(Embodiment)
A lower garment 1 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. The lower garment 1 is formed by connecting stretchable fabrics that do not require cleaning up ends. Each of the fabrics forming the lower garment 1 does not fray even if the cut surface of the fabric is exposed, so there is no need for edge treatments such as threading the cut surface or bag stitching. Even when the cut surface of the fabric of the lower garment 1 comes into contact with the wearer's skin, there is less burden on the skin and a comfortable touch can be obtained.

In the embodiment of the present invention, a case will be described in which the lower garment 1 is a boxer type underwear for men, but the present invention is not limited to this. The lower garment 1 is, for example, not limited to boxer-type underwear, but may also be other men's underwear such as briefs, trunks, or shorts, or women's underwear, girdles, tights, spats, leggings, etc. It's okay. The lower garment 1 may be any garment that is made of stretchable fabric that does not require any cleaning, covers the waist, and requires a good fit against the skin, especially at the left and right sides of the waist.

The lower garment 1 includes a main body portion that covers the lower abdomen, and the main body portion is formed by a front body portion 2 and a back body portion 3. The front body part 2 and the back body part 3 are each formed of stretchable fabric that does not require any finishing. The front body part 2 and the back body part 3 can cover the lower abdomen by connecting at the left and right sides and at the crotch. For the front body part 2 and the back body part 3, materials such as bare smooth, bare jersey, bare milling, bare piece bag, two-way raschel, two-way tricot, double raschel, etc. are used.

In the embodiment of the present invention, the front body part 2 includes a right front body part 21 and a left front body part 22. By overlapping the right front body part 21 and the left front body part 22, a front part 23 that covers a man's private parts (male genitals) is formed. The right front body part 21 and the left front body part 22 are connected at a pair of left and right front body connection parts 24 provided above, and the lower part is not connected, thereby forming an opening in the front part 23 through which a man's private parts can be taken in and taken out. It's okay to be. The back body portion 3 is formed from a single piece of fabric.

The front body part 2 and the back body part 3 are formed as appropriate according to the functions required of each lower garment, such as men's, women's, and girdle lower garments. Therefore, the front body part 2 and the back body part 3 may each be formed from one piece of fabric, or may be formed from three or more pieces of fabric.

The lower garment 1 has overlapping parts 4 on the left and right sides where the fabric overlaps. The overlapping portions 4 are formed in a pair on the left and right. In the embodiment of the present invention, the overlapping part 4 is formed by overlapping the fabrics of the front body part 2 and the back body part 3. The overlapping part 4 connects the front body part 2 and the back body part 3 in an overlapping manner by bonding with an adhesive, and has a desired tightening force.

In the embodiment of the present invention, a case will be described in which the front body part 2 and the back body part 3 are connected by adhesive, but the present invention is not limited to this. For example, the connection may be made by a method that can generate a tightening force by connecting the fabrics, such as sewing with thread, thermocompression bonding, or punching.

In the embodiment of the present invention, a case will be described in which the overlapping portion 4 is formed by overlapping and connecting the front body portion 2 and the back body portion 3 at the left and right sides, but the present invention is not limited to this. In other embodiments, when the lower garment covering the lower abdomen is formed by switching fabrics other than the left and right armpits or by knitting them into a tube shape, one piece of fabric provided on the left and right armpits is covered with another cloth. The overlapping portion 4 may be formed by overlapping the cloths.

In the embodiment of the present invention, each of the fabrics forming the lower garment 1 does not need to be cleaned up and will not fray on the cut surface of the fabric. Each of the fabrics forming the lower garment 1 has elasticity, so it stretches to match the wearer's waist circumference and fits the wearer's skin. The upper end of the lower garment 1 is made of uncut fabric and has no ends, so that it feels good against the skin and is comfortable to wear. In addition, due to the structure of the overlapping portion 4 described later, the lower garment 1 has stretch stops formed on the left and right sides of the waist, so that the lower garment 1 does not slip down even when an elastic member with a high tightening force such as rubber is not provided at the waist. can be prevented.

