Abstract
Description
Technical Field
[0001] The present invention relates to a night bra that can efficiently shape the bust and reduce the burden on the bust.
Background Art
[0002] Many bras worn during the day are tightly fastened so that they can firmly support the bust. Therefore, when a bra worn during the day is worn at bedtime, although it functions in terms of shaping the bust, there is a problem that it is impossible to relax and sleep due to the feeling of tightness. Furthermore, since it is common for bras worn during the day to have hooks on the back side, there is a problem that pain is felt when the hook presses the back during bedtime or sleep, and thus it is also impossible to relax and sleep. In recent years, various so-called night bras have been developed to solve such problems for wearing at bedtime. As a prior art showing such a night bra, for example, there is the following Patent Document 1.

Summary of the Invention
Problems to be Solved by the Invention
[0004] The prior art shown in the above Patent Document 1 is an invention related to women's clothing, and in women's clothing such as night bras and baby dolls, it has the merit of improving the wearing feeling and skin contact at bedtime, imparting decorativeness to enhance visuality, and further providing women's clothing with easy detachability. However, the prior art described in Patent Document 1 above has the problem that it cannot efficiently shape the bust because it only has a structure that includes left and right bust cups.
[0005] Therefore, the present invention aims to provide a night bra that solves the problems of the above-mentioned conventional technology, is capable of efficiently shaping the bust, and reduces the burden on the bust. [Means for solving the problem]
[0006] To achieve the above objectives, the night bra of the present invention is a night bra equipped with shoulder straps, wherein each of the left and right cups that enclose the bust is provided with a lifting net on its inner surface for lifting the bust vertically, the lower edge of the lifting net is sewn along the lower edge of the cup, and the top of the upper edge is positioned to fit within the width of the shoulder strap and connected to a strap, one end of which is connected to the top of the upper edge of the lifting net, and the other end is positioned to fit within the width of the shoulder strap and sewn to the lower edge on the back of the night bra, and the shoulder strap is provided with a strap insertion part on its inner surface near the top for inserting the strap, and the strap is inserted through the strap insertion part, which is the first feature of the present invention. Furthermore, in addition to the first feature described above, the night bra of the present invention has a second feature: the top of the cup is positioned to fit within the width of the shoulder band, and a strap insertion part is provided on the inner surface of the cup, outside of the top of the cup and near the top, through which the strap is inserted. Furthermore, in addition to the first or second features described above, the night bra of the present invention has a third feature: it is provided with a band-shaped underbelt made of an elastic material around the lower edge of the night bra, and a stretch-resistant tape is attached to the central region of the underbelt on the front side of the night bra. [Effects of the Invention]
[0007] According to the night bra described in claim 1, by providing a lifting net on the inner surface of each of the left and right cups that enclose the bust, the bust can be lifted and supported straight up from the bottom simply by wearing it. This makes it possible to efficiently shape the left and right busts while sleeping. In addition, because the left and right busts can be lifted and supported straight up from the bottom, no force is applied to the bust in a direction that crosses the Cooper's ligaments, thus reducing the load on the bust. This prevents the Cooper's ligaments from tearing while sleeping and prevents the bust from sagging. Furthermore, by making it a hookless bra with shoulder straps, the hooks do not press against the back at all while sleeping, allowing for a relaxed state while sleeping and improving the quality of sleep. Furthermore, the upper edge of the lifting net is positioned to fit within the width of the shoulder band and connected to the strap. One end of the strap is connected to the top of the upper edge of the lifting net, and the other end is positioned to fit within the width of the shoulder band and sewn to the lower edge on the back of the night bra. The shoulder band has a strap insertion section on the inner side near the top, through which the strap is inserted. This configuration prevents the strap from protruding from the shoulder band when worn and effectively prevents the strap from shifting from side to side. As a result, the lifting net can efficiently lift and support both breasts straight up from below, making it possible to more effectively shape the breasts during sleep. Moreover, since it is possible to further prevent the breasts from being lifted in directions other than vertical, the load on the breasts can be further reduced, making it possible to create a night bra that can further prevent the Cooper's ligaments from tearing during sleep.
