従来、家屋に取り付けて壁面収納を設けるためのドアや家具に取り付けるドアは、ドアを前方に回転させて開閉する開き戸タイプ、ドアを折り曲げる折り戸タイプ、複数枚のドアを互い違いに配置した引き戸タイプ、複数のドアの左右の端面を互いに突き合わせて平面的な配置を可能とした面一引き戸タイプのもの等が存在した。前記開き戸や折り戸では、収納部を全開する事が可能で収納が行い易いが、開放時にドアが前面に突出したり、ドアの前方に開閉のための空間を設ける必要があり、車庫や廊下等の狭い場所での使用には不向きであるし、車椅子の使用者等では開閉作業が行いにくい。また、引き戸タイプでは開閉のための広い空間を必要とする事がないし車椅子での開閉作業も行い易いが、壁面に段差を生じて美観を損ねるし、左右のドアが重なる長さ分、収納部の左右各々の空間を全開する事はできず、収納物の目視や出し入れが行いにくく、デッドスペースを生じて、収納部全体を有効に利用する事ができなかった。
【０００４】
そこで、前記特許文献１〜１１に示す如く、ドアの平面的な閉鎖が可能で美観に優れるとともに開閉スペースを必要としない面一引き戸タイプのものも使用されている。これらの従来技術は、開放目的のドアを左右方向に移動させ、他のドア又は壁面に平行に配置するものである。そして、特許文献１の従来考案及び特許文献２の従来発明では、両端に短尺な傾斜部を設けたレール部材を設置し、このレール部材に沿って、開放目的のドアの走行体を走行させる事により、開放側のドアが斜め前方方向に平行移動させる事で、該開放側ドアを閉鎖側のドアの前面に配置し、収納部の左右何れか半分を全開する事が可能であった。
【発明が解決しようとする課題】
【０００５】
しかしながら、上記特許文献１、２の従来技術では、開放側のドアが斜め前方に平行移動する際の妨げにならない様に、互いの突合せ端面をテーパー状に加工する必要があり、製作が面倒であるし、美観を損なうものであった。
【０００６】
また、特許文献３〜６の従来発明では、レール部材の両端部に傾斜部を設け、左右のドアの両端部側の走行体は、この傾斜部により前後への移動可能とするが、突合せ端面側に接続した走行体は、レール部材に直交して進退動する切換部に係合し、この切換部が溝状の案内部内を前後に移動する事により、走行体の前後方向への移動を可能としている。そして、ドアの閉鎖時には、各ドアの両端部側の走行体は傾斜部に位置し、突合せ端面側の走行体を係合した切換部が案内部に於いてレール部材よりも後方に配置されているので、両ドアの平面的な閉鎖が可能となっている。
【０００７】
そして、ドア開放時には、開放側のドアの中央部側を手前に引くと、該ドアが傾斜部側の走行体を支軸として手前方向に回転するので、該ドアの突合せ端面側の走行体を係合した切換部が、走行体とともに案内部内を手前方向に移動し、該走行体がレール部材と同一直線上に配置され、レール部材を走行可能となるとともに、該開放側のドアの突合せ端面が他方のドアよりも前方に突出する。この突出状態で、開放側のドアの双方の走行体をレール部材に沿って走行させる事で、該開放側ドアを他方のドアの前面に平行に配置する事ができる。そして、開放側ドアの突合せ端面を、手前方向に引き出してから該ドアを移動させるので、他方のドアに突き当たる事がなく、特許文献１、２の従来技術の如く、両ドアの突合せ端面をテーパー状に面取りする必要がなく、製作が容易となるとともに美観も向上するものとなる。
【０００８】
しかしながら、上記特許文献３〜６の従来発明では、開放側ドアが手前方向に円弧状に回転するのに対し、該ドアの走行体を係合した切換部は、案内部内を前後方向に直線的に移動するものである。従って、この切換部には走行体を介して回転方向への強い剪断力が作用し、切換部の円滑な移動ができなくなったり、走行体の脱輪や、レール、切換部、案内部等の部品の摩耗等を生じる可能性が高かった。また、切換部、その他の小さな部品が多くて部品の管理も面倒であるし、工場等でレール本体や切換部を予め組み立てるものではなく、設置現場で各々の部品を組み付ける必要があるし、走行体と切換部の位置合わせ等も厳密に行う必要があり、設置作業が容易ではなかった。
【０００９】
また、前記特許文献７の従来発明では、両端に傾斜部を設けた二本のレールを、一直線上に配置するとともに中央で傾斜部を交差させ、この交差部に回転可能に可動レールを配置している。この可動レールの切り換えにより、開放側のドアの走行体が走行する側のレール部材の直線部と傾斜部とを接続させている。しかし、この従来発明の場合も、可動レールや、その切り換えのためのカム、ばね部材等の多くの部品を使用し、構成も複雑で微調整が必要であるため、組み付け性やメンテナンス性に問題があった。
【００１０】
また、特許文献８〜１１の従来発明の如く、ドアにリンクを接続して、開放側のドアを前後に移動する手法を用いたものも存在するが、これらの従来技術も、互いの突合せ端面をテーパー状に面取りする必要があり、製作上や外観上の問題があった。
【００１１】
また、上記特許文献１〜１１記載の従来技術は、何れもドアを左右方向に開放し、収納部の左右何れか半分を開放するものであり、ドアを上下方向に開放可能とするものではないし、これら従来技術を上下方向への開放が可能なスライドドアの開閉装置に応用する事は、技術的な面や操作性の点で実施が困難であった。
【００１２】
本発明は上述の如き課題を解決するため、家屋や家具に配置し、大きな開閉スペースを使用する事無く、ドアを上下にスライドさせる事で開閉が可能で、平面的な閉鎖が可能なスライドドアの開閉装置を得ようとするものである。また、このスライドドアの平面的な閉鎖により、収納部を設けた壁面や家具の美観を向上させる。また、上下方向へのドアの上下動を、お年寄りや車椅子の使用者等でも容易に行う事を可能とする。また、ドアの開放時には、収納部の上半分又は下半分を、完全に全開可能とし、収納部内の目視を明確に行い、収納物の効率的な収納を可能とするとともに、横長の収納物の収納や出し入れも容易としたり、収納棚、抽斗、収納ラック等の設置及びこれらの引き出しも容易に行う事を可能とするものである。また、ドアの上下動時の、各部品への負荷を軽減して、円滑な上下動を可能とするとともに製品の耐久性を向上させるものである。
【００１３】
尚、本明細書中にて家屋とは、一般住宅、車庫、店舗、オフィス、施設、工場等を示し、これらの家屋の室内、玄関、屋外等の壁面に、本発明のスライドドアの開閉装置を取り付けて、段差の無い平面的な壁面収納を可能とする。また、家具とは、食器棚、本棚、サイドボード、物置、各種キャビネット、その他の収納部を有するものを示し、これらに本発明のスライドドアの開閉装置を取り付ける事により、家具の美観を高めるとともに、収納物の容易な出し入れと、効率的な収納を可能とするものである。また、両側枠は、家屋や家具とは別個に製作し、該家屋や家具の両側壁等に取り付けるものであっても良いし、家屋の側壁や、家具の両側壁を、本発明のスライドドアの開閉装置用の両側枠として使用するものであっても良い。
【００１４】
【課題を解決するための手段】
本発明は、上述の如き課題を解決するため、家屋又は家具に固定する一対の両側枠を平行に配置し、この両側枠の開口部の上下方向に上部ドアと下部ドアとを端面を突き合わせ可能に配置するとともに該上部ドアと下部ドアとに、一対の両側枠の上部に配置した滑車を介して錘体を一対吊り下げて上部ドア及び下部ドアの上下動補助手段とし、前記上部ドアと下部ドアの両側に接続した走行体を摺動可能に係合するとともに前方レールと後方レールを平行に配置したレール部材を、一対の両側枠の上下両端方向で同軸上に軸支し、上部ドアと下部ドアの閉鎖時は、各レール部材の前方レールと後方レールを各々同軸上に配置し、上部ドア及び下部ドアの走行体を後方レールの軸支部方向に位置させ、上部ドア又は下部ドアの開放時には、開放側ドアの突合せ端面側を手前方向に引く事により、開放側ドアのレール部材を開放側ドアとともに軸支部を支点として手前方向に回動させ、開放側ドアの後方レールと閉鎖側ドアの前方レールとを突当て接続し、この接続した後方レールと前方レールに沿って開放側ドアの走行体を走行させる事により、開放側ドアを閉鎖側ドアの前面に平行に配置可能として成るものである。
【００１５】
また、レール部材及び／又は上下動補助手段は、一対の両側枠の開口部側の外面に固定可能な基板に予め組み付け可能としても良い。
【００１６】
