Title: Diaper Changing Accessory Organizer

Description:
This is a continuation-in-part of, U.S. Ser. No. 11/134,962, filed on May 23, 2005, now U.S. Pat. No. 7,171,707, entitled Portable Rollup Pack, and which is hereby incorporated by reference in its entirety. 
    
    
     BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to an apparatus for transporting personal articles and more specifically to portable packs for organizing, storing, and transporting substantially flattened or compressible articles alone or along with rolled up, folded, or flattened cushioning articles such as sleeping gear, exercise and seating mats, personal towels, diaper changing mats or pads, beach towels, blankets, and other similar articles.  
      2. Background Art  
      Adults as well as children often engage in overnight camping trips as well as slumber parties. For such extended stays, the overnighter generally must pack both a sleeping bag and a personal carrying pack. Typically, any personal items are stored in a carrying pack such as a school backpack or knapsack that is transported on the individual&#39;s back or hand-carried. The sleeping bag is also generally rolled up into a bulky cylindrical package and lugged under one arm or otherwise carried by a handle. Thus, even with the carrying pack worn on the back, this transportation method occupies at least one arm and takes up a significant amount of space. While the size of some backpacks allows the user to compress the sleeping bag into the bottom of the pack, this is not practical for many of the larger, less compressible sleeping bags commonly used on overnight trips. In addition, the sleeping bag is typically stored at the bottom of the pack and is not readily accessible without removing the entire contents of the pack.  
      In U.S. Pat. No. 6,543,072 to Hsu an integrated knapsack and sleeping bag combination is described in an attempt to reduce some of this transportation concern. However, the sleeping bag in this combination is connected to the lining of the knapsack and thus does not facilitate cleaning the sleeping bag or replacing the sleeping bag once it is outgrown or degrades so as to be no longer useful.  
      Another solution for carrying personal items is described in U.S. Pat. No. 5,622,300 to Robinson. This patent describes a roll pack for transporting articles to the beach or a picnic area. The roll pack described in this patent describes a set of pockets along one edge for storing articles including a pillow and a set of pockets along the opposite edge for storing a set of tie wraps so as to prevent the hook and loop fasteners from becoming fouled with dirt or other contaminants. The majority of the roll pack is taken up by a large intermediate section made up of an absorbent material such as terry cloth. This central enlarged section is provided for use as a towel so that the user does not need to bring a separate towel. By providing such a large towel section, this roll pack configuration wastes a considerable amount of useable storage space. Moreover, it would be impractical to store articles up against the wet towel section as such articles could absorb the towel moisture and become damaged.  
      In addition to focusing on various overnight travel needs, other travel accessories are geared more specifically to address diaper changing needs for day traveling and/or extended overnight stays. For example, U.S. Pat. No. 5,299,336 to Marteeny discloses a portable diaper changing station for changing a baby on a protruding support surface such as a bathroom sink. The changing station includes a non-bendable rigid central section with a handle and supporting a cushioning pad. A nonporous wipeable carrying case is releasably attached to the upper surface of the central section in the form of a pair of opposing flaps that may cover the cushioning pad. Thus, each flap may be removed from the central section. One of the flaps includes a series of pockets with openings running parallel to a long edge of the cushioning pad for storing spare diapers. The other flap does not include any pockets and instead provides a cushioning surface to protect the baby from protruding objects such as a sink faucet. The flaps are closed together over the cushioning pad with opposing sets of complementary hook and loop fasteners. In use, the rigid central section is placed over a sink opening. The rigidity of the central section prevents the changing station from sagging into the sink under the weight of the baby. The flaps are released from one another with the cushioning flap being propped up against the sink faucet and the other flap being lowered to hang over the outer edge of the sink. The baby is placed on the cushioning pad of the central section with the baby positioned perpendicularly to the diaper changing person and changed conventionally. While this changing station is useful for changing a baby on a surface such as a sink because of its rigid section, such rigidity throughout the central section is also limiting. For instance, the rigid section must be large enough to accommodate most sink openings. This renders this changing station rather bulky or requires the user to carry multiple changing stations of different sizes. The narrow cushioning pad includes an outwardly bowed surface and is also raised significantly off the surrounding surface and, if the provided restraining straps are not used, the baby may easily roll off the narrow pad toward the sink edge and be injured. Also, there is a significant amount of wasted storage space as both the central section and cushioning flap have no storage capacity. As there are no closed pockets, personal items may easily be lost as the changing station is carried and jostled throughout the day. Thus, the user would still be required to carry and secure personal items in a separate bag such as a purse, wallet, or other handbag.  
      Another product called the Changing Station has been described as a lightweight changing station that comes with straps so that it may be attached to another backpack, diaper bag, or stroller, or as a carry alone. Like the Marteeny changing station disclosed above, the Changing Station has a central diaper mat section disposed between a storage section and a cover flap. The storage section includes two spaced apart pockets to either side of a daisy chain strap. The pocket openings are next to the diaper changing pad and are oriented parallel to the long edges of the diaper mat. Due to this parallel arrangement, when the baby is on the integrated changing pad, the baby&#39;s body inhibits the user from easily withdrawing articles from the pockets. Also, the left side openings are not ergonomically proper for right handed people, the majority of the population. In addition, since the two pockets are presumably loaded with baby changing supplies such as a diaper and wipes, the Changing Station lacks considerably as a standalone product. A purse or another pack would be a necessity. Furthermore, the diaper changing pad is integrated into the body of the Changing Station and thus is not replaceable due to wear and tear or easily removed for cleaning. This configuration also omits the entire section beneath the pad as a potential storage space. The flap section provides no storage capability and provides another wasted storage space. Similarly, the external surface of the Changing Station when closed up fails to utilize the exterior space for any storage capacity.  
      A similar construction can be found in U.S. Pat. No. 4,886,150 to Fitzsimmons. However, the Fitzsimmons baby accessory carrier includes a detachable diaper changing pad overlying a central section with both outer sections containing pockets having openings facing the center section. The carrier is constructed of a soft quilted material. To assume a purse-like configuration, this carrier also requires a folding order that requires three steps as first one side is folded over the central section about a first transverse axis and then the second side is folded about a second spaced apart transverse axis over onto the first side. Then the entire elongated package is folded in half about a longitudinal axis to bring a pair of opposing handles together. The package is then tied together using tie strips to provide the purse-like configuration.  
      While the changing pad of the Fitzsimmons carrier can be removed, there is no storage space beneath the pad. In addition, as with the Changing Station, the pocket openings face the center section and thus removal of the articles therein is inhibited when the infant is on the pad. Also, the pockets must be subdivided in half to accommodate the folding process and thus limit the article size that can be placed therein. Moreover, the reduced size of the pad to fit within the confines of the central section limits the usefulness of the pad as a changing surface as the pad size may be too restrictive in some instances by limiting the infant&#39;s placement. Finally, the soft quilted body of the carrier will likely sag under a significant weight load and not retain its purse-like shape very well when folded into that configuration.  
      Other exemplary diaper bags can be found in U.S. Pat. No. 5,743,649 to Gonzalez and U.S. Pat. No. 4,566,130 to Coates. The Gonzalez diaper bag is in the form of a horizontally elongated, substantially rectangular bag body having opposing handles at either end. Pockets located in the outer regions of the bag are closed off using a flap. The entire bag is then folded in half to bring the handles together to form a rather unwieldy, elongated, purse-like configuration. There is no attachment for a diaper changing pad and thus such pad, if used, must be crammed into one of the pockets. In use, the changing pad would have to be retrieved from a pocket first and then laid out on a flat surface in order to perform the changing. Since many diaper changing activities involve at least a modicum of speed, this arrangement detracts from that purpose. In addition, the soft corduroy or flannel material will typically sag under a significant weight load and not retain its purse-like shape when being carried. According to the patent, the interior pockets are opaque thus concealing the contents. This adds to the search time for articles therein and is unnecessary since the pockets are concealed when the bag is folded up.  
      The Coates patent discloses a carrying bag for diaper accessories in the form of a vertically elongated, substantially rectangular bag body with a handle at the top. The bag body has three vertically aligned sections, each with a pocket having an opening at the top of the respective section. The center section may include a removable waterproof pouch for containing soiled diapers. A fastener such as a zipper runs down the sides of the bag body. To convert to a carrier, the two end sections are folded inwardly, one over the other, onto the middle section. This folding process requires that specific order to form the final configuration. The sections are then sealed together with end snap fasteners and zipped up along the sides and can be carried by hand or as a backpack. Alternatively, the bag folds in half like the Gonzalez carrier above to pair up opposing handles. According to the patent, when the bag body is laid out, the infant may be changed directly on top of the pockets. However, there is no intervening pad which means the entire bag would have to be cleaned or a pad would have to be retrieved from another pocket adding to the changing time. Also, due to its compact size and narrow profile, the changing surface area is unlikely to be sufficient.  
