Description

  TECHNICAL FIELD The present invention relates to a bra that suppresses chest sway in the wearing operation. More particularly, the present invention relates to a bra having a chest swing suppressing effect during wearing operation, i.e., an anti-vibration property, without losing comfort.

  One of the main purposes of brassieres is to make the chest shape clean, but one of the major roles is to suppress chest swings during exercise. However, even when wearing a bra, when walking or running, the chest often shakes greatly. In particular, when the size of the chest is large, the shaking becomes very large, causing discomfort and burden on the wearer, as well as causing the chest to drop. As a method of reducing the swing, a method of putting on a bra with a strong wearing pressure is effective, but in this method, the wearing comfort is significantly deteriorated. In addition, during exercise, the chest swings in particular become even greater, and problems such as interference with the wearer's movement and burden become more apparent. For this reason, a large number of sports bras have been developed as bras that reduce chest swing during exercise (Patent Documents 1 and 2). However, sports bras have a large covering area and many designs that cover the valleys of the chest in order to suppress shaking during exercise. For this reason, they lack aesthetics and often do not like daily use.

  For this reason, in consideration of daily use, it is desirable to develop a bra that has a large chest gap and maintains aesthetics, reduces chest sway during daily light exercise, and provides adequate wearing pressure. ing.

  Patent Document 3 includes a pair of cups, a connecting portion for connecting front center sides of the cups to each other, a wing, and a shoulder strap having an end connected to the pair of cups and the wing. In the bra, the cup portion has at least a pad, and the pad is a pad high stress portion extending along the pad upper edge or the pad lower edge, or both of the pad stretches the bust top portion of the pad A bra is described having a pad high stressed portion wherein the ratio S2 / S1 of the tensile stress S2 of the pad high stressed portion to the stress S1 is 2/1 to 80/1.

  In the technique described in Patent Document 3, the sub-wings are disposed on the bra body in the region extending from the cup to a part of the wings. By arranging the sub wing made of the fabric of the main body and the cloth fabric different in tensile stress, the tensile stress difference between the main body fabric and the sub wing when worn causes the joint portion of the sub wing portion in the cup portion to face the wing portion A pulling force is exerted to make the anti-vibration effect appear.

  In the above-mentioned bra, by the effect of the sub wing, it is possible to suppress the shaking at the time of operation without impairing the comfort while opening the valley of the chest widely. However, although the subjective evaluation of the feeling of swing and comfort when wearing this bra is improved as compared with a normal bra and the swing value is also reduced, some discomfort may be caused in terms of comfort. was there.

  Therefore, the problem to be solved by the present invention is to provide a bra that is excellent in the chest swing reduction effect during exercise, that is, the vibration damping property, preferably, in addition to the vibration damping property, the bra is also excellent in comfort. To provide.

  The present inventors actually use an accelerometer to measure that the bust is finely shaking in a three-dimensional direction in the cup even in a product such as the bra shown in Patent Document 3 in which the shaking of the entire bust is suppressed. It was found by the measurement used. In terms of acceleration, the product that is suppressing the shaking of the whole bust is suppressing the large shaking of the chest, but the acceleration due to the fine vibration is generated in all directions, and the chest always receives the impact due to the acceleration. It will be. It is thought that this is the cause of the feeling of incongruity although the shaking at the time of wearing is settled. For this reason, in order to further improve the wearing comfort, it is considered necessary to reduce the occurrence of this acceleration.

  The present inventors earnestly researched in order to solve the above-mentioned subject, as a result of repeating experiments, in the brassiere which has an opening and a specific vibration isolation part, the physical property of the connection part which connects a cup part is made into a predetermined value. Thus, the inventors have found that acceleration during operation can be suppressed without increasing the applied pressure, and the present invention has been completed. That is, the present invention is as follows.

Hereinafter, examples of typical aspects of the present invention will be described in detail.
One aspect of the present disclosure includes a pair of cups, a connecting portion connecting the front center sides of the cups to each other, a wing adjacent to the side of the cups, and an end having the pair of cups and the wings A bra having a shoulder strap portion connected to the portion, the extension stress at the third extension in the lateral direction 10% cyclic extension test of the connection portion being 10N to 30N, and having a specific anti-vibration portion Provide a bra. By combining the connection portion and the specific vibration isolation portion, a higher vibration isolation effect can be obtained as compared with the case where only the connection portion is present.

