Description

  The present invention relates to a brassiere that suppresses shaking of a chest during a wearing operation. More specifically, the present invention relates to a brassiere that has a non-wire type cup part and has an effect of suppressing chest shaking during a wearing operation without impairing comfort, that is, vibration proofing.

  Usually, there are a wire type and a non-wire type brassiere. In the wire type, the breast is supported by the wire provided around the lower part of the cup part, so that the correction function of the bust shape is given, but the hardness of metal or hard plastic generally used as a wire is It is expensive and it cannot be denied that the body is tightened at the time of wearing and the pain is felt due to the wire biting in. On the other hand, in the non-wire type which does not install a wire, it becomes possible to wear comfortably without tightening or biting of the wire. However, the correction function is inferior to the wire type for the bust shape correction.

One of the main purposes of a brassiere is to clean the shape of the chest, 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.
Furthermore, compared to the wire type, the non-wire type is not restrained by the wire, so the breast is more likely to flow from side to side and the shaking becomes larger than the wire type.

  In recent years, a non-wire type is preferred because of a comfortable wearing feeling, and there is a demand for a non-wire-type brassiere that has a formability and a function of suppressing shaking during operation.

  Based on the above, considering daily use, it is hoped to develop a brassiere that can be worn easily with less tightening while reducing the shaking of the chest during daily light exercise while maintaining a wide cleavage and maintaining aesthetics. It is rare.

  Patent document 1 arrange | positions the plate-shaped shaping | molding auxiliary | assistance part which has a curved surface with respect to a bust at least the lower part of a cup part, and does not give a wearer a feeling of pressure and a tightening feeling, but the bust shaping | molding property. Describes a bra that can be enhanced.

  In Patent Document 2, a non-stretchable or non-stretchable lift-up cloth is arranged on the front side of the cup part, and the upper end of the lift-up cloth is connected to the strap part so that the bust can be lifted and shaped at a high position. And a brassiere that can suppress the bust from flowing to the side by weight.

  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.

International Publication No. 2013/076873 Japanese Patent Laid-Open No. 2015-212437 JP, 2014-163018, A

  In the brassiere of Patent Document 1, by arranging a plate-shaped modeling auxiliary part having a curved surface with respect to the bust at least at the lower part of the cup part, the modeling auxiliary part is spread by the bust when worn, and by an elastic action By acting so that the bust is sandwiched by the returning force, the chest can be moved upward, and the bust molding ability can be improved. However, during operation, the bust is not firmly supported by the side, so that the bust escapes to the side due to movement, which is sufficient for suppressing the bust shaking during operation. I can't.

  In the brassiere of patent document 2, it becomes possible to bring the chest to the center by the effect of lifting the bust by the non-stretchable or non-stretchable lift-up cloth and the reinforcing member on the front side of the cup part, and the formability can be obtained. It becomes possible. However, although there is a force to pull up the bust, the force to suppress the chest is not sufficient on the ground contact surface between the side bra and the bust, so that a sufficient effect cannot be obtained with respect to the suppression of shaking during operation.

  In the brassiere of Patent Document 3, it is possible to suppress shaking during operation without sacrificing comfort while opening a cleavage gap greatly due to the effect of subwing. However, in the non-wire type of this brassiere, when pulling the chest to the trunk by sub-wing, there is no wire, so the fixing force is weak at the side, so the chest can not be fixed sufficiently and flows As a result, a sufficient anti-vibration effect may not be obtained.

  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, that is, an anti-vibration property, in a non-wire-type brassiere. It is to provide a non-wire type brassiere that excels in comfort.

  The inventors of the present invention have chest shakes in all directions during operation. In the wire-type bras shown in Patent Documents 1 to 3, the bra and the chest are in close contact with each other, and the left and right shakes. On the other hand, in the case of a non-wire type brassiere, the chest cannot be fixed sufficiently, and a gap is formed between the chest and the brassiere, especially at the side of the cup. It was found that a movable space was created and the left and right shaking increased. In addition, it has been found that the vertical shaking also increases with the left and right shaking. For this reason, in non-wire type brassieres, the gap between the chest and the brassiere is eliminated at the side part during operation so that the chest does not flow from side to side, so that it can suppress left and right shaking and vertical shaking. it is conceivable that.

