Description

本考案は刃先を有する刃部と柄部とを金属材料又はセラミック材料で形成した刃物の柄部に設けた合成樹脂製の取手部に関するものであり、更に詳細には、取手部の両側に柄部が露出する穴又は切断部又は切欠部を形成することにより、取手部の厚さ方向の軸芯と柄部の厚さ方向の軸芯とを一致させた刃物の取手部に関するものである。   The present invention relates to a handle portion made of a synthetic resin provided on a handle portion of a blade formed of a metal material or a ceramic material with a blade portion having a cutting edge and a handle portion, and more specifically, handles on both sides of the handle portion. The present invention relates to a handle portion of a cutter in which a hole in which the portion is exposed, a cut portion, or a notch portion is formed so that an axial core in the thickness direction of the handle portion is aligned with an axial core in the thickness direction of the handle portion.

従来、刃物の柄部に取手部を形成する場合、旧来は刃物の素材に炭素鋼を用いて、柄部を短い楔状に形成して木製の取手部に焼き嵌めしたものであったが、近年では、取手部を合成樹脂製で形成したものも普及しているが、金型内に合成樹脂レジンを圧入して製作するために、刃物の柄部と取手部との夫々中心がずれるこどがあり、取手部の中心位置と柄部の中心位置とが一致しないとバランスの悪い刃物となり、特に、薄手の取手部を形成する場合に顕著と成り、歩留まりが悪くなっている実情である。   Conventionally, when forming the handle part on the handle part of the cutter, traditionally, carbon steel was used as the material of the cutter, and the handle part was formed into a short wedge shape and shrink-fitted on the wooden handle part. However, since the handle part made of synthetic resin is also popular, since the synthetic resin resin is press-fitted into the mold, the center of the handle part and the handle part of the blade will be misaligned. If the center position of the handle portion does not coincide with the center position of the handle portion, the blade becomes unbalanced. This is particularly noticeable when a thin handle portion is formed, and the yield is poor.

例えば、先に開示された、刃を形成したセラミック刃部材の後端部に金属製のあて板を合体せしめて、これら後端部及びあて板とをゴム、合成樹脂など弾性体でモールドして成るハンドル部を具備したもの（特許文献１参照）や、 中子の全体又は一部の形状が、その包丁を用いて切る食物、例えば牛や豚などの肉あるいは人参や玉ねぎなどの野菜を表示する形状に形成され、且つ中子を覆う柄は内部が透けて見える材料で形成されて中子の形状を目視することができるもの（特許文献２参照）や、棒状柄部１２の外周面に、弾性樹脂からなる二次成形体が被覆される棒状成形体の製造方法であって、前記一次成形体の棒状柄部１２の後端部に、表裏両面より凸部２２を突出させるとともに、この凸部２２を備えた一次成形体を二次成形金型４０内の所定位置に配置し、前記一次成形体の基端部１６の外周面と前記凸部の外周面とを、前記二次成形金型４０の内周面に密に圧接させ、この状態から前記二次成形体を構成する弾性樹脂を二次成形金型４０内に導入して、前記柄部の外周面を弾性樹脂で被覆するもの（特許文献３参照）が開示されている。

然し乍ら、特許文献１参照のものは合成樹脂の取手部であるが、刃部材が積層して固定しているため取手部の中心位置に刃部材があっても、あて板により中心位置が当初からづれているものであり、更に、特許文献２参照では、中子に切る食物の形状が形成され透けて見える材料で形成されているものであるが、中心位置が一致しているとは限らないものであり、更には、特許文献３参照では、棒状柄部１２の後端部に表裏両面より凸部２２を突出させているものであるが、棒状柄部１２は特性の異なる樹脂であり、金属材料又はセラミック材料で形成した刃物の柄部ではないものである。   However, although the thing of patent document 1 reference is a handle part of a synthetic resin, even if there is a blade member in the center position of a handle part because a blade member is laminated and fixed, the center position is from the beginning by a guard plate. Furthermore, according to Patent Document 2, the shape of the food to be cut into the core is formed and is made of a transparent material, but the center positions are not necessarily coincident. Furthermore, in Patent Document 3, the protrusion 22 is protruded from both the front and back surfaces at the rear end of the rod-shaped handle 12, but the rod-shaped handle 12 is a resin having different characteristics, It is not a handle portion of a blade formed of a material or a ceramic material.

A hole portion, a cut portion, or a notch portion is formed on both sides of the base end side of the handle portion in the thickness direction so as to expose a handle portion as a mold clamping portion.

本考案の刃物の取手部は、刃先を有する刃部と柄部と把持するための取手部から成り、取手部を熱可塑性樹脂の射出成形により一体に形成したもので、取手部の基端辺の両側に金型挟持部とする柄部が露出する穴部又は切断部又は切欠部を形成したことにより、金型により取手部の厚さ方向の軸心と柄部の厚さ方向の軸芯とを一致させて直接柄部を挟持するために位置決めが容易で不良品が皆無と成る極めて画期的な考案である。   The handle part of the blade of the present invention is composed of a blade part having a cutting edge and a handle part for gripping, and the handle part is integrally formed by injection molding of a thermoplastic resin, and the base end side of the handle part By forming a hole part or a cut part or a notch part in which a handle part as a mold clamping part is exposed on both sides of the mold, an axis in the thickness direction of the handle part and an axis core in the thickness direction of the handle part are formed by the mold. This is an extremely epoch-making idea that positioning is easy and there are no defective products.
