In yet other embodiments in which a heat source is not to be used, support 30 may be omitted.

Food serving unit 12B is similar to food serving unit 12A except that food serving unit 12B comprises a unit coupled to unit 12A and also configured to contain and present food. Like unit 12A, unit 12B is configured to be put upon a table, counter or other surface elevated above the floor or ground or to alternatively be suspended above the floor or ground and other vertical surface. Food serving unit 12B includes housing 40, legs 42A and 42B (collectively referred to as legs 42), legs 22A, 22B, and underlying ice-steam pan (not shown) and food pan 46. Housing 40 is similar to housing 20 except that housing 40 is generally arcuate shaped. Like housing 20, housing 40 has an annular upper opening into which an underlying ice/steam pan (not shown) and pan 46 are received, wherein the rim of the underlying ice/steam pan and rim 52 of pan 46 rest upon housing 40. As a result, the underlying ice/steam pan and pan 46 may be lifted and removed from housing 40 for cleaning, filling or replacement. In particular embodiments, underlying ice/steam may be omitted. Like housing 20, housing 40 further at least partially conceals those portions of the underlying ice/steam pan and pan 46 that are received within housing 40.

Legs 42A and 42B comprise elongate structures configured to support housing 40 above an underlying table, counter or other generally horizontal surface which is itself spaced or elevated above the floor or ground. In yet other embodiments, legs 42A and 42B may alternatively be configured to be mounted to a vertical or inclined surface so as to elevate food serving unit 12B above the ground or floor. Although illustrated as being substantially identical in configuration to legs 22A and 22B yet having a reduced length or height, legs 42A and 42B may alternatively have different configurations as compared to legs 22A and 22B and may have the same height or a greater height.

In the particular example illustrated, legs 42A and 42B are removably coupled to housing 40. In one particular embodiment, legs 42A and 42B are configured to be separated and removed from housing 40 without the use of tools and without manipulation of one or more fasteners. As a result, unit 12B may be more easily disassembled for transportation or storage and legs 42A, 42B may be more easily repaired or replaced as needed. In yet other embodiments, legs 42A, 42B may be removably coupled to housing 40 by one or more fasteners. In yet other embodiments, legs 42A, 42B may alternatively be affixed or permanently secured to housing 40 such as with welding, bonds, rivets and the like. In yet other embodiments, legs 42A, 42B may be integrally formed as part of a single unitary body with housing 40.

Legs 22A, 22B comprise the same legs as that of food serving unit 12A. Because food serving unit 12A and food serving unit 12B share a common pair of legs (legs 22A and 22B), food serving arrangement 10 is more compact and occupies less horizontal space. In addition, food serving arrangements 10 utilizes fewer parts and has a more simpler aesthetic appearance.

According to one embodiment, housing 40 of food serving unit 12B is removably coupled to each of legs 22A and 22B. As a result, food serving arrangement 10 is modular in nature, enabling food servicing unit 12B to be added or removed with respect to food serving unit 12A as described. In particular embodiments, legs 22A, 22B are also removably coupled to housing 20 of food serving unit 12A. In yet other embodiments, legs 22A, 22B may alternatively be permanently affixed to housing 40 while being removably connectable to housing 20.

The underlying ice/steam pan (not shown) and pan 46 are similar to pans 24 and 26, respectively, of food serving unit 12A except that such pans are arcuate in shape. In particular embodiments, the underlying ice/steam pan may be omitted. In some embodiments, food serving unit 12B may additionally include a heat source support such as heat source support 30 shown in FIG. 2.

Food serving unit 12C is substantially identical to food serving unit 12B except that food serving unit 12C shares legs 22C and 22D of food serving unit 12A instead of legs 22A and 22B. In addition to legs 22C and 22B, food serving unit 12C includes legs 42C and 42D in lieu of legs 42A and 42B. Legs 42C and 42D are substantially identical to legs 42A and 42B. Those remaining elements of food serving unit 12C which correspond to elements of food serving unit 12B are numbered similarly.

