本開示は、コネクタに関する。 The present disclosure relates to a connector.
円筒状の2つの棒状部材の一方の外面と他方の端部とを連結するためのコネクタが知られている。特許文献1には、互いに独立した部品である一対のコネクタ要素からなるコネクタが開示されている。各コネクタ要素の軸方向一端には、棒状部材の外面に圧接する把持爪部と、分割面と、を備えた頭部が設けられ、軸方向他端には、棒状部材の端部に挿入された状態で内面に圧接する円柱状の外周面と、螺旋状係合面と、を備えた押圧部が設けられている。各コネクタ要素は、頭部の分割面が対向するように配置され、押圧部の螺旋状係合面が係合した状態で組み合わせられている。当該コネクタは、一対のコネクタ要素がボルト・ナットによって締結されることにより、各コネクタ要素の把持爪部が相互に接近する一方、各コネクタ要素の押圧部の外周面が相互に離間するように構成されている。 A connector for connecting one outer surface of two cylindrical rod-like members and the other end is known. Patent Document 1 discloses a connector including a pair of connector elements that are parts independent of each other. One end of each connector element in the axial direction is provided with a head provided with a gripping claw portion that presses against the outer surface of the rod-shaped member and a split surface, and the other axial end is inserted into the end of the rod-shaped member. A pressing portion having a cylindrical outer peripheral surface that is in pressure contact with the inner surface and a helical engagement surface is provided. Each connector element is arranged so that the split surfaces of the heads face each other, and are combined in a state where the helical engagement surfaces of the pressing portions are engaged. The connector is configured such that when a pair of connector elements are fastened by bolts and nuts, the gripping claws of each connector element approach each other while the outer peripheral surfaces of the pressing parts of each connector element are separated from each other. Has been.
このような構成によれば、ボルト・ナットによってコネクタの一箇所を締結するだけで、2つの棒状部材の一方の外面と他方の端部とを連結することができる。しかも、一方の棒状部材の外面への連結力と、他方の棒状部材の内面への連結力と、が偏りにくくなるため、連結力が不足したり過剰となったりすることが抑制される。 According to such a configuration, it is possible to connect one outer surface of the two rod-shaped members and the other end only by fastening one place of the connector with the bolt and nut. In addition, since the connecting force to the outer surface of one rod-shaped member and the connecting force to the inner surface of the other rod-shaped member are less likely to be biased, the connection force is suppressed from becoming insufficient or excessive.
しかしながら、特許文献1のコネクタは、構造が複雑であり、重くなってしまう問題があった。
本開示の一局面は、簡素かつ軽量な構成のコネクタを提供することを目的としている。
However, the connector of Patent Document 1 has a complicated structure and has a problem of becoming heavy.

It is comprised so that it may fix to a 2nd rod-shaped member by press-contacting to the inner surface of a member. Further, the urging mechanism is configured to apply an external force in a direction in which the portions closer to the first side end than the interval holding portion in the pair of opposed plate portions are brought closer to each other to the pair of opposed plate portions.
このような構成によれば、付勢機構による外力が一対の対向部に加えられると、第1側端部が互いに近づき、またこれと同時に、間隔保持部の作用により、第2側端部が互いに離れる。その結果、第1側端部が第1の棒状部材の外面に圧接し、第2側端部が第2の棒状部材の内面に圧接する。このような作用が、一対の対向板部と、間隔保持部と、付勢機構とによって実現される。したがって、簡素かつ軽量な構成のコネクタを提供することが可能となる。 According to such a configuration, when an external force by the urging mechanism is applied to the pair of opposed portions, the first side end portions approach each other, and at the same time, the second side end portion is moved by the action of the interval holding portion. Separate from each other. As a result, the first side end is pressed against the outer surface of the first bar-shaped member, and the second side end is pressed against the inner surface of the second bar-shaped member. Such an action is realized by the pair of opposing plate portions, the interval holding portion, and the urging mechanism. Therefore, it is possible to provide a connector having a simple and lightweight configuration.
本開示の一態様は、間隔保持部の両側の端部が、一対の対向板部のそれぞれの対向面における中央部に接続されてもよい。また、一対の対向板部及び間隔保持部が、単一の部品として構成されていてもよい。このような構成によれば、一対の対向板部が独立した部品として構成される場合と比較して、より簡素な構成のコネクタを提供することが可能となる。 In one aspect of the present disclosure, the end portions on both sides of the interval holding portion may be connected to the central portion of each of the opposing surfaces of the pair of opposing plate portions. Moreover, a pair of opposing board part and space | interval holding | maintenance part may be comprised as a single component.

According to such a structure, it becomes possible to stabilize the deformation | transformation aspect of a pair of opposing part by the external force by an urging | biasing mechanism being applied to a pair of opposing part.
本開示の一態様は、第1側端部、第2側端部及び間隔保持部における、特定の方向に垂直な断面形状が一定であってもよい。このような構成によれば、比較的簡易な方法でコネクタを製造することが可能となる。 In one aspect of the present disclosure, the first side end, the second side end, and the interval holding unit may have a constant cross-sectional shape perpendicular to a specific direction. According to such a configuration, the connector can be manufactured by a relatively simple method.
