The drawers include rollers extending downwardly and outwardly from the drawers to provide maximum storage volume. The rollers are configured to work with channels formed in a support system, which may be integrally formed with a bottom floor of a compartment of the refrigerator. Therefore, the rollers and channels of the support system provide easy access and removability of the drawers of the crisper system. ## Claims ### Claim 1 A refrigerator, comprising: a cabinet; a compartment within the cabinet; at least one door for providing access to the compartment; a support system in the compartment comprising at least two channels extending generally outward therefrom, and a plurality of fixed rollers rotationally coupled to the support system; a drawer forming a storage area, the drawer comprising a plurality of rollers extending away from the storage area and configured to move between the two channels, the at least two channels comprising: a first channel at a first side of the support system, a second channel positioned from the first channel, a third channel positioned from the second channel, and a fourth channel positioned from the third channel at a second side of the support system, and the drawer further comprising: a first drawer positioned between the first and second channels, a second drawer positioned between the second and third channels, and a third drawer positioned between the third and fourth channels, wherein the fixed rollers are configured to support the drawers such that the rollers coupled to the support system are inboard of the rollers on the drawers. ### Claim 2 (depends on 1) The refrigerator of claim 1 wherein the support system is formed integrally with the compartment. ### Claim 3 (depends on 2) The refrigerator of claim 2 wherein the support system is formed as a bottom wall of the compartment. ### Claim 4 (depends on 1) The refrigerator of claim 1 wherein the channels comprise a wall extending outward from the support system and a lip extending generally inward from the wall. ### Claim 5 (depends on 1) The refrigerator of claim 1 wherein the drawers comprise a bottom wall, first, second, and third walls extending from the bottom wall, and a front wall extending from the bottom wall. ### Claim 6 (depends on 5) The refrigerator of claim 5 wherein the front wall includes a handle configured to aid in the movement of the rollers of the drawer within the channels. ### Claim 7 (depends on 1) The refrigerator of claim 1 wherein the channels comprise a lock at the front of the support system to removably hold the respective drawer in the support system. ### Claim 8 (depends on 1) The refrigerator of claim 1, wherein the fixed rollers are configured to move vertically upon removal of the respective drawer from the refrigerator. ### Claim 9 A refrigerator, comprising: a refrigerator compartment comprising a support system formed as part of a bottom wall of said compartment, the support system comprising a plurality of channels and fixed rollers; and at least one drawer positioned at the support system and including a plurality of rollers extending outwardly and downwardly from a portion of the drawer; wherein the rollers of the drawer are configured to be placed in the channels of the support system to aid in the movement of the drawer relative to the refrigerator compartment, and the plurality of channels comprising: a first channel at a first side of the support system, a second channel positioned from the first channel, a third channel positioned from the second channel, and a fourth channel positioned from the third channel at a second side of the support system, the at least one drawer comprising: a first drawer positioned between the first and second channels, a second drawer positioned between the second and third channels, and a third drawer positioned between the third and fourth channels, wherein the fixed rollers are located inboard of the rollers of the drawers and are configured to move vertically upon removal of the drawers from the refrigerator. ### Claim 10 (depends on 9) The refrigerator of claim 9 further comprising a shelf positioned within the compartment and defining a lid of the at least one drawers. ### Claim 11 (depends on 9) The refrigerator of claim 9 wherein the channels comprise a generally vertical wall and a lip generally perpendicular to the wall. ### Claim 12 (depends on 9) The refrigerator of claim 9 wherein the channels comprise a lock at the front of the support system to removably hold the respective drawer in the support system. ### Claim 13 (depends on 12) The refrigerator of claim 12 wherein the lock comprises an indent and a raised portion of the channel. ### Claim 14 A crisper system including a support system and drawer for use in a compartment of a refrigerator, comprising: abase; a plurality of fixed rollers rotationally coupled to the base; a drawer comprising a storage area and a plurality of wheels extending from the storage area, the wheels configured to move under a lip and adjacent a wall, a first channel at a first side of the base, a second channel positioned from the first channel, a third channel positioned from the second channel, and a fourth channel positioned from the third channel at a second side of the base, and the drawer further comprising: a first drawer positioned between the first and second channels, a second drawer positioned between the second and third channels, and a third drawer positioned between the third and fourth channels, wherein the fixed rollers are disposed inboard of the rollers on the drawers and are configured to move vertically upon removal of the drawers from the refrigerator. ### Claim 15 (depends on 14) The crisper system of claim 14 wherein the channels further comprise a lock along the length of the channel to selectively maintain the wheels in the channels. ### Claim 16 (depends on 15) The crisper system of claim 15 wherein the lock comprises an indent and a raised portion of the channel. ### Claim 17 (depends on 16) The crisper system of claim 16 wherein the drawers can be removed from the channels at the lock.