Food serving unit 12D comprises a unit configured to contain food or other items which is coupled to units 12A and 12B. In the particular example illustrated, unit 12D supports food or other contents at a height distinct from that of unit 12B which also supports food or other contents at a height distinct from that of unit 12A. As a result, units 12A, 12B and 12D provide a stair-step effect, enabling the contents of such units to be more easily viewed and accessed while reducing space requirements.

Food serving unit 12D generally includes housing 60, leg 62, legs 22A, 42A, and pan 66. Housing 60 comprises one or more structures configured to support pan 66. In the particular example illustrated, housing 60 further conceals a portion of pan 66. In one embodiment, housing 60 is similar to housing 20 and housing 40 except that housing 60 is triangular in shape. Like housing 20 and 40, housing 60 has an upper opening into which pan 66 is received, enabling housing 60 to conceal a lower portion of pan 66. At the same time, this opening enables pan 66 to be lifted and removed from housing 60 for cleaning, filling or replacement. In yet other embodiments, housing 60 may alternatively be fastened to pan 66, may be permanently affixed to or secured to pan 66 by welds, adhesives or rivets and the like or may be integrally formed as part of a single unitary body with pan 66. In other exemplary embodiments, an additional pan may be provided below pan 66 (or any of the other “upper” pans) to provide additional functionality and capabilities (e.g., an underlying ice/steam pan or the like).

Leg 62 comprises an elongate structure coupled to housing 60 and configured to support housing 60 relative to an underlying table, counter or other surface elevated above the ground or floor. In other embodiments, leg 62 may alternatively be configured to be suspended above the ground or floor rather than resting upon a surface elevated above the ground or floor. In the example illustrated, leg 62 has a similar configuration to that of legs 22A and 42A yet has a reduced height. In other embodiments, leg 62 may have a different configuration as well as a different height.

In the particular example illustrated, leg 62 is removably coupled to housing 60, enabling leg 62 to be separated or removed from housing 62 for repair or replacement. In one particular embodiment, leg 62 is configured to be separated or removed from housing 60 without the use of tools and without the need for manipulating one or more fasteners. As a result, leg 62 may be easily disassembled from housing 60. In yet other embodiments, leg 62 may be removably coupled to housing 60 by one or more fasteners. In still other embodiments, leg 62 may be bonded to housing 60 by welds, adhesives, rivets and the like. In still other embodiments, leg 62 may be integrally formed as part of a single unitary body with housing 60.

Legs 22A and 42A comprise the same legs as that of food serving unit 12A and unit 12B. As a result, the compactness of food serving arrangement 10 is further enhanced, reducing the overall surface space required for arrangement 10. The space savings of food serving arrangement 10 is especially enhanced in that a single leg 22A is shared by three food serving units 12A, 12B and 12D. In those embodiments in which food serving unit 12D is removably coupled to legs 22A and 42A, with food serving arrangement 10 as enhanced modularity in that food serving units 12A, 12B and 12D may each be selectively added or removed as needed or desired.

Food serving unit 12E is similar to food serving unit 12D except that food serving unit 12E shares legs 22C and 42C in lieu of legs 22A and 42A. Those remaining elements of food serving unit 12D which correspond to elements of food serving unit 12D are numbered similarly. Like food serving unit 12D, food serving unit 12E provides arrangement 10 with reduced space consumption by sharing legs 22C and 42C. Food serving unit 12E also provides a stair-step effect for displaying and presenting food or other contents. In those embodiments in which unit 12E is removably connected to units 12A and 12C, unit 12E provides arrangement 10 with enhanced modularity to meet varying needs.

Food pan 66 is similar to food pans 26 and 46 except that food pan 66 is generally triangular in shape. Like pans 26 and 46, pan 66 is configured to contain food and has a basin portion that is at least partially received within and concealed by housing 60. Like pans 26 and 46, pan 66 has a rim 72 which rests upon housing 60 to support pan 66 above housing 60. As a result, pan 66 may be lifted and removed for cleaning, filling or replacement. In other embodiments, pan 66 may be removably fastened to housing 60 or may be integrally formed as a single unitary body with housing 60.

