Mode for Carrying Out the Invention

[0009] Hereinafter, the undergarment X according to each embodiment of the present invention will be described with reference to the drawings. The description will detail the configuration of the embodiment, the method of implementation, and other examples in this order. Note that the embodiments shown below are examples of the present invention, and the present invention is not limited to the following embodiments. Also, "approximate" in the application documents means that chamfering or rounding is applied to the subsequent shape, and that the elements constituting the shape are deformed or the length is changed within a range that does not impede the purpose of the configuration. Further, stretchability is the property of stretching and contracting. The lower the stretchability, the greater the force required to stretch, and the greater the force (kickback) to return when stretched.

[0010] ≪First Embodiment≫ The present invention includes a stretchable body 1. The body 1 has a front body 11 that covers the front half of the user and a rear body 12 that is continuous with the front body 11 and covers the rear half of the user. A stretch control unit 2 for controlling the degree of stretch of the body 1 is disposed at a predetermined position. A ring-shaped arm outlet 13 for the user to extend the arm is provided between the front body 11 and the rear body 12. The arm outlet 13 includes a front arm outlet 131 located on the front body 11 side and a rear arm outlet 132 located on the rear body 12 side. The rear arm outlet 132 is provided closer to the midline than the front arm outlet 131. The stretch control unit 2 is an undergarment including a back stretch portion 21 at least partially disposed along the rear arm outlet 132. Also, the rear arm outlet 132 is provided so as to overlap the scapula of the user when worn, and the stretch control unit 2 is an undergarment including a back stretch portion 21 at least partially disposed along the rear arm outlet 132.

[0011] The present invention includes a stretchable fabric material body 1 that covers the upper body of the user and a stretch control unit 2 disposed at a predetermined position on the body 1 to control the degree of stretch at that position. The portion of the body 1 where the stretch control unit 2 is provided has lower stretchability than the portion where it is not provided, and is a region with cross-hatching or a thick line portion in the drawing.

[0012] The body main part 1 includes a stretchable front body part 11 that covers the user's upper front body, a stretchable rear body part 12 that covers the user's lower rear body, an arm outlet part 13 provided from the front body part 11 to the rear body part 12 for the user to extend their arms, a neck outlet part 14 for the user to extend their neck, and a shoulder connection part 15 that connects the front body part 11 and the rear body part 12 on the neck side of the body main part 1 and is positioned on the user's shoulders during use.

[0013] The front body part 11 and the rear body part 12 are parts made of stretchable fabric, and are connected to the other body main part in the regions formed between the side boundaries and between the arm outlet part 13 and the neck outlet part 14 respectively, so as to cover the entire body of the user like a running shirt. A stretch control part 2 may be used for these connected parts to prevent this part from being easily stretched unintentionally. Also, the body-side ends of the front body part 11 and the rear body part 12 are made to have reduced stretchability by being folded back. Here, the materials of the front body part 11 and the rear body part 12 are stretchable materials blended with polyurethane, which improves the mobility of the user's arms.

[0014] The arm outlet part 13 is an annular part provided so that the user can extend their arms, and is provided symmetrically on both sides of the front body part 11 and the rear body part 12 respectively. The arm outlet part 13 further includes a front arm outlet part 131 provided on the front body part 11 side, a rear arm outlet part 132 provided on the rear body part 12 side, and a part that connects the front arm outlet part 131 and the rear arm outlet part 132 on the body side of the body main part 1, which is the side arm outlet part 133 positioned on the user's side during use.

[0015] The neck outlet part 14 is an annular part provided so that the user can extend their neck, and is provided to face the opening around the body. The edges of the arm outlet part 13 and the neck outlet part 14 are preferably reinforced with a reinforcing member such as rubber to prevent fraying. The neck outlet part 14 is bent so as not to overlap with the user's collarbone, facilitating the arm-raising movement.

