Abstract
Spa side panels are trapezoidally-shaped and mounted in respective grooves defined by adjacent tapered corner pieces and their mounting brackets to accommodate differences in coefficients of expansion of the respective parts and prevent structural damage. Angled force transfer members are configured to mate with swept back side surfaces of a spa base pan to achieve a pedestal appearance, and the bottom surface of the base pan is constructed to reduce heat transfer to the spa support surface.
Claims6
The spa structure comprising:
- a base pan comprising a bottom surface having an outer perimeter;
- and
- a plurality of adjacent areas formed in said bottom surface, each area including a plurality of recessed fins, the plurality of areas of being arranged to reduce the surface area of the bottom surface which is in contact with a second surface upon which the bottom surface rests to thereby reduce heat transfer between the bottom surface and the second surface.
Dependencies are inferred from the claim text.
