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.

The invention features a shade apparatus adapted to provide shade to an individual or individuals while they are outside and in need of shade from sunlight. Aspects of embodiments of the present invention contemplate a shade apparatus that is easily portable and easily adapted to the sun's changing positions, thereby providing the individual/user with shade from sunlight.

A calculus structure has a plurality of unit components and a plurality of joint components is provided. The unit components and the joint components are adapted to form a target structure. Each end of each of the joint components has an embedding construction or an embedded construction. Each of the unit components and the joint components has a bore therein for communication with each other. The bore is adapted to allow a cascading part to pass therethrough so that the unit components and the joint components are cascaded together by the cascading part, and the unit components and the joint components are movable relative to the cascading part so that the unit components and the joint components abut against each other in a cascading order to form the target structure.

A portable weather protection system is provided comprising a shaft with a handle at a first end of the shaft and a ring-like collar encircling the shaft and freely sliding a majority of a length of the shaft. The system also comprises a plurality of spokes attached in a hinge-like manner to a second end of the shaft and extending radially outward. The system also comprises a plurality of arms extending radially from the collar, each of the plurality supporting one of the plurality of spokes via leveraging mechanisms. The system also comprises a circular-shaped canopy attached at its center to the second end immediately above points at which the plurality of spokes attach to the second end, the canopy further attached at its edges to first ends of the spokes opposite second ends attached to the shaft.

A wind-resistant foldable umbrella includes a main shaft; a runner mounted around the main shaft and sliding between an opening position and a folding position; a first canopy and a second canopy with a central portion thereof fixed to the runner and the top end of the main shaft, respectively; a plurality of the umbrella ribs and a plurality of the pulling elements peripherally disposed around the main shaft and between the first canopy and the second canopy. Two ends of the pulling elements are connected to the corresponding umbrella rib and the runner, respectively. When the runner is at the opening position, the umbrella ribs expand toward the bottom end of the main shaft, so the first and the second canopy expand. Moreover, the umbrella ribs are pulled toward the main shaft by the resilient force from each pulling element.

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.

A reversible umbrella has a pole, a first handle affixed to a first end of the pole, a second handle affixed to a second end of the pole, and a plurality of ribs extending outwardly of the pole. A canopy is affixed to the ribs. The canopy has a first side facing one direction and a second side facing an opposite direction. The ribs are movable from a first position, wherein the first side of the canopy is in a generally concave configuration with respect to the first handle, to a second position, wherein the first side of the canopy is in a generally convex position with respect to the first handle. The opposing sides of the canopy preferably have different appearances or textures, such that the user can select between two designs to be exposed on the exterior of the umbrella.

An inversely foldable automatic umbrella includes a main shaft; an operating sleeve and a connecting sleeve mounted around the main shaft; a compression spring with two ends thereof contacting the connecting sleeve and the operating sleeve, respectively; a first canopy with a central portion thereof fixed to the operating sleeve; a second canopy with a central portion thereof fixed to the top end; a skeleton disposed between the first canopy and the second canopy; and a pull-moving mechanism having a sliding unit and a connecting unit. The sliding unit is slidingly disposed on the skeleton. Two ends of the connecting unit are pivotally disposed on the sliding unit and the operating sleeve, respectively. When the operating sleeve is at a folding position to fold up the first canopy and the second canopy, the skeleton is allowed to completely adhere to the main shaft.
