Abstract
A break-way coupling with spaced weakened sections includes a central controlled breaking region and rigid threaded bolts at each end for connection to a base at one end and to a pole or the like at the other end. The controlled breaking region includes two axially spaced necked-down portions of smaller diameter and solid cross-section. Where the axil length of the controlled breaking region is L and the necked-down portions have a diameter D, the dimensions D and L are selected so that the ratio D/L is within the range D/L.ltoreq.0.3. The necked-down portions have conical tapered surfaces to insure that at least one of the necked-down portions break upon bending prior to contact between any surfaces forming or defining the necked-down portions.
