作業中にカッターやはさみなどが手元から離れ、すぐ見つけられなかったり、紐の先端が玉紐の中に入り込んだりこんがらがって掴みにくい事があった。
本発明は、以上の問題点を解決するためになされたものである。During the work, the cutter and scissors left the hand and could not be found immediately, or the tip of the string got into the ball string and was confused and difficult to grasp.
The present invention has been made to solve the above problems.

略コの字型の挟持体１であり、側面片８の端部から連設されている挟持片３と、他方の端部から連設された挟持片７からなっており、挟持片３の端部に紐通し穴４が設けられており、挟持片３及び挟持片７のいずれか又はそれぞれの端部には中空状の軸体５又は６が設けられており、側面片の略中央部分にカッター部９が設けられており、紐通し穴４とカッター部との間に保持部２を設ける。
以上の構成よりなる掴みしろが便利な玉巻きＰＰ紐カッター。It is a substantially U-shaped sandwiching body 1, which comprises a sandwiching piece 3 provided continuously from the end of the side piece 8 and a sandwiching piece 7 provided continuously from the other end. A string passing hole 4 is provided at the end, and a hollow shaft body 5 or 6 is provided at either or each of the holding piece 3 and the holding piece 7, and a substantially central portion of the side piece. A cutter unit 9 is provided, and the holding unit 2 is provided between the string passage hole 4 and the cutter unit.
A ball winding PP string cutter with the above-mentioned construction and convenient grip.

使用の際、ＰＰ紐の先端が適度な長さで常に出ているので簡単に掴め、カッターが一体型なので他の切断器具を用意したり探したりする煩わしさがなくなる。  During use, the tip of the PP string always comes out with a moderate length so that it can be easily grasped and the cutter is integrated so that there is no need to prepare or search for other cutting devices.

弾性素材からなる挟持体１であり、側面片８の端部から連設されている挟持片３と、他方の端部から連設された挟持片７からなっており、断片形状が略コの字状を形成している。挟持片３と挟持片７の端部にはそれぞれ軸体５、６が設けられており、軸体５は内部にビニール紐を通すことができるよう中空状となっている。また、挟持片３の軸体５を設ける側の端部には紐通し穴４が開いており、紐は軸体５の中空部を通って、挟持体１の外側へ抜ける構造となっている。なお、軸体５、６はそれぞれ長さ４０ミリメートル前後の筒状で、その軸体５と６の間隔はおよそ３５ミリメートル程度となっている。  A sandwiching body 1 made of an elastic material, comprising a sandwiching piece 3 provided continuously from the end of the side piece 8 and a sandwiching piece 7 provided continuously from the other end, and the fragment shape is substantially A letter shape is formed. Shaft bodies 5 and 6 are respectively provided at the end portions of the sandwiching piece 3 and the sandwiching piece 7, and the shaft body 5 is hollow so that a vinyl string can be passed therethrough. Further, a string passing hole 4 is opened at the end of the holding piece 3 on the side where the shaft body 5 is provided, and the string passes through the hollow portion of the shaft body 5 and is pulled out to the outside of the holding body 1. . The shaft bodies 5 and 6 each have a cylindrical shape with a length of about 40 millimeters, and the distance between the shaft bodies 5 and 6 is about 35 millimeters.

ここでいう弾性素材は、硬質ゴムやポリエチレン、ポリカーボネイトなど、変形しても復元する素材を示す。挟持体１すべてに使用することにより、挟持体１が開閉自在となる。または、弾性素材を側面片８にのみ使用し、挟持片３および挟持片７には合成樹脂を用いることも可能である。  The elastic material here refers to a material that can be restored even if it is deformed, such as hard rubber, polyethylene, and polycarbonate. By using it for all the clamping bodies 1, the clamping body 1 can be opened and closed freely. Alternatively, it is also possible to use an elastic material only for the side piece 8 and use a synthetic resin for the holding piece 3 and the holding piece 7.

