Abstract

A cover assembly for a spa having a base and a shell supported by the base is provided. The cover assembly includes a cover member selectively movable between a covered position and an uncovered position, and a lifting assembly having a first lifting mechanism rotatably coupled to the cover member and to the base. The first lifting mechanism provides two axes of rotation for the cover member relative to the base.

Claims

1. A cover assembly for a spa having a base and a shell supported by the base, said cover assembly comprising:

a cover member selectively movable between a covered position and an uncovered position; and

a lifting assembly having a first lifting arm pivotally coupled at one end to said base and defining a first pivot point and at another end to said cover member and defining a second pivot point, a second lifting arm pivotally connected to said first lifting arm at said second pivot point, and a handle connected to a distal end of said second lifting arm;

wherein said second lifting arm is generally L-shaped such that a leg of said second lifting arm to which said handle is connected is generally parallel to said first lifting arm when said cover member is in said covered position atop said shell of said spa;

wherein said handle is positioned above said cover member when said cover member is said covered position atop said shell of said spa; and

wherein said first and second pivot points provide two axes of rotation for said cover member relative to said base.

2. The cover assembly of claim 1, wherein:

said two axes are vertically and horizontally offset from one another.

3. The cover assembly of claim 2, wherein:

said first lifting arm has a first depending guide plate and said second lifting arm has a second depending guide plate; and

wherein said cover member is rotatable about said first pivot point and said second pivot point between said covered position, in which said cover member rests atop said shell, and said uncovered position, in which said cover member is oriented generally vertically adjacent a sidewall of said base.

4. The cover assembly of claim 3, wherein:

said second guide plate includes a plurality of ridges that are received in a plurality of corresponding recessed tracks in said first guide plate.

5. The cover assembly of claim 4, wherein:

said ridges are arcuate in shape; and

said corresponding recessed tracks are arcuate in shape.

6. The cover assembly of claim 3, further comprising:

another lifting assembly positioned on an opposing side of said base from said lifting assembly, said handle extending between said lifting assembly and said another lifting assembly.

7. The cover assembly of claim 1, wherein:

said cover member has a substantially convex outer surface and includes a plurality of channels formed in said outer surface; and

wherein said handle is received in one of said plurality of channels when said cover member is in said covered position.

8. The cover assembly of claim 1, wherein:

said cover member is double-walled and is formed from rotational molded plastic.

9. A spa, comprising:

a base;

a shell supported by said base and configured to hold a volume of liquid;

a cover member selectively movable between a covered position atop said shell and an uncovered position adjacent to a sidewall of said base; and

a lifting mechanism having a first lifting arm pivotally coupled at one end to said base and defining a first pivot point and at another end to said cover member and defining a second pivot point, a second lifting arm pivotally connected to said first lifting arm at said second pivot point, and a handle connected to a distal end of said second lifting arm;

wherein said second lifting arm is generally L-shaped such that a leg of said second lifting arm to which said handle is connected is generally parallel to said first lifting arm when said cover member is in said covered position atop said shell of said spa;

wherein said handle is positioned above said cover member when said cover member is in said covered position atop said shell of said spa; and

wherein said first and second pivot points provide two axes of rotation for said cover member relative to said base for selectively moving said cover member between said covered position and said uncovered position.

10. The spa of claim 9, wherein:

said two axes are vertically and horizontally offset from one another.

11. The spa of claim 10, wherein:

said first lifting arm has a first depending guide plate and said second lifting arm has a second depending guide plate; and

wherein said cover member is rotatable about said first pivot point and said second pivot point between said covered position, in which said cover member rests atop said shell, and said uncovered position, in which said cover member is oriented generally vertically adjacent said sidewall of said base.

12. The spa of claim 11, wherein:

said second guide plate includes a plurality of ridges that are received in a plurality of corresponding recessed tracks in said first guide plate.

13. The spa of claim 12, wherein:

said ridges are arcuate in shape; and

said corresponding recessed tracks are arcuate in shape.

14. The spa of claim 9, wherein:

said cover member has a substantially convex outer surface and includes a plurality of channels formed in said outer surface; and

wherein said handle is received in one of said plurality of channels when said cover member is in said covered position.

15. A method of covering and uncovering a spa having a base and a shell supported by said base, said method comprising the steps of:

providing a cover member atop said shell; and

equipping said cover member with a lifting mechanism having a first lifting arm pivotally coupled at one end to said base and defining a first pivot point and at another end to said cover member and defining a second pivot point, a second lifting arm pivotally connected to said first lifting arm at said second pivot point, and a handle connected to a distal end of said second lifting arm;

wherein said second lifting arm is generally L-shaped such that a leg of said second lifting arm to which said handle is connected is generally parallel to said first lifting arm when said cover member is in a covered position atop said shell of said spa;

wherein said handle is positioned above said cover member when said cover member is in said covered position atop said shell of said spa; and

wherein said first and second pivot points provide two axes of rotation for said cover member relative to said base for selectively moving said cover member between said covered position atop said shell and an uncovered position adjacent to a sidewall of said base.

16. The method according to claim 15, wherein:

said first lifting arm has a first depending guide plate and said second lifting arm has a second depending guide plate; and

wherein said cover member is rotatable about said first pivot point and said second pivot point between said covered position and said uncovered position.

17. The spa of claim 16, wherein:

said second guide plate includes a plurality of ridges that are received in a plurality of corresponding recessed tracks in said first guide plate.
