DETAILED DESCRIPTION

FIG. 1 illustrates a shelf system ([0012] 2). The shelf system (2) of the present example comprises two shelves (6), four upright members (4), horizontal supports (16), and a cross-support (10). While FIG. 1 shows four upright members (4), the number and positions of the upright members (4) may be varied based on a variety of factors and preferences known to those skilled in the art.
The shelf ([0013] 6) in the present example includes a planar top surface (12) having a rectangular surface area and front (13), back (23), left (17), and right (35) sides. It will be appreciated that the top surface (12) need not be rectangular. For example, a shelf (6) may be a variety of polygons, including a square, triangle, parallelogram, trapezoid, and the like. In addition to polygons, one or more sides of a shelf (6) may be non-linear, such as convex or concave curves, radii, ellipses, parabolas, and the like. As shown, the top surface (12) has two sides (17, 35) adapted to be installed adjacent to an upright member (4).
In the present example, a front lip ([0014] 14) extends downward from the front side (13) of the top surface (12), and is integrally connected therewith. A back lip (24) extends downward from the back side (23) of the top surface (12), and is integrally connected therewith. A left lip (18) and right lip (36) are integrally connected to the top surface (12), and extend downward from the left side (17) and right side (35) of the top surface (12), respectively. The front lip (14), back lip (24), left lip (18), and right lip (36) each comprise a lip side surface (38) extending downward and generally normal to the planar top surface (12) and a lip bottom surface (26) extending inward and generally normal to the respective lip.
As shown here, the front lip ([0015] 14) extends perpendicularly downward from the front side of the top surface (12). The back lip (24), left lip (18), and/or right lip (36) may extend similarly or differently. For instance, the front lip (14), back lip (24), left lip (18), and/or right lip (36) may extend diagonally downward, curved downward, or in any other downward fashion from the top surface (12). In addition, neither the front lip (14), back lip (24), left lip (18), nor right lip (36) need be substantially planar. The front lip (14), back lip (24), left lip (18), and/or right lip (36) may extend downward for any desired distance, such as, by way of example only, ½″, ¾″, 1″, or any other distance. The height of all of the lips (14, 18, 24, 36) may be made uniform. It is contemplated, however, that a shelf (6) may also be constructed such that the height of one or more lips is different than that of the other lips.
As shown in FIG. 1, the shelf ([0016] 6) in the present example mounts and attaches to upright members (4) of a shelf system (2) at upwardly oriented mounting members (8). In the present example, the mounting members (8) take the form of tabs. Such tabs extend outward and upward from their respective upright member (4). Such tabs are oriented vertically, are flat, and have a rounded end. It will be appreciated by those of ordinary skill in the art that tabs may be configured in many other possible ways as mounting members (8). It will be further appreciated that there are many mounting member (8) alternatives to tabs, such as, by way of example only, lances and prongs and the like, and the shelf (6) may mount to a variety of types of different mounting member (8) configurations. By way of example only, a shelf (6) may also mount to mounting members (8) that are horizontally oriented. In other words, openings (20) in a shelf (6) may receive mounting members (8) that are oriented generally parallel to the top surface (12).
FIG. 1 shows upright members ([0017] 4) having a plurality of mounting members (8) spaced apart equidistantly. However, it will be understood that the mounting members (8) may be arranged in a variety of other configurations. For example, the arrangement of mounting members (8) may differ on each upright member (4), and/or the mounting members (8) may be arranged such that they are not spaced apart equidistantly.
As shown here, the shelf ([0018] 6) engages mounting members (8) at the left lip (18) and the right lip (36). FIGS. 2 and 3 illustrate a method of mounting a shelf (6) to a mounting member (8) on an upright member (4). As shown here, the left lip (18) of a shelf (6) has two pairs of openings (20A, 20B) dimensioned to receive mounting members (8). It is contemplated, however, that more than two pairs of openings (20A, 20B) may be used. Further, instead of a pair of openings (20A, 20B), only a single opening (20A or 20B) may be used. The openings (20A, 20B) shown are aligned vertically, and each opening (20A or 20B) in a pair is the same size as the other opening (20B or 20A) in the pair. Alternatively, one opening (20A or 20B) in a pair may be made larger or smaller than the other opening (20B or 20A) in the pair.
