Abstract
A tension rod has an outer shaft slidably receiving an inner shaft. A tension mechanism includes a partially threaded rod with a threaded portion. A first end extends from the threaded portion and is adapted for fixing to an inner surface of the inner shaft; a second end has a tapered body with a greater transverse dimension closer to the second end. A wedge has a slot and an inner surface in facing sliding engagement with the tapered body between a nut threadedly engaged with the threaded portion and the second end. The nut is rotationally fixed to the outer shaft. Upon relative rotation of the inner and outer shafts, the nut moves along the threaded portion toward the second end, the wedge abutting and moving with the nut. The wedge contacts the tapered body, expands radially, and contacts the inner surface of the outer shaft, locking the shafts together.
