[0003] [Patent Document 1] JP 2019-189954 A Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned dustproof hood can reduce the scattering of the wearer's hair, dust, and other foreign matter from the internal space of the hood body to the external space, and can be easily worn. However, the above-mentioned dustproof hood does not satisfy the wearer's desire to feel cool.

[0005] Therefore, it has been considered to attach a fan to the dustproof hood so that the wearer can feel cool. However, simply attaching a fan to the dustproof hood does not allow the air taken in from the outside by the fan to reach the area around the top of the wearer's head. Therefore, there is a problem that simply attaching a fan to the dustproof hood is still insufficient to provide the wearer with a feeling of coolness.

[0006] In view of the above problems, the present invention has an object to provide a dustproof hood that allows the wearer to feel cool. [Means for solving the problem]

[0007] The above object of the present invention can be achieved by the following means. Note that the parentheses indicate reference symbols of the embodiments described below, but the present invention is not limited thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] Hereinafter, an embodiment of a dustproof hood according to the present invention will be described in detail with reference to the drawings. In the following description, when directions such as up, down, left, and right are indicated, they refer to up, down, left, and right when viewed from the front in the drawings.

[0021] <Outline of the dustproof hood> The dustproof hood according to this embodiment is used in factories that manufacture food, medicines, etc., clean rooms that manufacture semiconductors, etc., and allows the wearer to feel cool and cool. Specifically, as shown in Figs. 1 to 3, the dustproof hood 1 includes a hood body 2. The hood body 2 will be described below.

[0022] <Description of the hood body> The hood body 2 is made of a fabric made of chemical fibers such as polyurethane and polyester that is soft to the touch and has elasticity, and is designed to cover the entire head and neck of the wearer (not shown). As shown in FIG. 1, the hood body 2 has a front side cloth 20 at the lower center side when viewed from the front. As shown in FIG. 1, a right front side cloth 21a is sewn to the right side of the front side cloth 20, and a left front side cloth 21b is sewn to the left side of the front side cloth 20. As shown in FIG. 1, a right rear side cloth 22a is sewn to the right side of the right front side cloth 21a, and a left rear side cloth 22b is sewn to the left side of the left front side cloth 21b. The right rear side cloth 22a and the left rear side cloth 22b are provided to extend from the front side (the front side shown in FIG. 1) to the rear side (the back side shown in FIG. 2) as shown in FIGS. 1 and 2.

[0023] On the other hand, as shown in Fig. 1, a right head side cloth 23a is sewn to the upper surfaces of the right front side cloth 21a and the right rear lateral side cloth 22a, and a left head side cloth 23b is sewn to the upper surfaces of the left front side cloth 21b and the left rear lateral side cloth 22b. The right head side cloth 23a and the left head side cloth 23b are provided extending from the front side (the front side shown in Fig. 1) to the rear side (the rear side shown in Fig. 2) as shown in Figs. 1 and 2.

[0024] 1, a central head / occipital cloth 24 is sewn to the left side surface of the right head side cloth 23a and the right side surface of the left head side cloth 23b. The central head / occipital cloth 24 extends to the rear side (the back side shown in FIG. 2) as shown in FIG. 2, and is sewn to the right side surface of the right rear lateral side cloth 22a and the left side surface of the left rear lateral side cloth 22b.

[0025] Thus, the hood body 2 formed in this manner is provided with an elliptical opening window 3 formed penetrating the inside and outside of the hood body 2 at approximately the center when viewed from the front, as shown in Fig. 1. This opening window 3 is sized to allow the wearer's face to be exposed, and as shown in Fig. 3, a fastener 3b is sewn to a peripheral edge portion 3a so that a transparent resin shield (not shown), which is a conventionally well-known configuration, can be attached.

[0026] 1 to 3, a hood skirt 4 is sewn to the lower part of the hood body 2, i.e., to the front side cloth 20, and the right front side cloth 21a and the left front side cloth 21b, as well as the right rear lateral side cloth 22a and the left rear lateral side cloth 22b, and the undersides of the central head and rear head cloth 24. The hood skirt 4 is a cape that covers the shoulders of the wearer.

[0027] Incidentally, the characteristic feature of this embodiment is the portion relating to the central head and rear head cloth 24, and therefore this point will be described in detail below.

