Description

本発明は、タガネ、鑿、杭等の、手でもってハンマーで打撃し加工を行う打撃加工具及び把持具に関するものである。 TECHNICAL FIELD The present invention relates to a hammering tool and a gripping tool , such as chisels, chisels, and piles, which are manually struck with a hammer.

図6は、このような用途に向けた従来の把持具を示す図である。特許文献1に見ることができる。ハンマー等で打撃される加工具1を内包して垂直方向にガイドするための支え体2があり、加工具1の上部には、ピン5により押え座金4が固定され、押え座金4と加工具1の下部との間には、巻きバネ3が存在する。支え体2の側面には、握りハンドル6が付いている。この機能を述べると、握りハンドル6を手で握り、ハンマー等で加工具1の頭を打撃するので、加工具1を直接手で握ったときより、安全に加工できる。そして、巻きバネ3により打撃が存在するので、握りハンドル6をにぎった手には衝撃が伝わりにくいと述べている。然しながら、この構造では、検討の結果、次の欠点があることが分かる。
先ず、これを組み立てる場合を考えてみると、押え座金4の加工具1への固定は、どのようにして行うのかが疑問である。支え体内では、押え座金4を付けにくそうに見える。
支え体2に加工具1を挿入する前に押え座金4を付けると、支え体2には下側から挿入するしかない。挿入後に巻きバネ3を嵌め、ネジ蓋7をねじ込み締める。このような操作が必要なので、サイズ等の違った加工具1に対処するには、保持具全体を付け替えるのは、面倒になるため、加工具1ごとに保持具を容易することになる不便があり、組み立てが容易でない分使いにくい。そして、巻きバネ3があるので衝撃が伝わりにくいとはいえ、
加工具1の移動の衝撃は、押え座金4と巻きバネ3を介して、支え体2の下部のネジ蓋7を押すので、それに固定された握りハンドル6、従って手に動きが伝わる欠点がある。押え座金4、巻きバネ3、ネジ蓋7という構成が、目的とは逆の悪さをしてしまい余計な構成となっている。更に、構成が複雑になるので製作価格が上がる欠点がある。
FIG. 6 shows a conventional gripper intended for such use. It can be seen in US Pat. There is a support 2 for enclosing and vertically guiding a processing tool 1 to be struck by a hammer or the like. A coil spring 3 is present between the lower part of 1 and the lower part. A grip handle 6 is attached to the side of the support 2. - 特許庁As for this function, since the grip handle 6 is gripped by hand and the head of the processing tool 1 is hit with a hammer or the like, processing can be performed more safely than when the processing tool 1 is directly gripped by hand. Further, since there is an impact due to the winding spring 3, it is described that the impact is hardly transmitted to the hand holding the grip handle 6. However, as a result of examination, this structure has the following drawbacks.
First, considering the case of assembling this, it is questionable how to fix the presser washer 4 to the processing tool 1 . It seems difficult to attach the presser washer 4 inside the support body.
If the presser washer 4 is attached before inserting the processing tool 1 into the support 2, it must be inserted into the support 2 from below. After the insertion, the coil spring 3 is fitted, and the screw lid 7 is screwed and tightened. Since such an operation is necessary, it is troublesome to replace the entire holder in order to cope with the processing tools 1 having different sizes, etc., so it is inconvenient to replace the holder for each processing tool 1. Yes, it is difficult to use because it is not easy to assemble. And although the shock is hard to be transmitted because there is a winding spring 3,
The impact of movement of the processing tool 1 pushes the screw lid 7 at the bottom of the support 2 via the presser washer 4 and the coil spring 3, so there is a drawback that the movement is transmitted to the grip handle 6 fixed thereto and thus to the hand. . The configuration of the presser washer 4, the coil spring 3, and the screw lid 7 serves the opposite purpose and is an unnecessary configuration. Furthermore, the structure becomes complicated, so there is a drawback that the production cost rises.
