Description

本考案は、人の爪先の余剰分を切断する爪切り器に関する。 The present invention relates to a nail clipper that cuts excess portions of a human toe.

通常、爪切り器は、二股状に連結された一対の弾性片からなり、各弾性片の先端に刃が形成してあり、その一対の刃、すなわち上刃と下刃が閉じることにより爪先を切断する構造である。この構造では、両刃先が突き合うので刃こぼれや摩耗をおこし易いし、深爪もおこし易い。これを解決するものとして特許文献１に示す構造のものが提案されている。その構造は、上刃と下刃のうち下刃が刃ではなくまな板状になっており、上刃とまな板との間で爪を切断する。この場合、まな板の先端を上刃から前方に１、２ｍｍ突き出した形状にし、切断に際してまな板の先端に指の腹を当ててストッパー作用を得ることにより爪の挿し込み長さを制限し、深爪を防止できるようにしたものである。 Usually, a nail clipper is composed of a pair of elastic pieces connected in a bifurcated shape, and a blade is formed at the tip of each elastic piece, and the pair of blades, that is, the upper blade and the lower blade are closed to close the toe. It is a structure to cut. In this structure, since both the blade edges are abutted, blade spills and wear are likely to occur, and deep claws are also likely to occur. As a solution to this problem, a structure shown in Patent Document 1 has been proposed. The structure is such that, of the upper blade and the lower blade, the lower blade is not a blade but a cutting plate shape, and the claw is cut between the upper blade and the cutting plate. In this case, the tip of the cutting board is shaped to protrude 1 mm forward from the upper blade, and when cutting, the length of the nail is limited by applying a stopper to the tip of the cutting board to obtain a stopper action. It can be prevented.

刃先を爪形状に合わせた複雑形状の場合、二股状弾性片と一体の切断刃では刃先の研磨を伴う製造が困難である。また、これまでに知られた爪切り器では切断刃の切っ先が爪先に侵入することがあり、これにより爪先に切り込みができたり、肉を切ったりすることがあった。この不都合は手足の不自由な老人やその介護者によっておこり易かった。 In the case of a complicated shape in which the blade tip is matched to the nail shape, it is difficult to manufacture the blade tip with a cutting blade integrated with the bifurcated elastic piece. Further, in the nail cutters known so far, the cutting edge of the cutting blade may invade the toe, which may cause the nail to cut or cut meat. This inconvenience was easily caused by elderly people with disabilities and their caregivers.

本考案の目的は、刃先の形状が製造性の障害になることを防止でき、及び刃先の寿命低下を防止でき、更に深爪や爪先の異常切り込みを防止でき、更に切断に際して爪に不快な押し拡げ力が加わることを防止できる爪切り器を提供することにある。 The purpose of the present invention is to prevent the shape of the cutting edge from becoming an obstacle to manufacturability, to prevent the life of the cutting edge from being shortened, to prevent abnormal cutting of deep nails and toes, and to uncomfortably spread the nails during cutting. It is providing the nail clipper which can prevent that force is added.

本考案の爪切り器は、凸曲面状の爪受け台を一端に形成した第１部材と、この第１部材に回動操作可能に支持されその回動操作により前記爪受け台に対して開閉動きをする一端部を有する第２部材とを備える。その第２部材とは別体に造られこの第２部材の前記一端部に取り付けられて前記爪受け台との間で爪を切断する切断刃板と、前記第１及び第２部材の双方間に設けられ前記切断刃板の刃先が前記爪受け台に接触またはその寸前で前記第２部材の閉成方向動きを止めるストッパー機構とを備える。 The nail clipper of the present invention has a first member formed with a convex curved nail cradle at one end, and is supported by the first member so as to be pivotable. A second member having one end that moves. A cutting blade plate that is formed separately from the second member and is attached to the one end of the second member and cuts the nail between the nail cradle and between the first and second members. And a stopper mechanism that stops the movement of the second member in the closing direction immediately before or in contact with the claw base.

前記切断刃板は、指先端の凸曲面に近似の湾曲状をなし、その刃先が前記爪受け台の凸曲面状に近似した曲線を描き、且つ前記爪受け台の前端から僅か後退した位置で爪に当たる位置関係をもち、切っ先が爪に侵入することを阻止する障害壁を前記第２部材の前記切断刃板の左右両端位置に設ける。 The cutting blade plate has a curved shape that approximates the convex curved surface of the finger tip, the cutting edge draws a curve that approximates the convex curved surface shape of the nail cradle, and is slightly retracted from the front end of the nail cradle. Obstacle walls that have a positional relationship to hit the nail and prevent the cutting edge from entering the nail are provided at the left and right end positions of the cutting blade plate of the second member.

