問題は、ボールチャック１５からワイヤ１をいかにして取り外すかにある。この点に関し、従来はホルダー２３の先端部をケース２２の通口２８の外側に導出し、ホルダー先端部を押してホルダー２３の全体をテーパー面２１の大径端側へばね２６の付勢力に抗して移動させることにより、ワイヤ１のクランプ力を解除していた。   The problem is how to remove the wire 1 from the ball chuck 15. In this regard, conventionally, the tip of the holder 23 is led out of the through hole 28 of the case 22 and the tip of the holder is pushed to push the entire holder 23 toward the large-diameter end of the tapered surface 21 against the urging force of the spring 26. By moving the wire 1, the clamping force of the wire 1 is released.

しかし、従来のクランプ解除方式では、いたずらを受けてワイヤが取り外されたり、弛んだ状態にされたりする。これを防ごうとすると、ボールチャック１５側の構造が複雑化していた。   However, in the conventional clamp release method, the wire is removed or slackened due to mischief. To prevent this, the structure on the ball chuck 15 side becomes complicated.

そこで、本発明の目的は、ボールチャックの設置状態において部外者ではケースに内蔵のホルダーをクランプ解除操作ができないようにして、いたずらによるワイヤの取り外しなどを防止するにある。その一方で、本発明の目的は、事情を知る者にとってワイヤクランプの解除操作が手軽に行える専用の治具を提供することにある。   Accordingly, it is an object of the present invention to prevent an outsider from performing a clamp release operation on a holder built in a case in a state where a ball chuck is installed, and to prevent a wire from being removed by mischief. On the other hand, an object of the present invention is to provide a dedicated jig that allows a person who knows the situation to easily release the wire clamp.

本発明は、前述のボールチャックを対象とし、ボールチャック１５によるワイヤ１のクランプ固定を解除するための治具３４が、ケース２２の通口２８からケース２２内に差し込まれて、ホルダー２３をテーパー面２１の大径端側へ移動させる軸部３５と、軸部３５の一端に張り出したフランジ３６と有し、軸部３５およびフランジ３６の双方にわたってワイヤ１を受け入れる溝３７が設けられていることを特徴とする。   In the present invention, the jig 34 for releasing the clamp fixing of the wire 1 by the ball chuck 15 is inserted into the case 22 from the through hole 28 of the case 22, and the holder 23 is tapered. A shaft portion 35 that moves to the large-diameter end of the surface 21 and a flange 36 that protrudes from one end of the shaft portion 35, and a groove 37 that receives the wire 1 is provided over both the shaft portion 35 and the flange 36. It is characterized by.

本発明によれば、張られたワイヤ１にこれの外側から治具３４の溝３７を嵌合し、ワイヤ１に沿って治具３４を滑らせ、軸部３５をケース２２の通口２８に差し込み、フランジ３６を手にして軸部３５の差し込み端でホルダー２３をテーパー面２１の大径端側へばね２６の付勢力に抗して押し込むことにより、ホルダー２３のボール２４・２５によるワイヤのクランプを解除できる。したがって、本発明のワイヤ取り外し治具さえあれば、ボールチャック１５で緊張状態に張られたワイヤ１でも、簡単かつ確実にそのワイヤクランプを解除操作できる。ボールチャック１５側にはクランプ解除用部材を備えていないので、構造が複雑化せず、いたずらを受けてワイヤ１が取り外されるといった事態もよく防止できる。   According to the present invention, the groove 37 of the jig 34 is fitted into the stretched wire 1 from the outside thereof, the jig 34 is slid along the wire 1, and the shaft 35 is inserted into the opening 28 of the case 22. The holder 23 is pushed into the large-diameter end of the tapered surface 21 at the insertion end of the shaft portion 35 against the urging force of the spring 26 with the flange 36 as a hand. The clamp can be released. Therefore, with the wire removal jig of the present invention, even with the wire 1 tensioned by the ball chuck 15, the wire clamp can be easily and reliably released. Since the ball chuck 15 is not provided with a clamp releasing member, the structure is not complicated, and a situation in which the wire 1 is removed due to mischief can be prevented well.

