Description
本発明は、吊り線に沿ってケーブルを電柱間に架設する際に用いる螺旋状ケーブル支持具の連結具に関するものである。 The present invention relates to a connector for a helical cable support used when a cable is installed between utility poles along a suspension line.
互いに連結する螺旋状ケーブル支持具の端末に基部片において止着する、第一、第二の連結材で成り、第一連結材の基部片に二股分岐状の嵌挿片を突設し、該嵌挿片を嵌挿する筒状片を第二連結材の前記基部片に連設し、該筒状片には前記嵌挿片に設けた係止爪を受止する窓口を設けた構造のものがある(例えば、特許文献1)。 It consists of first and second connecting members that fasten at the base piece to the ends of the helical cable supports that are connected to each other, and a bifurcated branch-insertion piece projects from the base piece of the first connecting member, A cylindrical piece for inserting the insertion piece is connected to the base piece of the second connecting member, and the cylindrical piece is provided with a window for receiving a locking claw provided on the insertion piece. There is a thing (for example, patent document 1).
前記従来例は、第二連結材の筒状片に第一連結材の嵌挿片を、その弾性を利用して強制的に嵌挿して両連結材を互いに連結するものであるが、その連結状態を筒状片内に弾性を利用して嵌挿した嵌挿片の先端間に筒状片の内腔部奥壁に設けた空子を介在させて嵌挿片の弾性変形を規制するようにしてその連結状態を維持し、両連結材が容易に分離できない構造にしてある。 In the above-mentioned conventional example, the connecting piece is forcibly inserted into the cylindrical piece of the second connecting material by forcibly inserting the connecting piece of the first connecting material using its elasticity. The elastic deformation of the insertion piece is regulated by interposing a void provided on the inner wall of the cylindrical piece between the tips of the insertion piece inserted into the cylindrical piece using elasticity. Thus, the connection state is maintained and the two connection members cannot be easily separated.
要するに、従来の連結具は、両連結材を一旦連結(接続)すると、分離することが難しく、再利用ができず、経済性に欠けていた。 In short, the conventional coupler is difficult to separate once the two coupling members are coupled (connected), cannot be reused, and lacks economic efficiency.
本発明は、再利用のできる連結具(螺旋状支持具の)を提供すべく創案したものである。 The present invention was devised to provide a reusable connector (for a helical support).
互いに連結する螺旋状ケーブル支持具の端末に基部片において止着する、第一、第二の連結材で構成し、第一連結材の前記基部片に、尻上り状の傾斜面を備えた嵌挿片を突設し、該嵌挿片の前記傾斜面に貫通孔を設けると共に、第二連結材の前記基部片に筒状片を連設し、該筒状片の、前記嵌挿片を嵌挿する内腔部の奥壁に凹入部を設け、該凹入部に嵌挿片の前記先端側が一致して嵌合したときの前記貫通孔位置に当位する、一対の透孔を前記筒状片の周側に前記内腔部を介して相対設し、該一方の透孔に先端を係合して他の一方の透孔に貫通させた接続杆部と該接続杆部に連設した基杆部とで成る接続杆の弾性の基杆部の基部を前記第二連結材の周側に止着し、該基杆部の中間部に摘み兼用の張出し部片を設け該張出し部片の一側と前記第二連結材との間に前記基杆部の弾性付勢に抗してそれぞれ介在する尻上り状の傾斜面を備えた先部片を備えた、一対の操作杆を第一連結材側の前記基部片に、接続杆の前記基杆部の係合間隙を介して突設し、該操作杆の前記先部片を前記嵌挿片の先端と前記貫通孔の軸線方向に部分的に重ね合わせた、構成とするのである。 The first and second connecting members are fastened to the ends of the helical cable supports that are connected to each other at the base piece, and the base piece of the first connecting member is provided with an upsloped inclined surface. An insertion piece is protruded, a through hole is provided in the inclined surface of the fitting insertion piece, a cylindrical piece is connected to the base piece of the second connecting member, and the fitting insertion piece of the cylindrical piece is A recessed portion is provided in the inner wall of the inner cavity portion to be inserted, and a pair of through-holes positioned at the through hole position when the distal end side of the inserting insertion piece is fitted and fitted to the recessed portion is formed in the cylinder. A connecting hook part which is provided relative to the peripheral side of the shaped piece through the lumen part, engages the tip of the one through hole and penetrates the other through hole, and is connected to the connecting hook part The base portion of the elastic base portion of the connecting rod composed of the base portion is fastened to the peripheral side of the second connecting member, and a projecting portion piece serving as a knob is provided in the middle portion of the base portion. One side of the piece and the first A pair of operating rods having a tip piece with an upsloped inclined surface interposed between the connecting members against the elastic urging of the base portion, and a base portion on the first connecting material side. A piece is protruded through an engagement gap of the base portion of the connection rod, and the tip piece of the operation rod is partially overlapped with the tip of the fitting insertion piece and the axial direction of the through hole. The configuration.
