Description

本考案は、例えば、建設、建築、荷役、構内作業等々の各種作業現場で吊り作業用として使用される旋回自在な吊持具に係り、特に、旋回動作時の摩擦抵抗を少なくした旋回吊持具に関する。   The present invention relates to a swingable lifting tool used for suspension work at various work sites such as construction, construction, cargo handling, and on-site work, and in particular, swinging suspension with reduced frictional resistance during a swinging operation. Concerning ingredients.

吊り作業用の吊りピースとして、従来から、アイボルトが各種作業現場で広く使用されている。このアイボルトは、そのボルト部分を吊持対象物に対してねじ込むかナットで締結することによって固定状態に取付られ、単なる吊り作業だけでなく重量物の引き起しや反転作業等にも使用されることがある。しかし、アイボルトは、吊持対象物に対して締結状態に固定されるため吊り荷重の方向が変化すると変形しやすいという難点があった。   Conventionally, eyebolts have been widely used at various work sites as suspension pieces for suspension work. This eyebolt is mounted in a fixed state by screwing the bolt part into the object to be suspended or fastened with a nut, and is used not only for suspending work but also for lifting or reversing heavy objects. Sometimes. However, since the eyebolt is fixed in a fastened state with respect to the suspended object, there is a problem that the eyebolt is easily deformed when the direction of the suspended load is changed.

そこで、このような難点を解消するために、例えば、図７に示すような旋回連結具が提案されている（例えば、特許文献１参照）。この旋回連結具は、揺動式連結部材（リンク）３の折り曲げられた脚部先端に案内突起３ａ，３ａを設け、この揺動式連結部材３の取付けを容易とするために、回転部材（ハウジング）２の開口部を吊持対象物２０の側に切り欠いたこと、及び、揺動式連結部材３が取り付け回転部材２を挿通させるアンカーユニット（締結部材）１が、ボルト状の締結部材であることを特徴とし、アンカーユニット１には、鍔付きのアッパーブッシュ５とロアーブッシュ１５が嵌挿されている。なお、ｅはアンカーユニット１に係止される脱落防止用の止め輪である。   Therefore, in order to eliminate such difficulties, for example, a swivel connector as shown in FIG. 7 has been proposed (see, for example, Patent Document 1). This swivel connector is provided with guide protrusions 3a, 3a at the bent leg end of the swinging connection member (link) 3 so that the swinging connection member 3 can be easily mounted. The opening portion of the housing 2 is cut out to the side of the object 20 to be held, and the anchor unit (fastening member) 1 through which the swinging connecting member 3 inserts the rotating member 2 is a bolt-like fastening member. The anchor unit 1 is fitted with a hooked upper bush 5 and a lower bush 15. In addition, e is a retaining ring for preventing falling off that is locked to the anchor unit 1.

このような構成により、アンカーユニット１を吊持対象物２０に規定トルクでねじ込み固定しても、揺動式連結部材３は、取付面に対して１８０度、取付軸に対して３６０度自由に回転するため、吊持対象物２０をどの方向から吊り上げても揺動式連結部材３が柔軟に回転して安全に吊り上げることができ、また、揺動式連結部材３を倒すことができるため、吊持対象物２０に取り付けた状態でもスペースを要することなく積み重ねも可能であるとされている。   With such a configuration, even if the anchor unit 1 is screwed and fixed to the suspension target object 20 with a specified torque, the oscillating connecting member 3 can freely rotate 180 degrees with respect to the mounting surface and 360 degrees with respect to the mounting shaft. Since it rotates, the swinging connection member 3 can be flexibly rotated and lifted safely regardless of the direction in which the suspension object 20 is lifted, and the swinging connection member 3 can be brought down. It is said that even when attached to the object to be suspended 20, stacking is possible without requiring space.

