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.

Some umbrellas include a support assembly, canopy assembly, and a toroidal air bladder. The support assembly includes a pump and a handle. The canopy assembly includes a plurality of support ribs attached to the handle, and a sheet attached to each of the support ribs. The toroidal air bladder is coupled to the air pump, and the air bladder disposed about the handle and engages the support ribs.

A straight-pole sun umbrella hand-cranking structure comprises a standing pole and a shell fixed on the standing pole, wherein the shell comprises a first outer shell and a second outer shell. The shell is integrally fixed with one side of the standing pole, and a gear is arranged within the first and the second outer shells. A cranking shaft passes through the gear and is connected to an anti-slip mechanism, and a cranking handle is externally connected to the cranking shaft. The anti-slip mechanism comprises a torsion spring, wherein the torsion spring is sleeved on the end portion of the cranking shaft. The torsion spring is arranged at the tail end of the cranking shaft such that the anti-slipping performance is improved by the elastic force of the spring. As the aforesaid structure is protected against abrasion, its functional life is significantly prolonged.

A protective device configured to provide a user with body protection includes an umbrella having a canopy and a centrally positioned shaft extending from a center of the canopy. The shaft includes a telescopic stem configured to support the protective device when configured in its extended position. A plurality of umbrella spines extends from the centrally positioned shaft in a radial direction from the center of the canopy. Each umbrella spine has a proximate end originating adjacent the centrally positioned shaft and a distal end spaced apart from and opposite the proximate end. The distal end houses a telescoping rigid segment that is configured for radial extension from the distal end. The protective device further includes a protective member extending from a peripheral edge of the canopy. According to an aspect, the rigid segment is configured to support the protective member in the radially extended position.

An assembly for an umbrella, wherein the umbrella comprises (i) a first pole and a canopy coupleable to the first pole and (ii) a second pole to which the assembly is coupleable, wherein the assembly includes a collar securable about the second pole; an arm coupled to the collar, wherein the arm is rotatable relative to the collar between at least a closed position and an open position; at least one tab depending from the arm; at least a first opening associated with the collar; wherein in the closed position the at least one tab is positioned in the at least first opening and wherein in the open position the at least one tab is not positioned in the at least first opening. The invention is also directed to an umbrella including the aforementioned assembly.