FIG. 2 is an exploded perspective view illustrating food serving unit 112, one particular embodiment of food serving unit 12A shown in FIG. 1. Food serving unit 112 is similar to food serving unit 12A except that food serving unit 112 specifically includes housing 120 and legs. The legs may be legs 2012A, 2012B, 2012C and 2012D as shown, for example, in FIGS. 2, 8A, 8B, 9A, 9B, 10A, 10B, 31, 33 (collectively referred to as legs 2012), legs 122A, 122B, 122C, 122D (collectively referred to as legs 122 in FIGS. 4-7), or other legs that are shown and/or described herein. Food serving unit 112 additionally includes feet 125 and caps 127. Housing 120 comprises a three-dimensional structure configured to support pans 24 and 26 while being supported itself by legs 2012. Housing 120 includes frame 180 and sides 182, 183. Frame 180 comprises an elongate flange or other structure forming an opening 184. Opening 184 is configured to receive a lower portion of pan 24 such that the lower portion of pan 24 is concealed by sides 182 and 183. At the same time, frame 180 supports rim 32 of pan 24 (or rim 34 or pan 26 when pan 24 is omitted), enabling pan 24 and pan 26 to be lifted from opening 184 for cleaning, filling, emptying or replacement. In other embodiments, frame 180, also known as a rim, may alternatively be fastened, fixed or integrally formed with pan 24. Those remaining elements of food serving unit 112 which correspond to elements of food serving unit 12A are numbered similarly.

Sides 182 and 183 extend non-parallel from frame 180 to form gaps or channels 186. As will be described in detail hereafter, channels 186 facilitate releasable or removable connection of housing 120 to legs (legs 122, legs 2012, or the like). In the particular example illustrated in which housing 120 is generally rectangular, sides 182 and 183 extend substantially perpendicular to one another such that channels 186 are located at the four corners of housing 120. In other embodiments, sides 182 and 183 may extend at other angles relative to one another so as to form a greater or fewer number of such channels 186. For example, in other embodiments, housing 120 may be triangular in a fashion similar to that of housing 60 (shown in FIG. 1), wherein housing 120 would alternatively have three sides forming three channels 186. Although sides 182 and 183 are illustrated as being generally flat linear or planar panels, in other embodiments, sides 182 and 183 may be non-linear or non-planar and may also be configured such that opposite sides 182 or opposite sides 183 are not parallel to one another. For example, in other embodiments, housing 120 may include sides 182 and 183 configured similar to that of the sides of housing 40 (shown in FIG. 1).

FIG. 3 illustrates one example method by which housing 120 may be formed. FIG. 3 illustrates a sheet, panel or pattern 120′ from which housing 120 is formed. In one embodiment, pattern 120′ comprises a sheet or panel of metal, such as stainless steel which is stamped or otherwise cut to the configuration shown in FIG. 3. In other embodiments, pattern 120′ may be molded or fabricated using other techniques. In lieu of being formed from stainless steel, in other embodiments, pattern 120′ may be formed from other metals or may be formed from other deformable materials.

As shown by FIG. 3, pattern 120 includes opening 184 and sides 182, 183. Sides 182 and 183 are interconnected and have consecutive edges 188. Upon deformation of pattern 120′ to form housing 120 (shown in FIG. 2), edges 188 remain spaced from one another to form channels 186 (shown in FIG. 2). The described method for forming housing 120 enables housing 120 to be easily fabricated at a low cost. In other embodiments, housing 120 may be formed from other fabrication methods.

The legs support housing 120 above an underlying table, counter or other surface which is itself elevated above the floor or ground. In other embodiments, legs 122 may merely serve as a connecting structure facilitating connection of unit 112 to other food serving units. FIG. 4 is a sectional view of leg 122A illustrating leg 122A in more detail. As shown by FIG. 4, leg 122A generally extends along axis 190 and includes hub 192, opening 194, fingers 196 and channels or grooves 198. Hub 192 comprises that portion of leg 122A extending about opening 194 and supporting fingers 196. Hub 192 comprises the structure strength of leg 122A while providing opening 194. Opening 194 provides a cavity for receiving and connecting feet 125 to a lower end of leg 122A and for receiving and connecting a portion of cap 127 to leg 122A. In the particular example illustrated, opening 194 extends along an entire axial length of leg 122A. In other embodiments, opening 194 may be located at both a top and a bottom of leg 122A. In still other embodiments, opening 194 may have other configurations or may be omitted where other methods are utilized for connecting foot 125 and cap 127 to leg 122A. In particular embodiments where one or both of foot 125 and cap 127 are omitted, opening 194 may be omitted either at the bottom or top of leg 122A.

