　通常、ボルト等の螺旋状の雄ねじが少なくとも一部に形成された丸棒部材（以下、「丸棒部材」）にナットを螺合させる場合、丸棒部材の端部にナットの貫通孔を通し、丸棒部材に対してナットを回転させ、所望の位置までナットを移動させる必要がある。ナットを丸棒部材の全長に沿って移動させるには手間がかかるため、特許文献１（特公昭４７－２０５３０号公報）に記載の発明のように、一対の半割ナット部材と、一対の半割ナット部材を丸棒部材の直径方向外側に離すナット付勢部材と、一対の半割ナット部材を収納するカバー部材を備えた、早送りナットと呼ばれる製品が開発されている。 Normally, when a nut is screwed into a round bar member (hereinafter, "round bar member") in which a spiral male screw such as a bolt is formed at least in part, a through hole of the nut is passed through the end of the round bar member. , It is necessary to rotate the nut with respect to the round bar member and move the nut to a desired position. Since it takes time to move the nut along the entire length of the round bar member, as in the invention described in Patent Document 1 (Japanese Patent Publication No. 47-20530), a pair of half nut members and a pair of half nuts A product called a fast-forward nut has been developed, which includes a nut urging member that separates the split nut member outward in the radial direction of the round bar member and a cover member that houses a pair of half-split nut members.
　特許文献１に記載の早送りナットは、脚部３１が締付板７に到達するまでは、ナット付勢部材であるスプリング１４によって一対の半割ナット部材１２が引き離されている。そして、脚部３１が締付板７に到達すると、脚部３１により一対の半割ナット部材１２が押し上げられ、スプリング１４が圧縮され、丸棒部材に一対の半割ナット部材１２の雌ねじ部分が押し付けられ、丸棒部材の雄ねじと一対の半割ナット部材の雌ねじが螺合するようになっている。そのため、この早送りナットは、脚部３１が締付板７に到達するまでは、丸棒部材に沿って自在にスライド可能になっており、脚部３１が締付板７に到達すると、ナットとして機能するようになり、その後さらに早送りナットを回転させることで、締付板７を締め付けることができる。 In the fast-forward nut described in Patent Document 1, a pair of half-split nut members 12 are separated by a spring 14 which is a nut urging member until the leg portion 31 reaches the tightening plate 7. Then, when the leg portion 31 reaches the tightening plate 7, the pair of half-split nut members 12 are pushed up by the leg portion 31, the spring 14 is compressed, and the female screw portion of the pair of half-split nut members 12 is attached to the round bar member. It is pressed so that the male screw of the round bar member and the female screw of the pair of half nut members are screwed together. Therefore, this fast-forward nut can freely slide along the round bar member until the leg 31 reaches the veneer 7, and when the leg 31 reaches the veneer 7, it becomes a nut. The tightening plate 7 can be tightened by further rotating the fast-forward nut after it comes to function.

　しかしながら、特許文献１に記載の早送りナットの場合には、早送りナットが締結板に到達しない限りナットとして機能しないため、早送りナットを丸棒部材の任意の箇所で、ナットとしての機能を発揮させることができない。また、締結状態を解除するためには、脚部３１が締付板７から離れる位置まで早送りナットを回転させなければならない。さらに、ナット付勢部材であるスプリング１４は、一対の半割ナット部材１２の間に直接組み付けられるようになっているため、組み立て作業が難しい。 However, in the case of the fast-forward nut described in Patent Document 1, since the fast-forward nut does not function as a nut unless it reaches the fastening plate, the fast-forward nut should function as a nut at any position on the round bar member. I can't. Further, in order to release the tightened state, the fast-forward nut must be rotated to a position where the leg portion 31 is separated from the tightening plate 7. Further, since the spring 14 which is a nut urging member is directly assembled between the pair of half-split nut members 12, the assembling work is difficult.
　本発明の目的は、丸棒部材に沿ってスライド可能であり、丸棒部材の任意の箇所で丸棒部材の雄ねじと一対の半割ナット部材の雌ねじを螺合させることが可能な、すなわち、ナットとしての機能を発揮することが可能な早送りナットを提供することである。 An object of the present invention is that it is slidable along a round bar member, and a male screw of the round bar member and a female screw of a pair of half nut members can be screwed at any position of the round bar member, that is, The purpose is to provide a fast-forward nut that can function as a nut.
　また、本発明の他の目的は、該早送りナットを組み込んだ早送りナット組立品としての突っ張り棒やパンタグラフジャッキを提供することである。 Another object of the present invention is to provide a tension rod or a pantograph jack as a fast-forward nut assembly incorporating the fast-forward nut.
