Abstract:
1. A clamping device comprising: a fixed jaw; an elongate support structure having a proximal end and a distal end, wherein the elongate support structure carries the fixed jaw at or near to its proximal end; a surface-bearing foldable frame attached to and supporting the elongate support structure; an elongate fixed track having a proximal end and a distal end, wherein the elongate fixed track is immovably mounted on the support structure; a movable jaw; a sliding track movably mounted on the fixed track, wherein the sliding track carries the movable jaw; an advancing clamping mechanism mounted on the support structure for advancing the sliding track along the fixed track towards the fixed jaw in a longitudinal direction; and a transportation mechanism attached to at least one of the proximal end of the elongate support structure and the fixed jaw, wherein the transportation mechanism is configured to facilitate surface-bearing transportation of the clamping device, wherein the transportation mechanism comprises a rotatable shaft mounted on the proximal end of the elongate support structure and a wheel mounted on the rotatable shaft, wherein the rotatable shaft is substantially perpendicular to the longitudinal direction of the sliding track, wherein the foldable frame includes a first leg pivotally mounted on the proximal end of the elongate support structure about a first axis, a second leg pivotally mounted on the proximal end of the elongate support structure about a second axis and a third leg pivotally mounted on the distal end of the elongate support structure about a third axis and wherein the foldable frame has a first, second and third position, wherein in the first position, the first, second and third legs together support the elongate support structure and wherein in the second position, the first, second and third legs are folded for storage and wherein in the third position when the transportation mechanism engages the surface, the first and second legs are folded for storage and the third leg is folded rearwardly to provide a transportation handle and the elongate support structure is inclined relative to the surface by lifting the transportation handle.
