Description

The present invention relates to a brassiere that suppresses the shaking of the chest during wearing operation. More specifically, the present invention relates to a brassiere having an effect of suppressing chest shaking during wearing operation, that is, vibration isolation without impairing comfort.

One of the main purposes of a brassiere is to shape the chest neatly, but one of the major roles is to suppress the shaking of the chest during exercise. However, even if you are wearing a bra, your chest often shakes greatly when you walk or run. Especially when the size of the breast is large, the shaking becomes very large, which not only causes discomfort and burden on the wearer, but also causes drooping of the breast. As a method of reducing this shaking, a method of wearing a brassiere with a strong wearing pressure is effective, but this method significantly deteriorates wearing comfort. In addition, during exercise, the swaying of the chest becomes even greater, which makes the problem more apparent, such as hindering or burdening the wearer's movements. For this reason, many sports brassieres have been developed as brassieres for reducing chest shaking during exercise (Patent Documents 1 and 2). However, sports bras are often designed to cover the cleavage of the chest with a large covering area in order to suppress shaking during exercise. For this reason, it lacks aesthetics and is often not preferred for everyday use.

For this reason, considering daily use, it is desirable to develop a brassiere that widens the cleavage of the chest, maintains aesthetics, reduces chest shaking during daily light exercise, and has appropriate pressure. ing.

However, there is also a desire to make the volume look smaller in sizes with large breasts. This is due to the desire to make the appearance look slim by making the bust volume look smaller.

Patent Document 3 describes a pressing portion that presses the bust of a portion that contacts a region extending from the front center portion of the cup portion to the side portion via the bust top peripheral portion, and at least a part of the lower portion of the pressing portion. , A brassiere comprising an easily swelling area for the pressed bust volume to swell.

Patent Document 4 includes a pair of cup portions, a connecting portion that connects the front center side of the cup portion to each other, a wing portion, and a shoulder cord portion whose ends are connected to the pair of cup portions and the wing portion. In a brassiere, the cup portion has at least a pad, and the pad is a pad high stress portion extending along the upper edge of the pad, the lower edge of the pad, or both of them, 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.

According to the brassiere described in Patent Document 3, although it is possible to make the bust volume look small, it does not pay attention to the shaking of the chest during operation, and it cannot be said that the wearing comfort is sufficient.

Further, in the brassiere of Patent Document 4, the sub-wing portion is arranged on the brassiere body in the region extending from the cup portion to a part of the wing portion. By arranging sub-wings made from fabrics with different tensile stress from the main body fabric, the difference in tensile stress between the main body fabric and the sub-wing during wearing causes the joint portion of the sub-wing portion in the cup portion to be directed toward the wing portion. The pulling force works to exert the anti-vibration effect. Due to the effect of such a sub-wing portion, it is possible to suppress shaking during operation without impairing comfort while widening the cleavage of the chest. However, such a brassiere was intended to bring out the bust volume firmly, and could not fully meet the desire to make the bust volume look smaller.

Therefore, the problem to be solved by the present invention is to provide a brassiere having an effect of reducing chest shaking during exercise, that is, a brassiere having excellent vibration isolation, and preferably, in addition to vibration isolation, it is also excellent in comfort. It is to provide a brassiere that can make the bust volume look smaller.

As a result of diligent research and repeated experiments to solve the above problems, the present inventors maintain high anti-vibration properties by the sub-wing portion of the specific arrangement in the brassiere having the opening and the specific anti-vibration portion. However, they have found that it is possible to make the bust volume look small even in a large size without increasing the wearing pressure, and have completed the present invention. That is, the present invention is as follows.

It is provided so as to extend over the position. That is, the cup-side joint can extend through the portion (1) above in the vertical direction of the brassiere.

In a particular embodiment, the cup-side joint has a cup upper joint end that resides on the cup upper edge peripheral edge and a cup lower joint end that resides on the cup lower end peripheral edge. In the following, the point on the front center side of the cup upper joint end point is defined as the cup upper front center end point, the point on the back center side is defined as the cup upper back center end point, and the point on the front center side of the cup lower joint end points. Will be described as the front center end point of the lower part of the cup, and the point on the most dorsal center side will be described as the back center end point of the lower part of the cup. The upper joint end of the cup and the lower joint end of the cup may be one point each. In this case, the front center end point of the upper part of the cup and the back center end point of the upper part of the cup are the same points, and the front center end point of the lower part of the cup. And the end point of the lower back center of the cup are understood to be the same point. However, from the viewpoint of obtaining good vibration isolation, it is preferable that the front center end point of the upper part of the cup and the back center end point of the upper part of the cup are different, and the front center end point of the lower part of the cup and the back center end point of the lower part of the cup are different. Is preferable. In particular, from the viewpoint of obtaining the height of the sub-wing portion, it is preferable that the cup upper joint end portion exists at two or more points, and it is more preferable that the cup upper dorsal center end point exists on a line extending from the point P to the point P1. ..