Fingers 196 extend radially outward from hub 192 and are spaced from one another so as to form grooves 198. Fingers 196 and grooves 198 cooperate to serve as connection portions for leg 122A by receiving respective edges 188 of sides 182 and 183 of housing 120 as best seen in FIG. 5. In the particular example illustrated, as shown in FIG. 5, housing 120 is connected to leg 122A by aligning a lower portion of edges 188 with respective grooves 198 and sliding edges 188 into and along grooves 198. As a result, leg 122A may be secured to housing 120 without additional fasteners or without the need for tools. At the same time, housing 120 is securely connected to leg 122A.

In the particular example illustrated, leg 122A includes fingers 196 and grooves 198 at a plurality of circumferential positions about axis 190. As a result, leg 122 may be simultaneously connected to multiple distinct housings such as housing 120 shown in FIG. 2 or such as housings 40 and 60 shown in FIG. 1, when such housings 40 and 60 have edges 188 and channels 186 similar to that of housing 120. As a result, leg 122A may be utilized to connect multiple food serving units, wherein such food serving units share leg 122A to reduce space consumption and minimize part count and set up costs. Moreover, because the connection portions provided by fingers 196 and grooves 198 are angularly spaced from one another about axis 190, such interconnected food serving units may also be positioned at a variety of angular positions with respect to one another including non-parallel and non-perpendicular angular positions with respect to one another.

In the particular example illustrated, leg 122A includes fingers 196 and grooves 198 which continuously circumferentially extend about axis 190 to facilitate interconnection of food serving units at a multitude of relative angular positions with respect to one another. In other embodiments, leg 122A may alternatively have fingers 196 and grooves 198 non-uniformly positioned about axis 190. For example, in other embodiments, leg 122A may be specifically configured to be connected to a set number of housings or to connect such housings at a predetermined selected angles with respect to one another. In still other embodiments, leg 122A may have other structures configured to facilitate movable connection of multiple food serving units to one another about or with respect to axis 190. For example, in lieu of having channels 198 that receive portions of housing 120, in other embodiments, housing 120 may include a channel configured to receive a corresponding male projection extending from leg 122A. In particular embodiments, edges 188 may have bulbous or rounded cylindrical ends which slide within corresponding cylindrical grooves 198 to enhance mating of such housings with leg 122A.

According to one example embodiment, leg 122A is formed from a polymer. In other embodiments, leg 122A may be formed from a metal. Due to its symmetrical configuration about axis 190, leg 122A may be extruded to reduce the fabrication costs. In other embodiments, leg 122A may be formed from other materials and other fabrication methods. For example in other embodiments, leg 122A may be formed from wood or combinations of multiple materials.

In other embodiments, leg 122A may have other male and female interlocking structures.

Legs 122B, 122C and 122D are substantially identical to leg 122A. According to one embodiment, each of legs 122A-122D is configured so as to have a length or height such that a top end of each leg 122 extends in close proximity to frame 180 of associated housing (housing 120) assembled and supporting the associated housing. In the particular example illustrated, legs 122 each have a height or length less than or equal to about 2 feet. In one embodiment, each leg has a height or length less than or equal to about 12 inches. As a result, legs 122 do not substantially project well beyond frame 180 so as to interfere with axis to food contained within the food serving unit. When supporting housings having a lesser height, legs 122 are further shortened depending upon the height of the particular food serving unit of the adjacent particular food serving unit. For example, in embodiments where legs 42 of food serving unit 12B are configured in a manner similar to that of legs 122, legs 42 also have a height such that the top of legs 42 are in close proximity to a top of housing 40. In one example embodiment, legs 42 have a height of less than or equal to about six inches. In those embodiments in which legs 62 of food serving units 60 are configured in a manner similar or identical to that of legs 122, legs 62 have a height of less than or equal to about three inches. In those embodiments in which legs 22 of food serving units are configured in a manner similar or identical to that of legs, legs 22 have a height of less than or equal to about nine inches. Such lengths facilitate the positioning of food serving arrangement 10 or any other food serving arrangement including legs similar to that of legs 122 to be positioned upon a table, counter or other horizontal surface elevated above the floor or ground while providing persons a relatively unobstructed view and access to food displayed and contained by the various food serving units of the food serving arrangement. In alternative embodiments, the legs may extend above the top surface of the housing and/or the pan.

