Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention pertains to the art of refrigerators and, more particularly, to a combination shelf and serving tray assembly for use in a refrigerator.




2. Discussion of the Prior Art




A typical household refrigerator is provided with numerous vertically spaced shelves for use in supporting food items stored in the refrigerator. In the past, various proposals have also been made to enhance the versatility of refrigerator shelving arrangements. For example, proposals have been made to support shelves at various, selected heights within a refrigerator cabinet in order to accommodate different size food items. In order to enhance access to food items placed in a back portion of a shelf, it has also been proposed in the art to slidably mount refrigerator shelves for movement between extended and retracted positions. It has also been proposed to provide a refrigerator with a planar shelf member that can be selectively supported upon a frame within a compartment of the refrigerator so as to define a shelf, while also enabling the platform to be removed from the refrigerator and used as a tray.




It is known to combine many of these features into a single overall shelving arrangement. For example, U.S. Pat. No. 2,032,235 discloses a refrigerator incorporating a shelf platform which is adapted to be selectively removed from the cabinet of a refrigerator and used as a tray. More specifically, the tray is adapted to be supported upon a frame including a pair of spaced support members for sliding movement into and out of the refrigerator cabinet. In addition, the tray can be completely removed from the cabinet in order to carry away food products supported thereon.




Although certain advancements have been made in this art to increase the versatility of known refrigerator shelving arrangements, there still exists a need for an improved shelf and serving tray assembly for a refrigerator. More specifically, there exists a need in the art for an assembly which can be manufactured in an economical manner and incorporates a simple and efficient support arrangement for the tray whether used inside or outside of the refrigerator.




SUMMARY OF THE INVENTION




The present invention pertains to a combination shelf and serving tray assembly for use in a refrigerator including a shelving platform removably supported upon a frame mounted within a compartment of the refrigerator. More particularly, the platform is slidably mounted upon the frame for movement between extended and retracted positions relative to the refrigerator compartment and is designed to be completely removed from the compartment for use as a serving tray. In accordance with the most preferred embodiment of the invention, an underside of the tray is provided with various spaced projections in the form of legs that are preferably provided with elastomeric tips. The frame includes fore-to-aft extending and laterally spaced rails formed with respective elongated slots. When the platform is positioned within the refrigerator compartment, each of the legs extends into a respective one of the slots in order to guide the platform between the extended and retracted positions. The length of the slots and the spacing between the legs defines the extent to which the platform can be slid relative to the refrigerator compartment. When the platform is removed from the compartment and used as a serving tray, the legs support the tray through the elastomeric tips. The platform preferably includes an annular, upstanding peripheral edge which functions to advantageously contain any minor spills.




With this construction, the combination shelf and serving tray assembly of the invention represents a versatile arrangement for both storing food items in a refrigerator compartment and readily removing the food items simultaneously from the compartment. The legs of the shelving platform provide both support and guiding functions in a convenient and economical manner. In any event, additional objects, features and advantages of the present invention will become more readily apparent from the following detailed description of a preferred embodiment thereof when taken in conjunction with the drawings wherein like reference numerals refer to corresponding parts in the several views.

for exemplary purposes. Therefore, although assembly


25


of the present invention is shown for use in a side-by-side refrigerator cabinet


2


, it should be readily understood that assembly


25


could be utilized in various other types of cabinets, including top mount style refrigerators, without departing from the spirit of the invention.




In general, shelf and serving tray assembly


25


of the invention includes a shelf support frame


27


incorporating a pair of laterally spaced and fore-to-aft extending support rails


30


and


31


which are interconnected by front and rear cross braces


34


and


35


. For purposes of the invention, shelf support frame


27


can be mounted within fresh food compartment


6


in various ways. As shown, support rails


30


and


31


are provided with rearwardly projecting connectors


38


and


39


which are adapted to be attached to respective brackets


42


and


43


mounted to rear wall


12


of compartment


6


. In this manner, shelf support frame


27

6


. More specifically, brackets


42


and


43


are formed with various vertically spaced mounting slots


45


for use in selectively positioning shelf support frame


27


at a desired height within fresh food compartment


6


. The particular mounting of shelf support frame


27


is not considered part of the present invention and is merely presented herein for the sake of completeness.




