Description

bra

The present invention relates to a brassiere that suppresses shaking of the chest during wearing movement. More specifically, the present invention relates to a brassiere that has an effect of suppressing chest shaking during a wearing operation without impairing aesthetics, that is, an anti-vibration property, and has a proper wearing pressure and a comfortable wearing feeling.

¡Brass is one of the main purposes to make the shape of the chest clean, but it also plays a major role in suppressing chest shaking during exercise. However, even when wearing a bra, the chest often shakes greatly when walking or running. Especially when the size of the chest is large, the shaking becomes very large, causing discomfort and a burden on the wearer as well as causing drooping of the chest. As a method of reducing this shaking, a method of wearing a bra with a strong pressure is effective, but this method remarkably deteriorates the wearing comfort. Further, especially during exercise, the chest shake is further increased, and thus the problem becomes more obvious as it impedes the wearer's movement and becomes a burden. For this reason, many sports bras have been developed as bras that reduce the shaking of the chest during exercise (Patent Documents 1 and 2). However, sports bras have a large covering area and many designs that cover the cleavage in order to suppress shaking during exercise. For this reason, it lacks aesthetics and is often not preferred for daily use.

For this reason, considering daily use, it is desirable to develop a brassiere that has a wide open valley and maintains aesthetics, which reduces shaking of the chest during light daily exercises and has appropriate pressure. ing.

Patent Document 3 includes a pair of cup portions, a connecting portion that connects the front center sides of the cup portions to each other, a wing portion, and a shoulder strap portion whose end portions are connected to the pair of cup portions and the wing portion. In the brassiere, the cup portion has at least a pad, and the pad is a pad high-stress portion extending along the pad upper edge, the pad lower edge, or both, and the extension of the bust top portion of the pad A brassiere having a pad high stress portion in which the ratio S2 / S1 of the extension stress S2 of the pad high stress portion to the stress S1 is 2/1 to 80/1 is described.

In the technique described in Patent Document 3, the sub wing portion is arranged on the brassiere body in a region extending from the cup portion to a part of the wing portion. By placing sub-wings made from fabric cloths with different tensile stresses from the fabric of the main body, due to the difference in tensile stress between the main body fabric and the sub-wings when worn, the joints of the sub-wing parts in the cup part are directed toward the wing parts. The pulling force works and the anti-vibration effect is demonstrated.

In the above bra, it is possible to suppress shaking during operation without sacrificing comfort, while opening a cleavage gap greatly due to the effect of the sub wing part. However, the subjective evaluation of the feeling of shaking and comfort when wearing this brassiere is improved compared to a normal brassiere and the shaking value is reduced, but depending on the wearer, there is a little in terms of comfort. There was a sense of discomfort.

JP 2005-23497 A JP 2011-179144 A Japanese Patent Laid-Open No. 2014-163018

Therefore, the problem to be solved by the present invention is to provide a brassiere that is excellent in vibration reduction of the chest during exercise, i.e., excellent in anti-vibration properties, and preferably in addition to anti-vibration properties, aesthetics and comfort. Is to provide a better bra.

The present inventors have confirmed that the bust is actually finely swayed in the three-dimensional direction in the cup even in a product that suppresses the shaking of the entire bust, such as the brassiere shown in Patent Document 3. Found by measurement used. In terms of acceleration, the product that suppresses the shaking of the entire bust suppresses large shaking of the chest, but acceleration due to fine vibrations occurs in all directions, and the chest is always subjected to shock caused by acceleration. Will be. This is considered to be the cause of the uncomfortable feeling, although the shaking at the time of wearing is settled. For this reason, in order to further improve the wear comfort, it is considered necessary to reduce the occurrence of this acceleration.

Furthermore, it was found that some wearers may feel uncomfortable in the cup. That is, when the sub wing part is provided as the vibration isolating part, the sub wing part is pulled from the joint part of the sub wing part toward the wing part due to the difference in tensile stress between the sub wing part provided in the cup part and the main body fabric, particularly the wing part. It has been found that since the force works and the anti-vibration effect is exerted, a force greater than that of the main body fabric is applied to the cup portion, and the bust may be uncomfortable. In particular, in a brassiere in which a metal wire is provided at the lower part of the cup part in order to adjust the shape of the bust, there may be a sense of incongruity that the metal wire bites into the lower part of the bust. For this reason, in order to further improve the wearing comfort, it is considered necessary to reduce the uncomfortable feeling caused by the wire biting in.

As a result of intensive studies to solve the above-mentioned problems and repeated experiments, the present inventors set the physical properties of the connecting portion connecting the cup portions to a predetermined value in a brassiere having an opening portion and a specific vibration isolating portion. Thus, it has been found that the acceleration during operation can be suppressed without increasing the wearing pressure. Furthermore, in the brassiere having the sub wing part as the vibration isolator, the physical property of the sub wing part is set to a specific value, and further, the physical properties of the main body fabric, particularly the wing part and the sub wing part are set to a specific ratio. The inventors have found that it is possible to suppress the biting of the metal wire into the lower part of the bust and to improve the vibration proofing including the acceleration suppression during the operation, and have completed the present invention. That is, the present invention is as follows.

Examples of typical aspects of the present invention are described in detail below.
One aspect of the present disclosure includes a pair of cup portions, a connecting portion that connects the front center sides of the cup portions to each other, a wing portion adjacent to the side of the cup portion, and an end portion of the pair of cup portions and the wing A bra with a shoulder strap connected to the portion, and a tensile stress at the time of the third extension in the 10% repeat extension test of the connecting portion is 10N to 30N, and has a specific vibration isolator. Provide a bra. By making the connecting portion and the specific vibration-proofing portion coexist, a higher vibration-proofing effect can be obtained than when only the connecting portion is present.

Referring to FIG. 1, a brassiere 100 according to one embodiment of the present invention includes a pair of cup portions 102 (in the drawing, one of the pair is shown as a region surrounded by a dotted line), and a front portion of the cup portion. The connecting part 101 which mutually connects a center side, and the wing part 103 (this is arrange | positioned at the side of the cup part 102 (namely, a wearer's side)) are provided. The connection part 101 may extend along the lower edge of the cup part 102 as a lower side tape, for example, and may form the brassiere lower end. The wing 103 extends toward the wearer's back. The wing portion 103 can have a base portion and a lower side portion (for example, a tape). Each member is made of a fabric. The brassiere further includes a shoulder strap portion 110 having an end portion connected to the wing portion 103 and the pair of cup portions 102.

