Description

  The present invention is used as one of the components of a nail clipper, presses a pair of blades in the nail clipper against their elastic force, and cuts the nail by bringing the blade edges of each blade close to each other This relates to the lever for cutting.

  As a nail clipper that cuts off a surplus portion of the nail and adjusts the length and shape of the nail, for example, there are those described in Patent Document 1 and Patent Document 2. These nail cutters are operated and operated to press the pair of blades against their elastic force, and the blades of the blades are brought close to each other to cut the nail.

  Further, in the nail clipper described in Patent Document 1, a finger rest is provided at this end portion by operation, and a file portion that is curved in a concave shape so as to form a part of a spherical surface is provided in the finger rest. Yes. This file part exhibits the function of grinding the nail to adjust the shape and the anti-slip function of suppressing the sliding of the finger with respect to the finger contact part when the operating lever is operated.

  Further, in the nail clipper described in Patent Document 2, the file portion is formed flat.

  However, in the nail clipper described in Patent Document 1, when the user operates the lever to remove the nail, the abdomen of the finger is pressed against the file part, but depending on the size of the finger There is a possibility that the abdomen cannot be sunk down to the bottom of the filed part that dents into a spherical shape. In this case, the contact surface with the file portion of the abdomen of the finger is not sufficiently wide, and the file portion cannot sufficiently exhibit the anti-slip function.

  On the other hand, in the nail clipper described in Patent Document 2, since the file portion is flat, the abdomen of the finger can be brought into contact with the file portion, while the surface where the file portion is in contact with the abdomen is formed. Originally narrow. This is because the abdomen of the finger is curved in a convex shape along the length direction and along the width direction, whereas the file portion is flat. Therefore, also in this case, there is a problem that the file portion cannot sufficiently exhibit the anti-slip function as in the case of Patent Document 1.

  In addition, as an aspect of pressing the abdomen of the finger against the file part, an aspect of pressing the abdomen of the finger against the file part so that the length direction of the finger matches the width direction of the finger contact part, and There is a mode in which the width direction is pressed against the file portion so as to match the width direction of the finger rest portion. Whether the file portion is recessed in a spherical shape or a flat shape, the above-described problem can occur even when the abdomen of the finger is pressed against the file portion in any manner described above.

  The present invention has been made in view of such circumstances, and its purpose is to make it possible to bring the file portion into contact with the abdomen of the finger on a wide surface regardless of the size of the finger, and to provide a non-slip function. An object of the present invention is to provide an operation lever for nail clippers that can be sufficiently exerted.

  The nail clipper operating lever that solves the above-mentioned problems is used for nail clippers that are connected to each other at the base end portion and that has a pair of blade portions that have blade edges at their respective tips, and is provided on a part of itself. A nail-cutting lever that presses the both blades against their elastic force to bring the blades close to each other and excise the nail by the operation through A file portion that is curved in a concave shape only along the length direction of the finger rest portion is provided.

  According to the above configuration, in the nail clipper operating lever, the file portion has a function of grinding the nail to adjust the shape, and when the operating lever is operated to cut off the surplus portion of the nail, The function to suppress slipping (slip prevention function) is demonstrated.

When causing the file portion to exhibit the anti-slip function, the abdomen of the finger is pressed against the file portion. Fine irregularities on the surface of the file portion are brought into contact with the abdomen of the finger, and the abdomen is prevented from slipping.
Here, the abdomen of the finger is curved in a convex shape both along the length direction and along the width direction. On the other hand, the file portion is curved along the length direction of the finger rest portion, but is not curved along the width direction. The file part is open | released by the both sides about the width direction of a finger rest part. There are no particular obstacles on both sides of the file that prevent contact with the abdomen. Therefore, unlike the case where the file portion is recessed in a spherical shape, the file portion makes contact with the abdomen of the finger at a wide portion including the bottom of the file portion and makes the finger difficult to slip regardless of the size of the finger. This effect is achieved even when the abdomen of the finger is brought into contact with the file part so that the length direction of the finger matches the width direction of the finger pad part. It can also be obtained when it is brought into contact with the file so as to match the above.

