The present invention is an adjustable refrigeration display rack arranged to support produce on a refrigerated produce case for display. The adjustable display rack includes a telescopic frame carrying a support rack and anchors for securing the frame to the refrigerated produce case. The display rack further includes a multi-section shelf unit comprising a plurality of shelf sections connected in end to end relation. One of the shelf sections is slidably mounted on the frame. The other shelf sections are supported above the frame by legs pivotally carried by the shelf sections. The support legs have a free end arranged to releasably engage selected teeth of the support rack to support the shelf sections on the frame in a selected angular orientation.

A two-piece telescoping shelf adaptor construction adaptable to be supported on a shelf structure in a flat or inclined position and adjustable to accommodate varying shelf depths comprising first and second members each being formed having a similar number of spaced parallel adjacent guide channels extending thereacross, the first member having a front wall extending across the front edge thereof and the second member having a rear wall extending across the rear edge thereof, the guide channels each including a floor portion and spaced upstanding wall portions extending across the first and second members to form separators between the adjacent channels, the upstanding wall portions on the second member having cross-sectional shapes and being spaced to slidably receive and telescopingly cooperate with the upstanding wall portions on the first member whereby the first and second members can be moved relative to each other in order to achieve a desired length between the front wall of the first member and the rear wall of the second member, and at least one track member positioned in and extending along each of the channels in each of the first and second members to engage and support products positioned thereon, the floor portion associated with each of the adjacent guide channels also including a plurality of apertures located adjacent to the respective track members positioned therein for enabling air to pass therethrough for circulation around the rows of products positioned in each of the guide channels. These constructions can include self-lubricating tracks and can be used by inclining existing shelves to effect gravity feeding of products of various types, sizes and shapes.

A shelf assembly for displaying produce such as prepackaged salads wherein the shelf assembly includes at least two panels and two telescoping arms. The panels are movably supported by the arms with one of the panels at least partially overlapping the other panel. Each of the panels is provided with a plurality of spaced apart apertures extending therethrough. When the panels are arranged to overlap one another, the apertures in the panels align with one another to permit air to circulate therethrough.

An adjustable-length shelf which may be removably mounted in an enclosure, such as a locker cabinet. The shelf is adjustable between a semi-collapsed position to facilitate placement of the shelf within the enclosure and a deployed position for supporting a load at the desired vertical height. The shelf includes a first section having first gripping surface for frictionally engaging one of the enclosure sidewalls, a second section pivotably coupled to the first section, and a third section releasably coupled to the second section and having a second gripping surface for frictionally engaging the other of the enclosure sidewalls.

A legless shelf assembly for use in a locker to provide support for articles to be stored in the locker. The shelf assembly has first and second shelf members movably relative to each other to expanded and retracted positions. Releasable cooperating rachet teeth on the side walls of the shelf members retain the shelf members in their expanded positions. An actuator cam rotatably mounted on one of the shelf members cooperates with teeth on the other of the shelf members to move the shelf members in opposite directions and further retain the shelf members in their expanded positions in tight engagement with the side walls of the locker.
