【発明の属する技術分野】
本発明は、たわみシャックルロックに係り、さらに具体的には、シャックルユニットおよびロックコアがロックケーシングから取り外すことで、シャックルユニットおよびロックコアの取替えができるたわみシャックルロックに関する。
【０００２】
【従来の技術】
たわみシャックルロックは、一般に、ロックしようとする物品を通して延びる細長いたわみシャックル部材を含んでなる。たわみシャックルロックは、複雑な構成の物品を、あるいは、一連の物品をロックするのに用いられている。
【０００３】
図１および２は、このタイプの従来のシャックルロックを示す。このシャックルロックは、ロック本体１を有し、本体１は、第１および第２シャックル孔１０１、１０２をそれぞれ設けた両端を有し内部にコンビネーションロックユニット３を備えている。細長いたわみシャックル部材７は、第１および第２シャックル接続部材７０１、７０２をそれぞれ接続された両端を有する。これら接続部材は硬質である。第１シャックル接続部材７０１は、第１シャックル孔１０１で、ロック本体１に固定されている。第２シャックル接続部材７０２は、第２シャックル孔１０２への進入が可能であり、環状溝７０３を備えている。第２シャックル接続部材７０２は、コンビネーションロックユニット３がロック状態にあるとき、コンビネーションロックユニット３のラッチ部材６と係合する。ロックユニット３を操作して解除状態にするとき、ラッチ部材６は、環状溝７０３から解放されるため、ロック本体１から第２シャックル接続部材７０２を取り外すことができる。
【０００４】
第１シャックル接続部材７０１はロック本体１に固定され、シャックル部材７の長さが一定であることから、シャックルロックは、限られた範囲でしか有用ではない。シャックル部材７を、長さの異なるものと取替え可能であるのがユーザには望ましい。さらに、ロックユニット３の取替えは、複雑で、面倒である。
【０００５】
【発明が解決しようとする課題】
従って、本発明の主な目的は、ロックケーシングから取外し可能なシャックルユニットとロックコアを備え、シャックルユニットおよびロックコアの取替えが可能なシャックルロックを提供することにある。
【０００６】
【課題を解決するための手段】
本発明のシャックルロックは、ロックケーシングと、ロックコアチャンバ内に収納されるロックコアと、シャックルユニットとを備え、ロックケーシングは、ロックコアチャンバと、ロックコアチャンバへの進入が可能で第１方向でロックコアチャンバと直線上に並ぶロックコア開口部と、第１シャックルチャンバと、第１シャックルチャンバへの進入が可能で第１方向に平行な第２方向で第１シャックルチャンバと直線上に並ぶ第１シャックル孔と、第２シャックルチャンバと、第２シャックルチャンバへの進入が可能で第２方向を横断する第３方向で第２シャックルチャンバと直線上に並ぶ第２シャックル孔と、第１チャネル形成壁によって形成され第１および第３方向を横断する第４方向に延びロックコアチャンバおよび第１シャックルチャンバと連通する第１チャネルと、第２チャネル形成壁によって形成され第２方向に延び第１シャックルチャンバおよび第２シャックルチャンバと連通する第２チャネルとを有し、ロックコアは、ラッチ部材と、キー通路とを有し、キー通路はロックコア開口部から露出し、キーを受けることによりラッチ部材が第１チャネルを通過して第１シャックルチャンバに突出するロック位置とラッチ部材が第１シャックルチャンバから離れる解除位置との間でラッチ部材を移動させるように設計されロックコア開口部を介してロックコアチャンバ内に収納され、シャックルユニットは、第１および第２シャックル接続部材と、これら第１および第２シャックル接続部材にそれぞれ接続した両端を有する細長いたわみシャックル部分とを有し、第１シャックル接続部材は、第１シャックル孔を介して第１シャックルチャンバに挿入することができ、ロック溝が設けられているため、ラッチ部材がロック位置へと移動するとき、ラッチ部材と嵌め合うことができ、第２シャックル接続部材は、第２シャックル孔を介して第２シャックルチャンバに挿入することができると共に保持部材を備え、保持部材は、第２チャネル中に延び第３方向