CROSS-REFERENCE TO OTHER APPLICATIONS 
       [0001]    This application claims the benefit of US provisional patent application No. 62/175,887, filed 15 Jun. 2015, entitled Clip for Attaching Auxiliary Weight Bearing Items to Shoulder Strap and US provisional patent application No. 62/242,879, filed 16 Oct. 2015, entitled Clip for Attaching Auxiliary Weight Bearing Items to Shoulder Strap. 
     
    
     INCORPORATION BY REFERENCE 
       [0002]    All publications and patent applications mentioned in this specification are herein incorporated by reference in their entirety to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference. 
       FIELD 
       [0003]    The embodiments described herein relate generally to transportation of items, and more particularly, to a clip for attaching auxiliary weight bearing items to a strap. 
       BACKGROUND 
       [0004]    The subject matter discussed in this section should not be assumed to be prior art merely as a result of its mention in this section. Similarly, a problem mentioned in this section or associated with the subject matter provided as background should not be assumed to have been previously recognized in the prior art. The subject matter in this section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology. 
         [0005]    People wear items with shoulder straps for many reasons, such as carrying things (e.g., book bag, backpack, child carrier, purse, and the like) or back support or floatation (Personal Flotation Device) or emergency supplies or tactical supplies. Wearing heavy items with shoulder straps to one part or side of the body introduces several problems, such as uneven weight distribution which can lead to pain, too heavy a weight on one side of the body which can lead to balance issues, security risk if valuables are out of direct eyesight and difficulty accessing things within the carrier, for example, a map contained within a backpack is difficult to access unless the user removes the backpack. 
         [0006]    Conventional devices exist to introduce auxiliary items to strap systems. However, most conventional devices and systems support only limited light-weight applications and/or tend to slip with higher weight. Some of the conventional devices allow a user to attach items, but the added weight adds unexpected vertical and horizontal tensions to the existing strap, causing further complications, such as extensive strap wear or imbalance. Some of the conventional devices allow a user to attach items, but only in fixed locations along the strapping system. Yet further conventional devices may work for attaching auxiliary items, but are specific to one type of strapping system and are not interchangeable among different strapping systems. 
         [0007]    Therefore, what is needed is a device for easily attaching auxiliary items to any strapping system, wherein the device provides for improved weight distribution, heavier weight applications, flexible positioning along the strapping system, and improved balance compared to conventional devices. 
       SUMMARY OF THE DISCLOSURE 
       [0008]    A simplified summary is provided herein to help enable a basic or general understanding of various aspects of exemplary, non-limiting implementations that follow in the more detailed description and the accompanying drawings. This summary is not intended, however, as an extensive or exhaustive overview. Instead, the sole purpose of this summary is to present some concepts related to some exemplary non-limiting implementations in a simplified form as a prelude to the more detailed description of the various implementations that follow. 
         [0009]    A first example of a clip is used to attach an item to a strap worn by a person. The clip includes a body and a closure mechanism. The body has a bottom portion having a bottom hinge end and a bottom closure end, a top portion having a top hinge end and a top closure end, and a hinge portion at the bottom and top hinge ends hingedly connecting the top and bottom portions for movement of the top and bottom portions about a hinge axis. The clip is placeable in a closed position with the top and bottom portions directly opposite one another, and in an open position with the top portion extending away from the bottom portion. The bottom portion has a bottom surface and the top portion has a top surface positioned opposite the bottom surface when the clip is in the closed position. At least one of the top and bottom surfaces comprising strap-engaging, non-slip structure. The top and bottom surfaces define an interior space when the clip is in the closed position. The interior space is configured to accommodate a user-wearable strap positionable between the bottom and top surfaces when the clip is in the closed position with the strap-engaging, non-slip structure engageable with the strap so that the clip is securable to the strap by the engagement of the strap-engaging, non-slip structure with the strap. The closure mechanism includes a first closure portion carried by the bottom portion and a second closure portion carried by the top portion. The closure mechanism is configured to secure the top portion to the bottom portion when the clip is in the closed position. The closure mechanism includes a stabilizer preventing movement generally parallel to the hinge axis of the first lock portion relative to the second lock portion when the clip is in the closed position.