[0016] The forearm extending portion 131 is the portion of the arm extending portion 13 on the front body 11 from the shoulder connection portion 15 to the side arm extending portion 133, occupies about 50% to 75% of the arm extending portion 13 on the front body 11, and surrounds the upper part of the user's side when viewed from the front.

[0017] The upper arm extending portion 132 is the portion of the arm extending portion 13 on the back body 12 from the shoulder connection portion 15 to the side arm extending portion 133, occupies about 60% to 85% of the arm extending portion 13 on the back body 12, and surrounds the upper part of the user's side when viewed from the back.

[0018] The side arm extending portion 133 occupies a region of 20% to 40% of the entire arm extending portion and surrounds the lower part of the user's side. The side arm extending portion 133 is provided so as to overlap with the front body 11 and the back body 12, but the area located on the back body 12 is larger, making it easier to appropriately stretch around the scapula.

[0019] When viewed from the back, the arm extending portion 13 or the upper arm extending portion 132 provided on the back body 12 is bent more in the midline direction than the arm extending portion 13 or the forearm extending portion 131 provided on the front body 11. This does not interfere with the movement of the scapula, makes it easier to naturally open the shoulders, and enables the user to move the shoulder area more easily. This bending is preferably along the edge of the user's scapula, which prevents large interference between the scapula and the arm extending portion 13 during wearing and suppresses the position of the scapula from dropping below a certain level. Particularly preferably, a part of the arm extending portion 13 is provided so as to ride on the head side of the scapular spine (covering from the inner edge to the upper edge of the scapular spine).

[0020] The stretch control portion 2 is the portion where the fabric materials overlap as shown in the drawing in the body 1, and in the embodiment, it is mainly the portion where the stretch member is provided by overlapping the back body 12. The stretchability of this stretch member is preferably substantially the same as or lower than the stretchability of the body 1. This suppresses the elongation at a predetermined position of the body 1, and particularly supports contraction when the lower fibers of the subscapularis muscle are elongated, thereby supporting the user's posture.

[0021] The telescopic control unit 2 includes a back telescopic part 21 disposed on the back body 12, a side telescopic part 22 disposed at the side position, and a spine telescopic part 23 disposed along the center line of the back body 12. By the telescopic actions of these parts, the posture of the user is made closer to an ideal posture.

[0022] In the embodiment, the back telescopic part 21 includes a back telescopic part main body 210 which is a cloth material provided from near the upper end to the lower end of the back body 12, a neck side boundary 211 that connects the back telescopic part main body 210 to the body 1 at the neck side, and a side surface boundary 212 that connects the back telescopic part main body 210 to the body 1 at the side part. Further, the back telescopic part 21 is disposed along the boundary of the rear arm extending part 132 and the spine telescopic part 23 and is connected to the lower end around the torso. In this way, in the part corresponding to the torso of the body 1, the range where the telescopic control unit 2 is provided in the circumferential direction of the torso is smaller than the part hitting the chest, making it easier for the user to breathe without constricting the abdomen. In particular, the back telescopic part 21 supports the contraction of the lower fibers of the trapezius muscle in addition to the above effect, making it easier to expand the rib cage and facilitating the user's breathing.

[0023] In the back telescopic part main body 210, a belt-like cloth material (power net) with lower stretchability than the body 1 is disposed so as to overlap the body 1. In the embodiment, the cloth material is disposed on the back surface. This enhances the elasticity of the back telescopic part 21 and makes it less likely to deform at this part. Also, it is provided symmetrically about the spine telescopic part 23.

[0024] The neck side boundary 211 is provided at the rear arm extending part 132 so as to connect from a position several centimeters away from the shoulder connection part 15 to the middle of the spine telescopic part 23. This part particularly acts to hang on the scapula and pull towards the waist side when the user raises the hand, thus supporting the lower fibers of the trapezius muscle. The distance from the neck side boundary 211 to the neck extending part 14 is provided to be increasingly spaced towards the spine telescopic part 23, enhancing the stretchability around the neck to prevent tightening during wearing and improving comfort so that the movement of the middle fibers of the trapezius muscle is not hindered. In the embodiment, stitches are further provided in a zigzag pattern along the neck-side boundary 211, and the stitches themselves are provided so as to control expansion and contraction, thereby further enhancing the kickback in this portion.

