この発明は、 鋏の軽量化と模様化の改良に関する。 背景技術  The present invention relates to weight reduction and improvement of patterning of scissors. Background art
理美容に用いられる鉄は、 6インチのもので約 6 0 gの重量であり、 8ィ ンチのもので約 8 0 gの重量である。 この重量自体、 鋏を手にした場合にはそ れほど重く感ずるものではないが、 理容師 ·美容師の様にほぼ 1日中鋏を手に している場合には、 上記重量でも重く、 軽量化が望まれている。 軽量化の一例として、 鋏材料にチタン合金を用いたものがあり、 チタン合金 で形成した刃体に、 ステンレス材料で形成した板状の刃を刃先部分に貼り付け たものがある。  Iron used for hairdressing is 6 inches and weighs about 60 g, and 8 inches is about 80 g. This weight itself does not feel so heavy when you hold the scissors in your hand, but if you hold the scissors almost all day like a barber or hairdresser, the weight is heavy, Lightening is desired. As an example of weight reduction, there is a scissor material using a titanium alloy, and a blade body made of a titanium alloy and a plate-shaped blade made of a stainless material adhered to a cutting edge portion.
或いはチタン合金自体を焼き入れしてこれを研磨して刃にしたものもある。 また一般に理美容の技術者は力ット鋏ゃ梳鋏を多数使い分けて作業を進める が、 持ち替える都度に重さが大きく異なると、 手や指の感覚が狂い、 微妙な力 ット作業に好ましくない。 その為、 梳鋏のように櫛刃の削り出し加工により削 つた分だけ重量の軽くなるものは、 わざわざ重くしてカツト鋏に近い重量にし、 鋏の持ち替えによっても技術者の感覚に狂いの生じないような配慮が成されて いる。 しかし軽量なチタン合金を鋏材料にすると鋏全体の軽量化が実現するものの 軽量化が顕著すぎる嫌いがある。 現在主流となっているステンレス材料の鋏と この様な軽量著しい鉄を混在して使用すると、 持ち替えの都度に生ずる重量差 が大き過ぎ、 技術者の指先の感覚を狂わせるので敬遠されている。 この点、 手持ちの多数の鉄の全てを一度に軽量化された鉄に替えることによ り、 上述した重量差による問題は無くなるが、 一度に全てを替えることは経済 時に負担である。 また理美容には様々な種類の鋏が用いられており、 理美容の 技術者はこれらの多数を揃え、 この多数の鋏を色々に使い分けて作業をしてい るのである。 しかし現在、 チタン合金製の鋏はその中の一部の種類の鋏しか提 供されておらず、 従って理美容業者が揃えている鋏を全てチタン合金製に替え ようとしても揃えることはできない。 Alternatively, a titanium alloy itself is quenched and polished to form a blade. In general, barber and beauty technicians use a large number of power scissors and comb scissors to carry out the work. Absent. Therefore, if the weight of the comb blade is reduced by the shaving process of the comb blade, such as comb scissors, the weight of the comb scissors is reduced to a weight close to that of the cut scissors. There are no considerations. However, when a lightweight titanium alloy is used as a scissor material, the weight of the entire scissors can be reduced, but the weight reduction is remarkably disliked. The use of a mixture of stainless steel scissors, which is currently the mainstream, and such lightweight and remarkable iron, is avoided because the weight difference that occurs each time it is changed is too large, and it disturbs the technician's fingertips. In this regard, by replacing all of the many irons on hand with lighter iron at once, the above-mentioned problem due to the weight difference is eliminated, but replacing all at once is a burden on the economy. In addition, various types of scissors are used in hairdressing and beauty, and hairdressing technicians prepare many of these and use these many scissors in various ways. However, at present, only some types of scissors made of titanium alloy are provided, so it is not possible to replace all scissors provided by hairdressers with titanium alloy.
