Description

本発明は、互いに交差する２本の棒状体どうしを連結する交差連結具に関する。   The present invention relates to a cross connector that connects two rod-shaped bodies that cross each other.

例えば空調機器の室内機や、照明機器、ケーブルラック等の吊設機器は、例えばその四隅にて、棒状体を用いて天井スラブ等の構造体から吊設される場合がある。このような場合において、地震等に起因する吊設機器の揺れ動きを抑制するため、垂設される一対の棒状体に対して交差姿勢で別の棒状体を配設し、これらを相互に連結して補強する場合がある。また、そのような補強用の棒状体を２本用い、これらを交差姿勢で配設しつつ相互に連結してさらに補強する場合がある。これらの場合、互いに交差する２本の棒状体どうしを連結する交差連結具が用いられる。   For example, an indoor unit of an air conditioner, a lighting device, a cable rack, and other suspended devices may be suspended from a structure such as a ceiling slab using bar-shaped bodies at four corners, for example. In such a case, in order to suppress the swinging movement of the suspended equipment caused by an earthquake or the like, another rod-shaped body is arranged in a crossing posture with respect to the pair of rod-shaped bodies suspended, and these are connected to each other. May be reinforced. Further, there are cases where two such reinforcing rod-like bodies are used and are further reinforced by being connected to each other while being arranged in a crossing posture. In these cases, a cross connector that connects two rod-shaped bodies that cross each other is used.

このような交差連結具として、例えば特開２０１４−２１４７８８号公報（特許文献１）に記載されたものが知られている。特許文献１の交差部支持金具１０は、振止部材５０が配設される溝部２１を有する第１円盤部材２０と、振止部材５１が配設される溝部３１を有する第２円盤部材３０とを備え、両円盤部材２０，３０が２組のボルト・ナットで締結される。第２円盤部材３０にはボルト４０，４１が挿通される円弧状の穿孔３２，３３が形成されており、第１円盤部材２０と第２円盤部材３０とが相対回転可能であることにより、振止部材５０と振止部材５１との交差角度を変更することが可能となっている。   As such a cross-connecting tool, for example, one described in JP 2014-214788 A (Patent Document 1) is known. The cross-section support metal fitting 10 of Patent Document 1 includes a first disk member 20 having a groove portion 21 in which a bracing member 50 is disposed, and a second disk member 30 having a groove portion 31 in which a bracing member 51 is disposed. The disk members 20 and 30 are fastened with two sets of bolts and nuts. The second disk member 30 is formed with arc-shaped perforations 32 and 33 through which the bolts 40 and 41 are inserted, and the first disk member 20 and the second disk member 30 can rotate relative to each other. It is possible to change the crossing angle between the stop member 50 and the anti-vibration member 51.

しかし、上記の構成では、振止部材５０，５１に対する交差部支持金具１０の取付時に、互いに独立した部材である両円盤部材２０，３０の両方が脱落しないように押さえながら２組のボルト・ナットで締結する必要があり、取付作業に手間取る場合がある。また、例えば振動等によって振止部材５０，５１の交差角度が変動し、両円盤部材２０，３０に回転方向の力が作用した場合には、締結用のボルト・ナットに緩みが生じ、連結固定力が低下する可能性がある。   However, in the above-described configuration, two sets of bolts and nuts are held while holding both the disk members 20 and 30 so as not to drop off at the time of attachment of the crossing support bracket 10 to the bracing members 50 and 51. It may be necessary to fasten with, and it may take time to install. Further, for example, when the crossing angle of the bracing members 50 and 51 fluctuates due to vibration or the like and a force in the rotation direction acts on both the disk members 20 and 30, the fastening bolts and nuts are loosened, and the coupling is fixed. The power can be reduced.

２本の棒状体を複数の交差角度で連結可能であり、かつ、交差する２本の棒状体への取付作業が容易であるとともに取付後にも連結固定力を維持させやすい交差連結具が求められている。   There is a need for a cross-connecting tool that can connect two rod-shaped bodies at a plurality of crossing angles and that can be easily attached to two intersecting rod-shaped bodies and that can easily maintain the coupling fixing force after mounting. ing.

本発明に係る交差連結具は、
互いに交差する２本の棒状体どうしを連結する交差連結具であって、
対向して配置される一対の対向部と、一対の前記対向部どうしを接続する接続部と、を一体的に備え、
一対の前記対向部どうしの間に、２本の前記棒状体を、予め定められた設定交差角度範囲内の任意の交差角度で挟持して固定する。 The cross connector according to the present invention is
A cross-connecting tool that connects two rod-shaped bodies that cross each other,
A pair of opposing portions disposed opposite to each other and a connection portion connecting the pair of opposing portions;
Between the pair of opposing portions, the two rod-shaped bodies are clamped and fixed at an arbitrary crossing angle within a predetermined set crossing angle range.

この構成によれば、一対の対向部が両者間に２本の棒状体を設定交差角度範囲内の任意の交差角度で挟持して固定するので、２本の棒状体を複数の交差角度で連結することができる。このとき、一対の対向部と接続部とが一体的に形成される（以下、これらを合わせて「一体本体部」と称する）ので、交差する２本の棒状体への取り付けに際しては、単一部材である一体本体部だけを主に扱えば良い。よって、その取付作業が容易である。また、仮に振動等によって２本の棒状体の交差角度が変動したとしても、両対向部は、いずれも一体本体部の一部であるため相対回転しない。よって、一対の対向部どうしを例えばボルト・ナットで締結する場合であっても緩みが生じにくく、取付後にも連結固定力を維持させやすい。   According to this configuration, since the pair of opposing portions sandwich and fix two rod-shaped bodies between them at an arbitrary intersection angle within the set intersection angle range, the two rod-shaped bodies are connected at a plurality of intersection angles. can do. At this time, the pair of opposing portions and the connecting portion are integrally formed (hereinafter, these are collectively referred to as “integrated main body portion”). Only the integral main body, which is a member, may be mainly handled. Therefore, the attachment work is easy. Further, even if the crossing angle of the two rod-like bodies fluctuates due to vibration or the like, both opposing portions do not rotate relative to each other because they are both part of the integrated main body. Therefore, even when a pair of opposing portions are fastened with, for example, bolts and nuts, loosening is unlikely to occur, and the connection fixing force can be easily maintained even after attachment.

