An umbrella is provided that includes a hollow pole, a shade assembly, a counterweight system, and a locking device. The shade assembly includes a guide rod coupled with an upper hub. The guide rod has a stop surface. The counterweight system has a ballast and a cord that has a first end coupled with the ballast and a second end coupled with a lower hub. The locking device has pushrod mechanism. When closing the umbrella, the pushrod mechanism moves upward disengaging a moveable locking surface from the guide rod to allow the lower hub to move downward and the ballast to move upward.

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.

Disclosed is an umbrella that can be used as a canopy to protect a user against rain or sunlight. The umbrella may comprise an elongate member having proximal and distal end portions, a support structure that is connectable to a canopy able to be disposed about the distal end portion of the elongate member, the support structure being be adjustable between an erect position, whereby the canopy is able to be tensioned by the support structure, and a collapsed position, whereby the tension in the canopy is able to be released. The umbrella may also include a plurality of biasing means configured to inhibit the support structure from inverting.

A hand-push umbrella comprises a column (1), an upper nest (2) movably disposed at the top of the column (1), a lower nest (3) movably sleeved on the column (1), a plurality of long rods (10) having an upper end mounted on the upper nest (2) and a plurality of first short rods (20) having a lower end mounted on the lower nest (3) and an upper end hinged to the middle portion of the long rod (10); a first retainer ring (4) is sleeved on the column (1) above the lower nest (3) and is fixed with the column (1), a handle (8) is connected to the bottom of the lower nest (3), a handle control mechanism is disposed inside the lower nest (3). The umbrella is simple and reasonable in structure, and can be easily and fast unfolded and folded. A tray (7) and a plurality of second short stretchers (30) greatly strengthen the support to the canopy (100) and improve the stability of the structure.

An umbrella is provided that includes a hollow pole, a shade assembly, and a lift assembly. The shade assembly is coupled with an upper portion of the hollow pole. The shade assembly includes an upper hub, a lower hub, and a shade structure coupling the upper hub to the lower hub. The shade structure supports a shade member and the lower hub is moveable along the hollow pole. The lift assembly is disposed within the hollow pole. The lift assembly includes a gas spring and a cord. The cord has a first end coupled with the hollow pole and a second end coupled with the lower hub. When closing the umbrella, the cord applies a load to compress the gas spring. When opening the umbrella, the gas spring applies a load to the cord, to cause the lower hub to be moved upward.
