DESCRIPTION OF THE PREFERRED EMBODIMENT AND BEST MODE

Referring now specifically to the drawings, a preferred embodiment of the knockdown furniture assembly according to the present invention is illustrated in FIG. 1, and shown generally at reference numeral 10. The furniture assembly 10 generally comprises a frame 11 releasably connected to two arm pieces 12, 13. The frame 11 is preferably rectangular with sides 11 a-d, and the arm pieces 12, 13 are positioned on opposite sides 11 a, 11 d of the frame 11. The frame 11 and arm pieces 12, 13 are preferably made of wood.
Each arm piece 12, 13 is identical, and therefore, only one arm piece 12 will be described in detail. As shown in FIG. 2, arm piece 12 comprises two vertical members 12 a, 12 b, joined together by a horizontal top rail 12 c, and a double bottom rail 12 d. Two holes 13, 14 are formed in the bottom rail 12 d of the arm piece 12. Carriage bolts 15, 16 are inserted into the holes 13, 14, and fastened to the rail 12 d by tightening suitable fasteners, such as flat washers 17, lock washers 18 and nuts 19, on the carriage bolts 15, 16. The fasteners 17, 18, 19 are countersunk in the rail 12 d to allow for a flush connection between the rail 12 d and the frame 11.
At this point, the arm pieces 12 can be upholstered. When upholstering the arm piece 12, the side of the rail 12 d facing the frame 11 is left unupholstered, and the heads of the carriage bolts 15, 16 on the opposite side of the rail 12 d are also left exposed. The heads of the carriage bolts 15, 16 are uncovered so that the carriage bolts 15, 16 can be removed or replaced during future reupholstering if necessary.
The frame 11 is upholstered separately from the arm pieces 12, 13. The surfaces of sides 11 a, 11 d, facing the arm pieces 12, 13 are left unupholstered.
Sides 11 a, 11 d of the frame 11 are identical, and therefore only side 11 d will be discussed in detail. As shown in FIG. 2, two apertures 20, 21 are drilled into frame side 11 d. The exposed sections of the carriage bolts 15, 16 extending outward from the rail 12 d are inserted into the apertures 20, 21 of the frame side 11 d and fastened by tightening flat washers 22, lock washers 23 and nuts 24, as shown in FIGS. 2, 3 and 3A.
A seating support 25, such as for a futon as shown in FIG. 4, is mounted on the frame 11. Both the frame 11, and the arm pieces 12, 13 are upholstered at this point, and the seating support 25 is upholstered to form the upholstered furniture assembly 10 shown in FIG. 5. The finished furniture assembly 10 is sturdy and strong, and can be easily disassembled for delivery through into lofts and small rooms. For example, arm piece 12 can be disconnected from the frame 11 by disengaging the fasteners 22-24 and withdrawing the carriage bolts 15, 16 from the apertures 20, 21 in frame side 11 d. The identical process is used to disconnect arm piece 13 from frame side 11 a. With the arm pieces 12, 13 separated from the frame 11, the frame 11 and the arm pieces 12, 13 can be more easily transported through door openings, hallways, stairwells and other narrow passages. The frame 11 and arm pieces 12, 13 can be reassembled by simply repeating the steps described above.
In an alternative embodiment, the furniture assembly is a sofa with an upholstered back piece. In such an embodiment, the arm pieces include a vertical member having holes to accept carriage bolts that are inserted into a second frame positioned vertically. The second frame is connected to the vertical members of the arm pieces in the same manner as described above for frame 11 and bottom rail 12 d. The upholstered back piece of the sofa is mounted in the second frame.
A knockdown furniture assembly and a method for making same is disclosed above. Various embodiments of the invention can be made without departing from its scope. Furthermore, the foregoing description of the preferred embodiment of the invention and the best mode for practicing the invention are provided for the purpose of illustration only and not for the purpose of limitation—the invention being defined by the claims.
