Description

本考案は、マスクに関する。 The present invention relates to a mask.

インフルエンザや風邪の予防、花粉症対策などのためにマスクを着用するが、スポーツなどで口を大きく動かした際に、着用位置のずれが生じやすく、着用者が置かれている状況によっては直ちにマスクのずれを直すことができずに、鼻孔や口が覆われていない状態が一定時間続いてしまうという事態が発生する。 Wear a mask to prevent influenza and colds, prevent pollinosis, etc., but when you move your mouth a lot in sports, the position of the mask tends to shift, and depending on the situation where the wearer is placed, the mask is immediately worn. A situation occurs in which the nostrils and mouth are not covered for a certain period of time without being able to correct the deviation.

そこで、マスクが着用位置からずれるのを防止するため、様々なマスクが提案されている。
例えば、上下方向に広がることが可能なプリーツが形成されたマスク本体と、前記マスク本体を顔に装着できるように前記マスク本体の左右の側端縁部に装着紐を備えたプリーツマスクにおいて、前記マスク本体の内側を通る固定紐と、前記マスク本体の上縁側の左右の角部付近に、前記固定紐に引っ掛かる紐引掛り部とを有し、前記固定紐に左右の前記紐引掛り部が引っ掛かったことを特徴とするずれ防止マスクが提供されている（特許文献１を参照）。 Therefore, various masks have been proposed in order to prevent the mask from shifting from the wearing position.
For example, in a mask body having pleats that can be spread in the vertical direction and a pleated mask having attachment strings on the left and right side edge portions of the mask body so that the mask body can be attached to the face. It has a fixing string that passes through the inside of the mask body and a string hooking portion that is hooked on the fixing string near the left and right corners on the upper edge side of the mask body, and the left and right string hooking portions are attached to the fixing string. An anti-slip mask characterized by being caught is provided (see Patent Document 1).

しかしながら、従来技術では、マスクがずれるのを防止することができても、呼吸に対する負荷が解消されず、運動している時や暑い時に長時間マスクを着用し続けることが困難になるという問題が生じる。
そこで、呼吸負荷を少なくするために薄い伸縮性が高い素材を採用した場合は、顔とマスクの間の通気のための空間が小さくなるために、マスクが口に密着してしまう事が多く、むしろ呼吸負荷が大きくなるという問題がある。
さらに、状況によっては口の中にマスク生地を噛みこんでしまうことによる不快さや、肌に密着する面積が大きいために汗で濡れやすくなるという問題も生じる。
そこで、本考案の目的は、着用位置のずれが生じにくく、呼吸負荷を改善して息苦しさを感じることなく快適に着用することができるマスクを提供することにある。 However, in the prior art, even if the mask can be prevented from shifting, the load on breathing is not eliminated, and it becomes difficult to keep wearing the mask for a long time when exercising or when it is hot. Occurs.
Therefore, when a thin and highly elastic material is used to reduce the respiratory load, the space for ventilation between the face and the mask becomes small, so the mask often sticks to the mouth. Rather, there is a problem that the respiratory load increases.
Further, depending on the situation, there may be problems such as discomfort caused by biting the mask cloth into the mouth and easy getting wet with sweat due to the large area in contact with the skin.
Therefore, an object of the present invention is to provide a mask that is less likely to be displaced from the wearing position, improves the respiratory load, and can be comfortably worn without feeling suffocating.

上記の課題を解決するために、請求項１記載の考案は、着用者の鼻から顎にかけての顔面の下部を覆うマスクであって、上端縁の中央は前記鼻と接するが、下端縁の中央は前記顎の前方に位置して口周辺とは接しないように立体状に形成された前面部と、前記下端縁から前記顎に向かって略水平方向に張り出している略二等辺三角形の布地であって、前記略二等辺三角形の二等辺の部分が前記前面部の下端縁の中央から左右両端部付近までと結合している平面下部と、前記下端縁の左右両端部を連結する顎下を通す紐状の伸縮性材料により形成されている顎下紐部と、前記顔面に装着するために耳に係止される左右一対の耳掛け部を備え、外力が加えられても形状を維持するように、前記前面部の縦中心線上の部分、及び前記前面部の周縁部分が補強されていることを特徴とする。 In order to solve the above problems, the device according to claim 1 is a mask that covers the lower part of the face from the wearer's nose to the chin, and the center of the upper end edge is in contact with the nose, but the center of the lower end edge. Is a substantially isosceles triangular fabric that is located in front of the chin and is formed in a three-dimensional shape so as not to come into contact with the periphery of the mouth, and extends substantially horizontally from the lower end edge toward the chin. The lower part of the plane where the isosceles portion of the substantially isosceles triangle is connected from the center of the lower end edge of the front surface to the vicinity of the left and right ends, and the submandibular region connecting the left and right ends of the lower end edge. It has a submandibular cord part formed of a string-shaped elastic material through which it passes, and a pair of left and right ear hooks that are locked to the ears for attachment to the face, and maintains its shape even when an external force is applied. As described above, the portion on the vertical center line of the front surface portion and the peripheral edge portion of the front surface portion are reinforced.

