  • Patent number: 7204031
    Abstract: The telescoping T-square has a crossbar or cross-member and an extendable shaft or leg. The cross-member is a relatively short bar having a pair of parallel runners longitudinally extending across the length of one surface of the bar and a slot defined through the bar between the runners that extends from the center of the bar laterally towards one of the ends of the bar. The leg has a tubular, hollow proximal rod removably attached to the cross-member, and at least one telescoping distal rod slidably disposed in the proximal rod, with detent buttons locking the rods together at selected intervals. One end of the proximal rod has transverse grooves or channels defined therein slidably receiving the runners and a threaded stud extending therefrom that is slidable in the slot defined in the cross-member. A knob engages the stud to temporarily lock the cross-member and leg in fixed relation.
