Abstract

A salt platform (500) is disclosed which incorporates a top member (502), a bottom member (504) and a plurality of vertical spacing members (506). The top member 502 is preferably formed as an integral molding. The bottom member (504) is preferably identical to the top member (502). The top surface of the top member (502) forms a support for the salt grid. A salt grid (600) is also disclosed which has a series of lips (646) at the peripheral edge with each lip joining with the rest of the salt grid about a linear hinge line (648).

Claims

1. A salt platform, comprising:

a member forming a salt grid, the member having a center hub, a plurality of radially extending arms, a plurality of radial hubs and a circumferential element secured to said radial hubs, said center hub and radial hubs each for receiving a vertical support member and wherein each of said center hub and said radial hubs define a stepped cylindrical extension defining a cylindrical side surface and an annular end to receive the vertical support members.

2. The salt platform of claim 1 wherein the member is a top member, said salt platform further having a bottom member having a center hub, a plurality of radially extending arms, a plurality of radial hubs and a circumferential element secured to said radial hubs, said center hub and radial hubs each for receiving a vertical support member.

3. The salt platform of claim 2 further comprising a plurality of vertical support members secured between the center and radial hubs of said top member and said bottom member.

4. The salt platform of claim 1 wherein the center hub and radial hubs each define a cylindrical socket for receiving said vertical support members.

5. The salt platform of claim 1 wherein the member further has an inner circumferential element secured to said arms between said center hub and said radial hubs.

6. The salt platform of claim 1 wherein said center hub, said radially extending arms, said circumferential element and said plurality of radial hubs each define a top surface, the top surfaces lying in a single plane.

7. The salt platform of claim 1 wherein said center hub and said plurality of radial hubs define sockets, said arms having ends received in said sockets.

8. The salt platform of claim 1 wherein the member is integrally formed.

9. The salt platform of claim 1 wherein the member is formed of polyethelene.

10. The salt platform of claim 1 wherein the member is a molded member.

11. The salt platform of claim 1 wherein the member is a fabricated member.

32. The salt platform of claim 1 wherein the center and radial hubs form leg sockets, each leg socket having a plurality of ribs and a cruciform.

33. The salt platform of claim 32 wherein the ribs each have a rim tapered to permit easier insertion of a vertical support member.

12. An apparatus for use in a salt tank of a water softener, comprising:

a salt grid having a circumferential edge, a plurality of apertures therethrough and a plurality of lips formed at the circumferential edge thereof, each lip being joined with the remainder of the salt grid along a linear hinge line.

13. The apparatus of claim 12 further having a skirt mated with each of said lips to reinforce the hinge line.

14. The apparatus of claim 12 further comprising a plurality of leg sockets formed in the salt grid.

15. The apparatus of claim 14 wherein each leg socket has a plurality of ribs and a cruciform.

17. The apparatus of claim 12 further comprising a plurality of radial ribs extending from a center of the salt grid to proximate the circumferential edge of the salt grid.

18. The apparatus of claim 12 further having a plurality of circumferential ribs.

19. The apparatus of claim 12 wherein the salt grid is 24 inches in diameter.

20. The apparatus of claim 12 wherein the salt grid is 30 inches in diameter.

21. The apparatus of claim 12 wherein the salt grid is 39 inches in diameter.

22. The apparatus of claim 12 wherein the salt grid has a predetermined diameter.

23. The apparatus of claim 12 having at least one cutout.

24. The apparatus of claim 12 having at least two cutouts.

25. The apparatus of claim 24 wherein said at least two cutouts are of different size.

27. The apparatus of claim 12 further having three cutouts formed therein, a three inch, a four inch and a six inch cutout.

28. The apparatus of claim 12 formed of polyethelene.

29. The apparatus of claim 12 formed by polypropylene.

30. The apparatus of claim 12 wherein the salt grid is a unitary molding.

31. The apparatus of claim 12 wherein the salt grid is multiple pieces.

16. An apparatus for use in a salt tank of a water softener, comprising:

a salt grid having a plurality of apertures therethrough and a plurality of lips formed at the circumferential edge thereof, each lip being joined with the remainder of the salt grid along a linear hinge line, the salt grid having at least one cutout, said cutout having a plurality of circumferential holes at different radii to permit selecting the diameter of the cutout.

26. An apparatus for use in a salt tank of a water softener, comprising:

a salt grid having a plurality of apertures therethrough and a plurality of lips formed at the circumferential edge thereof, each lip being joined with the remainder of the salt grid along a linear hinge line, the apparatus having at least one cutout, said at least one cutout having a plurality of radially spaced apertures to permit selection of different sized passages in the said at least one cutout.

34. An apparatus for use in a salt tank of a water softener, comprising:

a unitary molded salt grid having a plurality of apertures therethrough and at least one cutout, said at least one cutout having a plurality of radially spaced apertures to permit selection of different sized passages in the said at least one cutout.
