[0009] Below, underwear X according to each embodiment of the present invention will be described with reference to the drawings. The description will be made in detail in the order of the configuration of the embodiment, the method of implementation, and other examples. The following embodiments are merely examples of the present invention, and the present invention is not limited to these embodiments. The term "substantially" in the application documents refers to shapes that have been chamfered or rounded, and also refers to shapes in which the elements constituting the shape have been deformed or changed in length within a range that does not impair the purpose of the shape. Elasticity refers to the ability to stretch and contract; the lower the elasticity, the greater the force required to stretch and the greater the return force (kickback) when stretched.

[0010] First Embodiment The present invention provides an undergarment comprising a stretchable body 1, the body 1 having a front body 11 covering the front half of a user's body and a back body 12 that is continuous with the front body 11 and covers the rear half of the user's body, an stretch control unit 2 that controls the degree of stretch of the body 1 is arranged in a predetermined position, and a ring-shaped arm outlet 13 from which the user can put their arms is arranged between the front body 11 and the back body 12, the arm outlet 13 including a forearm outlet 131 located on the front body 11 side and a rear arm outlet 132 located on the back body 12 side, the rear arm outlet 132 being arranged closer to the median line than the forearm outlet 131, and the stretch control unit 2 including a back stretchable unit 21 at least part of which is arranged along the rear arm outlet 132. The rear arm outlet 132 is arranged so as to overlap the user's shoulder blades when worn, and the stretch control unit 2 includes the back stretchable unit 21 at least part of which is arranged along the rear arm outlet 132.

[0011] The present invention comprises a body 1 which is a stretchable fabric material that covers the upper body of a user, and an expansion / contraction control unit 2 which is placed at a predetermined position on the body 1 and controls the degree of expansion / contraction at that position. The area of ​​the body 1 where the expansion / contraction control unit 2 is provided has lower expansion / contraction than the area where it is not provided, and is the cross-hatched area or the thick line area in the drawings.

[0012] The body 1 comprises a stretchable front body 11 covering the front half of the user's body, a stretchable back body 12 covering the back half of the user's body, an arm opening 13 extending from the front body 11 to the back body 12 and through which the user can put their arms, a neck opening 14 through which the user can put their neck, and a shoulder connecting part 15 connecting the front body 11 and the back body 12 at the neck side of the body 1 and positioned on the user's shoulders when in use.

[0013] The front body 11 and the back body 12 are made of stretchable fabric and are connected to each other at the boundaries of the sides and in the areas formed between the arm openings 13 and the neck openings 14, so as to cover the entire torso of the user like a running shirt. An elasticity control unit 2 may be used in these connected areas to prevent these areas from becoming easily stretched unintentionally. The ends of the front body 11 and the back body 12 on the torso side are folded over to reduce stretchability. The material of the front body 11 and the back body 12 is a polyurethane blend stretch material, which improves the mobility of the user's arms.

[0014] The arm outlets 13 are ring-shaped sections provided so that the user can put their arms out, and are provided symmetrically on both sides of the front body 11 and the back body 12. The arm outlets 13 further include a forearm outlet 131 provided on the front body 11 side, a rear arm outlet 132 provided on the back body 12 side, and an armpit arm outlet 133 which connects the forearm outlet 131 and the rear arm outlet 132 on the torso side of the body 1 and which is located at the side of the user when in use.

[0015] The neck opening 14 is a ring-shaped part that allows the user to expose their neck, and is positioned opposite the opening around the waist. The edges of the arm openings 13 and the neck opening 14 are preferably reinforced with a reinforcing material such as rubber to prevent fraying. The neck opening 14 is curved so as not to overlap with the user's collarbone, making it easier to raise the arms.

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

[0017] The rear arm outlet section 132 is the portion of the arm outlet section 13 on the rear body 12 from the shoulder connection section 15 to the armpit arm outlet section 133, and accounts for approximately 60% to 85% of the arm outlet section 13 on the rear body 12, surrounding the upper part of the user's armpit when viewed from behind.

[0018] The armpit / arm opening section 133 occupies 20% to 40% of the entire arm opening area and surrounds the underarms of the user. The armpit / arm opening section 133 is provided so as to overlap the front body section 11 and the back body section 12, but the area located on the back body section 12 is larger, making it easier to pull the area around the shoulder blades appropriately.