In a preferred embodiment, the cup upper joint end is continuous from the cup upper anterior center end point to a different point, the cup upper dorsal center end point. Further, in a preferred embodiment, the cup lower joint end portion is continuous from the cup lower front center end point to the cup lower back center end point, which is a different point.

Further, in a preferred embodiment, the cup portion side joint portion includes a line segment extending from the cup upper front center end point to the line segment L1 intersecting with the cup lower front center end point.

The cup side joint is preferably closer to the anterior center side from the viewpoint of making the chest volume look smaller. In a preferred embodiment, the cup upper front center end point is located at point Q, the cup upper dorsal center end point is located at point P, the cup lower joint end is located at point W (as one point), and the cup side joint is located. Includes a line segment extending from the point P1 to the intersection point W with the line segment L1. In this embodiment, the cup upper joint end is further present at any position on the upper edge of the cup (more preferably over the entire area from point P to point Q) in addition to the points P and Q. Is preferable. Further, in this embodiment, the cup portion and the sub wing portion are formed at an arbitrary position on a line segment extending from the point Q to the point W along the peripheral edge of the cup portion (more preferably over the entire area from the point Q to the point W). Further, it is preferable that they are joined.

In a particular embodiment, the line segment connecting the upper back center end point of the cup and the upper end point of the wing side joint, which will be described later, is the upper side of the sub wing, and the lower back center end point of the cup and the lower end point of the wing side joint, which will be described later. The line segment connecting with is the lower end of the sub wing.

When at least a part of the wing portion side joint portion defines a plane S having a normal in the same direction as the line segment I on the line segment I connecting the bust top H to the back center C at the shortest distance. It exists on the plane at a position of 55 to 100%, preferably 55 to 95%, of the distance from the bust top H to the back center C from the bust top H toward the back center C. When the position of the wing side joint is 55% or more of the distance from the bust top to the center of the back, it is possible to easily apply a pulling force to the bust, obtain high vibration isolation, and make the bust volume look small. Become. On the other hand, if the position of the wing portion side joint is 100% or less of the distance from the bust top to the center of the back, a force that pulls the bust toward the trunk of the body is likely to work, and high vibration isolation can be obtained. In certain embodiments, the wing side joints are present over the entire area of the sub wing on the plane. In this embodiment, the upper end point and the lower end point of the wing portion side joint portion are the upper end and the lower end of the sub wing portion, respectively. In a preferred embodiment, the wing portion side joint is formed linearly on the plane S. In another preferred embodiment, the wing portion side joint portion may be joined at the joint portion between the hook portion (length adjusting mechanism portion 106) and the wing portion.

The sub-wing portion 109 can be joined to the main body by suturing, welding or other methods. For example, the sub wing portion 109 is formed by stacking the fabric for the main body and the fabric for the sub wing portion 109 at the joint portion on the cup portion side and the joint portion on the wing portion side and fixing them by suturing, welding, or other methods. it can. For example, when the main body is composed of two or more layers of fabric, it may be bonded to one layer or all layers. For example, if the tensile stress of the dough on the surface of the cup body is small, the dough will be stretched even if it is joined only to the surface dough, and the effect of pulling the cup will be small. It is preferable to join, suture, etc. to the main body of the part.

Of the area of the sub-wing portion that receives tensile force when worn, the area of the non-joined portion (that is, the region that is not joined to the main body) is preferably 30% or more from the viewpoint of obtaining a good anti-vibration effect. It is more preferably 60% or more, still more preferably 80% or more, and from the viewpoint that the sub wing portion and the main body are firmly joined, it is preferably 99.5% or less, more preferably 99% or less, still more preferably. Is 98% or less.

The sub-wing portion length is typically the length of the line segment La + Lb defined as described below. How to obtain the length of the wing portion, the width of La and the width of Lb will be described below with reference to FIG.

A line segment K2 that defines the shortest distance from the straight line K1 drawn so as to touch the lowermost end of the brassiere to the boundary point Pa between the upper edge of the cup and the side edge of the cup is virtualized. Of the intersections between the plane that passes through line segment K2 and is perpendicular to line segment K2 and the surface of the fabric of the main body (the outer surface when viewed from the wearer), the intersection line that maximizes the length in the cup region is defined. Select, the intersection of the intersection line and the side edge of the cup is M1, the intersection of the intersection line and the edge of the sub-wing portion end side of the cup portion side joint 107aS is M2, and M1 and M2 on the intersection line. Let the line segment between and be the line segment La. The intersection of the line of intersection and the edge of the wing portion side joint portion 107bS on the sub wing portion end side is defined as M3. The line segment between M2 and M3 on the intersection is defined as the line segment Lb.

The length of the wing portion is the fabric from the point M1 to the back end of the wing portion (the boundary with the hook portion when the wing portion has a hook portion, and the back center C when worn if there is no hook portion). Means the shortest length above.

The appropriate length of the line segment K2 is 5 cm to 25 cm.

