Description

nail file

The present invention relates to a file for polishing nails, and more specifically, it does not slip in the hand, and the nail trimming process is easy and can be trimmed without effort, so that the elderly can use it easily and can easily remove dead skin cells around the nails. It relates to a file for sharpening nails that can be used, is convenient and safe.

Recently, as the quality of life has improved, interest in leisure, health, beauty, etc. has increased. In particular, women who pursue beauty are paying great attention to the beauty of their fingernails or toenails as well as their face or skin.

Accordingly, nail care shops that professionally manage nails are widely prevalent, and various nail grooming tools for polishing and polishing nails to improve the beauty of nails are being released.

As a conventional nail care tool, first, as exemplified in Laid-Open Patent Publication No. 10-2014-0058232, a cushion layer is attached to a stick-shaped body, and an abrasive layer to which stone powder is adhered is attached to the cushion layer. there is a composition

However, in the case of such a conventional configuration, since the abrasive layer containing stone powder is separately attached to the body, the attached abrasive layer is easy to fall off during use, resulting in poor durability and a considerably short service life.

In addition, as exemplified in Laid-Open Patent Publication No. 10-2005-0073739, there is a configuration in which protruding pieces for polishing are integrally formed by corroding one surface of the stick-shaped body.

However, in the case of this conventional configuration, durability is relatively excellent because it is integral, but since the top of the protruding piece is formed horizontally and polishing occurs at the horizontal end, the contact force with the nail surface is large and the resistance when cutting the nail is also Because of its size, a relatively large force must be applied in order to grind and polish nails, which makes it difficult to polish, and since a lot of dust is generated due to cutting, the surroundings are dirty due to scattering dust, which is inconvenient.

In addition, conventional abrasive files have a flat shape, so there is a problem in trimming half-moon-shaped nails, and since the polishing surface is straight, not only the nails but also the skin under the nails are damaged when used by the elderly.

Moreover, such a conventional file for polishing nails has a problem in that even if the nails are trimmed several times, the half-moon-shaped nails cannot be minimally and smoothly trimmed.

Therefore, there is an urgent need to develop a file for polishing nails that is convenient to use because it is easy to trim nails and can trim nails without effort.

Therefore, the first object of the present invention for solving the above problems is that a non-slip protrusion is formed on the handle of a nail trimming file so that it does not slip out of the hand, and an arc-shaped polishing tool is formed on one side and a date is formed on the other side. It is to provide a file for nail polishing that can be easily used by the elderly as the process of trimming nails is easy and can be trimmed without effort because the polishing tool is formed in the shape of a square.

The second purpose is that both ends of the abrasive tool are equipped with dead skin removal blades, so that hardened skin tissue around the nail can easily remove dead skin cells, and the roughness of both sides of the abrasive tool is different so that nails can be trimmed softer and smoother. In providing an abrasive file,

The third object is to provide a nail polishing file that is easy to manufacture due to its simple structure and is convenient and safe to use.

The present invention for achieving the above object is a handle having a non-slip projection formed on the outer circumferential surface in a cylindrical shape; and an arc polishing tool connected to one side of the handle and having a straight line shape in the longitudinal direction and having polishing pieces formed on upper and lower surfaces, respectively, wherein the arc polishing tool has an arc-shaped curved surface.

At this time, the bottom polishing piece is formed with an inclination from the handle side to the end of the arc polishing tool, based on the upper polishing piece, and preferably has a downward or upward inclination from the handle side to the end of the arc grinding tool.

In addition, the width of the arc of the polishing piece may widen or narrow as it proceeds from the handle side to the distal end of the arc polishing tool.

In addition, it is preferable that the curvature of the arc of the lower polishing piece is set to be different from each other in correspondence to the width of the arc of the lower polishing piece.

On the other hand, it is connected to the other side of the handle, has a straight line shape in the longitudinal direction, and arc polishing tools each formed with polishing pieces on the upper and lower surfaces; may further include.

In addition, it is connected to the other side of the handle, and has a straight square piece shape, and a piece polishing tool having polishing pieces formed on upper and lower surfaces, respectively; may further include.

