ROTARY GRIP DEVICE FOR FLOOR OPENING LID
To provide a rotary grip device for a floor opening lid capable of allowing dementia patients and infants not to perform the opening and closing operations of a lid, and not to freely move a rotary grip of the rotary grip device.SOLUTION: The rotary grip device for a floor opening lid comprises an operation pivot 3, a locking pivot 4, and a wave washer 6. The operation pivot 3 is provided in a frame body 1 rotatably. The locking pivot 4 is fastened to the operation pivot 3 with a screw 8 so as not to rotate relatively, and is provided with a locking piece 41 that prevents a rotary grip 2 from being operated rotationally by means of contact of protrusion 23 formed on the rotary grip 2, which is stored within the frame body 1. The wave washer 6 provides rotational resistance having a predetermined magnitude for the operation pivot 3 by fastening the operation pivot 3 and the locking pivot 4.SELECTED DRAWING: Figure 3
【課題】認知症患者や乳幼児が、蓋体の開閉操作や回転把手装置の回転把手の動作を自由に行うことができないようにすることができる床開口蓋体用回転把手装置を提供すること。【解決手段】枠体１に回転可能に設けられる操作軸３と、この操作軸３にビス８によって相対的に回転しないように締結され、枠体１内に格納されている回転把手２に形成された突片２３が当接することで回転把手２が回動操作されることを防止する係止片４１を形成したロック軸４と、操作軸３とロック軸４とを締結することで操作軸３に所定の大きさの回転抵抗を付与するウェーブワッシャ６とを備える。【選択図】図３
