Preferably, the first recess 36a and the second recess 36b extend between the first element 54 and the center element 48, and the second element 56 and the center element 98, respectively, and intersect the first and second hinges 58, 60, respectively. The first and the second hinges 58, 60 each preferably have posts 38 which allow the first and the second hznges 5$, 60 to only fold in one direction.
'The present invention pertains to a method for u$ing a bag ~Ø The method camprases the steps of forming a storage space 20 with a base 12, a first rigid collapsible wall 14 in pivotable relationship with the base 12, a second rigid collapsible wall 16 in pivotable relationship with the base 12 and in spaced relation with and opposing the first rigid wall, and a skin 18 disposed about the first wall 14 and the second wall ~.6 and connected to the S base 12 where the first and second walls 14, 16 are maintained in a flat planer orientation essentially perpendicular with the base I2. There is the step of folding the first walk 14 and the second wall 16 onto and essentially in parallel with the base 12 and essentially eliminating the storage space 2C).
Preferably, the forming step includes the step of forming a box about the stoxage space 20 with. a third wall 22 and a fourth wall 24 opposing the third wall 22, a top opposing the base 12, and the first and second walls l4, 16 and the base 12; and wherein the folding step includes the step of folding together the first, second, third and fourth walls 14, Ih, 22, 24 and the top auto and within the perimeter of the base 12. The method includes the step of holding the first, seas~nd, third and fourth walls 14, I6, 22, 24, and the top onto the base 12'with a restraining mechanism 2~ in a collapsed state. Preferably, the folding step includes the steps of folding the first wall 34 onto itself as it is folded onto the base 12, and falling the second, wall 16 onto itself as it is folded onto the base 12.
In the preferred embodiment, the collapsed container may collapse down to 92~ of its erected volume, and remain in a collapsed position with out the aid of latches dr locks, merely pullinrg an the open container allows the container to snap open and remain in an open stable rigid state without the use of latches or locks.
Figures la-If show a schematic in its purest form of the basic collapsing geometry.
The container may remain in an open state or optionally have some method of closure, including but not lim~.ted to the S option shown, a bi-fold door or a fabric cover 1$ with a zipper 28.
The zipper 28 may take any direction or form. The cover 28 may be additionally complicated with decorat~.ve or functional improvements including designs and pockets 42.
The container may be solid panel 32, perforated panel. 32, wire frame covered in fabric, panels covered in fabric or any combination thereof. The container may be outfitted with components for additional functionality such, as wheels 52, handles 50, etc., as shown in figures 8 and 9.
The triangulated panels 32 typically two ar mvre per container have two creased minor panels 32 lessex than, equal to or greater than 4$ degrees, as shown in figures 2a-2f. e.reating a container with an angle of less than 45 degrees, for example, allows it to nest.
The preferred mechani$m to allow semi automatic erection of the container is via a tempered curved steel length 30, similar to those typically found in steel retracting rulers, set approximately at 45 degrees to eaoh crease ~.n each panel 32, as shown in figures 3a arid 3b. Although a similar result may be obtained from other similax flexing members springs, sprung steel plastic carbon, elastic Qx~ other materials, as shown in figures 13 .,~~..~..,~.,_vm..-~ ___ ___..w~_,~_ ~_...__ __.
_$_ and 14. The Cuzved tempered steel hold several advantages due to its mechanical properties.
Tn its straight state (figure :~a) , the steel. has a certain amount of beam strength and remains entirely rigid and true, this is useful to achieve and crispness and rigidity to the container, of significant additional benefit a,t that there is not manual lock or intervention on behalf of the user to achie~re this condition, it is automatic an additional advantage of the steels ' automatic' nature is that it can be hidden inside a container.
to Additionally, when the steel is folded, as shown in f~.gure 3b, although it xetains some tension, it is relatively easy to keep in any convenient position. Lastly, due to it being sprung steel. it is in theory eternal and will never fatigue <>r soften ensuring good quality and product life.
Although the a~orementioned panel 32 assembly can be made from sprung steel, and assembled panels 3~ of a suitable rigid material, plastic, wood, lam~.nate, etc~ with conventional hinged hinges and rivets, modern manufacturing materials and processes allow for the consolidation of three panels 32, two hinges, 2~ assorted rivets and a min~.mum of two locating anchors and accordant ties down to one simple strong component, whose additional features are identified below.
rn the preferred embodiment, the panel 32 is manufaotuxed in one piece with a suitable thermoplastic material including but not limited to polypropylene, copolymer or homopo7.ymer ar polyethylene. An eXample of the panel 32 :l~s shown in figures 11 and 12.