また、レール部材は、位置決め手段として、上部ドア又は下部ドアの閉鎖時に後方レール側の側面を当接させるレール安定板と、上部ドア又は下部ドアの開放時に該レール部材の前方レール側の先端を突当て接触させるレール位置出し板とを設けるとともに、レール部材とレール安定板とを、固定ばねを介して回動可能に連結し、この固定ばねのばね力により、上部ドア又は下部ドアの閉鎖時はレール部材のレール安定板への当接状態を維持可能とし、上部ドア又は下部ドアの開放時は、該固定ばねのばね力に抗してレール部材を回動させてレール位置出し板に突当て接触させるとともに、上死点を越えた固定ばねのばね力により、このレール部材のレール位置出し板へ突当て接触状態を維持可能としても良い。
【００１７】
また、上部ドア及び下部ドアは、上下の位置に取手を各々設けても良い。
【００１８】
【作用】
本発明は、上述の如く構成したものであるから、一般住宅、車庫、店舗、オフィス、施設、工場等の家屋の室内外の壁面に直に取り付けて使用する事が可能であり、段差の無い平面的な外観とする事ができ、目立たず美観に優れた壁面収納が可能となる。また、食器棚、本棚、サイドボード、物置、キャビネット等の家具用のドアとして使用する事もでき、家具の美観を向上させる事が可能であるとともにドアの平面的な配置が可能であるから、収納部を減らす事無く家具の肉薄化が可能となるし、開閉のための広いスペースも必要とせず、狭い場所への設置も可能となる。また、家屋及び家具の何れに於いても、収納部の上半分又は下半分の全開が可能となり、収納物の効率的な収納及び出し入れが可能となる。
【００１９】
上記スライドドアの開閉装置の操作方法を説明する。まず、上部ドア及び下部ドアの閉鎖状態では、上部ドアを係合するレール部材と、下部ドアを係合するレール部材とが軸方向に平行に配置され、上部ドア及び下部ドアの各走行体は、各レール部材の後方レールに配置されている。この配置により、開口部の中央部側で、上部ドア及び下部ドアが互いの端面を突き合わせて同一平面上に配置され、上部ドア及び下部ドアの平面的な閉鎖が可能となっている。また、このように上部ドア及び下部ドアの平面的な配置が可能となる事により、家屋に取り付けて、壁面収納を行う場合でも、家具に取り付けた場合でも、ドアが外観的に目立たず美観に優れたものとなる。
【００２０】
そして、例えば上部ドアを開放する際は、ドア開閉作業者が上部ドアの突合せ端面側を手前方向に引くと、走行体を介して上部ドアを係合した上部側のレール部材が、軸支部を支点として上部ドアとともに手前方向に回動する。この回動により上部側のレール部材が傾斜し、該上部側のレール部材の後方レールと、下部ドアを係合する下部側のレール部材の前方レールとが突当て接続されるとともに、上部ドアの突合せ端面側が下部ドアよりも手前方向に突出する。この突出状態で、作業者が上部ドアを下方に移動させると、上部ドアの走行体が上部側のレール部材の後方レールを走行した後、下部側のレール部材の前方レールに沿って走行するので、下部ドアの前面に上部ドアを平行に配置する事ができる。
【００２１】
また、上部ドアの下降は、錘体の重量に逆らって行われるから、上部ドアの急激な落下を防いで安全な下降動作が可能となる。この上部ドアの下降により、収納部の上半分を確実に全開して、内部を容易に見渡す事が可能となり、必要な収納物を迅速に見つけ出す事ができるとともに、前面に何ら障害物が無いから、横長の収納物であっても、破損等を生じる事なく容易な出し入れが可能となる。
【００２２】
次に、上部ドアを閉鎖する場合は、開放時と逆に下部側の前方レール及び上部側の後方レールに順次沿って、上部ドアの走行体を走行させながら、上部ドアを上端まで持ち上げる。この持ち上げの際は、錘体の落下重量に補助されて上部ドアが上昇するから、作業者は少ない力で容易に上部ドアを持ち上げる事が可能である。また、この持ち上げ状態では、まだ上部ドアが傾斜しているので、上部ドアの突合せ端面側を、収納部方向に押圧すると、上部ドアとともに上部側のレール部材が回動して、軸方向に平行に配置されるので、上部ドアの平面的な閉鎖が可能となる。
【００２３】
一方、下部ドアの開放時には、下部ドアの突合せ端面側を手前方向に引いて、下部ドアとともに下部側のレール部材を手前方向に回動させる。この回動により、下部側のレール部材の後方レールと、上部側のレール部材の前方レールとが突当て接続される。この接続状態で、下部側の後方レールに走行体を係合した下部ドアを上方に移動させると、該走行体が後方レールを通過後に上部側の前方レールに沿って走行するので、下部ドアを上部ドアの前面に平行に配置させる事ができ、収納部の下半分を全開する事ができる。また、この下部ドアの移動の際も、錘体の落下重量に補助されるから、下部ドアを小さい力で容易に上方に持ち上げる事ができる。また、錘体との重量バランスにより、下部ドアと上部ドアの上昇状態を維持する事ができ、収納物の出し入れ作業中に、下部ドアと上部ドアが、不用意に落下する事故を防止し、安全な作業が可能となる。
【００２４】
また、下部ドアを閉鎖する場合には、開放時と逆に上部側の前方レール及び下部側の後方レールに順次沿って走行体を走行させながら、下部ドアを下端まで下降させる。この下降は、錘体の重量に逆らって行われるので、下部ドアの急激な落下を防いで、円滑な下降が可能となる。そして、下部ドアの下降後に、下部ドアの突合せ端面側を収納部方向に押圧すると、下部ドアとともに下部側のレール部材が回動して、軸方向に平行に配置されるので、下部ドアの平面的な閉鎖が可能となる。
【００２５】
本発明は上述の如く作用するので、従来技術の直線部と短尺で傾斜が急な傾斜部とを設けた製品に比べ、本発明では長尺なレール部材全体が傾斜するので、傾斜角度がなだらかである。そのため、走行体の脱輪等の不具合も生じにくいし、走行体やレール部材への大きな剪断力が掛かる事も無く、走行体の円滑な走行が可能となり、その結果、上部ドア及び下部ドアの容易な開閉作業が可能となる。
【００２６】
また、収納部の上半分又は下半分をほぼ全開する事ができるので、収納部及び収納物の目視確認が行い易く、収納物の出し入れ作業を効率的に行う事ができる。また、収納部の幅方向への全開が可能で、横長の収納物であっても容易な出し入れが可能となる。また、収納部内に、つり棚や抽斗、前後移動するラック等を設けて、収納部の更なる有効な使用を可能とする事も可能であるし、上部又は下部ドアの解放時には、前方に障害物が何ら配置されないので、前記抽斗やラック等を容易に引き出す事ができる。また、上部又は下部ドアを手前方向に引いた際の突出距離分の開閉スペースのみで事足りるから、駐車場や廊下等の狭い空間への取り付けも可能となるとともに、車椅子等での上部又は下部ドアの上下動操作も容易に行う事ができる。
【００２７】
また、本発明のスライドドアの開閉装置は、両側枠、上部ドア、下部ドア、レール部材、上下動補助手段等から成る簡易な構造であり、高度な微調整等を必要とする事が無く容易な組み付けが可能で、低コストな製品を得る事ができる。また、室内のみならず、玄関土間や駐車場、その他屋外等にも取り付ける事ができる。例えば玄関土間に取り付けた場合は、玄関土間を収納部の下底に兼用する事で、段差を無くして車椅子やベビーカー等の収納も容易に可能となるし、灯油タンク、靴等の汚れ物等の収納も可能であるし、掃除も容易に行えるものとなる。
【００２８】
また、上述の如く部品点数が少なく組み付け性も優れている事から、製品の設置現場で組み付けを行っても、容易な作業が可能である。しかし、レール部材及び／又は上下動補助手段は、一対の両側枠の開口部側の外面に固定可能な基板に予め組み付け可能に形成しても良い。そして、工場等で予め基板に部品を組み付け、この基板を両側枠に固定しておけば、設置現場では、前記両側枠を家屋や家具に接続固定し、レール部材に上部ドアと下部ドアを係合するだけで設置作業が完了する。従って、スライドドアの開閉装置の設置の作業効率が向上するとともに、設置現場への製品運搬時等の部品の紛失や失念も防止可能となる。また、前記レール部材や上下動補助手段を設けた基板を、家屋の壁面や家具の既存の両側壁に直に取り付けて使用する事もでき、本発明用に両側枠を別個に形成する必要がなく、低コストで汎用性に優れた製品を得る事ができる。
【００２９】
また、レール部材は、位置決め手段として、上部ドア又は下部ドアの閉鎖時に後方レール側の側面を当接させるレール安定板と、上部ドア又は下部ドアの開放時に該レール部材の前方レール側の先端を突当て接触させるレール位置出し板とを設け、レール部材とレール安定板とを、固定ばねを介して回動可能に連結しても良い。そして、固定ばねのばね力により、上部ドア又は下部ドアの閉鎖時はレール部材のレール安定板への当接状態を維持可能とする事で、多少の振動や衝撃等ではレール部材が不用意に回動する事はない。そして、上部ドア又は下部ドアの開放時は、該固定ばねのばね力に抗してレール部材を回動して、レール位置出し板に突当て接触させ、上死点を越えた固定ばねのばね力により、このレール部材のレール位置出し板へ突当て接触状態を維持可能とする事で、上部ドア又は下部ドアの開放時に於いても、レール部材がレール安定板方向に不用意に復元回動する事がなく、上部ドア又は下部ドアの円滑な上下動操作が可能となる。