  Further, since the file portion is curved only along the length direction of the finger rest portion, it comes into contact with the convex curved portion of the abdomen of the finger. For example, when the abdomen of the finger is pressed against the file part in such a manner that its length direction matches the width direction of the finger pad part, the curved part along the length direction of the file part is about the abdomen of the finger It touches the curved part along the width direction. In addition, when the abdomen of the finger is brought into contact with the file part in such a manner that the width direction of the finger matches the width direction of the finger pad part, the curved part along the length direction of the file part is long with respect to the abdomen of the finger. It touches the curved part along the vertical direction. Therefore, in any of the above cases, the file portion comes into contact with the abdomen of the finger on a wider surface than when formed in a flat shape, thereby making it difficult for the finger to slip.

In the nail clipper operating lever, it is preferable that the file portion is formed of a member different from the finger contact portion and is fixed to the finger contact portion.
According to said structure, a file part consists of a member different from a finger rest part. From this, compared with the case where the file portion is formed by directly processing the finger contact portion, there are more options for the material of the file portion, and from these options, a more suitable material for the file portion can be selected. It becomes possible. In addition, the types of files and options for processing methods increase.

  Similarly, there are more choices for the material of the finger pad (operating lever for nail clipper), and it is possible to select a more suitable material and processing method for the finger pad (operator lever for nail clipper) from these options. As a result, the degree of freedom of design and design increases.

  In the nail clipper operating lever, the finger rest portion is provided with a concave curved surface that curves concavely only along the length direction of the finger rest portion, and the file portion is formed on the concave curved surface. It is preferably formed by a plate-like body that is curved and joined along.

  According to said structure, what was formed by the plate-shaped body which is a member different from a finger rest part as a file part is used. The plate-like body is bent along the concave curved surface provided in the finger pad and joined to the concave curved surface. At this time, since the concave curved surface is curved only in one direction (the length direction of the finger contact portion), in the concave curved surface, the depth changes in the length direction of the finger contact portion, but the width direction The depth does not change. Therefore, unlike the case where the finger resting portion is recessed in a spherical shape, it is only necessary to bend the plate-like body separate from the finger resting portion only in one direction (the length direction of the finger resting portion). It is possible to follow the surface.

  According to the nail clipper operation lever, the file portion can be brought into contact with the abdomen of the finger on a wide surface regardless of the size of the finger, and the anti-slip function can be sufficiently exhibited.

Hereinafter, one embodiment of the nail clipper operation will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the main part of the nail clipper of this embodiment is constituted by a nail clipper main body 10. The nail clipper main body 10 includes a pair of blades and a nail clipper operating lever (hereinafter simply referred to as “operation lever”) 14, similarly to a general nail clipper. Next, each part which comprises the nail clipper main body 10 is demonstrated.

<A pair of blades>
Here, in order to distinguish a pair of blade parts, what is located on each upper side in FIGS. 1 and 2 is referred to as an upper blade part 11, and what is located on each lower side is referred to as a lower blade part 12.

  The upper blade portion 11 and the lower blade portion 12 are each composed of a pair of plate materials that are formed in a long shape from metal. The upper blade portion 11 and the lower blade portion 12 are connected to each other by being fixed to each other at their base end portions (the right end portion in FIG. 2). Blade tips 11A and 12A are formed at the tips of the upper blade portion 11 and the lower blade portion 12 (left end in FIG. 2) in a state of facing each other. In the upper blade portion 11 and the lower blade portion 12, a support shaft 13 having a head portion 13A at one end (the lower end in FIG. 2) is directed from the lower blade portion 12 toward the upper blade portion 11 in the vicinity of the blade edges 11A and 12A. Is inserted. The head 13 </ b> A of the support shaft 13 is locked to the lower blade portion 12 from the lower side, and the upper end portion of the support shaft 13 protrudes upward from the upper blade portion 11. A notch 13 </ b> B is formed in the upper portion of the support shaft 13. The support shaft 13 is rotatable about its axis (not shown).