(overlapping part)
The configuration of the overlapping portion 4 will be described with reference to FIGS. 4 and 5. Fig. 4 shows the right overlapping part 4 laid flat with the outer side of the lower garment 1 facing up (the side that does not contact the skin), and Fig. 5 shows the right overlapping part 4 with the lower garment 1 turned inside out. is placed flat with the skin side (the surface that contacts the skin) of the lower garment 1 facing up. The right side of FIG. 4 and the left side of FIG. 5 are the front of the wearer, and the left side of FIG. 4 and the right side of FIG. 5 are the front of the wearer.

As shown in FIGS. 4 and 5, the right front body part 21 is disposed on the skin side, and the back body part 3 is disposed on the outside of the right front body part 21. The upper end of the side end 3a of the back body part 3 is formed to extend forward, and the upper end of the side end 2a of the right front body part 21 is formed to extend backward. Here, the length by which the upper end of the side end 2a of the front body part 2 extends rearward is greater than the length by which the upper end of the side end 3a of the rear body part 3 extends forward. In other words, the side edge 3a of the rear body part 3 is formed to draw a smaller curve than the right front body part 21 from the upper end to a position near the greater trochanter, and to draw a straight line from the position near the greater trochanter to the lower end. On the other hand, the side edge 2a of the right front body part 21 is formed to draw a larger curve than the rear body part 3 from the upper end to a position near the greater trochanter, and to draw a straight line shape from the position near the greater trochanter to the lower end.

In the embodiment of the present invention, the overlapping part 4 is formed by overlapping two pieces of fabric, the front body part 2 and the back body part 3, but the invention is not limited thereto. For example, each side edge of the front body part 2 and the back body part 3 is formed into a straight line shape, and the side ends of the front body part 2 and the back body part 3 are connected with the necessary overlap to connect the fabrics, and an inverted triangular patch is attached to the front body part 2 and the back body part 3. An overlapping portion 4 may be formed overlapping the connecting portion. Alternatively, the front body part 2 and the back body part 3 may be formed of a single piece of cloth at the left and right sides without overlapping, and an inverted triangular patch cloth may be placed on top of the cloth to form the overlapping part 4. Moreover, although the case where the right front body part 21 is disposed on the skin side has been described, the back body part 3 may be disposed on the skin side.

As shown in FIG. 4 and the like, sewing stops 43 are provided at the front and rear ends of the upper end and the lower end of the overlapping portion 4. Since the portion where the sewing stopper 43 is provided is subject to stress and the adhesive is likely to peel off, the sewing stopper 43 reduces the burden and reinforces the adhesiveness.

Since the overlapping part 4 is bonded with an adhesive, it has lower elasticity than parts other than the overlapping part 4, has a higher tightening force, and is prevented from elongating. As a result, the overlapping portion 4 is difficult to stretch among the waist portions of the lower garment 1, and serves as a fulcrum for expansion and contraction of the waist portion. Since the overlapping portion 4 can suppress expansion and contraction compared to the case where the entire waist expands and contracts, it is possible to prevent the waist portion from slipping down.

As shown in FIGS. 1, 4, etc., the overlapping part 4 has a waist-armpit connection part 41 and a hem-armpit connection part 42. The waist side connection portion 41 and the hem side connection portion 42 are formed symmetrically. In the vicinity of the position corresponding to the greater trochanter, the waist-armpit connecting part 41 and the hem-armpit connecting part 42 connect to form an overlapping part 4.

(Waist side connection part)
The waist-armpit connecting part 41 is provided above the overlapping part 4 and connects the front body part 2 and the back body part 3 near the upper side of the lower garment 1. The waist-armpit connection portion 41 has a tightening force due to the connection of the fabrics of the front body portion 2 and the back body portion 3.

