Returning now to FIG. 2, the frame 62 includes a support bracket 246 configured to receive the pan body 182 of the middle pan 70. In the illustrative embodiment, the support bracket 246 is formed from injection molded polypropylene that is opaque or colored. In other embodiments, the support bracket 246 may be formed from a clear or frosted polymeric material. As shown in FIG. 2, the support bracket 246 has a bottom wall 342 and a plurality of outer walls 344 that extend upwardly from the bottom wall 342. The walls 342, 344 cooperate to define a compartment 346 in the bracket 246. An open front side 348 of the bracket 246 defines an access opening 350 sized to receive the pan body 182 of the middle pan 70.

The outer walls 342 of the support bracket 246 include a rear plate 352 and a pair of side plates 354, 356 that extend between the front side 348 of the bracket 246 and the rear plate 352.

A plurality of support ribs 384 extend between the bottom wall 342 and the bottom surface 382 of each lower flange 372. When the middle pan 70 is coupled to the support bracket 246, the roller 230 is positioned between the flanges 370, 372 and is configured to roll along the surfaces 374, 378 of the flanges 370, 372, respectively, as the middle pan 70 is moved between the extended position and the retracted position.

As shown in FIG. 2, a pair of rollers 390 is secured to the bottom wall 342 of the bracket 246 adjacent to the front side 268. Each roller 390, like the rollers 120 of the side pans 72, 74, has a cylindrical outer surface 392 and a groove 394 defined therein, and each roller 390 is configured to rotate about an axis 396. When the middle pan 70 is coupled to the support bracket 246, the rollers 390 engage the bottom surfaces 216 of the flanges 210, 212 of the middle pan 70. As the middle pan 70 is moved between the extended position and the retracted position, the engagement between the flanges 210 of the middle pan 70 and the rollers 390 of the support bracket 246 causes the rollers 390 to be rotated about their respective axes 396.

The support bracket 246 of the frame 62 includes an outer roller support 398 extending from the outer surface 364 of the side plate 356 and another outer roller support 400 (see FIG. 6) extending from the outer surface 364 of the side plate 354. Each of the roller supports 398, 400 is sized to receive one of the rollers 120 of the side pans 72, 74. The outer roller support 398 is described in greater detail below, but it should be appreciated that, in the illustrative embodiment, the outer roller support 400 has a configuration that mirrors the configuration of the outer roller support 398.

As shown in FIG. 9, the outer roller support 398 of the support bracket 246 is defined by a lower flange 402 and an upper flange 404 positioned above the lower flange 402. The lower flange 402 includes an upper surface 406 and a lower surface 408 positioned opposite the upper surface 406. A plurality of support ribs 384 extend between the outer surface 364 of the side plate 356 and the lower surface 408 of each lower flange 402. The upper surface 406 of the lower flange 402 includes a front section 410, a rear section 412, and a middle section 414 connecting the sections 410, 412. As shown in FIG. 9, the sections 410, 412 extend substantially horizontally and the middle section 414 of the upper surface 406 is slanted or inclined. The middle section 414 has a lower end 416 connected to the front section 410 and an upper end 418 connected to the rear section 412.

The upper flange 404 of the support bracket 246 has a lower surface 420 that extends parallel to the rear section 412 of the upper surface 406 of the lower flange 402. A tab 422 extends downwardly from the lower surface 420 of the upper flange 404 toward the upper surface 406 of the lower flange 402. In the illustrative embodiment, the tab 422 is aligned vertically with the lower end 416 of the middle section 414 of the upper surface 406.

Returning to FIG. 2, the support bracket 246 also includes a pair of rollers 430 that are secured to the outer surfaces 364 of the side plates 354, 356, respectively. A roller housing 432 extends outwardly from each of the side plates 354, 356 adjacent to the front side 348 of the support bracket 246. Each roller 430 is positioned in a slot 434 defined in each housing 432.

As shown in FIG. 4, each roller 430 has a body 436 including a cylindrical outer surface 438. In the illustrative embodiment, the outer surface 438 of each roller 430 is substantially smooth. The body 436 of each roller 430 is attached to the support bracket 246 via a joint 440. The joint 440 includes a cylindrical pin 442 that extends from the body 436. The pin 442 is received in a pair of slots 444 defined in the housing 432. The roller 430 is configured to rotate about an axis 446 defined by the pin 442.