Here, a keratin removal blade having an inclined surface for removing keratin around the nail may be formed at the distal end of the abrasive piece.

At this time, the roughness of the abrasive piece may be different from each other.

According to the configuration of the present invention as described above, an anti-slip protrusion is formed on the handle of the nail file to prevent slipping from the hand, and an arc-shaped grinding tool is formed on one side and a straight-edged square piece-shaped grinding tool on the other side. Since it is formed, the nail trimming process is easy and can be trimmed without effort, so the elderly can use it easily.

In addition, since dead skin removal blades are provided at both ends of the polishing tool, it is possible to easily remove dead skin tissue, which is hardened skin tissue around the nail, and the roughness of both sides of the polishing tool is different, so that the nail can be trimmed more softly and smoothly. .

Furthermore, it is a very useful invention that has a simple structure, is easy to manufacture, and is convenient and safe to use.

The file for polishing nails according to the present invention includes a handle 100 having a cylindrical shape and having non-slip protrusions 110 formed on an outer circumferential surface thereof; and an arc polishing tool 300 connected to one side of the handle 100 and having a straight line shape in the longitudinal direction and having

abrasive pieces

310 and 320 on upper and lower surfaces, respectively. It has an arc-shaped curved surface.

Hereinafter, embodiments according to the present invention will be described with reference to the accompanying drawings. On the other hand, the same reference numerals will be assigned to the same components in different embodiments.

1 is a front perspective view showing a nail polishing file according to a first embodiment of the present invention, FIG. 2 is a rear perspective view showing a nail polishing file according to a first embodiment of the present invention, and FIG. It is a side cross-sectional view showing the file for polishing nails according to the first embodiment.

1 to 3, the nail polishing file according to the first embodiment of the present invention is composed of a handle 100, a piece polishing tool 200, and a arc polishing tool 300.

The handle 100 has a cylindrical shape, and anti-slip protrusions 110 are formed on the outer circumferential surface.

Since the non-slip protrusion 110 is formed on the handle 100, the file for polishing nails does not slip from the hand, so there is a safety advantage.

The piece polishing tool 200 is connected to one side of the handle 100, and

polishing pieces

210 and 220 are formed on the upper and lower surfaces in the shape of a straight square piece, respectively. Here, a keratin removal blade 230 having an inclined surface for removing keratin around the nail is formed at the distal end of the

abrasive pieces

210 and 220 .

The upper polishing piece 210 and the lower polishing piece 220 of the piece polishing tool 200 have different roughnesses. That is, the grit representing the degree of roughness is formed differently. The grit indicates the number of protrusions formed in an area within 1 inch horizontally and vertically, and the smaller the grit, the rougher it is.

As such, since the roughness of the polishing pieces on the upper and lower surfaces of the flat polishing tool is different, it has the advantage of being rough or soft and smooth depending on the state of the nail.

In addition, a keratin removal blade 230 is provided at the end of the piece abrasive 200 and the end of the arc abrasive 300 to be described later, respectively, so that keratin, which is hardened skin tissue around the nail, can be easily removed. have.

The arc polishing tool 300 is connected to the other side of the handle 100, has a curved surface with an arc-shaped longitudinal section in a straight line in the longitudinal direction, and

polishing pieces

310 and 320 are formed on the upper and lower surfaces, respectively. Here, a keratin removal blade 330 having an inclined surface for removing keratin around the nail is formed at the distal end of the

abrasive pieces

310 and 320 . At this time, the keratin removal blade 330 may have an inclined surface formed at the same angle as or a different angle from the inclined surface of the keratin removal blade 230 .

Meanwhile, both sides of the

abrasive pieces

210, 220, 310, and 320 may be formed to be inclined with respect to the long axis, and thus, the shape of the cross section cut in the direction of the short axis may be formed in a trapezoidal or isosceles trapezoidal shape. At this time, the inclination angles of both sides may be the same or different.

The upper polishing piece 310 and the lower polishing piece 320 of the arc polishing tool 300 may have different roughnesses.

The arc abrasive tool 300 is for easily trimming the shape of a half-moon shaped nail, and the arc abrasive tool 300 serves to protect nails and skin and protect nails.

