An umbrella tip structure for vertical placement of an umbrella is disclosed, including a fixed pillar, a movable barrel, a spring, and at least two tip blades. The umbrella tip structure is mountable to an umbrella in such a way that tip blades can be automatically expanded and/or collapsed so that in use, with a movable barrel positioned against a horizontal surface, the tip blades may be opened automatically to make the umbrella tip structure a stable and firm support stand that stably and firmly supports the umbrella in a vertical, upright condition on a horizontal surface, achieving vertical placement of the umbrella. The operation and use of the umbrella tip structure is simple and easy.

A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable.

Disclosed is an improved pull rib structure of a wind-resistant umbrella. The pull rib includes a rigid pull bar section and a flexible pull wire connected to each other. The pull wire has a free end that is coupled through a tighten-up device to the outer rib. The tighten-up device includes a position-restoration member arranged therein to connect to the free end of the pull wire and apply a position-restoration driving force to the pull wire. The tighten-up device keeps the pull wire in a stretched and tight condition during collapsing of umbrella so as to prevent entangling and ensure a smooth opening operation and service life of the umbrella.

A solar charging umbrella uses solar power to charge electronic devices wirelessly, such as by a wireless or inductive charging port. The umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella's battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of higher power devices such as tablet computers.

A wind resistant umbrella includes an upper canopy that is attached to a lower canopy at select points. Elastic fasteners (e.g., elastic straps) elastically connect the upper canopy to the lower canopy. Flexible connectors that wrap around a peripheral edge of the lower canopy serve to both fixedly attach first ends of the elastic fasteners and provide pockets that receive free ends of the ribs to securely attach the ribs to the lower canopy.
