<p>A segmented bar having a longitudinal axis, a first bar section (12) slidably interengageable with a second section (14) under longitudinal axially displacement to move into and out of end to end abutting interlocking mating relation, each of said bar sections presenting corresponding longitudinally extending mating surface formations (20, 22, 24, 26) on opposite sides and corresponding longitudinally extending mating edge formations (28, 30, 32, 34) along opposite edges, each bar section terminating in an abutting end edge formation (60, 62) to be presented to the abutting end edge formation of the other of said bar sections when disposed in interlocking mating relation, the opposed surface formations (20, 22) of one of said sections (12) each including a locating recess (64, 66) therein and offset in relation to each other and each bounded by a portion of the extent of its adjacent abutting end edge formation (60), the opposed surface formations (24, 26) of the other of said sections (14) each including a mating projection (100, 102) for each of said locating recesses and likewise offset in relation to each other and each bounded by a portion of the extent of its adjacent abutting end edge formation (62), said opposed locating recesses and prolections being slidably interengageable in at least one longitudinal axially orientation thereof for longitudinal displacement of said bar sections into and out of end to end abutting interlocking mating relation. Said bar section when disposed in end to end abutting interlocking mating relation presents peripheral abutting end edge formations being offset longitudinally to one another. </p> |
