Description

ここに開示する発明は、デザインナイフ、特に、プラスチックモデルの組み立てに適した模型用のデザインナイフに関する。   The present invention disclosed herein relates to a design knife, and more particularly to a design knife for a model suitable for assembling a plastic model.

プラスチックモデル(プラスチック製の組み立て模型玩具)の組み立てにあたって各パーツを加工する際に、ゲートの切断跡をきれいに処理したり、細部を好みに加工したりするために、特許文献1に開示されるようなデザインナイフ(文献中ではペン型ナイフ)が使用される。デザインナイフは模型加工の様々な用途で使用されるが(例えば非特許文献1参照)、ペン型であるからその作業態様は、利き手でデザインナイフを持ち、他方の手でパーツ等を押さえつつ加工を行うというものになる。この作業態様の故に、力の加減を誤ると、パーツ等を押さえている方の手を傷つける危険がある。特に、ゲートの切断跡をきれいに処理する場合、最初にランナーとの間のゲートを他の適切な工具で切断してパーツを切り離し、そして、切り離したパーツに残ったゲートの切断跡をデザインナイフできれいに仕上げる作業を行うが、パーツが小さいと、パーツを持った手の指を傷つけやすい。   As disclosed in Patent Document 1, in order to cleanly process a cut mark of a gate or to process a detail as desired when processing each part in assembling a plastic model (plastic model toy). A design knife (pen-type knife in the literature) is used. Design knives are used in various applications for model processing (see, for example, Non-Patent Document 1), but since they are pen-shaped, they work while holding the design knife with your dominant hand and holding parts etc. with your other hand. Will be done. Due to this work mode, if the force is erroneously adjusted, there is a risk of injuring the hand of the person who holds the parts or the like. Especially when treating the cut traces of the gate cleanly, first cut the gate between the runner with another suitable tool to separate the parts, and then use the design knife to remove the cut traces of the gate left on the separated parts. The work is done neatly, but if the parts are small, it is easy to damage the fingers of the hand holding the parts.

また、細長い銃身のある火器やアンテナなどの細いパーツの場合には、ランナーから切り離すときに最初から刃の薄いデザインナイフを使用したいところであるが、ペン型のデザインナイフでは手元が安定せず、パーツを損傷したり、指を傷つけたりすることがある。   Also, in the case of thin parts such as firearms and antennas with an elongated barrel, I would like to use a design knife with a thin blade from the beginning when disconnecting from the runner, but with a pen type design knife the hand is not stable, so parts May be damaged or your finger may be injured.

https://love-p.jp/tools-design-nife,ラブ・プラ,「プラモデル制作で使用するデザインナイフ・カッターナイフの解説」,2018年9月14日検索https://love-p.jp/tools-design-nife, love plastic, “Explanation of design knife and cutter knife used in plastic model production”, searched September 14, 2018

デザインナイフの切れ味は鋭くて、きれいにゲートを切断し処理するには最適なので、上記の点を考慮した安定性、安全性の高いデザインナイフがあれば好ましい。   Since the design knife has a sharp cutting edge and is most suitable for cutting and processing the gate cleanly, it is preferable to have a design knife with high stability and safety in consideration of the above points.

この課題を解決するべく本発明は、先端に刃を保持する刃保持部を備えた把持体からなるデザインナイフについて、把持体にまな板刃体を枢着することを提案する。当該まな板刃体は、把持体との枢着軸を支点として作用点部と力点部をもち、その作用点部に、刃保持部に保持された刃と対向するまな板刃を備える。そして、力点部の操作で作用点部のまな板刃は、保持された刃に対し回動させることが可能とされている。   In order to solve this problem, the present invention proposes to pivotally attach a cutting board blade body to a grip body for a design knife comprising a grip body having a blade holding portion for holding a blade at a tip thereof. The cutting board blade body has an action point portion and a force point portion with a pivotal axis with respect to the gripping body as a fulcrum, and the action point portion is provided with a cutting board blade facing the blade held by the blade holding portion. The cutting board blade at the action point portion can be rotated with respect to the held blade by operating the force point portion.