_g_ The rectangular panel 32 essentially flat on one side (see figure 12) with the exception of raised rivet bosses and reguired holes for molding, has on .its other side a series of raised ribs 34 constructed in acooxdance with sQ~xnd engineering principles to best strengthen the part for the loads it will see arid also provide a recess within which the sprung steel ~.ength 30 can operate and deflect. Additionally, there are raised ribs 34 neared the perimeter of the part and stepped inboard of the part.
This is in order that the panel 32 can sit within a stitched fabric pocket ~2. A stitched f8bric pocket 42 typically has excess matez~ial inside and stepp~.ng the perimeter wall in allows a recess within which the excess material can sit. The raised ribs 34 provide a protective tack w~ahin which the steel can sit.
The single panel 32 is able to hinge along a 1.5 predetermined axis via the thinning of the material in a particular direction. Additionally, to prevent the panel 32 frarn hinging in the opposite direction which would he undesirable, TT' shaped posts ~8 extrude up from the underside on either side of the hinge and butt aga~.r~st it preventing hinging in the opposite direction.
The steed. length 30 is ins,~rted from one open end of the panel 32 and is captured via °pass thru 40' details that are made in the same piece as the main panel 32 and capture the steel, The receiving end of the first pass thru 40 has a flexing member on its end that depresses to allow the steel. to enterr once the steel. is fully inserted the flexing member returns to ita origin and prevents the steel from coming out.
~Z~~
The pass thrus 40 at each end are identified due to their curved inner surfaces, that conform to the steel, effectively c8ntering the steel in. the track of the panel 32. It is notable that the center pass thru 40 (bra,dging the ~.ive hinged is of a different profile to the end pass thru 40.
The center pass thru ~0 inner profile is straight deviating from the curvature of the steel whivh it bridges, this is becau$e as the steel bends the profile of the steel transforms from cursed to bent in the bent area. This also makes the steel, wider.
The strazght pass thru 40 accommodates this variance, The track the steel sits in is also wide enough to accommodate the steel when the center is bent, i.e. i.t is flat and th~:refore wider.
When the steel is bent in half, it bends along ' point break' lines. These are the visible edges of the underside of the ~5 center pass thru 40. fiuning the location of these edges effects performance, Specifically, the closer the edges are to each other the easier it zs for the steel to deform and bend in half, conversely the further way they are from each other, the more resistant the steel is to bending. P.che aforementioned is important, for example, a preferred embodiment of three different sizes of luggage, the smaller sizes have less leverage in their panels 32 to bend the steel (presuming the steel is of the same exact dimension and specification in each size of case. Therefore, by tuning the point breal~ opening to different dimension specific to each container, a ura~.formity of force required to deploy ox fold down all the bags 10 can be achieved because the bend of the steel does not precisely follow the bending profile of the panels 32. It effectively shortens as it bends in relation to the panel 32, - ~. J. ..
therefore the steel cannot be affixed to the panel 32 but must 'float' in order to allow the panel 32 to bend.
The flexing panels 32 may be joined in combination in any number of ways to assemble novel containers, foz example, panels can be ~oiried to homa frame, i.e. an extrv.ded fluted plastic, or a cardboard box base 12, or a folded ~sxtruded pp or pe 'carex' base 12, or a wire base 12, or a wire base 12 covered in fabric or a vacuum formed or otherwise molded base 12 inc~.uding injection molding. The materials for bases 12 can also be used as a side in any and all combinations. Furthermore, although it is desirable for the flexing panel 32 itself to have well defined hinges the panels 32 of the overall five to six s~.ded container, may be j dined by hinges, loose fabric hinges; or each panel 32 in any combination may reside inside a flbric pocket 42.
The Collapsible sidewalk 46, and fixed 9idewalls 46 are pi~rotalLy attached to the base 12. The base 12 is slipped into a box shaped fabric skim 18 (i_e. the bag 1D). Each panel 32 of the skin 18 is doubled up in an outer akin 18 and a liner. This essentially forma pockets 42. The panels 32 simp7.y slip into the 2o pockets ~2, therefore the panels 32 zn this embodiment are joined via the packets 42 which form fabric: ha.nges; in a hard case they could be directly affixed to each other. The rivet holes 44 in the panels 32 are anchor points to affix load bearing items, i.e.
handle 50 straps and the like.
