Abstract
Description
この発明は、穿孔刃の駆動にラックギアと扇形歯車と穿孔刃駆動歯車（又は穿孔刃駆動片）を使用する２穴パンチ具に関する。 The present invention relates to a two-hole punching tool that uses a rack gear, a sector gear, and a drilling blade driving gear (or a drilling blade driving piece) for driving a drilling blade.
ラックギア、ピニオンギア及びピニオンギアと同軸の小歯車を使用するパンチ具が考案されている。（例えば、特許文献１参照。） Punch tools using a rack gear, a pinion gear, and a pinion gear coaxial with the pinion gear have been devised. (For example, refer to Patent Document 1.)
このパンチ具は、複数の穿孔刃が付いている１枚のプレートを２つの歯車で駆動する方式であるために、このプレートを正確に鉛直方向に駆動する必要があるが、歯車間の遊びのために２つの歯車を均等に駆動することは困難である。不均等に力が加えられたプレートを鉛直方向に均等に駆動するためには余分な力が必要であり、その分だけ大きな力を要することになる。 Since this punch tool is a system in which a single plate having a plurality of drilling blades is driven by two gears, it is necessary to drive this plate accurately in the vertical direction. Therefore, it is difficult to drive the two gears equally. In order to evenly drive the plate to which the force is applied evenly in the vertical direction, an extra force is required and a correspondingly large force is required.
本発明は、上記の問題を解決することを課題とする。 An object of the present invention is to solve the above problems.
上記の課題を解決するために、本発明（請求項１）の２穴パンチ具は、基台に固定されたケースの上に出ているハンドルを押し下げることにより、ハンドルに固定されたラックギアで、ケースに回転自在に軸支されラックギアの両側に対向して配置された２つの扇形歯車を回転させ、それぞれの扇形歯車に固着され扇形歯車と同軸である小歯車で、他方の回転軸に回転自在に軸支され、２つの穿孔刃駆動歯車が互いに抵触しないような形状及び配置である２つの穿孔刃駆動歯車を回転させ、穿孔刃駆動歯車で穿孔刃を駆動して書類を穿孔する、構成とした。 In order to solve the above-mentioned problem, the two-hole punch tool of the present invention (Claim 1) is a rack gear fixed to the handle by pushing down the handle coming out on the case fixed to the base, Two fan gears that are pivotally supported by the case and arranged opposite to both sides of the rack gear are rotated, and a small gear that is fixed to each fan gear and coaxial with the fan gear is rotatable on the other rotating shaft. And rotating the two drilling blade drive gears that are supported by the shaft and shaped and arranged so that the two drilling blade drive gears do not interfere with each other, and the punching blade is driven by the drilling blade drive gear to punch the document. did.
本発明（請求項２）の２穴パンチ具は、基台に固定されたケースの上に出ているハンドルを押し下げることにより、ハンドルに固定されたラックギアで、ケースに回転自在に軸支されラックギアの両側に対向して配置された２つの扇形歯車を回転させ、それぞれの扇形歯車に固着されたピンで、他方の回転軸に回転自在に軸支され、２つの穿孔刃駆動片が互いに抵触しないような形状及び配置である２つの穿孔刃駆動片を駆動し、穿孔刃駆動片で穿孔刃を駆動して書類を穿孔する、構成とした。 The two-hole punching tool of the present invention (Claim 2) is a rack gear that is pivotally supported on the case by a rack gear that is fixed to the handle by pushing down the handle that protrudes on the case that is fixed to the base. Two fan gears arranged opposite to both sides of the fan are rotated, and pins fixed to the respective fan gears are rotatably supported on the other rotary shaft, so that the two drilling blade drive pieces do not conflict with each other. Two perforation blade driving pieces having such shapes and arrangements are driven, and the perforation blade is driven by the perforation blade driving pieces to perforate the document.
本発明の２穴パンチ具は、２つの穿孔刃を個別に駆動するため、２つの穿孔刃が正確に均等に駆動される必要はなく、製造及び組み立てが容易である。 Since the two-hole punch tool of the present invention drives the two drilling blades individually, the two drilling blades do not need to be driven accurately and equally, and are easy to manufacture and assemble.
