FIELD OF THE INVENTION 
       [0001]    The present invention relates to an improved shower curtain rod and fixture. More particularly, the invention encompasses a shower curtain rod that can be used safely and securely in the motel/hotel industry. This invention further includes inventive features, such as, a shower rod that has substantially straight ends and a portion that is visibly curved to allow for “elbow room” for upper body movement of a person using a shower, a non-twist or non-sagging feature that prevents the inventive shower curtain rod from rotating or twisting after it has been installed, a fixture to securely and safely secure the inventive shower curtain rod to a surface, such as a wall, to name a few. 
       BACKGROUND INFORMATION 
       [0002]    In the construction of most bathrooms, it is common to position a shower head or shower nozzle which is mounted on the wall in an enclosure above a bath tub or a shower stall to thereby provide the option of a shower for the resident or the guest using the bathroom facility. In defining such enclosures, splashing water out of the enclosure is limited by the use of a sliding door, typically a translucent plastic or shatter proof glass, or more conveniently, a shower curtain. The shower curtain is ordinarily constructed and arranged to drape loosely from a set of eyelets or curtain rings which slide along the curtain rod. A set of such rings is normally mounted slidably on the shower curtain rod which is positioned normally at the height of the sprinkler head or other nozzle. The shower curtain is draped in the bath tub below or around a shower stall so that water is not splashed out of the bath tub or the shower stall. Because the bath tub is below the shower nozzle, the bath tub also functions to collect water which drains from the bath tub during the shower. 
         [0003]    Many bath tubs and shower stalls are constructed in a rectangular manner having one side exposed while the other three sides have a wall or an enclosure. For such straight side bath tubs a straight shower rod can be easily positioned above the straight edge. A shower curtain can then be secured to the straight shower rod so as to prevent the splashing of the water to an area outside of the tub or the shower stall and also to direct the water from a shower head towards a shower drain. 
         [0004]    It is well know in the art to provide a shower curtain rod which is shaped and profiled to fit above and in cooperation with a particular type shower or tub construction. These types of shower curtain rods are intended to be used to support a shower curtain so as to prevent water from splashing out of the enclosure bordered by the shower curtain as the curtain is draped into a bath tub below the curtain rod. 
         [0005]    A curved shower rod is particularly adapted for use with an oval or an elliptical shaped bath tub so as to follow the contours of the oval or the elliptical shaped bath tub so as to direct the water coming from a shower head towards the drain or just to provide an extra “elbow room” to the user or guest. 
         [0006]    U.S. Pat. No. 4,754,504 (Cellini), the disclosure of which is incorporated herein by reference, discloses a shower enlarger where the shower area can be enlarged to provide a greater stall space for upper body movement of a person using the shower. The one-piece curtain rod has an offset medial section for outwardly displacing an upper area of a shower curtain to allow for greater space in shower stall for upper body movement while showering. The offset medial section also includes a pair of angular curtain rod sections that extend in diverging relation away from opposite ends of the offset medial section. 
         [0007]    U.S. Pat. No. 5,022,104, (Miller), the disclosure of which is incorporated herein by reference, discloses a shower curtain support for a straight sided bath tub where the shower rod is provided with a central straight portion having a length approximately equal to that of the bath tub and which also includes offset end rod portions which enable connection with the tile wall which surrounds the bath tub. In this construction, the bath tub is positioned below the shower curtain rod so that the shower curtain can drape in the tub. The overhead shower rod has a straight length portion which approximately conforms to the length or profile of the bath tub when viewed from above. 
         [0008]    U.S. Pat. No. 6,216,287 (Wise), the disclosure of which is incorporated herein by reference, discloses a shower curtain rod having two end portions with angled fittings to enable the shower curtain rod to be attached between a pair of parallel walls at a bath tub enclosure. The shower curtain rod is constructed with a central portion curving to follow the edge or profile of an oval or elliptical bath tub. This curving central portion enables the shower curtain to hang into the bath tub. When positioned above the bath tub, the shower curtain rod is particularly useful to deflect splashed water into the tub by enabling a user to simply slide the shower curtain along the length of the shower curtain rod so that it hangs into the tub therebelow. 
