Abstract

A storage member vertical adjustment mechanism for an appliance includes a concealed vertical track system that is positioned within an appliance cabinet. The vertical track system includes a retaining member and a concealing flange that extends parallel with and conceals the retaining member with an adjustment region defined therebetween. A storage member has an engagement structure that cooperatively engages the adjustment region. The engagement structure includes a laterally-extending vertical flange that engages the concealing flange and the retaining member in a vertical adjustment state and alternatively engages the retaining member in the vertically secured positions. The retaining member and the concealing flange laterally support the laterally-extending vertical flange within the adjustment region such that the engagement structure of the storage member is selectively inserted and removed from the adjustment region through one of the top and bottom receiving apertures of the adjustment region.

First claim

The invention claimed is:

1. 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 proximate the back wall of the appliance cabinet and including a tubular retaining member and a concealing flange, wherein an adjustment region is defined between an outward surface of the tubular retaining member and an inward surface of the concealing flange that define at least a top receiving aperture; and
a storage member having an engagement structure that cooperatively engages the adjustment region and includes a laterally extending vertical flange that operates laterally within the adjustment region to alternatively and selectively define a vertically slidable adjustment state and a plurality of vertically secured positions, and wherein the tubular retaining member and the concealing flange laterally support the laterally extending vertical flange within the adjustment region such that the engagement structure of the storage member can be selectively inserted and removed from the adjustment region only via at least one of a top receiving aperture and a bottom receiving aperture of the adjustment region, wherein the each vertically secured position is further defined by at least two vertically aligned protrusions of the engagement structure extending at least partially into an inside space of the tubular retaining member.

2. The storage member vertical adjustment mechanism of claim 1 , wherein the tubular retaining member includes a plurality of retaining apertures defined therein, and wherein the at least two vertically aligned protrusions are selectively received by a portion of the plurality of retaining apertures to define the plurality of vertically secured positions, and wherein movement of the engagement structure to the vertically slidable adjustment state serves to disengage the at least two vertically aligned protrusions from corresponding retaining apertures such that the engagement structure can be vertically operated within the adjustment region.

3. The storage member vertical adjustment mechanism of claim 2 , wherein the at least two vertically aligned protrusions of the engagement structure includes three vertically aligned protrusions that are separated by a first distance, wherein the plurality of retaining apertures are spaced apart by a second distance, wherein the first distance is the same as the second distance, and wherein each of the vertically secured positions is further defined by the at least two vertically aligned protrusions of the three vertically aligned protrusions being engaged with corresponding retaining apertures, and wherein when the engagement structure defines the vertically slidable adjustment state when the at least two vertically aligned protrusions are out of engagement with the corresponding retaining apertures such that the engagement structure is substantially free to slidably operate within the adjustment region.

4. The storage member vertical adjustment mechanism of claim 1 , wherein each of the plurality of vertically secured positions is defined by the engagement structure being substantially parallel with the concealing flange and the tubular retaining member, and wherein the vertically slidable adjustment state is defined by the engagement structure being rotated to be out of parallel with the concealing flange and the tubular retaining member.

5. The storage member vertical adjustment mechanism of claim 1 , wherein the tubular retaining member and the concealing flange are connected by a transition member, and wherein the tubular retaining member, the concealing flange and the transition member are part of a unitary co-extruded track member.

6. The storage member vertical adjustment mechanism of claim 5 , wherein the concealed vertical track system includes two opposing co-extruded track members and wherein the engagement structure of the storage member includes first and second laterally extending vertical flanges that cooperatively engage the two opposing co-extruded track members, respectively.

7. The storage member vertical adjustment mechanism of claim 6 , wherein the first and second laterally extending vertical flanges are co-planar and extend toward one another to engage the two opposing co-extruded track members, respectively, and wherein the storage member is a storage bin having a bracket that includes the engagement structure.

8. The storage member vertical adjustment mechanism of claim 1 , wherein the storage member is a shelf that extends into the interior volume of the appliance cabinet.

9. The storage member vertical adjustment mechanism of claim 1 , wherein the concealing flange is at least partially defined by a cooling tower of the appliance cabinet.

10. A storage member vertical adjustment mechanism comprising:
a concealed vertical track system configured to be incorporated into a kitchen appliance, the concealed vertical track system including a tubular retaining member that is co-extruded with a concealing flange to define an adjustment region, wherein a plurality of securing structures are defined within the tubular retaining member and are in communication with the adjustment region, and wherein the concealing flange at least partially conceals the plurality of securing structures from view; and
at least one storage member having an engagement structure that cooperatively engages the adjustment region of the concealed vertical track system, wherein the engagement structure includes a laterally extending vertical flange that operates transversely within the adjustment region to selectively and alternatively define a vertical adjustment state and a plurality of vertically secured positions, and wherein the concealed vertical track system includes two opposing co-extruded track members and wherein the engagement structure of the at least one storage member includes first and second laterally extending vertical flanges that are co-planar and extend toward one another to cooperatively engage the two opposing co-extruded track members, respectively.

11. The storage member vertical adjustment mechanism of claim 10 , wherein the tubular retaining member and the concealing flange define a slot through which the engagement structure can vertically operate within the adjustment region, a vertical slot having a slot width that is less than a thickness of the engagement structure such that the engagement structure of the at least one storage member is selectively inserted and removed from the adjustment region only via at least one of a first end and a second end of the adjustment region.

12. The storage member vertical adjustment mechanism of claim 10 , wherein the tubular retaining member includes an extruded tubular structure that defines an inside space, wherein the each vertically secured position is further defined by at least two vertically aligned protrusions extending at least partially into the inside space of the extruded tubular structure, and wherein the extruded tubular structure and the concealing flange are connected by a transition member, and wherein the extruded tubular structure, the concealing flange and the transition member are part of a unitary and co-extruded track member.

13. The storage member vertical adjustment mechanism of claim 12 , wherein the tubular retaining member and the concealing flange are connected by the transition member, and wherein the tubular retaining member, the concealing flange and the transition member are part of the unitary co-extruded track member.
