FIELD OF THE INVENTION
The present invention generally relates to refrigerators. More particularly, the present invention relates to a refrigerator storage bin, including a flip-top cover. In one particular form, the present invention relates to a refrigerator storage bin including a flip-top cover that articulates from a closed position to an open position in response to translation of the storage bin from a retracted position to an extended position.
BACKGROUND OF THE INVENTION
Vehicles including but not limited to recreational vehicles (“RVs”), tractor trailers, airplanes, boats, trains, and the like often incorporate refrigerators for the comfort and convenience of the occupants. Space available for refrigerators on such vehicles is limited and a significant design emphasis has been placed upon maximizing refrigerator storage volume.
Refrigerators, including those designed specifically for vehicles, conventionally incorporate bins for the storage of items. For example, such storage bins are commonly used to retain produce. Within the bin, produce and the like can be randomly placed and stacked such that the storage volume is not entirely limited by the square area of a support surface (e.g., shelf or cabinet bottom). Explaining further, the walls of the storage bin cooperate to effectively and efficiently retain produce and other goods within the refrigerator. Many known refrigerator storage bins are equipped with covers. Such conventional covers retain moisture within the bin to preserve freshness, otherwise protect the bin contents, and contribute to an organized appearance of an interior of the refrigerator.
Accordingly, it remains a need in the pertinent art to provide a refrigerator storage bin that overcomes the limitations associated with the prior known arrangements, including but not limited to those disadvantages discussed above.
SUMMARY OF THE INVENTION
It is a general object of the present invention to provide a refrigerator storage bin including a cover that articulates from a closed position to an open position in response to translation of the storage bin from a retracted position to an extended position.
It is a related object of the present invention to provide a storage bin for a refrigerator having a cover that is pivotally connected to a cabinet of the refrigerator.
In one particular form, the present invention provides a refrigerator storage bin including a main body portion and a cover. The main body portion defines a bin storage area. The cover selectively provides access to the bin storage area. The cover is pivotally attached to a sidewal of a cabinet of the refrigerator for rotation about a pivot axis between an opened position and a closed position. The cover and main body portion include cooperating surfaces that articulate to cover from the closed position to the open position in response to translation of the main body portion from a first position to a second position.
Additional advantages and features of the present invention will become apparent from the following description and appended claims, taken in conjunction with the accompanying drawings.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The following description of the preferred embodiment of the present invention is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
With reference to the drawings, a refrigerator storage bin constructed in accordance with the teachings of a preferred embodiment of the present invention is illustrated and generally identified at reference character 10. The storage bin 10 is shown throughout the drawings associated with a cabinet 12 of a refrigerator. It will be understood by those skilled in the art that the particular cabinet illustrated is exemplary in nature and that the subject invention is not limited thereto.
The storage bin 10 is illustrated to generally include a main body portion 14, a cover 16, the main body portion 14 defines a bin storage area 18. The main body portion 14 is generally rectangular in shape and includes a forward side 20 having a handle 22.
The main body portion 14 is translatable between laterally opposed sidewalls 23 of the cabinet 12 between a first or retracted position and a second or extended position. In the retracted position, shown for example in FIGS. 1 and 5, the main body portion 14 is disposed completely within the cabinet 12. In the extended position shown in FIGS. 2 and 7, the main body portion 14 partially extends from the cabinet 12. An intermediate position is illustrated in FIG. 6.
The cover 16 is operative for selectively providing access to the bin storage area 18. The cover 16 is pivotally attached to the opposing sidewalls of the cabinet 12 with a pair of pivot pins 24. Explaining further, both of the lateral sides of the cover 16 include a downwardly extending leg 26 (shown perhaps most clearly in the cross-sectional view of FIG. 4). The downwardly extending legs 26 are spaced apart from an adjacent main portion of the cover 16 so as to define an opening 28 therebetween.
At a point of the cover 16 whereat the downwardly extending leg 26 engages the remainder of the cover 16, a closed end 30 of the opening 28 is defined which is generally circular. The diameter of the end 30 is substantially equal to the diameter of the associated pivot pin 24. The opening 28 tapers slightly leading to the end 30 such that a portion of the opening 28 immediately adjacent the end 30 has a width slightly less than the pin diameter. In this manner, the opening 28 can be easily located by the pivot pin 24 during installation of the cover and the pivot pin 24 is received in a snap-fit relationship within the opening 30. In this manner, the cover 16 is pivotally retained on the pivot pin 24 independent of the main body portion 14.
The cover 16 and the main body portion 14 include cooperating surfaces 34 and 36, respectively (see FIG. 6). The cooperating surfaces 34 and 36 serve to articulate the cover 16 from the closed position to the open position in response to translation of the main body portion 14 from the retracted position to the extended position. The cooperating surface 34 of the cover 16 is defined by a lower and rear side of the downwardly extending legs 26. The cooperating surface 36 of the main body portion 14 includes an upper edge of the opposed sidewalls 38 (see FIG. 3) of the main body portion 14. The upper ends include an intermediate curvilinear segment 40 (see FIG. 5) which transitions between a first generally horizontal portion 42 and a higher, second generally horizontal portion 44.
When the main body portion 14 of the storage bin 10 is in its retracted position (as shown in FIG. 5), the main portion of the cover 16 rests on the horizontal portion 42 of the upper end of the sidewalls and the cover 16 prevents access to the storage bin 18. As the main body portion 14 is manually translated from the retracted position toward the extended position, the downwardly extending legs 26 of the cover 16 engage the curvilinear portion 40 and thereby cause the cover 16 to articulate about the pivot axis defined by the pivot pins 24 in a clockwise direction (as shown in FIG. 6). Further translation of the main body portion 14 causes corresponding clockwise rotation of the cover 16 due to the increased height of the portion of the curvilinear segment 40 that engages the downwardly extending legs 26. As the downwardly extending legs 26 reach the upper horizontal portions 44 of the upper ends of the sidewalls 38, the cover 16 is articulated to its fully open position (shown in FIG. 7). At this point, the main body portion 14 can be further translated in the direction of arrow A (see FIG. 7) and thereby be removed completely from the cabinet 12.
In the exemplary embodiment illustrated, both the main body portion 14 and the cover 16 are constructed of a substantially rigid plastic. The cover 16 is preferably translucent. Alternatively, other known materials may be incorporated.
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