また、 チタン合金は加工の自由度が低いためこれが製造上の負担となってい る。 また更に、 チタン合金による鋏は研磨するとチタン合金の粉末が出るが、 チタンの発火点が低いためチタン粉末から出火する事故例が報告されており、 好ましくない。 また理美容の鋏の他に、 ペット用の鋏も提供されている。 しかしその数や種 類が少ないため、 理美容の鋏の中の比較的大きなものがぺッ卜用に転用されて 用いられる傾向にある。 理美容の鋏で比較的大きなものには 1 0インチ程度の ものがあるが、 その分重量もあり、 この様な重量の有る鋏は一層の軽量化が望 まれている。 なお鋏は一般に、 特定の単一金属材料、 例えばステンレスを主材料とし、 こ れを所望の形状に加工した後、 焼き入れなどの熱処理により刃先部分を硬化さ せてある。 ただ単一金属材料によるため、 鋏の色彩はその主材料の金属色のも のが大半であり色調が単調である。 ごく一部にはメツキその他で青色、 金色な どに表面着色したものがある。 しかし鈇は使用期間中に度々研磨して切れ味を 保持しなければならず、 よってこの研磨によつて着色が剥がれる問題がある。 また、 鉄はデザイン性を高めるために、 刃表や柄などに意匠的な施しがされ る場合がある。 例えば、 刃表にメーカー名、 マークほかデザイン的な刻印模様 を凹設し、 ここに塗料を塗布したものがある。 ただ、 刻印は塗料を刃表に固着 させることを目的とするため、 塗布した塗料で埋まる程度の浅い凹設になって いる。 しかも、 鋏は、 切れ味回復のため定期的に研磨をしなければならず、 こ の研磨によって前述した模様が消えてしまう。 Titanium alloys have a low degree of freedom in processing, which is a burden on manufacturing. Furthermore, scissors made of titanium alloy give powder of titanium alloy when they are polished, but since the ignition point of titanium is low, there have been reports of accidents involving fire from titanium powder. In addition to hairdressing scissors, pet scissors are also available. However, because of the small number and variety, relatively large scissors for hairdressing and beauty scissors tend to be diverted and used for kitting. Some relatively large hairdressing scissors have a size of about 10 inches, but the weight is correspondingly large, and it is hoped that the scissors with such weight will be even lighter. Generally, scissors are made of a specific single metal material, for example, stainless steel as a main material, processed into a desired shape, and then hardened at a blade edge portion by heat treatment such as quenching. However, since they are made of a single metal material, the color of the scissors is mostly the metal color of the main material, and the color tone is monotonous. A very small part of the surface is colored, such as blue or gold. However, 鈇 has to be polished frequently during use to maintain its sharpness, and thus there is a problem that the coloring is removed by this polishing. In addition, iron is sometimes given a decorative design on the blade surface or handle to enhance the design. For example, there is a design in which a manufacturer's name, a mark, and a design-like engraving pattern are recessed on the blade surface, and paint is applied here. However, since the stamp is intended to fix the paint on the blade surface, it must be a shallow recess that can be filled with the applied paint. I have. Moreover, the scissors must be periodically polished to restore sharpness, and this polishing will erase the above-mentioned pattern.
この様な研磨は、 研磨布を張った円盤で研磨するのが一般的であり、 新品の 鋏は初回の研磨で塗料が消えてしまっている。 また色が消えても凹設された文 字など模様は残っているが、 これも研磨を繰り返すことによって、 次第に削れ て消えてゆく。 1日中同じ鋏を使うのであれば、 当所、 連続線であった刃先線 と刃マチ線とが、 1年程度の使用で段差ができる程度に削られる。 以上の問題を鑑み、 本願発明の目的とするところは、 軽量化が可能であると 共に、 その軽量化の際にはどの程度の軽量にするかといつた程度調整が可能で あり、 また軽量化することがそのまま模様の施しとなり、 或いは、 鋏のカラー 化が可能であり、 また研磨によっても前述の模様や着色を失わない鋏を提供す ることにある。 発明の開示  Generally, such polishing is performed using a disk covered with a polishing cloth, and new scissors lose their paint after the first polishing. Despite the disappearance of the color, there are still patterns such as recessed characters, but these are also gradually scraped off by repeated polishing. If the same scissors are used throughout the day, the continuous cutting edge and gusset line will be sharpened to a level difference after about one year of use. In view of the above problems, it is an object of the invention of the present application to be able to reduce the weight and to adjust how much the weight is reduced when the weight is reduced. The purpose is to provide a scissor that can be provided with a pattern as it is, or the scissors can be colored, and scissors that do not lose the above-described pattern and coloring even by polishing. Disclosure of the invention
以上の課題を解決するため、 本願請求項 1記載の発明は、 鋏の刃表に実質的 な凹部を設けたことを特徴とした。  In order to solve the above problems, the invention described in claim 1 of the present application is characterized in that a substantial concave portion is provided on the blade surface of the scissors.
