Description

Technical Field

[0001] The present invention relates to a cloth button and a garment provided with such a cloth button.

Background Art

[0002] In a childcare setting, since clothes are easily soiled in various situations, most childcare workers wear aprons. In a general apron, one string is attached to each of the left and right sides near the waist, and the user wears the apron by tying these strings in a bow behind the person's body (back). The bow knot has the characteristics of being easy to tie and untie, and is a very convenient knotting method in the ordinary use of an apron. However, in a childcare setting, there are often situations where quick and large movements are required while wearing an apron, and the strings often come undone in unexpected situations. In some cases, there is also a risk that children may get caught on the untied strings, and there is a desire to avoid using strings for childcare worker aprons.

[0003] As an apron that does not use strings, there is also a slip-on type that is worn through the upper arm, head, and torso. However, since it takes time to put on and take off the apron, it can be troublesome for childcare workers who are pressed for time to deal with children.

[0004] On the other hand, as an apron for childcare workers, there is one that uses resin buttons to fasten the seam at the back (rear) (for example, Patent Document 1). By using buttons, it becomes easier to put on and take off the apron, and there is no worry that children will get caught as with strings.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The inventors considered using fabric buttons to create a safer and more functional apron. For example, they wanted to prevent children from feeling pain from buttons bumping into the apron, and to ensure that buttons that fall off the apron and land on the floor are safe even if children put them in their mouths. They also considered the need for fabric buttons that are flat and secure, while still being difficult to detach when fastened, to ensure the ease of movement of childcare workers who may be moving around a lot.

[0019] According to the fabric button according to the first aspect of the present invention, in a state of being connected to a second fabric by a connecting portion formed on one end side of a first fabric, when a locking portion formed on the other end side of the first fabric is inserted into a hole portion opened in a third fabric, the locking portion is locked to the hole portion. Thereby, the seam between the second fabric and the third fabric is fastened by the fabric button. Further, the locking portion is folded at the other end portion of the first fabric located on the other end side so that the other end of the first fabric is located between the first fabrics, and the folded first fabric and the first fabrics on both sides sandwiching the folded first fabric are sewn together. That is, since the locking portion is configured only by folding and sewing the first fabric, it can be formed flat. On the other hand, even if the flat locking portion inserted into the hole portion is pulled in the direction of coming off, the portion where the first fabric is sewn catches and is surely locked to the hole portion, so that it can be made difficult to come off in the situation where the seam is fastened. Thereby, there is an effect that it can be made flat and difficult to come off in the situation where the seam is fastened.

[0020] According to the fabric button according to the second aspect, in addition to the effect exhibited by the fabric button according to the first aspect, the following effect is exhibited. That is, the locking portion is sewn at least at a position substantially parallel to a plurality of substantially parallel folded portions formed by folding the first fabric. Thereby, even if the button is pulled in the direction of coming off, the range caught by the hole portion due to the sewing performed substantially parallel to the folded portion becomes wider, and there is an effect that it can be made more surely difficult to come off in the situation where the seam is fastened.

[0021] The third embodiment of the fabric button provides the following effects in addition to those of the second embodiment of the fabric button. Specifically, the stitching at the locking portion, which is performed approximately parallel to the folded portion, is performed at a position where the distance between the stitching position and the first folded portion, which is the furthest from the other end of the first fabric, is greater than or equal to the distance between the stitching position and the second folded portion, which is the second furthest from the other end of the first fabric. As a result, sufficient distance is maintained between the first folded portion and the stitching position, making it easier for the user to grasp that portion with their fingers and allowing them to easily insert the button into the buttonhole without stress.

[0022] The fabric button according to the fourth embodiment provides the following effect in addition to the effect of the fabric button according to the second or third embodiment. Specifically, the first fabric is sewn to the locking portion not only at a position substantially parallel to the folded portion, but also along the first line portion on the side of the first line portion, which is one of the first and second line portions that form the outer edge of the locking portion and connects the first and second folded portions. As a result, even if force is applied to the locking portion, the stitching of the locking portion is less likely to come undone, and the locking portion can be made stronger.

