Snap Button with Variable Attachment Position

Abstract

[Problem] When a fastener is attached to a fabric of a garment and the like, the fastener may be fixed by sewing or punching; however, this leads to the problem that the fastener cannot be connected when the fastening position is shifted due to a change in body shape, making the garment unwearable. [Solution] The present invention provides a snap button with variable fastening positions that is not fixed to a fabric by punching or the like, and yet can connect two fabrics even when the fastening position is changed. A snap button 1 with variable fastening positions according to the present invention comprises: a female button 2; an intermediate button 3 to be elastically engaged with the female button 2; and a male button 4 to be elastically engaged with the intermediate button 3. The female button 2 is disposed in a predetermined position on a first face of a first fabric C1. The intermediate button 3 is disposed in a position on a second face of the fabric corresponding to the predetermined position. The female button 2 and the intermediate button 3 are elastically engaged together via the fabric to fasten the fabric, and then the buttons are fixed. Next, the male button 4 and the intermediate button 3 are elastically engaged together via a second fabric C2 to fasten the fabric, and then the buttons are fixed, whereby the first and second fabrics C1, C2 are connected.

Description

Technical Field

[0001] The present invention relates to a fastener for connecting two planar materials such as the fabric of clothes, and particularly to a snap button with variable fastening position that can connect the materials without sewing or drilling holes in the fabric and can freely change the fastening position.

Background Art

[0002] Conventionally, as fasteners for connecting two planar materials such as the fabric of clothes, there are so-called button-and-buttonhole pairs, fastener pairs, hook-and-loop fastener pairs, snap button pairs, etc. However, all of these conventional fastener pairs are firmly fixed at predetermined positions on the fabric by sewing, heat welding, drilling, etc., and the fastening position of the button pair cannot be freely changed. For example, in a shirt, buttons are fixed to the fabric by sewing corresponding to buttonholes, and even if the fastening position of the pair changes due to changes in body shape, etc., the fastening position of the buttons cannot be changed accordingly. That is, the two pieces of fabric cannot be connected, the fastener does not function, and the clothes cannot be properly worn on the body. The same applies to hook-and-loop fastener pairs and snap button pairs.

[0003] In daily life, the body shape often changes due to body growth, obesity, pregnancy, before and after meals, etc., and the fastening positions of the fastener pairs of the two pieces of fabric do not match, resulting in the clothes becoming unwearable. Body shapes vary from person to person in terms of height, sitting height, torso, waist circumference, etc., and also change briefly for each individual, such as the torso circumference size before and after meals. Although individuals can make efforts such as changing buttons, it is time-consuming and not a solution that is effective for everyone. That is, although there is a need for fasteners on clothes to adapt to changes in body shape as described above, no effective, simple, and practical proposal has been made to solve this need with conventional fasteners.

Patent Document 2

[0005] Patent Document 1 discloses a state-of-the-art snap button that can also be attached to thick fabrics. However, like conventional snap buttons, the snap button of Patent Document 1 also requires drilling holes in the fabric for attachment, so the fastening position is fixed and cannot be changed according to changes in body shape. Patent Document 2 discloses a suspender for pants that includes an internal clip 10 having an elastic ring portion 14 and an external clip 20 having a locking groove 26 that engages with the elastic ring portion 14 and a support means 27 for the pants T. The internal clip 10 and the external clip 20 are elastically engaged with each other with the upper garment S sandwiched between the elastic ring portion 14 and the locking groove 26. Since the external clip 20 is fixed to the pants T by the support means 27, the upper garment S and the pants T can be connected to prevent the pants T from falling. Here, the internal clip 10 is in a free state when not engaged with the external clip 20. As the internal clip 10 is provided with a ring 18 (Fig. 1) for fastening the shoulder strap, every time when connecting the pants and the upper garment, it is necessary to secure several free internal clips 10 and elastically engage them with the paired external clips 20 respectively with the upper garment S sandwiched therebetween, which is more troublesome and inconvenient than conventional suspenders and not practical. Patent Document 3 discloses an internal suspender that holds pants by a plurality of members provided with fastener elements. The internal suspender sandwiches the outer garment between members 28 and 34 each provided with a fastener element, and further holds the pants by engaging with the fastener element inside the pants. Here, each fastener element and member are arranged and fixed on the belt line desired by the user on the inner wear, outer garment, and inside of the pants. However, even on the belt line, there are individual differences in body shape as described above, and the body shape also changes daily individually. If those members are fixed at a certain position, they cannot cope with changes in body shape. [Summary of the Invention] [Problems to be Solved by the Invention]

[0006] When fastening two pieces of fabric of clothing or the like, conventional fasteners perform hole drilling or the like to firmly fix the fastening position. However, if the body shape changes and the fastening position changes, the fabric cannot be fastened, and there is a problem that the clothing becomes unwearable. In view of such problems, the present invention has been made. It provides a simple and practical snap button with a variable fastening position that can fix the fabric without performing hole drilling or the like, and can move the fastening position of the fastener according to changes in body shape to connect two pieces of fabric.

The elongated male button is obtained by elongating the aforementioned male button in the longitudinal direction. Similar to the male button, it includes an engaging protrusion that elastically engages with the bending engaging portion of the intermediate button, a bending portion bendable in the longitudinal direction, and a flange. The reverse female button is obtained by turning the aforementioned female button upside down, and includes a peripheral engagement / disengagement claw whose outer periphery is radially divided into a plurality of parts, and a pressing portion with a curved cross-section. The female button is arranged at a predetermined position on the first surface side of the first fabric, the intermediate button is arranged at a position on the second surface side of the first fabric corresponding to the predetermined position of the female button, and by pressing the intermediate button against the female button through the first fabric, the female button and the intermediate button are elastically engaged to fasten the first fabric at the predetermined position and at the same time fix the female button and the intermediate button. Next, the elongated male button is arranged at a position on the first surface side of the second fabric corresponding to the predetermined position, and by pressing the elongated male button against the reverse female button through the second fabric, the reverse female button and the elongated male button are elastically engaged to fasten the second fabric and at the same time fix the reverse female button and the elongated male button. Then, by pressing the elongated male button against the intermediate button to snap-fit, the first and second fabrics are connected.

[0009] According to still another aspect of the present invention, the snap button with variable fastening position of the present invention comprises a female button, an intermediate button, and a U-shaped clip. The female button includes a peripheral engagement / disengagement claw whose outer periphery is radially divided into a plurality of parts, and a pressing portion with a curved cross-section. The intermediate button includes an engaging portion that elastically engages with the female button through a third fabric, and a bending engaging portion provided with a plurality of slits on the outer periphery and bendable in the radial and longitudinal directions. The U-shaped clip integrally includes a male button portion that snap-fits with the intermediate button on the outer surface of the first surface side, has a plurality of tooth surfaces that are offset from each other on the inner surface, and is formed so that elasticity acts in the closing direction. Place the female button at a predetermined position on the first surface side of the third fabric, press the intermediate button against the female button through the third fabric, and elastically engage the female button and the intermediate button at the predetermined position to fasten the third fabric. At the same time, fix the female button and the intermediate button. Near the fixing position, fasten the fourth fabric with a U-shaped clip, and press the male button part against the intermediate button to elastically engage the intermediate button and the male button part, and snap-fit the intermediate button and the U-shaped clip to connect the third and fourth fabrics.