  Referring to FIG. 1, a brassiere 100 according to one aspect of the present invention includes a pair of cups 102 (in the figure, one of the pair is shown as a region surrounded by a dotted line), and a front of the cup It includes a connecting portion 101 which connects the center sides to each other, and a wing portion 103 (which is disposed on the side of the cup portion 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 a bra lower end. Wings 103 extend towards the back of the wearer. The wing 103 can have a base and a lower side (e.g., a tape). Each member is made of fabric. The brassiere further comprises a shoulder strap 110 whose end is connected to the wing 103 and the pair of cups 102.

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

  In the present disclosure, the "wearer side" intends the back side of the bra (i.e. the side where the cup is concave), and the "outside" means the opposite side to the wearer side.

  In the present disclosure, the “horizontal direction” (for example, the horizontal direction of the connecting portion) referred to in relation to the bra is the arrangement direction of the two cups, specifically, the bust top positions of the two cups are most separated from each other When you put the bra on, intended the direction of the straight line connecting the two bust top position. In the present disclosure, the “vertical direction” of the bra is the direction perpendicular to the above-described lateral direction, and is intended to correspond to the vertical direction of the wearer's body.

  In the present disclosure, "bust top position" intends a position corresponding to the wearer's bust top (i.e., a position corresponding to the wearer's nipple) when the bra is worn. The bust top position is the top of the cup's bulge shape (convex shape). In the present disclosure, the “front center line” and the “back center line” of the bra are lines extending in the longitudinal direction of the bra through the midpoint of the line 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 bra refers to the shortest length of a line drawn from the front centerline to the front centerline from the front centerline to the front centerline in the main body In the case of having the length adjustment mechanism 106) in FIG. 4, the value in a state where the length adjustment mechanism is adjusted so that the circumferential length is maximized is intended.

  In the present disclosure, the extension stress at the third extension in the 10% cyclic extension test of the connecting part 101 connecting the front center sides of the cup parts to each other is 10N to 30N. Furthermore, in the brassiere of the present disclosure, by combining one or more specific vibration isolation parts in addition to the main connection part, it becomes possible to suppress fine vibrations during operation, and the load during operation on the body can be reduced. It can be reduced and can have high comfort.

  It is usually assumed that the cup receives the wearer's breast. However, in fact in the cup, the chest is not completely along the cup and is not fixed. For this reason, when the chest shakes at the time of operation, it is considered that the chest has a small vibration in the cup. This fine vibration occurs in any direction in the X, Y, and Z directions even if chest vibration does not occur in appearance. This is because when the bra is worn and stretched in the horizontal direction when worn, the stretching force in the horizontal direction from the extension of the wing acts, and the material of the cup connecting portion is stretched. For this reason, it is thought that a connection part floats and a crevice will occur between skins. It is thought that the fixing force of the cup is reduced by the generation of this gap, an area where the cup and the chest are not installed near the front of the cup, that is, an area where the chest can escape is generated. Be For this reason, it is presumed that this phenomenon is the cause of feeling a feeling of shaking and a sense of incongruity even when a large shaking does not occur in appearance when worn.

  It is advantageous from the viewpoint of suppressing the above-mentioned fluctuation that the extension stress at the third extension in the 10% cyclic extension test of the connecting part is 10N to 30N. The tensile stress is preferably 15N to 25N. When the extension stress is 10 N or more, the connection portion is difficult to extend, and the connection portion becomes a fixing point, so that the chest can be fixed from the front surface to the side surface of the cup without floating the connection portion. Vibration can be suppressed. Moreover, since it is not hard at the time of wear that it is 30 N or less, it becomes possible to suppress a shake, without impairing comfort.

  Specifically, the tensile stress in the lateral direction is measured as a stress when each component is stretched in the horizontal direction (for example, the direction of the straight line L1 in FIG. 3 described later). Elongation and extension stress of this indication are a value measured based on a cut strip method tension test of JIS L1096.8.12.1 A method, unless otherwise specified.

  The physical property values referred to in the present disclosure may be measured by grasping the end of each part (for example, connection part) of the bra, unless otherwise specified, or the cloth may be cut out from each part to be measured. It is intended that the physical property value measured by any method should be the value of the present disclosure.

  By providing the sub wing portion, providing the cup upper edge and / or lower edge high stress portion, and providing the shoulder strap portion with the anti-vibration portion, it is possible to suppress the large shaking on the appearance and at the same time the body of the chest. The synergetic effect with the effect of attracting to the trunk makes it possible to further suppress fine shaking by closely adhering the cup and the chest.

  In certain embodiments, the bra has an upper edge high stressed portion (eg, upper edge high stressed portion 104 in FIG. 1) extending along the upper edge of the cup.

  In certain embodiments, the bra has a lower edge high stress portion (eg, lower edge high stress portion 105 in FIG. 1) extending along the lower edge of the cup.