実質的な凹部とは、 鋏の研磨によっても、 その凹部が削れて消滅することの ない深さである。 凹部の形状、 大きさ、 配置は刃体強度に影響の少ないのが好 ましい。 主材料とは、 上記従来技術の欄で述べた、 ステンレスなど特定の単一 金属材料である。 この様にして、 鋏は、 その刃体に設けた凹部により肉が落とされた状態とな るため、 その分、 軽量化が成され、 これを手にして 1日中使用していても、 負 担感が無い。 また凹部の形状 ·配置を工夫して凹部内の総容量を調整すること により軽量化する重量の調整が自由に行うことができる。  A substantial concave portion is a depth that the concave portion does not disappear by being polished by scissors. It is preferable that the shape, size, and arrangement of the recess have little effect on the blade strength. The main material is a specific single metal material such as stainless steel described in the section of the prior art. In this way, the scissors are in a state where the meat is cut off by the concave portion provided in the blade body, so that the weight is reduced by that much, even if you use it all day long, There is no burden. Further, by adjusting the shape and arrangement of the concave portion and adjusting the total capacity in the concave portion, the weight can be freely adjusted to reduce the weight.
従って、 理美容の技術者は、 各自が現在保有している鋏と比較して、 軽すぎ ない程度の軽量化のなされた鋏を選ぶことが可能になる。 例えば、 技術者は手 持ちの多数の鋏の平均的重量を基準にして、 手にしても感覚が狂わない程度に 軽量化された鋏 (例えば重量が 5 %〜 1 0 %軽量化された鋏) を手持ちの鋏に 加えることができ、 多数保有している鋏の中から少しずつ軽量化された鋏に交 換してゆくことができる。 Therefore, hairdressing technicians will be able to select scissors that are not too light in weight compared to their current scissors. For example, a technician would use the average weight of a large number of Weight-reduced scissors (eg, 5% to 10% lighter) can be added to hand-held scissors, and a large number of scissors can be replaced with lighter weight scissors. I can do it.
凹部の外観形状は自在に設けてよく、 例えば幾何学模様、 文字、 マーク、 な んらかの絵などの形状に形成してもよく、 デザイン的に優れたものとなる。 ま た模様などに形成された凹部は、 刃表が研磨され凹部が削られても、 実質的に 凹部として或る程度の深さになつているので消滅しないのである (なお刃先間 際の凹部は例外として、 研磨される刃先と共に消滅するが本発明の優れた効果 には支障がない)。 請求項 2記載の発明では、 所定の金属材料を主材料とした請求項 1記載の鋏 において、 凹部に前記主材料と異なる材料を充填して成る充填部を設けた。 これにより鋏の色彩が (主材料と充填部の) 2色或いはそれ以上となり、 従 来、 鋏は金属色が中心であったものに色彩をもたらすことができる。 また従来 でも柄や握りの部分にカラープラスなどを用いたカラフルなものもあったが、 刃表に色彩を施すものはなく、 本発明によりこれが可能になった。 また更に、 凹部を細かく或いは小さく多数配置すれば、 ここに設けられた充填部の色彩に より遠目に見た場合には刃体への着色効果が得られる。 凹部を文字、 模様など の形状に形成するのであれば、 例えば金属色の刃体にこれと色彩の異なる充填 部で文字、 模様などを形成することができる。 しかも凹部が削れて消滅するこ とのない深さであり、 従って先に請求項 1で述べた 「実質的な凹部」 には、 少 なくとも背景技術として述べた 「塗布した塗料で埋まる程度の浅い凹設」 にな つているものは含まない。 この様な凹部に充填部を設けるので、 刃表が研磨さ れ充填部が削られてもその下から新たな充填部が途切れることなく現れ、 充填 部で描いた文字や模様の消えることはない。  The external shape of the recess may be freely provided, for example, it may be formed into a shape such as a geometric pattern, a character, a mark, or some kind of picture, so that the design is excellent. In addition, even if the concave portion formed in the pattern or the like is polished and the concave portion is shaved, the concave portion is practically formed as a concave portion to a certain depth and thus does not disappear. Extinguishes with the edge being polished, but does not interfere with the excellent effect of the present invention). In the invention according to claim 2, in the scissors according to claim 1, wherein a predetermined metal material is used as a main material, a filling portion formed by filling a concave portion with a material different from the main material is provided. This allows the scissors to have two or more colors (of the main material and the filling part), and in the past, scissors can give colors to those that were mainly metallic. In the past, there was also a colorful one using a color plus or the like for the handle or grip portion, but there was no one that applies color to the blade surface, and this is made possible by the present invention. Furthermore, if a large number of concave