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.

A cantilever umbrella has an upstanding mast and a cantilever arm adapted to support a canopy. The mast has an interior region defined by a longitudinally extending channel with a longitudinally aligned opening extending from the interior to the exterior of the mast. A carriage resides within the channel and is adapted for travel within the channel. Raising the carriage within the channel causes the cantilever to transition to the open position, and lowering of the carriage causes the cantilever to transition to the closed position.

A parasol includes a pole of a tension rod-type between a ceiling surface and a floor surface of a building, a lower hub penetrated by the pole and moves in the vertical direction along the pole, an upper hub fixed to a predetermined position of the pole, ribs joined to the upper hub, struts provided with respect to each rib and connecting the ribs and the lower hub, a handle operation unit for moving the lower hub along the pole, and a sheet between the ribs. The pole is divided into an outer pipe, a ceiling pipe attached to an upper side of the outer pipe, and a lower side pipe attached to a lower side of the outer pipe. The length of the pole in the vertical direction is adjustable while the position of the sheet is maintained at a height within a certain range from the floor surface.

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 an umbrella pole device, an electric umbrella and a telescopic device. The umbrella pole device includes an umbrella head, a middle rod, and an umbrella pole transmission assembly. The middle rod includes a plurality of casings, the casing in an innermost part of the middle rod is an inner casing, the casing in an outermost part of the middle rod is an outer casing, and one end of the inner casing is connected to the umbrella head. The umbrella pole transmission assembly is arranged in the inner casing, including a first transmission tube and a second transmission tube. The first transmission tube is telescopically sleeved with the second transmission tube. One end of the transmission tube is rotatably connected to the umbrella head, and one of the first transmission tube and the second transmission tube is a rectangular spring.

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.
