Description

【0001】
【発明の属する技術分野】
本発明は、引戸とレールとの間に同極の磁極を向かい合わせた永久磁石を配置して引戸を浮き上がらせて滑走させる引戸装置に関する。
【0002】
【従来の技術】
従来、磁石の力により引戸を浮き上がらせるようにしたものとして、例えば特開平2001ー152748号公報に示すものがある。この従来構造のものは電機子コイルと永久磁石を組み合わせて構成されており、電気工事等の配線が必要で組み付けが非常に煩雑であり、一般家庭用としては適さない。また特開平7−18943号では引戸の下部に磁石を取り付け、敷居を金属で作って電磁誘導で引戸を浮き上がらせるアイデアが開示されている。しかしこのような構造では金属の敷居に引戸を浮き上がらせるような反発力のある磁極を誘起させることは実質的に不可能である。
【0003】
【発明が解決しようとする課題】
そこで本発明は、一般に使用されている安価な永久磁石を利用した極めて簡単な構造で引戸を確実に浮き上がらせ且つ横振れのない状態で安定して開閉操作することのできる引戸装置を簡単な構造で且つ低コストで提供することを主たる目的とするものである。
【0004】
【課題を解決するための手段】
上記目的を達成する為に本発明では次のような技術的手段を講じた。即ち、本発明に係る引戸装置にあっては、上レール2と下レール3にガイドされて走行する戸板1と、下レール3の全長にわたって磁極を上下方向に向けた状態で設置された永久磁石体4と、該永久磁石体4に対して同じ磁極を向い合わせたけた状態で前記戸板1の下面に配置された永久磁石体5とからなり、これら相対する永久磁石体4,5の反発力により戸板1が浮き上がるように形成されており、更に戸板走行時に戸板1の横振れを防止する横振れ防止部6が設けられている構造とした。これにより戸板1は相対する永久磁石体4,5の反発力により浮き上がった状態で且つ横振れのない状態で安定して走行し、軽く開閉することができる。
【0005】
また本発明では、上レール12と下レール13にガイドされて走行する戸板1と、戸板1の上端面から一体的に突出してその上端部分が前記上レール12内に挿入された磁石保持部1aと、上レール12の全長にわたって磁極を上下方向に向けた状態で該上レール内部に設置された永久磁石体14と、該永久磁石体14に相対した姿勢で且つ同じ磁極を向い合わせた状態で前記磁石保持部1a設けられた永久磁石体15とからなり、これら相対する永久磁石体14,15の反発力により戸板1が浮き上がるように形成されており、更に戸板走行時に戸板1の横振れを防止する横振れ防止部6が設けられている構造も特徴とする。この場合も上記と同じように、相対する永久磁石体14,15の反発力により戸板1が浮き上がった状態で且つ横振れのない状態で安定して走行して、軽く開閉することができる。
【0006】
前記した永久磁石体は、合成樹脂で成形された直方体状のブロックに複数の磁石を埋め込んで形成するのがこのましい。これにより、レール等への取付が容易で且つ戸板の重量に応じてその数を増減して使用することができて便利である。
【0007】
【発明の実施の形態】
以下本発明にかかる引戸装置を図面に基づいて説明する。
図1〜図3は本発明の第1の実施例を示すものであって、アルミ引き抜き材等で形成された上レール2と下レール3にガイドされて走行する戸板1が設けられている。前記下レール3にはその全長にわたって多数の永久磁石体4が磁極を上下方向に向けた状態で配置されている。また、戸板1の下面には前記永久磁石体4に対して同じ磁極を向い合わせたけた状態で多数の永久磁石体5が取り付けられている。この永久磁石体5を戸板下面に取り付けるのに、アルミ引き抜き材で形成された長尺のチャンネル材7をその溝部を下方に向けた状態で戸板1の下面に固着し、このチャンネル材7溝部に永久磁石体5を嵌めこんで適宜接着剤等で接着したり、或いはチャンネル材7の溝部に固く嵌合することにより取り付けられている。前記チャンネル材7は下レール3の溝に嵌まってスライドする実質的な戸板の滑走部としての役目をなす。
【0008】
