Description
本発明は、例えば、壁や天井などの構造体に吊設される空調機等の機器類や配管ダクト類に対する振れ止め措置として、振れ止め措置対象の複数の吊りボルトにわたって振れ止めボルトを傾斜姿勢で固定連結するなど、二本の棒状体を交差姿勢で係合連結する場合に用いられる棒状体用交差連結具に関する。 The present invention, for example, as an anti-vibration measure for devices such as air conditioners suspended from structures such as walls and ceilings and piping ducts, the anti-vibration bolt is inclined over a plurality of suspension bolts to be anti-vibration measures. It is related with the cross-connecting tool for rod-shaped bodies used when two rod-shaped bodies are engaged and coupled in a crossing posture, such as fixedly coupled with each other.
従来の棒状体用交差連結具では、両端部を互いに近づける側に弾性変形操作可能な形態に屈曲形成されている長尺な連結部材の内面側の中央部に、コの字状に屈曲形成された短尺な連結部材が、屈曲方向を同じ側に向けた状態で相対回転自在に枢支連結されている。
前記長尺連結部材は、枢支連結孔を備えた中央板部と、これに対して交差する傾斜姿勢で該中央板部の両端から同一側に延出される傾斜板部と、該両傾斜板部の先端側に延出される操作板部を備えて構成され、前記両傾斜板部には、一方の棒状体に対してそれに交差する方向の同一側から係入自在な開口を備えた第1係合部が形成されている。
前記短尺連結部材の両端には、他方の棒状体に対してそれに交差する方向の同一側から係入自在なV字状の第2係合部が形成されている(特許文献1,2参照)。
In the conventional cross-connector for rod-shaped bodies, the both end portions are bent and formed in a U-shape at the center on the inner surface side of a long connecting member that is bent into a shape that can be elastically deformed to the side where both ends approach each other. The short connecting members are pivotally connected so as to be relatively rotatable with the bending direction directed to the same side.
The long connecting member includes a central plate portion provided with a pivot connecting hole, an inclined plate portion extending from both ends of the central plate portion in an inclined posture intersecting with the central plate portion, and both the inclined plates. The first plate is provided with an opening that can be engaged from the same side in the direction intersecting the one rod-shaped body. An engaging portion is formed.
At both ends of the short connecting member, V-shaped second engaging portions that can be engaged from the same side in the direction intersecting the other rod-shaped body are formed (see Patent Documents 1 and 2). .
従来の棒状体用交差連結具では、前記二本の棒状体を交差姿勢で係合連結する場合、前記短尺連結部材の両端に形成されているV字状の第2係合部を、手前側に位置する棒状体に係合し、その状態を維持したまま、前記長尺連結部材の両操作板部を互いに近づける側に弾性変形操作し、該長尺連結部材の両傾斜板部に形成されている第1係合部を、後方側に位置する棒状体に対してそれに交差する方向の同一側から係入させたのち、前記両操作板部に加えられていた近接操作力を解除し、長尺連結部材の弾性復元力で両第1係合部を棒状体に係合させている。 In the conventional cross connecting tool for rod-like bodies, when the two rod-like bodies are engaged and connected in a crossing posture, the V-shaped second engaging portions formed at both ends of the short connecting member are connected to the front side. The long connecting member is formed on both slanted plate parts by elastically deforming the two connecting plate parts of the long connecting member closer to each other while maintaining the state. The first engaging portion is engaged with the rod-like body located on the rear side from the same side in the direction intersecting it, and then the proximity operation force applied to both the operation plate portions is released, Both first engaging portions are engaged with the rod-like body by the elastic restoring force of the long connecting member.
しかし、一方の棒状体に対する長尺連結部材の係合位置又は他方の棒状体に対する短尺連結部材の係合位置を変更する必要が生じたとき、長尺連結部材の両操作板部を互いに近づける側に弾性変形操作して、一方の棒状体と両第1係合部の係合を解除すると、短尺連結部材の両第2係合部と他方の棒状体との係合も同時に解除される。 However, when it becomes necessary to change the engagement position of the long coupling member with respect to one rod-shaped body or the engagement position of the short coupling member with respect to the other rod-shaped body, the side where the two operation plate portions of the long coupling member are brought closer to each other When the engagement between one rod-shaped body and both first engaging portions is released by elastic deformation operation, the engagement between both second engaging portions of the short connecting member and the other rod-shaped body is also released simultaneously.