[0008] Furthermore, according to the night bra described in claim 2, in addition to the effects of the configuration described in claim 1, the top of the cup is positioned to fit within the width of the shoulder band, and a strap insertion part is provided on the inner surface outside the top of the cup and near the top, and by inserting the strap through the strap insertion part, the strap can be prevented from shifting from side to side when worn even more effectively. As a result, the lifting net can be used to lift and support the left and right breasts from bottom to top more efficiently and straight.
[0009] Furthermore, according to the night bra described in claim 3, in addition to the effects of the configuration described in claim 1 or 2, the night bra is provided with a band-shaped underbelt made of elastic material around the lower edge of the bra, and a stretch-resistant tape is attached to the central area of the underbelt on the front side of the night bra. This effectively suppresses the breasts from shifting sideways (horizontally) as the underbelt stretches horizontally when worn. As a result, it becomes possible to lift and support the left and right breasts more efficiently and straight from bottom to top via the lifting net. [Brief explanation of the drawing]

[Modes for carrying out the invention]
[0011] The following description of a night bra according to an embodiment of the present invention will be provided with reference to the drawings to help understand the present invention. However, the following description is not intended to limit the present invention as described in the claims. In Figures 1 to 3, excluding the frill 3 and wire 6, the areas where two lines are arranged in parallel indicate places where the components are sewn together with what is known as rubber tape in place. Furthermore, for the sake of clarity, Figure 2(a) shows the back side fabric 2 removed, Figure 2(b) shows the strap 21 which should originally be shown as a dashed line as a solid line, and Figures 2(c) and 3(b) show the back side fabric 2 removed.
[0012] Referring to Figures 1 to 3, the night bra 1 according to an embodiment of the present invention is a hookless type night bra equipped with wide shoulder bands 2a formed from the side fabric 2. This night bra 1 consists of a side fabric 2, a frill 3, an underband 4, side pads 5, a wire 6, a side belt 7, a cup connecting piece 8, a cup 10, a lifting net 20, and a support net 30.
[0013] The aforementioned side fabric 2 forms the basic framework of the night bra 1 and is made of a thin fabric of a predetermined shape that includes breathable and stretchable shoulder bands 2a, etc. Furthermore, although not shown in detail in this embodiment, the central portions of the front side of the side fabric 2 are crossed and the upper and lower ends are sewn together so that a gap is created between the left and right cups when worn, exposing a part of the central portion of the bust. In addition, since the night bra 1 is a hookless type bra, the side fabric 2 is configured in an outer shape that can be worn by allowing the wearer to insert it into the body from the head side or the foot side, putting on the shoulder straps 2a on the shoulders, and simply extending both arms outward. In addition, as long as the fabric forming the side fabric 2 has air permeability and elasticity, various fabrics generally used as the side fabric of a night bra can be used.
[0014] The frill 3 is for adding decoration to the front side of the night bra 1, and is formed of a thin fabric with a predetermined shape having a decorative and see-through feeling. In the present embodiment, the outer side edge of the frill 3 in the horizontal direction is configured to be sewn to the side fabric 2. In addition, as long as the fabric forming the frill 3 has a decorative and see-through feeling, various fabrics generally used as the frill of a night bra can be used. Also, the shape and size of the frill 3 are not limited to those of the present embodiment and can be appropriately changed.
[0015] The underbelt 4 is for fitting and fixing the night bra 1 to the body when worn. In the present embodiment, a so-called rubber band in a belt shape formed of an elastic material is sewn to the lower end peripheral edge of the night bra 1. More specifically, it is sewn to the side fabric 2 and the frill 3 so that the underbelt 4 is disposed at the lower end peripheral edge of the night bra 1. Furthermore, as shown in Fig. 2(a), an elongation stop tape is adhered to the central region 4a on the front side of the night bra 1 in the underbelt 4. The width L of the central region 4a can be appropriately changed, but preferably, it is desirable to be about 1 cm to 1.5 cm. Of course, the member used as the underbelt 4 is not limited to a rubber band, and as long as it has elasticity, various members generally used as the underbelt of a night bra can be used.