[0023] The fabric button according to the fifth embodiment provides the following effect in addition to the effect of the fabric button according to the fourth embodiment. Specifically, the stitching at the locking portion is performed at least substantially parallel to the folded portion, and not along the second line portion on the side of the second folded portion, so that when removing the locking portion from the hole, the locking portion can be easily removed from the vicinity of the unstitched second line portion.

[0024] The cloth button according to the sixth aspect exhibits the following effects in addition to the effects exhibited by the cloth buttons according to any one of the second to fifth aspects. That is, the sewing performed substantially parallel to the folded-back portion at the locking portion is carried out at a position where the distance between the sewing position and the first folded-back portion, which is the folded-back portion farthest from the other end of the first fabric, is 5 mm or more. As a result, the portion between the first folded-back portion and the sewing position has a length sufficient to grasp that portion with a finger, so that the user can easily insert that portion into the hole of the button without stress.

[0025] According to the clothing according to the seventh aspect, the seam between the second fabric and the third fabric is fastened by a cloth button. As a result, it is possible to suppress the pain caused by the button and ensure safety even if the button comes off the clothing. Further, according to the cloth button, in a state where it is connected to the second fabric by a connecting portion formed on one end side of the first fabric, when a locking portion formed on the other end side of the first fabric is inserted into a hole formed in the third fabric, the locking portion is locked to the hole. As a result, the seam between the second fabric and the third fabric is fastened. Further, the locking portion is formed by folding the other end of the first fabric so that the other end of the first fabric is located between the first fabrics at the other end portion of the first fabric located on the other end side, and sewing the folded first fabric and the first fabrics on both sides sandwiching the folded first fabric. That is, since the locking portion is formed only by folding and sewing the first fabric, it can be formed flat. On the other hand, even if the flat locking portion inserted into the hole is pulled in the direction of coming off, the portion where the first fabric is sewn catches and is securely locked to the hole, so that it can be made difficult to come off in the situation where the seam is fastened. As a result, there is an effect that it can be made flat and difficult to come off in the situation where the seam is fastened.

[0026] According to the clothing according to the eighth aspect, in addition to the effect exhibited by the clothing according to the seventh aspect, the following effect is exhibited. That is, the hole into which the locking portion of the cloth button is inserted is composed of a short side and a long side, and the long side is formed along the seam between the second fabric and the third fabric. Thereby, even if the inserted locking portion is pulled in a direction perpendicular to the direction of the seam, the locking portion is locked to the long side of the hole, so that there is an effect that it is possible to surely prevent the cloth button from coming off.

[0027] According to the clothing according to the ninth aspect, in addition to the effect exhibited by the clothing according to the seventh or eighth aspect, the following effect is exhibited. That is, the sewing performed substantially parallel to the folded-back portion at the locking portion is such that the distance between the position of the sewing and the first folded-back portion, which is the farthest from the other end of the first fabric as the folded-back portion, is the distance between the position of the sewing and the second folded-back portion, which is the second farthest from the other end of the first fabric. In addition, the hole is opened in the third fabric such that the distance between the end of the third fabric located on the seam side with the second fabric and the hole is not less than the distance between the position of the sewing performed substantially parallel to the folded-back portion and the first folded-back portion. Thereby, the distance between the first folded-back portion and the sewing position at the locking portion is sufficiently maintained, and the distance between the end of the third fabric on the seam side with the second fabric and the hole in the third fabric is sufficiently maintained, so that the user can easily grasp those portions with fingers and can easily insert the button into the hole of the button without stress.

[0028] According to the clothing according to the tenth aspect of the present invention, in addition to the effect exhibited by the clothing according to any one of the seventh to ninth aspects, the following effect is exhibited. That is, the hole is opened in the third fabric such that the distance between the end of the third fabric located on the seam side with the second fabric and the hole is 5 mm or more. Thereby, the distance between the end of the third fabric on the seam side with the second fabric and the hole in the third fabric is sufficiently maintained, so that the user can easily grasp that portion with fingers and can easily insert the button into the hole of the button without stress.