portions are arranged finely or smallly, a coloring effect on the blade body can be obtained when viewed from a long distance by the color of the filling portion provided here. If the concave portion is formed in the shape of a character, a pattern, or the like, a character, a pattern, or the like can be formed, for example, on a metal-colored blade with a filling portion having a different color from the metal blade. Moreover, the depth is such that the concave portion is not scraped off and disappears. Therefore, the “substantial concave portion” described in claim 1 has at least the “submerged portion filled with the applied paint” described as the background art. Excludes those with “shallow recess”. Since the filling part is provided in such a concave part, even if the blade surface is polished and the filling part is shaved, a new filling part will appear without interruption from below, and the characters and patterns drawn in the filling part will not disappear. .
主材料と異なる材料は 1種類でも多種類でもよい。 また請求項の 「充填して」 との記載は製造方法を記載したものではなく、 できあがった状態を表現したも のである。 よって、 充填部の形成はどのような方法であってもよい。 請求項 3記載の発明では、 主材料と異なる材料を前記主材料より軽量な材料 としたので、 鋏が軽量化できる。 主材料がステンレスであるなら、 軽量な材料 として、 プラスチック、 グラスファイバー、 アルミニューム、 力一ボン、 フエ ルト、 ベークライ卜が例示できるが、 これに限らない。 請求項 4記載の発明では、 鋏の刃体の刃表から刃裏に貫通する穴部を透設し た。 穴部は刃体幅の中央位置が刃体強度の均一化の面で好適であり、 この様な 中央位置に刃体の基端から先端にかけて穴部を設けることができるがこれに限 らない。 穴部は小さなものを基端から先端にかけて多数配設するものでもよく、 一つの穴部を基端から先端にかけ溝のように長く形成してもよく、 穴部の総容 量に対応した材料分だけ重量の軽量化が図れる。 また請求項 1の場合と同様に 穴部の形状 ·配列を工夫して穴部総容量を調整することにより軽量化する重量 の調整が自由に行うことができる。 更に穴部の周縁形状を各種の模様形状に形 成することにより鋏のデザィン性を高めることができ、 特に穴が透けて向こう が見えるので穴部の模様形状や穴部の存在自身が見てよく分かり、 この様な穴 部にデザインを施すとそのデザイン効果が引き立つ。 或いは、 穴部を多数設け、 その際の穴部のを模様状に配置することによつてもデザィン性を高めることが できる。 或いは、 個々の穴部を模様形状に形成し、 更にこれら複数の穴部を模 様状に配置すれば、 よりデザイン性が高まる。 また請求項 5記載の鉄では、 所定の金属材料を主材料とした請求項 5記載の 鋏において、 穴部に前記主材料と異なる色彩の材料を充填して成る充填部を設 けた。 請求項 2同様に鋏のデザイン性が広がり、 配置が着色されたように見せ ることができる。 請求項 6記載の発明では、 前記主材料より軽量な材料を穴部に充填した。 こ れは穴部の大きさ ·形状によっては穴部に髪が引つかかったり詰まったりする 場合には、 これらを防ぐことができる効果がある。 また鋏の軽量化にも寄与す る。 更に透設する穴部の大きさや ·形状や穴部の配置数によっては、 鋏の曲げや 捻りに対する機械強度を低下させる場合もあるが、 充填材料の充填によって機 械強度を補強する効果が得られる。 その際、 請求項 7記載の発明で充填部に埋め込み状態となるリブ部を穴部に 架け渡し状態で有するようにしたので、 充填部の穴部からの脱離を防ぐ効果が 得られると共に、 コンクリートに埋設させる鉄筋の様に、 充填部の強度を補強 する効果が得られ、 最終的には、 刃体強度の補強となる効果が得られる。 図面の簡単な説明 The material different from the main material may be one kind or many kinds. In addition, the description “filled” in the claims does not describe a manufacturing method but expresses a completed state. Therefore, the filling portion may be formed by any method. According to the third aspect of the present invention, since the material different from the main material is made lighter than the main material, the weight of the scissors can be reduced. If the main material is stainless steel, examples of lightweight materials include plastic, glass fiber, aluminum, bonbon, felt, and bakelite, but are not limited thereto. In the invention according to claim 4, a hole penetrating from the blade surface of the blade body of the scissors to the back of the blade is provided. The hole is preferably located at the center of the blade width in terms of uniform blade strength, and a hole can be provided at such a center from the base end to the tip of the blade, but is not limited to this. . A number of small holes may be provided from the base end to the tip, and a single hole may be formed as long as a groove from the base to the tip, and a material corresponding to the total capacity of the hole The weight can be reduced accordingly. As in the case of the first aspect, by adjusting the shape and arrangement of the holes and adjusting the total capacity of the