Abstract:
A clamp comprising:at least two opposed first clamping surfaces, at least two opposed second clamping surfaces disposed perpendicularly to the planes of the first clamping surfaces, at least two opposed pressure-bearing surfaces spaced apart and located on longitudinal axes of the first clamping surfaces and disposed at an angle from the first clamping surfaces, and two rigid pressure-bearing points, one of said pressure-bearing points located to align when in use adjacent to one of the pressure-bearing surfaces and the other pressure-bearing point located to align when in use adjacent to the other pressure-bearing surface; and means for imparting a longitudinal force such that the pressure-bearing surfaces are urged against the pressure-bearing points and, as the angled pressure-bearing surfaces slide over the pressure-bearing points in response to the longitudinal force, that longitudinal force is translated into a clamping force that urges the opposed clamping surfaces towards each other.
