A method of positioning and locking a tube assembly within an architectural opening in a structure, wherein the tube assembly is comprised of a first tube and a smaller diameter second tube, the first tube having a bore, a first end, and a second end; the second tube having a bore, a first end and a second end, the first end partially positioned within the bore of the first end of the first tube; wherein the tubes are rotatable and telescopable relative to each other for changing the overall length of the tube assembly; wherein a locking assembly is contained within the tube assembly in vicinity of the location of where the second tube fits within the first tube, the locking assembly comprising: (i) a screw body having a first end; an opposing second end, the second end fastened to the first end of the second tube; the screw body comprising a screw connected to one of said screw body ends; the screw optionally tapered or of constant diameter and running lengthwise within the screw body, the screw comprising a thread having a thread profile and a pitch, the screw optionally connected to the other of said screw body ends by a wholly or partially unthreaded shaft; wherein the screw has a first thread portion which changes in pitch or in thread profile with distance from the end of the screw body to which the screw is connected; (ii) a sleeve, circumscribing said screw, the sleeve having a threaded bore and an exterior surface portion configured for frictional engagement with the bore of the first tube; wherein the sleeve is threadingly engaged with the screw and thereby movable along the screw when the screw is rotated and the exterior surface of the sleeve is restrained from moving by frictional engagement with the bore of the first tube; and wherein the sleeve further comprises one of (a) a lengthwise split, a diametrically opposed living hinge; (b) a lengthwise split, a diametrically opposed living hinge and resilient pads at the living hinge location; (c) a lengthwise split, a diametrically opposed living hinge and resilient pads the split location; (d) a living hinge and an oblong cross section; and (e) a single turn thread within said bore; telescoping the tube assembly to change the length thereof so the tube assembly fits within an architectural opening or runs between two brackets adjacent an architectural opening; rotating the first tube and second tube relative to each other so that said frictional engagement of the sleeve with the bore of the first tube causes rotation of the sleeve and resultant lengthwise movement of the sleeve along said screw to said first thread portion, wherein the interaction of the sleeve threaded bore with the first thread portion causes the sleeve to expand radially outwardly with increased force against the bore of the first tube until the tubes become locked against relative rotation and telescoping, wherein during said movement of the sleeve a lengthwise thrusting force is imparted to the tubes to increase or decrease the length of the tube assembly as they become locked. The present invention relates to adjustable length rods comprised of telescoping tubes, useful for hanging curtains and the like at architectural openings in structures, and for other applications. 10, 2013.
