DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

(12) As required, a detailed embodiment of the present invention is disclosed herein; however, it is to be understood that the disclosed embodiment is merely exemplary of the principles of the invention, which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriately detailed structure.

(13) Referring to FIGS. 2 through 5, the shelf extender 10 includes an upper section 20 and a lower section 30. In some embodiments, the upper 20 and lower 30 sections define relatively consistent cross sections with the cross section of the lower section 30 being somewhat smaller than the cross section of the upper section 20 such that the transition from the upper section 20 to the lower section 30 generally defines a ledge 50. More specifically, the cross section of the upper section 20 of the shelf extender 10 defines approximately the same exterior surfaces as a cross section of a vertical support post 510 of a shelving unit 500 while the cross section of the lower section 30 of the shelf extender 10 defines a profile that is configured to be received within an inner area 515 of the vertical support post.

(14) In use, the lower section 30 of the shelf extender 10 is inserted into the inner area 512 of the vertical support post 510 of an existing shelving unit 500 with the upper section 20 of the shelf extender 10 extending vertically above the vertical support post 510 such that the shelf extender 10 of the present invention is supported by the vertical support post 510 of the shelving unit 500. In some embodiments, the ledge 50 of the shelf extender 10 nests against a top edge 514 of the vertical support post.

(15) The upper 20 and lower 30 sections include respective top 24, 34 and bottom 26, 36 ends. In some embodiments, the bottom end 26 of the upper section 20 is adjacent to the top end 34 of the lower section 30 such that the transition from the upper section 20 to the lower section 30 defines the ledge 50. In some such embodiments, the top end 24 of the upper section 20 is displaced upwardly from the ledge 50 and the bottom end 36 of the lower section 30 is displaced downwardly from the ledge 50.

(16) In some embodiments, such as shown in FIG. 5B, the upper section 20 of the shelf extender 10 defines one or more feature that is configured to assist in utilizing the shelf extender 10 to support signage 600 or the like. In some such embodiments, the feature is a keyhole 22 that is configured to receive a mounting lug 622. In other such embodiments, a plurality of keyholes are strategically positioned between the top 24 and bottom 26 ends of the upper section 20 of the shelf extender 10. It will be appreciated that, in still other embodiments, one or more other features that are well known in the art are utilized instead of, or in addition to, one or more keyhole 22.

(17) In some embodiments, the lower section 30 of the shelf extender 10 defines a channel 32. In some such embodiments, the channel 32 is configured so as to provide clearance within the inner area of the vertical support post for various features used in conjunction with the vertical support post. More particularly, as shown in FIG. 5A, some such embodiments are configured such that when the lower section 30 of the shelf extender 10 is received by a vertical support post 510, the lower section 30 of the shelf extender 10 does not prevent a mounting lug 522, such as a mounting lug 522 of a shelf member 520 of the shelving unit 500, from being received by a keyhole 512 of the vertical support post 510. Furthermore, in some embodiments, the channel 32 is configured such that when a mounting lug 522 is received by a keyhole 512 of a vertical support post 510, the mounting lug 522 does not prevent the lower section 30 of the shelf extender 10 from being received by the vertical support post 510. Furthermore still, in some embodiments, the channel 32 is configured such that when the lower section 30 of the shelf extender 10 is received by a vertical support post 510 and a mounting lug 522 is received by a keyhole 512 of the vertical support post 510, the mounting lug does not prevent the lower section 30 of the shelf extender 10 from being removed from the vertical support post 510 and the lower section 30 of the shelf extender 10 does not prevent the mounting lug 522 from being removed from the keyhole 512. In this way, the shelf extender 10 does not prevent the vertical support post 510 from supporting shelving 520 and shelving 520 does not prevent the vertical support post from supporting the shelf extender 10. It will be appreciated that in various embodiments the mounting lug 522 will be one or more tab, bracket, clip, or any number of one or more other features that are well known in the art for being inserted into keyholes 512 so as to support shelving 520 and/or to otherwise display products.

(18) In some embodiments of the present invention, the shelf extender 10 includes an elongated outer portion 100 that extends from the top end 24 of the upper section 20 to the bottom end 26 of the upper section 20. In some such embodiments, the outer portion 100 includes opposed front 110 and rear 120 panels extending between the top 24 and bottom 26 ends of the upper section 20 and opposed side panels 130 extending between the opposed front 110 and rear 120 panels so as to define an elongated inner area 150. In some such embodiments, a cross section of the outer portion 100 generally defines a rectangular tube.

