Description

【0001】
【発明の属する技術分野】
本発明は、光ファイバケーブル等の接続部或いは余長部を収納するためのケーブルクロージャに関するものである。
【0002】
【従来の技術】
図7及び図8を用いて、従来のケーブルクロージャについて説明する。
【0003】
光ファイバケーブル等の接続部或いは余長部を収納するためのケーブルクロージャCは、前面に開口部1aを有するケース本体1と該ケース本体1の開口部1aを閉塞するケース蓋2とからなり、ケース蓋2の下端部は、ケース本体1の下端部に取着された枢軸3に枢支されている。また、ケース本体1aには、光ファイバケーブル等をケース本体内に導入するケーブル導入口1bが形成されているとともに、ケーブル外被把持金具やテンションメンバー固定金具等が設けられており、更に、ケース本体1aには、支持台4と該支持台4の先端に枢支されたトレイ支持金具5とが設けられており、トレイ支持金具5には、トレイTが多段に取り付けられている。なお、6は、ケース本体1に形成された半円形状凹部1cとケース蓋2に形成された半円形状凹部2aとにより形成されるケーブル導入口である。
【0004】
ケース本体1の上部には、架空用支持金具1dが設けられており、この架空用支持金具1dを利用して、ケース本体1の開口部1aがケース蓋2により閉塞されたケーブルクロージャCを、架設用ワイヤロープWに吊り下げるように構成されている。
【0005】
光ファイバ心線等の接続換え等を行う際には、ケース本体1にケース蓋2を取り付けている適当数の締め付けボルト7を取り外した後、図7に示されているように、枢軸3を中心に、ケース本体1に対して、略90°の位置までケース蓋2を回動させる。次いで、トレイ支持金具5を、ケース本体1に取り付けている止めネジ8を取り外して、図7に実線で示されているトレイTが多段に取り付けられているトレイ支持金具5を、図7に二点鎖線で示されているように、トレイTが略水平になるような位置まで回動させて、光ファイバ心線等の接続換え等を行う。
【0006】
【発明が解決しようとする課題】
上述したように、光ファイバ心線等の接続換え等は、トレイ支持金具5を回動させて、トレイTを略水平位置に維持した状態で行うが、従来のケーブルクロージャにおいては、トレイ支持金具5が、光ファイバ心線等の接続換え等の作業中に、誤って、水平位置から下方に回動するというトラブルが発生するという問題があった。このように、トレイ支持金具5が水平位置から下方に回動すると、トレイTに収容されたファイバ心線等とトレイTから導出されたファイバ心線等に、不必要な力が加わり、ファイバ心線等が損傷することになる。
【0007】
本発明の目的は、上述した従来のケーブルクロージャが有する課題を解決することにある。
【0008】
【課題を解決するための手段】
上記の目的を達成するため、本発明は、先端部に穿設された長溝(40b)の支持ブロック(1e)側近傍の上縁に形成された水平状のストッパー(40c)を有する一対の垂直板状の支持板(40a)と、前記ストッパー(40c)を挟んで前記長溝(40b)と反対側に位置する前記一対の支持板(40a)に取着されたロッド(40e)とを有する支持部材(40)、平板状のトレイ載置部(50a)と、該トレイ載置部(50a)に対して略垂直に延在する側枠(50b)と、該側枠(50b)に対して略垂直に前記トレイ載置部(50a)と反対方向に延在する係止具取付部(50c)と、相対する垂直側部(50f)の先端部に形成された側面形状が略方形状の係止部(50f’)と、該係止部(50f’)に取着されているとともに前記支持板(40a)に穿設された長溝(40b)に挿入される係合ピン(50g)とを有するトレイ取付部材(50)、及び、前記トレイ取付部材(50)を前記支持部材(40)方向に付勢するための前記係合ピン(50g)と前記ロッド(40e)との間に張設された弾性部材(20)とを有し、前記係止部(50f’)の前記ストッパー(40c)側に位置する上部角部(50f”)付近が前記ストッパー(40c)に当接することにより、前記トレイ取付部材(50)と前記支持部材(40)とが略水平状態に維持されるように構成されており、且つ、前記トレイ取付部材(50)を、前記弾性部材(20)の付勢力に抗して前記支持部材(40)から離れる方向に動かして、前記係止部(50f’)と前記ストッパー(40c)との当接を解除することにより、前記トレイ取付部材(50)を上方に回動することができるように構成されており、また、前記側枠(50b)に水平部分(50b’)を延設するとともに、該水平部分(50b’)と前記トレイ載置部(50a)とを蝶番(50h)により連結することにより、前記側枠(50b)が、前記トレイ載置部(50a)に対して回動可能に構成されており、更に、前記トレイ載置部(50a)の下面に結合部材(v1)が取着されているとともに、前記側枠(50b)の水平部分(50b’)の下面には、前記トレイ載置部(50a)の下面に取着された結合部材(v1)に接着可能な結合部材(v2)を取着したものである。
【0009】
【実施例】
以下に、本発明の実施例について説明するが、本発明の趣旨を越えない限り、何ら、本実施例に限定されるものではない。なお、支持台4と該支持台4の先端に枢支されたトレイ支持金具5以外の構成については、上述した従来のケーブルクロージャと実質的に同一であるので、支持台4と該支持台4の先端に枢支されたトレイ支持金具5以外の具体的な構成については、その説明を省略するとともに、同じ符号が使用されている。
【0010】
上述した支持台4に相当する本発明の支持部材40は、ケース本体1の適当な支持ブロック1eに、ネジ10等の適当な固着具により取着された一対の垂直板状の支持板40aを有しており、支持板40aは、水平方向に所定の間隔を置いて配置されている。水平板40aの先端部には、支持板40aの長手方向に沿って、長溝40bが形成されており、また、長溝40bの支持ブロック1e側近傍の上縁には、互いに離反する方向に延在する水平状のストッパー40cが形成されている。更に、ストッパー40cを挟んで、長溝40bと反対側に位置する支持板40aには透孔40dが穿設されており、該透孔40dには、ロッド40eが挿着されている。なお、40fは、長溝40bと反対側の支持板40aの端部に形成された折曲部40gに穿設された、上記のネジ10が挿通されるネジ孔である。
【0011】
50は、上述したトレイ支持金具5に相当する、板材を屈曲することにより形成されるトレイ取付部材であり、トレイ取付部材50は、トレイTが多段に載置される平板状のトレイ載置部50aと、トレイ載置部50aの先端部から、トレイ載置部50aに対して略直角に延在する側枠50bと、該側枠50bの先端部から、側枠50bに対して略直角に、トレイ載置部50aと反対方向に延在する係止具取付部50cと、側枠50bと反対側に位置するトレイ載置部50aの先端部に形成されたトレイ載置部50aと同一面上に延在する幅狭部50dと、幅狭部50dに延設された幅狭部50dより幅の広い略長方形状の連結部50eとを有している。
【0012】
トレイ取付部材50の連結部50eの長手方向両端部には、連結部50eの面に対して略直交するとともに、側枠50bと同じ方向に延在する垂直側部50fが形成されている。垂直側部50fは、連結部50eを越えて外側に延在しており、垂直側部50fの先端部には、側面形状が略方形状の係止部50f’が形成されている。また、係止部50f’の略中央部には、互いに、その先端が接近する方向に延びる係合ピン50gが取着されている。
【0013】
次に、支持部材40とトレイ取付部材50との連結手段について説明する。
【0014】
