TECHNICAL FIELD OF THE INVENTION
The present invention relates to a shoulder strap of a bra sewn to a bra body composed of a cup member and side members, and more particularly to muscles of the back (ex. Dorsalis, great circle, deltoid muscle, etc.) and muscles from the armpits to the chest. By moving the side saw muscles and pectoralis major upwards as a whole, a correction effect that corrects the posture that tends to lean forward, a correction effect that lifts the shoulder that has fallen, and a bust It relates to the shoulder straps of the bra that can beautifully arrange the lines.
[0002]
[Prior art]
BACKGROUND ART Underwear for women, for example, underwear such as brassieres and body suits, has been conventionally devised in order to adjust the shape of a woman's bust and make the silhouette look beautiful.
[0003]
For example, in addition to providing a bulged cup part to directly shape the bust part, wire around the cup part, force acting to lift the breast and approaching the center part In order to apply a force acting on the cup portion, there is a device in which a device such as sewing a stretchable cloth piece around the periphery of the cup portion is used.
[0004]
In some cases, instead of directly acting on the cup portion, the flesh of the armpits is moved forward, so that the flesh that protrudes under the armpits is pressed into the undergarment together with the bust.
[0005]
All of these conventional women's underwear are focused on how beautiful the silhouette of the appearance looks, but they also take into account the structure of the human body (that is, how to attach and move muscles). is not.
[0006]
[Problems to be solved by the invention]
For this reason, for example, in a configuration in which the meat in the side part is moved forward and the meat part protruding under the armpit is pressed into the underwear, as shown in FIG. A stretchable cloth piece is used. Then, when attached to the body 91, the contraction force of the holder portion 81 (the force acting in the lateral direction: indicated by an arrow a) brings the meat 82 of the side portion forward, and the fastening force of the holder portion 81 moves the meat 82 under the armpit. The protruding meat portion is pressed into the holder portion 81.
[0007]
In other words, pressing the meat portion protruding under the armpit into the holder portion 81 means that the meat portion protruding under the armpit is pulled down.
[0008]
By the way, when the arm is raised, the muscles under the armpits (that is, the side saw muscles and the dorsi muscles) move in the directions indicated by arrows in FIGS. 8 and 9. That is, it moves from the side toward the shoulder. That is, in the women's underwear shown in FIG. 5, the movement of such muscles is regulated by the holder 81, which is not preferable for the body.
[0009]
Also, due to aging or fatigue of the body, shoulder muscles and back muscles (trapezius, sciaticus, greatis major muscle, deltoid muscle, etc.), and muscles from the armpits to the chest (side saw muscles and pectoralis major muscles) ) Weakness, the shoulders may look down, the lines of the left and right shoulders may not be aligned, or they may be leaning forward, but with conventional women's underwear, such shoulder sloping and unbalanced At present, there is no provision for correcting a posture such as leaning forward. Correcting the posture is also a prerequisite for making the bust line and the side lines beautiful.
[0010]
By the way, Japanese Patent Application Laid-Open No. 9-3708 proposes women's clothing in which a shoulder strap is formed into a circular or elliptical loop shape by using an elastic tape. In this women's garment, the loop-shaped shoulder strap exerts a force that directly pulls the side arm muscles, which are the armpit muscles, directly upward, but does not directly act on the back side of the wide spine muscles or the great circle muscles Therefore, a so-called posture correcting effect cannot be obtained. In addition, when viewed from the viewpoint of sewing, this women's clothing needs to be sewn from the outer upper edge of the cup portion to the upper edge of the holder portion with a loop-shaped elastic tape. There is also a problem that it is difficult to do.
[0011]
In addition, conventionally, there is what is called a so-called orthodontic bra.For example, this is forcibly holding both shoulders by arranging a shoulder strap so as to intersect with the back and giving the shoulder strap a strong contractility. It draws backwards and does not take into account the structure of the human body, especially how to attach and move muscles.
[0012]
The present invention has been devised to solve such a problem, and its object is to consider the manner of attachment and movement of the muscles of the back and armpits in particular, and to consider the manner of movement of the muscles of the back (trapezius, striated muscle). Muscles from the armpits, deltoid muscles, etc. and armpits to the chest (side saw muscles and pectoralis major) so as to push up (or up) as a whole (and simultaneously) along the movement of the muscles By acting, a bra that can fully demonstrate the correction effect that corrects the posture that tends to lean forward and the correction effect that lifts the shoulder that has fallen, that is, the correction effect that brings the muscle back to the normal position. To provide shoulder straps.