In the bra of the present disclosure, the cup is assumed to accept the wearer's breast. Moreover, it is assumed that a connection part connects the front center side of this cup part mutually. Further, it is assumed that the shoulder strap portion extends from the front portion and is stretched over the shoulders on the left and right sides of the wearer and then connected to the wing portion on the back side of the wearer.

In the present disclosure, “wearer side” means the back side of the brassiere (that is, the side where the cup has a concave shape), and “outside” means the side opposite to the wearer side.

In the present disclosure, the “horizontal direction” (for example, the horizontal direction of the connecting portion) referred to with respect to the brassiere is an arrangement direction of the two cups, and specifically, the bust top positions of the two cups are most distant from each other. The direction of the straight line connecting the two bust top positions when the brassiere is placed on is intended. In the present disclosure, the “vertical direction” of the brassiere is a direction perpendicular to the horizontal direction, and is intended to correspond to the vertical direction of the wearer's body.

In the present disclosure, the “bust top position” means a position corresponding to the wearer's bust top when the brassiere is worn (that is, a position corresponding to the wearer's nipple). The bust top position is the top of the bulge shape (convex shape) of the cup. In the present disclosure, the “front center line” and the “back center line” of the brassiere are lines extending in the vertical direction of the brassiere through the midpoint of the line segment connecting the two bust top positions, respectively. The line is on the front and the back center line is on the wing.

In the present disclosure, the circumferential length of the brassiere is the shortest length of a line drawn from the front center line through the back center line to return to the front center line in the main body (however, the brassiere is a length adjusting mechanism (for example, described later) 4 is intended to be a value obtained by adjusting the length adjusting mechanism so that the circumferential length is maximized.

In this disclosure, the extension stress at the time of the third extension in the 10% repeat extension test of the connecting part 101 connecting the front center sides of the cup part to each other is 10N to 30N. Furthermore, in the brassiere of the present disclosure, by combining one or more specific vibration isolating portions in addition to the connecting portion, it becomes possible to suppress fine vibration during operation, and to reduce the load during operation on the body. It can reduce and can have high comfort.

Usually, the cup is assumed to accept the wearer's breast. However, in practice, in the cup, the chest is not completely along the cup and is not fixed. For this reason, when the chest shakes during operation, it is considered that the chest vibrates in the cup. This fine vibration is generated in any direction of the X, Y, and Z directions even if the chest does not oscillate in appearance. This is because when the brassiere is worn, when it is stretched in the horizontal direction when worn, the stretching force in the horizontal direction starts from the stretching of the wing part, and the fabric of the cup connecting part is stretched. For this reason, it is thought that a connection part floats and a clearance gap will generate | occur | produce between skin. It is thought that this gap will reduce the fixing force of the cup by generating an area where the cup and chest are not installed near the front of the cup, that is, an area where the chest can escape. It is done. For this reason, it is presumed that this phenomenon causes the feeling of shaking and the feeling of strangeness even when the appearance is not greatly shaken at the time of wearing.

It is advantageous from the viewpoint of suppressing the shaking that the extension stress at the third extension in the 10% repeat extension test in the horizontal direction of the connecting part is 10N to 30N. The tensile stress is preferably 15N to 25N. When the tensile stress is 10 N or more, the connecting portion is difficult to expand, and the connecting portion becomes a fixing point, so that the connecting portion does not float and the chest can be fixed from the front surface of the cup to the side surface. It is possible to suppress vibration. Moreover, since it is not too hard at the time of wear as it is 30 N or less, it becomes possible to suppress a shake without impairing comfort.

In addition, the extensional stress in the horizontal direction is specifically measured as the stress when each part is extended in the horizontal direction (for example, the direction of a straight line L1 in FIG. 3 described later). Unless otherwise specified, the elongation and elongation stress of the present disclosure are values measured in accordance with the JIS L106.88.12.1 A method cut strip method tensile test.

The physical property values mentioned in this disclosure may be measured by grasping the end of each part of the brassiere (for example, the connecting part), or may be measured by cutting out the fabric from each part, unless otherwise specified. It is intended that the physical property value measured by any method should be the value of the present disclosure.

The connecting portion is not particularly limited as long as it is a fabric that satisfies the above requirements, but a knitted fabric including spandex fibers, such as a cotton fabric, a polyester woven fabric, a polyamide woven fabric, or a knitted fabric of a power net structure or a two-way knitted fabric. It can be exemplified that it is constituted by the ground.

Providing a sub-wing part, providing a high stress part on the upper and / or lower edge of the cup, and providing an anti-vibration part on the shoulder strap part also suppresses large external shakes and at the same time provides specific physical properties. Due to the synergistic effect with the effect of pulling the chest to the trunk by the connecting portion having the contact, it is possible to further suppress fine shaking by further tightly contacting the cup and the chest.

In a particular embodiment, the brassiere has an upper edge high stress portion (eg, upper edge high stress portion 104 in FIG. 1) that extends along the upper edge of the cup.

In a particular embodiment, the brassiere has a lower edge high stress portion (eg, lower edge high stress portion 105 in FIG. 1) that extends along the lower edge of the cup.

Referring specifically to FIG. 2, in a particular embodiment, the brassiere has a sub-wing portion 109 as a vibration isolator. By wearing the sub wing part, the dough stretches from the cup part to the wing part. By pulling the chest in the trunk direction of the body, the adhesion between the cup and the breast is improved, and these are integrated. It has an excellent effect of preventing the chest from floating during operation. Thereby, it is possible to suppress a large shake on the appearance during operation.

The sub wing part 109 is arranged on the main body in a region extending from a part of the cup part 102 to a part of the wing part 103. The sub wing part 109 can typically be constituted by one or a plurality of fabrics arranged from the side edge of the cup part 102 to the wing part 103. The sub wing portion 109 is not configured to be integrated with the main body portion in the cup portion 102 and the wing portion 103, but is formed of a fabric separate from the main body portion and overlapping the main body portion.