に第２シャックル接続部材が移動するとき、第２シャネル形成壁と嵌め合うことにより第２シャックル接続部材をロックケーシング中に保持することができ、第１シャックル接続部材中のロック溝はラッチ部材が解除位置に移動するとき、ラッチ部材から解放されるため、第１シャックル孔を介してロックケーシングから第１シャックル接続部材を取り外すことができ、第１シャックル孔から第１シャックル接続部材を取り外すとき、第１シャックルチャンバおよび第２シャックル孔を介して第２チャネルに挿入される手段によって第２シャックル接続部材の保持部材に進入が可能になり、保持部材は、上記手段によって作動され第２チャネル形成壁から解放されるように設計され、これによって、第２シャックル孔を介してロックケーシングから第２シャックル接続部材を取り外すことができる。
【０００７】
【発明の実施の形態】
以下、本発明のシャックルロックの好ましい実施の形態を図面を参照して説明する。
本発明のシャックルロックは、図３ないし図６に示すように、シームレス・ロックケーシング１０と、ロックコア２０と、シャックルユニット３０とを備えている。
【０００８】
シームレス・ロックケーシング１０は、ロックコアチャンバ１１と、ロックコアチャンバ１１への進入を可能にし第１方向でロックコアチャンバ１１と直線上に並ぶロックコア開口部１２と、第１シャックルチャンバ１４と、第１シャックルチャンバ１４への進入を可能にし第１方向に平行な第２方向で第１シャックルチャンバ１４と直線上に並ぶ第１シャックル孔１４２と、第２シャックルチャンバ１５と、第２シャックルチャンバ１５への進入を可能にし第２方向を横断する第３方向で第２シャックルチャンバ１５と直線上に並ぶ第２シャックル孔１５２と、第１チャネル形成壁１４３によって形成され第１および第３方向を横断する第４方向に延びロックコアチャンバ１１および第１シャックルチャンバ１４と連通する第１チャネル１４１と、第２チャネル形成壁１５３によって形成され第２方向に延び第１シャックルチャンバ１４および第２シャックルチャンバ１５と連通する第２チャネル１５１とを有する。
【０００９】
ロックコア２０は、ラッチ部材２１とキー通路２３とを有し、キー通路２３はロックコア開口部１２から露出しキー（図示していない）を受けることによりラッチ部材２１が第１チャネル１４１を通過して第１シャックルチャンバ１４に突出するロック位置（図５および７参照）と、ラッチ部材２１が第１シャックルチャンバ１４から離れる解除位置（図８参照）との間でラッチ部材２１を移動させるように設計され、ロックコア開口部１２を介してロックコアチャンバ１１内に収納される。
【００１０】
シャックルユニット３０は、第１および第２シャックル接続部材３１、３２と、これら第１および第２シャックル接続部材３１、３２にそれぞれ両端が接続された細長いたわみシャックル部分３７とを有する。第１シャックル接続部材３１は、第１シャックル孔１４２を介して第１シャックルチャンバ１４に挿入することができ、ラッチ部材２１がロック位置へと移動するとき、ラッチ部材と係合するロック溝３１１が設けられている。第２シャックル接続部材３２は、第２シャックル孔１５２を介して第２シャックルチャンバ１５に挿入することができると共に保持部材３３を備え、保持部材３３は、第２チャネル１５１を通過し第３方向に第２シャックル接続部材３２が移動するとき、第２チャネル形成壁１５３と嵌め合うことにより第２シャックル接続部材３２をロックケーシング１０に保持することができる。第１シャックル接続部材３１のロック溝３１１は、ラッチ部材２１が解除位置に移動するとき、ラッチ部材２１から解放されるため、第１シャックル孔１４２を介してロックケーシング１０から第１シャックル接続部材３１を取り外すことができる（図９参照）。第１シャックル孔１４２から第１シャックル接続部材３１を取り外すとき、第１シャックルチャンバ１４および第１シャックル孔１４２を介して第２チャネル１５１に挿入される手段１００（図１０参照）によって第２シャックル接続部材３２の保持部材３３が進入可能になり、上記手段１００によって作動され、第２チャネル形成壁１５３から解放されるため、第２シャックル孔１５２を介してロックケーシング１０から第２シャックル接続部材３２を取り外すことができる。ロックケーシング１０は、開口ボックス１６と、上部カバー１７を有し、カバー１７は、開口ボックス１６を覆いロックケーシング１０がシームレスとなるように開口ボックス１６の上部自由端に溶接されている。