Feet 125 comprise structures configured to be connected to a lower end of each of legs 122 so as to stably support legs 122 upon a surface such as a table or countertop. FIG. 6 illustrates one of feet 125 connected to one of legs 122. As shown by FIG. 6, each foot 125 has an enlarged base portion 204 and reduced diameter boss 206. Base 204 rests upon a surface such as a table or counter while boss 206 projects into opening 194 of leg 122A to a close frictional fit with the interior of opening 194. In other embodiments, foot 125 may additionally be secured to leg 122 by adhesives, welding or fasteners. In addition to supporting leg 122 above a surface, foot 125 further engages a lower end of housing 120 to limit the downward movement of housing 120 relative to leg 122A so as to control the height of housing 120 above the table, counter or other surface upon which food serving unit 112 rests. In yet other embodiments, foot 125 may be omitted.

As shown by FIG. 7, caps comprise structures configured to connect to an upper end of legs 122. As shown by FIG. 7, each cap is partially received within opening 194 of leg 122 and projects above and beyond leg 122. Each cap 127 covers opening 194 and assists in retaining housing 120 in connection with leg 122A. To separate housing 120 from leg 122A, cap 127 connected to leg 122A is lifted and removed and housing 120 is lifted relative to leg 122A so as to slide edges 188 (shown in FIG. 3) from grooves 198 (shown in FIG. 4). In other embodiments, caps 127 may be omitted.

Overall, food serving unit 112 provides a unit that may be broken down and disassembled without tools and without manipulation of one or more fasteners. Likewise, food serving unit 112 may be quickly and easily assembled at a site or when needed. In the particular example illustrated in which housing 120 is formed from deformed sheets of polymeric or metal material and when legs 122 are extruded, unit 112 is manufactured at a reduced cost. Moreover, legs 122 enable unit 112 to be quickly and easily joined to other food serving units in a variety of different relative angular positions and at different heights to form an aesthetically attractive and highly functional food serving arrangement such as food serving arrangement 10 shown in FIG. 1. In addition, food serving arrangement 112 may be modified so as to support single pan 26 or additional pans such as pan 24 at various desired heights so as to present food and so as to maintain food at, above or below room temperature.

FIGS. 8A, 9A and 10A are perspective views illustrating food serving units 112, 212 and 312, respectively. FIGS. 8B, 9B and 10b are sectional views of units 112, 212 and 312, respectively. Food serving unit 112 is described above with respect to FIGS. 2-7. FIG. 8B additionally illustrates a heat source (shown as a sterno 207) positioned within heat source holder 30.

Housing 220 is similar to housing 120 except that housing 220 has sides with a reduced height. Likewise, legs 222 are similar to legs 122 except that legs 222 have a correspondingly reduced height. In the example illustrated, legs 122 of unit 112 have a height sufficient so as to elevate pan 24 above a heat source, such as heat source 207. Legs 222 have a height sufficient so as to elevate pan 24 above the underlying table or counter surface. As a result, unit 112 is well suited for containing food that must be maintained at a temperature above room temperature, wherein heat from heat source 207 heats water within pan 24 and the converted steam maintains food within pan 26 at the elevated temperature. In contrast, unit 212 is well suited for maintaining food at a temperature below room temperature, wherein pan 24 may contain ice for cooling contents of pan 24.

Food serving unit 312 is similar to food serving unit 112 except that food serving unit 312 omits pan 24, and includes housing 320 and legs 322 in lieu of housing 120 and legs 122. Housing 320 is similar to housing 120 except that housing 320 has a reduced height. Likewise, legs 322 are similar to legs 122 except that legs 322 also have a reduced height. Legs 322 have a height sufficient so as to elevate pan 34 above the underlying table or counter surface. Because legs 322 do not need to elevate pan 24, which is omitted, legs 322 may have such a reduced height. As a result, unit 312 is well suited for containing food that need not necessarily be heated or cooled while being provided.