本開示の一態様は、第1側端部が、一対の対向板部のそれぞれの先端が互いに対向するように湾曲した板状であってもよい。また、第2側端部が、一対の対向板部のそれぞれが互いに間隔を空けて配置された平板状であってもよい。このような構成によれば、湾曲した板状の第1側端部が第1の棒状部材の外面に圧接し、平板状の第2側端部が第2の棒状部材の内面に圧接する。このような作用が、板状の端部によって実現される。したがって、簡素かつ軽量な構成でありながら連結力の強いコネクタを提供することが可能となる。 In one aspect of the present disclosure, the first side end portion may be a plate shape that is curved so that the tips of the pair of opposing plate portions face each other. Further, the second side end portion may have a flat plate shape in which each of the pair of opposed plate portions is arranged with a space therebetween. According to such a configuration, the curved plate-like first side end is pressed against the outer surface of the first bar-shaped member, and the flat plate-like second side end is pressed against the inner surface of the second bar-shaped member. Such an action is realized by the plate-like end portion. Therefore, it is possible to provide a connector having a strong coupling force while having a simple and lightweight configuration.
本開示の別の態様は、円筒状の2つの棒状部材の一方の外面と他方の端部とを連結するためのコネクタであって、一対の対向板部と、間隔保持部と、付勢機構と、を備えている。一対の対向板部は、互いに間隔を空けて対向する対向面を有する。間隔保持部は、一対の対向板部のそれぞれの対向面における第1の方向に沿った中央部同士の間隔を保つ。付勢機構は、一対の対向板部に外力を加える。棒状部材の外面は、棒状部材の中心軸に沿った複数の溝を有する。棒状部材の内面は、複数の溝の裏側となる位置に、棒状部材の中心軸に沿った複数の突条を有する。第1の方向に沿った一対の対向板部の両側の端部である第1側端部及び第2側端部のうち、第1側端部は、一対の対向板部のそれぞれの先端が互いに対向するように湾曲した板状であって、複数の溝に挿入されて棒状部材の外面を挟んだ状態で棒状部材の外面に圧接することで棒状部材に固定されるように構成されている。第2側端部は、一対の対向板部のそれぞれが互いに間隔を空けて配置された平板状であって、棒状部材の端部に挿入された状態で複数の突条に圧接することで棒状部材に固定されるように構成されている。第1の方向と直交する第2の方向に沿った間隔保持部の両側の端部は、一対の対向板部のそれぞれの対向面における第1の方向に沿った中央部に接続されている。間隔保持部は、第1の方向及び第2の方向のいずれにも直交する第3の方向に沿った交線で一対の対向板部のそれぞれの対向面と交わる板状である。一対の対向板部及び間隔保持部は、単一の部品として構成されている。付勢機構は、一対の対向板部における間隔保持部よりも第1側端部寄りの部分を互いに近づける向きの外力を、一対の対向板部に加えるように構成されている。 Another aspect of the present disclosure is a connector for connecting one outer surface and two other end portions of two cylindrical rod-shaped members, and includes a pair of opposing plate portions, a spacing holding portion, and an urging mechanism. And. A pair of opposing board part has the opposing surface which mutually opposes at intervals. The interval holding unit maintains the interval between the central portions along the first direction on the opposing surfaces of the pair of opposing plate portions. The urging mechanism applies an external force to the pair of opposing plate portions. The outer surface of the rod-shaped member has a plurality of grooves along the central axis of the rod-shaped member. The inner surface of the rod-shaped member has a plurality of protrusions along the central axis of the rod-shaped member at a position on the back side of the plurality of grooves. Of the first side end and the second side end that are the ends on both sides of the pair of opposing plate portions along the first direction, the first side end portion is the tip of each of the pair of opposing plate portions. The plate is curved so as to face each other, and is configured to be fixed to the rod-like member by being pressed into the outer surface of the rod-like member while being inserted into the plurality of grooves and sandwiching the outer surface of the rod-like member. . The second side end portion is a flat plate shape in which each of the pair of opposed plate portions is arranged with a space between each other, and is pressed into contact with the plurality of protrusions in a state of being inserted into the end portion of the rod-shaped member. It is comprised so that it may be fixed to a member. The end portions on both sides of the interval holding portion along the second direction orthogonal to the first direction are connected to the center portion along the first direction on each of the opposing surfaces of the pair of opposing plate portions. The interval holding portion has a plate shape that intersects with the opposing surfaces of the pair of opposing plate portions along an intersecting line along a third direction orthogonal to both the first direction and the second direction. The pair of opposing plate portions and the interval holding portion are configured as a single component. The urging mechanism is configured to apply an external force in a direction to bring the portions closer to the first side end portion closer to each other than the interval holding portion in the pair of opposed plate portions to the pair of opposed plate portions.