[0010] According to still another aspect of the present invention, the snap button with variable fastening position of the present invention integrally includes an intermediate button portion on the outer surface of the second surface side, and an elastic engagement portion having a plurality of tooth surfaces that are offset from each other on the inner surface, and a first U-shaped clip formed so that elasticity acts in the closing direction, and a male button portion that snap-fits with the intermediate button portion is integrally provided on the outer surface of the first surface side, and an elastic engagement portion having a plurality of tooth surfaces that are offset from each other on the inner surface, and a second U-shaped clip formed so that elasticity acts in the closing direction, Fasten the fifth fabric with the first U-shaped clip and fasten the sixth fabric with the second U-shaped clip, Connect the first and second U-shaped clips by snap-fitting the male button portion and the intermediate button portion, and connect the fifth and sixth fabrics.

Advantages of the Invention

[0011] According to the snap button with variable fastening position of the present invention, by elastically engaging the intermediate button with the female button through the first fabric, the first fabric can be fastened and at the same time the female button and the intermediate button can be fixed. Further, by elastically engaging the male button with the fixed intermediate button through the second fabric, the second fabric can be fastened and at the same time the intermediate button and the male button can be fixed. Therefore, the female button and the intermediate button can be fixed to the first fabric without perforating the fabric, etc., and the intermediate button and the male button can be fixed to the second fabric. Thus, by elastically engaging the female button, the intermediate button, and the male button, the first fabric and the second fabric can be connected.

[0012] Here, the engaging positions of the female button, the intermediate button, and the male button can be anywhere with the first and second fabrics interposed therebetween. That is, according to the change in body shape, the fastening positions of the female button, the intermediate button, and the male button can be changed and fixed. The fastening positions of the female button, the intermediate button, and the male button can be repositioned to the optimal position according to the change in body shape any number of times. Once arranged at the optimal position, each button will not become loose and the connection between the first and second fabrics will not be released unless the engagement is intentionally released.

[0013] According to the fastening position variable snap button of another aspect of the present invention, the basic operation is the same as that of the fastening position variable snap button of the aforementioned aspect. The female button and the intermediate button are elastically engaged and fixed via the first fabric, and the elongated male button and the reverse female button are elastically engaged and fixed via the second fabric. Therefore, before connecting the first and second fabrics, each button is fixed to the first and second fabrics, and finally the intermediate button and the elongated male button are snap-fitted to connect the first and second fabrics like a normal snap button. Needless to say, even if fixed once in this embodiment, the elastic engagement of each button can be released and the fastening position can be freely changed.

[0014] According to the fastening position variable snap button of still another aspect of the present invention, it is possible to cope even when the thickness and hardness of the fabrics are different from each other. That is, the female button part and the intermediate button are elastically engaged and fixed via the third fabric, the fourth fabric is fastened with a U-shaped clip provided with a male button part to determine the position of the male button part, and the male button part of the U-shaped clip fixed to the fourth fabric is pressed against the intermediate button and fitted to connect the third and fourth fabrics. Further effects and advantages of the fastening position variable snap button of the present invention will become apparent from the detailed description with reference to the following drawings.

Embodiments for Carrying Out the Invention

[0016] Embodiments of the variable fastening position snap button of the present invention will be described below together with respective examples. (Example 1) Figs. 1A to 1D are exploded enlarged sectional views of the variable fastening position snap button 1 of Example 1. Fig. 1A shows the female button 2 of the variable fastening position snap button 1, Fig. 1B shows the intermediate button 3, Fig. 1C shows the male button 4 respectively, and Fig. 1D is an enlarged sectional view in which each part of the variable fastening position snap button 1 is pressed and elastically engaged through the first and second fabrics C1, C2 for assembly. Further, Fig. 2 is an exploded enlarged perspective view of the variable fastening position snap button 1. Fig. 2A shows the female button 2, Fig. 2B shows the intermediate button 3, and Fig. 2C shows the male button 4 respectively. Specifically, the female button 2 in Fig. 1A is composed of a pressing portion 21 having a curved cross section and a peripheral engaging and disengaging claw 22 divided by a plurality of slits arranged on the periphery of the pressing portion 21. The intermediate button 3 in Fig. 1B includes an engaging portion 31 that elastically engages with the peripheral engaging and disengaging claw 22 of the female button 2 through the first fabric C1, and a plurality of slits 33 on the outer periphery to make the intermediate button 3 bendable in the radial direction and the longitudinal direction and an elastic engaging portion 32 that elastically engages with the engaging protrusion 41 of the male button 4. The male button 4 in Fig. 1C is composed of an engaging protrusion 41 that elastically engages with the bending engaging portion 32 of the intermediate button 3 through the second fabric C2, a bending portion 42 that makes the male button 4 expandable and contractible in the longitudinal direction, and a flange 43 around the bending portion 42.

[0017] Here, as shown in FIGS. 1A and 1B, the female button 2 is disposed at a predetermined position on the first surface D1 side of the first fabric C1 according to the body shape, the intermediate button 3 is disposed at a position on the second surface D2 side of the first fabric C1 corresponding to the predetermined position of the female button 2, and the intermediate button 3 is pressed in the F1 direction against the female button 2 through the first fabric C1. Thereby, the peripheral engagement / disengagement claws 22 of the female button 2 expand, elastically engage with the engaging portion 31 of the intermediate button 3 through the first fabric C1, and the female button 2 and the intermediate button 3 fasten and fix the first fabric C1 at a predetermined position and are no longer free from each other. Next, as shown in FIG. 1C, when the male button 4 is pressed in the F2 direction against the intermediate button 3 at the fixed predetermined position through the second fabric C2, the bent engaging portion 32 of the intermediate button 3 expands and elastically engages with the engaging protrusion 41 of the male button 4. That is, the intermediate button 3 and the male button 4 also fasten and fix the second fabric C2 at a predetermined position and are no longer free from each other, whereby the first and second fabrics C1 and C2 can be connected as shown in the overall assembled view of FIG. 1D.