　本発明は、螺旋状の雄ねじが少なくとも一部に形成された丸棒部材を間に挟むように対向して配置され、雄ねじと螺合する雌ねじ部分を内周に備えた一対の半割ナット部材と、一対の半割ナット部材を丸棒部材から直径方向外側に離すように配置されたナット付勢部材と、一対の半割ナット部材及びナット付勢部材を収納する筒状のカバー部材を備え、カバー部材を一方向に動かす力により一対の半割ナット部材を径方向内側に向かって近付けて、ナット付勢部材を蓄勢しながら一対の半割ナット部材の雌ねじと丸棒部材の雄ねじ部分とを螺合させ、ナット付勢部材が発生する力を利用して一対の半割ナット部材の雌ねじと丸棒部材の雄ねじとの螺合の解除を行う早送りナットを対象にしている。 In the present invention, a pair of half-split nut members in which spiral male threads are arranged so as to sandwich a round bar member formed in at least a part thereof and have a female thread portion screwed with the male thread on the inner circumference. A nut urging member arranged so as to separate the pair of half-split nut members from the round bar member outward in the radial direction, and a tubular cover member for accommodating the pair of half-split nut members and the nut urging member. , The pair of half-split nut members are brought closer to each other in the radial direction by the force that moves the cover member in one direction, and while accumulating the nut urging member, the female thread of the pair of half-split nut members and the male thread portion of the round bar member The target is a fast-forward nut that unscrews the female screw of a pair of half-split nut members and the male screw of a round bar member by using the force generated by the nut urging member.
　本発明の早送りナットは、丸棒部材が貫通する貫通孔を備えた本体部と、貫通孔の径方向に対向するように本体部に形成されて、貫通孔と連通し且つ一対の半割ナット部材が径方向にスライドすることを許容するように一対の半割ナット部材を部分的に収納する一対の窓部を有し、カバー部材の内部にカバー部材に対して相対的に回転可能に配置された筒状部材を備え、カバー部材の内周面の輪郭形状は、一対の半割ナット部材が一対の窓部に収納された状態の筒状部材が収納される長軸と短軸とを有する楕円状形状を呈しており、一対の半割ナット部材の形状、筒状部材の形状、ナット付勢部材の取付位置及びカバー部材の内周面の楕円状形状は、カバー部材を筒状部材に対して相対的に一方向に回転させて、一対の半割ナット部材のスライド方向が楕円形状の長軸が延びる方向と一致しているときに、ナット付勢部材の放勢によって一対の半割ナット部材が丸棒部材から直径方向外側に離れて、一対の半割ナット部材の雌ねじと丸棒部材の雄ねじとの螺合が完全に解除された解除状態になり、解除状態から、カバー部材を筒状部材に対して相対的に一方向とは反対の方向に回転させて、一対の半割ナット部材のスライド方向が楕円形状の短軸が延びる方向と一致するまでに、カバー部材の内周面が一対の半割ナット部材をナット付勢部材の付勢力に抗して一対の半割ナット部材を径方向内側に向かって押して、一対の半割ナット部材の雌ねじと丸棒部材の雄ねじと螺合した螺合状態になるように定められている。 The fast-forward nut of the present invention is formed in the main body portion having a through hole through which the round bar member penetrates and the main body portion so as to face the radial direction of the through hole, and communicates with the through hole and is a pair of half nuts. It has a pair of windows that partially house a pair of half-nut members so that the members can slide in the radial direction, and is arranged inside the cover member so as to be relatively rotatable with respect to the cover member. The contour shape of the inner peripheral surface of the cover member is a long axis and a short axis in which a pair of half nut members are housed in a pair of windows. It has an elliptical shape, and the shape of the pair of half-split nut members, the shape of the tubular member, the mounting position of the nut urging member, and the elliptical shape of the inner peripheral surface of the cover member make the cover member a tubular member. When the sliding direction of the pair of half-split nut members coincides with the direction in which the long axis of the elliptical shape extends, the pair of half-split nut members are rotated relative to each other. The split nut member is separated from the round bar member outward in the radial direction, and the screw between the female screw of the pair of half nut members and the male screw of the round bar member is completely released, and the cover member is released from the released state. Is rotated in the direction opposite to one direction relative to the tubular member, until the sliding direction of the pair of half nut members coincides with the direction in which the elliptical minor axis extends. The peripheral surface pushes the pair of half-split nut members inward in the radial direction against the urging force of the nut urging member, and the female screw of the pair of half-split nut members and the male screw of the round bar member. It is stipulated that it will be in a screwed state.
