Abstract: A lift system for a spa cover includes a first lifter arm connected to a spa cover adjacent to a first end, and rotatably connected to a housing of a spa at a second end, a plate connected to the first lifter arm and rotatable with the first lifter arm, a linkage having a first end connected to the plate adjacent to a periphery of the plate, and a second end, and a linear actuator moveable between a retracted position and an extended position, a distal end of the linear actuator being connected to the second end of the linkage. Movement of the linear actuator from the retracted position to the extended position effects rotation of the plate and first lifter arm.

Abstract: A spa includes a shell having at least one cavity, the spa shell being configured to hold a volume of water, at seat insert having a plurality of hydrotherapy jets, the seat insert being received in the at least one cavity and defining a space between the seat insert and the shell, and a drain associated with the at least one cavity for removing water from the space between the seat insert and the shell.

Abstract: A cover for a spa includes a core, a water impervious coating in direct contact with the core, and a membrane encasing the core and water impervious coating.

Abstract: A method of manufacturing a cover for a spa includes the steps of vacuum molding a first shell member and a second shell member, bringing the first and second shell members into registration with one another to define a hollow cavity therebetween, and injecting a foam into the hollow cavity, wherein the foam is configured to bond with the shell members to create a unitary structural part that provides increased strength and rigidity.

Abstract: A lift system for a spa cover includes a first arm rotatable about a first pivotal connection with a side of a spa and pivotally connected to a spa cover, a lift mechanism configured to provide for rotation of the first arm about its pivotal connection to the side of the spa, and a mechanical linkage between the lift-assist device and the first arm.

Abstract: A lift system for a spa cover includes a first lift assembly configured for coupling to a first side of a spa, the first lift assembly including a motor and a first lever arm, the first lever arm having a first end configured for driving connection to the motor, and a second end configured for operative connection to a spa cover, and a clutch assembly configured to transmit torque from the motor to the first lever arm, the clutch assembly including a drive plate rotatably driven by the motor, a clutch plate arranged parallel to the drive plate, and a plurality of projections extending from one of the drive plate and the clutch plate and being configured to engage a corresponding plurality of recesses in the other of the drive plate and the clutch plate.

Abstract: A cover lift system for a spa includes a lifter handle having an upper arm and a lower arm telescopically connected to the upper arm, the upper arm being configured for operative connection to a cover of a spa, and the lower arm being configured for pivotal connection to a base of the spa, and an adjuster mechanism associated with the lifter handle for selectively adjusting a length of the lifter handle to allow for use of the lifter handle with spas of varying sizes.

Abstract: A lift system for a spa cover includes a fist lift assembly associated with a first side of a spa, and a second lift assembly associated with an opposed, second side of the spa. The first lift assembly includes a motor for applying an uncovering force to a spa cover. The second lift assembly includes a compression spring exerting a generally downward force on the cover when the cover is in the closed position, and a generally upwards force on the cover when the cover is moved towards an open position to assist in an uncovering operation. The second lift assembly also includes a tension spring configured to exert an upward force on the cover when the cover is in the open position to assist the first lift assembly in a covering operation.

Abstract: A through bulkhead connector for a spa includes a first fitting member and a second fitting member slidably connected to the first fitting member. The first fitting member includes a flange and an adapter portion extending from the flange and defining a passageway through the adapter portion and flange. The flange includes a receiving slot formed therein and which is open at one end for receiving a correspondingly shaped and dimensioned portion of the second fitting member.

Abstract: A method of manufacturing an article for a spa includes laminating a cosmetic film to a base substrate; laminating an acrylic film to the cosmetic film, the base substrate, cosmetic film and the acrylic film forming a layered assembly, and forming the layered assembly to shape.

Abstract: A cover for a spa includes a first cover member and a second cover member hingedly connected to one another about a seam. The cover further includes a sleeve associated with of one of the cover members at an approximate midpoint between an outer edge of the cover member and the seam. The sleeve is configured to receive a connecting rod of a lifting mechanism therethrough for transmitting an uncovering and/or covering force from the lifting mechanism to the cover.

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.