  As a result of intensive studies and experiments conducted to solve the above-mentioned problems, the present inventors have found that in a brassiere having a reinforcing part in the cup part along the end of the cup from the joint part of the cup and the shoulder part, the physical properties of the reinforcing part By setting the value to a predetermined value, it was possible to suppress the movement of the chest to the side during operation, and it was found that the shaking of the chest during operation can be reduced, and the present invention has been completed. . Furthermore, in the present invention, it has been found that a high vibration suppressing effect can be obtained by having a predetermined vibration isolating portion in addition to the reinforcement of the cup portion. 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 provided with a shoulder strap connected to the cup part, the cup part having a reinforcing part arranged along the end of the cup from the joint part of the cup and the shoulder part, A brassiere having a rate of 1.0 × 10 ⁵ Pa to 1.0 × 10 ⁷ Pa and having a specific vibration isolator is provided. By making the cup reinforcement part and the specific vibration isolation part coexist, a higher vibration isolation effect can be obtained as compared with the case where only the cup reinforcement part is present.

  Referring to FIG. 1, a brassiere 100 according to one embodiment of the present invention includes a pair of cup portions 102 (one of the pair is shown in the figure) and a connection connecting the front center sides of the cup portions to each other. Part 101 and wing part 103 (which is arranged on the side of cup part 102 (that is, on the side of the wearer)). 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. Referring to FIG. 1, the cup reinforcing portion 104 is P <b> 1 at W <b> 1 (the shortest distance from the connection point P <b> 1 between the shoulder strap portion and the wing portion to the center side of the shoulder strap portion) that is a joint surface between the cup and the shoulder strap portion. From the shoulder strap to the center of the shoulder strap at a length of 50% or more of W1, contact the shoulder strap, and referring to FIG. 1, at least the junction from the lower end of the cup and wing along the cup edge from P1 A shape covering up to T1 is formed.

  In the bra of the present disclosure, the cup is assumed to receive 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, the “wearer side” means the back side of the brassiere (that is, the side where the cup has a concave shape), and the “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 circumference is maximized.

  In a particular aspect, the brassiere has a reinforcement in the cup portion that is disposed along the cup end from the cup-shoulder joint.

  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. Especially in a non-wire type brassiere with no wire at the end of the cup, there is no fixing force due to the wire, so that the chest is not sufficiently fixed. Further, during operation, it is assumed that a gap between the cup and the chest widens with the vibration of the chest. At this time, if the wire is present at the end of the cup, it is fixed at the end by the wire, thereby reducing the gap on the side of the cup and eliminating the space for the chest to flow. On the other hand, in the non-wire type, the above-mentioned fixing force cannot be sufficiently exerted, so in the side part, a space between the brassiere and the chest due to the movement of the chest during operation causes the chest to flow. Can be done. This phenomenon is considered to be the cause of large shaking during operation in the non-wire type.

  It is preferable that the cup reinforcing portion is disposed in the cup portion along the cup end portion from the joint portion between the cup and the shoulder portion. On the joint surface between the cup and the shoulder, W1 (the shortest distance from the connection point P1 between the shoulder strap and the wing to the center of the shoulder strap) is 50% of W1 from P1 to the center of the shoulder strap. In the above length, it is preferable to be in contact with the shoulder strap portion. When the shoulder strap is in contact with the shoulder strap at a length of 50% or more of W1, the force with which the shoulder strap pulls the chest is transmitted to the cup reinforcement, improving the adhesion between the cup and the chest. By reducing the space in which the chest moves, the movement of the chest can be suppressed.

  The cup reinforcing portion 104 preferably has a shape that covers at least the joining point T1 between the lower end of the cup portion and the wing portion along the cup end portion from P1. More preferably, it is desirable to arrange in a part covering from P1 to the cup lowest point T2 along the end of the cup. In addition to the effect of suppressing shaking by being placed in the part that covers up to T2 which is the lowest point of the cup, it is possible to lift the chest upward from the lower part of the cup by the reinforcement part joined to the shoulder strap part, A bust-up effect is also obtained.