      Thus, there exists a need for an easy to use, portable travel pack that maximizes storage space reducing the need for extra baggage and provides superior organizational features while being capable of transporting a diaper changing pad and related accessories along with personal items, providing a changing station, and freeing the user&#39;s hands during transportation.  
     BRIEF SUMMARY OF THE INVENTION  
      In accordance with a preferred embodiment of the present invention, a portable diaper changing accessory organizer is provided in the form of an elongated bag body having pivotal connections between first and second storage sections and a common central section with the bag body having an interior surface with at least one storage pocket in each of the sections and a third pivotal connection substantially parallel with the first two connections along with a capturing element and a carrying strap whereby a user may fold the first and second storage sections onto the central section about their respective pivotal connections to form first and second overlapping regions and then fold and releasably capture these regions together with the capturing element to transport the bag body in a folded configuration with the carrying strap.  
      In another aspect of the present invention, a diaper changing mat or pad may be releasably fastened to the interior surface of the diaper bag body and folded up along with the storage sections prior to transport.  
      Yet another aspect of the present invention involves the incorporation of rigidity and/or retention features such as a rigid spine to prevent sagging during transportation or suspension of the folded bag body from a stroller handle and outer section retaining elements for releasably securing portions of the overlapping regions to a central anchor to further prevent sagging and/or inadvertent unfolding.  
      The present invention may also include a series of pockets substantially spanning the length and height of the bag body that may provide waterproof compartments along with viewing windows to assist in the quick retrieval of the packed accessories.  
      A method of preparing a diaper changing accessory organizer for transport is also disclosed herein both with and without a removable diaper changing mat.  
      Other aspects of the present invention will become apparent with further reference to the following drawings and specification.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Referring now to  FIGS. 1-2  illustrating interior and exterior views of an exemplary portable rollup pack in accordance with the present invention and generally designated  10 , the rollup pack is provided for organizing, storing, and transporting personal articles, items, or objects including a rolled up sleeping bag for extended stays. An exemplary sleeping bag, generally designated  12 , is illustrated in  FIG. 3 . When laid flat as in  FIGS. 1-2 , the rollup pack  10  generally includes a substantially rectangular bag body  14  that may be divided generally into a medial carrying section  16  interposed between a left lateral wing wrap  18  and a right lateral wing wrap  20 . The bag body is constructed of an outer layer of fabric  22  sewn to a similarly dimensioned inner layer of fabric  24  forming an exterior bag body surface  26  and interior bag body surface  28 , respectively. The top edge  21 , bottom edge  23 , left hand edge  25 , and right hand edge  27  of the bag body are then finished off with conventional ¼ inch filled piping  30  circumscribing the perimeter of the bag body. In this exemplary embodiment, the overall height of the bag body measured from the top edge  21  to the bottom edge  23  is approximately 12.5 inches and the overall length is approximately 45 inches measured from the left hand edge  25  to the right hand edge  27  as viewed in  FIG. 1 .  
      With continued reference to  FIG. 1 , the interior surface  28  of the bag body  14  may be divided into a number of pockets for organizing, storing, and transporting personal articles. In this exemplary embodiment, the bag body includes six pockets arranged across substantially the entire length and height of the bag body as viewed in  FIG. 1 . The leftmost upper pocket  31  and lower pocket  32  are vertically stacked and span the entire height of the bag body. In this exemplary embodiment, these dual pockets subdivide the height of the bag body equally. These dual pockets include a common bottom edge  34  that corresponds with the leftmost edge  25  of the bag body as viewed in  FIG. 1 . The dual pockets also share a common sidewall  35 . Each pocket  31 ,  32  includes a vertically projecting top edge  36 ,  38 , respectively, forming an opening into the respective pocket. The openings face the right hand end  27  of the bag away from the left hand edge  25 . The top edges of the pockets  31 ,  32  may be lined with a conventional hook and loop type closure as indicated by strips  37 ,  39 , respectively, to seal off the contents of the pocket. A convenient pull tab  40 ,  42  is provided on each pocket  31 ,  32 , respectively, to facilitate separating the hook section from the loop section to gain access to the pocket.  
      These dual pockets  31  and  32  are typically dimensioned to accommodate smaller personal articles. In this exemplary embodiment, these pockets measure approximately 7.5 inches in depth from the bottom edge  34  of each pocket to the top opening edge  36  or  38 , respectively. Depth is generally defined as the distance from the bottom edge of a pocket to a top open edge of a pocket. To the immediate right of the dual pockets  31  and  32 , a first enlarged pocket  44  is provided. The bottom edge  46  of this pocket is located proximate the openings of the dual pockets  31  and  32 . This enlarged pocket  44  spans the entire height of the bag body  14  and measures approximately 14 inches in depth. As with the dual pockets, the first enlarged pocket is provided with a top edge  48  providing an opening facing the right hand end  27  of the bag body  14 . A closure device in the form of a nylon zipper  50  may be used to seal off this pocket.  
      With continued reference to  FIG. 1 , spaced to the right of the first enlarged pocket  44  is a pair of intermediate pockets  52  and  54 . These pockets are constructed identically and each measure about 4.75 inches in depth and span the entire height of the bag body  14 . The bottom edge  56  of the first intermediate pocket  52  is conjoined with the top edge of the zipper closure  50 . The top edge  58  of the first intermediate pocket faces the right hand end  27  of the bag body. The second intermediate pocket  54  includes a bottom edge  60  spaced to the right of the top edge of the first intermediate pocket and an opening  62  that faces the right hand edge of the bag body as well. In this example, each of the intermediate pockets  52 ,  54  incorporate hook and loop closures as indicated by strips  53 ,  55 , respectively, to seal off their respective contents. As with the dual pockets  31 ,  32 , each intermediate pocket includes a pull tab  63 ,  65  respectively to assist in separating the hook and loop closures lining the opening of the intermediate pockets.  
      Still referring to  FIG. 1 , the rightmost pocket  64  is a second enlarged pocket and includes a bottom edge  66  corresponding with the right hand edge  27  of the bag body  14 . Unlike the other pockets, the top opening  68  of this pocket faces to the left hand side  25  of the bag body, as viewed in  FIG. 1 . The second enlarged pocket includes a zipper closure  70  for controlling access to the pocket compartment. The second enlarged pocket  64  also spans the entire height of the bag body and measure approximately 11 inches in depth in this exemplary pocket configuration.  
      The pockets  31 ,  32 ,  44 ,  52 ,  54 , and  64  may be formed by sewing, adhering, welding or using other suitable joining techniques to join the three sides of a substantially rectangular plastic sheet or sheets to the interior surface  28  of the bag body  14 . As described above, a fourth edge of the plastic sheet forms an opening into the respective pocket compartments that may be closed using conventional closure devices such as plastic or metal zippers, hook and loop closures, buttons, snaps, and other suitable closure device. It is not necessary to use a closure device however. It is preferable to use clear plastic sheets to form a viewing window, such as exemplified by reference numeral  72  ( FIG. 4 ), so that the contents of the pocket may be easily ascertained without having to open the pocket and remove the contents one at a time until the desired article is retrieved. Other suitable materials may be used as well and the viewing window may comprise the entire pocket wall or a portion thereof. To maximize the storage capacity of the bag body, it is also preferable to provide pockets across the entire width and height of the bag body  14 . However, other pocket configurations will occur to one of ordinary skill in the art. In this example, all of the pocket openings are configured substantially parallel to the left and right hand edges  25 ,  27 , respectively, of the bag body.  
      The pockets may be spaced apart from one another to accommodate folding of the bag body  14  as well. For instance, there are three folding wells in this exemplary bag body  14  as illustrated in  FIG. 1 . The first or leftmost folding well  74  is spaced between the top edges  36 ,  38  of the dual pockets  31 ,  32 , respectively, and the bottom edge  46  of the first enlarged pocket  44 . An intermediate folding well  76  is interposed between the top edge  58  of the first intermediate pocket  52  and the bottom edge  60  of the second intermediate pocket  54 . The rightmost or third folding well  78  is positioned between the opening  62  of the second intermediate pocket  54  and the zipper closure  70  of the second enlarged pocket  64 . In this example, these wells span the entire height of the bag body and measure about 1.5 inches across. These wells provide fold lines that accommodate folding the bag body even when the individual pockets are relatively full and may resist folding themselves.  