Specifically, the waist-armpit connecting portion 41 is formed in an inverted triangular shape with an upper end long in the left-right direction (circumferential direction of the waist) and a lower end narrow, from the waist position at the upper end of the lower garment 1 to a position near the greater trochanter. . In the embodiment of the present invention, in the case of the lower garment 1 of medium size (waist 76 cm to 84 cm), the entire circumference of the upper end of the lower garment 1 is 52.3 cm when laid flat. In this case, the length of the upper end of the right waist-armpit connecting part 41 in the left-right direction is about 5 cm to 15 cm, and the length of the lower end is about 0.5 cm to 2 cm. The length of the upper end of the waist-armpit connection part 41 is adjusted as appropriate depending on the characteristics of the fabric used for the lower garment 1, the characteristics of the adhesive, etc.

The upper side of the waist-armpit connecting part 41 is formed longer in the left-right direction than the lower side. The waist-armpit connecting portion 41 is formed so that its length in the left-right direction gradually decreases from the upper side to the lower side.

As a result, the waist-armpit connecting portion 41 exerts a tightening force on a surface that extends in the vertical and horizontal directions. For example, if a tightening force to prevent slippage is achieved only at the left and right waist positions (upper ends), a large tightening force is required at the waist position, which may cause discomfort to the wearer's skin. In contrast, the waist-armpit connecting portion 41 according to the embodiment of the present invention generates a tightening force from the waist position to a position near the greater trochanter. Since the waist-armpit connecting portion 41 can tighten the left and right armpits, the tightness at the waist position at the left and right ends can be reduced, and the skin contact and comfort can be improved. Furthermore, by tightening the left and right armpits with the surfaces, it is possible to improve the fit between the lower garment 1 and the skin at the left and right armpits.

Further, the length of the waist-armpit connecting part 41 in the left-right direction is long in the upper part and gradually becomes shorter in the lower part, so that a strong tightening force can be generated at the upper end. Thereby, the power to pull up the lower garment 1 from above the waist-armpit connecting portion 41 becomes stronger, and it is possible to effectively prevent the lower garment from slipping down.

Since the waist-armpit connecting portion 41 is formed smaller in the left-right direction near the greater trochanter than near the waist, the tightening force of the waist-armpit connecting portion 41 has less influence on the greater trochanter. Therefore, even if the lower garment 1 fits the skin, it is unlikely to slip off due to movement.

In the embodiment of the present invention, the length of the waist-armpit connecting portion 41 in the left-right direction is long in the upper direction and gradually shortened in the lower direction, but the length is not limited to this. For example, the amount of adhesive per unit area near the top side may be increased to create a high tightening force, and the amount of adhesive may be gradually decreased toward the bottom to create a lower tightening force.

The rear end 5b of the waist-armpit connection part 41 is formed into a curved shape with a larger curvature than the front end 5a. The rear end 5b of the waist-armpit connection part 41 draws a large curve from the waist position to a position near the greater trochanter, while the front end 5a draws a smaller curve than the rear end 5b. As a result, the area where the overlapped portion 4 is observed in the rear view shown in FIG. 2 is larger than the area where the overlapped portion 4 is observed in the front view shown in FIG. By arranging the lumbar armpit connecting portion 41 of the overlapping portion 4 wider on the dorsal side than on the front side, the lumbar armpit connecting portion 41 can be stably disposed at a position corresponding to the pelvis. Thereby, the tightening force of the waist-armpit connecting portions 41 can be effectively exerted, and furthermore, the discomfort felt by the wearer due to the tightening force of the waist-armpit connecting portions 41 can be reduced.

(Adhesion of waist and armpit joints)
Referring to FIG. 6, the bonded portion of the waist-armpit connection portion 41 according to the embodiment of the present invention will be described. FIG. 6 is a cut-out diagram of the overlapping portion 4 of the paper pattern. In the diagram shown in FIG. 6, the adhesive is applied to the "o" portion of the overlapping portion 4. The adhesive has a dot shape and is applied discretely and uniformly.

