  • Patent number: 10995786
    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.

  • Patent number: 8960456
    Abstract: A tension rod mechanism for a tension rod having a second inner shaft slideably received by a first outer shaft and rotatable about a longitudinal axis of the tension rod. An expandable collar is threadingly engaged with a tapered first threaded shaft is configured to be received in the first outer shaft for rotational movement therewith and slidable axial movement relative thereto. A second attachment shaft fixedly connected to the tapered first threaded shaft is configured to be received in the second inner shaft for rotational and slidable axial movement therewith. When the expandable collar is in the first outer shaft and the second attachment shaft is fixedly received in the second inner shaft, a first rotation of the first outer shaft relative to the second inner shaft expands a diameter of the collar fixedly attaching the expandable collar to the first outer shaft for axial movement therewith.

  • Patent number: 8851305
    Abstract: A tension rod mechanism for a tension rod having a first outer shaft with a second inner shaft slideable therein has a unidirectional slip-lock configured to be received in the first outer shaft for rotational movement therewith and unidirectional slidable axial movement relative thereto. A threaded shaft is fixedly connected to the unidirectional slip-lock. A collar is threadingly engaged with the threaded shaft and configured to be fixedly received in the second inner shaft for movement therewith. When the unidirectional slip-lock is in the first outer shaft and the collar is fixedly received in the second inner shaft, slidable axial movement of the unidirectional slip-lock relative to the first outer shaft may occur only in an expansion direction A rotation of the first outer shaft relative to the second inner shaft increases the axial distance between the unidirectional slip-lock and the collar.

  • Patent number: 8827587
    Abstract: A tension rod mechanism for a tension rod having a first outer shaft with a second inner shaft slideable therein. A first collar receiveable in the first outer shaft of a tension rod for rotational movement therewith and slidable axial movement relative thereto threadingly engages a tapered first threaded shaft and is configured to apply a outwardly-directed radial force to the first outer shaft. A second collar fixedly receivable in the second inner shaft for movement therewith engages the second threaded shaft. A first rotation of the first outer shaft relative to the second inner shaft increases the outwardly-directed radial force applied by the first collar to the first outer shaft, and a second rotation in an opposite direction increases the axial distance between the first and second collars.
