<p>A tension rod positioning apparatus and method including a shaped threaded rod (20) inserted into a shaped threaded hole (22, 56) on an engagement collar (16). When the shaped rod (20) and shaped hole (22, 56) are aligned, the rod (20) may be freely positioned within the collar (16). When the shaped rod (20) is inserted into the collar (16) and turned, the rod (20) engages and turns the engagement collar (16). The engagement collar (16) includes an external thread (29) sized to fit an internal thread (23) on a clamp base (52). The rod (20) may be inserted and then turned to both engage the engagement collar (16) and increase the clamping pressure. The shaped rod (20) may be turned in the opposite direction to loosen the clamping pressure and disengage the engagement collar (16). Once the rod (20) and collar (16) have been disengaged by aligning the shaped rod (20) and shaped hole (22, 56), the rod (20) may be freely moved within the engagement collar (16) to reposition the clamp (10) for the next operation.</p> |
