Convertible top for yacht
A retractable convertible top for a pleasure craft, including a canvas type fabric and stowable linkage mechanism, is described. This convertible top may be fully deployed and retracted automatically to provide a quick and efficient means of providing shelter for the open cabin of a pleasure craft while still allowing easy entrance and egress from the cabin when the top is fully deployed. The convertible top may be fully stowable within a small volume storage bin with watertight covers. The stowage bin may be integrated into the craft. The craft's existing hydraulic and control systems may be utilized to automatically deploy and retract the convertible top.
1. A retractable cover for a boat, the retractable cover comprising:
a linkage system;
a canopy coupled to the linkage system;
a hydraulically powered control system adapted to control multiple functions on the boat including at least one of a deployment and retraction of the canopy and at least one of a steering function and a propulsion function of the boat; and
a stowage bin, wherein the stowage bin is located to a rear of an open cabin of the boat, and wherein the canopy can be deployed to cover at least a portion of the open cabin while providing a passenger access and egress from the cabin.
2. The retractable cover of claim 1 , wherein a plurality of the multiple functions are powered by the hydraulically powered system.
3. The retractable cover of claim 1 , wherein the control system comprises a two button user interface or a three button user interface.
4. The retractable cover of claim 1 , wherein the linkage system comprises a plurality of support struts.
5. The retractable cover of claim 4 , wherein the plurality of support struts comprise at least one support leg, at least one extension arm, at least one top bow, and at least one header.
6. The retractable cover of claim 4 , wherein at least two of the plurality of support struts are coupled together by a pivotable joint.
7. The retractable cover of claim 5 , wherein the at least one header is collapsible.
8. The retractable cover of claim 7 , wherein the header is adapted to extend from and retract into the at least one extension arm.
9. The retractable cover of claim 5 , wherein the at least one header can be releasably coupled to a windshield frame of the boat.
10. The retractable cover of claim 1 , wherein the cover is adapted to be deployed while the boat is underway.
11. The retractable cover of claim 1 , wherein the control system is adapted to retract the deployed canopy into the stowage bin.
12. The retractable cover of claim 11 , wherein a retraction function of the deployed canopy can be paused at a predetermined position to allow for visual inspection and adjustment of the collapsing canopy.
13. The retractable cover of claim 12 , wherein the retraction function of the canopy can be paused in response to a signal from at least one sensor.
14. The retractable cover of claim 13 , wherein the at least one sensor comprises at least one optical sensor or at least one pressure sensor.
15. The retractable cover of claim 1 , wherein the ratio of deployed canopy length to stowed canopy length is at least 6:1, at least 8:1, or at least 10:1.
16. The retractable cover of claim 1 , wherein the canopy is adapted to extend over an area of at least 8 ft by 14 ft when deployed.
17. The retractable cover of claim 1 , wherein the linkage system comprises at least one pivot point coupling the linkage system to at least one anchoring point located within the stowage bin.
18. The retractable cover of claim 17 , wherein the at least one anchoring point and pivot point are adapted to support the combined weight of the linkage system and canopy when deployed.
19. The retractable cover of claim 18 , wherein the combined weight of the linkage system and canopy is at least 300 lbs or at least 400 lbs.
20. The retractable cover of claim 18 , wherein a center of gravity of the combined linkage system and canopy is approximately 7 ft forward of the at least one anchoring point when deployed.