      It is also preferable to construct the bag body  14  from waterproof materials or at least highly water resistant materials such as nylon, polyester, or other suitable material. As an alternative, the materials or fabrics used to construct the bag body may be treated with a waterproofing substance. This prevents personal articles that may leak from spreading to the remainder of the bag body or sleeping bag  12  when the rollup pack is in contact with the bag. In addition, a wet towel may be placed in one the pockets without concern of dampening the other articles or sleeping bag. By providing a waterproof exterior surface  26 , the items in the pockets and sleeping bag are further protected from exterior moisture. In addition, if the contents of the bag body  14  are removed or there is no concern if they are compressed, the rollup pack may be used as a mat underneath the sleeping bag  12  when unrolled further protecting the sleeping bag and providing an insulating surface beneath the sleeping bag.  
      Referring now to  FIG. 2 , on the exterior surface  26  of the bag body  14  includes a pair of carrying handles  80  and  82 . The ends of each carrying handle are sewn to the top edge  21  and bottom edge  23  of the bag body  14 . These carrying handles are approximately 22 inches in length to provide ample length for use as shoulder straps in addition to be used as carrying handles. In this exemplary embodiment, the shoulder straps  80  and  82  are spaced approximately 8.75 inches from the respective left end  25  and right end  27  of the bag body  14 . The handles may be adjustable using a conventional shoulder strap adjustment construction. The shoulder straps are preferably constructed of a webbed strapping and may be padded. In general, the shoulder straps divide the intermediate carrying section  16  from the lateral wings  18  and  20 , respectively. However, this division is for ease of description and not meant to be limiting in any manner.  
      With continued reference to  FIG. 2 , a first pair of pack fasteners  84 ,  86  is sewn into the exterior surface  26  of the bag body  14 . The pack fasteners  84  and  86  include a length of webbed strapping  85 ,  87 , respectively, measuring approximately 10.75 inches in length from an interior end fastened to the exterior surface  26  within the intermediate carrying section  16  to the left hand edge  25  of the bag body  14 . Each fastener  84 ,  86  projects approximately 1-2 inches beyond the left most edge  25  of the bag body and terminates in a plastic clip  88 ,  90 , respectively, of the dual bayonet variety. The fasteners  84  and  86  are spaced apart approximately 6.5 inches along the height of the bag body. The strap portions  85  and  87  of the fasteners are constructed from a similar webbed strapping material as the shoulder straps  80  and  82 .  
      With continued reference to  FIG. 2 , on the right hand side of the bag body  14  is a second pair of pack fasteners  92 ,  94  constructed in a similar manner to the first pair of pack fasteners  84 ,  86  with a strap section  93 ,  95 , respectively, sewn into the exterior surface  26  of the bag body. The ends of the pack fasteners  92 ,  94  project approximately 1-2 inches beyond the right hand edge  27  of the bag body and terminate in a plastic buckle  96 ,  98 , respectively, for fastening to the clips  88 ,  90  of the first pair of pack fasteners when the wings  18  and  20  are brought together. As viewed in  FIG. 2 , upper first fastener  84  is aligned with upper second fastener  92  along the height of the bag body when the bag body is rolled out flat. Lower first fastener  86  is aligned with lower second fastener  94  in a similar configuration. These fastener pairs may be adjustable as well to accommodate a variety of sleeping bag dimensions. This exemplary embodiment describes a two pair of pack fasteners in the form of a clip and buckle. It will be appreciated that other suitable releasable fastening devices may be used as well including hook and loop closures, snaps, buttons, rings, clamps, hooks and grommets, or loose tie ends.  
      With reference now to  FIGS. 1-4 , in use, the rollup pack  10  is laid out flat on a bed or other convenient flat surface. The user may then grasp the tabs  40 ,  42 ,  63 ,  65  of the desired pocket  31 ,  32 ,  52 , and  54 , respectively, to separate the hook and loops and closures or unzip the zipper closures  50 ,  70 , of the enlarged pockets  44 ,  64 , respectively, to open the desired pocket  30 ,  32 ,  44 ,  52 ,  54 , and  64  insert extended stay articles such as clothing, footwear, toiletries, snacks, reading materials, and other suitable items to be taken on an overnight trip in a manner of organization as befitting the user. Exemplary articles such as a toothpaste tube  104   a , toothbrush  104   b , pajamas  104   c , hairclips  104   d , socks  104   e , brush  104   f , comb  104   g , and sandals  104   h  are illustrated in  FIG. 4 . When the desired overnight articles have been inserted into the pockets, the opening of the pockets are closed by mating the hook and loop closures or zipping the zipper closures where appropriate.  
      Turning now to  FIGS. 5A-5C , the user may then roll up the sleeping bag  12  into a cylindrical configuration such as illustrated in  FIG. 5A  and place the rolled up sleeping bag on top of the interior surface  28  of the bag body  14  of the rollup pack  10  about the middle of the bag body. The flat ends of the sleeping bag are generally aligned with the top edge  21  and bottom edge  23  of the bag body but may extend beyond or fall short of the edges as determined by the relationship of the rolled up sleeping bag height in relation to the rollup pack height. The user may then grasp the left wing  18  by the left hand end  25  and fold it on top of the sleeping bag to partially wrap the wing about the circumference of the sleeping bag. Even with the pockets being filled to capacity and possibly resistant to bending, the left wing will fold about the well  74  onto to the sleeping bag and generally follow the curvature of the sleeping bag. Then, the user may grasp the right hand edge  27  of the bag body and bring the right wing  20  and its buckles  96 ,  98  proximate their respective counterpart clips  88 ,  90  of the first pair of pack fasteners  84 ,  86 , respectively. Clip  88  is then inserted into buckle  96  and clip  90  is inserted into buckle  98 . This action secures the left wing  18  to the right wing  20  and secures the sleeping bag  12  within the rollup pack  10  to from an integral unit, generally designated  100 , for transportation as illustrated in  FIG. 5C . The right wing may be inserted above or below the left wing about the sleeping bag as long as the fasteners are exposed and may be coupled together. Preferably, the wings overlap when the ends of the rollup pack are fastened together so that there are no gaps around the circumference of the sleeping bag ( FIG. 5C ). This is facilitated by attaching the fastener straps at their extreme inner ends (X-patterns in  FIG. 2 ) to the exterior surface  26  of the rollup pack  10  while leaving the remainder of each strap length unattached to the rollup pack. The fastener straps may be adjusted as necessary to tighten the rollup pack  10  about the sleeping bag  12 . Given the adjustability of the straps, it is not necessary to roll up the sleeping bag the same way every time and a variety of sleeping bags may be accommodated. The user may then don the rollup pack unit  100  as one would a backpack by slipping left and right arms through the corresponding shoulder straps  80  and  82  and carry the integrated unit  100  on the user&#39;s back. Alternatively, the user may grasp both straps with one hand and carry as a piece of luggage.  
      Once the integrated unit  100  has been transported to the desired destination, the user may set the unit on a relatively elongated flat surface and separate clip  88  from buckle  96  and separate  90  from buckle  98 . The user may then peel back the right wing  20  from the left wing  18  exposing the sleeping bag  12  and laying the rollup pack  10  flat. The sleeping bag may then be moved off to a side and the contents of the rollup pack  10  accessed as desired. The viewing windows  72  of each pocket facilitate the removal of the desired articles  104   a ,  104   b ,  104   c ,  104   d ,  104   e ,  104   f ,  104   g ,  104   h  in an organized manner.  
      It will be appreciated that the interior facing pockets  30 ,  32 ,  44 ,  52 ,  54 , and  64  and sleeping bag  12  cooperate to cushion the articles stored in the rollup pack during transportation. In addition, the vertical and inwardly facing openings of each pocket reduce the likelihood of any articles falling out of a pocket during transport. The interior facing pockets also reduce the likelihood of theft of important articles during transport. In addition, in this exemplary embodiment, the rollup pack is described as being flexible throughout its length. However, the medial section may include a rigid insert  102  ( FIG. 2 ) or be formed of a formed foam or other cushioning material to conform to the user&#39;s back and the curved sleeping bag with the wing wraps remaining flexible to wrap about the substantially cylindrical object being transported.  
      Instead of a sleeping bag  12 , a beach towel, rolled up cushion, mat or other similar cushioning article may be rolled up into a substantially cylindrical configuration, folded up, or otherwise flattened and the portable pack secured around the article for transport to the beach, gym, or other location. The portable pack may also be used simply as a standalone organizer pack with or without any cushioning article. Moreover, the flexible wing wraps of the portable pack easily accommodate cushioning articles arranged in a folded up configuration as well. The wing wraps of the portable pack may be folded over the article and locked together to secure the article in place and present a smaller profile portable pack. In packing the portable pack, the cushioning article may be pre-folded and placed on one of the storage sections of the laid out pack prior to folding the wing wraps or the article may be simply be placed over the laid out pack and folded along with the pack itself.  