図１ないし図７はワイヤ緊張装置の実施例を示す。図３において符号１はステンレス材製のワイヤ、２はワイヤ１の一端を固定保持するワイヤ固定具、３はワイヤ１の他端に設けたワイヤ緊張具であり、これらの部材でワイヤ緊張装置が構成されている。   1 to 7 show an embodiment of the wire tensioning device. In FIG. 3, reference numeral 1 denotes a wire made of stainless steel, 2 denotes a wire fixing tool for fixing and holding one end of the wire 1, and 3 denotes a wire tightening tool provided at the other end of the wire 1. It is configured.

図２においてワイヤ固定具２は、ワイヤ１の端部にかしめ固定したエンド金具４を受け止める圧縮ばね５およびスラストベアリング６と、これら三者４・５・６を収容する有底筒状のケース７と、ケース７の開口端にねじ８を介して装着した取付金具９とからなる。ケース７、取付金具９およびエンド金具４はそれぞれステンレス鋼材で形成する。圧縮ばね５の一端に深絞り加工したキャップ状の受金具１０を内嵌装着し、この受金具１０でエンド金具４を受け止めている。圧縮ばね５の他端はケース７の内奥端に装填したスラストベアリング６で受け止める。スラストベアリング６は、圧縮ばね５を受け止めるラッパ状の保持リング６ａと、多数個のステンレス鋼材製のボール６ｂとからなる。ケース７の筒端にはワイヤ通口７ａを設けてある。   In FIG. 2, a wire fixing device 2 includes a compression spring 5 and a thrust bearing 6 for receiving an end fitting 4 caulked and fixed to an end of the wire 1, and a bottomed cylindrical case 7 for accommodating these three members 4.5. And a mounting bracket 9 attached to the open end of the case 7 via a screw 8. The case 7, the mounting metal 9 and the end metal 4 are each made of stainless steel. A cap-shaped metal fitting 10 that has been deep drawn is fitted inside one end of the compression spring 5, and the metal fitting 10 receives the end metal fitting 4. The other end of the compression spring 5 is received by a thrust bearing 6 mounted on the inner rear end of the case 7. The thrust bearing 6 comprises a trumpet-shaped holding ring 6a for receiving the compression spring 5, and a number of stainless steel balls 6b. A wire opening 7a is provided at the cylindrical end of the case 7.

取付金具９は、周面に雄ねじが形成された有底筒状のキャップ１１と、キャップ１１をブラケット１２に締結するボルト１３とからなる。ブラケット１２は四角形、六角形、八角形等の角軸で形成してあり、その一端を取付対象に予め溶接しておく。キャップ１１の底壁にはブラケット１２に外嵌できる同じ断面形状の係合穴１４を通設する。キャップ１１をブラケット１２に外嵌した後、ボルト１３をキャップ１１の開口面の側からブラケット１２に設けたねじ穴にねじ込むことにより、キャップ１１を脱落不能に受け止めることができる。ボルト１３は六角穴付きボルトからなり、頭部の直径寸法を係合穴１４の対辺長よりも大きく設定する。先のケース７の開口側内面には、キャップ１１の雄ねじに対応する雌ねじが形成してある。   The mounting bracket 9 includes a bottomed cylindrical cap 11 having a male screw formed on a peripheral surface, and a bolt 13 for fastening the cap 11 to a bracket 12. The bracket 12 is formed by a square axis such as a square, a hexagon, an octagon, or the like, and one end of the bracket 12 is previously welded to a mounting object. An engagement hole 14 having the same cross-sectional shape that can be fitted to the bracket 12 is provided in the bottom wall of the cap 11. After the cap 11 is fitted onto the bracket 12, the bolt 11 is screwed into the screw hole provided on the bracket 12 from the side of the opening surface of the cap 11, so that the cap 11 can be received without falling off. The bolt 13 is formed of a hexagon socket head bolt, and the diameter of the head is set to be larger than the length of the opposite side of the engagement hole 14. A female screw corresponding to the male screw of the cap 11 is formed on the inner surface on the opening side of the case 7.

図１においてワイヤ緊張具３は、ワイヤ１の遊端をクランプ固定するボールチャック１５と、ボールチャック１５のケース２２の開口端に緊張ねじ１７を介してねじ込んだ取付金具１９とからなる。   In FIG. 1, the wire tensioner 3 includes a ball chuck 15 for clamping and fixing the free end of the wire 1, and a mounting bracket 19 screwed into the open end of the case 22 of the ball chuck 15 via a tension screw 17.

