Table top

A conventional table comprising a stationary table top having a generally planar upper surface bounded by a peripheral edge and a skirt depending downwardly from said peripheral edge, a support maintaining said table top in an elevated position, a flexible substrate extending across said table top and having an undersurface in engagement with and supported by said planar upper surface and an oppositely directed surface having information disposed thereon, said substrate extending adjacent the peripheral edge of said top so as to cover substantially said planar upper surface, a rigid transparent cover extending across said table top above the oppositely directed surface of said flexible substrate to provide protection therefor, a retaining ring extending about said peripheral edge and securing said cover to said table top, said retaining ring comprising a first member extending inwardly from the peripheral edge of the table to contact said cover and a second member depending downwardly from said first member and overlapping and conforming to the contour of said skirt and releasable retainers passing through said second member to secure said ring to said table top and to facilitate removal of said cover and replacement of said substrate on a periodic basis, wherein said retainers prevent movement of said retaining ring relative to said planar upper surface.
