摘要： A sign post constructed of an upper channel section nested with a lower channel section at a frangible joint designed so when the sign post is struck by a vehicle, failure of the joint will occur in a predictable and consistent manner. The channel sections are preferably formed of stock channel material having a transverse cross-section in the general shape of a hat, including a longitudinally extending flat center web and outwardly divergent side walls. When the channel sections are nested together, the side walls of adjoining sections are in contact with one another, while the web portions remain spaced apart. In the present invention, the channel sections are connected together with a fastener in combination with a spacer that is engaged between the web portions to provide a reliable and strong breakaway connection.

摘要： A sign post is formed of a lower support component for anchoring within terrain, leaving an exposed upper portion at the surface of such terrain. The support component includes an array of longitudinally regularly spaced apertures. An upper support component having the same regular spacing of apertures is attached to the lower component at the exposed portion through the utilization of a splicing technique. The splice is formed as a stress transfer component having two strategically positioned boltways therein. These boltways are spaced apart longitudinally a distance representing an even integer of the upper and lower component aperture spacings. The boltways are configured having a small threaded region adjacent one surface. Bolts having a threadless shank and threaded region therebelow are slidably inserted through one of the components into the stress transfer whereupon they are rotated for preassembly engagement with the minor threaded regions of the stress transfer component. In the course of sign assemblage, the bolts are tightened to deform or strip the threads within the stress transfer component. When the splice is completed by the addition of nuts to the ends of the bolts, the bolts are substantially unrestricted by threaded engagement within the stress transfer component and the splice or joint affected is more structurally definable, permitting the bolts to yield along their lengths under load.

摘要： A sign post is formed of a lower support component for anchoring within terrain, leaving an exposed upper portion above the surface of such terrain. The support component includes an array of longitudinally regularly spaced apertures. An upper support component formed having the same cross-sectional configuration and regularly spaced apertures is attached to the lower component at the exposed portion through the utilization of a splicing technique. The splice is formed as a stress transfer bar having two strategically positioned bores therein. These bores are spaced apart longitudinally a distance representing an even integer of the upper and lower component aperture spacing. Breakaway bolts are positioned through one of the components and into and through the stress transfer bar, and then the second component is attached with nuts being positioned and tightened over the bolts as they extend through the stress transfer bar. This assures that the bolts will be properly longitudinally spaced such that the sign will properly break away when struck by an errant motor vehicle, but the sign will withstand requisite wind loadings.