In the waist-armpit connection part 41, a plurality of connection bands 44 whose longitudinal direction is formed in the left-right direction (circumferential direction) are arranged at intervals in the vertical direction. The connection band 44 is a part that has a tightening force due to the connection of the fabrics of the front body part 2 and the back body part 3. The connecting band 44 includes a portion where the adhesive for bonding the front body portion 2 and the back body portion 3 is applied, and a portion around the same, and is a portion that exerts a predetermined tightening force.

As shown in FIG. 6, in the waist-armpit connection portion 41, connection bands 44 coated with adhesive and having a tightening force and non-connection bands 45 not coated with adhesive are arranged alternately in the vertical direction. This makes it possible for the waist-armpit connecting portion 41 to achieve both horizontal tightening force (circumferential direction) and vertical elongation.

In the case where the adhesive is applied to the entire surface of the waist-armpit connection portion 41 without disposing the non-connection band 45, the waist-armpit portion is strongly tightened. As the upper body moves, the skin from the waist to the vicinity of the greater trochanter expands and contracts.If the tightening force at the waist and armpits is strong, the skin cannot follow the expansion and contraction of the skin, making it difficult to move or wearing clothes. Cracks may occur. The stretching of the skin from the waist to the vicinity of the greater trochanter as the upper body moves may be more pronounced in the vertical direction (height direction of the wearer) than in the left-right direction (width direction of the wearer). many.

Therefore, in the embodiment of the present invention, by alternately arranging the connecting bands 44 and non-connecting bands 45 in the vertical direction, the waist-armpit connecting portion 41 can accommodate the expansion in the vertical direction. Even when the skin from the waist position to the vicinity of the greater trochanter expands and contracts as the upper body moves, the waist-armpit connecting part 41 can follow the expansion and contraction of the skin. As a result, the waist-armpit connecting portion 41 can realize ease of movement and resistance to slippage.

In the embodiment of the present invention, the vertical length of the connection band 44 and the non-connection band 45 is approximately 8:5, but it is preferably about 7:3 to 5:8 depending on the characteristics of the fabric or adhesive. The length of the non-connecting band 45 in the vertical direction is not affected by restrictions on the elongation of the non-connecting band 45, so long as it has a length that can ensure the vertical elongation required for the waist-armpit connecting portion 41. The lengths of the connecting band 44 and the non-connecting band 45 are appropriately set according to the characteristics of the fabric used for the front body part 2 and the back body part 3, the characteristics of the adhesive, and the like.

The connection band 44 and non-connection band 45 of the waist-armpit connection portion 41 will be described in detail with reference to FIGS. 7 and 8. FIG. 7 is an enlarged view of region R shown in FIG. In FIGS. 7 and 8, the degree of elongation of the dough is shown in four levels: large, large minus, medium, and small. The growth decreases in the order of large, large minus, medium, and small. 7(a) shows the respective extensions of the applied part 44a to which adhesive is applied and the non-applied part 44b to which adhesive is not applied in the connection band 44, and FIG. 7(b) shows the extension of the applied part 44a and the unapplied part 44b. It shows the elongation of the connection band 44 in which the portion 44b and the portion 44b coexist.

As shown in FIG. 7(a), the connection band 44 has an applied part 44a to which an adhesive is applied and a non-applied part 44b to which no adhesive is applied. The application portion 44a has a small elongation per unit area due to the influence of the adhesive. On the other hand, in the non-applied portion 44b, although no adhesive is applied, the elongation is restricted by the applied portion 44a, and the elongation per unit area becomes significantly negative. As a result of the coexistence of coated portions 44a and non-coated portions 44b, the connection band 44 has a medium elongation per unit area, as shown in FIG. 7(b). Since the adhesive is applied uniformly, the elongation in the connecting band 44 is the same in the horizontal and vertical directions.

