【従来の技術】[Prior Art]

従来では伸びた爪を切ったり,爪の端縁部を整形する場合には,対向して設け られた1対の刃を備え,この刃をレバー等によって駆動するせん断式の爪切り器 が一般に使用されている。この爪切り器の刃の平面への投影輪郭は,爪の端縁部 と略対応する凹円弧若しくは凹曲線に形成されているが,爪切り時においては爪 を部分的にせん断するため,せん断後の爪の端縁部は部分的に鋭利な角部が存在 する不規則な形状となるのが通常である。このため爪切り器に付属するやすり若 しくは仕上専用の研磨用やすりによって前記角部を丸めて仕上げをする必要があ り,整形に手間がかかるという問題点がある。特に利き腕側の爪切り,およびそ の後の仕上げに際しては,前記せん断および仕上,整形が極めて煩雑である。な お幼児の場合には,上記作業を本人自身が実行できる場合は極めて少なく,通常 は保護者もしくは介護者が代行するため,煩雑さは更に増加する。 Conventionally, when cutting an extended claw or shaping the edge of the claw, a shearing type nail clipper that has a pair of blades facing each other and drives the blades with a lever is generally used. It is used. The projected contour of the blade of this nail clipper on the plane is formed into a concave arc or concave curve that roughly corresponds to the edge of the nail. The edges of the posterior nail are usually irregularly shaped with some sharp corners. For this reason, it is necessary to round and finish the above corners with a rasp attached to the nail clipper or a polishing rasp exclusively for finishing, which is a problem in that shaping is time-consuming. Especially, in the nail clipper on the dominant arm side and the finishing after that, the shearing, finishing and shaping are extremely complicated. However, in the case of infants, there are very few cases where the person himself / herself can perform the above work, and the guardian or caregiver usually acts on their behalf, further increasing the complexity.

【0003】 上記問題点を解決するために,モータによって回転させられる研削部材を備え た電動式の爪研削器が種々提案されている(例えば実開昭58−143610号, 同59− 155010号, 同60−173207号公報等参照) 。In order to solve the above problems, various electric claw grinders having a grinding member rotated by a motor have been proposed (for example, Japanese Utility Model Laid-Open Nos. 58-143610 and 59-155010, (See JP 60-173207 A).

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら上記従来の電動式爪研削器においては,爪の端縁部を研削するた めの研削部材は,何れも表面が平面状若しくは凹曲面状に形成されているため, 爪の端縁部の中間を研削する場合には好都合であるが,爪の端縁部の側端を研削 することが困難であるという問題点がある。すなわち爪の端縁部の側端は,指の 腹に近接しているため,当該部分を研削部材の研削表面に充分に押圧することが できないことによる。なおこの傾向はスリット状の開口から爪を挿入する型式の ものにおいて顕著である。 However, in the above-mentioned conventional electric claw grinder, the surface of each of the grinding members for grinding the edge of the claw is formed into a flat surface or a concave curved surface. Although it is convenient to grind the middle part, there is a problem that it is difficult to grind the side edge of the edge part of the claw. In other words, the side edge of the edge of the claw is close to the ball of the finger, so that the part cannot be pressed sufficiently against the grinding surface of the grinding member. Note that this tendency is remarkable in the case where the nail is inserted through the slit-shaped opening.

【0005】 次に従来のものにおいては,爪の位置決め手段を欠如しているため,爪の研削 中における指若しくは爪の固定状態が不安定であり,研削後の仕上り形状が一定 しないのみならず,整形作業が円滑に行なわれにくいという問題点がある。特に 近年においては,単に爪の端縁部の余剰部分を除去するのみならず,美容整形上 の観点から爪の形状も美麗に,かつ個性的に整形するために上記のような電動式 爪研削器を使用する場合が増加している。また女性の場合には,爪の表面にマニ キュアを施す場合が多く,このような爪を研削する際に,爪若しくは指の位置決 めが不安定であると,マニキュア処理した爪の表面を損傷することともなり,研 削後の美感を著しく損なうという問題点がある。Next, in the conventional device, because the nail positioning means is lacking, the fixed state of the finger or the nail during grinding of the nail is unstable, and the finished shape after grinding is not constant. However, there is a problem that it is difficult to perform the shaping operation smoothly. In particular, in recent years, in order to not only simply remove the surplus portion of the edge of the nail but also to shape the nail beautifully and individually from the viewpoint of cosmetic surgery, the electric nail grinding as described above is performed. The number of cases where the vessel is used is increasing. In addition, women often apply nail polish to the nail surface, and when grinding such nails, the position of the nail or finger is unstable. There is also a problem that it may be damaged, and the aesthetics after polishing are significantly impaired.

