Description

  The present invention relates to a brassiere that can reduce fatigue during wearing.

Bras are worn for bust correction and protection, but products that emphasize the correction function have high tightening pressure during wearing, so the lower part of the bust, the side, the back, shoulders, etc. There was an adverse effect such as obstruction of blood flow and pain, which sometimes promoted fatigue.
Conventionally, a brassiere (for example, refer to Patent Document 1) in which the rear band portion is made of a highly stretchable fabric to eliminate the feeling of pressure on the side portions, and the shoulder strap and the rear band portion are made of a highly stretchable fabric. There is proposed a brassiere (see Patent Document 2, for example) configured to eliminate the feeling of pressure on the shoulder and side.

  In addition, the wire is placed inside the bust base line from the bottom of the bust to the side of the bust, and expands and contracts between this wire and the bust base line (from the bottom of the bust to the side of the approximately triangular side of the side). A brassiere with a cup wire that prevents the occurrence of pain due to the strong contact of the wire against the side of the bust while exerting a correction function that pushes the bust forward by arranging a sex cloth (for example, Patent Document 3) See also).

  However, in the above-mentioned conventional one, the cup part is sewn directly and integrally to the front base part, and the upper edge part of this cup part is connected to the rear band part with a shoulder strap. Since the shoulder is made to bear the weight of the bust, the degree of freedom in the vertical and horizontal directions of the cup part with respect to the front base part attached in close contact with the lower part of the wearer's bust by the rear band part is poor. It was a composition.

For this reason, there is a problem in that a strong compression force is applied to the shoulder portion of the wearer through the shoulder strap during the wearer's operation, for example, in the vertical direction, the horizontal direction, and the combined direction, and fatigue is easily promoted.
In addition, the compression force on the shoulder also spreads to the lower part of the bust, the side, and the back, and there are problems such as inhibiting blood flow in these parts and leaving a compression mark.

  Furthermore, the conventional shoulder strap uses only one elastic tape, such as span tape, and the elasticity imparted to the shoulder strap is integrated in the width direction of the strap so that it is actually loaded on the shoulder strap. It does not correspond to the difference in support force distribution.For example, when the load is large at one end in the width direction of the shoulder strap and small at the other end, the shoulder strap is strained on the side with a large load. The shoulder strap is loosened and lifted from the shoulder on the side where the load is small, and the shoulder strap as a whole will act on the side where the load from the bust is large. There were also problems such as increased fatigue and pressure marks.

Even when a wide stretchable tape is used, only one of the tapes is used, and thus the above problems are not solved. In addition, the use of a wide fabric has also been proposed, but even in this case, the elastic tape is only attached to the center of the shoulder strap in the width direction or to one side, However, it is not a solution to the above problem.
The present invention was developed in view of the above-mentioned problems of the conventional brassiere, and provides a brassiere that can be easily worn without getting tired by increasing the degree of freedom in the vertical and horizontal directions between the cup part and the front base part. It is intended to provide.

  To achieve the above object, the present invention includes a pair of left and right cup portions, a front base portion connecting the left and right cup portions, a pair of left and right rear band portions extending from both sides of the front base portion to the back side, A brassiere comprising shoulder straps connected at both ends in the middle of the rear band part from a part of the upper edge of the cup part, each having a substantially U between the lower side of the left and right cup parts and the front base part. The cup portion and the front base portion are connected with a mesh fabric having a letter-shaped belt-like stretch, and the rear band portion has a length that is less than one size difference of underbust as defined by JIS. A hook to adjust is provided. And the first wearer who wears one brassiere, the first wearer, the second wearer having the same undersize as the cup size prescribed by JIS and the underbust being one size larger, and the first wearer For the third wearer who has the same underbust and the cup size is one size larger, the first wearer wearing at the hook position where the rear band length is the shortest, and wearing at the hook position where the rear band length is the longest The difference in the wearing pressure at the lower part of the cup of the second wearer and the third wearer at the hook position which is the rear band length in the middle is the shoulder apex, the lower part around the cup, the buttocks and the back. It is characterized by being smaller than the difference in the wearing pressure in at least one of the above. In addition, when one wearer wears at the hook position where the rear band length is the shortest and when worn at the hook position where the rear band length is the longest, the difference in the wearing pressure at the lower part of the cup is the shoulder apex portion. It is characterized by being smaller than the difference in wearing pressure in at least one of the lower part around the cup, the buttocks and the back.

  According to this configuration, since the space between the cup part and the front base part can be expanded and contracted in the vertical direction and the left and right direction, the upper and lower parts of the bust with respect to the front base part are held while holding the bust shape retaining effect through the cup part by the shoulder strap. The degree of freedom in the direction can be increased, and the pulling force in the left and right direction by the rear band part can be relieved from being strongly applied to the bust through the cup part, and compression to the shoulder part, the cup lower part and the side part The feeling can be reduced. And by providing the said mesh fabric, the air permeability under a cup improves and it can aim at prevention of stuffiness.

