(Embodiment)
A lower garment 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. The lower garment 1 is formed by connecting stretchable fabrics that do not require trimming. Each fabric forming the lower garment 1 does not fray even if the cut surface of the fabric is exposed, so end processing such as threading the cut surface or bag-sewing is unnecessary. Therefore, even if the cut surface of the fabric of the lower garment 1 comes into contact with the wearer's skin, the burden placed on the skin is small and a comfortable touch can be obtained.

In the embodiment of the present invention, the lower garment 1 is a boxer-type underwear for men, but it is not limited to this. For example, the lower garment 1 is not limited to boxer-type underwear, but may be other men's underwear such as briefs, trunks, suteteko, tights, spats, and leggings. In the embodiment of the present invention, the lower garment 1 has a length that covers the upper part of the thigh, but it may have a short type length that does not cover the thigh. Also, the lower garment 1 will be described assuming that the upper end is close to the waist, but the lower garment 1 may be of a so-called low-rise type with a low waist position. Any clothing may be used as long as it is made of stretchable fabric that does not require trimming, and has a front portion 5 that covers a male's private part (male genitalia).

In the embodiment of the present invention, the lower garment 1 includes a left front body part 2 that covers the left front part of the lower abdomen, a right front body part 3 that covers the right front part of the lower abdomen and is arranged closer to the skin than the left front body part 2, It has a back body part 4 covering the buttocks. The lower garment 1 is formed by connecting at least three fabrics of a left front body part 2, a right front body part 3 and a back body part 4. - 特許庁The left front body part 2, the right front body part 3, and the back body part 4 are made of materials such as bare smooth, bare jersey, bare milling, bare single bag, two-way raschel, two-way tricot, and double raschel.

In the embodiment of the present invention, the left front body part 2, the right front body part 3, and the back body part 4 are each formed of one sheet of fabric, but the present invention is not limited to this. For example, the left front body part 2, the right front body part 3, and the back body part 4 are each formed of a plurality of fabrics, such as dividing the back body part 4 into a left back body part and a right back body part and connecting them near the left and right center lines. May be.

The front part 5 is a part that covers a male's private part. The front part 5 is formed by stacking the left front body part 2 and the right front body part 3 . In the front part 5, the left front body part 2 and the right front body part 3 are connected by a left connection part 21 and a right connection part 31 above. The lower end of the right front body portion 3, the lower end of the left front body portion 2, and the lower end of the back body portion 4 are connected by a crotch connecting portion 42. As shown in FIG. As shown in FIG. 4, the lower ends of the left front body portion 2 and the right front body portion 3, which are stacked in the left-right direction, and the lower end of the back body portion 4 are sewn to each other with the front facing inward, thereby forming a crotch connection portion 42. is formed.

In the example shown in FIG. 4, the intersection of the right end 22 of the left front body part 2 and the crotch connection part 42 is positioned near the boundary between the trunk and the right leg. The intersection of the left end 32 of the right front body part 3 and the crotch connection part 42 is located near the boundary between the trunk and the left leg.

The right side of the right front body part 3 , the left side of the left front body part 2 , and the left and right side sides of the back body part 4 of the lower garment 1 are connected by a pair of left and right side connection parts 41 . The left front body part 2, the right front body part 3, and the back body part 4 are connected with an adhesive, but the present invention is not limited to this. For example, they may be connected by a method capable of generating tightening force by connecting the fabrics, such as sewing with a thread or an extraction process. In addition, in order to reduce the burden of adhesion, a sewn stop may be provided at an appropriate place of the portion to be connected by the adhesive.

The left front body part 2 and the back body part 4 are overlapped to form the left side connection part 41, and the right front body part 3 and the back body part 4 are overlapped to form the right side connection part 41. - 特許庁In the embodiment of the present invention, the left front body part 2 and the right front body part 3 are arranged closer to the skin than the back body part 4 is.

The side connection part 41 has a desired tightening force by overlapping the left front body part 2, the right front body part 3 and the back body part 4 and connecting them with an adhesive. Although the lower garment 1 is not provided with a rubber to prevent it from slipping down at the waist position, the waist of the lower garment 1 is prevented from slipping down due to the tightening force of the side connecting portions 41 .