[0018] Here, the peripheral engagement / disengagement claws 22 divided by the plurality of slits of the female button 2 have elasticity and flexibility. When pressed against the engaging portion 31 of the intermediate button 3, the peripheral engagement / disengagement claws 22 bend in the D1 direction with the boundary between the peripheral engagement / disengagement claws 22 and the pressing portion 21 as a fulcrum and expand in a form that narrows the slit interval, and the female button 2 and the intermediate button 3 elastically engage through the first fabric C1. The intermediate button 3 also has elasticity and flexibility due to the bent engaging portion 32 formed in a U-shaped cross-section and the plurality of slits 33. When the engaging protrusion 41 of the male button 4 is press-fitted into the bent engaging portion 32, the bent engaging portion 32 expands in a form that narrows the gap between the slits 33, and the intermediate button 3 and the male button 4 elastically engage through the second fabric C2. The male button 4 also has elasticity and flexibility due to the bent portion 42 having a U-shaped cross-section. The bent engaging portion 32 of the intermediate button 3 is inserted into the female button 2 through the first fabric C1. However, since the bent engaging portion 32 is provided with a plurality of slits 33 and also has a slight space from the tip of the peripheral engagement / disengagement claws 22 of the female button 2, it easily expands when the engaging protrusion 41 of the male button 4 is press-fitted, and the intermediate button 3 and the male button 4 elastically engage. That is, the female button 2, the intermediate button 3, and the male button 4 are structurally snap-fitted, but have elasticity and flexibility, so they elastically engage even through the fabric.

[0019] Here, the thicknesses of the first and second fabrics C1 and C2 are about 0.5 mm, and the vertical elasticity and flexural stroke of the intermediate button 3 and the male button 4 are also about 0.5 mm. By adjusting the elasticity and flexural property, it is possible to accommodate fabrics of different thicknesses. That is, by loosening the elasticity and flexural property of each snap button to reduce the fastening force on the fabric, a thicker fabric can be fastened. Alternatively, the fastening force of each snap button can be increased, or the surface can be textured to increase the frictional resistance between each fabric and each snap button, so that they can be fixed more firmly. When the fabric is very thick or hard, it will be described later in Example 3.

[0020] When the variable fastening position snap button 1 is not fastened through the fabric, the female button 2, the intermediate button 3, and the male button 4 can be snap-fitted together and held in an integrated state. In short, by fastening the first and second fabrics C1 and C2 at a predetermined position with the elastic and flexible female button 2, intermediate button 3, and the intermediate button 3 and male button 4, each button is fixed, and each fabric is also fixed and connected. The material of the variable fastening position snap button of the present invention is made of a hard plastic or metal having elasticity.

[0021] When the pressing portion 21 of the female button 2 is pressed, based on the lever principle with the boundary between the pressing portion 21 and the peripheral engaging / disengaging claw 22 as the fulcrum, the peripheral engaging / disengaging claw 22 moves in a direction away from and rising from the first fabric C1, and the elastic engagement between the peripheral engaging / disengaging claw 22 and the intermediate button 3 through the first fabric C1 can be released. That is, by simply pressing the pressing portion 21 of the female button 2, the elastic engagement with the intermediate button 3 can be released, and the fastening position can be changed as many times as needed until the optimal fastening position is reached according to the body shape change. Furthermore, here, while lightly pressing the pressing portion 21 to hold the facing positions of the female button 2 and the intermediate button 3 with both fingers to release the elastic engagement between the two buttons, the female button 2 and the intermediate button 3 are slid with the first fabric C1 sandwiched therebetween, and the two buttons are elastically engaged at the optimal position, so that the first fabric C1 can be fastened and the two buttons can be fixed. That is, the fastening position can be easily and freely changed.

[0022] Incidentally, Japanese Patent Application Laid-Open No. 2021-154120 of Patent Document 1 discloses a snap button of the latest technology that can be attached to thick fabrics. However, like conventional snap buttons, when attaching, hole punching is required on the fabric, so the fastening position is fixed, and the fastening positions of the button pair cannot be changed. That is, there is a common perception that conventional snap buttons are those that are firmly fixed by punching holes in the fabric. However, the snap button with variable fastening position of the present invention can be fixed without punching holes in the fabric, and the fastening positions of the button pair can also be freely changed, which is decisively different from conventional snap buttons.

[0023] Incidentally, the elastic engagement between the female button 2 and the intermediate button 3 is mechanical in structure and is not released except by intentionally pressing the pressing portion 21 of the female button 2, and does not become loose even during washing or the like. That is, while the fastening positions of the female button 2 and the intermediate button 3 on the first fabric C1 can be fixed semi-permanently, by pressing the pressing portion 21 of the female button 2 as needed, the elastic engagement between the female button 2 and the intermediate button 3 can be released, and the fastening position can be changed.

[0024] Also, when elastically coupling the female button 2 and the intermediate button 3 via the first fabric C1, wrinkles may form in the first fabric C1 around the female button 2. However, as in the specific example described later, the female button 2 is in a position where it cannot be seen from the outside and does not pose a visual problem. Also, depending on the fabric, the elastic engagement marks may not remain, or can be almost completely erased by ironing. When elastically engaging the intermediate button 3 and the male button 4, wrinkles may form around the fastening position of the second fabric C2. However, by increasing the diameter of the flange 43 and providing a slight gap between the second fabric C2 and the flange 43, the wrinkles of the second fabric C2 can be hidden. Furthermore, by inserting a finger into this gap and pulling the flange 43 in a direction away from the second fabric C2, the elastic engagement with the intermediate button 3 can be released.

[0025] The following describes a specific example of applying the above-described snap button 1 with variable fastening positions to an undergarment shirt and pants. Conventionally, pants are worn by tightening them around the body with an elastic material such as a rubber band. However, when the body shape changes due to obesity, after eating, pregnancy, etc., and the waist circumference increases, the rubber band becomes tight and causes discomfort, inhibits breathing and blood circulation, leaves rubber marks on the body, and causes the body to be chafed by the rubber band. Also, when the waist circumference decreases, the pants tend to slip off. Therefore, it is desirable for pants to be wearable on the body regardless of the waist circumference size without the need for a rubber band or the like.

[0026] Therefore, as shown in FIGS. 3 and 4, specifically, it is proposed to replace the first fabric C1 with the shirt S and the second fabric C2 with the pants P, and connect the shirt S and the pants P vertically like a piece of clothing using the snap button 1 with variable fastening positions of Example 1. FIG. 3 is a perspective view when the shirt S and the pants P are fastened with the snap button 1 with variable fastening positions and worn on the body B. As shown in FIG. 3, if the shirt S and the pants P can be worn on the body B by fastening at least three locations, namely, two locations near the front lumbar vertebra and one location near the spine, centered on the body B. FIG. 4 is an enlarged longitudinal sectional view of one of the snap buttons 1 with variable fastening positions, showing the overall assembly view of the snap button 1 in FIG. 1D with the first and second fabrics C1 and C2 replaced by the shirt S and the pants P and shown vertically centered on the body B.