The shoulder strap includes a wide stretchable fabric and two stretchable tapes provided on both sides in the width direction of the stretchable fabric so as to be independently stretchable along the longitudinal direction of the shoulder strap. It is characterized by comprising.
According to this configuration, since it is possible to impart independent stretchability separately in the width direction of the shoulder strap, the load from the bust is applied to the wearer's shoulder in a state corresponding to the distribution of the tensile force from the bust. It is possible to provide a brassiere that can be widely dispersed and supported, can reduce adverse effects such as blood flow inhibition and pressure marks, and can provide a comfortable wearing feeling without fatigue.

Further, the front fabric of the front base portion is made of a stretchable fabric, and a backside fabric made of a non-stretchable fabric is sewn on the back surface thereof, and the rear band portion has the same stretch as the front fabric of the front base portion. An elastic fabric is used, and an elastic tape is provided on the upper and lower edges of the elastic fabric along the longitudinal direction of the rear band portion.
According to this configuration, the front base portion is lined with the non-stretchable fabric and is made non-stretchable, so that the bust holding and correcting function can be ensured, and the front base is placed on the rear band portion. By using the same stretch fabric as the front cloth of the front part, the front base part and the rear band part have the same fabric structure, so there is no sense of incongruity in appearance, and along the upper and lower edges of the rear band part By providing an elastic tape, it is possible to assist the tightening force of the rear band part, and to prevent displacement and turning up during operation, and blood on the back and side of the wearer It is possible to provide a brassiere that can reduce adverse effects such as flow obstruction and pressure marks, and can provide a comfortable wearing feeling without fatigue.

Yes.

The cup portions 2 and 2 have a symmetrical heel shape, and a pad 2a and a lace fabric or other decorative surface fabric 2b are joined by sewing or the like. As the pad 2a, for example, a non-woven fabric is mainly used, in which a cotton sheet fabric is joined and integrated on the front surface (outer surface) and a tricot fabric is joined and integrated on the back surface (inner surface: skin side).
As shown in FIG. 2, the front base portion 3 is composed of a front side cloth 3a and a back side cloth 3b. The front side cloth 3a is, for example, a polyurethane elastic fiber yarn of 10 to 50 denier and a nylon yarn of 20 to 120 denier. The backside fabric 3b is made of a non-stretchable fabric such as marquisette, and a half tricot tape fabric 3c is sewn along the upper edge of the backside fabric 3b. An elastic tape fabric 3d such as a spun tape is sewn along the lower edge.

Then, between the lower side of the left and right cup parts 2, 2 and the front base part 3, the cup part 2 and the front base part 3 are interposed with mesh fabrics 6, 6 having substantially U-shaped belt-like stretchability, respectively. Are connected (see FIGS. 1 and 2).
As shown in FIGS. 1 and 3, the rear band portions 4 and 4 are made of the same stretch fabric as the front fabric 3a of the front base portion 3, and the rear band portions 4 and 4 are formed on the upper and lower edges of the stretch fabric. 4, elastic tapes 7 and 7 such as a span tape are sewn along the longitudinal direction.

As the shoulder straps 5 and 5, the same stretch fabric 5a as the front fabric 3a of the front base portion 3 is used, and the fabric 5a is folded wide as shown in FIGS. Along the longitudinal direction of the shoulder straps 5, 5, stretchable tapes 8, 8, such as span tape, are wrapped in the stretchable fabric 5 a, and the other is overlapped and sewn on the stretchable fabric 5 a. ing. As a result, the two stretchable tapes 8 and 8 are integrally sewn to a highly stretchable fabric 5a called a two-weight ricott fabric, and the stretchable tapes 8 and 8 are each in the width direction of the stretchable fabric 5a. It is sewn on both sides so as to be able to extend and contract independently within a certain range, and it cannot be obtained with the conventional single stretch tape while maintaining the same degree of elongation as the conventional shoulder strap. Shoulder straps 5 and 5 having unique stretch characteristics are formed. The elastic tapes 8 and 8 may have the same width (for example, 10 mm) or may have different widths, but are sewn to the elastic fabric 5a to such an extent that their inner end portions do not overlap. The applicable range of the shoulder straps 5 and 5 configured as described above may extend over the entire length, but may be at least a range from the upper ends of the cup portions 2 and 2 to the shoulder portion.

The configuration of the embodiment of the present invention is as described above. Next, its function will be described.
The brassiere 1 of the present invention includes a pair of left and right cup portions 2 and 2, a front base portion 3 that connects the left and right cup portions 2 and 2, and a pair of left and right rear sides that extend from both sides of the front base portion 3 to the back side. The left and right cup parts 2, 4 are provided with band parts 4, 4, and shoulder straps 5, 5 connected at both ends in the middle of the rear band parts 4, 4 from the upper edge part of the cup parts 2, 2. The cup parts 2, 2 and the front base part 3 are connected to each other between the lower side and the front base part 3 with mesh fabrics 6, 6 having substantially U-shaped belt-like stretchability.

