a connecting link extending between and coupling the second end portions of said pair of mobile link arms together
an anti-racking mechanism mounted to said housing below the bottom wall of said container and configured for assisting said pair of fixed link arms with rotating at a common angular velocity; wherein said anti-racking mechanism comprises:
a pair of tracks mounted to said housing at opposing sides of said housing such that said pair of tracks are spaced apart from one another along the lateral direction, said pair of tracks extending longitudinally along the transverse direction;
a pair of gears, each gear of said pair of gears engaging a respective one of said pair of tracks; and
a shaft extending between and coupling said pair of gears together.
2. The refrigerator appliance of claim 1 , further comprising a plurality of anti-friction mechanisms disposed on a top surface of at least one of said pair of fixed link arms and said pair of mobile link arms.
3. The refrigerator appliance of claim 2 , wherein said plurality of anti-friction mechanisms is disposed between the bottom wall of said container and the top surface of at least one of said pair of fixed link arms and said pair of mobile link arms in order assist said container with moving along the transverse direction.
4. The refrigerator appliance of claim 1 , further comprising a frame for supporting said container, said frame comprising:
a pair of transverse members mounted to said connecting link and extending longitudinally along the transverse direction; and
a lateral member extending longitudinally along the lateral direction, said lateral member also extending between and connecting said pair of transverse members.
5. The refrigerator appliance of claim 4 , wherein said container is mounted to said frame.
6. The refrigerator appliance of claim 1 , wherein said shaft is rotatably mounted to said pair of fixed link arms or said pair of mobile link arms.
7. The refrigerator appliance of claim 1 , wherein said housing defines a pair of channels that extend into said housing along the vertical direction, each mobile link arm of said pair of mobile link arms having a boss mounted thereto, each boss received within a respective one of said pair of channels.
8. The refrigerator appliance of claim 7 , wherein each channel of said pair of channels extends arcuately along the lateral and transverse directions between a first end portion and a second end portion.
9. A drawer assembly for an appliance, the drawer assembly defining a vertical direction, a lateral direction, and a transverse direction, the vertical, lateral, and transverse directions being mutually perpendicular, the drawer assembly, comprising:
a container defining a storage volume for receipt of items for storage, said container having a bottom wall;
a linkage assembly positioned below the bottom wall of said container along the vertical direction, said container supported by said linkage assembly such that said container is moveable along the transverse direction on said linkage assembly, said linkage assembly comprising
a base;
a pair of fixed link arms spaced apart from one another along the lateral direction, each fixed link arm of said pair of fixed link arms extending between a first end portion and a second end portion, the first end portions of said pair of fixed link arms rotatably mounted to said base;
a pair of mobile link arms spaced apart from one another along the lateral direction, each mobile link arm of said pair of mobile link arms extending between a first end portion and a second end portion, each first end portion of said pair of mobile link arms rotatably mounted to a respective second end portion of said pair of fixed link arms; and
a connecting link extending between and coupling the second end portions of said pair of mobile link arms together
an anti-racking mechanism mounted to said base below the bottom wall of said container and configured for assisting said pair of fixed link arms with rotating at a common angular velocity; wherein said anti-racking mechanism comprises:
a pair of tracks mounted to said base at opposing sides of said base such that said pair of tracks are spaced apart from one another along the lateral direction, said pair of tracks extending longitudinally along the transverse direction;
a pair of gears, each gear of said pair of gears engaging a respective one of said pair of tracks; and
a shaft extending between and coupling said pair of gears together.
10. The drawer assembly of claim 9 , further comprising a plurality of anti-friction mechanisms disposed on a top surface of at least one of said pair of fixed link arms and said pair of mobile link arms.
11. The drawer assembly of claim 10 , wherein said plurality of anti-friction mechanisms is disposed between the bottom wall of said container and the top surface of at least one of said pair of fixed link arms and said pair of mobile link arms in order assist said container with moving along the transverse direction.
12. The drawer assembly of claim 9 , further comprising a frame for supporting said container, said frame comprising
a pair of transverse members mounted to said connecting link and extending longitudinally along the transverse direction; and
a lateral member extending longitudinally along the lateral direction, said lateral member also extending between and connecting said pair of transverse members.
13. The drawer assembly of claim 12 , wherein said container is mounted to said frame.
14. The drawer assembly of claim 9 , wherein said shaft is rotatably mounted to said pair of fixed link arms or said pair of mobile link arms.
15. The drawer assembly of claim 9 , wherein said base defines a pair of channels that extend into said base along the vertical direction, each mobile link arm of said pair of mobile link arms having a boss mounted thereto, each boss received within a respective one of said pair of channels.
