US Patent 10562172 Pole apparatus

Various embodiments of pole devices are described having inner and outer poles or segments that allow for telescoping of the pole device. The inner and outer poles can each include one or more flat side wall portions, which act to thereby prevent rotation of the inner and outer poles with respect to each other. Each of the inner and outer poles can include one or more apertures that are sized to receive a pin to thereby couple the inner and outer poles. One or more gaps may be formed between the inner and outer poles that is sized to receive a burr of at least one of the inner or outer pole.
