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 1):
A spa comprising:\n a housing defining an interior chamber for containing a volume of water, the chamber having an open upper end; a cover positionable over the housing for covering at least a portion of the open upper end; and a first lift assembly operable to selectively remove and replace the cover over the open upper end of the housing, the first lift assembly having:\n a lever arm having a first portion coupled to the spa cover, and a first end pivotably coupled to a sidewall of the housing at a pivot point 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 and is positioned outside the housing adjacent to the housing; and \n a resilient spring positioned inside the housing behind the sidewall, the spring having a first end drivingly coupled to the lever arm so that in the open position of the lever arm, the spring urges the lever arm to rotate toward the closed position, and in the closed position of the lever arm, the spring urges the lever arm to rotate toward the open.
