underwear

Abstract

Undergarments help you maintain an upright posture with your spine straight. [Solution] The undergarment is constructed using a minimum of 24 pieces of fabric, with the contours of each piece of fabric consisting of convex and concave sections and straight lines. By connecting adjacent pieces of fabric with convex and concave sections, or with straight lines, the resistance of the fabric is controlled, making it easy to maintain an upright posture.

Description

Technical Field

[0001] The present invention relates to underwear. In the present invention, except for the two pieces of fabric at the center of the back, it is symmetric about the left and right, so the claims for the symmetric parts are omitted. The threads for producing and connecting each piece of fabric and the buttons used at the front body when wearing are also omitted.

Background Art

[0002] The fabric used in the present invention classifies the sides in contact with adjacent fabrics into three types: convex parts, concave parts, and straight lines.

[0003] General underwear has a structure that covers a certain area such as the left and right front bodies, the left and right back bodies, the collar, and the left and right sleeves with the same piece of fabric. When trying to maintain a posture with the back straight while wearing general underwear, the underwear does not have the function of assisting in maintaining that posture with the back straight.

[0004] The present invention is composed of multiple pieces of fabric, and when trying to maintain a posture with the back straight while wearing it, it can easily maintain that posture with the back straight.

[0005] The fabric constituting the present invention is designed with a combination of convex parts, concave parts, and straight lines between adjacent fabrics. The convex parts have roundness, and conversely, the concave parts are depressions. When a pushing force is applied from the concave part towards the convex part due to the movement of the body, the convex parts, due to their roundness, generate resistance against shrinking.

[0006] When a pushing force is applied from the convex part towards the concave part, no resistance against shrinking is generated in the concave part.

[0007] No difference in resistance like that between convex and concave parts occurs between the sides being pushed and the side being pressed regardless of which side is pushed between straight lines.

[0008] By obtaining a difference in resistance through the combination of convex parts, concave parts, and straight lines, it is possible to easily create a posture with the back straight.

Summary of the Invention

[0009] When a person is fatigued, they tend to lean forward. Not only do the right and left halves of the body contract forward simultaneously and equally, but depending on the person and the degree of fatigue at the time, they may also twist from right to left as they fall forward. Or they may twist from left to right as they fall forward. Alternatively, wearing thick, wide diapers can force the hip joints to spread apart, making it easier to fall backward. If this posture remains unbalanced, it will only generate further fatigue. [Means for solving the problem]

[0010] In underwear, areas that have a significant impact on the body are not divided into four sections, such as the left and right front panels and left and right back panels, as in typical underwear. Instead, these areas are constructed from multiple pieces of fabric. Each of these multiple pieces of fabric has convex, concave, and straight edges, and by appropriately combining them, resistance generated in response to body movements is controlled, which helps maintain posture. [Effects of the Invention]

[0011] According to this invention, people who tend to lean forward will be able to straighten their spine and more easily maintain their center of gravity in the center of their body. People who tend to lean backward will be able to straighten their spine and more easily maintain their center of gravity in the center of their body. [Brief explanation of the drawing]

[0012] [Figure 1] This is a diagram of the underwear of the present invention. [Figure 2] This is a perspective view of the underwear of the present invention. [Figure 3] This is a perspective view of the underwear of the present invention from the back. [Modes for carrying out the invention]

[0013] Let's explain using Figure 1. The main body for implementing the present invention consists of 24 to 40 pieces of fabric. Evaluation of prototypes based on the present invention revealed that 24 pieces of fabric provided the fewest number of pieces while still achieving the desired effect.

[0014] Therefore, the basic structure consists of 24 pieces as shown in Figure 1. Since 24 pieces of fabric is the minimum number of fabrics required to carry out this invention, fabrics A, B, C, D, E, F, G, H, I, J, and K are made from different fabrics and are symmetrical on the left and right sides. Since L and M are located in the center of the back bodice, they are made from a single piece in the center, rather than one piece on each side. Thus, the structure consists of 24 pieces.

[0015] Based on the findings of this invention, the desired effect cannot be obtained if the invention is constructed with fewer than 24 pieces of fabric. The effect can be strengthened by constructing the main body with more than 24 pieces of fabric.

[0016] The 24 pieces of fabric shown in Figure 1 are each independent materials. By connecting them, they retain their individual functionality while being able to function as a single garment.

[0017] The fabrics used in this invention must maintain their independence from one another. Due to the different shapes of the concave, convex, and straight edges designed on each fabric, a difference in resistance is created when the fabrics touch each other. Adjacent fabrics touch each other at the convex and concave points, and straight edges touch each other. When the wearer's posture tends to collapse due to fatigue, the multiple convex points within a single garment resist the force acting on the body as it collapses, helping to maintain an upright posture with ease. In the relationship between the convex and concave points, when pushing from a convex point towards a concave point, a force is applied from the convex point towards the concave point. In this case, the concave point that receives this force has little resistance to it. Because the resistance is weak, when a part of the body beneath these two layers of fabric moves from the convex point towards the concave point, the effect of hindering that movement is weak.

[0018] Conversely, when pressure is applied from a concave to a convex area, a force is applied that pushes the convex area inward. In this case, the convex area experiences strong resistance to this force. Because of this strong resistance, the body parts beneath the two layers of fabric also experience stronger resistance when moving from the concave to the convex area.