Referring now to FIG. 6, the crisper pans 64 are shown positioned in the frame 62. The pan body of the side pan 72 is positioned between the support bracket 246 and the mounting plate 242, and pan body of the side pan 74 is positioned between the support bracket 246 and the mounting plate 242. The roller 122 of the side pan 72 is positioned in the guide track 282 of the mounting plate 242, and the roller 124 of the side pan 72 is positioned in the outer roller support 398 of the support bracket 246. As shown in FIG. 6, the cylindrical outer surface 128 of the roller 122 engages the upper surface 290 of the lower flange 284 and the lower surface 304 of the upper flange 286 of the mounting plate 242.

The guide track 282 of the mounting plate 242 includes the guide rails 310, 312, which extend from the surfaces 290, 304, respectively. As shown in FIG. 6, the guide rails 310, 312 are positioned in the groove 136 of the roller 122. Additionally, the side pan 72 also has a lower flange 152, which is engaged with the roller 326 of the mounting plate 242. The bottom surface 162 of the lower flange 152 engages the cylindrical outer surface 328 of the roller 326. The side pan 72 also includes a guide rail 170 that extends downwardly from the lower flange 152. The guide rail 170 is received in the groove 334 of the roller 326. The engagement between the guide rail 170 and the roller 326 together with the engagement between the roller 122 and the guide rails 310, 312 guides or directs the movement of the side pan 72 as the side pan 72 is advanced between the retracted position and the extended position. In that way, the rollers 122, 326 and the guide rails 170, 310, 312 act as a guide system for the side pan 72.

As shown in FIG. 6, the roller 124 of the side pan 72 is positioned in the outer roller support 398 of the support bracket 246. The cylindrical outer surface 128 of the roller 124 engages the upper surface 406 of the lower flange 402 and the lower surface 408 of the upper flange 404. As described above, the side pan 72 also includes a guide rail 172, which is engaged with the roller 430 of the support bracket 246. As shown in FIG. 6, the bottom surface 176 of the guide rail 172 engages the cylindrical outer surface 438 of the roller 430.

The other side pan 74 of the pan system 60 is positioned between the support bracket 246 and the other mounting plate 244 of the frame 62. The roller 124 of the side pan 74 is positioned in the guide track 282 of the mounting plate 244 and the roller 122 of the side pan 74 is positioned in the outer roller support 400 of the support bracket 246. The cylindrical outer surface 128 of the roller 124 engages the upper surface 290 of the lower flange 284 and the lower surface 304 of the upper flange 286 of the mounting plate 244. The mounting plate 244, like the mounting plate 242, also includes a guide track 282 and a pair of guide rails 310, 312 that extend from the surfaces 290, 304, respectively, of the mounting plate 244.

As shown in FIG. 6, the guide rails 310, 312 are positioned in the groove 136 of the roller 124 of the side pan 74. Additionally, the side pan 74 has a lower flange 154, which is engaged with the roller 326 of the mounting plate 244. The bottom surface 162 of the lower flange 154 engages the cylindrical outer surface 328 of the roller 326. The side pan 74, like the side pan 72, includes a guide rail 172 that extends downwardly from the lower flange 154. The guide rail 172 of the side pan 74 is received in the groove 334 of the roller 326. The engagement between the guide rail 172 and the roller 326 together with the engagement between the roller 124 and the guide rails 310, 312 guides or directs the movement of the side pan 74 as the side pan 74 is advanced between the retracted position and the extended position. In that way, the rollers 124, 326 and the guide rails 172, 310, 312 act as a guide system for the side pan 74.

As shown in FIG. 6, the roller 122 of the side pan 74 is positioned in the outer roller support 400 of the support bracket 246. The cylindrical outer surface 128 of the roller 122 engages the upper surface 406 of the lower flange 402 and the lower surface 408 of the upper flange 404. The side pan 74, like the side pan 72, includes a guide rail 170 that extends from the lower flange 152. As shown in FIG. 6, the bottom surface 176 of the guide rail 170 engages the cylindrical outer surface 438 of the roller 430.

As shown in FIG. 6, the middle pan 70 of the pan system 60 is coupled to the support bracket 246 between the side pans 72, 74. The pan body 182 of the middle pan 70 is positioned in the compartment 346 defined in the support bracket 246, and the roller 230 of the middle pan 70 is positioned in the inner roller support 366 of the support bracket 246. The cylindrical outer surface 232 of the roller 230 engages the top surface 374 of the lower flange 372 and the bottom surface 376 of the upper flange 370 of the support bracket 246. The other roller 228 of the middle pan 70 is similarly positioned in the inner roller support 368 of the support bracket 246. The cylindrical outer surface 232 of the roller 228 engages the top surface 374 of the lower flange 372 and the bottom surface 376 of the upper flange 370.