[0025] The side boundary 212 is a connecting portion that extends substantially vertically from the boundary between the rear arm extension portion 132 and the side arm extension portion 133 to the body-side end, and is provided substantially parallel to the spinal expansion and contraction portion 23. Thereby, while supporting the spinal expansion and contraction portion 23, it becomes possible to support the contraction of the muscle from the lowermost end of the lower fibers of the trapezius muscle. Note that, similar to the neck-side boundary 211, stitches may be provided in a zigzag pattern along the side boundary 212.

[0026] Further, the back expansion and contraction portion main body 210 is connected to the rear arm extension portion 132. When the posture deviates from the ideal state and the lower fibers of the trapezius muscle are extended, a force is applied in the direction of contracting this, and by setting the contraction fixing point to the arm extension portion 13, the contraction action can be made to act appropriately and strongly.

[0027] Further, the boundary of the back expansion and contraction portion main body 210 is connected along the boundary of the spinal expansion and contraction portion 23, so that the spinal expansion and contraction portion 23 can be supported in the same manner as the side boundary 212.

[0028] The side expansion and contraction portion 22 is a portion with lower elasticity compared to the body 1 provided along the side arm extension portion 133, and is provided with a belt-like cloth material (power net) that overlaps with the same body 1 as the back expansion and contraction portion main body 210. In the embodiment, the side expansion and contraction portion 22 is provided so as to smoothly connect the end of the side arm extension portion 133 on the front body 11 side from a position about 3 cm to 5 cm away from the rear arm extension portion 132 on the side boundary 212 toward the body side.

[0029] The side expansion and contraction portion 22 supports the posture by contracting in the direction of narrowing the scapula when the scapula is in a state of being opened too much (for example, when the shoulder is shrugged). The side expansion and contraction portion 22 includes a part of the front body 11, thereby further enhancing this effect. In addition, the side expansion / contraction part 22 is configured to distribute the contraction action of the back expansion / contraction part main body 210 not only to the rear arm extending part 132 but also to the side arm extending part 133, thereby preventing force from being applied to a specific position during contraction and enhancing the usability.

[0030] The spine expansion / contraction part 23 is a non-elastic part provided on the center line of the back body 12, and is provided by connecting an elastic tape material (band material) from the neck extending part 14 to the lower end of the back body 12. In addition, zigzag stitches may be provided on the spine expansion / contraction part 23. The spine expansion / contraction part 23 is at least less elastic than the back expansion / contraction part 21, and preferably is the least elastic in the expansion / contraction control part 2, thereby supporting the erector spinae muscles or multifidus muscles. More specifically, when the user slumps, the spine expansion / contraction part 23 contracts and applies a force to the spine in the direction of extending the back muscles to support the posture. In addition to the contraction support of the lower fibers of the trapezius muscle by the back expansion / contraction part 21, the present invention can appropriately maintain the curvature of the spine, prevent and reduce spinal stenosis and intervertebral disc herniation by the support of the multifidus muscle and the like by the spine expansion / contraction part 23. In addition, the highly elastic and strong spine expansion / contraction part 23 is provided so as to be connected to the back expansion / contraction parts 21 located on both sides, so that even if the back expansion / contraction part 21 is deformed asymmetrically, the central axis is less likely to shift and the posture support performance is improved.

[0031] 《Usage method》 As shown in FIG. 3, the user wears the undergarment X by putting the arms out from the arm extending parts 13 and the neck out from the neck extending part 14. At this time, since a part of the rear arm extending part 132 and the side arm extending part 133 is located along the outer edge of the scapula of the user, the movement of the user's shoulder is not hindered. In addition, when the user slumps and the lower fibers of the trapezius muscle extend, the back expansion / contraction part 21 acts in the direction of contracting this to promote the maintenance of the posture, and when the user's scapula opens, the side expansion / contraction part 22 contracts in the midline direction to promote the maintenance of the posture. By providing these members adjacent to each other, the contraction of the lower fibers of the trapezius muscle can be appropriately supported.