In the nail polishing file according to the embodiment of the present invention, after holding the handle with a finger, the nail is first reciprocated from side to side on the rough abrasive piece of the flat abrasive tool or the arc polishing tool, and then moved to another grinding tool. It can be polished by moving from this small coarse abrasive piece to a large grit abrasive piece.

Therefore, in the file for polishing nails according to the configuration of the present invention, an arc-shaped polishing ball is formed on one side and a straight square piece-shaped polishing ball is formed on the other side, so that the nail polishing process is easy and effortless. It has the advantage of being easy to use even for the elderly because it can be trimmed, and as shown in the drawing, the structure is simple and easy to manufacture. .

4 is a front perspective view showing a file for polishing nails according to a second embodiment of the present invention.

Referring to FIG. 4 , the nail polishing file according to the second embodiment of the present invention has the piece polishing tool 200 removed, compared to the nail polishing file of the first embodiment, and thus the handle 100 and It is composed only of the arc polishing tool 300.

In this way, the file for polishing nails of the present invention may be composed of the handle 100 and the arc polishing tool 300, and the handle 100 may be further extended in the longitudinal direction to facilitate the user's grip. Here, since the arc polishing tool 300 is the same as the arc polishing tool 300 of the first embodiment, a detailed description thereof will be omitted.

On the other hand, the lower polishing piece 320 of the arc polishing tool 300 presented in the first and second embodiments is based on the upper polishing piece 310 to correspond to the nail shape and nail size of each user. Thus, the abrasive piece 320 may be formed to have an inclination in the longitudinal direction, and the width and curvature of the arc may be formed differently. This will be described in detail with reference to FIGS. 5 and 6 .

5 is, as an example, a cross-sectional view taken along A-A' and B-B' of FIG. 1, and FIG. 6 is a cross-sectional view taken along A-A' and B-B' of FIG. 1 as another example.

5 and 6, the lower polishing piece 320 may be formed with an inclination from the handle 100 side to the distal end of the arc polishing tool 300 based on the upper surface polishing piece 310, and the handle ( 100), a downward slope (FIG. 5) or an upward slope (FIG. 6) may be formed toward the distal end of the arc polishing tool 300. Meanwhile, for comparison, FIG. 3 shows a case where the upper polishing piece 310 and the lower polishing piece 320 are horizontal.

In addition, as the lower polishing piece 320 progresses from the handle 100 side to the distal end of the arc polishing tool 300, the arc width W may widen or narrow. 5 is a case in which the width (W1>W2) of the arc becomes narrower as it proceeds from the handle 100 side to the distal end of the arc polishing tool 300. That is, in this case, it is easy to trim the nail of the thumb on the side of the handle 100, and it is easy to trim the nail of the little finger at the distal end of the arc polishing tool 300. Conversely, in FIG. 6 , the width of the arc (W3 < W4) widens as it proceeds from the handle 100 side to the distal end of the arc polishing tool 300. That is, in this case, the little finger nail is easily trimmed on the side of the handle 100, and the thumb nail is easily trimmed at the distal end of the arc polishing tool 300.

Meanwhile, it is preferable to set the curvature R of the arc differently in correspondence to the width W of the arc. That is, it is preferable that the setting relationship between the arc width W and the curvature R corresponds to the correlation between the human nail size and the curvature. Corresponding to the manufacture of the nail file of the present invention, the curvatures of R1, R2, R3 and R4 may all be different from each other.

On the other hand, as shown in FIGS. 1, 5 and 6, the cross-sectional width of the end of the arc polishing tool 300 may be narrower than the cross-sectional width of the handle side.

In this way, the bottom abrasive piece 320 is formed in a groove shape in the longitudinal direction, so that it can easily correspond to the half-moon shaped nail and easily trim the upper surface and distal end of the nail.

Meanwhile, in the present embodiment, a case in which one arc polishing tool 300 is formed has been described, but the arc polishing tool 300 may be formed on both sides of the handle 100. At this time, the arc polishing tools formed on both sides may be configured by combining different curvatures, slopes, arc widths, and roughnesses.

The file for polishing nails of the present invention can be easily used as an accessory for hairdressing.
