DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited to these embodiments.

[0010] <Basic composition of upper body clothing 1> Fig. 1 is a front view of an upper-body garment 1 of this embodiment, Fig. 2 is a back view of the upper-body garment 1 of this embodiment, and Fig. 3 is a front view of the upper-body garment 1 of this embodiment in an inside-out state. First, the overall configuration of upper-body garment 1 of this embodiment will be described with reference to Figures 1, 2, and 3. In the following description, the upper side, lower side, left side, and right side of upper-body garment 1 of this embodiment will be defined by the directions of the arrows shown in Figures 1 and 2, i.e., the up, down, left, and right directions in Figures 1 and 2.

[0011] As shown in Figures 1 and 2, upper-body garment 1 of this embodiment is a so-called half-top type underwear. Upper-body garment 1 comprises a front body section 2 that covers the chest side of the wearer and a back body section 3 that covers the back side of the wearer. The front body section 2 and the back body section 3 are formed continuously in a tubular shape so as to cover the area around the wearer's chest. Upper-body garment 1 comprises a pair of left and right straps 6 (front body strap 6a and back body strap 6b) that are attached from the upper part of front body section 2 to the upper part of back body section 3.

[0012] The front body 2 comprises a pair of left and right bust sections 4 that cover the wearer's bust, a pair of left and right front body side straps 6a that are continuous with the upper parts of the bust sections 4, a second support section 201 provided at the lower part of the bust sections 4, and a base section 5 that is continuous with the lower part of the second support section 201.

[0013] The back body 3 includes a back center section 8 that covers the area along the wearer's spine, a pair of left and right back body side straps 6b that are continuous with the upper part of the back center section 8, and back side sections 9 and first support sections 101 that are provided in pairs on both the left and right sides of the back center section 8. Furthermore, the back body 3 includes auxiliary support sections 301 at the lower parts of the back center section 8 and the back side sections 9.

[0014] The upper-body garment 1 of this embodiment includes an under section 7 (front-side under section 7a, back-side under section 7b) formed continuously in a circular shape at the lower part of the front body section 2 and the back body section 3. Furthermore, the upper-body garment 1 is provided with edge tapes 111, 131 at the neckline 11 and the armpits 13 of the front body section 2 and the back body section 3, respectively.

[0015] <Front body 2> The front body 2 will be described in more detail below. The front body 2, excluding the front body straps 6a and the front body under-part 7a, is formed of a main body fabric 21a that is exposed to the outside when worn, and a lining fabric 21b that is provided on the back side of the main body fabric 21a, i.e., the side that faces the wearer's skin. The main body fabric 21a and lining fabric 21b form a double layer for the bust section 4, base section 5, and second support section 201. The main body fabric 21a is a single piece of fabric that continues from the front body straps 6a, and there are changes in the knit fabric at each boundary between the front body straps 6a, bust section 4, base section 5, and second support section 201. The lining fabric 21b is also a single piece of fabric, and there are changes in the knit fabric at each boundary between the bust section 4, base section 5, and second support section 201.

[0016] The main fabric 21a and the lining fabric 21b basically have substantially the same shape, but a portion of the upper end 211 of the lining fabric 21b protrudes above the bust area 4 so as to overlap the front body straps 6a (see FIG. 3). The main fabric 21a and the lining fabric 21b are arranged to overlap each other and are sewn together along the periphery of the front body 2. Here, the periphery of the front body 2 refers to the neckline 11, the side openings 13, and the second side edges 55 (see below) of the base 5 that form both ends of the front body 2, as well as the under-body area 7. As a result of the main fabric 21a and the lining fabric 21b being sewn together along the periphery of the front body 2 in this manner, a space is formed between the main fabric 21a and the lining fabric 21b that can accommodate cups that cover the bust.

[0017] The bust section 4 is formed into a three-dimensional shape to accommodate a cup therein. The bust section 4 has an upper end 41 on the main body fabric 21a side that is continuous with the front body straps 6a, a first side edge 43 along the neckline 11, a second side edge 45 along the armpits 13, and a lower edge 47 connecting the left and right second side edges 45. A central seam 49 is provided between the left and right bust sections 4, extending from the first side edge 43 to the lower edge 47. The main body fabric 21a and the lining fabric 21b of the bust section 4 are joined together at this central seam 49. This separates the interior space of the bust section 4 into left and right sections, separated by the central seam 49. In this embodiment, the central seam 49 is gathered to accentuate the rounded bust line.

