Description

本発明はボルトに挿入した後、回転させることによりボルトのねじ部と螺合するナットセグメントを備えるナットに関する。   The present invention relates to a nut provided with a nut segment that is screwed with a threaded portion of a bolt by being rotated after being inserted into the bolt.

従来のこの種のナットは外壁が多角形状に形成され、内壁に順次小径寸法となる傾斜孔を有するナット本体と、このナット本体の大径側の端部に形成されたボルト挿入孔を有するストッパー片と、前記ナット本体の内壁面の軸心方向に形成された、少なくとも３個以上のガイド片と、これらのガイド片間に軸心方向にスライド移動可能に取付けられた内壁面にボルトと螺合されるねじ山が形成された少なくとも３個以上のナットセグメントと、前記ナット本体の小径側の端部に固定された、前記少なくとも３個以上のナットセグメントの抜け脱を防止するとともに、該ナット本体の外周部よりも外方に突出するフランジ状の取付片と、前記少なくとも３個以上のナットセグメントを常時前記ナット本体の小径側に付勢するように、該ナット本体内に収納された付勢スプリングとで構成されている。   A conventional nut of this type has a nut body having an outer wall formed in a polygonal shape, and an inner wall having an inclined hole that gradually becomes smaller in diameter, and a stopper having a bolt insertion hole formed at an end portion on the large diameter side of the nut body. And at least three guide pieces formed in the axial direction of the inner wall surface of the nut body, and bolts and screws on the inner wall surface slidably mounted between these guide pieces in the axial direction. And at least three nut segments formed with a thread to be joined, and the at least three nut segments fixed to the end portion on the small diameter side of the nut body are prevented from coming off and the nuts A flange-shaped mounting piece projecting outward from the outer peripheral portion of the main body and the nut book so as to constantly urge the at least three nut segments toward the small diameter side of the nut main body. It is composed of a biasing spring housed within.

このように構成されたナットはボルトに挿入して、締付け方向に回転させることにより、ボルトのねじ部に３個のナットセグメントが螺合するが、常にねじ山１個分のクリアーがあったり、なかったりするという欠点があった。
特開平１１−７２１１０ By inserting the nut configured in this way into the bolt and rotating it in the tightening direction, the three nut segments are screwed into the threaded portion of the bolt, but there is always clearness for one thread, There was a drawback of not.
JP-A-11-72110

本発明は以上のような従来の欠点に鑑み、ボルトに挿入して、締付け方向に回転させることにより、ボルトのねじ部に少なくとも３個以上のナットセグメントが螺合するとともに、ナットセグメントを収納したナット本体を常時螺合方向に付勢してナットセグメントの遊びをなくし、確実な螺合状態を保つことができるナットを提供することを目的としている。   In view of the above-described conventional drawbacks, the present invention is inserted into a bolt and rotated in the tightening direction, so that at least three nut segments are screwed into the screw portion of the bolt and the nut segment is accommodated. It is an object of the present invention to provide a nut capable of constantly urging the nut body in the screwing direction to eliminate the play of the nut segment and maintaining a reliable screwed state.

本発明の前記ならびにそのほかの目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。 The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

上記目的を達成するために、本発明はボルトの挿入後、螺合方向へ回転させると挿入されたボルトのねじ部と螺合する少なくとも３個以上のナットセグメントおよび、該ナットセグメントを付勢するナットセグメント付勢スプリングが収納されたナット本体と、このナット本体の上部を除く外周部に上端部が該ナット本体と一体になって回転するように取付けられたスプリングケースと、このスプリングケースの下部に回転可能に取付けられた座金と、前記スプリングケース内に収納された一端部が該スプリングケースあるいはナット本体に、他端部が前記座金にナット本体をボルトに螺合させると螺合方向に常時付勢できるように取付けられたナット本体付勢スプリングとでナットを構成している。   To achieve the above object, according to the present invention, when a bolt is inserted and then rotated in a screwing direction, at least three nut segments that are screwed with a screw portion of the inserted bolt and the nut segment are urged. A nut body in which a nut segment urging spring is housed, a spring case attached to an outer peripheral portion excluding the upper part of the nut body so that an upper end portion is rotated integrally with the nut body, and a lower part of the spring case A washer that is rotatably attached to the spring case, one end housed in the spring case is screwed into the spring case or the nut body, and the other end is screwed into the washer when the nut body is screwed into the bolt. The nut is composed of a nut body biasing spring attached so as to be biased.

以上の説明から明らかなように、本発明にあっては次に列挙する効果が得られる。   As is clear from the above description, the present invention has the following effects.

[発明を実施するための異なる形態] As shown in FIG. 11, the nut 1 having the above-described configuration is inserted into a bolt 2 attached to a portion where the timbers 29 and 29 are fixed, and is brought into contact with the timber 29. At this time, the nut segments 4, 4, 4 slide to the large diameter side of the inclined hole 12 against the urging force of the nut segment urging spring 5, thereby allowing the bolt 2 to enter.
Next, the nut case 13 of the nut body 6 is rotated in the tightening direction by using a spanner or the like, so that the thread portions 17 and 17 of the threaded portion 3 of the bolt 2 and the nut segments 4, 4, 4, as shown in FIG. , 17 are screwed together to fasten and fix the timbers 29, 29, and a biasing force is applied to the nut body biasing spring 9.
For this reason, the urging force of the nut body urging spring 9 urges the nut body 6 to always rotate in the tightening direction, eliminates play of the nut segments 4, 4, 4, and ensures a secure screwed state. Can keep.