     DETAILED DESCRIPTION 
       [0053]    In the following detailed description of the invention, numerous details, examples, and embodiments of the invention are described. However, it will be clear and apparent to one skilled in the art that the invention is not limited to the embodiments set forth and that the invention can be adapted for any of several applications. 
         [0054]    The device of the present disclosure may be used to attach auxiliary items to a strap system, such as a shoulder strap, and may be comprised of the following elements. This list of possible constituent elements is intended to be exemplary only, and it is not intended that this list be used to limit the device of the present application to just these elements. Persons having ordinary skill in the art relevant to the present disclosure may understand there to be equivalent elements that may be substituted within the present disclosure without changing the essential function or operation of the device.
       Bottom Portion   Top Portion   Hinge or Flexible Connection   Closure Mechanism including Stabilizer   Teeth to Create Friction       
 
         [0060]    The various elements of the device of the present invention may be related in the following exemplary fashions. It is not intended to limit the scope or nature of the relationships between the various elements and the following examples presented are illustrative examples only. Like elements in various examples can be referred to with like reference numerals. 
         [0061]    By way of example, and referring to  FIGS. 1A-1B , an embodiment of the invention include a clip  10  for attaching auxiliary weight bearing items, such as those discussed below, to a strap  12 , see  FIGS. 5A and 5B , such as a shoulder strap. In some examples the auxiliary weight bearing item could be supported elsewhere on the person&#39;s body, such as by a tool belt worn by the person, but be attached to a lanyard or other item with the lanyard or other item attached to the clip  10 ; in these examples the auxiliary weight bearing item would be indirectly attached to the clip  10 . The clip comprises a bottom portion  14  hinge-ably attached to a top portion  16  by a hinge attachment  22  for pivotal movement about a hinge axis  23 . The clip is configured to be in an open position as in  FIG. 1B  or a closed position as in  FIG. 1A . When the clip  10  is in a closed configuration, a stabilizer extension in the form of a securement tooth  18  at the top closure end  20  of the top portion  16  distal from the hinge attachment  22  is configured to engage with a lock groove  24 , also referred to as stabilizer groove  24 , formed in a locking arm  26  on an end of the bottom portion  14  distal from the hinge attachment  22 , defining an interior space  28 , see  FIG. 1A , configured to accommodate a strap  12 . The combination of securement tooth  18  and lock groove  24  constitute a stabilizer  25 . Stabilizer  25  helps to prevent the top portion  16  of the clip  10  from slipping vertically when weight is applied to clip. Stabilizer  25  therefore prevents movement generally parallel to the hinge axis  23 ; what is meant by preventing movement is that small amounts of movement, consistent with the limitations of manufacturing processes and within manufacturing variations, are permitted. The distal end  20  of the top portion  16  may also engage with a locking tooth  30  of a lock arm  26  on the distal end of the bottom portion  14  to help secure the clip  10  in a closed configuration. Distal end  20  and locking tooth  30  act as parts of a closure mechanism for clip  10 . A top surface  32  of the top portion  16  and a bottom surface  34  of the bottom portion  14  may together form interior walls in the interior space  28 . The interior walls  32 ,  34  may comprise a plurality of strap-engaging teeth  36 , wherein the teeth are configured to penetrate into a strap  12 , preventing the clip from sliding, commonly sliding vertically, along the length of the strap. The clip  10  may further comprise an optional spring and/or stop mechanism used to provide an open and/or close bias for the hinge mechanism. The item can be attached to the clip  10  before or after the clip is secured to the strap  12 . 
         [0062]      FIG. 2  shows another example of clip  10  in a closed position with hook-type fasteners  40  extending from an outer surface  42  of the top portion  16 . 
