ADJUSTABLE ORGANIZER SHELF SYSTEM

FIELD

The present disclosure relates generally to appliances and more particularly to adjustable organizer shelf systems for use in appliances, such as refrigerators.

BACKGROUND

Consumer appliances, such as refrigerator appliances, generally include a cabinet that defines one or more internal chambers. In the case of refrigerator appliances, a chilled chamber may be defined for receipt of food articles for storage. Consumer appliances can also include various storage components mounted within the one or more internal chambers. For example, refrigerator appliances can include various storage components within the chilled chamber, which are designed to facilitate storage of food items. Such storage components can include racks, bins, shelves, or drawers that receive food items and assist with organizing and arranging food items within the chilled chamber.

Some existing refrigerator appliances include one or more shelves for holding or supporting food items within the chilled chamber. Certain refrigerator appliances can include adjustable shelves that permit a user to change the positioning of the shelves. However, existing approaches to adjustable shelves present certain challenges and include limited adjustments or configurations that are not desirable for a particular consumer or application. For instance, existing adjustable shelves can include a single storage shelf divided into a fixed plate section and movable plate section, thus allowing adjustment of only a portion of the plates and leaving the fixed plate section to utilize and reduce storage capacity of the chilled chamber and reduce storage versatility in the chilled chamber.

Accordingly, an appliance with movable shelf features that address one or more of the challenges noted above or which provide additional shelf configurations would be useful and welcomed.

DETAILED DESCRIPTION

Reference now will be made in detail to embodiments of the disclosure, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the disclosure, not limitation of the disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the scope or spirit of the disclosure. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present disclosure covers such modifications and variations as come within the scope of the appended claims and their equivalents.

As used herein, terms of approximation, such as “approximately,” “substantially,” or “about,” refer to being within a ten percent margin of error.

Referring now to the figures, example aspects of the present disclosure will be discussed in greater detail.

FIG. 1 provides a perspective view of a refrigerator appliance 100 according to an exemplary embodiment of the present subject matter. Refrigerator appliance 100 defines a vertical direction V, a lateral direction L, and a transverse direction T. The vertical, lateral, and transverse directions V, L, and T are mutually perpendicular and form an orthogonal direction system.

Refrigerator appliance 100 includes a base cabinet or housing 110 that extends between a top portion 112 and a bottom portion 114 along the vertical direction V. Housing 110 defines a chilled chamber for receipt of food items for storage. In particular, housing 110 defines fresh food chamber 120 (shown in FIG. 2) positioned at or adjacent top portion 112 of housing 110 and a freezer chamber (not shown) arranged at or adjacent bottom portion 114 of housing 110. As such, refrigerator appliance 100 is generally referred to as a bottom mount refrigerator appliance or a bottom freezer refrigerator appliance. It is recognized, however, that the benefits of the present disclosure apply to other types and styles of refrigerator appliances such as, e.g., a top mount refrigerator appliance or a side-by-side style refrigerator appliance. Consequently, the description set forth herein is for illustrative purposes only and is not intended to be limiting in any aspect to any particular refrigerator chamber configuration.

Housing 110 also extends between a right side portion 106 and a left side portion 108, e.g., along the lateral direction L, forming a front portion 105. Housing 110 defines an opening 140 (shown in FIG. 2) for accessing fresh food chamber 120 (shown in FIG. 2) at or adjacent front portion 105 of housing 110. Housing 110 also includes a back wall 103 extending between a bottom portion 102 and a top portion 101, e.g., along the vertical direction V. Housing 110 also includes a left side portion 108 and a right side portion 106, both of which extend between a front portion 105 and a back wall 103, e.g., along the transverse direction T.

Refrigerator doors 124 are rotatably mounted or hinged to an edge of housing 110, e.g., at front portion 105 of housing 110, for selectively accessing chilled chamber 120. In addition, a freezer door 126 is arranged below refrigerator doors 124 for selectively accessing freezer chamber (not shown). Freezer door 126 is coupled to a freezer drawer (not shown) slidably mounted within freezer chamber (not shown). Refrigerator doors 124 are shown in an closed position and freezer door 126 are shown in a closed position in FIG. 1. When moved to an open position, refrigerator doors 124 permit access to chilled chamber 120 (shown in FIG. 2) through opening 140. Conversely, refrigerator doors 124 obstruct or limit access to chilled chamber 120 through opening 140 in the closed position in FIG. 1. Freezer door 126 operates similarly. Handles 128 can assist with operating refrigerator doors 124 and freezer door 126 between the open and closed positions.