Once shelf support frame


27


is mounted within fresh food compartment


6


, an upper surface


49


of each of support rails


30


and


31


generally extends in a horizontal plane. Furthermore, as clearly shown in these figures, the upper surface


49


of each support rail


30


,


31


is provided with at least one vertically extending opening


52


. More specifically, in accordance with the most preferred embodiment of the invention shown herein, opening


52


provided in the upper surface


49


of each support rail


30


,

to short of a rear end portion


56


of a respective one of the support rails


30


,


31


.




The shelf and serving tray assembly


25


of the present invention also includes a tray which is generally indicated at


60


. As will be detailed more fully below, tray


60


can be selectively supported upon shelf support frame


27


or can be completely removed from fresh food compartment


6


. Tray


60


generally includes a platform


63


having a substantially planar upper support surface


65


. Upper surface


65


of platform


63


leads to an annular, upstanding peripheral rim


68


. The presence of rim


68


advantageously minimizes the potential of any substance spilled upon upper surface


65


from falling off of platform


63


. As also shown, tray


60


preferably includes a plurality of leg members


71


-


74


which project from a lower surface


76


of platform


63


. In the most preferred form of the invention, leg members


71


-


74


terminate in elastomeric tips as indicated at


78


.




Although various materials can be utilized to form shelf support frame


27


and tray


60


without departing from the present invention, shelf support frame


27


is preferably made of metal, such as aluminum, and tray


60


is preferably formed of a transparent material such as acrylic. With this arrangement, leg members


71


-


74


are integrally formed with platform


63


in order to enhance the overall structurally integrity of tray


60


. When utilized outside of fresh food compartment


6


, tray


60


can be supported with elastomeric tips


78


engaging a planar surface. If tray


60


is utilized to support food items which need to be refrigerated, tray


60


can be readily positioned above shelf support frame


27


within fresh food compartment


6


and lowered such that leg members


71


-


74


extend into respective elongated openings


52


. In this position, lower surface


76


of platform


63


will rest upon the upper surface


49


of each support rail


30


,


31


. In the most preferred form of the invention, the distance between leg members


71


and


72


, as well as the distance between leg members


73


and


74


, is smaller than the length of each opening


52


as clearly indicated in FIG.


1


. With this configuration, tray


60


is permitted to slide, to a limited extent, between fore and aft positions within fresh food compartment


6


. This ability of tray


60


to be shifted relative to shelf support frame


27


and fresh food compartment


6


can advantageously enhance the ability of a user to access food items supported upon a rear portion of platform


63


. In addition, removal of tray


60


is enhanced when tray


60


is repositioned such that a front portion thereof projects forward of shelf support frame


27


.




Based on the above, it should be readily apparent that the combination shelf and serving tray assembly of the present invention can be economically manufactured and represents a versatile arrangement that can be used by a consumer to conveniently store items within a refrigerator and to serve those items. However, although the present invention has been described with respect to a preferred embodiment, it should be readily understood that various changes and/or modifications can be made to the invention without departing from the spirit thereof. For instance, although the upper surface


49


of each support rail


30


,


31


is shown to include an opening


52


in the form of a single elongated slot, it should be recognized that multiple, smaller length slots could also be utilized to perform the same function. In addition, support rails


30


and


31


could be shorter such that a front end of tray


60


extends beyond the rails. In order to prevent tray


60


from flipping due to an abundance of items being placed on the front end of tray


60


, the forward most ends of each opening


52


could be provided with a keyhole


85


such as that indicated in dotted lines in rail member


30


in FIG.


2


. Here, rear leg members


72


and


73


would be diametrically increased while being formed with a reduced diametric portion adjacent support surface


65


. In this manner, the leg members


72


and


73


can only be placed in or removed from openings


52


at the keyholes


85


. It should be noted that tray


60


is preferably constructed symmetrical such that platform


63


can be positioned upon shelf support frame


27


in various configurations, including a reversal of tray


60


from that shown in FIG.


2


. In fact, tray


60


can be made square, such that any one of the sides of tray


60


can be exposed at the front of fresh food compartment


6


at any given time. As an additional modification, it should be noted that leg members


71


-


74


could take various forms including simply providing rubber nubs. In addition, elongated runners could be provided to define the various leg members. Handles could also be incorporated as part of tray


60


. Finally, although shelf support frame


27


is illustrated to be an integrated unit for mounting within fresh food compartment


6


, support rails


30


and


31


of frame


27


need not be interconnected, but rather separate support rails could be individually supported within fresh food compartment


6


in various ways known in the art. In any event, the above description is not intended to be limiting to the invention, but rather illustrative. Therefore, the invention is only intended to be limited by the scope of the following claims.