[0029] According to the 11th aspect of the present invention, an apron can achieve the effects of the garment according to any of the 7th to 10th aspects. [Brief explanation of the drawing]

[0031] Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings. The embodiments described below are all preferred specific examples of the present invention. Therefore, the numerical values, shapes, materials, components, arrangement positions of components, and connection configurations shown in the following embodiments are examples and are not intended to limit the present invention. Accordingly, among the components in the following embodiments, those not described in the independent claims representing the highest-level concept of the present invention will be described as optional components. Furthermore, in each figure, substantially identical components are denoted by the same reference numerals, and redundant explanations are omitted or simplified.

[0032] First, with reference to Figures 1 to 3, we will describe the fabric button 10 (hereinafter simply referred to as "button 10") according to one embodiment of the present invention, and an apron 1, which is an example of a garment equipped with the button 10. Figure 1 is a schematic diagram showing the entire apron 1 equipped with the button 10, and Figure 2 is an enlarged view of the area on the apron 1 where one button 10 is provided. Figure 3(a) is a schematic cross-sectional view of the button 10, and Figure 3(b) is a schematic cross-sectional view of the apron 1 and the button 10 in the state in which the button 10 attached to the apron 1 is fastened to a buttonhole 5 opened in the apron 1.

[0033] Please note that in the schematic cross-sectional view of the button 10 (first fabric 6) shown in Figure 3 and Figures 4 and 5 (described later), the scale in the length direction (left-right direction on the paper) and the thickness direction (top-bottom direction on the paper) are not the same, prioritizing clarity, and the scale in the thickness direction is drawn larger. In particular, in the schematic cross-sectional view, the folded portion 13 (first folded portion 13a to fourth folded portion 13d) is shown as being folded with a predetermined width in the top-bottom direction on the paper, but in reality, each folded portion 13 is folded in a valley fold or mountain fold with the vertex. Also, please note that in all drawings, the size of the locking portion 11 for the button 10 is drawn larger for the sake of clarity.

[0034] As shown in Figure 1, Apron 1 is constructed by sewing together a second fabric 2 that covers the user's back and a third fabric 3 that covers the user's front, on the right side when viewed from the user's front. The second fabric 2 and the third fabric 3 may be made of the same material or different materials. Furthermore, these materials may be made of natural fibers, or synthetic fibers may be used in either one or both of them.

[0035] The user puts on the apron 1 by putting their head through the neckline formed across the second fabric 2 and the third fabric 3 at the top of the apron 1, and their arms through the armholes formed across the second fabric 2 and the third fabric 3 on each side of the apron 1. At this time, the seam 4 where the second fabric 2 and the third fabric 3 meet is formed on the left side when viewed from the front of the user. The apron 1 has three buttons 10 arranged vertically below the left armhole to fasten these seams 4.

[0036] In this way, the buttons 10 are located on the side of the apron 1, specifically from the armpit to the side of the wearer's torso, allowing the wearer to easily fasten the buttons 10. Furthermore, even if children bump into the wearer with force, it is possible to prevent them from hitting the buttons 10 located on the side of the apron 1.

[0037] The number of buttons 10 does not necessarily have to be three; the required number of buttons 10 may be provided depending on the length of the seam 4, the required strength of the garment (apron 1), etc.

[0038] Button 10 is a cloth button made of a rectangular first fabric 6, for example, measuring 100 mm in length and 20 mm in width. Since the apron 1 is fastened at the seam 4 of the second fabric 2 and the third fabric 3 by the cloth button 10, it is possible to suppress the pain that can be felt with resin buttons or snap buttons, and even if the button 10 comes off the apron 1, safety can be ensured, for example, by ensuring that it is safe even if a child puts the detached button 10 in their mouth.