本発明によれば、第一連結材側の嵌挿片を第二連結材側の筒状片内腔部に位置合わせして嵌挿することにより、簡単かつ確実に連結することができる。 According to this invention, it can connect simply and reliably by aligning and inserting the fitting piece by the side of a 1st connection material in the cylindrical piece lumen | bore part by the side of a 2nd connection material.
そして、指先等で接続杆の弾性を利用して第一連結材側の貫通孔と第二連結材側の透孔から接続杆部を離脱させることにより、第一、第二連結材を互いに自由状態に容易にすることができ、従って、連結状態からの分離操作を支障なく行え、再利用のできる連結具を提供できる。 Then, by using the elasticity of the connecting rod at the fingertip or the like, the first and second connecting members are free from each other by separating the connecting flange portion from the through hole on the first connecting member side and the through hole on the second connecting member side. Therefore, it is possible to provide a connector that can be separated from the connected state without any trouble and can be reused.

本発明に係る、螺旋状ケーブル支持具の連結具Aは、互いに連結する螺旋状ケーブル支持具a,aの端末に、該端末を嵌着して取付けた第一、第二の連結材1,2を分離自在に接続して前記支持具a,aを連結するために用いるものである。
The connector A of the spiral cable support according to the present invention includes a first and a second connecting
この連結具Aを構成する第一連結材(合成樹脂を素材とする)1は、支持具aの端末を嵌挿して止着する筒状の基部片3の先端面に、尻上り状の傾斜面4a´を設けて断面三角形(厳密な意味での三角形である必要はない)とした先端部4aを備えた嵌挿片4を突設し、該嵌挿片4の前記傾斜面4a´の中間部には貫通孔12を設けると共に、この嵌挿片4の周側の短い部分側の一側に基部を前記基部片3に固着した、一対の操作杆5,5を平行させて突設して構成したものである。
A first connecting material (made of synthetic resin) 1 constituting the connecting tool A is inclined upward on the tip surface of a
操作杆5は、断面方形の棒杆体の先端に外表面を尻上り状の傾斜面5´aとした尖頭直角三角形状の先部片5a(要するに、後記する機能の有る傾斜面を備えたものであれば良い)を備え、該先部片5a側の表面部分は凹入部5bを設けて成り、第二連結材2に設けた接続杆6の係合間隙7を存して前記の通り互いに平行させて基部を一体にして前記基部片3に突設したものである。
The operation rod 5 is provided with a pointed right triangular tip portion 5a (in other words, an inclined surface having the functions described later) having an outer surface as an inclined surface 5'a at the top of the rod rod body having a square cross section. The surface portion on the side of the tip piece 5a is provided with a recessed portion 5b, and there is an engagement gap 7 of the connecting
この操作杆5の先部片5aは、嵌挿片4の前記尻上り状の傾斜面4a´を備えた先端部4aに対して後部側が前記貫通孔12の軸線方向に重なる(嵌挿片4の径方向に)位置に位置し、該先部片5aの傾斜面5a´を利用して接続杆6の基杆部6bを屈曲変形(ばね変形)させて接続杆部6aの先端を第二連結材2側に設けた透孔13より離脱させたとき、嵌挿片4の先端部4a(先端)は、該透孔13の口縁位置(隣接位置)に存し、先部片5aの第二連結材2の基部片基端方向への移動(前進)に伴う前記傾斜面5a´による前記離脱状態の継続によって、該先端部4aは接続杆部6aと前記透孔13の間に介在して、先部片5a(の前進)による接続杆6の基杆部6bに対する屈曲変形作用が終了した際にも接続杆部6aと重なり合って、該接続杆部6aの先端の前記透孔13への係合を規制するようにしてある。
The front piece 5a of the operation rod 5 has a rear side that is overlapped in the axial direction of the through-

In addition, when the through-
連結具Aを構成する第二連結材2は、第一連結材1と同様に支持具aの端末を嵌挿して止着する筒状の基部片8の先端に筒状片9を連設して構成したものである。
The second connecting
筒状片9は第一連結材1側の前記嵌挿片4の断面形状(各部の位置決めと連結材1,2同士の廻り止めにすることができるので非円形が望ましい、実施例は長丸形)と一致させて嵌挿する内腔部10を備え、該内腔部10の奥壁10aに嵌挿片4の前記先端部4a部分が一致して嵌合する断面三角形状の凹入部11を設け、該凹入部11に嵌挿片4の先端部4aを一致して嵌合させたときの前記貫通孔12位置に当位するようにして前記透孔13とこれに相対する透孔13´を前記筒状片9の周側に設けてある。