以下、本発明の好適な態様について説明する。但し、以下に記載する好適な態様例によって、本発明の範囲が限定される訳ではない。   Hereinafter, preferred embodiments of the present invention will be described. However, the scope of the present invention is not limited by the preferred embodiments described below.

１つの態様として、一対の前記対向部は、対向板部と前記対向板部の外縁に沿って立設する側板部とをそれぞれ含むとともに、前記側板部の立設端どうしが互いに向き合うように配置され、一方の前記対向部の前記側板部は、一方の前記棒状体における異なる２箇所にそれぞれ係止される一対の係止切欠部を有するとともに、他方の前記対向部の前記側板部は、当該側板部の延在方向に沿って延びる、他方の前記棒状体が複数の異なる姿勢で挿通可能な延伸切欠部を有すると好適である。   As one aspect, the pair of facing portions includes a facing plate portion and a side plate portion erected along an outer edge of the facing plate portion, and is arranged so that standing ends of the side plate portions face each other. The side plate portion of one of the facing portions has a pair of locking cutout portions that are respectively locked at two different positions in the one rod-shaped body, and the side plate portion of the other facing portion is It is preferable that the other rod-shaped body extending along the extending direction of the side plate portion has an extending cutout portion that can be inserted in a plurality of different postures.

この構成によれば、第１の棒状体における異なる２箇所を第１の対向部の側板部に設けられた一対の係止切欠部に係止させて、第１の棒状体に対する一体本体部の姿勢を安定化させることができる。この状態で、第２の対向部の側板部に設けられた延伸切欠部に第２の棒状体を複数の異なる姿勢で挿通させることにより、延伸切欠部の延在方向に沿った長さの制約内で、２本の棒状体を任意の交差角度で連結することができる。また、一対の対向部の側板部どうしが互いに向き合うので、交差する２本の棒状体を、係止切欠部の内縁と延伸切欠部の内縁とで互いに圧接しながら強固に挟持することができる。   According to this structure, two different places in the first rod-shaped body are locked to the pair of locking notches provided on the side plate portion of the first facing portion, and the integral main body portion with respect to the first rod-shaped body The posture can be stabilized. In this state, the length restriction along the extending direction of the extending notch is achieved by inserting the second rod-like body into the extending notch provided in the side plate portion of the second facing portion in a plurality of different postures. The two rod-shaped bodies can be connected at an arbitrary crossing angle. Further, since the side plate portions of the pair of opposing portions face each other, the two intersecting rod-like bodies can be firmly held while being pressed against each other between the inner edge of the locking notch portion and the inner edge of the extending notch portion.

１つの態様として、前記棒状体の外面に凹凸部が設けられ、前記係止切欠部及び前記延伸切欠部の少なくとも一方の内縁に、先端先細り状に形成されて前記凹凸部に係合する尖鋭係合部が形成されていると好適である。   As one aspect, a sharpened portion is provided with an uneven portion on the outer surface of the rod-shaped body, and is formed in a tapered shape at the inner edge of at least one of the locking notch portion and the extended notch portion and engages with the uneven portion. It is preferable that a joint is formed.

この構成によれば、係止切欠部の内縁の尖鋭係合部及び／又は延伸切欠部の内縁の尖鋭係合部が、棒状体の外面に設けられる凹凸部に喰い込むように係合される。よって、２本の棒状体の少なくとも一方に対する軸方向の位置ずれを有効に抑制することができ、交差する２本の棒状体を強固に連結固定することができる。   According to this configuration, the sharp engagement portion at the inner edge of the locking notch and / or the sharp engagement portion at the inner edge of the extending notch is engaged so as to bite into the uneven portion provided on the outer surface of the rod-shaped body. . Therefore, the axial displacement with respect to at least one of the two rod-shaped bodies can be effectively suppressed, and the two intersecting rod-shaped bodies can be firmly connected and fixed.

１つの態様として、少なくとも前記延伸切欠部の内縁に前記尖鋭係合部が形成されているとともに、前記延伸切欠部が、当該延伸切欠部の内縁の位置に応じて、２本の前記棒状体が互いに交差する交差位置からの離間距離が異なるように構成されていると好適である。   As one aspect, the sharp engagement portion is formed at least on the inner edge of the stretched cutout portion, and the stretched cutout portion includes two rod-like bodies according to the position of the inner edge of the stretched cutout portion. It is preferable that the distances from the intersecting positions where they intersect each other are different.

この構成によれば、延伸切欠部の尖鋭係合部が棒状体の外面の凹凸部に喰い込んだ状態で、延伸切欠部に挿通されている第２の棒状体の姿勢変化を規制することができる。よって、仮に振動が作用した場合等にも２本の棒状体の交差角度の変動自体を抑制することができ、取付後における連結固定力を良好に維持することができる。   According to this configuration, it is possible to regulate the posture change of the second rod-shaped body inserted through the stretched cutout portion in a state where the sharp engagement portion of the stretched cutout portion is bitten into the uneven portion of the outer surface of the rod-shaped body. it can. Therefore, even when vibration is applied, for example, the fluctuation of the crossing angle of the two rod-like bodies can be suppressed, and the connecting and fixing force after the attachment can be favorably maintained.

