Abstract

PURPOSE:To polish the cut end of the nail to an arc shape by using sandpaper which has the arc shape and is stuck to grooves provided in a stationary plate. CONSTITUTION:A user holds the right and left edges of the stationary plate 1 with the thumb and forefinger, etc., of his one hand, places the nail of one finger of the opposite hand already cut by a nail cutter or scissors to a sand paper 2 and polishes the nail by moving the finger up and down. The user places the nail on the upper side of a larger radius of curvature if the size of the finger is larger and on the lower side of a smaller radius of curvature if the size is smaller at this time. The edge of the nail is formed a beautiful curve when the user moves the furrier vertically. The nail is polished to a glossy state if the nail is placed on the sandpaper 3 of finer grains and is similarly polished after the end of polishing with the sandpaper 2 of coarser grains. Urethane foam layers are stuck to the rear surfaces of the sandpaper 2, 3 and snugly fit to the curvature at the edge of the mail. These layers are helpful for rounding the edge of the nail by eliminating the angles at its front and rear surfaces. The generated debris of the nail falls and accumulates into a debris box 6 from an aperture 7. This box 6 is disengageable and the powder in the box is discarded into a dustbin.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sandpaper in which a nail clipper cut with a nail clipper or scissors has a clean arc shape and is smoothly polished.

[0002]

2. Description of the Related Art When a nail of a limb is cut with a nail clipper or scissors, its cut edge is hard to be a clean arc that conforms to the shape of a finger, and the cut surface is sharp. There are many things. Therefore, the metal file attached to the nail clipper is used for polishing, but the file's eyes are rough, and the file is often caught and hard to polish.

[0003]

SUMMARY OF THE INVENTION According to the present invention, the cut end of a nail cut with a nail clipper or the like is shaped into a clean arc shape, and
The object is to obtain a device using sandpaper that can be polished smoothly, comfortably, and easily.

[0004]

[Means for Solving the Problems] Applying a nail by using sandpaper which is stuck to a fixed plate having a cylindrical groove and made into a cylindrical shape, or stuck on a urethane foam stuck on a flat fixed plate. For example, the above problem is solved by using sandpaper that deforms in an arc shape according to the shape of the nail.

Embodiment FIG. 1 is a plan view of a nail polishing device embodying the present invention. FIG. 2 is a front view thereof. FIG. 3 is a cross sectional view thereof. FIG. 4 is a vertical cross-sectional left side view. FIG. 5 is a front view of the sandpaper 2 with urethane foam that is flatly stretched. FIG. 6 is an enlarged transverse sectional view thereof. 1 is a cylindrical surface (conical surface) with a larger radius of curvature toward the top
A fixing plate made of plastic or the like having two grooves. Two
Has a slightly larger grain size (400-
Cylindrical sandpaper with a urethane foam layer and a pressure-sensitive adhesive layer on the back surface using abrasive grains of No. 800). 3 is a sandpaper with a small abrasive grain (about 800 to 1200) fitted in the groove on the right, which has almost the same structure. Numerals 4 and 5 are extension plates at the left and right lower ends of the fixed plate 1. Reference numeral 6 is a shavings powder box sandwiched between them. There are no left and right walls, and an opening 7 is opened in the upper wall.

Although not shown, there are small protrusions on the left and right surfaces of the lower wall of the box 6, which fit into the recesses of the plates 4 and 5. The back surface of the sandpaper 2 is provided with a urethane foam layer 8 having a thickness of about 1 mm, and the back surface thereof is provided with an adhesive layer 9 and is adhered to the fixing plate 1. When using this device, hold the left and right edges of the fixed plate 1 with the thumb and forefinger of one hand, and touch the sandpaper 2 with one fingernail of the other hand that has already been cut with nail clippers or scissors. Move to and brush your nails.

At that time, if the finger is thick, the finger has a large radius of curvature, and if the finger is thin, the finger has a small radius of curvature. You can do it. After finishing sanding with the sandpaper 2, the sandpaper 3 can be rubbed with nails to polish the sandpaper 3 in a glossy state.

In these cases, the back surfaces of the sandpapers 2 and 3 are provided with a urethane foam layer, which is well adapted to the curvature of the edges of the nails, and the front and back surfaces of the nails have their corners rounded and polished. Useful for raising. (If the sandpaper is a non-deformable surface, the angle cannot be removed unless the angle at which the nail is applied is changed.) The resulting shavings of the nail fall and accumulate in the shavings receiving box 6 through the opening 7. If it is stored in the box to some extent, holding the fixing plate 1 in one hand and pulling the box 6 downward with the other hand, the two will come off and the powder in the box can be thrown into the trash box.

When the sandpapers 2 and 3 are reduced in abrasive grains, they are replaced with spare sandpapers. that time,
Since the lower end of the groove of the fixing plate 1 is slightly shorter than the length of the sandpaper, the lower end of the sandpaper can be pinched and the adhesive can be peeled off with the box 6 removed from the fixing plate 1. The spare sandpaper is the same as in Fig. 5.
A few cm in length and width, the back side of the urethane foam layer 8 and the pressure-sensitive adhesive layer 9 on the back side of the pressure-sensitive adhesive layer is attached with paraffin-impregnated paper, and the paper is peeled off and fitted into the groove.