holes, the weight to be reduced can be freely adjusted. Furthermore, by designing the peripheral shape of the hole into various patterns, the design of the scissors can be enhanced.In particular, since the hole can be seen through the hole, the pattern shape of the hole and the existence of the hole itself can be seen. It is easy to understand, and if you design a hole like this, the design effect will be more pronounced. Alternatively, the design can be improved by providing a large number of holes and arranging the holes in a pattern at that time. Alternatively, if the individual holes are formed in a pattern shape and these holes are arranged in a pattern, the design is further enhanced. In the iron according to the fifth aspect, in the scissors according to the fifth aspect, wherein a predetermined metal material is used as a main material, a filling portion formed by filling a material having a different color from the main material is provided in the hole. As in the case of claim 2, the design of the scissors is expanded, and the arrangement can be made to look colored. In the invention according to claim 6, the hole is filled with a material lighter than the main material. This is effective in preventing hair from being caught or clogged in the hole depending on the size and shape of the hole. It also contributes to weight reduction of the scissors. Furthermore, depending on the size, shape, and number of holes to be provided, the mechanical strength against bending and twisting of the scissors may be reduced, but the effect of reinforcing the mechanical strength by filling the filler material is obtained. Can be At this time, the invention according to claim 7 has a rib portion embedded in the filling portion in a state of being bridged over the hole portion, so that the effect of preventing the filling portion from detaching from the hole portion is obtained, Like reinforcing steel buried in concrete, it has the effect of reinforcing the strength of the filling part, and ultimately the effect of reinforcing the blade strength.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below.
(実施例 1 );図 1に示す鋏 1はカツ卜鉄であり、 ステンレスの刃体 2の 2本が 枢着されたものである。 鋏はこれを握る技術者の手前側刃体が静刃 3となり、 理髪される人の頭側となる刃体が動刃 6となる。 従って静刃 3が人目に触れや すい位置となるが、 この静刃 3となる刃体 2には、 図 2〜図 3に示すようにそ の刃表 Aに菱形の格子の溝状に凹部 4が設けられている。 凹部 4は幅が 1ミリ で 3ミリ間隔に均等間隔に配置されたものである。 また、 何れの凹部 4も、 図 4〜図 5に示すよう刃裏 Bから 0 . 8ミリのところまでの深さに設けられてい る。 つまり凹部が、 この凹部 4の底部と刃裏 Bとの間の厚みが略一定になる様 な深さの凹部に形成されているのである。 なお厚さが 0 . 8ミリ以下となる刃 先部分は、 この凹部がない状態 (図 1、 図 4の X) となる。 この鋏の製造は以下の方法による。  (Example 1); Scissors 1 shown in FIG. 1 are cut iron, and two stainless steel blades 2 are pivotally mounted. As for the scissors, the blade on the front side of the technician holding the scissors is the static blade 3 and the blade on the head side of the person to be hairdressed is the moving blade 6. Therefore, the stationary blade 3 is in a position where it can be easily seen by the user.However, as shown in FIGS. 2 to 3, the blade 2 serving as the stationary blade 3 has a concave shape like a diamond-shaped groove in the blade table A. 4 are provided. The recesses 4 have a width of 1 mm and are evenly spaced at 3 mm intervals. Each of the recesses 4 is provided at a depth of 0.8 mm from the blade back B as shown in FIGS. In other words, the recess is formed in a depth such that the thickness between the bottom of the recess 4 and the blade back B becomes substantially constant. Note that the cutting edge portion having a thickness of 0.8 mm or less has no concave portion (X in FIGS. 1 and 4). The scissors are manufactured by the following method.
