ABSTRACT:
To provide support for a plurality of shelf elements disposed one above another, each shelf element is provided with one or more apertures for receiving tubular shelf supporting posts and each aperture is arranged to be closed by means including a support sleeve projecting from a lower surface of each shelf element together with support means mounted on the inner surface of said support sleeve for supporting and positioning suitable closure means disposed within each shelf aperture and mounted on said support means so as to provide a partial closure therefor but which is adapted to receive the lower end of a support post for another higher shelf. Each shelf element affords a multiplicity of arrangements for receiving mounting posts so that the unused shelf apertures are partially closed so as not to derrogate from the function of the shelf as a supporting device for various items to be supported or displayed.