<Operation lever 14>
As shown in FIGS. 1 and 4, the operating lever 14 has a long shape like the upper blade portion 11 and the lower blade portion 12, and is disposed on the upper side of the upper blade portion 11. In the operation lever 14, unlike the upper blade portion 11 and the lower blade portion 12, the one end portion (the left end portion in FIG. 4) is the base end portion, and the other end portion (the right end portion in FIG. 4) is the tip portion. Has been. A pair of arm portions 14 </ b> A that are spaced apart from each other in the width direction (vertical direction in FIG. 4) of the operating lever 14 is formed at the base end portion of the operating lever 14. Between the two arm portions 14A, the upper portion of the support shaft 13 is inserted and disposed. Further, a pin 15 is inserted into the both arm portions 14A in the width direction of the lever 14, and the pin 15 is locked to a notch portion 13B (see FIGS. 2 and 3) of the support shaft 13. .

Instead of the notch 13B, a support hole may be formed in the radial direction of the support shaft 13, and the pin 15 may be inserted into the both arm portions 14A and the support hole.
One side (upper side in FIG. 2) of the long operating lever 14 in the thickness direction (up and down direction in FIG. 2) is the front surface 14B, and the other side (lower side in FIG. 2) is the back side 14C. ing. As shown in FIG. 2, when the nail clipper is not used, the operating lever 14 is overlaid on the upper blade portion 11 and the back surface 14C is concealed so as to face the upper blade portion 11 (hereinafter referred to as “unused”). It is called a use state). Further, as shown in FIGS. 1 and 3, the operating lever 14 has an upper blade as it moves away from the base end while taking a posture in which the back surface 14C is on the upper side and the front surface 14B is on the lower side when using the nail clippers. It is made into the state (henceforth a usable state) inclined so that it may distance from the part 11 upwards. Note that the switching between the non-use state and the usable state is performed by rotating the operation lever 14 around the support shaft 13 and the pin 15 to be reversed.

  On the back surface 14C of the operating lever 14, a step surface 14D having a constant depth from the back surface 14C is formed in a region from the vicinity of the arm portion 14A to the vicinity of the central portion in the length direction of the operating lever 14. The first file portion 16 is provided here. The first file portion 16 is formed of a member different from the operation lever 14. Here, the first file portion 16 is formed using a metal plate 17 having a uniform thickness. On one surface of the plate-like body 17 (the lower surface in FIG. 2), a file formed by regularly arranging a large number of minute recesses is engraved by machining. And the said plate-shaped body 17 is affixed on the said level | step difference surface 14D with the adhesive agent in the surface (upper surface of FIG. 2) on the opposite side to a file.

  In the operation lever 14, a finger contact portion 14E is integrally formed in a region from a position slightly away from the step surface 14D toward the tip side to the tip of the operation lever 14. The finger rest 14E is a place where a finger (usually the thumb F) is pressed when the operating lever 14 is operated. The finger contact portion 14E is formed with a concave curved surface 14F that is curved concavely only along the length direction thereof. The depth of the concave curved surface 14F from the back surface 14C is deepest in the central portion in the length direction of the finger pad 14E, and gradually becomes shallower as the distance from the central portion increases. The depth of the concave curved surface 14F from the back surface 14C is the same (does not change) in the width direction of the finger pad 14E.

  The concave curved surface 14F is provided with a second file portion 18 over substantially the entire area thereof. The second file portion 18 is a portion corresponding to the file portion in the scope of the utility model registration request, and is formed of a member different from the finger pad portion 14E. Here, the second file portion 18 is formed using a plate-like body 19. The plate-like body 19 is formed of a blade material, so-called blade steel, which is flat and has a uniform thickness. On one surface (the lower surface in FIG. 2) of the plate-like body 19, a file formed by regularly arranging a large number of minute recesses is engraved by machining (see FIG. 4).

  The plate-like body 19 is curved along the concave curved surface 14F of the finger pad 14E. That is, the plate-like body 19 is curved in a concave shape only along the length direction of the finger pad 14E. And the said plate-shaped body 19 is affixed on the said concave curved surface 14F with the adhesive agent in the surface (upper surface of FIG. 2) on the opposite side to a file. As described above, the second file portion 18 is configured by the plate-like body 19 in which the filed eyes are formed and curved along the concave curved surface 14F and joined to the finger pad portion 14E. The second file portion 18 is deepest in the central portion with respect to the length direction of the finger rest portion 14E, gradually becomes shallower as it is away from the central portion, and is the same in the width direction of the finger rest portion 14E. It is concavely curved so as to be deep. A file formed on one surface of the plate-like body 19 is also curved in a similar concave shape.

