Description

【０００１】
【発明の属する技術分野】
本発明は連絡通路装置に関するものである。
【０００２】
【従来の技術】
陸上と岸壁に停泊中の船舶の間の相互通行手段には、船舶の様式、その喫水、及び停泊水域の潮汐などの諸条件に起因する陸上と船舶の相対的な高低差に対応可能な連絡通路装置が用いられている。
【０００３】
図６は従来の連絡通路装置の一例であり、この連絡通路装置は、岸壁側に配置される階段状の移動台１と、基端部が通路幅方向に水平に延びるピン２によって移動台１に設けたブラケット３に枢支されたフレーム４と、該フレーム４の先端部にピン２と平行なピン５により枢支されたプラットホーム６と、通路長手方向に等間隔に配置した複数のステップ７と、該ステップ７のそれぞれをフレーム４に前後へ傾動可能に枢支する支持軸８と、フレーム４下方に平行に配置した連動部材９と、各ステップ７から下方へ突出し且つそれぞれピン２と平行な連動ピン１０によって連動部材９に連結したブラケット１１と、フレーム４下方に平行に配置したシリンダ１２とを備え、フレーム４、連動部材９、ステップ７、並びにブラケット１１によって、平行四辺形リンクを形成している。
【０００４】
連動部材９の基端部は、ブラケット３下方に位置するように移動台１に設けたブラケット１３に、ピン２と平行にピン１４により連結され、ステップ７の上面がフレーム４の起伏の影響を受けることなく常時水平を保持できるようになっている。
【０００５】
連動部材９の先端部は、プラットホーム６から下方へ突出するブラケット１５に、ピン２と平行なピン１６により連結され、プラットホーム６がステップ７に同調して前後へ傾動し、プラットホーム６の上面がフレーム４の起伏の影響を受けることなく常時水平を保持できるようになっている。
【０００６】
シリンダ１２のハウジングは、ブラケット１３下方に位置するように移動台１に設けたブラケット１７に、また、シリンダ１２のピストンロッドは、フレーム４から下方へ突出するブラケット１８に、それぞれピン２と平行なピン１９，２０により連結されている。
【０００７】
更に、移動台１には、岸壁の上面を転動可能なローラ２１が枢支され、また、移動台１、フレーム４、並びにプラットホーム６の左右両側には、転落防止用の柵（図示せず）が取り付けられている。
【０００８】
図６に示す連絡通路装置では、シリンダ１２の作動によって、ステップ７及びプラットホーム６の上面が水平を保持した状態でフレーム４が起伏し、プラットホーム６の上下方向の位置が変化する。
【０００９】
すなわち、シリンダ１２のハウジングに対するピストンロッドの突出量を増加させると、プラットホーム６と移動台１の高低差が拡大し、また、シリンダ１２のハウジングに対するピストンロッドの突出量を減少させると、プラットホーム６と移動台１の高低差が縮小する。
【００１０】
【発明が解決しようとする課題】
しかしながら、図６に示す連絡通路装置においては、フレーム４が水平な状態以外は、フレーム４の傾斜角度が緩やかな場合であっても、複数のステップ７の上面が階段状に並ぶ状態を呈し、これに加えて、フレーム４を枢支する移動台１が階段状であるため、階段歩行が困難な高齢者や車椅子利用者などの通行には、介添者の支援を必要とし、また、貨物運搬台車、キャスタ付スーツケースなどを走行移動させることもできなかった。
【００１１】
本発明は上述した実情に鑑みてなしたもので、高低差が変化する２地点の間を容易に相互通行できる連絡通路装置を提供することを目的としている。
