Description

[Technical Field]

[0001] The present invention relates to boxer-type briefs for men. [Background technology]

[0002] Conventionally, there are pants that are made by forming a front and back body from a tubular body fabric, forming a concave cutout in the lower central part of each of the front and back bodies, and sewing diamond-shaped crotch gussets (gussets) to the front and back cutouts (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 1-10003 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned conventional pants have a problem in that when worn by a wearer, the seam between the gusset (or crotch cloth) and the front body (front joint) is located at the front and rides up significantly on the penis or scrotum, making them uncomfortable to wear. One issue facing boxer shorts with a main body made of a tubular knit fabric is how to improve their comfort. In this specification, the penis and scrotum are collectively referred to as the "male part."

[0005] The present invention aims to provide men's boxer shorts with a main body made of a tubular knitted fabric, which reduce the amount of riding up on the men's part by positioning the front joining part of the crotch cloth towards the rear when worn, thereby improving the wearing comfort. [Means for solving the problem]

[0006] [1] One aspect of the present invention provides men's pants comprising a main body having a crotch cloth attachment section formed by cutting the front and back lower sections of a stretchy tubular knit fabric, and a crotch cloth section having front and rear edge edges joined to the crotch cloth attachment section of the main body, with a low-stretch section in at least the center lengthwise of the crotch cloth section having a lengthwise stretchability lower than that of the main body.

[0007] These men's pants are boxer shorts in which a crotch cloth attachment portion is formed on a stretchable tubular knit fabric, and the crotch cloth portion is attached to the crotch cloth attachment portion. These men's pants have a low-elasticity portion provided in at least the center of the crotch cloth portion in the length direction, which prevents the front joint portion from moving upward (slipping) when worn. If the crotch cloth portion is made of a fabric with good stretchability (e.g., one that stretches as easily as the main body portion), these fabrics will stretch almost uniformly over the entire length in the length direction. Therefore, the front joint portion of the crotch cloth portion is more likely to move forward and upward. Compared to this configuration, the front joint portion is positioned closer to the rear, stabilizing its position. Therefore, the amount by which the front joint portion rides up onto the men's part is reduced. As a result, the wearing comfort of boxer shorts with a main body portion made of a tubular knit fabric can be improved.

[0008] [2] In the men's pants described in [1] above, the low-elasticity portion may be provided so as to reach the front and rear edges of the crotch portion. With this configuration, the crotch portion has low elasticity throughout its entire length (front-to-back direction), and the position of the front joint portion can be reliably controlled (positioned stably downward).

[0009] [3] In the men's pants described in [1] or [2] above, the left and right side edges of the low-elasticity portion may be recessed toward the center of the body. This configuration prevents the left and right ends of the crotch cloth portion from constricting the wearer's thighs and allows them to easily conform to the wearer's body. As a result, the wearing comfort is further improved.

[0010] [4] In any one of the men's pants described in [1] to [3] above, the length of the crotch portion in the length direction when worn may be 15% to 19% of the total length in the length direction from the front center point of the waist of the men's pants, through the crotch, to the back center point of the waist. With this configuration, regardless of the degree of stretchability, the crotch portion covers only a limited range in the front and back, including the lowest point of the crotch. [Effects of the Invention]

[0011] According to the present invention, in boxer shorts having a main body made of a tubular knitted fabric, the front joining portion of the crotch cloth portion is positioned toward the rear when worn, thereby reducing the amount of riding up on the men's portion, and as a result, improving wearing comfort.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicated description will be omitted.

[0014] First, the basic configuration of men's pants 1 according to one embodiment will be described with reference to Figures 1 and 2. As shown in Figures 1 and 2, men's pants 1 comprise a main body portion 2 made from a stretchy tubular knit fabric, and a crotch cloth portion 20 connected to a crotch cloth attachment portion 9 of the main body portion 2. Men's pants 1 are boxer-type pants (boxer shorts). The main body portion 2 comprises a front portion 3, a back portion 4, and a waist portion 6 provided at the upper ends of the front portion 3 and the back portion 4.

