A first support arm extends along the left edge of the support surface and a second support arm extends along the right edge of the support surface. The first and second support arms are each connected by a substantially right angle bend to the support surface. The first and second support arms each extend rearwardly beyond the rear edge of the support surface. The support surface and the support arms are formed from a single piece of metal and are bent into a final configuration without the use of fasteners to join or hold separate parts or components together.
- In an embodiment, the support surface includes a plurality of openings formed therein. For example, the plurality of openings may be a series of parallel slots extending generally front to rear. In one embodiment, the series of parallel slots may be two rows of parallel slots. In any configuration of openings, the openings may include downwardly depending walls which define the openings.
- In an embodiment, the support arms each are provided with hooked tabs arranged to engage with a support ladder in the refrigerator.
- In an embodiment, the support surface includes a raised rim extending around a perimeter of the surface.
- In an embodiment, a downwardly extending lip may be formed at the front edge of the support surface.

FIG. 1 illustrates arefrigeration appliance 20 having acabinet 22 with adoor 24 openable to expose arefrigeration compartment 26. Other refrigeration appliances, such as some located in stores, do not have doors that need to be opened to expose the refrigeration compartment. Positioned within therefrigeration compartment 26 are a number ofshelves 28, one or more of which may embody the principles of the present invention. In the illustrated embodiment, theshelves 28 are supported byslotted ladders 30 at therear wall 32 of therefrigeration compartment 26 in a known cantilevered fashion. - The
shelves 28 are shown in greater detail inFIGS. 2-6 , where it is seen that each shelf has a generally flat,horizontal support surface 34 comprising aleft edge 36, aright edge 38, afront edge 40 and arear edge 42. Afirst support arm 44 extends along and depends from theleft edge 36 of thesupport surface 34 and asecond support arm 46 extends along and depends from theright edge 38 of the support surface. The first 44 and second 46 support arms are each connected by a substantiallyright angle bend support surface 34 so that they each reside generally in a vertical plane. The first 44 and second 46 support arms each extend rearwardly and may extend beyond therear edge 42 of thesupport surface 34. Thesupport surface 34 and thesupport arms single piece shelf 28 may be securely held in its folded final configuration or strengthened by a securing or strengthening element, such as by a metal clinch between two overlapping sections of the single piece shelf, or by a tack weld between two overlapping sections. Separate pieces are not required to be gripped and held in a predefined orientation relative to one another, rather the folded single piece must merely be retained in its folded condition temporarily while the securing or strengthening element is applied. In a progressive die press, the securing or strengthening element may be applied as an automated additional step without adding further complexity to the manufacturing process. - In an embodiment, the
support surface 34 includes a plurality ofopenings 52 formed therein. For example, as shown inFIGS. 2 and 3 , the plurality ofopenings 52 may be a series of parallel slots extending generally front to rear. In one embodiment, as shown, the series of parallel slots may be two rows of parallel slots in which the slots are formed as elongated ovals. In other embodiments, the slots may have other configurations, such as extending side-to-side rather than front-to-rear, and may be arranged in chevron configurations or other non-linear configurations. Theopenings 52 themselves may also be formed with a configuration different than the illustrated oval slot, and could include round, square, rectangular, pentagonal or other polygonal shapes and combinations of curved and straight edges. - In any configuration of openings, as shown in greater detail in
FIG. 4 , theopenings 52 may include downwardly dependingwalls 54 which define the openings. The downwardly dependingwalls 54 provide additional strength to thesupport surface 34. Alower edge 55 of thewalls 54 may be curled over to avoid sharp edges of the wall. - In an embodiment, the
support arms tabs 56 extending rearwardly of therear edge 42 of thesupport surface 34 and are arranged to engage with thesupport ladders 30 in therefrigeration appliance 20. Thetabs 56 engage in the slots of theladders 30 and arear edge 58 of thesupport arms shelf 28 in a cantilevered fashion. - To provide additional strengthening for the
shelf 28, in an embodiment, thesupport surface 34 includes a raisedrim 60 extending around aperimeter 62 of the surface. The raisedrim 60 is comprised of a shortvertical wall segment 64 and a horizontal wall segment 66. - In an embodiment, a downwardly extending
lip 68 may be formed at thefront edge 40 of thesupport surface 34 orrim 60. Thislip 68 extends across the entirefront edge 40 and abuts the twosupport arms front lip 68 andsupport arms - In an embodiment, an upwardly positioned
ledge 70 may be formed by arear edge riser 72 at therear edge 42 of thesupport surface 34 orrim 60. Theledge 70 may extend across the entirerear edge 42 of thesupport surface 34 and a portion of thesupport arms hooked tab 56 may extend rearwardly from thesupport arms ledge 70. - To provide further strengthening for the
shelf 28, one or more ribs orchannels 74 may be provided in eachsupport arm - The
shelf 28, as described can be formed through a series of bends, draws and punches, and with the various strengthening bends and walls described allows the shelf to be formed from a thinner metal material than is presently used for refrigerator shelf construction. For example, presently used shelves have a thickness of about 0.060-0.070 inches, and the shelves made in accordance with the principles of the present invention may be formed of steel having a thickness of about 0.030 inches. In order to assure support strength for the attachment of theshelf 28 to thesupport ladder 30, the metal material forming the shelf may be folded over to provide a double thickness in the area of the tabs 56 (as best seen inFIG. 5 ), either by folding the material up from a lower edge of thetabs 56 or folding the material back from a rear edge of the tabs. If theshelf 28 is formed from a material having sufficient thickness or strength, the folding over would not be necessary. - To form the
shelf 28 of the present invention, a single flat sheet of metal, such as cold rolled commercial quality steel, drawn quality cold rolled steel or stainless steel (300 series), may be sequentially operated on in a progressive die press in which various of theopenings 52 are formed, the outer perimeter shape is defined by cutting or punching, the various bends and draws are made and thus the shelf is completed from a single flat sheet to the finished configuration by mechanical shaping, all without further assembly or use of fasteners including welding of separate components or parts. Tack welding or clinching of the folded or bent portions of the single piece shelf can occur, for strengthening or securing purposes, during the operation of the progressive die press, without the gripping or positioning of additional components or parts. - The resulting
unitary self 28 has the required structural strength while being very economical to manufacture. Following the formation of theshelf 28 in the press, the shelf may be coated with powder coating, high solids coating, or electro-coating paint systems and may be pointed a variety of colors and/or may carry a variety of decorative hot stamps or films. - As is apparent from the foregoing specification, the invention is susceptible of being embodied with various alterations and modifications which may differ particularly from those that have been described in the preceding specification and description. It should be understood that we wish to embody within the scope of the patent warranted hereon all such modifications as reasonably and properly come within the scope of our contribution to the art.