そのため、例えば、短尺連結部材が係合されている他方の棒状体に対して、長尺連結部材の両第1係合部が係合されていた一方の棒状体の位置を変更する必要が生じた場合には、短尺連結部材の第2係合部を他方の棒状体に押し付けて係合状態を維持し、且つ、長尺連結部材の両操作板部を互いに近づける側に弾性変形操作したまま、一方の棒状体を他方の棒状体に対して位置変更分だけ移動操作する必要がある。 Therefore, for example, it is necessary to change the position of one rod-like body with which both first engaging portions of the long coupling member are engaged with the other rod-like body with which the short connecting member is engaged. In this case, the second engaging portion of the short connecting member is pressed against the other rod-shaped body to maintain the engaging state, and the two connecting plate portions of the long connecting member are elastically deformed so as to approach each other. It is necessary to move one rod-like body by the amount corresponding to the position change with respect to the other rod-like body.
また、長尺連結部材の両第1係合部が係合されていた一方の棒状体に対して、短尺連結部材が係合されている他方の棒状体の係合位置を変更する必要が生じた場合には、長尺連結部材の両操作板部を互いに近づける側に弾性変形操作して、短尺連結部材の第2係合部を他方の棒状体から遊離した係合解除状態に維持し、その状態で一方の棒状体に対して他方の棒状体を位置変更分だけ移動操作する必要がある。 Moreover, it is necessary to change the engagement position of the other rod-shaped body with which the short coupling member is engaged with respect to the one rod-shaped body with which both the first engaging portions of the long coupling member are engaged. In the case where the two connecting plates of the long connecting member are elastically deformed to approach each other, the second engaging portion of the short connecting member is maintained in the disengaged state released from the other rod-shaped body, In this state, it is necessary to move and move the other rod-shaped body by the amount corresponding to the position change.
それ故に、上述のいずれの場合でも、長尺連結部材の両第1係合部と短尺連結部材の第2係合部とが同時的に作用する可能性があり、且つ、両棒状体同士が接触して干渉することがあるため、両棒状体の位置変更操作が煩雑化し、一人作業では手間取り易く、作業性の低下を招来していた。 Therefore, in any of the cases described above, both the first engaging portions of the long connecting member and the second engaging portion of the short connecting member may act simultaneously, and both rod-shaped bodies are connected to each other. Since they may come into contact with each other and interfere with each other, the operation of changing the positions of both rod-shaped bodies is complicated, and it is easy to take time and effort by one person, resulting in a decrease in workability.
本発明は、上述の実状に鑑みて為されたものであって、その主たる課題は、交差姿勢で係合連結される両棒状体の位置変更操作を片手で能率良く容易に行うことのできる棒状体用交差連結具を提供する点にある。 The present invention has been made in view of the above-mentioned actual situation, and its main problem is that the rod-shaped body can be easily and efficiently operated with one hand to change the position of both rod-shaped bodies engaged and connected in an intersecting posture. It is in providing a cross connector for the body.
本発明による第1の特徴構成は、二本の棒状体を交差姿勢で係合連結する棒状体用交差連結具であって、
一方の棒状体の二箇所に対して弾性復元力で係合保持可能な係合部を備え、且つ前記両係合部を互いに近づける側への弾性変形操作で該係合部が係合解除される形態に屈曲形成されている一対の連結部材が、互いに逆向き姿勢となる背中合わせで相対回転自在に枢支連結され、前記各連結部材が、枢支連結孔を備えた中央板部と、これに対して交差する傾斜姿勢で該中央板部の両端から同一側に延出される傾斜板部と、該両傾斜板部の先端側に延出される操作板部を備えた帯板状のバネ板部材から構成されている点にある。
A first characteristic configuration according to the present invention is a cross-connecting tool for a rod-like body that engages and connects two rod-like bodies in a crossing posture,
An engagement portion that can be engaged and held with elastic restoring force at two locations of one rod-like body is provided, and the engagement portion is disengaged by an elastic deformation operation to bring both the engagement portions closer to each other. A pair of connecting members that are bent in such a manner that they are pivotally connected to each other so as to be rotatable relative to each other in a back-to-back posture, and each of the connecting members includes a central plate portion having a pivot connecting hole, A strip-shaped spring plate having an inclined plate portion extending from the both ends of the central plate portion to the same side in an inclined posture intersecting with the operation plate portion and an operation plate portion extending to the distal end side of the both inclined plate portions It is in the point comprised from the member .
