Patent ID: 11857041

Abstract:
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.
