## Abstract

A molded plastic system for use in constructing footings or supports for structures, preferably for supporting a deck. The system includes a base that includes a lower peripheral flange that extends in a substantially horizontal plane in use with the peripheral flange having an upper facing surface and a lower facing surface and an upright post that is integral with the base, extends upwardly from the upper facing surface of the base and is hollow to define a top opening of the base. The system also includes a column that includes top and bottom ends. The bottom end of the column is positioned in the base opening and extends in a generally vertical direction from the base. A cap includes a bottom end having an opening into which the top end of the column is placed for mounting the cap from the column. The cap further includes opposed side tangs that define therebetween an open channel for receiving a support structure.

## Claims

### Claim 1

A molded plastic system for use in constructing footings or supports for structures, preferably for supporting a deck, said system comprising:
a base that includes a lower peripheral flange that extends in a substantially horizontal plane in use;
the peripheral flange having an upper facing surface and a lower facing surface;
the base further including an upright cylindrical post that is integral with the peripheral flange, extends upwardly from the upper facing surface of the peripheral flange and is hollow to define a top cylindrical opening of the upright cylindrical post;
a column that includes top and bottom ends;
the bottom end of the column being positioned in the opening of the post of the base and the column extending in a generally vertical direction from the base; and
a cap that includes a bottom end having an opening into which the top end of the column is placed for mounting the cap around an outer surface of the top end of the column;
the cap further including opposed side tangs that define therebetween an open channel for receiving a support structure;
said lower peripheral flange of the base being circular and having a thickness that is substantially less than a diameter of the peripheral flange;
said column is in the form of a plastic tube or pipe and being cylindrical;
an outer diameter of the column being less than an inner diameter of the cylindrical opening of the post of the base so that the bottom end of the column fits in the opening of the post of the base;
the lower facing surface of the peripheral flange having ridges that assist in the securing of the base in a ground material;
the ridges extending downwardly from the lower facing surface of the peripheral flange;
the ridges being spaced ridges that are disposed in respective orthogonal ridge sets so as to form a right angle grid pattern that includes multiple sets in orthogonal directions;
the width of each ridge being less than the spacing between the ridges;
said base further including a plurality of support ribs that each extend between the upper facing surface of the flange and an outer surface of the post of the base;
each of the support ribs being of substantially triangular shape and each of the support ribs have respective sides that are integrally formed with the upper facing surface of the flange and an outer surface of the post of the base;
the plurality of support ribs being spacedly disposed about the post of the base to provide a reinforcement for the post of the base;
said cap also being cylindrical and the tangs each including a flat inner surface that defines the open channel of the cap, that has a width less than an outer diameter of the cap, that has a channel depth measured along a vertical longitudinal axis of the cap and that has a curved outer surface that is contiguous with the cylindrical outer surface of the cap;
both said tangs having an aperture extending therethrough for receiving a fastening means for securing the support structure in the channel between the tangs;
each said aperture in the tang extending therethrough in a direction that is orthogonal to the vertical longitudinal axis of the channel of the cap so that the fastening means extend in the same direction into the support structure on opposite sides thereof.

### Claim 2 (depends on 1)

The molded plastic system of claim 1 wherein the apertures in the tangs are in a substantially straight alignment with each other.

### Claim 3 (depends on 1)

The molded plastic system of claim 1 wherein each support rib extends along the outer surface of the post of the base a distance less than half the height of the post of the base.

### Claim 4 (depends on 1)

The molded plastic system of claim 1 wherein each aperture has an indented stepped section of a diameter greater than the diameter of the aperture.
