ABSTRACT:
A spring includes upper and lower runs of wire interconnected by an intermediate run of wire, all of the runs being integrally formed from spring wire. The opposite ends of the upper and lower runs respectively include hooks and coils while the intermediate run includes a coil. The hooks and coils of the upper and lower runs are used to connect the spring to an adjacent spring with the hook of one spring being received about the coil of an adjacent spring. The upper and lower runs are offset above and below the coils of the upper and lower runs respectively to accommodate a helical wire which is wrapped around the upper run for interconnecting runner wires which extend transversely of the upper run. The runner wires have offset portions which are secured to the upper runs by the helical wire. In one form the coils in the upper and lower runs are provided with a projecting recess or ear for receiving the hooks of an adjacent spring.