  With particular reference to FIG. 2, in certain embodiments, the bra has sub-wings 109 as anti-vibration portions. The sub wing portion stretches from the cup portion to the wing portion by wearing, and by pulling the chest in the trunk direction of the body, the adhesion between the cup and the chest is enhanced, and these are integrated. It has an effect of preventing chest floating during operation. This makes it possible to suppress large shaking on the appearance during operation.

  In an exemplary embodiment, the sub-wings are superimposed on the body of the continuous region over the area that is part of the cup and the area that is part of the wings. In a specific aspect, the sub wing portion arranges the bra 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 identical to the line segment Defining a plane S having a direction normal, the plane on the plane at a position of 5 to 25% and a plane at a position of 55 to 100% from the bust top H on the line segment I toward the back center The junction between the sub wing and the main body (for example, the cup side joint 107aS and the wing side joint 107bS in FIG. 2) is present, and the sub wing is not joined to the main body. Have. In the present disclosure, the back center means a point on the line in the vertical direction of the wing portion fabric on the line corresponding to the back center of the wearer. For example, when the wing has a hook, the back center is defined with the hook held. In the present disclosure, with respect to the definition regarding the shape or dimension defined using “back center”, the back defined in any one position of the length adjustment mechanism when the length adjustment mechanism exists in the wing portion It should be noted that the above provision should be fulfilled with respect to the center.

  The sub wing portion and the body typically have the following two junctions. The first joint is 5 to 25%, preferably 8 to 25%, and more preferably 10 from the bust top H on the line segment I to the back center C with respect to the plane S defined as described above. It lies on the plane of ̃23% position. When the position of the first joint is 5% or more from the bust top toward the back center, the bust top is not excessively pulled, so the wearing feeling is good. On the other hand, if it is 25% or less, the force to draw the bust in the direction of the trunk of the body is easy to work, and high vibration isolation can be obtained. The second junction is on the plane at a position of 55 to 100%, preferably 55 to 95%, from the bust top H on the line segment I to the back center C with respect to the above-mentioned plane S. When the position of the second joint is 55% or more from the bust top toward the back center, the bust top is easily subjected to a tensile force, and high vibration isolation can be obtained. On the other hand, when the position of the junction is 100% or less from the bust top toward the back center, a force to draw the bust toward the trunk of the body is easily exerted, and high vibration isolation can be obtained.

  The junction between the sub wing portion and the main body is on the plane at a position of 5 to 25% from the bust top H on the line segment I to the back center C with respect to the plane S defined as described above. It may further be present at a site other than the plane at the 100% position. However, from the viewpoint of better obtaining the vibration damping effect by the sub wing portion, the plane S is located, for example, at a position of more than 25% to less than 55% from the bust top to the back center on the line segment I. It is desirable that there is no junction on top.

  The area of the region of the sub wing portion which is not bonded to the main body, out of the area of the region which receives tensile force when worn, is preferably 30% or more, more preferably 60% or more from the viewpoint of obtaining a good vibration damping effect. And 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 98% or less .

  The sub wing 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. The length of the wing and how to determine the width of La and the width of Lb will be described below with reference to FIGS. 3 and 4.

  A line segment L2 which defines the shortest distance from the straight line L1 drawn so as to touch the lower end of the bra to the boundary point Pa between the cup upper edge and the cup side edge is assumed. Of the intersection line 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 seen from the wearer), Select the intersection of the intersection line and the cup side edge as M1, and make the intersection of the intersection line and the edge on the sub wing end side of the cup side joint 107aS as M2, M1 and M2 on the intersection line Let the line segment between them be the line segment La. An intersection point between the intersection line and the edge on the sub wing portion end side of the wing side joint portion 107bS is M3. A line segment between M2 and M3 on the line of intersection is taken as a line segment Lb.

  The length of the wing refers to the area from M1 to the back end of the wing (boundary with the hook if the hook has a hook at the end of the wing, or to the back center C when worn if it does not have the hook) Means the shortest length of

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

  The sub wing length m1 is the shortest length in the fabric connecting 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 taken as the length m2 of the joint between the main body. Bras are usually worn with 15 to 25% stretched. The sub-wing length m1, the inter-joint length m2 in the body, and the stress of the sub-wing portion and the fabric of the body are preferably designed to achieve a desired anti-vibration effect at a desired elongation rate.

