Abstract
A telescoping rod assembly (10) including an outer tube section (12) and an inner tube section (14) that is slidable disposed inside the outer tube section. The tube sections are locked into position relative to each other by a packing washer (18) that is fitted around the inner tube section adjacent the open end of the outer tube and a locknut (16) that is fitted around a inner tube and is rotatably secured to the open end of the outer tube. The inner tube and the locknut are provided with complementary outer and inner non-circular surfaces so as to couple the two members together so that they rotate in unison. The locknut can be tightened down over the packing washer to secure the tube sections into position relative to each other by the simple act of either rotating the outer tube or the inner tube.
Claims20
A telescoping rod assembly including:
- an outer tube having an open end;
- an inner tube slidably disposed in said open end of said outer tube;
- a locknut disposed over said open end of said outer tube and around said inner tube, said locknut being releasably coupled to said outer tube so that said locknut can be selectively moved longitudinally relative to said outer tube by the rotation of either said locknut or said outer tube, and said locknut being further configured to interlock with said inner tube so that said locknut and said inner tube rotate in unison;
- and
- a locking element disposed between said inner tube and said outer tube underneath said locknut for imposing a compressive force on said inner tube when said locknut is moved toward said outer tube.
A telescoping rod assembly including:
- an outer tube and an inner tube slidably disposed in said outer tube, said outer tube having an open end through which said inner tube extends;
- and
- a locking assembly including a compressible locking element located adjacent said open end of said outer tube and disposed around said inner tube and a locknut secured over said open end of said outer tube and around said inner tube and said locking element, said locknut being releasably coupled to said outer tube so that said locknut can be selectively moved longitudinally relative to said outer tube by the rotation of either said locknut or said outer tube and said locknut being coupled to said inner tube to rotate in unison with said inner tube.
