An apparatus for providing shade to an individual is adjustable in three planes. In some embodiments, the shading apparatus include a primary shaft secured to a fixed base such as a pedestal seat. A height adjustable and telescoping secondary shaft is inserted concentrically into the primary shaft.
An apparatus for providing shade to an individual is adjustable in three planes. In some embodiments, the shading apparatus include a primary shaft secured to a fixed base such as a pedestal seat. A height adjustable and telescoping secondary shaft is inserted concentrically into the primary shaft. A pivot joint assembly is secured to the secondary shaft, and a shading device is mounted to the pivot joint assembly. The pivot joint assembly allows for rotational, pivoting, and sliding adjustment in order to provide positional flexibility to the individual seeking shade.

What is claimed is: 1. An apparatus for providing shade, comprising: a primary shaft having a first end and a second end, wherein the first end is secured to a fixed base; a secondary shaft mounted to the second end of the primary shaft and adapted for telescopic adjustment and rotational adjustmen
What is claimed is: 1. An apparatus for providing shade, comprising: a primary shaft having a first end and a second end, wherein the first end is secured to a fixed base; a secondary shaft mounted to the second end of the primary shaft and adapted for telescopic adjustment and rotational adjustment with respect to the primary shaft; a pivot joint assembly mounted to the secondary shaft and spaced apart from the primary shaft, wherein the pivot joint assembly is adapted for sliding adjustment, pivoting adjustment, and rotational adjustment with respect to the secondary shaft and comprises: a lower pivot joint secured to the secondary shaft, wherein the lower pivot joint is operable for locking at a first pivot angle; a boom shaft connected to the lower pivot joint; and an upper pivot joint secured to the boom shaft, such that the upper pivot joint is spaced apart from the lower pivot joint, wherein the upper pivot joint is operable for locking at a second pivot angle; and a shading device mounted to the pivot joint assembly. 2. The apparatus of claim 1, further comprising a mounting bracket and an anti-rotation device connected between the mounting bracket and the fixed base, and an anti-rotation collar adapted to secure the anti-rotation device to the fixed base. 3. The apparatus of claim 1, further comprising a mounting bracket between the first end of the primary shaft and the fixed base. 4. The apparatus of claim 1, wherein the secondary shaft is mounted concentrically with respect to the primary shaft. 5. The apparatus of claim 1, wherein the shading device comprises an umbrella with a support shaft, and wherein the support shaft is mounted to the pivot joint assembly. 6. The apparatus of claim 1, wherein the boom shaft is operable to provide the rotational adjustment and the sliding adjustment of the pivot joint assembly, and wherein the boom shaft is operable for locking in a desired position. 7. The apparatus of claim 6, wherein the first pivot angle has a range of zero degrees to 270 degrees with respect to a secondary shaft radial axis. 8. The apparatus of claim 6, wherein the second pivot angle has a range of zero degrees to 180 degrees with respect to a boom shaft longitudinal axis. 9. The apparatus of claim 6, wherein the boom shaft is adapted to rotate 360 degrees with respect to a boom shaft longitudinal axis. 10. The apparatus of claim 6, wherein the boom shaft is adapted for sliding adjustment along a boom shaft longitudinal axis. 11. The apparatus of claim 1, wherein the secondary shaft is adapted to rotate 360 degrees with respect to a secondary shaft longitudinal axis. 12. The apparatus of claim 1, wherein the shading device is removable from the pivot joint assembly. 13. The apparatus of claim 1, wherein the primary shaft is removable from the fixed base. 14. An apparatus for providing shade, comprising: a seat supported by a fixed base; a mounting bracket attached between the seat and the fixed base, the mounting bracket having a mounting sleeve extending from the mounting bracket; a primary shaft having a first end and a second end, wherein the first end is secured to the mounting sleeve; a secondary shaft attached to the primary shaft and adapted for telescopic adjustment and rotation adjustment with respect to the primary shaft; a pivot joint assembly attached to the secondary shaft, wherein the pivot joint assembly is adapted for sliding adjustment, pivoting adjustment, and rotational adjustment with respect to the secondary shaft and comprises: a lower pivot joint secured to the secondary shaft, wherein the lower pivot joint is operable for locking at a first pivot angle; a boom shaft connected to the lower pivot joint; and an upper pivot joint secured to the boom shaft, such that the upper pivot joint is spaced apart from the lower pivot joint, wherein the upper pivot joint is operable for locking at a second pivot angle; and a shading device attached to the pivot joint assembly. 15. The apparatus of claim 14, further comprising an anti-rotation device connected between the mounting bracket and the fixed base, and an anti-rotation collar adapted to secure the anti-rotation device to the fixed base. 16. The apparatus of claim 14, wherein the boom shaft is operable to provide the rotational adjustment and the sliding adjustment of the pivot joint assembly, and wherein the boom shaft is operable for locking in a desired position. 17. The apparatus of claim 16, wherein the first pivot angle has a range of zero degrees to 270 degrees with respect to a secondary shaft radial axis. 18. The apparatus of claim 16, wherein the second pivot angle has a range of zero degrees to 180 degrees with respect to a boom shaft longitudinal axis. 19. The apparatus of claim 16, wherein the boom shaft is adapted to rotate 360 degrees with respect to a boom shaft longitudinal axis. 20. The apparatus of claim 16, wherein the boom shaft is adapted for sliding adjustment along a boom shaft longitudinal axis. 21. The apparatus of claim 14, wherein the secondary shaft is adapted to rotate 360 degrees with respect to a secondary shaft longitudinal axis.
