| CLAIMS What Is claimed: is: L A folding boat trailer with a drawbar having a proximal end to hold and carry the: trailer and a distal end ;to which a moving rear wheel assembly is attached,, with coupled wheels at the ends thereof, featuring attac ments between sections and retaining studs for such boat, wherein the frailer comprises: A T-shaped folding: support atsueh: distal end of the drawbar arm through which it is attached to suc rear ¾iheel assembly, suc drawbar distal end and its respective inner ends of both rear axle shafts of such moving rear wheel assembly of the drawbar being attached by articulated joints to such T- shaped folding support, each of those rear axle shafts being attached to on of the upper wings of the T in a folding way ttierearound, and such drawbar distal end also being attached in a folding wa to the arm of the T, At least one middle folding support located at a middle portion of the drawbar, At: least one retaiping. stud bn. each outer end of each of those axie shafts, Such drawbar forming, with such at least one T-shaped folding support, with such at least one middle folding support and such at least one retaining stud, a fully folding: trailer struetu , 2. Th folding trailer of claim 1 , wherein the wings and arms of the T of such at least one T-shaped folding support comprise U-shaped sections, and each ing and arm of the T has at least one lockifig bolt at its corresponding edge. 3. The folding trailer of plasm 1, wherein such at least one middle folding support comprises U-shaped cross section, coupled with the center of the: drawbar, where suetl: at least one; middle folding support includes at least distal ends are interconnected by means of at least one ax one rotating cylinder is coupled. SUPPLEMENTARY 'CLAIM 1. A folding.. boat trailer with a drawbar having a proximal end to hold and carry the trailer and a distal end to whic a moving rear wheel assembly is attached, with coopledi thereof, featuring attachments between sections and retaining studs for such boat, wherein the trailer comprises: A T-shaped folding support at such distal end of the drawbar arm through which it is attached to, such, rear wheel assembly, such drawbar distal end and its respective inner ends of both rear axle shafts of such moving rear wheel assembly of the drawbar being attached by articulated joints to such T- shaped folding support, each of those rear ax!e shafts being attached to one of the upper wings of the T in a folding way therearound, and such drawbar distal end also being attached i a folding way to the arm of the T, At least a middle folding support located at a middle portion of the drawbar, At least a retaining stud on each outer end of each of those axle shafts, Such drawbar forming, with such at least one T-shaped folding support, with such at least one middle folding support and such at feast one retaining stud, a fully folding trailer structuie. em: li0 : ¾Q;:G|aimsi: |
