Description

  The present invention relates to underwear such as shorts, briefs, and girdles. In particular, the present invention is made of a free-cut cloth that does not require edge trimming, and prevents misalignment of the underwear when worn.

  Conventionally, underwear such as shorts is folded back at the edge of the waist-side wear mouth and foot-feeding foot mouth to form a tubular part, and a rubber cord is inserted through the tubular part, or rubber tape is sewn. The position shift during wearing is prevented by giving stretchability.

  In this way, double stitching with folded edges and sewing with rubber tape take time and effort to sew, and since that part becomes a convex part and bites into the skin and presses it recently, There has been proposed an underwear for a free-cut fabric that has been cut off with unused edges cut (for example, Patent Document 1).

  However, the shorts of the cut free cut fabric that does not need to clean the waistline and legs can be worn due to the shrinkage of the fabric itself, but the tightening force is extremely weak compared to rubber, making the body When moved, the position of the shorts shifted, causing discomfort when worn.

  Therefore, as shown in FIG. 22, as shown in FIG. 22, as shown in FIG. 22, the upper end edge of the shorts around the waist of the shorts is removed without removing the edges of the waist and legs. X1 and X2 are the left and right outer end points, and X3 and X4 are the outer end points of the left and right leg edges that are the maximum width, and the side lines connecting X1 and X3 and X2 and X4 are inclined lines that are close to each other. The inclined line has an inclination angle of 65 to 80 degrees with respect to the horizontal line S connecting the outer end points X3 and X4, and with respect to the dimension Y1 from the front center point X5 of the upper end edge to the lowermost end of the crotch part, The dimension Y2 from the front center point to the horizontal line S is Y2 / Y1 being 0.7 to 0.9, and the upper part of the shorts is made extremely long and the waistline part is extremely narrowed with respect to the hip part. It is recommended to prevent sliding down. Is (e.g., see Patent Document 2).

  In addition, there are various proposals such as shorts (Patent Document 3) in which both side edges of the front body and the back body are connected to each other at the back of the lumbar side, and men's underwear (Patent Document 4) attached to the front body by adhesive bonding. (Patent Documents 5 and 6 are other examples).

Registered Utility Model No. 3136098 JP 2012-193487 A Registered Utility Model No. 3003595 JP 2014-0845539 A Japanese Patent Laying-Open No. 2005-320642 JP 2008-150749 A

  However, the undergarments in Patent Documents 1 and 2 above are affected by the movement of the body such as crossing legs because the joint between the front body and the back body is positioned forward from the front and side center when worn. Misalignment is likely to occur. Therefore, there is a problem that wearing is not stable unless the shorts have a large foot pocket that is less affected by the movement of the legs.

  Moreover, even if the joint part of a front part and a back part is made into the waist | hip | lumbar side side back like patent document 3, or a patch is arranged on the front part like patent document 4, it will slide up and down at the time of wear Is not enough to prevent. In particular, in Patent Document 3, since the joint portion is only disposed on the back side of the waist and only the rubber band is disposed on the waist portion with respect to the positional deviation, the pile fabric portion that is difficult to stretch is used for the operation of standing and sitting. On the other hand, the back body will slide down without following.

  Accordingly, the present invention has been developed in view of the above-described problems, and provides an underwear excellent in a feeling of wearing in which the wearing position does not deviate even when repeated operations such as standing, sitting, and assembling legs are repeated. It aims at providing the undergarment applicable also as a girdle other than the shorts with a large leg part, and men's underwear.

  In order to solve the above-mentioned problems and achieve the object, the undergarment according to the present invention is composed of a single body fabric in which the main body fabric composed of the front body, the back body and the crotch is not hem-treated or edged. It is an underwear that does not have rubber that gives elasticity to the waist mouth part and the foot side part, and the side edges of the front body and the back body are joined to each other at the back side of the waist, In the expanded state, the line lengths L1 and L2 from the midpoints P1 and P2 of the lengths of both side edges of the front body to the center line C, and the midpoints P3 and P4 of the lengths of both side edges of the back body The length L3 of the back body is substantially the same length, and the center of the upper end of the back body is the point on the center line C at the top edge of the back body from the center point of the top edge of the front body to the center line C of the top edge of the front body. On the center line C that reaches the point, the patch is joined or Field processing is given and / or, characterized in that the gusset fabric is bonded to the crotch.

