A closure assembly configured to urge a drawer of a refrigerator from an open position that permits access to an interior of the drawer toward a closed position that impedes access to the interior of the drawer. The closure assembly includes a cam block configured to be disposed on one of the drawer
A closure assembly configured to urge a drawer of a refrigerator from an open position that permits access to an interior of the drawer toward a closed position that impedes access to the interior of the drawer. The closure assembly includes a cam block configured to be disposed on one of the drawer and a portion of the refrigerator other than the drawer. The cam block includes a cam surface. A cam member is configured to be disposed on the other one of the drawer and the portion of the refrigerator other than the drawer. The cam member includes a contact surface configured to contact the cam surface to urge the drawer from the open position toward the closed position.

The invention claimed is: 1. A refrigerator comprising: a drawer; and a closure assembly comprising: a cam block disposed on one of the drawer and a portion of the refrigerator other than the drawer, the cam block comprising a first cam surface and a second cam surface; and a cam member disposed on
The invention claimed is: 1. A refrigerator comprising: a drawer; and a closure assembly comprising: a cam block disposed on one of the drawer and a portion of the refrigerator other than the drawer, the cam block comprising a first cam surface and a second cam surface; and a cam member disposed on the other of the drawer and the portion of the refrigerator other than the drawer, the cam member comprising a contact surface, wherein when the drawer is opened less than a first predetermined linear distance, the contact surface is biased to engage the first cam surface so that the contact surface and the first cam surface cooperate with each other to apply a closing force on the drawer, and wherein when the drawer is opened more than the first predetermined linear distance, the contact surface is biased to engage the second cam surface and the contact surface and the second cam surface cooperate with each other to generate an opening force on the drawer. 2. The refrigerator of claim 1, wherein the cam member comprises a lever arm rotatable about an axis. 3. The refrigerator of claim 2, further comprising a resilient member biasing the contact surface toward the cam block. 4. The refrigerator of claim 3, wherein the resilient member comprises a spring. 5. The refrigerator of claim 3, wherein the lever arm comprises a first end, a second end, and a wheel member mounted on the first end and comprising the contact surface, the axis being disposed between the first end and the second end, the second end being connected to the resilient member. 6. The refrigerator of claim 2, wherein the cam member further comprises a wheel member disposed on the lever arm, the wheel member comprising the contact surface. 7. The refrigerator of claim 1, wherein the cam block is disposed on the drawer and the cam member is disposed on the portion of the refrigerator other than the drawer. 8. The refrigerator of claim 1, wherein when the drawer is opened more than a second predetermined linear distance greater than the first predetermined linear distance, the contact surface does not engage the cam block so that neither a closing force nor an opening force is applied on the drawer. 9. An apparatus comprising: a drawer; and a closure assembly comprising: a cam block disposed on one of the drawer and a portion of the apparatus other than the drawer, the cam block comprising a first cam surface and a second cam surface; and a cam member disposed on the other of the drawer and the portion of the apparatus other than the drawer, the cam member comprising a contact surface, wherein when the drawer is opened less than a first predetermined linear distance, the contact surface is biased to engage the first cam surface, and the contact surface and the first cam surface cooperate with each other to apply a closing force on the drawer, and wherein when the drawer is opened more than the first predetermined linear distance, the contact surface is biased to engage the second cam surface, and the contact surface and the second cam surface cooperate with each other to generate an opening force on the drawer. 10. The apparatus of claim 9, wherein the cam member comprises a lever arm rotatable about an axis. 11. The apparatus of claim 10, further comprising a resilient member biasing the contact surface toward the cam block. 12. The apparatus of claim 11, wherein the resilient member comprises a spring. 13. The apparatus of claim 11, wherein the lever arm comprises a first end, a second end, and a wheel member mounted on the first end and comprising the contact surface, the axis being disposed between the first end and the second end, the second end being connected to the resilient member. 14. The apparatus of claim 10, wherein the cam member further comprises a wheel member disposed on the lever arm, the wheel member comprising the contact surface. 15. The apparatus of claim 10, wherein the apparatus is a refrigerator. 16. The apparatus of claim 9, wherein the cam block is disposed on the drawer and the cam member is disposed on the portion of the refrigerator other than the drawer. 17. The apparatus of claim 9, wherein when the drawer is opened more than a second predetermined linear distance greater than the first predetermined linear distance, the contact surface does not engage the cam block so that neither a closing force nor an opening force is applied on the drawer.