FIG. 11 illustrates food serving unit 412, another embodiment of food serving unit 112.

Legs 522A and 522B are similar to legs 122B and 122D except that legs 522A and 522B are longer such that legs 522A and 522B substantially project above pan 26 so as to support back 560 in an inclined or vertical orientation above pan 26. In the particular example illustrated, legs 522A and 522B extend above pan 26. In particular embodiments, legs 522A and 522B may additionally support overhang 564.

Back 560 comprises a largely 2-dimensional structure suspended, hanging or otherwise supported between legs 522A and 522B. In one embodiment, back 560 may be formed from an opaque material such as metal, polymer or cellulose panel. In particular embodiments, back 560 has a thickness sufficiently thin and a sufficient rigidity such that back 560 may be slid within opposite grooves 198 of legs 522A and 522B so as to be held in place prior to positioning of caps 127 upon legs 522A and legs 522B. In one embodiment, back 560 may include alphanumeric symbols, graphics, or other color or art work describing characteristics of the contents of pan 26. In particular embodiments, back 560 additionally serves as a splash guard to reduce the trajectory of food or other contents being removed from pan 26. In the particular example illustrated, back 560 additionally supports lights 560 and any electrical circuitry, componentry or wiring associated with lights 562. In the example illustrated, back 560 also supports overhang 564.

Lights 562 comprise elements configured to emit electromagnetic radiation upon the contents of pan 26. In one embodiment, lights 562 emit visible light so as to enhance viewing of such contents. In yet another embodiment, lights 562 may alternatively or additionally emit infrared light or other electromagnetic radiation so as to cause the heating of contents of pan 26. In still other embodiments, elements 562 may be omitted. Overhang 564 comprises an elongate panel or other structure extending over and above pan 26 and its contents. In one embodiment, overhang 564 is directly connected to and supported by backing 560. In yet other embodiments, overhang 564 may be directly connected and supported by legs 522A, 522B. In one embodiment, overhang 564 is transparent or translucent so as to permit the contents of pan 26 to be viewed from above while being substantially imperforate so as to block airborne contaminants from falling upon the contents of pan 26. In such an embodiment, overhang 564 serves as what may be known as a breath guard. In still other embodiments, overhang 564 may be opaque and/or may include alphanumeric symbols or graphics. In still other embodiments, overhang 564 may be omitted.

FIG. 13 illustrates food serving unit 612, another embodiment of food serving unit 112.

FIG. 31 is a fragmentary exploded perspective view illustrating a portion of food serving unit 2012, another embodiment of food serving unit 112 (shown in FIG. 2). Food serving unit 2012 is similar to food serving unit 112 except that food serving unit 2012 includes legs 2022 in lieu of legs 122 and additionally includes connection interfaces 2025 (one of which are shown). Like food serving units 112, food serving unit 2012 additionally includes pan 32, pan 34, cover 28, heat source support 30, feet 125 and caps 127 (shown in FIG. 2). In other embodiments, one of more of such components may be omitted.

Legs 2022 are similar to legs 122 (shown in FIG. 2) except that legs 2022 include channels or grooves 2098 in lieu of channels 198. Channels 2098 comprise elongate cavities configured to interconnect with connection interfaces 2025. In the particular embodiment illustrated, grooves 2098 comprise T-shaped grooves configured to receive portions of one or more interfaces 2025. In the particular example illustrated, each leg 2022 includes multiple grooves 2098 circumferentially spaced about an axis of leg 2022. Such grooves 2098 axially extend along a substantial entirety of leg 2022, facilitating extrusion of leg 2022. In other embodiments, grooves 2098 may alternatively be circumferentially located in a non-uniform fashion about the axis of leg 2022 or may alternatively extend along only selected axial portions of leg 2022. In still other embodiments, grooves 2098 may have other configurations depending upon the configuration of interface 2025. For example, in another embodiment, leg 2022 may alternatively include one or more tongues radially extending from leg 2022 and configured to be received within a corresponding groove of interface 2025.

