Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in conventional trousers, no consideration has been given to the breathability of the waist portion. Generally, when wearing trousers, the trousers are fitted to the wearer's body (waist portion) by tightening a belt etc. so that the trousers do not fall down. Therefore, the breathability of the waist portion inevitably decreases, and there is a problem that it becomes stuffy easily.
[0005] The present invention has been made in view of the above problems, and an object thereof is to provide double - waist pants capable of improving the breathability of the waist portion.
Means for Solving the Problems
[0006] The double-waist pants of the present invention are provided with a double waist portion consisting of an inner waist portion and an outer waist portion at a position corresponding to the wearer's waist, wherein both ends of the inner waist portion are fixed to both ends of the outer waist portion, and the total length of the inner waist portion is shorter than the total length of the outer waist portion.
[0007] In this configuration, a double waistband is provided at the position corresponding to the wearer's waist, and both ends of the inner waistband are fixed to both ends of the outer waistband, respectively, so that the inner waistband is shorter than the outer waistband. Because there is a difference in dimensions between the inner and outer waistbands, a gap can be formed between them, ensuring breathability in the waist area. As a result, the wearer's waist area is less likely to become stuffy.
[0008] Furthermore, in the double-waist pants of the present invention, both ends of the inner waist portion may be sewn to both ends of the outer waist portion, respectively.
[0009] In this configuration, both ends of the inner waistband are sewn to both ends of the outer waistband, respectively, and are securely fixed. Therefore, a gap is likely to form between the inner and outer waistbands due to the difference in dimensions between them.
[0010] Furthermore, in the double-waist pants of the present invention, the double waist portion may be provided at positions corresponding to at least the lateral and rear sides of the wearer's entire waist circumference.
[0011] This configuration ensures breathability at least on the sides and back of the wearer's waist (where the double waistband is provided). This reduces stuffiness in the wearer's waist area.
[0012] Furthermore, in the double-waist pants of the present invention, the double waist portion does not necessarily have to be provided in a position corresponding to the front side of the wearer's entire waist circumference.
[0013] With this configuration, since there is no double waistband on the front side of the wearer's waist, it becomes easy to attach hooks, buttons, and other fasteners that would otherwise be needed on the front side of the waist.
[0014] Furthermore, in the double-waist pants of the present invention, the inner waist portion may be made of a material that has breathability, elasticity, cooling properties, heat retention properties, heat generation properties, blood flow promoting effect, heat insulation properties, waterproofing properties, moisture absorption properties, windproof properties, durability, moisture permeability, antibacterial and deodorizing properties, deodorizing properties, antistatic properties, water absorption and quick drying properties, stain resistance, or far-infrared radiation function.
[0015] This configuration allows for various functions in the inner waistband. For example, making the inner waistband breathable reduces stuffiness around the wearer's waist. Also, making the inner waistband elastic prevents the pants (double-waist pants) from slipping down even without a belt.
[0016] Furthermore, incorporating cooling properties into the inner waistband can cool the wearer's waist, making them feel cooler. Conversely, incorporating heat-retaining properties into the inner waistband can maintain the wearer's waist temperature, making them feel warmer.
[0017] Furthermore, by incorporating heat-generating properties into the inner waistband, the wearer's waist area can be warmed, making them feel warmer. Additionally, by incorporating blood flow-promoting properties into the inner waistband, blood circulation in the wearer's waist area can be improved. Moreover, by incorporating insulating properties into the inner waistband, the temperature inside the garment around the waist can be kept constant, making the wearer feel cool when it's hot and warm when it's cold.
[0018] In addition, if the inner waist part is made waterproof, it can prevent water from seeping in from the wearer's waist part. Also, if the inner waist part is made moisture-absorbent, the wearer's waist part will be less likely to get stuffy. Further, if the inner waist part is made windproof, it can make the wearer feel warm around the waist. Moreover, if the inner waist part is made durable, the wearer's waist part will be less likely to get damaged and will last longer. Additionally, if the inner waist part is made moisture-permeable, the wearer's waist part will be less likely to get stuffy.
[0019] Furthermore, if the inner waist part is made antibacterial and deodorant, it can keep the wearer's waist part cleaner than usual. Also, if the inner waist part is made deodorant, it can suppress the odor of the wearer's waist part.
[0020] Moreover, if the inner waist part is made antistatic, it can suppress the generation of static electricity in the wearer's waist part. Also, if the inner waist part is made water-absorbent and quick-drying, the wearer's waist part can dry quickly even if it gets wet.
[0021] In addition, if the inner waist part is made stain-resistant, it can make the wearer's waist part less likely to get dirty. Also, if the inner waist part is made to have a far-infrared radiation function, it can warm the wearer's waist part with far-infrared rays.
