Workbench having a plastic clamping work surface

摘要

A portable workbench (10) includes a top structure (14), a support structure (18) and a collapsible frame (20). The top structure (14) includes top members (24) lying in a common plane. The top members (24) include upper working surfaces (26) and lower supporting surfaces. The lower supporting surfaces include a plurality of rib portions (42) formed thereon. The top members (24) further include longitudinally extending opposed side portions (36) defining clamping surfaces. A linkage mechanism (110) cooperates with the frame (20) to actuate the workbench (10) between an expanded working position and a collapsed transport position. A lever (80) releasably cooperates with the frame (20) to maintain the workbench (10) in a locked expanded position.
