Mode for Carrying Out the Invention

[0013] Hereinafter, the protective garment X according to each embodiment of the present invention will be described with reference to the drawings. The description will be detailed in the order of the configuration of the embodiment, the method of implementation, and other examples. Note that each of the embodiments shown below is an example of the present invention, and the present invention is not limited to the following embodiments.

[0014] ≪First Embodiment≫ The fabric of the protective garment X according to this example is formed in a laminated structure of an outer layer 1, a waterproof layer 2, a heat-insulating layer 3, and a ventilation layer 4. FIG. 1 shows a schematic diagram of the laminated structure, FIG. 2 shows a schematic diagram of the configuration of the holding portion 41 included in the ventilation layer 4, and FIG. 3 shows a schematic diagram of the overall shape of the protective garment X and a schematic diagram showing the holding portion 41 with a part thereof cut out. In the following description, "outer side" and "inner side" are based on the axis shown in FIG. 1, and "upper" and "lower" are based on the axis shown in FIG. 3.

[0015] The outer layer 1 is a fabric material composed of a fire-resistant, heat-resistant, and flame-retardant woven fabric that forms the outermost layer of the protective garment X, and maintains the shape of the protective garment X with a certain thickness and strength. Also, in a high-temperature environment, if the protective garment X contains moisture, its heat protection function may be impaired, or the weight of the entire protective garment X may increase, impairing the mobility of the user. Therefore, the outer layer 1 is preferably composed of a water-repellent material.

[0016] The waterproof layer 2 is a fabric material provided immediately inside the outer layer 1, and prevents moisture from entering from the outside to the inside of the protective garment X. Also, the waterproof layer 2 is preferably composed of a heat-resistant and flame-retardant woven fabric or non-woven fabric, and in particular, a configuration including a semi-permeable membrane that allows water vapor to pass through but does not allow liquid water to pass through is preferred. With such a configuration, moisture inside the protective garment X generated when the user sweats and evaporates can escape to the outside of the protective garment X.

[0017] The heat insulation layer 3 is a heat-insulating fabric material that forms the innermost layer of the protective clothing X, and is integrally formed in a multi-layer structure of a non-woven fabric and a woven fabric of flame-retardant fibers. In this multi-layer structure, in particular, the layer of the woven fabric is provided on the inner side. With such a configuration, the wearing feeling of the portion contacting the user's body can be improved.

[0018] The ventilation layer 4 is a layer containing a large amount of air provided between the waterproof layer 2 and the heat insulation layer 3, and is a portion held by the separation of the waterproof layer 2 and the heat insulation layer 3 as shown in FIG. 1. The ventilation layer 4 is formed by sewing the outer edges of the waterproof layer 2 and the heat insulation layer 3 to each other to be connected in a bag shape, or by detachably providing the heat insulation layer 3 from the waterproof layer 2. However, by itself, it cannot maintain the thickness of the internal air (the state where the waterproof layer 2 and the heat insulation layer 3 are separated), so as shown in FIG. 1, a holding portion 41 is provided.

[0019] Also, the ventilation layer 4 is provided inside the waterproof layer 2 to prevent the heat insulation efficiency from decreasing due to the intrusion of moisture. In addition, the influence of the high-temperature outside air to which the outer layer 1 is exposed is reduced by the internal air, and the heat insulation performance of the entire protective clothing X is improved.

[0020] The holding portion 41 is a structure including a member that holds the thickness direction of the ventilation layer 4, that is, the length in the outer - inner direction shown in FIG. 1, and has flexibility that can be easily bent by a person's hand. With such a configuration, an air layer is surely formed between the layers of the protective clothing X, making it easier to move when worn. Also, since air can easily move inside the ventilation layer 4, heat transfer from the outside is delayed, and the heat insulation performance of the protective clothing X can be improved.

[0021] The holding part 41 is a three-dimensional structure with a mesh structure formed by a first layer 411, a second layer 412, and a holding member 413. With such a configuration, the thickness of the ventilation layer 4 can be stably maintained. As shown in FIG. 1, one of the first layer 411 and the second layer 412 is provided in surface contact with the waterproof layer 2, and the other is sewn so as to be in surface contact with the heat insulation layer 3. The holding member 413 is provided between the first layer 411 and the second layer 412. With such a configuration, the thickness of the ventilation layer 4 can be maintained. Also, the holding part 41 is preferably made of a heat-resistant material or a wear-resistant material. Examples of this include aramid fiber, polyester fiber, carbon fiber, etc.

[0022] The first layer 411 and the second layer 412 are sheet-like members formed parallel to each other and are formed in a mesh shape as shown in FIG. 2. With such a configuration, not only can the deformation of the entire holding part 41 be made easier, but also the friction can be reduced at the respective contact surfaces between the first layer 411 and the waterproof layer 2, and the second layer 412 and the heat insulation layer 3 (a combination of the first layer 411 and the heat insulation layer 3, and the second layer 412 and the waterproof layer 2 may also be used), making it easier for the entire protective clothing X to deform.

[0023] The holding member 413 is a member provided in a large number so as to connect between the first layer 411 and the second layer 412, and holds the first layer 411 and the second layer 412 so as to be separated. The holding member 413 has flexibility that can be easily bent and crushed by a human hand and elasticity that can restore its shape. With such a configuration, both the maintenance of the thickness of the ventilation layer 4 and the improvement of the wearing feeling of the protective clothing X can be achieved.

[0024] The holding member 413 is a fibrous member having flame retardancy or heat resistance with elasticity in the bending direction, and forms a mesh structure together with the first layer 411 and the second layer 412. At this time, the fibers forming the holding member 413 are woven into the first layer 411 and the second layer 412 and are provided in a shape such as a wave or a backstitch so as to regularly move back and forth between the two. Furthermore, an appropriate gap is provided between the fibers connecting the layers, thereby allowing the air in the ventilation layer 4 to move easily.

