The present invention generally relates to methods of forming storage assemblies and, more particularly, to methods of making modular fascia assemblies for refrigerators.
Over the years, household refrigerators have evolved to accommodate ever increasing functional demands by users. In addition to preserving food, refrigerators must be functionally versatile, easy to maintain and reasonably priced. Consumers desire refrigerators with adjustable storage compartments that can accommodate a variety of foods and food packagings and that are easily accessible to facilitate cleaning and maintenance. As a result, various manufacturers have offered refrigerators with removable shelves and storage assemblies.
Conventional refrigerators typically include various sized storage assemblies formed of injection molded polymeric components. In order to produce these various-sized storage assemblies, however, a manufacturer must construct a separate mold for each size of component. These molds typically are expensive, add to the cost of the final product, and increase the time required to bring a new product to market.
The present invention generally is directed to modular or multi-component fascia assemblies for refrigerator storage assemblies, refrigerators containing multi-component fascia assemblies and methods of making the refrigerator storage assemblies. Multi-component fascia assemblies used in the refrigerator storage assemblies employ parts that can be used in multiple configurations, thereby potentially reducing the cost and time of manufacturing different fascia with different configurations.
In one embodiment, the present invention comprises a refrigerator having a cooling compartment formed of a top wall, a bottom wall, a rear wall, a first side wall, and a second side wall opposed to the first side wall. A storage assembly is disposed in the cooling compartment. The storage assembly includes a support member attached to a multi-component fascia, which is aligned distal to the rear wall within the cooling compartment. The multi-component fascia comprises a face plate having opposed ends and a pair of end caps attached to the opposed ends of the face plate.
In another embodiment, a fascia assembly for a refrigerator storage assembly includes a face plate having opposed ends and a channel formed therein. A pair of end caps are attached to opposite ends of said face plate. A second plate is disposed in the channel of the face plate and a cap is attached to each pair of end caps.
In a further embodiment, a method of making a refrigerator storage unit includes feeding a metal or polymeric material to an extruder and extruding the material through a die extruder to form an intermediate extrusion. The intermediate extrusion is cut to a predetermined length to form a face plate. The method can also include attaching a pair of end caps to the ends of the face plate to form a fascia assembly and attaching the fascia assembly to a support member to form a refrigerator storage unit.
In still another embodiment, a method of forming a refrigerator storage assembly includes feeding a material to an extruder and extruding the material through a die extruder to form a first intermediate extrusion. The first intermediate extrusion is cut to a first predetermined length to form a first face plate. The method can also include injection molding a first pair of end caps and attaching the first pair of end caps to the ends of the first face plate to form a first fascia. The method can additionally include attaching the first fascia to a first support member to form a first storage unit. Furthermore, a second intermediate extrusion is formed by extruding the material through the die. The second intermediate extrusion is cut to a second predetermined length to form a second face plate, with the first predetermined length being unequal to the second predetermined length. The method can also include attaching a second pair of end caps to the ends of the second face plate to form a second fascia and attaching the second fascia to a second support member to form a second storage unit. The first and the second storage units are mounted in a refrigerator cabinet to form a refrigerator storage assembly.
These and other aspects of the present invention are set forth in greater detail below and in the drawings, which are briefly described as follows.
Referring now in more detail to
The refrigerator storage assemblies 40 and 140 include various combinations of storage units 50, 52, and 250, each of which include a support member with a modular or multi-component fascia assembly 70 or 170 attached. The support members incorporated in the storage units can be shelves, drawers, bins, baskets, pans or similar structures for holding food in a refrigerator.
As shown in
The second plate 71 is disposed in the channel 84 of the face plate 72 and extends between the ends caps 76a and 76b. The second plate 71 can be opaque, but is shown in the figures as translucent to provide visual access to the interior of the storage unit. The second plate 71 is shown as a single-walled body, but could comprise an alternative wall configuration.
