Abstract

A grid (250, 280) is disclosed which can be used as part of a salt platform (10, 50, 80) to support salt in an ion exchange water softener. The grid is preferably formed of ABS plastic and has a border portion (252) and bands (254, 256) without holes (274) formed therethrough for strength. When the grid is used as part of a salt platform having vertically oriented members (12-24) with open upper ends, cap portions (258-270), without holes formed therethrough, are used to cover the upper ends of the members.

Claims

1. A salt platform for supporting a load of salt in a brine tank, comprising:

a plurality of vertically oriented sheets, each of said sheets having a plurality of apertures formed therethrough, and defining an upper edge;

a plurality of first horizontal tubes, each of said first tubes being inserted through an aperture in each of said sheets, each of said first tubes having a first hole formed therethrough adjacent a first end thereof and a second hole formed therethrough adjacent a second end thereof;

a plurality of horizontal spacing tubes, each of said spacing tubes having a predetermined length corresponding to the desired separation between each of the vertically oriented sheets, the spacing tubes being concentric with and surrounding the first tubes between each of the sheets to space the sheets apart from each other; and

a first fastener placed in the first hole in each of said first tubes and a second fastener placed in the second hole in each of said first tubes to hold the platform together.

2. The salt platform of claim 1 further comprising a salt grid, at least one of said spacing tubes having an upper surface coplanar with the upper edges of the vertically oriented sheets to assist in supporting the salt grid thereon.

3. The salt platform of claim 1 wherein at least one of said first tubes has a third aperture at the first end thereof, a bolt being received in said third hole and having a head thickness selected so that an edge of the salt grid supported on the platform is supported by the first tube through said bolt head.

4. The salt platform of claim 2 wherein the grid is of acrylonitrile-butadiene-styrene (ABS) plastic.
