よる立体トラスの組立方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ratchet wrench for connecting a single member constituting a space truss and a ball joint, and a method for assembling a space truss using the ratchet wrench.

連結されている。[Conventional technology and problems to be solved] Generally, when constructing a three-dimensional truss by three-dimensionally connecting many single members such as steel pipes, ball joints are often used to connect the single members. However, the single material and the ball joint are connected by incorporating a connector in advance into a nose cone protruding from the end of the single material, and screwing this connector into a screw hole on the surface of the ball joint.
当山願人はこのような構造のトラスの継手構造を実願昭
６２−１０８６２８号に於いて既に出願している。Ganjin Toyama has already applied for a joint structure for a truss having such a structure in Utility Application No. 108628/1983.

るように螺合される。In addition, a ratchet wrench is used to tighten this connector, and the ratchet wrench is inserted into the through hole of the ball joint, and the threaded square rod tip of the ratchet wrench is inserted into the hexagonal hole at the tip of the connector, and the connector is tightened. It is screwed into the ball joint by being pulled deep into the screw hole using a ratchet wrench.

き抜けるように極めて短い六角棒ソケットを使用する必
要がある（第５図及び第６図参照）。In such cases, the original connector is located deep inside the nose cone, so it is necessary to use a wrench with a long hex socket that can reach it, and the connector is screwed deep into the screw hole of the ball joint. As the ball joint is fitted, it is necessary to gradually replace it with a shorter hexagonal socket, and finally use a very short hexagonal socket so that the wrench can be pulled out of the ball joint (see Figures 5 and 6).
この為、従来のラチェットレンチでは一箇所の単材と球
継手との連結に長さの異なる数種類の六角棒ソケットを
必要とするだけでなくこれを途中で何回か交換しながら
締付けを行う必要がある為、連結作業が極めて面倒であ
った。For this reason, conventional ratchet wrenches not only require several types of hexagonal bar sockets of different lengths to connect a single piece of material to a ball joint, but also need to be replaced several times during tightening. Therefore, the connection work was extremely troublesome.
また、球継手のサイズ及びコネクターの組み合わせによ