[0016] The side pad 5 is a member for absorbing and dissipating sweat by contacting the wearer's side during wearing. In this embodiment, the side pad 5 is provided by sewing a semi-circular, thin fabric with absorbency, quick-drying property, and stretchability to the side fabric 2 and the frill 3 at the part contacting the wearer's side. Note that various fabrics commonly used as side pads for night bras can be used as the fabric forming the side pad 5.
[0017] The wire 6 is a member for preventing the night bra 1 from shifting by aligning it along the wearer's bust line during wearing. In this embodiment, a plastic wire is used as the wire 6, and the plastic wire is incorporated and sewn along the lower edge and the lower part of the side edge of the cup 10. Note that the material used as the wire 6 is not limited to a plastic wire, but considering the wearing comfort, it is desirable to use a plastic wire. Also, the width and length of the wire 6 are not limited to those of this embodiment and can be appropriately changed. Furthermore, the wire 6 is not necessarily required, and a so-called non-wire night bra without a wire may also be used.
[0018] The side belt 7 is a member for preventing the bust from flowing outward in the horizontal direction during wearing. In this embodiment, the side belt 7 is formed of the same fabric as the frill 3. Specifically, the fabric of the frill 3 is bulged outward in the horizontal direction and sewn to the side fabric 2 and the under belt 4. That is, in this embodiment, the side belt 7 is configured to also have the function of the frill 3. Note that the fabric forming the side belt 7 is not limited to that of this embodiment, and various fabrics commonly used as side belts for night bras can be used.
[0019] The cup connecting piece 8 is for connecting the cup 10 to the side fabric 2, the frill 3, and the wire 6. In this embodiment, the cup connecting piece 8 is configured to use a stretchable mesh fabric of a predetermined shape. Furthermore, as partially shown in Figure 2(c), the fabric is sewn to the outer horizontal edge of the cup 10, and also sewn to the side fabric 2, the frill 3, and the wire 6. Furthermore, the fabric used to form the cup connecting piece 8 is not limited to that of this embodiment; various fabrics commonly used as cup connecting pieces for night bras can be used.
[0020] The aforementioned cup 10 is intended to enclose the bust. In this embodiment, the cup 10 is configured to be a so-called 3 / 4 cup size cup, but the size of the cup 10 is not limited to this size, and a full cup size or a 1 / 2 cup size may also be used. In this embodiment, the outer side edge of the cup 10 in the horizontal direction is sewn to the cup connecting piece 8, the inner side edge in the horizontal direction is sewn to the side fabric 2 and the frill 3, and the lower edge is sewn to the frill 3 and the wire 6.
[0021] The lifting net 20 is a component that lifts and supports the bust vertically when worn. In this embodiment, as shown in Figure 2(a), the lifting net 20 is configured to use a stretchable triangular mesh fabric. Furthermore, the lower edge (bottom side) of the triangular mesh fabric is sewn along the lower edge of the cup 10, and the top of the upper edge is positioned to fit within the width M of the shoulder band 2a shown in Figure 2(b). In addition, the upper edge (top end) of the triangular mesh fabric is positioned within the width of the lower edge (bottom side) of the triangular mesh fabric. Furthermore, a strap 21 is connected to the top of the upper edge of the lifting net 20 via a strap connecting ring R. One end of the strap 21 is connected to the top of the upper edge of the lifting net 20, and the other end is positioned to fit within the width M of the shoulder band 2a and sewn to the lower edge of the back of the night bra 1. The strap 21 is also provided with an adjuster C that allows the length of the strap 21 to be adjusted. Note that the position where adjuster C is installed is not limited to the position in this embodiment, and can be changed as appropriate.