[0027] The female button 2 is arranged at a predetermined position on the first surface D1 side of the shirt S, and the intermediate button 3 is arranged on the second surface D2 side of the shirt S at a position corresponding to the predetermined position of the female button 2. When the intermediate button 3 is pressed against the female button 2 through the shirt S, the female button 2 elastically engages with the intermediate button 3. Due to this elastic engagement, the shirt S is fastened by the female button 2 and the intermediate button 3, and the female button 2 and the intermediate button 3 are fixed at the predetermined positions and do not become disengaged. Next, when the male button 4 is pressed against the intermediate button 3 at the predetermined position through the pants P, the intermediate button 3 elastically engages with the male button 4. As a result, the pants P are fastened by the intermediate button 3 and the male button 4, and the shirt S and the pants P can be connected. Incidentally, by reversing this series of engagement orders, first elastically engaging the intermediate button 3 with the male button 4 through the pants P, and then elastically engaging the female button 2 with the intermediate button 3 through the shirt S, it is also possible to connect the shirt S and the pants P.

[0028] Here, as described above, by pressing the pressing portion 21 of the female button 2, the peripheral engaging / disengaging claw 22 moves in a direction away from the shirt S, and the elastic engagement with the intermediate button 3 through the shirt S can be released. Then, holding the facing relationship between the female button 2 and the intermediate button 3 with both fingers, pressing the pressing portion 21 to make the female button 2 and the intermediate button 3 in a non-engaged state, and sliding the female button 2 and the intermediate button 3 with the shirt S sandwiched therebetween, at the optimal fastening position according to the change in body shape at that time, the intermediate button 3 can be pressed against the female button 2 or the pressing of the pressing portion 21 can be stopped to achieve elastic engagement. Until then, the elastic engagement position, that is, the fastening position, can be changed as many times as desired. The elastic engagement between the female button 2 and the intermediate button 3 is strong and is not released except by intentionally pressing the pressing portion 21 of the female button 2, and it does not become disengaged even after washing. That is, while the fastening position of the female button 2 and the intermediate button 3 on the shirt S can be fixed semi-permanently, the elastic engagement between the female button 2 and the intermediate button 3 can be easily released as needed due to changes in body shape, etc., and the fastening position can be changed.

[0029] As described above, since the fastening position variable snap button 1 can securely fasten the shirt S and the pants P vertically like a piece of clothing, even if the body shape changes and the body circumference increases or decreases, the optimal fastening position of the pants P can be selected according to the body shape and connected to the shirt, and the pants P can be worn without a rubber band. That is, it is no longer necessary to fasten the pants P to the body B with a rubber band or the like. There is no rubber mark on the skin, and it is healthy both respiratorily and circulatorily, and it will not slip off.

[0030] It is possible to fasten the shirt and the pants like a piece of clothing by attaching conventional snap buttons or hook-and-loop fasteners to the shirt and the pants respectively. However, there are individual differences in human body shapes, with different heights (sitting heights) and body circumference sizes, and even for an individual, the body circumference size differs between before and after a meal in a day. That is, just as commercially available dress shirts are available in a very wide range of sizes according to the body circumference and neck circumference, etc., if the fastening positions of an unspecified number of upper and lower garments are uniformly fixed with snap buttons or hook-and-loop fasteners, for people with different body shapes or those whose body shapes are likely to change, such as those with a fat body shape, the fastening positions of the upper and lower garments will not match and they will be unable to wear them. That is, it was almost impossible to sell upper and lower connected garments with fixed fastening positions to an unspecified large number of people with individual differences in body shape. However, with the fastening position variable snap button of the present invention that can change the fastening position according to the body shape, even if the body shapes are somewhat different or for those whose body shapes are likely to change, commercially available clothing can be worn on the body like upper and lower connected garments. In addition, when the body circumference size decreases or when only the pants without a rubber band are worn without wearing a shirt, the number of the fastening position variable snap buttons of the present invention can be increased to, for example, 4, and the length between each snap button can be adjusted to be shorter, and the overall body circumference size can be reduced so that it can be worn on the body.

[0031] In the above-described Example 1, specific examples applied to the shirt S and the pants P were shown. However, the application examples of the snap button 1 with variable fastening position of the present invention are not limited to those. That is, there are many planar materials that require no drilling or other processing and can be non-destructively changed in fastening position, other than shirts and pants. For example, hemming of kimonos and yukatas, simple culotte conversion of skirts, bed making of sheets, fixing of gauze, connection of paper, films, and net-like materials, etc. The snap button 1 with variable fastening position of the present invention can be used for those connections.

[0032] (Example 2) Example 2 of the snap button with variable fastening position of the present invention will be described with reference to FIG. 5. The snap button 101 with variable fastening position in Example 2 is structurally and functionally similar to the snap button 1 with variable fastening position in Example 1, except for a part. Therefore, the corresponding components are denoted by the same or corresponding reference numerals, and their detailed descriptions are appropriately omitted. FIGS. 5A to 5E are exploded enlarged cross-sectional views of the snap button 101 with variable fastening position in Example 2. FIG. 5A shows the female button 2 of the snap button 101 with variable fastening position, FIG. 5B shows the intermediate button 3 that elastically engages with the female button 2 through the first fabric C1, FIG. 5C shows the elongated male button 4' obtained by lengthening the male button 4 shown in FIG. 1C in the vertical direction, FIG. 5D shows the female button 2 of FIG. 5A turned upside down, and the inverted female button 2' that elastically engages with the elongated male button 4' through the second fabric C2, respectively. FIG. 5E is an enlarged cross-sectional view when each part of the snap button 101 with variable fastening position is pressed and elastically engaged through the first and second fabrics C1 and C2 for assembly.

[0033] Specifically, similar to Example 1, the female button 2 in Fig. 5A consists of a pressing portion 21 with a curved cross-section and a peripheral engagement / disengagement claw 22 arranged at the periphery of the pressing portion 21. The intermediate button 3 in Fig. 5B includes an engaging portion 31 that elastically engages with the female button 2 via the first fabric C1, and a bending engaging portion 32 that is provided with a plurality of slits 33 on the outer periphery to enable the intermediate button 3 to be bent in the radial and longitudinal directions and elastically engages with the engaging protrusion 41 of the elongated male button 4'. The elongated male button 4' in Fig. 5C includes an engaging protrusion 41, a bending portion 42, and a flange 43. Note that the elongated male button 4' is obtained by increasing only the thickness of the male button 4 in Example 1, and its other structures and functions are the same as those of the male button 4. The reverse female button 2' in Fig. 5D consists of a pressing portion 21 with a curved cross-section and a peripheral engagement / disengagement claw 22 that elastically engages with the elongated male button 4' via the second fabric C2.