The subwing portion 109 and the main body typically have the following two joint portions.
In the first joint portion, the brassiere 100 is arranged so that the line segment I connecting the bust top H of each cup portion 102 and the back center C of the corresponding wing portion is the longest, and is identical to the line segment. When a plane S having a normal in the direction is defined, 0 to 25%, preferably 5 to 25%, more preferably 8 to 23% from the bust top H on the line segment I toward the back center C Exists on the plane of the position. When the position of the first joint portion is 0% or more from the bust top toward the back center C, it is advantageous that the tensile force is not excessively applied to the bust top. On the other hand, when the position of the joint portion is 25% or less from the bust top toward the back center C, the force that pulls the bust toward the body side is easy to work and is advantageous.
The second joint portion is 50 to 100%, preferably 50 to 85%, more preferably 55 to 80% from the bust top H on the line segment I toward the back center C with respect to the plane S described above. Exists on the plane of the position. When the position of the second joint is 50% or more from the bust top toward the center of the back, it is advantageous that a tensile force is easily applied to the bust top. On the other hand, when the position of the joint is 100% or less from the bust top toward the center of the back, it is advantageous that the force that pulls the bust toward the body is easy to work.

The joint between the sub wing 109 and the main body is related to the plane S defined above, on the plane at a position of 0 to 25% from the bust top H on the line segment I toward the back center C and 50 It suffices to exist on the plane at a position of ˜100%, and may further exist in a part other than the plane. However, from the viewpoint of obtaining a better anti-vibration effect by the subwing portion 109, with respect to the plane S, for example, a position of more than 25% to less than 50% from the bust top to the back center C on the line segment I, It is more preferable that no joint exists on the plane at a position of 25 to 55% or a position of 28 to 60%.

The boundary between the cup part 102 and the wing part 103 is usually on the plane S at a position of 25 to 35% from the bust top on the line segment I toward the back center C. Therefore, when joints are present on the planes at the positions of 0 to 25% and 50 to 100%, the sub wing portion is located at each of the cup portion 102 and the wing portion 103 at a preferred position for vibration isolation. This is advantageous because 109 can be joined to the body.

A joint portion between the sub wing portion 109 and the main body can be formed in a linear shape (typically a strip shape having a predetermined width), a dot shape, or the like. For example, joint portions extending linearly in a substantially vertical direction can be formed in the left and right cup portions 102 and the left and right wing portions 103. In a preferred embodiment, the sub wing portion 109 has a region that is joined to the main body portion in both of a partial region of the cup portion 102 and a partial region of the wing portion 103 and is not joined to the main body portion. In a preferred embodiment, the sub wing portion 109 is overlapped with a main body portion of a region that is continuous over a region 107 a that is a part of the cup portion 102 and a region 107 b that is a part of the wing portion 103. By the sub wing part 109, the side reinforcement part which consists of the area | region 107a and the area | region 107b can be formed. That is, the side reinforcement portion is constituted by a bonded fabric including the main body portion and the sub wing portion 109.
In a preferred embodiment, the sub wing part 109 is joined to the main body part in a region including both ends of the sub wing part on the cup part 102 side and the wing 103 part side.

In a preferred embodiment, the subwing portion 109 is joined so as to have a space between the main body portion. In this aspect, the sub wing part 109 only needs to cover at least a region formed by a part of the cup part 102 of the main body part and at least a part of the wing part 103. Further, the sub wing part 109 may be joined to the main body part in a region including at least a part of the peripheral edge of the sub wing part 109 (for example, both ends on the cup part 102 side and the wing part 103 side). 109 may be joined to the main body only at a portion other than the periphery. The sub wing part 109 is joined to the main body part so that a space exists between the sub wing part 109 and the main body part. Here, the space is an area where the sub wing part 109 and the main body part are not joined, which are sandwiched between the joint parts or surrounded by the joint parts. In order to form such a space, it is preferable to form the joint portion in the shape of two or more points, two or more lines, and the like. For example, an example of two or more points is a combination of one or more points in the region of the cup part 102 and one or more points in the wing part 103. Further, for example, an example of two or more lines is a combination of the cup portion side joint portion 107aS and the wing portion side joint portion 107bS shown in FIG. For example, when two dotted joints are formed, the space means a region extending between the region connecting the two points of the sub wing unit 109 and the region connecting the two points of the main body unit. . In this space, the sub wing part 109 and the main body part may be in a state where they are not joined, and they may be in contact with each other. According to the configuration as described above, a tensile force can be generated between the joint portions when worn due to a difference in tensile stress between the fabric of the sub wing portion 109 and the fabric of the main body portion, so that a vibration isolation effect is exhibited. .

With reference to FIG. 2, in a specific embodiment, the sub wing portion 109 is at least at both ends of the cup portion 102 side and the wing portion 103 side, that is, in an area including both ends of the cup portion 102 side and the wing portion 103 side. While having joined with the main-body part, it has the area | region which is not joined to the main-body part. In the preferred embodiment, as shown in FIG. 2, the main body portion and the sub wing portion 109 are joined only by the cup portion side joint portion 107aS and the wing portion side joint portion 107bS, and the sub wing portion 109 has a region other than these. Then, it is not joined to the main body. Due to the presence of the sub wing portion 109, a pulling force from the cup side end portion of the sub wing portion 109 toward the wing side when worn is exerted, thereby exhibiting an anti-vibration effect.

Of the area of the area that receives tensile force when the sub-wing part 109 is worn, the area of the area that is not joined to the main body part is preferably 30% or more, more preferably 60%, from the viewpoint of obtaining a good anti-vibration effect. Above, more preferably 80% or more, and preferably 99.5% or less, more preferably 99% or less, and still more preferably 98% from the viewpoint that the sub-wing part 109 and the main body part are firmly joined. It is as follows. It should be noted that the area of the region receiving the tensile force when worn is the intersection line closest to the front center and the back center C with respect to the intersection line between the surface perpendicular to I and passing through the joint portion and the surface of the subwing 109. This is the area of the sub-wing fabric that exists in the region sandwiched between the close intersection lines.

Referring to FIG. 3, a line segment L2 that defines the shortest distance from the straight line L1 drawn so as to be in contact with the lower end of the brassiere to the boundary point Pa between the upper edge of the cup and the side edge of the cup is hypothesized. Of the intersecting lines between the plane passing through the segment L2 and perpendicular to the segment L2, and the fabric surface of the main body (the outer surface as viewed from the wearer), select the intersecting line that maximizes the length in the region 107a. The intersection of the intersection line and the side edge of the cup is M1, and the intersection of the intersection line and the side edge of the side reinforcement portion at the cup side joint 107aS is M2, and M1 and M2 on the intersection line A line segment between them is defined as a line segment La. Let M3 be the intersection of the line of intersection and the edge of the wing side joint 107bS on the side reinforcement portion end side. A line segment between M1 and M3 on the intersection line is defined as a line segment Lb.