[0019] At the edges where two straight lines meet, there is no difference in resistance between the pushing side and the pushed side that affects the body.

[0020] The fabric constituting this invention is divided into a minimum of 24 independent pieces, ensuring that when the wearer of this invention moves, a small area of ​​fabric comes into contact with the region where the body movement is most pronounced. This allows for the identification of the fabric involved in various body movements that occur when posture begins to break down, and the presence and direction of resistance are determined by the contours of that fabric and the surrounding fabric in contact with it, namely the concave, convex, and straight lines, thereby assisting in maintaining an upright posture.

[0021] Of the fabrics constituting this invention, fabric A is positioned on the inside and upper part of the front of the garment. When viewed from the front while wearing the garment, fabric A is positioned so that it wraps around over the top of the shoulders to the shoulder blades on the back. The convex part on the upper edge of fabric A fits into the concave part of fabric H. When the human body tends to hunch forward due to fatigue while wearing the garment, it rotates the shoulder joint forward while dropping the shoulders. The concave part of fabric H is in contact with the convex part of fabric A, and fabric H tries to move upward along with the movement of the back. However, the roundness of the convex part on the upper edge of fabric A, which wraps around to the back, resists the pushing force from fabric H, making it difficult for the shoulder joint to rotate forward, and thus making it difficult for the upper body to hunch forward. Conversely, when the wearer tries to maintain an upright posture, a pushing force is generated from the convex part on the upper edge of fabric A towards the concave part on the upper edge of fabric H. In this case, the recess in fabric H offers little resistance to the pressing force from fabric A, making it easy to maintain an upright posture.

[0022] On the upper inner side of fabric A, a concave portion for receiving the convex portion of fabric L is arranged. When fatigue accumulates in maintaining a posture with the back straight during wearing, the abdomen may become relaxed and the upper body may collapse downward. When the body tries to shrink downward, fabric A also drops downward along with the relaxation of the abdomen. However, since the concave portion on the upper inner side of fabric A is fitted into the convex portion of fabric L, the rounded portion of the convex portion of fabric L resists the downward shrinkage, and an effect is exerted to make it difficult for the upper body to shrink downward. Conversely, when the wearer tries to maintain a posture with the back straight, a pushing force is generated from the convex portion of fabric L toward the concave portion of fabric A. At this time, the resistance to the pushing force from fabric L in the concave portion of fabric A is weak, and the wearer can easily maintain a posture with the back straight.

[0023] On the outer side of the right fabric A, there are three concave portions for receiving the convex portions of fabrics E, F, and G. When the upper body tries to fall to the right during wearing or when the body twists from left to right, a pushing force is generated from the concave portion of fabric A toward the convex portions of fabrics E, F, and G. At this time, resistance to the pushing force from fabric A occurs at the rounded portions of the convex portions of fabrics E, F, and G, making it difficult for the upper body to fall to the right and also exerting resistance to the twisting motion from left to right. When the posture falls to the right or twists and collapses from left to right, the left and right regions of the body do not equally contact the inner surface of the present invention. Instead, the right fabrics A, E, F, and G have increased contact with the body compared to the left fabrics A, E, F, and G. Therefore, for a person who is likely to fall to the right or for a person who is likely to have a twisting motion from left to right, on the right side of the present invention, the concave portion of fabric A can easily maintain a posture with the back straight due to the resistance generated at the rounded portions of the convex portions of fabrics E, F, and G against the pushing force that pushes the convex portions of fabrics E, F, and G.

[0024] On the outer side of the fabric A on the left, there are three concave portions for receiving the convex portions of the fabrics E, F, and G. When the upper body tends to fall to the left during wearing, or when the body is twisted from right to left, a pushing force is generated from the concave portions of the fabric A towards the convex portions of the fabrics E, F, and G. At this time, at the rounded portions of the convex portions of the fabrics E, F, and G, resistance against the pushing force from the fabric A is generated, making it difficult for the upper body to fall to the left, and also exerting resistance to the movement of twisting the body from right to left. When the posture falls to the left or twists and collapses from right to left, the left and right regions of the body do not equally contact the inner surface of the present invention. Instead, compared to the fabrics A, E, F, and G on the right side, the fabrics A, E, F, and G on the left side have an increased state of contact with the body. Therefore, for a person who is likely to fall to the left or for a person who is likely to generate an action of twisting the body from right to left, on the left side of the present invention, the concave portion of the fabric A can easily maintain a posture with the back straightened due to the resistance generated at the rounded portions of the convex portions of the fabrics E, F, and G against the pushing force that pushes the convex portions of the fabrics E, F, and G.

[0025] The fabric B is arranged below the fabric A. The lower edge of the fabric A has a concave portion for receiving the convex portion of the upper edge of the fabric B. When fatigue accumulates in maintaining a posture with the back straightened during wearing, the abdomen may be relaxed and the upper body may collapse downward. When the body tends to shrink downward, the fabric A also falls downward along with the relaxation of the abdomen. However, since the concave portion of the lower edge of the fabric A is fitted into the convex portion of the fabric B, resistance is generated at the rounded portion of the convex portion of the fabric B against the tendency to shrink downward, exerting an effect of making it difficult for the upper body to shrink downward. On the contrary, when the wearer tries to maintain a posture with the back straightened, a pushing force is generated from the convex portion of the fabric B towards the concave portion of the fabric A. At this time, the resistance to the pushing force from the fabric B in the concave portion of the fabric A is weak, and the wearer can easily maintain a posture with the back straightened.

