In the preferred form the present invention is directed to a cavity having a side opening and a rack adapted so as to be rotatable between a position within the cavity and a position outside of the cavity. The rack is mounted on a threaded member having a vertical axis whereby rotation of the threaded member causes the rack to pivot between the two aforesaid positions and further rotation of the vertical adjustment member causes said rack to be vertically displayed with respect to the cavity.

A rack adjustment mechanism for a cabinet having a plurality of walls defining a chamber, the combination comprising a vertically disposed threaded member mounted for rotation with respect to said cabinet, a rotatable member mounted with respect to said cabinet to impart at least limited rotation to said threaded member, an object supporting rack carried by said threaded member for disposition within said chamber, said rack frictionally cooperating with said threaded member whereby rotation of said threaded member frictionally imparts rotation to said rack to horizontally displace an object supported by said rack with respect to said chamber, and said rack cooperates with a wall of said chamber to limit rotation of said rack whereby further rotation of said threaded member causes said rack to engage said wall to limit rotation of said rack and overcome the frictional cooperation between said rack and said threaded member to cause vertical shifting of said rack along the axis of said threaded member to vary the vertical position of an object supported by said rack with respect to said chamber.