[0019] When viewed from behind, the arm openings 13 or rear arm openings 132 on the back body 12 are curved more toward the midline than the arm openings 13 or forearm openings 131 on the front body 11. This allows the user to move their shoulders more easily by naturally opening their shoulders without interfering with the movement of the scapulae. This curvature is preferably in line with the edges of the user's scapulae, which prevents significant interference between the scapulae and the arm openings 13 when worn and prevents the scapulae from dropping below a certain level. It is particularly preferable that the curvature be such that a portion of the arm openings 13 rests on the head side of the scapular spine (hanging from the medial edge to the upper edge of the scapular spine).

[0020] The stretch control section 2 is a section of the body 1 where fabric materials overlap as shown in the drawings, and in this embodiment is a section where a stretchable member is provided overlapping mainly the back body 12. The stretchability of this stretchable member is preferably approximately the same as or lower than the stretchability of the body 1. This suppresses stretching at a predetermined position of the body 1 and supports contraction, particularly when the lower trapezius muscle fibers are stretched, thereby supporting the user's posture.

[0021] The stretch control unit 2 comprises a back stretch unit 21 arranged on the back body 12, side stretch units 22 arranged at the sides, and a spine stretch unit 23 arranged along the median line of the back body 12, and these stretching actions bring the user's posture closer to the ideal posture.

[0022] In this embodiment, the back stretchable section 21 includes a back stretchable section main body 210, which is a fabric material provided from near the top end of the back body 12 to the bottom end, a neck side boundary 211 that connects the back stretchable section main body 210 to the body 1 at the neck side, and a side boundary 212 that connects the back stretchable section main body 210 to the body 1 at the side. Furthermore, the back stretchable section 21 is arranged along the boundary between the rear arm opening section 132 and the spine stretchable section 23, and connects to the lower end of the waist. In this way, the area where the stretch control unit 2 is provided in the waist direction is smaller in the part of the body 1 that contacts the torso than in the part that contacts the chest, making it easier to breathe without constricting the user's stomach. In particular, the back stretch unit 21, in addition to the above effect, supports the contraction of the lower fibers of the trapezius muscle, making it easier to expand the rib cage and making it easier for the user to breathe.

[0023] In the back stretchable section main body 210, a strip-shaped fabric material (power net) with lower stretchability than the body section 1 is arranged so as to overlap with the body section 1. In this embodiment, the fabric material is arranged on the back surface. This increases the elasticity of the back stretchable section 21, making this section less susceptible to deformation. In addition, it is arranged symmetrically with the spine stretchable section 23 as the center.

[0024] The neck boundary 211 is located in the rear arm opening section 132, connecting a position several centimeters away from the shoulder connection section 15 to the middle of the spinal extension section 23. This section supports the lower trapezius muscle fibers by engaging with the shoulder blades and pulling them toward the waist, particularly when the user raises their arms. The distance from the neck boundary 211 to the neck opening section 14 is set to increase at an accelerating rate toward the spinal extension section 23, thereby increasing the elasticity of the neck area and preventing tightness when worn, and preventing the movement of the middle trapezius muscle fibers from being hindered, thereby improving comfort. In an embodiment, zigzag stitching is further provided along the neck boundary 211, and the stitching itself is provided to control stretch, thereby further enhancing kickback in this area.

[0025] The lateral boundary 212 is a connection section that extends approximately vertically from the boundary between the rear arm extension section 132 and the side arm extension section 133 to the end on the trunk side, and is provided approximately parallel to the spinal extension section 23. This makes it possible to support the spinal extension section 23 and also to support muscle contraction from the lowest end of the lower fibers of the trapezius muscle. As with the neck boundary 211, zigzag stitching may be provided along the side boundary 212.

[0026] Additionally, the back stretchable section main body 210 is connected to the rear arm extension section 132. When posture deviates from the ideal state and the lower fibers of the trapezius muscle are stretched, a force is applied in the direction of contracting it, but by using the arm extension section 13 as the fixed point of contraction, the contraction action can be applied appropriately and powerfully.

[0027] Furthermore, the boundary of the back stretchable portion main body 210 is connected along the boundary of the spine stretchable portion 23, so that it can support the spine stretchable portion 23 in the same way as the side boundary 212.

[0028] The side stretchable sections 22 are sections that are less stretchable than the body 1 alone, which is provided along the side arm opening section 133, and are provided from a strip-shaped fabric material (power net) that overlaps with the body 1, similar to the back stretchable section main body 210. In this embodiment, the side stretchable sections 22 are provided so as to smoothly tie the end of the side arm opening section 133 on the front body 11 side from a position on the side boundary 212 that is approximately 3 cm to 5 cm towards the torso from the rear arm opening section 132.

