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.
Claims4
In a spa structure, a force transfer member comprising:
- a first half and a second half, the first half and second half being configured to slidably mate together such that the length of the force transfer member can be selectively adjusted;
- wherein the first half has a rectangular receptacle formed at an upper end thereof and the second half has a foot of rectangular cross-section extending from a lower end thereof;
- and
- wherein the force transfer member includes an upper stepped edge which forms into an angled surface, which angled surface continues into a second step, the rectangular receptacle being located above said first step and the foot being located below the angled surface.
The apparatus of claim 2 wherein the first and second halves are held in position with respect to one another by first and second tabs formed on the first half and first and second tabs formed on the second half.
The force apparatus of claim 3 wherein the interior of the first half has height markers located adjacent respective slots to indicate a particular length which can be achieved by utilizing a selected slot, and wherein during assembly, the first and second tabs on the second half slide into one of a plurality of groove pairs formed on the respective outer surfaces of the first half to select a particular height, while the first and second tabs on the first half enter into respective slots of the second half.
The apparatus of claim 4 wherein when the first and second tabs of the second half reach the end of the respective grooves of the first half, they snap down over a side surface of the first half to hold the first and second halves together, while the first and second tabs of the second half enter a pair of the slots to further hold the assembly together.