まな板刃体の長さは、把持体よりも短くするのがよく、好ましくは、まな板刃体の力点部の長さを、刃保持部を除いた把持体の長さの半分以下とするのがよい。この態様により、把持体を持った手の親指で力点部を楽に操作することができる。またこの場合、把持体を人の手で持つのに適した長さにできる一方、短い力点部は支点−力点の距離を短くすることで、作用点部にあるまな板刃を介して刃へ過大な力がかからないようにすることが可能である。   The length of the cutting board blade is preferably shorter than the gripping body, and preferably, the length of the force point portion of the cutting board blade body is half or less of the length of the gripping body excluding the blade holding portion. Good. According to this aspect, it is possible to easily operate the force application point with the thumb of the hand holding the grip body. Further, in this case, the gripping body can be made to have a length suitable for being held by a human hand, while the short force point portion is shortened by the distance between the fulcrum and the force point, so that the blade is excessively moved to the blade through the cutting board blade at the action point portion. It is possible to avoid applying excessive force.

このまな板刃体を短くする態様についてはさらに、その力点部が短いことを利用して、まな板刃体を閉状態でロックする安全装置を設けることができる。すなわち、把持体にレールを形成し、該レールに沿って前後進するスライド体を設け、該スライド体が、前進位置でまな板刃体力点部の後端に係止し、後退位置で該係止を解くように作用する、安全装置である。   With regard to the aspect of shortening the cutting board blade body, a safety device for locking the cutting board blade body in a closed state can be provided by utilizing the fact that the force point portion is short. That is, a rail is formed on the grip body, and a slide body that moves forward and backward along the rail is provided. The slide body locks at the rear end of the cutting board blade force point portion at the forward position and at the retracted position. It is a safety device that acts to solve.

本発明に係るデザインナイフは、まな板刃をゲートにあてがって押さえつつ、反対側から刃保持部の刃でゲートを挟みながら切断することができるので、従来のデザインナイフに比べて格段に使用時の安定性が良く且つ安全である。   The design knife according to the present invention can be cut while sandwiching the gate with the blade of the blade holding portion from the opposite side while pressing and holding the cutting board blade against the gate, so that when compared to conventional design knives, It is stable and safe.

本発明に係るデザインナイフの実施形態を、図面を参照して説明する。   An embodiment of a design knife according to the present invention will be described with reference to the drawings.

デザインナイフ1は、細長い概略長方形の把持体10からなり、この把持体10の先端に、把持体10の軸から少し(数ミリ〜十数ミリ)オフセットさせて刃保持部11が設けられている(図2参照)。すなわち、把持体10の先端部分は、軸方向に対し斜めに延伸させてあり、この斜め延伸部分に刃保持部11が設けられる。刃保持部11は、デザインナイフの刃12を着脱可能に保持する。すなわち、切れ味が悪くなったり刃先が欠けた場合に刃12は交換可能である。このために刃保持部11は、刃12の外形に整合させて凹設した嵌入凹部11aと、嵌入凹部11aを覆うようにして螺子11bにより固定され、嵌入凹部11aに嵌め入れられた刃12を押さえ付ける押圧片11cとからなる。嵌入凹部11aの形状に従って刃12は、刃先が把持体10の軸線に平行となるようにして保持される。   The design knife 1 is composed of an elongated, substantially rectangular grip body 10, and a blade holding portion 11 is provided at the tip of the grip body 10 with a slight offset (several millimeters to tens of millimeters) from the axis of the grip body 10. (See Figure 2). That is, the tip portion of the grip body 10 is stretched obliquely with respect to the axial direction, and the blade holding portion 11 is provided in this diagonal stretched portion. The blade holder 11 detachably holds the blade 12 of the design knife. That is, the blade 12 can be replaced when it becomes less sharp or the cutting edge is chipped. For this reason, the blade holding portion 11 is fixed by a fitting recess 11a that is recessed in conformity with the outer shape of the blade 12 and a screw 11b so as to cover the fitting recess 11a, and the blade 12 fitted in the fitting recess 11a is fixed. It is composed of a pressing piece 11c to be pressed down. According to the shape of the fitting recess 11a, the blade 12 is held so that the blade tip is parallel to the axis of the grip body 10.