[0039] The size of the first fabric 6 is merely an example and may be determined based on the size of the button 10 required by the apron 1. Furthermore, the first fabric 6 may be made of natural fibers or synthetic fibers, and may be made of the same material as the second fabric 2 or the third fabric 3, or it may be made of a different material than the second fabric 2 and the third fabric 3. If the first fabric 6 is made of the same material as the second fabric 2 or the third fabric 3, it is also possible to make the button 10 using scraps of the second fabric 2 or the third fabric 3. This makes it possible to create an environmentally friendly button 10 by reducing raw materials and waste.

[0040] As shown in Figures 2 and 3, the button 10 has a connecting portion 12 and a locking portion 11 formed on the first fabric 6, and the connecting portion 12 and the locking portion 11 are connected via the remaining first fabric 6.

[0041] As shown in Figures 3(a) and (b), the connecting portion 12 is formed on one end 6a of the short side of the rectangular first fabric 6 and is the part that connects to the second fabric 2 of the apron 1. The button 10 is sewn to the second fabric 2 at the connecting portion 12 by a square-shaped sewing portion 12a, for example as shown in Figure 2. Because the button 10 is sewn in a square shape, it is firmly fixed (connected) to the second fabric 2, so that the button 10 does not easily come off due to the thread unraveling or the like.

[0042] Furthermore, the shape of the sewn portion 12a can be arbitrary, as long as the button 10 is connected to the second fabric 2 so that it does not come off easily. For example, it can be a U-shape, an X-shape, a single line or multiple parallel lines parallel to one end 6a, a single line or multiple parallel lines perpendicular to one end 6a, a single line or multiple parallel lines diagonally to one end 6a, or any combination of two or more of these, including a square shape.

[0043] As shown in Figures 2 and 3, the locking portion 11 is formed on the other end 6b of the short side of the rectangular first fabric 6, that is, on the side opposite to the end 6a where the connecting portion 12 is formed, and when inserted into the buttonhole 5 opened in the third fabric 3, it is the portion that locks into the buttonhole 5. The buttonhole 5 corresponds to the hole portion of the present invention and, as shown in Figure 2, is composed of a long side 5a and a short side 5b. The buttonhole 5 is opened and formed in the third fabric 3 such that the long side 5a is along the joint 4 between the second fabric 2 and the third fabric 3, for example, substantially parallel to the end 3a of the third fabric 3 located on the side of the joint 4 with the second fabric 2. Here, substantially parallel includes not only perfect parallelism but also a range that can be considered substantially parallel.

[0044] As shown in Figure 3(a), the locking portion 11 is formed by folding the other end of the first fabric 6 located on the other end 6b side so that the other end 6b of the first fabric 6 is positioned between the first fabric 6s, and then sewing the folded first fabric 6 and the first fabric 6s on both sides that sandwich the folded first fabric 6 with the sewing portion 21.

[0045] Here, FIG. 4 is a diagram schematically showing the process of forming the locking portion 11 of the button 10. FIG. 4(a) is a front view and a schematic cross-sectional view of the first fabric 6 before forming the locking portion 11. FIG. 4(b) is a front view and a schematic cross-sectional view of the first fabric 6 in a state of being folded back once. FIG. 4(c) is a front view and a schematic cross-sectional view of the first fabric 6 in a state of being folded back twice. FIG. 4(d) is a front view and a schematic cross-sectional view of the first fabric 6 with the doubly folded-back portion sewn to form the locking portion 11. In the following description, the rectangular plane of the first fabric 6 is regarded as the front. The locking portion 11 is formed according to the process shown in FIG. 4.

[0046] That is, as shown in FIG. 4(a), a plurality of folding portions 13, which are the folding positions of the first fabric 6, are provided at the portion of the first fabric 6 that will become the locking portion 11. In the example shown in FIG. 4, as the folding portions 13, a first folding portion 13a that is farthest from the other end 6b of the first fabric 6 and a second folding portion 13b that is second farthest from the other end 6b of the first fabric 6 are provided. The distance from the other end 6b of the first fabric 6 to the first folding portion 13a is set to, for example, 35 mm, and the distance from the other end 6b of the first fabric 6 to the second folding portion 13b is set to, for example, 15 mm.

