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 reverse folding umbrella folds away from a user of the umbrella, thus reducing the likelihood that rain or other water on the primary fabric of the umbrella will fall onto the user while the umbrella is being folded and while the umbrella is in the closed position.

A hand-push rotating umbrella comprises extension springs at one side of the supporting ribs where an upward acting force can be produced by means of the pretension force of the extension spring when the moveable runner is pushed up so that the moveable runner and upper rib supporting rods would not fall down affected by gravity, thus a stable umbrella closing state able to be achieved without providing the engagement structure and solving the problems of the existing reversely-folded umbrella produced by only able to stably close the umbrella by using the engagement structure. Moreover, through the collocation application of the upper runner and moveable runner in the present invention, the umbrella canopy would rotate to offset the impact force caused by the wind resistance or collision in the case of strong wind or umbrella rib collision with some foreign object or person, thus able to avoid stabbing and hurting other people and improve the umbrella use safety.

The present invention relates to a portable shelter assembly. The assembly includes a support; and an expandable shelter for being supported by the support and expanding to shelter at least one person. The shelter includes ribs extending from the support. Each rib includes a proximal element pivotally mounted to the support. Each rib further includes a distal element extending from the proximal element and configured to move outwardly to expand the shelter when the proximal element pivots in a first direction. The ribs can be extended independently, one at a time.

An automatic reverse multi-folding umbrella includes a frame, an umbrella cloth secured on the frame, a middle rod set, an upper nest fixed to an upper end of the middle rod set, a lower nest fitted on the middle rod set, a handle, an umbrella opening/closing control system disposed in the middle rod set, and an umbrella opening/closing operating system disposed in the handle and the middle rod set. The umbrella can be folded and unfolded automatically. After the umbrella is folded, the umbrella cloth is folded reversely and the outer surface of the umbrella cloth is folded inside the umbrella, such that the umbrella can be used more conveniently, comfortably and quickly.

There is provided an umbrella (10, 110, 210, 310, 410, 510) moveable between an open position and a closed position, said umbrella comprising; a. a canopy framework (16, 18, 116, 118, 216, 218, 316, 318, 416, 418, 16, 518, 616, 618, 716, 718); b. a central spine (12, 112, 212, 312, 412, 512, 612, 712) configured to support the canopy framework; c. a main canopy (24, 124, 224, 324, 424, 524, 624, 724) configured to cover the canopy framework; and d. a tensioning mechanism 20, 22, 120, 122, 220, 222, 320, 322, 420, 422, 520, 522, 620, 62, 720, 722) configured to tension the main canopy about the canopy framework when the umbrella is in the open position and release the tension to the main canopy about the canopy framework to allow the umbrella to move to the closed position.

An automatic inversely foldable umbrella includes a skeleton structure provided with a main shaft; an upper runner fixed to one end of the main shaft; a lower runner slidably disposed on the main shaft; a middle runner slidably disposed on the main shaft between the upper runner and the lower runner; plural skeleton linkages having a first rib, a second rib, and a foldable rib; plural linking members with one end pivotally disposed on the lower runner and the other end connected with the first rib; a resilient member disposed between the middle runner and the lower runner, and compressible due to the middle runner and the lower runner movement; a first canopy combined to the upper runner and a second canopy combined to the lower runner for covering the skeleton linkages; and a handle. Therefore, the folding and expanding operation of the umbrella are facilitated.

A system for providing weather protection including shading in an automated and selective manner. The system includes an enclosure with an inner chamber and an outlet to the inner chamber. The system also includes a canopy and a deploy and retract assembly, which includes a canopy support assembly supporting the canopy. The deploy and retract assembly operates to move the canopy support assembly to move the canopy into the inner chamber and out of the inner chamber. The system further includes a controller generating control signals to operate the deploy and retract assembly. Specifically, this assembly is configured to retract the canopy by moving the canopy support assembly to move the canopy through the outlet into the inner chamber and further is configured to deploy the canopy by moving the canopy support assembly to move the canopy through the outlet to be at least partially outside of the inner chamber.

A wheelchair having, in an embodiment, a frame, a seat, a plurality of wheels and an umbrella assembly. The umbrella assembly has a canopy, a canopy holder and a driving device. During opening, the canopy slides upward through the canopy holder and extends outward.