[0032] 《Second embodiment》 Hereinafter, for the same configurations as those in the first embodiment according to the second embodiment of the present invention, the description will be omitted by using the same reference numerals. In the present embodiment, the body 1 is in a form particularly suitable for a female body and is a so-called bra top having a chest holding portion B that holds the user's chest. Further, FIG. 5 is a schematic front view of the body 1 cut open at the side boundaries of the shoulder connection portion 15, the front body 11, and the back body 12, and FIG. 6 is a schematic back view of the same body 1. FIG. 7 is a schematic view in a worn state, and the broken line shows the chest holding portion B located below the body 1.

[0033] The present invention includes a body 1 and a stretch control portion 2 disposed at a predetermined position above the body 1. The body 1 includes a front body 11, a back body 12, an arm outlet portion 13, a neck outlet portion 14, and a shoulder connection portion 15. Here, the body 1 has a chest holding portion B disposed so as to overlap the back surfaces of the front body 11 and the back body 12. Further, the stretch control portion 2 is disposed on the chest holding portion B on the back body 12 and includes a back stretch portion 21, a side stretch portion 22, a spine stretch portion 23, and a side auxiliary stretch portion 24 disposed adjacent to a cup portion described later. By the stretching actions of these, the user's posture is brought closer to an ideal posture.

[0034] The chest holding portion B is mainly connected on the back side of the body 1 and has two portions, a portion provided as a part of the front body 11 and a portion provided as a part of the back body 12, and a part of each is arranged so as to overlap the outer portion 1E of the body 1. Specifically, the outer portion 1E of the front body 11 is connected at the edge of the shoulder connection portion 15 of the chest holding portion B, and the portion closer to the waist side than that is the area where the outer portion 1E covers the chest holding portion B. Also, the outer portion 1E of the back body 12 is provided on the shoulder side of the underarm opening portion 133, both ends are connected to the rear arm opening portion 132, and it has an overlapping portion P so as to span the rear arm opening portions 132 on both sides. In the area closer to the waist side than the overlapping portion P, the outer portion 1E covers the entire chest holding portion B. On the other hand, in the area closer to the shoulder side than the overlapping portion P, the chest holding portion B is provided so as to be exposed. Also, the overlapping portion P is provided spaced apart from the chest holding portion B on its surface, thereby preventing the influence of the stretchability of the stretch control portion 2 by the overlapping portion P. More specifically, the outer portion 1E is connected so as to hang from the arm opening portion 13 (excluding the front arm opening portion 131) and the neck opening portion 14, so as not to interfere with the stretch performance of the stretch control portion 2 in the chest holding portion B. In addition, in FIGS. 5 and 6, the outer portion 1E of the body 1 is indicated by hatching.

[0035] The chest holding portion B has, at the lower end of the chest holding portion B, an enclosing portion B1 that holds around the user's chest, and a cup portion B2 for holding a predetermined shape adapted to the breasts. Also, it includes the arm opening portion 13, and on the back body 12 side, a back stretch portion 21 and a spine stretch portion 23 are provided, and a side stretch portion 22 is provided along the underarm opening portion 133.

[0036] The enclosing portion B1 is a highly stretchable member provided in a band shape and is provided so as to go around the user's chest. By holding around the chest in this way, it becomes a fixed point when stretching, and the stretch performance by the stretch control portion 2 can be improved. Also, since it is provided with a member having high stretchability such as rubber, the feeling of fit to the body is enhanced.

[0037] The cup portion B2 is provided adjacent to the enclosing portion B1 and is made of a thicker material than the surrounding members so as to protect the breasts. Thereby, the fit performance to the user's body can be improved.

