Description

本発明は、深爪することなく、爪を指先より内方の爪床先端近傍まで深く切ることができる爪切り具に関するものである。 The present invention relates to a nail clipper capable of cutting a nail deeply to the vicinity of the tip of a nail bed inward of a fingertip without deep nailing.

従来、深爪するとデリケートな爪床が露出してしまい、この爪床が露出することで様々な不具合（例えば、爪床に触れるだけで痛みが生ずる、細菌の浸入により感染症を発症する、巻爪の原因となる等）が生ずるおそれがあることから、従来の爪切り具の殆どは、深爪防止策として、下側爪切部の爪切刃の下方に指先が当接する指先当接板部（爪切刃の下端から垂直状態若しくは内側に向かって傾斜状態に設けた板部）を設け、指先がこの指先当接板部に当たることで爪切刃が奥に入り込むことを阻止する構成となっている。 Conventionally, when deep nailing, a delicate nail bed is exposed, and exposure of the nail bed causes various problems (for example, pain is caused by only touching the nail bed, which causes an infection due to bacterial infiltration, toenails) In most of the conventional nail clippers, as a measure to prevent A plate provided vertically or inward from the lower end of the claw cutting edge) is provided, and a finger tip abuts against the fingertip contact plate to prevent the claw cutting edge from entering the back. There is.

即ち、従来の爪切り具は、指先から突出した爪を切り、爪の長さを指先とそろえる程度の深さ（長さ）に切るのに適した構造となっていて、深めに爪を切ることには適していないものとなっている。 That is, the conventional nail clipper has a structure suitable for cutting the nail projecting from the fingertip and cutting the length of the nail to a depth (length) that aligns the length with the fingertip, and cuts the nail deeply It is not suitable for anything.

しかしながら、例えば弦楽器奏者やロッククライマー、マッサージ師、美容師などは、職業柄、爪が伸びていることで様々な不具合が生じることから、常に爪をできるだけ短い状態（深爪に近い状態）にしており、このような人たちにとっては、従来の深爪防止策が施された爪切り具は非常に使いにくいものであった。 However, for example, string players, rock climbers, masseurs, cosmetologists, etc. always keep their nails as short as possible (close to deep nails) because various problems are caused by the extension of the occupation pattern and the nails. However, for such people, the nail clipper with the conventional deep nail prevention measures was very difficult to use.

即ち、従来の深爪用爪切り具で、爪をできるだけ深い位置まで切るには、例えば、爪切刃を寝かせた状態（水平に近い状態）にして無理に爪の隙間に爪切刃を入れ込んだり、下側爪切部の外面を指先に強く押し付けて無理やり爪切刃を奥側に入れ込んだりしなければならず、このような方法で無理に爪を深めに切ることで、爪をきれいに切ることができず、また、無理な押し付けで痛みが生じたり、誤って指を切ってしまうことがあった。 That is, in order to cut the nail as deep as possible with a conventional deep nail clipper, for example, with the nail cutting edge laid down (nearly horizontal), the nail cutting blade is forcibly inserted into the gap of the nail You have to push the outer surface of the lower nail cut part strongly against the finger and force the nail cutting blade into the back side by force, and you can clean the nail by cutting the nail by force in this way. I could not cut it, and I was forced to push it, causing pain or accidentally cutting my finger.

本発明は、上述のような現状の問題に鑑みなされたものであり、容易に且つ安全に爪を深めに切ることができる実用性に優れた画期的な爪切り具を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems of the present invention, and it is an object of the present invention to provide a highly practical and innovative nail clipper which can cut a nail easily and safely. I assume.