把持体10には、まな板刃体20が、枢着軸となる枢着螺子30で回動可能に枢着される。枢着軸をなす枢着螺子30は、図2に示す把持体10の先端部分に設けた枢着軸孔13及びまな板刃体20の枢着軸孔21を貫通し、裏側で六角ナット31により固定される。把持体10には、ナット31を回転しないように受け入れる受容凹部14(図6参照)が形成されている。受容凹部14を形成する以外にも、ナット31自体を緩み止めナットとしたりする、周知の技術を利用してよい。   A cutting board blade body 20 is pivotally attached to the grip body 10 by means of a pivot screw 30 serving as a pivot shaft. The pivot screw 30 forming the pivot shaft penetrates the pivot shaft hole 13 provided in the tip portion of the grip body 10 and the pivot shaft hole 21 of the cutting board blade body 20 shown in FIG. Fixed. The grip body 10 is formed with a receiving recess 14 (see FIG. 6) that receives the nut 31 so as not to rotate. In addition to forming the receiving recess 14, a well-known technique in which the nut 31 itself is used as a locking nut may be used.

まな板刃体20は、枢着螺子30による枢着軸を支点としたテコの原理で作用点となる作用点部22と、力点となる力点部23とを有する。その作用点部22に、刃保持部11に保持された刃12と対向するまな板刃24を有する。まな板刃24は、図3に示すようにまな板刃体20の閉状態で、刃保持部11に保持された刃12の刃先に当接する(図4も参照)。まな板刃24は、刃12との当接端面24aが刃12よりも厚く形成され、刃12の刃先を受け止める形状にしてある。切断面をきれいにするには、当接端面24aの厚さはできるだけ薄いほうがよい。   The cutting board blade body 20 has an action point portion 22 which is an action point according to the principle of leverage with a pivot axis of the pivot screw 30 as a fulcrum, and a force point portion 23 which is a force point. The action point portion 22 has a cutting board blade 24 facing the blade 12 held by the blade holding portion 11. The cutting board blade 24 abuts on the cutting edge of the blade 12 held by the blade holding portion 11 when the cutting board blade body 20 is closed as shown in FIG. 3 (see also FIG. 4). The cutting blade 24 has a contact end surface 24a with the blade 12 formed to be thicker than the blade 12, and has a shape for receiving the cutting edge of the blade 12. In order to clean the cut surface, the contact end surface 24a should be as thin as possible.

まな板刃体20において、力点部23は、作用点部22に対してオフセット(数ミリ〜十数ミリ)させて設けられている。すなわち、枢着軸孔21が位置する作用点部22の端から延びた延長部25が形成されており、この延長部25の先に、図3の閉状態で把持体10の軸と平行になる軸をもった概略長方形の力点部23が形成される。延長部25は、上述した把持体10の斜めに延伸した先端部分とは逆の方向に延長されるので、力点部23は閉状態において把持体10と平行になることができる。   In the cutting board blade body 20, the force point portion 23 is provided offset (several millimeters to ten and several millimeters) from the action point portion 22. That is, an extension 25 extending from the end of the action point portion 22 in which the pivot shaft hole 21 is located is formed, and at the end of this extension 25, in parallel with the axis of the grip body 10 in the closed state of FIG. An approximately rectangular force point portion 23 having an axis is formed. Since the extension portion 25 is extended in the direction opposite to the above-mentioned obliquely extending tip portion of the grip body 10, the force application portion 23 can be parallel to the grip body 10 in the closed state.

