Description

[Detailed Description of the Invention] Industrial Application Field The present invention minimizes changes in the shape of the back cloth without being affected by changes in expansion and contraction of the body surface caused by various movements of the human body that occur when wearing a brassiere. Furthermore, the present invention relates to a brassiere that is always well-shaped and has a beautiful appearance without losing its shape.

BACKGROUND TECHNOLOGY Brassiers have traditionally been used as foundations to prevent women's breasts from swinging, to support them, and to always maintain a beautiful breast shape. They can be replaced depending on the purpose and mood of the user, and a large number of product types and structures have been proposed. In the general form of a bra, a stretchable back cloth with a width approximately parallel to each other is extended from the outer edges of both cup parts, and a rear collar or the like formed at the end of the back cloth is used for engagement. A bra that can be removably tightened around the chest, or a continuous back cloth straddling the outer edges of both cup parts,
A so-called front-hook bra that is removably tightened with a hook between the front centers of both cup parts, or a so-called step-in bra that does not use any hook or other means to separate the left and right sides as described above. These are the main bras, but in order to achieve the original function of shaping and retaining the shape of the bust area, they are extended to the outer edges of both cup parts, and the tightness is The bag cloth to be maintained has a width in which the upper edge and the lower edge are substantially parallel.

In other words, if the elastic back cloth itself does not have a certain wide band width, it will not be able to support the oscillations of the breasts caused by the various movements that occur when wearing a bra, and therefore will not be able to support the breast shaping and shape retention functions. From this point of view, bag cloths were inevitably produced in wide widths.

Indeed, a bra with such a wide belt-like width and stretchable back cloth has a modeling function that lifts drooping breasts and increases the bust size, and prevents the breasts from moving to the side, making it stable to wear. However, during various movements of the human body, such as the expansion and contraction of the armpits, the up and down or rotational movements of the arms, and the expansion and contraction of the chest, the body surface (skin) ) exhibits complicated movements, and as a result, the upper and lower edges of the elastic bag fabric are pulled against each other, causing the upper and lower edges to move irregularly with the movement of the human body. Horizontal wrinkles occur along the circumference of the bra, and the brassiere does not look as neat as it was when first worn, and the tightening force shifts, which not only halves the shapeability and shape retention of the bra, but also causes it to fall apart. This resulted in poor wearing comfort, and there was also the problem that the horizontal wrinkles appeared as ridge lines on the outerwear.

Furthermore, the tightening force of the bra during extreme exercise,
That is, in many cases, the elastic back cloth is tightly tightened to prevent the breast from swinging as much as possible, and in such cases, the tightening causes pain, and the frequent movement of the body surface causes abrasions on the contact surface of the bra, etc. In addition to these defects, brazier slip-up or wear-off, such as sliding down, naturally occurred.

By changing the form of the back cloth placed from the outer edges of both cup parts to the back body, it can fully respond to the expansion and contraction of the skin, which is one of the motor functions of the human body, and prevent the shear of the bra body due to various movements. For example, bras that are suitable for so-called sports, which prevent them from rising or slipping down and preventing them from coming loose, and which have stability and exercise resistance functions, were developed in 1983.
Proposed in No. 15442.

In such a brassiere, the upper edge tape and the lower edge tape are narrowed and overlapped on both sides of the brassiere body, and then radially spread out to the back and are combined with the straps, thereby forming a tape at the rear. A triangular chevron-shaped outer shell is formed on each side of the body, and a stretchable cloth is sewn inside the outer shell.

This brassiere maintains the characteristics mentioned above, and since the upper and lower edge tapes are narrowed and overlapped in a dotted manner at the armpits, the contact area at the armpits, where the amount of movement on the body surface is enormous, is minimized. As a result, an elastic action similar to that of the body surface appears, preventing the bra from falling apart, and also allowing the cup and back cloth to move independently without affecting each other. The modeling function and shape retention function are influenced by the tightness of the back cloth.
In this way, since the front body and the back body are separated at both sides, if they overlap in a dotted manner at both sides, the tightening force at the cup will inevitably be weakened, and the force of pulling back and forth will be applied to both sides. Since it hangs over two points on the body, it sometimes causes lateral displacement when worn.

There is a triangular truss structure on the left and right sides of the back body, which is used to minimize the change in the triangular shape and provide a good fit. Since one side is composed of shoulder straps, the shape of the truss structure does not change when the human body's shoulders expand and contract, but the entire structure slides up, making it necessary to adjust the wearing position. Since the truss structure was made to be freely engageable and detachable by the rear rib, the expansion and contraction of the rear center part stopped, and no forces pulling each other in the left and right direction were generated, resulting in the defect that stability did not appear in the rear center part.