The sub-wing portion length m1 is the shortest length in the fabric connecting the points M2 and M3 at the joint with the main body. Further, the total length of the line segment La and the line segment Lb in the main body is defined as the length m2 between the joints of the main body. Bras are usually worn in a stretched state. Assuming that the horizontal extension rate when the sub wing is worn is E1,
E1 = {(m2 / m1) x (1 + E2 / 100) -1} x 100 (1)
It is preferable to satisfy.

Here, the horizontal direction of the sub-wing portion is the direction of the line segment having the shortest length in the fabric connecting the points M2 and M3. Here, the length m1 of the sub-wing portion and the length m2 between the joint portions in the main body are numerical values to be determined by the design and the appearance shape of the brassiere. Note that E2 represents the elongation rate of the main body in the horizontal direction when worn, and is defined by the following formula.
E2 = {(Underbust size / Perimeter at the bottom of the brassiere) x 100} -100
E2 is a number that should be determined by the size of the brassiere according to the above formula.
Using these numerical values, the extension rate E1 in the horizontal direction of the sub-wing portion when the brassiere is worn is calculated according to the equation (1).
Regarding the relationship between the sub-wing portion length m1 and the joint portion length m2 of the main body, it is preferable to satisfy the following relationship.
1.01 × m1 ≦ m2 ≦ 1.5 × m1 (2)
Since the length of the sub wing is shorter than the length of m2 between the joints, the sub wing can be worn without loosening during product and wearing, and it has sufficient anti-vibration performance while maintaining a beautiful appearance. Is possible.

In the elongation rate E1, the horizontal stress σ1 generated in the sub-wing portion is 100 cN / inch ≦ σ1 ≦ 1000 cN / inch (3).
It is preferable to satisfy.

When σ1 is 100 cN / inch or more, sufficient anti-vibration property is exhibited and the effect of reducing bust volume is exhibited, and when σ1 is 1000 cN / inch or less, pressure is applied, especially on the shoulder and bust. Does not become too high, and the feeling of tightening is suppressed. Preferably, 150 cN / inch ≦ σ1 ≦ 800 cN / inch, and particularly preferably 200 cN / inch ≦ σ1 ≦ 600 cN / inch. The evaluation of the relationship between the elongation stress and the elongation rate is carried out in accordance with the cut strip method of JIS L1096.8.12.1 A.

Further, the Young's modulus YR1 in the horizontal direction of the sub wing portion 109 and the Young's modulus YR2 in the horizontal direction of the wing portion 103 are 0.5 ≦ YR1 / YR2 ≦ 3 (4).
It is preferable to satisfy. When YR1 / YR2 is 0.5 or more, the length of the sub wing portion 109 is not extremely shortened in comparison with the length of the wing portion 103, and sufficient vibration isolation is provided while maintaining the beautiful appearance. If YR1 / YR2 can be obtained and YR1 / YR2 is 3.0 or less, stress for exhibiting vibration isolation can be obtained without extending the sub-wing portion 109 extremely in comparison with the wing portion, and the bust portion. The feeling of tightening can be suppressed. Preferably, 0.5 ≦ YR1 / YR2 ≦ 2.5, and particularly preferably 0.7 ≦ YR1 / YR2 ≦ 2.0. For YR1 and YR2, the load was converted into stress by referring to the following formula from the load-strain relationship obtained in accordance with the cut strip method of JIS L1096.8.12.1 A, and the strain was 0 to 0. It is calculated as the slope of 0.1 part.
Stress [N / m ² ] = Load at strain 0.1 [N] / (Measurement width of fabric [m] x Thickness of fabric [m])
Young's modulus (YR1 and YR2) [Pa] = stress [N / m ² ] / (0.1)

The method for determining the shape and physical properties of the sub wing portion 109 is as follows. M1, m2, and E2 are determined according to the design, appearance, and size of the brassiere, and the horizontal extension rate E1 of 109 of the sub-win portion is calculated by the equation (1). After that, it is confirmed that the ratio of the Young's modulus in the horizontal direction of the sub-wing portion 109 and the wing portion 103 satisfies the equation (4). After that, the stress at the elongation rate E1 of the sub wing portion 109 fabric is obtained, it is confirmed that the equation (3) is satisfied, and the shape and physical properties of the sub wing portion 109 are determined if it is within an appropriate range. If it is not in an appropriate range, the fabric used for the sub-wing portion is changed, m1 and m2, that is, the design of the brassiere, the appearance and E2 are changed, that is, the brassiere size is changed so that the range is adjusted to an appropriate range.

The height of the sub wing portion 109 is represented by the length of a line segment perpendicular to K1 of the sub wing portion, and the larger the height, the greater the anti-vibration effect. Therefore, in the cup portion, it is preferable that a part of the joint portion exists at W1 (line segment from P to P1) which is the boundary between the cup portion and the shoulder strap portion, and the joint portion on the wing portion 103 side is the upper end of the wing. It is preferable that it extends over the lower end. Further, in the portion other than the joint portion, the height of the sub wing portion 109 is preferably equal to or higher than the height of the main body.

