Abstract

A Foldable Insulated Container may be made of a three piece assembly of a base, a front wall and a rear wall. The base may include a reinforcement such as may tend to urge the base to retain a substantially planar orientation, and which may aid in folding the insulated bag. The insulated bag may include a trailing member. The trailing member may be attached to the base.
The trailing member may include wheels. The trailing member, or apparatus, may include a retractable wheeled undercarriage.

Description

FOLDABLE INSULATED BAG WITH TRAILING MEMBER
Field of Invention This invention relates to the field of foldable insulated containers.
Background of the Invention Collapsible insulated containers have been known for some years. They are typically used as containers for carrying cold drinks, and other cool refreshments, but can also be used keep foods or beverages warm or hot.
Certain sizes and shapes of coolers are better for some purposes than others.
Some collapsible coolers can be folded to a collapsed position, but the folding process may tend to require relatively strong hands, since the insulated panels may be of fair thickness, and may have a resilience that tends to resist folding. These containers tend to unfold easily, but tend to be rather more difficult to fold back into the collapsed or storage position. In the folded position, the front and rear walls remain in generally parallel planar orientation while the bottom panel is folded up in half, and the side panels are folded inward as shown in my issued US Patent Des.
382,771. This kind of cooler is secured in the folded position (a) by a hook-and-eye fabric strip securement between the overfolded lip of the lid portion of the cooler and the front face of the cooler and (b) by side fastening straps that retain the bottom portions of the front panel relative to the back panel, typically by wrapping at least partially around the back panel and being secured thereto with hook-and-eye strips. Coolers of this nature tend to be generally cubic in shape with rectangular sides forming, typically, a six sided box shaped structure when unfolded.
A cooler of this type may also tend to require more manufacturing steps than a more bag-like cooler, and may therefore be more costly and time consuming to produce.
Rolling up a collapsible cooler, in the manner in which a sleeping bag is sometimes rolled up, may tend not to be particularly satisfactory in all circumstances.
Users may tend to roll up the insulated material too tightly, either damaging the material, or tending to give it a permanent set. This tight rolling approach may also tend to favour persons with relatively strong hands.
It may be that a different kind of cooler is desired that may be somewhat more convenient for rapid use, that may be more quickly and easily folded, or that may provide greater ease of manufacture, that may tend to pack efficiently for shipment, or that may present a relatively easily displayed product.
It may also be that it would be helpful to have a cooler that folds in a continuous S direction, or that folds back and forth, on a folding panel basis rather than in a continuous tight roll like a sleeping bag. Optionally, it may be helpful to have members that facilitate towing of the bag.

Detailed Description of an Embodiment of the Present Invention The description that follows, and the embodiments described therein, are provided by way of illustration of an example. or examples, of particular embodiments of the principles of the present invention. These examples are provided for the purposes of explanation, and not of limitation, of those principles and of the invention. In the description, like parts are marked throughout the specification and the drawings with the same respective reference numerals. The drawings are not necessarily to scale and in some instances proportions may have been exaggerated in order more clearly to depict certain features of the invention.
For the purposes of this description, the largest panels of the bags herein described are arbitrarily designated as the front and rear sides, faces, or portions of the bag. Similarly, the closure member, or opening of the bag is arbitrarily designated as being at the top, and the base panel is designated as being at the bottom. It should also be understood that, within the normal range of temperatures to which human food and human touch is accustomed, although the term cooler, or cooler container, or cooler bag, may be used, such insulated structures may generally also be used to keep food, beverages, or other objects either warm or hot as well as cool, cold, or frozen.
As seen in the Figures, an example of a portable, collapsible soft sided, insulated wall structure is identified as a foldable cooler tote bag 20. This structure can be referred to as an insulated bag, an insulated container, a cooler, or such like. The basic structure of bag 20 includes a first side panel, or wall, or sidewall, arbitrarily designated front panel 22, a second side panel, or wall, or sidewall, designated arbitrarily as rear panel 24, and a third panel or wall _7_ identified as a bottom, or base panel 26. As described more fully below, these panels are joined together to form a pouch, or bag, having an enclosed internal space 25 surrounded by insulated walls. The enclosed volume of internal space 25 varies with the condition of the bag. That is, while the bag is in a folded (that is, collapsed) condition or position, or is lying flat, the internal volume is negligibly small, if not zero. However, when bag 20 is in an unfolded condition, or expanded position, it may tend to take on a shape to accommodate objects placed within the internal space, and it may assume a suitably capacious internal volume.