Problems to be Solved The brassiere of the present invention was developed with the aim of eliminating the above-mentioned conventional defects. A brassiere that flexibly responds to the movement function of the human body surface and prevents the bra from falling apart due to movement by configuring a stretchable back cloth that is rolled up from both sides to the back body in a unique form. The purpose is to provide

Means for Solving the Problems In order to achieve the above-mentioned object, the brassiere according to the present invention has a brassiere main body A suitably equipped with a cup portion 1, which extends from the outer edge of the cup portion 1 to the rear central portion 3. It has a stretchable back cloth 2 forming a triangular truss structure B that extends and narrows near the rear center portion 3, and stretches the stretchable hemming tape main body 4 along both edges of the back cloth 2. In addition, the two tape bodies 4 are characterized by a bra in contact at least at the rear central portion 3, and the two hemming tape bodies 4 are intersected at the rear central portion 3 in an X-shape. One tape piece 5a and the other tape piece 5b are gathered together, and the crossing part is sewn 6, and the double-edging tape main body 4 has one tape piece 5c at the rear center part 3 so as to intersect in a U shape.
and the other tape piece 5d are assembled, and the intersection part is sewn 6, and the double-edging tape main body 4 has one tape piece 5e and the other tape piece at the rear center part 3 so as to be reversed and face each other. Piece 5f is assembled,
The abutted ends are sewn together 6, and the tape main body 4 has a flat string-like elastic tape piece 7.
The present invention relates to a brassiere which is applied and sewn along both edges of the bag cloth 2 from the front side or the back side.

Next, specific embodiments of the brassiere according to the present invention will be described in detail.

A is a brassiere main body, and this main body A is a brassiere that can be installed across a desired strap 9 or used as a strap press. The bra is a front-hook type bra equipped with an appropriate hooking piece 10 that can be engaged and detached, or a step-in type bra that can be deployed. The back cloths 2 are connected and integrated to straddle each other, and the form of the stretchable back cloths 2 is such that each of them extends from the outer edge of the cup portion 1 to the rear center portion 3, and at the same time The truss structure part B is gradually narrowed in the vicinity of 3 and has a triangular shape.

Reference numeral 4 denotes a stretchable hemming tape body, which is laid along both the upper and lower edges of the stretchable back cloth 2 forming the truss structure portion B described above. A structure is adopted in which at least both elastic edging tape bodies 4 are in contact with each other at the rear center portion 3 while being sewn together.

More specifically, in each elastic edging tape body 4, one tape piece 5a and the other tape piece 5b are assembled so as to cross each other at the rear center part 3 to form an X shape. , when the crossing part is sewn 6, or each elastic edging tape main body 4 is connected to one tape piece 5c and the other tape so that they cross each other at the rear center part 3 to form a U-shape. The pieces 5d are gathered together, and the intersection is the suture 6.
or each elastic edging tape main body 4 has one tape piece 5e and the other tape piece 5f assembled so that the left and right sides are reversed and face each other at the rear center part 3. , and the case in which the two end edges abutting each other are sewn 6 is the case in which the structure is substantially developed.

In addition, when using the elastic edging tape body 4,
For example, a piece of elastic tape 7 in the form of a flat string about 1 cm wide may be used to sew along the upper and lower edges of the elastic bag cloth 2 from the front side or from the back side.

Now, to explain the effect when wearing the bra of the present invention with reference to FIGS. 1 and 2, when the bra main body A is worn and it is fitted to the body surface, the With each elastic force of the edging tape body 4, a, b, c, d,
A pulling force is applied in the directions e and f, and therefore the pulling force is concentrated at the base point g, which is the gathering part of the rear center portion 3.

Then, the pulling force a of the upper edge of the elastic edging tape main body 4 placed along the elastic back cloth 2
and d, and by the appearance of forces c and f pulled by the lower edge, the base point g, which is the gathering part of the rear central part 3, is
A pulling force is generated in the vertical direction of X and Y along the rear center line, which causes a so-called tension phenomenon at the gathering part of the rear center part 3, and the hemming tape of the rear center part 3 The stability function of the area where the main body 4 is assembled is significantly improved.

In addition, when wearing a bra, the shape of the back cloth 2 is configured into a triangular shape (the basic shape of a truss structure) that is the least likely to change when force is applied, so movement occurs on the body surface due to various complex movements of the human body. Also, the change in the shape of the rear body is extremely small, and even if a slight change in shape occurs, the restoring force is extremely excellent and can be exerted instantaneously, improving the stability function.

Effects of the Invention According to the present invention, as described above, the stretchable back cloth 2 extending from the outer edge of the cup portion 1 of the brassiere main body A is designed to be gradually thinner from the armpit side toward the rear center portion 3. , a continuous stretchable hemming tape main body 4 extending from one side to the other is provided along the upper and lower edges of the back cloth 2, and is in contact with the back center portion 3, so that it is narrowed at the back center portion 3. The wearing stability function of the hemming tape body 4 and the triangular truss structure part B, which come together at the same time, can flexibly respond to the body surface that is the movement function of the human body, and prevent the bra body from sliding up and down due to movement. There will be no wear and tear, and a certain tightening effect as a brassiere will definitely appear, and a synergistic effect with excellent motion resistance can be expected.

In addition, if the elastic tape piece 7 is applied from the front side of the bag cloth, the bag cloth will directly adhere to the body surface, eliminating any raised or uneven surfaces and creating a flat contact surface.