[0034] As shown in Figs. 5A and 5B here, the female button 2 is arranged at a predetermined position corresponding to the shape on the first surface D1 side of the first fabric C1, and the intermediate button 3 is arranged on the second surface D2 side of the first fabric C1 at a position corresponding to the predetermined position of the female button 2. Then, by pressing the intermediate button 3 against the female button 2 in the F1 direction via the first fabric C1, the female button 2 and the intermediate button 3 elastically engage to fasten the first fabric C1, and both buttons are fixed at the predetermined position and do not become free. Next, as shown in Figs. 5C and 5D, the elongated male button 4' is arranged near a predetermined position on the first surface D1 side of the second fabric C2, and by pressing the elongated male button 4' against the reverse female button 2' in the F2 direction via the second fabric C2, the reverse female button 2' and the elongated male button 4' elastically engage to fasten the second fabric C2, and both buttons are fixed near the predetermined position. Then, by pressing the reverse female button 2' and the elongated male button 4' against the intermediate button 3 fixed at the predetermined position in the F3 direction, the intermediate button 3 and the elongated male button 4' snap-fit, and the first and second fabrics C1 and C2 can be connected. Note that in this case, when pressing the pressing portion 21 of the reverse female button 2', there is a risk of releasing the elastic engagement with the elongated male button 4'. However, since the pressing direction is unidirectional, even if the elastic engagement is temporarily released, as long as the intermediate button 3 and the elongated male button 4' snap-fit, the reverse female button 2' and the elongated male button 4' will immediately elastically engage again.

[0035] That is, the position-adjustable snap button 1 of Example 1 elastically engages and fixes the female button 2 and the intermediate button 3 via the first fabric C1, and then elastically engages the intermediate button 3 and the male button 4 via the second fabric C2 to connect the first and second fabrics C1 and C2. In contrast, the position-adjustable snap button 102 of Example 2 elastically engages and fixes the female button 2 and the intermediate button 3 via the first fabric C1, and then elastically engages and fixes the elongated male button 4' and the reverse female button 2' via the second fabric C2. Then, the intermediate button 3 and the elongated male button 4' are snap-fitted to connect the first and second fabrics C1 and C2, which is different.

[0036] That is, by disengaging the snap fit between the intermediate button 3 and the elongated male button 4', the connection between the first and second fabrics C1 and C2 can be disengaged. Note that, similar to Example 1, by pressing the pressing portion 21 of the female button 2 or the reverse female button 2', the elastic engagement between the female button 2 and the intermediate button 3 or the reverse female button 2' and the elongated male button 4' through the fabric can be released. That is, while holding the facing relationship between the female button 2 and the intermediate button 3 or the reverse female button 2' and the elongated male button 4' through the first and second fabrics C1 and C2 with both fingers, press the pressing portion 21 to be in a disengaged state, and slide each button while sandwiching the first and second fabrics C1 and C2. Then, elastically engage at the optimal fastening position according to the body shape change at that time to fasten the fabric and fix each button. That is, the elastic engagement position, that is, the fastening position, can be freely changed.

[0037] Hereinafter, in this example as well, specifically, the first and second fabrics C1 and C2 are replaced with an undershirt S and pants P, and an example of applying the above-described position-adjustable snap button 101 will be described. Note that, in this Example 2 as well, the arrangement of the position-adjustable snap button 101 around the body is the same as in FIGS. 3 and 4, so it is not shown.

[0038] Unlike Example 1, in this Example 2, the female button 2 and the intermediate button 3 are elastically engaged and fixed via the shirt S, and the reverse female button 2' and the elongated male button 4' are elastically engaged and fixed via the pants P. The fixed intermediate button 3 and the elongated male button 4' are snap-fitted to connect the shirt S and the pants P. Other basic operations are the same as those in Example 1.

[0039] That is, the female button 2 is arranged at a predetermined position corresponding to the body shape on the first surface D1 side of the shirt S, and the intermediate button 3 is arranged at a position on the second surface D2 side of the shirt S corresponding to the predetermined position of the female button 2. Then, when the intermediate button 3 is pressed in the F1 direction against the female button 2 via the shirt S and the female button 2 and the intermediate button 3 are elastically engaged, the shirt S is fastened, and both buttons are fixed at the predetermined position and do not become free. Next, the reverse female button 2' is arranged near a predetermined position on the second surface D2 side of the pants P, and the elongated male button 4' is arranged at a position on the first surface D1 side of the pants P corresponding to the vicinity of the predetermined position of the reverse female button 2'. When the elongated male button 4' is pressed in the F2 direction against the reverse female button 2' via the pants P, the reverse female button 2' and the elongated male button 4' are elastically engaged to fasten the pants P, and both buttons are fixed near the predetermined position and do not become free. Then, by pressing the elongated male button 4' in the F3 direction against the intermediate button 3, the intermediate button 3 and the elongated male button 4' are snap-fitted, and the shirt S and the pants P can be connected like a normal snap button. Also, if the snap fit between the intermediate button 3 and the elongated male button 4' is released, the shirt S and the pants P can be separated.

[0040] Here, similar to Example 1, by simply pressing the pressing portion 21 of the female button 2 or the reverse female button 2', the elastic engagement between the female button 2 and the intermediate button 3 or the reverse female button 2' and the elongated male button 4' via the shirt S or the pants P at the predetermined position can be released. That is, the female button 2 and the intermediate button 3 or the reverse female button 2' and the elongated male button 4' are held with both fingers in their facing relationship and slid while sandwiching the shirt S or the pants P in the disengaged state, and elastic engagement can be achieved at the optimal fastening position that matches the change in body shape at that time. That is, the position can be easily changed any number of times, and the fastening position can be changed.

[0041] As described above, in the second embodiment as well, since the detachable position variable snap button 101 can surely fasten the shirt S and the pants P vertically like a piece of clothing, even if the body shape changes and the girth increases or decreases, the optimal fastening position of the pants P can be selected according to the body shape, and the pants P can be connected to the shirt S without an elastic cord and worn. That is, it is not necessary to tighten the body B with an elastic cord or the like for wearing, the elastic mark does not stick to the skin, breathing is easy, blood circulation is good, and the pants P do not slip off even if the girth decreases. That is, if the tightening of the elastic stretchable body of the conventional pants is too tight, even if the elastic stretchable body is removed or cut, the shirt and the pants can be connected by the detachable position variable snap button 101 of the present invention and worn on the body, and the pants without an elastic stretchable body can also be worn on the body.

[0042] Furthermore, similar to the first embodiment, in this embodiment as well, the elastic engagement between the female button 2, the intermediate button 3, the reverse female button 2', and the elongated male button 4' is structurally strong and is not released unless the pressing portion is intentionally pressed, and it does not become detached even when washed. That is, while the fastening positions of the female button 2, the intermediate button 3, the reverse female button 2', and the elongated male button 4' on the shirt S and the pants P can be fixed semi-permanently, if necessary, the elastic engagement between the female button 2 and the intermediate button 3 or the reverse female button 2' and the elongated male button 4' can be released, and while maintaining their facing relationship, the shirt S and the pants P can be sandwiched and slid to re-engage elastically, then the fastening position can be easily and freely changed.