まずステンレス材料を刃体形状に鍛造し、 その際、 静刃 3の刃表になる側 A には図 2〜図 5に示すように凹部 4も鍛造の際に同時形成しておく。 またこの 凹部 4は、 図 4に示すように研磨加工の前にあっては、 厚さ 3 . 3ミリの静刃 の半製品に 2 . 5ミリの深さに設けられ、 その際、 峰側 5部分だけは凹部 4を 設けずにおく。 この状態の半製品 2 ' を最終的な静刃の断面形状 Yとなるよう 研磨加工する。 このような静刃 3により鋏 1を形成すると、 ステンレス地に凹部による線画 で菱形格子の模様が映え、 デザイン的に優れる。 特に、 ステンレスの金属色の 上に無地の線画の描かれた状態となり、 この点でもデザイン的に優れる。 また、 鋏 1はその刃体の肉の一部が凹部 4の形成という形で落とされた状態となって 鋏 1が軽量化されている。 一般的な鉄の重量は、 1例として 6 0グラムである 力 これが 5〜6グラム程度軽減されても技術者にとっては大幅な負担軽減と なり、 本願発明によればこの様なことが可能になる。 更に、 鋏 1を研磨すると きには、 刃表 Aの刃先 7側 (図 1 ) を研磨するが、 凹部 4がある程度の深さを 有する実質的な凹部になっているので、 図 4の Xで示した刃先付近以外では菱 形格子の模様の消えることはない。 なお、 凹部の線画はこの例以外にも自由に形成してよく、 図 6〜図 1 1に示 すような模様が例示できる。 また、 このような幾何学模様に限らず、 図 1 2に 示すような具象的な図柄でもよく、 どのようであってもよい。 First, a stainless steel material is forged into a blade body shape. At this time, a concave portion 4 is simultaneously formed on the side A, which becomes the blade surface of the stationary blade 3, as shown in FIGS. Prior to polishing, the recess 4 is provided at a depth of 2.5 mm in a semi-finished 3.3 mm thick semi-finished product, as shown in FIG. Only the 5 parts are left without the recess 4. The semi-finished product 2 'in this state is adjusted to have the final static blade cross-sectional shape Y. Polishing. When the scissors 1 are formed with such static blades 3, a diamond-shaped lattice pattern is illuminated by a line drawing by a concave portion on a stainless steel ground, and the design is excellent. In particular, a solid line drawing is drawn on the stainless metal color, which is also excellent in design. In addition, the scissors 1 are in a state in which a part of the meat of the blade body is dropped in the form of the formation of the concave portion 4, and the scissors 1 are lightened. A typical iron weight is, for example, 60 g. Force Even if this is reduced by about 5 to 6 g, the burden on the technician is greatly reduced. According to the present invention, such a work is possible. Become. Further, when the scissors 1 are polished, the blade edge 7 side of the blade table A (FIG. 1) is polished. However, since the concave portion 4 is a substantial concave portion having a certain depth, X in FIG. The pattern of the diamond lattice does not disappear except in the vicinity of the cutting edge indicated by. In addition, the line drawing of the concave portion may be freely formed in addition to this example, and the patterns shown in FIGS. 6 to 11 can be exemplified. Further, the invention is not limited to such a geometric pattern, and may be a concrete pattern as shown in FIG. 12 or any other pattern.