[0028] <Explanation about the central head and back of the head cloth> As shown in FIG. 2, the central head / occipital cloth 24 is provided with an air conditioning hole 5, which is a circular through-hole formed penetrating the inside and outside of the hood body 2, at a substantially central position when viewed from the back. A fan (not shown) having a conventionally known configuration capable of taking in air K (see FIG. 4) outside the hood body 2 into the hood body 2 is attached to this air conditioning hole 5. As shown in FIG. 2, a mesh-like fabric 6 is provided in this air conditioning hole 5 so as to cover the entire air conditioning hole 5. As shown in FIG. 2, this mesh-like fabric 6 is formed in a rectangular shape, and the upper side surface 6a and the lower side surface 6b are sewn to the central head / occipital cloth 24 along the width direction (left-right direction in the figure) of the central head / occipital cloth 24. Furthermore, as shown in FIG. 2, the left side surface 6c of the mesh-like fabric 6 is sewn to the right side surface of the right rear lateral side surface cloth 22a, and the right side surface 6d of the mesh-like fabric 6 is sewn to the left side surface of the left rear lateral side surface cloth 22b. Thus, the mesh-like fabric 6 is provided so as to cover the entire air conditioning hole 5 as shown in FIG. 2. As a result, as shown in FIG. 4, air K outside the hood body 2 can be taken into the inside of the hood body 2 by a fan (not shown) through the mesh fabric 6 (see the direction of the arrow Y1). On the other hand, even if a foreign object tries to go out of the hood body 2 through the fan (not shown) for some reason, the foreign object can be captured by the mesh fabric 6. Therefore, it is possible to prevent the foreign object from going out of the hood body 2. Therefore, by providing such a mesh fabric 6, it is possible to take in air K outside the hood body 2 into the inside of the hood body 2 by the fan (not shown), and it is also possible to prevent the scattering of foreign objects. Therefore, such a configuration is particularly useful for use in factories that manufacture food, medicine, etc., and clean rooms that manufacture semiconductors, etc.

[0029] Incidentally, if a fan (not shown) is used to take in air K (see FIG. 4) from outside the hood body 2 into the inside of the hood body 2, the wearer can feel a certain degree of coolness. However, this alone is not enough to deliver that air to the area near the top of the wearer's head.

[0030] Therefore, in this embodiment, as shown in FIG. 4, an introduction section 7 is provided inside the hood body 2. This introduction section 7 is formed of a substantially rectangular fabric different from the fabric of the hood body 2. Specifically, it is made of a fabric that is breathable and stretchable, and is made of very finely woven polyester fibers knitted by warp knitting such as tricot. As shown in FIG. 4, this introduction section 7 is provided along the inner peripheral wall surface 24a of the central head and rear head cloth 24 from the air conditioning hole 5 side to the wearer's head top side. Furthermore, as shown in FIG. 4, the introduction section 7 provided in this manner is configured to form a gap S between the introduction section 7 and the inner peripheral wall surface 24a of the central head and rear head cloth 24. To form this gap S, the left and right side surfaces of the introduction section 7 are sewn to the inner peripheral wall surface 24a of the central head and rear head cloth 24, thereby forming the gap S. The upper end 7a and the lower end 7b of the introduction section 7 shown in FIG. 4 are open.

[0031] Incidentally, the lower end 7b of the introduction portion 7 shown in FIG. 4 is a hook-and-loop fastener, and can be attached to and detached from the hook-and-loop fastener 24b sewn to the inner peripheral wall surface 24a of the central head / occipital head cloth 24. Therefore, the lower end 7b of the introduction portion 7 can be opened and closed by the hook-and-loop fastener. Therefore, when attaching or removing a fan (not shown) to the air conditioning hole 5, the lower end 7b of the introduction portion 7 is opened, and the fan (not shown) is inserted into the gap S, and then attached to or removed from the air conditioning hole 5. Then, after completing such an operation, the lower end 7b of the introduction portion 7 is closed by the hook-and-loop fastener.