  Thereby, the underwear excellent in the feeling of wearing which a wearing position does not shift even if operation is repeated is realized. That is, each line length from the midpoint of the length of both side edges of the front body to the center line C in a state where the main body fabric is unfolded and the line length connecting the midpoints of the lengths of both sides of the back body are substantially the same. By setting the length, it is possible to obtain a pattern excellent in a feeling of wearing that is unlikely to cause a sliding or sliding down. In addition, by arranging the joint part of the body cloth at the back side of the waist side, it avoids the part where the body stretches and contracts, and improves the adhesion of the joint part to the body. Furthermore, with the application cloth affixed to the body cloth, the front edge of the gusset cloth attached to the crotch, or the mold processed part stopped from being stretched by the molding process, and both joint parts arranged on the back side part of the waist side The formed isosceles triangle maintains the balance of force and prevents movement in the left-right direction, so that the wearing position does not shift and move even when operations such as standing, sitting, and assembling legs are repeated. The joint part of the body fabric is inferior in elasticity compared to other parts, it is difficult to follow the movement of the skin, and when it is used for a movable part, a float occurs between the joint part and the skin, and the position shift occurs. By placing it behind the side of the waist where there is little movement, it is less susceptible to movement and also plays the role of suppressing the shrinkage of the body cloth in the length direction of the buttocks by the rigidity of the joint. Further, since the rubber is not used for the wearing part on the waist side and the opening part on the foot side (hem opening part, foot opening part), the closer to the opening part, the weaker the tightening force. When the fabric is stretched and the hip line (the intersection of the horizontal surface and the body surface at the back of the buttock) is located near the opening, it loses the strong tightening force in the central part in the length direction and the opening is in the central part. The opening part slides down or slides up. Therefore, by designing the hip line to be in the range of 1/3 of the central part when the joint part of the front body and back body is divided into three in the length direction, the hip line where force is applied is in the vicinity of the opening. Therefore, the opening is not pulled, the force to shift in the vertical direction is weakened, and an underwear with excellent wearing feeling is realized. In addition, by applying the patch to the abdomen, rigidity is imparted to the body fabric so that the fabric on the abdomen does not float, so that a support point for the force in the front body is formed. In the case where no patch is attached, by attaching the gusset fabric, the front body side edge of the gusset fabric becomes a support point for the front body part. In order to improve the feeling of wearing the gusset fabric, it is preferable to attach the gusset fabric by adhesion, but it may be sewn. The position of the isosceles triangle formed by these support points and both sides of the joint between the front body and the back body that are the support points of the back body prevents the joint from being pulled by the movement of the thigh. At the same time, it is possible to effectively prevent the entire underwear from shifting in the left-right direction.

  Here, in a state where the main body fabric is unfolded, the distance from the intersection P7 of the line connecting the upper ends of both side edges of the front body and the center line C to the upper center of the front body is the upper end of the front body and the upper end of the rear body. It is preferable that the upper end center point of the front body is located below the upper ends of both edges of the front body so as to be 10% to 15% of the distance to the center point.

  This avoids the influence of different body shapes, particularly the swelling of the abdomen, and prevents misalignment during wearing, thereby realizing an underwear with excellent wearing feeling.

  Here, the joint between the side edges of the front body and the back body at the back side of the waist may be wider than the joint width at the remaining joint, and the joint at the foot mouth. The width may be wider than the bonding width at the remaining bonding portion, and the patch may have a shape that increases in width toward the waist. Furthermore, the joint width at the foot opening and the foot mouth may be wider than the joint width at the joint between the foot opening and the foot mouth.

  As a result, it is possible to strengthen the tightening only at the waist-side wearing mouth, strengthening only the foot-to-mouth part, or tightening the wearing-out part and the foot-to-mouth part while preventing slipping up and sliding down. it can.