このような構成によれば、付勢機構による外力が一対の対向部に加えられると、第1側端部が互いに近づき、またこれと同時に、間隔保持部の作用により、第2側端部が互いに離れる。その結果、第1側端部が一方の棒状部材の外面に圧接し、第2側端部が他方の棒状部材の内面に圧接する。このような作用が、単一の部品として構成されている一対の対向板部及び間隔保持部と、付勢機構とによって実現される。したがって、簡素かつ軽量な構成のコネクタを提供することが可能となる。また、間隔保持部が、第3の方向に沿った交線で一対の対向板部のそれぞれの対向面と交わる板状であるため、付勢機構による外力が一対の対向部に加えられることによる一対の対向部の変形態様を安定させることが可能となる。しかも、棒状部材の外面が複数の溝を有し、棒状部材の内面が複数の凸状を有するため、第1側端部及び第2側端部の形状を簡素かつ小型にすることができる。 According to such a configuration, when an external force by the urging mechanism is applied to the pair of opposed portions, the first side end portions approach each other, and at the same time, the second side end portion is moved by the action of the interval holding portion. Separate from each other. As a result, the first side end is in pressure contact with the outer surface of one rod-shaped member, and the second side end is in pressure contact with the inner surface of the other rod-shaped member. Such an action is realized by a pair of opposing plate portions and interval holding portions configured as a single component, and an urging mechanism. Therefore, it is possible to provide a connector having a simple and lightweight configuration. Moreover, since the space | interval holding | maintenance part is plate shape which cross | intersects each opposing surface of a pair of opposing board part in the intersection line along a 3rd direction, it is because the external force by an urging | biasing mechanism is applied to a pair of opposing part It becomes possible to stabilize the deformation | transformation aspect of a pair of opposing part. And since the outer surface of a rod-shaped member has a some groove | channel and the inner surface of a rod-shaped member has a some convex shape, the shape of a 1st side edge part and a 2nd side edge part can be made simple and small.
本開示の一態様は、間隔保持部の板厚が、一対の対向板部のそれぞれの板厚よりも薄くてもよい。このような構成によれば、付勢機構による外力が一対の対向部に加えられることにより、第1側端部及び第2側端部を変位しやすくすることが可能となる。 In one aspect of the present disclosure, the plate thickness of the interval holding unit may be smaller than the plate thickness of each of the pair of opposed plate units. According to such a configuration, it is possible to easily displace the first side end and the second side end by applying an external force from the urging mechanism to the pair of opposing portions.
本開示の一態様は、第1側端部、第2側端部及び間隔保持部における、第3の方向に垂直な断面形状が一定であってもよい。このような構成によれば、比較的簡易な方法でコネクタを製造することが可能となる。 In one aspect of the present disclosure, the first side end, the second side end, and the interval holding unit may have a constant cross-sectional shape perpendicular to the third direction. According to such a configuration, the connector can be manufactured by a relatively simple method.
本開示の一態様は、複数の突条が、棒状部材の内面の周方向に沿って等間隔に配置された4つの突条であってもよい。このような構成によれば、平板状の第2側端部でありながら、第2側端部の第3の方向に沿った両側が、それぞれ突条に圧接するように構成することが可能となる。このため、連結力の強いコネクタを提供することが可能となる。 One aspect of the present disclosure may be four ridges in which the plurality of ridges are arranged at equal intervals along the circumferential direction of the inner surface of the rod-shaped member. According to such a configuration, both sides along the third direction of the second side end portion can be configured to be in pressure contact with the protrusions, respectively, while being the flat plate-like second side end portion. Become. For this reason, it is possible to provide a connector having a strong coupling force.
本開示の一態様は、付勢機構が、ボルトと、ボルトと螺合可能なナットと、を有してもよい。また、一対の対向板部がそれぞれ、間隔保持部を挟んだ両側のうち第1側端部の側に、ボルトの軸部を挿通するための貫通孔を有してもよい。このような構成によれば、一対の対向板部に外力を加える付勢機構を、簡素な構成で提供することが可能となる。 In one embodiment of the present disclosure, the biasing mechanism may include a bolt and a nut that can be screwed to the bolt. Moreover, a pair of opposing board part may have a through-hole for inserting the axial part of a volt | bolt in the side of the 1st side edge part among the both sides which pinched | interposed the space | interval holding | maintenance part, respectively. According to such a configuration, it is possible to provide an urging mechanism that applies an external force to the pair of opposed plate portions with a simple configuration.
本開示の一態様は、ボルトの頭部及びナットのうち少なくとも一方が、多角形状であってもよい。また、一対の対向板部が、棒状部材に対する第2側端部の挿入量を規制しかつボルトの頭部又はナットの回転を規制するためのリブを有してもよい。このような構成によれば、一対の対向板部と棒状部材との位置決め及びボルトの頭部又はナットの回転規制の2つの機能を有するリブを有するコネクタを提供することが可能となる。 In one aspect of the present disclosure, at least one of the bolt head and the nut may be polygonal. Moreover, a pair of opposing board part may have a rib for restrict | limiting the insertion amount of the 2nd side edge part with respect to a rod-shaped member, and restrict | limiting rotation of the head of a bolt or a nut. According to such a configuration, it is possible to provide a connector having a rib having two functions of positioning the pair of opposed plate portions and the rod-shaped member and restricting the rotation of the bolt head or nut.
本開示の一態様は、第1側端部の内面及び第2側端部の外面が、凹凸を有していてもよい。このような構成によれば、第1側端部及び第2側端部による棒状部材への連結力を向上させることができる。 In one aspect of the present disclosure, the inner surface of the first side end portion and the outer surface of the second side end portion may have irregularities. According to such a structure, the connection force to the rod-shaped member by the 1st side edge part and the 2nd side edge part can be improved.