[0026] In this invention, fabric B is positioned below fabric A. The upper edge of fabric B has a protrusion that fits into a recess on the lower edge of fabric A. When fatigue accumulates from maintaining an upright posture while wearing the garment, the abdomen may relax and the upper body may collapse downward. When the body tries to contract downward, fabric A, positioned above fabric B, also falls downward along with the relaxation of the abdomen. However, because the recess on the lower edge of fabric A is fitted into the protrusion on the upper edge of fabric B, resistance is generated at the rounded portion of the protrusion on fabric B against the downward contraction, making it difficult for the upper body to contract downward. Conversely, when the wearer tries to maintain an upright posture, a force is generated from the protrusion on fabric B toward the recess on fabric A. At this time, the recess on fabric A offers little resistance to the force from fabric B, making it easy to maintain an upright posture.

[0027] Fabrics C and D are placed at the bottom edge of fabric B. Fabric B has a recess to receive the convex part of the upper edge of fabric C, which is placed below it. Fabrics B and D are in contact in a straight line, and no effect is generated due to the difference in resistance. When fatigue accumulates from maintaining an upright posture while wearing the garment, the abdomen may relax and the upper body may collapse downward. When the body tries to contract downward, fabric B also falls downward along with the relaxation of the abdomen. However, because the recess at the bottom edge of fabric B is fitted into the convex part of the upper edge of fabric C, resistance is generated at the rounded part of the convex part of fabric C against the tendency to contract downward, thus making it difficult for the upper body to contract downward. Conversely, when the wearer tries to maintain an upright posture, a force is generated from the convex part of fabric C toward the recess in fabric B. At this time, the recess in fabric B has little resistance to the pushing force from fabric C, making it easy to maintain an upright posture.

[0028] On the outside of the right-side fabric B, the back panels I and K are positioned. The outer edge of fabric B has a recess to receive the convex portion of fabric I. Fabrics B and K are in contact in a straight line, and no effect is generated due to the difference in resistance. When the upper body tries to lean to the right or the body twists from left to right during wear, a force is generated pushing from the recess of fabric B toward the convex portion of fabric I. At this time, the rounded portion of the convex portion of fabric I generates resistance to the pushing force from fabric B, making it more difficult for the upper body to lean to the right and also providing resistance to the twisting motion of the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right regions of the body are not equally in contact with the inner surface of the present invention; rather, the right-side fabrics B and I have increased contact with the body compared to the left-side fabrics B and I. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess of fabric B on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the protrusion of fabric I against the force pressing down on the protrusion of fabric I.

[0029] On the outside of the left side fabric B, the back panels I and K are positioned. The outer edge of fabric B has a recess to receive the convex part of fabric I. Fabrics B and K are in contact in a straight line, and no effect is generated due to the difference in resistance. When the upper body tries to lean to the left or the body twists from right to left while wearing the garment, a force is generated pushing from the recess of fabric B toward the convex part of fabric I. At this time, the rounded part of the convex part of fabric I generates resistance to the pushing force from fabric B, making it difficult for the upper body to lean to the left and also providing resistance to the twisting motion of the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body are not in equal contact with the inner surface of the present invention, but rather the left side of fabric B and I has increased contact with the body compared to the right side of fabric B and I. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric B on the left side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric I against the force pressing down on the convex part of fabric I.

[0030] In this invention, fabric C is placed below fabric B. The upper edge of fabric C has a protrusion for fitting into a recess in the lower edge of fabric B. When fatigue accumulates from maintaining an upright posture while wearing the garment, the abdomen may relax and the upper body may collapse downward. When the body tries to contract downward, fabric B also falls downward along with the relaxation of the abdomen. However, because the recess in the lower edge of fabric B is fitted into the protrusion in the upper edge of fabric C, resistance is generated at the rounded portion of the protrusion in fabric C against the downward contraction, making it difficult for the upper body to contract downward. Conversely, when the wearer tries to maintain an upright posture, a force is generated from the protrusion in fabric C toward the recess in fabric B. At this time, the recess in fabric B offers little resistance to the force from fabric C, making it easy to maintain an upright posture.

[0031] Fabric D is placed on the outside of fabric C on the right side. The outer edge of fabric C has a recess to receive the protrusion of fabric D. When wearing the garment, if the upper body tries to lean to the right or the body twists from left to right, a force is generated that pushes from the recess of fabric C towards the protrusion of fabric D. At this time, the rounded portion of the protrusion of fabric D creates resistance to the pushing force from fabric C, making it more difficult for the upper body to lean to the right and also providing resistance to the twisting motion of the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right regions of the body are not in equal contact with the inner surface of the present invention, but rather the right side of fabric C and D has increased contact with the body compared to the left side of fabric C and D. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess in fabric C on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the protrusion of fabric D against the force pressing down on the protrusion of fabric D.

[0032] Fabric D is placed on the outside of fabric C on the left side. The outer edge of fabric C has a recess to receive the protrusion of fabric D. When wearing the garment, if the upper body tries to lean to the left or the body twists from right to left, a force is generated that pushes from the recess of fabric C toward the protrusion of fabric D. At this time, the rounded portion of the protrusion of fabric D creates resistance to the pushing force from fabric C, making it more difficult for the upper body to lean to the left and also providing resistance to the twisting motion of the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body are not in equal contact with the inner surface of the present invention, but rather the left side of fabric C and D has increased contact with the body compared to the right side of fabric C and D. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric C on the left side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric D against the force pressing down on the convex part of fabric D.