本実施形態の把持体10及びまな板刃体20は射出成形による樹脂製とし、強度を得るため表面に適宜リブを形成してある。すなわち、把持体10及びまな板刃体20は大量生産可能であり、デザインナイフ1の低価格化に大きく貢献する。高精度が要求されないので、把持体10及びまな板刃体20は、樹脂製以外にも、鉄系材料のプレス加工品などとすることもできる。もちろん、好みによっては工具鋼からの削り出しとしたりしてもよい。   The gripping body 10 and the cutting board blade body 20 of the present embodiment are made of resin by injection molding, and ribs are appropriately formed on the surface to obtain strength. That is, the grasping body 10 and the cutting board blade body 20 can be mass-produced, which greatly contributes to the cost reduction of the design knife 1. Since high accuracy is not required, the gripping body 10 and the cutting board blade body 20 can be made of a press-formed product of an iron-based material, instead of being made of resin. Of course, it may be machined from tool steel, if desired.

本実施形態の場合、まな板刃体20の長さは、把持体10の長さよりも短くしてある。好適には、刃保持部11を除いた把持体10の長さ(枢着軸30から後端までの長さ)に対し、まな板刃体20の力点部23の長さを半分以下にする。把持体10は、人の手で持つのに適した長さすることができる一方、これより短いまな板刃体20の力点部23は、支点−力点の距離を短くすることで、作用点のまな板刃24に対向する刃12に過大な力がかからないように工夫され、また、把持体10を持った手の親指で特に刃を閉じる方向へ操作することが容易になる。   In the case of this embodiment, the length of the cutting board blade body 20 is shorter than the length of the grip body 10. Preferably, the length of the power point portion 23 of the cutting board blade body 20 is half or less than the length of the grip body 10 (the length from the pivot shaft 30 to the rear end) excluding the blade holding portion 11. The gripping body 10 can have a length suitable for being held by a human hand, while the power point portion 23 of the cutting board blade body 20 shorter than this can shorten the distance between the fulcrum and the power point to cut the work point. The blade 12 facing the blade 24 is devised so that an excessive force is not applied, and the thumb of the hand holding the grip 10 makes it easy to operate especially in the direction of closing the blade.

まな板刃体20は、不用意に開くことのないように、安全装置により閉状態でロックできる(図3)。安全装置は、把持体10においてまな板刃体20の力点部23が届かない部位に形成したレール15と、該レール15と係合し且つ該レール15に沿って前後進するスライド体40とから構成される。スライド体40は、先端の凸部41が図3の前進位置で、閉状態にあるまな板刃体20の力点部23の後端に突設された2つの爪26の間へ係止し、まな板刃体20を閉状態でロックする。この前進位置から、ロック解除すべく図5Aに示すようにスライド体40を矢示A方向へスライドさせ、後退位置まで後退させると、図5Bに示すとおり、凸部41と爪26との係止が解除されてまな板刃体20が解放され、矢示B方向へ回動させて開状態にすることができる。   The cutting board blade body 20 can be locked in a closed state by a safety device so as to prevent accidental opening (FIG. 3). The safety device is composed of a rail 15 formed at a portion of the gripping body 10 that the power point portion 23 of the cutting board blade body 20 does not reach, and a slide body 40 that engages with the rail 15 and moves forward and backward along the rail 15. To be done. In the slide body 40, the protruding portion 41 at the tip is locked between the two claws 26 projecting from the rear end of the force point portion 23 of the cutting board blade body 20 in the closed state at the forward position of FIG. The blade body 20 is locked in the closed state. When the slide body 40 is slid in the direction of arrow A as shown in FIG. 5A from this forward position to unlock, and is retracted to the retracted position, the protrusion 41 and the claw 26 are locked as shown in FIG. 5B. Is released and the cutting board blade body 20 is released, and the cutting board blade body 20 can be rotated in the direction of arrow B to be in the open state.

