DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for manufacturing underwear such as three-dimensional panties and briefs.

Prior Art and its Problems Conventionally known underwear such as panties and briefs has a cloth part that covers the lower abdomen and a cloth part that covers the buttocks, as shown in Japanese Patent Laid-Open No. 52-21950. The shape is created by projecting the lower abdomen and buttocks from the front or back, and the overall bulges of the lower abdomen, sides, and buttocks in the human body are not taken into consideration. Furthermore, since the conventional underwear described above is of a shallow type in which the upper front edge is located below the peak of the abdominal bulge when worn, if the entire upper circumference of the underwear is made in a horizontal straight line, When I bend my waist, the back of my underwear tends to slide down. In order to prevent this, it is necessary to form the underwear so that the upper edge of the rear part is above the buttocks, and if this is done, the upper edge of the underwear will inevitably slope downward from the buttocks side to the abdomen side. Not only does it make you look bad, but it also makes it uncomfortable to wear. Furthermore, when wearing the above-mentioned conventional underwear, the cloth part that covers the buttocks simply covers the valley between the left and right buttocks in a flat manner, and the lower end of this part sag and wrinkles. This also impairs the aesthetic design of the underwear, and since it does not fit tightly along the left and right buttocks and the valley between the left and right buttocks, it also has the disadvantage of not being comfortable to wear.

Incidentally, Japanese Patent Application Laid-Open No. 127492/1983 discloses sanitary underwear that is designed to prevent sanitary cotton from falling backward. This underwear consists of a first piece that diagonally covers part of the left half of the left buttock from the center line of the human abdomen, leaving the buttocks intact, and a first piece that covers part of the right half of the right buttock from the center line of the abdomen, leaving the buttocks intact. a second piece that covers the body diagonally; a third piece that is interposed between the first piece and the second piece and covers the center part of the buttocks and the bottom of the buttocks; and a fourth piece that covers the groin area. . The third piece is a narrow piece of cloth having approximately the same width as the fourth piece before being sewn together, and has a deep V-shaped recess formed at one end facing the fourth piece. When manufacturing underwear, both sides of the V-shaped recess are bent upward to make the whole into an inverted T-shape, and the lower end and the fourth piece, which is made up of the entire recessed part that opens almost horizontally, are folded upward. Also, both side ends of the third piece are sewn to the rear ends of the first piece and the second piece, and the lower ends of both sides following the V-shaped recess are sewn to the annular body for forming the leg hole. . Therefore, when wearing this sanitary underwear, there is enough room to fit around both the left and right buttocks, but on the other hand, the seam part of the third and fourth pieces is located considerably above the bottom edge between the left and right buttocks. Because of this, the underwear does not fit tightly into the valley between the left and right buttocks, so it is difficult to say that it is excellent in terms of appearance or comfort.

An object of the present invention is to eliminate the above-mentioned drawbacks and provide a method for manufacturing underwear such as three-dimensional panties and briefs that are aesthetically pleasing and comfortable to wear.

Means for Solving Problems In order to achieve the above object, the method for manufacturing underwear according to the first invention includes: an abdominal piece that covers the lower abdomen, a buttock piece that covers both left and right buttocks, and a crotch piece that covers the groin area. In manufacturing underwear, a protrusion extending in the left-right direction is formed on both sides of the upper part of the abdomen piece, and a protrusion part extending in the left-right direction and diagonally upward is formed on both sides of the upper part of the buttock piece, and the edges of these protrusions are The lengths of the buttock pieces should be the same, and each piece should be sloped upward toward the center line, and the upper edge of the buttock piece should be curved so that it is most concave on the centerline of the piece, and the lower ends of the buttock pieces should be sewn together. and one end of the groin piece, so as to create a gap that is bilaterally symmetrical with respect to the center line of the buttock piece and the groin piece and whose width gradually increases toward the center line when these pieces are butted together,
The lower end of the buttock piece is formed into a concave shape, the protruding parts of the abdomen piece and the buttock piece are sewn together at their edges, and the lower end of the buttock piece is sewn to one end of the crotch piece so as to eliminate the above-mentioned gap. The buttock piece and the crotch piece are formed so that when worn, the seam part between the buttock piece and the crotch piece is located at approximately the lowest end between the left and right buttocks.