Since no adhesive is applied to the non-connecting band 45, the non-connecting band 45 alone has a large elongation per unit area in the vertical and horizontal directions. However, the connection band 44 is adjacent to the non-connection band 45 in the vertical direction, and in the main part of the waist-armpit connection part 41, the left-right direction is the longitudinal direction of both the connection band 44 and the non-connection band 45. Therefore, the non-connecting band 45 becomes difficult to stretch in the left-right direction due to the restriction of the tightening force of the connecting band 44, and its elongation per unit area becomes significantly negative.

As a result, as shown in FIG. 8, the waist-armpit connecting portion 41 repeatedly exhibits moderate and large negative elongation per unit area in the left-right direction. In addition, the waist-armpit connecting portion 41 alternates between medium and large elongation per unit area in the vertical direction. Therefore, the waist-armpit connecting portion 41 is formed to be difficult to stretch in the left-right direction and easy to stretch in the up-down direction.

Further, since the waist-armpit connecting portion 41 is formed to be long in the left-right direction near the upper side, it is possible to form the waist-armpit connecting portion 41 so that it is difficult to stretch in the left-right direction (the tightening force is large) near the upper side. can. In addition, as the waist-armpit connecting portion 41 approaches the lower side, the length in the left-right direction becomes shorter, so the difficulty in stretching is gradually reduced in the left-right direction, and the shape is formed so that it gradually becomes easier to stretch (lower tightening force). be done.

In this way, the waist-armpit connecting portion 41 can be formed so that it is difficult to stretch in the vicinity of the upper side in the left-right direction, becomes gradually easier to stretch as it approaches the bottom, and is easily stretchable in the up-down direction. Thereby, the waist-armpit connecting portion 41 can achieve both horizontal tightening force and vertical extension, form a stretch stop at the left and right armpits, and follow the expansion and contraction of the skin. Furthermore, by forming the lower garment 1 so that it does not stretch easily near the upper side, it is possible to efficiently prevent the lower garment 1 from slipping down.

Note that the waist-armpit connecting portion 41 according to the embodiment of the present invention has the following characteristics: the size of the waist-armpit connecting portion 41, the size of the connecting band 44 and the non-connecting band 45, and the size of the applied portion 44a and non-applicable portion 44b of the connecting band 44. It is specified by size etc. By appropriately adjusting these, desired tightening force and elongation can be achieved in the vertical and horizontal directions.

(Hem side connection part)
The hem side connecting portion 42 is provided below the overlapping portion 4. The hem side connecting portion 42 connects the front body portion 2 and the back body portion 3 near the lower side of the overlapping portion 4. The hem side connection portion 42 has a tightening force due to the connection of the respective fabrics of the front body portion 2 and the back body portion 3.

At the hem side connection part 42, the front body part 2 and the back body part 3 are connected in a vertically elongated rectangular shape from a position near the greater trochanter to the lower end of the lower garment 1. The hem side connecting portion 42 is formed in a linear shape to fit the hem to the skin and prevent the hem from riding up. In the embodiment of the present invention, in the case of M size (waist 76 cm to 84 cm) lower garment 1, when laid flat, the length in the left-right direction of the lower end of the right hem side connecting portion 42 is 0.5 It is about millimeter to 2 centimeters. The length of the hem side connecting portion 42 in the left and right direction is adjusted as appropriate depending on the characteristics of the fabric used for the lower garment 1, the characteristics of the adhesive, etc.

The hem side connection part 42 is a part where the adhesive for bonding the front body part 2 and the back body part 3 is applied and a part around it, and is a part that exerts a predetermined tightening force. As shown in FIG. 6, the hem side connecting portion 42 is coated with adhesive evenly in the vertical and horizontal directions, and is continuously connected. As a result, the hem side connecting portion 42 is arranged to fit the skin in the vertical direction, and can prevent the hem from sliding up. Further, since the hem side connecting portion 42 is disposed below the greater trochanter, the skin expands and contracts less as the wearer moves than above the greater trochanter. Therefore, even if there is no vertical spacing like the waist-armpit connecting portions 41, it is difficult to move and the wearer is less prone to misalignment.

