COVER OPENING ADAPTOR
PROBLEM TO BE SOLVED: To provide a cover opening adaptor that is an auxiliary jig for opening a cover, the cover opening adaptor allowing an ordinary cover opening bar to be used even when an engaging hole for cover opening does not open along a peripheral edge of a cover body, offering greater cover opening force than when opening by inserting the bar into an engaging hole for cover opening formed on the cover body, being compact, light-weight, of a simple configuration and manufactured readily at a low cost.SOLUTION: A cover opening adaptor 100 includes: an adaptor body 110 having a protrusion 111 formed on an undersurface side, the protrusion having a point of application 111a in contact with a tip part of a bar 300 for cover opening; a plurality of contacting members 120 supporting the adaptor body 110 in a way that allows height adjustment and being in contact with a cover body 210 of a cover for an underground structure; a fulcrum member 130 having a fulcrum part 132 in contact with the bar 300 and a groove part that holds the protrusion 111 of the adaptor body movably only in a vertical direction; and an engaging pin 140 inserted into an opening 112 of the adaptor body from above and having an engaging part engaged on an undersurface of an engaging hole part 211 for cover opening of a cover body.SELECTED DRAWING: Figure 1
【課題】蓋本体の周縁に開口していない開蓋用の係合孔の場合であっても通常の開蓋用のバールを使用することができ、当該バールを蓋本体の開蓋用の係合孔に差し込み開蓋するよりも大きな開蓋力が得られ、小型かつ軽量で、しかも簡単な構成であって容易かつ安価に製造可能な開蓋用の補助治具である、開蓋アダプタを提供すること。【解決手段】下面側に開蓋用のバール３００の先端部と当接する作用点部１１１ａを有する突出部１１１を設けたアダプタ本体１１０と、アダプタ本体１１０を高さ調節自在に支持し、かつ地下構造物用蓋の蓋本体２１０と当接する複数の当接部材１２０と、バール３００と当接する支点部１３２、およびアダプタ本体の突出部１１１を上下方向にのみ移動可能に保持する溝部を有する支点部材１３０と、アダプタ本体の開口部１１２の上方より挿通され、かつ蓋本体の開蓋用の係合孔部２１１の下面に係合する係合部を有する係合ピン１４０とを組み合わせてなる開蓋アダプタ１００。【選択図】図１