Further, the method for manufacturing underwear according to the second invention includes an abdominal piece that covers the lower abdomen, a buttock piece that covers both left and right buttocks, and a crotch piece that covers the crotch area, and when worn, the upper edge of the abdominal piece is attached to the abdomen. In manufacturing shallow underwear located below the peak of the bulge, protrusions extending horizontally and diagonally upward are formed on both sides of the upper portions of the abdomen piece and buttocks piece, and these protrusions are attached to the edges. The buttocks to be sewn together are made to have the same length and slope upward toward the center line of each piece, and the upper edges of the abdominal piece and the buttock piece are curved so that they are most concave on the center line of both pieces. Between the center part of the lower end of the piece and one end of the crotch piece, so as to create a gap in which the buttock piece and the crotch piece are bilaterally symmetrical with respect to the center line and whose width gradually increases toward the center line when they are butted together. The lower end of the buttock piece is formed into a concave shape, the protruding parts of the abdomen piece and the buttock piece are sewn together at their edges, and the lower end of the buttock piece is sewn to one end of the crotch piece so as to eliminate the above-mentioned gap. The buttock piece and the crotch piece are formed so that when worn, the seam part between the buttock piece and the crotch piece is located at approximately the lowest end between the left and right buttocks.

Furthermore, the method for manufacturing underwear according to the third invention includes: an abdominal piece that covers the lower abdomen; a buttock piece that covers both the left and right buttocks;
In manufacturing deep underwear that consists of a crotch piece that covers the groin area, and in which the upper edge of the abdominal piece is located above the peak of the abdomen's bulge when worn, a protrusion that extends left and right on both sides of the upper part of the abdominal piece is used. On both sides of the upper part of the buttock piece, protrusions extending in the left-right direction and obliquely upward are formed, and the edges of these protrusions are made to have the same length and are inclined upwardly toward the center line of each piece. In addition, the abdominal piece is curved so that it is most protruding on the center line, and the upper edge of the buttock piece is curved and most concave on the center line of the same piece. The lower end of the buttock piece is shaped concavely so that when the ends of the buttock pieces are butted together, a gap is created that is symmetrical with respect to the center line of the buttock piece and the groin piece and whose width gradually increases toward the center line. The protruding parts of the abdomen piece and the buttock piece are sewn together at their edges, and the lower end of the buttock piece is sewn to one end of the crotch piece so that there is no gap, and when the underwear is worn, the protruding parts of the buttock piece and the crotch are sewn together. The buttock piece and the groin piece are formed such that the stitched portions of the pieces are located approximately at the lowest end between the left and right buttocks.

In particular, in the embodiment of the first invention, the upper edge 13a of the abdominal piece 3 is
The curved shape is the most prominent on the center line.

Effects of the Invention According to the method for manufacturing underwear of the first invention, when manufacturing underwear consisting of an abdominal piece that covers the lower abdomen, a buttock piece that covers both left and right buttocks, and a crotch piece that covers the groin area, it is possible to A protrusion extending in the left-right direction is formed on both sides of the upper part, and a protrusion part extending in the left-right direction and diagonally upward is formed on both sides of the upper part of the buttock piece, and the edges of these protrusions are made to have the same length, and the center of each piece is formed. The upper edge of the buttock piece has a curved shape that is most concave on the center line of the buttock piece. The protrusions extending diagonally upward in the left-right direction are pulled down by the rearward protrusion of the buttocks, and the upper edges of these become aligned horizontally with the upper edges of the inverted buttock pieces. As the protrusions on both sides of the buttock piece descend, a space is created in the buttock piece to tightly wrap the upper portions of both the left and right buttocks that protrude rearward.

