the head, as shown in Figures 3 and 4.

When the frame is attached, the first opposing portion 12 abuts against one side of the head (specifically the left side), and although not shown, the second opposing portion 16 abuts against the other side of the head (specifically the right side). Explaining in more detail, the frame 10 is attached to the head with the rear portion 11 of the frame elastically deformed, so a restoring force is generated in the frame 10. This restoring force allows the frame 10 to be attached with the head sandwiched between the first opposing portion 12 and the second opposing portion 16, and the attached state of the frame 10 can be maintained in a good condition.

When the frame is worn, as shown in Figures 3 and 4, the first opposing portion 12 and the second opposing portion 16 are positioned above the base of the user's ear and toward the front (face). In other words, each of the first opposing portion 12 and the second opposing portion 16 abuts against the temporal region at a position at least above the base of the ear. In this way, the frame 10 according to the first embodiment is worn by hooking it onto the base of the ear like the frame (temple portion) of glasses.

The first bent portion 13 and the second bent portion 17 are each located forward of the ear (toward the face) and at the same height as or slightly above the upper end of the base of the ear. The first extending portion 14 and the second extending portion 18 are each located forward of the ear (toward the face) and above the upper end of the base of the ear. More specifically, the first bent portion 13 and the second bent portion 17 are each located, for example, near the temple, and the first extending portion 14 and the second extending portion 18 are each located, for example, above the temple (see Figures 3 and 4).

When the frame is attached and the frame 10 is in the first state, the film 50 faces the user's face in front of the face, as shown in FIG. 3. At this time, at least a part of the film 50 is located in front of the mouth of the face. In other words, when the frame is attached, the film 50 supported by the first support portion 15 and the second support portion 19 is positioned in a position where at least the mouth of the face is covered by the film 50 (hereinafter also referred to as the use position).

When a film 50 with a sufficiently long vertical length is used, such as in the face shield guard type protective equipment 1 shown in Figures 1 to 4, when the frame 10 is in the first state, the film 50 supported by the first support portion 15 and the second support portion 19 is positioned so that the entire face is covered by the film 50.

In addition, when the film 50 rotates relative to the frame 10 as a result of the frame 10 transitioning from the first state to the second state, the film 50 moves from the use position shown in FIG. 3 to the retracted position shown in FIG. 4. In other words, the film 50 rotates toward the top of the face and is flipped up. In this way, by switching the state of the frame 10 between the first state and the second state, the film 50 can be easily moved from the use position to the retracted position, or from the retracted position to the use position.

When the frame 10 is in the second state, the film 50 is separated from the first extension 14 and the second extension 18 of the frame 10 as shown in FIG. 4, so that the frame 10 can be easily attached and detached. Even when worn, if the film 50 is flipped up to change from the first state to the second state, it is not necessary to remove the frame 10 to eat or drink, and it is possible to eat or drink with the film 50 attached. Furthermore, by transitioning the frame 10 from the first state to the third state, the film 50 can be easily removed from the frame 10 (more precisely, the part of the frame 10 excluding the first support 15 and the second support 19) together with the first support 15 and the second support 19. In this way, the ease of attaching and detaching the frame 10 and the convenience of using the protective equipment 1 are improved, and the burden on the user can be reduced for the protective equipment 1 having a structure in which the frame is supported on the back of the head.

The frame 10 of the first embodiment also provides an excellent wearing comfort. In other words, when the frame is attached, the film 50 and frame 10 do not touch the user's face, so the load on the face (contact pressure from the film 50 and frame 10) while wearing the protective equipment 1 can be reduced.

In addition, since the frame 10 is positioned near the back and sides of the head when the frame is worn, the frame 10 is not in the user's field of vision (widening the field of vision), and is not noticeable when the face of a user wearing the protective equipment 1 is viewed from the front. Furthermore, by increasing the transparency of the film 50, a visual effect can be achieved that makes it difficult to recognize the presence of the transparent plate.