　このように構成されているため、カバー部材を筒状部材に対して相対的に回転させるという簡単な操作だけで、螺合状態と解除状態を切り替えられ、丸棒部材に沿ってスライド可能であり、丸棒部材の任意の箇所で丸棒部材の雄ねじと一対の半割ナット部材の雌ねじを螺合させることが可能な早送りナットを得ることができる。 Since it is configured in this way, the screwed state and the released state can be switched by a simple operation of rotating the cover member relative to the tubular member, and the cover member can be slid along the round bar member. , A fast-forward nut capable of screwing a male screw of a round bar member and a female screw of a pair of half-split nut members at any position on the round bar member can be obtained.
　カバー部材の外周面の輪郭形状は、カバー部材の内周面に合わせて、楕円状形状に合わせたり、他の形状にすることも可能であるが、円筒状に形成されていることが好ましい。このようにすれば、早送りナットの使用者が早送りナットを保持しやすくなる。 The contour shape of the outer peripheral surface of the cover member can be adjusted to an elliptical shape or another shape according to the inner peripheral surface of the cover member, but it is preferably formed in a cylindrical shape. In this way, the user of the fast-forward nut can easily hold the fast-forward nut.
　カバー部材を筒状部材に対して一方向に相対的に回転させて、螺合状態から解除状態にする際に蓄勢され、カバー部材を一方向に相対的に回転させる力を解除すると放勢されるコイル状のトーションばねと、筒状部材に対して回転しないように配置されて、トーションばねをカバー部材に対して位置決めする位置決め部材をさらに備えており、トーションばねは、一端が位置決め部材に固定され、他端がカバー部材に固定されていることが好ましい。このようにすれば、回転力を加えたときだけ解除状態にすることができるため、螺合状態に戻すことを意識せずに早送りナットを用いることができる。 When the cover member is rotated relative to the tubular member in one direction and the screwed state is released, the energy is stored, and when the force that rotates the cover member relatively in one direction is released, the energy is released. It is further provided with a coiled torsion spring to be formed and a positioning member which is arranged so as not to rotate with respect to the tubular member and positions the torsion spring with respect to the cover member. One end of the torsion spring is a positioning member. It is preferably fixed and the other end is fixed to the cover member. In this way, since the release state can be set only when a rotational force is applied, the fast-forward nut can be used without being conscious of returning to the screwed state.
　カバー部材の外周面から径方向外側に延びる第１の指掛部と、位置決め部材に設けられた第２の指掛部とを備えており、第２の指掛部に指をかけた状態で、他の指を第１の指掛部にかけて、トーションばねの付勢力に抗して、第１の指掛部を第２の指掛部に引き寄せるように操作することで螺合状態から解除状態になるように構成されていてもよい。このようにすれば、第１の指掛部と第２の指掛部を摘まむ動作をすることで容易に解除状態にし、指を離すことで螺合状態にする早送りナットを得ることができる。 It is provided with a first finger hook portion extending radially outward from the outer peripheral surface of the cover member and a second finger hook portion provided on the positioning member, with a finger resting on the second finger hook portion. , The screwed state is released by putting another finger on the first finger hook and operating the first finger hook so as to pull the first finger hook toward the second finger hook against the urging force of the torsion spring. It may be configured to be. In this way, it is possible to obtain a fast-forward nut that can be easily released by pinching the first finger hook and the second finger hook, and screwed by releasing the finger. ..
　筒状部材は、径方向外側で且つ一対の窓部の間に位置する一対の仕切り壁を有しており、一対の仕切り壁と一対の半割ナット部材との間にそれぞれナット付勢部材を構成する複数の弾性部材が配置されていてもよい。この場合、一対の仕切り壁には、複数の弾性部材の一端を固定する有底の弾性部材固定孔が複数形成されており、一対の仕切り壁の１つの一方の面に形成された弾性部材固定孔と、該一方の面に対向する他方の面に形成された弾性部材固定孔は、貫通孔が延びる延伸方向にずれた位置に形成されていてもよい。このようにすることで、弾性部材固定孔の深さ寸法を最大で仕切り壁の厚みに近い寸法とすることができるため、弾性部材固定孔の深さ寸法を圧縮状態になった弾性部材の大部分が収まる深さにすることができるようになる。 The tubular member has a pair of partition walls located on the outer side in the radial direction and between the pair of windows, and a nut urging member is provided between the pair of partition walls and the pair of half-split nut members. A plurality of constituent elastic members may be arranged. In this case, the pair of partition walls is formed with a plurality of bottomed elastic member fixing holes for fixing one ends of the plurality of elastic members, and the elastic member fixing holes formed on one surface of the pair of partition walls. The hole and the elastic member fixing hole formed on the other surface facing the one surface may be formed at a position deviated in the extending direction in which the through hole extends. By doing so, the depth dimension of the elastic member fixing hole can be set to a dimension close to the thickness of the partition wall at the maximum, so that the depth dimension of the elastic member fixing hole is large in the compressed state. You will be able to make the part fit.
