Self-adjusting sun shade assembly
View Patent ↗The presently disclosed subject matter is directed to a sun shade assembly. Particularly, the assembly includes a sail that releasably attaches to a pair of ribs, providing shade to the user. At least one support arm can be used to reinforce the ribs. A mast provides height to the assembly and includes an anchor that allows the assembly to be secured into a support surface (e.g., sand). The ribs and support arms rotate about the mast, thereby self-adjusting the direction of sail in response to the wind blowing. The assembly further includes a tension adjuster that can be tightened or loosed to control the rotation of the ribs and support arms in response to wind conditions.
1. A sun shade assembly comprising:
a pair of ribs defined by a first end and a second end, wherein the first end of each rib is attached to a pivot cap;
a sail with a front edge comprising a channel sized and shaped to house each rib such that the ribs extend across the edge;
a mast comprising a first end and a second end, wherein the first end is operably connected to the pivot cap, wherein the pivot cap can freely rotate about the mast;
at least one support arm with a first end and a second end, wherein the first end of the support arm is attached to a rib and the second end of the support arm is attached to a slider configured to move up and down the mast; and
an anchor operably connected to the second end of the mast;
wherein the pivot cap, ribs, slider, and support arms are configured to rotate about the mast in response to blowing of the wind.
2. The assembly of claim 1 , wherein the pivot cap rotates about the mast at an angle of about 0-360 degrees.
3. The assembly of claim 1 , wherein the ribs are configured at an angle of greater than 180 degrees relative to each other.
4. The assembly of claim 1 , wherein one face of the pivot cap comprises a lock defined by a bridge comprising and opening and a slidable arm that moves to cover and expose the opening.
5. The assembly of claim 1 , wherein the slider is configured as a collar that fits around the exterior circumference of the mast.
6. The assembly of claim 1 , wherein the anchor is releasably attached to the second end of the mast.
7. The assembly of claim 1 , wherein the sail channel comprises one or more apertures to facilitate insertion of the ribs into the channel.
8. The assembly of claim 1 , wherein the sail channel comprises one or more apertures to allow direct contact between each rib and a corresponding support arm.
9. The assembly of claim 1 , wherein the sail has a top face and a bottom face, and wherein the bottom face includes at least one conduit configured as a channel with an open mouth positioned adjacent to the channel, a closed back end, and a length parallel with the length of the sail.
10. The assembly of claim 1 , wherein the sail has a top face and a bottom face and wherein at least one of the top or bottom faces comprises a coating.
11. The assembly of claim 1 , wherein the sail has an opposed rear edge comprising an adjacent hem constructed from a durable material.
12. The assembly of claim 1 , wherein the mast comprises at least one handle for gripping the mast.
13. The assembly of claim 1 , further comprising a tension adjuster that adjusts rotation of the pivot cap about the mast.
14. The assembly of claim 13 , wherein the tension adjuster is configured to permit the pivot cap, slider, ribs, and support arms to freely rotate about the mast, not rotate about the mast, or any level of rotation therebetween.
15. A method of using a sunshade, the method comprising:
positioning the anchor of a sun shade assembly in a support surface, wherein the sun shade assembly comprises:
a pair of ribs defined by a first end and a second end, wherein the first end of each rib is attached to a pivot cap;
a sail with a front edge comprising a channel sized and shaped to house each rib such that the ribs extend across the edge;
a mast comprising a first end and a second end, wherein the first end is operably connected to the pivot cap, wherein the pivot cap can freely rotate about the mast;
at least one support arm with a first end and a second end, wherein the first end of the support arm is attached to a rib and the second end of the support arm is attached to a slider configured to move up and down the mast; and
an anchor operably connected to the second end of the mast;
wherein the sun shade assembly self-adjusts in response to the blowing of the wind.
16. The method of claim 15 , wherein the sail has a top face and a bottom face, and wherein the bottom face includes at least one conduit configured as a channel with an open mouth positioned adjacent to the channel, a closed back end, and a length parallel with the length of the sail.
17. The method of claim 15 , wherein one face of the pivot cap comprises a lock defined by a bridge comprising and opening and a slidable arm that moves to cover and expose the opening.
18. The method of claim 15 , wherein the sail has an opposed rear edge comprising an adjacent hem constructed from a durable material.
19. The method of claim 15 , wherein the sunshade assembly further comprises a tension adjuster that adjusts rotation of the pivot cap about the mast, and
wherein the method further includes adjusting the tension adjuster to achieve a desired amount of rotation of the pivot cap, ribs, support arms, slider, and sail relative to the non-movable mast.
20. The method of claim 19 , wherein the tension adjuster can be adjusted to allow the pivot cap, slider, ribs, and support arms to freely rotate about the mast, not rotate about the mast, or any level of rotation therebetween.