  The present invention can also be realized as a method for manufacturing underwear. That is, a cutting process to obtain a main body fabric composed of a front body, a back body, and a crotch by cutting a piece of body cloth that does not have hem treatment or edging, and an adhesive is applied to the main body fabric, and the center line of the main body fabric A bonding process in which a garment is bonded to the front body or / and a gusset cloth is bonded to the crotch so as to be symmetrical on C, and the front body is replaced with or after the bonding process. In the cutting process, including a molding process for forming a molded part by molding the body, and a joining process for assembling the main body fabric and joining both side edges of the front body and both side edges of the back body at the back side of the waist. The lengths L1 and L2 of each line from the midpoints P1 and P2 of the length of both side edges of the front body to the center line C in the state where the main body fabric is unfolded, and the midpoint P3 of the lengths of both side edges of the back body and Line length connecting P4 3 and a may substantially be configured as cutting the body fabric to the same length.

  As described above, the underwear according to the present invention has the length of each line from the middle point of the length of both side edges of the front body to the center line C in the state where the main body fabric is unfolded, and the length of both side edges of the back body. By making the line length connecting the midpoints substantially the same length, the wear balance is less likely to be raised or lowered when worn. In addition, since the joint part of the body cloth is arranged behind the side of the waist where there is the least movement, it can be made less susceptible to the movement of the body and the rigidity of the joint part suppresses the shrinkage of the length of the buttocks be able to. In addition, when a patch is applied to the abdomen of the body cloth, the abdomen of the body cloth becomes stiff, and unlike the joints, the body cloth is caused by the movement of the body by leaving only the body cloth above and below the patch. While preventing the fabric from rising, it adheres to the skin and prevents the entire undergarment from shifting up and down.In addition, the front cloth edge or the gusset fabric at the center of the front body or the front body edge of the gusset fabric and the back body The position of the underwear is stably determined by the positional relationship of the isosceles triangle formed at the time of wearing by the two joint portions, and the entire underwear is difficult to move in the left-right direction. In addition, by designing the hip line so that it is positioned in the range of the central part 1/3 of the front and back body in the bonding part length direction, the upper edge of the front body is removed from the abdomen while covering the hip. Furthermore, stability at the time of wearing increases.

  Hereinafter, modes for carrying out the present invention will be described.

  First, it demonstrates based on FIGS. The underwear body 1 is made of a single body cloth with a crotch 4 connecting the front body 2 and the back body 3, and is formed of a free-cut cloth that does not cause fraying even when cut and does not require edge trimming. ing. As the free cut fabric, it is preferable to use a two-way fabric to which an elastic yarn is welded. The two-way fabric may be composed of either a warp knitting or a weft knitting, but refers to a fabric having an elongation force of 80% or more in the warp direction and the weft direction.

  The underwear body 1 of the present embodiment shown in FIG. 1 has C as the center line from the front upper end center part 7 of the front body 2 to the rear upper end center part 8 of the rear body 3, and the front body side edges 2a, 2a The midpoints of the lengths are P1 and P2, respectively. The lengths of the lines L1 and L2 extended to the center line C, and the midpoints of the lengths of the back body side edges 3a and 3a are P3 and P4, respectively. When the connecting line length is L3, L1≈L2≈L3, that is, the respective line lengths are substantially the same. The midpoint P1 of the length of the front body side edges 2a coincides with the midpoint P3 of the length of the back body side edges 3a when the underwear body 1 is assembled, and the midpoint P2 coincides with P4. The intersection P5 on the center line C is such that the angle θ1 at which the center line C and the line lengths L1 and L2 intersect is the same as the angle θ2 at which the front body side edges 2a and the line lengths L1 and L2 intersect. Determined. Thus, the length L1 and L2 of each line from the midpoint of the length of both side edges 2a of the front body 2 to the center line C and the length of both side edges 3a of the back body 3 in a state where the main body fabric is unfolded. By making the line length L3 connecting the midpoints substantially the same length, it is possible to obtain a pattern with an excellent wear balance in which it is difficult for the shoe to rise or fall when worn.

  When joining the both side edges 2a, 2a of the front body 2 and the both side edges 3a, 3a of the back body 3, it is preferable to use an adhesive resin or sewing that does not impair stretchability such as a flat seamer. . The joint 5 which is a connecting portion between the front body 2 and the back body 3 is located behind the waist side surface with the least movement in the wearer's body.

  Since the joint portion 5 is inferior in elasticity as compared to other portions, if the joint portion 5 is located at a place where there is a lot of body movement such as the front surface or the front side surface, a displacement occurs. For example, if the joint 5 is positioned on the left and right sides of the abdomen, when the thigh is moved up, a compressive force is applied, and the joint 5 with poor elasticity is pushed upward, and one of the joints 5 The part will be separated from the skin and the wearing position will shift.