(test)
The results of a comparative test on the overlapping portion 4 of the present invention are shown. In the comparison test, a tester wears the lower garment 1 according to the embodiment of the present invention and a comparison lower garment to be compared, and the questionnaires obtained from the tester are compared. As shown in FIG. 9(a), the first comparative lower garment is a lower garment in which the sides of the front body part and the back body part are connected in a straight line, and the side parts of the front body part and the back body part are connected in a straight line. The length of the portion in the left-right direction is 0.8 cm. The second comparative lower garment is a lower garment in which the sides of the front body and back body are connected in an inverted triangular shape, as shown in FIG. 9(b). The connecting portion has the same shape as the overlapping portion 4 according to the embodiment of the present invention, except that adhesive is applied to the entire surface of the connecting portion.

10 to 12 show side views of a wearer wearing the lower garment 1, the first comparative lower garment, and the second comparative lower garment according to the embodiment of the present invention. The left figures in Figures 10 to 12 show the wearer wearing each lower garment and getting used to it (before exercise), and the right figures show the wearer wearing each lower garment and getting used to it, while the wearer performs prescribed lower body exercises. This is the state after exercise (after exercise). The predetermined lower body exercise is bending/stretching 3 times and stepping 10 times.

When wearing the lower garment 1 according to the embodiment of the present invention, as shown in FIG. 10, the upper end position of the armpit is on L1 both before and after exercise, and the upper end position of the armpit remains unchanged. When wearing the first comparative lower garment, as shown in FIG. 11, the upper armpit position after exercise is 1.5 cm lower than the armpit upper end position L2 before exercise; It was confirmed that it was sliding downwards. When wearing the second comparative lower garment, as shown in FIG. 12, the upper armpit position after exercise is 1.0 cm lower than the armpit upper end position L3 before exercise; It was confirmed that it was sliding downwards.

Compared to the first comparative lower garment and the second comparative lower garment, the lower garment 1 according to the embodiment of the present invention does not shift at the upper end of the armpit side even when the lower body exercises, and fits the wearer better. I understand that.

In this way, the lower garment 1 according to the embodiment of the present invention can fit the wearer and prevent it from slipping down.

(Fabric characteristics)
The front body part 2 and the back body part 3 have an elongation rate in the vertical direction (wearer's length direction) of about 130% to 190%, and a horizontal direction (wearer's width direction) elongation rate of about 190% to 190%. A material of about 260% is preferable. The front body part 2 and the back body part 3 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 vertical 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 extension type tensile tester with an upper grip of 25 mm, a lower grip of 35 mm, and a grip interval of 100 mm. Ru. A plurality of test pieces are used, each of which is 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 the test piece to a constant speed extension type tensile testing machine and applying a load of 14.7 N to the test piece in the left-right direction and the up-down direction, respectively. The elongation recovery force was determined by attaching the test piece to a constant-speed elongation type tensile testing machine and repeating elongation recovery multiple times at a speed of about 300 mm/min, and calculating the elongation force (cN) when the test piece was elongated by 30% and the elongation force (cN) when the test piece recovered to 30%. Calculated by the average recovery force (cN) at the time of recovery.

(Modified example)
A lower garment 1a according to a modified example will be described with reference to FIGS. 13 and 14. The lower garment 1a has a lower waist position than the lower garment 1 according to the embodiment of the present invention, and is a so-called low-rise type men's underwear. Similarly to the lower garment 1 according to the embodiment, the lower garment 1a according to the modification also has overlapping portions 4a on the left and right sides, and the overlapping portions 4a have a waist armpit connecting portion 41a and a hem armpit connecting portion 42a.

In the modified example, as in the embodiment, the size of the overlapping part 4a, the size of the connecting band and non-connecting band in the overlapping part 4a, and the size of the coated part and non-coated part in the connecting part are adjusted as appropriate. I can do it. Thereby, the overlapping portion 4a can achieve desired tightening force and elongation in the vertical and horizontal directions.