[0032] Thus, by providing such an introduction section 7, it is possible to send the taken-in air to the vicinity of the top of the wearer's head. That is, as shown in FIG. 4, the air K (see the direction of the arrow Y1) outside the hood body 2 taken into the inside of the hood body 2 by a fan (not shown) is guided to the top of the wearer's head through the gap S due to the introduction section 7 (see the direction of the arrow Y2). Then, the guided air K is output from the upper end portion 7a of the introduction section 7 (see the direction of the arrow Y3) as shown in FIG. 4. As a result, the air K can be sent to the vicinity of the top of the wearer's head, so that the wearer can feel cool. Furthermore, since the introduction section 7 uses a breathable material, the air K also moves slightly through the introduction section 7 to the space S1 side shown in FIG. 4. As a result, the back of the wearer's head is cooled, so that the wearer can feel even cooler.

[0033] However, since the central head / occipital back cloth 24 is not made of a material that can maintain its shape, the inner peripheral wall surface 24a of the central head / occipital back cloth 24 may be dented, which may crush the gap S formed between the central head / occipital back cloth 24 and the introduction portion 7. If the gap S is crushed, the passage of the air K is blocked, and the air K cannot be sent to the vicinity of the top of the wearer's head. As a result, the wearer cannot feel cool.

[0034] Therefore, in this embodiment, in order to maintain the shape of the central head and rear head cloth 24, as shown in FIG. 4, a shape-retaining member 8 is provided on the central head and rear head cloth 24. As shown in FIGS. 1 to 4, a plurality of shape-retaining members 8 are provided at appropriate intervals from the air conditioning hole 5 side toward the front side (top of the wearer's head). More specifically, as shown in FIGS. 5(a) and (b), the shape-retaining member 8 has a cylindrical bag body 8a. The bag body 8a is made of the same fabric as the fabric of the hood body 2, and is provided in the width direction of the central head and rear head cloth 24 (left and right direction shown in FIGS. 1 and 2) by being sewn to the inner peripheral wall surface 24a of the central head and rear head cloth 24 as shown in FIGS. 5(a) and (b). As a result, a plurality of shape-retaining members 8 are provided at appropriate intervals from the air conditioning hole 5 side toward the front side (top of the wearer's head) as shown in FIGS. 1 to 4.

[0035] Then, as shown in Figures 5(a) and (b), a core material 8b such as bone tape is inserted into the bag body 8a. After inserting the core material 8b into the bag body 8a, the opening portion is sewn to the inner peripheral wall surface 24a of the central head and occipital cloth 24. Also, the tip end surface 8b1 (see Figure 5(c)) and the base end surface of the core material 8b are formed into an R-shape as shown in Figure 5(c) so as not to tear the bag body 8a.

[0036] Thus, the shape-retaining member 8 configured as described above includes the core material 8b, which can retain the shape of the central head / occipital cloth 24. This reduces the possibility that the inner peripheral wall surface 24a of the central head / occipital cloth 24 will be recessed and the gap S formed between the introduction portion 7 will be crushed.

[0037] Therefore, according to the present embodiment described above, the wearer can feel a cool sensation.

[0038] Furthermore, as explained above, if the shape of the central head and back head cloth 24 is maintained, the appearance of the hood body 2 can be improved.

[0039] In addition, in this embodiment, as described above (see FIG. 4), the air K outside the hood body 2 is sent to the vicinity of the top of the wearer's head, so that the transparent resin shield (not shown) can be prevented from fogging. That is, in the dustproof hood 1 to which the transparent resin shield (not shown) can be attached, the inside of the dustproof hood 1 is sealed, so that if the air circulation is poor, not only will the wearer not feel cool, but the transparent resin shield (not shown) will become fogged up. Therefore, as described in this embodiment, if the air K outside the hood body 2 is sent to the vicinity of the top of the wearer's head, the air K will flow toward the transparent resin shield (not shown), so that not only will the wearer feel cool, but the transparent resin shield (not shown) can also be prevented from fogging up.

[0040] In this embodiment, as shown in FIG. 5(a), an introduction part shape retaining member 9 is provided at the upper end 7a of the introduction part 7. This introduction part shape retaining member 9 retains the shape of the upper end 7a of the introduction part 7. That is, if the upper end 7a of the introduction part 7 is in close contact with the inner peripheral wall surface 24a of the central head and occipital head cloth 24 and blocks the opening, the air K (see the direction of the arrow Y3) shown in FIG. 4 cannot be output from the upper end 7a of the introduction part 7. Therefore, in this embodiment, in order to avoid such a situation, the introduction part shape retaining member 9 is provided at the upper end 7a of the introduction part 7 to retain the shape of the upper end 7a of the introduction part 7. As shown in FIG. 5(a), this introduction part shape retaining member 9 has a cylindrical bag body 9a. This bag body 9a is made of the same fabric as the fabric of the introduction part 7 and is sewn to the upper end 7a of the introduction part 7. Then, a core material 8b such as a bone tape is inserted into such a bag body 9a as shown in FIG. 5(a). After inserting the core material 8b into the bag body 9a, the opening portion is sewn to the upper end portion 7a of the introduction portion 7.

