Abstract:
1. A row-pulley-system-assisted, solar-powered, simultaneously-and-oppositely-movable-top-and-bottom-weighted-bracket umbrella comprising: an outer tube; a pulley bracket, said outer tube having an outer-tube upper end, said pulley bracket attached to the outer-tube upper end of said outer tube; an inner tube, said pulley bracket having a central hole along its longitudinal axis, said inner tube inserted through the central hole of said pulley bracket into said outer tube such that said pulley bracket centers said inner tube therein; a spindle nut, said inner tube having an inner-tube lower end, said spindle nut attached to the inner-tube lower end of said inner tube; a weighted rib bracket, said weighted rib bracket predeterminedly weighted to integrate a predetermined gravitational force thereto, said inner tube having an inner-tube upper end, said weighted rib bracket attached to the inner-tube upper end of said inner tube; a weighted strut bracket, said weighted strut bracket predeterminedly weighted to integrate a predetermined gravitational force thereto, said weighted strut bracket slid over said outer tube such that said weighted strut bracket is able to move up and down on said outer tube; a plurality of canopy ribs each having a rib end, the rib ends of said canopy ribs pivotally attached to said weighted rib bracket; a plurality of canopy struts each having first and second strut ends, the first strut ends of said canopy struts pivotally attached to said weighted strut bracket, the second strut ends of said canopy struts pivotally attached to said canopy ribs at predetermined locations thereon, respectively; a transparent housing top for letting sun light to pass therethrough; a housing bottom attached to said transparent housing top; a solar panel for collecting energy from sun light; a circuit-board control center attached to said solar panel; a remote-control-device-signal receiver attached to said circuit-board control center, said transparent housing top and said housing bottom for protecting said solar panel, said circuit-board control center, and said remote-control-device-signal receiver; a battery attached to said circuit-board control center, said battery for storing the electricity from solar panel; a plurality of lights attached to said circuit-board control center for illuminating the ground area under the umbrella, said circuit-board control center attached to said housing bottom; an electric motor attached to said circuit-board control center, said circuit-board control center for converting the solar energy absorbed by said solar panel into electricity and for regulating the operation and energy management of said electric motor; an electric port attached to said electric motor; a plurality of control buttons operatingly attached to said circuit-board control center to operate said lights and said electric motor; a motor-and-spindle coupling; a threaded spindle, said spindle nut having a central threaded hole along its longitudinal axis, said threaded spindle having a thread mated to the thread of the central hole of said spindle nut, said motor-and-spindle coupling having a coupling upper surface and a coupling under surface, said electric motor attached to the coupling under surface of said motor-and-spindle coupling, said threaded spindle attached to the coupling upper surface of said motor-and-spindle coupling, said threaded spindle screwed upward through the central threaded hole of said spindle nut; a row-pulley system comprising a plurality of pulleys attached to said pulley bracket at predetermined locations thereon; a plurality of cables for raising and lowering said weighted strut bracket; and a cable tunnel, wherein, said electric motor rotating when powered to rotate said spindle such that said rib and strut brackets are raised and lowered simultaneously in two opposite directions to fold or unfold said canopy ribs and struts to fold or unfold the umbrella, respectively.