[0038] The telescopic control unit 2 is provided on the chest holding part B located on the side that comes into contact with the user's body during use, thereby improving the telescopic performance. Here, the telescopic property of the spinal telescopic part 23 is the lowest, the back telescopic part 21 is the next lowest, and the side telescopic part 22 and the side auxiliary telescopic part 24 are provided so that their telescopic properties are the next lowest. In the embodiment, the back telescopic part 21 is provided by overlapping a power net that is less stretchable than the body 1 on the body 1, and the side telescopic part 22 and the side auxiliary telescopic part 24 are provided with a power net alone. This relatively increases the stretchability around the chest and makes breathing easier. For other bodies 1, a highly stretchable polyurethane blended material is used unless otherwise specified.

[0039] In the embodiment, the back telescopic part 21 is arranged along the boundaries of the shoulder connection part 15, the rear arm outlet part 132, and the spinal telescopic part 23 and is connected to the surrounding part B1. On the other hand, by being provided away from the neck outlet part 14, the comfort around the neck is improved. Also, the spinal telescopic part 23 is provided on the center line of the body and is connected from the center (lowest end) of the neck outlet part 14 to the chest holding part B. In this way, since each telescopic control unit 2 is connected to the surrounding part B1, the end of the telescoping can be appropriately fixed, thus enhancing the telescopic performance and facilitating the support of the pectoralis minor muscle. In the embodiment, in particular, since the chest holding part B is fixed in the axial direction of the body by the cup part B2, the effect is particularly high.

[0040] Also, the rear arm outlet part 132 is provided along the outer edge of the user's scapula during wearing, so as not to hinder the movement of the scapula and to appropriately support the movement of the muscles that stop at the scapula.

[0041] Also, the arm outlet part 13 further includes a side arm outlet part 133 that connects the front arm outlet part 131 and the rear arm outlet part 132 at the side position, the telescopic control unit 2 includes a side telescopic part 22 arranged along the side arm outlet part 133, and the side telescopic part 22 is provided adjacent to the back telescopic part 21 and the cup part B2.

[0042] The rib expansion / contraction part 22 can further support the contraction of the subscapularis muscle that stops at the scapula. By being adjacent to or connected to the back expansion / contraction part 21, the contraction performance can be further enhanced. Also, since the rib expansion / contraction part 22 is connected to the cup part B2, the stability of the cup part B2 is enhanced, preventing the breasts from protruding.

[0043] Furthermore, the expansion / contraction control part 2 has a rib auxiliary expansion / contraction part 24 provided so as to be connected to the rib expansion / contraction part 22, the surrounding part B1, and the cup part B2. Thereby, the load related to the cup part B2 is dispersed and the tightening around the chest is alleviated.

[0044] As described above, since the expansion / contraction control part 2 is provided on the chest holding part B, while improving the performance of the cup part B2, in the same manner as in the first embodiment, it is easy to raise the arm and support the subscapularis muscle.

[0045] Also, the expansion / contraction control part 2 includes a spinal column expansion / contraction part 23 provided along the midline at the back body 12, thereby supporting the erector spinae muscle group and making it easier to stretch the back muscles.

[0046] Also, since the back expansion / contraction part 21 is connected to the spinal column expansion / contraction part 23, it becomes possible to reinforce the contraction of the spinal column expansion / contraction part 23, and the holding performance when bending the back is enhanced, enabling a stronger contraction of the back expansion / contraction part 21. In particular, the back expansion / contraction part 21 supports the contraction of the lower fibers of the subscapularis muscle, making it easier to expand the rib cage and facilitating the user's breathing.

[0047] Also, since the body 1 has a chest holding part that contracts and holds around the user's chest, a fixed point of the expansion / contraction control part 2 can be created around the user's chest, thus enhancing the expansion / contraction performance.

[0048] Also, since the expansion / contraction control part 2 is a belt material provided by overlapping the main body of the body 1, while facilitating manufacturing, fine adjustment of the expansion / contraction degree is possible, enabling a configuration more suitable for the user.