トレイ取付部材50の係止部50f’に取着された係合ピン50gを、支持部材40の支持板40aに穿設された長溝40bに挿入するとともに、支持部材40の支持板40aに穿設された長溝40bに挿入された係合ピン50gの先端部と、支持部材40の支持板40aに穿設された透孔40dに挿着されたロッド40eとの間に、それぞれ、コイルスプリング20の両端を係止させる。コイルスプリング20により、トレイ取付部材50が、支持部材40方向に付勢されるように構成されており、トレイ取付部材50の係止部50f’に取着された係合ピン50gが、支持部材40の支持板40aに穿設された長溝40bのロッド40e側縁部に当接している。この状態においては、トレイ取付部材50の係止部50f’のストッパー40c側角部50f”付近が、支持部材40のストッパー40cに当接しており、図2及び図3(a)に示されているように、トレイ取付部材50と支持部材40とが略水平状態に維持されており、トレイ取付部材50が下方に回動することが防止されている。
【0015】
トレイ取付部材50と支持部材40とが略水平となっている状態で、トレイ取付部材50に載置されているトレイTに収納されている光ファイバ心線の接続換え等の作業を行う。光ファイバ心線の接続換え等の作業が終了した際には、図3(b)に示されているように、トレイ取付部材50を、コイルスプリング20の付勢力に抗して、支持部材40から離れる方向に、略水平方向に移動させて、トレイ取付部材50の係止部50f’のストッパー40c側角部50f”を、支持部材40のストッパー40cの係合から外し、その後、図3(c)に示されているように、係合ピン50gを中心に、トレイ取付部材50を、支持部材40に対して略直交するまで上方に回動させる。次いで、トレイ取付部材50の係止具取付部50cに穿設された透孔に挿着されている止めネジ8を、ケース本体1に形成されている図示されていないネジ孔に螺合させることにより、図1に示されているように、トレイ取付部材50をケース本体1に取り付ける。その後、ケース本体1の開口部1aをケース蓋2で閉塞し、締め付けボルト7により、ケース本体1にケース蓋2を取り付ける。
【0016】
本発明においては、支持部材40の支持板40aに穿設された長溝40bに挿入された係合ピン50gの先端部と、支持部材40の支持板40aに穿設された透孔40dに挿着されたロッド40eとの間に張設されたコイルスプリング20により、トレイ取付部材50が、支持部材40方向に付勢され、トレイ取付部材50の係止部50f’のストッパー40c側角部50f”付近が、支持部材40のストッパー40cに当接しているので、作業中に不意に、トレイ取付部材50が、支持部材40から離れる方向に移動して、トレイ取付部材50の係止部50f’と支持部材40のストッパー40cとの係合が外れて、トレイ取付部材50が、自重により、係合ピン50gを中心に、下方に回動するようなことが防止できる。
【0017】
なお、上述した実施例においては、締め付けボルト7により、ケース蓋2をケース本体1に取り付ける例や、止めネジ8により、トレイ取付部材50をケース本体1に取り付ける例が示されているが、締め付けボルト7や止めネジ8に限定されることなく、種々の固着手段を適用することができる。また、トレイ取付部材50を、支持部材40方向に付勢するものであれば、コイルスプリング20に限定されることなく、ゴムバンド等の弾性部材を使用することができる。
【0018】
次に、図4〜図6を用いて、本発明のケーブルクロージャの別の実施例について説明するが、この実施例においては、トレイ取付部材50の構成が異なる以外は、上述した実施例と同じであるので、トレイ取付部材50の上記実施例との相違点のみについて、以下に説明する。
【0019】
本実施例においては、側枠50bに、トレイ載置部50aと面一に形成された水平部分50b’を延設するとともに、側枠50bとトレイ載置部50aとを、蝶番50hにより連結し、水平状態のトレイ載置部50aに対して、側枠50bを下方に回動可能に構成したものである。また、トレイ載置部50aの下面には、針状部材が密集した結合部材v1を取着するとともに、該結合部材v1に対応するように、同じく針状部材が密集した結合部材v2を、側枠50bの水平部分50b’の下面に取着して、側枠50bを下方に回動させた際に、側枠50bの結合部材v2を、トレイ載置部50aの結合部材v1に接着させて、側枠50bがふらつかないように構成されている。トレイ取付部材50のトレイ載置部50aに多段に取り付けられたトレイTを略水平状態に維持して、光ファイバ心線等の接続換え等の作業を行う際に、側枠50bが、図4において二点鎖線で示されているように、下方に回動するとともに、結合部材v1、v2により、側枠50bがふらつかないように、側枠50bがトレイ載置部50aに保持されているので、側枠50bが、光ファイバ心線等の接続換え等の作業の邪魔にならない。結合部材v1、v2は、上述した針状部材が密集した部材に限らず、ループ、フックからなるベルクロファスナー等、種々の結合部材を用いることができる。