[0033] Of the fabrics constituting this invention, D is positioned below fabric B and outside fabric C. The upper edge of fabric D is connected to the lower edge of fabric B by a straight line, so that no effect occurs due to the difference in resistance.

[0034] Fabric C is placed inside fabric D on the right side. Fabric C has a recess on its outer edge to receive the convex part on the inside of fabric D. When the upper body tries to lean to the right or the body twists from left to right while wearing the garment, a force is generated that pushes from the recess in fabric C towards the convex part of fabric D. At this time, the rounded part of the convex part of fabric D resists the pushing force from fabric C, making it more difficult for the upper body to lean to the right and also providing resistance to the twisting motion of the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right regions of the body do not contact the inner surface of the present invention equally; rather, the right side of fabric C and D has more contact with the body than the left side of fabric C and D. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess in fabric C on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the protrusion of fabric D against the force pressing down on the protrusion of fabric D.

[0035] Fabric C is placed inside fabric D on the left side. Fabric C has a recess on its outer edge to receive the convex part on the inside of fabric D. When the upper body tries to lean to the left or the body twists from right to left while wearing the garment, a force is generated that pushes from the recess in fabric C towards the convex part of fabric D. At this time, the rounded part of the convex part of fabric D resists the pushing force from fabric C, making it more difficult for the upper body to lean to the left and also providing resistance to the twisting motion of the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body do not contact the inner surface of the present invention equally; rather, the left side of fabric C and D has more contact with the body than the right side of fabric C and D. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric C on the left side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric D against the force pressing down on the convex part of fabric D.

[0036] Of the fabrics constituting this invention, E is placed outside fabric A and above fabric B. One of the three recesses on the outside of fabric A receives the protrusion on the inside of fabric E. The lower edge of fabric E is connected to the straight portion on the upper edge of fabric B, so that no difference in resistance occurs between fabric E and fabric B. Fabric F is placed above fabric E. The lower edge of fabric F is recessed and receives the protrusion of fabric E. The outside of fabric E has a recess for receiving the protrusion of fabric I and a gentle curve for passing an arm through.

[0037] Fabric F is placed on top of fabric E. The bottom edge of fabric F is concave and receives the convex part of fabric E. When fatigue accumulates from maintaining an upright posture while wearing the garment, the abdomen may relax and the upper body may collapse downward. When the body tries to contract downward, fabric F also falls downward along with the relaxation of the abdomen. However, because the concave part of the bottom edge of fabric F is fitted into the convex part of the top edge of fabric E, resistance is generated at the rounded part of the convex part of fabric E against the downward contraction, thus making it difficult for the upper body to contract downward. Conversely, when the wearer tries to maintain an upright posture, a force is generated from the convex part of fabric E toward the concave part of fabric F. At this time, the concave part of fabric F offers little resistance to the force from fabric E, making it easier to maintain an upright posture.

[0038] Fabric A is placed inside fabric E on the right side. Fabric A has a recess on its outer edge to receive the convex part on the inside of fabric E. When the upper body tries to lean to the right or the body twists from left to right while wearing the garment, a force is generated that pushes from the recess in fabric A towards the convex part of fabric E. At this time, the rounded part of the convex part of fabric E resists the pushing force from fabric A, making it more difficult for the upper body to lean to the right and also providing resistance to the twisting motion of the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right regions of the body are not in equal contact with the inner surface of the present invention; rather, the right side of fabric A and E has increased contact with the body compared to the left side of fabric A and E. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess of fabric A on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex portion of fabric E against the force pressing down on the convex portion of fabric E.

[0039] Fabric I is placed on the outside of fabric E on the right side. Fabric E has a recess on its outer edge to receive the protrusion of fabric I. When the upper body tries to lean to the right or the body twists from left to right while wearing the garment, a force is generated that pushes from the recess of fabric E toward the protrusion of fabric I. At this time, the rounded portion of the protrusion of fabric I creates resistance to the pushing force from fabric E, making it more difficult for the upper body to lean to the right and also providing resistance to twisting the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right regions of the body are not in equal contact with the inner surface of the present invention; rather, the right side of fabric E and fabric I has more contact with the body than the left side of fabric E and fabric I. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess of fabric E on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex portion of fabric I against the force pressing down on the convex portion of fabric I.

[0040] Fabric A is placed inside fabric E on the left side. Fabric A has a recess on its outer edge to receive the convex part on the inside of fabric E. When the upper body tries to lean to the left or the body twists from right to left while wearing the garment, a force is generated that pushes from the recess in fabric A towards the convex part of fabric E. At this time, the rounded part of the convex part of fabric E resists the pushing force from fabric A, making it more difficult for the upper body to lean to the left and also providing resistance to the twisting motion of the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body are not in equal contact with the inner surface of the present invention; rather, the left side of fabric A and E has increased contact with the body compared to the right side of fabric A and E. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric A on the left side of this invention can easily maintain an upright posture due to the resistance generated by the rounded part of the convex part of fabric E against the force pressing down on the convex part of fabric E.

