However, in the nipper-type nail clippers disclosed in Patent Documents 1 and 2, the blade for cutting the nail is formed in a linear shape, and the grip portion ( grip part) is stretched.
For this reason, the straight edge of the blade is applied to the tip of the nail with a rounded contour to cut the nail. It is very inconvenient and there is also a safety problem such as deep nails.

In addition, when cutting toenails, it is particularly difficult to change the direction of the toes, and the hand gripping the handle of the nail clipper must be moved along the contour of the nail. Therefore, when cutting the toenails on the tip of the toes or when cutting the toenails on the side opposite to the dominant arm, bend the wrist with the arm extended and point the tip of the nail clipper toward you. The problem remains that it is necessary to take an unnatural posture, which is very inconvenient. Such postures and movements are very difficult for people who have difficulty bending forward, such as the elderly, people with back pain, pregnant women, and obese people. problem remains.

Specifically, blade portions 100a and 100b are formed as shown in FIGS. 2(b) and 2(c), respectively.

As shown in FIG. 2(c), the blade portion 100a(b) formed on the blade body 101a(b) extends from the substantially center of the blade portion 100a(b) in the length direction of the blade body 101a(b). It is curved (curved) so that the vertical distance to the horizontal line passing through the center of the opening is relatively shorter than the vertical distance from the edge region of the blade portion 100a (b) to the horizontal line passing through the center of the opening. shape). By forming the blade portion 100a(b) in such a shape, it becomes easier to fit the tip of the nail having a rounded contour, and it becomes possible to cut the nail more safely.

The internal space of the blade body (main body formed in the shape of a rectangular cylinder with a bottom) functions as a holding space for holding the clipped nail (see FIGS. 2(b) and 2(c)). This holding space can prevent the clipped nail from scattering.

Further, the blade 101a is held by the blade holder 102a, and the blade 101b is held by the blade holder 102b. The blade holding portion 102a is connected to a handle portion 104a, which is a portion that is gripped by a user who performs nail clipping, and is connected to the blade holding portion 102b and the handle portion 104b.

In this way, a nail clipping piece is formed by the blade body 101a(b) having the blade part 100a(b) of a predetermined length, the blade body holding part 102a(b), and the handle part 104a(b). The type nail clipper S is composed of these two (a pair of) nail clippers.
In the following description, when there is no need to distinguish between a and b in each component, the description may be omitted.

Each of the nail clippers is operated by contacting one blade body 101 (blade portion 100) with the other blade body 101 (blade portion 100) via the grip portion 104, or by one blade body 101 (blade portion 100). ) is rotatably supported by a support shaft 103 so that the other blade body 101 (blade portion 100) can be separated from the other blade body 101 (blade portion 100). The blade holder 102 holds the blades such that the openings of the internal spaces of the blades 101 face each other.

As already described, the blade 101a is held by the blade holder 102a, and the blade 101b is held by the blade holder 102b. For example, the blade 101 can be configured to be detachable from the blade holder 102 .
Specifically, for example, a convex portion is formed at a predetermined portion of the blade body 101, a concave portion is formed at a predetermined portion of the blade holding portion 102, and the convex portion and the concave portion are fitted together as a holding mechanism as shown in FIGS. 2 can be assembled into a nipper-type nail clipper S as shown in FIG.
As a result, when the sharpness of the nail clipper becomes dull, it is sufficient to replace the blade body, and the burden of maintenance costs can be reduced compared to buying a new nail clipper as a whole.

Further, when the convex portion of the blade body 101 and the concave portion of the blade body holding portion 102 are fitted together, the length direction of the blade portion 100 and the length direction of the grip portion 104 are substantially the same (not shown), or as shown in FIG. The blade 101 can also be held by the blade holder 102 so that they intersect at a predetermined angle as shown in a).
In this manner, the holding mechanism of the blade holding portion 102 is such that the blade holding portion 102 can rotate the length direction of the handle portion 104 and the length direction of the blade portion 100 at an arbitrary angle based on the length direction of the handle portion 104 . It functions as a mechanism for holding the blade body 101 so as to intersect at .
As a result, the user using the nipper type nail clipper S can arbitrarily determine the angle of the blade part 100 that makes it easy to cut the nail according to the user's posture when cutting the nail. It is possible to improve usability and improve safety during use.

The angle at which the convex portion of the blade 101 and the concave portion of the blade holding portion 102 are fitted is, for example, grooves on the outer surface of the convex portion of the blade 101 and the inner surface of the concave portion of the blade holding portion 102, respectively. By forming gear grooves (for example, gear grooves) and meshing the respective grooves, positioning may be possible while adjusting by a unit angle such as 5 (degrees) or 10 (degrees). This makes it possible to more easily determine the angle between the blade portion 100 and the handle portion 104 according to the user's body type and preference.

FIG. 3 is a 3D model diagram for explaining an example of the configuration of the blade body 101. As shown in FIG.
As shown in FIG. 3, for example, the outer surface of the blade body 101 may be processed using a smooth curve or chamfered. Also, the opening of the blade body 101 may be formed in a substantially elliptical shape. By performing such processing, the nipper-type nail clipper S can be used more safely, and the weight of the nipper-type nail clipper S can be reduced, so that the usability can be further improved. .

As described above, in the nipper-type nail clipper S according to this embodiment, the blade portion formed in the blade body 101 is formed to be curved, and a holding space is formed to hold the clipped nail. The angle with the portion 100 can be arbitrarily set.
