  • Patent number: 5440841
    Abstract: A floor pedestal module for being assembled together with a multiplicity of other like modules to form a raised floor providing space beneath the module for electrical and/or communications wiring. The module includes a base having an upper surface and opposed lower surface and four integrally-formed supporting legs formed of a high density, heavy duty plastic material. The lower surface of the module defines a pilot hole integrally-formed in the base for accepting a drill bit. At least two spaced-apart reenforcing ribs are formed in the base concentric with the pilot hole and define therebetween a circular area for being cut out to form an enlarged access hole. The utility receptacle module includes an enlarged flange for being supported by the upper surface of the pedestal module surrounding the access hole. A utility access port is provided in the module for receiving and supporting the electrical or communications utility receptacle.
