Description

The present invention relates to a nose-mouse shield that covers the upper and anterior parts of a person's nose and mouth and intends to guide the exhaled droplets downward and posteriorly.

Microorganisms such as viruses may adhere to droplets and float in the air, and when a person inhales these viruses together with the droplets into the respiratory tract, it may have an adverse effect on the human body such as an infectious disease. Viruses, etc. adhere to the droplets spewed out by coughing, sneezing, or vocalization of those who carry them in their bodies (especially infected persons) and are released into the air. It sinks downward. In addition, the airborne time of droplets is also related to the humidity in the air, and the airborne time of droplets is longer in winter when the humidity is low than in summer when the humidity is high. For this reason, especially in winter, the frequency of inhalation of droplets into the respiratory tract by a third party is higher than in summer, and the amount of droplets inhaled also increases. And become popular. To prevent this, prevent the released droplets from scattering forward and upward, and avoid the situation where the droplets in the air diffuse and float near the face (head) of a third party as much as possible. It becomes important to do.

Conventionally, a mask is known as a tool for suppressing the release of droplets. However, depending on the usage environment and usage conditions, there are situations in which wearing a mask makes it difficult to breathe and removes the mask, and there are also situations in which it is not suitable to wear a mask because the mouth cannot be seen. Even in such a case, as a tool for the purpose of preventing the droplets from directly reaching the vicinity of the other party's face (head), the front of the nose and mouth as shown in Patent Document 1. A mouth shield that blocks the bottom is known.

The mouth shield of Patent Document 1 is formed of a sheet-like member that can be bent as a whole, and the sheet-like member is arranged in front of the mouth of the user who wears the mouth shield, and has a shield portion having a lateral length of the mouth. It is provided with a band portion that is long in the lateral direction at a position that covers the user's jaw, and a connecting portion that connects the shield portion and the band portion in the center in the left-right direction. Further, the mouth shield has a chin contact portion that rises from the connecting portion to the user side, and ear straps provided at both ends in the lateral direction of the sheet-shaped member.

When using, place the chin contact part on the chin of a person and hang the ear strap on the ear, so that the nose and the lower part of the front of the mouth are covered with the shield part, but the part above the height of the tip of the nose is open. It is in a state (structure).

By the way, as described above, in order to prevent infection with a virus or the like, it is important to prevent the droplets from diffusing and reduce the amount of suspended droplets in the air as much as possible. Is in an open state (structure) above the height of the tip of the nose, so the airborne time until the released droplets scatter upward and forward, soar and diffuse, and sink downward is long. However, there may be some inconveniences that make it a little longer. Also, like the mask, it is necessary to remove it when eating and drinking, so it is easy to be in an unprotected state during that time, and when carrying the removed mouse shield, it has a slightly three-dimensional shape like a drum bridge. Therefore, the larger the size of the shield portion, the stronger the tendency to be bulky.

Japanese Unexamined Patent Publication No. 2020-180425

The present invention suppresses the droplets released from the nose and mouth from scattering forward and upward and forward, and promotes rapid subsidence by mainly guiding the droplets downward and backward, and reduces the floating time of the droplets in the air. An object of the present invention is to provide a nose / mouth shield that can be shortened and folded to make it easy to carry.

[1] A nose / mouth shield that covers the upper part and front of a person's nose and mouth.
A nose shield portion formed thinly and covering from the nose to the cheek of the person, a connecting hinge provided at the lower part of the nose shield portion, and a connecting hinge provided on the nose shield portion so as to be rotatable in the vertical direction via the connecting hinge. A mouse shield that covers the front of the mouth is provided.
The nose shield portion includes an upper surface shield main body whose upper portion is in contact with the nose and cheeks and is inclined forward downward, and ear hook portions foldable on both sides of the upper surface shield main body and hung on ears. It is characterized by being.

According to such a configuration, the nose / mouth shield includes a nose shield portion that covers from the nose to the cheek, a connecting hinge, and a mouth shield portion that is provided via the connecting hinge and covers the front of the mouth. Since the nose shield portion includes an upper surface shield main body whose upper part is in contact with the nose and cheeks and is inclined forward downward, the front of the mouth is covered with the mouth shield portion and the upper part of the nose is the upper surface shield main body of the nose shield portion. It can be covered with, and it is possible to prevent the droplets released from the nose and mouth from scattering forward and upward.

