ABSTRACT:
A hinge-type table top chain having a plurality of links which are disposed in series and hingedly connected together. Each link includes a metal link plate having wound hinge parts on opposite ends thereof, with the hinge parts of adjacent links interfitting and being joined together by hinge pins. The link plate has a central portion, preferably a substantially planar platelike portion, having engaging portions or openings associated therewith. A separate top plate of a plastics material is positioned to overlie the link plate. The top plate has projections which are integral therewith and project from the underside thereof, which projections cooperatively engage the central part of the link plate, such as by a snap-type connection, for fixedly but releasably connecting the plates together. The top plates are sized such that the edges of longitudinally adjacent top plates are positioned in opposed but closely adjacent relationship. In addition, either the link plate or the top plate may be provided with a pair of sidewardly spaced, transversely extending guide plates projecting downwardly therefrom for slidable guiding engagement with a fixed guide rail.