When bag 20 is in use, access to the internal volume, namely internal space 25 thereof, is governed by a closure member 28. In the illustrated example, closure member 28 may be a linear tracked closure device in the nature of a zipper assembly 30 mounted between the upper margins of the side wall panels, namely front and rear panels 22 and 24. Other kinds of closures could be used such as a Velcro (t.m.) hook-and-eye fabric closure, a series of spaced apart snaps, a continuous mating plastic tongue and groove or other device. A relatively robust zipper assembly is preferred, as it may tend to provide a simple, quick, and relatively strong closure.
While bag 20 can be made water-tight by other means, it is preferred to provide a liner 32 that can be either sewn in place, or it may be removable, or it may be wholly or partially invertible. A liner that is at least partially invertible, or removable, is preferred, since this may facilitate washing.
When the bag is not in use, it may tend to be readily foldable. First, the bag is collapsed by being laid flat, and then folding front sidewall panel 22 near its bottom margin, such that base panel 26 may lie in a more or less flat orientation relative to the rear sidewall panel, 24, as seen in Figures 6a and 6b. In this, collapsed, generally flattened, position, the upward edge 36 of base panel 26 (namely the edge that is folded toward front sidewall panel 22 and hence toward what would normally be the upper parts of bag 20 generally) acts as a former, or form, for bending the body of bag 20 to define a first fold by rotating the folded part of the bag in the direction of arrow 'A' (counter-clockwise in the Figures, but arbitrary since it would be clockwise if viewed from the other direction, and bag 20 can be made with either a left handed or right handed fold). This permits one portion of bag 20 to fold over on another portion, in the manner of folding a page over on itself.
When page-folded in the direction of arrow 'A', bag 20 will arrive at the folded position shown in Figures 3a - 3g, in which position it is held by a securement member, or retainer, identified as 34, which may take the form of a pair of mating securement strips such as hook-_g_ and-eye velcro (t.m.) strips 38 and 40 mounted, respectively, to the upper body portion of front side panel 22 adjacent the upper margin thereof, and to the distal margin region of base panel 26 that is distant from the forming edge of base panel 26, such that when base panel 26 is overfolded in the direction of arrow 'A' strips 38 and 40 are brought into mating contact in a single relatively uncomplicated, and possibly quite swift motion. The result is a soft sided insulated container that has been collapsed, and then panel-folded over on itself (i.e., not scrunched into a tight roll) to a flat folded position, or flat folded condition, such as may be suitable, for example, for stacking, transport, display or storage. Display and storage is facilitated by a suspension member 42, in the nature of a hang loop 44, mounted generally centrally along the upper margin of front panel 22. To the extent that loop 44 is mounted higher than the center of gravity of bag 20 more generally, bag 20 will tend to hang with the upper margin of front panel 22 in a generally horizontal orientation. An alternate hang loop location is shown in Figure 3h, in which hang loop 44 is located at an end edge such that, when displayed for sale, bag 20 may tend to hang in a vertical, or substantially vertical orientation, namely with the long dimension (as folded) running up and down, i.e., more or less vertically.
Unfolding may tend to be a similarly uncomplicated and convenient procedure:
the retainers are released, the bag is unfolded and it is ready to accommodate objects that need to stay cool or warm. When unfolded, lifting members in the nature of handles, or straps 46, 48 that extend from the upper regions of the sidewall panels, namely panels 22 and 24, can be grasped to lift bag 20, and may, as illustrated in Figure 1, be found suitable for carrying over a person's shoulder. Alternatively, or additionally, as illustrated in Figure 2, bag 20 is provided with auxiliary securement devices 50, 52, such as may be in the nature of velcro straps, to engage the felt-like or fibrous mat interior of an automobile, especially an automobile trunk, or boot, or cargo carrying area of a station wagon, van, or sports or utility vehicle. Securement devices 50, 52 may tend to be used to discourage a loaded bag 20 from tipping over when travelling, such as when bringing cold items home from the grocery store, or such as when transporting refreshments to a campsite, picnic site, playing field, or arena.
