A device for moving forward in an easy and efficient manner, articles such as canned goods, that are placed on a store shelf in order to facilitate their frontal display. The device makes use of positioning rods that are installed on the shelf so as to extend in parallel relationship with respect to the edge of the shelf. Two parallel side rails act as a support for the articles. These side rails extend on both sides of a central rail supporting a puller member and a backstop assembly. The side rails and the central rail are perpendicular to the edge of the shelf and are detachably fastened to the positioning rods, preferably by snapping. As a result, one may easily adjust their spacing as a function of the size of the articles. The backstop assembly is located at the back end of the puller member. It extends vertically and moves the articles closer to the front of the shelf when the puller member is pulled forward.

A chain according to claim 19, wherein said locking projection and said retaining recess both extend in a direction parallel to the axis of said roller. 21. A roller according to claim 1, wherein the tongue extends in a circumferential direction from said one circumferential end, said tongue having a pair of locking projections extending therefrom in opposite directions, both said opposite directions being transverse to said circumferential direction, and said recess extends circumferentially into said at least one circumferential end of the other of said two roller segments, and has a pair of opposed inner walls, a retaining recess extending into each of said inner walls, said retaining recesses also extending in directions transverse to said circumferential direction, and wherein said locking projections are sufficiently short in said opposite directions that the tongue, with said locking projections extending therefrom, can be pressed into the recess and the locking projections engaged with, and fitted into, the respective retaining recesses, during assembly, by movement of said one of the two roller segments in a direction in a radial plane relative to the other roller segment, said tongue being in engagement with said walls and said locking projections fitting into the respective retaining recesses. 22.
