For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG. 1. However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
Referring to FIG. 1, a home appliance is shown as a refrigerator appliance 10 (hereinafter, the refrigerator 10). The refrigerator 10 includes a lower frame 24 and a cabinet 12 extending upwardly from the lower frame 24. The cabinet 12 of the refrigerator 10 includes a pair of inner liners 16 that define a pair of inner temperature-controlled compartments that are independently operable to maintain food items stored therein at one or more set temperatures.
The lower temperature-controlled compartment is a freezer compartment 22, and the refrigerator 10 includes a drawer 108 that is positioned in the freezer compartment 22. The drawer 108 is moveable relative to the cabinet 12 such that food items may be placed in the drawer 108 for storage in the freezer compartment 22 and retrieved from the drawer 108 when ready for use. A handle 28 is located on the drawer 108 so that a user may open and close the drawer 108.
The upper temperature-controlled compartment is a fresh food compartment 20 into which a user may place and store food items such as milk, cheese, produce, etcetera. A pair of doors 14 are each hinged to the front of the cabinet 12 via a pair of hinge assemblies 30. The doors 14 permit user access to the fresh food compartment 20 such that food items may be placed in and retrieved from the fresh food compartment 20. A handle 26 is located on each of the doors 14 so that a user may open and close the doors 14.
While the illustrative embodiment of the refrigerator 10 shown in FIG. 1 is a “french-door” model with a pair of doors 14 operable to permit access to the fresh food compartment 20, it should be appreciated that other configurations are contemplated, such as, for example, configurations having only one door 14 operable to permit access to the fresh food compartment 20. Additionally, it should also be appreciated that, in some embodiments, the freezer compartment 22 may be positioned above the fresh food compartment 20 and, in other embodiments, either one of the temperature-controlled compartments may be omitted. It should be further appreciated that, in some embodiments, the refrigerator 10 may include more than one freezer compartment 22 and/or more than one fresh food compartment 20. Configurations of the refrigerator 10 are also contemplated in which the freezer compartment 22 is located on one side of the cabinet 12 and the fresh food compartment 20 is located on the opposite side of the cabinet 12.
As shown in FIG. 1, the refrigerator 10 may also include four adjustable shelves 100 removably mounted within the fresh food compartment 20, upon which a user of the refrigerator 10 may arrange food items. It is contemplated that the refrigerator 10 may include any number of adjustable shelves 100 within the fresh food compartment 20. As the adjustable shelves 100 are removably mounted within the fresh food compartment 20, a user may remove any adjustable shelf 100 and relocate it to any available shelf mounting position within the fresh food compartment 20. It will be appreciated that the refrigerator 10 may additionally or alternatively include other devices for supporting or storing food within the fresh food compartment 20, such as, for example, drawers 32 or door bins 34 (as shown in FIG. 1). As used in the present disclosure, the term “shelf” is to be considered in its broadest sense as any device that will hold a food item, including shelves, drawers, bins, panels, racks, and the like.
The adjustable shelves 100 may be removably mounted within the fresh food compartment 20 using any suitable mechanism. In the illustrative embodiment of the refrigerator 10 shown in FIG. 1, four shelf ladders 126 are disposed within the fresh food compartment 20 to provide a plurality of shelf mounting positions for the adjustable shelves 100. It is contemplated that any number of shelf ladders 126 may be used for removably mounting the adjustable shelves 100. In some embodiments, the shelf ladders 126 may be secured to one or more walls of the fresh food compartment 20 using screws, bolts, rivets, adhesive, or other fixation mechanisms. In other embodiments, the shelf ladders 126 may be integrally formed into one or more walls of the fresh food compartment 20. It should also be appreciated that the adjustable shelves 100 may be removably mounted within the fresh food compartment 20 using any number of mechanisms other than the shelf ladders 126. By way of example, the adjustable shelves 100 may be removably mounted within the fresh food compartment 20 using ledges, tracks, slides, glides, rollers, and the like.
As shown in more detail in FIG. 2, each of the shelf ladders 126 in the illustrative embodiment of refrigerator 10 has a number of slots 128 defined therein. Each of the adjustable shelves 100 may illustratively include a pair of mounting brackets 102 that are spaced apart from one another the same distance as a pair of the shelf ladders 126. The mounting brackets 102 of an adjustable shelf 100 may each engage one or more slots 128 defined in one of the shelf ladders 126 to cantilever the adjustable shelf 100 to a pair of shelf ladders 126. As such, the slots 128 defined in the shelf ladders 126 provide a plurality of shelf mounting positions for the adjustable shelves 100. In the illustrative embodiment, the slots 128 defined in the shelf ladders 126 (and, hence, the shelf mounting positions) are spaced approximately one inch apart. It will be appreciated that other configurations for the spacing of the slots 128 and the shelf mounting positions are possible.
As shown in FIG. 3A-3B, a refrigerator 10 may include a wine rack assembly 110. The wine rack assembly 110 may have a wine rack 112 with a pair of wine rack brackets 114 on either end. The wine rack brackets 114 may be integrally formed to the ends of the wine rack 114, forming the wine rack assembly 114. It is also contemplated that the wine rack brackets may be attached using screws, bolts, rivets, adhesive, or other fixation mechanisms.
