Hereinafter, embodiments of the face shield will be described with reference to the accompanying drawings.

First, the face shield 1A as a face shield will be described with reference to FIGS. 1 to 5.

First, the configuration of the face shield 1A will be described with reference to FIGS. 1 to 3. The face shield 1A includes a support 2, a fixing member 3, a shield body 4, and surface fasteners (in this example, two first surface fasteners 5A and 6A and two second surface fasteners 7A and 8A). ing.

The support 2 is made of a flexible plastic sheet material (for example, a polypropylene sheet material having a thickness of about 0.5 mm to 0.75 mm) and is at least on the left side of the head from the temporal region to the frontal region. In a band-like shape that can be attached to the attachment site extending to the right temporal region via the portion (for example, a long rectangular shape having a width of about 2.5 cm to 3.5 cm and a length of about 40 cm to 50 cm). It is formed. The left and right in this embodiment means the left and right for the wearer (user) of the face shield. The material of the support 2 is not limited to polypropylene, and may be various synthetic resins. Further, regarding the shape of the support 2, a simple shape (shape having a constant width) such as the rectangular shape of this example can be produced by punching or cutting from one plastic sheet material, and the cost can be increased. It is preferable because the reduction can be achieved most, but the reduction is not limited to this. For example, the portion of the support 2 located on the frontal region is wider than the portion located on each temporal region, or conversely, the portion located on the frontal region is located on each temporal region. It is also possible to make the shape narrower than the part. Even when this shape is adopted, it can be manufactured by punching or cutting from a single standard-sized plastic sheet material, so that it can be manufactured at low cost.

The fixing member 3 has a function of fixing the support 2 mounted on the mounting portion to the mounting portion. As an example in this example, the fixing member 3 is attached to the front surface (head) at one end of two ends in the length direction of the support 2 (in this example, the right end as an example). A third surface fastener 11 attached to the back surface when the surface that sometimes contacts the head is the back surface, and the other end of the above two ends of the support 2 (as an example in this example). , The left end) is composed of a fourth hook-and-loop fastener 12 attached to the front surface or the back surface (in this example, the back surface as an example).

Specifically, the third surface fastener 11 is formed in a rectangular shape having a short length (a square shape having one side equal to the width of the support 2) as an example, and is formed on the right end portion of the support 2. It is attached to the front by a method such as gluing so that it does not protrude from this end. The shape of the third surface fastener 11 is not limited to the above shape, and although not shown, it may have various shapes such as a circular shape and an elliptical shape.

On the other hand, the fourth surface fastener 12 is formed in a long rectangular shape (strip shape) having a width equivalent to the width of the support 2 as an example. Further, one end of the fourth surface fastener 12 is attached to the left end of the support 2 by a method such as adhesion. Further, in the state where the face shield 1A shown in FIG. 2 is attached to the head, the fourth surface fastener 12 has the other end passing through the back of the head and the right end of the support 2 (that is, that is). The length reaches the third surface fastener 11). With this configuration, the fixing member 3 has the third surface of the fourth surface fastener 12 reaching the right end portion (that is, the third surface fastener 11) of the support 2 when the face shield 1A is attached to the head. By sticking to the fastener 11, it forms an annular shape together with the support 2 (see FIGS. 1 and 2), and fixes the support 2 to the above-mentioned mounting site.

The fixing member 3 is not limited to the above configuration. For example, although not shown, the left end side of the support 2 is extended by the same length as the fourth hook-and-loop fastener 12, and another hook-and-loop fastener (on the third hook-and-loop fastener 11) is attached to the tip thereof. It can also be configured with a sticking hook-and-loop fastener). Further, a string is attached to the right end and the left end of the support 2 instead of the hook-and-loop fastener, and the strings are tied to each other to fix the support 2 to the mounting portion. Various configurations can be adopted, for example, can be adopted. However, in order to reduce the manufacturing cost while maintaining the ease of attachment / detachment, a configuration using a hook-and-loop fastener is preferable.

The shield body 4 is made of a flexible transparent plastic sheet material (for example, a sheet material made of polyethylene terephthalate (PET) having a thickness of about 0.2 mm to 0.75 mm) and has a size of covering the face. And is formed in shape. The material is not limited to polyethylene terephthalate, and other synthetic resins may be used as long as they are transparent and have chemical resistance.

