DETAILED DESCRIPTION

Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.
FIGS. 1 and 2 illustrate assembled hardwareless shelving systems 10 and 10 a that are well suited to holding objects such as books, CDs, DVDs, and other components commonly placed on shelves. The illustrated shelving system 10, 10 a include two side panels 15, a back panel 20, six shelves 25, and a number of locking keys 30 that when assembled define a shelving unit 10, 10 a with six shelves 25. Of course, other arrangements including more or fewer shelves 25 are envisioned and could be employed depending in the desired shelving application.
All of the components of the shelving systems 10, 10 a of FIGS. 1-2 are formed from plywood or other suitable panel type materials and are assembled without the use of fasteners or hardware such as nails, screws, bolts, glue, adhesives, brackets, and the like. Thus, a single material such as plywood could be employed to build and assemble the complete system 10, 10 a illustrated in FIGS. 1 and 2. The system 10, 10 a described herein are referred to as “hardwareless”. Hardwareless means that the systems 10, 10 a can be assembled using only the building materials used for the structural components. Components such as screws, bolts, nails, brackets, adhesives or any other common fastening device are not needed and are not used.
FIG. 3 illustrates a side panel 15 a similar to the ones employed in the construction of FIGS. 1 and 2 with the only difference being the side panel 15 a of FIG. 3 is sized for a shelving system having only four shelves 25. The side panel 15 a is substantially planar and is formed from plywood or another material having suitable strength and stiffness to support the desired shelves 25. Two feet 35 are formed at the bottom of the side panel 15 a to provide a base for the assembled shelving system. Four shelf slots 40 are formed in the side panel 15 a and extend in a direction normal to a vertical axis 45. Each of the slots 40 is a substantially elongated oval shape with other shapes and arrangements being possible. In the illustrated construction, the shelf slots 40 are equally spaced from one another such that the shelves 25 in the assembled shelving system are equally spaced. However, other constructions could employ uneven spacing if desired.
The side panel 15 a illustrated in FIG. 3 also includes two hook members 50 that are formed as part of the side panel 15 a. Each hook member 50 includes an upward extending portion 55 that cooperates with the remainder of the side panel 15 a to define a slot 60. In the illustrated construction, the slots 60 include a semi-cylindrical bottom surface 65 with other shapes also being possible. The construction illustrated in FIG. 3 includes two hook members 50 with more hook members 50 being possible. In some constructions, a single hook member 50 can also be used on each side. As illustrated in FIG. 3 a, another construction of the side panel 156 extends the bottom portion of the panel 156 from the bottom most hook 50 to the feet 35. This provides additional strength and stability when the shelf system is assembled.
As is best illustrated in FIGS. 1 and 5, the back panel 20 is substantially rectangular and is sized to cover the area behind the shelves 25. The back panel 20 includes a plurality of back hook members 70 that each includes a downward extending portion 75 that cooperates with the remainder of the back panel to define a slot 80. The slot 80 is similar to the slot 60 in the side panels 15 and includes a top surface 85 . The back panel 20 includes the same number of hooks 70 on each side as are included in the side panels 15. Thus, the construction illustrated in FIGS. 1 and 2 includes three hook members 70 on each side of the back panel 20 that are positioned to engage with each of three hook members 50 formed as part of the two side panels 15. In some constructions, the direction of the hooks 50, 70 on the side panels 15 and the back panel 20 are reversed.
In some constructions, the back panel 20 is not required. In these constructions, a diagonal member 300 can be employed rather than using a thicker back portion 20 as illustrated in FIG. 7. The diagonal member 300 includes two hook members 305 that are similar to the hook members 70 of the back panel 20. In some constructions, the diagonal portion 300 is used in conjunction with a back panel to allow for the use of a thinner and lighter back panel 20. In preferred constructions, the diagonal member 300 can be used in place of the back panel 20. These constructions have the added benefit that, when disassembled, the parts can be fit in smaller packaging, thereby facilitating storage and shipping
With reference to FIG. 6, each of the shelf panels 25 is formed from a panel material such as plywood and includes a central shelf portion 90, a first end tongue 95 formed on one end of the shelf and a second end tongue 100 formed on the opposite end of the shelf 25. The first end tongue 95 and the second end tongue 100 are substantially the same to allow the shelf 25 to be installed in either direction.
