Concealed vertical adjustment mechanism for kitchen appliance storage members

A storage member vertical adjustment mechanism for a kitchen appliance, the storage member vertical adjustment mechanism comprising:

• an appliance cabinet having a plurality of sidewalls and a back wall that define an interior volume;
• a concealed vertical track system positioned at least within the back wall of the appliance cabinet, the concealed vertical track system including a tubular retaining member defining an inside space, a concealing flange and a transition member that extends between the tubular retaining member and the concealing flange to define an adjustment region therebetween;
• and
• a storage member having an engagement structure that cooperatively engages the adjustment region, wherein the engagement structure includes a laterally extending vertical flange configured to be inserted into and removed from the adjustment region via a top receiving aperture defined proximate a cooling tower of the appliance cabinet, wherein when the laterally extending vertical flange is positioned within the adjustment region, the laterally extending vertical flange extends through a vertical gap to a storage portion of the storage member such that the laterally extending vertical flange is laterally secured within the adjustment region, wherein the laterally extending vertical flange engages an outward surface of the tubular retaining member to define a plurality of vertically secured positions wherein a plurality of protrusions extend at least partially into the inside space, and wherein the laterally extending vertical flange is operable transversely across the adjustment region to define an adjustment state wherein the laterally extending vertical flange is vertically operable within the adjustment region and laterally operable within the adjustment region into any one of the plurality of vertically secured positions.
