The granted patent (Publication Number: US11904380B2) describes a chain-link net comprising interconnected helices made from high-tensile steel wire, forming a square mesh shape with outwardly curved legs. The curvature radius of the legs imparts a spring capacity to the net, with variations in curvature radius among the helices. The net is designed with specific dimensions and bending angles to enhance its functionality and strength.

The chain-link net device, as outlined in the patent claims, is suitable for various applications such as trapping rocks in mining, slope stabilization, rockfall and avalanche protection, vehicle trapping in motor sports, counter-terrorism, and securing nuts in a force-fitting manner. The net's design features, including the curvature radius of the legs, edge length of the mesh shape, and bending angles, contribute to its effectiveness in different scenarios. Additionally, the use of high-tensile steel wire for the longitudinal elements ensures durability and strength, making it a versatile solution for a range of practical purposes.