【0006】 本考案は,上記従来技術に存在する問題点を解決し,爪の位置決めが正確に行 なえると共に,研削後の爪の仕上りが美麗になるように改良した電動式爪研削器 を提供することを目的とする。The present invention solves the above-mentioned problems existing in the prior art, and provides an electric claw grinder improved so that claw positioning can be performed accurately and the finish of claws after grinding is beautiful. The purpose is to do.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するために,本考案においては,電池およびモータを収容して なる中空筒状のケースの上端にモータの出力軸を突出させ,研削表面を凸曲面に 形成すると共に嵌合軸を設けてなる研削部材を前記出力軸と着脱可能に接続し, 前記ケースの上端部に研削部材の表面を被覆するようにカバーを着脱可能に設け ,このカバーにスリット状の爪挿入孔を開口すると共に,この爪挿入孔の長手方 向に沿って爪の表面と摺接する突当部を突設する,という技術的手段を採用した 。 In order to achieve the above object, in the present invention, the output shaft of the motor is projected at the upper end of the hollow cylindrical case accommodating the battery and the motor, the grinding surface is formed into a convex curved surface, and the fitting shaft is provided. The provided grinding member is detachably connected to the output shaft, and a cover is detachably provided on the upper end of the case so as to cover the surface of the grinding member, and a slit-like claw insertion hole is opened in this cover. At the same time, we have adopted the technical means of projecting an abutting part that makes sliding contact with the surface of the claw along the longitudinal direction of the claw insertion hole.

【0008】 本考案において研削部材の凸曲面は,例えば円錐面,球面のみならず,縦断面 輪郭が曲線を形成する曲面とすることができると共に,上記の曲面を複数個組み 合せた凸曲面とすることができる。In the present invention, the convex curved surface of the grinding member can be, for example, not only a conical surface or a spherical surface, but also a curved surface whose vertical cross-section contour forms a curve, and a convex curved surface formed by combining a plurality of the above curved surfaces. can do.

【0009】 また研削部材を構成する材料としては,ダイヤモンド粒子若しくはセラミック 粒子のような硬質微粒子を結合材料によって結合した砥石であってもよく,また 鋼のような硬質金属材料によって形成し,研削表面に複数個の細かい刃を設けた 研削具としてもよい。Further, the material constituting the grinding member may be a grindstone in which hard particles such as diamond particles or ceramic particles are bonded by a bonding material, or may be formed by a hard metal material such as steel and used as a grinding surface. It may be a grinding tool in which a plurality of fine blades are provided.

【0010】 更にカバーに設けるスリット状の爪挿入孔は,平面に対する投影形状において 直線状とするのみならず,曲線状とすることもでき,またスリットの幅寸法を特 に側端部において中間部のそれより大に形成してもよい。Further, the slit-like claw insertion hole provided in the cover can be not only linear in the projected shape on the plane but also curved, and the width dimension of the slit is especially the middle portion at the side end. It may be formed larger than that.

【作用】[Action]

上記の構成により,爪の端縁部の研削に際しては,爪の表面を突当部に当接さ せた状態で爪の端縁部を爪挿入口に挿入し,指を突当部に沿って移動若しくは回 動させれば,容易かつ均一に爪の端縁部を研削することができる。 With the above configuration, when grinding the edge of the nail, insert the edge of the nail into the nail insertion hole with the surface of the nail in contact with the abutting part, and place the finger along the abutting part. If it is moved or rotated in this way, the edge of the claw can be ground easily and uniformly.

Reference numeral 5 denotes a bottom lid, which is detachably attached to the bottom portion (left end in FIG. 1) of the case 1 and is formed so as to press and fix the battery 2 via a coil spring 6.

【0013】 7は研削部材であり,例えばプラスチック材料によって円板状の基板8と嵌合 軸9とを一体に形成すると共に,砥石10を基板8の表面に一体に固着して構成 する。なお砥石10は,例えばダイヤモンド粒のような硬質微粒子を結合材料に よって結合し,円板状にかつ表面を例えば球面状に形成する。嵌合軸9は前記モ ータ3の出力軸4と着脱可能,かつ出力軸4と一体回転可能としてある。11は コイルばねであり,出力軸4に固着したカラー12と基板8との間に介装する。Reference numeral 7 denotes a grinding member, which is formed by integrally forming a disk-shaped substrate 8 and a fitting shaft 9 of a plastic material, for example, and fixing a grindstone 10 to the surface of the substrate 8 integrally. The grindstone 10 is formed by combining hard particles such as diamond particles with a bonding material to form a disk shape and a spherical surface. The fitting shaft 9 is attachable to and detachable from the output shaft 4 of the motor 3 and rotatable integrally with the output shaft 4. Reference numeral 11 is a coil spring, which is interposed between the collar 12 fixed to the output shaft 4 and the substrate 8.