  It is preferable that the width of the cup reinforcement 104 is arranged from 0.5 to 4.0 cm from the end of the cup connecting P1 to T1 or T2.

The Young's modulus of the cup reinforcement 104 is 1.0 × 10 ⁵ Pa to 5.0 × 10 ⁷ Pa, which is advantageous from the viewpoint of suppressing the shaking. The Young's modulus is preferably 5.0 × 10 ⁵ Pa to 1.0 × 10 ⁷ Pa. The Young's modulus in a general urethane cup is less than 1.0 × 10 ⁵ Pa. For this reason, when the Young's modulus of the cup reinforcing part is 1.0 × 10 ⁵ Pa or more, it is possible to sufficiently suppress the chest from flowing to the side during wearing and operation, and the chest during exercise Left-right movement (X direction) can be suppressed. In addition, it is possible to suppress vertical movement (Y direction) and forward / backward movement (Z direction) due to left-right movement. Moreover, since it is 5.0 * 10 < ⁷ > Pa or less, since a reinforcement part does not become hard too much, it becomes possible to suppress a shake, without impairing the comfort at the time of wear.

  In addition, the physical property values mentioned in the present disclosure are measured when the cup reinforcing part is composed of two or more layers (for example, two layers of urethane pad and fabric), and the tensile stress is measured in a state where two or more layers are stacked. To do.

The Young's modulus is specifically measured as the Young's modulus when stretched in the horizontal direction (for example, the direction of a straight line L1 in FIG. 3 described later) and the vertical direction (direction of 90 ° with respect to the horizontal direction). Is done. The Young's modulus is calculated from the relationship between the strain and the elongation stress of the fabric as described below after measuring the elongation stress of the fabric.
Young's modulus [Pa] = (fabric stretching load [N / mm] / fabric thickness [mm]) / (strain [-])
The above-mentioned stretching load refers to a 10% stretch stress in the warp 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 L106.88.12.1 A method and This is a value obtained by measuring a stress (N) when stretched in the horizontal direction by 10%. Using this value, the Young's modulus in the vertical and horizontal directions is calculated from the relationship between the thickness of the fabric and the strain according to the above formula.
Then, the value which averaged these is used as a Young's modulus in a cup reinforcement part. At this time, the value of the Young's modulus in the vertical direction / the Young's modulus in the horizontal direction, which is the ratio of the Young's modulus in the vertical direction and the horizontal direction, is preferably in the range of 0.1 to 10. By being in the above-mentioned range, a good wear feeling can be obtained by taking a vertical stress balance and making the cup easily fit on the chest.

  The physical property values mentioned in the present disclosure may be measured by grasping the end of each part of the brassiere unless otherwise specified, or may be measured by cutting out a fabric from each part. It is intended that the physical property value to be measured may be the value of the present disclosure.

  When the cup reinforcing portion is formed, a portion having a high tensile stress may be arranged at a predetermined position of the cup by changing the knitting structure and the used yarn denier. In addition, a method of sewing or adhering a reinforcing cloth to the inside of the brassiere (that is, the wearer's skin side) 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. .

  Note that the cup reinforcing portion of the present disclosure can further suppress the amplitude of the chest in each direction, in combination with a specific vibration isolating portion. In particular, when used together with the sub wing in the vibration isolator, it is possible to suppress the chest flowing to the side in the cup reinforcement, and to suppress and fix the chest in the trunk direction in the sub wing. A vibration effect is obtained.

  In addition to the above, by providing a sub-wing part, providing a high-stress part on the upper and / or lower edge of the cup, and providing a vibration isolating part on the shoulder strap part, it is possible to further suppress large external shaking. Is possible. The vibration isolator mentioned in the present disclosure indicates reinforcement to the sub-wing and the upper edge high stress part, the lower edge high stress part, and the shoulder strap part.

  In certain embodiments, the brassiere has an upper edge high stress portion (eg, upper edge high stress portion 105 in FIG. 1) that extends along the upper edge of the cup.

