BACKGROUND OF THE INVENTION
Various types of shelf systems have been developed for storing items. Known shelf systems may include cantilevered supports that engage vertical rails to support the shelves. Other shelves are configured to be supported between vertical wall surfaces on pins or other supports. However, known shelving systems may suffer from various drawbacks.
SUMMARY OF THE INVENTION
One aspect of the present invention is a shelf having a relatively thin front edge with a very small vertical dimension. The thin front edge causes the shelf to appear as if it has little or no thickness when viewed from a normal range in front/above the shelf.
The shelf includes opposite end portions that are configured to engage pins or other supports disposed on spaced apart vertical support surfaces to thereby support the shelf. The shelf includes a metal shelf structure having a generally tubular construction including an upper sheet portion having a generally planar horizontal portion defining front and rear edges. The shelf structure further includes a lower sheet portion and front and rear portions that interconnect the upper and lower sheet portions to define an interior space. The opposite end portions of the shelf structure extend between front and rear corners of the shelf. Each end portion of the shelf includes front and rear support features that are configured to engage horizontal pins or other supports extending from vertical support surfaces adjacent the opposite end portions of the shelf structure to support the shelf structure adjacent the front and rear corners thereof. The lower sheet portion of the metal shelf structure includes a generally planar horizontal rear portion that is spaced apart from the planar horizontal upper sheet portion to define a substantially uniform vertical first dimension. The lower sheet portion further includes a generally planar angled front portion that intersects the rear portion along an intersection or fold line. The angled front portion extends forwardly and upwardly from the rear portion to the front portion of the shelf structure. A front portion of the shelf structure thereby tapers to provide a significantly reduced vertical dimension at the front edge portion of the shelf structure relative to the vertical first dimension.
Another aspect of the present invention is a shelf having opposite end portions that are configured to engage spaced apart vertical supports to thereby support the shelf. The shelf includes a generally planar top panel having a front edge, a rear edge, and side edges extending between the front and rear edges. The shelf also includes a bottom panel having a generally planar rear portion that is vertically spaced apart from the top panel to define a first vertical dimension. The bottom panel further includes a generally planar angled front portion that extends forwardly and upwardly from the rear portion. The angled front portion is joined to the top panel along the front edge thereof to define a front shelf edge having a second vertical dimension that is substantially smaller than the first vertical dimension. Each opposite end of the shelf includes at least two downwardly facing support surfaces that are open outwardly away from the opposite end portions to receive support members such as horizontal pins extending from the vertical supports.
Another aspect of the present invention is a storage system including a pair of spaced apart upright panels having generally vertical inner sides that face one another. At least two supports extend inwardly from each vertical inner side of the upright panels. The storage system further includes a shelf having front and rear edges and opposite ends engaging the supports to support the shelf. The shelf includes a planar horizontal upper surface and a lower surface having a planar horizontal rear portion and an angled forward portion that extends forwardly and upwardly from the planar horizontal rear portion such that the shelf has a reduced thickness along the front edge of the planar horizontal upper surface.
Another aspect of the present invention is the ornamental design for a shelf as shown and described in the drawings.
These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.

DETAILED DESCRIPTION
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG. 1. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.
The left-hand side elevational views are mirror images of the left-hand side elevational views of FIGS. 8, 15, 22, and 28.
With reference to FIGS. 1 and 2, a shelf system 1 according to the present invention includes one or more shelves 2 having opposite ends 4A, 4B that engage pins 18 disposed on upright members 6. The upright members 6 may comprise panels or other structures having vertical inner surfaces 8. The inner surfaces 8 of upright members 6 may include vertical rows of openings 16 that receive supports such as pins 18 to support the shelves 2. The upright members 6 may be interconnected by an upper panel 10, rear panel 12 and a lower panel 14 to define a cabinet structure. However, it will be understood that the upright members 6 could comprise architectural walls, partition panels, or other vertical support structures of the type that include pins 18 or other suitable supports.
With further reference to FIG. 3, each shelf 2 may include an upper member 20 and a lower member 22. The upper and lower members 20 and 22 may comprise two separate pieces of sheet metal such as mild steel or other suitable material that are welded together, or the upper and lower members may comprise a single piece of material that is extruded, roll-formed, molded, or otherwise formed from metal, polymer, or other suitable material. The upper member 20 includes a generally planar upper portion 24, opposite side edges 26A and 26B, a front edge 28, and a rear edge 30. The upper member 20 also includes a downwardly extending rear flange 32 and a downwardly extending front flange 34.
The lower member 22 includes opposite side edges 36A and 36B, a front edge 38, and a rear edge 40. The lower member 22 also includes a generally planar rear portion 42 and an angled front portion 44 that is joined with the planar rear portion 42 along a fold line or intersection 46. The angled front portion 44 extends upwardly and forwardly such that a front portion 48 (see also FIG. 4) of the shelf 2 has a reduced vertical dimension relative to a rear portion 50 of the shelf 2. Lower member 22 also includes a rear flange 52 that extends upwardly, and an edge flange 54 that extends horizontally from the rear flange 52. When assembled, the edge flange 54 may be spot welded to the upper member 20 to form a rear channel 96 (FIG. 5).
With further reference to FIG. 4, the lower member 22 includes a horizontal front portion 56 having an upper surface 58 that abuts a lower surface 60 (see also FIG. 3) of upper member 20 when upper and lower members 20 and 22 are assembled. The horizontal portion 56 of lower member 22 may be spot welded to upper member 20 such that the shelf 2 has a generally tubular construction defining an interior space 62 (FIG. 5). The opposite ends 4A and 4B of the shelves 2 are preferably open. However, the ends 4A and 4B may be closed off by flanges (not shown) formed from upper member 20 or lower member 22. Alternatively, end caps or covers (not shown) may also be utilized to close off the ends 4A and 4B of the shelves 2.