【００１１】
シャックルユニット３０の第２シャックル接続部材３２には、第２チャネル１５１と連通するスロット３２１が設けられている。保持部材３３は、スロット３２１に滑動可能に取り付けられた保持ブロック３３２と、スロット３２１に納められるバイアスばね３３３とを有する。バイアスばね３３３は、保持ブロック３３２に作用してスロット３２１から第２チャネル１５１中に挿入させることにより第２シャックル接続部材３２が、第２シャックル孔１５２を介してロックケーシング１０から外れないようにする。保持ブロック３３２は、手段１００によって第２方向に押し下げられてスロット３２１に引込めることができ、これにより、第２シャックル孔１５２を介してロックケーシング１０から第２シャックル接続部材３２を取り外すことができる。
【００１２】
ラッチ部材２１が解除位置に位置するとき、ロックコア２０が第１方向に移動すると、ラッチ部材２１は、第１チャネル形成壁１４３と嵌め合い、ロックコア開口部１２を介してロックケーシング１０からロックコア２０が外れないようにする。ラッチ部材２１は、第１シャックル接続部材３１を第１シャックル孔１４２から取り外すとき、第１シャックルチャンバ１４と第１シャックル孔１４２を介して第１チャネル１４１に挿入される手段１００によって進入可能となるため、手段１００で作動することにより第１チャネル形成壁１４３から解放され、ロックコア開口部１２を介してロックケーシング１０からロックコア２０を取り外すことができる。
【００１３】
ラッチ部材２１は、ロックコア２０からロックチャンバ１１中に第１方向に突出するラッチ基部２４を有する。ラッチ基部２４は、ロックコア２０がキー（図示していない）を介して操作されるとき、ロックコア２０のハウジングに対して回転することができる。ラッチ基部２４にはキャビティ２４０が形成されている。ラッチ部材２１は、さらに、ラッチ基部２４上に取り付けられキャビティ２４０に延びるラッチ本体２５と、キャビティ２４０内に収納されるバイアスばね２６とを有する。バイアスばね２６は、ラッチ部材２１がロック位置に位置するとき、ラッチ本体２５に作用し、ラッチ本体２５をキャビティ２４０から突出させ、ラッチ基部から第１チャネル１４１を通過して第１シャックルチャンバ１４に進入させる。ラッチ本体２５は、手段１００により、バイアスばね２６のバイアス作用に対抗して第４方向に押し下げることで、キャビティ２４０に引込めることができ、ロックケーシング１０からロックコア２０の取外しが可能になる。
【００１４】
シャックルユニット３０の第１シャックル接続部材３１は、スタッド３１２を備え、スタッド３１２は、第１シャックル接続部材３１が第１シャックルチャンバ１４に挿入されるとき、第２チャネル１５１を通過する。保持部材３３の保持ブロック３３２にはくぼみ３３１が設けられており、第１および第２シャックル接続部材３１、３２が、第１および第２シャックルチャンバ１４、１５にそれぞれ挿入されるとき、くぼみ３３１がスタッド３１２を収納し、これによって、ロックケーシング１０内の第１および第２シャックルチャンバ１４、１５の位置決めを助ける。
【００１５】
弾性ロック保護スリーブ４０は、ロックケーシング１０のスリーブを形成するスリーブ本体４６からなる。スリーブ本体４６は、その内部へのロックケーシング１０の挿入を可能にする自由端４２と、ロックケーシング１０の第１および第２シャックル孔１４２、１５２とそれぞれ直線上に並びシャックルユニット３０の第１および第２シャックル接続部材３１、３２の進入を可能にする２つの進入開口部４５とを備える。スリーブ本体４６の自由端４２には、カバーフラップ４３が蝶番式に取り付けられている。カバーフラップ４３は、ロックケーシング１０のロックコア開口部１２に向って旋回することによりロックケーシング１０を覆い、ロックコア開口部１２から離れるとき、ロックコア開口部１２を介したロックコア２０への進入を可能にする。カバーフラップ４３は、カバーフラップ４３がロックコア開口部１２を覆うとき、キー通路２３に挿入されるプラグ４４を備えている。