         [0063]    By way of another example, and referring to  FIGS. 3A-3C and 4 , some embodiments of the invention include a clip  10  for attaching an auxiliary weight bearing item to a strap  12 , such as a shoulder strap, the clip comprising a single folded material that consists of top portion  16 , bottom portion  14  and one or more flexible connections in the form of a living hinge  22  for pivotal movement about a hinge axis  23  in the form of a living hinge axis. Living hinge  22  is made so that the top portion and bottom portion are biased towards a partially open position, see  FIGS. 3A-3C , but possible to flex to a more open position as to allow a strap  12  to be placed between the top portion and bottom portion or flexed to one of several closed positions, where an interior space  28 , see  FIG. 5B , is created by the closure of the top portion and the bottom portion, the interior space configured to accommodate a strap. When the clip  10  is in a closed configuration, a securement tooth/stabilizer extension  18  on an end of the bottom portion distal from the living hinge  22  is configured to engage with a lock/stabilizer groove  24  on an end of the top portion  16  distal from the living hinge, defining an interior space  28  configured to accommodate a strap  12  as shown in  FIG. 5B . Stabilizer extension  18  and stabilizer groove  24  constitute a stabilizer  25 . As with the example of  FIGS. 1A and 1B , the engagement of the stabilizer/securement tooth  18  and stabilizer/lock groove  24  can help prevent the top portion of the clip from slipping vertically when weight is applied to clip. The distal/top closure end  20  of the top portion  16  engages one of a row of locking teeth  30  on locking arm  26  at the distal end of the bottom portion  14  to help secure the clip  10  in one of several closed configurations. A surface  32  of the top portion  16  and a surface  34  of the bottom portion  14  may together form the interior walls in the inner space  28 . The interior walls may comprise a plurality of strap-engaging teeth  36 , wherein the teeth are configured to penetrate into a strap  12 , preventing the clip from sliding vertically along the length of the strap. 
         [0064]    The interior walls of the top and bottom portions may comprise a plurality of strap-engaging teeth  36  that are in two rows on the top portion  16  (e.g. six teeth and seven teeth) and two rows on the bottom portion  14  (e.g. six teeth and seven teeth) that are offset from teeth rows on the top portion. When a strap(s)  12  is enclosed within the interior space  28  formed when the clip top portion and bottom portion are in the closed configuration, the plurality of teeth come in contact with the inserted strap(s) and cause significant friction between the inserted strap(s), clip top portion and clip bottom portion wherein the friction prevents the clip from sliding vertically along the length of the strap. This is one embodiment presented for example purposes only. This invention covers all other configurations, as well, depending upon the application. 
         [0065]    The plurality of teeth on the clip top portion interior wall may optionally be grouped into several teeth that are raised (e.g. nine teeth as represented in  FIG. 5 ) and others that are even with the clip top portion interior wall (e.g. four teeth as represented in  FIG. 5 ). 
         [0066]    Referring to  FIG. 7 , the plurality of teeth  36  that cause friction between the inserted strap, clip top portion  16  and clip bottom portion  14 , may optionally be part of a strap-engaging teeth components  46 ,  47 . Teeth components  46 ,  47  are pluggable into the interior walls  32 ,  34  and interchangeable with one another to provide different combinations of friction-creating options depending upon the specific application. 
         [0067]    Referring to  FIGS. 7A-7D , strap-engaging teeth components  46 ,  47  comprise a plurality of sharp teeth  48 , or less sharp teeth or rounded teeth  49 , or offset rectangular raised walls  50 , or any other component that causes significant friction between the inserted strap(s), clip top portion and clip bottom portion wherein the friction prevents the clip from sliding vertically along the length of the strap when the clip is in the closed position. 
         [0068]    The outer surface of the clip top portion may comprise a fastener configured to attach an auxiliary item thereto. For example, as shown in  FIGS. 1A, 1B and 3A-3C , the fastener may be comprised of a slatted protrusion  52 , also referred to as a slatted webbing-attachment type fastener or simply slatted fastener, wherein the slats, created by slots  54  formed in slatted protrusion  52 , are used to secure webbing  56  from an auxiliary item  58 , see  FIGS. 8A-8C , resulting in the auxiliary item hanging from the strap. In other embodiments, the fastener may comprise hooks  40 , such as those shown in  FIG. 2 , or any other conventional fastener, such as hook and loop fastener, snap(s), button(s), screw(s), tie(s), clip(s), carabineer(s) or the like. 
         [0069]    Referring to  FIG. 3B , there may optionally be a raised edge  60  on the inner portion of the top of clip distal to the flexible connection that is located between the clip top portion lock/stabilizer groove  24  and the plurality of strap-engaging teeth  36 . This raised edge  60  provides a demarcation so that straps, webbing or the like that are placed within the interior space do not interfere with the lock/stabilizer groove function. 