Furthermore, since the frame 10 wraps around the back of the user's head to hold the film 50 in front of the face and is worn hooked on the user's ear, a downward force due to the weight of the film 50 acts on the front side of the frame 10 (i.e., the film 50 side) of the frame 10. This load causes the frame 10 to rotate around the point where it is hooked on the user's ear, but the rear part 11 of the frame hooks on the back of the head, so the frame can resist the above force and maintain a good attached state.

Second Embodiment
A frame (hereinafter, frame 20) according to a second embodiment of the present invention will be described with reference to Figures 9 and 10. The frame 20 according to the second embodiment is a frame 20 used in a so-called mouth shield type protective equipment 1X, and a film 50 having a relatively short length in the vertical direction is used as the film 50.

The frame 20, like the frame 10 of the first embodiment, constitutes the protective equipment 1X shown in Figures 9 and 10, and can be worn on the user's head by fixing a face protection film 50 to the frame 20. The material of the frame 20 is the same as that of the frame 10 of the first embodiment, so a description thereof will be omitted. Note that, like the first embodiment, a portion of the frame 20 is preferably made of metal, particularly a linear metal material such as a wire, in order to make it thin so that it is less noticeable when worn.

The following will focus on the differences in the structure of the frame 20 from the frame 10 of the first embodiment. As shown in Figures 9 and 10, the frame 20 has a symmetrical (bilaterally symmetrical) structure with respect to the center position in the width direction. The frame 20 has a frame rear portion 21, a first opposing portion 22, a first bent portion 23, a first extending portion 24, and a first supporting portion 25. Note that on the opposite side in the width direction, there is a second opposing portion, a second bent portion, a second extending portion, and a second supporting portion, but as the structure is symmetrical, they are not shown in the figures.

The first opposing portion 22 of the frame 20 and the second opposing portion (not shown) are curved in a shape different from the first opposing portion 12 and the second opposing portion 16 of the frame 10 in the first embodiment.

As shown in Figures 9 and 10, unlike the frame 10 of the first embodiment, the first bent portion 23 is bent in a generally L-shape so that the end opposite the first opposing portion 22 faces downward toward the head (face). The second bent portion (not shown) is symmetrical to the first bent portion 23, and is bent in a generally L-shape so that the end opposite the second opposing portion faces downward toward the head (face).

As shown in Figures 9 and 10, the first extension 24 is a portion that extends downward from the head (face) from the end (lower end) of the first bent portion 23 opposite the first opposing portion 22. The second extension (not shown) is symmetrical to the first extension 24 and is a portion that extends downward from the head (face) from the end (lower end) of the second bent portion opposite the second opposing portion. A first support 25 and a second support (not shown) are attached to the ends of the first extension 24 and the second extension, respectively.

In the frame 20 of the second embodiment, the width direction ends of the film 50 are also supported by the first support portion 25 and the second support portion. In other words, the film 50 is supported by the first support portion 25 and the second support portion in a state in which it can rotate with respect to the first extension portion 24 and the second extension portion. This causes the film 50 to span between the two side ends of the frame 20 in a bow-shaped bent state.

In the frame-attached state, as shown in Figures 9 and 10, the rear frame portion 21 contacts the back of the user's head along the back of the head. When the frame is attached and the frame 20 is in the first state, the film 50 faces the user's face in front of the face as shown in Figure 9. At this time, at least a portion of the film 50 is located in front of the mouth of the face. In other words, in the frame-attached state, the film 50 supported by the first support portion 25 and the second support portion is positioned in a position where at least the mouth of the face is covered by the film 50.

On the other hand, in the second embodiment, as in the first embodiment, the film 50 is fixed to the frame 20 so as to be rotatable. That is, in the second embodiment, the film 50 is also configured to be freely movable between a use position and a retracted position as shown in FIGS. 9 and 10. Therefore, even in a state where the frame is attached, if the frame 20 is transitioned from the first state to the second state to lower the film 50, it becomes possible to eat and drink with the frame 20 attached without having to take off the frame 20 to eat and drink. In this way, the ease of putting on and taking off the frame 20 and the convenience of using the protective equipment 1X are improved, thereby reducing the burden on the user.