[0043] Although the application examples to the shirt S and the pants P were shown in the above-described second embodiment, the application examples of the detachable position variable snap button 101 of the present invention are not limited to those. That is, a fastener with a variable fastening position can be fixed non-destructively to each of two planar materials such as two pieces of fabric without drilling or sewing, and connecting the two planar materials by snap-fitting the fixed fasteners is not limited to clothing such as underwear. For example, there are hem stops for kimonos and yukatas, simple culotte conversion of skirts, gauze stops, bed making of sheets, connection of paper, films, and net-like materials, etc., and the detachable position variable snap button 101 of the present invention can also be used when connecting them to each other.

[0044] (Example 3) In Examples 1 and 2, the snap buttons 1 and 101 with variable fastening positions of the present invention were applied to the shirt S and the pants P. However, in conventional pants, there may be cases where the female button 2 and the intermediate button 3 cannot be elastically engaged through the pants because there is a rubber elastic body or thickness at the fastening position. Therefore, the snap button 201 with a variable fastening position of the present embodiment is capable of coping with cases where the fabric is thick, hard, or has a rubber elastic body, and otherwise is substantially the same as the snap button 1 with a variable fastening position of Example 1 in terms of structure and operation. Therefore, corresponding components are indicated by the same or corresponding reference numerals, and their detailed descriptions are omitted as appropriate.

[0045] The snap button 201 with a variable fastening position according to Example 3 of the present invention will be described with reference to FIG. 6. FIGS. 6A to 6D are exploded enlarged cross-sectional views of the snap button 201 with a variable fastening position according to Example 3. FIG. 6A shows the female button 2 of the snap button 201 with a variable fastening position, FIG. 6B shows the intermediate button 3 that elastically engages with the female button 2 through the third fabric C3, and FIG. 6C shows a U-shaped clip 5 integrally provided with a male button portion 51 that elastically engages with the bending engagement portion 32 of the intermediate button 3 on the outer surface and having a plurality of tooth surfaces 52 for fastening a thick or hard fourth fabric C4. Note that the basic shape and operation of the male button portion 51 of the U-shaped clip 5 are the same as those of the male button 4 of Examples 1 and 2. FIG. 6E is an enlarged cross-sectional view of assembling each part of the snap button 201 with a variable fastening position by pressing through the third and fourth fabrics C3 and C4 and elastically engaging.

[0046] Specifically, the female button 2 in FIG. 6A, like in Examples 1 and 2, consists of a pressing portion 21 with a curved cross-section and a peripheral engagement / disengagement claw 22 arranged at the periphery of the pressing portion 21. The intermediate button 3 in FIG. 6B includes an engagement portion 31 that elastically engages with the female button 2 through the first fabric 3, and a plurality of slits 33 on the outer periphery to make the intermediate button 3 bendable in the radial and longitudinal directions, and a bending engagement portion 32 that elastically engages with the male button portion 51 of the U-shaped clip 5. The U-shaped clip 5 in FIG. 6C integrally forms the male button portion 51 on the outer surface on the D1 side, has a plurality of tooth surfaces 52 on both inner surfaces, and is formed to be biased in the inward closing direction.

[0047] Here, similar to Examples 1 and 2, as shown in FIGS. 6A and 6B, the female button 2 is disposed at a predetermined position on the first surface D1 side of the third fabric C3, and the intermediate button 3 is disposed on the second surface D2 side of the third fabric C3 at a position corresponding to the predetermined position of the female button 2. The intermediate button 3 is pressed against the female button 2 in the F1 direction through the third fabric C3, and the female button 2 and the intermediate button 3 are elastically engaged at a predetermined position to fasten and fix the third fabric C3.

[0048] Next, as shown in FIG. 6C, the opening 53 of the U-shaped clip 5 is opened in the D direction to fasten the fourth fabric C4. The U-shaped clip 5 has a plurality of tooth surfaces 52 on its inner surface, and each tooth surface is formed such that the inclination angle on the opening 53 side is small and the inclination angle on the back side is large. Therefore, the fourth fabric C4 can be smoothly inserted and sandwiched between the U-shaped clips 5. However, after insertion, since the U-shaped clip 5 is formed to be biased in the inward closing direction and the plurality of facing tooth surfaces 52 are formed to engage with each other, the fourth fabric C4 does not come off unless the opening 53 of the U-shaped clip 5 is intentionally opened and pulled out. At this time, the U-shaped clip 5 is disposed such that the male button portion 51 is located near the predetermined position of the intermediate button 3. Then, by pressing the male button portion 51 against the intermediate button 3 in the F2 direction and snap-fitting, the intermediate button 3 and the U-shaped clip 5 are connected, and the third and fourth fabrics C3 and C4 can be connected.

[0049] In the snap button 1 with variable fastening position of Example 1, the female button 2 and the intermediate button 3 are elastically engaged to fasten and fix the first fabric C1. Next, the male button 4 and the intermediate button 3 are elastically engaged to fasten the second fabric C2, fastening the first and second fabrics C1 and C2. In the snap button 102 with variable fastening position of Example 2, the female button 2 and the intermediate button 3 are elastically engaged to fasten and fix the fabric C1, and the elongated male button 4' and the reverse female button 2' are elastically engaged to fasten and fix the fabric C2. Then, the intermediate button 3 and the elongated male button 4' are snap-fitted to fasten the first and second fabrics C1 and C2. On the other hand, in the snap button 201 with variable fastening position of Example 3, the female button 2 and the intermediate button 3 are elastically engaged at a predetermined position to fasten and fix the third fabric C3. Next, the thick or hard fourth fabric C4 is fastened near the optimal position by the U-shaped clip 5, and the male button portion 51 of the U-shaped clip 5 is snap-fitted with the intermediate button 3 to connect the third and fourth fabrics C3 and C4.

[0050] Here, by pressing the pressing portion 21 of the female button 2, the elastic engagement between the female button 2 and the intermediate button 3 through the third fabric C3 can be released, which is the same as in Examples 1 and 2. Then, the fourth fabric C4 is fastened by the U-shaped clip 5 near the optimal position according to the change in body shape at that time. By pressing the pressing portion 21 while maintaining the facing relationship between the female button 2 and the intermediate button 3 and sliding with the third fabric C3 sandwiched in the disengaged state, the male button portion 51 on the side surface of the U-shaped clip 5 can be snap-fitted at the optimal position.