In addition, since the edges of the protruding parts of the abdominal piece and the buttock piece are made to have the same length and are sloped upward toward the center line of each piece, the sutured part of the protruding part It becomes close to the lower back.

Furthermore, between the lower end of the buttock piece and one end of the groin piece to be sewn together, create a gap that is symmetrical with respect to the center line of the buttock piece and the groin piece and whose width gradually increases toward the center line when they are butted together. The lower end of the buttock piece is formed into a concave shape so that the lower end of the buttock piece is created in a concave shape, and the lower end of the buttock piece is sewn to one end of the crotch piece so that there is no gap, so a vertical depression is formed on the center line of the buttock piece. At the same time, bulges are formed on both sides. The buttock piece and crotch piece are formed so that the seam between the buttock piece and the crotch piece is located almost at the lowest end between the left and right buttocks when the underwear is worn, so the underwear is strongest on the center line of the buttock piece when worn. In addition, as one moves from the center line to both sides, the crotch is gradually pulled to one side, and the buttock piece is tightly attached to the valley between the left and right buttocks, and the underwear is engaged with the human body at this part. The underwear does not shift due to bending and stretching movements of the waist and other human body movements, and the bottom of the buttocks does not sag or wrinkle. Furthermore, the bulges on both sides of the vertical depression formed in the buttock piece are connected to the loose parts of the buttock piece created by the lowering of the protrusions on both sides, and these bulges are tightly attached along the left and right buttocks that bulge out in a spherical shape. wrap around. Therefore, the underwear fits the three-dimensional shape of the buttocks and presents a beautiful appearance.

According to the method for manufacturing underwear of the second invention, in addition to the effects of the first invention, the following effects are achieved. In other words, when wearing conventional shallow so-called bikini-type underwear, the upper edge of the abdominal piece is located below the peak of the abdominal bulge, so if the upper edge of the underwear is in a horizontal straight line when worn, When I bend my waist, my underwear moves down and tries to slide down. In order to prevent this, the upper edge of the buttock piece must be placed above the buttocks, and if this is done, the upper edge of the underwear will inevitably slope downward from the buttocks side to the abdomen side, resulting in a poor appearance. becomes worse. However, the second
In the method of the invention, in particular, protrusions are formed on both sides of the upper portions of the abdominal piece and the buttock piece, respectively, extending in the left-right direction and diagonally upward, so that the upper edges of the abdominal piece and the buttock piece are aligned at the center of both pieces. Because it has a curved shape where the line is the most concave, when worn, the protruding parts of the abdomen piece and buttocks piece that are sewn together will be pulled down by the rearward bulge of the buttocks. The upper edges of the abdominal and buttock pieces become horizontally straight. As in the case of the first invention, since the buttock pieces are fixed by sinking into the valley between the left and right buttocks, the above-mentioned horizontal-linear state is maintained even when the waist is bent, and the underwear when worn is A beautiful appearance can always be maintained.

According to the method for manufacturing underwear of the third invention, in addition to the effects of the first invention, the following effects can be achieved. In other words, deep underwear is generally worn by middle-aged or older people who have a protruding abdomen.
With conventional underwear, the protruding abdomen is pulled downward, creating a downward slope from the buttocks to the abdomen, causing the abdomen to protrude out of the underwear.
In the method of the invention, in particular, the upper edge of the abdominal piece is curved so that the center line of the piece is most protruding, so that when wearing deep underwear, the abdominal piece stretches forward along the protruding abdomen. It is swollen and its upper edge is horizontal.
It becomes straight and the height of the upper edge of the abdominal piece is
As the protrusions on both sides descend, the height becomes equal to the height of the buttock piece, which becomes horizontally straight. Therefore, when worn, the upper periphery of the underwear remains horizontal and straight, giving it a good appearance.
