求項１に記載の水上ヘリポート。[Scope of Claim for Utility Model Registration] (1) An upper float on which the helipad main body is formed with a helicopter takeoff and landing deck, a lower float positioned parallel to the upper float at a predetermined distance, and these a support column interposed between the floats, and a weight connected to the heliport body so as to extend freely from the support column, and when the weight of the weight acts on the heliport body, the water surface is at the position of the upper float. A water helipad, characterized in that the weight and volume of the helipad body and the weight are set in relation to buoyancy so that the water surface is at the position of the support pillar when the weight of the weight does not act on the helipad body. (2) The water helipad according to claim 1, wherein a plurality of freely windable chain weights are evenly arranged on the helipad main body.