一対の対向板部31のそれぞれにおける、X軸に沿って間隔保持部32を挟んだ両側のうちC状端部311の側には、貫通孔313が設けられている。貫通孔313は、後述するボルト4の軸部42を挿通するための真円状の孔である。 A through hole 313 is provided on the side of the C-shaped end portion 311 among both sides of the pair of opposing plate portions 31 that sandwich the interval holding portion 32 along the X axis. The through hole 313 is a perfect circular hole for inserting a shaft portion 42 of the bolt 4 described later.
ボルト4及びナット5は、一対の対向板部31を付勢する付勢機構である。ボルト4は、頭部41及び軸部42を備える。頭部41は、軸方向から見た外形が円形状であって、上面に六角形状の凹部が設けられている。当該凹部は、六角レンチ等の工具を挿入可能に構成されている。ナット5は、軸方向から見た外形が多角形状、本実施形態では六角形状であって、軸部42と螺合可能である。一対の対向板部31に設けられた2つの貫通孔313のそれぞれは、形状及び大きさが同一であり、頭部41及びナット5が通らない大きさに設計されている。軸部42は、貫通孔313に挿通される。貫通孔313に挿通された軸部42にナット5が締結されることによって、ボルト4及びナット5は、一対の対向板部31における間隔保持部32よりもC状端部311寄りの部分を互いに近づける向きの外力を、一対の対向板部31に加える。なお、図2及び図5では、説明の便宜状ボルト4及びナット5を断面図ではなく側面図で示す。 The bolt 4 and the nut 5 are biasing mechanisms that bias the pair of opposed plate portions 31. The bolt 4 includes a head portion 41 and a shaft portion 42. The head 41 has a circular outer shape when viewed from the axial direction, and is provided with a hexagonal recess on the upper surface. The concave portion is configured such that a tool such as a hexagon wrench can be inserted. The outer shape of the nut 5 viewed from the axial direction is a polygonal shape, which is a hexagonal shape in this embodiment, and can be screwed into the shaft portion 42. Each of the two through holes 313 provided in the pair of opposed plate portions 31 has the same shape and size, and is designed to have a size that the head 41 and the nut 5 do not pass. The shaft portion 42 is inserted through the through hole 313. When the nut 5 is fastened to the shaft portion 42 inserted through the through-hole 313, the bolt 4 and the nut 5 have portions closer to the C-shaped end portion 311 than the interval holding portion 32 in the pair of opposing plate portions 31. An external force in the direction of approaching is applied to the pair of opposed plate portions 31. In FIGS. 2 and 5, the expedient bolt 4 and the nut 5 are shown in a side view, not a sectional view.
一対の対向板部31のそれぞれは、リブ314を1つずつ有する。図4に示すように、リブ314は、Z軸方向に沿って設けられている。リブ314は、図5に示すように、X軸方向に沿って、間隔保持部32よりもC状端部311側であって、C状端部311におけるリブ314と対向する外面までの距離がナット5の二面幅分離れた場所に位置する。つまり、ボルト4及びナット5が螺合することによって一対の対向板部31を付勢する際に、ナット5の対応する2面のうち、一方の面がC状端部311におけるリブ314と対向する外面と近接して対向するように位置する。そして、他方の面が、リブ314におけるC状端部311側の面と近接して対向するように位置する。さらに、リブ314におけるI状端部312側の面は、パイプ2にI状端部312が挿入された際、パイプ2の端面と当接するように構成されている。つまり、リブ314は、パイプ2に対するI状端部312の挿入量を規制する位置決めの機能及びナット5の回転を規制する機能を有する。 Each of the pair of opposed plate portions 31 has one rib 314. As shown in FIG. 4, the rib 314 is provided along the Z-axis direction. As shown in FIG. 5, the rib 314 is closer to the C-shaped end 311 side than the interval holding portion 32 along the X-axis direction, and the distance from the C-shaped end 311 to the outer surface facing the rib 314 is The nut 5 is located at a location where the two surface widths are separated. That is, when the pair of opposing plate portions 31 is biased by screwing the bolt 4 and the nut 5, one of the two corresponding surfaces of the nut 5 faces the rib 314 in the C-shaped end portion 311. It is located in close proximity to the outer surface. The other surface is positioned so as to face and face the surface on the C-shaped end portion 311 side of the rib 314. Further, the surface on the I-shaped end 312 side of the rib 314 is configured to contact the end surface of the pipe 2 when the I-shaped end 312 is inserted into the pipe 2. That is, the rib 314 has a positioning function that restricts the amount of insertion of the I-shaped end 312 with respect to the pipe 2 and a function that restricts the rotation of the nut 5.
C状端部311の内面は、当接部315を有し、I状端部312の外面は、当接部316を有する。当接部315及び当接部316は、X軸方向に沿って凸凹状、本実施形態では波状の形状、の表面の部分である。当接部315は、C状端部311がパイプ1に固定される際、パイプ1の外面と当接する。当接部316は、I状端部312がパイプ2に固定される際、パイプ2の突条12と当接する。当接部315及び当接部316は、C状端部311のパイプ1への固定及びI状端部312のパイプ2への固定において滑り止めの機能を有する。 The inner surface of the C-shaped end portion 311 has a contact portion 315, and the outer surface of the I-shaped end portion 312 has a contact portion 316. The abutting portion 315 and the abutting portion 316 are surface portions that are convex and concave along the X-axis direction, that is, a wavy shape in this embodiment. The contact portion 315 contacts the outer surface of the pipe 1 when the C-shaped end portion 311 is fixed to the pipe 1. The abutting portion 316 abuts on the protrusion 12 of the pipe 2 when the I-shaped end portion 312 is fixed to the pipe 2. The contact portion 315 and the contact portion 316 have a function of preventing slipping in fixing the C-shaped end portion 311 to the pipe 1 and fixing the I-shaped end portion 312 to the pipe 2.