[0018] As shown in Figure 3, the upper end 211 of the bust area 4 on the lining fabric 21b side is not sewn to the front body 2 and is free. This leaves an opening 45 between the main fabric 21a and the lining fabric 21b for inserting and removing the cup. The cups of this embodiment are preferably thin and resistant to deformation so that they can be accommodated in the bust area 4, and are preferably 3 / 4 cups that can easily conform to any breast shape. The material of the cups is not particularly limited, but can be selected from foams such as polyurethane, polystyrene, polypropylene, polybutadiene, natural rubber, synthetic rubber, and silicone.

[0019] Next, the second support portion 201 will be described. As described above, the second support portion 201 is provided below the bust portion 4. The second support portion 201 is formed in a strip shape extending along the lower edge 47 of the bust portion 4. More specifically, the second support portion 201 includes an upper edge 2011 that is continuous with the lower edge 47 of the bust portion 4, side edges 2013 that are aligned with the armholes 13, and a lower edge 2015 that extends below the upper edge 2011. The second support portion 201 curves along the curve of the lower edge 47 of the bust portion 4. Specifically, the second support portion 201 curves so as to protrude from the left and right armholes 13 toward the under-bust portion 7. The second support portion 201 is formed to have a predetermined width, and the width W1 increases from the center of the second support portion 201 toward the left and right side edges 2013.

[0020] The second support portion 201 is formed so as to fit along the lower edge of the cup housed in the bust portion 4. That is, the lower edge 2015 of the second support portion 201 is substantially aligned with the position of the lower edge of the housed cup. Furthermore, the second support portion 201 is formed in a position that follows the outline of the lower part of the bust, i.e., the verge line. This allows the second support portion 201 to support the bust from below.

[0021] Next, the base portion 5 will be described. The base portion 5 is formed in the area between the second support portion 201 and the under portion 7. Specifically, the base portion 5 mainly covers the area from under the bust to the side of the bust, and further from the side of the bust to the armpits. The base portion 5 includes an upper edge portion 51 that is continuous with the lower edge portion 2015 of the second support portion 201, a first side edge portion 53 formed along the armpit opening 13, a second side edge portion 55 that is continuous with the first support portion 101 of the back body portion 3, and a lower edge portion 57 that is continuous with the upper edge portion 71 of the under portion 7. In this embodiment, the base portion 5 is formed so that the width W2 between the upper edge portion 51 and the lower edge portion 57 is widest on the side of the armpit opening 13 and narrows toward the center of the front body portion 2.

[0022] The front body straps 6a are formed continuously from the upper end 41 of the bust portion 4 of the front body 2. The upper end 61a of the front body straps 6a is sewn to the upper end 61b of the back body straps 6b at a seam 611.

[0023] <Back 3> The back body section 3 will be described in more detail below. Unlike the front body section 2, the back body section 3 is formed in a single layer from a single piece of fabric. That is, the back center section 8, back body side straps 6b, back side sections 9, first support sections 101, and auxiliary support sections 301 are formed from the same fabric, and the knitting fabric is switched at these boundaries except for the boundary between the back center section 8 and the back body side straps 6b.

[0024] First, we will explain the back center region 8. The back center region 8 of the back body 3 is formed in a roughly Y shape, branching out from the region along the wearer's spine toward the left and right shoulder blades. The back center region 8 includes an upper end 81 formed of a knit fabric continuous with the back body straps 6b, an upper edge 83 along the neckline 11, left and right side edges 85 continuing with the back armpits 9, and a lower edge 87 continuing with the support auxiliary parts 301.

