PCT No. PCT/IT96/00079 Sec. 371 Date Oct. 15, 1997 Sec. 102(e) Date Oct. 15, 1997 PCT Filed Apr. 22, 1996 PCT Pub. No. WO96/32991 PCT Pub. Date Oct. 24, 1996A device for rotating a body comprising a hollow member for grasping in a horizontal position; a constraint having three continuous portions, a first portion extending from a first end of the hollow member, a second portion extending through the hollow member, and a third portion extending from a second end of the hollow member; and a body attached to the first portion of the constraint. An operator oscillates the body in a pendular motion and sets the body in continuous revolution by abruptly pulling and releasing the third portion of the constraint to shorten and lengthen the first portion of the constraint. The third portion of the constraint is pulled when the body is moving below the horizontal plane and released when the body is moving above the horizontal plane. Continuous revolution is achieved by the constant pulling and releasing of the constraint. The body is preferably a ball, small aeroplane or rocket covered with a soft material wherein the device is used as a toy. |
