Description

The present invention relates to a mask-type shield that can cover the user's mouth and nostrils and can eat and drink without removing the shield.

Conventionally, a cloth face guard for on-site work is attached to the work helmet in advance, and after wearing the helmet, the left and right sides of the face guard for on-site work are fastened at the front part of the face to make the face below the eyes. A face guard for field work that can be covered is disclosed (see, for example, Patent Document 1 (see, paragraph [0004], paragraph [0006], FIGS. 1 to 3)). In this face guard, the face guard is attached so that the back of the head band of the work helmet is wrapped with two horizontally long magic tapes (registered trademarks) that are spaced vertically and extend horizontally, and both ends in the longitudinal direction of the face guard are attached. By attaching and detaching two vertically elongated magic tapes (registered trademarks) provided on each of the faces, the front part of the face can be opened and closed.

In the field work face guard configured in this way, the face guard can be easily attached to the back of the head band of the work helmet with two horizontally long magic tapes (registered trademarks). In addition, by attaching and detaching two vertically long magic tapes (registered trademarks) at both ends of the face guard, it is possible to open and close the front part of the face, making it easy to eat and smoke.

JP-A-2007-131997

However, the face guard for on-site work shown in Patent Document 1 has a problem that the face guard cannot be used unless a work helmet having an occipital band is worn. In particular, in recent years, infectious diseases (for example, COVID-19 of new coronavirus pneumonia) have become very prevalent, and it is possible to eat without removing the face guard for on-site work shown in Patent Document 1 above. Even if a medical worker wants to use a face guard, there is a problem that it is difficult to use it because it is mandatory to wear a work helmet. Further, in the face guard for field work shown in Patent Document 1, when the two vertically long magic tapes (registered trademarks) at both ends of the face guard are separated from each other in order to eat or the like, the face guard is placed on the back of the user. There was also the problem that it took time and effort to attach the two vertically long Velcro tapes (registered trademarks) at both ends of the face guard to each other because it hangs down.

<First Embodiment>
As shown in FIGS. 1, 3 and 10, the mask type shield 10 includes a shield main body 12 that covers the mouth 11a and the outer nostril of the user 11, a frame 13 to which the shield main body 12 is attached, and both ends of the frame 13. It includes a pair of linear bodies 14 and 15 that are connected and hung on the ears 11b of the user 11. In this embodiment, the shield body 12 is preferably formed of a transparent plastic film. Specifically, the shield main body 12 is preferably formed of a transparent plastic film such as polypropylene or polyethylene terephthalate having flexibility having a thickness of about 0.1 mm to 0.3 mm. Here, by forming the shield main body 12 with a transparent plastic film, the facial expression of the user 11 of the mask type shield 10 can be shown to the other party. Further, the shield main body 12 is formed in a substantially trapezoidal shape whose upper side is longer than the lower side when viewed from the front, and a pair of projecting pieces 12a and 12b extending diagonally upward and in a direction away from each other are projected from both ends of the upper edge thereof. A pair of circular through holes 12c and 12d are formed in these projecting pieces 12a and 12b, respectively. Further, on the upper edge of the shield main body 12, an eaves portion 12e projecting rearwardly and rearwardly from the upper part of the front edge to the upper part of the side edge is formed.

In order to produce the shield main body 12, first, the shield main body 12 is punched out from a transparent plastic film into a developed shape (FIG. 6A), and then vertically in the center of the shield main body 12 in the unfolded state. Along with forming the extending first fold 12f, a second fold 12g extending in the lateral direction is formed in order to form a portion to be the eaves portion 12e. Reference numeral 12h in FIG. 6A is a notch formed in the center of the portion to be the eaves portion 12e extending in the vertical direction. Next, the portion of the shield main body 12 in the unfolded state that becomes the eaves portion 12e is bent at a substantially right angle at the second fold 12g to form the eaves portion 12e, and is bent at a substantially right angle at the first fold 12f (FIG. 6). (B) and FIG. 7). This completes the shield body 12.

On the other hand, the frame 13 is connected to the nose back locking portion 13a which is locked to the nose back 11c of the user 11 and extends to the left and right, and the left and right ends of the nose back locking portion 13a, and is connected to the left and right cheeks of the user 11. It has a pair of legs 13b, 13c extending downward along 11d (FIGS. 1, 3 and 9). Further, a collar portion 13d projecting forward and front side is formed from the lower part of the front edge of the frame 13 to the lower part of the side edge (FIGS. 1, 2 and 8). Specifically, the collar portion 13d is formed in an angle shape in a plan view so as to project forward and anteriorly along the lower edge of the nasal dorsal locking portion 13a. Further, a pair of hooks 16 and 17 are projected obliquely forward from each of the upper both side edges of the frame 13 (FIGS. 2 to 5, 8 and 9). These hooks 16 and 17 are integrally formed with the cylindrical portions 16a and 17a having a diameter slightly smaller than the hole diameters of the through holes 12c and 12d and integrally with the cylindrical portions 16a and 17a, respectively. It is composed of the formed elliptical column portions 16b and 17b (FIGS. 4 and 5). The minor axis of the elliptical column portions 16b and 17b is the same as the diameter of the cylindrical portions 16a and 17a, and the major axis of the elliptical column portions 16b and 17b is formed larger than the diameter of the cylindrical portions 16a and 17a. The elliptical column portions 16b and 17b are formed with their center lines deviated outward from the center lines of the cylindrical portions 16a and 17a. Further, the frame 13 is preferably formed by injection molding or the like of a flexible plastic such as polypropylene or polyethylene, and in particular, the nose back locking portion 13a and the pair of leg portions 13b and 13c are the nose of the face 11. It is preferably formed to have a thickness of about 1 mm to 2 mm so as to easily adhere to the back 11b and the cheek 11d. Here, reference numerals 21a and 21b in FIG. 9 are a pair of first through holes formed at both upper ends of the frame 13, and reference numerals 22a and 22b are a pair of first through holes formed at both lower ends of the frame 13. It is the second through hole.

