发明名称 Collapsible sport pole
摘要 A sports pole includes two to four elongated tubular members permanently joined together with a first of the tubular members or poles pivotably joined near one end to a second of the poles. A third of the poles may be telescopically received within or about the first pole and slidingly movable therealong between retracted and extended positions. There is a U-shaped spring and pin arrangement for locking the third tubular member in the extended position. A fourth of the poles may be telescopically received within or about the second pole and be similarly slidingly movable therealong between retracted and extended positions. Again, there is a U-shaped spring and pin arrangement for locking the fourth tubular member in the extended position. The first and second tubular members are pivotably joined by a hinge mechanism which allows selective pivotal motion between generally coaxial and generally parallel positions. A locking arrangement prevents pivotable motion between the first and second members when the first and second members are in the coaxial position. This unique combination of hinging with telescoping allows compacting of the sports pole structure with no disassembly.
