Abstract
Description
[Technical Field]
[0001] This specification discloses a technique relating to loincloth-type pants. [Background technology]
[0002] The loincloth-type pants are made by bridging the pants body from the front side to the rear side of the waist belt. Patent Document 1 describes loincloth-type pants made by bridging the pants body from the front side to the rear side of the waist belt. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-73201 Summary of the Invention [Problem to be solved by the invention]
[0004] The fundoshi-style pants of Patent Document 1 have a problem in that the front and back body sections of the pants are the same shape, which can cause a mismatch in fit and make the wearer feel uncomfortable. [Means for solving the problem]
[0005] One form of fundoshi-style pants disclosed in this specification comprises a waist belt made of elastic strips of fabric connected in a ring shape and worn around the waist of a wearer; and a pants body connected to the front lower part and rear lower part of the waist belt, covering the wearer's lower abdomen, crotch, and buttocks. The pants body has a front body section extending from the front lower part to the crotch, and a back body section extending from the rear lower part to the crotch. A first connection section connecting the front body section to the waist belt and a second connection section connecting the back body section to the waist belt are spaced apart. The surface area of the back body section is larger than that of the front body section. The front body section has at least one pair of tucks on either side of the horizontal center. With this form of fundoshi-style pants, the surface area of the back body section, which covers the buttocks, which are wider than the lower abdomen, is larger than that of the front body section, while the pair of tucks in the front body section provide ample space from the lower abdomen to the crotch area. As a result, this type of loincloth-type pants can improve the wearing comfort. [Brief explanation of the drawings]
[0006] [Figure 1] FIG. 1 is a perspective view showing loincloth-type pants. [Figure 2] FIG. 1 is a front view showing loincloth-type pants. [Figure 3] FIG. 1 is a rear view showing the loincloth-type pants. DETAILED DESCRIPTION OF THE INVENTION
[0007] FIG. 1 is a perspective view showing the fundoshi-type pants 100. FIG. 2 is a front view showing the fundoshi-type pants 100. FIG. 3 is a back view showing the fundoshi-type pants 100. The fundoshi-type pants 100 are men's underwear. The fundoshi-type pants 100 include a waist belt 110 and a pants body 120.
[0008] The waist belt 110 of the loincloth-type pants 100 is made by connecting elastic strips of fabric in a circular shape. The waist belt 110 is worn around the waist of the wearer.
[0009] The pants body 120 of the loincloth-type pants 100 is a fabric that covers the wearer's lower abdomen, crotch, and buttocks. The pants body 120 is connected to the front lower portion 111 and the back lower portion 112 of the waist belt 110.
[0010] The pants body 120 has a front body 122, a joining portion 123, and a back body 124. The joining portion 123 is a portion where the front body 122 and the back body 124 are joined by sewing together. The joining portion 123 is located in a portion corresponding to the wearer's crotch.
[0011] The front body 122 of the pants body 120 is a fabric that extends from the front lower portion 111 to the crotch area. The front body 122 has a pair of tucks 122t on either side of the horizontal center. The tucks 122t are formed by folding the outer fabric toward the center. The front body 122 may have multiple pairs of tucks on either side of the horizontal center.
[0012] The rear body 124 of the pants body 120 is a fabric that extends from the rear lower portion 112 to the crotch area. As shown in Fig. 2, the width of the rear body 124 is greater than the width of the front body 122 over the entire area from the waist belt 110 to the crotch area. The surface area of the rear body 124 is greater than the surface area of the front body 122.
[0013] The front lower portion 111 of the waist belt 110 is a first connecting portion where the front body 122 is connected to the waist belt 110. The front body 122 is sewn to the waist belt 110 at the front lower portion 111. The rear lower portion 112 of the waist belt 110 is a second connecting portion where the back body 124 is connected to the waist belt 110. The back body 124 is sewn to the waist belt 110 at the rear lower portion 112. The front lower portion 111 and the rear lower portion 112 are separated from each other. The waist belt 110 has a separation portion 113 between the front lower portion 111 and the rear lower portion 112 where the pants body 120 is not connected.
[0014] According to the fundoshi-type pants 100 described above, the surface area of the back body 124, which covers the buttocks that are wider than the lower abdomen, is made larger than that of the front body 122, and by providing a pair of tucks 122t in the front body 122, it is possible to provide more room from the lower abdomen to the crotch area. As a result, the fundoshi-type pants 100 can improve the wearing comfort.
[0015] The technology disclosed in this specification is not limited to the above-described embodiments, examples, and modifications, and can be realized in various configurations without departing from the spirit thereof. For example, among the technical features of the above-described embodiments, examples, and modifications, those corresponding to the technical features of each form described in the Summary of the Invention column can be appropriately replaced and combined to solve some or all of the above-described problems or achieve some or all of the above-described effects. Furthermore, technical features not described as essential in this specification can be appropriately deleted. [Explanation of symbols]