FIG. 2 depicts a perspective view of a refrigerator appliance according to an exemplary embodiment of the present subject matter with doors 124 of the refrigerator appliance removed to reveal certain components within fresh food chamber 120 of the exemplary refrigerator appliance of FIG. 1.

Various storage components are mounted within chilled chamber 120 to facilitate storage of food items therein as will be understood by those skilled in the art. In particular, the storage components include bins (not shown), drawers 132, and shelves 134 that are mounted within chilled chamber 120. Bins (not shown), drawers 132, and shelves 134 are configured for receipt of food items (e.g., beverages and/or solid food items) and may assist with organizing such food items. As an example, drawers 132 can receive fresh food items (e.g., vegetables, fruits, and/or cheeses) and increase the useful life of such fresh food items. Refrigerator 100 can also include an adjustable organizer shelf assembly 300.

Although the illustrated embodiment shows two shelves 134 positioned adjacent each other along the lateral direction L and a shelf 134 positioned adjacent to adjustable organizer shelf assembly 300, that are positioned adjacent to shelves 134 along the vertical direction V, it should be appreciated that aspects of the present disclosure may be applied to other shelf assembly styles and configurations. For example, shelves 134 or adjustable organizer shelf assembly 300 could instead include a single storage shelf extending from the right side portion 106 to the left side portion 108 of refrigerator 100 along a lateral direction L. In addition, shelves 134 and additional shelves 134 may have any other suitable sizes or configurations. Moreover, it should be appreciated that adjustable organizer shelf assembly 300 as described herein may be utilized as one or more of shelves 134, and adjustable organizer shelf assembly 300 is designed such that shelves 134 may be interchangeable within the chilled chamber 120 and can be positioned at mounting points 142 affixed to a cabinet wall 110, or any other suitable mounting point or location within chilled chamber 120.

Referring now generally to FIGS. 3 and 4. FIG. 3 provides a perspective view of an adjustable organizer shelf assembly 300 according to an exemplary embodiment of the present subject matter. Adjustable organizer shelf assembly 300 is configured for use in any suitable refrigerator appliance.

First inner member 510 and second inner member 512 are separated in a vertical direction V to define a slot 514. Slot 514 extends along the transverse direction T between first inner member 510 and second inner member 512. Bottom member 364 and top member 504, face each other, e.g., along the vertical direction. Outside member 508 and first inner member 510, face each other, e.g., along the lateral direction. Bottom member 364, outside member 508, top member 504, first inner member 510 and second inner member 512 define a channel 516. Channel 516 extends in a transverse direction T along top surface 344 from the proximate end 354 of movable shelf toward distal end 352 of movable shelf.

In the embodiment depicted in FIG. 5, channel 516 is a “C” shape, however, channel 516 can be any other shape configured capable of accept roller, such as roller 516. Roller 516 can be any suitable wheel, cylinder or other shape that is capable of rolling or moving within channel 516 along transverse direction T along. Roller 516 is attached to lower roller hinge 518.

Each hinge side support 520 includes a pin hole (not shown) configured to allow insertion of a pin 524, screw, rivet or other suitable devices through each pin hole (not shown) and through first lifting arm 356. Pin 524 mechanically attaches first lifting arm 356 and lower roller hinge 350 in such a manner as to allow first lifting arm 356 to pivot or rotate about pin 524.

