Description

【0001】
【発明の属する技術分野】
本発明は、引戸用ランナを走行させるレール端部に配設され、引戸を閉止する際の慣性力を減殺するとともに、跳ね返りを防止するための引戸用制動装置に関する。
【0002】
【従来の技術】
従来より、引戸においては、軽い力で開閉操作が行えるようにランナ(ローラ装置)を設けたものが多く提供されている。しかし、引戸を勢いよく閉めると、衝突音が発生したり、戸枠から跳ね返って隙間ができたりすることがあるため、この衝突音や跳ね返りを防止するためにレールの端部に引戸の慣性力を減殺させる制動装置を設けることが行われている。
【0003】
例えば、下記特許文献1においては、図8に示されるような引戸用制動装置30が提案されている。この引戸用制動装置30は、バネ作用を有する左右一対の制動片31,31(板バネ部材)により係合溝が形成された部材であって、レール端部に配設され、前記引戸32に設けられた凸状部材33が前記係合溝に嵌入する際にバネ作用により引戸32の慣性力を減殺するようになっている。このような制動装置は、通常「引戸用キャッチ」と呼ばれているものである。
【0004】
一方、例えば収納棚、食器棚、陳列棚等の収納家具等の引戸においては、引戸を閉止位置近傍まで移動させると、引戸に閉方向の付勢力が加わり、閉止位置まで誘導して隙間を空けることなく完全な閉状態とする戸締り装置(自閉装置)が設けられることがある。このような戸締り装置としては、例えば下記特許文献2などを挙げることができる。

【0006】
【発明が解決しようとする課題】
前記引戸用制動装置30により、引戸32の衝突音や跳ね返り等が防止できるようになるが、戸締まりをアシストする機能までをも有するものではない。
【0007】
一方、引戸の戸締り装置は構造が複雑であるとともに、戸枠と合わせた設計を必要とし、一般的な引戸に組込むことは困難であるとともに、価格が高価であるなどの問題があった。
【0008】
そこで本発明の主たる課題は、キャッチ式の引戸用制動装置に対して、戸締まりのアシスト機能を付加することにある。
【0009】
【課題を解決するための手段】
前記課題を解決するための請求項1に係る本発明として、開閉方向にバネ作用を有する左右一対の制動片によりピン係合溝が形成されるとともに、引戸用ランナを走行させるレール端部に配設され、前記引戸用ランナに設けられたピン部材が前記ピン係合溝に嵌入する際にバネ作用により引戸の慣性力を減殺するための引戸用制動装置において、
前記ピン係合溝は、奥端部の溝幅を前記ピン部材の径とほぼ一致させ、ピン係合溝の中間に形成された最狭部から前記奥端部までテーパー状に漸次溝幅を拡大させるように形成してあることを特徴とする引戸用制動装置が提供される。
【0010】
上記請求項1記載の本発明においては、ピン係合溝の溝形状に関し、奥端部の溝幅を前記ピン部材の径とほぼ一致させ、ピン係合溝の中間に形成された最狭部から前記奥端部までテーパー状に漸次溝幅を拡大させるように形成した。従って、前記制動片からピン部材に作用する力の奥端部方向分力により前記ピン部材が自然に奥端部側へ誘導され、奥端部位置にきっちりと停止するようになるため、引戸を閉め残しなく完全に閉止できるようになる。
【0011】
請求項2に係る本発明として、前記最狭部から前記奥端部までのテーパー長は少なくとも20mm以上としてある請求項1記載の引戸用制動装置が提供される。
【0012】
請求項3に係る本発明として、前記左右一対の制動片の先端には、相反する外側方向に突出する係合突起が夫々設けられ、これら係合突起をレールに形成された係合溝に係合させることにより前記制動片の横ブレを防止してある請求項1,2いずれかに記載の引戸用制動装置が提供される。前記制動片は張出長が長い部材であるため、ピン部材が接触した際に、左右方向に横ブレすることが予想される。従って、前記制動片の先端に係合突起を設け、これをレールの係合溝に係合させることにより横ブレを無くすことが可能となる。
【0013】
請求項4に係る本発明として、前記ピン係合溝は最狭部から開口部まで漸次溝幅を拡大させてある請求項1〜3いずれかに記載の引戸用制動装置が提供される。ピン係合溝内にピン部材が円滑に導入されるように、開口部は最狭部から漸次拡大させるようにするのが望ましい。
【0014】
【発明の実施の形態】
以下、本発明の実施の形態について図面を参照しながら詳述する。
【0015】
図1は、本発明が適用された収納棚の全体斜視図であり、図2は本発明に係る引戸用制動装置取付け部分の正面図、図3はそのIII−III線矢視図、図4は図2のIV−IV線矢視図である。
【0016】
図1に示されるように、引戸2は、例えばアルミ等の金属形材からなる上框3A、下框3B及び縦框3C、3Dによって構成されたフレーム枠3内にガラス等のパネル7が嵌め込まれたものであり、前記引戸2のフレーム枠3の裏面側にはランナ装置6(以下、単にランナという。)が取り付けられている。
