Abstract
A clamping member (11) for a wood clamp (10) is provided and comprises two spaced engaging elements (14, 15), each shaped as right oval cylinders. The engaging elements are rotatably mounted to a support plate (17) and are arranged to slide relative to support plate in respective slots (16) which converge. A workpiece is arranged to be clamped between the engaging elements when it is moved in the direction in which the slots converge as movement of the workpiece causes the engaging elements to slide in the converging slots thus further gripping the workpiece and also rotate until such time as the engaging elements clamp the workpiece and prevent further movement of the workpiece.
Claims23
A clamping member comprising:
- a support plate;
- a pair of engaging elements each having a wall surface, at least a portion of the wall surface of each engaging element being arcuate in shape and being formed from a non-slop material,
- a pair of retaining means provided in the support plate, each respective one of the engaging elements being retained in a respective one of the retaining means such that each engaging element extends outwardly from a first side of the support plate so that the respective wall surfaces of the engaging elements are opposed to each other, each engaging element being slidable in its respective retaining means;
- and
- mounting means between each engaging element and the support plate such that each engaging element can freely rotate relative to the support plate about an axis of rotation, thereby enabling a distance between the opposing wall surfaces of the engaging elements to be varied by sliding the engaging elements in their respective retaining means,
- wherein the mounting means are low friction bearings and rotation of the engaging elements via the low friction bearings from a first position to a second position causes the distance between the opposing wall surfaces to be reduced.
