The anchor disc device supports and anchors an umbrella and includes a tube post to receive the free end of the pole of a beach umbrella with an anchor disc portion attached to the free end of the tube post. An end cap is installed in the free end of an extension of the anchor disc portion. The anchor disc portion includes an outwardly extending flange for engagement with sand into which the device is buried to help avoid disengagement of the umbrella from the sand from wind and the like. For removal, the umbrella is rotated in large circular motions to form a cone-shaped hole after which the umbrella and connected anchor disc device can be removed. The anchor disc device can then be detached from the umbrella, if desired.

A novel umbrella is disclosed with a simplified structure that creates a clean, elegant profile with reduced component count and increased wind resistance. The umbrella includes a support post, a housing supported thereby, spokes pivotally disposed about the housing, a canopy, and an actuator. The housing has a top hub and a bottom hub. The actuator slides the hubs together to pivot the spokes away from the housing, whereby the umbrella moves from a closed position to an open position. Rollers are preferably retained within the top hub, and each spoke preferably has a spoke cam attached to one end. The spokes pivot away from the housing by having a roller surface of each spoke cam slide along each respective roller. The actuator may have a crank operated worm drive mechanism to raise and lower the canopy.

A beach umbrella anchoring and stabilizing device includes a support shaft having a proximal end, a distal end, and a hollow interior for receiving a beach umbrella. An anchoring container affixed to the support shaft includes an open top, a closed bottom, and a sidewall extending around the support shaft from the open top to the closed bottom. The sidewall defines a laterally extending reservoir for receiving sand to anchor the device underneath the beach surface and provide lateral support to a beach umbrella mounted into the support shaft. Stabilizing vanes protrude from the distal end of the support shaft and extend from the closed bottom to the distal end. Each of the stabilizing vanes defines a broad surface that engages sand when a rotational force is exerted onto the support shaft, thereby preventing rotation of the support shaft about a longitudinal axis thereof when buried under the sand.

A cantilevered umbrella, comprises a stand column, an umbrella tent and a cantilever. One end of the cantilever is connected with the stand column through a shell in a rotating mode, and other end is connected with the umbrella tent. Rotation of the cantilever drives the umbrella tent to rotate, with opening of the umbrella tent rotating to a certain angle in a relatively horizontal direction. The cantilevered umbrella further comprises a positioning part. One end of the positioning part is connected with the cantilever in a fixed mode, and other end extends into the shell. A first positioning portion is arranged on an inner wall of the shell, a second positioning portion is arranged on the positioning part, and the first and second positioning portions limit the cantilever in the circumferential rotating range through coordination.

A portable and stackable combination umbrella stand and table system comprised of a stand housing interoperable with a first lid portion to cover an opening in an umbrella securing body and a second lid portion to serve as a table top. The stand housing may be configured to form a concave area for receiving sand or other ballast to securely anchor the system in an upright position. As the concave area of the stand housing is filled with sand or other ballast, the first lid portion may serve as a cap by covering the upper portion of the umbrella securing body and prevents the ingress of sand or other ballast material from entering the channel (through which the umbrella pole may thereby be more easily inserted). The first lid may be removed to receive an umbrella within the umbrella securing body, and the second lid portion, which may be configured to be installed with the stand so as to form a table surface, may thereby facilitate snacking once ballast has been received. The housing is shaped so as to facilitate stacking of multiple systems. A variety of other features may be provided, including hooks and other retaining and storage features formed within or attached to the system, as well as a carrying handle and latches to secure the table top lid, any or all of which are designed for both personal and commercial use.

A parasol includes a tension rod-type pole that has multiple, length-adjustable telescopic portions; a lower hub that may be penetrated by the pole and that is configured to move in a vertical direction along the pole; a protruding portion that is provided on the pole and that is configured to restrict downward movement of the lower hub; an upper hub that is fixed to the pole; ribs that are joined to the upper hub and that are configured to rotate vertically but not horizontally; struts that are provided for the ribs and that connect the ribs and the lower hub; and a sheet that is provided between the ribs.

A device is disclosed for facilitating the anchoring and release of a structure to a medium, such as sand. The device is operable to inject a liquefying fluid into a medium upon a down stroke so as to facilitate liquefication within an area of the medium. The structure is simultaneously inserted into the area of the medium where liquefication has occurred by creating a vacuum within the structure, upon an upstroke, which facilitates the insertion operation. The distal end of the structure to be anchored is fitted with at least one protrusion for increasing the holding force of the medium. If desired, the distal end of the structure is also fitted with at least one fin operable under selective control of a user for reducing the holding force on the structure. In one embodiment, the user, when desiring to release the structure, rotates the structure, thereby rotating the fin. The fin, rotating within the liquefied medium, serves to reduce the holding force of the medium with respect to the structure, thereby allowing for easier removal of the structure by a user.