ボールチャック１５は、内面にボール操作用のテーパー面２１を有する筒状のケース２２と、ケース２２内に組み込んだコーン形状のホルダー２３と、ホルダー２３で支持される大小２組のボール２４・２５と、ホルダー２３をテーパー面２１の小径端へ向かってクランプ付勢する圧縮コイル形のばね２６などで構成してあり、従来のボールチャックに比べて以下の点が異なる。ホルダー２３をばね２６の付勢力に抗してクランプ解除操作するための操作部を省略し、ホルダー２３の全体をケース２２の内部に位置させる。ケース２２の外面からホルダー２３を操作できないようにし、いたずらの余地を無くすためである。ホルダー２３には、その軸心に沿ってワイヤ通口３２を通設する。大小のボール２４・２５はそれぞれ３個を一組にして設けてあり、ワイヤ１を強固にクランプ固定できる。   The ball chuck 15 includes a cylindrical case 22 having a tapered surface 21 for ball operation on the inner surface, a cone-shaped holder 23 incorporated in the case 22, and two large and small sets of balls 24 and 25 supported by the holder 23. And a compression coil spring 26 for urging the holder 23 toward the small-diameter end of the tapered surface 21. The following points are different from the conventional ball chuck. An operation unit for releasing the clamp of the holder 23 against the urging force of the spring 26 is omitted, and the entire holder 23 is positioned inside the case 22. This is to make it impossible to operate the holder 23 from the outer surface of the case 22 and to leave room for mischief. The holder 23 is provided with a wire passage 32 along the axis thereof. Each of the large and small balls 24 and 25 is provided as a set of three, and the wire 1 can be firmly clamped.

ケース２２内に、ボール２４・２５が装填されたホルダー２３とばね２６を組み、ケース２２の内面に嵌め込んだ止め輪２７でばね２６の大径端を受け止めて、ボールチャック１５を一個のユニット部品化する。ケース２２の内奥端の中央には通口２８を通設し、ケース外周面に締結操作用の操作部２９を設ける。操作部２９はテーパー面２１に臨むケース外周面に設けた平行な一対の操作溝で形成する（図６参照）。ケース内面の開口端寄りには、緊張ねじ１７を構成する雌ねじ１７ｂを形成する（図３参照）。   The case 23 is assembled with a holder 23 loaded with balls 24 and 25 and a spring 26, and a large diameter end of the spring 26 is received by a retaining ring 27 fitted on the inner surface of the case 22, and the ball chuck 15 is connected to one unit. Make parts. A through hole 28 is provided in the center of the inner rear end of the case 22, and an operating portion 29 for fastening operation is provided on the outer peripheral surface of the case. The operation portion 29 is formed by a pair of parallel operation grooves provided on the outer peripheral surface of the case facing the tapered surface 21 (see FIG. 6). A female screw 17b constituting the tension screw 17 is formed near the opening end of the case inner surface (see FIG. 3).

取付金具１９は先に説明した取付金具９と同じ部品であって、その周面に上記の雌ねじ１７ｂに対応する雄ねじ１７ａを形成する。他は取付金具９と同じであるので同一部材には同じ符号を付して説明を省略する。なお、ケース２２、ホルダー２３および連結金具９・１９はそれぞれステンレス鋼材で形成してある。緊張ねじ１７のねじ込み代Ｓは、圧縮ばね５の圧縮代と同じか、これより大きく設定する。   The mounting bracket 19 is the same component as the mounting bracket 9 described above, and has a male screw 17a corresponding to the female screw 17b formed on the peripheral surface thereof. Other components are the same as those of the mounting bracket 9, and therefore, the same members are denoted by the same reference numerals and description thereof will be omitted. The case 22, the holder 23, and the connection fittings 9 and 19 are each formed of a stainless steel material. The screwing allowance S of the tension screw 17 is set to be equal to or larger than the compression allowance of the compression spring 5.