【００３０】
また、上部ドア及び下部ドアは、上下の位置に取手を各々設ければ、各ドアの手前方向への引き出しや、上下動操作が容易なものとなる。また、複数の取手を上下の何れかの位置に配置する事で、上部ドア又は下部ドアの位置に応じて取手を持ち替えながら上下動操作を行う事ができ、作業者が大きく腰を屈める事等が無く、お年寄りや車椅子使用者等でも容易な上下動操作が可能となる。
【００３１】
【実施例】
以下、本発明のスライドドアの開閉装置を一般住宅、車庫、店舗、オフィス、施設、工場、その他の家屋の壁面に取り付けて、壁面収納を設けた一実施例を図面に於いて詳細に説明する。図１は、上部ドアと下部ドアの閉鎖時の側面図で、図２は上部ドアの開放のため、上部ドアを手前方向に引いて上部側のレール本体を傾斜させた状態の側面図、図３は上部ドアの開放状態を示す側面図である。また、図４は下部ドアの開放のため、下部ドアを手前方向に引いて下部側のレール本体を傾斜させた状態の側面図で、図５は下部ドアの開放状態の側面図である。
【００３２】
また、図６は図１に於けるレール部材の中央部側の拡大斜視図で、上部側と下部側のレール部材が同軸上に配置された状態を示し、図７は図２に於けるレール部材の中央部側の拡大斜視図で、上部側のレール部材の回動により、上部側の後方レールと下部側の前記レールとが突当て接続された状態を示す。また、図８は図１のＡ−Ａ線断面図で、錘体と滑車の位置関係を示し、図９は図１のＢ−Ｂ線拡大断面図で、走行体が後方レールに位置した状態を示し、図１０は図３のＣ−Ｃ線拡大断面図で、上部ドアと下部ドアとの積層時の走行体の位置関係を示す。また、図１１は上部ドアと下部ドアの閉鎖状態の斜視図である。
【００３３】
まず、本発明のスライドドアの開閉装置の構成を説明すると、（１）は一対の両側枠で、家屋の壁面（２）に垂直に取り付けて、背面壁（９）、天板（３）、地板（４）及び両側枠（１）とで囲繞された空間を収納部（５）としている。そして、前記一対の両側枠（１）の開口部（６）に、上下方向に移動可能に上部ドア（７）と下部ドア（８）を配置している。この上部ドア（７）の下端面と下部ドア（８）の上端面を、互いに突き合わせ可能な突合せ端面（１０）とし、この互いの突合せ端面（１０）を開口部（６）の中央部で互いに突き合わせる事により、上部ドア（７）と下部ドア（８）とを段差の無い同一平面上に配置可能としている。また、前記天板（３）、地板（４）を本発明用に別個に設けずに、家屋の天井や床面（２９）、土間等をそのまま使用するものであっても良い。また、両側枠（１）として、スライドドアの開閉装置を設置する家屋の側面壁を利用しても良い。
【００３４】
そして、上記両側枠（１）の開口部（６）側に、一対の基板（１１）を固定し、この基板（１１）に、一対のレール部材（１６）（１７）を、上下両端方向で軸支して同軸上に配置している。この一対のレール部材（１６）（１７）は、断面コ字形とし前方レール（１２）（１３）と後方レール（１４）（１５）を各々平行に突設するとともに、各軸支部（１８）（１９）を支点に手前方向に回動可能とし、上部ドア（７）と下部ドア（８）の閉鎖時は、同一直線上に配置され、互いの前方レール（１２）（１３）及び後方レール（１４）（１５）とが各々突当て接続している。一方、上部ドア（７）又は下部ドア（８）の開放時には、軸支部（１８）（１９）を介して一方又は他方のレール部材（１６）（１７）が手前方向に回動し、一方の後方レール（１４）（１５）と他方の前方レール（１３）（１２）とが突当て接続可能となっている。
【００３５】
また、レール部材（１６）（１７）は、回動時の位置決め手段（３７）として、上部ドア（７）又は下部ドア（８）の閉鎖時に後方レール（１４）（１５）側の側面を当接可能なレール安定板（２１）を、基板（１１）の中央部に固定し、このレール安定板（２１）に当接する事で、レール部材（１６）（１７）を軸方向に平行に配置可能としている。更に、レール安定板（２１）に、レール部材（１６）（１７）の回動間隔を介してレール位置出し板（２０）を設け、上部ドア（７）又は下部ドア（８）の開放時に、一方のレール部材（１６）（１７）が回動して前記レール位置出し板（２０）に突当て接触する事で、一方の前方レール（１２）（１３）と他方の後方レール（１４）（１５）との確実な位置決めと接続とを可能としている。
【００３６】
更に、各レール部材（１６）（１７）には、クランク状の支持板（２２）を固定し、各支持板（２２）と、前記レール安定板（２１）とを、各々固定ばね（２３）を介して回動可能に連結している。この固定ばね（２３）のばね力により、レール部材（１６）（１７）は、上部ドア（７）又は下部ドア（８）の閉鎖時はレール安定板（２１）への当接位置に係合され、振動や衝撃等の多少の負荷では回動する事はなく、軸方向への平行な配置が保たれている。また、ドア開閉作業者による回動力が作用した場合のみ、固定ばね（２３）のばね力に抗してレール部材（１６）（１７）が作業者方向の手前方向に回動し、レール位置出し板（２０）に突当て接触するとともに、固定ばね（２３）のばね力が再び作用して、この回動先にてレール部材（１６）（１７）が安定的に固定される。従って、次に人手による戻し力が加わるまでは、レール部材（１６）（１７）が不用意に元位置に復元回動する事はなく安全性が保たれるとともに優れた操作性も得られる。
【００３７】
そして、前記レール部材（１６）（１７）に、前記上部ドア（７）と下部ドア（８）とを、摺動可能に係合している。この上部ドア（７）及び下部ドア（８）は、図１〜図５、図８〜図１１に示す如く、上下端部側の両側に、側面Ｌ字型の連結体（２４）（２５）を一対ずつ接続し、この連結体（２４）（２５）に、ローラー等から成る走行体（２６）（２７）を上下に一対ずつ接続し、各走行体（２６）（２７）を、両側枠（１）に配置したレール部材（１６）（１７）の後方レール（１４）（１５）に係合している。また、上記連結体（２４）（２５）を介した各ドア（７）（８）と走行体（２６）（２７）との間隔は、各ドア（７）（８）の肉厚よりも大きいものとし、一方のドア（７）（８）の前記間隔内に他方のドア（８）（７）を積層配置できるようにしている。
【００３８】
また、上部及び下部ドア（７）（８）の外表面には、図１１に示す如く、取手（２８）を上下に一対ずつ凹設し、後述の如く、作業者が各上部及び下部ドア（７）（８）の上下動操作を行い易い構造としている。
【００３９】
また、上記上部ドア（７）及び下部ドア（８）は、使用目的や設置場所の環境、デザイン性、コスト等に応じて、表面仕上げを木質系、金属系、樹脂系の何れとしても良いが、寝室や居間、その他の室内に取り付ける場合等は、壁面（２）の壁紙と同一のものを上部ドア（７）及び下部ドア（８）に貼着する事で、壁面（２）との同一感が高まり、目立たず美観に優れた壁面収納が可能となる。
【００４０】
また、上部ドア(７)と下部ドア(８)との上下動を容易に行うため、上下動補助手段(３４)を設けている。この上下動補助手段( ３４ )の構成は、一対の各両側枠(１)に於いて、上部ドア(７)の一対の連結体(２４)と下部ドア(８)の一対の連結体(２５)とを、一対のワイヤー(３０)で連結している。そして、この一対のワイヤー(３０)に、両側枠(１)の上端に配置した４個の滑車(３１)を介して、一対の錘体(３２)を吊り下げている。また、この錘体(３２)は、錘体(３２)に回動可能に固定した支持滑車(３３)を、ワイヤー(３０)に係合する事により吊り下げて、各ドア(７)(８)の上下動した際に、錘体(３２)とワイヤー(３０)との自在な相対摺動を可能としている。
【００４１】
また、一対の錘体（３２）の合計重量は、上部及び下部ドア（７）（８）の合計重量と略同一とする事により、上部及び下部ドア（７）（８）の上下動を容易なものとするとともに、重量バランスが保たれ、上部ドア（７）と下部ドア（８）の閉鎖状態、或いは開放状態を維持可能となる。また、錘体（３２）は、適宜の重量のものを選択的に取り付けて、重量調節可能とする事により、重量バランスを微妙に調整して、上部及び下部ドア（７）（８）のより円滑な上下動を可能としている。
