Abstract
PURPOSE: To easily and smoothly drag a ship up on the land by making the shape of its stern bottom changeable.
CONSTITUTION: Side plates 3, the lower edges of which are inclined are equipped at both sides of an inclined bottom 2 at a stern 1 and a pair of hollow supplementary bodies 4 of the wedge type are arranged at both sides of the bottom surface. A sharp angle end 4' of each hollow supplementary body 4 is pivoted with a hinge 6 to the horizontal bottom surface 5 adjacent to the inclined bottom surface and equipped so that a lever 7 stands on the bottom surface of each hollow supplementary body. As each lever is allowed to move up and down, the supplementary body 4 moves up and down, too, and when the supplementary body 4 is dragged up the body 4 is hidden between the side plates 3 and the shape of the bottom surface of this stern is suitable to land the ship on the incline. When the supplementary body moves down the state is show in the figure and the bottom surface of both supplementary bodies is on the nearly same plane as the bottom surface of the ship.
