US Patent 11028544 Indestructible mailbox post

An indestructible mailbox post includes a lower post that is buried in the ground surface and may be secured in the ground with a concrete or other material. The lower post is buried to a depth such that a spring element, interposed between the lower post and an upper post is positioned proximal, and preferably slightly above the ground surface. With the upper post coupled to the lower post via the spring element the upper post is free to flex about the spring element when acted upon by a force to preclude breakage of the post.