切断刃板は、三次元に展開する複雑形状であっても第２部材とは別体部品であるから刃先の研磨加工を容易になし得る。爪受け台及び刃先が爪の曲面形状に近似しているので切断時に爪に不自然な力が加わらない。爪の刃先への侵入量が爪受け台の前端により制限され深爪を防止できる。爪に切断刃板の切っ先が侵入することを障害壁によって防止できる。 Even if the cutting blade plate has a complicated shape developed three-dimensionally, the cutting edge plate can be easily polished because it is a separate part from the second member. Since the nail cradle and the cutting edge approximate the curved shape of the nail, an unnatural force is not applied to the nail during cutting. The amount of nail penetration into the blade edge is limited by the front end of the nail cradle, thereby preventing deep nails. The obstacle wall can prevent the cutting blade plate from entering the nail.

以下、本考案の第１の実施例を図１〜図９を参照しながら説明する。この爪切り器は、短冊状の金属製の第１部材１と同じく金属製例えばアルミ製の第２部材２とを含み、この第２部材２は第１部材１に取り付けられた一対の支持板３に回動操作可能に支持してある。すなわち、この一対の支持板３を第１部材１にピン圧入等の方法で固定し、その支持板３間に支え軸４を橋渡しに固定し、この支え軸４を第２部材２に形成してある支持孔５（図２、図４）に貫通させてある。 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The nail clipper includes a strip-shaped metal first member 1 and a metal-made second member 2 made of aluminum, for example, and the second member 2 is a pair of support plates attached to the first member 1. 3 is supported so as to be rotatable. That is, the pair of support plates 3 are fixed to the first member 1 by a method such as pin press fitting, and the support shaft 4 is fixed to the bridge between the support plates 3. The support shaft 4 is formed on the second member 2. The support hole 5 (FIGS. 2 and 4) is penetrated.

この構造では、第１及び第２部材１、２の前端側（図２中左端側）が切断端側で、その後端側（図２中右端側）が握り部分であって、握り部分を上下に遠近操作することにより第２部材２が支え軸４を中心に回動し、切断端側が遠近、すなわち開閉動きをする。以後、爪切り器の側面を示した図２の状態を基準に上記の通り「前」「後」の位置表現をする。 In this structure, the front end side (left end side in FIG. 2) of the first and second members 1 and 2 is the cut end side, and the rear end side (right end side in FIG. 2) is the grip portion. The second member 2 is rotated about the support shaft 4 by performing the perspective operation, and the cutting end side is in the perspective, that is, opens and closes. Thereafter, the positions of “front” and “rear” are expressed as described above based on the state of FIG. 2 showing the side of the nail clipper.

前記両部材１、２間にスプリング６を配置しており、これによって切断端側に開き状態を保つ回動力を常時付与する。前記一対の支持板３は、図３に示すように第１部材１の切断端側から約１／３後方までに渡ってこの第１部材１を左右から挟む壁状をなし、爪飛散遮蔽壁を兼ねる一方、切断刃の支持作用を兼ねる。これら一対の支持板３の前端部分間に切断刃支持体７をピン圧入等の方法で固定してあり、その支持体７に切断刃板８が取り付けられる。 A spring 6 is disposed between the two members 1 and 2 so that a turning force that keeps the open state is always applied to the cut end side. As shown in FIG. 3, the pair of support plates 3 has a wall shape that sandwiches the first member 1 from the left and right from the cut end side of the first member 1 to the rear of about 1/3, and a nail scattering shielding wall. While also serving as a support for the cutting blade. A cutting blade support 7 is fixed by a method such as pin press-fitting between the front end portions of the pair of support plates 3, and the cutting blade plate 8 is attached to the support 7.