Considering the construction of bag 20 in greater detail, reference is made to the developed views of panels 22, 24 and 26 provided in Figure 8. In the developed views shown in the example of Figure 8, the side panels, namely insulated front and rear panels 22 and 24, are of the same size and shape, and are generally rectangular. They have a breadth dimension indicated as 'X' measured along either the upper or lower marginal edges 54, 56, and a height dimension indicated as 'Y', measured perpendicular to dimension 'X', along the side edges 58, 60. By inspection, L1 = 'X' = bl + 2a1.

Insulated base panel 26 is also generally rectangular, having a long dimension measured along long edges 62, 64 and indicated generally as 'b' and a short dimension measured along the short end edges 66, 68, indicated generally as 'w'. In this embodiment, the half width of the panel is identified as 'al', and is equal to half of 'w' . The ratio of the half width 'a' to the length 'b' may tend to be in the range of less than about 1 : 2 and greater than about 1 : 16, or within the narrower range of less than about 2 : 5 and greater than about 1 : 8, or within the preferable range of less than about 1 : 3 and greater than about 1 : 6. In one particular example the ratio may be about 3 '/4 : 11 '/Z, in another particular example the ratio may be about 3 '/4 : 15 '/Z, and in a third particular example the ratio may be about 3 1/4 : 17 '/4.
The width of base panel 26 may also be related to the overall height of bag 20 when unfolded. That is, retainer strip 40 on the off side of base panel 26 may mate with strip 38 on front panel 22 of bag 20 at a region close to the upper edge 70 of bag 20 generally, to yield a neatly folded bag for efficient packing, shipping and display. To that end, with allowance for a bend radius, it is preferred that the height of bag 20 be within +/- 20 %, and more preferably within +/-10 %, of an integer multiple of the width of base panel 26. It is also preferred that bag be a double or triple folded bag. While bags with a greater number of folds are possible, the benefits of ease of manufacture, ease of folding, and ease of use may not necessarily tend to be 20 as marked for a larger number of folds.
The upper edge, i.e., upper marginal edge 54, of each of the side panels 22 and 24 is longer than the long dimension 'b' of the bottom, or base panel 26, such that when the closure member is secured, bag 20 may tend to have an upwardly broadening profile when viewed from the side and an upwardly narrowing profile when viewed from the end. In the embodiment of Figure 8, the periphery of base panel 26 is equal to 2(2a1 + b). Each of the side wall panels, namely front and rear panels 22 and 24, has a lower, or bottom edge, 56 noted above. Each of these bottom edges 56 extends about one half of the periphery of base panel 26, having a central portion of length 'b' and two opposite end portions, each of length 'al', or thereabout. In this instance when bag 20 is collapsed, and bottom panel 26 is laid flat, a triangular end fold will be created, made up of the triangular folds 72 of the bottom corners of the side wall panels, those triangular portions being indicated as triangular regions 74 in Figure 8, and being bounded by fold lines 76, 78.
