An umbrella assembly is provided that includes a frame, a canopy, an extension and a base. The frame includes a post and top piece, a number of arms, a number of connectors, a lift ring and a locking pin. The post includes a number of rod members attached together in adjacent parallel space orientation with a top piece which rotatably attaches to each of a number of arms each arm having a number of arm rod members attached together in adjacent parallel space orientation. Each arm is rotatably attached to one end of a connector. The other end of each connector is rotatably attached to the lift ring. Raising and lowering the lift ring opens and closes the umbrella arms. The locking pin holds the lift ring in an upper position.

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 umbrella includes an anti-inversion mechanism that is configured to apply to each rib assembly a force that counters an inversion force that is applied to the umbrella. The anti-inversion mechanism includes a flexible elongated structure that is disposed exteriorly along the second rib part and has a first bent end that is attached to the second rib part by passing through an opening formed in the second rib part and being anchored within a hollow interior of the second rib part. The mechanism further includes a flexible wire having a first end attached to the flexible elongated structure of the anti-inversion mechanism and a second end attached to a rib tip that is located at a free distal end of the rib assembly.

A cantilever umbrella, including umbrella cloth, an umbrella rod, a top notch with a guide sleeve, a runner, umbrella ribs and stretchers is disclosed. The umbrella rod contains an inner section and a cantilever section; the umbrella rob passes through the guide sleeve and the top notch in sequence with the end of the inner section hinged to the runner. The cantilever section can be extracted from the guide sleeve to open the umbrella ribs and stretch the umbrella cloth into place. The cantilever section can be moved laterally and fixed into position at the end of the guide sleeve to stabilize the open state of the umbrella ribs.

An arthritic-aiding pin-centering-and-guiding auditorily-snap-locking umbrella comprising: a canopy having tension-adjusting oval openings, a pole having a fixed hub and a movable hub, tension-adjusting rods, rod-locking screws respectively screwed through the tension-adjusting oval openings and into the tension-adjusting rod, three pulleys respectively screwed to the fixed hub and the movable hub, a pulley cord threaded on the three pulleys and attached to the movable hub, a cord hook, two gear cams attached to the movable hub, a cord blocker attached to the two gear cams, at least one pin opening drilled through the pole, an arthritic-aiding grip ring attached to the cord hook, a locking pin attached to the arthritic-aiding grip ring, a recess molded on the locking pin, at least one pin-centering-and-guiding plug and tube having built-in auditorily-snap-locking leaf springs and leaf-spring towers inserted into the pole and aligned with the at least one pin opening, and a tower-locking screw screwed between the leaf-spring towers for locking the plug inside the pole.

An adjustable non-view obscuring umbrella having a canopy and a support structure. The support structure having a support post, a plurality of non-articulating umbrella ribs, and at least one articulating umbrella rib. An articulating umbrella rib having an upper rib member, a lower rib member, and an umbrella rib articulation mechanism. An umbrella rib articulation mechanism having an upper bracket and a rotation actuation member, wherein the rotation actuation member is rotationally coupled to the upper bracket