Regarding the size of the shield body 4 in the vertical direction, in this example, in the mounted state shown in FIGS. 4 and 5, the upper end side is at least larger than the frontal region as shown in each figure. The size is defined so that it is located above and the lower end is at least below the chin. As for the size of the shield body 4 in the left-right direction, as shown in FIGS. 2, 4 and 5, the left end side reaches the left temporal region and the right end side reaches the right temporal region. It is stipulated. As a result, the shield body 4 can cover the entire face of the wearer wearing the face shield 1A.

Further, the shape of the shield body 4 is a rectangular shape as shown in FIG. 3 as an example in this example, but the shape may be appropriately rounded or chamfered. Further, although not shown, various shapes can be adopted, such as a trapezoidal shape in which the lower side is longer than the upper side, and conversely, a trapezoidal shape in which the upper side is longer than the lower side. Regardless of which of the above shapes is adopted, the shield body 4 can be manufactured by punching or cutting from a single standard-sized plastic sheet material in the same manner as the support 2, so that the shield body 4 can be manufactured at low cost. Is possible.

As an example, the first surface fasteners 5A and 6A are from the central CE1 in the length direction (horizontal direction) of the support 2, one first surface fastener 5A to the right, and the other. The first hook-and-loop fastener 6A is attached to the left side at a position separated by the same distance L1 by a method such as adhesion. Further, in the face shield 1A, as shown in FIG. 2, the center CE1 of the support 2 is mounted on the above-mentioned mounting portion in a state where the center CE1 of the support 2 substantially coincides with the center of the frontal region in the left-right direction. As shown in the figure, the above distance L1 is defined so that the first surface fastener 5A is located on the right temporal region and the first surface fastener 6A is located on the left temporal region. Further, as shown in FIG. 3, the first surface fasteners 5A and 6A of this example have substantially the same shape as the shape of the third surface fastener 11, that is, a rectangular shape having a short length (one side is a support 2). It may have a square shape equivalent to the width of).

As an example, the second surface fasteners 7A and 8A are the back surface of the shield body 4 (the surface facing the face when attached to the head. The surface not facing the face) as shown in FIGS. 1 to 3. Is the front surface of the shield body 4), and from the center CE2 in the left-right direction of the shield body 4, one second surface fastener 7A is to the right, and the other second surface fastener 8A is to the left. They are attached to positions separated by the same distance L2 (longer than the above distance L1) by a method such as bonding. In this example, as an example, as shown in FIGS. 1 to 3, the second surface fastener 7A is attached to the right edge of the shield body 4, and the second surface fastener 8A is attached to the left edge of the shield body 4. ing.

Further, the second surface fasteners 7A and 8A are attached to the same positions along the vertical direction of the shield body 4 (each position at the same height from the lower edge portion). Specifically, the second surface fasteners 7A and 8A are attached to each position slightly lowered by the same distance from the upper edge portion of the shield body 4.

Next, the assembly procedure and the usage method of the face shield 1A will be described with reference to FIGS. 1 to 5.

First, when assembling (attaching the shield body 4 to the support body 2), while bending the central CE2 of the shield body 4 by hand, the second surface fastener 7A of the shield body 4 is used as the first surface fastener 5A of the support body 2. The second surface fastener 8A of the shield body 4 is attached to the first surface fastener 6A of the support body 2, respectively. As a result, the assembly of the face shield 1A can be easily completed in a short time. In this face shield 1A, the distance between the second surface fasteners 7A and 8A (2 × L2) is longer than the distance between the first surface fasteners 5A and 6A (2 × L1). A gap SP (see FIG. 2) is formed between the portion between the first surface fasteners 5A and 6A on the front surface of the body 2 and the back surface of the shield body 4.

Next, when using this face shield 1A, hold the support 2 of the face shield 1A with one hand to position it at the above-mentioned mounting position on the head, and use the other hand to hold the fourth surface fastener 12 on the back of the head. Bend to the right temporal region via and attach it to the third surface fastener 11. As a result, the face shield 1A can be easily attached to the head in a short time. In this wearing state, as shown in FIGS. 2 and 4, the shield body 4 is located in front of the face (the entire face of the wearer is covered by the shield body 4).