When assembled, front and rear panels 22, 24 are sewn together along their upwardly extending edges 58, 60, the central portions of their bottom edges 56 are sewn to the long sides, or edges 62, 64 of base panel 26, and the end portions are sewn to the half width portions of end edges 66, 68 of base panel 26. The closure member 28 has the form of zipper assembly 30 as noted above. Zipper assembly 30 has a first side region 84, a second side region 86, and a zipper 88. Side region 84 has an outboard, or distal edge seamed into front panel 22, and an inboard edge, or margin, to which one set of teeth of zipper 88 is mounted. Side region 86 has an outboard, or distal edge that is seamed into rear panel 24, and an inboard edge along which the other set of teeth of zipper 88 is mounted. In the usual manner, motion of zipper car 90 along the track defined by the zipper teeth controls the opening and closing of the zipper assembly, and hence controls access to the enclosed space 25 of bag 20 more generally, thereby permitting objects to be introduced into, or to be drawn out of, bag 20. Side regions 84 and 86 each have an upper, load bearing web member 92, 94 and an inner wall member 96, 98. In one embodiment of the invention, inner wall members 96, 98 may be reflective, or have a reflective inwardly facing (i.e., inward relative to the enclosed space 25 of bag 20 so that the reflective surface is oriented toward objects contained in bag 20) surface, and may preferably be made of "
thermoflect" (t.m.) material. In another embodiment, inner wall members 96, 98 is a white, water proof nylon sheet. The seaming of the side region of zipper assembly 30 occurs at a height downset from the very edge of the side wall panels by a distance 8~ roughly equal to the half width SZ of zipper assembly 30 such that when bag 20 is folded, side regions 84 and 86 may tend to fold next to those margins, rather than to protrude excessively.
The overall width of the web-like region, or panel, formed by zipper assembly 30 is less than, if not significantly less than, the width of panel 26, such that the through thickness of bag 20 at the elevation of closure member 28 is small, if not very small, relative to the length of closure member 28, and relative to the length of upper marginal edge 54. It is preferred that the overall width of the closure member be less than 60% of the width of the base, and, in a particular example, is about half the width. As such, the ratio of through thickness to bag length may be about a2/ (2az + b). This value may typically lie in the range of 1 : 5 to 1 : 8 and more narrowly in the range of 1 : 6 to 1 : 7 %Z. The closure member is mounted between the upper margins of the side wall panels, namely panels 22 and 24, and, when open, permits at least central portions of those margins to be moved closer together or further apart as may be desired to give access to the enclosed chamber.
The sidewall construction is as shown in Figure 5. Each of sidewall panels 22, 24 has a relatively wear resistant outer membrane or sheet, or web 80, that may be made of a sheet or woven webbing fabric, such as woven nylon, canvas, or other suitable cloth.
Each of sidewall panels 22, 24 also has an inner sidewall membrane, or sheet, or web 82, that may function as a water proof lining, and may be made of a sheet of extruded plastic of the types of polymers that include vinyl (t.m.) or nylon (t.m.), or sheets of monolithic extruded vinyl (t.m.) or nylon (t.m.) sewn together.
An insulating layer 84 is trapped between the inner and outer webs 82 and 80.
Insulating layer 84 may preferably be a closed cell polyurethane foam, but could be an open cell insulating foam, or other type of insulating layer, or it may include more than one insulating layer.
As above, in one embodiment the inner sidewall web member may either be made of a reflective material, such as thermoflect (t.m.) sheeting, or may have a reflective surface oriented to face toward objects contained within bag 20. Alternatively, inner web 82 member may be made of a water proof extruded nylon or vinyl sheet, or seamed sheets, to discourage leakage of liquids from bag 20.
Optionally, water-proof liner 32 may be included, in addition to the internal sidewall web sheet, namely, web 82. Where the inner sidewall surface is reflective, the liner may preferably be translucent, or clear, to permit the reflective surface of the inner wall to be seen. Although the liner can be rigidly sewn in place to prevent the liner from being inverted, it is preferable for the liner to be either removable, or to be sewn in at its upper peripheral edges, thus permitting at least partial inversion of the liner as shown in Figure 7a, and hence to facilitate washing. The optional liner 32 may be made from a single polymer sheet, have a first side region 84 and a second side region 86. The side regions are heat welded along their side margins to form a pouch, or pocket, commensurate with the general site and shape of the inside of bag 20, and have their upper margins seamed into the side-walls of bag 20 at the juncture with the side regions of zipper assembly 30. Bag 20 will then tend to be water-proof to a height corresponding to the height of closure member 28. A soft sided insulated wall assembly for use as a cooler, such as bag 20, may be generally leak resistant and may be water-proof.
