摘要
APPARATUS FOR LEARNING TO SWIM, WHICH CONSISTS OF: A SHAFT-SUPPORT WITH HANDLING MEANS FOR THE USER; FLOATING MEANS MOUNTED ON SUCH AXLE-SUPPORT; PROPELLING MEANS, OR SELF-PROPELLERS, COMMANDED BY THE USER, AND FOLDING MEANS, WHICH ALLOW USE AND TRANSPORT OR COLLECTION PROVISIONS. THE SHAFT-SUPPORT IS CONFIGURED IN CRANKSHAFT. THE MEANS OF FLOATING AND PROPULSION ARE, RESPECTIVELY, BODIES WHOSE RELATION BETWEEN THEIR DENSITY AND THAT OF THE WATER IS LESS THAN THE DENSITY, THE PROPELLERS MOUNTED FIXELY ON SUCH CRANKSHAFT AXLE WHEN THEY TURN THIS. THE FOLDING MEANS ARE A HINGE, THAT ARTICULATELY RELATES THE TWO PARTS OF THE AXIS-SUPPORT, TO POSITION THEM IN CONTINUITY -DEFLED- OR ADOSADILY -FOLD-. IT IS USED TO LEARN TO SWIM.