The body elongation rate at the time of wearing here, that is, {(under bust size) / (peripheral length of lowermost part of bra) × 100} −100 (%) is E2, while the sub wing portion gives a set stress. Assuming that the sub wing portion elongation rate for this is E1, the following formula:
(1 + E2 / 100) × m2 = (1 + E1 / 100) × m1
And m1 is
m1 = {(1 + E2 / 100) × m2} / (1 + E1 / 100)
Is represented by

In a specific aspect, as the material properties of the sub-wing portion, it is desirable that the extension stress at the third extension in the 30% cyclic extension test in the lateral direction of the bra be 1.5 to 8.0 N. If the extension stress of the sub wing portion is 1.5 N or more, the desired stress can be obtained well, so the vibration proofing effect is good, while if it is 8.0 N or less, the sub wing is not too tight, and the wear is worn Sometimes not offensive.
The above-mentioned relationship between the tensile stress and the elongation is carried out in accordance with the cut strip method of JIS L1096.8.12.1 A method.

  The fabric of the sub wing does not have to stretch more easily than the fabric of the main body, and by adjusting the lengths of m1 and m2 according to the above-mentioned formula according to the ease of extension of the sub wing, the fit to the bra's skin The effect is enhanced, and a tensile force is applied to the cup-side joint portion of the sub wing portion at the time of wearing, so that the anti-vibration effect can be exhibited. In addition, from the viewpoint of exerting desired tensile stress well, the lengths of m1 and m2 are respectively ± 10%, or ± 8%, or ± 5% from the value of the design determined by the above equation It is preferable not to remove it.

  The sub wing portion greatly contributes to the anti-vibration property particularly in the X and Z directions in the X, Y and Z directions of the chest. That is, the sub wing portion is excellent in the effect of enhancing the adhesion between the cup and the chest to integrate them, and has the 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 by the anti-vibration property in the Z direction, and the effect of preventing the chest extrusion is the anti-vibration property in the X direction where tension is particularly applied. More effectively.

  The sub wing portion pulls the cup in the oblique backward direction (corresponding to the combined direction of the X direction and the Z direction), thereby attracting the chest in the trunk direction, thereby enhancing the adhesion between the cup and the chest. However, at the same time, the chest tends to be drawn to the side as compared to a bra without a sub wing. For this reason, at the same time, in the connecting portion, the tensile force caused by the sub wing is stretched by being pulled in the left and right direction. For this reason, in the vicinity of the connection portion (center of chest), a gap is easily formed between the cup and the chest as compared with the bra without the sub wing. At this time, in the brassiere having the sub wing portion, the connecting portion has a predetermined stress, whereby the connecting portion becomes a fixing point, and a tensile force is generated to draw the chest closer to the trunk, and the connecting portion floats. It becomes possible to suppress, and it becomes possible to control fine shaking at the time of operation.

  The sub wing portion can be constituted by a fabric such as a cotton fabric or a polyester woven or knitted fabric having a smaller elongation than the main fabric, or a fabric having a greater elongation than the main fabric such as a knitted fabric of the power net structure. When the joining portion of the sub wing portion to the main body is both ends of the cup portion side and the wing portion side, the cloth for the main body and the fabric for the sub wing portion are overlapped at both ends of the cup portion side and the wing portion side The sub-wings can be formed by welding, or by other means.

  In another aspect, the anti-vibration effect can be exhibited by disposing the high stress portion at the upper edge of the cup. The upper edge high stress portion is disposed extending along the cup upper edge. 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 of the upper edge high stressed part S2 to the extension stress S1 of the central part is preferably 2/1 to 400/1. In the present disclosure, the central portion of the cup means a region including the top portion of the cup (i.e., the position corresponding to the top portion of the wearer's bust) and having a single tensile stress. In the present disclosure, the extension stress means a stress at the time of stretching by 10% in a longitudinal direction of the fabric in accordance with a cut strip method tensile test according to JIS L1096.8.12. 1 A method (N / 2.5 cm width, hereinafter simply referred to as N). Note) and stress in the 10% stretching direction (N) are measured, and the average value of these (hereinafter, also referred to as the horizontal and vertical average stretching stress, or simply stretching stress).

  When a cup part is comprised from two or more layers (for example, two layers of a urethane pad and a fabric), an extension stress is measured in the state which accumulated two or more layers.

  When the ratio S2 / S1 is 2/1 or more, the effect of suppressing chest sway by the high stress portion is large. On the other hand, if the ratio S2 / S1 is equal to or less than 400/1, the tensile stress in the high stressed part is not too high, and it is possible to prevent the bra from becoming hard and hard 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 proofing of the X, Y, Z directions of the chest, particularly in the X and Y directions. When walking or running, the chest placed in the cup moves up and down with some delay to the vertical movement of the human body. In this case, the upward movement 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 at the time of the action of walking, running, etc., the horizontal movement which rotates the body occurs simultaneously. Furthermore, when the upper edge high stress portion is provided to extend along the cup upper edge, the upper edge high stress portion can usually be attached slightly obliquely to the horizontal direction. This makes it possible to suppress the inward shaking of the chest due to the lateral movement, that is, the shaking in the X direction.