The cross-sectional structure of base panel 26 is generally similar to the cross-sectional structure of the sidewall panels, having an inner wall skin, or panel or web 114 that is of consistent construction to the inner wall sheet or web 82, and an outer wall skin, or web 116 that is of consistent construction to outer web 80. It may be noted that the outer web 80 may not be the same colour as outer web 116, and may not be of the same weave or fabric.
It may have a heavier, more wear resistant fabric, or coarser, more wear resistant weave, since base panel 26 may tend to be placed in contact with the ground, or other underlying surface whether a paved roadway, concrete, rocks, earth, flooring, or some other support surface against which it may be expected to be slid, or to rub, in the course of use.

Base panel 26 may also have an insulated layer, 118, captured between webs 114 and 116, the insulated layer being made of an insulated foam or other suitable heat transfer resistive medium as described above. In addition, base panel 26 has a stiffened form member 120 that may be in the nature of a rectangular, hard plastic sheet 100 of modest thickness located between insulating layer 118 and outer web 116. Sheet 100, in plan view, has dimensions that are the same as. or roughly the same as, dimensions 'b' and 'w'. Form member 128 serves two functions, the first being to provide a stiffened base upon which bag 20 can tend preferentially to stand, and which may tend to aid in discouraging bag 20 from tipping over as easily as it might otherwise do. The second is to provide a forming edge to base 26 by which to pre-determine the fold line, or lines, at which bag 20 will tend to want to bend when being folded up. This may tend to discourage the tight-rolling of bag 20, and to encourage repeatable panel folding to and from the convenient folded form shown in Figures 3a - 3g.
Form member 120 need not be a continuous monolithic panel. It could be an open frame, or a peripheral member sewn in place to provide a reinforced edge. In one embodiment, even without form member 120, the seaming at the edge of insulated base panel 26 may tend to yield a natural fold location at which bag 20 may tend to prefer to bend or fold. The inclusion of member 120 may tend to strengthen or to enhance this tendency. Modestly sized feet, stand offs, or pads, 102, may optionally be provided to the underside of panel 26.
Further, form member 120 may, by itself. tend to have a greater flexural stiffness that the adjacent layer of insulated material, and when taken together the resultant bi-laminar, or possibly multi-layered assembly, has a combined flexural stillness that may tend to be significantly stiffer than any other portion of bag 20.
Lifting members, or carrying members. in the nature of straps, or web bands 46, 48, are sewn up the outside faces of side wall panels 22 and 24, having their roots at the seamed junction between bottom panel 26 and the side all panels 22, 24. Each of bands 46, 48 has a central portion 104, 106 that extends upwardly beyond the upper margins of the sidewall panels to provide a grasping, or carrying portion that can be held or place over a user's shoulder, as in Figure 1.
Auxiliary securement straps 50, 52 have a root end sewn into the upper region of the seam between panels 22 and 24, at a height near the height of closure member 28. The distal ends of straps 50, 52 bear velcro patches 110, suitable for securing in to the trunk fabric of an automobile (or, alternatively, mating velcro patches can be mounted inside the automobile for this purpose). When not in use, the ends of straps 50, 52 mount to mating velcro patches 112 located on the outward face of front side panel 22. Straps 110 could as easily be oriented to face in the other direction, and to mate with patches sewn on rear panel 24.
Alternate Embodiments In the alternate embodiment of Figure 9a, an alternate insulated base panel 126 has the same structural and thermal properties as base panel 26 in general, but differs in that rather than being rectangular in plan view, base panel 126 has a length, or long dimension, indicated as 'b2' and a width indicated as 'w'. These dimensions need not be the same as 'b' and 'w' indicated above, but may be. In this case the ends of panel 126 are not squared, but rather are mitred at an angle a relative to the perpendicular to the long edges. The length along each of the mitred edges is then given as 'a2'. In this case the half width of base panel 126 is not a2 but rather a2 cosa. The periphery of base panel 126 is 2(b2 + 2a2).