特許第２７６１６６０号公報Japanese Patent No. 2761660

しかし、上記従来の旋回連結具では、吊持対象物２０の引き起し作業や反転作業を行う際に、吊り荷重の方向が変化すると、揺動式連結部材３、回転部材２、アッパーブッシュ５の間で発生する摩擦力によって連れまわりトルクが発生して、アンカーユニット１が緩むことがあった。つまり、この旋回連結具は、アッパーブッシュ５の鍔部５ａの下面と回転部材２の座面２ａとの面接触で荷重を受けるため、その摩擦抵抗がアンカーユニット１のボルト締め付けトルクよりも大になることがあった。また、その大きな摩擦抵抗によって、耳障りな摩擦音が発生することもあった。   However, in the above-described conventional swivel coupler, if the direction of the suspension load changes when the lifting object 20 is lifted or reversed, the swinging coupling member 3, the rotating member 2, and the upper bush 5 The anchor unit 1 may be loosened due to the accompanying torque generated by the frictional force generated between the two. In other words, the swivel coupler receives a load due to surface contact between the lower surface of the flange portion 5a of the upper bush 5 and the seating surface 2a of the rotating member 2, so that the frictional resistance is larger than the bolt tightening torque of the anchor unit 1. There was. In addition, an awkward frictional sound may be generated due to the large frictional resistance.

本考案は、このような実情に鑑みてなされ、旋回動作時の抵抗が少なく、旋回に伴う摩擦音の発生を少なくした旋回吊持具を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a swivel holding tool that has a low resistance during a swivel operation and that generates less frictional noise associated with the swivel.

（１）本考案に係る旋回吊持具は、吊持対象物２０に締結固定される締結部材１と、

A rolling bearing 4 disposed between the fastening member 1 and the housing 2 for receiving a suspension load is provided.

このような構成によれば、吊り荷重が締結部材１とハウジング２の間に配設されたころがり軸受け４によって受けられるため、吊り荷重の方向が変化する場合にも、締結部材１がハウジング２に対して円滑に回転するので、連れまわりトルクの発生が低く抑えられ、吊持対象物２０に対する締結部材１の固定状態は安定に維持される。また、ころがり軸受け４では、面接触で荷重を受ける従来の旋回連結具のような大きな摩擦音（異音）は発生せず、吊り作業時の騒音が低減され対環境性も良好となる。なお、締結部材１は吊持対象物２０に対してねじ込みによって固定されてもよく、ナットの締結によって固定されてもよい。   According to such a configuration, since the suspension load is received by the rolling bearing 4 disposed between the fastening member 1 and the housing 2, the fastening member 1 is attached to the housing 2 even when the direction of the suspension load changes. On the other hand, since it rotates smoothly, the generation | occurrence | production of accompanying torque is suppressed low and the fixed state of the fastening member 1 with respect to the suspension target object 20 is maintained stably. In addition, the rolling bearing 4 does not generate a large frictional noise (abnormal noise) unlike the conventional swivel coupler that receives a load by surface contact, and the noise during suspension work is reduced and the environmental resistance is improved. In addition, the fastening member 1 may be fixed with screwing with respect to the suspension target object 20, and may be fixed by fastening of a nut.

（２）前記ころがり軸受け４は、スラストベアリングからなるものであってもよい。このように、既存のスラストベアリングを用いれば、調達が容易になる利点がある。なお、スラストベアリングは単式平面座形又は複式平面座形の他、自動調心スラストころ軸受けも使用することができる。 (2) The rolling bearing 4 may be a thrust bearing. Thus, if an existing thrust bearing is used, there is an advantage that procurement becomes easy. As the thrust bearing, a self-aligning thrust roller bearing can be used in addition to the single plane seat type or the double plane seat type.

（３）前記ハウジング２は、下部開放の略中空円筒状に形成され、その中央には、フランジ付きのブッシュ５を挿通させるための中央孔部２ａが形成され、前記ころがり軸受け４は、前記ブッシュ５のフランジ部５ａと、前記ハウジング２に形成された着座部２ｂの間に配設されてもよい。このようにすれば、ころがり軸受け４の着脱交換が容易となる。 (3) The housing 2 is formed in a substantially hollow cylindrical shape with an open bottom, and a central hole portion 2a for inserting a flanged bushing 5 is formed at the center thereof. 5 may be disposed between the flange portion 5 a and the seat portion 2 b formed on the housing 2. In this way, the rolling bearing 4 can be easily attached and detached.

（４）前記ブッシュ５のフランジ部５ａの外周には、前記ころがり軸受け４の回転部分を覆うカバー部５ｃが形成されてもよい。このようにすれば、ころがり軸受け４の回転部分への異物の侵入が阻止されるため、締結部材１とハウジング２の間で円滑な回転動作を維持することができ、耐久性も向上する。 (4) A cover portion 5 c that covers the rotating portion of the rolling bearing 4 may be formed on the outer periphery of the flange portion 5 a of the bush 5.