  In certain embodiments, the brassiere has a lower edge high stress portion (eg, lower edge high stress portion 106 in FIG. 1) that extends along the lower edge of the cup.

  With particular reference to FIG. 2, in a particular embodiment, the brassiere has a sub-wing 109 as a vibration isolator. By pulling the chest in the direction of the trunk of the body, the sub wing part improves the adhesion between the cup and the chest, is excellent in the effect of integrating them, and has the effect of preventing the chest from floating during operation.

  In a typical embodiment, the sub wing portion is overlapped on the main body of the region that is continuous over the region that is part of the cup portion and the region that is part of the wing portion. In a specific embodiment, the sub wing portion has a brassiere arranged so that the line segment I connecting the bust top H of each cup portion and the back center C of the corresponding wing portion is the longest, and is the same as the line segment. When a plane S having a normal to the direction is defined, the plane at a position of 0 to 25% from the bust top H on the line segment I toward the back center and the plane at a position of 55 to 100% On the upper side, there are joint portions (for example, the cup side joint portion 107aS and the wing side joint portion 107bS in FIG. 2) between the sub wing portion and the main body, and the sub wing portion is not joined to the main body. Have. In the present disclosure, the back center means a center point in the vertical direction of the wing portion fabric on a line corresponding to the back center of the wearer. For example, when the wing part has a hook part, the center of the back is defined with the hook part fastened. In the present disclosure, when the length adjustment mechanism is present in the wing portion with respect to the definition related to the shape or the dimension defined by using the “center of the back”, the spine defined at any one position of the length adjustment mechanism is provided. It should be noted that the above provisions should be satisfied with respect to the center.

  The subwing portion and the main body typically have the following two joint portions. The first joint portion is 0 to 25%, preferably 5 to 25%, more preferably 8 from the bust top H on the line segment I toward the back center C with respect to the plane S defined as described above. It exists on the plane at a position of ˜23%. When the position of the 1st junction part is 0% or more toward the back center from a bust top, a pulling force does not apply too much to a bust top, and a feeling of wear is good. On the other hand, when it is 25% or less, the force for pulling the bust toward the trunk of the body is easy to work, and high vibration isolation is obtained. The second joint portion is present on the plane at a position of 55 to 100%, preferably 55 to 95% from the bust top H on the line segment I toward the back center C with respect to the plane S described above. When the position of the second joint portion is 55% or more from the bust top toward the center of the back, a tensile force is easily applied to the bust top, and high vibration isolation is obtained. On the other hand, when the position of the joint portion is 100% or less from the bust top toward the center of the back, the force that draws the bust toward the trunk of the body is easy to work, and high vibration isolation is obtained.

  The junction between the sub-wing part and the main body relates to the plane S defined as described 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 55 to 55%. It may further exist in a part other than the plane at the position of 100%. However, from the viewpoint of obtaining a better anti-vibration effect by the subwing portion, with respect to the plane S, the plane at a position of, for example, more than 25% to less than 55% from the bust top on the line segment I toward the back center. It is desirable that there are no joints on the top.

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

  The subwing portion length is typically the length of a line segment La + Lb defined as described later. The length of the line segment Lb is preferably 20 to 90% of the length of the wing portion. A method for obtaining the length of the wing portion and the widths of La and Lb will be described below with reference to FIGS.

  A line segment L2 that defines the shortest distance from the straight line L1 drawn so as to be in contact with the lowermost end of the brassiere to the boundary point Pa between the cup upper edge and the cup side edge is assumed. Of the intersecting lines between the plane passing through the line segment L2 and perpendicular to the line segment L2 and the fabric surface of the main body (the outer surface as viewed from the wearer), the intersecting line having the maximum length in the cup region The intersection of the intersection line and the side edge of the cup is M1, and the intersection of the intersection line and the edge of the cup-side joint 107aS on the end side of the sub wing is M2, and M1 and M2 on the intersection line A line segment between the lines 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 end side of the sub wing. A line segment between M2 and M3 on the intersection line is defined as a line segment Lb.