[0047] When forming the locking portion 11 on the first fabric 6, first, starting from the state shown in FIG. 4(a), the first fabric 6 is valley-folded so as to be folded on the front side at the second folding portion 13b. As a result, as shown in FIG. 4(b), the first fabric 6 is folded such that the other end 6b side is folded into a J shape. That is, the first fabric 6 is folded so that the second folding portion 13b is located at the end and the other end 6b faces the one end 6a side of the first fabric 6.

[0048] Next, from the state shown in Figure 4(b), the first fabric 6 is further folded in a valley fold at the first fold portion 13a so that it is folded towards the front. As a result, the other end 6b of the first fabric 6 is folded in a "no" shape, as shown in Figure 4(c). That is, the other end of the first fabric 6 located on the other end 6b side is folded so that the other end 6b of the first fabric 6 is positioned between the first fabric 6. Then, the outer edge of the locking portion 11 is formed by the first fold portion 13a, the second fold portion 13b, the first line portion 14a connecting one end of the first fold portion 13a and one end of the second fold portion 13b, and the second line portion 14b connecting the other end of the first fold portion 13a and the other end of the second fold portion 13b.

[0049] Here, the first folded portion 13a and the second folded portion 13b are provided to be substantially parallel to each other. Furthermore, each folded portion 13 (the first folded portion 13a and the second folded portion 13b) is provided to be substantially parallel to the other end 6b of the first fabric 6. Note that "substantially parallel" includes not only perfectly parallel but also a range that can be considered substantially parallel to the extent that the effects described below are obtained.

[0050] In other words, by making these approximately parallel, as shown in Figure 4(c), the locking portion 11 formed by folding the first fabric 6 at the folded portion 13 is formed so that, when the first fabric 6 is viewed from above, it does not protrude from the rectangular surface of the first fabric 6 before folding, but rather stacks on top of that surface. That is, since the locking portion 11 is formed by several layers of the first fabric 6 at any point, it can be constructed to have a certain degree of rigidity and be sturdy. In addition, when the locking portion 11 is inserted into the buttonhole 5, its thickness and / or rigidity make it difficult for it to come out of the buttonhole 5.

[0051] Next, as shown in Figure 4(d), the locking portion 11, which has an outer edge formed as shown in Figure 4(c), is formed by sewing the first fabric 6 folded in the locking portion 11 and the first fabric 6 on both sides that sandwich the folded first fabric 6 at the sewing portion 21 which is set to be approximately parallel to the folded portion 13 (first folded portion 13a and second folded portion 13b), thereby forming the locking portion 11.

[0052] In this way, the locking portion 11 can be easily formed flat simply by folding and sewing the first fabric 6. When the button 10 is pulled in the direction that would cause the locking portion 11 to come off (to the right in Figure 3(b)) when the flatly formed locking portion 11 is inserted into the buttonhole 5 opened in the third fabric 3, the sewn portion 21 of the first fabric 6 catches on it and securely locks into the buttonhole 5. As a result, the button 10 is less likely to come off when fastening the joint 4 of the second fabric 2 and the third fabric 3.

[0053] Furthermore, even if the button 10 is pulled in a direction that causes the locking portion 11 inserted into the buttonhole 5 to come loose (to the right in Figure 3(b)), the sewing portion 21, which is set to be approximately parallel to the folded portion 13 (first folded portion 13a and second folded portion 13b), widens the area over which it can catch on the buttonhole 5, making it more secure and less likely to come undone when the seam 4 is fastened.

[0054] Furthermore, as described above, the buttonhole 5 into which the locking portion 11 is inserted is formed in the third fabric 3 such that its long side 5a aligns with the seam 4 between the second fabric 2 and the third fabric 3 (for example, approximately parallel to the end portion 3a of the third fabric 3 located on the side of the seam 4 with the second fabric 2). As a result, even if the locking portion 11 inserted into the buttonhole 5 is pulled in a direction perpendicular to the direction of the seam 4 (to the right in Figures 2 and 3(b)), the locking portion 11 is secured to the long side 5a of the buttonhole 5, thus reliably preventing the fabric button 10 from coming off.