      Referring now to  FIGS. 6-16 , a second embodiment of the portable rollup pack adapted for use as a diaper changing accessory organizer, generally designated  210 , is illustrated. Like the previously described embodiments of the portable rollup pack  10 , the diaper changing accessory organizer provides a convenient portable travel pack for organizing, storing, and transporting personal articles. In addition, the portable diaper changing accessory organizer is constructed to be particularly useful for transporting personal articles along with those items required for changing a baby. Moreover, this exemplary portable organizer  210  is constructed to releasably secure and transport rolled up, flattened, or folded objects such as a diaper changing mat or pad, generally designated  212  ( FIG. 8 ), on which a baby may be changed, and thus provides a convenient diaper changing station as well. As noted above, this exemplary portable organizer  210  shares many of the same features with previously discussed embodiments of the rollup pack and like components are like numbered.  
      Before continuing further with the description of the portable diaper changing accessory organizer  210 , attention is directed to  FIGS. 6 and 8  wherein the exemplary two-sided diaper changing mat is illustrated. More particularly, the diaper changing mat is generally rectangular with rounded corners and includes a top edge  241 , a bottom edge  243 , a left hand edge  245  (as viewed in  FIG. 6 ), and a right hand edge  247 . The outer edges of the mat are finished with a stitched piping  229  around the periphery of the mat. When unfolded, the top edge  241  of the mat generally coincides with the baby&#39;s head while the bottom edge  243  coincides with the baby&#39;s feet but this is only for reference purposes and not meant to be restrictive. Regarding placement of the infant, it will be appreciated that the oversized mat, with dimensions approaching a square shape, allows the user to place the infant on the mat in any suitable way convenient for the user including vertically, horizontally, or diagonally in either direction with respect to the underlying organizer bag body  214 , something a more narrow elongated mat restricted to a particular orientation would be lacking.  
      The changing mat  212  includes a changing surface  215  ( FIGS. 6 and 9 ) and an opposing attachment surface  217  ( FIG. 8 ). On the attachment surface  217 , an elongated, rectangular anchor strip  219   a  is positioned halfway between the left and right hand edges  245 ,  247 , respectively, of the diaper changing mat with the outer end of the strip being positioned approximately an inch from the top edge  241  of the mat. The length of the strip is approximately 4-6 inches. In this exemplary embodiment, the diaper changing mat  212  measures approximately 21 inches long from the top edge  241  to the inner edge  243  and approximately 23 inches wide from the left hand edge  245  to the right hand edge  247 . The length of the diaper changing mat  212  preferably coincides with the distance between the outer edge  225  of the diaper bag body  214  and the nearer edge of an intermediate fold well  276   a  described below. The width of the mat is almost double the width of the bag body (12.5 inches) so that the mat may be opened out to almost twice the width of the bag body and only require each side being folded once to fit within the confines of the bag body. Other suitable mat dimensions will occur to one of ordinary skill in the art including a diaper mat that fits within the confines of the diaper bag body without being folded. While an infant may be changed directly on top of the portable organizer or other underlying surface, the inclusion of the mat provides a preferred changing surface and transforms the diaper changing accessory organizer into a more suitable changing station.  
      Returning to the description of the portable diaper changing accessory organizer  210 , when unfolded and laid flat in a pre-packing or changing station configuration as in  FIGS. 6-7 , the portable diaper organizer  210  generally includes a substantially rectangular bag body  214  that may be divided generally into a common central section  216  interposed between a left lateral storage section  218  (as viewed in  FIG. 6 ) and a right lateral storage section  220  that provide storage and organizational features as described below. The bag body is constructed of an outer layer of fabric  222  sewn or welded to a similarly dimensioned inner layer of fabric  224  defining an exterior bag body surface  226  and interior bag body surface  228 , respectively. The top edge  221 , bottom edge  223 , left hand edge  225 , and right hand edge  227  of the bag body are then finished off with conventional ¼ inch filled piping  230  circumscribing the perimeter of the bag body. In this exemplary embodiment, the overall length and width dimensions of the rectangular organizer bag body  214  are similar to the previous pack embodiment  10  discussed above.  
      With continued reference to  FIG. 6 , the interior surface  228  of the organizer bag body  214  may be conveniently divided into a number of pockets for organizing, storing, and transporting both personal articles and diaper changing accessories. In this exemplary embodiment, the organizer bag body includes seven pockets arranged across substantially the entire length and height of the diaper bag body. As viewed in  FIG. 6 , the left storage section  218  includes an upper pocket  231  and a lower pocket  232 . These leftmost pockets are vertically stacked and together span the entire height of the diaper bag body. In this exemplary embodiment, these dual pockets also subdivide the height of the diaper bag body equally. These dual pockets include a common bottom edge  234  that corresponds with the leftmost edge  225  of the bag body as viewed in  FIG. 6  and a common sidewall  235 . Each pocket  231 ,  232  also includes a vertically projecting top edge  236 ,  238 , respectively, forming an opening into the respective pocket. The openings face the right hand end  227  of the bag body. The top edges of the pockets  231 ,  232  may be lined with a conventional hook and loop type closure as indicated by strips  237 ,  239 , respectively, to seal off the contents of the pocket. A convenient pull tab  240 ,  242  is provided on each pocket  231 ,  232 , respectively, to facilitate separating the hook section from the loop section to gain access to the pocket. These dual pockets  231  and  232  are typically dimensioned to accommodate smaller personal articles such as baby shoes and socks. In this exemplary embodiment, these dual pockets measure approximately 7.5 inches in depth from the bottom edge  234  of each pocket to the top opening edge  236  or  238 , respectively.  
      The common sidewall  235  of the dual pockets  231 ,  232  bears a second anchor strip  219   b  complementing the changing mat anchor strip  219   a . The anchor strips  219   a ,  219   b  of the bag body  214  and the changing mat  212  are preferably conventional hook and loop fasteners for releasably securing the changing mat  212  to the diaper bag body  214  and are interchangeable. The common sidewall  235  of the dual pockets forms a slight depression in the middle of the organizer bag body within the leftmost storage section  218  that becomes more pronounced when articles are stored in the dual pockets. Such depression may be located beneath the child&#39;s head when in use and thus may assist in keeping the child centered on the mat.  
      Still referencing  FIG. 6 , to the immediate right of the dual pockets  231  and  232 , a first enlarged pocket  244  is provided on the left hand side of the common central section- 216 . The bottom edge  246  of this pocket is located proximate the openings of the dual pockets  231  and  232 . This enlarged pocket  244  spans the entire height of the bag body  214  and measures approximately 14 inches in depth. As with the dual pockets  231 ,  232 , the first enlarged pocket is provided with a reinforced top edge  248  providing an opening facing the right hand end  227  of the bag body  214 . A closure device in the form of a nylon zipper  250  is used to seal off this pocket.  
      Positioned to the right of the first enlarged pocket  244  on the right hand side of the common central section  216  as viewed in  FIG. 6  is an intermediate quick retrieval pocket section  252 . The quick retrieval pocket section is formed by sewing three sides of an expandable mesh retainer  253  into the interior surface  224  of the organizer bag body  214  and leaving the edge facing the top edge  221  of the organizer bag body free to form a top opening pocket. The mesh retainer is also sewn at two intermediate points to the interior surface  224  to further subdivide the mesh retainer into three expandable pockets  254   a ,  254   b , and  254   c . An expandable, elastic band  258  extends horizontally across the bag body  214  within the pocket section  252  parallel to the top and bottom edges  221 ,  223  of the diaper bag body and provides common top edge for all three expandable pockets. This top opening edge is recessed below the upper edge of the diaper bag body. In this example, the top edge band  258  is positioned closer to the top edge  221  of the organizer bag body  214 . The bottom edge  256  of the mesh pockets  254   a - c  is aligned with the bottom edge  223  of the organizer bag body  214 . These mesh pockets measure approximately 4.75 inches deep and span the entire width of the bag body  214  between the first enlarged pocket  244  and the rightmost enlarged pocket  264  described below.  
      While the tension of the band  258  assists in securing articles within these pockets  254   a - c , articles stored in the mesh pockets may be quickly withdrawn without having to unfasten a closure device once the pack is laid flat. Thus this quick retrieval pocket section  252  is useful for storing items such as clean diapers, wipes, and bottles that may have to be accessed quickly. The see-through mesh also enables the user to quickly identify the contents of these pockets.  