Each upper guide 330 includes a bottom member 502. Upper guide 330 affixed to right-side bracket 302 as depicted in FIG. 5. However, it would be appreciated that upper guide 330 can also be affixed to left-side bracket 304 and has the same or similar features as described with respect upper guide 330 depicted in FIG. 5. Bottom member 502 extends in a transverse direction T from the proximate end 306 of bracket 302 toward the distal end 308 of bracket 302. Each upper guide 330 includes an outside member 530 which extends upward, in a vertical direction V, from bottom member 502 and extends in a transverse direction T along bracket 302 from the proximate end 306 of bracket toward distal end 308 of bracket. Top member 532 of upper guide 330 extends from outside member 530 in a lateral direction L inward toward center of fixed shelf 320. Each upper guide 330 further includes a first inner member 534 and second inner member 536. First inner member 534 extends downward, in a vertical direction V, from top member 532. Second inner member 534 extends upward, in a vertical direction V, from bottom member 502. First inner member 534 and second inner member 536 are separated in a vertical direction V to define a slot 538. Slot 538 extends along the transverse direction T between first inner member 534 and second inner member 536. Bottom member 502 and top member 532 face each other, e.g., along the vertical direction V. Outside member 530 faces first inner member 534 and second inner member 536, e.g., along the lateral direction L. Upper guide 330 includes a guide surface 540 which extends between second inner member 536 and outside member 530 in the lateral direction L and the transverse direction T.

Bottom member 502, outside member 530, guide surface 540, and second inner member 512 define a cavity 542. In the exemplary embodiment depicted in FIGS. 5 and 6, cavity 542 is a square or rectangular shape, however, cavity 542 can be any other shape configured to accept stop bar 602 (shown in FIGS. 6 and 7). Guide surface 540, outside member 530, top member 532 and first inner member 534 define a channel 544. Channel 544 extends in a transverse direction T along top surface 344 from the proximate end 354 of movable shelf toward distal end 352 of movable shelf.

In the embodiment depicted in FIGS. 5 and 6, channel 544 is an inverted “L” shape, however, channel 544 can be any other shape configured capable of accepting a roller, such as roller 800. Roller 800 is depicted in further detail in FIGS. 8 and 9. Roller 800 is configured to roll or moving on guide service 540 and within, at least a portion of channel 544 along transverse direction T. Roller 800 is attached to upper roller hinge 604. Upper roller hinge 604 includes two side supports 606, extending downward in the vertical direction V away from fixed shelf plate 322, and a top support 608 extending between the side supports 606 to form an inverted “U” shape facing downward in vertical direction V.

Upper roller hinge 604 is configured to accept a portion of second lifting arm 358 between hinge side supports 606 and secure second lifting arm 358 to upper roller hinge 604. Each hinge side support 606 includes a pin hole (not shown) configured to allow insertion of a pin 610 through each pin hole (not shown) and through second lifting arm 358. Pin 610 mechanically attaches second lifting arm 358 and upper roller hinge 604 in such a manner as to allow second lifting arm 358 to pivot or rotate about pin 610.

Upper guide 330 of adjustable organizer shelf 300 includes stop bar 602. Stop bar 602 includes a plurality of nodules 612. Guide surface 540 includes a plurality of passages 614 corresponding to each of the plurality of nodules 612. Passages 614 extend between cavity 542 and channel 544 in a vertical direction V. Each of the plurality of nodules 612 can pass through passages 614 from cavity 542, such that nodules 612 protrude upward, in the vertical direction V, into channel 544 through passages 614 or retract downward, in the vertical direction V, into cavity 542.

