Abstract
This invention is a support pad formed of a solidified mixture comprising crumb rubber and sufficient recycled polyethylene to bond the crumb rubber together. The composition has sufficient resiliency to dampen noise created by vibration of a condenser or other equipment positioned on the pad. The pad is lightweight and has sufficient strength to support the weight of an air conditioning condenser unit or similar equipment.
Claims16
A support pad for resting on a receiving surface and supporting an air conditioner compressor unit, comprising:
- a molded body made from crumb rubber and scrap plastic which has a perimeter wall adapted to be placed on the receiving surface and an upper planar member attached to the perimeter wall for receiving the air conditioner compressor unit, the perimeter wall having corners;
- said body having a plurality of vertical support ribs that extend from the underside of the upper planar member to even with the bottom of the perimeter wall;
- each of said vertical support ribs being spaced from and unattached to the perimeter wall for preventing warpage of the body during curing;
- and
- a pair of molded reinforcing ribs depending from the underside of the upper planar member and attached to the perimeter wall at each corner so as to form a triangular shape with the perimeter wall at the corner, said pair of molded reinforcing ribs extending from the underside of the upper planar member to even with the perimeter wall.
A pad for supporting an air contitioning condenser unit, the pad being made primarily from recycled materials, comprising:
- a box-shaped body having an upper planar member and depending sidewalls, the body having an open bottom side and being substantially hollow except for a plurality of vertical support members depending from the underside of the upper planar member and extending even with the bottom of the sidewalls for providing vertical support for the air conditioning condenser unit;
- the body having a composition comprising at least about 20 weight percent crumb rubber and at least about 50 weight percent scrap polyethylene so that the crumb rubber and the scrap polyethylene comprise at least about 90 weight percent of the body;
- the crumb rubber being formed by grinding or buffing used tires and having a rubber particle size ranging from about 200 mesh to about 10 mesh;
- the crumb rubber being dispersed throughout the polyethylene, the polyethylene and the crumb rubber being injection or compression molded to form the body as an integral unit;
- the polyethylene being the bonding agent that holds the body together;
- the body having a density ranging from about 0.02 pounds per cubic inch to about 0.04 pounds per cubic inch;
- and
- the composition including CaCO.sub.3 or flyash.