A container for storing about 10 pieces of spare sandpaper may be attached to the lower portion of the box 6 or the like.
The sandpaper with the urethane foam layer and the adhesive layer on the back side can be used for polishing objects other than nails. However, sandpaper having no urethane foam layer or pressure-sensitive adhesive layer may be fitted into the groove of the fixing plate 1 for use.

The box 6 may be in the shape of a rectangular parallelepiped with only the top open, covered with a substantially flat lid, and the fixing plate 1 may be mounted on the lid.
Although the opening 7 is provided in the lid to drop the shavings, if the lid and the fixed plate 1 are also reversed in the front-rear direction to be housed in the box 6, the projection inside the box closes the opening 7 and the powder inside the box is removed. Try to prevent going out.

It is also possible to make a hole in the rear surface of the fixed plate 1, insert a match stick, and poke sandpaper from the fixed plate 1 so that it can be removed. The sandpaper 2 may be fitted in the groove on the front surface of the fixed plate 1 and the sandpaper 3 may be fitted in the groove on the rear surface. In the simplest case of the present invention, 1
The sandpaper 2 or 3 is attached to one fixing plate having one groove.

The material of the fixing plate may be hard plastic, foamed resin, wood, metal, cardboard, paper impregnated with plastic, a laminate of these, or the like. The shape of the cross section of the fixed plate is also the one with a cylindrical groove on the front surface of the flat plate, the arc-shaped one (sandpaper is closely attached to those grooves), and the U-shaped one (sand on the front end of the plate). Glue the left and right edges of the paper to make a gap between them).

A groove having a large number of arcuate cross sections having different radii of curvature may be provided on the front surface of the fixing plate 1 to polish finger nails having different thicknesses, or the left side of one groove may have a radius of curvature. The radius of curvature may be smaller and the radius of curvature may be larger toward the right, and the angle at which the finger is applied may be changed so that the fingernail of any thickness can be polished. There are various methods of making things with sandpaper attached to a fixed plate with grooves, width 2.3c
Pass a continuous cardboard belt of m through the adhesive liquid, sprinkle abrasive grains on one side, pass through a roller with a groove-shaped depression in the periphery and a roller with a ridge of a shape corresponding to it,
Molded into a cylindrical shape, cut and made, or extruded molten plastic from a nozzle with an arc-shaped cross section, sprinkle abrasive grains on the concave surface, cooled, cut and made, length × width 50
50 × 26 mm sandpaper is overlaid on a × 30 mm aluminum plate, sandwiched by a mold, and the whole is made into a cylindrical surface,
In addition, folding the left and right edges of the aluminum plate, sandwiching sandpaper to make it, vertical × horizontal × depth is 2 × 5 × 5
Depth 4 cm in the heating mold having a depression of about cm
Put the abrasive grains to a certain degree and heat it, put the plastic plate on it, press it from above with a mold having a cylindrical groove on the lower surface, deform the plastic plate into a cylindrical shape, and put the abrasive particles on the lower surface. You may make it adhere and make it. (Many vertical vents are opened in the upper mold, exhaust from the top with an exhaust pump, suck up plastic pieces after pressurization, pull up with the upper mold, carry to multiple parts, small vents Insulate and drop the plastic piece into two pieces, one with a low melting point on the bottom and one with a high melting point on the top.

A long sandpaper belt is fed into the heated air with the back side facing upwards, sprinkled with microcapsules as a raw material for styrofoam, foamed, and a cylindrical roller in the upper part and a roller whose peripheral surface in the lower part bulges in an arc shape. It is also possible to obtain a flat article having the abrasive grain surface recessed in the shape of a groove and the upper surface flattened. Sandpaper may be attached to the aluminum piece and sandwiched between the molds to be deformed into a cylindrical surface.

A nail polisher may be constructed by sticking a flexible urethane foam layer having a thickness of about 2.3 mm on a flat fixing plate and further sticking sand cloth or sand paper using soft paper on it. . In that case, if the nail is applied, the sand cloth is deformed into an arc according to the shape of the nail, and the cut end of the nail can be smoothly polished. Vertical x horizontal is 3
If you stick a sand cloth on a flat fixing plate with a through hole or box-shaped recess of about 5 cm and put your finger on the sand cloth on the hole, the sand cloth will be deformed into an arc according to the shape of the nail. You may A small hole may be opened in this sand cloth to allow the shavings to fall into the recess provided below.

At this time, the longitudinal length of the sand cloth may be made slightly shorter than the vertical length of the hole, and only the left and right edges of the sand cloth may be attached to the fixing plate so that the shavings fall into the hole from the upper and lower gaps. Make a cut or perforation on a 5 cm wide cardboard, plastic belt, etc., apply adhesive to the surface, sprinkle abrasive grains, wind it up to a cylinder with a diameter of about 2 cm, tear it off along the cut etc. Good.