In the face shield 1A, the above-mentioned gap SP remains generated even when the face shield is worn on the head as shown in FIG. 2, so that even the wearer wearing the spectacles does not interfere with the shield body 4. It is possible to use the face shield 1A. Further, it is possible to reduce the fogging of the shield body 4 due to the breath exhaled by the wearer.

The assembly procedure and usage of the face shield 1A are not limited to the above examples. For example, first, only the support 2 may be attached to the head, and then the shield body 4 may be attached to the support 2.

As described above, according to the face shield 1A, not only the shield body 4 but also the support body 2 can be easily manufactured by punching or cutting from the plastic sheet material, so that the manufacturing cost can be reduced. Further, according to this face shield 1A, the shield body 4 is attached to the support 2 with hook-and-loop fasteners (in this example, the first-face fasteners 5A and 6A and the second-face fasteners 7A and 8A), so that the shield body 4 can be easily assembled. At the same time, the position of the shield body 4 with respect to the support 2, that is, the position of the shield body 4 with respect to the face can be easily changed. For example, the angle of the shield body 4 with respect to the support 2 and the fixing member 3 which form an annular shape as a whole when mounted on the head is set to, for example, an angle θ1 which is substantially a right angle as shown in FIG. It can be set to an acute angle θ2 as shown in 5, or it can be set to an obtuse angle (not shown), thereby changing the position (angle) of the shield body 4 with respect to the face. be able to. In addition, the face shield 1A can be easily attached and detached.

Further, in this face shield 1A, two first surface fasteners 5A and 6A are attached to each portion located on the left temporal region and the right temporal region of the support 2 attached to the attachment portion, and the shield body. Two second hook-and-loop fasteners 7A and 8A are attached to the left edge portion and the right edge portion of No. 4 at the same positions along the vertical direction, and the shield body 4 is attached to the right edge portion of the first surface fastener. 5A is attached to the second surface fastener 7A of the support 2, and the first surface fastener 6A attached to the left edge portion is attached to the second surface fastener 8A of the support 2 and attached to the support 2. Therefore, according to the face shield 1A, the shield body 4 can be attached to the support 2 in the shape of a gutter that curves along the face, so that the droplets from the front side of the face are prevented from adhering to the face. Not only that, but also the droplets from the side of the face can be prevented from adhering to the face. Further, although not shown, instead of the above configuration, for example, one hook-and-loop fastener is attached over the entire area between the left temporal region and the right temporal region of the support 2. It is also possible to adopt a configuration in which one surface fastener is attached to the entire area between the left edge portion and the right edge portion of the shield body 4 and the shield body 4 is attached to the entire support body 2.

Further, when the configuration in which the shield body 4 is fixed to the support 2 at two places as in this example is adopted, as described above, it is second than the distance (2 × L1) between the first surface fasteners 5A and 6A. By increasing the distance (2 × L2) between the hook-and-loop fasteners 7A and 8A, the gap SP between the portion between the hook-and-loop fasteners 5A and 6A on the front surface of the support 2 and the back surface of the shield body 4 (FIG. 2) can occur. Therefore, according to the face shield 1A having this configuration, even a wearer wearing eyeglasses can use the face shield 1A in a state where the eyeglasses do not interfere with the shield body 4.

As for the hook-and-loop fasteners attached to the shield body 4, the lengths in the vertical direction of the surface fasteners 7B and 8B of the face shield 1B shown in FIG. 6 are set to the lengths of the first surface fasteners 5A and 6A of the support body 2. It is also possible to adopt a configuration in which the length is longer than the length in the vertical direction (width of the support 2). Hereinafter, the face shield 1B will be described. In the face shield 1B and the face shield 1A, the vertical lengths of the second surface fasteners 7B and 8B are the vertical lengths of the second surface fasteners 7A and 8A (the same length as the width of the support 2). Since the configurations are the same except that they are longer than the above, the same configurations as those of the face shield 1A are designated by the same reference numerals, and duplicate description will be omitted.

In this face shield 1B, the vertical lengths of the second surface fasteners 7B and 8B on the shield body 4 side are longer than the vertical lengths of the first surface fasteners 5A and 6A on the support body 2 side. In the assembled state (mounted on the head) shown in (1), the mounting position of the shield body 4 on the support 2 is changed (adjusted) in the vertical direction within the range of the vertical lengths of the second hook-and-loop fasteners 7B and 8B. ) Is possible. Therefore, according to the face shield 1B, in addition to the effect of the face shield 1A described above, the position of the shield body 4 with respect to the face when worn on the head can be changed (adjusted) in the vertical direction.

