This invention relates generally to an appliance storage member, and more particularly, to a support assembly for an appliance storage bin or storage shelf.
Household appliances typically include storage shelves or storage chambers, such as bins, pans, drawers, and the like. It is useful and desirable to the consumer for the storage chambers and storage shelves to be movable for accessing the contents held by the storage chamber or the storage shelf. The storage chambers and storage shelves are generally suspended from a support structure that includes a track or glide that facilitates sliding movement of the storage chamber or storage shelf in and out of the appliance. Some storage chambers are rotatably mounted within the appliance for accessing the contents of the storage chamber.
While slide-out storage chambers and storage shelves are desirable for convenient access, they can be difficult to use. In at least some known appliances, the storage chambers or storage shelves can unexpectedly come all of the way out of its track, spilling the contents of the chamber or shelf. In other appliances, the travel of the storage chambers or storage shelves are limited so that they only come partially out of the compartment of the appliance, which limits access to the contents of the storage chambers and storage shelves. For example, at least some of these known appliances include two slide assemblies, wherein one slide is coupled to the appliance and the other slide is slidable along the fixed slide. These slides require an overlap for stability of the two slides when the movable slide is extended. As such, the storage shelf or storage chamber is not fully extendable which decreases the usability of the storage shelf or storage chamber. To overcome this problem, other known appliances include three slide assemblies. The third slide allows for full extension of the storage shelf or storage chamber. However, three slide assemblies are more expensive than two slide assemblies.
In one aspect, an appliance is provided including a cabinet having a plurality of cabinet walls defining a compartment, a storage member configured to support an item for storage in the compartment, and a support assembly slidably mounted within the compartment. The support assembly includes a fixed rail mounted to one of the cabinet walls, and a movable rail slidably coupled to the fixed rail and movable along a sliding direction between a retracted position and an extended position. A bracket is slidably mounted to the movable rail and is movable along a sliding direction between a retracted position and an extended position. The sliding direction of the bracket is substantially parallel to the sliding direction of the movable rail. The storage member is fixedly connected to the bracket and movable with the bracket.
In another aspect, a support assembly is provided for a storage member of an appliance having a cabinet with a plurality of cabinet walls defining a compartment, the storage member configured to store an item in the compartment. The support assembly includes a fixed rail mounted to one of the cabinet walls, a movable rail slidably coupled to the fixed rail and movable along a sliding direction between a retracted position and an extended position, and a bracket slidably mounted to the movable rail and movable along a sliding direction between a retracted position and an extended position. The sliding direction of the bracket is substantially parallel to the sliding direction of the movable rail, and the bracket is configured to support the storage member such that the storage member is movable with the bracket.
In a further aspect, a method is provided of assembling a support assembly for an appliance having a cabinet with a plurality of cabinet walls defining a compartment. The method includes coupling a fixed rail of the support assembly to one of the cabinet walls, slidably coupling a movable rail to the fixed rail, slidably coupling a bracket to the movable rail, and fixedly coupling a storage member to the bracket. The storage member is configured to store an item in the compartment, and the bracket movable along a sliding direction with the bracket.
Refrigerator 100 includes an outer case 106 and inner liners 108 and 110. A space between case 106 and liners 108 and 110, and between liners 108 and 110, is filled with foamed-in-place insulation. Outer case 106 normally is formed by folding a sheet of a suitable material, such as pre-painted steel, into an inverted U-shape to form top and side walls of case. A bottom wall of case 106 normally is formed separately and attached to the case side walls and to a bottom frame that provides support for refrigerator 100. Inner liners 108 and 110 are molded from a suitable plastic material to form freezer compartment 104 and fresh food compartment 106, respectively. Alternatively, liners 108, 110 may be formed by bending and welding a sheet of a suitable metal, such as steel. The illustrative embodiment includes two separate liners 108, 110 as it is a relatively large capacity unit and separate liners add strength and are easier to maintain within manufacturing tolerances. In smaller refrigerators, a single liner is formed and a mullion spans between opposite sides of the liner to divide it into a freezer compartment and a fresh food compartment.
A breaker strip 112 extends between a case front flange and outer front edges of liners. Breaker strip 112 is formed from a suitable resilient material, such as an extruded acrylo-butadiene-syrene based material (commonly referred to as ABS).
The insulation in the space between liners 108, 110 is covered by another strip of suitable resilient material, which also commonly is referred to as a mullion 114. Mullion 114 also preferably is formed of an extruded ABS material. It will be understood that in a refrigerator with separate mullion dividing an unitary liner into a freezer and a fresh food compartment, a front face member of mullion corresponds to mullion 114. Breaker strip 112 and mullion 114 form a front face, and extend completely around inner peripheral edges of case 106 and vertically between liners 108, 110. Mullion 114, insulation between compartments, and a spaced wall of liners separating compartments, sometimes are collectively referred to herein as a center mullion wall 116.
Shelves 118 and slide-out drawers 120 normally are provided in fresh food compartment 102 to support items being stored therein. Refrigerator 100 also includes a bottom pan 122 that may be a part of a quick chill and thaw system (not shown in
A freezer door 132 and a fresh food door 134 close access openings to fresh food and freezer compartments 102, 104, respectively. Each door 132, 134 is mounted by a top hinge 136 and a bottom hinge (not shown) to rotate about its outer vertical edge between an open position, as shown in
Storage member 200 includes a frame 204 having a front 206, a back 208, a bottom 210, a first side 212 and a second side 214. A top 216 of storage member 200 is open for accessing a storage chamber 218 of storage member 200 defined by frame 204. Front 206 is at least partially open to allow access to storage chamber 218. In the exemplary embodiment, frame 204 defines a box-shaped storage chamber 218 for supporting items to be held within appliance 100.