上記特徴構成によれば、二本の棒状体を交差姿勢で係合連結する場合、枢支連結されている一対の連結部材の一方をそれの両係合部が近接する側に弾性変形操作し、この連結部材における両係合部間の枢支連結部位を両棒状体の交差重合部位間に位置させた状態で前記両係合部を一方の棒状体に係合させたのち、該連結部材に加えられていた近接操作力を解除し、一方の連結部材の弾性復元力で両係合部を一方の棒状体に係合保持させることができる。 According to the above characteristic configuration, when two rod-like bodies are engaged and connected in a crossing posture, one of the pair of connecting members that are pivotally connected is elastically deformed to the side where both engaging portions thereof are close to each other. Then, after engaging the both engaging portions with one rod-shaped body in a state where the pivotally coupled portion between the both engaging portions of the connecting member is positioned between the cross-overlapping sites of both rod-shaped bodies, the connecting member It is possible to release the proximity operating force applied to the two and engage and hold the two engaging portions on one rod-like body by the elastic restoring force of one connecting member.
他方の連結部材は、一方の棒状体に係合保持された一方の連結部材に対して背中合わせで相対回転自在に枢支連結されているため、一方の棒状体及び一方の連結部材に対する特別な操作が不要で、他方の連結部材をそれの両係合部が近接する側に弾性変形操作して、この連結部材の両係合部を他方の棒状体に係合したのち、該連結部材に加えられていた近接操作力を解除するだけで、他方の連結部材の弾性復元力で両係合部を他方の棒状体に係合保持させることができる。 Since the other connecting member is pivotally connected back to back relative to one connecting member engaged and held by one rod-like body, a special operation for one rod-like body and one connecting member is performed. Is not necessary, and the other connecting member is elastically deformed to the side where both engaging portions thereof are close to each other, and both engaging portions of this connecting member are engaged with the other rod-shaped body, and then added to the connecting member. It is possible to engage and hold the two engaging portions with the other rod-shaped body by the elastic restoring force of the other connecting member simply by releasing the approaching force that has been applied.
また、一方の連結部材が係合保持されている一方の棒状体に対して、他方の連結部材が係合保持されている他方の棒状体の位置を変更する必要が生じた場合でも、その位置変更対象である他方の連結部材をそれの両係合部が近接する側に弾性変形操作して、他方の棒状体との係合位置を変更操作するだけで済む。 Even if it becomes necessary to change the position of the other rod-shaped body on which one of the connecting members is engaged and held, the position of the other rod-shaped body on which the other connecting member is engaged and held. It is only necessary to elastically deform the other connecting member to be changed toward the side where both engaging portions thereof are close to each other and change the engagement position with the other rod-shaped body.
従って、前記両棒状体の交差重合部位間を、背中合わせで相対回転自在に枢支連結された両連結部材の枢支連結部位によって物理的に分断することにより、従来装置のように、長尺連結部材の両第1係合部と短尺連結部材の第2係合部とが同時的に作用する可能性を排除することができると同時に、両棒状体同士が接触して干渉することを回避することができるため、両棒状体の位置変更操作が簡素になり、交差姿勢で係合連結される両棒状体の位置変更操作を片手で能率良く容易に行うことができる。 Accordingly, the cross-overlapping sites of the rod-like bodies are physically separated by the pivotal coupling sites of the two coupling members pivotally coupled to each other so as to be rotatable relative to each other. It is possible to eliminate the possibility that both the first engaging portions of the member and the second engaging portion of the short connecting member act simultaneously, and at the same time, avoid contact and interference between the rod-shaped bodies. Therefore, the position changing operation of both rod-like bodies is simplified, and the position changing operation of both rod-like bodies engaged and connected in the crossing posture can be easily and efficiently performed with one hand.