FIG. 7 depicts a partial section view of upper guide 330 of the adjustable organizer shelf assembly 300 of FIG. 3 taken along the A-A section line of FIG. 6. Stop bar 602 is pivotally attached or joined to upper guide 330 at hinge point 620 which is disposed within cavity 542. Hinge point 620 can be a pin, screw, rivet or other suitable device which facilitates pivotable attachment of stop bar 602 to upper guide 330. Each nodule 612 includes a striking surface 616 and holding surface 618. A handle 720 is attached to stop bar 602. Handle 720 extends outside of cavity 542 and can be engaged (e.g., depressed or pushed in a downward vertical direction V) by a user. Stop bar 602 includes a stop nodule 724, which is one of the plurality of nodules 612 situated closet to hinge point 620. Stop bar 602 includes a storage nodule 726, which is one of the plurality of nodules 612 situated closet to handle 720. Upper guide 330 can also include spring 722 which is situated between bottom member 502 and stop bar 602. In some embodiments spring 722 can be located at an end of stop bar 602 closest to handle 720. Spring 722 exerts force against stop bar 602 upward in a vertical direction V such that nodules 612 protrude through passages 614 into channel 544. When a user engages handle 720 (e.g, by pressing down on handle 720), stop bar 602 rotates at hinge point 620 and compresses spring 722 such that each of the plurality of nodules 612, except stop nodule 724, retract into cavity 542. In this way roller 800 can move along guide surface 540 between stop nodule 724 and storage nodule 726. Movable shelf 340 can be in a fully extended position when holding surface 904 (shown in FIG. 9) of roller 800 is in contact with holding surface 618 of stop nodule 724 (as shown in FIG. 7). Similarly, movable shelf 340 can be in a fully retracted position when holding surface 904 (shown in FIG. 9) of roller 800 is in contact with holding surface 618 of storage nodule 726.

Referring now generally to FIGS. 8 and 9. FIG. 8 depicts a perspective view of roller 800 of the upper guide 300 of adjustable organizer shelf assembly 300 of FIG. 3. Roller 800 includes circumferential edges 802. Edges 802 contact and roll upon guide surface 540 of upper guide 330. Roller 800 includes a plurality of nodule reception cavities 804, situated between the circumferential edges 802 and formed by striking surface 902 and holding surface 904 (shown in FIG. 9). Nodule reception cavities 804 are configured such that nodule 612, or at least a portion thereof, can be accepted in each of the nodule reception cavities 804 (shown in FIG. 7).

FIG. 9 depicts a partial section view of a roller 800 of the upper guide 330 of the adjustable organizer shelf assembly 300 of FIG. 3 taken along the B-B section line of FIG. 8. Each nodule reception cavity 804 includes a striking surface 902 and holding surface 904 (shown in FIG. 9).

Referring again generally to FIGS. 5, 6 and 7, when holding surface 904 of roller 800 contacts holding surface 618 of nodule, roller 800 is prevented from moving in a transverse direction T toward the distal end 308 of brackets 302 and 304. In this way, upper guide 330 prevents second lifting arm 358 and first lifting arm 356 from rotating or pivoting at pivot joint 360. For example, FIG. 7 depicts holding surface 618 of stop nodule 724 in contact with holding surface 904 of roller 800 thereby preventing roller 800 from moving past stop nodule 724 in a transverse direction T toward distal end 308 of bracket 302.

As discussed above, movable shelf 340 is movable between a fully extended position (shown in FIG. 3) and a fully retracted position (shown in FIG. 4). A user can move movable shelf 340 up (e.g., toward a fully retracted position) by placing upward force on shelf 340 in a vertical direction V. Such upward force from the user will cause second lifting arm 358 to push roller 800 within upper guide 330 in a transverse direction T toward the proximate end of bracket 302. When roller 800 is moving in a transverse direction toward proximate end 306 of bracket 302, striking surface 902 of roller 800 will contact striking surface 616 of stop bar nodules 612. Such contact between striking surface 902 and striking surface 616 push stop bar nodules 612 in a downward vertical direction V through passages 614 and into cavity 542, thereby allowing roller 800 to move past nodule 612 in a transverse direction T. Once roller 800 moves past passage 614 in a transverse direction T toward proximate end 306 of bracket 302, spring 722 exerts a vertical force against stop bar 602 causing nodules 612 to extend back through passages 614 into channel 544.

User can select the vertical position of movable shelf 340 relative to fixed shelf 320 by selectively engaging a nodule reception cavity 804 of roller 800 with the nodule 612 (including stop nodule 724 and storage nodule 726) corresponding to the location or vertical position of movable shelf 340 which is desired by user.

User can move movable shelf 340 from the fully retracted position by pressing or applying downward force to stop bar handle 720, thereby compressing spring 722 and causing all nodules 612, except stop bar nodule 724, to retract into cavity 542. This allows roller 800 to move or roll along guide surface 540 in a transverse direction T toward distal end 308 of bracket 302.