また線画でなくてもよく、 刃表をハニカム構造なるように 6角形の凹部をそ のハニカム状に多数散在させてもよい。  Also, it is not necessary to be a line drawing, and a large number of hexagonal concave portions may be scattered in the honeycomb shape so that the blade surface has a honeycomb structure.
凹部の形成は鍛造に限らず、 刃体の鎵造の際に同時に凹部を形成するのでも よく、 或るいは、 先に刃体のみを製造しておき、 放電加工により凹部を形成し てもよく、 その他どの様な方法で凹部の形成をしてもよい。 The formation of the concave portion is not limited to forging, and the concave portion may be formed at the same time when the blade body is forged. Alternatively, only the blade body may be manufactured first, and the concave portion may be formed by electric discharge machining. The recess may be formed by any other method.
(実施例 2 ) ;次に上記の鋏 1にカラープラスチックによる充填部を設けた例を 説明する。 (Embodiment 2) Next, an example in which the scissors 1 are provided with a filling portion made of color plastic will be described.
即ちこの鋏 (図示せず) は、 ステンレスの刃体 2の刃表 Aに菱形の格子状に 凹部 4が凹設された点は実施例 1の図 1に示した鋏と同様ながら、 この凹部に 充填部が設けられている点が異なる。 充填部の設けられた鋏を実施例 1の図を 借用して説明すると、 図 1, 3, 6 , 7〜1 2の凹部 4の形状配置がそのまま 充填部の形状配置となる。 この充填部は、 主材料より軽量な材料としての着色 されたプラスチックが充填されたものであり、 凹部と同じ 1ミリ幅で 3ミリ間 隔に配置されている。 この鋏の製造方法をやはり実施例 1の図を借用して説明する。 In other words, the scissors (not shown) are similar to the scissors shown in FIG. A different point is that a filling section is provided. The scissors provided with the filling portion will be described with reference to the drawing of the first embodiment. The shape and arrangement of the recess 4 in FIGS. 1, 3, 6, and 7 to 12 are not changed. It becomes the shape arrangement of the filling part. This filling portion is filled with colored plastic as a lighter material than the main material, and is arranged at the same 1 mm width as the concave portion and at 3 mm intervals. The method of manufacturing the scissors will be described with reference to the drawing of the first embodiment.
ステンレス材料を刃体形状に鍛造し、 その際、 静刃 3の刃表 Aになる筒所に は図 2〜図 5に示したような凹部 4を同時形成し、 半製品 2 ' にしておく点は 実施例 1の鋏と同様である。 そしてこの状態の半製品 2 ' に有彩色のプラスチ ックを充填させ、 硬化した後に最終的な静刃の断面形状 Kとなるよう研磨加工 する。 このような静刃 3により鋏 1を形成すると、 ステンレス地に有彩色の菱形格 子の模様が映え、 デザイン的に優れる。 特に、 ステンレスとカラープラスチッ クとの色分け線がくっきりと明確に現れ、 この点でもデザイン的に優れる。 ま た遠目には静刃 3が着色されているように見える。 また、 実施例 1に示した鋏 1よりは充填部の分だけ重量が増すが、 ステンレスより軽量なプラスチックを 用いているので、 充填部のない従来のステンレスだけの鋏に比べると軽量化さ れている。 更に、 鋏 1を研磨するときに充填部 4が削られても、 新たな充填部 が現れるので、 菱形格子の模様の消えることはない。 なお、 刃表から凹設された実質的な凹部の断面形状は、 刃表の表面から凹部 の奥にかけてテーパー状であっても、 逆テーパー状であっても、 或いは、 凹部 の対面する側壁が平行となるように設けたものであってもよい。 逆テーパーに すれば充填部の抜け止め効果が得られる。 また凹部の側壁を凹凸面、 或いは粗 面にしておけばやはり抜け止め効果が得られる。 粗面にする方法としては、 凹 部を放電加工で設け、 その際、 被加工物である鋏材料の放電加工用電極に対す る相対的な移動速度を早くし、 あえて不完全な放電加工を行う方法がある。 また充填部は、 静刃 3に限らず、 動刃 6に設けてもよい。 以上により、 鋏のカラ一化、 或いは無彩色や他の金属色への着色などができ、 しかもこの様に着色された色彩が研磨によっても色の落ちない鋏として実現す る。 また、 充填する材料はプラスチックに限らず、 銅、 真鍮その他の、 ステン レスとは色彩の違いが明確な金属材料であってもよい。 更にこれら複数を混在 して用いてもよい。 A stainless steel material is forged into a blade shape. At this time, a recess 4 as shown in Figs. The points are the same as the scissors of Example 1. Then, the semi-finished product 2 ′ in this state is filled with chromatic plastic, and after being cured, it is polished so as to have a final sectional shape K of the static blade. When the scissors 1 are formed by such static blades 3, a chromatic rhombic grid pattern shines on stainless steel ground, and the design is excellent. In