Each shelf tongue 95, 100 includes a planar portion that is narrower than the central shelf portion 90 such that the central shelf portion 90 defines a shoulder 105. A slot 110 is formed in the tongue portion 95, 100 and includes a first surface 112 that is spaced a first distance 115 from the shoulder 105. The first distance 115 is selected to match or closely match the thickness of the side panels 15 to provide a tight fit as will be discussed below. In the illustrated construction, the slot 110 is an elongated oval with other shapes and arrangements being possible.
With reference to FIG. 4, the locking keys 30 engage the shelf slots 110 to couple the shelves 25 to the side panels 15. Each of the locking keys 30 is substantially mushroom shaped and thus includes a key portion 120 and a head portion 125. The key portion 120 is sized to fit within the shelf slots 110 and the head portion 125 is sized to inhibit the passage of the locking key 30 through the slot 110.
With reference to FIG. 1, the manufacture and assembly of the shelving system 10 will be described. Each of the side panels 15 is first formed with the desired number of hooks 50 and shelf slots 40. The hooks 50 and slots 40 are sized to match the thickness of the panels being used. Thus, if ¾ inch (18 mm) plywood is employed, each of the slots 40 is sized to receive a ¾ inch (18 mm) component. In some constructions, different sized materials are used for the different components. In these constructions, each slot 40 and hook 50 must be sized and positioned for the selected size of the components to which it interfaces.
Each of the shelves 25 is manufactured by forming the tongue portions 95, 100 on each end and by adding the slots 110 in the correct position. Similarly, the back panel 20 is formed with the desired number of hooks 70 positioned as required to engage the side panels 15. Finally, the key portions 30 are manufactured in the quantity required for the particular shelf system being built.
To assemble the shelf system 10, the user first engages the first tongue 95 of the shelves 25 with their corresponding slots 40 in one of the side panels 15. When the shelf 25 is properly positioned, the shoulder 105 will abut the inner surface of the side panel 15 and the first surface 112 of the slot 110 will extend just beyond the outer surface of the side panel 15. One of the key members 30 is then inserted into the slot 110 to couple the shelf 25 and the side panel 15. Next, the user positions the second side panel 15 to engage the second tongues 100 in a manner similar to that described with regard to the first side panel 15. Key members 30 are inserted in the slots 110 of the second tongues 100 to couple the second side panel 15 to the shelves 25 and the first side panel 15. The assembly is completed by engaging the hooks 70 of the back panel 20 with the hooks 50 of the side panels 15.
It should be noted that other constructions of the shelving system could employ elongated key members 30 as illustrated in FIG. 2. The elongated key members 30 a extend through two or more shelves 25 to reduce the total number of components.
FIGS. 9-11 illustrate other arrangements of the shelving system. FIG. 9 illustrates an arrangement 350 of the shelving system that includes multiple shelves at multiple different levels with the different leveled shelves arranged adjacent one another. FIG. 10 illustrates another arrangement 360 of the shelving system that includes only two shelves 365. As can be seen, each shelf 365 includes two tongue portions 95 on each side of the shelf, thereby facilitating a wider shelf 365. As is illustrated in FIG. 10, a single U-shaped key 370 engages both tongue portions 95 to hold the shelves 365 in place. Of course, other key arrangements such as those illustrated herein could be employed if desired. FIG. 11 illustrates an arrangement 380 similar to that of FIG. 9 with the addition of diagonal members 385 similar to that of FIG. 7. The diagonal members 385 provide additional support for the shelf arrangement 380 without using a solid back. In addition, because a large back piece is not employed, the components of the arrangement 380 can be packed into a smaller container, thereby reducing the cost and difficulty of shipping the disassembled components. As one of ordinary skill will realize, many different arrangements of the shelving system can be employed and fall within the scope of the present invention.
Thus, the invention provides, among other things, a shelving system that can be easily manufactured using basic tools and that can be assembled without the use of any hardware or special tools, with preferred constructions needing no tools whatsoever for assembly.
