Adjustable tension-mounted curved rod assembly
View Patent ↗An adjustable rod assembly includes first and second tubes having first and second arcuate portions, third and fourth tubes of generally straight configurations, first and second end supports, and a tension rod mechanism secured within the third tube. The first tube has a first end, a second opposing end, and a planar surface extending from the second end toward the first end. The first tube is telescopingly received within the third tube and the second tube. The third tube is rotatable relative to the first tube and is rotatably secured within the fourth tube. The fourth tube is secured to the first end support and the second tube is secured to the second end support. The tension rod mechanism rotates with the third tube and has a threaded portion configured to extend from an interior of the third tube to an interior of the first tube.
1. An adjustable rod assembly comprising:
a first arcuate tube having a first end, a second opposing end, and at least one planar surface extending from at least the second end of the first arcuate tube toward the first end of the first arcuate tube;
a second arcuate tube, the second end of the first arcuate tube being telescopingly received within the second arcuate tube;
a third tube of a generally straight configuration, the first end of the first arcuate tube being telescopingly received within the third tube; and
a fourth tube of a generally straight configuration, the third tube being rotatable relative to the first arcuate tube and being rotatably secured within the fourth tube;
a first end support configured to be removably mounted to a first support surface and a second end support configured to be removably mounted to a second support surface, the fourth tube being secured to the first end support and the second arcuate tube being secured to the second end support; and
a tension rod mechanism fixedly secured within the third tube for rotational movement therewith, the tension rod mechanism having a threaded portion configured to extend into an interior of the first arcuate tube, the tension rod mechanism being configured to generate a compressive force which is exerted by the adjustable rod assembly upon the first and second support surfaces.
2. The adjustable rod assembly of claim 1 , wherein the first arcuate tube has a substantially D-shaped cross-section.
3. The adjustable rod assembly of claim 2 , wherein the second arcuate tube has a substantially circular cross-section.
4. The adjustable rod assembly of claim 1 , wherein the fourth tube is pivotably secured to the first end support and the second arcuate tube is pivotably secured to the second end support.
5. The adjustable rod assembly of claim 1 , wherein the interior of the first arcuate tube includes a threaded bushing configured to threadingly engage the threaded portion of the tension rod mechanism.
6. The adjustable rod assembly of claim 5 , wherein the threaded bushing includes an exterior planar surface which engages the at least one planar surface of the first arcuate tube.
7. The adjustable rod assembly of claim 1 , wherein rotation of the third tube in a first direction about a longitudinal axis of the third tube causes the first arcuate tube and fourth tube to move away from each other and wherein rotation of the third tube in a second opposite direction about the longitudinal axis of the third tube causes the first arcuate tube and fourth tube to move toward each other.
8. The adjustable rod assembly of claim 1 , wherein the second arcuate tube includes at least one aperture of a size sufficient to allow a fastener to pass therethrough.
9. The adjustable rod assembly of claim 1 , wherein at least a part of the threaded portion of the tension rod mechanism is flexible.
10. The adjustable rod assembly of claim 1 , further comprising a cover removably secured to each of the first and second end supports, each cover having an aperture configured to receive a fastener therethrough.
11. The adjustable rod assembly of claim 10 , wherein each of the first and second end supports includes a base wall having at least one indentation formed therein, the indentation including a cavity and an angled wall, the fastener passing through the aperture of the cover and engaging the angled wall of the indentation in an assembled position of the adjustable rod assembly.
12. The adjustable rod assembly of claim 1 , wherein the tension rod mechanism comprises a connector fixedly secured with in the third tube and a pin which extends away from the threaded portion and engages an aperture formed in a wall of the fourth tube, such that the third tube is rotatably secured within the fourth tube.
