Disclosed herein are retractable umbrella frame devices comprising a base body structure at least partially surrounding a central axis structure. The central axis structure can be connected to a skeletal frame structure comprising a plurality of arms having a first end connected to the central axis structure and a second free end. The plurality of arms can be moveably connected to the central axis structure, such that the arms can be retracted into or extended from the base body structure. In some embodiments, the base body structure comprises open portions along its length. In some embodiments, the retractable umbrella frame devices further comprise one or more secondary support structures at least partially surrounding the base body structure. In some embodiments, the retractable umbrella frame devices can further comprise guide structures connected to the one or more secondary support structures and the arms of the skeletal frame structure.

A portable shelter includes a frame structure with a plurality of pole structures. In some embodiments, a pole structure includes telescopically movable pole portions and a spring-biasing mechanism configured to bias one pole portion away from the other. In some embodiments, a center hub structure of the portable shelter includes a locking mechanism for engaging one of the pole portions to interfere with telescopic movement of the pole structure. In some embodiments, a pole structure includes a flexible portion attached to a first rigid portion, and a second rigid portion that is movable relative to the first rigid portion. The second rigid portion is pivotable or telescopically movable between a first position in which the second rigid portion overlaps the first rigid portion such that the flexible portion is free to flex, and a second position in which the second rigid portion overlaps and restrains the flexible portion.

In a locking system for a rotating foot of a mast, particularly of a mast for a free arm standing parasol, the mast is rotatable about an axis of rotation (A) defined by the rotating foot and includes a surrounded mast region. The locking system includes an operating lever for releasing or locking of the rotating foot which is arranged on the mast at a comfort height (H) of 0.5 to 1.5 m above the rotating foot, wherein the operating lever is movable between a folded-out position and a downwardly folded-in position and thereby cooperates via a lifting bar with stationary engaging elements of the rotating foot, wherein the lifting bar is raised in the release position and lowered in the locking position. To improve operability and operational security, the lifting bar is arranged at a distance from the axis of rotation (A) and externally of the surrounded mast region.

A straight-pole sun umbrella hand-cranking device comprises a standing pole and a shell fixed on the standing pole, wherein the shell comprises a first outer shell and a second outer shell. The shell is fixed on one side of the standing pole, and a rope winding wheel is mounted within the first and the second outer shells. The rope winding wheel is connected to a cranking shaft, and the cranking shaft is propelled to rotate through a cranking handle connected with the cranking shaft. An anti-slip mechanism is arranged on the cranking shaft. The anti-slip mechanism comprises a torsion spring, the torsion spring is sleeved on the cranking shaft. The rope winding wheel achieves easy winding or unwinding of the ropes, and the anti-slip performance is improved by the elastic force of the spring. As the aforesaid structure is protected against abrasion, its functional life is significantly prolonged.

An outdoor umbrella includes an umbrella post, an umbrella cover assembly and a folding-unfolding device. The umbrella cover assembly includes an umbrella rib assembly and an umbrella fabric covering the umbrella rib assembly. The folding-unfolding device includes a slide sleeve, a folding-unfolding handle assembly and a pull rod. A first oblique rod and a second oblique rod hinged and matched with each other are disposed on the umbrella rib assembly. One end of the first oblique rod is hinged to the slide sleeve. One end of the second oblique rod is hinged and matched with the umbrella post. A middle portion of the folding-unfolding handle assembly is hinged and matched with the umbrella post, and the folding-unfolding handle assembly is able to vertically stretch the pull rod in cooperation with a lever and drives the slide sleeve to slide vertically to fold or unfold the umbrella cover assembly.

An electronic umbrella is provided. The device includes a housing having a fastener disposed on a lower surface thereof. A motor is disposed within the housing, wherein the motor is operably connected to a power source disposed within the housing. A rod is affixed to an upper surface of the housing.