Furthermore, since the upper part of the upper shield body is in contact with the nose and cheeks and tilts forward, even if the wearer coughs, most of the droplets will come out between the upper shield body and the nose and cheeks. Instead, it is guided downward along the upper surface shield body that is inclined forward and the front mouth shield portion, and is quickly discharged to the lower part of the mouth (partly in both lateral directions) and sinks. This means that by changing the direction of the energy that the droplets try to disperse forward, the droplets directly reach the vicinity of the opponent's face (head) in front of them, both spatially and spatially. , It is a deterrent in terms of time. Therefore, it is possible to prevent the droplets from diffusing and floating near the face (head) of the other party, and to shorten the floating time of the discharged droplets in the air.

Further, since the ear hooks are foldable on both sides of the upper surface shield main body, the ear hooks can be folded to make them compact when not worn, and can be easily carried by putting them in a pocket or the like, for example. Furthermore, when eating or drinking, if the mouth shield is rotated upward from the connecting hinge and flipped up with the nose and mouth shield attached, food can be carried to the mouth without removing the nose and mouth shield itself. it can.

[2] Preferably, in the upper surface shield main body, a nasal recess formed along the shape of the nose is formed in the upper portion in contact with the nose, and the upper portion in contact with the cheek is formed along the shape of the cheek. A dented cheek recess is formed.

According to such a configuration, the gap can be minimized by matching the shape of the portion in contact with the upper surface shield main body along the protrusion of the nose and the bulge of the cheek by the concave portion of the nose and the concave portion of the cheek. For this reason, since the droplets are mainly guided downward without escaping upward, it is possible to prevent the droplets from scattering forward and upward and forward, and to shorten the floating time of the droplets in the air. Furthermore, in addition to the combined use with a mask, there is no hindrance to the combined use with eyeglasses, and a certain improvement effect can be expected for the susceptibility of eyeglasses to become cloudy due to exhalation, especially in winter.

[3] Preferably, the nose shield portion is provided with a clip that can be locked to an external member when folded.

According to such a configuration, the nose / mouth shield can be more easily carried by locking the clip in the pocket of clothes in the folded state of the ear hook.

[4] Preferably, the mouth shield portion is in a state where the upper portion is provided on the connecting hinge and is curved so as to bulge forward, and the lower surface shield main body is formed inside the lower surface shield main body and is located in front of the mouth. It is provided with a curved surface curved downward and rearward and both laterally rearward.

According to such a configuration, the mouth shield portion includes a lower surface shield main body curved so as to bulge forward, and a curved surface formed inside the lower surface shield main body and curved laterally rearwardly and downwardly rearward. Even when coughing, the droplets are guided along the curved surface and can be quickly discharged mainly to the lower rear (partly both laterally posterior). Therefore, it is possible to prevent the droplets from scattering forward and upward and forward, and to shorten the floating time of the droplets in the air.

[5] Preferably, the nose shield portion and the mouth shield portion are formed in the shape of a resin plate.
The connecting hinge is provided on either the lower part of the nose shield portion or the upper part of the mouth shield portion, and is provided with a bearing which is partially opened and has elasticity, and the lower portion of the nose shield portion or the mouth shield portion. It is provided with a shaft provided on either one of the upper portions and which is detachably and rotatably supported by the bearing.

According to such a configuration, since the nose shield portion and the mouth shield portion are formed in the shape of a resin plate, maintenance such as washing with water or wiping can be facilitated. By adopting a transparent resin plate for the flip-up and lower mouse shield, it is possible to easily clean the dirt by washing it with water or wiping it off.

Further, the connecting hinge is provided on either the lower part of the nose shield portion or the upper part of the mouth shield portion and is partially opened and has elasticity, and the connecting hinge is either the lower portion of the nose shield portion or the upper portion of the mouth shield portion. Since it is provided on the other side and has a shaft that is detachably supported by the bearing, the mouse shield can be replaced with a new one or a different design.

It suppresses the droplets released from the nose and mouth from scattering forward and upward, and promotes rapid subsidence by mainly guiding them downward and backward, shortening the airborne time of the droplets and shortening the airborne time. , Can be folded to make it easier to carry.

It is a figure explaining the nose mouth shield which concerns on another aspect. It is a figure explaining the nose mouth shield which concerns on further another aspect.