【００４２】
上述の如く構成したスライドドア開閉装置に於いて、上部ドア（７）と下部ドア（８）の閉鎖時は、図１に示す如く、レール部材（１６）（１７）は互いに同軸上に配置され、上部ドア（７）の走行体（２６）及び下部ドア（８）の走行体（２７）は、各々後方レール（１４）（１５）の上下の軸支部（１８）（１９）寄りに位置し、上部ドア（７）と下部ドア（８）とが開口部（６）の中央部に於いて突合せ端面（１０）を互いに突き合わせて、同一平面上に配置されている。従って、上部ドア（７）と下部ドア（８）とは、段差が何ら生じる事の無い平面的な閉鎖が可能で、目立たず美観に優れたものとなる。
【００４３】
また、前述の如く、固定ばね（２３）のばね力により、各ドア（７）（８）を係合したレール部材（１６）（１７）が同軸上に固定配置され、上部ドア（７）と下部ドア（８）の平面的な閉鎖状態を保っているが、本実施例では更に、図１に示す如く、閉鎖時の上部ドア（７）の連結体（２４）に臨ませて、Ｌ字形の下り止め（３５）を、下部ドア（８）の連結体（２５）に臨ませて、Ｌ字形の上り止め（３６）を、各々基板（１１）に設けている。この下り止め（３５）及び上り止め（３６）に、各連結体（２４）（２５）が突き当たる事により、閉鎖時に於ける上部ドア（７）と下部ドア（８）との不用意な下降や上昇を防止して、より安定した閉鎖を保っている。また、レール部材（１６）（１７）は、軸支部（１８）（１９）側に、上部ドア（７）と下部ドア（８）の開放動作時に、連結体（２４）（２５）の端部を突き当て可能なストッパー（図示せず）を設ければ、上部ドア（７）と下部ドア（８）の過剰な下降や上昇が防止可能となるし、耐衝撃性も向上する。
【００４４】
そして、例えば上部ドア（７）を開放する際は、作業者は上部ドア（７）の下方の取手（２８）を保持して、上部ドア（７）等を手前方向に引く動作を行うと、該上部ドア（７）を係合した上部側のレール部材（１６）が、図２、図７に示す如く、固定ばね（２３）のばね力に抗して軸支部（１８）を支点に手前方向に回動する。このレール部材（１６）の回動により、該レール部材（１６）の後方レール（１４）と、下部側のレール部材（１７）の前方レール（１３）とが突当て接続するとともに、上部ドア（７）の突合せ端面（１０）が下部ドア（８）よりも手前方向に突出し、上部ドア（７）の連結体（２４）と下り止め（３５）との係合が解除される。この突出状態で、作業者が上部ドア（７）を下方に移動させると、上部ドア（７）の走行体（２６）が上部側の後方レール（１４）を走行した後、下部側の前方レール（１３）を走行する事で、上部ドア（７）は下部ドア（８）に突き当たる事のない移動が可能となり、図３に示す如く、下部ドア（８）の前面に上部ドア（７）を平行に配置する事ができる。
【００４５】
また、この上部ドア（７）の下降は、錘体（３２）の重量に逆らって行うから、上部ドア（７）の急激な落下を防止して、安全な下降動作が可能となる。また、この下降の際、下降途中まで下方側の取手（２８）を保持して行うが、適宜の位置まで下降させたら、今度は上部ドア（７）の上方に設けた取手（２８）に持ち換えて下降作業を行う事により、作業者が腰を大きく屈める事なく、上部ドア（７）を下端まで容易に下降させる事ができ、お年寄りや車椅子使用者等であっても、容易な開放動作が可能となる。また、下降後は錘体（３２）により重量バランスを取っているから、上部ドア（７）が不必要に上昇する事がなく、下降状態を保持して、作業者が安全に収納物の出し入れ作業を行う事ができる。
【００４６】
そして、従来技術では、開放側のドアを手前方向に引き出してレール部材の切り換え作業を行う際に、切換部に強い剪断力が掛かって円滑な回動ができなくなったり、脱輪や部品の摩耗等を生じる可能性があったが、本発明では、上部ドア（７）とともに長尺なレール部材（１６）全体が軸支部（１８）を支点として回動するので、回動時に各種部材に強い剪断力が掛かる事がないし、回動後のレール部材（１６）の傾斜もなだらかで、走行体（２６）の脱輪を生じにくく円滑な走行が可能となるとともに、レール部材（１６）（１７）や走行体（２６）（２７）等の部品の摩耗も防いで装置の耐久性も向上するものとなる。
【００４７】
上述の如く、上部ドア（７）を下降する事により、図３に示す如く、収納部（５）の上半分を幅方向にほぼ全開する事ができ、収納部（５）内及び収納物の目視を明確かつ迅速に行う事ができる。また、正面に何ら障害物がないから、横長の収納物であっても容易に出し入れ作業を行う事ができる。また、収納部（５）に任意のサイズの吊り棚や抽斗、前後移動するラック等を設置する事も可能となり、収納部（５）の有効な活用と整理整頓が可能となるし、抽斗やラックの出し入れも何ら支障なく円滑に行う事が可能となる。また、上部ドア（７）を手前方向に回動させた際の突出距離分の開閉スペースのみ必要で、開閉動作に場所を取らず、駐車場や廊下等の狭い空間への取り付けも可能となる。
【００４８】
次に、上部ドア（７）を閉鎖する場合は、開放時とは逆の手順で、上部ドア（７）の上方の取手（２８）を保持して、上部ドア（７）を上方に引き上げると、上部ドア（７）の走行体（２６）が下部側の前方レール（１３）を通過後、上部側の後方レール（１４）を走行し、上部ドア（７）が開口部（６）の上端に到達する。また、この引き上げ途中で、上部ドア（７）の上方の取手（２８）から下方の取手（２８）に持ち替えて操作する事で、作業者は負担の少ない動作が可能となるし、上部ドア（７）の上昇が錘体（３２）の落下重量に補助されているので、作業者は小さな力で円滑に上部ドア（７）を持ち上げる事ができる。
【００４９】
また、上部ドア（７）を上端まで持ち上げただけでは、図２に示す如く、上部ドア（７）は突合せ端面（１０）側が手前方向に突出し傾斜している。そのため、作業者は、上部ドア（７）の突合せ端面（１０）側を収納部（５）方向に押圧する事により、上部ドア（７）とともに上部側のレール部材（１６）が回動し、軸方向に平行に配置されるので、図１に示す如く、上部ドア（７）が平面的に閉鎖されるものとなる。また、この閉鎖により、上部ドア（７）の連結体（２４）が下り止め（３５）に係合するから、上部ドア（７）の重量が下部ドア（８）に掛かる事がなく、錘体（３２）の作用も相俟って、後述の下部ドア（８）の上下動操作に支障を与える事がなく、上部ドア（７）が不必要に下降する不具合も防ぐものとなる。
【００５０】
一方、下部ドア(８)を開放するには、下部ドア(８)の上方の取手(２８)を手前方向に引いて、図４に示す如く、下部ドア(８)とともに下部側のレール部材(１７)を軸支部(１９)を支点として手前方向に回動させる。この回動により、図４に示す如く、下部側のレール部材(１７)の後方レール(１５)と、上部側のレール部材(１６)の前方レール(１２)とが連続するので、この後方レール( １５ )と前方レール(１２)とに沿って下部ドア(８)の走行体(２７)が走行して下部ドア(８)が上昇するから、図５に示す如く、下部ドア(８)を上部ドア(７)の前面に配置させる事ができる。
【００５１】
また、この下部ドア（８）の上昇の際も、動作途中で上方の取手（２８）から下方の取手（２８）に持ち替える事により、お年寄りや車椅子使用者等でも、楽な姿勢で容易な開放動作が可能となる。また、錘体（３２）の落下重量に補助されて、下部ドア（８）を小さい力で容易に上方に持ち上げる事ができるし、下部ドア（８）の上昇状態を保って、収納部（５）の下半分への収納物の出し入れ作業中に、下部ドア（８）が不必要に落下する事はなく、安全な作業が可能となる。また、そして、下部ドア（８）の上昇により、収納部（５）の下半分を幅方向にほぼ全開する事ができ、収納部（５）の目視が容易で、効率的な収納が可能となる。
【００５２】
次に、下部ドア（８）を閉鎖する際は、下方の取手（２８）を保持して下部ドア（８）の下げ動作を行うと、該ドア（８）の走行体（２７）が上部側の前方レール（１２）、下部側の後方レール（１５）に沿って走行し、図４に示す如く、下部ドア（８）を開口部（６）の下端に容易に移動させる事ができる。そして、下部ドア（８）の突合せ端面（１０）側を収納部（５）方向に押圧する事により、下部側のレール部材（１７）が回動して軸方向に平行に配置されるので、図１に示す如く、下部ドア（８）を平面的に閉鎖する事ができる。
【００５３】
また、上記実施例では、上部ドア（７）及び下部ドア（８）の表面を凹設して取手（２８）を設けているが、フック状の取手（２８）を突設しても良い。又は、通常は上部ドア（７）や下部ドア（８）の表面と面一に埋設され、使用時のみ外部に突出して手指で保持する事ができるような取手（２８）とすれば、上部ドア（７）と下部ドア（８）の閉鎖時は、取手（２８）が目立たず、美観にも優れたものとなる。
