  • Patent number: 5570795
    Abstract: A display stand includes multiple support surfaces which can be configured to lie in a single plane to form a table top or in vertically spaced planes to form a multi-tiered display stand. The display stand includes a center section and one or more extensions which substantially surround the center section. The center section is supported by legs which are pivotally attached to the center section. The extensions include locking members disposed along an inner edge thereof for releasably engaging the outer edge of the center section or an adjacent inner extension. When the center section and extensions are locked together, they lie in a common plane to form a table top. When the extensions are disengaged from the center section and each other, the extensions can be lowered so as to rest on the legs in a vertically spaced relationship to one another. The height of the display stand can be adjusted by pivoting the legs inwardly and outwardly relative to the vertical axis of the display stand.