particular, the color-coded lines between stainless steel and color plastic appear clearly and clearly, and this is also an excellent design. At a distance, the stationary blade 3 appears to be colored. In addition, although the weight is increased by the filling portion compared to the scissors 1 shown in the first embodiment, since the plastic is lighter than stainless steel, the weight is reduced as compared with the conventional stainless scissors without the filling portion. ing. Furthermore, even if the filling portion 4 is shaved when the scissors 1 are polished, a new filling portion appears, so that the rhombic lattice pattern does not disappear. In addition, the cross-sectional shape of the substantial concave portion provided from the blade surface may be tapered from the surface of the blade surface to the depth of the concave portion, may be reverse tapered, or the side wall facing the concave portion may have a tapered shape. It may be provided so as to be parallel. By using a reverse taper, an effect of preventing the filled portion from coming off can be obtained. Also, if the side wall of the concave portion is made uneven or rough, a retaining effect can also be obtained. As a method for roughening the surface, a concave portion is provided by electric discharge machining, and at that time, the relative movement speed of the scissor material to be processed with respect to the electrode for electric discharge machining is increased, so that incomplete electric discharge machining is intentionally performed. There is a way to do it. The filling section is not limited to the stationary blade 3 but may be provided on the moving blade 6. As described above, the scissors can be colored or colored to an achromatic color or another metal color, and moreover, such colored colors can be realized as scissors that do not lose their color even by polishing. The material to be filled is not limited to plastic, but may be copper, brass, or any other metal material having a distinctive color difference from stainless steel. Further, these plural types may be mixed and used.
(実施例 3 ) ;図 1 3に示した鋏 1 1は、 ステンレス製の 2本の刃体 1 2, 1 2 を枢着して成り、 刃体 1 2の刃表から刃裏に貫通する穴部 1 3 a , 1 3 a, … が多数透設されている鋏 1 1である。 刃体 1 2に透設されている穴部 1 3 aの 周縁形状は、 十字星類似形状を成す四角模様の形状に形成され、 この様な穴部 1 3 aが刃体 2幅ほぼ中央を基端から先端にかけて直列模様状に配置されてい る。 穴部形状は上記に限らず自由に工夫してよく、 トランプのハート、 スぺ一 ド、 ダイヤ、 クローバなどの形状やその他であってよい。 この様な刃体 1 2の 2本を枢着してなる鋏 1 1は、 穴部 1 3 a内の空間に相 当する容積の総量分のステンレス重量だけ軽量化から図られている。 軽量化の 程度は穴部 1 3 aの大きさやその数を増減させて調整可能であり、 軽量化の無 断階調整を可能としている。 (Embodiment 3); Scissors 11 shown in FIG. 13 are composed of two stainless steel blades 12 and 12 pivotally connected to each other, and penetrate from the blade surface of blade 12 to the back of the blade. The scissors 11 have a large number of holes 13a, 13a, .... The peripheral shape of the hole 13 a penetrating through the blade 12 is formed in a square pattern shape that resembles a cross, and such a hole 13 a extends approximately at the center of the width of the blade 2. They are arranged in a serial pattern from the base end to the tip. The shape of the hole is not limited to the above, and may be freely devised, and may be a shape such as a heart of a playing card, a thread, a diamond, a clover, or the like.
