Patent ID: 8523135

Claim:
A breakaway device for mounting a post to a foundation comprising: a bottom coupling component having a generally planar upper surface with a first peripheral sidewall flared outwardly at a first incline from said upper surface, and a bottom neck opposite said upper surface for connection to said foundation; a top coupling component having a generally planar lower surface with a second peripheral sidewall flared outwardly at a second incline from said lower surface, and a top neck opposite said lower surface for connection to said post, wherein said top coupling component nests with said bottom coupling component to position said first and second sidewalls in abutting relationship; and, at least one fastener; wherein in a first mode said fastener connects said bottom and top coupling components and maintains said components nested during use, and in a second mode said fastener ruptures when said post is impacted with sufficient force to cause said second sidewall to slide relative to said first sidewall and exert a substantially axial force on said fastener to reach over-tension, allowing said top coupling component to separate from said bottom coupling component.