【００５４】
また、本発明のスライドドアの開閉装置は、主に両側枠（１）とレール部材（１６）（１７）及び上部ドア（７）、下部ドア（８）、上下動補助手段（３４）等から成る簡易な構造なので、室内のみならず、玄関土間や駐車場、その他屋外等にも取り付ける事ができる。そして、例えば玄関土間に取り付けて、玄関土間を地板（４）として使用すれば、玄関土間と収納部（５）との段差を無くして、車椅子やベビーカー等の収納も容易に可能となるし、灯油タンク、靴等の汚れ物等の収納も可能となるとともに、掃除も容易となる。また、家屋の壁面（２）に、スライドドアの開閉装置を一セットのみ設けても良いが、横方向に複数セットのスライドドアの開閉装置を設置する事も可能で、より効率的な壁面収納が可能となるとともに、全てのスライドドアの平面的な閉鎖により、家屋の壁面（２）との一体感が出て目立たず、美観にも優れたものとする事ができる。
【００５５】
また、第１実施例では、家屋の壁面（２）に本発明を設置しているが、他の異なる実施例として、食器棚、本棚、サイドボード、物置、その他の各種キャビネット等、家具用のスライドドアの開閉装置として使用する事ができ、表面に段差が無く美観に優れた肉薄な製品を得る事ができるし、ドア開閉のための広いスペースも必要ないので、狭い場所への家具の設置が可能となる。また、収納物の目視も容易で出し入れの作業性が向上し、更に収納部の有効活用が可能となる。
【００５６】
また、上記第１実施例では、上部ドア（７）と下部ドア（８）の走行体（２６）（２７）を係合するレール部材（１６）（１７）を、断面コ字形に成形して、突起状の前方レール（１２）（１３）と後方レール（１４）（１５）を設けているが、他の異なる実施例として、レール部材（１６）（１７）を凹設して、凹溝状の前方レール（１２）（１３）と後方レール（１４）（１５）としても良い。
【００５７】
【発明の効果】
本発明は上述の如く構成したものであるから、設置場所を限定する事なく、上下方向にスライド可能で、収納部の上半分又は下半分を開放可能なスライドドアの開閉装置を得る事ができる。また、収納部の上半分又は下半分を各々全開する事ができ、収納部内の目視を迅速かつ容易に行え、目的の収納物の出し入れ作業を効率的に行う事ができる。また、本発明では収納部の幅方向の全開が可能となり、横長の収納物であっても容易な出し入れが可能となる。また、ドアの開閉動作の際に、従来の開き戸や折り戸の如く、広い開閉スペースを必要とする事なく、上下各ドアの突合せ端面側の突出距離分のスペースのみで事足りるので、狭い場所への設置も可能となる。また、ドア開放時には、長尺なレール部材全体が上部ドア又は下部ドアとともに回動するので、走行体の脱輪や部品の摩耗等が生じにくく、開放側のドアの円滑な上下動が可能となる。

[0003]
Conventionally, doors to be installed on a house to provide wall storage and doors to be installed on furniture are a swing door type that opens and closes by turning the door forward, a folding door type that folds the door, and a sliding door type that arranges multiple doors alternately. There has been a flush door type in which left and right end surfaces of a plurality of doors are abutted to each other to enable a planar arrangement. In the case of the hinged doors and folding doors, the storage section can be fully opened and storage is easy, but when the door is opened, the door must protrude to the front or a space for opening and closing must be provided in front of the door, such as a garage or a corridor. It is unsuitable for use in narrow places, and it is difficult for a wheelchair user or the like to open and close. In addition, the sliding door type does not require a large space for opening and closing, and it is easy to open and close with a wheelchair.However, it creates a level difference on the wall surface and impairs aesthetics, and the length of the left and right doors overlap, The left and right spaces could not be fully opened, and it was difficult to visually check and take in and out the stored items, and a dead space occurred, making it impossible to effectively use the entire storage portion.
[0004]
Therefore, as shown in Patent Documents 1 to 11, a flush door type that can close a door in a planar manner, is excellent in aesthetic appearance, and does not require an opening and closing space is also used. In these prior arts, a door to be opened is moved in the left-right direction and is arranged parallel to another door or a wall surface. According to the conventional invention of Patent Document 1 and the conventional invention of Patent Document 2, a rail member having short inclined portions provided at both ends is installed, and a traveling body of an opening door is run along the rail member. Thus, by moving the open-side door parallel to the diagonally forward direction, the open-side door can be disposed in front of the closed-side door, and either the left or right half of the storage unit can be fully opened.
[Problems to be solved by the invention]
[0005]
However, in the prior arts of Patent Literatures 1 and 2, it is necessary to machine the butted end surfaces of each other into a tapered shape so as not to hinder the opening-side door from moving obliquely forward. Yes, it was a bad thing.