A mode for carrying out the present invention will be described below with reference to the drawings. The drawings conceptually (schematically) show an example of a nose / mouse shield.

As shown in FIG. 1, the nose / mouth shield 10 is a tool for suppressing the spread of droplets of an ear-nose suspension / flip-up type that covers the upper part and the front of a person's nose and mouth with a shield. The nose / mouth shield 10 is formed in a resin plate shape (thin wall shape) and covers the nose 51 to the cheek 52 of a person (see FIG. 4 (B)), and the nose shield portion 20 and the lower portion of the nose shield portion 20. It is provided with a connecting hinge 30 provided, and a mouth shield portion 40 provided on the nose shield portion 20 so as to be rotatable in the vertical direction via the connecting hinge 30 and covering the front of the mouth 54.

Next, the nose shield portion 20 will be described.
The nose shield portion 20 has an upper surface shield main body 21 whose upper portion is in contact with the nose (nose bridge portion) 51 and cheek (cheek portion) 52 and is inclined forward downward, and both sides of both laterally curved portions 27 continuous with the upper surface shield main body 21. The portion is provided with an ear hook portion 23 that is foldably provided via a hinge 22 and is hung on the ear 53. The hinge 22 can be bent by forming a connecting portion between both laterally curved portions 27 and the ear hook portion 23 continuous with the upper surface shield main body 21 as a fragile portion of resin. The hinge 22 is not limited to the fragile portion of the resin, and may have a so-called hinge structure using a shaft. Further, in order to cope with individual differences in facial shape, a vertically movable structure for adjustment may be added behind both buccal side covering portions 23a.

The upper surface shield body 21 is formed with a nasal recess 24 that is recessed along the shape of the nose 51 at a portion in contact with the upper nose 51, and a nasal side convex portion 25 that protrudes along the shape between the nose 51 and the cheek 52. A cheek recess 26 that is formed and is recessed along the shape of the cheek 52 is formed in a portion in contact with the upper cheek 52, and a laterally curved portion 27 that is curved along the lateral roundness of the cheek 52 is formed.

Next, the ear hook portion 23 will be described.
As shown in FIGS. 1 and 2 (A), the ear hook portion 23 is a vine (temple) in general eyeglasses, is connected to a hinge 22, and is widely formed in the vertical direction to cheek. It includes a buccal side covering portion 23a that covers from the lateral side of the 52 to the vicinity of the base of the ear 53, and a modern 23b that hangs on the ear 53.

Next, the mouse shield portion 40 will be described.
As shown in FIGS. 1, 2 (A) and 2 (B), the mouth shield portion 40 includes a lower surface shield main body 41 whose upper portion is provided on the connecting hinge 30 and is curved so as to bulge forward, and the lower surface shield. It is provided with a curved surface 42 formed inside the main body 41 and curved laterally rearwardly and downwardly rearward while being located in front of the mouth 54. The curved surface 42 is formed with an r that is curved downward and backward with respect to the vertical direction, and an r that is curved laterally and backward with respect to the horizontal direction. Due to this curved surface 42, when a person 50 wearing the nose / mouth shield 10 coughs, for example, droplets are mainly guided to the lower rear (partly to the lateral rear) and diffuse to the front and the upper front of the face. Can be deterred.

Next, the action of the nose / mouth shield 10 in the folded state will be described.
As shown in FIG. 3A, the nose shield portion 20 is provided with a clip 28 that can be locked to an external member when the ear hook portion 23 and the mouth shield portion 40 are folded. The nose / mouth shield 10 can be made compact as a whole by folding the ear hook portion 23 and the mouth shield portion 40. In the embodiment, the clip 28 is provided on the upper part of the nose shield portion 20, but the present invention is not limited to this, and the clip 28 may be provided on the lower part of the nose shield portion 20 or at an arbitrary position of the mouth shield portion 40. ..

As shown in FIG. 3B, the nose / mouth shield 10 is placed in the pocket 61 of the garment 60 with the ear hook portion 23 and the mouth shield portion 40 folded. At this time, by locking the clip 28 on the edge of the pocket 61, the nose / mouth shield 10 can be locked in the pocket 61 and easily carried. Since the nose / mouth shield 10 becomes compact when folded, it can be easily carried by putting it in a pocket of clothes or a gap of a bag, for example.

