Description

The present disclosure relates to work hoods.

In operations that require cleanliness such as semiconductor manufacturing, pharmaceutical manufacturing, and food manufacturing, work hoods that completely cover the head are used to prevent foreign matter such as hair from entering the product. (See Patent Document 1, for example). In the work hood of Patent Document 1, two pieces of cloth hanging from both sides of the face are fixed using fasteners such as hook-and-loop fasteners and snap buttons integrated with the tape cloth, thereby making the work hood. It has a configuration that exposes the face while fitting it to the face.

When fixing two pieces of cloth hanging down from both sides of the face, it is necessary to overlap fasteners provided on the two pieces of cloth (for example, see Non-Patent Document 1). At this time, two pieces of cloth hanging down from both sides of the face were held in each hand, fasteners were overlapped, and the fasteners were pressed from the outside of the hood to fasten.

When wearing a work hood, fix two pieces of cloth hanging from both sides of the face near the chin and neck to prevent hair from coming out around the face. Since the area around the chin and neck cannot be seen directly, the fasteners are placed on top of each other by groping around, relying on the sensations of the fingertips of both hands. For this reason, it sometimes took time to put on the working hood.

Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Note that the present disclosure is not limited to the embodiments shown below. These implementation examples are merely illustrative, and the present disclosure can be implemented in various modified and improved forms based on the knowledge of those skilled in the art. In addition, in this specification and the drawings, constituent elements having the same reference numerals are the same as each other.

1 and 2 show a first example and a second example of the configuration of the working hood according to the embodiment. The work hood 1 according to the embodiment includes a ring belt cloth 12 , a crown pressing cloth 14 , a hood cloth portion 15 , an upper belt 131 , a first hanging belt 132 and a second hanging belt 133 . The upper band 131 covers the wearer's forehead and stretches in direction 32a. A first hanging band 132 is connected to the upper band 131 and extends from the wearer's forehead toward the chin. A second hanging band 133 is connected to the upper band 131 and extends from the wearer's forehead toward the chin.

The angle θ formed by the upper band 131 and the first hanging band 132 at the junction of the upper band 131 and the first hanging band 132 is approximately 90°, preferably about 70 to 90°. . The same applies to the angle formed by the upper band 131 and the second hanging band 133 at the junction of the upper band 131 and the second hanging band 133 . By arranging the upper band 131, the first hanging band 132, and the second hanging band 133 in this way, the wearer's wide field of vision is ensured, and the first hanging band 132 and the second hanging band 132 are arranged. The hanging band 133 can be fitted to the wearer's face.

In the first example shown in FIG. 1 , fasteners 41 and 42 are arranged on the first hanging band 132 and fasteners 43 and 44 are arranged on the second hanging band 133 . In the second example shown in FIG. 2 , the fastener 41 is arranged on the first hanging band 132 and the fastener 44 is arranged on the second hanging band 133 . The fastener 42 is arranged at the distal end of the first hanging band 132 . The fastener 44 is arranged at the tip of the second hanging band 133 .

FIG. 3 shows an example of the state before wearing the first example of the working hood. The fasteners 41 and 42 are arranged on the side of the first hanging band 132 facing the facial side (hereinafter referred to as the outer side), and the fasteners 43 and 44 are arranged on the facial side of the first hanging band 132 (hereinafter called the outer side). , called the inside). The spacing between the fasteners 41 and 42 and the spacing between the fasteners 43 and 44 are substantially equal.

The fasteners 42 and 43 are optional parts that detachably lock the fasteners 42 and 43, and include hook-and-loop fasteners and buttons. For example, it is preferably a snap button embedded on a cloth tape. In this case, it is preferable that the colors of the cloth tape and the snap button are different. Furthermore, it is preferable that the color of the first hanging band 132 and the second hanging band 133 and the color of the cloth tape are different. For example, when the color of the first hanging band 132 and the second hanging band 133 is white, the color of the cloth tape is blue and the color of the snap button is blue. The colors are not limited to white and blue, and can be any color. The same is true for fasteners 44 and 41 .

FIG. 4 shows an example of a wearing state of the first example of the working hood. The fastener 42 and the fastener 43 are locked, and the fastener 44 and the fastener 41 are locked. Fasteners 41 and 42 are positioned on the outside of first hanging strap 132 and fasteners 43 and 44 are positioned on the inside of first hanging strap 132 so that the first hanging strap 132 and the Two hanging belts 133 are overlapped without being twisted to form the opening 11 .

In the first example of the configuration of the working hood, as shown in FIG. 4, the first hanging band 132 and the second hanging band 133 overlap each other. In this state, the same degree of tension is applied to the connecting portion of the first hanging band 132 with the upper band 131 and the connecting portion of the second hanging band 133 with the upper band 131 . For this reason, in the work hood 1 according to the present disclosure, the first hanging band 132 and the second hanging band 133 are firmly attached to the face, the effect of preventing hair from falling is significantly increased, and the user can wear the work hood 1 without discomfort. can continue.