　一対の半割ナット部材のそれぞれの外周面は、解除状態から螺合状態にする際にカバー部材の内周面が接触する面が曲面になっていることが好ましい。これによりカバー部材がスムーズに回転する。この場合、さらに、一対の仕切り壁のそれぞれは、解除状態から螺合状態にする際にカバー部材の内周面が接触した半割ナット部材の回転を留める、仕切り壁の径方向外側端部壁から周方向に延びる延長壁部を有しており、一対の半割ナット部材のそれぞれには、延長壁部の内壁面に沿う平坦面が形成されていることが好ましい。これにより、半割ナット部材が延長壁部によってガイドされてスライド可能になる。 It is preferable that each outer peripheral surface of the pair of half-split nut members has a curved surface on which the inner peripheral surface of the cover member comes into contact when changing from the released state to the screwed state. As a result, the cover member rotates smoothly. In this case, each of the pair of partition walls further holds the rotation of the half-split nut member that the inner peripheral surface of the cover member comes into contact with when changing from the released state to the screwed state, and the radial outer end wall of the partition wall. It is preferable that each of the pair of half-split nut members has an extension wall portion extending in the circumferential direction from the extension wall portion, and a flat surface along the inner wall surface of the extension wall portion is formed. As a result, the half-split nut member is guided by the extension wall portion and can slide.
　一対の半割ナット部材は、同形状の半割ナット部材からなり、一対の窓部の一方は、他方に対して、貫通孔が延びる方向に、一対の半割ナット部材の雌ねじ部分の半ピッチ分ずれた位置に形成されていてもよい。このようにすることで、同一形状・同一寸法の２つの半割ナット部材を一対の半割ナット部材として用いることができるようになる。 The pair of half-split nut members are made of half-split nut members of the same shape, and one of the pair of window portions has a half pitch of the female thread portion of the pair of half-split nut members in the direction in which the through hole extends with respect to the other. It may be formed at a separated position. By doing so, it becomes possible to use two half-split nut members having the same shape and the same size as a pair of half-split nut members.
　カバー部材には、径方向外側に向かって延びる把持レバーが設けられていてもよい。このようにすれば、把持レバーに届く離れた位置から早送りナットを操作することができる。 The cover member may be provided with a gripping lever extending outward in the radial direction. In this way, the fast-forward nut can be operated from a position far away from the grip lever.
　本発明の早送りナットは、これを組み込んだ組立品に用いることも可能である。例えば、上述した早送りナットを突っ張り棒に組み込むことができる。早送りナットを組み込んだ突っ張り棒は、丸棒部材の端部に、２つの対向する壁面のうち一方の壁面と当接する第１の当接部を有し、２つの対向する壁面のうち他方の壁面と当接する第２の当接部を端部に有し、他方の端部に丸棒部材が挿通される開口部が形成された筒状体を備えている。そして、筒状体の他方の端部には、上述した早送りナットが、本体部の貫通孔が開口部と整合するようにカバー部材が配置された状態で固定されている。 The fast-forward nut of the present invention can also be used in an assembly incorporating the fast-forward nut. For example, the fast-forward nut described above can be incorporated into the tension rod. The tension rod incorporating the fast-forward nut has a first contact portion that abuts on one of the two opposing wall surfaces at the end of the round bar member, and the other wall surface of the two opposing wall surfaces. It is provided with a tubular body having a second contact portion at the end thereof, and an opening through which a round bar member is inserted is formed at the other end portion. The fast-forward nut described above is fixed to the other end of the tubular body in a state where the cover member is arranged so that the through hole of the main body is aligned with the opening.
　このように構成された突っ張り棒は、早送りナットを解除状態にして、丸棒部材を筒状体内に押し込む、または、筒状体から引っ張りだして突っ張り棒の長さの粗調整を行うことができる。そして、粗調整後、早送りナットを螺合状態にして、丸棒部材を筒状体に対して回転させて突っ張り棒の長さの微調整を行うことができる。 With the tension rod configured in this way, the fast-forward nut can be released and the round bar member can be pushed into the tubular body or pulled out from the tubular body to roughly adjust the length of the tension rod. .. Then, after the rough adjustment, the fast-forward nut can be screwed and the round bar member can be rotated with respect to the tubular body to finely adjust the length of the tension rod.
