Description

Technical Field

[0001] This invention relates to an umbrella, specifically a sun umbrella that is easy and quick to assemble. Background Technology

[0002] Sun umbrellas, as an outdoor leisure tool, are widely used in squares, beaches, parks, and courtyards, providing people with comfortable shade. Existing sun umbrellas generally consist of an umbrella pole, an umbrella frame, and an umbrella fabric. The umbrella frame is connected to the top of the umbrella pole, which primarily supports it. The umbrella fabric is connected to the frame; when the frame is opened, the fabric also opens, allowing the sun umbrella to be used. The umbrella frame includes an upper rib, a lower rib, long ribs, and short ribs. The upper rib is fixed to the top of the umbrella pole, while the lower rib is movably mounted on the pole. The upper ends of the long ribs are attached to the upper rib, and the lower ends of the short ribs are attached to the lower rib. The upper ends of the short ribs are hinged to the middle of the long ribs. In existing structures, the connection between the ribs and the ribs usually involves the rib having a groove for fixing the rib. The rib connects to this groove and is secured with wire. This installation structure is complex, inefficient, and inconvenient to replace if one rib is damaged.

[0003] An investigation revealed that the existing Chinese patent CN201020107572, entitled "Connection Structure of Umbrella Nest and Umbrella Rib," is characterized by a gear-shaped groove for nesting and fixing the umbrella rib. The groove's gear-shaped segments have protruding protrusions on both sides to nest the umbrella rib connecting rod. The umbrella rib connecting rod has a side-opening groove on each side of its head, approximately equal to the height of the protrusion. This connection structure allows for a rotatable connection between the umbrella nest and the umbrella rib, facilitating production, installation, and dismantling. However, it is limited to the connection between the umbrella nest and the umbrella rib, without improving the assembly of the umbrella nest and the umbrella rod. Furthermore, while quick assembly of the umbrella rib and umbrella nest is possible, the connection is not stable enough, and the umbrella rib is prone to detachment. Summary of the Invention
