Oscillating canopy sunshade device with frame structure for climate and solar mitigation
A sunshade device and sunshade management system for mitigating the effects of climate change and direct and prolonged exposure to the sun, the sunshade device including a canopy attached to a collapsible web or frame structure. The frame structure can be collapsed or opened by operation of an electric motor. The sunshade device is positioned above the ground by electrically powered lifting devices that are powered by a battery system that is charged by solar cells. A sunshade management system controls the status of the sunshade device, and can collapse the frame and activate the lifting devices to position the sunshade in the sky, and open the frame and deactivate the lifting devices to allow the sunshade device to slowly descend while providing shade to areas below the sunshade device.
1. A sunshade device, comprising:
a canopy for providing shade from the sun formed of a flexible lightweight sheet material;
a collapsible frame structure, the canopy being affixed to the frame structure, wherein the frame structure has a downwardly extending central tubular shaft having an upper end, and a lower end and an exterior, with an annular slider positioned on the exterior of the tubular shaft, the frame structure having three or more arms pivotally mounted to and extending outwardly from the central tubular shaft, and a support connector pivotally mounted to and extending from the annular slider to each of the three or more arms; whereby downward movement of the annular slider on the tubular shaft from the tubular shaft upper end towards the tubular shaft lower end causes collapse of the frame structure; whereby upward movement of the annular slider on the tubular shaft from the tubular shaft lower end towards the tubular shaft upper end causes opening of the frame structure;
at least one electrically powered lifting device attached to the frame structure or canopy;
a rechargeable battery power system operatively connected to the at least one lifting device;
solar cells provided on the canopy, said solar cells being operatively connected to the battery power system to charge the battery power system;
a sunshade management system controlling the one or more lifting devices and the frame structure;
the sunshade management system controlling the frame structure to collapse the frame structure and activate the lifting devices to lift the sunshade device;
the sunshade management system controlling the frame structure to open the frame structure and deactivate or reduce activity of the lifting devices to allow descent of the sunshade device.
2. The sunshade device of claim 1 , wherein the frame structure is collapsed during lifting of the sunshade device, thereby reducing drag on the canopy during lifting of the sunshade device.
3. The sunshade device of claim 1 , wherein the frame structure is opened during descent of the sunshade device, the canopy thereby providing shade and increased air resistance during periods of descent.
4. The sunshade device of claim 1 , further comprising
an electrical motor operatively connected to the battery power system, with a linkage to the annular slider to provide downward movement of the annular slider on the tubular shaft and upward movement of the annular slider on the tubular shaft.
5. The sunshade device of claim 4 , wherein said electric motor is operable in two directions and said linkage comprises a line having two ends, the two ends being engaged to the annular slider, the line extending through the tubular shaft and around pulleys to the outside of the tubular shaft to form a loop, the line being engaged with a pulley provided on a drive shaft of the electrical motor.
6. The sunshade device of claim 5 , wherein said electric motor is operably connected to and controlled by the sunshade management system, whereby the sunshade management system operates the electric motor to move the annular slider downwardly on the tubular shaft to collapse the frame structure, and the sunshade management system operates the electric motor to move the annular slider upwardly on the tubular shaft to open the frame structure.
7. The sunshade device of claim 6 , wherein one or more battery storage units of the rechargeable battery power system are located below the tubular shaft.
8. The sunshade device of claim 6 , wherein the at least one lifting device comprises a propeller-driven device.
9. A sunshade device, comprising:
a canopy for providing shade from the sun formed of a flexible lightweight sheet material;
a collapsible frame structure, the frame structure having a downwardly extending central tubular shaft having an exterior having an upper end, and a lower end;
an annular slider positioned on the exterior of the tubular shaft,
the frame structure having three or more arms pivotally mounted to and extending outwardly the central tubular shaft, and a support connector pivotally mounted to and extending from the annular slider to each of the three or more arms, whereby downward movement of the annular slider on the tubular shaft from the tubular shaft upper end toward the tubular shaft lower end causes collapse of the frame structure, and whereby upward movement of the annular slider on the tubular shaft from the tubular shaft lower end toward the tubular shaft upper end causes opening of the frame structure;
the canopy being affixed to the frame structure;
an electrical motor with a linkage to the annular slider to provide downward movement of the annular slider on the tubular shaft and upward movement of the annular slider on the tubular shaft,
at least one electrically powered lifting device attached to the frame structure or canopy;
a rechargeable battery power system operatively connected to the at least one lifting device and the electric motor;
solar cells provided on the canopy, said solar cells being operatively connected to the battery power system to charge the battery power system;
a sunshade management system controlling the one or more lifting devices and the electric motor;
the sunshade management system controlling the electric motor to collapse the frame structure and activate the lifting devices to lift the sunshade device;
the sunshade management system controlling the electric motor to open the frame structure and deactivate or reduce activity of the lifting devices to allow descent of the sunshade device.
10. The sunshade device of claim 9 , wherein said electric motor is operable in two directions and said linkage comprises a line having two ends, the two ends being engaged to the annular slider, the line extending through the tubular shaft and around pulleys to the outside of the tubular shaft to form a loop, the line being engaged with a pulley provided on a drive shaft of the electrical motor.
11. The sunshade device of claim 10 , whereby the sunshade management system operates the electric motor to move the annular slider downwardly on the tubular shaft to collapse the frame structure, and the sunshade management system operates the electric motor to move the annular slider upwardly on the tubular shaft to open the frame structure.
12. The sunshade device of claim 11 , wherein the frame structure is collapsed during lifting of the sunshade device, thereby reducing drag on the canopy during lifting of the sunshade device.
13. The sunshade device of claim 11 , wherein the frame structure is opened during descent of the sunshade device, the canopy thereby providing shade and increased air resistance during periods of descent.
14. The sunshade device of claim 9 , wherein one or more battery storage units of the rechargeable battery power system are located below the tubular shaft.
15. The sunshade device of claim 9 , wherein the at least one lifting device comprises a propeller-driven device.