         [0009]    U.S. Pat. No. 7,076,815 (Orpilla), the disclosure of which is incorporated herein by reference, discloses a curved shower curtain rod having two end portions that are bent at 70 degrees. The curved shower curtain rod is straight in the middle but curved at both ends. The middle of the curtain rod is still along the outside edge of the tub, but the ends curve towards inside to the middle of the tub. 
         [0010]    However, one of the problems that exists with the present shower rods is that they twist and/or sag and/or rotate thus creating an unsafe environment and this movement of the curved shower rod also weakens the associated fixtures. This is primarily due to the fact that the center of gravity of the curved shower rod is at a location which forces the central curved portion to move or rotate or sag down towards the earth. 
         [0011]    Thus, it is clear that the shower rods and shower rod fixtures of the prior art have a problem that needs an inventive solution. These and other problems are overcome by the present invention.

However, at the other end  31 , which is the no-hole end  32 , a securing device  20 , such as a set-screw  20 , is used to securely secure the other end  31 , or the no-hole end  32 , of the inventive shower rod  30 , to the inventive shower rod fixture  23 . 
         [0051]    The shower curtain rod  30 , when viewed from above, preferably has a curving portion  39 . The curving portion  39 , of the instant inventive shower rod may or may not conform to the curvature of a corresponding bath tub. The bath tub could be of any shape or size and similarly the bath or shower stall could be of any shape or size, however with the inventive straight and curved shower rod one would still get more “elbow” room for upper body movement. 
         [0052]    For some applications it would be preferred that the shower curtain rod  30 , conforms with the curvature of a correspondingly curved bath tub. The bath tub or Jacuzzi many be of an oval or it may be elliptical in shape, and thus the shower rod  30 , has at least a central curved portion  39 , which matches that curvature and is located the requisite distance above the bath tub (not shown) so that the shower curtain, (not shown) hangs loosely from the shower rod  30 , on a set of rod hangers, drapes into the tub and to prevent splashed water from escaping from the bath tub around the ends of the curtain. 
         [0053]    It is preferred that the shower curtain rod  30 , is a hollow tube  35 , having an opening  33 . However, for some applications the shower curtain rod  30 , could be made from a light weight solid material which is inexpensive to produce but which can withstand the normal weight of a shower curtain (not shown). Similarly, the shower curtain rod  30 , could be made from a composite material. For some applications the shower curtain rod  30 , could be made from a material that is strong on the outside but relatively soft and light weight on the inside, such as for example, the outside shell  35 , could be of a metallic or a plastic material, while the inside or inner core  37 , could be of a light weight material which is well known in the art, such as, for example, a Styrofoam material or a light-weight composite material, to name a few. 
         [0054]    The securing device  20 , could be selected from a group comprising, a screw, a bolt, a set-crew, a rivet, a pin, to name a few. 
         [0055]    The shower rod fixture or flange  23 , is preferably made from a material, such as for example stainless steel, rustproof zinc, nickel, chrome, plastic, rubber, metallic material, composite material, to name a few. 
         [0056]    The shower rod  30 , is preferably made from a material, such as for example stainless steel, rustproof zinc, nickel, chrome, plastic, rubber, metallic material, composite material, to name a few. 
         [0057]    For some applications, it is preferred that the central portion  39 , is between about  20  percent to about 80 percent of the total length of the straight and curved shower curtain rod  30 . 
         [0058]    For some applications the straight and curved shower curtain rod  30  would be about 60 inches long, with a one inch outer diameter, and wherein the central curved portion  39 , has a bow of between about 4 inches to about 8 inches in the middle, and the straight end portions  31 , are between about 3 inches to about 9 inches in length. However, it is preferred that the straight and curved shower curtain rod  30 , is between about 36 inches to about 78 inches long, with about a diameter of between about one half inch to about one inch, and wherein the central curved portion  39 , has a bow in the middle of between about 4 inches to about 8 inches, and the straight end portions  31 , are between about 4 inches to about 8 inches in length. 
         [0059]    While the present invention has been particularly described in conjunction with a specific preferred embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
