System for dense packing of ready-to-assemble articles of furniture

Abstract

A system for constructing and shipping full-sized (or larger) RTA articles of furniture in a smaller volume, resulting in more efficient and dense packing of multiple articles on standard international cube shipping containers. Each full-sized or larger RTA article of furniture is constructed so that it in a partially assembled state it can be arranged and packed in a shipping box or container of 26.5 inches or less in height and 30.6 inches or less in width. Lengths may vary, but common lengths are 45 inches, 66 inches, and 90 inches. The system thus results in a substantial increase (approximately 33%) in the number of articles of furniture that can be shipped in a single standard international cube shipping container, thereby greatly reducing the shipping cost per article of furniture.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

(9) In various embodiments, the present invention comprises a system for constructing and shipping full-sized (or larger) RTA articles of furniture in a smaller volume, resulting in more efficient and dense packing of multiple articles on standard international cube shipping containers. As described below, each full-sized or larger RTA article of furniture is constructed so that it in a partially assembled state it can be arranged and packed in a shipping box or container of 26.5 inches or less in height and 30.6 inches or less in width. Lengths may vary, but common lengths are 45 inches, 66 inches, and 90 inches. The shipping boxes or containers further are designed to be efficiently and densely packed in the standard intermodal shipping container regardless of orientation or configuration. The present invention thus results in a substantial increase (approximately 33%) in the number of articles of furniture that can be shipped in a single standard international intermodal cube shipping container, thereby greatly reducing the shipping cost per article of furniture.

(10) An intermodal container is a large, standardized shipping container, designed for intermodal freight transport, where goods are stored and transported across different modes of transport (e.g., ship, rail, truck) without unloading or reloading of the cargo. The great majority of global intermodal containers are referred to as “dry freight” or “general purpose” steel or metal containers, that come in either nominal 20 or 40 feet standard lengths, with internal width of 92 inches and internal height of 106 inches.

(11) FIG. 1 shows a comparison of a fully assembled full-sized RTA article of furniture 2 in accordance with the present invention compared to a prior art RTA article of furniture 4. The RTA article of furniture 2 is larger than the prior art article of furniture 4, yet, as described below, can be arranged in a partially assembled state in a smaller volume than the prior art article of furniture. The system and process of disassembling and packing for various articles of furniture is discussed below.

(12) Recliner

(13) FIG. 1 shows an example of a fully assembled full-sized RTA recliner 1 in accordance with the present invention. FIG. 2 shows the recliner in a partially disassembled state, with the major components comprising a back assembly 110, a seat assembly 120, and a base assembly 130. The back assembly, seat assembly and base assembly are connected by various snap-fit fasteners and connectors, as described in U.S. Provisional Application Nos. 61/758,231 and 62/380,933, and U.S. application Ser. Nos. 14/167,249 and 15/049,767, all of which are incorporated herein by specific reference for all purposes. These fasteners and connectors also are used with the sofa, love-seat and other articles of furniture, as described below.

(14) FIGS. 3-7 show the packing process for packing the recliner in a shipping box or container 10 of 26.5 inches or less in height and 30.6 inches or less in width. First, the back assembly 110 is placed in the bottom of the box with the cushion side up. Then, the seat assembly 120 is inverted and placed in the box with the cushion side down. The seat assembly 120 is arranged so that the arm cushions 122 are placed in alignment with the wing cushions 112 of the back assembly This allows for maximum compression of the cushions while protecting the cushions from damage. It also exposes the bottom of the seat assembly and the scissor elements 126 (which are affixed to the seat assembly) and upper cam piece connectors 124. One or more foam inserts 140 are then placed into position on the bottom of the seat assembly, and the base assembly 130, which includes lower cam piece connectors 134 for a snap-fit RTA connection with the upper cam piece connectors, is rotated 90 degrees and placed securely into corresponding slots or holes in the foam inserts. The box can then be sealed and labeled for shipping.

(15) While this order of packing can be reversed/inverted, so that the back assembly is at the top of the box, this arrangement (i.e., back assembly in the bottom) allows the shipping box to be opened and various base assembles to be removed and added (as described in U.S. patent application Ser. No. 62/380,933, which is incorporated herein in its entirety by specific reference for all purposes) without removing the seat assembly and back assembly from the shipping box.

(16) Sofa

(17) FIG. 8 show a fully assembled “2-over-2” full-sized RTA sofa 200 in accordance with the present invention. FIG. 9 show the sofa in a partially disassembled state, with the major components comprising a back assembly 210, a seat assembly 220, and one or more arm pillows 240. The back assembly and seat assembly and base assembly are connected by various snap-fit fasteners and connectors, as described above. As seen in FIG. 10, the arm pillows 240 may be removably attached to the side arms 222 of the seat assembly by zippers or hook-and-loop fasteners, or the like.

