Abstract
An elongate body adapted to bend in a single plane, comprises 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 said 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.
Claims23
An elongate body, comprising:
- a rope extending within a succession of individual tubular elements closely spaced along the rope, each element having on two opposite sides of a single 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 said single plane,
- wherein there is no radial overlap between adjacent tubular elements, and
- wherein the elongate body is adapted to bend in said single plane.
A flexible plate comprising a plurality of elongate bodies wherein each elongate body 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 a single 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 said single plane, wherein;
- there is no radial overlap between adjacent tubular elements,
- the elongate body is adapted to bend in said single plane, and
- the bodies are laid side to side with tubular elements in each body linked to those in the neighbouring body.
A security device comprising an elongate body adapted to bend in a single plane, the elongate body comprising a rope extending within a succession of individual tubular elements closely spaced along the rope, each element having on two opposite sides of said single 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 said single plane but define the limits to which the elongate body can be bent in said single plane, the tubular elements having on a third side substantially perpendicular to said single plane juxtaposed sections that restrict bending of the body to one direction in said single plane, wherein a cut-resistant material is applied to each tubular element, and wherein there is no radial overlap between adjacent tubular elements.