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

  The length of the line segment L2 is suitably 5 cm to 25 cm.

  The sub wing portion length m1 is the shortest length in the fabric connecting M2 and M3 of the joint portion 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 a length m2 between the joint portions of the main body. A brassiere is usually worn in a stretched state of about 15-25%. The sub wing length m1, the length m2 between the joints in the main body, and the stress of the sub wing portion and the main body are preferably designed so as to realize a desired vibration isolation effect with a desired elongation rate.

E2 is the body elongation rate when worn here, that is, {(under bust size) / (peripheral length of brassiere) × 100} -100 (%), while the sub wing part gives the set stress. Assuming that the elongation percentage of the sub wing part is E1, the following formula:
(1 + E2 / 100) × m2 = (1 + E1 / 100) × m1
Where m1 is
m1 = {(1 + E2 / 100) × m2} / (1 + E1 / 100)
It is represented by

In a specific embodiment, as the fabric physical property of the sub wing part, it is desirable that the extension stress at the third extension in the 30% repeated extension test in the horizontal direction of the brassiere is 1.5 to 8.0N. If the tensile stress of the sub wing part is 1.5N or more, the desired stress can be obtained well, so that the anti-vibration effect is good, while if it is 8.0 N or less, the sub wing is not too tight and worn. Sometimes it does not get uncomfortable.
The above-described relationship between the tensile stress and the elongation rate is carried out in accordance with the cut strip method of JIS L10968.8.12.1 A method.

  The fabric of the sub wing part does not necessarily need to be stretched more easily than the fabric of the main body, and the length of m1 and m2 is adjusted according to the above formula according to the ease of extension of the sub wing part, thereby fitting the skin of the bra The effect is enhanced, and a tensile force is applied to the cup-side joint portion of the sub wing portion when worn, so that the anti-vibration effect can be exhibited. From the viewpoint of satisfactorily exhibiting the desired tensile stress, the lengths of m1 and m2 exceed ± 10%, ± 8%, or ± 5% from the design value determined by the above formula, respectively. It is preferable not to come off.

  The sub wing part greatly contributes to the vibration proofing property in the X and Z directions among the shakings in the X, Y and Z directions of the chest. That is, the subwing portion 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.

  By using the cup reinforcing portion 104 and the sub wing together, a sufficient anti-vibration effect can be obtained even in a non-wire type brassiere. As described above, the effect of the sub wing is that the chest is pulled toward the trunk, so that the gap between the cup and the chest can be eliminated, and the chest can be firmly fixed. However, when there is no wire, the fixation with the chest on the side is weak, so when pulling in the trunk direction by subwing, the chest moves to the side and the force to pull in the trunk direction is I can't fully demonstrate my breasts. In contrast, the presence of the cup reinforcement on the side of the cup suppresses the chest from flowing to the side by the reinforcement when the chest is pulled toward the trunk by the subwing. By this, it becomes possible to firmly improve the adhesion between the cup and the chest, and at the same time, it is possible to suppress the shaking of the chest.

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

  In another aspect, an anti-vibration effect can be achieved by providing a high stress portion on the upper edge 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 L1096.88.11 A method. 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 portion 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.

  When the ratio S2 / S1 is 2/1 or more, the effect of suppressing chest shaking 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-proof property in the X and Y directions 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 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 portion is disposed over the width of 0.5 to 5.0 cm on the upper portion of the cup portion. 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 a high stress part in the lower edge part of a 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 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 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 vibrations 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 5% to 50%. It is preferably 10% to 40%. When the ratio is 5% or more, the reinforcing effect is large, and even with a large cup, the chest shaking suppressing effect can be obtained satisfactorily. 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 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. Moreover, it is preferable that the extension stress of a center part is 0.5-50N, More preferably, it is 1-20N, More preferably, it is 1.5-15N, Most preferably, it is 2-10N. 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 aspect, 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) (eg, width W3 × thickness in FIG. 1) is calculated. It is the number average value of the cross-sectional area to be measured. 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 at a position 25 to 60%, more preferably 30 to 50% away from 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. 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 shakings of the chest in the X, Y, and Z directions. 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 for pulling the cup diagonally upward works, so that the movement of the human body during movement such as walking and running can be effectively suppressed. 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 has a cup reinforcing portion having predetermined physical properties in the cup portion, and the vibration isolating portion includes a sub wing portion, a cup upper edge high stress portion, and a cup lower edge high stress. In the case of one or a combination of two or more shoulder strap portions having a specific average cross-sectional area, particularly when a sub-wing portion is provided, a special anti-vibration 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 cup reinforcement portion and the sub wing portion with the upper edge high stress portion of the cup or the lower edge high stress portion or the shoulder strap portion of the cup, or two or more of these in the X, Y, and Z directions. It is possible to reduce and disperse the shaking, which is very preferable. 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 the preferable range of the characteristic values (particularly, the tensile stress ratio for the high stress portion and the average cross-sectional area of the shoulder strap portion) in each vibration isolation 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, but as described above, when the anti-vibration portion is provided in other parts, the average is 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.