[0013]
[Means for Solving the Problems]
In order to solve the above problem, the shoulder strap of the brassiere according to claim 1 of the present invention is a shoulder strap sewn to a brassiere body composed of a cup member and a side member, wherein the shoulder strap is located behind an armpit. It is formed of one wide elastic cord-like member that goes from the lower part, passes under the armpits, turns around the shoulder, and reaches the stopper at the center of the back, and only one side edge of this wide elastic cord-like member Are sewn along the edge of the brassiere body.
[0014]
That is, the shoulder strap is formed of one wide elastic cord-like member, and the whole is formed into a so-called substantially ρ-shaped shape and sewn to the brassiere body. At this time, in order to allow the bra body attached to the body to naturally follow the movement of muscles and skin, the present invention provides a wide shoulder (for example, a width of about 20 mm) with excellent elasticity and fit. In order to use a string and maximize the original elasticity, as a part to be sewn along the edge of the brassiere body, a predetermined width from one side edge of the shoulder strap (for example, a width of about 5 mm) ) Is a seam allowance, and the remaining width from the seam allowance to the other side edge (that is, a width of about 15 mm) is not sewn, and is a free part capable of sufficiently exerting the expansion / contraction action.
[0015]
By the action of the shoulder straps when the brassiere is worn on the body, the muscles from the armpits to the chest (side saw muscles and pectoralis major) are strongly pulled up from the front to the shoulder, and the muscles on the back (mitral) Muscles, dorsi muscles, great circles, deltoid muscles, etc.) are also pulled obliquely upward toward the shoulders, so that the posture of lowering the shoulder and leaning forward is naturally corrected.
[0016]
Incidentally, the shape itself of such a shoulder strap, that is, the structure itself formed into a so-called substantially ρ-shaped shape and sewn to the brassiere body is also disclosed in FIG. 2 of Japanese Patent Publication No. 40-21098. In addition, the present applicant has disclosed it in JP-A-11-152608. However, in this bra, as shown in FIGS. 10A and 10B, the entire width of the shoulder strap 301 is overlapped with the edge of the brassiere body 302, and the overlapped whole is sewn. In the wearing part, the elasticity is reduced, and there is a problem that a corrective effect such as correcting the posture and a corrective effect such as lifting the dropped shoulder may not be sufficiently obtained, but with the structure of the present invention. By doing so, such a problem can be solved and a brassiere excellent in correction effect can be provided.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
FIG. 1 is a perspective view of a brassiere having a shoulder strap according to the present invention, FIG. 2 is an enlarged view of a sewn portion which is a characteristic part of the present invention, FIG. 3 is a perspective view of a state of being attached to a body, and FIG. .
[0019]
The brassiere comprises a cup member 1, a side member 2 for holding the cup member 1 on a body, a shoulder strap 3, and a stop which is attached to each end 2d, 2d of the side member 2 and which hooks each other. The tool parts (clasps and hook eyes) 4a, 4b.
[0020]
The present invention is particularly characterized by the shape of the shoulder strap 3 and the sewing structure.
[0021]
That is, the shoulder strap 3 is formed of a single cord-like member having a predetermined width (around 20 mm in the present embodiment) that can expand and contract in the longitudinal direction (the direction of arrow A in FIG. 1).
[0022]
Here, the shoulder strap 3 has a first predetermined length portion 3a from one end thereof along a first upper edge portion 2a extending from the outer upper edge portion 1a of the cup member 1 to the armpit lower portion of the arm member 2. A second sewing along the second upper edge 2b from the other end to the center of the back from the armpit to the second predetermined length 3b from the other end. It is sewn to the line L2. That is, the shoulder strap 3 is sewn so as to become the shoulder strap portion 3c via the first sewing line L1 and further to the catch 4a (or the hook eye 4b) via the second sewing line L2. Has a substantially ρ-shaped shape. At the common end 2c of the first sewing line L1 and the second sewing line L2, the shoulder straps 3 intersect, and the intersection is sewn.
[0023]
The first sewing line L1 is formed in a curved shape so as to extend along a line from the front side portion 23 to the rear side portion 24 of the body 21 through the lower side portion 22 when the first sewing line L1 is attached to the body 21 (FIG. 3). And FIG. 4). The second sewing line L2 is formed so as to be substantially along the muscles of the back (such as the dorsi dorsi muscle or the great circle muscle) when attached to the body 21 (see FIG. 4).
[0024]
FIG. 2 shows a sewing structure of the first sewing line L1, that is, a sewing structure of the first predetermined length portion 3a of the shoulder strap 3.