(18) FIGS. 11-12B show the packing process for packing the sofa in a shipping box or container 10 of 26.5 inches or less in height and 30.6 inches or less in width. The arm pillows 240 are removed and inserted into the hollow side arms 222 through openings in the bottom of the side arms, as seen in FIG. 11. The back assembly 210, which may be integrated as a single piece or modular (i.e., divided into parts, i.e., the right and left sides as shown in the figures), is placed into the bottom of the box with the cushion side up. The seat assembly 220, which also may be integrated as a single piece or modular, is inverted and placed over the back assembly, cushion side down. This allows for maximum compression of the cushions while protecting the cushions from damage. The packing order can be inverted. The box can then be sealed and labeled for shipping. The above RTA construction and packing methodology also can be applied to a “3-over-3” full-sized RTA sofa. FIGS. 13 and 14 show the sofa is a assembled and partially disassembled state, and FIGS. 14-15B show the packing process for packing the sofa in a shipping box or container 10 of 26.5 inches or less in height and 30.6 inches or less in width, with the back assembly followed by the seat assembly, as described above. In several embodiments, a back wing may be removable and stored as described below. Similarly, the above RTA construction and packing methodology also can be applied to a love seat, as seen in FIGS. 16A-B.

(19) Modular Pieces

(20) In several embodiments, the article of furniture may be wholly or partially modular. Modular pieces can be individually and separately disassembled and packaged, as shown in FIGS. 17A-18B (for a modular armless center piece), FIGS. 19A-20B (for a modular end piece), FIGS. 21A-22E (for a modular end piece with a removable back wing, which is placed in the back space created by removal of the back assembly for the shipping configuration) or FIGS. 23A-E (for a modular console).

(21) Access Door

(22) As seen in FIGS. 24A-B, in several embodiments, the shipping box or container has a closable and sealable access door 190 in the side, positioned where the control element connection port 192 for a recliner or other furniture article is located, thereby allowing access to the control element connection port while the furniture article is still in the box. This allows changes to be made, such as adding a power control element added (such as described in U.S. Patent Application No. 62/382,803, which is incorporated herein in its entirety by specific reference for all purposes) without removing the article of furniture from the box.

(23) Container Loading

(24) Examples of various shipping box or container dimensions, and how they can be densely packed on a single standard international cube shipping container, are shown in FIGS. 25A-28C.

(25) As seen in FIGS. 26A-27D, furniture shipping boxes or cartons 26.25 inches in height and 30.5 inches in width and 45 inches in length can be packed in several orientations without reduction in efficiency in space usage. For example, a vertical stack of 8 total such cartons or boxes can be formed with two cartons placed end-to-end in each row (total of four rows). The same cartons can be rotated to form a vertical stack of 12 such cartons or boxes with three cartons placed side-by-side in each row (total of four rows). One or more rows can be replaced by a “long” carton 90 inches in length (such as for a sofa), but the same height and width. The vertical stacks can be repeated to fill the length of the intermodal shipping container.

(26) Another compatible shipping box or carton size is 23 inches in length (same 26.25 inches in height and 30.5 inches in width; while the “length” of this carton is the shortest dimension, the reference terminology is the same to emphasize that the “height” and “width” dimensions match those of the other cartons). A “half-size” version of this shipping box or carton is 23 inches in length, 30.5 inches in width, but 13 inches in height. FIGS. 28A-C shows a vertical stack with three rows of the 23 inches long standard boxes (four boxes, end-to-end), with a top row of seven of the half-size boxes. The width/depth of the stack is 30.5 inches. This demonstrates that various sizes of the shipping containers can be packed together in different orientations without loss in packing efficiency.

(27) The present invention thus provides for more furniture units to be packed, with greater efficiency, into a single 40 foot long intermodal shipping container. For example, a prior art furniture system can load 19 sofas, 19 loveseats, and 19 recliners (in partially assembled, packed form) on such an intermodal shipping container, while the present invention can load 28 sofas, 28 loveseats, and 28 recliners in the same container, with the assembled furniture being at least as large as the assembled furniture in the prior art furniture system. The packing efficiency, as seen in FIGS. 25A-B, is at least 95.5% (in terms of internal container volume filled/used).

(28) The present system is suitable for all furniture, reclining or non-reclining, where connection is desired, such as, but not limited to, sofas, recliner-sofas, loveseats, recliner-loveseats, chairs, recliner-chairs, sectional pieces, ottomans, rockers, rocker-recliners, gliders, glider-recliners, swivels, swivel rocker, swivel-recliners, and sleeper-sofas, and the like, each with their respective seat boxes and bases.

(29) While the invention has been described in its preferred form or embodiment with some degree of particularity, it is understood that this description has been given only by way of example and that numerous changes in the details of construction, fabrication, and use, including the combination and arrangement of parts, may be made without departing from the spirit and scope of the invention. Thus, it should be understood that the embodiments and examples described herein have been chosen and described in order to best illustrate the principles of the invention and its practical applications to thereby enable one of ordinary skill in the art to best utilize the invention in various embodiments and with various modifications as are suited for particular uses contemplated. Even though specific embodiments of this invention have been described, they are not to be taken as exhaustive. There are several variations that will be apparent to those skilled in the art.
