CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to the disclosure of U.S. Provisional Patent Application No. 60/889,889, entitled “ADJUSTABLE CARRIER,” filed Feb. 14, 2007 and U.S. Provisional Patent No. 60/945,841 entitled “ADJUSTABLE CARRIER WITH STRAPS” filed on Jun. 22, 2007. 
     
    
     FIELD OF THE DISCLOSURE 
       [0002]    This invention relates to a carrier designed to add additional carrying capacity to an existing carrying case of various sizes and shapes fitted with at least one handle. 
       BACKGROUND 
       [0003]    As is well known and understood, there exists the problem of having to carry, in addition to the standard briefcase, attache case, suitcase, overnight bag or musical instrument case, such items as a personal computer, electronic organizer and cellular phone—as well as binders, books or sheet music. Thus, and as will be appreciated, the current state of affairs typically requires the user to carry several cases each time, for each of these additional items, which makes transport extremely cumbersome and difficult, given the fact that only two hands are available for carrying everything. Oftentimes, as awkward as it may be, a user is forced to carry more than one case in each hand, or beyond even that, carrying some of them over the shoulder or around the neck. Having such a large number of cases, then, makes it difficult to keep track of all of them to prevent forgetting one or more and leaving them behind—or, for security reasons, makes it difficult to keep track of each case in preventing its theft. 
         [0004]    One obvious solution is to use a very large carrying case to carry all the items necessary. Whether this case is then carried about by hand, wheeled about, or pulled along on rollers, such a solution is not readily practical as it requires the user to remove the contents of his or her standard briefcase or musical instrument case as used on a daily basis, and place those items in the larger suitcase. This cumbersome large case often does not offer the same protection that a custom fitted laptop or musical instrument case provides. In like vein, the user may only need to supplement the capacity of the case slightly. 
         [0005]    The need to compliment the capacity of oddly shaped and sized musical instrument cases is of particular concern. Instrumental directors, parents and students are continually burdened with problems that are related to the transportation, storage and protection of music folders and related items which do not fit within the musical instrument case. Specifically, instrumental directors continually waste time dealing with music folders, sheet music and related items scattered around the rehearsal room floor and instrument storage rooms. Students continually waste time asking others if they have seen their music folder and/or related items and replacing torn or lost music. Students are continually burdened with transporting their music folder and related items to and from school and storing their music folder during transportation. The common solution students have to these problems is to simply cram their materials such as a music folder into their back packs or musical instrument cases. Due to these burdens, the students encounter torn music folders, torn music sheets or even damaged musical instruments. Parents continually waste time dealing with the clutter of music folders and related articles at home. As a result, parents must waste time trying to find their child&#39;s music folder and related articles at home and/or at school. Parents frequently encounter the expense of replacing damaged and lost materials. 
         [0006]    U.S. Pat. No. 6,012,557, issued to Derelanko, discloses a briefcase companion bag system. However, this invention does not allow the bag to compliment cases of different sizes and shapes. 
         [0007]    U.S. Pat. No. 6,637,563 B1, issued to Ruckh discloses a clear plastic case for moving through an airport. However, this invention does not allow the bag to compliment cases of different sizes and shapes. Moreover, the invention attaches to the briefcase&#39;s handle, via loops, which impedes easy access to the contents of the briefcase. 
         [0008]    U.S. Patent Application 2005/0233517, issued to Reid discloses an airport security pouch. However, this invention if attached to a briefcase handle using straps  24  and  26  would impede the user&#39;s use of the briefcase handle. 
         [0009]    U.S. Pat. No. 5,947,241, issued to Rausch discloses joinable, soft-side containers. However, this invention does not allow the bag to compliment cases of different sizes and shapes. 
         [0010]    U.S. Patent Application 2006/0088231 A1 discloses an enclosed, hangable, folding pouch with a closure. However, the invention is designed to wrap around a carry handle instead of lie over it. 
         [0011]    JP 20002259574 discloses a carrying case for mobile tools such as electronic notebooks and portable information terminal units. However, this invention does not seem to attach to a briefcase handle by a strap used to overlie on top of the handle. 
         [0012]    It would therefore be beneficial to all users, especially to instrumental directors, students and parents if there was a simple inexpensive solution to the transportation, storage and protection of music folders and related materials. It would also be beneficial if the solution to this problem had the ability to interchangeably accommodate the need of users carrying small cases such as a flute case as well as users carrying large and oddly shaped cases such as a tuba case. 