[0055] Furthermore, since the locking portion 11 is formed by folding the other end 6b of the first fabric 6 so that it is positioned between the first fabric 6, as shown in Figure 3(a), the other end 6b is covered by the first fabric 6 and is not exposed. Therefore, even if the locking portion 11 is repeatedly subjected to pulling force or repeatedly grasped with fingers to remove it from the buttonhole 5, it is possible to prevent the other end 6b from unraveling and thus preventing the button 10 from losing its function.

[0056] Here, as shown in Figure 4(d), the stitching portion 21, which is approximately parallel to the folded portion 13 in the locking portion 11, is set at a position where the distance d1 between the stitching portion 21 and the first folded portion 13a is equal to or longer than the distance d2 between the stitching portion 21 and the second folded portion 13b. As a result, the distance d1 between the first folded portion 13a and the stitching portion 21 is sufficiently maintained, making it easy for the user to grasp that portion with their fingers and to easily insert the button 10 into the buttonhole 5 without stress.

[0057] The distance d1 is preferably 5 mm or more, more preferably 7 mm or more, and even more preferably 10 mm or more. By setting the distance d1 to such a length, the user can easily grasp the space between the first folded portion 13a and the sewn portion 21 with their fingers, so that the button 10 can be easily inserted into the buttonhole 5 without stress.

[0058] Furthermore, the buttonhole 5 is opened in the third fabric 3 such that the distance d3 (see Figure 2) between the end 3a of the third fabric 3 located on the side of the joint 4 with the second fabric 2 and the buttonhole 5 is greater than or equal to the distance d1 (see Figure 4(d)) between the position of the sewing portion 21 which is approximately parallel to the folded portion 13 and the first folded portion 13a. As a result, not only is the distance d1 between the first folded portion 13a and the sewing portion 21 sufficiently maintained at the locking portion 11, but the distance d3 between the end 3a of the third fabric 3 on the joint 4 side and the buttonhole 5 is also sufficiently maintained, making it easier for the user to grasp these parts with their fingers and to insert the button 10 into the buttonhole 5 more easily and with less stress.

[0059] The distance d3 is preferably 5 mm or more, more preferably 7 mm or more, and even more preferably 10 mm or more. By setting the distance d3 to such a length, the user can easily grasp the space between the end 3a of the third fabric 3 on the seam 4 side and the buttonhole 5 with their fingers, so that the button 10 can be easily inserted into the buttonhole 5 without stress.

[0060] With the fabric button 10 described above, and the apron 1 equipped with the button 10, when the locking portion 11 formed on the other end 6b of the first fabric 6 is inserted into the buttonhole 5 opened in the third fabric 3, the locking portion 11 is locked into the buttonhole 5, while the first fabric 6 is connected to the second fabric 2 by a connecting portion 12 formed on one end 6a of the first fabric 6. In this way, the joint 4 between the second fabric 2 and the third fabric 3 of the apron 1 is fastened by the button 10.

[0061] Furthermore, the locking portion 11 is constructed by folding the other end of the first fabric 6 located on the other end 6b side so that the other end 6b of the first fabric 6 is positioned between the first fabric 6s, and sewing the folded first fabric 6 and the first fabric 6 on both sides that sandwich the folded first fabric 6 together with the sewing portion 21.

[0062] In other words, the locking portion 11 is made simply by folding and sewing the first fabric 6, so it can be formed flat. On the other hand, even if the flat locking portion 11 inserted into the buttonhole 5 is pulled in a direction that would cause it to come off, the sewing portion 21 to which the first fabric 6 is sewn will catch and securely lock into the buttonhole 5. As a result, the button 10 is less likely to come off when the seam 4 is fastened. Thus, the button 10 is flat and less likely to come off when the seam 4 is fastened.

[0063] Furthermore, the button 10 according to this embodiment, and the apron 1 equipped with the button 10, provide the effects and advantages described above.

