Abstract

PROBLEM TO BE SOLVED: To provide a screw that does not drop off from a screw driver whatever material quality may be used in the screw and additionally the screw can be easily fastened with one hand even if the working location is narrow to eliminate inconvenience that the screw of non-magnetic raw material cannot be held by a screw driver and the fastening work should be performed while holding the screw with one hand and additionally the screw is hardly held at the narrow part by a screw driver including tweezers.SOLUTION: A screw having an elliptical or polygonal hole at its head part to which a screw fastening tool is enabled to be held by a screw fastening tool and to perform a fastening work easily only with one hand without being dropped by making the hole having a tapered surface deeper as it becomes deeper continuously to a deep side of a vertical surface that is formed in the same size from the end surface of the fitting hole toward its depth direction and the screw fastening tool is held by the tapered surface.SELECTED DRAWING: Figure 1

Description

本発明は、楕円形又は多角形の嵌合穴を有するネジに関する。  The present invention relates to a screw having an elliptical or polygonal fitting hole.

従来より、ネジを締める際に、ネジ回しからネジが落ちないように先に磁石が付随している工具がある。  Conventionally, when tightening a screw, there is a tool accompanied by a magnet first so that the screw does not fall from the screwdriver.

また、ネジ回しの先にピンセットを取り付け、ネジの着脱時にネジが落ちないようにした工具がある。  In addition, there is a tool in which tweezers are attached to the tip of a screwdriver so that the screw does not fall when the screw is attached or detached.

発明が解決するための課題Problems to be Solved by the Invention

以上に述べた従来のネジ締め工具では、次のような問題点があった。
イ．ネジの材質が、非磁性であるステンレス、アルミ、樹脂、プラスチック、真鍮などの材質では磁石を用いた方法ではネジを保持することができないためどうしても片方の手で、ネジを保持しながら作業をする必要がある。
ロ．ピンセットを用いた工具の場合、使用する場所が狭間部では使いにくい。The conventional screw tightening tool described above has the following problems.
A. The material of the screw, stainless is non-magnetic, aluminum, resin, plastic, with absolutely one hand it is not possible in a material such as brass which holds the screw in a method using a magnet, to work while holding the screw There is a need.
B. In the case of a tool using tweezers, it is difficult to use in a narrow space.

本発明は、以上のような問題を解決するためになされたもので、ネジ側に工夫をすることによってネジの材質を問わず、しかも片手でネジを落とさず、狭間部でも容易にネジを締めることを可能にすることを目的とする。  The present invention has been made to solve the above problems, and by contriving the screw side, regardless of the material of the screw, the screw can be easily tightened even in a narrow space without dropping the screw with one hand. It aims to make it possible.

課題を解決するための手段Means for solving the problem

本発明は上記目的を達成するためのネジで、楕円形又は多角形の工具が嵌まり込む嵌合穴を有するネジであり、前記嵌合穴は端面から深さ方向に同寸法で形成されている垂直面と、垂直面の奥側に連続して深くなるに従って窄まるテーパー面を有している穴で形成され、このテーパー面でネジを挟持するものである。  The present invention is a screw for achieving the above object, and has a fitting hole into which an elliptical or polygonal tool is fitted, and the fitting hole is formed in the same direction in the depth direction from the end face. And a hole having a tapered surface that narrows as it becomes deeper continuously on the back side of the vertical surface, and a screw is sandwiched between the tapered surfaces.

発明の効果Effect of the invention

本発明の落下防止機能付きネジを使用することによって、次の様な効果がある。
イ．非磁性のネジでも、ネジが落下することなく容易に着脱の作業を容易に行うことができる。
ロ．手が届かない場所や隙間が狭い場所にもネジを容易に取り付けることができる。By using the screw with a fall prevention function of the present invention, the following effects are obtained.
A. Even non-magnetic screws can be easily attached and detached without the screws falling.
B. Screws can be easily attached to places that are out of reach or where the gap is narrow.

本発明の実施の形態について、図を用いて説明する。Embodiments of the present invention will be described with reference to the drawings.

図１は、本発明の実施形態におけるネジの全体構成である。
頭部に楕円形又は多角形の穴を有するネジの一例として六角形穴を持つキャップボルトで説明する。
ネジ１は、頭部に六角の嵌合穴２を有し、深さ方向に同寸法で形成されている垂直面４と、深くなるに従って窄まるテーパー面３で形成されている。FIG. 1 is an overall configuration of a screw according to an embodiment of the present invention.
A cap bolt having a hexagonal hole will be described as an example of a screw having an elliptical or polygonal hole in the head.
The screw 1 has a hexagonal fitting hole 2 in the head, a vertical surface 4 formed with the same dimension in the depth direction, and a tapered surface 3 that narrows as it gets deeper.

図２は、上記の実施形態のネジ１を用いて六角レンチ５で挟持している様子を示した図である。
テーパー面３は、六角レンチ５の頭部よりも狭くなっていることで、挟み込みの力を利用して六角レンチ５を挟持できるので落下を防ぐことができる。
すなわち、六角レンチ５は、ネジ１を挟持できるので、手が入りにくい狭所での作業や片手での作業が容易になる。FIG. 2 is a view showing a state in which the screw 1 of the above embodiment is used to hold it with a hexagon wrench 5.
Since the taper surface 3 is narrower than the head of the hexagon wrench 5, the hexagon wrench 5 can be clamped using the pinching force, so that the fall can be prevented.
That is, since the hexagon wrench 5 can hold the screw 1, the work in a narrow place where the hand is difficult to enter or the work with one hand becomes easy.

深さ方向に同寸法で形成されている垂直面４と、深くなるに従って窄まるテーパー面３の径の大きさを変えることであらゆるサイズのレンチに対応することが可能である。  It is possible to deal with wrench of any size by changing the size of the diameter of the vertical surface 4 formed with the same dimension in the depth direction and the tapered surface 3 that narrows as it gets deeper.

図３は、上記の実施形態のネジ１を嵌合穴２の端面側から見た図である。嵌合穴２の形状は、六角形状とは限らない。他の多角形状や楕円形状のネジでも同様のテーパー面を有することで、レンチを挟持することが可能である。  FIG. 3 is a view of the screw 1 of the above embodiment as viewed from the end face side of the fitting hole 2. The shape of the fitting hole 2 is not necessarily hexagonal. The wrench can be clamped by having a similar tapered surface with other polygonal or elliptical screws.

嵌合穴２のテーパー面３はネジ１と同じ材質でなくてもよい。
テーパー面３の周辺の材質は、ネジ１と異種の金属、樹脂、木、ガラス、ゴム、およびシリコンを用いてもよい。
テーパー面３と六角レンチ５との噛み合いをより強固にすることで、より挟持力を増す材質を選ぶことが可能である。The tapered surface 3 of the fitting hole 2 may not be the same material as the screw 1.
The material around the tapered surface 3 may be a metal different from that of the screw 1, resin, wood, glass, rubber, and silicon.
By further strengthening the meshing between the tapered surface 3 and the hexagon wrench 5, it is possible to select a material that further increases the clamping force.

この実施形態のネジの総称にはボルト又はナットが含まれる。  The generic name of the screw of this embodiment includes a bolt or a nut.
