  • a pair of end bulkheads 40 and 42 are placed in grooves 24 and 30, respectively, of sub-top 20.
  • Bulkheads 44 and 46 are positioned in grooves 26 and 28, respectively, of sub-top 20.
  • These bulkheads are then fastened to the sub-top member.

Grooves can also be provided in the inner surface of the back panel 16 at sides 54 and 56 and in the central portion for the positioning of bulkhead members 40, 44; 46, and 42, respectively.
  • the bulkhead members are then fastened to the back member 16 through suitable mechanical fastening means such as screws, or by chemical adhesives.
  • a knee wall panel is then placed into groove 32 between bulkheads 44 and 46,- and is attached to each of these members by screws, nails, or by employing a suitable chemical adhesive.
  • the bottom member 64 will be placed between bulkheads 40 and 44.
  • notches are provided in the bottom portion of bulkheads 40 and 44 at 41 and 45, respectively.

  • the sixth side of the box can be omitted without any loss in torsional strength.
  • the middle box has two sides which have a high or a low length to width ratio. In this case, the ratio will be generally greater then 1.5/1, or less than .67/1 (depending on terminology for leng'h and width). In this box, all six sides have structural members.
  • submembers such as 20, 40, and 42 have portions cut out in the middle of the sides of the structural boxes. It has been found that for torsional strength, the middle sections of the sides of the boxes can be omitted.
  • FIG. 4 shows the method of constructing the desk once the assembly has been provided.

  • the front will have drawers or doors covering each open-ended box.
  • the finished panels can be wood, plastic, or any other suitable material which can serve as a decorative outer surface for the furniture.
  • torsional strength for any given box structure is a function of the cube of length of a side so long as the sides are of a thickness substantial enough to withstand the strain. Further, it is known that a cube has high torsion resistance as compared with a flat board, for example. Thus, the interlocking box structure will maximize torsional resistance with a minimum of weight.
  • panel stock is employed.
  • one embodiment of the invention includes the construction of furniture wherein a subassembly as such is not employed.

  • the end structure also provides a means for positioning the end panel and since the end panel is coextensive with the bars, which are attached to the U-shaped member, the ends of the panel need not be finished either.
  • the end construction also provides a means for attaching the legs to the main body of the furniture through tabs 70, whereby the means for attaching the leg structure will be hidden from view.
