CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to and the benefit of US. Provisional Application No. 61/439,606, filed on Feb. 4, 2011, which is incorporated in its entirety in this document by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    This invention relates to the field of display devices. More specifically, this invention relates to display devices that are attachable to a cord. 
       BACKGROUND OF INVENTION 
       [0003]    This application comprises a display device that uses several embodiments to display messages, objects, advertisements, slogans, sports teams, geographic areas, companies, countries, cities, pictures, vacation destinations, interests from popular culture, colors or any other area of interest the user may have. This application further comprises a method to attach a display area in the form of, for example and without limitation, a flag/ribbon/tag or bead to power cords. Examples of cords include but are not limited to lap top cords, tablet computer power cords, MP3 headphone cords, cell phone chargers, and mouse cords. The display device can be attached to cords that vary in size or shape. The display device provides a display surface that is visible to the user and other people while the electronic equipment is in use as well as allowing for the user and others to view the display device while it is being charged or not in use. It is contemplated that the increased use of electronic devices such as MP3 players, cell phones, laptops and the like has provided a unique opportunity to use the exposed surface of the power cords and headphones for the purpose of providing a display device. These cords typically are used for extended periods of time and are in plain sight of the user and others. Normally these cords are not hidden and have a prominent place in the daily life of the user. 
         [0004]    Examples of known display devices that attach directly to power cords are limited to technical flags used in the IT business for the purpose of writing routing numbers on cables. These are not meant to be viewed by the general public and have little visual appeal nor do they allow for creative expression or advertising. It is apparent that there is a need for a device that allows these messages or interests to be displayed and that has low manufacturing cost. The display device will have the ability to use a variety of different materials for the flag/tag/ribbon such as plastic or cloth and the use of a bead to convey the same message in a limitless source of shapes, sizes and colors. 
       SUMMARY OF THE INVENTION 
       [0005]    In accordance with the purposes of this invention, as embodied and broadly described herein, this invention, in one aspect, relates to a display device that is attachable to a cord. The display device, in one aspect, comprises a display surface and a notch or clip. The display device can be constructed of, for example, plastic, rubber or metal and the like. The notch or clip is sized for receiving a cord so that the display device id attachable to the cord and allows for the display surface to be presented in an appealing fashion. In one aspect, the display device can be formed in a variety of shapes and sizes. In another aspect, the display device comprises a hook and loop material to allow for selective attachment of the display device to the cord. In this aspect, the display device can be attached to many different sizes and shapes of cords. In another aspect, the display device can be constructed from a single type of material and can have the notch of the display device incorporated into the body of the display device. In this aspect, the notch can be formed in the display surface for the purpose of displaying an image directly on the display device. Alternatively, the display surface can be attached to the clip. It is contemplated that a display can be printed, painted, or attached to the display surface with a sticker or other adhesive. 
         [0006]    In one aspect, the display device can comprise a one-piece assembly. In this aspect, the display device can easily be manufactured in a fashion so that the display device requires no additional assembly. 
         [0007]    In another aspect, the display surface can be formed to represent any object or shape. For example, the display surface can be a square, rectangle, circle, oval, or other common shape. In other examples, the display surface can be formed into the shape of, for example and without limitation, a flag, decorative bead, company logo, a common object such as, but not limited to: a) objects from nature (animals, stars, trees, the Earth); b) company logos; c) items from popular culture (stars likeness, little kitty) etc.; d) man-made objects (car, guitars, any manufactured item of interest). As can be appreciated, there can be many variations on the shape of the display surface. 
         [0008]    In one aspect, at least a portion of the display device can be formed using a predetermined color or range of colors. A pink bead, for example, might be used to raise awareness of breast cancer and at the same time be used simply for the purpose of displaying the color pink. In this aspect, a message can be displayed on the display surface, in addition to the predetermined color of the display device to convey an additional message or idea. 
         [0009]    In one aspect, the display device can vary in size to accommodate the various sized cords to which it can be attached. The display device can securedly attach to the intended cord as well as display an image or message on the display surface. In another aspect, the display device can be attached to the cord to allow for the proper presentation of the display surface, so that the display surface is presented in a form that is easily viewed regardless of the material used to construct the display surface. 