次に、コネクタ本体3の製造方法について説明する。まず、アルミニウム又はアルミニウム合金を押出成形することにより、貫通孔313が設けられる前のコネクタ本体3である押出形材が成形される。その後、押出形材に貫通孔313が空けられることによって、コネクタ本体3が成形される。 Next, a method for manufacturing the connector body 3 will be described. First, the extruded shape which is the connector main body 3 before the through hole 313 is provided is formed by extruding aluminum or an aluminum alloy. Then, the connector main body 3 is shape | molded by making the through-hole 313 open in an extrusion shape material.
次に、コネクタ10の使用方法について説明する。まず、パイプ1における4つの溝11のうちの互いに隣り合う2つの溝11にC状端部311が挿入され、パイプ2の端部にI状端部312が挿入されるように、コネクタ本体3によりパイプ1及びパイプ2の連結位置が仮決めされる。この状態で、ボルト4の軸部42が2つの貫通孔313に挿通され、軸部42の先端からナット5が締め付けられる。そうすると、図6に示すように、一対の対向板部31には、C状端部311のそれぞれが互いに近づく向きの外力が加えられる。また、これと同時に、間隔保持部32の作用により、I状端部312のそれぞれが互いに離れる向きの外力が加えられる。これにより、C状端部311は、隣り合う2つの溝11に挿入されてパイプ1の外面を挟んだ状態で、パイプ1の外面に圧接する。また、I状端部312は、パイプ2の内面に挿入された状態で、パイプ2の内面に圧接する。その結果、C状端部311はパイプ1に固定され、I状端部312は、パイプ2に固定される。このようにして、パイプ1及びパイプ2がコネクタ10によってT字状に連結され、パイプアセンブリ100が構成される。 Next, a method for using the connector 10 will be described. First, the connector main body 3 so that the C-shaped end 311 is inserted into two adjacent grooves 11 of the four grooves 11 in the pipe 1 and the I-shaped end 312 is inserted into the end of the pipe 2. Thus, the connection position of the pipe 1 and the pipe 2 is provisionally determined. In this state, the shaft portion 42 of the bolt 4 is inserted into the two through holes 313, and the nut 5 is tightened from the tip of the shaft portion 42. Then, as shown in FIG. 6, an external force is applied to the pair of opposed plate portions 31 in such a direction that the C-shaped end portions 311 approach each other. At the same time, an external force is applied in such a direction that the I-shaped end portions 312 are separated from each other by the action of the interval holding portion 32. Accordingly, the C-shaped end portion 311 is pressed into the outer surface of the pipe 1 while being inserted into the two adjacent grooves 11 and sandwiching the outer surface of the pipe 1. Further, the I-shaped end 312 is in pressure contact with the inner surface of the pipe 2 while being inserted into the inner surface of the pipe 2. As a result, the C-shaped end 311 is fixed to the pipe 1 and the I-shaped end 312 is fixed to the pipe 2. In this way, the pipe 1 and the pipe 2 are connected in a T shape by the connector 10, and the pipe assembly 100 is configured.
[2.効果]
以上詳述した実施形態によれば、以下の効果が得られる。
(1a)貫通孔313に挿通されたボルト4の軸部42にナット5が締結されると、一対の対向板部31には、C状端部311のそれぞれが互いに近づく向きの外力が加えられる。これと同時に、間隔保持部32の作用により、I状端部312のそれぞれが互いに離れる向きの外力が加えられる。これにより、C状端部311は、隣り合う2つの溝11に挿入されてパイプ1の外面を挟んだ状態で、パイプ1の外面に圧接する。また、I状端部312は、パイプ2の内面に挿入された状態で、パイプ2の内面に圧接する。このような作用が、Z軸方向から見た形状が概略H字形状の単一の部品であるコネクタ本体3と、ボルト4及びナット5とによって実現される。したがって、簡素かつ軽量な構成のコネクタ10を提供することができる。
[2. effect]
According to the embodiment detailed above, the following effects can be obtained.
(1a) When the nut 5 is fastened to the shaft portion 42 of the bolt 4 inserted through the through-hole 313, an external force is applied to the pair of opposed plate portions 31 so that the C-shaped end portions 311 approach each other. . At the same time, an external force is applied in the direction in which the I-shaped end portions 312 are separated from each other by the action of the interval holding portion 32. Accordingly, the C-shaped end portion 311 is pressed into the outer surface of the pipe 1 while being inserted into the two adjacent grooves 11 and sandwiching the outer surface of the pipe 1. Further, the I-shaped end 312 is in pressure contact with the inner surface of the pipe 2 while being inserted into the inner surface of the pipe 2. Such an action is realized by the connector main body 3, the bolt 4 and the nut 5, which are a single component having a substantially H-shape when viewed from the Z-axis direction. Therefore, the connector 10 having a simple and lightweight configuration can be provided.