１つの態様として、一対の前記対向部は、対向板部と前記対向板部の外縁に沿って立設する側板部とをそれぞれ含み、一対の前記対向部のそれぞれの前記側板部は、平坦状に形成された平坦部を有し、前記接続部が、一対の前記対向部のそれぞれの前記平坦部と同一平面状に連続する状態又は面接触する状態で設けられていると好適である。   As one aspect, the pair of facing portions includes a facing plate portion and a side plate portion erected along an outer edge of the facing plate portion, and the side plate portions of the pair of facing portions are flat. It is preferable that the connecting portion is provided in a state of being in the same plane as the flat portion of each of the pair of opposing portions or in a surface contact state.

この構成によれば、一対の対向部どうしを接続する接続部を平坦状に形成することができる。よって、当該接続部をヒンジ部として機能させる場合に、接続部が例えば弧状に形成される構成と比較して、一対の対向部を容易に開閉させることができる。よって、交差する２本の棒状体に対する一体本体部の取付作業を容易に行うことができる。   According to this structure, the connection part which connects a pair of opposing parts can be formed in flat shape. Therefore, when making the said connection part function as a hinge part, compared with the structure by which a connection part is formed in arc shape, a pair of opposing part can be opened and closed easily. Therefore, it is possible to easily perform the attaching operation of the integrated main body portion to the two intersecting rod-shaped bodies.

１つの態様として、２本の前記棒状体が互いに交差する交差位置に対して前記接続部とは反対側で一対の前記対向部どうしを締結する単一の締結ユニットを備えると好適である。   As one aspect, it is preferable to provide a single fastening unit that fastens a pair of the opposing portions on the side opposite to the connection portion with respect to the intersection position where the two rod-shaped bodies intersect each other.

本発明では、交差連結具を構成する一対の対向部が接続部を介して一体的に構成されているので、接続部を支点として、上記の構成のように単一の締結ユニットを用いて一対の対向部どうしの間に２本の棒状体を挟持して固定することができる。よって、交差する２本の棒状体への取り付けに際して、一体本体部と１つの締結ユニットだけを扱えば良いので、その取付作業を極めて容易に行うことができる。また、交差位置に対して接続部とは反対側で締結するので、２本の棒状体をより強固かつ確実に固定することができる。   In the present invention, since the pair of facing portions constituting the cross connector are integrally formed via the connection portion, the pair is formed using the single fastening unit as described above with the connection portion as a fulcrum. Two rod-shaped bodies can be sandwiched and fixed between the opposing portions. Therefore, when attaching to the two intersecting rod-shaped bodies, it is only necessary to handle the integrated main body portion and one fastening unit, so that the attaching operation can be performed very easily. Moreover, since it fastens on the opposite side to a connection part with respect to an intersection position, two rod-shaped bodies can be fixed more firmly and reliably.

A cross-connector 1 can be provided. Hereinafter, the cross connector 1 of this embodiment will be described in detail.

なお、以下の説明において、交差連結具１を構成する各部材の説明における位置や方向等についての言及は、特に断らない限り、交差する２本の棒状体６に交差連結具１が取り付けられた状態での位置や方向等を意図しているものとする。また、以下の説明で用いる位置、方向、及び寸法等に関する用語（例えば「一致」、「直交」、「平行」、及び「同一」等）は、誤差（製造上許容され得る程度の誤差）による差異を有する状態も含む概念である。また、以下の説明で参照する図面においては、図示の容易化や理解の容易化等の観点から、縮尺や上下左右の寸法比率等が実際の製品とは異なる場合がある。   In addition, in the following description, the reference about the position, direction, etc. in description of each member which comprises the cross-connecting tool 1 was attached to the two crossed rod-shaped bodies 6 unless otherwise indicated. The position and direction in the state are intended. In addition, terms (for example, “match”, “orthogonal”, “parallel”, “same”, etc.) relating to the position, direction, dimensions, etc. used in the following description are based on errors (tolerable errors in manufacturing). It is a concept including a state having a difference. In the drawings referred to in the following description, the scale, the vertical / left / right dimensional ratio, and the like may be different from those of an actual product from the viewpoints of easy illustration and easy understanding.

The structure is shown. As an example, this support structure is formed by connecting attachment pieces 81 fixed to the four corners of the suspension device 8 to each of four suspension bolts 61 extending downward along the vertical direction from the structure. The suspension device 8 is fixed to each suspension bolt 61 by sandwiching the attachment piece 81 from above and below with a pair of nuts screwed to the suspension bolt 61. The suspended device 8 is, for example, an indoor unit of an air conditioner, a lighting device, a cable rack, or the like.

The counter plate portion 11 is formed in a flat plate shape. The counter plate portion 11 is formed in a circular shape (a perfect circle shape in this example) when viewed from the front (as viewed from a direction orthogonal to the flat surface constituting the counter plate portion 11). “Circular” means a substantially circular shape, and means a circular shape or a shape that can be regarded as a circular shape even if there is some distortion or irregular shape. “Circle” is a concept including a true circle, an ellipse, an oval, and a deformed circle such as an egg. The counter plate portion 11 is formed so as to have a shape of a partially cut circle formed by cutting out a part of a perfect circle (in this example, a central angle is approximately 90 °) in a straight line when viewed from the front. The counter plate portion 11 is formed with an insertion hole 12 through which the shaft portion of the fastening bolt 41 constituting the fastening unit 4 is inserted. The insertion hole 12 is formed in a region opposite to the connection portion 30 in the counter plate portion 11. The counter plate portion 11 is arranged to face the counter plate portion 21 of the second counter portion 20 in a parallel posture.