  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 to be used is preferably 20 to 40GG. 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 constituting each member of the brassiere of the present disclosure can be in a range generally used in clothing and the like. Especially, it is preferable that a total fineness is about 22-700 dtex from a viewpoint of intensity | strength and softness.

Basis weight of the fabric used in each member of the bra is not particularly limited, about 50 to 500 g / ^{m 2} is preferred.

  Moreover, it is desirable to perform a water absorption process on the fabric used for each member.

  When using a urethane pad for a cup, although it does not specifically limit, a 2-15 mm-thick urethane pad is used suitably. 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 cup reinforcement part, By the cloth containing polyurethane elastic fibers, such as a cotton fabric, a polyester woven fabric, a polyamide material woven fabric, or a knitted fabric of a power net structure, a knitted fabric of a two-way structure, etc. Can be configured.

  The brassiere of the present disclosure is extremely excellent in vibration proofing. 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 speed is 5.5km / h on a treadmill and the pace of 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 shaking when the clavicle swing is about 7.0 cm, (bust top shaking)-(clavicle shaking) (cm) over 20 seconds (average of local maxima) -(Average of local 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 set as the shaking (cm) when worn, and is divided by the value (cm) of (top bust dimension−under bust dimension) to obtain the shaking value. 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 the non-wire type brassiere, the lateral movement during exercise tends to be larger than the wire type. For this reason, in the present disclosure, evaluation of the shaking value in the horizontal direction of the chest was performed together with the shaking value. As with the method of calculating the shaking value, the shaking value in the horizontal movement is (average of local maximum) over 20 seconds of (bust top shaking)-(clavicle shaking) (cm) in the horizontal direction- (local minimum value). (Average) of (cm). Then, it is divided by the value (cm) of (top bust dimension−under bust dimension) to obtain a horizontal swing value. The shaking value in the horizontal direction is preferably 0.20 or less, and more preferably 0.15 or less. The smaller the swing value in the horizontal direction, 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.

  Hereinafter, the present invention will be described specifically by way of examples. Of course, the present invention is not limited to these. In addition, the brassiere obtained by the Example and the comparative example was evaluated with the following method.

(1) Vertical and horizontal average stretching stress of the fabric of each member The stress of the fabric sample was measured in accordance with the cut strip method of JIS L10968.8.12.1 A method. For the 10% elongation stress characteristic, an arbitrarily set 10% elongation stress in the first direction and a 10% elongation stress in the second direction perpendicular to the first direction (per 2.5 cm width). The average value of these was calculated.
Specimen width: 2.5cm
Length of grip of test piece: 10cm
Elongation speed: 30 cm / min
Although the measurement was performed on the cloth sample of each member under the above conditions, the length was appropriately changed when the grip length of the test piece could not be taken. When the width of the test piece could not be taken, the width was changed as appropriate, and the obtained stress value was converted into a numerical value per 2.5 cm width.

