Description

【0001】
【発明の属する技術分野】
本発明は、光ファイバの余長を処理するための光ファイバコードリール台のガイド部材に関するものである。
【0002】
【従来の技術】
従来、光ファイバの余長の処理は、図10、図11に示すように光接続箱のパネル100に3個のワイヤサドル101をリール状に配置して光ファイバコードを巻回させるものであった。この場合に、各ワイヤサドル101は回転して光ファイバを傷つけることが無いように下端に張設したスナップ部101aを断面を角状に形成して該スナップ101aを嵌合するパネル100に透設した取付孔100aも角状として回転を防止する構造としたものであった。(例えば、特許文献1参照)
【0003】
【特許文献1】
特開平2002−21831号公報(図1)
【0004】
【発明が解決しようとする課題】
ところが、前記した従来のものは、パネル100に透設した取付孔100aを角状としたものであるから、各ワイヤサドル101の向きに応じるように各取付孔100aの切り抜き方向を変える必要があり、プレスの抜き角度別に金型が必要となるものであった。また、ワイヤサドル101をリール状に配置したものは配線が多数の場合には取り回しや光ファイバコードの識別が困難なものでもあった。
【0005】
【課題を解決するための手段】
前記の課題を解決するためになされた光ファイバコードリール台のガイド部材は、扇形の底板に中心側に内壁部を立設するとともに円弧側に外壁部を立設してガイド本体を形成したうえ、底板の裏面に形成した円弧側を開口させたU字状の凹段部の天井面にパネルに形成したエンボスの中央に設けた丸孔部に嵌合する突起と、該凹段部の円弧側に対向した壁面に該エンボスの周縁傾斜面に設けた丸孔部に嵌合する横向突起を設けたことを特徴とするものを請求項1に記載の発明とし、この発明において、ガイド本体の上下面に設けた連結手段により段積み可能したことを特徴とするものを請求項2に記載の発明とする。そして、これらの発明において、ガイド本体の両側面に設けた連結手段により水平連結可能としたことを特徴とするものを請求項3に記載の発明とする。
【0006】
前記した請求項1に記載の発明によれば、底板の裏面に形成した凹段部にパネルに形成したエンボスの中央に設けた丸孔部に嵌合する突起と該エンボスの周縁傾斜面に設けた丸孔部に嵌合する横向突起を設けているので、突起がパネルのエンボスの中央の丸孔部に横向突起がエンボスの周縁傾斜面の丸孔部に横方向から嵌合するものであるから、ガイド部材は前後左右、上下方向の移動と回転を規制されてパネルに取り付けられものである。そして、複数個のガイド部材がリールを構成するようにパネルに配置して取り付け光ファイバコードリール台とするものである。
【0007】
また、請求項2に記載の発明によれば、ガイド本体の上下面に設けた連結手段により段積み可能したことにより、光ファイバコードが多数の場合に上下に分離して配線できるので取り回しや光ファイバコードの識別が容易なものとなる。また、請求項3に記載の発明によれば、ガイド本体の両側面に設けた連結手段により水平連結可能としたことにより、円形のコードリールを容易に得ることができる外に、該連結手段により縦パネルへ直接取り付けることが可能なものである。
【0008】
【発明の実施の形態】
次に、本発明の実施の形態を図により説明する。
1は扇形の底板11に中心側に内壁部12を立設するとともに円弧側に外壁部13を立設して内壁部12と外壁部13との間に主ガイド部2を形成したガイド本体である。このガイド本体1の底板11の裏面には円弧側を開口させたU字状の凹段部3を形成して、該凹段部3の天井面3aに半球状の突起31を設けるとともに該凹段部3の円弧側に対向した壁面3bに横向突起32を設け、パネル4に形成したエンボス41の中央に設けた丸孔部42に突起31を嵌合させるとともに該エンボス41の周縁傾斜面41aに設けた丸孔部43に横向突起32を嵌合させてガイド本体1をパネル4に取り付けるものである。なお、外壁部13の外側両側に断面L字状の副ガイド部2aが設けられている。
【0009】
