BACKGROUND OF THE INVENTION

1. Field of the Invention
The invention relates to furniture case goods, which are known to include desks, dressers, shelving cabinets, and the like, and, more particularly, to adaptation of furniture case goods so that they may be collapsed to achieve efficiency in transportation and convenient reassembly.
2. Background Art
Supply chain management is a critical aspect of how goods, including furniture, are made readily available and provided at low cost to customers. Fully assembled case goods are difficult to manage and are thereby relatively expensive to ship and deliver. Fully assembled case goods are not easily delivered to a customer's home, because of stairs, small rooms and other “obstacles” which are typically large, cumbersome items. Fully assembled case goods also occupy large volumes of space in transit from their source of origin to the ultimate customer, and volume increases shipping costs. On the other hand, while unassembled units may be easier to deliver, they require too much time and too much skill to assemble in the customer's home, making this a non-option in supply chain management consideration.
Thus, one appreciates a need for furniture case goods that are efficiently transported, delivered, and placed in a customer's possession for use.

BRIEF SUMMARY OF THE INVENTION

Accordingly, quick assembly furniture of the invention introduces a semi-flat philosophy that addresses the challenges of transportation, delivery, and placement into service discussed above. Quick assembly furniture of the invention provides furniture case goods that comprise various sub-assemblies that are quickly assembled at the location of use, and assembled without requiring special skills. The various sub-assemblies required are in accordance with the nature of the goods being a desk, a book case, and the like.
Further, a unit according to the invention may be easily transported to its final destination, even if such destination is the penthouse suite of a 200-year-old apartment building. While this semi-flat approach to the solution may have a larger carton than traditional ready to assemble (RTA) or knock down, flat pack furniture, typically about 50% larger, quick assembly furniture of the invention will be much smaller than a comparable pre-assembled case good, typically about 75% smaller. Thus, this inventive provides notable improvement, including smaller cartons for easier logistics and a high level fit and finish of the end product.
It will be understood that case goods in accordance with the present invention are susceptible to and facilitate full assembly in the factory prior to packaging and shipment of the case good with the fully assembled case goods being subsequently partially or fully disassembled and thereafter packaged and shipped. The fit, completeness and compatibility of all components of each item of case goods in accordance with the present invention may thereby be positively checked with respect to all other mating components of said item of case goods prior to packaging and shipment.
These and other features, objects, and benefits of the invention will be recognized by one having ordinary skill in the art and by those who practice the invention, from this disclosure, including the specification, the claims, and the drawing figures.

DETAILED DESCRIPTION OF THE INVENTION

A preferred embodiment of quick assembly furniture according to the invention is generally shown in the drawing figures and discussed below. Generally, the inventive concept is premised on hinging multiple panels together sub-assemblies, configuring the sub-assemblies as desired in a partial finished case good configuration, and completing the case good with further panels or sub-assemblies.
Thus, a bookcase of the invention may have a basic sub-assembly of a three sided furniture carcass 1 with a bight panel 1 a and two wing panels 1 b, 1 c (FIG. 1). The bight panel 1 a may have two opposing hinge edges 2 a, 2 b, and one of the wing panels 1 b, 1 c may be hinged with each of the hinge edges 2 a, 2 b. In assembly, the wing panels 1 b, 1 c hinge relative to the bight panel 1 a to a generally U-shaped open sided case configuration as shown in FIG. 1. The wing panels 1 b, 1 c are noted to be generally parallel with one another and generally perpendicular to the bight panel 1 a. Alternatively for shipping, the wing panels 1 b, 1 c and hinges 2 a, 2 b may be folded from the U-shaped configuration to an at least semi-flat panel configuration, not shown.
A box panel that interconnects between the two wing panels 1 b, 1 c and holds the three sided furniture carcass in the U-shaped configuration may be provided in the form of interlocking shelves 3 a, 3 b. A post and keyhole slot bracket interconnection (not shown) as is known in the furniture industry or various other hardware may be used to interconnect the box panel with the shelves 3 a, 3 b as is understood by one having ordinary skill in the art. One may consider the interconnection of the box panel and the three sided furniture carcass basic sub-assembly 1 to form an intermediate assembly.
At least one of a base 4 a and a top 4 b may mate with the intermediate assembly of the three sided furniture carcass basic sub-assembly 1. The top 4 b and the base 4 a may further interconnect between and secure at least the two wing panels 1 b, 1 c. The top 4 b and the base may optionally or alternatively interconnect with the bight panel 1 a as well.
A desk 5 of the invention may have at least one basic sub-assembly of a three sided furniture carcass 1 with a bight panel 1 a and two wing panels 1 b, 1 c that define a desk pedestal (FIGS. 2 and 3). Again, the bight panel may have two opposing hinge edges 2 a, 2 b and the wing panels 1 b, 1 c may be hinged with the hinge edges 2 a, 2 b. In assembly, the wing panels 1 b, 1 c again hinge relative to the bight panel 1 a to a generally U-shaped open sided case configuration as shown.
The wing panels 1 b, 1 c are noted to be generally parallel with one another and generally perpendicular to the bight panel 1 a. Alternatively for shipping, the wing panels 1 b, 1 c and hinges may be folded from the U-shaped configuration to an at least semi-flat panel configuration, not shown.
Some distinctions from the bookcase in implementation of the inventive concept for a desk are noted. One of the wing panels 1 b is adapted as a front panel of the desk pedestal 6 and is configured to accept drawers or doors to provide concealable access to an interior of the pedestal. Also, while the bight panel 1 a defined a back panel of the bookcase above, the bight panel 1 a defines a desk pedestal side panel. Further, the box panel 7 in the desk 5 interconnects between the two wing panels 1 b, 1 c and holds the three sided furniture carcass 1 in the U-shaped configuration. The box panel 7 as used in the desk defines a desk 5 pedestal side panel, rather than a shelf, as in the bookcase embodiment. Additional box panels in the form of shelves may also be used in the desk pedestals 6, although not specifically shown in the drawing figures.
Again, various hardware may be employed. A post and keyhole slot bracket interconnection (not shown) as is known in the furniture industry or various other hardware may be well used to interconnect the box panel with the wing panels 1 b, 1 c as is understood by one having ordinary skill in the art. Various hinging arrangements 2 a, 2 b may be used to hinge connect the wing panels with the bight panel.
By providing a second, mirror image, quick assembly desk pedestal 6 of the invention as discussed above, a second pedestal for a two pedestal desk is provided. A modesty panel 8 may interconnect and position the two pedestals 6. Then, a top 9 may mate with the pedestals. The top 9 may further connect with any or all of the vertical panels, including the wing panels 1 b, 1 c, the box panels 7, and the modesty panel 8.