【0014】 次に13はカバーであり,前記ケース1の上端部に,研削部材7の砥石10の 表面を被覆するように着脱可能に設ける。カバー13にはスリット状の爪挿入孔 14を開口すると共に,この爪挿入孔14の長手方向に沿って突当部15をカバ ー13と一体に設ける。なおカバー13の内周面は,前記砥石10の表面と対応 する凹球面に形成し,砥石10の表面と僅かに摺接するか,微小間隙を介して対 向するように設ける。また爪挿入孔14およびこの爪挿入孔14に沿う突当部1 5の表面は,図2(a)に示すように直線状に形成してもよく,一方図2(b) に示すように曲線状に形成してもよい。更に爪挿入孔14の開口位置は,砥石1 0の回転中心から若干距離を離して設けることが好ましい。Next, 13 is a cover, which is detachably provided on the upper end of the case 1 so as to cover the surface of the grindstone 10 of the grinding member 7. A slit-shaped pawl insertion hole 14 is opened in the cover 13, and an abutting portion 15 is provided integrally with the cover 13 along the longitudinal direction of the pawl insertion hole 14. The inner peripheral surface of the cover 13 is formed as a concave spherical surface corresponding to the surface of the grindstone 10 and is provided so as to make a slight sliding contact with the surface of the grindstone 10 or to face through a minute gap. Further, the surface of the claw insertion hole 14 and the abutting portion 15 along the claw insertion hole 14 may be formed in a linear shape as shown in FIG. 2 (a), while on the other hand, as shown in FIG. 2 (b). It may be formed in a curved shape. Further, the opening position of the claw insertion hole 14 is preferably provided at a distance from the center of rotation of the grindstone 10.

【0015】 上記の構成により,ケース1に設けられたスイッチ(図示せず)をON状態に すると,モータ3の出力軸4を介して研削部材7が回転するから,鎖線にて示す ように爪を爪挿入孔14に挿入して砥石10の表面に押圧すれば,爪の端縁部を 研削することができる。この場合,爪の表面を突当部15に当接させた状態で, 突当部15に沿って指を移動若しくは回動させることにより,爪の端縁部を容易 かつ均一に研削することができる。この場合爪の位置は突当部15によって正確 に位置決めされ,前後に倒れることがないため,爪の端縁部以外の部位が非所望 に研削されることがない。従って爪の表面にマニキュア処理してある場合におい ても,その表面が損傷されることなく,研削後も美感を保持できるのである。With the above configuration, when the switch (not shown) provided on the case 1 is turned on, the grinding member 7 rotates via the output shaft 4 of the motor 3, so that the claws shown by the broken line By inserting the tool into the claw insertion hole 14 and pressing it against the surface of the grindstone 10, the edge of the claw can be ground. In this case, the edge of the nail can be easily and uniformly ground by moving or rotating the finger along the abutting portion 15 with the surface of the nail abutting against the abutting portion 15. it can. In this case, the position of the claw is accurately positioned by the abutting portion 15 and does not fall back and forth, so that the parts other than the edge part of the claw are not undesirably ground. Therefore, even if the surface of the nail is treated with nail polish, the surface is not damaged and the aesthetics can be maintained even after grinding.

【0016】 次に爪の端縁部の側端を研削する場合には,例えば図2(a)に示すように指 を若干傾けることにより,容易に研削を行なうことができる。この場合,爪挿入 孔14の幅寸法を,側端部において中間部のそれより大に形成し,例えば鼓状に しておくと,上記爪の端縁部の側端の研削が更に容易となる。上記爪挿入孔14 の形成例は,図2(a)のみでなく,図2(b)についても同様である。Next, when the side edge of the edge of the claw is ground, the grinding can be easily performed by slightly tilting the finger as shown in FIG. 2A, for example. In this case, if the width dimension of the claw insertion hole 14 is formed to be larger than that of the intermediate portion at the side end portion and is, for example, drum-shaped, the side edge of the edge portion of the above-mentioned nail can be ground more easily. Become. The example of forming the claw insertion hole 14 is the same not only in FIG. 2 (a) but also in FIG. 2 (b).