ボール２４・２５によるクランプ力が一定値を越えるときに、ワイヤ１の撚りが解離されてクランプ力が急激に低下するのを防ぐために、大小２組のボール２４・２５のうち、小径のボール２５のみをステンレス鋼材で形成する。大径のボール２４は黄銅で形成し、電気防蝕のためにニッケルあるいはクロームメッキを施す。さらに、小径のボール２５のチャッキング径を基準にして、大径のボール２４のチャッキング径を、先のチャッキング径より僅かに大きく設定する。小径のボール２５がワイヤ１の周面に食い込み、ワイヤ１が解離し始める状態のとき、大径のボール２４がワイヤ１の表面に塑性変形しながら密着し、それ以上にワイヤ１の解離が進行するのを防ぐためである。この実施例では、小径のボール２５によるクランプ力を１００とするとき、大径のボール２４のクランプ力が８０前後になるように、各ボール２４・２５のチャッキング径を設定した。   When the clamping force by the balls 24 and 25 exceeds a certain value, in order to prevent the twist of the wire 1 from being dissociated and the clamping force from abruptly decreasing, the small-diameter ball 25 of the two large and small sets of balls 24 and 25 is used. Only made of stainless steel. The large-diameter ball 24 is formed of brass and plated with nickel or chrome for electrical corrosion protection. Further, based on the chucking diameter of the small-diameter ball 25, the chucking diameter of the large-diameter ball 24 is set slightly larger than the previous chucking diameter. When the small-diameter ball 25 bites into the peripheral surface of the wire 1 and the wire 1 starts to be dissociated, the large-diameter ball 24 adheres to the surface of the wire 1 while being plastically deformed, and the dissociation of the wire 1 proceeds further. This is to prevent them from doing so. In this embodiment, the chucking diameter of each of the balls 24 and 25 is set so that the clamping force of the large-diameter ball 24 is about 80 when the clamping force of the small-diameter ball 25 is 100.

次にワイヤ緊張装置を用いて、図７に示すように隣接する支柱３１・３１の間にワイヤ１を張り渡す場合の作業手順を説明する。ブラケット１２は各支柱３１に予め溶接しておく。まず、取付金具９・１９をそれぞれの開口面が対向する状態でブラケット１２に組み、ボルト１３を完全に締め込む。次に、図３に示すようにケース２２のねじ山の数条をキャップ１１のねじ溝にかみ合わせ、ケース２２のワイヤ通口２８からワイヤ１をホルダー２３内に差し込んで、ワイヤ１の遊端をボールチャック１５でクランプ固定する。同様にワイヤ固定具２のケース７を取付金具９にねじ込み、図２に示すようにキャップ１１がケース７内に入り込んでしまうまでケース７をねじ込む。このときは、圧縮ばね５が圧縮変形するので、ワイヤ固定金具２を容易にねじ込み操作できる。   Next, an operation procedure when the wire 1 is stretched between the adjacent columns 31 as shown in FIG. 7 using the wire tensioning device will be described. The bracket 12 is welded to each support 31 in advance. First, the mounting brackets 9 and 19 are assembled to the bracket 12 with their opening surfaces facing each other, and the bolt 13 is completely tightened. Next, as shown in FIG. 3, several threads of the thread of the case 22 are engaged with the thread grooves of the cap 11, and the wire 1 is inserted into the holder 23 through the wire opening 28 of the case 22, and the free end of the wire 1 is connected. It is clamped and fixed by the ball chuck 15. Similarly, the case 7 of the wire fixing tool 2 is screwed into the mounting bracket 9, and the case 7 is screwed until the cap 11 enters the case 7 as shown in FIG. At this time, since the compression spring 5 is compressed and deformed, the wire fixing fitting 2 can be easily screwed.

