Additionally, unless specifically identified otherwise, all embodiments described herein should be considered exemplary. 
       FIG.  1    shows a front, top perspective view of an apparatus  100  for carrying items, the apparatus  100  being a piece of carry-on luggage  100  for illustration. The apparatus  100  includes the top panel  102 , the front panel  104 , and the right side panel  106  of the apparatus  100 , all of which are shown. The apparatus  100  is shown standing upright and balanced with the bottom of the apparatus  100  on a flat level surface with the frame member (described below and not shown in this view) expanded away from the back to increase an interior volume of the apparatus  100  while the apparatus  100  is being used for carrying the items. The apparatus  100  may include a top handle  108 ; a telescoping handle  110  (i.e., fully retracted into the back); a first closure device  112 , such as a zipper, for a compartment in the top for storage of items (which compartment is explained further below); and a second closure device  114 , such as a zipper. 
       FIG.  2    is a back, top perspective view of the apparatus  100  of  FIG.  1    showing the top panel  102 , back panel  202 , and left side panel  204 .  FIG.  2    also shows the top handle  108 , the telescoping handle  110  (i.e., fully retracted into the back), the first closure device  112  for the compartment in the top for storage of items, the second closure device  114 , and two wheels  206 . The back panel  202  may include a pair of slides  208 . In this view, as in  FIG.  1   , the apparatus  100  is standing upright and balanced on the bottom of the apparatus  100  on the two wheels  206  and on the frame member (not shown in this view) on the flat level surface with the frame member expanded away from the back to increase the interior volume of the apparatus  100  while the apparatus  100  is being used. 
       FIG.  3    is another back, top perspective view of the apparatus  100  with the frame member (not shown in  FIG.  3   ) expanded away from the back to increase the interior volume of the apparatus  100  while the apparatus is being used. The telescoping handle  110  is shown fully extended. 
       FIG.  4    is a bottom, front perspective view of the apparatus  100  also with the telescoping handle  110  fully extended and a foot portion  502  of a frame member  500 . The frame member  500 , explained further below, is expanded away from the back to increase the volume of the apparatus  100  while the apparatus  100  is being used. The foot portion  502  of the frame member  500  serves, in this example, as a bottom handle and as a foot or counterbalance for the apparatus  100  such that when balanced on the wheels  206 , the front weight of the apparatus is borne by the foot portion  502 . The foot portion  502  may be referred to as a descending foot portion  502  as it descends below the bottom panel  503  and/or below the remaining portion of the frame member  500  to form a foot or counterbalance. The foot portion  502  of the frame member  500  is shown having a trapezoidal shape and contains four “bottom bends”  501 . The bends  501  are configured to allow the frame member  500  to extend below the bottom panel  503  to provide a weight bearing foot  504 . Generally, the top, front, and side panels are fabric in this exemplary embodiment. The bottom panel  503 , however, may be a plastic curved substantially rigid bottom member, such as a pan or the like, that forms part of the bottom at the intersection of the back and the bottom, and the two wheels. Also visible in this view are loops of webbing that serve as exterior connection points for attachment of the shoulder straps (shoulder straps not shown in this view). 
       FIG.  5    is another bottom, front perspective of the apparatus  100  of  FIGS.  1  to  4    showing the bottom panel  503 , the front panel  104 , and the left side panel  204  with the apparatus  100  placed on the rails  208  (see  FIG.  2   ), its back with the frame member  500  expanded away from the back to increase the interior volume of the apparatus  100 .  FIG.  5    shows the second closure device  114  open (or unzippered in this case), the front panel  104  is pulled open, and the items removed. The apparatus  100  includes the foot portion  502  of the frame member  500 . In this exemplary embodiment, the bottom panel  503  is formed from a pan comprising the curved substantially rigid bottom member that forms part of the bottom at the intersection of the back and the bottom, the two wheels  206 , and the loops of webbing for attachment of the shoulder straps (shoulder straps not shown in this view). The back panel  202  provides for the telescoping handle  110 . A compartment  505  is on the inside of the front for separate storage of some of the items. The compartment  505  is formed by a space between two plies of fabric on the front panel  104 . The compartment is accessed by a third closure device  506 , such as the zipper shown. 