（５）前記ハウジング２の円筒状部の両側下部には、前記リンク部材３の内側に折曲された脚部３ｂ，３ｂを回動自在に嵌め込むための下向き開放状の凹部２ｃ，２ｃが形成されてもよい。このようにすれば、リンク部材３の内側に折曲された脚部３ｂ，３ｂをハウジング２に容易に嵌め込むことができ、旋回吊持具の組み付け作業性が向上する。 (5) Downwardly open recesses 2c and 2c for rotatably fitting the leg portions 3b and 3b bent inside the link member 3 are provided at the lower portions on both sides of the cylindrical portion of the housing 2. It may be formed. If it does in this way, the leg parts 3b and 3b bent inside the link member 3 can be easily engage | inserted in the housing 2, and the assembly workability | operativity of a rotation suspension tool will improve.

（６）前記ころがり軸受け４は、前記ハウジング２に形成される上向きの円周溝２ｄと、前記締結部材１に抜け止め状態に嵌め込まれるブッシュ５のフランジ部５ａに形成される下向きの円周溝５ｄと、の間に複数の鋼球６を遊嵌させて構成されてもよい。このようにすれば、吊り荷重の方向が変化する場合にも、スラストベアリングと同様に締結部材１とハウジング２の間で円滑な回転動作を得ることができ、連れまわりトルクの発生が低く抑えられ、吊持対象物２０に対する締結部材１の固定状態は安定に維持される。また、面接触で荷重を受ける従来の旋回連結具のような大きな摩擦音（異音）は発生せず、吊り作業時の騒音が低減され対環境性も良好となる。そして、スラストベアリングをそのまま使用する場合よりもコンパクトに形成することができる。 (6) The rolling bearing 4 includes an upward circumferential groove 2d formed in the housing 2 and a downward circumferential groove formed in the flange portion 5a of the bush 5 fitted in the fastening member 1 in a retaining state. A plurality of steel balls 6 may be loosely fitted between 5d and 5d. In this way, even when the direction of the suspension load changes, a smooth rotation operation can be obtained between the fastening member 1 and the housing 2 in the same manner as the thrust bearing, and the generation of follow-up torque can be kept low. And the fixed state of the fastening member 1 with respect to the suspension target object 20 is maintained stably. In addition, a large frictional noise (abnormal noise) unlike a conventional swivel connector that receives a load due to surface contact does not occur, noise during suspension work is reduced, and environmental resistance is improved. And it can form compactly compared with the case where a thrust bearing is used as it is.

（７）前記ブッシュ５のフランジ部５ａと前記ハウジング２の間に形成される隙間ｓを覆うための孔付きカバー７を前記締結部材１に嵌め込んでもよい。このようにすれば、回転部分への異物の侵入が阻止されるため、締結部材１とハウジング２の間で円滑な回転動作を維持することができ、耐久性も向上する。 (7) A cover 7 with a hole for covering a gap s formed between the flange portion 5 a of the bush 5 and the housing 2 may be fitted into the fastening member 1.

（８）前記ころがり軸受け４は、前記締結部材１に抜け止め状態に嵌め込まれるワッシャ８の下面と、前記締結部材１に抜け止め状態に嵌め込まれるブッシュ５の前記ハウジング２に着座するフランジ部５ａに形成される上向きの円周溝５ｅと、の間に複数の鋼球６を遊嵌させて構成されてもよい。吊り荷重の方向が変化する場合にも、スラストベアリングと同様に締結部材１とハウジング２の間で円滑な回転動作を得ることができ、連れまわりトルクの発生が低く抑えられ、吊持対象物２０に対する締結部材１の固定状態は安定に維持される。また、面接触で荷重を受ける従来の旋回連結具のような大きな摩擦音（異音）は発生せず、吊り作業時の騒音が低減され対環境性も良好となる。そして、スラストベアリングをそのまま使用する場合よりもコンパクトに形成することができる。 (8) The rolling bearing 4 is provided on a lower surface of a washer 8 fitted in the retaining member 1 in a retaining state and a flange portion 5a seated on the housing 2 of a bush 5 fitted in the retaining member 1 in a retaining state. A plurality of steel balls 6 may be loosely fitted between the upward circumferential groove 5e to be formed. Even when the direction of the suspension load changes, a smooth rotation operation can be obtained between the fastening member 1 and the housing 2 similarly to the thrust bearing, and the generation of the accompanying torque can be suppressed to a low level. The fastening state of the fastening member 1 with respect to is maintained stably. In addition, a large frictional noise (abnormal noise) unlike a conventional swivel connector that receives a load due to surface contact does not occur, noise during suspension work is reduced, and environmental resistance is improved. And it can form compactly compared with the case where a thrust bearing is used as it is.