[0064] Although the present invention has been described above based on embodiments, it is easy to infer that the present invention is not limited in any way to the above embodiments, and that various improvements and modifications are possible without departing from the spirit of the present invention. For example, each embodiment may be modified by adding or replacing some or more parts of the configuration of other embodiments with parts or more parts of the configuration of other embodiments, including the modifications described below. Furthermore, the numerical values ​​given in the above embodiments are merely examples, and it is naturally possible to use other numerical values.

[0065] In the above embodiment, the locking portion 11 of the button 10 was described as being formed by folding the other end 6b of the first fabric 6 twice using the second folded portion 13b and the first folded portion 13a, so that it is folded into a "no" shape as shown in Figure 3(a), and then sewing the other end with the sewing portion 21. However, the locking portion 11 only needs to be formed by folding so that the other end 6b of the first fabric 6 is positioned between the first fabric 6, and in that respect, the way it is folded can be arbitrary.

[0066] Here, with reference to Figures 5(a) to 5(c), another example of how to fold the other end of the first fabric 6 on the other end 6b side to form the locking portion 11 will be explained. Figure 5(a) shows an example in which, at the other end of the first fabric 6 on the other end 6b side, a third folded portion 13c is provided as a folded portion 13, in addition to the first folded portion 13a and the second folded portion 13b, and the locking portion 11 is formed by valley folding the first fabric 6 in the order of the third folded portion 13c, the second folded portion 13b, and the first folded portion 13a, so as to fold the first fabric 6 on the front side. Furthermore, Figure 5(b) shows an example in which, compared to Figure 5(a), a fourth folded portion 13d is provided as the folded portion 13, which is the fourth furthest from the other end 6b of the first fabric 6. The locking portion 11 is constructed by valley-folding the first fabric 6 in the order of the fourth folded portion 13d, the third folded portion 13c, the second folded portion 13b, and the first folded portion 13a on the front side. If the first fabric 6 is thin, the locking portion 11 can be given a certain thickness and / or hardness by increasing the number of folds as shown in Figures 5(a) and (b).

[0067] Furthermore, the locking portion 11 does not need to be constructed by valley-folding the first fabric 6 on the front side at all of the multiple folded portions 13. For example, in the example shown in Figure 5(c), the first folded portion 13a to the fourth folded portion 13d are provided as folded portions 13, similar to Figure 5(b), but only the fourth folded portion 13d is folded in a different direction. That is, first, at the fourth folded portion 13d, the first fabric 6 is valley-folded (mountain-folded when viewed from the front) so that it is folded on the back side opposite to the front side, and then the locking portion 11 is constructed by valley-folding the first fabric 6 on the front side in the order of the third folded portion 13c, the second folded portion 13b, and the first folded portion 13a. Thus, it is arbitrary whether each folded portion 13 is valley-folded or mountain-folded when viewed from the front side.

[0068] In the above embodiment, the case in which the first fabric 6 forming the button 10 is made up of a single piece of fabric has been described, but it is not necessarily limited to this. For example, as shown in Figure 5(d), the first fabric 6 may be made up of two pieces of fabric, such as a first front fabric 61 and a first back fabric 62, and the button 10 may be formed on a first fabric 6 made up of multiple pieces of fabric combined. The material of the first front fabric 61 and the material of the first back fabric 62 may be the same or different. Furthermore, these materials may be made up of natural fibers, or chemical fibers may be used in either one or both of them.

[0069] In addition, in the modified examples shown in Figures 5(a) to 5(d), all of the folded first fabric 6 and the first fabric 6 on both sides (outside) that sandwich the folded first fabric 6 are sewn together at least at a sewing portion 21 that is substantially parallel to the folded portion 13. This sewing portion 21 ensures that the locking portion 11 is securely locked into the buttonhole 5, and that the seam 4 can be fastened with the button 10.

[0070] Furthermore, in the modified examples shown in Figures 5(a) to 5(d), the sewing portion 21, which is substantially parallel to the folded portion 13 in the locking portion 11, is preferably set at a position where the distance d1 between the sewing portion 21 and the first folded portion 13a is equal to or longer than the distance d2 between the sewing portion 21 and the second folded portion 13b, as in the above embodiment.