The fabric of the sub wing does not necessarily have to be more stretchable than the fabric of the main body, and by adjusting the lengths of m1 and m2 according to the stretchability of the sub wing according to the above formula, the brassiere fits the skin. The effect is enhanced, and a tensile force is applied to the cup portion side joint portion of the sub wing portion when worn, so that the anti-vibration effect can be exhibited.

The sub-wing portion greatly contributes to the vibration isolation of the chest in the X, Y, and Z directions, especially in the X and Z directions. That is, the sub-wing portion has an excellent effect of enhancing the adhesion between the cup and the chest and integrating them, and has an effect of preventing the chest from protruding during operation. The effect of enhancing the adhesion between the cup and the chest and integrating them is particularly effective due to the vibration isolation in the Z direction, and the effect of preventing the chest from sticking out is the vibration isolation in the X direction, which is particularly attractive. Is more effective. Here, the X direction means the horizontal direction of the brassiere when worn, and the Y direction and the Z direction are perpendicular to the X direction, respectively. Therefore, the X direction is the horizontal direction, the Y direction is the vertical direction (height direction), and the Z direction is the depth direction.

The sub-wing part pulls the cup diagonally backward (corresponding to the combined direction of the X and Z directions), which makes it possible to pull the chest toward the trunk, improving the adhesion between the cup and the chest. .. By increasing the adhesion between the cup and the bust, it is possible to suppress the movement of the chest in the cup, and it is possible to suppress the shaking in the Y direction as a whole.

The sub-wing portion can be composed of a fabric having a smaller elongation than the main body fabric such as a cotton woven fabric or a polyester woven knitted fabric, or a fabric having a higher elongation than the main body fabric such as a knitted fabric having a power net structure. When the joints of the sub-wing portion with the main body are both ends of the cup portion side and the wing portion side, the fabric for the main body and the fabric for the sub wing portion are overlapped and sewn at both ends of the cup portion side and the wing portion side. The sub-wing portion can be formed by welding or fixing by other methods.

In addition to the sub-wing part, by providing a high stress part on the upper edge and / or lower edge of the cup, and by providing a vibration-proof part on the shoulder strap part, large shaking in appearance is suppressed, and at the same time, the chest is placed on the trunk. Due to the synergistic effect with the pulling effect, the cup and chest are in close contact with each other, which makes it possible to further suppress small shaking.

In certain embodiments, the brassiere has an upper edge high stress portion extending along the upper edge of the cup (eg, upper edge high stress portion 104 in FIG. 2). The anti-vibration effect can be exhibited by arranging a high-stress portion on the upper edge of the cup. The upper edge high stress portion is arranged so as to extend along the upper edge portion of the cup. The upper edge high stress portion may form at least a part of a substantially peripheral portion of the cup portion.

In the cup portion, the ratio S2 / S1 of the extension stress of the upper edge high stress portion S2 to the extension stress S1 of the central portion is preferably 2/1 to 400/1. In the present disclosure, the central portion of the cup means a region including the bust top H of the cup portion (that is, the position corresponding to the top portion of the wearer's bust) and having a single tensile stress. In the present disclosure, the extensional stress is the stress during extension of 10% in the vertical direction (N / 2.5 cm width, hereinafter simply referred to as N) of the fabric in accordance with the cut strip method tensile test of JIS L1096.8.12.1 A. The stress (N) at 10% extension in the horizontal direction is measured and averaged (hereinafter, also referred to as vertical / horizontal average extension stress or simply extension stress).

When the cup portion is composed of two or more layers (for example, two layers of urethane pad and cloth), the elongation stress is measured with the two or more layers stacked.

When 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, when the ratio S2 / S1 is 400/1 or less, the elongation stress in the high stress portion does not become too high, and it is possible to avoid a brassiere that is hard and difficult to fit. 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 portion greatly contributes to the vibration isolation of the chest in the X, Y, and Z directions, especially in the X and Y directions. During movements such as walking and running, the chest contained in the cup moves up and down with some delay with respect to the vertical movement of the human body. In this case, the upward sway of the chest can be effectively suppressed by providing the upper edge high stress portion. Furthermore, during movements such as walking and running, in addition to the vertical movement of the human body, left and right movements that rotate the body also occur at the same time. Further, if 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 usually be attached at a slight angle with respect to the horizontal direction. This makes it possible to suppress the inward sway of the chest due to the left-right movement, that is, the sway in the X direction.

The upper edge high stress portion is preferably arranged on the upper portion of the cup portion over a width of 0.5 to 5.0 cm. The width is more preferably 1.0 to 4.0 cm. Further, the above width can be arbitrarily designed. For example, the width of the upper edge high stress portion can be designed to be narrow on the front center side of the wearer's body of the cup portion and thick on the side.

In certain embodiments, the brassiere has a lower edge high stress section extending along the lower edge of the cup (eg, lower edge high stress section 105 in FIG. 2). The anti-vibration effect can be exhibited by arranging a high stress portion on the lower edge of the cup. The lower edge high stress portion is arranged so as to extend along the lower edge portion of the cup portion. The lower edge high stress portion may form at least a part of a substantially peripheral portion of the cup portion.