側板部１４は、対向板部１１の外縁に沿って立設するように設けられている。側板部１４は、対向板部１１に対して交差して延びる側壁部として構成されている。側板部１４は、対向板部１１に対して直交する方向に延びていても良いし、直交方向に対して傾斜する方向（例えば３０°〜６０°傾斜する方向）に延びていても良い。側板部１４は、対向板部１１の正面視形状に応じて、一部切欠円の円弧状部分に対応する弧状部１４Ａと、直線部分に対応する平坦部１４Ｂとを有する。本実施形態では、弧状部１４Ａは、対向板部１１に対して直交しつつ、対向板部１１の周囲を周回する方向に沿って延びるように形成されている。平坦部１４Ｂは、平坦状に形成されて対向板部１１に対して直交する状態に配置されている。側板部１４は、その立設端１４ｅが第二対向部２０側を向くように配置されている。   The side plate portion 14 is provided so as to stand along the outer edge of the opposing plate portion 11. The side plate portion 14 is configured as a side wall portion extending so as to intersect the counter plate portion 11. The side plate portion 14 may extend in a direction orthogonal to the counter plate portion 11 or may extend in a direction inclined with respect to the orthogonal direction (for example, a direction inclined by 30 ° to 60 °). The side plate portion 14 has an arcuate portion 14A corresponding to a partially cut-out circular arc portion and a flat portion 14B corresponding to a straight portion, depending on the shape of the opposing plate portion 11 when viewed from the front.

The locking cutout portion 15 is formed by cutting out in a concave shape from the standing end 14 e side of the side plate portion 14 toward the opposing plate portion 11 side. Two locking notches 15 are formed in the side plate 14. In the present embodiment, the locking notch portions are provided at two positions, that is, the position of the boundary portion between the arc-shaped portion 14A and the flat portion 14B in the side plate portion 14 and the position of the arc-shaped portion 14A having a phase difference of about 180 ° with respect to the position. 15 is formed. The locking notch 15 has a shape substantially corresponding to the outer shape of the first rod-shaped body 6A, and in this example, the opening is a U-shape when viewed from a direction orthogonal to the plate surface of the side plate 14. Is formed. As shown in FIG. 5, the pair of locking notches 15 are respectively locked at two different positions in the axial direction of the first rod-shaped body 6A. The first rod-like body 6 </ b> A is held in a fixed posture by the first facing portion 10 in a state where two axially different places are respectively locked to the pair of locking notches 15 of the side plate portion 14.

図２及び図３に示すように、第二対向部２０は、対向板部２１と、この対向板部２１から立設する側板部２４とを含む。対向板部２１は、平坦な板状に形成されている。対向板部２１は、正面視で（当該対向板部２１を構成する平坦面に直交する方向から見て）、円状（本例では真円状）に形成されている。対向板部２１は、正面視で真円の一部（本例では中心角がおよそ９０°の範囲）を直線状に切り欠いてなる一部切欠円の形状を呈するように形成されている。対向板部２１には、締結ユニット４を構成する締結ボルト４１の軸部が挿通される挿通孔２２が形成されている。挿通孔２２は、対向板部２１における接続部３０とは反対側の領域に形成されている。対向板部２１は、第一対向部１０の対向板部１１に対して、平行姿勢で対向するように配置されている。   As shown in FIGS. 2 and 3, the second facing portion 20 includes a facing plate portion 21 and a side plate portion 24 erected from the facing plate portion 21. The counter plate portion 21 is formed in a flat plate shape. The counter plate portion 21 is formed in a circular shape (a perfect circle shape in this example) when viewed from the front (as viewed from a direction orthogonal to the flat surface constituting the counter plate portion 21). The counter plate portion 21 is formed so as to have a shape of a partially cut circle formed by cutting out a portion of a perfect circle (in this example, the central angle is approximately 90 °) in a straight line when viewed from the front. The counter plate portion 21 is formed with an insertion hole 22 through which the shaft portion of the fastening bolt 41 constituting the fastening unit 4 is inserted. The insertion hole 22 is formed in a region on the opposite side of the connection portion 30 in the counter plate portion 21. The counter plate portion 21 is disposed to face the counter plate portion 11 of the first counter portion 10 in a parallel posture.

側板部２４は、対向板部２１の外縁に沿って立設するように設けられている。側板部２４は、対向板部２１に対して交差して延びる側壁部として構成されている。側板部２４は、対向板部２１に対して直交する方向に延びていても良いし、直交方向に対して傾斜する方向（例えば３０°〜６０°傾斜する方向）に延びていても良い。側板部２４は、対向板部２１の正面視形状に応じて、一部切欠円の円弧状部分に対応する弧状部２４Ａと、直線部分に対応する平坦部２４Ｂとを有する。本実施形態では、弧状部２４Ａは、対向板部２１に対して直交しつつ、対向板部２１の周囲を周回する方向に沿って延びるように形成されている。平坦部２４Ｂは、平坦状に形成されて対向板部２１に対して直交する状態に配置されている。側板部２４は、その立設端２４ｅが第一対向部１０側を向くように配置されている。こうして、一対の対向部１０，２０は、同一の基本的構成態様を備え、それぞれの側板部１４，２４の立設端１４ｅ，２４ｅどうしが互いに向き合うように配置されている。   The side plate portion 24 is provided so as to stand along the outer edge of the counter plate portion 21. The side plate portion 24 is configured as a side wall portion extending so as to intersect the counter plate portion 21. The side plate portion 24 may extend in a direction orthogonal to the opposing plate portion 21 or may extend in a direction inclined with respect to the orthogonal direction (for example, a direction inclined by 30 ° to 60 °). The side plate portion 24 has an arc-shaped portion 24A corresponding to a partially cut-out circular arc-shaped portion and a flat portion 24B corresponding to a straight-line portion according to the shape of the opposing plate portion 21 as viewed from the front. In the present embodiment, the arc-shaped portion 24 </ b> A is formed so as to extend along the direction of circling around the counter plate portion 21 while being orthogonal to the counter plate portion 21. The flat part 24 </ b> B is formed in a flat shape and is arranged in a state orthogonal to the counter plate part 21. The side plate portion 24 is disposed such that the standing end 24e faces the first facing portion 10 side. Thus, the pair of opposing portions 10 and 20 have the same basic configuration, and are arranged so that the standing ends 14e and 24e of the side plate portions 14 and 24 face each other.