以下、この発明に係るラチェットレンチを図示する一実
施例に基づいて説明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a ratchet wrench according to the present invention will be described below.
ラチェットレンチ１はレンチ本体２とソケット３とねじ
性力角棒４とから構成されている。The ratchet wrench 1 is composed of a wrench body 2, a socket 3, and a threaded square rod 4.
レンチ本体２は略円筒形状に形成され、その基端部にハ
ンドル５が一体的に突設されている。The wrench body 2 is formed into a substantially cylindrical shape, and a handle 5 is integrally protruded from the base end thereof.
また、レンチ本体２の先端部にはレンチ本体２の内径よ
り一回り小さい径のねじ孔６が形成されている。Further, a screw hole 6 having a diameter one size smaller than the inner diameter of the wrench body 2 is formed at the tip of the wrench body 2.
ソケット３はレンチ本体２の内径より一回り小さい径の
略円筒形状に形成されていると共にレンチ本体２の中に
挿入され、且つその基端部にレンチ本体２との間にいわ
ゆるラチェット機構７が構成されている。The socket 3 is formed into a substantially cylindrical shape with a diameter one size smaller than the inner diameter of the wrench body 2, and is inserted into the wrench body 2, and has a so-called ratchet mechanism 7 between it and the wrench body 2 at its base end. It is configured.
また、ソケット３の内側には互いに対向する少なくとも
１対の平坦部８，８がソケット３の長手方向に連続して
形成されている。Further, on the inside of the socket 3, at least one pair of flat portions 8, 8 facing each other are formed continuously in the longitudinal direction of the socket 3.
ねじ性力角棒４はソケット３に挿入可能な略円柱形状に
形成され、その表面にはレンチ本体２のねじ孔６に螺合
可能な雄ねじ部９とソケット３の平坦部８．８と当接可
能な少なくとも１対の平坦部１０．１０がねじ付置角棒
４の長手方向に連続して形成されている。The threaded force square rod 4 is formed into a substantially cylindrical shape that can be inserted into the socket 3, and has a male threaded portion 9 that can be screwed into the screw hole 6 of the wrench body 2 and a flat portion 8.8 of the socket 3 on its surface. At least one pair of contactable flat portions 10.10 are formed continuously in the longitudinal direction of the threaded square rod 4.
そして、ねじ付置角棒４はその基端側よりレンチ本体２
のねじ孔６に螺合され、且つソケット３の中に挿入され
ている。Then, the screwed square rod 4 is inserted into the wrench body 2 from its base end.
is screwed into a screw hole 6 and inserted into the socket 3.
尚、ねじ性力角棒４の雄ねじ部９と後述するコネクター
１４のねじピッチは略同じであることが望ましい。Incidentally, it is desirable that the thread pitch of the male threaded portion 9 of the threaded force square rod 4 and the thread pitch of the connector 14, which will be described later, be approximately the same.
かかる場合、ソケット３とねじ性力角棒４は平坦部８と
１０とが当接しあっていることにより同じ方向にしか回
転できないようになっている。In such a case, the socket 3 and the threaded force angle rod 4 can only rotate in the same direction because the flat portions 8 and 10 are in contact with each other.
このような構成に於いて、ハンドル５を持ってレンチ本
体２を矢印方向（第１図参照）に回すとラチェット機構
７の働きにより、ソケット３及びねじ付置角棒４はハン
ドル５の回転力を受けてレンチ本体２と共に矢印方向に
回る（第１図参照）。In this configuration, when the wrench body 2 is rotated in the direction of the arrow by the handle 5 (see Fig. 1), the socket 3 and the threaded angle rod 4 absorb the rotational force of the handle 5 due to the action of the ratchet mechanism 7. It rotates in the direction of the arrow along with the wrench body 2 (see Fig. 1).
一方、ねじ付置角棒４の回転を阻止した状態でレンチ本
体２を反対方向に回すとラチェット機ｔＪｌｉ７の働き
により、ソケット３及びねじ付置角棒４は何ら回転力を
受けずレンチ本体２と共に回らないが、ねじ付置角棒４
がねじ孔６と雄ねじ部９との働きにより、ねじ孔６の奥
、すなわちソケット３の奥に挿入される。On the other hand, when the wrench body 2 is turned in the opposite direction while the rotation of the threaded square rod 4 is blocked, the socket 3 and the threaded square rod 4 do not receive any rotational force and rotate together with the wrench body 2 due to the action of the ratchet device tJli7. No, but screwed square rod 4
is inserted deep into the threaded hole 6, that is, into the socket 3, by the action of the threaded hole 6 and the male threaded portion 9.
したがって、ハンドル５を繰り返し前後に回すと、ハン
ドル５の矢印方向への回転によりねし性力角棒４に回転
力が伝えられ、ハンドル５の反対方向の回転によりねじ
付置角棒４がソケット３の奥に挿入される。Therefore, when the handle 5 is repeatedly turned back and forth, the rotation of the handle 5 in the direction of the arrow transmits rotational force to the threaded square rod 4, and the rotation of the handle 5 in the opposite direction causes the threaded square rod 4 to be transferred to the socket 3. inserted deep inside.
このようなラチェットレンチ■の機構により連結ボルト
の締付けを行うことができる。The connecting bolt can be tightened using the mechanism of the ratchet wrench (2).
続いて、ラチェットレンチ１による立体トラスの組み立
て方法を説明すると、立体トラスを構成する単材１１端
部のノーズコーン１２を前記単打１１どうしを連結する
球継手１３に突き付ける。Next, a method for assembling a three-dimensional truss using the ratchet wrench 1 will be described. The nose cone 12 at the end of the single members 11 constituting the three-dimensional truss is pressed against the ball joint 13 that connects the single members 11.
続いて、当該法継手１３の貫通孔１３ａの中にラチェッ
トレンチ１を挿入すると共に当該ラチェットレンチ１の
ねじ付置角棒４の先端部を前記ノーズコーン１２の中に
組み込まれたコネクター１４先端の六角孔１４ａに挿入
する。Next, insert the ratchet wrench 1 into the through hole 13a of the joint 13, and insert the tip of the threaded square rod 4 of the ratchet wrench 1 into the hexagonal end of the connector 14 built into the nose cone 12. Insert into hole 14a.
続いて、ラチェットレンチｌによって前記コネクター１
４を球継手１３のねじ孔１３ｂにその奥に引き込むよう
に螺合する。Then, use the ratchet wrench l to tighten the connector 1.
4 is screwed into the screw hole 13b of the ball joint 13 so as to be pulled deep into the screw hole 13b.
かがる場合、コネクター１４を球継手１３側に徐々に締
め付けても、これと同時にねじ性力角棒４はソケット３
の中に徐々に挿入され、突出部分が徐々に短くなる為、
締付は終了後、ラチェットレンチ１を球継手１３の貫通
孔１３ａの中から簡単に引き抜くことができる。When tightening, even if the connector 14 is gradually tightened toward the ball joint 13, the threaded force square rod 4 is tightened at the same time as the socket 3.
It is gradually inserted into the body, and the protruding part gradually becomes shorter.
After tightening is completed, the ratchet wrench 1 can be easily pulled out from the through hole 13a of the ball joint 13.
したがって、最初から最後まで同じラチェットレンチを
使用することができる。Therefore, the same ratchet wrench can be used from beginning to end.
尚、このラチェットレンチを使ってコネクタ１４を緩め
る場合には、コネクター１４をノズコーン１２の中に徐
々にねじ込むように回す必要がある為、ねじ伸直角棒４
先端の突出長さも当然これに伴って徐々に長くなる構成
になっでいる。When loosening the connector 14 using this ratchet wrench, it is necessary to gradually screw the connector 14 into the nozzle cone 12.
Naturally, the protruding length of the tip also gradually increases accordingly.