[0025] Since the holding member 413 is made of an elastic material (such as surface-treated polyester fibers), the holding portion 41 can absorb the impact applied to the protective garment X. Further, this can reduce the sense of weight and pressure when wearing the protective garment X.

[0026] The protective garment X is a piece of clothing including a front body X1, a back body X2, and sleeves X3, and the fabric material constituting each part has a multi-layer structure of the outer layer 1, the waterproof layer 2, the heat-insulating layer 3, and the ventilation layer 4 as described above. Herein, the holding portion 41 is provided in a part of the ventilation layer 4.

[0027] As shown in FIG. 3, the holding portion 41 is preferably configured to be provided in an upper side of the body of the protective garment X, particularly in the shoulder area or the like, in a range where the load due to the weight is directly applied to the user's body. More preferably, the range where the holding portion 41 is provided is a range that extends from the root portion of the collar toward the left and right sleeves X3, and in the vertical direction, in both the body and the sleeves X3, when closing the sides, it is a range where the same height as the side is the lower limit. Even more preferably, the lower end portion of the holding portion 41 in the vertical direction is configured to be arranged near the middle in the vertical direction of the boundary portion between the body and the sleeves X3. With such a configuration, while suppressing an increase in the weight of the entire protective garment X by the holding portion 41, the sense of weight when wearing the protective garment X can be reduced. Further, the holding portion 41 may be provided so as to protrude from the left and right sleeves X3.

[0028] ≪Modification Example≫ The first layer 411 and the second layer 412 are formed in the same shape, but one may be mesh-like and the other may be a sheet material. With such a configuration, the shape of the entire holding portion 41 is likely to be stable.

[0029] The holding portion 41 may be configured not to have one or both of the first layer 411 and the second layer 412, and the holding member 413 may be formed by being intertwined in a cotton-like manner while winding a spiral. With such a configuration, the holding portion 41 can move more flexibly, and the mobility of the user when wearing is improved.

[0030] The holding part 41 is preferably provided not only around the shoulders of the protective clothing X but also near the middle of the left and right sleeves X3, particularly at a portion covering the elbows of the user. With such a configuration, even if the elbows of the user hit surrounding objects, the holding part 41 can absorb the impact and reduce the possibility of injury. Similarly, the holding part 41 may be provided at movable parts such as around the joints of the user or in a range where important organs such as the chest can be protected.

[0031] In FIG. 2, the first layer 411 and the second layer 412 show a configuration in which regular hexagons are continuous, but other shapes, for example, a mesh structure with circular openings or a mesh structure with continuous rhombuses may also be used. With such a configuration, the contact area with the waterproof layer 2 and the heat insulation layer 3 is reduced compared to a sheet-like fabric material without openings, and friction and the resulting wear of the holding part 41 can be suppressed.

[0032] In the description of this embodiment, as shown in FIG. 3, an upper garment is cited as the protective clothing X including the holding part 41, but other clothing such as trousers may also be made of the fabric having the laminated structure shown in FIG. 1. For example, in the case of trousers, a configuration is assumed in which the ventilation layer 4 has the holding part 41 in the part below the knees that does not overlap with the upper garment when worn. With such a configuration, the heat insulation property of the protective clothing X can be improved and the user's lower body can be protected, and it is also possible to absorb impacts around the knees.

[0033] Hereinafter, the method of implementation of the present invention will be described in detail with reference to the drawings. The present invention is implemented by a user (mainly a firefighter or a factory worker) wearing the protective clothing X. Also, the method of implementation shown below is an example, and the method of implementation is not limited to this, and the order may be reversed.

[0034] ≪Method of Implementation≫ The protective clothing X is used as a fire-fighting suit. The user wears the protective clothing X over the inner or underwear and goes to the fire scene. At this time, the heat of the fire is transmitted from the outside shown in FIG. 1, but since the heat conduction is delayed by the ventilation layer 4, the user can work at the fire scene for a long time.

[0035] In addition to being a fireproof suit, the protective clothing X is also used as protective clothing at sites where high temperatures and high heat are expected, such as factories. The user wears the protective clothing X and works in a high-temperature work space such as around a blast furnace. At this time, since the heat conduction of the blast furnace is retarded by the ventilation layer 4, the user can work at the fire site for a long time.

[0036] Hereinafter, the protective clothing X according to the second embodiment of the present invention will be described with reference to the drawings. For the same configurations as those in the first embodiment, the same reference numerals will be used and the description thereof will be omitted. In the following description, "outer side" and "inner side" conform to the axis shown in FIG. 4.

[0037] ≪Second Embodiment≫ As shown in FIG. 4, the cloth material forming the protective clothing X according to the present embodiment has a multi-layer structure including, in order from the outside, an outer layer 1, a ventilation layer 4, and a composite layer 5. The composite layer 5 is a layer in which the waterproof layer 2 and the heat insulation layer 3 in the first embodiment are integrated.

[0038] The ventilation layer 4 is a heat insulation layer provided between the outer layer 1 and the composite layer 5, and is provided with a holding portion 41 to maintain the thickness between the layers. With such a configuration, since air can easily move inside the ventilation layer 4, the heat insulation property of the protective clothing X can be improved.

[0039] The holding portion 41 is a three-dimensional structure formed by a first layer 411, a second layer 412, and a holding member 413. As shown in FIG. 4, one of the first layer 411 and the second layer 412 is provided in surface contact with the outer layer 1, and the other is provided in surface contact with the composite layer 5, and the holding member 413 is provided between the first layer 411 and the second layer 412. With such a configuration, the thickness of the ventilation layer 4 can be maintained.