  The upper edge high stress portion is preferably disposed over the width of 0.5 to 5.0 cm at the top of the cup portion. The width is more preferably 1.0 to 4.0 cm. Moreover, the said width can be designed arbitrarily. For example, the width of the upper edge high stress portion can be designed to be thinner at the front center side of the wearer's body of the cup portion and to be thicker at the side.

  Moreover, in another aspect, the anti-vibration effect can be exhibited by arranging the high stress portion at the lower edge portion of the cup. The lower edge high stress portion is disposed extending along the lower edge of the cup portion. The lower 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 S3 / S1 of the extension stress of the lower edge high stressed part S3 to the extension stress S1 of the central part is preferably 2/1 to 400/1. When S3 / S1 is 2/1 or more, the effect of suppressing chest sway by the high stress portion is large. On the other hand, if the ratio S3 / S1 is 400/1 or less, the tensile stress in the high stressed part is not too high, and it can be avoided that the bra becomes hard and hard 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 proofing property particularly in the Y direction among the shaking in the X, Y and Z directions of the chest. When walking or running, the chest placed in the cup moves up and down with some delay to the vertical movement of the human body. In this case, it is possible to effectively suppress the chest swaying like hitting downward by providing the lower edge high stress portion.

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

  When both the upper edge high stress portion and the lower edge high stress portion are provided, the ratio of the sum of the area of the upper edge high stress portion and the lower edge high stress portion to the area of the entire cup portion is 10% to 50%. Is preferably 20% to 40%. When the ratio is 10% or more, the reinforcing effect is large, and even with a large cup, the chest sway suppressing effect can be favorably obtained. 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 tensile 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 still more preferably 100 to 350 N. When the said extension stress is 20 N or more, the reinforcement effect is large, and when it is 500 N or less, the discomfort at the time of wear can be avoided favorably. The tensile 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 stretching stress is 0.5 N or more, tearing or the like is less likely to occur during wearing and washing, and when it is 50 N or less, discomfort during wearing can be favorably avoided.

  When forming the upper edge high stressed portion and / or the lower edge high stressed portion in the cup portion, even if a portion with high tensile stress is disposed at a predetermined position of the cup by changing the knitting structure and the used yarn and denier. Good. Also, a method may be used in which a reinforcing cloth to be the upper edge high stress portion or the lower edge high stress portion is sewn or adhered to the inside of the bra (that is, the wearer's skin side). Or when using a urethane pad for a cup, when molding processing a urethane pad, you may use the method etc. which raise the rigidity of a part of pad by inserting textiles etc. which become a high stress part etc. .

In a specific aspect, the shoulder strap as the antivibration portion has an average cross-sectional area of 20 to 120 mm ² . In this case, the vibration isolation can be satisfactorily achieved. 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) × the thickness of the shoulder strap (mm). The average cross-sectional area is a number average value of cross-sectional areas measured at both ends of the shoulder strap portion and each portion obtained by equally dividing 10 between them. Specifically, the average cross-sectional area can be calculated as follows.

  Referring to FIGS. 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 (that is, the root portion) of the cup portion side (ie front side) of the shoulder strap portion. Cross-sectional area, the cross-sectional area calculated by the width W2 × thickness (not shown) of the end (that is, the root) of the wing side (ie, rear side), and the end of the cup side and the wing side Calculated by width × thickness (not shown) (for example, width W 3 in Fig. 1) of each cross section (that is, nine cross sections) that divides the distance between the end and the shoulder strap into 10 equal parts in the length direction The cross-sectional area of the The width W1 and the width W2 mean the shortest distance from the side connection points P1 and P2 of the shoulder strap portion to the cup portion and the wing portion, respectively, to the center side of the shoulder strap portion. In addition, when the adjuster which adjusts the length of the shoulder strap is provided, the length of the adjuster is made maximum and it measures.

The weight of the chest is large on the shoulder straps, and particularly in the case of a large cup size, the power becomes very large. Therefore, in the case of the bra of a sports bra and a cup size, the device which enlarges the width | variety of a shoulder strap part is carried out. However, when the width of the shoulder strap is wide, the sexyness is lost and the esthetics are inferior. Even when the width of the shoulder strap portion is narrow, by increasing the cross-sectional area of the shoulder strap portion, it is possible to absorb vibrations and stably support the cup portion. 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 greater than 120 mm ^2, but when the width is increased, aesthetics are impaired, and when the thickness is increased, the sound of the skin and outer ring Tend to be a problem. However, if reinforcement is applied to other parts of the bra as described above, the braille's excellent anti-vibration properties can be maintained if the average cross-sectional area of the shoulder strap is set to, for example, about 80% or more of 20 mm ² it can. For example, in the case of providing one or more of the upper edge high stress portion, the lower edge high stress portion, and the sub wing portion, the average cross-sectional area of the shoulder strap portion can be 16 mm ² or more and 120 mm ² or less.

