The subject matter described herein is directed to a hanger device used to suspend hanging materials, such as shower curtains, drapery, or other sheet-like materials, from a horizontally suspended rod to provide a barrier or for decorative purposes. More particularly, the invention is directed to a unique, novel, and nonobvious hanger device with decorative covers used on a single elongated rod member to suspend one or more hanging materials from two independent extending members which can be viewed from two opposing sides.
BACKGROUND OF THE INVENTION
Hanger devices for hanging shower curtains, drapery and other hanging materials are known. Such known hanger devices include curtain rings, single hooks and double hooks. Curtain rings are often difficult to engage and disengage from the curtains and the rod, they are manufactured in limited design styles, and they often only provide a single curtain engaging member from which it is difficult to hang, access, remove and/or replace two or more curtains or hanging materials. Single hooks require a user to remove the hook from the rod each time a curtain is removed or replaced, the user is potentially required to remove and replace both curtains when accessing a single curtain, and the curtains often slip off of the hook when the hooks are moved horizontally across the rod. Double hooks generally do not have fixed or removable decorative covers and do not have two positive and opposing front views. In addition, while most curtain rod assemblies are adequately functional, unsightly metallic or plastic rods often detract from maintaining a decorative appearance. Replacing an existing rod may not be permitted such as in rental apartments or may be difficult, costly, and require skilled labor, such as drilling in tile, backer board, and hard to reach places. Rod covers exist in the prior art but the covers often hinder the movement of the rings along the rod and are often costly and time consuming to install.
Accordingly, there is a need for a new and improved hanger device with decorative covers that does not have the problems associated with known hanger devices.

DETAILED DESCRIPTION OF THE INVENTION
The invention is directed to a unique, novel, and nonobvious hanger device with decorative covers used to suspend one or more hanging materials, such as drapes, shower curtains, or other sheet-like materials from a horizontally suspended rod to provide a barrier or for decorative purposes. The invention relates to a hanger device used on a single elongated rod member to suspend one or more hanging materials from two independent extending members which can be viewed from two opposing sides.
With reference now to the drawings, a first version or embodiment of the hanger device of the invention is shown in FIGS. 1-11. FIG. 1 is a perspective view of a first version of a hanger device 10 of the invention. The hanger device 10 comprises a body portion 12 having a first end 14, a second end 16, and a top central portion 18. The body portion 12 preferably has a generally circular configuration with an inside diameter that is of a sufficient size for encircling a portion 20 of an elongated rod member 22 when the hanger device 10 is coupled to the rod member and the rod member is suspended in a horizontal position, as shown in FIG. 11. FIG. 11 is perspective view of a plurality of hanger devices 10 that are suspending a plurality of hanging materials 24 such as curtains. The body portion may be in the configuration of a complete circle, a semi-circle, an incomplete circle, or another suitable geometric shape. The body portion is configured and dimensioned to extend cooperatively around an elongated rod member. Mounting of the hanger device on a rod is accomplished by applying minimal force to the base of the hanger to widen its generally circular shaped opening, enabling the hanger device to attach or couple onto the rod. Once in place on the rod, the body portion of the hanger device then regains its original shape. As shown in FIGS. 16-17, the body portion of any of the versions of the hanger device of the invention may include a plurality of movable ball bearings or beads 26 (FIG. 16) or fixed ball bearings or beads 28 (FIG. 17) coupled to the body portion. Preferably, each of the ball bearings or beads has a central hole through which the body portion of the hanger device is inserted or the ball bearings may be embedded in recesses within the inner diameter of the body portion.