また、前記したガイド本体1の上下面には複数のガイド本体1を段積み可能とする連結手段が設けられている。この連結手段は的確に段積み可能に連結できるものであればよく、特に限定されないものであるが、図示のものは内壁部12の下端面に凹部12aを設けこれに嵌合する突部12bを上端面に設け連結可能とするとともに、内壁部12の外側中央上部に内向き爪部12cを張設して該爪部12cが対応する内壁部12の外側中央下方に係止凹部12dを設けて上下への抜け防止の手段を設けたものである。なお、このように内壁部12側に連結手段を設けた場合には図示のように外壁部13の高さを内壁部12の高さより低くして下段に位置する外壁部13の上端と上段に位置する底板11との間に配線用開口を形成することは勿論である。
【0010】
さらに、ガイド本体1の両側面にはガイド本体1同士を水平連結可能とする連結手段が設けられている。この連結手段は的確に水平連結できるものであればよく、特に限定されないものであるが、図示のものは、内壁部12の一方の側面に上下方向に一連に一対の係止部12eを張設し、これが嵌合する係止溝部12fを他方の側面に上下方向に一連に設けたものである。なお、ガイド本体1の両側面の角度を60度とすることにより6個を連結することによりサークル状のコードリール台を形成すことができる。
【0011】
このように構成されたものは、パネル4のエンボス41に底板11の裏面に形成した凹段部3を該凹段部3の開口側から嵌合して凹段部3の天井面3aに設けた突起31がエンボス41の中央に設けた丸孔部42に嵌合するとともに凹段部3の壁面3bに設けた横向突起32が該エンボス41の周縁傾斜面41aに設けた丸孔部43に横方向から嵌合するので、ガイド部材は前後左右、上下方向の移動と回転を規制されてパネルに取り付けられものである。従って、パネル4のエンボス41にはドリルにより簡単に穿つことができる丸孔部42,43を設ければよいのでパネル4の製作は容易なものである。また、図1に示すようにエンボス41の周縁傾斜面41aに丸孔部43を予め複数設けておけば、そのうち任意の丸孔部43を選択することによりガイド部材の取付方向が選択できるものである。
【0012】
そして、図5に示すようにパネル4に3個のガイド部材をリール状に配置して前記した方法で取り付けすれば、光ファイバコードリール台を形成されるので、内壁部12と外壁部13との間に形成した主ガイド部2に光ファイバコードをガイドさせて取り回して光ファイバコードの余長が処理されるものである。また、外壁部13の外側両側に断面L字状の副ガイド部2aが設けられていれば、該副ガイド部2aにも光ファイバコードを取り回して余長の処理ができるので配線の多い場合にも対応できるものである。
【0013】
また、ガイド本体1の上下面に複数のガイド本体1を段積み可能とする連結手段が設けたものであれば、図6に示すように段積みすれば、光ファイバコードの配線数が多いため例えば融着トレイを段積みして設置してある場合に対応できるうえ、上下それぞれに対応させて配線することにより光ファイバコードの識別が容易なものとなる。
【0014】
さらに、ガイド本体1の両側面にはガイド本体1同士を水平連結可能とする連結手段が設けたものであれば、ガイド本体1の両側面の角度を60度とすることにより6個を連結することにより図7,8に示すようなサークル状のコードリール台を形成したり、3個を半円状に連結したものを2組間隔をおいて配置して楕円状のコードリール台を形成することができるものである。また、ガイド本体1に設けた連結手段の一方である内壁部12の一方の側面に上下方向に一連に張設した一対の係止部12eは図9に示すように縦パネル5に設けた縦切込み5aに係合できるものであるから縦パネル5にも取り付けでき配線ガイドとして使用できるものである。
【0015】
【発明の効果】
以上に説明したように、請求項1に記載発明の光ファイバコードリール台のガイド部材は、底板の凹段部に設けた突起と横向突起をパネルに形成したエンボスの中央と周縁傾斜面に設けた丸孔部に嵌合させて取り付けるものであるから、パネルのエンボスにはドリルにより簡単に穿つことができる丸孔部を設ければよいのでパネルの製作は容易なものとなる。
【0016】
また、請求項2に記載の発明によれば、ガイド本体の上下面に設けた連結手段により段積み可能したことにより、光ファイバコードが多数の場合に上下に分離して配線できるので取り回しや光ファイバコードの識別が容易なものとなる。また、請求項3に記載の発明によれば、ガイド本体の両側面に設けた連結手段により水平連結可能としたことにより、円形のコードリールを容易に得ることができる外に、該連結手段により縦パネルへ直接取り付けることが可能なものである。
