1 is a view showing a disassembled state of a metal button for allergy-free clothing according to the present invention. FIG. 2 is a view showing an assembled state of the coupling needle 120 of the metal button for allergy-free clothing of FIG. 1 . 3 is a view showing a state in which a metal button for allergy-free clothing according to the present invention is coupled to clothing.

1 to 3, the metal button for allergy-free clothing according to the present invention includes a button body 10 and a fixing nail 100, and the button body 10 and the fixing nail 100 are made of a metal material. is formed with In particular, the surface of the fixing nail 100 in contact with the body may be formed of a material containing titanium (Ti). Titanium is a metal with high human affinity and does not cause allergies. Therefore, as the surface of the fixing nail 100 in contact with the body is formed of a material containing titanium, it is possible to reduce skin allergy.

The metal button for allergy-free clothing according to the present invention has a shape similar to the existing canton button and rocking button. A metal button for allergy-free clothing includes a button body 10 and a fixing nail 100, and a fixing nail in a state in which a fabric (clothing, etc.) 1 is interposed between the button body 10 and the fixing nail 100 (100) can penetrate the fabric (1) and be inserted into the button body (10). Accordingly, the button body 10 may be fixed to one side of the fabric 1 with a fixing nail 100. One end of the button body 10 is fixed to one side of the fabric 1 and the other end can swing freely. The button body 10 may pass through an external button hole while being fixed to one surface of the fabric 1. Metal buttons for allergy-free clothing may be applied to various clothing products such as pants and jackets. In particular, it can be applied to a location where it is easy to come into contact with the wearer's body, but the application location is not limited.

The fixing nail 100 may include a support plate 110, a coupling needle 120, and a cover member 130.

The support plate 110 may be formed in a plate shape. The support plate 110 may be formed in a thin cylindrical shape, but the shape of the support plate 110 is not limited in the present invention. The support plate 110 may be located on the other side of the fabric 1 (opposite to the side where the button body 10 is located). A protrusion may be formed on one surface of the support plate 110 . These protrusions can increase the contact area with respect to the fabric 1 and strengthen the frictional force, so that the support plate 110 can be firmly coupled to the fabric 1 .

The support plate 110 may be formed of a material including aluminum (Al). For example, the support plate 110 may be formed of a metal having aluminum as a main component and containing impurities. For example, the support plate 110 may be formed of an alloy having aluminum as a main component.

The coupling needle 120 may be coupled to one surface of the support plate 110 and inserted into the button body 10 through the fabric 1. Coupling needle 120 may be formed vertically long on one side of the support plate 110. An end of the coupling needle 120 may be formed sharp.

Coupling needle 120 may be formed of a material containing aluminum (Al). For example, the bonding needle 120 may be formed of a metal having aluminum as a main component and containing impurities. For example, the coupling needle 120 may be formed of an alloy whose main component is aluminum.

The coupling needle 120 may be deformed (left and right crushed or bent) by an external force after being inserted into the button body 10, and thus may not be caught on the internal structure of the button body 10 and fall out. That is, the coupling needle 120 may be fixed while being inserted into the button body 10 . Since the fabric 1 is interposed between the support plate 110 and the button body 10, the fixing nail 100, the fabric 1, and the button body 10 can be fixed together in a coupled state.

The cover member 130 may cover the other surface of the support plate 110 so that the other surface of the support plate 110 does not come into contact with the wearer's body. That is, instead of the other surface of the support plate 110, the cover member 130 may contact the body.

The cover member 130 may be formed of a material including titanium (Ti). As described above, since titanium has a high affinity for the body, allergy does not occur even when the cover member 130 touches the body. Accordingly, a metal button for allergy-free clothing may be implemented.

The support plate 110 and coupling needle 120 mainly composed of aluminum and the cover member 130 mainly composed of titanium may be bonded together. According to this, it is possible to add only the cover member 130 to the existing nail while using the existing button body 10 and the existing nail as they are.

On the other hand, when titanium is used as a main component until the coupling needle 120 for allergy-free, the coupling needle 120 has high strength and may not be crushed (or bent) within the button body 10. Therefore, the original function of the coupling needle 120 is not impaired by using a separate cover member 130 containing titanium as a main component for allergy free.

