Description

[Technical field]

[0001] The present invention relates to a nail attachment device that can be easily and stably fixed to the nail plate edge portion (hereinafter referred to as the nail plate edge portion) having the nail plate side edge and the nail plate free edge of the nail of the fingernail or toenail. [Background technology]

[0002] Nail accessories are required to be attached to the nail plate or the edge of the nail plate without damaging the aesthetics, and the means for attaching them to the nail are often ultraviolet-curing resins, epoxy resins, or other resin-based adhesives or pressure sensitive adhesives, double-sided tapes, etc., which are called nail glues. However, when attaching expensive jewelry or imitation jewelry such as crystals and rhinestones to the nail plate, the above-mentioned adhesive means are not suitable for long-term fixation because moisture from the nail bed gets between the nail plate and the adhesive surface, and the adhesive surface is easily degraded due to fatigue caused by repeated nail deformation due to external pressure, making it easy to peel off from the adhesive surface. In addition, if more tapes or adhesives are used to improve adhesion, the surface of the nail attachment will be partially or entirely covered, making it look bad as an accessory for decorating the nail.

[0003] In addition, an ingrown nail corrector using plastic processing, as described in Patent Document 1, invented by the present inventor, has also been proposed. This is a means of correcting the deformed nail edge of an ingrown nail by attaching the corrector to the deformed nail edge and crushing the deformed nail edge and the corrector body together. However, there is a problem in that there is no description of a function that allows the corrector body to be fixed to the deformed nail edge after correction. The seam processing described in the document is to prevent it from falling off after correction, and is not described as a fixing means. In addition, a nail protector using a plastic material to protect the cracked part of the nail edge has been proposed, as described in Patent Document 2, which was invented by the present inventor. The nail protector also uses a clamping and fixing means by plastic processing that can keep the cracked part of the nail edge closed, but the clamping and fixing means is a fixing means for preventing the opening and closing movement by closing the cracked part of the cracked part of the nail edge, and there is a problem in that there is no description of a function for fixing the nail protector to the nail edge. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4341849 [Patent Document 2] Patent No. 7094935 Summary of the Invention [Problem to be solved by the invention]

[0005] To attach jewelry such as the above-mentioned jewels and imitation jewels, ultraviolet curing resins, epoxy resins, fixing tapes, adhesives, and glues are used on the nail surface, such as nail glue. However, if the glue or tape is visible on the nail surface, it looks bad, and if it is applied improperly, it can cause problems such as poor adhesion as well as poor appearance.

[0006] In addition, in the plastic nail deformity corrector as in Patent Document 1, no fixing means is described, and the deformed nail that has been corrected to a flat shape can be attached to the nail plate edge by the elastic force that tries to restore the deformed nail to a curved shape. However, in the case of a nail shape formed to be approximately flat, the restoring force of the deformed nail is lost, and the nail insertion opening of the deformed nail corrector does not have the function of clamping the nail, so it is easily removed. In addition, adhesives and fixing tapes are weak against water, and are easily peeled off and removed when bathing or washing hands and feet. In addition, there is no description of the use as an accessory, and the use as such is not considered. In addition, although a seam processing to prevent the deformed nail corrector from falling off is described, the function of fixing to the nail plate edge is not described. There is no description of an elastic function being applied to the seam processing part, so there is a problem that the seam part made of the same plastic material as the main body is flattened when crushed, and easily slides off the nail plate edge and is removed.

[0007] In addition, the nail protection device described in Patent Document 2 does not describe a function for fastening the nail protection device to the main body or a function for stably fastening the nail protection device. In addition, there is no description of its use as an accessory, and the function is not taken into consideration. Moreover, when the nail protector is clamped and held in the nail edge cleft embedded in the nail fold, it is necessary to insert and arrange the cleft nail plate part using a clamping hand tool, and then to crush the nail protector together with the nail plate from above and below. At that time, it is necessary to insert the tip of the lower leg of the clamping hand tool from the nail fold direction into the nail bed part on the back side of the nail plate of the nail edge cleft part, and in this case, there is a problem that it is necessary to incise the back side of the nail edge cleft and the nail bed or peel off the natural nail to make a gap for the insertion so that the tip of the lower leg can enter between the back side of the nail plate of the nail edge cleft part and the nail bed part.

[0008] The object of the present invention is to provide a nail attachment device that can be used for a variety of purposes, such as a nail ornament made of precious metals, a nail attachment device with a stone setting that allows jewel or imitation jewel ornaments to be fixed to the upper leg, a nail ornament on which engraving or casting can be applied to the upper leg, a flattening and fixing device for nail correction, a device to prevent ingrown nails at the nail edge, a fixing device to close cracked nails, and an installation device used in pairs on both the left and right nail edges to bridge elastic restoring girders for correcting deformed nails, decorative base plates, false nails, etc. over the nail plate. [Means for solving the problem]

[0009] The nail attachment device of the present invention for solving the above problems is composed of the following technical means.

[0010] The configuration described in claim 1 of the present invention is a body formed in an approximately C-shaped or U-shaped shape with an open tip, made of a single material, a composite material, or a composite material in which a single material is inserted into a resin material, and the body is provided with a plastic crushing area that can be plastically deformed by crushing using a manual clamping tool in the area from the front side, excluding the vicinity of the tips of the upper and lower legs that face each other vertically when viewed from the side of the body, to a bifurcated branch part that is the same width as the left and right width of the upper and lower legs when viewed from above, or narrower than the left and right width, or protrudes outward from the left and right width, and the tip parts of the upper and lower legs are separated from each other and have a nail insertion separation part into which the nail plate edge part can be inserted.