前記軸体を、挟持片３および挟持片７にそれぞれ設ける他に、いずれかの挟持片に任意の長さの軸体を設ける手段も可能である（図６参照）。この時の長さとしては、玉紐を保持できる長さとし、つまり両挟持片間相当の長さが好ましい。  In addition to providing the shaft body on each of the sandwiching piece 3 and the sandwiching piece 7, means for providing a shaft body of any length on any of the sandwiching pieces is also possible (see FIG. 6). The length at this time is preferably a length that can hold the ball string, that is, a length corresponding to the distance between both sandwiched pieces.

側面片８の外側略中央にはカッター部９が設けられている。カッター部９は断面形状が略Ｌ字状を形成する枠体１０によって保持されており、カッター刃１１は下方、すなわち挟持片７側へ向いている。枠体１０と側面片８の間隔は安全上、作業者の指がカッター刃に触れないよう狭くなっている。  A cutter portion 9 is provided at the approximate center of the outside of the side piece 8. The cutter portion 9 is held by a frame body 10 having a substantially L-shaped cross section, and the cutter blade 11 faces downward, that is, toward the holding piece 7. The space between the frame 10 and the side piece 8 is narrow so that the operator's finger does not touch the cutter blade for safety.

保持部２は挟持片３に設けた紐通し穴４と、側面片８に設けたカッター部の間の挟持体１の外側に設けるのが好ましい。ここでいう保持部２は細い溝などで紐を挟み、紐が出たり戻ったりしない構造とする。  The holding part 2 is preferably provided outside the holding body 1 between the string passage hole 4 provided in the holding piece 3 and the cutter part provided in the side piece 8. The holding part 2 here has a structure in which a string is sandwiched between thin grooves and the string does not come out or return.

本発明を使用する時は、まず、紐の先端を軸体５の下側から紐通し穴４に通し、挟持片３の上面に出す。次に弾力性がある挟持体本体を広げて開閉させ、玉紐を軸体５、６の間に設置する（図３参照）。切断の際には紐を任意の長さまで引き出し、保持部２に当てがいながらカッター部９の下側より差し入れ、引き上げるようにしてカッター刃１１によって切断する（図４参照）。切断後の紐は保持部２の細い溝に挟まり固定され、カッター刃までの間の紐部分が数センチメートル残るので、再使用の際には掴み易い状態となっている。  When using the present invention, first, the tip of the string is passed from the lower side of the shaft body 5 through the string passing hole 4 and is put out on the upper surface of the holding piece 3. Next, the elastic clamping body main body is opened and opened, and the ball string is installed between the shaft bodies 5 and 6 (see FIG. 3). At the time of cutting, the string is pulled out to an arbitrary length, inserted from the lower side of the cutter unit 9 while being applied to the holding unit 2, and cut by the cutter blade 11 so as to be pulled up (see FIG. 4). The string after cutting is sandwiched and fixed in a narrow groove of the holding part 2, and the string part up to the cutter blade remains several centimeters, so that it is easy to grasp when reused.

玉紐を本体に設置するその他の手段としては、側面片８と挟持片３との連結部分にヒンジを設けるヒンジ方式（図５ａ参照）や側面片８を伸縮可能なスライド構造にするスライド方式（図５ｂ参照）、または側面片８の上部に回転軸を設け挟持片３を水平方向に回転させる回転方式（図５ｃ参照）なども考えられる。  Other means for installing the ball strap on the main body include a hinge system (see FIG. 5a) in which a hinge is provided at the connecting portion between the side piece 8 and the sandwiching piece 3, and a slide system in which the side piece 8 can be expanded and contracted (see FIG. A rotation method (see FIG. 5c) in which a rotation shaft is provided on the upper portion of the side piece 8 and the sandwiching piece 3 is rotated in the horizontal direction is also conceivable.

挟持体１、保持部２、挟持片３、紐通し穴４、軸体５、軸体６、挟持片７、側面片８、カッター部９、枠体１０、カッター刃１１  Clamping body 1, holding part 2, clamping piece 3, string passage hole 4, shaft body 5, shaft body 6, clamping piece 7, side piece 8, cutter part 9, frame body 10, cutter blade 11
