Abstract:
1. A device comprising: a shaft; an umbrella shade, coupled between a fastener and the shaft; a frame structure comprising: a cap, coupled between the fastener and the umbrella shade, comprising a cap opening and at least a first hinge portion and a second hinge portion, wherein the fastener couples to a bolt of the shaft that passes through the cap opening; a rigid first strut, comprising first and second ends, a third hinge portion at the first end, and between the first and second ends is a first sleeve that houses at least a first solar panel, wherein the first sleeve comprises a first clear surface that is above the first solar panel such that light can pass through the first clear surface to be collected by the first solar panel for conversion into electrical energy, and the third hinge portion is adapted to mate with the first hinge portion of the cap to form a first strut hinge; and a rigid second strut, comprising third and fourth ends, a fourth hinge portion at third end, and between the third and fourth ends is a second sleeve that holds at least a second solar panel, wherein the second sleeve comprises a second clear surface that is above the second solar panel such that light can pass through the second clear surface to be collected by the second solar panel for conversion into electrical energy, and the fourth hinge portion is adapted to mate with the second hinge portion of the cap to form a second strut hinge, the umbrella comprises an open position during which the umbrella shade is extended into a position away from the shaft and a closed position during which the umbrella shade is folded into a position closer to the shaft, when changing the umbrella from the closed to the open position, the umbrella shade pushes against a bottom of the struts while the umbrella shade is extended, causing the struts to rotate via the first and second strut hinges in a first turn direction, so that an angle between a top of the first strut and a top of the cap increases from a first angle in the closed position to a second angle in the open position, and the second angle is greater than the first angle, and when changing the umbrella from the open to the closed position, the bottom of the struts rest against the umbrella shade while the umbrella is folded, causing the struts to rotate via the first and second strut hinges in a second turn direction, so that the angle between the top of the first strut and the top of the cap decreases from the second angle to the first angle, and the second turn direction is opposite of the first turn direction; a rechargeable battery configured to be recharged by the first and second solar panels; and a charging terminal, coupled to the rechargeable battery, configured to connect to a portable electronic device and supply charge from the rechargeable battery to the portable electronic device.
