## Background
BACKGROUND OF THE INVENTION
This application claims priority from U.S. Provisional Application Ser. No. 60/554,517, filed on Mar. 19, 2004.


The present invention is directed to a wall cabinet system, and more particularly to a bracket for interconnecting the side panels and shelves of a wall cabinet system.
Wall cabinet systems are well known as an aesthetically pleasing way to organize household items. These systems generally include four outer panels that are connected together to contain an organizing unit, such as a set of drawers, a shelving unit, or a stack of storage baskets. In order to provide a tidy appearance, the system is mounted to a wall a desired distance off of the floor.
In many cases, the organizing unit of a single wall cabinet system may be sectioned into a number of smaller units. For instance, a shelving unit may be stacked on top of a drawer unit to provide the consumer with options for organizing items.
Difficulties arise in the packaging of wall cabinet systems for sale to consumers, because many retailers limit the size and weight of any single container. These limits typically prevent large wall cabinet systems from being packaged in one piece, and in many cases they require dividing the outer panels into more manageable sizes. These limitations provide advantages for consumers, because the smaller units, such as a shelving unit and a drawer unit, can be sold separately. Each individual unit simply includes a pair of side panels, a top shelf forming an upper surface of the unit, and a bottom shelf forming a lower surface of the unit. Consumers can buy only the units that they want, and then connect them together as desired. Manufacturers must provide a means for connecting the individual units together. The connection means must add only a minimal cost for manufacturers, while making the connection of units as easy as possible for consumers.
SUMMARY OF THE INVENTION
The present invention is directed to a wall cabinet connection system including separate wall cabinet units to be easily and securely interconnected. In one embodiment, the present invention includes a bracket and a plurality of fasteners for connecting first and second side panels and first and second shelves. The bracket includes a plurality of fastener receiving holes. A first fastener extends through an upper side panel and a first fastener receiving hole; a second fastener extends through the lower side panel and a second fastener receiving hole; a third fastener extends through the upper side panel, a third fastener receiving hole, and the upper shelf; and a fourth fastener extends through the lower side panel, a fourth fastener receiving hole, and the lower shelf.
In a more specific embodiment, the bracket is a plate that includes a pair of inner holes and a pair of outer holes. The bracket is positioned against the side panels, with at least one inner hole and at least one outer hole overlapping the first side panel, and at least one inner hole and one outer hole overlapping the second side panel. The shelves each include a first side edge that abuts the bracket. The side edge of the upper shelf is aligned with the inner hole that overlaps the first side panel. The side edge of the second shelf is aligned with the inner hole that overlaps the lower side panel.
The present invention also includes a method for connecting first and second side panels and first and second shelves of wall cabinet system, comprising the steps of (a) placing a bracket against the first and second side panels, such that a portion of the bracket overlaps the first side panel and a portion of the bracket overlaps the second side panel; (b) abutting each of the first and second shelves against the bracket opposite the first and second side panels; (c) inserting a first fastener through the first side panel and into a first hole in the bracket; (d) inserting a second fastener through the second side panel and into a second hole in the bracket; (e) inserting a third fastener through the first side panel, a third hole in the bracket, and into the first shelf; and (f) inserting a fourth fastener through the second side panel, a fourth hole in the bracket, and into the second shelf.

DETAILED DESCRIPTION OF THE CURRENT EMBODIMENT
A wall cabinet system according to one embodiment of the present invention is shown in FIG. 1 and generally designated 10. In general, the wall cabinet system 10 is comprised of a number of upper side panels 20, lower side panels 22, and a number of shelves 24 and 26. An upper 20 and lower 22 side panel, and first 24 and second 26 shelves are interconnected by one or more brackets 30 and a plurality of fasteners 40.
As shown in FIG. 1, the wall cabinet system 10 is comprised of four individual wall cabinet units, including two upper units and two lower units. The upper units include a cabinet unit 12, a drawer unit 14, a shelving unit 16, and a storage basket unit 18. Notwithstanding the variety of units available, each unit generally includes a pair of side panels 20 or 22, a first shelf 24 forming an upper surface of the unit, and a second shelf 26 forming a lower surface of the unit. A wall cabinet system 10 is formed by connecting two or more of these individual units together. The entire wall cabinet system 10 may be mounted on a wall by a conventional mounting method, such as a plurality of hooks extending from the rear surface 32 of the system 10 that hang on brackets (not shown) attached to the wall. When the system 10 is mounted on a wall, the second shelves 26 of any lower units are spaced above the floor. Alternatively, the system 10 may not be hung from a wall and may rest on the floor. Individual units may be arranged and connected together as desired by the consumer. The bracket 30, as described below, is typically used to connect an upper unit (such as units 12 and 16 in FIG. 1) to a lower unit (such as units 14 and 18 in FIG. 1) disposed directly below the upper unit. Alternatively, the bracket 30 may be used to connect side-by-side units, for instance, in a configuration where the side panels 20 and 22 and shelves 24 and 26 are rotated 90 degrees and mounted on a wall.