In the cup portion, the ratio S3 / S1 of the extension stress of the lower edge high stress portion S3 to the extension stress S1 of the central portion is preferably 2/1 to 400/1. When S3 / 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, when the ratio S3 / S1 is 400/1 or less, the elongation stress in the high stress portion does not become too high, and it is possible to avoid a brassiere that is hard and difficult to fit. 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 portion greatly contributes to the vibration isolation of the chest in the X, Y, and Z directions, especially in the Y direction. During movements such as walking and running, the chest contained in the cup moves up and down with some delay with respect to the vertical movement of the human body. In this case, the swaying of the chest that hits downward can be effectively suppressed by providing the lower edge high stress portion.

The lower edge high stress portion is preferably arranged at the lower part 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 above width can be designed arbitrarily. For example, the cup can be designed to be thin on the front center side of the wearer's body and thick on the 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 total area of the cup part is 10% to 50%. It is preferably present, and particularly preferably 20% to 40%. When the above ratio is 10% or more, the reinforcing effect is large, and even with a large cup, the effect of suppressing the shaking of the breast can be obtained satisfactorily. On the other hand, when the above ratio is 50% or less, discomfort during wearing can be satisfactorily avoided. The area ratio between the upper edge high stress portion and the lower edge high stress portion is not particularly limited.

The extension stresses S2 and S3 of the upper edge high stress portion and the lower edge high stress portion are preferably 20 to 500 N, more preferably 50 to 400 N, and further preferably 100 to 350 N, respectively. 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 satisfactorily avoided. The elongation stress ratio between the upper edge high stress portion and the lower edge high stress portion is not particularly limited. The tensile stress at the central portion is preferably 0.5 to 50 N, more preferably 1 to 20 N, still more preferably 1.5 to 15 N, and particularly preferably 2 to 10 N. When the tensile stress is 0.5 N or more, tearing or the like is unlikely to occur during wearing and washing, and when it is 50 N or less, discomfort during wearing can be satisfactorily avoided.

When forming an upper edge high stress part and / or a lower edge high stress part in the cup part, a part having a high tensile stress is arranged at a predetermined position of the cup by changing the knitting structure, the number of denier of the yarn used, etc. You may. Further, a method of sewing or adhering a reinforcing cloth to be the upper edge high stress portion or the lower edge high stress portion can be used on the inside of the brassiere (that is, the wearer's skin surface side). Alternatively, when a urethane pad is used for the cup, a method of increasing the rigidity of a part of the pad by sandwiching a woven fabric or the like that becomes a high stress portion may be used when molding the urethane pad. ..

The reinforcing cloth is not particularly limited, but a cotton fabric, a polyester woven knitted fabric, a woven or knitted fabric made of a polyamide material, a knitted fabric having a power net structure, a knitted fabric having a two-way structure, or the like containing polyurethane elastic fibers can be used. ..

In certain embodiments, the shoulder straps have an average cross-sectional area of 20-120 mm ² . Such a shoulder strap portion can function as a vibration-proof portion, and vibration-proof properties can be achieved even better. The average cross-sectional area is more preferably ^{25 to 100 mm 2.} The cross-sectional area means the width of the shoulder strap (mm) x the thickness of the shoulder strap (mm). 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 each portion divided into 10 equal parts. Specifically, the average cross-sectional area can be calculated as follows.

With reference to FIGS. 1 and 4, the average cross-sectional area of the shoulder strap is calculated by the width W1 × thickness (not shown) of the end (that is, the base) of the shoulder strap on the cup side (that is, the front side). Cross-sectional area, the cross-sectional area calculated by the width W2 x thickness (not shown) of the end (that is, the base) on the wing side (that is, the rear side), and the end on the cup side and the wing side. For the cross section (that is, nine cross sections) that divides the area between the end and the shoulder strap into 10 equal parts in the length direction of the shoulder strap, each width x thickness (not shown) (for example, width W3 x thickness in FIG. 1) is calculated. It is the number average value of the cross-sectional area to be made. The width W1 and the width W2 are the connection points P1 or the back center side on the front center side of the shoulder strap portion from the connection points P and P'on the side of the shoulder strap portion and the cup portion and the wing portion, respectively. It means the shortest distance to the connection point P'1 of. If 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 heavy on the shoulder straps, especially when the cup size is large. Therefore, in the case of sports bras and brassieres with a large cup size, the width of the shoulder straps is increased. However, when the width of the shoulder strap is wide, the aesthetics are inferior. Even when the width of the shoulder strap is narrow, by increasing the cross-sectional area of the shoulder strap, vibration can be absorbed and the cup can be stably supported. When the average cross-sectional area of the shoulder strap ^{is smaller than 20 mm 2,} the effect of absorbing vibration tends to be small. If the average cross-sectional area of the shoulder strap ^{is larger than 120 mm 2} , vibration will be absorbed, but if the width is increased, the aesthetics will be impaired, and if the thickness is increased, the texture such as stiffness and the sound to the outer will be affected. Tends to be a problem. However, if the brassiere has a reinforcing portion (for example, an upper edge high stress portion and / or a lower edge high stress portion) in addition to the sub wing portion and the shoulder strap portion, the average cross-sectional area of the shoulder strap portion is 20 mm ² . For example, if it is about 80% or more, the excellent anti-vibration property of the brassiere can be maintained. For example, the average cross-sectional area of the shoulder strap ^{can be 16 mm 2} or more and 100 mm ² or less.

