Further, the distance (S) from the narrowest bottom part of the central-lower piece (46) to a part corresponding to a buttock of a wearer is designed to form a rapid angle of inclination in consideration of the shape of the buttocks, so that the narrowest bottom part provides comfort to the wearer and the central-lower piece (46) sufficiently supports the buttocks.
• the left/right mesh tapes (47, 47a) are connected to the waist band (20), which is designed to have curved shape so that the middle portion thereof, rather than the left and right side portions, is lowered.
• the left/right mesh tapes (47, 47a) are also connected both to the one-way stretchable left/right-upper-front pieces (41, 42), which are not stretchable in the upward and outward diagonal directions Z and Z' from the lower portion of a vertical central axis in the front sheet part, and to the left/ right-upper-rear pieces (51, 51a) extending forwards from the rear side of the underpants.
• the left/right mesh tapes (47, 47a) release the transmission of lifting and shaping functional strong pressure to the front sheet part.
• the middle mesh tape (48) releases both the lifting and shaping functional pressure reduced by the left/ right mesh tapes (47, 47a) and pressure acting both on the left/right-upper-front pieces (41, 42) and on the left/right scrotal pieces (44, 45), thus preventing the pressure from being strongly exerted on the scrotal part of the wearer's body.
• the middle mesh tape (48) also provides improved ventilation effects to the scrotal part of the wearer's body, thus preventing the scrotal part from becoming wet with sweat and reducing the body temperature of the wearer, thereby being good for the health of the wearer.
• FIG. 15 illustrates the states of expansion and contraction in the pieces of the underpants shown in FIG. 11, which correspond to respective parts of the wearer's body.
• FIG. 16 illustrates the states of expansion and contraction in the patterns of the left/right-upper-rear pieces, which have a symmetrical structure, as shown in FIG. 11, and are removed from the front sheet part of the underpants.
• FIG. 19 is a perspective view illustrating the rear part of the underpants according to the present invention when a person wears the underpants.
• the left/right-upper-rear pieces (51, 51a) and the waist band (20) connected to the upper ends of the left/right-upper-rear pieces (51, 51a) are designed to have a symmetrical curved shape.
• the rubber waist band (20) which is designed to have a curved shape to lower the middle portion thereof rather than the left and right side portions, is stretched in the arrow directions A, A' as shown by the dotted line in FIG. 15, so that the middle portion (1-A) of the waist band, which is placed lower than a horizontal line extending between the left and right side portions, is lifted upwards.
• the underpants provide an effect of lifting and shaping the buttocks.
• junction parts (2- A) between the lower end of the waist band (20) and the upper ends of the left/right-upper-rear pieces (51, 51a) are designed to have curved shapes, which are curved upwards. Due to the connection of the waist band (20) to the upper ends of the left/right-upper-rear pieces (51, 51a), when the underpants are worn by a person, the junction parts (2- A) are moved downwards by the force of the waist band until they form a horizontal line. Thus, the junction parts (2- A), which have been moved downwards, become enough and naturally support and shape the buttocks in a three-dimensional shape. Particularly, as shown in FIG.
• the left/right-upper-rear pieces (51, 51a) are not stretchable in the upward and outward diagonal directions from the lower portion of the vertical central axis, and thus they can prevent the buttocks from spreading out.
• the opposite sides (1-C, 1-C) of the waist band function as the hubs of the force, so that the force uniformly acts in the upward and outward diagonal directions D and D' from the lower portion of the vertical central axis along a symmetrical Y-shaped line of action, thus lifting and shaping the buttocks.
• the curved shapes of the junction parts (2-B) between the lower ends of the left/ right-upper-rear pieces (51, 51a) and the upper ends of both the left/right-lower-rear pieces (52, 52a) and the left/right middle pieces (53, 53a) cooperate with the curved shapes of the left/right middle pieces (53, 53a) and support the curved shapes of the buttocks, thus maintaining the beautiful line of the buttocks.
• the left/right-upper-rear pieces (51, 51a) have excellent expansion and contraction and high restoring force at the pyramid portion (E) shown in FIG. 16, so that, when a wearer is in a standing pose, an effect of lifting and shaping the buttocks is provided by the force naturally acting in the Y-shaped line of action. Further, due to the excellent expansion and contraction of the pyramid portion (E), when the wearer is in a seating pose, in which the surface area of the buttocks is about 1.5 times as large as the surface area thereof in the case of the standing pose, the underpants efficiently and naturally cover the expanded buttocks.
• the left/right middle pieces (53, 53a) are designed to have curved shapes such that they efficiently and naturally support the curved buttocks and are not stretchable in vertical directions.
• both the force acting upwards from the middle part (1-A) of the waist of a wearer and the force diagonally acting upwards from the left/ right-upper-rear pieces (51, 51a) act vertically in the left/right middle pieces (53, 53a), so that the left/right middle pieces (53, 53a) efficiently support the portions of the buttocks, which may easily droop.
• the left/right middle pieces (53, 53a) have excellent expansion and contraction and high restoring force in horizontal directions, thus efficiently and naturally supporting the enlarged buttocks when the wearer is in a seating pose.
• the lower portions (4- A) of the left/right middle pieces (53, 53a) are designed to have almost horizontal shapes through a horizontal designing technique rather than a typical diagonal shapes, thus efficiently covering and supporting the most plump parts of the buttocks.
• the left/right-lower-rear pieces (52, 52a) are designed to be stretchable in directions opposite to the stretchable directions of the left/right middle pieces (53, 53a), thus strongly pressing the buttocks and providing the beautiful line of the buttocks.
• the left/right- lower-rear pieces (52, 52a) cooperate with the left/right-upper-rear pieces (51, 51a), thus efficiently and naturally covering and supporting the enlarged buttocks.
• the lower ends of the left/ right-upper-rear pieces (51, 51a) are connected both to the left/right-lower-rear pieces (52, 52a) and to the left/right middle pieces (53, 53a).
• the underpants provide an effect of lifting and shaping the buttocks and maintain the beautiful line of the buttocks, and also provide comfort to the wearer.