Referring again generally to FIGS. 10 and 11. FIG. 10 depicts a partial perspective view of another exemplary embodiment of an upper guide 920 of the present disclosure, which can be utilized with adjustable organizer shelf assembly 300, such as the adjustable organizer shelf assembly of FIG. 3, in lieu of the exemplary upper guide 330 described hereinabove. FIG. 11 depicts a side section view of the upper guide 920 of FIG. 10 taken along the C-C section line of FIG. 10.

FIG. 10 depicts a partial perspective view of an exemplary embodiment of an upper guide 920 of the present disclosure with can be utilized with an adjustable organizer shelf assembly, such as adjustable organizer shelf 300 of FIG. 2. Upper guide 920 includes a bottom member 502. In FIG. 10 upper guide 920 is affixed to right-side bracket 302. However, it should be appreciated that an upper guide 920 can also be affixed to left-side bracket 304 and have the same features described with respect to FIGS. 10 and 11. Bottom member 502 extends in a transverse direction T from the proximate end 306 of bracket 302 toward the distal end 308 of bracket 302. Each upper guide 920 includes an outside member 530 which extends upward, in a vertical direction V, from bottom member 502 and extends in a transverse direction T along bracket 302 from the proximate end 306 of bracket toward distal end 308 of bracket. Top member 532 of guide 920 extends from outside member 530 in a lateral direction L inward toward center of fixed shelf 320. Each guide 920 further includes a first inner member 534 and second inner member 536. First inner member 534 extends downward, in a vertical direction V, from top member 532. Second inner member 534 extends upward, in a vertical direction V, from bottom member 502. First inner member 534 and second inner member 536 are separated in a vertical direction V to define a slot 538. Slot 538 extends along the transverse direction T between first inner member 534 and second inner member 536. Bottom member 502 and top member 532 face each other, e.g., along the vertical direction V. Outside member 530 faces first inner member 534 and second inner member 536, e.g., along the lateral direction L. Guide 920 includes a guide surface 922 which extends between second inner member 536 and outside member 530 in the lateral direction L and the transverse direction T.

Bottom member 502, outside member 530, guide surface 540, and second inner member 512 define a cavity 542. In the embodiment depicted in FIGS. 10 and 11, cavity 542 is a square or rectangular shape, however, cavity 542 can be any other shape. Guide surface 922, outside member 530, top member 532 and first inner member 534 define a channel 544. Channel 544 extends in a transverse direction T along top surface 344 from the proximate end 306 of bracket 302 toward distal end 308 of bracket 302.

In the embodiment depicted in FIGS. 10 and 11, channel 544 is an inverted “L” shape, however, channel 544 can be any other shape configured capable of accept roller, such as roller 800. Roller 800 is depicted in further detail in FIGS. 8 and 9, however, it should be appreciated that other configurations of roller 800 can be utilized with upper guide 920, specifically a roller 800 excluding nodule reception cavities 804, so long as roller 800 is configured to roll or moving on guide service 922 and within, at least a portion of channel 544 along transverse direction T. Roller 800 is attached to upper roller hinge 604. Upper roller hinge 604 includes two side supports 606, extending downward in the vertical direction V away from fixed shelf plate 322, and a top support 608 extending between the side supports 606 to form an inverted “U” shape facing downward in vertical direction V.

Upper guide 920 includes a plurality of depression stops 924. Depression stops 924 can be a series of depressions in guide surface 922 that extend in a downward direction V toward cavity 542 from channel 544. Alternatively, depression stops 924 can be passages, gaps or holes in guide surface 922.

Depression stops 924 are sized and configured based, at least in part, on the size of roller 800. More specifically, roller has an outside diameter 926 (shown in FIG. 9). The length 928 (in the transverse direction T) of depression stops 924 is based upon outside diameter 926. More precisely, length 928 of depression stops 924 is between about 20% and about 40% of outside diameter 926 of roller 800. In this way only a portion of roller 800 can enter or rest in depression stop 924, thereby allowing a portion of roller 800 to pass into cavity 542 (as shown in FIG. 11) and thereby, prevent roller from rolling or moving along guide surface 922 within channel 544.