      Still referring to  FIG. 6 , the rightmost pocket  264  is a second enlarged pocket similar in construction to the first enlarged pocket  244 . The rightmost pocket includes a bottom edge  266  corresponding with the right hand edge  227  of the bag body  214 . Unlike the other pockets ( 231 ,  232 ,  244 ), the top opening  268  of this pocket faces the left hand side  225  of the bag body, as viewed in  FIG. 6 . The second enlarged pocket includes a zipper closure  270  for controlling access to the pocket compartment through the top opening  268 . The second enlarged pocket  264  also spans the entire height of the bag body and measure approximately 11 inches in depth in this exemplary pocket configuration.  
      The sections  216 ,  218 , and  220  of the organizer bag body  214  may be spaced apart from one another and joined together by a pivotal or hinged connection to accommodate folding of the bag body  214 . For instance, there are three fold wells or pivotal connections in this exemplary bag body  214  as illustrated in  FIG. 6 . The first or leftmost pivotal connection  274  is spaced between the top edges  236 ,  238  of the dual pockets  231 ,  232 , respectively, and the bottom edge  246  of the first enlarged pocket  244 . An intermediate pivotal connection  276   a ,  276   b  is interposed between the top edge  248  of the first intermediate pocket  244  and the left hand end  260  of the mesh pocket section  252  at two locations to either side of the zipper closure  250 . The rightmost or third pivotal connection  278   a ,  278   b  is positioned between the right hand end  262  of the mesh pocket section  252  and the top edge  268  of the second enlarged pocket  264  and occurs at two locations to either side of the zipper closure  270 . In this example, these pivotal connections span the entire height of the organizer bag body and measure about 1.5 inches across. These pivotal connections provide gaps between the pockets that accommodate folding the bag body even when the individual pockets are relatively full and may resist folding themselves. Thus, the fold wells provide a pivotal or hinged connection between adjacent sections ( 216 ,  218  and  216 ,  220 ) or within a section  216  itself. The fold wells may be a narrow crease or region, depression, fold line, or a more broadened region on the organizer bag body positioned between adjacent pockets to allow the sections of the organizer bag body to be bent, pivoted, or folded about the folding area.  
      Referring now to  FIG. 7 , the exterior surface  226  of the bag body  214  includes a two-piece shoulder strap  284   a ,  284   b  for use in carrying the organizer  210  when in a folded configuration as discussed below. The first section  284   a  of the shoulder strap includes a first end sewn into the bottom edge  223  of the diaper bag body and a distal end that terminates in a bayonet clip  285   a . The second section  284   b  of the shoulder strap includes a first end sewn into the top edge  221  of the diaper bag body and a distal end that terminates in a complementary buckle  285   b  for receiving the bayonet clip. When clipped together, the shoulder strap is approximately 22 inches long. However, the strap includes an adjuster  286 . The adjuster is a conventional retaining slide to adjust the length of a shoulder strap and its use and construction will be familiar to one of ordinary skill in the art. The shoulder strap is preferably constructed of a webbed strapping and may be padded. In general, the shoulder strap is located at the center of the organizer bag body and coincides with the central pivotal connection  276   a ,  276   b.    
      With continued reference to  FIG. 7 , to the left of the shoulder strap  284   a ,  284   b , a pair of stroller retention straps  280   a ,  280   b  are sewn by their respective midsections into the exterior surface  226  of the bag body  214 . The stroller straps include a length of webbed strapping similar to that used for the shoulder strap. Each stroller strap measures approximately one-half inch wide and 5-6 inches in length and includes opposing free ends with complementary fasteners that may fastened to one another to form a loop as shown in  FIGS. 7, 14 , and  15 . A view of the stroller straps in an unfastened configuration is illustrated in  FIG. 16 . In this exemplary embodiment, the fasteners are snaps but other suitable fasteners may be used. The stroller straps are spaced apart approximately 6-8 inches between the top and bottom edges  221 ,  223  of the diaper bag body. Such stroller straps provide a convenient loops for fasteners over a conventional stroller handle (not shown) to retain the diaper bag thereon.  
      With continued reference to  FIG. 7 , an elastic retaining band  294  is provided. The elastic band is approximately a ¼ inch in diameter and has an overall length of 13 and ⅜ inches. As shown in  FIG. 6  in phantom lines, the retaining band is positioned to the right of the leftmost fold well or pivotal connection  274  and to the left of the intermediate pivotal connection  276   a ,  276   b . Each end of the band is sewn into the top and bottom edges  221 ,  223 , respectively, of the organizer bag body  214 . The band is used to capture an opposing folded section of the organizer bag body to maintain the organizer bag body in a folded configuration as will be described below.  
      Still referring to  FIG. 7 , positioned between the shoulder strap  284   a ,  284   b  and the retaining band  294  is an external security pocket  288  for storing items such as keys, credit cards, cell phones, and other items commonly stored in a carrying purse. The bottom edge of the security pocket  289  is located approximately one inch from the retaining band  294 . The side edges of the security pocket are recessed from the top and bottom edges  221 ,  223  of the organizer bag body  214 . Recessed from the top edge  295  of the security pocket is a zipper closure  293  for sealing off the security pocket. The security pocket is further conveniently divided into a cell phone pocket  290  and a credit pocket  292  as shown in phantom lines in  FIG. 14  lining the inside surface of the security pocket providing further organizational capabilities. The security pocket is positioned on the exterior  226  of the organizer bag body to face outwardly when the organizer  210  is folded as will be described below. The security pocket may lay flat against the organizer bag body for carrying substantially flat items or may be expandable to accommodate larger articles.  
      In use, assuming the diaper changing accessory organizer  210  is initially empty and its pockets closed, a user may initially lay the diaper bag organizer and changing station  210  on a flat surface with the primary storage pockets  231 ,  232 ,  244 ,  254   a - c ,  264  facing up as in  FIG. 6 . Each of the zippered pockets  244 ,  264  may be opened by grasping the zipper tabs of the respective zippers  250 ,  270  and pulled in the open direction. The pull tabs  240 ,  242  of the dual pockets may be pulled away from the organizer bag body  214  to open the dual pockets  231 ,  232 , respectively. Articles such as diapers, wipes, spare clothes, powder, ointments, medicines, baby toys, bottles, and other typical baby changing or comfort articles may be inserted into any of the open pockets as befits the user. Some of these exemplary articles  291   a - e  are illustrated in pockets  254   a ,  254   b  and  264 . It will be appreciated that most of these articles lay relatively flat. For example, one suitable arrangement is to place softer good such as clothes and the like in the pockets  231 ,  232 , and  244  that will underlie the changing mat  212  so that the baby can lay on this area when being changed without discomfort. Conveniently, items needed for changing the baby such as diapers, wipes, and bottles may be located in pockets  254   a - c  in the quick retrieval section  252 . Other items needed during the changing process may be stored in the rightmost pocket  264  as both the quick retrieval pockets  254   a - c  and the rightmost pocket  264  are typically uncovered during the changing process. In addition, one or more of the pockets may be left empty to receive and keep separate soiled or dirty clothes. Other suitable packing arrangements will occur to the user.  
      With reference to  FIGS. 6, 8 , and  9 , once the diaper changing bag  210  is packed with the accessories and the respective closures are fastened, the top edge  241  of the diaper changing pad  212  may be aligned with the left hand end of the organizer bag body  214  so that the main surface  215  of the changing pad covers the pockets  231 ,  232 , and  244  of the left storage section  218  and a significant portion of the common central section  216 , respectively, while leaving the quick retrieval pockets  254   a - c  of the other portion of the common central section and pocket  264  of the right storage section  220  exposed. This placement of the changing pad will also closely align inner edge  243  of the changing pad with the zipper closure  250  ( FIG. 6 ) of the first enlarged pocket  244  without interfering with the intermediate pivotal connection  276   a ,  276   b . By centering the pad vertically on the bag body, the complementary hook and loop fasteners  219   a ,  219   b  of the changing mat and organizer bag body will also be aligned. The changing pad may then be pressed onto the organizer bag body to mesh the complementary hook and loop fasteners and releasably retain the changing pad to the organizer bag body.  
      With the changing pad  212  secured to the organizer bag body  214 , the lower edge  245  of the diaper changing pad  212  may be folded upwardly onto itself so that the lower edge  245  of the diaper changing pad as viewed in  FIG. 10  falls onto the proximate center of the diaper changing pad. In this manner, the lower folded edge of the diaper changing pad coincides with the bottom edge  223  of the diaper bag body ( FIG. 10 ). In a similar manner, the upper edge  247  of the diaper changing pad as viewed in  FIG. 11  may be folded downwardly to bring the upper edge proximate the folded lower edge  245  and near the center of the diaper changing pad as shown in  FIG. 11 . The upper folded edge of the diaper changing pad will now coincide with the top edge  221  of the diaper bag body. As shown in  FIG. 11 , the opposing edges  245  and  247  of the changing mat  212  may be slightly spaced apart but this may vary depending on the dimensions of the changing mat.  