The cover member 130 may be formed of a metal containing titanium as a main component and impurities. The cover member 130 may be formed of an alloy containing titanium as a main component. The cover member 130 may be formed of a titanium alloy having the following composition.

Ti-X-Y

0 ≤ X+Y ≤ 30w%

Here, each of X and Y may be at least one selected from Fe, Mn, Cu, Co, Ta, Nb, Zr, and Sn. Metals corresponding to X and Y and the addition ratio (w%) may be determined according to strength, workability, moldability, and the like.

The cover member 130 may be formed in a plate shape covering the other surface of the support plate 110 . The cover member 130 may be attached to the other surface of the support plate 110 .

The cover member 130 may be formed in a shape surrounding not only the other surface of the support plate 110 but also the side surface. The cover member 130 may be formed in a tubular shape. For example, the cover member 130 may be formed in a cylindrical shape. The cover member 130 may include a bottom 131 and a side wall 132 . The bottom 131 may be a circular plate or a polygonal plate. The sidewall 132 may be formed along the circumference of the bottom 131 . The sidewall 132 may be formed around the entire circumference of the bottom 131 . An accommodation space may be provided inside the side wall 132 .

Here, the support plate 110 may be inserted into the accommodation space provided inside the side wall 132 . The bottom 131 of the cover member 130 may cover the other surface of the support plate 110 , and the sidewall 132 of the cover member 130 may cover the side surface of the support plate 110 . Since the cover member 130 is covered on the support plate 110, the support plate 110 may not completely come into contact with the body.

Meanwhile, an undercut 133 may be formed on the sidewall 132 of the support plate 110 . The undercut 133 may protrude inward from the inner circumferential surface of the sidewall 132 . The undercut 133 may be formed at an upper end of the sidewall 132 . The undercut 133 may cover at least a portion of one surface of the support plate 110 . According to the undercut 133, the support plate 110 may not be removed or separated from the accommodation space. That is, the support plate 110 may be caught on the undercut 133 and not fall out. Accordingly, the fastening force between the support plate 110 and the cover member 130 may be increased.

The undercut 133 may be implemented as an inclined surface formed on an inner circumferential surface of the side wall 132 . According to this inclined surface, the cross section (or diameter) of the upper side of the accommodating space may be smaller than the cross section (or diameter) of the lower side. The diameter of the support plate 110 may be larger than the minimum diameter of the receiving space. Therefore, the support plate 110 may be tightly stuck in the accommodation space and not fall out.

Referring to A of FIG. 3 , the inclined surface may descend toward the floor 131 . In addition, the inclined surface may be formed on the entire area of the inner circumferential surface of the side wall 132 . In this case, the inclined surface may be formed such that the cross section of the accommodation space widens toward the floor 131.

Let's look at how the button body 10 and the fixing nail 100 are fastened.

As shown in FIG. 1 , the support plate 110 may be positioned on the cover member 130 in a direction in which the coupling needle 120 is directed toward the button body 10 side. When the support plate 110 and/or the coupling needle 120 is pressed toward the cover member 130, as shown in FIG. 2, the support plate 110 may be inserted into the cover member 130.

Even when the undercut 133 is formed in the cover member 130 , the support plate 110 may be inserted into the receiving space within the cover member 130 by a downward force. The undercut 133 may be opened at the moment when the support plate 110 is loaded, and when the support plate 110 is charged, the undercut 133 may be restored to its original state and the support plate 110 may be fixed.

On the other hand, as the support plate 110 is charged into the receiving space, deformation may occur in a portion (eg, the edge portion of the support plate 110 may be rolled up). 110) can be molded to fit the accommodation space. As a result, since the maximum diameter (lower diameter) of the support plate 110 is greater than the minimum diameter (upper diameter) of the accommodation space, the support plate 110 may not be removed from the accommodation space.