  The dorsal connection center of the shoulder strap portion is located at a distance of preferably 25 to 60%, more preferably 30 to 50%, of the length of the wing portion from the back center of the wing portion toward the cup portion side. When the gap from the center of the back of the wing portion to the center of the back of the shoulder strap portion is 25% or more, there is an advantage of excellent vibration resistance, and when it is 60% or less, the shoulder strap portion is less likely to slip off There is. The length of the wing is defined as described above. Further, with the back side connection center of the shoulder strap portion, a vertical line drawn from the middle point of the line segment having the width W2 to the line segment forming the length of the wing portion in FIG. 4 and a line forming the length of the wing portion Means the point of intersection with the minute.

The elongation (power) of the shoulder strap portion is measured at a load elongation of 0.5 N / mm ^{2 in} the length direction, preferably 30 to 80%, and more preferably 40 to 70%. . Elongation can be measured based on the cut strip method tensile test of JIS L1096.8.12. 1 A method, but the entire shoulder strap part is a grip distance, and the load of measurement is the load of 0.5N multiplied by the average cross-sectional area I assume. If the power of the shoulder strap portion is 30% or more, it does not become 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 vibration can be favorably absorbed.

  The shoulder strap portion 110 preferably has a low stress portion having a tensile stress smaller than that of other portions. By providing such a low stress portion, concentration of applied pressure can be prevented and comfort can be enhanced. 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 110a.

  The shoulder strap greatly contributes to the vibration-proof property particularly in the Y direction among the shaking in the X, Y, Z directions of the chest. Vertical movement of the human body occurs when walking, running, etc., and with some delay, the vertical movement of the chest housed in the cup occurs, but the cup is supported from above by the shoulder strap having a certain cross-sectional area or more Thus, it is possible to suppress the vertical movement of the chest. Furthermore, by attaching the shoulder strap portion not near the center but near the side, the vibration resistance of the chest in the X, Y, and Z directions also greatly contributes to the anti-vibration property in the X direction. By attaching the shoulder strap portion near the side, a force to pull the cup obliquely upward is exerted, so that the rotational movement of the human body during the operation such as walking or running can be effectively suppressed. As for the attachment position of the shoulder strap part, the front side is a position within 3 cm approximately in the X direction from the side end of the cup, and the rear side is the middle point between the back center and the side center (ie, the middle between the front center and back center) A position within 5 cm on the side is preferred. Furthermore, since the shoulder strap portion pulls the front cup toward the rear surface side of the body, it also contributes to the anti-vibration property in the Z direction.

The bra of the present invention, as described above, uses a member having predetermined physical properties in the cup connection portion, and the vibration-proof portion includes the sub wing portion, the upper edge high stress portion of the cup, the lower edge high stress portion of the cup And, in the case of a combination of one or more of the shoulder straps of a specific average cross-sectional area, particularly in the case where the sub-wings are provided, a special anti-vibration effect can be exhibited. In particular, by combining the vibration isolation effects in the respective X, Y or Z directions, the vibration isolation can be further enhanced. For example, the combination of the connecting portion and the sub wing portion with the upper edge high stressed portion of the cup or the lower edge high stressed portion of the cup or the shoulder strap portion or a combination of two or more of them shakes in the X, Y and Z directions. Can be reduced and dispersed, and is very preferable. Also, in the case where the anti-vibration 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 of a specific average cross-sectional area It is also possible to reduce the lower limit of the preferable range of the characteristic value (in particular, the above-mentioned tensile stress ratio for the high stress portion and the average cross-sectional area of the shoulder strap portion) by about 20%. For example, when the average cross-sectional area of the shoulder strap portion is 20 to 120 mm ² , good vibration isolation can be obtained, but as described above, the average when the vibration isolation portion is provided at other portions Good vibration isolation can be 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 shape alone may define the boundaries between the members. In the latter case, in particular the outer edge of the cup part is defined as the position of the edge if the edge of the cup's bulge is clear, or the position considered as the edge assumed from the bulge shape if unclear.

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

  The body fabric may be formed of separate fabrics, or may be formed of a continuous fabric, and the shape alone may define boundaries between members. 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 cup's bulge is clear, or the position considered as the edge assumed from the bulge shape if unclear.