（９）前記ワッシャ８の外周には、前記ころがり軸受け４の回転部分を覆うカバー部８ｃが形成されてもよい。このようにすれば、ころがり軸受け４の回転部分への異物の侵入が阻止されるため、締結部材１とハウジング２の間で円滑な回転動作を維持することができ、耐久性も向上する。 (9) A cover portion 8 c that covers the rotating portion of the rolling bearing 4 may be formed on the outer periphery of the washer 8.

（１０）本考案の別の旋回吊持具は、吊持対象物２０に締結固定される締結部材１と、
前記締結部材１を回転自在に支持するためのハウジング２と、
前記ハウジング２に揺動自在に支持されるリンク部材３と、
吊り荷重を支えるために前記締結部材１と前記ハウジング２の間に配設される間装部材９と、を備え、
前記間装部材９は、前記締結部材１に抜け止め状態に嵌挿されるハードワッシャ１０と、該ハードワッシャ１０と前記ハウジング２の間に間装されるブッシュ２５からなり、前記ハードワッシャ１０とブッシュ２５の当接面は、球面加工により上凸の球面状に形成されることを特徴とする。 (10) Another swivel holding tool of the present invention includes a fastening member 1 fastened and fixed to a suspension object 20;
A housing 2 for rotatably supporting the fastening member 1;
A link member 3 swingably supported by the housing 2;
An interposing member 9 disposed between the fastening member 1 and the housing 2 to support a suspension load,
The interposing member 9 includes a hard washer 10 that is inserted into the fastening member 1 in a retaining state, and a bush 25 that is interposed between the hard washer 10 and the housing 2, and the hard washer 10 and the bush The abutment surface 25 is formed into a spherical surface that is convex upward by spherical processing.

このような構成によれば、吊り荷重を受けるための間装部材９をハードワッシャ１０とブッシュ２５で構成し、その当接面を、球面加工により上凸の球面状に形成するので、吊り荷重の方向が変化する場合にも、ハードワッシャ１０とブッシュ２５が柔軟に対応することができ、連れまわりトルクの発生を低減して吊持対象物２０に対する締結部材１の固定状態を安定に維持することができる。なお、締結部材１は吊持対象物２０に対してねじ込みによって固定されてもよく、ナットの締結によって固定されてもよい。   According to such a configuration, the interposing member 9 for receiving the suspending load is constituted by the hard washer 10 and the bush 25, and the contact surface thereof is formed into an upwardly convex spherical shape by spherical processing. The hard washer 10 and the bush 25 can flexibly cope with the change in the direction of the rotation, and the generation of the accompanying torque is reduced to stably maintain the fastening state of the fastening member 1 with respect to the suspended object 20. be able to. In addition, the fastening member 1 may be fixed with screwing with respect to the suspension target object 20, and may be fixed by fastening of a nut.

（１１）前記ハードワッシャ１０の当接面には、クロム鍍金又は亜鉛鍍金等の表面処理が施され、前記当接面の摩擦係数が０．１０〜０．１５に設定されてもよい。このようにすれば、吊り荷重の方向が変化する場合にも、ハードワッシャ１０とブッシュ２５の間の摩擦力を少なくすることができる。 (11) The contact surface of the hard washer 10 may be subjected to a surface treatment such as chrome plating or zinc plating, and the friction coefficient of the contact surface may be set to 0.10 to 0.15. In this way, the frictional force between the hard washer 10 and the bush 25 can be reduced even when the direction of the suspension load changes.