As for the hook-and-loop fasteners to be attached to the support body 2, the lengths in the left-right direction of the first hook-and-loop fasteners 5B and 6B of the face shield 1C shown in FIG. 8 are set to the second surface fasteners 7A and 8A of the shield body 4. It is also possible to adopt a configuration in which the length is longer than the length in the left-right direction of. Hereinafter, the face shield 1C will be described. The face shield 1C and the face shield 1A are configured except that the lengths of the first surface fasteners 5B and 6B in the left-right direction are longer than the lengths of the second surface fasteners 7A and 8A in the left-right direction. Since they are the same, the same reference numerals are given to the same configurations as the face shield 1A, and duplicate description will be omitted.

In this face shield 1C, as shown in FIG. 8, the rightmost first surface fastener 5B of the first surface fasteners 5B and 6B on the support 2 side is shielded at a position along the left-right direction of the right end thereof. The position of the right end of the second surface fastener 7A, 8A on the right side of the body 4 is almost the same as the position of the right end of the second surface fastener 7A, and the position of the left end along the left-right direction is more centered than the left end of the second surface fastener 7A. By being located closer to CE1, the length of the second hook-and-loop fastener 7A in the left-right direction is longer (for example, twice or more). Further, with respect to the leftmost first surface fastener 6B on the support 2 side, the position of the left end along the left-right direction substantially coincides with the position of the left end of the left end surface fastener 8A of the shield body 4, and the right end thereof. Since the position along the left-right direction of the second surface fastener 8A is located closer to the center CE1 than the right end of the second surface fastener 8A, it becomes longer (for example, twice or more) than the length in the left-right direction of the second surface fastener 8A. There is.

Due to this configuration, in this face shield 1C, the central CE2 of the shield body 4 is curved, and the left end of the second surface fastener 7A of the shield body 4 is substantially aligned with the left end of the first surface fastener 5B of the support body 2. The first surface of the shield body 4 is attached to the first surface fastener 5B in a matched state, and the right end of the second surface fastener 8A of the shield body 4 is substantially aligned with the right end of the first surface fastener 6B of the support body 2. It is possible to assemble the face shield 1C by attaching it to the fastener 6B. In the face shield 1C assembled in this way, as shown in FIG. 9, there is a large gap SP between the portion between the first surface fasteners 5B and 6B on the front surface of the support 2 and the back surface of the shield body 4. Is generated. As a result, in this face shield 1C, even a wearer wearing eyeglasses can use the face shield 1C in a state where the eyeglasses do not interfere with the shield body 4.

On the other hand, in this face shield 1C, the shield body 4 is not curved, and the right end of the second surface fastener 7A of the shield body 4 is substantially aligned with the right end of the first surface fastener 5B of the support body 2. Attach it to the first surface fastener 5B, and for the second surface fastener 8A of the shield body 4, attach it to the first surface fastener 6B with its left end almost aligned with the left end of the first surface fastener 6B of the support 2. , It is possible to assemble the face shield 1C. In the face shield 1C assembled in this way, as shown in FIG. 10, there is a gap SP between the portion between the first surface fasteners 5B and 6B on the front surface of the support body 2 and the back surface of the shield body 4. It will be in a state where it hardly occurs. As a result, in this face shield 1C, the wearer who does not wear glasses can use the face shield 1C with the shield body 4 arranged near the face. That is, according to this face shield 1C, the width (size) of the above-mentioned gap SP is adjusted by changing the mounting position of the second surface fasteners 7A and 8A to the first surface fasteners 5B and 6B. Can be done.

Further, as in the face shield 1D shown in FIG. 11, the above-mentioned characteristic configuration of the face shield 1B (the configuration including the second surface fasteners 7B and 8B) and the above-mentioned characteristic configuration of the face shield 1C (the first). Of course, a configuration having both one-sided fasteners 5B and 6B) may be adopted. The face shield 1D is composed of only the components included in any of the face shields 1B and 1C. Therefore, the same reference numerals are given to the same configurations, and duplicate description will be omitted.