【００１６】
図３、図５および図７からわかるように、作動時において、第２シャックル接続部材３２が、ロックケーシング１０と係合するように第２シャックル孔１５２に挿入される。物品（図示していない）を通してロックされた後、第１シャックル接続部材３１は、第１シャックル孔１４２に挿入され、これによって、ロックコア２０のラッチ本体２５がロック溝３１１中に延び、第１シャックル接続部材３１と係合することができる。
【００１７】
図８および図９からわかるように、シャックルロックを解除するためには、対応するキー（図示していない）をキー通路２３に挿入し、ラッチ本体２５をラッチ基部２４と一緒に回し、ラッチ本体２５をロックコアチャンバ１１中に移動させることによってロック溝３１１から解放する。従って、このとき、第１シャックル孔１４２を介して第１シャックル接続部材３１をロックケーシング１０から取り外すことができる。
【００１８】
図９および図１０からわかるように、シャックル部分３７の長さが物品を通して物品をロックするのに十分ではない場合には、シャックルロック全体を取り替える必要なしにシャックルユニット３０をこれより長いものと取り替えることができる。
【００１９】
シャックルユニット３０の取替え作業は次のように行う。ロックコア２０を操作することによりラッチ部材２４を解除位置まで回転させ、第１シャックル接続部材３１を第１シャックル孔１４２から取り外す。手段１００を第１シャックル孔１４２に挿入し、保持ブロック３３２を押し下げることにより、保持ブロック３３２を第２シャックル接続部材３２のスロット３２１に引込める。このように、保持ブロック３３２は、ロックケーシング１０から解放されるため、第２シャックル孔１５２から第２シャックル接続部材３２の取外しが可能になり、これによって、ロックケーシング１０からシャックルユニット３０全体を分離することができる。その後、これより長いシャックル部分を有する別のシャックルユニットの第２シャックル接続部材３２を第２シャックル孔１５２に挿入し、ロックケーシング１０と係合させる。こうして、取替え作業は完了する。
【００２０】
図９および図１１からわかるように、腐蝕などによりロックコア２０が破損もしくは故障した場合には、ロックコア２０の取替えを次のようにして実施することができる。
【００２１】
ロックコア２０を操作してラッチ部材２４を解除位置に移動させ、第１シャックル接続部材３１を第１シャックル孔１４２から取り外す。手段１００を第１シャックル孔１４２に挿入し、ラッチ本体２５を押し下げることにより、ラッチ部材２１のラッチ基部２４内のキャビティ２４０中にラッチ本体２５を引込める。このようにして、ラッチ部材２１をロックケーシング１０から解放することにより、ロックコア開口部１２を介してロックケーシング１０からロックコア２０の取外しが可能になる。ロックコア２０の取外しの後、ロックコア開口部１２を介して、新しいロックコアをロックコアチャンバに挿入すると、新しいロックコア上のラッチ部材が第１チャネル１４１を通過してロックケーシング１０と嵌め合い取替え作業が完了する。
【００２２】
このように、ロックしようとする物品の大きさおよび形状に応じて様々な長さのシャックルユニット３０を用いて選択的にロックケーシング１０を組立て可能であることがわかる。取替え作業はユーザが容易かつ迅速に実施することができる。さらに、ロックコア２０が破損した場合には、シャックルロック全体を取り替えることなく、ロックコア２０を取り替えることができる。
【００２３】
図１２ないし図１４は、本発明に従うシャックルロックの第２の好ましい態様を示す。前記の態様とは違い、第２の好ましい態様は、駆動部材（２６、３３３）を使用することなく操作されるラッチ部材７０および保持部材８３を有する。ここで、第２態様の要素には、前記態様のものにそれぞれ対応する参照番号を用いたことに留意されたい。
【００２４】
シャックルロックの第２の態様についての詳細は、次の通りである。