       FIG.  6    is a view from the top of the bottom panel  503  on the inside of part of the apparatus  100  of  FIGS.  1  to  5   . The frame member  500  is expanded away from the back to increase the interior volume of the apparatus  100 . As in  FIG.  5   , the second closure device  114  is open (or unzippered in this example), and the front has been pulled open. The bottom panel  503  includes a first fabric cover  600  that covers a substantially rigid folding bottom board  602  (see  FIG.  7   ) that is attached to a remainder of the bottom panel  503  with a fabric hinge  604 . A first releasable hook and loop fastener  606  (partially visible in this view behind the folding bottom board) also attaches the folding bottom board to the remainder of the bottom. The front edge of the folding bottom board  602 , when unfolded, is proximal the intersection of the front panel  104  and the bottom panel  503  as shown in  FIG.  6   . The bottom panel  503  also includes a second fabric cover  608  that forms part of the bottom at the intersection of the back and the bottom. The second cover  608  has a front edge  610  releasably attached at the front with a second releasable hook and loop fastener  612 . The apparatus  100  includes straps  614 , which may include a plurality of straps releasably coupled with a buckle  616  as shown, for securing the items within the apparatus  100  (i.e., a bottom one of two straps also visible in  FIG.  5   ). 
       FIG.  7    is a view, similar to  FIG.  6   , of the same part of the same apparatus  100 . The first releasable hook and loop fastener  606  has been released, and the folding bottom board  602  has been folded, lifted, or pivoted about the fabric hinge  604 . When folded, the front edge of the folding bottom board  602  is distal (or removed from) the intersection of the front panel  104  and the bottom panel  503  as shown in  FIG.  7   . Pivoting the substantially rigid folding bottom board  602  from its position in  FIG.  6    allows the bottom panel  503  to collapse, which allows the front panel  104  to move toward the back panel  202  to reduce volume of the apparatus  100  (e.g., for shipping, storage, or both). 
       FIG.  8    is another view similar to the views of  FIGS.  6  and  7   , where like parts will not be reidentified. As shown in  FIG.  8   , the apparatus  100  has been collapsed, at least in part, and a cam strap  800 , which is shown near the bottom panel  202 , is holding the frame member  500  (not visible in  FIG.  8   ) collapsed toward the back panel  202  at the bottom, which reduces the interior volume of the apparatus  100 , which may be useful for shipping or storage. As in  FIG.  7   , the first releasable hook and loop fastener  606  has been released to allow the substantially rigid folding bottom board  602  to be folded, lifted, or pivoted. The front edge of the folding bottom board  602  is still distal the intersection of the front panel  104  and the bottom panel  503 . While shown as a cam strap  800 , any suitable compression device may be used, such as an elastic cord or the like. 
       FIG.  9    is a perspective view of the left side of the apparatus  100  collapsed. While not required, a cam strap  800  may be used to hold the frame member  500  collapsed toward the back at the bottom and the front collapsed toward the back to reduce interior volume of the apparatus  100 , such as may be useful for shipping or storage. Compression members other than a cam strap  800  are possible. In  FIG.  9   , the second closure device  114  is closed. The left side panel  204  and the front panel  104  are visible, and the top panel  102  and top handle  108  are collapsed in this view. The frame member  500 , which will be explained below, may be biased to the expanded state, away from the back, when compressive pressure is removed. 
       FIG.  10    is a view of the right side of the apparatus  100  expanded, without the cam strap  800 .  FIG.  10    can be compared with  FIG.  9    to see an example of the relative ability to collapse the apparatus  100 . Of course, the actual difference in size depends on a number of design factors. (i.e.,  FIG.  9    compared to  FIG.  10   ) for shipping or storage. Some parts as described above are shown in  FIG.  10    for orientation. The volume may be reduced by almost any ratio. In certain embodiments, the folding bottom board  602  may allow a volumetric reduction to 50% or the overall interior volume in the normal course. Other designs may reduce the volume to between about 15% to 25% or between about 75% and 80%. In still some other embodiments, the folding bottom board  602  may have multiple folds to allow different reductions between about 15% and 80%. 
       FIG.  11    is a front view of the apparatus  100  showing the top panel  102  and front panel  104  with the shoulder straps  802  attached to exterior connection points  804 , which may be fasteners or loops of webbing as shown. Other features as described above are shown in  FIG.  11    for orientation. 
       FIG.  12    is another view of the apparatus  100  with the shoulder straps  802  deployed. 
