Description

[Detailed description of the invention] The present invention relates to a nail clipper.

Conventionally, nail clipping was mostly done manually, by using a lever with a 1000-degree angle to push the nail between the upper and lower blades, or by sharpening it with a small knife held in the hand. etc. were done and n was done.

If you do it manually, for example, if you cut your finger,
It was not easy for right-handed people to cut their fingernails on their right hand, and for left-handed people, it was not easy to cut their fingernails on their left hand, leading to problems such as accidentally cutting too deep or damaging the skin.

In the (1) grinding 141] device that rotates the grinding member by the movement of the moat, the claw is brought into contact with the rotating grinding member, so the pressing force of the claw is determined by the strength of the force. The amount of incision of the nail is different from V, and the first time I tried to make it look like Taniuchi.]
It is difficult to make chestnuts ((it sinks, and if you do, you can feel the heat around your nails get wet).

For this reason, the disadvantage is that the degree of risk is actually greater than that of manual methods.

The purpose of this invention is to eliminate the above-mentioned drawbacks by completely increasing safety so as not to cause deep nails or injuring the skin, and by making it easy to cut.

In this invention, a slit is provided in the wall of the case, a claw is inserted into the slit, and the claw protruding from s#J of the wall having the slit is cut by a movable grinding member of the movable blade. Our goal is to provide cutting tools.

Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In the figure, 1 is a case, and a wall 2 of the case 1 has a slit (2) in which a nail is inserted.

In addition, inside the case 1, the wall 2 is inserted through the slit 3.
A movable cutting member 4 is provided for cutting the entire claw protruding from the back surface.

The above-mentioned movable cutting member 4 is provided with a disk 6 that rotates together with a vertical drive shaft 5 in the case of figures M2 and M3.
7 blades arranged radially on the surface of the 0-
) V 6'f is provided, and the blade 7 is placed at the required interval 1d around this roll 60? ]l- As shown in the figure m5, a pair of left and right pulleys 8 which are directly connected to the drive shaft are driven from the drive shaft via an appropriate transmission device, and this goo 9
8, an endless belt 9 having a blade 7 on its surface is stretched between them, or a disk 60 surface is used instead of the blade r, although not shown in the figure.
Polishing sheet (sandpaper) on the low/l/6' surface
In addition to passing an exchangeable endless polishing sheet tray between the pulleys 8 and 9, the polishing member may be reciprocated by an appropriate method, or As shown in FIG. 2, the cutting member 4 may be reciprocated parallel to the wall 2 along the slit 3 together with the drive shaft.

In addition, the above-mentioned blade R has a straight line or a curved line that sequentially displaces the nine positions of the blade plate to weaken the resistance to the nail being cut, and allows the nail to be cut completely without difficulty. There are some placements of H with respect to the claw, such as parallel to the claw, perpendicular to the claw, or intersecting the claw at an angle other than one angle.

In addition, the above roll 6' is placed on the surface of one row/l/6+.
By providing rough cutting, finishing cutting, and polishing blades in order from one end to the other, rough cutting can be performed in the polishing trench.

The width of the slit 3 (tζ) is slightly larger than the thickness of the nail, but it is desirable that the nail can fit in as tightly as possible.

The number of the slits 3 may be one, or as shown in the figure, a large number of slits may be arranged in parallel so that a nail can easily fit into the slit.

At this time, if you make the widths of the slits different, you can insert a thick brush such as a thumb into the wide slit 3, and insert a thin claw metal such as a little finger into the narrow slit 8, so that the nail can be inserted into the slit 8. Shake can be minimized.

Moreover, although the slit 3 is a straight line in the illustrated case, it may be a curved line that follows the curve of the nail.

The above-mentioned drive l111iI6 uses the output shaft of a motor (not shown) built into the gripping cylinder 10, and is powered by a replaceable battery, a home electric light line, etc. As a power source, switch 1
The motor is started to operate after one meeting.

Generally speaking, the case 1 is fitted into the cylinder 10 or screwed into the cylinder 10 (in the case shown, the entire annular groove 12 is provided on the inner peripheral surface of the opening of the case 1, and the groove 12 is provided on the outer peripheral surface of the tip of the cylinder 10). The annular ring 13 is fitted into the ring (name).
Since it is removable, the case 1 can be completely removed and disposed of to remove the noise of the nails from cutting inside the case 1.

In addition, by making the case 1 entirely of metal or synthetic resin that can be bent under pressure, the wall 2 can be easily bent with a fingertip.
By applying pressure to the cutting member 4 and bringing it closer to the back surface of the wall 2, the nail can be cut as short as possible.

At this time, when the cutting member 4 is used as the bell in Fig. S, the tip of the claw indents the part of the belt corresponding to the claw marked with "-".

This can be done by cutting smoothly along the roundness of the nail. be able to.

Note that by making the wall 2 as thin as possible and keeping the cutting member 4 close to the back surface of the wall 2, the nail can be cut short.

In addition, as shown in FIG.
is provided, the case 1 can be moved up and down by loosening or tightening the fastener 15 passed through the long hole 14, and
By increasing or decreasing the distance between the wall 2 and the cutting member 4 (the entire amount of movement of the case 1 is determined by the scale 16), the degree of protrusion of the claw can be freely adjusted.

Furthermore, as shown in Fig. 7, one roll-shaped cut Pf
A blade 7 is used from one end of the lJ member 4 to the middle, and a reed is used as a file or other polishing surface 11 from the middle), a blade τ is placed on one side of two parallel rolls, and an abrasive sheet or file is placed on the other side. IJ ff1o' (illustration omitted) If you provide a purple blade or #T polishing ■τ on the belt 9 as described above, the blade γ
It is possible to perform cutting with a brush and then polish the cutting edge of the nail with the polishing surface 17, or to select only cutting or polishing.

In addition, in addition to the above, two (two threads) or more than two (two threads) may be rough ground on both ends of the slit 3, or between both ends.
A cutting member (not shown) for performing double-edge grinding may be arranged, and the position where the claws are inserted may be sequentially displaced.

Further, the wall 2 having the slit 3 may have an arc, a dog-shaped convex surface, or a concave surface, instead of being flat as shown.

In the case of the above-mentioned convex surface, the slippage and rocking motion of the finger that occurs when cutting a nail with a small width such as the little finger, and in the case of a convex surface, the sliding motion of the finger that occurs when cutting a nail with a large width such as the thumb. and rocking motion become easier.

The nail clipper according to the present invention has the above-mentioned configuration, and the entire nail cutting method will be explained below. First, switch 11 is turned on and the motor is operated by the main power source, and then the cutting section After sliding it, insert your nail into slit 3,
The claws extending into the slits 8 and projecting into the cake 1 are cut by the movable cutting member 4.

As described above, according to the nail cutter according to the present invention, the nails are inserted into the slits of the case, and the movable cutting member inside the case cuts the nails with the brush that is loaded into the case. Deep nail polishing 9 eliminates the problem of damaging the skin near the nail, and even a clumsy person can easily and quickly cut the nail.

Furthermore, when a cutting member is constructed by combining a nail, a polishing member, and a tray, it is possible to first cut the nail and then polish the cutting edge of the nail.

Furthermore, depending on the degree of insertion of the nail, the brush may be left for a long time,
Nails can be cut short.