Roller 800 can move or roll along guide surface 922 between the plurality of depression stops 924. User can select the vertical position of movable shelf 340 relative to fixed shelf 320 by selectively engaging roller 800 with one of the plurality of depression stops 924 corresponding to the user desired location or vertical position of movable shelf 340. User can move movable shelf 340 from the fully retracted position toward the fully extend position by pressing or applying downward force to movable shelf 340, thereby causing roller 800 to move out of the depression stop 924 in which roller 800 is situated, thus forcing the entirety of roller 800 into channel 544 such that roller can move or roll along guide surface 922 in a transverse direction T toward distal end 308 of bracket 302 until roller 800 reaches another of the plurality of depression stops 924 which correspond with the user's desired location or vertical position of movable shelf 340.

Similarly user can move movable shelf 340 from the fully extended position toward the fully retracted position by pressing or applying an upward force to movable shelf 340, thereby causing roller 800 to move out of the depression stop 924 in which roller 800 is situated, thus forcing the entirety of roller 800 into channel 544 such that roller can move or roll along guide surface 922 in a transverse direction T toward proximate end 306 of bracket 302 until roller 800 reaches another of the plurality of depression stops 924 which corresponds to the user's desired location or vertical position of movable shelf 340.

Referring now generally to FIGS. 12, 13, 14, 15 and 16. FIG. 12 depicts a partial perspective view of an adjustable organizer shelf assembly 300, including a cable stabilizer assembly 950 according to an exemplary embodiment of the present disclosure. FIG. 13 depicts a partial perspective view of the cable stabilizer assembly 950 of FIG. 12 without the inclusion of the fixed plate 322 of the fixed shelf 320, in order to provide an unobstructed view of a portion of the cable stabilizer assembly 950, and portions of adjustable organizer shelf assembly 300 according to an exemplary embodiment of the present disclosure.

Cable stabilizer assembly 950 is operably connected to upper guide 330 attached to right bracket 302 and upper guide 330 attached to left bracket 304 such that rollers 800 of both upper guides 330 move in substantially the same positions along a plane formed in the lateral direction L as rollers move in a transverse direction T within channels 544 of upper guides 330. In this manner, cable stabilizer assembly 950 avoids adjuster organizer shelf assembly 300 (specifically first lifting arm 356 and second lifting arm 358) from racking or twisting when movable shelf 340 is moved between the fully extended position and the fully retracted position.

Cable stabilizer assembly 950 includes a pair of cables 952. Cables 952 can be made from metal, plastic, nylon or another similar material. Cable stabilizer assembly 950 includes a plurality of cable clips 956 which include a slot configured to accept and secure cables 952. As depicted in FIG. 15, cable clips 956 are affixed to rear upper hinges 350 and upper guides 330 by a known fastening method, e.g., welding, adhesive, screws and/or bolts. Alternatively, cable clips 956 can be integrally formed with rear upper hinges 350 and upper guides 330. Cable stabilizer assembly includes a cable pulley assembly 954.

As detailed in FIG. 14, cable pulley assembly 954 includes a pulley bracket 958 and a pair of pulley wheels 960. Cable pulley assembly 954 is affixed or mounted to upper roller hinge 604. Cable pulley assembly 954 is affixed or mounted to upper roller hinge 604 by a known fastening method, e.g., welding, adhesive, screws and/or bolts. Alternatively, pulley bracket 958 of cable pulley assembly 954 can be integrally formed with upper roller hinge 604. Cables 952 ride along pulley wheels 960 when movable shelf 340 is moved between the fully extend position and fully retracted position.