The length of the wing portion 103 is from the point M1 to the back center of the wing portion 103 (the boundary with the hook portion if a hook portion is provided at the end of the wing portion 103, or the back center when worn if there is no hook portion; 4 means the shortest length on the fabric up to point Pc).

The length of the wing portion 103 is suitably 5 cm to 15 cm.

The length m1 of the sub wing portion 109 is the shortest length in the cloth connecting the point M2 and the point M3 of the joint portion with the main body portion. Further, the total length of the line segment La and the line segment Lb in the main body portion is defined as a length m2 between the joint portions of the main body portion. Usually, bras are worn in an extended state. E1 = {(1 + E2 / 100) × (m2 / m1) −1} × 100 E1 = {(1 + E2 / 100) × 1} × 100 (1)
100 / YR1 ≦ E1 ≦ 1000 / YR1 (2)
It is preferable to satisfy both conditions.
Here, the horizontal direction of the subwing portion 109 is the direction of the line segment that is the shortest length in the fabric connecting the points M2 and M3. Here, the length m1 of the sub wing portion 109 and the length m2 between the joint portions in the main body are numerical values that should be determined by the design and appearance of the brassiere. Underbust size) / (perimeter of the lowermost part of the brassiere) × 100} −100 (%), which is a numerical value to be determined by the size.
Using these numerical values, the horizontal direction expansion ratio E1 of the sub wing portion 109 when the brassiere is worn is calculated according to the equation (1). It is preferable that E1 satisfies the formula (2) in order to suppress the uncomfortable feeling during wearing and operation while sufficiently exhibiting the vibration proofing property. In the formula (2), YR1 is a Young's modulus in the horizontal direction of the subwing portion 109, which will be described later. If the calculated E1 does not satisfy equation (2) according to equation (1), YR1 is changed by changing the material of the subwing unit 109 so that equation (2) is satisfied. Or it is also preferable to change E1 so that Formula (2) may be satisfied by changing any one or combination of m1, m2, and E2 by changing the design, appearance shape, and size.

Due to the elongation rate E1, the transverse direction stress σ1 generated in the subwing portion 109 is 100 cN / inch ≦ σ1 ≦ 1000 cN / inch (3)
It is preferable to satisfy. When σ1 is 100 cN / inch or more, sufficient vibration-proofing properties are exhibited, and when σ1 is 1000 cN / inch or less, the pressure applied, particularly the pressure at the shoulder and the lower part of the bust, does not become too high, and the feeling of tightening The biting feeling is suppressed. Preferably, 200 cN / inch ≦ σ1 ≦ 800 cN / inch, and particularly preferably 300 cN ≦ σ1 ≦ 600 cN / inch. Σ1 corresponding to E1 can be determined from the stress-strain relationship of the material used for the subwing portion 109 measured separately.

Further, the ratio of the transverse direction Young's modulus YR1 of the sub wing portion 109 to the transverse direction Young's modulus YR2 of the wing portion 103 is 0.7 ≦ YR1 / YR2 ≦ 3 (4)
It is preferable to satisfy. Here, the horizontal direction of the wing portion 103 is a direction along the line segment Lb. If 0.7 ≦ YR1 / YR2, it is possible to obtain sufficient anti-vibration properties while maintaining a beautiful appearance without making the length of the sub-wing portion 109 extremely short compared to the length of the wing portion 103. If YR1 / YR2 ≦ 3, the sub-wing portion 109 can be compared with the wing portion, and a stress that exhibits vibration-proofing properties can be obtained without excessively extending, and the feeling of biting into the lower portion of the bust can be suppressed. Preferably, 1 ≦ YR1 / YR2 ≦ 2.5, and particularly preferably 1.1 ≦ YR1 / YR2 ≦ 2. YR1 and YR2 are values calculated by a conventional method from the slope of the strain of 0 to 10% in the stress-strain relationship obtained in accordance with the cut strip method of JIS L10968.8.12.1 A method.

The method for determining the shape and physical properties of the subwing unit 109 is as follows. M1, m2, and E2 are determined according to the design, appearance, and size of the brassiere, and the horizontal direction expansion ratio E1 of the subwing portion 109 is calculated according to the equation (1). Using the transverse Young's modulus YR1 of the subwing portion 109, it is confirmed from the formula (2) whether the above E1 is within an appropriate range. At that time, it is also confirmed that the ratio of the Young's modulus in the horizontal direction between the sub wing portion 109 and the wing portion 103 satisfies the expression (4). If E1 is not in an appropriate range, E1 is set in an appropriate range by changing the fabric used for YR1, that is, the sub-wing portion, m1, m2, that is, the design of the brassiere, changing the appearance, and changing the size of E2, that is, the brassiere. Next, the stress σ1 at the stretch rate E1 is obtained from the stress-strain relationship of the fabric of the subwing portion 109, and it is confirmed that the expression (3) is satisfied, and the shape and physical properties of the subwing portion 109 are determined.

When the stress σ1 of the subwing portion 109 does not satisfy the equation (3), that is, when σ1 is less than 100 cN / inch, the subwing portion 109 is applied to a fabric having a large YR1 within a range satisfying the equations (2) and (4). By changing the length m1 of the sub wing part 109 to a short design, measures such as increasing the horizontal expansion ratio E1 when worn are taken. Conversely, if σ1 exceeds 1000 cN / inch, the subwing portion 109 is changed to a fabric with a small YR1 within the range that satisfies the equations (2) and (4), and the length m1 of the subwing portion 109 is made longer. By changing, take measures such as reducing the horizontal expansion ratio E1 when wearing.

The height of the sub wing part 109 is represented by the length of a line segment (not shown) perpendicular to L1 of the sub wing part. The greater the height, the greater the anti-vibration effect. Therefore, it is preferable that the joint part on the cup part 102 side extends over the upper end and the lower end of the cup, and the joint part on the wing part 103 side preferably extends over the upper end and the lower end of the wing. Furthermore, it is preferable that the height of the sub wing portion 109 is equal to or higher than the height of the main body portion at a portion other than the joint portion.

