(57) [Summary] [Objective] This invention provides a tool-use recess at the tip of bolts and screws, and tightens not only from the head like conventional bolts and screws, but also from the tips of bolts and screws. The present invention relates to a bolt / screw provided with a tool use concave portion at a tip end portion thereof so that loosening work can be performed. [Composition] A tool use recess (3) is provided on the tip (2) of the bolt / screw (1).
Description
【０００１】[0001]
この考案は、ボルト・ネジの先端部に工具使用凹部を設けたボルト・ネジに 関するものである。 The present invention relates to a bolt / screw in which a tool use recess is provided at the tip of the bolt / screw.
【０００２】[0002]
従来のボルト・ネジは、頭部より工具などを使用し締め付け、緩めを行って いた。 Conventional bolts and screws were tightened and loosened using a tool from the head.
【０００３】[0003]
これは次のような欠点があった。 （イ）ボルト・ネジの締め付け、緩めはボルト・ネジ頭部より行うためボルト ・ネジの先端部からは、この作業が行えなかった。 （ロ）ボルト・ネジが折れてしまうと、取り外しが困難で、特殊工具を使用し たり新たにボルト・ネジ用穴を加工しなければならない。 This had the following drawbacks. (A) Since the bolts and screws are tightened and loosened from the bolt and screw heads, this work could not be performed from the bolt and screw tips. (B) If the bolts and screws are broken, it is difficult to remove them, and special tools must be used or new holes for bolts and screws must be drilled.
【０００４】[0004]
いま、その構成を説明すると、 ボルト・ネジ（１）の先端部（２）に工具使用凹部（３）を設けたことを特 徴としたボルト・ネジ。 The structure of the bolt / screw will now be described. The bolt / screw (1) is provided with a tool use recess (3) at the tip (2).
【０００５】[0005]
次に本考案の作用を述べると、 工具使用凹部（３）に工具を使用することにより、ボルト・ネジ（１）の先 端部（２）側より締め付け、緩めが行える。 また、ボルト・ネジが折れた場合、ボルト・ネジ（１）の先端部（２）の工 具使用凹部（３）に工具を使用することにより折れ残った部分を抜くこともで きる。 Next, the operation of the present invention will be described. By using a tool in the tool use recess (3), the bolt / screw (1) can be tightened and loosened from the front end (2) side. Further, when the bolt / screw is broken, it is also possible to remove the unbroken portion by using a tool in the tool use recess (3) of the tip portion (2) of the bolt / screw (1).
【０００６】[0006]
以下、本考案の実施例について説明する。 ボルト・ネジ（１）の先端部（２）に工具使用凹部（３）を設けたボルト・ ネジであり、従来の頭部（４）からの作業と同様に工具使用凹部に工具を使用 しボルト・ネジ（１）を先端部（２）側より締め付け、緩めが行える。 なお、工具使用凹部（３）の形状を工具使用凸部（５）や工具使用凸部（５ ） 内に工具使用凹部を設けたり、各国のボルト・ネジ、工 具、その他各規格 に 準じたものとしても効果は、同じである。 Embodiments of the present invention will be described below. Bolts / screws (1) with tool use recesses (3) provided at the tip (2) of the bolt and screw, using the tool in the tool use recesses as in the conventional work from the head (4). -The screw (1) can be loosened by tightening it from the tip (2) side. In addition, the shape of the tool use concave part (3) was set according to the standards such as the tool use convex part (5) and the tool use concave part in the tool use convex part (5), and the bolts and screws, tools, and other standards of each country. The effect is the same as that of the thing.
【０００７】[0007]
本考案は上記した構造をなすものであるから、従来のボルト・ネジのように 頭部からだけでなく、ボルト・ネジ先端部からも締め付け、緩めの作業が容易 に行える。 Since the present invention has the above-described structure, it can be easily tightened and loosened not only from the head like conventional bolts and screws, but also from the tip of the bolts and screws.