  If the joint 5 is positioned in the vicinity of the left and right vertices of the hip, when the thigh is moved up, the stretched force acts on the joint 5, and the joint 5 having poor stretchability is pulled downward. The wearing position shifts downward.

  Further, if the joint 5 is positioned forward from the center of the side surface of the waist, when the thigh is moved up, the joint 5 is bent into an L-shape, and the joint 5 is inferior in elasticity. Is pushed upward, and part of the joint 5 is separated from the skin, and the wearing position is shifted.

  When the body fabric leaves the skin, it means that it loses frictional force with the body. Since the body cloth and the skin try to fit in a place where the power is balanced, once the body cloth leaves the skin, the next place where the body cloth touches the skin is different from the resting position.

  In order to avoid these, the joint part 5 is disposed behind the side of the waist where the movement is the least.

  The joining part 5 is arrange | positioned to the waist | hip | lumbar part side back, and the shrinkage | contraction of the height direction of a buttocks can be suppressed with the rigidity of the joining part 5. FIG. However, if the joint part 5 is simply disposed at the back of the side of the waist, it is displaced in the left-right direction due to the movement of the thigh and the movement of bending the back.

  This is because the front body has no support point for the force, the fabric of the abdomen is lifted by the movement of bending the back, the frictional force with the skin is reduced, and the joint 5 is pulled by the movement of the thigh. This is because the entire underwear body 1 moves. Therefore, in order to increase the frictional force with the skin of the front body part so as to be a supporting point of the force in the front body part 2, a patch 6 described later is attached to the abdomen so that the fabric of the abdomen does not float up. 6 and the two joints 5 located on the back side of the body prevent the entire underwear from moving in the left-right direction. In the case of men's underwear, mold processing is applied instead of the patch 6 to stop the fabric of the lower abdomen. Further, by attaching a gusset fabric 14 mainly made of cotton to the crotch 4, the gusset fabric edge 14 a, which is the edge of the front body side of the gusset fabric 14, serves as a support point for the force of the front body part. .

  Unlike normal underwear, the underwear body 1 is not fixed to the waist with rubber, so it is worn by pressure applied to the body in a planar shape, but it stretches in the waist direction by 30% to 50% when worn. Therefore, the length direction tends to shrink. When shrinking in the length direction, the area becomes smaller and the sense of stability when worn is reduced.

  In the present embodiment, the patch 6 can suppress the contraction in the length direction of the abdomen at the time of wearing, and can suppress the contraction in the length direction of the buttocks at the two joint portions 5 and 5 on the back side of the waist. The contact area is maximized to increase stability.

  The application cloth 6 to be affixed to the abdomen is preferably the same two-way cloth as the body cloth, but may be other stretchable cloth. Further, it may be bonded to the inner surface of the underwear body 1 or may be bonded to the outer surface of the underwear body 1. The pasting position is suitable on the center line C. Moreover, the thing of the shape symmetrical with respect to the centerline C is preferable, and the partial adhesion | attachment including the whole surface or an edge part may be sufficient. In order to adjust the adhesion to the shape and movement of the body, dot adhesion is preferable in order to have an allowance for expansion and contraction, but a tape-like adhesion may be used. In the case of tape-like adhesion, it is necessary to have elongation and recovery properties close to the underwear body 1. This is because if the adhesive tape is poorly stretched or recoverable, the bonded portion will not recover after wearing and will be in a waved state. The adhesive resin is preferably a polyurethane resin, but may be an elastic nylon resin or the like.