この切断刃板８は、図６に示すように前記第１部材１とは別体であって鋼板製であり、その刃先８ａが爪のアーチ形状に近似した曲線を描き、具体的には正面視上方に窪む湾曲線状なし、鋭利に研磨された後焼き入れされる。前記切断刃支持体７の正面側が切断刃取付け面７ａをなし、この面７ａは図１、図３、図４に示すように後方（握り部分方向）に窪む湾曲状、すなわち爪の望ましい切断曲線に近似した曲面に形成してあり、その刃取付け面７ａに沿うように前記切断刃板８（この段階では平板状）をその弾性力に抗して湾曲させながら密着させ、配置する。この取り付けに先んじて切断刃板８を図８に示すように刃先８ａの研磨後に予め湾曲成形しておいてもよい。研磨前に湾曲に塑性変形させておくと、刃先８ａが三次元の曲面（或いは曲線）を持つことになり、研磨加工が非常に困難になる。切断刃板８の切断刃支持体７への上記のような配置状態は、前記一対の支持板３の一部分を切断刃板８側にかしめる等により固定でき、また、切断刃板８の上方への滑り止めは、図２、図８から理解できるように、前記切断刃支持体７の切断刃取付け面７ａを僅か窪ませることで可能である。 As shown in FIG. 6, the cutting blade plate 8 is separate from the first member 1 and is made of a steel plate. The cutting edge 8a draws a curve that approximates the arch shape of the nail, specifically, the front surface. There is no curved line that is depressed upward, and it is quenched after being sharply polished. The front side of the cutting blade support 7 forms a cutting blade mounting surface 7a, and this surface 7a has a curved shape that is recessed backward (in the direction of the grip portion) as shown in FIGS. The cutting blade plate 8 (in this stage, a flat plate shape) is brought into close contact with the elastic force so as to be along the blade mounting surface 7a, and is placed in close contact with the blade mounting surface 7a. Prior to this attachment, the cutting blade plate 8 may be curved in advance after the cutting of the cutting edge 8a as shown in FIG. If it is plastically deformed into a curved shape before polishing, the cutting edge 8a has a three-dimensional curved surface (or curved line), which makes polishing very difficult. The above-described arrangement state of the cutting blade plate 8 on the cutting blade support 7 can be fixed by, for example, caulking a part of the pair of support plates 3 to the cutting blade plate 8 side. As can be understood from FIGS. 2 and 8, it is possible to prevent slippage by slightly denting the cutting blade mounting surface 7 a of the cutting blade support 7.

前記第２部材２の切断端側には爪受け台９を一体に形成してある。この爪受け台９の上面は、図１、図５、及び図８に示すように爪Ｍを乗せたときの爪先のアーチ形状に近似した凸曲面をなし、この爪受け台９と前記切断刃板８の刃先８ａとの間で爪Ｍを挟み切断するようになっている。すなわち、第１及び第２部材１、２の握り部分を閉じ方向に操作すると切断刃板８の刃先８ａと爪受け台９との間が閉じられ、刃を持たない爪受け台９がまな板、切断刃板８が包丁の役をなして爪Ｍを切断する。このとき、爪受け台９及び刃先８ａが爪先のアーチ形状に近似した曲面及び曲線をなすため、切断に際して爪に不快な押し広げ力が加わらない。 A claw base 9 is integrally formed on the cut end side of the second member 2. As shown in FIGS. 1, 5, and 8, the upper surface of the nail cradle 9 has a convex curved surface that approximates the arch shape of the nail when the nail M is placed, and the nail cradle 9 and the cutting blade The claw M is sandwiched and cut between the blade 8 and the blade edge 8a. That is, when the grip portions of the first and second members 1 and 2 are operated in the closing direction, the gap between the blade edge 8a of the cutting blade plate 8 and the claw cradle 9 is closed, and the claw cradle 9 having no blade is a cutting board, The cutting blade plate 8 serves as a knife and cuts the nail M. At this time, since the nail cradle 9 and the blade edge 8a form a curved surface and a curve that approximate the arch shape of the toe, uncomfortable pushing and spreading force is not applied to the nail during cutting.

切断時に刃先８ａが爪受け台９に強く当って刃こぼれや摩耗を早めないようにするためにストッパー機構を備える。このストッパー機構は、この実施例では、図２及び図４に示すように、一対の支持板３間に橋渡し固定した当接部材であるストッパーピン１０と、このストッパーピン１０が貫通するように前記第２部材２に形成したストッパー孔２ａとにより構成してある。図２、図５は、閉じ操作が行われて切断刃板８の刃先８ａが爪受け台９の上面に接触又はその寸前（爪の切断は可能）にストッパーピン１０がストッパー孔２ａの内面（ストッパー受け面）に当り、それ以上の閉じ操作を阻止した状態を示す。切断刃板８の取り付け位置は、図２、図４、図８に示すように、刃先８ａが爪受け台９の前端（左方端）より１，２ｍｍ後退した位置で爪Ｍに当る位置関係に定め、深爪を防いでいる。この爪受け台９の前端面すなわち正面９ａ（図１、図８）は、爪Ｍを爪受け台９に乗せた状態で指の腹部先端面と合致し易いように湾曲状をなす。 A stopper mechanism is provided in order to prevent the blade edge 8a from strongly hitting the claw cradle 9 during cutting so as to prevent blade spillage and wear. In this embodiment, as shown in FIGS. 2 and 4, the stopper mechanism includes a stopper pin 10 that is a contact member that is bridged and fixed between a pair of support plates 3, and the stopper pin 10 passes through the stopper pin 10. The stopper member 2 is formed in the second member 2. 2 and 5 show that the closing operation is performed so that the cutting edge 8a of the cutting blade plate 8 comes into contact with the upper surface of the claw receiving base 9 or is just before it (the claw can be cut). The stopper receiving surface) is shown in a state where further closing operation is prevented. As shown in FIGS. 2, 4 and 8, the cutting blade plate 8 is attached to the nail M at a position where the blade edge 8a is retracted by 1 mm from the front end (left end) of the nail receiving base 9 as shown in FIGS. To prevent deep nails. The front end surface of the nail cradle 9, that is, the front surface 9 a (FIGS. 1 and 8) is curved so that the nail M is placed on the nail cradle 9 so that it easily matches the tip of the abdomen of the finger.

