Abstract
Abstract A workbench includes a top structure and a supporting structure for supporting the top structure above the floor. The top structure includes a three part vice, one part being a first elongate vice member and the second and third parts together forming a second elongate vice member extending in side-by-side relationship with the first elongate vice member, the two elongate vice members having opposed clamping faces. A first vice operating arrangement causes movement of the clamping face of at least one vice member towards and away from the clamping face of the other vice member. A second vice operating arrangement causes relative movement of the second and third parts in a direction parallel to the direction of elongation of the vice members to permit clamping of objects between opposed further clamping faces of the second and third parts.