[0006]
Further, in the conventional inventions of Patent Documents 3 to 6, inclined portions are provided at both ends of the rail member, and the traveling bodies at both ends of the left and right doors can be moved back and forth by the inclined portions. The traveling body connected to the side engages with a switching portion that moves forward and backward perpendicular to the rail member, and this switching portion moves back and forth in the groove-shaped guide portion, thereby moving the traveling body in the front-rear direction. It is possible. When the doors are closed, the traveling bodies on both ends of each door are located on the inclined portion, and the switching portion engaging the traveling body on the butt end surface side is disposed behind the rail member in the guide portion. As a result, both doors can be closed two-dimensionally.
[0007]
Then, when the door is opened, if the central portion of the door on the open side is pulled toward the front, the door rotates forward with the running body on the inclined side as a support shaft, so that the running body on the butted end face side of the door is rotated. The engaged switching portion moves forward in the guide portion together with the traveling body, and the traveling body is disposed on the same straight line as the rail member, so that the rail member can travel, and the abutting end face of the door on the open side. Project forward from the other door. In this protruding state, by moving both running bodies of the open side door along the rail member, the open side door can be arranged in parallel with the front surface of the other door. Then, since the butt end face of the open side door is pulled out in the forward direction and the door is moved, the butt end face of both doors is tapered as in the prior arts of Patent Documents 1 and 2 without hitting the other door. There is no need to chamfer the shape, which facilitates the production and improves the appearance.
[0008]
However, in the conventional inventions of Patent Documents 3 to 6, the open-side door rotates in a circular arc shape in the forward direction, whereas the switching unit engaged with the traveling body of the door linearly moves in the guide portion in the front-rear direction. The thing that moves to. Therefore, a strong shearing force in the rotation direction acts on the switching unit via the traveling body, and the switching unit cannot move smoothly, or the traveling body cannot be derailed or the rails, the switching unit, the guide unit, etc. There was a high possibility that parts would be worn. Also, there are many switching parts and other small parts, so it is troublesome to manage the parts, and it is necessary to assemble each part at the installation site instead of assembling the rail body and the switching part in advance at the factory etc. It was necessary to strictly adjust the position of the body and the switching section, and the installation work was not easy.
[0009]
Further, in the conventional invention of Patent Document 7, two rails provided with inclined portions at both ends are arranged on a straight line, and the inclined portions intersect at the center, and a movable rail is rotatably arranged at the intersection. ing. The switching of the movable rail connects the linear portion and the inclined portion of the rail member on the side on which the traveling body of the open door runs. However, even in the case of this conventional invention, many parts such as a movable rail, a cam for switching the movable rail and a spring member are used, and the configuration is complicated and fine adjustment is required. was there.