The nail clipper of the present embodiment includes a nail scattering prevention case 20 in addition to the nail clipper main body 10.
<Nail scattering prevention case 20>
The nail scattering prevention case 20 is for preventing the cut off excess nail pieces from scattering, and the side wall that surrounds the upper blade portion 11 and the lower blade portion 12 except for the blade edges 11A and 12A. 20A and the bottom wall part 20B which is located under the lower blade part 12, and was connected to the said side wall part 20A. The nail scattering prevention case 20 is attached to the upper blade portion 11 and the lower blade portion 12 so as to be slidable in the length direction thereof. By this sliding, both ends of the upper blade portion 11 and the lower blade portion 12 in the width direction are opened, and the nail pieces in the nail scattering prevention case 20 are discharged from these open portions. Is possible.

The nail clipper is configured as described above. Next, the action of this nail clipper will be described focusing on the action of the operating lever 14.
In the operation lever 14, the first file portion 16 exhibits a function of grinding the nail and adjusting the shape. In addition to the function of the nail being ground and adjusting the shape, the second file portion 18 is similar to the first file portion 16, and the finger rest when the operation lever 14 is operated to cut off the surplus portion of the nail. A function to prevent the thumb F from sliding with respect to 14E (anti-slip function) is exhibited.

  Even when any one of the first file portion 16 and the second file portion 18 is used, the nail clipper in the non-use state is switched to the usable state. At the time of this switching, the operating lever 14 in the unused nail clipper shown in FIG. 2 is rotated about the support shaft 13 and the pin 15 and reversed. In the usable state shown in FIGS. 1 and 3, the operating lever 14 moves away from the upper blade portion 11 as it moves away from the base end portion while adopting a posture in which the back surface 14C is on the upper side and the front surface 14B is on the lower side. It will be in the state which inclined like this.

Subsequently, the file portion is applied to the outer edge portion of the nail to be ground, and the nail and the file portion are relatively moved. By the relative movement in the contact state, the outer edge portion of the nail is ground.
Here, the first file portion 16 is not curved and has a flat shape, whereas the second file portion 18 is curved in a concave shape. As described above, since the first file portion 16 and the second file portion 18 have different forms, the user can select a file portion that is more suitable for grinding.

The anti-slip function of the second file portion 18 is exhibited when the surplus portion of the nail is excised using a nail clipper.
That is, when the nail is excised, the nail clipper is gripped by the thumb F and the index finger (not shown). At the time of gripping, the thumb F is brought into contact with the second file portion 18 and the index finger is brought into contact with the proximal end portion of the nail scattering prevention case 20.

There are the following two modes for bringing the thumb F into contact with the second file portion 18.
Mode 1: As shown in FIGS. 3 and 4, the abdomen F1 of the thumb F is brought into contact with the second file portion 18 so that the length direction thereof matches the width direction of the finger rest 14E.

Aspect 2: As shown in FIGS. 5 and 6, the abdomen F1 of the thumb F is brought into contact with the second file portion 18 so that the width direction thereof matches the width direction of the finger rest part 14E.
Here, the abdomen F1 of the thumb F is curved in a convex shape both along the length direction and along the width direction. On the other hand, the second file portion 18 is curved along the length direction of the finger pad portion 14E, but is not curved along the width direction. 4 and 6, the second file portion 18 is opened at both side portions 18S in the width direction of the finger rest portion 14E, as indicated by a thick dashed-dotted frame. None of the two side portions 18S of the second file portion 18 obstructs contact with the abdomen F1. Therefore, unlike the patent document 1 in which the file portion is recessed in a spherical shape, the second file portion 18 has an abdominal portion F1 of the thumb F in a wide portion including the bottom of the second file portion 18 regardless of the size of the thumb F. To make the thumb F less slippery. This effect is also obtained when the abdomen F1 of the thumb F is brought into contact with the second file portion 18 in any of the above aspects 1 and 2.