(1b)間隔保持部32は、Z軸方向に沿った交線で一対の対向板部31のそれぞれの対向面310と交わる板状である。このため、ボルト4及びナット5による外力が一対の対向板部31に加えられることにより、一対の対向板部31がZ軸を回転軸とするかのような態様で変形しやすくなる。したがって、一対の対向板部31の変形態様を安定させることができる。 (1b) The space | interval holding | maintenance part 32 is plate shape which cross | intersects each opposing surface 310 of a pair of opposing board part 31 by the intersection line along a Z-axis direction. For this reason, when the external force by the volt | bolt 4 and the nut 5 is applied to a pair of opposing board part 31, it becomes easy to deform | transform a pair of opposing board part 31 in the aspect as if a Z axis | shaft is made into a rotating shaft. Therefore, the deformation | transformation aspect of a pair of opposing board part 31 can be stabilized.
(1c)C状端部311は、パイプ1の4つの溝11のうちの互いに隣り合う2つの溝11に挿入されてパイプ1の外面を挟んだ状態で、パイプ1の外面に圧接することで、パイプ1に固定されるように構成されている。また、I状端部312は、パイプ2の端部に挿入された状態で4つの突条22に圧接することでパイプ2に固定されるように構成されている。このため、コネクタ本体3の形状を簡素かつ小型にすることができる。特に、I状端部312については、平板状という簡素な構成であっても、4つの突条22によって、パイプ2の内面の端部に圧接することができる。すなわち、例えば、円筒状のパイプの内面が突条を有しない場合、I状端部312ではパイプの内面との接触面積が小さく、連結力が不足することが懸念される。このため、コネクタ本体の端部をパイプの内面に沿った形状、つまり半円状にするなどの対応が必要となる。これに対し、本実施形態におけるパイプ2は、4つの突条22と2つの平板状であるI状端部312とが圧接する。具体的には、I状端部312のうち一方の平板部が4つの突条22のうちの2つの突条22と圧接し、他方の板部が残りの2つの突条22と圧接する。したがって、I状端部312を複雑な形状にする必要がなく、簡素かつ軽量な構成でありながら連結力の強いコネクタ10を提供することができる。特に、各突条22の両側に薄肉部22Aが設けられているため、I状端部312とパイプ2とを干渉しにくくすることができる。 (1c) The C-shaped end portion 311 is inserted into two adjacent grooves 11 out of the four grooves 11 of the pipe 1 and presses against the outer surface of the pipe 1 while sandwiching the outer surface of the pipe 1. It is configured to be fixed to the pipe 1. The I-shaped end 312 is configured to be fixed to the pipe 2 by being pressed against the four protrusions 22 while being inserted into the end of the pipe 2. For this reason, the shape of the connector main body 3 can be made simple and small. In particular, the I-shaped end portion 312 can be pressed against the end portion of the inner surface of the pipe 2 by the four protrusions 22 even with a simple configuration of a flat plate shape. That is, for example, when the inner surface of the cylindrical pipe has no protrusions, the I-shaped end portion 312 has a small contact area with the inner surface of the pipe, and there is a concern that the coupling force is insufficient. For this reason, it is necessary to cope with the shape of the end of the connector main body along the inner surface of the pipe, that is, a semicircular shape. On the other hand, in the pipe 2 in the present embodiment, the four protrusions 22 and the two flat plate-like I-shaped end portions 312 are in pressure contact. Specifically, one flat plate portion of the I-shaped end portion 312 is in pressure contact with two of the four protrusions 22, and the other plate portion is in pressure contact with the remaining two protrusions 22. Therefore, it is not necessary to make the I-shaped end portion 312 into a complicated shape, and the connector 10 having a strong coupling force can be provided while having a simple and lightweight configuration. In particular, since the thin portions 22A are provided on both sides of each protrusion 22, it is possible to make it difficult for the I-shaped end portion 312 and the pipe 2 to interfere with each other.
(1d)Y軸方向に沿った間隔保持部32の両側の端部が、一対の対向板部31のそれぞれの対向面におけるX軸方向に沿った中央部に接続されている。また、一対の対向板部31及び間隔保持部32が、単一の部品であるコネクタ本体3として構成されている。このため、C状端部311がパイプ1の外面を圧接する力とI状端部312がパイプ2の内面に圧接する力との偏りが生じにくくすることができる。また、一対の対向板部31及び間隔保持部32が互いに独立した部品として構成される場合と比較して、部品点数が削減できるだけでなく、作業性が向上する。その結果、より簡素な構成のコネクタ10を提供することができる。 (1d) The end portions on both sides of the interval holding portion 32 along the Y-axis direction are connected to the center portion along the X-axis direction on each facing surface of the pair of opposed plate portions 31. Moreover, a pair of opposing board part 31 and the space | interval holding | maintenance part 32 are comprised as the connector main body 3 which is a single component. For this reason, the bias between the force with which the C-shaped end portion 311 presses against the outer surface of the pipe 1 and the force with which the I-shaped end portion 312 presses against the inner surface of the pipe 2 can be made difficult to occur. Moreover, compared with the case where a pair of opposing board part 31 and the space | interval holding | maintenance part 32 are comprised as a mutually independent component, not only a number of parts can be reduced but workability | operativity improves. As a result, the connector 10 having a simpler configuration can be provided.