Including the case where the bonding between the front body 2 and the back body 3 of the bonding portion 5 is dot bonding with an adhesive resin, dot bonding here refers to applying an adhesive in a circle and arranging the dots at equal intervals. It is arrange | positioned so that it may adhere | attach. In each example described later, the circular diameter is 2 mm, and the area ratio of the designed adhesive is 55%. FIG. 6 is a diagram for explaining the resin area ratio of dot adhesion, and the calculation of the area ratio of the adhesive was performed as follows.
(formula)
Equilateral triangle area: S1 S1 = i × h ÷ 2
h = √3 × i ÷ 2
Dot area: S2 S2 = π × r2 ÷ 2
Resin area ratio: Ar Ar = S2 ÷ S1 × 100 = (π × r2 ÷ 2) ÷ (i × h ÷ 2) × 100
= (π × r2) ÷ (i × h) × 100 = (π × r2) ÷ (i2 × √3 ÷ 2) × 100
For calculating the distance between dots from the resin area ratio, calculate the distance between dots by calculating the length “i” of one side of the unit surface (regular triangle) from the adopted area ratio, and calculate the offset value (height of the regular triangle) The calculation of h) is performed by calculating h from the distance “i” between dots.
In addition, since the adhesive spreads somewhat after bonding, the area after bonding becomes large. The diameter of the circle is preferably in the range of 1.6 mm to 2.4 mm. The area ratio of the adhesive is desirably 30% to 70%. However, depending on the performance of the adhesive, it may be 1.6 mm or less and the area ratio is 30% or less. The diameter and area ratio of the dot circle should be set in the above range. If the dot circle diameter or area ratio is too large, the stretchability of the joint will be impaired and misalignment will easily occur. This is because if the diameter or area ratio is too small, the adhesive strength is insufficient, and there is a risk of peeling off during wearing or washing.

  As shown in FIG. 5A, the positional relationship between the patch 6 and the joint portion 5 of the body cloth is preferably arranged so that the center of the patch 6 is positioned at the apex of the isosceles triangle when worn. This is because the position of the underwear is stably determined and the entire underwear is difficult to move in the left-right direction.

  As shown in FIG. 5B, the positional relationship between the joint portion 5 between the gusset fabric 14 and the body fabric is preferably arranged so that the front body edge 14a of the gusset fabric 14 is positioned at the apex of the isosceles triangle when worn. Accordingly, the position of the underwear is stably determined, and the entire underwear is difficult to move in the left-right direction.

  Designed so that the wearer's hip line comes to the center part 16 in the joint length direction, which is the central part when the joint part 5 is divided into three parts in the length direction when worn, and tightening force on the hip line where the fabric is stretched most Avoid moving the weak fabric edges. In order to stably hold the portion where the fabric is stretched most, it is necessary to have the same tightening force around the portion where the fabric is stretched (here, the upper and lower regions of the hip line). In the case of fabric, the tightening force becomes weaker toward the edge, so it is not preferable that the wearer's hip line comes to the edge in the vertical direction (length direction). Therefore, when the joint portion 5 is divided into three in the length direction, a region that becomes 1/3 from each of the upper edge portion and the lower edge portion is avoided, and the wearer's center portion 16 in the joint height direction, which is the central portion, is avoided. It is designed so that the hip line is placed. The reason why the joint portion 5 is divided into three in the length direction is that the shape of the human buttock is various and covers as many human buttock shapes as possible.

  The reason why the position of the hip line is defined by the joint portion 5 is that, as described above, the length of the heel portion is maintained by the rigidity of the joint portion 5.

  A person's abdomen swells unevenly. In the present embodiment, the hip is positioned in the center of the length direction and covered with the back body 3 to increase the sense of stability at the time of wearing, but when the upper end of the front body 2 is matched with the upper end of the back body 3 as it is, When a person who is inflated wears, a force that shifts downward will work. In order to avoid the influence of such a difference in body shape, the upper edge of the front body 2 is curved below the upper edge of the back body 3 when worn so that the upper edge of the front body 2 is curved from the upper edge of the back body 3 Like to do. Referring to the developed view of FIG. 1, an intersection of a line connecting the upper ends of both side edges 2a, 2a of the front body 2 and the center line C is P7, and the front body 2 on the center line C from the intersection P7. It is designed so that the distance to the front body upper end center part 7 is 10 to 15% of the distance from the front body upper end center part 7 to the rear body upper end center part 8 on the center line C.

  Instead of rubber, elastic resin is applied to the fabric to increase the tightening force of the part, stabilizing the hip line where the fabric is stretched most within the range of 1/3 from the edge, It is also possible to stabilize it by placing the upper edge on the abdomen. In that case, if the tightening force is extremely increased, it is not intended to provide a comfortable feeling without the original tightening feeling, so it is better to increase the application density of the elastic resin from the center to the edge. For example, the central portion is a region having a coating density of 30%, and the edge portion is a region having a coating density of 50%.

  By these, even if it repeats operation | movements, such as standing, sitting, and crossing a leg, the position of the underwear does not shift | deviate and the underwear excellent in the feeling of wear can be obtained.