また本実施例では前記永久磁石体4,5は、図3に示すように、それぞれ合成樹脂で成形された直方体状のブロック4a、5aに複数の磁石4b、5bを埋め込んで形成されている。そしてこのブロック状の永久磁石体の側面に横方向に沿った取り付け溝5c、5cが設けられ、この溝4c、5cが下レール3並びにチャンネル材7の内側面に形成された突条3a、7aにスライド可能に係合するように形成されている。従って、永久磁石体4,5を夫々下レール3,チャンネル材7に側端面から差し込むことによって簡単に永久磁石体4、6を取り付けることができ、同時に引戸重量に応じてその数を増減することができるので便利である。
【0009】
更に、本発明では戸板走行時に戸板1の横振れを防止する横振れ防止部6が設けられている。この実施例で示した横振れ防止部6は図3に示すように、戸板1のチャンネル材7の垂直な外側面に水平方向に延びる凸条のスレー6aを下レール3の垂直な内側面に摺接するように形成されている。尚、この凸条のスレー6aは下レール3の内側面に設けるようにしてもよい。これにより別部材を付加することなく簡単な構造で戸板1の走行時の横振れを防止することができる。またこれに代えて図4に示すように縦軸の周りで回転するローラー6bを設けてこのローラー6bが下レール3の垂直な内側面に周接することにより戸板1の横振れを防止するように形成することも可能である。
【0010】
上記のごとく構成することにより戸板1は、相対する永久磁石体4,5の反発力により浮き上がった状態で且つ横振れのない状態で安定して走行し、軽く開閉することができる。
【0011】
図5は、本発明の別の実施例を示すものであって、反発する永久磁石体を上レールと戸板の上端部とに設けたものである。この実施例では、上レール12と下レール13にガイドされて走行する戸板1と、戸板1の上端面から一体的に突出してその上端部分が前記上レール12内に挿入された磁石保持部1aと、上レール12の全長にわたって磁極を上下方向に向けた状態で該上レール内部に設置された永久磁石体14と、該永久磁石体14に相対した姿勢で且つ同じ磁極を向い合わせた状態で前記磁石保持部1a設けられた永久磁石体15とからなり、これら相対する永久磁石体14,15の反発力により戸板1が浮き上がるように形成されている。
【0012】
前記永久磁石体14,15は先に示した実施例と同じように合成樹脂で成形された直方体状のブロックに複数の磁石を埋め込んで形成されている。これにより引戸の重量に合わせてその数を増減して組み付けることができて便利である。
【0013】
更に、戸板走行時に戸板1の横振れを防止する横振れ防止部6が設けられている。本実施例において横振れ防止部6は上レール12の開口部内端に円弧状のスレー6cを形成して磁石保持部材1aの首部に摺接するように形成されている。これにより別部材を付加することなく簡単な構造で戸板1の走行時の横振れを防止することができる。またこれに代えて図6に示すように縦軸の周りで回転するローラー6dを設けてこのローラー6dが上レール12の垂直な内側面に周接するように構成し、これにより戸板1の横振れを防止させることも可能である。
【0014】
この実施例においても、先の実施例と同じように、相対する永久磁石体14,15の反発力により戸板1が浮き上がった状態で且つ横振れのない状態で安定して走行して、軽く開閉することができよう。
【0015】
以上本発明の代表的と思われる実施例について説明したが、本発明は必ずしもこれらの実施例構造のみに限定されるものではない。例えば実施例では、永久磁石体を合成樹脂製のブロック体に磁石を埋め込んで形成したが、磁石を裸のままで使用することも可能である。その他本発明では前記の構成要件を備え、かつ前記の目的を達成し、下記の効果を有する限りにおいては適宜に改変して実施することができる。
【0016】
【発明の効果】
本発明の引戸装置は上記のごとく構成したから、相対する永久磁石体の反発力により戸板は浮き上がった状態で且つ横振れのない状態で安定して走行し、軽い力で軽快に開閉することができるとともに、安価な永久磁石を利用した極めて簡単な構造でるから低コストで製作できて、一般家屋にも広く利用することができるといった効果がある。また請求項3に記載の構造とすることにより、レール等への取付が容易で且つ戸板の重量に応じてその数を増減して使用することができて便利であるといった効果がある。
