Depth and width adjustable display track unit with removable partitions

In combination, an integrally molded display floor devoid of integrally molded side walls upstanding therefrom, comprising:

• (a) opposite front and rear ends,
• (b) a plurality of laterally spaced apart longitudinally extending ribs connected to said front and rear ends with a longitudinal slot defined between each two adjacent ribs, said ribs having top surfaces which define a top plane of said floor at a first level for supporting products to slide thereon and bottom surfaces which define a second level below said first level,
• (c) a pair of opposite side walls connected to said front and rear ends, said side walls having bottom surfaces at a third level below said second level, and
• (d) a plurality of longitudinally spaced beams extending transversely between said side walls and intersecting and joining said ribs, said beams having top surfaces at a fourth level below said first level and having bottom surfaces,
• said side walls, front and rear walls and bottom surfaces of said ribs defining a basement where said bottom surfaces of said ribs and bottom surfaces of said beams define a discontinuous ceiling of said basement, at least two longitudinally extending partitions, each partition comprising a panel with a lower edge, said partitions being attachable in upstanding orientation to said display floor and removable therefrom, said partitions when attached to said display floor being transversely separated from each other and defining between them a travel path for said products on said top surfaces along said floor, each of said partitions further comprising first coupling means at the lower edge of said panel,
• said display floor further comprising a plurality of second coupling means, each adapted to receive one of said first coupling means to engage and releasably restrain a partition from disengagement from said display floor, said partition further comprises a spring finger having a first, relaxed position where it engages said display floor and bars said partition from moving in at least one longitudinal direction, and thus bars said first and second couplings from becoming disengaged, and a second, flexed position where it is disengaged from said display floor and allows said partition to move longitudinally and allows said first and second coupling means to become disengaged, wherein said spring finger is an integrally molded part of said partition and includes a trigger part pullable by a user to move said finger from said relaxed to said flexed position.