[0022] Furthermore, as shown in Figure 3(a), the shoulder band 2a is provided with a first strap insertion part S1 on the inner surface near the top of the shoulder band 2a for inserting the strap 21, and the strap 21 is inserted through this first strap insertion part S1. Here, "near the top of the shoulder band 2a" means a position within a range of about 2 cm from the top of the shoulder band 2a in the direction in which the shoulder band 2a extends. Furthermore, as shown in Figures 2(a) and 3(b), the top of the cup 10 is positioned within the width M of the shoulder band 2a, and outside the top of the cup 10 shown by the dashed line in Figure 3(b), but near the top, on the inner surface of the cup 10, there is a second strap insertion part S2 for inserting the strap 21, and the strap 21 is inserted through this second strap insertion part S2. Here, "near the top" means a position within approximately 3 cm from the top of the cup 10. In this embodiment, a rectangular elastic band is used as the first strap insertion portion S1 and the second strap insertion portion S2, and both ends of this elastic band are sewn to the shoulder strap 2a and the cup 10. Furthermore, the width N of the first strap insertion portion S1 shown in Figure 3(a) must be the same as or smaller than the width M of the shoulder band 2a. If it is to be smaller, for example, it can be approximately the same width as the strap 21. Furthermore, it is desirable that the length P of the first strap insertion portion S1 shown in Figure 3(a) be approximately 1 cm. Also, it is desirable that the width and length of the second strap insertion portion S2 be the same as the width N and length P of the first strap insertion portion S1.
[0023] The support net 30 is a component for supporting the lower outer portion of the bust when worn. In this embodiment, a thin, stretchable mesh fabric is folded in half into a roughly triangular shape, with the outer side edges sewn to the cup 10 and the lower edge sewn to the wire 6. The fabric used to form the support net 30 is not limited to that of this embodiment and can be changed as appropriate. Furthermore, the shape and size of the support net 30 are not limited to those of this embodiment and can be changed as appropriate.
[0024] Next, with reference to Figure 3(b), the movement and function of the lifting net 20 when wearing the night bra 1 of the present invention, which has the configuration described above, will be explained. As shown in Figure 3(b), when wearing the night bra 1, the straps 21 are stretched in the direction indicated by the black arrows. Consequently, the lifting net 20 is pulled straight up from below, causing the left and right breasts 10 to be lifted and held straight up (vertically) from below within the cups 10.
[0025] The night bra 1 of the present invention, having the above configuration, provides the following effects.
[0026] Each of the left and right cups 10 that enclose the bust is equipped with a lifting net 20 on the inner side to lift the bust vertically. Simply by wearing it, the bust can be lifted and supported straight from bottom to top. This makes it possible to maintain the shape of the bust while sleeping. Furthermore, the Cooper's ligaments located inside the breasts are tissues that support the entire breast to prevent sagging. Composed mainly of collagen, these ligaments are not very elastic and are prone to stretching or tearing under load. However, the lifting net 10 allows the breasts to be lifted straight up from bottom to top, preventing force from being applied to the breasts in a direction that crosses the Cooper's ligaments, thereby reducing the load on the breasts. Therefore, it is possible to effectively prevent excessive force from being applied to the Cooper's ligaments, preventing them from tearing during sleep or bedtime, and preventing the breasts from sagging. In addition, by using a hookless bra with shoulder straps 2a, the hooks will not press against the back at all while sleeping, allowing you to maintain a relaxed state while sleeping and potentially improving the quality of your sleep. Furthermore, the upper end of the lifting net 20 is positioned to fit within the width M of the shoulder band 2a and connected to the strap 21. One end of the strap 21 is connected to the top of the upper edge of the lifting net 20, and the other end is positioned to fit within the width M of the shoulder band 2a and sewn to the lower edge on the back of the night bra 1. The shoulder band 2a has a first strap insertion part S1 on its inner surface near the top for inserting the strap 21, and by inserting the strap 21 through the first strap insertion part S1, it is possible to prevent the strap 21 from protruding from the shoulder band 2a when worn, and to effectively prevent the strap 21 from shifting from side to side. This effect is made even more effective by providing a first strap insertion part S1 on the inner surface near the top of the shoulder band 2a, through which the strap 21 is inserted, so that the first strap insertion part S1 is pressed toward the wearer's shoulder by the shoulder band 2a. This allows the lifting net 20 to efficiently lift and support both breasts straight up from bottom to top, making it possible to more efficiently shape the breasts during sleep. Furthermore, since the breasts are not lifted in any direction other than vertical, the load on the breasts can be further reduced, making it possible to create a night bra 1 that can more effectively prevent the Cooper's ligaments from tearing during sleep. This effect is made even more pronounced when the width N of the first strap insertion part S1 shown in Figure 3(a) is approximately the same as the width of the strap 21.
