Abstract

PROBLEM TO BE SOLVED: To provide a two-hole punch tool, short in the depth of a punch tool base, and also having large punching capability, in the present invention.SOLUTION: The two-hole punch tool is constituted so that a small gear arranged coaxially is fixed by pushing down a handle for fixing a rack gear downward, and two large gears journaled by a case are rotated, and the small gear respectively fixed to the two large gears is rotated thereby, and is thereby arranged so as to be sandwiched by the two small gears, and a rack gear is formed on its both ends, and a punching blade plate is moved downward, and thereby, a document is punched by two punching blades fixed to the punching blade plate.

Description

この発明は、穿孔刃の駆動にラックギヤと歯車を使用する小型の２穴パンチ具に関する。   The present invention relates to a small two-hole punch using a rack gear and a gear for driving a drilling blade.

パンチ具基台の奥行きが短くて、しかも、大きな穿孔能力を持つ２穴パンチ具を提供することを課題として、外ケースを押し下げることにより外ケースに連結されたラックギヤで軸を同じくする大小のピニオンギヤのうち大きい方を回転させ、小さいほうのピニオンギヤで穿孔刃が取り付けられたラックギヤを下方に押し下げて書類を穿孔する２穴パンチ具が考案されている。（例えば、特許文献１参照。）   The object is to provide a two-hole punching tool with a short punching tool base and a large drilling capability, and a large and small pinion gear with the same axis as a rack gear connected to the outer case by pushing down the outer case. A two-hole punching tool has been devised in which the larger one of them is rotated and the rack gear, to which the punching blade is attached, is pushed downward by the smaller pinion gear to punch the document. (For example, refer to Patent Document 1.)

しかし、この２穴パンチ具は、２つの穿孔刃を個別に駆動するために、大小の歯車が一体となっているものを４個使用しており、そのうち２つは、２つの穿孔刃の間に配置されている。
このため、大きい方の歯車の径を大きくすることができず、大小の歯車のギヤ比を大きくすることができない。 However, this two-hole punching tool uses four pieces of large and small gears integrated to drive the two drilling blades individually, two of which are between the two drilling blades. Is arranged.
For this reason, the diameter of the larger gear cannot be increased, and the gear ratio of the larger and smaller gears cannot be increased.

本発明は、パンチ具基台の奥行きが短くて、しかも、大きな穿孔能力を持つ２穴パンチ具を提供することを課題とする。   An object of the present invention is to provide a two-hole punch tool having a short punch tool base and a large punching ability.

上記の課題を解決するために、本発明の２穴パンチ具は、ラックギヤが固定されたハンドルを下方に押し下げることによって、軸を同じくする小歯車が固定され、ケースで軸支された、２つの大歯車を回転させ、これにより、２つの大歯車にそれぞれ固定された小歯車を回転させ、これにより、２つの小歯車によって挟み込まれるように配置され、その両端にラックギヤが形成された、穿孔刃プレートを下方に移動させ、これにより、穿孔刃プレートに固定された２つの穿孔刃で書類を穿孔する、構成とした。   In order to solve the above-mentioned problem, the two-hole punching tool of the present invention has two small gears having the same shaft fixed and supported by a case by pushing down a handle to which a rack gear is fixed. A drilling blade in which a large gear is rotated, thereby rotating a small gear fixed to each of the two large gears, thereby being arranged to be sandwiched between the two small gears, and rack gears are formed at both ends thereof. The plate was moved downward, whereby the document was punched with two punching blades fixed to the punching blade plate.

本発明の２穴パンチ具は、２つの穿孔刃が固定された穿孔刃プレートを両端から小歯車で駆動するが、２つの小歯車の回転軸の間の距離が２つの穿孔刃の間の距離よりも大きくなり、小歯車の回転軸と大歯車の回転軸は同じであるため、２つの大歯車の回転軸の間の距離も大きくなり、大歯車の半径を大きくすることができる。   The two-hole punching tool of the present invention drives a drilling blade plate to which two drilling blades are fixed from both ends with a small gear, and the distance between the rotation shafts of the two small gears is the distance between the two drilling blades. Since the rotation shaft of the small gear and the rotation shaft of the large gear are the same, the distance between the rotation shafts of the two large gears is also increased, and the radius of the large gear can be increased.

また、ケースの幅を広げることにより、穿孔刃プレートの幅はさらに広げることが可能であり、これによっても大歯車の半径を大きくすることができる。   Further, by expanding the width of the case, the width of the drilling blade plate can be further increased, and the radius of the large gear can also be increased by this.

大歯車の半径を大きくすることができれば、小歯車とのギヤ比を大きくすることができ、小さい力で大きい穿孔力を得ることができる。   If the radius of the large gear can be increased, the gear ratio with the small gear can be increased, and a large drilling force can be obtained with a small force.

以下、本発明の実施の形態を図１〜図３に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS.

ハンドル４を下方に押し下げると、ラックギヤ５が下方に押し下げられ２つの大歯車７が回転する。これに伴い、大歯車７に固定されている小歯車８も回転し、穿孔刃プレート９を下方に押し下げる。これにより、穿孔刃プレート９に固定された２つの穿孔刃１０が書類を穿孔する。   When the handle 4 is pushed down, the rack gear 5 is pushed down and the two large gears 7 rotate. Along with this, the small gear 8 fixed to the large gear 7 also rotates and pushes the drilling blade plate 9 downward. As a result, the two punching blades 10 fixed to the punching blade plate 9 punch the document.

ラックギヤ５を真下に押し下げるために、ラックギヤ５の刃が形成されていない面に突起を設け、ケース２にラックギヤガイド１４を設ける。ただし、ラックギヤ５をガイドする方法はこれに限定するものではなく、他の方法も可能である。   In order to push down the rack gear 5 directly below, a protrusion is provided on the surface of the rack gear 5 on which no blade is formed, and a rack gear guide 14 is provided on the case 2. However, the method of guiding the rack gear 5 is not limited to this, and other methods are possible.

穿孔刃プレート９の上下の動きをガイドするために、穿孔刃プレートガイド１２を設けるが、他の方法も可能である。   In order to guide the vertical movement of the drilling blade plate 9, a drilling blade plate guide 12 is provided, but other methods are possible.

本発明の２穴パンチ具を使用していない状態では、穿孔刃１０を最上部に維持しておくためにバネ１３を設けるが、穿孔刃プレート９をバネ等により最上部に維持する方法も可能である。   In a state where the two-hole punching tool of the present invention is not used, a spring 13 is provided to keep the drilling blade 10 at the uppermost position, but a method of maintaining the drilling blade plate 9 at the uppermost position by a spring or the like is also possible. It is.
