<p>A known-down type workbench including a three piece support structure assembly (1, 2, 3) which may be assembled in rigid form entirely without the use of nails, screws or other fastening means. The knock-down workbench includes a plurality of table tops (3, 103, 129, 135) which have different functions and are interchangeable. The panels of the workbench are interlockingly stressed to create a structurally tight workbench held together by forces created by the interlocking parts. Thus, the workbench may be lifted or severely jolted without fear of it collapsing.</p> |