Referring again to FIG. 4, lower member 22 further includes a front edge flange 64 that extends downwardly and forwardly from the horizontal portion 56. Front edge 66 of flange 64 is disposed directly adjacent and behind lower edge 68 of downwardly extending front flange 34 of upper member 20. A front portion 44A of angled portion 44 of lower member 22, horizontal portion 56 of lower member 22, and front edge flange 64 of lower member 22 together define a downwardly opening shallow channel 70 that extends along front edge 72 of shelf 2.
With further reference to FIG. 5, flange 34 defines a substantially planar vertical front surface 74. The planar upper surface 24 of upper member 20 and the planar rear surface 42 of lower member 22 are spaced apart to define a vertical dimension “D1.” The front surface 74 defines a second vertical dimension “D2” that is significantly less than the first vertical dimension D1. In a preferred embodiment, the first vertical dimension D1 is about 0.75 inches, and the second vertical dimension D2 is about 0.16 inches. However, the shelf 2 may have other dimensions as required for a particular application. In general, the first dimension D1 is at least about twice as great as second dimension D2 (i.e. the second dimension D2 is preferably no greater than one half of the first dimension D1). More preferably, the vertical dimension D1 is at least about three times the second vertical dimension D2. However, the ratio of the first vertical dimension D1 to the second vertical dimension D2 may be substantially greater than 3 according to other aspects of the present invention. Also, it will be understood that the first vertical dimension D1 may be larger than 0.75 inches (e.g. 1.0 inches or larger), or the first vertical dimension D1 may be less than 0.75 inches (e.g. 0.50 inches or less).
Referring again to FIG. 5, the shelf 2 may have an overall depth “W” of about 14 or 15 inches. However, the depth W may be significantly larger or smaller than 14 or 15 inches. The distance “W1” between the rear flange 32 of shelf 2 and the intersection 46 between the planar rear portion 42 and angled front portion 44 of lower member 22 is preferably about two-thirds of the overall depth W. Thus, the ratio W1/W2 is preferably about 2.0. However, the ratio of W1/W2 may be significantly greater than 2.0, or the ratio may be significantly less than 2.0. In general, the dimension W2 is preferably at least about 2.0 inches, and more preferably at least about 4.0 inches. In a preferred embodiment, W2 is equal to about 5.5 inches. In general, a large dimension W2 will provide a thinner appearance which may be desirable. However, larger dimensions W2 may reduce the strength of shelf 2 along the front edge 28. The overall length “L” (FIG. 3) of the shelves 2 will vary as required, and is, in general, somewhat smaller than the internal dimensions between upright members 6.
The preferred dimensional characteristics to provide a visually thin appearance may also be defined utilizing a ratio of thickness to depth dimension W2. Specifically, the difference between D1 and D2 (i.e. D1−D2) divided by W2 is preferably about 1/10 (0.10) (i.e. (D1−D2)/W2= 1/10). The ratio of D1−D2 to W2 (i.e. (D1−D2)/W2) is preferably in a range of about 1/12 to about ⅛. Thus, shelf 2 is preferably configured such that:
Although shelf 2 could be configured such that the dimensions D1, D2, and W2 do not satisfy the relationship specified in equation 1.0, shelf 2 is preferably configured to satisfy the relationship defined in equation 1.0 to provide a visually thin appearance.
Referring again to FIG. 3, shelf 2 may include an elongated reinforcing member 76. The reinforcing member 76 may comprise a hat channel having a generally planar horizontal upper web 78, vertical webs 80 and 82, and horizontal flanges 84 and 86. The flanges 84 and 86 may be spot welded to the lower member 22. Flange 86 is preferably positioned directly adjacent fold line or intersection 46. Hat channel 76 is preferably positioned as close to front edge 28 of shelf 2 as possible to provide increased bending strength along the front edge of shelf 2. When assembled, the upper surface 88 of horizontal upper web 78 is disposed directly adjacent (or abutting) lower surface 60 (see also FIG. 5) of upper member 20. The upper member 22 is preferably not welded to the reinforcing member 76 to avoid creating irregularities in the planar upper surface 24 of upper member 20. The reinforcing member 76 provides bending strength and stiffness to reduce bending of shelf 2 that could otherwise occur. Furthermore, the stiffness provided by the reinforcing member 76 permits the vertical dimension D1 (FIG. 5) to be minimized, thereby providing a shelf 2 having a relatively thin profile.
With further reference to FIG. 4, the opposite side edges 36A and 36B of lower member 22 may include cut out portions 92 that receive pins 18 when shelves 2 are installed between upright members 6. A flange 94 extends upwardly to provide a stop that engages pin 18 to prevent forward movement of shelf 2 unless the shelf 2 is lifted upwardly to disengage pin 18 from cut out area 92. When shelves 2 are supported on pins 18, the pins 18 contact lower surface 90 of upper member 20. The cut outs 92 form recesses or pockets that receive the pins 18 to reduce the visibility of the pins 18.
Referring again to FIG. 5, the flanges 52 and 54 of lower member 22, and the rear flange 32 of upper member 20 together define a rear channel 96 that opens downwardly. When shelf 2 is positioned on pins 18, a pair of the pins 18 contact lower surface 98 of flange 54 in rear channels 96 to thereby support a rear portion 100 of the shelf 2. The vertical position of the lower surface 54 relative to the planar upper surface 24 of upper member 20 is substantially the same as the lower surface 60 of upper member 20, such that the pins 18 support the shelves 2 in a substantially horizontal manner.
It is also to be understood that variations and modifications can be made on the aforementioned structures and methods without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
