DITCH COVER HOLDER AND METHOD FOR LIFTING DITCH COVER
To ensure that even heavy ditch covers can be easily lifted.SOLUTION: There is provided a ditch cover holder 100 for holding a ditch cover 1 with a through hole 2 opened, including a pair of tilting pairs 10 that are pivotally supported around a rotating shaft 11, a flange 20 provided at one end of each of the pair of tilting pairs 10, which is larger in outer diameter than the tip portion of the tilting pair 10, and a grip portion 12 provided on the other end side of each of the pair of tilting pairs 10. The flange 20 is formed in a size that allows the pair of tilting pairs 10 to be inserted into the through hole 2 of the ditch cover 1 in a closed posture in which the pair of tilting pairs 10 are tilted around the rotating shaft 11, abuts a tip 13 of the tilting pair 10 on the inner surface of the through hole 2 of the ditch cover 1 in an expanded posture in which the tilting pair 10 is inserted into the through hole 2 and tilted around the rotation axis, and is configured to be able to support the ditch cover 1 with the back of the flange 20 connected to the tip 13 of the tilting pair 10.SELECTED DRAWING: Figure 6
【課題】重量のある溝蓋でも、引き上げを容易に行えるようにする。【解決手段】貫通孔２の開口された溝蓋１を保持するための溝蓋保持具１００であって、回動軸１１を中心に傾動自在に軸支された一対の傾動対１０と、一対の傾動対１０の各々について、一端側に設けられた、該傾動対１０の先端部分よりも外径を大きくした鍔部２０と、一対の傾動対１０の各々について、他端側に設けられた握り部１２とを備え、鍔部２０は、一対の傾動対１０を、回動軸１１を中心に傾動させて閉じた閉塞姿勢において、溝蓋１の貫通孔２に挿通可能な大きさに形成されており、貫通孔２に傾動対１０を挿入した姿勢で、回動軸を中心に傾動させて拡開した拡開姿勢において、溝蓋１の貫通孔２の内面に傾動対１０の先端１３を当接させ、かつ該傾動対１０の先端１３と連結された鍔部２０の背面でもって、溝蓋１を支承可能に構成される。【選択図】図６