しかも、前記両連結部材を背中合わせで相対回転自在に枢支連結しながらも、前記両棒状体に係合保持された状態では、各連結部材が両棒状体の交差重合部位間を装着起点として各棒状体の外周面に沿って装着されるから、両連結部材の端部の外方への張り出し量が少なくなり、他物との引っ掛かりを抑制することができる。 In addition, while both the connecting members are pivotally connected to each other so as to be rotatable relative to each other, the connecting members are engaged with and held by the both rod-shaped bodies, and each connecting member has a crossing site between the both rod-shaped bodies as a mounting starting point. Since it is mounted along the outer peripheral surface of the rod-shaped body, the amount of outward protrusion of the end portions of both connecting members is reduced, and the catching with other objects can be suppressed.
本発明による第2の特徴構成は、二本の棒状体を交差姿勢で係合連結する棒状体用交差連結具であって、
両端部を互いに近づける側に弾性変形操作可能な形態に屈曲形成されている一対の連結部材が、互いに逆向き姿勢となる背中合わせで相対回転自在に枢支連結されているとともに、前記各連結部材の両側部には、前記棒状体に対して交差方向から係入自在な開口を備えた凹状の係合部が形成され、前記連結部材の両端部を互いに近づける側への弾性変形操作で前記両係合部が棒状体に対して係脱自在に構成され、前記連結部材の弾性復元力で前記両係合部が棒状体に対して係合可能に構成され、前記各連結部材が、枢支連結孔を備えた中央板部と、これに対して交差する傾斜姿勢で該中央板部の両端から同一側に延出される傾斜板部と、該両傾斜板部の先端側に延出される操作板部を備えた帯板状のバネ板部材から構成されている点にある。
A second characteristic configuration according to the present invention is a rod-shaped body cross-connecting device that engages and connects two rod-shaped bodies in a crossing posture,
A pair of connecting members that are bent in a form that can be elastically deformed to the side where both ends are brought close to each other are pivotally connected back-to-back in a reverse orientation to each other, and On both sides, a concave engagement portion having an opening that can be engaged with the rod-like body from the crossing direction is formed, and the both engagement portions are elastically deformed to bring both ends of the connecting member closer to each other. The joint portion is configured to be detachable with respect to the rod-shaped body, the both engaging portions are configured to be engageable with the rod-shaped body by the elastic restoring force of the coupling member, and each of the coupling members is pivotally coupled. A central plate portion provided with holes, an inclined plate portion extending to the same side from both ends of the central plate portion in an inclined posture intersecting with the central plate portion, and an operation plate extending to the front end side of the both inclined plate portions It is in the point comprised from the strip-shaped spring board member provided with the part .
上記特徴構成によれば、二本の棒状体を交差姿勢で係合連結する場合、枢支連結されている一対の連結部材の一方をそれの両係合部が近接する側に弾性変形操作し、この連結部材における両係合部間の枢支連結部位を両棒状体の交差重合部位間に位置させた状態で前記両係合部を一方の棒状体に対して交差方向から係合させたのち、該連結部材に加えられていた近接操作力を解除し、一方の連結部材の弾性復元力で両係合部を一方の棒状体に係合保持させることができる。 According to the above characteristic configuration, when two rod-like bodies are engaged and connected in a crossing posture, one of the pair of connecting members that are pivotally connected is elastically deformed to the side where both engaging portions thereof are close to each other. The both engaging portions are engaged with one rod-like body from the crossing direction in a state in which the pivot connection portion between the both engaging portions of the connecting member is located between the cross-overlapping sites of both rod-like bodies. After that, the proximity operating force applied to the connecting member can be released, and both engaging portions can be engaged and held on one rod-like body by the elastic restoring force of one connecting member.