As shown in FIGS. 1 to 3 and the like, the side connection portion 41 has an inverted triangular shape above the greater trochanter and a linear shape (rectangular shape) below the greater trochanter. The side ends of the left front body part 2 and the right front body part 3 (ends connected to the back body part 4) extend to the left and right center line sides, and while drawing a curve, pass near the greater trochanter and reach the left and right side ends. Almost vertically down the neighborhood. On the other hand, the armpit ends of the back body part 4 (connecting ends to the left front body part 2 and the right front body part 3) descend substantially vertically near the left and right sides. As a result, the side connecting portion 41 is formed in an inverted triangle shape above the greater trochanter in the vicinity of the left and right sides. Since the armpit connecting portions 41 can tighten the left and right armpits above the greater trochanter, the tightness at the waist position of the left and right ends can be reduced, and the contact with the skin and the comfort can be improved. Also, by tightening the left and right armpits, it is possible to improve the fitting feeling between the lower garment 1 and the skin on the left and right armpits.

In addition, since the side connection portions 41 are formed smaller in the lateral direction near the greater trochanter than in the vicinity of the waist, the tightening force of the side connection portions 41 has little effect on the greater trochanter. Therefore, even when the lower garment 1 is in close contact with the skin, it is difficult for the garment to slip off due to movement.

As shown in FIG. 3, the upper inverted triangular portion of the armpit connection portion 41 is arranged wider on the back side than on the front side, so that it can be stably arranged at a position corresponding to the pelvis. As a result, the tightening force of the inverted triangular portion can be effectively exerted, and the uncomfortable feeling of the wearer due to the tightening force can be reduced.

(front part)
Referring to FIGS. 5-7, reference is made to the front portion 5. FIG. 5(a) and 7(a) relate to the right front body part 3, and FIGS. 5(b) and 7(b) relate to the left front body part 2. FIG.

As shown in FIG. 5, in the front part 5, the left front body part 2 forms darts 23 extending upward from the crotch connection part 42 near the left-right center line, and the right front body part 3 forms a dart 23 near the left-right center line. A dart 33 is formed extending upward from the crotch connection 42 . With these darts, the front portion 5 can be three-dimensionally formed according to the shape of the local area.

In the front part 5 , the left front body part 2 and the right front body part 3 are connected above by an adhesive applied to the left connection part 21 and the right connection part 31 .

As shown in FIG. 5( a ), the right connecting portion 31 connects the upper portion of the left end 32 of the right front body portion 3 to the left front body portion 2 . The left end 32 of the right front body part 3 is formed on the left side of the local part by exposing the cut surface of the fabric. Between the right connecting portion 31 and the crotch connecting portion 42 of the left end 32 of the right front body portion 3 , it is formed so as to be separable from the left front body portion 2 .

As shown in FIG. 5B , the left connecting portion 21 connects the upper portion of the right end 22 of the left front body portion 2 to the right front body portion 3 . The right end 22 of the left front body part 2 is formed on the right side of the local part by exposing the cut surface of the fabric. Between the left connecting portion 21 and the crotch connecting portion 42 of the right end 22 of the left front body portion 2, it is formed so as to be separable.

An opening portion P21 is formed between the left connecting portion 21 and the crotch connecting portion 42, and similarly an opening portion P31 is formed between the right connecting portion 31 and the crotch connecting portion 42. As shown in FIG. Of the right end 22 of the left front body part 2, the opening part P21 between the left connection part 21 and the crotch connection part 42 is not connected to the right front body part 3, and of the left end 32 of the right front body part 3, the right connection part An opening portion P31 between 31 and the crotch connection portion 42 is not connected to the left front body portion 2 . A private part covered by the front part 5 can be taken in and out through the openings P21 and P31.

The tightening force obtained by stacking two fabrics in the front part 5 provides a natural fit. Also, at the openings P21 and P31, cut surfaces of the fabric are exposed, and edge processing such as seams is not formed. While the elongation of the fabric is generally restricted by the edge processing, the lower garment 1 according to the embodiment of the present invention is comfortable to wear without a feeling of oppression and unevenness caused by the edge processing. In addition, since the openings P21 and P31 are not edge-treated, there is an effect that the male genitalia (penis) can be easily put in and taken out.

