Abstract
A modular shelving system has a first wall and a second wall. Extending between the first wall and the second wall is a plurality of rigid bridging members. Each of the walls has a base panel and a detachably connected ancillary panel. An upper profile of the base panel and a lower profile of the ancillary panel vertically interlock to form an interface. A plurality of apertures is formed along the interface when the panels are interlocked. A fastener, such as a screw, can be inserted through each of the plurality of apertures to detachably connect one of the walls to one of the plurality of bridging members. Additional walls and bridging members may be provided to form additional storage modules. Each wall may also be heightened by adding ancillary panels to form a highly accommodating expandable shelving system.
Description




BACKGROUND OF THE INVENTION




1. Technical Field




The present invention is directed to a shelving system and in particular, to a modular shelving system capable of being readily assembled and disassembled.




2. Description of Related Art




Various types of modular shelving systems have been disclosed to the public for storing articles. Many modular shelving systems have stackable modular units. Examples of stackable shelving systems are shown in U.S. Pat. Nos. 5,421,467; 5,788,088 and 5,791,265. U.S. Pat. No. 5,421,467 describes stackable modular units each having first and second support members in parallel to one another with a continuously positionable shelf The modular units may be stacked wherein mating upper and lower stacking surfaces of the support members abut. U.S. Pat. No. 5,788,088 also describes a stackable rack. The tower-like rack described in U.S. Pat. No. 5,788,088 has a base body, three columns, and a plurality of support plates for individually supporting compact disk boxes. Yet another stackable shelving system is described in U.S. Pat. No. 5,791,265. The shelving system in U.S. Pat. No. 5,791,265 includes open-sided frames stacked together to form columns. The columns have a guide opening which receives a shelving element thereby locking the stacked frames together.




In addition to generally stackable shelving systems, other shelving systems can be extended laterally as well as vertically. Typically, extendable modular units are connected or repeated in the direction of shelving support members. An example of a modular extendable shelving system is shown in U.S. Pat. No. 5,695,081 where the system comprises interconnecting vertical posts, horizontal beams, side horizontal braces, coupling connectors, and horizontal shelf pieces positioned on the horizontal beams.




U.S. Pat. No. 5,279,232 describes another extendable shelving assembly having two substantially upright side panels each having holes through their surfaces. Shelf-support members extend between the side panels. The shelving assembly can be repeated in the direction of the shelf-support members for the entire length of a wall.




U.S. Pat. No. 5,722,544 shows yet another extendable shelving system including modular base units connected with binder clips. Each modular base unit further has at least two shelving units interconnected with vertical support posts.




There is still a need, however, for a modular shelving system that is easy to assemble and expandable in both the vertical and horizontal directions. There is also a need for a modular shelving system that is readily assembled yet securely connected so as to prevent displacement between its components.




SUMMARY OF THE INVENTION




A modular shelving assembly is provided and includes a substantially vertical first wall; a second wall parallel to the first wall wherein each of the first wall and the second wall has a base panel and an ancillary panel. The base panel comprises an upper profile and the ancillary panel comprises a lower profile adapted to vertically interlock with the upper profile of the base panel. An interface and a plurality of apertures is formed where the upper and lower profiles interlock. The shelving system further has at least one bridging member. The bridging member extends between the first wall and the second wall and can be detachably connected to the first wall with a fastener extending through one of the plurality of apertures.




The modular shelving system may further be expanded along the length of a wall by adding additional walls interconnected with additional bridging members. The modular shelving system may also be heightened by connecting additional ancillary panels to each of the walls.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

shows a preferred embodiment of the present invention. In

FIG. 1

, a shelving assembly


10


is shown having a first wall


20


and a second wall


30


. Each wall is substantially upright and substantially flat. The walls are preferably made from aluminum but other materials may be used. The walls may have a clear anodized finish. The walls are shaped by conventional fabrication techniques including but not limited to metal stamping.




Extending between the walls are a plurality of bridging members


40


. Bridging members


40


are preferably made from a rigid material such as, for example, aluminum. The bridging or horizontally disposed member may also be made from a transparent material. Bridging members


40


serve at least two functions. First, bridging members


40


support articles


145


. While articles


145


are shown as standard-sized compact disk cases, other articles can be shelved on bridging members


40


. Preferable articles include but are not limited to compact disks, digital video disks, floppy disks, tapes, and books. The bridging members can also have various cross sections. For example, a rectangle may be a suitable cross section for a bridging member so long as its surface is capable of supporting certain articles. Further, a single bridging member can be used rather than a plurality of bridging members


40


.




