DEFINITION

Classification: 52/155

(under the class definition) Structure including anchoring means having a component which in use is held below ground and which holds another component usually extending above the earth's surface, which means has (1) a feature for piercing the earth or (2) an anchor component which moves outwardly relative to the element held and thereby acts to prevent or retard movement of the latter relative to the earth.
