摘要： A special-shaped folding umbrella which includes a plurality of 3-fold ribs and a plurality of 4-fold ribs is revealed. When the umbrella is closed, a height of a first connecting point of the 3-fold rib and that of a first connecting point of the 4-fold rib are quite similar (almost the same). A height of a sixth connecting point of the 3-fold rib is at similar to that of a seventh connecting point of the 4-fold rib. A third connecting point of the 3-fold rib and a fourth connecting point of the 4-fold rib are at similar height and so are a fourth connecting point of the 3-fold rib and a fifth connecting point of the 4-fold rib. A tip of the 3-fold rib and a tip of the 4-fold rib are maintained at similar level while the umbrella is closed.

摘要： A tip assembly of an umbrella is revealed. The tip assembly includes a tip rod detachably disposed on a distal end of an outer cylindrical rib of a rib and a protection piece arranged at a distal end of the tip rod. The tip rod is provided with a mounting hole for mounting the distal end of the outer cylindrical rib therein. The protection piece includes a curved outer surface and an inner surface opposite to the outer surface. The outer surface is abutting against respective support ends of a canopy, without exposed outside the canopy. The distal end of the tip rod is located at the inner surface of the protection piece to be protected thereon. Thereby the tip assembly will not have a sharp end or expose outside the canopy while the canopy is extended by the plurality of ribs.