請求項２記載の考案は、前記補強は強度のある生地を縫い込むこと、または可撓性を有する芯材を埋め込むことによってなされていることを特徴とする。 The invention according to claim 2 is characterized in that the reinforcement is made by sewing a strong fabric or embedding a flexible core material.

請求項３記載の考案は、前記補強がされている前記前面部の縦中心線上の部分は、前記前面部の上端縁の中央から前記着用者の人中の前方に当たる位置までの部分、または前記前面部の上端縁の中央から前記前面部の下端縁の中央までの部分であることを特徴とする。 According to the third aspect of the present invention, the reinforced portion of the front surface portion on the vertical center line is a portion from the center of the upper end edge of the front surface portion to a position corresponding to the front of the philtrum of the wearer, or the portion described above. It is a portion from the center of the upper end edge of the front surface portion to the center of the lower end edge of the front surface portion.

第１に、マスク内の鼻孔及び口周辺に空間を作り出す立体的な構造としたことにより、呼吸負荷を改善して息苦しさを感じることなく快適にマスクを着用することができるという効果が発生する。
第２に、マスクが着用者の肌に密着する部分が少ないので、体温上昇や汗による濡れが減少し乾燥を早めるという効果が発生する。 First, the three-dimensional structure that creates space around the nostrils and mouth inside the mask has the effect of improving the respiratory load and allowing the mask to be worn comfortably without feeling stuffy. ..
Secondly, since there are few parts where the mask comes into close contact with the wearer's skin, the effect of increasing body temperature and reducing wetting due to sweat and accelerating drying occurs.

The side corresponding to the upper side of the wearer's face is referred to as the upper side, and the side corresponding to the lower side is referred to as the lower side.

本考案は、着用者の鼻から顎にかけての顔面の下部を覆うマスクに関するものである。
図１は、本考案に係るマスクを外側から示した説明図であり、図２は、本考案に係るマスクを下方から示した説明図である。
図１及び図２に示すように、本考案に係るマスクは、上端縁の中央は着用者の鼻と接するが、下端縁の中央は着用者の顎の前方に位置して口周辺とは接しないように立体状に形成された前面部１と、前面部１の下端縁から顎に向かって略水平方向に張り出している略二等辺三角形の布地であって、略二等辺三角形の二等辺の部分が前面部１の下端縁の中央から左右両端部付近までと結合している平面下部２と、前面部１の下端縁の左右両端部を連結する顎下を通す紐状の伸縮性材料により形成されている顎下紐部３と、着用者の顔面に装着するために耳に係止される左右一対の耳掛け部４を備える。 The present invention relates to a mask that covers the lower part of the face from the wearer's nose to the chin.
FIG. 1 is an explanatory view showing the mask according to the present invention from the outside, and FIG. 2 is an explanatory view showing the mask according to the present invention from below.
As shown in FIGS. 1 and 2, in the mask according to the present invention, the center of the upper end edge is in contact with the wearer's nose, but the center of the lower end edge is located in front of the wearer's chin and is in contact with the periphery of the mouth. It is a fabric of a substantially isosceles triangle that is formed in a three-dimensional shape so as not to be formed, and a fabric of a substantially isosceles triangle that projects substantially horizontally from the lower end edge of the front portion 1 toward the chin, and is an isosceles triangle of approximately isosceles. With a string-shaped elastic material that passes under the chin that connects the left and right ends of the lower end edge of the front surface 1 and the lower surface 2 whose portion is connected from the center of the lower end edge of the front surface 1 to the vicinity of the left and right ends. It includes a formed submandibular cord portion 3 and a pair of left and right ear hook portions 4 that are locked to the ears for attachment to the wearer's face.

