An interlocking telescoping assembly includes an inner member (10) that slides lengthwise and rotates inside a bore extending through an outer member (12). An outer locking surface (26) of generally constant diameter extends along the length of the inner member. The tubular outer member has a short, fixed locking ring section (14) and an adjacent long tubular section (16) of greater inside diameter than the locking ring. The locking ring is integrally formed with the wall of the outer member and has an inside locking surface (18) of generally constant diameter. The inner and outer locking surfaces, in cross-section, each have opposite semi-circular curved sections each of slightly different radius of curvature to provide an improved locking function. Such an assembly avoids moving parts which reduce reliability and do not favor fiber glass fabrication. The assembly may find use as an adjustable filler for sailboats. |