The dorsal connecting center of the shoulder strap portion is located at a position preferably 15 to 80%, more preferably 30 to 60% away from the back center of the wing portion toward the cup portion side in the length of the wing portion. When the deviation of the dorsal connection center of the shoulder strap from the back center of the wing is 15% or more, there is an advantage of excellent vibration isolation, and when it is 60% or less, the shoulder strap is hard to slip off. There is. The length of the wing portion is defined as described above. Further, the dorsal connection center of the shoulder cord portion is a perpendicular line drawn from the midpoint of the line segment forming the width W2 to the line segment forming the length of the wing portion and a line forming the length of the wing portion in FIG. It means the intersection with the minute.

The elongation (power) of the shoulder strap is ^{measured by the elongation under 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 according to the cut strip method tensile test of JIS L1096.8.12.1 A, but the entire shoulder strap is used as the grip interval, and the measured load is the average cross-sectional area multiplied by 0.5N. And. If the power of the shoulder strap is 30% or more, it will not become too hard and vibration can be absorbed well. If the power of the shoulder strap is 80% or less, the elongation does not become too large and the vibration can be absorbed well.

It is preferable that the shoulder strap portion 110 has a low stress portion having a tensile stress smaller than that of the other portion. By providing such a low stress portion, it is possible to prevent the concentration of the wearing pressure and enhance the comfort. For example, referring to FIG. 1, it is desirable to have a low stress portion having a smaller tensile stress than the other portions in the region including the shoulder portion 110a.

The shoulder strap portion greatly contributes to the vibration isolation of the chest in the X, Y, and Z directions, especially in the Y direction. When walking, running, etc., the human body moves up and down, and with some delay, the chest contained in the cup moves up and down, but the shoulder straps with a certain cross-sectional area support the cup from above. As a result, the vertical movement of the chest can be suppressed. Furthermore, by attaching the shoulder strap portion not near the center but near the side, it greatly contributes to the vibration isolation in the X direction among the swings in the X, Y, and Z directions of the chest. By attaching the shoulder strap near the side, a force that pulls the cup diagonally upward works, so that the rotational movement of the human body during movements such as walking and running can be effectively suppressed. The attachment position of the shoulder strap is the position within 3 cm in the X direction from the side end of the cup on the front side, and the midpoint between the back center and the side center (that is, the middle between the front center and the back center) on the back side. It is preferable that the position is within 5 cm from the side. Furthermore, since the shoulder strap portion pulls the front cup toward the rear surface side of the body, it also contributes to vibration isolation in the Z direction.

As described above, in addition to the sub-wing portion, the brassiere of the present invention has one of 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 as the vibration isolation portion. When having one or two or more, a special anti-vibration effect can be exhibited. In particular, by combining the anti-vibration effect in each of the X, Y or Z directions, the anti-vibration property can be further enhanced.

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, and the position considered to be the edge assumed from the bulge shape if it is unclear.

As described above, the sub-wing portion is joined to and attached to the fabric constituting the main body (also referred to as the body fabric in the present disclosure). Further, the upper edge high stress portion and / the lower edge high stress portion may also be configured as a reinforcing portion of the fabric different from the main body. Reinforcing parts made of a cloth separate from the body cloth of the main body have better vibration isolation properties than those provided on the body cloth by power switching or the like (that is, by adding strength or weakness of tensile stress). It has the advantage of.

With reference to FIG. 5, in a specific embodiment, when the brassiere is arranged so that the distance between the connection points P1 and P2 on the front center side between the shoulder strap portion and the cup portion is maximized, the cup portion of the shoulder strap portion is arranged. The area ratio of the portion 111 not covered with the brassiere constituent material is preferably 60% or more with respect to the area of the triangle T formed by connecting the front center side end points P1 and P2 and the front center lower end point P3 of the connecting portion. , 70% or more, more preferably 80% or more, and most preferably 100%. This triangle forms the so-called cleavage. When the above ratio is 60% or more, it is possible to prevent the valley from being hidden and realize good aesthetics. The brassiere of the present invention can have, for example, a specific shaking value as described below, which is achieved by having a specific anti-vibration portion. The brassiere of the present disclosure is advantageous in that it is excellent in vibration isolation even in a so-called open state in which the above ratio is 60% or more.

