Description

Technical Field

[0001] This utility model relates to the field of outdoor products technology, and in particular to a foldable umbrella rib and a folding umbrella. Background Technology

[0002] The square pavilion, a classic outdoor sunshade and rain shelter, is widely used in parks, squares, courtyards, and commercial districts due to its sturdy structure and beautiful appearance. Its sunshade and rain shelter function is primarily achieved through the umbrella-rib structure supporting its canopy.

[0003] Currently, the common four-corner square umbrella frame structures on the market mainly fall into two categories: one is a fixed, integral structure, and the other is a structure with some folding functionality. The fixed, integral structure typically consists of a rigid frame composed of a single long pole or multiple non-movably connected long poles as its main ribs. While this structure offers good stability, its fixed and bulky size results in significant storage space requirements during off-seasons and requires substantial container space during transportation (especially in bulk shipments), leading to high logistics costs and imposing a considerable economic burden on manufacturers, distributors, and end-users.

[0004] To improve the convenience of storage and transportation, foldable umbrella rib structures have been developed in the prior art. These structures typically achieve folding by setting hinges or rotating joints between the umbrella rib segments. However, these existing folding structures still have significant shortcomings: First, their folding designs are often complex, with a large number of joints or cumbersome connection methods, resulting in high manufacturing costs; second, many folding structures have low folding efficiency, with only a limited reduction in the overall length of the umbrella ribs after folding, failing to significantly reduce packaging volume and resulting in little improvement in the economic benefits of transportation and storage; third, the locking mechanisms of some folding structures are unreliable, which may lead to wobbling or insufficient stability after the umbrella ribs are unfolded, affecting the overall safety and durability of the four-corner pavilion. Utility Model Content

[0005] This utility model aims to solve the technical problems in the prior art mentioned above, and proposes a foldable umbrella rib. The foldable umbrella rib adopts a multi-segment folding structure, wherein the foldable umbrella rib includes at least a first rod and a second rod, and the first rod and the second rod are connected by a folding joint.

[0008] Furthermore, the folding joint is a pin-type rotating structure.

[0009] Furthermore, the pin-type rotating structure includes a pin and a shaft hole. The pin is disposed on the first connecting member, and the shaft hole is located on the second connecting member. The first rod and the second rod are hinged together by the pin.

[0010] Furthermore, a folding umbrella composed of the aforementioned foldable umbrella ribs includes: four foldable umbrella ribs connected together at the same end to form a support frame for the folding umbrella when unfolded; and a support member connected to the end of the four foldable umbrella ribs connected together to support the support frame.

[0011] Furthermore, the support member includes a third rod and a fourth rod, which are nested together. The length of the support member can be changed by altering the relative positions of the third rod and the fourth rod.

[0012] Furthermore, the support includes fasteners for fixing the third rod and the fourth rod relative to each other.

[0013] Furthermore, the fastener is a spiral fastening mechanism, which is rotated to press the third or fourth rod to achieve fixation.

[0014] Furthermore, the third rod is provided with a positioning bead, and the fourth rod is provided with multiple positioning holes that cooperate with the positioning bead.