The sub wing part 109 greatly contributes to the vibration proofing in the X and Z directions among the shaking in the X, Y, and Z directions of the chest. That is, the subwing portion 109 is excellent in the effect of improving the adhesion between the cup and the chest and integrating them, and has the effect of preventing the chest from protruding during operation. The effect of improving the adhesion between the cup and the chest and integrating them is particularly effective due to the anti-vibration property in the Z direction, and the effect of preventing the breast from protruding is particularly the anti-vibration property in the X direction where tensile force is applied. Is more effective.

The sub wing portion 109 is not particularly limited as long as it satisfies the above-mentioned requirements, but spandex fibers such as cotton fabric, polyester woven fabric, polyamide woven fabric, power net fabric, two-way fabric, etc. It can be exemplified that the knitted fabric includes a knitted fabric including The frictional force between the front side of the main body fabric and the back side of the sub wing fabric may affect the vibration isolation effect. Accordingly, this frictional force is preferably 0.10 to 0.20 when the frictional force between the two is evaluated using, for example, a KES-SE friction tester manufactured by Kato Tech Co., Ltd. or an equivalent device. More preferably, it is 0.18. If the friction force is 0.10 or more, the sub wing fabric easily exerts the effect of pressing the main body fabric, and if it is 0.20 or less, the sub wing fabric has the effect of pressing the main body fabric in that the friction is not too large. Easy to demonstrate. The frictional force can be adjusted by a combination of the main body fabric and the sub-wing 109 fabric.

The subwing portion 109 can be joined to the main body portion by sewing, welding, or other methods. For example, when the joint part of the sub wing part 109 with the main body part is at both ends of the cup part 102 side and the wing part side of the sub wing part, it is for the main body part at both the cup part 102 side and the wing part side. The sub wing portion 109 can be formed by overlapping the fabric and the fabric for the sub wing portion 109 and fixing them by stitching, welding, or other methods. When the cup part 102 has two or more layers, it may be joined to one of them or all the layers. When the tensile stress of the fabric on the cup body surface is small, even if only the surface fabric is joined, the fabric is stretched and the effect of pulling the cup is small, so it is joined to the cup body so that only the surface fabric is not stretched It is preferable to sew.

The sub wing part pulls the cup diagonally backward (corresponding to the combined direction of the X direction and the Z direction), and pulls the chest in the trunk direction, thereby improving the adhesion between the cup and the chest. At the same time, however, there is a tendency for the chest to be pulled closer to the side compared to a bra without subwings. For this reason, at the same time, the connecting portion is stretched by being pulled in the left-right direction by the pulling force caused by the subwing. For this reason, in the vicinity of the connecting portion (chest center), a gap is likely to be formed between the cup and the chest as compared with the brassiere without subwing. At this time, in the brassiere having the sub wing part, the connecting part has a predetermined stress, so that the connecting part becomes a fixing point, and further, a pulling force that draws the chest toward the trunk is generated, and the connecting part floats. It becomes possible to suppress, and it becomes possible to suppress the fine shaking at the time of operation.

In another aspect, the anti-vibration effect can be exhibited by disposing the high stress portion 104 on the upper edge portion of the cup. The upper edge high stress portion is disposed so as to extend along the cup upper edge portion. The upper edge high stress portion may constitute at least a part of the substantial peripheral portion of the cup portion.

In the cup part, the ratio S2 / S1 of the extension stress S2 of the upper edge high stress part to the extension stress S1 of the center part is preferably 2/1 to 400/1. In the present disclosure, the center part of the cup means an area including a top part of the cup (that is, a position corresponding to the top part of the wearer's bust) and having a single tensile stress. In the present disclosure, the term “extension stress” refers to a 10% elongation stress (N / 2.5 cm width, hereinafter simply referred to as N) of a fabric in accordance with the cut strip method tensile test of JIS L1096.88.12. And a value obtained by measuring the stress (N) when stretched by 10% in the horizontal direction and averaging them (hereinafter, also referred to as “vertical average tensile stress” or simply “extension stress”).

When the cup part is composed of two or more layers (for example, two layers of urethane pad and fabric), the tensile stress is measured in a state where two or more layers are stacked.

If the ratio S2 / S1 is 2/1 or more, the effect of suppressing the shaking of the chest due to the high stress portion is large. On the other hand, if the ratio S2 / S1 is 400/1 or less, it is possible to avoid a brassiere that is hard and difficult to fit because the tensile stress in the high-stress part does not become too high. The ratio S2 / S1 is preferably 3/1 to 100/1, more preferably 5/1 to 80/1, and particularly preferably 10/1 to 60/1.

The upper edge high stress part greatly contributes to the vibration proofing property in the X and Y directions of the chest in the X, Y and Z directions. When walking, running, etc., the chest in the cup goes up and down with some delay from the vertical movement of the human body. In this case, the upward shaking of the chest can be effectively suppressed by providing the upper edge high stress portion. Furthermore, in addition to the vertical movement of the human body during a movement such as walking or running, a horizontal movement that rotates the body also occurs simultaneously. Furthermore, when the upper edge high stress portion is provided so as to extend along the upper edge of the cup, the upper edge high stress portion can be usually attached slightly obliquely with respect to the horizontal direction. Thereby, it is possible to suppress the inward movement of the chest due to the left-right movement, that is, the X-direction swing.

It is preferable that the upper edge high stress part is disposed over the width of 0.5 to 5.0 cm on the upper part of the cup part. More preferably, the width is 1.0 to 4.0 cm. Moreover, the said width | variety can be designed arbitrarily. For example, the width of the upper edge high stress portion can be designed to be thin on the front center side of the wearer's body of the cup portion and thick on the side side.

Moreover, in another aspect, the vibration proof effect can be expressed by arranging the high stress part 105 in the lower edge part of the cup. The lower edge high stress part is arranged extending along the lower edge part of the cup part. In addition, the lower edge high stress part should just comprise at least one part of the substantial peripheral part of a cup part.