[0027] Furthermore, the top of the cup 10 is positioned to fit within the width of the shoulder band 2a, and a second strap insertion part S2 for inserting the strap 21 is provided on the inner side, outside the top of the cup 10 and near the top. By inserting the strap 21 through the second strap insertion part S2, the strap 21 can be prevented from shifting from side to side when worn. This allows the lifting net 20 to lift and support both sides of the bust more efficiently and straight from bottom to top. This effect is further enhanced when the width of the second strap insertion part S2 is approximately the same as the width of the strap 21. In addition, by providing two strap insertion parts, a first strap insertion part S1 and a second strap insertion part S2, the combined effect of the first strap insertion part S1 and the second strap insertion part S2 makes the above effect even more reliable and precise.
[0028] Furthermore, the night bra 1 is equipped with a band-shaped underbelt 4 made of elastic material around the lower edge, and a stretch-resistant tape is attached to the central area 4a on the front side of the underbelt 4. This effectively prevents the bust from shifting sideways (horizontally) as the underbelt 4 stretches horizontally when worn. As a result, the left and right busts can be lifted and supported more efficiently and straight from bottom to top via the lifting net 20.
[0029] Furthermore, by providing adjusters C on each of the left and right straps 21 connected to the left and right lifting nets 20, it is possible to adjust the amount of lift provided by the lifting nets 20 to match the difference in bust size between the left and right sides, which is common among many people.
[0030] Furthermore, by creating a gap between the left and right cups 10 when worn, exposing a portion of the central part of the bust, it becomes possible to visually confirm the effect when adjusting the size of the left and right busts using adjuster C. Therefore, it becomes possible to adjust the difference in size between the left and right busts more efficiently. Furthermore, creating a gap between the left and right cups 10 improves breathability during sleep and bedtime. In addition, by creating a gap between the left and right cups 10 when worn, exposing a portion of the central part of the bust, it is possible to create a night bra 1 that can further enhance the wearer's attractiveness.
[0031] Furthermore, the support net 30 provides firm support to the lower outer part of the bust when worn, making it possible to further shape the left and right sides of the bust.
[0032] In the night bra 1 according to the embodiment of the present invention described above, the strap insertion portion is provided in two locations. However, the configuration is not necessarily limited to this, and it is also possible to provide only one of the first strap insertion portions S1, or to provide three or more locations including the two mentioned above. However, it is necessary that the strap insertion portions be positioned so as to fit within the width M of the shoulder band 2a. Furthermore, the shape and size of the lifting net 20 are not limited to those of this embodiment and can be changed as appropriate. However, the top of the upper edge of the lifting net 20 must be positioned so that it fits within the width M of the shoulder band 2a. In addition, when the lifting net 20 is made of a triangular mesh fabric, the upper edge (top end) of the triangular mesh fabric must be positioned within the width of the lower edge (bottom side) of the triangular mesh fabric. Furthermore, while the night bra 1 according to the embodiment of the present invention described above uses a hookless night bra, the invention is not necessarily limited to this configuration. For example, a hooked night bra with hooks on the back of the wearer may also be used. In this case, "the lower edge on the back of the night bra" in the present invention refers to the lower edge on the back of the night bra when the hooks are fastened. [Industrial applicability]
[0033] According to the present invention, it is possible to shape the bust and reduce the burden on the bust, making it useful in the industrial field related to night bras and giving it great potential for industrial application. [Explanation of Symbols]