FIG. 16 depicts a schematic view of a configuration of the cables 952 of the cable stabilizer assembly of FIGS. 12 through 15. As shown in FIG. 16, a first of the pair of cables 952 (i.e., first cable 952A) extends from cable clip 956 affixed to rear upper hinge 350 attached to bracket 302, to cable pulley assembly 954 affixed to upper roller hinge 604 attached to bracket 302, to cable pulley assembly 954 affixed to upper roller hinge 604 attached to bracket 304 and lastly to cable clip 956 affixed to guide 330 attached to bracket 304. Conversely the second of the pair of cables 952 (i.e., second cable 952B) extends from cable clip 956 affixed to rear upper hinge 350 located attached to bracket 304, to cable pulley assembly 954 affixed to upper roller hinge 604 attached to bracket 304, to cable pulley assembly 954 affixed to upper roller hinge 604 attached to bracket 302 and lastly to cable clip 956 affixed to guide 330 attached to bracket 302.

Referring now generally to FIGS. 17 and 18. FIG. 17 depicts a partial perspective view of an adjustable organizer shelf assembly 300 with a bar stabilizer assembly 970 according to an exemplary embodiment of the present disclosure. FIG. 18 depicts a partially exploded perspective view of a portion of the bar stabilizer assembly 970 of FIG. 17. Bar stabilizer assembly 970 includes a bar 972 which extends in a lateral direction between second lifting arm 358 that is movably attached to the upper guide 300 which attached to bracket 304 and second lifting arm 358 that is movably attached to the upper guide 300 which is attached to bracket 302. Bar 972 can be metal, plastic or another suitable rigid material. Bar 972 is attached to each second lifting arm 358 at a mounting hole 976 located near upper roller hinge 604, so that bar 972 does not interfere with storage of food items on movable shelf 340. Bar 972 can be attached to each of the second lifting arm 358 by a pin, screws and/or bolts. Bar 972 can include a bushing 974 which is positioned around stabilizer bar and between second lifting arm 358 to reduce movement, binding or rattling of stabilizer bar 972 when it is affixed to second lifting arms 358.

Bar stabilizer assembly 970 is operably connected to second lifting arm 358 which is movably attached to upper guide 330 that is attached to bracket 304 and second lifting arm 358 which is movably attached to upper guide 330 that is attached to bracket 302 such that rollers 800 of both guides 330 move in substantially the same positions along a plane formed in the lateral direction L as rollers 800 move in a transverse direction T within channels 544 of guides 330. In this manner, bar stabilizer assembly 970 prevents adjustable organizer shelf assembly 300, and specifically second lifting arms 358, from racking or twisting when movable shelf 340 is moved between the fully extended position and the fully retracted position.

Referring now generally to FIGS. 19, 20 and 21. FIG. 19 depicts a partial perspective view of another example embodiment of a bar stabilizer assembly 970, with alternate attachment components depicted for affixing stabilizer bar 972 to each of the two second lifting arms 358 according to another exemplary embodiment of the present disclosure. FIG. 20 depicts a partially exploded perspective view of a portion of the bar stabilizer assembly 970 of FIG. 19. FIG. 21 depicts a partial section view of the bar stabilizer assembly 970 of FIG. 19 taken along the C-C section line of FIG. 19.

Bar stabilizer assembly 970 includes a bar 972 which extends in a lateral direction between the second lifting arm 358 which is movably attached to the guide 330 that is attached to bracket 304 and the second lifting arm 358 which is movably attached to the guide 330 that is attached to bracket 302 (as shown in FIG. 17). Bar 972 can be metal, plastic or another suitable rigid material. Bar 972 is attached to each second lifting arm 358 at a location near upper roller hinge 604, such that bar 972 does not interfere with storage of food items on movable shelf 340. Bar stabilizer assembly 970 can include a first mounting nodule 978 affixed to one of the second lifting arms 358 and a second mounting nodule 979. First mounting nodule 978 and second mounting nodule 979 can be a protrusion, such as the cylindrical protrusion shown in FIGS. 19 and 20, which extends away from each of the two second lifting arms 358 in a lateral direction L inward toward center of fixed shelf 320. First mounting nodule 978 forms a cavity or void 980. Second mounting nodule 979 forms a cavity or void 980. Mounting nodules 978 and 979 can be made of any suitable material, such as metal or plastic. Mounting nodules 978 and 979 can be attached to each of the respective second lifting arms 358 by welding, adhesive, or other known methods of attachment. Alternatively, mounting nodules 978 and 979 can be integrally formed as a single piece with each of the second lifting arms 358.