  Moreover, since the 2nd file part 18 is curving only along the length direction of the finger pad part 14E, it contacts the convex curved part of the abdominal part F1. For example, as shown in FIGS. 3 and 4, when the abdomen F1 of the thumb F is pressed against the finger rest 14E in the first mode, the second file portion 18 is about the abdomen F1 of the thumb F. It contacts a portion curved in a convex shape along the width direction. As shown in FIGS. 5 and 6, when the abdomen F1 of the thumb F is pressed against the finger rest 14E in the second mode, the second file 18 is about the abdomen F1 of the thumb F. It contacts a curved portion that is convex along the length direction. Therefore, in any of the above aspects, the second file portion 18 comes into contact with the abdominal portion F1 of the thumb F on a surface wider than that of Patent Document 2 formed in a flat shape, and makes the thumb F difficult to slip.

  Even when the abdomen F1 of the thumb F is brought into contact with the second file portion 18 in any of the above modes, the surplus portion of the nail is positioned between the blade edges 11A and 12A, and the distance between the thumb F and the index finger is increased. It is narrowed. A pressing force is applied to the finger contact portion 14E through the second file portion 18, and the operating lever 14 is tilted downward (to the lower blade portion 12 side) with the pin 15 as a fulcrum in both arm portions 14A. The tilting operation lever 14 presses the upper blade portion 11 and the lower blade portion 12 against their elastic force. Both the blade edges 11A and 12A are brought close to each other, and the surplus portion of the nail is excised. The removed nail piece is accommodated in the nail scattering prevention case 20.

According to the embodiment described in detail above, the following effects can be obtained.
(1) The finger rest 14E of the operating lever 14 is provided with a second file portion 18 that is curved in a concave shape only along its length direction (FIGS. 1 and 3).

  Therefore, not only can the nail be ground with the second file portion 18, but also the thumb F can be prevented from sliding with respect to the finger rest portion 14E when the operation lever 14 is operated to cut off the surplus portion of the nail. it can.

  Further, an effect that cannot be obtained with a spherically recessed file portion, that is, the second file portion 18 is brought into contact with the abdominal portion F1 of the thumb F that curves in a convex manner regardless of the size of the thumb F (see FIG. Fit). Further, the second file portion 18 can be brought into contact with the abdomen F1 of the thumb F on a surface wider than the flat file portion. As a result, unlike the file portion recessed in a spherical shape or the flat file portion, the anti-slip function can be sufficiently exerted, and the usability can be improved.

  In the above-described effect, the nail clipper user brings the abdomen F1 of the thumb F into contact with the second file 18 so that the length direction thereof matches the width direction of the finger pad 14E (FIG. 3, FIG. Also in FIG. 4), an aspect 2 (FIGS. 5 and 6) in which the abdomen F1 of the thumb F is brought into contact with the second file portion 18 so that the width direction thereof coincides with the width direction of the finger rest 14E is obtained.

Furthermore, the nail clipper user can select which mode is used to bring the thumb F into contact with the finger pad 14E.
(2) The 2nd file part 18 is formed with the member different from the finger pad part 14E, and is being fixed to the finger pad part 14E (FIG. 1, FIG. 3).

  Therefore, compared with the case where the second file part 18 is formed by directly processing the finger rest part 14E, the material options for the second file part 18 are increased. From these options, the second file part 18 is more suitable. A suitable material can be selected. In addition, there are more choices of file types and processing methods.

  Similarly, the choice of the material of the finger rest 14E (operating lever 14) increases, and from these options, a more suitable material and processing method for the finger rest 14E (operating lever 14) can be selected. Therefore, the degree of freedom of design and design can be increased.

  (3) The finger contact portion 14E is provided with a concave curved surface 14F that curves in a concave shape only along its length direction. The second file portion 18 is formed by a plate-like body 19 that is curved and joined along the concave curved surface 14F (FIG. 3).

