Abstract
Description
Technical Field
[0001] The present invention relates to a men's long haori, and particularly to a structure that makes it easy to stably position the collar at a desired location.
Background Art
[0002] Conventional men's long haoris are composed of a long haori main body having a body and left and right sleeve parts, and a string provided separately from the long haori main body. By tightening the separate string at the wearer's chest, the body of the long haori main body is made stable with respect to the wearer. Therefore, conventional men's long haoris tend to cause discomfort to the wearer by extremely strongly pressing the wearer's chest. Furthermore, in conventional men's long haoris, the body of the long haori main body is likely to become loose, and over time, problems such as the collar provided on the body shifting or floating on the collar are likely to occur. In addition, conventional men's long haoris often require re-tailoring to accommodate changes in the wearer's body shape, and have a structure that makes it difficult to flexibly respond to changes in body shape. In addition to these, conventional men's long haoris are difficult to accurately align the upper left part of the collar in the body (referring to the upper left side as seen from the wearer), and this is particularly prominent when beginners wear them. Regarding improvements to men's long haoris, various studies have been made conventionally (for example, refer to Patent Document 1). However, this type has a problem that the structure of the long haori main body is extremely complicated, and furthermore, since it uses a hook-and-loop fastener, it is likely to damage expensive fabrics and embroidery.

Summary of the Invention
[0004] This invention was made in view of the above circumstances, and aims to provide a men's nagajuban (undergarment for formal occasions) that has a simple structure that is easy for the user to handle, while also effectively preventing the garment from becoming disheveled by ensuring that the collar stays in the appropriate place on the wearer. [Means for solving the problem]
[0005] The invention described in claim 1 is a men's nagajuban comprising a body having left and right front panels and a back panel continuous with the outer edges of the left and right front panels, left and right sleeves connected to the body, a left cord whose base end is sewn to the inner end of the left front panel, and a right cord whose base end is sewn to the inner end of the right front panel, wherein a cord insertion hole is provided only at the boundary between the left front panel and the back panel, located below the left sleeve, through which the free end of the right cord can be inserted, and the right cord is configured to be able to be tied with the left cord after the free end of the right cord has been inserted into the cord insertion hole and passed through the outer surfaces of the back panel and the right front panel. [Effects of the Invention]
[0006] This invention provides a men's nagajuban (undergarment for formal occasions) that has a simple structure that is easy for the user to handle, while also effectively preventing the garment from becoming disheveled by ensuring that the collar stays in the appropriate place on the wearer. [Brief explanation of the drawing]
[0007] [Figure 1] A schematic front view showing one embodiment of the present invention. [Figure 2] A schematic front view of the same embodiment. [Modes for carrying out the invention]
[0008] The men's nagajuban (undergarment) of this invention has the following components. A men's nagajuban (undergarment) comprises a body A having left and right front panels 1 and 2, and a back panel 3 that is continuous with the outer edges of the left and right front panels 1 and 2; left and right sleeves 4 and 5 attached to body A; a left tie 6 whose base end is sewn to the inner end of the left front panel 1; and a right tie 7 whose base end is sewn to the inner end of the right front panel 2. Furthermore, in the men's nagajuban (undergarment), a cord insertion hole H is provided only at the boundary between the left front panel 1 and the back panel 3, which is located below the left sleeve 4, through which the free end of the right cord 7 can be inserted. In the men's nagajuban (undergarment), the right cord 7, which is threaded through the back of the left front panel 1, is inserted through the cord insertion hole H, and then the free end of the right cord 7 passes through the outer surfaces of the back panel 3 and the right front panel 2, and is configured to be tied with the left cord 6. The cord insertion hole H is located at the left side seam of the body A of a men's nagajuban (the boundary between the left front body 1 and the back body 3), and its opening width is set within a range of 5 to 20 cm downward from the underarm position. Here, if the opening width of the cord insertion hole H is less than 5 cm, it becomes too narrow as a passage for the right cord 7, making insertion and adjustment difficult. On the other hand, if the opening width of the cord insertion hole H exceeds 20 cm, the stability of the lower part of the left front panel 1 decreases. Furthermore, the cord insertion hole H is treated to prevent fraying, for example, by stitching the edge of the fabric at the opening, but the passage itself is not blocked. The left string 6 and the right string 7 are set to a length of approximately 120 cm, for example. The left string 6 and the right string 7 are sewn near the collar tip (slightly above the collar tip). The left string 6 and the right string 7 are pulled at the hip bone level, wrapped around to the back, and the free end portion (the tip portion) is tied in front of the wearer. This causes the collar to be pulled from both sides, fixed at the hip bone, and the upper left portion to naturally settle (the upper left portion of the garment becomes more stable). In this embodiment, the collar will not shift for extended periods, and the upper left portion of the garment will be securely held in place. Furthermore, this embodiment avoids constricting the wearer's chest too much, thus minimizing discomfort for the person sitting. Furthermore, in this embodiment, by adjusting the left string 6 and the right string 7 attached to the body A, it is possible to flexibly adapt to changes in the wearer's body shape, and long-term use is possible without the need for size adjustments. Furthermore, the cord insertion holes H are located only at the boundary between the left front panel 1 and the back panel 3, below the left sleeve portion 4, so they are not noticeable when the garment is folded.
