【００１８】 ２１はパンチでＥリング２２により保持されている。パンチ２１はベース１の パンチ孔２３に垂直に設けられている。２４は前記フレームの側面の中央に設け た角孔。２５はレバーで後方寄りは、左右に分割された側板２６．２６．２６． ２６が形成されている。２７は支軸で、レバー２５の側板２６．２６．２６．２ ６とパンチ押し具１９の側板２０．２０との間に挿通し架設した支軸で、この支 軸２７の片側の頭部２８側には、基端を止着した略倒Ｌ形のストッパー２９を設 ける。このストッパー２９の曲折部３０は内側方に曲折しており、先端には係止 部３１が設けられ、レバー２５の一側板２６に設けられた角孔３２に臨設し、常 時この角孔３２内に収容している。３３は前記ストッパー２９とレバー２５の側 板２６との間に介装した伸張弾機で、常に外方に伸張しようとしている。３４． ３４は前記レバー２５と左右フレーム１５．１５の中央上端に架設した支点軸で 、この支点軸３４．３４にはレバー２５を持ち上げる支点発条３５．３５がその 一端をレバー２５の内側に当接し、他端部を左右フレーム１５．１５の突起３６ ．３６に当接している。A punch 21 is held by an E-ring 22. The punch 21 is provided perpendicularly to the punch hole 23 of the base 1. 24 is a square hole provided in the center of the side surface of the frame. 25 is a lever, and the rear side is a side plate 26.26.26. 26 is formed. Reference numeral 27 is a support shaft, which is a support shaft that is inserted and installed between the side plates 26.26.26.26 of the lever 25 and the side plates 20.20 of the punch pressing tool 19, and the head 28 on one side of the support shaft 27. On the side, a substantially inverted L-shaped stopper 29 having its base end fixed is provided. The bent portion 30 of the stopper 29 is bent inward, and a locking portion 31 is provided at the tip of the stopper 29. The stopper 29 is provided in a square hole 32 provided in one side plate 26 of the lever 25, and the square hole 32 is always provided. It is housed inside. Numeral 33 is an extension bullet which is interposed between the stopper 29 and the side plate 26 of the lever 25, and is always trying to extend outward. 34. 34 is a fulcrum shaft which is installed at the center upper ends of the lever 25 and the left and right frames 15.15. A fulcrum spring 35.35 for lifting the lever 25 abuts one end of the fulcrum shaft 35.35 on the inside of the lever 25. The other end is provided with protrusions 36. It is in contact with 36.
【００１９】 こうしてレバー２５を押下て、パンチ押し具１９の下面がパンチ支持部１８の 上面に当たったとき、ストッパー２９の下端部を指先で押し当てると、伸張弾機 ３３は収縮して、ストッパー２９の係止部３１が、前記フレーム１５の角孔２４ より内方向に移動したらレバーを離す。すると支点発条３５が伸張弾機３３より 反発力を強くしてあるため、ストッパー２９の係止部３１がフレーム１５の角孔 ２４の内側縁部に係止するとともに、曲折部３０も、角孔２４の上端部に強く係 合するようになり、ストッパー２９の下端部より指先を離す。これによりレバー ２５は固定され開かなくなる。（図９．図１０．図１１参照）When the lower surface of the punch pusher 19 hits the upper surface of the punch support section 18 by pressing the lever 25 in this way, the lower end of the stopper 29 is pressed with a fingertip, so that the extension bullet machine 33 contracts and the stopper is stopped. When the locking portion 31 of 29 moves inward from the square hole 24 of the frame 15, the lever is released. Then, since the fulcrum spring 35 makes the repulsive force stronger than the extension bullet 33, the engaging portion 31 of the stopper 29 engages with the inner edge of the square hole 24 of the frame 15, and the bent portion 30 also has a square hole. The upper end of the stopper 24 is tightly engaged, and the fingertip is separated from the lower end of the stopper 29. As a result, the lever 25 is fixed and cannot be opened. (See FIG. 9, FIG. 10, and FIG. 11)