側板部２４は延伸切欠部２５を有する。延伸切欠部２５は、側板部２４の立設端２４ｅ側から対向板部２１側に向かって凹状に切り欠いて形成されている。また、延伸切欠部２５は、側板部２４の延在方向に沿って延びる長穴状切欠部として形成されている。延伸切欠部２５は、側板部２４のおよそ全体に亘ってその延在方向に沿って連続して延びる単一の切欠部であっても良いし、側板部２４の延在方向に沿って分散する複数の切欠部であっても良い。本実施形態では、側板部２４の弧状部１４Ａにおける２箇所に、延伸切欠部２５がそれぞれ形成されている。それぞれの延伸切欠部２５は、弧状部１４Ａにおける中心角がおよそ９０°の範囲に亘って延びるように形成されている。一対の延伸切欠部２５は、位相差がおよそ１８０°となる位置関係で形成されている。一対の延伸切欠部２５には、第二棒状体６Ｂにおける軸方向の異なる２箇所がそれぞれ配置（挿通）される。第二棒状体６Ｂは、軸方向の異なる２箇所が側板部２４の一対の延伸切欠部２５にそれぞれ挿通された状態で、各延伸切欠部２５の開口幅（側板部２４の延在方向に沿う開口幅）の制約内で、複数の異なる姿勢を取り得る（図５を参照）。   The side plate portion 24 has a stretched cutout portion 25. The extending cutout portion 25 is formed by cutting out in a concave shape from the standing end 24e side of the side plate portion 24 toward the opposing plate portion 21 side. Further, the extending cutout portion 25 is formed as an elongated hole cutout portion extending along the extending direction of the side plate portion 24. The extending cutout 25 may be a single cutout extending continuously along the extending direction over substantially the entire side plate 24, or is distributed along the extending direction of the side plate 24. A plurality of notches may be provided. In the present embodiment, extending cutout portions 25 are formed at two locations in the arc-shaped portion 14A of the side plate portion 24, respectively. Each extending notch 25 is formed so that the central angle in the arcuate portion 14A extends over a range of approximately 90 °. The pair of extending cutouts 25 are formed in a positional relationship where the phase difference is approximately 180 °. In the pair of extending cutout portions 25, two different portions in the axial direction of the second rod-like body 6B are respectively arranged (inserted). The second rod-like body 6B has an opening width (in the extending direction of the side plate portion 24) of each extended cutout portion 25 in a state where two axially different places are respectively inserted into the pair of extended cutout portions 25 of the side plate portion 24. Within the constraint of (opening width), a plurality of different postures can be taken (see FIG. 5).

図２及び図３に示すように、接続部３０は、第一対向部１０と第二対向部２０とを接続する。接続部３０は、第一対向部１０の側板部１４の平坦部１４Ｂと、第二対向部２０の側板部２４の平坦部２４Ｂとを接続する。接続部３０は、平坦な板状に形成されている。本実施形態では、接続部３０は、第一対向部１０及び第二対向部２０と継ぎ目なく連続して設けられており、両平坦部１４Ｂ，２４Ｂと同一平面状に連続する状態で設けられている。このような一体接続部３１からなる接続部３０は、第一対向部１０と第二対向部２０とを開閉自在に接続するヒンジ部としても機能する。このため、平坦状の接続部３０が同じく平坦状の平坦部１４Ｂと平坦部２４Ｂとを接続する構成であれば、両対向部１０，２０を容易に開閉させることができるので好適である。   As shown in FIGS. 2 and 3, the connection part 30 connects the first facing part 10 and the second facing part 20. The connecting portion 30 connects the flat portion 14B of the side plate portion 14 of the first facing portion 10 and the flat portion 24B of the side plate portion 24 of the second facing portion 20. The connection part 30 is formed in a flat plate shape. In the present embodiment, the connection part 30 is provided continuously with the first opposing part 10 and the second opposing part 20 and is provided in a state where it is continuous with the flat parts 14B and 24B in the same plane. Yes. The connection part 30 which consists of such an integral connection part 31 functions also as a hinge part which connects the 1st opposing part 10 and the 2nd opposing part 20 so that opening and closing is possible. For this reason, if the flat connection part 30 is the structure which connects the flat part 14B and the flat part 24B which are also flat, it is suitable in order that the both opposing parts 10 and 20 can be opened and closed easily.