図6及び図7に、変形例を示す。この例は、まな板刃体20を開状態へ付勢する付勢装置として、バネ50を把持体10に組み込んだ形態である。なお、把持体10に付勢装置を組み込む例を示すが、同様の形態でまな板刃体20の方に付勢装置を組み込むことも可能である。図示の例において、把持体10には、バネ50を収容する収容凹部16が形成されており、この収容凹部16内に、軸支ピン17が突設されている。バネ50には、樹脂製のU字形バネ、あるいは金属製のトーションバネや板バネ等を使用することができ、その基部51にある軸支孔を軸支ピン17に嵌め込むことで収容凹部16に装着される。基部51から延びる2つの腕部52,53のうちの一方の腕部52が収容凹部16の側壁に当接し、他方の腕部53が屈曲して収容凹部16から突出し、この突出した腕部53がまな板刃体20の力点部23に当接して、把持体10から開く方向へ付勢する。付勢装置は、この他にも、把手体10とまな板刃体20との間に挿入されるコイルスプリングなどとすることもできる。   Modified examples are shown in FIGS. 6 and 7. In this example, a spring 50 is incorporated in the grip body 10 as an urging device for urging the cutting board blade body 20 to an open state. Although an example in which the biasing device is incorporated in the grip body 10 is shown, the biasing device can be incorporated in the chopping board blade body 20 in a similar manner. In the illustrated example, the holding body 10 is formed with an accommodating recess 16 for accommodating the spring 50, and in this accommodating recess 16, a pivot pin 17 is provided in a protruding manner. A U-shaped spring made of resin, a torsion spring made of metal, a leaf spring, or the like can be used as the spring 50. By fitting the shaft support hole in the base 51 of the spring support pin 17 into the housing recess 16 Be attached to. One of the two arm portions 52 and 53 extending from the base portion 51 abuts on the side wall of the housing recess 16, the other arm 53 bends and projects from the housing recess 16, and the protruding arm portion 53 It abuts against the power point portion 23 of the cutting board blade body 20 and urges it in the opening direction from the grip body 10. In addition to this, the biasing device may be a coil spring or the like inserted between the handle body 10 and the cutting board blade body 20.

上記実施形態に係るデザインナイフ1は、まな板刃体20を外して使用することも可能であり、この場合は従来型の普通のデザインナイフのように使用することができる。この形態は、比較的怪我をし難い、パーツを自分好みに加工するときなどに利用可能である。   The design knife 1 according to the above-described embodiment can be used by removing the cutting board blade body 20, and in this case, it can be used like a conventional conventional design knife. This form is relatively hard to be injured and can be used when processing parts to your liking.

ここに開示したデザインナイフ1は、一例として、他の工具でゲートを切断してランナーから切り離したパーツにおいてそのゲートの切断跡をきれいに仕上げる処理を行う場合に、把持体10を手に持ち、開状態にしたまな板刃体20の作用点部22にあるまな板刃24をゲートの切断跡にあてがってまな板刃24と刃12で切断跡を挟み、そして、力点部23を親指で押す操作で作業することができる。ペン型の従来型デザインナイフと違ってまな板刃24をあてがうことができるので、作業時の手元が安定し(刃12の移動距離も制限され)、ペン型のように力の入れ具合で不用意に刃が滑ってパーツを持った手を傷つけることもなく、安全である。   As an example, the design knife 1 disclosed herein holds the gripping body 10 in the hand and opens the gripping body 10 when carrying out a process of cutting the gate with another tool to finish the cut trace of the gate cleanly in the part separated from the runner. Apply the cutting board blade 24 at the action point portion 22 of the cutting board blade body 20 in the state to the cutting trace of the gate, sandwich the cutting trace with the cutting board blade 24 and the blade 12, and press the force point portion 23 with the thumb be able to. Unlike the conventional pen type design knife, the cutting board blade 24 can be applied, so the hand at work is stable (the movement distance of the blade 12 is also limited) and it is not prepared with the force like the pen type. It's safe because the blade doesn't slip and hurt the hand holding the parts.

以上、好適な実施形態を説明したが、例えば把手体10に対するまな板刃体20の長さなど、細部については、使用目的等に応じて適宜変更を加えることができる。   Although the preferred embodiment has been described above, the details such as the length of the cutting board blade 20 with respect to the handle 10 can be appropriately changed according to the purpose of use.