【００２０】 レバー２５を開く時は、レバー２５を軽く押下すると、レバー２５の下動によ りレバー２５の側板２６に設けた角孔３２に挿入されていたストッパー２９も下 動しストッパー２９が係止部３１の突起量分移動すると角孔２４の内側縁部より 解除されると同時に、ストッパー２９の曲折部３０も角孔２４の上端部より離れ 、伸張弾機３３によって、ストッパー２９の係止部３１が外方に移動し、レバー ２５を離すと、支点発条３５よりレバー２５が開放される。（図７．図８参照）When the lever 25 is opened, when the lever 25 is lightly pressed, the lower movement of the lever 25 also lowers the stopper 29 inserted in the square hole 32 provided in the side plate 26 of the lever 25, and the stopper 29 is opened. When the locking portion 31 is moved by the protrusion amount, it is released from the inner edge of the square hole 24, and at the same time, the bent portion 30 of the stopper 29 is also separated from the upper end portion of the square hole 24, and the extension ammunition 33 engages the stopper 29. When the stopper 31 moves outward and releases the lever 25, the lever 25 is released from the fulcrum spring 35. (See FIG. 7 and FIG. 8)
【００２１】[0021]
以上説明したように、レバーの閉口操作においては、レバーを押下て、ストッ パーの下端部を軽く押すだけでストッパーの係止部がフレームの角孔の内側縁部 に係止するとともに、曲折部がフレーム角孔の上端部に押圧され、レバーが閉口 状態となる。又レバーの開口操作においては、レバーを少し押すとフレームの角 孔の内側縁部に係止していたストッパーの係止部が移動し、ストッパーが係止部 の突起量分移動すると角孔の内側縁部より解除される。同時にストッパーの曲折 部も角孔の上端部より離れ、伸張弾機により、係止部が外方に移動しレバーを離 すと支点発条により、レバーが開口状態となる。このため簡単な操作によりレバ ーの格納固定を確実かつ迅速に行なうことが出来、又パンチ全体の外観を損なう 事無く製作が可能となり、その実用的効果は大きいものである。 As explained above, when closing the lever, simply press the lever and lightly press the lower end of the stopper to engage the stopper locking part with the inner edge of the square hole of the frame, and to bend the bent part. Is pressed against the upper end of the frame square hole, and the lever is closed. In the lever opening operation, when the lever is pushed a little, the stopper of the stopper, which was locked on the inner edge of the square hole of the frame, moves, and when the stopper moves by the protrusion amount of the stopper, the square hole It is released from the inner edge. At the same time, the bent part of the stopper also separates from the upper end of the square hole, and when the stretchable ammunition moves the locking part outwards and releases the lever, the fulcrum spring opens the lever. For this reason, the lever can be securely and quickly fixed and stored by a simple operation, and the punch can be manufactured without damaging the appearance of the entire punch, which has a great practical effect.
【００２２】 板ばねの起し部はベース内面に、板ばねの中央は、ベース一対の突部の内面に それぞれ当接し、上動を阻し、板ばねの両端の係止部がそれぞれ、ベース段部に 係止し、左右の移動を阻止するため、輸送時による外れや紛失を防止できる。更 にベース両側面の角孔と板ばねの上端に角孔を設けたゲージを通し、ゲージを引 き過ぎた時板ばねの曲げ高さの低い側に設けた起し部が角孔に係合し、ゲージの 抜けを防止できるため、いちいち組付けをする煩わしさが無くなる。The raised portion of the leaf spring is in contact with the inner surface of the base, and the center of the leaf spring is in contact with the inner surfaces of the pair of protrusions of the base to prevent upward movement. Since it is locked on the step and prevents left and right movement, it can be prevented from coming off or being lost during transportation. In addition, insert a gauge with square holes on both sides of the base and square holes at the upper end of the leaf spring, and when the gauge is pulled too much, the raised portion provided on the side with a low bending height of the leaf spring engages the square hole. In this case, it is possible to prevent the gauge from coming off, eliminating the hassle of assembling each time.