If the fasteners 41 and 43 are positioned near the mandible, there is the potential for fastener "stitching". Therefore, in the present disclosure, fasteners are arranged on the left and right sides of the face. Specifically, the fasteners 41 are arranged in the longitudinal direction of the first hanging band 132 so as to be positioned between the wearer's eyes and mouth. Moreover, the fastener 43 is arranged so as to be positioned between the wearer's eyes and mouth in the longitudinal direction of the second hanging band 133 . By arranging the fasteners on the left and right sides of the face in this way, the first hanging band 132 and the second hanging band 133 can be fitted around the face without gaps with little individual difference. . As a result, the effect of preventing hair from falling is extremely high. In addition, since there is almost no unevenness in the fabric after wearing, there is little burden on the wearer even when worn for a long time. In addition, since the fasteners are placed on the left and right sides of the face, it is easy to fasten in terms of height.

Further, in the work hood 1 according to this embodiment, it is preferable that the upper band 131 , the first hanging band 132 and the second hanging band 133 expand and contract in the circumferential direction 32 of the opening 11 . Thereby, the working hood 1 can be fitted around the face.

Here, it is preferable that the fastener 43 is arranged closer to the hood cloth portion 15 than the fastener 42 is. As a result, as shown in FIG. 5, the tip of the first hanging band 132 is arranged inside the outer edge 133E of the second hanging band 133, thereby suppressing movement of the overlapping portion under the chin. and the first hanging band 132 can be fitted to the wearer's chin. The difference _Δ42 between the tip of the first hanging band 132 and the outer edge 133E is arbitrary, and even a small _Δ42 will have this effect.

Moreover, it is preferable that the fastener 41 is arranged closer to the hood cloth portion 15 than the fastener 44 is. As a result, as shown in FIG. 5, the distal end of the second hanging band 133 is positioned inside the outer edge 132E of the first hanging band 132, thereby preventing the overlapping portion under the chin from moving. It can be constrained to allow the third hanging band 133 to fit the wearer's chin. The difference .DELTA.44 between the tip of the second hanging band 133 and the outer edge _132E is arbitrary, and even a small _.DELTA.44 will have this effect.

Explain how to put on the work hood. The wearer pinches the fastener 42 at the tip of the first hanging band 132 hanging down on the right side of the face with the thumb and index finger or middle finger of the right hand, and puts the tip of the second hanging band 133 on the left cheek of the face. It is moved to the position of the fastener 43 arranged around, and the fastener 42 and the fastener 43 are overlapped with the thumb and the index finger or the middle finger of the right hand to lock the fastener 42 and the fastener 43.例文帳に追加

Next, the wearer grasps the fastener 44 at the tip of the second hanging band 133 with the thumb and index finger or middle finger of the right hand, and places the tip of the first hanging band 132 around the right cheek of the face. The fastener 41 is moved to the position of the fastener 41, and the fastener 44 and the fastener 41 are overlapped with the thumb and index finger or middle finger of the right hand to lock the fastener 44 and the fastener 41.例文帳に追加At this time, since the fastener 42 and the fastener 43 are already locked, the operation for overlapping the fastener 44 and the fastener 41 is very easy.

In this manner, the working hoods of the first example and the second example can be easily clamped between the thumb and the index finger or the middle finger even with one hand. By fastening on both the left and right sides, it is possible to obtain an effect equivalent to that of a cover-type innerwear even with a simple wearing method. In addition, since there is no need for a complicated wearing method such as that of the covering type, repeated attachment and detachment can be easily performed.

Here, as shown in FIG. 3 , the first hanging band 132 and the second hanging band 133 are longer than the hood cloth portion 15 and protrude from the hood cloth portion 15 . Fasteners 42 and 44 are preferably located at the distal ends of hanging strips 133 of the . This makes it easier to wear the working hood.

Although the first example and the second example of the configuration of the work hood show examples using the right hand, the present disclosure is not limited to this. For example, as shown in FIGS. 6 and 7, fasteners 41 and 42 are positioned inside first hanging strap 132 and fasteners 43 and 44 are positioned outside second hanging strap 133. may As a result, the fastener 44 and the fastener 41 can be overlapped, and the fastener 42 and the fastener 43 can be overlapped with only the left hand.

The annular belt cloth 12 is arranged so as to cover the entire upper head portion and is stretchable in the circumferential direction 31 of the upper portion of the head. The upper head includes the frontal, temporal, and occipital regions. The annular belt cloth 12 is stretchable in the circumferential direction 31 of the upper head. For example, as shown in FIG. 8, the lateral direction _DH of the knit structure is arranged in the circumferential direction 31 of the upper head. Thereby, the working hood 1 can be fitted to the wearer's head. When the working hood 1 is worn, it maintains an appropriate feeling of fit and does not give discomfort even when used for a long period of time. The width of the annular belt cloth 12 may be appropriately determined depending on the size of the work hood 1, and may be approximately 2 to 8 cm. The circular belt cloth 12 is preferably joined at the back of the head.

