As stated above, an improved system is desired for packing, storing, and shipping extractor hoods. Embodiments of the invention provide such an improved system.

FIG. 1 shows an example of an extractor hood 100 in accordance with embodiments of the invention. In this example, extractor hood 100 has a main body 110 that houses a plurality of elements. Extractor hood 100 has, in this example, four lights 130 that can project light onto a cooking surface and/or other surface located below extractor hood 100. Extractor hood 100 also has a filter, or plurality of filters, 120. Filter 120 covers an inlet (not shown) to a fan that produces an airflow upward and through extractor hood 100. An exhaust duct (not shown) can extend from filter 120 upward through a chimney cover 140 and into building structure above extractor hood 100 or some other route that channels extracted gases and/or particles away from extractor hood 100. In some installations, the extracted gases and/or particles are channeled to a vent that is located outside of the building in which extractor hood 100 is located. In this example, chimney cover 140 includes four pieces that are connected to each other to form a telescoping arrangement. First piece 142 of chimney cover 140 attaches to second piece 144 of chimney cover 140 by, for example, friction clips to form an outer section of chimney cover 140. In other embodiments, first piece 142 and second piece 144 are attached to each other by screws, rivets, or other fasteners. Third piece 146 of chimney cover 140 attaches to fourth piece 148 of chimney cover 140 by, for example, friction clips to form an inner section of chimney cover 140. In other embodiments, third piece 146 and fourth piece 148 are attached to each other by screws, rivets, or other fasteners. The outer section of chimney cover 140 can be positioned at different locations relative to the inner section of chimney cover 140 in order to provide adjustability in the length of chimney section 140. In some embodiments, the outer section of chimney cover 140 can slide relative to the inner section of chimney cover 140. In other embodiments, the outer section of chimney cover 140 is assembled at its final position relative to inner section of chimney cover 140 and the two sections do not move relative to each other. In some embodiments, the inner section of chimney cover 140 is fastened to the outer section of chimney cover 140 by screws, rivets, or other fasteners.

Extractor hood main body 110 and/or chimney cover 140 can be stainless steel, copper, other metal, or a non-metallic material.

Which FIG. 1 shows an example of an extractor hood in accordance with embodiments of the invention, other configurations of extractor hoods can also be provided.

FIG. 2 shows an example of a packing system 200 that safely and efficiently packages exhaust hood 100 for transport, shipping and/or delivery. In this example, packing system 200 includes four corner members 210 that position the remaining pieces of packing system 200 in a box or other outer container (not shown). Corner members 210 can be cardboard, plastic, or some other material. Corner members 210 can cushion the remaining pieces of packing system 200 from impacts suffered by the box or other outer container. Such cushioning can be the result of deformation, either plastic or elastic, of corner pieces 210.

In this example, packing system 200 includes two packing holders 300 (explained in more detail below) spaced apart from one another and holding several pieces of extractor hood 100. Below the lower packing holder 300 is a space for main body 110 of extractor hood 100. In this example, main body 110 is located in a main body box 240 that can be a cardboard box, plastic box, some other material box, or a wrapping such as foam or bubble wrap. Main body box 240 is held in position by, in this example, two end main body box supports 230 and a central main body box support 220. In some embodiments, main body 110 of extractor hood 100, and thus main body box 240, are of a size that one or more spacers 250 are provided to hold end main body box supports 230 in position. In some embodiments, main body 110 of extractor hood 100, and thus main body box 240, is large enough that no spacers 250 are needed. By orienting main body box 240 horizontally and placing it below packing holders 300, the resulting package can tend to be bottom heavy and thus more stable when multiple packages are stacked for shipping and/or storage. The embodiment shown in FIG. 2 is just one example of how and where main body 110 is packaged by packing system 200.