In the cup part, the ratio S3 / S1 of the extension stress S3 of the lower edge high stress part to the extension stress S1 of the center part is preferably 2/1 to 400/1. If S3 / S1 is 2/1 or more, the effect of suppressing chest shaking due to the high stress portion is great. On the other hand, if the ratio S3 / S1 is equal to or less than 400/1, it is possible to avoid a brassiere that is hard and difficult to fit because the tensile stress in the high-stress part does not become too high. The ratio S3 / S1 is preferably 3/1 to 100/1, more preferably 5/1 to 80/1, and particularly preferably 10/1 to 60/1.

The lower edge high-stress part greatly contributes to the vibration-proofing property in the Y direction among the shaking in the X, Y and Z directions of the chest. When walking, running, etc., the chest in the cup goes up and down with some delay from the vertical movement of the human body. In this case, the shaking of the chest that strikes downward can be effectively suppressed by providing the lower edge high stress portion.

It is preferable that the lower edge high stress portion is disposed at a lower portion of the cup portion over a width of 0.5 to 4.0 cm. The width is more preferably 1.0 to 3.0 cm. The width can be designed arbitrarily. For example, the cup portion can be designed to be thin on the front center side of the wearer's body and thick on the side side.

When both the upper edge high stress part and the lower edge high stress part are provided, the ratio of the sum of the areas of the upper edge high stress part and the lower edge high stress part to the entire cup part area is 10% to 50%. It is preferably 20% to 40%. When the said ratio is 10% or more, a reinforcement effect is large and even if it is a big cup, the chest shaking suppression effect is acquired favorably. On the other hand, when the said ratio is 50% or less, the discomfort at the time of wear can be avoided favorably. The area ratio between the upper edge high stress portion and the lower edge high stress portion is not particularly limited. The ratio can be calculated, for example, by stacking thin paper on the cup surface and calculating the mass of the paper corresponding to the area of each part of the cup.

The extension stresses S2 and S3 of the upper edge high stress portion and the lower edge high stress portion are each preferably 20 to 500N, more preferably 50 to 400N, and still more preferably 100 to 350N. When the tensile stress is 20 N or more, the reinforcing effect is large, and when it is 500 N or less, discomfort during wearing can be avoided well. The elongation stress ratio between the upper edge high stress portion and the lower edge high stress portion is not particularly limited. Further, the tensile stress at the center is preferably 0.5 to 50N, more preferably 1 to 20N, still more preferably 1.5 to 15N, and particularly preferably 2 to 10N. When the tensile stress is 0.5 N or more, tearing or the like hardly occurs at the time of wearing and washing, and when it is 50 N or less, discomfort at the time of wearing can be favorably avoided.

When the upper edge high stress portion and / or the lower edge high stress portion is formed in the cup portion, a portion having a high tensile stress may be disposed at a predetermined position of the cup by changing the knitting structure and the yarn used denier. Good. Moreover, the method of sewing or adhering the reinforcement cloth used as an upper edge high stress part or a lower edge high stress part to the inner side (namely, wearer skin surface side) of a brassiere can be used. Alternatively, when a urethane pad is used for the cup, a method of increasing the rigidity of a part of the pad may be used by sandwiching a fabric that becomes a high-stress part when the urethane pad is molded. .

In a specific embodiment, the shoulder strap portion as the vibration isolation portion has an average cross-sectional area of 20 to 120 mm ² . In this case, it is possible to achieve good vibration isolation. The average cross-sectional area is more preferably 25 to 100 mm ² . The cross-sectional area means the width (mm) of the shoulder strap x the thickness (mm) of the shoulder strap. The average cross-sectional area is the number average value of the cross-sectional areas measured at both ends of the shoulder strap portion and at each portion that is divided into 10 equal parts. Specifically, the average cross-sectional area can be calculated as follows.

1 and 4, the average cross-sectional area of the shoulder strap portion is calculated by the width W1 × thickness (not shown) of the end portion (that is, the base portion) of the shoulder strap portion on the cup portion side (that is, the front side). Cross-sectional area, cross-sectional area calculated by width W2 × thickness (not shown) of the end portion (that is, the base portion) on the wing portion side (that is, the rear side), and the end portion on the cup portion side and the wing portion side With respect to cross sections (ie, nine cross sections) that divide between the end portions by 10 in the length direction of the shoulder strap portion, each width × thickness (not shown) (for example, width W3 × thickness in FIG. 1) is calculated. Is the arithmetic average value of the cross-sectional area. The width W1 and the width W2 mean the shortest distances from the side connection points P1 and P2 between the shoulder strap portion and the cup portion and the wing portion, respectively, to the center side of the shoulder strap portion. When an adjuster for adjusting the length of the shoulder strap is provided, the length of the adjuster is maximized for measurement.

The weight of the chest is greatly applied to the shoulder strap portion, and particularly when the cup size is large, the force becomes very large. Therefore, in the case of a sports bra and a brassiere with a large cup size, a device for increasing the width of the shoulder strap is devised. However, when the width of the shoulder strap portion is wide, the sexyness is lost and the beauty is inferior. Even if the width of the shoulder strap portion is narrow, by increasing the cross-sectional area of the shoulder strap portion, vibration can be absorbed and the cup portion can be supported stably. When the average cross-sectional area of the shoulder strap portion is smaller than 20 mm ^2, the effect of absorbing vibration tends to be small. Vibration is absorbed when the average cross-sectional area of the shoulder strap is larger than 120 mm ² , but the aesthetics are impaired when the width is increased, and when the thickness is increased, the texture such as stiffness and the sound of the outer Tend to be a problem. However, when the reinforcement is applied at other parts of the brassiere as described above, if the average cross-sectional area of the shoulder strap is 20 mm ² or more, for example, about 80% or more, the excellent vibration-proofing property of the brassiere can be maintained. it can. For example, when one or more of the upper edge high stress portion, the lower edge high stress portion, and the sub wing portion are provided, the average cross-sectional area of the shoulder strap portion can be set to 16 mm ² or more and 120 mm ² or less.

The back side connection center of the shoulder strap part is preferably located 25 to 60%, more preferably 30 to 50% of the length of the wing part from the back center of the wing part toward the cup part side. When the deviation of the back side connection center of the shoulder strap part from the back center of the wing part is 25% or more, there is an advantage of excellent vibration isolation, and when it is 60% or less, the shoulder strap part is less likely to slide down. There is. The length of the wing portion is defined as described above. In addition, the back side connection center of the shoulder strap portion in FIG. 4 is a perpendicular line drawn from the midpoint of the line segment forming the width W2 to a line segment forming the length of the wing portion, and a line forming the length of the wing portion. Means the intersection with the minute.