       SUMMARY OF THE DISCLOSURE 
       [0013]    As will become apparent from the following description, the present invention comprises a carrier which offers a solution to the problems faced by those wishing to supplement the carrying capacity of cases equipped with at least one handle. As will be seen, the carrier is arranged to be placed on cases of varying shapes and sizes equipped with at least one handle, such as a musical instrument case. The configuration of the present invention permits it to engage the handle yet lie in an orientation parallel to and against a major vertical side of the case in an orientation which protects the contents from damage. A translucent outer panel permits viewing of the contents without opening the auxiliary carrying device. Thus, this invention allows many items to be transported along with the musical instrument case, briefcase, attache case, etc. using just one hand while securing and protecting the contents thereof. Such a carrier will be seen to be securable to the briefcase, attache case, small suitcase, overnight bag, etc., to prevent loss of one, or the other, and allows the user to have all the items conveniently secured together, and at the same time deterring theft. 
         [0014]    As will become clear from the following description, the carrier can be constructed of a soft material such as a translucent plastic, leather, or nylon, allowing it to be stored inside of a larger case when not in use. The carrier can have a plurality of different compartments to allow a variety of different articles to be carried such as pencils or business cards in addition to documents. 
         [0015]    As will be described below, in a preferred embodiment of the present invention a “case” (understood to mean in the following description a standard briefcase, an attache case, a musical instrument case, a small suitcase, an overnight bag, of varying size and shape) of substantial thickness is utilized, having a carry handle and top, bottom, side and end walls. With it, the carrier is employed, also having top, bottom, side and end walls, to provide at least one carrying compartment for additional articles to be placed within. The carrier has attachment means adjustable to fit different thickness and shapes of the case with which it is used and may be moved from one case of one thickness to another case of different thickness. 
         [0016]    In one embodiment of the invention, a strap extends from the back of the carrier having a plurality of slots, each wide enough to overlie and accept the carry handle of a case when extended therethrough, while abutting one of the side walls of the carrier against one of the side walls of the case. In this embodiment the user inserts the handle through one of the slots to allow a customizable fit to accommodate cases of varying sizes and shapes. Once the user selects the appropriate slot to accommodate the shape and size of the case, the excess strap material can be trimmed and discarded. In the alternative, the excess may be folded underneath the active portion of the strap, and the end thereof extending back towards the carrier, with the end then secured against the carrier. In this embodiment, the carrier may be universally used with various cases of varying thicknesses. 
         [0017]    In another embodiment, a pair of straps extend from the back of the folder. Each strap is attached at or near the lower end of the back panel of the folder. The straps are constructed with a surface having a hook and loop material or other similar fastening material. At or near the top end of the back panel of the folder are loops intended to receive the straps. This embodiment allows the user to insert the straps through the loops before attaching the straps to the handle. This enables the back side of the folder to abut the side of a case of various sizes and shapes. The loops securely attach the carrier to the case and aide in positioning the backside of the carrier against one of the side walls of the case. Once the user attaches the hook and loop straps to the handle to accommodate the shape and size of the case, the excess strap material can be trimmed and discarded. 
         [0018]    The part of the carrier that will contain the articles can be configured for objects of various shapes or as a folder for flat objects such as papers or manuscripts. The carrier can be constructed with different designs selected for the bag and folder constructions which allows for a versatile customizable system, permitting a user to select between different types of available carrier dimensions that might meet various requirements. 
         [0019]    In one embodiment of the invention, the part of the carrier used to contain articles is a bag. The bag has at least one openable wall. A fastener on the openable wall secures the contents inside of the bag by hook and loop fastener, snap fastener, button, clasp or any other suitable fastener known to those skilled in the art. 
         [0020]    It is a major object of the carrier to transport and protect paper music sheets and related items in a folder that attaches to a musical instrument case of various shape and size. This is accomplished by use of a wide fastener strap having a plurality of slots extending transversely along the length of the strap. The plurality of slots allows the user to adjust the location of the carrier to a secure location against on side of the musical instrument cases of varying shapes and thicknesses. For larger instrument cases, the carrier strap is inserted through a loop that is located on the back of the carrier, which keeps the carrier adjacent to the side of the case thereby providing enhanced stability. 
         [0021]    In the above one embodiment of the invention, the folder is opened by a flap. The flap can be secured by a hook and loop fastener, zipper, snap, or any suitable method know to those skilled in the art. In another embodiment of the invention, the folder has expandable sides in the form of bellows or equivalents to accommodate articles of varying thickness.

       [0031]    Referring to the drawings, where like numerals indicate like parts, there is seen in  FIGS. 1-5 , a first embodiment of this invention.  FIG. 1  shows a perspective view of this embodiment installed on a case  30 . 
