Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、カッターに係り、詳しくはダンボールや厚紙等を容易に切断できる カッターに関するものである。 The present invention relates to a cutter, and more particularly to a cutter that can easily cut cardboard, cardboard, and the like.

【0002】[0002]

【従来の技術】[Prior art]

従来から、小学校・幼稚園等の工作の時間で幼児・児童がダンボールや発泡ス チロール等を切断する場合、カッターナイフまたは鋏が使用されている。 Conventionally, cutter knives or scissors have been used when infants and children cut corrugated cardboard and Styrofoam at the time of construction at elementary schools and kindergartens.

【0003】[0003]

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

ところが、鋏ではダンボールや発泡スチロール等を裁断する場合、幼児・児童 では大きな力が必要なため不向きである。一方、カッターナイフは先が尖ってい るため幼児・児童には安心して持たせられない問題がある。また、カッターナイ フは刃が鋭利なため力を加えた以上に刃が喰い込み切れ過ぎる危険がある。よっ て安全で能率よく切断できるカッターの開発が望まれている。 However, scissors are not suitable for cutting cardboard or Styrofoam because infants and children require a great deal of force. On the other hand, since the cutter knife has a sharp tip, there is a problem that infants and children cannot safely hold it. In addition, since the blade of the cutter knife is sharp, there is a danger that the blade will bite more than the force is applied and it will be overcut. Therefore, it is desired to develop a cutter that is safe and can cut efficiently.

【0004】[0004]

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

上記問題点を解決するために本考案は、刀身の背部が刃部にかけて両側面を刃 部側が薄くなるようにテーパー状に形成し、前記刀身の先端部の少なくとも刃部 側をア−ル状に形成して前記ア−ル状部から刃部には連続的に鋸刃を設けたこと を特徴とするカッターを要旨とするものである。 In order to solve the above-mentioned problems, the present invention forms the back of the blade into a taper shape so that both sides of the blade extend toward the blade so that the blade is thinner on the blade side, and at least the blade side of the tip of the blade is arcuate. A gist of the present invention is a cutter characterized in that a saw blade is continuously formed on the blade portion from the above-mentioned al-shaped portion.

【0005】[0005]

【作用】[Action]

このように構成された本考案は、ダンボールや発泡スチロール等の軟らかく、 かつ切断した後に刀身が通ってできたすきまを埋めるように伸びる弾性をもつ材 料を本考案のカッターにより切断するとき、鋸刃状に形成された刃部のため刀身 が吸着されることはない。 The present invention thus constructed has a saw blade when cutting a soft material such as corrugated cardboard or styrofoam, which has elasticity that extends so as to fill the gap formed by the blade after cutting with the cutter of the present invention. The blade is shaped like a blade, so the blade is not adsorbed.

【0006】 又、先端部のア−ル状部に鋸刃があるため、ダンボール等を途中から切込み又 は切り抜くときにも簡単に切込み、切り抜きを行うことができる。 さらに、刃部が鋸刃となっているため、刃が必要以上にダンボール等に喰い込 み過ぎるということもない。Further, since there is a saw blade in the arm-shaped portion at the tip end, it is possible to easily perform cutting and cutting even when cutting or cutting cardboard or the like from the middle. Furthermore, since the blade portion is a saw blade, the blade does not over-embed into a cardboard or the like more than necessary.

【実施例】【Example】

以下、本考案を具体化した第一実施例を図1〜図3に従って説明する。 図1に示すように、カッター1は柄2と刀身3とから構成されている。 A first embodiment embodying the present invention will be described below with reference to FIGS. As shown in FIG. 1, the cutter 1 includes a handle 2 and a blade 3.

【0008】 刀身3は背部4と刃部5とが図1に示すように大部分が長手方向に亘って略平 行に形成され、この実施例では背部4と刃部5間は20mm以下として刃幅を狭 くしている。刀身3の先端部はア−ル状に形成され、又、刀身3は背部4から刃 部5にかけて図3(a)に示すように刃部5側が薄くなるように両側面がテーパ ー状に形成されている。なお、この実施例では背部4側の1/3の両側面は、平 行に形成され、残りの両側面の2/3がテーパー状となっている。そして、前記 1/3の平行部分の厚みは0.4mm〜1.0mmの間としている。前記刃部5 は、先端のア−ル状部を含んで鋸刃が形成されている。As shown in FIG. 1, most of the blade 3 of the blade 3 has a back portion 4 and a blade portion 5 which are formed in a substantially flat shape in the longitudinal direction. In this embodiment, the distance between the back portion 4 and the blade portion 5 is 20 mm or less. The blade width is narrow. The tip of the blade 3 is formed in an arc shape, and the blade 3 has a tapered shape on both sides from the back 4 to the blade 5 so that the blade 5 becomes thinner as shown in FIG. 3 (a). Has been formed. In this embodiment, 1/3 of both side surfaces on the back 4 side are formed in a flat shape, and 2/3 of the remaining both side surfaces are tapered. The thickness of the 1/3 parallel portion is between 0.4 mm and 1.0 mm. The blade portion 5 is formed with a saw blade including the tip end of the arc-shaped portion.

