发明名称 Retractable court standard and methods of use
摘要 An improved retractable court standard is described. The retractable court standard typically comprises a plurality of elongated tubular sections and an elongated top section. Each of the elongated tubular sections has a top end and a bottom end, and different dimension. Additionally, the elongated top section typically has a top end and a bottom end, and a net securing assembly coupled proximal the top end. At least one elongated tubular section is slidably and rotatably disposed within another circumferentially adjacent elongated tubular section. Importantly, the at least one elongated tubular section has one of at least one rotational locking channel and at least one securing pin. The circumferentially adjacent elongated tubular section has the other of the at least one rotational locking channel and the at least one securing pin. Methods of extending, retracting, and storing the improved retractable court standard are also described.