[0051] In Examples 1 and 2, application examples where the first and second fabrics C1 and C2 are a shirt S and pants P were illustrated. Although the snap button 201 with variable fastening position of this example is also applicable to a shirt S and pants P, in order to more clearly illustrate the characteristics of the snap button 201 with variable fastening position of Example 3, which is also applicable to thick or hard fabrics where elastic engagement is difficult, the following will specifically describe the case where the third and fourth fabrics C3 and C4 are a dress shirt Y and trousers (or skirt) T.

[0052] The purpose of applying the variable fastening position snap button 201 of the present invention to the shirt Y and the trousers T is, as in Embodiments 1 and 2, to enable the shirt Y and the trousers T to be worn on the body regardless of the body size change and the waist size or belt of the trousers T. FIG. 7 is a perspective view showing the arrangement when the shirt Y and the trousers T are worn on the body B with the variable fastening position snap button 201. FIG. 8 is an enlarged longitudinal sectional view when fastening the shirt Y and the trousers T with the variable fastening position snap button 201 of the present embodiment. Also in this Embodiment 3, the female button 2 and the intermediate button 3 are elastically engaged through the shirt Y to fasten the shirt Y and fix both buttons. However, different from Embodiments 1 and 2, the trousers T are fastened with a U-shaped clip 5 having a male button portion 51 on the side at the outer edge (belt line) around the waist of the trousers T near the optimum position according to the body shape, and the shirt Y and the trousers T are connected by snap-fitting the intermediate button 3 and the male button portion 51. Other structures and functions are the same as those in Embodiments 1 and 2.

[0053] That is, the female button 2 is arranged at a predetermined position on the first surface D1 side of the shirt Y, the intermediate button 3 is arranged on the second surface D2 side of the shirt Y at a position corresponding to the predetermined position of the female button 2, and by pressing the intermediate button 3 against the female button 2 in the F1 direction through the shirt Y, the female button 2 and the intermediate button 3 are elastically engaged at the predetermined position to fasten the shirt Y and fix both buttons. Next, the trousers T are fastened at the optimum position conforming to the body shape of the belt line with a U-shaped clip 5 having a male button portion 51 on the side. Then, the male button portion 51 is pressed in the F2 direction to snap-fit with the intermediate button 3, thereby connecting the shirt Y and the trousers T.

[0054] Here, similar to Embodiments 1 and 2, by pressing the pressing portion 21 of the female button 2, the elastic engagement between the female button 2 and the intermediate button 3 via the shirt Y can be released, and the shirt Y can be taken off. Here, since the intermediate button 3 is elastically engaged with the male button 51, it will not become disengaged. Further, while maintaining the facing relationship between the female button 2 and the intermediate button 3, the pressing portion 21 is pressed to sandwich the shirt Y in a disengaged state and slide it. By stopping pressing the pressing portion 21 at the optimal position corresponding to the body shape change at that time, or at the position where it fits with the male button portion 51 and re - engaging the two buttons elastically, the fastening position can be easily changed. Then, the female button 2 and the intermediate button 3 are fixed at the optimal position, and the male button portion 51 can also be fixed at the optimal position. However, if the snap fit between the intermediate button 3 and the male button portion 51 is released, the shirt Y and the trousers T can be easily separated as many times as needed, similar to changing a normal shirt and trousers.

[0055] As described above, also in Embodiment 3, with the position - variable snap button 201, the shirt Y and the trousers T can be securely fastened vertically like clothes. So, even if the body shape changes and the body circumference increases or decreases, by sandwiching the belt line of the optimal position portion of the trousers T with the U - shaped clip 5 according to the body shape and snap - fitting the intermediate button 3 and the male button portion 51, the shirt Y and the trousers T can be connected and worn on the body B. Therefore, there is no need to fasten the trousers T to the body B with a belt or the like, which is healthy both respiratorily and circulatorily, and the trousers T will not shift or the shirt Y will not protrude. When the body circumference decreases, as described in Embodiment 1, for example, the number of snap - button sets can be set to 4, and the length between each snap button can be adjusted to be shorter to reduce the overall body - circumference size, enabling wearing on the body.

[0056] Furthermore, similar to Embodiments 1 and 2, in this Embodiment 3 as well, the elastic engagement between the female button 2 and the intermediate button 3 is strong and is not released unless the pressing portion 21 is intentionally pressed, and it does not become disengaged even when washed. That is, while the female button 2 and the intermediate button 3 via the shirt Y can be semi-permanently fixed at the fastening position, the elastic engagement between the female button 2 and the intermediate button 3 can be released as needed to change the fastening position. Furthermore, the U-shaped clip 5 and the trousers T also do not become detached from the trousers T, and do not become disengaged even when washed, unless the opening 53 of the U-shaped clip 5 is intentionally opened against the biasing force in the closing direction. That is, while the U-shaped clip 5 can be semi-permanently fixed at the optimal position on the trousers T, the opening 53 can be opened at any time according to changes in body shape to separate the U-shaped clip 5 from the trousers T and change the optimal fastening position.

[0057] Incidentally, Patent Document 2, Japanese Patent Application Laid-Open No. 2016-094691, and Patent Document 3, US Patent 07398558, disclose a suspender that connects an upper garment and trousers to prevent the trousers from falling, but they differ from the present invention in that there is no structure corresponding to the intermediate button of the present invention and there is no description regarding the purpose. That is, the intermediate button of the present invention has a structure that engages with a female button via an upper garment to fix the positions of both buttons and also elastically engages with a male button (portion), and connects the upper garment and the trousers by the elastic engagement with the male button (portion). Furthermore, although the male button (portion) of the U-shaped clip of the present invention has a variable fastening position, the trouser-side fasteners in both patent documents are also different in that they are fixed to the trousers by support means such as screws or fastener elements. Therefore, the ideas, purposes, structures, and functions of the fasteners of the present invention and those of both patent documents are fundamentally different, and it is impossible to conceive of the fastener of the present invention. Also, in both patent documents, like the name "suspender", the fastening position is limited to the vicinity of the belt line, but the snap buttons with variable fastening positions in the broad sense including Embodiments 1 and 2 of the present invention can be freely changed in fastening position and can be fastened not only in the vicinity of the belt line but also almost throughout the entire area of the clothing.

[0058] (Modification example) Conventional trousers usually have a front opening part, and the upper part of the trousers is fastened and opened or closed with hooks or buttons. However, when the body shape changes and the waist circumference increases, even if the variable fastening position snap button 201 of Example 3 is worn on the body like an overalls, it may be difficult to fasten those hooks or buttons. Therefore, when using the variable fastening position snap button 201, it is conceivable to remove those hooks or buttons and cover them with a belt or the like. However, the variable fastening position snap button 301 shown below can also handle this situation.