       DETAILED DESCRIPTION 
       [0032]      FIG. 2  shows carrier  11 , loop  16 , loop attachment  18 , flap  12 , the back side of the carrier  19 , strap  20 , strap attachment  22 , slits  24 , and handle cut outs  26 . Loop attachment  18  can secure loop  16  to back side  19  and strap attachment  22  can secure strap  20  to back side  19  by glue, heat sealing or any other method known to those skilled in the art. 
         [0033]      FIG. 1  shows carrier  11  attached to case  30  against side wall  31  by inserting handle  32  through handle cut outs  26  and slits  24  in strap  20 . Carrier  11  has front side  10 , back side  19  ( FIG. 2 ), closure flap  12 , fastener  14 , and sides of the carrier  27 . Carrier  11  is attached to case  30  using strap  20 . Handle  32  is inserted through one of a plurality of slits  24  and handle cut outs  26  on strap  20 . The choice of which of the slits and cut outs selected, in which handle  32  is to be inserted through depends on the size, shape and especially the thickness of the case to which carrier  11  is to be attached. Strap  20  is preferably inserted through loop  16  before the carrier is attached to case  30 . Loop  16  provides added stability to the back side  19  of carrier  11  especially when attached to larger or oddly shaped cases. It should be understood that in the process of attaching and manufacturing loop  16  to carrier  11 , loop  16  should be wide enough to allow strap  20  under it, but still keep the body of carrier  11  close to the case it is attached to in order to provide enhanced stability when used with large and/or oddly shaped cases. In the preferred embodiment, strap attachment  22  is mounted on the lower one third of the back side  19  in order to accommodate cases of various sizes and shapes. This permits the strap to extend directly to the case handle. However, to add stability, the strap usually is inserted through loop  16  to provide added stability as the strap  20  would then extend from the top portion of back side  19 . 
         [0034]    In one embodiment, flap  12  is constructed as an extension of back side  19  to project over front side  10 . This provides a means to secure the contents of carrier  11  inside the carrier. Moreover, flap  12  provides protection from the elements such as rain. On the inside cover of flap  12  and the front side  10 , of carrier  11  is at least one fastener  14 . Fastener can be of snap, hook and loop, clasp or any other fastener known to those skilled in the art. The sides of the carrier  27  can be expandible to accommodate articles of various thickness. In the preferred embodiment, carrier  11  is sized to carry sheets of music. 
         [0035]      FIG. 3  shows the back side of the carrier  19  with strap  20  secured under loop  16 . This configuration enhances stability especially when carrier  11  is attached to a large and/or oddly shaped case. 
         [0036]      FIG. 4  shows the inside of the carrier  11 . Specifically,  FIG.4  shows the interior with pockets  13  and  15 . There can be a plurality of pockets of different sizes and shapes inside carrier  11 . The pockets accommodate pencils, business cards, calculators, cell phones and other object which need to be carried. The pockets can also be attached to the inside face of the front side  10 . Alternately, the pockets could be attached to the outside of front side  10 , under or on flap  12 . 
         [0037]      FIG. 5  shows a partial perspective view of strap  19  attached to the handle  32  with the remainder of carrier  11  cut away. Strap  16  conforms to the contours of case  30 .  FIG. 5  illustrates that the carrier  11  is adjacent only to one side of case  30  and does not interfere with the use of the handle  32 . This allows the user to freely open the case  30  without interference from carrier  11 . Moreover,  FIG. 5  illustrates the interaction of handle  32  and strap  20 . Handle  32  is inserted through strap  20 . Specifically, slit  24  permits entry of the top of the handle  32  through strap  20  and handle cut outs  26  allow carrier  11  to be securely attached to case  30 . Strap  20 , slit  24  and handle cut out  26  can be reinforced as needed with a suitably strong material along the periphery thereof. Excess may be trimmed or the excess may be folded under for future use with larger cases. 
         [0038]    In one embodiment, front wall  10  and back wall  19  are made of generally orthogonal pieces of material that are joined at their periphery. The joint can be by staples, glue, heat sealing or any other method known to those skilled in the art. In the preferred embodiment, carrier  11  is constructed partially or completely of transparent polyurethane material because of water resistance, transparency, ease of manufacture and relative low cost. The material is chosen to provide adequate protection to articles stored inside. However, carrier  11  could be made from nylon, leather or any other suitable material known to those skill in the art. 