[0025] The back central portion 8 covers the area along the spine below the neckline 11 and branches out to the left and right along the neckline 11. The upper end 81 of the portion formed along the neckline 11 reaches the armpits 13 and is continuous with the left and right back straps 6b. Because the back central portion 8 and the left and right back straps 6b are continuously formed from the same fabric and the same knit, there are no seams, transitions, or other visible lines between them (at the upper end 81). For ease of explanation, the height at which the side edges 85 of the back central portion 8 reach the armpits 13 is defined as the upper end 81 of the back central portion 8, and this upper end 81 is defined as the imaginary boundary between the back central portion 8 and the back straps 6b.

[0026] The upper edge 83 of the back central portion 8 is recessed in an arc downward along the neckline 11. The left and right side edges 85 are recessed in an arc toward the neckline 11 and the center of the back. The width W3 of the lower edge 87 of the back central portion 8 is wider than the width W5 of the back side portions 9 and the width W6 of the first support portion 101. The width W4 of the back central portion 8 along the neckline 11 is approximately the same as or slightly wider than the width W7 of the back body side straps 6b.

[0027] Next, the back side portions 9 will be described. The back side portions 9 are formed in a vertically elongated quadrilateral shape. The back side portions 9 include upper edges 91 along the armholes 13, side edges 93 continuing with the side edges 85 of the back central portion 8, side edges 95 continuing with the side edges 1013 of the first support portion 101, and a lower edge 97 continuing with the upper edge 3011 of the auxiliary support portion 301.

[0028] The side edges 93 of the back side portions 9 project in an arc shape toward the neckline 11 and the center of the back. In terms of the relative positions of the lower edge 97 and the upper edge 91, the lower edge 97 is located closer to the center of the back than the upper edge 91. As a result, the pair of left and right back side portions 9 are formed to expand laterally from the lower edge 97 to the upper edge 91.

[0029] The width W5 at the lower edge 97 of the back side portion 9 is narrower than the width W3 at the lower edge 87 of the back central portion 8. In this embodiment, the ratio of W5:W3 is 7:10. The widthwise length ratio between the two is not limited to this, and may be in the range of W5:W3 = 5:10 to 9:10. Furthermore, in this embodiment, the back side portion 9 is formed to occupy an area of ​​approximately half of the entire back body portion 3.

[0030] Next, the first support part 101 will be described. The first support part 101 is formed in a vertically long, approximately rectangular shape. The first support part 101 has an upper edge part 1011 along the armholes 13, a side edge part 1013 continuing with the side edge part 95 of the back side part 9, a side edge part 1015 continuing with the base part 5, and a lower edge part 1017 continuing with the under part 7.

[0031] The first support portion 101 is formed so that the width W6 at the lower edge 1017 is shorter than the width W5 at the lower edge 97 of the back side portion 9. In this embodiment, the ratio of W6:W5 is 2:5. However, the ratio of the widthwise lengths of the two is not limited to this, and may be in the range of W6:W5 = 1.5:5 to 3:5.

[0032] Next, the support auxiliary part 301 will be described. The support auxiliary part 301 is formed in a strip shape of a predetermined width extending along the under part 7. The support auxiliary part 301 includes an upper edge part 3011 continuing with the lower edge part 87 of the back center part 8 and the lower edge part 97 of the back side part 9, a side edge part 3013 continuing with the side edge part 1013 of the first support part 101, and a lower edge part 3015 continuing with the under part 7. The width W8 between the upper edge part 3011 and the lower edge part 3015 of the support auxiliary part 301 is not particularly limited, but is preferably formed in the range of 3 to 150 mm.

[0033] The back straps 6b are formed continuously from the upper end 81 of the back center portion 8, and are positioned so that they rest on the shoulder blades when worn. The upper end 61b of the back straps 6b is sewn to the upper end 61a of the front straps 6a at a seam 611.

[0034] <About the knitted fabric> The upper-body garment 1 of this embodiment is formed from multiple different types of knitted fabrics. Here, "knitted fabric" refers to the knitting method (knitting structure) that forms the fabric. In other words, different types of knitted fabrics exist within the same piece of fabric. Note that it is possible to select an appropriate method, such as sewing together multiple knitted fabrics with different elasticity for each part to create a product, or using a knitted fabric that combines multiple parts with different elasticity by changing the knitted fabric. However, changing the knitted fabric within a single piece of fabric, as in the upper-body garment 1 of this embodiment, is more preferable because it does not create seams and does not impair the wearing comfort.