The brassiere of the present disclosure exhibits good vibration isolation by having a specific vibration isolation portion. Therefore, since the pressure applied to each part can be reduced to 50 hPa or less while suppressing the shaking of the chest, the maximum pressure applied to the present disclosure can be reduced to 50 hPa or less, and an unpleasant tightening feeling at the time of wearing can be avoided. In general, tightening is often done to suppress the shaking of the chest, and in particular, brassieres with extremely high shoulder pressure are occasionally found. However, when the pressure applied to each part of the brassiere exceeds 50 hPa, it generally tends to be unpleasant. In the present invention, since the movement of the chest in each of the X, Y, and Z directions is suppressed and dispersed, it is possible to prevent the concentration of pressure. In particular, the above-mentioned reinforcement of the shoulder strap portion is excellent in the effect of dispersing the pressure. The maximum pressure is more preferably 45 hPa or less, 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, still more preferably 15 hPa or more, from the viewpoint of suppressing displacement during wearing and suppressing shaking.

The material of each member of the brassiere of the present disclosure (that is, the member constituting the body cloth and the reinforcing portion) is not particularly limited, and synthetic fibers such as polyester fibers and polyamide fibers, and cellulose-based materials such as rayon, cupra, and acetate are used. 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 knitted fabrics, woven fabrics, non-woven fabrics and the like are used. Moreover, you may use the crimped fiber. In the present invention, it is effective to arrange a cloth having appropriate stretching characteristics on each member. In each member, a knitted fabric having an elongation in which polyurethane elastic fibers are interwoven is preferably used. Further, double circular knitting, tricot knitting, raschel knitting and the like can be used for the cloth of the cup and the wing part. The knitting gauge of the knitting machine used is preferably 20 to 40 GG. Further, a woven fabric or a warp knit is preferably used for the high stress portion, and a slightly stretched lace or the like using a jacquard knitting machine is excellent in design and is very preferably used.

Each member can be composed of monofilament or multifilament. The multifilament yarn includes a matting agent such as titanium dioxide, a stabilizer such as phosphoric acid, an ultraviolet absorber such as a hydroxybenzophenone derivative, a crystallizing nucleating agent such as talc, an easy lubricant such as Aerosil, and a hindered phenol derivative. It may contain an antioxidant, a flame retardant, an antistatic agent, a pigment, a fluorescent whitening agent, an ultraviolet absorber, an antifoaming agent and the like.

The total fineness of the fabric material constituting each member of the brassiere of the present disclosure can be in the range generally used for clothing and the like. Above all, from the viewpoint of strength and softness, the total fineness is preferably about 22 to 700 dtex.

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

Further, it is desirable that the fabric used for each member is subjected to a water absorption process.

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 use a three-dimensional knit for the cup to improve breathability.

The brassiere of the present disclosure is extremely excellent in vibration isolation. The following methods can be used to objectively evaluate the degree of shaking. Five subjects with a height of 160 cm ± 8 cm and a value of 17.5 cm or more (top bust size-under bust size) were made to wear bras, and the speed was 4.5 km / h on a treadmill, and the pace was 140 steps per minute. Then, when landing, make a treadmill so that one foot is off the ground. At this time, a reflecting sphere having a diameter of 1.3 cm is attached to the clavicle portion and the bust top portion, and the reflecting sphere is photographed with two high-speed cameras for 20 seconds. As an index of chest sway when sprinting so that the clavicle sway is about 7.0 cm, (bust top sway)-(clavicle sway) (cm) in 20 seconds (average of maximum values) -(Average of minimum values) (cm) is calculated in three directions of 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 perpendicular to the X direction, respectively. The largest value among the values in the three directions is the shaking (cm) when worn, and is divided by the value (cm) of (top bust dimension-under bust dimension) to obtain the shaking value. When the shaking value is 0.3 or less, the shaking is small, which is advantageous. The shaking value is preferably 0.25 or less, and more preferably 0.2 or less. The smaller the shaking value, the more preferable, but from the viewpoint of avoiding excessive pressure and easily obtaining a good wearing feeling, for example, it is preferably 0.03 or more, more preferably 0.05 or more.

In order to further objectively evaluate the degree of fine swaying of the chest in the cup in the present disclosure, the following methods can be used. When evaluating the chest sway of the appearance described above, a 3-axis accelerometer (SA12ZSCA: manufactured by Fuji Ceramics Corporation) was directly attached near the subject's bust top (which will be located inside the brassiere). At a speed of 4.5 km / h on a treadmill, at a pace of 140 steps per minute, make a short run so that one foot is off the ground when landing. In the measurement for 20 seconds at this time, the accelerations in the x direction (horizontal direction), the y direction (vertical direction), and the z direction (depth direction) are measured, and the accelerations in each direction (average of maximum values)-(average of minimum values) are measured. ) (M / s ² ) is calculated for each of the three directions. The lower the acceleration, the less the small shaking of the chest in the cup, and the smaller the value, the better. In particular, when it is 50 m / s ² or less, it is possible to suppress the fine vibration of the chest in the cup, and it is possible to reduce the discomfort during the wearing operation.

The following method is used to evaluate the bust volume. G is the point where the line connecting the left and right tops of the brassiere when wearing the brassiere and the line extending vertically from the thoracic stalk in the Z-axis direction (from the thoracic stalk to the brassiere direction) are orthogonal, and the distance from the thoracic stalk to the point G is bust. Measure as height. It is considered that the smaller this distance is, the smaller the bust volume in appearance is, and it is evaluated that the bust volume is suppressed.