[0041] Thus, the introduction portion shape-retaining member 9 is provided with the core material 8b, which can maintain the shape of the upper end portion 7a of the introduction portion 7. This makes it possible to reduce the situation in which the upper end portion 7a of the introduction portion 7 is in close contact with the inner peripheral wall surface 24a of the central head / occipital region cloth 24 and blocks the opening.

[0042] <Description of Modifications> The shapes and the like shown in this embodiment are merely examples, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims. For example, in this embodiment, the shape-retaining member 8 is provided by sewing it to the inner peripheral wall surface 24a of the central head and rear head cloth 24, but the present invention is not limited to this, and it may be sewn to the outer peripheral wall surface of the central head and rear head cloth 24. Also, it may be provided on both the inner peripheral wall surface 24a of the central head and rear head cloth 24 and the outer peripheral wall surface of the central head and rear head cloth 24.

[0043] In addition, in this embodiment, an example has been shown in which multiple shape retaining members 8 are provided at appropriate intervals from the air conditioning hole 5 side toward the front side (the wearer's top of the head), but this is not limiting, and the shape retaining members 8 may be provided only on the air conditioning hole 5 side and the wearer's top of the head. However, it is preferable to provide multiple shape retaining members 8 from the air conditioning hole 5 side toward the front side (the wearer's top of the head) as in this embodiment. This is because it is possible to further reduce the possibility that the inner peripheral wall surface 24a of the central head / occipital head cloth 24 will be recessed and the gap S formed between the introduction part 7 will be crushed.

[0044] Furthermore, in this embodiment, an example has been shown in which the bag body 8a is made of the same fabric as the fabric of the hood body 2, but the present invention is not limited to this, and the bag body 8a may be made of a different fabric.

[0045] In addition, in the present embodiment, an example has been shown in which the bag body 9a is made of the same fabric as the introduction portion 7, but the present invention is not limited to this, and the bag body 9a may be made of a different fabric.

[0046] In addition, in the present embodiment, an example in which a plurality of shape-retaining members 8 are provided has been shown, but the present invention is not limited to this, and a single shape-retaining member may be used. For example, in the case of a single shape-retaining member, a bag body of a size extending from the air conditioning hole 5 side toward the front side (the wearer's top side) may be prepared, and a core material matching the size may be inserted into the bag body.

[0047] Furthermore, the shape of the shape-retaining member 8 illustrated in this embodiment is merely an example, and it may be arranged in a cross shape or a rectangular shape, or any shape is acceptable as long as it can retain the shape of the central head and occipital cloth 24.

[0048] In addition, in this embodiment, an example has been shown in which an introduction portion shape-retaining member 9 is provided at the upper end portion 7a of the introduction portion 7, but if unnecessary, it does not have to be provided, and the introduction portion shape-retaining member 9 may be provided other than at the upper end portion 7a of the introduction portion 7.

[0049] Furthermore, in this embodiment, an example has been shown in which the shape of the central head and back head cloth 24 is maintained, but if necessary, other cloths may be maintained.

[0050] In addition, in this embodiment, an example has been shown in which the core material 8b is inserted into the bags 8a and 9a, but the shape retaining member 8 and the introduction portion shape retaining member 9 may be configured only with the core material 8b. However, since there is a possibility of problems occurring, such as the wearer being injured when wearing the garment, or the shape retaining member 8 and the introduction portion shape retaining member 9 not being able to be firmly fixed in position, it is preferable to insert the core material 8b into the bags 8a and 9a.

[0051] In addition, in this embodiment, an example is shown in which a dustproof hood 1 is fitted with a transparent resin shield (not shown), which is a conventionally well-known configuration, but the present invention is not limited to this and can also be applied to dustproof hoods in which such a shield cannot be attached.