       FIGS.  13  and  14    are views of the apparatus  100 . Apparatus  100  may include a fourth closure device  806 , such as the zipper shown. The fourth closure device  806  allows access to a compartment in the left side panel  204 . The compartment may be approximately the length of the apparatus  100 , which may be suitable for storage of long items such as an umbrella. 
       FIG.  15    is a front, elevation view of an example of the frame member  500  of the apparatus  100 . The frame member  500  includes a left (or first) longitudinal member  702 , a right (or second) longitudinal member  704 , and a transverse base member  706 . The traverse base member  706  has a left base portion  706 ( 1 ) and a right base portion  706 ( 2 ). A left bend  708 ( 1 ) transitions between the left longitudinal member  702  and the left base portion  706 ( 1 ), which is shown as a 90-degree bend but could be between about 75 and 105 degrees. A right bend  708 ( 2 ) transitions between the right longitudinal member  702  and the right base portion  706 ( 2 ), which is shown as a 90-degree bend but could be between about 75 and 105 degrees. The foot portion  502  is between the left base portion  706 ( 1 ) and the right base portion  706 ( 2 ), which foot portion  502  is explained above with reference to  FIGS.  1 - 4   . The weight bearing foot  504  may have a plastic part  710 , which may be a snap-on part or an overmolding. Also shown is a plastic component that the frame member extends through between the bottom bends at the (e.g., bottom) handle or foot. The frame member of the apparatus and carry-on luggage of  FIGS.  1  to  14    is similar to the frame member shown in  FIG.  15    except without the plastic component. 
       FIG.  16    is a side view of the frame member  500  of  FIG.  15   .  FIG.  16    illustrates, among other things, that the left longitudinal member  702  (and the right longitudinal member  704  although not shown in  FIG.  16   ) has a radius of curvature R of an arc from the transverse base member  706 . When the apparatus is uncollapsed, the left longitudinal member  702  extends from the front, left edge of the bottom panel  503  to the back, left corner, proximal the side panel  204  and back panel  202 . The right longitudinal member  704  has a similar extension but converges to the right side panel  106 . The radius of curvature R along the length of the left and right longitudinal members  702 ,  704  may be variable and have a steeper arc over portions of the members. In particular, the radius of curvature may be smaller the further along a length of the left and right longitudinal members  702 ,  704  where the radius of curvature decreases from the bottom panel  503  to the top panel  102 . 
       FIG.  17    is an isometric view of the frame member  500  of  FIGS.  15  and  16   . The frame member  500  may reside between the inner and outer plies of the left side and right side panels  204 ,  106  ( FIGS.  1  and  2   ). Similarly, the transverse base member  708  may be contained, at least partially, in a sleeve or seam associated with the bottom panel  503  and the front panel  104  ( FIGS.  1  and  4   ) The left and right longitudinal members  702 ,  704  may terminate at a terminal end  712  that has a bend  714 , which inhibits wear on the fabric. In other embodiments, the terminal end  712  may be capped. 
       FIGS.  1 - 17    and this patent application describe, among other things, examples of certain embodiments of collapsible (having collapsed and uncollapsed configurations) apparatuses, such as, the apparatus  100  described above, which is an example of carry-on luggage. Other embodiments may differ from the particular examples described herein. Some apparatuses may be backpacks, other shipping and storage containers, child carriers, duffle bags, suitcases, or the like. In some embodiments, for example, the volume is reduced by about half. This can reduce the cost of shipping, storage, or both. The frame member  500  may extend, for example: across the left side panel  204 , along the bottom panel  503  (or the front panel  104 ), from the left side panel  204  to the right side panel  106 , across the right side panel  106 , from the back panel  202  to the front panel  104  (in various embodiments at the left side panel  204 , at the right side panel  106 , or at both), or a combination thereof. The bottom panel  503  includes a folding bottom board  602 , in some embodiments, for example, attached in certain embodiments with a fabric hinge  604 . The apparatus  100  may balance, for example, on two wheels  206  and the foot portion  502  of the frame member  500 . The frame member may be: steel (e.g., coated) or stainless steel, as examples. Further, the frame member  500  may be pieces coupled together, solid, monolithic, or a combination thereof. The frame member  500  may have parts that have a round cross section. The foot portion  502  of the frame member  500  may be used as a handle as well as a foot. Shoulder straps are stored in a front (e.g., zippered) compartment in some embodiments, for example, to carry the apparatus as a backpack. 