The cylindrical piece 9 has a cross-sectional shape of the fitting insertion piece 4 on the first connecting
透孔13,13´は、筒状片9の周側基部すなわち前記内腔部10の奥壁10aの隣接位置に配するのが望ましく、この位置関係(奥壁10aの存在)により嵌挿片先端部4aの傾斜面4a´にばね付勢に抗して(図1の図面上、上方へ)押圧される接続杆6(の接続杆部6a)はその変形を規制され、貫通孔12に対する係合(嵌挿)が円滑に行われる。
The through-
接続杆6は、前記基杆部6bと該基杆部6bの先端に直角方向にして連設した前記接続杆部6aとで成り、接続杆部6aの先端を前記一方の透孔13´を通じて他の一方の透孔13に係合し、一方の透孔13´から導出した基杆部6bを第二連結材2の長手(軸線)方向に沿わせて配し、その基部を第二連結材2の基部片8の周側に止着し、基杆部6bの中間部に張出し部片14を設けて構成したものである。
The
この接続杆6は、嵌挿片4を内腔部10(筒状片9)に嵌挿したとき、すなわち、第一、第二の連結材1,2を互いに連結したとき、基杆部6bが第一連結材1に突設した一対の操作杆5,5間の係合間隙7内に係合し、基杆部6bに設けた張出し部片14の両側の張出し部は、操作杆5に設けた凹入部5bに係合するようにしてある(接続杆部6aの先端が透孔3´と連通孔12を通じて透孔3に係合し、筒状片9すなわち、内腔部10からの嵌挿片4の離脱を規制し、第一、第二の連結材1,2の連結状態を保持するようにしてあることはいうまでもない)。
When the fitting piece 4 is fitted and inserted into the lumen 10 (cylindrical piece 9), that is, when the first and second connecting
しかして、互いに連結する螺旋状ケーブル支持具a,aの一方の端末に第一連結材1を、他方の端末に第二連結材2を基部片3,8を利用して嵌(止)着し、第一連結材1側の嵌挿片4と第二連結材2側の筒状片9(内腔部10)とを一致させるようにして、第一、第二の連結材1,2を互いに近接する方向に相対的に移動させると、第一連結材1側の操作杆5,5間の係合間隙7に第二連結材2側の接続杆6(基杆部6b)は係合し、かつ、操作杆5の先部片5aが接続杆6の基杆部6bに設けた張出し部片14と基部片8との間に狭入し、先部片5aの移動に伴ってその傾斜面5a´は基杆部6bを弾性変形させて筒状片9から部分的に漸次離開させることになる(図1の図面上、上方に離開させる)。
Thus, the first connecting
この結果、基杆部6bに連設した接続杆部6aの先端は筒状片9周側に設けた透孔13から離脱し、この離脱状態は操作杆先端部4aが張出し部片14に接触中(先端部4aの前記移動の継続中)維持され、該離脱状態継続中に、嵌挿片4の先端部4aの先端が、接続杆部6aと透孔13との間に移動し、ばね付勢による接続杆部6a先端の透孔13への係合を阻止することになる。
As a result, the tip of the connecting rod 6a provided continuously with the base rod 6b is detached from the through
そして、操作杆5の先部片5aが張出し部片14位置より第二連結材2の基部片8側に移動して先部片5aによる張出し部片14の押圧が解かれても、接続杆6の接続杆部6a(の先端)は、嵌挿片4の傾斜面4a´上位置に存し、接続杆部6aの透孔13への係合は阻止される(従って、この状態時には、両連結材1,2は連結状態になく、容易に分離することができる)。
Even if the tip piece 5a of the operation rod 5 moves from the position of the overhanging piece piece 14 to the
さらに、前記相対的移動を継続すると、嵌挿片先端部4a先端は凹入部11内を前進し(嵌挿片4は内腔部10内を前進し)、嵌挿片先端部4aの傾斜面4a´を接続杆部6aは相対的に登り、先端部4aが凹入部11に一致した状態に至ると同時に、接続杆部6aは貫通孔12位置に移動し、該貫通孔12に嵌挿され、該貫通孔12を通じて透孔13に係合して両連結材1,2の連結操作は終了する。
Furthermore, if the relative movement is continued, the tip of the insertion piece tip 4a advances in the recessed portion 11 (the insertion piece 4 advances in the lumen 10), and the inclined surface of the insertion piece tip 4a. At the same time, the connecting flange 6a climbs relative to 4a ', and the tip 4a reaches the state where it coincides with the
この連結状態は、接続杆6の接続杆部6aが貫通孔12を通じて透孔3,3´に係合して筒状片9にわたした状態にあるので、嵌挿片4は筒状片9から分離することがなく、確実に保たれる。
In this connected state, the connecting rod 6 a of the connecting
そして、摘み兼用となる張出し部片14を摘んで、かつ、接続杆6の弾性付勢に抗して接続杆部6aを第二連結材2側の透孔13と第一連結材1側の貫通孔12から離脱させると、透孔13を備えた筒状片9(第二連結材2)と貫通孔12を備えた嵌挿片4(第一連結材1)は互いに自由になり、該離脱状態を維持させた状態で透孔13を貫通孔12を互いにずらせることにより、両連結材1,2は自在に分離することができるのである。
Then, the overhanging piece 14 which is also used as a knob is picked, and the connection rod portion 6a is connected to the through