[0010]
Further, as in the prior arts of Patent Literatures 8 to 11, there are methods using a method of connecting a link to a door and moving an open side door back and forth, but these prior arts also have a butt end face of each other. Has to be chamfered in a tapered shape, and there are problems in manufacturing and appearance.
[0011]
Further, the prior arts described in the above Patent Documents 1 to 11 all open the door in the left-right direction and open either the left or right half of the storage unit, and do not make the door openable in the up-down direction. However, it is difficult to apply these conventional techniques to a sliding door opening / closing device that can be opened in the vertical direction in terms of technical aspects and operability.
[0012]
The present invention solves the above-mentioned problems by disposing in a house or furniture and opening / closing by sliding the door up and down without using a large opening / closing space, and a sliding door that can be closed flatly. It is intended to obtain an opening / closing device. Further, by the planar closing of the sliding door, the beauty of the wall surface and the furniture provided with the storage section is improved. In addition, the vertical movement of the door in the vertical direction can be easily performed by an elderly person, a wheelchair user, and the like. In addition, when the door is opened, the upper half or lower half of the storage section can be fully opened, the inside of the storage section can be clearly seen, and efficient storage of storage is possible. This facilitates storage and unloading, and also facilitates installation of storage shelves, drawers, storage racks, and the like, and drawers thereof. In addition, the load on each part when the door is moved up and down is reduced, enabling smooth up and down movement and improving the durability of the product.
[0013]
In this specification, a house refers to a general house, a garage, a store, an office, a facility, a factory, and the like, and a sliding door opening / closing device of the present invention is provided on a wall surface such as indoor, entrance, or outdoor of these houses. To enable flat wall storage without steps. Furniture refers to those having a cupboard, bookcase, sideboard, storeroom, various cabinets, and other storage sections. By attaching the sliding door opening and closing device of the present invention to these, the beauty of the furniture is enhanced. This enables easy storage and removal of stored items and efficient storage. Further, the both side frames may be manufactured separately from the house or the furniture and attached to the both side walls of the house or the furniture, or the side walls of the house or the both side walls of the furniture may be formed by the sliding door of the present invention. May be used as both side frames for the switchgear.
[0014]
[Means for Solving the Problems]
The present invention, in order to solve the above-described problem, arranges a pair of both side frames fixed to a house or furniture in parallel, and the upper door and the lower door can abut the end faces in the vertical direction of the opening of the both side frames. And a pair of weights are suspended from the upper door and the lower door via pulleys disposed above the pair of side frames to provide vertical movement assisting means for the upper door and the lower door. A rail member, which slidably engages a traveling body connected to both sides of the door and has a front rail and a rear rail arranged in parallel, is coaxially supported in the upper and lower directions of a pair of both side frames, and cooperates with the upper door. When the lower door is closed, the front rail and the rear rail of each rail member are arranged coaxially, the traveling body of the upper door and the lower door is positioned in the direction of the support of the rear rail, and the upper door or the lower door is opened. Sometimes open By pulling the butting end face side of the door forward, the rail member of the open door is rotated forward with the open door as a fulcrum around the pivot, so that the rear rail of the open door and the front rail of the closed door are And the traveling body of the open-side door runs along the connected rear rail and front rail, so that the open-side door can be arranged in parallel with the front surface of the closed-side door.
[0015]
Further, the rail member and / or the vertical movement assisting means may be pre-assembled on a substrate which can be fixed to the outer surfaces of the pair of side frames on the opening side.
[0016]
Further, the rail member, as positioning means, a rail stabilizer plate that abuts the side surface on the rear rail side when the upper door or the lower door is closed, and the front rail side end of the rail member when the upper door or the lower door is opened. A rail positioning plate for abutting contact is provided, and the rail member and the rail stabilizing plate are rotatably connected via a fixed spring. When the upper door or the lower door is closed by the spring force of the fixed spring. Makes it possible to maintain the contact state of the rail member with the rail stabilizing plate, and when the upper door or the lower door is opened, rotates the rail member against the spring force of the fixed spring and projects the rail member to the rail positioning plate. The contact between the rail member and the rail positioning plate may be maintained by the spring force of the fixed spring beyond the top dead center.
[0017]
The upper door and the lower door may be provided with handles at upper and lower positions, respectively.
[0018]
[Action]
Since the present invention is configured as described above, it can be used by directly attaching to the indoor and outdoor wall surfaces of a house such as a general house, a garage, a store, an office, a facility, and a factory, and has no steps. It can have a flat appearance and can be stored on the wall without any noticeability. In addition, it can also be used as a door for furniture such as cupboards, bookshelves, sideboards, storerooms, cabinets, etc., and it is possible to improve the beauty of the furniture and to arrange the doors in a plane, Furniture can be made thinner without reducing the number of storage sections, and a large space for opening and closing is not required, and installation in a narrow place is also possible. Further, in both the house and the furniture, the upper half or the lower half of the storage section can be fully opened, and the storage and storage of the storage can be efficiently performed.
[0019]
An operation method of the opening / closing device for the slide door will be described. First, in the closed state of the upper door and the lower door, the rail member engaging the upper door and the rail member engaging the lower door are arranged in parallel in the axial direction. , Are arranged on the rear rail of each rail member. With this arrangement, the upper door and the lower door are arranged on the same plane with their end faces abutting each other on the center side of the opening, and the upper door and the lower door can be closed two-dimensionally. In addition, since the upper door and the lower door can be arranged in a planar manner in this manner, the door is not visually conspicuous even when it is attached to a house and stored on a wall or when it is attached to furniture. It will be excellent.
[0020]
Then, for example, when opening the upper door, when the door opening / closing operator pulls the butting end face side of the upper door toward the front, the rail member on the upper side which has engaged the upper door via the traveling body, serves as a shaft support. It pivots forward with the upper door as a fulcrum. By this rotation, the upper rail member is inclined, and the rear rail of the upper rail member and the front rail of the lower rail member engaging the lower door are abutted and connected, and The butt end surface protrudes forward from the lower door. When the worker moves the upper door downward in this protruding state, the traveling body of the upper door travels on the rear rail of the upper rail member and then travels along the front rail of the lower rail member. The upper door can be arranged in parallel with the front of the lower door.
[0021]
In addition, since the lowering of the upper door is performed against the weight of the weight body, a sudden lowering of the upper door can be prevented and a safe lowering operation can be performed. This lowering of the upper door ensures that the upper half of the storage section is fully opened, making it possible to easily see the inside, and to quickly find the necessary storage items, and that there are no obstacles on the front. In addition, even if the storage items are horizontally long, they can be easily taken in and out without causing damage or the like.
[0022]
Next, when closing the upper door, the upper door is lifted up to the upper end while the traveling body of the upper door is running along the lower front rail and the upper rear rail sequentially in reverse to the opening. At the time of this lifting, the upper door rises with the aid of the falling weight of the weight, so that the operator can easily lift the upper door with a small force. Also, in this raised state, the upper door is still inclined, so when the butting end face side of the upper door is pressed toward the storage section, the rail member on the upper side rotates together with the upper door and is parallel to the axial direction. , Which enables a planar closure of the upper door.