         [0010]    In one aspect, the display surface of the display device comprises a flag, a tag, and/or a ribbon. In this aspect, the flag/tag/ribbon can be formed from a different material than other portions of the display device. In another aspect, an outer end of the display device can allow the attachment of the flag/tag/ribbon to a cord. The flag/tag/ribbon can be attached to a cord by at least one of gluing the tag in place, heat sealing, applying pressure to the display device or inserting a plastic or metal “tab” or by snapping/sliding the display area on the clip and the like. In a further aspect, a hook and loop fastener can be used to attach the display device to a cord. For example, the flag/tag/ribbon can be looped around the cord for the purpose of attaching a non-like-kind material as a display area. 
         [0011]    Additional advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

However, before the present apparatuses, systems, and/or methods are disclosed and described, it is to be understood that this invention is not limited to the specific apparatuses, systems, and/or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. 
         [0033]    As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a “clip” can include two or more such clips unless the context indicates otherwise. 
         [0034]    Ranges may be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. 
         [0035]    As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. 
         [0036]    Reference will now be made in detail to aspects of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like parts. 
         [0037]    A display device that is attachable to a cord is provided. Referring to  FIG. 1 , in one aspect, the display device  100  comprises a display surface  110  configured for displaying a message. As used herein, “displaying a message” can mean displaying a message, an idea, a logo, an image or the like, through the use of color, shape, text, figures and the like. In another aspect, at least one notch  120  can be defined in at least a portion of the display device. For example, if the display surface is substantially cylindrical or spherical, as illustrated in  FIG. 1 , the at least one notch can be defined in the display surface. In other examples, the display device can comprise a display surface  110  and a rear surface  115 . In this aspect, with reference to  FIG. 1.1 , the at least one notch can be defined in the rear surface of the display device. In still another aspect, an outer wall can extend between the display surface and the rear surface. In this aspect, the at least one notch  120  can be defined therein at least a portion of the outer wall. The at least one notch can be sized and or shaped to conform to an electrical cord  130 , such as, for example and without limitation, an electrical cord for a computer, an MP3 players, a cell phone, or a mouse. In another aspect, at least a portion of the at least one notch can be substantially circular when viewed in cross-section, though other shapes are contemplated. In use, described more fully below, the at least one notch can be sized and shaped for compressive and frictional attachment of the display device  100  to at least a portion of a cord  130 . 
         [0038]    The display device  100  can be formed from a material such as plastic, rubber, wood, metal, fabric and the like. In one aspect, the display device can be formed from a single piece of material (i.e., the display device can be a monolithic display device). In other aspects, at least a portion of the display device can be formed from a first material, and a portion of the display device  100  can be formed from a second, different material. 
         [0039]    In one aspect, it is contemplated that the display device  100  can be manufactured using an injection molding process. The shape, size and color of the display device  100  can vary. For example, the display device can be formed into the shape of a bead as in  FIG. 1 . In another example, the display device  100  can be formed so that the display surface  110  of the display device is substantially square, substantially rectangular, substantially oval, or football shaped, as illustrated in  FIG. 1.1 . Other examples of the shape of the display device  100  and/or the display surface include, but are not limited to, a religious symbol, a flag or other geometric shapes. However, it is contemplated that the display device  100  and/or the display surface can be formed into any size and/or shape. In still another example, at least a portion of the display surface can be substantially planar. 
         [0040]    After and/or during manufacturing of the display device  100 , a message or image can be positioned onto the display surface  110 . For example, a message or image can be printed or painted on the display surface to display an additional message such as a company name, a particular country, a sports team or any other message someone may desire. The message, in one aspect, can be simply a color and/or the message could glow in the dark. In another aspect, it is contemplated that the message can be formed on the display surface  110  during manufacture of the display surface. For example, the message could be molded into the display surface while the display surface itself is being molded. In still another aspect, the message can also be embroidered, engraved, and/or stamped onto the display surface. 
         [0041]    In use, the display device  100  can be selectively attached to the cord  130  by snapping the device onto the cord such that at least a portion of the notch  120  surrounds the cord. As discussed above, the notch and can be sized to attach the display device to a cords of predetermined thickness. The display device  100  can be selectively moved on the cord  130  or removed from the cord by pulling the display device  100  off the cord in order to move the display device to another location. In one aspect, if the desired effect is for the display device  100  to be able to slide up and down the cord  130 , the notch  120  of the display device can be sized large enough to allow the display device  100  to slide freely up and down the cord  130  while still being firmly attached to the cord. 
