Description

本発明は、カッターナイフに装着のカッター刃を使って、はさみ圧切りできるカッターナイフに関するものである。  The present invention relates to a cutter knife capable of cutting off with scissors using a cutter blade attached to the cutter knife.

従来、カッターナイフの用途はカッター刃の各刃片の尖端刃を使って物の切り離しに使い、装着のカッター刃の刃片を順次折り捨てることによって切れ具合を保持する切断道具のカッターナイフがあった。
特開平５−３０５１８７号公報 Conventionally, cutter knives have been used as cutting knives, which are used for cutting objects with the cutting edge of each blade of the cutter blade, and keep the cutting condition by sequentially breaking the blades of the attached cutter blade. It was.
JP-A-5-305187

解決しようとする問題点は、次のような欠点があった。
カッターナイフの使われ方が、カッター刃の各刃片の尖端刃のみに集中するため、切れ具合が悪くなれば順次折り捨てられ、尖端刃以外の大部分の刃部が有用に使われず、これを有用に使える機能を持っていないという欠点があった。
本発明は、以上の問題点を解決し、あまり使われない部分の刃を有用に使って、はさみ圧切りできるようになされたものである。The problem to be solved has the following drawbacks.
Because the way the cutter knife is used concentrates only on the pointed edge of each blade of the cutter blade, if the cutting condition worsens, it will be broken down sequentially, and most of the blade parts other than the pointed edge will not be used effectively. There was a drawback of not having a function that can be used effectively.
The present invention has been made to solve the above problems and to enable scissor pressure cutting by effectively using a part of a blade that is not frequently used.

刃ホルダー（４）を被う握体（１）にピン孔（２）を設け、レバーピン（１０）で装着のレバー（８）を設け、そのレバー（８）にバネ（９）、圧切り部（１１）、下端部（１２）を設け、圧切り部（１１）はカッター刃（１９）の複数の刃片（２０）の刃部（２１）の尖端刃（２２）部分に接圧しないように設ける。握体（１）にスライド可能なセレクター孔（３）を設け、セレクターピン（１４）で装着のセレクター（１３）を設け、そのセレクター（１３）に上端部（１５）を設ける。カッター刃（１９）を覆う刃ホルダー（４）には刃片（２０）と同ピッチの複数の凹部（７）と、刃ホルダー（４）の刃側部（５）に刃露出部（６）を設ける。ロックバネ（１８）とカッター刃（１９）を取り替える刃替凸部（１７）を備えたスライド（１６）を有する。
本発明は、以上の構成よりなるはさみ圧切り機構があるカッターナイフである。A pin hole (2) is provided in the grip body (1) that covers the blade holder (4), a lever (8) is provided by the lever pin (10), a spring (9), and a pressure cutting portion are provided on the lever (8). (11) A lower end portion (12) is provided, and the pressure cut portion (11) does not contact the pointed blade (22) portion of the blade portion (21) of the plurality of blade pieces (20) of the cutter blade (19). Provided. A slidable selector hole (3) is provided in the grip (1), a selector (13) is provided by a selector pin (14), and an upper end (15) is provided in the selector (13). The blade holder (4) covering the cutter blade (19) has a plurality of recesses (7) having the same pitch as the blade piece (20), and the blade exposed portion (6) on the blade side portion (5) of the blade holder (4). Is provided. It has a slide (16) provided with a blade replacement projection (17) for replacing the lock spring (18) and the cutter blade (19).
The present invention is a cutter knife having a scissor pressure cutting mechanism configured as described above.

本発明のはさみ圧切り機能を持つカッターナイフは、従来のカッターナイフの切れ具合の要となるカッター刃の各刃片の尖端刃をさけて、ほとんど使われず折り捨ててしまう刃部を使って紐などの切断、電線などの被覆の切り離しができるので、カッター刃の刃部全体を有用に利用することができる利点がある。  The cutter knife having the scissor pressure cutting function according to the present invention is a string that uses a blade part that is rarely used and smashes away from the sharp edge of each blade of the cutter blade, which is the key to cutting of a conventional cutter knife. Therefore, there is an advantage that the entire blade part of the cutter blade can be used effectively.

主に、尖端刃を使用する従来のカッターナイフの機能に、はさみ圧切り機能を加えるという目的を、カッターナイフに装着のカッター刃の尖端刃部分以外の刃部を利用し、使用する刃部を分担させて、刃部全体を有用に使用するようにして実現した。  The purpose of adding scissors pressure cutting function to the function of the conventional cutter knife that uses a pointed blade is to use the blade part other than the pointed edge part of the cutter blade attached to the cutter knife, and to use the blade part to be used It was made to share and the whole blade part was used effectively.

図１は、本発明の１実施例のはさみ圧切り使用時状態の正面図であって、図３は、同様の正面図の部分断面図である。図１、図３では、カッター刃が刃ホルダーから外へでているが、はさみ圧切り使用時においても、カッター刃は前端から順次使われるため、通常は、カッター刃は刃ホルダーから外へは出ない。又、図２は、本発明の１実施例の従来のカッターナイフ使用時状態の正面図であって、図４は、同様の正面図の部分断面図である。  FIG. 1 is a front view of the embodiment of the present invention when using scissor pressure cutting, and FIG. 3 is a partial sectional view of the same front view. In Fig. 1 and Fig. 3, the cutter blade is out of the blade holder. However, even when using scissor pressure cutting, the cutter blade is normally used from the front end. Does not appear. 2 is a front view of the embodiment of the present invention when the conventional cutter knife is used, and FIG. 4 is a partial sectional view of the same front view.

以下、本発明の実施の形態について説明する。
（イ）プラスチックなどの材質からなる握体（１）にピン孔（２）を設け、金属などの材質のレバーピン（１０）で装着のプラスチックなどの材質のレバー（８）を設ける。
