Claim:
A roller case assembly for use with a support rod comprising: a roller sleeve having a first end and a second end; a primary keeper having a passage for receiving the support rod, and having an expandable gap for securing the support rod; a secondary keeper having a passage for receiving the support rod, and having an expandable gap for securing the support rod; a primary hub having an inner hub, an outer hub, and a cavity; a secondary hub having an inner hub, an outer hub, and a cavity; and a tube connected between the primary inner hub and the secondary inner hub; wherein the cavity of the primary hub receives and allows rotational movement of the primary keeper, and has an inner aperture and an outer aperture, said outer aperture defined by a primary annular tab having a diameter slightly less than the diameter of the inner aperture, said primary annular tab facilitating rotational movement of the primary keeper; wherein the primary keeper has slip ridges to facilitate rotational movement of said primary keeper within the cavity of the primary hub; wherein the cavity of the secondary hub receives and allows rotational movement of the secondary keeper, and has an inner aperture and an outer aperture, said outer aperture defined by a secondary annular tab having a diameter slightly less than the diameter of the inner aperture, said secondary annular tab facilitating rotational movement of the secondary keeper; wherein the secondary keeper has slip ridges to facilitate rotational movement of said secondary keeper within the cavity of the secondary hub; wherein the outer hub of the primary hub is connected to the first end of the roller sleeve; wherein the outer hub of the secondary hub is connected to the second end of the roller sleeve; and wherein the primary keeper has a joined slit membrane for maintaining a substantially constant degree of tension on the support rod, and the secondary keeper has a joined slit membrane for maintaining a substantially constant degree of tension on the support rod.