         [0042]    In one aspect, and as illustrated in FIGS.  2  and  2 . 1 , the at least one notch  220  of the display device can be defined between a pair of opposed arms  235  extending from the display device. If the display device is substantially cylindrical, as illustrated in  FIG. 2 , the pair of arms can form at least a portion of the display surface  210 . In another aspect, the pair of arms  235  can extend from the display surface  210  and/or the rear surface  215  of the display device, depending on the shape of the display device. For example, in the first illustration of  FIG. 2.1 , the pair of arms  235  extend from the display surface  210 , while in the second illustration, the pair of arms extend from the rear surface  215  of the display device  200 . The pair of arms can be sized so that the notch defined therebetween is configured for attachment to cords of predetermined thickness. 
         [0043]    In use, in this aspect, the display device  200  can be selectively attached to the cord  230  by snapping the device onto the cord such that at least a portion of the notch  220  surrounds the cord. In one aspect, when attaching the device to the cord, at least one arm of the pair of arms  235  can flex away from the opposed arm to allow for the cord to enter the notch. Upon the cord  230  entering the notch, the at least one arm can flex back to the original position, thereby securing the cord in the notch  220 . 
         [0044]    Referring now to  FIG. 3 , in one aspect, the at least one notch can comprise a plurality of notches  320 ,  325 . In another aspect, a first notch  320  of the plurality of notches can have a first size, and a second notch  325  of the plurality of notches can have a second size that is smaller than the first size. Thus, the first notch can be sized to attach the display device  300  to a cord  330  having a first diameter, and the second notch can be sized to attach the display device to a cord having a second diameter. However, it is also contemplated that the first notch and the second notch can have substantially the same size. 
         [0045]    In another aspect, and with reference to  FIG. 3.1 , the plurality of notches  320 ,  325  can be defined between the pair of arms  335  extending from the display device. In a further aspect, the second notch  325  can be defined in the display device  300  adjacent to the first notch  320 . In this aspect, if a cord has the second diameter, the cord can pass through the first notch and attach to the second notch. Alternatively, if a cord has the first diameter, the cord will not fit into the second notch  325  and can attach to the first notch  320 . 
         [0046]    In still another aspect, the at least one notch can comprise a notch having a varied size. With reference to  FIGS. 3.2  and  3 . 3 , a first end  322  of the notch  320  can have a first size, and the second end  324  of the notch can have a second size that is smaller than the first size. In this aspect, different sized cords  330 ,  332  can attach to a display device  300  without the need to manufacture the exact notch  320  to match the cord size. For example, a first cord  332  having a first diameter can be attached to the display device  300  by frictional engagement of at least a portion of the first end  322  of the notch  320  with the first cord, and a second cord  330  having a second diameter can be attached to the display device  300  by frictional engagement of at least a portion of the second end  324  of the notch  320  with the second cord. 
         [0047]    Referring now to  FIG. 4 , a display device  400  that is attachable to a cord  430  is provided. As previously discussed, the display device comprises a display surface  410  configured for displaying a message and at least one notch  420  defined in at least a portion of the display device. In one aspect, the at least one notch can be defined between a pair of extending arms  435 . As illustrated in FIGS.  4  and  4 . 1 , the display surface  410  of the device can be formed in the shape of a flag or any other shape having any other size. In one aspect, the display surface of FIGS.  4  and  4 . 1  can be larger than the display surface of, for example, the display device illustrated in  FIG. 1 . In another aspect, at least a portion of the display surface  410  can be substantially planar. This large, planar display surface  410  can be an easy-to-read surface area for displaying the desired message. 
         [0048]    The display device can be formed from a plurality of pieces that can be assembled together. Referring to  FIG. 5 , in one aspect, the display device  500  comprises a clip  518  and a display surface  510 . In another aspect, the at least one notch  520  can be defined in the clip, for example, between the pair of opposed arms  535  such that the clip is attachable to the cord  530 . In another aspect and as illustrated in  FIG. 5.1 , a groove  540  can be defined in the clip, the groove configured for attachment to a corresponding tongue  550  formed in a portion of the display surface  510 . In this aspect, the display surface  510  can be slid or snapped into the corresponding groove  540  of the clip  518  to form a display device  500 . In another aspect and as illustrated in  FIG. 5.2 , a slot  560  can be defined in the clip  518 , the slot configured for attachment to a corresponding tab  570  formed in a portion of the display surface  510 . In this aspect, the tab of the display surface  510  can be slid or snapped into the corresponding slot  560  of the clip  518  to form a display device  500 . The tab  570  and slot  560  can be sized for secure attachment of the two pieces. In still another aspect and as illustrated in  FIG. 5.3 , a gap  580  can be defined in the clip, the gap having a narrowing protrusion  582 . An indentation  590  can be defined in a portion of the display surface, the indentation configured for attachment to the protrusion formed in the clip  518 . In this aspect, the protrusion  582  of the clip can be slid or snapped into the corresponding indentation  590  of the display surface  510  to form a display device  500 . As before, the notch  520  of the display device can be selectively attached to a cord  530 , and a message or image can be displayed on the display surface. As can be appreciated, when attached to a cord, the clip  518  can remain on the cord while the display surface  510  can be selectively detached from the clip. Also, the clip  518  can be manufactured separately from the display surface  510 . 