互いに同一の基本的構成態様を備える一対の対向部１０，２０が接続部３０で一体的に接続された一体本体部３は、全体としてカスタネット状に形成されている。この一体本体部３を交差する２本の棒状体６に取り付けるには、以下のようにすれば良い。まず、接続部３０を基点として第一対向部１０と第二対向部２０とを半開きの状態とする。なお、一体本体部３は、外力が作用しない無加圧状態で半開きの状態となるように構成されていても良く、この場合には特段の操作は必要ない。次に、接続部３０とは反対側の開放端側から、２本の棒状体６を第一対向部１０と第二対向部２０との対向領域に収めるように、一体本体部３を２本の棒状体６の配置面に沿って外挿する。このとき、単一部材である一体本体部３だけを扱えば良いので、例えば第一対向部１０と第二対向部２０とが互いに独立した別部材とされる構成と比較して、作業性が非常に良好である。   The integrated main body portion 3 in which a pair of facing portions 10 and 20 having the same basic configuration is integrally connected by a connection portion 30 is formed in a castanet shape as a whole. In order to attach the integrated main body 3 to the two rod-like bodies 6 that intersect, the following may be performed. First, the first facing portion 10 and the second facing portion 20 are set in a half-open state with the connection portion 30 as a base point. The integrated main body 3 may be configured to be in a half-open state in a non-pressurized state where no external force is applied. In this case, no special operation is required. Next, from the open end side opposite to the connection part 30, the two integrated main body parts 3 are arranged so that the two rod-like bodies 6 are accommodated in the opposing region between the first opposing part 10 and the second opposing part 20. Extrapolated along the arrangement surface of the rod-shaped body 6. At this time, since it is only necessary to handle the integrated main body 3 that is a single member, for example, the workability is improved as compared with a configuration in which the first facing portion 10 and the second facing portion 20 are separate members independent of each other. Very good.

この状態で、第一棒状体６Ａにおける軸方向の異なる２箇所を、第一対向部１０の側板部１４に形成された一対の係止切欠部１５にそれぞれ係止させる（図４及び図５を参照）。この第一棒状体６Ａと一対の係止切欠部１５との係止操作により、第一棒状体６Ａに対する一体本体部３（交差連結具１）の取付姿勢が定まる。また、この状態で、第二棒状体６Ｂは、第一棒状体６Ａとの交差角度に応じた姿勢で、第二対向部２０の側板部２４に形成された延伸切欠部２５に配置（挿通）される。延伸切欠部２５は側板部２４の延在方向に沿って延びる長穴状に形成されているので、その延在方向の長さに応じた制約内で、第二棒状体６Ｂは任意の姿勢を取り得る。こうして、一体本体部３を用いて、一対の対向部１０，２０どうしの間に、２本の棒状体６を、予め定められた設定交差角度範囲ＡＲ内の任意の交差角度で挟持する。   In this state, the two different axial directions of the first rod-like body 6A are respectively locked by the pair of locking notches 15 formed on the side plate portion 14 of the first facing portion 10 (see FIGS. 4 and 5). reference). By the locking operation between the first rod-shaped body 6A and the pair of locking notches 15, the mounting posture of the integrated main body 3 (cross connector 1) with respect to the first rod-shaped body 6A is determined. Further, in this state, the second rod-like body 6B is arranged (inserted) in the extending cutout portion 25 formed in the side plate portion 24 of the second facing portion 20 in a posture corresponding to the intersection angle with the first rod-like body 6A. Is done. Since the extending cutout portion 25 is formed in an elongated hole shape extending along the extending direction of the side plate portion 24, the second rod-like body 6B has an arbitrary posture within the restriction according to the length in the extending direction. I can take it. In this way, using the integrated main body 3, the two rod-like bodies 6 are sandwiched between the pair of facing portions 10 and 20 at an arbitrary crossing angle within a predetermined set crossing angle range AR.

なお、設定交差角度範囲ＡＲは、延伸切欠部２５の延在方向一方側（係止切欠部１５に近い側）の側縁に第二棒状体６Ｂが当接する状態での交差角度Ａ１以上、延伸切欠部２５の延在方向他方側（係止切欠部１５から遠い側）の側縁に第二棒状体６Ｂが当接する状態での交差角度Ａ２以下の範囲である（図５を参照）。２本の棒状体６の交差角度を設定交差角度範囲ＡＲ内で変更する場合には、第一棒状体６Ａ及び一体本体部３の位置を固定したままで、延伸切欠部２５の中で第二棒状体６Ｂを姿勢変更させれば良い。本実施形態の交差連結具１は、一対の対向部１０，２０の相対位置関係を一定に維持したままで、２本の棒状体６の交差角度を変更することができる。   The set intersection angle range AR is equal to or greater than the intersection angle A1 in a state in which the second rod-like body 6B is in contact with the side edge on one side in the extending direction of the extending notch 25 (the side closer to the locking notch 15). The crossing angle A2 or less in a state where the second rod-like body 6B is in contact with the side edge of the other side in the extending direction of the notch 25 (the side far from the locking notch 15) (see FIG. 5). When changing the crossing angle of the two rod-shaped bodies 6 within the set crossing angle range AR, the positions of the first rod-shaped body 6A and the integrated main body 3 are fixed, and the second notch 25 in the stretched cutout 25. The posture of the rod-like body 6B may be changed. The cross connector 1 of the present embodiment can change the crossing angle of the two rod-like bodies 6 while maintaining the relative positional relationship between the pair of facing portions 10 and 20 constant.