本考案の本考案に係る旋回吊持具は、フック等を掛けるためのリンク部材がハウジングに揺動自在に支持され、かつ、吊り荷重を受けるためのころがり軸受けが締結部材とハウジングの間に配設されているので、吊り荷重の方向が変化する場合にも、リンク部材がハウジングに対して揺動し、かつ、締結部材がハウジングに対して円滑に回転するので、連れまわりトルクの発生が低く抑えられるため、吊持対象物に対する締結部材の固定状態が安定に維持される。また、締結部材がハウジングに対して回転する際に、大きな摩擦音（異音）は発生せず、作業時の騒音が低減され対環境性も良好となる。   In the swivel suspension according to the present invention, a link member for hooking a hook or the like is swingably supported by the housing, and a rolling bearing for receiving a suspension load is disposed between the fastening member and the housing. Since the link member swings with respect to the housing and the fastening member rotates smoothly with respect to the housing even when the direction of the suspension load changes, the generation of follow-up torque is low. Since it is suppressed, the fixed state of the fastening member with respect to the suspended object is stably maintained. Further, when the fastening member rotates with respect to the housing, no large frictional noise (abnormal noise) is generated, noise during operation is reduced, and environmental resistance is improved.

別の考案に係る旋回吊持具は、吊り荷重を受けるための間装部材をハードワッシャとブッシュで構成し、その当接面を、球面加工により上凸の球面状に形成するので、吊り荷重の方向が変化する場合にも、ハードワッシャとブッシュが柔軟に対応して連れまわりトルクの発生が低減され、吊持対象物に対する締結部材の固定状態を安定に維持することができる。   In the swivel suspension device according to another device, the interposition member for receiving the suspension load is composed of a hard washer and a bush, and the contact surface is formed into an upwardly convex spherical shape by spherical processing. Even when the direction changes, the hard washer and the bush flexibly correspond to each other, and the generation of the follow-up torque is reduced, so that the fixed state of the fastening member with respect to the suspended object can be stably maintained.

以下に、本考案の最良の実施の形態に係る旋回吊持具について図面を参照しつつ詳細に説明する。

[Embodiment 1]
FIG. 1 shows a configuration of a swivel holding tool, wherein reference numeral 1 denotes a fastening member such as a hexagon bolt fastened and fixed to a suspension object 20, and 2 rotatably supports the fastening member 1 in a retaining state. The housing 2 is formed in a substantially hollow cylindrical shape with an open bottom. Reference numeral 3 denotes a link member that is swingably supported by the housing 2, on which a hook or the like is hung. Reference numeral 4 denotes a thrust bearing as a rolling bearing for receiving a suspension load, and is disposed between the fastening member 1 and the housing 2. With such a configuration, after the fastening member is fixed to the suspension target object 20, a hook or the like can be hung on the link member 3 to lift the suspension target object 20.

全体の構成について詳細に説明すると、六角ボルト１は、ねじ部１ａと不完全ねじ部１ｂ及びヘッド部１ｃを有し、その不完全ねじ部１ｂにはアッパーブッシュ（本考案のブッシュ）５が嵌め込まれており、このアッパーブッシュ５は、六角ボルト１の不完全ねじ部１ｂに嵌め込まれる円筒状部５ｂの上端に六角ボルト１のヘッド部１ｃに当接するフランジ部５ａが形成され、そのフランジ部５ａの周縁部が下方に垂下されてスラストベアリング４の回転部を覆うカバー部５ｃが形成されている。このアッパーブッシュ５の下方にはロワーブッシュ１５が配設されている。なお、六角ボルト１は、吊持対象物２０に対してねじ込みによって固定されてもよく、ナットの締結によって固定されてもよい。   The overall configuration will be described in detail. The hexagon bolt 1 has a screw portion 1a, an incomplete screw portion 1b, and a head portion 1c, and an upper bush (bush of the present invention) 5 is fitted into the incomplete screw portion 1b. The upper bush 5 is formed with a flange portion 5a that is in contact with the head portion 1c of the hexagon bolt 1 at the upper end of the cylindrical portion 5b fitted into the incomplete thread portion 1b of the hexagon bolt 1, and the flange portion 5a. The cover part 5c which covers the rotating part of the thrust bearing 4 is formed by hanging the peripheral part of the thrust bearing 4 downward. A lower bush 15 is disposed below the upper bush 5. The hexagon bolt 1 may be fixed to the suspension target object 20 by screwing or may be fixed by fastening a nut.