[0011] The vicinity of the tip of the upper leg is curved or substantially linearly bent downward or substantially inward so that the tip edge of the leg contacts the nail, and the tip edge contacting the nail forms a downward-facing claw contact surface tooth portion that is flat or substantially wavy in front view. The vicinity of the tip of the lower leg is curved or substantially linearly bent upward or substantially inward so that the tip edge of the leg contacts the nail, and the tip edge contacting the nail forms an upward-facing claw contact surface tooth portion that is flat or substantially wavy in front view, provided on each of the upper and lower legs.

[0012] In addition, after the nail edge portion is inserted and disposed in the nail insertion separation portion, the nail insertion separation portion is closed by the urging force that crushes the plastic crushing area. Even at that time, the upper and lower nail contact surface tooth portions are not crushed and deformed, and at least the upper and lower nail contact surface tooth portions have the rigidity to bite the nail edge as a pair, or when used to tilt by the pressurized urging force, the upper and lower nail contact surface tooth portions are made of an elastic material and generate a urging force that generates a clamping pressure due to the elastic recovery, thereby elastically biting the nail edge portion, thereby forming an interlocking portion having each of the functions described above.

[0013] Thus, the invention described in claim 1 is a nail attachment device and nail ornament, characterized in that after the nail plate edge portion is inserted and arranged in the nail insertion separation portion, the plastic crushing processing area is crushed so that the biting portion can bite and fix the nail plate edge portion.

[0014] The invention described in claim 2 relates to a nail attachment device and nail ornament, characterized in that at least one of the upper leg and lower leg described in claim 1 is separated into two or more legs and arranged approximately toward both the left and right ends of the bifurcated branch portion in a plan view.

[0015] The invention described in claim 3 is the nail attachment device and nail accessory described in claim 1, characterized in that the bifurcated branch portion described in claim 1 is spaced apart and arranged at the rear end of the leg and approximately on both the left and right ends when viewed in a plane, so as to form two or more bifurcated branches. Effect of the Invention

[0016] The present invention has the following advantages.

[0017] As described above, according to the invention of claim 1, By setting the plastically crushed area in the area from the front side to the bifurcated part on the rear end side, excluding the vicinity of the tips of the upper and lower legs, it is also possible to provide the plastically crushed area in an outer area where there is no nail, excluding the nail plate edge part. As a result, in order to clamp the bite part at the tip of the opening part formed by the upper and lower legs of the conventional nail attachment device to the nail plate edge part using a clamping hand tool, in order to insert the lower leg part of the hand tool between the back side of the nail plate edge part and the nail bed part so that it can reach the tip bite part, it was necessary to perform a dangerous operation such as peeling the nail edge part from the nail bed part. However, according to the present invention, by crushing the plastically crushed area without directly crushing the tip bite part of the legs, the bite part can be closed and bitten by the force of the crushing, and therefore the effect of being able to safely bite without damaging the nail fold or nail bed was obtained.

[0018] Furthermore, if the nail biting portion that bites into the nail is directly crushed, the erect nail contact surface tooth portion will fall over and be crushed, which may raise the risk of losing the biting function; however, by crushing the plastic crushing area that is provided away from the nail contact surface tooth portion, the nail contact surface tooth portion will not be crushed and a stable biting effect can be obtained.

[0019] In addition, the effect of the nail attachment device that can be fixed to the nail plate edge without using fixing materials that impair the appearance, such as fixing tape or adhesive, is as a precious metal nail accessory, or as a nail attachment device with stone setting such as bezel setting or carved setting that can fix jewels or imitation jewels to the upper leg, or as a nail distortion prevention device, or as a nail edge nail ingrown prevention device, or as a fixing device for closing and fixing a crack that has developed in the lateral or tip nail edge, or as an installation device for bridging and fixing an elastic restoration bridge girder for correcting deformed nails, a decorative base plate, or a false nail, etc., on the nail plate. In addition, by utilizing the effect of the biting, it can be used as a fastener for nail ornaments or a joint device for nail accessories. In addition, in order to promote the effect of the biting, a means for further promoting the biting may be taken by digging an insertion groove or providing an insertion hole in the nail plate edge where the upper and lower nail contact surface teeth contact.

[0020] According to the invention of claim 2, at least one of the upper and lower legs is separated into two or more legs and arranged at both ends of the bifurcated branch in plan view, so that the nail attachment device attached to the nail can be less exposed from the nail plate side in plan view, and has an effect of being inconspicuous. In addition, the shape of the upper leg separated into two legs has an effect of making stone setting processing easy.

[0021] According to the invention of claim 3, the area of ​​the upper leg can be enlarged to a size that allows the upper leg exposed on the nail plate to be decorated or studded with jewels. For example, when the upper leg is large enough to cover the nail plate surface, the upper leg can be engraved, made into a false nail shaped like a beautiful nail, used as a false nail for playing guitar, or used as nail accessories such as nail rings and nail piercings. The width direction of the upper leg can be made to extend beyond the nail plate or protrude from the tip edge of the nail plate toward the tip direction, regardless of the size of the nail plate, and the location and number of the bifurcated branches can be freely arranged on the rear end side of the leg, regardless of the shape of the upper leg, thereby achieving the effect of becoming a canvas or a sculpture that expresses the design sensibility of the practitioner.