In the embodiment shown in FIG. 2, packing holders 300 hold first piece 142 of chimney cover 140 and second piece 144 of chimney cover 140 at one end of packing holders 300; third piece 146 of chimney cover 140 and fourth piece 148 of chimney cover 140 at another end of packing holders 300; and a chimney frame 150 and a transition piece 160 at a central area of packing holders 300. In embodiments, chimney frame 150 is a structural member, or members, that attaches main body 110 of extractor hood 100 (or some other part of extractor hood 100) to the building structure above extractor hood 100. In embodiments, chimney frame 150 is hidden in the final installation by chimney cover 140. In embodiments, transition piece 160 is a piece of duct that transitions from one cross-sectional shape, such as a rectangle, to another cross-sectional shape, such as a circle, to transition the exhaust duct from one cross-section to another. Transition piece 160 is located, in this example, above main body 110 and inside chimney frame 150 in the final installation.

FIG. 3 is a side view of packing system 200 and shows the relative positions of second piece of chimney cover 144, chimney frame 150, and fourth piece of chimney cover 148 between the upper packing holder 300 and the lower packing holder 300.

FIG. 4 is a top view of packing system 200 and shows transition piece 160 located in a central area of the lower packing holder 300.

FIG. 5 is an end view of packing system 200 and shows the spacing of the two packing holders 300.

FIG. 6 shows packing holder 300 having an outer surface 310 having three main areas, a first area 312, a second area 316, and a central area 314 located between the first are 312 and the second area 316. First area 312, second area 316, and central area 314 correspond to first, second, and central receiving portions, respectively, on an inner side of packing holder 300 (shown FIG. 7). Also shown in FIG. 6 are an end surface 321 and a side surface 330. Side surface 330 includes surfaces 331, 332, 333, 334, 335, 336 and 337. In this example, end surface 321 and side surface 330 are perpendicular to outer surface 310.

First area 312 has an opening 381 centrally located in first area 312. Central area 314 has an opening 382 centrally located in central area 314. Second area 316 has an opening 383 centrally located in second area 316. Openings 381, 382, 383 reduce the amount of material used in packing holder 300, which reduces the cost and weight of packing holder 300.

FIG. 7 shows the inner side of packing holder 300 in more detail. In this embodiment, the upper and lower packing holders 300 shown in FIGS. 2-5 are identical. The features of packing holder 300 will be explained using packing holder 300 shown in FIG. 7 as the lower of the two packing holders 300 shown in FIGS. 2-5.

In the example shown in FIG. 7, packing holder 300 generally has three main areas, a first receiving portion 360 at one end of packing holder 300, a second receiving portion 370 at the opposite end of packing holder 300, and a central receiving portion 350 located between first receiving portion 360 and second receiving portion 370.

In this embodiment, packing holder 300 is symmetrical relative to a longitudinal axis extending through first receiving portion 160, central receiving portion 150, and second receiving portion 370. In other embodiments, packing holder 300 is asymmetrical relative to the longitudinal axis.

Shown in FIG. 7 are an end surface 322 and a side surface 340. Side surface 340 includes surfaces 341, 342, 343, 344, 345, 346 and 347. In this example, end surface 322 and side surface 340 are perpendicular to outer surface 310.

In the embodiment shown in FIG. 7, and referring back to FIG. 2, first receiving portion 360 has a plurality of ribs arranged generally around a perimeter of first receiving portion 360 and around opening 381. A plurality of ribs 366 are arranged in a row along a side of first receiving portion 360. Each rib 366 has a groove 367 formed in it to receive an edge of a part of extraction hood 100, in this example an edge of first piece 142 of chimney cover 140. A plurality of ribs 368 are arranged in a row along a side of first receiving portion 360. Each rib 368 has a groove 369 formed in it to receive an edge of a part of extraction hood 100, in this example an edge of first piece 142 of chimney cover 140. Because first piece 142 of chimney cover 140 is L-shaped in this example, two sides of first piece 142 rest in grooves 367 and 369. Second piece 144 of chimney cover 140 is similarly supported by two rows of grooved ribs in first receiving portion 360. A plurality of ribs 362 are arranged in a row along a side of first receiving portion 360. Each rib 362 has a groove 363 formed in it to receive an edge of a part of extraction hood 100, in this example an edge of second piece 144 of chimney cover 140. A plurality of ribs 364 are arranged in a row along a side of first receiving portion 360. Each rib 364 has a groove 365 formed in it to receive an edge of a part of extraction hood 100, in this example an edge of second piece 144 of chimney cover 140. Because second piece 144 of chimney cover 140 is L-shaped in this example, two sides of second piece 144 rest in grooves 363 and 365. Additional grooved ribs are located at the corners of first receiving portion 360. These corner ribs are, in this example, radiused to allow room for chimney cover pieces that have radiused corners as opposed to sharp corners. Space is also provided outside of the corner ribs to allow room for chimney cover pieces that have sharp corners.

