Abstract:
1. A spa cover, comprising: a first and second rigid, fluid impermeable portion, and which each have a peripheral edge, and wherein the respective first and second portions are each hingedly joined to each other along a portion of each of their respective peripheral edges, and wherein the first and second portions are each assembled from a multiplicity of rigid, tongue and groove shaped, hollow, synthetic, and fluid impermeable boards which are affixed together, and which each have opposite first and second ends, and wherein the first and second ends define apertures which permit access to a hollow, narrowly elongated internal channel which extends between the opposite, first and second ends, and wherein the first and second rigid, fluid impermeable portions that are formed from the multiplicity rigid, tongue and groove shaped boards has a predetermined, upwardly facing surface area, and wherein the multiplicity of rigid tongue and groove shaped, and hollow synthetic boards, when formed into the first and second fluid impermeable portions, has a strength which can repeatedly support a weight of at least 112 pounds per square foot when this weight is downwardly applied to the upwardly facing surface area, without permanently deflecting and distorting the first and second rigid fluid impermeable portions; a multiplicity of individual, light-weight insulative inserts, and which are formed from a closed pore, fragile, insulative material which substantially resists the absorption of water, and wherein the respective insulative inserts are telescopingly received within the respective, narrowly elongated internal channels of each of the rigid, tongue and groove shaped fluid impermeable boards, and wherein the individual, light-weight insulative inserts substantially occlude the respective internal channels defined by the respective fluid impermeable boards; a peripheral edge cover which is removably mounted on, and extends along at least a portion of the peripheral edge of the respective first and second portions of the spa cover, and which sealably covers, and prevents immediate access to, and the movement of air into, or out of, the narrowly elongated, internal channels which individually extend between the opposite, first and second ends of each of the rigid tongue and groove shaped fluid impermeable boards, and wherein the peripheral edge cover is removable to permit the subsequent removal, and the replacement of the respective light-weight insulative inserts when the respective light-weight insulative inserts become ineffective; a hinge coupled to each of the respective first and second portions of the spa cover, and wherein the hinge facilitates the movement of the first portion relative to the second portion so as to facilitate an exposure of an underlying spa which is located below the spa cover, and wherein the spa has opposite sides; a generally U-shaped carrier having a centrally disposed cross-member which is located in a predetermined, spaced, closely adjacent relationship relative to the hinge, and within at least one of the elongated internal channels which are defined by the second portion of the spa cover, and is not located in physical contact with the hinge, and wherein the generally U-shaped carrier has opposite distal ends which are located outside of the elongated internal channel which is defined by the second portion of the spa cover, and which receives the centrally disposed cross-member, and wherein the respective distal ends of the U-shaped carrier are oriented in spaced relation relative to the opposite sides of the spa; and a pair of brackets which are mounted on the opposite sides of the spa, and which define a lift axis for the spa cover when the spa cover is moved from a position in covering relation relative to the spa, to a location where the underlying spa is exposed for subsequent use, and wherein the opposite, distal ends of the generally U-shaped carrier are individually, pivotally affixed to each of the respective brackets at the lift axis, and wherein the centrally disposed cross-member of the U-shaped carrier does not retard the movement of the first fluid impermeable portion relative to the second fluid impermeable portion as the underlying spa is being exposed.