Next, the operation of the mouse shield 100 according to the comparative example will be described.
As shown in FIG. 4A, the mouse shield 100 of the comparative example has a jaw contact portion 101 that contacts the jaw of the person 50 and a mouth 54 that is formed so as to extend upward and forward from the jaw contact portion 101. It is provided with a resin sheet member 102 that covers the front of the chin, and ear straps 103 provided at both ends in the lateral direction of the chin contact portion 101.

The mouth shield 100 of the comparative example is covered with the seat member 102 in the front and lower parts of the nose 51 and the mouth 54 in the worn state. However, since the upper part of the nose tip is open (structure), when a person coughs or makes a loud voice, droplets are scattered from the upper front open part as shown by the arrow. To do. For this reason, it is possible that the droplets fly up and diffuse in front of the face, and the levitation time until they sink downward is rather long.

Next, the operation of the nose / mouse shield 10 according to the embodiment will be described.
As shown in FIG. 4 (B), the nose / mouth shield 10 of the embodiment covers the nose 51 and the upper front and the front of the mouth 54 in a worn state. When a person coughs or makes a loud voice, the droplets are guided and discharged from the lower open portion mainly by the curved surface 42 of the mouse shield portion 40 toward the lower rear as shown by the arrow, and are swift. Sink to. For this reason, the droplets quickly move to a lower position, and the levitation time until the droplets sink downward is shortened. Therefore, since the droplets move rapidly in the direction away from the position of the face (head) of the opponent in front, it is possible to prevent the opponent from inhaling the droplets. In the embodiment, the person 50 does not wear glasses, but the present invention is not limited to this, and even when the person 50 wears glasses, the nose / mouth shield 10 can be worn over the person 50. In this case, a step in the recessed direction is provided in the ear hook portion 23 of the nose / mouth shield 10 at a position where the spectacles overlap with the vine, and the vine of the spectacles is overlapped on the recessed step portion to suppress the overall thickness and give a feeling of strangeness. Can be reduced.

Next, the actions of the mouse shields 110 and 120 according to the two comparative examples when eating and drinking will be described.
As shown in FIG. 5A, the mouse shield 110 of the comparative example has a mounting portion 113 attached to the temple 112 of the eyeglasses 111 worn by the person 50, and a shaft portion 114 provided on the mounting portion 113. And a shield portion 115 that is rotatably provided on the shaft portion 114.

The mouse shield 110 of the comparative example is a shield portion 115 whose normal usage state is shown by an imaginary line, and is rotated to the position of the shield portion 115 shown by a solid line when eating or drinking. However, under normal use conditions, the upper front of the mouth is wide open, so when a person coughs or makes a loud voice, part of the droplets scatter from the upper front open part, causing droplets. It is not possible to eliminate the risk that the air will fly up and spread in front of the face and the airborne time until it sinks downward will be long. Further, when eating or drinking, it is necessary to rotate the shield portion 115 close to the head, which is troublesome. Further, the mouse shield 110 remains in a large form even when not in use, which is inconvenient to carry.

As shown in FIG. 5 (B), the mouse shield 120 of the following comparative example is a temple (hereinafter referred to as a vine) 121 hung on both ears 53, bypassing the front of the face of the person 50, and a vine. The nose support member 122 provided to extend rearward from the front central portion of 121 and supported by the nose, the upper shield 123 provided on the vine 121 and formed in a crescent shape, and the vine 121 near the face of the upper shield 123. It includes a shaft portion 124 provided, and a shield portion 125 rotatably provided on the shaft portion 114.

In the mouse shield 120 of the comparative example, the shield portion 125 is arranged in front of the mouth under normal use conditions, and the shield portion 125 is rotated upward when eating or drinking. However, under normal use, there is a large gap between the upper shield and the nose and cheeks, so when a person coughs or makes a loud voice, part of the droplets will come out from the gap upwards. It is not possible to eliminate the risk that the levitation time will be long until the droplets fly up and forward on the face and sink downward. Further, when eating or drinking, the entire shield portion 125 is rotated around the shaft portion 124 on the face side to the vicinity of the head, which is large and troublesome. Further, the mouse shield 120 remains in a large form even when not in use, which is inconvenient to carry.

