[0018] Hereinafter, a brassiere according to an embodiment of the present invention will be described. The brassiere of this embodiment has a cup size adjustment function, which means that the user can easily adjust the cup size to fit the individual user's body shape. Furthermore, the brassiere of this embodiment has removable pads. That is, the structure allows the pads to be easily removed and put back in, so that the pads can be washed and kept clean.
[0019] Furthermore, the brassiere of this embodiment allows for a variety of designs. In other words, by allowing for size adjustment and removable pads, a wider variety of designs can be realized, increasing the options available to meet the user's preferences. This allows for a comfortable and functional brassiere to be provided, improving user satisfaction.
[0020] FIG. 1 is a front view of a brassiere 11 according to an embodiment of the present invention. FIG. 2 is a diagram for explaining the arrangement of linear members exposed on the back surface of brassiere 11 shown in FIG. FIG. 3 is a diagram for explaining the pattern of cavities that define the size of the cup portion of brassiere 11 shown in FIG. FIG. 4 is a rear view of the brassiere 11 shown in FIG. FIG. 5 is a diagram illustrating the opening for inserting and removing a pad formed on the back surface of brassiere 11 shown in FIG. FIG. 6 is a diagram illustrating the brassiere 11 shown in FIG. 1 in a state where the knot of the linear member is undone.
[0021] As shown in FIGS. 1 to 6, brassiere 11 has two cup portions 21 and 24, each of which covers at least a part of the breast. The back of the brassiere 11 is provided with a back belt 31 for holding the cup portions 21, 24 around the breasts when worn by the user.
[0022] Additionally, around the periphery of each of the cup portions 21 and 24, curved cavities 41 and 43 are formed along the outer edges of the cup portions so as to surround the cup portions 21 and 24, respectively.
[0023] The cavities 41 and 43 house portions of the linear members 51 and 53, respectively. The first ends 61, 63 of the linear members 51, 53 are located near the second ends 71, 73 within the cavities 41, 43. The first other end portions 81 and 83 of the linear members 51 and 53 are located outside the cavities 41 and 43.
[0024] The brassiere 11 is structured so that the size of the cup portions 21, 24 can be adjusted (made smaller) by pulling the first other end portions 81, 83 exposed to the outside of the linear members 51, 53 with fingers or the like. By expanding the cavities 41, 43 outward with hands or the like, a part of the first other end portions 81, 83 enters the cavities 41, 43, and the size of the cup portions 21, 24 can be adjusted (enlarged).
[0025] That is, in brassiere 11, the shape of cup portions 21, 24 is determined by the length of the portion of linear members 51, 53 on first other end portions 81, 83 sides of cavities 41, 43 that protrudes from second other end portions 45, 47 sides.
[0026] When the first other end portions 81, 83 of the linear members 51, 53 are pulled in a direction away from the second other end portions 45, 47 of the cavities 41, 43, the size of the cup portion is reduced.
[0027] As shown in FIG. 1, a first other end 81 of the linear member 51 of the cup portion 21 and a first other end 83 of the linear member 53 of the cup portion 23 are connected near the center of the front surface side. When adjusting the size of the cup portions 21, 24, the user unties the knot between the first other end portion 81 of the linear member 51 of the cup portion 21 and the first other end portion 83 of the linear member 53 of the cup portion 23, as shown in Fig. 6. This allows the size of the cup portions 21, 24 to be adjusted while pulling the linear members 51, 53.
[0028] Bra 11 has first openings 91, 93 through which linear members 51, 53 pass from the rear surface to the front surface, and linear members 51, 53 are exposed between cavities 41, 43 on the rear surface side and first openings 91, 93.
[0029] The cup portions 21 and 24 are provided with pad-accommodating spaces 25 and 27, respectively. Pad insertion / removal openings 101 and 103 are formed on the rear surface side so that the pads 35 and 37 can be inserted into and removed from the pad accommodating spaces.
[0030] Also, openings 101 and 103 for inserting and removing pads are formed at positions corresponding to the cavities 41 and 43 exposed on the rear surface of the brassiere 11.
[0031] The brassiere 11 is knitted as a single piece without any seams. The brassiere 11 is made of a material such as polyester, nylon, acrylic, or rayon. The pads 35 and 37 are made of a material that has higher water absorption properties than the other materials.
[0032] Below, we will explain how to use Bra 11. [Cup size adjustment for 21 and 24] For example, after purchasing brassiere 11, the user puts on brassiere 11 by placing both breasts in cup portions 21, 24 and sandwiching them with back belt 31. Next, as shown in FIG. 6, the user unties the knot between the first other end portion 81 of the linear member 51 of the cup portion 21 and the first other end portion 83 of the linear member 53 of the cup portion 23. This allows the sizes of the cup portions 21 and 24 to be adjusted while pulling the linear members 51 and 53.
[0033] The user pulls the first other end 81 of the linear member 51 of the cup portion 21 and the first other end 83 of the linear member 53 of the cup portion 23 with their fingers or the like on the front side to shape the cavities 41, 43 to fit the shape of the breast. Then, at the position of the fitted shape, the user ties the linear member 51 and the linear member 52 together to fix the shape in that position.
[0034] This allows the cup portions 21 and 24 to be adjusted to the shape of the user's breasts.
[0035] [Washing Pads 35 and 37] When washing the brassiere 11, the user removes the stored pads 35, 37 from the pad storage spaces 25, 27 through the pad insertion / removal openings 101, 103 shown in FIG. After the pads 35, 37 are washed in a washing machine, the pads 35, 37 are inserted into the pad accommodating spaces 25, 27 through the pad insertion / removal openings 101, 103.
[0036] This allows the pads 35, 37 to be washed and kept clean.
[0037] As described above, brassiere 11 allows the cup shape to be adjusted to fit the shape of each user's breasts, providing a comfortable fit.
[0038] Furthermore, since brassiere 11 has a structure in which the pad can be removed or put in, the pad can be washed or replaced, making it possible to always use a clean pad.
[0039] The present invention is not limited to the above-described embodiments. That is, those skilled in the art may make various modifications, combinations, subcombinations, and substitutions of the components of the above-described embodiments within the technical scope of the present invention or its equivalents.
[0040] For example, in the above-described embodiment, in addition to the shape adjusting structure of the cup portion, the replaceable structure of the pads 35, 37 is illustrated, but the replaceable structure of the pads 35, 37 does not necessarily have to be provided.
[0041] Furthermore, the positions of the pad insertion / removal openings 101 and 103 are not particularly limited.
[0042] In the above-described embodiment, the linear members are tied at the front, but they may be tied at the side or back. [Industrial Applicability]