The wine rack assembly 110 may rest on a shelf 100 at the rear of the fresh food compartment 20. The wine rack assembly 110 may be rotated up from underneath the shelf 100 such that the wine rack brackets 114 fit in a space between the shelf 100 and the liner 16. The wine rack assembly 110 may rest loosely on the shelf 100, held in place by the force of gravity on the wine rack 112. The wine rack assembly 110 may also be fitted to specific refrigerator designs for the space between the shelf 100 and the rear wall of the cabinet 12. The wine rack brackets 114 may also simply have a portion that extends out from the wine rack bracket 114 toward the rear wall of the cabinet 12 to prevent the wine rack assembly from rotating farther than desired. It is also contemplated that the wine rack assembly may be placed on the shelf 100 before the shelf 100 is located to the shelf ladders 126.
The wine rack 112 may be a plate. The plate thickness may be within a range of 2 mm to 25 mm, preferably about 5 mm in thickness. The wine rack 112 may include a plurality of apertures 120. The apertures 120 may be sized to allow the neck of a conventional wine bottle to pass through the aperture 120 and hold the bottle substantially horizontally in a cantilever fashion. The size of the aperture 120 necessary is a function of thickness of the plate and the angle of the wine rack 112 in its wine bottle storage position. As the thickness of the plate used in the wine rack 112 increases, the diameter D of aperture 120 may also increase to accommodate the neck of a conventional wine bottle. Similarly, as the thickness of the plate used in the wine rack 112 decreases, the diameter D of the aperture 120 may also decrease. The diameter D of the aperture 120 may be between 30 mm and 50 mm, preferably about 35 mm. As the angle α of the wine rack 112 increases, the diameter D of the aperture 120 may decrease. Similarly, as the angle α of the wine rack 112 decreases, the diameter D of the aperture 120 may increase. The angle α of the wine rack 112 may be between 90 and 45 degrees, preferably about 57 degrees.
As shown in FIG. 4A-4C, in another embodiment, the wine rack 112 may be rotatably connected to the wine rack brackets 114. The wine rack 112 may be movable between a first position where it is stowed underneath the shelf 100, and a second position where the wine rack 112 may hold bottles in a preferred position. The wine rack brackets 114 may include round holes 212 and the wine rack 112 may include corresponding round pins 210. The pins 210 and holes 212 may be sized as an interference fit such that the rack 112 stays in the first stowed position when not in use. It is further contemplated that other shapes may be used other than round to act as hard stops for the rack in the first and second positions. It is also contemplated that hinges of a type known in the art may be used between the wine rack 112 and the brackets 114.
In a further embodiment as shown in FIGS. 5A-5B, a wine rack attaches directly to the liner 16. The wine rack 312 may include at least 4 rack pins 310 sized to fit within liner grommets 320 located in the liner 16. The liner grommets 320 are spaced such that the wine rack 312 holds the conventional wine bottle substantially horizontal.
It is also contemplated as shown in FIGS. 5C-5D that the wine rack 312 be rotatable about the upper pin 310 between a first stowed position and a second wine bottle storage position. In this embodiment, the lower pin 310 would be a spring loaded pin assembly 330. The spring loaded spring assembly 330 may include a spring 332, a pin ball 334, and a rack grommet 336. When in the first or second position, the force of the spring 332 may push the pin ball 334 outward from the rack 312. The rack grommet 336 would have a shape to allow the pin ball 334 to extend beyond the end of the rack grommet 336, but remain contained within the rack grommet 336. The portion of the pin ball 334 that extends beyond the end of the rack grommet 336 would extend into the corresponding liner grommet 320, preventing the rack 312 from any undesired movement. While the spring loaded pin assembly 330 prevents undesired movement, it is also designed to be easily moved by a user from one of the first or second position to the other using hand forces only. It has also been contemplated that the refrigerator 10 include a spring loaded wine rack 312 such that the wine rack 312 spring back to the first stowed position when there is no load on the wine rack 312, i.e. when no bottles are being stored.
In another embodiment, as shown in FIG. 6, the wine rack assembly 410 includes a wine rack 412 and a pair of wine rack brackets 414. The wine rack brackets 414 are shaped similarly to the shelf brackets 102 as described in detail above. The wine rack brackets 414 attach to the shelf ladders 126 in the same way as the shelf brackets 102 described above.
As shown in FIG. 7A, in order to accommodate standard wine bottles, the spacing of the apertures 120 on the wine rack 112 should be a minimum of 62 mm, and preferably greater than or about 87 mm. It has been contemplated in order to accommodate many different sized bottles, both standard and non-standard, that the wine rack have one or more non-circle apertures with a width equal to the diameter D as contemplated above. This could be one single rectangle aperture as shown in FIG. 7B, or more apertures either rectangle or oval in shape with a width equal to the diameter D as contemplated above. It has also been contemplated that the wine rack could extend along the entire width of the fresh food compartment in any of the above embodiments. It has further been contemplated that other types of bottles such as bottles of soda or juice, or anything else in a bottle with a neck that may fit into the apertures may be suitable for this rack.
As shown in FIG. 8, in another embodiment, the wine rack 112 also has an upstanding flange 160 upon which a logo or other information could be displayed when the wine rack 112 is in a first position.
