Abstract:
A display assembly may be fitted with display advertisements. The assembly may be affixed to pre-existing cooler doors, including those that do not permit a bracket to completely surround it.

Description:
This application claims the benefit of U.S. Provisional Application No. 61/502,432, filed Jun. 29, 2011. 
    
    
     TECHNICAL FIELD OF THE INVENTION 
     The present invention relates generally to display advertising surfaces, and more specifically to assemblies that are added to or combined with pre-existing door handles. 
     BACKGROUND OF THE INVENTION 
     The placing of display advertisements near consumer shelf space is generally known. Of late, retailers and advertisers have placed display ads on surfaces associated with the door handles of refrigeration coolers. For example, U.S. Pat. No. 7,383,654 describes an assembly that replaces entirely a cooler door handle, such as on the cooler aisle of a grocery or convenience store. On the assembly, there is a surface within a cavity that allows the interchanging of graphic displays, including advertisements. The assembly is mounted directly to the door itself after the pre-existing handle is removed. 
     There are several advantages to these kinds of assemblies. They allow ads to receive consumer attention at or near the moment of purchase. They also allow for quick and easy advertisement changes. 
     What is needed is an assembly that does not require replacement of a door handle. What is also needed is a capacity to mate a display advertising surface with the wide variety of legacy door handles that currently exist at retail point of sale locations. What is further needed is a capacity to mate a display advertising surface with a door handle type that does not permit a bracket to surround its axis for the full three hundred sixty degrees. 
     SUMMARY OF THE INVENTION 
     The present invention eliminates the drawbacks of preexisting assemblies. In the embodiments described below, the invention includes bracket clips designed and shaped for pre-existing legacy cooler door handles. In three of the embodiments below, the bracket clips are for handles that allow a full three hundred sixty degree wrap-around. In a fourth embodiment, the bracket clip is for handles that do not permit such a wrap-around, for example a full-length L-bar. Other features and advantages of the present invention will become apparent from the detailed description below.

     DETAILED DESCRIPTION 
     The present invention is described below in its various embodiments and configurations. The description is not intended to be limiting, and instead the appended claims alone describe the metes and bounds of the rights under the present invention. 
       FIG. 1  shows an elevation view of the front of a fully assembled display assembly  10 , minus any display insert. There is a top end cap  20  and a bottom end cap  30  inserted into the respective top and bottom of the display assembly. The display assembly  10  is generally rectangular, and in this embodiment has a convexly curved surface. Along each side of the curved surface is a lip flange  40 . When one of the end caps is removed (e.g., the top), a display ad and its optional clear flexible cover (e.g., of thin transparent plexiglass) may be inserted into the display assembly. The end cap is then replaced. The display ad is thereby held in by the lip flange  40  and the respective end caps  20 ,  30 .  FIG. 1  also shows apertures  50  for receiving fastening screws  55  for the various kinds of brackets, to be described below. 
       FIG. 2  is an elevation view of the rear of a fully assembled display assembly  10  using a first bracket type to surround a first type of legacy handle (namely, certain cooler handles by manufacturers Anthony and Ardco). The specific brackets  60  for this embodiment are more fully disclosed in  FIG. 9 , and are seen to be generally flat, with a J-shaped slot-fitting end  65 . Opposite the slot-fitting end  65  is an aperture for receiving the above-mentioned fastening screw  55 . 
       FIG. 3  is an elevation view of the rear of a fully assembled display assembly  10  using a second bracket type to surround a second type of legacy handle (namely, certain cooler handles by manufacturer Anthony, particularly more recent models). The specific brackets  70  for this embodiment are more fully disclosed in  FIG. 10 , and are seen to form a generally rectangular open shape, with a slot-fitting end  75 . Again, opposite the slot-fitting end  75  is an aperture for receiving the above-mentioned fastening screw  55 . 
       FIG. 4  is an elevation view of the rear of a fully assembled display assembly  10  using a third bracket type to surround a third type of legacy handle (namely, certain cooler handles by manufacturer Hussman). The specific brackets  80  for this embodiment are more fully disclosed in  FIG. 11 , and are seen to form a generally rounded, open C-shape, with a slot-fitting end  85 . Again, opposite the slot-fitting end  85  is an aperture for receiving the above-mentioned fastening screw  55 . 
       FIGS. 5 ,  6  and  7  show perspective views depicting how the brackets  60 ,  70 ,  80  are attached to the display assemblies  10  of the present embodiments. The apertures on the front of the display assembly are larger than the ones on the back, such that a fastening screw  55  will pass completely through the front into the inner volume, so that its head rests flush against the back aperture. Then the respective bracket  60 ,  70 ,  80  is placed over the screw body, and the fastening nut  57  installed. In this way, a retailer or advertiser may easily install the display assembly  10  around the legacy door handle using conventional tools (such as a screwdriver and a wrench or needle pliers). Once installed, a consumer would pull on the display assembly  10  to open a cooler door, usually while looking right at it and its inserted-ad. 
       FIG. 8  shows a side view of the display assembly  10 , indicating where the slots  15  are for receiving the slot-fitting end  65 ,  75 ,  85  of the various brackets. It will be apparent that to affix the brackets  60 ,  70 ,  80 , the slot-fitting end  65 ,  75 ,  85  is inserted into its slot, and then the screw  55  and bolt  57  are connected from the front to complete the connection. For the embodiments described so far, the final assembly will completely surround the legacy door handle. 
       FIG. 12  is an elevation view of a different type of compatible bracket  90 , for use as a clamp where a cooler door handle cannot be completely surrounded. It is assembled in the same way as the above-mentioned brackets, but results in an open tension-clamp, having bulbous ends. The embodiment of  FIG. 12  is particularly useful for cooler door handle types like the full-length handles that may exist on the Anthony Model 101 cooler. Such handles are an L-shaped member running from top to bottom of the door, and thus do not allow brackets to completely surround them. 
       FIGS. 13 and 14  show, respectively, side and top views of the respective end caps (top  20  and bottom  30 ). These end caps  20 ,  30  are shaped asymmetrically to generally match the curved, asymmetrical cross section of the display assembly volume. They are inserted using a friction-fit. They each have two ends—distal  22 ,  32  from the bracket side, and proximal  24 ,  34  to the bracket side. Each end has projecting fin planes  25 ,  35  sized to allow a friction fit into the display assembly. Between the fin planes is an opening  27 ,  37  to allow passage into the volume of the display assembly, without interfering with a structural bar within such volume. The end caps may optionally be expanded in length, and fitted with electronics to provide battery-powered lighting displays, and/or sounds. Such lighting and sounds may be activated by proximity sensors, or by any other known means. In this way, the end caps may contribute even greater attention-attraction to the display assembly of the present invention. 
       FIGS. 15 and 16  show, respectively, top and bottom views of the fully assembled display assembly  10 . The asymmetry of the cross section, and its curvature from the proximal to the distal ends, are clearly indicated. 
       FIG. 17  shows an elevation view of the front of the fully assembled display assembly  10  of the present invention, now equipped with an actual display ad. The display ad may be removed and replaced as desired by removing one of the end caps, and sliding the graphic material in and out over the front curved surface and under the lip flange. It will be appreciated that insertion of a display advertisement blocks any view of the screw apertures and screw head. 
     While the invention has been described with particular reference to specific embodiments, it will be apparent to those skilled in the art that the same principles may be used in similar arrangements. The invention is not limited to the precise structures described. Various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the claims below.
