Abstract

A refrigerator shelf assembly includes a frame having a depth and a first support element extending along the depth and defining a first track open in a lateral direction perpendicular to the depth. The support element further defines a first open area along a first side of the track and extending between an adjacent portion of the track and an exterior of the first support element and a cantilever arm having a free end adjacent the first open area. The cantilever arm is resiliently deformable away from a plane defined along the first side of the track. The assembly further includes an insert slidably received within the track and moveable along the depth of the first track through a fixed range of motion, wherein the insert is disposed over an expanse of the first open area.

First claim

What is claimed is:

1. A refrigerator shelf assembly, comprising:
a frame having a depth, a first support element extending along the depth and opposite first and second closed ends defining a length of the first track, the first support element further defining a first track open in a lateral direction perpendicular to the depth, the support element further defining a first open area along a first side of the support element perpendicular to the lateral direction and the depth and extending between an adjacent portion of the first track and an exterior of the first support element and a cantilever arm having a free end adjacent the first open area, the cantilever arm being resiliently deformable away from a plane defined along the first side of the first support element; and
an insert slidably received within the first track and moveable along the plane in a direction of the depth of the first track through a fixed range of motion wherein the insert is disposed over an entirety of the first open area within at least a portion of the fixed range of motion, the fixed range of motion of the insert being defined between an extended position, wherein a front edge of the insert is adjacent the first end of the first track and a back edge of the insert is remote from the second end of the first track, and a tucked position, wherein the front edge of the insert is spaced from the first end of the first track by a first distance equal to a second distance between the front and back edges of the insert and the back edge of the insert is spaced from the second end of the first track.

2. The shelf assembly of claim 1 , wherein:
the first open area is defined between a front edge and a back edge defined on a free end of the cantilever arm, the front edge being disposed toward the first end of the first track and the back edge being disposed toward the second end of the first track; and
a first distance between the back edge of the insert and the second end of the first track is greater than a second distance between the front edge of the insert and the front edge of the first open area throughout the fixed range of motion of the insert.

3. The shelf assembly of claim 1 , wherein:
the insert is configurable in an installed state, wherein movement thereof along the first track is restricted to movement within the fixed range of motion; and
the insert is further configurable in an assembly state, wherein movement thereof along the entirety of the first track is permitted.

4. The shelf assembly of claim 3 , wherein movement along the entirety of the first track includes movement of the back edge of the insert into contact with the second end of the first track.

5. The shelf assembly of claim 3 , wherein the insert is alternately configurable in the installed state and the assembly state by a trim piece being assembled or disassembled with the front edge of the insert.

6. The shelf assembly of claim 5 , wherein:
the frame further includes an intermediate support extending from midpoint of the first support element perpendicularly thereto; and
the trim piece contacts the intermediate support when installed on the insert in the tucked position to restrict movement of the insert to within the fixed range of motion.

7. The shelf assembly of claim 3 , wherein when in the assembly state, the insert is moveable through the first open area into and out of an assembly position wherein the back edge of the insert is in contact with the second end of the first track.

8. The shelf assembly of claim 7 , wherein the insert is moveable through the first open area into and out of the assembly position by rotation of the insert generally about the back edge thereof under extension and flexing of the cantilever arm.

9. A refrigerator shelf assembly, comprising:
a frame having a depth and a first support element extending along the depth and defining a first linear track, a first open area extending between an adjacent portion of the first track and an exterior of the first support element, and a resiliently deformable cantilever arm having a free end adjacent the first open area; and
an insert the insert configurable in an installed state, wherein the first track is slideable along the first track within an installed fixed range of motion less than a full length of the first linear track, and in an assembly state, wherein movement thereof along the full length of the first linear track along a horizontal plane is permitted;
wherein when in the assembly state, the insert is moveable through the first open area into and out of an assembly position wherein the back edge of the insert is in contact with the second end of the first track by rotation of the insert generally about the back edge thereof under extension and flexing of the cantilever arm.

10. The shelf assembly of claim 9 , wherein the insert is alternately configurable in the installed state and the assembly state by a trim piece being assembled or disassembled with the front edge of the insert.

11. The shelf assembly of claim 10 , wherein:
the frame further includes an intermediate support extending from midpoint of the first support element perpendicularly thereto; and
the trim piece contacts the intermediate support when installed on the insert in the tucked position to restrict movement of the insert to within the fixed range of motion.

12. The shelf assembly of claim 9 , wherein the support element is a first support element, the open area is a first open area, and the frame further includes:
a second support element opposite the first support element and extending along the depth generally parallel with the first support element, the second support element defining a second first track facing the first track; and
an intermediate support extending between the first and second support elements perpendicular thereto and spaced at a midpoint along the depth of the frame; and
the assembly further includes a first substrate supported on the intermediate support and the first and second support elements in a fixed position.

13. The shelf assembly of claim 12 , wherein movement of the insert, when in the installed state, through the fixed range of motion includes movement of the insert into a tucked position, wherein the first substrate overlies the insert and an extended position, wherein the insert extends in a portion of the depth outside of the first substrate.

14. The shelf assembly of claim 13 , wherein the frame further defines first and second lateral elements spaced outwardly from and generally parallel with the first and second support elements through the depth of the frame, the first and second lateral elements defining a width of the frame that is greater than a distance between the first and second support elements, the assembly further including:
second and third substrates, the second substrate being positioned in an area between the first lateral element and the first support element and the third substrate being positioned in an area between the second lateral element and the second support element, both the second and third substrates extending through a majority of the depth of the frame.

15. The shelf assembly of claim 9 , wherein, when the insert is in the installed state, the insert is disposed over an expanse of the first open area throughout sliding of the insert along the first track within the fixed range of motion.

16. A refrigerator shelf assembly, comprising:
a frame defining a depth and including:
a first support element extending along the depth and defining a first track open in a lateral direction perpendicular to the depth, the
