  • Patent number: 6212702
    Abstract: A lightweight, easy to assemble spa cover kit is disclosed herein. The cover kit includes a square or rectangular-shaped overhead cap pivotally attached at two corners along one end to two dual hinged support posts. The cap is made of lightweight, weather-proof material, such as molded fiberglass, and may include skylights to allow natural light through during use. The lower end of each dual hinged support post is pivotally attached to the deck surface on which the spa sits. During use, the upper end of each dual hinged support post is pivotally attached to one comer of the cap. After the lower ends of the dual hinged support posts are attached to the deck and the upper ends of the support posts are attached to the corners of the cap, the dual hinged support posts are slowly lifted to a vertical position while the cap is slowly rotated so that it is aligned horizontally over the spa.