The adjoining side panels are again taken to be 'X' wide, and 'Y' high, and to be of the same general insulated construction as side wall panels 22 and 24, as shown, for example, in Figure 5. The length of the lower margin 124 of each of the adjoining side panels 126 is then (b2 + 2a2). Each panel will then have a "large fold" 128 and a "small fold" 130.
Large fold 128 is a nominal indication of where there would be a fold in the side wall of the bag in the fully unfolded condition ready for filling with diverse objects, if a sharp crease were made. In actual use, the corner will not be creased, but rather will tend to take on a more rounded, or radiused form, and the bag will tend to conform to the shape and bulkiness of objects placed in it, so the actual corner of the bag may have a bulging appearance rather than a sharp corer. Small fold 130 indicates the actual location of a told that is made when the bag is in a collapsed state and folded for storage.
The angle (3~ of small fold 130, when the bag is folded for storage, will then tend be roughly equal to the bisector of the angle between the extension of the horizontal fold line defined by the edge of base 126 and the mitred edge, namely'/Z(90 - a).
Base panel 126 need not necessarily be a straight sided polygon, as is base panel 26, but could have somewhat rounded, oval or irregular ends. However, in such a case the end fold may tend to be puckered, and may tend not to lie as flat as might otherwise be considered desirable or preferable. However, a straight sided polygon is advantageous, and a square-cornered (i.e., rectangular) end is preferred since it may tend to facilitate manufacture and efficient use of materials and reduced waste cuts.
Bag 20 is a "double fold" bag. That is, base panel 26 is folded flat at a first fold (the offside edge of base panel 26), and then side panels 22 and 24 are bent about the second fold (the nearside edge of base 26). In alternate embodiments, a soft sided, collapsible and foldable insulate single-fold bag could be produced, or a triple-fold, or more, bag could be produced.
An example of a single fold bag 140 is shown in Figures l0a - lOg, the views corresponding generally to the views of double fold bag 20 shown in Figures 3a - 3g respectively. Except as otherwise indicated, bag l40 has the same general construction as bag 20, having insulated side wall panels 142, 144, and an insulated base panel 146, with a similar closure member 148 and optional liner similar to liner 32. Bag 140 differs from bag 20 in being a single fold bag, rather than a double fold bag, and has changes in dimension and aspect ratios accordingly. In place of the arrangement of retainer 34, a retention member 150 may be mounted near the lower margin of the front panel 142, and another, mating, retention member 152 may be mounted near the upper edge of the front panel, the two mating when the base panel is moved to a collapsed position in which it is laid over against side panel 142.
An example of a triple fold bag 160 is shown in Figures lla - llg. Figure lla shows triple fold bag 160 in a collapsed, or flattened condition immediately prior to folding into the storage position (or, alternatively and equivalently, immediately after being unfolded, and before filling). Bag 160 is presented as being symbolic of not only a bag having three folds. In general, for a bag, such as bag 160, having three or more folds, the retention member 178 would be located on the front face 164, roughly the width of two folded panel regions below the upper edge of the front face with the second retention member being mounted near or at the upper edge, such that, when folded the two parts 178 and 174 would tend to mate. An example of a single fold bag is illustrated in Figure 10a. An example of a triple fold bag is shown in Figure 11 a.
In the examples discussed so far, the upper edge of a bag having rectangular sidewall panels is L; = 2(a; + b;), whether i is 1 or 2. As shown in Figure 9b, the side panels of bag 20 need not be made from rectangular sheets, but could be made from sheets that are of a different shape. such as the trapezoidal side panel sheets 180. In this case, the resultant bag 182 would tend to have an upper edge 184 for which the length LZ would tend to be greater than the sum of the b + 2a;, or, put generically, where L; is greater than half the total periphery of the base panel 186. This may tend to yield a more flared appearance when the bag is seen in an unfolded side view, and may tend to yield a larger access opening, such as may permit objects of greater relative size to be introduced into the insulated spaced.
Another alternate embodiment of foldable insulated container, identified as insulated bag 200 is shown in Figures 12a through 15e. In this example, bag 200 may include first and second insulated panel members 202, 204 as before, such as may have an inside lining 82, an outside covering 80 and a layer of insulation 84 between lining 82 and covering 80.