  Referring to FIG. 5, in a specific embodiment, when the bra is arranged such that the distance between the cup portion front center point Q1 and Q2 of the shoulder strap portion is maximum, the cup portion front center side end point Q1 of the shoulder strap portion , Q2 and the front center lower end point Q3 of the connecting part are preferably 60% or more, and 70% or more of the area ratio of the portion 111 which is not covered with the bra component material with respect to the area of the triangle T formed. Some are more preferable, 80% or more is more preferable, and 100% is most preferable. This triangle forms the so-called part of the valley of the chest. When the ratio is 60% or more, good aesthetics can be realized by preventing the valley from being hidden. The bra of the present invention can have a specific swing value as described below, which is achieved, for example, by having a specific anti-vibration portion. The brassiere of the present disclosure is advantageous in that it is excellent in anti-vibration even in the so-called open state where the ratio is 60% or more.

  Referring to FIG. 6, in the vertical length of the connecting portion, when the bra is arranged such that the distance between the front center side of the cup portion of the shoulder strap portion becomes maximum, the cup lowermost points B1 and B2 are set. Corresponds to the connecting portion on the line segment L3 with respect to the length of the line segment L3 connecting the middle point K of the connecting line segment and the middle point R of the line segment connecting the center front side end point Q1 and Q2 of the shoulder strap The ratio L4 / L3 of the lengths of the line segments L4 is preferably 0.10 to 0.50, and more preferably 0.15 to 0.45. In addition, the line segment L4 corresponding to the connection part site | part on line segment L3 means the set of the intersection of the perpendicular drawn on the line segment L3 from the connection part, and the line segment L3. When the ratio is 0.10 or more, the installation area of the cup portion and the connection portion is sufficiently secured, so that the cup and the chest are in close contact with each other in the center of the cup, and the side portion starts from the wing portion It becomes possible to fix a chest firmly from the front to the side of a cup by becoming a fixed point to extension power in the direction, and it is possible to control a minute vibration. Moreover, by being 0.50 or less, the area of the connecting part does not become excessively large, and it is possible to sufficiently maintain the opening area of the chest, and while the esthetics is high, the connecting part becomes hard. Wearing comfort does not decrease because it is just too much.

  The brassiere of the present disclosure exhibits good antivibration properties by having a specific antivibration portion. Therefore, since the application pressure of each part can be 50 hPa or less while suppressing the shaking of the chest, the maximum application pressure of the present disclosure can be 50 hPa or less, and an unpleasant feeling of tightening when worn can be avoided. Generally, in order to suppress chest sway, tightness is often tightened, and in particular bras with very high shoulder pressure are often found. However, when the pressure applied to each part of the bra exceeds 50 hPa, it generally tends to be uncomfortable. In the present invention, the chest movement in each of the X, Y, and Z directions is suppressed and dispersed, so that concentration of applied pressure can also be prevented. In particular, the above-mentioned reinforcement of the shoulder strap portion is excellent in the pressure distribution effect. The maximum application pressure is more preferably 45 hPa or less, still more preferably 40 hPa or less. On the other hand, the maximum application 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 viewpoints of suppressing displacement during wearing and suppressing shaking.

  The material of each member of the bra of the present disclosure (that is, the members that respectively configure the body cloth and the reinforcing portion) is not particularly limited, and synthetic fibers such as polyester fibers and polyamide fibers, and cellulose materials 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. Alternatively, crimped fibers may be used. In the present invention, it is effective to dispose a fabric having proper stretch characteristics to each member. In each member, a knitted fabric having an extension in which polyurethane elastic fibers are interwoven is suitably used. Moreover, double round knitting, tricot knitting, russell knitting, etc. can be used for the cloth of a cup and a wing part, and tricot half cloth is used suitably. As a knitting gauge of a knitting machine to be used, 20 to 40 GG is preferable. Also, for the high stress portion, a woven fabric or a warp-knitted material of warp insertion or the like is suitably used, and a lace or the like with a slight elongation is very suitably used because of its excellent design.

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

  The total fineness of the fabric material that constitutes each member of the bra of the present disclosure can be in a range generally used in clothing and the like. Among them, the total fineness is preferably about 22 to 700 dtex from the viewpoint of strength and softness.

Although the fabric weight of the fabric used for each member of a bra is not specifically limited, About 50-500 g / m < ² > is preferable.

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

  When a urethane pad is used for the cup, a urethane pad with a thickness of 2 to 15 mm is suitably used, but it is also preferable to use a three-dimensional knit in the cup to enhance air permeability.