[0029] When the shoulder blades are too far apart (for example, when shrugging the shoulders), the side stretchable sections 22 contract in the direction of narrowing the shoulder blades, thereby supporting posture. This effect can be further enhanced by including the side stretchable sections 22 in the front body 11. In addition, the side stretchable section 22 distributes the contraction action of the back stretchable section main body 210 not only to the rear arm out section 132 but also to the side arm out section 133, thereby preventing force from being applied to a specific position when contracted and improving the comfort of use.

[0030] The spinal stretchable section 23 is a low-elasticity section located on the midline of the back body 12. It is formed by connecting an elastic tape (strip) from the neck opening 14 to the bottom of the back body 12. Additionally, zigzag stitching may be provided on the spinal stretchable section 23. The spinal stretchable section 23 is at least less elastic than the back stretchable section 21, and preferably has the lowest elasticity among the stretch control sections 2, thereby supporting the erector spinae and multifidus muscles. More specifically, when the user hunchbacks, the spinal stretchable section 23 contracts, applying force to the spine in a direction that straightens the back, thereby supporting posture. The present invention maintains proper spinal curvature by supporting the contraction of the lower trapezius muscle fibers with the back stretchable section 21 and supporting the multifidus muscle and other muscles with the spinal stretchable section 23, thereby preventing and alleviating spinal stenosis and herniated discs. Furthermore, the highly elastic and strong spinal stretchable section 23 is provided to connect with the back stretchable sections 21 located on both sides, so that even if the back stretchable sections 21 are deformed asymmetrically, the central axis is less likely to shift, improving posture support performance.

[0031] 《How to use》 3, the user puts on the underwear X by exposing their arms through the arm opening portions 13 and their neck through the neck opening portion 14. At this time, parts of the rear arm opening portions 132 and the armpit arm opening portions 133 are positioned along the outer edges of the user's shoulder blades, and therefore do not interfere with the movement of the user's shoulders. Furthermore, if the user slouches and the lower fibers of the trapezius muscle are stretched, the back stretchable portion 21 acts in the direction of contraction to help maintain posture, and if the user's shoulder blades open, the side stretchable portion 22 contracts in the direction of the midline to help maintain posture. By arranging these materials adjacent to each other, it is possible to appropriately support the contraction of the lower fibers of the trapezius muscle.

[0032] Second Embodiment Hereinafter, the same components as those in the first embodiment of the second embodiment of the present invention will be designated by the same reference numerals and will not be described again. In this embodiment, the body part 1 is a so-called bra top, which is particularly suited to a woman's body and has a chest support part B that supports the user's breasts. Fig. 5 is a schematic diagram of the front side of the body 1 cut open at the shoulder connection part 15 and the side boundaries of the front body 11 and the back body 12, and Fig. 6 is a schematic diagram of the back side of the same body 1. Fig. 7 is a schematic diagram of the body when worn, with the dashed line indicating the chest support part B located under the body 1.

[0033] The present invention comprises a body 1 and an expansion / contraction control unit 2 arranged at a predetermined position on the body 1. The body 1 comprises a front body 11, a back body 12, an arm opening 13, a neck opening 14, and a shoulder connection unit 15. The body 1 has a chest support unit B arranged to overlap the back surface of the front body 11 and the back body 12. The expansion / contraction control unit 2 is arranged on the chest support unit B on the back body 12, and comprises a back expansion unit 21, a side expansion unit 22, a spine expansion unit 23, and an auxiliary side expansion unit 24 arranged adjacent to the cup unit described below, and the expansion / contraction action of these units brings the user's posture closer to the ideal posture.

[0034] The chest support part B is mainly connected to the back side of the body 1 and has two parts: a part that is provided as part of the front body 11 and a part that is provided as part of the back body 12, and each part is positioned so that a part of it overlaps with the outer part 1E of the body 1. More specifically, the outer portion 1E of the front body 11 is connected to the edge of the shoulder connection portion 15 of the chest support portion B, and the area further to the waist than that is the area where the outer portion 1E covers the chest support portion B. Furthermore, the outer portion 1E of the back body 12 is located closer to the shoulder than the arm opening portion 133, and both ends are connected to the rear arm opening portion 132, with an overlapping portion P that bridges both rear arm opening portions 132. In the area further to the waist than the overlapping portion P, the outer portion 1E covers the entire chest support portion B. Meanwhile, in the area further to the shoulder than the overlapping portion P, the chest support portion B is exposed. Furthermore, the overlapping portion P is located away from the chest support portion B on its surface, so that the overlapping portion P prevents the influence of the stretchability of the stretch control portion 2. More specifically, the outer portion 1E is connected so as to hang down from the arm portion 13 (excluding the forearm portion 131) and the neck portion 14, so as not to interfere with the stretching 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 diagonal lines.

