Television base casting

Abstract

The PTV cabinetry of the present invention utilizes an integrally weighted base that enables the cabinet to satisfy load bearing and tip over standards without requiring the addition of separate weights. The base preferably includes a raised region and at least one lower region. Fill material is poured into the base, and substantially within the lower region, and allowed to set and harden. The fill material used is any suitable material having a density sufficient to act as a weight, such as, e.g., a concrete and fiber mixture or a metallic material. The raised region of the base may include a plurality of openings that allows heat to dissipate from within the interior space of the cabinet. The integrally weighted base of the present invention replaces a typical flat bottom panel of a typical PTV cabinet and further eliminates the need for attaching separate weights onto a bottom panel of a typical PTV cabinet.