         [0070]    As shown in  FIGS. 5A and 5B , the clip can may be fastened around a strap  12  by placing the strap into the clip when it is in the open configuration and compressing the clip about the strap into the closed and locked position, such that the clip top portion is positioned adjacent to a surface of the strap facing away from the user, wherein an auxiliary item  58  is attached to the fastener  52 . As a result of the structure of the clip, the added weight from the auxiliary item  58  may be more evenly distributed than with conventional devices. Specifically, the weight may be centered to the strap to optimize strap support. Moreover, the clip of the present disclosure may be used generically with any existing strap or shoulder strap system and positioned anywhere along it providing balance, weight distribution, security and accessibility benefits. Invention may be particularly useful for providing ready access to auxiliary items by persons with mobility problems; in such situations the straps passing over the chest of the user of a strapping or harness system without a backpack component could be used to provide ready access to items while the user is seated. In embodiments, the clip may be configured to support at least 25 pounds or more without slipping along the strap. It also allows the user to carry more items by making the shoulder strap accessible to additional packs. 
         [0071]      FIGS. 6A-6C and 9A-18B  present exemplary clip invention uses with different fasteners, straps and/or packs. Some of the unique benefits of this invention applied to all exemplaries include making items more accessible by placing them on the front of the body rather than back, making them more securely fastened to the strap so they remain in that fixed position, making items more secure because they are always in sight rather than on your back, freeing the user&#39;s hands for other activities since they can place items in an accessible pack rather than hold the item and shifting weight to the front thereby improving weight distribution and potentially posture. This list of exemplary uses is intended to be exemplary only, and it is not intended that this list be used to limit the uses of the present application to just those listed. Persons having ordinary skill in the art relevant to the present disclosure may understand there to be additional uses to which this invention applies. 
         [0072]    As discussed above,  FIGS. 6A-6C  show how the clip invention may be used to add a generic weight bearing auxiliary item  58  in the form of an auxiliary pack  58  to a shoulder strap  12  using the clip fastener element  10  and webbing  56  extending from the auxiliary pack. The auxiliary pack may have many uses, for example, to hold supplies for fishing, hunting, hiking, camping, climbing, boating, work, school, baby, photography, business travel, public safety, emergency and tactical to name a few uses. 
         [0073]      FIGS. 8A-8C  show how the clip invention  10  may be used to add a generic weight bearing auxiliary pack  58  to a shoulder strap  12  using the clip top portion  16 , auxiliary pack and generic securement mechanism of the auxiliary pack to clip top portion. In  FIG. 8C  strap  12  is not shown for clarity of illustration. Referring to  FIG. 5B , when the clip is in the closed locked position, the raised group of teeth  36  on the clip top portion will come in the most contact with the strap while the teeth even with the clip top portion interior wall will come in the most contact with the securement mechanism, thereby providing a secure fit when the clip is in the closed position. The auxiliary pack may have many uses, for example, to hold smartphone (refer to  FIGS. 10-10B ), water bottle (refer to  FIGS. 11-11A ), wallet, permits, and supplies for fishing, hunting hiking, camping, climbing, boating, work, school, baby, photography, business travel, public safety, emergency and tactical to name a few uses. 
         [0074]      FIGS. 12-12B  show how the clip invention  10  may be used to add two generic weight bearing auxiliary packs to a shoulder strap  12  (not shown in  FIGS. 12A and 12B ) using the clip fastener  52 , clip top portion  16 , webbing  56 , auxiliary packs  58  and generic securement mechanism of the auxiliary pack to clip to top portion  16 . The two auxiliary packs may have many uses, for example, to hold smartphone, water bottle, wallet, permits, and supplies for fishing, hunting, hiking, camping, climbing, boating, work, school, baby, photography, business travel, emergency, public safety and tactical to name a few uses. 