[0015] The main body portion 2 is made of a stretchable material containing, for example, polyurethane yarn. The main body portion 2 is formed by circular knitting. Because the main body portion 2 is made of a continuous knitted fabric in the circumferential direction, there is no line (join line) such as a seam line between the front portion 3 and the back portion 4. The waist portion 6 is a band-like portion extending in the circumferential direction. The waist portion 6 and the front portion 3 and the back portion 4 may be formed in a single knitting process, or after the front portion 3 and the back portion 4 are knitted, the separately produced waist portion 6 may be joined to the upper ends of the front portion 3 and the back portion 4 by sewing or the like.

[0016] The front and rear U-shaped crotch cloth attachment portions 9 (see FIG. 2) of the main body portion 2 are formed by cutting the lower central portion of the front portion 3 (lower front portion) and the lower central portion of the back portion 4 (lower rear portion) of the tubular knit fabric into a U-shape. A front edge 23 of the crotch cloth portion 20 is joined to the front crotch cloth attachment portion 9, and a rear edge 24 of the crotch cloth portion 20 is joined to the rear crotch cloth attachment portion 9. The lengths of the pair of long sides of the roughly rectangular crotch cloth portion 20, i.e., the front edge 23 and the rear edge 24, are equal to the lengths of the front and rear crotch cloth attachment portions 9, 9 (i.e., the length along the U). The left and right side edges 25, 25 of the crotch cloth portion 20 are connected to the left and right front lower ends 3c and rear lower ends 4c (see FIG. 2) that remain after the lower central portion of the front portion 3 and the lower central portion of the back portion 4 are removed, respectively, to form left and right leg openings 10, 10. In the following description, men's pants 1 will be simply referred to as "pants 1."

[0017] The crotch cloth portion 20 is, for example, sewn to the crotch cloth attachment portion 9 of the main body portion 2. Note that if possible in consideration of the stretchability of the main body portion 2 and the crotch cloth portion 20, the crotch cloth portion 20 may be joined by means other than sewing (for example, by adhesion, etc.). The crotch cloth portion 20 may also be called a crotch portion.

[0018] A U-shaped structure modified portion 7, which has reduced stretchability due to a change in knitting structure, is formed in the front portion 3 of the main body portion 2. The area surrounded by the structure modified portion 7 serves as a cover portion 8 that covers the wearer's male part when the pants 1 are worn. From another perspective, the structure modified portion 7 and the cover portion 8 form a storage portion that stores the male part.

[0019] A "length direction" is defined for the pants 1. The length direction D is roughly equivalent to the up-down direction in the front and back regions 3 and 4, but in the case of the crotch cloth portion 20 that provides the crotch B, it means a U-shaped direction spanning the front and back regions 3 and 4. When the crotch cloth portion 20 is laid flat as shown in Figure 3, the length direction D coincides with the front-to-back direction across the crotch cloth portion 20.

[0020] The length L (see FIG. 3) of the crotch cloth portion 20 in the length direction D when worn is, for example, 15% to 19% of the total length of the pants 1 in the length direction D, which extends from the front center point Pa of the waist portion 6, through the crotch B, and to the back center point Pb of the waist portion 6. The stretchable material used for the crotch cloth portion 20 may be, for example, the same material as the stretchable material for the main body portion 2 described above.

[0021] 2 and 3, at least the central portion 21 in the length direction D of the crotch cloth portion 20 is provided with a low-elasticity portion 30 whose elasticity in the length direction D is lower than that of the main portion 2 in the length direction D. The low-elasticity portion 30 is knitted in a different way to achieve a structure that is less stretchable than the main portion 2. The knitting structure of the low-elasticity portion 30 may be, for example, rib knitting.