  According to this structure, since the space between the cup parts 2 and 2 and the front base part 3 can be expanded and contracted in the vertical and horizontal directions, the shoulder straps 5 and 5 can provide a bust shape retaining effect through the cup parts 2 and 2. The degree of freedom in the vertical direction of the bust with respect to the front base part 3 can be increased while being held, and the lateral pulling force by the rear band parts 4, 4 is strongly applied to the bust through the cup parts 2, 2. Can be relaxed. Therefore, the brassiere 1 of the present invention can reduce the feeling of pressure on the shoulder portion, the cup lower portion and the side portions when worn. And the said mesh fabrics 6 and 6 can improve the air permeability under a cup, and can aim at prevention of a dampness.

Because it is possible to give independent stretchability separately in the string width direction, the load from the bust can be widely dispersed and supported on the shoulder of the wearer in a state corresponding to the distribution of the pulling force from the bust It is possible to provide a brassiere that can reduce the adverse effects such as blood flow inhibition and pressure marks, and can provide a comfortable wearing feeling without fatigue.

  Furthermore, the brassiere 1 of the present invention has a front side base part 3a in which the front side cloth 3a of the front side base part 3 is made of a stretchable cloth, and a back side cloth 3b made of a non-stretchable cloth is sewn on the back side. 3 becomes non-stretchable, and a bust holding and correcting function can be secured. Further, the brassiere 1 of the present invention uses the same stretchable fabric as the front cloth 3a of the front base part 3 for the rear band parts 4 and 4, so that the front base part 3 and the rear band parts 4 and 4 are used. And the same fabric composition, and the uncomfortable appearance is removed. Moreover, the brassiere 1 of the present invention has the above-described fabric configuration, and the elastic tapes 7 and 7 are provided along the upper and lower edges of the rear band portions 4 and 4, so that the rear band portions 4 and 4 The tightening force can be assisted while improving the elasticity, and it is possible to prevent misalignment and turning up during operation. Therefore, according to the brassiere 1 of the present invention, adverse effects such as obstruction of blood flow and pressure marks on the wearer's back and side portions are reduced, and a comfortable wearing feeling without fatigue is obtained.

5 to 7 are graphs showing wearing pressure data of examples of the present invention, which will be described next.
The embodiment product of the present invention is made as an M size brassiere, and the structure is such that the front fabric 3a of the front base part 3, the rear band parts 4, 4 and the shoulder straps 5, 5 are made of Asahi Kasei Co. It is made of fabric (85% nylon, 15% polyurethane), and the back fabric 3 of the front base 3
b is composed of a marquisette, and the stretchable tapes 7 and 7 of the rear band portions 4 and 4 and the stretchable tapes 8 and 8 of the shoulder straps 5 and 5 are composed of a stretchable tape (span tape) manufactured by Agoc. The pad 2a of the cup portions 2 and 2 is mainly composed of a nonwoven fabric, and is composed of a cotton sheeting fabric on the surface (outer surface) and a tricot fabric bonded and integrated on the back surface (inner surface: skin side). Consists of laces, hooks at the free ends of the rear band parts 4 and 4, and lengths in three stages (minimum, medium and maximum) at 1.4 cm intervals in the longitudinal direction of the rear band parts 4 and 4 Mounted for adjustment.

  FIG. 5 shows a case where a wearer of three sizes B70, B75, and C70 within an allowable range of an M size brassie made in the above configuration is worn (weared under conditions of B70 minimum, B75 maximum, and C70). It is the wearing pressure data of the result of measuring the wearing pressure of the shoulder apex, the lower cup periphery, the lower cup, the side, and the back. The vertical axis represents the wearing pressure in hPa, and the horizontal axis represents the measurement location. In addition, about the measurement of the wearing pressure, it measured using the pressure measuring apparatus by an air pack, specifically, the integrated pressure sensor "parasol type air pack" by an EI Techno Co., Ltd. product.

  6 and 7 show that the wearer size is B70 and B75 for each wearer, changing the position of the hook in three steps to change the underbust length to the minimum, medium, and maximum (each interval is 1.4 cm and the front and back are 2.8 cm). The wear pressure data is the result of measuring the wear pressure on the shoulder apex, the lower part of the cup, the lower part of the cup, the side, and the back when the pressure is changed in the range of hPa on the vertical axis and the horizontal axis. Represents a location. The measuring device is the same as described above.

From these wearing pressure data, the brassiere 1 of the present invention does not show a great difference in wearing pressure around the cup, side, back, etc. even if the size of the wearer and the underbust length are changed. It was verified that a brassiere that stretched well and reduced the feeling of tightening on the body was obtained.
Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications may be made. The brassiere of the present invention can be applied to both wireless and wire-equipped.
