Abstract
A bollard assembly is formed from a bollard that resides in a tubular socket. The socket has an internal core that is separated from the tube walls by annular recess. The lower end of the bollard is received within the recess. Lifting elements inside the bollard engage the upper surface of the core, and are internally biased in favor of extension. A locking system prevents extension of the lifting elements. When the locking system is unlocked, the pressure of the lifting elements against the core causes the bollard to rise out of and slightly above the socket, without external assistance. Once raised, the bollard may easily be removed from the site of the socket.