[0022] The extensibility in the length direction D of the main body portion 2 is, for example, 200% or more and 300% or less. The extensibility in the length direction D of the low stretch portion 30 is, for example, 120% or more and 180% or less. By appropriately setting the extensibility of the main body portion 2 and the low stretch portion 30 of the crotch cloth portion 20 within the above ranges, it is possible to obtain the advantage of being able to easily accommodate a variety of sizes. Note that the stretchability in the length direction D of portions of the crotch cloth portion 20 other than the low stretch portion 30, such as the general portions 26 located on the left and right sides of the low stretch portion 30, may be approximately the same as the stretchability in the length direction D of the main body portion 2.

[0023] The low stretch portion 30 is provided so as to reach the front edge 23 and the rear edge 24 of the crotch cloth portion 20. In other words, the front edge 31 of the low stretch portion 30 is located on the front edge 23 of the crotch cloth portion 20, and the rear edge 32 of the low stretch portion 30 is located on the rear edge 24 of the crotch cloth portion 20. In other words, the low stretch portion 30 is formed over the entire area of ​​the crotch cloth portion 20 in the length direction D.

[0024] 2 and 3, in the state where the crotch cloth portion 20 is laid flat, the left and right side edges 33 (both side edges) of the low-elasticity portion 30 are spaced apart from the left and right side edge 25 of the crotch cloth portion 20 and are located closer to the center of the body than the left and right side edge 25. In the state where the pants 1 are laid flat as shown in FIG. 1, the left and right side edges 33 (both side edges) of the low-elasticity portion 30 are located at a higher position than the left and right leg opening portions 10.

[0025] 2 and 3, the left and right side edges 33 (both side edges) of the low-elasticity portion 30 are recessed toward the center of the body, i.e., toward the central portion 21. For example, the left and right side edges are recessed so as to form a substantially triangular shape (a valley formed by two curved lines (arcuate lines)).

[0026] In the pants 1, the crotch cloth portion 20 is provided with a low-elasticity portion 30 made of a fabric with a different stretchability (elasticity) than the main body portion, thereby improving comfort (wearability) when worn. More specifically, as shown in FIGS. 1 and 5, when the pants 1 are worn, the amount by which the front joint portion 20F, which is the front edge 23 of the crotch cloth portion 20, rides up onto the male part (particularly the scrotum) is reduced. When the pants 1 are worn, the front joint portion 20F of the crotch cloth portion 20 is located at the rear (underside) of the wearer's scrotum or the perineum. In other words, the front joint portion 20F is located on the underside of the male part (although visibility varies slightly depending on the wearer) and tends to be invisible or difficult to see from the front. The "perineum" refers to the area posterior to the scrotum, which is elevated by wearing boxer shorts. When the pants 1 are worn, the front joint portion 20F of the crotch cloth portion 20 is not exposed in front of the bulge A (see FIG. 5) formed by the male part inside the cover portion 8, and is located at the height of the lower end Ax of the bulge. The front joint portion 20F of the crotch cloth portion 20 is located near the underside of the elevated scrotum or in front of the wearer's perineum.

[0027] The pants 1 of this embodiment are boxer shorts in which a crotch cloth attachment portion 9 is formed on a stretchable tubular knit fabric, and a crotch cloth portion 20 is attached to the crotch cloth attachment portion 9. According to these pants 1, a low-elasticity portion 30 provided in at least a central portion 21 of the crotch cloth portion 20 in the length direction D prevents the front joint portion 20F from moving upward (shifting) when worn. If the crotch cloth portion 20 is made of a fabric with good stretchability (e.g., stretching to the same extent as the main body portion), this fabric will stretch almost uniformly over the entire length in the length direction D from the front center point Pa of the waist portion 6 through the crotch B to the rear center point Pb of the waist portion 6. For example, in pants 100 according to a conventional example (comparative example) shown in FIG. 6, the front joint portion 120F, which is the front edge 123 of the crotch cloth portion 120, is prone to moving forward and upward. As a result, it is located on the front of the man's penis and is visible from the front. In other words, the front joint portion 120F is positioned higher than the lower end Ax of the bulge portion, and is positioned in front of the wearer's male part, riding significantly onto the penis or scrotum. According to the pants 1 of this embodiment shown in FIG. 5, the low-elasticity portion 30 is provided in the crotch cloth portion 20, and the proportion of the crotch cloth portion 20 in the overall length in the length direction D from the front center point Pa of the waist portion 6 through the crotch B to the rear center point Pb of the waist portion 6 is reduced. That is, the front joint portion 20F is positioned further rearward (lower), and the rear joint portion 20R is positioned further forward (lower). The crotch cloth portion 20 having the low-elasticity portion 30 positions the front joint portion 20F toward the rear (pulls in) and the rear joint portion 20R toward the front (pulls in). The position of the front joint portion 20F is stable. Therefore, the amount of riding of the front joint portion 20F onto the male part is reduced. As a result, the boxer shorts having a main body portion 2 made of a tubular knit fabric are comfortable to wear.