[0071] In the above embodiment, the case in which the locking portion 11 is sewn at a sewing portion 21 that is substantially parallel to the folded portion 13 has been described. However, the locking portion 11 may also be sewn at locations other than the sewing portion 21 (sewing the folded first fabric 6 to the first fabrics 6 on both sides that sandwich the folded first fabric 6).

[0072] Here, with reference to Figures 6(a) and (b), another example of sewing the folded first fabric 6 at the locking portion 11 to the first fabrics 6 on both sides that sandwich the folded first fabric 6 will be explained. Figure 6(a) shows an example in which, in addition to the sewing portion 21, a sewing portion 22 is provided along the first line portion 14a that forms the outer edge of the locking portion 11, connecting one end of the first folded portion 13a and one end of the second folded portion 13b, and the folded first fabric 6 at the locking portion 11 to the first fabrics 6 on both sides that sandwich the folded first fabric 6 is also sewn at this sewing portion 22. In other words, in this example, the locking portion 11 is sewn in a T-shape. In the example of Figure 6(a), even if force is applied to the locking portion 11 from the buttonhole 5, the sewing of the locking portion 11 is made difficult to unravel because it is sewn over a wide area. Therefore, the locking portion 11 can be formed to be robust.

[0073] In the example shown in Figure 6(a), the locking portion 11 is not sewn along the second line portion 14b, which connects the other end of the first folded portion 13a and the other end of the second folded portion 13b that constitute the outer edge of the locking portion 11. If the locking portion 11 were sewn along the second line portion 14b (especially the second line portion 14b on the second folded portion 13b side), it would be difficult to remove the locking portion 11 from the buttonhole 5 because that point would catch on the buttonhole 5. In the example shown in Figure 6(a), the locking portion 11 is not sewn along the second line portion 14b, so when removing the locking portion 11 from the buttonhole 5, it can be easily removed from the vicinity of the unsewn second line portion 14b.

[0074] Figure 6(b) shows an example in which, in addition to the stitching portion 21, a stitching portion 23 is provided along the first line portion 14a on the side of the stitching portion 21 to the first folded portion 13a, and a stitching portion 24 is provided along the second line portion 14b on the side of the stitching portion 21 to the first folded portion 13a, and in these stitching portions 23 and 24 as well, the folded first fabric 6 in the locking portion 11 and the first fabric 6 on both sides that sandwich the folded first fabric 6 are sewn together. In other words, in this case, the locking portion 11 is sewn in a U-shape. Even in the example of Figure 6(b), even if force is applied to the locking portion 11 from the buttonhole 5, the stitching of the locking portion 11 is sewn over a wide area, making it difficult for the stitching of the locking portion 11 to come undone. Therefore, the locking portion 11 can be made strong. Furthermore, since stitching is not performed along the second line portion 14b on the side of the second folded portion 13b from the stitching portion 21, when removing the locking portion 11 from the buttonhole 5, the locking portion 11 can be easily removed from the vicinity of the unstitched second line portion 14b.

[0075] In the above embodiment, the seam 4 fastened by the button 10 was made of two separate pieces of fabric 2 and three pieces of fabric 3. However, the seam 4 fastened by the button 10 may be a seam made of a single piece of fabric (for example, a seam created by rolling up a single piece of fabric). In this case, the second piece of fabric of the present invention refers to the portion of that single piece of fabric to which the button 10 is attached, and the third piece of fabric of the present invention refers to the portion of that single piece of fabric to which the buttonhole 5 is formed. In other words, the second piece of fabric and the third piece of fabric may refer to the same piece of fabric.

[0076] In the above embodiment, the case in which the button 10 is provided on the apron 1 was described, but the button 10 may be provided not only on the apron 1 but also on any garment. Furthermore, the button 10 may be used not only on garments but also for the purpose of fastening the seam between two pieces of fabric. [Explanation of Symbols]
