Pool or spa cover sealing and support on water receptacle having waterfall chute

1. A pool or spa cover and a waterfall chute projecting from the top edge of a pool or spa water receptacle, comprising in combination:

a) the cover having sections hinge connected to allow one section to pivot downwardly toward the waterfall chute while the other section remains peripherally seated on the receptacle,

b) said one section having an edge portion or portions located to seat on receptacle edge portions at opposite sides of the chute, and which extend away from the chute and about the pool,

c) said one section locally configured to accommodate the cover to the chute as the cover pivots downwardly to seat on the pool or spa receptacle top edge.

2. The combination of claim 1 wherein the cover consists of synthetic foam to seal downwardly against the upper edge extent of the receptacle, and in proximity to the chute.

3. The combination of claim 2 wherein the chute projects from edge extent of the receptacle toward the open interior of the receptacle.

4. The combination of claim 1 wherein the cover is locally cut away at the underside of said one section, registering with the chute, whereby said one section has a peripheral portion that seats on the receptacle edge proximate the chute.

5. The combination of claim 4 wherein said local cut-away has a boundary that is convex toward a hinge connecting said sections, whereby the cut-away accommodates to the projecting extent of the chute.

6. The combination of claim 5 wherein a portion of the cover overlapping the cut-away may then seat or seal on the spa or pool side wall upper edge proximate the chute to provide a smooth, covering appearance of the seated cover.

7. The combination of claim 5 wherein the portion of the pool or spa side wall supporting the chute is elevated relative to the main extent of the pool or spa.

8. The combination of claim 1 including wedge shaped pads loosely suspended and interposed between section edges below a hinge connecting said sections, to seat against said edges as the one section pivots downwardly toward the chute, to relatively position the sections.

9. The combination of claim 1 wherein said one section also has local peripheral cut-outs to accommodate to receptacle upward projections spaced at opposite sides of, and from the chute.

10. In spa apparatus having a water receptacle with a side wall and a hinged cover with one section to be lowered to seat on said side wall, the combination comprising:

i) padding positioned between proximate ends of the cover sections to relatively position the sections in closed position,

ii) said padding configured to be self adjustable and provide cushioning as the sections are relatively closed together.

11. The combination of claim 10 wherein the padding is at opposite lateral ends of the sections, to self adjust and thereby align the cover over the receptacle wall during closing.

12. The combination of claim 10 wherein said one section is cut-away to vertically register with a waterfall chute carried by the sidewall.

13. The combination of claim 8 wherein each of said pads comprises a generally wedge shape resiliently compressible body and a thin flexible cover fitting over said body.

14. The combination of claim 13 including a flexible holder attached to said cover and configured to be supported by one of said sections to freely suspend the pad between said edges.

15. The combination of claim 10 wherein said padding comprises a generally wedge shaped resiliently compressible body and a thin flexible cover fitting over said body.

16. The combination of claim 15 including a flexible holder in the form of a strap attached to said cover and configured to be supported by one of said sections to freely suspend the pad between said edges.

17. For use in spa apparatus having a water receptacle with a side wall and a hinged cover with one section to be lowered to seat on said side wall, the combination comprising:

i) padding positioned between proximate ends of the cover sections to relatively position the sections in closed position,

ii) said padding configured to be self adjustable as the sections are relatively closed together,

iii) said padding comprising a wedge shaped resiliently compressible body and a thin flexible cover fitting over said body

iv) and support structure attached to said cover and configured to be supported by one of said sections to freely suspend the pad between said edges,

v) said padding tapering downwardly and having opposite sides compressed by and between said edges.

18. The combination of claim 13 wherein each pad tapers downwardly and has opposite sides compressed by and between said section edges, thereby to position the one section, aligning it horizontally relative to the chute as the cover is closed downwardly.

19. The combination of claim 18 wherein the hinge comprises flexible material overlying a gap formed between the sections, to block upward escape of heat from spa water, the pads located in said gap.