[0041] Fabric I is placed on the outside of fabric E on the left side. Fabric E has a recess on its outer edge to receive the protrusion of fabric I. When the upper body tries to lean to the left or the body twists from right to left while wearing the garment, a force is generated that pushes from the recess of fabric E toward the protrusion of fabric I. At this time, the rounded portion of the protrusion of fabric I creates resistance to the pushing force from fabric E, making it more difficult for the upper body to lean to the left and also providing resistance to the twisting motion of the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body are not in equal contact with the inner surface of the present invention, but rather the left side of fabric E and fabric I has more contact with the body than the right side of fabric E and fabric I. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric E on the left side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric I against the force pressing down on the convex part of fabric I.

[0042] Of the fabrics constituting this invention, F is positioned on the outside of fabric A and above fabric E. One of the three recesses on the outside of fabric A receives the protrusion on the inside of fabric F. Fabric G is positioned above fabric F. The outside of fabric F has a gentle curve for inserting an arm.

[0043] Fabric E is placed below fabric F. The bottom edge of fabric F is concave and receives the convex part of fabric E. When fatigue accumulates from maintaining an upright posture while wearing the garment, the abdomen may relax and the upper body may collapse downward. When the body tries to contract downward, fabric F also falls downward along with the relaxation of the abdomen. However, because the concave part of the bottom edge of fabric F is fitted into the convex part of the top edge of fabric E, the rounded part of the convex part of fabric E resists the downward contraction, making it difficult for the upper body to contract downward. Conversely, when the wearer tries to maintain an upright posture, a force is generated from the convex part of fabric E toward the concave part of fabric F. At this time, the concave part of fabric F offers little resistance to the force from fabric E, making it easy to maintain an upright posture.

[0044] Fabric G is placed on top of fabric F. The top edge of fabric F is convex and fits into the concave part of fabric G. When the human body is fatigued while wearing the garment, it tends to hunch forward, rotating the shoulder joint forward while dropping the shoulders. The concave part of fabric G is in contact with the convex part of fabric F, and fabric G tries to move upward along with the movement of the back. However, the roundness of the convex part of fabric F resists the pushing force from the concave part of fabric G, making it difficult for the shoulder joint to rotate forward, and thus making it difficult for the upper body to hunch forward. Conversely, when the wearer tries to maintain an upright posture, a pushing force is generated from the convex part of the top edge of fabric F toward the concave part of the top edge of fabric G. In this case, the concave part of fabric G has little resistance to the pushing force from fabric F, making it easy to maintain an upright posture.

[0045] Fabric A is placed inside fabric F on the right side. Fabric A has a recess on its outer edge to receive the convex part on the inside of fabric F. When the upper body tries to lean to the right or the body twists from left to right while wearing the garment, a force is generated that pushes from the recess in fabric A towards the convex part of fabric F. At this time, the rounded part of the convex part of fabric F resists the pushing force from fabric A, making it more difficult for the upper body to lean to the right and also providing resistance to the twisting motion of the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right regions of the body are not in equal contact with the inner surface of the present invention; rather, the right side of fabric A and F has increased contact with the body compared to the left side of fabric A and F. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess in fabric A on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the protrusion of fabric F against the force pressing down on the protrusion of fabric F.

[0046] Fabric A is placed inside fabric F on the left side. Fabric A has a recess on its outer edge to receive the convex part on the inside of fabric F. When the upper body tries to lean to the left or the body twists from right to left while wearing the garment, a force is generated that pushes from the recess in fabric A towards the convex part of fabric F. At this time, the rounded part of the convex part of fabric F resists the pushing force from fabric A, making it more difficult for the upper body to lean to the left and also providing resistance to the twisting motion of the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body are not in equal contact with the inner surface of the present invention; rather, the left side of fabric A and F has increased contact with the body compared to the right side of fabric A and F. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric A on the left side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric F against the force pressing down on the convex part of fabric F.

[0047] Of the fabrics constituting this invention, G is positioned on the upper outer surface of fabric A, on the upper surface of fabric F, on the upper outer surface of fabric H, and on the upper surface of fabric I. The upper inner surface of fabric G is convex and fits into the recess on the upper outer surface of fabric A. The upper outer surface of fabric G is recessed and receives the convex part of fabric F. The lower inner surface of fabric G is convex and fits into the recess of fabric H. The lower part of fabric G is straight and touches fabric I in a straight line, so no resistance is exerted between fabric G and fabric I. The outer surface of fabric G has a gentle curve for passing an arm through.

[0048] Fabric F is placed on top of fabric G. The upper edge of fabric F has a convex part that fits into the concave part of fabric G. When the human body tends to hunch forward due to fatigue while wearing the garment, it rotates the shoulder joint forward while dropping the shoulders. The convex part of fabric F is in contact with the concave part of fabric G, and fabric G tries to move upward along with the movement of the back. However, the roundness of the convex part of fabric F resists the pushing force from the concave part of fabric G, making it difficult for the shoulder joint to rotate forward, and thus making it difficult for the upper body to hunch forward. Conversely, when the wearer tries to maintain an upright posture, a pushing force is generated from the convex part of the upper edge of fabric F toward the concave part of the upper edge of fabric G. At this time, the concave part of fabric G has little resistance to the pushing force from fabric F, and it is easy to maintain an upright posture.