         [0075]      FIGS. 13, 13A  show how two clips  10  may be used together to add a generic weight bearing auxiliary pack  58  to two shoulder straps  12  using two clip fasteners  10  and webbing  56 . The two clips are positioned on two parallel shoulder straps at approximately the same position on each of the two shoulder straps. The auxiliary pack is connected to each of the clip fasteners. Benefit of this configuration is ability to support heavier auxiliary weight distributed across two clip inventions, centering the auxiliary pack to the front of the body and shifting more weight from back to front providing better balance and comfort (refer to  FIG. 24 ). The auxiliary pack may have many uses, for example, holding supplies for fishing, hunting, hiking, camping, climbing, boating, work, school, baby, photography, business travel, emergency, public safety and tactical to name a few uses. 
         [0076]      FIG. 14  shows another configuration where two clips  10  may be used together to add a generic weight bearing auxiliary pack to a shoulder strap using two clip fasteners, webbing and auxiliary pack. The two clips are positioned on two parallel shoulder straps, one clip at a higher position on one shoulder strap and the second clip at a lower position on the other parallel shoulder strap. The auxiliary pack is connected to each of the clip fasteners and positioned on the body at a diagonal angle. Additional benefit of this configuration is ability to center the auxiliary pack to the front of the body at a more comfortable diagonal angle, depending upon preference. The auxiliary pack may have many uses, for example, holding supplies for fishing, hunting, hiking, camping, climbing, boating, work, school, baby, photography, business travel, emergency, survival, tactical, and military to name a few use types or use categories. Various alternative auxiliary pack embodiments are included based upon the typical, customary, or even specialized equipment or components of a specific use type or category. 
         [0077]      FIGS. 15, 15A  show how the clip  10  may be used to add an existing auxiliary pack  58  typically worn on a belt using a fixed belt loop  64  to a shoulder strap  12  using the clip top portion  16  and auxiliary pack with fixed belt loop. The auxiliary pack typically worn on a belt may have several benefits if worn on the shoulder strap including comfort, better accessibility, carrying more packs (both on the belt and shoulder strap). Note that in this configuration, the clip fastener may become inaccessible if the fixed belt loop covers the clip fastener.  FIG. 15B  illustrates an example similar to  FIG. 15A  but in which the belt loop is not a fixed belt loop but has hook and loop type fastener elements  66  at one end. 
         [0078]      FIGS. 16-18  B show several other examples of ways in which an auxiliary item may be connected and secured to the clip top portion including screws  68 , metal clip and lock arms. These are not meant to present a complete list of connection methods but rather to show alternative uses and the flexibility of the clip design. Once connected to the clip top portion, the auxiliary items and clip may be secured to a strap—refer to  FIGS. 5A and 5B . Specific uses may include connecting a video camera or light to a shoulder strap. 
         [0079]    The clip  10  is designed for use with many types of straps  12 . The following list provides some examples of straps for which one or more of the various embodiments of the clip invention applies. It is presented for example only and not meant to be limited to nor all-inclusive of all types of straps for which the clip invention applies: Hiking backpack shoulder straps, fishing backpack or waders shoulder straps, hunting backpack shoulder straps, biking backpack shoulder straps, climbing backpack shoulder straps, messenger bag shoulder strap, sling bag shoulder strap, book bag shoulder straps, baby carrier shoulder straps, purse shoulder straps, personal flotation device shoulder straps, public safety emergency supplies backpack shoulder straps (incl. fireman, police, emergency medical services, etc.), medical supplies shoulder straps, military tactical backpack shoulder straps, sports bag shoulder straps, back support system shoulder straps, luggage backpack shoulder straps, utility worker supplies backpack shoulder straps, traveler/commuter backpack shoulder straps, name a few. 
         [0080]    If desired, the components may be reconfigured such that the clip is designed for use with other types of strap-like elements, such as belts, suspenders, ropes, chains, harnesses, metals rods, wood poles, etc., either vertically or horizontally enabling addition of weighted auxiliary items to the elements. Reconfiguration may include making some elements swivel (e.g. fastener), changing the shape of the clip invention without changing the function, making elements expandable and contractible (e.g. changing the length of the clip top and bottom portions to change the size of the space created for straps when the clip is in the closed position). Moreover, the clip may be integrated into other products to create new carrier products, such as new types of front packs, tackle boxes, purses, key/phone holders, tool boxes, tool carriers, baby carriers, water carriers, school supply carriers, book carriers, equipment carriers, hospital patient medical device/monitors carrier and the like.
