LIFT ASSEMBLY AND SPA INCLUDING THE SAME
First Claim
1. A lift assembly for a spa cover, the spa cover for covering an open upper end of a spa, the lift assembly comprising:
- a lever arm having a first portion for supporting a spa cover, and a first end for pivotable coupling to a sidewall of a spa for rotation of the lever arm about an axis between a closed position in which the spa cover rests on the upper end of the spa, and an open position in which the spa cover is displaced from the upper end of the spa, the first end extending substantially parallel to the axis;
a driving member coupled to the first end of the lever arm for rotation with the lever arm about the axis, the driving member extending substantially perpendicular to the axis; and
a resilient spring having a first end pivotally coupled to the driving member so that in the open position of the lever arm, the spring urges the lever arm to rotate toward the closed position.

Abstract
A lift assembly for a spa cover is disclosed. The spa cover is for covering an open upper end of a spa. The lift assembly includes a lever arm having a first portion for supporting a spa cover, and a first end for pivotable coupling to a sidewall of a spa for rotation of the lever arm between a closed position in which the spa cover rests on the upper end of the spa, and an open position in which the spa cover is displaced from the upper end of the spa. The lift assembly also includes a resilient spring having a first end coupled to the lever arm, and a second end for coupling to the sidewall of the spa. In the open position of the lever arm, the spring urges the lever arm to rotate toward the closed position. A spa including the lift assembly is also disclosed.

12. A method of moving a spa cover between an open position and a closed position, the method comprising:
-
applying force, by a rotator, to a lever arm, pivotably coupled to a spa and a spa cover in an open position, displaced from an upper end of the spa, to lift the spa cover toward a closed position, covering an upper end of the spa; and concurrently with said applying force by the rotator, applying force by a resilient spring to the lever arm to lift the spa cover toward the closed position, wherein the resilient spring is pivotably coupled to the spa and coupled to the lever arm.