The crown presser fabric 14 covers the crown of the wearer's head and is stretchable with respect to the coronal or temporal direction 33 . The expansion and contraction direction of the crown presser cloth 14 is limited to the temporal direction 33 and is not expanded and contracted in the frontal and occipital directions, so that the circular belt cloth 12 can be held above the head. As the top of the head presser cloth 14 expands and contracts in the direction 33 of the temporal region, the fit to the top of the wearer's head increases.

The hood cloth portion 15 is arranged adjacent to the annular belt cloth 12 , the first hanging band 132 and the second hanging band 133 , and is made of a knit material that stretches in the circumferential direction 34 . For example, the lateral direction _DH of the knit structure is arranged in the circumferential direction 34 . It is preferable that a rubber that stretches in the circumferential direction 34 is arranged at the position of the back of the hood cloth portion 15 . This makes it possible to enhance the fit to the wearer's head.

The knitted material is, for example, a cloth having a weft-knitted knit structure with the horizontal direction _DH of the ground grain as the longitudinal direction, as shown in FIG. Such a knit structure has good stretchability in the transverse direction _DH . The weft knitting structure is not particularly limited, and for example, in addition to the plain knitting shown in FIG. 8, conventionally known structures such as rib knitting, rubber knitting, and pearl knitting can be employed.

The fibers forming the knit material preferably contain hydrophilic fibers so as to absorb moisture such as perspiration. Hydrophilic fibers are, for example, cotton, rayon, highly hydrophilic synthetic fibers. A highly hydrophilic synthetic fiber is, for example, Sophista (registered trademark), which is a polyester material containing hydrophilic groups. Sophista (registered trademark) is highly hydrophilic and does not swell, so it can absorb sweat and moisture and quickly dissipate it. In addition, the fibers constituting the knit material preferably contain fibers with high thermal conductivity such as EVAL so that heat on the surface of the skin can be diffused.

In addition, it is preferable that a plurality of knit materials are layered so that the elasticity of the knit material is maintained. In this case, it is preferable that the layers are superimposed so that the surface containing a large amount of hydrophilic fibers becomes the front surface so that sweat on the face can be efficiently absorbed.

The work hood 1 according to the embodiment may include a flange portion 22 . The collar portion 22 is arranged between the annular belt cloth 12 and the upper belt 131 and has an arc shape, and is shorter than the upper belt 131 . The provision of the brim portion 22 also has the effect of protecting the wearer's eyes from strong light and dust. Also, by bringing the curvature of the brim portion 22 close to the curvature of the wearer's forehead, the brim portion 22 is stabilized on the forehead, and the hood is prevented from moving.

It is preferable that the working hood 1 according to the embodiment include auxiliary cloth portions 121 and 122 . FIG. 9 shows a state in which the work hood 1 is worn by the wearer. The auxiliary cloth portion 121 is arranged at the junction of the upper belt 131 and the first hanging belt 132 . The auxiliary cloth portion 122 is arranged at the junction of the upper belt 131 and the second hanging belt 133 .

The auxiliary cloth portion 121 is sewn together at the boundary between the upper belt 131 and the annular belt cloth 12 , and sewn together at the boundary between the first hanging belt 132 and the hood cloth portion 15 . As a result, the angle between the upper band 131 and the first hanging band 132 can be maintained, and the first hanging band 132 can be prevented from slipping toward the wearer's throat. Similarly to the auxiliary cloth portion 121 , the auxiliary cloth portion 122 is sewn together at the boundary between the upper belt 131 and the annular belt cloth 12 , and sewn together at the boundary between the second hanging belt 133 and the hood cloth portion 15 .

Further, the auxiliary cloth portion 121 may be sewn to the upper band 131 at the connecting portion 21c, and sewn to the first hanging band 132 at the connecting portion 21d. . Thereby, the fitting feeling of the auxiliary cloth part 121 can be improved. The same applies to the auxiliary cloth portion 122 as well.

The auxiliary cloth portion 121 has an insertion portion 21e between the coupling portion 21c and the coupling portion 21d, through which the temple of the spectacles 4 can be inserted. By inserting the temple of the spectacles 4 through the insertion portion 21e, the wearer can wear the spectacles even if the auxiliary cloth portion 121 is present. The same applies to the auxiliary cloth portion 122 as well.

The work hood of the present disclosure can be applied, for example, as a work hood during manufacturing operations for semiconductors, foods, pharmaceuticals, and the like.