最後に、対をなす締結ボルト４１と締結ナット４２とを含む締結ユニット４を用いて、第一対向部１０と第二対向部２０とを締結する。締結ボルト４１の軸部を、一体本体部３に対して一方側から対向板部１１の挿通孔１２及び対向板部２１の挿通孔２２に挿通させ、一体本体部３の他方側に突出する締結ボルト４１の先端部に締結ナット４２を螺合させて締め付ける。これにより、図４に示すように、交差状態で配置される２本の棒状体６を、係止切欠部１５の内縁１５ｅと延伸切欠部２５の内縁２５ｅとで圧接して強固に挟持する。こうして、交差する２本の棒状体６どうしが強固に連結される。   Finally, the 1st opposing part 10 and the 2nd opposing part 20 are fastened using the fastening unit 4 containing the fastening bolt 41 and the fastening nut 42 which make a pair. The fastening bolt 41 is inserted through the insertion hole 12 of the opposing plate portion 11 and the insertion hole 22 of the opposing plate portion 21 from one side with respect to the integral main body portion 3, and is fastened to protrude to the other side of the integral main body portion 3. A fastening nut 42 is screwed onto the tip of the bolt 41 and tightened. As a result, as shown in FIG. 4, the two rod-like bodies 6 arranged in an intersecting state are pressed and firmly sandwiched between the inner edge 15 e of the locking notch 15 and the inner edge 25 e of the extended notch 25. Thus, the two intersecting rod-like bodies 6 are firmly connected.

締結ユニット４は、２本の棒状体６が互いに交差する交差位置Ｘ（図５を参照）に対して、接続部３０とは反対側で一対の対向部１０，２０どうしを締結固定する。接続部３０が１つの支点として機能するので、単一の締結ユニット４を用いて、一対の対向部１０，２０どうしの間に２本の棒状体６を挟持して固定することができる。固定時に扱う締結ユニット４が一組だけで良いので、固定作業の作業性も非常に良好である。また、交差位置Ｘに対して接続部３０とは反対側で締結するので、２本の棒状体６をより強固かつ確実に固定することができる。   The fastening unit 4 fastens and fixes the pair of facing portions 10 and 20 on the side opposite to the connection portion 30 with respect to an intersection position X (see FIG. 5) where the two rod-like bodies 6 intersect each other. Since the connecting portion 30 functions as one fulcrum, the two rod-like bodies 6 can be sandwiched and fixed between the pair of facing portions 10 and 20 using the single fastening unit 4. Since only one set of the fastening unit 4 to be handled at the time of fixing is required, the workability of the fixing work is very good. Moreover, since it fastens on the opposite side to the connection part 30 with respect to the crossing position X, the two rod-shaped bodies 6 can be fixed more firmly and reliably.

締結ユニット４を構成する締結ボルト４１と締結ナット４２とは、１部品である一体本体部３における異なる２箇所（具体的には第一対向部１０の対向板部１１と第二対向部２０の対向板部２１）に圧接される。このため、仮に振動等によって２本の棒状体６の交差角度が変動したとしても、締結ボルト４１と締結ナット４２とは、締まり方向にも緩み方向にも相対回転することがない。よって、締結ボルト４１と締結ナット４２との間に緩みが生じるのを確実性高く防止することができ、取付後にも連結固定力を高く維持することができる。   The fastening bolts 41 and the fastening nuts 42 constituting the fastening unit 4 are two different parts (specifically, the opposing plate part 11 of the first opposing part 10 and the second opposing part 20 of the integrated opposing main body part 3). It is pressed against the opposing plate portion 21). For this reason, even if the crossing angle of the two rod-like bodies 6 fluctuates due to vibration or the like, the fastening bolt 41 and the fastening nut 42 do not rotate relative to each other in either the tightening direction or the loosening direction. Therefore, it is possible to prevent the looseness between the fastening bolt 41 and the fastening nut 42 with high certainty, and the connection fixing force can be kept high even after the attachment.

ところで、図６に示すように、棒状体６の外面には凹凸部６４が設けられている。本実施形態のように棒状体６が吊りボルト６１やブレースボルト６２で構成される場合には、軸方向に沿って交互に設けられるネジ山とネジ溝とによって凹凸部６４が形成される。本実施形態では、図７に示すように、凹凸部６４（具体的にはネジ溝）に係合する尖鋭係合部１６が、係止切欠部１５の内縁１５ｅに形成されている。同様に、凹凸部６４（具体的にはネジ溝）に係合する尖鋭係合部２６が、延伸切欠部２５の内縁２５ｅに形成されている。尖鋭係合部１６，２６は、先端先細り状に形成されて凹凸部６４に係合している。尖鋭係合部１６は、係止切欠部１５の形成領域に位置する側板部１４を、内縁１５ｅに向かうに従って板厚を薄くするようにＣ面カット状に形成されている。尖鋭係合部２６は、延伸切欠部２５の形成領域に位置する側板部２４を、内縁２５ｅに向かうに従って板厚を薄くするようにＣ面カット状に形成されている。なお、尖鋭係合部１６，２６は、完全に尖るように鋭利に形成されても良いし、少なくとも凹凸部６４に係合可能であれば内縁１５ｅ，２５ｅ側に平坦面が残存する状態に（なまくらに）形成されても良い。   By the way, as shown in FIG. 6, the uneven | corrugated | grooved part 64 is provided in the outer surface of the rod-shaped body 6. As shown in FIG. When the rod-like body 6 is composed of the suspension bolt 61 and the brace bolt 62 as in the present embodiment, the concavo-convex portion 64 is formed by the threads and the screw grooves provided alternately along the axial direction. In the present embodiment, as shown in FIG. 7, a sharp engagement portion 16 that engages with the concavo-convex portion 64 (specifically, a thread groove) is formed on the inner edge 15 e of the locking notch portion 15. Similarly, a sharp engagement portion 26 that engages with the concavo-convex portion 64 (specifically, a thread groove) is formed on the inner edge 25 e of the extended cutout portion 25. The sharp engagement portions 16 and 26 are formed in a tapered shape at the tip and engage with the concavo-convex portion 64. The sharp engagement portion 16 is formed in a C-plane cut shape so that the side plate portion 14 located in the formation region of the locking notch 15 is made thinner toward the inner edge 15e. The sharp engagement portion 26 is formed in a C-plane cut shape so that the side plate portion 24 located in the region where the extended cutout portion 25 is formed becomes thinner toward the inner edge 25e. The sharp engagement portions 16 and 26 may be formed sharply so as to be completely sharp, or if a flat surface remains on the inner edges 15e and 25e side as long as the sharp engagement portions 16 and 26 can be engaged with at least the concave and convex portions 64 ( May be formed).

