Abstract
The present invention provides fully upholstered, ready-to-assemble furniture which may be custom ordered by a purchaser, shipped directly to the home of the purchaser by a parcel delivery service, and then easily and quickly assembled by the purchaser. The ready-to-assemble article of furniture includes a frame having a composite frame member with a long dimension which is formed by a plurality of planar frame members assembled in an end-to-end and overlapping manner. The plurality of planar frame members are interconnected by interlocking protrusions and cutout portions, as well as by threaded fasteners received in push-in connector elements which are held in recesses within the frame members. The interlocking and threaded fastener connections allow a plurality of smaller frame members to form the composite frame member of the furniture frame, wherein the frame has the torsional and longitudinal stability of known furniture frames which include long, single boards. In particular, the interlocking and overlapping structure of the present furniture frame advantageously provides longitudinal and torsional stability to an article of furniture having a long dimension such as an entertainment center or sofa.
Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


The present invention relates generally to custom ordered furniture and the construction and packaging of such furniture for shipment and storage. More particularly, the invention relates to fully upholstered, ready-to-assemble furniture which may be custom ordered by a consumer, packaged by the seller for shipment to the consumer by a parcel delivery service, and then assembled by the consumer from the packaged components.


2. Description of the Related Art


Ready-to-assemble furniture is furniture which is packaged for shipment and storage in disassembled form, with assembly to be done by the consumer or end user. Examples of existing ready-to-assemble non-upholstered furniture include bookcases, television stands, and simple chairs and benches. Mass merchandized, ready-to-assemble furniture is expected to be rather less expensive to the consumer than comparable pre-assembled furniture or to have distinctive functional features generally not available with its pre-assembled counterpart.


The genre of ready-to-assemble furniture packaged for mass merchandizing sale and home delivery has generally been limited to pieces of furniture which are utilitarian or hard-surfaced. Additionally, when a piece of furniture includes a long dimension, such as the side walls of a tall entertainment center or the front and rear walls of a sofa, it is limited in a shipping capacity by the long straight boards involved in its construction, such that the article of furniture cannot be shipped by a parcel delivery service without incurring additional and expensive charges. For instance, United Parcel Service, Inc. (UPS) presently has shipping limits that, when exceeded, subject the retailer or consumer to additional charges for “particularized delivery.” Specifically, for less expensive non-particularized delivery, packages should only weigh up to 150 pounds, should only be up to 130 inches in length and girth combined, and should only be up to 108 inches in length. Also, packages cannot have any side over 60 inches in length without incurring additional charges. Oversize packages containing furniture with a long dimension (over 108 inches in length or part of a length and girth combination of over 130 inches in length) require special pricing and dimensional weight calculations.


The special pricing not only adds cost to the furniture, but it also delays shipping times and forces the consumer to wait longer for delivery of the furniture. As such, prior ready-to-assemble furniture does not satisfy the need for fully upholstered or other types of ready-to-assemble furniture having a long dimension which may be custom ordered by the consumer and delivered to the household of the consumer by a parcel delivery service using non-particularized delivery.


What is needed is ready-to-assemble furniture of high quality and stable construction which may be packaged in a compact, easily storable and transportable manner, for easy shipment via existing, non-particularized home delivery channels.


SUMMARY OF THE INVENTION

The present invention provides fully upholstered, ready-to-assemble furniture which may be custom ordered by a purchaser, shipped directly to the home of the purchaser by a parcel delivery service, and then easily and quickly assembled by the purchaser. The ready-to-assemble article of furniture includes a frame having a composite frame member with a long dimension which is formed by a plurality of planar frame members assembled in an end-to-end and overlapping manner. The plurality of planar frame members are interconnected by interlocking protrusions and cutout portions, as well as by threaded fasteners received in push-in connector elements which are held in recesses within the frame members. The interlocking and threaded fastener connections allow a plurality of smaller frame members to form the composite frame member of the furniture frame, wherein the frame has the torsional and longitudinal stability of known furniture frames which include long, single boards. In particular, the interlocking and overlapping structure of the present furniture frame advantageously provides longitudinal and torsional stability to an article of furniture having a long dimension such as an entertainment center or sofa.


