The present invention relates to a fastening structure used for fastening bolts, rods, and pipes formed by coaxially crossing right-handed and left-handed threads, and for fastening joints.
従来、ボルトとナットに代表されるこの類の締結構造は、各種車両や航空機産業及び工作機器、各種建造物等において、部材等の締結に広く使用されている。しかし長年これらの締結構造は締結部分が緩む問題があった。
一般的にボルト、棒材、パイプ材は締結部分の軸上に一本の右ネジが成形されており、それに対して右ネジナットで締結するが、この締結部分が振動などの原因で緩む問題があった。締結構造の一つに、上記の一般的な締結構造とは異なり、同軸上に右ネジと左ネジを交差させて形成されたボルトを利用し、右ネジナットと左ネジナットどうしを固定する事によりボルトと二つのナットを締結する方法も古くからある。特許文献１や特許文献２がそれらである。しかしながらこれらの文献にある技術は右回ネジナットと左ネジナットどうしを締結する部分に摩擦を利用するなど、ネジの緩み防止上信頼性に欠ける。
特許文献３も上記の同軸上に右ネジと左ネジを交差させて形成されたボルトを使用し、右回ネジナットと左ネジナットどうしを固定する事による締結構造としているが、その構造が複雑すぎるとか、締結の解除が簡単にできないのどの問題がある。 Conventionally, this type of fastening structure represented by bolts and nuts has been widely used for fastening members in various vehicles, the aircraft industry, machine tools, various buildings, and the like. However, for many years, these fastening structures have had the problem of loosening of fastening parts.
In general, bolts, bars, and pipes have a single right-hand thread formed on the shaft of the fastening part, and are fastened with a right-hand thread nut, but there is a problem that this fastening part loosens due to vibration etc. there were. In one of the fastening structures, unlike the above general fastening structure, a bolt formed by intersecting a right-handed thread and a left-handed thread on the same axis is used, and the right-handed nut and the left-handed nut are fixed to each other. There is also an old method of fastening two nuts.Patent document 1 and patent document 2 are those. However, the techniques in these documents lack reliability in terms of preventing loosening of the screw, such as using friction in the portion where the right-hand screw nut and the left-hand screw nut are fastened together.
Patent document 3 also uses a bolt formed by intersecting a right-handed screw and a left-handed screw on the same axis, and has a fastening structure by fixing the right-handed screw nut and the left-handed screw nut, but the structure is too complicated. , there is a problem that the fastening cannot be released easily.
一般的にボルト、棒材、パイプ材は締結部分の軸上に一本の右ネジが成形されており、それに対して右ネジナットで締結するが、この締結部分が振動などの原因で緩む問題があった。締結構造の一つに、上記の一般的な締結構造とは異なり、同軸上に右ネジと左ネジを交差させて形成されたボルトを利用し、右ネジナットと左ネジナットどうしを固定する事によりボルトと二つのナットを締結する方法も古くからある。特許文献１や特許文献２がそれらである。しかしながらこれらの文献にある技術は右回ネジナットと左ネジナットどうしを締結する部分に摩擦を利用するなど、ネジの緩み防止上信頼性に欠ける。

一般的な同軸上に一本の右ネジが形成されたボルトを使用する場合、振動などの外力が継続的にかかると、ボルトのねじ山とナットのねじ山との間に極僅かであったとしてもずれが生じる。この僅かなずれが継続的に進行し、ずれの部分が大きくなり締結部分が緩む場合が多い。 本発明においては、図４に示す様に、同軸上に右ネジと左ネジを交差させて形成されたボルト（１）上での締結構造であるため、一度右ネジナット（２）と左ネジナット（３）がかみ合いロックされると、振動などの外力により僅かなずれが生じたとしても、右ネジナット（２）と左ネジナット（３）が互いにずれを元に戻す方向に回転しようとし、ずれの更なる進行はない。 波状に形成された締め付け面を持つナットや座金は既存技術として数多く存在するが、本発明の右ネジナット（２）と左ネジナット（３）は従来の同軸上に一本のネジ山が形成されたボルト上で機能するものとは上記の様に構造原理が大きく異なる。 また、構造が複雑過ぎず、特殊な工具を必要とせず簡単に締結作業を行うことができ、締結の解除も容易である。
図５及び図６は同軸上に右ネジと左ネジを交差させて形成された棒材（５）を締結する際に用いる継ぎ手の締結構造である。 この結合構造においても一度継ぎ手部材（６）と二つのナット（２）がかみ合いロックされると緩みが生じる事はない。

However, deviation occurs. In many cases, this slight deviation progresses continuously, the deviation becomes large, and the fastening portion loosens. In the present invention, as shown in FIG. 4, since it is a fastening structure on the bolt (1) formed by coaxially crossing the right-handed screw and the left-handed screw, the right-handed screw nut (2) and the left-handed screw nut ( When 3) is meshed and locked, even if a slight deviation occurs due to an external force such as vibration, the right screw nut (2) and the left screw nut (3) will try to rotate in the direction to restore the deviation, and the deviation will be further corrected. No further progress. There are many nuts and washers with wavy tightening surfaces as existing technology, but the right-hand screw nut (2) and left-hand screw nut (3) of the present invention are conventionally formed with a single screw thread on the same axis. As mentioned above, the structural principle is very different from that which functions on bolts. In addition, the structure is not too complicated, the fastening work can be easily performed without requiring a special tool, and the fastening can be easily released.