前面部１は、上端縁の中央は着用者の鼻と接するが、下端縁の中央は着用者の顎の前方に位置して口周辺とは接しないように立体状に形成されている。着用者の顎の前方であれば、顎の前方斜め下でも良い。
着用時に前面部１の内側と着用者の鼻孔、口及び顎は接触せず、マスク内の口周辺に空間を作り出す構造となっている。
マスク内の鼻孔及び口周辺の部分に空間が形成されるため、マスクを装着しても呼吸が楽であり、息苦しさを感じることなく快適に着用することができる。
前面部１は、特に材料を限定せず、例えば、乾式不織布、湿式不織布、スパンメルト不織布、スパンレース不織布等の不織布類、化合繊製織物、ニット類など、様々なものを用いることができる。
なお、下端縁の両端部に、顎下紐部３及び耳掛け部４を結び直すことができるように環状部分が形成されていても良い。同様に、上端縁の両端部も、耳掛け部４を結び直すことができるように環状部分が形成されていても良い。 The front surface portion 1 is formed in a three-dimensional shape so that the center of the upper end edge is in contact with the wearer's nose, but the center of the lower end edge is located in front of the wearer's chin and is not in contact with the periphery of the mouth. As long as it is in front of the wearer's chin, it may be diagonally below the front of the chin.
The structure is such that the inside of the front surface 1 does not come into contact with the wearer's nostrils, mouth and chin when worn, and a space is created around the mouth inside the mask.
Since spaces are formed in the nostrils and around the mouth inside the mask, it is easy to breathe even when the mask is worn, and it can be worn comfortably without feeling stuffy.
The material of the front surface portion 1 is not particularly limited, and various materials such as non-woven fabrics such as dry non-woven fabric, wet non-woven fabric, spunmelt non-woven fabric, and spunlace non-woven fabric, synthetic fiber woven fabric, and knit fabric can be used.
An annular portion may be formed at both ends of the lower end edge so that the submandibular cord portion 3 and the ear hook portion 4 can be reconnected. Similarly, both ends of the upper end edge may also be formed with annular portions so that the ear hook portion 4 can be reconnected.

前面部１は、外力が加えられても形状を維持するように、前面部１の縦中心線上の部分、及び前面部１の周縁部分が補強されている。補強部分が立体的な構造のマスクの支持架としての役割をもち、着用者の口の前に形成されるマスク内の空間を保持するためである。
補強がされている部分について、さらに詳しく説明する。
第１に、前面部１の上端縁を二等分する縦中心線上の部分を補強している。より具体的には、前面部１の上端縁の中央から着用者の人中の前方に当たる位置までの部分、または前面部１の上端縁の中央から前面部１の下端縁の中央までの部分である。立体的な形状を維持して、鼻尖の下から顎にかけてマスクが口周辺に密着しないようにして、マスク内の空間を保持するためである。
図１及び図３は、前面部１の上端縁の中央から着用者の人中の前方に当たる位置までの部分を補強している場合を示している。
前面部１の上端縁の中央から着用者の人中の前方に当たる位置までの部分、または前面部１の上端縁の中央から前面部１の下端縁の中央までの部分のいずれであっても、補強がされている部分の一部は着用者の鼻梁に接する。
第２に、前面部１の両側縁を補強している。立体的な形状を維持するため前面部１の左右の両側縁を強化し、耳にかけるゴムの張力で両側縁が縮み、両側縁の下方が上がるのを防ぐことで立体的構造を維持し空間を保持するためである。
第３に、前面部１の下端縁を補強している。前面部１の下端縁中央付近が着用者の顎に接したりしてマスク内の空間が狭くならないようにするためである。
第４に、前面部１の上端縁を補強している。前面部１の上端縁中央が着用者の鼻梁に位置するのを維持するためである。
補強の方法としては、補強部分に強度のある生地を縫い込む方法、あるいは補強部分に可撓性を有する芯材を埋め込む方法など様々な方法が可能である。可撓性を有する芯材としては、ワイヤーなど様々なものが使用可能である。
このように形成したことにより、前面部１が着用者の肌と接するのは、上端縁及び両側縁付近の内側、上端縁中央から着用者の鼻尖の前までの補強部分の内側などである。 The front surface portion 1 is reinforced with a portion on the vertical center line of the front surface portion 1 and a peripheral portion of the front surface portion 1 so as to maintain its shape even when an external force is applied. This is because the reinforcing portion serves as a support rack for the mask having a three-dimensional structure and holds the space inside the mask formed in front of the wearer's mouth.
The reinforced part will be described in more detail.
First, the portion on the vertical center line that bisects the upper end edge of the front surface portion 1 is reinforced. More specifically, in the portion from the center of the upper end edge of the front surface portion 1 to the position corresponding to the front of the philtrum of the wearer, or the portion from the center of the upper end edge of the front surface portion 1 to the center of the lower end edge of the front surface portion 1. is there. This is to maintain the three-dimensional shape and prevent the mask from sticking to the periphery of the mouth from under the tip of the nose to the chin to maintain the space inside the mask.
1 and 3 show a case where the portion from the center of the upper end edge of the front surface portion 1 to the position corresponding to the front of the philtrum of the wearer is reinforced.
Either the portion from the center of the upper end edge of the front surface 1 to the position corresponding to the front of the wearer's philtrum, or the portion from the center of the upper end edge of the front surface 1 to the center of the lower end edge of the front surface 1. Part of the reinforced part touches the wearer's bridge of the nose.
Secondly, both side edges of the front surface portion 1 are reinforced. In order to maintain the three-dimensional shape, the left and right edges of the front part 1 are strengthened, and the tension of the rubber applied to the ears causes the edges to shrink, preventing the lower edges from rising to maintain the three-dimensional structure and space. This is to hold.
Thirdly, the lower end edge of the front surface portion 1 is reinforced. This is to prevent the space inside the mask from becoming narrow due to the vicinity of the center of the lower end edge of the front surface portion 1 coming into contact with the wearer's chin.
Fourth, the upper end edge of the front surface portion 1 is reinforced. This is to maintain the center of the upper end edge of the front surface portion 1 located on the nose bridge of the wearer.
As a method of reinforcement, various methods such as a method of sewing a strong cloth into the reinforcing portion and a method of embedding a flexible core material in the reinforcing portion are possible. As the flexible core material, various materials such as wires can be used.
Due to this formation, the front surface portion 1 comes into contact with the wearer's skin on the inside near the upper end edge and both side edges, the inside of the reinforcing portion from the center of the upper end edge to the front of the wearer's nose tip, and the like.