[0022] Also, in the double-waist pants of the present invention, the inner waist part may be provided with a size adjustment part for adjusting the total length of the inner waist part.
[0023] According to this configuration, by adjusting the total length of the inner waist part with the size adjustment part, the size (dimension) of the waist part can be easily adjusted according to the wearer.
Effects of the Invention
[0024] According to the present invention, the breathability of the waist part can be improved.

[Figure 2] This is an explanatory view of the main part of the double-waist pants in the embodiment of the present invention. [Figure 3] This is an explanatory view of the double-waist pants in the embodiment of the present invention (viewed from the upper side of FIG. 1).
Embodiments for Carrying Out the Invention
[0026] Hereinafter, the double-waist pants according to the embodiment of the present invention will be described with reference to the drawings. In this embodiment, the case of double-waist pants used as cargo pants or the like is exemplified.
[0027] The configuration of the double-waist pants according to the embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of the double-waist pants according to this embodiment. Also, FIG. 2 is an explanatory view of the main part of the double-waist pants according to this embodiment. Also, FIG. 3 is an explanatory view of the double-waist pants according to this embodiment (viewed from the upper side of FIG. 1).
[0028] As shown in FIGS. 1 and 2, the double-waist pants 1 according to this embodiment are provided with a double-waist part 4 composed of an inner waist part 2 and an outer waist part 3 at a position corresponding to the waist of the wearer. Both ends 20 of the inner waist part 2 are sewn and fixed to both ends 30 of the outer waist part 3 respectively.
[0029] As shown in FIG. 2, the inner waist part 2 is provided with a size adjustment part 5 for adjusting the entire length of the inner waist part 2. In this embodiment, the size adjustment part 5 is composed of a stopper and a cord. After adjusting the size (dimension) of the waist part by pulling the cord, it is fixed with the stopper. Note that the size adjustment part 5 is not limited to being composed of a stopper and a cord, and known techniques can be used.
[0030] As shown in Figure 3, the double waist portion 4 is provided at positions corresponding to at least the lateral PS and posterior PB sides of the wearer's waist circumference. In this case, the double waist portion 4 is not provided at positions corresponding to the front PF side of the wearer's waist circumference. Furthermore, the total length of the inner waist portion 2 is configured to be shorter than the total length of the outer waist portion 3. For example, if the total length (dimension) of the outer waist portion 3 is 86 cm, the total length (dimension) of the inner waist portion 2 is configured to be 76 cm.
[0031] In this embodiment, the inner waist portion 2 can be made of various materials. For example, the inner waist portion 2 can be made of a breathable material such as mesh material. Alternatively, the inner waist portion 2 can be made of an elastic material such as rubber material. Furthermore, by making the inner waist portion 2 out of a material such as mesh material and inserting an elastic cord into the inner waist portion 2, both breathability and elasticity can be provided to the inner waist portion 2. The elasticity of the inner waist portion 2 provides ease of putting on and taking off, as well as a pressure distribution function that prevents the load from concentrating at one point. In addition, the mesh material has moisture permeability that releases moisture from inside the garment to the outside.
[0032] Furthermore, the inner waistband 2 can be constructed from a material with cooling properties, such as a fabric made with PCM material (Phase Change Material). Alternatively, the inner waistband 2 can be constructed from a material with heat retention properties, such as a fabric made with aluminum.
[0033] Furthermore, the inner waistband 2 can be made of a material with heat-generating properties, such as an acrylic or rayon fabric. The inner waistband 2 can also be made of a material with blood flow-promoting effects, such as a fabric mixed with capsaicin. Furthermore, the inner waistband 2 can be made of a material with heat-insulating properties, such as a fabric using cellulose fiber or aerogel.
[0034] Furthermore, the inner waistband 2 can be made of a waterproof material, such as a fabric coated or laminated with a waterproof film. The inner waistband 2 can also be made of a moisture-absorbing material, such as a polyester or nylon fabric. The inner waistband 2 can also be made of a windproof material, such as a fabric coated with acrylic or polyester. Furthermore, the inner waistband 2 can be made of a durable (abrasion-resistant) material, such as nylon fabric.
[0035] Furthermore, the inner waistband 2 can be made of a material with antibacterial and deodorizing properties, such as fabric treated with antibacterial and deodorizing processing. Antibacterial and deodorizing properties can also be provided by attaching antibacterial and deodorizing tape to the inner waistband 2. Additionally, the inner waistband 2 can be made of a material with deodorizing properties, such as fabric treated with deodorizing processing. Deodorizing properties can also be provided by attaching deodorizing tape to the inner waistband 2.