[0049] Fabric H is placed on the lower inner side of fabric G. The upper outer side of fabric H is concave and fits into the convex part of fabric G. When the human body tends to hunch forward due to fatigue while wearing the garment, it rotates the shoulder joint forward while dropping the shoulders. The concave part of fabric H is in contact with the convex part of fabric G, and fabric H tries to move upward along with the movement of the back. However, the roundness of the convex part of fabric G resists the pushing force from fabric H, making it difficult for the shoulder joint to rotate forward, and thus making it difficult for the upper body to hunch forward. Conversely, when the wearer tries to maintain an upright posture, a pushing force is generated from the convex part on the lower inner side of fabric G toward the concave part on the upper outer side of fabric H. At this time, the concave part of fabric H has little resistance to the pushing force from the convex part of fabric G, making it easy to maintain an upright posture. Furthermore, because fabric G is on the outside and fabric H is on the inside, when the wearer tries to maintain an upright posture, it creates an effect where the wearer's shoulders tend to open outwards to the left and right.

[0050] The upper inner surface of the right-side fabric G is convex and fits into the concave part of fabric A. When wearing the garment, if the upper body tries to lean to the right or the body twists from left to right, a force is generated pushing from the concave part of fabric A towards the convex part of fabric G. At this time, the rounded part of the convex part of fabric G resists the pushing force from fabric A, making it more difficult for the upper body to lean to the right and also providing resistance to twisting the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right sides of the body do not evenly contact the inner surface of the present invention; rather, the right-side fabric A and G have more contact with the body than the left-side fabric A and G. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recess of fabric A on the right side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the protrusion of fabric G against the force pressing down on the protrusion of fabric G.

[0051] The upper inner surface of the left side of fabric G is convex, which fits into the concave part of fabric A. When wearing the garment, if the upper body tries to lean to the left or the body twists from right to left, a force is generated pushing from the concave part of fabric A towards the convex part of fabric G. At this time, the rounded part of the convex part of fabric G resists the pushing force from fabric A, making it more difficult for the upper body to lean to the left and also providing resistance to twisting the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right sides of the body do not contact the inner surface of the present invention equally; rather, the left side of fabric A and G has more contact with the body than the right side of fabric A and G. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave part of fabric A on the left side of this invention allows them to easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric G against the force pressing down on the convex part of fabric G.

[0052] Of the fabrics constituting this invention, H is positioned on the upper part of fabric A, the lower inner part of fabric G, the inner part of fabric I, the upper part of fabric J, the outer part of fabric L, and the outer part of fabric M. Fabric L and fabric M are in contact in a straight line. Fabric H does not exert any resistant effect between fabric L and fabric M.

[0053] Fabric A is placed on the upper part of fabric H, and fabric G is placed on the upper outer part of fabric H. The upper part of fabric H is concave and fits into the convex part of fabric A. The upper outer part of fabric H is concave and fits into the convex part of fabric G. When the human body tends to hunch forward due to fatigue while wearing the garment, it rotates the shoulder joint forward while dropping the shoulders. The convex parts of fabric A and fabric G are in contact with the corresponding concave parts of fabric H, and fabric H tries to move upward along with the movement of the back. However, the roundness of the convex parts of fabric A and fabric G resists the pushing force from the concave part of fabric H, making it difficult for the shoulder joint to rotate forward, and thus making it difficult for the upper body to hunch forward. Conversely, when the wearer tries to maintain an upright posture, a pushing force is generated from the convex parts of fabric A and fabric G toward the concave part of fabric H. In this case, the concave portion of fabric H offers less resistance to the pressing force from the convex portions of fabrics A and G, making it easier to maintain an upright posture. Additionally, the presence of fabric G on the outside and fabric H on the inside makes it easier for the wearer to adopt a posture that straightens the spine and expands the rib cage by pulling the shoulders back.

[0054] The outer surface of fabric H has a convex part that fits into the concave part of fabric I. When wearing the garment and bending the body forward while twisting from right to left, the convex part of fabric H on the right side of the body presses against the concave part of fabric I, thus reducing the resistance in the concave part of fabric I. On the other hand, in the relationship between fabric H and fabric I on the left side of the body, the concave part of fabric I presses against the convex part of fabric H, creating resistance in the rounded shape of the convex part of fabric H on the left side. This reduces the movement of the body twisting and collapsing from right to left.

[0055] The outer surface of fabric H has a convex part that fits into the concave part of fabric I. When wearing the garment and bending the body forward while twisting from left to right, the convex part of fabric H on the left side of the body presses against the concave part of fabric I, thus reducing the resistance in the concave part of fabric I. On the other hand, in the relationship between fabric H and fabric I on the right side of the body, the concave part of fabric I presses against the convex part of fabric H, creating resistance in the rounded shape of the convex part of fabric H on the right side. This reduces the movement of the body twisting and collapsing from left to right.

[0056] Fabric J is placed below fabric H. The lower part of fabric H has a convex shape, which fits into the concave part at the top of fabric J. When the wearer's body tends to hunch forward due to fatigue while wearing the garment, fabric J tries to move upward along with the movement of the back. However, the rounded shape of the convex part of fabric H resists the pushing force from the concave part of fabric J, making it difficult for the upper body to hunch forward. Conversely, when the wearer tries to maintain an upright posture, a pushing force is generated from the convex part of fabric H towards the concave part of fabric J. At this time, the concave part of fabric J offers little resistance to the pushing force from fabric H, making it easier to maintain an upright posture.

