Abstract

PURPOSE:To prevent the distortion of the wearing state of a brassiere caused by the motion of human body by preparing a stretchable back cloth having a specific shape, sewing the back cloth to the outer side edges of the right and left cups and extending the cloth between both armpits via the back. CONSTITUTION:A stretchable back cloth 2 sewn to the outer side edge of a cup 1 has a shape gradually narrowing from the armpit side toward the center 3 of the back. Continuous stretchable hemming tapes 5a, 5b are placed along the upper edge and the lower edge of the back cloth and extended from one edge to the other edge. The tapes are narrowed and collected at the center 3 of the back. The wearing stability of the brassiere can be improved by the stretchable hemming tapes and the triangular truss structure part B.

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 due to various movements of the human body that occur when wearing a bra. Furthermore, the present invention relates to a bra that is always well-shaped and has a beautiful appearance without losing its shape.

BACKGROUND OF THE INVENTION Bras have traditionally been used as a foundation to prevent women's breasts from swinging, to support them, and to maintain a beautiful shape at all times. They can be replaced depending on the user's mood, and a wide variety of product types and structures have been proposed.

In general, a commonly worn brassiere has a stretchable bank cloth extending from the outer edges of both cup parts and having a width substantially parallel to each other, and using a rear part formed at the end of the bank cloth,
A bra that is removably tightened around the chest, or a continuous bank cloth is straddled between the outer edges of both cup parts, and the bra is removably tightened with a hook between the front centers of both cup parts. The main types of bras are so-called front-hook type bras, and so-called step-in type bras that do not use the above-mentioned locking means such as hook pieces that separate the left and right sides. In order to achieve the original function of shaping and retaining the shape of the bust area, the bank fabric extends to the outer edges of both cup areas and maintains its tightness.The upper and lower edges are approximately parallel to each other. It is manufactured in a wide range of widths.

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 that occur during the various movements that occur when wearing a bra, and therefore the breast shaping function,
From the viewpoint of shape-retaining function, bag cloths were inevitably produced in wide widths.

Indeed, such a bra with a stretchable bank cloth with a wide belt-like width has a modeling function that lifts drooping breasts and increases the bust size, and prevents the breasts from moving to the side. Although it provides a certain level of excellent tightening force to ensure stability, body surface ( skin) exhibits complex movements, and as a result, the upper and lower edges of the stretchable bank cloth are pulled together, causing the upper and lower edges to move irregularly with the movement of the human body. Horizontal wrinkles occur along the circumferential direction of the bra, and the bra does not have the same plastic appearance as when first worn, and the tightening force changes, which not only halves the shapeability and shape retention of the bra. This caused the clothes to fall apart, making them uncomfortable to wear, and the horizontal wrinkles appeared as ridge lines on the outerwear.Furthermore, during extreme exercise, the tightness of the bra, that is, the elastic back fabric, was tightened tightly, and the breasts were tightened tightly. In many cases, it is necessary to prevent the rocking of the
In addition to defects such as scratches on the contact surface of the brassiere due to frequent movement of the body surface, it is natural that the brassiere will wear out, such as slipping up or sliding down.

By changing the form of the back cloth placed from the outer edges of both cup parts to the back body, we improved the motor function of the human body.
It can fully respond to the expansion and contraction movements of the skin, and prevents the bra body from sliding up or down due to various movements, preventing it from falling off (and providing stability and exercise resistance functions). A brassiere suitable for this purpose has also been proposed, for example, in Japanese Utility Model Publication No. 58-15442.

In such a bra, the upper edge tape and the lower edge tape are narrowed and overlapped on both sides of the bra body, and then spread out radially to the back and are combined with straps to cover the left and right sides of the back body. Each has a triangular chevron-shaped outer shell, and a stretchable cloth is sewn inside the outer shell.

This brassiere maintains the features mentioned above, in that the upper and lower edge tapes are narrowed and overlapped in a dotted manner at the armpits, minimizing the contact area at the armpits where the amount of movement on the body surface is enormous. As a result, an elastic action similar to that of the body surface appears, preventing the bra from coming undone, and allowing the cup and back fabric to move independently without affecting each other. The shape-retaining function is influenced by the tightness of the back fabric, and since the front body and back body are separated at both sides, if they overlap in spots on both sides, the cup will inevitably become distorted. Since the tightening force of the parts is weakened and the force of pulling back and forth is applied to two points on both sides, lateral displacement may occur when worn.

