Description

  The present invention relates to a nail deformation prevention device that can be attached to a substantially flat nail to suppress external pressure applied in a direction in which the nail is deformed and prevent nail deformation in advance.

  To keep your toes clean, wear your formal shoes (for example, pointed toe or semi-round toe) or socks with tight toes to keep your toes clean. The part may be bent by the external pressure of the footwear, and the claw edge part may be deformed into a strong curved shape so as to bite into the claw groove part. Further, if the footwear continues to move while wearing the footwear, the nail edge portion may be repeatedly pressed and released, and the nail edge portion may be fatigued and split.

  Moreover, in exercise, there are many scenes in which the weight is put on and stretched from the first and second baseballs to the nail cage during body weight movement (including kicking feet), such as shown in FIGS. 9 (1) to (2). When the nailfold is compressed, the nail edge deforms and bites into the nail groove, and this operation is repeated to cause the nailfold to swell or the soft tissue of the nail groove to lacerate. Even walking is difficult. In addition, since the appearance is essential for athletes, the swelling of the nailfolds is difficult to cure during the exercise, and if the laceration is left untreated, bacterial infection may cause suppuration. It needs to be prevented before it occurs.

A number of nail deformation correction tools for treating wound nails and ingrown nails using an elastic action have been invented. For example, the nail deformation correction tools (Patent Document 1), (Patent Document 2), (Patent Document 3). All of the nail deformation correction tools such as) are for the purpose of treating nail deformation, so even when temporarily treated, the correction tool is bent and attached to the curved shape of the deformed nail. Also, it provides flexibility along the curved shape of the nail. The elastic performance used for the treatment of the nail deformation correction tool is adjusted to an elastic force that can be gradually corrected to a flat shape after being mounted along the already deformed nail. Also from this fact, the pressure resistance and the bending resistance of the nail deformation correction tool allow at least the curved shape of the wound nail. Therefore, when the nail deformation correction tool is mounted on a flat nail, the elastic performance adjusted for the correction treatment has pressure resistance and bending resistance that can be suppressed against external pressure that bends the nail. Is not recognized, and no description of suppression of external pressure is found in each document.

  For example, the nail edge is bent by a shoe having a narrow toe as shown in FIGS. 8 (1) to 8 (2) or a toe load during exercise as shown in FIGS. 9 (1) and 9 (2). When external pressure is applied, the nail edge is deformed and bites into the nail groove, causing pain and swelling of the nailfold soft tissue.

  The present invention attaches to the nail a claw-shaped protector that has sufficient pressure resistance and bending resistance to suppress the bending deformation of the nail to such an extent that the nail edge bites into the nail groove due to external pressure applied to the nail edge. Thus, an object of the present invention is to provide a nail deformation preventing device that can prevent nail deformation caused by the external pressure by the action of the nail shape protector and diseases around the nail cage due to nail deformation.

In order to solve the above-described problems, the nail deformation preventing method according to the present invention has a substantially flat nail left and right nail edge 11 and nail as shown in the usage examples of FIGS. The slits of the fasteners 2a respectively disposed at the left and right nail edges of the nail width direction both ends of the claw-shaped protector 1a having a flat plate-like bending resistance formed with a length that can be installed between the widths. The nail-shaped protector 1a is installed on the substantially flat nail plate 13 by being inserted into 3 and sandwiched.
Accordingly, the action of the claw-shaped protector 1a with enhanced flex resistance can suppress external pressure applied in the direction in which the claw edge 11 is deformed, and can prevent the claw from being deformed.
In mounting, the claw-shaped protector A may be provided so that part or all of the claw-shaped protector A is in contact with the nail plate 12, and the nail-shaped protector A and the nail plate 12 may be fixed with an adhesive. .

  In the example of the second invention shown in FIG. 3, as shown in the perspective view of FIG. 3 (a), the claw-shaped protector 1b is formed by extending the claw-shaped protector 1b that is long in the claw width direction. A rod-shaped or linear locking portion 4 is formed at one end portion in the longitudinal direction. In addition, in order to simplify the production, the shape of the claw-shaped protector 1b may be formed in the same bar shape or linear shape as the locking portion 4 without impairing performance. Further, the fastener 2b shown in the perspective view of FIG. 3B is provided with a mounting hole 5 through which the engaging portion 4 can be inserted or fitted, and the fastener 2a shown in FIG. Another form.

In addition, in the case of the fastener 2b that can be fixed in a sandwiched manner using an elastic action, the material is appropriately selected from, for example, a metal, a resin, or an elastomer having elasticity, and is molded.

FIG. 3C shows an example of use of the nail deformation preventing tool B.
The nail deformation preventing device B of the present invention has a fastener 2b sandwiched between the nail edge portion 11 when replacing the nail shape protector 1b currently installed for some reason with a new nail shape protector 1b. Since only the nail shape protector 1b can be changed without being detached, the nail deformation preventing device A sandwiches the nail edge portion 11 and the nail shape protector 1a when replacing the nail shape protector 1a. Although it is necessary to detach the fastener 2a from the nail edge portion 11 and there is a risk of breakage or loss of the nail edge portion during this attachment / detachment, the nail deformation preventing device B removes the fastener 2b from the nail edge portion 11. It is safe because the claw-shaped protector 1b can be changed without desorption.

  In the example of the third invention shown in FIG. 4, it is difficult to install the fastener 2 on the nail edge 11 as shown in the use examples of FIGS. In this case, as shown in the usage example of FIG. 4 (c), the fastener 2 is mounted from the front surface of the nail tip 14 at substantially right and left corners of the tip of the nail. This is a nail deformation preventing tool C characterized in that the protector 1a can be installed on the nail.

  Although the nail | claw of a 1st eyelid is not deform | transforming, the nail | claw edge part 11 repeatedly irritate | stimulates the nail | claw groove part 13 by external pressure, and the nailfold part 10 may swell. Although the nail deformation preventing device B is worn in order not to worsen the symptoms of the nailfold portion 10, the contact of the fastener 2 with the nail groove portion 13 is not only painful, but the swelling portion may be torn, which is dangerous. The fastener 2b is disposed at substantially the left and right corners of the front end of the nail, and the nail portion in front of the nail tip 14 and the nail-shaped protector 1a are inserted and sandwiched in the slit 3 of the fastener 2b, thereby ensuring safety. In addition, the nail deformation preventing device C can be installed.

  FIG. 5 is an example of the fourth invention, and FIG. 6 is an example of the fifth invention. The nail deformation preventing devices A to C are structurally protrusive and are prone to breakage by catching stockings or footwear. In order to prevent the damage of the footwear and from the aesthetic point of view when bare feet, the nail shape protector 1 and the fastener 2 are integrally formed so that the nail deformation preventing device is formed with a smooth surface without protrusions. The nail | claw deformation | transformation prevention tool characterized by having been expressed is represented.