[0035] The chest support section B has an enclosing section B1 that holds the area around the user's chest and a cup section B2 that holds a predetermined shape that fits the breasts at the lower end of the chest support section B. It also includes an arm opening section 13, and on the back body 12 side, a back stretchable section 21 and a spine stretchable section 23 are provided, and side stretchable sections 22 are provided along the arm opening section 133.

[0036] The enclosing portion B1 is a highly elastic band-shaped member that is provided so as to go around the user's chest. By holding the chest area in this way, it serves as a fixed point when expanding and contracting, improving the expansion and contraction performance of the expansion and contraction control portion 2. Furthermore, being made of a highly elastic member such as rubber improves the fit to the body.

[0037] The cup portion B2 is provided adjacent to the enclosure portion B1 and is made of a material that is thicker than the surrounding members so as to protect the breasts, thereby improving the fit to the user's body.

[0038] The stretch control section 2 is located above the chest support section B, which is located on the side that comes into contact with the user's body during use, improving stretchability. The spine stretch section 23 has the lowest stretchability, the back stretch section 21 the next lowest, and the side stretch sections 22 and side auxiliary stretch sections 24 the next lowest. In this embodiment, the back stretch section 21 is made by layering a power net, which has lower stretchability than the body section 1, on the body section 1, while the side stretch sections 22 and side auxiliary stretch sections 24 are made of power net alone. This relatively increases the stretchability around the chest, making breathing easier. The rest of the body section 1 is made of a highly stretchable polyurethane blend material unless otherwise specified.

[0039] In this embodiment, the back stretchable section 21 is arranged along the boundary between the shoulder connection section 15, the rear arm opening section 132, and the spine stretchable section 23, and is connected to the enclosing section B1. On the other hand, it is located away from the neck opening section 14, which improves comfort around the neck. The spinal extension / contraction part 23 is provided on the center line of the body, and is connected to the chest support part B from the center (lowest end) of the neck part 14 . In this way, by connecting each expansion / contraction control section 2 to the enclosing section B1, the end of the expansion / contraction can be fixed appropriately, improving the expansion / contraction performance and making it easier to support the trapezius muscles. In this embodiment, the chest support section B is fixed in position in the axial direction of the body by the cup section B2, which is particularly effective.

[0040] In addition, the rear arm opening section 132 is arranged to fit along the outer edge of the user's shoulder blades when worn, so that it does not hinder the movement of the shoulder blades and can properly support the movement of the muscles that stop at the shoulder blades.

[0041] In addition, the arm outlet section 13 further includes an underarm arm outlet section 133 that connects the forearm outlet section 131 and the rear arm outlet section 132 at the armpit position, and the stretch control section 2 includes an underarm stretch section 22 that is arranged along the underarm arm outlet section 133, and the underarm stretch section 22 is provided adjacent to the back stretch section 21 and the cup section B2.

[0042] The side stretchable sections 22 can further support the contraction of the trapezius muscles that stop at the scapulae, and the contraction performance can be further improved by being adjacent to or connected to the back stretchable sections 21. In addition, the side stretchable sections 22 are connected to the cup section B2, which increases the stability of the cup section B2 and prevents the breasts from protruding.

[0043] Furthermore, the stretch control section 2 has auxiliary side stretch sections 24 that are connected to the side stretch sections 22, the enclosure section B1, and the cup section B2, thereby dispersing the load on the cup section B2 and easing tightness around the chest.

[0044] As described above, the provision of the expansion / contraction control unit 2 on the chest holding portion B improves the performance of the cup portion B2, while making it easier to raise the arms and providing support for the trapezius muscles, similar to the first embodiment.

[0045] Furthermore, the stretch control section 2 includes a spine stretch section 23 provided along the median line in the back body 12, which supports the erector spinae muscles and makes it easier to straighten the spine.

[0046] Furthermore, by connecting the back stretchable part 21 to the spine stretchable part 23, it is possible to reinforce the contraction of the spine stretchable part 23, improving the support performance when bending the back and allowing for stronger contraction of the back stretchable part 21. In particular, the back stretchable part 21 supports the contraction of the lower fibers of the trapezius muscle, making it easier for the rib cage to expand and making it easier for the user to breathe.

[0047] In addition, the body 1 has a chest support section that contracts and supports the area around the user's chest, which allows a fixed point for the stretch control section 2 to be created around the user's chest, thereby improving stretchability.

[0048] Furthermore, the stretch control section 2 is a strip of material that is placed over the main body of the body 1, which makes manufacturing easier while allowing for fine adjustment of the degree of stretch, resulting in a configuration that is more suitable for the user.
