Title: Innovations by Mark S Granger
Introduction
Mark S Granger is an accomplished inventor based in Worthington, OH (US). He holds a total of 3 patents that showcase his innovative contributions to the field of engineering and design. His work primarily focuses on the development of advanced sign post systems that enhance safety and functionality.
Latest Patents
One of his notable inventions is the "Sign post with stress-defined breakaway splice." This invention features a sign post formed of a lower support component that anchors within the terrain, leaving an exposed upper portion at the surface. The support component includes an array of longitudinally regularly spaced apertures. An upper support component, which has the same regular spacing of apertures, is attached to the lower component using a unique splicing technique. This splice acts as a stress transfer component with strategically positioned boltways, allowing for a more structurally definable joint that can yield under load.
Another significant patent is the "Sign post with breakaway splice." Similar to his previous invention, this sign post consists of a lower support component for anchoring within the terrain and an upper support component with the same cross-sectional configuration. The splice is designed as a stress transfer bar with strategically positioned bores, ensuring that breakaway bolts are properly spaced. This design allows the sign to withstand wind loadings while ensuring it breaks away safely when struck by a vehicle.