【0009】 本実施例の鋸刃は、隣接する刃と刃との間を2mm以下のものとし、細かい鋸 刃となっている。 次に前記のように構成されたカッター1の作用を説明する。The saw blade of the present embodiment is a fine saw blade having a distance between adjacent blades of 2 mm or less. Next, the operation of the cutter 1 configured as described above will be described.

【0010】 ダンボールや発泡スチロール等をカッター1にて切断するときの引いて切り一 戻ししてまた引いて切る反復運動の中の一戻しする動作において、刃部5が鋸刃 状に形成されているため、刀身3が被切断面に吸着されることはない。また、こ のカッター1にてダンボール等に途中から切込みを入れたり、切り抜く場合は、 先端のア−ル状部の鋸刃部分から切断を開始する。このことにより容易にダンボ ール等に対して途中から切込み、切断することができる。先端部はア−ル状とな っていて、刃の厚さも0.4mm〜1.0mmと薄いため柔軟性を得ることがで き、へらとしても使用できる。また、刃部5の鋸刃はカッターナイフの刃のよう に鋭利でないため、安全であり児童にも安心して持たせられる。また加えた力以 上に刃部5が被切断材に喰い込み切れ過ぎる心配もない。さらに、この実施例で は背部4と刃部5間は最大20mm程度として、両部4、5はほぼ平行となって いるため、ダンボール等を湾曲して切り抜いたり、曲線に切断することも容易に できる。The blade portion 5 is formed in a saw-tooth shape in the reciprocating motion of the repetitive motion of pulling, cutting and returning once and then cutting by cutting the cardboard, styrofoam, etc. with the cutter 1. Therefore, the blade 3 is not adsorbed on the cut surface. When the cutter 1 is used to make or cut a cardboard or the like from the middle, the cutting is started from the saw-tooth portion of the tip end of the arc-shaped portion. As a result, it is possible to easily cut and cut the cardboard or the like from the middle. The tip has an arcuate shape and the thickness of the blade is as thin as 0.4 mm to 1.0 mm, so that flexibility can be obtained and it can also be used as a spatula. Further, the saw blade of the blade portion 5 is not as sharp as the blade of a cutter knife, so it is safe and can be held safely by children. Further, there is no fear that the blade 5 will bite into the material to be cut and cut too much beyond the applied force. Further, in this embodiment, the distance between the back portion 4 and the blade portion 5 is about 20 mm at the maximum, and since both portions 4 and 5 are substantially parallel, it is easy to cut out a cardboard or the like by curving or cutting into a curved line. You can

【0011】 なお、本考案は前記実施例の構成に限定されるものではなく、例えば図3(b )のようにテーパー部を刃部5から背部4まで刀身3の両側全体に設けてもよい 。さらに、図3(c)に示すように、テ−パ−部を刀身3の先端両側に設け、か つ片面のテ−パ−部に連続して波状の鋸刃を設けてもよい。また、図3(c)の 両面のテ−パ−部に連続して波状の鋸刃を設けてもよい。また、この考案の趣旨 から逸脱しない範囲で各部の構成を任意に変更して具体化することも可能である 。The present invention is not limited to the configuration of the above embodiment, and for example, as shown in FIG. 3B, tapered portions may be provided on the entire sides of the blade 3 from the blade portion 5 to the back portion 4. . Further, as shown in FIG. 3 (c), taper portions may be provided on both sides of the tip of the blade 3, and a wavy saw blade may be continuously provided on the taper portion on one side. Further, wavy saw blades may be continuously provided on the taper portions on both sides of FIG. Further, the configuration of each part can be arbitrarily modified and embodied without departing from the spirit of the invention.

【考案の効果】[Effect of device]

以上詳述したように本考案によれば、ダンボールや発泡スチロール等の軟らか い材を切断する際の引いて切り一戻ししてまた引いて切る反復運動の中の一戻し する動作において、カッターナイフほど刃が鋭利でないため力を加えた以上に刃 が喰い込み切れ過ぎる危険もなく、かつ手を切るという心配もなく所期の目標が 達成できる。 As described above in detail, according to the present invention, when cutting soft materials such as corrugated cardboard and styrofoam, pulling, cutting and returning, and then pulling and cutting again Since the blade is not sharp, there is no danger that the blade will bite too much more than when force is applied, and there is no worry of cutting the hand, and the desired goal can be achieved.
