Abstract

An adjustable display rack is used in a shelf management system. The rack stores and displays products of a variety of shapes and sizes and automatically delivers the products to the front of the rack. The adjustable display rack includes a frame and a product supporting and feeding assembly. The assembly includes product tracks that can be added or removed as needed and that can be separated by varying distances depending on the width desired. The assembly also includes dividers. The product tracks and dividers can be separate or integral. The product tracks have raised rails extending from a front of the track to a back of the rack for attachment of a removable pusher block and a roll spring which urges the pusher block forward. Additionally, a spacer block can be fitted onto the pusher block to increase its height and width or used to change the spacing between the tracks. The tracks are generally freely slidable in races formed within the frame.

Dependent claims

A pusher block and track combination comprising:

a track comprising:
a first raised rail and a second raised rail, said first raised rail and said second raised rail extending generally parallel with each other,
said first raised rail comprising a first product supporting surface and a first bottom surface, said first rail further comprising a first outside edge surface and a first inside edge surface, said first outside edge surface and said first inside edge surface extending between said first product supporting surface and said first bottom surface,
said second raised rail comprising a second product supporting surface and a second bottom surface, said second rail further comprising a second outside edge surface and a second inside edge surface, said second outside edge surface and said second inside edge surface extending between said second product supporting surface and said second bottom surface,
said first inside edge surface and said second inside edge surface being disposed between said first outside edge surface and said second outside edge surface,
a pusher block comprising:
a sliding surface being adapted to slide along said first product supporting surface and said second product supporting surface,
a first outside flange disposed to a first side of said pusher block and adapted to wrap around said first outside edge surface and a portion of said first bottom surface,
a second outside flange disposed to a second side of said pusher block and adapted to wrap around said second outside edge surface and a portion of said second bottom surface,
a T-shaped boss extending below said sliding surface and comprising a first arm and a second arm, said first arm extending below said first rail and said second arm extending below said second rail,
said first and second outside flanges and said first and second arms cooperating such that said pusher block covers at least a portion of said first and second product supporting surfaces, said first and second outside edge surfaces, said first and second inside edge surfaces and said first and second bottom surfaces.

A pusher block and track combination comprising:

a track comprising:
a first raised rail and a second raised rail, said first raised rail and said second raised rail extending generally parallel with each other,
said first raised rail comprising a first top surface, a first bottom surface, a first outside surface and a first inside surface,
said second raised rail comprising a second top surface, a second bottom surface, a second outside surface and a second inside surface,
a pusher block comprising:
a main body comprising a sliding surface adapted to slide along said first and second top surfaces,
a first outside flange, a second outside flange, a first inside flange and
a second inside flange depending from said main body,
said first outside flange extending around said first outside surface and
a portion of said first bottom surface,
said first inside flange extending around said first inside surface and a portion of said first bottom surface,
said second outside flange extending around said second outside surface and a portion of said second bottom surface,
said second inside flange extending around said second inside surface and a portion of said second bottom surface,
such that, together, said main body, said first outside flange and said first inside flange capture said first rail and said main body, said second outside flange and said second inside flange capture said second rail, and wherein the first and second inside flanges are configured to engage portions of the first and second bottom surfaces while the sliding surface engages the first and second top surfaces throughout a sliding motion of the pusher block along the first and second raised rails.
