Description

[Technical field]

[0001] The present invention relates to a mask and a split face shield consisting of a mask and glasses. [Background technology]

[0002] The new coronavirus (SARS-CoV-2) that was discovered in Wuhan, China in 2019 quickly spread throughout the world, and by the end of 2021, the number of people infected with the new coronavirus worldwide exceeded 280 million. The virus is still mutating, and there is a possibility that it could lead to a sixth wave of infections caused by the omicron type.

[0003] Meanwhile, the Japanese government is encouraging people to wear masks, wash their hands, avoid the "three Cs" (crowded places, close contact, and closed spaces), and get vaccinated to prevent infection. After the COVID-19 pandemic, scholars predict that the impact of COVID-19 will eventually subside to the same level as that of seasonal influenza.

[0004] Non-Patent Document 1, titled "Will the day come when we can take off our masks? Current official recommendations," reports that the highly infectious delta strain spread immediately after the Centers for Disease Control and Prevention (CDC) issued guidance to people who had received two doses of the COVID-19 vaccine that "it is not necessary to wear masks in many places," resulting in a sharp increase in the number of infected people. In response to this, the CDC has updated its guidance to recommend wearing masks again. It recommends that "masks should be worn when indoors in public places." Although the number of new infections in Japan is relatively low compared to other countries, in preparation for the sixth wave, it is recommended that people wash their hands, disinfect their hands, avoid crowds, and wear masks. In the UK, a survey of 4,442 patients with respiratory diseases was conducted to see if they would continue to take the same measures as they do now one year after the end of the coronavirus pandemic, and approximately 50% of the total respondents answered that they would wear masks.

[0005] Masks commonly used by civilians are made of gauze or nonwoven fabric and are intended to prevent the spread of cough and sneeze droplets, pollen, dust, and other particles from entering the body, and are broadly classified into flat, pleated, and three-dimensional shapes. Special-purpose masks used by medical workers include N95 masks, which protect people from outside air containing microorganisms, and surgical masks, which prevent particles containing microorganisms from being emitted by the person wearing the mask from spreading into the air.

[0006] In addition to the masks mentioned above, there are also face shields, which are commonly used to protect the face and eyes from sparks generated when welding or cutting metal at construction sites, as well as by police and the Self-Defense Forces as a non-bulletproof measure, and by medical workers to protect the face from blood and infectious liquids. Recently, however, they are also being used by those in the service industry and on-location program production to prevent the spread of droplets.

[0007] Patent Document 1 proposes a mask which comprises a nose mask body which fits closely to the face and is fitted against the nose area by the tension of the right and left ear hook bodies, and a mouth mask body which has a space piece attached so that it comes into contact with the nostrils and is fitted against the mouth area by the tension of the right and left ear hook elastic bodies, and which is fitted such that the nose mask part is put on first, and then the mouth mask part is put on over the nose mask part.

[0008] Patent Document 2 proposes a mask structure in which a combination board with a special isolation layer function is placed between the bottom of the nostrils and the upper part of the lips around the mouth inside the mask, a special structure that protects only the nose by blocking exposure of the nose area, and a transparent protective face shield with a manual leverage principle is attached to the end of a plate fixed to the ear straps of the mask.

[0009] Both masks make it possible to eat while wearing them; the mask in Patent Document 1 consists of two pieces, a nose mask and a mouth mask, while the mask in Patent Document 2 has a face shield in front of it that can be rotated, but with both masks it is necessary to move the mouth mask or face shield when putting food in the mouth.

[0011] [Non-Patent Document 1] Hurst JR,et al.Thorax.2021 Oct.21;thoraxjnl-2021-217981 Summary of the Invention [Problem to be solved by the invention]

[0012] From the above, it is assumed that even after the COVID-19 pandemic subsides, the percentage of people wearing masks or face guards will remain high, and that in the future, people will continue to eat in silence and take off and put on masks after each bite as a means of preventing infection. However, it is also true that masks easily get dirty when eating out, and many people find it troublesome to put on and take off their masks after each bite. [Means for solving the problem]

[0013] In view of the above problems, the inventor has used his ingenuity to propose a mask that not only allows people to eat easily while wearing the mask, but also prevents droplets from spreading, as well as a split face guard consisting of a mask and glasses.

[0014] In the first embodiment, the mask has a structure in which the frame contacts all or part of the inner peripheral portion of the mask body, and is equipped with a moving means that allows the mask body to slide freely forward or diagonally downward relative to the face when the mask is worn.

[0015] The moving means of the first embodiment is composed of a sliding support attached directly or indirectly to the mask body, a sliding support guide part attached directly or indirectly to the frame and having a hole for passing the sliding support, and a sliding support insertion part, and the sliding support guide part and the sliding support insertion part are fixed. The sliding support is a sliding bar, a sliding plate, a telescopic rod, etc., and the sliding support insertion part has a hole into which the sliding support can be inserted. As an example of another moving means that does not use a sliding support, a method of attaching a rotatable plate attached to the side of the frame and the mask body to the plate (so that it can rotate), or a plate provided with a groove for sliding the mask body attached to the frame and a mask body to which a pin movable relative to the slide groove is fixed can be attached.