[0057] Of the fabrics constituting this invention, fabric I is positioned below fabric G, outside fabric H, above and outside fabric J, above fabric K, outside fabric B, and outside fabric E. Since fabric I and fabric G are in contact in a straight line, no resistance is generated.

[0058] The inside of fabric I is concave and receives the convex part of fabric H. When wearing the garment and bending the body forward while twisting from right to left, the convex part of fabric H on the right side of the body and the concave part of fabric I are reduced because the convex part of fabric H pushes against the concave part of fabric I. On the other hand, in the relationship between fabric H and fabric I on the left side of the body, the concave part of fabric I pushes against the convex part of fabric H, creating resistance in the rounded shape of the convex part of fabric H on the left side. This reduces the movement of the body twisting and collapsing from right to left.

[0059] The inside of fabric I is concave and receives the convex part of fabric H. When wearing the garment and bending the body forward while twisting from left to right, the convex part of fabric H on the left side of the body and the concave part of fabric I are reduced because the convex part of fabric H pushes against the concave part of fabric I. On the other hand, in the relationship between fabric H and fabric I on the right side of the body, the concave part of fabric I pushes against the convex part of fabric H, creating resistance in the rounded shape of the convex part of fabric H on the right side. This reduces the movement of the body twisting and collapsing from left to right.

[0060] The outer surface of fabric I on the right side is convex, which fits into the concave parts of fabrics B and E. When wearing the garment, if the upper body tries to lean to the right or the body twists from left to right, a pushing force is generated from the concave parts of fabrics B and E toward the convex part of fabric I. At this time, the rounded portion of the convex part of fabric I resists the pushing force from the concave parts of fabrics B and E, making it more difficult for the upper body to lean to the right and also providing resistance to twisting the body from left to right. When the posture leans to the right or twists and collapses from left to right, the left and right sides of the body do not contact the inner surface of the present invention equally; rather, the right side of fabrics I, B, and E has increased contact with the body compared to the left side of fabrics I, B, and E. Therefore, for people whose bodies tend to lean to the right, or whose bodies tend to twist from left to right, the recesses of fabric B and fabric E on the right side of this invention allow them to easily maintain an upright posture by resisting the force pressing against the protrusion of fabric I with the resistance generated by the rounded portion of the protrusion of fabric I.

[0061] The lower inner surface of fabric I on the right side is concave, receiving the convex part of fabric J. When the body is twisted from left to right while wearing the garment, a force is generated pushing from the concave part of fabric I toward the convex part of fabric J. At this time, the rounded portion of the convex part of fabric J resists the pushing force from the concave part of fabric I, providing resistance to the twisting motion of the body from left to right.

[0062] The outer surface of fabric I on the left side is convex, which fits into the concave parts of fabrics B and E. When wearing the garment, if the upper body tries to lean to the left or the body twists from right to left, a force is generated that pushes from the concave parts of fabrics B and E towards the convex part of fabric I. At this time, the rounded portion of the convex part of fabric I creates resistance to the pushing force from the concave parts of fabrics B and E, making it more difficult for the upper body to lean to the left and also providing resistance to twisting the body from right to left. When the posture leans to the left or twists and collapses from right to left, the left and right regions of the body are not in equal contact with the inner surface of the present invention; rather, the left side of fabrics I, B, and E has increased contact with the body compared to the right side of fabrics I, B, and E. Therefore, for people whose bodies tend to lean to the left, or whose bodies tend to twist from right to left, the concave parts of fabric B and fabric E on the left side of this invention can easily maintain an upright posture due to the resistance generated by the rounded portion of the convex part of fabric I against the force pressing down on the convex part of fabric I.

[0063] The lower inner surface of fabric I on the left side is concave, receiving the convex part of fabric J. When the body is twisted from right to left while wearing the garment, a force is generated pushing from the concave part of fabric I toward the convex part of fabric J. At this time, the rounded portion of the convex part of fabric J creates resistance against the pushing force from the concave part of fabric I, providing resistance to the twisting motion of the body from right to left.

[0064] The lower part of fabric I is concave and receives the convex part of fabric K. People who wear thick, wide disposable diapers in their groin area tend to have a posterior pelvic tilt. This posterior pelvic tilt causes the upper body to lean further and further backward. At this time, the concave part of fabric I presses against the convex part of fabric K, but the roundness of the convex part of fabric K creates resistance, mitigating the excessive backward leaning of the upper body.

[0065] Of the fabrics constituting the present invention, J is positioned at the bottom of fabric H, the inside of the bottom of fabric I, the inside of fabric K, and the outside of fabric M. The insides of fabric J are in contact with each other on the left and right sides, but the edges where the left and right fabrics J meet are straight lines, so no resistance is generated between the left and right fabrics J.

[0066] The upper part of fabric J is concave and receives the convex part of fabric H. When you get tired of maintaining an upright posture, your body tends to lean forward. When your body tries to lean forward, the concave part of fabric J presses against the convex part of fabric H. The roundness of the convex part of fabric H creates resistance, making it difficult to lean forward.

[0067] The upper outer part of fabric J on the right side is convex, which fits into the concave part of fabric I. When the body is twisted from left to right while wearing the garment, a force is generated pushing from the concave part of fabric I towards the convex part of fabric J. At this time, the rounded part of the convex part of fabric J creates resistance to the pushing force from the concave part of fabric I, providing resistance to the twisting motion of the body from left to right.