In general, it is known that the wearer suffers from chronic residual urine after urination due to functional deterioration due to aging. A person suffering from such symptoms sometimes urinates with the lower garment 1 lowered to the knees in order to avoid the feeling of oppression caused by the end processing of the general lower garment. In order to drain more urine, the remaining urine in the urethra may be manually squeezed out from under the scrotum. According to the lower garment 1 according to the embodiment of the present invention, since there is no end treatment and the male genitalia are not pressed, the penis can be easily protruded from the openings P21 and P31 without lowering the lower garment 1 above the knees. Able to urinate. In addition, when the urine remaining in the urethra is manually squeezed out from under the scrotum, the end treatment does not tighten the penis even when the penis is taken out, so the burden on the penis is reduced and urination is facilitated. be able to.

In addition, the left front body part 2 and the right front body part 3 are formed to be separable between the left connection part 21 and the right connection part 31 . As shown in FIG. 6, between the connecting portion 21a of the left connecting portion 21 and the connecting portion 31a of the right connecting portion 31 in the left front body portion 2 P22, and the connecting portion 21b of the left connecting portion 21 in the right front body portion 3 , and the connection portion 31b of the right connection portion 31 are not connected. Between P22 and P32, there is no tightening force associated with the connection, and a material with a strong tightening force such as rubber is not disposed, so the material itself of the left front body portion 2 and the right front body portion 3 is relatively weak. It is placed against the wearer's skin with a tightening force.

As a result, the fabrics of the left front body part 2, the right front body part 3, and the back body part 4 are not tightened by a material with a strong tightening force such as rubber in the vicinity of the wearer's waist. , It stays on the skin, so it feels good on the skin and provides a comfortable wearing feeling. Furthermore, the tightening force of the side connection portions 41 prevents the bottom garment 1 from slipping down. Moreover, the portion where the interval P22 and the interval P32 are arranged is the abdomen, and there is no bone supporting the abdomen. Since the tightening force is weak in the interval P22 and the interval P32, the burden on the skin of the abdomen is small, which is preferable.

In general, the front body part of a men's undergarment may be affected by local weight, shaking, and the like, and the waist position may shift downward. In the front part 5 according to the embodiment of the present invention, the left front body part 2 and the right front body part 3 are connected only at the left connection part 21, the right connection part 31 and the crotch connection part 42, and the other parts are formed to be separable. can act independently. Therefore, even if the right front body part 3 arranged on the skin side is affected by local weight or shaking, the left front body part 2 arranged on the outside is less affected by it, so the waist position is stabilized. easy to deploy.

It is preferable that the left connecting portion 21 and the right connecting portion 31 are arranged such that the longitudinal direction thereof is the vertical direction. The left connecting part 21 and the right connecting part 31 are formed vertically from the upper ends of the left front body part 2 and the right front body part 3 so as to ensure the size of the opening for putting in and out the private parts. Further, the left connecting portion 21 and the right connecting portion 31 are formed thin in the left-right direction, so that the lower garment 1 is prevented from slipping down due to the tightening force of the side connecting portions 41 even if there is no tightening force. Therefore, it is preferable that the left connecting portion 21 and the right connecting portion 31 are formed to be short in the horizontal direction and long in the vertical direction.

In the embodiment of the present invention, dots of adhesive are discretely and evenly applied to the left connection portion 21 and the right connection portion 31, but the present invention is not limited to this. For example, an adhesive may be applied to one surface of each of the left connection portion 21 and the right connection portion 31 . Moreover, the left connection portion 21 and the right connection portion 31 may be formed by a set of a plurality of shapes instead of providing one rectangular connection portion, respectively, as in the embodiment of the present invention. For example, the left connection portion 21 and the right connection portion 31 may be formed by vertically arranging a plurality of rectangular or circular connection portions.

