Description

The present invention relates to a device for protecting the user's face from contaminants such as waste liquid, body fluid, dust and dirt: a face shield.

Various devices are known for protecting the user's face from contaminants such as body fluids and dust and droplets containing viruses. For example, Patent Document 1 describes an eye shield mask in which a face protection film made of transparent plastic and a mask are integrated with the face protection film. Patent Document 2 describes a surgical mask including a masked covering portion, a fixing portion, a rotating frame, and a transparent cover shield. Further, Patent Document 3 describes a face guard frame provided with a front frame, a vine, and a transparent plastic sheet, which can be worn while wearing glasses.

However, there is room for improvement in these conventional face shields. For example, in the eye shield mask described in Patent Document 1, the adhesion between the mask and the face protection film is weak and it is not easy to put on and take off. There is a problem that it is small and the user cannot secure a good field of view. Although the surgical mask described in Patent Document 2 has a high ability to protect medical staff present at the surgical site, it is expensive due to the large number of parts and is not easy to put on and take off. It is difficult to disseminate it to the nursing staff. The face guard frame described in Patent Document 3 is convenient in that it has a simple structure and can be worn while wearing glasses, but it can be attached and detached when the transparent plastic sheet is thinned to secure the user's field of vision. In this case, it is necessary to carefully hold the transparent plastic sheet and the frame with both hands, and there is still a problem in terms of handleability.

[Face Shield] The face shield of the present invention has a transparent sheet, a frame, and a fixing member. Hereinafter, each component will be described.

[Transparent sheet] The transparent sheet provided in the face shield of the present invention faces the user's face when the face shield of the present invention is worn, and protects the user's face from contaminants such as blood, droplets, and dust. To do. In order to enhance the protective function, it is desirable to construct the transparent sheet with a material having appropriate flexibility and strength. As the material of such a transparent sheet, for example, polystyrene resin, polypropylene resin, polyacrylate resin, polycarbonate resin and the like are used. The thickness of the transparent sheet is appropriately set according to the handleability and strength of the user, and is not particularly limited, but is usually in the range of 0.1 mm or more and 2 mm or less, preferably 0.2 mm or more and 1 mm or less.

The shape of the transparent sheet is not limited as long as it can protect the face of the user and does not interfere with the movement of the user. Usually, as a transparent sheet, a sheet cut into a shape close to a rectangle or an ellipse without sharp corners is used.

[Frame] The frame provided in the face shield of the present invention is in direct contact with the skin of the user when the face shield of the present invention is worn, and holds the transparent sheet so as to face the face of the user. It is desirable that the frame be arranged in a shape and position that does not interfere with the user's field of view. In the present invention, the transparent sheet and the frame are connected to each other at the end of the transparent sheet.

The frame is held by the front frame facing the transparent sheet and the user's face when the face shield of the present invention is worn, and by the user's temporal region when the face shield of the present invention is worn. Has a side frame and is The front frame is typically held on both sides of the user's nose. A preferred form of the front frame is a so-called spectacle nose pad. The side frame held on the user's temporal region may be hung on the user's ear. A preferred form of the side frame is a so-called ear hook portion (vine) of glasses.

The entire frame is held on both sides of the user's nose and the frame surrounding the frame of the user's glasses so that the user can use the face shield of the present invention while wearing glasses ( It is desirable to configure it with a nose pad).

The frame used in the present invention can have a foldable structure. Preferably, the connecting portion between the front frame and the side frame can be bent. More preferably, when the face shield of the present invention is not used, the side frame is folded so as to face the transparent sheet and the front frame. With such a structure, the entire face shield can be stored in a compact shape.

[Fixing member] The fixing member included in the face shield of the present invention connects the transparent sheet and the frame. Preferably, the transparent sheet and the frame are connected by sandwiching both ends of the transparent sheet between the frame and the fixing member. More preferably, holes are provided at both ends of the transparent sheet, and a part of the fixing member penetrates the holes and is connected to the frame so that the frame and the fixing member are connected to both ends of the transparent sheet. The transparent sheet and the frame are connected by sandwiching the portion.

In the face shield of the present invention, the surface of the transparent sheet sandwiched between the frame and the fixing member can be swiveled between the frame and the fixing member. Therefore, the fixing member used in the present invention is fixed to the frame via the transparent sheet by a clip type and / or a screw type without being welded to the transparent sheet.

In the face shield of the present invention, it is possible to limit the range of the above-mentioned turning to prevent the transparent sheet from moving to a position where the face protection of the user is impossible while the face shield of the present invention is worn. preferable. In order to realize such a limited turning motion, for example, holes and notches are provided at both ends of the transparent sheet. In this case, a part of the fixing member penetrates the hole and is connected to the frame, so that the surface of the transparent sheet sandwiched between the frame and the fixing member is between the frame and the fixing member. Then, it turns around the hole as an axis. When the turning progresses and the end of the notch comes into contact with the frame and / or the fixing member, the turning of the transparent sheet is stopped. Therefore, the swivel range of the transparent sheet is limited to the range corresponding to the size of the notch.

In the present invention, since the transparent sheet is swiveled between the frame and the fixing member while being sandwiched between the frame and the fixing member, the user can use a small force, typically with one hand, to rotate the transparent sheet. Can be moved to an appropriate position. Moreover, the transparent sheet stops at the moved position. When the transparent sheet is provided with a hole and a notch, the swivel range of the transparent sheet is limited. Therefore, even if the transparent sheet comes into contact with people or objects in the vicinity, the transparent sheet swirls greatly and the user can use it. It is possible to prevent the state from becoming unprotected. As described above, the fiss shield of the present invention can adjust the position of the transparent sheet according to the usage environment (lighting, wind direction, surrounding people and objects) with a simple operation.

An example of the present invention will be described with reference to the drawings. The shape and arrangement of the members constituting the face shield of the present invention are not limited to the shape and arrangement shown in the drawings.
