An umbrella includes an umbrella column having a top portion hingedly fitted with one end of a connecting rod, and the other end of the connecting rod is hingedly fitted with a pull rod. One side of the umbrella column has a chute, an armrest shell is slidably fitted in the chute, one end of the pull rod is hingedly fitted with an upper umbrella tray, and the other end of the pull rod is fixedly connected to a handle base. The rope reel set is used to wind an umbrella rope, and extends into an umbrella tray assembly along the pull rod. The handle base is hingedly fitted with the armrest shell located at an inner side of the umbrella column and provided for fitting with the chute. The armrest shell is movably positioned along the chute.

Disclosed are example embodiments of a cantilever-canopy umbrella. An example may be a five-device-in-one physically-impaired-assisting easy-slide-and-lift dog-run-adaptable land-yacht-adaptable projector-screen-adaptable anti-wobbling foot-pedal-operated robot-assembled cantilever-canopy umbrella. An example embodiment may be rotatable-floating-table-locking rotatable-floating-chair-locking rotatable-umbrella-locking foot-pedal. The example embodiment may include a 360-degree-locking disk. The example embodiment may also include a plurality of umbrella-pole-locking four-wall tunnels. The example embodiment may also include a noise-cancelling tunnel-and-disk-protecting housing. The example embodiment may also include a noise-cancelling tunnel-and-disk-protecting flange slid over said noise-cancelling tunnel-and-disk-protecting housing. The example embodiment may include a multi-height-adjustable easy-slide-and-lift 360-degree-rotatable canopy-supporting vertical mast secured to said 360-degree-rotatable noise-cancelling rotatable-floating-table-adaptable rotatable-floating-chair-adaptable pole-supporting vertebrae. The example embodiment may also include a plurality of multi-height-adjustable holes drilled into said multi-height-adjustable easy-slide-and-lift 360-degree-rotatable canopy-supporting vertical mast. The example embodiment may include a rain-blocking top-strut-lifting weather cap secured to said multi-height-adjustable easy-slide-and-lift 360-degree-rotatable canopy-supporting vertical mast.

The above ground solid pool cover is the only product of its kind that is exceptionally crafted with mechanisms that support pool cover removal and placement all while guaranteeing that little to no debris comes into contact with the pool water. This unprecedented product is uniquely designed with a lighter and more resistant material than any other average pool cover to ensure users are able to easily maneuver, store, and clean the cover for efficient maintenance.

An umbrella assembly is described in which a spring assisted movement of a knob away from or toward an umbrella handle respectively deploys or retracts a canopy and a plurality of support ribs. In the deployed position, each rib curves and keeps the canopy under tension. Elastic potential energy of a spring located within a body interior space deploys or retracts the ribs and canopy out of or into the body interior space, respectively.

An umbrella assembly with a drive module assembly that comprises a plurality of modularized units, including a separate power supply unit and a separate drive unit. The modularized units are removably/detachably attached in a stacked structure of the overall drive module using quick connect couplings. The interfacing top and bottom sides of the adjacent modularized units are provided with complementary electrical connection terminals. The drive module is structurally and operatively coupled to the frame structure of the canopy of the umbrella assembly to operate to open/extend or close/collapse the canopy between an opened configuration and a closed configuration, by varying the distance between the upper hub and the lower hub of the frame structure.

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.