前記一対の支持板３のうち、夫々の前方端部分を、切断刃板８から前方に延出させており、この延出部分が爪の異常切り込みを防止するための障害壁３ａの役割をなす。ここで、爪の異常切り込みとは、図９に示すような現象をいう。この図９は、上下一対の切断刃Ｎを持つ従来の爪切り器による異常切り込み状況を示しており、上下切断刃間にその切断刃Ｎの切っ先Ｎａから爪Ｍが縦向き、横向き又は斜め向きに侵入させた状態を示しており、このような状態で切断操作すると、爪先端に縦、横、或いは斜め方向の切り込みが発生し、爪先に裂け目ができたり、肉を切ったりする現象をいう。 Each front end portion of the pair of support plates 3 extends forward from the cutting blade plate 8, and this extended portion serves as an obstacle wall 3a for preventing abnormal claw cutting. . Here, the abnormal cut of the nail refers to a phenomenon as shown in FIG. FIG. 9 shows an abnormal cutting state by a conventional nail clipper having a pair of upper and lower cutting blades N, and the nail M is vertically, horizontally or diagonally from the cutting edge Na of the cutting blade N between the upper and lower cutting blades. When the cutting operation is performed in such a state, a vertical, horizontal, or diagonal cut is generated at the tip of the nail, and a tear is formed at the tip of the nail or meat is cut. .

この実施例の爪切り器では、このような異常を阻止するために、前記一対の支持板３の前方部分に上述の障害壁３ａを形成しており、この障害壁３ａは、図１、図２、図４に示すように切断刃板８が開き位置にあるときの刃先８ａの下端よりも上方の位置から前記爪受け台９の左右端の上面まで、或いはそれよりやや下方までに垂直に渡る壁面に形成してある。この構造では、図９のように、切断刃板８の刃先８ａと爪受け台９との間に爪Ｍを刃先８ａの切っ先８ｂ側から誤って侵入させてしまうことが障害壁３ａによって阻止され、爪先は、図７に示すように障害壁３ａに案内されて刃先８ａに正面側からしか侵入できないようになる。特に、この実施例では、障害壁３ａの前端縁を爪受け台９の少なくとも左右両端の前端縁まで延出させており、切断刃板８と爪受け台９との間の側面開口を障害壁３ａにより常時塞ぎ、爪の異常切り込防止と共に爪の飛散防止にも役立つようにしている。 In the nail clipper of this embodiment, in order to prevent such an abnormality, the above-described obstacle wall 3a is formed in the front part of the pair of support plates 3, and this obstacle wall 3a is shown in FIGS. 2. As shown in FIG. 4, vertically from the position above the lower end of the blade edge 8a when the cutting blade plate 8 is in the open position to the upper surface of the left and right ends of the claw cradle 9 or slightly below it It is formed on the crossing wall. In this structure, as shown in FIG. 9, the obstacle wall 3a prevents the claw M from intruding between the cutting edge 8a of the cutting blade plate 8 and the claw receiving base 9 from the cutting edge 8b side of the cutting edge 8a. As shown in FIG. 7, the toe is guided by the obstacle wall 3a and can only enter the cutting edge 8a from the front side. In particular, in this embodiment, the front end edge of the obstacle wall 3a is extended to at least the front end edges of the left and right ends of the claw receiving base 9, and the side opening between the cutting blade plate 8 and the claw receiving base 9 is provided as the obstacle wall. It is always closed by 3a, so that it is useful for preventing the nail from being cut and also preventing the nail from scattering.

なお、上記実施例では、切断刃板８を爪受け台９に対して開閉する機構として第１部材１と第２部材２とを軸により回動操作可能に組み合わせる構成にしているが、従来の一般的爪切り器のように二股連結弾性板を第１、第２部材とし、これを梃子レバーにより回動操作する構成を採用してもよい。 In the above-described embodiment, the first blade 1 and the second member 2 are combined so as to be pivotable by a shaft as a mechanism for opening and closing the cutting blade plate 8 with respect to the claw base 9. As in a general nail clipper, a configuration may be adopted in which the forked connection elastic plate is used as the first and second members, and this is rotated by a lever lever.