Although FIG. 31 illustrates leg 2012 and interface 2025 as part of a single food serving unit 2012, such legs 2022 and interfaces 2025 may be used to interconnect illustrated food serving unit 2012 to one or more other food serving units in various arrangements such as the other food serving arrangements described in FIGS. 1-30.

Connection interface 2025 comprises one or more structures configured to facilitate interconnection of a housing, such as housing 120 shown in FIG. 2, or such as any one of the other housings described with respect to FIGS. 1-30, to associated legs 2022. Connection interface 2025 generally includes body 2026, housing connection portions 2027, 2029 and projections 2037, 2039. Body 2026 comprises a base or other structure from which connection portions 2027, 2029 and projections 2037, 2039 extend. Body 2026 interconnects such portions. In the particular example illustrated, body 2026 closely conforms to the outer circumferential surface of leg 2022 to facilitate close interconnection between housing, such as housing 120, and leg 2022. In other embodiments, body 2026 may have other configurations.

Housing connection portions 2027 and 2029 extend from body 2026 and are configured to be connected to a housing, such as housing 120. In the particular example illustrated, connection portions 2027 and 2029 comprise grooves or channels configured to slidably receive and capture adjacent edges 188 extending along groove 186 of housing 120 as shown in FIG. 33. In one particular embodiment, edges 188 extending along opening 186 of housing 120 (shown in FIG. 2) are slid into connection portions 2027 and 2029, whereby housing 120 is secured to interface 2025. In addition to facilitating interconnection of housing 120 to leg 2022, interface 2025 further rigidifies and strengthens housing 120 along edges 188 and covers such edges 188. In particular embodiments, interface 2025 may be coupled to housing 120 to protect edges 188 during storage or shipment prior to connection to a leg 2022.

In the particular example illustrated, connection portions 2027 and 2029 are angularly spaced from one another by approximately 90 degrees, facilitating connection of interface 2025 to edges 188 which are also oriented at 90 degrees relative to one another. In other embodiments, the angular spacing between connection portions 2027 and 2029 may be different to accommodate connection of interface 2025 to other housings, such as triangular housings, arcuate housings and the like, wherein such edges 188 may be at other angles with respect to one another. In yet other embodiments, connection portions 2027, 2029 may have other configurations configured so as to interconnect interface 2025 to a housing in other manners.

Projections 2037, 2039 comprise structures extending from body 2026 that are configured to connect interface 2025 to one of legs 2022. In the particular example illustrated, projection 2037 comprises a T-shaped tongue configured to be slidably received within one of grooves 2098 of leg 2022 as shown in FIG. 31. Projection 2039 comprises a L-shaped projection configured to be received within adjacent one of grooves 2098 of leg 2022. As a result, interface 2025 may be interconnected to leg 2022 as well as a housing such as housing 120 without the need for tools and without the need to manipulate one or more fasteners. In other embodiments, connection portions 2037, 2039 may have other configurations. For example, in other embodiments, interface 2025 may omit connection portion 2039 or connection portion 2037 may alternatively comprise a channel or groove configured to receive and capture a corresponding projection extending from leg 2022.

FIG. 34 illustrates connection interface 2045, another embodiment of connection interface 2025. Connection interface 2045 is similar to connection interface 2025 except that connection interface 2045 is configured to be connected to a housing having edges 188 having different angular relationships. In the particular example illustrated, interface 2045 includes connection portions 2027, 2029 which are angularly spaced from one another by 60 degrees such that connection portions 2027, 2029 receive edges 188 (shown in FIG. 2) of a housing which are angularly spaced from one another by 60 degrees rather than 90 degrees. In still other embodiments, interface 2045 may angularly space connection portions 2027, 2029 by other degrees such as 30 degrees or other angles depending upon the angular spacing between the adjacent edges of a housing.

As further shown by FIG. 34, interface 2045 omits projection 2039, wherein projection 2037 is configured to be received within one of grooves 2098 of leg 2022 (shown in FIGS. 31 and 33). Like interface 2025, interface 2045 further protects edges 188 of the associated housing to which it is connected during shipping, transport and the like, as well as strengthens and rigidifies the housing to which it is connected.