      Referring now to  FIG. 12 , the user may grasp the outer edge  225  of the organizer bag body  214  and fold, bend, or pivot the left storage section  218  upwardly from the underlying surface and to the right about a vertical axis passing through the length of the left pivotal connection  274  and onto the interior surface of the left portion of the common central section  216  ( FIG. 6 ). In this exemplary embodiment, fully pivoting the left storage section  218  onto the common central section forms a first overlapping region  298   a  also referred to as a folded or bent wing with the elbow of the wing being the outermost edge of the folded region. In this configuration, the folded outer edge  225  of the diaper bag body will be spaced a few inches to the left of the central fold well  276   a ,  276   b . It will be appreciated that the flexible diaper changing mat  212  is folded along with the organizer bag body. If a diaper changing mat is not used, then the interior surface of the left storage section  218  will abut the interior surface of the left portion of common central section  216  when fully folded again resulting in a first overlapping region.  
      In a similar manner, the user may grasp the right hand outer edge  227  of the organizer bag body  214  and pivot the right storage section  220  upwardly and to the left about a vertical axis passing through the length of the rightmost pivotal connection  278   a ,  278   b  and onto the right hand portion of the common central section  216  to form a second overlapping region  298   b  ( FIG. 13 ) such that the interior surface  224  of the right storage section is brought into contact with a right hand portion of the interior surface  224  of the common central section. In addition, the right hand edge  227  of the bag body is brought to rest to the right of the central pivotal connection  276   a ,  276   b  and spaced apart from the folded left hand edge  225 . As shown in  FIG. 13 , the exterior surface  226  of the left and right overlapping regions  298   a ,  298   b , respectively, and a reduced portion of the interior surface  224  of the common central section  216  are facing the user. Alternatively, the outer storage sections  218  and  220  may be folded onto the common central section  216  to form the overlapping regions at the same time or in reverse order as well. In addition, while it is preferred that the ends  225 ,  227  of the organizer bag body are spaced at least slightly apart when the outer storage sections  218 ,  220  are folded onto the common central section  216  to accommodate the subsequent folding step, a minor amount overlap may occur without detracting from the use of the bag due to the flexible construction of the bag body.  
      Referring now to  FIGS. 13-16 , the user may then fold the common central section  216  along a vertical axis that is parallel to the axes of the outer pivotal connections and passes through the length of the central fold well  276   a ,  276   b  to bring the opposing overlapping regions  298   a  and  298   b  and their respective folded storage sections  218  and  220  together with the exterior surface  226  of the left storage section  218  abutting at least a portion of the exterior surface  226  of the right storage section  220  to form a relatively thin profile transportable organizer ( FIGS. 14-16 ). To capture and maintain the opposing overlapping regions together, the user may grasp the elastic restraining band  294  and pull it downwardly from the overlapping region  298   a  and loop the band around the opposing overlapping region  298   b  and then release the band to secure the overlapping regions  298   a  and  298   b  together as shown in  FIG. 16 . The tension of the capturing band maintains the overlapping regions in an abutting relationship and readies the organizer bag body  214  for transportation. It will also be appreciated that the diaper changing accessories and diaper changing mat  212  are secured inside the folds of the bag and will not fall out.  
      With the bag in a fully folded or transportation configuration as in  FIGS. 14-16 , the user may open the zipper closure  293  of the exterior security pocket  288  and load the security pocket and internal cell phone pocket  290  and credit card pocket  292  with the appropriate items. The zipper closure may be closed when finished loading the external pocket  288 . For example, various items such as credit cards, identification, passports, keys, and the like may be inserted into the exterior pockets. If not already secured together, the bayonet clip  285   a  may be inserted into the buckle  285   b  to couple the shoulder strap sections  284   a ,  284   b  together. The combined diaper changing organizer and changing station  210  may then be worn on the user&#39;s shoulder as with a conventional shoulder bag with the security pocket facing outwardly from the user&#39;s body. Alternatively, the user could flip the bag around so that the security pocket is against the user&#39;s body to dissuade thievery even further. The shoulder strap may be adjusted using the adjuster  286  by the user if necessary using conventional methods. Alternatively, if a stroller is to be used, the user may open the stroller straps  280   a ,  280   b  by unfastening their respective fasteners. The free ends of each stroller strap may be looped over the handle bar of the stroller and refastened around the handle bar. The diaper changing organizer and changing station  210  may then be suspended from the stroller handle bar in this manner.  
      Once the diaper bag organizer and changing station  210  has been transported to the desired destination, the user may slip the organizer off the user&#39;s shoulder or unfasten the organizer from the stroller and place the organizer bag body  214  on a relatively elongated flat surface on one side. The restraining band is pulled off the captured folded section  298   b  and returned to its original position. The user may then unfold the organizer and the diaper changing mat  212  by simply reversing the folding steps above until the configuration in  FIG. 9  is reached.  
      With continued reference to  FIG. 9 , it will be appreciated that the organizer is unfolded with just a few quick movements to expose the changing mat. The mat itself only requires a couple of quick flips to unfold completely. It will further be appreciated that every accessory needed to change the baby is exposed in the quick retrieval mesh pockets  254   a - c  and second enlarged pocket  264  during the unfolding process. The user may lay the infant down on the diaper changing mat  212  with the infant&#39;s head placed substantially over the anchoring strips  219   a ,  219   b , which is the approximate midpoint between the left hand and right hand edges  245 ,  247  of the changing mat. This will also center the infant&#39;s head over the depressed area formed by the common sidewall  235  of the dual pockets  231 ,  232  and help to maintain the infant in a centered position on the mat. As the changing mat  212  is secured to the diaper bag body  214 , no relative slippage will occur. The user may then perform a routine diaper changing using accessories from the quick retrieval pockets  254   a - c . Other accessories as needed may be retrieved from the second enlarged pocket  264 . The viewing windows  272  of each pocket facilitate the removal of the desired articles in an organized manner. In addition, prior to placing the infant on the changing mat, the user may elect to remove the changing mat from the diaper bag body  214  by separating the anchor strips  219   a ,  219   b  to access the pockets  231 ,  232 , and  244  beneath the mat, if necessary. The mat may then be replaced and the infant changed as before.  
      Referring now to  FIGS. 17-24 , a more secure and rigid embodiment of the diaper changing accessory organizer, generally designated  310 , is illustrated, as in some instances a more rigid bag configuration is preferred, particularly when the combined weight of the diaper changing accessories is significant. This exemplary diaper bag organizer is constructed alike and shares many of the same features with the previously discussed embodiments and like components are like numbered. The primary differences between the prior organizer embodiment  210  and the presently described organizer  310  involve the pocket arrangements, anchor strip location, and some added stiffness and security features that will now be described.  
      Referring now to  FIG. 19 , the changing mat  312  of the second organizer embodiment  310  is constructed similarly to the changing mat  212  and like features are numbered alike. The dimensions of the two mats are the same. The only difference is that the length of the elongated, rectangular anchor strip  319   a  on the diaper changing mat  312  is approximately the same as the overall height of the organizer bag body  314  from the top edge  321  to the bottom edge  323  thus provided an elongated anchoring surface over the previously described changing mat for a more secure attachment.  
      When laid flat as in  FIG. 17 , the bag body  314  of the organizer  310  may be divided generally into left storage section  318  and a right storage section  320  with a common central section  316  therebetween. In this exemplary embodiment, the overall length and width dimensions of the rectangular diaper bag body  314  are similar to the previous pack embodiments  14 ,  214  discussed above.  
      Extending from the leftmost edge  325  of the left storage section  318  is a set of left hand retention flaps  349   a ,  349   b  as viewed in  FIG. 17 . The retention flaps are spaced several inches apart along the leftmost edge  325  of the bag body  314 . Each flap includes a fastener element  351   a ,  351   b . Similarly, a set of spaced apart right hand retention flaps  353   a ,  353   b  extend outwardly from the rightmost edge  327  of the bag body with each flap including a fastener element  355   a ,  355   b . These retention flaps are used to secure the respective folding wings to bag body when folded as will be described in more detail below.  