ラッチ部材７０は、ロックコアチャンバ５１内にあるロックコア６０から第１方向に突出するラッチ基部７２を含み、キー（図示していない）を用いてロックコア６０を操作するとき回転可能であり、ラッチ基部７２には、第１方向に延びる保持孔７２１が設けられている。
【００２５】
ラッチ部材７０はさらに、第１シャックル接続部材８１のロック溝８１２を通過する嵌合い端７１０と、保持孔７２１に向って第４方向に嵌合い端７１０から突出する連結アーム７１１と、連結アーム７１１から保持孔７２１へと突出する嵌合い突起７１２とを有し、これによって、ラッチ基部７２の回転により、ラッチ本体７１が、ロック溝８１２を往復する第４方向に移動し（図１５および図１６を参照）、その結果、嵌め合い端７１０とロック溝８１２との嵌合いおよび解放が可能になる。
【００２６】
ラッチ基部７２は、曲面の止め壁７２２を有しており、この壁は、保持孔７２１の周囲から曲線状に延びている。ラッチ本体７１はさらに、嵌合い端７１０から止め壁７２２に向って突出する止めアーム７１３を含み、これによって、ラッチ部材７０がロック位置（図１５参照）から、解除位置（図１６参照）に移動するとき、止めアーム７１３が止め壁７２２と取外し可能に嵌め合うことにより、ラッチ基部７２がそれ以上回転するのを防止すると共に、ラッチ部材７０が解除位置からロック位置に移動するとき、止め壁７２２が嵌合いアーム７１３から離れるようにする。
【００２７】
第１シャックル接続部材８１は、２つの向き合う平面８１１を有する。ロック溝８１２は、これら平面８１１の間に延在する。ラッチ本体７１はさらに、２つの向き合う案内翼７１４を備え、案内翼７１４は、ラッチ本体７１の嵌合い端７１０から突出し、上記平面８１１とそれぞれ滑動可能に接触することにより、ラッチ本体７１の第４方向への移動を案内する。ロックケーシング５０内の第１シャックル孔５２１は、上記平面８１１に適合する２つの向き合う弦状の部分を有し、これらは、第１シャックルチャンバ５２中に第１シャックル接続部材８１を向け、挿させる上での方向マーカーとして役立つ。
【００２８】
第２シャックル接続部材８２には、シャックルキャビティ８２３と、このシャックルキャビティ８２３に連通する第１ねじ孔８２６とが設けられている。保持部材８３’は、第２ねじ孔８３０が設けられた保持本体８３を含む。ナット８２４が、シャックルキャビティ８２３中に固定されている。ボルト８３４が、第１および第２ねじ孔８２６、８３０を通って延び、上記ナット８２４とねじ結合することによって保持部材８３’を第２シャックル接続部材８２に固定する。第１シャックル接続部材８１をロックケーシング５０から取り外すとき、ボルト８３４は、第１シャックルチャンバ５２および第１シャックル孔５２１を介して進入が可能となり、これによって、第２シャックル接続部材８２からの保持部材８３’の解放と、ロックケーシング５０からの第２シャックル接続部材８２の取外しが可能になる（図１７参照）。
【００２９】
第２シャックル接続部材８２にはさらに、シャックルキャビティ８２３に隣接し第２方向に延びる第１ノッチ８２１が設けられている。また、保持部材８３には、第２ノッチ８３３が設けられ、これは、保持部材８３’が第２シャックル接続部材８２に固定されるとき第１ノッチ８２１と交差する。
【００３０】
第２シャックル接続部材８２はさらに、第２方向に延びる２つの案内８２５を備える。保持本体８３は、第２ねじ孔８３０の周辺から第２方向に延びる２つの脚８３１を有する。脚８３１には案内溝８３２が設けられ、これは、前記案内８２５と滑動可能に嵌め合うことにより、第２方向の保持部材８３’の運動を案内する。
【００３１】
保持部材８３’はさらに、第２方向に保持本体８３から突出するスタッド８３５を含む。第１シャックル接続部材８１には、くぼみ８１３が設けられ、これは、第１および第２シャックル接続部材８１、８２が第１および第２シャックルチャンバ５２、５３にそれぞれ挿入されるとき、スタッド８３５を収納するものであり、これによって、ロックケーシング５０内の第１および第２シャックルチャンバ５２、５３の位置決めを助ける。
【００３２】
