An accessory is provided that includes power supply module, a first functional module, and a second functional module. The power supply module can be configured to be suspended beneath an overhead support, such as a hub of an umbrella. The first functional module is configured to affix to the power supply module and to be powered by the power supply module to provide a user directed function. The second functional module is configured to be detachably coupled to either the power supply module or the first functional module to receive power from the power supply module directly or through the first functional module.

An umbrella tip structure for vertical placement of an umbrella is disclosed, including a fixed pillar, a movable barrel, a spring, and at least two tip blades. The umbrella tip structure is mountable to an umbrella in such a way that tip blades can be automatically expanded and/or collapsed so that in use, with a movable barrel positioned against a horizontal surface, the tip blades may be opened automatically to make the umbrella tip structure a stable and firm support stand that stably and firmly supports the umbrella in a vertical, upright condition on a horizontal surface, achieving vertical placement of the umbrella. The operation and use of the umbrella tip structure is simple and easy.

A coupling mechanism controls the location of the central primary draft load transmitting fixed-length link independently of the coupler. The coupling mechanism allows for translation in at least three orthogonal directions and for rotation of two distinct planes between coupled components, thereby providing a means for lateral shifting and articulation. The coupling mechanism mitigates unexpected rotation by restricting rotation along a longitudinal axis of the fixed-length link. Rotation of the coupling mechanism is furthermore controlled by means of a indexing turntable. The orientation and the position of the coupling mechanism is therefore determinant and predictable.

A type of positioning fixture with a connecting rod, consisting of a fixed clamping seat, a movable collet, a bolt and a connecting rod; the fixed clamping seat consists of a bolt seat, a fixed collet and a stroke plate; the bolt is engaged by threading it with the bolt seat; the end of the bolt is positioned with the movable collet. The connecting rod is movably riveted to the movable collet by a rivet and is provided with a dowel pin at the end; the stroke plate on the fixed clamping seat is provided with a wavy slot; the dowel pin on the connecting rod is inserted into the wavy slot to form the two-point positioning of the connecting rod.

A five-device-in-one solar-charging sun-visor foldable tiltable workstation comprises: an umbrella post, solar panels attached to the umbrella post, an electricity converter connected to the solar panels, a battery connected to the electricity converter for charging mobile devices, an electrical wire connected to the battery, a retractable extendable cable connected to the electrical wire, a spool rotationally connected to the retractable extendable cable, UBS connectors connected to the retractable extendable cable, an adjustable clamp attached to the umbrella post, having memory-stick and sunglass holders, a rotatable foldable tiltable table attached to the adjustable clamp, a foldable tiltable cup-holding system molded in the table for holding drinks in multiple angles, a waterproof transparent hooded pouch attached to the table for holding mobile devices in multiple angles while a user stands, sits, or swim in front of, or lays down under the pouch, and foldable tiltable sun-visors foldably hinged on the table for blocking the sun in multiple angles while a user stands, sits, or swim in front of, or lays down under the pouch.

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.

A solar charging umbrella uses solar power to charge electronic devices wirelessly, such as by a wireless or inductive charging port. The umbrella is self-sustained, capable of charging electronic devices in locations away from electrical outlets. The umbrella has a rechargeable battery that is recharged by sunlight. When charged, the umbrella's battery can charge devices when sunlight is not available. The umbrella supports simultaneous charging of higher power devices such as tablet computers.

The present invention relates to a method for controlling land surface temperature using stratospheric airships and a reflector. In the method for controlling land surface temperature using stratospheric airships and a reflector, four corners are connected to a lower end of support lines coupled to be disposed vertically downward from a plurality of airships, and sunlight is reflected by a reflector unfolded into a tetragonal shape in the air, wherein the reflecting surface of the reflector plate is maintained at an angle to remain perpendicular to an incident angle of sunlight to shield, or redirect, the land surface from incident sunlight.