As shown in Figure 3 (a), the button body 10 may be disposed on the fixing nail (100). As shown in FIG. 3 (b), the fabric 1 is placed between the button body 10 and the fixing nail 100, and the coupling needle 120 penetrates the fabric 1 to form a button body 10 can be inserted internally. Subsequently, when the button body 10 is pressed toward the fixing nail 100 using a press or a hammer, the end of the coupling needle 120 is deformed (distorted or bent) and the diameter increases, so the button body 10 ) gets stuck inside and can't get out. As a result, the button body 10, the fabric 1, and the fixing nail 100 can be firmly fastened.

Meanwhile, the button body 10, the fabric 1, the support plate 110, and the cover member 130 may be fastened at the same time. That is, after properly arranging each component up and down, it can be pressed at once using a press or the like. However, it is not limited to this, and the support plate 110 and the cover member 130 are fastened first, and then the button body 10, the fabric 1, and the fixing nail 100 can be pressed at once using a press machine or the like. there is.

Looking at the button body 10 in detail, the button body 10 may include a head 11 and a pillar 12. The head 11 corresponds to the decorative part of the button and is located at the frontmost part. The head 11 may be a circular (or polygonal) plate-shaped body or a ring-shaped plate-shaped body. The pillar 12 is a pillar supporting the head 11 . The pillar 12 may have a cylindrical (or polygonal) shape. An insertion passage through which the coupling needle 120 is inserted may be provided inside the pillar 12 . In addition, a stopper structure for catching the end of the crushed (or bent) coupling needle 120 may be provided at the end of the insertion passage.

The button body 10 may further include a rotating part 13 . The rotating part 13 is fitted inside the pillar 12 and can rotate around the pillar 12 . Rotating part 13 may be inserted into the aforementioned insertion passage. A hole corresponding to the insertion passage is formed in the rotating part 13, and the coupling needle 120 can be inserted into the hole. When there is a rotating part 13, even if the button body 10 is fixed to the fabric 1 by the fixing nail 10, the head 11 and the pillar 12 can rotate.

The button body 10 may be formed of a metal having aluminum as a main component.

4 to 7 are views showing a modified example of the coupling needle 120 of the metal button for allergy-free clothing according to the present invention.

Referring to FIG. 4 , the undercut 133 may protrude vertically from the inner circumferential surface of the side wall 132 . Referring to FIG. 4( a ) , the undercut 133 includes an inclined surface, but the inclined surface may be formed only on a portion of the inner circumferential surface of the side wall 132 . According to FIG. 4(a), deformation of the shape when the support plate 110 is loaded into the accommodation space can be minimized. Referring to FIG. 4(b) , the undercut 133 includes an inclined surface, and the inclined surface may be located on an upper side. According to FIG. 4(b) , since the support plate 110 moves downward along the inclined surface and can be charged into the accommodating space, the external force for being charged into the accommodating space can be reduced.

Referring to FIG. 5 , the undercut 133 may protrude vertically from the inner circumferential surface of the sidewall 132 without an inclined surface. Referring to FIG. 5( a ) , the undercut 133 may be formed on the uppermost side of the sidewall 132 . In this case, a contact area between the cover member 130 and the fabric 1 may be increased. Referring to FIG. 5(b) , the undercut 133 may be formed at an intermediate point of the sidewall 132 instead of on the uppermost side.

Figure 5 shows the embodiment of Figure 4 (b). The undercut 133 may be formed in a ring shape at a midpoint of the inner circumferential surface of the cover member 130 instead of on the uppermost side.

Referring to FIG. 6 , the side wall 132 may be formed on a part of the circumference of the bottom 131 , not the whole. In FIG. 6, there is one point where the side wall 132 is broken, but it is not limited thereto. The sidewall 132 may be partitioned into multiple regions. In this case, since the side wall 132 can be easily opened, inserting the support plate 110 into the accommodation space can be facilitated.

Referring to FIG. 7 , the undercut 133 may be omitted. The support plate 110 may be force-fitted into the accommodation space. The support plate 110 may be attached to the bottom 131 and/or the side wall 132 using a separate adhesive member. The support plate 110 may be accommodated into the cover member 130 and welded to the cover member 130 .