[0028] Furthermore, by shifting the position of the front joint portion 20F rearward, the cover portion 8 envelops the male part more widely, increasing comfort and stability. Furthermore, the low-elasticity portion 30 and the waist portion 6 act as fulcrums for stability, increasing the force pressing the main body portion 2 between them against the skin. Conventionally, with boxer-type shorts using tubular knitted fabrics, the main body portion is prone to lifting in the area corresponding to the groin, but the above-mentioned pressing force against the skin reduces this lifting of the main body portion 2, improving fit.

[0029] The low-elasticity portion 30 is provided so as to reach the front edge 23 and the rear edge 24 of the crotch cloth portion 20. As a result, the crotch cloth portion 20 has low elasticity over the entire length direction D (front-to-back direction), and the front joint portion 20F is stably positioned downward.

[0030] The left and right side edges 33 of the low-elasticity portion 30 are recessed toward the center of the body. This prevents the left and right ends of the crotch cloth portion 20 (near the general portion 26) from constricting the wearer's thighs and allows the garment to easily conform to the wearer's body. As a result, the wearing comfort is further improved. In particular, the above-mentioned effects are remarkable when each side edge 33 of the low-elasticity portion 30 includes one or more arc-shaped lines.

[0031] The length of the crotch cloth portion 20 in the length direction D when worn is 15% to 19% of the entire length in the length direction D from the front center point Pa of the waist portion 6 of the pants 1, through the crotch B, to the back center point Pb of the waist portion 6. As a result, no matter how low the stretchability, the crotch cloth portion 20 covers only a limited range in the front and back including the lowest point of the crotch B (the height of the lower end Ax of the bulge portion).

[0032] Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. For example, as in the crotch cloth portion 20A shown in FIG. 4(a), the left and right side edges 33A (both side edges) of the low-elasticity portion 30A may be valley-shaped, formed by two straight lines, and recessed toward the center of the body, i.e., toward the central portion 21. As in the crotch cloth portion 20B shown in FIG. 4(b), the left and right side edges 33B (both side edges) of the low-elasticity portion 30B may be arc-shaped, recessed toward the center of the body, i.e., toward the central portion 21. Furthermore, as in the crotch cloth portion 20C shown in FIG. 4(c), the low-elasticity portion 30C may include an arc-shaped side edge 33C similar to the left and right side edges 33B, but may not reach the front edge 23 or the back edge 24 of the crotch cloth portion 20C, and may extend only partially in the length direction D, including the central portion 21. The shape consisting of two arcuate lines in the above embodiment (see Figures 2 and 3) or the shape consisting of two straight lines shown in Figure 4(a) may be combined with a form in which each low-elasticity portion does not reach the front edge 23 and the rear edge 24 and extends only part of the length direction D.

[0033] The length L (see Figure 3) of the crotch cloth portion 20 in the length direction D when worn may be less than 16% or more than 19% of the total length of the pants 1 in the length direction D, which extends from the front center point Pa of the waist portion 6, through the crotch B, and to the back center point Pb of the waist portion 6.