ロワーブッシュ１５は、六角ボルト１のねじ部１ａと不完全ねじ部１ｂの下部にわたって被嵌される円筒状部１５ｂの下端に、吊持対象物２０に当接するフランジ部１５ａが形成されている。このフランジ部１５ａの内側の位置に対応する六角ボルト１のねじ部１ａには、脱落防止用の止め輪ｅを係止させるための切り溝が形成され、旋回吊持具を吊持対象物２０に取り付けない状態においても、リンク部材３を下方から支持するロワーブッシュ１５の脱落が防止され、旋回吊持具が一体化された状態に保持される。   In the lower bush 15, a flange portion 15 a that abuts the object to be suspended 20 is formed at the lower end of a cylindrical portion 15 b that is fitted over the lower portion of the screw portion 1 a and the incomplete screw portion 1 b of the hexagon bolt 1. The threaded portion 1a of the hexagonal bolt 1 corresponding to the inner position of the flange portion 15a is formed with a kerf for locking the retaining ring e for preventing the falling off, and the swivel suspension 20 Even in a state where the link member 3 is not attached, the lower bush 15 supporting the link member 3 from below is prevented from falling off, and the swivel suspension is held in an integrated state.

ハウジング２の中央には、アッパーブッシュ５の円筒状部５ｂを挿通させるための中央孔部２ａが形成され、ハウジング２の円筒状部の両側下部には、下向き開放状の凹部２ｃ，２ｃが形成され、該凹部２ｃ，２ｃには、リンク部材３の内側に折曲された脚部３b ，３b が回動自在に嵌め込まれ、かつ、その脚部３ｂの内側先端に上方に向けて突出するように形成された案内突起３ａが凹部２ｂの内側に抜け止め状態に嵌入されている。   A central hole 2a is formed in the center of the housing 2 to allow the cylindrical portion 5b of the upper bush 5 to pass therethrough, and downwardly open concave portions 2c and 2c are formed at the lower portions on both sides of the cylindrical portion of the housing 2. In the recesses 2c and 2c, leg portions 3b and 3b bent inside the link member 3 are rotatably fitted, and protrude upward from the inner end of the leg portion 3b. The guide protrusion 3a formed on the inside of the recess 2b is fitted into the recess 2b.

このような構成により、リンク部材３が、ハウジング２に対して１８０°回動自在（揺動自在）となるように支持される。また、下部開放の略中空円筒状に形成されるハウジング２に凹部２ｃ，２ｃを下向きの開口状に形成したので、旋回吊持具の組付時に、ロワーブッシュ１５を嵌め込む前に、リンク部材３を凹部２ｃ，２ｃに対して下方から嵌め込むことができるため、組み付け作業を良好なものとしている。   With such a configuration, the link member 3 is supported so as to be rotatable (swingable) by 180 ° with respect to the housing 2. Further, since the recesses 2c and 2c are formed in the downward opening in the housing 2 that is formed in a substantially hollow cylindrical shape that is open at the bottom, the link member is inserted before the lower bush 15 is fitted when the swivel suspension is assembled. 3 can be fitted into the recesses 2c, 2c from below, so that the assembling work is good.

ハウジング２の中央孔部２ａの上周縁には、スラストベアリング４の下部レース４ａを着座させるための着座部２ｂが形成されており、スラストベアリング４の上部レース４ｂは、アッパーブッシュ５の円筒状部５ｂとカバー部５ｃの間に形成されたリング状の凹部５ｄに嵌入される。このような構成により、下部レース４ａと上部レース４ｂの間に保持器４ｄによって遊嵌状態に保持される複数の鋼球４ｃによって吊り荷重が受けられ、下部レース４ａがハウジング２と共に、上部レース４ｂがアッパーブッシュ５と共に、それぞれ回動動作する。   A seat 2b for seating the lower race 4a of the thrust bearing 4 is formed on the upper peripheral edge of the central hole 2a of the housing 2, and the upper race 4b of the thrust bearing 4 is a cylindrical part of the upper bush 5. It is inserted into a ring-shaped recess 5d formed between 5b and the cover portion 5c. With such a configuration, a suspension load is received between the lower race 4a and the upper race 4b by the plurality of steel balls 4c held in a loosely fitted state by the retainer 4d, so that the lower race 4a together with the housing 2 has the upper race 4b. Rotate together with the upper bush 5.