There is a triangular truss structure on the left and right sides of the back body, and the idea is to use the core to minimize changes in the triangular shape and improve fit, but the truss structure is Since one side is formed by the shoulder straps, the shape of the truss structure does not change due to the expansion and contraction of the human body's shoulders, and the entire truss structure slides up, making it necessary to adjust the wearing position. Since the parts can be freely engaged and detached by a rear preparation, the expansion and contraction of the rear center part stops, and there is no force that attracts each other in the left and right direction, resulting in the defect that stability does 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 conventional defects mentioned above.
The elastic back fabric is sewn to the outer edges of the left and right cup portions of the bra body and is rolled slowly from both armpits to the back of the body, with a unique structure that flexibly responds to the movement functions of the human body surface. At the same time, it is an object of the present invention to provide a brassiere that can prevent the bra from falling apart due to the exercise.

Means for Solving the Problems In order to achieve the above-mentioned object, the brassiere according to the present invention has the following features:
It has an elastic bank cloth 2 forming a triangular truss structure B extending from the outer edge of the cup part 1 to the rear center part 3 and narrowing near the rear center part 3. Along with providing the elastic edging tape main body 4 along both edges,
Both tape bodies 4 are characterized by a brassiere that is in contact at least at the back center 3, and the two hemmed tape bodies 4 have one tape piece at the back center 3 so as to intersect in an X-shape. 5a and the other tape piece 5b are assembled, and the crossing part is sewn 6, and the double-edging tape main body 4 has one tape piece 5c and the other tape piece at the rear center part 3 so as to intersect in a U shape. The pieces 5d are gathered together, the intersection part is sewn 6, and the double-edging tape main body 4 is
One tape piece 5e and the other tape piece 5f are assembled at the rear center part 3 so as to be reversed and face each other, and both abutting edges are sewn 6, and a tape body 4 is attached to both edges.
is a flat string-like elastic tape piece 7, which is applied and sewn from the front or back side along both edges of the back cloth 2, and the double-edging tape body 4 is an elastic tape piece 8 formed by piping. This relates to a brassiere that is sewn along both edges of the bag cloth 2.

Next, specific examples 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 type of bra that can be straddled with a desired strap 9 or used as a strafe press. Appropriate latching pieces 1 that can be engaged and detached from each other
0, or a step-in type bra, in which the left and right cup portions 1 have an elastic back cloth 2 connected and integrated between the outer edges thereof. However, the shape of the elastic back cloth 2 is such that it extends from the outer edge of the cup portion 1 to the rear center portion 3, and at the same time gradually extends in the vicinity of the rear center portion 3. The truss structure part B is narrowed into a triangular shape.

Reference numeral 4 denotes an elastic edging tape main body, and the elastic edging tape main body 4 is placed along both the upper and lower edges of the elastic back cloth 2 forming the truss structure portion B described above. A structure is adopted in which at least the re-stretchable hemming 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 4 elastic edging tape bodies, for example, 1
When sewing the elastic tape piece 7 in the shape of a flat string with a width of about An example of using the edging tape body 4 is to sew elastic tape pieces 8 made of piping instead of the elastic tape pieces 7 along both edges of the bank cloth 2.

The effect when wearing the bra according to the present invention will be explained with reference to FIGS. 1 and 2. When the bra main body A is worn and it is fitted to the body surface, Along with each expansion and contraction force of the edging tape body 4,
A pulling force is applied in the directions a, b, c, d, e, f,
For this reason, the pulling force is concentrated at the base point g, which is the gathering point of the rear central portion 3.

As a result, forces a and d at the upper edge of the elastic edging tape main body 4 placed along the elastic back cloth 2 and forces C and f at the lower edge appear, causing the rear center The base point g, which is the gathering part of the rear central part 3, is subjected to a pulling force in the vertical direction of X and Y along the rear center line, and this causes a so-called tension phenomenon at the gathering part of the rear central part 3, and the rear center 3
The stability function of the area where the edging tape main bodies 4 are gathered is significantly improved.

In addition, when wearing a bra, the shape of the back cloth 2 is configured in 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. However, the change in the shape of the back body is very small,
In addition, even if a slight change in shape occurs, the restoring force is extremely excellent and can be exerted instantaneously, improving stability.

Effects of the Invention According to the present invention, as described above, the stretchable bank cloth 2 extending from the outer edge of the cup portion 1 of the brassiere body A is designed to be gradually thinner from the armpit side toward the rear center portion 3. , a continuous elastic edging tape 4° main body 4 extending from one side to the other is provided along the upper and lower edges of the bank cloth 2, and is in contact at the rear center part 3, so that The wearing stability function of the narrowed and gathered edging tape body 4 and the triangular truss structure B allows it to flexibly respond to the body surface, which is the movement function of the human body, and prevent the bra body from sliding up or down due to movement. The bra will not come loose at all, and a certain tightening effect as a brassiere will surely appear, and a synergistic effect with excellent exercise resistance function can be expected.

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

Further, in the case of the elastic tape piece 8 made by piping, the power is not as strong as that of the former, but the desired power can be obtained by, for example, sandwiching the tape piece.
