Description:
FIELD OF THE DISCLOSURE 
     Reflective yard signs. 
     PRIORITY 
     This application does not claim the priority date of any other applications. 
     BACKGROUND OF THE INVENTION 
     Yard signs are commonly used to convey information. They may advertise that a home is for sale, display an address, identify a preference for a sports team, show support for a political candidate, or convey numerous other written or visual representations. Such signs are often constructed of plastic, metal, or wood and usually include a message printed on a flat display surface. Yard signs may also be constructed of reflective materials. 
     Reflective yard signs are often small, monochromatic round reflectors mounted on a stake. They have many uses, such as marking the ends of a driveway so the driveway may be easily seen at night. The round reflective yard signs are inexpensive to manufacture, but they do not give the user the ability to select their own message for display or manipulate the sign to display interchangeable messages. Noble (U.S. Pat. No. 6,845,580) discloses a prior art reflective yard sign with multiple layers permanently secured together with an adhesive. Noble&#39;s adhesive construction is a drawback because it prevents a user from being able to use one sign to display multiple, interchangeable messages, and it prevents a user from being able to change the sign&#39;s appearance by utilizing interchangeable reflectors. Additionally, adhesive construction is disadvantageous because the adhesive is likely to degrade over time, obscuring images on the sign and rendering the sign ineffective. Accordingly, there is a need for a reflective yard sign that allows a user to select their own messages and give a user the option of choosing different interchangeable messages and reflectors. 
     SUMMARY OF THE INVENTION 
     The present invention is an improved reflective yard sign that solves problems associated with the prior art by allowing users to choose among different interchangeable messages and reflectors. According to one embodiment, the retro-reflective graphic display comprises interchangeable components that are assembled to create a two sided reflective yard sign. In this embodiment, the innermost component is a center backing member. Front and back interchangeable reflectors are placed on either side of the center backing member. The reflectors are formed of a material that incorporates retro-reflective cube corners on one side of the reflectors. 
     Front and back graphics are placed on the outer side of the interchangeable reflectors. In one embodiment, the graphics comprise images incorporated on the surface of a transparent material. The images may be changed by inserting different graphics, and any letter, numeral, symbol, or other type of image may be used. In other embodiments, the graphics may comprise images that are incorporated directly on the front side of the reflectors. 
     Front and back clear lenses are placed on the outer sides of the graphics. Front and back covers are placed on the outer sides of the lenses. The covers contain an aperture through which the other components can be viewed. The inner edges of the covers contain a means for fastening the covers together, and the lenses, graphics, reflectors, and backing member are retained within the assembled covers in a non-adhesive manner. 
     The retro-reflective graphic display may be manufactured in a number of shapes, including, but not limited to a circle, rectangle, triangle, or pentagon. The display could similarly be made in the shape of a football, cross, waving flag, tractor, or virtually any other shape. The retro-reflective graphic display may incorporate a number of means for mounting the display. The mounting means include but are not limited to an aperture for receiving a stake, an aperture for receiving a fastener such as a nail or screw, or an adhesive. 
     In one embodiment, the retro-reflective graphic display may be one sided. The back cover of a one sided display is molded to form the back portion of a frame and does not contain an aperture. An interchangeable reflector is placed inside the back cover, a graphic is placed in front of the reflector, a lens is placed over the graphic, and then a front cover is fastened to the rear cover to retain the lens, graphic, and reflector. Like the two sided version, the front cover forms an aperture through which the lens, graphic, and reflector may be seen. 
     Accordingly, the retro-reflective graphic display provides an improved reflective yard sign that allows a user to select their own message and gives a user the option of choosing different interchangeable messages.

     DETAILED DESCRIPTION 
       FIG. 1  is a perspective view of a disassembled retro-reflective graphic display  1 . In this embodiment, the display  1  is two sided and is round in shape. The innermost component of the retro-reflective graphic display  1  is a center backing member  2 . The center backing member  2  is composed of high impact polystyrene in this embodiment, but other suitable materials may be used. 
     Interchangeable reflectors  3  are placed on both sides of the center backing member  2 . The reflectors  3  are made of a reflective material with a multiplicity of retro-reflective cube corners formed on the inner sides of the reflectors  3 . Retro-reflective cube corners are comprised of three approximately mutually perpendicular optical faces that cooperate to retroreflect incident light back towards the viewer. The cube corners are well known in the art and have often been used to construct roadway and automotive reflectors. The interchangeable reflectors  3  may be a number of different colors, and a user may swap out the reflectors  3  for a color of their choosing. The interchangeable reflectors  3  may be composed of acrylic, but other suitable materials may also be used. 
     Front and back graphics  4  are placed on the outer side of the interchangeable reflectors  3 . In this embodiment, the graphics  4  include images  5  that are incorporated onto the surface of a transparent material. The images  5  are represented by the letter “A” in this example, but any image, character, or numeral may be used. The graphics  4  in this embodiment are interchangeable. In other embodiments, the graphics  4  may be comprised of images  5  incorporated directly onto the surface of the reflectors  3 . 
     Front and back clear lenses  6  are placed on the outer side of the graphics  4 . The lenses  6  in one embodiment are composed of clear high impact polystyrene, but other optically transmissive materials may be used.
