ABSTRACT:
A frame for holding a body which lies thereon is pivoted on a transverse horizontal axis supported by a couple of vertical parallel uprights, on one of which a fixed electrical device having a rectilinear vertical stroke is provided. The remote controlled driver causes its push rod to move up and down, said push rod being connected with a slider that moves along the uprights.
A connection rod is hinged to the slider at one end, and to the frame at the other end, so as to cause the rotation of the frame through an arch in clockwise or counterclockwise direction, depending on slider motion direction.