That layer of insulation 84 may be an open or closed cell foam. Further, bag 200 may include a base panel 212 having the same construction as described above, including a stiffening batten 120 such as may be located between an outside covering layer 116 and insulation layer 118.
As such bag 200 may be taken as having substantially the same basic shape and construction as bag 20 and the other alternate embodiments of bags described above.
However, bag 200 may differ from the other bags described herein to the extent that bag 200 may have mounted to base panel 212 a trailing apparatus 220, such as may permit bag 200 to be pulled in train, rather than carried clear of the ground. That is to say, bag 200 may include one or more ground interface members 224, 226 operable to permit bag 200 to be drawn over a surface. Those ground interface members may be part of an undercarriage 230, which may include one or more rolling contact members, such as wheels 232, 234, which may be mounted to wheel mounts in the nature of shafts or axles 236, 238.
In one embodiment, undercarriage 230 may be retractable. That is, wheels 232 and 234 on axles 236, 238 may be movable between a deployed, or down, position suitable for supporting bag 200 while in motion (such as shown for example, in Figures 12a - 12f and 15~; and a retracted, or up, position, such as when bag 200 is folded in a storage condition, or is resting in a location in which members for facilitating travel of bag 200 are not required (such as shown, for example, in Figures 13a -13d and 14a -14c).
Undercarriage 230 may also include support members, such as may be in the nature of rests, or stand-offs, or props or struts, such as may be identified as a foot or feet 240. These supports (or support, as may be) may be co-operable with the trailing members, such as wheels 232, 234 to provide a base upon which bag 200 more generally may rest when in the unfolded and opened out condition for carrying articles. When bag 200 is towed, bag 20 may tend to have an inclined attitude relative to the axis of rotation of wheels 232, 234, and when so inclined, feet 240 may tend to be lifted clear of the ground (or other surface) upon which wheels 232, 234 may roll. It may be that feet 240 and axles 236, 238 are formed from a continuous member 242, such as a rod or wire, bent at one end to form a foot 240, and formed at the other end to define axle 236 or 238, as may be. Each member of undercarriage 230 may also include a stationary mount member or housing 244, connected to base panel 212, and into which member 242 is mounted in spring loaded biased engagement. Mount member 242 may include detent formations, such as at 246 and 248, into which member 242 is biased in the retracted and deployed positions respectively. Wheels 232, 234 are axially reciprocal, with the shafts, namely axles 236, 238 being mounted in spring loaded sockets of housings 244. These sockets may require an axial pull and an angular rotation to overcome the detent in order to deploy wheels 232 and 234, and may be biased to the "down" position unless held in the up position be the detent.
For bag 200, folding may be in the accordion manner, as opposed to roll folding described above. To that end, a temporary, releasable securement 250, such as may be in the nature of a hook and eye fastening member, may be mounted to the lower margin 252 of the adjacent side, and a mating hook and eye fastener 254 may be mounted to the facing portion of the side above the first fold as indicated at 256. Similarly, a half fold crease 258 is located on the lower margin of the other side, permitting the bottom panel to fold flat a full fold. When fully folded, with the wheels retracted, the package may be hung on a display hanger or stored in a comparatively compact package.
Unfolding may generally proceed from the fully folded position, or condition, of Figure 13a, to the unfolded position of Figure 14a, in which bag 200 may be in a generally flat condition, to Figure 15a, in which the wheels are moved to a deployed position, to Figure 12a, in which bag 200 is filled, and has its wheels down, ready for pulling.
In other embodiments, the undercarriage assembly may include skids, skis or runners in place of wheels, and in those embodiments the long axis of the skids, skis, or runners may be oriented perpendicular to the axis of rotation of wheels 232, 234.
Although various the embodiments have been described and illustrated, the principles of the present invention are not limited to these specific examples, which are given by way of illustration. Since changes in or additions to the above-described embodiments, or both, may be made without departing from the nature, spirit or scope of the invention, the invention is not to be limited to those details.