図３は、本考案に係るマスクを下方内側から示した説明図である。図３に示すように、平面下部２は、前面部１の下端縁から着用者の顎に向かって略水平方向に張り出している略二等辺三角形の布地であって、略二等辺三角形の二等辺の部分が前面部１の下端縁の中央から前面部１の下端縁の左右両端部付近までと結合している。そして、略二等辺三角形の頂点の部分が前面部１の下端縁の中央で結合している。
前面部１の下端縁の中央付近が顎に接触せずに顎の前方方向に出ていることによって生じた空いた部分を塞ぐために設けられるものである。前面部１だけではマスク内の空間の下方が開口してしまい飛沫が落下するため、平面下部２によって飛沫が落下するのを抑止している。
平面下部２の布地は、綿布など様々な布地が使用可能である。 FIG. 3 is an explanatory view showing the mask according to the present invention from the lower inside. As shown in FIG. 3, the lower portion 2 of the plane is a substantially isosceles triangular fabric that projects substantially horizontally from the lower end edge of the front surface portion 1 toward the wearer's jaw, and is an isosceles triangle of the substantially isosceles triangle. Is connected from the center of the lower end edge of the front surface portion 1 to the vicinity of the left and right ends of the lower end edge of the front surface portion 1. Then, the apex portion of the substantially isosceles triangle is connected at the center of the lower end edge of the front surface portion 1.
It is provided to close the vacant portion created by the vicinity of the center of the lower end edge of the front surface portion 1 protruding in the front direction of the chin without contacting the chin. Since the lower part of the space in the mask is opened only by the front surface portion 1 and the droplets fall, the lower surface 2 prevents the droplets from falling.
As the cloth of the lower part 2 of the plane, various cloths such as cotton cloth can be used.