      With continued reference to  FIG. 17 , the diaper bag body  314  includes seven pockets  331 ,  332 ,  344 ,  354   a - c , and  364  arranged across substantially the entire length and height of the diaper bag body. These pockets are similar in construction to the previous embodiment but laid out in a different configuration to illustrate the versatility of the diaper bag organizer. More specifically, the pocket configurations of the left hand and right hand storage sections  318 ,  320 , respectively, have been swapped in this example with the dual pockets openings facing one another instead of sharing a common sidewall. More specifically, the left storage section  318  includes the first enlarged pocket  344  instead of the dual pocket arrangement of the previous embodiment. The bottom edge  346  of this pocket is located proximate the first or leftmost pivotal connection  374 . This enlarged pocket  344  spans the entire height of the bag body  314  and measures approximately 14 inches in depth. The first enlarged pocket is provided with a reinforced top edge  348  providing an opening facing the left hand end  325  of the bag body  314 . A closure device in the form of a nylon zipper  350  is used to seal off this pocket.  
      Still referring to  FIG. 17 , to the immediate right of the first enlarged pocket is a second enlarged pocket  364  similar in construction to the first enlarged pocket  344 . The rightmost pocket includes a bottom edge  366  corresponding with the leftmost pivotal connection  374 . The top opening  368  of this pocket faces to the right hand side  327  of the bag body, as viewed in  FIG. 17 . The second enlarged pocket includes a zipper closure  370  for controlling access to the pocket compartment through the top opening  368 . The second enlarged pocket  364  also spans the entire height of the bag body and measure approximately 11 inches in depth in this exemplary pocket configuration. The second enlarged pocket is located within the common central section  316  of the bag body  314 . In this exemplary embodiment, the first enlarged pocket  344  includes a viewing window  372 . The viewing window  372  of each pocket facilitates the removal of the desired articles in an organized manner. To the immediate right of this pocket  364  is an intermediate quick retrieval pocket section  352  and pockets  354   a - c  constructed in the same manner as the prior organizer embodiment  210  and located on the right hand side of the common central section.  
      Located within the right storage section  320  and to the immediate right of the quick retrieval pocket section  352  are an upper pocket  331  and a lower pocket  332 . These rightmost pockets are vertically stacked and together subdivide the height of the diaper bag body equally. Each pocket  331 ,  332  includes a vertically projecting top edge  336 ,  338 , respectively, forming an opening into the respective pocket. In this exemplary embodiment, the top edges  336 ,  338  of the pockets  331 ,  332 , respectively, face one another and are disposed proximate the mid-line of the bag body  314 . The top edges of the pockets  331 ,  332  may be lined with a conventional hook and loop type closure as indicated by strips  337 ,  339 , respectively, to seal off the contents of the pocket. A convenient pull tab  340 ,  342  is provided on each pocket  331 ,  332 , respectively, to facilitate separating the hook section from the loop section to gain access to the pocket. The depth and width dimensions are reversed from the previously described organizer embodiment.  
      As with the prior embodiment, this exemplary bag body  314  includes three pivotal connections with some modifications. The first pivotal connection  374  is a 1.5 inch wide strip spaced between the bottom edges  346 ,  366  of the first and second enlarged pockets  344 ,  364 , respectively. This pivotal connection or fold well also bears the elongated second anchor strip  319   b  along its length complementing the changing mat anchor strip  319   a . As with the prior embodiment  210 , this pivotal connection forms a slight depression when the adjacent pockets are full and thus may assist in keeping the child centered on the changing mat  312  when in use. Conveniently, the left and right sides of the changing mat  312  may be pivoted on the anchor strips  319   a ,  319   b  when the mat is releasably secured to the bag body  314  like the pages of a book to expose a corresponding underlying pocket  344 ,  364 . In this manner, the user may access the pocket openings  348 ,  368  below as illustrated for example in  FIG. 19  for the first enlarged pocket.  
      An intermediate pivotal or hinged connection with spaced apart edges  376   a ,  376   b  is interposed between the top edge  368  of the second enlarged pocket  364  and the left hand end  360  of the mesh pocket section  352 . Unlike the earlier embodiments, this pivotal connection includes an optional 2-3 inch wide rigid insert or spine  373  shown in phantom lines in  FIG. 17 . This insert is located between the outer and inner sheets of the bag body and provides extra rigidity to the upper surface of the bag body  314  to prevent sagging when in a folded configuration and hung from a user&#39;s shoulder or the stroller. The rigid spine also ensures the bag body folds about the fold lines  376   a ,  376   b  to either side of the spine. Projecting through the spine is a set of vertically spaced apart rivets  375   a ,  375   b  as viewed in  FIG. 17 . These rivets secure the spine insert to the bag body between the outer and inner layers of fabric  322 ,  324  and further secure the stroller straps  380   a ,  380   b  to the exterior surface  326  of the bag body. Located between the rivets are pair of spaced apart wing anchors  377   a ,  377   b . Each wing anchor includes a fastener constructed to receive the complementary fasteners of the corresponding storage section (or wing) retention flaps  349   a ,  349   b ,  353   a ,  353   b . In this exemplary embodiment, the fasteners on the anchors and retention flaps are of the hook and loop variety. The anchors  377   a ,  377   b  are dimensioned to be approximately twice the width of an individual retention flap fastener  351   a ,  351   b ,  355   a , or  355   b  to receive two opposing retention flap fasteners thereon. The top anchor  377   a  is vertically aligned on the bag body  314  with opposing retention flaps  349   a  and  353   a  as viewed in  FIG. 17 . Likewise, the bottom anchor  377   b  is vertically aligned with opposing retention flaps  349   b  and  353   b.    
      Still referring to  FIG. 17 , the rightmost or third pivotal connection  378  is positioned between the right hand end  362  of the mesh pocket section  352  and the bottom common interior edge  335  of the dual pockets  331 ,  332 . This fold well is approximately one-half inch in width and as with each of the pivotal connections, spans the entire height of the bag body  314 .  
      When the diaper changing mat  312  is secured to the diaper bag body  314  by the corresponding anchor strips  319   a ,  319   b , the length of the diaper changing mat  312  coincides with the distance between the outer edge  325  of the diaper bag body  314  and approximately the left intermediate fold well  376   a . The width of the mat is almost double the width of the bag body (12.5 inches) so that the mat may be opened out to almost twice the width of the bag body and only require each side being folded once to fit within the confines of the bag body.  
      Referring now to  FIG. 18 , the exterior surface  326  of the bag body  314  includes similar features as the organizer  210  such as an external security pocket  388  with internal cell phone pocket  390  and credit pocket  392  ( FIG. 22 ), shoulder strap  384 , and stroller straps  380   a ,  380   b . However, in this exemplary embodiment, the shoulder strap  384  is a one-piece strap with a first end sewn into the bottom edge  323  of the bag body and an opposing end sewn into the top edge  321  of the diaper bag body. The shoulder strap includes a similar adjuster  386  as before and also includes an integral shoulder pad  385  that may be conveniently slid along the length of the shoulder strap. In general, the shoulder strap is located at the center of the diaper bag body and coincides with the central spine  373 .  
      With continued reference to  FIG. 18 , between the shoulder strap  384  connections, a pair of stroller straps  380   a ,  380   b  are held in place by their respective midsections on the exterior surface  326  of the bag body  314  by rivets  375   a ,  375   b , respectively. Each stroller strap  380   a ,  380   b  is constructed similarly to that used for the previously described stroller straps  280   a ,  280   b  except that each end of these stroller straps terminate in either a buckle  382   a ,  382   b  or an opposing bayonet clip  383   a ,  383   b  that may fastened to one another to form a loop as shown in  FIGS. 22 and 23 . The dimensions and operations of the stroller straps  380   a ,  380   b  are the same as above.  
      With reference to both  FIGS. 17 and 18 , the elastic retaining band  294  of the prior embodiment has been replaced with a set of a folded section retainers  361   a ,  363   a  and  361   b ,  363   b . Each retainer includes a length of strap webbing sewn into the upper or lower edge  321 ,  323 , of the bag body that extends outwardly from the bag body  314 . The ends of retainers  361   a ,  361   b  terminate in a buckle  365   a ,  365   b , respectively, while the ends of retainers  363   a ,  363   b  terminate in a complementary bayonet clip  367   a ,  367   b . The retainers are used to capture opposing folded sections  398   a ,  398   b  of the diaper bag body  314  to maintain the diaper bag body in a folded configuration as will be described below.  