(2) Young's modulus in the cup reinforcing portion Specifically, the Young's modulus of the cup reinforcing portion is determined in the horizontal direction (for example, the direction of a straight line L1 in FIG. ) Measured as the Young's modulus. The Young's modulus is calculated from the relationship between the strain and the elongation stress of the fabric as described below after measuring the elongation stress of the fabric.
Young's modulus [Pa] = (fabric stretching load [N / mm] / fabric thickness [mm]) / (strain [-])
The above-mentioned stretching load refers to a 10% stretch stress in the warp 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 L106.88.12.1 A method and This is a value obtained by measuring a stress (N) when stretched in the horizontal direction by 10%. Using this value, the Young's modulus in the vertical and horizontal directions is calculated from the relationship between the thickness of the fabric and the strain according to the above formula.
Then, the value which averaged these is used as a Young's modulus in a cup reinforcement part.

(3) Tensile stress and elongation of main body fabric In accordance with the cut strip method of JIS L10968.8.12.1 A method, the elongation up to 22.1N was measured, and the elongation corresponding to the set stress was obtained.

(4) Measurement of transverse direction stretching stress of sub wing part fabric The stretching stress of the stretch knitted fabric was measured by the following method.
Sample size: 100 mm in length (excluding gripping part)
Specimen width: 25 mm
Tensile tester: Tensilon tensile tester (RTC-1210A manufactured by Orientec Co., Ltd.)
Initial load: 0.1N
Pulling speed: 300mm / min
Tensile length and measurement: Stretched to 30% stretch, stretched at the same speed, then returned to its original length (recovered), and stretched and restored under these conditions three times, stretching stress value at the third stretch of 30% Asked.

(5) Elongation of shoulder strap portion In accordance with the cut strip method of JIS L10968.8.12.1 A method, the stress characteristic during stretching of the shoulder strap portion was measured. 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. In addition, when the shoulder strap of the reinforcement part exists, the elongation of each of the shoulder strap part of the body cloth and the shoulder strap of the reinforcement part was measured.
Length of grip of test piece: 10cm
Elongation speed: 30 cm / min
Although the measurement was performed on the cloth sample of each member under the above conditions, the length was appropriately changed when the grip length of the test piece could not be taken. When the width of the test piece could not be taken, the width was appropriately changed for measurement.

(6) Shaking at the time of wearing Height: 160cm ± 8cm (top bust-under bust) Bra size by 38DD (British size) 5 subjects wear the brassiere, speed treadmill 6.0km / h, At a pace of 150 steps per minute, a small run was performed so that one foot was away from the ground when landing (or a speed of 5.5 km / h, a pace of 150 steps per minute). At this time, a reflection sphere having a diameter of 2.0 cm was attached to the clavicle portion and the bust top portion, and the reflection sphere was photographed with two high-speed cameras (200 frames / SEC) for 20 seconds. The shaking of the clavicle portion was about 13 cm. As an index of chest shaking at the time of wearing, calculate (average of local maximum)-(average of local minimum) (cm) in 20 seconds of (bust top shaking)-(clavicle shaking) (cm), Of the horizontal (X), vertical (Y), and depth (Z) values, the value in the largest direction is taken as the shaking (cm) when worn, and the value is divided by (top bust-under bust) (cm). did. The results of 5 persons were averaged.
Also, among the various shakings, regarding the shaking in the horizontal direction (X), in addition to the overall shaking value, the shaking value in the horizontal direction is also (the shaking of the bust top in the horizontal direction)-(the shaking of the collarbone) (cm) 20 Calculate (average of local maximum)-(average of local minimum) (cm) in seconds, and calculate the amount of horizontal movement, and (top bust-underbust) (cm) divided by horizontal direction did.

(7) Maximum wearing pressure Using the multi-point contact pressure gauge (AMI3037-10) manufactured by AIM Techno Co., Ltd., when wearing a brassiere, the lower tape part in the wing part, the wing part center part, and the shoulder center part of the shoulder strap part , Shoulder strap rear side root, cup upper, cup side, and cup lower, insert a sensor between the wearer and the brassiere to measure the pressure, and the maximum value among the obtained values Was the maximum pressure (hPa).

(8) Comfortability and shaking feeling Comfortability Evaluation was made according to the following criteria during the wearing test of (6), and the evaluation of the monitor was averaged.