Next, the action of the nose mouth shield 10 according to the embodiment when eating and drinking will be described.
As shown in FIG. 5C, in the nose / mouth shield 10 of the embodiment, when eating or drinking, the mouse shield portion 40 is rotated upward from the connecting hinge 30 and flipped up, so that the mouse is viewed from the front of the mouth 54. You can eat and drink while avoiding the shield portion 40. Of the shields of the nose / mouse shield 10, the upper half is the nose shield portion 20, and the substantially lower half is the mouse shield portion 40. Of these, only the mouse shield portion 40 is rotated and flipped up, so that the movement is performed. The range is small and the troublesomeness when eating and drinking can be reduced.

In the embodiment, the connecting hinge 30 is a fragile portion of the resin, but a so-called friction hinge using a shaft may be used, and if it is a friction hinge, the mouse shield portion 40 is rotated and flipped up. Can be held by hand, which can further reduce the annoyance when eating and drinking and improve usability. In addition, by making the material transparent, it is convenient not only for facial expressions but also for conversations at home and presentations in front of a large number of people.

Further, in the nose / mouse shield 10 of the embodiment, the splashing / spreading (diffusion) of droplets during conversation during eating and drinking can be further improved by simply rotating / flipping up / down the mouse shield portion 40 while wearing the main body. It is possible to easily (easily) suppress it without causing a time delay.

Next, the nose / mouse shield 100 according to another aspect will be described. The same configuration as in FIG. 1 will be referred to and a description thereof will be omitted.
As shown in FIG. 6, the nose / mouth shield 10 includes an ear strap 29 on the ear hook 23. The ear strap 29 has elasticity like rubber and can be easily hung on the ear 53 (see FIG. 4B). Further, even the person 50 wearing glasses can easily hang the ear strap 29 on the ear 53 without disturbing the modern 23b.

Next, the nose / mouse shield 100 according to still another aspect will be described.
As shown in FIGS. 7 (A) and 7 (B), the nose / mouse shield 10 is provided with a detachable mouse shield portion 40 from the nose shield portion 20 via a connecting hinge 30. Specifically, the connecting hinge 30 includes a bearing 31 provided below the nose shield portion 20 and having elasticity while being partially opened, a support portion 32 provided above the mouth shield portion 40, and the support portion. A shaft 33 provided on the 32 and detachably supported by the bearing 31 is provided.

The bearing 31 has elasticity, and the shaft 33 can be attached to and detached from the open portion of the bearing 31 by bending the bearing 31. Thereby, for example, it can be replaced with a heart-shaped mouse shield portion 40, and by freely exchanging with a different mouth shield portion 40 having a design, it is possible to provide diversity at a low price.

Next, the actions and effects of the nose / mouse shield 10 described above will be described.
In the embodiment of the present invention, since the nose shield portion 20 includes the upper surface shield main body 21 whose upper portion is in contact with the nose 51 and the cheek 52 and is inclined forward downward, the front of the mouth 54 is covered with the mouth shield portion 40. The upper front of the nose 51 can be covered with the upper surface shield main body 21 of the nose shield portion 20, and it is possible to prevent the droplets released from the nose 51 and the mouth 54 from scattering forward and upward.

Further, since the upper portion of the upper surface shield main body 21 is in contact with the nose 51 and the cheek 52 and is inclined forward downward, even if the wearer 50 coughs, the droplets will be collected from the upper surface shield main body 21 and the nose and cheeks. It hardly comes out from between, and is guided downward along the upper surface shield body 21 that is inclined forward and the front mouth shield portion 40, and is swiftly below the mouth 54 (partly in both lateral directions). ) And sinks. This means that by changing the direction of the energy that the droplets try to disperse forward, the droplets directly reach the vicinity of the opponent's face (head) in front of them, both spatially and spatially. , It is a deterrent in terms of time. Therefore, it is possible to prevent the droplets from diffusing and floating near the face (head) of the other party, and to shorten the floating time of the discharged droplets in the air.

Further, since the ear hook portion 23 is provided on both sides of the upper surface shield main body 21 so as to be foldable, the ear hook portion 23 can be folded to make it compact when not attached, and can be easily carried by putting it in a pocket 61 or the like, for example. Can be done. Furthermore, when eating or drinking, if the mouse shield portion 40 is rotated upward from the connecting hinge 30 and flipped up with the nose / mouth shield 10 attached, the mouth 54 can be opened without removing the nose / mouth shield 10 itself. Can carry food.