As described above, the support bracket 246 also includes a pair of rollers 390 positioned in the compartment 346. Each roller 390 has a cylindrical outer surface 392 that engages the bottom surface 216 of the corresponding lower flange 210, 212 of the middle pan 70. When the middle pan 70 is moved between the extended position and the retracted position, each roller 390 is rotated about its axis 396.

As shown in FIG. 6, each upper flange 370 of support bracket 246 has a tip 448 positioned in the compartment 346. When the middle pan 70 is coupled to the frame 62, the pan body 182 of the middle pan 70 is positioned between the tips 448 of the upper flange 370. The tips 448 of the upper flanges 370 confront the pan body 182 to locate the middle pan 70 in a predetermined lateral position within the frame 62. Additionally, the engagement between the rollers 122, 326 and the guide rails 310, 312, 170 locates the side pan 72 in a predetermined lateral position relative to the frame 62. The engagement between the rollers 124, 326 and the guide rails 310, 312, 172 similarly locates the side pan 74 in a predetermined lateral position relative to the frame 62.

As shown in FIG. 7, a gap 450 is defined between the front panel 76 of the side pan 72 and an edge 452 of the front panel 180 of the middle pan 70. Additionally, a gap 454 is defined between the front panel 76 of the side pan 74 and an edge 456 of the front panel 180 of the middle pan 70. Because the lateral positions of the crisper pan 64 within the frame 62 are fixed, the gaps 450, 454 have fixed predetermined sizes. As shown in FIG. 7, the gaps 450, 454 are substantially equal in size so that the side pans 72, 74 are equally spaced apart from the middle pan 70.

As described above, the crisper pans 64 are configured to extend and retract from the frame 62 to selectively permit user access to the storage chambers 66 of the crisper pans 64. To move the middle pan 70 from the retracted position to the extended position, a user grasps the handle 186 of the middle pan 70 and pulls forward. As the middle pan 70 is moved forward, the roller 228 is rotated about its axis 238 and is advanced along the inner roller support 368. Similarly, the roller 230 is rotated about its axis 238 and is advanced along the inner roller support 366. As the bottom surfaces 216 of the lower flanges 210, 212 of the middle pan 70 slide along the rollers 390 of the support bracket 246, the rollers 390 are rotated about their respective axes 396. When the middle pan 70 is in the extended position, the ribs 224 of the lower flanges 210, 212 engage the rollers 390, thereby inhibiting additional forward movement of the middle pan 70.

Referring now to FIGS. 8 and 9, the side pan 72 is shown in a retracted position such that user access to the storage chamber 66 is prevented. In the retracted position, the front panel 76 of the side pan 72 is positioned adjacent to the front wall 272 of the mounting plate 242. As shown in FIG. 8, the front panel 76 also engages the front end 274 of the main body 270. The pan body 78 of the side pan 72 is positioned below the cover panel 240.

As shown in FIG. 8, the roller 122 of the side pan 72 is located in the guide track 282 at the rear end 460 thereof. The cylindrical outer surface 128 of the roller 122 engages the upper surface 290 of the lower flange 284 and the lower surface 304 of the upper flange 286. As described above, the guide rails 310, 312 are positioned in the groove 136 of the roller 122 to direct the travel of the roller 122 when the side pan 72 is moved between the retracted position and the extended position.

As described above, the side pan 72 also has a lower flange 152, which is engaged with the roller 326 of the mounting plate 242. As shown in FIG. 8, the bottom surface 162 of the lower flange 152 engages the cylindrical outer surface 328 of the roller 326. As described above, a guide rail 170 extends downwardly from the lower flange 152. The guide rail 170 of the side pan 72 is received in the groove 334 of the roller 326 to direct the movement of the side pan 72 between the retracted position and the extended position. In the retracted position, the roller 334 is positioned in the notches 166, 174 defined in the lower flange 152 and the guide rail 170, respectively, to retain the side pan 72 in the retracted position.