扇形歯車で直接穿孔刃を駆動することも可能であるが、これだと、２つの穿孔刃の間隔が固定されていることから、設計の自由度が極端に狭くなる。これに対し、本発明の穿孔刃駆動歯車（又は穿孔刃駆動片）を介在させることにより、設計の自由度が増し、大きい扇形歯車を採用すれば大きな穿孔力を得ることもできる。 Although it is possible to directly drive the drilling blade with a sector gear, since the interval between the two drilling blades is fixed, the degree of freedom in design becomes extremely narrow. On the other hand, by providing the drilling blade drive gear (or drilling blade drive piece) of the present invention, the degree of freedom of design is increased, and if a large sector gear is employed, a large drilling force can be obtained.
以下、本発明の実施の形態を図１〜図７に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.
本発明（請求項１）の２穴パンチ具にあっては、ハンドル４を下方に押し下げると、ラックギア５が下方に押し下げられ２つの扇形歯車７が回転する。これに伴い、扇形歯車７にそれぞれ固定されている小歯車８も回転し、穿孔刃駆動歯車Ａ１０及び穿孔刃駆動歯車Ｂ１１が下方に回転させられ、穿孔刃９が下方に押し下げられて書類を穿孔する。 In the two-hole punch of the present invention (Claim 1), when the handle 4 is pushed down, the rack gear 5 is pushed down and the two sector gears 7 rotate. Along with this, the small gears 8 fixed to the sector gears 7 are also rotated, the punching blade driving gear A10 and the punching blade driving gear B11 are rotated downward, and the punching blade 9 is pushed downward to punch the document. To do.
穿孔刃駆動歯車Ａ１０及び穿孔刃駆動歯車Ｂ１１の回転軸は扇形歯車７の回転軸６を利用するが、穿孔刃駆動歯車Ａ１０及び穿孔刃駆動歯車Ｂ１１が抵触しないよう、穿孔刃駆動歯車Ｂ１１を穿孔刃駆動歯車Ａ１０の上方を迂回させる。 The rotating shafts of the punching blade driving gear A10 and the punching blade driving gear B11 use the rotating shaft 6 of the sector gear 7, but the punching blade driving gear B11 is punched so that the punching blade driving gear A10 and the punching blade driving gear B11 do not conflict. The upper part of the blade drive gear A10 is bypassed.
本発明（請求項２）の２穴パンチ具にあっては、ハンドル４を下方に押し下げると、ラックギア５が下方に押し下げられ２つの扇形歯車７が回転する。これに伴い、扇形歯車７にそれぞれ固定されている穿孔刃駆動片駆動ピン１５が下方に移動し、穿孔刃駆動片Ａ１６及び穿孔刃駆動片Ｂ１７が下方に押し下げられ、穿孔刃９が下方に押し下げられて書類を穿孔する。 In the two-hole punch tool of the present invention (Claim 2), when the handle 4 is pushed down, the rack gear 5 is pushed down and the two sector gears 7 rotate. Along with this, the drilling blade drive piece drive pin 15 fixed to the sector gear 7 moves downward, the drilling blade drive piece A16 and the drilling blade drive piece B17 are pushed down, and the drilling blade 9 is pushed down. And punching documents.
穿孔刃駆動片Ａ１６及び穿孔刃駆動片Ｂ１７の回転軸は扇形歯車７の回転軸６を利用するが、穿孔刃駆動片Ａ１６及び穿孔刃駆動片Ｂ１７が抵触しないよう、穿孔刃駆動片Ｂ１７を穿孔刃駆動片Ａ１６の上方を迂回させる。 The rotary shaft of the sector gear 7 uses the rotary shaft 6 of the sector gear 7 as the rotation shaft of the drill blade driving piece A16 and the drill blade driving piece B17, but the drill blade driving piece B17 is drilled so that the drill blade driving piece A16 and the drill blade driving piece B17 do not conflict. The upper portion of the blade driving piece A16 is bypassed.