このような尖鋭係合部１６，２６を備えることで、係止切欠部１５の内縁１５ｅの尖鋭係合部１６は、第一棒状体６Ａの外面の凹凸部６４に喰い込むように係合される。同様に、延伸切欠部２５の内縁２５ｅの尖鋭係合部２６は、第二棒状体６Ｂの外面の凹凸部６４に喰い込むように係合される。よって、２本の棒状体６のそれぞれに対する軸方向の位置ずれを有効に抑制することができ、交差連結具１を用いて、交差する２本の棒状体６を強固に連結固定することができる。   By providing such sharp engagement portions 16 and 26, the sharp engagement portion 16 of the inner edge 15e of the locking notch 15 is engaged so as to bite into the uneven portion 64 on the outer surface of the first rod-shaped body 6A. The Similarly, the sharp engagement portion 26 of the inner edge 25e of the extending cutout portion 25 is engaged so as to bite into the uneven portion 64 on the outer surface of the second rod-shaped body 6B. Therefore, the positional deviation in the axial direction with respect to each of the two rod-like bodies 6 can be effectively suppressed, and the two intersecting rod-like bodies 6 can be firmly connected and fixed using the cross connector 1. .

なお、延伸切欠部２５は、当該延伸切欠部２５の内縁２５ｅの位置によらずに２本の棒状体６の交差位置Ｘからの離間距離が同一となるように構成されても良いし、内縁２５ｅの位置に応じて交差位置Ｘからの離間距離が異なるように構成されても良い。前者の構成は、例えば対向板部１１，２１の円形部分の中心と交差位置Ｘとを一致させることで実現できる。このような構成では、第二棒状体６Ｂの外面の凹凸部６４に尖鋭係合部２６が喰い込んだ状態のまま、第二棒状体６Ｂの姿勢変更を行うことができる。一方、後者の構成は、例えば対向板部１１，２１の円形部分の中心と交差位置Ｘとを偏心させることで実現できる。このような構成では、尖鋭係合部２６と凹凸部６４とが突っ張り合うことによって第二棒状体６Ｂの姿勢変動（２本の棒状体６の交差角度の変動）が抑止されるので、締結ユニット４の緩みをより確実に防止でき、取付後の連結固定力をより一層高く維持できる。   In addition, the extending | stretching notch part 25 may be comprised so that the separation distance from the intersection position X of the two rod-shaped bodies 6 may become the same irrespective of the position of the inner edge 25e of the said extending | stretching notch part 25, and an inner edge The separation distance from the intersection position X may be different depending on the position of 25e. The former configuration can be realized, for example, by matching the center of the circular portion of the opposing plate portions 11 and 21 with the intersection position X. In such a configuration, the posture of the second rod-shaped body 6B can be changed with the sharp engagement portion 26 biting into the concavo-convex portion 64 on the outer surface of the second rod-shaped body 6B. On the other hand, the latter configuration can be realized, for example, by decentering the center of the circular portion of the opposing plate portions 11 and 21 and the intersection position X. In such a configuration, the posture engagement of the second rod-shaped body 6B (the variation in the crossing angle of the two rod-shaped bodies 6) is suppressed by the sharp engagement portion 26 and the concavo-convex portion 64 sticking to each other. 4 can be more reliably prevented, and the connecting and fixing force after mounting can be maintained even higher.

最後に、交差連結具のその他の実施形態について説明する。なお、以下のそれぞれの実施形態で開示される構成は、矛盾が生じない限り、他の実施形態で開示される構成と組み合わせて適用することも可能である。 [Other Embodiments]
Finally, other embodiments of the cross connector will be described. Note that the configurations disclosed in the following embodiments can be applied in combination with the configurations disclosed in other embodiments as long as no contradiction arises.

（１）上記の実施形態では、接続部３０が第一対向部１０及び第二対向部２０と同一平面状に連続する状態で設けられた一体接続部３１で構成される例について説明した。しかし、本発明の実施形態はこれに限定されない。例えば図８に示すように、第一対向部１０及び第二対向部２０とは別体の接続板部３２で接続部３０が構成されても良い。接続板部３２は、例えば高剛性の板状部材やバネ板部材等であって良い。接続板部３２からなる接続部３０は、両対向部１０，２０のそれぞれの平坦部１４Ｂ，２４Ｂと面接触する状態で設けられ、溶接や蝋付け等によって接合されて両対向部１０，２０と一体化されると良い。また、両対向部１０，２０と接続部３０とは、カシメ等によって一体化されても良い。なお、接続部３０は、ヒンジ部として機能しやすいように、例えばヘアピン状の屈曲部等からなる易変形部を備えても良い。 (1) In the above-described embodiment, the example in which the connection portion 30 includes the integrated connection portion 31 provided in a state where the connection portion 30 is continuous with the first facing portion 10 and the second facing portion 20 has been described. However, the embodiment of the present invention is not limited to this. For example, as shown in FIG. 8, the connection portion 30 may be configured by a connection plate portion 32 that is separate from the first facing portion 10 and the second facing portion 20. The connection plate portion 32 may be, for example, a highly rigid plate member or a spring plate member.
