The present invention relates to a face guard.

A face guard that prevents droplet infection of viruses, fungi, and the like is disclosed (see, for example, Patent Document 1). The face guard includes a mounting band (band portion) that can fasten and fix the face guard to the head, and a transparent front shield portion (guard portion) that covers the entire face of the wearer.

Registered Utility Model No. 3228027

In the prior art, a face guard is manufactured by forming a band portion and a guard portion separately and assembling them together. When production efficiency is important, such as when mass-producing face guards, the process of assembling the band portion and the guard portion is troublesome, and it has been required to simplify the manufacturing process.
In addition, since the face guard is formed in three dimensions, when carrying the face guard removed or carrying a spare face guard, some ingenuity is required for carrying, and there is room for improvement from this point of view. It was.

Therefore, an object of the present invention is to provide a face guard that can simplify the manufacturing process and ensure the convenience of carrying.

In order to achieve the above object, the face guard of the present invention is formed flat in the unfolded form by a plate material having a light transmitting property and having a first surface and a second surface, and is assembled from the unfolded form into a three-dimensional form. In the three-dimensional form, the guard portion is arranged so as to face the face of the wearer and is connected to the upper end portion of the guard portion. A band portion arranged in the guard portion and a bent portion arranged between the guard portion and the band portion are provided, and in the bent portion, the first surface of the guard portion and the first surface of the band portion are provided. After being bent so as to overlap one surface, the first surface of the upper end portion of the guard portion and the second surface of the band portion face inward to form an annular shape, whereby the three-dimensional form is changed from the developed form to the three-dimensional form. It becomes.

According to this configuration, the face guard is formed flat by the plate material in the unfolded form. Therefore, for example, a face guard in which the guard portion and the band portion are integrated can be obtained by simply removing the sheet of the plate material with a mold. Can be manufactured. Therefore, the manufacturing process can be simplified as compared with the conventional face guard in which the guard portion and the band portion are separately formed and assembled.
The face guard is bent so that the first surface of the guard portion and the first surface of the band portion overlap at the bent portion, and then the first surface of the upper end portion of the guard portion and the second surface of the band portion are inside. It is possible to change from a developed form to a three-dimensional form by forming an annular shape facing. Therefore, it can be in a three-dimensional form when worn and in a deployed form when carried. Since the face guard is flat in the deployed form, it is not bulky and can be easily carried. Therefore, the face guard can ensure the convenience of carrying.

In the developed form, the bent portion may be formed in a straight line that is inclined outward from the upper side to the lower side in a plan view.

In the three-dimensional form, the bent portion is formed in a linear shape in the unfolded form, which is inclined outward from the upper side to the lower side in a plan view. Therefore, when the wearer wears it as a three-dimensional form, the bent portion inclines forward from above to below. As a result, the guard portion inclines forward from the band portion as it is mounted from above to below. Therefore, the face guard can be used comfortably because the guard portion does not come into contact with the wearer's face when worn.

In the developed form, the upper end portion of the guard portion may be formed with a recess that is separated from the band portion in a plan view and has a predetermined curvature.

According to this configuration, in the three-dimensional form, the concave portion of the guard portion can be arranged along the wearer's forehead. As a result, the face guard can be attached without discomfort as compared with the case where the concave portion is not formed at the upper end portion of the guard portion.

The second surface of the band portion may be smooth.

According to this configuration, the band portion can be slid with respect to the wearer's head in the worn state. As a result, the guard portion integrally formed with the band portion can be easily switched between a state in which the wearer's face is covered from the front and a state in which the lower end portion is arranged above the wearer's mouth. Therefore, for example, it is possible to switch so that the guard portion covers the mouth from the front during conversation and the guard portion does not cover the mouth from the front during meals, so that convenience can be improved. Therefore, the wearer can eat without removing the face guard, and can suppress the scattering of droplets from the wearer's mouth and the inhalation of viruses and bacteria.

