The presently disclosed subject matter is directed to a sun shade assembly. Particularly, the assembly includes a sail that releasably attaches to a pair of ribs, providing shade to the user. At least one support arm can be used to reinforce the ribs. A mast provides height to the assembly and includes an anchor that allows the assembly to be secured into a support surface (e.g., sand). The ribs and support arms rotate about the mast, thereby self-adjusting the direction of sail in response to the wind blowing. The assembly further includes a tension adjuster that can be tightened or loosed to control the rotation of the ribs and support arms in response to wind conditions.

An umbrella including a support shaft, a plurality of ribs, a rotatable cam assembly, and a canopy. Each rib of the plurality of ribs has a proximal end portion and a distal end portion. The proximal end portion is pivotably attached to an upper portion of the support shaft to pivot the rib between an open position and a closed position. The rotatable cam assembly includes a cam configured to rotate about a longitudinal axis of the support shaft. The cam is engaged with each rib of the plurality of ribs such that (i) each rib moves in a direction from the closed position to the open position when the cam rotates in a first direction and (ii) each rib moves in a direction from the open position to the closed position when the cam rotates in a second direction, the second direction being opposite the first direction.

The disclosure is directed at an umbrella including a canopy having a set of canopy portions; and a frame portion comprising a shaft portion; a sliding collar assembly coupled to the shaft portion and sliding along the shaft portion; and a set of ribs, each of the independent ribs attached to one of the set of canopy portions and to the sliding collar assembly, where each of the set of ribs move independently of each other when a high wind force is experienced by one of the canopy portions.

A mount for a shade structure, in particular a collapsible pavilion. The mount has a base and a cover. The base has a space formed therein configured to receive a ground support of a shade structure. The cover has a top surface and a bottom surface to be secured to the base. A groove is formed in the mount and is configured to pivotably receive a rib. The groove is disposed between opposed walls of the mount. A pin retention recess is disposed on each side of the opposed walls in one of the cover and the base. A plurality of projections are provided that each have a first end fixed to one of the cover and the base in which the pin retention recess is not formed and a second end disposed away from the fixed end. One of the projections is configured to enclose a portion of the retention recess when the cover and the base are secured together.

A wind-lift-eliminating self-adjusting self-stabilizing arthritic-aiding umbrella comprises: a flow-directing chapeau attached to a chapeau crown, an upper cone rotatably attached to a cable conduit for preventing the umbrella from radially twisting clockwise and counterclockwise out of shape, a lower tube for centering the upper cone, a stanchion, an intersector bolted to the stanchion, a supporting-arm intersector, a top-hub, a canopy-height-and-tilt-adjusting arthritic-hand-aiding handle slidably connected to the stanchion, a height-adjusting arthritic-hand-aiding trigger springably and pivotably attached to the handle for providing aid to arthritic hands to operate the handle without discomfort and for providing means to slidably lower and raise the handle to adjust the umbrella, a supporting arm pivotably attached to the lifting-arm intersector and the supporting-arm intersector, a lifting arm pivotably attached to the handle and the top-hub intersector, the supporting-arm intersector pivotably attached to the lifting arm, a deploying cable, a cable spool molded into the handle and attached to the cable, an arthritic-hand-aiding crank, an arthritic-hand-aiding-crank paddle rotatably connected to the crank for providing aid to arthritic hands to operate the crank providing means to deploy and retract the umbrella without discomfort, a reversible wind-pressure-releasing and cooling-funnel canopy for providing a cover to protect users from weather elements and for releasing air pressure below the umbrella, an opening is cut into the canopy, a top-hub-ring, the cable conduit rotatably attached to the top-hub-ring, the top-hub intersector pivotably attached to the top-hub-ring, a bottom-shuttle-hub-ring, the lower cone rotatably attached to the bottom-shuttle-hub-ring, the cable connected to the bottom hub-ring, upper-ribs, wind-lift-eliminating self-adjusting funnel-and-canopy-tension-adjusting springs for adjustably tensioning the canopy and for customizingly relieving air pressure below the umbrella to stabilize and to eliminate lift and vibration from wind gusts, adjustable-tension-canopy-spring brackets springably securing the wind-lift-eliminating self-adjusting funnel-and-canopy-tension-adjusting springs to the upper-ribs, lower-ribs pivotably screwed to the bottom-shuttle-hub-ring and the upper-ribs, a stanchion base-mounting plate attached to the stanchion, and base-stabilizing feet bolted to the base-mounting-plate.

Disclosed herein is a large umbrella configured to solve several existing deficiencies. The umbrella is configured for ease of operation, requiring very little effort for operation. This is achieved, in part, by use of a specially designed actuator arm used in conjunction with at least one pulley and counterbalanced weight system. Moreover, the umbrella canopy and framework is configured to allow the entire canopy to be lowered while remaining fully extended, so as to form a cover for a table into which its center pole is situated. Additionally, the umbrella canopy can be constructed with an extendible skirt. When unfurled, the skirt can extend the canopy cover so as to form an enclosure that fully surrounds the table, table legs, and chairs, for example.