         [0039]    As illustrated in  FIGS. 6-8 , a combination of transparent and non-transparent materials could be used such as a transparent polypropylene material that is formed into a window with a woven nylon material forming the remainder of the body. A nylon peripheral border can also be included around the edges of the invention for structural and aesthetic purposes. This would serve the aesthetic function as well as to protect the edges of the invention from fraying or other damage. A logo can also be included as desired through molding, glue, stitching or other methods. 
         [0040]    In the embodiment shown in  FIGS. 6-8 , carrier  100  comprises a translucent front panel  106 , an closure flap  102 , rear panel  108 , perferrably formed from a nylon or equivalent fabric, fastening straps  110  and hook and loop closure fasteners  104 . The periphery  116  is formed from a nylon or equivalent fabric welt  116 . The bag can be of any shape and size appropriate. 
         [0041]    A method is also disclosed in carrying sheet music in a translucent folder. The folder, shown in  FIGS. 1-5 , would have generally orthogonal walls and in one embodiment, would have expandible sides to accommodate articles of varying thickness. The sides of the folder can be joined by glue, staples, heat sealing or any other method known to those skilled in the art. The back side  19  would extend over the folder&#39;s front side  11  to form a closure  12  in the form of a flap which keeps the sheet music and related articles securely inside the folder with a fastener. The folder is attached to a strap  20  having a plurality of slots. The strap  20  is attached to the back side of the folder. 
         [0042]    The user places the back side  19  of the folder  10  adjacent case  30 . The user then decides which of the plurality of slots  24  in strap  20  is appropriate to accommodate the shape and size of the case. Once the appropriate slot is selected, the user then inserts the case handle through the slot so the strap lies over the handle. The user then inserts sheet music or other documents and things inside the carrier and securely fastens the flap to ensure the articles are protected and secure. 
         [0043]    An alternate embodiment would enable a user to provide added stability to the carrier while attached to the case. This may be needed if the case is oddly shaped and/or sized. Before the user attaches the carrier to the case, the user inserts the strap  20  though loop  16  on the back of the folder. The user then places the carrier adjacent the case to determine which slot  24  in strap  20  is appropriate to place over the handle. Once the user places the handle through the appropriate slot, the loop then serves to provide added stability to the carrier while attached to the case. 
         [0044]      FIGS. 6-8  illustrate another embodiment of the invention. Illustrated here are folder  100 , flap  102 , front panel  106 , back panel  108 , a hook and loop closure  104 , logo  114 , hook and loop straps  110 , loops  112  and nylon border  116 . Folder  100  is attached to a case handle by using straps  110 . Straps  110  are attached at or near the bottom of back panel  108 . At least one strap is used to enhance stability and security to the case handle. Depending on the size and shape of the case, loops  112  can be used with straps  110 . Loops  112  are attached at or near the top of back panel  108 . At least one loop  112  can be provided in different positions on the back panel  108  to accommodate cases of different shape and size. Each of the straps  110  are inserted through a loop  112 . This serves to abut the back panel  108  to a side of the case before the straps are attached to the case handle. Straps  100  are constructed from hook and loop material so that the straps may be engaged to securely fasten thereof. Once the straps engage the handle, the excess hook and loop strap is trimmed and the strap is pressed together so that the hook and loop fasteners become engaged. 
         [0045]    It should be understood that in the process of attaching and manufacturing the loop to the folder, the loop should be wide enough to allow the strap under it, but still keep the body of the folder close to the case it is attached to in order to provide enhanced stability to large and/or oddly shaped cases. 
         [0046]    Also included is a method of using the above embodiment. This method is directed toward carrying sheet music in a folder having a translucent front panel. The folder has generally orthogonal walls and in one embodiment, has expansible sides to accommodate articles of varying thickness. The sides of the folder can be joined by glue, staples, heat sealing or another other method known to those skilled in the art. The folder&#39;s backside extends upwardly into a flap which extends over the front of the folder. This flap keeps the sheet music and related articles securely inside the folder with at least one fastener. The folder has at least one hook and loop strap extending upwardly from the back surface of the folder. A plurality of strap engaging loops is fastened to the back surface near the top thereof. 
         [0047]    The user places the backside of the folder adjacent to the case. The user then decides which of the loops to insert the strap though. This would be determined by the size and shape of the case. Once the loops, if any, are selected, the user inserts the straps through the loops. The straps are then wrapped around the handle and back inter contact with a lower portion of the strap. The excess hook and loop strap is then trimmed and the folder is securely attached to the case. The user can then insert sheet music documents, manuscripts or music related articles inside the carrier and securely fasten the flap to ensure the articles are secure. 
         [0048]    While there have been described what are considered to be preferred embodiments of the present invention and the methods of use, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herein.