(1e)コネクタ本体3のZ軸方向に垂直な断面形状は、貫通孔313の部分を除いて一定である。このため、押出形材に貫通孔313を空けるという簡易な方法によって、コネクタ本体3を成形することができる。 (1e) The cross-sectional shape perpendicular to the Z-axis direction of the connector body 3 is constant except for the through-hole 313 portion. For this reason, the connector main body 3 can be shape | molded by the simple method of opening the through-hole 313 in an extrusion shape material.
(1f)間隔保持部32の板厚は、一対の対向板部31のそれぞれの板厚よりも薄い。このため、ボルト4及びナット5による外力が一対の対向板部31に加えられることにより、C状端部311及びI状端部312を共に変位しやすくすることができる。すなわち、間隔保持部の板厚が一対の対向板部のそれぞれの板厚よりも厚い構成とした場合、C状端部を互いに近づける向きの外力が加えられた際に、一対の対向板部自体が変形しやすくなる。この場合、I状端部が互いに離れる向きの外力が不足してしまう。これに対し、本実施形態では、間隔保持部32の板厚は、一対の対向板部31のそれぞれの板厚よりも薄いため、一対の対向板部31自体の変形が抑制され、C状端部311及びI状端部312を共に変位しやすくすることができる。 (1f) The plate | board thickness of the space | interval holding | maintenance part 32 is thinner than each plate | board thickness of a pair of opposing board part 31. FIG. For this reason, when the external force by the volt | bolt 4 and the nut 5 is applied to a pair of opposing board part 31, both the C-shaped edge part 311 and the I-shaped edge part 312 can be made easy to displace. That is, when the plate thickness of the interval holding portion is thicker than the thickness of each of the pair of opposed plate portions, when an external force is applied to bring the C-shaped end portions closer to each other, the pair of opposed plate portions themselves Becomes easier to deform. In this case, the external force in the direction in which the I-shaped end portions are separated from each other is insufficient. On the other hand, in this embodiment, since the plate | board thickness of the space | interval holding | maintenance part 32 is thinner than each plate | board thickness of a pair of opposing board part 31, a deformation | transformation of a pair of opposing board part 31 itself is suppressed, and a C-shaped end Both the part 311 and the I-shaped end 312 can be easily displaced.
(1g)ナット5の対応する2面のうち、一方の面がC状端部311におけるリブ314と対向する外面と、他方の面がリブ314におけるC状端部311側の面と、近接して対向するように位置する。つまり、ナット5の対応する2面が、C状端部311及びリブ314に挟まれるように位置し、ナット5の回転が規制される。また、リブ314におけるI状端部312側の面は、パイプ2にI状端部312が挿入された際、パイプ2の端面と当接するように構成されている。このため、パイプ2に対するI状端部312の挿入量を規制する位置決めの機能及びナット5の回転を規制する機能をリブ314に持たせることができる。 (1g) Of the two corresponding surfaces of the nut 5, one surface is close to the outer surface facing the rib 314 in the C-shaped end portion 311 and the other surface is close to the surface on the C-shaped end portion 311 side of the rib 314. Positioned so as to face each other. That is, two corresponding surfaces of the nut 5 are positioned so as to be sandwiched between the C-shaped end portion 311 and the rib 314, and the rotation of the nut 5 is restricted. Further, the surface of the rib 314 on the I-shaped end portion 312 side is configured to contact the end surface of the pipe 2 when the I-shaped end portion 312 is inserted into the pipe 2. For this reason, the rib 314 can be provided with a positioning function that restricts the amount of insertion of the I-shaped end 312 into the pipe 2 and a function that restricts the rotation of the nut 5.
(1h)C状端部311の内面及びI状端部312の外面は、X軸方向に沿って波状の形状である当接部315及び当接部316を有する。このため、当接部315及び当接部316に、C状端部311のパイプ1への固定及びI状端部312のパイプ2への固定において滑り止めの機能を持たせることができる。 (1h) The inner surface of the C-shaped end portion 311 and the outer surface of the I-shaped end portion 312 have a contact portion 315 and a contact portion 316 that have a wave shape along the X-axis direction. For this reason, the abutting portion 315 and the abutting portion 316 can have a function of preventing slipping in fixing the C-shaped end portion 311 to the pipe 1 and fixing the I-shaped end portion 312 to the pipe 2.
なお、本実施形態では、パイプ1が第1の棒状部材の一例に相当し、パイプ2が第2の棒状部材の一例に相当する。また、ボルト4及びナット5が付勢機構の一例に相当し、C状端部311が第1側端部の一例に相当し、I状端部312が第2側端部の一例に相当する。また、X軸方向が第1の方向の一例に相当し、Y軸方向が第2の方向の一例に相当し、Z軸方向が第3の方向の一例に相当する。 In the present embodiment, the pipe 1 corresponds to an example of a first bar member, and the pipe 2 corresponds to an example of a second bar member. The bolt 4 and the nut 5 correspond to an example of an urging mechanism, the C-shaped end 311 corresponds to an example of a first side end, and the I-shaped end 312 corresponds to an example of a second side end. . The X-axis direction corresponds to an example of the first direction, the Y-axis direction corresponds to an example of the second direction, and the Z-axis direction corresponds to an example of the third direction.