A second function of bridging members


40


is to firmly connect shelving system


10


. As illustrated in FIG.


2


A and

FIG. 2B

, a portion of base panel


50


and ancillary panel


60


are clamped between one of bridging members


40


and a fastener


90


. The fastener


90


extends through an aperture


100


and connects with an end of one of bridging members


40


. For clamping to be effective, apertures


100


must have a diameter less than the outer diameter of end


45


of the bridging members


40


as well as a diameter less than the outer diameter of the head


95


of fastener


90


. While the embodiment shown in

FIGS. 1-3

shows a circular aperture, other shaped opening can be used. It should also be noted that while fastener


90


can be a screw or rivet, other suitable fasteners may be employed. Alternatively, base panel


50


to ancillary panel


60


may be held in place with binding or C-shaped clips. The binder clips clamp onto both base panel


50


and ancillary panel


60


, holding the panels in alignment. The binder clips may be made from a resilient or flexible material.




Though the clamping action, described above, imposes a frictional force which inherently limits vertical displacement of base panel


50


from ancillary panel


60


, secure vertical locking is primarily achieved due to the shape of base panel


50


and ancillary panel


60


. As illustrated in

FIG. 3

, base panel


50


has a shaped upper profile


150


and ancillary panel


60


has a shaped lower profile


160


. Upper profile


150


and lower profile


160


are matching or mating. Where the matching profiles interlock, an interface


180


is formed as shown in FIG.


1


. Upper profile


150


and lower profile


160


fit together similar to jigsaw-puzzle pieces and once positioned together, cannot be pulled apart if held in the same plane. Like a jigsaw puzzle, the shape of the upper profile


150


and lower profile


160


can be smoothly curved or jagged so long as the two profiles interlock. It should also be noted that each of the first wall


20


and second wall


30


may often be in an upright or vertical position. Even if the panels are not substantially vertical, however, the panels can still be interlocked as long as the panels are positioned together in the same plane.





FIG. 4

shows another embodiment of the present invention. The shelving system


200


is similar to shelving system


10


described in

FIG. 1

except that each wall


210


,


220


has two additional panels


250


,


260


. Additional bridging members


270


are provided to maintain a secure connection between additional panels


250


,


260


. The additional bridging members


270


provide the advantage of enabling extension of the shelving system vertically, increasing storage capacity of the shelving system.




Top panels


276


,


277


are shown attached to the tops walls


210


,


220


. Likewise, bottom panels


278


,


279


can be attached to the base panels of walls


210


,


220


. The bottom panels


278


,


279


provide enhanced stability of shelving system


200


.





FIG. 5

illustrates yet another embodiment of the present invention. In

FIG. 5

, shelving system


300


is essentially the same as the shelving system


200


described in

FIG. 4

except that a third wall


310


is provided. Third wall


310


is secured to second wall


320


with additional bridging members


330


. Note that the base and ancillary panels of second wall


320


are fastened together between rigid bridging members


330


and


340


and not, as shown in

FIG. 2B

, between a rigid bridging member


40


and head


95


of fastener


90


. Shelving system


300


, therefore, has an additional advantage of extending horizontally as well as vertically over the shelving system


10


shown in FIG.


1


. Extending the shelving system horizontally as well as vertically increases the storage capacity.




While the walls shown in

FIG. 5

have identical heights, each wall in the present invention is not required to have the same height. As illustrated in

FIG. 6

, each of the walls


400


are not equal in height. Shelving system


410


can therefore be built to accommodate a wide range of spatial restrictions yet still provide maximum storage capabilities. As illustrated by the embodiment shown in

FIG. 6

, over 200 articles can be stored. The number of articles


420


, however, may be changed by building more or less article storage modules.




While the above description and drawings provide specific embodiments of the invention, the present invention is not intended to be limited to those particular forms. Rather, the invention is intended to cover all modifications and equivalents falling within the scope of the following claims.
