  • Patent number: 5655460
    Abstract: An apparatus for separating and supporting an article from a base surface includes at least one spacer having a first surface engageable with the base surface, a second surface spaced from the first surface and engageable with the article to be supported, and a third surface extending between the first and second surfaces. The third surface defines coupling members or portions for releasibly interlocking adjacent spacers with respect to one another. The second surface can be defined by at least one elongated member having opposite ends formed to allow interconnection between identical spacers. The interconnection between the spacers can be accomplished by one end of the elongated member including a coupling member and the opposite end having a mating receiving member. An integral pedestal portion can be of sufficient length to separate the second surface and the article to be supported from any undesirable substance that is located on the base surface.
