-
FIGS. 1 a-1 f 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 limited to the option shown, a bi-fold door or a
fabric cover 18 with azipper 28. Thezipper 28 may take any direction or form. Thecover 18 may be additionally complicated with decorative or functional improvements including designs andpockets 42. - The container may be
solid panel 32, perforatedpanel 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 aswheels 52, handles 50, etc., as shown inFIGS. 8 and 9 . - The triangulated
panels 32 typically two or more per container have two creasedminor panels 32 lesser than, equal to or greater than 45 degrees, as shown inFIGS. 2 a-2 f. Creating a container with an angle of less than 45 degrees, for example, allows it to nest. - The preferred mechanism 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 each crease in eachpanel 32, as shown inFIGS. 3 a and 3 b. Although a similar result may be obtained from other similar flexing members springs, sprung steel plastic carbon, elastic or other materials, as shown in FIGS. 13 and 14. The curved tempered steel hold several advantages due to its mechanical properties. - In its straight state (
FIG. 3 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 it that there is not manual lock or intervention on behalf of the user to achieve this condition, it is automatic an additional advantage of the steels ‘automatic’ nature is that it can be hidden inside a container. Additionally, when the steel is folded, as shown inFIG. 3 b, although it retains 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 or soften ensuring good quality and product life. - Although the
aforementioned panel 32 assembly can be made from sprung steel, and assembledpanels 32 of a suitable rigid material, plastic, wood, laminate, etc. with conventional hinged hinges and rivets, modern manufacturing materials and processes allow for the consolidation of threepanels 32, two hinges, assorted rivets and a minimum of two locating anchors and accordant ties down to one simple strong component, whose additional features are identified below. - In the preferred embodiment, the
panel 32 is manufactured in one piece with a suitable thermoplastic material including but not limited to polypropylene, copolymer or homopolymer or polyethylene. An example of thepanel 32 is shown inFIGS. 11 and 12 . - The
rectangular panel 32 essentially flat on one side (seeFIG. 12 ) with the exception of raised rivet bosses and required holes for molding, has on its other side a series of raisedribs 34 constructed in accordance with sound engineering principles to best strengthen the part for the loads it will see and also provide a recess within which the sprungsteel length 30 can operate and deflect. Additionally, there are raisedribs 34 neared the perimeter of the part and stepped inboard of the part. This is in order that thepanel 32 can sit within a stitchedfabric pocket 42. A stitchedfabric pocket 42 typically has excess material inside and stepping the perimeter wall in allows a recess within which the excess material can sit. The raisedribs 34 provide a protective tack within which the steel can sit. - The
single panel 32 is able to hinge along a predetermined axis via the thinning of the material in a particular direction. Additionally, to prevent thepanel 32 from hinging in the opposite direction which would be undesirable, ‘T’ shapedposts 38 extrude up from the underside on either side of the hinge and butt against it preventing hinging in the opposite direction. - The
steel length 30 is inserted from one open end of thepanel 32 and is captured via ‘pass thru 40’ details that are made in the same piece as themain 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 enter, once the steel is fully inserted the flexing member returns to its origin and prevents the steel from coming out. - The pass thrus 40 at each end are identified due to their curved inner surfaces, that conform to the steel, effectively centering the steel in the track of the
panel 32. It is notable that the center pass thru 40 (bridging the live hinge) is of a different profile to the end pass thru 40. - The center pass thru 40 inner profile is straight deviating from the curvature of the steel which it bridges, this is because as the steel bends the profile of the steel transforms from curved to bent in the bent area. This also makes the steel wider. The straight 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. it is flat and therefore wider.
- When the steel is bent in half, it bends along ‘point break’ lines. These are the visible edges of the underside of the center pass thru 40. Tuning the location of these edges effects performance. Specifically, the closer the edges are to each other the easier it is 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. The 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 break opening to different dimension specific to each container, a uniformity of force required to deploy or fold down all thebags 10 can be achieved because the bend of the steel does not precisely follow the bending profile of thepanels 32. It effectively shortens as it bends in relation to thepanel 32, therefore the steel cannot be affixed to thepanel 32 but must ‘float’ in order to allow thepanel 32 to bend. - The flexing
panels 32 may be joined in combination in any number of ways to assemble novel containers, for example, panels can be joined to homa frame, i.e. an extruded fluted plastic, or acardboard box base 12, or a folded extruded pp or pe ‘corex’base 12, or awire base 12, or awire base 12 covered in fabric or a vacuum formed or otherwise moldedbase 12 including injection molding. The materials forbases 12 can also be used as a side in any and all combinations. Furthermore, although it is desirable for the flexingpanel 32 itself to have well defined hinges thepanels 32 of the overall five to six sided container, may be joined by hinges, loose fabric hinges; or eachpanel 32 in any combination may reside inside afabric pocket 42. - The
collapsible sidewalls 46, and fixedsidewalls 46 are pivotally attached to thebase 12. Thebase 12 is slipped into a box shaped fabric skin 18 (i.e. the bag 10). Eachpanel 32 of theskin 18 is doubled up in anouter skin 18 and a liner. This essentially forms pockets 42. Thepanels 32 simply slip into thepockets 42, therefore thepanels 32 in this embodiment are joined via thepockets 42 which form fabric hinges; in a hard case they could be directly affixed to each other. The rivet holes 44 in thepanels 32 are anchor points to affix load bearing items, i.e. handle 50 straps and the like. - In regard to the
curved steel length 30, it is preferably spring steel, itslength 30 is dictated by thepanel 32 to which it is affixed, its thickness is 0.005″ to 0.010″, 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 skilled in the art without departing from the spirit and scope of the invention except as it may be described by the following claims.