The elongation (power) of the shoulder strap portion is measured by an elongation at a load of 0.5 N / mm ^{2 in} the length direction, and is preferably 30 to 80%, more preferably 40 to 70%. . Elongation can be measured in accordance with the JIS L10968.8.12.1 A method cut-strip method tensile test, but the entire shoulder strap is gripped and the measurement load is a load obtained by multiplying the average cross-sectional area by 0.5N. And If the power of the shoulder strap portion is 30% or more, it will not be too hard and can absorb vibrations well. If the power of the shoulder strap portion is 80% or less, the elongation does not become too large and vibrations can be absorbed well.

It is preferable that the shoulder strap part 110 has a low-stress part having a tensile stress smaller than that of the other part in a part. By providing such a low-stress part, concentration of wearing pressure can be prevented and comfort can be enhanced. For example, referring to FIG. 1, it is desirable to have a low-stress part having a lower tensile stress than the other part in the region including the shoulder part 110 a.

The shoulder strap part greatly contributes to the vibration-proofing property in the Y direction among the shaking in the X, Y and Z directions of the chest. The human body moves up and down during walking, running, etc., and with some delay, the chest in the cup moves up and down, but the shoulder strap with a cross-sectional area above a certain level supports the cup from above. Thus, the vertical movement of the chest can be suppressed. Furthermore, by attaching the shoulder strap portion near the side rather than near the center, it greatly contributes to vibration isolation in the X direction among the shaking in the X, Y, and Z directions of the chest. By attaching the shoulder strap portion near the side, a force that pulls the cup diagonally upward works, so that it is possible to effectively suppress bust shaking due to the rotation of the human body during an operation such as walking or running. The shoulder strap is attached to the front side approximately 3cm from the side edge of the cup in the X direction, and the rear side from the midpoint between the back center and the side center (ie, between the front center and the back center). A position within 5 cm on the side is preferred. Furthermore, since the shoulder strap part is pulling the front cup toward the rear side of the body, it contributes to vibration isolation in the Z direction.

As described above, the brassiere of the present invention uses a member having predetermined physical properties for the cup connecting portion, and the vibration isolating portion includes the sub wing portion, the upper edge high stress portion of the cup, and the lower edge high stress portion of the cup. , And a combination of one or more of the shoulder strap portions having a specific average cross-sectional area, particularly when a sub-wing portion is provided, in particular, the sub-wing portion has specific physical properties, and the wing portion and the sub-wing. When the part has a specific physical property ratio, a special vibration-proofing effect can be exhibited. In particular, by combining the anti-vibration effects in the respective X, Y, or Z directions, the anti-vibration properties can be further enhanced. For example, the combination of the connecting part and the sub-wing part with the upper edge high stress part of the cup or the lower edge high stress part of the cup or the shoulder strap part, or a combination of two or more of these may cause vibrations in the X, Y and Z directions. Can be reduced and dispersed, which is highly preferred. Further, when the vibration isolating portion is a combination of two or more of the sub wing portion, the upper edge high stress portion of the cup, the lower edge high stress portion of the cup, and the shoulder strap portion having a specific average cross-sectional area. It is also possible to reduce the lower limit value of a preferable range of characteristic values in each of the above (especially, the tensile stress ratio for the high stress portion and the average cross-sectional area of the shoulder strap portion) by about 20%. For example, when the average cross-sectional area of the shoulder strap portion is 20 to 120 mm ² , good vibration isolating properties can be obtained. Good vibration resistance is obtained with a cross-sectional area of 16 to 120 mm ² .

Each member may be formed of a separate fabric, or may be formed of a continuous fabric, and the boundary between the members may be defined only by the shape. In the latter case, in particular, the outer edge of the cup portion is defined as the position of the edge if the edge of the bulge of the cup is clear, or as the position considered as the edge assumed from the bulge shape if it is unclear.

The anti-vibration part may be configured as a reinforcing part of a fabric different from the main body. For example, the sub wing part is joined to the fabric constituting the main body (also referred to as body cloth in the present disclosure) as described above. It is attached. Such a reinforcing portion has an advantage that vibration proofing is better than that provided in the body cloth by power switching or the like (that is, by applying strength of extensional stress).

The body fabric may be formed of separate fabrics, or may be formed of a continuous fabric, and the boundary between members may be defined only by the shape. In the latter case, in particular, the outer edge of the cup is defined as the position of the edge if the edge of the bulge of the cup is clear, and the position considered as the edge assumed from the bulge shape if it is unclear.

Referring to FIG. 5, in a specific aspect, when the brassiere is arranged so that the distance between the cup front center points Q1 and Q2 of the shoulder strap portion is maximum, the cup front front end point Q1 of the shoulder strap portion. The area ratio of the portion 111 not covered with the brassiere material to the area of the triangle T formed by connecting Q2 and the front center lower end point Q3 of the connecting portion is preferably 60% or more, and 70% or more. More preferably, it is more preferably 80% or more, and most preferably 100%. This triangle forms what is called a cleavage. When the said ratio is 60% or more, it can prevent that a valley hides and can implement | achieve favorable aesthetics. The brassiere of the present invention can have a specific shaking value as described below, which is achieved by, for example, having a specific vibration isolator. The brassiere of the present disclosure is advantageous in that it has excellent vibration-proofing properties even in a so-called open state in which the ratio is 60% or more.

Referring to FIG. 6, when the brassiere is arranged so that the distance between the front end of the shoulder strap and the center of the cup portion is the maximum in the vertical length of the connecting portion, the cup bottom points B1 and B2 are Corresponds to the length of the line segment L3 connecting the midpoint K of the line segment and the midpoint R of the line segment connecting the front center side end points Q1 and Q2 of the shoulder strap to the connecting portion on the line segment L3 The length ratio L4 / L3 of the line segment L4 is preferably 0.10 to 0.50, and more preferably 0.15 to 0.45. In addition, the line segment L4 corresponding to the connection part site | part on the line segment L3 means the set of the intersections of the perpendicular drawn down on the line segment L3 from the connection part, and the line segment L3. Since the above-mentioned ratio is 0.10 or more, the installation area of the connecting part is sufficiently secured, so that the cup and the chest are in close contact with each other in the center part of the cup, and the lateral direction starting from the wing part that occurs when worn By being a fixing point against the stretching force, it is possible to firmly fix the chest from the front surface to the side surface of the cup, and to suppress fine vibrations. In addition, by being 0.50 or less, the area of the connecting portion does not become excessively large, and the opening area of the chest can be sufficiently maintained, and at the same time, the connecting portion is hardened. Therefore, wearing comfort does not decrease.

