TECHNICAL FIELD The present invention relates to a nail clipper that makes it easier to cut both sides of a nail.

[0002]

2. Description of the Related Art Although a nail clipper used in the past has a slight modification, basically, as shown in FIGS. 1 to 3, basically, a tip portion of a nail is provided in a gap between a pair of blade portions E, E. The blades E and E are pressed against the claws from both sides to cut the blades. The structure will be described below. A pair of blades E, E, which are formed in a concave arc shape on the outside so as to fit the curve of the tip of the claw, and whose longitudinal section is formed into an L-shaped hook, are made to face each other, and the blades E, E are usually Are separated from each other, and they are connected to the tips of the two vertically sandwichable clamping pieces 1a and 1b so that the nails can be brought close to each other when cutting and the cutting force can be applied to the nails. The bases of the two sandwiching pieces 1a and 1b are fixed to each other.

Reference numeral 2 is a lever piece that presses the free end portion of the base side clamping piece 1a, that is, the base of the blade portion E so as to elastically deform the clamping pieces 1a and 1b in the vertical direction. At the base end, a pressing portion 2b that pivotally supports a horizontal pin Q that is passed in the left-right direction is coupled to the tip protruding portion of a vertical pin P with a head that is passed vertically from the tip of the moving-side sandwiching piece 1b. It In use, the tip of the claw 9 is inserted into the gap between the blades E, E, the base side clamping piece 1a and the arm 2a are clamped with fingers, the arm 2a is pushed with the thumb, and the lateral pin Q is pressed. Is rotated about the fulcrum so as to come close to the moving side clamping piece 1b, and when the free end of the moving side clamping piece 1b is strongly pressed by the projection of the pressing portion 2b by the principle of leverage, the free end portions of both clamping pieces 1a, 1b Deform so that they approach each other, and the blades E, E approach each other, cutting the nail.

In the above-mentioned conventional nail clippers, since the blade portions E, E are erected at the tips of the sandwiching pieces 1, 1, respectively, the center of the sandwiching pieces 1a, 1b is perpendicular to the cut portion of the nail. It is necessary to match the line Y-Y, the angle between the finger and the nail clipper must be changed significantly (close to 180 degrees) at both corners of the nail 9, and the nail clipper must be changed in the middle. There is a problem that people who are handicapped cannot cut it well.

[0005]

The problem to be solved by the invention is that the above-mentioned conventional nail cutting hits the nail cutting because the blade portions E, E are erected at the free ends of the holding pieces 1a, 1b, respectively. However, the angle between the finger and the nail clipper must be greatly changed at both corners of the nail, which is difficult for children and handicapped people.The present invention solves the above problems. It also provides a nail clipper that can easily and easily cut nails for children and people with handicap.

[0006]

According to the present invention, as shown in FIG. 4 to FIG. 7, a tip portion of a pawl 9 is inserted into a gap between a pair of blade portions F, F so that the blade portions F, F are claw 9 from both sides. It is a nail clipper that is configured to be pressed and cut on a blade, and a tangent line T at a midpoint K of an arc-shaped curve C which is concave outside the blade portions F and F is inclined with respect to a longitudinal centerline Y-Y. It was made.

According to the present invention, for example, when cutting the right corner of the nail 9 on the left hand, the arc-shaped curve C of the blade portion F is cut off on the right side of the nail 9, and the center of the nail 9 is then cut, then the left corner. By changing the angle between the finger and the nail clipper, and changing the angle between the finger and the nail clipper by up to 90 to 120 degrees, the range of changing the angle between the finger and the nail clipper is small, and children and hands are inconvenient. Even people who are not good at it can cut it well. In addition, when cutting the nail 9 of the right hand, the nail clipper may be turned upside down.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a nail clipper according to the present invention, which is configured to insert a tip of a claw into a gap between a pair of blades, press the blades against the claws from both sides, and cut the claw, FIG. To explain with reference to FIG. 7, 1a and 1b are holding pieces of the nail clippers which are long in one direction and are opposed to each other, and the base side is integrally fixed, but the free end side is slightly separated in the vertical direction. The blades F, F are connected to each other with a slight gap so that the claw 9 can be inserted into the free end. Further, the blade portions F, F are normally separated from each other, but when the claws 9 are cut, they are brought close to each other so that the cutting pieces 1a, 1b are elastically moved in the vertical direction so that the cutting force can be applied to the claws 9. It can be transformed into.

Explaining each of the blade portions F, the shape of the tip thereof is formed in an outwardly concave arc shape, and the tangent line T at the midpoint K of the arc-shaped curve C is the longitudinal centerline YY. On the other hand, it is inclined (for example, 45 degrees), and one of the corners of the tip of the nail clipper is shaved off. The vertical cross section of each blade F is formed in an L-shaped hook.

The pressing member 2 that presses the free end portion of the moving-side holding piece 1b, that is, the root of the blade portion F so as to elastically deform the holding pieces 1a and 1b and brings the free end portions closer to each other will be described. Is a long arm portion in one direction, 2b is a holding portion connected to the tip of the arm portion 2a, and the tip protruding portion of the vertical pin P with a head that passes vertically from the free end portion of the base side clamping piece 1b. It is axially supported by a horizontal pin Q that extends in the left-right direction.

The operation is performed as follows. That is, the front end of the claw 9 is inserted into the gap between the blade portions F, F, the base side clamping piece 1a and the leverage piece 2a are sandwiched between the thumb and the other finger, and the arm portion 2a is pushed by the thumb to move sideways. When the pin Q is rotated about the fulcrum so as to come close to the base of the moving-side clamping piece 1b, the protrusion of the pressing portion 2b strongly pushes the tip of the base of the moving-side clamping piece 1b due to the principle of leverage, thereby moving the pin. The free end of the side holding piece 1b is deformed so as to approach the free end of the base side holding piece 1a, the blades F, F approach, and the claw 9 is cut.

At the time of this cutting, as shown in FIG. 6, when cutting the right corner of the nail 9 on the left hand, the arc-shaped curve C of the blade portion F is cut to the right side of the nail 6, and the nail 9 is left as it is. You can cut the nail 9 by changing the angle between the center and left corner and the finger and the nail clipper, and changing it by 90 to 110 degrees at the maximum. It is not necessary, and even children and people with handicap can cut it well. When cutting the nail 9 of the right hand, the nail clipper is turned over and used as shown in FIG.

[0013]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, the range in which the angle between the finger and the nail clipper is changed is small, and it is not necessary to change hands, and children and handicapped people can use it without difficulty. You can cut it.
