Abstract: We provide a tension assembly for a curtain rod, preferably a shower curtain rod. The assembly includes a tube and a plunger slidably disposed within the tube. Between the tube and the plunger is a biasing means such as a spring. The plunger includes opposite L-shaped grooves having a common axial section and opposite tangential section. The groove allows inclusion of a locking pin that is retained in the tube. The combination of the locking pin and the L-shaped grooves allows the plunger to be moved until the plunger compresses the spring, then the plunger is locked. When additional the curtain rod is put into place the plunger or rod may be rotated, releasing the plunger and allowing the spring to provide additional tension.

Abstract: Methods and apparatuses are described for providing a telescoping, load-supporting rod assembly. In one embodiment, the rod assembly may include a first portion, a second portion, a locking assembly, and a tension adjustment assembly. The locking assembly may include a threaded bolt, a cylindrical sleeve, a cylindrical locking portion, and at least two securing pins. The locking assembly may allow a user to adjust an overall length of the rod assembly by allowing the first and second portions to move with respect to each other. The rod assembly may also include a tension adjustment assembly which may include a tension adjusting spring, a tension adjusting cylindrical tube, a spring clip, at least two rivets, and at least two spacers. The tension adjustment assembly may allow a user to make small changes to the length of the rod assembly at one of the ends without moving the first or second portions with respect to each other.