  Here, the underwear body fabric is a free-cut fabric that does not require edge trimming, but the two-way fabric is coated with an elastic resin (urethane resin, etc.) that prevents the fabric from expanding and contracting as much as possible. You may use what made the edge unnecessary.

  The underwear configured in this way is manufactured, for example, by the following process.

  First, a free cut fabric that does not require edge trimming, that is, a single body fabric that does not undergo hem treatment or edging, is cut to obtain a main fabric composed of a front body, a back body, and a crotch. In this cutting process, the length L1 and L2 of each line from the midpoint of the length of both side edges 2a of the front body 2 to the center line C in the state where the main body cloth is unfolded, and the length of both side edges 3a of the back body 3 The line length L3 connecting the middle points is cut so as to be substantially the same length. In addition, the upper edge of the front body 2 is bent from the upper edge of the front body 2 from the intersection P7 of the line connecting the upper ends of both side edges 2a, 2a of the front body 2 and the center line C, and the center of the upper end of the front body 2 7 from the upper end of both edge portions 2a of the front body 2 so that the distance to 7 is 10% to 15% of the distance from the upper center portion 7 of the front body to the upper center portion 8 of the back body. Cut to be positioned below.

  Next, an adhesive is applied to the main body cloth, and the application cloth 6 is bonded to the front body 2 and the gusset cloth 14 is bonded to the crotch 4 so as to be symmetrical on the center line C of the main body cloth. Instead of the bonding process of bonding the patch 6 to the front body 2, a molding process may be performed in which the front body 2 is molded to form the molded portion 18, or the patch 6 is bonded to the front body 2. It is also possible to proceed to the molding process after the bonding process.

  Finally, the underwear of this embodiment is obtained through the joining process of assembling the main body fabric and joining the side edges 2a, 2a of the front body 2 and the side edges 3a, 3a of the back body 3 at the rear side of the waist.

Hereinafter, specific examples 1 to 12 will be described in further detail. In the underwear main body 1, the body fabric is a free-cut fabric that does not cause fraying even if it is cut and does not require edge trimming, and is knitted with a two-way fabric that stretches by 80% or more in the background direction. The center line from the upper end central portion 7 of the front body 2 to the lower end central portion 8 of the rear body 3 is C, the midpoints of the lengths of the front body side edges 2a and 2a are P1 and P2, and the center line C When the extended line lengths L1 and L2 and the midpoints P3 and P4 of the lengths of the side edges 3a and 3a of the back body and the line length L3 connecting the two points are L1≈L2≈L3, Are the same length, the angle θ1 at which the center line C and the line lengths L1 and L2 intersect, and the angle θ2 at which the front body side edges 2a and the line lengths L1 and L2 intersect are the same. A point and a line connecting the upper ends of both side edges 2a, 2a of the front body 2 and the center line C Designed so that the distance from the intersection P7 to the front upper end central part 7 is 10 to 15% of the distance from the front upper end central part 7 to the rear upper end central part 8 of the rear body 3 Since these are common, description thereof will be omitted in each embodiment, and only the difference in the positional relationship between the abdomen application cloth and the body cloth will be described.
Example 1
As shown in FIG. 1, the joint part line 9 of the body cloth and the application cloth side edge line 10 are parallel to each other, the shape of the application cloth 6 is a deformed hexagonal shape, and is bonded to the inner surface side. Since the distance to the application cloth 6 is substantially equal from the top to the bottom, the waist portion and the hip portion are tightened equally in a well-balanced manner. Further, the gusset fabric 16 is bonded to the inner surface side of the crotch 4 so as to function as women's underwear.
(Example 2)
As shown in FIG. 7, the application cloth 6 having the same shape as that of the first embodiment is similarly bonded to the inner surface side, omits the gusset fabric 16, and is applied to male underwear. Is.

Example 3
As shown in FIG. 8, there is no patch 6 and the gusset fabric 16 is bonded to the inner surface side of the crotch 4, which makes it feel the least tight in the embodiment, and is applied to women's underwear. The

Example 4
As shown in FIG. 9, instead of the patch cloth 6, a molded portion 18 is formed by molding.