Zn regard to the curved steel length 30, it is preferably spring steel, its length ~0 is dictated by the panel 32 to which it -ia-is affix~d, its thickness is 4.005" to O.OIOT', its width is 0.5'~' to 1".
Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skil.l.ed in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.

The single panel 32 is able to hinge along a 1.5 predetermined axis via the thinning of the material in a particular direction. Additionally, to prevent the panel 32 frarn hinging in the opposite direction which would he undesirable, TT' shaped posts ~8 extrude up from the underside on either side of the hinge and butt aga~.r~st it preventing hinging in the opposite direction.
The steed. length 30 is ins,~rted from one open end of the panel 32 and is captured via °pass thru 40' details that are made in the same piece as the main panel 32 and capture the steel, The receiving end of the first pass thru 40 has a flexing member on its end that depresses to allow the steel. to enterr once the steel. is fully inserted the flexing member returns to ita origin and prevents the steel from coming out.
~Z~~
The pass thrus 40 at each end are identified due to their curved inner surfaces, that conform to the steel, effectively c8ntering the steel in. the track of the panel 32. It is notable that the center pass thru 40 (bra,dging the ~.ive hinged is of a different profile to the end pass thru 40.
The center pass thru ~0 inner profile is straight deviating from the curvature of the steel whivh it bridges, this is becau$e as the steel bends the profile of the steel transforms from cursed to bent in the bent area. This also makes the steel, wider.
The strazght pass thru 40 accommodates this variance, The track the steel sits in is also wide enough to accommodate the steel when the center is bent, i.e. i.t is flat and th~:refore wider.
When the steel is bent in half, it bends along ' point break' lines. These are the visible edges of the underside of the ~5 center pass thru 40. fiuning the location of these edges effects performance, Specifically, the closer the edges are to each other the easier it zs for the steel to deform and bend in half, conversely the further way they are from each other, the more resistant the steel is to bending. P.che aforementioned is important, for example, a preferred embodiment of three different sizes of luggage, the smaller sizes have less leverage in their panels 32 to bend the steel (presuming the steel is of the same exact dimension and specification in each size of case. Therefore, by tuning the point breal~ opening to different dimension specific to each container, a ura~.formity of force required to deploy ox fold down all the bags 10 can be achieved because the bend of the steel does not precisely follow the bending profile of the panels 32. It effectively shortens as it bends in relation to the panel 32, - ~. J. ..
therefore the steel cannot be affixed to the panel 32 but must 'float' in order to allow the panel 32 to bend.
The flexing panels 32 may be joined in combination in any number of ways to assemble novel containers, foz example, panels can be ~oiried to homa frame, i.e. an extrv.ded fluted plastic, or a cardboard box base 12, or a folded ~sxtruded pp or pe 'carex' base 12, or a wire base 12, or a wire base 12 covered in fabric or a vacuum formed or otherwise molded base 12 inc~.uding injection molding. The materials for bases 12 can also be used as a side in any and all combinations. Furthermore, although it is desirable for the flexing panel 32 itself to have well defined hinges the panels 32 of the overall five to six s~.ded container, may be j dined by hinges, loose fabric hinges; or each panel 32 in any combination may reside inside a flbric pocket 42.
The Collapsible sidewalk 46, and fixed 9idewalls 46 are pi~rotalLy attached to the base 12. The base 12 is slipped into a box shaped fabric skim 18 (i_e. the bag 1D). Each panel 32 of the skin 18 is doubled up in an outer akin 18 and a liner. This essentially forma pockets 42. The panels 32 simp7.y slip into the 2o pockets ~2, therefore the panels 32 zn this embodiment are joined via the packets 42 which form fabric: ha.nges; in a hard case they could be directly affixed to each other. The rivet holes 44 in the panels 32 are anchor points to affix load bearing items, i.e.
handle 50 straps and the like.
Zn regard to the curved steel length 30, it is preferably spring steel, its length ~0 is dictated by the panel 32 to which it -ia-is affix~d, its thickness is 4.005" to O.OIOT', its width is 0.5'~' to 1".
Although the invention has been described in detail in the foregoing embodiments for the purpose of illustration, it is to be understood that such detail is solely for that purpose and that variations can be made therein by those skil.l.ed in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