以上のように構成される旋回吊持具は、吊り荷重が六角ボルト１とハウジング２の間に配設されたスラストベアリング４によって受けられるため、吊り荷重の方向が変化する場合にも、六角ボルト１がハウジング２に対して円滑に回転するので、連れまわりトルクの発生が低く抑えられ、吊持対象物２０に対する六角ボルト１の固定状態が安定に維持される。また、ころがり軸受け４では、面接触で荷重を受ける従来の旋回連結具のような大きな摩擦音（異音）は発生せず、作業時の騒音が低減され対環境性も良好となる。そして、スラストベアリング４の回転部分がカバー５ｃで覆われているため、回転部分への異物の侵入が阻止され、円滑な回転動作を維持することができ耐久性も向上する。   In the swivel holding device configured as described above, the suspension load is received by the thrust bearing 4 disposed between the hexagon bolt 1 and the housing 2, so that the hexagon bolt can be used even when the direction of the suspension load changes. Since 1 rotates smoothly with respect to the housing 2, the generation of accompanying torque is suppressed to a low level, and the fixed state of the hexagon bolt 1 with respect to the suspended object 20 is stably maintained. In addition, the rolling bearing 4 does not generate a large frictional noise (abnormal noise) unlike the conventional swivel coupler that receives a load due to surface contact, and noise during operation is reduced and environmental resistance is improved. And since the rotation part of the thrust bearing 4 is covered with the cover 5c, the penetration | invasion of the foreign material to a rotation part is blocked | prevented, smooth rotation operation | movement can be maintained and durability is also improved.

この旋回吊持具は、分解組み付け時の作業性がきわめて良好である。即ち、吊持対象物２０に締結されていない組み立てられた状態から分解する際には、止め輪ｅを外すことによって、六角ボルト１をアッパーブッシュ５及びロワーブッシュ１５から引き抜けば、ハウジング２、リンク部材３、スラストベアリング４、アッパーブッシュ５及びロワーブッシュ１５をそれぞれ個々に分離して取り外すことができる。一方、組み付ける際には、ハウジング２に挿入されたアッパーブッシュ５とハウジング２の間にスラストベアリング４を介在させた状態で六角ボルト１を嵌め込んだ後、ハウジング２に下方からリンク部材３を嵌め込み、次いで、ロワーブッシュ１５を六角ボルト１に嵌め込んで止め輪ｅを切り溝に係止させれば、組み付けが完了する。   This swivel holding tool has very good workability during disassembly and assembly. That is, when disassembling from an assembled state that is not fastened to the object 20 to be suspended, if the hexagon bolt 1 is pulled out from the upper bush 5 and the lower bush 15 by removing the retaining ring e, the housing 2, The link member 3, the thrust bearing 4, the upper bush 5 and the lower bush 15 can be individually separated and removed. On the other hand, when assembling, the hexagonal bolt 1 is fitted with the thrust bearing 4 interposed between the upper bush 5 inserted into the housing 2 and the housing 2, and then the link member 3 is fitted into the housing 2 from below. Then, when the lower bush 15 is fitted into the hexagon bolt 1 and the retaining ring e is locked in the cut groove, the assembly is completed.

A plurality of steel balls 6 are loosely fitted between the downward circumferential groove 5d formed in the above. Even in such a configuration, even when the direction of the suspension load changes, the hexagon bolt 1 rotates smoothly with respect to the housing 2. The fixed state of the bolt 1 is maintained stably. In addition, a large frictional noise (abnormal noise) unlike a conventional swivel connector that receives a load by surface contact does not occur, noise during operation is reduced, and environmental resistance is improved. And it can form compactly rather than the case where a thrust bearing is used as it is. In addition, the same code | symbol is attached | subjected about the same or equivalent member as previous embodiment, and the description is abbreviate | omitted. This also applies to the following embodiments.