(19) In some embodiments of the present invention, the shelf extender 10 further includes an elongated inner portion 200 that extends from a bottom end 36 of the lower section 30, past the top end 34 of the lower section 30, towards the top end 24 of the upper section 20. In some such embodiments, the inner portion 200 extends to the top end 24 of the upper section 20. Some embodiments of the inner portion 200 includes opposed side panels 230 (also referred to as side walls 230) extending between the top 140 and bottom 150 ends and a rear panel 220 (also referred to as a rear wall 220) extending between the opposed side panels 230 so as to define a channel 32. In some such embodiments, a cross section of the inner portion 200 generally defines a U-shape.

(20) In some embodiments of the present invention, the inner portion 200 includes an upper portion 202 nested within the inner area 150 of the outer portion 100 and a lower portion 203 extending beyond the outer portion 100 of the shelf extender 10 such that the upper section 20 of the shelf extender 10 comprises the outer portion 100 and the upper portion 202 of the inner portion 200 while the lower section 30 of the shelf extender 10 comprises the lower portion 203 of the inner portion 200.

(21) The present invention further includes various methods of manufacturing a shelf extender 10. One such method includes die-cutting a continuous piece of corrugated material into a design (such as the design shown in FIG. 1) that includes multiple panels that fold against and/or around one another. In some embodiments, the panels are separated by pre-perforated lines for easier folding and assembly. In some such embodiments, the shelf extender 10 is shipped in a flat (knock-down) configuration, for ease of storage and shipping, and then moved to a three-dimensional configuration prior to being used to support signage or the like.

(22) FIG. 1 shows one example of the present invention in a flat configuration laying on a planar surface, such as a table surface. Specifically, the embodiment includes multiple panels separated by perforated lines for easier folding and assembly. The shelf extender 10 is moved to the three-dimensional configuration by first folding a first primary panel 1, a first secondary panel 1a, and a second primary panel 2 up and over until panels 1, 1a, and 2 rest against a fourth primary panel 4, a third secondary panel 3a, and a third primary panel 3, respectively. In the presently described embodiment, there is no second secondary panel 2a (not shown). Panels 2 and 3 are then folded up approximately 90 degrees such that panels 2 and 3 extend generally perpendicularly from the table surface. Next, panels 1a and 3a are folded up approximately 90 degrees such that panels 1a and 2a extend generally perpendicularly from the table surface, thereby moving panels 2 and 3 into a position and orientation that is displaced from and generally parallel with panels 1 and 4. In this way, panels 1, 1a, 2, 3, 3a, and 4, together, define the inner portion 200 of the shelf extender 10, with panels 1a and 3a, together, defining the rear panel 220; and panels 1 and 4, together, and panels 2 and 3, together, defining opposed side panels 230.

(23) After the inner portion 200 of the shelf extender 10 is formed, as discussed above, the remaining panels are then folded/wrapped around the assembly to form the outer portion 100 of the shelf extender 10. Specifically, a fourth secondary panel 4a is folded up approximately 90 degrees such that panel 4a extends between the opposed side panels 230 of the inner portion 200 of the shelf extender 10, followed by a fifth primary panel 5 being folded over panel 3, a fifth secondary panel 5a being folded over panel 3a, a sixth primary panel 6 being folded over panel 4, a sixth secondary panel 6a being folded over panel 4a, a seventh primary panel 7 being folded over panel 5, a seventh secondary panel 7a being folded over panel 5a, and finally an eighth primary panel 8 being folded over panel 6. In this way, panels 4a, 5, 5a, 6, 6a, 7, 7a, and 8, together, define the outer portion 100 of the shelf extender 10 with panels 4a and 6a, together, defining the front panel 110; panels 5 and 7, together, and panels 6 and 8, together, defining opposed side panels 130; and panels 5a and 7a, together, defining the rear panel 120.

(24) In some embodiments, panel 8 includes an adhesive strip 60. In such embodiments, prior to folding panel 8 against panel 6, the backing from the adhesive strip 60 is removed to expose the adhesive. Panel 8 is then adhered to panel 6 using the adhesive and holding the entire assembly together.