[0036] Furthermore, the inner waistband 2 can be made of a material with antistatic properties, such as fabric using antistatic yarn or fabric treated with antistatic processing. Antistatic properties can also be added by attaching antistatic tape to the inner waistband 2. Additionally, the inner waistband 2 can be made of a material with moisture-wicking and quick-drying properties, such as fabric treated with moisture-wicking and quick-drying processing. Moisture-wicking and quick-drying properties can also be added by attaching moisture-wicking and quick-drying tape to the inner waistband 2.
[0037] Furthermore, the inner waistband 2 can be constructed from a stain-resistant material, such as a stain-resistant fabric. Additionally, the inner waistband 2 can be constructed from a material with far-infrared radiation properties, such as a fabric with an aluminum print finish or a fabric using volcanic ash or graphite.
[0038] In this embodiment of the double-waist pants 1, a double waist portion 4 is provided at a position corresponding to the wearer's waist, and both ends 20 of the inner waist portion 2 of the double waist portion 4 are fixed to both ends 30 of the outer waist portion 3, respectively, so that the inner waist portion 2 is shorter than the outer waist portion 3. Because there is a difference in dimensions between the inner waist portion 2 and the outer waist portion 3, a gap S can be formed between the inner waist portion 2 and the outer waist portion 3 (see Figure 3), ensuring breathability in the waist area. As a result, the wearer's waist area is less likely to become stuffy.
[0039] Furthermore, in this embodiment, both ends 20 of the inner waist portion 2 are sewn to both ends 30 of the outer waist portion 3, respectively, and are securely fixed. As a result, a gap S is easily formed between the inner waist portion 2 and the outer waist portion 3 due to the difference in dimensions between them (see Figure 3).
[0040] Furthermore, in this embodiment, breathability can be ensured at least on the sides and back of the wearer's waist (the positions where the double waist portion 4 is provided). This makes the wearer's waist less prone to stuffiness.
[0041] Furthermore, in this embodiment, since the double waist portion 4 is not provided on the front side of the wearer's waist, it becomes easy to provide hooks, buttons, and other fasteners that need to be provided on the front side of the waist.
[0042] Furthermore, in this embodiment, the inner waist portion 2 can be given various functions. For example, if the inner waist portion 2 is made breathable, the wearer's waist area will be less likely to get sweaty. Also, if the inner waist portion 2 is made elastic, the pants (double-waist pants) will be less likely to slip down even without a belt.
[0043] Furthermore, if the inner waistband 2 has cooling properties, it can cool the wearer's waist area, making it feel cool. Also, if the inner waistband 2 has heat-retaining properties, it can maintain the temperature of the wearer's waist area, making it feel warm.
[0044] Furthermore, by giving the inner waist portion 2 a heat-generating effect, it can warm the wearer's waist area, making them feel warm. Additionally, by giving the inner waist portion 2 a blood flow promoting effect, it can improve blood flow to the wearer's waist area. Furthermore, by giving the inner waist portion 2 an insulating effect, it can maintain a constant temperature inside the garment around the waist, making the wearer feel cool when it's hot and warm when it's cold.
[0045] Furthermore, making the inner waistband 2 waterproof prevents water from seeping in from the wearer's waist. Also, making the inner waistband 2 moisture-wicking reduces stuffiness around the wearer's waist. Furthermore, making the inner waistband 2 windproof makes the waist feel warmer. Furthermore, making the inner waistband 2 durable makes the wearer's waist less prone to damage and lasts longer. Furthermore, making the inner waistband 2 breathable reduces stuffiness around the wearer's waist.
[0046] Furthermore, by giving the inner waistband 2 antibacterial and deodorizing properties, the wearer's waist area can be kept cleaner than usual. Also, by giving the inner waistband 2 deodorizing properties, odors around the wearer's waist can be suppressed.
[0047] Furthermore, by giving the inner waistband 2 antistatic properties, static electricity can be suppressed around the wearer's waist. Also, by giving the inner waistband 2 moisture-wicking and quick-drying properties, the wearer's waist can dry quickly even if it gets wet.
[0048] Furthermore, by making the inner waistband 2 stain-resistant, the wearer's waist area can be made less prone to getting dirty. Also, by making the inner waistband 2 far-infrared radiation function, the wearer's waist area can be warmed with far-infrared rays.
[0049] Furthermore, in this embodiment, the size (dimensions) of the waist portion can be easily adjusted to suit the wearer by adjusting the overall length of the inner waist portion 2 using the size adjustment section 5.
[0050] Although embodiments of the present invention have been described above by example, the scope of the present invention is not limited to these, and modifications and alterations can be made within the scope described in the claims depending on the purpose.
[0051] For example, the above embodiment describes an example in which buttons are provided on the front side of the double-waist pants 1, but the scope of the present invention is not limited to this, and the invention can be similarly implemented even if buttons are not provided on the front side of the double-waist pants 1.