Referring now to FIG. 9, the other side of the side pan 72 is shown with the side plate 354 of the support bracket 246. The roller 124 of the side pan 72 is positioned in the outer roller support 398 of the support bracket 246. The cylindrical outer surface 128 of the roller 124 engages the upper surface 406 of the lower flange 402 and the lower surface 408 of the upper flange 404. As described above, the side pan 72 also includes a guide rail 172, which is engaged with the roller 430 of the support bracket 246. As shown in FIG. 9, the bottom surface 176 of the guide rail 172 engages the cylindrical outer surface 438 of the roller 430. In the retracted position, the roller 430 is positioned in the notch 174 defined in the guide rail 172 of the side pan 72 to retain the side pan 72 in the retracted position.

To move the side pan 72 from the retracted position shown in FIGS. 8 and 9 to the extended position shown in FIG. 10, a user grasps the handle 82 of the side pan 72 and pulls in the direction indicated by arrow 462 in FIG. 8. As the side pan 72 is pulled forward, the lower flange 152 and the guide rail 170 slide along the roller 326, thereby causing the roller 326 to rotate about the axis 340 and to disengage from the notches 166, 174. Additionally, the roller 122 of the side pan 72 rotates about the axis 144 and advances forward along the track 282. On the opposite side of the pan 72, the guide rail 172 slides along the roller 430 of the support bracket 246, thereby causing the roller 430 to rotate about the axis 446 and disengaging the roller 430 from the notch 174. The roller 124 of the side pan 72 also rotates about its axis 144 and advances forward along the roller support 398. As the side pan 72 is moved between positions, the engagement between the rollers 122, 326 and the guide rails 310, 312, 170 limits the side-to-side motion of the pan 72.

When the side pan 72 is in extended position shown in FIG. 10, user access to the storage chamber 66 is permitted. The shoulder 148 extending from the upper flange 112 of the side pan 72 engages the tab 306 of the mounting plate 242. On the opposite side of the pan 72, the shoulder 148 extending from the other upper flange 114 of the side pan 72 also engages the tab 422 of the support bracket 246. The engagement between the shoulders 148 and the tabs 306, 422 inhibits additional forward movement of the side pan 72. As shown in FIG. 10, the shoulders 148 and the tabs 306, 422 prevent the roller 430 from engaging the middle surface section 298 of the lower flange 284.

It should be appreciated that the operation of the side pan 74 is similar to the operation of the side pan 72. When the side pan 74 is in the retracted position, the roller 334 of the mounting plate 244 is positioned in the notches 166, 174 defined in the lower flange 152 and the guide rail 172, respectively, to retain the side pan 74 in the retracted position. Additionally, the roller 430 is positioned in the notch 174 defined in the guide rail 170 of the side pan 74. When the side pan 74 is moved from the retracted position to the extended position, the engagement between the rollers 124, 326 and the guide rails 310, 312, 172 limits the side-to-side motion of the pan 74.

Referring now to FIG. 11, the side pan 72 is aligned with the cover panel 240 and the mounting plate 242 during installation of the side pan 72. To do so, the side pan 72 is angled downward so that the rear wall 96 clears the alignment tab 258. The side wall 90 is positioned in a gap 464 defined between the alignment tab 258 and the inner surface 280 of the mounting plate 242. As shown in FIG. 11, the gap 464 is sized such that the roller 122 of the side pan 72 is aligned with the guide rails 310, 312 of the mounting plate 242 and the guide rail 170 of the side pan 72 is aligned with the roller 326 of the mounting plate 242. When the side pan 72 is properly aligned with the frame 62, the side pan 72 may be moved backward to engage the rollers 122, 326 with the guide rails 310, 312, 170.

Similarly, during installation of the side pan 74, the side pan 74 is angled downward so that the rear wall 96 of the side pan 74 clears the alignment tab 260 of the frame 62. Similar to the side pan 72, the side wall 92 of the side pan 74 is positioned in the gap 464 defined between the alignment tab 260 and the inner surface 280 of the mounting plate 244. The roller 124 of the side pan 74 is aligned with the guide rails 310, 312 of the mounting plate 244 and the guide rail 172 of the side pan 74 is aligned with the roller 326 of the mounting plate 244. When the side pan 74 is properly aligned with the frame 62, the side pan 74 may be moved backward to engage the rollers 124, 326 with the guide rails 310, 312, 172.

It should be appreciated that the combination of rollers 120, 326, 430, the guide tracks 282, and the roller supports 398, 400 may be implemented in a pan system having only two pans. For example, the middle pan 70 may be omitted and the support bracket 246 replaced by a central plate including the roller supports 398, 400 and the rollers 430. Additionally, in other embodiments, the inner roller supports 366, 368 of the support bracket 246 may be replaced by guide tracks similar to the guide tracks 282 of the mounting plates 242, 244.
