A portable workbench includes a top structure, a support structure and a collapsible frame. The top structure includes upper work supporting surfaces lying in a common plane and longitudinally extending opposed side portions defining clamping surfaces. A linkage mechanism cooperates with the frame to actuate the workbench between an expanded working position and a collapsed transport position. A lever releasably cooperates with the frame to maintain the workbench in a locked expanded position.

Portable workbench having collapsible support structure

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

Workbench having plastic clamping work surface

A work bench includes a frame, a bench surface on the frame with the bench surface including at least two members, one of which is movable along the frame for clamping a workpiece between the members. A mechanism for moving the member includes two screws coupled with the members. The two screws are spaced with the member for moving the member upon rotation of the screws. A sprocket is coupled with each of the screws. A transmission belt or chain is coupled with the sprockets. At least one handle is coupled with one of the screws to rotate the screws. At least one clutch is coupled with the at least one screw to limit clamping pressure on the workpiece. The clutch enables rotation of one screw with respect to the other screw so that workpieces may be clamped between the members and clamping of the workpiece may be accomplished by rotation of the screws with one hand of the operator. Also, a guard may be present which covers the transmission belt or chain. The handle may include a hub, a straight portion, and curved portion extending from the straight portion. A knob extends from the curved portion.
