Description

【０００１】
【発明の属する技術分野】
本発明は、衝撃力を利用した包丁、ナイフ、又は、毛切りや糸切りのような切断器具に関するものである。
【０００２】
【従来の技術】
従来、糸や毛糸、皮ひも、線材等を切るにはハサミやニッパが使われている。また、骨付き肉や小魚を刻むときは、包丁でなくハサミを使うことが多い。ハサミは先が尖っていることが多く危険であると同時に、切れずに刃が開き、刃の間に挟まることもある。また、強い力が必要である。漬物等をまな板で切るときに最後の一皮が残るときがある。毛を刈るものにバリカン式のものがあり、毛を抜くものに毛抜きがある。バリカン式は、微細部に向かない。毛抜きは毛を抜くため痛い。また、毛根を痛めたりする。鼻毛等の微細部の毛を切るときにはハサミを使う。ハサミは微細部の毛を切るときに危なく、皮膚を痛めることがある。一般に包丁、ハサミ、バリカン、毛抜きは、ステンレス、鉄等の材料で形成され、ステンレス材以外では表面にニッケル、クロム等のメッキで仕上げられたものが多い。これらは肌アレルギーを起こすことがある。
【０００３】

[Prior art]
Conventionally, scissors and nippers are used to cut yarn, wool, leather, wire, and the like. Also, when cutting boned meat and small fish, scissors are often used instead of knives. Scissors are often pointed and dangerous, and at the same time, the blades open without being cut and can be pinched between the blades. Also, a strong force is necessary. There are times when the last skin remains when cutting pickles etc. with a cutting board. Hair clippers are used to cut hair, and hair removal is used to remove hair. The clipper type is not suitable for fine parts. Tweezers hurt because they pull hair. It also hurts the hair roots. Use scissors when cutting fine hair such as nose hair. Scissors are dangerous when cutting fine hair and can hurt the skin. In general, kitchen knives, scissors, clippers and tweezers are made of materials such as stainless steel and iron, and the surfaces other than stainless steel are often finished by plating with nickel, chromium or the like. These can cause skin allergies.

Claims

A cutting tool having a thin plate-like base portion provided with a blade portion along the longitudinal direction and extending toward the base end side, connected to the handle, extending from the handle along the base portion, and continuously elastic to the cutting device side. An impact generating ridge formed of an applied elastic member, an impact generating convex portion or an impact generating concave portion formed on the cutting instrument side of the tip of the impact generating ridge, and the impact generating convex portion or the impact generating concave portion; The cutting tool includes an impact generating portion including two or more substantially hemispherical impact generating concave portions or impact generating convex portions that are cut and arranged in a direction orthogonal to the blade portion on the cutting tool to be fitted, and the blade portion of the cutting instrument When a load for cutting is applied, the impact generating convex portion or the impact generating concave portion of the impact generating portion moves and fits the two or more impact generating concave portions or the impact generating convex portions in the load direction. Cutting using impact characterized by occurrence of impact Ingredients.

A cutting instrument that provides elasticity so that the distal ends of a pair of gripping rods opposed to each other are constantly separated to connect the proximal end side and has a blade portion on at least one holding piece along the distal end side, Each of the plate-like impact generating portions projecting so as to come into contact with each other from a pair of gripping rods, and an impact generating convex portion projecting at a position shifted from each of the impact generating portions, A cutting device using an impact, wherein when a load for cutting is applied to the blade portion of the cutting device, an impact is generated by the impact generating convex portions of the impact generating portion getting over each other.

A cutting instrument that provides elasticity so that the distal ends of a pair of gripping rods opposed to each other are constantly separated to connect the proximal end side and has a blade portion on at least one holding piece along the distal end side, Each of the plate-like impact generating portions projecting so as to come into contact with each other from a pair of gripping rods, an impact generating convex portion projecting on the one impact generating portion, and the impact generating convex portion, An impact generating recess recessed in the other impact generating portion at a shifted position, and the impact generating convex portion of the impact generating portion generates an impact when a cutting load is applied to the blade portion of the cutting instrument. A cutting instrument using an impact, wherein an impact is generated by falling into the concave portion for use.

A cutting instrument that provides elasticity so that the distal ends of a pair of gripping rods opposed to each other are constantly separated to connect the proximal end side and has a blade portion on at least one holding piece along the distal end side, Each of the impact generating parts having curved surfaces protruding so as to come into contact with each other from a pair of gripping rods, and an impact generating roller or an impact generating supported by a spring sandwiched between the curved surfaces of the respective impact generating parts and a use sphere, away from the impact generating unit each curved impact-generating roller or impact generating sphere projecting portion is sandwiched in between burdening for blade portion for cutting said cutting instrument cutting instrument impact using an impact, characterized in that generated by playing to.

The blade part or the blade receiving part for cutting | disconnection was formed in the clamping part of the other side which opposes the blade part with which the one side of the said pair of holding rods was provided, The one of Claims 2-4 characterized by the above-mentioned. Cutting device using impact.

6. The method according to claim 2, wherein a distance between the facing surfaces of the gripping rods in a state where the tips of the pair of gripping rods are closed is within twice as long as a distance between the blade portion and the outer peripheral end of the tip. A cutting instrument using the impact according to one item.

The cutting device using an impact according to any one of claims 2 to 6, wherein at least a portion of the cutting device that touches human skin is formed or coated with titanium, silver, or ceramic.
