Break bollard

An improved break bollard including

• a base plate having a central threaded bore and being adapted to be anchored to a stationary support,
• a central post having a removable enlarged cap on one end and a sole plate on an opposite end, and
• threaded bolt means for securing said central post and said sole plate to said base plate
• wherein the improvement comprises:
• an aperture in said sole plate aligned with the central threaded bore in said base plate;
• a threaded portion along one end of said bolt means engaged in said central threaded bore;
• a first head portion on said bolt means terminating said threaded portion;
• a second head portion at the other end of said bolt means, said second head portion being of larger diameter than said first head portion and adapted to engage the sole plate around the periphery of said aperture;
• a weakened region of incipient fracture on said bolt means between said first and second head portions;
• and
• said threaded bolt means being tightened into said base plate for retaining the sole plate on said base plate;
• and
• said weakened region of incipient fracture being fractured in response to excessive force on the central post whereby the first head portion on said bolt means and its attached threaded portion in said base plate may be removed by rotation of said first head portion which is located beneath the weakened region of incipient fracture.