【0017】
一方、収納棚1は、上板1Aの端面と下板1Bの端面とにそれぞれ水平方向に沿って上レール4A,下レール4Bが設けられ、収納棚1の開口幅約1/3幅とされる2枚の引戸2,2が前記上レール4Aおよび下レール4Bを走行ガイドとして案内される前記ランナ6により開閉自在に設けられている。なお、図示の例では、引戸2が2枚設けられた両開きタイプとしたが、収納棚1の開口幅約1/2とされる引戸2が1枚のみ設けられた片開きタイプであってもよい。
【0018】
前記ランナ6は、図2および図3に示されるように、上框3Aと縦框3Dとが交差する隅部において、一辺側6Aを上框3A方向に配向するとともに、他辺側6Bを縦框3D方向に沿って配向した状態で取り付けられている。前記一辺側6Aには、先端側にローラ部材9が支軸13によって支持されているとともに、前記支軸13を上レール4A側へ突出させ、引戸用制動装置5に対して係脱可能とされるピン部材13Aを一体的に兼用するようにしている。
【0019】
一方、前記他辺側6Bには、先端側より、水平方向に長孔の仮固定用ネジ取付孔6aと、丸孔状の2つの本固定用ネジ取付孔6b、揺動軸用ネジ孔6cが形成されており、先ず揺動軸用ネジ孔6cにネジ16を螺入し、ランナ6を揺動可能な状態で取り付けるとともに、長孔の仮固定用ネジ取付孔6aに仮止めネジ14を螺入しておくけれども締結せず、ランナ6を揺動可能な状態としておく。その後、ローラ部材9を上レール4A位置に位置決めした後、仮止めネジ14を螺入してその位置状態で仮止めし、次いで本固定用ネジ取付孔6bに本固定用ネジ15を螺入して堅固に固定を図るようにする。
【0020】
前記ローラ部材9は、図3に示されるように、実際に上レール4Aを走行する走行ローラ部9aと、前記走行ローラ部9aの外側に隣接して一体的に形成された若干大径の外れ止めローラ部9bとからなり、一方前記上レール4Aは、断面略溝型形状を成し、部材長手方向に沿って適宜の間隔で形成されたネジ取付孔4b、4b…から螺入された固定ネジ11,11…によって上板1Aの端面および下板1Bの端面にそれぞれ固定されている。また、ローラ走行部となる下フランジには凹溝4aが形成され、この凹溝4aの外側壁部の上面を前記走行ローラ部9aが走行し、前記凹溝4a内に前記外れ止めローラ部9bが嵌合するようになっており、引戸2が容易に外れないように保持されている。前記上レール4Aの端部に対し、本発明に係る引戸用制動装置5が配置されている。
【0021】
前記引戸用制動装置5は、詳細には図5に示されるように、開閉方向にバネ作用を有する左右一対の制動片5A、5Bによりピン係合溝5aが形成された部材であり、他端側にビス孔5cを有する取付用ベース板5Cが一体的に設けられ、図4に示されるように、固定ビス12により上レール4Aの端部に固定されるようになっている。そして、前記ランナ6に設けられたピン部材13Aが前記ピン係合溝5aに嵌入する際に、バネ作用により引戸2の慣性力を減殺し、戸閉止時の衝突音や跳ね返りを防止するようになっている。
【0022】
前記引戸用制動装置5について、図6に基づいて更に詳述すると、前記ピン係合溝5aは、奥端部の溝幅Dを前記ピン部材13Aの径とほぼ一致させ、ピン係合溝5aの中間に形成された最狭部から前記奥端部までテーパー状に漸次溝幅を拡大させるように形成している。この場合、前記最狭部から前記奥端部までテーパー長Lは少なくとも20mm以上、好ましくは30mm以上とするのが望ましい。なお、前記ピン係合溝5aの開口側では、前記最狭部から開口部まで漸次溝幅を拡大させ、ピン13Aが円滑にピン係合溝5a内に導かれるようにしてある。
【0023】
前記引戸2を閉め、ランナ6のピン部材13Aが前記制動装置5のピン係合溝5a内に入り込み前記最狭部を越えると、図7に示されるように、ピン部材13Aの両側から前記制動片5A、5Bによって挟閉方向に力が加わるようになる。この挟閉方向の力Fは鉛直方向成分Fと、奥端部方向成分Fとに分解することができ、前記奥端部方向成分Fの力にアシストされながらピン部材13Aは自然にピン係合溝5aの奥端部側に誘導され、引戸2の完全な閉止位置となる奥端部位置まで至り、引戸2が閉め残しなく完全に閉止されるようになる。
【0024】
ところで、前記制動片5A、5Bの先端部には、相反する外側方向に突出する係合突起5d、5eが夫々設けられ、図3に示されるように、これら係合突起5d、5eを上レール4Aに形成された係合溝4cに係合させることにより前記制動片5A、5Bの横ブレが防止されるようになっている。
【0025】
以上、引戸2の上端右側に配置されるランナ6及び引戸用制動装置5について説明を行ったが、引戸用制動装置5は下端側についても対称配置で同様に取り付けることが可能である。また、収納棚2の左側に設けられる引戸2についても同様である。
