Abstract
A safety device may be used to provide separation in the event of a side impact collision. The device may be used in a utility pole guy wire system, interposed between the guy wire and the ground anchor. The device operates in bending. A lateral force of sufficient magnitude applied to the device by the errant vehicle causes a rod within the device to break in tension, even though the tensile strength of the rod may be greater than that of the guy wire. In operation, certain massive portions of the device are tied safely to the ground, while other portions are pulled over the moving vehicle by the tension of the guy wire. The invention may be designed to tolerate axial loads, but to fail reliably when a side force exceeds a desired threshold. When installed in series with a utility pole guy wire, the invention will withstand all normal tensile and incidental loads, and will release when subjected to a high side force as from an automobile impact.