Support assembly 202 is provided to support storage member 200. Support assembly 202 includes a first slide sub-assembly 220 and a second slide sub-assembly 222. Each slide sub-assembly 220 and 222 includes slides or rails that facilitate moving storage member 200 between a retracted position and an extended position. In the retracted position, storage member 200 is received within compartment 104 (shown in
In the exemplary embodiment, first slide sub-assembly 220 includes a first inner or fixed rail 230, a first outer or movable rail 232 and a first bracket 234. Fixed rail 230 and movable rail 232 are fabricated from a durable material, such as metal, to withstand the forces and weight of supporting storage member 200. Bracket 234 is fabricated from a different material than fixed rail 230 and movable rail 232. In the exemplary embodiment, bracket 234 is fabricated from a plastic material. In the exemplary embodiment, a lubricant coating is applied to at least one of bracket 234 and movable rail 232 to facilitate movement of bracket 234 with respect to movable rail 232. Second slide sub-assembly 222 is substantially similar to first slide sub-assembly 220 and includes a second inner or fixed rail 236, a second outer or movable rail 238 and a second bracket 240. As first and second slide sub-assemblies 220 and 222, respectively, are substantially similar, the remainder of the disclosure will discuss the features and operations of support assembly 202 in terms of and with respect to first slide sub-assembly 220. It should be understood that second slide sub-assembly 222 includes similar features and operates in a similar manner as first slide sub-assembly 220.
Movable rail 232 is slidably mounted to fixed rail 230. In the exemplary embodiment, a plurality of ball bearings 252 are positioned between fixed rail 230 and movable rail 232, and ball bearings 252 are held within a frame 254. Frame 254 maintains spacing and positioning between ball bearings 252. In the exemplary embodiment, a lubricant coating is applied to at least one of fixed rail 230, movable rail 232, and ball bearings 252.
Fixed rail 230 includes an inner surface 256 and an outer surface 258. Outer surface 258 faces inner liner 110 and is mounted to inner liner 110. Outer surface 258 also faces movable rail 232. Movable rail 232 includes an inner surface 260 and an outer surface 262. Inner surface 260 faces fixed rail 230 and outer surface faces bracket 234. In the exemplary embodiment, ball bearings 252 are snuggly fit between a track defined by outer surface 258 of fixed rail 230 and a track defined by inner surface 260 of movable rail. The tracks are defined by radiused surfaces of fixed rail 230 and movable rail 232. The cooperation between the tracks and ball bearings 252 facilitate coupling movable rail 232 to fixed rail 230.
Bracket 234 includes a base portion 264 that is mounted to movable rail 232 and a hook portion 266 extending from base portion 264. Bracket 234 includes an inner surface 268 facing outer surface 262 of movable rail 232 and facing inner liner 110. Bracket also includes an outer surface 270 facing storage member 200. A portion of outer surface 270 defines a supporting surface 272 for engaging and supporting storage member 200. Supporting surface 272 is substantially planar, and in the exemplary embodiment, is oriented substantially horizontally when assembled. Hook portion 266 is L-shaped and extends upward from supporting surface 272. As such, hook portion 266 and support surface 272 define a channel for supporting and retaining storage member 200 therein. For example, supporting surface 272 resists movement of storage member 200 in a generally vertically downward direction, such as in the direction of arrow A. Hook portion 266 resists movement of storage member 200 in a generally vertically upward direction, such as in the direction of arrow B. Hook portion 266 also resist outward movement of storage member 200 toward inner liner 110, such as in the direction of arrow C.

In an alternative embodiment, in the partially extended position, movable rail 232 is moved with respect to fixed rail 230 to an extended position and bracket 234 remains in the retracted position with respect to movable member 232. As such, one of movable rail 232 and bracket 234 are movable from a retracted position to an extended position as support assembly 200 is moved from the retracted position to the partially extended position. In another alternative embodiment, both movable rail 232 and bracket 234 are moved from respective retracted positions to partially extended positions as support assembly 200 is moved from the retracted position to the partially extended position.

A storage member and support assembly for an appliance is thus provided in a cost effective and reliable manner. The support assembly includes a fixed rail that is coupled to a wall of the appliance and a single movable rail that is slidably coupled to the fixed rail. To facilitate full extension of the storage member, and thus provide easier access to the items stored by the storage member, a bracket is slidably coupled to the movable member. The bracket is movable over a distance that is substantially equal to the amount of overlap between fixed rail and movable rail when the rails are in the extended position. As such, the support assembly allows for full extension of a two rail system, wherein the full extension exposes the entire top of storage member when extended. By using a two rail system as opposed to a three rail system, considerable cost savings are provided to the overall support assembly. Additionally, by providing full extension, access to the entire storage member is provided which is desirable for the consumer and increases the sale point of the appliance.
While the invention has been described in terms of various specific embodiments, those skilled in the art will recognize that the invention can be practiced with modification within the spirit and scope of the claims.