The band portion may have an adjusting mechanism for adjusting the circumferential length of the head of the band portion in the three-dimensional form.

According to this configuration, the length of the head in the band portion in the circumferential direction can be adjusted in the three-dimensional form. As a result, the face guard can be attached to various wearers having different head sizes.

According to the present invention, it is possible to provide a face guard that can simplify the manufacturing process and ensure the convenience of carrying.

(How to assemble the face guard)
Hereinafter, an example of assembling the face guard 1 of the deployed form V1 into the three-dimensional form V2 will be described with reference to FIGS. 5 to 7.
FIG. 5 is a first explanatory view showing an example of assembling the face guard 1. FIG. 6 is a second explanatory view showing an example of assembling the face guard 1. FIG. 7 is a third explanatory view showing an example of assembling the face guard 1.
First, the wearer M (see FIG. 1) holds the first surface S1 of the face guard 1 in the deployed form V1 (see FIG. 3) with his / her hand H and faces the wearer M side.
Subsequently, as shown in FIG. 5, the wearer M bends the right end portion 30a and the left end portion 30b of the band portion 30 rearward at the bent portion 50, respectively. As a result, the first surface S1 of the right end portion 30a of the band portion 30 overlaps with the first surface S1 of the upper right end portion 10a of the guard portion 10. The first surface S1 of the left end portion 30b of the band portion 30 overlaps with the first surface S1 of the upper left end portion 10b of the guard portion 10. The wearer M holds the right end portion 30a and the upper right end portion 10a and the left end portion 30b and the upper left end portion 10b in an overlapping state.

Subsequently, as shown in FIG. 6, the wearer M applies a twisting force to the right end portion 30a and the left end portion 30b of the band portion 30 inward and forward in the left-right direction, respectively. As a result, the wearer M rotates the intermediate portion of the band portion main body 30c in the left-right direction from the front to the rear of the guard portion 10. The band portion 30 rotates once in the vertical direction from the deployed form V1, and the guard portion 10 is curved so as to project forward.
As a result, as shown in FIG. 7, the first surface S1 of the upper end portion 11 of the guard portion 10 and the second surface S2 of the band portion 30 form an annular shape facing the inside. The face guard 1 can be attached to the head M1 of the wearer M. In this way, the face guard 1 is assembled from the deployed form V1 to the three-dimensional form V2.

(How to adjust the face guard)
Hereinafter, the adjustment method of the face guard 1 assembled in the three-dimensional form V2 will be described with reference to FIGS. 1 and 4.
First, a method of adjusting the angle of the guard portion 10 with respect to the face of the wearer M will be described.
As shown in FIG. 1, the wearer M slides the band portion 30 in the vertical direction with respect to the head M1 while being mounted on the head M1. The guard portion 10 is inclined at a constant angle with respect to the band portion 30 when viewed from the left-right direction. Therefore, the wearer M can adjust the angle of the guard portion 10 with respect to the face of the wearer M by sliding the band portion 30 in the vertical direction. As a result, the guard portion 10 can be switched between, for example, a state in which the face of the wearer M is covered from the front (solid line portion) and a state in which the lower end portion 12 is arranged above the mouth of the wearer M (broken line portion). Therefore, the wearer M can eat without removing the face guard 1, and can suppress the scattering of droplets from the wearer M's mouth and the inhalation of viruses, bacteria, and the like.

Subsequently, a method of adjusting the length of the band portion 30 in the circumferential direction by the adjusting mechanism 40 will be described.
As shown in FIG. 4, in the three-dimensional form, the wearer M bends the intermediate portion of the band portion main body 30c in the left-right direction to form a flexible portion, and causes the flexible portion to project rearward. As a result, the length of the band portion 30 in the circumferential direction is apparently shortened. The wearer M inserts the locking piece 42 into the locking slit 41 in a state where the intermediate portion of the band portion main body 30c in the left-right direction is bent. When the locking piece 42 is inserted, the hook portion 46a passes through the end slit 44. The hook portion 46a that has passed through the end slit 44 engages with the first surface S1 of the band portion main body 30c. By locking the hook portion 46a and the first surface S1 of the band portion main body 30c, the band portion main body 30c is maintained in a bent state. In this way, the length of the band portion 30 in the circumferential direction is adjusted.