　また、本発明の早送りナットは、例えば、パンタグラフジャッキに組み込むことができる。早送りナットを組み込んだパンタグラフジャッキは、基台を介して連結された第１の一対のリンクアームからなる下部リンク機構と、受け座を介して連結された第２の一対のリンクアームからなる上部リンク機構と、下部リンク機構と上部リンク機構とをパンタグラフ状に連結する、保持用連結部及び作動用連結部とを備え、保持用連結部に一端を回動自在に且つ軸方向には移動しないよう保持させた丸棒部材が作動用連結部に螺合され、丸棒部材の保持用連結部より外側へ突出した突出部に取り付けられた回転操作部により丸棒部材が回転させられるように、保持用連結部と作動用連結部との間隔が拡縮可能に構成され、作動用連結部が、上述した早送りナットを含んでいる。そして、丸棒部材が、早送りナットの一対の半割ナット部材によって作動用連結部に螺合している。 Further, the fast-forward nut of the present invention can be incorporated into, for example, a pantograph jack. The pantograph jack incorporating the fast-forward nut has a lower link mechanism consisting of a first pair of link arms connected via a base and an upper link consisting of a second pair of link arms connected via a receiving seat. It is provided with a holding connecting portion and an operating connecting portion that connect the mechanism, the lower link mechanism and the upper link mechanism in a pantograph shape, and one end of the holding connecting portion is rotatable and does not move in the axial direction. The held round bar member is screwed into the operating connecting portion, and is held so that the round bar member is rotated by the rotation operating portion attached to the protruding portion protruding outward from the holding connecting portion of the round bar member. The distance between the working connecting part and the working connecting part is configured to be expandable and contractible, and the working connecting part includes the above-mentioned fast-forward nut. Then, the round bar member is screwed into the operating connecting portion by a pair of half-split nut members of the fast-forward nut.
　このように早送りナットを組み込んだパンタグラフジャッキは、早送りナットを解除状態にすると、回転操作部を回転させることなく作動用連結部を丸棒部材の軸方向に移動させることができるようになり、保持用連結部と作動用連結部との間隔が拡縮可能になる。すなわち、この状態で基台と受け座の間の距離の粗調整を行うことができる。そして、粗調整後、早送りナットを螺合状態にすることで、回転操作部を回転させて基台と受け座の間の距離の微調整を行うことができる。 In the pantograph jack incorporating the fast-forward nut in this way, when the fast-forward nut is released, the operating connecting part can be moved in the axial direction of the round bar member without rotating the rotation operation part, and is held. The distance between the working connecting part and the working connecting part can be expanded or contracted. That is, in this state, the distance between the base and the pedestal can be roughly adjusted. Then, after the rough adjustment, the fast-forward nut is brought into a screwed state, so that the rotation operation unit can be rotated to finely adjust the distance between the base and the receiving seat.

The direction (third direction D3) is defined as shown in FIG. In other figures, the same direction as that used in the explanation of FIG. 2 is used.
　＜構成部材＞
　早送りナット１は、主に、筒状部材３と、一対の半割ナット部材５，７と、ナット付勢部材を構成する弾性部材９Ａ乃至９Ｄと、カバー部材１１と、トーションばね１３と、位置決め部材１５とを備えている。 <Components>
The fast-forward nut 1 is mainly positioned with a tubular member 3, a pair of half- split nut members 5, 7, elastic members 9A to 9D constituting the nut urging member, a cover member 11, and a torsion spring 13. It includes a member 15.
　［筒状部材、半割ナット部材、弾性部材］
　筒状部材３は、丸棒部材ＣＲが貫通する貫通孔２３を備えた本体部１７と、貫通孔２３の径方向に対向するように本体部１７に形成されて、貫通孔２３と連通し且つ一対の半割ナット部材５，７が径方向にスライドすることを許容するように一対の半割ナット部材５，７を部分的に収納する一対の窓部１９，２１を有し、カバー部材１１の内部にカバー部材１１に対して相対的に回転可能に配置されている。図４に示すように、筒状部材３の周囲には、カバー部材１１が所定の角度範囲を回転するように、回り止め４，４が形成されている。 [Cylindrical member, half nut member, elastic member]
The tubular member 3 is formed in the main body 17 having a through hole 23 through which the round bar member CR penetrates, and in the main body 17 so as to face the through hole 23 in the radial direction, and communicates with the through hole 23. The cover member 11 has a pair of window portions 19, 21 for partially accommodating the pair of half- split nut members 5, 7 so as to allow the pair of half- split nut members 5, 7 to slide in the radial direction.