[0035] The upper-body garment 1 of this embodiment comprises three types of knitted fabrics (first knitted fabric, second knitted fabric, and third knitted fabric) each with different stretchability. Here, "stretchability" refers to the property of how much a fabric can be stretched relative to its original length. Of these knitted fabrics, the first knitted fabric constitutes the base section 5, back center section 8, straps 6, first support section 101, and auxiliary support section 303. The second knitted fabric constitutes the bust section 4 and back side sections 9. Furthermore, the third knitted fabric constitutes the second support section 201.

[0036] Among the knitted fabrics, the first knitted fabric has the lowest stretchability compared to the second knitted fabric and the third knitted fabric. On the other hand, the second knitted fabric has the highest stretchability compared to the first knitted fabric and the third knitted fabric. Furthermore, the third knitted fabric has a relatively high stretchability compared to the first knitted fabric, but a relatively low stretchability compared to the second knitted fabric. In other words, the relative relationship of the stretchability of each knitted fabric is first knitted fabric < third knitted fabric < second knitted fabric. The third knitted fabric has high stretchability in the horizontal direction. Here, "stretchability" refers to the property of how much a fabric can be stretched relative to its original length and how much restoring force it has to return to its original length.

[0037] A knitted fabric with low stretchability is less stretchable than a knitted fabric with high stretchability, and therefore tends to exert a constricting force on the body when worn due to the fabric being pulled with a certain force. On the other hand, a knitted fabric with high stretchability is more stretchable than a knitted fabric with low stretchability, and therefore tends to exert a constricting force on the body less.

[0038] The knitted fabrics of this embodiment are weft knitted; specifically, the first knitted fabric is pique knitted, the second knitted fabric is jersey knitted, and the third knitted fabric is rib knitted. The types of knitting structures of the first, second, and third knitted fabrics are not limited to these, and may be warp knitted fabrics such as tricot knitted, raschel knitted, double raschel knitted, or mesh fabric. Furthermore, cellulosic materials such as cotton and rayon, and synthetic materials such as nylon, polyester, and polyurethane can be used alone or in combination as appropriate, and the addition of rayon in particular gives the fabric good stretch and a soft feel.

[0039] <Layout of each knitted fabric and its function> The arrangement of each knitted fabric and its function will be described in detail below with reference to Figures 4, 5, and 6. Figure 4 is an enlarged side view of upper-body garment 1 of this embodiment, and Figure 5 is a perspective view of upper-body garment 1 of this embodiment worn as seen from the back. In Figure 5, the area surrounded by a dashed line indicates the position of the shoulder blades.

[0040] The first knitted fabric (piqué knit) is a fabric that is less stretchy than other knitted fabrics, and is therefore placed in areas where tightness of the fabric is required when wearing the upper body garment 1, namely the base portion 5, the first support portion 101, the central back portion 8, the front body straps 6a, the back body straps 6b, and the support auxiliary portion 301.

[0041] As described above, the base portion 5 is formed with a double layer of main fabric 21a and lining fabric 21b. Specifically, lining fabric 21b of the base portion 5 is placed on the back side of main fabric 21a and sewn to the back side of main fabric 21a along the side edge portion 23b of lining fabric 21b (sewn portion 551). The base portion 5, which is formed with a double layer of fabric from the first knitted fabric, effectively has twice the tightening force compared to the first support portion 101, back center portion 8, and straps 6, which are made of a single layer of fabric from the first knitted fabric. In this way, the stronger tightening force of the base portion 5 tightens the area from the sides of the wearer's bust to underarms, preventing side fat from slipping to the sides and shaping the bust line.

[0042] The first support portion 101 is knitted from the same first knitted fabric as the base portion 5, and is formed continuously from the base portion 5 via the sewn portion 551. Because the first support portion 101 is formed in a single layer from the first knitted fabric, the tightening force is essentially half that of the base portion 5, which is formed in a double layer. By making the tightening force weaker than that of the base portion 5 in this way, the difference in tightening force between the base portion 5 and the back side portion 9 can be alleviated.

