Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a nail clipper that can cut nails smoothly.

0002

[Conventional technology]

In conventional nail clippers, the front ends of the upper and lower pushing plates are bent inward. A cutting blade is provided on this edge so that they face each other, and the rear ends of both plates are connected to form a press operation plate. This is to apply pressure. This cutting blade is shaped like an arc concave inward when viewed from a flat surface. It is designed to make it easier to cut the fingernails that extend in a semicircular arc shape, but when cutting, The cutting line between the upper and lower blades that touch is straight in the horizontal direction.

0003 However, when viewed from above, the tip of the nail has a semicircular shape in the horizontal direction, but the fingernail When viewed from the head, it curves downward along the upper surface of the fingertip and also forms an arc in the vertical direction. Nail clippers usually cut from the top and bottom, so the surface to be cut is from the top and bottom. It becomes an arc shape in the direction. Therefore, as shown in Fig. 6, the surface to be cut has an arcuate claw (P) horizontally in the vertical direction. The range in which the arc-shaped claw can be linearly deformed when cut along the straight cutting line (C) in the direction can only be cut. Moreover, the parts on both sides of the nail can be cut in one operation. Since it deforms and cuts in a straight line, the cut surface is not smooth and the toes are cut evenly. There was the trouble of having to cut it multiple times to remove it. In addition, both ends (S) of the tip of the nail are particularly curved downward and penetrate into the finger flesh. To cut this part, insert one cutting blade between the finger flesh and the nail. The problem was that it was extremely difficult to cut.

0004

[Problem that the idea aims to solve]

This design does not linearly deform both sides of the nail at the cutting part when cutting the nail. It can be cut according to the arc of the cut surface of the nail, so both sides of the tip of the nail can be cut. It is possible to easily cut the edges, resulting in a smooth cut surface and a wide cutting range. The purpose is to obtain a nail clipper with a large circumference.

[0005]

[Means to solve the problem]

The proposed nail clipper is a pressing operation plate that presses an upper pressing plate and a lower pressing plate whose rear ends are connected. A nail clipper, which has arcuate cutting blades recessed inwardly and facing each other at the front ends of both plates. In the container, the upper blade of the upper pressing plate is formed into an arc shape concave upward from both ends of the pressing plate, Correspondingly, the lower blade of the lower press plate is formed into an arc shape that bulges upward from both ends of the press plate. This is what I did.

[0006]

[Effect]

When the upper and lower blades are pressed to cut, the cutting line is in the shape of an arc in the horizontal direction of the tip of the nail. It also follows the vertical arc of the surface of the nail to be cut, so both sides of the nail to be cut are The section is not linearly deformed, but is cut in an almost arc-shaped state. For this reason, the nail The cut surface, especially the cut surfaces on both sides of the cut part, will be smooth, and the area of one cut will be reduced. growing.

[0007] In addition, the lower blades near both ends of the lower press plate have a lower blade height, so You can easily insert the lower blade of this part under the parts on both sides of the tip of the claw. Because of this, it is possible to smoothly cut this part of the nail that was previously difficult to cut.

[0008]

【Example】

FIG. 1 shows a perspective view of an embodiment of the proposed nail clipper, in which 1 is an upper push plate, 2 is an upper push plate, and 2 is a The lower press plate, 3 is a connection part at the rear end of both press plates, 4 is a rotatable support shaft, and the upper press plate 1 and the lower An upper blade 5 and a lower blade 6 are provided at the front end of the pressing plate 2, facing each other. above this The blade 5 and the lower blade 6 have an arc concave and curved inward when viewed from the plane as shown in the plan view of FIG. It is formed in a shape and is made to match the horizontal arc shape of the tip of the claw (P) when viewed from the plane. However, this configuration is the same as the conventional one (see FIG. 5).

[0009] What should be noted in this case is that, as seen in the front view of FIG. The lower blade 6 is curved upward from both ends of the lower pressing plate 1, and the lower blade 6 is curved upward from both ends of the lower pressing plate 1. It is formed in an arc shape that bulges upward from both sides of the plate 2 and curves when the two blades touch. The cutting line (B) must match the vertical arc of the surface to be cut of the claw (P). It is.

0010 For this reason, when the upper blade 5 and lower blade 6 are pressed to cut, the cutting line (A) is of the nail. Along with the horizontal arc shape of the tip, the cutting line (B) is in the vertical direction of the surface to be cut of the nail. Because it follows the arc shape of It will be disconnected in this state. For this reason, the cut surface of the nail, especially the cut on both sides of the cut part, The surface becomes smoother and the range of one cutting can be increased.

[0011] In addition, the lower blade 6 near both ends of the lower press plate 2 has a lower blade height. Therefore, the lower blade 6 of this part can be easily inserted under the parts on both sides of the tip of the claw. This allows you to cut the nails in this area smoothly.

0012 FIG. 4 shows a practical example in which the push operation plate 7 can be freely stored in the recess 8 on the surface of the upper push plate 1. An example is shown. In this embodiment, a longitudinal recess 8 is formed on the surface of the upper press plate 1. The upper end of the rotatable support shaft 4 provided therein is prevented from protruding upward from this recessed portion 8. One end of the pressing operation plate 7 is pivotally attached to the head of this support shaft 4 with a pin 9, and rotated within the recessed part 8. The other end of the pressing operation plate 7 is provided with a claw piece 10 for triggering. be.

[0013] This pressing operation plate 7 is raised by a claw piece 10 when in use, and is aligned with the support shaft 4 in a straight line. Stand it up so that it stands up, rotate it 180 degrees, and move the lever part to the front side of the upper press plate 1 as before. The upper push plate 1 is pressed down by bringing it into contact with a surface. Also, when not in use, It can be stored in the recessed part 8 by reversing the operation described above, so it does not work like a conventional nail clipper. The pressing operation plate 7 does not protrude from the surface of the upper pressing plate 1, thus reducing the overall thickness of the nail clipper. This has the advantage of reducing the amount of stress.

[0014]

[Effect of the idea]

As mentioned above, according to the present proposal, the inwardly recessed arc-shaped front ends of the upper and lower pressing plates are The cutting blade further includes an upper blade of the upper pressing plate formed into an arc shape concave upward from both ends thereof; Correspondingly, the lower blade of the lower push plate is formed into an arc shape that bulges upward from both ends. When cutting, the cutting lines of the upper and lower blades are aligned with the horizontal arc of the tip of the nail and the vertical direction of the object to be cut. Since it follows the arc shape of the surface, the nail can be cut while keeping it in almost the arc shape. It cuts smoothly and can widen the cutting range, which was previously difficult to cut. This has the effect of making it possible to cut both ends of the tip of the claw very smoothly.
