ABSTRACT:
An airtight spa cover (11) supported by air generated by the spa pump and the spa blower (29). The cover is attached to the external periphery of the spa walls (17) and includes a skirt (29) that extends into the spa water (35), adjacent to the internal periphery of the spa walls (17). The pressure of the air trapped between the skirt (24), the surface (33) of the water, and the overlaying portion of the cover (11) is adequate to support an adult. The attachment mechanism is designed to prevent unauthorized entry when the spa cover is pressurized. The spa cover (11) includes an air ventilation pipe (49) whose lower end, initially, lies beneath the surface (33) of the spa water (35). As the pressure rises, the lower end rises above the surface of this spa water allowing trapped air to escape. The cover rises and falls until a pressure balance is achieved. The spa cover is deflated by raising a pressure release pipe (59) to allow the air trapped in a dead air space (37) to escape.