  The fabric used for the reinforcing portion is not particularly limited, but it is composed of a fabric including polyurethane elastic fibers such as cotton fabric, polyester woven or knitted fabric, woven or knitted fabric of polyamide material or knitted fabric of power net structure, knitted fabric of two way structure, etc. can do.

  The bra of the present disclosure is extremely excellent in anti-vibration properties. The following method can be used to objectively evaluate the degree of shaking. Wear a bra on five subjects with a height of 160 cm ± 8 cm and a (Top bust size-Under bust size) value of 17.5 cm or more, and with a treadmill, speed of 5.5 km / h, pace of 150 steps per minute Then, when landing, make a small run so that one foot is away from the ground. At this time, a reflecting sphere with a diameter of 2.0 cm is attached to the clavicle and the bust top, and the reflecting sphere is photographed for 20 seconds by two high-speed cameras. As an index of chest sway when making a small run so that the scapula portion shakes to be about 7.0 cm, (Bast top sway)-(Clavicle sway) (cm) for 20 seconds (average of maximum values) -(Average of local minimum value) (cm) is calculated in three directions of horizontal (X), vertical (Y) and depth (Z). Here, the X direction means the lateral direction of the brassiere, and the Y direction and the Z direction are respectively perpendicular to the X direction. The largest value among the values in the three directions is taken as the shake when worn (cm), and divided by the value (cm) of (top bust size-under bust size) to obtain a shake value. If the swing value is 0.4 or less, the swing is small, which is advantageous. The fluctuation value is preferably 0.3 or less, more preferably 0.2 or less. The shake value is preferably as small as possible, but is preferably, for example, 0.03 or more, from the viewpoint of avoiding excessive pressure and easily obtaining a good wearing feeling.

The following method can be used to objectively evaluate the degree of fine shaking of the chest within the cup in the present disclosure. At the time of evaluation of chest shaking of the appearance mentioned above, a 3-axis accelerometer (SA12 ZSCA: made by Fuji Ceramics Co., Ltd.) is attached directly to the subject's bust top (which will be located inside the bra). At a speed of 5.5km / h on a red mill, at a pace of 150 steps per minute, make a small run so that one foot is separated from the ground when landing. In this case, in the measurement for 20 seconds, acceleration in x direction (horizontal direction), y direction (vertical direction), z direction (deep direction) is measured, and (average of maximum values) − (average value of minimum values) ) (M / s ² ) is calculated for each of the three directions. The lower the acceleration is, the smaller the slight shaking of the chest in the cup, and the smaller the value, the better. It becomes possible to suppress the fine vibration of the chest in a cup as it is 50 m / s < ² > or less especially, and it becomes possible to reduce the discomfort at the time of wear operation | movement.

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

The shoulder strap portion is composed of a yarn (draft 3.5) in which a 70 dtex nylon processed yarn is double covered with a warp of 640 dtex polyurethane (a draft 3.5) and a nylon processed yarn of 155 dtex alternately arranged, and a 155 dtex nylon processed yarn is used as a weft Fabrics were made. In W1, the width is 1.0 cm, the thickness is 1.5 mm, and in W2, the width is 1.0 cm, the thickness is 1.5 mm, and in the middle point W3, the width is 1.0 cm, the thickness is 1.5 cm (average cross-sectional area Mounted 15 mm ² ). The longitudinal extension of the shoulder strap was 68% at the center of the shoulder.

Comparative Example 3
In the bra of Example 1, the connection part was made of a tricot cloth of nylon 56 dtex, and was made. In the 10% cyclic extension test in the horizontal direction of the present joint, the extension stress at the third 10% extension was 5.2 N. Moreover, L4 / L3 which is an area of a connection part was 0.30. Other than that, the bra similar to Example 1 was produced.

Comparative Example 4
In the bra of Example 7, the connecting part was made of a tricot cloth of nylon 56 dtex and was made. In the 10% cyclic extension test in the horizontal direction of the present joint, the extension stress at the third 10% extension was 5.2 N. Moreover, L4 / L3 which is an area of a connection part was 0.30. Other than that, the bra similar to Example 7 was produced.

  As can be seen from the results of the example and the comparative example, by having a predetermined stress at the cup joint, the joint becomes a fixed point, and it becomes possible to bring the chest and the cup into close contact from the front to the side of the cup. It is possible to reduce the acceleration in each direction applied to the chest. For this reason, by being able to reduce the feeling of shaking at the time of operation, it is possible to obtain a bra having excellent comfort.

  In each example and comparative example, in addition to the predetermined connection portion, the presence of the vibration isolation portion makes it possible to reduce the overall large shaking while reducing the fine shaking, and corresponds to the discomfort when worn It is possible to obtain a bra having high comfort that can reduce the feeling of swinging.