The distance of the left front body part 2 from the left connection part 21 to the crotch connection part 42 is formed shorter than the distance of the right front body part 3 . From the right connecting portion 31 to the crotch connecting portion, the distance of the right front body portion 3 is formed shorter than the distance of the left front body portion 2 .

For example, the patterns of the left front body part 2 and the right front body part 3 shown in FIG. 7 are shown. L in FIG. 7 is the left-right center line. A symbol with a "-" in a circle indicates a portion to be adhered. The reference numbers of the respective parts on the pattern paper in FIG.

In FIGS. 7A and 7B, there are two white lines with square terminals (P21ak and P21bk) and two white lines with round terminals (P31ak and P31bk). Two lines with the same terminal means that they overlap in the lower garment 1 . P21ak and P21bk overlap, and P31ak and P31bk overlap.

P21ak is a line connecting the lower end of the left connecting portion 21ak of the left front body portion 2k to the crotch connecting portion 42ak. P21bk is a line connecting the lower end of the left connecting portion 21bk in the right front body portion 3k to the crotch connecting portion 42bk. P21ak is shorter than P21bk.

P31ak is a line connecting the lower end of the right connecting portion 31ak of the left front body portion 2k to the crotch connecting portion 42ak. P31bk is a line connecting the lower end of the right connecting portion 31bk of the right front body portion 3k to the crotch connecting portion 42bk. P31bk is shorter than P31ak.

As described above, in the embodiment of the present invention, each end portion of the left front body portion 2 and the right front body portion 3 on the left and right center line side is shorter than the portions of the left front body portion 2 and the right front body portion 3 where the respective end portions overlap. By being formed, the lower garment 1 is stretched when worn. As a result, the ends of the left front body part 2 and the right front body part 3 on the left and right center line side press the left and right parts of a man's private parts to fit and support the private parts. In addition, since the fit accompanies the extension of the ends of the fabric, the pressure is weaker and the burden on the skin is lighter than in the case of fitting by finishing the ends.

In the embodiment of the present invention, the side connection part 41 is formed in the vicinity of the upper side in the longitudinal direction in the horizontal direction, and a plurality of connection bands having a tightening force due to the connection of the fabric are arranged at intervals in the vertical direction. is set. Stretching of the skin from the waist position to the position near the greater trochanter due to the movement of the upper body may be more noticeable in the vertical direction (wearer's height direction) than in the horizontal direction (wearer's width direction). Many things are known. Therefore, by arranging a plurality of connecting bands having tightening force at intervals in the vertical direction, the non-connecting bands that do not connect fabrics and do not have tightening force can be stretched according to the vertical elongation. can be done. As a result, the side connection portion 41 can be stretched in accordance with the stretch in the vertical direction while securing the tightening force in the left-right direction and preventing the side connection portion 41 from sliding down.

In this manner, the men's lower garment 1 according to the embodiment of the present invention can be formed by connecting stretchable fabrics that do not require termination.

(fabric characteristics)
The left front body part 2, the right front body part 3, and the back body part 4 have an elongation rate in the vertical direction (wearer's length direction) of about 130% to 190%, and an elongation rate in the left-right direction (wearer's width direction). However, a material of about 190% to 260% is preferable. The left front body part 2, the right front body part 3, and the back body part 4 are preferably made of a material having an elongation recovery force of about 20 cN to 60 cN in both the vertical direction and the lateral direction.

In an embodiment of the present invention, the elongation rate and elongation recovery force are measured by attaching a 160 mm x 25 mm test piece to a constant speed elongation type tensile tester with an upper grip of 25 mm, a lower grip of 35 mm and a grip interval of 100 mm. be. A plurality of test pieces are used, which are cut so that the warp and weft directions of the fabric are in the longitudinal direction (16 mm side).

The elongation rate was measured by attaching a test piece to a constant-speed elongation type tensile tester and applying a load of 14.7 N to the test piece in the lateral direction and the vertical direction. The elongation recovery force was measured by attaching the test piece to a constant-speed elongation type tensile tester, repeating the elongation recovery several times at a speed of about 300 mm / min, and the elongation force (cN) when elongating 30% and recovering to 30%. It is calculated by the average of the recovery force (cN) at the time.