図３に示すように、顎下紐部３は、前面部１の下端縁の左右両端部を連結する着用者の顎下を通す紐状の伸縮性材料により形成されている。
顎下紐部３は、着用者の下顎に引っ掛かる伸縮性のあるもので形成されている。顎下を通す伸縮性材料からなる紐状の顎下紐部３を装着することで、前面部１の両側縁下が耳側にずれてマスク内の空間が狭くなることを防いでいる。また、運動時にマスクが上にずれることも防ぎ、耳掛け部４によって上の方に引っ張られようとすることを、この顎下紐部３によって阻止している。
また、顎下紐部３により前面部１の両側縁が着用者の頬に当接するようになるので、マスクの側面からの細菌や塵埃の侵入を阻止することにも役立っている。
顎下紐部３は、部分的に着用者の顎下と当接し、ゴム紐からなる紐状体または平織りのゴム紐からなる帯状体のものが使用可能である。
顎下紐部３は、着用者の顎の大きさに合わせて下端縁の左右両端部において結び直すことができるように環状部分が形成されていても良い。 As shown in FIG. 3, the submandibular cord portion 3 is formed of a string-shaped elastic material that passes under the chin of the wearer connecting the left and right end portions of the lower end edge of the front surface portion 1.
The submandibular cord portion 3 is formed of an elastic material that is hooked on the wearer's lower jaw. By attaching the string-shaped submandibular cord portion 3 made of an elastic material that passes under the chin, it is possible to prevent the space under the mask from being narrowed by shifting the lower edges of both sides of the front surface portion 1 toward the ear side. Further, the mask is prevented from being displaced upward during exercise, and the submandibular cord portion 3 prevents the mask from being pulled upward by the ear hook portion 4.
Further, since both side edges of the front surface portion 1 come into contact with the wearer's cheeks due to the submandibular cord portion 3, it is also useful for preventing the invasion of bacteria and dust from the side surface of the mask.
As the submandibular cord portion 3, a string-like body made of a rubber string or a band-shaped body made of a plain-woven rubber string, which partially abuts under the chin of the wearer, can be used.
The submandibular cord portion 3 may be formed with an annular portion so that it can be retied at the left and right ends of the lower end edge according to the size of the wearer's jaw.

耳掛け部４は、マスクを着用者の顔面に装着するために着用者の耳に係止される左右一対のものであり、ゴム紐からなる紐状体または平織りのゴム紐からなる帯状体のものが使用可能である。耳掛け部４は伸縮性の部材からなり、マスクに対して斜め上に引っ張って、着用者の左右の耳に掛けられるようになっている。
なお、前面部１の上端縁及び下端縁の両端部に、耳掛け部４を結び直すことができるように環状部分が形成されていても良い。 The ear hooks 4 are a pair of left and right ear hooks that are locked to the wearer's ears in order to attach the mask to the wearer's face, and are a string-like body made of a rubber cord or a strip-shaped body made of a plain-woven rubber cord. Things are available. The ear hook portion 4 is made of an elastic member, and is pulled diagonally upward with respect to the mask so that it can be hung on the left and right ears of the wearer.
An annular portion may be formed at both ends of the upper end edge and the lower end edge of the front surface portion 1 so that the ear hook portion 4 can be reconnected.

本実施例による効果について、説明する。
第１に、マスク内の鼻孔及び口周辺に空間を作り出す立体的な構造としたことにより、呼吸負荷を改善して息苦しさを感じることなく快適にマスクを着用することができるという効果が発生する。
第２に、マスクが着用者の肌に密着する部分が少ないので、体温上昇や汗による濡れが減少し乾燥を早めるという効果が発生する。
第３に、マスクが着用者の肌に密着する部分が少ないので、顔を化粧した場合でもマスクに化粧が付着するのを少なくすることができるという効果が発生する。
第４に、前面部１の縦中心線上の部分、及び前面部１の周縁部分が補強されているので、マスクが着用位置からずれないという効果が発生する。
第５に、顎下紐部３を設けることで、マスクが上方にずれることや両側に広がることを防止できるという効果が発生する。 The effect of this embodiment will be described.
First, the three-dimensional structure that creates space around the nostrils and mouth inside the mask has the effect of improving the respiratory load and allowing the mask to be worn comfortably without feeling stuffy. ..
Secondly, since there are few parts where the mask comes into close contact with the wearer's skin, the effect of increasing body temperature and reducing wetting due to sweat and accelerating drying occurs.
Thirdly, since there are few parts where the mask is in close contact with the wearer's skin, there is an effect that the makeup can be less likely to adhere to the mask even when the face is made up.
Fourth, since the portion on the vertical center line of the front surface portion 1 and the peripheral portion of the front surface portion 1 are reinforced, the effect that the mask does not shift from the wearing position occurs.
Fifth, by providing the submandibular cord portion 3, the effect of preventing the mask from shifting upward or spreading to both sides occurs.