      In use, the packing, folding and unfolding steps of this diaper changing accessory organizer  310  are essentially the same as that described above for the organizer embodiment  210  with the following exceptions. As viewed in  FIGS. 17 and 19 , once the diaper changing bag  310  is packed with the accessories (not shown) and the respective closures are fastened, the anchor strip  319   a  of the changing mat  312  may be aligned with the anchor strip  319   b  of the diaper bag body  314  such that the bottom edge  343  of the changing mat coincides with the left intermediate fold well  376   a . This will in turn position the top edge  341  of the changing pad with the left edge  325  of the bag body  314 . The left and right edges  345 ,  347  of the mat extend beyond the underlying bag body as shown in  FIG. 19  and would resemble the placement as in  FIG. 9  of the embodiment above. The changing pad is pressed onto the diaper bag body to mesh the complementary hook and loop fasteners of the anchor strips  319   a ,  319   b  and releasably retain the changing pad to the diaper bag body. The changing pad also covers pockets  344  and  364  of the left storage section  318  and a significant portion of the common central section  316 , respectively, while leaving pockets  354   a - c  of the other portion of the common central section and dual pockets  331 ,  332  of the right storage section  320  exposed. It will be appreciated that the anchor strips  319   a ,  319   b  act as a hinge for the flexible changing pad in that the user can grasp the top or bottom edges  341 ,  343  of the changing pad and flip the respective half over like turning the page of book to expose the underlying pocket  344 ,  364  as mentioned above.  
      With the changing pad  312  secured to the diaper bag body  314 , the pad is folded onto itself as with the pad  212  described above ( FIGS. 10 and 11 ). Referring now to  FIG. 20 , the outer edge  325  of the diaper bag body may be grasped and the left storage section  318  pivoted about the vertical axis projecting through the first pivotal connection  374  and onto the left hand portion of the common central section  316  as with the above described embodiment  210 . The left hand storage section retention flaps  349   a ,  349   b  are aligned with the left half of their corresponding wing anchors  377   a ,  377   b  and pressed thereon to mesh together the respective complementary fasteners ( 351   a ,  351   b  with  377   a ,  377   b ) and releasably retain the left storage section or wing to the spine  373 . The flexible diaper changing mat  312  is folded right along with the folded left storage wing. The diaper pad may be left out if not needed by the user. In such case, the diaper mat attachment and folding steps may be omitted. In either arrangement, a first overlapping region or folded section  398   a  in the form of a bent or folded wing will be configured.  
      In a similar manner, the right hand outer edge  327  of the diaper bag is folded inwardly pivoting about an axis projecting along the length of the rightmost pivotal connection  378  to align the right hand storage section retention flaps  353   a ,  353   b  onto their corresponding spine anchors  377   a ,  377   b  ( FIG. 21 ). The flaps are pressed onto the right half of the corresponding anchors to mesh together the complementary fasteners as well ( 355   a ,  355   b  with  377   a ,  377   b ). Thus, a second overlapping region or folded section  398   b  is configured. As shown in  FIG. 21 , the exterior surface  326  of the left hand and right hand storage sections  318 ,  320 , respectively, and the spine  373  of the common central section  316  are facing the user.  
      Referring now to  FIGS. 21-24 , the user may then fold the common central section  316  along the central pivotal connection  376   a ,  376   b  to either side of the spine  373  bringing the opposing folded sections  398   a  and  398   b  and their respective folded storage sections  318  and  320  together to form a substantially organizer pack as shown in  FIGS. 22-24 . In this configuration, the exterior surface  326  of the left hand storage section and the exterior surface of the right hand storage section are brought together in an abutting relationship to form a relatively thin profile carrying pack. To capture and maintain the opposing overlapping regions  398   a ,  398   b  together, the user may buckle the restraining buckles and clips together ( 365   a  with  367   a  and  365   b  with  367   b ) to releasably secure the overlapping regions  398   a  and  398   b  together as shown in  FIG. 24 . This is the transport configuration and the organizer  310  is ready for travel. The buckle restraints and retention flaps are preferred over the retention band for heavier pocket loads to prevent the diaper bag body from sagging when in a folded configuration and worn on the shoulder.  
      With the bag in a folded condition as in  FIGS. 22-24 , the user may store articles in the exterior security pocket  388 , adjust the strap  384 , and attach the stroller straps  380   a ,  380   b  as described above the organizer embodiment  210 . In addition, the shoulder pad  385  may be slid by the user along the strap  384  for a comfortable adjustment.  
      The diaper changing accessory organizer  310  may be unfolded by unbuckling the external fastener restraints  361   a ,  363   a , and  361   b ,  363   b  from one another, separating or unfolding the overlapping regions  398   a ,  398   b  from one another, and separating the wing restraints  349   a ,  349   b  and  353   a ,  353   b  from their respective spine anchors  377   a ,  377   b . The remainder of the unfolding steps may be accomplished by simply reversing the above-described folding steps to expose the pockets on the interior surface  324  of the bag body and the mat  312 .  
      Regarding both diaper changing accessory organizers  210 ,  310 , to maximize the storage capacity it is preferable to provide pockets across substantially the entire width and height of the diaper bag body  214 ,  314  with fold well or pivotal connections at intermediate locations to facilitate folding of the bag body even when the pockets are full. In addition, the pockets openings are generally configured parallel to the outer edges of the rectangular bag body. In addition, the vertical and inwardly facing openings of each pocket reduce the likelihood of any articles falling out of a pocket during transport even if the closures are left open. The interior facing pockets also reduce the likelihood of theft of important articles during transport. It will further be appreciated that the interior facing pockets and changing pads cooperate to cushion the articles stored in the organizer  210 ,  310  during transportation. While two such exemplary embodiments  210 ,  310  have been described above, other suitable pocket, pocket openings, and fold well configurations may be used. For example, while the diaper changing accessory organizer embodiments illustrated in  FIGS. 6-16  and  17 - 24  are arranged with the changing pad on the left side of the bag body and quick retrieval pockets on the right side of the bag body to accommodate the majority of population, i.e., right-handers, the pockets and pad configurations can easily be reversed for left-handers or other user preferences.  
      The pockets of the respective embodiments  210 ,  310  may be formed in the same manner and with the same materials as for the portable pack  10  and, as with that prior embodiment, it is preferable to use clear plastic sheets in constructing the pockets to form a viewing window such as exemplified by reference numeral  272  ( FIG. 6 ) or  372  ( FIG. 17 ), so that the contents of the pocket may be easily ascertained without having to open the pocket and remove the contents one at a time until the desired article is retrieved. Along these lines, it will be appreciated that the convenient quick release of the restraining band or buckles, quick and easy unfolding and folding process, and transparent pocket viewing windows accommodate a more rapid screening process when passing through airport security.  
      It is also preferable to construct the diaper bag body  214 ,  314  from waterproof materials or at least highly water resistant materials such as nylon, polyester, or other suitable material. As an alternative, the materials or fabrics used to construct the bag body may be treated with a waterproofing substance. This prevents personal articles that may leak from spreading to the remainder of the bag body or diaper changing pad  212 ,  312  when the diaper pad is in contact with the bag. In addition, a wet towel, soiled clothing, or used diaper may be placed in one the sealed pockets without concern of dampening or contaminating the other articles or the changing pad  312 . By providing a waterproof exterior surface  226 ,  326 , the items in the pockets and diaper changing pad are further protected from exterior moisture. In addition, if the contents of the bag body  214 ,  314  are removed or there is no concern if they are compressed, the diaper changing bag  210 ,  310  may be used as a mat underneath the changing pad  212 ,  312  when unrolled and providing an insulating and cushioning surface beneath the changing pad.  
      The changing surfaces  215 ,  315  of the respective changing mats  212 ,  312  are preferably manufactured of a waterproof, wipe clean, non-porous material such as a plastic based material. Alternatively, either changing mat could be constructed of a washable fabric or a combination of wipe clean and fabric surfaces. With either construction, the diaper changing mat is a flexible mat that may be folded into a reduced configuration or unfolded to expand and provide a sufficient changing area surface for changing a baby. Extra changing surface space is preferably provided to prevent the baby from contacting any underlying surface supporting the diaper changing bag when the baby is being changed.  
      While certain fasteners, retainers, or closure devices such as hooks and loop type fasteners, buckles and bayonet clips, zippers, and elastic restraining bands have been described herein, it will be appreciated that snaps, buttons, magnets, releasable adhesives or other suitable complementary fasteners may be used in place of or in combination with those fasteners. Also where a sewn article is indicated, adhesion, welding, and other suitable joining techniques including those mentioned herein may be used. Also, the dimensions discussed herein are not meant to be limiting in any manner or other suitable dimensions will occur to one of ordinary skill in the art.  
      While the present invention has been described herein in terms of a number of preferred embodiments, it will be appreciated that various changes, uses, and improvements may also be made to the invention without departing from the scope and spirit thereof
