## Abstract

Provided is an incurvated-nails and ingrown-nails correcting device that uses a magnetic force and that is capable of adjusting the space between a magnet and a magnetic sheet that is placed on a nail. The subject device includes a magnetic sheet that is placed on a nail; the device's main part that includes a body that is attached to the magnetic sheet by using an adhesive agent or by using the magnetic force of the magnet, an arm that extends outward from the body, a head that is arranged at the edge of the arm, and a joint by which the arm is rotatably connected to the body and by which the head is rotatably connected to the arm; and a magnet mounted on the head.

## Claims

### Claim 1

An incurvated-nails and ingrown-nails correcting device that uses a magnetic force, said device comprising:
a magnetic sheet that is attachable on a nail;
a main part of said device, comprising:
a body that is attached to the magnetic sheet by using an adhesive agent or by using the magnetic force of a first magnet;
an arm that extends outward from said body;
a head that is arranged at an edge of said arm on said arm's side that is not attached to the body; and
a first joint, by which the arm is rotatably connected to said body, and a second joint, by which the head is rotatably connected to the arm; and
a second magnet that is mounted on the head;
wherein
the nail is able to be corrected by the magnetic force that is generated between the head and the magnetic sheet.

### Claim 2 (depends on 1)

The device of claim 1, wherein the head is adjustable relative to the arm via the second joint for maintaining a predetermined space defined by the magnet sheet and the second magnet of the head.

### Claim 3 (depends on 1)

The device of claim 1, wherein the body includes a central part and a side part.

### Claim 4 (depends on 3)

The device of claim 3, further comprising a third joint disposed between the central part and the side part, such that the side part is rotatably connected to the central part.

### Claim 5 (depends on 3)

The device of claim 3, wherein the side part includes a first portion and a second portion, such that the central part is sandwiched by the first and second portions of the side part.

### Claim 6 (depends on 3)

The device of claim 3, wherein the first magnet is mounted to the side part.

### Claim 7 (depends on 3)

The device of claim 3, wherein a cut part is disposed between the central part and the side part for allowing bending movement for the body.

### Claim 8 (depends on 1)

The device of claim 1, wherein each joint includes a hinge connection that uses a hinge pin.

### Claim 9 (depends on 1)

The device of claim 1, wherein each joint includes a recess and a projection fitting for allowing rotational movement for the corresponding joint.

### Claim 10 (depends on 1)

The device of claim 1, wherein the device is made of at least partially with at least one of: a metal and a resin.
