VIBRIX spring is a special type of extension spring, suitable for applications with large elongation and non-increasing load. Constant force springs consist of spiral metal strips; the inner side of the strip is curved so that each coil wraps tightly around the inner coil. When the metal strip is stretched (twisted), internal stress resists the load force, exactly like a standard extension spring, but the coefficient remains nearly constant (zero). See the load/torsion diagram. In use, an ID is typically used to wind this spring tightly onto a drum, with its free end connected to the load, just like