Hereinafter, the present invention will be specifically described with reference to Examples. Of course, the present invention is not limited to these. The brassieres obtained in Examples and Comparative Examples were evaluated by the following methods.

A load of 0.5 (N) × cross-sectional area (mm ² ) was applied in the length direction of the shoulder strap, and the elongation (%) was measured. When the shoulder straps of the reinforcing portion were present, the elongations of the shoulder straps of the body cloth and the shoulder straps of the reinforcing portion were measured.
Grasp length of test piece: 10 cm
Stretching speed: 30 cm / min
The dough sample of each member was measured under the above conditions, but when the gripping length of the test piece could not be obtained, the length was appropriately changed. When the width of the test piece could not be obtained, the width was changed as appropriate and the measurement was performed.

(5) Shaking when worn Five subjects with a height of 160 cm ± 8 cm (top bust-under bust) and a brassiere size of 38DD (British size) (85E in Japanese size) were asked to wear the brassiere and speeded on a treadmill. At 4.5 km / h, at a pace of 140 steps per minute, I sprinted so that one foot was off the ground at the time of landing. (At this time, a reflective sphere with a diameter of 1.3 cm was attached to the clavicle and the bust top, and the reflective sphere was photographed with two high-speed cameras (250 frames / SEC) for 20 seconds. It was set to about 0 cm. As an index of chest sway when worn, (bust top sway)-(clavicle sway) (cm) in 20 seconds (maximum value average)-(minimum value average) (cm) ) Is calculated, and the value in the direction of the largest of the horizontal (X), vertical (Y), and depth (Z) values is taken as the shaking (cm) when worn, and is divided by (top bust-under bust) (cm). The results were calculated by averaging the results of 5 people.

(6) Accelerometer when wearing When measuring the shaking when wearing, a 3-axis accelerometer (SA12ZSCA: manufactured by Fuji Ceramics Corporation) is directly attached near the subject's bust top (which will be located inside the brassiere). As in the case of the above-mentioned shaking measurement test, the treadmill was used to make a short run at a speed of 4.5 km / h at a pace of 140 steps per minute so that one foot was off the ground at the time of landing. In the measurement for 20 seconds at this time, the accelerations in the x direction (horizontal direction), the y direction (vertical direction), and the z direction (depth direction) are measured, and the accelerations in each direction (average of maximum values)-(average of minimum values) are measured. ) (M / s ² ) was calculated for each of the three directions. The acceleration was calculated by averaging the results of five subjects in the values in each direction.

(7) Measurement of the appearance of the bust volume Refer to Fig. 12, the line connecting the left and right tops of the brassiere when wearing the brassiere and the line extending vertically from the bust stalk in the Z-axis direction (from the bust stalk to the brassiere direction). The points where are orthogonal to each other were defined as G, and the distance from the thoracic stalk to the point G was defined as the bust height.

(8) Maximum wearing pressure Using a multi-point contact pressure gauge (AMI3037-10) manufactured by AMI Techno Co., Ltd., when wearing a brassiere, the lower side tape part in the wing part, the center part of the wing part, and the center of the shoulder strap part A sensor is inserted between the wearer and the brassiere at the back of the shoulder strap, above the cup, below the cup, and below the cup to measure the pressure, and the maximum value obtained. Was defined as the maximum pressure (hPa).

The shortest distance when the brassiere was arranged so that the distance was the longest was 30 cm).

Use a urethane molded product with a thickness of 6 mm and a 10% vertical and horizontal average elongation stress of 3.0 N for the cup, and wrap the cup with a fabric of 28 GG two-way tricot knitted fabric of nylon 56 dtex polyurethane 44 dtex and 10% vertical and horizontal average elongation stress 0.4 N. , The cup portion 102 was produced. The 10% vertical and horizontal average elongation stress of the entire cup portion was 3.7 N. The same two-way tricot knitted fabric was used for the wing portion 103, and a Russell 1 cm wide tape having a vertical and horizontal average elongation stress of 1.7 N was used for the lower side tape.

The upper joint end of the cup is a point Q and a point P1 (that is, two points), the lower joint end of the cup is a point W (that is, one point), and further, from the point Q to the point W along the peripheral edge of the cup. The sub wing portion and the cup portion are joined over the entire extending line segment (therefore, the points P1 and W are the upper end and the lower end of the sub wing, respectively), and the back center from the bust top H. A sub-wing portion having a wing-side joint extending linearly from the upper side to the lower side of the sub-wing portion at a position of 80% of the total length of the line segment I toward C is provided with nylon 33 dtex and polyurethane 44 dtex and polyurethane as an insertion thread. It was formed by a power net consisting of 310 dtex. In this brassiere, as a result of setting m2 to 31 cm and m1 to 28 cm, E1 which is the elongation rate of the sub-wing portion when worn was 31.8%. The elongation stress σ of the sub wing portion at this elongation rate was 273 cN / inch. The Young's modulus ratio of the sub-wing portion and the wing portion, YR1 / YR2, was 1.19.