In this example, grooves 363, 365, 367, 369 are elevated relative to a floor surface 361 of first receiving portion 360. This is in contrast to the elevation of the groove 375 in second receiving portion 370 (discussed further below). Differing groove elevations provide secure holding of chimney cover parts having different lengths.

In the embodiment shown in FIG. 7, and referring back to FIG. 2, second receiving portion 370 has a plurality of ribs arranged generally around a perimeter of second receiving portion 370 and around opening 383. A plurality of ribs 374 are arranged in four rows along the sides of second receiving portion 370. A groove 375 is formed along the bases of ribs 374 to receive an edge of parts of extraction hood 100, in this example an edge of third piece 146 of chimney cover 140 and an edge of fourth piece 148 of chimney cover 140. Because third piece 146 of chimney cover 140 is L-shaped in this example, two sides of third piece 146 rest in groove 375. Fourth piece 148 of chimney cover 140 is similarly supported by groove 375. Because fourth piece 148 of chimney cover 140 is L-shaped in this example, two sides of fourth piece 148 rest in groove 375. Space is provided in the corners to allow room for chimney cover pieces that either have sharp corners or are radiused.

In this example, groove 375 is bordered by ribs 374 on the outside and a plateau 376 on the inside. In this example, groove 375 is at the same elevation as a floor surface 371 of second receiving portion 370 (see FIG. 13). In this example, the elevation of groove 375 is lower than the elevation of grooves 363, 365, 367, 369 in first receiving portion 360. These differing groove elevations provide secure holding of chimney cover parts having different lengths.

Grooves 363, 365, 367, 369 provide secure holding of two L-shaped pieces in first receiving portion 360. Groove 375 provides secure holding of two L-shaped pieces in second receiving portion 370. The exemplary formation of the various ribs and grooves allow for L-shaped pieces of various leg dimensions (those dimensions along the legs of the “L”) up to the length of the grooves (and the space in the corner areas). This flexibility is advantageous because it allows one size packing holder 300 to be used with various differently sized extraction hoods.

Central receiving portion 350, in this example, is sized to receive chimney frame 150 and transition piece 160. In some embodiments, transition piece 160 fits inside chimney frame 150 and is held in place by chimney frame 150. Because the inside of chimney frame 150 and the outside of transition piece 160 are not seen by the user in the final installation, in some cases these two parts can contact each other without concern over marring their finishes.

FIG. 8 shows is a top view of packing holder 300 and shows outer surface 310 and the relative positions of the various edge surfaces. FIG. 9 is a side view of packing holder 300.

FIG. 10 is a plan view of the inner side of packing holder 300. FIG. 10 compliments FIG. 7 in the view of grooves 363, 365, 367, 369 in first receiving portion 360 and the view of groove 375 in second receiving portion 370.

FIG. 11 is a sectional view along section line XI-XI in FIG. 10 and shows the elevation of grooves 363 and 367 relative to groove 375.

FIG. 12 is a sectional view through first receiving portion 360 along section line XII-XII in FIG. 10 and shows that, in this example, grooves 365 and 369 are at the same elevation.

FIG. 13 is a sectional view through second receiving portion 370 along section line XIII-XIII in FIG. 10 and shows that, in this example, groove 375 is at the same elevation on both sides of opening 383.