[0068] The outer surface of fabric J on the right side is convex, which fits into the concave part of fabric K. When the wearer's abdominal strength is weak and their posture collapses, causing them to twist their body from left to right and fall forward to the left, the concave part of fabric K on the right side pushes against the convex part of fabric J. At this time, resistance is generated by the roundness of the convex part of fabric J, reducing the force that would cause the body to fall forward to the left.

[0069] The upper outer part of fabric J on the left side is convex, which fits into the concave part of fabric I. When the body is twisted from right to left while wearing the garment, a force is generated pushing from the concave part of fabric I towards the convex part of fabric J. At this time, the rounded part of the convex part of fabric J creates resistance to the pushing force from the concave part of fabric I, providing resistance to the twisting motion of the body from right to left.

[0070] The outer surface of fabric J on the left side is convex, which fits into the concave part of fabric K. When the wearer's abdominal strength is weak and their posture collapses, causing them to twist their body from right to left and fall forward to the right, the concave part of fabric K on the left side pushes against the convex part of fabric J. At this time, resistance is generated by the roundness of the convex part of fabric J, reducing the force that would cause the body to fall forward to the right.

[0071] Of the fabrics constituting this invention, K is positioned below fabric I and outside fabric J. The upper part of fabric K is convex and fits into the recess of fabric I. The inner upper part of fabric K is recessed and receives the convex part of fabric J. The outer surface of fabric K is straight and connects to the outer surfaces of fabrics B and D, and no resistance is generated between fabrics K, B, and D.

[0072] The upper part of fabric K is convex and fits into the concave part of fabric I. People who wear thick, wide disposable diapers in their groin area tend to have a posterior pelvic tilt. This posterior pelvic tilt causes the upper body to lean further and further backward. At this time, the concave part of fabric I presses against the convex part of fabric K, but the rounded shape of the convex part of fabric K creates resistance, mitigating the excessive backward leaning of the upper body.

[0073] The inside of the right-side fabric K is concave, receiving the convex part of fabric J. When the wearer's abdominal strength is weak and their posture collapses, causing them to twist their body from left to right and fall forward to the left, the concave part of the right-side fabric K acts to push against the convex part of fabric J. At this time, resistance is generated by the curvature of the convex part of fabric J, reducing the force that would cause the body to fall forward to the left.

[0074] The inside of the left side of fabric K is concave, receiving the convex part of fabric J. When the wearer's abdominal strength is weak and their posture collapses, causing them to twist their body from right to left and fall forward to the right, the concave part of fabric K on the left side acts to push against the convex part of fabric J. At this time, resistance is generated by the curvature of the convex part of fabric J, reducing the force that would cause the body to fall forward to the right.

[0075] Of the fabrics constituting this invention, L is positioned at the spine when worn. Fabric A is placed on the upper outer side, fabric H on the outer side, and fabric M on the lower side. Since fabrics L and H are connected in a straight line, no resistance is generated.

[0076] Fabric L has a protrusion on its upper outer side, which fits into a recess in fabric A. When wearing the garment, if the wearer's posture is disrupted, such as twisting the body from right to left and leaning forward to the right, the recess on the left side of fabric A pushes against the protrusion on the upper outer left side of fabric L. At this time, resistance is generated in the rounded shape of the protrusion on the upper outer left side of fabric L, which reduces the tendency for the body to twist from right to left and lean forward to the right.

[0077] Fabric L has a protrusion on its upper outer side, which fits into a recess in fabric A. When wearing the garment, if the wearer's posture is disrupted, such as twisting the body from left to right and leaning forward to the left, the recess on the right side of fabric A pushes against the protrusion on the upper outer right side of fabric L. At this time, resistance is generated in the rounded shape of the protrusion on the upper outer right side of fabric L, which reduces the tendency for the body to twist from left to right and lean forward to the left.

[0078] The lower part of fabric L is concave and receives the convex part of fabric M. People who wear thick, wide disposable diapers in their groin area tend to have a posterior pelvic tilt. This posterior pelvic tilt causes the upper body to lean further and further backward. At this time, the concave part of fabric L presses against the convex part of fabric M, but the roundness of the convex part of fabric M creates resistance, mitigating the excessive backward leaning of the upper body.

[0079] Of the fabrics constituting this invention, fabric M is positioned at the spine when worn. Fabric L is placed at the top, fabric H is placed on the left and right outer sides, and fabric J is placed on the left and right lower outer sides. Since fabrics M and H are in contact in a straight line, no resistance is generated.

[0080] The top of fabric M has a convex shape that fits into the concave shape of fabric L. People who wear thick, wide disposable diapers in their groin area tend to have a posterior pelvic tilt. This posterior pelvic tilt causes the upper body to lean further and further backward. At this time, the concave shape of fabric L presses against the convex shape of fabric M, but the rounded shape of the convex shape of fabric M creates resistance, mitigating the excessive backward leaning of the upper body.

[0081] The lower outer part of fabric M is concave, which receives the convex part of fabric J. People who wear thick, wide disposable diapers in their groin area tend to have a posterior pelvic tilt. This posterior pelvic tilt causes the upper body to lean further and further backward. At this time, the concave part of fabric M presses against the convex part of fabric J, but the roundness of the convex part of fabric J creates resistance, mitigating the excessive backward leaning of the upper body.

[0082] The fabrics constituting this invention can be joined together by sewing them with thread, just like in ordinary sewing. [Explanation of Symbols]