The plurality of planar frame members are of a suitable size so they may be packaged for non-particularized parcel delivery service. Non-particularized delivery reduces the cost of shipping the furniture and decreases the amount of time the consumer must wait for delivery. Further, the compact packaging gives consumers the option of taking the furniture home from a retail location at the time of sale in their own vehicles, rather than requiring them to wait for particularized delivery by the retailer or another carrier.


Conventional pre-assembled upholstered furniture can be generally classified as having high quality and high cost, or low quality and low cost. The present invention provides ready-to-assemble upholstered furniture of high quality and low cost. In addition, the above advantages enable the novel approach to the sale of fully upholstered furniture involving the custom ordering of furniture by a consumer over an Internet website for quick home, non-particularized, delivery by a parcel delivery service, such as, e.g., UPS.


In one embodiment, an article of furniture is provided, including a frame having a plurality of planar frame members connected to one another, the frame having at least one composite frame member, the composite frame member including at least two frame members coupled to one another in an end-to-end manner.


In another embodiment, an article of furniture is provided including a frame having a plurality of planar frame members connected to one another, the frame including a front wall and a rear wall, at least one of the front wall and the rear wall having a composite frame member, the composite frame member including at least three of the frame members coupled to one another in an end-to-end manner.


In a further embodiment, an article of seating furniture is provided including a frame having a composite frame member, the frame including a seat portion, a backrest portion, a front wall, and a rear wall, at least one of the front wall and the rear wall having a composite frame member, the composite frame member including a plurality of separate planar frame members coupled to one another in an end-to-end manner.


A still further embodiment provides a method of assembling an article of furniture which includes a composite frame member having a long dimension, including the steps of providing a disassembled frame having a plurality of planar frame members, and coupling at least two of the frame members to one another in an end-to-end manner, with the frame members extending along the long dimension of the composite frame member.

Side walls 24 and 26 provide support for arm cushions 36b and 36a, respectively.


Each of the above-described planar frame members are of a suitable size so they may be packaged for non-particularized parcel delivery service as discussed above. The ease of transportation of the shipping packages by merchants or carriers advantageously reduces shipping costs and/or labor. Further, the smaller frame members advantageously allow for compact packaging and gives consumers the option of either receiving home delivery of the furniture by a parcel delivery service, or to easily take the furniture home from a retail location at the time of sale in their own vehicles, rather than requiring them to wait for particularized delivery by the retailer or another carrier.


The number, size and shape of frame members discussed above will vary depending on the article of furniture to be produced. The frame members may be formed of any suitable supporting material, such as pre-finished plywood, oriented strandboard (“OSB”), medium density fiberboard (“MDF”), laminated veneer lumber (“LVL”), solid wood boards, laminated particle board, pre-formed plastic or metal pieces, other varieties of fiber board or strand board, or structural cardboard of honeycombed paperboard. Furthermore, fasteners may not be required for securing the frame members. For example, the interconnection of the frame assembly may instead consist solely of interlocking frame members, or adhesives may be used to join the frame members. The frame members may be prefinished or may consist of unfinished pieces that the consumers may stain and varnish or paint to suit their individual tastes.


The construction and size of the various components of the present invention advantageously provide to consumers ready-to-assemble upholstered furniture of high quality and low cost.


The final steps of construction for article of furniture 20 of FIG. 1 are described in detail in the above-incorporated U.S. Pat. No. 6,568,058. Fabric upholstery covers are draped over frame 21 and secured thereto via hook-and-loop fasteners. Fabric covers are also designed to fit over foam padding elements or pillows made for the various cushions of article of furniture 20. For example, back cushions 30a and 30b are constructed using a fabric cover fitted over a pillow. In contrast, for example, arm cushions 36a and 36b are constructed using a fabric cover fitted over a foam pad. The cushions are then placed on upholstered frame 21 in an arrangement, for example, as shown in FIG. 1.


While this invention has been described as having a preferred design, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