以上、本開示の実施形態について説明したが、本開示は、上記実施形態に限定されることなく、種々の形態を採り得ることは言うまでもない。
[3. Other Embodiments]
As mentioned above, although embodiment of this indication was described, it cannot be overemphasized that this indication can take various forms, without being limited to the above-mentioned embodiment.
(2a)上記実施形態では、溝11及び突条12を有するパイプ1及び溝21及び突条22を有するパイプ2がコネクタ10によって連結されたパイプアセンブリ100を例示した。しかし、パイプアセンブリの構成はこれに限定されるものではない。 (2a) In the above embodiment, the pipe assembly 100 in which the pipe 1 having the groove 11 and the protrusion 12 and the pipe 2 having the groove 21 and the protrusion 22 are connected by the connector 10 is illustrated. However, the configuration of the pipe assembly is not limited to this.
例えば、図7に示す変形例のパイプアセンブリ200は、上記実施形態のパイプ1、パイプ2及びコネクタ10に代えて、パイプ6、パイプ7及びコネクタ20を有する。
パイプ6及びパイプ7は、パイプ1及びパイプ2と同様、アルミニウム製又はアルミニウム合金製のパイプである。ただし、パイプ6及びパイプ7は、パイプ1及びパイプ2と比較すると、溝及び突条を有しない円筒状のパイプである点が異なる。
For example, the pipe assembly 200 of the modified example shown in FIG. 7 has a pipe 6, a pipe 7 and a connector 20 instead of the pipe 1, the pipe 2 and the connector 10 of the above embodiment.
The pipe 6 and the pipe 7 are pipes made of aluminum or aluminum alloy like the pipes 1 and 2. However, the pipe 6 and the pipe 7 are different from the pipe 1 and the pipe 2 in that the pipe 6 and the pipe 7 are cylindrical pipes having no grooves and protrusions.
コネクタ20は、パイプ6の外面とパイプ7の端部とを連結するための部品である。コネクタ20は、上記実施形態のコネクタ10と比較すると、コネクタ本体3に変えて、コネクタ本体8を有する点が異なる。 The connector 20 is a component for connecting the outer surface of the pipe 6 and the end of the pipe 7. The connector 20 is different from the connector 10 of the above embodiment in that the connector 20 has a connector body 8 instead of the connector body 3.
コネクタ本体8は、基本的な構成はコネクタ本体3と同様である。すなわち、コネクタ本体8は、アルミニウム製又はアルミニウム合金製の部品であって、Z軸方向から見た形状が概略H字形状の単一の部品である。コネクタ本体8のZ軸方向に垂直な断面形状は、後述する貫通孔813の部分を除いて一定である。コネクタ本体8は、一対の対向板部81と、間隔保持部82と、を有する。 The basic structure of the connector body 8 is the same as that of the connector body 3. That is, the connector main body 8 is a component made of aluminum or aluminum alloy, and the shape viewed from the Z-axis direction is a single component having a substantially H shape. The cross-sectional shape perpendicular to the Z-axis direction of the connector body 8 is constant except for a through-hole 813 described later. The connector main body 8 has a pair of opposing plate portions 81 and a spacing holding portion 82.
一対の対向板部81のそれぞれは、Z軸方向から見た板厚が概略一定である板状の部分であって、互いに間隔を空けて対向する対向面810を有する。X軸方向に沿った一対の対向板部81の両側の端部であるC状端部811及びI状端部812のうち、C状端部811は、上記実施形態のC状端部311と比較すると、Z軸方向から見てパイプ6の外径とほぼ同じ径の円弧状の内面を有する点が異なる。C状端部811は、パイプ6の外面を囲んだ状態でパイプ6の外面に圧接することで、パイプ6に固定されるように構成されている。I状端部812は、上記実施形態のI状端部312と同様、一対の対向板部81のそれぞれが互いに間隔を空けて配置されたI状の、つまり平板状の端部である。ただし、I状端部812は、I状端部312と比較すると、対向面810同士の間隔が広く、Z軸方向に沿った幅が狭い点が異なる。I状端部812は、パイプ7の端部に挿入された状態でパイプ7の内面に圧接することで、パイプ7に固定されるように構成されている。 Each of the pair of opposed plate portions 81 is a plate-like portion having a substantially constant plate thickness when viewed from the Z-axis direction, and has opposed surfaces 810 that are opposed to each other with a space therebetween. Of the C-shaped end portion 811 and the I-shaped end portion 812 that are the end portions on both sides of the pair of opposing plate portions 81 along the X-axis direction, the C-shaped end portion 811 is the same as the C-shaped end portion 311 of the above embodiment. In comparison, the difference is that it has an arc-shaped inner surface having substantially the same diameter as the outer diameter of the pipe 6 as viewed from the Z-axis direction. The C-shaped end portion 811 is configured to be fixed to the pipe 6 by being pressed against the outer surface of the pipe 6 while surrounding the outer surface of the pipe 6. The I-shaped end portion 812 is an I-shaped, that is, a flat plate-shaped end portion in which each of the pair of opposed plate portions 81 is spaced from each other, like the I-shaped end portion 312 of the above embodiment. However, the I-shaped end portion 812 is different from the I-shaped end portion 312 in that the distance between the facing surfaces 810 is wide and the width along the Z-axis direction is narrow. The I-shaped end 812 is configured to be fixed to the pipe 7 by being pressed against the inner surface of the pipe 7 while being inserted into the end of the pipe 7.
