ABSTRACT:
A joint structure for joining two pole members is disclosed. A female component of the structure is formed on a first end of a first pole member. At least one, and in some embodiments two, diverging segments are provided on an end of pipe member to form the female component of the joint. A complementing male component is formed on an end of another pipe member. The male component includes at least one, and in some embodiments two, converging segments. The values of the angles and lengths of the converging and diverging segments are preferably as close to each other as possible. The joint structure can be adapted to allow pole members of many different shapes, sizes, and materials to be securely joined together without the need of fasteners such as bolts. Once assembled, the joint structure resists disassembly and lateral deflection of the pole members and provides for long service even under rigorous use.