他方の連結部材は、一方の棒状体に係合保持された一方の連結部材に対して背中合わせで相対回転自在に枢支連結されているため、一方の棒状体及び一方の連結部材に対する特別な操作が不要で、他方の連結部材をそれの両係合部が近接する側に弾性変形操作して、この連結部材の両係合部を他方の棒状体に対して交差方向から係合させたのち、該連結部材に加えられていた近接操作力を解除するだけで、他方の連結部材の弾性復元力で両係合部を他方の棒状体に係合保持させることができる。 Since the other connecting member is pivotally connected back to back relative to one connecting member engaged and held by one rod-like body, a special operation for one rod-like body and one connecting member is performed. After the other connecting member is elastically deformed to the side where both engaging portions are close to each other, the engaging portions of the connecting member are engaged with the other rod-shaped body from the crossing direction. By simply releasing the proximity operation force applied to the connecting member, the two engaging members can be engaged and held with the other rod-like body by the elastic restoring force of the other connecting member.
また、一方の連結部材が係合保持されている一方の棒状体に対して、他方の連結部材が係合保持されている他方の棒状体の位置を変更する必要が生じた場合でも、その位置変更対象である他方の連結部材をそれの両係合部が近接する側に弾性変形操作して、他方の棒状体との係合位置を変更操作するだけで済む。 Even if it becomes necessary to change the position of the other rod-shaped body on which one of the connecting members is engaged and held, the position of the other rod-shaped body on which the other connecting member is engaged and held. It is only necessary to elastically deform the other connecting member to be changed toward the side where both engaging portions thereof are close to each other and change the engagement position with the other rod-shaped body.
従って、前記両棒状体の交差重合部位間を、背中合わせで相対回転自在に枢支連結された両連結部材の枢支連結部位によって物理的に分断することにより、従来装置のように、長尺連結部材の両第1係合部と短尺連結部材の第2係合部とが同時的に作用する可能性を排除することができると同時に、両棒状体同士が接触して干渉することを回避することができるため、両棒状体の位置変更操作が簡素になり、交差姿勢で係合連結される両棒状体の位置変更操作を片手で能率良く容易に行うことができる。 Accordingly, the cross-overlapping sites of the rod-like bodies are physically separated by the pivotal coupling sites of the two coupling members pivotally coupled to each other so as to be rotatable relative to each other. It is possible to eliminate the possibility that both the first engaging portions of the member and the second engaging portion of the short connecting member act simultaneously, and at the same time, avoid contact and interference between the rod-shaped bodies. Therefore, the position changing operation of both rod-like bodies is simplified, and the position changing operation of both rod-like bodies engaged and connected in the crossing posture can be easily and efficiently performed with one hand.
しかも、前記両連結部材を背中合わせで相対回転自在に枢支連結しながらも、前記両棒状体に係合保持された状態では、各連結部材が両棒状体の交差重合部位間を装着起点として各棒状体の外周面に沿って装着されるから、両連結部材の端部の外方への張り出し量が少なくなり、他物との引っ掛かりを抑制することができる。 In addition, while both the connecting members are pivotally connected to each other so as to be rotatable relative to each other, the connecting members are engaged with and held by the both rod-shaped bodies, and each connecting member has a crossing site between the both rod-shaped bodies as a mounting starting point. Since it is mounted along the outer peripheral surface of the rod-shaped body, the amount of outward protrusion of the end portions of both connecting members is reduced, and the catching with other objects can be suppressed.

Even if one connecting member can be easily engaged and disengaged from the body and is in a semi-constrained state where one connecting member is engaged and held by one rod-like body, the other connecting member can be connected using the relative rotation function of both connecting members. Both engaging portions of the member can be easily engaged and held with the other rod-shaped body.
本発明による第4の特徴構成は、前記棒状体における少なくとも連結部材との係合箇所には雄ネジ部が形成されているとともに、前記係合部には、前記棒状体の雄ネジ部の谷部に対して係合可能な係合爪が形成されている点にある。 According to a fourth characteristic configuration of the present invention, a male screw portion is formed at least at a position where the rod-shaped body is engaged with the connecting member, and the engagement portion includes a valley of the male screw portion of the rod-shaped body. An engaging claw that can be engaged with the portion is formed.
