DESCRIPTION OF THE PREFERRED EMBODIMENT

(5) Turning now to the drawings and, more particularly to FIG. 2, a home appliance in the form of a range having an oven and an improved oven rack according to one preferred embodiment of the present invention is illustrated generally at 10. It will be understood by those skilled in the art that the present oven rack assembly finds use in ranges such as the one illustrated in FIG. 2 and built-in ovens, wherein both ranges and built-in ovens may also include steamers that are essentially ovens configured for cooking with steam.

(6) The range 10 includes a generally rectangular range body 12 that may be a freestanding range or a built-in range. The body 12 includes a control panel 14 mounted thereto. An oven cavity 16 is defined in the range body 12 by a plurality of oven walls 18. An oven access opening in the range body 12 is selectively coverable by an oven door 20. It will be appreciated by those skilled in the art that heating elements (not shown) are operationally associated with the oven for use in cooking.

(7) A rack 24 is provided for supporting cooking vessels in the oven cavity 16 and is configured for telescoping movement in and out of the oven cavity 16. In order to more safely and effectively access any cooking vessels carried on the rack 24, the rack 24 is mounted to and moves with traveling gliders 26, 28 along glider support elements 22 mounted to the oven walls 18. The rack 24 and the gliders 26, 28 form a rack assembly. The rack assembly is also illustrated in FIG. 4.

(8) With reference to FIG. 2 and FIG. 4, the gliders 26, 28 are formed with channels for receiving the side portions of the rack 24 as seen in FIG. 2. The gliders 26, 28 facilitate dependable and stable movement of the rack 24 into and out of the oven cavity 16. The direction of rack 24 movement is indicated by an arrow A in FIG. 4.

(9) In order to provide smooth movement and a rigid surface, the present rack 24 has substantial dimensional stability. A dimensionally stable rack should not warp or otherwise strain to bend which could jeopardize the integrity of its mount or urge the traveling gliders into a bind. During manufacture, such dimensional stability can make certain manufacturing steps more straightforward and efficient.

(10) The present rack is illustrated in FIG. 3 without the traveling gliders 26, 28. While the present rack 24 is configured for mating with the same gliders as the prior art rack of FIG. 1, it should be understood that there are no particular requirements of the gliders other than to support the rack 24 in a stable and sufficiently strong manner.

(11) The rack 24 includes a wire grid fabricated from metal rods extending intermediate two planar side panels 50, 52. The wire grid does not include a perimeter rail and includes no significant bends and no wire side rails. Each side panel 50, 52 includes a generally planar rectangular slab-like, upstanding side body 54 that is formed as a generally flat, thin planar member having a flat outer surface 56 and a flat inner surface 58. The side panels 50, 52 are devoid of overhangs, flanges and the like and define the forwardmost and rearwardmost extent of the rack 24.

(12) Throughbores or holes 60, 62 are formed through each side body 54 for accommodating mounting lugs or bolts from the gliders. It should be understood that the holes 60, 62 may be formed through the side panels 50, 52 in whatever configuration or position required to accommodate the glider of choice. Each side panel 50, 52 includes thin edges separating the inner surface 58 and the outer surface 56. The edges include a top edge 64, a bottom edge 66, and two end edges 68.

(13) The cooking vessel support surface grid is fabricated from a plurality of lateral rails including a front lateral rail 30 and a rear lateral rail 32 extending as straight cross members between the side panels 50, 52. Both the front later rail 30 and the rear later rail 32 are fixed to the side panels 50, 52 at each end thereof and spaced slightly inwardly from the end edges 68. A raised rear lateral rail 34 extends from one connection point on the rear lateral rail 32 to another intermediate the two side panels 50, 52 and is spaced inwardly from the junction of the rear lateral rail 32 and the side panels 50, 52. A pair of intermediate lateral rails 44 extend as straight cross members between the side panels, 50, 52. All of the lateral rails 30, 32 44 are fixed to the side panels 50, 52 at respective welds 70. While FIG. 3 illustrates two intermediate lateral rails, there could be more depending on design factors.

(14) A plurality of parallelly extending longitudinal rails 36 are mounted to the front lateral rail 30 and the rear lateral rail 32 to extend therebetween as support members and form a portion of the cooking vessel support surface grid. The longitudinal rails 36 are attached by welds 40 at the rear lateral rail 32 and are fixed to the front lateral rail 30 at respective welds 38. The longitudinal rails 36 are formed with curved hooks to remove any sharp or rough edges from the chance of user contact.

(15) A short intermediate lateral rail 46 extends as a straight cross member between the longitudinal rails 36 but does not engage either side panel 50, 52. Further, short longitudinal rails 42 extend from the short lateral rail 46 to the rear lateral rail 32. The short lateral rails 46 are intermediate two groups of four longitudinal rails 36 that together define a handle space 48 to accommodate access by a user to facilitate manually extending the rack from the oven and inserting the rack into the oven cavity.

(16) FIG. 4 illustrates the rack 24 mounted to the gliders 26, 28 with the side panels 50, 52 mounted to the channels of each glider 26, 28 to form a rack assembly. The mounting is accomplished using the holes in the side panels 50, 52 in conjunction with a nut-and-bolt arrangement associated with the gliders 26, 28. Mounting elements 72 are provided that mount to the glider supports 22, seen in FIG. 2.

(17) By the above, the present invention provides a home appliance and an oven rack assembly that reduces the cost of manufacture and enhances dimensional stability by eliminating repeated bends, welds, flattening steps and the perimeter wire form. The rack assembly of the present invention provides a more simplified construction and effectively enhances manufacturing efficiency while reducing the overall cost of the associated appliance. The rack itself requires less-intensive manufacturing steps and should also provide a lower cost as a spare part.

(18) It will therefore be readily understood by those persons skilled in the art that the present invention is susceptible of a broad utility and application. While the present invention is described in all currently foreseeable embodiments, there may be other, unforeseeable embodiments and adaptations of the present invention, as well as variations, modifications and equivalent arrangements, that do not depart from the substance or scope of the present invention. The foregoing disclosure is not intended or to be construed to limit the present invention or otherwise to exclude such other embodiments, adaptations, variations, modifications and equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof.