On the other hand, the pair of linear bodies 14 and 15 are preferably formed of a rubber cord or a cord (FIGS. 1 to 3). One end of one of the pair of linear bodies 14 and 15 is inserted into the first through hole 21a of the pair of first through holes 21a and 21b, and then a knot 14a for retaining is formed. The other end of one linear body 14 is inserted into one of the second through holes 22a and 22b of the pair of second through holes 22a, and then a knot 14b for retaining is formed (FIGS. 1 to 1). 3 and FIG. 9). Further, one end of the other linear body 15 of the pair of linear bodies 14 and 15 is inserted into the other first through hole 21b of the pair of first through holes 21a and 21b, and then the knot 15a for retaining is inserted. Is formed, and the other end of the other linear body 15 is inserted into the other second through hole 22b of the pair of second through holes 22a and 22b, and then a knot 15b for retaining is formed (FIG. 2). , FIG. 3, FIG. 5 and FIG. 9).

On the other hand, in order to attach the shield main body 12 to the frame 13, one of the pair of through holes 12c and 12d 12c is locked to one of the pair of hooks 16 and 17, and the other through hole 12d Is locked to the other hook 17 (FIGS. 4 and 5). As a result, when the shield body 12 is rotated downward around the pair of hooks 16 and 17, the eaves portion 12e rests on the collar portion 13d, and the shield body 12 covers the mouth 11a and the outer nostrils of the user 11. It is configured to be switchable between the covering position and the open position where the mouth 11a of the user 11 and the outer nostril are opened when the shield main body 12 is rotated upward about the pair of hooks 16 and 17. Since the hole diameters of the through holes 12c and 12d of the shield main body 12 are formed to be slightly smaller than the diameters of the cylindrical portions 16a and 17a of the hooks 16 and 17 of the frame 13, the shield main body 12 is formed into a pair of hooks 16 and 17. Sliding resistance is generated when rotating around the shield body 12, and when the shield body 12 is switched to the open position, the shield body 12 is temporarily fixed at this open position. Further, since the major axis of the elliptical column portions 16b and 17b is larger than the hole diameter of the through holes 12c and 12d, it is necessary to elastically deform the through holes 12c and 12d when the through holes 12c and 12d are fitted into the elliptical column portions 16b and 17b. is there.

In order to use the mask type shield 10 configured in this way, a pair of linear bodies 14 are formed in a state where a pair of through holes 12c and 12d of the shield main body 12 are formed in a pair of hooks 16 and 17 of the frame 13, respectively. , 15 can be used simply by hanging it on the ear 11b. Then, when the shield main body 12 is rotated downward about the pair of hooks 16 and 17, the eaves portion 12e of the shield main body 12 is placed on the flange portion 13d of the frame 13, and the shield main body 12 is the mouth 11a of the user 11. It is located at the covering position covering the outer nostril (FIGS. 1 (a) and 10 (a)). As a result, the mouth 11a and the outer nostril of the user 11 are covered with the shield main body 12, so that droplets containing the virus floating in the air due to the coughing or sneezing of the infected person are released from the user 11 of the mask type shield 10. It is possible to prevent the invasion of the mouth 11a and the nose. Even if droplets containing the virus try to invade between the shield body 12 and the frame 13 from above the shield body 12, the invasion is blocked by the eaves 12e and the collar 13d. Further, when the shield main body 12 is rotated upward around the pair of hooks 16 and 17, the shield main body 12 is located at an open position for opening the mouth 11a and the outer nostril of the user 11 (FIG. 1B). And FIG. 10 (b)), the user 11 can drink the drinking water of the PET bottle 18 without removing the mask type shield 10 (FIG. 10 (b)). At this time, the shield main body 12 is temporarily fixed in the open position by the sliding resistance between the through holes 12c and 12d of the shield main body 12 and the cylindrical portions 16a and 17a of the hooks 16 and 17 of the frame 13. Further, when the eating and drinking is finished, the shield main body 12 can be switched to the above-mentioned covering position by rotating the shield main body 12 downward about the pair of hooks 16 and 17. In this way, the shield body 12 can be quickly switched between the covering position and the open position.
