Description

  The present invention relates to a chip forming jig for forming a metal chip of an artificial nail attached to a fingernail of a limb.

  In recent years, artificial nails are widely used as accessories for decorating nails of hands and toes, particularly among young women.

  A conventional artificial nail of this type is made of a synthetic resin bent to fit the outer shape of a fingernail and is painted on the outer surface of a thin plate-like chip with a colored paint, or a decorative material on the chip. It is comprised by adhering.

Conventionally, when molding a chip made of such a synthetic resin, after applying a gel-like acrylic resin material to the surface of a base prepared by adjusting to fit each person's nails and drying to obtain a lower layer member, A transparent upper layer member made of the same material as the lower layer member is applied, dried, and peeled off from the base. (For example, refer to Patent Document 1).

  However, in the conventional chip molding method described above, a synthetic resin chip can be molded, but a metal chip cannot be molded.

  Therefore, conventionally, when forming a metal chip, a skilled person took time to form a predetermined curved shape manually, but the shape of the nail of the user of the artificial nail is each Since it is slightly different, there is a problem that when the tip is attached to the nail, a gap is generated between the nail and the tip, or the tip presses the nail. In addition, this method requires a great deal of labor and time, which has been a factor in increasing the cost of metal chips.

  The present invention has been made to solve the above-described problems, and the user of the artificial nail can easily and surely provide a chip that matches the shape of his / her nail, and can form a metal chip. An object of the present invention is to provide a chip forming jig capable of reducing labor and time required and reducing the cost of a metal chip.

  In order to achieve the above-mentioned object, the present invention is a chip forming jig for adjusting the curved shape of a metal tip of an artificial nail attached to a fingernail of a limb, and can be rotated around a support shaft. The two gripping parts are provided on opposite sides of the gripping parts with the support shaft interposed therebetween, and can be rotated in the approaching / separating direction according to the rotation of the gripping parts in the approaching / separating direction. A plurality of concave portions having different curvatures in one rolled portion, and a plurality of convex portions that can be fitted into the concave portions are formed in the other rolled portion. It is characterized by being.

  And it is preferable that the said recessed part and the said convex part are formed so that a curvature may become small as it leaves | separates from the said spindle.

  Moreover, it is preferable that the said rolling part has the shape curved so that a front-end | tip may come below from the virtual centerline which passes along the intermediate part of each said holding part, and the said spindle.

  Furthermore, a notch may be formed at the top of the recess.

  Furthermore, it is preferable that the concave portion and the convex portion are each covered with a flexible member.

  According to the present invention, since the user of the artificial nail can easily and reliably form a curved metal tip that matches the shape of his / her nail, the labor and time required for molding the metal tip can be reduced. In addition, the cost of the metal tip can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a side view showing a chip forming jig according to an embodiment of the present invention, FIG. 2 is a side view showing the chip forming jig, and FIG. 3 is a plan view showing the chip forming jig. 4 is a perspective view showing a chip formed by the chip forming jig.

  The chip forming jig 1 according to the present embodiment has two pairs of gripping portions 3a and 3b that can rotate around a support shaft 2 and gripping portions 3a and 3b opposite to each other with the support shaft 2 interposed therebetween. It is provided with a pair of rolling parts 4a and 4b which are provided so as to be rotatable on the side and can be polymerized with each other.

  The gripping portions 3a and 3b have a shape in which a strip-shaped metal member is curved outward, and is formed so as to be easily gripped by hand.

  As shown in FIG. 2, the rolling portions 4 a and 4 b have a curved shape such that the tip comes below the virtual center line CL passing through the middle of the gripping portions 3 a and 3 b and the support shaft 2. As shown in FIG. 1, when the gripping portions 3a and 3b rotate in the direction of separation from each other, the gripping portions 3a and 3b rotate in the direction of separation from each other. In the same manner, each of them rotates in the proximity direction.

  A plurality of (5 in the drawing) concave portions 6 having different curvatures are formed on the overlapping surface of one rolled portion 4a, and a plurality of convex portions that can be fitted into the concave portion 6 are formed on the overlapping surface of the other rolled portion 4b. Part 7 is formed. The concave portion 6 and the convex portion 7 are each covered with a flexible member (not shown) such as silicon resin. The concave portion 6 and the convex portion 7 are formed so that the curvature in the vicinity of the support shaft 2 where the largest pressing force acts during the polymerization of the rolling portions 4a and 4b is large, and the curvature decreases as the distance from the support shaft 2 increases. It is desirable that

  In the chip forming jig 1 having such a configuration, as shown in FIG. 4, a predetermined portion of the metal chip 5 formed into a general curved shape in a factory or the like is fitted to a fingernail of a user. Then, the concave portion 6 and the convex portion 7 having a desired curvature are selected and sandwiched, and the gripping portions 3 a and 3 b are rotated in the proximity direction with respect to the support shaft 2. Then, according to the rotation of the gripping portions 3a and 3b in the proximity direction, the rolling portions 4a and 4b rotate in the proximity direction around the support shaft 2, and the convex portion 7 is fitted in the concave portion 6, and the rolling portion 4a. 4b polymerize to each other. As a result, a curved shape having a desired curvature is formed at a predetermined portion of the metal tip 5.

  As described above, according to the chip forming jig 1, not only a skilled person but also a user of an artificial nail can easily and reliably form a curved metal chip 5 that matches the shape of his / her nail. Therefore, there is no possibility that a gap is generated between the nail and the chip when the chip is attached to the nail, or the chip presses the nail. Further, the labor and time required for forming the metal tip 5 can be reduced, and the cost of the metal tip can be reduced.

  Further, the concave portion 6 and the convex portion 7 are formed so that the curvature gradually decreases as the distance from the support shaft 2 increases. A large pressing force acts on the chip 5 having a large curvature, and the chip 5 having a small curvature acts on the chip 5 having a small curvature. Since a small pressing force acts, it is possible to easily and reliably form a wide variety of curved tips 5 suitable for the user's nails.

  Furthermore, the rolling parts 4a, 4b have a shape that is curved so that the tip comes downward from the virtual center line CL passing through the middle of the gripping parts 3a, 3b and the support shaft 2, so that the posture is easy. The curved shape of the chip 5 can be adjusted, and the chip 5 can be easily visually recognized during the adjustment work. Therefore, it is possible to improve work efficiency and improve productivity.

  Furthermore, since the concave portion 6 and the convex portion 7 are each covered with a flexible member, the chip 5 surface can be molded without damaging the surface of the chip 5 during molding of the chip 5. it can.

  In addition, as shown in FIG. 5, you may form the notch part 8 in the top part of the recessed part 6, and even if a decoration body protrudes and is attached on the chip | tip 5 in this case, the decoration body is By loosely fitting the cutout portion 8, the curved shape of the chip 5 can be easily and reliably adjusted without damaging the decorative body.
