摘要： A free-standing shelf system comprises a plurality of shelves having passages through end portions thereof. A plurality of spindles support the shelves in spaced relation, the spindles having fastening elements extendible through the passages for axially interconnecting a pair of spindles with a shelf sandwiched therebetween. Interlocking tongue and groove portions on an opposed shelf surface and spindle end are provided. The tongue and groove portions are laterally adjacent the corresponding spindle fastening element and shelf passage for positively preventing lateral shifting of the shelf with respect to the spindles sandwiching same therebetween. The passage is circumferentially continuous opening through a shelf near the end thereof or alternatively is a circumferentially continuous opening formed at the juncture of two end abutting shelves by opposed, substantially hemicircular opening portions in the abutting shelf end edges. In the latter instance, the tongue and groove interlock prevents the abutting shelf ends from shifting apart laterally.