The spreading lower end part is adhered to the inner surface side in a substantially arrow shape formed in an arc shape, and in this case, the distance becomes longer as the distance from the joint line 9 of the body cloth to the patch 6 becomes closer to the waist line. Therefore, there is an effect of assisting the feeling of tightening the hip part and an effect of stabilizing the position of the inner side surface on the front side of the crotch part.
(Example 6)
As shown in FIG. 11, the intersection O of the joint line 9 of the body cloth and the extension line of the baffle side edge line 10 is the upper and lower sides, and the shape of the batter 6 is a rhombus and bonded to the surface side. ing. In this case, the distance from the joint line 9 of the body cloth to the patch 6 is the shortest at the position connected to the apex of the hip, and the effect of tightening the hip portion is enhanced.
(Example 7)
As shown in FIG. 12, the intersection point O of the joint line 9 of the body cloth and the extension line of the batter side edge line 10 is parallel to the upper part and the middle, and the shape of the batter is approximately Y-shaped. On the side. In this case, the distance from the joint line 9 of the body cloth to the application cloth 6 is the longest at the position connected to the apex of the hip, and the hip can be given a space.
(Example 8)
As shown in FIG. 13, the intersection O of the joint line 9 of the body cloth and the extension line of the application cloth side edge line 10 is on the upper side, and the application cloth 6 has a substantially trapezoidal shape on the outer surface side. In this case, the distance from the joint line 9 of the body cloth to the application cloth 6 is such that the distance becomes shorter as the waist line is closer, and there is a feeling of tightening of the waist.
Example 9
What is shown in FIG. 14 is a modification of FIG. 12, in which a roughly Y-shaped patch 6 is bonded to the surface side, and the lower end of the patch 6 is used as the opening 11 without sewing. By making a cut in the underwear main body 1 and providing the second opening 12, it is possible to make a small use.
(Example 10)
FIG. 15 shows a modification of FIG. 13 in which a substantially trapezoidal patch 6 is bonded to the surface side, and the side edge of the patch 6 is not sewn but the opening 11, and the underwear By providing the body cloth opening 12 which is the second opening obtained by cutting the main body 1, it is possible to make a small use.
Example 11
If the dough is pulled beyond a certain level, the end of the dough will curl. What is shown in FIG. 16 is a modification of FIG. 13, and by reducing the area of the upper part of the batter 6, the tightening of the wearing part is loosened and the tension at the time of wearing is made looser than in Example 8. . Moreover, in the both side edges 3a of the back body 3, the back body upper-end center part 8 at the time of wearing is outside the back body side edge extension line 17, which is an imaginary line extending P3 and P4 from the end of the foot part. It has a shape that is positioned, and it has an effect to further suppress the occurrence of curling of the fabric in the wearing mouth part by giving a margin to the wearing mouth part on the waist side.
(Example 12)
By changing the bonding width 13 of the cloth, various effects can be obtained as in the case of changing the shape of the application cloth. In the example shown in FIG. 17, the joint widths of Examples 1 to 10 are all 7 mm from the waist to the foot. In order to increase the overall tightening feeling, it is preferable to uniformly widen the joining width 13b as shown in FIG. In order to strengthen the tightening feeling only at the waist, it is preferable to increase the joining width 13c only in the vicinity of the waist as shown in FIG. On the contrary, in order to strengthen the feeling of tightening only the foot mouth part, the joining width 13d only in the vicinity of the foot mouth part may be increased as shown in FIG.

  However, when only the foot mouth part is reinforced, the wear mouth part on the waist side becomes unstable and tends to slide down when worn, so in that case, the shape of the patch 6 is worn as in Examples 7-11. It is necessary to make the mouth side wider and balance it. In order to strengthen the feeling of tightening both the foot mouth part and the foot mouth part, it is preferable to increase the joint width 13e in the vicinity of both the foot mouth part and the foot mouth part as shown in FIG. In addition, a hip-up effect can be obtained by using a highly elastic fabric such as a power net as the fabric of the underwear body in this pattern.

  As described above, the undergarment according to the present invention has been described based on various examples. However, the present invention is not limited to these, and various objects can be achieved without departing from the gist of the present invention. The design can be changed, and these are all included in the technical scope of the present invention.

  INDUSTRIAL APPLICABILITY The present invention can be applied to all underwear having a crotch portion that is worn in close contact with the body, such as shorts, girdle, and briefs.