The brassiere of the present disclosure exhibits good vibration isolation properties by having a specific vibration isolation unit. Therefore, since the wearing pressure of each part can be reduced to 50 hPa or less while suppressing the shaking of the chest, the maximum wearing pressure of the present disclosure can be reduced to 50 hPa or less, and an unpleasant tightening feeling during wearing can be avoided. Generally, in order to suppress the shaking of the chest, tightening is often strong, and in particular, there are bras with extremely high shoulder pressure. However, when the pressure applied to each part of the brassiere exceeds 50 hPa, it generally tends to be uncomfortable. In the present invention, since the movement of the chest in each of the X, Y, and Z directions is suppressed and distributed, concentration of wearing pressure can be prevented. In particular, the reinforcement of the shoulder strap described above is excellent in the effect of dispersing the pressure. The maximum pressure is more preferably 45 hPa or less, and still more preferably 40 hPa or less. On the other hand, the maximum wearing pressure can be, for example, preferably 10 hPa or more, more preferably 13 hPa or more, and still more preferably 15 hPa or more, from the viewpoint of suppressing deviation during wearing and suppressing shaking.

The material of each member of the brassiere of the present disclosure (that is, a member constituting the body fabric and the reinforcing portion) is not particularly limited, and synthetic fibers such as polyester fibers and polyamide fibers, cellulosics such as rayon, cupra, and acetate Fibers and natural fibers such as cotton and hemp are preferably used. The structure of the fabric constituting each member is not particularly limited, and a knitted fabric, a woven fabric, a non-woven fabric, or the like is used. Further, crimped fibers may be used. In the present invention, it is effective to arrange a fabric having an appropriate stretch characteristic on each member. In each member, a knitted fabric having an elongation in which polyurethane elastic fibers are knitted is suitably used. Moreover, a double round knitting, a tricot knitting, a Russell knitting, etc. can be used for the cloth of a cup and a wing part, and a tricot half cloth is used suitably. The knitting gauge of the knitting machine used is preferably 20 to 40 GG. In addition, a woven fabric or warp knitted fabric or the like is preferably used for the high stress portion, and a slightly stretched lace or the like is excellent in design and is very preferably used.

Each member can be composed of monofilament or multifilament. Multifilament yarns include matting agents such as titanium dioxide, stabilizers such as phosphoric acid, UV absorbers such as hydroxybenzophenone derivatives, crystallization nucleating agents such as talc, easy lubricants such as aerosil, hindered phenol derivatives, etc. Antioxidants, flame retardants, antistatic agents, pigments, fluorescent brighteners, infrared absorbers, antifoaming agents and the like may be contained.

<The total fineness of the fabric material which comprises each member of the brassiere of this indication can be the range generally used by clothing etc. Among these, from the viewpoint of strength and softness, the total fineness is preferably about 22 to 700 dtex.

The basis weight of the fabric used for each member of the brassiere is not particularly limited, but is preferably about 50 to 500 g / m ² .

In addition, it is desirable that the fabric used for each member be subjected to water absorption processing.

When a urethane pad is used for the cup, a urethane pad having a thickness of 2 to 15 mm is preferably used, but it is also preferable to increase the air permeability by using a three-dimensional knitted fabric for the cup.

Although it does not specifically limit as a fabric used for a reinforcement part, It is comprised with the cloth containing polyurethane elastic fibers, such as a cotton fabric, a polyester woven fabric, a knitted fabric of a polyamide material, or a knitted fabric of a power net structure, a knitted fabric of a two-way structure, etc. can do.

The brassiere of the present disclosure is extremely excellent in vibration isolation. In order to objectively evaluate the degree of shaking, the following method can be used. Five subjects with a height of 160cm ± 8cm (top bust dimension-under bust dimension) of 17.5cm or more wear a brassiere, and the treadmill speed is 5.5km / h and the pace is 150 steps per minute. Then, make a short run so that one leg is away from the ground when landing. At this time, a reflection sphere having a diameter of 2.0 cm is attached to the clavicle portion and the bust top portion, and the reflection sphere is photographed with two high-speed cameras for 20 seconds. As an indicator of chest sway when the clavicle part swings to about 13 cm, (bust top sway)-(clavicle sway) (cm) for 20 seconds (maximum average)-( The average of the minimum values (cm) is calculated in three directions: horizontal (X), vertical (Y), and depth (Z). Here, the X direction means the horizontal direction of the brassiere, and the Y direction and the Z direction are each perpendicular to the X direction. The largest value among the values in the three directions is the vibration (cm) when worn, and the value is divided by the value (cm) of (top bust dimension−under bust dimension). If the shaking value is 0.4 or less, the shaking is small and advantageous. The shaking value is preferably 0.3 or less, and more preferably 0.2 or less. The smaller the swing value, the better. However, from the viewpoint of avoiding excessive pressure and easily obtaining a good wearing feeling, for example, it is preferably 0.03 or more.

In order to objectively evaluate the degree of fine shaking of the chest in the cup in the present disclosure, the following method can be used. When evaluating the above-mentioned appearance of chest shaking, a 3-axis accelerometer (SA12ZSCA: manufactured by Fuji Ceramics Co., Ltd.) is directly attached to the vicinity of the subject's bust top (it will be located inside the brassiere). Run at a speed of 5.5 km / h on a red mill at a pace of 150 steps per minute so that one foot is off the ground when landing. In this measurement, acceleration in the x direction (horizontal direction), y direction (vertical direction), and z direction (depth direction) was measured, and (average of maximum values)-(average of minimum values) in each direction. ) (M / s ² ) is calculated for each of the three directions. The lower the acceleration, the smaller the fine shaking of the chest in the cup, and the smaller the value is desirable. In particular, the vibration of 50 m / s ² or less makes it possible to suppress the fine vibration of the chest in the cup and to reduce the uncomfortable feeling during the wearing operation.
