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.

Claim (Index 7):
A method of operating a cover for a spa, the method comprising the steps of:\n positioning a cover atop a base of the spa; and equipping the spa with a lift assembly, including:\n pivotally connecting a first end of a lever arm to the base; \n pivotally connecting a second end of the lever arm to the cover; \n positioning a resilient spring interior to the base; \n operatively connecting a first end of the resilient spring to the lever arm; and \n connecting a second end of the resilient spring to the base; \n wherein the lever arm is configured for rotation to effect movement of the cover between a closed position in which the cover rests on the base, and an open position in which the cover is positioned adjacent to a sidewall of the base; and \n wherein the resilient spring is positioned so that in the open position of the cover, the resilient spring urges the lever arm to rotate toward the closed position of the cover, and in the closed position of the lever arm, the resilient spring urges the lever arm to rotate toward the open position of the cover.
