ABSTRACT:
An improved rural mailbox mounting structure for road-side use which is less subject to damage due to impact from snowplows and the like. A platform on which the mailbox is attached is connected to a tubular sleeve bearing at a predetermined angle. Affixed to a mounting post and extending outwardly therefrom toward the road in a horizontal plane is a mounting plate. Secured to the mounting plate is a cylindrical rod which extends upwardly therefrom at an angle which is the supplement of the predetermined angle formed between the mailbox mounting platform and the longitudinal axis of the sleeve bearing. Therefore, when the sleeve bearing is positioned over the cylindrical rod, gravitational force tends to maintain the mailbox platform in a horizontal plane. When the mailbox is struck, it yields to the striking force and rotates about the cylindrical rod as an axis. When the force is removed, gravity again returns the mailbox to its normal position.
