Description

Nail Clipper {Nail clipper}

The present invention relates to a nail clipper. More specifically, the present invention relates to a nail clipper, which is formed to have an upper and lower step similar to an actual nail having a shape of a cutting blade curved up and down, so that the nail can be easily trimmed.

In general, the nail clipper, as shown in Figure 1, the upper steel plate 11 and the lower steel plate 12 is formed in a shape in which one end is joined to each other, the other end is opened, the upper steel plate 11 and An upper straight cutting blade 16 and a lower straight cutting blade 18 are formed in each of the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17 of the lower steel sheet 12, and the upper steel sheet 11 and the lower portion. The steel plate 12 has a hole in which the pressing bar 13 penetrates and is fixed to the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17, and the lower portion of the pressing bar 13 has the lower portion thereof. It is fixed to the lower steel sheet front end portion 17 of the steel plate 12, the upper end portion is fixed to penetrate the upper steel sheet front end portion 15 of the upper steel plate 11 to be exposed thereon. A hole is formed at an upper end of the pressure bar 13, and is configured to rotatably fix the operation handle 14 to be interviewed with the upper steel plate 11. In addition, the operation handle 14 is formed so that the lever projection 19, which serves as a lever, to interview the upper surface of the upper steel plate (11). The operation principle by the configuration as described above is a common nail clipper can be easily understood by those skilled in the art as well as ordinary users. That is, the operating handle 14 is operated so that the lever projection 19 is interviewed on the upper steel plate 11, and the upper steel plate 11 and the lower steel sheet which are elastically coupled to each other by pressing. 12 is interlocked, and thus the upper straight cutting blade 16 and the lower straight cutting blade 18 formed at one end of each of the upper steel plate 11 and the lower steel plate 12 operate to trim the nail. Will be. Such nail clippers are manufactured and sold by leading domestic and foreign manufacturers, and anyone can easily purchase and use them. However, as shown in Fig. 2, the conventional nail clipper is actually formed with a straight cutting line for cutting the nail, and as shown in Fig. 3, it is curved only in the front-rear direction. The curved shape of the cutting blade in the front and rear direction has a curved shape when one nail is protruded from the edge toward the center when viewed from above, and thus the curved shape in the front and rear direction so that the nail can be easily trimmed. Has

However, when looking at the nail in detail, the nail has a three-dimensional shape of the curved shape in the vertical direction in addition to the curved shape in the front and rear directions. That is, as shown in FIG. 4, it has an up-down step also in the up-down direction as shown by the identification code t1. However, the conventional nail clipper ignores the upper and lower steps of the nail 22, and when viewed from the front as shown in FIG. 2, the cutting edge is formed only in a straight line, so that the nail 22 is not easily trimmed. In addition, there are inconveniences of having to perform several cutting operations, and also, the nail 22 is distorted until the upper straight cutting blade 16 and the lower straight cutting blade 18 are fully engaged when pressed for cutting. The force is deformed but not cut. If the fingernail 22 is cut by continuously operating the operation handle 14 here, there is a problem that a smooth cut surface is not formed. That is, since the nail 22 is cut in a distorted state, it is difficult to smooth the nail 22 smoothly and beautifully. Therefore, in order to trim the nails 22, the cutting operation must be repeated several times, and accordingly, there is a disadvantage in that the nails 22 are cut several times. In addition, when the nail 22 is cut several times in small portions, the cutting surface is not evenly formed, and if you want to smooth and evenly polish it, there may be a case that the nail 22 can only be trimmed deeper than originally intended. Excessive cutting of the nail 22 may be accompanied by pain due to severe exposure of the end of the weak finger 21 to the pain under the nail 22, and in severe cases, the nail 22 may be deformed enough to dig into the flesh and be operated. As a result, problems may need to be eliminated.

An object of the present invention has a top and bottom step similar to the actual nail having a shape of the cutting edge is curved up and down, and is formed to have a front and rear step like a conventional nail clipper is configured to easily trim the nail To provide.

The cutting blade of the nail clipper according to the present invention has an upper and lower step and a front and rear step with respect to the front end portions of the upper steel sheet front end and the lower steel front end of the upper steel plate and the lower steel plate, which form the main body of the nail clipper, respectively. The upper curved cutting blade and the lower curved cutting blade are curved in the vertical direction to have both, and curved in the front-rear direction.

In addition, the nail clipper according to the present invention is arranged up and down at a predetermined interval and a cutting blade for cutting the nail is formed at one end thereof, through-holes are formed in the adjacent side of the cutting blade, respectively, the other end is in close contact with each other Upper and lower steel plates; A pressure bar penetrating the through-holes of the upper and lower steel plates and having a lower end fixed to the lower steel plate; And an operating handle rotatably fixed to a hole formed at an upper end of the pressure bar and having a lever protrusion formed therein, wherein the upper steel sheet front end and the lower steel sheet are not closely bonded to the upper steel plate and the lower steel plate. Each of the front end portions is curved in an up and down direction so as to have both a top and bottom step and a front and rear step with respect to the front end parts, and also includes an upper curved cutting blade and a lower curved cutting blade in a forward and backward direction.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 5 to 7, the cutting blade of the nail clipper according to the present invention is arranged up and down at a predetermined interval and a cutting blade for cutting the nail 22 is formed at one end thereof, the adjacent side of the cutting blade A through hole is formed in each of the upper ends of the upper and lower steel plates 11 and 12 in close contact with each other; A pressure bar 13 penetrating through the through-holes of the upper steel plate 11 and the lower steel plate 12 and having a lower end thereof fixed to the lower steel plate 12; And an operating handle 14 rotatably fixed to a hole formed at an upper end of the pressure bar 13 and having a lever protrusion 19 formed therein, wherein the upper steel plate 11 and the lower steel plate Each of the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17 which are not closely bonded to each other in (12) is curved in the vertical direction so as to have both the upper and lower steps and the front and rear steps with respect to the front ends. It is characterized by consisting of the upper curved cutting blade 31 and the lower curved cutting blade (32).

