Abstract
The present invention is an improved apparatus and method for forming a retractable tower or column. The present invention includes pointed hooks (4 0, 42) wherein the hooks (40, 42) are attached to each section of a section cha in (22),one (40) in a horizontal direction and one (42) in an off-set manner. T he section chains (22) are placed on a take-up mechanism (80) in an operable position and then raised utilizing a motor. As the section chains (22) are raised, they are guided by a guide tower (118), rollers (112, 114, 115, 117) shims (116), and gear racks (36) into a position whereby hooks (40, 42) from adjacent sections (22) of the section chains (22) form coupled engagements. The coupled engagement of the hooks (40, 42) of the sections of each adjacen t section chains (22) thereby form the column.
