Abstract
An elongate body adapted to bend in a single plane, includes a rope extending within a succession of individual tubular elements closely spaced along the rope. Each element has on two opposite sides of the plane an extended section engaging a recess in its neighbouring element, the profiles of the section and recess allowing relative rotation of adjacent elements in the plane. The tubular elements thus form an exoskeleton around the rope which must be breached before the rope can be cut. The geometry of the tubular elements can be such that notwithstanding gaps, the rope cannot be readily accessed unless the exoskeleton is broken.
Claims21
An elongate body adapted to bend in a single plane, comprising:
- a rope extending within a succession of individual tubular elements closely spaced along the rope, each tubular element having on two opposite sides of the plane an extended section engaging a recess in its neighbouring element, the profiles of the section and recess allowing relative rotation of adjacent elements in the plane,
- wherein each tubular element comprises a single metal pressing cut to shape and closed into a tube with closing edges secured by one of crimping, clinching, and welding;
- or
- wherein each element comprises two matching metal pressings cut to shape and closed into a tube with the closing edges secured by one of crimping, clinching, and welding.
A flexible plate comprising a plurality of bodies, wherein each body is adapted to bend in a single plane and comprises a rope extending within a succession of individual tubular elements closely spaced along the rope;
- each element in the succession having, on two opposite sides of the plane, an extended section engaging a recess in its neighbouring element, the profiles of the section and recess allowing relative rotation of adjacent elements in the plane, and wherein the bodies are laid side to side with tubular elements in each body linked to those in the neighbouring body;
- wherein each element comprises a single metal pressing cut to shape and closed into a tube with closing edges secured by one of crimping, clinching, and welding;
- or
- wherein each element comprises two matching metal pressings cut to shape and closed into a tube with the closing edges secured by one of crimping, clinching, and welding.
A security device comprising an elongate body adapted to bend in a single plane, comprising:
- a rope extending within a succession of individual tubular elements closely spaced along the rope, each element having, on two opposite sides of the plane, an extended section engaging a recess in its neighbouring element, the profiles of the section and recess allowing relative rotation of adjacent elements in the plane but define limits to which the body can be bent in the plane, the tubular elements having on a third side, substantially perpendicular to the plane, juxtaposed sections that restrict bending of the body to one direction in the plane, and wherein a cut-resistant material is applied to each tubular element;
- wherein each element comprises a single metal pressing cut to shape and closed into a tube with closing edges secured by one of crimping, clinching, and welding;
- or
- wherein each element comprises two matching metal pressings cut to shape and closed into a tube with the closing edges secured by one of crimping, clinching, and welding.