  For this reason, the second file portion 18 is formed of a plate-like body 19 which is a member different from the finger pad portion 14E. The plate-like body 19 has a concave shape provided in the finger pad portion 14E. It is curved along the curved surface 14F and joined to the concave curved surface 14F. At this time, since the concave curved surface 14F is curved only in one direction (the length direction of the finger contact portion 14E), the depth of the concave curved surface 14F changes in the length direction of the finger contact portion 14E. However, the depth does not change in the width direction. Therefore, unlike Patent Document 1 in which the finger pad portion 14E is recessed in a spherical shape, the plate-like body 19 separate from the finger pad portion 14E is curved only in one direction (the length direction of the finger pad portion 14E). The plate-like body 19 can be easily along the concave curved surface 14F simply by making it.

(4) In addition to the first file portion 16 having a planar shape, a second file portion 18 curved in a concave shape is provided (FIGS. 1 and 3).
Therefore, if you want to grind the nail with a flat file part, use the first file part 16, and if you want to grind the nail with a concavely curved file part, use the second file part 18. You can use different parts. The user of the nail clipper can grind the nail in a desired manner, and in this respect, the usability of the nail clipper can be improved.

(5) When a file portion is formed on a curved surface that is recessed in a spherical shape in Patent Document 1, a filed portion is engraved on the curved surface by an electric discharge machine or an NC machine, but this leads to an increase in manufacturing cost.
In this respect, in the present embodiment, the flat metal plate-like body 19 is processed in advance and curved along the concave curved surface 14F of the finger pad portion 14E, and then pasted with an adhesive. . Processing on a flat surface is easier than processing on a curved surface. Therefore, the second file portion 18 can be easily formed.

Further, in the present embodiment, a file can be machined without using an electric discharge machine or an NC machine, and an increase in manufacturing cost can be suppressed.
Note that it is difficult to curve a flat plate-like body along a curved surface that is recessed in a spherical shape, and thus it is difficult to realize this structure.

  (6) When forming a file part by sticking a member different from the finger contact part 14E to the finger contact part 14E, it is also conceivable to use sandpaper (paper file) as the member. However, sandpaper has a problem in terms of durability, and it is necessary to re-apply it many times.

In this regard, in the present embodiment, the metal plate 19 is used, and the second file portion 18 is formed by processing a file on this.
Therefore, the durability can be improved as compared with the case where the second file portion 18 is formed using sandpaper, and it is not necessary to perform replacement for a long period of time.

In addition, the said embodiment can also be implemented as a modification which changed this as follows.
<About a pair of blades>
-A pair of blade part (upper blade part 11, lower blade part 12) may be comprised by the single board | plate material which makes long shape. In this case, a double plate portion (upper blade portion 11 and lower blade portion 12) is formed by folding a single plate material at the central portion.

<About finger rest 14E>
The finger rest 14E is not limited to extending along the length direction of the operation lever 14, but may be inclined with respect to the length direction of the operation lever 14, as shown in FIG. Also in this case, the finger rest 14E is provided with the second file portion 18 that is curved concavely only along the length direction thereof.

In FIG. 7, elements similar to those described in the above embodiment are denoted with the same reference numerals.
-The finger contact part 14E in the operation lever 14 may be formed in the length different from the said embodiment. An example is shown in FIG. In FIG. 8, on the back surface 14C of the operating lever 14, a finger contact portion 14E is provided in a wide area from the tip portion to the vicinity of the center portion in the length direction of the operating lever 14. Also in this case, the finger rest 14E is provided with the second file portion 18 that is curved concavely only along the length direction thereof.

In FIG. 8, the same reference numerals are given to the same elements as those described in the above embodiment.
The finger rest 14E may be provided at a position closer to the base end side than the distal end portion of the operation lever 14 on condition that the finger contact portion 14E is a part of the operation lever 14.

  -Although not shown in figure, the operation lever 14 may be divided | segmented into the main-body part and the finger | toe contact part 14E. And the operation lever 14 may be comprised by the finger rest part 14E being fixed to a main-body part. Further, the operating lever 14 may be configured by connecting the finger pad 14E to the main body so as to be bent in the width direction of the finger pad 14E.