上記のようにワイヤ１を仮張設した後、ケース２２の操作部２９にスパナ等の工具を当てがって、ケース２２を取付金具１９にねじ込み、ワイヤ１を徐々に緊張させる。最終的には、圧縮ばね５が全圧縮するまでケース２２をねじ込み操作して、ワイヤ１にたるみが生じる余地を無くす。なお、圧縮ばね５の全圧縮状態は、ケース２２のねじ込み力が急激に増加することで知ることができる。もちろん、上記とは異なる手順でワイヤ１を張り渡してもよい。先に述べた圧縮ばね５の圧縮代とは、ワイヤ１を仮張設したのち圧縮ばね５が全圧縮するまでのたわみ量、あるいは受金具１０の筒端がスラストベアリング６に接当するまでの圧縮ばね５のたわみ量のいずれかを意味する。   After the wire 1 is temporarily tensioned as described above, a tool such as a wrench is applied to the operation unit 29 of the case 22, the case 22 is screwed into the mounting bracket 19, and the wire 1 is gradually tensioned. Finally, the case 22 is screwed until the compression spring 5 is fully compressed, so that there is no room for the wire 1 to be slackened. Note that the fully compressed state of the compression spring 5 can be known by a sharp increase in the screwing force of the case 22. Of course, the wire 1 may be stretched in a procedure different from the above. The above-mentioned compression allowance of the compression spring 5 means the amount of deflection until the compression spring 5 is fully compressed after the wire 1 is temporarily stretched, or the amount of deflection until the cylinder end of the receiving member 10 comes into contact with the thrust bearing 6. It means any of the deflection amounts of the compression spring 5.

ワイヤ固定具２にスラストベアリング６が内蔵してあるので、ワイヤ２が各ケース７・２２のねじ込み操作によってねじり変形するのを確実に防止できる。ワイヤ１を張り渡した状態では、ホルダー２３がケース２２で覆い隠されて操作できないので、いたずらの余地を皆無にできる。ボルト１３がキャップ１１内に収容されることも、いたずらを排除することに役立っている。   Since the thrust bearing 6 is built in the wire fixture 2, it is possible to reliably prevent the wire 2 from being torsionally deformed by the screwing operation of each of the cases 7, 22. In a state where the wire 1 is stretched, the holder 23 is covered and hidden by the case 22 and cannot be operated, so that there is no room for mischief. The fact that the bolt 13 is accommodated in the cap 11 also helps to eliminate mischief.

張り渡したワイヤ１を取り外す必要がある場合には、図５に示す本発明のワイヤ取り外し治具３４でホルダー２３をクランプ解除する。ワイヤ取り外し治具３４は軸部３５の一端にフランジ３６を張り出して構成してあり、軸部３５およびフランジ３６の双方にわたってワイヤ１を受け入れる溝３７を設ける。軸部３５をケース２２の通口２８からケース内へ差し込み、ワイヤ取り外し治具３４の全体をケース内方へ押し込むと、ホルダー２３がテーパー面２１の大径端側へ移動するので、各ボール２４・２５によるクランプ力を解放してワイヤ１をボールチャック１５から取り外すことができる。   When it is necessary to remove the stretched wire 1, the holder 23 is released from the clamp by the wire removing jig 34 of the present invention shown in FIG. The wire removing jig 34 is formed by projecting a flange 36 at one end of a shaft 35, and has a groove 37 for receiving the wire 1 over both the shaft 35 and the flange 36. When the shaft portion 35 is inserted into the case through the opening 28 of the case 22 and the entire wire removing jig 34 is pushed inward, the holder 23 moves to the large-diameter end side of the tapered surface 21. The wire 1 can be detached from the ball chuck 15 by releasing the clamping force of 25.

上記の実施例以外に、ボール２５はステンレス鋼材以外の鋼材や鋼合金で形成することができる。ボール２４は黄銅以外の銅合金や、鋼材より軟質の金属を適用できる。必要があれば、小径のボール２５を黄銅等の金属で形成し、大径のボール２４を鋼材で形成することができる。操作部２９は溝として形成する必要はなく、浅い穴や平行な平坦面で形成することができる。本発明のボールチャックは、ワイヤ緊張装置以外のワイヤクランプや、小径棒材のクランプとして適用することができる。スラストベアリング６は、市販のベアリングやスリップワッシャを流用できる。   In addition to the above embodiment, the ball 25 can be formed of a steel material or a steel alloy other than a stainless steel material. For the ball 24, a copper alloy other than brass or a metal softer than steel can be used. If necessary, the small-diameter ball 25 can be formed of a metal such as brass, and the large-diameter ball 24 can be formed of a steel material. The operation portion 29 does not need to be formed as a groove, but can be formed with a shallow hole or a parallel flat surface. INDUSTRIAL APPLICABILITY The ball chuck of the present invention can be applied as a wire clamp other than a wire tensioning device or a clamp for a small-diameter bar. As the thrust bearing 6, a commercially available bearing or slip washer can be used.