As shown, the openings ([0019] 20A) that are closest to the top surface (12) extend at least in part into the top surface (12). Alternatively, where a shelf (6) is made with at least one lip bottom surface (26), a shelf (6) may have openings (20B) only in the lip bottom surface (26). In other words, a shelf (6) may be made without having any openings (20A) in the top surface (12) and/or lip side surface (38). As further shown, both openings (20A, 20B) in a pair extend at least into part into the lip side surface (38). However, it is contemplated that a shelf. (6) may be made without at least one opening (20A and/or 20B) extending into the lip side surface (38).
By way of example only, each opening ([0020] 20A, 20B) is shown in the form of a slot. The right lip (36) is configured similarly to the configuration of the left lip (18) described above. Alternatively, the right lip (36) may be configured differently from the left lip (18).
The top surface ([0021] 12), front lip (14), back lip (24), left lip (18), and right lip (36) may all be formed from a unitary sheet of metal. For the purposes of this specification and claims, “unitary sheet of metal” means that two or more components share a homogeneous continuum of the same metal. The metal may be, by way of example only, formed from a sheet of aluminum, stainless steel, galvanized steel, powder coated steel, or any other suitable material. The metal may be of any thickness, but preferably between 32 and 12 gauge, more preferably between 24 and 18 gauge, and most preferably about 22 gauge. As illustrated here, the shelf (6) is devoid of any welds.
The shelf ([0022] 6) shown in FIG. 4 further comprises optional strengthening members (22). While FIG. 4 shows two strengthening members (22), it is contemplated that any number of strengthening members (22) may be used. FIG. 4 shows each strengthening member (22) attached to the bottom surface (28) of the shelf (6). The strengthening members (22) may be attached to a surface using a variety of techniques known in the art, including welding, screws, bolts, an adhesive, rivets, TOX® joining by TOX® PRESSOTECHNIK GmbH & Co. KG, and the like.
FIG. 4 shows a strengthening member ([0023] 22) comprised of two flanges (32) and a rib (34) positioned between the two flanges (32). The flanges (32) and rib (34) may be formed from a unitary sheet of metal. Alternatively, any other construction and/or configuration may be used for one or more strengthening members (22). Strengthening members (22) may be comprised of hat channels. FIG. 4 shows the strengthening members (22) positioned such that the strengthening members (22) are parallel to the front side of the top surface (12). One or more optional strengthening members (22) may extend substantially the full length of top surface (12). Alternatively, one or more strengthening members (22) may be positioned or sized in any other suitable way.
FIG. 5 depicts a pre-bent sheet ([0024] 30) that may be formed into a shelf (6), where the dotted lines represent lines along which the pre-bent sheet (30) may be bent or folded to form the shelf (6). The geometry of the pre-bent sheet (30) may be cut from a sheet of metal by stamping, laser cutting, or any other suitable method known in the art. The openings (20A, 20B) are cut in the pre-bent sheet (30) such that one opening (20B) in each pair of openings (20A, 20B) will be positioned at least in part into the respective lip bottom surface (26) and the other opening (20A) in the pair will be positioned at least in part into the respective top surface (12). Both openings (20A, 20B) are cut in the pre-bent sheet (30) such that both openings (20A, 20B) will extend at least in part into the lip side surface of the respective lip (18, 36).
As will be apparent to those of ordinary skill in the art, it is possible that, in forming a lip bottom surface ([0025] 26) on the front lip (14), back lip (24), left lip (18), and/or right lip (36), there may be a tendency for the ends of adjacent lip bottom surfaces (26) to overlap. FIG. 4 shows the lip bottom surface (26) of the front lip (14) and the lip bottom surface (26) of the back lip (24) bent to overlap the lip bottom surface (26) of the right lip (36). The same is shown as to the lip bottom surface (26) of the left lip (18). Alternatively, at least one lip bottom surface (26) may overlap in any other configuration. A shelf (6) may also be constructed such that no lip bottom surfaces (26) overlap at all.
Having shown and described various embodiments of the present invention, further adaptations of the methods and systems described herein can be accomplished by appropriate modifications by one of ordinary skill in the art without departing from the scope of the present invention. Several of such potential alternatives, modifications, and variations have been mentioned, and others will be apparent to those skilled in the art in light of the foregoing teachings. Accordingly, the invention is intended to embrace all such alternatives, modifications and variations as may fall within the spirit and scope of the appended claims and is understood not to be limited to the details of structure and operation shown and described in the specification and drawings.