In the above, cutting blades are arranged up and down at a predetermined interval and cut nails 22 at one end thereof, through-holes are formed at adjacent sides of the cutting blade, respectively, and upper ends of the upper ends of which are closely bonded to each other. 11 and lower steel plate 12; A pressure bar 13 penetrating through the through-holes of the upper steel plate 11 and the lower steel plate 12 and having a lower end thereof fixed to the lower steel plate 12; And an operating handle 14 rotatably fixed to a hole formed at an upper end of the pressure bar 13 and having a lever protrusion 19 formed therein. It can be easily understood. In other words, the cutting blade of the nail clipper according to the present invention is the upper steel plate 11 and the lower steel plate 12 is not in close contact with the upper steel sheet front end portion 15 and the lower steel sheet front end portion 17 for each of the front end portions. It is characterized by consisting of the upper curved cutting blade 31 and the lower curved cutting blade 32 is curved in the vertical direction so as to have both the upper and lower steps and the front and rear steps.

The upper curved cutting blade 31 and the lower curved cutting blade 32 formed on each of the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17 are as shown in FIGS. 6 and 7. Each of the upper steel sheet shearing portion 15 and the lower steel sheet shearing portion 17, which are not in close contact with the steel plate 11 and the lower steel sheet 12, is curved up and down to have both the upper and lower steps and the front and rear steps with respect to the front ends. In addition, it is made of a curved shape in the front and rear direction.

The upper and lower steps t3 of the upper curved cutting blade 31 and the lower curved cutting blade 32 have a height difference equal to or similar to the upper and lower steps t1 of the nail 22 to form a curved surface. do. That is, although there are individual differences, it is possible to have a height difference in the range of 1 to 5 mm, which is the same as or similar to the upper and lower steps t1 of the common nail 22 having a step of 1 to 5 mm, more preferably. Preferably, the height difference can be in the range of 2 to 4 mm. When the upper and lower step t3 is less than 1 mm, the height difference is too small, so that a cutting edge close to a straight line is formed, similar to a conventional nail clipper, so that the nail 22 may not be easily trimmed. When the height exceeds 5 mm, the height difference is so large that the nail 22 is cut in the deformed state by pressing the nail 22 before cutting the nail 22, so that the nail 22 cannot be easily trimmed. There may be a problem. In addition, the front and rear steps t4 of the upper curved cutting blade 31 and the lower curved cutting blade 32 are formed to have a front and rear step according to the size of the nail clipper itself, regardless of the shape and size of the nail 22. Preferably, it can be made to have a back and forth difference of the range of 0.5-2.5 mm. This may be determined in the same or similar range to the front and rear step t1 of the cutting edge of the conventional nail clipper. When the front and rear steps t4 of the upper curved cutting blade 31 and the lower curved cutting blade 32 are less than 0.5 mm, the step in the front and rear direction of the cutting blade is too small, so that a cutting edge close to a straight line is formed to form a nail ( 22) there may be a problem that can not be easily trimmed, if the contrary exceeds 2.5mm, there may be a problem that the front and rear difference is too large to easily trim the nail 22, too. The front and rear steps t4 of the upper curved cutting blade 31 and the lower curved cutting blade 32 may be formed to have the same or similar curvature as the front and rear steps t1 of the cutting blade of the conventional nail clipper. It will be apparent to those skilled in the art that this can be easily understood.

That is, the upper curved cutting blade 31 and the lower curved cutting blades 32 formed three-dimensionally so as to have an upper and lower step t3 and a front and rear step t4 as described above have a cut surface similar to the actual shape of the nail 22. Since the nail 22 is deformed and distorted as much as possible until just before the nail 22 is cut, the nail 22 cuts the upper curve cutting edge 31 and the lower curve cutting at the time of cutting the nail 22. It can be cut in the state interviewed the whole surface 32.

Therefore, when trimming the nail 22 using the nail clipper according to the present invention, the upper curve cutting blade 31 and the lower curve cutting three-dimensionally formed to have the upper and lower steps t3 and the front and rear steps t4. The blades 32 allow the nail 22 to be easily and smoothly trimmed in just one or two cutting operations.

Therefore, according to the present invention, the shape of the cutting blade has a top and bottom step similarly to the actual nail 22 having a curved shape up and down, and is formed to have a front and rear step like a conventional nail clipper to facilitate the nail 22. By providing a nail clipper configured to trim, there is an effect of making the nail 22 easy and smooth and beautifully trimmed.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