[0016] In the second embodiment, the mask has a structure in which the frame contacts the entire or part of the inner peripheral portion of the mask body, and is equipped with a tilting means having a fulcrum at the upper part of the mask body so that the mask can be freely tilted relative to the frame when worn.

[0017] The tilting means of the second embodiment includes a method of fixing the bearing with a hole on the side of the mask body so that the mask body can be tilted freely with respect to the face, a method of connecting the mask body and the frame with a hinge, a method of threading both the hole on the side of the mask body and the hole on the frame and fastening the frame with a screw, etc. In particular, when the mask is fastened with a screw, the mask can be fastened with the screw in a lifted state, so that the lower mask body does not have to be lifted each time when eating, and it also prevents splashes. However, in the second embodiment, when the mask body is tilted, the edge area of ​​the mask body that corresponds to the nose tip may crush the nose, so the shape of the edge area needs to be devised.

[0018] In a third embodiment, the mask body is divided into an upper mask body and a lower mask body at a position below the nose, and when the mask is worn, a frame contacts the entire or part of the inner peripheral portion excluding the divided portion between the upper mask body and the lower mask, and the mask is provided with a moving means for allowing the lower mask body to slide freely forward or diagonally downward relative to the face, and a tilting means for allowing the lower mask body to tilt freely relative to the upper mask body.

[0019] The moving means for the lower mask body part of the third embodiment to be slidable forward or diagonally downward with respect to the face is composed of a sliding support directly or indirectly attached to the lower mask body part, a sliding support guide part having a hole for passing the sliding support directly or indirectly attached to the frame, and a sliding support insertion part, and the sliding support guide part and the sliding support insertion part are fixed in structure. The sliding support is a sliding rod, a sliding plate, a telescopic rod, or the like, and the sliding support insertion part has a hole for inserting the sliding support. As an example of another moving means that does not use a sliding support, a method of attaching a rotatable plate attached to the side of the frame and the lower mask body part to the plate (so that it can rotate), or a plate provided with a groove for sliding the lower mask body part attached to the frame and a lower mask body part to which a pin movable relative to the sliding groove is fixed can be attached.

[0020] Next, the tilting means of the third embodiment includes a method of fastening a fixing part for bearing having a hole on the side of the lower mask body so that the lower mask body has a fulcrum at the top of the lower mask body and can be tilted freely relative to the face, a method of connecting the lower mask body and the frame with a hinge, a method of connecting the upper mask body and the lower mask body with a hinge, etc. Also, it is possible to thread the hole on the side of the lower mask body and the hole in the frame and fasten them with a screw.

[0021] In a fourth embodiment, the mask has a structure in which the frame contacts the entire or part of the inner peripheral portion of the mask main body when the mask is worn, and is equipped with a moving means for allowing the mask main body to slide freely forward or diagonally downward relative to the face when the mask is worn, and a tilting means having a fulcrum at the upper part of the mask main body and allowing it to tilt freely relative to the frame.

[0022] The moving means of the fourth embodiment may have the same mechanism as the moving means of the first embodiment, and the tilting means may have the same mechanism as the second embodiment.

[0023] In the third embodiment, the reason for using both the moving means and the tilting means for allowing the lower mask body part to slide freely forward or diagonally downward with respect to the face is that if the lower mask body is tilted alone, it will collide with the upper mask body part and cannot be tilted, so by once moving the lower mask body part forward or diagonally downward, the lower mask body part can be tilted. In the fourth embodiment, since the upper side surface of the mask body part may crush the nose due to the tilting of the mask body part, by once moving the lower mask body part forward or diagonally downward, it is possible to avoid crushing the nose even if the lower mask body part is tilted.

[0024] By attaching a packing made of a material such as resin, rubber or urethane sponge to the inner periphery or near the periphery of the mask body, or to the frame that contacts the inner side of the mask body, it is possible to improve the adhesion between the mask body and the frame. Also, by providing the packing on the frame surface that contacts the face, the adhesion is improved.

[0025] In the glasses of the present invention, the shape of the top of the mask in the first to fourth embodiments matches the shape of the bottom of the glasses, and by placing the glasses on the top of the mask, a split face guard is formed.

[0026] The eyeglasses have a removable packing attached to the inner periphery of the frame, and the thickness of the eyeglasses can be made the same as that of the mask to improve the appearance. As for the method of wearing the eyeglasses, when the mask of the present invention is worn by the temples or ears, a headband is used like goggles, and when the mask of the present invention is worn as a headband, the eyeglasses of the present invention are preferably worn by the temples or ears. Effect of the Invention

[0027] According to the present invention, not only can you easily eat while wearing the mask, but it also helps prevent viral infections, droplets, and pollen. Furthermore, by moving the mask body or the lower mask body forward, you can breathe more easily as you are relieved from the feeling of breathlessness. [Brief description of the drawings]