Further, in the embodiment of the present invention, the nose recess 24 and the cheek recess 26 can minimize the gap by matching the shape of the portion in contact with the upper surface shield main body 21 along the protrusion of the nose 51 and the bulge of the cheek 52. .. Therefore, since the droplets are hardly scattered upward and are efficiently guided downward, it is possible to prevent the droplets from scattering forward and upward and forward, and to shorten the floating time of the droplets in the air. Further, in addition to the combined use with a mask, there is no hindrance to the combined use with eyeglasses, and a certain degree of suppressing effect can be expected especially in winter and the easiness of fogging of eyeglasses due to exhalation.

Further, in the embodiment of the present invention, the nose / mouth shield 10 can be more easily carried by locking the clip 28 into the pocket 61 of the garment 60 with the ear hook portion 23 folded.

Further, in the embodiment of the present invention, the mouth shield portion 40 includes a lower surface shield main body 41 that is curved so as to bulge forward, and a curved surface 42 that is formed inside the lower surface shield main body 41 and is curved downward and rearward and both laterally rearward. , So even if you cough, the droplets are guided along the curved surface 42, and are quickly discharged to the lower rear (partly to the lateral rear) and sink. Therefore, it is possible to prevent the droplets from scattering forward and upward and forward, and to shorten the floating time of the droplets in the air.

Further, in the embodiment of the present invention, since the nose shield portion 20 and the mouth shield portion 40 are formed in the shape of a resin plate, maintenance such as washing with water or wiping can be facilitated. By adopting a transparent resin plate for the flip-up and lower mouse shield, it is possible to easily clean the dirt by washing it with water or wiping it off.

Further, the connecting hinge 30 is provided on either the lower portion of the nose shield portion 20 or the upper portion of the mouth shield portion 40 and is partially opened and has elasticity, and the lower portion of the nose shield portion 20 or the mouth shield. Since the shaft 33 provided on one of the upper portions of the portion 40 and is detachably supported by the bearing 31 is provided, the mouth shield portion 40 can be replaced with a new one or a different design. be able to.

As mentioned above, the mouse shield has been used as an auxiliary tool that plays a part in the mask function in response to the need to reduce the amount of droplets attached to the airway and the amount of suction as much as possible. .. Its main function is to change the direction of the energy scattered forward of the droplets emitted by coughing, sneezing, or vocalization, so that the droplets fly directly to the vicinity of the opponent's face (head) in front of them. Although it is limited in that it is spatially suppressed or delayed in time, it is often used because it has the advantage of not obscuring the mouth like a mask.

With the conventional mouse shield, the rubber cord between the ear and the chin and the support base method give a slight feeling of oppression, and the frequent attachment / detachment operation is a little troublesome, so it is inconvenient to use when eating and drinking like a mask. there were. In addition, it is possible that the released droplets are scattered above and forward on the face, and the floating time in the air until the droplets sink downward is considered to be long, which is a sufficient function for the purpose of preventing the diffusion of droplets. Is hard to say. In addition, the existing products with ear / nose suspension / flip-up / lowering functions have disadvantages such as being large and unsuitable for carrying.

In this respect, in addition to the above-mentioned actions and effects, the present invention is advantageous in suppressing the scattering and spread of droplets, especially when eating or drinking or talking with people close to home or at home. It is easy to handle and can be expected to have a certain effect even when used alone under limited conditions as a substitute for a part of the mask function. However, the overall mask function cannot be replaced in the first place, and basically, as a tool for reinforcing and improving the weaknesses of the mask function, it is expected that the combined use with the mask will synergistically improve the infection prevention effect.

In the embodiment, the material of the nose / mouth shield 10 is made of resin, but the material is not limited to this, and may be made of metal, paper, or the like.

Further, in the embodiment, the nose / mouth shield 10 is made transparent, but the design is not limited to this, and the design may be improved by coloring such as white, black, and blue, and adding a pattern or a pattern.

That is, the present invention is not limited to the examples as long as the actions and effects of the present invention are exhibited.

The nose / mouth shield of the present invention is suitable as a tool that covers the upper part and the front of a person's nose and mouth and suppresses the scattering / spreading of spouting droplets.
