Abstract

A spa cover lifting system is provided for selectively removing and replacing the cover of a spa. The spa cover lifter system has a frame configured to hold a cover of the spa and an actuator coupled to the frame. Selective actuation of the actuator by a user causes at least a portion of the frame and the cover to rotate about and between a first, closed position, in which access to the water of the spa is restricted, and a second, open position, in which access to the water of the spa is not restricted. The actuator and at least a portion of the frame are positioned below a deck that is around the outside of the spa so that the actuator and at least a portion of the frame are inaccessible to a user of the spa during normal usage.

Claims

1. A spa cover lifting system for selectively removing and replacing the cover of a spa positioned on a support surface, the system comprising:

a frame configured to hold the cover of the spa;

wherein the frame, in a closed position, defines a first plane parallel to and above a second plane defined by a deck around a base of the spa;

a support member fixedly, non-rotatably extends from a back carriage portion of the frame and, in the closed position, extends toward the support surface and has a preselected length that positions a distal end of the support member below the second plane;

an elongate attachment arm fixedly, non-rotatably extends from the support member at a right angle or at an obtuse angle relative to the support member;

wherein, in the closed position, the attachment arm extends in a direction away from the cover of the spa at a position below the second plane, wherein the attachment arm has a free end opposite the support member; and

an actuator coupled to the free end of the attachment arm and configured to selectively rotate the frame and the cover between the closed position, in which access to the water of the spa is restricted by the cover, and an open position, in which access to the water of the spa is not restricted by the cover.

2. The spa cover lifting system of claim 1, wherein the attachment arm is oriented at a right angle relative to the support member.

3. The spa cover lifting system of claim 1, wherein the attachment arm is oriented at an obtuse angle relative to the support member.

4. The spa cover lifting system of claim 1, wherein the system further comprises a deck positioned around at least a portion of a perimeter wall of the spa, wherein the deck is spaced from the support surface a predetermined distance and wherein the actuator is positioned below the deck.

5. The spa cover lifting system of claim 4, wherein at least a portion of the frame is positioned below the deck.

6. The spa cover lifting system of claim 4, wherein, in the open position, a portion of the frame is positioned substantially on the deck.

7. The spa cover lifting system of claim 1, wherein in the closed position, the cover is horizontal relative to the support surface and wherein in the open position, the cover is vertical relative to the support surface.

8. The spa cover lifting system of claim 7, wherein the deck is positioned around at least a portion of a perimeter wall of the spa, and wherein the deck is spaced from the support surface a predetermined distance.

9. The spa cover lifting system of claim 8, wherein the free end of the attachment arm is positioned below the deck.

10. The spa cover lifting system of claim 8, wherein the frame further comprises at least one mount configured to support at least a portion of the frame and the cover, wherein the mount has a proximal end, and an opposed distal end configured to be positioned on the support surface.

11. The spa cover lifting system of claim 10, wherein the attachment arm and the support member are rotatably coupled to the mount for rotation relative to the mount.

12. The spa cover lifting system of claim 10, wherein the proximal end of the mount is positioned below the level of the deck.

13. The spa cover lifting system of claim 10, wherein the proximal end of the mount is positioned adjacent to the level of the deck.

14. The spa cover lifting system of claim 8, wherein the actuator is positioned between the deck and the support surface.

15. The spa cover lifting system of claim 14, wherein the frame comprises a carriage sized and shaped to correspond to the size and shape of the cover, and wherein the carriage comprises a plurality of carriage portions coupled together that cooperate to define a carriage opening sized and shaped to hold the cover.

16. The spa cover lifting system of claim 15, wherein in the open position, the back carriage portion is positioned substantially on the deck.

17. A method of automatically, selectively covering a spa positioned on a support surface, the method comprising:

providing a spa cover lifting system comprising;

a frame configured to hold the cover of the spa;

wherein the frame, in a closed position, defines a first plane parallel to and above a second plane defined by a deck around a base of the spa;

a support member fixedly, non-rotatably extends from a back carriage portion of the frame and, in the closed position, extends towards the support surface and has a preselected length that positions a distal end of the support member below the second plane;

an elongate attachment arm fixedly, non-rotatably extends from the support member at a right angle or at an obtuse angle relative to the support member;

wherein, in the closed position, the attachment arm extends in a direction away from the cover of the spa at a position below the second plane, wherein the attachment arm has a free end opposite the support member; and

an actuator coupled to the free end of the attachment arm and configured to selectively rotate the frame and the cover between the closed position, in which access to the water of the spa is restricted by the cover, and an open position, in which access to the water of the spa is not restricted by the cover

and

actuating the actuator to rotate the cover to the first, closed position.

18. The method of claim 17, wherein in the closed position, the cover is substantially horizontal relative to the support surface and wherein in the open position, the cover is substantially vertical relative to the support surface.

19. The method of claim 17, wherein the deck is positioned around at least a portion of a perimeter wall of the spa, wherein the deck is spaced from the support surface a predetermined distance and wherein the actuator is positioned below the deck.

20. The method of claim 19, wherein at least a portion of the frame is positioned below the deck.