     Referring back to  FIGS.  1 - 17   , the apparatus  100  includes a back panel  202 , a front panel  104 , a bottom panel  503 , a right side panel  106 , a left side panel  204 , and a frame member  500 . The frame member  500  may be contained and move between the outer and inner plies of the panels. Still further, in various embodiments, the frame member  500  collapses, for example, toward the back panel  202 , for instance, to allow the front panel  104  to collapse (e.g., toward the back panel  202 ), for example, to reduce volume of the apparatus  100 , for instance, for shipping, storage, or both. Even further, in a number of embodiments, the frame member  500  expands away from the back panel  202 , by the earlier described arc with a radius of curvature R, for example, to increase the interior volume of the apparatus  100  when the apparatus  100  is being used. As can be appreciated, increasing or decreasing the interior volume of the apparatus  100  is a relative term. As used in this application, increasing the interior volume means to increase the interior volume from the apparatus  100  in the collapsed state and decreasing the interior volume means to decrease the interior volume from the apparatus  100  in the uncollapsed state. The frame member  500  has a left longitudinal member  702  that extends across the left side panel  204 , a transverse base member  706  that extends along the bottom panel  503 , and a right longitudinal member  704  that extends across the right side panel  106 , or a combination thereof, as examples. 
     As shown in  FIGS.  6 - 8   , the apparatus  100  includes a substantially rigid folding bottom board  602  that is attached to the bottom panel  503  with a fabric hinge  604 . As used herein, “substantially rigid” means rigid enough to maintain its shape within ten percent of an overall dimension of the component when subjected to typical forces experienced by the component. Moreover, as used herein, plastic commonly used for the construction of luggage is considered to be substantially rigid. Fabric, on the other hand, without more, is not “substantially rigid” as used herein. The folding bottom board  602  has a first position, as shown in  FIG.  6   , when the apparatus  100  is in the uncollapsed configuration. The folding bottom board  602 , being substantially rigid, holds the transverse base member  706  toward the front edge  610  of the folding bottom board. As shown in  FIGS.  7  and  8   , the folding bottom board  602  may be folded, at about the halfway point between the uncollapsed back panel  202  and front panel  104 . When folded, the transverse base member  706  may be moved toward the back panel  202 , which in this example reduces the interior volume by about half as the frame member  500  is moved and compressed. The compression of the frame member  500  may provide a biasing force tending to move the transverse base member  706  away from the back panel  202 , which may require the use of a cam strap  800  as described above. 
     In a number of embodiments, the apparatus (e.g., further) includes a top panel  102 . The top panel  102  extends from the back panel  202  to the front panel  104 , and the top panel  102  extends from the right side panel  106  to the left side panel  204 . The top panel  102  generally is made from fabric, which may be single ply, two-ply, or multiple plies. The top panel  102  in certain aspects may consist essentially of fabric but include some other elements such as rigid plastics or the like, as examples. Forming the top panel  102  from fabric (or essentially from fabric) allows the top panel  102  to collapse, for example, to allow the front panel  102  to move (e.g., toward the back panel  202 ), for instance, to reduce the interior volume of the apparatus  100 . 
     The frame member  500  may be made of, include, or consist essentially of, stainless steel. Still further, in certain embodiments, the frame member  500  is made of, includes, or consists essentially of, coated steel, as another example. Even further, in various embodiments, the frame member  500  is made of, includes, or consists essentially of, wire, for example, spring wire, for instance containing bends (e.g., as described herein). In other embodiments, the frame member  500  is, includes, or consists essentially of: plastic (e.g., molded polypropylene, 3-D printed material, or tent pole material), fiber-reinforced plastic, fiberglass, carbon fiber, or carbon-fiber-reinforced plastic, as examples. 
     In various embodiments, the frame member  500  includes one or more (e.g., multiple) bends. For example, in a number of embodiments, the frame member  500  includes a right side bend  708 ( 2 ), for example, at, or substantially at, an intersection of the right longitudinal member  704  side and the right base  706 ( 2 ). In this context, “substantially at” means within ten percent of an overall dimension of the apparatus in the same direction. In particular embodiments, for example, the right side bend  708 ( 2 ) is substantially a 90-degree bend. As used herein, when referring to angles or planes, “substantially” means to within 10 degrees. Further, in some embodiments, the frame member  500  includes a left side bend  708 ( 1 ). For example, in certain embodiments, the left side bend  708 ( 1 ) is at, or substantially at, an intersection of the left longitudinal member  702  and the left base  706 ( 1 ). Still further, in particular embodiments, the left side bend  708 ( 1 ) is substantially a 90-degree bend. Even further, in various embodiments, the right side bend and the left side bend are in a substantially common plane, have substantially equal angles of bend, or both. 
