1. the secondary leakage-proof umbrella of this invention is primarily directed to the improvement that the adjacent triangular plate suture leakage problems of umbrella surface carries out, to there being two big class umbrellas:

  • First kind secondary leakage-proof umbrella;

    adopt the secondary leakage-proof umbrella of protecting tube design;

    Refer to Fig. 5, Fig. 6 in Figure of description;

    the secondary leakproof single layer umbrella of one of secondary leakage-proof umbrella adopting protecting tube (mozzle) to design;

    Fig. 5;

    secondary leakproof single layer umbrella (inner side);

    Fig. 6;

    the mozzle on inside umbrella cover;

    If changed into 2 layers (or multilamellars) by the monolayer umbrella cover of the single layer umbrella of secondary leakproof above, corresponding be exactly;

    adopt secondary leakproof bilayer (or multilamellar) umbrella of protecting tube design;

    Therefore, no matter umbrella cover has how many layers, here it is important that adopt protecting tube (mozzle or cry anti-fistulae, gap, the inside be leakage-proof socket) as the design of secondary leakproof, the umbrella of this design is all " the secondary leakage-proof umbrella adopting protecting tube design ", and this design of this umbrella, manufacture method are required for being protected;

    Equations of The Second Kind secondary leakage-proof umbrella;

    adopt the secondary leakproof double-layer umbrella of double-deck independent rainproof umbrella cover design, wherein have it is important that;

    internal layer umbrella cover triangular plate suture is independent, separate with outer layer umbrella cover triangular plate suture, this is crucial, this design needs protection, such as, if when three layers umbrella occurs, every layer of triangular plate suture is all each independent, so the rainproof effect of 2 layers, the inside stacks up and also the seepage of outer layer umbrella cover suture can be played protective action, as long as the adjacent triangular plate of internal layer umbrella cover have employed independent stitching, have employed the stitching separated with outer umbrella cover, this design also belongs to this design, please protect.
