Umbrella devices, assemblies, and systems are shown and described. In one embodiment an umbrella assembly includes an umbrella having an aperture along a distal portion of a canopy, and a flagstaff to removably mate within the umbrella.

A deployable frame for a weather and/or sun protection device, including: a mast with a longitudinal axis on which a slider is mounted so as to slide between a first position in which the frame is closed and a second position in which the frame is open; at least one rib connected by a stretcher to the runner, the rib including an end connected to a notch carried by one end of the mast, wherein the rib includes a first segment formed of a first part and a second part that are movable relative to each other about the extension axis of the first segment, the first part of the first segment of the rib is connected to the notch by a pivot connection about an axis which is perpendicular to a plane inclined obliquely to the longitudinal axis of the mast so that in the first closed position of the frame the first segment of the rib extends along the mast and in the second open position of the frame the first segment of the rib is moved away from the mast.

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.

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.

An umbrella is formed with a canopy having a light-up promotional display formed by one or more opaque/translucent/transparent letters formed in or added to the canopy, and a plurality of light emitting diodes (LEDs) positioned on the canopy beneath the one or more letters, and wiring to wire the plurality of LEDs together and to a source of electric power. The plurality of LEDs are distributed to light up each of the one or more letters when energized, and a switch is used to permit a flow of current from the source of electric power to energize the plurality of LEDs, when desired. The one or more letters are wired together to minimize a length of the wiring, and to minimize distortion and resistance of the canopy to being folded. The one or more letters may be formed of and/or may include a photo luminescent material, such as a phosphorescent material.

An umbrella includes: a pole part having a first end, a second end opposite the first end, and a pole axis extending through the first end and the second end; an umbrella part at the first end; and a ground engagement structure extending from the second end for engaging a ground. The ground engagement structure includes: a material shifting structure extending radially relative to the pole part; and a material receiving groove adjacent to the material shifting structure.