【0020】
また、本実施例においては、垂直側部50fの係止部50f’のトレイ載置部50a側の上部角部50hが円弧状に形成されている。このように、係止部50f’のトレイ載置部50a側の上部角部50hが円弧状に形成されているので、上述した図3(b)に示されているように、トレイ取付部材50を、コイルスプリング20の付勢力に抗して、支持部材40から離れる方向に、略水平方向に移動させることなく、図6(a)に示されているように、単に、トレイ取付部材50を、係合ピン50gを中心に上方に回動させると、トレイ取付部材50の円弧状に形成された上部角部50hが、支持部材40のストッパー40cのトレイ取付部材50側の先端縁40c’に接触し、案内されながら、ストッパー40cのトレイ取付部材50側の先端縁40c’が、垂直側部50fに形成された凹部50iに入り込むまで、トレイ取付部材50が回動し、その後、更に、トレイ取付部材50を回動させると、図6(c)に示されているように、垂直側部50fに形成された凹部50iに入り込んで垂直側部50fと当接したストッパー40cのトレイ取付部材50側の先端縁40c’を支点として、トレイ取付部材50が、支持部材40に対して略直交するまで上方に回動する。次いで、トレイ取付部材50の係止具取付部50cに穿設された透孔に挿着されている止めネジ8を、ケース本体1に形成されている図示されていないネジ孔に螺合させることにより、図1に示されているように、トレイ取付部材50をケース本体1に取り付ける。その後、ケース本体1の開口部1aをケース蓋2で閉塞し、締め付けボルト7により、ケース本体1にケース蓋2を取り付ける。
【0021】
上述したように、係止部50f’のトレイ載置部50a側の上部角部50hを円弧状に形成することにより、上述した図3(b)に示されているように、トレイ取付部材50を、コイルスプリング20の付勢力に抗して、支持部材40から離れる方向に、略水平方向に移動させることなく、単に、トレイ取付部材50を、係合ピン50gを中心に上方に回動させることにより、トレイ取付部材50を、水平状態から、支持部材40に対して略直交するまで上方に回動することができる。
【0022】
上述した2つの実施例においては、トレイ取付部材50を、水平状態から支持部材40に対して上方に回動させる例を説明したが、図3(b)及び図6(b)に示されているトレイ取付部材50の水平状態から、トレイ取付部材50を、コイルスプリング20の付勢力に抗して、支持部材40から離れる方向に、略水平方向に移動させて、トレイ取付部材50の係止部50f’のストッパー40c側角部50f”を、支持部材40のストッパー40cの係合から外し、その後、係合ピン50gを中心に、トレイ取付部材50を下方に回動させることもできる。この際、ケース蓋2は、下方に回動するトレイ取付部材50の邪魔にならないように、ケース本体1の下方に位置するまで回動させておく。このように、トレイ取付部材50を下方に略垂直状態に回動させることにより、ケース本体1の開口部1aをより大きく開口することができ、ケース本体1内における種々の作業の作業性が向上することになる。
【0023】
【発明の効果】
本発明は、以上説明したような構成を有しているので、以下に記載する効果を奏することができる。
【0024】
作業中に不意に、トレイ取付部材が、支持部材から離れる方向に移動して、トレイ取付部材の係止部と支持部材のストッパーとの係合が外れて、トレイ取付部材が、自重により、下方に回動するようなことが防止できる。