図３に示す旋回吊持具では、ブッシュ５のフランジ部５ａの外周とハウジング２の上向きの円周溝２ｄの外側に形成される周状段部間に形成される隙間ｓを覆うための孔付きカバー（ワッシャ）７を六角ボルト１に嵌め込んでいる。このようにすれば、ころがり軸受け４の回転部分への異物の侵入が阻止されるため、六角ボルト１とハウジング２の間で円滑な回転動作を維持することができ、耐久性も向上する。   3, the hole for covering the clearance s formed between the outer periphery of the flange portion 5a of the bush 5 and the outer circumferential portion 2d formed on the outer side of the upward circumferential groove 2d of the housing 2. A cover (washer) 7 is fitted into the hexagon bolt 1. In this way, foreign matter can be prevented from entering the rotating portion of the rolling bearing 4, so that a smooth rotating operation can be maintained between the hexagon bolt 1 and the housing 2, and durability can be improved.

〔実施の形態３〕
図４に示す旋回吊持具では、ころがり軸受け４を、六角ボルト１に抜け止め状態に嵌め込まれるワッシャ８の下面と、六角ボルト１に抜け止め状態に嵌め込まれるブッシュ５の（ハウジング２に着座する）フランジ部５ａに形成される上向きの円周溝５ｅと、の間に複数の鋼球６を遊嵌させた構成としている。このような構成においても、吊り荷重の方向が変化しても、スラストベアリングと同様に六角ボルト１とハウジング２の間で円滑な回転動作を得ることができ、連れまわりトルクの発生が低く抑えられ、吊持対象物２０に対する六角ボルト１の固定状態は安定に維持される。また、面接触で荷重を受ける従来の旋回連結具のような大きな摩擦音（異音）は発生せず、吊り作業時の騒音が低減され対環境性も良好となる。そして、スラストベアリングをそのまま使用する場合よりもコンパクトに形成することができる。 [Embodiment 3]
In the swivel suspension shown in FIG. 4, the rolling bearing 4 is seated on the lower surface of a washer 8 fitted to the hexagonal bolt 1 in a retaining state and a bush 5 (fitted to the housing 2 in a retaining state on the hexagonal bolt 1. ) A plurality of steel balls 6 are loosely fitted between the upward circumferential groove 5e formed in the flange portion 5a. Even in such a configuration, even if the direction of the suspension load changes, a smooth rotation operation can be obtained between the hexagon bolt 1 and the housing 2 similarly to the thrust bearing, and the generation of the accompanying torque can be kept low. The fixed state of the hexagon bolt 1 with respect to the suspended object 20 is maintained stably. In addition, a large frictional noise (abnormal noise) unlike a conventional swivel connector that receives a load by surface contact does not occur, noise during suspension work is reduced, and environmental resistance is improved. And it can form compactly compared with the case where a thrust bearing is used as it is.

図５に示す旋回吊持具では、ワッシャ８の外周に、ころがり軸受け４の回転部分を覆うカバー部８ｃを形成している。このようにすれば、ころがり軸受け４の回転部分への異物の侵入が阻止されるため、六角ボルト１とハウジング２の間で円滑な回転動作を維持することができ、耐久性も向上する。   In the swivel suspension shown in FIG. 5, a cover portion 8 c that covers the rotating portion of the rolling bearing 4 is formed on the outer periphery of the washer 8. In this way, foreign matter can be prevented from entering the rotating portion of the rolling bearing 4, so that a smooth rotating operation can be maintained between the hexagon bolt 1 and the housing 2, and durability can be improved.

The contact surface of the hard washer 10 is formed with an upward convex spherical shape, and surface treatment such as chrome plating or zinc plating is performed, and the friction coefficient of the contact surface is set to 0.10 to 0.15. doing. Reference numeral 25 b denotes a cylindrical portion of the bush 25.

このような構成によれば、吊り荷重の方向が変化する場合にも、ハードワッシャ１０とブッシュ２５が柔軟に対応して両者間の摩擦力を少なくすることができ、連れまわりトルクの発生を低減して吊持対象物２０に対する締結部材１の固定状態を安定に維持することができる。なお、締結部材１は吊持対象物２０に対してねじ込みによって固定されてもよく、ナットの締結によって固定されてもよい。   According to such a configuration, even when the direction of the suspension load changes, the hard washer 10 and the bush 25 can flexibly cope with each other and reduce the frictional force between them, thereby reducing the generation of follow-up torque.
