Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hood type dustproof hood that is used together with work clothes for manufacturing semiconductor parts in a clean space in a clean room.

[0002]

[Prior art]

 In this type of dustproof hood, those shown in FIGS. 1 and 2 are already known in order to adjust the size around the head when worn. In the case of the one shown in Fig. 1, one end of a horizontal strap is fixed at a position above the occipital region of the hood body, and the free end of the strap is fastened with Velcro tape or the like to adjust the size around the head. ing. Also, in the case of FIG. 2, the size of the head and the size of the circumference from the lower side of the ear to the chin are attempted by providing another set of adjusting means at the lower position of the back of the head.

[0003]

[Problems of conventional technology]

 However, with the above structure, it is possible to adjust the size around the head in the upper part of the ear, but the length of the circumference from the lower side of the ear to the chin is not sufficiently adjusted, and the hood body does not come into close contact with the face. Is insufficient, the air inside the dustproof hood is likely to come out to the outside especially on the face, especially in the exposed area, and exhalation during breathing flows into the ears and the neck muscles, causing discomfort, which is a work obstacle. Has become.

[0004]

[The purpose of the device]

 Therefore, the object of the present invention is to fit the front surface of the hood body to the wearer's face and head closely by matching the three-dimensional shape of the face, especially the head from the cheek to the chin, without tightening the forehead. That is.

[0005]

[Solution of the device]

 In view of the above object, the present invention provides a hood main body of a salient type in which the upper and lower rear ears of the hood main body and the lower rear and rear ears of the hood are connected by a strap having an adjustable length. By doing so, the dustproof hood can be brought into close contact with the head, especially the face, and the drawbacks of the prior art are solved. That is, by adjusting the tightening condition of the adjustable straps, the forehead part of the main body of the hood is brought into close contact with the face, and at the same time, the tightening margin in the stroking direction allows the chin from the lower side of the ear. Since the length of the circumference of the line to the can be adjusted, the mask part of the hood body fits properly around the nose and mouth of the wearer, and dust from the face side opening of the dustproof hood is suppressed. The exhaled air then flows to the ears and neck, eliminating the discomfort of the wearer.

[0006]

Embodiment 1 The embodiments of FIGS. 3 and 4 are typical examples of the present invention. In these figures, the dustproof hood 1 is constituted by a hood main body 2 of a salient type. The hood main body 2 is formed by sewing a occipital region cloth 3, a forehead cloth 4, and a face cloth 5 into a tubular shape. The top cloth 6 is applied to the upper opening and the shoulder cloth 7 is sewn to the hem side opening. The structure is attached. In addition, a mesh cloth ear cloth 8 is sewn on the occipital region cloth 3 at a position corresponding to the ear, and a hemispherical surface is formed on the face cloth 5 corresponding to the wearer's nose and mouth. A quilted mask portion 9 is formed by stacking a plurality of breathable cloths each having a breathable shape, and a salient opening 10 is formed between the mask portion 9 and the forehead cloth 4. There is. In order to prevent dust generation, these fabrics are woven with poorly breathable material and conductive yarns for antistatic weaving. The face cloth 5 is a stretchable cloth.

A characteristic part of this embodiment is a mounting structure of the strap 11 having the adjustable length and the two loop cords 12. That is, the left and right loop cords 12 are attached to the upper and lower rear positions of the ears of the hood body 2 at the upper and lower ends thereof, while the strap 11 is passed through the loop cords 12. The slide ring 13 and the adjuster 14 that also serves as the slide ring are passed through in a loop shape and are attached so that the loop length can be adjusted.

When wearing, the worker adjusts the height of the strap 11 with respect to both loop straps 12 by sliding the slide ring 13 and the adjuster 14 that also serves as a slide ring, and adjusts the tightening degree of the strap 11 by the adjuster 14. By adjusting, the strap 11 and the loop string 12 are fastened in a state where the hood body 2 is connected to the back of the head in a crossing manner. As a result, the front side portion of the hood body 2 is in close contact with the wearer's face, and the tightening force in the crossing direction at the back of the head causes the mask portion 9 and the eye-opening opening on the face from the cheek to the chin. The part 10 comes into close contact with the face.

Therefore, dust generation from the face is suppressed, and exhaled air does not flow to the ears or the neck of the hood body 2 and the wearer does not feel uncomfortable. The tightening degree of the strap 11 is evenly distributed to the left and right loop straps 12. Further, the degree of tightening on the forehead side and the degree of tightening from the chin to the cheek can be adjusted by adjusting the height of the strap 11 with respect to the loop strap 12.

[0010]

Second Embodiment A dustproof hood 1 shown in FIG. 5 is a hood main body 2 of the same type as that described above, in which two straps 11 are used, and one end of each strap 11 is sewn at the upper rear position of both ears. In this example, the sewing is performed in a state of being crossed with a rope, and the free end on the lower end side is attached by a stopper 15 such as a velcro tape so that the substantial length adjustment of the strap 11 with respect to the hood body 2 can be adjusted. is there. Also in this embodiment, the same effect as that of the above-mentioned first embodiment can be obtained. Since the left and right straps 11 are independent, the tightening and tightening of the respective straps 11 are independent of each other.

[0011]

[Embodiment 3] The dustproof hood 1 of the embodiment shown in FIG. 6 uses one strap 11 for the main body 2 of the salient type and is attached to the upper rear positions of both ears by a cloth 17 as described above. Pass one strap 11 through the fixed ring 16 and set them in a hooked state, and attach each end of the strap 11 to the position of the lower rear part of each ear with a stopper 15 such as Velcro tape. In this example, the length is adjustable so that it can be detached. Also in this embodiment, the same effect as that of the second embodiment can be obtained.

[0012]

Fourth Embodiment In this embodiment, as shown in FIG. 7, a ring 16 is attached to the upper rear part of both ears of a salient type hood body 2 by a mounting cloth 17, and one end of two straps 11 is attached to both ears. An example in which they are sewn and fixed at lower rear positions, passed through the ring 16 on a diagonal line while being hooked, and connected at the other end after passing through the adjuster 18 in a state in which the length can be adjusted. Is. Also in this embodiment, the same operational effect as that of the third embodiment can be obtained. In this embodiment, the left and right tightening conditions can be adjusted evenly by adjusting the length of the strap 11.

[0013]

[Effect of device]

 In the present invention, a strap is provided on the occipital region of the hood body with the straps slung over and the length of the hood main body is adjustable. Since the length of the circumference can be adjusted at the same time, the degree of close contact between the hood body and the wearer's head is improved, and in particular, the face cloth is in close contact with the face and the mask is in close contact with the nose and mouth around the front side. Therefore, dust generation from the facial opening of the hood body is minimized, and exhaled air does not flow to the ears and neck muscles inside the hood body, so that the worker feels uncomfortable due to the airflow caused by his / her own breathing. You will not feel it.