     Further, in some embodiments, the frame member includes a foot portion  502 , for example, suitable to balance or counterbalance and support the apparatus  100 . In a number of embodiments, for example, the foot portion  502  is formed in the frame member  500 , specifically in the transverse base  706 , for example. 
     In various embodiments, the frame member  500 , for example, includes a radius of curvature R forming a left, right arc, for instance, in the left, right longitudinal member  702 ,  704 . For example, in particular embodiments, the right arc has an angle of bend between 30 and 80 degrees. The radius of curvature may vary over the length of the left, right longitudinal members  702 ,  704 . The left and right arcs are substantially coplanar with the left and right side panels  204 ,  106 . Even further, in various embodiments, the left and right side panels  204 ,  106  include fabric, for example, two layers (or plies) of fabric. In some embodiments, the left, right longitudinal members  702 ,  704  of the frame member  500  are located between the two plies of fabric or within a right sleeve in the left or right side panels  204 ,  106 . In some embodiments, the sleeves are formed by sewing the fabric. The sleeves are curved to match the arcs. 
     In some embodiments, the apparatus  100  includes (e.g., two) shoulder straps  802 , for example, for carrying the apparatus  100  on a user&#39;s back. Further, in particular embodiments, the apparatus  100  or the front panel  104  of the apparatus  100  includes a shoulder strap compartment  808 , possibly secured by first closure device  112 , in which the shoulder straps are stored when not in use, and possibly stitched or coupled to an inside of the shoulder strap compartment  808 . In a number of embodiments, the shoulder strap compartment  808  can also be used to carry items (i.e., other items besides the shoulder straps  802 ), for example, items like papers or a book to read while traveling. The shoulder straps  802 , in a number of embodiments, may be connected to connection point  804 , which may be a loop, a web of material, a snap, a buckle and tab, or other equally well known types of connectors. In some embodiments, the two exterior connection points  804  are located at or substantially at: an intersection of the front panel  104  and the bottom panel  503 ; an intersection of the front panel  104  and the right side panel  106 , and an intersection of the front panel  104  and the left side panel  204 ; or some combination thereof. 
     In various embodiments, the apparatus or the bottom includes a (e.g., substantially rigid) folding bottom board  602  as explained above. The folding bottom board  602  is attached with a fabric hinge  604  in this exemplary embodiment. Other hinge connections are possible such as, for example, a piano hinge or the like. The fabric hinge  604 , or other hinge, is a means for folding the folding bottom board  602 . Generally, a fabric hinge means that bending of the fabric provides the rotation or pivoting of the hinge rather than rotation around a pin or axle. Still further, in a number of embodiments, the (e.g., substantially rigid) folding bottom board stiffens the bottom panel when the apparatus is being used. The (e.g., substantially rigid) folding bottom board  602  stiffens the bottom panel  503 , in part, when the frame member  500  is expanded (e.g., away from the back panel  202 ). Folding the folding bottom board  602  allows the bottom panel  503  to collapse, at least in part, to allow the front panel  104  to move toward the back panel  503 , which reduces the interior volume of the apparatus  100 . The apparatus  100  includes the first releasable hook &amp; loop fastener  606  that attaches the folding bottom board  602  to (e.g., a remainder of) the bottom panel  503  in an unfolded condition and is released (or the hook ply is separated from the loop ply) to allow the folding bottom board  602  to be folded away from the bottom panel  503 , which allows the front panel  104  to collapse toward the back panel  202 . The first releasable hook and loop fastener  606  is, includes, or consists essentially of, a hook and loop fastener (e.g., Velcro®) for example. Other embodiments, however, may use a different type of releasable fastener, such as one or more snaps, buttons, zippers, or a combination of all the above or other known releasable fasteners. 
     In a number of embodiments, the frame member  500  is in compression and pushes the front panel  104  away from the back panel  202 . In other words, the frame member  500  may act as a spring. Still further, in various embodiments, the apparatus is a piece of luggage, for example, a piece of carry-on luggage.
