An umbrella pole adapter to convert boat dining table leg mounts into temporary umbrella stands is presented. The umbrella adapter is a tubular oval design shape member consisting of an upper end and a bottom end with a center opening running thru the length. The unique tubular oval design shape and the rubber material for the center opening, enables the umbrella anchor pole to be inserted and secured inside the adaptor without the need for any other parts. The same unique tubular oval design shape and rubber material for the exterior wall, enables the adapter to be inserted and secured inside the boat hollow dining table leg mount, without the need for any other parts.

A five-device-in-one water-and-leaf-separating leaf-filtering water-collecting wind-blocking wind-redirecting marine-yacht-land-yacht-balcony-bumper-and-trailer-hitch-mountable sail comprises: a central-sail intersector; central-sail-supporting ribs; central-sail-rib-raising arms; an adjustable water-and-leaf-separating leaf-filtering central sail attached to the central-sail-supporting ribs for functioning as a water diverting device to predeterminately redirect the flow of water, functioning as a leaf filtering device to filter leaves from rain water when used upside down, functioning as a water collector to collect rain water when used upside down, functioning as a wind blocker to block wind, functioning as a privacy screen to provide privacy, functioning as an awning to angledly block rain and sun beams, functioning as a canopy to vertically block rain and sun beams, functioning as a wind redirector to redirect wind in and out of sail, and functioning as a sail-steering wind-powered device to steer the sail in multiple different directions; a ring-sail-rib intersector; primary automatically-centered-and-reinforced ribs for resisting bending and warping due to heavy winds, providing reinforced infrastructure for a sail when used on a wind-powered land vehicle, providing reinforced infrastructure for an emergency rainwater collecting device on a marine vessel, and providing reinforced infrastructure for a shade canopy; secondary automatically-centered-and-reinforced ribs for resisting bending and warping due to heavy winds, providing reinforced infrastructure for a sail when used on a wind-powered land vehicle, providing reinforced infrastructure for an emergency rainwater collecting device on a marine vessel, and providing reinforced infrastructure for a shade canopy; multi-rib-connecting automatically-centered-and-reinforced adjustable cores inserted into and screwed to the primary automatically-centered-and-reinforced ribs and the secondary automatically-centered-and-reinforced ribs, the multi-rib-connecting automatically-centered-and-reinforced adjustable cores for allowing manufacturers to shorten long ribs into the primary automatically-centered-and-reinforced ribs and the secondary automatically-centered-and-reinforced ribs to reduce the length and volume of the shipping package of the five-device-in-one water-and-leaf-separating leaf-filtering water-collecting wind-blocking wind-redirecting marine-yacht-land-yacht-balcony-bumper-and-trailer-hitch-mountable sail in a shipping container to save money from expensive shipping costs, and securely and reinforcingly connecting the primary automatically-centered-and-reinforced ribs to the secondary autom

An article for providing shade includes a sunshade and a slip-on mounting base. The sunshade includes a shield, a set of ribs connected to the shield, and a plurality of support arms connected to the shield. The slip-on mounting base includes a body that defines a cavity and an opening. The body is configured to slip on the back portion of an item of outdoor furniture into the cavity through the opening. The body is stretchable and is configured to stretch to receive the back portion of different items of outdoor furniture with different sizes. The slip-on mounting base includes a plurality of receptacles attached to the body. Each receptacle includes an opening to receive a support arm of the sunshade. Each receptacle holds the corresponding support arm such that the shield, when unfolded, covers at least a portion of the back portion of the item of outdoor furniture.