[0025]
As described above, the shoulder strap 3 is formed wide, and its width is about 20 mm. In this width, as a portion to be sewn to the first sewing line L <b> 1, a width portion around 5 mm from one side edge 31 of the shoulder strap 3 is defined as a seam allowance portion 32. In other words, the only part to be sewn to the outer upper edge 1a of the cup part 1 and the first upper edge 2a of the side member 2 is the seam allowance 32, and the remaining width from the seam allowance 32 to the other side edge. (That is, a width portion of about 15 mm) 33 is a free portion that does not sew and can sufficiently exhibit an expansion / contraction action.
[0026]
It should be noted that such a sewing structure is applicable not only to the first sewing line L1 but also to the second sewing line L2. Thereby, a sufficient stretching action can be exerted over the entire shoulder strap 3 without losing the stretchability of the entire shoulder strap 3.
[0027]
If the width of the shoulder strap 3 is set to, for example, 15 mm and the width of the sewing allowance is set to 5 mm, the free portion capable of sufficiently exerting the expansion and contraction action becomes about 10 mm in width, and sufficient elasticity may not be obtained. Also, when the width of the shoulder strap is, for example, 25 mm or 30 mm, and the width of the seam allowance is 5 mm, the free portion capable of sufficiently exerting the stretching action is about 20 to 25 mm wide, and sufficient stretching property is obtained. However, the width may be too large and the fit to the body may be slightly reduced. For these reasons, a width of about 20 mm is considered to be the optimum width that can satisfy both sufficient elasticity and fit to the body.
[0028]
Next, the action of correcting the shoulder strap of the brassiere according to the present invention will be specifically described with reference to the state at the time of mounting shown in FIGS.
[0029]
That is, when the brassiere is attached to the body 21, the shoulder strap 3 hung over the shoulder 25, as shown by the two-dot chain line in FIGS. 8 and 9, the muscles of the side saw muscle, the pectoralis major, the deltoid muscle, and the striated muscle. Since it has reached the center of the back through the position of the tip of the fold, as shown by arrows in FIGS. 3 and 4, the force of strongly pulling from the armpit lower part 22 to the front armpit part 23 works. The muscle in this part is moved (see FIG. 3), and at the end 2c, which is the intersection of the shoulder straps 3, the force of pulling in the direction of the shoulder 25 and the center of the back (the direction of the clasp 4a and the hook eye 4b) acts, The muscles on the back side (trapezius etc.) are moved (see FIG. 4). Therefore, the lowered shoulder returns to the normal position. In addition, as a result of the pulling force strongly pulling the underarm brisk meat forward, the effect of raising the bust by bringing it up is also obtained. As described above, only the seam allowance portion 32 is sewn to the outer upper edge portion 1a of the cup portion 1 and the first upper edge portion 2a of the side member 2, as described above, and the remaining width portion of about 15 mm is provided. Reference numeral 33 denotes an effect obtained by forming a free portion that does not sew and that can sufficiently exhibit expansion and contraction.
[0030]
In addition, the force of pulling up the side portions 22, 23, and 24 upwards gives a light feeling as if the force of the shoulder strap 3 applied to the shoulder 25 is released, and the wearing feeling is also good.
[0031]
Incidentally, in the conventional shoulder strap 84 shown in FIG. 6, only the force for pulling up the back portion of the holder portion 85 acts only, and in the one shown in FIG. 7, only the force for pulling up the hook portion 86 of the holder portion 85 upwards. Not working. In other words, there is no action of pulling up the side portions 22, 23, and 24 along with the movement of the muscles (side saw muscle, wide back muscle, etc.).
[0032]
In the above embodiment, the case where the present invention is applied to a shoulder strap of a bra is described. However, the present invention is not limited to this. For example, a shoulder such as a piche, a body suit, a swimsuit, a leotard, or the like may be used. It can also be applied as a string.
[0033]
【The invention's effect】
According to the shoulder strap of the brassiere according to the present invention, the muscles (side saw muscles and pectoralis major) from the armpits to the chest are strongly pulled up from the front to the shoulder by the stretching action of the entire shoulder strap when worn on the body. At the same time, the back muscles (trapezius, giant dorsi, great circles, deltoids, etc.) are also pulled diagonally upward toward the shoulders, so that the lowering of the shoulders is corrected and the posture of leaning forward naturally. It will be corrected. In addition, by correcting the lowering of the shoulder and the leaning posture, the total line from the shoulder line to the chest, the side, and the back can be beautifully arranged.
