Abstract: An adjustable shelf system for a household appliance includes at least one shelf assembly having at least one support structure, wherein each support structure of the shelf assembly includes upper and lower coupling elements outwardly extending from the support structures. A track member is coupled to a sidewall of an internal compartment of the appliance. The track member includes an outer surface with at least one longitudinal channel disposed therein. The longitudinal channel further includes a plurality of spaced-apart receiving notches disposed along a vertical length the channel. The upper and lower coupling elements of the support structures are configured to be received in the longitudinal channels of the track members and nested within the receiving notches thereof.

Abstract: A mobile shelf is horizontal and displaceably mounted in rails fixed to the cabinet of refrigerator or freezer, inwardly to a refrigerator chamber. The shelf comprises an actuator device operatively associated to the shelf and cabinet. The actuator device is driven to an inoperative armed position, achieved when the shelf is displaced backwards, to a retracted position, and an operative distended position, in which the shelf is displaced forward, to a forward position. The actuator device is actuated, from the inoperative armed position to an operative distended position, when applying a manual instantaneous axial force backwards, against the shelf.
