Abstract
Abstract A golf training aid (100; 140) is provided and includes first and second pairs of telescopically extendable rails (16, 18; 16', 18') and a pair of adjustable rails (102, 104; 142, 144). Screws (116, 130; 164, 166, 184, 186) adjust adjustable rails (102, 104; 142, 144) and maintain rails (16, 18; 16', 18') in an operational position and a folded storage position. Rails (102, 104) include pivotable members (106, 112, 120, 122) and rails (142, 144) include telescoping sections (152, 156, 158, 174, 176, 180).