Bar stabilizer assembly 970 includes a mounting coupler 982 and a clip 984 situated at a first end 971 of bar 972. Mounting coupler 982 includes a coupler protrusion 986. Coupler protrusion 986 and mounting nodule void 980, of first mounting nodule 978, have corresponding shapes and dimensions such that coupler protrusion 986 may be inserted partially or completely within mounting nodule void 980 of first mounting nodule 978. Mounting coupler 982 forms a cavity or void 988. Stabilizer bar 972 includes a first mounting protrusion 990 at first end 971 of stabilizer bar 972 and a second mounting protrusion 991 at a second end 973 of stabilizer bar 972. First mounting protrusion 990 and second mounting protrusion 991 extend from stabilizer bar 972 in a lateral direction L toward one of each of the mounting nodules 978 and 979. First mounting protrusion 990 and mounting coupler void 988 have corresponding shapes and dimensions such that first mounting protrusion 990 may move in a lateral direction within coupler void 988. First mounting protrusion 990 can be inserted partially or disposed entirely within mounting collar void 988. Second mounting protrusion 991 and mounting nodule void 980 of second mounting nodule 979 have corresponding shapes and dimensions such second mounting protrusion 991 may be inserted partially or completely within mounting nodule void 980 of second mounting nodule 979.

Mounting coupler 982 includes a clip passage 992. Clip 984 includes a locking member 994. Clip can be attached around coupler 982 such that locking member 994 passes through clip passage 992 and extends into the mounting coupler void 988. When locking member 994 extends into mounting coupler void 988, locking member 994 to prevents first mounting protrusion 990 from moving in a lateral direction L within coupler void 988 toward coupler protrusion 986. In this manner first mounting protrusion 990 cannot be disposed entirely within mounting coupler void 988. Locking member 994 prevents first mounting protrusion 990 from moving into collar void 988 past clip cavity 992 in a lateral direction L toward collar protrusion 986.

Second mounting protrusion 991 can be inserted into nodule void 980 of the second mounting nodule 979 which is affixed to one of the second lifting arms 358 as shown in FIG. 20. When second mounting protrusion 991 at the second end of bar 973 is inserted within nodule void 980 of second mounting nodule 979, and first mounting protrusion 990 is completed disposed within collar void 988, no portion of the coupler mounting protrusion 986 is disposed within the mounting nodule void 980 of first mounting nodule 978. In this way the bar 972 can be positioned between each of the two second lifting arms 358 without bending. Mounting coupler 982 can be then be moved in a lateral direction L so that the coupler protrusion 986 is inserted within the nodule void 980 of the first mounting nodule 978 and the path between clip passage 992 and mounting coupler void 988 is not obstructed by any portion of first mounting protrusion 990. When the clip 984 is attached to the mounting coupler 982 so that at least a portion of the locking member 994 is disposed within the coupler void 988, locking member 994 prevents bar 972 from moving in a lateral direction such that that at least a portion of mounting coupler protrusion 986 remains at least partially inserted or partially disposed within the nodule void 980 of the first mounting nodule 978, at least a portion of the first mounting protrusion 990 remains inserted or partially disposed within the mounting collar void 988 and at least a portion of second mounting protrusion 991 remains at least partially inserted or partially disposed within the nodule void 980 of the second mounting nodule 979.

In this way bar stabilizer assembly 970 depicted in FIGS. 19, 20 and 21 is operably connected to second lifting arm 358 which is movably attached to upper guide 330 that is attached to bracket 304 and second lifting arm 358 which is movably attached to upper guide 330 that is attached to bracket 302 such that rollers 800 of both guides 330 move in substantially the same positions along a plane formed in the lateral direction L as rollers 800 move in a transverse direction T within channels 544 of guides 330. In this manner, bar stabilizer assembly 970 prevents adjustable organizer shelf assembly 300, and specifically second lifting arms 358, from racking or twisting when movable shelf 340 is moved between the fully extended position and the fully retracted position.

It should be appreciated that the stabilizer assemblies described are only exemplary and that other stabilizer mechanisms may be used according to alternative embodiments.