According to the above-described embodiment, the following actions and effects can be obtained.
In the present embodiment, since the face guard 1 is formed flat by the plate material P in the deployed form V1, for example, the guard portion 10 and the band portion 30 are integrated by simply pulling out the sheet of the plate material P with a mold. The face guard 1 can be manufactured. Therefore, the manufacturing process can be simplified as compared with the conventional face guard in which the guard portion 10 and the band portion 30 are separately formed and assembled.
The face guard 1 is bent at the bent portion 50 so that the first surface S1 of the guard portion 10 and the first surface S1 of the band portion 30 overlap with each other, and then becomes the first surface S1 of the upper end portion 11 of the guard portion 10. By forming the second surface S2 of the band portion 30 into an annular shape facing the inside, the developed form V1 can be changed to the three-dimensional form V2. Therefore, it can be in the three-dimensional form V2 when attached and in the expanded form V1 when carried. Since the face guard 1 is flat in the deployed form V1, it can be easily carried without being bulky. Therefore, the face guard 1 can ensure the convenience of carrying.

In the present embodiment, in the three-dimensional form, the bent portion 50 is formed in the unfolded form V1 in a linear shape that is inclined outward from the upper side to the lower side in a plan view. Therefore, when the wearer M wears the three-dimensional form V2, the bent portion 50 inclines forward as the wearer M wears it from above to below. As a result, the guard portion 10 is inclined forward from the band portion 30 from the upper side to the lower side when the guard portion 10 is attached. Therefore, the face guard 1 can be used comfortably because the guard portion 10 does not come into contact with the face of the wearer M when worn.

In the present embodiment, the upper end portion 11 of the guard portion 10 is formed with a recess 15 having a predetermined curvature, which is separated from the band portion 30 in a plan view in the deployed mode V1. According to this configuration, in the three-dimensional form, the recess 15 of the guard portion 10 can be arranged along the forehead of the wearer M. As a result, the face guard 1 can be attached without a sense of discomfort as compared with the case where the concave portion 15 is not formed in the upper end portion 11 of the guard portion 10.

In the present embodiment, the second surface S2 of the band portion 30 is smooth. According to this configuration, the band portion 30 can be slid with respect to the head M1 of the wearer M in the worn state. As a result, the guard portion 10 integrally formed with the band portion 30 can be easily switched between a state in which the wearer M's face is covered from the front and a state in which the lower end is arranged above the wearer M's mouth. .. Therefore, for example, it is possible to switch so that the guard portion 10 covers the mouth from the front during conversation and the guard portion 10 does not cover the mouth from the front during meals, so that convenience can be improved. Therefore, the wearer M can eat without removing the face guard 1, and can suppress the scattering of droplets from the wearer M's mouth and the inhalation of viruses, bacteria, and the like.

In the present embodiment, the band portion 30 has an adjusting mechanism 40 for adjusting the length of the band portion 30 in the circumferential direction in the three-dimensional form V2. According to this configuration, in the three-dimensional form V2, the length of the head M1 in the band portion 30 in the circumferential direction can be adjusted. As a result, the face guard 1 can be attached to various wearers M having different sizes of the head M1.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Configurations can be added, omitted, replaced, and other changes are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but only by the appended claims.
For example, in the above embodiment, the plate material P is PET, but the plate material P is not limited to this, and may be any material that has light transmission and is easily deformable.

In addition, it is possible to replace the constituent elements in the above-described embodiment with well-known constituent elements as appropriate without departing from the gist of the present invention, and each of the above-described modified examples may be appropriately combined.