ロックケーシング５０はさらに、第３チャネル５９を備え、これは、第４方向に平行な第５方向に延び、かつロックコアチャンバ５１および第２シャックルチャンバ５３と連通している。ナット５４が第３チャネル５９中に固定されている。ねじロッド５５が、ナット５４とねじ結合し、それを通過して延びることにより、ロックケーシング５０と協働してロックコア６０を締め付けるため、ロックケーシング５０からロックコア６０が外れるのを防止する。
【００３３】
ロックケーシング５０は、ロックコア開口部５０２を設けた前壁５０１を有する。ロックコア６０は、ロックコア開口部５０２に隣接する保持スロット６０１を設けた前端６０２を有する。保護プレート５６が、ロックケーシング５０内の前壁５０１と向き合って隣接しており、このプレートは、保持スロット６０１にぴったりと嵌まる挿入部分５６１を有する。保護プレート５６は、前壁５０１より硬度が高いことから、ロックコア６０を破壊から保護することができる。２個構成保護プレート５７が、ロックケーシング５０の裏壁および側壁と向き合って隣接しており、これは、保護プレート５６と同じ材料から作製されているため、ロックコア６０の破壊からの保護を強化することができる。
【００３４】
図１３と図１８からわかるように、第１および第２シャックル接続部材８１、８２の各々には、挿入孔８１７（８２７）が設けられている。挿入孔８１７（８２７）は、孔形成壁８１８（８２８）により形成されると共に細長いシャックル部分８４の両端の各々を収納する。シャックルユニット８０はさらに、２つの管状部材８６（１つだけを示す）を備え、これらは、第１および第２シャックル接続部材８１、８２の挿入孔８１７、８２７内に位置し、細長いシャックル部分８４の両端にそれぞれスリーブを形成している。
【００３５】
管状部材８６の各々は、溝の付いた複数のアーチ形部分８６１から構成され、これらは、凹凸状に相互に接続されて、管状部材８６に存在する複数の内側および外側アーチ形溝８６１１、８６１４を形成し、これによって、管状部材８６と、細長いシャックル部分８４の各端と、第１および第２シャックル接続部材８１、８２の各々の孔形成壁８１８（８２８）とが圧縮され、変形するとき、管状部材８６を介して細長いシャックル部分８４の各端と第１および第２シャックル接続部材８１、８２の各々の孔形成壁８１８（８２８）とが係合される。この圧縮中、シャックル部分８４の部分と孔形成壁８１８（８２８）の部分がそれぞれ変形することにより、内側および外側アーチ形溝８６１１、８６１４へと進入するため、管状部材８６を介してシャックル部分８４の両端を、第１および第２シャックル接続部材８１、８２に固定することができる。３つの間隔をあけたウェッジプレート８６１２が、管状部材８６の各々の一端から突出している。環状部材８６は、金属合金から作製され、第１および第２シャックル接続部材８１、８２より硬度が高いため、第１および第２シャックル接続部材８１、８２を破壊から保護することができる。
【００３６】
シャックルユニット８０はさらに、複数の金属スリーブ８５を備え、これらは、環状部材８６間の細長いシャックル部分８４にスリーブを形成する。金属スリーブ８５の各々は、ほぼ半球形の挿入端８５１と、この挿入端８５１と向き合い、かつ、挿入端８５１の形状に対応する形状をしたほぼ半球形の受け孔８５２とを有する。金属スリーブ８５と細長いシャックル部分８４とを圧縮し変形させるとき、金属スリーブ８５の各々の挿入端８５１は、当該金属スリーブ８５の隣接するスリーブの受け孔８５２に挿入され、金属スリーブ８５の隣接するもの同士ならびに金属スリーブ８５の各々と細長いシャックル部分８４とが嵌め合い、これによって、細長いシャックル部分８４を破壊から保護することができる。
【００３７】
金属スリーブ８５の最も外側にある２つの各々には、間隔をあけた３つのノッチ８５３が設けられ、これらは、環状部材８６の各々のウェッジプレート８６１２とそれぞれ嵌め合う。細長いシャックル部分８４は、ロープ状（図１３参照）、または、たわみ保護スリーブ８８を備えた鎖８７（図１９および２０を参照）状のいずれの形態をしていてもよい。鎖８７は、ピン８７２で接続された複数のリンク８７１から構成される。
【００３８】
