Adjustable tension-mounted curved rod assembly

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.
