It was a dust-proof measure that was not particularly welcomed by women, such as goggle marks on the face due to pressure when worn.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a dustproof hood for a cleaning operation, which can prevent eyelashes and other exfoliated substances from the human body from falling from the opening on the face side of the dustproof hood. It is.

[0005]

Therefore, the present invention covers the opening of the hood body surrounding the head at the eye position with a transparent film, and covers the position from the nose to the mouth with a breathable material attached to the hood body. Constructs a dust-proof hood. The transparent film is detachable from the hood body, and the lower portion of the transparent film is connected to a breathable material covering a position from the nose to the mouth. The breathable material is composed of an outer cloth and an inner cloth, and a lower portion of the transparent film is connected as a structure sandwiched between the outer cloth and the inner cloth.

[0006] The hood body has a collar at the upper part of the opening, and the upper part of the transparent film is connected to the collar by a detachable fixing tool. Furthermore, the breathable material is detachably attached to the hood body by a detachable tool, and the lower portion of the transparent film is detachably attached to the breathable material by a fixture.

[0007]

1 and 2 show a dustproof hood 1 according to the present invention. The dustproof hood 1 is constituted by a hood main body 2 surrounding the head. The hood body 2
In order to wrap the head of the worker, the cloth is, for example, a cloth having a high weaving density with a soft conductive thread, and the opening 3 is formed at least at a position corresponding to the eyes at the face of the worker. Below the opening 3 of the hood body 2, a position from the nose to the mouth is cut out, and the cut out portion is closed by a breathable material 5.

The air permeable material 5 is made of, for example, a nonwoven fabric or a mesh-like fiber having a size that prevents passage of dust.
The air permeability allows the worker to breathe easily. In this embodiment, the hood body 2
The inner cloth 7 sewn up, down, left and right with respect to the cutout portion, and the sewing is sewn only at the lower and left and right portions with respect to the hood body 2 and sewn to the inner cloth 7 at the intermediate position in the left and right direction And the outer cloth 6. As a result, the outer cloth 6 and the inner cloth 7 form an upper opening type pocket above an intermediate height.

The opening 3 is covered with a transparent film 4. That is, the transparent film 4 is attached to the collar 10 formed above the opening 3 by the fixture 8 such as a snap button, and the left and right fixtures 9.
Are detachably attached to the lower edge of the opening 3. As a result, the lower portion of the transparent film 4 is detachably connected to the hood body 2 as a structure sandwiched between the outer cloth 6 and the inner cloth 7 as the breathable material 5. The transparent film 4 may be formed in a conical shape with its upper part bent, or may be integrally formed into an appropriate shape, for example, a hemisphere. The internal space of the transparent film 4 is a space for accommodating spectacles, and also secures an appropriate amount of air for preventing fogging.

In this embodiment, the hood body 2
Is constructed by combining a plurality of draping cloths at a portion covering a face, and combining a cloth covering a back side of a head and a cloth covering an upper surface of a head. In order to adjust the circumference of the head, a belt 13 and an adjusting tool 11 for adjusting the length of the belt are provided at the rear part. A skirt portion 12 is sewn to a lower portion of the hood main body 2 to cover a portion from a neck to a shoulder of an operator.

According to the dustproof hood 1 having the above structure, since the opening 3 at the position of the eyes is covered with the transparent film 4, the eyelashes and other debris from the human body can be removed from the human body while securing the field of view of the worker. Without scattering from inside to outside
As a result, foreign substances can be prevented from being mixed into the product. When the user's eyelashes fall from the human body in the wearing state of the dustproof hood 1, the worker's eyelashes are guided by the inner surface of the transparent film 4 and stored in the pocket-like portion of the inner cloth 7 and the outer cloth 6.
Eventually, it will be held in this part and will not scatter outside. In addition, the breathable material 5 (outer cloth 6 and inner cloth 7) such as mesh fiber or non-woven fabric is sewn on the lower part of the transparent film 4, that is, the portion corresponding to the nose and mouth of the worker. Due to its breathability, work can be performed in a comfortable breathing state.

Since the transparent film 4 is fixed at the upper portion and pressed down at the lower portion as being sandwiched between the outer cloth 6 and the inner cloth 7, the wearer does not feel a sense of tightening. I have. Moreover, when the operator moves his / her head, the lower part of the transparent film 4 slides up and down to some extent with respect to the breathable material 5 (the outer cloth 6 and the inner cloth 7), thereby allowing the movement of the transparent film 4. Therefore, the rigidity of the transparent film 4 does not hinder the movement.

Since the transparent film 4 can be easily attached to and detached from the hood main body 2, when the hood main body 2 is sterilized, the transparent film 4 which is vulnerable to heat can be removed. Further, when the transparent film 4 is damaged, only the transparent film 4 is replaced, so that the hood body 2 can be continuously used, which is economical for the user. In particular, if the breathable material 5 is made of a mesh material, the breathing is efficiently discharged and inhaled, so that the inside of the dustproof hood 1 can be prevented from becoming uneven and the transparent film 4 is less clouded.

When the collar 10 is formed on the upper part of the opening 3, light from the upper part does not enter the inside of the transparent film 4 and irregular reflection on the inner surface of the transparent film 4 can be prevented. The visibility improves.

Next, in the example of FIG. 3, the hood main body 2 is separated from the hood main body 2 by separating the air permeable material 5 with the left and right attachments 14 such as Velcro tape.
It is an example of attaching to. In this case, the transparent film 4
At the lower part, it is attached to the inner cloth 7 of the breathable material 5 by the fixture 9. The hood body 2 is attached to, for example, a collar 9 of the hood body 2 by a fixture 8 at an upper portion as necessary. Here, the lower edge of the breathable material 5 is integrated with a cloth 15 for covering the neck portion. In addition, rubber cords 16 are attached to the left and right ends of the cloth 15.
In addition, a cord 17 for applying the cloth 15 under the chin is passed through a through hole on the lower side thereof.

The dust-proof hood 1 can be used inside a so-called clean room in the manufacturing process of precision instruments and semiconductor products, in addition to operations for manufacturing chemicals and the like.

[0017]

According to the present invention, since the opening at the position of the eye of the hood body is covered with the transparent film, scattering of eyelashes and the like from the opening can be prevented, and foreign matter is prevented from entering the product. The breathable material covers the area from the worker's nose to the mouth, and breathability can be ensured at that position, making it easy for the worker to breathe, and the inside of the transparent film becomes cloudy or uneven. It is possible to work in a comfortable state without any trouble.

The transparent film is detachably attached to the hood body, is connected between the outer cloth and the inner cloth as a breathable material, and is detachably attached only to the front part of the hood body. Therefore, the work can be performed in a comfortable state without giving a feeling of tightening to the wearer. Also, since the lower portion of the transparent film is sandwiched between the pocket-like portions between the inner cloth and the outer cloth as the breathable material, it is advantageous because eyelashes of the human body do not accumulate in the pocket-like parts and scatter. . In addition, a collar is provided on the hood body, which covers the upper part of the transparent film and is detachable from the upper part of the transparent film by a fixing device. Since light does not enter the inside of the transparent film, there is no glare due to irregular reflection, and visibility is good.