The cap 74 is disposed over second plate 71 and extends between the end caps 76a and 76b. The cap 74 has a channel formed therein to receive the upper edge of the second plate 71. The cap 74 is attached to each of the pins of end caps 76a and 76b by one or more fasteners 73, which are shown in
Each of the end caps 76a and 76b includes an interior side, which is proximate one of the ends of the face plate 72, the second plate 71, and the cap 74. Each end cap 76a and 76b includes a face plate socket 78, a second plate socket 79, and a cap socket 75 formed on the interior side to receive the ends of the face plate 72, the second plate 71 and the cap 74, respectively.
When the fascia assembly 70 is assembled, the face plate 72 and the second plate 71 are attached to the end caps 76a and 76b by their engagement with the sockets of the end caps. The second plate 71 also is firmly secured in the fascia assembly 70 through alignment in the channel 84 of the face plate 72 and through engagement with the cap 74. Each end of the cap 74 extends through the cap sockets 75 of the end caps 76a and 76b. The cap 74 is secured to the end caps 76a and 76b by fasteners 73, shown as screws in the figures. Other types of fasteners, such as clips, pins, welds, or the like can be used to attach the components of the fascia assembly 70 together.

The present invention also is directed to methods of forming storage assemblies for refrigerators that include multi-component fascia assemblies. The methods generally include extruding a material through a die to form an intermediate extrusion that is cut to a predetermined length to form a face plate, a second plate, or cap. The extruded piece is attached to a support member, such as a shelf, drawer, bin, pan, basket, etc., to serve as at least a portion of the fascia of a storage unit. The use of extruded components to form the fascia assembly for a refrigerator storage unit facilitates production of storage units of various lengths using the same equipment while eliminating the requirement of obtaining a separate tooling mold for each sized unit, as required in molded components. The fascia assemblies formed by the methods detailed herein, however, can from assemblies that are substantially indistinguishable from assemblies constructed from molded parts.
The polymeric extruder includes a feed hopper connected to a barrel in which one or two conveyor screws are disposed. The screw(s) are rotated to carry the material toward a die. The material can be in a softened state by heat from the shearing actions of the screw(s) and/or by heat supplied to the barrel. The screw then forces or extrudes the material through the die in step 110. Extruding metal material includes placing a billet into equipment that heats the billet to a prescribed temperature. The heated metal then is pushed by a ram through the die. The opening in or formed by the die can have a variety of cross-sections depending upon the structure of the face plate to be formed. For example, the opening can have a cross-section like face plate 72, second plate 71 and/or cap 74 shown in
The material solidifies and cools as it exits the die to form an intermediate extrusion in step 120. The intermediate extrusion has the desired cross-section, such as those shown in
The method also includes in step 150 attaching one or more end caps to the end(s) of the face plate. This step can include interlocking tabs, ribs, notches or other structures formed on the end caps and/or face plate, frictionally engaging the end caps to the face plate, or connecting them together with one or more fasteners, such as clips, screws, pins, adhesives or the like.
As shown in
The first face plate is formed in step 240 from the portion of the intermediate extrusion cut to a first predetermined length, and the second face plate is formed in step 340 from the portion of the intermediate extrusion cut to the second predetermined length. As with the method of
Other steps include attaching in step 250 a first pair of end caps to the ends of the first face plate and attaching in step 255 a second pair of end caps to the second face plate. These attachments can be formed by any variety of different processes detailed herein. These intermediate steps of forming and attachment can, but need not, be the same for the first and second face plates.
As shown in
Additionally, the method of
Each of the methods of forming refrigerator storage assemblies described herein can include aligning a translucent, metal or polymeric second plate in a channel formed in the side wall of the face plate, in which the end-caps of the storage assembly engage the sides of the second plate. Additionally, the methods including this step can include an additional step of disposing a cap over the second plate. The cap can be engaged by the end caps of the assembly. Each of the methods can include the step of embossing the face plate to provide on the storage assembly one or more designs and/or indicia, such as the stylistic designs and company logos.
While the present invention has been described in detail herein in accord with certain embodiments, modifications can be made by those skilled in the art that fall within the scope of the invention.