[0023]
On the other hand, when the lower door is opened, the abutting end face side of the lower door is pulled forward, and the lower rail member is rotated in the forward direction together with the lower door. By this rotation, the rear rail of the lower rail member and the front rail of the upper rail member are abutted and connected. In this connection state, when the lower door having the traveling body engaged with the lower rear rail is moved upward, the traveling body travels along the upper front rail after passing through the rear rail. It can be arranged parallel to the front of the upper door, and the lower half of the storage section can be fully opened. Also, when the lower door is moved, the lower door can be easily lifted upward with a small force because it is assisted by the falling weight of the weight. In addition, due to the weight balance with the weight, the lower door and the upper door can be maintained in the raised state, preventing the lower door and the upper door from accidentally dropping during storage work. Safe work becomes possible.
[0024]
When the lower door is to be closed, the lower door is lowered to the lower end while the traveling body travels along the upper front rail and the lower rear rail in order, contrary to the opening of the lower door. Since this lowering is performed against the weight of the weight, it is possible to prevent the lower door from dropping abruptly and to perform a smooth lowering. Then, after the lower door is lowered, when the butting end surface side of the lower door is pressed toward the storage section, the lower rail member rotates together with the lower door and is arranged in parallel to the axial direction. Closing is possible.
[0025]
Since the present invention operates as described above, the entire long rail member is inclined in the present invention as compared with a product having a linear portion and a short and steeply inclined portion in the related art, so that the inclination angle is gentle. It is. As a result, troubles such as derailing of the traveling body are unlikely to occur, and a large shearing force is not applied to the traveling body and the rail members, so that the traveling body can travel smoothly, and as a result, the upper door and the lower door Easy opening and closing work becomes possible.
[0026]
In addition, since the upper half or the lower half of the storage section can be almost fully opened, it is easy to visually check the storage section and the stored article, and the storage article can be efficiently taken in and out. Further, the storage section can be fully opened in the width direction, and even a horizontally long storage item can be easily taken in and out. Further, it is possible to provide a hanging shelf, a drawer, a rack that moves back and forth, etc. in the storage unit to enable further effective use of the storage unit, and when the upper or lower door is opened, there is an obstacle in front. Since no objects are arranged, the drawer, rack and the like can be easily pulled out. In addition, since only the opening and closing space for the protruding distance when the upper or lower door is pulled forward is sufficient, it can be installed in a narrow space such as a parking lot or a corridor, and the upper or lower door with a wheelchair etc. Can be easily moved up and down.
[0027]
Further, the opening / closing device for a sliding door of the present invention has a simple structure including a frame on both sides, an upper door, a lower door, a rail member, vertical movement assisting means, etc., and does not require advanced fine adjustment and the like. It is possible to obtain a low-cost product that can be easily assembled. In addition, it can be installed not only indoors but also between entrance yards, parking lots, and other places. For example, when it is installed between the entrance yards, the entrance porch can also be used as the lower bottom of the storage section, so that steps can be eliminated and wheelchairs, strollers, etc. can be easily stored, and dirt such as kerosene tanks, shoes, etc. Can be stored, and cleaning can be easily performed.
[0028]
In addition, since the number of parts is small and the assembling property is excellent as described above, even if the assembling is performed at the installation site of the product, easy work is possible. However, the rail member and / or the vertical movement assisting means may be formed in advance so that they can be assembled to a substrate which can be fixed to the outer surfaces of the pair of side frames on the opening side. Then, if parts are assembled to the board in advance at a factory or the like and the board is fixed to both side frames, at the installation site, the both side frames are connected and fixed to a house or furniture, and the upper door and the lower door are engaged with the rail member. Installation work is completed only by combining. Therefore, the work efficiency of installing the slide door opening / closing device is improved, and it is also possible to prevent parts from being lost or forgotten when the product is transported to the installation site. Further, the board provided with the rail member and the vertical movement assisting means can be used by directly attaching it to a wall surface of a house or existing both side walls of furniture, and it is necessary to separately form both side frames for the present invention. Therefore, it is possible to obtain a low-cost and highly versatile product.
[0029]
Further, the rail member, as positioning means, a rail stabilizer plate that abuts the side surface on the rear rail side when the upper door or the lower door is closed, and the front rail side end of the rail member when the upper door or the lower door is opened. A rail positioning plate for abutting contact may be provided, and the rail member and the rail stabilizing plate may be rotatably connected via a fixed spring. And, by the spring force of the fixed spring, the rail member can maintain the contact state of the rail member with the rail stabilizing plate when the upper door or the lower door is closed. It does not rotate. When the upper door or the lower door is opened, the rail member is rotated against the spring force of the fixed spring to abut against the rail positioning plate, and the spring of the fixed spring exceeding the top dead center is reached. By force, the rail member can be kept in contact with the rail positioning plate, so that the rail member can be accidentally restored to the rail stabilizing plate direction even when the upper or lower door is opened. This makes it possible to smoothly move the upper or lower door up and down.
[0030]
In addition, if the upper door and the lower door are provided with handles at the upper and lower positions, respectively, it is easy to draw out each door in the front direction and to perform an up and down operation. In addition, by arranging a plurality of handles at any one of the upper and lower positions, it is possible to perform a vertical movement operation while holding the handles according to the position of the upper door or the lower door, and the operator can bend down greatly. This makes it easy for the elderly and wheelchair users to perform up-and-down movements.

An upper door (7) and a lower door (8) are arranged in the openings (6) of the pair of side frames (1) so as to be vertically movable. The lower end surface of the upper door (7) and the upper end surface of the lower door (8) are abutting end surfaces (10) that can abut against each other, and the abutting end surfaces (10) are located at the center of the opening (6). By abutting, the upper door (7) and the lower door (8) can be arranged on the same plane without a step. Further, the top plate (3) and the base plate (4) may not be separately provided for the present invention, and the ceiling or floor surface (29) of the house, the floor, etc. may be used as they are. Moreover, you may utilize the side wall of the house in which the opening / closing device of a sliding door is installed as both sides frame (1).
[0034]
Then, a pair of substrates (11) is fixed to the opening (6) side of the both side frames (1), and a pair of rail members (16) and (17) are attached to the substrate (11) in both upper and lower directions. It is axially supported and arranged coaxially. The pair of rail members (16) and (17) have a U-shaped cross section, and front rails (12) and (13) and rear rails (14) and (15) project in parallel with each other. 19) can be pivoted forward with the fulcrum as a fulcrum. When the upper door (7) and the lower door (8) are closed, they are arranged on the same straight line, and the front rails (12) (13) and the rear rail ( 14) and (15) are butt-connected. On the other hand, when the upper door (7) or the lower door (8) is opened, one or the other of the rail members (16) and (17) pivots toward the front via the shaft support portions (18) and (19), and the one or the other rail member is rotated forward. The rear rails (14) (15) and the other front rails (13) (12) can be butt-connected.
[0035]
Further, the rail members (16) and (17) serve as positioning means (37) for rotation when the upper door (7) or the lower door (8) is closed. A rail stabilizer (21) that can be contacted is fixed to the center of the substrate (11), and the rail members (16) and (17) are arranged in parallel in the axial direction by contacting the rail stabilizer (21).
