Abstract: A swinging mailbox support including a vertical post having a horizontal arm and brace disposed thereon wherein a mailbox is affixed to an end portion of the horizontal arm and furthermore the vertical post comprises two portions pivotably interconnected and tending to maintain a neutral initial state by the action of two opposing springs anchored to the ground on either die of the post. A pair of shields are provided to protect the mailbox from direct impact and additionally provide a surface for application of street numbers or other information. In operation the post supporting the mailbox is free to rotate about a central axis in the event of a collision with a vehicle or other object wherein springs restore the mailbox to an initial disposition thereafter.