[0043] That is, as will be described later, the back side portions 9 formed from the second knitted fabric are the most stretchable portions of the fabric that make up the front body 2 and the back body 3. On the other hand, the base portion 5 formed from a double layer of the first knitted fabric is the least stretchable portion of the fabric that makes up the front body 2 and the back body 3. When stretchy and non-stretchy fabrics are placed adjacent to each other in this way, unevenness or wrinkles may occur at the transition portion that forms the boundary between the knitted fabrics. This is because the stretchy knitted fabric is pulled by the non-stretchy knitted fabric.

[0044] In this regard, in the case of the upper-body garment 1 of this embodiment, by disposing the first support portion 101 between the base portion 5 and the back side portion 9, the difference in extensibility between the base portion 5 and the back side portion 9 is alleviated, and unevenness and wrinkles in the knitted fabric can be prevented. As a result, a moderate amount of tightening is achieved from the sides of the bust to under the armpits without compromising comfort.

[0045] The back center portion 8 is formed in a single layer from the first knitted fabric, similar to the first support portion 101. Furthermore, the straps 6 are also formed from the first knitted fabric, continuing from the back center portion 8. In this way, the back center portion 8 and the straps 6 continuing therefrom are formed from the first knitted fabric, which is less stretchy than the second knitted fabric, thereby supporting posture along the spine and making the back appear slimmer. Furthermore, the straps 6 lift and support the bust portion 4, maintaining the bust line.

[0046] The support auxiliary part 301 is formed in a single layer from the first knitted fabric, like the first support part 101 and the back central part 8, but is formed to be slightly less stretchable than the first support part 101 and the back central part 8. This makes the tightening force of the support auxiliary part 301 stronger than that of the first support part 101 and the back central part 8, and can alleviate the difference in tightening force between the back central part 8 or the back side part 9 and the back body side under part 7b.

[0047] The second knitted fabric (plain knit) is the most stretchy compared to the other knitted fabrics, and is therefore arranged in the bust region 4 and back side regions 9, which require fabric stretch when the upper-body garment 1 is worn. Of these, the bust region 4 is double-layered with a main fabric 21a and a lining fabric 21b. Therefore, the bust region 4 has less stretch than the back side regions 9, which are also made of the second knitted fabric. This allows the bust region 4 to have sufficient clamping force to support the bust. Meanwhile, the bust region 4 is formed into a three-dimensional knit using the second knitted fabric, which is more stretchy than the first knitted fabric, and is therefore suitable for accommodating three-dimensional cups, allowing for a rounded bust line to be created without crushing the bust.

[0048] The back side portions 9 are formed in a single layer from the stretchy second knitted fabric, and therefore exert the weakest tightening force when worn. As such, the back side portions 9, which are continuous with the side edges 85 of the back central portion 8 and located below the back body straps 6b, are formed to be stretchy, so muscle movement is not inhibited and a comfortable fit is not compromised. On the other hand, because the back side portions 9 are continuous with the back central portion 8 and the first support portion 101, they can indirectly assist the straps 6 in supporting the bust and the base portion 5 in tightening the side flesh.

[0049] Furthermore, because the side edge 93 of the back side portion 9 curves in an arc and enters the back central portion 8, a larger area of ​​the back side portion 9 in the back body 3 can be secured, improving the stretchability of the fabric below the shoulder blades. Also, because the side edge 93 of the back side portion 9 curves in an arc, the back side portion 9 stretches over a wider range when the fabric is pulled from the back central portion 8 (see the arrow in Figure 5). This results in less restriction of the wearer's movement and an improved fit.

[0050] The third knitted fabric (rib knit) has a stretchability intermediate between the first and second knitted fabrics, and is highly stretchable in the lateral direction. The third knitted fabric, which has such properties, is arranged in the second support section 201. By arranging the second support section 201, which is less stretchable than the bust section 4 but more stretchable than the base section 5, between the bust section 4 and the base section 5 in this way, it is possible to alleviate the difference in tightening force between the bust section 4 and the base section 5, and to neatly shape the rounded three-dimensional shape of the cup. Furthermore, because the second support section 201 has high stretchability in the lateral direction, it is possible to properly support the cup from below and achieve a good fit in the bust section 4.

