Abstract

A roller track comprises a series of rollers positioned with mutually parallal axes and transversely to the longitudinal direction of the series. The rollers are rotatably journalled in an elongated carrier which is received in a channel section of a housing which is closable at its open upper side by a cover plate. The carrier with the rollers is movable in vertical direction between a lower position, in which the rollers are completely sunk in the housing and an upper or operative position, in which the rollers extend by a fraction of their diameter through corresponding apertures in the cover plate. The carrier is assembled form a plurality of tilting members, each adapted for the rotatable support of a roller. The tilting members are coupled to each other at their upper sides at their lower sides. The coupling at the lower sides of the tilting members is formed by a connecting strip guided along the bottom of the channel section. The strip is movable in the longitudinal direction of the channel section between two end positions corresponding to the upper and lower position of the rollers, respectively.
