Description




BACKGROUND




The present invention relates generally to a storage unit, and in particular, to a modular storage unit.




Typically, storage units, such as file cabinets and the like, are made of one or more pieces of sheet metal or wood, which pieces typically are permanently affixed together by welding and the like. Storage units of this nature are usually assembled at a manufacturer's facility by skilled workers, rather than by the end user. In addition, each storage unit is typically configured in a particular size that cannot be easily modified. As such, the storage units often require large amounts of storage space for inventory, and, due to their bulky size when assembled, can be expensive to ship. In addition, many conventional screens cannot be shipped by commercial carriers due to the relatively large size and weight of the screens. For example, United Parcel Service (UPS) has a size limitation of a 130 cumulative inches, which is defined as the circumference of the product plus the height thereof. Since many customers desire to have products shipped via such carriers, whether through orders placed on the internet or over the telephone, it can be advantageous to provide a storage unit meeting such size limitations. At the same time, many customers desire storage units that can be easily assembled without the need for special tools, and which are light weight and portable.




In addition, many conventional storage units cannot be easily reconfigured by the end user to increase or decrease the storage volume, so as to accommodate changing storage needs. Moreover, conventional storage units, such as filing cabinets, can be relatively plain in their appearance.




SUMMARY




Briefly stated, in one aspect of the invention, one embodiment of a storage unit includes a first and second horizontal shelf member, at least one vertical panel disposed between the first and second horizontal shelf members, and at least one tie member. A bottom of the at least one vertical panel is supported by the first shelf member and the second shelf member is supported on a top of the at least one vertical panel. The at least one tie member extends between and connects the first and second horizontal shelf members, with the at least one panel clamped therebetween. In another aspect of the invention, a method for assembling a storage unit is provided.




In a preferred embodiment, the at least one panel comprises a pair of side panels, and the storage unit further comprises a back panel extending between the side panels and a front panel connected to one of the side panels.




In another aspect, an alternative preferred embodiment of the storage units further includes a third shelf, at least one second panel and at least one second tie member. A bottom of the second panel is supported on the second shelf and the third shelf is supported on a top of the second panel. The second tie member extends between and connects the second and third shelf members.




In another aspect of the invention, a storage unit kit has components capable of being assembled into a storage unit. The kit includes a plurality of shelf members, a plurality of side panels, at least one back panel, a plurality of tie members and at least one front panel.




The present inventions provide significant advantages over other storage units. For example, the storage unit can be easily reconfigured by adding additional levels of storage to accommodate the user's needs. In addition, the components of the storage unit can be shipped in an unassembled state and can then be assembled by the end user so as to reduce the shipping volume and attendant expense. Preferably, such a storage unit meets the shipping requirements of various commercial carriers, like UPS. Moreover, end users can maintain a plurality of various individual components in inventory, rather than a plurality of cabinets. As such, the user can simply use the components as needed to reconfigure the various storage units. In addition, additional levels of storage can be added to the storage unit without having to disassemble already assembled lower levels. Assembly can be accomplished quickly and with minimal effort.




The present invention, together with further objects and advantages, will be best understood by reference to the following detailed description taken in conjunction with the accompanying drawings.

,


90


of the front door, and the side panel, which act as securing members, and is threadably engaged with the insert member


120


in the lower shelf. The lugs


48


,


88


,


90


in combination with the member


110


inserted therethrough form a hinge. In particular, the tie member


110


is engaged between the trough


90


and the lugs


88


, which act as securing members.




In the alternative preferred embodiment of the front panel


180


, the trough


190


pivots about the lugs


48


,


148


of the side panel. At the same time, the tie member


110


extends through and/or is engaged with the lugs


188


,


48


, and


148


of the front and side panels, which act as securing members, and is threadably engaged with the insert member


120


in the lower shelf. The lugs and trough


48


,


148


,


188


,


190


, in combination with the member


110


inserted therethrough, form a hinge.




In either embodiment, each front door


80


,


180


is pivotably or hingedly mounted about the tie member


110


and is thereby connected to the side panel


30


. Preferably, the lugs


48

or securing members of the side and front panels are arranged such that the bottom


84


of the front panel is spaced slightly above the upper surface of the lowermost shelf member.




The upper shelf member


12


is disposed on the side panels


30


, with a bottom


28


of the shelf member being supported on a top


32


of the side panels, and preferably only by the top of the side panels. An insert member


120


is inserted into each opening of the upper shelf, with the flange


124


received in a countersink


116


formed in the upper surface


29


of the shelf member. The insert members


120


are threadably engaged with the upper end


112


of the tie member. A tool, such as screwdriver, can be engaged with the groove


126


formed on the head of the barrel nut to tighten the insert member and thereby put the tie members


110


in tension, with the side panels


30


clamped between the shelf members


12


in compression.




Additional levels of storage can be easily added without having to disassemble the existing storage unit, regardless of whether it is already one or more levels. Rather, a pair of side panels


30


are simply disposed on the upper surface


29


of the uppermost shelf member


12


of the existing storage unit. A back panel


50


is then positioned between the side panels


30


. If desired, one or more front panels


80


can be positioned between a front of the side panels. Tie members


110


are then engaged by the securing members of the respective panel members and are threadably engaged with a top of the insert members


120


recessed in the countersink of the uppermost shelf member of the existing storage unit. Since the insert members


120


are threaded all of the way through, they serve both as tightening member for the lower tie members and as a nut for the upper tie members.