[0051] FIG. 6 is a diagram showing a schematic representation of the relative relationship of stretch rates. In FIG. 6, (1) through (5) are assigned according to the degree of stretch rate. That is, the part with the lowest stretch rate, i.e., the part where the fabric is least stretchable, is assigned (1). Conversely, the part with the highest stretch rate, i.e., the part where the fabric is most stretchable, is assigned (5). As shown in FIG. 6, the relative relationship of stretch rates is (1) base portion 5<(2) second support portion 201<(3) bust portion 4<(4) back center portion 8, strap 6, first support portion 101<(5) back side portion 9. The back central portion 8, the straps 6, and the first support portions 101 do not need to have the same elongation rate as long as they are formed to have a lower elongation rate than the back side portions 9.

[0052] Looking at the relative relationship between the front body 2 and the back body 3, the front body 2 is made of fabrics (1) to (3) with relatively low elongation rates, while the back body 3 is made of fabrics (4) to (5) with relatively high elongation rates. In other words, the front body 2 side of the upper-body garment 1 as a whole has a lower elongation rate and a higher tightening force than the back body 3 side.

[0053] Looking at the front body 2, (1) base section 5 and (2) second support section 201 are provided to surround the central (3) bust section 4 from both the left and right sides and from below. In this way, the stretch rate increases in the order of (1), (2), and (3) from both the left and right sides of the front body 2 to the center, and further from the bottom to the top. As a result, the tightening force of the front body 2 increases stepwise from the bust section 4 to the left and right and below, providing appropriate support for the bust.

[0054] Looking at the back body 3, from both sides to the center of the back body 3, (4) first support section 101, (5) back side section 9, (4) back center section 8, and strap 6 are arranged in this order, with (4) having a relatively low stretch rate and (5) having a high stretch rate arranged alternately. This ensures comfort in the back body 2 due to the stretch of the fabric in (5) back side section 9.

[0055] As described above, the upper body garment 1 of this embodiment uses a combination of multiple different knit fabrics and some of the fabric is doubled, which makes it comfortable to wear even for long periods of time, while effectively preventing the bust from moving sideways and making the bust line look beautiful.

[0056] <Modification> Although the upper-body garment 1 of the first embodiment described above has the second support section 201 between the bust section 4 and the base section 5, such second support section 201 does not have to be provided. In other words, the upper edge section 51 of the base section 5 may be provided so as to be continuous with the lower edge section 47 of the bust section 4. In this way, by not providing the second support section 201, the manufacturing process can be simplified and manufacturing costs can be reduced.

[0057] Furthermore, although the upper-body garment 1 of the first embodiment has support auxiliary sections 301 between the back central section 8 and the back side sections 9 and the under section 7, such support auxiliary sections 301 do not have to be provided. That is, the upper edge 71 of the under section 7 may be provided so as to be continuous with the lower edge 87 of the back central section 8 and the lower edge 97 of the back side sections 9. In this way, by not providing support auxiliary sections 301, the manufacturing process can be simplified and manufacturing costs can be reduced.

[0058] Furthermore, in the upper-body garment 1 of the first embodiment, the bust section 4, second support section 201, and base section 5 are formed in a double layer using the main fabric 21a and the lining fabric 21b, but any of these sections, for example, the base section 5, may be formed in a single layer. In this case, the knitted fabric of the base section 5 may be any other knitted fabric instead of the first knitted fabric, and specifically, it is preferable that the knitted fabric have the same elongation rate and tightening force as when the first knitted fabric is doubled.

[0059] Furthermore, although the upper body garment 1 of the first embodiment is a so-called half-top type underwear, the length of the half-top may be lengthened to form a tank top or camisole type garment.

[0060] Although various embodiments and modifications have been described above, it is of course possible to combine these embodiments and modifications. Furthermore, the present disclosure is not limited to the above-described embodiments, and can be implemented in various forms without departing from the gist of the present disclosure.