         [0049]    Referring to  FIG. 6 , in one aspect, the display device  600  can be formed in the shape of a flag or tag and can comprise two or more separate types of material. For example, the clip  618  can be formed from a first material, such as plastic, and the display surface  610  can be formed from a second material, such as cloth or film. The method for assembling the display device  600  differs in this aspect because the different materials need to be joined before the display device is complete. This will allow for a more standard printing process on the display surface  610  of the display device  600 . The display surface  610  of the display device  600  can be manufactured similar to a patch or a team flag. In one aspect, the display surface can be formed from a cloth-like or film material and can be printed on directly and/or embroidered for a more detailed and interesting representation of the desired message. 
         [0050]    In another aspect, the display surface  610  of the display device can be manufactured separately than the clip  618 . For example, the flags/tags/ribbons can be manufactured in a fashion so they can be mass-produced. In one aspect, the display on the display surface  610  can also be printed in a continual fashion further reducing production costs. In another aspect, ribbons/tags/flags can be printed or stitched on a continual spool then attached to the display device and cut. In a further aspect, the flags and/or ribbons can be cut prior to being attached to the display device  600  depending on the type of equipment sourced for the manufacturing process. For example, it is contemplated that when using an injection molding process to produce a plurality of display devices, the display devices can be lined up with the non-like-kind display surface (flag/tag/ribbon) and then cut to the proper size. In another aspect, the flag/ribbon/tag and/or a bead can also be used to simply add color to the cord. 
         [0051]    In use, the display surface  610  can be attached to the clip thereby completing the display device  600 . Three methods that can be used to attach the display surface  610  to the clip  618  are shown in  FIG. 6.1 ,  FIG. 6.2  and  FIG. 6.3 . One benefit of using one or more of several methods of attaching the display surface to the clip  620  is to make sure with different materials that the connection can be made cost efficiently, have a clean look at the point of attachment and allow for variations in the type of material used to manufacture the display device  600 . For example, the display surface  610  can be attached to the clip  618  by gluing the flag directly to an outside edge of the clip as shown in  FIG. 6.1 . In another example, and as illustrated in  FIG. 6.2 , a groove  640  can be defined in the clip  618 , the groove configured for attachment to a corresponding tongue  650  attached to the display surface. In this aspect, the display surface  610  can be slid or snapped into the corresponding groove  640  of the clip  618  to form a display device  600 . In another example, as illustrated in  FIG. 6.3 , the display surface can be attached to the clip  618  by making an edge  670  of the display surface  610  thicker than other portions of the display surface by sealing the edge, folding it, or attaching other material to the edge  670 . This thicker edge can be inserted into a corresponding slot  660  defined in an outer edge of the clip  618 . In one aspect, upon insertion of the edge  670  into the slot  660  of the clip, the display surface can be sealed and/or glued into place. 
         [0052]    In one aspect and illustrated in FIGS.  7  and  7 . 1 , the display surface  710  can comprise a ribbon attachable to the clip  718  as discussed above. In this aspect, display surface  710  can be made in various shapes, colors and styles of a ribbon. In another aspect, the display device  700  can comprise a plurality of clips  718  and a display surface  710 , as illustrated in  FIG. 7.2 . In this aspect, the notch  720  of each clip can be attachable to the cord  730  and the ribbon display surface can extend between the two clips such that the display surface appears as a banner that runs along the cord  730 . Of course, the display surface  710  can be printed, painted and the like for enhancing the display purposes. 
         [0053]    With reference to  FIGS. 8 ,  8 . 1  and  8 . 2 , in one aspect, the display surface  810  can comprise a hook and loop fastener  840 .