Referring now to FIGS. 2 and 3, the side panels 20 and 22 each include an upper surface 46, a lower surface, 48, and opposing front and rear surfaces 50 and 52. The side panels 20 and 22 may be comprised of a wide variety of materials, and may have a variety of shapes and sizes. In addition, the side panels may each include a plurality of fastener receiving holes 56 that extend through the front and rear surfaces 50 and 52. The shelves 24 and 26 each include opposing side edges 60 and 62, a top surface 64, and a bottom surface 66. The side edges 60 and 62 may include a number of pre-drilled, fastener receiving holes 68.
As shown in FIG. 4, the bracket 30 is typically a flat plate with opposing front 31 and back 33 surfaces, however, it may be L-shaped, U-shaped, or a wide variety of alternative shapes. It may be comprised of a variety of materials, such as metal or plastic. The bracket 30 includes a plurality of fastener receiving holes. In the illustrated embodiment, the bracket includes a pair of outer holes 34 and 36, and a pair of inner holes 38 and 42. The holes may be aligned in a row as illustrated, but this is not necessary. One outer hole 34 and one inner hole 38 are positioned in an upper portion 70 of the bracket 30, and the other outer hole 36 and inner hole 42 are positioned in a lower portion 72 of the bracket 30. As shown, the outer holes 34 and 36 are slightly larger than the inner holes 38 and 42. The holes may otherwise all have the same size, or may each have different sizes. In an alternative embodiment, the bracket 30 may be a flat plate without any holes, and may be comprised of a material for receiving self-tapping fasteners. The fasteners 40 are typically conventional, such as screws. The fasteners 40 may all be the same size and length, or they may be of varying lengths. As shown, the two inner fasteners 80 are longer than the two outer fasteners 82.
As shown in FIGS. 2 and 3, when connecting an upper wall cabinet unit to a lower wall cabinet unit, an upper side panel 20 (forming part of the upper wall cabinet unit) and a lower side panel 22 (forming part of a lower wall cabinet unit) are positioned such that the bottom edge 48 of the upper side panel 20 abuts the top edge 46 of the lower side panel 22. The bracket 30 is positioned against the inner surface 50 of the side panels 20 and 22, such that the upper portion 70 of the bracket 30 overlaps the upper side panel 20 and the lower portion 72 of the bracket overlaps the lower side panel 22. A first shelf 24 (forming part of the lower wall cabinet unit) and a second shelf 26 (forming part of the upper wall cabinet unit) are positioned perpendicular to the side panels 20, 22 with a side edge 62 of each shelf abutting the bracket 30. The shelves 24, 26 are further positioned such that the side edge 62 of the first shelf 24 is aligned with the inner hole 42 on the lower portion 72 of the bracket and the side edge 62 of the second shelf 26 is aligned with the inner hole 38 on the upper portion 70 of the bracket 30. As illustrated in FIGS. 2 and 3, there is a slight gap between the shelves 24, 26 in this position; however, the shelves 24, 26 may contact each other.
Once the side panels 20, 22, shelves 24, 26, and bracket 30 are positioned, they are secured into place with the fasteners 40. A first fastener extends through the upper side panel 22 and the outer hole 34 in the upper portion 70 of the bracket 30. A second fastener extends through the upper side panel 22, the inner hole 38 on the upper portion 70 of the bracket 30 and into the edge 62 of the second shelf 26. A third fastener extends through the lower side panel 22, the inner hole 42 on the lower portion 72 of the bracket 30, and into the edge 62 of the first shelf 24. A fourth fastener extends through the lower side panel 22 and the outer hole 36 in the lower portion 72 of the bracket 30. A second set of side panels 20, 22 may be connected to the side edges 64 of the shelves 24, 26 in the same manner. In the illustrated embodiment, two brackets are used for interconnecting each pair of side panels to one side of the shelves. While the illustrated embodiment shows only four fasteners and for fastener receiving holes in the bracket 30, additional fasteners and holes may be used, for instance, by using two fasteners at each of the four positions for additional strength.
The above descriptions are those of a current embodiment of the invention. Various alterations and changes can be made without departing from the spirit and broader aspects of the invention, which are to be interpreted in accordance with the principles of patent law including the Doctrine of Equivalents.