[0059] FIG. 9 is an enlarged cross-sectional view showing a variable fastening position snap button 301 according to a modified example of Example 3. Since the variable fastening position snap button 301 of the modified example only differs in some configurations from the variable fastening position snap button 201 of Example 3, the same components are denoted by the same or similar reference numerals. FIG. 9A shows a second U-shaped clip 6 having an intermediate button portion 61 on the outer surface on the D2 side and fastening the fabric C5. FIG. 9B shows a first U-shaped clip 5 having a male button portion 51 on the outer surface on the D1 side and fastening the fabric C6. Note that the basic shape and function of the intermediate button portion 61 are the same as those of the intermediate button 3 of Examples 1 and 2, and it is integrally formed with the second U-shaped clip 6. Similarly, the basic shape and function of the male button portion 51 are also the same as those of the male button 4 of Examples 1 and 2. In this modified example, like Example 3, the male button portion 51 is integrally formed with the first U-shaped clip 5. Needless to say, the variable fastening position snap button of the present invention can be reduced or enlarged in size according to the part of the fabric to be used. However, the variable fastening position snap button 301 of this modified example applied to the front opening part of the trousers is smaller than the variable fastening position snap button 201 of Example 3.

[0060] When fastening the fabrics C6 and C5 with the two U-shaped clips 5 and 6 respectively, by adjusting the fastening length, the front opening can be adjusted according to the body shape. That is, the two U-shaped clips can fasten the fabric sufficiently without sandwiching the fabric to the deepest part. If the fabric is sandwiched shallower, the front opening can be loosened more. The length of loosening the front opening is about 1 - 1.5 cm. When the length of fastening the fabric with the two U-shaped clips is determined, by pressing the male button part 51 in the F direction against the intermediate button part 61 and snap-fitting, the fabrics C5 and C6 such as the front opening of the trousers can be connected. That is, the hook or button at the front opening can be replaced with the snap button 301 with variable fastening position of the modification example.

[0061] For the neck and body parts of a conventional shirt where buttons cannot be fastened when the body shape changes, if the snap button 301 with variable fastening position of the modification example is further miniaturized and applied, they can be connected. That is, the snap button 301 with variable fastening position of the modification example includes a first U-shaped clip 5 having a male button part 51 on its side surface and a second U-shaped clip 6 having an intermediate button part 61 on the side surface facing the side surface. By sandwiching both sides of the neck and both fabrics of the body part of the shirt with these U-shaped clips and snap-fitting the male button part 51 and the female button part 61 while adjusting the sandwiching position of these two U-shaped clips, it becomes possible to connect both sides of the neck and the body part.

[0062] Also, in the case of a white shirt, the collar and the cuffs of the sleeves are particularly prone to getting dirty or worn out. Even if the main body of the white shirt is clean, it may have to be sent for cleaning or become unusable early. Many solutions to this problem have been proposed, and there are also commercially available products that separate and connect the collar edge and the main body of the white shirt with snap buttons for replacement. However, depending on the manufacturer and the product, if the sizes and fastening positions of the snap buttons are different, they cannot be properly connected. However, if the fastening position variable snap button 301 of this modification example is further miniaturized, and the alternative collar edge and the main body of the white shirt are sandwiched between the two U-shaped clips respectively, and while adjusting the fastening position, the male button part and the intermediate button part of the two U-shaped clips are snap-fitted, the two parts can be easily separated and connected and made interchangeable. Also, if the parts of the collar edge and the cuffs can be easily connected and exchanged from the beginning with the fastening position variable snap button of this modification example, the old collar edge and cuffs can be removed and new collar edge and cuff parts of different colors and shapes can be attached. The whole white shirt can be used for a long time, and the variety and fashionability can also be enjoyed with the same white shirt.

[0063] As described above, an effective, simple, and practical fastening position variable snap button has been explained. The fastening position variable snap button of the present invention has further application examples and effects as follows. That is, (1) If it is difficult to fasten the rubber elastic body of conventional pants, even if the rubber elastic body is removed or cut, the shirt and the pants can be connected with the fastening position variable snap button of the present invention and worn on the body. That is, pants that do not require a rubber elastic body or trousers (skirts) that do not require a belt can be created.

[0064] (2) Even for people of normal build, when performing intense work or exercise, the dress shirt (or shirt) may protrude from the trousers (or pants), causing the clothing to become disheveled. Especially in sports such as soccer and tennis, during the competition, the upper garment may protrude or be pulled, resulting in the clothing becoming disheveled. However, tightly fastening the pants to the body with a rubber elastic body or the like may lead to a decrease in breathing and motor functions. However, with the snap button with variable fastening position of the present invention, the upper and lower clothing can be reliably connected. Structurally, the dress shirt (shirt) is connected and fixed to the trousers (pants) at three or more points. Therefore, the dress shirt (shirt) does not protrude above the trousers (pants), and the clothing does not become disheveled. In addition, when performing even more intense work or exercise, it goes without saying that if the dress shirt (shirt) is fastened to the trousers (pants) at four or more points instead of just three as described above, it can be more reliably connected.

[0065] (3) There is a suspender as an equipment for fastening the dress shirt and trousers vertically. However, the suspender hung from the shoulders is often not used because it is fashionably uncoordinated, troublesome, and the shoulders are prone to stiffness. However, the snap button 201 with variable fastening position of the present invention can easily and reliably fasten the dress shirt Y and the trousers T vertically in an inconspicuous form, without problems such as shoulder stiffness, and serves as an alternative to the suspender.

[0066] (4) It can be used as clothing for obese people, pregnant women, hospital patients, and examination patients. Different from normal body shapes, obese people do not have a constriction between the abdomen and the waist, and even if they fasten their trousers with a belt, they cannot be worn around the waist and are prone to slipping off. However, with the snap button with variable fastening position of the present invention, the upper and lower clothing can be securely connected at any time, and problems such as body constriction and slipping off can be solved. Pregnant women also have a changing waist circumference every day, but with the snap button with variable fastening position of the present invention, the upper and lower clothing can be securely connected at any time. As clothing for hospital patients and care recipients who cannot be long-constrained by the rubber band of trousers, the snap button with variable fastening position of the present invention is useful because it can securely connect the upper and lower clothing at any time. Furthermore, with the snap button with variable fastening position of the present invention, trousers worn on the body at three locations in total, two at the front waist and one at the backbone, can be used for toileting by removing the fastener at the backbone part, so it is also useful for some hospital patients, examinations, and clothing for care recipients.

[0067] (5) In each of the above embodiments, the snap button with variable fastening position was mainly attached near the end of the fabric to connect the clothing. However, the snap button with variable fastening position can be attached anywhere, not just near the end of the fabric. That is, even if the shirt (blouse) is connected in a form that hangs outside the trousers, the above function of preventing the trousers or pants from slipping off can be achieved. That is, there is also a fashion (so-called shirt out) in which the shirt (blouse) is put outside the trousers, and while achieving the above connection function, the fashionability can be satisfied.
